Description

  The present invention relates to a cargo bed cover, and more particularly to a cargo bed cover that covers an opening of a box-shaped cargo bed that can accommodate a load.

  Conventionally, a cargo bed cover shown in Patent Document 1 is disclosed as a cargo bed cover that covers an opening of a cargo bed that accommodates luggage. In the handcart, the cargo bed cover is configured by a seat body that covers an opening of a cargo bed that accommodates luggage, and a holder that attaches the seat body to the cargo bed. The seat body is provided with a cylindrical central bag portion penetrating in the left-right direction at the center portion in the front-rear direction, and the center bag portion is fixed to the cargo bed by causing a holder to penetrate the circumference of the cargo bed. . Further, the seat body has a cylindrical front peripheral bag portion along the peripheral edge portion of the seat body in front of the central bag portion, and a cylindrical rear periphery along the peripheral edge portion of the seat body in the rear of the central bag portion. Each bag part is provided, and a string-like front elastic body having elasticity is passed through the central bag part and the front peripheral bag part to form an annular shape shorter than the peripheral length of the front half part of the opening, and the central bag part and The front peripheral bag portion is formed outside the peripheral wall of the front half portion and the rear half portion of the opening portion by penetrating a string-like rear elastic body in the rear peripheral bag portion so as to be shorter than the peripheral length of the rear half portion of the opening portion. And it is the structure which covers each half of the whole opening part of a loading platform by hanging a back periphery bag part. According to this cargo bed cover, only one half of the opening is lifted up by hand so as to peel off the front half and the latter half of the seat body hung on the opening by the expansion and contraction of the front elastic body or the rear elastic body. With the seat covered in the seat body, the other half is opened to allow loading and unloading from the front and rear half of the loading platform.

  However, for example, when the rear half part is opened in a state where the front half part of the opening part of the cargo bed is covered, the rear half part of the seat body gathers in a state of being brought close to the central bag part side by contraction of the rear elastic body. Will be allowed to. The sheet main bodies gathered in the gathering state in this manner flutter by the wind or fall into the storage space of the cargo bed by the flapping. When the luggage accommodated in the loading platform has fluidity such as concrete or liquid, if the sheet main body falls into the accommodation space, the luggage adheres to the sheet main body and is damaged. In addition, since the sheet body is divided into half parts with respect to the opening, the size of the opening that can be opened is limited, and the opening cannot be opened by a desired size. There was a problem of being bad.

  Therefore, an object of the present invention is to provide a cargo bed cover that can open the opening in a desired size without bringing the sheet covering the opening into a squeezed state.

As a configuration of the loading platform cover for solving the above problem, a loading platform cover including a sheet that covers an opening of a loading platform having an accommodation space, and a biasing force in a direction in which the sheet is wound in a state where the sheet is unwound The resulting winding shaft, a fixing tool that supports the winding shaft and that is detachably provided at the periphery of the opening, and a sheet that is provided at the front end of the sheet and that keeps the sheet closed against the urging force It was set as the structure provided with a fixing tool.
According to this configuration, the take-up shaft supported by the fixture fixed to the loading platform is urged in the sheet take-up direction by the urging means, so that the take-up shaft is unwound from the take-up shaft by the urging force. Since the rolled sheet can be wound around the winding shaft, the sheet can be prevented from sagging when the position of the front end of the sheet in the opening is moved. In other words, when the front end of the sheet is moved in the direction of the take-up shaft so as to release the closed state of the opening by the sheet and is fixed to the loading platform by the sheet fixing tool, the opening of the loading platform is not brought into the holding state. Can be opened in a desired size.
Moreover, as a structure of the loading platform cover for solving the said subject, it was set as the structure by which the sheet fixing tool was tinged with magnetic force.
According to this configuration, since the sheet fixing tool is magnetic, it is adsorbed to the cargo bed by the magnetic force of the sheet fixing tool, so that the front end side of the sheet is easily fixed at an arbitrary position with respect to the opening of the cargo bed. be able to.

In addition, 2 A of opening parts of the loading platform 2 in this embodiment are substantially rectangular shapes as shown in FIG.

