Description

  The present invention relates to a seat cover that covers an opening of a container that stores waste, and in particular, the opening can be easily opened and closed as necessary without removing the entire seat cover, and the stored matter such as waste is scattered. And a seat cover that prevents rainwater accumulation.

  Conventionally, a steel box container is often used as a container for storing waste. These box-shaped containers are open containers with no lid on the top, or a method of opening and closing a top plate called a wing type above the open container (see Patent Document 2), canopy type (see Patent Document 3), bellows There are slide types. However, when an open container is left outdoors, it is indispensable to cover it to prevent stored items such as waste from being scattered by wind or from getting wet with rainwater. However, the wing type, canopy type, and bellows / sliding type are all expensive because they involve large-scale devices, and many of them have a structure with a wide open lid. There is a drawback that the contents get wet and the contents get wet. Also, in the bellows / slide type, the rail provided on the side surface of the container gets in the way and the input object collides, which is likely to cause a failure. In addition, it has been difficult to fix a sheet that has been covered with a sheet of rubber from the top of the container and the periphery of the sheet is fixed to the side of the container with a rubber strap when the wind is strong. If you place a sheet on an empty container with a small amount of stored items, rainwater accumulates on the sheet and the sheet hangs down, so it takes time to remove the sheet, and rainwater enters the container and the stored item gets wet It was a problem.

  An invention of a seat cover for rain cover of a lidless container in which rain water does not accumulate on the upper surface of the seat is disclosed (see Patent Document 1). However, this invention is intended for containers for carrying large luggage such as decorative steel sheets, and it is assumed that the entire seat cover is removed when the luggage enters and leaves, and it is not possible to open and close part of the seat cover. The technical idea of the present invention is different from the present invention in that it is not assumed.

Registered Utility Model No. 3031751 JP 2002-347883 A JP 2003-341785 A

  In order to solve the above-mentioned problems, the present inventor has intensively studied. As a result, a wire rope cover frame is formed, and a cover member is slidably or detachably attached to the cover frame. The present invention has been conceived by finding that a suitable range of inlets can be easily opened and closed by twisting or rotating the cover frame of the present invention. It is an object of the present invention to provide an improved seat cover that can easily open and close the opening partly as necessary without removing all the cover members, and is provided with a water conduit so that rainwater does not collect.

  In order to solve the above-described problems, the present invention provides a seat cover that covers an opening of a container that stores waste and the like, and is provided on a side wall near an intermediate point of an upper portion of the side wall facing the opening of the container. A plurality of cover members made of a flexible waterproof sheet are provided with a pair of wire rope cover frames surrounding the opening of the container so as to be pivotally connected to the locking shaft. The cover frame can be slidable and / or detachably attached to the cover frame via the locking tool, and the cover member can be covered with the upper part of the container, and the peripheral end of the cover member can be locked to the container side wall. It is set as the seat cover characterized by the above-mentioned (Claim 1).

  Further, in order to solve the above-mentioned problems, the present invention provides the seat cover, wherein the wire rope cover frame is a region excluding a region near both ends or a region near both ends and a center of a U-shaped vertical side. Preferably, the seat cover is formed by covering a region excluding the region with any one of a hard metal pipe, a hard resin pipe, or a hard synthetic resin (Claim 2).

  In order to solve the above problems, the present invention provides the seat cover with a through hole in an intermediate portion of the cover member surrounded by each cover frame and penetrating one end of the water conduit from the back side of the cover. Preferably, the seat cover is connected to the hole and the other end of the water guide pipe is guided to the outside of the container, and rainwater collected on the surface of the cover is discharged to the outside through the water guide pipe.

  In the seat cover according to the present invention, as described above, the wire rope cover frame is rotatably connected to the locking shaft, and the cover member is slidably or detachably locked to the cover frame. Therefore, the opening and closing work of the partial opening can be performed smoothly. That is, in the case of a seat cover without a conventional cover frame, when the seat cover is fixed to the container, the seat cover is blown by the wind. . In the seat cover of the present invention, the cover member is locked to the cover frame, and the opening can be easily opened and closed simply by opening and closing the cover frame without being blown by the wind. After the cover frame is closed, the cover member Since the peripheral elastic string only needs to be locked to the side surface of the container, the operation is easy and the scattering of stored items and the intrusion of rainwater can be minimized. In addition, the wire rope in the exposed portion has a property of maintaining a deformed shape with respect to torsion by partially covering it with a hard cladding tube made of metal or synthetic resin except for the exposed portion in the vicinity of both ends of the wire rope. Therefore, by opening the corner of the cover frame or rotating the cover frame on one side, an opening having a desired width corresponding to the input amount can be obtained. Further, by attaching a water guide pipe to a through hole formed in the middle part of the cover surrounded by the cover frame and extending the water guide pipe outside the container, there is an effect of preventing rain water from accumulating on the upper surface of the cover. Further, by using the seat cover of the present invention, it is possible to prevent the intrusion of rainwater, so that waste of energy required for transportation and waste disposal can be reduced, and the generation amount of carbon dioxide gas can be reduced.

