[Technical Field]

[0001] The present invention relates to a shock absorber for a full harness that is attached to a full harness when used. [Background technology]

[0002] When working at heights, such as at a building construction site, safety harnesses are used to prevent falls. A safety harness typically consists of a full harness worn around the worker's body and a lanyard that is connected to the full harness and has a hook for connecting to supports such as lifelines or scaffolding handrails.

[0003] Conventionally, such safety belts have been known to have a shock absorber between the lanyard and the full harness to reduce the impact on the worker's body when the worker falls from a high place, such as scaffolding at a construction site.

[0004] For example, Patent Document 1 describes a shock absorber that has a buffer body made by sewing together multiple folded buffer belts with binding thread, a connecting loop for connecting a lanyard provided at one end of the buffer belt, and a connecting loop for connecting a full harness provided at the other end of the buffer belt, with each connecting loop provided at the upper end of the buffer body, and the buffer body being stored in a pocket located below the center of the worker's back.

[0014] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A shock absorber for a full harness according to an embodiment of the present invention will be described below with reference to the drawings.

[0015] A shock absorber 1 for a full harness (hereinafter, sometimes referred to as “shock absorber 1”) according to one embodiment of the present invention constitutes a part of a safety belt 10.

[0016] As shown in Figures 1 and 2, safety belt 10 is fitted to at least torso 12 of worker 11 and includes a full harness (waist belt) 13 for holding worker 11 in the event of a fall, and a lanyard (lifeline) 15 equipped with a hook 14 for connecting full harness 13 to a safety block installed at a high place when ascending or descending vertically, or for connecting to a support such as a lifeline or scaffolding handrail installed at a high place. In this embodiment, safety belt 10 is a double lanyard type equipped with two lanyards 15. Shock absorbers 1 are connected between full harness 13 and each lanyard 15 to reduce the impact on worker 11's body when worker 11 falls from a high place such as scaffolding at a construction site.

[0017] The full harness 13 can be wrapped around the waist, chest, thighs, back, shoulders, etc. of the worker 11. A connection part 16 for connecting the shock absorber 1 is provided on the part of the full harness 13 that extends vertically on the back of the worker 11, located slightly below the shoulders. The connection part 16 is made up of, for example, a ring-shaped metal fitting. The ring shape can be, for example, a circular ring, a D-shape, a rectangular ring, or a triangular ring.

[0018] Each of the two lanyards 15 has a reel 17, with a portion of the lanyard 15 being pulled out from the reel 17. The remaining portion of the lanyard 15 is wound around the reel 17, and can be pulled out from the reel 17 by pulling the lanyard 15. By pulling out the remaining portion of the lanyard 15 from the reel 17, the worker 11 can easily grasp the hook 14 with his or her hand. Meanwhile, the pulled-out lanyard 15 is automatically wound into the reel 17 by letting go of the reel. Alternatively, the lanyard 15 can be freely unwound from the reel 17 following the worker's movements, and can be stored in the reel 17 by simply pulling it slightly at any desired position when wound up. The hook 14 is attached to the tip of the lanyard 15. The hook 14 can be configured, for example, as a large-diameter hook, and can be easily attached to and detached from supports such as life ropes and scaffolding handrails.

[0019] The full harness 13 can have portable items 18, such as a tool holder, a waist bag, and a tool hook, attached to the belt portion that is wrapped around the waist of the worker 11. The portable items 18, such as the tool holder, the waist bag, and the tool hook, can store various tools.

[0020] As shown in FIGS. 3 and 4, the shock absorber 1 includes a buffer body 20, a first connecting portion 21, and a second connecting portion 22.

[0021] The buffer body 20 is formed by sewing together multiple folded buffer belts 23 with a stitching thread. The buffer body 20 has an elongated rod-like shape overall and is housed in a breakable cover 24. The cover 24 is preferably made of resin or cloth with a strength sufficient to withstand a load of 150 kg or more. A bypass belt 25, consisting of two belts joined in a cross shape, is joined and stitched with a stitching thread between the folded portion at one end of the buffer belt 23 and the folded portion at the other end of the buffer belt 23. The bypass belt 25 is folded together with the buffer belt 23 in multiple layers and sewn together with the buffer belt 23 with a stitching thread to form part of the buffer body 20. The buffer body 20 is configured to be separable when the weight of the worker 11 is applied, cutting the stitching thread at the overlapping portions of the buffer belt 23 and the bypass belt 25.

