Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Use The present invention relates to a frame back plate retainer for pressing a back plate of a frame for storing and displaying documents, and more specifically, for example, Protective glass, framing paper, writings, back plate, etc. are stored in the U-shaped holding groove of the frame in order from the front side, and the gap is formed between the holding groove and the back plate. The present invention relates to a frame back plate retainer for fixing documents by inserting a back plate retainer, expanding the gap of the inserted portion and pressing the back plate toward the front side.

(B) Conventional Technology Conventionally, as a back plate retainer for a frame as described above, for example, as disclosed in Japanese Utility Model Publication No. 63-5595, the shape of a main body formed of an elastic material is used. It is formed in a generally arcuate shape in side view, and on its upper part, a concave part that engages with a projecting edge formed along the frame direction is formed at the lower end of the inner surface of the bone frame when fixed, and both end parts of the arch shape Has a structure in which a flat pressing portion on the lower surface bent at a predetermined angle is formed, and the back plate retainer is elastically generated by an arch shape in a gap formed by the holding groove of the frame and the back plate. It is constructed so as to fix and hold the stored documents and pictures through the back plate by inserting them against each other.

(C) Problems to be Solved by the Invention However, in the conventional structure as described above, the following problems occur mainly in the fixing work and the fixing state of writings.

First of all, a recess is formed in the upper part of the arch shape so as to hold the fixed state of the back plate retainer. In order to release the stopped state, it is necessary to apply a large load to the upper part of the back plate retainer, and there is a problem that the removing work is troublesome.

Moreover, since the engagement between the projecting edge and the concave portion is formed only along the longitudinal direction of the bone frame, the back plate retainer is displaced along the longitudinal direction of the bone frame and the fixation becomes unstable. There was a problem.

Secondly, compared to the presser foot body that is formed in an arch shape and has elasticity, the pressing parts at both ends are formed flat through the corners that are bent at a predetermined angle from the arch part, so the presser foot is inserted. At the time of, the frictional resistance between the flat part and the back plate becomes extremely large, and the tip of the flat pressing part floats up,
Only the corner portion, which is a boundary portion between the pressing portion and the arch portion, comes into line contact with the back plate. Therefore, even if the corners that come into line contact are caught or bite into the back plate and the arch part is pressed from above to insert the retainer into the gap, both ends do not open smoothly, and a smooth insertion operation is performed. There was a problem that was hindered.

Further, as described above, even if the arch portion is pressed from above, both ends do not open smoothly, so it is necessary to apply a large load as described above when removing the back plate retainer. There was a problem that the operability was extremely poor.

Furthermore, when the arch portion of the presser foot is pressed from above and deformed, the load applied to the presser foot is uneven, and for example, in the inserted state, even if the part that presses the back plate is a corner portion. , The center of gravity of the load exists on the arch part side rather than the corner part, so if you continue to use it in that state, distortion will occur in the part where a lot of load is applied and the pressing condition will deteriorate, and the presser foot There was a problem that the durability of the was deteriorated.

This invention reliably prevents the presser foot body from shifting in the longitudinal direction and the width direction of the frame bone frame, and improves the operability when attaching / detaching to / from the gap of the presser foot body and the durability of the presser foot body. An object of the present invention is to provide a back plate retainer for a frame that can be designed.

(D) Means for Solving the Problem The present invention is a frame back plate retainer for inserting a document into a space between a frame and a back plate of a frame and expanding and fixing the space. The frame back plate retainer main body is formed of an elastic member into a substantially arched shape, and a plurality of uneven portions are integrally formed on a top surface portion of the arched shape in a longitudinal direction and a width direction, and The back plate retainer for a frame is characterized in that both longitudinal ends of the retainer main body are formed into curved surfaces, and a knob inclined upward is provided on one side in the longitudinal direction of the anti-slip portion. And

(E) Action In the back plate holder for the frame of this invention, when the slanted knob is held by the fingertips and inserted into the back plate holder of the frame, the bidirectional arrangement of the concavo-convex portions formed on the top surface of the holder body is arranged. In addition to determining the insertion position of the presser foot main body with the non-slip part of the structure, the presser foot main body deforms continuously and smoothly due to material elasticity so as to open its both ends according to the load applied in the vertical direction, Apply even load to the body of the presser foot and press the back plate to fix the writings.

(F) Effect of the Invention As described above, according to this invention, the slip preventing portion in which the plurality of uneven portions are arranged in the longitudinal direction and the width direction is integrally formed on the top surface portion of the arch-shaped presser body, and the presser foot is pressed. Since both ends of the tool body in the longitudinal direction are formed in a curved shape, the position of the back plate retainer inserted in the gap is securely fixed without being displaced in the longitudinal direction and the width direction of the frame frame. This makes it possible to reliably prevent the pressing tool from shifting and to make the contact between the back plates at both ends smooth because the frictional resistance is small, so that the center part of the arch part of the back plate pressing tool for frame is When a load is applied to, the corners are uniformly deformed without being caught, and the load applied to the presser is evenly distributed, as in the conventional case.

Therefore, the work of inserting it into a narrow gap can be done by sliding it, and it is very easy.After inserting, both ends of the curved surface are smoothly closed to firmly expand the above-mentioned gap, At the same time, the non-slip portion of the top surface portion prevents the frame bone frame from shifting in the longitudinal direction and the width direction in both directions, so that the fixing position does not shift and a strong fixing state is obtained.

In addition, when removing the back plate retainer, by applying a downward load to the arch-shaped top surface part, the above-mentioned anti-slip part easily separates from the contact surface of the holding groove of the frame and both ends formed into a curved shape. Since the part opens smoothly, there is an effect that the pressing body can be easily removed by a slight pressing.

