Description

  The present invention relates to an article lifting aid that can rotate an article such as a rice bag so that its posture is changed from vertical to horizontal and the lifting position is also set from the lower side to the upper side so that the article can be easily carried. .

Generally, in the case of rice bags as articles, a special bag is used, and rice is put in this bag and weighed with a measuring instrument. After that, it is held by hand and lowered from the measuring instrument, and the opening of the bag is closed. After that, it is transported by a forklift, loaded onto a truck or stored in a warehouse. In addition, it is also carried directly by hand without being placed on the pallet.
In this case, the rice bag has a longer vertical dimension than the horizontal dimension, and it is a heavy item that can hold up to about 30 kg when storing rice. If you hold such a heavy item by hand, Hateful. Therefore, although it is lifted in a state where it is laid down approximately 90 degrees, since the work of laying down and lifting is not easy, conventionally, auxiliary tools that can be easily laid down and carried have been developed.

  Conventionally, as this type of auxiliary tool, for example, one disclosed in Patent Document 1 (Japanese Patent Laid-Open No. 2009-161299) is known. As shown in FIG. 14, the auxiliary tool 100 is provided on the first placement portion 101 and the first placement portion 101 for placing an article W made of a rice bag that extends in a substantially horizontal direction. The second mounting portion 102 extending orthogonally, the rotation gripping portion 103 provided above the second mounting portion 102, and the first mounting portion 101 and the second mounting portion 102 are rotated by approximately 90 degrees. A main body 104 having an arcuate portion 104 a that can be made, a main body gripping portion 105 provided in the main body 104, and a wheel 106 provided in the main body 104 are provided.

  For example, when an article W made of a rice bag placed on the measuring instrument M and standing vertically is laid down, first, as shown in FIG. The main body 105 is moved to the vicinity of the weighing instrument M, and the article W on the weighing instrument M is placed on the first placement unit 101. Then, the main body gripping portion 105 is gripped with one hand, the rotary gripping portion 103 is gripped with the other hand, and the main body 104 is rotated. At this time, the main body 104 turns around the wheel 106 as a fulcrum, but is easily rotated by approximately 90 degrees by the arcuate portion 104a. In this state, the article W is supported on the second placement unit 102 and laid down. Since the article W made of a lying down rice bag is located near the waist of the user, it can be easily held with both hands and can be easily carried.

JP 2009-161299 A

By the way, in the above-mentioned conventional auxiliary tool 100, the main body 104 is turned around the wheel 106 as a fulcrum, and can be easily rotated by approximately 90 degrees by the arcuate portion 104a. If it is too sticky, there is a problem that it is inferior in safety because it rotates suddenly and the operator is swung around the assisting tool 100 or hits the assisting tool 100 or the article W falls. Further, in order to prevent such a sudden rotation, the grip portions 103 and 105 must be operated while being held down, so that there is a problem that the operability is inferior.
The present invention has been made in view of the above points, so that the posture can be changed from the vertical direction to the horizontal direction without suddenly rotating the article, and the lifting position can be positioned from the lower side to the upper side. An object of the present invention is to provide an article lifting aid that improves the operability and improves operability.

  In order to achieve such an object, the article lifting aid of the present invention comprises a base on which an article is placed on one end side, and a support having a support surface capable of supporting the article is provided on the base. The support body is tilted by an upright position where the support surface faces the side portion of the article placed on the base, and by pressing from the upright position to the other end of the base. A tilt position that is tilted by a predetermined angle, and a tilt position that is further tilted while being pushed upward by pressing toward the other end of the base from the tilt position to lie down on the article and support the article on the support surface. The base is provided with a support member for temporarily stopping the support at the inclined position and supporting the support from the inclined position to the recumbent position. Can move to 3 positions: position, tilt position and recumbent position The support has a configuration in which a coupling mechanism for coupling to the base to so that.

