Regarding locking structure.

(Prior Art) Conventionally, as described in, for example, Japanese Utility Model Publication No. 63-5595, a rectangular back plate for removably holding an object to be supported, such as a painting, between a rectangular frame and a removable leaf spring has been used. A picture frame is known that is held by a stopper. In this conventional picture frame, the frame has a U-shaped cross section and a groove is formed in the inner circumference of the frame, and the outer circumference of the back plate is inserted into this groove, and an arched stopper is formed on the inner circumference of the frame. A structure was adopted in which the fixture was press-fitted and the presser parts formed at both ends of the fixture were pressed into contact with the back surface of the back plate.

(Problem to be solved by the invention) However, in the conventional structure described above, even when the stopper is removed, the protruding wall on the back side of the groove in the frame gets in the way, and if it is left as it is, the back plate is not attached to the frame. Therefore, it is necessary to make at least one side of the frame removable from other parts, and to insert and remove the back plate with this side removed, which is a time-consuming problem. It was hot.

The present invention aims to solve these problems by making it possible to easily attach and detach the back plate without disassembling the frame in a picture frame that holds the back plate using a removable leaf spring. The purpose is to be able to securely hold the back plate.

[Structure of the idea]

(Means for Solving the Problems) In order to achieve the above object, the present invention includes a frame body having an inward facing flange on the inner periphery of the front side, and a frame body that is detachably attached to the inner periphery side of the frame body. A back plate that removably holds an object to be supported by the inward flange, and a stopper that is removably attached to the frame and that presses and holds the back plate from the back side, This stopper consists of a main body that is curved in an almost arched shape and has presser parts at both ends that are press-contacted to the back surface of the back plate, and a main body that protrudes laterally from the central edge of the main body and extends from both ends of the main body. The frame integrally includes a substantially U-shaped elastic insertion piece that is bent in the same direction as the main body and is folded back toward the main body, the elastic insertion piece has a concave portion at its base end, and the frame body A locking groove into which the elastic insertion piece of the stopper is removably press-fitted is formed in the inner circumferential portion, and the back plate is formed at the inner peripheral edge on the front side of the locking groove toward the inward flange. and an inner peripheral wall against which the supported object is detachably abutted,
A protrusion is formed on the inner circumferential edge of the rear side of the locking groove, and the recess of the elastic insertion piece is removably locked therein.

(Function) In the picture frame of the present invention, when attaching an object to be supported such as a painting or a photograph, the object to be supported is first placed on the inward facing flange on the front side of the frame through, for example, a plate glass. An object is brought into contact with the inner circumferential wall of the frame, and a back plate is inserted into the inner circumferential side of the inner circumferential wall of the frame to place it on the supported object.

Next, on the back side of the back plate, insert the approximately U-shaped elastic insertion piece of the stopper made of a leaf spring into the locking groove formed on the inner peripheral surface of the frame from its bent side,
The concave portion of the base end of the elastic insertion piece is engaged with the protrusion of the locking groove of the frame. The stopper is reliably locked to the frame by the engagement of these recesses and the protrusions.

In this state, as the elastic insertion piece is compressed, the approximately arcuate main body of the stop located on the inner circumferential side of the locking groove with respect to the frame is also extended, and both ends of this main body are The pressing part is pressed against the back surface of the back plate. That is, the elastic insertion piece protrudes laterally from the central edge of the main body, is bent toward the same side as both ends of the main body, and is folded back toward the main body.
As the elastic insert piece is elastically compressed, the main body will be elastically expanded.

In this way, the back plate is held in a state in which the object to be supported is held between the inward flange and the back plate by the pressure from the back side of the stopper.

In addition, when removing the supported object, first pull out the elastic insertion piece from the locking recessed groove to remove the stopper, and then pull out the back plate etc. from the frame body.

(Embodiment) Hereinafter, the structure of an embodiment of the picture frame of the present invention will be described based on FIGS. 1 to 3.

Reference numeral 11 denotes a frame, and although not shown, the frame 11 is formed into a rectangular frame shape as a whole. A pair of connecting walls 13 and 14 are vertically formed on the inner peripheral surface of the outer peripheral wall 12 of the frame 11 to protrude vertically over the entire circumference, and extend in opposite directions from the tip edges of these connecting walls 13 and 14. Inner peripheral walls 15 and 16 are respectively formed to be vertically bent and extend over the entire circumference. The gap between both the connecting walls 13 and 14 is the frame body 11.
The groove 17 is a locking groove 17 that opens toward the inner circumference. Also, on the back side (on the upper side in Figure 1, the third

Although the inner peripheral surfaces of both the inner peripheral walls 15 and 16 are located on the same plane, the inner peripheral wall 15 on the back side may be located on the outer peripheral side than the inner peripheral wall 16 on the front side.

Further, a front wall 19 having a substantially semicircular cross section is bent over the entire circumference from the front end edge of the outer peripheral wall 12, and the front end edge of the front wall 19 is wider than the inner peripheral walls 15, 16. It has an inward flange 20 that protrudes toward the inner circumference. In addition, a bumper 21 fitted to the tip edge of the inner circumferential wall 16 on the front side is in contact with the back surface of the front wall 19 over the entire circumference.

Further, bent pieces 22 and 23 are formed by bending the outer circumferential wall 12 and the inner circumferential wall 15 in directions facing each other from their rear end edges, respectively, and the gap between these bent pieces 22 and 23 becomes a groove 24. ing.

Reference numeral 26 denotes a rectangular flat back plate, and the outer circumferential shape of this back plate 26 is slightly smaller than the inner circumferential shape of the inner circumferential walls 15 and 16. Further, reference numeral 27 denotes a rectangular flat transparent plate glass, and the outer circumferential shape of this plate glass 27 is approximately the same as the outer circumferential shape of the back plate 26.
