Description

[Technical field]

[0001] The present invention relates to a frame mechanism for attaching a planar member made of resin, cloth, etc., called a hood, sheet, etc. (hereinafter referred to as a "cover") that covers the opening of a box-shaped cargo bed that is rectangular in plan view and open at the top behind the driver's seat, known as a light truck. [Background technology]

[0002] Generally, such covers consist of multiple rubber bands arranged at regular intervals around the periphery of the loading platform, which an operator can manually fasten to hooks on a guard frame located around the periphery of the loading platform or on the outside behind the driver's seat to cover the opening of the loading platform and thereby cover agricultural produce, work tools, work clothes, and other cargo placed on the loading platform. These covers are used to prevent cargo from falling over while the vehicle is traveling, or to protect the cargo from the surrounding environment, such as rain, snow, and birds, and are quite heavy as their surface is waterproofed to ensure durability (see Patent Document 1 below).

[0003] The covers come in a variety of sizes depending on the size of the cargo bed, but even if you select a sheet to match the size of the cargo bed, if the amount of luggage is small, the cover may extend beyond the cargo bed, creating a driving hazard or hang down inside the cargo bed, allowing rain, etc. to accumulate. Conversely, if the amount of luggage is large, the cover may be pulled upwards, resulting in an insufficient length from side to side or front to back, creating a gap between the cargo bed and the cover, allowing rain, etc. to enter the cargo bed.

[0004] In addition, when attaching the sheet to the cargo bed (when attaching), all of the rubber bands need to be engaged with the hooks so that the tension of the sheet is approximately uniform throughout; conversely, when removing the sheet (when dismounting), the sheet may suddenly roll up due to the influence of the wind, or the sheet needs to be folded up or stored; in either case, the worker needs to move around the cargo bed while performing the work, which is cumbersome to perform alone and takes time, etc.

[0005] Alternatively, there are shed-type covers (see Patent Documents 2 and 3 below), but because they are fixed to the vehicle, they cannot be attached or detached depending on the use of the cargo bed. Furthermore, in those cases where the frame is installed higher than the driver's seat of the vehicle, it is not possible to see behind through the rearview mirror from inside the driver's seat, which causes a problem of worsening the usage environment of the vehicle.

[0006] In order to address such conventional problems, a metal frame is used to enable the cover to be easily attached and detached (see Patent Documents 4 to 6 below). [Prior art documents] [Patent documents]

[0007] [Patent Document 1] Publication No. 7-17643 [Patent Document 2] Patent No. 6209713 [Patent Document 3] Patent No. 6864777 [Patent Document 4] Japanese Utility Model Application Publication No. 5-80842 [Patent Document 5] Utility Model Registration No. 3176714 [Patent Document 6] Utility Model Registration No. 3189327 Summary of the Invention [Problem to be solved by the invention]

[0008] In the devices disclosed in the above Patent Documents 4 to 6, the cover is attached to the frame in advance, so that the cover can be attached and detached from the loading platform relatively easily. However, in all cases, the work must be done while moving around the loading platform, and the final fastening requires, as in the past, multiple rubber bands to be hooked onto the hooks on the loading platform, etc., which is cumbersome.

[0009] As such, in the conventional technology, the task of loading and unloading luggage onto the cargo bed is complicated, and there is room for improvement from the standpoint of reducing the labor required by workers. Therefore, the present invention aims to provide a cover mounting frame mechanism for a vehicle cargo bed, which enables the cover to be opened and closed quickly and easily, and also enables the cover to be easily attached and removed. [Means for solving the problem]

[0010] The vehicle cargo bed cover mounting frame mechanism of the present invention is a frame mechanism for mounting a cover that covers the opening of a box-shaped cargo bed behind the driver's seat, the upper part of which is open, and is made up of a roof-shaped framework structure to which the cover is mounted from above, the framework structure having a front part with respect to the vehicle's travel direction, a rotation support member installed at the front upper end part so as to be freely attached to and detached from the vehicle and to be rotatable in the vertical direction with the attachment point as a fulcrum, and a lock member installed at the rear lower end part so as to be freely fixed and released between the framework structure and the cargo bed, The locking member is released, and the rear part is lifted upward away from the loading platform. and a support for keeping the rear section clear of the cargo bed when the front section is rotated upward.

[0011] In particular, the roof shape has a flat top with downward sloping sections on the left and right, the front portion has a shape similar to a trapezoidal gable roof, and the rear portion has a shape similar to a hip roof with a trapezoidal rear surface connecting the flat portion and each surface of the left and right sloping sections, and the flat portion and the rear surface connected to this flat portion slope downward when viewed from the front. Effect of the Invention

[0012] According to the present invention, the cover can be opened and closed easily in a short time, and cargo can be loaded and unloaded onto the loading platform without the need to attach and detach the cover.

