Description

  The present invention relates to a binding technique, and more particularly to a strap storage safety device for a strap tensioning device.

  A conventional strap tensioning device (or tensioner) is used to bind a load loaded on a transport means such as a truck in order to prevent the product from falling and being damaged when the product is transported in a place where the product is distributed. Used for.

  The structure of the conventional strap tensioning device is very simple. For example, as shown in FIG. 1, the reels 12 are arranged between the base 10 and the handle 11 and are pivotally attached to the shafts 13. A rod 14 is firmly attached to the base 10 so that the short strap 15 and the suppressor 16 can be provided therethrough. The suppressor 16 is in elastic contact with each claw 17 provided on the circumferential portion of the reel 12. A protrusion 18 is provided at the edge of the base 10, and this protrusion 18 abuts on a stopper member 19 pivotally attached to the handle 11, and each claw 17 provided on the circumferential portion of the reel 12. This prevents the stopper member 19 from coming into contact with the handle 11 and keeps the handle 11 adjacent to the base 10 and pushes the stop member 23 so that the rotation of the reel 12 is not stopped by the stop member 23. When the long strap 20 is wound around the reel 12 and an external force 21 is applied to the long strap 20 to pull it out of the base 10, the reel 12 is rotated with respect to the base 10 in the direction of the arrow. When it is opened, a beep sounds and a coil spring (not shown) is stored.

  The strap storage device of such a strap tensioning device can be selected from two types: an automatic mode and a manual mode. Please refer to FIG. As shown in FIG. 2, in the automatic mode, when the hollow portion 22 of the handle 11 is used and a force is applied to the end portion of the stopper member 19, the end portion of the stopper member 19 jumps up by the seesaw principle, and the reel The suppressor 16 is detached from each claw 17 of the 12 circumferential portions. Thereby, the reel 12 becomes a rotatable state, and the reel 12 rotates in the direction of the arrow with respect to the base 10 by the elasticity of the coil spring, so that the long strap 20 can be quickly wound.

  As shown in FIG. 3, in the manual mode, the stopper member 19 is engaged with any one claw 17 of the circumferential portion of the reel 12 beyond the protrusion 18 provided at the edge of the base 10. When the handle 11 is swung with respect to the base 10, the reel 12 rotates with respect to the base 10 in the direction of the arrow, and the long strap 20 is gradually wound up with a length equal to the pitch of the 1 to 4 claws 17. Can do. Thereafter, the handle 11 is returned to the vicinity of the protrusion 18 and reciprocated in the direction of the double arrow until the winding of the long strap 20 is completed.

  However, in the case of such a strap tensioning device, the user can only select from two types of operation modes, and there are few choices. In particular, when releasing the coil spring in the automatic winding mode, when the long strap is wound up quickly and smoothly and the start end (or hook) of the strap is pulled back by the inertial force, the strap jumps up and the operator or the surrounding work There was a risk of injury.

  Therefore, there is provided a strap storage safety device for a strap tensioning device that can reduce the risk of injury to the operator or surrounding workers when the strap is automatically wound, and can increase the options of the winding mode. It was sought after.

  Hereinafter, embodiments of the strap storage safety device of the strap tensioning device of the present invention will be described with reference to the drawings.

(First embodiment)
Please refer to FIG. 4 and FIG. As shown in FIGS. 4 and 5, the strap tensioning device 30 of the strap storage safety device of the strap tensioning device according to the first embodiment of the present invention includes a base 40, a handle 50, and a winding roller 60 that are pivotally attached to each other. Used to adjust the linear length of the short strap 31 and the long strap 32. A hook 33 connected to an end located outside the short strap 31 and the long strap 32 is hooked on a transport means such as a truck or a fixed object, and a distance between the two hooks 33 is set by a handle 50. Shrink and bind the cargo to prevent damage to the goods.

  On both sides of the base 40, bent stand pieces 41 are respectively arranged, and a stopper member 42 and a rod 43 having elasticity are arranged between the two stand pieces 41, and a strap is provided outside one of the stand pieces 41. The storage device is firmly attached. A protruding portion 44 and an end portion 45 project from the edge of each upright piece 41. The protruding portion 44 has a release strap storage area 46 recessed at one end, and a pulling operation area 47 recessed from the other end to the end portion 45. Both side portions of the stopper member 42 are respectively penetrated into the rectangular holes 48 of the upright pieces 41, and reciprocate along the hole walls by elasticity. The rod 43 is in close contact with the end of the upright piece 41, and the short strap 31 is attached to the rod 43.

  A shell 34 in which a coil spring 36 is installed is attached to the aforementioned strap storage device. One end of the coil spring 36 is fixed to the inner wall of the shell 34 so that it cannot move, and the other end is connected to the core shaft 35. Since the core shaft 35 and the take-up roller 60 operate synchronously, the take-up roller 60 can automatically collect the long strap 32 by using the coil spring 36.

