JPS603249Y2 - Double-sided, left/right double door device - Google Patents

Description

[Detailed Description of the Invention] Since the entrance door of a house or the door of a car opens on one side, the opening/closing operation is easily restricted.

Therefore, the applicant developed a device that could open entrance doors, automobile doors, etc. from both the left and right sides from the inside and outside, and filed an application (Patent Application No. 2435 of 1981). Since the mechanism for operating the shaft is complex, it has the disadvantage of being prone to failure.

The present invention relates to the creation of a left/right double door device, which is characterized by simplifying the mechanism for operating the pawl shaft, which is the pivot of the door, and preventing the occurrence of breakdowns, etc., for the purpose of eliminating the above-mentioned drawbacks. It is.

Hereinafter, the configuration of the present invention will be explained with reference to embodiment figures.

A handle shaft 3.3' is mounted as a penetrating shaft from the front to the back in the vertical center position near both sides of the door 2 which is fitted into the door frame 1, and the handle shaft 3,3'
A handle 4 is attached to both ends of the operating frame 5, 5', and the center position of the operating frame 5, 5' is fixed vertically to the handle shaft 3°3' in the door 2. Rod 6
, 6 and the connecting rods 6', 6' are loosely connected, and the pawl shafts 7, 7 and the pawl shafts 7', 7 are inserted into holes opened on both sides of the upper and lower surfaces of the door 2.
An operating rod 10 in which the guides 8, 8 and 8', 8' are loosely fitted into each other, and the guides 8, 8 and 8', 8' are fixed in the door 2 vertically facing each axis, and a spring 9 is fitted in each guide. .10 and the operating rods 10', 10' are loosely connected to each pawl shaft, the operating rod 10.10 and the connecting rod 6.6 are loosely connected, and the operating rod 10.10 is loosely connected to the connecting rod 6.6.
', 10' and connecting rods 6', 6' are loosely connected, and the lower connecting rod 6
．． 6', a locking pin 11 is provided protruding from the front and back, and the locking step 1 is provided at the upper end of the opening to form a C-shape in plan view.
2 is formed into a locking frame 14, 14' with a tapered surface 13 provided below the locking step 12, and is locked to the pin 15, 15' inside the door at the inside position of the connecting rod 6°6'. Frame 14, 14
The lower end of ' is pivotally connected, and one end of a V-shaped spring 16.16' provided inside the locking frame 14.14' is connected to the locking frame 14,
14' and press it, connect the tapered surface 13 with the rod 6
, 6', and a hole is provided at the center position of the outer surface of both side frames of the door 2, and a roller with a bracket 17.1 is installed.
7' and the connecting rods 18, 18' protruding inward from the brackets of the rollers 17, 17' are connected to the locking frame 14,
A stopper 19 is attached to the base of the connecting rod 18 and 18', and locking holes 20, 20 are provided in the upper and lower inner surfaces of the opening of the door frame 1, vertically opposing each claw shaft. Stop hole 20
', 20' is made to open holes.

Next, the effects of the present invention will be explained with reference to embodiment figures.

When the door 2 is fitted into the door frame 1 and closed, the claw shafts 7.7 and 7 protrude from the upper and lower surfaces of the door 2.
The tips of ', 7' are fitted into the locking holes 20, 20 and locking holes 20', 20', respectively, on the inner surface of the door frame 1 facing each other.

Therefore, when opening the door 2 to the left from the indoor side, which is the front of the door 2, grip the right handle 4 and rotate the handle shaft 3 clockwise about 45 degrees. The fixed operating rod 5 rotates, and the operating rods 10, 10 with springs 9 and the pawl shafts 7, 7 are mutually pulled in the direction of the handle shaft 3 while resisting the elasticity of the spring 9 via the connecting rods 6, 6. The tip of each pawl shaft is disengaged from the locking hole 20° 20, and as the operating rod 5 rotates, the lower connecting rod 6 moves upward while the locking pin 11 slides on the tapered surface 13 of the locking frame 14. The locking step 12 of the locking frame 14 holds the claw shafts 7, 7 in a disengaged state when the operating rod 5 stops rotating. 2 is opened by rotating it around the claw shafts 7', 7' on the left side.

When the door 2 is opened, the locking frame 14 is pressed by the spring 16, and the roller 17 connected by the connecting rod 18 is released from the pressure from the inner surface of the door frame 1, so that the stopper 19 of the connecting rod 18 is pressed against the roller 17. The roller 17 is rotated a little until it comes into contact with the back side of the frame, causing the roller 17 to protrude a little from the side surface of the door 2.

Next, when the door 2 is closed, the roller 17 protruding from the side surface of the door 2 comes into contact with the inner surface of the door frame 1 and is pressed, so that the locking frame 14 connected via the connecting rod 18 engages the pin 15. The locking pin 11 of the connecting rod 6, which rotates in the opposite direction as the center and the restoring elasticity of the spring 9 acts downward, is connected to the locking frame 14.
The levers 10 and 10 with the upper and lower springs 9 are respectively slid in the vertical direction by the restoring elasticity of the springs 9, and the tips of the claw shafts 7.7 are disengaged from the locking steps 12. It engages with the locking holes 20, 20 of the body 1 to maintain the closed state.

Also, while gripping the left handshake 4 and rotating the handle shaft 3', insert the tips of the claw shafts 7', 7' into the locking holes 20',
The door 2 can be opened to the right by disengaging from the door 20' and rotating around the pawl shafts 7, 7 as pivots, and the door 2 can be opened to the right or left in the same way from the outside, which is the back of the door 2. It is something.

A lock pin is provided at a position below the handle 4 on the front surface of the door 2 facing the indoor side to prevent the movement of the operating rods 5, 5'.
If the operating rod is locked from the indoor side as necessary, the door 2 cannot be opened from the outside, and the opening can be achieved by cutting the rollers 17, 17' with a file, which takes time and effort to cut the claw shaft. In short, it also prevents theft, and as a double-sided, left/right opening door, it can be effectively used not only as the entrance door of a house, as a car door, but also as a door for a large refrigerator or freezer car, and has the remarkable effects mentioned above. It is something that plays.
