Description

  The present invention relates to a replacement picture frame that enables easy replacement of sheet-like exhibits such as photographs.

  With the progress of digital photography, it has become possible to easily create a photo that has been stretched to a free size by a printer without obviating the DPE procedure that was essential for silver halide films. Enlarged photos can be enhanced by putting them in a picture frame. Unlike pictures, photographs produce many works at once, and digital photographs often print out many photographs. It is regrettable to display only one of them in a picture frame, and I want to display all my favorite photos. However, there is a limit to the exhibition space to display many photos. Therefore, if the photos can be easily exchanged for one frame, the photos can be exchanged at any time.

As a frame that allows the exchange of exhibits without opening the back plate of the frame (see Patent Document 1), a configuration that allows opening and closing of the front plate of the frame (see Patent Document 1). Patent Document 2) is known.

  In order to make it possible to replace a sheet-like display such as a photograph contained in a picture frame displayed on a wall, etc., as shown in the prior art, is it necessary to provide an entrance for the display on the side of the picture frame? It may be possible to open and close the front plate of the frame. However, it is not easy to form the entrance / exit on the side surface of the frame if the frame is made of wood or metal. In addition, when taking out the exhibits contained in the frame, it is necessary to pick up and pull out one end of the exhibits, so there is a slot that allows the fingertip to be inserted into the frame, or the exhibition One end of the object needs to be out of the frame, which deteriorates the appearance of the frame, and dust and insects may enter the frame from the entrance. In addition, when the exhibit is put in and out, the display and the transparent window part rub against each other, and if it is repeated, scratches tend to occur on both sides, and if the gap is enlarged so that the display can be taken in and out smoothly, There was a problem that the exhibit was likely to float from the transparent window.

  In addition, with a configuration that allows the front plate to be opened and closed, the surface of the exhibit will be covered and protected, and the glass plate or acrylic plate that will serve as the exhibition window will be opened and closed, and it is necessary to provide a hinge structure and a fixing structure when closed Therefore, there is a problem that the structure becomes complicated.

  The purpose of the present invention is to allow the exchange of exhibits without losing the appearance, and to keep the inserted exhibits in close contact with the transparent windows without causing any strong friction between the exhibits and the transparent windows. It is to provide a replacement picture frame.

  In order to achieve the above object, the first invention of the present application is to close the back opening portion of the frame body having a front side portion as a transparent display window and forming four side surfaces with a back plate at a predetermined interval from the display window. A replacement frame that inserts and removes an exhibit into a gap between an exhibition window and a back plate from an opening provided on a side surface, and holds the exhibit from the opening to the display window and the back plate. A protrusion projecting toward the back plate is provided on the rear end side in the insertion direction of the plate-like body inserted / removed into the gap therebetween, and the back of the position corresponding to the front end side of the inserted plate-like body in the insertion direction is provided. It is characterized by comprising an insertion / removal structure provided with a convex portion projecting on the display window side on the plate. According to this configuration, when the exhibit is configured to be slid and replaced, there is a problem that the exhibit and the transparent plate are rubbed with each other and scratches are easily generated, and the exhibit is likely to float from the transparent plate. Solved. That is, the inserted plate-like body rides on the convex portion provided on the back plate immediately before the insertion end position, and the convex portion provided on the plate-like body rides on the back plate. The exhibit can be brought into close contact with the transparent window. When pulling out the plate-like body from the frame, the convex part provided on the plate-like body is detached from the back plate, and the insertion tip side is detached from the convex part on the back plate. Rubbing and flaws are prevented from occurring in the exhibit and the transparent plate due to repeated replacement of the exhibit without rubbing with the plate in close contact. In addition, since the exhibit held on the plate-like body at the insertion end position is pressed against the transparent plate, the exhibit does not float from the transparent plate, and exhibits exhibiting curls and undulations have good flatness. Arranged on the back of the transparent plate.

  Further, the second invention of the present application is provided on the side surface of the frame body by closing the back opening portion of the frame body having the front portion as a transparent display window and forming the four side surfaces at a predetermined interval from the display window. A replacement frame for inserting / removing an exhibit into and between the display window and the back plate from the opening, and holding the display and inserting / extracting from the opening into the gap between the transparent window and the back plate Protruding portions projecting in the frame side surface direction are provided on the front end side and the rear end side of the plate-like body to be inserted, and guide grooves for guiding the sliding movement of the projecting portion are provided on the inner side surface of the frame body on the insertion end side It is characterized by comprising an insertion / removal structure provided with slide guide means formed so as to curve from the back plate side to the transparent window side. According to this configuration, the plate-like body inserted into the frame body from the side opening is moved along the guide groove, and the guide groove is curved toward the display window immediately before the insertion end position. Therefore, since the plate-like body is guided to the display window side, the plate-like body moves from the position near the back plate to the display window side. Conversely, when the plate-shaped body is extracted, the convex portion is guided and moved by the portion near the back plate of the guide groove, so that the exhibits held on the plate-shaped body rub against the display window during the insertion and removal movement. In this way, it is possible to prevent the display window from being scratched by repeated insertion and removal. In addition, since the inserted exhibits are pressed against the display window side, they are displayed in a flat state without floating from the display window.

  In each of the first and second aspects of the invention, the convex portion is a rolling element, so that there is little sliding friction and the sliding action of the plate-like body is performed smoothly. Moreover, it can suppress that a push-up function falls because a convex part wears.

