Description

Pet Tractor Leash Safety Device

[0001] The present invention relates to a leash safety device for a pet traction device that allows the user to set the leash extension length in various modes through simple operation.

[0002] As you know, the number of households with pets is increasing, and as a result, there are many cases of taking pets out. At these times, a leash that can be worn around the pet's neck and the owner can hold the leash to limit the pet's range of movement.

[0003] Meanwhile, as illustrated in Fig. 1, a conventional general pet traction device (10) automatically pulls out the lead (30) wound on a reel (20) according to the pet's activities through a spiral spring method, and restricts the pulling out of the lead through a button-type locking device (40).

[0004] In the case of this spiral spring method, the user must observe carefully from time to time, and the locking device (40) is controlled by pressing the button of the locking device (40) to brake the leash (30) connected to the pet.

[0005] However, when the user is not talking to others or watching the pet's movements, there are cases where the user is unaware that the pet may move far away, and the pet may stray beyond the user's protection range and bite a nearby person or cause a traffic accident.

[0006] Accordingly, although automatic locking technology has been disclosed to solve such problems, it protects the pet by automatically locking the leash when the pet suddenly runs away and the leash is suddenly pulled out, but there is a problem that the accident prevention effect is reduced because the amount of the pulling shock varies depending on the type of pet dog and the situation, and there are frequent cases where stable locking is not achieved.

[0007] The technical problem to be achieved by the present invention is to provide a leash safety device for a pet traction device that can control the pet's unexpected behavior by setting the leash extension length in various modes with a simple operation of the user.

[0008]

[0009] In addition, the present invention provides a leash safety device for a pet towing device that allows the user to easily set the length of the leash by operating it from the bottom, thereby fundamentally blocking cases of user malfunction due to the operating part formed at the top or cases of operation due to unexpected external force without the user's knowledge due to the user being easily exposed to external force.

[0038] Hereinafter, an embodiment of the present invention having the above-described features will be described in more detail with reference to the attached drawings.

[0039]

[0040] The leash safety device of a pet tow truck according to an embodiment of the present invention comprises a reel portion (110) on which a tow rope is wound, a pole (120) for controlling the rotation of the reel (113), a reel bar (130) that is in close contact with the leash (10) and restricts the rotation of the reel portion (110) by the pole (120) to limit the pull-out length of the leash (10), a pole contact portion (140) that presses the pole (120), and an operating portion (150) that limits the pull-out length of the leash (10) according to the operation of the lifting and sliding, thereby allowing the user to set the pull-out length of the leash (10) with a simple operation.

[0041]

[0042] Hereinafter, with reference to the drawings, the safety device of the lead rope (10) of the pet towing device of the above-described configuration will be described in detail as follows.

[0043]

[0044] First, the reel (110), with reference to FIGS. 2 to 4 and 8 to 10, is configured with a reel (113) on which a pet leash (10) is wound and pulled out or retrieved through a rope hole (112) penetrated through the front end of the case (111) and is rotatably coupled to the front end inner space of the case (111) having a handle (111a) formed at the rear end, a torsion spring (114) coupled to the central region of the reel (113) to elastically retrieve the leash (10), and a plurality of catches (115) arranged at regular intervals on both sides of the reel (113) in a circumferential shape.

[0045] Here, the catch (115) can be formed in an asymmetrical shape so that it does not catch on the catch piece (121) when the reel (113) rotates clockwise (when the lead (10) is pulled in) but catches on the catch piece (121) when the reel (113) rotates counterclockwise (when the lead (10) is pulled out).

[0046]

[0047] Next, the pawl (120), referring to FIGS. 3 to 5 and 9 to 11, is formed to rotate within a certain angle range by being hinged to a first rotation axis (121a) formed on one side of the case (111), and is composed of, for example, a pair of left and right hooking pieces (121) that are fastened or released from a hooking jaw (115) to control the rotation of the reel (113), and a rotating piece (122) that is extended and formed on the upper end of the hooking piece (121).

[0048] Here, the hook piece (121) is formed to protrude and extend toward the hook jaw (115), and a coil spring (133) is coupled to the rear end of the rotary piece (122), so that the hook piece (121) can be elastically separated from the hook jaw (115) by the coil spring (133) with respect to the first rotary axis (121a) so that the rotation of the reel (113) is not restricted.

