Description

[Detailed description of the invention] This invention relates to the structure of panel joints in overdoors, and in particular, overdoors that open and close entrances and exits by raising and lowering the door, which is made up of a plurality of consecutive panels and has flexibility on one side. In a door, an insertion bank installed on the joint end surface of the other panel is inserted and engaged between a front reception bank and a rear reception bank of different heights that are installed parallel to the joint end surface of one panel of adjacent panels. By forming a gap that is always open at the front part of the opposite bending side between the circumferential joint end faces, there is no risk of fingers getting caught in the joint between the panels when the overdoor is raised or lowered, and the panel To always securely close the front and rear surfaces between.

In general, overdoors are also called over-herad doors, and there are two types of overdoors: - A type in which a large-area inspection board is swiveled above the entranceway, and a door material made by continuously piecing multiple panels is used at the entranceway. There are two types: a type in which the door material is pulled up almost vertically as it is, and a type in which the door material made up of the plurality of panels is pulled up in a curved manner so as to follow the inner ceiling of the doorway.

This invention can be applied to the above-mentioned second or third type of overdoor, but is particularly applicable to the third type of overdoor which is curved and raised along the inner ceiling of the entranceway of a short building such as a house. Ideal for over-door implementation.

Conventionally, the structure of the panel joint in an over door of the type that curves along the inner ceiling of the entrance and pulls up the door material is that the panel joint is continuous in the longitudinal direction of the joint end surface of one panel at both the front and rear ends of the joint end surface. Two parallel real parts are erected, and on the joint end surface of the other panel, a part is inserted between the two real parts when both panels are joined, and extends in the longitudinal direction of the joint end surface in the same way as the real parts. Two consecutive hot water receivers are installed upright, and the two hot water parts are engaged with the outside of the two hot water receivers, and both panels are connected with a hinge so that one side has flexibility. ing.

However, in this conventional joint structure, the panel, which has a certain width in the advance/retreat direction, is rotated at approximately 90 degrees at the upper curved part, so the hot water part and the hot water receiving part are installed upright on the joint end surface of both panels. There is a large opening between the two, and an open opening appears temporarily between the joint end surfaces.

The opening becomes larger as the radius of curvature of the curved portion is smaller, and is closed again after passing through the curved portion.

If this curved part is stored inside a building or if it is considerably larger than a person's height from the floor surface, there will not be much problem other than the possibility of water intrusion, but this There was a big problem when using format overdoors.

That is, when used in a short building, the curved part of the door is not only exposed to the outside, but also the curved part is about the height of a person, so it is difficult to insert your fingertips into the opening between the panels. There were many accidents where people got caught, which caused safety problems.

Furthermore, problems such as rainwater blowing in through the opening when the door is opened and closed on a rainy day have also arisen.

The inventor came up with this idea in view of these problems.

In other words, the purpose of this invention is to improve the safety of opening and closing the door by eliminating the risk of fingers or the like being caught in the joints between panels when opening and closing the door, and to create an overlay that allows the door to be opened and closed easily. The purpose of this invention is to provide a structure for panel joints in doors, and the purpose of this invention is to allow smooth bending and turning between panels, as well as to securely close the front and rear of the joints to prevent infiltration of rainwater, etc. The object of the present invention is to provide a structure for panel joints in an overdoor that has a high waterproof effect to prevent water damage.

For example, as shown in the figure, this invention can be applied to an overdoor in which a door is opened and closed by vertically raising and lowering a door in which a plurality of panels 1 are successively formed with hinges 2 so as to have flexibility on one side, as shown in the figure. , one panel 1a of the adjacent panels 1
On the joint end surface 3 of the other panel 1b, an insertion ring 4 that is biased toward the bent side on the back side of the panel and continues in the longitudinal direction of the joint end surface 3 is provided upright, and on the joint end surface 5 of the other panel 1b, the insertion ring 4 is erected. The insertion ring 4 is slightly inserted into the front melt 6 which is continuous in the longitudinal direction and the rear melt 7 which is parallel to the front melt 6, with both panels la and lb arranged substantially straight. The insertion ring 4 is inserted and sandwiched between the front metal receiving metal 6 and the rear metal receiving metal 7, and a gap 8 is formed in the front part between the joint end surfaces 3 and 5. The present invention relates to a panel joint portion in an overdoor, characterized in that a panel joint portion is formed therein.

An embodiment of this invention will be described in detail below with reference to the accompanying drawings.

