Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for opening and closing a door by using a force applied to a foot plate.

[0002]

2. Description of the Related Art Conventionally, there has been an electric automatic door using a drive motor.

[0003]

The conventional automatic door has a limited structure because its structure is large and expensive. The present invention is mainly used for doors of houses and garages.

[0004]

[Means for Solving the Problems] A spring (2) is provided on the upper portion of a rack (1), and a raised foot plate (3) at the lower portion and the center of the rack (1) is fixed by a wedge (4), and Engage the gear (6) that works with the pulley (5) in the rack (1), install the belt (7) between the two pulleys (5, 5), and install it on the door (8) at the upper left and right two places. The wheels (9, 9) are provided, the wheels (9, 9) are mounted on the rail (10), and one piece of the belt is attached to the screw (1).
1) Fix with scissors. The present invention is a foot door opening / closing device having the above configuration.

[0005]

[Operation] When a person rides on the foot plate (3), the wedge (4) is pulled down, the teeth of the rack (1) rotate the gear (6) fixed to the pulley (5), and one piece of the belt (7) opens the door. Since it is fixed to (8), the door opens. When a person descends from the foot plate (3), the rack (1) is returned by the action of the pulling spring (2), the pulley is rotated in the opposite direction, the belt is returned, and the door is closed.

[0006]

First Embodiment A first embodiment of the present invention will be described below with reference to FIG. (A) The rack (1) should move up and down by about 5 cm, and the tension spring (2) should be attached to the upper part and screwed so that the wedge (4) should not be removed from the lower part. The rack is moved up and down by connecting the chain (4) and stepping on the foot plate (3) so that the foot plate (3) made of a material such as elastic plywood is not easily removed. (B) When the rack (1) moves, the gear (6) engaged with the rack (1) rotates, the pulley (5) rotates, and the rubber belt (7) hung on the pulley moves about 80 cm. (C) One piece of the belt (7) is fixed to the belt mounting portion of the wheel (9) with the screw (11), and when the foot plate (3) is stepped on, the door is opened sideways.

When the device of the present invention is used, put the foot on the foot plate (3) where the chain is connected and put the foot on it, and when the door is opened, the weight is applied to the foot plate and the passenger is stepped off from the foot plate. The door is closed by the action of the pulling spring (2), and thus the door is naturally opened and closed each time a person passes by.

[0008]

Second Embodiment A second embodiment of the present invention applied to a garage for an automobile will be described with reference to FIG. The same parts as those in the first embodiment are designated by the same reference numerals. What is different from the first embodiment is that the wire rope winding portion (12) winds the wire rope (13) in conjunction with the pulley (5). The wire rope (13) is passed through holes formed in both ends of the door (14) made of a light material such as urethane and is tied to a bent portion under the door. Since this embodiment is applied to the garage for automobiles, the tread is made of metal, and the belt (7) is extended to allow the vehicle to pass through with the pulleys spaced apart.

According to the method of use of this embodiment, when the rear wheel rides on the tread (3) when the vehicle is backed in the garage, the device is activated and the winding portion (12) of the wire rope is rotated to rotate the wire rope (13). The door (14) is pulled up while being folded, the front wheel follows the rear wheel, and the front wheel rides on the tread and backs as it is, and the door closes when the front wheel descends from the tread.

[0010]

[Third Embodiment] A third embodiment of the present invention will be described with reference to FIG. The same parts as those in the first figure are designated by the same reference numerals, and this embodiment is left-right symmetric.
The doors open one after the other so that both sides can be folded. (A) A spring (18) is provided below the arm protruding from the bevel gear (15), a foot plate (3) is covered on the arm, and the bevel gear (17) is fixed to the lower part of the rotating shaft (16). When the bevel gear (15) and the foot plate are engaged, the rotation shaft is rotated by about 90 degrees. (B) Fix the gear (19) to the upper part of the rotary shaft (16),
The small gear (20) is engaged with the pulley (21) to transmit the rotation, and the belt (7) is attached to the pulley in a figure 8 shape. It is fixed to the attachment part (23) of (3) with a screw. (C) The door (24) has two right and left (24a) and (24)
b) and two upper and lower parts are connected by a hinge (22) and bent at the center so that the door (24b) is fixed to the rotary shaft.

According to the method of use of this embodiment, when the user steps on the foot plate (3), the arm is lowered and the bevel gears (15, 17) are rotated, and the rotary shaft (16) is rotated by the gears (19, 20) to rotate the pulley (2).
1) The belt (7), which is rotated in the opposite direction and hung in the shape of a figure 8, exerts a force to open the door (24a) outward. At the same time, the rotating shaft (16) exerts a force to rotate the door (24b) outward, so that it can be smoothly opened and closed in conjunction with the movement of the belt. The broken line (25) represents the state in which the door is open, and when both sides are folded and opened in this way, it is easy to pass from whichever side comes and the present invention can be effectively utilized.

[0012]

Since the present invention is constructed as described above, it has the following effects. Since the door is opened by stepping on the foot plate, it is very convenient when both hands are occupied without using hands, and in the second embodiment, it is possible to enter the garage without getting out of the car. Both are far cheaper to produce than conventional automatic doors and remote control shutters, and economical because they do not use electricity.
