JPH0631114Y2 - Seat gate with slits for draft - Google Patents

Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a seat gate installed at an entrance / exit of a construction site or the like, and more particularly to a seat gate having a wind vent slit.

[Prior Art] Conventionally, some seat gates provided with this kind of slits for venting have a slit in the longitudinal direction at the fold portion.

[Problems to be solved by the invention] However, as a seat gate of this type, usually, two upper and lower sheets are stretched between bar members, and these end portions are slightly overlapped, so that the upper sheet is In some cases, both sides of the lower end were separated from the bar material to form ventilation slits.

However, when the conventional sheet is opened by wind, not only the bar is exposed and the appearance is unsightly, but also the lower end of the sheet is light and flutters constantly, and the blinding effect is insufficient. It was

The present invention has been made in order to solve the above-mentioned conventional problems, and an object thereof is to provide a seat gate having a wind vent slit that sufficiently maintains a blindfold effect and is not unsightly in appearance. To do.

[Means for Solving the Problems] In the seat gate having the slits for drafting according to the present invention, a blind cut cloth portion is formed so as to be capable of being folded back to the upper side by making a die notch in the sheet tension portion between the bar members, and the above-mentioned sheet. It is characterized in that a threaded edging portion is provided at the cut edges of the stretched portion and the blindfolded cloth portion, and a metal plate or thick cloth is attached to the lower edged edged portion of the blindfolded cloth portion.

[Embodiment] An embodiment of the present invention will be described below with reference to the drawings.

In FIG. 1, 1 is a pillar and 2 is a beam, which are assembled in a gate shape at the entrance and exit of a construction site or the like. As is apparent from FIG. 2, a hanger rail 3 is attached to the lower side of the beam 2 and a plurality of hangers 4 are slidably suspended. Mounting iron plates 5 are attached to these hangers 4, and the end portions of these iron plates 5 are connected to each other and can be folded at the connecting portions. An upper end of a bar member 6 made of steel bar or the like is attached to the connecting portion of the iron plate 5.

A sheet 7 is stretched over the rods 6, and a sheet notch portion 7a between the rods 6 is provided with a die cut 8 as shown in an enlarged view in FIG. 9 is formed, and the dotted line portion 9a connected to the upper side is folded back to the upper side,
As shown in FIG. 4, the slit 11 can be formed by stopping the surface fastener 10 or the like. The slit 11 has a width of about 10 cm and is formed in a horizontally long shape between the bar members 6 on both sides.

Further, so-called edging portions 7b and 9b, in which threads are entwined and reinforced, are provided in the blindfold cloth portion 9 and the cut edge portion of the sheet 7.

Further, a metal plate or a thick cloth is attached to the edging portion 9b at the lower end edge of the blindfolded portion 9 to make it slightly heavy, and the blindfolded cloth portion 9 is blown away by a slight wind to facilitate the slit 11. It never opens.

[Effects of the Invention] Next, the effects of the present invention will be listed.

(1) Since the blind part is provided in the sheet tension part and the slit is not provided in the attachment part to the bar material, not only can the seat be securely and completely attached to the bar material, but the bar material is always attached by the sheet. As it is hidden, it does not look unsightly.

(2) A slit and a blind cloth portion are formed at the same time by an extremely simple method of making a notch in the sheet itself, and the blind cloth portion blows against the wind from any side of the sheet. Pressed to open the slit.

(3) Since the trimmed portion is provided with the edging portion around which the thread is entangled, the periphery is reinforced and the appearance is excellent.

(4) A metal plate or thick cloth is attached to the lower end of the blindfolded cloth to make it heavy so that the inside cannot be seen even with some wind.
