Description

Technical Field

[0001] This invention relates to a testing fixture, and more particularly to a testing fixture for a shoe sole with a realistic effect. Background Technology

[0002] Most existing shoe sole testing mechanisms use testing machines to test the characteristics of the shoe sole under test by repeatedly pressing, hitting, or rubbing it. These characteristics include, but are not limited to, abrasion resistance, toughness, or structural strength. However, this traditional testing method is not designed to simulate the actual use conditions of users, and therefore it is less able to test the characteristics of the shoe sole under test in actual use.

[0003] To test the characteristics of a shoe sole in actual use, another testing method has been proposed on the market. This involves placing the sole in a sample shoe and having a real person wear it and perform various actions to observe its condition after prolonged use, thus analyzing its characteristics. However, this method of testing with real people is not only costly in terms of personnel and time-consuming due to human limitations, but it is also easily disrupted or impossible to implement due to unforeseen circumstances (such as a pandemic). Summary of the Invention

[0004] According to one embodiment of the present invention, a test fixture for a shoe sole includes: a shoe sole component including a heel area; a heel cushioning component disposed on the heel area of ​​the shoe sole component; a shoe sole connecting component for connecting the shoe sole component, such that the heel cushioning component is located between the shoe sole component and the shoe sole connecting component; a cushioning airbag, which is annular in shape, disposed on the shoe sole connecting component; a torque connector for being fitted into the cushioning airbag, one end of the torque connector being connected to the shoe sole connecting component; and an attachment component disposed on the cushioning airbag and connected to the other end of the torque connector.

[0005] In some embodiments, the sole further includes a toe area and a plurality of simulated toes located within the toe area.

[0006] In some embodiments, the torque connector includes an elastic block and two connecting portions located at opposite ends of the elastic block, the two connecting portions of the torque connector being connected to the sole fitting and the attachment assembly, respectively.

[0010] In some embodiments, the sole connector includes a groove for receiving a portion of the heel cushioning and limiting the displacement of the heel cushioning.

[0011] In some embodiments, the attachment assembly includes a carrier, and at least one of the sole attachment and the carrier includes an annular groove for receiving a portion of the cushioning airbag and limiting the displacement of the cushioning airbag.

[0012] In some embodiments, the sole component further includes a plurality of spikes or spike holes.

[0013] In some embodiments, the heel cushioning and at least a portion of the sole are made of an elastic material.

[0014] In some embodiments, at least one of the sole joint and the support member is made of metal.

[0015] In some embodiments, the attachment assembly includes a carrier and a locking fastener, the carrier being disposed on the airbag and fitted over the other end of the torque connector, and the locking fastener being used to secure the other end of the torque connector.

[0016] In some embodiments, the sole component further includes a receiving groove for receiving the heel cushioning component and at least a portion of the sole coupling component.

[0017] In some embodiments, the receiving groove extends from the midfoot area of ​​the sole to the heel area.

[0018] In some embodiments, the sole member includes a positioning portion, the sole connector includes a positioning portion, and the positioning portion of the sole member is used to contact the positioning portion of the sole connector to limit the horizontal displacement of the sole connector relative to the sole member.

[0064] In the following detailed description, numerous specific details are set forth in order to provide a thorough understanding of the invention. However, those skilled in the art will understand that the invention can be practiced without these specific details. In other instances, well-known elements have not been described in detail so as not to obscure the invention.

[0065] The testing fixture provided by this invention is suitable for testing the sole structure and materials of various shoe models, such as, but not limited to, soccer shoe soles. To concisely illustrate the spirit of this invention, the following explanation will use the testing of the bottom structure and materials of a soccer shoe sole as an example. Please refer to... Figures 1 to 4 The present invention, according to one embodiment, provides a shoe sole testing fixture, which includes a shoe sole component 10, a heel cushioning component 20, a shoe sole joint component 30, a cushioning airbag 40, a torsion connector 50, and an attachment component 60.

