Description

The present invention relates to a frame for attaching exhibits such as paintings, posters, photographs, and certificates.

Frames for attaching sheet-shaped exhibits such as paintings, posters, photographs, and certificates are known. As a general frame, for example, a type as shown in Patent Document 1 and Patent Document 2 can be mentioned. Of these, the frame shown in Patent Document 1 has an outer frame 1 formed in a rectangular frame shape, a cover sheet 2 made of a plastic film, and a rectangular plate-shaped back boat (base) 3. When the exhibit is to be housed in the frame, the exhibit is placed on the base 3 and the outer frame 1 is covered with the cover sheet 2 on the surface of the exhibit, and then the exhibit is arranged on the outer frame 1. The back surface of the base 3 is locked with the stopper 11.

Further, the frame shown in Patent Document 2 includes a base 3 made of thick paper, plastic, a foam material, or the like, a transparent protective cover 5 for covering an exhibit mounted on the base 3, and these bases. It has a frame body 7 attached to the peripheral edge of the base 3 and the protective cover 5, and the frame body 7 is composed of four edge members 9-12 constituting the four sides of the frame body 7 and 4 An L-shaped connecting member 13 that connects vertically and horizontally adjacent edge members is attached to a corner portion. When mounting an exhibit on this frame, the connecting members 13 arranged on both sides of the edge member 9 forming one side of the frame 7 are removed, and the base 3 is slid while pulling the edge member 9. .. Then, the exhibit is placed on the pulled out base 3, the base 3 is returned to the original position, and the removed edge member 9 and the connecting member 13 are reattached.

By the way, in the conventional frame, if the base for stacking the exhibits is formed of resin or metal, a certain strength can be secured, but on the other hand, the weight of the frame becomes large. On the other hand, when the base is made of the thick paper, foam material, or wooden board such as veneer, it is lighter than the one made of resin or metal, but warpage is likely to occur due to moisture or the like. Along with this, there is a problem that the exhibits cannot be mounted flat, or the outer shape of the frame collapses and the aesthetic appearance of the frame is spoiled.

When the slope of the locking claw 24 passes through the inward ridges 6a and 6a, the legs 23 and 23 elastically return to their original states, and the locking claw 24 is locked to the inward ridges 6a and 6a. To. In this locked state, the screen mounting member 21 is in a state in which the screen 20 is pulled into the first mounting groove 6, and the screen 20 is prevented from coming out of the first mounting groove 6. As described above, the screen 20 is pulled into the first mounting groove 6 together with the screen mounting member 21, so that an appropriate tension is finally applied and the screen 20 is mounted on the frame body 2, and the screen 20 is also mounted. The opening 3 of the frame body 2 is covered with the screen 2, and the mounting surface M of the exhibit 50 is formed by the surface 2a of the frame body 2 and the screen 20.

Further, as a result of the stretching work, the screen 20 can be neatly stretched on the frame 2 in a tense state, no wrinkles are generated even if an external force acts after the stretching work, and further, the tension of the screen 20 causes the screen 20 to be stretched neatly. Since the four frames 4 constituting the frame body 2 are pulled toward the opposite sides (that is, the center of the frame body 2), the occurrence of distortion and warpage of the frame body 2 is suppressed as much as possible. Further, since the mesh of the screen 20 ensures the air permeability, the screen 20 is not warped due to the influence of humidity, and the exhibit 50 is light and the flatness of the exhibit 50 is maintained.

Further, as shown in FIGS. 2 and 6-8, when the screen mounting member 21 is fitted in the first mounting groove 6, the outer surface of the lid portion 22 is the surface of the frame body 2. It is configured so as not to protrude outward from 2a, and it is prevented that the lid portion 22 hits the back surface of the exhibit 50 stacked on the mounting surface M and the outer shape of the lid portion 22 is exposed. In the screen 20, the excess portion protruding from the screen mounting member 21 after being pushed into the first mounting groove 6 may be cut by an appropriate length, or the vertical and horizontal dimensions of the opening 3 of the frame body 2 may be determined. A pre-cut screen may be attached to a size of the screen 20 in consideration of the length of the edge portion drawn into the first attachment groove 6.

