Definitions
- This invention relates to footwear. More particularly, the invention is directed to improve spikes.
- Spikes are commonly installed on the bottom of footwear for skidproof and grip effects when shoes wearers stand or walk on grass or places with soft soil. Hence, footwear with spikes is mostly designed for exercise doers like track and field and golfing, etc.
- Spikes are usually divided into two types. One is single column spikes and the other is disc-shaped spikes. Though several spikes are arranged on the bottoms of shoes for the first type; however, not many spikes are installed on the bottoms due to cost and design. Consequently, this type has single-point grip that is not sufficient. Furthermore, the reacting force is sent back to the feet of the wearers stamping on the ground, which causes discomfort for the wearers. A number of spikes are installed to enhance the skidproof effect for the second type. Nevertheless, the design of a rigid disc with many spikes is only effective in slip resistance without any real grip.
- the main purpose of this invention is to provide spikes that may solve the aforementioned problems.
- Each spike may deviate flexibly to create excellent skidproof and grip effects.
- this invention relates to an improved spike with a receptacle installed in a sole of a shoe and a base and several connecting seats integrated around the edge of the base in one piece flexibly moving in proportion to the base.
- Several spikes are installed unto individual connecting seats extruding the sole.
- Spikes 10 in a preferred embodiment of the present invention are installed unto a flexible sole 21 of a shoe 20 and constituted by one receptacle 12 and several tacks 14.
- the receptacle 12 is made of flexural metal material and has a base 22 and three connecting seats 24 formed by bending the piece extruding the outer edge of the base 22 for slight flexible deviation relative to the base 22.
- One foundation 26 is bent and formed on the edge of the base 22.
- One stand 28 is connected to the foundation 26 and bent into a circle for the hole 29.
- Each tack 14 is made of metal material harder than that of the receptacle 12 and inserted into corresponding hole 29espectively.
- the receptacle 12 is situated in the sole 21 and the end of each tack 14 extrudes the sole 21 at a proper length. Consequently, every connecting seat 24 and tack 14 are enclosed by the flexible material of the sole 21 The flexibility of the sole 21 and slight flexible deviation of the connecting seat 24 relative to the base 22 are ingeniously designed for a proper grip for each tack 14.
- each spike 10 installed on the bottom of the shoe 20 and the ground also varies as shown in Fig3.
- every tack 14 on the sole 21 will be compressed resulting in a rebounding force that will coordinate the slight expanding elastic recovery of each connecting seat 24 in proportion to the base 22. Consequently, the expanding strength of each tack 14 can be increased and the skidproof and gripping effects of every tack 14 can be enhanced.
- each tack 32 can be clipped tightly and the excellent skidproof and gripping effects disclosed above will be achieved.
- each connecting seat 42 Both sides of the foundation 43 of each connecting seat 42 are bent relatively and corresponding to the hole 46 of the stand 44 so that the inner end of each tack 48 can be propped up against the end surface of the foundation 43. As a result, each tack 48 won't squeeze towards the inner end of the connecting seat 42 affecting gripping effect.
- the spike of this invention works with the wrapped connecting seat and the sole flexible material of the tack perfectly via each connecting seat deviating opportunely and flexibly. A better grip is generated by changing elastic recovery appropriately no matter what angle of deviation is when each tack contacts the ground.
- This invention indeed has more excellent skidproof effect compared with other commonly known spikes.
Abstract
Description
- This invention relates to footwear. More particularly, the invention is directed to improve spikes.
- Spikes are commonly installed on the bottom of footwear for skidproof and grip effects when shoes wearers stand or walk on grass or places with soft soil. Hence, footwear with spikes is mostly designed for exercise doers like track and field and golfing, etc.
- Spikes are usually divided into two types. One is single column spikes and the other is disc-shaped spikes. Though several spikes are arranged on the bottoms of shoes for the first type; however, not many spikes are installed on the bottoms due to cost and design. Consequently, this type has single-point grip that is not sufficient. Furthermore, the reacting force is sent back to the feet of the wearers stamping on the ground, which causes discomfort for the wearers. A number of spikes are installed to enhance the skidproof effect for the second type. Nevertheless, the design of a rigid disc with many spikes is only effective in slip resistance without any real grip.
- The main purpose of this invention is to provide spikes that may solve the aforementioned problems. Each spike may deviate flexibly to create excellent skidproof and grip effects.
