Description
TECHNICAL FIELD
[0001] The present invention relates to a hand-retaining device,
such as for example a glove or a hand strap which can be fastened
on the hand, which hand-retaining device has, between the thumb and
forefinger, a coupling element for coupling to a pole grip, in
particular for walking sticks, trekking poles, downhill ski poles,
cross-country ski poles and Nordic walking poles. Such a
hand-retaining device is preferably suitable for fastening in a
releasable and self-latching manner on a pole grip with a grip body
with a hook-like device.
PRIOR ART
[0002] A pole grip as is known, for example, from U.S. Pat. No.
5,516,150, has a hook provided on it, and a rigid bow-like device
formed from a curved metal element is provided on the associated
glove, in the region between the thumb and forefinger. The bow has
its long leg introduced into a narrow slot of the hook, and the
hook-like device fixes the bow, and thus the glove, on the pole
grip.
[0003] Provision is made here for the slot to be widened slightly
at the bottom of the hook, which means that, when the bow is moved
into the hook, it initially forces the two legs of the hook apart
from one another to a slight extent, and that it is only when the
bow has been pushed into the widened portion that the legs spring
back into the original position.
[0004] Elastic deformation of the hook-like device is thus used in
order to fix the bow easily in the hook and to avoid the situation
where the bow can easily slide out of the hook.
[0005] One of the problems with such devices is the fact that
repeated deformation of such components, which are usually formed
from plastic or metal, is undesirable on account of signs of
fatigue.
[0006] There is also the particular problem of the elastic
deformation behavior of materials being highly dependent on
temperature. It is thus also the case that the fixing action which
is achieved by the deformation is neither adjustable nor constant
for different temperatures.
[0007] This is absolutely unacceptable in the sporting arena in
particular, since very large differences in temperature are
unavoidable, on the one hand, on account of different weather
conditions and, on the other hand, as a result of heating or
warming up during use.
DESCRIPTION OF THE INVENTION
[0008] This is where the invention comes in. The object of the
invention is thus to provide a hand-retaining device which has
improvements over the prior art and is intended for fastening in a
releasable and, in particular preferably, self-latching manner on a
pole grip with a hook-like device. The concern here in particular
is to improve such a hand-retaining device for use in conjunction
with a pole grip for walking sticks, trekking poles, downhill ski
poles, cross-country ski poles and Nordic walking poles, these
having a grip body with a hook-like device for fastening a
hand-retaining device in particular in the form of a hand strap or
of a glove. This object is achieved in that the hand-retaining
device, for example a glove or a hand strap which can be fastened
on the hand, has as a coupling element, between the thumb and
forefinger, a movable, that is to say inherently flexible, loop
which is suitable for fastening the hand-retaining device on a
hook-like device of a pole grip. Such a hand-retaining device
proves to be successful, in particular, when used in conjunction
with pole grips in which displaceable or rotatable latching-in
means are arranged in the region of the hook-like device such that
a loop-like, ring-like or eyelet-like device, which is inserted or
pushed into the hook-like device preferably essentially from above
and is provided on the hand-retaining device, is fixed in the
hook-like device with self-latching action.
[0009] Rather than, as has usually been deemed absolutely necessary
in the prior art, providing a stiff element as the coupling
element, in order that this element can be pushed at all over the
hook-like device without the aid, for example, of the other hand,
the core of the invention thus consists in providing an inherently
flexible, that is to say movable, element in the form of a simple
loop. This means that the coupling element is considerably less
troublesome both during use, when the hand-retaining device is
fastened on the pole grip, and when the hand-retaining device is
not fastened on the pole grip. Surprisingly, such a movable loop is
nevertheless readily capable of absorbing the high forces which
occur and, in addition, it allows optimum guidance even when the
pole grip is not actively being gripped. The loop here is
preferably fastened on the hand-retaining device such that, as a
result of its remaining inherent rigidity, it projects between the
thumb and forefinger such that it can easily be pushed over the
hook-like device.
[0010] Hand-retaining devices which are particularly well suited
for being used together with an abovementioned pole grip are
therefore those which have a movable loop or eyelet in the V region
between the thumb and forefinger. Such a hand-retaining device
interacts with a pole grip as described above in the manner of a
key and lock or plug and socket. The small loop is particularly
comfortable and is not obtrusive, in which case such a glove or
such a hand-retaining device is also suitable for biathlon or the
like.
[0011] The loop, in particular, is a loop which is made of a
flexible material with a sufficient level of inherent rigidity to
stabilize it in a position in the space between the thumb and
forefinger, which allows it to be introduced straightforwardly over
the hook or retaining peg and which, conversely, cannot be felt, or
can only barely be felt, during use. Possible examples of loops are
those made of a cable or wire, which may be surface-coated.
Examples of other elements which are basically also suitable to be
used as material for such loops are textile fibers which are
encased in a woven-fabric sheath, have limited expansion capability
and are stable in relation to tension, or retaining elements which
are braided in a cord-like or cable-like manner, using
corresponding materials such as for example Aramid, Kevlar,
Dyneema, etc. If use is made of such materials for the loop, cords
with a thickness of 1-5 mm are most suitable, a thickness of 2-3 mm
being preferred. In order to impart a sufficient level of inherent
rigidity to the loop, such cords may be provided with stiffening
elements, for example a "core" made of monofilament nylon or
in-woven fibers consisting of a relatively stiff material, for
example nylon or thin metal wires. It has been found that a cable
with a thickness in the range of 0.5-2.5 mm, preferably in the
range of 1-2 mm, is particularly suitable.
