Description

Key Wear

The present invention relates to a key wearing tool that allows a user to wear a key while carrying the key. Specifically, the present invention relates to a key wearing tool that allows a key to be worn on a wrist or ankle of a human body.

In a place where a user has a separate storage box for clothes or portable items, such as a public bath, a water park, or a sports center, the user can store the items in the storage box and carry a key to open and close the locker. Enjoy playing water or sports.

In carrying out such activities, it is inconvenient to carry the key and there is a risk of loss. Therefore, a key wearing tool having a key attached to a band that a user can wear on a wrist or ankle is utilized.

The key wearer is easily detachable by the user and is configured to adjust the length of the band in consideration of the difference in the size of the user's wrist or ankle. As an example of such a prior art band, FIGS. 15 and 16 There is a key fitting that employs the same band as shown in the photo.

The key wearing device of the prior art shown in Figure 15 is formed in the form of a spring on both ends of the main body 110 to which the key is attached, its length is extended as the tension force is applied in the longitudinal direction and the elastic band 120 is attached have. When the user wears the key to the wrist 120 or the ankle after extending the length by applying a tensile force to the band 120, the elastic retaining force of the band to maintain the state fitted to the wrist or ankle of the user.

However, in the case of prior art key fittings equipped with such spring-type bands, when the length of the band is made according to the average wrist or ankle size of an adult male, the wrist or ankle of a woman or child having a small wrist or ankle size There is a risk of loosening the key, and the key wearing port may be detached from the wrist or the like during the activity and the key may be lost.

Conversely, when the length of the band is made to fit a person with a small wrist or ankle, it is very inconvenient for the band to tighten the wrist or the like to a person with an average wrist or ankle size.

Moreover, as the key wearer is used for a long time, the elasticity of the band is lost so that the band becomes very loose or a part of the band is broken.

As another prior art key fastener, the key fastener 200 shown in FIG. 16 forms a band 210 of a shape in which the elliptical portion 211 is continuously attached, and in the middle of the continuous elliptical portions 211. The key attachment part 212 is provided, and the both ends of the band 210 are fixed to the panel 220 in which the number of a box, etc. are described.

Such a key wearing tool of FIG. 16 also has a problem in that it cannot be fitted to various sizes of wrists or wrists as in the key wearing tool of FIG. 15.

In addition, when the band 210 of the key fitting device applies a tensile force in the longitudinal direction of the band for the wearing, the length of the entire band is extended while the shape of the elliptical portion 211 is changed in the longitudinal direction of the band. Therefore, as the key wearer continues to use, when the tensile force to extend the length of the band is repeatedly applied, the shape of the elliptical portion 211 is changed in the direction in which the tensile force is applied, and the elastic force is lost. If a part is broken, the entire length of the band may be extended to lose its function as a band, and the key may be lost, and it may lead to theft.

The present invention in consideration of the problems of the key wearing device according to the prior art described above, the length of the band can be easily adjusted in accordance with the difference in the size of the user's wrist or ankle of the key wearing device and wearing the key wearing device such as wrist or ankle easily It is intended to provide a key fastener with a configuration that can be worn and removed in position.

In addition, the present invention can be changed according to the tension of the key wearing gear to be adjusted to the size of the user's wrist or ankle while the shape is changed or the length is increased by the application of repetitive tension force It is intended to provide a key fitting that does not lose the elastic force and does not lose the elastic force of the entire band or increase the length of the band even if a part of the band is broken by repeated use.

In accordance with the configuration and operation of the present invention, the user of the key wearer can only check the other end of the band which is not fixed to the main body when the band of the key wearer according to the present invention does not fit the size of his wrist or cuff. The length of the band can be tailored to its wrist or ankle size by pushing or pulling it in, and by the same operation it is possible to easily wear or take off the key fitting according to the present invention.

In particular, since the length of the band can be adjusted in a wide range as described above, even if the user of the key wearer has a small wrist, such as a child, or a very thick wrist, the key wearer of the present invention can be easily worn according to the user's wrist. can do.

A fixed end 80 is integrally formed at the end of the elastic band 60 opposite to the end at which the strap 50 is coupled. The fixing end 80 is formed with two fixing elements 81 for coupling the band 20 to the main body 20. These fixing elements 81 are formed to extend in a long manner so that the main lower case ( It is inserted into and fixed to the two through holes (28 of FIG. 8) of 25 (see FIG. 1). In addition, between these fixing elements 81, a key fixing portion 83 for fixing the key 10 is formed. The key fixing portion 83 extends long from the strap 50 side and is sequentially formed at the end thereof. The two engaging pieces (84 and 85 of FIG. 4) are formed, and the key 10 is fixed between these engaging pieces 84 and 85 (refer FIG. 1).

Next, the configuration of the main body 20 will be described with reference to FIGS. 7 and 8.

The upper case 21 and the lower case 25 are engaged with each other to form a main body 20, all of which are formed by injection molding an ABS resin, and in addition to the ABS resin, an injectable plastic material such as polypropylene, polyethylene, and polystyrene may be used. It can be formed by injection.

The upper case 21 and the lower case 25 are formed in a hollow shape such that the engagement spring (30 in FIG. 9) and the strap 50 of the band are inserted into the main body 20. Referring to FIG. 8, the lower case 25 has sidewalls 29 extending in the longitudinal direction, and the sidewalls 29 are formed in the upper case 21 in the longitudinal direction ( And the upper case 21 and the lower case 25 are engaged with each other, and a passage 26 is formed between these sidewalls, through which the strap 50 of the band is inserted (see FIG. 10). .

On the surface of the lower case 25 is formed a groove 27 in which the end of the engagement spring 30 is seated, and two fixing elements 81 formed in the fixing end 80 of the band are inserted and fixed (FIG. 1). The through hole 28 is formed.