  A hollow portion 51 is provided in the central portion of the handle 50, and cams 52 are provided on both sides of the handle 50. Each cam 52 is arranged in parallel to the inner surface of the upright piece 41, and a winding roller 60 is pivotally attached to the core shaft 35. A suppressor 53 is pivotally mounted between the two cams 52, and a lob 54 is provided on the periphery of each cam 52. The lobes 54 have different distances to the core shaft 35, and are provided with a stopper portion 55. The suppressor 53 is a substantially T-shaped plate, the long section 57 is located below the hollow portion 51 of the handle 50 and exposed from the hollow portion 51, and the short section 56 is the release strap storage area 46 of the two standing pieces 41. In this short section 56, two convex portions 58 project from the portion facing the winding roller 60.

  To both ends of the winding shaft 61 of the winding roller 60, a claw wheel 62 is connected. The winding shaft 61 is externally fitted to the core shaft 35 and is used for attaching a part of the long strap 32. A hole 63 is provided at the center of the claw wheel 62, and a hole wall is fitted around the core shaft 35, and the winding roller 60 that rotates around the core shaft 35 is supported by the hole wall. A plurality of claws 64 each having a radial edge 65 and a curved surface 66 are provided around the periphery of the claw wheel 62.

  The aforementioned core shaft 35 penetrates the end of the long strap 32 and is connected to the coil spring 36. The handle 50 is tilted toward the rod 43 with the core shaft 35 as the center.

  Since the suppressor 53 is constrained by the projecting portion 44, the reciprocating motion can be performed within a predetermined range of the extended release strap storage area 46, so that the handle 50 pushes the stopper member 42 by the lob 54 of the cam 52. It is moved and guided along the rectangular hole 48 and pushed backward until the stopper portion 55 comes into contact with the stopper member 42. In the suppressor 53, when the short section 56 is stretched over the upper surface of the release strap storage area 46 and is removed from the protruding portion 44, the force of the claw wheel 62 is received by the convex portion 58, and the winding roller 60 is stopped together with the coil spring 36. Maintain state. At this time, the long strap 32 receives a force and a predetermined length is pulled out along the arrow, the winding roller 60 is rotated synchronously, and the coil spring 36 is stored.

  The long strap 32 is pulled out stepwise and rotated by a predetermined angle by the take-up roller 60. In particular, the longer the length of the long strap 32 pulled out, the greater the energy stored in the coil spring 36. However, since the convex portion 58 of the suppressor 53 is located between the adjacent claws 64 and abuts against the curved surface 66 of one of the claws 64, the radial edges 65 of the adjacent claws 64 are at a predetermined distance d. Retained. The predetermined distance d is smaller than the interval between the two claws 64 adjacent to each other (hereinafter referred to as “pitch”). That is, even if the long strap 32 is fully pulled out and the stored energy of the coil spring 36 is maximized, the convex portion 58 cannot be pushed open. Therefore, kinetic energy for rotating the winding roller 60 cannot be obtained, the long strap 32 is loosened, and the rotation of the winding roller 60 is stopped.

  Please refer to FIG. One or more suppressors 53 are formed when a step is formed by tilting the handle 50 toward the base 40 until the short section 56 is released from the release strap storage area 46 and comes into contact with the protrusion 44. The convex portions 58 that are displaced between the two claws 64 and are adjacent to each other can be moved synchronously. At this time, the claw wheel 62 is displaced to a predetermined position while the curved surface 66 of the claw 64 is in close contact with the convex portion 58 due to the accumulating action of the coil spring, and the suppressor 53 is pushed open without generating a gap (or a slight distance). It will not be. Further, when the handle 50 is tilted, the stopper portion 55 is separated from the stopper member 42, and the lob 54 of the cam 52 does not stop the stopper member 42, so that the stopper member 42 is elastically attached to the claw 64 provided around the claw wheel 62. It is possible to prevent the winding roller 60 from being rotated by the long strap 32 by being touched and caught by the radial edge 65 of the claw 64. In other words, when the winding roller 60 is stopped by the stopper member 42 and the convex portion 58, the stationary state can be maintained.

  In order to explain the continuous operation in an easy-to-understand manner, the following description will be made with the A claw, the B claw, the C claw.

  As shown in FIG. 7, the winding roller 60 is brought into contact with the convex portion 58 by the curved surface 66 of the C-claw, and the suppressor 53 is moved to a predetermined position to be stopped.

  Please refer to FIG. As shown in FIG. 8, when the handle 50 receives a force and falls in the base direction, the convex portion 58 moves along the curved surface 66 of the C-claw, and the convex portion 58 reaches the tooth tip portion where the radial edge 65 intersects. Slide and the suppressor 53 rises in the direction of the arrow. The winding roller 60 (or the ratchet wheel 62) cannot be rotated counterclockwise as shown in the drawing even though the convex portion 58 comes into contact with the curved surface 66 and friction is generated. It is only pushed along.

