Abstract

[Problem] A string fastener according to the present invention addresses the problem of enabling a string to be tied or untied by one touch. [Solution] This string fastener is characterized in having: lever units each having a lever head provided with two levers; a main body that accomodates the lever units from both sides; a pin that causes a string to branch inside the main body; a fixing/releasing bar that fixes or releases the lever unit to or from a lower unit disposed at the bottom of the main body; and a release button attached to the fixing/releasing bar through a coupler.

Description

Tie fastener

The present invention relates to a string fastener that can store a string.

Conventionally, when a shoe is worn, the shoe is fixed on the foot by tying the shoe, and the feeling of wearing the shoe is adjusted. It is inferred that there are many potential. This is not limited to shoelaces, but is considered a common issue in tying laces. On the other hand, as shoes that do not use a string, products that use a hook-and-loop fastener instead of a string and eliminate the trouble of tying the string have been commercialized.

In Japanese Patent Application Laid-Open No. 2004-016732, by winding the winding wire of the winding device, the shoelace can be tightened more securely by pulling the ring attached to the free end of the winding wire, and Although a technique relating to a winding device that can loosen a shoelace by unwinding the winding wire of the winding device and that is easy to put on and take off shoes is described, the winding operation is performed. It is necessary and cannot be tightened or loosened with a single touch.

For those having a structure for fastening or fixing by tying the string, it is desirable that the process of tying or unlocking is replaced with another method so that the complexity is eliminated.

Japanese Patent Laying-Open No. 2004-016732 (paragraph 0005, FIGS. 5 and 6)

An object of the string fastener of the present invention is to perform a one-touch operation to tie or untie a string.

The lever unit is fixed to a lever unit provided with two levers on a lever head, a main body that houses the lever unit from both sides, a pin that branches a string inside the main body, and a lower that is provided at the bottom of the main body. A fixing release bar to be released, and a release button attached to the fixing release bar via a connector.

A hook for preventing the lever from being detached from the main body is provided at the tip of the lever.

By providing an inclination to the lever of the lever unit, the space inside the main body can be used effectively.

By forming the tip of the lever into a concave shape, it is possible to prevent the string from being detached from the tip of the lever.

In the case of shoes, the strap can be routed and attached to the shoelace, the strap can be tightened by pushing the lever unit into the body, and the strap can be loosened by pressing the release button. It is possible to perform tightening or loosening, that is, tying or unfastening the string with one touch.

For example, even a physically handicapped person who can use only one hand can tighten or loosen the string with one hand if the strap fastener is attached to the shoe.

It is applicable not only to shoes but also to belts, bags, clothes, etc. that need to be loosened with a string.

The string fastener of the present invention will be described with reference to the drawings.

The main body 2 is a substantially rectangular parallelepiped having both sides and a bottom opened, and has a space for storing the lever 4 and an opening for inserting the lever 4 from both sides. Four string holes 18 for passing the string are provided. A button hole 17 for the release button 10 is provided on the top surface, and pins 9 for branching the strings are provided on both sides of the button hole 17 and inside the main body.
2 is a plan view of the main body of the example after insertion of the lever unit, FIG. 3 is a front view of the main body of the example of the present invention, FIG. 4 is a side view of the main body of the example of the present invention, and FIG. FIG. 8 is a side view of the main body showing the opening of the main body.

A fixing release bar 11 is formed symmetrically on the lower 8, and a hook 12 for fixing the lever unit 3 is provided at the tip of the fixing release bar. A release button 10 is provided on the upper surface of the fixing release bar 11 via a connector 13. Four string holes 18 may be provided in the lower 8.
5 is a bottom view of the main body of the example of the present invention, FIG. 6 is a front perspective view of the main body of the example of the present invention, FIG. 7 is a front view showing the configuration of the lower part, and FIG. It is a top view of a part.

The lever unit 3 is provided with two levers 4 in parallel at a certain interval on a substantially rectangular parallelepiped lever head 5, and on the bottom surface of the lever head, a hook groove for storing the hook 12 at the tip of the fixing release bar 11. 6 is provided. The fixing release bar 11 has a spring property because one end is connected to the lower 8, and when the release button is pressed, the fixing release bar 11 moves downward via the connector, and the hook 12 is detached from the hook groove 6, and the release button In a state where is not pushed, it returns to its original position, and the hook 12 enters the hook groove 6, and the lever unit 3 can be fixed and released. FIG. 1 is a plan view of an example of the main body before insertion of the lever unit, and FIG. 5 is a bottom view of the main body of the example of the present invention.

A claw 15 for preventing the lever unit 3 from being detached from the main body may be provided on the outer side of the distal end portion of the lever 4. In this case, it is desirable to provide a protrusion on which the claw 15 is hooked inside the main body 2. Further, by forming the distal end portion of the lever 4 in a concave shape, it is possible to prevent the string from coming off from the lever distal end portion when the lever unit 3 is pushed into the main body. Furthermore, the lever 4 can be tilted and attached to the lever head 5 so that the space inside the main body can be used effectively, and the tilt angle can be appropriately selected according to the shape and thickness of the string to be handled. it can. FIG. 12 is a plan view and a side view of an example of the lever unit.

紐 Join the lower 8 to which the coupler and release button are attached and the main body, and insert the lever unit 3 from both sides of the main body to complete the string fastener of the present invention. Before the lever unit 3 is inserted, the string is routed from the string hole 18 to the main body, and the lever unit 3 is inserted from both sides of the main body, whereby the string can be stored in the main body.

When the lever unit 3 is inserted into the main body, the string is hooked on the tip of the lever 4, the string is branched by the pin 9 in the main body, and the string is routed around the lever 4, so that the length of the lever is about 4 Double strings can be stored on one side only. On both sides, the amount of string storage is about 8 times the length of the lever.
10 is a plan view of the main body showing the path of the string, and FIG. 11 is a plan view of the main body showing the path of the string when the lever unit is inserted.

For example, in the case of shoes, the shoelace is routed to the main body in advance, and after the lever unit 3 is inserted, the shoelace is fastened and tied. When loosening the string, it was tightened by pressing the release button to release the hook 12 at the tip of the fixing release bar that was hooked in the groove on the bottom of the lever head of the lever unit 3 and removing the lever unit 3 from the main body. The string can be loosened. Next, when tightening the string, the lever head of the lever unit 3 is pushed into the main body, the string is stored in the main body, the hook 16 enters the hook groove 6 at the bottom of the lever head, and the lever unit is fixed. The string is also fixed. FIG. 13 is a perspective view of an example showing a state where the main body is mounted.

Once the shoelace has been routed to the main body, the operation of loosening or tightening the shoelace can be performed with one touch by pressing the lever unit 3 and the release button. As a result, even a disabled person who is physically disabled can tighten or loosen the shoelace if one hand can be used. In the case of healthy people, the convenience of putting on and taking off shoes is greatly improved.

The string fastener of the present invention can be industrially produced, and can be used not only in daily life, but also in fields where it is necessary to tighten or loosen with a string.