[0049] Meanwhile, referring to FIG. 4 and FIG. 10, by the push operation of the switch (111b) formed at the top of the case (111), the pressurizing member (121b) formed at the bottom of the switch (111b) presses the rear end (123) of the pole (120), causing the hook (121) to rotate and be forcibly fastened to the hook (115), thereby enabling an emergency blocking of the withdrawal of the lead line (10).

[0050]

[0051] Next, the reel bar (130), referring to FIGS. 4 to 6 and 9 to 11, is configured with a flat-shaped contact piece (131) that is hinged to a second rotation axis (131a) formed at the rear end of the first rotation axis (121a) and is in close contact with a lead line (10) wound around a reel (113), and a pressure piece (132) that is formed opposite to the rotation piece (122) with a coil spring (133) interposed therebetween to elastically press the rotation piece (122).

[0052] Meanwhile, referring to FIGS. 14 and 15, in place of the coil spring (133) in the first and second embodiments, a first coil spring (C1) that presses the pole (120) counterclockwise with respect to the first rotation axis (121a) and a second coil spring (C2) that presses the reel bar (130) clockwise with respect to the second rotation axis (131a) may be independently included.

[0053]

[0054] Here, although not shown, an auxiliary coil spring is further included that is arranged opposite to the coil spring (133) with respect to the first rotation axis (121a) to pressurize the rotary member (122) so that the engaging member (121) can be elastically separated from the engaging step (115), and is configured separately from the coil spring (133), so that even when one coil spring is damaged, the rotary member (122) can be elastically pressed by the remaining coil spring.

[0055]

[0056] Next, the pole contact portion (140), referring to FIG. 5 and FIG. 11, is formed of wing pieces (141) formed on both upper sides of the contact piece (131) and contacting the rear end of the hook piece (121) of the pole (120), so that it can rotate in conjunction with the rotation of the contact piece (131) to allow the hook piece (121) to approach the hooking jaw (115).

[0057]

[0058] Next, the operating unit (150), referring to FIG. 3 and FIG. 9, is configured to adjust the pull-out length of the lead rope (10) in multiple stages according to the user's up-and-down sliding operation, and specifically, is coupled to the other side of the case (111) to slide up and down in multiple stages, and according to the user's up-and-down sliding operation, the pressure piece (132) is pressed so that the reel bar (130) is separated from the pole (120), so that the close piece (131) and the lead rope (10) are mutually separated, and the wing piece (141) is separated from the rear end of the hook piece (121), so that the pull-out length of the lead rope (10) is not limited (free mode), or the close piece (131) is separated from the pressure piece (132) and the coil spring (133) approaches the outermost lead rope (10) that is pulled out through the rope hole (112), and the lead rope (10) is fixed. As the length is released, the wing piece (141) presses the rear end of the hook piece (121) of the pole (120), so that the hook piece (121) is fastened to the hook jaw (115) to limit the pull-out length of the lead line (10).

[0059]

[0060] Here, according to the configuration of the aforementioned pole contact portion (140) and operating portion (150), the first embodiment may be configured with a two-stage mode of a free mode in which the pull-out length of the lead line (10) is unlimited and a safe mode in which the pull-out length is 1.5 m to 3 m, and the second embodiment may be configured with a free mode in which the pull-out length is unlimited, a middle mode in which the pull-out length is 2.5 m to 3 m, and a safe mode in which the pull-out length is 1.5 m to 2.5 m, and the pull-out length is exemplary and may be configured differently depending on the total length of the lead line (10).

[0061] Figures 4 to 7 are for a lead safety device of a pet towing device according to the first embodiment, and specifically, the pole contact part (140) and the operating part (150) are described as follows.

[0062] That is, the wing piece (141) of the pole contact portion (140) is formed to be integrally fixed to both upper sides of the contact piece (131) facing the hook piece (121) and to pressurize the rear end of the hook piece (121).

[0063] In addition, the operating part (150) may be specifically composed of a contact part (151) formed facing the pressurizing part (132) and contacting the rear end of the pressurizing part (132), a fixing part (153) selectively fastened to an operating groove (152) formed in two stages in the inner space of the case (111), and an operating part (154) exposed to both sides of the case (111) and raised and lowered in two stages according to the user's raising and lowering sliding operation.

[0064] For example, when the fixed piece (153) is fixed to the upper groove of the operating groove (152) (see (a) of FIG. 7), the contact piece (151) can pressurize the rear end of the pressure piece (132) to come into close contact with the hook piece (121) or the wing piece (141) that is close to it can retreat to implement a free mode, and when the fixed piece (153) is fixed to the lower groove of the operating groove (152), the contact piece (151) descends and is separated from the rear end of the pressure piece (132), and the close piece (131) is brought into close contact with the outermost lead line (10) by the coil spring (133), and when the lead line (10) is released, the wing piece (141) rotates clockwise to pressurize the rear end of the hook piece (121) so that the hook piece (121) is fastened to the hooking jaw (115), thereby implementing a safe mode.

