Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a door temporary stop mechanism in a self-closing door that can temporarily stop the door at a desired intermediate position during opening.

[Prior Art] Self-closing doors, which can be opened manually and then automatically closed using a spring or power, are commonly used. However, although this self-closing door is equipped with a mechanism that temporarily stops the door only when it is fully opened, there is no one to date that allows the door to temporarily stop at a desired position halfway through opening.

[Problems that the invention aims to solve] In hospitals, etc., the openings in hospitals need to be large in order to take in and out beds, etc. Therefore, the above-mentioned large opening is preferable as it provides sufficient room for wheelchairs to enter and exit, but it does not need to be wide for the entrance and exit of crutch users or healthy people, and an opening in the middle of this opening (approximately 80 cm opening) is sufficient. However, as mentioned above, the entrance is large and the door is installed so that it stops only when it is fully opened, so the door must be opened wider than necessary for general traffic, which requires wasted effort.

[Means for solving the problem] In view of the above-mentioned circumstances, the present invention provides a self-closing door with a locking roller pivotally supported by a support piece at the upper end of the door, and the support piece. A starting piece is placed at a distance from the starting piece, and the upper frame on the bottom side of the door is equipped with a cylinder with one end pivoted, and the tip of the rod from the cylinder connected to make one end swingable. A self-closing type that is equipped with a locking device consisting of a supported locking arm, and when the door is opened, the locking arm is rocked by an activation piece to temporarily lock the locking roller and stop the door. It provides a temporary stop device for the door.
The purpose of this is to arrange the activation piece and locking roller of the temporary stop device at a desired position in the middle of the door so that the stop mechanism can temporarily stop the door in the middle of the opening, thereby eliminating waste.

[Example] Next, an example of the door temporary stop device according to the present invention will be described with reference to the accompanying drawings.

Reference numeral 1 is a self-closing door, and the upper end surface of the door 1 is provided with pivot pieces 3, 3a, which support hanger cars 2, 2a, at two places in the front and back, and is closed by a rail 5 installed horizontally in a frame 4 at the top of the entrance. The hanger cars 2, 2a are suspended so that they can be opened and closed.

The door 1 is further provided with activation pieces 6, 6a and a locking roller 7 at two locations on the upper end surface: one where the door stops when the door is fully opened, and the other where the door 1 stops at a desired intermediate position (for example, at an opening of about 80 cm). , 7a are provided, respectively. This starting piece 6,6
The relationship between a and the support pieces 8 and 8a is such that they are spaced apart from each other so that no problem occurs when a locking arm 12, which will be described later, locks the locking roller 7 or 7a. Said 2
Of the support pieces 8 and 8a at these locations, the support piece 8 on the side of the fully open stop position of the door 1 falls down toward the door end and stands up in the groove 9 provided along the longitudinal direction on the upper end surface of the door 1. Sometimes it is received at the inner end of the groove 9, and one end is pivoted to prevent it from falling in the direction of the door tail, and the support piece 8 is provided with a spring 10 biased in the direction of restoration.

The two actuating pieces 6, 6a are each provided with projecting parts 15, 15a extending in the lateral direction at the upper part thereof, and are slightly inclined toward the door end.

The frame 4 is provided with a stop mechanism A that provides a temporary stop when the door 1 is opened at the upper position of the rail on the door end side when the door 1 is fully closed. This stopping mechanism A includes the case 11
The locking arm 12 has one end pivotally supported on the distal end side of the locking arm 12.
It consists of a hydraulic cylinder 13 with one end pivotally supported at the rear of the case 11, and the tip of a rod 14 from the hydraulic cylinder 13 is connected to a locking arm 12 to perform a buffering and restoring action.

The locking arm 12 is configured such that when the rod 14 is extended, the most advanced position level is slightly higher than the hanger wheel 2 and the locking roller 7.
In addition, the locking arm 12 is located at a position lower than the upper ends of the activation pieces 6, 6a, and the locking arm 12 is slightly curved so that the locking rollers 7, 7a can be easily locked. Furthermore, a protrusion 12a is provided on the side of the tip, which abuts against the protruding parts 15, 15a of the activation pieces 6, 6a.

