Sandbag carrier tool

Abstract

To provide a carrier tool that enables a user to manually hold and carry bag-shaped load such as sandbags made of slippery material, sealed water bags, and fertilizer bags.SOLUTION: The sandbag carrier tool includes: a handle (1) made by bending a metal rod into a U-shape; a frame (2) made by bending a metal rod into an approximately rectangular shape; a lever (3) made by bending a metal rod into a U-shape; and a metal hinge (4). The hinge and the center of the lever grip and fix the top of a bag-shaped cargo. When a grip part of the handle is lifted, the top of the frame and the right and left parallel bars of the handle come into contact and form a mechanical fulcrum, forming a heaver, and a force multiplied by the ratio of the load generated in the grip part due to the action of the heaver with the ratio being a distance between the grip part of the handle, the formed fulcrum, and connecting parts (6a, 6b) is generated on the center of the lever and the hinge of a mounting frame, with connecting parts (5a, 5b) as an axis, so that a heavy bag-shaped object made of a slippery material is firmly held and can be carried stably.SELECTED DRAWING: Figure 1

Description

[Technical field]

[0001] The present invention relates to the manual transport of sandbags filled with rubble, soil, sludge, etc. (hereinafter collectively referred to as "soil") at civil engineering sites, construction sites, disaster sites, etc., and to the manual transport of heavy bag-shaped objects such as fertilizer and potting soil in agriculture, etc. [Background technology]

[0002] In various civil engineering works such as river improvement and bank construction, and in the event of a disaster or in a place where a disaster is expected, the work of packing excavated soil and sand into sandbags and transporting them is carried out everywhere. Several methods, such as simple jigs, have been proposed for packing excavated soil and mud into sandbags. As for transportation methods, wheelbarrows and dedicated transport vehicles have been proposed, but they are assumed to be used on leveled and flat ground, and are not satisfactory for wasteland, slopes, stairs, or unleveled ground, and the current situation is that the only way to transport them is by hand, one bag at a time. Therefore, patent applications for a sandbag transport device were filed in 2021 and 2022, but only sandbags with the top of the bag wrapped and fixed with a string or the like could be transported. Therefore, we will realize a transport device that can transport sealed bag-shaped heavy objects such as fertilizer bags and water bags. [Prior art documents] [Patent documents]

[0005] Summary of the Invention [Problem to be solved by the invention]

[0006] Sandbags weigh about 20 kg, so a large grip is required to grab the top of the bag with one hand and carry it, making it difficult for people with weak grip strength to even lift it. In addition, the weight of the sandbag is concentrated on the fingers of the handle, causing pain and making it difficult to work for long periods of time. Sandbag carrying devices were invented to make this work possible for people with weak grip strength and to make the transport of soil and sand more efficient, but conventional sandbag carrying devices hold the sandbags in place by utilizing the friction of the step created when the seam at the top of the bag is tied with string, so bags with the ends of the bag sealed by welding cannot be lifted and carried with conventional carrying devices. [Means for solving the problem]

[0007] A square frame (2) is made from metal rods, a hinge (4) is attached to one side of the frame, a U-shaped lever (3) is attached to the frame (2) with a screw or the like so that it rotates inside the frame (2) and interferes with the hinge (4), and a U-shaped handle (1) is connected to the end of the lever (3) with a screw or the like and installed through the inside of the frame (2). The inside of the movable part of the hinge (4) is treated to be non-slip, so that the ears of a bag-like item can be held by pinching the ears of the bag with the hinge (4) and then pressing the top of the bag with the lever (3). When the grip part of the handle (1) connected to the lever (3) is lifted, the handle (1) and frame (2) interfere with each other, and the lever (3) connected to the handle (1) is moved, which further presses the hinge (4), firmly holding the ears of the bag-like item. Furthermore, the part where the handle (1) interferes with the frame (2) serves as a fulcrum, and a lever action is exerted with the ratio of the distance from the fulcrum to the connection part of the lever (3) to the distance from the fulcrum to the grip part of the handle (1). As a result, a force times the ratio of the load applied to the handle (1) acts on the hinge (4) and lever (3), preventing the ears of the luggage gripped by the hinge (4) from coming off. Effect of the Invention

