Description

{Door attached automatic hinge with damper} [0001] The present invention relates to a door with a gas damper-

The present invention relates to a hinged door with a gas damper mounting type automatic hinge region mounted thereon, in which a hinged cylinder having a rotating cylindrical hinge type cylinder is equipped with a gas damper mounting type automatic hinge region inside a rotary cylinder, To the automatic returning door having a function of closing the door to its original position.

Generally, a door is installed in a building, and unless it is required to have a special shape, it is usually made of a left and right vertical member and an upper and a lower horizontal member, and is made of wood, synthetic resin material, metal material, The assembled door frame is installed at the same time.

In recent years, there have been many cases such as multi-generations, officetels, apartments, etc., so that the demand for doors has been rapidly increased, and the mass production system has been established in accordance with the rapidly increasing demand. As a result, the left and right vertical members, All of them were assembled and supplied in a rectangular shape.

Particularly, among the various types of doors, the hinge mounted on the access door of the hinged type, which is used most frequently, performs only the rotation function of maintaining the smooth rotation of the door.

In addition, in the case of a door closer that applies a rotational force to automatically return the door, an additional structure is generally installed inside or outside the door hinge.

In the case of the conventional door hinge closure, the door is automatically returned using a spring or cylinder mounted on the outside.

In the conventional hinge device, a spring type is widely used. However, the elasticity of the spring is lowered during use, the door is not opened smoothly due to excessive elastic force, or the return force to return to the original position is excessive, And reaches the reverse position.

 There is a need to control the closing speed of a door or door closure after opening the door. For example, when closed by gravity, it is required to close the door at a constant or controlled speed when the door is closed by an external sudden impact.

In the case of the conventional door hinge or door closure, it is difficult to control the door to close quickly due to an external sudden shock or the like. In particular, in the case of the door closer, the length and weight of the hinge are increased At this time, when a separate device is additionally mounted on the outside of the door hinge, problems such as increase in cost and inconvenience in mounting have arisen.

In addition, when the door is closed due to a predetermined return force when the door is returned, if the return force is strongly set, the door is closed too quickly, and the user is injured. On the contrary, There is a problem in that it is not closed.

1 is a schematic view showing a door according to the present invention. In the door, a hinge-type column 11 of a rotary cylinder is attached to the door 10; The hinge-like pillars 11 are attached to the corresponding door frame 20 to form door openings.

The hinged door 10 is seated on the frame 20 corresponding to the hinged cylinder 10 so as to open and close the door. The hinged door 10 is simply opened by a user, But the door opening / closing speed is not restricted so that the door can be shocked when it is closed and an accident that the next user may hit the door may occur. When the door is fully opened, There is a phenomenon in which the door can not be returned or the door can not be closed smoothly even when the door is closed again.

In the present invention, an automatic return hinge (not shown) is formed inside a cylindrical hinge-type cylinder 10 so that the door can be opened or closed gradually in the process of opening or closing the door or can be smoothly returned to its original closed state. (30) is mounted.

FIG. 2 is a schematic view showing an automatic return type hinge region mounted in a completely closed state of a door according to the present invention,

An automatic return type hinge region (30) is fixed to an inner end of the hinge type column (11);

The hinge region 30 is constructed as follows.

First, the gas damper 31 is attached to the inside of the gas cylinder 34 so as to reciprocate. In the initial state, the length of the gas damper 31 is maximized by the gas pressure inside the gas cylinder 34 A constant force is applied to the inside of the gas cylinder 34 and a constant gas pressure is generated in the gas cylinder 34 in the diameter of the gas damper 31. If no external force is applied to the gas damper 31, And is formed in a maximum length which is the initial state again by the gas pressure inside the cylinder 34. [

A rotating cam 32 is attached to the gas damper 31 and a cam 32a having a predetermined trajectory is formed on the circumferential edge of the rotating cam 32. [

A fixed cam 33 is formed corresponding to the rotatable cam 32 and the fixed cam 33 is fixedly mounted so as not to rotate inside the hinged column 11. [

Thus, when the rotatable cam 32 starts to move along a given trajectory of the cam 32a in the setting trajectory, it is moved up and down by sliding along the given cam trajectory of the fixed cam 33. [

The gas damper 31 is moved up and down simultaneously inside the gas cylinder 34 when the cam 32 moves up and down. FIG. 2 shows the gas damper 31, No gas pressure is applied to the inside of the gas cylinder 34 and the trajectory of the rotatable cam 32 reaches the lowest position point of the fixed cam 33 corresponding thereto .

FIG. 3 is a schematic view showing an automatic return type hinge region in which the hinged door according to the present invention is installed in a fully opened state,

When the hinged door 10 starts to be opened, the gas cylinder 34 and the rotatable cam 32 are rotated at the same angle as the opening degree, whereby the rotatable cam 32 at the lowest position point is rotated The gas damper 31 attached to the rotatable cam 32 is moved in the direction of the gas cylinder 34 so that the gas cylinder 34 is moved upward along the cam track of the stationary cam 33 by the cam 32a, As shown in FIG.

When the hinged door 10 is fully opened, the rotatable cam 32 reaches the maximum position corresponding to the fixed cam 33 and reaches the maximum position point. At this time, the gas damper 32 is closed by the gas The inner pressure of the gas cylinder 23 is changed to the maximum pressure while the gas damper 32 is moved to the outside of the gas cylinder 34 by the gas pressure inside the cylinder 34 It has the potential to head in the direction.

Also, the cam (32) is formed at a set angle; Since the normal door 10 is formed so as to be opened or closed by 90 degrees, a smooth circumferential track is repeatedly formed four times from the highest point to the lowest point at the setting angle of 90 degrees. The angle and shape of the inclined surface in the circumferential orbit can be suitably designed by the opening / closing mechanism of the door 10, which is well known in the art and is not related to the features of the present invention. do.

The mechanism for opening and closing the door 10 will be described as follows.

When the door is opened in the closed state, the rotatable cam 32 located at the lowest point starts to move to the highest point along the set cam track, and the gas damper 31 is also moved to the gas cylinder 34, So that the gas pressure is increased,

The gas damper 31 is also subjected to the maximum gas pressure so that a return force to return to the original position is formed. This return force is transmitted to the rotary cam 32, So that the rotatable cam 32 starts to descend again to the lowest point so that the access door is closed; .

The operation of the door 10 is related to the design of the cam 32a of the setting trajectory formed so that the rotatable cam 32 and the fixed cam 33 perform the cam movement with each other.

In another embodiment, when the door 10 is opened and closed in the range of 120 ° or when the door is opened and closed in the range of 180 °, The rotary cams 32 repeatedly form smooth circumferential trajectories three times repeatedly from the highest point to the lowest point at intervals of 120 占 or repeatedly form circumferentially smooth trajectories twice from the highest point to the lowest point at intervals of 180 占 and the corresponding gas damper (31) also enters the gas cylinder (34) to generate a constant gas pressure; .

Since the fixing cap 40 is attached to the end of the door frame 20 for finishing and finishing, the fixed cam 33 of the hinge section 30 is inserted into the fixing cap 40 So that the bearing 50 is attached to the lower end portion of the fixed cam 33 for selectively turning the rotation of the rotary shaft 33; .
