Description

[Detailed explanation of the idea] The present invention relates to a folding door.

This type of folding door, which is formed by connecting a pair of door panels so that they can be folded, does not have a locking mechanism to keep the folding door closed, so it may bounce when the folding door is strongly closed. There have been problems with the folding door opening, and the fact that the folding door cannot be locked when used as a toilet or bathroom door.

The present invention has been developed in view of the above points, and it is possible to securely hold the locking device in the closed state, and furthermore, the operating tool for operating the locking device is connected to the bearing projecting piece and the fitting curved piece. It is an object of the present invention to provide a folding door that can be provided using a spacer that maintains the fitted state with the folding door, and can have a simple structure.

Therefore, in the present invention, a bearing protrusion 2 is attached to the end of the receiving tool 1, which is formed to be vertically elongated and has a generally U-shaped cross section.
2 is provided in a protruding manner, and a fitting piece 5 is provided on the connecting tool 4 attached to the side end of the door panel 3, so that the fitting pieces 5, 5 can be horizontally rotated on both the bearing protrusions 2, 2, respectively. In a folding door in which a pair of door panels 3, 3 are foldably connected by the receiver 1 by fitting the door panels 3 and 3 outwardly, the locking tool 6 can be freely projected in the vertical direction from at least one of the upper end and the lower end of the receiver 1. Spacers 9, 9 for maintaining the fitting between the bearing projecting piece 2 and the fitting curved piece 5 are installed in the upper and lower parts of the receiving tool 1, respectively, and are used for vertical movement of the locking tool 6. Operation mounting spacer 1 with tool 7
The above object has been achieved by a folding door which is formed by attaching a folding door 0 within the receiver 1 between the upper and lower spacers 9, and the present invention will be described in detail below with reference to examples.

The receiver 1 is formed into a vertically elongated piece having approximately the same length as the upper and lower dimensions of the door panel 3, and its cross-sectional shape is approximately U-shaped. is installed protrudingly. The connector 4 is also formed in an elongated vertically with approximately the same length as the vertical dimension of the door panel 3, and has a fitting curved piece 5 with a substantially C-shaped cross section, and a serrated protrusion 8 is attached to the door panel 3. This connector 4 is attached to one side edge of the door panel 3 by driving into the end face. By rotatably fitting the fitting curved piece 5 of the connector 4 into the outer periphery of the bearing projecting pieces 2, 2 of the receiver 1, the connector 1 and the connector 4 can be connected to each other.
As shown in FIG. 2, the pair of door panels 3, 3 are foldably connected by means of a hinge comprised of the following. Here, if the one shown in FIG. 2 is used, the fitting curved piece 5 will be disengaged from the bearing protrusion 2, so the spacer is fitted into the receiving tool 1.
At the upper and lower parts of the receiver 1, spacers 9 as shown in FIG. 6c are used. This spacer 9 is formed by connecting one ends of the holding pieces 45, 45 having a substantially V-shaped cross section.
By pressing the fitting pieces 5, 5 against the bearing protrusions 2, 2, the fitting pieces 5 are prevented from coming off from the bearing protrusions 2, and the holding pieces 45,
Since the other end of 45 is free, the holding pieces 45, 4
5 is given elasticity so that the fitting piece 5 can smoothly rotate around the outer periphery of the bearing projection piece 2. Of the upper and lower spacers 9, the lower spacer 9 is prevented from coming off by an end plate 47 attached to the lower end of the receiver 1 with screws 46, and the upper spacer 9 is prevented from coming off by a box 22, which will be described later. At the upper and lower center of the receiver 1 between the upper and lower spacers 9, an operating tool mounting spacer 10 as shown in FIG. 6a is used. This operating tool mounting spacer 10 is also formed with holding pieces 48, 48 having a substantially V-shaped cross section similar to the spacer 9, and has the same function as the spacer 9. Further, in this upper and lower center portion of the receiver 1, a handle mount 11 is attached to the outer side of the receiver 1 so as to correspond to the operating tool mounting spacer 10. The operating tool mounting spacer 10 and the handle mounting tool 11 are shown in Figure 4a.
As shown in the figure, it is fixed to the receiver 1 with screws 12. As shown in FIG. 7, a slide tool 14 is disposed in a vertical elongated slide hole 13 provided in the receiver 1 between the upper part of the operating tool mounting spacer 10 and the handle mount 11. A spacer 10 for attaching an operating tool corresponding to the slide hole 13 and a bush 16 passed through elongated holes 15 at the top and bottom of the handle mount 11 are attached to the slide tool 14 to penetrate therethrough. Furthermore, there are 1 knobs on both ends of this bush 16.
7 and 17 are attached by screws 18 and 18, and by operating the knobs 17 and 17, the bush 16 is inserted into the long hole 1.
Slide tool 1 moves up and down along lines 5 and 15.

Further, the lower end of the upper operating rod 19 is fixed to the slide tool 14 with a screw 20, and a latch 6a as a locking tool 6 is attached to the upper end of the upper operating rod 19 with a screw 21.
It is fixed as shown in FIG. latch 6a
is vertically movable in a box 22 installed as a spacer in the upper end of the receiver 1.
3, it is biased upward. Therefore, the latch 6a protrudes upward from the inside of the box 22 by the elastic force of the spring 23, and is moved downward by the downward movement of the knob 17 (solid line state in FIG. 5a). Then, the upper operating rod 19 is moved downward, and the latch 6a is moved downward, so that the latch 6a can be retracted into the box 22. Note that 24 in FIG. 7 is a long hole provided in the upper operating rod 19. In addition, one end of the operating tool mounting spacer 16, the elongated holes 25, 25 provided at the bottom of the handle mount 11, and the slide elongated hole 26 provided in the receiver 1 in correspondence with the elongated hole 25. A bush 28 provided with a collar plate 27 is inserted therethrough, and a knob 29 is attached to the other end of the bush 28 with screws 30. The bush 28 and the knob 29 constitute the operating tool 7. The upper end of a lower operating rod 31 is fixed to this bush 28, and a drop 6b as a locking tool 6 is attached to the lower end of the lower operating rod 31 with screws 32. The drop 6b is housed between the receiver 1 and the spacer 9, and moves downward under its own weight so that its lower end protrudes downward from between the receiver 1 and the spacer 9. The drop 6b is inserted between the receiving tool 1 and the spacer 9 by pulling up the upper operating rod 31 via the bush 28 by an upward movement operation (imaginary line in FIG. 5a). Here, a U-shaped spring 36 is attached to the bush 28 with a screw 37.
When the bush 28 is moved upward, the U-shaped spring 36 is elastically engaged with the screw 12 as shown in FIG. I have made it possible.