  In this handcart 1, luggage is accommodated in the accommodation space of the loading platform 2 from above the loading platform 2 through the opening 2 </ b> A. Then, the operator lifts up the two handles 4 extending from the handcart 1 by hand, and pushes the handle 4 forward with the support legs 3B at the rear of the loading platform 2 lifted from the road surface, thereby moving the wheels 3A. By rolling, it becomes possible to carry the load loaded on the loading platform 2.

With reference to FIG. 1 and FIG. 2, one Embodiment of the luggage carrier cover 6 is described.
The loading platform cover 6 includes a shaft-side fixture 11 for fixing the main body of the loading platform cover 6 to the handcart 1, a winding shaft 12 rotatably supported by the shaft-side fixture 11, and a shaft-side fixture. 11 and the winding shaft 12, a biasing means that applies a biasing force to the winding shaft 12, a sheet 14 that is wound around the winding shaft 12, and a front end portion of the sheet 14 that is attached to the winding shaft 12. A seat fixing tool 15 for fixing the front end side of the seat 14 to the handcart 1 is provided.

The shaft side fixing tool 11 includes a bead fixing portion 16 for fixing the shaft side fixing device 11 to the bead 5 and a shaft fixing portion 17 for supporting a winding shaft 12 described later.
The bead fixing portion 16 is composed of a flat plate-like upper piece 16A, vertical piece 16B, and lower piece 16C having a predetermined thickness, and is U-shaped so as to surround the bead 5 formed at the peripheral portion of the opening 2A of the handcart 1. Formed. The bead fixing portion 16 makes the upper piece 16A abut on the upper surface side of the bead 5 and extends in a direction opposite to the upper piece 16A from the lower end of the vertical piece 16B extending downward from one end side of the upper piece 16A. The bead 5 is formed so as to surround the lower piece 16C. The lower piece 16C includes a screw hole 18 penetrating in the plate thickness direction. A screw 19 for fixing the shaft side fixing tool 11 to the bead 5 is screwed into the screw hole 18 from below.

A shaft fixing portion 17 is formed behind the vertical piece 16B of the bead fixing portion 16. The shaft fixing portion 17 is a flat plate piece that is continuous with the vertical piece 16B so as to extend rearward of the vertical piece 16B and projects upward from the upper piece 16A. A shaft fixing hole 20 for fixing the support shaft 13 is formed in a portion extending above the upper piece 16A of the shaft fixing portion 17, in other words, above the opening 2A of the bead 5.
The shaft fixing hole 20 is a circular hole that penetrates in the thickness direction and has a notch 20A in part. A support shaft 13 for supporting the take-up shaft 12 that winds up the sheet 14 is fitted into the shaft fixing hole 20. The shaft fixing hole 20 is preferably opened in the bead fixing portion 16 as follows, for example. Specifically, the position of the lower end 12z of the outer peripheral surface 12a of the winding shaft 12 supported by the support shaft 13 fixed to the shaft fixing hole 20 is positioned below the upper end 5z of the bead 5 of the loading platform 2. (See FIG. 3A). By setting the position of the shaft fixing hole 20 in the bead fixing portion 16 in this way, the sheet 14 fed out from the take-up shaft 12 can be brought into contact with the rear end of the bead 5, so that the entire area of the opening 2 </ b> A is covered. It is possible to reliably close with the sheet 14.

As described above, the shaft side fixing tool 11 is detachably fixed to the loading platform 2 by sandwiching the bead 5 between the upper piece 16A of the bead fixing portion 16 and the screw 19 (see FIG. 4). The shaft-side fixture 11 is provided to face the left and right beads 5 extending in the front-rear direction so that the shaft-fixing portion 17 projects rearward from the rear portion of the opening 2A.
In addition, the shaft side fixing tool 11 is comprised with a metal, resin, etc., for example. Further, by using a screw 19 that can be directly tightened and tightened, such as a thumbscrew or a screw with a knob, it is easy to attach the shaft-side fixture 11 to the bead 5 or to change the mounting position. .

FIGS. 3A and 3B are a cross-sectional view and a plan view of the support shaft 13 interposed between the shaft-side fixture 11 and the winding shaft 12.
As shown in FIGS. 3A and 3B, the support shaft 13 includes a fixed drum 21, a rotating drum 22, and a spring 23. The fixed drum 21 is a cylindrical shaft body, and includes a fitting portion 25 that fits into the shaft fixing hole 20 of the shaft fixing portion 17, and a screw hole 26 that is formed on an end surface on the side having the fitting portion 25. And a spring accommodating portion 27 that accommodates the spring 23, and an engaging groove 28 formed over the entire circumference along the circumferential direction of the outer peripheral surface.

