Description

Technical Field

[0001] This invention relates to a safety device; more particularly to a rope gripper for securing a rope. Prior Technology

[0002] Existing rope grippers are designed to be used with a safety rope. The housing of the rope gripper has a rope groove, and a claw wheel is provided near the rope groove. When the rope gripper is in use, the safety rope is placed in the rope groove, and the claw wheel contacts the safety rope to guide the safety rope to slide unidirectionally along the rope groove. In addition, when the rope gripper falls rapidly, the claw wheel can cooperate with the wall of the rope groove to clamp the safety rope, thereby providing a safety protection effect for the user.

[0003] However, conventional rope grippers have openings at both ends that connect to the rope groove. When using them, the user must align the safety rope and thread it through one opening, and then through the other opening to place the safety rope into the rope groove. The structure of conventional rope grippers is not conducive to the installation and removal of safety ropes. Therefore, how to provide a rope gripper that facilitates the installation and removal of safety ropes is an urgent problem to be solved. Summary of the Invention

[0004] In view of this, the purpose of the present invention is to provide a rope gripper that facilitates the installation and removal of ropes by the user.

[0005] To achieve the above objectives, the present invention provides a rope gripper for accommodating a rope body, comprising a housing, a claw wheel, a resilient switch, a stop member, and a cover. The housing has a rope groove for accommodating the rope body, and the rope groove has an opening on one side. The claw wheel is disposed in the housing and adjacent to the rope groove, and the claw wheel can cooperate with the rope groove to clamp or guide the rope body inserted into the rope groove. The resilient switch includes a body and a resilient member, one end of the resilient member abutting against the housing, and the other end abutting against the side of the body facing the housing. The body can move between a starting position and a pressing position. The body and the housing together form a channel, the channel having a first section and a second section, the inner diameter of the first section being larger than the inner diameter of the second section. The stop member is movably disposed in the channel. When the stop member is located in the first section, the body can be moved from the starting position to the pressing position under force. When the stop member is located in the second section, the body can move from the starting position to the pressing position under force. The cover is positioned in the first segment, where the main body is restricted by the stop member and cannot move to the pressed position. The cover has a locking hole and is movably disposed in the housing. When the stop member is in the first segment, the cover can move between a first position and a second position. When the cover is in the first position, the side opening of the rope groove is open. During the movement of the cover from the first position to the second position, the cover contacts and presses against the elastic switch, causing the elastic switch to move to the pressed position. When the cover is in the second position, the elastic switch is in the locking hole, so that the cover does not press against the elastic switch and returns to the starting position, and the cover closes the side opening. When the stop member is in the second segment, the main body is restricted by the stop member and cannot move to the pressed position, so that the main body is on the movement path of the cover and restricts the cover from moving from the first position to the second position or from the second position to the first position.

[0006] The advantage of this invention is that, through the design of the cover being movable between the first position and the second position to open or close the side opening of the rope groove, it is convenient for the user to install or remove the rope from the rope gripper; in addition, the setting of the stop member can prevent the user from accidentally touching the elastic switch and opening the cover, thereby improving the safety of the rope gripper.

[0008] To more clearly illustrate the present invention, preferred embodiments are described in detail below with reference to the accompanying drawings. Referring to Figures 1 to 11, a preferred embodiment of the rope gripper 1 of the present invention is shown. The rope gripper 1 is used to hold a rope body R. The rope gripper 1 includes a housing 10, a claw wheel 20, an elastic switch 30, a stop member 40, and a cover 50. The housing 10 has a rope groove 12 for accommodating the rope body R. The rope groove 12 has an opening 121 on one side. The claw wheel 20 is disposed in the housing 10 and adjacent to the rope groove 12. The claw wheel 20 can cooperate with the rope groove 12 to clamp or guide the rope. The rope R, which is inserted into the rope groove 12, for example, as shown in Figure 4, when the rope R is placed in the rope groove 12, the friction between the claw wheel 20 and the rope R can drive the claw wheel 20 to rotate, thereby guiding the rope gripper 1 to move unidirectionally relative to the rope R. When the braking device of the rope gripper is locked, the claw wheel 20 can push the rope R to cooperate with the groove wall of the rope groove 12 to clamp the rope R, so that the rope gripper 1 cannot move relative to the rope R, thereby achieving the effect of braking and stopping the fall.

