[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a photographic frame for relatively large portraits, a back plate of a photographic frame, a fastener for the back plate of the photographic frame, and a photographic frame with a retaining tree.

[0002]

2. Description of the Related Art Conventionally, when a portrait or landscape photograph of a relatively large size is placed in a frame and placed in a room, a transparent glass is placed on the front of the frame in order to prevent the photograph from drying and curling. It is common practice to place a plate or clear acrylic plate and then place the photo, or place a resilient pad on the back of the photo and then place the back plate. However, with the above method, it is not possible to completely prevent the photograph from curling, and for a long time, the surface of the photograph becomes wavy, which often impairs the value of the photograph.
Therefore, a strong adhesive such as an epoxy resin is applied to the entire back surface of the photo and adhered to a plate, surface-treated cardboard, thick acrylic plate, etc., and the photo is fixed to prevent it from curling. ing. Also, various types of frame are used, and there are various frame sizes such as the size and depth of the frame window and the thickness of the back plate.

[0003]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a photographic frame that uses a naturally derived material that does not adversely affect the environment even when it is discarded and that does not warp even after a long period of exhibition. To do.

Portrait photographs and landscape photographs are often displayed for a long period of time. In the first place, photographic printing paper is composed of a photographic emulsion containing gelatin coated on the surface of a high quality paper as a support. Therefore, it is well known that in a photograph, the phenomenon that the photographic paper is warped inward constantly occurs due to the difference in drying degree between the paper and the gelatin layer, and the photograph becomes difficult to see. In order to prevent such an inconvenience, a glass is placed on the front surface of the frame, then a photograph is placed, and the photograph is strongly pressed against the glass surface with a back plate to prevent the photograph from warping. However, over time,
The difference between the degree of drying of the paper and the degree of drying of the gelatin layer is further magnified, and it becomes difficult to completely prevent curling by this method.

Therefore, for portrait photographs and the like, which are planned to be exhibited for a long period of time, the back surface of the photograph is adhered to an acrylic plate or the like in advance with an adhesive to firmly fix it. With this method, it is possible to fix the plate without curling for a considerably long time. However, the acrylic plate used there often has fine cracks due to aging, yellowing, and deterioration of the adhesive, which often adversely affects the photograph. In addition, there is a problem that when such a processed product is discarded, it becomes an industrial waste, and when it is incinerated, harmful substances such as dioxins are generated, which adversely affects the environment.

Further, when only the photographs are replaced without changing the display location of the frame, it is necessary to store the removed photographs as an acrylic plate or the like, or to incinerate them. When storing, it is bulky and takes space, which is inconvenient to store.
There is also a problem that the glued photograph cannot be peeled off and reused. Also, it is possible to change photos regularly or irregularly with the frame display place fixed.
There is a problem in that it takes time and money and cannot be easily replaced. Further, there are various sizes of frame, such as size and depth, and when using a fastener, the fastener may not be available depending on the thickness of the back plate or the frame.

[0007]

The present invention solves the above problems by providing an adhesive raw rubber layer on the back plate of the photographic frame. A conventional frame is used, and the back plate of the frame is improved. The insulation board used in this invention is one that is formed by compressing waste paper or wood chips into a plate shape and finishing the surface to a smooth surface.It is light and can reduce the weight of the frame as a whole, and The metal fittings such as wall surfaces that support the entire weight of the frame are simple, reducing the burden on the wall surface and reducing damage to the wall surface. By reducing the weight, it is possible to considerably reduce the risk of the frame falling due to an earthquake or the like.

The frame of the present invention does not use any material that produces harmful substances that adversely affect the environment. In addition, adhesive raw rubber is used for adhering photos, but since adhesive raw rubber has a strong adhesive force and lasts, curling of photos can be prevented for a long period of time, and pictures can be viewed without curling or unevenness. it can. Also, without changing the display location of the picture frame, you can easily replace the back plate or replace the photos, and even when you no longer need the photos and the back plate, it is composed of natural products. No harmful substances are generated even when incinerated.

The present invention relates to a photographic frame, a waste paper or
Other The insulation board which is processed and formed into a plate shape by compressing wood chips, and glue layer, a paper layer, and the adhesive gum layer and the separator back plate each successive layer deposition to frame photographic comprising of, back This is a photographic frame characterized by being composed of a frame provided with a plate stopper , and an insulation board is a photographic frame whose surface is finished smooth.