[0013] In addition, rain or the like on the surface of the cover can be efficiently guided and drained around the loading platform. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0015] Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings.

[0016] FIG. 1 shows a cover mounting frame mechanism (hereinafter referred to as the "frame mechanism") 200 according to the present invention, with a cover 300 attached to the cargo bed 110 of a vehicle 100, installed. As shown in FIG. 2, the frame mechanism 200 is a framework structure made up of metal pipes and joints, as described below, and a resin cover 300 having a shape that fits the outer shape of the waterproofed frame mechanism 200 is attached by an appropriate means so as to cover this framework structure from above.

[0017] In other words, the frame mechanism 200 is a framework structure made up of a number of straight pipes 210 so that the entire structure has a roof shape with a gable roof at the front and a hipped roof at the rear in the direction of travel of the vehicle 100, and a number of I-, L-, T- or other appropriate shaped joints 220 that connect these pipes 210, and the pipes 210 are connected by the joints 220 so that they have functions equivalent to the purlins, eaves beams, roof beams, rafters and roof trusses of a roof structure, and there is no part equivalent to the ridge beam of a roof structure, and the top part is flat.

[0018] A rotary bearing member 221 with a hollow center is provided at the left and right ends of the front pipe 211 of the frame mechanism 200 (the position connecting the left and right main roofs of the roof structure), and a pillar rotation portion 222 is provided at two locations on the left and right of the rear pipe 212 of the frame mechanism 200 (corresponding to the rafters of the roof structure), but the rotary bearing member 221 and the pillar rotation portion 222 can also be combined into a joint 220.

[0019] The frame mechanism 200 fitted with this cover 300 has a front pipe 211 connected to a horizontal point of the guard frame 130, which is part of the vehicle 100 located outside behind the driver's seat 120 of the vehicle 100, and a rear pipe 212 positioned and fixed at the upper end of the rear tailgate 111, which is part of the movable partition wall surrounding the periphery of the cargo bed 110 (Figure 3).When fitted in this manner, the front of the frame mechanism 200 is made lower than the rear window so that the frame mechanism 200 with the cover 300 fitted does not obstruct the rear view of the driver's seat 120, and the flat portion of the frame mechanism 200 and the trapezoidal rear surface portion connected to this flat portion are inclined downward when viewed from the front to ensure a water gradient that allows rain, etc. on the surface of the cover 300 to be naturally drained.

[0020] A rotating support member 400 (Fig. 4(a)) using a round drop fitting hardware, for example a SYS Jibutani product (product name: round drop, product number: DL-153S-1), is installed in at least one location on the guard frame 130 (two locations, left and right, in this embodiment). When the lever 401 is operated to move the associated lock pin 402 laterally and insert its tip into the rotating bearing member 221 (Fig. 4(b)), the frame mechanism 200 is supported horizontally on the guard frame 130 from the outside left and right, and the front pipe 211 can rotate up and down with the lock pin 402, which is the attachment point, as a fulcrum.

[0021] In other words, the rotation support member 400 is installed so that the frame mechanism 200 with the cover 300 attached can rotate up and down around the front pipe 211 located at the upper base of the front trapezoidal surface of the frame mechanism 200, which is the front upper end point of the frame mechanism 200.

[0022] In this way, since the front of the framework structure can be freely attached and detached to the vehicle 100 in the direction of travel of the vehicle 100, the front of the frame mechanism 200 with the cover 300 attached thereto can be freely attached and detached to the vehicle 100 and can also rotate in the vertical direction with the attachment point as a fulcrum.

[0023] The rear pipe 212 and the rear gate 111 of the cargo bed 110 shown in Figure 3 are installed so as to be freely fixed and released by an openable and closable locking member 500, such as "Product name: Rubber Bonnet / Boot Hooks, product number: GE63" manufactured by Grayston Engineering Limited. The rubber hook receiver 501 (Figure 5(a)) is installed on the rear pipe 212 side and the rubber hook 502 (Figure 5(b)) is installed on the rear gate 111 side. By fitting the rubber hook 502 into the rubber hook receiver 501 (Figure 5(c)), the rear pipe 212 is held in a resting state on the upper end of the rear gate 111 and the frame mechanism 200 with the cover 300 attached can be fixed to the cargo bed 110.

[0024] In other words, the rear pipe 212 located at the lower base of the rear trapezoidal surface of the frame mechanism 200, which is the rear lower end point of the frame mechanism 200, is held in a resting state on the upper end of the rear gate 111 of the cargo bed 110, and a locking member 500 is installed so that the frame mechanism 200 with the cover 300 attached can be fixed to the cargo bed 110.

