Description

REVERSE LATCH TYPE PLANAR HANDLE DEVICE [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a door handle device for opening and closing a door of a housing such as a distribution panel, a control panel, a cubicle, a cabinet, a rack, a vehicle and an outdoor control box. More specifically, Latching type planar handle device capable of improving the directionality and ensuring the locking function of the door so that the reliability of the product and the convenience of use can be achieved.

In general, a handle used for a cabinet or a large locker is provided with a cylindrical body for fixing a handle to a predetermined position of a cabinet door, a handle is projected to the outside of the door at the center of the cylindrical body, The door is locked and released by being inserted into the groove of the door so that a hole is formed at the upper and lower ends of the cabinet on the inside of the handle so that the locking bar inserted into the hole locks and releases with the supporting protrusion of the door Respectively.

However, since the handle provided in the conventional cabinet is provided so as to protrude to the outside of the door, there is a problem in that it is inconvenient for the passage of arms or clothes during the passage, and particularly the safety of hitting the arm on the handle. The locking bar on the inner side of the door was warped or twisted and the locking and unlocking of the locking bar did not work properly, which made the door uncomfortable for opening and closing the door.

To solve these problems, a latch type flat-type handle device for a door has been developed in which the handle is housed in the case for safe and convenient use.

The latch-type flat-type handle device for a door is capable of locking the door with respect to the fixing body by pushing and pushing the latch body accommodated in the case with a spring and engaging the tip end of the latch body with the receiving rod on the side of the fixing body. This locked state is achieved by pulling out and rotating the latch handle from the case and retracting the latch body against the pressing spring with the operating projection of the latch handle.

Such a conventional latch type flat handle device requires a rotational movement of the latch handle to open and close the door.

On the other hand, in the conventional handle device, when the case is fixed to the panel to be locked, the worker grasps the case with one hand to closely contact the case with the door panel to be locked, and then fixes the case using the fastening means. So that the work efficiency is lowered.

In addition, the structure of the conventional latch type flat handle has a problem in that it is difficult to prevent corrosion due to inflow of rainwater and the structure of the latch or the drive of the reverse latch can not be achieved, so that the structure has a complicated structure, .

As described above, the reverse latch type planar handle device of the present invention allows the locking bar to be in the locked state and the released state in accordance with the four-bar linkage interlocked by the latching operation of the latch handle by the reverse latching method, It is installed in a drainage state without a long period of time to prevent a breakdown due to corrosion, thereby providing a safe and convenient latch handle opening and closing operation, thereby enabling economical and safe use.

In addition, the present invention solves the problem that the latch handle is housed in the case and is not exposed to the outside, so that an arm or a clothes is caught on the latch handle, thereby preventing a safety accident and obtaining a beautiful appearance with a simple structure, .

Further, according to the present invention, the latch handle and the four-section link are improved to a simple and new structure so that the displacement can be easily adjusted and can be produced at an inexpensive price, thereby achieving economical use.

Further, since the present invention does not propagate to the four-bar link and the lock device, it has a structure that can be protected from breakage or damage as the whole component life is prolonged.

Sectional view taken along line BB of Fig.

1 to 7, a reverse latch type flat handle device according to the present invention includes a case 10, a latch handle 20, a locking bar 30, a four-bar link 40, 2 guide 50 (52), a lock unit (60) and a plate (70).

The locking bar 30 is installed to be capable of reciprocating in the horizontal direction at the rear side of the case 10 due to the rising motion of the latch handle 20 mounted inside the case 10, 10 and the lock unit 60 is mounted on the latch handle 20 for releasing and grasping the latch handle 20. The latch handle 20 is provided on the rear side of the case 10,

The latch handle 20 is mounted in the space portion 16 of the case 10 so as to be able to move up and down about the rotary shaft 11.

A four-bar link 40 mounted on the first guide 50 and the second guide 52 is connected to the locking bar 30 and the vertical link 82 on the back of the case 10.

The locking bar 30 is mounted such that the opening and closing operation is performed while being freely passed through the access hole 72 formed in the side surface of the plate 70 and guided by the latch.

The first to fourth arms 41, 42, 43, 44 are interlocked by the link movement.

2 to 6, the case 10 is formed in a box shape in which a space portion 16 is formed on the front surface and a flange 18 is formed on the outer surface.

Between the space portion 16 of the case 10 and the latch handle 20, a cylindrical receiving portion 66 for fitting the lock unit 60 is provided.

That is, the accommodating portion 66 is formed in a cylindrical shape having a storage space below the latch handle 20.

When the key is inserted into the key hole 98 of the lock unit 66 and rotated, the rotor rotates, and the lock unit 66 is tilted and unlocked.

On the other hand, the case 10 and the latch handle 20 are provided so as not to protrude from the surface of the door.

When the latch handle 20 rotates in the forward and backward direction in the case 10, the adjusting protrusion 22 moves in the horizontal direction to push the side connector 84 of the four-bar link 40, 30 can smoothly perform the operation of opening and closing the door by the slide movement.

In addition, if the cabin is mounted on the cargo compartment door of the bus, even if rainwater flows in, the service life of the product can be extended without flowing to the space portion 16.