  In addition, the third invention of the present application is such that the back side opening portion of the frame body having four sides formed as a front display portion as a transparent display window is closed by the back plate, and the display window and the back plate are opened from the opening provided on the side surface of the frame body. A replacement frame for inserting and removing the exhibits in the gap between the display window and the back plate on the side of an arbitrary side except the side provided with the opening and the display window side as a pivot point It is characterized by comprising an insertion / removal structure provided with an exhibit holding plate provided so as to be rotatable and a rotation operation means for operating the rotation of the exhibit holding plate. According to this configuration, when the exhibit holding plate is operated to be inclined toward the back plate by the rotating operation means, a large gap is formed between the display window and the exhibit holding plate. It is easy to insert an exhibit from the opening, and the inserted exhibit slides on the exhibit holding plate and can be inserted to a predetermined position without rubbing against the display window. Therefore, it is possible to prevent the display window from being scratched by repeated insertion / removal of exhibits. After the exhibit is inserted, if the exhibit holding plate is rotated to the display window side by rotating operation means, the exhibit will be pressed against the display window, so the curled or wavy exhibit is flat. Exhibited sexually.

  In the above configuration, the rotation operation means is provided on the lid body that closes the opening so as to be openable and closable, and moves the rotation portion of the exhibit holding plate on the back plate side to the exhibition window side in accordance with the operation of closing the lid body. It is preferable that the push-out member is operated and the push-out member is returned to its original action according to the operation of opening the lid. When the lid is opened to put in and out the exhibit, the push member does not act, so the pivot part of the exhibit holding plate pivots to the back plate and the exhibit is easily rubbed against the display window. When the lid is closed, the exhibit holding plate is rotated by the action of the pushing member, and the exhibit is pressed against the display window.

Further, the replacement frame according to the fourth invention of the present application forms a cutout portion that leads to the rear surface of the display window on an arbitrary side surface of the frame body having the front portion as a transparent display window and has four sides, and the rear surface of the display window. A frame body formed by closing a back opening portion of the frame body with a back plate at a predetermined interval, and a sheet-like display or an exhibition and a mask mount on the plate surface, and an exhibition window from the notch A slide attachment / detachment plate inserted / removed between the back plate and a concave portion formed on the insertion leading end side of the surface facing the back plate of the slide attachment / detachment plate and a convex portion formed on the rear end side of the insertion slide. An engagement push-up means provided with a convex portion corresponding to the concave portion on a surface facing the detachable plate is provided. According to this configuration, when a slide attachment / detachment plate holding an exhibit is inserted on a plate surface from a notch formed on an arbitrary side surface of the frame body, the slide attachment / detachment plate is inserted into a gap between the display window and the back plate. An exhibit is placed behind the transparent display window. Since the slide attachment / detachment plate is simply inserted and removed from the side surface of the frame body, the exhibits can be easily exchanged without removing the frame even when suspended from the wall surface. In addition, since the engagement push-up means is provided, the inserted slide attachment / detachment plate rides on the projection provided on the back plate immediately before the insertion end position, and the projection provided on the slide attachment / detachment plate is the back. Since it rides on the board, the slide detachable plate can be pushed up to the transparent plate side so that the exhibit is in close contact with the display window, and the exhibition window and the slide detachable plate are in close contact during the slide movement Since the concave portion provided in the slide attaching / detaching plate fits into the convex portion provided on the back plate at the insertion end position, the slide attaching / detaching plate is locked at the inserting position.

In the above configuration, it is preferable to provide a lid that closes the notch when the slide detachable plate is inserted to the insertion end position on the rear end side of the slide detachable plate. The formed notch is closed by the lid, and the appearance is improved. When the lid is made of the same quality and color as the frame, the appearance is further improved.

Further, when the transparent plate is arranged so as to cover the surface of the slide attachment / detachment plate, and the slide attachment / detachment plate is attached to the frame, the transparent plate is arranged in the display window portion of the frame body. Exhibits and mask mounts can be inserted on the back of the mask, and mask mounts can be easily replaced.

In addition, the replacement frame according to the fifth invention of the present application is formed in a box shape in which a surface frame portion is formed so as to bulge to the front side around the display window with a transparent resin, and a side portion is provided at a predetermined height. A sheet surrounded by a front frame formed by forming a surface notch portion on an arbitrary side so as to communicate with the rear surface of the display window, and a back frame portion formed in a width that can be fitted inside the front frame portion by an arbitrary color resin When an exhibition storage surface is formed to store the shaped exhibition object and the back frame portion is fitted into the front frame portion, a predetermined interval is formed between the back surface of the exhibition window and the exhibition storage surface. And a back frame formed by forming a back surface notch at a position corresponding to the front surface notch. According to this configuration, when a back frame of any color is combined with a transparent front frame, the back frame is inserted into the front frame to form a frame of any color around the display window it can. By forming a notch that leads to the back of the display window on the sides of the front and back frames, the display is in the gap formed between the display window and the display-receiving surface when the back frame is combined with the front frame. Can be inserted.

In the above configuration, by providing a lid provided with clamping means for clamping one end of a mask mount holding an exhibit or an exhibit inside the exterior of the shape and size capable of filling the surface notch, The cutout portion can be closed by the lid that sandwiches one end of the exhibit or the mask mount holding the exhibit. The exterior can be further improved in appearance by making the exterior approximate to a state in which the front and back frames overlap. Moreover, since one end of the exhibit or the mask mount can be clamped by the clamping means, it is easy to put in and out the exhibit.

