Description

The present invention relates to a door made of wood panels, and more particularly, to a door formed by pivotally connecting a plurality of wood panels to one another in a height direction and separating a first side from a second side. It is a thing. The door according to the present invention is typically used as a door of an overhead door.

Overhead doors using wood panels are known and are described, for example, in US Pat. At the time of opening and closing the overhead door, a gap is generated between the upper and lower adjacent panels, so a concave portion with a substantially arc shaped cross section is formed at the lower end of the upper panel, and a convex shaped portion with a substantially arc shaped cross section at the upper end of the lower panel The finger pinching prevention is intended by forming such a dimension that the finger does not enter the gap between the concave portion and the convex portion.

However, since the wood panel is wood, deformation at the time of opening and closing (bending, warping, etc.) and age-related deformation (warping, etc. by irradiation of sunlight, drying, etc.) occur, and the lower end of the upper panel There is a possibility that the upper end of the side panel may be rubbed.

The rubbing of the upper and lower panels causes the following problems.
(A) Operation becomes worse by rubbing the panel at the time of opening and closing, and when the overhead door is equipped with overload detecting means, when rubbing is performed, overload detection is performed and the door during opening and closing is stopped. There is a risk of
(A) Abnormal noise occurs when opening and closing.
(C) A hinge is placed on the hinge that connects the panel rotatably through the deformed panel, which may cause breakage of the hinge components or loosening of the screw before reaching the design service frequency. .

An object of the present invention is to solve a problem caused by deformation of a wood panel in a door formed by connecting a plurality of wood panels in a height direction so as to be rotatable relative to each other.

The technical means adopted by the present invention is formed by connecting a plurality of wooden panels so as to be rotatable relative to each other in the height direction, and any two adjacent panels above and below the door separating the first side and the second side. In the wood panel,
The lower surface portion of the upper first panel is a first vertically elongated arc shaped surface extending upward from the first side to the second side, and the upper surface of the first vertically elongated arc shaped surface to the surface portion of the second side of the first panel And an extending first upper surface;
The upper surface portion of the lower second panel is a second vertically elongated arc shaped surface extending upward from the first side to the second side, and a surface portion on the second side of the second panel from the upper end of the second longitudinally elongated arc shaped surface A second upper surface extending to
In the vertical posture, the first upper surface of the first panel is in contact with the second upper surface of the second panel, and the first vertically elongated arcuate surface of the first panel and the second vertically elongated surface of the second panel An arc-shaped space is formed between the arc-shaped surfaces,
The pivot point of the first panel and the second panel is located outside the surface on the second side of the top surface of the second panel and away from the surface on the second side.
It is a door body.
In the embodiments to be described later, the first side is the outdoor side, and the second side is the indoor side.
In one aspect, the rotation fulcrum is a center of a rotation axis of a hinge provided between a lower portion of the second side surface of the first panel and an upper portion of the second side surface of the second panel. It is.

  In one aspect, the lower end of the first longitudinally arcuate surface of the first panel is located on a horizontal surface passing through the pivot point.

  In one aspect, the first elongated arcuate surface is a portion of an elliptical arc provided with a horizontal major axis and a vertical minor axis in a side view.

  In one aspect, the second vertically elongated arcuate surface is a portion of an elliptical arc provided with a horizontal major axis and a vertical minor axis in a side view.

  In one aspect, the pivot point is located at the center of the ellipse.

  In the present invention, the pivot points of the first panel and the second panel are located outside the surface on the second side of the upper surface of the second panel and apart from the surface on the second side. Therefore, when the first panel is pivoted to tilt from the vertical posture with respect to the second panel in the vertical posture, the first upper surface of the first panel separates from the second upper surface of the second panel simultaneously with the start of the rotation When the second panel is turned to be inclined from the horizontal position with respect to the first panel in the horizontal position, the second upper surface of the second panel is the first surface of the first panel simultaneously with the start of the rotation. It separates from an upper surface, and contact and rubbing of panels are prevented at the time of panel rotation (at the time of door opening and closing).