Next, the holding member 30 for holding the exhibit 50 on the mounting surface M will be specifically described.
The holding member 30 is made of synthetic resin and is arranged along the four sides of the frame 2, the first portion 31 fixed to the outer periphery of the frame 2 and the surface 2a side of the frame 2. It has a second portion 32 having a contact piece 43 for pressing the exhibit 50 to the frame body 2 side, and a hinge 33 connecting the first portion 31 and the second portion 32. The first portion 31, the second portion 32 and the hinge 33 are integrally formed.
The second portion 32 has a holding position (see FIGS. 2 and 8) in which the exhibit 50 is sandwiched between the contact piece 43 and the surface 2a of the frame body 2 with the hinge 33 as the rotation base point. The exhibit 50 is configured to be rotatable and displaceable so that it can be held at the retracted position (see FIG. 6) at which the holding state of the exhibit 50 is released.

The length of the holding member 30 is longer than the length of the frame 4 that frames the frame body 2, and when fixed to the frame body 2, the positioning provided on the corner member 10 that connects both ends of the frame body 4 is provided. It is configured to abut on the piece 11a. Further, in FIGS. 1 and 3, the lengths of the left and right holding members 30 arranged vertically facing each other are longer than the lengths of the upper and lower holding members 30 arranged horizontally facing each other. Since these holding members 30 have substantially the same configuration in other respects, they will be described below as being common to the four holding members 30.

As shown in FIGS. 6-8, the first portion 31 of the holding member 30 is provided with a pair of legs 34, 34 that fit into the second mounting groove 7 formed on the outer periphery of the frame body 2. The pair of legs 34, 34 are provided with locking claws 35, 35 facing each other on the outside of the tip thereof, and the locking claws 35, 35 are provided in the second mounting groove 7. It is locked to the inward ridges 7a and 7a.
Further, the first portion 31 is provided with a recess 36 that opens to the surface 2a side. The recess 36 of the first portion 31 has an inner wall surface 37 on which the leg portion 34 hangs in contact with the outer periphery of the frame body 2, an outer wall 38 arranged to face the outside of the inner wall surface 37, and the frame body 2. On the back surface 2b side of the above, the inner side wall 37 and the outer wall 38 are connected to each other, and the bottom side wall 39 forming the bottom of the recess 36 is formed. The recess 36 has a role as an outer peripheral decorative material that covers the second mounting groove 7 when the holding member 30 is fixed to the second mounting groove 7.

The recess 36 has a receiving claw 40 inside the inner side wall 37 in contact with the outer periphery of the frame body 2. The receiving claw 40 holds the second portion 32 in the holding position by engaging with the hanging claw 42 provided in the second portion 32, which will be described later, and holds the position of the second portion together with the hanging claw 42. It constitutes a mechanism. The receiving claw 40 is provided on the mouth edge of the recess 36 in the inner side wall 37, and has an inclined portion 40a that inclines in an upward gradient toward the depth direction of the recess 36 and a hook portion on the inner end side thereof. It has an engaging step portion 40b that constitutes it. The top where the inclined portion 40a and the engaging step portion 40b intersect is rounded.

On the other hand, the second portion 32 connected to the outer wall 38 of the first portion 31 via the hinge 33 has a rotation cover 41 provided with the contact piece 43 on the tip end side, and the rotation cover 41. A hanging claw 42 that is engaged with the receiving claw 40 is provided at the base end portion of the 41.
The rotating cover 41 is a flat plate-shaped portion that covers the periphery of the exhibit, is connected to the hinge 33, can be rotatably displaced between the holding position and the retracting position, and is located on the holding position side. Occasionally, the boundary between the edge of the exhibit 50 and the surface 2a of the frame 2 is covered to enhance the design.

The hook 42 is an engaging protrusion 42b formed so as to be curved toward the tip end side of the rotating cover 41 from an upright portion 42a provided at a connecting portion of the rotating cover 41 to the hinge 33. When the rotating cover 41 is moved from the retracted position in FIG. 6 to the holding position, the engaging protrusion 42b is inclined in an upward gradient toward the depth direction of the recess 36. The second portion 32 is configured to be held at the holding position by engaging with the engaging step portion 40b constituting the hook portion on the inner end side thereof along the inclined portion 40a of the above. ..

