Description

[Technical Field]

[0001] The present disclosure relates to an assistive tool and a lifting cart. [Background technology]

[0002] Conventionally, when refueling a vehicle (e.g., a test vehicle, forklift, etc.) at a location other than a gas station, a worker holds a portable fuel can in his / her hand, lifts it close to the vehicle's fuel filler neck, and adjusts the position of the hose end with one hand to prevent the fuel from spilling. However, because the portable can is heavy, it places a heavy burden on the worker.

[0003] In order to solve such problems, for example, Patent Document 1 discloses an invention in which a work machine to be refueled is provided with a mounting surface on which a portable can can be placed. [Prior art documents] [Patent documents]

DETAILED DESCRIPTION OF THE INVENTION

[0011] Hereinafter, embodiments of the present disclosure will be described with reference to the drawings. Note that common components in the drawings are denoted by the same reference numerals, and descriptions thereof will be omitted as appropriate.

[0012] First, the configuration of an assistive tool 1 of this embodiment will be described with reference to Fig. 1. In Fig. 1, the upper figure is a top view of the assistive tool 1, and the lower figure is a side view of the assistive tool 1.

[0013] 1 is a tool for assisting in work requiring lifting of a heavy object. In this embodiment, an example will be described in which the assisting tool 1 assists in refueling work using a portable can (an example of a heavy object).

[0014] As shown in FIG. 1, the assisting tool 1 has a holding part 2 that holds a portable can 20 (see FIGS. 3 to 5) described later, and a seat part 3 that is attached to a base part 13 (see FIGS. 2 to 3 and 5) of a lifting cart 10 described later.

[0015] The holder 2 has a bottom portion 2a and two side portions 2b. The bottom portion 2a and the two side portions 2b are each a rectangular flat plate member. The two side portions 2b are provided at both ends of the bottom portion 2a along the long side direction and perpendicular to the bottom portion 2a. The two side portions 2b face each other, separated by a distance in the short side direction of the bottom portion 2a. A portable can 20, which will be described later, is placed on the bottom portion 2a.

[0016] In this embodiment, the bottom surface 2a is a rectangular flat plate, but the present invention is not limited to this and may have any shape as long as it can stably support a heavy object. Furthermore, the weight may be reduced by forming a plurality of openings in the bottom surface 2a (for example, by forming the bottom surface 2a in a ladder shape).

[0017] The seat portion 3 is a rectangular frame-shaped member, and has a shape that allows it to be fitted in the height direction into the base portion 13. In this embodiment, the seat portion 3 is a frame-shaped member to reduce weight, but is not limited to this and may have another shape (for example, a box-shaped member in which only the lower of two opposing bottom surfaces is open).

[0018] The holding part 2 is rotatably supported along one side of the seat part 3. Specifically, the holding part 2 is rotatably supported by a rotation hinge 4 provided along the short side direction of the seat part 3. The rotation hinge 4 is formed, for example, by bolts, nuts, washers, etc., but may also be formed by other known parts.

[0019] The holding part 2 and the seat part 3 are connected via a damper 8. One end of the damper 8 is fixed to the side surface part 2b of the holding part 2, and the other end of the damper 8 is fixed to the seat part 3 (not shown). As the damper 8, a known one can be used.

[0020] The holding portion 2 is provided with a handle 5, a guard portion 6, and an opening 7.

[0021] The handle 5 is a rod-shaped member, one end of which is fixed to the side surface portion 2b. After fixing the portable can 20 to the holder 2, the worker performing the refueling operation grasps the handle 5 and rotates the one end of the holder 2.

[0022] The guard part 6 is a rectangular flat plate member that is provided along the short side direction of the bottom part 2a and perpendicular to the bottom part 2b. The guard part 6 functions as a stopper that prevents the portable can 20 from falling when the holding part 2 holding the portable can 20 tilts due to rotation.

[0023] The opening 7 is an elongated hole formed in the side surface portion 2b. A lashing belt 9 (see FIGS. 3 to 5), which will be described later, is passed through the opening 7.

[0024] The shapes and installation positions of the handle 5, guard portion 6, and opening 7 are not limited to those shown in FIG.

[0025] Next, the lifting cart 10 of this embodiment will be described with reference to Fig. 2. Fig. 2 is a side view of the lifting cart 10.

[0026] As shown in Figure 2, the lifting cart 10 has a handle 11 that is held by an operator, wheels 12 that are placed on the ground and rotate to move the lifting cart 10, a flat base 13 on which the cargo to be transported is placed, and a lifting unit (jack) 14 that is operated by an operator to raise and lower the base 13 in the direction of arrow A.

[0027] In the lifting cart 10, normally, a load to be transported is placed on the base 13, but in this embodiment, the assisting tool 1 is attached to the base 13. A specific example of this will be described later.

[0028] The above describes the lifting cart 10 of this embodiment, but the cart applicable to the present disclosure is not limited to the lifting cart as shown in Figure 2, and may be any cart having a base to which the auxiliary tool 1 can be attached.

