Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a key wearing device that allows a user to wear and wear a key, and more particularly, to a key wearing device that is formed in a closed ring shape so that the key can be worn on a human body such as a wrist or ankle. It is about garments.

In places such as public baths, water parks, sports centers, etc. where users have individual cabinets for storing clothes and personal items, the user can open and close the locking device of the cabinet after storing personal items in the cabinet. Carry the key and enjoy bathing, playing in water, or playing sports.

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

Such a key wearing device is configured so that the user can easily attach/detach and adjust the length of the band in consideration of the difference in the size of the wrist or ankle of the user. An example of a band is a key garment that employs a band as illustrated in the photographs of FIGS.

The prior art key garment shown in FIG. 15 is constructed in the form of springs at both ends of the body 110 to which the key is attached, and the length thereof is extended by applying a pulling force in the length direction to make it elastic. A band 120 having a is attached. When the user wears the band 120 on the wrist or ankle after applying a tensile force to the band 120 to extend the length of the band, the elastic device of the band keeps the band worn on the wrist or ankle of the user. To do.

However, in the case of prior art keywear with such a spring-shaped band, if the length of the band is made to match the average wrist or ankle size of an adult male, the size of the wrist or ankle will increase. The wrists and ankles of women and children who are small in size become quite loose, and there is a concern that the key wearing equipment may come off the wrists and lose the key during the activity.

On the other hand, if the length of the band is tailored to a person with a small wrist or ankle size, it is very inconvenient for the person with a wrist or ankle size above average to tighten the wrist. is there.

In addition, the long-term use of such a key garment causes the band to lose elasticity, making the band very loose and causing a part of the band to be cut.

As another prior art key wear device, the key wear device 200 shown in FIG. 16 has a band 210 formed by continuously attaching oval parts 211 to form continuous oval parts. A key attachment portion 212 is provided in the middle of 211, and both ends of the band 210 are fixed to a panel 220 that describes cabinet numbers and the like.

Like the key wear device shown in FIG. 15, the key wear device of FIG. 16 has a problem that it cannot be fitted to wrists and wrists of various sizes.

In addition, when the band 210 of such a key garment is worn by applying a tensile force in the length direction of the band, the shape of the oval portion 211 changes in the length direction of the band. The overall length is extended. Therefore, if the pulling force for extending the length of the band is repeatedly applied by continuing to use the key wearing device, the shape of the oval portion 211 changes in the direction in which the pulling force is applied and the elastic force is increased. If it is lost and a part of the oval portion 211 is cut, the entire length of the band may be extended, the function of the band may be lost, and the key may be lost. ..

In consideration of the above-mentioned problems of the conventional key garment, the present invention allows the band length to be easily adjusted according to the size difference of the wrist or ankle of the user of the key garment. An object of the present invention is to provide a key garment having a structure in which the garment can be easily put on and taken off in a wearing position such as a wrist or ankle.

In addition, according to the present invention, the length of the band can be changed by pulling the band of the key garment so that the band can be adjusted according to the size of the user's wrist or ankle, but the shape thereof may be changed by the repeated application of tensile force. Provides a key garment that does not lose elasticity due to lengthening, and even if a part of the band is cut due to repeated use, the entire elasticity of the band is lost and the length of the band does not extend try to.

The above-described object of the present invention is to provide a main body to which a key is attached; and a band which is joined to the main body so as to form a closed ring with the main body and which is partially or entirely formed of a material capable of elastic deformation. The band includes one end fixedly coupled to the main body and the other end inserted into the main body, and the band has a plurality of protrusions formed along the length direction of the band from the other end. The main body is provided with meshing means made of a material that is elastically deformable by meshing with one or more of the protrusions, and each of the protrusions has a shape other than that of the band. When the end is moved in the direction of insertion into the main body, the first surface for elastically deforming the meshing means so that the meshing means and the protrusion do not mesh with each other and the other end of the band are moved in the direction of pulling out from the body. The second surface and the meshing means are provided with a second surface which meshes with the meshing means to prevent the band from moving, and when a predetermined force or more is applied in a direction of pulling out the other end of the band from the main body. This is achieved by a key garment that is elastically deformed so as to be disengaged from.

