この発明は、公知の弾機を利用して直線上を往
復する扉の作動力を的確に調速し得る制御装置に
関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a control device that can accurately control the operating force of a door that reciprocates on a straight line using a known bullet.
従来、開放した扉を電気、油圧、空圧などの外
力を用いずに閉鎖させる手段として、開放時に蓄
えた復帰用のエネルギーを閉鎖用に放出するため
に各種弾機(渦巻きばね、コイルばね)や分銅
(錘)が多用されてきた。 Conventionally, as a means to close an opened door without using external force such as electricity, hydraulic pressure, or pneumatic pressure, various types of elastic devices (spiral springs, coil springs) are used to release the energy stored for return when opening for closing. and weights have been widely used.
しかしながら、前者は扉の開放距離が進む程弾
機の抵抗が累増して進行が重くなり、遂に進行が
停止するという難点がある。 However, the former has the disadvantage that the farther the door is opened, the more the resistance of the ammunition increases, making progress harder and eventually stopping.

大な押進力を労するなど実施不適の重大欠点を有
していた。 In addition, the latter, the emergency door disclosed in Japanese Utility Model Publication No. 12348/1980, requires troublesome work to dig down the weights to the bottom of the floor on the side pillar side if the transition distance is long, and This had serious drawbacks, such as the need to use a weight weighing more than the weight of the door, making it unsuitable for opening heavy doors, such as requiring a great pushing force.

散見しない。 The door check disclosed in Japanese Patent Publication No. 53-48022 was provided as prior art;
Since the spiral spring (mainspring) is installed on one side of the reel shaft via a reduction gear mechanism, and the governor with a speed increase gear mechanism is installed on the other side via a pin and clutch, winding of the mainspring is done at the door. As the opening progresses, it gradually becomes heavier, and on the other hand, when the door is closed, due to the characteristics of the mainspring, it rapidly expands inside the case, creating frictional resistance, which stops rewinding and prevents the door from closing completely, and the reel shaft. If the load concentrates on the pin and it breaks or bends near the base, the regulating function will be disabled and the door will rapidly (energize).
I've never seen it in the market, as it's dangerous because it's closed.

The opening/closing mechanism disclosed in the publication is attempted to temporarily prevent the retracting movement of the hanging door by using a one-way lock by pressing a friction roller while elastically contacting the outer periphery of the reel. (Roller and reel) are circular and have point contact, and controlling the rotational torque acting on the reel side by bullet restoration is possible even if a friction roller attached to another rope end is always clockwise to the guide rail. If it is in elastic contact with the reel shaft, it is impossible to unwind it, and therefore the unwinding motion of the constant force spring, which is the main ammunition, returns while being energized. The opening/closing mechanism becomes dangerous, similar to when the speed regulating function is lost.

本的技術として援用しているものである。 This invention was invented in order to solve all the problems of the prior art and prior art described above, and was disclosed in Japanese Utility Model Publication No. 12348/1983, which was filed earlier by the same inventor as this inventor. The return biasing force of the suspended door is controlled by the governor and the door is closed at a slow speed, and in the event of a fire, a solenoid is activated to release the door opening latch in response to smoke or heat, as described above. The technical idea of configuring the door to slowly close, and the earlier application by the same inventor as this invention, which was used in a well-known window opening/closing device as part of the opening/closing device in buildings like the hanging door. Jigashiaki who was
Publication No. 52-123439 (Utility Model Publication No. 54-49148) states,
The technical idea is disclosed in the specification and drawings, in which a constant output spring wound in an S-shape is housed in a case, and the return energy stored during winding is released during unwinding and used for opening/closing movement. Both of these prior art techniques are incorporated into the constituent elements of this invention as basic techniques.

ある。 Therefore, this invention does not use weights or energy from electricity, hydraulic pressure, pneumatics, etc. that is prohibited by the Fire Service Act, and makes full use of the characteristics of the well-known constant force spring to move the door forward in one direction. A labor-saving method that allows the door to be reliably closed while controlling its speed by using the reasonable and conventional principle of rewinding the winding distance from one drum to the other drum, that is, the winding distance equivalent to the forward movement distance of the door. The objective is to provide the market with an extremely versatile control device at a low price.
この発明を扉の作動制御装置として実施した実
施例を以下図面に基いて説明する。 An embodiment in which the present invention is implemented as a door operation control device will be described below with reference to the drawings.

後進するものである(第1図および第2図)。 In the first illustration, a cable 5, one end of which is tied to a fastener 3 erected at the upper end of the door 2, is used for both operation and operation, which is the main part of this invention, through a idler wheel 4 on the upper deck side. It is suspended in an actuating box C so that it can freely appear and retract, and when the door 2 moves forward, the fastener 3 releases an electromagnetic release 7 as shown in the second figure.
The door 2 temporarily stops due to occlusal restraint. When the pull cord 6 is lowered or the clasp 3 separates from the restraint of the electromagnetic release 7 due to heat or smoke, the door 2
The robot automatically moves backward in the direction approaching the operation box C side (Figures 1 and 2).

る。 The reciprocating movement of the door 2 is performed manually when opening, and when closing is performed using the return energy regulated by a governor device (described later) based on the characteristics of a well-known constant output spring inside the operation box C. However,
The arrangement of the passageway (corridor) at the opening varies depending on the design of the building. It may be arbitrarily placed on the upper deck side in a most convenient manner.

