Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to an improvement in the structure of a garage door attached to an entrance/exit of a garage.

[Background Art] Conventionally, in the case of a garage door, as shown in FIGS. 7 and 8, the base of an arm 2 is rotatably attached to the upper part of a column 1, and the tip of the arm 2 is attached to a door body 3.
It was configured so that it could be closed when the door body 3 was oriented vertically, and opened when the door body 3 was oriented horizontally above. However, in such a conventional example, the door body 3 is simply formed by attaching the door panel b over the entire surface of the door frame a, so when a person other than a car tries to enter or exit, the entire door body 3 must be closed. The large door body 3 must be opened and closed each time a person enters or exits, making it difficult for people to enter or exit. In order to eliminate this drawback, the applicant of the present invention previously filed Japanese Patent Application No. 60-188048 by providing an opening frame 8' on the door body 3, which has an upper frame 8a and side frames 8b on both sides as shown in FIG. An application was filed for a device in which the opening frame 8' is provided with a door 4 that can be opened and closed freely, but in this case, the strength is weak because the side frames 8b on both sides of the opening frame 8' are only connected by the upper frame 8a. There was a problem.

[Purpose of the invention] This invention was made in view of the above points, and the purpose of this invention is to open and close a small opening/closing door so that people can easily enter and exit even when the door body is closed. Moreover, it is an object of the present invention to provide a garage door whose strength does not weaken even when an opening/closing door is provided.

[Disclosure of the invention] The garage door of the invention has the base of the arm 2 rotatably attached to the upper part of the support column 1, the tip of the arm 2 is connected to the door body 3, and the door body 3 is closed with the door body 3 facing in the vertical direction. In a garage door that is opened with the door body 3 facing upward in a horizontal direction, the garage door has an upper frame 8a that projects upward from the upper end of the door body 3, side frames 8b on both sides, and a lower frame 8c. The opening frame 8 is provided on the door body 3, and the opening/closing door 4 is provided on the opening frame 8 so as to be freely openable and closable, and the drawbacks of the conventional example are solved by constructing it as described above. In other words, by providing the opening/closing door 4 in the opening frame 8 of the door body 3 so that it can be opened and closed, even when the door body 3 is closed, people can open and close the opening/closing door 4 to allow people to enter and exit.Moreover, the upper frame 8a of the opening frame 8 The opening frame 8 is made to protrude upward from the top surface of the door body 3.
By making the height higher than the top surface of the door body 3, even tall people can easily enter and exit, and by providing the lower frame 8c on the opening frame 8, even if the opening frame 8 is provided on the door body 3. It has become possible to maintain sufficient strength.

The present invention will be explained in detail below with reference to Examples.

Reference numeral 1 is a support post, which is installed on the left and right sides of the garage entrance. Reference numeral 2 denotes an arm, which is composed of an upper arm 2a and a lower arm 2b. The base ends of the upper arm 2a and the lower arm 2b are rotatably attached to the upper part of the column 1 together, and the tip of the upper arm 2a is connected to the upper part of the door frame 5 of the door body 3. The tip of 2b is connected to the middle part of the door frame 5 in the vertical direction. An opening frame 8 is provided on one side of the door frame 5 of the door body 3.
A door panel 6 is attached to the other parts. Instead of the door panel 6, a large number of vertical lattices may be provided. The opening frame 8 is composed of an upper frame 8a, side frames 8b on both sides, and a lower frame 8c, and the upper frame 8a has an arch shape so as to protrude upward from the upper end of the door frame 5. The upper frame 8a may protrude in a U-shape as shown in FIG. 4a, or may protrude in a triangular shape as shown in FIG. 4b. Further, in this embodiment, the lower frame 8c is integrally formed with the lower frame of the door frame 5 being longer than the upper frame of the door frame 5. This opening frame 8 is provided with an opening/closing door 4, which is rotatably connected to one side frame 8b of the opening frame 8 by a hinge 9. An opening/closing door 4 is attached to a side frame 8b different from the side frame 8b to which the hinge 9 of this opening frame 8 is attached.
A fixture 7 that can hold the opening/closing door 4 closed by fixing it.
is provided. The garage door is constructed as described above, and usually the door body 3 is oriented vertically to close the entrance and exit of the garage, and the opening/closing door 4 is also closed. When a person enters or exits in this state, the fixture 7 is released and the door 4 is opened or closed to allow the person to enter or exit. When a car enters or exits, the door body 3 is opened by rotating around the pillar 1 so that the door body 3 faces upward and horizontally. Support legs 13 are made to protrude from the lower end of the door body 3 as required. When the door body 3 is vertically closed, the support legs 13 are grounded and the door body 3 is held.

FIG. 5 also shows another embodiment of the description. In this embodiment, the door body 3 is constructed by attaching a plurality of vertical lattices 10 to the door frame 5. An upper rail 11 is provided on the upper frame of the door frame 5, and the lower frame of the door frame 5 and the opening frame 8
A lower rail 12 is provided on the lower frame 8c, and an opening/closing door 4 having a sliding door structure is slidably mounted between the upper rail 11 and the lower rail 12. With this arrangement, the door 4 can be opened and closed by sliding left and right like a sliding door, and does not take up much space.

Furthermore, FIG. 6 shows another embodiment of the description. In the case of this embodiment as well, the door body 3 is constructed by attaching a plurality of vertical lattices 10 to the door frame 5. The opening/closing door 4 is formed by attaching a vertical lattice 4b to a door frame 4a.

[Effects of the invention] As described above, the present invention has a door that can be opened and closed in the opening frame provided on the door body, so even when the door body is closed, the door can be opened and closed to allow people to pass through the opening frame. It is easy to open and close when people go in and out, and since the upper frame of the opening frame is designed to protrude above the top surface of the door body, the height of the opening frame is increased. Even tall people can easily enter and exit the door without having to bend down, and since the opening frame has a lower frame, even if the opening frame is installed on the door body, the lower frame can maintain sufficient strength. There is no problem in terms of strength.