  This effect is achieved by the rotation fulcrum provided on the outside of the second surface of the upper surface of the second panel, and the shapes of the upper and lower surfaces of the panel (the lower surface of the upper first panel is from the first side) And a first upper surface extending from an upper end of the first vertically elongated arc-shaped surface to a second side surface portion of the first panel, the first vertically extending arcuate surface rising toward the second side; The upper surface portion of the panel is a second vertically extending arcuate surface extending upward from the first side to the second side, and a second upper surface extending from the upper end of the second vertically elongated arcuate surface to the second surface portion of the second panel And in combination, and is further increased.

  The pivoting point of the first panel and the second panel is located outside the surface on the second side of the upper surface of the second panel and spaced from the surface on the second side. At the time of panel rotation, a gap is likely to be generated on the indoor side at the time of rotation, but by forming a vertically long arc-shaped surface from an elliptical arc portion provided with a major axis in the horizontal direction and a minor axis in the vertical direction in side view The dimension of the gap which occurs on the indoor side at the time of opening and closing the door is suppressed to a smaller dimension.

As shown in FIG. 11A, the fitting portion 77 between the second plate-like body 71 and the third plate-like body 71 is located substantially at the center of the entire height of the panel 2. When the outdoor side element 7 'is formed of a single plate, the panel 2 may be warped in the indoor / outdoor direction (panel thickness direction) as shown in FIG. 11 (B). In this embodiment, at the fitting portion 77 of the first plate 70, the second plate 71, the third plate 71, and the fourth plate 72, the outer side surface 7301 and the protrusion 740 of the recess 730 are provided. When the indoor side 7302 of the outdoor side, the indoor side 7302 of the concave portion 730, and the indoor side 7402 of the convex 740 contact each other, the first plate-like body 70, the second plate-like body 71, and the third plate-like body 71 Panel 2 by restraining the warping of the fourth plate-like body 72 (see FIG. 11A) and providing one of the plurality of fitting portions 77 substantially at the center of the entire height of the panel 2, The central portion in the height direction of the panel is restricted from expanding in the indoor / outdoor direction (panel thickness direction), and temporarily each of the first plate-like body 70, the second plate-like body 71, the third plate-like body 71, the fourth Even if the plate-like member 72 is slightly warped, the amount of warping in the indoor / outdoor direction (panel thickness direction) when viewed with the entire panel 2 It can be obtained. In the present embodiment, the outdoor element 7 is configured of the first plate 70, the second plate 71, the third plate 71, and the fourth plate 72 having four substantially the same height dimensions. However, the number of plate-like members and the relative height dimension of the plate-like members are not limited to the present embodiment.

Assembling of the indoor side element 8 and joining of the indoor side element 7 and the indoor side element 8 may use known means (biscuit or adhesive) in the assembly of the wooden member. In one aspect, in the manufacturing process of the intermediate panel 2, the contours of the upper surface portion 20 and the lower surface portion 21 of the panel 2 are cut and formed after the outdoor side element 7 and the indoor side element 8 are joined. Specifically, the first plate 70, the fourth plate 72, which form the outdoor element 7, and the upper ridge 80, which forms the indoor component 8, and the lower ridge 81, are respectively rectangular wood having a rectangular shape in cross section. The upper end portion and the lower end portion are cut into a predetermined shape after being prepared as a member and joining the outdoor side element 7 and the indoor side element 8 (in this state, the panel 2 has a vertical rectangular cross-sectional shape) Ru. In addition, the manufacturing process of the panel 2 is not limited to this aspect.