[0012] The, for example, braided or twisted cable can be coated
with another material, for example copper or plastic. As an
alternative, it is possible to produce the loop from a plastic
material, also, for example, in band form, preferably from a
fiber-reinforced plastic, for example polyamide, PE, PP or the like
being suitable, in which case combined materials with a layered
construction are also possible, and in particular preferably
reinforcements with fibers for example made of Aramid may be
provided.
[0013] The loop preferably projects by between 5-20 mm, in
particular by between 5-10 mm, beyond the V region between the
forefinger and thumb. In this case, the direction of the loop, to a
certain extent, runs essentially along the angle bisector between
the thumb and forefinger.
[0014] It is possible for the loop to be adjustable, this
adjustability being provided, on the one hand, in order to adjust
the length specifically to the user, but also, when the loop is not
required, in order to retract the same so that it cannot be felt
during use. It is also possible for the loop to be stowed, when not
in use, in a small pocket, which is provided for this purpose in
the hand-retaining device, likewise in the V region between the
forefinger and thumb. This latter possibility is particularly
straightforward in design terms and, as far as the inherent
rigidity of the loop is concerned, on the one hand, the loop can be
accommodated in such a pocket and, on the other hand, if not
specifically manipulated, it remains concealed, essentially without
any special measures having to be taken in the pocket, during use
of the hand-retaining device.
[0015] In order to ensure that the forces which act on the loop are
coupled as well as possible to the hand-retaining device, the
wire/the cable of the loop can be guided in the direction of the
wrist, at least in part, in or on the hand-retaining device. It is
also possible to provide a combination with an adjustable device
like that described in DE 19751978 C2, the disclosure of which is
expressly included in this respect. Instead of the rigid connecting
element cited in this document, a flexible loop is simply provided.
The loop is considerably less troublesome in particular when the
glove is used without the pole.
[0016] The hand-retaining device according to a first embodiment is
thus preferably characterized in that the loop comprises an
inherently movable cable or bow or a flexible plastic cord with
inherent rigidity. It is preferably here for the loop to be
fastened in an essentially non-movable manner on the hand-retaining
device, but the loop is itself of movable design.
[0017] As has already been mentioned, the hand-retaining device may
be a glove, or else a hand strap which has three openings and which
can be fastened on the hand in particular preferably with the aid
of a touch-and-close fastener, a first opening being provided for
the thumb, a second opening being provided for the other fingers or
the back of the hand, and a third opening of the hand strap being
provided for the wrist.
[0018] In order to allow the loop to be introduced as easily as
possible onto the hook-like device, and in order to ensure ideal
force transmission, it proves to be advantageous if the projecting
part of the loop on the hand-retaining device is arranged
essentially in the plane which, when the hand is open and stretched
out, is defined by the thumb and forefinger.
[0019] As has already been mentioned, the loop is preferably a loop
made of a plastic material, preferably a plastic fiber which is
oriented and/or has limited expansion capability, in particular
preferably based on polyethylene, in particular preferably oriented
polyethylene, e.g. Dyneema.RTM., polyamide, polypropylene, Aramid
or a combination of these materials. Preferred combinations are
ones in which a core made of, for example, oriented polyethylene
fibers is enclosed by braided synthetic fibers in the manner of a
braided sleeve.
[0020] A further preferred embodiment of the hand-retaining device
according to the invention is characterized in that the length of
the loop is adjustable, it being possible, in particular
preferably, for the loop to be recessed essentially fully into or
on the glove when not in use. As an alternative, it is possible for
the hand-retaining device to contain a niche or pocket into which
the loop can be inserted when not in use.
[0021] In order to allow the loop to be fastened as well as
possible on the hand-retaining device, in particular on the glove,
it proves to be advantageous if, at least over a length of 2-15 cm,
in particular preferably of at least 5 cm, the non-exposed region
of the material of the loop, at both ends, is adhesively bonded,
sewn or woven in or on the hand-retaining device, and/or in the
form of an intermediate layer of the hand-retaining device, or is
fastened in some other way between the outer layers of the
hand-retaining device.
[0022] The material of the loop is also fastened on the
hand-retaining device, for example, via a band strip, in particular
made of woven plastic-based textile material with a width of
between 3-30 mm, this band strip being sewn in particular
preferably on the outside of the hand-retaining device, or being
adhesively bonded or sewn to the glove, and the band strip, further
preferably, being arranged in the V between the thumb and
forefinger so as to encircle the back of the hand and the palm of
the hand.
