Description

[Detailed description of the invention]

[0001]

[Industrial applications]

 The present invention relates to a weeding cart that can be conveniently used for weeding, such as extracting weeds from a garden.

[0002]

[Prior art]

 Conventionally, as a work cart for agriculture such as weeding work in a field or planting seedlings, a stool is provided at one end of a trolley that moves by wheels, and the worker sits on the stool and lifts the ground with his feet. Work carts that move while kicking are known, for example, from Japanese Utility Model Laid-Open No. 63-127308, Japanese Utility Model Laid-Open No. 2-1907, and the like.

[0003]

[Issues to be solved by the invention]

 The agricultural work carts described above are arranged in the grooves between the ridges, and work on the ridge surface, which is one step higher than the grooves, while moving along the grooves. Even when sitting on a trolley, it is possible to work with a hand holding a tool such as a small scythe close enough to the surface of the ridge, and the worker leans forward too deep while sitting on the stool of the bogie. Instead, the work can be continued in a relatively comfortable posture.

[0004] On the other hand, in an operation in which weeds are extracted from the garden, the grass grows on the same surface as the soles of the feet that support the worker's body. In order to approach the grassy ground, the hips and knees of the feet must be bent deeply into a bent position, and by maintaining such a cramped position for a long time, Weeding in the garden has traditionally been considered a difficult task because of the heavy strain on the legs and the increase in fatigue.

[0005] For such weeding work in the garden that requires labor, it is conceivable to use the agricultural trolley with a stool as described above. Since it grows in a low position on the same plane as the sole of the foot that supports the worker's body rather than a high position like a ridge, if the worker sits on a stool with a stool and works, As the waist rises, the hand holding the weeding tool must be extended to a lower position, resulting in a deeper leaning angle of the upper body, making it difficult to work and fatigue. Will increase. For this reason, there is a problem that agricultural stools can not be used for weeding work in the garden.

On the other hand, as a method for performing weeding work in the garden in a comfortable posture without taking a crouched posture in which the body is bent, a crawling state in which both knees and one arm are attached to the ground is used. The half-body can be supported almost level with the ground and the grass can be taken with one free hand, but this method always requires one arm to rest on the ground to support the body. Therefore, in this method, weeding is performed with only one hand, and there is a problem that it is not possible to use tools at the same time to remove the roots only by peeling off the upper part of the grass.

[0007] The present invention has a problem associated with the operation of extracting grass that grows at a lower position on the same plane as the position of the soles supporting the worker's body, such as the above-mentioned conventional garden weeding operation. In other words, instead of using a work method in which a cramped posture with a crouched body causes a burden on the legs and hips as in this kind of general work, the knees and the upper body can be moved with a movable cart. The purpose of this work is to provide a work cart that can be used with both hands for reliable weeding while supporting it in a relatively easy position with its upper body almost level with the ground.

[0008]

[Means for Solving the Problems]

 The weeding trolley of the present invention is a concrete weeding trolley for weeding while supporting the upper body and knees of a prone body, and is a horizontal trolley supported by wheels. In addition to the provision of a knee support mat on the rear surface of the bogie, the rear surface of the bogie has a rear edge supported by a pedestal of a predetermined height suitable for supporting a prone upper chest. It is characterized by having a breast support mat inclined in the direction.

The pedestal for the breast mat provided on the front surface of the trolley has a structure in which a plurality of foamable synthetic resin blocks are stacked and bundled together with a belt or the like, and the size of the worker's body is increased. It is preferable that the number of blocks is selected according to the above, so that the bogie supporting the chest can be adjusted to a height at which work can be easily performed. Further, the breast support mat may be provided on the pedestal via means capable of appropriately adjusting the inclination angle.

[0010]

[Embodiment of the invention]

 Next, the structure of the weeding trolley according to the present invention will be described with reference to the embodiment shown in the drawings. As shown in FIG. 1, this trolley was horizontally supported by front, rear, left and right wheels 2. A trolley 1 made of a wooden board of 40 cm in length and width, a soft knee mat 3 provided on the rear surface of the trolley 1, and a pedestal 4 projecting from the front surface of the trolley 1 with a predetermined height. It is basically composed of a soft breast support mat 5 provided at the same time.

The knee receiving mat 3 provided on the rear surface of the cart 1 is for supporting the feet and the waist by placing both knees of the worker, and has a size of about 40 × 20 cm in length and width, and is suitable. It is made of a sheet of foamable synthetic resin having cushioning properties, such as a thick polyurethane foam, and is fixed on the rear surface of the cart 1 in a horizontally long orientation. As shown in FIG. 2, the male type fastener 6a is attached to the back surface and the rear surface of the cart 1, and the belt-shaped female fastener 6b is also wound around the mat 3, so that when it gets dirty, it can be removed from the cart 1 and washed. As described above, it is preferable that the male and female double-sided fasteners 6a and 6b be attached and detached by bonding.

On the other hand, as shown in FIG. 3, a pedestal 4 for attaching a breast receiving mat 5 provided on a front surface of the trolley 1 is such that an operator places both knees on the knee receiving mat 3 as shown in FIG. When the lower body is in a prone position with the upper body tilted forward while supporting the legs and waist, with the ends of both hands extended to a position where the grass on the ground can be pulled out, the lower surface of the chest of the upper body is fixed from the ground It protrudes so as to be supported at the height position.