1 and 2 are explanatory diagrams showing the structure of the joints between adjacent panels, and FIG. 3 is a partially omitted sectional view of the door.

As shown in the figure, this door is constructed by attaching a hinge to one side of the panel 1, that is, the surface that will be inside the doorway when it is attached to the doorway. It is formed to have flexibility on one side, which is the inside of the entrance/exit.

The overdoor is arranged at both ends of the entrance and exit, but is constructed so that it is placed between idle rails (not shown) and is raised and lowered in the vertical direction to open and close the entrance.

Guide rails generally extend straight upward from the floor at both ends of the entrance to the descending wall above the entrance, and are bent to follow the ceiling near the descending wall and extend to an appropriate length of the ceiling. are doing.

Note that an appropriate number of guide rails may be disposed in the middle of the entrance/exit in the width direction depending on the width of the entrance/exit.

Further, this door is pulled up by an upper shaft (not shown) equipped with a torsion spring (not shown).

In such an overdoor, adjacent panels la, l
An insertion ring 4 is attached to the joint end surface 3 of one panel 1a of b, and continues in the longitudinal direction of the joint end surface 3, that is, in the width direction of the entrance/exit.
has been established.

The insertion ring 4 has a generally wedge-shaped cross section and is provided at the rear of the panel 1a, that is, on the bent side.

Further, on the joint end surface 5 of the other panel 1b, a front receiving metal 6 and a rear receiving metal 7 are provided, which are continuous in the longitudinal direction so as to sandwich the insertion ring 4 at a position facing the insertion ring 4. There is.

That is, on the joint end surface 5 of the panel 1b, there is a pre-receiving hot water 6 on the front side.
A rear hot water bath 7 which is parallel to the front hot water bath 6 and whose height is shorter than the front hot water bath 6 is erected so as to be located on the bent side of the over door, that is, on the rear side.

Furthermore, the height of the insertion ring 4 is shorter than the height of the front hot water bath 6 but higher than the height of the rear hot water bath 7.

The relationship between the heights of the insertion ring 4, the front bath 6, and the rear bath 7 is as follows:
Affects the turning angle when the panels bend and turn relative to each other.

When both panels la and lb are arranged substantially straight on one plane, the insertion ring 4 is inserted and sandwiched between the front hot water 6 and the rear hot water 7.

The gap between the pre-receiving metal 6 and the rear-receiving metal 7 is made appropriately wider than the thickness of the insertion ring 4.

The dimensions between the front hot water tank 6 and the rear hot water tank 7, and the two hot water tanks 6
, 7, and the two receiving metals 6, 7 allow bending and turning between the two adjacent panels la, lb.

The larger this space is, the easier it is to bend and turn both panels la and lb, but if it is too large, rain will accumulate and the waterproofness will deteriorate.

Further, the wedge shape of the insertion ring 4 is effective in making this bending and turning easier.

In addition, 2 in the figure is a hinge, and both adjacent panels la and l
b, and serves as the center of bending and turning between both panels la and lb.

By inserting and sandwiching the insertion ring 4 between the front receiving metal 6 and the rear receiving metal 7 and setting both panels 1a and 1b, a gap 8 is formed in the front part between the joint end surfaces 3 and 5. be done.

This gap 8 opens at the front of the joint between panels 1a and 1b even when the entrance is closed as shown in Figure 1, and it opens even wider at the upper curved part, so it does not matter where the overdoor is located. However, it is always open at the front.

In the figure, 9 is a panel material, 10 is a top material, 11 is a bottom material, and 12 is an elastic member for shock absorption.

FIG. 4 is a diagram showing how the guide roller 13 at the end of the overdoor side is attached, and this guide roller 13 is fitted into the guide rail.

FIG. 5 is a rear view of the panel material, and the panel 9 is in the form of a long strip with wide strips, and a window 14 is bored inside the plate.

As described above, according to this invention, a gap is always formed between the joint end faces of adjacent panel joints, which is always open to the front at any location. Even when opening and closing the over door manually, there is no risk of your finger getting caught in the joint between the panels even if you accidentally insert your finger into the gap, and the door can be opened and closed by direct manual operation. is safe and easy to perform.

Furthermore, since the space between the panels is closed by the insertion ring and the front and rear hotplates installed to sandwich it, bending and turning between the panels can be done smoothly, and the front of the joint Since the rear can be reliably closed, there is no fear of rainwater infiltration, and it is possible to provide a structure of a panel joint part in an overdoor that has a good waterproof effect.
