The present invention relates to a hinge of a partition door, and more particularly, to easily open and close a partition door that can be opened and closed by using a cam shape for inspection or additional wiring of an electric wire that is wired inside a partition. It's about the hinge.

In general, partitions for division of office space in offices can enhance individual privacy and work efficiency, form mutual communication among employees, and maximize space efficiency to provide a more focused and creative office environment. As the departments perform their duties, they are partitioned to partition the space of each department.

Partitions used for this purpose form a facade by combining a plurality of panels, respectively, on the front and rear of the frame connected in series.

In the frame, the vertical panel and the horizontal panel form a rectangular frame, and a plurality of reinforcing members are disposed in the horizontal direction in the middle of the frame to reinforce the vertical panel.

In an office where wiring of electrical / electronic devices is common, wiring of wires by utilizing the internal space of the partitions allows the internal space of the office to be used neatly and efficiently, so that recent partitions have doors that can be easily opened and closed. Many are released.

When the partition provided with the door is used in this way, it is possible to perform tasks such as the case of frequent office relocation or relocation of the office, the inspection of the wiring and the additional wiring.

Korean Utility Model Registration No. 20-0358037 proposes a structure in which a door is provided in a partition, and the door is made of a semi-automatic opening and closing using a hinge.

However, in the case of the hinge structure of the door, there are many components and the structure is complicated, so that product assembly is not good, and there are disadvantages in terms of cost due to the use of a large number of parts, and there is also a disadvantage in operating performance.

Accordingly, the present invention has been devised in view of the above, and the door is opened by implementing a new type of hinge method combining a cam having a different angle radius when opening and closing a partition door and a rod interlocking along the trajectory of the cam. By opening more than the set time, the door can be automatically opened as much as possible. When the door is closed, the door can be automatically closed when the door is closed more than the set angle, so that the door can be opened and closed easily. The number of components can be reduced, so that the structure can be simplified, and the partition door is hinged using a cam shape which is advantageous in terms of product assembly, economical in terms of cost, and excellent operation performance. have.

In order to achieve the above object, a hinge of a partition door using a cam shape provided by the present invention is integrally formed at a hinge portion of a fixing member, and a cam having a shape having a different surface distance (radius) from an axis center for each angle, and the rotating member The guide is installed in the guide and guides the movement of the rod, and can be slidable in the guide while receiving elastic support by the trailing spring, and the radial position is small when the contact with the surface of the cam always leaves the cam nose by the force of the spring. It includes a rod having the characteristic to go to (P1), and when it is opened above the set angle when the door is opened, it can be automatically opened at the maximum angle and maintained at the same time, and can be automatically closed when the door is closed above the set angle. It is characterized by that.

Here, the nose of the cam is formed in a 60 to 75 ° section along the direction of rotation upward from this relative to 0 ° on the vertical line, and the position P1 of the small radius of the cam is 0 0 on the vertical line It is preferable to form in a 120-150 degree section along the direction which rotates upward based on this.

The hinge of the partition door provided by the present invention adopts a method of opening and closing the door semi-automatically by using an interlocking structure of a cam and a rod, thereby providing convenience in terms of opening and closing operation of the door.

In particular, since the number of components constituting the hinge is small, the overall structure of the hinge can be simplified, the assembly of the product can be facilitated, the cost can be reduced, and the opening and closing performance can be improved by the simplified structure. It has an effect.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1A and 1B are perspective views illustrating a coupling state of a partition door hinge using a cam shape according to an embodiment of the present invention, and FIGS. 2A and 2B are partition door hinges using a cam shape according to an embodiment of the present invention. This is a perspective view showing the disassembled state of the.

As shown in Figs. 1A and 1B and 2A and 2B, the hinge of the partition door is automatically opened when the partition door is opened at a set angle or more, for example, about 60 to 75 degrees or more. For example, it can be opened at about 120 to 150 ° and at the same time it can be kept open. Also, when the partition door is closed, it will be automatically closed if it closes more than a set angle, for example, about 60 to 75 °. have.

To this end, the hinge of the partition door is composed of a long rod-shaped fixing member 10 installed on the partition frame side and a long rod-shaped rotating member 11 installed on the partition door side, the fixing member 10 And the rotating member 11 are coupled to each other in a rotatable form by the pin 19, the other side, the binding arm member 21 and the binding member 22 which can be locked and released from each other in an elastic structure is Each is equipped.

Accordingly, since the fixing member 10 and the rotating member 11 can be rotated around the portion where the pin 19 is fastened about the central axis, the entire partition door including the rotating member 11 is opened. It can be closed, and the closed state of the partition door can be maintained by the locking action between the binding male and female members 21 and 22 which the fixing member 10 and the rotating member 11 each have.

The fixing member 10 is a part fixedly installed on a frame of a partition, for example, a vertical frame, and is provided with a plurality of wire hooks 20 arranged at regular intervals along a longitudinal direction on a front surface thereof. A cam 12 is formed which induces automatic opening and closing of the partition door.

