2 is a perspective view showing a configuration of a rotary shaft of a first door and a second door and a hinge portion, and FIG. 3 is a perspective view of a hand- FIG. 4 is a plan view for explaining a rotation operation of the hand-held prevention door. FIG.

Referring to FIG. 1, a hand-held security door 100 according to an embodiment of the present invention includes a first door 110 and a second door 120, And a hinge portion 130 interconnecting the first and second hinge portions 120.

As shown in FIG. 1, the first door 110 is connected to at least one of the upper and lower rotating shafts 111-1 and 111-2 so as to rotate forward or backward about the rotating shaft.

In an embodiment, the first door 110 has the shape of a rectangular parallelepiped, and the upper surface of the rectangular parallelepiped is connected to the door frame 200 by a rotation axis so that the door can be opened and closed. The first door 110 rotates forward or backward around the rotary shafts 111-1 and 111-2 while drawing a circular trajectory. The rotary shafts 111-1 and 111-2 are fixed to the door frame 200 and inserted into the grooves of the first door 110 to rotate the first door 110, And may be inserted into the groove of the door frame 200 and rotate about the groove together with the first door 110. [

At this time, the rotary shaft may include a structure having a restoring force such that the first door 110 is closed, that is, the horizontal state is maintained. For example, when the first door 110 rotates around the rotation shafts 111-1 and 111-2, an elastic body (not shown) such as a spring is coupled to the inner surface of the first door 110 . When the first door 110 is rotated in one direction, the elastic body has an elastic energy corresponding to the degree of shrinkage. When the applied force is extinguished, a restoring force corresponding to the elastic energy acts, (110) is forced to return to its original position. When the elastic body is restored, elastic energy becomes zero, so that the first door 110 returns to its original position.

2 and 3, when the first door 110 rotates about the rotation axis 111-1, an elastic body 112 such as a spring is attached to the inner side surface of the first door 110 Can be combined. The first door 110 is provided with a support member 113 capable of supporting one side of the elastic body 112. When the first door 110 is rotated in one direction and the first door 110 including the groove is rotated about the rotary shaft 111-1, the protrusion 115 of the rotary body rotates the elastic body 112 The support member 113 supports one side surface of the elastic body 112, and the elastic body 112 is contracted. The first door 110 has an elastic energy corresponding to the degree of shrinkage. When the applied force is extinguished, a restoring force corresponding to the elastic energy acts to return the first door 110 to its original position. As the elastic body 112 is restored, the first door 110 is returned to its original position, so that the first door 110 is automatically closed.

It should be appreciated, however, that such a configuration and operation is merely an embodiment of the present invention, and that various technical means for returning the first door 110 to its original position, i.e., the equilibrium state, Will be apparent to those skilled in the art.

The first door 110 may include characteristics of a general door. In one embodiment, the first door 110 includes a handle 116 and a locking means 117 as shown in FIG. The first door 110 may be made of various materials. For example, wood, glass, plastic, and various other materials are available, and these materials can be used together. In addition, it can have various forms for taking advantage of the aesthetic characteristics.

Also, the first door 110 is connected to the second door 120 via a hinge (see 130 in FIGS. 2 and 3), as described below. The first door 110 or the second door 120 has to rotate relative to the rotation axis of the hinge 130 and the first door 110 and the second door 120 have a clearance in an equilibrium state The surface of the first door 110 in the direction in which the first door 110 is connected to the hinge 130 is formed as a curved surface, as shown in FIGS.

Next, the hinge part 130 of the first door 110 will be described with reference to the drawings. As described above, the hinge 130 connects the one side of the first door 110 to the second door 120.

In an embodiment of the present invention, the hinge 130 may be fixed to one side of the first door 110 and protrude from the first door 110, as shown in FIGS. The protruded portion may be rotated about the rotation axis 131 on the principle similar to the first door 110 described above by forming the rotation shaft 131 in the vertical direction and inserting the same into the groove of the second door 120. The second door 120 rotates forward or backward around the rotary shaft 131 while drawing a circular trajectory.

The rotation shaft 131 is fixed to the hinge 130 and inserted into the groove of the second door 120 to rotate the second door 120. [ Alternatively, the rotary shaft 131 may be fixed to the second door 120 and inserted into the groove of the hinge 130. Although not described herein, conventional techniques for rotating the second door 120 about the rotation axis can be considered.

