Description

Method for locking nail shoes by using inertia

The invention relates to a method for locking a spike shoe by using inertia, in particular to a spike shoe suitable for sports footwear, such as a track shoe, a replaceable wear component footwear, including but not limited to casual shoes and jogging shoes, soccer boots And golf shoes, "soccer" refers to all known football sports, such as soccer, rugby, American and Australian football.

A stud means that it is suitable for providing a frictional force during exercise and has a grounding portion, so the soccer shoe tends to have relatively pointed soles, and those golf shoes have several relatively soft and blunt gripping nails. Footwear with replaceable wear components tends to have relatively rounded soles to reduce drag and wear when landing, and to avoid injury to the floor and floor. The studs can be separately assembled to the sole of the footwear and can be molded or secured to the sole by bolting one of the studs to an opposing threaded seat.

The threaded joint must be designed to ensure that the stud remains in a position even if a large amount of force is applied and cannot be accidentally released. The conventional stud has a single thread or a multi-thread thread, and the single thread is the simplest thread form, and when it is loosened, it has a larger resistance than the multi-thread thread, and the thread of the bolt and the threaded seat is multi-turn. A strong bond can also be provided after rotation. However, whether a single or multi-threaded thread is used, both the stud and the threaded seat include a latching ratchet to prevent the spike from accidentally coming loose. Typically, both the stud and the threaded seat have A set of teeth that engage each other when the studs are inserted into the threaded seat, the teeth being configured to allow the stud to be placed in any of a number of positions relative to the threaded seat when the stud is fully inserted.

The application No. 80202035 of the Chinese patent application "the seat for spikes" is a design for improving the previously corresponding occlusal teeth and replacing the spiral of the double starting line to prevent the stud from loosening.

The application of the Chinese Patent No. 90128130 - "nail shoes" is a design in which an underlying toothed member is fitted with a screw assembly to prevent the stud from loosening.

The application No. 92108164 of the Chinese patent application "nail shoes" is a design that utilizes a spiral assembly for preventing the reverse of the locking accessory ribs to prevent the stud from loosening.

The application for patent No. 92108165 in China - "nail shoes" is a design that utilizes the locking effect of the friction elements to prevent the studs from coming loose.

The application for patent No. 97200043 - "stud base structure" is a design that utilizes the blocking effect of the positioning block which can prevent reversal to prevent the stud from loosening.

None of the above inventions discloses the use of inertial forces as a means of locking spikes.

Therefore, in some relatively high-force motions on the stud, such as lateral forces or because of the force generated by the wearer's forward acceleration, if the stud can utilize the inertial force, the method of locking the spike will be It's more effective, and it's easier to loosen and replace the studs.

SUMMARY OF THE INVENTION A primary object of the present invention is to provide a shoe shoe assembly with a counter-time locking that ensures that a stud can be locked with its opposing threaded seat and receiving seat by inertial force.

In the normal gait cycle, the outer side of the heel or the middle (heel touches the ground) will land first, then quickly move inward to the inner side of the heel, and then gradually shift to the outside of the forefoot through the diagonal direction. Its outer end terminates at about the end of travel, and then shifts inward again, eventually coming out of contact with the ground from the inside or the middle of the forefoot.

The present invention relates to a spike shoe, comprising a combination structure of a stud and a receiving seat, the stud includes a grounding portion, and the stud and the receiving seat are fixed to each other by a multi-threaded joint portion, and the multi-thread thread is combined. The part comprises a bolt and a threaded seat, the bolt is located on one of the part of the stud and the receiving seat, the threaded seat is located on the other part of the stud and the receiving seat, and the bolt can correspond to the rotating screw Into the threaded seat, when the bolt is completely screwed into the threaded seat and the parts such as the stud and the receiving seat are resistant to loosening, one of the parts can be used to form at least each other by the inertial force locking locking mechanism. Closely, the latching mechanism includes at least one locking accessory that locks in a reverse time direction, the configuration is such that when the traveling, the force exerted by the ground on the latching fitting is opposite to the moment formed by the center of the latching fitting, and vice versa. A lock mechanism for locking in a time direction is configured such that the force exerted by the ground on the latching fitting relative to the moment formed by the center of the latching fitting is a forward direction.