  Next, refer to FIG. As shown in FIG. 9, when the displacement of the handle 50 continues to increase, the convex portion 58 moves away from the C-claw, the contact action of the suppressor 53 against the claw wheel 62 is lost, and the stopper member 42 is as shown in FIG. And the take-up roller 60 is not locked, the coil spring reacts quickly to the take-up roller 60 and rotates the claw wheel 62 at the depression angle θ. Abutted and pushes open the suppressor 53 in the direction of the arrow. As a result, the suppressor 53 is restored by accumulating, the A claw rotated to the same angle is pushed open, and this cycle is repeated. By rotating the claw wheel 62 a plurality of times, the suppressor 53 is continuously pushed and opened by the claw 64 provided in the periphery, and a part of the strap is wound up. When the suppressor 53 jumps and comes into contact with the take-up roller 60, the rotational kinetic energy is gradually canceled and balanced, and the convex portion 58 is positioned between the adjacent claws 64 so that the take-up roller 60 rotates. Stop and stop the strap winding operation.

  The longer the long strap is pulled out, the greater the energy stored in the coil spring, the greater the number of rotations of the take-up roller 60, and the longer strap that is automatically taken up naturally becomes longer. On the other hand, when the length for pulling out the long strap is not long, the rotation speed of the winding roller 60 becomes slow. In this case, the rest of the strap may be wound up by the following steps.

  Please refer to FIG. As shown in FIG. 10, when the long section 57 of the suppressor 53 is pressed using the hollow portion 51 of the handle 50, the short section 56 jumps up and protrudes from the claw wheel 62 corresponding to the curved surface 66 of the claw 64. The part 58 leaves | separates and the remaining long strap 32 is wound up in the arrow direction by the remaining accumulating of the coil spring. As a result, the hook 33 does not jump up due to inertia, and the safety of the operator or surrounding workers can be ensured.

  Next, refer to FIG. 11 and FIG. As shown in FIGS. 11 and 12, when the handle 50 is tilted in the manual mode and the strap is wound, the suppressor 53 is arranged so as to be passed over the protruding portion 44 by the short section 56 to the pulling operation area 47, The handle 50 can be swung only between the protrusion 44 and the end 45. The short section 56 abuts against the radial edge 65, rotates the take-up roller 60 by the width of one or more claws 64, and slowly takes up and stores the pulled-out long strap 32.

(Second Embodiment)
Reference is made to FIGS. As shown in FIGS. 13 to 15, the strap storage safety device for the strap tensioning device according to the second embodiment of the present invention is that the short section 56 of the suppressor 53 is not provided with a convex portion. And different.

  In actual use, the C-shaped curved surface 66 is held down by the short section 56 and the winding roller 60 is kept stationary. When the handle 50 is tilted by receiving a force, the short section 56 slides to the tooth tip along the C-shaped curved surface 66, and pushes the suppressor 53 in the direction of the arrow. If the handle 50 is continuously pressed, the short section 56 is disengaged from the C-claw and the take-up roller 60 rotates at a high speed, and each claw 64 provided around the claw wheel 62 continuously hits the short section 56 and winds. A portion of the long strap continues to be wound until the rotational kinetic energy of the take-up roller 60 is gradually offset by the short section 56 and winding of the long strap by the take-up roller 60 is stopped.

  As can be seen from the above, the strap tensioning device of the present invention includes the following strap storage systems (1) to (3).

(Manual method)
(1) Oscillating strap storage: Using a suppressor, the swinging range of the handle is constrained within the pulling operation area, the winding roller is rotated within a predetermined range, and the pulled long strap is slowly wound.

(Automatic method)
(2) Strap storage by a single turn: The movable range of the handle that is tilted toward the base using the suppressor is limited to the release strap storage area, and the suppressor is pressed using the hollow portion of the handle to When the resistance force is released, all the stored energy of the coil spring is released at a time, and the long strap is wound up by the winding roller.

  (3) Strap storage by multiple times: The range of swinging the handle using the suppressor is limited to the release strap storage area, the suppressor jumps and contacts the take-up roller, and the rotational kinetic energy is offset by the suppressor. Until the rotation stops, wind up a part of the long strap and perform the first strap automatic storage step. When you press the suppressor using the hollow part of the handle to release the resistance of the take-up roller, the remaining energy of the coil spring is released, and the second strap automatic is taken up by the take-up roller to take up the remaining long strap. Perform the storage step.

  Among the three types of strap storage modes described above, the function of (3) is one because the strap can be stored quickly and safely and the safety of the operator or surrounding workers can be ensured. Most preferred.
