Description

[Detailed description of the invention] [Technical field of the invention] This invention relates to an improvement of handcuffs for play.

[Prior art]

The conventional construction of this type of instrument is shown in FIG.

In this figure, 1A and 1B are metal ring-shaped parts that constitute the main body of the handcuff, and C-shaped bases 2A and 2
B and movable bodies 3A and 3B, the movable body 3
A, 3B are key holes 4 provided in the bases 2A, 2B.
It is configured to be inserted into the base bodies 2A, 2B by pushing a key (not shown) into the base body and rotating it.

Reference numerals 5A and 5B are connecting portions provided on the base bodies 2A and 2B, and 6 is a link that connects the pair of base bodies 2A and 2B. When using this for play,
Since the ring-shaped parts 1A and 1B, which are used like regular handcuffs, are made of metal, there is a risk of injuring the wrist, and if the key is lost, it will not be possible to remove it from the wrist, which is an undesirable problem as a play device. The game lacked entertainment and playability.

[Summary of the invention] This invention was made to eliminate the above-mentioned drawbacks, and by using plastic as the material of the ring, it eliminates the danger and also makes it easy to remove without a key. It is characterized by having a configuration that allows for.

[Example of idea]

An embodiment of this invention shown in FIGS. 2 to 4 will be described below.

In these figures, 7A and 7B are handcuff bodies, and as shown in FIG. 2, heart-shaped ring parts 8A and 8B, and a ring-shaped connecting part 5A integrally formed in a part of the ring parts. , 5B. In addition, the annular portions 8A and 8B are shown in FIG.
As shown in Figure 3, a cross-sectional view taken from the line,
An elastic member 1 composed of a metal core 9 and a plastic material 10 formed to surround this core.
1 is formed into a heart shape, and the dotted line in FIG. 2 indicates the core 9. Note that 5A and 5B are annular joints formed integrally with the plastic material 10 of the elastic member 11, and are configured in a ring shape. In addition, a pair of annular portions 8A shown in FIG.
8B are connected to each other by connecting appropriate ties or the like to the annular connecting portions 5A and 5B.

When using the handcuffs constructed in this way as a play tool, insert the wrist into the heart-shaped ring part 8B in the state shown at 12 in FIG. Rotate as shown at 13 in the figure to reach the handcuffed state. To remove it, rotate your wrist in the reverse order as above. In this case, the opening of the heart-shaped ring part 8B is set to be approximately equal to the dimension x when the wrist is in the 12 position as shown in FIG. However, since the annular portion 8B has a metal core 9 inside, it has sufficient elasticity and allows the wrist to be inserted easily and without causing any damage. If the tip 81B is processed or molded to have a rounded shape, it will be easier to insert and will not cause any damage to the wrist. Furthermore, since the annular joint 5B is integrally molded with the plastic material 10 of the annular part, if more force than necessary is applied to this part depending on the playing situation, the annular joint 5B will be removed.
Safety can be ensured by breaking and separating the ring from the annular portion 8B.

[Effect of idea]

Since this device is constructed as described above, it can be attached to and removed from the wrist without a key, and since it is molded from plastic, it will not cause any damage to the wrist. Furthermore, since the metal core is included in the plastic material, it has sufficient elasticity and has desirable properties as a play equipment.

[Brief explanation of the drawing]

Fig. 1 is a perspective view showing the conventional structure, Figs. 2 to 4 show an embodiment of this invention, Fig. 2 is a front view showing the structure of the handcuff body, and Fig. 3 is a perspective view showing the structure of the handcuff body. FIG. 4, which is a sectional view taken along the line in FIG. 4, is an explanatory diagram for explaining the procedure for attaching the handcuff body to the wrist. In the figure, 7A and 7B are handcuff bodies, 5A and 5B are annular joints, 9 is a metal core, and 10 is a plastic material. Note that the same reference numerals indicate the same or corresponding parts.
