Abstract

(57) [Summary] [Purpose] This invention is to install an exhibit from the surface of the display panel, etc., and to easily fix the transparent acrylic plate, etc., which protects the surface to the panel surface. It is an acrylic plate fixing bracket that facilitates replacement of the acrylic plate. [Structure] An acrylic plate (3) provided with circular holes (e) at four corners is placed on the surface of a panel (4) on which works to be displayed are arranged, and the panel is placed from above and almost from the center of each hole. The fixing wood screw (1 or 7) of the present invention is fixedly attached to (4), and the acrylic plate (3) is fixed in the lateral direction. Further, by attaching a decorative holding lid (2) thereon, the fixing wood screw (1 or 7) can be hidden, and the front and rear of the acrylic plate (3) can be fixed while decorating the surface. . The fixing bracket according to the present invention is characterized in that the acrylic plate (3) can be easily fixed from the front part even in a panel shape having no frame outer frame, and the work (8) surface can be protected.

Description

[Detailed description of the invention]

[0001]

[Industrial applications]

 In the present invention, a transparent acrylic plate (3) for protecting works is easily attached and fixed to the frame outer frame (9) or the panel surface (4) from the front side, mainly in the frame or panel for displaying calligraphy etc. The present invention relates to a metal fitting which is possible and can be easily removed.

[0002]

[Prior art]

 Conventionally, in a normal frame, as shown in FIG. 9, an acrylic plate for protecting works and a glass plate (3) are mounted from the back of the frame outer frame (9). The conventional method for fixing the acrylic plate (3) from the front is similar to the present invention, but holes (e) are made at four corners of the acrylic plate (3) as shown in FIG. There was also a method of fixing the acrylic plate (3) and the panel (4) by making a hole in the same position in (4), penetrating a bolt-shaped wood screw and tightening the front and back.

[0003]

[Problems to be solved by the invention]

 However, the above-described conventional method requires a frame outer frame (9) for receiving an acrylic plate (3), a panel (4), and the like from the back side because of the frame structure. The specification for fixing the acrylic plate (3) and the panel (4) is such that the hole (e) is pre-penetrated at the same position on both the acrylic plate (3) and the panel (4) or the panel (4). Processing to install parts in advance on the side was required.

The present invention solves the above-mentioned drawbacks, and can fix the acrylic plate (3) from the front part even in a panel shape without the frame outer frame (9), and can protect the work surface. Further, the present invention provides a metal fitting which can simplify the number of steps compared with the conventional method, and can be easily mounted and fixed without pressing the acrylic plate (3) more than necessary. It is the purpose.

[0005]

[Means for Solving the Problems]

 In order to achieve the above object, according to the present invention, an acrylic plate (3) having circular holes (e) formed in advance at four corners is applied to the surface of the panel (4), and then each of the holes (e) is substantially centered. The fixing wood screw (1) is fixed to the core with a tool to control the lateral movement of the acrylic plate (3). The helical cut groove (a) provided on one side of the fixing wood screw (1) is covered with a plated or decorated holding lid (2), and then rotated and squeezed to tighten. Hide the wood screw (1) and hold the acrylic plate (3) in place without losing the beauty of the surface. In addition, when the presser lid (2) is put on the end of the fixing wood screw (1), the end of the fixing wood screw (1) comes into contact with the bottom surface inside the presser lid (2), and an excessive pressure is applied to the acrylic plate. Since it is not added to (3), the bending due to expansion and contraction of the acrylic plate (3) can be reduced, and the surface of the acrylic plate (3) is not tightened, so that it is not damaged.

[0006] In order to remove the acrylic plate (3) from the panel (4), if the holding lid (2) is rotated several times in the opposite direction to the fixing when it is fixed with bare hands, the fixing is released and the holding lid (2) is released. Since the acrylic plate (3) is released and the front and rear fixing of the acrylic plate (3) is released, the acrylic plate (3) can be removed to the front side along the end of the fixing wood screw (1).

[0007] In the specific configuration, the acrylic plate (3) is fitted into four corner holes (e) to control the lateral movement of the acrylic plate (3) with respect to the panel (4) so as to be fixed. Two points: a fixing wood screw (1) and a holding lid (2) for decorating the surface of the fixing wood screw (1) and fixing the movement of the acrylic plate (3) from the panel (4) side to the front. It is composed of The fixing wood screw (1) is composed of two independent members, a fixing cylinder (5) and a wood screw (6) for fixing it to the panel (4), or the fixing cylinder (5) and the wood screw (6). The same fixing method is possible with any shape of the special wood screw (7) that integrates (1). The fixing cylinder (5) constituting the fixing wood screw (1) is cylindrical and has a spiral cut groove (a) on one side surface for fixing the holding lid (2). In the center, there is a circular hole (d) for passing a wood screw (6). The presser lid (2) is a lid type and the surface is colored or decorated with plating or the like. The inner portion has a cylindrical hole corresponding to the fixing cylinder (5) at an appropriate depth, and has a spiral cut groove (a ') on the inner side surface.