Further, the replacement frame according to the sixth invention of the present application is a display case formed in a box shape by opening a back surface with at least a front surface portion as a transparent resin surface and forming a slit or an open portion on an arbitrary side surface, and A back plate that closes the back opening portion of the display case with a required gap between the back surface and the back surface and a lid that closes the open portion of the arbitrary side surface so as to be openable and closable are provided. According to this configuration, when an exhibit or an exhibit held on a mask mount is inserted from a slit or an open portion formed on the side of the display case, the gap formed between the front portion and the back plate of the display case is inserted. An exhibit can be arranged on the front and displayed from a transparent front part. When the side opening part is closed by a lid, the deterioration of the appearance of viewing the opening part is also eliminated.

In the above configuration, the insertion / removal movement path of the exhibit to be inserted / removed from the slit or the open portion or the plate-like body holding the exhibit is on the front side near the insertion end position, and on the back plate side at other positions. When a plate-like body such as a mask mount holding an exhibit or a display is inserted into or removed from the display case, the display or the mask mount rubs against the transparent front part. In addition, when the plate-like body is inserted, the exhibit or the mask mount is pressed against the front portion, so that the exhibit can be displayed with good flatness.

In addition, the frame body is attached so as to cover the peripheral edge and the side surface of the front part of the display case, and the frame body corresponding to the arbitrary side surface is configured as a lid body that can be opened and closed so that it can be opened and closed. The appearance can be obtained. The reduction in strength due to the formation of slits or open parts on the side of the display case is compensated by fixing the back plate to the back open part of the display case, so that the required strength is secured. Can be configured as a decorative body, and can be developed in various appearances by attaching an arbitrary color or pattern.

In each of the above-described configurations, it is preferable to provide posting direction switching means for converting the posting direction of the frame into a vertical position and a horizontal position. The vast majority of exhibits are rectangular, with a mixture of vertical and horizontal positions. Changing the direction of the frame every time the exhibit is replaced or exchanged means that the frame suspended from the wall surface is removed each time, and the meaning of facilitating the replacement of the exhibit by replacement is halved. By providing the posting direction switching means on the frame, it is possible to easily switch the posting direction, set the display position of the exhibit in the direction that can be easily replaced, change the display, and then change the frame. It is possible to easily change to the vertical position and the horizontal position.

  ADVANTAGE OF THE INVENTION According to this invention, even if it is the frame suspended from the wall surface etc., the replacement | exchange frame which can be easily replaced can be provided. When the exhibit is a photograph, it creates a lot of work, and the trend is more pronounced with the development of digital photography. There is a request to exchange and display these works, and to achieve this, instead of removing the frame from the posting position, opening the frame and exchanging the exhibit, if it can be replaced by replacement, exchange of exhibits such as photographs etc. It becomes easy. The problem of the replacement picture frame that allows the replacement and replacement of the exhibit, that is, the problem of scratches caused by the slide movement and the problem that the display is floating from the transparent display window is solved by the configuration of the present invention.

  FIG. 1 shows the configuration of a replacement picture frame 1 according to the first embodiment. Each component is formed by resin molding, but a frame 10 constituting the frame of the replacement picture frame 1 is made of wood, metal, or the like. It is also possible to form by. Here, the frame 10 is integrally formed by resin molding. However, when the frame 10 is made of a relatively large size or is made of wood or metal, the frame 10 is divided for each side of the replacement frame 1. It can be joined at each corner.

As shown in FIG. 2A as a cross-sectional view taken along line AA, a transparent plate 11 formed of a transparent resin (polystyrene resin, methacrylic resin, etc.) is disposed inside the frame 10, and the transparent plate 11 is fixed to the frame 10 by fixing the back plate 12 to the frame 10, and is formed on the frame 9. A notch 15 is formed on one side of the frame 10, and a back plate notch 27 (see FIG. 4) is also formed on the side of the back plate 12 corresponding to the notch 15. Inserting / removing a slide attachment / detachment plate (plate-like body) 6 holding a sheet-like exhibit P such as a photograph into a gap where the transparent plate 11 and the back plate 12 face each other at a predetermined interval from the notch 15. Can do.

  The slide attaching / detaching plate 6 is provided with a holding frame 33 on the front side facing the transparent plate 11 of the slide substrate 16 having an L-shaped cross section so that the mask mount 17 holding the exhibit P can be inserted and removed. Installed. Further, a lid 13 having the same quality and the same color as the frame 10 is joined to the slide substrate 16. On the back side of the slide substrate 16 facing the back plate 12, a lock recess (engagement push-up means) 22 is formed on the insertion tip side, and a push-up projection (engagement push-up means) 23 is formed on the rear end side. Has been.

  FIG. 3 shows the configuration of the back plate 12. A lock projection (engagement lifting means) 25 is formed at a position corresponding to the lock recess 22 formed on the slide substrate 8, and the frame 10 is cut. A back plate cutout 27 is formed on one end side corresponding to the cutout portion 15, and a finger hole 26 for pulling out the slide attachment / detachment plate 6 is formed in the center thereof. The back plate 12 is fixed to the frame 10 by means such as screwing.

  In the above configuration, the slide attachment / detachment plate 6 inserted into the frame 10 can be put on one end of the slide attachment / detachment plate 6 when the fingertip is inserted into the finger hole 26 formed in the back plate 12. The slide attaching / detaching plate 6 can be pulled out from the side surface of the frame body 9. When the mask mount 17 configured as shown in FIG. 4 is inserted into the holding frame 33 provided on the slide detachable plate 6 that has been pulled out, the exhibit P is inserted between the mask mount 17 and the slide substrate 16. The exhibit P can be held on the slide attaching / detaching plate 6 with its periphery covered by the mask mount 17.

