JP2010144434A - Cuttable hinge plate - Google Patents

Abstract

<P>PROBLEM TO BE SOLVED: To provide a hinge plate which is cut to a necessary length and size, whereas an existing hinge plate is used for a long time, rusting or squeak noise occur after long-time use since it is formed of metal, and when a hinge plate of size and length matched with the situation is needed in application to a furniture small door or a door, commercially available ones have only fixed standard sizes. <P>SOLUTION: The hinge plate is manufactured by superposing a plastic plate such as a vinyl chloride plate, an acrylic plate or a polycarbonate plate on a plastic sheet resisting to bending frequency. Since cuttable plastic material and synthetic rubber material are used, the hinge plate can be cut in a required size and length by a cutting tool such as scissors. <P>COPYRIGHT: (C)2010,JPO&INPIT

Description

  The present invention relates to a butterfly plate for an opening / closing device used for opening / closing a door or the like.

  Since the commercially available butterfly plate is made of steel, stainless steel, etc., rust or squeaking noise may occur when used for a long time.

  Commercially available butterfly plates are made of steel, brass, stainless steel, etc., which are mainly metallic and have a fixed size.

  When a butterfly plate having a size and length suitable for the application was required, it was a special production order, and the butterfly plate was expensive.

When an existing butterfly plate is used for a door for small items and furniture products, it is necessary to attach a door opening / closing fixture when the door is closed.
JP 11-264274 A JP 09-184354

  It is light and inexpensive, does not generate rust and squeak noise on the butterfly plate, can be cut to the required length, and requires an inexpensive butterfly plate that does not require a door opening / closing fixture.

  The material that makes up the butterfly plate is made of plastic, elastic rubber products, non-metallic materials such as fibers, so that the required length of the butterfly plate can be cut with scissors. it can.

  In addition, because the butterfly plate folding member uses a rubber material that expands and contracts and maintains the function of closing the butterfly plate, the door closes due to the contraction force of the bending member that expands and contracts when the door is opened and closed. Does not require metal fittings to secure the door.

  Since non-metallic members are used as the material for the butterfly plate, the butterfly plate can be manufactured at a low weight and at a low cost, and there are effects such as rust and no squeaking noises when opening and closing.

  A plate or sheet member of a fiber, plastic, or synthetic rubber product that can withstand the bending frequency is provided with a door or a plastic plate member for fixing to the door.

  A wood screw insertion hole is provided in the door and the plate-like member for fixing to the door.

  A plastic sheet member (2) that can withstand the bending frequency is used with a 0.5 mm thick sheet of polypropylene, and laminated on both sides of the sheet (1) 1.0 mm to 2.0 mm thick PVC or acrylic sheet, polycarbonate sheet, etc. Fig. 1 shows a wood screw insertion hole (3) that is bonded with adhesive or double-sided tape.

  It is good also as a butterfly board which can open and close with light force by providing a perforation (4) in a sheet folding part.

  This can be done by increasing the thickness of the folded sheet member (2) according to the size and weight of the door.

  In the production of cuttable butterfly panels for small furniture, the folding sheet width is 25 mm, the length is 300 mm, and a perforation (4) is inserted in the center of the folding part. The width of both sides of the sheet (1) is 10mm, the length is 300mm, and it is attached with an adhesive or laminated with double-sided tape and cut to the required length using scissors etc. 2.

  A perforated cut groove is provided in the center of the folded sheet so that it can be easily bent with a light force. However, the width of the perforated line may be adjusted depending on the application.

  The thickness of the folded sheet is increased according to the weight of the door used, and the width of the perforation may be changed.

  A wood screw insertion hole is provided in the plate-like member that holds the bent sheet portion.

  Fig. 2 shows the length of the butterfly plate that seems to be optimal according to the door to be used and the size of the door.

  You may use the plate-shaped rubber member of the material which expands / contracts a bending sheet member.

  A fiber sheet or a non-woven fabric material may be used as the sheet member that can withstand the bending frequency.

  Figures 5, 6, 8, and 9 may be formed by extruding plastic resin, synthetic rubber, etc. using a mold and thinly forming the center of the butterfly plate to a thickness that can withstand the bending frequency.

  FIGS. 7 and 10 are perspective views of the extruded butterfly plate cut and attached to the door.

  It is a butterfly plate that has a function to close the butterfly plate with a butterfly plate for use in doors and doors of greenhouses and greenhouses that are strictly prohibited to open.

  In order to give the butterfly board the function of closing doors, doors, etc., a plastic sheet member (2) that can withstand bending frequency and a rubber plate member (5) that expands and contracts are used as a butterfly plate. .

  Fig. 11 shows the rubber plate member (5) overlaid with a shorter length than the plastic sheet member (2).

  When the butterfly plate is attached to the door or door, the rubber plate-like member (5) of the butterfly plate extends, so that the butterfly plate is constantly closing, so a fixing bracket is required to close the door and door. Figure 12 and Figure 13 do not.

  FIG. 15 and FIG. 16 may be a butterfly plate in which a rubber material having elasticity is extruded using a mold and shaped like a dogleg.

  When a butterfly plate shaped in a U shape is attached to a door or door, the butterfly plate having a U shape or shape is pushed flat and attached, so that a function of closing the butterfly plate occurs.

  FIG. 17 is a diagram in which a protruding plate member (8) having cushioning elasticity is provided on the upper part of a rubber plate member (5) having elasticity.

  FIG. 17 is a view in which a pressing plate member (7) is provided below the elastic rubber plate member (5).

  Reference figure 21 where the butterfly rubber plate-like member (5) stretches when the door is opened and the butterfly plate closes.

  FIG. 18 is a diagram showing a protrusion-type pressing plate member (8) having cushioning and stretchability that opens and closes while controlling the opening angle when the door is opened.

  Also, without using the elastic rubber plate member (5), the plastic sheet member (2) is used, and the elasticity of the protruding part of the protruding holding plate member (8) with cushioning elasticity is utilized. In addition, the function of closing the butterfly plate may be retained.

  FIG. 19, FIG. 20, and FIG. 21 may be a butterfly plate that is formed by extruding a material that can be cut and stretched using a mold.

  There is an advantage in production such as adding a function to close the butterfly plate without losing the function of the existing butterfly plate, using synthetic rubber, plastic material, etc. As a butterfly plate that can be cut lightly, the range of applications is wider than that of conventional butterfly plates.