[0022] The first connecting portion 21 is for connecting a lanyard, and is provided on one end side of the buffer belt 23. In this embodiment, the first connecting portion 21 is supported by a pin member 26 attached in a state where it is hooked onto the folded portion on one end side of the buffer belt 23, and is rotatably connected to the one end side of the buffer belt 23 via the pin member 26.

[0023] The second connection portion 22 is for connecting a full harness, and is provided on the other end 28 of the buffer belt 23. The folded portion of the other end 28 of the buffer belt 23 protrudes from the cover 24. In this embodiment, the second connection portion 22 is supported by a pin member 27 attached in a state where it is hooked onto the folded portion of the other end 28 of the buffer belt 23, and is rotatably connected to the other end of the buffer belt 23.

[0024] In this way, the shock absorber 1 is configured such that the first connection part 21 for connecting a lanyard and the second connection part 22 for connecting a full harness are each provided on one end side of the longitudinal direction of the buffer body 20, i.e., both are on the same side.

[0025] The shock absorber 1 is attached by connecting the second connection part 22 to the connection part 16 of the full harness 13 attached to the worker 11, so that the first connection part 21 and the second connection part 22 are positioned at the longitudinal ends of the buffer body 20 facing upward. When the shock absorber 1 is attached to the full harness 13, the first connection part 21 is positioned above the upper back of the worker 11, i.e., above the center of the back in the vertical direction.

[0026] With the shock absorber 1 of this embodiment having such a configuration, the shock absorber 1 can be attached to the full harness 13 via the second connection part 22 for connecting to the full harness, while the first connection part 21 for connecting the lanyard can be positioned on the upper back of the worker 11. This makes it less likely that the lanyard 15 connected to the buffer 20 via the first connection part 21 will get caught on the portable item 18 worn around the waist of the worker 11 or on tools or the like stored in the portable item 18. This makes it easier to take tools or the like in and out of the portable item 18, and also makes it easier to handle the lanyard 15.

[0027] Here, in the shock absorber 1 of this embodiment, the first connection part 21 for connecting a lanyard and the second connection part 22 for connecting a full harness are each provided at one end side in the longitudinal direction of the buffer body 20, so the buffer body 20 needs to be configured so that both the one end side of the buffer belt 23 where the first connection part 21 is provided and the other end side of the buffer belt 23 where the first connection part 21 is provided are disposed at one end side. Therefore, the challenge is to ensure that the buffer body 20 is strong enough to withstand the impact of a fall and is compact.

[0028] In response to this problem, in the shock absorber 1 of this embodiment, as shown in FIG. 5, a portion of the bypass belt 25 is folded in half and wound between the folded portion on one end side and the folded portion on the other end side of the buffer belt 23, and another portion of the bypass belt 25 is folded in half between the middle portion of the buffer belt 23 and then folded in thirds. The portion extending from the other end side of the buffer belt 23 is made to run along the periphery of the folded portion of the bypass belt 25, and then the portion extending from one end side and the portion extending from the other end side of the buffer belt 23 are wound around the folded portion of the bypass belt 25 to further cover it from the outside, thereby folding the buffer belt 23 and the bypass belt 25 multiple times as shown in FIG. 5, and in this state, the buffer belt 23 and the bypass belt 25 are sewn together with a stitching thread passed in the folding direction.

[0029] The buffer body 20 configured by folding the buffer belt 23 and the bypass belt 25 multiple times as described above has a symmetrical rod-like shape in the cross section shown in FIG. 5, and its external shape is compact.

[0030] In addition, in the shock absorber 1 of this embodiment, the buffer belt 23 and the bypass belt 25 are folded multiple times as described above to make the buffer body 20 compact, while the sewing pattern of the binding thread, the thickness of the binding thread, the number of binding threads, and the number of twists of the binding thread are improved to ensure the buffer body 20's strength against the impact of a fall.

