Description

The present invention relates to an overhead door, and more particularly to a door body of an overhead door that has excellent wind pressure resistance.

Overhead doors are known as fittings that are installed at the opening of buildings that connect the outside and inside of buildings such as warehouses and garages, and are designed with consideration given to external pressure (wind pressure from the outside) and rain performance. However, the wind pressure resistance against internal pressure (wind pressure from the indoor side) is not sufficient.

Since it is necessary to endure a predetermined internal pressure depending on the installation location of the overhead door, a means for increasing the strength against the internal pressure is taken. Typically, it is known that a reinforcing member is provided above (inner side of the upper heel) or below (inner side of the lower heel) of the indoor side portion of each section constituting the door body. 1 and 2 disclose a reinforcing member provided on an indoor side surface of the lower arm of the section.

In the modes shown in Patent Documents 1 and 2, the lower arm of the section has a predetermined strength by the reinforcing member, but the upper arm of the section has no reinforcing member, so the strength is weaker than the lower arm, When a large internal pressure is applied to the door body, the lower rod provided with the reinforcing member can withstand, but the upper rod without the reinforcing member may be deformed. In addition, it is difficult to provide reinforcing members on both the upper and lower rods because they interfere when the door body is opened and closed.

This will be described based on Patent Document 1 (FIG. 6) and Patent Document 2 (FIG. 3). In Patent Documents 1 and 2, the lower surface of the upper section and the upper surface of the lower section are: When the doors are each in the shape of a step and the door body is in the closed position, a clearance in the shape of a longitudinal sectional view is provided between the steps in the thickness direction of the section. This is an escape for preventing the section manufacturing accuracy and preventing the sections from contacting each other because the sections adjacent to each other in the vertical direction need to rotate when the door is opened and closed. When internal pressure is applied to the door body, it is sufficient if the force acting on the upper arm of the lower section can be transmitted well to the lower arm of the upper section (strength is increased by the reinforcing member). In the modes of References 1 and 2, when the internal pressure is applied, the upper arm that is weak in strength deforms or moves so as to slide against the lower arm due to the presence of the clearance, and the force acting on the upper arm is reduced well. It cannot be transferred to the heel and distributed by the upper and lower heels. As a result, when a predetermined internal pressure is applied to the door body, there is a risk that the cross-sectional shape of the upper collar is deformed and the effective cross-section is lowered.

When an external pressure is applied to such a door body, the section is inherently provided with a wind pressure resistance against a predetermined external pressure, and therefore the influence of the presence of the clearance is small. In addition, the wind pressure strength increases as the section thickness is increased as compared with the conventional section, but there are various restrictions on increasing the section thickness, which cannot be easily adopted.

Is an element. When the weather strip 8 is attached to the insertion groove 34, the insertion portions 81 and 81 of the weather strip 8 are inserted into the lengthwise ends of the insertion groove 34 and inserted in the length direction. Since the cross-sectional shape was circular like the insertion groove 34, the insertion work of the insertion part takes a lot of work due to friction caused by the surface contact between the circular cross section of the insertion part and the circular cross section of the insertion groove. It was inefficient.

In the present embodiment, when the insertion portion 81 is inserted into the insertion groove 34, the insertion portion 83 is located in the circular portion 340, the base piece 82 is located in the expanded portion 342, and the insertion portion 83 of the insertion portion 81 is By bringing the vertex (contact point) 832 of the first portion into contact (line contact) with the inner surface of the circular portion 340, the vertex 832 is prevented while preventing contact between the second portion and the inner surface of the insertion groove 34 as much as possible. Since the insertion portion 83 of the insertion portion 81 of the weather strip 8 can be inserted into the circular portion 340 of the insertion groove 34 in the length direction using the contact portion of the inner surface of the circular portion 340 as a guide, Workability is better than the mounting method. After the mounting, the second portion having a semicircular cross-sectional view is placed on the inner surface of the lower half of the circular portion 340 of the insertion groove 34, so that it does not fall out.

The interior side has a shape that forms a triangular space (clearance) C2. Hereinafter, a combination of specific shapes of the convex surface of the upper surface 20 of the upper collar 2 and the concave surface of the lower surface 30 of the lower collar 3 will be described.

