Skate with removable shoe

Abstract

 A skate including a frame (2) provided with a resting base for a shoe (5) for walking and from which two supporting wings for wheels (7) protrude in a downward region. Devices (21a, 26) for a temporary connection to the shoe are associated with the base and/or with the frame and are located at at least three regions for the transmission of the forces applied laterally by the foot, such as the regions adjacent to the big toe, the little toe and the heel of the foot.

Description

[0001] The present invention relates to a skate with removable shoe.

[0002] A first conventional roller skate comprises a flat plate for resting a soft-type shoe normally used for walking; pairs of lugs protrude below the plate approximately opposite the heel and toe regions, and two wheels are pivoted between each pair of lugs and are arranged mutually side by side along an axis which runs transversely to the plate. Connection to the soft shoe is provided by a band which passes below the plate at the toe region and wraps around the shoe in an upward region; the band is closed at its end, for example by a lace. Furthermore, at the heel region there is a second band which transversely wraps around the foot instep in order to allow to fasten the shoe to the plate. This old type of skate is practically no longer used for sports practice because of its poor control while skating.

[0003] Skates have been provided which are essentially constituted by a frame which is usually U-shaped, with wings which are turned down toward the ground, and above which a shoe is rigidly coupled. Wheels are freely pivoted between the wings of the frame and are thus mutually in line.

[0004] The connection between the frame and the shoe occurs at the sole of the shoe, which is rigid, by virtue of suitable devices such as screws, bolts, rivets, et cetera.

[0005] The shoe can therefore be of the kind constituted by an upper which is rigidly coupled to the sole or by a shell made of plastic, with the optional association of a suitable cuff also made of plastic.

[0006] This second type of skate essentially has the drawback that it can be used only for sports skating and requires the user to have a separate kind of shoe to perform normal walking.

[0007] Canadian patent No. 2,101,718 partially overcomes this drawback and describes an in-line roller skate in which the wheel supporting frame has, at the heel region, lateral wings for containing a shell. The wings can be rigidly coupled to the frame in a downward region and have, perimetrically with respect to the sole, a small raised perimetric rim and a small toe cup which allows to insert a flexible-type shoe. Furthermore, at the shell there are suitable lateral seats for bands which allow to lock the shoe inside the shell.

[0008] Even this type of skate, however, has drawbacks, because it is structurally complicated, owing to the number of components that must be mutually assembled in various manners, and because the shoe that is used has to be specific for the intended application, since it includes a front flap made of plastic and parts adapted to improve comfort at the malleolar region.

[0009] Furthermore, the shoe cannot be used as a walking shoe even if it is optionally disconnected from the shell, since the front flap is free with respect to the rest of the upper and would therefore not allow the user to use it appropriately in any case.

[0010] An aim of the present invention is to solve the described technical problems, eliminating the drawbacks of the cited prior art. An object of the invention is to provide a skate which allows to achieve optimum control of the implement during sports practice. A further object is to provide a skate which allows the user to have the same shoe used for skating also available for walking.

[0011] A further object is to provide an invention which is structurally simple and has a limited number of components.

[0012] A further object is to provide a skate whose use for sports practice or for walking can be chosen and obtained quickly and simply by the user without requiring particular tools.

[0013] A further important object is to provide a skate in which the shoe that composes it provides optimum comfort conditions for the user.

[0014] A further object is to provide a skate which allows to use a shoe which has characteristics suitable for walking and at the same time allows optimum transmission of forces from the foot to the sports implement.

[0015] Still a further object is to provide a skate which is reliable and safe in use, has low manufacturing costs and can also be manufactured with conventional machines and equipment.

[0016] This aim, these objects and others which will become apparent hereinafter are achieved by a skate as claimed in the appended claims.
Advantageously, the at least three regions are arranged adjacent to the big toe, the little toe and the heel of the foot.

[0017] Further characteristics and advantages of the invention will become apparent from the detailed descriptions of some particular but not exclusive embodiments, illustrated only by way of non-limitative example in the accompanying drawings, wherein:

[0018] With reference to the above figures, the numeral 1 designates a skate which includes a frame 2 which is essentially constituted by a base 3 for resting the sole 4, or part thereof, of a shoe 5.

[0019] Two wings, designated by the reference numerals 6a, 6b, protrude from the frame 2 on the opposite side with respect to the shoe 5. The wings are arranged approximately parallel to each other and multiple wheels 7 are transversely pivoted between them and are thus arranged mutually in-line.

