Description

  The present invention relates to footwear with studs such as sports shoes such as football shoes and golf shoes. The term “football” is intended to encompass all sports known as football, such as soccer, rugby, American football and Australian football.

  The stud is intended to provide traction with a type of ground engaging portion suitable for the sport involved. Thus, football studs tend to have relatively sharp ground piercing spikes, while golf shoe studs currently have relatively soft and obtuse ground gripping spikes. The stud is removably attached to the sole of the footwear product. A threaded spigot provided on the stud is used for attaching the stud. The threaded spigot engages in a correspondingly threaded socket. The socket is provided in a receptacle (receptacle) that is molded into the sole of the shoe or otherwise secured to the sole of the shoe. The screw can be a single thread or a multiple thread, and the stud and socket also incorporate a locking ratchet to prevent accidental loosening of the stud.

  The stud provides most if not all of the traction on the footwear and may be of a different type, even for one sport. Thus, a golf stud can have a dynamic spike that deflects when pressure is applied to the spike, or a static spike that does not flex. Dynamic spikes do not always flex as intended, depending on the surface to which pressure is applied or how it is applied.

  In the past, since most studs were circular or otherwise rotationally symmetric, there was no need to orient the rotational angle of the stud relative to the shoe sole. For this reason, the direction of the final rotation angle direction of the stud with respect to the sole of the shoe is irrelevant.

  However, the force applied to the stud is a special force or a relatively large force, such as a lateral force or a force caused by the shoe wearer rapidly accelerating forward. In some sports, it is more effective if the stud is in a specific orientation (the term “specific stud” is a rotationally asymmetric stud and a rotationally symmetric Used to include studs that are shaped but whose orientation with respect to the sole of the shoe is important). The studs that are oriented in a particular way must be oriented very accurately with respect to the shoe sole so that the studs can be guaranteed to work in the desired manner. Most known screws and locking ratchets cannot give this exact orientation. In accordance with the present invention, a system has been developed that ensures the correct orientation of the stud with respect to the receiving part. By determining the orientation of the receiving portion in the sole, the orientation of the stud with respect to the sole can be accurately determined.

  According to the present invention, an outsole for a footwear product with a stud includes a receiving portion for a stud that is oriented in a specific direction, and a traction element formed integrally with the outsole. Are structured and arranged to interact with each other when using footwear.

  The ability to accurately determine the orientation of the stud relative to the outsole means that the outsole can be designed so that the traction element cooperates with the stud to improve the overall traction of the outsole. It means that there is.

  Thus, if a golf shoe stud comprises a dynamic spike, the traction element can be formed on one or both peripheral sides of the at least one spike. In this case, the traction element can guide the spike as it deflects and also acts as a static or dynamic traction element. The traction element can extend from the outsole at any suitable angle. These traction elements can be V-shaped or triangular contours.

  The traction element may be designed to be complementary to the stud spike configuration. The form of the stud will depend on the position of the stud within the outsole and the force applied to the outsole during use.

  One embodiment of the invention is illustrated by way of example only in the accompanying drawings.

  The outsole 1 in FIG. 1 is for a golf shoe with a stud. The outsole 1 is molded from rubber and includes several receiving portions 2, and the receiving portions 2 are molded in the outsole 1 at appropriate positions on the sole 3 and the heel 4. Has been. Each of the receiving parts 2 is adapted to receive a stud 5 (only one of which is shown) oriented in a specific orientation. The stud 5 has a ground engaging spike 6. The outsole 1 has a traction element 7 formed integrally with the outsole, and the traction element 7 interacts with the spike 6 in use.

  Each of the studs 5 is a single-piece molded product of a plastic material. Each stud 5 has a flange 8. A threaded spigot 9 protrudes from the upper part of the flange 8. On the other hand, a spike 6 protrudes from the lower side of the flange 8. There are three dynamic spikes 6a that deflect when pressure is applied, and five static spikes 6b that do not flex.

  The spigot 9 is provided with a multi-threaded external screw 10 having a relatively steep helix angle so that the stud 5 can be inserted into the receiving portion 2 in half rotation. In order to define the initial position of the stud 5 with respect to the receiving part 2, one thread of the screw in the spigot 9 is different from the other thread, and the screw 10 is engaged only at one position of the stud 5 with respect to the receiving part 2. To be able to.

