DETAILED DESCRIPTION OF THE INVENTION

[0001]

FIELD OF THE INVENTION The present invention relates to athletic shoes for use on the lawn, and more particularly, without adversely affecting the lawn.
A traction system for improving traction of a wearer.

[0002]

The need for improved traction on grass is well known. Dedicated shoes for many different sports, such as baseball, football, soccer and golf, etc., have structures with shoe soles to improve traction. Throughout this specification, it has long been known to provide golf shoes with relatively large metal spikes for traction, taking golf as a representative example.

Almost as long as they have been used, golf spikes (and other similar structures found in athletic shoes for sports on the grass)
It is known to adversely affect the lawn of golf courses (or other sports surfaces), especially greens. When a large spike drags his feet on the green surface, especially as golfers do,
Tearing the green surface, leaving "spike marks", damaging the carefully trimmed surface and adversely affecting the trajectory of the dropped golf ball. Traces of spikes in golf
As is well known, the rules of the game have been applied in view of their existence (the rule forbids repairing spike marks before falling). In addition to affecting the player's ball drop, the marks of the spikes also affect the ground mechanic. Ground technicians have to repair the various greens of the golf course over hours after a day of play by a number of spiked golfers.

[0004] Not only are the traces of spikes annoying to players and ground technicians, spikes in traditional golf shoes affect not only the green but also the condition of the lawn throughout the golf course. First, spikes penetrate the ground a significant distance and often damage parts of the grass above the roots, known as "heads".

[0005] Injuries to the roots often kill plants. Second, the spikes are weeds and grasses (eg, Po
carry undesired plant seeds, including a. annua), plant those seeds in green and grow the undesired plants.

[0006] Traditional metal golf spikes also
It can also damage the floor surface of a golf clubhouse or, in fact, make certain clubhouse floor surfaces, such as marble, slippery. Traditional metal golf spikes even damage paved outdoor sidewalks.

One known solution to the problem of traditional golf spikes is described in US Pat. Nos. 5,259,129 and 5,367,793, assigned to the present assignee. These U.S. patents are incorporated herein by reference in their entirety. These patents show a golf skid attached to a golf shoe attachment similar to that designed for traditional spikes. This non-slip is preferably for generating a plurality of gripping forces, mainly a frictional force, in a plurality of directions.
Consisting of a plastic material having a plurality of ribs for distributing the weight of the golfer, preferably having a convex lower surface, without perforating the lawn, thereby mitigating the aforementioned adverse effects.

[0008]

However, the anti-skid of the above patents does not completely solve the problem of providing traction without damaging the lawn. First, this non-slip can leave a depression on the grass surface, especially the green, and can take a significant amount of time to replace. Second, this anti-skid cannot provide traction on all surfaces that approaches that provided by traditional golf spikes. In particular, it is on wet grass surfaces as well as on steep slopes. Third, due to the material from which they are made and the fact that they are raised from the back of the shoe, this slip may fall off the shoe when it encounters obstacles.

[0009] Further, the anti-skid of the above patent is less likely to damage the floor and sidewalk of a clubhouse than traditional metal golf spikes, but it does not completely eliminate such damage, and You can still slip on the surface.

[0010] A system for providing traction in golf shoes (and other lawn sports shoes) that does not adversely affect the lawn, but provides the desired level of traction under as many different conditions as possible. It is desirable to be able to provide.

It would be desirable to be able to provide a traction system that resists detachment from the shoe in which it is used.

It is further desirable to be able to provide a traction system that is less likely to damage pavements and floors.

[0013] It is an object of the present invention to provide traction in golf shoes (and other lawn sports shoes) that does not adversely affect the lawn, but provides a desirable level of traction under as many different conditions as possible. To provide a system for

[0014] It is also an object of the present invention to provide a traction system that resists detachment from the shoe in which it is used.

It is a further object of the present invention to provide a traction system that is less likely to damage pavements and floors.

