Description

ONLINE ICE SKATE BOOTS
WITH FLEXIBLE SLIPPERS AND REAR CALIPER
The invention relates to an ice-skate boot or to at least two in-line rollers, that is to say aligned in the longitudinal direction of the boot-skate.

 ice skates or in-line roller skates are already known comprising a rigid rising boot and a blade or at least two rollers mounted in line under the boot. Such roller skates make it possible to carry out developments similar to those achievable with ice skates.

 The main problem which arises for the production of these skates is that of sufficient lateral support of the foot and ankle, with a low weight and an acceptable esthetics of the skate.

 Thus, we have already thought of making the boot like a simple flexible basket to give a pleasant aesthetic to the skate and a good lightness. But the support of the foot is then largely insufficient. Conversely, there are already known in-line roller skates, the boot of which is made in the manner of an alpine ski boot, that is to say essentially formed from a rigid rising shell made of synthetic material covering all foot and ankle. This gives correct support for the foot, but the aesthetics are poor and the weight of the skate or its cost are disadvantages.

 In addition, ice skates have long been fitted with rigid leather ankle boots which have better rigidity than sneakers and are lighter than rigid shell ankle boots. But the support of the foot and ankle obtained with these boots is now considered insufficient, especially for inline skates with which we perform increasingly acrobatic figures that require perfect lateral support.

In addition, the aesthetics of leather boots have gone out of fashion.

 To preserve the external appearance of a basket by improving the lateral support, it has already been thought (for example French patent 2,172,872) to provide a skate without boot with a rigid rising rod connecting the leg to the frame of the skate. But this rod affects the aesthetics of the skate, is complex and causes localized pain on the part of the leg where it is supported.

 The invention therefore aims to overcome these drawbacks and its object is to provide an ice-skate boot or, more particularly, in-line rollers ensuring improved lateral support of the foot and ankle while comprising a light boot and whose l he aesthetic is as close as possible to that of a basketball, that is to say light and sporty.

 To do this, the invention relates to an ice-skate boot or in-line roller skate comprising a blade or at least two rollers mounted under the boot characterized in that it comprises a rigid sole, a flexible boot enclosing the foot having its rear part rising at least above the ankle, and which is rigidly associated with the sole, and a rigid rear stirrup rigidly associated with the sole and extending on each side of the rear part of the bootie over most of its height to maintain the foot and prevent lateral bending of the ankle, while allowing forward and backward bending, the boot having essentially the appearance and characteristics of a basketball.

 According to the invention, the stirrup is rigidly associated with the sole and the liner and consists of a single piece comprising two lateral wings extending on each side of the rear part of the liner and a core connecting the lateral wings in their lower part. The core is interposed between the boot and the sole and the side wings are sewn to the boot. The stirrup forms a rear rising edge covering the heel.

 According to the invention, the rigid sole has rigid edges on each side and at the front of the liner.

According to the invention, the boot further comprises a front peripheral reinforcement extending along the lateral parts of the liner from the stirrup and above the front end portion of the liner.

 The liner is made of canvas or soft leather or flexible synthetic material, the sole and the stirrup are made of hard and rigid synthetic material, and the front peripheral reinforcement is made of rigid synthetic material, but less rigid than the sole and the stirrup , or in rigid leather.

The liner is not covered or made up of a closed rigid shell.

 According to the invention, the liner, the stirrup, the sole and the chassis are rigidly associated together thanks to at least one screw or bolt or equivalent passing through all of these elements and tightening them to each other.

 The invention relates in particular to a shoe-skate with two in-line rollers comprising a rigid chassis, in particular metallic - common to the two rollers extending under the sole. The liner, the stirrup and the sole are rigidly associated together with this chassis by means of a rear screw or bolt and a front screw or bolt.

 The invention also relates to a skate boot comprising in combination all or part of the characteristics above or below.

 The invention relates to an ice-skate or inline skate boot, that is to say a footwear assembly for skating comprising a footwear boot 1 which is rigidly and normally fixedly mounted on a skate 2, or which forms it - even a skate part 2. The skate 2 can be an ice skate comprising a blade mounted under the boot 1 or, as shown in the figures, an inline skate comprising at least two rollers 3, 4 mounted under the boot 1. Such in-line ice or roller skates are known in themselves and only their characteristics playing a specific role within the scope of the invention will be described, the other characteristics being considered to be incorporated by reference, as far as necessary.

