Description

SHOE SOLE HAVING A PL~RALITY OF STUDS TH~EADEDLY
ATTACHED THERETO
BACKGROUND OF THE INVENTION
This invention relates to a shoe sole having a 5 plurality of studs attached thereto, more particularly to a shoe sole having a plurality of studs threadedly attached thereto.
Conventionally, a stud constuction shoe, especially a screw-in stud construction shoe, is provided with a plurality of screw-in studs on the sole thereof for increasing the ground-grasping force thereof.
Referring to Fig. lA, a conventional shoe sole 1 has a plurality of stud seats la formed thereon each of which has a threaded hole 2b formed therein and a plurality of radial ribs lb provided on the outer face of the stud seat la. A plurality of studs 3 are connected to the shoe sole 1 by screwing the threaded rod 3a fixed to said studs 3 in the stud seat la. Each of said studs 3 has a plurality of radial grooves 3c at one end face thereof. The radial grooves 3c are engaged with the radial ribs lb when the stud 3 is rotated by a wrench until said end face of said stud 3 abuts against the stud seat 3c. In addition, the threaded rod may be provided on the stud seat and the threaded hole may be provided on the stud for screw-coupling purposes, as best illustrated in Fig. lC. However, such a conventional shoe sole suffers from the following 2~2~3~

disadvantages:
~1) Because the studs are engaged with the shoe sole by the screw-coupling mechanism, the manufacturer can not exactly know the position where said studs are tightened to the stud seats on said shoe sole.
Therefore, each of the studs must be in the shape of a cylinder to ensure that all of said studs have the same figuration in all directions, although said studs may be triangular in cross section or elliptic in cross section in order to achieve an improved exercising performance in specific directions.
(2) Because of unavoidable errors in the manufacturing process, the end face of the stud 3 can not completely abut against the shoe sole 1, but contacts the stud seat la in a slightly inclined position, as best illustrated in Fig. lB. Therefore, the studs 3 are liable to become loose relative to the shoe sole.
(3) Moisture and/or water usually enters the shoe via a clearance, which is formed between the end face of the stud 3 and the stud seat la, and the threaded hole 2b.
(4) Referring to Figs. 2A, 2B, when a torsion force externally applied to said stud 3 exceeds a release torsion force (Pr), even though the stud 3 is applied by a tightening torsion force (Pf) to screw the threaded rod 3a into the threaded hole 2b, the stud 3 is liable to loosen because the effective safe range (Pp) is narrow (less than 15 degrees)~

2~2~391 ~--3----(5) Such a screw-coupling mechanism of the stud and the shoe sole can not provide a shock-absorbing effect.
SUMMARY OF THE INVENTION
It is therefore a main feature of this invention to provide a shoe sole having a plurality of studs threadedly connected thereto, wherein each of the studs can be securely attached to the shoe sole and prevented from moisture entering the shoe, as well as provide a shock-absorbing effect.
It is another feature of this invention to provide a shoe sole having a plurality of studs threadedly connected thereto, wherein said studs can be directional in cross section so as to reduce the forward resisting force thereof and increasing the backward ground-grasping force thereof during exercising, thus improving the exercising performance.
In accordance with this invention, the shoe sole has a plurality of studs, a plurality of stud seats for attachment of the studs to the shoe sole. Each of the studs has a first screw member and each of the stud seats has a second screw member provided therewith.
The first and second screw members are interengaged each other. An elastic disc is clamped between each of the stud seats and each of the studs. Therefore, each of the studs can be applied by a predetermined torsion to rotate so that the elastic disc can be snugly clamped between each of the studs and each of the stud -2~2~3~

seats. In this way, the studs can firmly and securely be attached to the stud seat of the shoe sole without any clearance formed therebetween, preventing moisture from entering the shoe. In addition, the elastic disc can provide a shock-absorbing effect to the shoe.
Moreover, the effective safe range of the rotation of the studs relative to the stud seats is wider than that of the conventional studs.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Referring to Figs. 4, 5, a first preferred embodiment of a shoe sole 10 includes six studs 30 threadedly connected thereto. The shoe sole 10 has six stud seats 11 integrally formed therein for attachment of the studs 30 to the shoe sole 10. Each of the stud seats 11 has a threaded hole 12 formed therein and a plurality of radial ribs 13 formed on an end face thereof. Each of the studs 30 has a threaded rod 31 .