[0023] A further preferred embodiment is characterized in that a
hand strap may be integrated, to a certain extent, in a glove, in
which case the hand strap itself with the movable loop can be used
without the glove and the glove can be used with the hand strap
embedded in it. The hand-retaining device may thus be configured as
a glove in which is arranged, in one or more corresponding
recesses, a hand strap which preferably has three openings and
which can be fastened on the hand, or on/in the glove, in
particular preferably with the aid of a touch-and-close fastener, a
first opening being provided for the thumb, a second opening being
provided for the other fingers or the back of the hand, and a third
opening of the hand strap being provided for the wrist. The hand
strap, in particular preferably, is arranged in the glove such that
it can be adjusted from the outside via a touch-and-close fastener
arranged in the region of the back of the hand. The hand strap can
advantageously be removed altogether from the glove and can be used
without the glove.
[0024] A further preferred embodiment of the hand-retaining device
is distinguished in that, in the rest position, the loop is of
essentially semi-circular or semi-oval form, in particular
preferably with a diameter in the range of 3-10 mm.
[0025] Further preferred embodiments of the hand-retaining device
according to the invention are described in the dependent
claims.
[0026] As has already been mentioned, such a hand-retaining device
can be used, in particular preferably, in conjunction with a pole
grip which has a hook-like device into which the loop can be pushed
with self-latching action. If use is made here, for latching-in
purposes, of a rotatable or displaceable element, there is
essentially no material deformation on the hook in the case of a
self-latching mechanism for fastening a hand-retaining device on
the pole grip; so preferably mechanisms are used in which, when a
loop-like, ring-like or eyelet-like device is pushed into a
latched-in position, a corresponding latching-in means is either
displaced or rotated. It is thus possible correspondingly to
provide a specific elastic mounting arrangement for these
latching-in means, the arrangement, in particular, being less
susceptible to wear, being adjustable, if appropriate, and having a
low level of temperature dependence in respect of the forces. The
hook-like device is arranged in the top region of the pole grip,
e.g. on the hand side, it being the case that the hook-like device
comprises a retaining pin or retaining peg which is arranged
preferably essentially parallel to the pole axis (although a
specific amount of inclination may also be present) and is offset
in the direction of the hand side from the grip body to form an
introduction slot, the depth of the introduction slot being greater
than the width and the thickness of the retaining peg or retaining
pin. Offset does not necessarily mean that the retaining peg or
retaining pin has to project beyond the contour of the grip body;
it is also possible for the retaining peg or retaining pin to be
positioned in a recess which is open toward the top and rear and is
provided specifically for this purpose in the grip body. It has
typically been found that the hook-like device advantageously has a
width in the range of 3-15 mm, preferably in the range of 4-10 mm,
the hook-like device having an essentially oval or rectangular
(possibly with rounded edges) cross section, in particular
preferably at least in certain sections perpendicular to the pole
axis, in which case preferably the short main axis is directed
toward the grip body. The introduction slot typically has a depth
in the range of 5-30 mm, preferably in the range of 10-15 mm. It is
possible here, for example, to provide a slight convexity in the
hook-like device directly opposite the latching-in means.
[0027] The hook-like device may be integrally formed on the grip
body. In particular in combination with the mechanism which is
described hereinbelow, and in the case of which a recess is
provided in the pole grip for accommodating the mechanism, it
preferably proves to be expedient to design the hook-like device as
a separate component. This is then fastened on the grip body via
fastening means, preferably once the mechanism has been inserted
into the recess of the grip body. This can be realized, for
example, by the hook-like device having, beneath the hook, a
fastening plate by means of which the hook-like device can be
fastened on the grip body (for example by means of a screw or rivet
or via a clip mechanism) from the hand side.
[0028] As has already been explained, the grip body is provided,
from the hand side, for example with a recess which accommodates a
displaceably mounted element, in particular preferably in the form
of an arresting block, on or in which latching-in means are
arranged, it being possible for these latching-in means to be
formed either integrally with the arresting block or as a separate
component, and in the latter case this separate component, for
example in the form of a restraining nose, can be connected to the
arresting block either in a fixed manner or via a movable
mechanism.
[0029] The arresting block is advantageously guided such that it
can be displaced parallel to the direction of the recess, but it is
also possible to mount it for rotation. The arresting block is
braced against the hook-like device, which is arranged in front of
the recess, via a spring (this also covering, in general,
resiliently elastic elements), in particular preferably via a
helical spring. This results in the above-mentioned self-latching
mechanism.
[0030] In order that the hand-retaining device can also be
separated from the pole grip again, means should be provided in
order to push the latching-in means back and release the
hand-retaining device from the hook. This is possible, for example,
by it being possible for the arresting block to be displaced from
the outside, counter to the spring force, via at least one
actuating button, the self-latching mechanism being released in the
process, in which case, for this purpose, slots are provided
laterally, in particular preferably in the grip body in relation to
the recess and, via these slots, actuating buttons arranged on both
sides are operatively connected to the arresting block, for example
by a fixed connection being created between these two elements via
a crosspiece or pin.
[0031] It is basically possible for the arresting block to be
fitted in a rotatable or displaceable manner on the grip body by a
wide variety of different methods. It is thus possible, for
example, to design the uppermost region in its entirety, that is to
say, as it were, the head region of the pole grip, as the arresting
block, in which case, to a certain extent behind the same and
fixedly connected to the bottom part of the pole grip, or formed
integrally therewith, the hook-like device is provided so as to
allow a loop of a hand-retaining device to be fixed between the
arresting block and the hook-like device.
