  However, although it has been devised so that the inside cannot be seen, the spaces (w1, w2) formed on the opposite end faces of the suspension panel as shown in FIGS. It could become larger and stuff your fingers in this space, and even small gaps could be a problem, especially for infants with small fingers.

  The present invention has been studied in view of such a situation, and in a panel structure including a front panel composed of a door panel and a hanging panel, the shape of the door panel on the opening side is a semicircle, and the curvature of the semicircle The center is substantially the same as the pivot point of the door panel.

  According to the present invention, the shape of the door panel on the opening side in plan view is a semicircle, and the center of curvature of the semicircle is substantially the same as the rotation fulcrum of the door panel. The gap with the suspension panel is extremely small, the fingers are not stuffed, the appearance is clean, and it looks great. Moreover, by attaching an elastic material as described in claim 3, it can be deformed without breakage, and can prevent finger padding inside.

  Hereinafter, the present invention will be described in detail with reference to the drawings.

  FIG. 1 is an enlarged view of a main part of a toilet booth having a panel structure according to the present invention, and a front panel includes a door panel (10) and a suspension panel (20). FIG. 2 is a cross-sectional view showing the rotating state of the door panel (10), which is an inward opening type.

  The door panel (10) has a thickness of 38 mm and is composed of a core material (11) and a decorative plate (15) covering the surface of the core material (11). The opening side of the door panel (10) has a radius of curvature r of 19 mm. It is processed into a semicircular shape (17). r is the center of curvature.

  As the core material (11), the door panel (10) is lightweight and hollow, such as a paper honeycomb core or roll core, a metal honeycomb core such as aluminum, a foam of a phenol resin or a urethane resin, etc. Structure of so-called flash door in which core material, wood board material such as plywood, particle board, MDF (medium density fiber board), laminated board, LVL, or a composite of these, and plate-like base material are bonded to the front and back The thing which consists of is used.

  The plate-like substrate may be appropriately selected from wood-based materials such as plywood, MDF (medium density fiberboard), or a composite material thereof.

  The surface layer is covered with a decorative plate (15) such as a melamine resin decorative plate, diallyl phthalate resin decorative plate, polyester decorative plate, olefin resin film, vinyl chloride sheet, natural wood decorative plate. In this invention, the melamine decorative board which is excellent in various physical properties, such as impact resistance and killing resistance, is used.

  The distance between the rotation fulcrum s of the door panel (10) and the center of curvature r depends on the thickness of the front panel, but put your finger in the space created between the door panel (10) and the suspension panel (20) when the door panel (10) rotates. The distance between the rotation fulcrum s and the center of curvature r is set to be 5 mm or less so that the respective positions are substantially the same so as not to close them. When the distance is not 0, the object of the invention can be achieved if the straight line connecting the rotation fulcrum s and the center of curvature r is inclined at ± 5 ° with respect to the width direction of the core material (11).

  In Example 1, the straight line connecting the rotation fulcrum s of the door panel (10) and the center of curvature r is parallel to the width direction of the core member (11). FIG. 3 is an enlarged view showing the positions of the rotation fulcrum s and the center of curvature r. The distance between the rotation fulcrum s and the center of curvature r of the door panel (10) is 1 mm, and the center of curvature r is more than the rotation fulcrum s. Located on the hanging panel (20) side. When the rotation fulcrum s is on the side of the suspension panel (20), the semicircular curved surface (17) is caught on the curved surface (21) having a substantially ∫ (integral symbol) shape or the curved surface (31) having a substantially J shape. It becomes easy and obstructs opening and closing of a door panel (10).

  The opening side of the suspension panel (20) has a curved surface (21) whose shape in plan view is a substantially ∫ (integral symbol) shape, and is gently on the surface facing the inner curved surface of the inner door panel (10). The curved surface (21a) and the curved surface (21b) smaller than the gently curved surface (21a) are formed on the surface facing the curved surface on the outside of the inwardly opening door panel (10), and the inside cannot be seen from the gap of the opening. Thus, the curved surface (21) is somewhat inclined.

  The space (W) is somewhat wider between the curved surface (21a) and the curved surface (21a) on the inside of the inwardly-opening door panel (10) so that the influence is reduced even if a finger is sandwiched.

  Further, in the first embodiment, the gap w is set to 2 mm so that the rotation of the door panel (10) is not hindered and the fingers are not closed during the rotation. In this case, although depending on the thickness of the front panel, there is no problem as long as the gap is approximately 1 to 5 mm.

  FIG. 4 is an enlarged view of a main part of a toilet booth having the panel structure of the second embodiment, and FIG. 5 is an enlarged view showing positions of a rotation fulcrum s and a center of curvature r. The difference from the first embodiment is that the position of the rotation fulcrum s is the same as the position of the center of curvature r. As in the first embodiment, finger tightness is prevented and the door panel (10) moves smoothly so as not to be caught by the suspension panel (20) when the door panel (10) is rotated.

  FIG. 6 is an enlarged cross-sectional view of a main part of a toilet booth having the panel structure of Example 3, and a door panel (10) similar to that described above and a curved surface (31) having a substantially J-shape in plan view on the opening side. It is comprised from the suspension panel (30) by which the elastic material (32) was protrudingly provided by the front-end | tip inside a curved surface (31). In Examples 1 and 2, the space (W) was somewhat widened so that the influence was reduced even when the finger was pinched, but the buffering effect of this elastic material (32) has almost no influence even when the finger is pinched. It has become.

  The elastic material (32) is, for example, a molded product having a hollow portion such as soft vinyl chloride or silicone rubber, has a hardness specified in JIS K6301 of 40-60, and a flexural strength specified in ASTM D-813 is 100,000 times or more. Are preferred.

  When there is no hollow part or when the hardness exceeds 60, the elastic material (32) is not easily deformed, and the cushioning effect of the finger pad on the inside is reduced. If the hardness is less than 40, it becomes too soft and it is easy to cause finger padding inside.

  In this embodiment, the toilet booth is specifically exemplified and described. However, the present invention is not limited to the toilet booth, and can be widely applied to doors for buildings, doors for storage furniture, and the like. It will be useful.
