BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a frame hanging strap fitting that is fixed to the back surface of a frame and serves to hold a hanging strap that suspends the frame.

[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, a hanging string for hanging them is indispensable. The cord is held by passing it through the cord hooking holes of the hanging cord fittings fixed to the left and right sides of the frame back and tying them together.

By the way, in recent years, a frame in which the entire frame is made of a die member made of aluminum has been preferred, and has become popular. In order to assemble the aluminum frame, it is common to apply L-shaped corners to the four corners and screw them together. To hold the L-shaped corners, as shown in FIG. Generally, a mounting groove 12 is provided on the upper side of the concave groove, the mounting groove 12 having projecting edges 11 and 11 facing inward.

In such a frame of an aluminum frame, the hanging metal fitting is fixed to the mounting groove 12 with a bolt or a tapping screw.
It is common to screw it while making a thread groove on 11, 11.

[0005]

However, since this screw-fastened type requires tools such as a screwdriver to attach / detach, it cannot be easily attached / detached, and it is easy to change the vertical and horizontal positions of the frame. It cannot be done. Also, in the case where the tapping screw is directly set on the frame, it requires a lot of knack to attach it, and if the attachment and detachment is repeated several times, the screw thread will be broken and the screw will be inconvenient. It will be enough and cause a fall accident during the exhibition.

Disliked these drawbacks, in recent years,
There is also a structure that can be attached and detached without using a tool by utilizing the elastic force of the spring, but the elastic force of the spring alone is not sufficient to support a heavy frame, so that it is light in weight. It has a drawback that it can easily be displaced if an excessive force is applied for some reason.

The present invention does not require tools for attachment and detachment, and can be easily performed with only fingers, and the attachment state is strong and sufficient supporting force can be obtained, and even if repeated attachment and detachment operations are performed, damage due to wear or the like occurs. The purpose of the present invention is to obtain a hanging strap metal fitting for a frame that does not cause a decrease in supporting force.

[0008]

DISCLOSURE OF THE INVENTION A frame hanging strap metal fitting according to the present invention includes a pair of plate-like body front end portions which face each other at an inner surface of a plate-like interrupting lever located in the middle, and at least one point. Providing each of the above-mentioned intermediate portions with a protruding portion protruding outward,
One plate-like body is provided with a string-engaging portion having a string-engaging hole, and the plate-like interrupt lever and both plate-like bodies are pivotally attached at the rear ends of both plate-like bodies. It is an attempt to achieve the purpose.

Further, the effect of the invention can be further enhanced by providing the projecting portions projecting further outward than the projecting portions under the pair of plate-like members, respectively.

[0010]

In the use of the frame hanging strap fitting of the present invention, first, both plate-like members are made parallel to each other, and the plate-like interrupting lever is raised to a position forming an angle of approximately 90 degrees with both plate-like members. Since both plate-like bodies can be compressed inward by the thickness of the plate-like interrupt lever, as shown in FIG. 3, the mounting groove provided on the back surface of the frame frame while maintaining this compressed state with fingers.
Insert both plate-like parts into 12 from above.

Then, when the triggered plate-like interrupting lever is put back in between both plate-like members, both plate-like members expand by the thickness of the plate-like interrupting lever, and both plate-like members are opened. The respective projections provided at the front end and the intermediate portion start to come into contact with the projecting edges 11, 11 of the mounting groove 12, and finally come into pressure contact. Since this mounting groove is usually made of aluminum, if the material of the hanging strap metal is made harder than that, due to the difference in strength between the two, each protruding part bites slightly into the projecting edges 11, 11. It is pressed in the state. This pressure contact state is continued while the plate-like interrupting lever is retracted between the plate-like members, so that the entire hanging strap fitting is strongly fixed to the mounting groove on the rear surface of the frame.

In this way, after the hanging strap metal fittings are fixed to the left and right mounting grooves on the rear surface of the frame, the strap 13 is inserted into the strap hook hole of the strap hook portion as shown in FIG.
The picture frame can be hung and displayed.

Therefore, when suspending this, a hanging cord is used.
Usually, the center of 13 is hooked on a hook provided on the wall surface, and in such a hanging state, the hanging strap metal is subjected to a pulling force directed obliquely upward as shown by an arrow A in FIG. . This pulling force is mainly applied to the two points B and C shown in FIG. 4, but since this load is received evenly on the left and right, the force applied on the left and right of the hanging strap metal fitting may be uneven. Absent. Therefore, the hanging strap metal fitting is not biased in one direction even if it receives a load due to hanging, and is stably held at the central position, and its supporting force is not likely to be lowered due to deviation, so that the frame can always be reliably held by hanging. It is a thing.

When it is desired to remove the hanging strap fitting in the attached state, if the plate-like interrupt lever is raised from between the plate-like bodies, a clearance can be created between the plate-like bodies, so that the plate-like bodies are held and compressed. Release the contact between the protruding part of the plate and the mounting groove protruding edge,
Just pull it up.

It should be noted that if a projecting portion that projects further outward than the projecting portion is provided below both plate-shaped members, the mounting groove 12
When it is attached to the frame, the overhanging portion sunk into the lower side of the projecting edges 11 and 11 as shown in FIG. 4, so that the supporting force of the frame can be further increased by the locking force at this portion. Even if the pressure contact force of the projecting portion is lowered for some reason and the hanging strap metal fitting is displaced, the projecting portion is locked to the projecting edges 11 and 11, so that the frame can be prevented from falling.
