Description

[Detailed Description of the Invention] The present invention relates to a simple cargo handling device, and more particularly to a simple cargo handling device suitable for installation on the loading platform of a small vehicle such as a light four-wheel vehicle.

As is well known, there are many cargo handling devices in practical use in which running wheels of cargo hoisting means run on the left and right sides of the lower surface of an I-shaped beam. For example, Jikko 57
−32055, Utility Model 52-77168, Utility Model 57-11191,
etc.

However, in the case of this I-beam, if you try to expand or contract the I-beam, you will need an I-beam holder with a special cross section. It is conceivable to insert the I-beam into a holder so that it can slide freely, but if the I-beam is placed in a box-tube shape, it will tend to wobble in the left and right direction, and the I-beam will not move smoothly in and out when expanding and contracting. is assumed. Therefore, Jikko 46-
As seen in 22341, a box-tube-shaped cargo handling mechanism whose four sides (left, right, top, and bottom) are closed is slidably disposed inside a box-tube-shaped holding body whose four sides (left, right, top, and bottom) are closed. A device equipped with a means for hoisting up luggage is in practical use.

According to this, the cargo handling mechanism is firmly guided by the holding body during expansion and contraction, so that it does not wobble left and right during the expansion and contraction operations. However, in the case of this conventional technology,
Both the cargo handling mechanism and its holder are box-tube-shaped with the left, right, top, and bottom sides completely closed, so the load hoisting means attached to the cargo handling mechanism is carried out in the longitudinal direction within the cargo handling mechanism because the chain or rope descends downward. It cannot be slid. Therefore, the cargo hoisting means can only be moved to an expanded and contracted position together with the cargo handling mechanism sliding within the holder, and the range of cargo handling is limited.

The present invention was devised in view of the above-mentioned points, and its gist is that a single pillar 4 stands up at the back of the loading platform 3 of a small vehicle 2 such as a light four-wheeler, and a bifurcated pillar 4 is installed in front of the loading platform 3. A cargo handling mechanism holder 7 is assembled to two pillars 5 and 6 that stand upright.
A cargo handling mechanism 19 formed to be longer than the length of the cargo handling mechanism holder 7 is slidably disposed inside the cargo handling mechanism 19, and a manual cargo hoisting means 20 is disposed in this cargo handling mechanism 19. In the simple cargo handling device;
B, C, and D are formed into a closed box-tube shape, and the other portions are cut out at the center of the lower surface D along the longitudinal direction. Among the four surfaces F, G, H, and K on the left, right, top, and bottom that can be in sliding contact with the inner surface of the holding body 7, the lower surface K
The center is notched along the longitudinal direction, and the left and right lower surface portions Q and R located on the left and right sides of the notch groove L in the center of the lower surface are used as the load hoisting means 20.
This is a simple cargo handling device characterized by being configured as a running guide surface for wheels M and N provided on the left and right sides of the vehicle. The cargo handling mechanism is firmly guided during its expansion and contraction operations, and its running performance is smooth.The cargo hoisting means arranged on the cargo handling mechanism also ensures that the cargo handling mechanism does not touch the holding body. To provide a simple cargo handling device which is movable along its longitudinal direction regardless of its position and has a wide cargo handling range.

Next, a first embodiment of the present invention will be described in detail with reference to the accompanying drawings FIGS. 1 to 5.

In the figure, 1 indicates the main body of the simple cargo handling device. This main body 1 is constructed so as to stand on three pillars on the installation surface in order to reduce the overall weight as much as possible.
One of the three pillars mentioned above is a single pillar 4 that stands up at the back when installed on the cargo bed 3 of the small car 2, and the other two are two pillars 5 that stand up in a bifurcated shape at the front. , 6. These three pillars support the cargo handling mechanism holder 7 so that it can be disassembled and assembled. In this case, the cargo handling mechanism holder 7 has a box-cylindrical shape in which the rear end of the cargo handling mechanism holder 7 is received by the pillar 4, with the left, right, top, and bottom drawings A, B, C, and D all closed. However, in other parts, a notch groove E is formed in the center of the lower surface D along the longitudinal direction.
A cradle 10 is formed at the top of the single pillar 4 with a fitting hole 9 for fitting with a fitting shaft 8 protruding from the lower surface D of one end of the cargo handling mechanism holder 7. is fixed.