The rotary shaft 131 may have a restoring force such that the second door 120 maintains a horizontal state with respect to the first door 110. That is, the first door 110 may include a structure similar to a structure having a restoring force that is horizontal with the door frame 200. For example, when the second door 120 is rotated about the rotation axis 131, an elastic body (not shown) such as a spring may be coupled to the inner side surface of the second door 120. And a support member (not shown) is provided on the inner surface of the groove of the second door 120 to support one side of the elastic body. When the second door 120 is rotated in the one direction and rotates about the rotation axis 131, the projecting portion of the rotating body applies a force to the other side surface of the elastic body, and at the same time, the support member supports one side surface of the elastic body, Lt; / RTI > The second door 120 has an elastic energy corresponding to the degree of retraction, and when the applied force is extinguished, a restoring force corresponding to the elastic energy acts to return the second door 120 to its original position . As the elastic body is restored, the second door 120 is returned to its original position, so that the second door 120 is automatically closed.

As shown in FIG. 4, the second door 120 rotates about the hinge 130 by including the above-described structure. When the torque causing the rotation by the restoring force disappears, it returns to its original position and becomes horizontal with the first door 110.

The second door 120 and the first door 110 are connected to each other through the hinge 130 and the force is applied to the second door 120. In this case, The second door 120 rotates forward or backward relative to the first door 110 about the rotation axis of the hinge 130 according to the direction of the hinge 130, Type technical means. It also includes the case where the second door 120 is moved to its original position by using the force of the magnetic field (electromagnetic force) as well as the potential energy of the elastic body.

Like the first door 110, the second door 120 may also include characteristics of a general door. For example, the second door 120 includes a handle (not shown), locking means (not shown). The second door 120 may be made of various materials. For example, wood, glass, plastic, and various other materials are available, and these materials can be used together. In addition, it can have various forms for taking advantage of the aesthetic characteristics.

Hereinafter, the locking function of the hand-held security door 100 according to the present invention will be described.

Referring again to FIG. 1, the first door 110 described above includes a first locking rod 118-1 and a lever 117 for moving the first locking rod 181-1.

The first locking bar 118-1 may be used to lock the second door 120 to the second door 120 by completely closing the second door 120 by fixing the second door 120 to the first door 110 And the second door 120 is not opened. 1, the first locking rod 118-1 is located inside the first door 110 and protrudes to the outside of the first door 110 according to an operation of a lever 117 to be described later, The door 120 can be moved in a state of being inserted into the inside of the door 120.

When the first locking rod 118-1 protrudes out of the first door 110, it moves in a direction in which the second door 120 is positioned. Then, the first locking rod 118-1 is inserted into the receiving groove 121 of the second door 120. A part of the first locking rod 118-1 is still positioned in the first door 110 and the other part is inserted into the receiving groove 121 of the second door 120 so that the first locking rod 118-1 And is positioned over the first door 110 and the second door 120. The second door 120 is not opened and the second door 120 is fixed to the first door 110 and moves together with the first door 110 when a force is applied to the second door 120. [

The first locking rod 118-1 can be made of various materials. For example, wood, glass, plastic, and various other materials are available, and these materials can be used together. The first locking rod 118-1 should have sufficient strength to be able to firmly connect the first door 110 and the second door 120 without being deformed by the force applied to the second door 120. [

When the first locking rod 118-1 is inserted into the receiving groove 121 of the second door 120 and the first locking rod 118-1 is moved to the second door 120 The second door 120 is connected only through the first door 110 and the hinge part 130, so that the second door 120 is opened when an external force is applied.

The lever 117 is a structure for moving the first locking rod 118-1. The lever 117 includes a first end (not shown) formed through the front surface of the first door 110 and inserted into the first door 110. The first end is a configuration for moving the first locking rod 118-1. The operating portion 117-1 protruded to the outside of the first door 110 is a structure for the user to operate the lever.

When the user rotates the lever 117 in a predetermined direction (for example, a clockwise direction) when the operation portion 117-1 of the lever is configured in the form of a rotary dial, the first end is connected to the first lock rod 118 -1 in the direction of the second door 120 to move the first locking rod 118-1. Then, when the user rotates the lever 117 in the other direction (for example, counterclockwise), the first end returns to the original position again. The first locking rod 118-1 can be pushed in the direction opposite to the direction of the second door 120 when the first end returns to the original position.

