As shown in FIGS. 1 to 3, the transportation support device 1 includes a band 3, a shoulder pad 4, a connecting portion 5, and support mechanisms 6L and 6R.

(Band 3)
As shown in FIGS. 1 and 2, the band 3 includes a pelvic pad 30, a main belt 31, a sub-belt 32, a locking part 33, a plurality of sub-belt loops 34, and a plurality of main belt loops 35. Equipped with

The pelvic pad 30 is a band-shaped cushioning material that is wrapped around the user's 2 pelvic region. This pelvic region is approximately the same as the user's 2 buttocks.

The main belt 31 is wound around the pelvis pad 30 and fastened to the pelvic region of the user 2 via the pelvis pad 30. The main belt 31 is passed through a plurality of main belt loops 35 provided on the pelvic pad 30, as shown in FIG. The width of the main belt 31 is narrower than the width of the pelvic pad 30. A fastener 31a for fastening the main belt 31 to the pelvic region of the user 2 is provided at one end in the longitudinal direction of the main belt 31. The user 2 attaches the pelvic pad 30 to his or her pelvic region by tightening the main belt 31 with the fastener 31a. The pelvic pad 30 applies the tightening force of the main belt 31 to the pelvic region of the user 2 in a distributed manner, so that the burden on the user 2 can be reduced.

The sub-belt 32 is fastened around the user's 2 waist. The sub-belt 32 is passed through a plurality of sub-belt loops 34 extending above the pelvic pad 30, as shown in FIG. Although the width of the sub-belt 32 is set narrower than the width of the main belt 31 in this embodiment, it is not limited to this and can be set arbitrarily. A fastener 32a for fastening the sub-belt 32 to the waist of the user 2 is provided at one end in the longitudinal direction of the sub-belt 32. The user 2 tightens and wears the sub-belt 32 around his or her waist using the fastener 32a.

The locking portion 33 is configured to lock the connecting portion 5, and is formed of, for example, a D-shaped pin. The locking portion 33 is passed through and supported by an upper support loop 36 provided at the upper end of the pelvic pad 30. The upper support loop 36 is provided, for example, at a portion of the pelvic pad 30 along the spine of the user 2 when the transportation support device 1 is attached to the user 2 (hereinafter referred to as the attached state).

A plurality of sub-belt loops 34 are provided at intervals in the longitudinal direction of the pelvis pad 30 when it is unfolded as shown in FIG. For example, the pelvis pad 30 is provided with four sub-belt loops 34.

A plurality of main belt loops 35 are provided at intervals in the longitudinal direction of the pelvis pad 30 when it is unfolded as shown in FIG. For example, the pelvic pad 30 is provided with five main belt loops 35. Among these, the above-described upper support loop 36 is provided above one main belt loop 35 that is provided at the center in the longitudinal direction of the pelvic pad 30 and located near the spine of the user 2 in the wearing state.

The remaining four main belt loops 35 are provided below the four sub-belt loops 34, corresponding to their respective positions. As described above, among the plurality of main belt loops 35, the one located below the sub belt loop 34 and at a position corresponding to the sub belt loop 34 is called a corresponding main belt loop. In this embodiment, a lower support loop 37 is provided below each of the four corresponding main belt loops. Although FIG. 2 shows the state in which the lower support loop 37 does not support anything, if necessary, a D-shaped spike or the like that is passed through and supported by the lower support loop 37 may be provided. good.

In this embodiment, a set of sub-belt loops 34, main belt loops 35, and lower support loops 37, which extend in the lateral direction of the pelvic pad 30 and are provided correspondingly, are integrally formed with a synthetic fiber band. It is formed. Specifically, by sewing this band to the pelvic pad 30, the set of sub-belt loops 34, main belt loops 35, and lower support loops 37 are configured to perform their respective functions. Further, one main belt loop 35 located near the spine of the user 2 in the worn state and a corresponding set of upper support loops 36 are integrally formed of a synthetic fiber band. Specifically, by suturing this band to the pelvic pad 30, one main belt loop 35 and a corresponding set of upper support loops 36 are configured to perform their respective functions. This makes it possible to reduce the number of parts and facilitate manufacturing.