As shown in FIGS. 2 to 4, the vertical ridges 82 of the upper and lower adjacent panels 2 and the central ridges 83 are connected by a hinge 3. The hinge 3 is composed of an upper plate 31 and a lower plate 32 rotatable relative to each other through a horizontal rotation shaft 30, and the longitudinal ridge 82 and the central ridge 83 of the panel 2 on which the upper plate 31 is positioned on the upper side. Of the second surface (interior side portion) 821, 831 with screws and the lower plate 32 is located on the lower side of the vertical ridge 82 of the panel 2 and the second surface portion of the middle rim 83 (interior side portion) Screws are attached to the upper end portions of 821 and 831.

As shown in FIG. 6, the rotary shaft 30 of the hinge 3 is outside with respect to the indoor side surface portion 23 of the panel 2 (not within the thickness of the panel 2 as in Patent Document 1 but with respect to the indoor side surface portion 23 It is located on the indoor side, and the pivot point (rotation center) P of the panel 2 is located on the outer side (indoor side) with respect to the indoor side surface portion 23 of the panel 2, and the indoor side from the indoor side surface portion 23 (See FIGS. 12 to 14). In the illustrated embodiment, the hinge 3 substantially coincides with the lower surface 213 of the lower surface 21 of the upper panel 2 of the upper and lower adjacent panel 2 in the vertical posture, with the horizontal line passing through the rotating shaft 30 (pivoting point P). As such, it is attached to the panel 2.

As shown in FIG. 12, when the vertically elongated arc-shaped surface 200 is assumed to be a virtual intersection point of a horizontal line passing the lower end a1 of the arc and a vertical line passing the upper end b1 of the arc in a side view or a cross sectional view The distance of is larger than the distance between a1-x1, and such an arc-like surface is called a vertically long arc-like surface. Similarly, as shown in FIG. 13, in the side view or cross sectional view, when the virtual intersection point of the horizontal line passing through the lower end a2 of the arc and the vertical line passing through the upper end b2 of the arc is x2, b2 The distance between -x2 is greater than the distance between a2-x2.

An upper surface 211 extends horizontally from the upper end of the vertically elongated arc-shaped surface 210 of the lower surface 21 of the upper panel 2 to the indoor side surface 23, and from the upper end of the vertically elongated arc 200 of the upper surface 20 of the lower panel 2 to the indoor side An upper surface 201 extends horizontally to a horizontal position 23 and is positioned outside the indoor side surface portion 23 on a horizontal line passing through the lower end of the longitudinal arc-shaped surface 200 of the lower panel 2 to set a pivot point P. When the upper panel 2 pivots relative to the lower panel 2 from the upper panel 2 and the lower panel 2 in the vertical posture with the pivot point P as a center, the vertically elongated arc shape of the lower surface portion 21 of the upper panel 2 The upper end b2 of the surface moves upward away from the horizontal plane passing through the abutting upper surfaces 201 and 211, and at the same time the upper surface 211 separates upward from the upper surface 201.

As shown in FIG. 15, in the side view, the vertically elongated arc-shaped surface 200 has a major axis (diameter R1) extending in the horizontal direction and a short axis (diameter R2 <diameter R1) extending in the vertical direction. It forms a part of the provided elliptical arc. In the illustrated embodiment, the portion of the elliptic arc is a portion from the intersection of the horizontal major axis and the elliptical circumference to the intersection of the elliptical circumference and a diameter extending upward at an angle of about 60 degrees with respect to the horizontal minor axis. Longitudinal arc-shaped surface 210 also has a similar shape, and in a side view, a long axis (radius R1 + α) extending horizontally and a short axis (diameter R2 + α <diameter R1 + α) extending in the horizontal direction centering on pivot fulcrum P It forms a part of the provided elliptical arc. The dimension α is an element that determines the groove width of the arc-shaped space S1. In one aspect, R1 = 30.5 mm, R2 = 30 mm, α = 2.5 mm, and the distance between the pivot P and the indoor side portion 23 of the panel 2 is 6.5 mm.

