Description

  The present invention relates to a door including a sliding door and a revolving door, and more particularly, to a kinetic energy capturing device that operates an environmentally friendly door that automatically opens and closes by its own weight through a mat without requiring electric power.

    Conventionally, automatic doors that are widely used require electric power, and there are door closers that automatically close manually opened doors, and a combination of a spring and a hydraulic damper is widely known. As for sliding doors, a combination of a spring and an air damper or a spring and a centrifugal brake is also known. Such a known closer is manually operated when the door is opened, and the door is opened against the resistance in the case of a damper type while compressing the spring, and the opened door is opened by the spring force of the spring. The door is gently closed against the resistance of the centrifugal brake. It also has a door that opens by pressing the air bag built in by stepping over the mat and sending it to the cylinder device via the connecting pipe, and two cylinders, one and the other, one built in the mat On the other hand, a device that can be used to open and close the door as an output of the energy intake device has been devised.

Japanese Patent Laid-Open No. 11-50736 JP-A-5-118180 Japanese Patent Laid-Open No. 11-159237 JP 2000-291326 A JP 2004-285792 A Japanese Patent No. 3906410 Japanese Patent Laid-Open No. 11-50736 Japanese Patent No. 2004-285792 JP-A-7-139594 JP-A-6-136780 Japanese Patent Laid-Open No. 58-054178 JP 2007-039997 A Japanese Patent No. 4569717 Japanese Patent No. 4687760 Japanese Patent Application No. 2010-175290

Therefore, the above-mentioned known closer needs to open the door against the resistance in the case of a damper type while compressing the spring at the time of opening, so opening the door becomes a considerable burden for disabled people, elderly people, or children, If the stored power setting is too small, the function stops and does not satisfy the function. Also, when the door is closed, if the resistance setting to the spring is small, the door closes at a high speed, which is often dangerous for the elderly, the disabled or children. In addition, since the closing speed is adjusted by a damper or a centrifugal brake, it is necessary to apply an excessive load that is temporarily divided by the energy due to the resistance, which is difficult to handle. Also, in the type that breaks through the mat, the air bag is made of an elastic body alone because it expands and contracts, and the secular change due to the environment is remarkable, so it is difficult to predict the life by strength calculation, and it is difficult to guarantee it as an industrial product. In addition, the automatic door using electric power requires standby electric power in addition to driving electric power, and further causes energy loss. In view of this, the present inventor has proposed an energy intake device that includes two cylinders, one is built in the mat, and the other is capable of using the energy taken in to open and close the door.

However, for example, when an elderly person or a disabled person is acting in a wheelchair, a large mat that can be ridden with a wheelchair is essential, and there is a possibility that multiple users may step through the mat at a time. And a large stepping load is required during operation.

In order to solve the above-mentioned problem, the weight of the mat 3 is counteracted by the weight of the weight 201 so that the load is applied in the direction opposite to the gravity load direction of the mat 3 so that the load is applied to the weight 201 via the wire rope 204, Provided is a labor-saving kinetic energy device that operates with a load.

In the invention according to claim 1 of the present application, the mat 3 is interlocked with the weight 201 via the wire rope 204 and the pulleys 202 and 203 are used. Provided is a labor-saving kinetic energy capturing device characterized by being installed.
That is, when trying to lift the heavy mat 3 that has been enlarged in accordance with various usage conditions to the initial mounting position before stepping with the spring 221, a large spring load is required, and when the mat 3 is stepped over, In order to compress, a large stepping load is required according to the amount of stepping. Therefore, the dead weight of the mat 3 is canceled using the dead weight of the weight 201 that is not affected by the amount of stepping, and is lifted to the initial mounting position before the stepping with a small and constant load regardless of the amount of stepping.

On the other hand, the present inventor has proposed a technique of a kinetic energy capturing device. (For example, refer to Patent Document 14). This technique uses the energy provided in the door 1 and the discharge chamber for discharging the fluid in the input cylinder 220 for inputting the energy provided in the mat 3 into the apparatus in order to use the kinetic energy generated by stepping through the mat. Provided is a device that outputs a kinetic energy that works through a hydraulic hose 2 and communicates with a pressure chamber that sucks and further compresses fluid in an output cylinder 205 that outputs and works outside the device. ing.

That is, according to the present invention, kinetic energy generated by a person's traffic is taken from the input piston 223 provided in the mat 33 and the output piston 207 is moved through the hydraulic oil 225. In the invention according to claim 1 of the present application, the following means may be further provided for weight reduction. The ratio of the input piston area b to the output piston area 207a is set to 1 or more, and the load on the output piston 207 due to the weight of the mat 33 is reduced by the ratio of the input piston area 223b / output piston area 207a.

In the invention according to claim 1 of the present application, when it is not desired to use a fluid, it can be transmitted only by a mechanism.

That is, the hydraulic oil 225 is not used for energy transmission, and the output piston 207 including the rack 229 is moved using the gears 230 and 231 and the rack 228 by the movement of the input piston 223 including the rack 227. The following means may be further provided for weight reduction. The input gear 251a and the rack 227 of the two-stage gear 251 having the integrated input gear 251a and output gear 251b in which the ratio of b to the gear diameter a is set to 1 or more are set so that the output gear 251b and the rack 228 are engaged. The load on the rack 228 due to the weight of the mat 3 is reduced by the ratio of the diameter 251b / diameter 251a of the load on the rack 227 included in the input piston 223.

Further, the invention according to claim 2 of the present application has two sets of one-way clutches 213 and 214, and a gear 211 that are provided so as to rotate integrally only in opposite directions in order to efficiently incorporate kinetic energy with respect to claim 1. 212, an output piston 207 having racks 215, 216, a device for capturing kinetic energy from both directions of piston reciprocation.

According to the third aspect of the present invention, the rack 215 or 216 connected to the output piston 205 is meshed with the gear 211 or 212 connected to the shaft 208, and the reciprocating motion is converted into rotational motion.

The greater the inertia, the more effective it is because it only turns in one direction. From the above description, the mat device as an energy capturing means efficiently captures kinetic energy without requiring electric power.
