Description

[Detailed Description of the Invention] This invention relates to a crane device for a towed vehicle that is attached to a towing device for the towed vehicle.

Generally, in a trailer-type towed vehicle, cargo is loaded or unloaded using an externally installed crane or manual labor. However, when loading or unloading heavy objects, a crane is always required, resulting in the inconvenience that loading or unloading work can only be carried out at the location where the crane is installed. Furthermore, even if the items are lightweight, it is extremely troublesome to manually load or unload a large number of items.

This idea was devised in view of the above-mentioned circumstances, and its purpose was to attach a telescopic support shaft to the towing device of the towed vehicle, and to attach the support shaft at the tip of the support shaft in a direction substantially perpendicular to the longitudinal direction. A jib is rotatably and removably attached, a pulley is disposed at the tip of the jib, a winch is disposed at the base of the jib, and the wire of the winch is installed on the pulley. In other words, in order to make the most effective use of the space of the towed vehicle, the towing device is equipped with a spindle that can be retracted and retracted, as well as a removable jib and winch, making it lightweight and lightweight in any location. An object of the present invention is to provide a crane device for a towed vehicle capable of loading or unloading cargo.

This invention will be explained in detail below based on the accompanying drawings.

FIG. 1 is a side view showing a crane device for a towed vehicle according to this invention. In the drawing, 1 is a frame that can be moved by wheels 2, and on the frame 1 is a rectangular box with an opening at the top. A baggage storage section 3 of the shape of the shape is provided. In addition, a traction device 4 having a spire-shaped tip is pivotally attached to the front part of the frame 1 so that it can be raised and lowered by brackets 5 and 6 attached to both ends of the front part of the frame 1 (as shown in FIG. 3). ). Traction device 4
Support protrusions 7 and 8 are provided on both central edges of the baggage storage unit 3 to protrude upward, and support brackets 9 and 10 on which the support protrusions 7 and 8 can be engaged are attached to the front side wall 3a of the baggage storage section 3. and support means are formed by the support projections 7, 8 and the support brackets 9, 10 (as shown in FIG. 3).

Cylindrical bodies 11 and 12 are fixed to the central upper surface of the traction device 4 along the longitudinal direction.
A pole 13, which is a supporting shaft that is slidable in the cylinder of the traction device 2 and thereby is extendable and retractable in the longitudinal direction of the traction device 4, is attached. The pole 13 can be fixed in the contracted state and in the extended state by fixing pins 14 and 15, which extend through the cylinders 12 and 11, respectively. Further, as shown in FIG. 4, a rotary shaft 15' is attached to the tip of the pole 13 so as to be rotatable about the longitudinal direction of the pole 13 as a central axis. A cylindrical fitting 16' is fixed to the tip of the rotating shaft 15' in a direction substantially perpendicular to the axial direction of the rotating shaft 15', and a fixing pin 17' is fixed to the fitting 16' substantially perpendicular to the cylindrical axis. It is installed so that it can be inserted and removed in the direction. A rod-shaped jib 16 is removably inserted into the cylinder of the fixture 16', and is fixed therethrough by a fixing pin 17'. A pulley 17 is attached to the tip of the jib 16, and a hand-wound winch 18 is attached to the base of the jib 16, which is operated by a handle 18'. A wire 19 of the winch 18 is installed via a pulley 17, and a hook 20 is attached to the tip of the wire 19. When not in use, the hook 20 is locked to a ring 20' formed on the side of the jib 16. There is.

Since the crane device according to this invention is as described above, when loading cargo onto the towed vehicle, the towing device 4 is attached to the support protrusions 7, 8 and the support brackets 9, 10 as shown in FIG. is fixed with a pin or the like to raise it up, and then slide the pole 13 to extend it and fix it with the fixing pin 15, attach the jib 16, and then open the winch 18 and jib 16 by operating the handle 18'. It is possible to easily load cargo into the towed vehicle and unload it from the towed vehicle by manually rotating the towed vehicle.

In addition, when connecting to a towing vehicle by the towing device 4 without using a crane device, the pole 13 is slid to the retracted state as shown in FIG.
It is fixed by a fixing pin 14, and further by a support protrusion 7,
8 and the support brackets 9 and 10 to place the traction device 4 in a down position, and the jib 16
is an implant attached to the top of the housing 3 or to the side of the housing 3 by means of a cloth band 21 attached above the housing 3 as shown in FIG. 5 or FIGS. 6 to 8. By hanging the shaft 22, screw handle 23, and ring portion 20' on the hook 24 and storing them on the same side, the entire crane device can be stored compactly so as not to become an obstacle to towing. It is possible.

Therefore, since the crane device according to this invention can be stored compactly, it can be installed on a towed vehicle without narrowing the cargo storage space of the towed vehicle, and it can be used for loading or unloading cargo. It has the advantage of being able to be unloaded at any location, and its utility value is remarkable.
