Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is a double-sided, left-right opening/closing door device for residential doors, etc., which is an improvement on the double door device disclosed in Patent Application No. 175928 of 1982, and simplifies the holding mechanism of the upper and lower claw shafts. It is characterized by being able to aim at precision of operation.

Hereinafter, the present invention will be explained in detail with reference to embodiment figures.

A handle shirt 3.3' is mounted as a penetrating shaft in the vertical center position on both sides of the door 2 that fits into the door frame 1, and a handle 4.4 and handles 41, 41 are fixed at both front and rear ends, and the door is closed. 2, the wire guide wheels 5, 51 are fixed to the handle shaft 3.3', and the horizontal V-shaped wire guide tubes 6, 61 are fixed inside the wire guide wheels 5, 5+ inside the door. After tightening the bolts, drill holes that are continuous up and down at positions near both sides of the upper and lower horizontal frames 7, 71 of the door 2, insert the upper claw shafts 8, 8+ and the lower claw shafts 9, 91, and insert the upper claw shafts 8, 8+ and lower claw shafts 9, 91, Attach the end to the upper bearing 10.
10' and lower bearings 11 and 11', and the upper and lower wire tubes 12, 12' and the lower wire tube 13 are moved from the wire guide tubes 6.61 on both sides in the axial direction of the upper and lower claws.
．． Two wires 14 and 14' extended by 13"i and one end locked to the wire winding wheels 5 and 5' are inserted into the upper and lower wire tubes from the wire guide tube and locked to each upper and lower claw shaft. , a coil spring 15 is fitted to the tip of each wire 14, 14', and both ends of the coil spring are received by the rear end of the claw shaft and the wire tube, and the door 2 is mounted facing the wire winding wheels 5, 51 on both sides. A horizontal hole 16 is drilled in the vertical frames on both sides of the door, a box 17 is fixed to the outer end of the horizontal hole 16, a guide frame 18 is provided protruding into the door from the pock 17, and the guide frame 18 is fitted into the box 17. Bracket 2 of roller 19
A long plate 21 protruding backward from the box 17 is made to protrude from the hole in the box 17 along the guide frame 18, and its rear end is supported on the guide frame 18. A spring 22 is attached to the long plate 21 inside the box 17, and the roller 19 protrudes from the side of the door, a stopper plate 23 is provided at the rear end of the long plate 21 to protrude toward the front peripheral edge of the wire traction wheel, and the 1 engages with the stopper plate 23 at the front surface of the wire traction wheel. Left and right wire retractor holding mechanisms 25, 251 are provided in which a pair of model protrusions 24.24'' are protruded from the periphery in a vertically opposed manner, and are engaged with the upper and lower inner surfaces of the door frame 1, facing the tip of each pawl shaft. Stop hole 26
．． 26', locking holes 27, 27' are formed, and holes 28, 28' that match the rollers 19 of the holding mechanism 25, 25' are formed on the inner surfaces of both sides.

Note that 29 and 29' in the figure indicate the handle lock.

The effects of the invention will now be explained with reference to embodiment figures.

The uninvented opening/closing door mechanism is installed on the entrance door of a house or other room door to open and close the door from the left and right from the inside and outside. When the door 2 is closed, the coil spring 1 attached to the tip of each upper and lower wire 14, 14'
5 acts on and presses each pawl shaft, so that each pawl shaft protrudes from the upper and lower surfaces of the door 2 and locks into the locking holes 26, 26' and 27, 27 provided in the door frame 1. ．． '. Therefore, when a person located outside the front of the door 2 grasps the right handle 4 and rotates it clockwise or counterclockwise, the handle shaft 3 rotates together with the wire winding wheel 5 inside, and the upper and lower wires 14. 14' compresses the coil spring 15 at the tip and is wound around the wire winding wheel 5 and pulled, so the upper pawl shaft 8 and the lower pawl shaft 9 on the right side of the door are drawn into the door 2 and engaged. The wire retractor 5 is disengaged from the stop holes 26 and 27 at the same time.
A model-shaped protrusion 24 that protrudes from the front of the retractor due to the rotation of
Alternatively, the protrusion 241 passes through the stopper plate 23 protruding from the long plate 21 of the holding mechanism 25 while pressing inward, and the stopper plate 24 is attached to the rear end of the protrusion 24 or the protrusion 241.
3 engages to prevent reverse rotation of the wire winding wheel 5 and hold the upper and lower pawl shafts 8 and 9 inside the door 2, and when the door 2 is pulled in that state, the door 2 is moved between the upper and lower parts of the left side. Claw shaft 8
It can be opened to the right by pivoting at 1°91. Next, when the right-opened door 2 is closed, the roller 19 of the holding mechanism 25 protruding from the right side of the door 2 is pressed by the inner surface of the door frame 1, and the long plate 21 slides inward, causing the stopper plate 23 is disengaged from the rear end of the protrusion 24 or the protrusion 241 of the retractor, and the upper and lower pawl shafts 8 and 9 slide vertically by the elasticity of the coil spring 15 of the linked upper and lower wires 14 and 14', and are re-engaged. The wire traction wheel 5 is fitted into the locking hole 26.27 of the door frame 1 to maintain the closed state of the door 2, and as the wire 14.14' is pulled in the vertical direction, the wire retractor 5 rotates in the opposite direction and returns to its original position. The roller 19 of the holding mechanism 25 also returns to the hole 28 of the door frame 1 by the elasticity of the spring 220, and the stopper plate 23 also slides back to its original position.

- When opening by holding the pusher 41 on the left, the upper and lower pawl shafts 8 and 9 on the right become pivots to open the door to the left, and the handles 4 and 4' on both sides are also used on the inner surface of the door 2. This allows for double-opening operation. Furthermore, since the wire winding wheels 5, 5' are accurately held and released by the holding mechanism 25+25', there are few failures, the manufacturing cost is low, and the above-mentioned remarkable effects are achieved. be.