The pedestal 4 is formed by stacking a plurality of blocks 4a made of a foamable synthetic resin, which is light and easy to cut, such as polystyrene foam having a length and width of about 15 cm and a thickness of about 5 cm. 1, a block 4b inclined about 15 to 30 degrees in the rear direction is arranged, and each block 4a, 4b is vertically arranged by a belt 7 composed of a female hook-and-loop fastener 7b provided with a male hook-and-loop fastener 7a at one end. The height can be adjusted by selecting the number of blocks 4a according to the size of the worker's body, and the height can be adjusted. The pedestal 4 is detachably attached to the trolley 1 by adhering the belt 7 to the male surface fastener 7c previously attached to the front surface of the trolley 1.

The breast receiving mat 5 attached to the upper surface of the pedestal 4 is made of the same material and the same cushioning sheet made of the same material as the knee receiving mat 3, and a reinforcing plate 8 is provided on the back surface. The breast mat 5 is provided in a vertically long direction, and the rear edge 5a is inclined in the rearward direction of the carriage 1 when viewed from the side on the inclined block 4b at the upper end of the pedestal 4 via the reinforcing plate 8. It is fixed in a proper shape.

As shown in FIG. 2, when attaching the breast receiving mat 5 to the pedestal 4, male surface fasteners 9 a and 9 b are attached to both front and back surfaces of the reinforcing plate 8. Also, a female fastener 9c in the form of a belt is wound thereon, and the female fastener 9c of the breast support mat 5 is bonded to the male fastener 9a on the front surface of the reinforcing plate 8, and the male fastener 9b on the back surface of the reinforcing plate 8 is attached. Is adhered to the belt 7 made of the female surface fastener 7b on the upper surface of the pedestal 4, so that the breast receiving mat 5 can be removed from the reinforcing plate 8 and the pedestal 4 if necessary. It is preferable to remove and wash the contaminants when they become dirty, or to attach a mat or the like in place of the mat 5.

In the above embodiment, the knee receiving mat 3 and the pedestal 4 are detachably attached to the trolley 1 by the hook-and-loop fasteners 6 a, 6 b, 7 a, 7 b, 7 c. The base 4 and the base 4 are detachably attached to each other by the hook-and-loop fasteners 7b, 9a, 9b, and 9c. It may be configured such that the reinforcing plate 8 and the pedestal 4 are fixed together by an adhesive.

In the above embodiment, the pedestal 4 is formed by stacking a plurality of blocks 4a made of a foamable synthetic resin and a block 4b having an inclined surface. However, the pedestal 4 is not necessarily composed of a plurality of blocks. It is not limited to a stack of blocks, and the lower surface of the chest of the upper body, which is prone on the trolley 1, can be supported at a predetermined height position, and the height can be adjusted according to the worker's body. For example, a pillar having a predetermined height with a length adjusting means is protruded from the bogie 1 and the upper end of the pillar provides a cushion-like thick sheet. It may be configured such that a breast support mat is provided.

Further, in the above embodiment, the breast receiving mat 5 provided on the pedestal 4 is fixed at a predetermined angle in advance by bonding the mat to the block 4 b having an inclined upper surface at the upper end of the pedestal 4. For the receiving mat 5, for example, a plurality of blocks having different inclination angles are prepared in advance so that a block having a desired inclination angle can be freely selected according to the size of the worker's body. The breast support mat 5 may be connected to the pedestal 4 via a hinge whose angle can be adjusted, so that the inclination angle can be adjusted as appropriate.

When using the weeding cart according to the present invention, as shown in FIG. 3, the worker places both knees on the knee receiving mat 3 at the rear of the cart to support the feet and waist. At the same time, while supporting the upper body in a prone position with the upper body down on the chest support mat 5 at the front of the bogie, the arms are extended forward of the bogie 1 and the grass is extracted with both hands, and the grass at the predetermined position is extracted. After that, move forward as if kicking the trolley with your toes placed on the ground.

[0020]

[Effect of the invention]

 As described above, the weeding cart according to the present invention supports both the knees on the knee support mat 3 at the rear of the cart, thereby supporting the lower body of the feet and waist on the cart 1 and the prone position. The upper body, which has been tilted forward so as to assume a posture, can be stably supported at a predetermined height by the pedestal 4 and the chest mat 5 at the front of the bogie, and the arms are freely extended forward of the bogie 1. In this state, the grass can be efficiently and reliably extracted from the roots with both hands while holding the grass with one hand and using a weeding tool with one hand.

According to this weeding work cart, the lower body of the legs and waist is supported on the cart by placing the knee on the knee support mat 3 at the rear of the cart. The bending angle of the legs and waist placed on the knee rest mat 3 does not become as deep as weeding work that bends over the body, and the muscles of the legs are compressed by the weight of the upper body, The work can be performed without causing fatigue due to the weight of the upper body, and the forward movement can be easily performed by kicking the ground with feet.

The pedestal 4 at the front of the trolley and the breast mat 5 can stably support the upper body, which has been tilted forward to a prone position, at a predetermined height, so that both hands can be used freely. It is possible to support the upper body with the head somewhat higher and the waist lower, by making the breast support mat 5 an inclined surface with the rear edge lowered toward the rear of the bogie. It is possible to maintain a comfortable and stable posture suitable for weeding with both arms extended to the front of the trolley, instead of a posture where the head falls forward and the waist rises, The work can be continued for a long time in a state where the degree of fatigue is extremely low, which has the effect of improving this kind of work.