  The fitting portion 25 includes a notch surface 25 </ b> A that is notched in a planar shape along the axial direction from the end surface on one end side, corresponding to the shape of the shaft fixing hole 20 on one end side of the fixed drum 21. A bottomed screw hole 26 extending in the axial direction is formed on the end surface on the side where the fitting portion 25 is formed at a position corresponding to the axial center of the fixed drum 21.

The spring accommodating portion 27 is formed as a cylindrical recess that can accommodate the spring 23 on the other end side of the fixed drum 21. The recess is concentric with the axis of the fixed drum 21 and is cylindrically formed along the axis, and a mounting end 23A on one end side of the spring 23 is extended to the bottom surface of the recess in parallel with the axial direction. A locking hole 27A for locking is provided.
The fixed drum 21 of the support shaft 13 has a fitting portion 25 fitted in the shaft fixing hole 20 of the shaft side fixing tool 11, and a washer 29 is inserted into the screw hole 26 of the fixing drum 21 in a state of passing through the shaft side fixing tool 11. The screw 30 is screwed in and tightened, and the shaft fixing portion 17 of the shaft side fixing tool 11 is sandwiched between the fixing drum 21 and the screw 30 so as to be fixed to the shaft side fixing tool 11 so as not to rotate. .

  The engagement groove 28 is a groove that is recessed from the outer peripheral surface of the fixed drum 21 toward the center and is positioned to position the rotary drum 22 that rotates on the outer periphery of the fixed drum 21.

  A rotating drum 22 that rotates along the circumferential direction of the fixed drum 21 is attached to the outer periphery of the fixed drum 21. The rotary drum 22 is a cylindrical tube having an inner diameter that is large enough to surround the outer periphery of the fixed drum 21 and has one end face closed. On the opening end side of the rotary drum 22, a claw portion 31 that protrudes from the inner peripheral surface toward the center is provided. When the rotary drum 22 is externally fitted to the fixed drum 21, the claw portion 31 engages with the engagement groove 28 of the fixed drum 21 to fix the position of the rotary drum 22 with respect to the fixed drum 21. The claw portion 31 may be formed on the entire inner circumferential surface of the rotary drum 22 in the entire circumferential direction, or may be divided into a plurality along the circumferential direction.

  The spring 23 is, for example, a coiled torsion spring, and includes attachment ends 23 </ b> A and 23 </ b> B attached to the fixed drum 21 and the rotary drum 22 at both ends. The spring 23 constitutes a biasing means for biasing the winding shaft 12 in the winding direction of the sheet 14 by the fixed drum 21 and the rotating drum 22. The configuration of the urging means is not limited to this, and any configuration that can urge the rotating drum 22 in one direction with respect to the fixed drum 21 may be used. The mounting ends 23A and 23B of the spring 23 extend linearly along the axial direction of the spring 23 so that one mounting end 23A can be inserted into the locking hole 27A of the fixed drum 21, and the other mounting end 23B is a rotating drum. 22 extends linearly along the axial direction so that it can be inserted into a locking hole 22 </ b> A that penetrates the bottom of 22.

  With the above configuration, the support shaft 13 is assembled as follows. First, while the spring 23 is accommodated in the spring accommodating portion 27 of the fixed drum 21, one attachment end 23 </ b> A of the spring 23 is inserted into the engagement hole 27 </ b> A of the fixed drum 21 and is engaged. Next, the rotating drum 22 is extrapolated to the fixed drum 21 so that the rotating drum 22 surrounds the fixed drum 21, and the claw portion 31 is moved while the other attachment end 23 </ b> B of the spring 23 is passed through the locking hole 22 </ b> A. The support shaft 13 is formed by extrapolating until it engages with the engagement groove 28 of the fixed drum 21. The support shaft 13 rotates the rotating drum 22 with respect to the fixed drum 21 to twist the spring 23 and accumulate the restoring force. The stored restoring force becomes an urging force that urges the winding shaft 12 mounted on the rotary drum 22 in the sheet winding direction.

