Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a heel for women's shoes.

(Prior Art) Generally, a heel for women's shoes has a structure in which a replaceable heel is fixed to a grounded end face mainly for women's shoes.

For example, as shown in FIG. 3, a heel main body c in which a vertical hole b of a lower end opening is formed in a heel pillar a and a chrysanthemum cross section perpendicular to the axis are integrated by embedding the rear end of the axis d in a heel e. It comprises a heel main body f, and a shaft main body f of the heel main body f is pressed and inserted into a vertical hole b of the heel main body c to be fixed. Further, as shown in FIG. And a heel main body f in which one end of a male screw i is embedded and integrated in a heel e, and a male screw i of the heel main body f is screwed and fixed to a female screw h of the heel main body c. Etc. are known.

(Problems to be Solved by the Invention) In the former heel for women's shoes, the heel main body c and the heel main body f are connected very strongly, but the air sealed in the vertical hole b by the press fit of the shaft d at the time of connection. The heel main body c may be damaged by being compressed without escape, and if the heel e needs to be replaced due to wear, the bond is strong and the separation is difficult. In some cases, the heel main body c may separate from the shoe body. Furthermore, a new heel subject f
When press-fitting the shaft d, the vertical hole b becomes large and the connected state becomes unsatisfactory, so if you use one with a large shaft diameter or if you do not use a padding, you will not be able to firmly fix it and There is a drawback that things cannot be exchanged, and its solution is desired.

In the latter case, the heel for women's shoes has a structure in which the male screw i of the heel main body f is screwed into the preformed female screw h, and therefore the heel main body c and the heel main body f are connected at the time of initial connection and replacement. However, it is difficult to secure the directionality of the heel main body f with respect to the heel main body c, and there is a drawback that the coupled state is easily loosened.

The present invention solves the above-mentioned conventional drawbacks, and it is possible to relatively easily replace the heel main body even though it has a strong degree of connection, and moreover, firmly maintain the degree of connection between the heel main body and the heel main body after the replacement. The purpose is to provide a heel for women's shoes.

(Means for Solving the Problem) In order to achieve the above-mentioned object, the heel for women's shoes of the present invention has a synthetic resin heel main body in which a vertical hole with a lower end opening is formed in a heel column, and a sectional shape perpendicular to an axis. Substantially triangular shape (rice ball shape)
And a push-in screw having a wedge-shaped screw thread with a gentle slope facing toward the tip side of the screw thread slope. The screw is fixed by pressing it into the vertical hole of the synthetic resin heel body.

(Example) Next, an example of the heel for women's shoes of the present invention will be described with reference to the drawings.

1 is an exploded sectional view of a heel for women's shoes embodying the present invention, and FIG. 2 is an enlarged sectional view taken along the line AA of FIG. 1, in which a heel main body 1 made of ABS resin or the like and a heel are used. 6 is composed of a heel main body 7 made of urethane resin or the like.

In the heel main body 1, the heel column 2 is formed with a vertical hole 3 having a chamfered 3a and having a lower end opening.

The opening diameter of the vertical hole 3 is larger than the root diameter of the pushing screw 5 described later and smaller than the peak diameter, and the depth thereof is more than twice the opening diameter. The thickness of the heel column 2 is 2.5 to 3 times the opening diameter of the vertical hole 3.

The heel main body 7 is a rice ball shape whose cross section perpendicular to the axis is substantially triangular, and is fixed to the rear end of the push-in screw 5 having a wedge-shaped screw thread 4 in which the slope facing the tip side of the screw thread slope is made gentle. The seat plate 5b, which penetrates the hole 5a, is embedded and integrated in the heel 6 made of urethane resin or the like.

The push screw 5 is made of a material harder than the heel main body 1, for example, metal or hard resin.

When the heel main body 1 and the heel main body 7 regulate the directionality of the heel 6 of the heel main body 7 with respect to the heel main body 1 and press and insert the pushing screw 5 into the vertical hole 3 of the heel main body 1, the cross section has a substantially triangular shape. The maximum outer diameter portion of the wedge-shaped screw thread 4 having a rice ball shape partially expands the inner surface of the vertical hole 3 and the air in the vertical hole 3 is introduced while being discharged from the minimum outer diameter portion of the wedge-shaped screw thread 4. It comes to be combined in the state.

When the heel main body 7 is separated from the heel main body 1 and replaced, when the heel main body 7 is rotated with respect to the heel main body 1, the maximum outer diameter portion of the wedge-shaped screw thread 4 bites into the inner surface of the vertical hole 3 and the screw thread is inserted. The worn heel main body 7 is released while forming the ridge. When the new heel body 7 is attached to the heel body, the heel body 7 is fixed by pressing or screwing.

(Effects and effects of the device) The heel for women's shoes of the present invention has a synthetic resin heel main body in which a vertical hole at the lower end opening is formed in the heel column, and the cross-sectional shape perpendicular to the axis is approximately triangular (diaper shape). Also, the rear end portion of the push-in screw formed with a wedge-shaped screw thread with a gentle slope facing toward the tip side of the screw thread slope is configured with a heel main body integrally embedded in the heel, and the push-in screw mainly composed of the heel is composed as described above. Since it is configured to press and insert into the vertical hole of the resin heel main body, when the heel main body and the heel main body are combined, the direction of the heel main body with respect to the heel main body is regulated and the pushing screw is attached to the heel main body. When pressed and inserted into the vertical hole, the maximum outer diameter part of the wedge-shaped screw thread, which has a substantially triangular cross section, partially expands the inner surface of the vertical hole and discharges the air in the vertical hole from the minimum outer diameter part of the wedge-shaped screw thread. So that it will enter while being firmly connected in a wedge state Become.

Also, when exchanging the heel main body separately from the heel main body, if the heel main body is rotated with respect to the heel main body, the maximum outer diameter part of the wedge-shaped screw thread bites into the inner surface of the vertical hole and wears while forming a screw thread. The heel main body can be easily removed, and when a new heel main body is attached to the heel main body, if it is fixed by pressing or screwing, the elastic restoring force of the synthetic resin that constitutes the heel main body It is possible to firmly bond with each other without reducing the degree of bonding with each other.

Therefore, unlike the conventional case, the heel main body is not damaged by the air compressed and sealed by the press-fitting of the shaft at the time of connection,
Further, when the heel needs to be replaced due to wear of the heel, it is possible to separate relatively easily and quickly by rotating the heel as a main body although the connection is strong. The defect that the heel main body separates from the shoe body is eliminated.

In addition, since the new heel body is press-fitted or screwed into the elastically restored vertical hole, it is possible to maintain a strong connected state even after replacement, and use a shaft with a large shaft diameter as in the past, The inconvenience of using padding is eliminated.

Further, unlike the conventional structure in which a male screw mainly composed of a heel is screwed onto a preformed female screw, the female shoe heel of the present invention has a structure in which a female screw is formed by press-fitting and rotation, so that the coupling force is increased. Is strong and the bond does not loosen loosely, and the direction of the heel of the heel main body with respect to the heel main body is surely secured.

As described above, according to the present invention, it is possible to relatively easily replace the heel main body even though it has a strong degree of connection, and also to maintain the high degree of connection between the heel main body and the heel main body after the replacement. It is possible to provide a heel for women's shoes.