Also, on the top of one of the two pillars and the other 6, there is a third
As shown in the figure, receiving plates 11, 11 are provided protrudingly, and these receiving plates 11, 11 are attached to the cargo handling mechanism holder 7.
The lower surface D of the other end is supported. then 12,1
Reference numeral 2 denotes bolt insertion holes formed at the ends of the two pillars. These bolt insertion holes 12, 12 are formed for inserting bolts 13 for fixing the upper parts of one and the other pillars 5, 6. Reference numeral 14 denotes a protrusion projecting from the upper surface of the other end of the cargo handling mechanism holder 7, and the protrusion 14 has a bolt insertion hole 15 formed therein. That is, when inserting the bolt 13 into the bolt insertion holes 12, 12 in order to fix the upper parts of one and the other pillars 5, 6, the bolt 13 is inserted through the bolt insertion hole 15 formed on the projection 14, and the nut 13a is inserted.
By fixing them, it is possible to firmly fix the cargo handling mechanism holder 7 and the upper parts of the pillars 5 and 6 on one side and the other side.

In this way, the upper parts of the two pillars 5 and 6 are firmly fixed while supporting the other end of the cargo handling mechanism holder 7. Since these two pillars are formed in a bifurcated shape that widens downward as described above, it is necessary to prevent them from expanding downward when weight is applied. Various means can be considered as the above-mentioned means, but in this embodiment, an example in which a wire 16 is provided is shown.

That is, rings 17, 17 are fixed near the lower ends of one and the other pillars 5, 6, and these rings 1
In this example, hooks 18 and 18 fixed to both sides of the wire 16 are hooked to the wires 7 and 17, and the wire 16 is disposed between one and the other pillars. In this way 1
A cargo handling mechanism body 19 is slidably disposed inside the cargo handling mechanism holder 7 supported by the main pillar 4 and the two pillars 5 and 6. The cargo handling mechanism body 19 has four surfaces F, G, H, and K (left, right, top, and bottom) that can slide into contact with the inner surface of the cargo handling mechanism holder 7, and the center of the bottom surface K is cut out as a notch groove L in the longitudinal direction. ing. That is, the notch groove E and the notch groove L communicate with each other. The total length thereof is longer than the total length of the cargo handling mechanism holder 7. In this embodiment, an example is shown in which the length is approximately 1.5 times that of the cargo handling mechanism holder 7.

Reference numeral 20 denotes a load hoisting means disposed within the load handling mechanism 19 so as to be able to move back and forth. In order to reduce the weight of the entire device, the load hoisting means 20 is a manual load hoisting means without using an electric motor or the like, and in this embodiment, a well-known chain block type hoisting mechanism is shown as the hoisting mechanism. That is, the hook 2 is attached to the tip of the wire rope 22 by manually rotating the chain 21.
3 can be moved up and down. In this case, the left and right wheels M and N of the cargo hoisting means 20 are configured to run on the left and right lower surfaces Q and R, which are located in the cutout groove L of the lower surface K of the cargo handling mechanism 19, as travel guide surfaces.

Next, 24 is an outrigger connected to the vicinity of the lower end of the columns 5 and 6, and is used to firmly support the columns 5 and 6 on the ground when installed on the loading platform 3 and used. This outrigger 24 is provided with a spiral height adjustment means 25, and
To keep it out of the way when not in use,
It is configured so that it can be rotated upward and stored.

The size of the main body 1 formed as described above is determined depending on the size of the place where it is installed. That is,
When installed and used on the loading platform 3 of a small automobile 2, the length l of the cargo handling mechanism holder 7 should not be too long, but should be, for example, 2/3 or less of the length of the loading platform 3.

Next, the operation will be explained based on the above embodiment.

Since the simple cargo handling device of the present invention is constructed as described above, it is suitable for use by being installed on the loading platform 3 of a ready-made small automobile 2. That is, as shown in FIG. 5, the assembled main body 1 is placed on the loading platform 3. For the above assembly, a fitting hole 9 formed in a pedestal 10 fixed to the top of one pillar 4 is fitted into a fitting hole 9 formed on the lower surface D of one end of the cargo handling mechanism holder 7. At the same time as fitting the mating shaft 8, one of the two pillars 5
The other end 6 catches and supports the other end of the cargo handling mechanism holder 7, and then the bolt 13 is passed through the bolt insertion holes 12, 15, 12. Then, the wire 16 is hooked to rings 17, 17 attached near the lower ends of one and the other pillars 5, 6 to prevent it from expanding downwards between the two pillars 5, 6. When installing on the loading platform 3, one pillar 4 standing at the back of the loading platform 3 is installed with a slight distance between the rear end of the loading platform 3. In the example shown in FIG. 5, the distance between one pillar 4 and the rear end of the loading platform is approximately 1/3 of the total length l of the cargo handling mechanism holder 7.

When the main body 1 is installed in this manner, the two pillars 5 and 6 are positioned completely in front of the loading platform 3. And luggage 26 outside the small car 2
When lifting the cargo, the cargo handling mechanism 19 and the hoisting means 20 disposed within the cargo handling mechanism 19 are moved so that the hook 23 is positioned directly above the cargo 26. At this time, the cargo handling mechanism 19 is slidably disposed within the cargo handling mechanism holder 7, and since the cargo handling mechanism 19 is formed longer than the cargo handling mechanism holder 7, the end of the cargo handling mechanism 19 The part can be made to protrude outward. For that reason, Fuku23
can be positioned directly above the luggage 26 placed outside the small car 2.

