Description

[Detailed description of the invention] Industrial application field The present invention relates to a hanger rail that guides and runs a hanging door car with hanging doors, etc., and in particular, the invention relates to a hanger rail that is attached to an appropriate number of hanging rods hanging from an upper part such as a ceiling. This invention relates to a hanger rail that will be constructed.

Conventional technology A hanger rail that has been used in the past has a lip channel steel cross section with an open groove on the lower surface, and is held by a bracket having a similar cross-sectional shape, and the bracket is suspended from a ceiling, etc. It was constructed by welding to hanging rods.

Problems that the invention aims to solve According to conventional methods, the hanger rail is held in advance with a required number of brackets, and the brackets at both ends are attached by welding to the hanging rod. In the former case, at least two workers were required to hold the ganga rail horizontally, and in the latter case, Although these can be operated by one person, they each have their own disadvantages, such as requiring a large area to be inserted through the bracket at the end.

Moreover, the installation height of the hanger rail is often determined by the length of the hanging rod or the situation such as the ceiling, and it is impossible to adjust the height for each hanging rod. It was difficult to erect it horizontally.

Further, since the brackets hold the hanger rail, the brackets are exposed at intervals on the sides and bottom, which is unsightly.

Means for Solving the Problems Therefore, the present invention aims to provide a hanger rail that can be easily and accurately erected. and a male screw 3 screwed onto the hanging rod 1.
A presser nut 4 screwed onto the male screw 3, a press plate 6 inserted through the hanging rod 1 and pressed downward by the presser nut 4, and a female screw 8 screwed onto the male screw 3 in the center are provided. A support body 7 having an engaging portion 9 formed on its upper surface, a hook-shaped portion 11 that is engaged with the engaging portion 9 of the support body 7 on the upper side, and a running portion 13 of a wheel 12 on the lower side with the hook-shaped portion 11. It consists of two rail members 10 formed on the same side.

Function: A hanging rod 1 is rotatably suspended from a frame 2 above a ceiling or the like at a required interval, and a retaining nut 4 and a support 7 are screwed onto the male screw 3 of the hanging rod 1, and a screw is inserted between the two. With the pressing plate 6 interposed, the hook-shaped portions 11 of the two rail materials 10 are locked to the engaging portions 9 of the support body 7,
By operating the presser nut 4 and pressing the pressing plate 6 downward, the hook-shaped portion 11 is held between the pressing plate 6 and the support body 7, and one hanger rail is formed by the two rail members 10. That is to say.

The height of the hanger rail is adjusted by rotating the hanging rod 1 before tightening the holding nut 4.

Embodiment Hereinafter, an embodiment of the present invention will be demonstrated. Reference numeral 1 denotes a hanging rod rotatably suspended from a frame 2 above the ceiling, etc., and a male screw 3 is screwed into the hanging rod. 4 is male thread 3
A pressing plate 6 having a hole 5 formed in the center thereof is inserted into the hanging rod 1 below by a pressing nut screwed onto the holding nut.
Reference numeral 7 denotes a support body having a female screw 8 screwed onto the male screw 3 at the center thereof and concave engaging portions 9 formed on the upper surfaces of both sides thereof, and is screwed onto the lower side of the pressing plate 6. Reference numeral 10 indicates a hook-shaped portion 1 that is engaged with the engaging portion 9 of the support body 7 above.
1, and the running part 13 of the wheel 12 is formed on the same side as the lower hook-shaped part 11.
The book rail materials 10 are arranged facing each other to form a hanger rail. 14 is a nut that fixes the hanging rod 1 to the frame 2, and 15 is a cover that closes the upper space between the two attached rail members 10.

In the case of this embodiment, the hanging rod 1 is directly attached to the frame 2 such as the ceiling, and the width of the support 7 and the position of the engaging part 9 are set to constitute a predetermined hanger rail. As shown in the third figure, a hanging member 16 may be fixed to a frame 2 such as a ceiling, and the hanging rod 1 may be rotatably attached to this. In addition, the width of the support body 7 is narrowed, the engaging part 9 is made into an inclined surface that becomes narrower at the bottom, and a pressing part that extends along the inclined surface is provided on the lower surface of the pressing plate 6, so that the pressing part and the inclined surface are connected to each other. A method may also be adopted in which a predetermined hanger rail is constructed by sandwiching the hook-shaped portion 11 of the rail material 10 between them.

Effects of the invention As mentioned above, the present invention is composed of two rail members 10, and the rail members are attached from both sides to the support 7 which is screwed to the hanging rod 1 hanging from the upper frame 2 in advance. The installation work can be carried out extremely easily by locking the rail material 10, and since the rail material 10 is about half the weight of conventional products, it can be easily carried out by one worker. By doing so, the position of the support body 7 can be adjusted in the vertical direction, and the rail installation position can be made accurate regardless of the state of the upper frame 2. In addition, the two rail materials are fixed to the support body 7 using the holding nuts 4, and can be installed without the need for welding as in the conventional method, which is convenient for maintenance after construction. Moreover, since it is not held by a bracket as in conventional products, it has various effects such as making the side and bottom surfaces of the attachment part less unsightly, and is useful in practice.
