Description

[Technical Field]

[0001] The present invention relates to a shoulder suspension support device for carrying luggage. [Background technology]

[0002] In many work sites, loads are transported manually, but this transport work places a heavy load on the hands and arms of the transporter, which can injure the hands and arms and can easily cause hand fatigue, making repeated transport more likely to result in injury due to accumulated fatigue. Therefore, assistive devices have been proposed in the past to prevent excessive loads on the hands and arms of transporters and reduce fatigue (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2006-288797 Summary of the Invention [Problem to be solved by the invention]

[0004] However, while conventional assistive devices can prevent excessive strain on the hands and arms and reduce fatigue, the load itself must be held by the transporter's hands, and there is a risk that repeated transports will cause hand fatigue and make it difficult to hold the load.

[0005] Therefore, the object of the present invention is to provide a shoulder suspension support device that can securely hold cargo (carried objects) such as formwork and plastic cases used in factories and agricultural work sites without straining the hands, arms, or shoulders of the transporter, and that can flexibly respond even if the cargo is tilted in its holding position during transport, allowing the transporter to continue carrying the cargo safely and reliably. [Means for solving the problem]

[0006] The shoulder suspension support device of the present invention comprises a belt portion that hangs down from the user's shoulder, a J-shaped curved hook plate piece that is indirectly or directly connected to the lower end of the belt portion, and a retaining plate having a horizontal upper surface that is freely swingably fitted onto a horizontal shaft portion formed on the lower tip edge of the hook plate piece. It also comprises a shoulder rest for wearing on the user's shoulders, a belt hanging from the shoulder rest, a belt loop for threading the belt, a connecting ring held rotatably around a vertical axis by the belt loop, a J-shaped curved hook plate held in a suspended state by the connecting ring, and a holding plate with a horizontal upper surface that is fitted so as to be able to swing freely onto a horizontal shaft with a circular bulge in cross section formed on the lower tip edge of the hook plate and that holds the transported object from below. In addition, the retaining plate has a dovetail groove that opens downward, and the horizontal shaft portion of the hook plate piece is pressed into the dovetail groove, so that the retaining plate is fitted to the horizontal shaft portion so that it can swing freely at a small angle. The holding plate has a rubber or plastic anti-slip piece fixed to the top surface. It is something. [Effects of the Invention]

[0007] According to the present invention, a heavy object can be held securely without hurting the hands, arms, and shoulders of a transport worker, and even if the holding posture of the object tilts during transport, the work of transporting the object can be flexibly dealt with, allowing the transporting work to be continued safely and securely. [Brief explanation of the drawings]

[0008] [Figure 1] 1 is a perspective view showing an embodiment of a shoulder hanging support device of the present invention. [Figure 2] FIG. [Figure 3] FIG. [Figure 4] FIG. [Figure 5] FIG. [Figure 6] FIG. DETAILED DESCRIPTION OF THE INVENTION

[0009] The present invention will be described in detail below based on the illustrated embodiments. 1 and 2, the shoulder suspension support device 1 of the present invention comprises a pair of shoulder rests 2, 2 to be worn on the shoulders of a user (carrier), a belt 4 fixed to and hanging down from the shoulder rest 2, a belt loop 5 through which the belt 4 passes, a connecting ring 6 attached to the belt loop 5 via a rotating portion 6a so as to be rotatable about a vertical axis L6, a hook plate 7 connected to the connecting ring 6 and attached so as to be swingable about a hole 7a, and a holding plate 8 fitted to the horizontal shaft 7b of the hook plate 7 so as to be swingable. The belts 4, 4 fixed to the pair of shoulder rests 2, 2 are connected by connecting straps 4a, 4a.

[0010] The shoulder rest 2 has a cushion 3 that comes into contact with the user's shoulder, and the belt 4 is passed through a belt loop 5 to suspend the connecting ring 6 and hook plate 7. The cushion 3 is preferably made of a material that is moderately soft and elastic (such as urethane rubber) so that the user does not feel any pressure or pain when wearing it. The length of the belt 4 is adjustable (not shown) so that the position of the hook plate 7 (the distance from the shoulder rest 2) can be adjusted according to the user's physique (arm length). The belt 4 is also preferably made of a material that is sufficiently strong and flexible (such as a synthetic fiber such as polyester).