  When the slide attachment / detachment plate 6 containing the exhibit P is inserted from the notch 15 of the frame 10, the slide attachment / detachment plate 6 slides on the back plate 12, and the lock convex portion formed on the back plate 12 immediately before the insertion end position. Immediately thereafter, the lock recess 22 fits into the lock protrusion 25, and the slide attachment / detachment mask 8 is locked at the insertion end position. The height of the lock convex portion 25 is slightly larger than the depth of the lock concave portion 22, and the push-up convex portion 23 formed on the slide substrate 16 rides on the back plate 12 immediately before reaching the insertion end position. As shown in (b), the slide attachment / detachment plate 6 is pressed to the transparent plate 11 side, and the mask mount 17 is in close contact with the transparent plate 11.

  On the other hand, when the slide attaching / detaching plate 6 is pulled out, the lock recess 22 and the lock projecting portion 25 are disengaged and the push-up projecting portion 23 comes out of the back plate 12. Is pulled out. That is, when the slide attaching / detaching plate 6 is inserted / removed, the mask mount 17 and the transparent plate 11 do not rub against each other strongly, so that it is possible to prevent the both sides from being scratched. In the case of a frame that has been replaced by slides, and the exchange of exhibits has been simplified, there was a problem that the sliding element and the fixed element rubbed against each other, and both sides were easily scratched. Since a scratch is not generated in a portion where the appearance is hindered, the replacement picture frame 1 that does not cause damage over a long period can be obtained.

  When the slide attachment / detachment plate 6 is inserted into the frame 10, the notch 15 formed on the side surface of the frame 10 is closed by the lid 13 having the same quality and the same color as the frame 10 fixed to the side surface of the slide attachment / detachment plate 6. The appearance of the replacement picture frame 1 is in a state where the notch 15 is not visible. Moreover, the strength reduction of the frame 10 due to the formation of the notch 15 by the insertion of the slide attaching / detaching plate 6 is also compensated.

  In the above configuration, the display P can be replaced or replaced by inserting the display P or the mask mount to which the display P is attached from the cutout portion 15 into the transparent plate 11 without using the slide attaching / detaching plate 6. Is possible. However, it is necessary to separately provide a means for closing the notch 15 and there is no function of bringing the exhibit P into close contact with the transparent plate 11. Therefore, it is used when configuring an inexpensive replacement frame that accommodates the small-sized exhibit P. it can. Further, the slide attaching / detaching plate 6 in the above configuration has a structure in which a thin slide substrate 16 having a raised convex portion 23 is attached to the back surface of a mask mount made of cardboard, and an exhibit is provided between the mask mount and the slide substrate 16. It can also comprise so that P may be clamped.

As shown in FIG. 4, the mask mount 17 used in the above configuration is configured by sticking a front mask 34 and a back mask 35 formed of paperboard, and the back mask 35 corresponds to the size of the exhibit P. A notch 35a is formed, and the front mask 34 is formed with an opening 34a that exposes the display area of the exhibit P inserted into the notch 35a. Further, the front mask 34 is formed such that its three sides are smaller than the outer shape of the back mask 35 and has a thickness such that the surface of the front mask 34 protrudes from the front of the mask holding frame 33 when inserted into the holding frame 33. When the detachable plate 20 is pushed up, it is in close contact with the transparent plate 11 and the exhibit P is in close contact with the front mask 34.

  When the exhibit P is a photograph, the photograph is finished into various standard sizes by DPE for a silver salt film and by a printer for a digital photograph. Since conventional frames are prepared for each size of the exhibition, even if you want to put the finished photo in the frame, you can not frame it unless you have a frame that matches that size. If it is a relatively small size photo that can be finished in general, aside from large size photos, it can be accommodated in one frame regardless of size, and if there is that frame it is finished It can be framed when you think of a photo. You can also finish your photos without having to worry about the size of the picture frame. In order to obtain a replacement frame 1 corresponding to such a plurality of sizes, a mask mount to be applied to each size is prepared for each size.

FIG. 5 shows a configuration of a mask mount 18 suitable for the above-described purpose. In this example, four sizes of printer paper in a digital photograph can be accommodated as an exhibit P. The sizes generally used as printer paper are L size (81 x 127 mm), 2L size (127 x 178 mm), and also KG size (102 x 152 mm). (89 x 158 mm) exists. Many printers used by general users correspond to A4 size or smaller printer paper, and mainly those of 2L size or smaller are used. Here, a frame is not prepared for each size of the printer paper, but a print paper of 2L size or less can be accommodated in one replacement frame 1 by replacement. Further, when the mask mount 18 is a photograph in which the exhibit P is printed out, the back mask 35 is formed of a paperboard that is slightly thicker than the thickness of the print paper, and these are pasted together as illustrated. It can be formed at low cost.