  The fixed drum 21 and the rotating drum 22 are made of resin, for example. Further, the fixed drum 21 may be made of metal and the rotary drum 22 may be made of resin. Further, a ball bearing or a fluorine resin as a solid lubricant is interposed between the fixed drum 21 and the rotating drum 22 so that the rotating drum 22 rotates more smoothly with respect to the fixed drum 21. Also good.

  A take-up shaft 12 that winds up the sheet 14 is fitted on the outer periphery of the rotary drum 22 having the above-described configuration. The winding shaft 12 is a cylindrical tube having a predetermined length, for example, a length longer than the width of the sheet 14 covering the opening 2 </ b> A of the loading platform 2. A sheet 14 is wound around the outer periphery of the winding shaft 12.

  In this embodiment, the sheet 14 is formed in a rectangular shape larger than the opening 2A of the loading platform 2 because the opening 2A of the loading platform 2 is formed in a substantially rectangular shape. The sheet 14 is wound around the winding shaft 12 in a state where one of the short sides of the four sides is fixed by a fixing means (not shown) in parallel with the axis of the winding shaft 12. The sheet 14 is made of a material having heat insulating and waterproof functions. As the structure of the sheet 14, for example, a cloth made of a waterproof material is applied to the surface side when the opening 2 </ b> A of the loading platform 2 is covered, and a cloth made of a material having heat insulation such as a nonwoven fabric is applied below the cloth. In addition, the sheet 14 is configured by stacking a plurality of fabrics having different functions into a sheet shape by applying a fabric made of a material having excellent antifouling properties to the back surface facing the luggage underneath. The The form of the seat 14 is not limited to the above, but preferably has a heat insulating and waterproof function, thereby suppressing the influence of the external environment such as direct sunlight, rain, and changes in temperature on the cargo stored in the loading platform 2. It becomes more effective as a cover that can.

  The lateral direction of the loading platform 2 corresponds to the width direction of the sheet 14, and the longitudinal direction of the loading platform 2 corresponds to the extending direction of the sheet 14. And when the winding shaft 12 rotates, the sheets 14 are wound in a stacked state.

As shown in FIG. 1, the seat 14 is provided with a seat fixture 15 for fixing a front end portion 14 </ b> F serving as a feeding end from the winding shaft 12 to the handcart 1.
The sheet fixture 15 has a length longer than the width of the opening 2A of the loading platform 2, and is composed of a long flat plate that is hardly bent when bridged to the left and right beads 5 of the opening 2A. It is composed of a magnet formed into a flat plate shape. The sheet fixing tool 15 is fixed to the surface 14a side of the sheet 14 by a fixing means such as an adhesive along the extending direction of the front end portion 14F of the sheet 14.
The magnetic force of the magnet has an attractive force that resists the urging force when the winding shaft 12 winds the sheet 14.

  Thus, if the sheet fixture 15 is comprised with a magnet, the sheet fixture 15 can be adsorbed and fixed to arbitrary positions with respect to the bead 5 of the loading platform 2 made of iron. By adsorbing the sheet fixing tool 15 to the bead 5, the sheet 14 can be sandwiched between the bead 5 and the sheet fixing tool 15 to close the opening 2 </ b> A. The sheet 14 is unwound from the take-up shaft 12 so as to cover the entire surface of the opening 2A, and the sheet fixing tool 15 is adsorbed to the front side wall surface of the loading platform 2 or the front end of the bead 5, so that the entire area of the opening 2A is seated. Can be completely occluded. Further, if the sheet fixing tool 15 is moved halfway in the front-rear direction of the opening 2A from the state where the entire area of the opening 2A is completely closed by the sheet 14 and is adsorbed to the bead 5, the sheet fixing tool 15 is moved. The opening 2A is opened while the sheet 14 is wound around the winding shaft 12, and the remaining opening 2A can be maintained closed without causing the sheet 14 to bend.

  Hereinafter, an installation example of the cargo bed cover 6 will be described with reference to FIG. In order to cover the entire opening 2A with the sheet 14 of the loading platform cover 6, it is preferable that at least the winding shaft 12 is disposed outside the opening 2A. Therefore, the shaft-side fixtures 11 and 11 are respectively attached to the beads 5 extending in the longitudinal direction so that the shaft-fixing portion 17 of the shaft-side fixture 11 is located behind the rear portion of the opening 2A. By attaching the shaft side fixing tools 11; 11 to the bead 5 in this way, the sheet 14 fed out from the winding shaft 12 is fed out while contacting the rear part of the bead 5, so that the opening 2 A of the loading platform 2. Can be completely closed from the rear end side.