[0025] In addition, a straight-line pillar 600 whose tip extends perpendicular to the rear pipe 212 and whose free end is connected to the pillar rotation section 222 provided on the rear pipe 212 (Figure 6), and when the frame mechanism 200 is fixed to the loading platform 110, the free end of this pillar 600 slides forward inside the loading platform 110 with the pillar rotation section 222 as a fulcrum and is stored inside the frame mechanism 200 (Figure 7(a)). When the locking member 500 shown in Figure 5 is released and the rear pipe 212 of the frame mechanism 200 is lifted upward away from the rear gate 111 of the loading platform 110, the front pipe 211 rotates up and down with the rotating bearing member 221 as a fulcrum as shown in Figure 4, and at the same time, the free end of the pillar 600 stands upright vertically on the floor of the loading platform 110 with the pillar rotation section 222 as a fulcrum (Figure 7(b)).

[0026] In this way, the rear end of the framework structure in the traveling direction of the vehicle 100 can be freely fixed and released between it and the cargo bed 110, and the rear end of the frame mechanism 200 equipped with the cover 300 can be freely fixed and released between it and the cargo bed 110 of the vehicle 100.

[0027] With this configuration, the cover 300 opens and closes integrally with the frame mechanism 200. Therefore, by configuring the frame mechanism 200 to have the same planar dimensions as the gate surrounding the loading platform 110, the entire underside of the frame mechanism 200 is shaped to rest on the upper end of the gate, so that rain and other liquids on the surface of the cover 300 can be efficiently guided around the loading platform 110 and drained away.

[0028] In particular, the cover 300 can be opened and closed by simply operating the locking members 500 at two locations on the rear of the loading platform 110 to release the rear pipe 212 from the rear gate 111, so that the cover 300 can be opened and closed easily in a short time, and cargo can be loaded and unloaded onto the loading platform 110 without the need to attach and detach the cover 300.

[0029] In other words, since the frame mechanism 200 having the cover 300 attached thereto has a support pillar 600 for keeping the rear of the frame mechanism 200 away from the loading platform 110 when the front of the frame mechanism 200 is rotated upward, when the cover 300 is opened, the support pillar 600 automatically rotates vertically due to its own weight and is then maintained in an upright position on the loading platform 110, making it easy to open the frame mechanism 200 including the cover 300 with little force.

[0030] In this case, it is possible to carry long items into and out of the platform 110 through the spaces between the pillars 600 by tilting the rear gate 111, improving workability.

[0031] Then, by simply knocking down the support 600, the weight of the frame mechanism 200 and the cover 300 completes the closing of the frame mechanism 200 and the cover 300.

[0032] Furthermore, when the cover 300 is not required, the cover 300 can be removed from the cargo bed 110 together with the frame mechanism 200 by opening the locking member 500 and removing the front pipe 211 from the rotating support member 400, thereby facilitating the installation and removal of the cover 300.

[0033] With this configuration, the frame mechanism 200 of the present invention can not only serve to attach and detach the seat 300 to the cargo bed 120, but can also utilize the seat 300 as a roof or eaves, so that not only can it protect luggage, but the vehicle 100 can also be used as a mobile store, exhibition space, etc.

[0034] As described above, it is optimal for the external shape of the frame mechanism 200 to have a flat top portion with downward sloping portions on the left and right, with the front portion having a shape similar to a trapezoidal gable roof so that it can rotate up and down after being fixed to the guard frame 130 of the vehicle 100, and the rear portion having a shape similar to a hip roof having a trapezoidal rear surface connecting the flat portion and each surface of the left and right inclined portions, but it goes without saying that other shapes are possible within the scope of the gist of the present invention.

[0035] The frame mechanism 200 is manufactured so that the pipe 210 rests on the tailgate of the loading platform 110 according to the shape of the loading platform 110 of the vehicle 100 to which it is applied. However, if the pipe 210 can be changed in the length direction, the user can change and adjust the shape of the same frame mechanism 200 according to the dimensions of the loading platform 110 when changing the vehicle 100.

[0036] In this way, the frame mechanism 200 can be constructed from pipes of any shape as a special design tailored to the shape of the cargo bed 120 of the vehicle 100 to be used, but can also be manufactured inexpensively by using commercially available general-purpose pipes 210 and joints 220.

[0037] In addition, although it is convenient for the frame mechanism 200 and the cover 300 to have a fixed structure so that they can be operated as a unit, it is also possible to make the cover 300 detachable so that it can be replaced in response to changes over time due to use.
