Description

[Detailed explanation of the invention] This invention is suitable for displaying products, playing music, etc.
This invention relates to an exhibition vehicle suitable for theatrical performances, etc.

For exhibition vehicles, there is a strong desire to use the side gates as an extended floor surface in addition to the vehicle body floor surface when the side gates are open. However, if the side gate is simply fixed in the open state, the vehicle will tilt and shake, resulting in a high degree of danger and a lack of stability.

In view of the above points, the present invention prevents the vehicle from tilting, shaking, etc. by providing a gate support device that supports the side gate when the side gate of a vehicle with side openings is opened and used as an extended floor surface. The aim is to provide exhibition vehicles with improved safety.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Examples of exhibition vehicles according to the present invention will be described below with reference to the drawings.

In FIGS. 1 to 5, a box-shaped vehicle body 1 of a side-open vehicle has a single-slope roof 2 that constitutes about half of its top surface and the upper side surface, and a side gate 3 that forms the side surface of the box-type vehicle body 1 together with the single-slope roof. and a rear double-hung door 4. Here, the single-opening roof 2 is attached via a hinge to a central support 7 that connects the front wall 5 of the box-shaped vehicle body 1 and the upper center of the rear frame 6, and the side gate 3 is also attached to the box-shaped vehicle body. 1 via a hinge 9 so as to be openable and closable. The single-swing roof 2 is driven to open and close by a roof opening/closing mechanism consisting of a hydraulic cylinder 10 and a link mechanism 11. On the other hand, when the side gate 3 is open, it functions as an extended floor surface that is continuous with the floor surface 12 of the box-shaped vehicle body 1, and gate receiving devices 20 are provided at multiple locations to support the side gate 3. It is being

The gate receiving device 20 includes a gate support frame 21 that is provided on the floor 8 of the box-shaped vehicle body 1 so as to be freely drawn out.
A support post 23 is pivotally connected to the gate support frame 21 with a pin 22, and a gate stopper 24 is pivotally connected to the tip of the gate support frame 21 so as to be able to rise and fall freely. Here, the pillar 23 is stored in the gate support frame 21 in a state parallel to the gate support frame 21, and the gate stopper 24 is also stored in the gate support frame 21 in a state parallel to the gate support frame 21, that is, in a face down state. It is designed to fit into the recess 25 of 21. Furthermore, the gate stopper 24 has a hinge structure that prevents it from rotating any further after it has been rotated 90 degrees from the prone state to the upright state.
The boss 27 that enters is fixed. The pillar 23
A saucer 28 is screwed onto the threaded portion at the lower end of the holder. A spring-type stopper lock 31 is provided on the chassis frame 30 under the floor of the box-shaped vehicle body 1, and the stopper lock 31 can be locked when the gate support frame 21 is retracted into the floor portion 8.
Furthermore, when the boss 27 comes to the position where it is fitted into the fitting hole 26 of the side gate 3, the gate support frame 21 is engaged with a stopper member 34 at the rear end of the gate support frame 21 and locked. There is. The gate support frame 21 is slidably supported by a storage frame 32 on the floor 8 side so that the gate support frame 21 can be pulled out from the floor 8. A pin fitting 33 is provided on the tip end surface of the gate support frame 21 so that the operator can easily pull it out with his fingers.

In the above configuration, when the vehicle is running as a normal box-shaped vehicle, the roof 2 is closed by the roof opening/closing mechanism and the side gate 3 is vertically closed. Further, the gate support frame 21 is stored in the floor portion 8 and is locked in the stored position by a stopper lock 31. This allows it to run as a regular box-body freight vehicle. On the other hand, when exhibiting, the roof 2 is opened by the roof opening/closing mechanism, and the side gate 3 is opened horizontally. At that time, the operator unlocks the pin fitting 33 of the gate support frame 21 with his/her finger while the stopper lock 31 is unlocked in advance.
Pull the gate support frame 21 forward as shown in FIG. 3 to fully pull out the gate support frame 21. Then, as shown in Figure 4, erect the gate stopper 24 vertically and
3 is placed in a vertical state, a saucer 28 is screwed onto its lower end, and the threaded state of the saucer 28 and the support column 23 is adjusted so that the gate support frame 21 becomes almost horizontal. In this state, the side gate 3 is laid down horizontally and the boss 27 is fitted into the fitting hole 26 on the gate side. At this time, the spring type stopper lock 31 engages with the stopper member 34 of the gate support frame 21 and automatically locks the gate support frame 21 when the boss 27 and the fitting hole 26 are in the fitted state.

According to the configuration of the above embodiment, since the side gate 3 can be reliably supported on the ground by the gate receiving member 20, tilting and shaking due to the weight applied to the side gate 3 of the box-shaped vehicle body 1 can be prevented, and the vehicle body floor It is possible to stabilize the surface and improve safety.

Although the above embodiment shows a structure in which the saucer 28 is provided separately from the support column 23, a foldable saucer 28A is provided at the tip of the column 23 as shown in FIG. It can also be a retractable structure.

As explained above, according to the present invention, the exhibition vehicle can be used as an extension of the vehicle floor when the side gate is open, thereby preventing vehicle tilting, shaking, etc., and improving safety. can be obtained. This exhibition vehicle has a box-shaped body when the roof and side gates are closed, and it is possible to practice playing music inside, so it is particularly suitable for uses such as music performances.