  Thus, for example, in the case where an article made of a rice bag, which is placed on a measuring instrument and is in an upright and standing state, is carried from the measuring instrument, first, the base is positioned near the measuring instrument, The article on the measuring instrument is transferred to the base. When the article is manually pressed against the support surface of the support body in the standing position and pressed, the support body tilts and is temporarily stopped at the inclined position by the support member. Further, when the article is pressed, the support body is supported by the support member and is further tilted while being lifted upward to be positioned in the recumbent position. In this state, the article lies on the support surface of the support and lies on its side. In this case, since the article is once positioned in the inclined position via the support and then reaches the recumbent position, that is, tilted in two stages, compared to the case where the article is laid down at a time as in the past, It is possible to prevent the situation where the worker is swung around the assisting tool, hits the assisting tool, or the article falls due to excessive momentum, and the safety can be improved. Moreover, since the support body is connected to the base by the connection mechanism, safety can be achieved also in this respect. Furthermore, since the article can be tilted simply by pressing it through the support, the operation is simple and the operability can be improved. In this recumbent position, the article is in a lying state and is located near the operator's waist, so that it can be easily held with both hands and can be easily carried.

And a second roller that supports the support and positions it in a recumbent position, and is provided with positioning means for positioning the support when the support reaches the recumbent position. As a result, when the article is manually pressed against the support surface of the support in the upright position, the support is tilted and is first brought into contact with the first roller to be positioned at the tilt position. Further, when this article is pressed, the support is lifted upward while being supported by the first roller, and is further tilted to abut against the second roller and is positioned in the recumbent position. In this case, since the first roller rolls on the bottom surface of the support body, the movement is smoothly performed accordingly, and the operability can be further improved. Also, the second roller rolls on the bottom surface of the support so that the movement can be facilitated. In addition, the height position of the first roller and the contact position with the bottom surface of the support body make it easy to temporarily stop the support body at the tilting position, and the support body is supported with the first roller as a fulcrum by subsequent pressing. It is good to set it so that it can move and move while tilting. When the support reaches the recumbent position, the support is positioned by the positioning means. Therefore, since the article does not wobble at the recumbent position, the article can be reliably carried.

In this case, if necessary, the positioning means is constituted by a concave portion provided on the bottom surface of the support body and engaged with the first roller and the second roller to restrict the movement thereof. The support can be reliably positioned at the recumbent position with a simple structure.
Further, it is effective to provide a plurality of the first rollers in the width direction of the base as required. Support is stable.
Furthermore, it is effective to provide a plurality of the second rollers in the width direction of the base as required. The support is further stabilized.

Furthermore, if necessary, the support surface of the support body is inclined to the other end side of the base at the standing position of the support body. The article can be easily leaned against the support surface of the support, and the article can be easily pressed.
Moreover, it is set as the structure which provided the protrusion which can latch the article | item on this support surface in the one side edge of the support surface of the said support body as needed. Since the article can be locked while the support is tilted, the article can be prevented from dropping from the support surface.

  Further, if necessary, the base includes a substrate on which the article is placed, a base member that supports the substrate, and a height adjustment mechanism that can adjust the height of the substrate relative to the base member. Is configured. Since the height of the substrate can be adjusted, the height at the recumbent position where the article is lifted can be adjusted, and the article can be easily carried in accordance with the operator and the article.

Furthermore, it is set as the structure which provided the accommodation space which can accommodate an accessory in the said base and / or a support body as needed. Convenient because it can accommodate small items
Moreover, it is set as the structure which provided the caster with the wheel which rolls the ground at the bottom part of the said base as needed. In a state where the article is supported on the base or in a state where the article is supported on the support, the base can be easily moved, and transport can be further facilitated.

  In addition, if necessary, the connection mechanism includes a fixed plate fixed to the base, a first movable plate having a one side edge portion rotatably provided on the fixed plate, and the first movable plate. And a second movable plate that is rotatably provided at the other side edge portion and is attached to the bottom surface of the support. Since the connection mechanism is a link mechanism, the operation can be surely performed, and the structure can be facilitated because the two butterfly plates (hinge mechanisms) are connected.