[0032] It is possible to provide, in or on the arresting block, at
least one activating button by way of which the retaining means
arranged in the arresting block, preferably in the form of a pin,
can be displaced counter to the spring force, the self-latching
mechanism being released in the process. It is also possible for
the grip body to be provided from the hand side, and from above,
with a recess which accommodates a displaceably and/or rotatably
mounted element in the form of an arresting block in which
latching-in means are arranged, the arresting block being braced in
the downward direction for emergency activation via an axial
helical spring which is arranged in a cavity of the pole grip and
the stressing of which can be adjusted preferably via an adjusting
nut.
[0033] The grip body may be provided, from the top side, with a
recess which accommodates a displaceably and/or rotatably mounted
element, in particular preferably in the form of an arresting
block, on which latching-in means are arranged. If the recess is
provided from above, it is then possible, without obstructing
assembly or installation, to form the hook-like device, for
example, integrally with the grip body, for example in the form of
a simple slot or cutout arranged in the grip body on the hand side.
The arresting block here can be mounted in a rotatable manner about
a horizontal axial element, which is arranged between the hook-like
device and grip body preferably essentially parallel to the plane
of the slot, and it can be braced against the hook-like device,
arranged on the hand side, via a spring, in particular preferably
via a helical spring or a leaf spring. The arresting block can then
be tilted from the outside, counter to the spring force, via at
least one actuating button, the self-latching mechanism being
released in the process, in which case, for example, the actuating
button is provided essentially on the top side of the pole grip,
that is to say the arresting block is exposed, to a certain extent,
from above and a part or portion, or a sub-surface, of the
arresting block forms the actuating button.
[0034] The latching-in means may be designed in the form of a
restraining nose which has a beveled flank toward the top, in
particular preferably as seen in the direction of introduction, and
which, in the position in which it is braced against the hook-like
device, defines, in the downward direction, a region for the
loop-like, ring-like or eyelet-like device which is restricted in
respect of a preferably adjustable force. It is possible here for
this retaining nose to be arranged either on the arresting block
or, as it were opposite, on the hook-like device.
[0035] The latching-in means may preferably be designed in the
manner of a safety mechanism such that, in the event of loading in
the direction of the opening of the hook-like device which goes
beyond a normal usage force, emergency release of the loop-like,
ring-like or eyelet-like device takes place, this being similar to
a mechanism which is also known in respect of ski bindings. This
can be realized either via elastic deformation of this nose, or in
the region of this nose, or else, and this is the preferred variant
because it can be much better controlled and possibly even
adjusted, by the restraining nose being mounted in a rotatable
manner about a preferably horizontal axial element arranged
essentially perpendicularly to the opening direction of the recess.
Rotation in the upward direction, to release the region in the
upward direction, is only possible here counter to a defined and,
as has already been mentioned, preferably adjustable force. The
restraining nose may be braced by way of a leg spring, by way of an
elastomer spring or by way of a helical spring, or by way of a
combination of such resilient elements, into the rotary position in
which it closes off the region, this bracing in particular
preferably being adjustable, in which case safety activation takes
place only under a force of more than 80-250 N. A further analogous
embodiment of the pole grip is characterized in that the
restraining nose is mounted in a displaceable manner, in which case
displacement in the upward direction to release the region is
possible counter to a defined and preferably adjustable force, as
specified above, and the force is preferably ensured via a spring
or a resilient element.
[0036] Moreover, safety activation can also be realized via a
yielding action in the region of the hook-like device. For this
purpose, the hook-like device may be configured such that it can be
displaced or tilted about an axial element, counter to an elastic
force, in the direction of the hand side to release the region. As
an alternative, or in addition, it is possible to provide a
resilient region on the hook-like device on the slot side. This
resilient region can be realized, for example, via a leaf spring or
an elastic portion (specifically a soft elastic polymer portion or
the like).

WAYS OF IMPLEMENTING THE INVENTION
[0046] FIGS. 1a)-f) illustrate different views of a pole grip. The
pole grip 1 comprises a grip body 3, which is usually produced from
a plastic material by injection molding. As seen from beneath, the
grip body 3 has a recess or a cavity 5 into which the pole, which
is formed, for example, from an aluminum shaft or a carbon-fiber or
glass-fiber shaft, can be pushed and fastened therein.
[0047] At its top end, the pole grip 1 has a recess 4 which is
designed from the hand side 43, as it were, as a blind hole. An
arresting block 6 is provided in this recess 4, which typically has
a height in the range of 10-30 mm and a width in the range of 3-20
mm. This arresting block 6 is guided in a displaceable manner in
the recess 4, and is braced in the direction of the opening of the
recess 4 via a spring 7. The spring 7 is a helical spring which is
guided, at one end, in the recess, in a stop bore 8 which is
configured as a cylindrical blind hole, and, at the other end, on a
guide peg 19 on the arresting block 6.