[0042]

DETAILED DESCRIPTION OF THE INVENTION In accordance with the present invention, traction for athletic activity on a grass surface is provided by providing an athletic shoe having an area having a relatively large number of relatively small bumps. Provided. In some embodiments, for example, the back and most of the heel have a relatively large number of relatively small bumps. Thus, instead of a relatively large number of 10 or 12 metal golf spikes in a golf shoe, a large number (eg, from about 35 to about 200, preferably from about 100 to about 200) There are relatively small bumps, which may be called small spikes. The miniature spikes of the present invention provide traction by physical interengagement of grass surfaces with grass leaves, but do not penetrate the ground because they are low or, if so, ignore them Penetrate as much as possible. Thus, it provides better traction than the non-slip described in the above-assigned patents, but does not cause the damage associated with traditional large metal spikes.

The small spikes of the present invention are relatively dense on the back surface of athletic shoes. However, if they are too dense, the space between them can become clogged with mud and grass chips, reducing the traction provided. Therefore, the small spikes must have sufficient spacing to avoid clogging. Furthermore, if the small spikes are too dense, they can act as a single mass, creating depressions in the grass surface of the lawn without mechanically engaging the grass leaves, thus providing traction. No offer. It has been found that small spikes should have a spacing of about two to about four times the height of each small spike. This height is selected to allow engagement with grass leaves to achieve traction without penetrating the ground. In one preferred embodiment, the height of each mini-spike is about 0.08 inches (about 2.0 mm) and the spacing between the mini-spikes is about 0.25 inches (about 6.35 mm). . Another way to quantify the separation between small spikes is by density. For small spikes about 0.08 inches (about 2.0 mm) high, preferably between about 3 and about 25 small spikes per square inch (about 0.47 and about 0.47 per square centimeter) Between 3.88 small spikes, and more preferably about 7 per square inch.
And about 25 small spikes (between about 1.09 and about 3.88 per square centimeter). In a particularly preferred embodiment for use on a golf course, the number of small spikes is about 17 per square inch (about 2.6 per square centimeter).
4). In each case, the small spikes should be far enough apart to prevent clogging.

In a preferred embodiment for golf course use, each mini-spike is preferably about 0.08
It has a height of inches (about 2.0 mm). The width of the base of each mini-spike is preferably approximately the same as the height of the mini-spikes so that the columns are sufficiently stiff to prevent bending.

The width of each miniature spike preferably varies in the height direction and most preferably decreases continuously from the base to the tip. A particularly preferred shape for small spikes is
A truncated cone with a base and height of about 0.08 inches (about 2.0 mm) and a flat circular tip about 0.05 inches (about 1.27 mm) in diameter. The miniature spikes should preferably not have a point. Because sharp, small spikes wear more quickly than those with blunt tips. Because of this, not only to avoid tearing the leaves of the grass, but also to avoid injuries when the wearer accidentally scrapes the wearer's skin or the skin of others with the tip of a small spike. It is also particularly preferred, though not absolutely, that the small spikes are not made of metal. A preferred material is an elastic polymer material. A particularly preferred elastic polymer material is polyurethane. However, any resilient polymer material can be used, provided that it has sufficient attrition resistance to withstand a significant number of wears.

The preferred construction of the mini spike is to cover a large area on the back and heel of the shoe with the mini spike. Small spikes are preferably not molded directly to the back or heel. Because they are preferably at least several times the motor event of interest for which they were designed (eg,
They should have sufficient abrasion resistance to be used for (a few rounds of golf), but they must also not be so hard as to damage the lawn. Therefore, they eventually wear out and need to be replaced. Therefore, small spikes should be mounted so that they can be removed and replaced by the wearer as needed.

In one such preferred system, a first mat or pad covering most of the sole of the shoe (providing small spikes at the arch portion is not harmful and not contrary to the principles of the present invention, Small spikes are provided on the second mat or pad that covers most of the heels of the shoe, except for those parts of the arch where the small spikes typically do not touch the ground, and therefore do not provide any advantage). . The pads are preferably detachable fasteners, particularly preferably hook and loop fasteners (often V
(Referred to as ELCRO®), with the hook portion preferably attached to the shoe and the loop portion preferably attached to a removable and replaceable pad. As the small spike wears, the wearer simply separates the hook and loop fastener, removes the pad, and installs a new pad.