[0020] Shoe 5 is a shoe of the kind suitable to allow walking and is therefore for example a gym shoe, leisure shoe, trekking shoe, and is accordingly of the kind which includes a sole 4 which is flexible and has no parts, such as for example blades, for strengthening or engagement.

[0021] First grip means are associated laterally to base 3 and are constituted by at least one first pair of jaws, designated by the reference numerals 8a, 8b, which in the particular illustrated embodiment are essentially triangular with rounded corners and in which the base side 9 is pivoted at the perimetric edge 10 of base 3 at the metatarsal region 11.

[0022] In particular, the first pair of jaws 8a, 8b is not arranged exactly transversely to base 3 but is slightly staggered so as to affect, more particularly, the big toe region 12 and the little toe region 13.

[0023] Advantageously, first pair of jaws 8a, 8b is pivoted on a pivot 14, coaxially to which there is a flexible part, such as a spring, which forces the positioning of first pair of jaws 8a and 8b toward the upper surface 15 of base 3 and thus forces clamping at upper 16 of shoe 5.

[0024] As an alternative, first pair of jaws 8a and 8b can be rigidly coupled to perimetric edge 10 of base 3, so as to protrude from upper surface 15 thereof at an acute angle, assuming a counterclockwise rotation to be positive: in this manner, the first pair of jaws is slightly inclined above base 3 and the jaws can be spaced apart elastically toward the outside of the base so as to allow temporary coupling to the second engagement means.

[0025] First pair of jaws 8a, 8b has a central cutout region 17a, 17b which accommodates the second engagement means, which protrudes laterally from shoe 5 at the big toe region 12 and at the little toe region 13.

[0026] The second engagement means is constituted by raised portions 18a, 18b which are shaped complementarily to the central cutout regions 17a, 17b, so that they can be accommodated therein without being able to perform relative movements.

[0027] Rotation of the shoe at the metatarsal region 11 and movement of the shoe with respect to the longitudinal axis of frame 2 are accordingly both prevented, and this allows to immediately transmit forces from the foot to the frame and increases sensitivity for the user.

[0028] The skate is also constituted by third means for locking heel 19 and for the lateral containment of shoe 5. The third devices are constituted by a bracket 20 which is shaped like an open loop and the tips of which are laterally and transversely freely pivoted at wings 6a and 6b of frame 2.

[0029] Bracket 20 has two arms 21a, 21b which are optionally shaped so as to adhere to wings 6a, 6b without interfering with base 3 of frame 2. The arms arrange themselves laterally to base 3 and are connected by a cross-member 22 which is arranged at a region which is adjacent to the upper perimetric edge 23 of shoe 5 in the rear region thereof.

[0030] Proximate to the perimetric edge it is possible to associate, at shoe 5 and therefore to the rear of the shoe, a device for the temporary engagement of cross-member 22, such as a lever or tooth 24.

[0031] When cross-member 22 is arranged adjacent to the shoe and optionally locked by virtue of the lever or tooth 24, arms 21a and 21b are accommodated at suitable seats 25 formed laterally to the shoe at the upper.

[0032] One thus obtains optimum transmission of lateral forces from the ankle to the frame; locking of the shoe with respect to the frame is also enhanced.

[0033] Force transmission is also optimized because the forces are transmitted directly from the upper part of the shoe to the lower part, located adjacent to the wheels, of the frame that constitutes the skate.

[0034] A third means for transversely locking the shoe is associated at the first temporary grip means and is constituted by at least one first band 26 which passes at suitable slots 27a, 27b formed at the side of each first pair of jaws 8a, 8b which is directed toward the front end of base 3.

[0035] First band 26 can thus be fastened transversely to shoe 5 at a region which joins the big toe region and the little toe region. The degree of fastening can be selected for example by means of temporary retention means, at the facing surfaces of the first band 26. The temporary retention means may be for example bands known commercially by the trade mark Velcro.

[0036] It has thus been observed that the invention has achieved the intended aim and objects, a skate having been provided which allows to use a shoe which has optimum comfort characteristics for the user and can be associated at the frame quickly and simply by the user and at the same time allows the optimum transmission of forces from the foot to the frame by virtue of the connection of the shoe at three regions which coincide with those where the most intense force is applied by the foot.

[0037] The particular means that are used also allow to keep the shoe in position with respect to the frame, avoiding any rotation or movement thereof and thus increasing directionality for the user and safety in use.

[0038] The skate according to the invention is susceptible of numerous modifications and variations, all of which are within the scope of the same inventive concept.