The first locking rod 118-1 is provided with an elastic body (not shown) and can have a restoring force in the direction of the second door 120 or in the opposite direction when a force is applied through the lever 117. [ For example, when the first end of the lever 117 pushes the first locking rod 118-1 in the direction of the second door 120, the first locking rod 118-1 may have elastic energy . And a means for the first locking rod 118-1 to be fixed in a moving position when the first end is located at a predetermined position. When the user turns the first end portion to the original position by operating the lever portion 117-1, the fixing means of the first locking rod 118-1 is released and the elasticity of the first locking rod 118-1 The energy is transformed into kinetic energy, acting as a force to return the first locking rod 118-1 to its original position.

However, in a state where the first locking rod 118-1 is not inserted into the receiving groove 121 of the second door 120, that is, when the second door 120 is opened, 118-1 may be designed so that elastic energy is converted into kinetic energy when the elastic energy is retained and inserted into the receiving groove 121 of the second door 120. [

In addition, the lever 117 is also designed to have a restoring force so that elastic energy is accumulated when the lever 117 is operated in one direction, so that the lever 117 can be designed to return to the original position easily when the lever 117 is operated in the other direction.

The first door 110 may further include a second locking rod 118-2 since it has to be fixed to the door frame 200. At this time, the lever 117 may be designed to fix the first door 110 to the door frame 200.

That is, the lever 117 includes a second end (not shown) located inside the first door 110, and when the user operates the lever 117, the second end is connected to the second lock rod 118-2 The second door 120 is fixed to the door frame 200 by inserting the second door 120 into the receiving groove 210 of the door frame 200.

In one embodiment, when the operating portion 117-1 of the lever is configured in the form of a rotary dial, the user can rotate the lever 117 in a predetermined direction (for example, clockwise) The second rod 118-2 is moved by pushing one end of the rod 118-2 toward the door frame 200 (upward or downward). Then, when the user rotates the lever 117 in the other direction (for example, counterclockwise), the second end returns to the original position again. When the second end returns to the original position, the second end can push the second locking rod 118-2 in the direction opposite to the door frame 200 direction.

The second locking rod 118-2 is provided with an elastic body (not shown) so that when the force is applied through the lever 117, the second locking rod 118-2 can have a restoring force in the direction of the door frame 200 or in the opposite direction. For example, when the second end of the lever 117 pushes the second locking rod 118-2 toward the door frame 200, the second locking rod 118-2 may have elastic energy. And means for securing the second locking bar to a position in which it is moved when the second end is located at a predetermined position. When the user operates the operating portion 117-1 of the lever 117 to turn the second end to the original position, the fixing means of the second locking rod 118-2 is released and the second locking rod 118-2 Is deformed into kinetic energy and acts as a force to return the second locking rod 118-2 to its original position.

However, in a state where the second locking rod 118-2 is not inserted into the receiving groove 210 of the door frame 200, that is, when the first door 110 is opened, the second locking rod 118- 2 may be designed so that the elastic energy is converted into kinetic energy when the elastic energy is retained and inserted into the receiving groove 210 of the door frame 200.

In addition, the lever 117 is also designed to have a restoring force so that elastic energy is accumulated when the lever 117 is operated in one direction, so that the lever 117 can be designed to return to the original position easily when the lever 117 is operated in the other direction.

The lever 117 is fixed to the door frame 200 by fixing the second door 120 to the first door 110 and fixing the first door 110 to the door frame 200 by a single operation, All of the doors 120 can be closed. That is, in the above-described embodiment, when the lever 117 is moved in a predetermined direction, the first locking rod 118-1 is inserted into the receiving groove 121 of the second door 120 to move the second door 120 The second locking rod 118-2 can be inserted into the receiving groove 210 of the door frame 200 to fix the first door 110 to the door frame 200 while the door is fixed to the first door 110 . Conversely, by moving the lever 117 in a predetermined direction, both the first door 110 and the second door 120 can be opened.

Also, although not shown in the drawings, the handgrip prevention door 100 according to the present invention may further include a third locking rod (not shown) for fixing the second door 120 to the door frame 200.
