(57) [Summary] [Purpose] In band-type keychains, the key locking mechanism, which has traditionally been difficult to manufacture, is solved, and the strength of the fused part of the key storage part and the band is reduced. The purpose is to prevent [Structure] The present invention is a key holder consisting of a key storage part and a band part fused to both ends of the key holder. A band type key that is fused and fixed to the end of a key storage part, a hole used for locking the key is bored in the remaining tip of the band, and a key locking piece is provided around the hole that is fused and reinforced. It provides a folder. [Effects] The key holder is easier to manufacture than conventional ones, and the fusion joint between the key storage part and the band is stronger.

Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention is suitable for use in saunas, health centers, pools, athletics, etc. Regarding band-type keychains, which are used to carry keys such as cars, etc., wrapped around the wrist like a wristwatch. It is something to do.

0002

[Conventional technology]

Traditionally, saunas, health centers, training gyms, pools, etc. Thermoplastic resin cloth band type keychain with locker key attached to arm band was used. The thermoplastic resin cloth band is preferably one with good drainage, so it is preferable to use a hydrophobic band. It is made of woven fabric made of hard and sturdy resin filaments. This band type key holder requires the key to be locked in the key storage section, and conventionally, A thermoplastic resin string was fused and fixed to the end of the storage compartment, and the key was locked with this string. In this case, when fixing the string by fusing the end of the band and the end of the key storage part, both A string was sandwiched between the two parts, and the three parts were ultrasonically fused at the same time. This operation is performed by three parties In addition to being difficult to operate, pinching the string reduces the strength of the fusion between the end of the band and the end of the storage compartment. becomes weaker.

0003

[Problem that the idea aims to solve]

This invention solves the difficulty of attaching the key locking string in the key storage section, and also The purpose is to make the connection between the storage part and the band strong.

0004

[Means to solve the problem]

In order to avoid the difficulty of simultaneous three-party fusing, the inventor of the present invention designed the end of the band part and the end of the key storage part. Usually, the end of the band is attached to the key holder to form a key locking piece by two-way fusion with the Place the end of the band where it will be fused and fixed to the end of the storage compartment, leaving the key locking piece intact. By welding and fixing the ends of the key storage and the key storage part, the difficulty in operability due to three-way welding and the welding The purpose of the present invention was achieved by preventing a decrease in strength.

[0005] That is, the present invention has a thermoplastic resin cloth key storage part and a key storage part that extends from both ends of the key storage part. A band-type keychain consisting of a thermoplastic resin cloth band with , fix one of the band parts to the key storage part leaving the end of the band remaining, and A key locking piece is made by drilling a hole in the hole and reinforcing the area around the hole by melting. This product provides a hand-held keychain. The present invention will be explained in more detail with reference to drawings of embodiments.

[0006] The band type keychain of the embodiment shown in Figure 1 is made of thermoplastic resin filament. Bands B and C are made of cloth and extend from both ends of key storage part A. Bands B and C can be fastened by wrapping them around the wrist in a known manner, for example, like a watch band. It looks like this. Also, as shown in Figure 5, band B may be shifted longer than the tip of band C to form an extension. A portion E is formed and fixed by a fused portion D.

[0007] A male hook-and-loop fastener 1 is provided on the extension part E, and an identical hook-and-loop fastener 1 is provided on both sides of the fused part D. A male hook-and-loop fastener 2 is provided. These hook-and-loop fasteners 1 and 2 are separated by the fused part D at the tip of the band C. The attached hook-and-loop tape is fused when band B and band C are fused and fixed. This is because part D was melted at the same time.

[0008] When using this band, put your wrist inside the ring of the band and attach the hook-and-loop fastener. Place the hook-and-loop fastener 1 and hook-and-loop fastener 2 tightly over the female hook-and-loop fastener 3 on the front side of band B. Let them wear it. In this case, since the extension E has some flexibility, it should not be placed on top of the hook-and-loop fastener 3. It can be firmly fixed.

[0009] In addition, since the hook-and-loop fastener 2 is also bonded on top of the hook-and-loop fastener 3, the hook-and-loop fastener 1 can strengthen the joints of In addition, the extension E of the band B has a waist, so it can be used even if exposed to water or hot water for a long period of time. Fastener 1 will not collapse. The band of this invention gets wet with water during use, so it is desirable that it drains well. Make sure the locker is dry before handing over the key chain to the next customer. is preferred, and therefore a hydrophobic material is required.

0010 For this reason, the hydrophobic resin tape used in this invention requires a sheet made of hydrophobic synthetic resin. For example, if the material is made of resin such as polyamide, polyester, or polypropylene, A cloth made of resin fiber can be used. The key storage part A can be used in any structure without any restrictions. For example, as shown in FIG. 1, the sheet 7 extending from the side edge of the base sheet 4 is Fold it over the key placed on top 4, cover it over the key, and then fold it over the key in the opposite direction. cover with the extended lid sheet 5, and attach the sheet 7 with the hook-and-loop fastener 6 provided thereon. A method that attaches to the hook-and-loop fastener (not shown) on the back of the key to hold the key. Any method can be used as appropriate.

[0011] The hook-and-loop fastener used in this invention is similar to what is commonly called Velcro tape. For example, one surface of a hook-and-loop fastener is made of hook-shaped hard fibers. There are hook-and-loop fasteners, such as those with loop-shaped fibers flocked to the other hook-and-loop fastener. Simply crimp one side of the snare to the other to engage and secure the other, then pull firmly with your fingers. Any device that has a locking surface structure that can be peeled off can be used. can.

0012 The present invention has a key storage part structure as shown in the embodiment of FIG. That is, a locking piece F is left at the end of the band B on the base sheet 4 of the key storage part A, The band B and the end of the base sheet are fixed by a fused portion 8. Fusion is any method that melts and fuses thermoplastic resin cloth with heat. However, because the band of this invention is thick, ultrasonic welding is difficult. Most suitable.

[0013] As shown in the cross-sectional view of Fig. 2, the key locking piece F that extends continuously from the band is It is fused and fixed to the edge of the board sheet 4, and its tip is free from the surface of the base sheet 4. ing. A hole G is made in the center of the key locking piece F, and the area around this hole G is protected by heat. It was partially melted and reinforced. Without this thermal reinforcement, the hole would loosen from the periphery and lose its shape. Place the key hole over this hole G, pass through the eyelet core, and compress the eyelet from both sides. Then, the key can be fixed in the hole G as shown in FIGS. 3 and 4. The keychain of this invention displays the locker number and barcode etc. You can attach what you have.

[0014]

[Effect of the idea]

The band of this invention attaches the key locking piece by fusing two pieces of cloth. Moreover, it does not reduce the strength of the fusion bond between the band and the key storage part, making it a durable key. - band can be provided.