[0039] Thus, for example, as shown in Fig. 5, at the perimetric edge 110 of the base 103 of the frame 102 it is possible to apply a first pair of jaws 108a, 108b, so as to affect the big toe region 112 and the little toe region 113, and a second pair of jaws 128a, 128b which are identical to the preceding ones and affect the lateral region of the heel of the skater.

[0040] A first band 126 and a second band 130, identical to the preceding one, can thus interact with these first and second pairs of jaws.

[0041] In this case, too, there is a third means, such as a bracket 120 which conveniently affects the lateral regions of the frame 102 and of the second pair of jaws 128a, 128b. Arms 121a and 121b of the bracket are allowed to move mutually apart slightly during the mutual spacing of second pair of jaws 128a, 128b.

[0042] The shoe of course also includes, although they are not illustrated, first and second raised portions which are shaped complementarily to the central recesses 117 of the first and second pairs of jaws and protrude laterally to the upper in the big toe, little toe and heel regions.

[0043] Fig. 4 illustrates a shoe 205 in which, inside or outside the upper 216, there is an insole 231 constituted by a member which is torsionally rigid but flexible during walking and has a first rear lug 232, which is suitable to increase the resistance of the sole to lateral flexing, and a pair of second lateral lugs 233a and 233b which are arranged at the raised portions 218 which interact with the first temporary grip means which are associated laterally to the base of the frame.

[0044] Fig. 6 is a view of a further embodiment, on which the third means for locking the heel 319 is constituted by two lateral brackets 334, which are rotatably associated, at a first end 335, at a wing 306 of the frame 302, preferably at the pivot of a wheel 307.

[0045] Each one of the lateral brackets 334 is associated, at a second end 336, with a means for connection to the shoe 305; the means are constituted for example by a third band 337 which is similar to the preceding ones, surrounds the upper part of the shoe 305 and passes at a suitable pair of slots 327a, 327b formed longitudinally to each lateral bracket 334.

[0046] Advantageously, the configuration of the lateral brackets is slightly curved, with the concavity directed toward the rear part of the structure 301.

[0047] Fig. 1 and Fig. 6 also illustrate a means which is suitable to limit the forward flexing of the third means; the means is constituted by a block, designated by the reference numerals 38 and 338, which can be rigidly or adjustably coupled to the wings of the frame 2, 302 and is essentially shaped like a prism with a triangular base; one of its surfaces makes contact with the arms 21a, 21b of the bracket 20 or with the perimetric edge 339 which is directed toward the front part of the structure 301 of each lateral bracket 334.

[0048] The block is adjusted along an axis which is approximately parallel to the axis of the arms and the lateral bracket.

[0049] With reference to Figs. 7-15, the numeral 401 designates a skate which includes a frame 402 which is essentially constituted by a base 403 for resting the sole 404, or part thereof, of a shoe 405.

[0050] Two wings, designated by the reference numerals 406a, 406b, protrude from the frame 402 on the opposite side with respect to the shoe 405; the wings are arranged approximately parallel to each other and multiple wheels 407 are associated between them and are thus arranged mutually in-line.

[0051] Shoe 405 is of the kind suitable to allow walking and is therefore for example a gym shoe, leisure shoe, trekking shoe, and is accordingly of the kind which includes a sole 404 which is flexible and has no parts, such as for example blades, for strengthening or engagement.

[0052] First grip means are associated laterally to the base 403 and are constituted by a pair of raised portions 408a, 408b, which in the particular illustrated embodiment are essentially prism-shaped with rounded corners.

[0053] A fastening means is provided at the raised portions 408a, 408b and is constituted by a pair of jaws 409 which are essentially band-shaped and can be associated, by virtue of per se known systems suitable to adjust the fixing tension, for example the system known commercially by the trade mark Velcro.

[0054] Advantageously, each one of jaws 409 internally includes a sawtooth part 410 which is suitable to cooperate with a corresponding sawtooth part 411 formed on the outer side of upper 416 of the shoe 405, in order to prevent sliding of the shoe with respect to the jaws and therefore with respect to the skate.

[0055] In a rear region, proximate to heel 431 of the shoe, base 403 has a second pair of raised portions 412a, 412b which are substantially similar to the raised portions 408a, 408b and are suitable to support a quarter-like part 413 constituted by wings 414a, 414b which are pivoted to the raised portions and by a lug 424 which can slide with respect to the quarter 413 through tab 415 and is pivoted to base 403 of the skate.

