Description
CROSS-REFERENCE TO RELATED APPLICATION
[0001] This application is based upon French Patent Application No.
01 01603, filed Feb. 2, 2001, the disclosure of which is hereby
incorporated by reference thereto in its entirety, and the priority
of which is hereby claimed under 35 U.S.C. .sctn.119.
BACKGROUND OF THE INVENTION
[0002] 1. Field of the Invention
[0003] The present invention relates to a device for a quick
binding of a boot on a moving apparatus. Although not necessarily,
the invention relates to a boot with a flexible upper provided with
a flexible sole according to a boot standard adapted to a specific
sporting activity, such as cross-country skiing and/or nordic
skiing, or even snowshoeing, requiring the sole and the boot to
bend.
[0004] Whatever the case may be, the boot is of the type including,
at the front, a transverse connection member adapted to cooperate
with a retaining mechanism affixed to a support plate of the
apparatus,
[0005] 2. Description of Background and Relevant Information
[0006] To ensure that the boot is properly held, especially in the
case of a flexible boot for a sporting activity which prevents the
flexibility of its sole, it is known to arrange, on the plate,
means for retaining the heel that are affixed to a slide mounted
freely in a rectilinear guide of the plate so that they can be
adjusted into a position relative to the front of the boot. Such a
construction is described, for example, in the commonly owned
French Patent Publication No. 2 804 613.
[0007] This has the advantage of making it possible to adjust the
device between two extreme positions corresponding to the smallest
size and to the largest size of the boot to be mounted on the
retaining device.
[0008] Nevertheless, a disadvantage of this known device lies in
that the slide is connected to the boot, at its rear portion, by
means of a connecting member that is constituted by a strap that
locks on the upper of the boot.
[0009] Therefore, the user is forced to bend down in order to
manually lock the strap.
[0010] Moreover, in this type of device, the transverse connection
rod cooperates with a hook of the plate that is directed downward,
which requires from the user to substantially bend the boot
forward, in a practically perpendicular manner, so as to hook the
curved portion by means of the front transverse connection rod
before folding back the boot toward the plate for strapping,
[0011] This maneuver can prove particularly uncomfortable under
certain conditions, especially during the removal of the boot.
SUMMARY OF THE INVENTION
[0012] An object of the present invention is to overcome the
various aforementioned disadvantages of the known devices and, to
this end, the invention relates to a device for a quick binding of
a boot on a moving apparatus, which occurs by means of a front
transverse connection member of the boot adapted to cooperate with
corresponding retaining mechanism affixed to a front zone of the
support plate of the apparatus, on the one hand, and by means of a
retention mechanism for the heel affixed to a slide that is mounted
freely in a rectilinear guide of the plate so that they can be
adjusted into a position relative to the front of the boot, on the
other hand. The mechanism for retaining the front and the rear of
the boot on the plate are constituted by a positive locking
arrangement with automatic snap engagement, which can be actuated
against an elastic return mechanism, without manual intervention,
by mere pressure of the boot on the front and then on the rear
along substantially vertical downward movements, and consequently
in a substantially horizontal position of the boot,
[0013] The present invention also relates to the characteristics
which will become apparent from the description that follows, and
which must be considered separately or according to all of their
possible technical combinations,

DETAILED DESCRIPTION OF THE INVENTION
[0021] The quick binding device, generally designated by the
reference numeral 1 in FIGS. 1-6, is adapted to be inserted between
a boot 2 and a moving apparatus 3. As shown in these figures, this
binding occurs by means of a front transverse connection member 4,
shown as a pin or rod, located in the area of the sole 5 of the
boot 2.
[0022] The front transverse connection member 4 is adapted to
cooperate with corresponding retaining mechanism 6 affixed to a
front zone of the support plate 7 of the apparatus 3. Furthermore,
generally speaking, the binding is also carried out by a mechanism
8 for retaining the heel zone 9 of the boot 2.
[0023] The retaining mechanism 8 is affixed to a slide 10 mounted
freely in a rectilinear guide 11 of the plate 7 so that it can be
adjusted into a position relative to the front of the boot 2.
[0024] According to the general concept of the invention, the
retention mechanism 6 for retaining the front A and retention
mechanism 8 for retaining the rear B of the boot 2 on the plate 7
are constituted by positive locking members 12, 40 with automatic
snap engagement, which can be actuated without manual intervention
by mere pressure of the boot 2 on the front A, then on the rear B
along substantially vertical downward movements F1, F2, and
consequently in a substantially horizontal position of the boot
2.
[0025] According to a first embodiment shown in FIGS. 1-6, the
locking members 12, 40, located at the front and rear,
respectively, of the plate 7, are elastically returned by a common
mechanism 20 connected directly and freely to each of the members
12, 40.
[0026] According to this same example, the front member 12 for
automatic locking of the boot 2 includes a fixed jaw 13 affixed to
the front end of the plate 7 and defining, at its upper portion, a
first groove portion 14 open upwardly, and by a movable jaw or
rocker 15, journalled by an axle 16 directly on the fixed jaw 13 or
the plate 7 and defining, at a lower inner portion, a second groove
portion 17 open downwardly and complementary to the first groove
portion 14 so as to define a housing whose cross-section
corresponds to that of the transverse connection member 4 adapted
to be housed therein after rockingly pushing back the movable jaw
or rocker 15, at its free upper portion 15a opposite its journal
axle 16, which movable jaw or rocker is affixed to the elastic
return mechanism 20 shared with the member 40 for locking the rear
of the boot 2, whose base forms a slide 10 mounted freely in the
rectilinear guide 11.
