Description

[Detailed description of the invention] [Industrial field of application] The present invention relates to a mounting bracket for an upper rail for a hanging door used at the entrance of a simple vinyl house, etc., and in particular, to firmly and stably mount and fix the rail. The present invention relates to mounting brackets with excellent practicality.

[Conventional technology and its problems]

BACKGROUND ART Hanging doors have conventionally been widely used as entry and exit doors in simple vinyl houses used for cultivating plants and the like. A hanging door is a sliding door that is suspended from two rollers that rotate within a long C-shaped steel top rail. It is attached perpendicularly, i.e. horizontally, to the aggregate (usually a pipe). Therefore, the installation involves assembling mounting brackets with a U-shaped cross section in a mutually interlocking manner with a C-shaped steel rail, and directly applying the bottom plate of the suspended rail to the upright structural aggregate pipe to be installed. Keep it in good condition and hang it around the pipe,
This is done by tightening nuts on both ends of the U-bolt that protrudes from the bottom plate of the mounting bracket. The connection and fixation using this mounting bracket is usually 4 to 5 times intersecting.
Done on the book pipe. Further, the U-bolt preferably has a folded portion formed in accordance with the cross-sectional shape of the structural aggregate pipe to be attached.

However, the problem with this mounting bracket is that when the hanging door is opened or closed and a force is applied to the door inward or upward or downward, the C-shaped steel rail tends to rotate. As a result, the fixation becomes loose and it easily becomes loose due to repetition of such operations.

Therefore, an object of the present invention is to provide an extremely practical mounting bracket that can firmly and stably fix the C-shaped steel upper rail of a hanging door without easily rattling.

[Means for solving problems]

In view of the above-mentioned circumstances, the inventors of the present invention have repeatedly researched prototypes of various mounting fittings, and as a result, have developed a practically excellent fitting.

In other words, the present invention provides C for hanging doors of simple houses, etc.
This is a metal fitting for attaching and fixing the shaped steel upper rail to the structural aggregate, and consists of a metal plate with a cross-sectional shape, U bolts, and nuts, and the C-shaped steel upper rail opens inward and engages in a suspended manner. The metal plate body to be mounted has its upper edge overhanging the rail abutting surface of the downwardly projecting overhanging plate portion by an amount substantially corresponding to the plate thickness of the upper rail. To provide an upper rail mounting bracket for a hanging door which has excellent mounting stability and has a pair of through holes for U-bolt insertion formed in its bottom plate.

The metal plate of the mounting bracket of the present invention is usually advantageously slightly wider than the thickness (diameter) of the pipe; for example, a bent plate with a width of about 5 to 8 cm wider than the pipe thickness is selected. used. The bottom plate portion is provided with a pair of through holes corresponding to the distance between the legs of a U bolt that is hung around the structural aggregate pipe.

In particular, the metal fitting of the present invention has an overhanging plate portion projecting downward integrally formed on the entire lower side of a metal plate having a cross-sectional shape, and the upper edge of the plate body being formed with the overhanging plate portion. From the above C-type steel rail contact surface,
It is distinctive in that it is formed to extend in an extended manner by an amount substantially corresponding to the thickness of the rail plate.

[Effect]

When the C-shaped steel upper rail is installed using the mounting bracket according to the present invention, the plate part extending downward at right angles is formed integrally with the lower edge of the metal plate bent in the cross-sectional shape. However, since the inner surface of the bottom plate of the C-shaped steel rail is pressed against the pipe side, the connection and fixation of the C-shaped steel is extremely stable, and therefore there is no risk of the rail rotating even when the hanging door is opened and closed over a long period of time. There is virtually no damage, and the life of the hanging door is significantly improved.

〔Example〕

Hereinafter, the metal fitting of the present invention will be explained in more detail with reference to the accompanying drawings.

FIG. 1 is a schematic side view viewed in the length direction of a rail showing an example of the mounting bracket of the present invention in use.

A metal plate body 1 having a cross-sectional shape is engaged with an elongated C-shaped steel upper rail 2 having a predetermined length at an appropriate position, and in a suspended state, a house structural aggregate pipe is attached. It is firmly connected and integrated with the pipe P by a U bolt 3 and a wing nut 4 at a predetermined upper position of the pipe P. The U-bolt 3 has its curved part wrapped around the pipe P, and its legs are inserted into a pair of through holes (not shown in the figure) formed in the bottom plate of the metal plate 1 for mounting. The metal fitting is inserted through the fitting, and is made to protrude from the outer surface of the bottom plate of the metal fitting, and is fixed by tightening the protruding tip portion with a thread with two wing nuts 4.

The metal plate body 1 according to the present invention has an overhanging plate portion 5 projecting downwardly formed integrally with the lower edge that engages with the C-shaped steel upper rail 2, and the upper edge thereof. Since the projecting plate part 5 is formed to extend from the surface by an amount corresponding to the thickness of the rail 2, the outer surface of the projecting board part 5 completely covers the inner surface part of the bottom plate part of the C-shaped rail 2. Can be pressed against the surface.