[Function] As is clear from the above configuration, the present invention has the door 1
The self-closing door is suspended from a rail 5 installed horizontally above the entrance via hanger wheels 2 installed at the front and back of the upper end surface of the door 1, and can be moved along the rail 5 to open and close. When the door 1 is opened from the fully closed position shown in FIG. It hits the tip side protrusion 12a of the locking arm 12 of the temporary stop mechanism A provided at the upper part of the door end side (see Figs. 2 and 3), and the door 1
When the locking arm 12 is opened, the locking arm 12 is moved by the protrusion 12a to the actuating piece 6, with the locking arm 12 centered around the supported shaft P.
The locking arm 12 is guided along the inclined surface of the overhanging portion 15a of FIG. 1A, and begins to swing about the axis P against the cylinder 13 until it reaches the state shown in FIG. 4 (see FIG. 5). At this time, when you release your hand from the door 1, a self-closing force is applied to the door 1, and the locking arm 12 locks the locking roller 7.
The door 1 is temporarily stopped by being locked by the locking arm 12 until the rod 14 is extended by the action of the hydraulic cylinder 13. Rod 14 is cylinder 13
When the locking arm 12 is extended by the locking roller 7, the locking arm 12 is pushed upward around the axis P, swings, and is slightly separated upward from the locking roller 7, and the locking arm 12 is released and automatically closed by the self-closing force. .

Also, when opening door 1 to the fully open position, door 1
is opened to the intermediate position, and when the door 1 is further opened in the opening direction from the position where the locking arm 12 locks the locking roller 7a, the protrusion 12a at the tip of the locking arm 12 opens.
passes under the overhanging part 15a of the activation piece 6a, and when it is further opened in the opening direction, the locking arm 12 is completely opened with the rod 14 not extended, so the tip of the locking arm 12 is fully opened. Push the locking roller 7 of the support piece 8 on the door end side of the door 1 installed at the side stop position (see Fig. 6), and then move the support piece 8 forward toward the door end with the pivot support as the center, and fold it into the groove 9. (See Figure 7) Passing through the support piece 8, the rod 14 of the locking arm 12 moves to an extended state, but at this time, the protrusion 12a at the tip of the locking arm 12 hits the activation piece 6 (see Figure 2). Reference) Locking arm 1 in the same way as the intermediate position opening
2 is advanced against the cylinder 13, the locking arm 12 is swung, and the locking roller 7 is temporarily locked and stopped until the rod 14 is extended (see Fig. 4), and when the rod 14 is extended, it is locked. When the condition is cleared, the door will close automatically.

In this embodiment, the activation pieces 6, 6a and the locking rollers 7, 7a are provided at the intermediate portion and the fully open position, but the invention is not limited to this, and the activation pieces and the locking roller may be provided at any position. Of course, it can be latched at a desired position.

[Effects] As described above, the present invention uses a support piece that pivotally supports a locking roller at the upper end of the door, and an activation piece arranged at a distance from the support piece in a self-closing door to stop the door when the door is fully opened. They are installed in two positions, one at the stop position and the other at the middle position, and the upper frame on the bottom side of the door is equipped with a cylinder with one end pivoted on the case and the tip of the rod from the cylinder connected. Moreover, a stopping mechanism is provided, which consists of a locking arm with a protrusion on the tip and one end pivoted so that it can swing, so that when the door is opened, the tip of the locking arm moves to the side when the door is opened at the intermediate position and the fully open position. This causes the locking arm to swing about the axis against the cylinder, causing the locking arm to lock and stop the locking roller until the rod is extended from the cylinder. Also, when the rod is extended, the locking arm releases the locking state, so the door closes temporarily with its own self-closing force.The door can be temporarily stopped at the desired open position, so it can be used even in wide entrances and exits. If the activation piece and the locking roller are provided at desired positions, it is convenient to open the door without unnecessary effort.

In addition, the structure is simple, with the activation piece and locking roller placed in the position where they stop on the door side, and the locking arm and hydraulic cylinder installed at the top, so there are fewer failures, and it can be used with conventional doors. It also has the advantage of being easy to install and use.
