Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a multi-joint band, and in particular, to elastically connects a plurality of joint members so that they can be bent and deformed in any direction with moderation, so that the present invention can be used in a band for a watch or the like. Regarding the multi-jointed band.

Conventionally, flexible materials such as lead have been used as materials that can be bent and deformed in any direction, but using lead as a watch band, for example, has the drawbacks of high cost and weight. Furthermore, there were some design problems, making it difficult to put it into practical use. Further, conventional watch bands, especially those made of leather, are difficult for physically handicapped or visually impaired people to attach and detach from their wrists.

In addition, conventional bangles, ankle rings, etc. are ring-shaped, so
The operation was troublesome because the device had to be inserted from the tip of the finger or ankle and moved to the desired area.

The present invention has been made in order to eliminate the drawbacks of the prior art described above, and its purpose is to enable bending and deformation of a plurality of joints in any direction with moderation and elasticity. By elastically connecting at least one core material that is pulled and tensed in one direction by the parts, it is possible to perform a strong gripping action with a simple operation (1), and this also makes it easier to hold hands and eyes. The aim is to provide an articulated band that can be easily installed and used even by people with disabilities. Another object is to enable these members to be removably attached to a variety of objects by using them as support bands for stationery, toys, and a wide variety of other items. Another object of the present invention is to use the present invention for bracelets, ankle rings, etc., so that bracelets, ankle rings, etc. can be easily attached to arms or legs. Another purpose is to make the grooves formed in the multiple joint members expand in a fan shape toward the outer periphery so that they are not visible from the outside during use, and to improve the design by applying color to the multiple joint members. Our goal is to provide good bands. Still another object is to improve durability so that it can withstand semi-permanent use by using a hardened steel spring material as the core material.

In short, the present invention provides a plurality of joint members having a surface shape that engages with each other with moderation and in which grooves are formed that expand in a fan shape toward the outer periphery, and the plurality of joint members are formed inside the joint member so as to communicate with the grooves. The joint members are elastically connected by at least one core member that is inserted through a hole and pulled and tensed in one direction by an elastic portion, and each joint member is configured to bend and deform with moderation in an arbitrary direction. It is characterized by the fact that

The present invention will be explained below based on embodiments shown in the drawings. The multi-joint band 1 according to the present invention includes a plurality of joint members 2 and a core member 3 that connects these joint members. In the embodiment, the joint member 2 is formed into a cylindrical shape, and as shown in FIG.
A groove 2a that expands into a fan shape is formed by an edge 2b on the left and right sides in the figure.
It is formed leaving behind. Further, a cut surface 2c cut in an arc shape along the axial direction is formed on the outer peripheral surface of the joint member 2 facing the groove, and a hole 2d communicating with the groove 2a is formed in the cut surface. has been done. Further, the outer circumferential surface of the joint member 2 is knurled to form an uneven portion 2e.

The core material 3 is made of, for example, a spring material of hardened steel, and has a coil-shaped elastic portion 3a formed in the center thereof.

Also, the linear part 3b of the core material 3 is inserted into the hole 2d of the joint member 2, and the diameter of the crest hole is υ compared to the linear part 3b.
If they are set sufficiently large, a gap is formed between them.

What is shown in FIGS. 1 and 2 is an example in which the multi-joint band 1 according to the present invention is used as a band for a watch 5. As shown in FIG. A retaining portion 5t that can engage with the uneven portion 2e of the joint member 2 is formed on the surface, and a hollow chamber 5c that can accommodate the elastic portion 3a of the core member 3 in the main body 5a. Holes 5d communicating with the hollow chambers and the retaining portions 5b are formed, respectively.

