Description

[Detailed description of the invention] This invention relates to a tilt support device for a truck, and more specifically, it includes a tilt support support that is rotatable outwardly with respect to the floor of a truck bed, and a tilt support support for this support. This invention relates to an improvement in a tilt support device for a truck, which includes a support section that is installed in a lower loading platform section and selectively supports a column.

A conventional tilt support device of this type is shown in Figures 1a to 1c.
As shown in the figure, a tilt support slide c that is removably fitted into a cylindrical guide b installed on the platform floor a is connected to a V-shaped link e having a handle d, and a V-shaped link e having a handle d. It was operated by a link mechanism g consisting of a corner part and a straight link f pivoted to the slide body c, respectively. Therefore,
The operation is complicated because it is necessary to perform the operation each time the tilter is opened or closed, and moreover, it is necessary to perform the operation with a relatively large amount of force. In addition, there is a risk that the links e and f may shift to the left due to vibrations during driving, causing the slide body c and the tilt mechanism to be inadvertently disengaged. There is a risk of causing an accident.

This invention was made with the intention of solving the above problem, and its purpose is to make it possible to easily open the swing by simply operating it with a small amount of force, and to It is an object of the present invention to provide a tilt support device for a truck, which is characterized in that the tilt support is prevented from being loosened even by vibrations during traveling.

In other words, the gist of this invention is to have a tilt-holding column that is rotatable to open outward relative to the floor of the truck loading platform, and a tilt-holding column that is installed on the loading platform below this column to selectively support the column. In a truck swing support device comprising a support part,
The support part is composed of a guide that guides in the vertical direction, and a support slide that slides retractably along the guide and engages in the lower recess of the column when projected upward, and , the slide body has
This slide body is made up of an elastic means that can project upward at all times, and also connects the end of the cable to be wound around a winding means installed at a separate position. This invention relates to a tilt support device for a truck, characterized in that the sliding body and the support can be disengaged from each other by a handling operation to open and close the tilt.

Examples of this invention will be described below with reference to FIGS. 2 to 7.

FIG. 2 shows a schematic side view of a truck having a tilt support device of this invention. A tilt support device 7 of this invention is attached to adjacent parts of two tilt tilts 5 and 6 attached with a hinge 4.

As shown in FIG. 3, the tilt support device 7 is fixed to the edge of one of the tilts 5 and 6, and rotates together with the tilt 5 to open outward relative to the platform floor 3. A tilt holding post 8,
The main part is constituted by a support section 10 that is installed below the support column 8 on the platform floor side and selectively supports the support column 8. In this case, a recess 9 is provided on the lower surface of the support column 8, into which a support slide 13, which will be described later, can be thrust into engagement.

On the other hand, as shown in FIG. 4, the support section 10 has vertically guiding portions formed on at least both sides of the trapezoidal mounting plate 11 fixed to the platform floor side. A guide 12 having a rectangular cylindrical shape at the bottom is slidably fitted into the guide 12 so as to protrude and retract above the guide 12, and to engage in the lower recess 9 of the support column 8 when projected upward. It is composed of a supporting slide body 13. In this case, two through holes 14, 14 are bored in the slide body 13, parallel to each other in the sliding direction. guide rod 15,
15 is loosely inserted, and a coil spring 16, which is an elastic means, is compressed between the slide body 13 and the guide bottom part 12a via this guide rod 15, and the elastic force of this coil spring 16 allows the slide to be maintained at all times. The body 13 is designed to protrude upward (fifth
(see figure). Further, the guide 12 on the mounting plate 11
A winding sheave 18, which is a winding means for winding a cable 17 such as a wire rope for operation, is located at a position separated from the winding sheave 18.
is mounted rotatably in the vertical direction, and the cable 17 wound around this winding sheave 18 is also attached to the mounting plate 1.
1 is guided by a guide sheave 19 rotatably attached to the guide 14, and guided into the guide 14 through a through hole 20 bored in the guide bottom 12a.
Its end portion is connected to the slide body 13 by screw connection or the like. In this case, the winding sheave 18 is formed to have a larger diameter than the guide sheave 19, and is rotated by a flank-shaped handle 21 attached to its rotating part, and is rotated by winding the cable 17. By winding up the cable 17, the slide body 13 is lowered against the coil spring 16 and disengaged from the lower recess 9 of the support column 8.

Reference numeral 22 denotes a handle stopper projecting from the mounting plate 11, which includes a mounting portion 22a pivotally mounted to the mounting plate 11, a stopper portion 22b projecting at right angles from the tip of the mounting portion 22a, A part of this stopper part 22b is composed of a handle receiving part 22c bent like a gutter.

On the other hand, a latch 24 that removably engages with a receiver 23 protruding from the edge of the other adjacent tilt 6 is rotatably attached to the support column 8 . Therefore, by removing the latch 24 from the receiver 23, only the tilt 6 can be tilted down, as shown in FIG.

Note that the means for holding the tilt 6 on the support 8 does not necessarily have to be the receiver 23 and the latch 24; for example, as shown in FIG. Hanging tool 26 that appears on the side
It may be of a sliding type, in which it is removably engaged with a receiving part 27 provided at the edge of the tilt direction 6. In this case, only the tilt 5 can be folded down, and the watertightness between the tilt 6 and the support 8 can also be improved.

In the tilt support device of the present invention constructed as described above, when tilting the tilt tilts 5 and 6 to the open state, hold the handle 21 and hold the winding sheave 1.
8 to wind up the cable 17, the slide body 13 descends against the coil spring 16 and is disengaged from the lower recess 9 of the column 8. In this state, the handle 21 is rotated. When engaged with the handle receiving portion 22c of the handle stopper 22 (see FIG. 5), the tilters 5 and 6 can be tilted in the opening direction. In addition, when the tilters 5 and 6 are raised in the closing direction, as shown in FIG.
is maintained within the guide 12, and after raising the tilters 5 and 6, the handle 2 is
1 from the handle stopper 22, the slide body 13 rises due to the elastic force of the coil spring 16 and engages in the lower recess 9 of the column 8, so that the column 8
And the tilt 5 integrated with the support 8 is supported, and
The other tilter 6 is also supported via the latch 24 or the hook 26.

In addition, although the above-mentioned example explained the case where the support column 8 was fixedly installed on one side of the tilter 5, it is not necessarily necessary to be fixedly installed on the tilter, and it can be freely rotated with respect to the platform floor independently of the tilter. In this case, the latch 24 or hook 26 attached to the pillar may be engaged with the left and right tilters 5 and 6.

As explained above, according to the tilt support device of this invention, the support part that selectively supports the tilt support column has a guide that guides it in the vertical direction and a guide that slides in a retractable manner along the guide. and a support slide body that engages in the lower recess of the support column when projected upward, and the slide body is biased with elastic means that can constantly project the slide body upward, and the slide body is provided with an elastic means capable of constantly projecting the slide body upward, and the support slide body is provided with an elastic means capable of constantly protruding the slide body upward. Since the ends of the operating cables wound around the winding means attached to the winder are connected to each other, the tilter can be opened and closed with simpler operation and with less force than conventional tilt support devices of this type. In addition, since the tilt support state can be maintained reliably and firmly, there is no risk of the tilt tilt inadvertently tipping over to the open side due to vibrations while driving, etc. Its utility value is remarkable because it provides excellent effects such as ensuring safety.