[0008] The sandbag carrying device of the present invention can hold and carry not only ordinary sandbags, but also water bags, fertilizer bags, rice bags, etc. that are made of slippery material and have no handles. [Brief description of the drawings]

[0009] [Figure 1] FIG. 2 is a front view showing the sandbag transporting device of the present invention. [Diagram 2] 1 is an explanatory diagram of assembling a sandbag to a sandbag transporting device. [Diagram 3] 1 is an explanatory diagram of assembling a water bag to a sandbag transporting device. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0010] Using the center of the metal rod as a reference, the left and right sides are bent parallel to each other at right angles, and then the left and right tips are bent inward at right angles to form a roughly rectangular shape. The left and right ends are connected and fixed to one of the wings of a hinge (4) parallel to the hinge's rotation axis by welding or screwing, etc. to form a frame (2). A metal rod is bent into a U-shape by its center and two parallel bars on the left and right sides of a lever (3) near the hinge (4) on the inside of the frame (2), and the center parts of the left and right parallel bars of the lever (3) are connected in an X-shape (5a, 5b) with screws or the like so that they can rotate inside the frame (2). The hinge (4) and the lever (3) are configured so that their centers overlap and interfere with each other. Furthermore, inside the ends of the left and right parallel bars of the lever (3), there are connecting parts (6a, 6b) connected with screws or the like so that the outside ends of the left and right parallel bars can be moved, with the central part of the handle (1) consisting of a metal bar bent into an approximately U-shape and the central part consisting of the two parallel bars serving as a grip part. The grip part of the handle (1) is located on the opposite side of the connecting parts (6a, 6b) through the inside of the frame (2). EXAMPLES

[0011] An embodiment of the present invention will be described with reference to the drawings. Figure 1 is a front view of the entire sandbag carrying device of the present invention, Figure 2 is an explanatory diagram of assembling a sandbag (7) to the sandbag carrying device, and Figure 3 is an explanatory diagram of assembling a water bag (8) to the sandbag carrying device. In Figure 1, the central part of a metal rod with an outer diameter of 5 to 15 mm is bent at a right angle to 80 to 150 mm, with the left and right sides being parallel to each other, with a width of 80 to 150 mm. Furthermore, the left and right tips are bent inward at a right angle of 20 to 50 mm to form an approximately rectangular shape. The left and right ends are attached to one of the wings of a metal hinge (4) with a thickness of 1 to 4 mm at an angle of 15 to 45 degrees to the structural plane of the frame (2) and parallel to the rotation axis of the hinge by screws, rivets or welding, thereby reinforcing the frame (2). A metal rod with an outer diameter of 5 to 15 mm is bent into a U-shape at its center and two parallel bars on the left and right to form a lever (3) near the hinge (4) on the inside of the frame (2). The center of the parallel bars is connected to the lever (3) in an X-shape (5a, 5b) with screws or the like so that it can rotate inside the frame (2), and the hinge (4) and the center of the lever (3) overlap and interfere with each other. Furthermore, a metal rod with an outer diameter of 5 to 15 mm is bent into an approximately U-shape on the inside of the tips of the parallel bars of the lever (3), and the center of the handle (1) is made up of a central part and two parallel bars, and the outside of the tips of the parallel bars are connected to the handle (1) with screws or the like so that they can move. The grip part of the handle (1) is located on the opposite side of the connecting parts (6a, 6b) through the inside of the frame (2).

[0012] To explain Fig. 2, first prepare a sandbag, pour in about 20 kg of sand, and then tie the opening of the bag with a string. Next, pass the top of the sandbag (7) through the frame (2) from the connecting parts (6a, 6b) side, fold the bag over, and pass it between the hinge (4) and the center part of the lever (3), and then pinch the top of the sandbag (7) between the hinge (4) and the center part of the lever (3). At this time, the movable part of the hinge (4) remains closed. When the handle (1) is lifted, the top of the bag is held down by the center of the hinge (4) and lever (3), creating a lever action with the grip of the handle (1) as the force point, the contact point between the frame (2) and the parallel bars of the handle (1) as the fulcrum, and the connecting parts (6a, 6b) as the point of application, generating a force in the connecting parts (6a, 6b) that is times the weight of the sandbag (7), which acts on the center of the hinge (4) and lever (3) via the connecting parts (5a, 5b), firmly holding the top of the sandbag (7). Furthermore, by lifting the handle (1), the sandbag (7) can be transported stably.