[0031] For example, in the shock absorber 1 of this embodiment, the buffer body 20 is made of the buffer belt 23 and the bypass belt 25, which are made of 120 warp threads made of nylon with a count (thickness) of 940 dtex and twisted at a twist coefficient of 4 (turns / inch) and are formed into a width of 33 mm, and the buffer belt 23 and the bypass belt 25 are folded in multiple layers as described above and sewn together in a predetermined high-density sewing pattern with 40 polyester binding threads with a count (thickness) of 1110 dtex.

[0032] This allows the buffer 20 to have a compact external shape while increasing the amount of impact it can absorb each time the binding thread is cut to a desired level and setting its strength to an appropriate level that ensures a drop impact value below the standard value, thereby ensuring the safety of the shock absorber 1. For example, the drop impact value of the buffer 20 configured as described above is a maximum of 4.06 kN and an average of 3.69 kN, which are below the standard values ​​of 8 kN and 4 kN, respectively. Furthermore, the amount of extension of the buffer 20 is 720 mm, which is below the JIS standard value of 1200 mm.

[0033] In contrast, when the buffer 20 is configured by changing only the number of binding threads to 33, the drop impact value of the buffer 20 is a maximum of 3.36 kN and an average of 2.98 kN, and the drop impact value per hour is lower compared to when the number of binding threads is 40, so the time to absorb the total impact force is longer, the amount of elongation is 1050 mm, and the drop distance is too long. Also, when the buffer 20 is configured by changing the warp twist coefficient to 3 (turns / inch), the binding thread count to 1100 dtex, the number of binding threads to 33, and the binding thread stitching pattern is made lower density, the drop impact value of the buffer 20 is a maximum of 3.03 kN and an average of 2.76 kN, and similarly the drop impact value per hour is lower, so the time to absorb the total impact force is longer, and the amount of elongation is 1240 mm, which is outside the standard range of the JIS standard, and the drop distance is too long.

[0034] As shown in FIG. 3, in the shock absorber 1 of this embodiment, the first connecting portion 21 is formed with a pair of protruding portions 21a that protrude in a direction perpendicular to the longitudinal direction of the buffer 20. More specifically, as shown in FIG. 6, the first connecting portion 21 has a pair of parallel, plate-like leg portions 21b fixedly supported by a pin member 26. The first connecting portion 21 has ratchet teeth on the outer edges of the pair of legs 21b. When the pin member 26 is rotated along the rotation axis, the ratchet teeth come into contact with a locking pawl that locks the ratchet teeth. The first connecting portion 21 may also be configured with an opening / closing angle adjustment mechanism that can be set to any angle around the rotation axis, allowing it to be adjusted to an angle that is convenient for work and storage. The pair of protruding portions 21a protrude outward in the width direction from the upper ends of the pair of legs 21b. In the case shown in FIG. 6, the pair of protruding portions 21a are curved in an arc shape that convex outward in the width direction. The upper ends of the pair of overhanging portions 21a are connected by a connecting side portion 21c that is slightly curved so as to be convex upward. In this way, the first connecting portion 21 has an overall mushroom-like shape.

[0035] The connecting side 21c has a rib 21d that protrudes downward to increase its strength. As shown in Fig. 4, the first connecting portion 21 extends obliquely upward relative to the buffer body 20.

[0036] On the other hand, the reel 17 of the lanyard 15 connected to the first connection part 21 has a connecting fitting 17a shown in FIG. 7. The connecting fitting 17a is configured such that a pair of legs 17c are embedded and supported within the case body 17b of the reel 17 at a width equal to or 1.5 times wider than the connecting fitting 17a. This increases the fixing strength of the connecting fitting 17a to the case body 17b. The portion of the connecting fitting 17a protruding from the case body 17b has an arc shape with a radius that allows it to be connected to the first connection part 21, and a reinforcing rib 17d is provided on its inner peripheral surface. The portion of the connecting fitting 17a protruding from the case body 17b is hooked onto the first connection part 21, thereby connecting the connecting fitting 17a to the first connection part 21.