Without using the locker of the present invention, the other end of the band is inserted into the inside of the main body and one of the plurality of projections provided in the length direction of the band has the second surface of the main body. It meshes with the meshing means provided inside, but if the user pushes the band inside the main body according to the size of his wrist or ankle, the protrusion that meshed with the meshing means moves in the direction to push in the band Then, the meshing with the meshing means is released. Then, if the band is further pushed in, the second protrusions that are brought into contact with the disengaged protrusion will move beyond the meshing means while the second surface elastically deforms the meshing means.

When the user properly pushes the band against the body according to the size of his wrist or ankle and stops the pushing operation, the meshing means in the body of the band is between the two protrusions of the band. Like When the band moves in the pulling-out direction in this state, the second surface of the projection which is brought into contact with the meshing means in the pulling-out direction meshes with the meshing means to prevent the band from moving.

When the user tries to pull out the wearable article of the key of the present invention from his/her wrist or ankle, when the user pulls the band in the direction of pulling out from the main body, the second surface of the protrusion that is engaged with the engaging means is The protrusion is deformed while being applied with a tensile force, and the deformation causes the engagement between the second surface of the protrusion and the engaging means to be released, and the band is pulled in the direction of being pulled out from the main body, so that the user applies a tensile force to the band. By continuing to give it, the projection next to the one that has been disengaged releases the mesh with the engaging means by a similar action and the band is pulled out from the main body and its length is extended, so that the user can hold his wrist or ankle. It is possible to pull out from the band.

With the above-described structure and operation of the present invention, the user of the key garment may use the band other than the band that is not fixed to the main body when the band of the key garment according to the present invention does not fit the size of his wrist or ankle. The length of the band can be adjusted to the size of your wrist or ankle by simply pushing or pulling the end inside the body, and the same operation makes it easy to wear the key wearing device according to the present invention or You can take it off.

In particular, since the length of the band can be adjusted in such a wide range, the key of the present invention can be used even when the user of the key wearing device has a small wrist such as a child or when the wrist is very thick. It is possible to easily wear the wearing device according to the user's wrist or the like.

According to a specific embodiment of the present invention, the first surface of each protrusion is formed as an inclined surface that compresses the meshing means of the main body, and the second surface is formed as a surface perpendicular to the surface of the band. it can.

With such a configuration, when the band is moved in the direction of insertion into the main body, the meshing means of the main body does not block the movement of the band while being compressed and deformed by the inclined surface of the first surface of the protrusion, and the band is removed from the main body. When the band is moved in the pulling-out direction, the meshing means of the main body meshes with the vertical surface of the second surface of the protrusion to prevent the band from moving in the pulling-out direction.

Further, when a tensile force of a predetermined amount or more is applied in the pulling-out direction of the band, the projection is elastically deformed by this tensile force and the vertical surface of the second surface becomes an inclined surface which is inclined like the first surface. Therefore, the meshing between the meshing means and the second surface is released, and the band can move in the pull-out direction.

According to an additional embodiment of the present invention, the protrusion of the plurality of protrusions that is brought into contact with the other end of the band is not elastically deformed by the force greater than the predetermined amount in the direction of pulling out the other end of the band from the main body. It can also be configured to have a thickness.

According to such a configuration, after the protrusion that inserts the other end of the band into the inside of the main body and contacts the other end of the band moves beyond the meshing means inside the main body, pulling the band in the pulling direction The other protrusions are disengaged from the meshing means of the main body by a tensile force greater than a predetermined value, but the protrusions that are brought into contact with the other end of the band are not elastically deformed by a tensile force more than a predetermined amount, so they mesh with the meshing means. Is not released.

Therefore, the key wearing device according to the present embodiment does not cause the other end of the band to be completely pulled out and separated from the main body after the other end of the band is inserted inside the main body.

With such a configuration and operation, the key wearing device according to the present embodiment always maintains the state in which the body and the band are combined, so that the other end of the band is separated from the body and the user can It is very easy to use because you don't have to insert the other end of the band into the body to wear the garment, just push and pull the band.

According to an additional embodiment of the present invention, the engagement means comprises a support end supported on an inner surface of the body, the support end extending from the support end in a direction of inserting the other end of the band into the body. And a resilient support portion extending from the support end portion, the extended end portion being supported in sliding contact with the inner surface of the main body.