The multi-threaded joint can be a double, three or more thread that reduces the number of turns required for the stud to attach or disassemble.

Preferably, the two or all of the threads have the same structure, and the starting position of the stud relative to the receptacle can be determined by the number and/or position of the latching fittings. For example, generally only the right side of the heel and the outside of the heel may have only three time-locking fittings alone, or further three inner-side locking fittings on the inner side. For example, in general, the outer side of the heel after the right foot can only have three locking accessories in the time direction, and the heel in the left foot is also disposed on the outer side only with three reverse time locking components. Or, generally, the outer side of the heel after the right foot can only have three locking components in the time direction, and three reverse time locking components are arranged on the inner side, and oppositely, the outer side of the heel after the left foot has three reverse time blocking. Accessories, on the inside are configured with three time-locking accessories.

If for certain movements, it is only necessary to consider the moment formed by the ground force relative to the center of the locking fitting in the time direction or the reverse time direction to determine the locking direction of the locking fitting, thereby locking it with the inertial force. Compared with the threaded seat and the accommodating seat without complicated blocking mechanism, the method is more suitable for the locking mechanism of any structure, which is convenient for ensuring precise locking of the stud relative to the accommodating seat, and the stud is also It can be a special directional stud, especially a non-rotationally symmetrical stud.

Figure 1 shows a combination of footwear (not shown) suitable for use in a replaceable wear resistant component, including upper 1, midsole 2, support 3 and outsole combination 4, which includes right a spiral stud 6 and a left spiral stud 8, which can be used to be screwed into and housed in one of the right helix receptacles 5, and the left helical stud 8 can be used for screwing in and It is housed in one of the left helix housings 7, which can be shaped or otherwise attached to the sole or heel of the aforementioned athletic shoe.

The stud 6 or 8 can be an integral or composite component of any metal, ceramic or any plastic material and has a locking helical structure. The sole has a grounding portion protruding downwardly and an external bolt from the upper side. Protruding, the receiving seat 5 or 7 must be used in conjunction with the directionality of the sole and the stud, and the orientation of the stud in the receiving seat is the first step herein.

In the normal gait cycle, the outer side of the heel or the middle (heel touches the ground) will first land, then quickly move inward to the inner side of the heel, and then gradually shift to the outer side of the forefoot through the diagonal direction to The outer side rotates to the inner side of the sole of the foot, and finally comes into contact with the ground from the inner side of the forefoot or the middle of the sole of the foot at the end of the march. Therefore, according to the transmission trajectory of the above-mentioned force, the force of the ground to the outside of the left heel is formed with respect to the center of the combination of the spiral stud 8 and the accommodating seat 7. The acting moment is the left spiral direction, so the locking mechanism on the outer side of the left heel includes a locking fitting having a fitting portion formed by the left helical direction locking stud 8 and the receiving seat 7, the locking mechanism ensures the left foot and the foot The studs on the outside can be automatically tightened in the left spiral direction without loosening by the force of the ground.

The force acting on the inner side of the heel of the left foot relative to the left helix direction of the left heel, and the acting moment of the center of the combination of the spiral stud 6 and the receiving seat 5 The right helix direction, so the locking mechanism on the inner side of the left heel includes a locking fitting having a fitting portion formed by the right helical direction locking spike 6 and the receiving seat 5, the locking mechanism also ensuring that the stud can utilize the ground The force is automatically tightened in the right spiral direction without loosening.

According to this principle, if the stud is to be provided on the outer side of the forefoot of the left foot, it at least includes a locking mechanism that automatically screws in the left spiral direction without loosening, and if the inside of the forefoot needs to be provided with a stud, At least one locking mechanism that automatically screws in the right spiral direction without loosening is included.