[0013] To explain Fig. 3, the movable piece of the hinge (4) is opened and the ears of a water bag (8) inflated with water or a sealed bag-like item are clamped by the hinge (4). The inside of the movable piece of the hinge (4) is treated to be non-slip, and after clamping the ears, the top of the bag is folded back and then the top of the bag is held down by the lever (3). When the handle (1) is lifted, the ears of the bag are held down by the center of the hinge (4) and lever (3). A lever action is exerted with the grip part of the handle (1) as the force point, the contact point between the frame (2) and the parallel bars of the handle (1) as the fulcrum, and the connecting parts (6a, 6b) as the point of action, and a force times the ratio of the weight of the water bag (8) is generated in the connecting parts (6a, 6b), which acts on the center of the hinge (4) and lever (3) via the connecting parts (5a, 5b), so that the ears of the water bag (8) can be held firmly. Furthermore, by lifting the handle (1), sealed bag-like cargo such as a water bag (8) can be transported stably. [Explanation of symbols]

Claims

1. The present invention is a transport device for manually transporting bag-shaped cargo consisting of bag-shaped containers filled with soil and sand, and is configured such that a metal rod is bent at right angles so that its left and right sides are parallel to each other, based on its center, and then the left and right tips are bent inward at right angles to form a roughly rectangular shape, and the left and right ends are connected and fixed to one of the wings of a hinge (4) parallel to the hinge's rotation axis by welding, screwing, etc. to form a frame (2), and a metal rod is bent at its center and two parallel bars on the left and right sides of a lever (3) on the inside of the frame (2) near the hinge (4), and the center parts of the left and right parallel bars of the lever (3) are connected in an X-shape with screws or the like so that they can rotate inside the frame (2), and the hinge (4) and the lever (3) are configured so that their centers overlap and interfere with each other. Furthermore, inside the tips of the left and right parallel bars of the lever (3), there are connecting parts (6a, 6b) connected with screws or the like so that the outsides of the tips of the left and right parallel bars can be moved, with the central part of the handle (1) consisting of a metal bar bent into a roughly U-shape and the central part consisting of the two parallel bars serving as a grip part. The grip part of the handle (1) is located on the opposite side of the connecting parts (6a, 6b) through the inside of the frame (2). When the top of a bag-shaped item such as a sandbag (7) is passed between the hinge (4) of the frame (2) and the center of the lever (3) and then the grip portion of the handle (1) is lifted, the left and right parallel bars of the handle (1) come into contact with the top of the frame (2), and when the connecting portions (6a, 6b) move in reaction to this, the lever (3) connected to the connecting portions (6a, 6b) rotates about the axis of the connecting portions (5a, 5b), and the hinge (4) and the center portion of the lever (3) grab and secure the top of the bag-shaped item, making it possible to lift and transport the bag-shaped item such as a sandbag (7).

2. A transport device as claimed in claim 1, characterized in that when the grip portion of the handle (1) is lifted, the left and right parallel bars of the handle (1) come into contact with the upper part of the frame (2) and form a mechanical fulcrum, thereby forming a lever, and has a force multiplying function with a ratio equal to the distance between the grip portion of the handle (1), the formed fulcrum, and the connecting portions (6a, 6b). Therefore, when the weight of a bag-like cargo is transmitted to the handle (1), the multiplying force generated in the connecting portions (6a, 6b) by the lever action is transmitted to the center of the lever (3) and the hinge (4), which is the holding portion of the mounting frame (2), with the connecting portions (5a, 5b) as the axis, thereby allowing the bag-like cargo sandwiched between them to be fixed and held more strongly than the ratio.

3. In claim 1, the inside of the hinge (4) is treated with an anti-slip coating, and the ear of a sealed bag-like luggage without a handle is clamped between the inside of the movable piece of the hinge (4), the top of the bag-like luggage is pressed down with the lever (3), and then the handle (1) is lifted, and the hinge (4) and lever (3) firmly press and hold the ear of the bag-like luggage due to the leverage action of claim 2, making it possible to lift and transport the sealed bag-like luggage without a handle.