[0029] Next, an example of the procedure for using the assistive tool 1 will be described with reference to Figures 3, 4, and 5. Figure 3 is a side view showing the assistive tool 1 attached to the lifting cart 10. Figure 4 is a top view showing the assistive tool 1 holding a portable can 20. Figure 5 is a side view showing the holding part 2 holding the portable can 20 in an inclined position.

[0030] First, the worker attaches the auxiliary tool 1 in the state shown in FIG. 1 (specifically, with the holding part 2 folded) to the base part 13 of the lifting cart 10 shown in FIG. 2. As described above, the seat part 3 has a shape that allows it to be fitted into the base part 13 in the height direction. Therefore, the worker fits the seat part 3 from its lower side into the upper side of the base part 13. In this way, the auxiliary tool 1 is attached to the base part 13 as shown in FIG. 3.

[0031] Next, the worker places the portable canister 20 containing the refueling fuel on the holder 2 (specifically, the bottom surface 2a shown in FIG. 1) as shown in Figures 3 and 4. At this time, it is preferable that the portable canister 20 be placed so that the end of the portable canister 20 abuts against the guard 6 as shown in Figures 3 and 4.

[0032] Next, as shown in Figures 3 and 4, the worker passes a strip-shaped lashing belt 9 (an example of a fixing member) through the opening 7 and over the top of the portable can 20, and presses down and fixes the portable can 20 from above.

[0033] The cap 21 shown in Figures 3 and 4 is a lid member that can open and close a pouring spout (also called a fuel filler spout), not shown, provided on the portable can 20. The size and shape of the portable can 20 are not limited to those shown in Figures 3 and 4. Furthermore, the heavy object held by the holder 2 is not limited to the portable can 20, but may be any object of a size and shape that can be secured with the lashing belt 9 and will not fall from the holder 2 when the holder 2 rotates.

[0034] Next, the worker grips at least one of the handles 5 and rotates the holding part 2 in the direction of the arrow B. This causes the holding part 2 to rotate around the rotation hinge 4 as an axis.

[0035] The operator stops the rotation operation when the holder 2 has reached the desired inclination. The state at this point is shown in Figure 5. In the state shown in Figure 5, the operator inserts the hose (also called a nozzle) 22 inserted into the spout of the portable can 20 into the fuel filler port of the object to be refueled (for example, a vehicle, machine, etc.) (not shown) and begins refueling the fuel in the portable can 20.

[0036] After the refueling operation is completed, the worker grasps the handle 5 and rotates the holding part 2 in the direction opposite to the direction of the arrow B. This returns the holding part 2 to the state shown in FIG.

[0037] As described above, the assistive device 1 of this embodiment has a holding part 2 that holds a heavy object (e.g., a portable can 20) and a seat part 3 that is attached to a base part 13, and is characterized in that the holding part 2 is supported rotatably along one side of the seat part 3.

[0038] Therefore, the assisting tool 1 of this embodiment can reduce the burden on the worker when lifting and tilting the portable can 20 by hand and maintaining the tilted state, thereby reducing the risk of fuel leakage during work and the risk of the worker developing back pain. Furthermore, the seat portion 3 is detachable from the base, so it can be used with a variety of carts. In other words, the assisting tool 1 of this embodiment can significantly reduce the burden on the worker and improve versatility.

[0039] Furthermore, in the assisting tool 1 of this embodiment, the portable can 20 is secured by the lashing belt 9, so the risk of the portable can 20 falling can also be reduced.

[0040] Furthermore, the assistive device 1 of this embodiment has the effect of reducing the weight both when the holding part 2 is rotated and when it is returned to its original position, because the damper 8 connects the holding part 2 and the seat part 3. It also prevents accidents such as the holding part 2 suddenly folding up when returning the holding part 2 to its original position, resulting in fingers being pinched between the holding part 2 and the seat part 3. Furthermore, the damper 8 fully extends when the angle between the holding part 2 and the seat part 3 is about 90 degrees, so it can prevent the holding part 2 from tilting any further.

[0041] The present disclosure is not limited to the above-described embodiments, and various modifications are possible without departing from the spirit of the present disclosure.

[0042] For example, the assistive tool 1 may further have a locking mechanism for more firmly fixing the seat portion 3 to the base portion 13. For example, an example of a locking mechanism is a mechanism in which, after fitting the seat portion 3 into the base portion 13, both outsides of the overlapping portion of the seat portion 3 and the base portion 13 are sandwiched between U-shaped members, and then a bolt is passed through all of them and tightened with a nut. By using such a locking mechanism, the assistive tool 1 can be firmly fixed to the base portion 13, improving work efficiency. [Industrial Applicability]

[0043] The assistive tool and lifting cart of the present disclosure are useful for assisting in tasks that require lifting heavy objects. [Explanation of symbols]
