Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides a locking plate pivotally attached to the back of a case, which is rotated to an unlocked position or a locked position by an actuating protrusion provided on a handle, and locks the door. This invention relates to a flat handle device in which the handle is pushed into a case when not in use after being closed and locked.

[Prior Art] As disclosed in Japanese Utility Model Publication No. 55-22127, in a conventional flat handle device, a handle housed in a case so as to be freely retractable is pivoted to the side wall of the case with a left-right axis, and a locking plate is attached to the handle. is pivoted to the back of the case with a pivot in the front-rear direction, and a passive hole is provided in the locking plate to which the operating protrusion of the handle engages, and when the handle is pulled out, one side of the operating protrusion engages one side of the passive hole Press the hole edge to rotate the lock plate to the unlocked position, and when the handle is pushed in, push the hole edge on the other side of the passive hole with the side opposite the operating protrusion to rotate the lock plate to the locked position. The door is unlocked and locked by a fixed frame such as the box body using a lock plate.

The passive hole of the locking plate is formed to be sufficiently larger than the cross-sectional dimension of the actuating protrusion, so that when the handle protrudes from the case to a position where it can be pulled out by the bias of the spring,
The operating protrusion is configured to freely rotate within the driven hole and collide with the edge of the driven hole.

Generally, the actuating protrusion is die-cast molded integrally with the handle body from zinc-aluminum alloy, while the locking plate is press-molded from a steel plate.
When the handle is used repeatedly over a long period of time and the side of the actuating protrusion repeatedly collides with the edge of the passive hole, the edge of the passive hole of the relatively rigid locking plate is activated. It will bite into the side part of the protrusion.

In this way, if the edge of the passive hole and the side surface of the actuating protrusion become too stuck, the handle will not rotate, and if you try to force the handle to rotate, the actuating protrusion may become distorted or break. The handle became unusable.

[Problems to be Solved by the Invention] Therefore, an object of the present invention is to prevent the hole edge of the passive hole from biting into the side surface of the actuating protrusion and to prevent the handle from becoming unrotatable, so that the handle always operates smoothly. An object of the present invention is to provide a flat handle device.

[Means for Solving the Problems] Hereinafter, it will be explained in detail using the reference numerals in the attached drawings. The base end of the handle 3 is pivoted to the side walls 6, 7 of the case 5 by a pivot 2 in the direction, and the locking plate 15 is pivoted to the back of the case 5 by a pivot 17 in the front and back direction. Passive hole 16 with protrusion 1 provided in lock plate 15
When the handle 3 is moved in and out of the case 5, the edge of the passive hole 16 is brought into contact with the side surface 1 of the actuating protrusion 1.
In the planar handle device that rotates the locking plate 15 to the unlocked position or the locked position by pressing with the handles a and 1b, the front end of the actuating protrusion 1 is attached to the base end of the handle 3 so as to be pivotable in the left and right directions. Pivotally mounted, operating protrusion 1
A stop portion 14a that contacts one side surface 1a and a pressing portion 4 that contacts the opposite side surface 1b of the actuating protrusion 1 are provided on the back surface of the base end of the handle 3, and the pressing portion 4 and the actuating protrusion 1 A clearance g is provided between the side surface 1b and the side surface 1b.
The play distance g is set so that the handle 3 rotates independently until it protrudes from the case 5 to a position where it can be pulled out under the bias of the spring 8.

[Function] As shown in FIGS. 1 to 5, when the handle 3 is completely recessed into the case 5 and the locking plate 15 is in the locked position, the side surface 1a of the actuating protrusion 1 is in the stop portion 15a. while in contact with the side surface 1 of the actuating protrusion 1
b is in contact with or very close to the upper hole edge of the passive hole 16.

Here, when the handle 3 is activated and rotated around the pivot 2 by the bias of the spring 8, it protrudes from the case 5.
As shown in FIG. 6, the pressing portion 4 comes into contact with the side surface 1b of the actuating protrusion 1. During this time, the actuating protrusion 1 remains stationary, and the handle 3 independently rotates freely with respect to the actuating protrusion 1 by an angle defined by the play interval 〓g.

Hook your finger on the tip 3a of the handle 3 that has protruded to the pullout position in this way, and then
When the handle 3 is further pulled out from the case 5 and rotated, the pressing portion 4 of the handle 3 presses the side surface 1b of the actuating protrusion 1, so that the handle 3 and the actuating protrusion 1 rotate integrally. During this drawing rotation, the sliding contact point of the side surface 1a of the operating protrusion 1 with the hole edge of the driven hole 16 is sequentially moved from the middle portion to the rear end portion.

Locking plate 15 pressed against the side surface 1a of the actuation protrusion 1
As shown in FIG. 8, it rotates counterclockwise around the front-rear pivot shaft 17, and the tip portion is released from the receiving portion on the fixed frame side. When the locking plate 15 has completely reached the unlocked position, the operating protrusion 1 is engaged with the lower end hole edge of the driven hole 16.