(Differences from safety belts for electrical work)
Here, as a structure similar to but different from the band 3 of this embodiment, there is a safety belt used by electricians when working on poles, but it is clear that the structure and function of this safety belt and the band 3 are completely different. Keep it.

This safety belt includes a pad that is wrapped around the pelvic region of the pole worker and a safety belt that is wrapped around the pad. This safety belt is configured to be connectable to an auxiliary belt wrapped around the waist of the pole worker. This auxiliary belt always hangs the safety belt, and never the pad, in order to prevent pole workers from slipping through the safety belt and falling. In the band 3 of this embodiment, the main belt 31 is not suspended by the sub-belt loop 34 through which the sub-belt 32 is passed, but the pelvic pad 30 is suspended, so the structure and function are different from the safety belt used by electricians. is completely different.

Furthermore, an auxiliary strap for hanging the safety belt that secures the worker's posture when working on a pole and also functions as a seat needs to be used to hang the safety belt evenly in the front, back, left and right. On the other hand, in the band 3, the sub-belt 32 does not necessarily have to hang the pelvis pad 30 evenly on the front, back, right and left sides. The band 3 may have a configuration in which the sub-belt 32 suspends the pelvic pad 30 via the sub-belt loop 34 provided at an arbitrary position. There is also a big difference between the two in this respect.

(shoulder pad 4)
The shoulder pad 4 is a cushioning material that is placed on the shoulder of the user 2. Specifically, the shoulder pad 4 includes a backrest part 40 located on the back side of the user 2 (specifically, under the back of the neck) when worn, and an extension extending from the shoulder of the user 2 toward the front armpit. It includes existing parts 4L and 4R. As shown in FIG. 1, the extending portion 4L extends from the left shoulder of the user 2 toward the left front armpit, and the extending portion 4R extends from the right shoulder of the user 2 toward the right front armpit. The shoulder pad 4 is formed into, for example, a bow shape or an arc shape when it is unfolded as shown in FIG. 2 .

(Connection part 5)
The connecting portion 5 is configured to connect the band 3 and the shoulder pad 4, as shown in FIG. The connecting portion 5 is located on the back side of the user 2 in the wearing state. The connecting portion 5 includes a ring material 50, a first strap 51, and a second strap 52. Each of the first strap 51 and the second strap 52 has a band shape, for example.

The first strap 51 is configured to connect the ring material 50 and the locking portion 33 of the band 3. The first strap 51 is provided with an adjuster 51a for adjusting the length between the ring material 50 and the band 3.

The second strap 52 is configured to connect the ring material 50 and the shoulder pad 4. For example, the upper end of the second strap 52 is fixed to the back rest part 40.

(Support mechanism 6L, 6R)
The support mechanisms 6L and 6R are mechanisms that assist the user 2 in transporting the luggage W. The support mechanism 6L is provided to correspond to the left side of the user's 2 body, and the support mechanism 6R is provided to correspond to the right side of the user's 2 body. Since the support mechanism 6L and the support mechanism 6R have the same configuration, the support mechanism 6L will be mainly described below, and the description of the support mechanism 6R will be omitted as appropriate.

The support mechanism 6L includes a support belt 60, a first belt loop 61 and a second belt loop 62 through which the support belt 60 is passed, a slider 63, and a grip belt 64. In other words, the support mechanism 6R also has these configurations.

The support belt 60 is a continuous belt with one end fixed to the connecting portion 5. Specifically, as shown in FIG. 3, one end of the support belt 60 is fixed to the ring material 50. Here, the continuous belt is not necessarily limited to one belt, and may be any belt that is substantially continuous. For example, the support belt 60 may be a substantially continuous belt formed by joining a plurality of parts, as long as it does not interfere with the operation of the support mechanism 6L. The same applies to the support belt 60 of the support mechanism 6R.

Note that, in order to facilitate understanding of the characteristics of the support mechanism 6L, FIG. 3 is a diagram schematically showing a part of the transportation support tool 1 including the support mechanism 6L. It is preferable that each support belt 60 of the support mechanisms 6L, 6R is provided with an adjuster (not shown) that can adjust its length. The adjuster can be provided at any location as long as it does not interfere with the movement of the slider 63 relative to the support belt 60.