Moreover, the left and right upper and lower surfaces A, B,
Since the left and right upper and lower surfaces F, G, H, and K of the cargo handling mechanism 19 are in sliding contact with the inner surfaces of C and D, the cargo handling mechanism 19
The expansion and contraction movements of the body become stable and smooth. After the hook 23 is positioned directly above the baggage 26 in this way, the chain 21 is turned to extend the wire 22 and the hook 23 is hooked to the baggage 26.

Next, the chain 21 is turned in the opposite direction to lift the load 26 upward. In this way, luggage 2
6 is lifted upward, the cargo handling mechanism 19 and the cargo hoisting means 20 are moved to the left in FIG. 5 and carried onto the cargo platform 3. In this way, notch grooves E are also formed on the lower surface D of the cargo handling mechanism holder 7, except for the rear end, and notch grooves L are also formed on the lower surface K of the cargo handling mechanism body 19, which is useful for hoisting up cargo. Means 2
Since the wheels M and N of 0 are configured to use the left and right lower surfaces Q and R as travel guides, the load hoisting means 20 can be moved over substantially the entire length of the cargo handling mechanism holder 7 and the cargo handling mechanism body 19, Wide range of cargo handling.

After the cargo 26 is carried to a predetermined position, the chain 21 is turned again to lower the cargo 26 that has been lifted upward onto the loading platform. In this way, the luggage 26
When lifting the outrigger 24, which is connected to the lower ends of the two pillars 5 and 6, is rotated as shown by the arrow 27 in FIG.
If the main body 1 is landed on the top 8, the main body 1 can be kept stable, and the cargo 26 can be lifted safely.

After the cargo loaded onto the platform 3 in this manner has been transported to the destination location, the cargo is carried out by the same operation as when it was carried in. If there is no suitable cargo handling equipment at the location where the cargo is unloaded, use the cargo platform 3.
The main body 1 installed on the top can be disassembled and assembled and used at the place of use.

Since the cargo handling mechanism body 19 is formed longer than the cargo handling mechanism holder 7, it can be made to protrude largely outside the cargo platform when loading or unloading cargo, but when not in use, it If it is moved to the back of the loading platform as shown by the one-dot chain line, it can be prevented from protruding from the loading platform. For this reason, even in the case of a canopy car, for example, the rear door can be easily closed.

The main body 1 is constructed to stand on the loading platform 3 with three pillars, and the sliding of the cargo handling mechanism 19 and the load hoisting means 20 are performed manually. , the overall weight could be made light and compact. Therefore, it is particularly suitable for installation on a small vehicle, since it is possible to carry more luggage due to the reduced weight and size. Also, one end of the cargo handling mechanism holder 7 is 1
Since it is supported at one point by the main pillar 4, the other side can be easily rotated around one pillar 4 as shown in Fig. 6, making it easy to lift and suspend cargo. I can do it.

Next, a second embodiment of the present invention will be described with reference to FIG. 7 of the accompanying drawings.

In this example, the substantial structure, purpose, and effect are the same as those of the first embodiment, and the same parts are given the same reference numerals and the explanation thereof will be omitted.

This example shows an example in which extension legs 50 are attached to the lower ends of two pillars 5 and 6 that stand in front of the loading platform. The extension leg 50 is normally 2
The main pillars 5 and 6 are separated, and when used, the length of the two pillars 5 and 6 is extended and the two pillars 5 and 6 are installed so that they can stand directly on the ground. . There are various ways to connect the two pillars 5, 6 and the extension leg 50, but in the example shown in the figure, the two pillars are fitted into the extension leg 50 and the shaft pin 51 is inserted to prevent it from coming out. It shows.

Next, a third embodiment will be described with reference to FIG. 8 of the accompanying drawings.

In this example, the other end 6 of the cargo handling mechanism holder 7
An example is shown in which an auxiliary column 61 is connected to the 0 and an extension leg 50 is attached so that the auxiliary column 61 can be placed directly on the ground during use.

By doing so, the main body 1 can be made even more stable.

As detailed above, according to the present invention, the cargo handling mechanism is slidably guided to the cargo handling mechanism holder held on the loading platform of the vehicle, and when it expands and contracts, the guiding performance is smooth and , the load hoisting means can be moved from one end to the other along its entire length. That is, no matter what position the cargo handling mechanism is in with respect to its holder, the load hoisting means can be moved from one end of the cargo handling mechanism to the other. Therefore, the cargo handling range is wide.
