Abstract
Description
Technical Field
[0001] The present invention relates to a cover for preventing sand from entering shoes when worn on shoes.
Background Art
[0002] In recent years, as tennis courts cause less burden on the knees during play and are easy to maintain, omnicoats with sand spread on the surface of artificial turf have become mainstream. When playing tennis on such omnicoats, a large amount of sand on the surface enters the shoes, and the sand in the shoes further spreads to the bare feet through the socks, which is very uncomfortable and also causes severe wear on the shoes and socks.
[0003] As a solution to such problems, Patent Document 1 discloses a shoe cover for playing tennis on an omnicoat. This shoe cover is provided with a sheet having a length such that the lower end is slightly above the bottom of the shoe below the belt fixed to the ankle, and the sheet covers the shoe to suppress the intrusion of sand.
[0004] However, the shoe cover described in Patent Document 1 has a sand intrusion of 20% or less compared to the case where the shoe cover is not worn as described in the embodiment, so it can be inferred that a certain amount of sand has entered the shoe. This is presumably because the sand that jumps up from the omnicoat enters through the gap between the lower end of the cover and the shoe and enters the shoe from the vamp or the opening of the shoe.
[0005] As a shoe sand prevention cover that solves the problems described in Patent Document 1, the invention described in Patent Document 2 is composed of a sheet body having a length from the front end of the vamp to the opening of the shoe to be worn and a width that reaches under both wings of the shoe upper, and on both side portions existing in at least any range from under both wings to near the edges of both wings in a state of being overlapped on the vamp, an inner cover provided with shielding members formed higher than other portions is provided, and a hook-and-loop fastener is attached to the heel portion, and it is characterized in that the heel portion is fastened with the hook-and-loop fastener. [Prior art documents] [Patent Documents]
[0006] [Patent Document 1] Japanese Patent Publication No. 2006-055601 [Patent Document 2] Japanese Patent Publication No. 2015-013022 [Overview of the project] [Problems that the invention aims to solve]
[0007] However, the invention described in Patent Document 2 had some drawbacks, such as the difficulty in securing the heel portion using the hook-and-loop fastener attached to the heel, and the fact that the hook-and-loop fastener itself could come undone during vigorous play, allowing sand to enter. [Means for solving the problem]
[0008] To solve the aforementioned problems, the shoe sand cover according to claim 1 is characterized by having a curved shape that covers the opening from the front end of the tongue of the shoe to the opening, having a length from the front end of the tongue of the shoe to the opening, and having a first hook-and-loop fastener on the right or left side; a curved shape that covers the opening from the heel of the shoe to the opening, having a length from the heel of the shoe to the opening, and having a second hook-and-loop fastener on the left or right side; a hook portion at the lower end of the front portion for attaching to the shoelaces of the shoe; a belt portion at the upper edges of the front portion and the back portion; a third hook-and-loop fastener portion at the lower edge connecting the front portion and the back portion; and a heel restraint portion at the center of the back portion. The invention according to claim 2 is the shoe sand cover according to claim 1, characterized in that the material of the heel restraint portion is an adhesive core or plastic. [Effects of the Invention]
[0009] According to the present invention, by replacing the hook-and-loop fastener on the heel with a heel retaining part, the shoes become easier to put on and take off. Furthermore, by tightening the third hook-and-loop fastener, the fit with the shoe is further enhanced, making it possible to completely prevent sand from entering the shoe even during vigorous play.

[Figure 7] This figure shows step S6 of attaching a shoe sand-preventing cover 1 according to Embodiment 1 of the present invention to a shoe 2. [Modes for carrying out the invention]
[0011] Embodiments of the present invention will be described below with reference to the attached drawings. The following embodiments are illustrative for explaining the present invention and are not intended to limit the present invention to these embodiments only. Furthermore, the present invention can be modified in various ways without departing from its essence. In addition, the same reference numerals are used for the same components in each drawing whenever possible, and redundant explanations are omitted.
[0012] First, the structure of the shoe sand-preventing cover 1 according to this embodiment is shown with reference to Figures 1 and 2. Figure 1 is a plan view of the shoe sand-preventing cover 1, and Figure 2 is a bottom view of the shoe sand-preventing cover 1. Figures 1 and 2 are for the right foot, and the left foot version is symmetrical. The following explanation will use Figures 1 and 2 for the right foot, but it is preferable to install both the left and right covers as a set.
[0013] As shown in Figures 1 and 2, the shoe sand-preventing cover 1 consists of a front part 11 and a back part 12, forming a single sheet. The front part 11 has a curved shape as shown in the figure, covering the front end of the tongue of the shoe 2 to be fitted, and has a length from the front end of the tongue to the opening. The first hook-and-loop fastener part 111 is located on the right side of the surface. The first hook-and-loop fastener part 111 is located on the right side of the surface as shown in the figure, and may have either a hook side or a loop side, or it may be located on the left side of the back, and may have a loop side or hook side opposite to the second hook-and-loop fastener part 122. In addition, although the first hook-and-loop fastener part 111 is shown as a key shape, its shape is not limited.
[0014] A hook portion 112 for attaching to the shoelaces of the shoe 2 is provided at the lower end of the front portion 11. A hook fixing portion 113 may be provided to accommodate the hook portion 112. The material of the hook fixing portion 113 is not specified.
[0015] The back portion 12 has a curved shape as shown in the figure, covering the back of the shoe 2, and has a length from the heel to the opening. The back portion 12 has a second hook-and-loop fastener portion 122 on the left side of the back surface. In the figure, the second hook-and-loop fastener portion 122 is positioned on the left side of the back surface as shown, and may have either a hook side or a loop side, or it may be on the right side of the front surface, and may have either a loop side or a hook side opposite to that of the first hook-and-loop fastener portion 111.
[0016] The front portion 11 and the upper edge of the back portion 12 are provided with belt portions 13. Since the belt portions 13 are for wrapping around and securing to the ankle, hook-and-loop fasteners may be provided at both ends, or, although not shown, belt adjusters may be provided.
[0017] On the lower side where the front face part 11 and the back face part 12 are connected, a third surface fastener part 14 is provided. The third surface fastener part 14 is attached with the attaching surface 141 and covers the shoe 2 without any gaps. The implementation method and its effects will be described later.
[0018] Also, at the center of the back face part 12, a heel pressing part 121 made of a hard material is provided. The material of the back face part 12 is not particularly defined as long as it is hard, and it may be an adhesive core or a plastic material, etc. <Example>
