Description

[Detailed explanation of the invention] [Industrial application field] This invention is installed at the entrance of a hall or entrance, and is normally opened and closed by sliding, but in case of an emergency, the door can be opened by sliding. This door has a dual opening/closing function that rotates around a hanging shaft to open either outdoors or indoors, and relates to a support device for the part suspended by the hanging shaft.

[Conventional technology]

This type of door has a hanging frame slidably suspended from the upper guide rail, and the door is suspended from the hanging frame using a hanging shaft and a removable locking device. Although this is done by sliding, when opening and closing the door by rotating, the locking device is removed and the door is opened by rotating around the hanging shaft. The hanging shaft is installed on one side of the vertical stile or near it, and a locking device is installed on the other side. When the door is unlatched, the door becomes cantilevered by the hanging shaft, and the door does not tilt under its own weight. There was a problem. Various measures have been taken to solve this problem, and one example is the
-8472 publication is known. The idea in this publication is to insert a hanging shaft suspended from a hanging frame into the vertical stile of the door, insert a horizontal arm protruding from the hanging shaft into the upper stile of the door, and link the upper stile and the horizontal arm with adjustment bolts. It is. According to this method, the horizontal arm and the lower end of the hanging shaft prevent the door from tilting.
Bending stress is applied to the horizontal arm protrusion of the hanging shaft, and pressing force is also applied to the part of the stile facing the lower end of the hanging shaft, which has the disadvantage of requiring reinforcement and making the door heavier.

[Problem that the invention attempts to solve]

This invention provides a door support device that allows only a vertical load to be applied to the hanging shaft without applying complicated stresses such as bending, thereby making the door lighter and more durable. There is a particular thing.

[Means for solving problems]

The door support device according to this invention is suspended from a hanging frame that slides along the upper guide rail.
In a support device for a door that slides and closes together with a hanging frame and rotates to open and close around a hanging shaft rotatably hanging from the hanging frame, a hanging lever is inserted into the upper stile of the door along the longitudinal direction. At the same time, one end of the hanging lever is pivotally supported on the stile by a horizontal support shaft, and an adjustment bolt inserted from the top surface of the door is screwed to the other end, and a hanging shaft is rotatably suspended from the hanging frame. The lower end of the suspension lever is integrally fixed to a portion closer to the horizontal support shaft between the horizontal support shaft and the adjustment bolt of the suspension lever.

[Effect]

A hanging lever suspended from a hanging shaft receives the load of the door on both ends to maintain balance, and opens and closes the door by receiving a load perpendicular to the hanging shaft.

〔Example〕

As shown in FIG. 1, the door 1 is formed of upper and lower frames 2 and 3 and left and right vertical frames 4 and 5, and each of the frames 2 to 5 is formed of a hollow profile. Guide rails 6 and 7 are provided above and below the door 1, and a hanging frame 8 is slidably suspended from the upper guide rail 6 by rollers 9 and 10 that sandwich it from above and below. Hanging shaft 11
A sliding part 13 that engages with the lower guide rail 7 is provided at the lower part corresponding to the hanging shaft 11 of the door 1, and corresponds to the locking part 12 of the door 1. The guide rod 14 is attached to the lower part of the lower guide rail 7.
When the door 1 is rotated and released, the locking portion is disengaged and the guide rod 14 escapes from the lower guide rail 7.

Therefore, as shown in FIG. 2, the hanging shaft 11 has a collar 15 at its upper end, a screw 16 cut into its lower part, and is rotatably suspended from a bearing block 17 fixed to the hanging frame 8. The lower part of this hanging shaft 11 is screwed into the middle part of the hanging lever 18 and fixed integrally with each other. The hanging lever 18 is the upper stile 2 of the door 1.
a horizontal portion 19 that is inserted into the interior for a long time in the longitudinal direction;
The vertical part 20 is bent and inserted into the vertical part 4 from the horizontal part 19, and its cross section is formed into a groove with an open bottom surface as shown in FIG.
Further, in order to fix the hanging shaft 11 to the hanging lever 18, a connecting block 21 having a female screw hole is fixed to a portion corresponding to the hanging shaft 11.

The hanging lever 18, which is inserted into the above-mentioned frames 2 and 4 and has the hanging shaft 11 fixed thereto, has its bent side end in the horizontal part 19 supported by a supporting shaft 22 installed horizontally inside the vertical frame 4, and An adjustment bolt 23 screwed into the upper wall of the upper stile 2 is pressed into contact with the upper surface of the other end of the portion 19. Further, a reinforcing frame 27 is provided at a position where the support shaft 22 is installed inside the vertical stile 4.

Furthermore, in the example shown in FIG.
9, and a flange-like stopper 25 that presses against the back surface of the upper wall surface of the upper stile 2 is screwed onto the adjustment bolt 23. Further, as shown in FIGS. 2 and 3, several steady-stop pieces 26 having a T-shaped cross section and whose heads protrude into the hanging lever 18 are fixed inside the upper stile 2.

When suspending the door 1, the upper stile 2 and the vertical stile 4 are assembled, and at the same time the suspension lever 18 is inserted inside them, and the lever 18 is supported by a horizontal support shaft 22 before being inserted. By screwing and fixing the hanging shaft 11 to the hanging lever 18 and further rotating the adjustment bolt 23, the door 1 can be hung normally. The load of the door 1 is applied in a balanced manner to the left and right sides of the fulcrum. Incidentally, the position of the horizontal support shaft 22 may be a vertical portion of the support shaft below the position shown in FIG.

[Effect of idea]

The door support device according to this invention has one end of a suspension lever inserted into the upper stile of the door supported by a horizontal support shaft, and an adjustment bolt inserted from the top of the door screwed into the other end. A hanging shaft rotatably suspended from a hanging frame is integrally fixed to the intermediate part between the two ends of the hanging lever, and the load of the door is transferred to the left and right from the fixed part of the hanging lever to the hanging shaft. Since the load is applied in a balanced manner, the load of the door is applied to the hanging shaft as a vertical stress, and even if the hanging shaft rotates, no unreasonable force is applied to the hanging shaft, and the door maintains its normal condition. Retained for a long time. Further, since no excessive force is applied, no special reinforcing means is required, and the parts of the door and its supporting means can be made lighter.