 According to the invention, the boot 1 comprises a rigid sole 5 made of a hard and rigid synthetic material such as polyvinyl chloride or polypropylene or polyurethane. The boot 1 also includes a flexible boot 6 enclosing the foot having its rear part 7 rising at least above the ankle. The liner 6 is made of canvas or soft leather, or a flexible synthetic material like a basketball. The liner 6 may include locally reinforced portions 8, in particular at the location of the hooks or lacing orifices. The liner 6 is rigidly associated with the sole 5.

 According to the invention, the boot 1 also includes a rigid rear stirrup 9 which is rigidly associated with the sole 5. This stirrup 9 extends on each side of the rear part 7 of the liner 6 over most of its height to maintain the foot and prevent lateral flexions of the ankle while allowing forward and backward flexions. The stirrup 9 is made of a rigid synthetic material such as polyurethane. The boot 1 according to the invention essentially has the appearance and characteristics of a basket because the stirrup 9 does not extend over, and leaves uncovered, the front part 10 of the liner 6, in particular the part extending to from the rear region of the metatarsus.

 According to the invention, the stirrup 9 is rigidly associated with the sole 5 with a frame 11 of the shoe 2, frame 11 on which the blade or the rear caster 4 at least is mounted free to rotate.

 As a variant or in combination (not shown), the sole 5 can be combined with the chassis 11 supporting the blade or the rollers in line. In this case, the stirrup 9 is simply and directly rigidly associated with the chassis 11 which forms the sole for the liner 6.

 According to the invention, the boot 1 is mounted on at least one chassis 11 supporting a blade or the rollers 3, 4. In the embodiment shown, the chassis 11 is separate from the sole 5, and this chassis 11 is metallic, especially aluminum. According to the invention, the rear part 7 of the liner 6, the stirrup 9, the rear part 12 of the sole 5, and the chassis 11 supporting the blade or the rear wheel 4 at least, are rigidly associated together thanks to at least a screw or bolt 14 passing through all these elements 6, 9, 5, 11 and tightening them one on the other. Likewise, the front part 10 of the liner 6, the front part 15 of the sole 5 and the chassis 11 supporting the blade or the front caster 3 at least, are rigidly associated together thanks to at least one screw or bolt 13 passing through all these elements 6, 5, 11 and clamping them on top of each other.

 In the embodiment shown in the figures of a shoe-skate with two in-line rollers, and according to the invention, the shoe 2 comprises a rigid frame 11 common to the two rollers 3, 4 extending under the sole 5, and the liner 6, the stirrup 9 and the sole 5 are rigidly associated together with this chassis 11 by means of a rear screw or bolt 14 and a front screw or bolt 13. The chassis 11 forms a front yoke 48 and a rear yoke 49 for mounting the front 3 and rear 4 rollers respectively by means of pins 51, 52. A brake 50 is associated with the front of the chassis 11.

 The screws 13, 14 are flat head screws, inserted through the bottom of the liner 6 and covered by the inner sole of the liner (not shown). They pass through holes 53 before respectively 54 rear of the sole 5 and cooperate with threads 55 before respectively 56 rear of the chassis 11.

 According to the invention, the stirrup 9 is rigidly associated with the liner 6, in particular under the bottom 17 of the rear part 7 of the liner 6.

 According to the invention, the stirrup 9 consists of a single piece in one piece comprising two lateral wings 18a, 18b extending on each side of the rear part 7 of the liner 6, and of a core 19 connecting the lateral wings 18a, 18b through their lower part 20a, 20b.

 The core 19 of the stirrup 9 is rigidly associated with the bottom 17 of the rear part 7 of the liner 6, and with the rear part 12 of the sole 5 by the rear screw 14 which passes through a bore 57 of this core 19. In addition, this core 19 of the stirrup 9 is interposed between the bottom 17 of the rear part 7 of the liner 6 and the rear part 12 of the sole 5.