[0011] As shown in Figures 2 and 3, the connecting ring 6 is attached to the belt loop 5 via the rotating portion 6a so as to be rotatable about the vertical axis L6 as indicated by arrow A. The hook plate 7 is attached to the hole 7a so as to be swingable back and forth as indicated by arrow B. The holding plate 8 is fitted to the horizontal shaft 7b of the hook plate 7 so as to be swingable as indicated by arrow C. This structure allows for flexible adjustments to the position of the bag during transport. The hook plate 7 may be attached to the connecting ring 6 in any manner as long as it is held swingably. The hook plate 7 is formed in a curved J-shape when viewed from the front to back. This shape allows the user's hand to fit easily on the curved surface of the hook plate 7 when carrying luggage (carried object), ensuring stable transport of the luggage.

[0012] The hook plate 7 has a horizontal shaft portion 7b, and the holding plate 8 is fitted onto the horizontal shaft portion 7b so as to be able to swing freely. In the illustrated embodiment, the horizontal shaft portion 7b is fitted into a dovetail groove 8b formed integrally with the holding plate 8, but the method of attaching the holding plate 8 to the hook plate 7 is free as long as the holding plate 8 is able to swing freely on the horizontal shaft portion 7b. The holding plate 8 is for placing and holding cargo (carried objects) such as formwork or plastic cases, and has anti-slip pieces 8a made of elastic plastic material such as rubber or urethane fixed to its upper surface. The surface of the anti-slip pieces 8a is preferably uneven or embossed.

[0013] As shown in Figures 2 and 3, the hook plate piece 7 swings around the hole 7a in the direction of arrow B in the forward and backward directions relative to the direction of travel of the user when using the shoulder hanging support device 1 to carry a load. The connecting ring portion 6 also rotates around the vertical axis L6 relative to the belt loop portion 5 as shown by arrow A. Furthermore, the holding plate 8 swings around the horizontal axis portion 7b as shown by arrow C. This configuration allows for flexible handling of the carrying position of the load 10 (exemplified as a formwork in Figures 4 and 5) placed on the holding plate 8.

[0014] For example, even when transporting on a slope or in a place that is tilted to the left or right when viewed from the direction of travel when transporting the formwork (carried object) 10, the formwork (carried object) 10 can be kept in a horizontal position. To flexibly accommodate various transport conditions, it is desirable that the connecting ring portion 6 can rotate 360° and that the hook plate piece 7 and the holding plate 8 can each swing at an angle of approximately plus or minus 45°.

[0015] 1 to 6, the hook plate 7 is connected to the lower end of the belt 4 via the belt loop 5, the connecting ring 6, etc. If this is referred to as an "indirect" connection between the lower end of the belt 4 and the hook plate 7, it is also possible to use other members (not shown) to "indirectly" connect them instead of the belt loop 5 and the connecting ring 6 shown in Figures 1 to 6, or to add a separate member (not shown) to "indirectly" connect them. Alternatively, it is also possible to "directly" connect the lower end of the belt 4 to the hook plate 7 without using the belt loop 5 or the connecting ring 6 (not shown).

[0016] Figure 4 shows the shoulder suspension support device 1 of the present invention in a worn state. After adjusting the belt 4 to an appropriate length, the arm is passed through the belt portion 4, the shoulder pad portion 2 is placed over the user's shoulder, and the cushion portion 3 is placed in close contact with the shoulder and chest. The device can be easily worn by simply passing the arm through the belt portion 4 and placing the shoulder pad portion 2 over the user's shoulder.

[0017] 4 and 5, the user holds the hook plate piece 7 with the palm and fingers, hooks the holding plate 8 onto the inside surface of the upper edge of the formwork 10, and lifts the formwork 10. The inside surface of the upper edge of the formwork 10 is stably held on the holding plate 8 without moving due to the anti-slip piece 8a on the upper surface of the holding plate 8.

[0018] During transportation, it is possible that the transporter may accidentally open his / her fingers. In this case, if the transporter carries the formwork 10 directly with his / her hands, the formwork 10 may fall, causing an accident.

