Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a flat handle used for opening and closing doors of cabinets and the like.

Prior Art Figure 4 is a rear view showing a conventional example of a flat handle, in which a swing pin at the top of the back side of an arm that swings supported on the front of the main body swings up and down as the arm swings back and forth. A device that utilizes motion to swing a swinging piece that is swingably supported by a pivot pin on the back of the main body, and uses the movement of the swinging piece to open, close, and lock the door. It is.

Problems to be Solved by the Invention In the above conventional example, since the swinging movement of the swinging piece is parallel to the mounting panel surface, the entire mechanism of the flat handle becomes large, and there are restrictions on where it can be used. Also, from a mechanical point of view that the movement of the swing pin is transmitted through the notch hole provided in the swing piece, the state in which the swing pin is at the highest position (the arm is closed and locked) At an intermediate position between the swing pin being at its lowest position (the arm is open, in this case energized by the spring attached to the arm's support shaft), the relationship between the swing pin and the swing piece is free. This may cause backlash or malfunction.

Means for Solving the Problems The flat handle of the present invention has the following configuration as a means for solving the above problems.

(1) An arm having an arm whose upper end is pivotally supported by a spindle in a space on the front of the main body so as to be able to swing back and forth, and whose lower end is equipped with a latch engagement part, which is wrapped around the spindle and has one end attached to the arm. A part of the spring piece locked to the arm is made to protrude, and the protruding part presses the fixed side of the other party to be locked when the arm is in a closed locked state.

(2) The spring strip is symmetrical and is locked to the arm at both left and right ends, with the central portion protruding along the rear projection of the arm.

Function In this invention, since the spring bar itself that is locked to the arm directly presses the fixed side of the mating member to be locked, vibration and shock resistance are achieved without causing play between the transmission mechanism as in the conventional case. Moreover, since the direction in which the arm is tightened is perpendicular to the mounting surface, there is no limitation on the mounting direction.

Embodiment FIGS. 1A to 1E show an example of the implementation of the present invention, in which 1 is a main body, and 2 is an arm, which is installed in a space in the front of the main body so as to be swingable back and forth by a support shaft 3. An engagement portion 2a with the latch 4 is formed at the lower end of the arm,
Further, a protrusion 2b is provided protrudingly from the upper back surface. latch 4
is inserted by removing the spring cover 6 on the back side, and is constantly pressed by the latch spring 5. When the latch 4 is pushed down from the state shown in FIG. 1D in which the latch 4 is engaged with the arm 2, the state shown in FIG. 1G is reached and the arm 2 becomes free. This G
When the arm 4 is pushed backwards from this state, the protrusion 9a of the spring strip 9 first presses the fixed side of the other device to be locked (in some cases, a part of the main body 1 may be pressed first). When pushed down further, the latch 4 is engaged and locked. The spring strip 9 is symmetrical and has both ends locked to the rear protrusion 2b of the arm,
A central protrusion 9a is provided along the rear protrusion 2b of the arm. Reference numeral 8 denotes a mounting bracket with which the flat handle of the present invention is mounted to a mounting panel such as a door using mounting screws 7.

FIG. 2 is a perspective view showing various states in which the flat handle of the present invention is used, and FIG. 3 is a perspective view showing the assembled state.

Effect of invention (1) The device can be made smaller.

(2) Since the fixed side is directly pressed by the spring strip,
It has vibration and shock resistance, ensuring reliable operation at all times.

(3) Since the tightening direction of the arm is perpendicular to the mounting surface, the mounting direction is not limited and can be used in a wide range of applications.

Claims (1)

[Claims for Utility Model Registration] 1. An arm having an arm whose upper end is pivotally supported by a support shaft so as to be swingable back and forth in a space on the front of the main body, and whose lower end is provided with an engaging part with a latch, A flat handle in which a portion of a springing piece that is wrapped around the arm and whose one end is locked to the arm protrudes so that the protruding part presses the fixed side of the locking partner when the arm is in the closed and locked state. 2. The planar handle according to claim 1, wherein the spring strip is symmetrical and is locked to the arm at both left and right ends, with a central portion protruding along a rear protrusion of the arm.
