Description

  The present invention relates to a handcart of a type that lifts and pushes a rear handle with a wheel as a fulcrum, and is particularly used for transporting a beehive for beekeeping.

  Conventionally, a hand-held single-wheel carriage has a parallel frame portion at the middle portion, a connecting frame portion that rises forward in front of the parallel frame portion, and a front end that closes in a substantially U-shape, and a rear frame that rises behind the parallel frame portion. A pair of right and left hand handles extending from the horizontal frame portion between the parallel frame portions below the connecting frame portion, a wheel support portion for supporting a single wheel, a rear portion of the parallel frame portion, and a hand handle A substantially triangular leg portion fixed between the intermediate portion and a parallel frame portion, a connecting frame portion, and a dish-shaped cargo bed placed on the front portion of the hand handle. (Patent Document 1).

Japanese Patent Laid-Open No. 10-273052

The conventional hand-held transport vehicle is used for transporting relatively large heavy objects or large quantities of luggage that are difficult to hold. This is a cumbersome work that requires careful loading and unloading on the loading platform, and it is necessary to securely fix it on the loading platform in order to avoid the danger of falling, and the transportation work efficiency is poor and rapid transportation is difficult.
Therefore, the present invention provides a hand cart for a honeycomb box that can be loaded and unloaded without having to hold the nest box during transportation, can be securely fixed on the carrier during transportation, and improves the efficiency of the transportation work. Objective.

In order to solve the above-mentioned problems, a hand truck for a honey beehive according to the present invention supports a wheel 3 on the front side, a pair of handles 4 extending in the left and right directions on the rear side, and a beehive for a beekeeping in the middle. The frame body 2 to be gripped is provided, the handle 4 is held, and the rear part is lifted and pushed with the wheel 3 as a fulcrum to carry the nest box B. The frame 2 is pivotally supported by a horizontal pivot 11 at the front and rear in the horizontal direction , the handle 4 extends rearward from one end, and the other end can approach and separate from each other by raising and lowering the handle 4. A pair of intersecting frames 10, 10 and a guide member such as a slide guide 12 that is interposed between these intersecting frames 10 and that can extend and retract in the horizontal direction to guide the mutual approach and separation. Other end of the cross frame 10, approach each other with the raising and lowering of the handle 4, apart from gripping the hives B, and includes a gripping arm 17 to be released.

  According to the present invention, when carrying a beehive for beekeeping, an operator can lift and lower the nest box without holding it, and it can be fixed securely without moving easily during carrying, Work can be performed quickly and safely.

It is a perspective view of the hand cart of the present invention. It is a front view of the handcart of FIG. It is a side view of the handcart of FIG. It is a top view of the handcart of FIG. It is explanatory drawing which shows a motion of an intersection frame. It is explanatory drawing which shows the use condition of the handcart of FIG.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
1 to 4, a hand truck 1 for a beekeeping beehive B according to the present invention includes a frame 2 that supports a wheel 3 at a front portion, holds the nest box B at a rear portion thereof, and a handle 4 extends backward. It has.

  The frame body 2 includes a wheel support portion 5 and a cargo handling portion 6. The wheel support part 5 includes a bracket plate 7 formed by folding back a pair of left and right brackets 7a, 7a, which support the horizontal axis of the wheel 3 via a bearing, in a substantially U-shaped cross section, and a bracket plate 7 and an attachment frame 8 fixed to the lower surface of the upper plate 7b.

Load gripping portion 6 constituting the frame body, the lateral direction intermediate portion is pivotally attached rotatably to one another by the front and rear horizontal pivot 11, 11, extending from one end to the rear wheel 4, respectively, around the pivot 11 a stretchable pair of cross frames 10, 10 of the left-right width, comprising a slide guide 12 which bind with back and forth between the other end of the cross frame 10, 10.

  The cross frame 10 includes a pair of link rods 13 and 13 opposed to the front and rear, horizontal rods 14 and 14 connecting the upper ends of the link rods 13 and 13, and a support rod 15 extending downward from the lower end of the front link rod 13. A leg rod 16 extending downward from the rear link rod 13, a gripping arm 17 extending between the support rod 15 and the leg rod 16, and a lower end extending downward from a joint portion between the rear link rod 13 and the support rod 15. And a connecting rod 18 to which the handle 4 is coupled. The leg rod 16 supports the frame body 2 together with the wheels 3 so that the horizontal rod 14 and the gripping arm 17 are horizontal at the ground contact position. The gripping arm 17 is formed of a steel plate material having both ends formed wide, and the inner side so as to be hooked on the main body 17a along the side surfaces of the support rod 15 and the leg rod 16 and the lid receiver B1 protruding to the side of the hive B. And a holding portion 17c that extends vertically downward so as to come into contact with the side surface of the nest box B.

  The front slide guide 12 has a guide pipe 12a formed of a square pipe pivotally attached to a mounting plate 19 whose base end is fixed to the link rod 13 and the support rod 15 of one of the cross frames 10; The base end is pivotally attached to the support rod 15 of the other cross frame 10 so as to be rotatable in the vertical direction, and includes a slide bar 12b inserted in and out of the guide pipe 12a. The rear slide guide 12 includes a guide pipe 12a formed of a square pipe pivotally attached to a mounting plate 20 whose base end is fixed to the link rod 13 and the leg rod 16 of the one cross frame 10 so as to be rotatable in the vertical direction. And a slide bar 12b pivotally attached to the leg rod 16 of the other cross frame 10 so as to be rotatable in the vertical direction and inserted into the guide pipe 12a so as to freely enter and exit. The slide guide 12 joins the intersecting frames 10 and 10 so as to extend and contract in order to guide the movement of the gripping arms 17 and 17 in the horizontal direction below the pivot 11 of the intersecting frames 10 and 10.

  When the nest box B is transported by the hand cart 1, the grip arm 17 is lifted while pushing the handle 4 inwardly with the wheel 3 as a fulcrum while the gap between the grip arms 17 and 17 is open in the vicinity of the nest box B placed on the ground. , 17 so that the nest box B is received, and the handle 4 is lowered. Here, once the handle 4 is lowered and then the handle 4 is lifted again, as shown in FIG. 5, the cross frames 10 and 10 rotate around the pivot axes 11 and 11 to narrow the space between the gripping arms 17 and 17, The gripping arm 17 is hung on the lower part of the lid receiver B1 of the nest box B, and the holding part 17c is pressed against the side surface, so that the nest box B can be held between the gripping arms 17 and 17. As shown in FIG. 6, the handle 4 can be pushed and moved while being lifted. When the handle 4 is lowered and lowered at the moving destination, the intersecting frames 10 and 10 of the frame 2 are inverted around the pivots 11 and 11 so that the grip arms 17 and 17 are opened, and the nest box is placed with the leg rod 16 placed on the ground. B can be released.
