Description

[Detailed Description of the Invention] <<Industrial Application Field>> The present invention relates to a hook that is attached to the ceiling of a hospital room, operating room, etc., for suspending a hanger to which an Irligator is attached.

≪Conventional technology and problems≫ Conventionally, the hook part of the hook used to hang the hanger (hereinafter referred to as a hanger) from the ceiling to which Irligator etc. is attached to the lower end was formed by bending steel wire, and was used in hospital rooms and operating rooms. It was attached to the ceiling.

The hook has a shape that prevents the hung hanger from coming off easily, and since the base of the hook rotates at the center of rotation, the annular portion at the upper end of the hanger can be accurately connected to the base of the hook. The annular part cannot be locked unless it is positioned inside the hook from the front side of the
Furthermore, since the shape of the hook is complicated, it is difficult to hang and remove the hanger.

In addition, since the hook is located so that the base is at the center of rotation, only tensile stress acts on the base, so the base has considerable strength. It was also sometimes used to hang strings when committing suicide.

≪Purpose and structure of the present invention≫ The present invention is capable of reliably locking the annular portion at the upper end of the hanger from any direction of the hook, and when a load exceeding a predetermined value is applied to the hook, the hook The purpose of this project is to provide a hook for hanging a hanger that cannot be used for any purpose other than hanging the hanger due to damage. A hanging hook body made of synthetic resin, which has a hook portion consisting of a formed base and a semi-annular hanging portion formed below the base in a direction passing through the center of rotation, is attached to a base fixed to a ceiling surface. It is attached so that it can rotate freely.

≪Example≫ Examples will be described below based on the drawings.

In FIG. 1, reference numeral 1 indicates a base, and reference numeral 2 indicates a hanging hook body rotatably attached to the base 1.

The base 1 is made of a synthetic resin material, and has a mounting hole 12 on the upper surface of the small diameter cylinder 11, an annular step 14 on the lower end of the small diameter cylinder 11 and the upper end of the large diameter cylinder 13, and an outer peripheral surface of the lower end of the large diameter cylinder 13. An annular projection 15 is formed to project outward, and is fixed to the ceiling surface 10 with a fixing screw 17 via a washer 16.

The hanging hook body 2 is composed of a sheathing body 5 made of a synthetic resin material and having a hook portion 3 formed on its lower surface, and a rotating body 6 made of a synthetic resin material and screwed onto the sheathing body 5.

The hook portion 3 includes a base portion 31 located at a circumferential end portion away from the rotation center of the exterior body 5, and a semi-annular hanging portion 32 formed below the base portion 31 toward the rotation center direction. The exterior body 2 is arranged so that the end portion is located closer to the base 31 than the lowest end 33 of the hanging portion 32.
The upper end of the hanging part 32 projects toward the base 31 side with a predetermined distance from the lower surface of the lifting stop part 34.

The exterior body 5 includes a lower concealing portion 51 in which the hook portion 3 is integrally formed, and a side concealing portion 52, and a female screw portion 53 is formed on the inner surface of the side concealing portion 52.

The rotating body 6 consists of a threaded portion 61 with which the annular protrusion 15 of the large-diameter tube 13 contacts, and an upper surface portion 63 having an insertion hole 62 through which the upper portion of the small-diameter tube 11 projects upward. A lower annular protrusion 64 that contacts the annular stepped portion 14 is formed below the edge, and a male screw portion 65 corresponding to the female screw portion 53 is formed on the outer surface of the threaded portion 61 .

The present invention is constructed as described above, and is attached to the ceiling surface 10 in the following manner.

First, with the rotating body 6 fitted onto the base 1, the fixing screw 17 is attached to the ceiling surface 10 through the washer 16.
Fixed to.

Next, the exterior body 5 is screwed from below onto the rotary body 6, which is now rotatable on the base 1, to hide the base 1, the threaded portion 61 of the rotary body 6, etc.

In this state, the exterior body 5 is rotatable with respect to the base 1 together with the rotating body 6, and the hook portion 3
Since the base 31 of the hanger 4 is located at the end on the circumferential side away from the center of rotation of the exterior body 5, when the annular portion 41 of the hanger 4 comes into contact with the base 31 from the side and is pressed, the exterior body 5 rotates, and the front of the hook portion 3 is positioned within the annular portion 41, so that the hanger 4 can be hung easily.

In the embodiment, the hanging hook body 2 is composed of an exterior body 5 and a rotating body 6, but for example, as shown in FIG. It may be set to 2.

That is, in FIG. 3, there are two upper and lower annular engagement grooves 7 on the outer peripheral surface of the base 7 that tapers downward.
1 and 71 and a hook portion 8 formed on the lower surface thereof, annular engagement protrusions 91 and 91 that engage with the engagement grooves 71 and 71 are formed on the inner surface of the hanging hook body 9, and the base 7 After fixing to the ceiling surface with screws etc., the hanging hook body 9 is forcibly fitted onto the base 7 from below, and the engaging groove 7 is
1 and 71 and the engagement protrusions 71 and 91 are engaged with each other.

In this state, since the engaging groove 71 and the engaging protrusion 91 are each formed in an annular shape, the hanging hook body 9 can freely rotate on the base 7.

Moreover, when a load of more than a predetermined value is applied to the hook part 8,
Since the hanging hook body 9 is made of synthetic resin, the hook part 8 may be damaged or the engagement groove 71 and the engagement protrusion 91 may become disengaged, so it cannot be used for purposes other than hanging the hanger. There is no danger in using it.

<<Effects>> As described above, the present invention is such that the base of the hook is located at the end on the circumferential side away from the center of rotation, and the hanging hook body is rotatably attached to the base fixed to the ceiling surface. Therefore, no matter which direction the annular part of the hanger is brought into contact with the base of the hook, the hanging hook body rotates so that the front of the hook is located within the annular part, making it very easy to hang the hanger. be exposed.

In addition, since the hanging part is formed below the base in a direction that passes through the center of rotation, when a heavy object is suspended from the hanging part, bending stress is generated at the base, and the hanging hook is made of synthetic resin. Since the hanger is shaped like a body, if a load exceeding a predetermined weight is applied, the hook part or the hanging hook body will be damaged, and there is no danger at all even if the hanger is used for purposes other than hanging.