[0048] The recess 4 additionally has two through-slots 17 which
lead laterally out of the grip body 3. The arresting block 6 for
its part, in these regions, has bores in which a respective
actuating button 9 can be fastened on each side. The actuating
button 9 has in each case a crosspiece 20 directed toward the
arresting block 6 and, when the arresting block 6 is pushed in, it
is fastened in the arresting block 6 from the outside through the
abovementioned lateral slots 17, for which purpose a screw or
fastening pin 21 can be used in each case. This means that the
actuating button 9 can be displaced from the outside via
manipulations of the actuating buttons, this being such that, in
the normal position, the arresting block 6 is located to the
maximum possible extent in the direction of the hand side as a
result of the force of the spring 7, this maximum position
preferably being determined by the hand-side end of the slot 17.
The arresting block 6 can be pushed into the recess 4, counter to
the force of the spring, from the outside, this releasing the
arresting mechanism for the hand-retaining device.
[0049] A hook-like device ensures that the hand-retaining device is
actually secured on such a pole grip. This hook-like device
comprises a retaining peg 14 which is arranged on the hand side.
The retaining peg 14 is offset slightly in the direction of the
hand from the actual pole grip, a slot 67 which typically has a
depth of at least 10 mm being formed therebetween.
[0050] For easier assembly, the retaining peg 14 is connected to a
fastening plate 16 or formed integrally therewith. The fastening
plate 16 is located beneath the retaining peg 14 and can be
inserted in a recess provided for this purpose in the pole grip 3,
and fastened therein. This modular construction is preferred since
it is thus possible for the retaining peg 14, which is naturally
arranged in front of the recess 4, to be placed in position once
the elements which have to be arranged in the recess 4 have been
inserted into the recess 4.
[0051] The arresting block 6, for its part, likewise has a recess
24, which is bounded laterally and at the bottom but is open at the
top. The safety-activation element 12 is mounted in a movable
manner in the recess 24. For this purpose, the safety-activation
element 12 is mounted in the arresting block 6 such that it can be
rotated by way of an axial pin 22. This rotatable mounting, in
turn, is counter to a spring force, a leg spring 10 being provided
in this case. This leg spring, on the one hand, rests on the base
of the recess 24 and, on the other hand, rests on the rear side of
the safety-activation element 12. The spring force thus retains the
safety-activation element 12 in its closed position, that is to say
in that position in which the restraining nose 11 of the
safety-activation element 12, together with the retaining peg 14,
defines a closed-off region 15, in which the loop of the
hand-retaining device ends up located. It is also possible, instead
of the leg spring 10, to use a helical spring or an elastomer
spring or the like, or combinations of such resilient elements,
which is then for example in operative connection with the rear
wall of the recess 24. Use of a helical spring may be advantageous,
in particular, at low temperatures and, moreover, allows the
restraining force of the nose 11 to be adjusted. The
safety-activation element 12 may have in the downward direction, as
can be seen in FIGS. 1c) and f) in particular, a notch, in order
that the cable can be arrested to better effect in the region
15.
[0052] As has already been mentioned, the hand-retaining device has
a loop 33, which is guided over the retaining peg 14. If the loop
33 is guided over the retaining peg from above and pulled downward,
then the entire arresting block 6 is displaced into the recess 4
because, in the case of pressure being exerted from top to bottom,
the oblique top flank of the safety-activation element 12 pushes
the arresting block 6 rearward, counter to the spring force, and
the gap between the retaining peg and grip body is released. Once
the loop has reached the region 15, the entire arresting block
springs back again toward the retaining peg 14, as a result of the
spring force of the spring 7, and the region 15 is closed. The
hand-retaining device is thus automatically fastened/latched in on
the grip body without any further manipulations being
necessary.
[0053] If the loop of the hand-retaining device is to be removed
again from the slot between the retaining peg and grip body, then
the entire arresting block 6 can be displaced upward, counter to
the spring force, via the actuating buttons 9, in which case the
nose 11 releases the region 15.
[0054] In addition to this means of automatically fastening the
hand-retaining device on the grip body, a safety-activation
mechanism is provided. For this purpose, the safety-activation
element 12 can be opened upward counter to a spring force, this
being done with the arresting block pushed all the way up to the
retaining peg. If the loop is subjected to a pronounced force in
the upward direction (for example in the event of a fall), then the
safety-activation element 12 rotates about the axial element 13
such that the region 15 is released and thus the loop, and
correspondingly the hand-retaining device, is released from the
grip body.
[0055] As is illustrated in FIG. 1g), the safety mechanism may also
be provided on the retaining peg. For this purpose, the retaining
peg has a recess 41 in which the safety-activation element 12 is
mounted such that it can be rotated about an axial element 13. A
spring 7 is again provided, in this case a helical spring, which
defines the necessary activating force. In this case, it is
possible, for example, to adjust the restoring force of the spring
7 via a screw which can be actuated on the retaining peg from the
outside, on the hand side. The screw can be screwed in, for
example, to shorten the spring, and the restoring force of the
spring is thus increased.
[0056] FIG. 2 shows a hand-retaining device which is configured
according to the invention. The hand-retaining device is configured
as a glove 25 in FIG. 2, and this glove 25 basically has a
fastening guide such as that described in DE 19751978 C2. In
respect of the details of this fastening guide, which comprises,
inter alia, an encircling fastening device (or band strip) 31 as
well as adjusting means 32 which may be designed, for example, as a
touch-and-close fastener, reference is made to DE 19751978 C2.
