Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a garage opening/closing mechanism in which a door is flipped up, that is, pushed upward, and opened along a curved rail.

In the conventional manual garage opening/closing mechanism of this type, the tip of the door is raised upward by the force of a spring attached to the side wall of the garage body, and the tip is locked to the garage ceiling, etc., and the side edge of the door is held in a striated shape. Because the door is supported by a poking rod, it is difficult to hold it in the middle of opening and closing, and even if it is held in the middle and stored, the lower end of the door protrudes from the garage body like an eaves, and as a result, the poking rod itself In addition to being a hindrance to traffic, the length of the poking rod (between the fulcrum and the point of action) is long, which causes lateral sway, which can cause the door side edge to come into contact with the inside of the garage, causing paint to peel off and the opening and closing not being smooth. It had drawbacks such as:

The purpose of this invention is to eliminate the above-mentioned drawbacks, to make the door easy to hold in the middle of opening and closing, with less protruding parts, and to allow the door plate to be completely stored inside the garage body when opened. To provide an opening/closing mechanism for a garage that does not obstruct traffic in any way, is easy to open/close, and does not cause lateral shaking.

Hereinafter, the present invention will be described in detail based on embodiments shown in the drawings.

First, as shown in FIG. 1, the garage main body 4 to which the garage opening/closing mechanism of the present invention is attached has left and right side walls 1 and 2 and a ceiling 3, and usually also includes a rear wall (in some cases, it may be omitted). can.

) Furthermore, the garage main body 4 may be of a prefabricated type, and the foundation A that is installed on the foundation A of concrete or the like is preferably buried underground.

A door plate 5 is provided at the entrance opening of the garage main body 4 having the above-described structure to shield the entrance opening.

Upper rollers 6.6 for suspending and supporting the door plate 5 are provided on the left and right sides of the upper end of the door plate 5.

As shown in FIG. 2, a straight rail 7.7 for guiding the upper roller 6.6 is horizontally provided at the upper end of the inner surface of the left and right side walls 1, 2 of the garage body.

Note that the straight rail on the side wall 2 side is not shown.

Further, a lower roller 8 is rotatably provided at the left end of the lower portion of the door plate 5.

This may be provided at the right end of the door plate, or may be provided on both sides.

Next, a roller row 9 connected in a chain is coupled to the lower roller 8.

These lower rollers 8 and roller row 9 are guided by curved rails 10.

The curved rail 10 is provided on the inner surface of the side wall 1 of the garage main body, and its front end extends perpendicularly along the entrance end of the side wall 1, and its rear end extends along the upper end of the side wall 1 and the straight line. It extends horizontally along the bottom of the rail 7, and is smoothly curved in the middle.

Note that the curved rail 10 is attached to both the side walls 1.2 when the lower rollers 8 are provided at both left and right ends of the door plate.

The straight and curved rails 7.10 have a substantially C-shaped cross section as shown in FIG. 3, and a protrusion is formed at the center of the bottom to prevent the rollers 6.9.8 from escaping and the door from rolling. has been done.

Further, as shown in FIG. 2, one end of a tension spring 11 is attached to the upper end of the roller row 9.

The tension spring 11 is for assisting when the door plate 5 is opened upwardly, and does not have enough tensile force to pull the door plate 5 up with its own blade.

Note that the tension spring 11 is housed in a cylinder 12 as shown in FIG.

As shown in FIG. 6, the other end is connected to the rail 10.
It is attached to a suitable stopper 13 provided at the end of the holder.

Furthermore, the lower roller 8 is attached to the door plate 5 in a configuration as shown in FIG. 5, for example.

In the garage opening/closing mechanism configured as described above, when the door plate 5 is in the closed position, the upper roller 6 is located at the entrance side end of the garage within the straight rail 7, and the lower roller 8 is located within the curved rail 10. located at the lower end of

Next, when opening the door from this state, all you have to do is hold the handle provided at an appropriate position on the door plate 5 and push it upwards. As a result, as shown in FIG. Then, the lower roller 8 moves to the back of the garage, and the lower roller 8 also moves above the curved rail 10 as shown by the arrow.

At this time, the door plate 5 is pushed up while being inclined as shown in the figure, and when it is completely pushed up, it becomes almost horizontal as shown in FIG.

As shown in the figure, the door plate 5 does not protrude outside from the garage body when it is completely opened.
It does not become an obstacle to people's passage.

Furthermore, by balancing the weight of the door, the degree of curvature of the curved rail 10, and the tension spring, the door can be opened and closed easily and stably held at any desired position.

As explained above, according to the present invention, it is possible to obtain an opening/closing mechanism for a garage that does not obstruct traffic when the door is opened, as well as an opening/closing mechanism that can achieve the above-mentioned object of the present application. It is.
