Description

[Detailed description of the invention] [Purpose of the invention] Industrial application field The present invention relates to a temporary pass-through door that is installed at the entrance and exit of a temporary enclosure at a construction site.

Conventional technology Conventionally, as a temporary pass-through door at a construction site, it is known that a pass-through door of about 2 m is installed in a frame with a total height of 3 m, but such a temporary pass-through door is formed in one piece. However, the overall problem was that it was bulky, making it difficult to carry.

Problems to be Solved by the Invention The present invention aims to provide a temporary pass-through door that is foldable, maintains its state when folded, and is compact and easy to carry and store.

[Structure of the idea]

Means for Solving the Problems In view of the above, the present invention connects the upper open lower frame and the lower open middle frame on the back side, and attaches a hanging body on the front side, and connects the lower frame. Inside the middle frame, a door consisting of a lower door frame and an upper door frame can be opened and closed, and the middle frame and upper frame are connected on the front side, and a hanging body is attached on the back side. The present invention attempts to solve the above-mentioned drawbacks by providing a temporary pass-through door with corresponding hanging bodies provided on the front side of the lower frame and the back side of the upper frame.

Function: When a temporary pass-through door is installed in a temporary enclosure at a construction site, it maintains harmony at the same height as the surrounding temporary enclosure, and the entrance/exit door is in a straight line for common use. When storing, it can be folded down to one-third of its total height and held in that state by engaging the hooks, making it compact.

Embodiment An embodiment of the present invention will be described below based on the drawings. 1 is a door body of a temporary crawling door;
The lower door body 2, the middle door body 3, and the upper door body 4 are divided into three parts.
The couplers 5, 5a provided on the sides of the door body 1 are installed at the same height as the temporary enclosures 6, 6a.

Upper open U-shaped lower frame 7 of the lower door body 2
The downwardly open U-shaped inner frame 8 of the inner door body 3 is
The lower door frame 11 and the upper door frame 12 are connected on the back side by hinges 9, 9a, and inside the lower frame 7 and middle frame 8, the door lower frame 11 and the upper door frame 12 are connected on the back side by hinges 10, 10a. They are connected by hinges 13, 13a... at
Males 15, 15a and females 16, 16a of a are attached respectively.

The upper part of the lower frame 7 of the middle door body 3 and the rectangular upper frame 17 of the upper door body 4 are connected to a hinge 18 on the front side,
18a..., and the male 20, 20a and female 21 of the hooking bodies 19, 19a are connected on the back side.
21a is installed.

Further, male parts 22 and 22a are attached to the lower surface side of the lower frame 7 of the lower door body 2, and a hooking body 23 is formed in correspondence with the female parts 21 and 21a. A female 24 is attached to the holder, and a hooking body 2 is attached to
5.

Note that 26, 27, and 28 are door plates for blindfolding, which are attached to the lower frame 7, middle frame 8, and upper frame 17, respectively, and 29 is composed of the lower frame 7 and middle frame 8 installed on the lower frame 7. This is a handle for opening and closing the door 30.

Next, to explain the function of the temporary pass-through door according to the present invention, the door body 1 is attached to the pipes of the temporary enclosures 6 and 6a.
Attach the couplers 5, 5a..., align the lower door body 2, middle door body 3, and upper door body 4, and install the door body 1 at the same height as the temporary enclosures 6, 6a. , male 20, 20a and female 21, 21
a, respectively, to form combined bodies 14, 14a, 19,
19a is hinge 10, 10a... and hinge 18, 18a
With the action of..., the lower door body 2, middle door body 3, and upper door body 4 are fixed in a straight line, and when going in and out from the door body 1, the door 30 consisting of the lower frame 7 and the middle frame 8 formed in a straight line is held by the handle. Operate 29 to remove hinges 13 and 1.
It is opened and closed by 3a...

Next, when storing the door body 1, fold it into three parts from the hinges 9, 9a, hinges 10, 10a, . . ., hinges 18, 18a, etc. as shown in FIGS.
1a and male 22, 22a, male 15, 15a and female 24
These hooks 23 and 25 hold the folded state and fix it compactly.

[Effect of idea]

In short, the present invention connects the upper-opening lower frame 7 and the lower-opening middle frame 8 with a hinge 9 on the back side.
9a, and the hanging body 1 on the front side.
Inside the lower frame 7 and middle frame 8, which are attached and connected with the hinges 10, 14a, there are a lower door frame 11 and an upper door frame 12, which are connected by hinges 10, 10a...
The door 30 consisting of the hinges 13, 13a... can be opened and closed freely, and the middle frame 8 and the upper frame 17
are connected by hinges 18, 18a... on the front side, and the hanging bodies 19, 19a are attached on the back side. Maintaining harmony, the door body 1 is connected to the hanging bodies 14, 14a, 19, 1 when entering and exiting.
9a are interlocked to form a straight plane, so it can be used in the same way as before, and when stored, it can be divided into three parts and folded compactly, making it easy to carry and saving space when stored. It can be devised.

Moreover, if the corresponding hanging bodies 23 and 25 are provided on the front side of the lower frame 7 and the back side of the upper frame 17,
Its practical effects are enormous, such as making it easier to carry.
