Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a multipurpose handcart for conveying containers, transportation, shopping baskets, and goods.

Conventionally, for example, as shown in FIG.
A triangular protrusion 4 is formed on the upper part of the vertical rod 3 by connecting them, a wheel 5 is pivotally attached to the lower end, and a semicircular part 6 with a foothold 6a at the rear is formed at the lower part of both vertical rods 3. Suspended container barrows connected by support rods 7 are known. When using this handcart, when transporting a plastic container placed on the ground, tilt the vertical rod 3 forward, engage the triangular protrusion 4 with both handles 9 of the plastic container, and place the footrest 6a on the foot. and press down on handle 1 at the same time.
By pushing down, the plastic container can be easily lifted using the wheel 5 as a fulcrum and the triangular protrusion 4 acting as a point of action, and by holding the vertical rod 3 vertically, the plastic container is suspended.

However, such handcarts are often unable or extremely difficult to transport shopping baskets or other items other than plastic containers. Moreover, plastic containers come in various sizes, and it is virtually impossible to prepare several handcarts depending on their diameters. Therefore, there is a need for a multi-purpose handcart that can transport various goods and objects for home and business use.

In view of this, the present invention has a flexible arm for transporting all containers of various diameters, and is configured to fold up so as not to take up space when the flexible arm is not in use. The main purpose is to propose this type of wheelbarrow that has solved the problem.

An embodiment of the present invention will be described in detail below with reference to the drawings.

2 and 3 are a left side view and a front view showing an example of the present invention. 10 indicates the axle, axle 1
A rotatably fitted wheel 11 is attached to both ends of the 0. The free end of a main rod 12, which is bent in a substantially U-shape and extended in the vertical direction, is joined to the axle 10, and the upper part becomes a handle portion 12a. A tube body 14 is fitted on both sides of the main rod 12 at a substantially intermediate position, and the tube body 14 is locked to the main rod 12 with a screw 15. Two upper and lower horizontal shafts 16 and 17 are integrated into the tube body 14, and the horizontal shafts 16 and 17 move together as the tube body 14 moves up and down. On both sides of the horizontal axis 16 are provided articulated arms 18 for gripping or supporting the container. The articulated arm 18 can have at least one joint (as shown). joint 1
9, the second arm 18b can freely rotate in the horizontal direction relative to the first arm 18a, but can be fixed by tightening a screw 19a forming the joint 19.
A container locking portion 18c is provided at the free end of the second arm 18b. The locking portion 18c may be a triangular pyramid-shaped metal fitting instead of the U-shaped metal fitting as shown in the figure.

The multi-jointed arm 18 is configured to be folded down when not in use so as not to interfere with the transportation of other articles. That is, as shown in FIG. 4, the left and right first arms 18a
A pin 21 is provided to protrude from the inside thereof, and the pin 21 is fitted into an arcuate groove 22a of an arcuate plate 22 that rotates about the horizontal axis 17. A horizontal groove 22b is continuously formed above the arcuate groove 22a. When the multi-joint arm 18 is used, the multi-joint arm 18 maintains a substantially horizontal state because the weight of the arm 18 is added and the pin 21 is engaged with the horizontal groove 22b of the arcuate groove 22a. However, pin 21 and horizontal groove 2
2b, by pressing the pusher 24 protruding from the horizontal shaft 17 in the direction of arrow A in FIG.
The pin 21 moves inside, and the multi-jointed arm 18 remains in a substantially hanging position as shown in FIG. 4B. When using the multi-joint arm 18 again or transporting it to a plastic container, the push metal fitting 25 protruding from the horizontal shaft 16 is pressed in the direction of arrow B in FIG. If it rotates counterclockwise around the shaft 16 and stops pressing the pusher when the pin 21 and the horizontal groove 22b engage, it will return to its original position (see Figure 2). .
In this case, by simply pressing the pusher 25 in the direction of arrow B, the pin 21 and the arcuate groove 22a are engaged, so that the horizontal axis
It can be rotated counterclockwise around 7. As shown in FIG. 5, when the pin 21 reaches the horizontal groove 22b, the center of gravity of the arm 18 itself is on the right side of the horizontal axis 17 in FIG. engages the end and thus pin 2
1 and the horizontal groove 22b are reliably engaged.

In FIGS. 2 and 3, reference numeral 31 indicates a housing formed into a thin line, and the lower end of the housing 31 is a stone protrusion 3 formed protruding forward from the axle 10 (to the right in FIG. 2).
2 and a basket support 33, and its upper end is locked by a bendable hook 33 that engages with the horizontal shaft 16. As shown in FIG. 6, the hook 33 is composed of a ring 33a fitted to a wire 31a at the upper end of the casing 31 and a hook portion 33b. The basket 33 can be removed by releasing the engagement between the hook portion 33b and the horizontal shaft 16.

FIG. 7 is a partially omitted front view with the housing 31 removed. Reference numeral 35 indicates an article mounting table whose left and right sides are pivotally supported by L-shaped metal fittings 36, and this size is a thin linear shape whose width is narrower than the main rod 12 and whose vertical width approximately corresponds to the distance between the axle 10 and the horizontal axis 16. belongs to. When not in use, the left and right hooks 37 are engaged with the horizontal shaft 16 to hold the article vertically; however, when transporting the article, the hooks 37 are released and the stone protrusion 37 is laid down horizontally.
I'll put it on. Therefore, articles of various sizes can be placed on the mounting table 35.

Note that the multi-jointed arm 18 may have two or more joints.

As described above, according to the present invention, there are first and second horizontal shafts separated from each other that slide vertically on the main rod, and a multi-jointed arm that is rotatable about the first horizontal shaft. , an arcuate plate provided to rotate around a second horizontal axis, the arcuate plate is provided with an arcuate groove and a horizontal groove continuous thereto, a pin is provided in the multi-jointed arm, and the pin is attached to the arcuate groove. and horizontal grooves, and the working side of the multi-jointed arm is configured to be rotatable in the horizontal direction so as to engage containers of different sizes. The position of the multi-jointed arm can be adjusted up and down by sliding the shaft up and down, and the interval between the multi-jointed arms can be adjusted according to the size of containers, etc. with different diameters or widths. This eliminates the inconvenience of having to specify the size of the container.

Further, according to the present invention, first and second horizontal shafts separated from each other slide vertically on the main rod, a multi-jointed arm provided to rotate about the first horizontal shaft, and a second horizontal shaft. The arc plate is provided with an arc groove and a horizontal groove continuous to the arc plate, and a pin is provided in the multi-jointed arm, and the pin is attached to the arc groove and the horizontal groove. The upper end of the article mounting table, which rotates around the position of the axle connected to the main rod, is set to coincide with the first horizontal axis, and the Since we have provided a hook that locks on the horizontal axis, it is possible to release the hook and horizontalize the product loading table so that many packaged items can be loaded and transported, but this is also necessary when transporting items larger than the loading platform. By moving the first and second horizontal axes to certain locations and by stretching a rope or the like between the multi-jointed arm and the mounting table, transportation can be ensured, and the multi-jointed arm can also be folded down. Since larger items can also be transported, it is possible to provide a handcart for transporting various types of items that are not limited to specific items.