[0009] Please refer to Figures 1 and 2. The cover 50 is pivotally mounted on the housing 10 in a movable manner. The cover 50 can pivot between a first position P1 and a second position P2.

[0010] As shown in Figure 5, the elastic switch 30 includes a body 32 and an elastic element 34. In this embodiment, the elastic element 34 is described as a compression spring. One end of the elastic element 34 abuts against the housing 10, and the other end abuts against the side of the body 32 facing the housing 10. Thus, through the deformation of the elastic element 34, the body 32 can move between a starting position A1 and a compressed position A2. When the elastic element 34 is not deformed by force, the body 32 is located at the starting position A1. When the elastic element 34 is compressed by force, the body 32 is located at the compressed position A2. The body 32 and the housing 10 together form a channel C. The channel C has a first segment C1 and a second segment C2. The inner diameter of the first segment C1 is larger than the inner diameter of the second segment C2.

[0011] Please refer to Figure 5. The stop 40 is movably disposed in the channel C. When the stop 40 is located in the first segment C1, the body 32 can be compressed by the elastic member 34, thereby moving the body 32 from the starting position A1 to the pressing position A2. When the stop 40 is located in the second segment C2, the body 32 is restricted by the stop 40 and cannot move to the pressing position A2. In this embodiment, the stop 40 is described as a sphere. In other embodiments, it is not excluded that the stop is a component of other shapes.

[0012] Furthermore, the cover 50 has a through-hole 52, the outline of which matches the outer outline of the body 32. When the stop 40 is located in the first segment C1, the cover 50 can move between the first position P1 and the second position P2. When the stop 40 is located in the first segment C1 and the cover 50 is located in the first position P1, the side opening 121 of the rope groove 12 is open. When the stop 40 is located in the first segment C1 and the cover 50 moves from the first position P1 to the second position P2, the cover 50 contacts and presses against the elastic switch 30, causing the body 32 to compress the elastic member 34, thereby causing the elastic switch 30 to move to the pressed position A2. When the stop 40 is located in the first segment C1 and the second position P2, the cover 50 contacts and presses against the elastic switch 30, causing the body 32 to compress the elastic member 34, thereby causing the elastic switch 30 to move to the pressed position A2. When the cover 50 is in the second position P2, the body 32 of the elastic switch 30 is located in the engaging hole 52 and protrudes from the engaging hole 52. At this time, the cover 50 does not press against the body 32 of the elastic switch 30, that is, the elastic switch 30 is not subjected to pressure. This causes the elastic member 34 to release the compressed stored energy, causing the body 32 to return to the initial position A1 and the cover 50 to close the side opening 121. When the stop member 40 is in the second segment C2, the body 32 is restricted by the stop member 40 and cannot move to the pressed position A2. This causes the body 32 to be located on the movement path of the cover 50, restricting the cover 50 from moving from the first position P1 to the second position P2 or from the second position P2 to the first position P1.

[0013] For example, when a user wants to open the cover 50 to install or remove the rope R from the rope gripper 1, if the rope gripper 1 remains upright, as shown in Figure 5, the stop 40 will fall into the first section C1 of the channel C due to gravity. At this time, when the user presses the side of the body 32 facing away from the housing 10, the body 32 will compress the elastic member 34 as shown in Figure 6, causing the body 32 to move to the pressed position A2, thus disengaging the body 32 from the engaging hole 52 of the cover 50 and leaving the movement path of the cover 50. Then, the user can move the cover 50 from the second position P2 to the first position P1 as shown in Figure 8, thereby opening the side opening 121 of the rope groove 12 to facilitate... The user installs or removes the rope body R from the rope groove 12. Furthermore, if the rope gripper 1 is not kept upright, for example, in an inverted state as shown in Figure 9, the stop 40 will fall into the second section C2 of the channel C due to gravity. At this time, even if the user presses the body 32, the stop 40, sandwiched between the body 32 and the housing 10, prevents the body 32 from compressing the elastic member 34 and causing displacement. The body 32 remains engaged with the locking hole 52 of the cover 50, preventing the cover 50 from pivoting relative to the housing 10. This ensures that the cover 50 of the rope gripper 1 can only be opened under appropriate operating conditions, thereby improving the safety of the rope gripper 1.

