Description

[Detailed description of the invention]

[0001]

[Industrial applications]

 The present invention relates to a screw such as a bolt used for attaching and fixing a member such as a panel member.

[0002]

[Prior art and problems]

 Conventionally, bolts and other screws are used to fix panel members in place, but these screws are used only for that purpose, and even when installing hangings etc. at the same place, separate screws are required. You have to attach it and hang a hanging object on it. Specifically, the inner wall members used in various facilities such as public halls and gymnasiums are often various panel members with specific dimensions, which are attached and fixed to concrete or frame by screws such as bolts to form the inner wall. , Exhibitions such as paintings and photographs may be hung on this inner wall and used as an exhibition space.

In this case, in order to hang an exhibit such as a painting or a photograph, a hooking member such as a locking screw or a hook is screwed into a panel member which is an inner wall, and a painting or a photograph is displayed on the panel member. . As described above, the mounting screws generally used in building members are used only for specific purposes such as fixing members, and when a brace fulcrum or a fixture for an exhibit is required on the member. Must be installed separately, even if the screw is near it. However, if the main body is a concrete member, a special connecting element such as an anchor bolt must be used, and a screw or a hooking device must be provided next to the screw, which is uneconomical and looks good. Is not good either. Also, for temporary wall members used at exhibitions, etc., the hooks for exhibition are attached at the beginning of the exhibition and removed when the exhibition is over, but the work is heavy.

[0004]

【Purpose】

 The present invention has been made in view of the above-mentioned problems, and by effectively utilizing the existing screws, it is easy to install the latch even on a concrete wall, and the required minimum number is required. It is an object of the present invention to provide a screw that can fix a panel member and lock an exhibit or the like with the screw.

[0005]

[Means to solve the problem]

 The gist of the present invention consists of a head portion and a tubular portion provided with a screw, and a screw hole is coaxially bored from the head portion toward the tubular portion, and the head portion is also provided in the screw hole. It is a screw characterized in that a screw having a portion is screwed. The screw may be any screw as long as it is composed of a tubular portion and a head portion, and a thread is threaded on the tubular portion.

The cylindrical portion is usually cylindrical, but a conical shape is also included in the cylinder. The head portion is formed at one end of the tubular portion and has a diameter larger than that of the tubular portion, and may be a hemispherical type, a hexagonal type, a dish type or the like. A so-called countersunk screw having a dish-shaped head portion and a conical cylindrical portion is also an object of the present invention.

Further, from the head portion toward the tubular portion, a screw hole is provided coaxially with the tubular portion. The screw thread may be formed in a part of the screw hole. A head screw having a head is screwed into the screw hole. The lead screw may be similar to the body. You may further provide a grandchild screw with respect to this child screw.

The child screw to be screwed is not particularly limited, but in the case of a countersunk screw, the shape of the opening of the screw hole is a mortar shape having a recess, and the screw is screwed into the screw hole. It is preferable that the head portion of the child screw is shaped so that the head portion of the child screw can be fitted flush with the dish-shaped head portion of the tubular portion. However, when a strong tightening force is required for the screw that is screwed into the drilled screw hole, it is better to leave the head of the screw that is screwed in protruding like a hexagon nut. .

Instead of forming a screw hole in the screw main body, a through hole may be formed through the main body as long as the strength such as tightening force and fixing force is not impaired.

[0010]

[Action]

 Since the present invention is configured as described above, for example, when the screw of the present invention is used for fixing a building panel, and when it is necessary to attach a brace or a hook to the panel, the panel is fixed. A screw that is unfolded from the existing screw and protruded to use it as a substitute for a hook, as a fulcrum for bracing or as a hooking tool, and even if there is a screw thread that can be engaged by removing the screw. Use by replacing the hook.

【Example】

 An embodiment of a screw according to the present invention will be described below with reference to the drawings. FIG. 1 is a partially cutaway perspective view showing a screw of the present invention, 1 is a screw of the present invention, and 2 is a screw thread. The engraved cylindrical portion, 3 are threads provided on the screw body 1, 4 is the head of the screw body, 5 is the opening of the flat head 4, and 6 is the screw 1 provided in the opening 5. A fitting groove that fits with a tool (driver) for rotating the tool, 7 is a screw hole formed on the same axis from the head 4 toward the tube 2, and 8 is provided on the peripheral wall of the hole 7. It is a female screw.

Reference numeral 9 is a recess surrounded by the opening 5 of the screw hole 7, and the recess 9 is a child screw 10 that is screwed into the screw hole 7 formed in the opening 5 of the screw 1. The head 11 is formed in a mortar shape so that it is flush with the upper surface 5 when fitted. Further, the screw shown in FIG. 2 is a perspective view showing a screw according to the present invention including a grandchild screw. Further, the screw shown in FIG. 3 is a perspective view showing the screw used when a strong tightening force is required.

FIG. 4 is a view showing one use state of the screw of the present invention, and FIG. 4 (a) shows a state where the hook 16 which is a hook member is screwed to the screw 1. An embedding nut 13 for screwing a screw into a concrete 12 such as a pillar of an object is embedded, and the screw 1 of the present invention for fixing a panel member 15 which becomes an inner wall 14 of a building to the embedding nut 13 is provided. The panel member 15 is screwed and fastened and fixed. Then, a hook 16 having a child screw is attached to the screw 1 of the present invention, which can be further screwed to the screw body, and the hook 16 and the hook metal fitting 17 of the painting 18 are connected to the wire 19. The painting 18 is displayed on the inner wall 14 by being connected with.

Further, FIG. 4B shows the state of the screw 1 after the display period of the painting 18 and the like has ended and the display 16 is removed, and the hook 16 which is a hook member is also removed. A child screw 10 is screwed into a hole 7 formed in the screw 1, serves as a plug of a recess 9 of the screw 1, and is fitted without protruding from the upper surface of the opening 5 of the screw 1.

[0015]

【effect】

 As described above, since the screw of the present invention is further screwed to the screw body, the screw is partially pulled out or removed, and a hook such as a hook is separately attached to the screw hole of the screw body. By screwing the members, it is possible to easily provide hooks for exhibitions such as paintings and photographs on the inner wall without using a separate screw or driving an anchor bolt.

Since the screw of the main body on which the hook member is screwed is a screw for fixing the panel member, it serves as an extremely strong fulcrum, so that the exhibit can be safely displayed regardless of whether it is light or heavy. It can be exhibited. This not only prevents damage to the exhibits due to falling, but also has an excellent effect on the safety of visitors.

Further, when the exhibition is finished, the hooking member can be easily removed by removing the hooking member and tightening the child screw, or by removing the hook screwed into the screw hole of the screw body. it can. Further, the wall body is not damaged, and the aesthetic appearance of the wall is not spoiled by using a child screw or attaching a decorative screw or a countersunk screw to the screw hole of the body.