[0065] Here, referring to FIG. 4, an opposing bulkhead-shaped rail (155) that stably guides the lifting and lowering sliding of the operating member (154) can be formed on the inside of the case (111).

[0066] In addition, the operating section (154) may be formed to be exposed on one or both sides of the case (111), thereby allowing free use of both hands.

[0067]

[0068] Figures 10 to 13 are for a lead safety device of a pet towing device according to the second embodiment, and specifically, the pole contact part (140) and the operating part (150) are described as follows.

[0069] That is, the wing piece (141) of the pole contact portion (140) may be composed of a main body (141a) having a sliding groove formed to slide on the sliding rack (134) formed on both upper sides of the reel bar (130), a wing plate (141b) formed on both sides of the main body (141a) and having upper and lower surfaces with different height differences formed so as to be in stepwise contact with the rear end of the hook piece (121), and an insertion rod (141c) formed on the rear end of the main body (141a) and inserted so as to rotate into the insertion groove (150a) on the front of the operating portion (150).

[0070] Accordingly, the main body (141a) moves up and down the sliding rack (134) according to the lifting and sliding of the operating unit (150), thereby rotating the contact piece (131) clockwise or counterclockwise so that the catch piece (121) can be caught or released from the catch jaw (115).

[0071] In addition, the operating part (150) may be composed of a contact part (151) formed facing the pressurizing part (132) and contacting the rear end of the pressurizing part (132), a fixing part (153) selectively fastened to an operating groove (152) formed in three stages in the inner space of the case (111), and an operating part (154) exposed to both sides of the case (111) and raised and lowered in three stages according to the user's raising and lowering sliding operation.

[0072] Specifically, the operating member (154) is exposed on both sides of the case (111) and, when the fixed member (153) is fixed to the upper groove of the operating groove (152) corresponding to the free mode according to the user's lifting and sliding operation, the contact member (151) presses the rear end of the pressing member (132) so that the wing plate (141b) that is in close contact with or close to the hooking member (121) retracts to allow the release of the lead line (10) (see (a) of FIG. 13), and when the fixed member (153) is fixed to the middle groove of the operating groove (152) corresponding to the middle mode, the main body (141a) is lowered along the sliding rack (134) in conjunction with the guide bar (141c) so that the lower surface of the wing plate (141b) is in close contact with or close to the rear end of the hooking member (121) and, according to the release corresponding to the middle mode of the lead line (10), When the contact piece (131) is rotated at a first rotation angle so that the hook piece (121) is fastened to the hook jaw (115) (see (b) of FIG. 13), and the fixed piece (153) is fixed to the lower groove of the operating groove (152) corresponding to the safe mode, the main body (141a) is lowered along the sliding rack (134) for the second time in conjunction with the guide bar (141c), so that the upper surface of the wing plate (141b) is fastened to or comes close to the rear end of the hook piece (121), and the contact piece (131) is rotated at a second rotation angle according to the release corresponding to the safe mode of the lead line (10), so that the hook piece (121) is fastened to the hook jaw (115) (see (b) of FIG. 13).

[0073]

[0074] Here, referring to FIG. 10, an opposing bulkhead-shaped rail (155) that stably guides the lifting and lowering sliding of the operating member (154) can be formed on the inside of the case (111).

[0075] In addition, the operating section (154) may be formed to be exposed on one or both sides of the case (111), thereby allowing free use of both hands.

[0076]

[0077] Meanwhile, as illustrated in Fig. 11, the groove (150a) formed on the front of the operating part (150) into which the insertion rod (141c) is inserted is formed to be inclined downward and the upper surface is formed with an opening at a certain height, so that the insertion rod (141c) can rotate the wing plate (141b) by going up and down the inclined surface of the groove (150a).

[0078]

[0079] In addition, as shown in an enlarged view in Fig. 11, the upper surface (141b-1) and the lower surface (141b-1) of the wing plate (141b) are formed in a stepped manner or have a streamlined shape to form a height difference, so that the depth of pressure applied to the rear end of the catch piece (121) according to the rotation of the contact piece (131) can be adjusted differently by the lifting and sliding of the wing plate (141b).