Furthermore, since the load applied to the entire back plate retainer is also very stable, the load is not concentrated on a part and distortion is not generated as in the conventional case, and the durability of the retainer can be improved. is there.

Furthermore, since the knob that holds the back plate retainer is tilted upward, the fingertips that hold it are not parallel to the back plate but can be tilted, so that there is a narrow gap due to the presence of the back plate. Even if there is, the back plate retainer can be easily photographed with the fingertips, and the work of inserting or removing the back plate retainer can be easily performed, which facilitates the work.

(G) Embodiment An embodiment of the present invention will be described in detail below with reference to the drawings.

The drawing shows that after storing documents such as protective glass and a back plate in a U-shaped holding groove of a frame that forms a frame, the back of the gap is formed by the holding groove and the back plate. FIG. 1 shows a back plate pressing member for a frame that fixes a document by inserting a plate pressing member and expanding the gap between the plate pressing member and the back plate pressing member 1 for a frame in FIG. It is made of synthetic resin and has a substantially arched shape.

The arch shape has a width corresponding to the width of the gap 5 formed by the back plate 4 in the holding groove 3 of the bone frame 2 shown in FIG. 4, and the arch-shaped top surface has a large number of uneven portions. The anti-slip part 6 arranged in the longitudinal direction and the width direction is formed. Further, a knob 7 slightly inclined upward is provided on one side of the anti-slip portion 6 in the longitudinal direction. A locking hole 7a is formed in the knob 7 so that the operator's finger is locked when the knob 7 is photographed so that the operator can easily take the photograph.

Further, as shown in FIG. 3, both longitudinal end portions 8, 8 of the presser body are formed to have a slightly thicker wall, and the thicker wall is formed into a curved surface having a substantially circular cross-section as viewed from the rear surface side to the front surface side. Is forming.

The illustrated embodiment is configured as described above, and the operation will be described below.

In order to use the back plate holder 1 for a frame, as shown in FIG. 4, the protective glass 9 and the frame are arranged in the holding groove 3 of the frame 2 constituting the frame in order from the front side (in the drawing, the lower side). After arranging the paper 10, the drawing 11, and the back plate 4, with the knob 7 of the back plate retainer 1 for the frame facing the inner side of the frame, the slip prevention part 6 and the knob 7 on the top surface are lowered. To the height of the frame back plate retainer 1 and the gap 5 formed by the back plate 4 of the holding groove 3.
To the base end of the knob 7 as shown by the phantom line in FIG. 4 by sliding the frame back plate retainer 1 toward the gap 5 in that state. Release the pressure. Such work is performed substantially uniformly on the four sides of the frame at appropriate intervals, as shown in FIG.

By inserting it into the gap 5, the back plate holder 1 for a frame, which was in a bulky state as shown by an imaginary line in FIG. 5, becomes a bulky state as shown by a solid line, and will be elastically restored in the vertical direction. While holding the force to be applied, the back plate 4 is pressed with the both ends 8, 8 formed on the curved surface opened, and the top surface portion having the anti-slip portion 6 is pressed against the upper surface of the holding groove 3, It is possible to reliably hold the positions of the presser body in the longitudinal direction and the width direction with respect to the bone frame without displacement. By pressing the back plate 4 toward the front side of the frame, that is, the side of the protective glass 9 in the holding groove 3 of the bone frame 2 that does not expand beyond a certain height as shown in FIG. Certain calligraphy 11
Press to fix the writings 11.

To remove the back plate retainer 1 for the frame when replacing the writings 11, a downward pressing force is applied to the upwardly sloping knob 7 that is inward of the bone frame 2 to open both ends 8, 8. By removing the anti-slip part 6 from the holding groove by footing and then pulling it inward, both end parts 8 and 8 formed into a curved surface slide on the upper surface of the back plate 4, and only one end side can be pulled out from the gap 5. If
After that, the elastic backing force causes the back plate holder 1 for the frame to come out of the gap 5 by itself. The above-mentioned operation of pulling the knob 7 can be easily performed because the knob 7 is slightly inclined upward and the locking hole 7a is formed.

As described above, a large number of uneven portions are formed on the top surface of the frame back plate retainer 1 in the longitudinal direction and the width direction to form the anti-slip portion 6, and the back plate 4 at both ends 8, 8 is pressed. Since the portion to be formed is formed into a curved surface, the back plate retainer 1 can be reliably positioned and fixed to prevent the displacement movement, and the contact between the both end portions 8 and 8 with the back plate 4 causes the friction. Since the resistance is small, it is smooth, and when it is pressed and deformed to be low in bulk, the load due to the load is evenly applied to the whole.

Therefore, the work of inserting it into the narrow gap 5 can be performed in a sliding manner, and it is very easy. After the insertion, both end portions 8 and 8 formed into a curved surface smoothly close the legs and firmly expand,
At the same time, the anti-slip portion 6 on the top surface prevents the frame bone frame 2 from shifting in both the longitudinal direction and the width direction, so that the fixed position does not shift, and a strong fixed state can be obtained.

When the back plate holder 1 is removed, a downward load is applied to the arch-shaped top surface, so that the above-described anti-slip portion 6 easily separates from the contact surface of the holding groove 3 of the frame, and is curved. Since the formed both ends 8, 8 open smoothly, there is an effect that the presser body can be easily removed by a slight pressing.

Further, since the load applied to the entire back plate holder 1 is also very stable, the load is not concentrated on a part and distortion is not generated unlike the conventional case, and the durability of the holder can be improved. There is.

In this way, the frame back plate retainer 1 can be attached and detached extremely easily, and the fixed state becomes strong.

The invention is not limited to the structure of the above-described embodiment.

For example, although the non-slip portion 6 is formed in a pear-like shape in the above embodiment, it may be formed in a relatively large unevenness.
