Description

[Detailed Description of the Invention] [Object of the Invention] Industrial field of application The present invention relates to a handle of a telescopic long door which is used as a gate, a fence or the like at a temporary construction site such as a civil engineering construction site or a construction site.

Conventional technology Conventionally, telescopic long doors used in temporary construction sites such as construction sites and construction sites are easy to fold, lightweight, and useful for transportation, so many long doors can be loaded or stored in transport vehicles. When it is stored in a cabinet, it is compact, does not require space, and can be organized.

However, since the handles fixed to both sides of the center of the traveling rod in such a long door project outward from the traveling rod,
When stacking a large number of long doors or arranging them in parallel, there is a drawback in that the handles of adjacent long doors interfere with each other and stacking without rattling or parallel arranging without gaps cannot be performed.

The problem to be solved by the invention is to make the handle attached to the traveling rod of the telescopic long door foldable so that when the long door is opened and closed, it is projected forward of the traveling rod, and when not in use, it is folded along the long door. When transporting or storing a large number of long doors, the handles of the adjacent long doors do not interfere with each other, and the handle of the extendable long door is provided so that it can be neatly arranged.

[Constitution of device]

Means for Solving the Problems In order to solve the above-mentioned drawbacks, the present invention does not function as a handle by simply providing the handle on the traveling rod of the long door so that the handle wobbles left and right during use. Therefore, a shaft support part having upper and lower communication holes is fixed at the center of both sides of the traveling rod, and a vertical groove continuous with the lower communication hole is formed on the front face of the lower shaft support part. A pivot that extends vertically above and below the handle is pivotally attached to the communication hole of the handle so that it can be slid up and down when the long door is opened and closed. By fitting in the vertical groove, the rotation of the handle in the left-right direction is restricted.

Operation When the long door is opened / closed, the handle is rotated to the position protruding toward the front of the traveling rod, and the pivot is slid downward to fit the lower part of the handle into the vertical groove. Rotation is restricted.

When the long door is not used, the pivot of the handle is slid upward and rotated along the front surface of the long door.

Embodiment An embodiment of the present invention will now be described with reference to the drawings. 1 is a grid rod 3 formed in front and rear two stages pivotally connected by pivots 2, 2a ... And both end portions of the grid rod 3. It is a long door body composed of a running rod 4 and a fixed rod 5 which are slidably clamped.

The rods 3 are rods arranged at equal intervals between the front part and the rear part.
The rods 3a, 3c ... And the rods 3d, 3d ... Are crossed in an oblique manner, and at the crossing portions, they are pivotally attached to each other by pivots 2, 2a.

The traveling rod 4 is provided at its lower end with a roller receiver 6 which is rotatable in the horizontal direction, and a roller 7 is attached to the roller receiver 6.

Reference numerals 8 are handles attached to both sides of the traveling rod 4.
Is a shaft in which a base body 9 is formed in a substantially U-shape, and its ends are vertically symmetrically extended to form pivot shafts 10 and 10a, and the pivot shafts 10 and 10a are fixed to the center of the traveling rod 4 at predetermined vertical intervals. It is pivotally attached to the supporting portions 11 and 11a so as to be vertically slidable.

The shaft support portion 11 is formed in a substantially tubular shape slightly larger than the pivot shaft 10, and upper and lower openings thereof are formed as communication holes 12 and 12a, respectively.
A pivot 10 above the handle 8 is pivotally supported by 2 and 12a.

The shaft support 11a is formed in a substantially U-shaped cross section, and its upper and lower surfaces 13, 1
Communication holes 14, 14a are provided at the center of 3a, the upper communication hole 14 is made vertically long, and a vertical groove 15 is continuously formed from the communication hole 14 to reach approximately half of the front surface 13b of the shaft support portion 11a. Handles 8 in holes 14 and 14a
Axis 10a below is pivotally supported.

The fixed rod 5 has hinges 16 and 16a fixed to its side wall, and is rotatably attached to the pillar 17 standingly fixed to the ground to support the long door body 1 by the hinges 16 and 16a.

Next, the operation of the handle of the telescopic long door according to the present invention will be described. When the long door body 1 is opened and closed, the handle 8 is rotated to a position projecting forward of the traveling rod 4, and the pivots 10 and 10a are slid downward. Then, the lower end portion 18 of the handle 8 is fitted into the vertical groove 15, whereby the lateral movement of the handle 8 is restricted.

Also, when the long door body 1 is not used, the pivot 10 of the handle 8
10a is slid upward and rotated along the front surface of the long door body 1, and the lower end portion 18 of the handle 8 is attached to the upper surface 13 of the shaft support portion 11a.
Is placed.

[Effect of device]

In essence, the present invention is a rod 3 with a two-stage front and rear structure that is pivotally connected.
In a telescopic long door in which both ends of a grid-like rod 3 made up of a, 3b ... Are slidably sandwiched by a traveling rod 4 and a fixed rod 5, a vertical predetermined interval is provided at the center of both sides of the traveling rod 4 to communicate vertically. The shaft supporting portions 11 and 11a having the holes 12, 12a, 14 and 14a are fixed, and the front surface 13b of the lower shaft supporting portion 11a is provided with a vertical groove 15 continuous with the upper communicating hole 14 so that the shaft supporting portions 11 and 11a are Communication hole 1
Since the pivot shafts 10 and 10a formed to extend vertically above and below 2 and 12a, 14 and 14a are pivotally mounted so as to be slidable in the vertical direction, when the long door main body 1 is opened and closed, the handle 8 is rotated to a position projecting to the front of the traveling rod 4. In addition, by sliding the pivots 10 and 10a downward to fit the lower part of the handle 8 into the vertical groove 15, the lateral movement of the handle 8 can be restricted, and the handle wobbles left and right during use. Instead, it can serve as the handle 8.

When the long door body 1 is not in use, the pivots 10,1 of the handle 8 are
Since 0a can be slid upward and rotated along the front surface of the long door body 1 to be in a folded state, when transporting or storing a large number of long door bodies 1,
The handles 8 of the adjacent long door bodies 1 do not interfere with each other, stacking without rattling and parallel tidying without gaps, and the long door bodies 1 can be stored more compactly than ever before, which is a great practical effect. .