A foot loop 60a into which the foot of the user 2 is inserted is provided at the other end of the support belt 60. As shown in FIG. 1, the left foot is inserted into the foot loop 60a of the support mechanism 6L, and the right foot is inserted into the foot loop 60a of the support mechanism 6R. Specifically, the foot loop 60a is attached to the foot of the user 2 so as to surround the instep and arch of the foot of the user 3. Note that the foot loop 60a is preferably provided with an adjuster (not shown) that can adjust its diameter.

The first belt loop 61 of the support mechanism 6L is suspended from the extending portion 4L of the shoulder pad 4 via a hanging member 7. The hanging material 7 is composed of, for example, a band. In this way, the first belt loop 61 of the support mechanism 6L is connected to the extension portion 4L via the hanging member 7. Similarly, the first belt loop 61 of the support mechanism 6R is connected to the extension portion 4R via the hanging member 7. That is, the transportation support tool 1 includes a pair of extension parts 4L and 4R corresponding to the right and left halves of the user's 2 body, and a pair of support mechanisms 6L and 6R.

The first belt loop 61 has a shaft 61a extending in the width direction of the support belt 60, as shown in FIG. This shaft 61a rotatably supports the roller 61b. In this way, the first belt loop 61 is provided with a roller 61b on which the support belt 60 is placed.

The second belt loop 62 has a shaft 62a extending in the width direction of the support belt 60, as shown in FIG. In this embodiment, the support belt 60 is placed around this shaft 62a. Note that a configuration may be adopted in which a roller (not shown) is also provided in the second belt loop 62 so that the support belt 60 is not directly applied to the shaft 62a. In this configuration, for example, a roller on which the support belt 60 is applied may be rotatably supported by the shaft 62a.

The second belt loop 62 is connected to the band 3. For example, the second belt loop 62 of the support mechanism 6L is suspended between the leftmost sub-belt loop 34 in FIG. 2 of the band 3 and the corresponding main belt loop 35. For example, the second belt loop 62 of the support mechanism 6R is suspended between the sub-belt loop 34 located on the rightmost side in FIG. 2 of the band 3 and the corresponding main belt loop 35. .

Note that the connection position of the second belt loop 62 in the band 3 can be changed arbitrarily. For example, the second belt loop 62 may be suspended from the lower support loop 37. For example, the second belt loop 62 of the support mechanism 6L may be located near the upper part of the user's 2 left femur. Similarly, the second belt loop 62 of the support mechanism 6R only needs to be located above the right femur of the user 2.

The slider 63 is configured to be slidable with respect to the support belt 60. As shown in FIG. 4, the slider 63 includes a rectangular bezel 630, and a first insertion portion 631 and a second insertion portion 632 through which the support belt 60 is passed.

As shown in FIG. 3, the support belt 60 of this embodiment has a first insertion portion 631, a first insertion portion 631, a first The belt is passed through the belt loop 61, the second insertion portion 632, and the second belt loop 62 in this order. The support belt 60 of the support mechanism 6L passes under the left armpit of the user 2 from the end on the connecting portion 5 side to the first belt loop 61. That is, the left arm of the user 2 is passed between the portion and the shoulder pad 4. Similarly, the support belt 60 of the support mechanism 6R passes under the right armpit of the user 2 from the end on the connecting portion 5 side to the first belt loop 61. That is, the right arm of the user 2 is passed between the portion and the shoulder pad 4.

Specifically, the slider 63 has first to third shafts 63a to 63c that are parallel to each other and a holding portion 63d that holds the grip belt 64, as shown in FIG.

The first to third shafts 63a to 63c extend in the width direction of the support belt 60. The first shaft 63a constitutes a part of the bezel 630. The second shaft 63b is provided across the opening of the bezel 630. The third shaft 63c is located between the first shaft 63a and the second shaft 63b. The holding portion 63d is provided at the end of the bezel 630 opposite to the first shaft 63a. Note that the holding portion 63d may hold the grip belt 64 in any manner as long as it holds the grip belt 64 by a known method such as hooking, adhesion, or welding. For example, the holding part 63d may hold the grip belt 64 by hooking, and the grip belt 64 may be detachable from the holding part 63d.

