[0001] This invention relates to a heelplate structure particularly for ski boots.
[0002] It is known to use, for protecting the heel region of the sole of a ski boot, a heelplate
piece which is usually formed of a rubber or the like material block accommodated
in a recess defined in the bottom rear region of a boot heel.
[0003] In conformity with a currently utilized technique such a rubber heelplate would be
fastened by means of one or more screws of a non-rust material.
[0004] Thus, with such prior solutions, when the user is to replace a worn out heelplate,
he/she is required to remove the screws in order to release the heelplate for replacement
with a new one.
[0005] This operation, while being simple per se, must be carried out, however, with some
skill in order to avoid damaging the screw hole threads, since any damage would result
in an unreliable attachment of the new heelplate.
[0006] Furthermore, loosening two or more screws may be difficult where the screw heads
are worn, and even where such an operation appears to be simple to carry out, it is
inconvenient for the user.
[0007] It is the aim of this invention to obviate such prior disadvantage by providing a
heelplate structure which can be attached to a ski boot without resorting to the use
of screws or the like fasteners.
[0008] Within the above aim, it is a particular object of the invention to provide a heelplate
structure which, while including a much simplified fastening means, can give full
assurance of a firm and durable fit of the heelplate to the ski boot.
[0009] It is another object of this invention to provide a heelplate structure which is
simpler to manufacture and of moderate cost.
[0010] The above aim, as well as these and other objects such as will be apparent hereinafter,
are achieved by a heelplate structure particularly for ski boots, according to the
invention, comprising a heelplate block receivable in a recess formed in the bottom
rear region of the heel of a ski boot, characterized in that it comprises interlocking
means for removably securing said heelplate block in said recess.
[0011] Further features and advantages will be more clearly understood from the following
detailed description of a heelplate structure particularly for ski boots, as illustrated
by way of example and not of limitation in the accompanying drawing, where:
Figure 1 is a longitudinal cross-section of the heelplate according to the invention;
Figure 2 is a perspective view of the heelplate block; and
Figure 3 is a longitudinal cross-section of the heelplate according to a further embodiment
of the invention in which the male interlocking means is fitted to the ski boot.
[0012] With reference to the drawing views, a heelplate structure particularly for ski boots,
according to the invention, comprises a heelplate block, generally designated with
the reference numeral 1, which is advantageously formed from rubber or the like materials.
[0013] The heelplate block 1 is receivable, in a conventional fashion, in a recess 2 defined
in the bottom rear portion of the heel 4 of a ski boot.
[0014] A unique feature of the invention is that an interlocking means is provided for removably
securing said heelplate block 1 in the recess 2.
[0015] In a preferred embodiment, such interlocking means consists of a mushroom-shaped
element, generally designated with the reference numeral 10, including a stem 11 with
an enlarged head 12 which is formed peripherally with a conical taper 14 adapted for
insertion into a throughgoing hole 20 provided in the cited recess 2 and open to a
depression 21 within the ski boot which will receive the head 12 such that it cannot
protrude inwards and provide an abutment for engagement with the head.
[0016] In an equally useful embodiment, the mushroom-shaped element, indicated at 10', is
provided directly in the recess 2, thereby the heelplate block will be formed with
a throughgoing hole 13' through which the stem 11' can be inserted whereto an enlarged
head 12' having a frusto-conical taper 14' is attached, which head is received in
a repression 21' defined in the heelplate block 1' and forming the abutment for the
enlarged head 12'.
[0017] With the arrangement described above, the heelplate block can be pressed in place
directly without using screw fasteners.
[0018] To replace the heelplate, it will be sufficient to remove the heelplate block by
prying it out with a screwdriver or equivalent tool inserted between the recess and
heelplate block, thus practically dislodging the worn heelplate, and then insert a
new heelplate block into the same position with a pressing action.
[0019] It will be appreciated that the rubber material of the heelplate block is advantageously
more elastically deformable than the material of the heel or sole, which is advantageously
plastic material. Thereby the snapping-in action and the replacement is facilitated.
[0020] It may be appreciated from the foregoing discussion that the invention achieves its
objects, and in particular that a heelplate structure is provided which has a greatly
simplified construction and can be readily assembled without involving any complex
or troublesome operations.
[0021] In practicing the invention, any suitable material, dimension, and contingent shape,
may be used to meet individual requirements.
