[Detailed description of the device]

[0001]

[Industrial application] The present invention is fixed to the back of the frame,
The present invention relates to a frame hanging metal fitting that suspends a frame on a wall surface.

[0002]

2. Description of the Related Art In a picture frame for holding mainly flat works such as paintings, prints and photographs and hanging them on a wall for display, some means for hanging them is necessary, and generally, The most convenient and widely used means is to tie a string to a string ring fixed to the left and right sides of the back surface of the frame and hook it on a hook fixed to the wall surface.

However, according to this method, it is extremely easy to remove the displayed frame. Therefore, if this frame is used as a frame for decorating a hotel room, it can be easily removed.
Not only the contained works, but also the frames are often stolen.

[0004] Therefore, in order to prevent such a theft, a frame hanging metal fitting for fixing the displayed frame so that it cannot be easily removed has been demanded and various proposals have been made. An example is as shown in FIG. 7, in which a pair of upper metal fittings 21, 21 having a water drop type through hole 20.
And a lower metal fitting 23 having a horizontally long through hole 22 are respectively fixed to appropriate positions on the back surface of the frame F, and the water drop type through hole of the upper metal fitting is hooked on a support shaft 24 having an expanded head fixed to a wall surface, and at the same time, the lower metal fitting. Is set in a direction in which the flat head can pass through the horizontal through-hole, and then passed through the screw 25 having a flat head in which the horizontal through-hole 22 is rotatably screwed to the wall surface. Using a special tool, the flat head is rotated so that the flat head faces the vertical direction, and is fixed so that the flat head does not come out of the horizontally long through hole 22.

[0005]

[Problems to be Solved by the Invention] With this system, the display frame can be fixed so that it cannot be removed from the wall surface without some kind of tool. Bracket 21,2
The support shafts 24, 24 and the screw 25 must be precisely positioned and mounted so as to accurately correspond to the distances a, b, c between the through holes of 1, 23, and even if this position is slightly deviated, the frame is Not only is it impossible to install it, but there is also the drawback that it requires extremely strict measurement and installation work to obtain the horizontal display state of the frame.

The present invention eliminates such drawbacks of conventional products,
When attaching the frame to the display, it does not require a very strict work procedure, it can be easily attached, and the horizontal display state can be easily obtained. It is an object of the present invention to provide a forehead hanging metal fitting that can be easily fixed so as not to be removed from the wall surface and at least eliminate the possibility of theft due to the workmanship.

[0007]

The anti-theft frame hanging metal fitting of the present invention is supported on a support substrate 3 which is attached in parallel to the back surface of a frame through a side wall plate 2 which rises from a foot portion 1 fixed to the back surface of the frame. One end of the inclined elongated hole 4 provided so as to form an angle slightly inclined from the horizontal direction when the substrate is positioned vertically, and a circular hole 5 provided so as to have an inner diameter larger than the width of the inclined elongated hole. Is connected to a guide hole 6 having substantially the same width as the slanted long hole, and a screw shaft 7 projecting so as to close the passage in the middle of the guide hole 6 is screwed into the side wall plate 2 in a metal fitting. The object of the present invention is to achieve the object by adopting a configuration in which a pair of metal fittings 10a, 10b in which the inclined elongated holes have opposite inclination directions are combined.

If the rough surface 8 is provided on the lower surface of the upper edge of the slanted long hole 4, the effect of the invention can be further enhanced. If the inclined long hole 4 and the guide hole 6 are formed in a substantially L-shape at the lower end, and the screw shaft 7 is screwed to the side wall plate parallel to the guide hole 6, the operability is improved. It is effective in improving.

[0009]

In the use of the forehead hanging metal fitting of the present invention, as shown in FIG. 5, first, the foot portion 1 is screwed to the upper left and right rear portions of the frame F to fix the both metal fittings 10a, 10b. Next, measure the distance between the central parts of the slanted long holes 4 and 4 of both fittings,
A pair of support shafts 11 and 11 each having an expanded head 12 having a diameter smaller than the inner diameter of the circular hole 5 and larger than the width W of the slender elongated hole 4 at an interval D substantially equal to the distance are provided at arbitrary positions on the wall surface. Stick to it. This support shaft may be provided by directly screwing a screw having an expanded head on the wall surface K as shown in FIG. 4, and as shown in FIG. 6, a stop shaft having an expanded head is provided on the lower portion. Metal fittings
It can also be provided by fixing 13 to the wall surface with a pin P.

After the installation of the support shaft, the forehead suspension metal fittings 10a,
The screw shafts 7 and 7 of 10b are pivotally retracted to release the passages of the guide holes 6 and 6, and the circular hole 5 of one of the forehead suspension fittings 10a is matched with the expanded head 12 of the corresponding support shaft 11a. After passing through the guide hole 6, it is guided into the slanted long hole 4 through the guide hole 6. Support shaft in this state
If 11a is moved until it reaches near the tip of the slanted elongated hole 4, the circular hole 5 of the other forehead hanging metal fitting 10b comes into a state of matching with the support shaft 11b as shown in FIG. Large head
12 is passed through the circular hole 5 and then drawn into the inclined long hole 4 through the guide hole 6.

When this state is reached, the frame F is pulled back so as to be positioned in the center, so that both the support shafts 11a and 11b are connected to the metal fittings.
The upper edges of the slanted elongated holes 4 and 4 of 10d and 10b are supported, and further the bulging heads 12 and 12 are held in a state that cannot be escaped.

Since the slanted holes 4 and 4 of the pair of frame suspending metal fittings 10a and 10b are provided so that the slanting directions are opposite to each other, one of them can be moved by moving the suspended frame F to the left and right. If it goes up, the other will go down, so that the horizontal display state of the frame can be easily obtained.

Further, in this state, the forehead suspension fitting 10
If the screw shafts 7 and 7 of a and 10b are pivotally advanced and positioned so as to block the passages of the guide holes 6 and 6, no matter whether the frame F is moved to the left or right, the tips of the screw shafts 7 and 7 are moved. It is impossible to remove the suspended state of the frame without using tools, as it will prevent further movement in the department.

As described above, the forehead hanging fitting of the present invention is used. In the construction, the slanted elongated hole 4 is a laterally elongated hole so that the supporting shafts 11a and 11b can be installed in the left and right directions. Even if there is some deviation, it is possible to cope with it, and since it is possible to cope with vertical deviation as described above, it is not necessary to be so strict in its installation work, and it is easy to work. Is possible.

By providing the uneven rough surface 8 on the lower surface of the upper edge of the slanted long hole 4, the support shafts 11a and 11b are supported in a state where they enter the uneven rough surface 8, so that they can be easily displaced right and left. It does not move, and serves to maintain a good display condition in a stable manner.

Further, a circular hole 5 is provided below the outer end of the slanted long hole 4 so that the slanted long hole 4 and the guide hole 5 are substantially L-shaped, and the side wall plate 2 parallel to the guide hole 5 is screwed. If the shaft 7 is screwed, the screw shaft 7 can be operated from the outer side, which is advantageous in improving operability.
