Description

[Detailed Description of the Invention] The present invention relates to a seat strip door formed by suspending a large number of elongated seat strips, and in particular, the seat strips can be gathered to one side of the door to open the door as required. This invention relates to a strip door that can be opened and closed.

Seat strip doors are convenient in that even people carrying luggage or vehicles can pass through by pushing aside the strip in the necessary area without having to open the entire door. However, when necessary, such as when cargo movement is rapid and passes through the door many times,
Recently, retractable strip doors have been developed that allow the door to be opened by gathering a number of sheet strips suspended across the width of the door and gathered to one side. However, in many of these, due to the opening/closing mechanism, it is not possible to increase the overlapping area between adjacent sheet strips when the door is closed. Sheet strips are typically several meters long and often warp. Therefore, as mentioned above, if the overlapping portions of adjacent sheet strips are small, gaps will be created between the warped portions of the sheet strips, reducing the effects of heat retention, dust prevention, etc. Furthermore, in conventionally known seat strip doors (including those that open and close), each seat strip is hung by directly fixing it to a hanging fixture set above the door. Therefore, it is not always easy to lift a relatively heavy seat strip several meters above the ground for installation and replacement work.
Usually requires two or three workers.

In view of the above-mentioned points, the present invention enables the overlap of adjacent seat strips to be increased when the door is closed in a retractable seat strip door, and also facilitates the installation work of the seat strips. To provide a seat strip door that can be operated by one person.

Hereinafter, the present invention will be described in detail based on embodiments shown in the accompanying drawings.

As shown in FIG. 1, the seat strip door 10 according to the present invention includes a pair of link members 12, 14.
A plurality of link pairs 16 are sequentially formed by intersecting each other at their center portions and pivoted to each other by pins 15.
So-called telescopic arms (lazy
tong) mechanism; a strip hanging member 20 attached to the mutually parallel link members 14 of one link member of each link pair; and a strip hanging member 20 that is removably latched to the hanging member and suspended. a sheet strip 22; a roller 24 as a telescopic arm hanging member which is rotatably attached to the central pin 15 of each link pair; and a roller 24 which is attached above the entrance of the building where the sheet strip door is installed. , a telescopic arm support guide member 26 that receives and supports the roller 24 and guides the roller 24 in the direction of expansion and contraction when the telescopic arm mechanism is expanded and contracted;
It is equipped with and;

The guide member 26 is a tubular member extending along the direction of expansion and contraction of the telescoping arm mechanism, and has a downward elongated opening 30, and receives the roller 24 on roller receiving portions 32, 32 on both sides of the opening 30. The pin 15 to which the roller is attached is brought out downward from the opening 30 to hang the telescopic arm mechanism. A pin 15 at one end of the telescopic arm mechanism, for example, the left end pin in the illustrated example, is fixed to a guide member 26 without a roller 24 attached thereto. Therefore, the link pair 16 at the other end of the telescoping arm mechanism, the right end in the illustrated example.
By moving the right end portion 12' of the link member 12 in the direction of extension and contraction of the telescoping arm mechanism, the telescoping arm mechanism as a whole is extended and contracted, and the door can be opened and closed.

As shown in FIGS. 1 to 4, the strip hanging member 20 has semicircular portions 36 on both left and right sides.
and a substantially circular central portion 38, and a portion 40 extending parallel to each other at the top of each portion narrowly connects the downwardly extending portion 14' of the link member 14 in the telescoping arm mechanism. Welded.
The semicircular and circular portions each have a length of about one third of the hanging member. Each semicircular portion 36 is provided with two approximately T-shaped openings 44 in its arcuate portion 42.
8 has two openings 45 formed into a T-shape on both sides and continuous into an I-shape at the center of the lower part.

On the other hand, two strip support members 46 each consisting of a pair of rectangular plates are attached to the upper edge portion of each sheet strip 22. Each strip support member has a T-shaped engagement protrusion 48 that projects upwardly and is spaced a predetermined distance apart from the upper part of the strip support member.
It is narrower than the wide portions 44', 45' of the opening 45, and wider than the narrow portions 44'', 45'' of the same opening.

To suspend the sheet strip from the suspension member 20, the wide portion 50 of the strip locking member 48 is suspended through the wide portions 44', 45' of the openings 44, 45 as shown. To remove the sheet strip, the wide portion 50 of the locking member is pulled out from the wide portions 44', 45' of the openings 44, 45 in the opposite manner as described above. In the illustrated embodiment, each strip suspension member 20 has two sheet strips 22 having a width approximately two-thirds the width of the suspension member and a width of approximately one-half the width of the sheet strips 22 from each side of the suspension member. It is locked by shifting from side to side.

The strip hanging member 20 has link members 12,
14 extends outwardly from the pivot point at the end of the link members 12, 14, in the illustrated example, from the location of the pivot pin 18 of the link members 12, 14, as shown in FIG. It extends approximately half the length of the circular portion 36 on both sides. Therefore, when the telescoping arm mechanism is fully extended as shown in FIG. 6, that is, when the seat strip door is closed,
As shown in FIGS. 2 and 7, adjacent strip suspension members 20 have their semicircular portions 36 overlapping along their entire lengths. Therefore, the seventh
As shown in the figure, adjacent sheet strips in this state overlap each other by about half of their widths. To open the seat strip door from such a state, as described above, move the end 12' of the link member 12 of the telescoping arm mechanism to the left in FIG. The arm mechanism retracts as a whole, and eventually each strip suspension member, and therefore the seat strip latched thereto, is brought together to the left and the seat strip door is opened.

As mentioned above, in the opening/closing seat strip door according to the present invention, a so-called telescopic arm mechanism is used as the opening/closing mechanism, and one of each link pair 16 consisting of intersecting link members constituting the mechanism is used. A seat strip is attached to a link member 16 which is parallel to each other with link members 16, and the seat strip is extended outwardly from a pivot point with another pair of links at each end of this link member 16, that is, from the position of a pin 18. Since it was set up over a wide range,
When the telescoping arm mechanism is extended and the door is closed, adjacent sheet strips will overlap approximately twice the width of their outward extension from the pins 18. Therefore, the amount of overlap can be easily increased.

In addition, when suspending the sheet strip 22, the required number of strip support members 46 are attached to the strip on the ground, and this can be set simply by engaging the strip suspension members 46 that have been attached to predetermined positions. Therefore, the setting and replacement work is extremely easy compared to conventional ones.
It can be done even by one worker.
