Display panel and hinge structure

Abstract

To improve the durability of the part of the hollow structure that supports the hinge shaft member. [Solution] In the display panel 10 of this disclosure, a leg portion 71 is rotatably connected to a hollow base portion body 11H. The rear wall 11B and front wall 11A of the base portion body 11H are provided with a rear wall corrugated portion 20 and a front wall corrugated portion 24, which have a corrugated shape in the cross-section and face each other. The upper part of the leg portion 71 is positioned between a pair of rear wall peaks 21 that protrude outward from the rear wall corrugated portion 20. A pair of front wall peaks 25 that protrude inward from the front wall corrugated portion 24 are received inside a pair of rear wall peaks 21, and a hinge bolt B2 passes through the pair of rear wall peaks 21, the pair of front wall peaks 25, and the upper part of the leg portion 71.

Claims

1. A display panel having a hollow panel body to which legs are rotatably connected, and which can be raised to stand upright relative to the panel body by opening the legs, The rear wall and front wall of the panel body are formed with a corrugated rear wall portion and a corrugated front wall portion, which have a corrugated shape in their flat cross-section and are facing each other, Among the corrugated portion of the rear wall, which is included in a plurality of outwardly protruding peaks, a pair of rear wall peaks facing each other with the upper part of the leg portion in between, A pair of front wall peaks, which are included in a plurality of inwardly protruding peaks of the front wall corrugated portion and are received inside the pair of rear wall peaks, A display panel comprising a hinge shaft member that penetrates both the pair of rear wall ridges and the pair of front wall ridges, and rotatably connects the leg portion to the panel body.

2. The display panel according to claim 1, wherein the top of at least one peak of the front wall corrugated portion is connected to the back side portion of the top of the peak of the rear wall corrugated portion, or the middle portion of at least one peak of the front wall corrugated portion is connected to the back side portion of the middle portion of the peak of the rear wall corrugated portion.

3. The display panel according to claim 1 or 2, wherein the panel body includes a base portion which is a plate-shaped blow-molded product, and a frame which is a frame-shaped blow-molded product that fits to the outside of the base portion and has a front support portion that overlaps the front outer edge of the base portion, and a display sheet with characters or a design can be supported by being sandwiched between the base portion and the front support portion.

4. The display panel according to claim 3, wherein the rear wall waveform portion and the front wall waveform portion are provided on the base portion.

5. A display panel having a hollow panel body to which legs are rotatably connected, and which can be raised to stand upright relative to the panel body by opening the legs, The rear wall of the panel body has a rear first curved portion that curves inward and protrudes, with the outer surface having an external vertical groove that receives the upper part of the leg portion. The front wall of the panel body has a front first curved portion formed thereon, which is curved to protrude outward, and whose inner surface has an internal longitudinal groove that receives the rear first curved portion. A display panel comprising a hinge shaft member that penetrates both the rear first curved portion and the front first curved portion, and rotatably connects the leg portion to the panel body.

6. The rear wall of the panel body has a rear second curved portion that curves outward and shares one side with the rear first curved portion. The front wall of the panel body has a front second curved portion that curves inward, shares one side with the front first curved portion, and is received inside the rear second curved portion. The display panel according to claim 5, wherein the hinge shaft member passes through the rear second curved portion and the front second curved portion.

7. A hinge structure in which a second component is rotatably connected to a first component with a hollow structure, The first component has a first wall and a second wall facing each other across an internal space, and the first wall corrugated portion and the second wall corrugated portion have a corrugated shape in their flat cross-section and face each other, A pair of first wall peaks, which are located within a plurality of outwardly protruding peaks of the first wall corrugated portion and facing each other with a part of the second component in between, A pair of second wall peaks, which are included in a plurality of inwardly protruding peaks of the second wall corrugated portion and are received inside the pair of first wall peaks, A hinge shaft member that penetrates both the pair of first wall ridges and the pair of second wall ridges, and rotatably connects the second part to the first part, A hinge structure equipped with [a specific feature].