[0019] However, when a user (carrier) is carrying formwork 10 using the shoulder suspension support device 1 of the present invention, even if the user unintentionally spreads their fingers, the inner surface of the upper edge of formwork 10 is held in place by the frictional force of the holding plate 8, and the weight of formwork 10 can be borne by shoulder rest 2 via belt 4, preventing formwork 10 from falling. Furthermore, when the load L of formwork 10 is applied to hook plate 7, the J-shape of the curved surface of hook plate 7 generates force F that presses the curved surface of hook plate 7 toward the user's hand, and this synergistic effect with the frictional force of holding plate 8 reliably prevents formwork 10 from falling.

[0020] In the above embodiment, the formwork 10 was described as the object to be transported, but the shoulder suspension support device 1 of the present invention can also be used in the same manner as described above when transporting other types of objects with flat bottoms, such as wooden boxes, plastic containers, metal containers, etc.

[0021] Figure 6 shows a plastic case with a horizontal band-like flange (outer flange) as the transported object 10. This plastic case is used in agricultural work to harvest fruit and the like, and the plastic case is transported by hooking a holding plate 8 onto the underside of the horizontal band-like flange formed on the top edge of the plastic case containing fruit and the like. As can be seen from Figure 6, the shoulder hanging support device 1 of the present invention is suitable for transporting plastic cases, containers, and the like with horizontal band-like flanges.

[0022] The present invention is open to design modifications. For example, in the above embodiment, the belt portions 4, 4 fixed to a pair of shoulder rest portions 2, 2 are connected by connecting straps 4a, 4a, but other configurations are also possible as long as the structure allows the user to easily wear the shoulder hanging support device 1. For example, the shoulder rest portion 2 may be an integrally molded structure (not shown) having two belt fastening portions at the front and rear. Furthermore, the shapes and structures of the belt loop portion 5, connecting ring portion 6, and hook plate piece 7 may also be freely modified as long as they do not affect the swing direction and swing angle of each component described in Figures 2 and 3.

[0023] As described above, the present invention includes a belt 4 that hangs from the user's shoulder, a J-shaped hook plate 7 that is indirectly or directly connected to the lower end of the belt 4, and a holding plate 8 with a horizontal upper surface 18 that is swingably fitted onto a horizontal shaft 7b formed at the lower end of the hook plate 7. This allows the transporter to securely hold the transported object 10 without straining the transporter's hands, arms, or shoulders. It can also flexibly accommodate any tilting of the transported object 10 during transport, allowing the transporter to continue transporting the transported object 10 safely and reliably. Furthermore, the transporter can hold the transported object 10 even if the transporter opens his or her hand and stretches his or her fingers, preventing accidents during transport. The device is also suitable for transporting formwork at construction sites and plastic cases or containers with horizontal flanges at agricultural work sites.

[0024] The bag also includes a shoulder rest 2 for attachment to a user's shoulder, a belt 4 hanging from the shoulder rest 2, a belt loop 5 for threading the belt 4, a connecting ring 6 rotatably held by the belt loop 5 around a vertical axis L6, a J-shaped hook plate 7 suspended by the connecting ring 6, and a holding plate 8 with a horizontal upper surface 18 that is swingably fitted onto a horizontal shaft 7b with a circular cross section formed at the lower end of the hook plate 7 and that holds the load 10 from below. This allows the load 10 to be securely held without straining the hands, arms, or shoulders of the transporter. It can also flexibly accommodate any tilting of the load 10 during transport, allowing the transporter to continue transporting the load safely and reliably. Furthermore, the load 10 can be held even when the transporter opens his or her hand and extends his or her fingers, preventing the load 10 from falling during transport. It is also suitable for transporting formwork at construction sites, plastic cases and containers with horizontal band flanges at agricultural work sites, etc.

[0025] Furthermore, the holding plate 8 has a downwardly opening dovetail groove 8b, and the horizontal shaft portion 7b of the hook plate piece 7 is pressed into the dovetail groove 8b, and the holding plate 8 is fitted to the horizontal shaft portion 7b so that it can swing freely at a small angle. Therefore, even if the holding posture of the transported object 10 is tilted, it can flexibly respond, and the transporting operation of the transported object 10 can be carried out safely and reliably.

[0026] In addition, the holding plate 8 has anti-slip pieces 8a made of rubber or plastic fixed to the upper surface, so that the transported object 10 can be securely held by frictional force, and accidents such as the transported object 10 slipping and falling during transport work can be prevented.