- Accordingly, to achieve the aforementioned purpose, this invention relates to an improved spike with a receptacle installed in a sole of a shoe and a base and several connecting seats integrated around the edge of the base in one piece flexibly moving in proportion to the base. Several spikes are installed unto individual connecting seats extruding the sole.
- A description of the content and the technology of this invention along with drawings is made in detail as follows:
- Fig1 is an exploded view of a first preferred embodiment of the present invention;
- Fig2 is an exploded view in parts of the first preferred embodiment of the present invention.
- Fig3 is a view of the first preferred embodiment of the present invention installed on the sole showing spikes inserting to the ground.
- Fig3A is an amplification display view in parts of Fig3.
- Fig4 is another view of the first preferred embodiment of the present invention installed on the sole showing spikes inserting to the ground.
- Fig4A is an amplification display view in parts of Fig4.
- Fig5 is an exploded diagram of the second preferred embodiment of the present invention.
- Fig6 is an exploded diagram of the third preferred embodiment of the present invention.
- First, refer to Figs. 1 thru 3.
Spikes 10 in a preferred embodiment of the present invention are installed unto aflexible sole 21 of ashoe 20 and constituted by onereceptacle 12 andseveral tacks 14. - The
receptacle 12 is made of flexural metal material and has abase 22 and three connectingseats 24 formed by bending the piece extruding the outer edge of thebase 22 for slight flexible deviation relative to thebase 22. Onefoundation 26 is bent and formed on the edge of thebase 22. Onestand 28 is connected to thefoundation 26 and bent into a circle for thehole 29. - Each
tack 14 is made of metal material harder than that of thereceptacle 12 and inserted into corresponding hole 29espectively. - Thus, the
receptacle 12 is situated in the sole 21 and the end of eachtack 14 extrudes the sole 21 at a proper length. Consequently, every connectingseat 24 andtack 14 are enclosed by the flexible material of the sole 21 The flexibility of the sole 21 and slight flexible deviation of the connectingseat 24 relative to thebase 22 are ingeniously designed for a proper grip for eachtack 14. - As the angle of the feet and the ground changes slightly while walking, the angle formed by each
spike 10 installed on the bottom of theshoe 20 and the ground also varies as shown in Fig3. When eachtack 14 draws in slightly, everytack 14 on the sole 21 will be compressed resulting in a rebounding force that will coordinate the slight expanding elastic recovery of each connectingseat 24 in proportion to thebase 22. Consequently, the expanding strength of eachtack 14 can be increased and the skidproof and gripping effects of everytack 14 can be enhanced. On the contrary, when eachtack 14 expands outwardly a little bit as shown in Fig4, everytack 14 outside the sole 21 will be pressed resulting in a rebounding force that will draw thetack 14 in and coordinate the slight drawn-in elastic recovery of each connectingseat 24 relative to thebase 22. In this way, the drawn-in strength of eachtack 14 will be motivated and the skidproof and gripping effects can be enhanced. - Refer to the
spike 30 in Fig5 for another preferred embodiment of the present invention. The structure is identical to that of thespike 10 in general. The differences are the cone-shaped end of eachtack 32 and adent 36 on the outside of each connectingseat 34 corresponding to thetack 32 to prevent eachtack 32 from getting loose from the connectingseat 34 or being squeezing into the inner end of the connectingseat 34 because of an external force. Therefore, eachtack 32 can be clipped tightly and the excellent skidproof and gripping effects disclosed above will be achieved. - Refer to the
spike 40 in Fig6 for still another preferred embodiment of the present invention. Both sides of thefoundation 43 of each connectingseat 42 are bent relatively and corresponding to thehole 46 of thestand 44 so that the inner end of eachtack 48 can be propped up against the end surface of thefoundation 43. As a result, eachtack 48 won't squeeze towards the inner end of the connectingseat 42 affecting gripping effect. - Accordingly, the spike of this invention works with the wrapped connecting seat and the sole flexible material of the tack perfectly via each connecting seat deviating opportunely and flexibly. A better grip is generated by changing elastic recovery appropriately no matter what angle of deviation is when each tack contacts the ground. This invention indeed has more excellent skidproof effect compared with other commonly known spikes.
Claims (8)
- Improved spikes are installed inside a flexible sole of a shoe and consist of a receptacle having a base and several connecting seats integrated around the edge of the base in one piece flexibly moving in proportion to the base. Several spikes are installed unto individual connecting seats extruding the sole. Accordingly, each connecting seat and partial spikes are wrapped up by the flexible sole.