  The mask mount 18 has a structure in which the insertion guide 36 is disposed on the rear mask 35 of the mask mount 17 described above, and is configured by laminating three sheets of paperboard. A back mask 35 in which a notch 35a corresponding to the size of the exhibit P is formed is bonded to the front mask 34 in which the opening 34a for exposing the display area of the exhibit P is exposed, and the exhibit P is placed on the back mask 35. An insertion guide 36 having a notch 36a and a folding line 36b corresponding to the size is pasted. As shown in FIG. 5, when the guide side 36 c separated from both sides by the notch 36 a is opened outward from the folding line 36 b, the insertion guide 36 is in a state in which it is easy to insert and remove the exhibit P on the back side of the front mask 34. It becomes. When the exhibit P is inserted and the guide side 36 c is returned to the notch 35 a of the rear mask 35, the exhibit P is held between the mask mounts 18. When the mask mount 18 is attached as an accessory of the replacement picture frame 1 and a plurality of exhibits P of different sizes are attached, the user inserts the exhibit P to be framed into the mask mount 18 of a size corresponding thereto, and the mask The frame of the exhibition P is completed by a simple operation of mounting the mount 18 on the slide attachment / detachment plate 6 and inserting it into the frame 9. In addition, by preparing a plurality of masks having the same size but different colors of the front mask 34, it is possible to use a color tone that matches the design and color tone of the exhibit P. can do.

  As shown in FIG. 6, the replacement frame 1 having the above-described configuration has a configuration in which the transparent plate 11 is attached so as to cover the exhibition accommodation recess 30 and the mask accommodation recess 31 formed on the surface side of the slide substrate 28. You can also. In a state where the slide attaching / detaching plate 7 is not inserted, there is no transparent plate 11 on the frame body 9 side. When the exhibit P is inserted into the exhibit accommodating recess 30 and the mask mount is inserted into the mask accommodating recess 31, the exhibit P can be arranged in a state where the periphery is covered with the mask mount on the back surface of the transparent plate 11. . Although it is possible to attach the exhibit P to the mask mount with a double-sided tape or the like and insert it separately, only the mask mount can be exchanged if each is inserted separately.

  In this configuration as well, as shown in the first embodiment, the lock plate 25 is formed on the back plate 12, and the lock plate 22 and the push-up plate 23 are formed on the slide substrate 28. Since the slide substrate 28 slides on the back plate 12 in the halfway slide state, the frame 10 and the transparent plate 11 do not rub against each other when the slide attachment / detachment mask 7 is attached / detached. 11 is pressed against the inner edge of the frame 10.

  In each configuration described above, the push-up convex portion 23 and the lock convex portion 22 that are the configurations for pushing up the slide attaching / detaching plates 6 and 7 to the display window side are formed as protrusions on the plate surface, but the sliding operation is smooth. When there is no function or deterioration due to wear, if they are configured so that the arc part of the roller or ball (rolling element) protrudes on the plate surface, the sliding motion will be smooth and the wear will be suppressed. it can.

  Moreover, the slide insertion / removal structure of the slide attachment / detachment plates 6 and 7 shown in each of the above configurations can be a slide insertion / removal structure provided with a guide groove 83 as shown in FIG. As shown in the drawing, a slide guide plate 82 is provided with convex portions 81 on the side of the insertion leading end side and the insertion rear end side of the slide attachment / detachment plate S and guide grooves 83 formed on the upper and lower side surfaces corresponding to the side sides. It is a fixed slide insertion / removal structure. Although only the lower slide guide plate 82 is shown in FIG. 7, a slide guide plate having a similar structure is also arranged on the upper side corresponding to the upper convex portion 81. When the slide attachment / detachment plate S is inserted so that the convex portion 81 fits into the guide groove 83, the slide attachment / detachment plate S slides near the back plate, and the guide groove 83 is curved toward the display window just before the insertion end position. Since the convex portion 81 is guided by the front end curved groove portion 83b and the convex portion 81 is guided by the rear end curved groove portion 83a on the rear end side of the insertion, the slide attaching / detaching plate S moves from the back plate side to the display window side. Also in this structure, the convex part 81 is comprised with a rolling element, The slide movement of the slide attachment / detachment board S becomes smooth, and it can prevent the function fall by wear.

  FIG. 8 shows the configuration of the replacement picture frame 2 according to the second embodiment, which is configured as a resin picture frame suitable for accommodating a relatively small size sheet-like exhibit P. This configuration is simply configured by two components, a front frame 41 molded from a transparent resin and a back frame 42 molded from an arbitrary color resin. As shown in the figure, the surface frame 41 is formed with a surface frame portion 43 whose peripheral edge portion protrudes to the front side, and a plane portion surrounded by the surface frame portion 43 becomes an exhibition window 44 of the exhibit P. Similarly, the back frame 42 is formed with a back frame 45 having a peripheral edge projecting to the front side, and a flat portion surrounded by the back frame 45 contains an exhibit storage unit 46 for storing the exhibit P. It becomes.

  As shown in the cross-sectional view of FIG. 9, the protruding height of the back surface frame portion 45 is formed to be larger than the protruding height of the front surface frame portion 43 from the display window 44. When the frame portion 45 is inserted and the rear frame 42 is combined with the front frame 41, a gap with a predetermined interval is formed between the rear surface of the exhibition window 44 and the surface of the exhibit accommodation portion 46. A front surface notch 47 and a rear surface notch 48 are formed in the same shape on the same side surface of the front surface frame 41 and the rear surface frame 42. When the front surface frame 41 and the rear surface frame 42 are combined, An exhibit entrance / exit passage leading from the notch 47 and the rear notch 48 to a gap formed between the exhibition window 44 and the exhibit accommodation portion 46 is formed. In other words, the exhibit P such as a photograph or the mask mount 17 and the exhibit P can be taken in and out between the combined front frame 41 and the rear frame 42.

