Description
[0001] The invention relates to a piece of sports apparatus that is
particularly suitable for muscle exercises, a use of said piece of
sports apparatus as well as a method for muscle exercises using
said piece of sports apparatus.
[0002] A selective muscle re-education always requires an effective
stamina training of the musculature and is effected by the movement
of the musculature. At that, muscle reeducation requires exertion
of a certain force. The forces generated by the muscles are
transmitted to objects, preferably simulators, and must be absorbed
in these simulators and braced with counteracting forces. In
competitive sport, here use is made of impact instruments, such as
sledgehammers. With these hammers objects are hit what would lead
to deformations and destructions. In order to escape this
circumstance up to the destruction use is made of bodies capable of
absorbing forces and converting kinetic energy with elasticity and
friction into heat, so that no impairments or destructions at the
simulators occur. In this way, training can be carried out in a
narrowly defined room or area. Impact noises are generated only to
small extent by the elastic bodies, preferably parts of gum, in
particular even discarded tires, in a cost effective manner.
[0003] Success of stamina training requires precise adjustment of
the employed pieces of sports apparatus to the individual
characteristics of the person exercising. At the beginning of
stamina training the forces that can be produced by the exercising
person with its muscles are relatively small. Typically that's why
stamina training is started with pieces of sports apparatus that
require a low input of force, wherein during the training the input
of force is supposed to be enhanced. For that, either another piece
of sports apparatus must be used or the piece of sports apparatus
has to be adjusted to the changing characteristics of the person
exercising. However, not every piece of sports apparatus can be
adjusted. The sledgehammers known from the prior art do not allow a
modification. Additional weights cannot be attached to the
sledgehammer with sufficient reliability with respect to the radial
forces acting in training. Thus, use of another sledgehammer is
required, which however is associated with additional costs.
[0004] It is an object of the invention to eliminate the
disadvantages of the prior art. More specifically, there is
provided a piece of sports apparatus that is particularly suitable
for muscle exercises and can be adjusted to the characteristics of
the user.
[0005] This object is solved by the features of claims 1, 10, and
11. Practical embodiments of the invention result from the features
of the dependent claims.
[0006] According to the invention there is provided a piece of
sports apparatus comprising a hammer with a hammer head wherein a
cavity for receiving a weighting element is formed and a lockable
aperture by means of which the weighting element can be introduced
into the cavity and taken out of the cavity, wherein the weighting
element is fixed in the cavity if the aperture is closed.
[0007] If the cavity is closed the weighting element is fixed
immovably in the cavity. If the cavity is open, then the weighting
element can be taken out of the cavity or introduced into the
cavity. Preferably, the weighting element is formed such that it
can be inserted into the cavity accurately fitting. Preferably, the
outer shape of the weighting element corresponds to the shape of
the cavity, so that after closure of the cavity the weighting
element is fixed form-closed therein.
[0008] Preferably, the geometric center of the cavity and the
geometric center of the hammer head lie on the same point. With
respect to the geometry of the hammer head the cavity should be
formed centrally in the hammer head. Preferably, the cavity is
equally spaced from all outsides of the hammer head. Preferably,
the center of gravity of the hammer head lies in its geometric
center.
[0009] In a preferred embodiment, the piece of sports apparatus
according to the invention comprises several weighting elements
with different weights. If the piece of sports apparatus according
to the invention comprises several weighting elements, then the
weighting elements form a set of weighting elements. There can only
be one weighting element present in the cavity of the hammer head.
This weighting element is chosen from the set of weighting
elements.
[0010] Preferably, a set of weighting elements comprises a first
weighting element with a basic weight. Then, each further weighting
element of the set of weighting elements has a multiple of the
basic weight, wherein the weights of the further weighting elements
differ from each other. For example, the basic weight can be 1 lb
(approx. 0.45 kg), i.e., the first weighting element has a weight
of 1 lb. Further weighting elements can have weights of 2 lb
(approx. 0.91 kg) and 5 lb (approx. 2.27 kg), respectively.