[0037] To connect the connecting fittings 17a to the first connecting portion 21 and improve workability, the first connecting portion 21 is preferably composed of a large ring with a radius of 30 mm to 300 mm, and the connecting fittings 17a have a radius of 20 mm to 30 mm. The two connecting fittings 17a are designed to be freely movable on the first connecting portion 21 and can be stopped at any location when stationary. Furthermore, for stable holding, an arc-shaped protruding portion 21a that protrudes outward in the width direction of the first connecting portion 21 can be provided. By providing the protruding portion 21a, when the right hook is pulled to the left, the winder 17 held by the protruding portion 21a smoothly flips to the left and waits stationary at the connecting edge 21c.

[0038] As described above, in shock absorber 1 of this embodiment, first connection portion 21 is shaped to have a pair of protruding portions 21a that each protrude in a direction perpendicular to the longitudinal direction of buffer 20. Therefore, compared to a case in which first connection portion 21 does not have a pair of protruding portions 21a, the movable range of lanyard 15 connected to first connection portion 21 is expanded so that it can move diagonally downward, improving workability when worker 11 wearing safety belt 10 turns left and right without interference from pair of lanyards 15. Because reel 17 can be stably held by protruding portions 21a when stationary, reel 17 does not come into contact with the upper part of shock absorber 1 for full harness, preventing damage to components.

[0039] In particular, in the safety belt 10 configured such that two lanyards 15 each equipped with a reel 17 are connected to the first connection part 21 as in this embodiment, if the first connection part 21 does not have a pair of protruding parts 21a, the reel 17 will not be able to move freely along the first connection part 21, and the two reels 17 may cross each other, which may impair the workability of the worker 11 wearing the safety belt 10.

[0040] In contrast, in the shock absorber 1 of this embodiment, the first connection portion 21 is shaped to include a pair of protruding portions 21a that protrude in a direction perpendicular to the longitudinal direction of the buffer body 20. This allows the two reels 17 connected to the first connection portion 21 to move freely back and forth and left and right, and to rotate and reverse, improving the workability of the worker 11 wearing the safety belt 10. Furthermore, the width of the metal ring of the first connection portion 21 is preferably 12 mm to 20 mm to ensure strength. Furthermore, the radius of the arc is preferably 100 mm to 150 mm. This shape improves the workability of the worker 11 wearing the safety belt 10, eliminating the need for an increase in the number of parts and allowing the safety belt 10 to be made lighter. Furthermore, even if both of the two reels 17 move toward one of the protruding portions 21a, they can remain at the first connection portion 21, preventing the worker 11's center of gravity from shifting to one side due to this movement, allowing the worker 11 to work safely.

[0041] In the shock absorber 1 of this embodiment, the radius of the arc-shaped protruding portion 21a of the first connecting portion 21 is preferably 7 mm to 15 mm. This allows the two reels 17 connected to the first connecting portion 21 to move without getting caught on the protruding portion 21a. Furthermore, the radius of the arc-shaped protruding portion 21a is more preferably 7.5 mm to 10 mm. Furthermore, it is preferable that the protruding portion 21a protrudes 8 mm to 15 mm from the main body of the shock absorber 1 for a full harness. This allows the two reels 17 connected to the first connecting portion 21 to move more smoothly without getting caught on the protruding portion 21a.

[0042] In the shock absorber 1 of this embodiment, the radius of the connecting fitting 17a that connects to the first connecting part 21 is preferably 20 mm to 30 mm. In addition, the width of the metal ring is preferably 14 mm to 25 mm to ensure strength. This allows the first connecting part 21 to move freely back and forth and left and right, and to rotate and reverse, improving the workability of the worker 11 wearing the safety belt 10.

[0043] As shown in FIG. 4, the first connection part 21 extends obliquely upward relative to the longitudinal direction of the buffer body 20. The angle of inclination of the first connection part 21 relative to the longitudinal direction of the buffer body 20 is preferably 30 to 60 degrees in the direction away from the back. This allows the two reels 17 connected to the first connection part 21 to move forward, backward, left, right, and rotate more freely. On the other hand, if the angle of inclination of the first connection part 21 relative to the longitudinal direction of the buffer body 20 is greater than 60 degrees (e.g., 90 degrees), the reels 17 can move and rotate freely. However, the two reels 17 are not stably held with the protruding parts 21a in the standby position, and the reels 17 move constantly. In addition, the protruding height of the first connection part 21 from the back increases, which may impair safety and convenience during operation. Conversely, if the inclination angle of the first connection portion 21 relative to the longitudinal direction of the buffer body 20 is less than 30 degrees (for example, 0 degrees), the two reels 17 can be stably held in a standby position consisting of the protruding portion 21a, but movement and rotation of the reels 17 becomes difficult.

