Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a back plate retainer for a frame for storing works such as calligraphy.

[Conventional technology]

As a back plate holder for the frame, a blade called a dragonfly was rotatably supported on the back side of the frame.However, because of inconveniences such as easy disengagement, the applicant heretofore attaches and detaches the frame. A possible leaf spring type back plate holder has been proposed (for this, Japanese Patent Application No. 59-35594 (Japanese Utility Model No.
No. 0-146461), and Japanese Patent Application No. 57-1
See the microfilm of 89072 (No. 59-93269).

When all of these back plate retainers have a narrow groove deeper than the width on the back side of the frame, insert the tip head into it and use the reaction force to press the back plate with the spring force to move the tip head into the groove. In the former case, the leaf spring as the main body part is in a bifurcated form orthogonal to the head, and in the latter case. Then, the prone posture is formed in series with the head.

[Problems to be solved by the device]

According to the conventional back plate holder of the frame as described above, since the use is limited when the back side of the frame has a narrow groove deeper than the width, it cannot be used when it has a wide groove. Since it was held on the frame by the reaction of the force pressing the back plate and kept that state, the hanging state became unstable due to loss of elasticity and loosening of the back plate, and also
In a large picture frame that uses many of them to partially stop the back plate, it takes time to attach and detach,
There was a problem that replacement of works became inefficient.

Also, since the mounting is partial, the back plate may be wavy and deformed due to warpage, which may spread and damage the work.Also, the gap between the frame and the back plate is almost the entire circumference. Since it is visible over the entire area, there are appearance problems, and there is a risk that dust and dirt may enter through the gap and stain the work. Furthermore, since the mounting state is such that the back side of the frame partly protrudes, the back plate retainer may come into contact with the wall and be damaged when the frame is hung.

In view of the above situation, the present invention is capable of stably engaging with a wide concave groove on the back side of the frame, making it easy to install and remove even with a large frame. Since the plate is pressed around the entire circumference, it is possible to prevent inconveniences such as wavy deformation, and also to cover the gap between the frame and the back plate to prevent dust and dirt from entering through the gap. It is an object of the present invention to provide a back plate retainer for a frame which is not only preventable but also good in appearance and improved in safety.

[Means for Solving the Problems]

In order to achieve the above-mentioned object, the present invention provides a wide concave groove on the back surface of the frame, and a frame extending substantially the entire length of the frame in a frame in which a hook is projected on the inner surface of the concave groove. A pair of inner and outer leg pieces that are pushed into the concave groove to be fitted to the continuous long substrate of, and an engaging claw that is hooked to the latch claw is protruded on the inner leg piece, and A back plate retainer having a frame made of an elastic material is formed by projecting a pressing piece of the back plate over the entire length of the long substrate while inclining in the pressing direction at the inner side end of the long substrate.

Further, abutting slopes may be formed at both ends so that the vertical and horizontal back plate retainers abut each other.

[Action]

The back plate retainer of the frame is configured as described above, and when this is attached to the frame, the pair of leg pieces are pressed while being inserted into the groove of the frame. By doing so, elastic deformation of the two leg pieces causes the engaging claws of the leg pieces to be caught by the hooking claws of the recessed groove, and a stable fixed state is obtained in which the engaging claws do not come off unless the removing operation is particularly performed.

If you attach the back plate retainer to the frame in this way, the retainer piece will face the back plate, but since it is protruding at an angle, even when the back plate is retracted, it is elastically held down. be able to.

Further, since the back plate retainer has a length that extends over substantially the entire length of the frame, the back plate retainer is evenly pressed over the entire circumference so that the back plate does not warp.

An engaging claw may be provided on either the inner or outer leg pieces,
In order to hold down the back plate in a stable manner, it is desirable to provide it on the inner leg of the back plate.

When removing the back plate retainer from the frame, pull up the leg piece side without the engaging claws. That is, when the engaging claws are provided on the inner leg pieces, the outer end of the long substrate is caused by the fingernail or a suitable device. Then, the engaging claw is disengaged from the hook claw mainly by largely deforming the outer leg piece having no engaging claw, so that the back plate retainer can be easily removed.

The back plate retainer may have a length close to the length of the frame, but as in the second item, slopes are provided at both ends as in the frame so that the vertical and horizontal back plate retainers abut on the slope. Is desirable.

That is, by doing so, not only the connection with the frame and the back plate pressing are further strengthened, but also the gap between the frame and the back plate is completely invisible, and the frame is as if seen from the front. Therefore, the appearance is very good. Further, on the back side of the frame, the framework of the back plate holder has a uniform surface over the entire circumference, so that even if it comes into contact with the wall surface on which the frame is hung, there is no risk of damaging the wall surface.