Since the longitudinally arcuate surface 200 and the longitudinally arcuate surface 210 form a portion of an elliptical arc having a major axis extending in the horizontal direction and a minor axis extending in the vertical direction about the pivot point P, the lower surface of the upper panel 2 The movement trajectory of the arc surface of the vertically elongated arc-shaped surface 210 of the portion 21 is a horizontal line passing through the pivot fulcing point P, the inside of the virtual arc plane whose radius R1 + α is the distance between the pivot fulcrum P and the lower end of the vertically elongated arc-shaped surface 210 The gap between the longitudinal arc-shaped surface 210 and the longitudinal arc-shaped surface 200 is maintained substantially constant when the upper panel 2 is pivoted, and the longitudinal arc formed on the indoor side The distance between the arc surface of the surface 210 and the upper surface 201 of the upper surface portion 20 of the lower panel 2 is made as small as possible.

FIG. 14 shows a movement locus of the lower surface portion 21 of the upper panel 2 with respect to the upper surface portion 20 of the lower panel 2 when the upper panel 2 according to the present embodiment rotates with respect to the lower panel 2. . When the vertically adjacent panel 2 is in the vertical posture, the upper surface 211 of the lower surface 21 of the upper panel 2 is in contact with the upper surface 201 of the upper surface 20 of the lower panel 2. When the upper panel 2 rotates with respect to the panel 2, the vertically arcuate surface 210 of the lower surface portion 21 of the upper panel 2 has a groove width of the arcuate space S 1 with respect to the vertically arcuate surface 200 of the upper surface portion 20 of the lower panel 2 It moves in the circumferential direction of the arcuate surface while maintaining (the clearance between the longitudinally arcuate surfaces 200, 210). Similarly, when the door body is in a substantially horizontal storage posture, in the panel 2 closer to the outdoor side and the panel 2 closer to the indoor side, the panel 2 closer to the outdoor side rotates downward with respect to the panel 2 closer to the indoor side. When moving, the vertically arced surface 200 of the upper surface 20 of the panel 2 closer to the outdoor side is the groove width of the arc space S1 (vertical arced surface 200 than the vertically arced surface 210 of the lower surface 21 of the panel 2 closer to the indoor side). , 210) while moving in the circumferential direction of the arcuate surface.

The groove width (clearance) of the arc-shaped space S1 is maintained at such a small size that a person's finger can not be caught from the outdoor side when the panel 2 is rotated, while in the present embodiment it is fully closed. The groove width of the formed arc-shaped space S1 is larger than the clearance of the conventional configuration shown in FIG. 16 while having a size that prevents the finger from being caught.

Thus, even when the panel 2 is deformed (bent, warped, etc.) by increasing the clearance between the longitudinally long arc-shaped surfaces 200 and 210 in the fully closed state, the opening is fully closed (when the door is opened and closed) Also in the case, unnecessary contact and rubbing between the lower surface portion 21 of the upper panel 2 and the upper surface portion 20 of the lower panel 2 are prevented, and problems (deterioration of operability, opening and closing) caused by the contact and rubbing Noise generation and excessive load on the hinges are prevented. Further, by securing a predetermined groove width of the arc-shaped space S1 formed in the fully closed state, between the lower surface 21 of the upper panel 2 and the upper surface 20 of the lower panel 2 when the opening is fully closed. The pressure of the formed gap can be maintained to the same degree as the outside air, and even when it is raining accompanied by the wind pressure, the intrusion of rainwater to the indoor side due to the capillary phenomenon is prevented.

When the upper panel 2 is rotated with respect to the lower panel 2 from the vertical posture, the rotation fulcrum P is positioned outside (outside of the panel thickness) with respect to the indoor side surface portion 23, so the rotation fulcrum is Compared with the case of being positioned within the panel thickness, it rotates so as to draw an arc with a large diameter, and in particular the lower panel at the moment when the upper surface 211 of the lower surface portion 21 of the upper panel 2 starts to rotate. It is lifted and separated so as to escape from the upper surface 201 of the upper surface portion 20 of FIG. Similarly, when the door body is in a substantially horizontal storage posture, in the panel 2 closer to the outdoor side and the panel 2 closer to the indoor side, the panel 2 closer to the outdoor side rotates downward with respect to the panel 2 closer to the indoor side. When moving, the upper surface 201 of the upper surface portion 20 of the panel 2 closer to the outdoor side separates from the upper surface 211 of the lower surface portion 21 of the panel 2 closer to the indoor side at the moment when the rotation starts.

