Description

[Detailed Description of the Invention] Industrial Application Field This invention relates to a picture frame hanging fixture that is attached to the frame frame of a metal picture frame.

Prior Art Picture frames are hung with strings, and hanging fittings for hanging the strings are attached. For wooden picture frames, the hanging fittings can generally be attached with screws, but for metal picture frames, connecting grooves into which the L-shaped connecting fittings are inserted are often opened on the back side of the frame. It may be used to attach hanging hardware.

Since the connecting groove of the frame frame has projecting edge pieces facing each other on both edges of the opening, conventional hanging fittings have a string hooking piece protruding from the connecting groove on the base plate that hangs on both of the projecting edge pieces. Then, we provided a screw hole in the board and a string-hanging hole in the string-hanging piece, so that the screw screwed into the screw hole pushed the bottom of the connecting groove, and the reaction force caused the board to come into pressure contact with the protruding edge piece. It was hot. This pressure welding tightens the board to the frame frame and provides a strong attachment of the hanging fittings, but attaching and removing them involves turning screws, so a tool such as a screwdriver is required to turn the screws. Lack of equipment at home,
This was extremely inconvenient if they were prepared but could not be found. In addition, since the work of turning the screws is quite troublesome, there is a drawback that it takes a considerable amount of time to attach and remove the hanging fittings in museums, exhibition halls, etc. that handle a large number of picture frames.

Purpose of the invention This invention solves the drawbacks of the conventional hanging fittings as described above, and aims to provide a hanging fitting that does not use screws and can be attached to the frame with a single touch. It is.

Structure of the invention In other words, the structure of the invention to achieve the above object is that the lever is formed slightly narrower than the width of the opening of the connecting groove of the frame, and a string that also serves as a knob is attached to the base end of the lever that is lowered into the connecting groove. A hanging piece is provided protrudingly; an eccentric shaft is provided at the tip of the lever to hang on both protruding edge pieces of the opening of the connecting groove;
Both ends of this eccentric shaft are configured such that the diameter D in the lever thickness direction is slightly larger and the lever lengthwise diameter d is slightly smaller than the height L of the protruding edge piece in the connection groove. It is something that exists.

Embodiment The drawing shows an embodiment of this invention, and the hanging fitting P has an L-shaped string hooking piece 2 protruding from the base end of a lever 1, which also serves as a knob.

The lever 1 has a distal end that is slightly narrower than the width of the opening 21 of the frame bone F connecting groove 20, and gradually becomes wider toward the proximal end, and the proximal end has a width that is press-fitted into the opening 21. It's summery. An eccentric shaft 3 is formed at the tip of the lever 1, and an opening 21 is formed at the base end, that is, a regulating portion 4 that fits between the two protruding edge pieces 22, 22 of the opening is formed.

The eccentric shaft 3 has opening protruding pieces 2 of the frame bone F at both ends.
2, 22 are provided, and the diameter D of the protrusions 3a, 3a in the thickness direction of the lever 1 is small relative to the height L of the protrusion piece 22 in the connecting groove 20. The diameter d in the longitudinal direction is relatively small (Fig. 1). Further, the regulating portion 4 is formed to have a height that projects from the opening 21 and is thick enough.

The string hooking piece 2, which also serves as a knob, protrudes at right angles from the regulating part 4 at the base end of the lever 1, and has an auxiliary piece 5 protruding from the tip in parallel with the lever 1, and is L-shaped overall. There is a space 6 between the auxiliary piece 5 and the lever 1.
has. In addition, a string hooking hole 7 is formed at the tip of the auxiliary piece 5, and the string hooking hole 7 is located at the same position as the eccentric shaft 3.

When attaching the hanging fitting P to the frame F of the picture frame G, first insert the eccentric shaft 3 into the connecting groove 20 of the frame F through the opening 21 thereof. In this case, both protrusions 3a, 3 of the eccentric shaft 3 are attached to the protrusions 3a, 3 on both protrusions 22, 22 of the opening.
In order to avoid this, as shown in Fig. 2, the frame bone F is tilted diagonally in the longitudinal direction, and after the eccentric shaft 3 enters the connecting groove 20, it is rotated in the direction of the arrow and rotates normally. Pull back (dotted chain line in the same figure).

In this state, as shown in FIG.
Since the height is smaller than the diameter d, the connection with the frame bone F has not yet occurred, and the hanging fitting P is movable, so if the position is incorrect at this stage, it can be Perform accurate positioning.

Next, push down the lever 1 while twisting the string hooking piece 2, and as shown in FIGS.
When it is laid down in the connecting groove 20, both protrusions 3a, 3a have a height of a large diameter D due to the rotation of the eccentric shaft 3, and come into pressure contact with the bottom surface of the connecting groove 20 and the protruding edge pieces 22, 22, and due to the friction. Since it is fixed, installation of the hanging fitting P is completed in this state.

Due to the principle of leverage, in this case, the eccentric shaft 3 presses against the frame frame F with a strong force even with a small force, and the installation state of the hanging fitting P is stabilized even with this pressure contact alone, but when the lever 1 is lowered, the lever 1 and the regulating portion 4 fit into the opening 21 of the frame F, the hanging fitting P is reliably prevented from swinging in the plane direction of the picture frame G.

When removing the hanging fitting P, just perform the operation exactly opposite to the installation operation. That is, while pulling the lever 1 by pinching the string hooking piece 2 (FIG. 3), and tilting the string hooking piece 2 in the longitudinal direction of the frame bone F (FIG. 2),
Lift the eccentric shaft 3 from the connecting groove 20.

The auxiliary piece 5 is not necessarily required to carry out the present invention, since the string hooking piece 2 only needs to be pinched in this way, but it goes without saying that the auxiliary piece 5 makes it easier to pinch the string hooking hole 7. is provided near the eccentric shaft 3 to prevent the load of the picture frame from strongly acting on the eccentric shaft 3.

As for how to hang the picture frame G, instead of using strings, it is also possible to protrude a nail from the wall and hang a hanging bracket onto the nail.

Effects of the invention As explained above, this invention provides an eccentric shaft at the tip of the lever that hangs over both protruding edge pieces of the opening of the connecting groove of the frame bone, and when the lever is lowered, the protrusions at both ends of the eccentric shaft move toward the opening. Since it is configured to press into contact with both projecting edge pieces, it can be attached to the frame with one touch.
Alternatively, it can be removed, which is an extremely simple operation of pinching and twisting the string hook, which greatly increases work efficiency. In addition, since no tools such as a screwdriver are required, it exhibits excellent effects such as being extremely convenient when attaching and detaching the hanging fittings.