11a側に螺止固着する。 Next, inside the operation box C, as shown in the third figure, there is a two-stage drum 11 on one side of which the rope 5 can be wound up and unwound freely around a narrow body 11C, and adjacent to which a flange 11b is formed on the wide body 11a. is rotatably supported,
Another auxiliary drum 10 is rotatably supported at an appropriate interval, and a known constant force spring 1 is preliminarily attached to the auxiliary drum 10 in a naturally tightly wound manner without fixing the end portion to the door 2. The thick body 11a of the other two-stage drum 11 is wound several times longer than the traveling distance.
It is turned over to the side and stretched in an S-shape, and its end is fixed to the thick body 11a side with screws.

and a large gear 15, and another large gear 15 which is arranged to interlock with a pinion 16 on the same axis as the large gear 15.
It is connected to the end side of the shaft 12 of the stage drum 11, and linked to the second stage drum 11 side as a so-called speed increasing gear mechanism (FIGS. 3 and 4).

ものである。 Governor device A shown in FIGS. 5 and 6
In detail, when the left and right bell cranks 19 installed on the drive shaft 14 are expanded as shown by the arrows due to the sudden rotation of the drive shaft 14 and press the end of the brake shoe 21 with a lever action, the spring 20 is released. The brake shoe 21 is compressed and lowered to lower the retainer 22.
Pressing friction is generated on the lower side of the drive shaft 14, and the braking force is small when the drive shaft 14 is at low speed, but when the drive shaft 14 speeds up, the above-mentioned frictional force is generated strongly to control the speed. It is designed to be effective.

ある(第5図および第6図)。 In addition, the spring 20 that always presses the retainer 22 against the brake shoe 21 side can have its free length changed arbitrarily by means of a screw 23, and is constructed so that it can be adjusted from outside the control box C with a single screwdriver. Therefore, the rotational force of the drive shaft 14 can be freely changed by adjusting the degree of pressure contact of the retainer 22, so that the return force of the constant output spring 1 generated on the second-stage drum side is accelerated. Gear train B for
This structure is such that the torque that causes the drive shaft 14 of the governor device A to rotate at a high speed can be buffered and the backward speed of the door 2 can be reduced (FIGS. 5 and 6).

る。 This invention has the above-mentioned configuration, and its usage is generally divided into reciprocating movements of manual opening (forward movement) and automatic closing (backward movement) of the door 2. In other words, in the former case, the door 2 is operated by hand. When the multi-purpose operation box C is moved forward in the direction away from the side, the fastener 3 installed on the upper side of the door is wound in advance for a longer distance than the traveling distance of the door.
When the rope 5 is successively pulled out, the thick body 11a adjacent to the narrow body simultaneously rotates in the direction in which the rope 5 is pulled out. 1 is another sub-drum 1
Thick body 1 is pulled out from 0 in an S-shaped inside out direction.
It is wound up by 1a and successively generates return energy.

閉鎖されるからである。 When the door advances the maximum distance and the tip of the fastener 3 fits into the electromagnetic release 7, the two engage and are restrained, and the door 2 stops against the return force. I installed release 7,
For example, when the door 2 is used as a fire door, even if it is unattended at night, when a fire occurs, the door's stop restraint is automatically released by the action of a sensor that senses heat or smoke, and the constant output spring 1 is returned to its original position. This is also because the door automatically closes when the speed is controlled, preventing the spread of flames. During the daytime under manned conditions, when the door is stopped, the electromagnetic release 7 and the fastener 3 are disengaged by lowering the drawstring 6, and the door 2 is automatically closed by the return movement of the constant output spring 1 as described above. This is because that.

が自動的に行われるものである。 Next, when the door 2 starts to automatically close using the two operating methods described above, the constant force spring 1, which had been pulled out by the transition distance of the door, returns to the original sub-drum 1.
In order to return to the 0 side, the two-stage drum 11 is sequentially biased and accelerated to start rotating, and at the same time, the cable 5 that has been pulled out from the narrow body 11C is wound up. The energy of the constant output spring, which is sequentially accelerated by a reasonable configuration in which the speed increasing gear train B is interposed between the drive shaft 14 of the governor device A, causes the drive shaft 14 at the end to rotate at high speed. Therefore, due to the above-mentioned special speed adjustment force of the governor device A and interlocking of the gear train B, the shaft 12 of the two-stage drum changes to a slow speed state, and the door can be quietly retreated until it is completely closed. It is. Therefore, the backward speed of the door remains slow and does not change until the moment of closing, and there is no rapid advance at all, so there is no risk of damage to surrounding members or the door due to impact, making it extremely safe. The door closes automatically.

る。 By taking advantage of the characteristics of constant-output springs that have been used for a long time, the resistance when moving forward by manual operation is always kept constant regardless of the distance traveled, and when retreating, the return biasing force of the ammunition is sensitive. This is a door operation control device that automatically closes with a speed regulating buffer.
When manually opening the door, the clasp engages the electromagnetic release and stops temporarily, while the clasp disengages the electromagnetic release both by manual pull cord operation in a manned state, and even in an unattended state if a heat/smoke detector is used. Since the door can be closed automatically at a slow speed, there is no damage to the area around the door due to the impact when it closes, and unlike complicated equipment such as electricity or hydraulics, there is no need for cumbersome operations, daily inspections, or even power outages. , does not cause unexpected failures such as oil leaks, and can be quickly controlled with a single screwdriver from outside the operation box.Overall, it is an extremely simple manual operation, and the rest is automatic. Because the closing function operates safely and smoothly, no special operating skills are required.
In addition, it has a highly labor-saving effect, as consumption costs after installation are almost unnecessary in addition to daily inspections, and electricity and oil, which are unsuitable energy sources according to fire regulations,
It is equipped with functions that allow it to be fully used as a disaster prevention device that is fully compatible with manual conditions excluding air, etc.
