However, the working machine support belt of Patent Document 1 has room for improvement in reducing the load on an operator by distributing the load on the working machine to the upper body of the user.
The present invention provides a working machine support belt that can reduce a load on an operator.
According to the present invention, there is provided a working machine support belt including: a back plate portion; a left shoulder belt and a right shoulder belt that extend upward from an upper portion of the back plate portion and turn forward; a waist belt that extends from a lower portion of the back plate portion to both sides; a left suspender band that connects a front lower portion of the left shoulder belt and a left rear portion of the waist belt; a right suspender band that connects a front lower portion of the right shoulder belt and the right rear portion of the waist belt; a left side belt that extends left-downward from the upper portion of the back plate portion, turns forward, and is connected to a left end portion of the waist belt; a right side belt that extends right-downward from the upper portion of the back plate portion, turns forward, and is connected to a right end portion of the waist belt; a locking member that locks the left end portion of the waist belt and the left side belt which are connected to each other, and the right end portion of the waist belt and the right side belt which are connected to each other; and a pad member supported by the right rear portion of the waist belt via a rear support band, supported by the right end portion of the waist belt and the right side belt which are connected to each other via a front support band, and provided with a support member that supports a working machine.
According to the working machine support belt of the present invention, the load on the working machine can be more effectively distributed to the upper body compared to the related art. In addition, since the load on the working machine can be distributed around the entire waist of the operator, the deviation of the load that acts on a waist can be reduced, and fatigue due to a local load on the body of the operator can be reduced.
Hereinafter, an embodiment of the present invention will be described with reference to the attached drawings.
[Entire Configuration of Working Machine Support Belt]
As illustrated in
According to the above-described configuration, a load on the working machine can be distributed to an upper body of an operator P by the back plate portion 2, the left shoulder belt 3 and the left suspender band 6, the right shoulder belt 4 and the right suspender band 7, the left side belt 8, the right side belt 9, and the waist belt 5. Further, in the working machine support belt 1, by providing the left side belt 8 and the right side belt 9 and by locking the left end portion 5L of the waist belt 5 and the left side belt 8 which are connected to each other and the right end portion 5R of the waist belt 5 and the right side belt 9 which are connected to each other by the locking member 10, the load on the working machine can be distributed to the entire waist of the operator P, and thus, the deviation of the load that acts on the waist is reduced, and fatigue due to a local load on the body of the operator can be reduced. Further, since the back plate portion 2, the left shoulder belt 3, the right shoulder belt 4, the waist belt 5, the left side belt 8, and the right side belt 9 are made of cushion materials, the load on the operator P can further be provided.
The left shoulder belt 3 and the right shoulder belt 4 are formed integrally with the back plate portion 2 and configure a substantially Y-shaped belt main body 20. A lower end portion 20b of the belt main body 20 is connected to a center portion 5c of the waist belt 5. The back plate portion 2 and the waist belt 5 include reinforcing members 2a and 5d made of a hard resin member inside. According to the configuration, appropriate elasticity and rigidity can be imparted to the back plate portion 2 and the waist belt 5. Further, by using a hard resin member as the reinforcing member, it is possible to manufacture the working machine support belt 1 with a lighter weight and at a lower cost compared to a case where a metal is used for the reinforcing member.
The locking member 10 of the waist belt 5 is a side release type one-touch buckle, and includes a female member 11 as a left locking portion and a male member 12 as a right locking portion. In other words, the locking member 10 is configured such that a pair of locking pieces of the male member 12 is locked to a pair of locking recessed portions of the female member 11 by inserting the male member 12 into the female member 11, and the pair of locking pieces is disengaged from the pair of locking recessed portions by pushing the pair of locking pieces with a finger.
In addition, the working machine support belt 1 includes a reinforcing band 23 that connects the back plate portion 2 and the right rear portion 5b of the waist belt 5. The reinforcing band 23 is connected to the back plate portion 2 between a connection portion between the back plate portion 2 and the right side belt 9, and a connection portion between the back plate portion 2 and the waist belt portion 5, and the reinforcing pad 23 and the rear support band 13 are disposed substantially linearly. In this manner, since the reinforcing band 23 that connects the back plate portion 2 and the right rear portion 5b of the waist belt 5 is disposed substantially linearly with respect to the rear support band 13, the load on the working machine applied to the rear support band 13 can be appropriately received by the reinforcing band 23.