The material for the back plate retainer is preferably made of plastic or rubber in order to effectively perform the above-mentioned effects. However, even extruded shape members made of metal such as aluminum can be used because they have elasticity.

〔Example〕

 Next, an embodiment of the present invention will be described with reference to the drawings.

The drawing shows one embodiment, the back plate holder P of the frame is
One is attached to each frame F.

The frame F is provided with the concave groove 1 in the inner half of the width of the back surface,
The inner side wall 2 of the groove 1 constitutes the inner side surface of the frame F. Then, the tip of the inner side wall 2, that is, the groove 1
The hooks 3 are formed on the inner edge of the forehead, and the slope 4 is formed on the outer edge of the forehead.

In addition, the connecting groove 5 is provided in the inner part of the concave groove 1 by a space that expands to the outer side of the forehead, and the protrusion 6 projecting to the outlet of the connecting groove 5 is provided on the inner side wall 2, whereby the connecting groove 5 is formed. It is formed on. An L-shaped connecting plate is inserted into the connecting groove 5, and the vertical and horizontal frames F are connected via the connecting plate.

The back plate retainer P is made of an extruded shape material of semi-hard plastic, and has an inner side leg piece 9 and an outer side leg piece 10 on a long substrate 8 which is slightly wider than the opening width of the concave groove 1 of the frame F. And an engaging claw 11 that hooks on the hook claw 3 of the frame F is formed at the tip of the inner leg piece 9, and the outer leg piece 10 has a projecting dimension larger than that of the inner leg piece 9. It is formed long.

The long substrate 8 is a continuous, integrated substrate having a length substantially over the entire length of the frame F. Then, a cutout 12 having a curved slope is provided on the outer end of the long substrate 8 on the side that contacts the frame F, and a pressing piece 13 is provided on the inner end so as to project over the entire length of the long substrate 8. 13 is inclined toward the holding side of the back plate 14 and formed so as to become thinner as it goes to the tip, and a warp portion 15 is provided at the tip.

Therefore, the gap 20 between the frame F and the back plate 14 is
It is in a state of being blindfolded by the presser piece 13 which continues to.
As described above, the length of the back plate retainer P is
And end faces 16 inclined at 45 ° are formed at both ends.

When attaching the back plate retainer P to the frame F, by pushing both leg pieces 9 and 10 in alignment with the concave groove 1, the engaging claw 11 is hooked on the latch claw 3, and conversely, when detaching,
The engaging claw 11 is removed from the latch claw 3 by hooking the notch 12 with the fingernail and causing the notch 12.

In either case, since the leg pieces 9 and 10 and the pressing piece 13 are elastically deformed, they can be attached and detached with one touch. Moreover, since the opening edge of the concave groove 1 has the slope 4,
Both legs 9 and 10 are less elastically deformed, and one-touch operation is easy.

2 and 3 show how the back plate retainer P is attached. On the back surface of the frame, the frame F and the back plate are attached.
The gap 20 between 14 is covered by the back plate retainer P.

In addition, the retaining piece 3 and the engaging claw 11 are caught by the pressing piece.
The back plate retainer force of 13 is held, and the retainer piece 13 bends to press the back plate 14 elastically.

[Effect of device]

As described above, according to this invention, the following effects are remarkably exhibited.

1) According to the back plate holder of the present invention, since the back plate is pressed all around, it is possible to prevent the wavy deformation due to the warp of the back plate, and the work is not damaged by the deformation. Even in the picture frame, it holds the work firmly, so it is ideal for protecting the work.

2) Further, on the back surface of the frame, the gap between the frame and the back plate is hidden by the back plate retainer, so that the appearance is very good and the design appearance of the frame can be enhanced. In addition, it prevents dust and dirt from entering and also plays a role in controlling humidity and temperature. Especially, from the viewpoint of protecting works, it is ideal for storing expensive works.

3) In addition, when the inclined slopes are formed at both ends so that the vertical and horizontal backing plate presses against each other, the stability of the pressing of the entire backing plate is further improved, and the appearance is further improved. Therefore, there is no risk of damaging the wall surface on which the frame is hung.

4) In addition, when there is a wide groove on the back side of the frame, it can be stably latched, and the inner leg is provided with an engaging claw that can be hooked by the retaining claw of the groove. The stability can be secured regardless of the elasticity of pressing, and even if the back plate loosens, the work can be prevented from falling off. In addition, it can be securely attached only by pressing in the groove, and when removing it, by pulling out the outer leg piece without the hooking claw first, it is possible to remove it continuously by simply removing the claw from one place, It is possible to surely and easily perform the detaching operation, without wastefully operating the pressing piece at another place.