When attaching the plurality of joint members 2 to the main body 5a of the watch 5, first the elastic portion 3a of the core material 3 is attached to the hollow chamber 5 of the main body 5a.
At the same time, the linear portion 3b of the core material 3 is inserted into the hole 5d and taken out to the outside. Next, insert the groove 2a of the joint member 2 into the main body 5a.
is placed facing the engaging portion 5b of the cut surface 2c.
is arranged so as to face the groove 2a of the next joint member 2. By repeating the steps 5- above, the plurality of joint members 2 are assembled into the main body 5a of the watch 5.
The linear portion 3b of the core material 3 is inserted into the hole 2d of each joint member 2, and both left and right ends of the core material 3 are engaged with the cut surface 2c of the joint member 2 located at the rearmost position. The linear part 3b of the core material 3 is connected to the elastic part 3a of the stop member 6 formed in a cylindrical shape.
The elastic portion is pulled in the direction of the elastic portion and held in tension.

In this way, the plurality of joint members 2 are connected to the main body 5a of the watch 5.
It is configured so that it can be bent and deformed with moderation in any direction.

The present invention is constructed as described above, and its operation will be explained below. IIi of the core material 3 inserted into the joint member 20 hole 2d and the crest hole! Since a gap is formed between the joint member 2 and the shaped portion 3b, and a groove 2a is formed in the joint member 2 with a fan-shaped angle θ, each joint member 2 is opened by an amount corresponding to the fan-shaped angle θ. can rotate with respect to the adjacent joint members 2, and although the rotation angle of each joint member is small, when a large number of joint members 2 are connected as shown in FIG. As shown in the figure, a circularly curved multi-jointed band 1 can be obtained. As a result, it can be wrapped around the wrist as a band for the watch 5 as shown in FIG.

Moreover, the gripping force of the multi-joint band 2 is
Since each joint member 2 is pulled together by a, it is strong, and since the concave and convex portions 2e are engaged with each other in a moderate manner, the state of use can be maintained reliably. In addition, the installation and removal operations are extremely easy, and even physically handicapped people with hand or visual impairments can easily use the installation and removal operations.

Further, the plurality of joint members 2 have a good appearance in terms of design because the grooves 2a are not visible from the outside during use, as shown in FIG. In addition, by applying appropriate colors to the joint members,
The design of the multi-joint band 1 becomes even better. Furthermore, since a hardened steel spring material is used for the core material 3, it has extremely good durability and can withstand semi-permanent use.

What is shown in FIGS. 6 and 7 is another example of the use of the multi-joint band 1, and what is shown in FIG. In the state shown in FIG. 7, the multi-joint band 1 is wound around a suitable support member 7 and is used for mounting.

In addition, the articulated band 1 is not limited to the band for the watch 5, but can be used as a support band for stationery and toys, and can be attached to various objects. Furthermore, if used as a bangle or ankle bracelet, it can be placed on the target arm or leg immediately, and its uses are wide-ranging.

Incidentally, as shown in FIG. 4, hook portions 11 and 12 may be provided on the stop members 10 disposed at both ends of the core material 3, respectively, and these hook portions may be locked with each other. Further, as shown in FIG. 5, the core material 3 has an elastic part 3c formed at one end or both ends, and the elastic part is inserted into the hollow member 13.
It may be configured to be locked to the stop member 14. Further, the joint member 2 is not limited to a circular cross section, but may have a hexagonal cross section or any other suitable polygonal cross section as long as moderation can be obtained. Furthermore, by appropriately changing the number of joint members 2, it is possible to change the size of the multi-joint band 1. Further, the number of core members 3 is not limited to one, but may be two or more.

Since the wire of the present invention is constructed and operates as described above, the plurality of joint members can be bent and deformed in any direction with moderation, and the wire can be pulled and tensioned in one direction by the elastic portion. Since they are elastically connected by at least one core material, a strong gripping action can be achieved with simple operation, and the effect is that even hand- and visually-impaired people can easily install and use them. There is. Moreover, since it can be used as a support band for a wide variety of items such as stationery, toys, etc., these members can be detachably attached to various objects. Furthermore, since it can be used for bangles, ankle rings, etc., it has the effect of easily attaching bracelets and ankle rings to arms or legs. In addition, the grooves formed in the plurality of joint members by expanding into a fan shape toward the outer periphery are not visible from the outside during use, and appropriate colors are applied to the joint members with a count of 9.1. This has the effect of providing a band with a good design.