[First embodiment]
The first embodiment is a fit between the upper surface 20 of the upper collar 2 shown in FIG. 6 and the lower surface 30 of the lower collar 3 shown in FIG. For the explanation, the above description can be used. As shown in FIGS. 3, 13, and 14, in the fully closed state of the opening, the section located on the upper surface 20 of the upper collar 2 of the section 1 located below the two sections 1 adjacent to each other in the vertical direction The lower surface 30 of the lower arm 3 of 1 is placed. The outdoor horizontal surface 300 of the lower surface 30 of the lower rod 3 is placed on the outdoor horizontal surface 200 of the upper surface 20 of the upper rod 2, and the width dimension of the outdoor horizontal surface 200 is slightly larger than the width dimension of the outdoor horizontal surface 300. An indoor horizontal surface 301 of the lower surface 30 of the lower collar 3 is placed on the indoor horizontal surface 201 of the upper surface 20 of the upper collar 2, and the width dimension of the indoor horizontal plane 201 is slightly larger than the width dimension of the indoor horizontal plane 301.

The convex surface 202 of the upper surface 20 of the upper collar 2 is received in the concave surface 302 of the lower surface 30 of the lower collar 3. More specifically, the inclination angle of the outdoor inclined surface 3020 of the concave surface 302 of the lower collar 3 (which rises at 75 degrees from the outdoor horizontal surface 300 in the illustrated example) is the inclination of the outdoor inclined surface 2020 of the convex surface 202 of the upper collar 2. It is larger than the inclination angle (in the illustrated example, it rises at 45 degrees from the outdoor horizontal surface 200), and the outdoor inclined surface 3020 of the concave surface 302 of the lower collar 3 and the outdoor inclined surface 2020 of the convex surface 202 of the upper collar 2 A space (clearance) C1 having a triangular shape in section is formed between the lower surface 3 and the outdoor side portion of the horizontal surface 3022 at the center of the concave surface 302 of the lower collar 3.

The inclination angle of the indoor inclined surface 3021 of the concave surface 302 of the lower collar 3 (rises at 75 degrees from the indoor horizontal plane 301 in the illustrated example) is the inclination angle of the indoor inclined surface 2021 of the convex surface 202 of the upper collar 2 (example illustrated) At 45 degrees from the indoor horizontal surface 201), the indoor inclined surface 3021 of the concave surface 302 of the lower collar 3, the indoor inclined surface 2021 of the convex surface 202 of the upper collar 2, and the lower A space (clearance) C2 having a triangular shape in cross section is formed between the interior surface of the horizontal surface 3022 at the center of the concave surface 302.

The horizontal surface 2022 at the center of the convex surface 202 of the upper surface 20 of the upper collar 2 is close to the horizontal surface 3022 at the center of the concave surface 302 of the lower surface 30 of the lower collar 3 with a gap C3. The width dimension of the horizontal plane 3022 is larger than the width dimension of the horizontal plane 2022. Typically, the outdoor horizontal surface 200 of the upper surface 20 of the upper collar 2 and the outdoor horizontal surface 300 of the lower surface 30 of the lower collar 3 are in contact with each other. The indoor horizontal surface 301 of the lower surface 30 is in contact with the convex surface 202 and the concave surface 302 (the section 1 is a member extending in the opening width direction, and partial deformation or twisting may occur. Therefore, as a result, it does not exclude that the horizontal plane 2022 and the horizontal plane 3022 partially contact in the length direction.)

In this way, the lower surface 30 of the lower collar 3 of the section 1 located on the upper side and the upper surface 20 of the upper collar 2 of the section 1 located on the lower side are located in the outdoor space ( A clearance is formed from the clearance C1, the indoor space (clearance) C2, and the gap C3. The lower surface 30 of the lower collar 3 of the section 1 and the upper surface 20 of the upper collar 2 have a triangular space (clearance) C1 in the sectional view of the outdoor side and a triangular space (clearance) C2 in the sectional view of the indoor side. By forming the clearance, when the door body D is opened and closed, that is, when the upper section 1 and the lower section 1 are rotated, the concave surface 302 of the lower surface 30 of the upper section 1 and the upper surface of the lower section 1 are formed. Movement in a non-contact state with the 20 convex surfaces 202 is permitted (guaranteed), and dimensional errors during manufacture are also absorbed. In the first embodiment, as shown in FIG. 13, the shape of the lower surface 30 of the lower collar 3 of the section 1 and the upper surface 20 of the upper collar 2 is relative to the vertical plane passing through the center of the thickness direction of the section 1. It has a symmetrical shape.

