Description

[Detailed description of the invention] The present invention relates to a telescopic door suitable for gates, partitions, etc., and its purpose is to provide a telescopic door that is highly self-supporting and stable and has good operability.

To explain the present telescopic door in detail with reference to drawings, a door body frame 2 is formed by integrally connecting large and small inverted U-shaped frames 1 and 1' at their parallel parts, and the other inverted U-shaped frame 1, 1' and inverted U-shaped frames 3, 3' of different heights are integrally joined at their parallel parts to form a door frame 4, and both door frames 2, 4 are combined into an X-shape. Multiple inverted U-shaped frames 1 and 3 and small inverted U-shaped frames 1' and 3' of the intersecting door body frames are rotatable, respectively. Link rods 5, 5 are rotatably provided in the lower ends of the small inverted U-shaped frames 1', 3' of both intersecting door frames, and intersecting in an X-shape. It has been discovered that a highly functional extendable door can be mass-produced at low cost by hingedly connecting the body frames 2 and 4 so as to be relatively rotatable.

In implementing this proposal, for example, large and small inverted U
The parallel parts of the character frame are connected to spectacle-shaped bearings 6, 6...
A bearing protrusion is formed on the outer end of the spectacle-shaped bearing, the adjacent spectacle-shaped bearings are overlapped, and a pin shaft is inserted into the shaft hole of both bearing protrusions to connect them. The auxiliary door frame at the end should be approximately half the width of the main door frame, and in order to pivotally support the inverted U-shaped frame, a bearing 7 is caulked to each inverted U-shaped frame, and a When inserting and screwing the pin shaft 8 and pivoting the large and small inverted U-shaped frames and the intersecting positions of the link rods 5, 5, insert the vertical shaft 9 at each intersection to provide pivot support. Good.

In the figure, reference numeral 10 denotes a wheel, and its bearing portion can be fixedly provided in the shaft hole of the bearing protrusion of the spectacle-shaped bearings 6, 6 at an appropriate position.

The present proposal has the above-mentioned configuration, and the door frame 2, 2...
The door body can be expanded and contracted by mutually rotating the door body frames 4, 4, etc., and the door body is formed by crossing the door body frames, which are made up of large and small inverted U-shaped frames, in an X-shape. As a result, the weight of the door body is evenly distributed in the front-rear and left-right directions, allowing the door body to stand on its own with good stability in any state, and the size of the door body frame 2 crossed in an X shape. Inverted U-shaped frame 1,
1' and the large and small inverted U-shaped frames 3 in the door frame 4,
When the door bodies are folded at different heights, one door frame and the other door frame can be overlapped and folded, allowing the large and small inverted U-shaped frames to be integrated at their parallel parts. The door frames connected to each other are crossed in an X-shape, and the large inverted U-shaped frames 1 and 3 and the small inverted U-shaped frames 1' and 3' of each door frame are rotatably attached to each other, The link rods 5, 5 crossed in an X-shape are rotatably connected to the lower ends of the small inverted U-shaped frames 1', 3' of the intersecting door frames, and the adjacent door frames are connected to each other. Since the door frame is hinged, the door frame is extremely firmly connected in the vertical and horizontal directions, and the force applied to one end of the door is synchronously propagated to the entire door, making it open and close extremely smoothly. It has many benefits when used, such as cleaning.

[Brief explanation of drawings]

Figure 1 is a front view showing an example of the telescoping door of the present invention;
The figure is also a plan view, Figures 3 and 4 are front views showing the door body frame of the original telescoping door, and Figure 5 is an enlarged vertical sectional view showing the pin joint in the inverted U-shaped frame of the original telescoping door. , Fig. 6 is an enlarged sectional view showing the link rod attachment part of the telescoping door of the present invention, with parts 1, 1', and 1' in the figure.
3 and 3' are inverted U-shaped frames, 2 and 4 are door frames,
5 represents a link rod.