Alternatively, weighting elements having the following weights may
be provided: 4, 6, 8, 12, 14, 16, 18 and 20 lb (1.81, 2.72, 3.63,
5.44, 6.35, 7.26, 8.16, 9.07 kg). In a further alternative
weighting elements are provided the weight of which is by 5 lb
(2.27 kg) higher than the weight of the next lighter weighting
element. The lightest weighting element has a basic weight and in
this case, weighs for example 5 lb (2.27 kg). Of course, a set of
weighting elements can also comprise weighting elements having
weights that are no multiple of the basic weight. For example,
weighting elements having a weight that is no multiple of the basic
weight can be provided.
[0011] One exemplary first set of weighting elements can comprise
weighting elements having the following weights: 2, 4, 6, 8, 10 lb
(0.91, 1.81, 2.72, 3.63, 4.54 kg). This set of weighting elements
is particularly suitable for children.
[0012] One exemplary second set of weighting elements can comprise
weighting elements having the following weights: 2, 4, 6, 8, 12,
14, 16, 18 lb (1.81, 2.72, 3.63, 5.44, 6.35, 7.26, 8.16 kg). This
set of weighting elements is particularly suitable for adults.
[0013] All weighting elements should be substantially of the same
shape in order to guarantee the interchangeability of the weighting
elements. Weighting elements of different weights may be identified
by different colors, for example yellow, red, blue, green, black
etc. Further, the weighting elements can bear a declaration of
their weight, for example as stamping, projecting relief, or label.
The weighting elements can consist of materials of different
densities.
[0014] The exchange of weighting elements allows a simple
adjustment of the piece of sports apparatus according to the
invention to changed characteristics of the user, for example to
its increased muscle strength. That's why the piece of sports
apparatus according to the invention can preferably be used for
muscle re-education training.
[0015] Preferably, the hammer head has a first head section and a
second head section that are detachable connected to each other.
Here, it may be provided that in the first head section the cavity
and the lockable aperture are formed, whereas the second head
section forms the closure for the aperture. Preferably, the first
head section can be connected to the second head section by means
of a screwed connection. For that, in the inner circumferential
surface of the first head section, adjacent to its front side
having the aperture, there can be formed a female thread into which
a male thread can engage that is formed on the head section.
[0016] The hammer head should be sized as small as possible to
avoid any risk of injury.
[0017] In addition to the hammer head the hammer comprises a hammer
handle attached to the hammer head. For that, a socket can be
provided in the hammer head wherein the end of the hammer handle is
fixed. Preferably, the socket for the hammer handle is in the
geometric center of an outer surface of the hammer head, preferably
in the outer surface with the largest area. For fixation of the
hammer handle in the socket there can be provided a screwed
connection. If the hammer head has a substantially cylindrical
shape then this outer surface is the circumferential surface of the
cylinder.
[0018] The hammer handles can be of different lengths with one
hammer handle each being fixed in the socket of the hammer head. In
this way, the length of the hammer handle of a hammer provided
according to the invention can be adapted to the needs of the user.
For this purpose, the hammer handle can detachable be attached in
the hammer head. Alternatively, the piece of sports apparatus
according to the invention can comprise several of the hammers
according to the invention with the hammers having different hammer
handle lengths. In this case, the hammer handles preferably are
permanently connected to the hammer head.
[0019] In the above-mentioned first set of weighting elements there
may be provided three hammer handles of different lengths: a first
hammer handle with a length of 24 in (approx. 61 cm) if a weighting
element having a weight of 2 or 4 lb is fitted into the hammer
head; a second hammer handle with a length of 28 in (approx. 71 cm)
if a weighting element having a weight of 6 or 8 lb is fitted into
the hammer head; and a third hammer handle with a length of 34 in
(approx. 86 cm) if a weighting element having a weight of 10 lb is
fitted into the hammer head.
