Description
CROSS-REFERENCE TO RELATED APPLICATION
[0001] This application is based upon French Patent Application No.
00 15372, filed Nov. 24, 2000, 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 an assembly for retaining a
boot on a sports apparatus, such as a gliding board.
[0004] 2. Description of Background and Relevant Information
[0005] Assemblies of the aforementioned type are used in fields
such as skiing, snowboarding, water skiing, snowshoeing,
skateboarding, and the like.
[0006] Generally speaking, a retaining assembly includes a base
provided to receive the foot of a user or the sole of a boot. A
disk serves to retain the base on the apparatus, the disk itself
being retained on the apparatus by screws that extend through
elongated holes of the disk that extend into its thickness.
[0007] To mount the retaining assembly on the apparatus, or to
adjust the position of the assembly on the apparatus, the user
generally must screw the screws successively into bushings, which
are themselves anchored in the apparatus.
[0008] The positioning of the screws in the bushings, through the
elongated holes of the disk, takes times and requires a certain
amount of skill. For each of the screws, it is necessary to
successively locate the bushing, position the screws, and then turn
the screw until it is seated.
[0009] The mounting and adjusting operations are relatively
time-consuming and tedious.
SUMMARY OF THE INVENTION
[0010] An object of the invention in particular is to facilitate
the positioning of an assembly for retaining a boot on a gliding
board.
[0011] To this end, the invention proposes an assembly for
retaining a boot on a sports apparatus, the assembly including a
base provided to receive the sole of the boot, a disk provided to
retain the base on the apparatus, the disk having at least two
elongated holes parallel, or substantially parallel to one another,
which extend through the disk in its thickness, and at least two
screws each extending through an elongated hole.
[0012] The retaining assembly according to the invention further
includes a plate that is parallel, or substantially parallel, to
the disk, the plate sliding along the length of the elongated
holes, at least two holes extending through the plate in its
thickness, each screw extending through a hole of the plate, and
retaining means retaining the screws on the plate.
[0013] Thus, when the user displaces a screw along an elongated
hole, in order to position the screw in front of a bushing of the
board, all of the screws are displaced simultaneously and are each
positioned in front of a bushing of the board.
[0014] The user positions all of the screws in a single
manipulation. As a result, the mounting and adjusting operations
are less time-consuming and simpler. The positioning of the
assembly for retaining a boot on the board is easier.

DETAILED DESCRIPTION OF THE INVENTION
[0023] The first example, or embodiment, of the invention is
described hereinafter with reference to FIGS. 1-4.
[0024] As seen in FIG. 1, a retaining assembly 1 makes it possible
to retain a boot, not shown, on a sports apparatus 2. The latter is
shown in the form of a board. The board can be a snowboard, for
example.
[0025] In a known fashion, the retaining assembly 1 includes a base
3 that extends along a longitudinal direction L, between a rear end
4 and a front end 5. An upper surface 6 of the base 3 is provided
to receive the sole of the boot. A lower surface 7 of the base 3 is
provided to be above the board 2. The upper surface 6 is
transversely demarcated, at least in part, by lateral flanges 8, 9.
An arch 10 connects the flanges 8, 9 to one another toward the rear
end 4.
[0026] The base 3, flanges 8, 9, and arch 10 are shown in the form
of a unitary piece made, for example, of a plastic material.
However, one could provide for the flanges 8, 9 and the arch 10 to
be attached on the base by any means, such as adhesive(s), screws,
and/or the like.
[0027] Although not necessary according to the invention, pads 11,
12, 13 are arranged so as to project with respect to the upper
surface 6 of the base 3. These pads are made preferably of a
flexible plastic material, such as silicone, polyurethane, or the
like, for absorbing impacts.
[0028] According to the embodiment shown, the boot is retained on
the base 3 by means shown in the form of straps 14, 15. These
straps can be opened, closed, tightened or loosened by the user,
using any means known to a person with ordinary skill in the
art.
[0029] The means for retaining the boot could be different. For
example, one can provide one or several latches fixed to the base
and an anchoring member fixed to the boot, the latter being
removably housed in the latch.
[0030] A rear support element 16 is arranged in the area of the
arch 10 so that the user can press toward the rear of the assembly
1 with the lower leg. The support element 16 is journalled along a
substantially transverse axis, so that it can be folded forwardly
for storage.
[0031] A disk 20 is provided to retain the assembly 1 on the board
2.
