Description

[Detailed Description of the Invention] Industrial field of application The present invention relates to a connecting sliding door, and can be applied to gates, entrance doors, rain doors, partition doors, and the like.

2. Description of the Related Art A horizontal slide groove is formed in the upper and lower parts on one side of one adjacent door body, a slider is slidably fitted in the upper and lower slide grooves, and one end of a link is attached to the upper and lower sliders, respectively. The other door body is rotatably pivoted, and one end of the other adjacent door body is rotatably pivoted to the other end of the link, and when the door is extended, the respective door bodies are positioned in a straight line. The connecting sliding door is described in Japanese Utility Model Laid-Open No. 52-83124 and Japanese Patent Laid-Open No. 61-40985.

Problems to be Solved by the Invention In the conventional sliding door of this kind, since the connecting mechanism is provided independently in the upper part and the lower part of the adjacent door body, it is necessary to hold the door end part. When pulling out or pushing in, the connecting mechanism in the upper part of the door body, to which force is applied, operates earlier than the connecting mechanism in the lower part of the door body to which force is not applied, in addition to the action force to move the door body in the horizontal direction. A bending or twisting moment is generated in the door body, and the slider excessively abuts the slide groove, which makes it difficult to open and close the door smoothly.

Furthermore, since the upper and lower sliders and the adjacent other door body are connected only by one link, respectively, the action force that regulates the other door body in parallel with the slider is provided. It is scarce, and this is a factor that makes it difficult to open and close the door smoothly.

Means for Solving the Problems As a result of intensive studies made by the present inventors in view of such circumstances, as a result of connecting adjacent door bodies, a horizontal slide groove is formed in the upper and lower portions on one side of one door body. The slider is slidably fitted in the vertical slide groove, one end of each link is rotatably attached to the vertical slide, and one side end of the other adjacent door is attached. In a connecting sliding door pivotally attached to the other end of the link, a plurality of links having the same distance between supporting shafts are provided in parallel between the upper and lower sliders and the other adjacent door body. It is intended to achieve the intended purpose by arranging a connecting rod between the upper and lower links or the upper and lower sliders.

According to the present invention, since a plurality of links are arranged between the upper and lower sliders and the other adjacent door body, when the door body on the open end side is pushed out or pulled in, the door body is slid. Since it can always be placed in and out of parallel with respect to, and the connecting rod is installed between the upper and lower links or the upper and lower sliders, when pushing or pulling while holding the upper part of the door , The force applied to the link or slider in the upper part of the door is immediately transmitted to the link or slider in the lower part of the door via the connecting rod.
Due to the fact that the connecting mechanisms at the upper part and the lower part of the door body operate in synchronism with each other, the opening / closing operation can be remarkably smoothed.

Embodiments The connecting sliding doors shown in FIGS. 1 to 4 are made of hollow aluminum molded material and have vertical bars between the horizontal bars (2) and (2) at the upper and lower positions.
(3) It uses the door body (1) with (3) ...
(2) A strip notch (4) is formed on one side of (2), and a hollow slide groove (5) is formed inside which a roller fits, and the end of the cross rail (2) (2) ... Cut the part in a slanted shape, and slide the stopper for the slider to one side slightly inward from the pipe end of the horizontal rail (2) (2).
Attach (6), U-shaped body (8) and vertical roller (9)
Sliders (7) and (7) having (9) are provided by slidably fitting the vertical rollers (9) and (9) into the upper and lower slide grooves (5) and (5) of the door, respectively. The ends of the links (10) and (10) that connect the other door (1 ') adjacent to the U-shaped body (8) (8) and have the same distance between the support shafts are rotated in parallel. The links (10) (1) provided on the upper and lower parts of the door body for freely pivoting
Insert the knurled end of the connecting rod (11) (11) into the shaft hole with the knurl groove of (0), and integrate the link (10) (10) with the connecting rod (11) (11). Sticking to and connecting rod (11) (11)
The sliders (7) and (7) are provided with the protruding ends of which are pivotally mounted on the U-shaped main body (8) (8), and the other ends of the links (10) and (10) are adjacent to each other. Fitted into a receiver (12) having a U-shaped main body fixed to the slanted end of the door body (1 '), the links (10), (10)
The receiver (12) is rotatably fixed by the pin shafts (14) and (14) with the bush (13) interposed. Therefore, the door body
(1 ') can be kept parallel to the sliders (7) and (7) at all times.

In the figure, (15) is a link stopper provided on the slider (7),
Reference numeral (16) represents a link holding spring provided on the receiving member (12).

FIG. 5 shows another embodiment of the connecting sliding door of the present invention. In the connecting sliding door shown in FIGS. 1 to 4, the upper and lower sliders (7) and (7) are adjacent to each other. (1 ′)
And (10) (10) with the same distance between the support shafts are arranged in parallel with each other, and the connecting rod (1)
1) is fixedly provided.

Effect of the Invention According to the present invention, since the opening and closing operation of the door body can be remarkably smoothed, it can be applied to gates, entrance doors, rain doors, partition doors, and the like to exert remarkable effects.