  Next, the support shaft 13 is fixed to each shaft fixing portion 17. At this time, when the rotating drum 22 is rotated with respect to the fixed drum 21, the urging directions acting on the rotating drums 22 attached to the left and right are attached in the same direction and supported by the support shaft 13. The take-up shaft 12 is attached so as to take up the sheet from the lower side.

  Next, the winding shaft 12 is attached between the rotating drums 22 positioned on the left and right sides of the opening 2A. In addition, in the attachment of the winding shaft 12, it attaches so that the sheet | seat 14 previously wound around the winding shaft 12 may be let out from the lower side of the winding shaft 12. By attaching the take-up shaft 12 in this way, the sheet 14 fed out from the take-up shaft 12 comes into contact with the bead 5 that forms the opening 2 </ b> A, and it is difficult to form a gap between the bead 5. be able to.

  Next, handling of the cargo bed cover 6 attached to the handcart 1 will be described. First, the case where all the openings 2A are closed will be described. In this case, the operator holds the sheet fixing tool 15 at the front end portion 14F of the sheet 14 and pulls the sheet 14 in the extending direction of the opening 2A, whereby the sheet 14 is fed out from the winding shaft 12. At this time, the rotary drum 22 rotates with the take-up shaft 12 relative to the fixed drum 21, and the direction opposite to the direction in which the sheet 14 is unwound on the spring 23 provided between the fixed drum 21 and the rotary drum 22. Force (restoring force), that is, the force in the direction of winding the sheet 14 is accumulated. The worker adsorbs the sheet fixture 15 to the front end of the bead 5 or the wall of the loading platform 2 beyond the front end, so that the entire area of the opening 2A is covered with the sheet 14.

  Next, the case where the opening 2A is opened at an arbitrary position from the state where the entire area of the opening 2A is covered with the sheet 14 will be described. In this case, the operator lifts the sheet fixing tool 15 and moves the sheet fixing tool 15 along the extending direction of the opening 2A until a desired range of opening is obtained. The surplus sheet 14 generated as a result of this movement automatically rotates the take-up shaft 12 in the sheet take-up direction by the biasing force in the sheet take-up direction accumulated in the spring 23 when the take-up shaft 12 is fed out. Rolled up. When the opening of the desired range is obtained in the opening 2A, the operator abuts the bead 5 so that the sheet fixing tool 15 is stretched over the bead 5 extending in the front-rear direction with one hand. Thus, the sheet fixture 15 is fixed to the bead 5 by magnetic force and closes the opening 2A. That is, the urging force in the sheet take-up direction accumulated in the spring 23 of the support shaft 13 by the drawing of the sheet 14 from the take-up shaft 12 acts on the take-up shaft 12. The opening 2 </ b> A can be opened in a desired size without being wrinkled by 14.

In the above-described embodiment, the shaft-side fixing tool 11; 11 is provided so as to be opposed to the left and right beads 5 extending in the front-rear direction, and the load-carrying cover 6 is attached to the load-bearing 2; ; 11 may be provided opposite to the front and rear beads 5 extending in the left-right direction.
That is, the take-up shaft 12 of the cargo bed cover 6 may be provided so as to extend in the front-rear direction of the cargo bed 2, and the opening 2A of the cargo bed 2 may be configured to open and close in the left-right direction.

Next, another embodiment of the installation example of the cargo bed cover 6 will be described with reference to FIG.

The sheet fixing tool 15A of the sheet 14A is fixed by a magnetic force, and the sheet fixing tool 15B of the sheet 14B fed forward from the cargo bed cover 6B attached to the rear side of the opening 2A is overlapped with each other. By fixing, the entire area of the opening 2A can be covered by the two cargo bed covers 6A; 6B sheets 14A; 14B. In this case, the sheet fixture 15B is fixed by the mutual magnetic force of the sheet fixture 15A.

