Description

string stopper

The present invention relates to a string stopper attached to a string-like body.

Conventionally, a rope fastener for fixing a rope (string-like body) to a handle is known (see Patent Document 1). The rope fastener has a body with two openings formed through the ends thereof and an abutment lug projecting from the upper surface between the ends of the body. A rope is passed through the two openings of the main body from one end side, the passed rope becomes a loop shape at the other end side of the main body, and the looped loop portion is wound around the handle. The abutment lug is hung by a loop portion wrapped around the handle. Thus, the rope fastener secures the rope to the handle.

U.S. Pat. No. 5,033,169

By the way, in the rope fastener described in Patent Document 1, since the loop portion of the rope passed from one end of the main body to the other end is hung on the abutment lug, the main body can be attached to the end of the shoelace, for example. However, it is not suitable for a mode of use in which the main body is passed between the portion of the shoelace extending in the lateral direction and the main body of the shoe and fixed at a predetermined position.

An object of the present invention is to provide a lace stopper that can fasten a string-like body such as a shoelace at a predetermined position.

The cord stopper of the present invention comprises a main body portion having an upper surface, a lower surface, and a tip end and a base end connecting the upper surface and the lower surface, and a protruding portion protruding from the base end in a direction opposite to the tip. A string attachment hole that opens at the proximal end is formed in the main body, and the protruding position of the protrusion is a position between the upper surface and the string attachment hole.
According to the string stopper of the present invention, the protruding portion protrudes from the position between the upper surface of the main body portion and the string attachment hole in the direction opposite to the tip of the main portion, so that the string attachment hole can be attached to the string attachment hole. By attaching the body and arranging the part of the string-like body to be hooked to the projecting part between the part of the string-like body and the projecting part, the string stopper is directed in the direction opposite to the tip of the main body part. The strap retainer can be held in place even when a pulling force is applied.

In the string stopper of the present invention, a projection dimension of the projecting portion in an insertion direction in which the tip end and the base end face each other may be smaller than the diameter dimension of the string attachment hole.
According to such a configuration, even if the diameter of the attachment hole is larger than the diameter of the string-like body to be attached to the attachment hole by the amount of play, the protrusion dimension of the protrusion is equal to the attachment hole. By making it smaller than the diameter of , it is possible to configure the protrusion so that it does not protrude excessively. can be suppressed.

In the string stopper of the present invention, the projecting portion and the string attachment hole may be spaced apart in a thickness direction in which the upper surface and the lower surface face each other.
According to such a configuration, since a space is provided between the projecting portion and the string-like body attached to the string attachment hole, other parts of the string-like body can be easily hung on the projecting portion. Therefore, for example, even if the string-like body is configured to be difficult to shrink in the radial direction, it is easy to hang the string-like body on the projecting portion, and the string-like body attached to the string attachment hole can be hung on the projecting portion. It is possible to reduce the risk of being pushed and bent by the string-like body.

In the string stopper of the present invention, the projection dimension of the projection in the insertion direction in which the tip end and the base end face each other is smaller than the diameter dimension of the string attachment hole, and the projection in the thickness direction is smaller than the diameter of the string attachment hole. A dimension between the string attachment hole may be smaller than a projection dimension of the projection in the insertion direction.
According to such a configuration, since the overlapping portions of the string-like body attached to the string attachment hole and hung on the projecting portion are in a positional relationship in which they crush each other, the portion of the string-like body hung on the projecting portion becomes the string. Unexpected detachment from the stopper can be suitably suppressed.

In the string stopper of the present invention, a continuous portion between the projecting portion and the proximal end may be formed in a concave curved surface.
According to such a configuration, the angle at which the protrusion and the base end intersect can be moderated by forming the continuous portion of the protrusion and the base end in a concave curved shape. Even if a directional force is applied, it is possible to suitably prevent the protrusion from breaking from the main body.

In the string stopper of the present invention, the protruding portion has a protruding side surface continuous with the base end and a protruding end surface continuous with the protruding side surface, and the corner portion where the protruding side surface and the protruding end surface are continuous is It may be chamfered.
According to such a configuration, it is possible to prevent the corner from being caught by the string when the string is hung on the projecting portion.

In the string stopper of the present invention, a corner portion between the side surface continuous with the upper surface and the upper surface may be chamfered.
According to such a configuration, for example, it becomes easier to insert and pass the lace stopper between the shoe body and the shoelace (lace-like body).

In the string stopper of the present invention, the body portion may be formed in a tapered shape as it goes from the base end side to the tip end side.
According to such a configuration, for example, it becomes easy to insert and pass the lace stopper between the shoe body and the shoelace (lace-like body).

In the string stopper of the present invention, at least the distal end side portion of the upper surface is formed of an inclined surface that is inclined with respect to the insertion direction in which the distal end and the proximal end face each other. The position on the distal side may be arranged below the position on the proximal side.
According to such a configuration, the lace stopper can be tapered in the thickness direction of the lace stopper, and for example, the strap stopper can be inserted and passed between the shoe body and the shoelace (lace-like body). becomes easier.

In the string stopper of the present invention, an inclination angle of the inclined surface with respect to the insertion direction may be 45° or less.
According to such a configuration, for example, the lace stopper can be easily inserted between the shoe body and the shoelace (lace-like body).

In the string stopper of the present invention, the inclination angle of the inclined surface with respect to the insertion direction may be 10° or more and 30° or less.
With such a configuration, by setting the inclination angle to 30° or less, it is possible to increase the area of the inclined surface on the upper surface of the main body. The string stopper can be inserted more easily between them.
Further, by setting the inclination angle to 10° or more, the length dimension in the insertion direction of the string stopper becomes excessively large in order to obtain a predetermined thickness dimension in the thickness direction in which the upper surface and the lower surface of the main body face each other. can be prevented from becoming

In the string stopper of the present invention, the lower surface may be formed flat along the insertion direction in which the tip end and the base end face each other.
With such a configuration, for example, when the lace stopper is passed between the shoe body and the shoelace (lace-like body), the lace stopper can be arranged along the shoe body.

In the string stopper of the present invention, two string attachment holes may be formed in the main body.