The first insertion portion 631 described above is an opening portion formed between the first shaft 63a and the third shaft 63c. Further, the second insertion portion 632 described above is an opening portion formed between the third shaft 63c and the holding portion 63d. That is, the second insertion part 632 is provided at a position closer to the grip belt 64 than the first insertion part 631.

The slider 63 is provided with a first auxiliary roller R1 and a second auxiliary roller R2 that assist the sliding of the slider 63 with respect to the support belt 60.

The first auxiliary roller R1 is rotatably supported by the first shaft 63a. As shown in FIG. 3, a portion of the support belt 60 that passes through the first insertion portion 631 is applied to the first auxiliary roller R1. More specifically, this portion is a portion between the connecting portion 5 and the first belt loop 61 in the support belt 60.

The second auxiliary roller R2 is rotatably supported by the second shaft 63b. As shown in FIG. 3, a portion of the support belt 60 that passes through the second insertion portion 632 is applied to the second auxiliary roller R2. More specifically, this portion is a portion between the first belt loop 61 and the second belt loop 62 in the support belt 60.

The grip belt 64 is connected to the slider 63 and is a part that the user 2 holds in his hand (specifically, in his palm). As shown in FIG. 1, the grip belt 64 of the support mechanism 6L is held in the left hand of the user 2, and the grip belt 64 of the support mechanism 6R is held in the right hand of the user 2.

When the user 2 holds the luggage W, the user 2 holds the grip belt 64 together with the luggage W while applying the grip belt 64 to the luggage W. At this time, the grip belt 64 is caught between the user's 2 hand and the luggage W.

In order to make it easier to hold the luggage W and the grip belt 64, the grip belt 64 has a non-slip processed portion 64a, as shown in FIG. 1. The shaded area in FIG. 1 is an example of the formation range of the anti-slip processed portion 64a. Note that it is preferable that the anti-slip portions 64a be formed on both sides of the grip belt 64. The anti-slip portion 64a is made of a known anti-slip material such as silicone or other rubber, elastomer, or other elastic resin. The anti-slip portion 64a may be made of an anti-slip material that is directly formed on the grip belt 64 by coating or the like, or may be made of a sheet-like anti-slip material that is fixed to the grip belt 64 by pasting, sewing, etc. It's okay.

The configuration of the transportation support tool 1 has been described above. Next, the operation of the transportation support tool 1 will be explained mainly with reference to FIG. 3.

A portion of the support belt 60 between the slider 63 and the first insertion portion 61 becomes a wrap portion A that is folded back at the first insertion portion 61. The length of the wrap portion A changes depending on the position of the slider 63 that slides with respect to the support belt 60 depending on the posture of the user 2. The longer the length of the wrap portion A is, the shorter the effective length of the support belt 60 is, and the shorter the length of the wrap portion A is, the longer the effective length of the support belt 60 is. Become. By operating the slider 63 in this manner, even when the user 2 assumes various postures, the support belt 60 changes according to the posture, and the user's 2 movement is not obstructed by the support belt 60. is suppressed.

When the user 2 wearing the transportation support device 1 holds the cargo W placed at a reference position such as the ground, the user 2 bends forward (flexes the knees, spine, etc.) and holds the grip belt 64 with the hand. extend it to the baggage W, and grab the grip belt 64 along with the baggage W. When lifting the luggage W, the user 2 lifts the grip belt 64 together with the luggage W while gradually stretching the knees, spine, etc. On the other hand, when lowering the luggage W that has been lifted to a predetermined height, the user 2 performs the opposite operation to the above. During these operations, the slider 63 slides with respect to the support belt 60 in response to the user 2 holding the grip belt 64 together with the luggage W. That is, the slider 63 follows the change in the posture of the user 2 when the user 2 raises and lowers the luggage W, and the support belt 60 moves from one end (the end on the side of the connecting part 5) to the other end (on the side of the foot loop 60a). Creates a tensioned state with almost no slack, all the way to the ends.

Since the support belt 60 is continuous from one end to the other, the tension acting on each part of the support belt 60 can be considered to be approximately constant. Then, when the user 2 holds the grip belt 64 together with the luggage W, the force acting on the support belt 60 via the grip belt 64 and the slider 63 is applied to the connecting portion 5, the first belt loop 61, the second belt loop 62, and the foot. distributed in each of the loops 60a. That is, the force acting on the support belt 60 is distributed and transmitted to each of the user's 2 shoulders, pelvis, and feet.