 As can be seen in the figures, the upper part 22 of the liner 6 from the front of the leg and the ankle and at least up to the front end of the metatarsus is free and constitutes the external wall of boot 1. The upper part 22 of the liner 6 supports means 23 for lacing or tightening the liner 6 on the foot.

 In the embodiment shown, the upper face 22 of the boot 6 is completely free and constitutes the external wall of the boot 1, and is therefore not covered with a closed rigid shell.

 Each lateral wing 18a, 18b of the stirrup 9 is generally in the form of a plate covering the rear lateral part of the bootie 6 from the bottom of the heel to above the ankle. Also, the core 19 of the stirrup 9 is in the form of a thin plate interposed between the sole 5 and the liner 6 and extending under the heel. The two side wings 18a, 18b have at least substantially the same shape and the same profile.

 According to the invention, the core 19 of the stirrup 9 is extended at its rear part by a rising flange 24 covering the heel of the liner 6 and connecting to each other over the height of this heel the rear lower parts 26a, 26b of the lateral wings 18a, 18b of the stirrup 9. The rim 24 extends and therefore connects the rear portions 20a, 20b of the lateral wings 18a, 18b at the rear over the entire height of the heel, that is to say -to say above the calcaneus.

 On the other hand, the upper parts 27a, 27b, and in particular the rear upper parts 28a 28b and the upper front parts 29a, 29b of the lateral wings 18a, 18b are generally distinct and distant from each other, and are two distinct portions separated without common edge of the stirrup 9. The rear upper parts 28a, 28b are generally distinct and spaced from each other from the top of the heel. But these rear upper parts 28a, 28b are connected to each other by means 31 of connection or clamping. These connecting or clamping means 31 for example consist of a non-elastic band in its own longitudinal direction. This strip 31 connects the rear upper extremities 32a, 32b of the lateral wings 18a, 18b to each other and is associated with each of these corners 32a, 32b rigidly by welding, sewing, gluing or the like.

 The upper front parts 29a, 29b of the lateral wings 18a, 18b of the stirrup 9 are generally distinct and distant from each other and, on their front edge 33a, 33b, support or are associated with (FIGS. 2 and 3 ) upper lacing or tightening means 34 which extend or complete the lacing or tightening means 23 of the bootie 6. Thus, the bootie 6 is generally trapped and tightened in the stirrup 9 between the rear edge 24 covering the heel and the means 34 for lacing or tightening. In Figure 1 eyelets 34 lacing are shown. These eyelets 34 are sewn to the liner 6 and to the stirrup 9 by a common seam.

 According to the invention, the front edge 33a, 33b of each lateral wing 18a, 18b of the stirrup 9 has a notch 35a, 35b, in particular so as to make the upper front part 29a, 29b flexible in flexion in particular to allow clamping of the stirrup 9 and of the liner 6 by the lacing or tightening means 34. This notch 35a, 35b is V-shaped, the tip of which is oriented towards the rear. The notch 35a, 35b is located at least substantially in the middle of the height of the front edge 33a, 33b -notably in the vicinity of, or facing, or immediately under the malleoli and at least substantially at the same height as the upper edge 36 from the rear edge 24 of the stirrup 9, or immediately under this upper edge 36-. The lower front part 37a, 37b of the lateral wing 18a, 18b is extended forward in the shape of a point.

 According to the invention, the lateral wings 18a, 18b of the stirrup 9 are rigidly associated - in particular sewn and / or glued - to the liner 6.

 Furthermore, each lateral wing 18a, 18b of the stirrup 9 has its thickness which varies from its peripheral edges 33a, 33b front, 38a, 38b upper, 39a, 39b rear, and to its central portion 40a, 40b located in look of the malleolus. The thickness of each wing 18a, 18b is less than its periphery and more important than its central region 40a, 40b. To do this, each wing 18a, 18b consists of a thin border 41a, 41b, of a peripheral portion 30a, 30b thicker than the fine border 41a, 41b, of a reinforced portion 42a, 42b of greater thickness. that the peripheral portion 30a, 30b and having a similar contour but less extended than the peripheral edges 33, 38, 39, and of a central portion 40a, 40b at least substantially circular opposite the malleoli, this central portion 40a, 40b having a greater thickness than the reinforced portion 42a, 42b. Each wing 18a, 18b therefore consists of a plurality of portions, the thicknesses of these portions increasing from the periphery towards the center of the wing 18a, 18b. The internal face 25 of the wings 18a, 18b is smooth and the increase in thickness is carried out on the external face 21 of the wings 18a, 18b (FIG. 4).

