Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a frame back plate holding structure for holding a back plate to hold an exhibit on a frame, and more particularly to a frame back plate holding structure suitable for a wooden frame.

[0002]

[Prior art]

 In order to hold the back plate with a wooden frame, a plurality of small holding pieces such as oval and oval are used. The presser small piece is pivotally attached at one end to the back of the frame by hitting a small nail so that it can be selected between a press position where the anti-pigment side presses the back plate by rotation and a non-press position where the back plate is not pressed. I have to.

However, since the holding of the holding piece in the holding position is mainly performed by frictional resistance, the holding piece may be rotated unexpectedly by an external force, and the holding state of the exhibit is unstable. Was. In addition, it could not cope with the case where the thickness of the exhibit was thin or thick, and for example, it was generally determined to be a certificate, for example, and its versatility was low.

[0004]

[Problems to be solved and means for solving them]

 Therefore, the main task of this invention is to provide a frame back plate holding structure that can firmly hold down the back plate even in a wooden frame to obtain a firm holding state of the exhibits.

[0005] A means for that purpose is a frame back plate holding structure in which a back plate is fitted from the back side of the frame body and the back plate is pressed against the front side to hold the display object. A pressing member is formed having an insertion groove in the direction, and a pressing member having an insertion piece inserted into the insertion groove. The pressing member extends obliquely toward the front side of the frame and presses the back plate to the front side by material elasticity. It is characterized in that it is a frame back plate holding structure in which a portion is formed.

The insertion groove may be formed by fixing a fixing member to the back surface of the frame material.

An engaging step is formed on a side surface of the insertion groove opposite to the inserting side, and an engaging projection for engaging with the engaging step is formed on a corresponding side surface at a tip end of the inserting piece. A notch for deformation may be formed in an intermediate portion in the width direction of the insertion piece.

[0008]

[Action and effect]

 That is, according to the configuration described above, in order to hold the exhibit, after the exhibit or the back plate is fitted into the frame, the insertion piece of the holding member may be inserted horizontally into the insertion groove. The back plate is pressed against the front side while the holding portion of the holding member is deformed due to material elasticity. For this reason, the back plate can be firmly pressed down compared to the case of using the conventional presser small pieces, and the difference in the thickness of the exhibits can be accommodated, and the versatility is high.

[0009] In the case of the structure as described in claim 2, since the insertion groove can be formed only by fixing the fixing member without processing the frame itself, the manufacturing is easy and the cost can be suppressed. It has the effect that it can be applied to a certain existing frame or a damaged frame of a holding piece.

[0010] In the case of the third aspect, the insertion step of the insertion piece, that is, the pressing of the back plate by the pressing portion, is performed by the mutual engagement between the engagement step of the insertion groove and the engagement projection of the insertion piece. The state can be reliably maintained.

【Example】

 One embodiment of the present invention will be described in detail below with reference to the drawings. FIG. 1 is a perspective view showing the back side of the wooden frame 1, and the exhibit 4 is held in the frame 5 by pressing the back plate 2 against the front side with the pressing member 3.

The frame 5 has a substantially L-shaped cross-section, and has a protruding portion 5a formed on the inner peripheral edge on the front surface side, and has a transparent front plate 6, an exhibit 4, and a back plate inside. And 2 are inserted in order.

The holding member 3 is made of a synthetic resin such as polyacetal, and is formed in a substantially arch shape as a whole. Further, the intermediate portion 8 is formed flat, and a plate-shaped insertion piece 9 extends from the intermediate portion 8 to one side. More specifically, the holding portions 7, 7 extend slightly horizontally from the intermediate portion 8, and then are formed straight down diagonally downward through the curved portion 8, with a thick pressing portion 11 formed at the tip. doing. The holding parts 7, 7 are formed with a recess 7a for reinforcing and improving the design feeling over substantially the entire area except the pressing part 11, and the upper surfaces of the bases of the holding parts 7, 7 are formed on the shoulders by stroking. That is, a large chamfer is made so that a part of the upper surface is substantially flush with the bottom surface of the concave portion 7a to improve the design feeling.

On the upper surface of the intermediate portion 8, irregularities 8a for preventing slip are formed.

The insertion piece has a notch for elastic displacement at an intermediate portion in the width direction, and has engagement projections 9b on both sides of a tip.

When the holding member 3 is attached to the frame 5, the fixing member 13 as shown in FIG. It is fixed to the back of the body 5.

The fixing member 13 has a rectangular shape in a plan view, and has a through hole 13a for screwing a fixing wood screw 14 on both sides as shown in FIG. At the lower side between the through holes 13a, a slack portion 13b for forming the insertion groove 12 is formed between the through hole 13a and the back surface of the frame 5 so as to form a substantially flat gate. On both sides of one side of the squeezed portion 13b, engaging step portions 13c, 13c with which the engaging projections 9b are engaged are formed, so that the inserted state of the insertion piece 9 can be held as shown in FIG. I'm doing it.

Although the insertion groove may be formed directly in the frame 5 without using the fixing member 13, the insertion groove may be formed at an appropriate position according to the size of the frame 5 by using the fixing member 13. There is an advantage that can be formed. In addition, there is an advantage that the holding member can be attached to a frame in which the provided back plate holder is damaged or an aluminum frame.

In the back plate holding structure of the picture frame 1 configured as described above, in order to hold the exhibit 4, the front plate 6, the exhibit 4, and the back plate 2 are fitted into the frame 5 in order. The insertion piece 9 of the holding member 3 may be inserted horizontally into the insertion groove 12 formed by fixing the fixing member 13 as shown in FIG. As shown in FIG. 3, the pressing portion 7 of the pressing member 3 presses the back plate 2 to the front side while deforming due to material elasticity. For this reason, the back plate 2 can be firmly pressed as compared with the case of using the conventional presser small pieces, and, for example, a thin exhibit 4 such as semi-paper to a thick exhibit such as colored paper can be used. Up to 4, it is possible to cope with the difference in the thickness of the exhibit 4 and the versatility is high.

Further, since the insertion groove 12 can be formed only by fixing the fixing member 13 without processing the frame 5 itself, the manufacturing is easy and the cost can be suppressed.

Further, by the mutual engagement between the engaging step 13 c of the fixing member 13 and the engaging projection 9 b of the insertion piece 9, the inserted state of the insertion piece 9, that is, the pressed state of the back plate 2 by the pressing portion 7 can be ensured. So that it does not accidentally come off due to vibration or contact.

The pressing portion 7 is not formed as described above, but is formed as one, for example, as shown in FIG. 4, or formed into an appropriate shape such as a triangular shape or a semicircular shape in plan view. You may do it.

FIG. 5 shows a back plate holding structure formed so as to be fixed to a corner portion. That is, the holding member 3 is formed with two holding portions 7 at an angle of about 90 degrees, and the fixing member 13 forming the insertion groove 12 into which the insertion piece 9 of the holding member 3 is inserted has an L-shape. Has formed.