When the door is closed and the handle 3 is pushed into the case, the stop part 14a provided on the handle 3 pushes the side surface 1a of the actuating protrusion 1, and the side surface 1b of the actuating protrusion 1 presses against the hole edge of the passive hole 16. To press the lock plate 1
5 is rotated to the locked position.

[Embodiment] In the illustrated embodiment, the protrusion biasing spring 8 of the handle 3 is composed of a torsion coil spring whose coil portion is fitted to the left-right pivot shaft 2, and one straight portion is attached to the rear surface of the handle 3. The other straight portion is in contact with the back wall 9 of the case 5. Push button 10 for starting operation stored in the case below the handle
is urged to slide upward by a compression coil spring 11. When the handle 3 is pushed into the case 5, the locking protrusion 12 at the upper end of the push button 10 engages with the receiving part 13 at the tip of the handle 3, so that the handle 3 is restrained and held in the retracted position.

The base end of the handle 3 is provided with a rectangular recess 14 that is open to the back side, and the front end of the round bar-shaped operating protrusion 1 is inserted into the recess 14 so as to be swingable within a vertical plane. The left-right pivot shaft 2 that pivots the handle 3 to the case 5 is also used as a pivot shaft that pivots the actuation protrusion 1 to the handle 3.

The pressing portion 4 is formed by the upper wall surface of the recess 14, and the stop portion 14a is formed by the lower wall surface of the recess 14. An elliptical driven hole 16 is diagonally provided in the center of the lock plate 15, and an insertion hole 1 for a pivot shaft 17 in the front and rear direction is provided on one side of the driven hole 16.
8 is provided, and a guide shaft rod 1 is provided on the other side of the driven hole 16.
Nine insertion holes 20 are provided in an arc shape.

In this embodiment, both the front-rear pivot shaft 17 and the guide shaft rod 19 are constructed with round-head screws, and both are inserted into the insertion hole 1 through the washer 21 and 22 with spacer tubes.
8 and 20. The locking plate 15 is further provided with latching holes 23 and 24 for locking rods.

The back wall 9 of the case 5 has a relief notch 2 for the actuating protrusion 1.
There are two upper and lower screw holes 26, 27 and 2 on both sides of 5.
9 and 30 are provided. When the flat handle device is used for a left-hand opening door, the longitudinal pivot 17 is screwed into the upper screw hole 26, and the guide shaft 19 is screwed into the lower screw hole 30. When the lock plate 15 is turned over and the flat handle device is used for a right-hand door, the front-back axis 1 is inserted into another upper screw hole 29.
7 is screwed in, and the guide shaft rod 19 is screwed into another lower screw hole 27.

Further, a locking plate 28 is provided at the tip end 3a of the handle 3 to engage with a receiving hole 32 in the case side wall 7 to lock the handle 3 to the case 5 when the handle 3 is inserted into the case 5. .

Note that the present invention can be implemented in various ways, and when the side surface of the tip 3a of the handle 3 is provided with a recess 31 or a groove, it becomes easier to grasp with fingers when pulling out the handle 3, and the convenience of operation is improved. do.
The left-right pivot axis that pivots the handle 3 to the case 5 and the left-right pivot axis that pivots the actuating protrusion 1 to the handle 3 can also be configured separately.

If the handle 3 and the operating protrusion 1 are made of a rigid material such as stainless steel, like the locking plate 15, they will be more resistant to wear and tear due to collisions and sliding contact between them. As the spring for biasing the handle, a well-known curved leaf spring that biases both the projecting direction and the retracting direction can also be used.

Further, as shown in FIG. 9, the pressing portion 4 provided on the handle 3 may be formed so that its entire length or entire surface comes into contact with the side surface 1b of the actuating projection 1. As shown in FIG. 10, when the inner surface of the pressing part 4 is molded to follow the side surface of the actuating protrusion 1, the handle 3
Since the pressing force is applied in a distributed manner, the pressing portion 4 and the actuating protrusion 1 can be more accurately protected from local distortion deformation.

[Effect of the invention] As described above, in the device of the present invention, the actuating protrusion 1
is configured separately from the handle 3, and the front end of the actuating protrusion 1 is pivotally attached to the base end of the handle 3 so as to be swingable about a pivot shaft 2 in the left and right direction, and the side surface 1a on one side of the actuating protrusion 1
A stop part 14a that comes into contact with the side surface 1b of the actuating protrusion 1 and a pressing part 4 that comes into contact with the side surface 1b of the pair of actuating protrusions 1 are provided on the back surface of the proximal end of the handle 3.
Since the play distance g is set between the handle 3 and the handle b, the play distance g is set so that the handle 3 rotates independently until the handle 3 protrudes from the case 5 to the position where it can be pulled out under the bias of the spring 8. 3, when the handle 3 independently rotates freely by an angle specified by the play distance g, the operating protrusion 1 is pressed by the pressing part 4.
However, as in the conventional device, the actuating protrusion 1 rotates greatly and the driven hole 16
There is no forceful collision with the edge of the hole. Therefore, even if used repeatedly over a long period of time, the hole edge of the passive hole 16 will not bite into the side surface of the actuating protrusion 1, causing distortion or breakage of the actuating protrusion 1, and the present invention The flat handle device is highly durable.