[0066] The sole component 10 is a test object having the bottom structure and material of a sole to be applied to a soccer shoe, comprising a toe area R1, a midfoot area R2, and a heel area R3. These three areas correspond to the positions of the toes, forefoot, and heel of the human foot, respectively. Figure 3 As shown. A plurality of spikes 13 are provided on one surface 11 of the sole component 10, and these spikes 13 are distributed in the toe area R1 and the heel area R3 of the sole component 10. A sidewall 14 protrudes from the opposite surface 12 of the sole component 10. The sidewall 14 is annular and surrounds the midfoot area R2 and the heel area R3 of the sole component 10, forming a receiving groove 15 together with the surface 12. At least one positioning portion 16 is provided on the bottom of the receiving groove 15 (i.e., the surface 12 located within the receiving groove 15). A plurality of simulated toes 17 are further provided on the surface 12 of the sole component 10 within the toe area R1, thereby simulating the pressure of a human toe on the sole, to more closely resemble the actual situation of the sole during use. Furthermore, a limiting portion 18 is provided on the sidewall 14 of the sole component 10. The material of some or all of the sole component 10 may be, for example, but not limited to, elastic materials, which may be, for example, but not limited to existing or known elastic materials used in soles.

[0067] A heel cushioning member 20 is disposed within the heel area R3 of the receiving groove 15. A comb-like structure 22 is provided on a surface 21 of the heel cushioning member 20 facing the sole member 10. A protrusion 24 is provided on the opposite surface 23 of the heel cushioning member 20 away from the sole member 10. The heel cushioning member 20 may be manufactured, for example but not limited to, by injection molding, and the heel cushioning member 20 is made of an elastic material, for example but not limited to, thermoplastic polyurethane (TPU).

[0068] The sole connector 30 can be placed into the receiving groove 15 and covered by the sidewall 14 of the sole component 10, thereby restricting the horizontal movement of the sole connector 30 relative to the sole component 10. In this embodiment, a positioning portion 32 can be provided on a surface 31 of the sole connector 30 facing the sole component 10, the shape and number of which can match the positioning portion 16 of the sole component 10. A groove 33 is provided on the surface 31 of the sole connector 30. A limiting portion 35 is also provided on the side surface 34 of the sole connector 30, the shape and number of which match the shape and number of the limiting portion 18 of the sole component 10. The material of the sole connector 30 can include, for example, but is not limited to, metal. When the heel cushioning member 20 and the sole connector 30 are assembled on the sole 10, the heel cushioning member 20 is located between the sole 10 and the sole connector 30, and the comb-like structure 22 of the heel cushioning member 20 abuts against the surface 12 of the sole 10 to simulate the cushioning function of the human heel muscles; the protrusion 24 of the heel cushioning member 20 can be inserted into the groove 33 of the sole connector 30 to limit the horizontal movement of the heel cushioning member 20 relative to the sole connector 30; the positioning portion 32 of the sole connector 30 also engages with the positioning portion 16 of the sole 10 to prevent the sole connector 30 from moving horizontally relative to the sole 10; and the limiting portion 35 of the sole connector 30 engages with the limiting portion 18 of the sole 10 to limit the vertical movement of the sole connector 30 relative to the sole 10.

[0069] The cushioning airbag 40 may be annular and have an air chamber 41. The cushioning airbag 40 may be disposed on the sole joint 30. For example, an annular groove 37 may be further provided on the opposite surface 36 of the sole joint 30, such that one end 42 of the cushioning airbag 40 can be placed into the annular groove 37 to limit or prevent horizontal movement of the cushioning airbag 40 relative to the sole joint 30.

[0070] The torque connector 50 includes an elastic block 51 and two connecting portions 52 and 53 located at opposite ends of the elastic block 51. At least one annular groove 512 is provided on the side surface 511 of the elastic block 51 to increase the torque capacity of the torque connector 50 by improving its flexibility. The torque connector 50 may be manufactured, for example but not limited to, by injection molding after embedding a washer and screw, and the elastic block 51 may be made, for example but not limited to, TPU.