2~2~391 connected thereto so that said stud 30 can be attached to the shoe sole 10 by screwing said threaded rod 31 into the threaded hole 12 of the stud seat 11. The stud 30 is in the shape of a cylinder. However, the stud 30 may be in the shape of a truncated cone which has a circular base and a vertex offset from an axis of said circular base, as shown in Fig. 6A; or elliptical in cross section, as shown in Fig. 6B; or generally triangular in cross section, as best illustrated in Fig. 6C; or in the shape of a cylinder having an end replaced by an inclined plane section relative to the other end thereof, as best illustrated in Fig. 6D. The abovementioned shapes of the stud 30 can be used in accordance with the different exercise requirements. A
plurality of radial grooves 33 are formed in the abutting face of the stud 30 in a conventional manner.
An elastic disc 20, which is made of polyurethane resin, has a diameter of 18 mm and a thickness of 2 mm.
The elastic disc 20 has a central hole 21 having a diameter of 4.7 mm formed therein. The elastic disc 20 is passed through by the threaded rod 31 of the stud 30 via the central hole 21 thereof and clamped between the stud 30 and the stud seat 11. The diameter of the threaded rod 31 of the stud 30 is slightly greater than that of the central hole 21 of the elastic disc 20 in order to increase the engaging force therebetween. The stud 30 can be rotated to a position where the elastic 2~2~9~

disc 20 is firmly clamped between said stud 30 and the stud seat 11 so that said stud 30 can be securely attached the shoe sole 10. In this position, the radial ribs 13 of the stud seat 11 and the radial grooves 33 of the stud 30 will respectively firmly engage with the opposite sides of the elastic disc 20, preventing the stud 30 and/or the elastic disc 20 from being rotated with respect to the shoe sole 10.
Referring now to Eigs. 3A, 3B, two diagrams of the relation between the torsion force and the rotating angle of the stud by the use of a rotating speed of 15 r.p.m. according to this invention are shown. It can be seen from the diagrams that when exercising, even though the stud 30 is applied by a release torsion force (Wr) which exceeds the tightening torsion force (Wf) and has a tendency of being loosened, the stud 30 can still be firmly attached to the shoe sole 10 within a relatively broad effective safe range (Pw). I'hat is to say, the stud 30 of this invention is allowed to be rotated at a larger angle by a release torsion force without the worry of being detached from the shoe sole 10 as opposed to the conventional stud. In addition, during exercise, by the use of the stud in the abovementioned shape of a truncated cone which has a circular base and a vertex offset from an axis of said circular base, elliptical in cross section, triangular in cross section, etc., the forward resistant force .. , ,- : ~

` 21~2~39~

relative to the ground which is exerted to the stud 30, can be reduced, and the backward ground-grasping force relative to the ground can be increase. Moreover, the studs of this invention can be rotated without worrying about the separation of said studs from the shoe sole, so as to adjust the proper direction thereof for either increasing the effective contact area between the shoe and the ground, as best illustrated as the solid line in Fig. 6E, or reducing the effective contact area between the shoe and the ground, as best illustrated as the phantom line in Fig. 6E.
Referring to Fig. 7, even though the stud 30 can not be vertically attached to the shoe sole 10, said stud can still be securely connected to ~he shoe sole 10 by the aid of the elastic disc 20.
It is noted that since the elastic disc 20 is firmly clamped between the stud 30 and the stud seat 11, serving as a water-seal, moisture is not allowed to enter the shoe. In addition, the elastic disc 20 can attribute a shock-absorbing effect to the shoe, thus preventing the user from injury during exercise.
With this invention thus explained, it is apparent that numerous modifications and variations can be made without departing from the scope and spirit of this invention. It is therefore intended that this invention be limited only as indicated in the appended claims.
