Description

  The present invention relates to a two-layer type shoe that can easily change the mounting position in four directions and exchange parts in order to use a favorite shoe for a long time.

Technical background

  Conventionally, there are shoes that can replace worn shoes for the purpose of wearing shoes for a long time and double-layered shoes.

  Patent Publication 2001-314206   Patent Publication Hei 10-085006

  The problem to be solved is that every time the shoe shoe is changed, the insole is replaced or the nail is reworked, and the shoe body is reworked to take unnecessary costs and effort.

  Therefore, it can be used as a standard product during shoe manufacturing or as a general-purpose replacement part, and after fixing the shoe to the bottom of the shoe, without changing the shoe body, changing the mounting position of only the lower part of the shoe heel or replacing the part Provide a two-layered shoe sneaker that only requires.

  The present invention relates to a double-layered shoe, in which a pair of large and small bevel gears in which the shafts intersect with each other at right angles in the hollow of the upper layer portion of the shoe shoe and the gears mesh with each other are installed, and the bevel gears whose shafts are vertical An internal thread is engraved in the large shaft, and the head is embedded in the lower part of the shoelace and connected to the fixed external thread. Then, in order to operate the operation of joining and separating the upper part of the shoelace and the lower part of the shoelace from the side surface of the upper layer part of the shoelace, a horizontal hole is penetrated through the side surface of the upper layer part of the shoelace, Insert the attached head.

  Furthermore, in order to change the mounting position of the shoe lower layer part in four directions and prevent the shoe lower layer part itself from spinning freely, the inner shape of the joint surface of the shoe upper layer part and the shoe lower layer part is a quadrangular prism surface. It is a kinematic pair and the outer shape is a cylinder.

  The shoe shoe upper layer is fixed to the sole of the shoe and can be used as a standard product for shoes production or as a general-purpose replacement part. It is easy to change and replace parts with a single screwdriver on the market.

  When the shoe lower layer part is reduced by one piece, it is possible to keep the worn state evenly by changing the mounting position of each of the left and right shoe shoe lower layer parts in four directions by 90. It is.

  In addition, the head with a small screw hole for replacing the lower part of the shoelace can be set on the chin part or the inner side of the upper part of the upper part of the shoelace that does not touch the ground, so there is little interference from the ground and it is hard to damage. In addition, the appearance is not impaired.

It is AA sectional drawing of FIG. 2, and the attachment imagination figure to shoes. It is a front view of the present invention. It is a top view of the present invention.

  The present invention is based on the condition that it is possible to easily change the mounting position and replace parts of the worn shoe lower layer part without changing the insole of the shoe body or hitting the nail each time the shoe shoe is replaced. Carried out.

  In a two-layer type shoe shoe, an appropriate quadrangular prism-shaped hollow is provided above and below the center portion of the shoe shoe upper layer (1), and one horizontal hole from the center is passed through an appropriate position on one side of the upper hollow. The head of the small bevel gear (4) with a screw hole in the head is installed in the upper hollow together with the small adjustment ring (6) so that it can be operated from the outside of the horizontal hole.

  Also, a large bevel gear (3) in which a suitable vertical hole is passed through the center of the upper layer portion (1) and a female screw is engraved in the shaft above the vertical hole is mutually connected to the small bevel gear (4). The gears are meshed so that their axes intersect at right angles, and the adjustment ring large (5) is inserted from below the vertical hole.

  Further, the shoelace lower layer portion (2) has a quadrangular prism shape with the center portion raised so as to form a face-to-face relationship with the lower surface of the center portion of the shoelace upper layer portion (1). The head of the square head male screw (7) is embedded and fixed in the center, and is connected to the female screw in the shaft of the large bevel gear (3) installed in the hollow of the upper layer portion (1) of the shoelace.

  Then, the screw of the small bevel gear (4) in which the joining operation and the separating operation of the shoe upper layer portion (1) and the shoe lower layer portion (2) are inserted into the horizontal hole on the side surface of the shoe upper layer portion (1). If the head with holes is tightened with a commercially available screwdriver, the shoe lower layer (2) is pulled up, and the joint is stabilized in combination with the pair of face pairs in the quadrangular prism shape with the shoe upper layer (1).

  The sole of the shoe and the upper layer (1) of the shoe can be fixed by an adhesive or screwing or nailing.

  Members such as a bevel gear and an adjustment ring may be made of metal or synthetic resin.

Claims (2)

In a two-layered shoelace fixed by a joining part such as a screw, a pair of large and small bevel gears in which the shafts intersect at right angles and the gears mesh with each other are installed in the hollow of the shoelace upper layer portion (1). At the same time, a female screw is engraved in the shaft of the large bevel gear (3) whose axis is vertical, and is connected to the male screw (7) which is embedded and fixed in the lower portion of the shoelace (2). In order to operate the joining operation and the separating operation of the upper shoe shoe upper layer portion (1) and the lower shoe shoe lower layer portion (2) from the side surface of the upper shoe shoe upper layer portion (1) above, A shoe shoe comprising a screw-headed head of a small bevel gear (4) inserted through a hole. The shoelace according to claim 1, characterized in that the inner shape of the joint surface of the shoelace upper layer portion (1) and the shoelace lower layer portion (2) is a quadrangular prism surface pair .
