Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a picture frame, and more particularly, to a front openable picture frame that allows a certificate of diploma, calligraphy, and the like to be taken in and out from the front.

[0002]

[Prior art]

 Generally, the amount of money used for storing award certificates includes a frame, a transparent body attached to the inner periphery of the frame, and a back plate that supports the transparent body from the back side. The back plate is held by a back plate retainer called a `` register mark '' that is rotatably provided at the position of .When displaying a certificate of merit etc. using this, it is necessary to remove the back plate A certificate of merit is superimposed on the transparent body, and then the back plate is superimposed on the back side of the certificate, etc., and the certificate is sandwiched between the transparent body and the back plate. The back plate is pressed from the back side at one end of the register mark by rotating the provided holding member called a register mark so that the back plate does not come off.

As described above, the frame generally used in the past has a structure in which a prize and the like are put in and out from the back surface. In this structure, for example, a prize in a state where the frame is hung on a wall or the like. Due to the difficulty of putting in and taking out the frame, the front openable frame has begun to be provided in recent years.

[0006] That is, FIG. 6 is a view for explaining the front openable frame, and FIG. 6 shows a state in which a part of the front openable frame is disassembled. In this frame, a corner frame 21 having an engagement shaft 22, a transparent body, a diploma, and the like, an insertion groove 23 into which a back plate is inserted, and an engagement groove 24 engaged with the engagement shaft 22 are formed in a longitudinal direction. The movable frame 25 is attached to the corner frame 21 by using an elongated movable frame 25 having the following shape so that the engaging shaft 22 of the corner frame 21 is engaged in the engaging groove 24 of the movable frame 25. The movable frame 25 is framed in a rectangular shape, and the movable frame 25 can be freely opened and closed with respect to the corner frame 21.

When displaying a diploma or the like using the frame, first, the movable frame 25 is opened. Then, after arranging the transparent body, the diploma, etc. and the back plate in the framed movable frame 25 so as to be overlapped in order, these end portions are inserted into the insertion grooves 23 of the movable frame 25. Return the movable frame 25 to its original state. Then, it is possible to fix a diploma or the like in the movable frame 25.

[0006] As described above, in the conventional open-ended picture frame, it is possible to put in and take out a diploma from the front side. Therefore, it is possible to put in and take out a diploma with the picture frame hung on a wall or the like. There was an advantage that there is.

[0007] However, in the conventional open-ended front picture frame, the movable frame is simply supported by the corner frame, so that the movable frame is opened by a slight impact or the like. The problem of getting it was considered.

In order to improve this point, there has been provided an improved front openable frame which applies a biasing force to a movable frame using a leaf spring (Japanese Utility Model Laid-Open No. 6-62867).

FIG. 7 is a cross-sectional view for explaining the improved front opening / closing frame. In the improved front opening / closing frame, a fixed frame 31 framed in a polygonal shape and the fixed frame 31 are shown. A movable frame 32 pivotally supported by the open / close mechanism 31 is provided. A leaf spring 33 is interposed between the fixed frame 31 and the movable frame 32 in a bowed manner. 32 is configured to be biased in the opening and closing direction. Therefore, in the improved front openable frame, the movable frame 32 is biased in both the opening and closing directions by the leaf spring 33, so that the movable frame 32 opens and closes even when an impact is applied. Can be prevented.

[0010]

[Problems to be solved by the invention]

 However, in this improved front opening and closing type frame, the use of a leaf spring causes the biasing force to be too strong, and a considerable force must be required to open and close the movable frame. there were.

In addition, when a leaf spring is used, there is a risk that the user may be injured by an end of the leaf spring or the like when attaching the leaf spring, and thus there is a problem that the attachment is dangerous.

Further, in the case of a leaf spring, if it is bent excessively, there is a risk that the limit of elastic deformation is exceeded and the function as a spring is lost.

Therefore, the present invention provides a front panel that does not open the movable frame even when an impact or the like is applied, and that allows easy opening and closing of the movable frame. An object of the present invention is to provide an openable frame.

[0014]

[Means for Solving the Problems]

 The frame of the present invention is a frame having a substantially polygonal shape, a fixed frame including a back plate sandwiching a diploma and the like, and a mounting groove in which the end of the transparent body is mounted, and a ring receiver. A movable frame provided with a ring receiver opposed to the ring receiver, which is rotatably supported on the side so as to be openable and closable; and a movable frame mounted between the ring receivers for urging the movable frame in the opening and closing direction. And an elastic ring that can be deformed in the inner diameter direction.

In the picture frame of the present invention, an elastic ring that can be deformed in the inner diameter direction is interposed between the fixed frame and the movable frame, thereby urging the movable frame in the opening and closing direction.

[0016] Therefore, unlike the above-mentioned improved front-opening-type frame in which the movable frame is biased by using a leaf spring, the movable frame can be prevented from opening even when a slight impact is applied. This eliminates the need to use a strong force when opening and closing the movable frame.

Further, unlike the case where a leaf spring is used, there is an advantage that there is no danger in mounting the ring, and the limit of elastic deformation is larger than that of the leaf spring.

【Example】

 Referring to the drawings, an embodiment of the frame of the present invention will be described. FIG. 1 is a diagram showing a plane of the frame of the embodiment, and FIG. 2 is a diagram showing the frame of the embodiment from the B direction in FIG. FIG. 1 is a front view, in which 1 is the forehead of the present embodiment.