[0080]

[0081] In addition, in the first and second embodiments, the operating groove (152) and the fixed piece (153) are formed in a corresponding sawtooth shape to be fastened to each other, and the fixed piece (153) is made of an elastic material to be elastically fastened to the operating groove (152) to enable lifting and sliding.

[0082]

[0083] Meanwhile, although not shown, a rotation detection sensor that detects the rotation of the reel (113) and a control board that controls a speaker that generates a buzzer sound or a vibration motor that generates vibration when the lead (10) is pulled out or stopped corresponding to the pull-out length set by the operating unit (150) by identifying the pull-out length of the lead (10) according to a detection signal from the rotation detection sensor are further included, so that even if the user's gaze is diverted from the pet, the pull-out or stop of the lead (10) can be easily recognized, thereby preventing safety accidents to the pet.

[0084] For example, a display panel (not shown), an LED (not shown), and a speaker are formed in the case (111), and a vibration motor (not shown) is formed in the handle (111a), and the control board can provide the user with withdrawal information by setting the text of the display panel, the light cycle of the LED, the sound effect by the speaker, and the vibration cycle of the vibration motor differently for each step of the withdrawal length, for example, when the withdrawal length is 1 m, 2 m, or 3 m.

[0085] Accordingly, by configuring the leash safety device of the pet tower as described above, the user can easily adjust the pet's range of motion by simply operating the leash pull-out length to be short, long, or free, and perform appropriate leash braking according to the situation. In addition, by preventing the leash from being pulled out more than the set pull-out length, the distance between the pet and the user is maintained at a desired distance, thereby preventing the pet from carelessly falling far away, thereby enhancing safety.

[0086] Figures 16 to 21 illustrate a lead safety device of a pet traction device according to a third embodiment of the present invention, as follows.

[0087] First, the reel (210), with reference to FIGS. 16 and 17, is configured with a reel (211) that is rotatably coupled to the internal space of the front end of the case (10), and on which a pet leash (20) is wound and withdrawn or recovered through a rope hole (11) penetrated through the front end of the case (10), a torsion spring (not shown) coupled to the reel (211) to elastically recover the leash (20), and a plurality of catches (212) arranged at regular intervals in a circumferential shape on both sides of the reel (211).

[0088] Here, the catch (212) can be formed in a symmetrical or asymmetrical shape so that it does not catch on the catch piece (222) when the reel (211) rotates clockwise (when the lead (20) is pulled in) and catches on the catch piece (222) when the reel (211) rotates counterclockwise (when the lead (20) is pulled out).

[0089]

[0090] Next, the pawl (220), referring to FIGS. 17 to 20, is hingedly connected to a first rotation axis (221) formed adjacent to the lower region of the case (10), and is composed of a pair of left and right hooking pieces (222) that are fastened or released from a hooking jaw (212) to control the rotation of the reel (211), and a rotating piece (223) that is extended and formed on the upper end of the hooking piece (222).

[0091] Here, the hook piece (222) can be formed to protrude and extend in a hook shape toward the hook jaw (212).

[0092]

[0093] Next, the reel bar (230), referring to FIGS. 16 to 20, is hinged to a second rotation shaft (231) formed at the lower end of the first rotation shaft (221), and is composed of a contact piece (232) that is in contact with a lead line (20) wound around a reel (211), a pressure piece (234) that is formed opposite to the rotation piece (223) with a first coil spring (233) interposed therebetween and pressurizes the rotation piece (223), and a wing piece (235) that is formed to extend from both ends of the contact piece (232) and contact the rear end of the hook piece (222).

[0094]

[0095] Next, the operating unit (240), referring to FIGS. 17 to 20, is formed at the lower end of the contact piece (232) and coupled to slide back and forth in multiple stages, and according to the operation of the back and forth sliding, the wing plate (242) is separated from the lower end of the hook piece (222) so as not to limit the pull-out length of the lead line (20), or the wing plate is positioned at the lower end of the hook piece so that when a certain length of the lead line (20) is released, the wing plate presses the rear end of the hook piece (222) of the pole (220) so that the hook piece (222) is fastened to the hooking jaw (212) so as to limit the pull-out length of the lead line (20).