Therefore, even if the panel 2 constituting the door is deformed (bent, warped, etc.), the lower surface 21 of the upper panel 2 and the upper surface 20 of the lower panel 2 when the door is opened and closed. Thus, the rubbing is prevented, and problems (deterioration in operability, occurrence of abnormal noise during opening and closing, excessive load on the hinge, etc.) caused by the rubbing are prevented. On the other hand, in the conventional configuration as shown in FIG. 16 (the pivot point is located within the thickness of the panel), when the panel is deformed, the lower surface portion and the lower side of the upper panel at the time of opening and closing the door. It easily rubs against the upper surface of the panel.

When the upper panel 2 pivots relative to the lower panel 2 from the vertical posture, the vertically elongated arc-shaped surface 210 of the lower surface portion 21 of the pivoted upper panel 2 is positioned indoors and the lower panel 2 There is a gap between the upper surface portion 20 and the upper surface 201 of the As the rotation angle increases, the gap also gradually increases. However, in the present embodiment, the rotation locus of the vertically elongated arc-shaped surface 210 is located inside the arc surface centered on the rotation fulcrum P, as described above. The gap is made as small as possible. Similarly, when the door body is in a substantially horizontal storage posture, in the panel 2 closer to the outdoor side and the panel 2 closer to the indoor side, the panel 2 closer to the outdoor side rotates downward with respect to the panel 2 closer to the indoor side. When moving, the gap formed on the indoor side is made as small as possible.

In the embodiment of FIG. 14, the clearance dimension between the upper surface 201 of the lower panel 2 and the upper surface 201 of the lower panel 2 is c ₁ = about 5 mm, c ₂ = about 6 mm, and 8 mm as a reference for finger pinch prevention The gap is smaller than that, and finger pinching from the indoor side can be prevented. On the other hand, in the configuration of FIG. 17 (a virtual configuration in which the pivot point in the configuration of FIG. 16 is located outside the panel), a gap of c ₃ = about 10 mm is generated on the indoor side. In the configuration of FIG. 16, although the gap c ₄ formed on the indoor side is about 2 mm, there is a possibility that the panels may be rubbed with each other when the panels are rotated.

Finally, the function and effect of the inclined surface 230 will be described. When the door is in the stored position, the guide roller 4 on the upper end side of the top panel 2 '(see FIG. 1) is located in the second guide rail 1' and the upper end of the second panel 2 from the top The side guide roller 4 is located in the third portion 1C of the guide rail 1. The second guide rail 1 'is located immediately above the third portion 1C of the guide rail 1, and the lower end of the uppermost panel 2' is connected to the upper end of the second panel 2 from the top by a hinge 3 In the storage posture, the uppermost panel 2 'and the second panel 2 from the top tend to be in a posture in which the uppermost panel 2' is bent in the opposite direction to the rotation direction because the uppermost panel 2 'is in the inclined posture. When the degree of (2) becomes large, excessive load may be applied to the hinge 3 connecting the uppermost panel 2 'and the second panel 2 from the top and the guide roller 4 of the second panel 2 from the upper. The inclined surface 230 formed in the upper part of the indoor side surface portion 23 of the second panel 2 from the top has a direction opposite to the rotation direction of the second panel 2 from the top with respect to the uppermost panel 2 ′ in the storage posture By providing a relief when flexed, the load will be applied to the hinge 3 connecting the top panel 2 'and the second panel 2 from the top and the guide roller 4 of the second panel 2 from the top Reduce.