[0027] According to this same example, the rear member 40 for
automatic locking of the boot 2 is constituted by a rigid front
spoiler 23 oriented downwardly and forwardly, projectingly raised
on the plate 7 and movably affixed to the slide 10 adapted to slide
freely in the rectilinear guide 11 of the plate 7 along a rear
direction P3 until snap engagement of the front spoiler 23 on a
portion of the heel zone 9 of the boot 2 forming an edge 24,
occurring under the action of the common elastic return member 20
along a front direction F4.
[0028] The functioning of this device is as follows:
[0029] The boot is inserted by presenting the boot 2 in a
substantially horizontal plane above the quick binding device 1 and
lowering the boot in the direction of the arrows F1, F2 (FIG.
2)
[0030] The connection member 4 of the boot 2 is presented on the
front locking member 12, causing the rocker 15 to pivot about the
axle 16 along a direction F5, and rocking the heel 9 in the
direction F6 toward the rear locking member 40 (FIG. 3).
[0031] The front connection member 4 is engaged with locking member
12, by snap-engagement and elastic return of the rocker 15 in the
direction F7 (FIG. 4).
[0032] The edge 24 is engaged with the heel 9 of the boot 2, by
snap-engagement, in the front spoiler 23 of the rear locking member
40 in the direction F2 due to the sliding along the direction F3,
then along the direction F4 of the member 40 (FIG. 4).
[0033] The boot is removed by unlocking of the heel 9 by the action
of the rear locking member 40 in the direction F3 and upward
rocking in the direction F8 simultaneously causing a rocking
movement in the direction 15 of the front rocker 15 by support of
the front of the boot during forward rotation, until disengagement
of its axle 4 in the direction F9 (FIGS. 5 and 6).
[0034] According to the second embodiment, the front member 12A for
automatic locking of the boot 2, particularly shown in FIGS, 7, 8,
and 9, is constituted by a fixed jaw 13A affixed to the front end
of the plate 7A and defining, at its upper portion, a first groove
portion 14a open upwardly, and by a movable jaw or rocker 15A
journalled 16A at the end of the plate 7A in the vicinity of the
fixed jaw 13A and defining, at an upper inner portion, a second
groove portion 17A open downwardly and complementary to the first
14A so as to define a cross-section corresponding to that of the
transverse connection member 4 adapted to be housed therein after
pushing back the movable jaw 15A against an elastic return member
20A that is specific thereto.
[0035] Advantageously, the fixed jaw is made as a single piece with
the plate 3, i.e., the fixed jaw and plate are made unitary, during
a common molding operation of a plastic material.
[0036] According to an improvement to the aforementioned feature of
the invention, the groove portion 14A of the fixed jaw 13A and the
complementary groove portion 17A of the movable jaw 15A have outer
engagement ramps 18 and 19 defining therebetween a V in which the
transverse rod/pin 4 is positioned prior to its snap
engagement.
[0037] Furthermore, the rocker 15S has a nose 15a directed
forwardly in a direction opposite that of the energy lug 20A in
relation to the journal axle 16a, so as to enable its rocking about
this axis thereof during an unlocking maneuver.
[0038] To facilitate the unlocking, and consequently the boot
removal, an abutment 22 is made on the upper portion of the rocker
15A, which abutment is biased during this operation by the front
portion A of the boot 2.
[0039] With respect to the rear member 40A for automatic locking of
the boot 2, the latter is constituted by a rigid front spoiler 23A
oriented downwardly and forwardly, projectingly raised on the plate
7A and movably affixed to the slide 10A adapted to slide freely in
the rectilinear guide 11A of the plate 7A along a rear direction P3
until snap engagement of the front spoiler 23A on a portion of the
heel 9 of the boot 2 forming an edge 24A, occurring in a front
direction P4 under the action of an elastic return member 25 which
is specific thereto and distinct from the elastic return member 20A
of the front locking member 12A.
[0040] According to this same embodiment, the slide 10A is
constituted of an inner part or strip 26 with a width corresponding
substantially to a lower inner groove 27A of the plate 7A forming
the rectilinear guide 11, on the one hand, and of an outer part or
back 28 perpendicularly extending the front spoiler 23A forwardly
and taking support on the upper plane 29 of the plate 7A, the strip
26 and back 28 constituting the slide 10A being joined together by
an assembly mechanism 30.
[0041] According to a particular characteristic of the front
spoiler 23A, the latter has on its upper portion a boot insertion
slope 31 directed forward and downward.
[0042] Furthermore, the front spoiler 23A is affixed to the outer
upper part or back 28 of the slide 10A by means of a perpendicular
extension 32 of the latter, on which the front spoiler 23A is fixed
by an assembly mechanism 33.
[0043] As seen particularly well in FIG. 8, the front spoiler 23A
and extension 32 of the back 28 of the slide 10A on which it is
fixed form an interface including complementary teeth 34 enabling a
height adjustment, so as to render the rear locking member 8A
adaptable to any boot height.
[0044] According to another characteristic of the invention, the
elastic member 25 for returning the slide 10A and the front spoiler
23A, which is affixed thereto, is constituted by a rubber band,
perforated along its entire length with successive adjusting holes
35, one end hole of which cooperates with a pin 36 obtained beneath
the lower surface of the back 28 of the side 10A, and one of the
other holes of which, selected as a function of the length of the
boot 2 and of the desired return force F4, cooperates with a fixed
pin 37 made on the upper surface 29 of the plate 7A.
[0045] Preferably, the pin 36 for fastening the end of the rubber
band 25, positioned beneath the back 28 of the slide 10A, is
arranged in longitudinal alignment with another blind and dreaded
pin 38, also positioned beneath the lower surface of the back 28 of
the slide 10A, the latter being adapted to the fixing of the strip
26 of the slide 10A, so that the two pins 36 and 37 can constitute
guides of the slide 10A by displacement in a longitudinal slot 39
of the plate 7A through which they extend,