To prevent the tip of the pad from coming off due to ground obstructions, recesses are preferably provided in the back and heel, and the pads are preferably received in the recesses.
The depth of each recess is preferably approximately equal to the sum of the thickness of the mat or pad itself (except for the small spikes) and the thickness of both the hook and loop fastener layers.
Thus, the surface of the mat or pad on which the spikes are raised is flush with the back or heel. Thus, the possibility that the tip of the pad is caught by the obstacle is small. The placement of such recesses also substantially eliminates depressions in the grass surface of the lawn due to pad thickness.

Instead of hook and loop fasteners, the pads can be attached to the back or heel by a strong pressure sensitive adhesive. When the pad needs to be replaced, the adhesive is heated (eg, using a hand dryer for the hair) and the worn pad is removed by softening. A new pad with new adhesive is preferably provided having a release paper covering the adhesive. The wearer peels off the release paper, exposes the adhesive, and attaches the pad to the shoe. This adhesive attachment is particularly suitable when no recess is provided in the back or heel. This is because the two layers of hooks and loop fasteners and pads are of substantial thickness rising from the shoe. However, the adhesive also
It can be used even if there are recesses. In fact, such an adhesive is a preferred method of attaching itself to a shoe when hook and loop fastener materials are used.

Alternatively, a screw (which may require the installation of a tapped hole in the shoe) or a detachable fastener such as a bayonet-type or snap-type fastener (having a suitable engagement structure for the shoe). The pad can be attached to the back or heel by mechanical attachment.

Another suitable system for attaching a small spike to an athletic shoe is to attach it to the shoe in the same manner as a traditional golf spike or a non-slip described in the above-assigned patents assigned to the assignee of the present invention. It is to provide small spikes for anti-slip. Such a non-slip according to this embodiment of the present invention may have a small spike extending from one surface and a disc-shaped flange with a threaded shaft extending from the opposite surface, known spikes or It is particularly useful for existing athletic shoes (especially golf shoes) that have a socket for screws to accept the anti-skid. The non-slip is preferably molded from a similar elastic material as described above, and a metal shaft can be attached to the molded flange, but preferably the screw shaft is molded along the remaining non-slip . The resiliency of the flange increases the resistance of the anti-skid so that it does not come off by obstacles. That is, the cleat does not come off, but usually deforms, and then recovers its shape when an obstacle passes by.

The non-slip flange is preferably as thin as possible to minimize depressions in the grass surface of the lawn. Preferably, the flange is at most about half the height of the small spikes. In the most preferred embodiment, the height of the small spikes is about 0.08 inches (about 2.80 inches).
0 mm), and the flange thickness is preferably about 0.04 inches (about 1.0 mm). When non-slip is used on athletic shoes with recesses to be inserted, the thickness of the flange is less critical. The flange is preferably concave on the back-facing side, flattening as the non-slip fits against the back, providing a better seal and tensioning such that the non-slip does not become loose. Provide an effect.

Hereinafter, the present invention will be described with reference to the drawings.

FIGS. 1 to 5 show a first preferred embodiment of the present invention, in which each pad 11, 12 with a small spike 13 according to the present invention
6 and heel 17 are mounted in respective recesses 14,15. As shown in FIGS. 2 and 4, each pad 11, 12 preferably has a small spike 1 on one side.
It has three rows, and a layer of loop portions 40 of hook and loop fastener material attached to the other side. Each recess 14, 15 is preferably lined with a layer of complementary hook portions 41 of hook and loop fastener material. The hook portion 41 preferably comprises a strong heat and pressure sensitive adhesive 20.
Are attached to the inner surfaces of the recesses 14,15. The loop portion 40 is preferably attached to the pads 11, 12 by a similar adhesive layer (not shown).

With the hook and the loop-type fastener reversed, the loops and the pads 11,
Although a hook portion can be provided on the back of 12, the portion is preferably arranged as shown. If the loop part is
If it is a "permanent" part, i.e. a part that is mounted in the recesses 14, 15 and is replaced when the pad wears, the loop will eventually wear and the hook part of the pad will be replaced by a loop for a firm installation. Insufficient engagement with the part cannot be achieved. The hook portion is more durable and easily retains the fastening force, and is therefore suitable as a "permanent" portion. However, if either fastener portion 40, 41 is installed as a "permanent" portion within recesses 14, 15, if worn, the adhesive layer 20 is preferably heated (e.g., a hair hand). With a dryer), the adhesive becomes sufficiently soft and the fastener portions 40, 41 can be removed. The new fastener portions 40, 41 are preferably
Covered with release paper (not shown),
It is provided by the built-in adhesive 20. The user
Peel off the release paper and stick new fasteners 40, 41 inside recesses 14,15.

