Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to a hanging fixture for hanging a string that is used by being attached to the forehead bone of a picture frame.

[Prior art]

In most cases, conventional hanging fittings of this kind have a structure in which the base of the hanging fitting is fitted into a connecting fitting insertion groove provided on the rear side of the forehead and fixed by tightening with screws, so it is difficult to install each time. This method requires a screw tightening operation, making it extremely troublesome to attach and detach the hanging fitting, and has disadvantages such as the tip of the screw damaging the forehead bone surface.

[Purpose of invention]

This invention solves the above-mentioned drawbacks and provides a picture frame hanging fixture that can be attached and detached with a single touch operation without screw operations, and that provides a stable attachment condition without damaging the forehead bone surface. The purpose is to

[Structure of the device] In other words, this device connects a hook piece hooked to a protruding edge piece protruding from the forehead and a latching lever having a string hooking portion through an eccentric shaft, and the latching lever is rotated by rotation of the latching lever. The gist is that the projecting edge piece is clamped and clamped by its eccentric action.

〔Example〕

An embodiment of this invention will be described below with reference to the drawings.

First, to explain the picture frame G using the hanging fitting P, the frame 1 has a surface wall 3 projecting from the front end of the side wall 2, and a front protrusion 4 and a rear protrusion 5 on the inner surface of the side wall 2. A connecting fitting insertion groove 6 is formed by
Furthermore, the side wall 2 and the rear protrusion 5 form a deep groove 7 that is open to the rear end surface. And surface wall 3
A plate glass 8 is hung on the plate, and a back plate 9 is held down by a holding metal fitting (not shown) attached to the deep groove 7.
Furthermore, a hanging metal fitting P is attached to the protruding edge piece 10 inside the deep groove 7.
is attached, and a string 11 or the like is hung on this hanging fitting P for use (FIG. 5).

Next, the hanging fitting P has a hooking portion 12a which is bent and formed into a U-shaped cross section and is hooked on the projecting edge piece 10.
A hooking piece 12 having a substantially semicircular shape, a round hole-shaped stringing part 13 for hanging a string at one end, a circular arc surface part 14 on one side of the other end, and an eccentric shaft located at an eccentric position with respect to the circular arc. The latch lever 16 and the hook piece 12 are connected to each other via the eccentric shaft 15.
The two ends are rotatably connected to each other (the first
figure). That is, in the circular arc surface portion 14, the distance l ₁ from the center of the eccentric shaft 15 to the circular arc surface in the lever width direction is set as the minimum, and the distance l ₂ from the center of the eccentric shaft 15 to the circular arc surface in the lever longitudinal direction is set as the maximum, A flat pressing surface portion 17 is formed continuously from this maximum diameter circular arc surface in the lever width direction. In addition, only the other end side of the locking lever 16 is formed to be thicker so as to increase the area of the arcuate surface portion 14 and the pressure contact surface portion 17.

Furthermore, when the latch lever 16 is oriented perpendicularly to the hook portion 12a of the hook piece 12 and the pressure contact surface portion 17 is opposed to it (Fig. 2), the distance m ₁ between the lever 16 and the hook portion 12a is the forehead bone. Thickness of the flange piece 10 of 1
_m2 , and the above hooking part 12
When the lever 16 is parallel to a and the smallest diameter arc surface side is facing (Fig. 3), the lever 16
The distance m ₃ between the tip of the hook portion 12a and the tip of the hook portion 12a is set to be larger than the thickness m ₂ of the projecting edge piece 10.

Next, the direction in which the hanging fitting P is attached to the forehead bone 1 is to attach the hook piece 12 to the rim piece 10 of the forehead bone 1 on the back side of the picture frame G, with the lever 16 being approximately parallel to the forehead bone 1. At this time, the protruding edge piece 10 has a claw part 10a protruding from the deep groove 7 side, and this claw part 10
Hook the hook 12a onto the frame G, and then rotate the lever 16 so as to raise it toward the center of the frame G (in the direction of arrow A in Fig. 4).
Due to the eccentric action, the arcuate surface portion 14 of the lever 16 gradually approaches the projecting edge piece 10, further comes into contact with it, and finally comes into pressure contact with the maximum diameter arcuate surface. When the lever 16 is finally rotated approximately perpendicularly to the forehead bone 1, the pressure contact surface 17 of the lever 16 and the hook 12a of the hook 12 clamp and clamp the edge piece 10, and the lever 16 is stopped. At this time, the hook piece 12 has some elasticity in the vertical direction about the eccentric shaft 15, and is pressed against the protruding edge piece 10 with this elasticity. In this way,
The hanging fitting P is crimped and fixed to the forehead bone 1 (FIG. 4).

From this state, move the lever 16 in the same direction as when installing.
Since the rotation of is restrained by the pressure contact surface portion 17,
If this direction is made to correspond to the mounting position of the hanging fitting P as the lifting direction of the string 11, a stable mounting state can be obtained without the lever 16 being rotated by the gravity of the picture frame G and becoming unfastened. For example, using symmetrical hanging fittings P on the left and right forehead bones 1 of the picture frame G, the levers 16 are moved in the lifting direction of the string 11, that is, in the direction opposite to the gravity of the picture frame G.
By rotating the hanging fitting P, the hanging fitting P is attached, and the string 11 is passed through each of the hanging parts 13, so that the picture frame G can be hung and hung on a wall surface or the like.

In addition, when removing the hanging fitting P, if the lever 16 is rotated in the opposite direction to that when it is attached, the pressure contact between the projecting edge piece 10 and the hanging fitting P is released due to the eccentric action, and the hanging fitting is removed from the forehead bone 1. P is removed.

In this way, the hanging fitting P can be easily attached and detached by one-touch operation of the lever 16.

In addition, in the above embodiment, the claw portion 10a is formed on the protruding edge piece 10 of the forehead bone 1, and the hook portion 12a of the hook piece 12 is
Although the structure is such that the tip is locked, the claw portion 10a
At the very least, the protruding edge piece 10 can be clamped and clamped by the hook part 12a and the lever 16 to be sufficiently crimped and fixed to the forehead bone 1, and the same effect can be achieved.

Further, the string hooking portion 13 of the lever 16 is not limited to a hole-like shape, but may be formed into a hook-like shape on which the string 11 can be hooked.

Furthermore, in the above embodiment, a structure was described in which the hanging fitting P is fixed by pressure to the inner protruding edge piece 10 of the deep groove 7 for attaching the holding fitting formed on the rear end surface of the forehead bone 1. Even if the end face has a dovetail groove for inserting the connecting fitting, the hanging fitting P can be crimped and fixed in the same way by using the inner projecting edge pieces of the projecting edge pieces on both sides that form the dovetail groove. can.

[Effect of idea]

As explained above, the hanging fixture of this invention has a hook piece that catches on a protruding piece protruding from the rear surface of the forehead, a string hook part at one end, and an arcuate surface part on one side of the other end. The latching lever is rotatably connected via an eccentric shaft with respect to the circular arc, and when the latching lever is rotated, the eccentric action causes the lever and the latching piece to clamp the protruding edge piece and attach it to the forehead. Since it is configured to be crimped and fixed, there is no need to tighten screws to install the hanging bracket, and it can be easily installed and removed with just a single lever operation, and it is crimped and fixed to the edge piece face to face. Therefore, a stable attachment condition can be obtained without damaging the forehead bone surface.