According to such an embodiment, since the meshing portion of the meshing means is extended in the direction in which the other end of the band is inserted into the main body, when the band is inserted into the main body, the first surface of the protrusion of the band holds down the meshing portion. The band can be inserted into the main body beyond the meshing portion, and when the band is pulled out from the main body, the end of the meshing portion comes into contact with the second surface of the protrusion to prevent the band from being pulled out.

Further, the meshing means is maintained inside the main body by having one end thereof supported on the inner surface of the main body and the other end supported on the inner surface of the main body by the end portion of the elastic support portion. Since the extended end portion of the elastic support portion is in sliding contact with the inner surface of the main body, elastic deformation of the meshing means due to the insertion of the band is smoothly performed.

According to still another aspect of the present invention, a wearer of a key of the present invention includes a main body to which a key is attached and a band coupled to the main body so as to form a closed ring with the main body. Is arranged so as to be perpendicular or inclined with respect to the length direction, and a connecting portion that connects between the deforming portion and the deforming portion that is deformed in a direction parallel to the length direction by a force that pulls the band is provided. An elastic band portion formed of a plurality of band elements formed of a material capable of being elastically deformed and provided in an alternating state, wherein the plurality of band elements are arranged in parallel with each other. Composed.

According to such a configuration of the present invention, when the user of the key wearing device of the present invention tries to wear the key wearing device on the wrist, ankle or the like, the elastic band of the band can be obtained by applying a tensile force to the band. For each band element that makes up the band, the elastic part deforms elastically in the direction parallel to the length direction of the band to expand the elastic band part and elastically expand the entire length of the band, making it easy for the user. A key garment can be worn on the band and the elastic restoring force of each band element causes the band to adhere to the user's wrist or ankle when the tensile force applied to the band is removed.

Further, since the elastic band part is constituted by a plurality of band elements arranged in parallel to each other in the key wearing device having the above-mentioned configuration, each band element should be formed thinner than the entire width of the band. It is possible that the band element can be very flexibly deformed by applying a tensile force to the band.

In particular, by using a band element having a diameter smaller than the entire width of the band or having a narrow width or thickness, the total deformation amount of the band element and the tensile force acting on the band are compared with the surface side of each band element. Since the stress acting on and the deformation rate become considerably small, the deformation of each band element and the band composed of band elements is performed fairly smoothly to increase the elasticity of the band, and then the band due to repeated deformation The cutting phenomenon due to permanent deformation and cracking of the material on the surface of the is prevented.

In addition, by arranging multiple band elements in parallel, even if one band element is cut, the overall shape of the band is not significantly deformed or the length is lengthened to minimize the appearance of the band. The aesthetics of are improved.

As an additional feature of the locker of the present invention in the form described above, the elastic band portion is composed of two band elements, and each of the band elements has a large diameter portion having a large diameter, and Small diameter portions having a smaller diameter than the large diameter portion are alternately arranged with respect to a center line extending in the length direction of the band, and the large diameter portion of any one band element and the other The small diameter portion of the band element can be configured by being arranged concentrically.

With such a configuration, by applying a tensile force to the band in the lengthwise direction, the large-diameter portion and the small-diameter portion of each band element are oriented in a direction in which they become parallel to the lengthwise direction of the band. It is deformed and the length of the band element is increased. However, since the large diameter portion and the small diameter portion of each of the two band elements are arranged concentrically with each other, even if the large diameter portion of one band element is deformed, the same shape as the deformed shape can be obtained. Since the small-diameter portion of the other band element is deformed, the band elements do not interfere with each other due to the shape deformation caused by the application of the tensile force.

In such a configuration, most of the large-diameter portion and the small-diameter portion function as a deforming portion of the band element, and the outermost portion of the large-diameter portion and the small-diameter portion of the band length when viewed in the width direction of the band. Since it is located in a position parallel to the direction, its shape is hardly deformed despite the application of tensile force in the length direction, and it functions as a connecting portion that connects the deformed portions of the band to each other.

Meanwhile, the connecting portions of the plurality of band elements are configured to be connected to each other at one point with the connecting portions that are in contact with each other.

With such a configuration, the plurality of band elements are connected to each other. However, when such a connecting position is provided in the connecting portion of the band elements, a plurality of band elements are elastically deformed when a tensile force is applied to the band. The fact that the band elements are connected to each other does not hinder the elastic deformation of the respective band elements.

Further, such a coupling between the band elements prevents a large change in the overall shape of the band even when any one of the band elements is permanently deformed or cut.