The contact piece 43 is provided on the inner surface side of the rotating cover 41, and is made of an elastically deformable plate-like body that is inclined toward the base end side of the rotating cover 41. The abutting piece 43 is gradually thinned toward the tip thereof, and the tip portion has a shape slightly curved toward the inner surface side of the rotating cover 41. When holding the exhibit 50, the tip portion of the contact piece 43 elastically press-contacts the exhibit 50 stacked on the mounting surface M in a surface contact state as much as possible, and the exhibit 50 is thick. Also, since the corresponding contact piece 43 bends inward (on the rotating cover 41 side) according to its thickness, various thicknesses are exhibited between the contact piece 43 and the frame body 2. It is possible to sandwich the object 50.
Further, the hinge 33 is integrally formed with the first portion and the second portion as an elastically deformable thin plate made of a soft synthetic resin material.

In order to attach the holding member 30 to the frame body 2, both ends of the holding member 30 in the length direction are abutted against the positioning piece 11a for positioning, and the tips of the legs 34 of the holding member 30 and the frame body 2 are used. The second mounting groove 7 and the mouth edge of the receiving recess 11b of the cap portion 11 connected to the second mounting groove 7 are confronted with each other. In that state, the outer surface of the outer wall 38 that partitions the recess 36 is pressed toward the second mounting groove 7 and the receiving recess 11b. Then, the slope of the locking claw 35 formed on the leg portion 34 hits the inward ridges 7a, 7a of the second mounting groove 7, and the leg portions 34, 34 are elastically deformed inward, and the locking claw 35 is formed. When the whole of the legs passes through the inside of the inward ridges 7a and 7a, the legs 34 and 34 elastically return to the original state, and the locking claws 35 are locked to the inward ridges 7a and 7a. In this way, the leg portion 34 is pushed into the second mounting groove 7 and the receiving recess 11b, and the holding member 30 is mounted on the frame body 2.

Next, a case where the exhibit 50 is held by the holding member 30 will be described.
First, as shown in FIG. 6, the second portion 32 of the holding member 30 is opened and positioned at the retracted position, and the exhibit is placed on the mounting surface M composed of the screen 20 and the surface 2a of the frame 2. Place 50. Then, the rotation cover 41 of the second portion 32 is rotated from the retracted position to the holding position. At this time, as shown in FIG. 7, the engaging protrusion 42b of the hanging claw 42 rides on the inclined portion 40a of the receiving claw 40 of the first portion 31, so that the receiving claw 40 and the hanging claw 42 are pressed against each other. In addition to being elastically deformed as a whole, the soft and thin plate-shaped hinge 33 is elastically deformed to allow the engaging protrusion 42b to rise with respect to the inclined portion 40a.

Then, when the rotation cover 41 is further rotated toward the holding position, the engaging protrusion 42b slides on the inclined portion 40a toward the top of the inclined portion 40a, and the top of the inclined portion 40a The engaging protrusion 42b and the engaging step portion 40b are engaged with each other (see FIG. 8). In this engaged state, the second portion 32 is held in the holding position, and the exhibit 50 is elastically placed between the outer surface of the contact piece 43 provided on the rotating cover 41 and the frame body 2. Be pinched. By doing this for each holding member 30 arranged on the four sides of the frame body 2, the exhibit 50 can be held on the mounting surface M.

When the exhibit 50 is removed from the frame 1, the engaging protrusion 42b of the hanging claw 42 is disengaged from the engaging step portion 40b of the receiving claw 40. By doing so, due to the action of the elastic contraction force after stretching in the hinge 33, the rotating cover 41 is displaced from the holding position toward the retracting position through the procedure opposite to the above-mentioned procedure, and the exhibit 50 The pinched state is released, and the rotating cover 41 is opened to the retracted position to remove the exhibit 50. When the engaging protrusion 42b is disengaged from the engaging step portion 40b, the top portion where the inclined portion 40a and the engaging step portion 40b of the receiving claw 40 intersect, and the engaging protrusion 42b of the hanging claw 42. Since the tip is rounded, it can be smoothly detached without requiring excessive force.

Although the picture frame according to the present invention has been described above, it is needless to say that the present invention is not limited to the above-described embodiment and various design changes can be made without departing from the spirit of the claims. ..
For example, in the present embodiment, the holding member 30 is fixed to the frame body 2 in advance, but after mounting the exhibit 50 on the mounting surface M, the holding member 30 is fixed to the frame body 2 afterwards, and then the first The two portions 32 can also be displaced and held from the retracted position to the holding position. Further, the structure of the holding member is not limited to the present embodiment in which the first portion 31 and the second portion 32 are connected by a flexible hinge 33, and the exhibit 50 is pressed against the frame body 2. As a result, any configuration may be provided as long as it can be finally held on the mounting surface M.