  Due to the relatively steep helix angle of the screw, the frictional resistance of the stud 5 against screw loosening is relatively small. For this reason, the stud 5 and the receiving part 2 have a locking means 11. The locking means 11 includes an elastic post (post) 12 arranged in a ring shape on the stud 5. The elastic post 12 cooperates with teeth 25 arranged in a ring shape in the receiving part 2. When the teeth 25 are engaged with the posts 12, the posts 12 bend, and the teeth 25 are engaged so as to enter between the posts 12, so that the locking means is in an interengaged state. This serves to fix the stud 5 in the receiving part 2 and to define its final position with respect to the receiving part 2. The stud 5 is then correctly oriented in the receiving part 2 when fully engaged.

  The elastic post 12 extends in the axial direction from the upper portion of the flange 8. These posts surround the spigot 9 and form a concentric ring with the spigot 9. There are six posts 12 in an evenly distributed arrangement around the stud axis. The axial extension of each of the posts 12 is about ½ of the axial height of the spigot 9, and each of the posts is elastic in the radial direction. Each radially outer surface of the post 12 has a lower partial cylindrical portion 13 and an upper partial conical portion 14. Each top surface 15 of the post 12 is angled upward toward the spigot 9 so that each radially inner surface 16 of the post 12 has a maximum axial height. The radially inner surface 16 is generally convex toward the spigot 9, with a central convex region 17, a first peripheral end 18 having a concave contour profile toward the spigot 9, and toward the spigot 9. And a second peripheral end 19 having a convex outline. When the stud 5 is inserted, the first peripheral end 18 becomes the front end, the second peripheral end 19 becomes the rear end, and vice versa when the stud is removed. The concave contour profile of the first peripheral end 18 reduces the resistance when the stud is inserted, while the convex contour profile of the second end 29 provides a greater resistance when the stud is removed.

  The receiving part 2 is also a single-piece molded product of a plastic material. The receiving part 2 comprises a disc top plate 20 having a central boss 21 depending from the receiving part. The receiving portion 2 is fastened (fixed) to the outsole 1 by a top plate 20, and the top plate is a means (not shown) for ensuring that the receiving portion 2 is correctly oriented with respect to the outsole 1. )).

  The boss 21 has a solid cylindrical wall 22. Formed on the cylindrical wall 22 is an internally threaded socket 23 adapted to receive the spigot 9. The socket 23 also has a multi-thread screw. One of the thread grooves is different from the other grooves and is complementary to one thread of the spigot 9 screw which is also different from the other threads. On the radially outer surface 24 of the boss 21, the other portion of the locking means 11 is formed as a tooth 25 extending in the axial direction and arranged in a ring shape. The teeth 25 protrude radially outward from the surface 24. The tooth 25 has a triangular cross section as a whole, but has a rounded apex.

  The distance that the teeth 25 project radially from the socket axis is substantially equal to the distance of the inner surface of the post 12 at the first peripheral edge 19. For this reason, there is a radial interference between the teeth 25 and the post 12, which creates a frictional resistance against the relative rotation of the stud 5 and the receiving part 2.

  The stud 5 is attached by inserting the spigot 9 into the socket 23. There are only one position where the threaded connection can be engaged because there are different threaded threads and grooves. As the spigot 9 rotates, it is pulled into the socket 23 so that the teeth 25 engage the post 12. Post 12 flexes elastically and radially to allow teeth 25 to move through (pass through) post 12. If the spigot 9 is rotated 180 degrees, the stud 5 is completely inserted into the receiving portion 2 and is fixed by engaging the teeth 25 and the post 12 with each other.

  In this way, the position of the stud 5 in the receiving portion 2 is accurately determined by the screwing and locking means 11. Since the position of the receiving portion 2 with respect to the outsole 1 is also accurately determined, the spikes 6a and 6b of the stud 5 are in a precisely determined position with respect to the outsole 1, and therefore the spike is out of use when in use. It is possible to interact with the traction element 7 of the sole 1.

  As shown in the drawing, four traction force elements 7 are provided, with one traction force element on each of the peripheral sides of each of the dynamic spikes 6a. Each of the traction elements 7 has a substantially triangular shape and protrudes from the outsole 1. The axial height of each of the traction elements 7 is lower than the axial extension of the dynamic spike 6a. The illustrated element 7 protrudes substantially perpendicular to the outsole 1 but may have any suitable angle.

  When the shoe is worn during use, the dynamic spike 6a bends radially outward due to the weight of the wearer applied to the shoe. The movement is guided by the traction element 7, which then engages the ground and provides further traction as a static spike.

  It will be appreciated that the structure and arrangement of the traction element 7 can be designed to be complementary to the stud 5 used. For this reason, the tractive force element 7 can have various forms and can act dynamically or statically. It will also be appreciated that different thread forms and locking means can be used for the studs and receptacles if desired.
