Description

FIELD OF THE INVENTION
• The present invention relates to sole nails of soles, and particular to a steel nail of a sole which can reduce into a groove of the sole automatically and thus the steel nail will not destroy the ground or grasses on the ground. The steel nail generates a larger friction force to the ground so that the shoe has a preferred slide-proof effect.
BACKGSEMI-ROUND OF THE INVENTION
• In the prior art, a plurality of claws are integrally embedded into a sole. However, this will remove the earth so as to destroy the grass on the earth. However, this prior art is inhibited in golf field. If the shoes with these claws move on a hard ground, such as stone plates and tiles so that the user easily slides so as to fall to the ground.
• To improve above-mentioned prior art, an improvement is provided. Anassembly post1 withthread2 is placed in an integrally formedrubber claws3. A seat with threadedhole5 is integrally formed with alower sole6 and a middle sole is placed upon thelower sole6. The sole has a preferred ground fixing effect by installing therubber claws3. Thereby, the sole can reduce the affect of destroying the ground and grasses on the ground. However, this prior art has no steel nail to insert into the ground so that the fixing effect is not preferred. This is especially apparent in raining day. Moreover, this structure is made by rubber so that it is not rub-endurable.
SUMMARY OF THE INVENTION
• Accordingly, the primary object of the present invention is to provide a sole nail which comprises an assembly post having a plurality of rubber claws; the assembly post having a via hole forming an upper and a lower opening in the assembly post; a part of the assembly post having thread; an elastomer enclosing an periphery of the assembly post having thread; a steel nail passing through the via hole of the assembly post; an upper end of the elastomer resisting against a bottom of the steel nail; a seat having a screw hole penetrating through the seat; the seat being engaged into a lower sole of shoe; and a waterproof pad made of soft rubber; a bottom of the waterproof pad corresponding the steel nail being formed with a groove; an upper sole covering upon the waterproof pad. When the shoe dose not tread the ground, the groove of the waterproof pad will reduce the steel nail without protruding out of the bottom of the rubber claws; and when the shoe treads a soft ground, the soft upper sole and the waterproof pad will press the steel nail to protrude out of the soft rubber so as to be nailed into a soft ground.

DETAILED DESCRIPTION OF THE INVENTION
• In order that those skilled in the art can further understand the present invention, a description will be described in the following in details. However, these descriptions and the appended drawings are only used to cause those skilled in the art to understand the objects, features, and characteristics of the present invention, but not to be used to confine the scope and spirit of the present invention defined in the appended claims.
• With reference toFIGS. 3, 4 and5, the present invention comprises the following elements.
• Anassembly post10 has a plurality ofrubber claws13. Theassembly post10 has avia hole12 forming an upper and a lower opening (not shown) in theassembly post10. A part of theassembly post10 hasthread11.
• Anelastomer23 encloses a periphery of theassembly post10 having thethread11.
• Asteel nail22 passes through thevia hole12 of theassembly post10. An upper end of theelastomer23 resists against a bottom of thesteel nail22.
• Aseat20 has ascrew hole21 penetrating through theseat21. Theseat20 is engaged into a lower sole6 of shoe (not shown).
• Awaterproof pad30 is made of soft rubber. A bottom of thewaterproof pad30 corresponding thesteel nail22 is formed with agroove31. An upper sole7 covers upon thewaterproof pad30. When the shoe with the present invention dose not tread the ground, thegroove31 of thewaterproof pad30 will reduce thesteel nail22 without protruding out of the bottom of therubber claws13. When the shoe treads a soft ground, the soft upper sole7 and thewaterproof pad30 will press thesteel nail22 to protrude out of thesoft rubber13 so as to be nailed into a soft ground.
• Assembly of the present invention will be described herein. Theseat20 of the present invention is substantially combined with a lower sole6 of a shoe. Theassembly post10 having therubber claws13 is an integral body. Therefore, in assembly, the elastomer is assembled to theassembly post10. Then thesteel nail22 is inserted into thevia hole12 of the assembly post. Thereby, theassembly post10 with therubber claw13 is locked into theassembly post20. Thereby, theelastomer23 and thesteel nail22 are assembled therein and they are telescopic. The assembly work is simple. Thu the user can assemble the present invention by him or herself so as to assemble therubber claws13. Thereby, theelastomer23 and thesteel nail22 can be updated by himself or herself.
• In the present invention, thesteel nail22 can be not used.
• Moreover, as shown inFIGS. 7 and 8, thevia hole102 of theassembly post101 has a small-size lower end and a large-size upper end so as to receive theelastomer23 and thesteel nail22. However, this will have the same effect as above embodiment.
• Moreover, as shown inFIG. 9, anenhancing sheet32 can be installed in thegroove31 of thewaterproof pad30 and be above thesteel nail22 for buffering the impact force of thesteel nail22 so as to prevent thesteel nail22 to destroy thewaterproof pad30.
• Moreover, as shown inFIG. 10, in the present invention, theelastomer23,24 is a spring, or a cylindrical rubber so as to drive thesteel nail22 to move upwards or downward.
• Advantages of the present invention will be described herein. With reference toFIG. 5, when the sole leaves from the ground, no pressure is applied upon the upper sole7 and thewaterproof pad30 and thus thegroove31 of thewaterproof pad30 is not compressed. Therefore, thesteel nail22 can retract into thegroove31 so that the nail tip is not protruded from a bottom of therubber claws13. When the shoe treads upon the ground, as shown inFIG. 6, the press upon the soles will make the softwaterproof pad30 to be compressed and deformed so that thesteel nail22 descends. Namely, the tip of thesteel nail22 will protrude out from the bottom of therubber claws13. On the contrary, when the shoe leaves from the ground, thewaterproof pad30 will restore. By the elastic force of theelastomer23, thesteel nail22 will reduce automatically. Simply, thesteel nail22 of the present invention can reduce and protrude out automatically.
• Therefore, thesteel nail22 of the present invention can reduce automatically and thus thesteel nail22 will not destroy the ground or grasses on the ground. Thesteel nail22 generates a larger friction force to the ground so that the shoe has a preferred slide-proof effect. When the shoe treads upon a hard ground, thesteel nail22 can reduce into thegroove31, while therubber claws13 can fix the shoe on the ground. Thereby, the present invention is suitable to hard and soft ground.
• Furthermore, thewaterproof pad30 has the effect of preventing water from flowing into the shoe, which is not affected by the penetrating hole in theassembly post10 andseat20.
• The present invention is thus described, it will be obvious that the same may be varied in many ways. Such variations are not to be regarded as a departure from the spirit and scope of the present invention, and all such modifications as would be obvious to one skilled in the art are intended to be included within the scope of the following claims.
