DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a telescopic gate having a vertical pantograph telescopic mechanism, and in particular, fixes one side of a door to a gate post or the like without using wheels, casters, etc. below the door. The present invention relates to a so-called hanger-type telescopic gate fixed to the section.

[0002]

2. Description of the Related Art This type of telescopic gate is widely used because it does not require any special work in the passage and can save labor during the work. However, the conventionally known hanger-type telescopic gates have a structure in which the inclined members that are inclined at the same angle in opposite directions are joined by pins at intersections. Are also provided at equal intervals, so if the door is extended,
Due to the weight of the door body, its moving end hangs down from the horizontal state, making it difficult to increase the opening width of the door body.If the door body becomes longer, it is necessary to attach wheels and casters to the lower part of the door body. . Japanese Utility Model Publication No. 6-24558 discloses that in such a telescopic gate, the distance between the upper and lower pin axes of the oblique material at the upper part of the door body is made larger than the distance between the upper and lower pin axes of the oblique material at the lower part of the door body. In addition, there is disclosed a device in which the intermediate portion of the door body is deformed upward to omit the casters at the intermediate lower portion of the door body.

[0003]

In a telescopic gate called a hanger type, the distance between the upper and lower pin axes of the oblique member at the upper part of the door body is determined by the distance between the upper and lower pin axes of the oblique member at the lower part of the door body. By reducing the size of the door, it is possible to match the splash at the moving-side end of the elongated door body with the droop due to its own weight, thereby preventing the elongated door body from sagging. However, when such a slanted material is suspended on a vertical fixed gate post or the like with a door body having a changed distance between the upper and lower pin axes, and the extended door body is supported in a horizontal state, the moving side frame of the door body is vertically moved. Since the movable side frame of the door body abuts against a door post or the like locally, the door cannot be completely locked.

[0004]

Means for Solving the Problems The inventors of the present invention have made intensive studies in view of such circumstances, and as a result, the crossing positions of the front and rear oblique members inclined in opposite directions are pin-connected, and one side thereof is provided. A fixed side frame, a movable side frame is provided on the other side, and one pin shaft for pivotally attaching the oblique material to each of the fixed side frame and the movable side frame is fixed,
And a door body in which other pin shafts at the upper and lower positions are vertically slidably fitted to guide members of the fixed side frame and the movable side frame,
In a telescopic gate where the fixed side frame of the door body is suspended from the hanging former gate post, and the moving side frame of the door body is detachably engaged with the door stop gate post, etc., the up and down of the oblique material in the upper part of the door body The distance between the pin axes is made smaller than the distance between the upper and lower pin axes of the oblique material at the lower part of the door body, and the guide member of the moving frame is formed in a strip shape, and its end is rotatably connected to the moving frame to extend. The intended purpose is achieved by bringing the movable frame of the door body into contact with a door stop gate post or the like and integrally fixing the strip-shaped guide member to the movable frame.

Further, according to the present invention, in the telescopic gate having the above structure, one end of a strip-shaped guide member is rotatably connected to the movable side frame, and a support shaft provided at the other end of the strip-shaped guide member is connected to the movable side. Slidably fits into the elongated groove formed in the frame,
In the state where the extended door body is brought into contact with the movable side frame and the door stop post, etc., the strip-shaped guide member and the movable side frame are integrally formed at the position where the support shaft and the horizontally long groove of the movable side frame are fitted. By establishing it, a practical telescopic gate was completed.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS A telescopic gate suitable for carrying out the present invention has a fixed side frame on one side and a movable side frame on the other side by connecting the crossing positions of front and rear oblique members inclined in opposite directions with pins. , One pin shaft for pivotally attaching the oblique member to each of the fixed side frame and the moving side frame is fixed, and the other pin shaft in the up and down position is vertically slid on the guide members of the fixed side frame and the moving side frame. A door is formed by freely fitting, and a vertical lattice is typically provided at the intersection of the front and rear oblique members as shown in the drawing. It can be a bamboo and arrow-shaped thing consisting only of lumber.

[0007] Usually, the height of this type of telescopic gate is from 1 m to
The front and rear oblique members intersect at 5 to 7 places from the upper end to the lower end, and the intersecting positions are rotatably connected by a pin shaft. In the present invention, the distance between the pin axes of the oblique members in the upper part of the door body is smaller than the distance between the pin axes of the oblique members in the lower part of the door body, but the difference is from 0.5 mm. A range of 1 cm is appropriate. Further, in this case, the present invention can be carried out without changing the distance between the pin axes of the oblique members from the upper end to the lower end of the door body in proportion.

In the telescopic gate of the present invention, the distance between the pin axes of the oblique member at the upper part of the door body is made smaller than the distance between the pin axes of the oblique member at the lower part of the door body. When a vertical load (self-weight) is not applied to the door body in the state, the door body becomes an inverted fan shape as shown in FIG. Although, theoretically, the moving end of the door body is in a warped state,
The door body descends due to the clearance of the pin connecting portion and the weight of the constituent members, and the extended door body can be in a substantially horizontal state. However, when the door body in which the distance between the upper and lower pin axes of the oblique material is changed is suspended on a vertical fixed gate post or the like, and the elongated door body is supported in a horizontal state,
The movable side frame of the door body cannot be positioned vertically, and the movable side frame of the door body cannot be entirely brought into contact with the door stop gate post or the like. .

According to the present invention, a strip-shaped guide member is used for the movable side frame of such a telescopic gate, which is slightly longer than the distance that the pin shaft moves up and down by opening and closing the door, and has a vertically elongated slide groove formed inside. , One end thereof is rotatably fixed to the moving side frame, and the moving side frame of the extended door body is brought into contact with the door stop gate post, and the other end of the strip-shaped guide member is moved to the moving side frame. Thus, the door stop door pillar and the moving side frame of the door body are improved so that they come into full contact with each other.
To attach the strip guide member to the moving frame, a horizontally elongated groove is formed in the moving frame, one end of the strip guide member is rotatably connected to the moving frame, and the screw is planted at the other end. The sliding shaft is slidably fitted in the horizontally long groove, and the moving side frame of the extended door body is brought into full contact with the door post gate post, and the shaft and the horizontally long groove are strongly fitted at this fitting position. All you have to do is screw it. According to this structure, if a problem occurs in contact between the movable side frame of the elongated door body and the door stop gate post or the like in the use of the gate, the screw of the support shaft is easily loosened and the door stop angle of the movable side frame. Can be adjusted. The laterally long groove formed in the movable side frame should theoretically be curved, but may be linear. According to the gist of the present invention, it is also possible to provide a support shaft on the movable side frame, form a horizontally long groove at the end of the strip-shaped guide member, and fit the support shaft of the movable side frame into this for fixing. It is. Hereinafter, the present invention will be described specifically with reference to Examples.