[0014] Conversely, when the user wants to close the cover 50, if the rope gripper 1 remains upright, as shown in Figure 8, the stop 40 will fall into the first section C1 of the channel C due to gravity. At this time, when the user presses the side of the body 32 opposite to the housing 10, the body 32 will compress the elastic member 34, causing the body 32 to move to the pressed position A2. Then, the user can move the cover 50 from the first position P1 to the second position P2, thereby closing the side opening 121 of the rope groove 12. It should be further noted that... If the rope gripper 1 is not kept upright, for example, when it is upside down, the stop 40 will fall into the second section C2 of the channel C due to gravity. At this time, even if the user presses the body 32, the body 32 cannot compress the elastic member 34 and move to the pressed position A2 because the stop 40 is clamped between the body 32 and the housing 10. This makes the body 32 located on the movement path of the cover 50, and the cover 50 cannot move relative to the housing 10 from the first position P1 to the second position.

[0015] Further explanation is provided in Figures 10 and 11. The housing 10 has a first groove 14, and the body 32 has a second groove 321. The second groove 321 of the body 32 and the first groove 14 of the housing 10 together form the first segment C1 of the channel C. As shown in Figures 1 and 2, the rope gripper 1 includes a limiting member 60 disposed on the housing 10. The cover 50 has a hook 54. When the cover 50 is in the first position P1, the limiting member 60 disengages from the hook 54. When the cover 50 is in the second position P2, the limiting member 60 abuts against the hook 54. The limiting member 60 includes a body 62 and a head 64. One end of the body 62 is connected to... The housing 10 is connected, and the other end of the body 62 is connected to the head 64. The outer diameter of the head 64 is larger than the outer diameter of the body 62. When the cover 50 is in the second position P2, the hook 54 abuts against the body 62 and the hook 54 is located between the head 64 and the housing 10. In addition, when the cover 50 pivots between the first position P1 and the second position P2, the outer edge of the cover 50 can move in the space between the head 64 and the housing 10, thereby restricting the movement path of the cover 50 and preventing the cover 50 from flipping outward relative to the housing 10 and crossing the body 32. In addition, the design of the hook 54 abutting against the body 62 can restrict the end point of the movement path of the cover 50.

[0016] Furthermore, as shown in Figure 11, the body 32 has a groove 322 on one side facing the housing 10. The elastic member 34 is at least partially accommodated in the groove 322 and abuts against the bottom of the groove 322, thereby ensuring that the elastic member 34 is securely disposed in the body 32. In addition, as shown in Figure 5, the housing 10 has a communicating accommodating space 101 and an opening 102. The elastic member 34 and the body 32 are accommodated in the accommodating space 101. The body 32 has a first part 323 and a second part 324 connected to each other. The second part 324 has an annular protrusion. When the body 32 is in the initial position A1, the first part 323 protrudes from the opening 102, and the annular protrusion of the second part 324 abuts against the opening 102 to prevent the body from falling off.

[0017] Further explanation is provided in Figure 5. One side of the body 32 of the elastic switch 30 has a guide slope 325. This guide slope 325 is located on the side of the body 32 opposite to the housing 10. Thus, during the movement of the cover 50 from the first position P1 to the second position P2, the cover 50 contacts the guide slope 325 and presses against the elastic switch 30, causing the elastic switch 30 to move to the pressed-down position A2. In addition, the elastic switch 30 also has a flat surface 326, and on the other side of the elastic switch 30 opposite to the guide slope 325, it has another guide slope 327. The flat surface 326 is disposed on... Between the guide slope 325 and the other guide slope 327, during the movement of the cover 50 from the first position P1 to the second position P2, the cover 50 contacts the guide slope 325 and presses against the elastic switch 30. Then, the cover 50 can continue to move towards the second position P2 along the plane 326. When the cover 50 moves from the second position P2 to the first position P1, the cover 50 can contact the other guide slope 327 and press against the elastic switch 30, thereby guiding the cover 50 to smoothly contact and press against the body 32 of the elastic switch 30, thereby improving the user's operating feel.

[0018] In summary, the advantages of this invention are that, through the design of the cover 50 being movable between the first position P1 and the second position P2 to open or close the side opening 121 of the rope groove 12, it is convenient for the user to install or remove the rope R from the rope gripper 1; in addition, the setting of the stop member 40 can prevent the user from accidentally touching the elastic switch 30 and opening the cover 50, thereby improving the safety of the rope gripper 1; furthermore, through the setting of the guide slope 325 on one side of the elastic switch 30, the cover 50 can be guided to smoothly contact and press against the elastic switch 30, improving the user's operating feel.