On the other hand, as one specific embodiment of the present invention, the key wearing device of the present invention is connected to the main body to which the key is attached and the main body and the main body so as to form a closed ring. And a deformable portion that is disposed so as to be perpendicular or inclined with respect to a length direction thereof and is deformed in a direction parallel to the length direction by a force pulling the band. A plurality of band elements, the elastic band portion including a plurality of band elements formed of a material that is elastically deformable and provided in a state in which connecting portions that connect between the deforming portions are alternately arranged; Are arranged parallel to each other, one end of the band is fixedly coupled to the main body, the other end is inserted into the main body, and the band has the other end according to the length direction of the band. A plurality of protrusions are formed, and an engagement means made of a material capable of elastically deforming by releasably engaging one or more protrusions among the protrusions is provided in the main body. Is a first surface that elastically deforms the meshing means so that the meshing means and the protrusion do not mesh with each other when the other end of the band is moved in a direction of being inserted into the main body, and the other end of the band is The second surface has a second surface that engages with the engagement means to prevent movement of the band when moved in a direction to pull out from the body, and applies a force more than a predetermined amount in a direction to pull out the other end of the band from the body. It can be configured by elastically deforming so that the meshing between the second surface and the meshing means is released.

According to such an embodiment, when the wearer of the key of the present invention is worn, the other end of the band is inserted into the body at an appropriate depth so that the length of the band is adjusted to the size of the user's wrist or ankle. Not only can it be worn in accordance with, but the band can be worn and removed more smoothly due to elastic deformation of the elastic band during the process of wearing or removing the band. However, the elastic force of the elastic band portion allows the band to be in close contact with the user's wrist or ankle.

As an additional embodiment of the present invention, on the other end side of the band, a key fixing part to which the key is coupled is provided extending in the length direction of the band, and the key fixing part is the main body. The key is connected to a groove provided at one end in the length direction, and the key is arranged on one surface of the main body in the length direction of the band.

According to such an additional configuration of the present invention, since the key is arranged on the one surface of the main body in the length direction of the band while being connected to the band, a separate configuration for attaching the band to the main body is provided. Need not be provided, and the key is placed in the length direction of the band, so that the key does not come into contact with the user's wrist or ankle and cause inconvenience to the user.

As an additional embodiment of the present invention, the band is formed with a hole to which an anti-theft device can be attached. With such a configuration, it is possible to prevent the user from returning the key and the wearing tool of the key to the operator.

FIG. 1 is a photograph showing a simplified and overall structure of a lock wearing device according to an embodiment of the present invention.

Referring to FIG. 1, the wearer of the key according to the present embodiment includes a body 20 on which the key 10 is seated and a band 40 which is connected to the body 20 at both ends thereof and is worn on the wrist or ankle of the user of the key. It is configured.

The two fixing elements 81 of the fixed end portion 80 of the band 40 are inserted into and fixed to the body 20 so that one end is fixed to the body 20 and the strap 50 constituting the band 20 is inserted into the body 20 and coupled. As a result, the band 40 and the main body 20 form a closed curve.

Although the band 40 always remains connected to the main body 20 when the wearable device of the present embodiment is used, the band 40 in the non-bonded state to the main body 20 will be described in order to explain the structure of the band of the present embodiment. The configuration of the band will be described with reference to FIGS. 2 to 6.

The band 40 of the present embodiment includes a strap 50 extending straight, an elastic band portion 60 extending from one end of the strap 50, and a fixed end portion 80 provided at an end portion of the elastic band portion 60. ..

Such a band 40 does not need to be formed separately for each component, and can be formed by integrally injecting polyurethane or other elastically deformable material.

First, the structure of the strap 50 will be described. The strap 50 is formed by extending in a straight line, and a plurality of protrusions 51 are sequentially formed on one surface of the strap 50 according to the length direction.

Referring to FIG. 5, each protrusion 51 is formed of an oblique first surface 52 and a substantially vertical second surface 53. Referring to FIG. 6, the end protrusion 55 attracted to the end of the strap 50 has a vertical surface 56 which is formed vertically like the other protrusions 51, but on the opposite side of the vertical surface 56. Is formed with a large width so that the protrusion is not deformed and is not formed as an inclined surface and forms the end portion of the strap 50.