[0057] Instead of the hook-like connecting element which is
portrayed in DE 19751978, however, a loop 33 is arranged in the V
region between the thumb 26 and forefinger 27 in this case. That
is, the loop 33 is disposed on a surface of the hand retaining
device, between a thumb receiving portion and finger-receiving
portion. The loop is produced from cable, for example stainless
steel, encased synthetic fibers such as Aramid, Dyneema.RTM. or the
like with a thickness of 1.5 mm, the cable being a twisted cable
which may be provided, if appropriate, with a coating made of
plastic or metal or may have a tube of brass positioned around it
or has a sheath made of, for example, thermoplastically integrally
formed or braided polymer material.
[0058] The loop 33 should be fastened on the hand-retaining device
such that the forces which occur during use of the pole are
distributed to good effect over the hand. This is ensured in the
case of a hand-retaining device according to FIG. 2. Alternative
options are illustrated in FIG. 3. In FIG. 3a), a cable 35 is
fixed, in the first instance, at one end at a fastening 36 in the
palm of the hand. It is then guided through a guide sleeve 34 to
the V between the forefinger and thumb 26. The actual loop 33 is
exposed there, as at portion 65, and the cable 35 is guided
downward, once again, through the guide 34. Provided at the bottom
end of the guide sleeve 34 are a deflecting means 37 and a
fastening 38, at which the cable 35 can be adjusted in a variable
manner (cf. arrow). The length of the loop 33 can thus be adjusted
in adaptation to the user, and the forces which occur are
distributed to good effect over the glove. It is further possible
for the cable 35 to be fully retracted, in which case there is no
loop projecting outward, as at portion 65. This is advantageous, in
particular, when the glove is not to be used in conjunction with
the pole grip. In contrast to other solutions, in which connecting
elements have to be removed from the glove, this solution is
advantageous because the connecting element, in other words the
loop, is concealed in the hand-retaining device rather than having
to be removed therefrom.
[0059] Another option is illustrated in FIG. 3b). In this case, the
cable 35 is configured as an encircling cable which is adjusted in
length at its bottom end, at a button 39. It is possible to provide
a further button 40, which is arranged further below and via which
the cable 35 can be retracted if the loop is to be concealed.
[0060] Finally, FIG. 3c) illustrates an option in which the cable
is fixed at the bottom via the means 36. The loop cannot be
adjusted in length here. In order, nevertheless, for it to be
possible for the loop to be concealed when not in use, a small
pocket is provided in the V region between the thumb and
forefinger. When not in use, the loop 33 can be pushed into this
pocket 41, which has an opening at the bottom, and it is thus kept
out of the way.
[0061] It is also possible for the hand-retaining device 25 to be
in the form of a hand strap which is worn over a glove, or over the
bare hands, and has a loop 33. If a conventional hand strap is
used, then the mechanism serves as a safety-activation means; if
use is made of a hand strap which is fastened on the hand (usually
by the hand strap being guided both over the wrist and between the
thumb and forefinger and being fastened, for example, with a
touch-and-close fastener), then the use is equivalent to the glove
solution like that indicated above. Thus, as with the glove
discussed earlier, the loop 33 is disposed on the surface of the
hand strap between a thumb receiving portion and a finger receiving
portion, as discussed in further detail below.
[0062] A further preferred embodiment is characterized in that a
hand strap 68 of the type illustrated in FIG. 8 may be integrated,
to a certain extent, in a glove, in which case the hand strap
itself with the movable loop can be used without the glove and the
glove can be used with the hand strap embedded in it. The
hand-retaining device may thus be configured as a glove in which is
arranged, in one or more corresponding recesses 66, a hand strap
68. The hand strap, as illustrated in FIG. 8, preferably has three
openings 69a, 69b and 69c and which can be fastened on the hand, or
on/in the glove, in particular preferably with the aid of a
touch-and-close fastener. A first opening 69a being provided for
the thumb, a second opening 69b being provided for the other
fingers or the back of the hand, and a third opening 69c of the
hand strap being provided for the wrist. The hand strap, in
particular preferably, is arranged in the glove such that it can be
adjusted from the outside via a touch-and-close fastener arranged
in the region of the back of the hand. The hand strap can
advantageously be removed altogether from the glove and can be used
without the glove.
[0063] A further exemplary embodiment is illustrated in FIG. 4,
although this figure illustrates a cross-country ski pole grip or a
Nordic walking pole grip rather than a downhill ski pole grip. In
this case, rather than being formed separately from the grip body
3, the hook-like device 14 forms a constituent part of the grip
body. The hook-like device is realized by a slot which is provided
in the grip body 3. Correspondingly, the recess 4, which is
provided for accommodating the arresting block 6, is made from
above. In this exemplary embodiment, then, it is additionally the
case that the arresting block 6, rather than being displaceable, is
mounted in a rotatable manner, about an axial element 44.
Correspondingly, the actuating button 9 is arranged at the top, and
tilting of the arresting block 6 results in the enclosed region 15
being released. In the exemplary embodiment according to FIG. 4,
for the purpose of bracing the arresting block 6, a leaf spring 7
is provided in a corresponding recess 46 in the arresting block 6.
