Description

[Detailed Description of the Invention] The present invention relates to a shoe shape retaining device that is inserted into the upper of a shoe.

Conventionally, as a shape-retaining device inserted into the front part of the shoe,
One that uses a piece of cardboard or other material and bends it to fit the shape of the inner surface of the upper part, one that molds a piece of plate to fit the shape of the inner part of the upper part, one that uses air sacs, In addition, in order to be able to use the shape-retaining device to be inserted not only into the front part of the shoe but also into the entire upper part of the shoe, regardless of the size of the shoe, the front shape-retaining part 2 and the rear shape-retaining part of the shape-retaining device are used. 4 and 4 connected together via a spring material, etc. were used.

However, while a shape-retaining device for only the front instep can be used regardless of the shoe's left or right size or size, it does not preserve the shape of the rear instep, and shape-retaining devices for the entire instep are generally expensive to manufacture. It could not be said to be inexpensive, but it had the disadvantage of taking up a lot of space for storage and storage.

Therefore, the inventor of the present invention conducted various studies to improve the above-mentioned drawbacks, and as a result, he came up with the present invention.The present inventor formed a thin plate made of strong synthetic resin into a roughly shoe shape, and By providing the bellows part 6 in the shape-retaining part, the above-mentioned drawbacks can be improved, and it is lightweight.
To provide a shoe shape retaining device that is not bulky and inexpensive.

To explain the shoe shape retaining device of the present invention based on an example, as shown in FIGS. 1 and 2, a thin plate made of strong synthetic resin is integrally molded into a shoe shape, A hollow part 1 is provided, a reinforcing groove 3 is provided in the horizontal center of the front shape-retaining part 2, a back part 5 is provided in the center of the rear shape-retaining part 4, and a bellows part 6 is provided in the entire vertical center peripheral wall. It is.

The strong synthetic resin thin plate used in this invention is
It may be made of soft material such as vinyl chloride, and is not particularly limited, but transparent material is preferable.
This is because the shoe size, symbol, label, etc. affixed to the shoe upper can be seen while the shoe shape retainer is inserted into the shoe upper.

In the above embodiment, one reinforcing groove was provided in the front shape retaining part 2, but as shown in FIG. is not particularly limited.

Next, the method of using the shoe shape retaining device of the present invention will be described. First, the shoe shape retaining device 2 is inserted through the opening 9 of the shoe 8 until the tip of the front shape retaining portion 2 comes into contact with the tip inside the shoe upper.
At this time, since the reinforcing groove 3 is provided in the horizontal center of the front shape-retaining part 2, the front shape-retaining part 2 does not warp or warp.
It can be inserted smoothly without bending. After that, the rear end surface 7 of the rear shape retaining part 4 is inserted along the inner wall of the heel of the shoe. At this time, the rear shape preservation part 4
Since the bellows part 6 is provided on the entire circumferential wall at the vertical center, the rear end surface 7 can be freely bent back and forth and left and right for smooth insertion.After insertion, the elastic force of the synthetic resin allows the bellows part 6 to is restored and the rear end surface 7 comes into contact with the inner wall of the heel portion of the upper of the shoe, resulting in the state shown in FIG. 2.

In this way, the shoe shape retaining device of the present invention has a front shape retaining part 2.
Since the reinforcing groove 3 is provided in the lateral center of the front shape-retaining part 2, it can be inserted smoothly without warping or bending.

The shoe shape-retaining device of the present invention has the bellows part 6 on the entire vertical center peripheral wall of the rear shape-retaining part 4, so the rear end surface 7 can be freely bent back and forth and left and right.
Smooth insertion can be ensured regardless of the left or right side of the shoe or the size.

The shoe shape retaining device of this invention is made of strong synthetic resin.
A bellows part 6 is provided on the entire vertical center peripheral wall of the rear shape retaining part 4.
After insertion, the elastic force of the synthetic resin restores the bellows part 6, and the rear end surface 7 comes into contact with the inner wall of the heel part of the shoe upper, and each surface comes into contact with the inner wall of the shoe upper part. It is possible to achieve good shape retention.

Since the shoe shape retaining device of the present invention is provided with the hollow portion 1, the shoe shape retaining device can be stacked one on top of the other, and can be stored and stored without being bulky.

The shoe shape retaining device of the present invention has a back portion 5 provided at the center of the rear shape retaining portion 4 so that the back portion 5 protrudes from the opening 9 of the shoe when the shoe shape retaining device is inserted into the shoe upper. Therefore, when taking out the shoe shape retaining device from the shoe, the back part 5 can be pinched and the shoe shape retaining device can be easily taken out.
