Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a matching bar for a horizontal sliding door equipped with a sensor for preventing jamming.

[Prior art] Conventionally, in horizontal sliding doors that open and close in the horizontal direction, a closing bar is fixed by welding or the like at the joint between the door end side and the door end side of adjacent face plates, and the gap between the face plates when closed is reduced. In addition to the above-mentioned structure, there is a system that detects if a person or an obstacle gets caught between the face plates that open and close, especially in the case of electrically operated heavy horizontal sliding doors. In many cases, a jamming prevention sensor that stops or rolls the door is attached to the side edge of the face plate to which the alignment bar is fixed to improve safety.

However, with horizontal sliding doors equipped with the above-mentioned jamming prevention sensor, the alignment bar protrudes from the face plate that opens and closes, so there is an inconvenience that the jamming prevention sensor does not activate even if the door jams an obstacle. If a jamming prevention sensor is installed, conventionally it is not possible to attach a closing bar, and drafts may blow in from the joints of closed doors, or people may be able to see inside. This was inconvenient.

[Problems to be solved by the invention] The present invention was devised in view of the above-mentioned actual situation, and its purpose is to stop or prevent the door from rolling by detecting an obstacle using a jamming prevention sensor. Although it is possible to
The gap between the closed faceplates can be reliably covered by the closing bar, and the horizontal sliding door is equipped with a jamming prevention sensor that improves both the safety and closing performance of the horizontal sliding door. It is intended to provide a matching bar.

[Means for Solving the Problem] In order to solve the problem, the technical means adopted by the present invention is to arrange a plurality of face plates horizontally and suspend them movably, and to hold obstacles between the face plates. In a horizontal sliding door equipped with a sensor to prevent jamming, a matching bar that can move forward and backward between the adjacent door end side and door end side of the face plate is installed, and a matching bar is installed on the side where the matching bar is installed. A detection element of a sensor for preventing pinching is provided on the side end face of the face plate so as to be able to protrude and retract freely, and the above-mentioned matching bar is configured to be retracted in conjunction with the pinching of an obstacle between the face plates. It is.

[Operation of the invention] Therefore, according to the invention, the seam between the doors can be reliably shielded when the doors are closed, without interfering with obstacle detection by the jamming sensor.

[Example] The configuration of the present invention will be described in detail with reference to an example shown in the drawings.

1 and 2, reference numerals 1 and 1' denote horizontal sliding doors, and the horizontal sliding doors 1 and 1' have a hanging metal fitting attached to a hanging wheel 4 that is engaged with an upper rail 3 of an opening 2.
It is suspended via a door and is configured to be movable in the lateral direction by a door drive device (not shown).

A pinch prevention sensor 6 consisting of a stop or rolling switch is embedded in the end face of the door tip 1a of the horizontal sliding door 1 with its detector 6a protruding, and is also embedded in the end face of the horizontal sliding door 1'. A fitting hole 6b into which the detector 6a is fitted is provided. In addition, on the surface near the door tip 1a, there is a door tip 1a.
Elongated holes 7a, 7a extend from the a side toward the retraction side 1b.
A combination bar 7 formed by boring upwardly sloping...
is freely movably attached to headed pins 8, 8, which are planted apart in the vertical direction on the horizontal sliding door 1 side, and the elongated hole 7 is normally closed by the weight of the alignment bar 7.
Headed pins 8, 8... at the inclined upper position on a, 7a...
... and maintains a state in which it protrudes from the end surface of the door tip side 1a toward the horizontal sliding door 1'.

In the configuration as described above, the horizontal sliding doors 1, 1'
When they come together, the detection element 6a of the jamming prevention sensor 6 provided on the side of the horizontal sliding door 1 fits into the insertion hole 6b provided on the end face of the door 1', and the closing state is established. straddles between each door 1, 1' and closes the seam, so that the seam of the closed doors can be shielded.

During the closing operation of such horizontal sliding doors 1, 1',
If an obstacle 9 exists in the opening/closing area, as shown in FIGS. 3 and 4, when the matching bar 7 first comes into contact with the obstacle 9, the matching bar 7 is inserted into the elongated hole 7a. It is guided and begins to retreat upwardly toward the retraction side 1b. In this state, when the closing operation further progresses, the detection element 6a of the entrapment prevention sensor 6 comes into contact with the obstacle 9 and is pressed as the matching bar 7 retreats, and the door drive device (not shown) is immediately activated. The power supply circuit is stopped or switched to rolling control, and damage to the obstruction due to being caught is prevented, thereby improving the safety of the horizontal sliding doors 1, 1'.

After that, when the obstacle 9 is removed, the detector 6a of the entrapment prevention sensor 6 returns to a steady state, the power circuit of the door drive device is switched to control the closing operation, and the side-pull doors 1, 1 When the closing of ' is resumed, the matching bar 7 again descends along the elongated hole 7a due to its own weight and returns to the state protruding from the door tip portion 1a.

Note that in this embodiment, the upper rail 3 of the opening 2
Although the horizontal sliding doors 1 and 1' are shown as being suspended from a hanging wheel 4 engaged with a hanging wheel 4 via a hanging fitting 5, the present invention is not limited to this, and may be adopted for horizontal sliding doors that run on a lower rail. It can also be applied to draw and single-opening doors.

[Effects of the invention] In short, the present invention has a plurality of face plates arranged horizontally and movably suspended, and is equipped with a pinch prevention sensor to detect obstructions caught between the face plates. In the horizontal sliding door, a matching bar that can move forward and backward between the adjacent door end side and door end side of the face plate is installed, and a detection sensor for preventing jamming is installed on the side end surface on the side where the matching bar is installed. Since the child is protruded so that it can come out and go out freely, and is connected to the obstruction between the face plates, the above-mentioned connecting bar is retracted, so when the obstruction prevention sensor detects the obstruction, the horizontal sliding door can be stopped or Even though it can be rolled, the gap between the closed face plates can be reliably covered by the closing bar without interfering with obstacle detection, and drafts can be removed from the joint of the closed door. This has the extremely useful practical effect of eliminating inconveniences such as air being blown in or people peeking inside, and making it possible to improve both the safety and closing performance of horizontal sliding doors. be.