 According to the invention, the rigid sole 5 has a rigid flange 43 extending upwards on each side of the front side parts 44a, 44b and along the front part 10 of the liner 6. The rear parts 45a, 45b of the flange 43 are distant and distant from the stirrup 9, that is to say from the front lower parts 37a, 37b of the lateral wings 18a, 18b. The rim 43 is of low height, and in particular has a height of between 2 and 15 mm. This rim 43 constitutes a protective reinforcement and improves the lateral guiding of the pad by the front of the foot.

 According to the invention, the boot 1 further comprises a peripheral protective reinforcement 46 extending at least from the front lower parts 37a, 37b of the lateral wings 18a, 18b of the stirrup 9 forwards along the parts lateral medians 47a, 47b and front 44a, 44b of the bootie 6 and above the front end portion 10 of the bootie 6 corresponding substantially to the toes. The peripheral reinforcement 46 is rigidly associated - in particular sewn and / or glued to the liner 6. The peripheral reinforcement 46 can be extended (Figure 1) to the rear part 7 of the liner 6 opposite the wings 18a, 18b of the stirrup 9 In a variant not shown, the rear ends 48a, 48b of the reinforcement 46 are associated - notably sewn and / or glued - with the front lower parts 37a, 37b of the wings 18a, 18b of the lateral stirrup 9. The front edge 43 of the sole 5 covers over a certain height and partly the peripheral reinforcement 46 to the portion located furthest forward of this reinforcement. Thus, the peripheral reinforcement 46 is interposed between the front part 10 of the boot 6 proper and the flange 43 before the sole 5. The peripheral reinforcement 46 is rigidly associated - notably glued and / or sewn to the sole 5 and to the flange 43 before the sole 5. The peripheral reinforcement 46 consists of a rigid or semi-rigid synthetic material such as polyvinyl chloride or rigid polypropylene, but this material is less rigid and softer than that constituting the stirrup 9 and the sole 5. The reinforcement 46 is therefore similar to a traditional basketball reinforcement. Indeed, this reinforcement 46 essentially has a function of protection against impact or wear, and a support function, unlike the sole 5 and to the stirrup 9. The reinforcement 46 extends over the median lateral parts 47a, 47b of the liner 6 only over only part of their height. The reinforcement 46 however extends over the entire height of the rear part 7 of the liner 6. The reinforcement 46 can cover the liner 6 or form an integral part of this liner 6 by being associated with the other parts of this liner 6. The reinforcement 46 is rigidly associated, in particular sewn and / or glued to the stirrup 9. For example, the reinforcement 46 has its rear part sewn with the wings 18a, 18b of the stirrup 9 to the liner 6.

 Thus, an boot 1 according to the invention consists of a flexible liner 6 provided with a peripheral reinforcement 46, a rear stirrup 9 extending or covering the peripheral reinforcement 46 backwards and upwards, and a rigid sole 5 associated under the stirrup 9, the peripheral reinforcement 46, and the liner 6. The sole 5 rests on a common frame 11 for the two rollers 3, 4 or for the blade.

 This produces an inline skate bootie or an ice bootie whose boot 1 has the look, mechanical characteristics and comfort of a basketball, but which perfectly maintains the ankle and foot in order to avoid lateral bending untimely and perfect control of the skate in relation to the vertical position. The tests carried out have shown that such a skate effectively makes it possible to carry out all the possible evolutions with perfect control and increased comfort. In addition, the lightness obtained greatly facilitates acrobatic maneuvers.

 The description given above of a skate boot is given only by way of example, the invention being able to be the subject of numerous variants and being applicable in particular to other skate boots such as those comprising more than two casters in line.
