Description

[Detailed description of the invention] This invention relates to an improvement of a push-up sliding door for opening and closing openings such as windows and entrances in buildings.It has a simple structure that allows multiple door panels to be compactly arranged in an upper door pocket. The present invention provides a push-up sliding door that can be stored in the room.

To explain the embodiment of the present invention using drawings, 1 shows a part of a building, 2 is an opening such as a window or a doorway provided in the building 1, and 2 are attached to pillars or walls at both ends of the building 1. The inner and outer guide rails 3, 3', 3, 3' of the strips are integrally arranged closely and in parallel in the vertical direction, and the guide rails 3, 3' are attached to the outer wall of the building 1 above the opening 2. At both ends of the fixed door pocket 10, the inner guide rails 3, 3 are extended upward to form a vertical extension rail section 3b, and then bent diagonally outward and upward at the upper part of the door pocket 10 to form an inclined rail section. 3a, outer guide rail 3'
, 3' are bent diagonally outward and upward at the lower part of the door pocket 10 to form inclined rail parts 3a', 3a' parallel to the inclined rail part 3a.

4, 4... 4 is a plurality of door panels that close the opening 2 by bringing their upper and lower end surfaces into close contact with each other, and on both end surfaces of each door panel 4, guide wheels 5 are provided on the inner side of the upper end and the outer side of the lower end. 5, 5
', 5' are rotatably pivoted, and the upper guide wheels 5,
5 to the inner guide rails 3, 3, lower guide wheels 5', 5
' are slidably engaged with the outer guide rails 3', 3', respectively.

In addition, the dimension between the upper and lower guide wheels 5 and 5' is determined based on the inclined rail portion 3.
It is made equal to the dimension between a and 3a.

The weight of each of these door panels 4 is balanced by a pair of left and right suspension devices 6 disposed in the upper part of the door pocket 10, and each suspension device 6 is connected to a hanging band 7 connected to the upper part of each door panel 4 and the suspension device 6. Balancer 8 forcibly winding band 7
The balancers 8 are slidably mounted on groove members 13 that are inclined downwardly toward the outside at the upper end of the door pocket 10.

Reference numeral 9 denotes a bracket for the door pocket 10 to which the inclined rail portions 3a of the guide rails 3, 3' are fixed.

Reference numeral 11 denotes a hook body whose base end is rotatably pivoted to the pivot of the guide wheel 5 on the upper part of the door plate 4, and is always tilted outward due to the elastic force of the hook body itself or an appropriate elasticity. When the door plate 4 moves downward, it is engaged with a pin 12 provided at the lower end of the adjacent door plate 4.

To explain the operation of the embodiment configured as described above, as shown in FIGS. 1 and 2, door panels 4...4
When an arbitrary door plate 4 is pushed up while the opening is closed, the door plate 4 moves to the guide rails 3, 3' via the guide wheels 5, 5.
The upper guide wheel 5 moves upward along the inner guide rail 3.
After reaching the upper end of the vertically extending rail 3b, the vertical guide wheels 5, 5' move along the vertically inclined rail portions 3a, 3a'.

In this way, the doors from the top door plate 4 to the bottom door plate 4 are sequentially stored in the door bag 10.

If the lifter 8 of the suspension device 6 is adjusted to have a strength equal to the weight of the door plate 4 during this operation, the door plate 4 can be pushed up with a small amount of force via the hanging band 7.

That is, by pushing up the door plate 4, each door plate 4 can be stored in the door pocket 10 as shown in FIGS. When the entrances of the rail portions 3 a and 3 a' are moved slightly outward, the lower door plate 4 adjacent to the door plate 4 then rises along the vertical extension rail portion 3 b, so that the hook body 11 It is automatically detached from the pin 12.

Next, when shielding the opening 2, the last stored door plate 4 is pulled down from the door pocket 10, and the hanging band 7 is pulled out from the balancer 8 and stops in an extended state. , a hook body 11 pivotally fixed to the upper end of the door plate 4
The next door plate 4 is engaged with the pin 12 provided at the lower end of the door plate 4, and the door plate 7 stored in the door bag 10 is moved in the same way.
4 in sequence to close the opening 2 (this state is shown in FIGS. 11 to 13).

In the above embodiment, the door plate 4 is provided with the suspension device 6, the hook body 11, and the pin 12, but such a mechanism is not necessarily required when moving the door plate 4 up and down one by one.

As described above, in the present invention, two inner and outer guide rails 3, 3', 3, 3' are vertically arranged in parallel on both sides of the opening 2 of the building 1, and the guide rails 3, 3' In the door pocket 10 provided above the opening 2, the rails 3a and 3a' are bent diagonally upward in parallel with an appropriate interval vertically, or the inside and outside of these rails 3a and 3a' are bent in parallel. A plurality of door plates 4, 4...4 arranged in a vertical line along the guide rails 3, 3' are moved up and down, and guide wheels 5 are provided at the upper and lower portions of both end surfaces of each door plate 4. ,5'
This relates to a push-up sliding door in which the upper guide wheel 5 is slidably engaged with the inner guide rail 3 and the lower guide wheel 5' is slidably engaged with the outer guide rail 3'. However, it is not possible to completely close the opening 2 of the building 1 by bringing the upper and lower end surfaces of the plurality of door panels 4, 4, . When opening, each door plate 4 is moved upward sequentially starting from the upper door plate 4, so that the upper and lower guide wheels 5, 5' are respectively guided by the inclined rail portions having an appropriate interval vertically, so that the door plates 4 are overlapped in the front and rear direction. The guide wheels 5 and 5' provided at the upper and lower ends of each door plate 4 are individually engaged with the guide rails 3 and 3', respectively. Therefore, when the door plate 4 is moved up and down, it is guided by the inclined rail part 3a of one guide rail 3 and the inclined guide rail part 3a' of the other guide rail 3', so that the opening 2 can be reliably and smoothly closed. , the door plate 4 can be stored in the door bag 10, and the door plate 4 can be stored in the door bag 10.
When the innermost door plate 4 is pulled down from the stowed state, the other door plates 4 are sequentially and easily moved to the upper end side of the guide rails 3, 3' by the inclined guide rails 3a, 3a', making the closing operation easier. It is what it is.