  According to the present invention, when the article is manually pressed against the support surface of the support body in the standing position and pressed, the support body tilts and is temporarily stopped at the tilt position by the support member. The support is supported by the support member and is further tilted while being raised upward, and is positioned in the recumbent position. However, since the article is once positioned in the inclined position via the support, it reaches the recumbent position. In other words, because it tilts in two stages, compared to the case where it lays down at a time as in the conventional case, the worker is too vigorous and the operator is swung around by the assisting tool, the assisting tool collides, or the article falls. Can be prevented and safety can be improved. Moreover, since the support body is connected to the base by the connection mechanism, safety can be ensured also in this respect. Furthermore, since the article can be tilted simply by pressing it through the support, the operation is simple and the operability can be improved.

Further, when the article W is pressed, the support 20 is lifted upward while being supported by the first roller 51, and further tilted by the lever principle with the first roller 51 as a fulcrum, as shown in FIG. 13 (c). As described above, the bottom surface 23 of the support 20 abuts against the second roller 52, and the support surface 21 is parallel to the top surface 3 of the base 1. In this case, since the first roller 51 rolls on the bottom surface 23 of the support 20, the movement can be performed smoothly and the operability can be improved. In addition, since the first roller 51 and the second roller 52 are provided in the width direction of the base 1, the support of the support body 20 is stabilized.

  When the article W is further pressed, the first roller 51 and the second roller 52 roll on the bottom surface 23 of the support 20, and the support 20 further moves to the other end side of the base 1. As shown in FIG. 13, the concave portion 55 as the positioning means is engaged with the first roller 51 and the second roller 52 and its movement is restricted and stopped, and as shown in FIG. Positioned at the recumbent position Z. In this case, since the first roller 51 and the second roller 52 roll on the bottom surface 23 of the support 20, the movement can be performed smoothly and the operability can be further improved. In this case, as shown in FIG. 12 (b), the article W is temporarily positioned at the tilt position Y, tilted at the angle θ (FIG. 7) and stopped, and then the recumbent position. Since it reaches Z, i.e., it tilts in two stages, compared with the case where it lays down at a time as in the prior art, it is too vigorous and the operator is swung around the auxiliary tool S or hits the auxiliary tool S. Or the situation where the articles | goods W fall is prevented and the improvement of safety | security can be aimed at. Moreover, since the support body 20 is connected with the base 1 by the connection mechanism 60, safety can be achieved also in this respect. Furthermore, since the article W can be tilted simply by pressing it through the support 20, the operation is simple and the operability can be improved.

  Then, in the state shown in FIG. 13 (d), the base 1 is caused to travel, for example, transported to the vicinity of the pallet, a truck, or a warehouse, and the article W is lowered from the support 20. In this case, at the recumbent position Z of the support 20, the article W is in a laid-down state and is located near the operator's waist, so that it can be easily held with both hands and can be easily carried. Further, in this case, since the first roller 51 and the second roller 52 are engaged with the concave portion 55 serving as positioning means and the support 20 is positioned, the article W is less likely to wobble at the recumbent position Z. It will be possible to carry it with certainty. Further, the height of the base 1 is adjusted by the height adjustment mechanism 6, and therefore the support surface 21 of the support 20 is set at an appropriate position, so that the article W can be easily carried by that much. .

  In the lifting assist tool S for the article W according to the above embodiment, the first roller 51 and the second roller 52 are provided in pairs, but the present invention is not necessarily limited to this, and the width in the axial direction is not necessarily limited thereto. If it is large, it may be one by one, or three or more may be provided, and may be changed as appropriate. Further, the support member 50 is constituted by the first roller 51 and the second roller 52, but is not necessarily limited thereto. The second roller 52 is simply replaced with a block-shaped member, or the first roller 51 and The second roller 52 may be appropriately changed, for example, by replacing it with a block-shaped member. Moreover, in the lifting aid S for the article W according to the above-described embodiment, the case where the rice bag is lifted as the article W has been described. However, the present invention is not necessarily limited thereto, and can be applied to any article W. Of course.