When the user 2 lifts and lowers the load W without wearing the transportation support device 1, the heavier the load W is, the more the load is concentrated mainly on the arms and waist. In this case, if the user 2 repeatedly lifts and lowers the luggage W, there is a risk that the health of the user 2 may be harmed. On the other hand, according to the transportation support device 1, as described above, the force transmitted to the user 2 when lifting and lowering the luggage W can be dispersed to various parts of the user's body, thereby reducing the burden on the user 2 when holding the luggage W. It can be reduced. Therefore, health damage to the user 2 can be suppressed.

Further, in the band 3, the pelvis pad 30 is suspended from a sub-belt 32 that is fastened to the waist of the user 2 through a plurality of sub-belt loops 34. This structure of the band 3 allows the force acting on the pelvic pad 30 via the support belt 60 and the second belt loop 62 to be dispersed not only to the pelvic region but also to the lumbar region. Therefore, the burden on the user 2 when carrying the luggage W can be better reduced.

Here, FIG. 5 is a reference diagram showing the support mechanism 6L as a simplified pulley device. The same applies to the support mechanism 6R, but here, the support mechanism 6L will be described as a representative.

The string 9 corresponds to the support belt 60, the element E1 corresponds to the connecting part 5, the element E2 corresponds to the first belt loop 61, the element E3 corresponds to the second belt loop, and the element E4 corresponds to the foot loop 60a. This corresponds to the foot of user 2 that was passed through the foot. In FIG. 5, the positions of the elements E1 to E4 are deformed for simplicity. For further simplification, if the elements E2 and E3 are regarded as fixed elements, the slider 53 can be regarded as movable pulleys Q1 and Q2 connected to each other. In this case, the fixed pulley P1 fixed to the element E2 corresponds to the first belt loop 61, and the fixed pulley P2 fixed to the element E3 corresponds to the second belt loop 61. If the load acting on movable pulleys Q1 and Q2 connected to each other is M, and friction and resistance are ignored, then in the pulley device of FIG. 5, the force acting on element E1 and element E4 via string 9 is 1/4M. Become. That is, in this pulley device, the movable pulleys Q1 and Q2 connected to each other can be raised and lowered by relatively raising and lowering the element E1 and the element E4 with a force of 1/4M. If this is applied to the support mechanism 6L, it will be understood that the load applied to the slider 63 can be distributed to the support belt 60 with a smaller force than the load due to the function of the slider 63, which corresponds to the movable pulleys Q1 and Q2 that are connected to each other. will be done.

However, in reality, each of the elements E1 to E4 is displaced depending on the posture of the user 2, and friction, resistance, etc. act at various locations. It should be noted that FIG. 5 is merely a reference diagram to facilitate understanding of the function of the slider 63, and does not limit the effects of the present invention.

(Modified example)
From here on, a modification of the transportation support tool 1 will be explained. In the following, the same reference numerals as in the above embodiment will be used for components having the same functions as in the above embodiment, and the description thereof will be omitted as appropriate. In the following modified examples, differences from the above embodiment will be mainly explained.

The transportation support device 1 according to the modified example includes a band 3, a shoulder pad 4, a connecting portion 5, and support mechanisms 6L and 6R, similarly to the above embodiment. This modification differs from the above embodiment in how the slider 63 and support belt 60 are attached.

As shown in FIG. 6, the slider 63 according to the modification is a member in which the configuration corresponding to the second insertion portion 632 of the above embodiment is omitted. As shown in FIG. 7, the slider 63 has a rectangular bezel 630 and a first insertion portion 631 through which the support belt 60 is passed.

As shown in FIG. 6, the support belt 60 of the modified example has a first insertion portion 631, a first belt The belt is passed through the loop 61 and the second belt loop 62 in this order.

In the support belt 60, a portion from one end toward the first insertion portion 631 and a portion from the first belt loop 61 toward the second insertion portion 632 intersect. The portion where the support belts 60 intersect in this way is shown as an intersection C in FIG. In the support belt 60 of the support mechanism 6L according to the modification, the intersection C passes under the left armpit of the user 2. That is, the left arm of the user 2 is passed between the intersection C and the shoulder pad 4. The support belt 60 of the support mechanism 6R according to the modification is the same except that the left-right relationship is reversed from that of the support mechanism 6L.

