Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to an overhead door in which a shutter for opening and closing a frontage opening is sent in horizontally to be housed when the opening is opened.

[Conventional technology]

Overhead doors are widely used as doors in factories, warehouses, etc. to open and close frontage openings. The conventional overhead door A has a fourth
As shown in the figure, it is composed of a shutter B, a guide rail C, and a hoisting mechanism D. That is, guide rails C consisting of a vertical rail 1 and a horizontal rail 2 are arranged in parallel on the indoor side at both ends of the frontage opening E. This guide rail C is attached to the mounting angle 3 along the pillar or wall surface on both sides of the frontage opening E.
A joint piece 4 and a vertical rail 1 which are horizontally projected from the top are fixed in a state where the upper part of the vertical rail 1 is slightly inclined toward the indoor side. On the other hand, near the ends of both horizontal rails 2, stoppers 5 are fixed respectively for making contact with the upper end of the shutter B when the shutter B is fed. The area where the guide grooves 2', 2' of the horizontal rail 2 face each other is used as a housing area for the shutter B. A reinforcing angle 6 is attached to the outside of the horizontal rail 2 and projects from the mounting angle 3 along the horizontal rail 2. Further, from the ceiling, four stays 7 are fixed vertically across the reinforcing angle 6 of the horizontal rail 2 to reinforce the horizontal rail 2.

Shutter B, which becomes the next door, is a thin panel 1 made of steel, aluminum, fiberglass, etc.
5, the upper and lower sides of the single unit in the longitudinal direction are connected to hinge 8
It is flexibly connected to the indoor side with the installation of . Rollers with built-in bearings are attached to both ends of the single panel 15, and are slidably fitted into the grooves of the guide rail C.

Furthermore, as a winding mechanism D for the shutter B, one end of each wire rope is fixed to both lower ends of the panel 15, and the other end is fixed to wire drums 9 arranged on both sides above the frontage opening E. A shaft 10, which is rotatable by the restoring force of a spring, is pivotally supported on both wire drums 9 at both ends thereof. 16 is a lighting fixture attached to the ceiling.

The overhead door A having the above configuration is operated as follows. Panel 15 at the bottom of the shutter
When you put your hand on it and push it up, the shaft 10 and the wire drum 9 rotate due to the pushing up force and the restoring force of the spring, and wind up the wire rope.
, and is fed into the horizontal rail 2 and stored in the shutter storage area. Conversely, to lower the shutter B, by pulling down the operating rope fixed to the lower part of the shutter (not shown), the shutter B moves from the horizontal rail 2 to the vertical rail 1 and closes the frontage opening E.

The above configuration is a manually balanced type, but there are also chain types that have a balanced chain hoist and operate a hand chain, and electric types that use a motor to rotate the shutter, but both of them are attached to the shaft. The spring's restoring force is used to balance the opening and closing of the shutter.

[Problem that the invention attempts to solve]

In the above conventional technology, in order to open the frontage opening,
After the shutter was raised almost vertically, it was sent to a horizontal rail and stowed away, so the back side of the shutter was exposed overhead, which did not look good on the outside.

In addition, the shutter storage area is an entrance and exit, and lighting equipment should be placed on the ceiling above it, but due to the structure of the overhead door, the shutter blocks the light distribution from the lighting equipment, so it is difficult to guide the shutter storage area. It is placed on the ceiling outside the rail. For this reason, sufficient illumination near the entrance and exit was not obtained at night, and the surrounding area was dark, which was not a favorable working situation.

[Means for solving problems]

This invention solves the above-mentioned problems, and even if the frontage opening is opened and the shutter is placed on a horizontal rail for storage, the storage state of the shutter is not visually noticeable, and the illuminance below the shutter storage area is improved. The object of the present invention is to provide a louvered overhead door. The specific means for this purpose was constructed as follows.

Both ends of the shutter, in which the panels are flexibly connected at the top and bottom, are fitted into guide rails consisting of vertical rails and horizontal rails arranged in parallel on both sides of the frontage opening, and the shutter is attached to the horizontal rails along the guide rails. In the overhead door that is sent to and stored in the horizontal rail, a louver covering the entire surface of the storage area is installed below the storage area of the shutter stored in the horizontal rail, and a lighting fixture is arranged between the louver and the surface of the shutter storage area. This is an overhead door with a louver.

[Effect]

According to the louvered overhead door of this invention, the louver is installed to cover the entire shutter storage area when the frontage opening is opened, making it difficult to see the storage status of the shutter and adding accents to the interior atmosphere. Improve.

Furthermore, since the lighting equipment is placed between the louver and the shutter storage area surface, the light from the lighting equipment that is the light source is backlit from overhead, making the shutter storage area located above the lighting equipment even more visible. At the same time, the installation position of the lighting equipment is lower than the ceiling, so high illuminance can be obtained.

〔Example〕

An embodiment of this invention will be described based on the drawings. FIG. 1 is a perspective view of the louvered overhead door as seen from the interior, FIG. 2 is a side view of FIG. 1, and FIG. 3 is a perspective view of the louver as seen from above.

Since the structure of the overhead door A is the same as that of the prior art, a description of the structure will be omitted, but the same numbers are given to the same members and parts.

The overhead door A has a louver F configured as follows. The louver F has vanes 12 arranged in a rectangular frame 11 in a vertical and horizontal lattice pattern, with the vanes 12 oriented vertically, and the space surrounded by the vanes 12 forms a rectangle. ing. This louver F is within the installation range of both horizontal rails 2.
Guide groove 2' into which shutter B was sent and stored,
Of the opposing areas 2', at least a shutter storage area G, which is the size of a shutter, is formed in a size that covers the entire surface of this storage area G. The installation mode is such that it is installed horizontally at a position lower than the horizontal rail 2, that is, below, and near the height of the frontage opening E. The specific means for attaching the louver F is to further extend downward the stays 7', which are provided at four locations from the ceiling to the reinforcing angle 6 of the horizontal rail 2, and to attach the stays 7' at four locations on the outside of the frame 11 of the louver F. It is fixed by welding, and the louver F is suspended together with the horizontal rail 2. As long as this stay 7' is outside the horizontal rail 2, in addition to the conventional stay 7 from the ceiling to the reinforcing angle 6, a stay from the reinforcing angle 6 to the frame 11 of the louver F may be fixed. .

Above the louver F, that is, the louver F
Lighting equipment H (fluorescent lamps in this embodiment) as light sources are arranged at four appropriate locations via mounting members I between the surface of the shutter storage area G and the shutter storage area G. The mounting member I includes a rod or plate-shaped mounting portion 13 having a length extending between the left and right reinforcing angles 6, and the mounting portion 1.
3, and these supporting members 14 are fixed to the reinforcing angles 6, respectively. Two lighting fixtures H are attached to the mounting portion 13 so that the light distribution is directed downward, that is, toward the louver F side. Although the power cord of the lighting fixture H is not shown, it is transmitted from the lighting fixture H to the support member 14 and the stay 7', and is wired from the ceiling to the connection part.

[Effects of the invention] Since this invention is constructed as described above, it has the following effects.

We installed a louver below the shutter storage area that spans the entire area, so the shutter storage area is hidden and the back side of the shutter is less visible, and the louver also acts as an accent, giving it a good look.

In addition, since the lighting equipment is placed between the louver and the shutter storage area, the light will be backlit from overhead, making it even more difficult to see the back side of the shutter located above the lighting equipment. Since the installation position is lower than the ceiling, high illuminance can be obtained, making the work area brighter and creating a better working environment.
