A door opening / closing device according to the present invention is a door opening / closing device using foot-operated pedals provided in the vicinity of the door on both floors sandwiching the door. The pedal is provided with a recess, a lock rod that penetrates the floor that can enter and leave the recess, and a spring that is connected to the lower part of the lock rod and constantly presses the lock rod upwards. It is characterized in that the lock rod linked to the pedal is released by stepping on and the door can be opened and closed.

In the door opening / closing device of the present invention as defined in claim 2, there are provided guide grooves which are inclined upward from the lower end of the recess of the door toward both outsides of the door, and when the door is closed, the lock rod is smoothly moved. It is characterized in that it descends along the guide groove.

[0009]

According to the door opening / closing apparatus of the present invention as defined in claim 1, there is provided a recess on the rear surface of the lower end of the door on the opening / closing side, a lock rod penetrating through the floor capable of entering and leaving the recess, and further connected below the lock rod. A spring that always pushes the lock rod upward is provided, and the lock rod linked to the pedal is released by stepping on the pedal so that the door can be opened and closed. , You can open the door by pushing the pedal with your toes to unlock the door even when both hands are blocked by poking the cane.

Further, in the door opening / closing device of the present invention according to claim 2, guide grooves are provided which are inclined upward from both lower ends of the recess of the door of the door opening / closing device according to claim 1 toward both outer sides of the door. When the door is closed, the lock rod smoothly descends along the guide groove, so even when closing the door, push the door with your arm or body without using your hands to close the door. It can be locked.

[0011]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a sectional view showing an example of a door opening / closing device of the present invention according to claim 1. In FIG. 1, reference numeral 10 denotes a door opening / closing device, and the door opening / closing device 10 is configured based on a mechanism described below.

Reference numeral 1 is a door provided in an opening of a wall of a building. Openings 2a and 2a are provided on both sides of a floor 2 with the door 1 near the opening / closing side of the door 1 sandwiched therebetween. There is. The opening 2a is provided with pedals 3 and 3 with its head slightly out of the floor surface 2, and vertical rods 3a and 3a extend vertically downward from the pedals 3 and 3.

The vertical rods 3a, 3a are designed so that their vertical movement is smoothly guided by the cylindrical guides 3b. Further, a horizontal rod 4 that connects the vertical rods 3a and 3a is provided from the middle of the vertical rods 3a and 3a.

The vertical movement of the horizontal rod 4 is performed by stepping on the pedal 3 and ascending and descending the vertical rod 3a. Therefore, the guide 3
Long grooves 3c, 3c in the vertical direction are provided on the side wall of b.

A lock rod 5 penetrating through the floor 2 at the upper end of the center of the horizontal rod 4 and capable of entering and leaving a recess 1a provided at the lower surface of the lower end of the door 1 is vertically connected. Further, the horizontal rod 4 is pressed upward so that the lock rod 5 is fitted in the recess 1a of the door 1, and the door 1 is always locked. Therefore, the spring is attached to the lower end of the central portion of the horizontal rod 4. 6 is provided, and this spring 6 is held by a holding tool 6a at the lower end.

[Operation of Embodiment] Door opening / closing device 1 of the present invention
In 0, the door 1 is always kept in a locked state for safety. By stepping on the pedal 3, the door 1 can be opened and closed from any side of the door 1 without using a hand. You can do it.

That is, when the pedal 3 is stepped on by the foot, the vertical rod 3a is guided by the guide 3b and smoothly descends. At this time, the horizontal rod 4, which is integrally connected to the vertical rod 3a, moves the spring 6 along the long groove 3c of the guide 3b.
While pressing, descend downward. Therefore, the lock rod 5 integrally connected to the horizontal rod 4 descends by the same distance as the pedal 3 descends, and can escape from the recess 1a of the door 1. In this state, the door 1 is left unlocked, so that it can be opened and closed from either side of the door 1 without using a hand, by merely pushing lightly with the arm or body.

FIG. 2 is a sectional view of a main part showing an example of the door opening / closing device of the present invention according to claim 2. In FIG.
From the lower end of the recess 10a of the door 10, guide grooves 10b and 10b are provided which are inclined upward toward both outsides of the door 10, and when the door 10 is closed, the lock rod 5 smoothly moves along the guide grooves 10b and 10b. It is designed to descend. Therefore, even when the door is closed, the door can be closed and locked by pushing the door with the arm or body without using the hand.

In the door opening / closing device of the present invention, in the embodiment, the door locking mechanism is provided only at the lower end of the door, but the connecting rod and the connecting wire interlocking with this mechanism are also used at the upper end of the door. A lock rod may be added.

The structure and structure of the lock mechanism in the door opening / closing device of the present invention are not limited to the above-mentioned embodiment, but include modifications as long as they do not depart from the spirit of the present invention. For example, in the above embodiment, the pedals provided on both sides of the door are arranged so that when one pedal is depressed, both pedals work together, but only the pedals on the necessary side are It may be a mechanism that interlocks with the lock rod.

Further, the spring that constantly pushes the pedal and the lock rod upward may be provided below the pedal instead of directly below the lock rod so that the pedal and the lock rod are always pushed upward.

Further, in the door opening / closing apparatus of the present invention, the lock rod is provided only at the lower end of the door, but this lock rod is also provided at the upper end so that the upper frame of the door is provided with a recess so that the door can be locked up and down. Alternatively, the pedal and the upper and lower lock rods may be connected by a rod or a wire so that the pedal and the upper and lower lock rods are simultaneously linked.

[0023]

According to the door opening / closing apparatus of the present invention, a recess is formed on the back surface of the lower end of the door on the opening / closing side, a lock rod penetrating the floor that can enter and leave the recess, and further below the lock rod. It has a spring that constantly pushes the lock rod upwards, and when the pedal is depressed, the lock rod linked to the pedal is released and the door can be opened and closed. You can open the door by pushing the pedal with your toes and unlocking the door when you are walking or when you are poking a cane and both hands are blocked.

Further, in the door opening / closing apparatus according to the present invention as defined in claim 2, guide grooves which are inclined upward toward both outsides of the door from the lower end of the recess of the door of the door opening / closing apparatus according to claim 1 are provided. When the door is closed, the lock rod smoothly descends along the guide groove, so even when closing the door, push the door with your arm or body without using your hands to close the door. It can be locked. Therefore,
It is suitable as a door opening / closing device.