[0032] To this end, the disk 20 is obtained in the form of a lower
cylinder 21 overlaid by a shoulder 22. The disk is nested, from the
upper surface 6, in a circular opening 23 of the base 3. The outer
shape of the disk 20 and the shape of the circular opening 23 are
complementary, the opening 23 being demarcated in its lower portion
by a shoulder 24.
[0033] The shoulders 22, 24 preferably have a parallelepipedic
cross section, but they could have another shape such as that of a
truncated cone, a rounded shape, or the like.
[0034] Preferably, the shoulders 22, 24, respectively, have
peripheral toothings that are nested in one another in order to
obtain a rotational obstacle connection of the base 3 with respect
to the disk 20. Alternatively, a frictional connection could be
provided, in which toothings are omitted.
[0035] The disk 20 itself is detachably affixed to the board 2 by a
means shown in the form of four screws 30, 31, 32, 33 that extend
through four elongated holes 34, 35, 36, 37, respectively, of the
disk 20 in its thickness.
[0036] The four screws are screwed into the board 2, for example,
into threaded bushes, or bushings, 38, 39, 40, 41, which are
themselves anchored in the board.
[0037] The four bushes are each located at the top of a square,
having sides 40 millimeters (mm) long, for example, or
approximately 40 mm long.
[0038] So that the disk 20 can be displaced translationally with
respect to the board 2, the four elongated holes 34, 35, 36, 37 are
parallel to one another, aligned in pairs, and across from one
another in pairs.
[0039] All of the elongated holes preferably have the same length,
which can be between about 20 mm and 30 mm.
[0040] A different number of screws and elongated holes could be
provided. For example, three screws could each be arranged at the
vertex of an equilateral triangle. In this case, the disk would
have three elongated holes and the bushes would be arranged in
triangle.
[0041] According to the invention, a plate 50 is arranged so as to
be parallel to the disk 20, such that it can slide along the length
of the elongated holes.
[0042] As shown in FIG. 3, the plate 50 is housed in a cavity 58
provided in the lower portion of the disk 20. The cavity 58 has a
substantially flat bottom 59 that is parallel to the base 60 of the
disk 20. Preferably, the contour of the cavity 58 has a
parallelepipedic shape whose short side is substantially equal to
the side of the plate 50, and whose long side is greater than the
side of the plate 50 by a length at least equal to the length of
the elongated holes, and oriented along the length of the elongated
holes 34, 35, 36, 37.
[0043] The plate 50 is provided to slide in the cavity 58 in the
manner of a drawer.
[0044] The plate 50 is shown in the form of a square sheet, bored
with four holes 51, 52, 53, 54, spread to the four corners of a
square. The square spreading of the holes is the same as the square
spreading of the bushes 38, 39, 40, 41 of the board.
[0045] Other shapes for the plate could be used, such as that of a
cross, disk, frame, or the like, for a same distribution of the
holes.
[0046] The plate 50 can be made of metal or plastic, for example,
and can have a thickness comprised preferably between 0.1 mm and
1.0 mm, or approximately within the range of 0.1 mm and 1.0 mm.
[0047] As can be understood with reference to FIG. 2, the plate 50
and screws 30, 31, 32, 33 are configured so that the plate 50
retains the screws on the disk 20.
[0048] For example, the screw 30 has a head 55 extended downwardly
by a smooth portion 56, then a threaded portion 57. The diameter of
the smooth portion 56 is smaller than the diameter of the hole 51
of the plate 50 through which it passes.
[0049] The diameter of the hole 51 is substantially equal to the
diameter of the threaded portion 57.
[0050] It is thus possible to mount the screw 30 on the plate 50 by
forcibly screwing it until the smooth portion 56 reaches the hole
51. After screwing, the threaded portion 57 is located on the other
side of the plate 50 with respect to the head 55 and with respect
to the disk 20.
[0051] The other screws 31, 32, 33 are retained on the plate 50 in
the same manner.
[0052] Other means could be provided to maintain the screws on the
plate 50, such as a radial pin extending through the screw
body.
[0053] As seen in FIG. 4, in the area of the elongated holes 34,
35, the screws 30, 31 extend through both the elongated holes of
the disk 20 and the holes 51, 52 of the plate 50, respectively, so
as to be screwed into the bushes 38, 39 of the board 2.
[0054] Thus, when mounting the retaining assembly 1 on the board 2,
the screws are associated with the disk 20, and the positioning of
one screw above a bush simultaneously brings about the positioning
of the other screws, each above its respective bush. The plate 50
synchronizes the translational displacements of the screws in the
elongated holes.