A restraining nose 11 is formed integrally on the arresting block
6, this nose 11 having an undercut in the case of the exemplary
embodiment according to FIG. 4. Correspondingly, this exemplary
embodiment does not have any safety-activation means; rather, when
the loop is subjected to pronounced pulling in the upward direction
out of the slot, the loop takes a firm hold in the device.
[0064] It should be pointed out that it is also possible for the
entire top region of the pole grip 1 to be of a rotatable or
displaceable configuration, as long as the possibility of automatic
latching-in is provided. There is therefore no need to provide a
recess, as is the case in the exemplary embodiment according to
FIG. 4 (but equally also in the exemplary embodiment according to
FIG. 1); rather, it is also possible for the entire arresting block
6 to be designed as the uppermost region, or as the head, of the
pole grip and for this to be mounted either in a displaceable or
rotatable manner.
[0065] FIG. 5 illustrates other exemplary embodiments based on the
exemplary embodiment according to FIG. 4.
[0066] FIG. 5a) illustrates the option of providing the nose 11
with an upwardly directed flank. If, in the case of this exemplary
embodiment, the loop is subjected to pronounced pulling in the
upward direction out of the slot, then the arresting block 6 will
rotate, and this ensures safety activation.
[0067] A more specific safety-activation means is illustrated in
FIG. 5b). In this case, the safety-activation element 12 is
designed as a displaceable nose which is guided in a bore in the
arresting block 6 and is braced against a helical spring 49. Here,
in the case of the loop being subjected to pronounced pulling out
of the slot, the entire safety-activation element 12, on which the
nose 11 is integrally formed, is displaced into the arresting block
6 and thus releases the region 15.
[0068] An alternative safety-activation means is illustrated in
FIG. 5c). In this case, the safety-activation element 12 is mounted
such that it can be rotated about an axial element 13 and is braced
against a spring 49. Here, when a loop is subjected to pronounced
pulling out of the slot, the entire safety-activation element 12,
on which the nose 11 is integrally formed, tilts into the arresting
block 6 and releases the region 15 in the process.
[0069] A further alternative is illustrated in FIG. 5d). In this
case, the safety-activation element 12 is designed as a
leaf-spring-like element, although it may also be an elastomeric
element. This element can be moved as a whole, and the region 15 is
released by the nose 11, which is formed by this element, as a
result of the entire element 12 being deformed when a loop is
subjected to pronounced pulling out of the slot.
[0070] Another approach is used in the exemplary embodiment
according to FIG. 5e). In this case, the safety-activation means is
provided on the hook-like device 14. For this purpose, the
hook-like device 14 has an internal clearance in which, once again,
a leaf-spring-like element 12 is arranged. In the case of a
pronounced force being exerted, this element yields in relation to
the hook-like device 14 and thus likewise releases the region 15 in
the manner of a safety-activation means.
[0071] A further approach is illustrated in FIG. 5f). In this case,
the entire hook-like device 14 is mounted such that it can be
rotated about an axial element 50. If a pronounced force emanates
from the slot, then the entire hook-like device 14 rotates in the
direction of the arrow illustrated and thus releases the region 15.
The rotatable mounting of the hook-like device 14 is likewise
ensured, for example, via a helical spring, counter to an
adjustable force.
[0072] FIGS. 6 and 7 illustrate a further exemplary embodiment
according to the invention. FIG. 6 illustrates the entire pole grip
1, FIG. 6a) illustrating a view from the side, and FIG. 6b)
illustrating a view from the rear, that is to say from the hand
side (arrow 43 in FIG. 6a)). FIG. 6c) illustrates an axial section
along line B-B from FIG. 6b), and FIG. 6d) shows a view of the pole
grip from above.
[0073] The pole grip 1 for a downhill ski pole, in turn, has a grip
body 3 and a cavity 5, which serves for accommodating the pole
shaft (not illustrated).
[0074] In this case, the retaining peg 14 is formed integrally with
the grip body 3, as can be seen from FIG. 6c). It is also possible
here, however, for the retaining peg 14 to be in the form of a
separate element, in the manner of FIG. 1f) and of the elements 14
and 16 illustrated therein.
[0075] The grip body 3 has a recess 4 which is open at the top and
in which an arresting block 6 is arranged. The arresting block 6 is
illustrated in detail in FIG. 7.
[0076] On the top side, the arresting block 6 has an activating
button 61, which will be described hereinbelow. The ergonomic
shaping on the rear side of the top region of the pole grip 1 in
this case is likewise formed by the arresting block 6, since the
latter has, to the sides of the hook 14, two protrusions 59 which,
as it were, surround the retaining peg 14 in the top region.
[0077] The retaining peg 14 is thus optimally embedded in the outer
contour of the pole grip 1, as is not perceived as disturbing and
it is possible for injuries to be avoided. Nevertheless, an ideal
introduction opening remains from above for a cable loop 33, as
illustrated in FIG. 2.
[0078] The arresting block 6 contains a pin 57 which is used for
the automatic latching in, for example, of a cable loop 33. The pin
57 is arranged essentially horizontally and parallel to the
direction of the arrow 43. It is mounted in a displaceable manner
in the arresting block 6, in a recess 60 provided specifically for
this purpose, the pin 57 being braced against the retaining peg 14
via a helical spring 58. The pin 57 has a restraining nose 11,
which is preferably beveled from above and is of essentially
horizontal design in the downward direction, in which case for
example an eyelet or cable loop 33 which is introduced from above
displaces the pin 57 in the rearward direction, counter to the
stressing of the helical spring 58, and the cable loop is arrested
beneath the pin 57 in the region 15.
