Description

[Detailed description of the invention] The present invention relates to a door having a center-folded part used in a speaker box, etc.
The mounting piece 2 extends from both ends of the mounting piece 2.
A mounting body 4 is formed by providing a mounting hole 3 in the inner surface of both legs 9 of the U-shaped body 1, and a cam groove member 21 having a groove 10 formed therein. A pair of connecting pieces 5 with a pivot 6 installed between them 21 and whose center portions are pivotally connected with a pin 7 so as to be relatively rotatable.
A leg-like member 5a with a hole is formed at one end, and a connecting leg-like member 5b is formed at the other end, and the connecting piece 5 is rotatably attached to the pivot 6 in the hole 5c of the leg-like member 5a with a hole. The free end 8 of the connecting leg-like member 5b is slidably inserted into the cam groove 10 of the cam groove member 21 of the other mounting body 4, and the free end 8 and the connecting leg-like member 5
The distance l from the base end 5d of b is shorter than the shortest distance L between the cam groove 10 and the edge of the side opening 12 of the U-shaped body 1 on the opposite side from the pivot 6 at any position of the cam groove 10. The U-shaped body 1 of the upper mounting body 4 is inserted into the hole 16 formed in the lower end 15 of the upper door half 14 to form a hinge 13, and the lower end is pivoted so as to be vertically movable. The upper end surface 18 of the lower door half 17
This relates to a door having a center-folded portion, which is attached by inserting the lower mounting body 4 into a hole 16 formed in the door.

The purpose of this invention is that while the entire door can be opened wide, only the upper half of the door can be opened, the upper half has a storage compartment that is frequently opened and closed, and the lower half has a storage compartment that is frequently opened and closed. The object of the present invention is to provide a door having a folded part that is effective for things such as speaker boxes that house speakers and are opened and closed infrequently.

Embodiments of the present invention will be described in detail below with reference to the drawings.

Attachment pieces 2, 2 extend from both ends of the U-shaped body 1, and an attachment hole 3 is provided in the attachment piece 2 to form an attachment body 4. A connecting piece 5 is rotatably connected to a pivot 6 provided across the U-shaped body 1 on each of the pair of upper and lower mounting bodies 4, 4. A pair of upper and lower connecting pieces 5, 5 are crossed and pivotally connected to each other by a pin 7 at the crossing portion. The free end 8 of the connecting piece 5 is slidably inserted into a cam groove 10 provided in the leg 9 of the U-shaped body 1 of the other mounting body 4. The cam groove 10 is set between a pair of mounting bodies 4,
When the mounting pieces 2 and 2 of No. 4 are swung apart from each other from the state in which they face each other, U
Connection piece 5 housed in inner space 11 of character-shaped body 1
The free end 8 of the U-shaped body 1 is set so as not to protrude from the side opening 12 of the inner space 11 of the U-shaped body 1. The hinge 13 configured in this way is installed by inserting the U-shaped body 1 of the upper mounting body 4 into the hole 16 formed in the lower end surface 15 of the upper door half 14 formed in a louver shape, and attaching it with screws. A lower door half 17 is pivotally connected to the lower end so as to be vertically movable and is formed in a louver shape.
The lower mounting body 4 is inserted into the hole 16 formed in the upper end surface 18.
Insert it and attach it with screws.

In addition, along the legs 9 of the U-shaped body 1 and the mounting piece 2,
A thick plate 10a in which a cam groove 10 is formed is attached. Therefore, the hinge 12 has mounting pieces 2 extending from both ends of the U-shaped body 1 and mounting holes 3 in the mounting pieces 2.
A mounting body 4 is formed by providing a cam groove member 21 made of a thick plate 10a with a cam groove 10 formed on the inner surface of both legs 9 of the U-shaped body 1, and forming a mounting body 4. A pivot 6 is installed between the connecting pieces 6 and 21, and a leg-like member 5a with a hole is formed at one end of a pair of connecting pieces 5 whose center portions are pivotally connected with a pin 7 so as to be relatively rotatable, and connected to the other end. A leg-like member 5b is formed, the connecting piece 5 is rotatably attached to the pivot 6 in the hole 5c of the leg-like member 5a with a hole, and the free end 8 of the connecting leg-like member 5b is attached.
the cam groove 10 of the cam groove member 21 of the other mounting body 4
The distance l between the free end 8 and the base end 5d of the connecting leg-like member 5b is set so that the distance l between the free end 8 and the base end 5d of the connecting leg-like member 5b is set so that the distance l between the cam groove 10 and the pivot shaft 6 is It is configured to be shorter than the shortest distance L to the edge of the side opening 12 of the U-shaped body 1.

According to such a configuration, as shown in FIG. 3, the lower end surface 15 of the upper door half 14 and the upper end surface 18 of the lower door half 17 are brought into contact with each other, as shown in FIG. , only the upper door half 14 can be opened at the hinge 13. In such a case, the free end 8 of the connecting piece 5 that was housed in the inner space 11 of the U-shaped body 1 is inserted into the side opening 12 of the inner space 11 of the U-shaped body 1.
The free end 8 of the connecting piece 5 does not come into contact with the side of the hole 16. Therefore, a speaker (not shown) is stored below the speaker box 19, and a shelf 20 is provided above the storage section 21.
By doing so, it is possible to easily open only the upper door half 14 on the side of the storage section 21, which is frequently used for storing records, books, cleaners, etc., and by opening the lower door half 17, It can also be opened.

In summary, by using the above-mentioned hinge, the present invention allows the lower end surface of the upper door half to face the upper end surface of the lower door half, making it possible to create a door that looks like a single piece. Only the upper door half can be opened and closed.
In addition, the lower door half can be opened together with the upper door half, and the whole can be opened wide, such as a speaker box where the speaker is stored in the lower part and the upper part is used to store records, books, cleaners, etc. The distance between the free end of the connecting leg-like member and the proximal end of the connecting leg-like member can be adjusted to the side of the U-shaped body opposite to the cam groove and the pivot at any position in the cam groove. Since the distance is shorter than the shortest distance to the edge of the opening, when the mounting pieces of the pair of mounting bodies are swung apart from each other from the state in which they are facing each other, the distance between the mounting pieces can be accommodated in the inner space of the U-shaped body when the mounting pieces are in the face-to-face state. The connecting piece that was attached to the U-shaped body does not protrude from the side opening of the inner space of the U-shaped body, and the door can be folded in the middle to open and close smoothly. It is installed by inserting the U-shaped body, and the lower mounting body is inserted into the hole formed in the upper end surface of the lower door half, whose lower end is pivoted so that it can move up and down.
This has the advantage that the hinge can be hidden when the door is closed, improving the appearance.
