Description

  The present invention relates to a handrail antifouling cover for a work platform of an aerial work platform or an aerial work platform, particularly a platform type work floor.

  Conventionally, when painting ceiling surfaces or wall surfaces on the work floor of an aerial work platform or an aerial work platform, excess paint droplets on the brush or roller brush can contaminate the work floor, especially the platform railing and floor. There were many. In this case, the floor surface can be easily prevented from being soiled by laying a curing sheet for painting, but it is not only troublesome to cover the handrail with the curing sheet, but the curing sheet is usually made of polyethylene. Because there are many, there is no air permeability, and if it is surrounded by a curing sheet, the work vehicle and the work table may be greatly shaken due to a cross wind, and there is a risk that the worker may fall. Further, the polyethylene curing sheet was not satisfactory in terms of the adsorptivity of the paint.

  Therefore, there is a need for a protective cover that can be easily attached and detached by an operator, has little influence on a work vehicle or a work table even when subjected to crosswinds, and is inexpensive enough to be disposable like a curing sheet. It was.

  In order to solve the above-mentioned problems, the working floor handrail antifouling cover according to the present invention is a handrail antifouling cover for an aerial work platform or an aerial work platform work floor, and includes an upper handrail and a floor for the work floor. An antifouling cover main body covered with a sheet having air permeability, and an upper peripheral edge mounting portion for fixing the upper opening peripheral edge of the antifouling cover main body so as to cover the upper handrail upper part. Further, the present invention is characterized in that a lower end contraction part is provided for allowing the lower opening of the antifouling cover main body to wrap around the bottom of the work floor.

  Further, the present invention is characterized in that at least one longitudinal ridge is provided at least at one side of each side surface of the antifouling cover main body.

  Further, the present invention is characterized in that a non-woven fabric that is relatively inexpensive and easy to process is used as the sheet having air permeability.

  According to the present invention, when performing painting work on a platform such as an aerial work platform, it is possible for an operator to install the work floor handrail antifouling cover according to the present invention alone. Efficient work is possible without care. In addition, the handrail antifouling cover for work floors according to the present invention is obtained by processing a sheet having a breathable antifouling cover body, so that there is relatively little shaking of the work floor even when subjected to crosswinds during work. The worker can concentrate on the work. In addition, by attaching the work rail handrail prevention cover for the work floor according to the present invention, there is no risk of being charged a high cleaning cost by a rental company of an aerial work vehicle as in the past, and it is inexpensive when the cover becomes dirty. All you need is a replacement fee.

  Furthermore, the handrail antifouling cover for work floors according to the present invention is provided with at least one vertical hook on each side of the antifouling cover body, so that even if the width of the platform is slightly different, It can be mounted and can be used to some extent with telescopic platforms.

FIG. 1 is a perspective view showing a platform and a lift arm portion of a scissor type aerial work platform. FIG. 2 is a perspective view showing a state in which the work floor handrail antifouling cover according to the present invention is attached to the work floor portion of FIG. FIG. 3 is a view showing a cross section of one side surface in a state where a work floor handrail antifouling cover is attached to the platform handrail. FIG. 4 is a plan view showing an example in which the periphery of the upper opening of the handrail antifouling cover for work floor is fixed to the handrail support with a rubber string.

  Hereinafter, a work floor handrail antifouling cover according to the present invention will be described with reference to the drawings.

  FIG. 2 shows a state in which the work floor handrail antifouling cover 2 according to claim 2 is attached to the platform type work floor 1 of the scissor type aerial work vehicle shown in FIG. The same applies to an aerial work platform.

  In this embodiment, the anti-smudge cover main body 21 of the handrail anti-smudge cover 2 for the work floor is a long non-woven fabric that is approximately 20 cm wider than the height of the upper handrail 11 of a specific platform, and is formed on the upper handrail and each side of the floor. The side surfaces to be sandwiched were wrapped around, and both ends were fusion-bonded to form a cylindrical tube with a rectangular cross section when mounted on the platform handrail. You may join with an adhesive agent without fuse | melting.

