Description

[Detailed explanation of the idea] [Industrial application field]

The present invention relates to a hood support structure for an automobile with a hood.

[Conventional technology]

Many four-wheel drive vehicles for off-road driving are equipped with a canopy to cover the cargo bed behind the passenger compartment. Such vehicles are provided with a portal-shaped hood frame that is supported between the center or rear end of both side frames of the cargo bed so that both legs can rotate in the longitudinal direction of the vehicle body. , and is configured to cover the cargo bed with the rear proper portion supported by a horizontal shaft extending in the vehicle width direction between the legs of the top bone. In addition, normally, the top is fixed to the vehicle body by first fixing the middle portion of the top to the horizontal shaft portion of the top rib in the vehicle width direction so that the top has a box shape.
This is done by hooking the bottom of the hood to the vehicle body. In other words, the front hem of the hood in the longitudinal direction of the vehicle body is connected to the gate-shaped roll bar that separates the passenger compartment from the cargo bed, the hem portions on both sides are connected to the frames on both sides of the cargo bed, and the rear hem are each hooked to the rear frame of the cargo bed. The hood is removable, and when the hood is not needed, the hood and hood ribs can be stored on the carrier. To remove the hood, remove the hooks at the bottom of the hood, tilt the hood ribs in an upright position, and rotate them.
The top and the top rib are stored on the loading platform by folding the top. In addition, when attaching the top rib, contrary to the above, the top rib is rotated to stand up while lifting the front end hem of the hood, covers the cargo bed, and the hem is hooked to the vehicle body.

[Problem that the idea aims to solve]

However, with the top configured as described above, if you try to set the roof height of the top to the same height as the roll bar, the position of the horizontal axis of the top frame in the vehicle width direction must be set to the above ceiling position. Instead, it is necessary to lengthen the legs of the canopy or move the supporting part of the canopy backwards. However, when the legs are lengthened or the support part of the top bone is moved rearward, when the top bone is tilted backward and rotated in order to remove the top, the horizontal axis in the vehicle width direction of the top of the top bone will move behind the cargo bed. This will protrude rearward from the end, making it impossible to store the canopy inside the cargo platform. Another option is to lengthen the legs of the hood bone and move the support part of the hood bone toward the front of the vehicle, but this would make the hood support unstable and pose a structural problem. , a window formed by a transparent sheet is provided, and as described above, when the supporting part of the canopy bone is moved forward, the leg part of the canopy bone crosses the inside of the window, and the lateral visibility is Problems of deterioration and deterioration in lateral appearance also arise. Furthermore, as mentioned above, the hood is attached by hooking the bottom of the hood to the vehicle body.
Since the work was done manually, it was impossible to install the top without any slack, and this looseness made the overall appearance of the covered vehicle unsatisfactory. In order to solve the above problem, for example, as shown in Japanese Utility Model Application Publication No. 57-33529, a guide rail having a straight rail groove is installed on the upper surface of both side frames of the loading platform at the middle part in the longitudinal direction of the vehicle body. A structure has been proposed in which the ends of both legs of the top frame are supported so as to be slidable in the longitudinal direction of the vehicle body along the rail groove. However, the canopy bone support structure disclosed in the above-mentioned publication requires a fixing device for fixing the canopy bone in a fixed position when the canopy is attached, which complicates the device and increases costs. The present invention was devised under the above circumstances, and solves the above problems by setting the top height of the top to the same height as the roll bar without lengthening the legs of the top rib. Moreover, it is an object of the present invention to provide a top bone support structure for a car with a top, which can store the top and the top rib in the loading platform and can reduce slack when the top is attached.

[Means to solve the problem]

In order to solve the above problems, the present invention takes the following technical measures. That is, this is a canopy support structure for a car with a canopy, which has a canopy that covers the loading platform behind the roll bar in a box shape, and which penetrates in the vehicle width direction at the middle part of the upper surface of both side frames of the loading platform in the longitudinal direction of the vehicle body. Brackets each having an elongated support hole having a predetermined length in the front-rear direction are provided, and support shafts in the vehicle width direction provided at the ends of both legs of the canopy bone formed in a portal shape are inserted into each support hole of the bracket. an engaging portion that is slidably and rotatably inserted and supported, and that allows each of the support shafts to engage downwardly in each rear end portion of each of the support holes to prevent movement of the support shaft in the longitudinal direction of the vehicle body; It is characterized by having the following.

[Action and effect]

In the conventional canopy support structure, the canopy can only rotate around one axis at the longitudinally intermediate portion of both side frames of the cargo platform. Therefore, if you try to set the top ceiling height to the same height as the roll bar, the top rib will protrude outside the rear frame of the cargo bed when it is stored, and if you try to store the top bone in the cargo bed, A problem arose in that the ceiling height of the hood could not be set to the height of the roll bar. In the present invention, the support shaft provided in the vehicle width direction at the ends of both legs of the portal hood has an elongated support hole provided with an engaging part that is inserted and supported when the hood is installed. The above problem is solved by inserting and supporting the hood into the support hole of the bracket, rotatably supporting the top frame, and also making it slidable in the longitudinal direction of the vehicle body along the elongated support hole. It is something. The elongated support hole penetrates in the vehicle width direction and has a predetermined length in the longitudinal direction of the vehicle body, and the top is rotated with the support shaft of the hood bone positioned at the front end of the elongated support hole. When the top rib is tilted rearward and rotated to be stored in the cargo bed, the horizontal axis in the vehicle width direction of the upper portion of the top bone can be stored inside the cargo bed. The engaging part is formed in the rear end of the upper elongated hole so that the above-mentioned support shaft engages downward, and the canopy bone can be rotated with the support shaft of the canopy positioned in this engaging part. When the top bone is raised upright, the horizontal axis in the vehicle width direction at the top of the top bone can be raised to the same height as the roll bar, and the top bone can be fixed in a predetermined position by preventing the support shaft from moving in the front-rear direction of the vehicle body. can. By being inserted and supported in the elongated support hole, the support shaft of the top frame can slide in the longitudinal direction of the vehicle body and is rotatably supported. With the above configuration, when the top is stored, the top rib and the top can be stored without protruding from the loading platform, and when the top is installed, the ceiling height of the top can be set to the same height as the roll bar. It can be made into Furthermore, when installing the top, first, the top rib is erected with the support shaft of the top bone supported at the front end of the elongated support hole, and the hem of the top is hooked to the vehicle body. Attach the top with the hood, and then slide the support shaft of the hood bone backwards so that it engages the engagement part at the rear end of the long hole-shaped support hole. The installation work is easy because it can be done in the open position, and it is also possible to apply tension to the top after installation to eliminate slack.