As described above, the depths of the recesses 14 and 15 are
Preferably, the thickness of the pads 11,12 is substantially equal to the sum of the two hooks and the loop fastener portions 40,41 so that the small spikes 13 are raised pads 11,12.
Are substantially coplanar with the surface of the sole 16 or the heel 17, respectively, as shown in FIG. Therefore, in the present embodiment, the thickness of the pads 11, 12 is not important.

The area of the back 16 and the heel 17 covered by the small spikes 13 is smaller than the complete area shown in FIGS. One uncovered area is the area of the arch 30 and typically does not touch the ground. But,
Although rare, and providing some traction, small spikes 13 may be provided in the arch 30 if desired. Another part of the back and heel area that may not be covered is the border 18, which usually defines the recesses 14, 15. It is not necessary to provide recesses 14,15. In that case, the pads 11 and 12 extend to the tip of the back 16 and the heel 17. However, if recesses 14, 1
If the pad 5 is not provided, the pads 11 and 12 are easily damaged or come off during use. Therefore, it is preferable that such recesses 14 and 15 are provided.

As mentioned above, like the pads 11, 12, the small spikes 13 are preferably made of an elastic polymeric material which has sufficient abrasion resistance to be used for at least several rounds of golf, particularly preferably Is molded from polyurethane. The small spikes 13 can be mechanically combined with the grass leaves without penetrating the ground or with minimal ground penetration on less dense types of grass, such as the short cut surfaces of golf greens. It is long enough to engage. As mentioned above, the preferred height 42 of the small spikes 13 is about 0.08 inch (about 2.0 mm). Also, as described above, the width of each small spike 13 preferably varies along its height, and preferably decreases continuously as it moves away from the pads 11,12. The width 43 of the base of each small spike 13 is preferably approximately the same as the height 42 to prevent the small spikes 13 from bending and losing effect, so that the width 43 is also
Preferably, it is about 0.08 inch (about 2.0 mm). Most preferably, each small spike 13 has a base and height of about 0.08 inch (about 2.0 mm), and about 0.08 inches (about 2.0 mm).
A truncated cone with a substantially flat tip having a diameter 44 of 5 inches (about 1.27 mm).

The spacing of the miniature spikes 13 is preferably chosen such that the miniature spikes 13 are sufficiently far apart so that they do not plug. Preferably, the distance of the small spikes 13 is from about 2 to about 4 of the height of the small spikes 13
It is twice. More preferably, it is about three times the height of the small spikes 13. Therefore, about 0.08 inch (about 2.0 mm)
Small spike 13 having a height of
3 is preferably about 0.25 inches (about 6.3 inches).
5 mm).

In the second preferred embodiment shown in FIG. 6, the pads 11 and 12 are mounted on the respective surfaces of the back 16 and the heel 17 which are not recessed. Preferably, the pads 11, 12 are attached by a heat-sensitive, pressure-sensitive adhesive (not shown) such as the above-mentioned adhesive 20, so that when the pads 11, 12 are worn, the adhesive is removed as described above. It can be removed by heating. The new pads 11, 12 are preferably provided by an adhesive covered by a release layer, as described above. Release layer is removed and new pad 1
1 and 12 are attached. In the present embodiment, as shown, a boundary 18 is maintained. However, in this embodiment, when the tip of the pad extends to the tip of the back 16 or the heel 17, the pads 11, 12 may be more easily detached, even though the pads 11, 12 may be more easily detached.
However, there is no reason why it cannot extend to the tip of the back 16 or the heel 17. In this embodiment, the thickness of the pads 11, 12 is more important than in the first preferred embodiment 10. This is because, in this embodiment, this contributes to creating a depression on the grass surface of the lawn. Therefore,
In this embodiment 60, it is preferred that the pads 11, 12 have a thickness at most about half the height of the miniature spikes 13. Otherwise, the pads 11, 12 are identical to the pads 11, 12 in the first preferred embodiment. Thus, in the most preferred form of this embodiment 60, the pads 11, 12 have a thickness of about 0.04 inches (about 1 mm).