When the outer sole of the heel is made of a hard metal or ceramic material, if the material of the midsole 2 is an elastic foam material, the bottom material of the corresponding upper area may be selected to be soft and elastic. Material, if the inner side of the stud is selected to be less wear-resistant and elastic material such as plastic material, the material of the bottom 2 in the corresponding upper area can be selected as a hard foaming material, so that the configuration can be better. The balance state allows the wearer to get a more stable effect when walking.

If the material of the midsole 2 is a flexible and highly deformable hollow structure such as an air cushion, a recess 9 for filling the support piece 3 may be disposed under the air cushion, and a hard metal or a sole may be selected when the outer side of the heel is In the case of ceramic material, the air cushion pocket 9 in the corresponding upper area may select the support piece 3 with softer hardness, or even the support piece, and the inner side of the shoe nail is selected to be less wear-resistant and elastic material such as plastic material. , the air cushion pocket 9 in the corresponding area above it can choose harder hardness The support piece 3, such a configuration, can achieve a better balance state, not only to achieve a more stable effect when the wearer walks, but also when the sole of the heel is grounded, the stud of the outer hard material of the heel is squeezed by the air cushion. The shape of the air cushion above the stud is indented and deformed, which in turn causes a secondary spring effect, which not only has better shock absorbing effect, but also increases the energy recovery rate when the original air cushion is not inflated from 44% to 60%, and the energy recovery rate after inflating 10 PSI. From 54% to 64%, it is one of the big discoveries to improve the sole function.

2 is a schematic view showing the opposite locking direction of the left and right heel of the spike shoe according to the present invention. The right foot is locked in a clockwise direction, that is, in a right spiral direction, and the left foot is locked in a counterclockwise direction or a left spiral direction.

Figure 3 is a cross-sectional view showing a single thread of a stud base assembly having an opposite helical locking direction in accordance with the present invention.

4 shows an insole of a replaceable wear-resistant component according to an embodiment of the present invention. A stud can be placed on the inner side of the rear heel at the same time, and the material and quantity of the inner and outer studs can be According to the gait of the wearer, for example, the outer eight-type walker, the outer side of the heel is generally more wearable than the inner side, so more shoe nails are used, and the material can be wear-resistant metal or ceramic material, and the opposite heel. The inner side is generally less prone to wear, so it is conceivable to use less stud placement and use a less wear-resistant material such as plastic material. Compared with the outer eight-type walker, the inner side of the heel of the inner eight-type walker is generally more wearable than the outer side, so the wear-resistant metal or ceramic material is used, and the outer side of the heel is considered to be a material that is less wear-resistant. Such as plastic materials. Since the studs are replaceable, the new studs can be replaced to avoid the knee and spine or soles caused by the sole pressure and the center of gravity of the soles, and the wearer's correct wearing period is extended.

Figure 5 shows a shoe stud placed only on the left and right heels in accordance with an embodiment of the present invention. The outer side, while the number and material of the outer studs can be adjusted according to the wearer's gait. Since the outer stud exceeds the sole height, the outer side of the sole is higher than the inner side, further causing the body center of gravity to tilt inward and causing the sole The pressure center is offset to the medial side, generally for rehabilitation and physical therapy. It is used as a pain symptom in patients with degenerative arthritis that improves the medial knee injury. It can reduce the contraction moment in the knee while traveling, and the outside of the heel is generally more prone to wear. Therefore, the wear-resistant metal or ceramic material is used, and since the stud is replaceable, the effect of reducing the contraction moment of the knee can be achieved by changing the height of the stud, and the pressure of the sole can be avoided due to the wear of the sole. The knee and the spine or the sole of the foot derived from the deviation of the center of gravity of the body, and the height of the stud can be changed in consideration of the improvement of the patient with degenerative arthritis, and the replaceable stud can also extend the wearing period of the shoe correctly.