[0055] As a result, the mounting of the assembly 1 on the board 2
is advantageously quicker.
[0056] If the number of the screws had been different, the number
of holes in the plate 50 would also have been different. In the
case where three screws are in a delta-arrangement, three holes of
the plate are in a delta-arrangement.
[0057] The second example of embodiment of the invention is
presented hereinafter with reference to FIGS. 5 and 6. For reasons
of convenience, only the portions that are necessary for
understanding are described.
[0058] A retaining assembly, not shown, is detachably affixed to a
board, not shown, by a disk 70.
[0059] In a known manner, the disk 70 preferably has a lower
cylinder 71 overlaid by a shoulder 72. The disk is provided to be
nested in the base of the retaining assembly. Four screws 73, 74,
75, 76 retain the disk 70 on the board and, to this end, extend
through elongated holes 77, 78, 79, 80.
[0060] Once again, a different arrangement and/or a different
number of elongated holes and screws could be provided.
[0061] According to the invention, a plate 90 is arranged so as to
be parallel to the disk 70 and above the latter, so that it can
slide along the length of the oblong holes 77, 78, 79, 80.
[0062] The plate 90 is shown in the form of a square sheet, bored
with four holes 91, 92, 93, 94 spread to the four corners of a
square. Here again, other forms for the plate could be used.
[0063] The plate 90 is housed in a cavity 95 provided in the upper
portion of the disk 70. The cavity 95 has a substantially flat
bottom 96 that is parallel to the upper surface 97 of the disk
70.
[0064] Preferably, the contour of the cavity 95 has a
parallelepipedic shape. The plate 90 can slide in the cavity 95 in
the manner of a drawer.
[0065] To retain the disk 70 on the board, the screws 73, 74, 75,
76 extend through the holes 91, 92, 93, 94 of the plate 90 and the
elongated holes 77, 78, 79, 80 of the disk, respectively.
[0066] Here again, the plate 90 synchronizes the displacement of
the screws along the elongated holes.
[0067] Preferably, retaining means are provided so that each screw
remains naturally in a hole of the plate 90. These means are
described for the screw 73, for example, by means of FIG. 6.
[0068] The screw 73 successively has a head 100, a smooth portion
101, and a threaded portion 102. The diameter of the smooth portion
101 is smaller than the diameter of the lower portion 103 of the
hole 91 of the plate 90 in which it passes.
[0069] The diameter of the portion 103 of the hole 91 is
substantially equal to the diameter of the threaded portion
102.
[0070] It is thus possible to mount the screw 73 on the pate 90 by
forcibly screwing it into the hole. After screwing, the threaded
portion 102 is located on the other side of the plate 90 with
respect to the head 100. The other screws 74, 75, 76 are retained
on the plate 90 in the same manner.
[0071] The plate 90 has four bosses, such as the boss 104 for the
screw 73 on the lower surface 105 of the plate. This makes it
possible to house the head of each screw in a cavity on the side of
the upper surface 106 of the plate.
[0072] Here again, other means could be provided to maintain the
screws on the plate 90.
[0073] The third example of embodiment of the invention is
presented hereinafter by means of FIG. 7. For reasons of
convenience, only the portions necessary for understanding are
described.
[0074] This example could be the first or the second, for which the
plate has been modified with respect to its structure. The plate,
designated by the reference numeral 120, still has holes 121, 122,
123, 124 for the passage of the screws. Each hole communicates with
the periphery of the plate via a slit 125, 126, 127, 128. The plate
120 can be made of a plastic or metallic material whose thickness
can be comprised between 0.5 mm and 3.0 mm, or approximately
therebetween. Each slit enables a deformation of the plate in the
area of the hole to which it is connected. It is thus possible to
allow a screw to pass by applying an axial force, without rotating
it.
[0075] Generally speaking, the invention is embodied by all the
means and from all the materials known to a person with ordinary
skill in the art.
[0076] The invention is not limited to the particularly described
and illustrated examples heretofore presented, and includes all of
the technical equivalents that fall within the scope of the claims
that follow.
[0077] In particular, the synchronizing plate does not need to be
housed in a cavity of the disk.
[0078] The synchronizing plate could be made of a plastic material,
with deformable bores in the area of the holes for the passage of
the screws.
[0079] Furthermore, one could provide to arrange elongated holes
directly in the base, without using a disk.