  In this configuration, since the front frame 41 is formed of a transparent resin and the back frame 42 is formed of a colored resin, the color of the back frame portion 45 can be seen through from the front frame portion 43 when they are combined. A colored frame is formed around the display window 44. Accordingly, it is possible to easily provide the replacement frame 2 of a plurality of colors by forming the back frame 42 in different colors and combining them with the front frame 41. Further, when a metal color is applied to the surface of the back surface frame portion 45 by means of vacuum plating or the like, a metallic frame can be formed. Further, if a grain pattern or a fiber pattern is applied to the surface of the back frame part 45, a grain or fiber tone frame can be formed.

  Further, when the front frame 41 and the back frame 42 are combined with the sheet of any color or pattern between the front frame part 43 and the back frame part 45, a frame of any color or pattern is formed. The replacement frame 2 can be configured. In addition, the display frame P can be exchanged by configuring the front frame 41 and the back frame 42 so that they can be attached and detached without providing the front notch 47 and the back notch 48, respectively. However, it cannot be denied that the display / removal of the exhibit P is inconvenient.

  In the case where it is not preferable that the replacement frame 2 has an appearance in which the defect portion due to the front surface notch portion 47 and the rear surface notch portion 48 can be seen on the side surface, a lid for closing the defect portion is provided as shown in the above embodiment. Is preferred. However, it is easy to lose the lid simply by providing the lid, and it is troublesome to put in and out the exhibit P. Next, an embodiment for solving this problem will be described.

  FIG. 10 shows an embodiment in which a lid 50 is provided to close the missing portion on the side surface of the replacement frame 2, and the lid 50 has a function of a clamping means for clamping one end of the exhibit P. The exhibit pedestal 51 constituting the lid 50 is formed of the same material and the same color as the back frame 42, and the outer surface has a surface plate (exterior body) 49 formed of the same material and the same color as the front frame 41. It is joined. As shown in FIG. 11, a leaf spring 53 having a V-shaped cross section as shown in FIG. A stop plate 55 having an L-shaped cross section is pivotally supported in a pivotal support hole 54 formed in the side wall.

  Since the stop plate 55 is urged toward the exhibit receiving stand 51 by the leaf spring 53, the tip of the stop plate 55 is pulled up against the bias, and one end of the exhibit P is placed on the exhibit receiving stand 51. When the lifting of the retaining plate 55 is released, the exhibit P is held between the exhibit receiving platform 51 and the retaining plate 55 by the urging of the leaf spring 53. When the exhibit P is inserted between the front surface frame 41 and the rear surface frame 42 and the lid body 50 is pressed and inserted, the lid body 50 is accommodated in the front surface notch portion 47 and the rear surface notch portion 48. The missing part on the side surface due to the notch can be closed. Since the surface of the lid 50 is covered with the surface plate 49 that is the same transparent plate as the surface frame 41 and the surface of the exhibition stand 51 of the same quality and color as the back frame 42, it has the same appearance as the side surface of the frame 3. The missing part caused by the notch is closed without a sense of incongruity.

  By sandwiching the mask mount together with the exhibit P by the lid 50, it is possible to obtain a state in which the exhibit P can be lifted and inserted at the same time. As shown in FIG. 12, the mask mount 56 preferably has a two-fold structure. The display P is fixed to the inner surface of the mount 56a having no opening with double-sided tape or the like, and an opening is formed on the mount 56a. When the frame paper 56b is folded, the main part of the exhibit P can be exposed from the opening. The mask mount 56 is preferably formed to have a size provided with a clamping portion 56 c for clamping by the lid 50, and the exhibit P can be arranged at the center position of the frame 3.

  FIG. 13A shows the structure of the replacement frame 3 according to the third embodiment, and the basic form is the display P from the side of the display case 60 formed in a box shape with transparent resin as shown in the figure. Is configured to move in and out. The display case 60 is formed in a box shape with the back surface and arbitrary side surfaces opened by a transparent resin (methacrylic resin, polystyrene resin, etc.), and the strength reduction that opens the arbitrary side surfaces is suppressed by closing the back surface opening portion with the back plate 61. . The opened side surface is closed by a lid plate 63 so as to be opened and closed.

  Further, as shown in FIG. 13B, the frame 64 can be mounted so as to cover the peripheral edge and the side surface of the front display surface 60 a of the display case 60. The display case 60 itself constitutes a storage case for the exhibit P, and the required strength is ensured by fixing the back plate 61. Therefore, the frame 64 can be easily configured as a decorative body. When the frame 64 is mounted, the side surface portion 64a of the frame 64 located on the open side surface is attached to the lid plate 63, and when the lid plate 63 is opened, the side surface portion 64a of the frame 64 is also opened from the display case 60. Is preferable.

  Moreover, the same replacement structure can be configured even if a slit that allows the display P or the mask mount holding the display P to be taken in and out of the display case 60 is provided instead of opening the entire arbitrary side. it can. Also, the display P can be replaced by holding the display P or the mask mount holding the display P on the back plate 61, and putting the back plate 61 in and out of the open side. In this configuration, when the display P is inserted and removed, the front display surface 60a of the display case 60 and the display P are rubbed against each other to prevent scratching. When the display P is inserted, the front display surface 60a is prevented. The display P is not in a floating state, and an insertion / removal structure is provided for accommodating the display P with curls and undulations with good flatness.