[0020] In the above-mentioned set of second weighting elements
there may also be provided three hammer handles of different
lengths: a first hammer handle with a length of 24 in (approx. 61
cm) if a weighting element having a weight of 2 or 4 lb is fitted
into the hammer head; a second hammer handle with a length of 30 in
(approx. 76 cm) if a weighting element having a weight of 6 or 8 lb
is fitted into the hammer head; and a third hammer handle with a
length of 36 in (approx. 91 cm) if a weighting element having a
weight of 10. 12, 14, 16, or 18 lb is fitted into the hammer
head.
[0021] The hammer handle can be provided with a jacket made of a
damping material, such as for example gum or another elastic
material. Preferably, the jacket is located at points where the
user will typically touch the hammer handle with his hands when he
uses the piece of sports apparatus in accordance to its purpose.
Preferably, the jacket is formed at the end of the hammer handle
that is not or is not intended to be fixed in the socket of the
hammer head. It is however preferred that the entire hammer handle,
except of the section that is inserted into the socket, is jacketed
with a damping material. It is also preferred that also the outer
surfaces of the hammer head are provided with a jacket made of the
damping material, except for the socket for the hammer handle.
Here, it must be ensured that the aperture of the hammer head can
be both, opened and closed. If both the entire hammer handle and
the outer surfaces of the hammer head are provided with a jacket
made of the damping material, then after fixation of the hammer
handle in the socket of the hammer head the entire hammer is
jacketed with the damping material. The damping material shall damp
the impulse that can be applied by the hammer onto a surface.
[0022] In its outer shape the hammer according to the invention can
look like a known sledgehammer. The hammer according to the
invention can be employed as sledge hammer.
[0023] In addition to the hammer and one or more weighting elements
the piece of sports apparatus according to the invention can
further comprise an impact mat for damping or receiving the impulse
generated by the hammer. The impact mat can be a rubber mat. The
user of the piece of sports apparatus applies his hammer blows onto
the impact mat. In that occasion, the impact mat can be placed on
the floor or fixed to a wall. Depending on the expected effort of
the user it may be provided that several of the same impact mats
are superposed on each other.
[0024] The hammer, the weighting element(s) and if present the
impact mat(s) constitute the components of the piece of sports
apparatus. Here, exactly one weighting element can be present in
the hammer head. Preferably, the impact mat(s) are arranged such
that a user during the training can strike the hammer head with its
front side onto a flat side of the impact mat or, if several impact
mats are superposed on each other, onto the outer flat side of the
outer impact mat. In this context, the distance between the impact
mat(s) and the position of the user is determined by his height,
the length of the hammer handle and the way the user is swinging
the hammer. The determination of this distance can easily be done
by each user himself. The relation between the weighting elements
that are not present in the hammer head and the hammer are not
spatially defined. Preferably, they are outside the user's radius
of action during his exercises, but preferably in the same room or
in a room that is immediately adjacent to his radius of action.
[0025] According to the invention there is further provided the use
of the piece of sports apparatus according to the invention for
muscle exercises, in particular for muscle reeducation training. In
particular, the muscle exercises can be performed for
nontherapeutic purposes.
[0026] By means of the piece of sports apparatus according to the
invention the user can perform physical exercise by swinging the
hammer provided according to the invention and in doing so
repeatedly striking the hammer head onto a surface, for example the
surface of an impact mat. For these hammer blows the user needs
strength produced by his muscles and that he exerts on the surface.
The strength needed depends on the weight of the weighting element
present in the cavity of the hammer head, and on further
circumstances, for example the height of the user, the length of
the hammer handle, the grip with which the user holds the hammer,
and the movement of a hammer blow. In the following, there are
described exercises that can be performed with the piece of sports
apparatus, wherein other exercises may also be provided.