A cover member 19 made of a flexible waterproof sheet is slidably or detachably attached to the cover frames 20L and 20R via a plurality of locking members 17, and covers the cover member 19 over the container upper portion. A plurality of elastic cords 18 provided at the peripheral end portion of the cover member 19 are hung on the hooks 22 on the container side wall portion to lock the cover member 19.

  Although the container used for this Embodiment is not specifically limited, The case where it applies to a general purpose steel box container is demonstrated. The side wall 13 of the container 11 has a structure in which a steel plate is stretched inside a frame in which vertical and horizontal beam members 14 are combined, and means for providing the shaft stop plate 15 on the horizontal beam member 14 above the side wall 13 is not particularly limited. The pair of shaft stopper plates 15 and 15 are preferably fixed to the horizontal beam member 14 with bolts and nuts so as to sandwich the horizontal beam member 14 from both sides. A locking shaft 16 is fixed inside the pair of shaft stop plates 15 and 15 with bolts and nuts or the like.

  Next, the cover frames 20L and 20R are formed by bending a steel wire rope into a U-shape and attaching steel fasteners to the locking shafts 16F and 16B at both ends thereof (connecting a fastener to the wire rope). Bracket) is fixed. The steel wire rope is obtained by twisting a plurality of steel wires, and the material and thickness are not particularly limited as long as they have a certain degree of rigidity, but those having a diameter of about 5 to 20 mm are preferable. . In addition, the portions other than the exposed portion 28 of the steel wire rope in the vicinity of both ends of the folded cover frame and in the vicinity of the center of the U-shaped vertical side are made of a steel wire rope made of a metal pipe such as iron or a hard resin. It is preferred to coat through a pipe made. Since the shape retaining property is maintained by the pipe, when one corner of the cover frame is lifted, the wire rope of the exposed portion 28 is deformed by bending or twisting, but the arm portion including the corner portion passed through the pipe is shaped. Is held, so that a partial opening is easily formed. Moreover, it is preferable also from the point of grip property, safety, and appearance. When a wire rope having a small rigidity of 10 mm or less is used, the shape of the cover frame is held by the pipe, which is particularly preferable. Instead of the metal pipe or the hard resin pipe, the wire rope is a so-called coated wire rope in which a hard thermoplastic resin such as polyolefin resin, vinyl chloride resin, polyamide resin or the like is melt-coated, and the exposed portion What notched 28 may be used. The shape of the cover frame is not particularly limited, but it may be formed substantially along the side wall edge so that the entire container opening is covered when the cover frame is connected to the locking shaft and placed on the side wall edges on both sides. preferable.

  The flexible waterproof sheet constituting the cover member 19 is not particularly limited as long as it is waterproof in addition to the currently widely used materials such as tarpaulin.

Examples of the flexible synthetic resin include polyolefin resins such as medium and low density polyethylene, ethylene / propylene copolymer (EPM), Various elastomers such as ethylene / propylene / diene copolymer (EPDM), vinyl chloride resins, and other thermoplastic resins, particularly soft vinyl chloride resins are preferred because of their excellent welder processability and good handling.

  A plurality of locking tools 17 for locking the cover member to the cover frame are attached to positions on the back surface of the cover member 19 that are in contact with the cover frames 20L and 20R. The locking device is not limited as long as the cover is slidably or detachably attached to the cover frame. For example, a split annular locking device made of thermoplastic resin is heat-sealed to the cover, and this The cover frame can be pushed into the ring of the annular locking tool to be slidably and / or detachably locked. In addition to the split ring-shaped locking tool, any means can be adopted as long as it can be slidably or / and detachably locked, such as a cloth string or a rubber string.

  For example, an eyelet member is provided at the peripheral end portion of the cover member 19, and an elastic string is passed through the eyelet member, or a gusset is inserted in the peripheral end portion of the cover so as to correspond to a hook on the container side wall portion. An elastic string is provided at a position to be engaged, and the elastic string is hung on the hook to lock the cover to the container side wall. In addition to the locking means, any means can be adopted as long as it has a similar locking function.

  To open the upper part of the container, the elastic string on the opening side is removed from the hook in advance. Next, when the corner of the cover frame is lifted, the wire rope at the corner that hits the locking shaft of the cover frame and the tip of the diagonal is twisted, and the corner of the container opens in a triangular shape, and is held in the open state. (See FIG. 1). Further, if one of the cover frames is tilted to the opposite cover frame side, one side of the container opens (see FIG. 2). If the cover member is brought close to the front end side of each cover frame in this state, a range close to almost the entire opening can be opened (see FIG. 3). When closing, the cover frame is returned to the original position, and the elastic string is locked to the hook on the container side wall.