  In addition, ridges 24 extending in the vertical direction by about 2 centimeters were provided at two locations on each side surface sandwiched between the upper railing and each side of the floor. The number of ridges was about 5 in consideration of sagging. Of course, the number of places where the ridges are provided is not limited to two, and the number of ridges need not be limited to five. It should be determined by the range of the platform to be applied. The heel does not need to be provided up to the upper and lower ends, and the tension is adjusted in the vicinity of the upper and lower ends by the expansion and contraction of the rubber cord.

  The lower opening is folded inward by about 2 centimeters, the end is fused to the main body, and a rubber cord 23 is passed through the lower opening in the folded space. The elastic cord 23 is slightly shorter than the perimeter of the folded state with the heel folded, and is easily extended to the perimeter of the state where the heel is opened. The lower end of the cover is always the floor of the platform. Fits under the surface.

  Further, the upper opening of the handrail antifouling cover 2 for work floors is folded inward by about 2 centimeters like the lower opening, and its end is fused to the main body. However, unlike the lower opening, a vertical cut is provided at the folded portion at a position about 5 centimeters away from the portion covering the upper end of the handrail support 11 at the corner of the platform 4 along the upper side of each handrail. The rubber string 22 is passed along each side, and both ends of the rubber string 22 are extended from this cut part by about several tens of centimeters, and a locking tool 25 is attached to the tip (FIG. 4).

If the rubber cord is too long when mounted on a narrow platform, the rubber cord is wound several times from the outside of the handrail support column to adjust the length, and then connected to the rubber cord on the adjacent side by the locking tool 25.
As described above, the folding of the heel is provided only in the portion corresponding to the height of the side surface of the platform, and the expansion and contraction of the portion that goes around the floor and the handrail is adjusted by the expansion and contraction of the rubber string.

  Nonwoven fabrics are manufactured with various characteristics depending on the material and manufacturing method. In the present invention, it is preferable to use a material having high air permeability and good paint adsorbability. As a specific example, a non-woven fabric of synthetic fibers produced by a production method called a direct spinning type is considered suitable, but is not necessarily limited to such a production method or material.

  Hereinafter, an example of an installation procedure of the handrail antifouling cover 2 for work floor according to the present embodiment will be described.

  First, turn over the handrail fouling cover 2 for the working floor so that the upper opening fits inside the platform upper handrail 11, and the rubber cords 22 drawn from the upper sides of the work floor wrap around the outside of each of the four handrail pillars. In this way, the connection is made with the locking tool 25. Some differences in the size of the platform are accommodated by the expansion and contraction of the rubber string 22, and the tension of the rubber string 22 is adjusted so that the collar 24 of the antifouling cover main body spreads appropriately according to the length of the handrail. Adjustment is preferably performed by turning the rubber cord 22 around the handrail support several times from the outside.

  With the rubber cords 22 wrapping around and connected to the outside of each handrail support column at all four corners, the operator gets into the inside from the platform entrance, folds the cover from the inside to the outside of the handrail, and grabs the lower opening little by little. To complete the installation.

  When considering the prevention of internal fouling of handrails, for example, the pile side of the hook-and-loop fastener is bonded to a plurality of locations on each side of the upper opening of the handrail antifouling cover 2 for work floors of the present invention. Similarly, an inner antifouling cover in which the hook side of the hook-and-loop fastener is bonded may be attached to the corresponding portion of the upper side of the nonwoven fabric cut by the size of the side surface. Of course, a fixing means other than a hook-and-loop fastener may be used for mounting, or the upper side of the inner antifouling cover may be fixed by welding or the like to the part where the work floor handrail antifouling cover hits the upper handrail from the beginning.

  Similarly in these cases, it is preferable to attach the outer antifouling cover 2 first and then attach the inner antifouling cover.

  Since the intermediate bar of the handrail is difficult to see when the inner antifouling cover is attached, it is preferable to use a material having excellent light permeability as well as air permeability as the non-woven fabric used for the inner antifouling cover.