The cam 12 has a shape in which the surface distance is different from the axis center for each angle, that is, the radius of the cam 12 is different for each angle. For example, as shown in FIG. 2A, the center of the cam 12 is shown. When the vertical line passing through the axis is defined as 0 °, the nose 16, which is the vertex of the cam, is formed at an interval of 60 to 75 ° along the direction in which the rotation proceeds upward from this point with respect to 0 ° at this time. Positions P1 having two small radii of (12) are respectively formed in a section of 120 ° to 150 ° along the direction of rotation upward on the basis of 0 ° on the vertical line and the reference here.

Accordingly, when the rod 13, which will be described later while moving in line contact along the circumferential surface of the cam 12, proceeds to either the upper side or the lower side with respect to the nose 16 of the cam 12, the radius is automatically small. The door can be opened or closed while being moved to the position P1.

The rotating member 11 is installed on the partition door side and rotates together when the door is opened and closed. The rotating member 11 is configured to include a guide 14, a rod 13, a spring 15, and the like inside the upper end.

The guide 14 is formed in the form of a plate having a cut-out portion in the center of the width, one side is fastened by the pin 19 to the cam 12 side of the fixing member 10 together with the rotating member 11, the other One side is installed in the structure which is fastened and fixed to the inner surface of the rotating member 11 with a screw.

In addition, the guide 14 is formed with a slide rail 17 on both sides of the incision portion to guide the slide groove 18 of the rod 13 fitted therein.

The rod 13 is a means for inducing a substantially automatic opening and closing of the partition door through a linear contact motion with the cam 12, and is formed in a structure slidable back and forth on the guide 14 side, for example, on both side surfaces. It is installed in a structure that can be guided by being inserted into the slide rail 17 in the guide 14 through the slide groove 18, and the rear end thereof is provided in the spring 15 interposed between the guide 14 and the guide 14. It is intended to receive elastic support.

As a result, the rod 13 has a characteristic of always going forward by the force of the spring 15, so that the rod 16 is always out of the nose 16 of the cam 12 in line contact with the surface of the cam 12. At the same time the radius of the cam 12 can go to a small position (P1).

As shown in FIG. 3, two hinges 100, each consisting of the fixing member 10 and the rotating member 11, are provided on each of the two edge frames 110 of the partition, respectively, and the hinge 100 is provided. ), The fixing member 10 is fixed to the frame 110 side, and the rotating member 11 is fixed to the partition door 120 side, thereby completing the installation of the hinge 100.

Accordingly, the partition door 120 is automatically opened at the maximum angle when lifted upward by a predetermined angle or more by the interlocking structure between the cam 12 and the rod 13 in the fixing member 10 and the rotating member 11. Can be closed and automatically closed if it is flipped downwards over a certain angle (of course, the final closed state is maintained by the user pressing the door).

Therefore, the operation state of the partition door hinge configured as described above is as follows.

4A to 4C are cross-sectional views illustrating an operating state of a partition door hinge using a cam shape according to an embodiment of the present invention.

As shown in FIG. 4A, the partition door is shown in a closed state, and the fixing member 10 and the rotating member 11 are kept closed by the locking action of the binding female members 21 and 22. Can be.

As shown in FIGS. 4A and 4B, when the partition door is opened for wiring work, inspection work, or the like in the partition, the operator first pulls the lower end of the partition door to bind the binding arm member 21 and the binding water member 22. ) And then lift upwards, the rod 13 in the rotating member 11 follows the surface of the cam 12 from the position P1 where the lower radius of the cam 12 is small. While moving in line contact with each other and closer to the nose 16 portion of the cam 12, the spring 15 is pushed backward while compressing, and when the opening angle of the partition door is about 60 to 75 degrees, that is, the rod ( At a time when the 13 is positioned at the nose 16 of the cam 12, the rod 13 is pushed backward with the spring 15 compressed to the maximum.

Subsequently, when the partition door is lifted upwards, the rod 13 leaves the nose 16 of the cam 12 and at the same time receives the restoring force of the spring 15 and moves forward again. As a result, the rod 13 automatically moves to the position P1 where the upper radius of the cam 12 is small, so that the partition door is opened at the maximum angle (120 to 150 °), so that the opening state can be maintained at this time. do.

In other words, if the partition door is lifted by about 60 to 75 degrees or more, it is automatically opened at the maximum angle thereafter.

In addition, when the partition door is closed after the wiring operation, the rod 13 is released from the nose 16 of the cam 12 and the spring ( Under the restoring force of 15), the rod 13 is moved forward again, and the rod 13 automatically moves to the position P1 where the lower radius of the cam 12 is smaller due to the spring force at this time (actually 0 ° Instead, it automatically moves to a position close to 0 °), and finally, the operator presses the partition door to lock and lock the binding male and female members 21 and 22 to maintain the closed state of the partition door.

As such, by providing the cam integrally at the hinge portion for the rotation between the fixing member and the rotating member, it is possible to reduce the number of parts by eliminating the use of various components such as separate cams, protrusions, rollers, and the like. In addition, by providing only one pin fastening portion for the configuration of the hinge portion, assembly is simple and the number of parts can be reduced.

In addition, since the assembly portion of the fixing member and the rotating member is a hinge portion (pin fastening portion), interference can be minimized when the rotating member is opened and the wiring work is performed.