In the space (clearance) C1 having a triangular shape in cross section on the outdoor side, the lower end of the outdoor inclined surface 3020 of the concave surface 302 of the lower collar 3 intersects with the outdoor horizontal surface 300 at an angle (105 degrees), thereby forming the corner E1. The corner E1 is close to the lower end of the outdoor inclined surface 2020 of the convex surface 202 of the upper collar 2.

In the fully closed posture of the door body shown in FIG. 14, surface pressure acts on the door body D, and the lower collar 3 of the section 1 positioned on the upper side relative to the upper collar 2 of the section 1 positioned on the lower side is relatively As soon as it is displaced to the indoor side, the corner E1 formed on the lower surface 30 of the lower collar 3 comes into contact with the lower end or the vicinity of the lower end of the outdoor inclined surface 2020 of the convex surface 202 of the upper collar 2, and is point-contacted in sectional view ( Actually, line contact occurs) (FIG. 15). Since the section 1 is a member extending in the opening width direction, as a mode of line contact, a case where contact is made in the whole length direction and a case where contact is made in a part in the length direction can be considered. In FIG. 15, the corner E1 is in point contact with the lower end of the outdoor inclined surface 2020 of the convex surface 202 of the upper collar 2, but the difference in the amount of deflection due to the difference in strength between the upper collar 2 and the lower collar 3, The corner E1 may make point contact with a portion slightly above the lower end of the outdoor inclined surface 2020 of the convex surface 202 of the upper collar 2 due to torsion or the like due to the 2 and lower collar 3 being elongated in the opening width direction. obtain.

In the room-shaped triangular space (clearance) C2 on the indoor side, the lower end of the indoor inclined surface 3021 of the concave surface 302 of the lower collar 3 intersects the indoor horizontal surface 301 at an angle (105 degrees), thereby forming the corner E2 The corner E <b> 2 is close to the lower end of the indoor inclined surface 2021 of the convex surface 202 of the upper collar 2.

In the fully closed posture of the door body shown in FIG. 14, surface pressure acts on the door body D, and the lower collar 3 of the section 1 positioned on the upper side relative to the upper collar 2 of the section 1 positioned on the lower side is relatively As soon as it is displaced to the outdoor side, the corner E2 formed on the lower surface 30 of the lower rod 3 comes into contact with the lower end or the vicinity of the lower end of the indoor inclined surface 2021 of the convex surface 202 of the upper rod 2, and is point-contacted in a sectional view ( Actually, line contact occurs) (FIG. 16). Since the section 1 is a member extending in the opening width direction, as a mode of line contact, a case where contact is made in the whole length direction and a case where contact is made in a part in the length direction can be considered. In FIG. 16, the corner portion E2 is in point contact with the lower end of the indoor inclined surface 2021 of the convex surface 202 of the upper collar 2, but the difference in deflection amount due to the strength of the upper collar 2 and the lower collar 3 being different, In some cases, the corner portion E2 may make point contact with a portion slightly above the lower end of the indoor-side inclined surface 2021 of the convex surface 202 of the upper collar 2 due to torsion or the like due to the length of the second and lower collars 3 being long in the opening width direction. obtain.

When external pressure or internal pressure is applied to the door D in the fully closed position, both ends in the width direction of the door D are restrained by the guide rails 9, so that the central portion in the width direction swells indoors or outdoors. It is considered to be deformed. At this time, if there is a difference in the strength of the upper collar 2 and the lower collar 3 of the section 1, it is considered that the weaker side (in this embodiment, the upper collar 2) is deformed or displaced more greatly. Therefore, when the internal pressure is applied in the state of FIG. 14, the upper and lower adjacent sections 1 are considered to behave as shown in FIG. 15, and when the external pressure is applied in the state of FIG. Section 1 is considered to behave as shown in FIG. FIGS. 15 and 16 are longitudinal sectional views. Actually, the outdoor side corner E1 and the outdoor side contact portion, and the indoor side corner E2 and the indoor side contact portion are considered to be in line contact with each other. Depending on the deformation, it may be possible to make a partial line contact (for example, only the central portion in the width direction is in contact, and both ends in the width direction are separated).
