Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an improvement of a hanger for hanging drip bottles, etc. from the ceiling.

[Prior Art] A drip hanger in which the hook rotates freely before hanging the drip bottle, but does not rotate easily after hanging the drip bottle is known from Utility Model Application No. 61-165742. The hanger has a base that fixes it to the ceiling,
It consists of a cap screwed into the base, a hook passing through the cap, and a rotation regulating member provided inside the cap, and the rotation regulating member regulates the rotation of the hook when weight is applied to the hook.

[Problems to be Solved by the Invention] The above-mentioned known hanger has a good appearance because the fixing bolts are not exposed to the outside, but it cannot be fixed to the ceiling without removing the cap.
In addition, since it is fixed with one bolt, the fixation of the base tends to be unstable, and there is a risk that the base will rotate together with the hook, rendering the rotation regulating member useless. For the user, attaching and detaching the cap is also easy.
Since it is troublesome to fix the base to the ceiling so that it does not rotate with a single bolt, it is possible to mount the base to the ceiling so that it does not rotate without removing the cap, and the bolt is not exposed to the outside. A hanger was requested. The purpose of the present invention is to provide a drip hanger that can meet this demand.

[Means for Solving the Problems] In order to achieve the above object, the means adopted by the present invention include a base that is screwed to the ceiling etc., a cap that is screwed into the base, a hook that penetrates the cap, and a screw that is attached to the cap. In the drip hanger equipped with a rotation regulating member, the base is fixed to the ceiling etc. via two or more screws on the outside of the cap, and the hollow truncated cone-shaped cover with multiple claws formed on the inner periphery is inserted from below. The cap is placed over the base to cover the outer surface of the base, and the claws are inserted into the grooves between the base and the cap and fixed.

[Function] Since the base is fixed to the ceiling or the like with two or more screws, it is impossible for the base to rotate together with the hook hanging down from the cap after screwing the cap into the base. Furthermore, since this screw is located on the outside of the cap, there is no need to attach or detach the cap when attaching the base to a ceiling or the like. Furthermore, since the cover covering the screw is simply fitted by elastically fitting the claw into the groove between the base and the cap, installation is extremely easy.

[Example] The hanger of the present invention will be explained based on an example shown in the drawings. As shown in FIGS. 1 and 2, the base 11 of the hanger 10 is screwed to a fixed part such as a ceiling with three setscrews. The cylindrical upper part of the cap 12 is screwed into a cylindrical portion depending from the center of the base 11. The lower part of the cap 12 is conical and has a hole in the center through which the shaft of the hook 17 passes. A cylindrical recess 18 is provided in the upper part of the cap 12, and a rubber bush 16 is inserted into the recess 18.
is inserted into the bush, and the washer 15 is placed on top of the bush. The shaft of the hook 17 projects into the recess 18 and passes through the bush 16 and washer 15.
A ring 14 is fitted to the upper end of the shaft portion of the hook 17 to prevent the hook 17 from falling off. A cover 13 is fitted on the outer periphery of the base 11 to completely cover the outer surface of the base 11. The cover 13 has a conical surface that is continuous with the conical surface of the cap 12. A plurality of claws 19 are provided on the inner peripheral surface of the cover 13, and when the cover 13 is inserted into the cap 12 and pushed in, the claws fit into the grooves 20 between the base 11 and the cap 12, so that the cover 13 is fixed. Ru. The screws that fix the base 11 are also covered by the cover 13 and cannot be seen from below.

As shown in FIG. 3, the bush 16 is a hollow cylindrical body, and its inner radius r is the same as that of the hook 17 in FIG.
The radius of the shank is equal to or slightly less than. Further, the outer radius R of the bush 16 is the first
It is equal to or slightly larger than the inner radius of the recess 18 shown.

Before hanging the drip bottle on the hook 17, it is necessary to turn the hook 17 to an angle that makes it easy to hang the drip bottle, but when no load is applied to the hook 17, that is, when the bush 16 is not compressed, Since the frictional resistance between the shaft of the hook 17 and the inner surface of the bush 16 is small, the hook 17 can be turned easily.

When a drip bottle is hung from the hook 17 and a load is applied to the hook 17 in the direction of arrow W, the bush 16 is compressed by the load. The outer diameter of the bush 16 is equal to or slightly larger than the inner diameter of the recess 18, and the inner diameter is equal to or slightly smaller than the outer diameter of the shaft of the hook 17, so that when compressed, the outer radius expands. The friction between the inner surface of the bush 16 and the shank of the hook 17 increases because the inner radius not only tends to tighten but also shrinks the inner radius. As a result, the hook 17 becomes difficult to rotate, and even if the drip bottle is accidentally touched, the hook 17 will not turn, so there is no risk that the drip bottle will move during the drip.

[Effects of the invention] As mentioned above, the hanger of the present invention can be fixed to the ceiling with the cap attached to the base, unlike conventional hangers that require the cap to be attached and removed when fixing to the ceiling etc. Therefore, it is extremely easy to install the base on the ceiling, etc., and unlike the conventional case where the base was fixed with one bolt, which could cause the base to rotate with the hook, two or more bases can be attached. Since it is fixed to the ceiling etc. with screws, there is no risk of the base rotating with the hook. Furthermore, since the screw is covered with a cover, it has a good appearance, and the cover can be easily installed by simply pushing it in.