Specifically, the slider 63 according to the modified example includes a first shaft 63a that constitutes a part of the bezel 630, and a holding portion 63d that holds the grip belt 64, as shown in FIG. The first insertion portion 631 according to the modification is an opening portion of the bezel 630.

The slider 63 is provided with a first auxiliary roller R1 that assists the sliding of the slider 63 with respect to the support belt 60. The first auxiliary roller R1 is rotatably supported by the first shaft 63a. As shown in FIG. 6, a portion of the support belt 60 that passes through the first insertion portion 631 is applied to the first auxiliary roller R1. More specifically, this portion is a portion between the connecting portion 5 and the first belt loop 61 in the support belt 60.

The operation of the transportation support tool 1 according to the modified example will be explained mainly with reference to FIG. 6.

In the support belt 60, the portion from the slider 63 to the intersection C becomes a wrap portion B that is folded back at the first insertion portion 61. The length of the wrap portion B changes depending on the position of the slider 63 that slides with respect to the support belt 60 depending on the posture of the user 2. The relationship between the effective lengths of the wrap portion B and the support belt 60 is the same as that described using the wrap portion A.

Also in the modified example, the slider 63 follows the change in the posture of the user 2 when the user 2 raises and lowers the luggage W, and the support belt 60 moves from one end (the end on the side of the connecting part 5) to the other end (the foot loop 60a). Creates a tensioned state with almost no slack until the end of the side.

Since the support belt 60 is continuous from one end to the other, the tension acting on each part of the support belt 60 can be considered to be approximately constant. Then, when the user 2 holds the grip belt 64 together with the luggage W, the force acting on the support belt 60 via the grip belt 64 and the slider 63 is applied to the connecting portion 5, the first belt loop 61, the second belt loop 62, and the foot. distributed in each of the loops 60a. That is, the force acting on the support belt 60 is distributed and transmitted to each of the user's 2 shoulders, pelvis, and feet. Therefore, the carrying support device 1 according to the modified example can also disperse the force transmitted to the user 2 when lifting and lowering the luggage W to various parts of the body, thereby reducing the burden on the user 2 when holding the luggage W. be able to.

Although not shown, if this modification is considered as a simplified pulley device as shown in FIG. 6, the slider 63 according to the modification can be regarded as one movable pulley. With half the force of the load acting on this movable pulley, one end and the other end of the string hung on the movable pulley can be relatively raised and lowered. In other words, although the transportation support device 1 according to the modified example is assumed to have less burden-reducing effect than the above-described embodiment, it is superior in that its configuration is simple. It should be noted that the pulley device considered here is also for reference only and does not limit the effects of the present invention.

The present invention is not limited to the above embodiments, modifications, and drawings. It is possible to make changes (including deletion of constituent elements) as appropriate without changing the gist of the present invention.

The shapes of the parts constituting the transportation support device 1 can be arbitrarily changed as long as their functions are not hindered, and suitable materials can be selected from a variety of materials.

For example, the structures referred to above as belts, straps, and hanging materials are not necessarily limited to band-like structures, and can be appropriately changed to strings, chains, ropes, wires, and the like.

Further, roller bearings may be employed as the roller 61b of the first belt loop 61, the roller (not shown) that can be provided on the second belt loop 62, and the first auxiliary roller R1 and second auxiliary roller R2 of the slider 53. good. Furthermore, a configuration may be adopted in which at least some of the rollers are omitted and the support belt 60 is applied to the target area without using the rollers.

The band 3 may be configured to be wrapped around at least one of the pelvic region and the waist region of the user 2. For example, it is also possible to omit the sub-belt 32 and the sub-belt loop 34 from the band 3.

Although the example in which one end of the support belt 60 is fixed to the ring material 50 has been described above, one end of the support belt 60 may be fixed to an arbitrary location in the connecting portion 5. Furthermore, one end of the support belt 60 may be fixed to the back rest part 40 of the shoulder pad 4 instead of the connecting part 5.

Here, the effects of the transportation support tool 1 according to the above embodiment and modification will be summarized.