[0079] FIG. 7a) shows an overall view from the side of the
arresting block 6 together with the elements fastening this
arresting block 6 in the pole grip 1. FIG. 7b) shows a view from
the rear, that is to say from the direction of the arrow 43 in FIG.
6a), and FIG. 7c) shows a section along line A-A in FIG. 7b). FIG.
7d), finally, shows a view from above.
[0080] The entire arresting block 6 is retained in the recess 4,
which is open at the top, in the pole grip 1. For this purpose, the
recess 4 has a through-bore to the cavity 5. A securing pin 54 is
attached to the arresting block 6 via an axial element 56, which
projects through this through-bore into the cavity 5. On the top
side, the securing pin 54 has an eye 55, for fastening the securing
pin on the arresting block 6 in a rotatable manner by way of the
axial element 56. At its bottom end, the securing pin 54 is
provided with a thread.
[0081] The securing pin 54 or the arresting block 6 fastened
thereon is braced in the downward direction, with the aid of a stop
element 52 butting against the top of the cavity 5, by way of a
helical spring 51 which, at one end, rests from beneath on a
correspondingly provided shoulder on the stop element 52 and, at
the other end, rests from above on a washer 64, which via an
adjusting nut 53 which is screwed onto the thread of the securing
pin 54 from beneath.
[0082] This design has, inter alia, the following advantages:
[0083] First of all, the arresting block 6, which is produced as an
entire unit, is very straight-forward to assemble or install. It
can be pushed into the recess 4 in the pole grip 1 from above, in
which case the securing pin 54, which is provided on the arresting
block 6, is pushed through the through-bore between the recess 4
and the cavity 5. It is subsequently possible for, in the first
instance, the stop element 52, and then the helical spring 51, to
be pushed over the securing pin 54 in the cavity 5, from beneath,
and, finally, the washer and the adjusting nut 53 can be screwed
onto the thread of the securing pin 54. The resiliently elastic
securing force in the downward direction to which the arresting
block 6 is subjected via the helical spring 51 can be adjusted by
the adjusting nut 53 being screwed upward to a greater or lesser
extent or by the installation of different springs with a different
spring constant or by virtue of the prestressing being changed by
spacers. Finally, a rotary axial element 44 can be pushed in
laterally through the bore 45 of the grip body, or through the bore
48 of the arresting block 6, as a result of which the arresting
block 6 is then mounted in the recess 4 such that it can be rotated
about the rotary axial element 44. [0084] Secondly, this design
provides for adjustable emergency activation of the entire
arresting block 6. This is because, if the restraining nose 11 is
subjected to excessive force from beneath by a cable loop 33 or an
eyelet (for example in the event of a fall), then the entire
arresting block 6 rotates about the rotary axial element 44, for
example in the counterclockwise direction in FIG. 6c) and in FIG.
7c). This takes place until the region 15 is released and the cable
loop 33 or the eyelet is released from the hook. This design then
has the advantage, inter alia, that the activating force can be
adjusted very straightforwardly by, for example, the pole shaft
being removed from the cavity 5 and the adjusting nut 53 being
adjusted from beneath, in accordance with requirements, by a
corresponding tool. It is also conceivable for the spring to be
adjusted via an adjusting device which is incorporated in, or
beneath, the grip region and is, for example, in the form of a
partially exposed knurled nut, in which case there is no need for
the grip to be dismantled in order for the activating force to be
changed. The use of a helical spring 51 also ensures this safety
activation under a wide range of different temperature conditions
and, moreover, the helical spring 51 is concealed to such good
effect in the interior of the pole grip 1 that it is possible to
avoid soiling, icing-up or the like.
[0085] If the eyelet or cable loop pushed over the retaining peg 14
is to be released from the region 15 under normal conditions, then
an activating button 61 is provided, for this purpose, on the top
side of the arresting block 6. A rotary axial element 62 is
arranged horizontally, and transversely to the direction of the pin
57, in the arresting block 6. The element which forms the
activating button 61 is mounted within the arresting block 6 such
that it can be tilted about this axial element (in the clockwise
direction in FIG. 6c)). Furthermore, a guide pin 63 is arranged in
the pin 57, likewise horizontally and transversely to the pin 57.
This guide pin 63 is likewise mounted in the element which forms
the activating button 61.
[0086] If the activating button 61, which is formed integrally with
the lateral protrusions 59, is pushed downward either in the region
61 or at the protrusions 59, for example by the thumb of the hand
which is gripping the pole, then the element which forms the
activating button tilts slightly downward as a whole and thus, upon
rotation about the rotary axial element 62, pushes the pin 57
inward via the guide pin 63, counter to the force of the helical
spring 58, consequently releases the region 15 in the upward
direction and thus also releases a loop which has been arrested in
this region.
[0087] This design is highly advantageous insofar as the
protrusions 59 are ideally positioned for the desired activation,
but undesired activation can nevertheless be fully avoided.