In either the first embodiment 10 or the second embodiment 60 of the present invention, the pads 11, 12
Or, by screws (not shown),
It can be attached to the back 16 or the heel 17. Self-tapping screws may be used, and more preferably, in known athletic shoes, a tapped hole provided to accept a non-slip or spike is provided on the back 16 or heel 17.
May be provided. Similarly, a suitable socket or slot is provided on the back 16 or heel 17 and using removable fasteners such as bayonet fasteners (not shown) or snap fasteners (not shown), Pads 11, 1
It is also within the scope of the invention to attach 2 to back 16 or heel 17.

A third preferred embodiment of the present invention is shown in FIGS.
This is shown in FIG. In this embodiment, the shoe 70
Has a plurality of slip stoppers 71. Each non-slip has a plurality of small spikes 13. In this embodiment,
Shoes 70 designed for traditional golf spikes
Especially suitable for Such shoes are typically designed to accept traditional golf spike screw shafts,
It has a plurality of thread groove sockets 90. Each non-slip 71 has a similar threaded shaft 91 and is attached to a flange 92 having a plurality of small spikes 13.

As in the first and second preferred embodiments, the non-slip 71 is preferably made of an elastic polymeric material, most preferably polyurethane. Flange 9
Due to the resiliency of 2, when it is on an obstacle, it can be deformed and does not function as a lever arm to release the slipper from the shoe. The non-slip 71 tends to stay in the shoe when deformed, and regains its original shape when the obstacle is removed.

The size and shape of the small spike 13
Preferably, it is similar to the first and second preferred embodiments described above. Similarly, to minimize dimples, the thickness of the flange 92 is preferably the same as the thickness of the pads 11, 12 in the second preferred embodiment. Some known golf shoes have individual recesses (not shown) for the anti-skid 71, and in such shoes the thickness of the flange 92 is less important. As shown in FIG. 10, flange 92 is slightly concave on the side facing back 16 or heel 17. This allows
A better seal between the flange 92 and the back 16 or heel 17 is provided, preventing debris intrusion and providing tension to loosen the slipper 71 and reduce the likelihood of disengagement from the socket 91. .

The spacing between the miniature spikes 13 in the third preferred embodiment is also the same as in the first and second preferred embodiments. That is, the small spikes 13 should be far enough apart to prevent clogging. Preferably, the spacing of the small spikes 13 is about 2 to about 4 times the height of the small spikes 13, more preferably about 3 times the height of the small spikes 13. Therefore,
For small spikes 13 having a height of about 0.08 inches (about 2.0 mm), the spacing between the small spikes 13 is about 0.25.
Preferably it is inches (about 6.35 mm).

The first of the small spikes 13 of the non-slip 71
Is shown in FIG. A total of seventeen miniature spikes 13 are preferably distributed in a circular area of about 0.667 square inches (about 430 mm ² ).
To achieve the desired separation described above, a small spike 13
Disperse to maximize the distance between. In the illustrated dispersion, the outer ring of the eight mini-spikes 13 around the tip of the flange 92, the inner ring of the eight mini-spikes spaced inward from the first ring, and one There is a small central spike 13.

Small spike 13 in non-slip 71
A second preferred arrangement is shown in FIG. A total of 14 small spikes 13 are preferably about 0.667.
It is distributed over a circular area of square inches (about 430 mm ² ). In order to achieve the desired separation described above, dispersion is performed to maximize the distance between the small spikes 13. In the illustrated distribution, there are eight outer rings of miniature spikes 13 around the tip of flange 92 and six inner rings of miniature spikes spaced inwardly from the first ring.

As described above, although the lawn is not adversely affected,
Golf that provides the desired level of traction under as many different conditions as possible, resists departure from the shoe in which it is used, and causes less damage to pavements and floors than previously known systems It can be seen that a system is provided for providing traction in shoes (and other lawn sports).
