Description

[Detailed Description of the Invention] When a transport vehicle is to be stored along a wall such as a corner in a warehouse, a transport vehicle equipped with casters at both ends of the traveling trolley and a large-diameter fixed wheel in the center is not suitable. The above is inoperable.

In addition, for transport vehicles that only have casters on the running trolley,
Even if the above-mentioned operation is possible, each caster changes its direction at any time when transporting the goods from outside the warehouse to a predetermined location within the warehouse, making the path undefined and transportation extremely difficult.

The present invention has been proposed in order to eliminate such drawbacks, and includes a pair of left and right groove-type guide frames with vertical pieces extending from both front and rear ends of a horizontal frame piece, suspended from the lower surface, and casters. A guide member slidably fitted across the horizontal pieces of the twin groove-type guide frames is attached to a frame body having fixed wheels for running mounted on the tip of the frame. It consists of a bundle frame arranged perpendicular to the body, and when the bundle frame is erected on one end side of the traveling trolley and the fixed wheels are brought into contact with the floor, the casters on the same end side are placed above the floor surface. This relates to a transport vehicle characterized in that it is configured to be separated from the vehicle.

Since the transport vehicle according to the present invention is configured as described above, the bundle frame is normally suspended from the groove-shaped guide frame suspended from the lower surface of the traveling vehicle via the guide member. Stored.

When the transport vehicle is transported to a warehouse or the like, when the bundle frame is pulled out toward one end of the traveling vehicle, the guide member disposed on the bundle frame will move along the horizontal frame pieces of the pair of left and right groove-shaped guide frames. The bundle frame is easily pulled out.

When the guide member collides with the end vertical piece of the groove-shaped guide frame, the bundle frame is rotated upward using the colliding portion as a fulcrum, and the traveling fixed wheel at the tip of the surrounding frame is brought into contact with the floor. The casters at one end of the traveling cart are separated above the floor surface, and the fixed wheels for traveling and the casters at the other end are in contact with the floor and roll on the same floor, so that the transport vehicle can move as required. It can be easily transported in any direction.

When the transport vehicle is transported to a corner of the warehouse or near a wall, the bundle frame is laid down in the opposite direction, and the vehicle travels using its guide member and the horizontal pieces of the two groove-shaped guide frames as guides. By pushing the trolley downward and storing it in a suspended state at the bottom of the groove-shaped guide frame, the traveling trolley can be moved only by casters, so that the traveling trolley can be maneuvered along the wall surface. It can store transport vehicles.

As described above, according to the present invention, a transport vehicle can be efficiently stored along a predetermined wall surface with a simple mechanism.

The present invention will be described below with reference to the illustrated embodiments.

Reference numeral 1 denotes a traveling trolley, and casters 2 are attached to the front and rear thereof.

In the figure, numeral 3 denotes a gate-shaped front and rear frame detachably attached to both the front and rear ends of the traveling truck 1, and 3a denotes a horizontal frame horizontally suspended between both side pieces 3b of the surrounding frame 3 in the form of a ladder.

On the lower surface of the traveling truck 1, vertical frame pieces 4b and 4c are extended from both front and rear ends of the horizontal frame piece 4a. 4c
are suspended through.

Reference numeral 5 denotes a gate-shaped handle frame on which a running fixed wheel 6 is mounted via an axle 7, and a gate-shaped guide piece 8 is bridged between the tips of both left and right leg pieces 5a, 5a. Both vertical pieces 8a, 8a are fixed to each leg piece 5a, and
A horizontal piece 8b connecting the vertical pieces 8a, 8a is slidably mounted on the horizontal frame piece 4a of the groove-shaped guide frame 4.

Further, the proximal end sides of the leg pieces 5a, 5a engage with a horizontal support piece 4d that is horizontally suspended between the two horizontal frame pieces 4a.
When viewed from the side, an inverted engagement piece 5b with an open front is suspended horizontally.

Therefore, the handle frame 5 is normally stored on the lower surface of the traveling carriage 1 while being suspended on the lower surface of the groove-shaped guide frame 4 in parallel to the lower surface of the groove-shaped guide frame 4 via the gate-shaped guide piece 8 and the engagement piece 5b. ing.

(See Figure 2) Since the present invention is constructed as described above, when carrying the carrier into a warehouse, the handle frame 5 is connected to the horizontal piece 8b of the guide piece 8 and the groove as shown in Figure 2. By sliding the horizontal frame piece 4a of the mold guide frame 4 as a guide, the traveling carriage 1 is pulled horizontally outward from one end, and when the horizontal piece 8b collides with the rear vertical frame piece 4c, the arrow shown in FIG. As shown in FIG. 4, the handle frame 5 is rotated upward using the collision portion as a fulcrum, and as shown in FIG. 4 and FIG.
The rear end side caster 2 is separated above the floor 9, and the other end side caster 2 and the traveling fixed wheels 6 are in contact with the floor.

At this time, the leg piece 5 of the handle frame 5 is
It is preferable to lock a to the rear frame 3.

In this state, the transport vehicle is carried into the warehouse near a predetermined wall surface, and then the handle frame 5 is retracted to the bottom surface of the groove-shaped guide frame 4 of the traveling trolley 1 by reversing the previous operation, and each of the front and rear casters 2 is The running cart 1 that is in contact with the floor is operated and stored along the wall surface.

Although the present invention has been described with reference to one or more embodiments, the present invention is of course not limited to such embodiments, and can be modified in various designs without departing from the spirit of the invention. be.