  Further, in this embodiment, the shaft fixing portion 17 of the shaft side fixing tool 11A of the loading platform cover 6A covering the front side of the opening 2A is attached so as to be positioned in front of the front end of the bead 5, and the rear side of the opening 2A is covered. Although the shaft fixing part 17 of the shaft side fixing tool 11B of the loading platform cover 6B is attached so as to be located behind the rear end of the bead 5, the shaft side fixing tool 11A of the loading platform cover 6A covering the left side of the opening 2A is used. The shaft fixing portion 17 is attached so that it is located on the left side of the left end of the bead 5, and the shaft fixing portion 17 of the shaft side fixing tool 11 </ b> B of the loading platform cover 6 </ b> B covering the right side of the opening 2 </ b> A is located on the right side of the right end of the bead 5. You may comprise so that it may attach.

In addition, since the seat 14 has heat insulation and waterproof properties, the baggage can be shielded from the sun's sunshine and sudden rain while the baggage is being transported, and is less susceptible to the temperature of the outside air. it can. In addition, the sheet 14 is tensioned in one direction by the urging force of the support shaft 13, and can prevent the sheet 14 from flapping or dropping into the accommodation space due to the influence of wind.
Therefore, since the load can be transported while maintaining the state and environment when the load is loaded on the loading platform 2, for example, although it is easily affected by the outside such as concrete, it is hardly affected by the outside. Can be transported.

  As mentioned above, although this invention was demonstrated using embodiment, the technical scope of this invention is not limited to the said embodiment. It will be apparent to those skilled in the art that various changes and modifications can be made to the above-described embodiment, and it is obvious that such changes and modifications can be included in the technical scope of the present invention. It is clear from the description.

For example, the shaft fixing hole 20 formed in the shaft fixing portion 17 of the shaft-side fixture 11 may be formed as a long hole extending in the vertical direction of the shaft fixing portion 17 so that the support shaft 13 can be moved in the vertical direction. . By forming the shaft fixing hole 20 in this manner, the position of the support shaft 13 with respect to the periphery of the bead 5 is moved when the sheet 14 is fed out from the winding shaft 12 or taken up on the winding shaft 12. Therefore, the distance of the sheet 14 with respect to 5 can be kept constant, and the closed state of the opening 2A can be reliably maintained. For example, every time the sheet 14 is fed out from the winding shaft 12, the radial distance between the sheet 14 fed out from the winding shaft 12 and the center of the winding shaft 12 gradually decreases, and the fed sheet 14 becomes smaller. Although it is conceivable that the bead 5 is separated in the vicinity of the take-up shaft 12, the position of the take-up shaft 12 can be moved in the vertical direction, so that the distance between the sheet 14 and the bead 5 is kept constant. 2A blockage can be ensured. In this manner, by bringing the sheet 14 and the bead 5 into close contact with each other, it is possible to prevent dust and the like from entering the cargo bed more reliably.
When the baggage needs ventilation, a predetermined gap is set between the seat 14 and the bead 5 so that the baggage is protected from rain and the sun, and the opening 2A is opened in the space. Can be done through ventilation.

  Further, the sheet fixture 15 has been described as a flat plate having a magnetic force, but may be configured by providing a magnet on a flat plate made of a material having no magnetic properties. The sheet fixture 15 is not limited to a magnet, and may be configured by attaching a hook that can be locked to the bead 5 to a plate piece that is longer than the width of the opening 2A and hardly bends. That is, as the sheet fixture 15, a sheet fixing member 15 having any shape and function can be adopted as long as the sheet 14 can be closed against the urging force generated in the winding shaft 12.

  Further, the shape of the sheet 14 is not limited to the rectangular shape described above, and the shape may be appropriately changed so as to correspond to the shape of the opening 2A. For example, when the shape of the opening is an egg shape, the shape of the sheet may be an egg shape, and when the shape of the opening portion is a round shape, the shape of the sheet may be a round shape.

  Moreover, the spring 23 which comprises the support shaft 13 which is an urging | biasing means may be comprised not only with a torsion spring but with a rubber string. For example, one end of a rubber band formed in an annular shape is fixed to the fixed drum 21 and the other end is fixed to the rotary drum 22 or the winding shaft 12 so that the rubber string is twisted when the winding shaft 12 rotates. Thus, the urging force in the sheet winding direction can be applied to the winding shaft 12.