[0071] The torque connector 50 can be fitted into the annular cushioning airbag 40 and can connect to the sole connector 30. For example, a groove 38 and a fixing hole 39 located within the groove 38 can be further provided on the surface 36 of the sole connector 30, and an annular groove 37 surrounds the groove 38 and the fixing hole 39, such as... Figure 2As shown; therefore, when assembling the torque connector 50 to the sole connector 30, the connecting part 52 of the torque connector 50 can be inserted into the fixing hole 39 of the sole connector 30 after passing through the channel 43 of the cushioning airbag 40, so that the elastic block 51 of the torque connector 50 can be surrounded by the cushioning airbag 40, and one end of the elastic block 51 can be placed into the groove 38 of the sole connector 30. The positions of the cushioning airbag 40 and the torque connector 50 can correspond to the position of the human ankle. In this way, the cushioning airbag 40 can be used to simulate the shock absorption capacity of the ankle when the human foot moves quickly, and the torque connector 50 can be used to simulate the rotational resilience and support of the human ankle.

[0072] The attachment assembly 60 includes a carrier 61 and a locking fastener 62. The carrier 61 may be made of metal, for example, but not limited to. The carrier 61 is disposed on the airbag 40 and connects to the connection portion 53 of the torque connector 50. For example, the carrier 61 has at least one annular groove 612 (e.g., but not limited to two), a groove 613, and a fixing hole 614 located within the groove 613 on a surface 611 facing the airbag 40. The annular grooves 612 surround the groove 613, and the position, shape, number, and size of the annular grooves 612 may be determined according to the position, shape, and size of the opposite end 44 of the airbag 40. The type of the locking fastener 62 may match the type of the connection portion 53; for example, when the connection portion 53 is a screw, the locking fastener 62 may be a nut. When the end 44 of the cushioning airbag 40 is placed into the annular groove 612 of the carrier 61, and the connecting portion 53 of the torque connector 50 is inserted into the fixing hole 614 of the carrier 61, the elastic block 51 of the torque connector 50 will enter the groove 613 of the carrier 61, and the cushioning airbag 40 and the torque connector 50 will be located between the carrier 61 and the sole joint 30. At this time, the connecting portion 53 protruding from the opposite surface 615 of the carrier 61 can be locked by the locking fastener 62 to limit the vertical movement of the cushioning airbag 40 and the torque connector 50 relative to the sole 10.

[0073] In addition, one or more fixing holes 616 can be added to the surface 615 of the support member 61 as needed, such as Figure 1 , 2 As shown in Figure 3, the entire test fixture can be detachably assembled into a robotic arm for subsequent sole testing procedures (such as, but not limited to, tests on sole abrasion resistance, spike strength, or comparison of properties between different sole materials).

[0074] When conducting shoe sole testing procedures, such as Figure 4As shown, the robotic arm moves the test fixture of the present invention to a test platform and repeatedly moves the test fixture relative to the test surface TS of the test platform to simulate the state of a real person performing various movements after wearing football shoes with the material of the sole component 10 and the structure on the surface 11, such as, but not limited to, walking, running, jumping, kicking, or tackling. The material of the test surface TS of the test platform can be, for example, but not limited to, turf. During the relative movement, when the sole component 10 of the test fixture contacts the test surface TS of the test platform, the cushioning airbag 40 will deform due to the force applied to the test fixture by the robotic arm and the reaction force from the test surface TS, such as... Figure 5 As shown, this accurately simulates the cushioning provided by the ankle when the foot lands.

[0075] While the above embodiments are illustrated using soccer shoes as examples, the present invention is not limited thereto. In fact, the structure (i.e., the bottom structure) on the surface 11 of the sole 10 can be designed according to the specific shoe model to which it is applied. For example, if applied to running shoes, the studs 13 on the bottom structure of the sole 10 can be omitted; if applied to track and field spikes, the bottom structure of the sole 10 can be modified to include stud holes for inserting studs.

[0076] Although the sole component 10 in the above embodiments is provided with sidewalls 14, allowing the sole connector 30 to be connected to the sole component 10 by inserting into the receiving groove 15 of the sole component 10, the present invention is not limited thereto. In other embodiments, the sidewalls may be omitted from the sole component, and corresponding engaging structures may be added to the sole component and the sole connector, allowing the sole connector to be connected to the sole component. Alternatively, the sole component and the sole connector may be engaged by locking.

[0077] While the present invention has been disclosed above with reference to the foregoing embodiments, these embodiments are not intended to limit the invention. Any modifications, refinements, and combinations of embodiments made without departing from the spirit and scope of the invention are within the scope of patent protection of the present invention. For the scope of protection defined by the present invention, please refer to the appended claims.