[0027] First exercise: If the hammer blows are stricken onto
substantially horizontal surfaces, for example the floor or an
impact mat lying on the floor, then the movement as core movement
includes an upswing wherein the hammer head is stricken from the
bottom to the top, and a downswing wherein the hammer head is
stricken from the top to the bottom. Here, the up and downswings
are substantially performed in a nearly vertical plane on a
circular path having a rotational axis running nearly parallel to
the horizontal surface. Here, the hammer head is stricken in a
lumberjack style over the head or at the height of the head passing
it. On the upswing, in particular the muscles of the forearms,
shoulders, the lower back, and the hamstrings are strained. On the
downswing, in particular the muscles of the forearms, latissimus
dorsi, and abdominal muscles are strained. In both cases, also
biceps and triceps are strained as supporting muscles.
Stabilization of the hammer during the hits, in particular
balancing the back stroke of a hammer blow, particularly strains
the rotator cuffs of the upper arms.
[0028] Second exercise: If the hammer blows are exerted on a
vertical surface or on a surface inclined by up to 45.degree. to
the perpendicular with the lower end of the surface preferably
being less spaced from the user of the piece of sports apparatus
according to the invention than the upper end, then, on the
upswing, the hammer head is stricken away from the surface, but
less from the bottom to the top, but in a rather horizontal plane
on a circular path the axis of which lies nearly parallel to the
vertical or inclined surface. The same also applies to the
downswing, with the difference that the hammer head is stricken
towards the surface. In these movements, the rotator cuffs of the
trunk are more strained than with hammer blows exerted on a
horizontal surface. With vertical or inclined surfaces strain of
the hip and the oblique muscles is greatly increased. Adductors and
abductors of the hip are stretched more. Moreover, the mid
trapezius muscle of the back is more stretched by performing the
hammer blows in the rather horizontal plane. If the swinging
movements are performed in a manner typical of baseball, then a
higher shoulder activity is required.
[0029] The term "rather" is intended to express that the movements
are not ideally performed in a horizontal plane or vertical plane,
but that deviations in striking the hammer head from these planes
are to be expected.
[0030] Third exercise: It is possible to perform a combination of
these movements. For example, on the upswing the hammer head may be
stricken away from the lower end of a vertical or inclined surface
to the top and back on the downswing. As a result, there is
performed a movement typical of hitting a golf ball. Here, the
rotator cuffs of the trunk are more strained than with the
movements in a vertical plane. Hips and oblique muscles are greatly
strained. Adductors and abductors of the hip are more stretched.
Moreover, the mid trapezius muscle of the back is more stretched by
performing the hammer blows in the rather horizontal plane. Most
rotator cuffs are strained.
[0031] Preferably, the exercises are united into one group. Then,
from this group one or more exercises can be chosen.
[0032] Finally, according to the invention there is provided a
method for muscle exercises using a piece of sports apparatus
according to the invention comprising the steps of: [0033] (a)
inserting a weighting element by means of the lockable aperture
into the cavity of the hammer head; [0034] (b) closing the lockable
aperture of the hammer head to fix the weighting element in the
hammer head; and [0035] (c) exerting one or more hits with the
hammer.
[0036] Preferably, in step (c) the hits are exerted on the impact
mat. It may further be provided that the choice of a weighting
element having the desired weight precedes step (a) and that
subsequent to step (c) the following steps are provided: [0037] (d)
opening the lockable aperture of the hammer head; [0038] (e)
removing the weighting element present in the cavity; [0039] (f)
choosing another weighting element the weight of which differs from
the weight of the weighting element removed in step (e) and
repeating steps (a) to (c).
[0040] Hereinafter, the invention is explained with the help of

for muscle exercises.
[0047] FIGS. 1 to 3 show an embodiment of the hammer of the piece
of sports apparatus according to the invention. The hammer 1
includes a hammer head 2 consisting of a first head section 3 and a
second head section 4. In FIGS. 1 and 3, the first head section 3
is screwed together with the second head section 4 indicated by a
separation line 5. The hammer head 2 is connected to a hammer
handle 8.