  As shown in a cross-sectional view in FIG. 14, an exhibit holding plate 62 is disposed between a front display surface 60 a of the display case 60 and a back plate 61 that closes a rear opening portion of the display case 60. As shown in FIG. 14 (a), the exhibit holding plate 62 is on the side opposite to the open side and the front display surface side is a rotation fulcrum 62a. The open side surface is inclined to the back plate 61 side, and the exhibit P is inserted into the back surface of the front display surface 60a so as to slide on the exhibit holding body 62. At this time, by setting the inclination of the exhibit holding plate 62 to be sufficiently large, the exhibit P and the front display surface 60a do not rub against each other, and it is possible to prevent scratches from occurring on both sides. As shown in FIG. 15, the pivot supporting point 62a provided on the exhibit holding plate 62 is molded from polypropylene as a resin material, and the pivot supporting point 62a portion is not provided with a hinge structure. When the thin wall is formed, the thin wall portion can function as the rotation fulcrum 62a by the hinge effect of polypropylene.

After the exhibit P is inserted on the exhibit holding plate 62, a wedge-shaped body (extrusion member) 65 provided on the lid 63 is inserted between the exhibit holding plate 62 and the back plate 61, so that FIG. As shown in b), the exhibit holding plate 62 is rotated from the pivot fulcrum 62a and pushed up to the front display surface 60a, and the exhibit P is pressed against the front display surface 60a. Even if undulation is generated, it is corrected, and an exhibition that does not float from the front display surface with good flatness is possible. By inserting the entire wedge-shaped body 65 between the back plate 61 and the exhibit holding plate 62, the side opening is closed by the lid 63.

  In the above configuration, when the exhibit P is accommodated in the full size of the front display surface 60a of the display case 60, a display state like a photographic panel, also called a taiko drum, is obtained. Similarly, when the mask mount with the exhibit P mounted thereon is inserted into the display case 60 in the same manner, a display state like a gallery panel in which the periphery of the exhibit P is surrounded by the mask mount is obtained. Thus, the thickness of the mask mount is different between the case where only the exhibit P is inserted and the case where the mask mount on which the exhibit P is mounted is inserted. If it is about 2 mm, it can be absorbed by elastic deformation of the exhibit holding plate 62 and the wedge-shaped body 65 of the lid 63.

  In the replacement frame 4 having this configuration, a configuration for displaying the exhibit P by the display case 60 is secured, but as shown in FIG. 13B, a frame as a decorative frame around the display surface 60a. 64 can be provided. Unlike a normal picture frame, the space for accommodating the exhibit P is secured by the display case 60, so that the frame 64 can be simply configured as a decorative body.

  As shown in FIG. 14C, when the frame 64 is attached to each side surface of the display case 60, the appearance equivalent to that of a normal frame can be obtained as shown in FIG. 13B. At this time, the frame 64 on the open side surface can be attached to the cover plate 63 of the slide attachment / detachment plate 62. However, as shown in FIG. 14C, the frame portion of the frame 64 is placed on the front display surface 60a of the display case 60. 64b is fixed, and the side surface portion 64a is preferably fixed to the lid plate 63. The frame 64 can be formed into an arbitrary shape and color using an arbitrary material. However, if the frame 64 is formed by resin molding and configured to have a wood grain tone or a metallic tone by surface decoration, the frame 64 can be formed in various appearances. it can.

  When the frame 64 is provided, as shown in FIG. 14C, the display case 60 has only the front display surface 60 a, and the front display surface 60 a, which is a transparent plate material, is provided between the back plate 61 and the frame 64. It can also be configured so as to be held between.

  In the above configuration, the lid 63 provided with the wedge-shaped body 65 is separated from the display case 60 when the exhibit P is inserted and removed, but as shown in FIG. It is also possible to adopt a door-like structure that is hinged on the back side, and to be configured so that the wedge-shaped body 66 can be taken in and out by opening and closing operations thereof. As shown in the figure, the wedge-shaped body 66 is held by the lid 63 so as to be freely movable by a link 67, and the wedge-shaped body 66 inclines from the insertion direction when the lid 63 shown in FIG. An insertion / removal space for the exhibit P, which is placed on the display 63 and inserted into and removed from the exhibit holding plate 62, is secured. When the lid 63 is rotated in the closing direction from this state, as shown in FIGS. 16B and 16C, the wedge-shaped body 66 is pushed up by the lid 63 and at the same time is pushed out by the link 67. The tip is advanced between the exhibit holding plate 62 and the back plate 61. When the lid 63 is completely closed, as shown in FIG. 16D, the entire wedge-shaped body 66 enters between the exhibit holding plate 62 and the back plate 61, so that the exhibit holding plate 62 is displayed. It is pushed up to the front display surface 60a side of the case 60, and the inserted exhibit P is pressed against the front display surface 60a.

  When the lid 63 is opened, the wedge-shaped body 66 is pulled out from between the exhibit holding plate 62 and the back plate 61 by the link 67 interlocking with the rotation of the lid 63, and when the lid 63 is opened at 90 degrees. The state shown in FIG. 16A is established so that the operation of pulling out the exhibit P from the exhibit holding plate 62 or inserting the exhibit P onto the exhibit holding plate 62 is not obstructed.

The rotation operation structure of the exhibit holding plate 62 is not limited to the above-described configuration. For example, as shown in FIG. The projecting portion 91 is rotated by being pressed by an operating shaft 89 provided on the lid 63, and a push-up piece 93 formed on the pushing member 90 is raised to the display holding plate 61 side. The exhibit holding plate 62 can also be configured to rotate. Further, the rotation fulcrum 62a of the exhibition holding plate 62 can be set to the lower position of the replacement frame 3 in the posted state, and a plate or rod-like material having a required thickness is provided on the back plate 61 as a rotation operation means. The exhibit holding plate 62 can be rotated by being inserted and removed.