The left end portion 5L of the waist belt 5 and the left side belt 8 are connected to each other via a left connecting band 17. The right end portion 5R of the waist belt 5 and the right side belt 9 are connected to each other via a right connecting band 18. The left connecting band 17 is provided with the female member 11 of the locking member 10, and the front support band 14 is connected to the right connecting band 18 via a first length adjusting mechanism 19. The male member 12 of the locking member 10 is connected to the front support band 14 via a second length adjusting mechanism 21.
In addition, the right rear portion 5b of the waist belt 5 is provided with a third length adjusting mechanism 25, and the rear support band 13 is connected to the third length adjusting mechanism 25. The first length adjusting mechanism 19, the second length adjusting mechanism 21, and the third length adjusting mechanism 25 are ladder locks, for example. In this manner, since the front support band 14 is connected to the right connecting band 18 via the first length adjusting mechanism 19, by adjusting the length of the front support band 14, the length around the waist in the working machine support belt 1 can be adjusted.
Further, by changing a distance between the second length adjusting mechanism 21 and the pad member 16 in the front support band 14 and a distance between the third length adjusting mechanism 25 and the pad member 16 in the rear support band 13, the position of the hook 15 can be adjusted freely. In other words, by elongating both the distance between the second length adjusting mechanism 21 and the pad member 16 in the front support band 14 and the distance between the third length adjusting mechanism 25 and the pad member 16 in the rear support band 13, the position of the hook 15 can be lowered, and by shortening both the distance between the second length adjusting mechanism 21 and the pad member 16 in the front support band 14 and the distance between the third length adjusting mechanism 25 and the pad member 16 in the rear support band 13, the position of the hook 15 can be raised. Furthermore, by shortening the distance between the second length adjusting mechanism 21 and the pad member 16 in the front support band 14 and by elongating the distance between the third length adjusting mechanism 25 and the pad member 16 in the rear support band 13, the hook 15 can be moved forward, and by elongating the distance between the second length adjusting mechanism 21 and the pad member 16 in the front support band 14 and by shortening the distance between the third length adjusting mechanism 25 and the pad member 16 in the rear support band 13, the hook 15 can be moved rearward. In addition, manufacturing cost can be reduced by making the first length adjusting mechanism 19, the second length adjusting mechanism 21, and the third length adjusting mechanism 25 into a highly versatile ladder lock.
Length adjusting mechanisms 26 and 27 are provided in the front lower portions 3a and 4a of the left shoulder belt 3 and the right shoulder belt 4, respectively. The left suspender band 6 is connected to the front lower portion 3a of the left shoulder belt 3 via the length adjusting mechanism 26, and the right suspender band 7 is connected to the front lower portion 4a of the right shoulder belt 4 via the length adjusting mechanism 27. According to the configuration, by adjusting the length of the left suspender band 6 using the length adjusting mechanism 26 of the left shoulder belt 3, and by adjusting the length of the right suspender band 7 using the length adjusting mechanism 27 of the right shoulder belt 4, the position of the waist belt 5 can be adjusted in accordance with the operator P. In addition, the length adjusting mechanisms 26 and 27 are ladder locks, for example.
In the left suspender band 6, a base end portion 6a is stitched to the left rear portion 5a of the waist belt 5, and a tip end portion 6b side extends from the front lower portion 3a of the left shoulder belt 3 via the length adjusting mechanism 26. In the right suspender band 7, a base end portion 7a is stitched to the right rear portion 5b of the waist belt 5, and a tip end portion 7b side extends from the front lower portion 4a of the right shoulder belt 4 via the length adjusting mechanism 27. The right suspender band 7, the rear support band 13, and the reinforcing band 23 are gathered and stitched to the right rear portion 5b of the waist belt 5 to make the stitching work and the like easy.