[0048] The hammer head 2 has a substantially cylindrical shape with
the edges between its front sides and its circumferential surface
being flattened.
[0049] In FIG. 2, showing the hammer head 2 in the opened state, it
can be seen that the hammer head 2 is in a cavity 6. The cavity 6
is formed in the first head section 3. The second head section 4
has been unscrewed from the first head section to open the aperture
7 by means of which a weighting element 10 can be inserted into and
removed from the cavity 6. The aperture 7 is formed in the front
side of the first head section 3 which after screwing both head
sections 3, 4 faces the second head section 4. In FIG. 3, showing
the hammer head 2 in the closed state, it can be seen that the
weighting element is fixed in the hammer head 2 such that it cannot
move there relative to the hammer head.
[0050] FIGS. 2 and 3 each are sectional views along the

jacket.
[0052] In FIGS. 3 and 4. the weighting element 10 that is immovably
fixed in the cavity 6 has a weight of "2 lb" (approx. 0.91 kg), It
is therefore labeled with the indication "2 lb". According to the
invention there may be provided further weighting elements one of
which can be present in the cavity 6 of the hammer head 2.
According to the invention there may be provided one or more impact
mats.
[0053] As shown in FIG. 5, the piece of sports apparatus according
to the invention can comprise a hammer 1, a set of weighting
elements, and an impact mat 12. The set of weighting elements
comprises several weighting elements of different weight, wherein
for simplification the representation in FIG. 5 shows only three
weighting elements: a first weighting element 10a with a weight of
1 lb; a second weighting element 10b with a weight of 2 lb, and a
third weighting element 10c with a weight of 5 lb. The hammer 1
corresponds to the hammer 1 shown in FIGS. 1 to 3. In FIG. 5, the
topside 14 of the impact mat 12 is shown. Preferably, the hits of
exercising persons are exerted on this topside.
[0054] A method for muscle exercises using the piece of sports
apparatus shown in FIG. 5 can be performed as shown in FIG. 6a.
First, the piece of sports apparatus shown in FIG. 5 is provided
101, wherein preferably still no weighting element 10 is introduced
in the hammer head of the hammer 1. If there would be already a
weighting element 10, it is removed from the hammer 1 unless it is
the weighting element 10a that is chosen by the coach or the person
exercising in the subsequent step 102 from the set of weighting
elements 13. Then, the chosen weighting element 10a in inserted
into the hammer head of the hammer 1 103. Finally, one or more hits
are exerted with the hammer 1 on the impact mats 12 104. The way
the hits are performed may be according to guidelines that describe
how to make the hit. These guidelines are referred to as exercises,
wherein various exercises can be performed with the hammer. Thus,
step 104 can comprise the individual steps shown in FIG. 6b.
[0055] In FIG. 6b it is shown how to make the choice of the
exercises. The groups of exercises from which the exercise is
chosen comprises for example the first exercise, the second
exercise, and the third exercise the course of which has been
described above. From this group, the coach or the person
exercising chooses the exercises 201, for example the first
exercise. Then, the person exercising performs this exercise for
one or two times 202. If the exercise should not be repeated any
longer, so the coach or the person exercising can choose another
exercise 203, for example the third exercise. Then, the exercise is

weighting element.
[0056] If the coach or the person exercising wishes to continue the
training with another weighting element, then another weighting
element can be chosen from the set of weighting elements 105 (for
example weighting element 10b) and after removal of the first
weighting element 10 from the hammer head of the hammer 1 can be
inserted into the hammer head 106. Finally, again one or more hits
with the hammer 1 onto the impact mat 12 can be exerted 107. The
hits may be exerted in accordance to the guidelines from the group
of exercises. Thus, step 107 can comprise the individual steps
shown in FIG. 6b.