Referring to FIG. 7, the outer surface of the upper case 51 has a surface 24 on which the key 10 is seated concave from the outer surface of the upper case, and the fixed end 80 of the band 20 is formed. The groove 23 into which the key fixing portion 83 of the fixed end is fitted is formed on the side of the longitudinal end to be engaged.

9, there is shown a perspective view of the engagement spring 30, which is an engagement means that engages with the

projections

51, 55 of the band strap 50 in the key wear opening of an embodiment of the present invention.

Engagement spring 30 is formed by the engaging portion 31 is inclined upwardly extending from the end 35, the both sides of the engaging portion 31 extends obliquely upward from the end 35 to the lower side and then extends downward again The two elastic support parts 33 are formed in a substantially semicircular shape as a whole. At the end of each elastic support 33 is provided with a curved surface 34 so as to slide while being supported in contact with the surface of the lower case 25 of the main body.

In this embodiment, the engagement spring 30 is integrally molded with a stainless steel sheet and formed as a leaf spring, but may be formed of any material having a large modulus of elasticity in addition to the stainless steel sheet.

As described above, each component constituting the key wearing tool according to the exemplary embodiment of the present invention has been described. Hereinafter, the operation of these components will be described with reference to FIGS. 10 to 14, 2, and 3. For reference, FIGS. 10 to 14 are enlarged views of a circle E portion in FIG. 10.

First, FIG. 10 shows a state in which one of the projections 51 of the strap is engaged with the engagement spring 30 mounted in the main body 20 while the strap 50 of the band is inserted into the main body 20.

Referring to FIG. 11, in this state, even if a tension force is applied to the band 20 by contacting the second surface 53 of the projection 51 of the strap with the end portion of the engagement portion 31 of the engagement spring, the strap 50 is applied. The main body 20 does not escape.

However, if the user applies a tensile force of some degree or more to the band 20 to increase the length of the band 40, as shown in FIG. 12, the direction in which the strap 50 is drawn out of the main body 20 (FIG. 10). The projection 51 of the strap strongly pushes the engagement portion 31 of the engagement spring 30 while the engagement portion 31 of the engagement spring 30 is pressed against the protrusion 51 of the strap. The projection 51 deforms in the opposite direction to the arrow 'F' by the reaction force applied.

The deformation of the protrusion 51 causes the second surface 53 of the protrusion 51 to be inclined, so that between the engaging portion 31 of the engagement spring 30 and the second surface 53 of the protrusion 51. As the engaged state is released, the strap 50 moves in the withdrawal direction from the main body 20.

When the strap 50 is moved, the engagement spring 30 is engaged with another protrusion 51 adjacent to the protrusion 51 where the engagement state with the engagement spring 30 is released, and when the force is continuously applied to the band, the protrusion 51 ), The strap 50 may be continuously drawn out of the main body 20.

Referring to FIG. 13, when the tensioning force is continuously applied to the band and the engagement spring 30 is engaged with the last protrusion of the strap 50, that is, the end protrusion 55 adjacent to the end of the strap 50, the tensioning force is applied to the band. Since the end protrusion 55 is not deformed, the engagement state between the end protrusion 55 and the engagement spring 30 is not released, and the strap 50 of the band is no longer drawn out of the main body 20.

When the user pushes the strap 50 in the direction of inserting the strap 50 into the main body 20 to reduce the length of the band 40 (the direction opposite to the arrow 'F'), as shown in FIG. The inclined first surface 52 of the engagement spring 30 presses the engagement portion 31 downward so that the engagement portion 31 is deformed downward so that the strap 50 is inserted into the main body 20. Will move.

As described above, the key wearing tool according to the present embodiment can adjust the length of the entire band 40 by a simple action of inserting or withdrawing the strap 50 of the band into the body 20, without the help of others The user can adjust the length of the band 40 according to the size of the user's wrist or ankle or other wearing position to wear the key fitting.

On the other hand, in the present embodiment, the elastic band portion 60 is provided in the band 40 of the key fitting, so that the length of the band 40 is elastic by the elastic band portion 60.

Referring back to Figures 2 and 3, Figure 2 shows a picture of a state in which no force is applied to the band according to an embodiment of the present invention, in which each band element of the elastic band portion 60 In 70, the large diameter part 71 and the small diameter part 72 hold | maintain semi-circle shape without any deformation | transformation.

When the band is pulled in this state, that is, when the tensile force is applied to the band 20, the semi-shaped form of the large diameter portion 71 and the small diameter portion 72 of the elastic band portion 60 is subjected to the tensile force as shown in FIG. It deforms in the shape of unfolding in the direction, and by this deformation, the length of the entire band is extended. However, if the tensile force is removed, it is restored to the state shown in FIG. 2 by the elastic restoring force of the band material.

Therefore, when the strap 50 is inserted into the main body 20, the length of the band 40 is adjusted to approximately the size of the user's wrist or ankle. When the band is fitted to a large hand or instep, the elastic band portion is elastically deformed and elongated so that the length of the band can be increased to easily wear the band.

On the other hand, without adjusting the length of the strap 50 is inserted into the main body 20, the strap 50 is attached to the main body 20 in a state where the key fastener is worn using the elastic deformation of the elastic band 60. The length of the band 20 can be adjusted to the wrist or ankle of the user by inserting or withdrawing it.

As such, the key wearing device according to the embodiment of the present invention described above can easily adjust the length of the strap, and on the other hand, the length of the band can be adjusted to the user's body size by the elastic band portion.

While the configuration and operation of the preferred embodiment of the present invention have been described above, the present invention is not limited to the configuration and operation of the embodiment, and various modifications and variations are possible within the scope of the appended claims, and such modifications and variations The configuration is within the scope of the present invention.