Further, when the elastic band portion 60 is examined with reference to FIG. 2, the elastic band portion is composed of two band elements 70, and these band elements 70 have a large diameter of a semicircle having a large diameter. The parts 71 and the semi-circular small-diameter parts 72 having a diameter smaller than the large-diameter part are alternately arranged so as to face each other with respect to the center line in the length direction of the band 40. The diameter portion 71 and the small diameter portion 72 of the other band element are concentric with each other, and the respective portions are arranged in a mutually parallel relationship.

Further, between the large diameter portions 71 of the band elements and the small diameter portions 72 of the other band elements arranged concentrically with the large diameter portion 71, the outermost side in the width direction of the elastic band portion 60 is provided. A large diameter portion 71 and a small diameter portion 72, which are arranged concentrically with each other, are connected to each other by forming a connecting portion (62 in FIG. 3).

The point where the connecting portion 62 is provided is a point (see FIG. 3) at which the band 20 does not deform when the shape of each band element 70 is deformed by applying a tensile force to the band 20. Even if the large-diameter portion 71 and the small-diameter portion 72 arranged concentrically with each other are connected to each other by such a connecting portion 62, elastic deformation of the stretchable band portion 60 and extension of the length thereof are not hindered.

Rather, the large diameter portion 71 and the small diameter portion 72, which are arranged concentrically with each other, are coupled to each other by such a connecting portion 62, so that the two band elements 70 do not separate from each other and do not separate from each other. The parallel state can be maintained, and in particular, even when a part of one band element 70 is cut or permanently deformed, the remaining part is joined by the other band element 70 by the connecting part 62. Since the elastic band portion 60 is elongated, it is possible to minimize the permanent deformation of the shape.

A circular fixing hole 63 is formed at the center of the elastic band portion 60 approximately in the lengthwise direction. The fixing hole 63 prevents the user from returning the key wearing device according to the present invention. The anti-theft element (not shown) of FIG.

A fixed end portion 80 is integrally formed at an end portion of the elastic band portion 60 opposite to the end portion to which the strap 50 is joined. Two fixing elements 81 for connecting the band 20 to the main body 20 are formed on the fixed end portion 80. The fixing elements 81 are formed to be elongated so that the lower case 25 of the main body can be secured. It is inserted and fixed in the two through holes (28 in FIG. 8) (see FIG. 1). Further, a key fixing portion 83 for fixing the key 10 is formed between the fixing elements 81. The key fixing portion 83 extends long from the strap 50 side and two pieces are sequentially provided at the ends thereof. The connecting pieces (84 and 85 in FIG. 4) are formed, and the key 10 is fixed between these connecting pieces 84 and 85 (see 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 the main body 20, which are all formed by injection molding of ABS resin. In addition to ABS resin, polypropylene, polyethylene, polystyrene, etc. It can be formed by injecting a plastic material that can be injected into.

The upper case 21 and the lower case 25 are formed in a hollow shape so that a meshing spring (30 in FIG. 9) and a strap 50 of the band can be inserted into the main body 20. Referring to FIG. 8, the lower case 25 has side walls 29 extending in the length direction thereof. The side walls 29 are formed in the upper case 21 in the length direction. The upper case 21 and the lower case 25 are engaged with each other (not shown) so that the upper case 21 and the lower case 25 are connected to each other to form a passage 26 in which the strap 50 of the band is inserted (see FIG. 10). ..

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

Referring to FIG. 7, a surface 24 on which the key 10 is seated is formed on an outer surface of the upper case 51 so as to be recessed from an outer surface of the upper case, and a fixed end portion 80 of the band 20 is coupled to the surface 24. A groove 23 in which the key fixing portion 83 of the fixed end is sandwiched is formed on the end side in the length direction.

Referring to FIG. 9, there is shown a perspective view of a meshing spring 30 which is meshing means for meshing with the protrusions 51 and 55 of the band strap 50 in the wearer of the key according to the embodiment of the present invention.

The meshing spring 30 is formed by extending an end portion 35 of the meshing portion 31 so that the meshing portion 31 is inclined upward, and both of the meshing portions 31 are extended from the end portion 35 so as to be inclined upward and then downward. Two elastic support portions 33 are formed that extend to the side and are formed in a generally semicircular shape. At the end of each elastic support portion 33, a curved surface 34 is provided so that the elastic support portion 33 can slide while being in contact with and supporting the surface of the lower case 25 of the main body.

