Description

[Detailed description of the invention]

The present invention relates to a control device that controls opening and closing of a door. . There are various mechanisms for opening and closing the adjustable doors, and there are various means for simultaneously operating a pair of adjustable doors. A bushel placed under a service table or shelf for handing over money, goods, etc., and designed to be activated by an operator seated behind the table with his hands free, for example by exercising his knee muscles. A device using a mechanism characterized by the following is known. Through a mechanism, the butschrond transmits motion to a pair of swivel doors, pivoting the swivel doors about a longitudinal axis to provide an unobstructed path to the other side of the service table for operations. When such muscular force is released, the door automatically returns to its original closed position due to the return movement of the mechanism actuated by a spring or the like. The present invention improves on the prior art and relates to a door opening/closing control device which is operated exclusively by automatic means activated by the will of an operator located, for example, behind a service table, in order to minimize the need for muscular strength. It is. The operation of the generally uninvented door-opening control device can be initiated by a slight movement of the operator's body, that is, the torso, without using the hands, so that the operator can relax and distribute the goods. You can carry out your own work such as giving money or receiving money. Once the handling is complete, the door should be opened so that the operator can move the body as well.

[This closes. A master switch or control switch is provided that energizes the air circuit prior to actuating the door. Various other objects and advantages will become apparent from the description below. The invention will be described in detail below with reference to the drawings. The embodiment shown in Figures 1-8 has a cam that transmits interlocking to the door or pair of doors via a flexible joint. This cam is actuated by the operator's muscular strength, i.e. by the knee or thigh below the service table with the operator's hands free, via a linear element such as a pushrod. When the door is opened, force is stored in the spring, and by removing the muscular force, this force acts to close the door. The code 0 indicates a small room that may be located, for example, at the front desk of a fast food restaurant, where take-out orders are typically placed for expediting purposes. The cubicle can also be fully or partially provided with a west light wall to provide visibility between the customers on the outside of the cubicle and the employees on the inside. A shelf or a horizontal shelf-like protrusion 15 is provided on the stand of the small room in direct contact with the front side or the customer side of the passageway formed for conducting business. This passageway shall be provided with a closing means such as a single or double door. Preferably, a pair of doors 20.20 are provided which are designed to swing about vertical hinges or pivots. A particular non-invention concerns the means for opening and closing the door 20, which is normally closed and is opened by the employee inside the cubicle when conducting business via the above-mentioned passageway. A door actuator is attached below the shelf 15. This device is
having a plunger rod or the like that can move forward and backward;
By applying a linear force to the plunger head 27 at the free end of the rond by moving a part of the employee's body, such as the knee or thigh, with the hands free for other purposes, You can do this Rondo without moving. Moving the plunger axially forward opens the door 20 via the transmission mechanism. This transmission mechanism is connected to the pivot 8 below the shelf 15.
1 crank 8
0 has a cam track 87 on its free arm 85. (
(See Figure 5) Anti-friction roller (antifrl, ct soil
A cam follower 40 , which has the shape of an i roller ) and is supported on a flange rod 25 , is placed on the cam track 37 . A robot 82 around which the crank 80 rotates is constituted by a stub shaft. The stamp shaft is keyed with a toothed sprocket housing 5 which operates a flexible coupling means such as a crank and a toothed belt 47. The flexible coupling means is wound around the pulley 50, 50, and the belt 47 rotates the pulley 50. An idler cylinder 52 is provided to isolate the adjacent healds 47. Therefore, when the sprocket t5 is rotated clockwise by the cam and crank, force is transmitted through the belt 47 and the pivot The door 20 is moved to the closed position (second to fourth
(see Figures 1 and 5) to the open position (see Figures 1 and 5)
A cam follower 40 is attached to a carriage 80 slidably disposed within a groove member 85 fixed to the lower part of the shelf 15 in order to transmit the phlegm movement from the O bush Z shrod 25 that swings to the cam. The roller bearing 68, which is supported by the shaft 65 supported by the carriage 80, has the limit 5 of the groove 85.
When the cam follower 40 is moved in the liJ direction by the plunger 25, the cam follower moves inside the groove 85 toward the carriage 8.
Since the roller bearing 68 engages with the limit flange 87 of the groove and slides with minimal friction, almost no muscular effort is required to open the door. A tension spring S□ fixed under the shelf at a point 82 is attached to the carriage 80 at a point 81. In order to open the door against this spring, a plunger 25 and a carriage 80 are used.
This spring stretches as you move the and forward. When the muscular force acting on the plunger is released, the spring Sl returns to its original position, each part returns to its initial position, and the cam rotates the crank clockwise to close the door. A compression spring S2 attached to the plunger shaft 25 at the rear of the carriage 80 acts as a buffer for the return of the carriage when the force is removed from the plunger 25 and the carriage and parts automatically return to their normal positions. functions as As can be understood from the above explanation, in the invention, the door is operated by electrical means, and the operation is completely free.
You can concentrate on business transactions over the counter. Such electrical means are applicable not only to the cam and bellcrank devices described herein, but also to a variety of other mechanical structures. FIG. 7a shows a control mechanism similar to the embodiment shown in FIGS. For this purpose, a geared reversible motor 200

Connect to. When the motor is energized and the actuator 202 is moved to the position shown by the broken line in the figure, the cam follower 40 and the carriage 80 to which the cam follower is attached move to open the door, as described above. The next energization of motor 200 engages the actuator to the position shown in solid line, thereby moving the carriage and follower 40 to close the door. Motor 200 is a reversible gear motor as is well known in the art, such as a 1776S Romb Tribe 1776S Metacle Corp. Industries, Inc.

- Tatea: The device shown in Figure 6.i7a can automatically operate the window either by human muscle force generated by pressing the lancer 27 or by electrical force based on the energization of the motor 200. I can do it. If only automatic operation is desired, the return lever 51 can be used so that continuous energization of the motor 200 can provide interlocking of the carriage.
In addition, the plunger 7a (9) may be omitted. As described above, a simple linear force applied by the operator below the counter can cause it to oscillate about a longitudinal axis or a pair of parallel axes, while leaving both hands free to work over the counter. A simple mechanism for opening and closing an attached door or pair of doors has been described. Substantially the same or other substantially similar mechanism may be used in place of muscle power, and the operation may be performed automatically by electrical means. Note that the above-mentioned embodiments show only a few examples of the present invention, and the invention is not limited to these embodiments, and various changes can be made within the scope of the claims.