[0096] Specifically, a wave-shaped operating groove (232a) is formed on the bottom surface of the contact piece (232) to enable multi-stage forward and backward sliding, and the operating part (240) includes an operating member (241) that allows the user to operate the operating member (241) through an open groove opened at the bottom of the case (10) to slide forward and backward in multi-stages, a wing plate (242) formed on the upper end of the operating member (241) and contacting the rear end of the catch piece (222) on both sides with a height difference, a slide member (243) formed on the upper end of the wing plate (242) and having a slide groove (243a) (see FIG. 6) that guides the forward and backward sliding of the wing member (235), a cylindrical slide member (244) that is inserted into the operating groove (232a), and, as illustrated in FIGS. 3 and 5, a vertical groove formed vertically through the operating member (241) is formed to guide the slide member (244) toward the operating groove (232a). It can be composed of a second coil spring (245) that is elastically pressurized.

[0097] Through this structure, the user manipulates the forward and backward sliding of the operating member (241), so that the first coil spring (233) causes the contact piece (232) to rotate clockwise around the second rotation axis (231) to contact or approach the outermost lead line (20) wound on the reel (211), and as the lead line (20) is released, the wing plate (242) presses the rear end of the hook piece (222), so that the hook piece (221) is fastened to the hook jaw (115), thereby limiting the pull-out length of the lead line (20) to multiple stages.

[0098] Here, as illustrated in Fig. 3, the slide piece (243) of the operating part (240) is coupled to the wing piece (235) at a certain angle (a), and the operating part (241) slides back and forth to adjust the pressure height of the rear end of the hook piece (222) based on the second rotation axis (231), thereby allowing the pull-out length of the lead line (20) to be set in multiple stages.

[0099]

[0100] In addition, the upper and lower surfaces of the wing plate (242) may be formed in steps or curved in a streamlined shape to form a height difference, thereby making the height at which the rear end of the catch piece (222) is pressed different.

[0101]

[0102] Meanwhile, in place of the first coil spring (233), it may be separated into a first separation coil spring that elastically presses the pole (220) in a clockwise direction and a second separation coil spring that elastically presses the reel bar in a clockwise direction.

[0103]

[0104] In addition, the withdrawal of the lead line (20) can be emergency braked through the emergency braking unit (250), and specifically, it can be composed of a switch (252) that rotates by being hinged to a third rotation axis (251) formed in the upper region of the case (10), a fourth rotation axis (253) formed at the rear end of the third rotation axis (251) and rotates, a braking member (254) that is pressed by a pressure member (252a) formed on the lower surface of the switch (252) and rotates to be fastened to a catch (212), and a third coil spring (255) that is in close contact with the braking member (254) and elastically returns the rotation of the braking member (254).

[0105]

[0106] Meanwhile, although not shown, a rotation detection sensor that detects the rotation of the reel (211) and a control board that controls a speaker that generates a buzzer sound or a vibration motor that generates vibration when the lead (20) is pulled out or stopped corresponding to the pull-out length set by the operating unit (240) by identifying the pull-out length of the lead (20) according to a detection signal from the rotation detection sensor are further included, so that even if the user's gaze is diverted from the pet, the pull-out or stop of the lead (20) can be easily recognized, thereby preventing safety accidents to the pet.

[0107] For example, a display panel (not shown), an LED (not shown), and a speaker are formed in the case (10), and a vibration motor (not shown) is formed in the handle (12), and the control board can provide the user with withdrawal information by setting the text of the display panel, the light cycle of the LED, the sound effect by the speaker, and the vibration cycle of the vibration motor differently for each step of the withdrawal length, for example, when the withdrawal length is 1 m, 2 m, or 3 m.

[0108]

[0109] In addition, although not shown, the handle (12) may be configured with a motor of the operating member (241), a string of a closed loop structure connected between the operating member (241) and the reduction gear stage of the motor, and a trigger for controlling the motor, so that the forward and backward sliding of the operating member (241) may be electronically controlled, and the operating member (241) may be fixed to the string and the operating member (241) may slide forward and backward according to the forward and reverse rotation of the string.

[0110]

[0111] Accordingly, by configuring the leash safety device of the pet tower as described above, the user can easily set the leash extension length by operating it from the bottom, thereby fundamentally blocking cases of user malfunction due to the operating part formed at the top or cases of unexpected external force operation without the user's knowledge due to the user's easy exposure to external force, controlling the pet's sudden actions, allowing the user to easily adjust the pet's range of motion by setting the leash extension length in multiple stages with a simple operation, performing appropriate leash braking according to the situation, and preventing the leash from being pulled out more than the set extension length, thereby maintaining the desired distance between the pet and the user, thereby preventing the pet from carelessly falling far away, thereby enhancing safety.
