Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a hook device for detachably attaching a swing to a children's horizontal bar.

Conventional technology Conventionally, in order to attach a swing to a children's horizontal bar, the mounting bracket was fixed to the horizontal bar with bolts or nuts, or the mounting bracket was hook-shaped, and an auxiliary hook made of synthetic resin with elasticity was added inside. Prepare,
This auxiliary hook was used to grip the iron bar.

Problems that the invention aims to solve However, with the former method, it is time-consuming to attach and detach the swing, and in particular, with the folding type horizontal bar, troublesome attachment and detachment operations are required each time it is assembled and stored.

In addition, although the latter method has the advantage of being easy to attach and detach from the iron rod, there is a potential risk of it coming off the iron rod due to an unexpected load.

Means for Solving the Problems Therefore, the present invention aims to provide a hook device which adds a locking mechanism to the iron bar grasping method using an auxiliary hook and prevents the hook from coming off the iron bar. , a hook main body 1 equipped with an auxiliary hook 3 made of an elastic synthetic resin material or the like on the inside, and a pivot support 5 below the hook main body 1, which swings between the opening 6 of the hook main body 1 and the back 7. a spring 8 for positioning the support piece 4 in the opening 6 of the hook main body 1; and a spring 8 attached to the side surface of the support piece 4 located in the opening 6,
It is composed of a side plate 9 that closes a space 10 below.

In order to attach the swing 13 to the iron rod 12, the opening 6 of the hook main body 1 is made to face the iron rod 12, and the support piece 4 and the side plate 9 are swung in the direction of the back 7 against the spring 8. The iron bar 12 is attached to the auxiliary hook 3 through the opening 6 and the space 10.
When the iron bar 12 is grasped, the support piece 4 and the side plate 9 are restored by the force of the spring 8, and the space 10 and the opening 6 are
occlude.

For removal, the support piece 4 and side plate 9 are swung toward the back 7, the iron bar 12 is removed from the auxiliary hook 3, and the space 10 and opening 6 are removed.

Embodiment Hereinafter, an embodiment of the present invention will be described with reference to the drawings. Reference numeral 1 denotes a hook body with a chain 2 connected to its lower end, and an auxiliary hook 3 made of an elastic synthetic resin material is provided inside the hook body. Reference numeral 4 denotes a U-shaped support piece that is pivoted 5 below the hook body 1, and is swingable between the opening 6 of the hook body 1 and the back 7, and is supported by a spring 8. It is located in Reference numeral 9 denotes side plates that are attached to both sides of the support piece 4 and close the space 10 below the auxiliary hook 3, and swing together with the support piece 4 to open and close the opening 6 and the space 10. Reference numeral 11 denotes an arcuate recess formed at the upper edge of the side plate 9, and is provided to correspond to the iron bar 12 gripped by the auxiliary hook 3. 13
is a swing.

Effects of the invention The invention is constructed as described above, and has three auxiliary hooks.
Since the space 10 below the iron bar 12 gripped by the side plate 9 is closed off by the side plate 9, this side plate 9 becomes an obstacle, and the separation of the iron rod 12 from the auxiliary hook 3 is completely prevented. Since it is attached to the support piece 4 and held in place by the spring 8, it is possible to swing safely without fear of unexpected swinging of the side plate 9. Furthermore, the support piece 4 and the side plate Since the hook 9 swings in the direction of the back 7 of the hook main body 1, various effects such as easy attachment and detachment to the iron bar 12 are achieved.
