Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a downwardly foldable wind and snow fence unit that can be lowered and automatically folded when not in use.

[Prior art]

When the wind and snow fence is not in use, if the multiple wind and snow boards between the posts are moved upwards and stored, the stored wind and snow boards will obstruct the landscape.
It is preferable to store all the wind and snow break plates in the lower part.

Conventionally, as a wind and snow fence that can store all the wind and snow break boards downward when not in use, as published in Publication No. 17931/1987, a wind and snow break fence that can store all the wind and snow break boards downwards has a A rotating rod that extends in the left and right direction is fixed, and both ends of the rotating rod are fitted into the grooves of the column so that they can move up and down and rotate. A structure in which the upper and lower parts are held at a specified level by two bolts inserted through the pillars, and each wind and snow board is connected by an interlocking member that is detachably attached to them, and a weight is attached to the interlocking member. is known for its wind and snow fence.

[Problem that the invention seeks to solve]

However, in the case of the above-mentioned conventional wind and snow break fence, when each wind and snow break board is stowed downward when not in use, the connection between each wind and snow board and the interlocking member is released, and the large numbers on both the upper and lower sides of each rotating rod are removed. bolts must be removed from the posts, and if each wind and snow board is to be set in place when the wind and snow fence is in use, attach the end of the rotary rod attached to each wind and snow board to each post. On the other hand, it is necessary to hold it with two bolts, upper and lower, and to connect each wind and snow board and the interlocking member detachably.
Therefore, when storing and assembling all the wind and snow protection plates below, it is necessary to perform attachment and detachment operations many times, which poses a problem that the storage and assembly operations become complicated and take a long time.

is inserted through the bolt locking fitting 45, and a fixing nut 48 that engages with the lower surface of the bolt locking fitting 45 is screwed onto the hook bolt 47.

When folding the wind and snow fence downward, first
As shown in Figure 0, the main body 50 of the lever swing type traction machine (product name: Lever Block) 49 is
An end of a load chain 53 that is locked to a locking pin 51 provided on the front vertical frame 13 of the column holding member 11 via a connecting tool 52 such as a connecting chain with a hook, and is extended from the main body 50. The hook 54 attached to the hook bolt 4
After engaging the engagement ring portion 43 of the elevating strip 9 removed from the lifting member 7, the load chain 53 is tensioned.

Next, remove the bolts 10 and remove the end frame members 1 and 4.
After disassociating the lever from the support 7, the lever swinging type traction machine 49 is returned to operation, and the lower wind and snow barrier unit 3 and the upper wind and snow barrier unit 6 are moved downward. When the lower end of the end frame member 1 of the lower wind and snow fence unit 3 hits the sliding guide plate 18 at the upper end of the rear vertical frame 14, the lower end of the end frame member 1 moves rearward due to the guiding action of the slip guide plate 18. Then, the lower part of the end frame member 1 moves downward along the rear part of the rear vertical frame 14 and abuts against the wind and snow fence unit pedestal 12.

When the lever swing type traction machine 49 is further operated back, the lower wind and snow break fence unit 3 and the upper wind and snow break fence unit 6 are folded, and then, as shown in FIG. Wind and snow fence unit pedestal 1 with frame member 1 in horizontal position
2, and the upper wind and snow fence unit 6
The end frame member 4 is placed on the end frame member 1 in a horizontal state.

Next, as shown in FIG. 12 to FIG.
After removing the lower end of the column 7 and the column holding member 11, rotate the column 7 around the pivot 27.
are rotated horizontally, and the connecting plate 34 of one of the adjacent columns 7 and the web 33 of the other column 7 are overlapped and connected by bolts 56.

When assembling the wind and snow fence, the posts 7 are erected, the posts 7 and the post holding members 11 are fixed with the bolts 28, and the hook bolts 55 are removed, and the fence is pulled out from the main body 50 as shown in FIG. The hook 54 at the end of the load chain 53
is engaged with the engagement ring portion 43 of the elevating strip 9.

Next, the lever swinging type traction machine 49 is towed and operated to lift the upper wind and snow fence unit 6 and the lower wind and snow fence unit 3 one after another until the upper end of the end frame member 4 hits the stopper 44. After stopping the traction operation of the lever swing type traction machine 49, and then fixing the end frame members 1 and 4 to the support column 7 with the bolts 10, the lever swing type traction machine 49 is removed, and then the lifting The engaging ring portion 43 at the hanging end of the body 9 is locked to the bolt locking fitting 45 via the hook bolt 47 and the fixing nut 48.

When carrying out the present invention, the structure may be such that only the wind and snow fence units 3 and 6 are folded without folding the struts 7.

〔Effect of the invention〕

According to this invention, when the bolts 10 connecting the end frame members 1, 4 and the support columns 7 are removed, the lower wind and snow fence unit 3 and the upper wind and snow fence unit 6 can be moved simply by the lifting strips 9. By lifting and lowering the wind and snow fence units 3 and 6, the wind and snow fence units 3 and 6 can be automatically and quickly folded and placed on the wind and snow fence unit pedestal 12, and when assembling the wind and snow fence. By simply pulling the lifting strip 9, each wind and snow fence unit 3, 6 can be automatically and quickly unfolded and lifted. After hoisting it to a predetermined height, simply attach each wind and snow fence unit 3, 6.
Attach the end frame members 1 and 4 to the support column 7 with the bolt 1.
0, the plurality of wind and snow break plates 2, 5 arranged across the left and right columns 7 can be easily and quickly attached with a small number of bolts 10, and the lower part of the integral structure with each column 7 can be easily and quickly attached. Since the wind and snow protection fence unit 3 and the upper wind and snow protection fence unit 6 are connected by bolts 10, the rigidity of the wind and snow protection fence in the left and right direction can be increased, and furthermore, the downward folding type wind and snow protection fence of the present invention Since the structure is simple, it can be manufactured at low cost.