[0044] The shape of the first connecting portion 21 having a pair of protruding portions 21a is not limited to the shape shown in FIG. 6, and various other shapes are possible, such as a shape as shown in FIG. 8 in which the radius of the lower half of the protruding portion 21a connected to the leg portion 21b is larger than the radius of the upper half connected to the connecting side portion 21c; a shape as shown in FIG. 9 in which a recessed portion 21e that is narrowed inward in the width direction is provided between the protruding portion 21a and the leg portion 21b, so that the protruding portion 21a reaches further inward than the leg portion 21b; a shape as shown in FIG. 10 in which a C-shaped notch is provided in a substantially rectangular plate material and the protruding portion 21a is formed by the outer portion of the notch; and a shape as shown in FIG. 11 in which an anti-slip structure is provided on the pair of protruding portions 21a and the pair of protruding portions 21a and the connecting side portion 21c are continuously connected at the same radius to form a circle overall.

[0045] Furthermore, the shape of the first connection part 21 having a pair of protruding parts 21a can also be a shape provided with a plurality of protruding parts 21a, such as two or three, as shown in Fig. 12. In this case, the lengths of the protruding parts 21a may be the same or different. With this configuration, the plurality of winders 17 do not become tangled, and damage to the case body 17b due to a collision can also be prevented.

[0046] Furthermore, the shape of the first connection part 21 having a pair of protruding parts 21a can be such that the protruding parts 21a are configured as a deep bag, as shown in Figure 13, which can hold the stationary position of the winder 17 more firmly than shallower protruding parts 21a and prevent lateral rattle.

[0047] Furthermore, the shape of the first connection part 21 having a pair of protruding parts 21a can be such that two of the above-mentioned shapes are arranged in parallel with the legs 21b installed separately or integrated, as shown in an example in Figure 14. By using a shape with two first connection parts 21, the range in which each reel 17 can move freely is wide, and space for connecting safety blocks can also be secured.

[0048] As shown in FIG. 3 , the buffer 20 may also be configured with fixing portions 30 that temporarily fix the buffer 20 to the full harness 13. In this embodiment, the fixing portions 30 are strip-shaped hook-and-loop fasteners fixed to the case body 17b of the buffer 20 at a longitudinally intermediate portion thereof, and are provided at two locations, one above and one below, the buffer 20. By wrapping and fixing these fixing portions 30 around the portion of the back of the full harness 13 that extends in the vertical direction, the shock absorber 1, which is suspended and held by the full harness 13 at the second connection portion 22, can be temporarily fixed to the full harness 13. This prevents the shock absorber 1 from jumping up from the back of the worker 11 while the worker 11 is working.

[0049] The fixing portion 30 may be configured to be fixed to the back surface of the case body 17b and wrapped around only the full harness 13, or may be configured to be fixed to the front surface of the case body 17b and wrapped around the buffer body 20 and the full harness 13 together.

[0050] By using a hook-and-loop fastener as the fixing portion 30, it is possible to reduce the number of fixing portions 30. Note that the fixing portion 30 is not limited to a hook-and-loop fastener, and may be configured to be temporarily fixed to the full harness 13 using other members such as a button, a magnet, a clip, or a hook.

[0051] The buffer 20 that constitutes the shock absorber 1 can be processed to improve fire resistance, to take measures against static electricity such as by mixing in conductive fibers, to improve stain resistance such as by applying paint, to improve dust resistance (particle dust resistance), to improve water repellency, or to improve antibacterial and odor resistance.

[0052] Although the above description has been given based on the illustrated examples, the present invention is not limited to the above-described embodiments and can be modified as appropriate within the scope of the claims.

[0053] For example, the folding method of the buffer belt 23 and the bypass belt 25 that constitute the buffer body 20 is not limited to the folding method shown in FIG. 5, and can be changed in various ways. [Explanation of symbols]