In the present embodiment, the meshing spring 30 is integrally formed from a stainless steel plate to form a plate spring, but any material other than the stainless steel plate having a large elastic coefficient can be formed.

The components of the key wearing device according to the embodiment of the present invention have been described above, and the operation of the components will be described below with reference to FIGS. 10 to 14 and FIGS. 2 and 3. .. Incidentally, FIGS. 11 to 14 are enlarged views of the portion E of the circle in FIG.

First, FIG. 10 shows a state in which one of the protrusions 51 of the strap is meshed with the meshing spring 30 mounted in the main body 20 while the strap 50 of the band is inserted in the main body 20.

Referring to FIG. 11, in this state, even if the second surface 53 of the protrusion 51 of the strap comes into contact with the end of the meshing portion 31 of the meshing spring and a tensile force is applied to the band 20, the strap 50 does not come out of the main body 20.

However, when the user applies a certain amount of tensile force to the band 20 in order to extend the length of the band 40, as shown in FIG. 12, the strap 50 is pulled out from the main body 20 (indicated by the arrow in FIG. 10). The protrusion 51 of the strap is strongly pushed on the meshing portion 31 of the meshing spring 30 by being pulled in the F direction), and the protrusion 51 has an arrow “F” due to the reaction force applied to the strap protrusion 51 by the meshing portion 31 of the meshing spring 30. Is deformed in the opposite direction.

Due to such deformation of the protrusion 51, the second surface 53 of the protrusion 51 tilts, the meshing state between the meshing portion 31 of the meshing spring 30 and the second surface 53 of the protrusion 51 is released, and the strap 50 is removed from the main body 20. It will move in the pulling direction.

When the strap 50 moves, the mesh spring 30 meshes with another protrusion 51 that is brought into contact with the protrusion 51 that has been disengaged from the mesh spring 30. When the tension force is subsequently applied to the band, the protrusion 51 is deformed to cause the strap 50 to be deformed. It can be subsequently withdrawn from 20.

Referring to FIG. 13, if the meshing spring 30 meshes with the last protrusion of the strap 50, that is, the end protrusion 55 that is brought into contact with the end of the strap 50, the tensioning force is applied to the band even if the tensioning force is continuously applied to the band. Since the end protrusion 55 is not deformed, the meshing state between the end protrusion 55 and the mesh spring 30 is not released, and the strap 50 of the band is not pulled out from the main body 20 any more.

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

As described above, in the key wearing device according to the present embodiment, the entire length of the band 40 can be adjusted by a simple action such as inserting the strap 50 of the band into the main body 20 or pulling it out, so that it can be assisted by another person. Instead, 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 wearing device.

On the other hand, in the present embodiment, the band 40 of the wearer of the key is provided with the elastic band portion 60, and the elastic band portion 60 makes the length of the band 40 elastic.

Referring also to FIGS. 2 and 3, FIG. 2 shows a photograph of a band according to an exemplary embodiment of the present invention in which no force is applied to the band. The element 70 maintains the semicircular shape of the large diameter portion 71 and the small diameter portion 72 without any deformation.

When the band is pulled in this state, that is, when a tensile force is applied to the band 20, the semi-circular shape of the large diameter portion 71 and the small diameter portion 72 of the elastic band portion 60 has a tensile force as shown in FIG. Is deformed so as to be expanded in a given direction, and the entire length of the band is extended by such deformation. However, when the tensile force is removed, the elastic restoring force of the band material restores the state shown in FIG.

Accordingly, when the length of the strap 50 is adjusted to be inserted into the body 20 and the length of the band 40 is roughly adjusted to the size of the user's wrist or ankle, when wearing the key wearing device, the wrist is worn. When the band is sandwiched between the upper part of the hand or the part of the foot that is larger than the ankle, the elastic band part elastically deforms and extends, so that the length of the band increases and the band can be easily worn.

On the other hand, without adjusting the length of the strap 50 inserted into the main body 20, the elastic deformation of the elastic band portion 60 may be used to insert the strap 50 into the main body 20 while wearing the key wearing device. The length of the band 20 can be adjusted to the user's wrist or ankle by pulling it out.

As described above, the key wearing device according to the above-described embodiment of the present invention can easily adjust the length of the strap, and the elastic band portion allows the length of the band to be adjusted to the size of the user's body. You can
