Description

[Detailed description of the invention] Industrial application field This invention relates to connecting sliding doors, and can be applied to gates, entrance doors, storm doors, partition doors, etc.

Conventional technology A horizontal slide groove is formed on one side of the door body, a slider is slidably fitted into this slide groove, and the slider is pivotally connected to one side end of the adjacent door body by a link. The connecting sliding door is Utility Model No. 52-83124,
It is described in Japanese Patent Application Laid-Open No. 61-40985, etc., and a door body is slidably suspended on the side of a support column, and a guide groove is formed on the outside of this door body, so that adjacent door bodies can be moved freely. A sliding door connected to a sliding door is disclosed in Japanese Utility Model Application No. 51-97339 and Japanese Utility Model Application Publication No. 61-146398.

Problems to be solved by the invention: A hanging side door is slidably suspended on the side of a support column, a horizontal guide groove is formed on the outside of the hanging side door, and a slider is slidably inserted into this guide groove. In the case of a connected sliding door in which one end of the door stop side door and the slider are pivotally connected by a link, the door stop side door is pushed back and forth and outward, and it is moved left and right to move along the passage. When opening, the hanging side door slides at the same time, making the movement of both door bodies inconsistent and difficult to operate smoothly.

Means for Solving the Problems In view of the above circumstances, the inventors of the present invention have conducted intensive studies, and as a result, the rotation angle of the link in this type of connected sliding door is regulated within a predetermined range, and one side of the door on the door stop side is By installing a tension spring between the end and the slider, the door body can be opened and closed smoothly.

In order to regulate the rotation angle of the link when implementing this proposal, a stopper is provided at one end of the door on the door stop side or on the slider, as shown in Figure 1 or Figure 6, so that the link is relative to the slider. A slider that comes into contact with the stopper when rotated to the orthogonal position, and has horizontal guide grooves formed at the top and bottom of the outside of the door on the hanging side door, and fits into the guide grooves at the top and bottom ends of the door stop side door. The upper slider and the lower slider should be pivotally connected by links, and a support rod should be interposed between the upper slider and the lower slider to integrally connect them. In this case, the tension spring should be attached to either the upper or lower door stop. By providing it between the side door and the slider, the intended purpose can be achieved.

Function According to this invention, the rotation angle of the link is regulated within a predetermined range, and a tension spring is stretched between one end of the door on the door stop side and the slider. In this case, as shown in Figure 1 or Figure 6, the link rotates to the maximum extent due to the force of the tension spring, and the door on the door stop side is placed at a predetermined distance in front and behind the door on the hanging side. Therefore, the door stop side door does not move irregularly when opening and closing, and the guide protrusion provided on the door stop side door fits properly into the groove of the guide frame provided on the hanging side door. be able to.

Furthermore, as shown in Figure 3, when the door body is extended to the maximum extent against the force of the tension spring, the tension spring tensioned between the door stop side door and the slider Since it is located almost parallel to the direction and the component force that rotates the link is extremely reduced, both doors can be kept stably in a straight line.

Embodiment The drawing shows the connecting sliding door of the present invention, in which receivers 3, 3, in which vertical guide rollers 2, 2 are provided spaced apart in the front and back direction, are provided facing each other on the upper and lower sides of the support 1, and A hanging side door 6 with vertical bars 5, 5... arranged between the frames 4, 4 is slidably suspended on the holders 3, 3, and upper and lower horizontal frames 4, 4 in the hanging side door 6 are attached. A slider 8 is slidably fitted into horizontal guide grooves 7, 7 formed on the outside of the door stop side door 9, and supports 10, 10 are fixed to the outside of the inner end of the upper and lower horizontal frames 4, 4 of the door stop side door 9. and the slider 8, links 11, 11 are installed between the link 11 and the slider 8.
The link and the support 10 are rotatably attached to each other, and the sliders 8, 8 at the upper and lower positions are connected to the support rods 12, 1.
2, which are integrally connected by..., supporting shafts 13, 13 are implanted at the bottom of the slider 8 and the support 10 at the lower position, and a tension spring 14 is stretched between the two supporting shafts,
As shown in FIG. 1 or FIG.
Or a stopper 15 inside the slider 8,
15 is provided to restrict the rotation angle of the link 11 to a position orthogonal to the slider, and the door stop side door 9
A guide protrusion 16 is integrally formed on the lower horizontal frame of the
A guide frame 17 having a groove into which the guide protrusion 16 is loosely fitted is fixed to the lower horizontal frame 4 of the hanging side door 6.

18 in the figure represents the door stop pillar.

Effects of the invention According to this invention, it is possible to smoothly open and close the door body.