  In a replaceable picture frame, it is necessary to be able to easily and quickly switch the vertical position and the horizontal position of the exhibit P. Since the replaceable picture frame mainly displays photographs, the photographs to be replaced are often mixed in the vertical and horizontal positions. Switching between vertical and horizontal positions is easy with a tabletop type like a photo stand, but it is not easy to change the vertical and horizontal positions of the picture frame suspended on the wall, etc. Removing the frame from the wall surface every time it is exchanged eliminates the need for a replaceable frame.

  In order to correspond to the vertical position and the horizontal position, the simplest configuration is to make the frame a square. If the frame is square, it can be dealt with by making the mask mount square and cutting the opening according to the vertical and horizontal positions of the exhibit. However, when the mask mount is made square, the difference in the area of the mask mount that can be made on the top and bottom and the left and right of the exhibit becomes large, and it is undeniable that the display state is uncomfortable. Since the majority of the shapes of both photographs and drawings are rectangular, it is preferable that the vertical and horizontal orientations of the rectangular frame can be easily changed in order to frame the frame without a sense of incongruity. Hereinafter, a frame suspension structure in which the vertical and horizontal orientations of the frame suspended on the wall surface or the like can be easily changed without removing the frame from the wall surface will be described.

  As shown in FIG. 18, in the replacement frame A suspended on the wall surface, if the frame A is suspended at a high position, it is difficult to replace the exhibit P from the upper side. The above work shall be performed in the horizontal position indicated by the solid line of the replacement picture frame A. In the case of the display item P in the horizontal position, the suspension position may be used as it is. In the case of the display item P in the vertical position, the replacement picture frame A is used. It is rotated 90 degrees to change to the vertical position indicated by the broken line. That is, the wall surface posting tool (posting direction switching means) is configured so that the horizontal position suspension point B1 can be rotated to the vertical position suspension point B2.

  FIG. 19 shows the configuration of the wall surface marker 71 attached to the back surface of the replacement frame A, which is formed by resin molding, but is formed by metal pressing when strength corresponding to a large frame is required. Can do. As shown in FIG. 20, the wall posting tool 71 is configured to correspond to a forehead suspension screw E having a flange on the head, but the head diameter such as a general nail or screw has a screw portion. If it is formed larger than the diameter, it can be configured similarly.

  In FIG. 19, the wall surface posting tool 71 has a guide groove 73 into which the neck E <b> 2 of the forehead suspension screw E enters on the bottom surface of the rotation groove 72 in which the head E <b> 1 of the forehead suspension screw E enters. A mounting surface 74 is formed. At a position L corresponding to the lateral position of the frame, a screw insertion hole 75 through which the head E1 of the suspension screw E can pass by extending the guide groove 73 and the rotation groove 72 downward is formed. The head E1 of the suspension screw E is inserted into the rotation groove 72 from the screw insertion hole 75 so that the guide groove 73 having a width through which the neck portion E2 of the forehead suspension screw E can pass can be rotated around the suspension screw E. Is formed. Since this wall posting tool 71 is attached to the back plate, it cannot be applied to a normal picture frame in which the back plate is attached to the frame body with only some stoppers. However, in the replacement picture frames 1 and 4, the back plate 12, Since 61 is fixed to the frame main body, the wall surface display 71 can be applied.

  By passing the head E1 of the suspension screw E from the screw insertion hole 75 through the screw insertion hole 75 and placing the head E1 in the rotation groove 72 with respect to the frame suspension screw E attached to the wall surface. The replacement picture frame A can be suspended from the forehead suspension screw E. When the replacement frame A is set to the vertical position, when the replacement frame A is rotated counterclockwise, the position W corresponding to the vertical position of the replacement frame A is guided by the rotation groove 72 and the guide groove 73. When the position E is reached, the replacement frame A is in the horizontal position. In order to rotate the frame A more smoothly, it is preferable to provide a separate support tool that rotatably supports the center position C of the frame A shown in FIG. However, since the bulletin board becomes large in size, it is effective when applied to a large frame A.

  FIG. 21 shows a configuration of another embodiment of the wall surface display 76, in which a circular ring suspension 77 having notches 79 formed in the vertical position suspension point B1 and the lateral position suspension point B2 described above is attached. 78 is configured to be attached to the back plate of the replacement frame A. In this configuration, the ring suspension portion 77 can be hooked from any angle position on the suspension screw E attached to the wall surface, and the neck portion E2 of the suspension screw E is fitted into the notch 79 by turning. The replacement frame A can be suspended in the vertical position and the horizontal position.

  As described above, according to the present invention, it is possible to provide a frame capable of easily replacing and exchanging sheet-like exhibits such as photographs. With the advancement of digital photography, it is possible to create a photo that has been enlarged to a free size, and there is an increasing demand for framing the created photo, but in the case of producing many works at once like a photo, many photos can be created. Although you want to display, there are restrictions on the exhibition space, so if you can exchange photos for one frame, you can change many photos freely. In the conventional frame, it is necessary to remove the frame from the wall and open the frame to replace the exhibit, so it is not easy to replace the exhibit, but in the configuration of the present invention, it is easy to replace the exhibit. The transparent display window and the display do not rub against each other when they are replaced, and scratches do not occur, and when the display has been inserted, the display can be pressed against the transparent display window. Sheet-like exhibits that are prone to wrinkles and wrinkles can be displayed with good flatness. Therefore, a replacement picture frame that satisfies the demand to display many pictures in a picture frame with the spread of digital pictures becomes effective.