A left through hole 8a into which the left suspender band 6 is inserted is provided in the left side belt 8, and a right through hole 9a into which the right suspender band 7 is inserted is provided in the right side belt 9. The left through hole 8a is formed by stitching both end portions of the band member 24 to the left side belt 8. The right through hole 9a is formed by stitching one end portion 18a and a middle portion 18c of the right connecting band 18 to the right side belt 9. In this manner, by making the left suspender band 6 inserted into the left through hole 8a provided in the left side belt 8, and by making the right suspender band 7 inserted into the right through hole 9a provided in the right side belt 9, the left suspender band 6 and the right suspender band 7 can be guided to a desired position, and thus, the integrity of the working machine support belt 1 can be improved, and the load on the working machine can be appropriately distributed to the upper body of the operator P. In addition, since the right through hole 9a of the right side belt 9 into which the right suspender band 7 is inserted is configured with a part of the right connecting band 18, the number of components can be reduced. in the front support band 14, a base end portion 14a is stitched and connected to the pad member 16, and a tip end portion 14b side extends via the second length adjusting mechanism 21 and the first length adjusting mechanism 19. A clip 22 is provided in the tip end portion 14b of the front support band 14 that serves as a free end. In this manner, since the clip 22 is provided in the tip end portion 14b of the front support band 14, flapping of the front support band 14 can be prevented by sandwiching the clip 22 by the right side belt 9 and the like.
Clips 28 are provided in the tip end portions 6b and 7b of the left suspender band 6 and the right suspender band 7, respectively. According to the configuration, flapping of the left suspender band 6 and the right suspender band 7 can be prevented by sandwiching each clip 28 between the left suspender band 6, the right suspender band 7 and the like.
In addition, the working machine support belt 1 includes a loop band 29 that connects the left shoulder belt 3 and the right shoulder belt 4 to each other above the back plate portion 2. According to the configuration, the working machine support belt 1 can be hooked using the loop band 29 when not in use.
Further, as illustrated in the modification example illustrated in
[Pad Member and Supporting Structure Thereof]
As illustrated in
Here, the front support band 14 and the rear support band 13 may be configured separately, or may be configured with a single band member. In a case where the front support band 14 and the rear support band 13 are configured with a single band member, the band member is folded back at the center portion 16c of the pad member 16. By configuring the front support band 14 and the rear support band 13 with a single band member, the number of components can be reduced.
As illustrated in
The cushion portion 42 includes a soft cushion portion 44 and a hard cushion portion 45 that is harder than the soft cushion portion 44, and the soft cushion portion 44 is disposed between the plate portion 41 and the hard cushion portion 45. In addition, the cushion portion 42 and the plate portion 41 are integrated by stitching the circumferential edge portions of the hard cushion portion 45 and the plate portion 41 at a plurality of locations. The plate portion 41 is made of resin, and the soft cushion portion 44 and the hard cushion portion 45 are made of sponge. In this manner, the cushion portion 42 has a two-layer structure of the soft cushion portion 44 and the hard cushion portion 45, and thus, the soft cushion portion 44 can absorb the vibration on the working machine and the hard cushion portion 45 can improve followability to the working machine. In addition, it is possible to satisfy both the vibration absorption performance and followability which are the characteristics that conflict with each other. Further, weight reduction and low cost can be realized by making the plate portion 41 with resin and making the soft cushion portion 44 and the hard cushion portion 45 with sponge.
The cushion portion 42 includes a first covering member 46 that covers the outer surface of the soft cushion portion 44, and a second covering member 47 that covers the outer surface of the hard cushion portion 45. With this configuration, deterioration of the soft cushion portion 44 and the hard cushion portion 45 is suppressed.
In addition, the cushion portion 42 includes a third covering member 48 having a substantially U-shaped section and interposing the outer edge portions of the hard cushion portion 45, the first covering member 46, and the second covering member 47, and the hard cushion portion 45, the first covering member 46, the second covering member 47, and the third covering member 48 are stitched to each other over the entire circumference. In this manner, by interposing the outer edge portions of the hard cushion portion 45, the first covering member 46, and the second covering member 47 with the third covering member 48, and by stitching the members over the entire circumference, the strength of the end portion of the hard cushion portion 45 can be improved, and the durability of the pad member 16 can be improved.
As illustrated in
As illustrated in
In the example, the front support band 14 and the rear support band 13 are stitched to the upper two stitching portions 49 among four stitching portions 49 of the hard cushion portion 45 and the plate portion 41. In this manner, by stitching the front support band 14 and the rear support band 13 in the stitching portion 49 between the plate portion 41 and the cushion portion 42, the deterioration of the design of the pad member 16 can be suppressed by forming the stitching portion between the front support band 14 and the rear support band 13.
