Figure 3b is a vertical touch member (40m1) also has a long bar shape, the upper portion is provided with a support portion (40s) to be evenly transmitted to the displacement means 30 in the case of pushing or pulling.

In addition, the one-touch door opening and closing device according to the present invention according to the present invention is preferably provided with a locking means like a normal door.

6F, 6G, and 6H including FIGS. 6A to 6E are views related to the locking means for the one-touch door opening and closing apparatus according to the present invention.

The locking means 60 is installed through the through hole 48A of the first disk 42A and has a lock lever 61 having a return spring 61s therein, a lock 63, a key bundle 65, and the like. It consists of.

When the upper surface of the locking end portion 63a of the clamp 63 is pressed by the end pressing projection 61a of the locking lever 61 (see Fig. 6E [A]).

The catch 63 is pivoted about the tongue projection 46B of the second disc 42B so that the lock end 63a (see FIG. 6E [A]) is provided.

The second swing body 47B having pinholes 47a 'are respectively prevented from being assembled through the coupling pins in the holes 45a "and 45b" formed in the coupling sleeve 45b' at the end of the rod 48B. The door cannot be opened without a key from the outside.

At the time of the locking (locking) operation, the locking lever 61 is turned on both the inside and the outside of the door so that the clamp 63 blocks the movement of the second swing body 47B to the front.

When releasing (unlocking) operation, simply pull the first touch member 40A on the indoor side first.

As the first spring 41A is contracted, the pull table 45A is pulled, and the first swing body 47A (see FIG. 6B) fastened to the coupling sleeve 45a 'is

 The connecting member 43A and the separating member 43a ', which are guide members 43A, which are coupled to the lower mounting protrusion 42C of the disk 42A via the fixed shaft 43s, and

Since it is coupled to the pinholes 47b and 47c through the displacement shaft 43s',

To move forward steadily,

As shown in FIGS. 6C and 6D, the upper unlocking protrusion 47d of the first swinging body 47A of the first intermediate lever 64 built up in the disk-side first shaft hole 46a of the accumulating protrusion 46A is formed. Lift the first end 64a

Since the second end 64b of the first intermediate lever 64 presses the first end 66a of the second intermediate lever 66 built in the disk-side second shaft hole 46b of the storage protrusion 46A, The second end 66b is raised

Finally lifting the lower end of the locking end (63a) of the clamp 63

Since the locked state is released when the door is closed after the door is opened by moving the first touch member 40A from the inside, the door can be opened by pushing the second touch member 40B from the outside without a key.

The restraint end 63b of the clamp 63 is in contact with the two stoppers 46b provided in the second disk 42B according to the locking and unlocking state of the clamp, and the turning angle is limited.

A torsion coil spring is provided in the axle projection 46B of the clamp 63, and the lower end portion of the torsion coil spring is constrained by the spring installation projection 46b 'so that the locking and unlocking operation of the clamp 63 is prevented. Plays a stationary role. This configuration is like a function of a known spring to exert elasticity in the form of fixing the opening and closing state of the slide phone of the mobile phone, so the description and drawings of the specific structure will be omitted.

Next, as can be seen in FIGS. 6B and 6C and 6F to 6H, the release (unlocking) operation on the outdoor side is performed through a key.

Insert the right key into the keyhole of the key bundle (65) and turn,

As the driving rod 65A rotates, the interlocking rod 65B coupled through the bevel gears 65a and 65b is rotated.

The release end 65b 'of the release member 65B' coupled to the fastening hole 65h (see FIG. 6E [B]) formed at the end of the interlocking rod 65B is the locking end 63a of the clamp 63. Since the lower surface is raised, it is possible to open the door by pushing the second touch member.

That is, when the second touch member 40B is pushed from the outside

The second swing body 47B (see Fig. 6E [B]) fastened to the coupling sleeve 45b 'of the pusher 45B is

The connecting member 43B and the separating member 43b ', which are guide members 43B, which are coupled to the lower mounting protrusion 42C of the disk 42B via the fixed shaft 43s, and (see FIG. 6A);

Since it is coupled to the pinholes 47b and 47c through the displacement shaft 43s' (see Fig. 6C),

As the second spring 41B is contracted, the pusher 45B is stably advanced,

Pressing the acting portion (31B) of the swing member 31 is described above, the ratchet bolt swinging, recessed, the receiving operation is made possible to open the door.

On the other hand, the lever 61 and the interlocking rod 65B are respectively provided with return springs 61s and 65s,

The return spring 61s is such that the pressing projection 61a of the lever 61 always stays in a state of not pressing the locking end 63a of the clamp 63,

The return spring 65s has a lock in a state in which the release end 65b 'of the release member 65B' does not contact the lock end 63a of the catch 63, that is, prevents the forward of the swing body 47B. In the pivoting lowering state of the lock end 63a of 63, the release end 65b 'is kept in contact with the lock end 63a.

In the above description, although the conventionally known technology related to the door opening and closing device is omitted, those skilled in the art can easily infer, infer, and reproduce the same.

In addition, in the above description of the present invention, the door opening and closing device having a specific shape and structure has been described with reference to the accompanying drawings. However, the present invention can be variously modified, changed and replaced by those skilled in the art. Should be construed as falling within the protection scope of the present invention.

For example, the first and second touch members 40A and 40B are operated by pushing and pulling, respectively, in order to implement a technology in accordance with the reality that a door installed in a room is normally opened only in one direction (mainly indoor side). For the purpose of explanation, the concept of the present invention should be interpreted as being applicable to the case of a door that is open only to the outdoor side or a door that is open to both sides.