[0056] Lug 424 includes a rear tooth 417 and, at the rear tooth, a locking band 419 which can be closed on the foot instep by virtue of per se known tension adjustment systems, for example of the kind known commercially by the trademark Velcro.

[0057] Shoe 405 includes, at the sole 404, a first pair of recesses 418a, 418b suitable to receive the first raised portions 408a, 408b of the skate and a second pair of recesses 420a, 420b suitable to receive the second raised portions 412a, 412b of the skate. Moreover, the shoe 405 includes, at the heel region, a rear recess 421 which is suitable to receive the rear tooth 417 of the lug 424.

[0058] The operation of the skate according to the invention is extremely simple.

[0059] It is in fact sufficient to insert the shoe in the skate while keeping the quarter 413 rotated backward, so as to engage the recesses 418a, 418b, 420a, 420b with the respective raised portions 408a, 408b, 412a, 412b of the skate and then rotate quarter 413 forward, inserting rear tooth 417 in rear recess 421 of the shoe.

[0060] Once jaws 409 and 419 have been tightened, the shoe is firmly associated with the skate by virtue of the coupling of the teeth with the recesses.

[0061] It has thus been observed that the invention has achieved the intended aim and objects, a skate having been provided which allows to use a shoe which has optimum comfort characteristics for the user, the shoe being associable at the frame quickly and simply by the user whilst allowing optimum transmission of forces from the foot to the frame also by virtue of the connection of the shoe at three regions which coincide with those where the foot applies the greatest force.

[0062] The particular means used also allow to keep the shoe in position with respect to the frame, preventing any rotation or movement thereof, and thus increasing directionality for the user and safety in use.

[0063] Figs. 16 and 17 are views of a skate 501 according to another aspect of the invention, which includes a frame 502 which is essentially constituted by a base 103 for resting the sole 404 or part thereof of a shoe 405 which is similar to the one described above.

[0064] Two wings protrude from the frame 502, on the opposite side with respect to the shoe 405; only one wing, designated by the reference numeral 506a, is shown; the wings are approximately parallel to each other, and multiple mutually in-line wheels 507 are associated between the wings.

[0065] A first grip means, constituted by two raised portions 508a, 508b, is associated laterally to the base 503; in the particular embodiment that is shown, the raised portions are essentially prism-shaped with rounded edges.

[0066] At the raised portions 508a, 508b there is a fixing means which is constituted by two jaws 509 which can be associated by virtue of per se known systems suitable to adjust the fixing tension, for example by virtue of the system known commercially by the trade-name Velcro.

[0067] Advantageously, each one of the jaws 509 internally includes a sawtooth part 510 which is suitable to cooperate with a corresponding sawtooth part 411 formed on the outer side of the upper 416 of the shoe 505, in order to prevent sliding of the shoe with respect to the jaws and therefore with respect to the skate.

[0068] To the rear, in a position which is proximate to the heel 431 of the shoe, the base 503 has a second pair of raised portions 512a, 512b which are substantially similar to the raised portions 508a, 508b and are suitable to support a quarter-like part 513 constituted by wings 514a, 514b which are pivoted to the raised portions.

[0069] A rear tooth 517 is fixed at the heel and supports a locking band 519 which can be closed onto the foot instep by virtue of per se known tension adjustment systems, for example of the kind known commercially by the trademark Velcro.

[0070] In a manner which is similar to that of the preceding case, the shoe 405 includes, at the sole 404, a first pair of recesses 418a, 418b which are suitable to accommodate the first raised portions 508a, 508b of the skate 501, and a second pair of recesses 420a, 420b which are suitable to receive the second raised portions 512a, 512b of the skate 501. At the heel region, the shoe 5 furthermore includes a rear recess 21 which is suitable to receive the rear tooth 517 of the skate 501.

[0071] The operation of the skate 501 according to the invention is extremely simple and similar to the preceding one, the only difference being that since the lug 414 is omitted, the shoe is inserted in the skate by lifting the toe and engaging the rear recess 421 with the fixed tooth 517 and by then resting the sole 404 on the base 503, engaging the recesses 418a, 418b, 420a, 420b with the teeth 508a, 508b, 512a, 512b of the skate.

[0072] Once the jaws 509 and 510 have been tightened, the shoe is firmly associated with the skate by virtue of the coupling of the teeth with the recess.

[0073] The materials used, as well as the dimensions, may of course be any according to the requirements and the state of the art.