The picture frame 1 of the present embodiment has a square shape as shown in the figure, a corner frame 2 disposed at each of the four corners, and a long frame formed by using the corner frame 2 to form a square shape. There are four fixed frames 3 in the form of a scale, and a movable frame 4 is pivotally supported on each fixed frame 3 so as to be freely opened and closed. The method of framing the fixed frame 3 is not particularly limited. For example, a method of connecting the corner frame 2 and the fixed frame 3 with bolts or a method of connecting them with an adhesive or the like can be considered.

Here, FIG. 3 is a diagram showing a cross-sectional structure of the fixed frame 3 and the movable frame 4, specifically, a diagram showing a cross section taken along the line AA in FIG. 1. In FIG. is there. That is, the fixed frame 3 in the present embodiment has a long groove formed along the longitudinal direction, and this long groove is used as the mounting groove 301. The fixing frame 3 is framed in a square shape with the mounting groove 301 being on the inner peripheral side, and the transparent body 6, the certificate 7 and the end of the back plate 8 are arranged in this insertion groove 301 in this order. It is configured to be inserted at.

On the side of the fixed frame 3 opposite to the mounting groove 301, an extension 302 is formed over substantially the entire area in the longitudinal direction and upwardly perpendicular to the longitudinal direction. A ring receiver 303 capable of holding an end of an elastic ring described later is formed at the tip of the extension 302.

Further, a long shaft plate 304 having a curved portion 305 at a tip portion is provided on a side facing the ring receiver 303 over substantially the entire region along the longitudinal direction.

Next, in the figure, reference numeral 4 denotes a movable frame. In this embodiment, the movable frame 4 is a long object having a substantially U-shaped cross section, and the entire length is substantially equal to that of the fixed frame 3. It is similar.

The movable frame 4 is arranged such that one end portion along the longitudinal direction is opposed to a ring receiver 303 formed on the fixed frame 3. A ring receiver 401 capable of holding one end of the shaft plate 304 is provided, and a curved surface 403 corresponding to a curved surface of the curved portion 305 of the shaft plate 304 is provided on the other end along the longitudinal direction. A slidable bearing 402 is formed on the curved portion 305 along the curved surface, and by engaging the bearing 402 with the curved portion 305, the movable frame 4 is moved relative to the fixed frame 3. It is pivoted. For this reason, as shown in FIG. 4, in the present embodiment, the movable frame 4 can be freely opened and closed with respect to the fixed frame 3. As described above, in this embodiment, the movable frame 4 has a substantially U-shaped cross section. However, the shape of the movable frame 4 is not particularly limited, and the cross section is not necessarily a substantially U-shaped. You don't have to.

Next, FIG. 5 is a diagram showing the state of FIG. 4 in which the movable frame 4 is opened, as viewed from the direction C. In FIG. 5, reference numeral 5 denotes an elastic ring. That is, in the frame 1 in this embodiment, the elastic ring 5 is attached at an arbitrary position between the ring receiver 303 of the fixed frame 3 and the ring receiver 401 of the movable frame 4, specifically, near both ends. Intervening.

Here, the elastic ring 5 will be described. The elastic ring 5 used for the picture frame 1 of the present embodiment is formed of an elastic material such as a deformable metal, rubber, or the like. By pressing the outer peripheral side, the pressed portion and the vicinity thereof are deformed to the inner diameter side, and when the pressing is released, the original shape can be restored. When the elastic ring 5 is mounted, as shown in the figure, the elastic ring 5 is interposed between the ring receivers 303 and 401 while being slightly deformed to the inner diameter side. The movable frame 4 can be biased in both directions of the opening and closing directions.

When a diploma or the like is mounted on the picture frame 1 of the present embodiment configured as described above, first, as shown in FIG. The back plate 8, the diploma 7 and the end of the transparent body 6 are inserted in this order into the insertion groove 301, whereby the back plate 8, the diploma 7 and the transparent body 6 are fixed by the fixed frame 3. Fix in a framed space.

Then, as shown in FIG. 3, the movable frame 4 is rotated toward the space formed by the fixed frame 3, whereby the front plate of the movable frame 4 has a back plate 8, a diploma certificate 7, etc. Then, the position of the back plate 8, the certificate 7, etc., and the position of the transparent body 6 are fixed.

At this time, in the frame 1 of the present embodiment, since the urging force is applied to the movable frame 4 by using the elastic ring 5 that can be deformed in the inner diameter direction, even if an impact or the like is applied to the movable frame 4. The movable frame 4 does not open, and the movable frame 4 can be opened and closed with less force than when a leaf spring is used.

Further, since the elastic ring 5 is used, unlike the case where a leaf spring is used, there is no danger in mounting it.

Further, since the elastic limit of the elastic ring is larger than that of the leaf spring, even if an excessive force is applied to the elastic ring for some reason such as when the elastic ring is mounted, the elastic ring is not deformed. There is an advantage that loss of elastic force is small.

[0032]

[Effect of the invention]

 The frame of the present invention is implemented in the form described above, and has the following effects.

In the picture frame of the present invention, an elastic ring that can be deformed in the inner diameter direction is interposed between the fixed frame and the movable frame in the front openable picture frame, thereby urging the movable frame in the opening and closing direction. ing.

Therefore, unlike the above-described improved front-opening type frame in which the movable frame is biased by using a leaf spring, the movable frame can be prevented from being opened even when a slight impact is applied. This eliminates the need to use a strong force when opening and closing the movable frame.

Also, unlike the case where a leaf spring is used, there is an advantage that there is no danger in mounting the ring, and the limit of elastic deformation is larger than that of the leaf spring.