[0010]

BEST MODE FOR CARRYING OUT THE INVENTION The frame of the present invention is made of wood. A wooden frame is preferable from the standpoint of environmental issues. A photographic printing paper such as a portrait photograph has a warp due to uneven drying of the surface gelatin layer and the paper layer over time. Thick photographic paper also has a strong warping force, so it is necessary to make adjustments such as thickening the adhesive raw rubber layer. When the photographic paper is thin, it is possible to adjust the thickness of the adhesive raw rubber layer thinly, and it is preferable to make it thin. However,
It goes without saying that the present invention can also be used for photographs in which photographs are printed on a metal plate or a synthetic resin plate, a synthetic resin film, paper or the like. The insulation board, which is the substrate of the back plate, is formed by compressing waste paper or wood chips into a flat plate shape and cutting it according to the size of the frame. In addition, the insulation board has small irregularities on the surface as it is, the adhesion state of the glue layer is bad, and in order to prevent warping of the photograph for a long period of time, the surface of the insulation board is finished with a smooth finish, It is necessary to stack and use a glue layer or the like on the surface. If the surface of the insulation board is not smooth, the adhesive raw rubber layer follows the irregularities of the insulation board, resulting in irregularities on the surface of the adhesive raw rubber layer, and when the photo is fixed, the photo surface will be irregular. become. In addition, if the surface of the insulation board is not finished to be sufficiently smooth, the adhesive layer will deteriorate faster with time, and the duration of adhesion between the insulation board and the adhesive layer will become shorter, and the duration of the effect of preventing warpage will be reduced. Becomes shorter. As a result, there is no occurrence of distortion or warpage due to changes in humidity such as drying of the insulation board, and it is a substantially ideal material for the back plate of the frame. In addition, the insulation board of the back plate substrate can be used repeatedly by removing other layers such as the adhesive raw rubber layer that easily deteriorates, forming each layer again, and repeating.
It is economical. The back plate of the frame is composed of an insulation board, a glue layer, a paper layer, an adhesive raw rubber layer, and a separator, which are sequentially laminated on the insulation board. The glue layer may be omitted and the paper layer may be adhered to the insulation board with an adhesive. The paper of the paper layer needs to have a certain level of strength, and functions to secure the adhesiveness between the glue layer and the adhesive raw rubber layer. The adhesive raw rubber layer may be formed by directly applying the adhesive raw rubber, or an adhesive raw rubber sheet having a separator on both sides may be used.
Further, this adhesive raw rubber sheet is cut together with the separator and processed into the size of the back plate for use. In this case, it is preferable that the separator (paper or the like) is mixed with silicon to enhance the peeling property. It adheres to the back side of the photo and strongly prevents warping over a long period of time, fixing the photo to the back plate. The separator prevents drying of the adhesive raw rubber layer and adhesion of dust and the like, and is convenient for lamination and transportation. Since the adhesive raw rubber layer is in a gel state at all times, it is possible to repeatedly attach and fix photographs, and it is also possible to adhesively fix different materials such as metal plates, synthetic resin plates, synthetic resin films, and paper. There is no change in the adhesive function. The stopper metal has a function of pressing the back plate to prevent the back plate from falling off. In addition, since it can be pressed or released freely, if you change the photos etc., raise the pressing piece,
The back plate can be removed, and after the back plate is fitted, the pressing plate is pushed down, and the back plate to which the photograph is adhered is fixed to and supported by the frame. As means for imparting rotation resistance to the pressing piece, there are a method of bending the center point of the common axis, a method of forming the common axis into a polygon, a method of forming the cross section of the common axis into an elliptical shape, and the like. Either may be adopted and the same effect can be obtained.

It is also possible to fix the back plate to the frame frame with nails or the like using a retaining tree as it is without using the fastener of the present invention. In this case, one side of the stop tree is fixed in advance, and it is possible to select the stop tree or the pad based on this one side. For example, regardless of whether the back plate stopper can be used or not, by selecting and adjusting the thickness of the gap formed by the retaining tree and the back plate fitting and the pad, any frame or Photographs can be posted on any thickness of back plate. The pad material may be sponge, cardboard, wood chips, or the like. Also,
It is also possible to excessively fix the stopper to the frame and use it as a fishing hook through a string or the like. Although the shape of the pressing piece is tongue-shaped, it is not limited to this shape. Further, it goes without saying that the back plate and the back plate stopper can be used not only for a picture frame but also for another general frame.
