Description

  The present invention relates to a fixed reel-type pet telescopic lead for holding a pet when the pet is allowed to play freely in a wide place such as a garden in a building, an outdoor garden, or a parking lot.

When taking a pet for a walk, there is a reel-type lead that can freely adjust the winding length of the lead with a reel as a lead connecting pets. Many of the reel-type leads can be set in two states: a fixed state in which the lead is fixed in an appropriate length state, and a free state in which the lead is freely drawn out. In the free state, a force that is automatically wound by the mainspring is generated to prevent the lead from loosening. However, in the case where pets are connected in a wide place such as a garden inside and outside a building, there is no function that can freely adjust the length of the lead as described above. In addition, when a pet suddenly starts running, no function is added to prevent the lead from extending.
Patent Publication No. 2006-14649

  As mentioned above, when using a conventional lead for fixation, the length of the lead is limited. Therefore, when the pet walks inside the lead shorter than the lead length, the lead is slackened. Or in contact with the ground in a large area such as a garden or parking lot outside the building, rubbing into the ground to collect rainwater, generating dust, or damaging the lawn, etc. Become.

  In addition, the conventional fixed lead can run freely if the pet suddenly starts to run (for example, when it jumps on a person), and the lead can be extended freely. Not to prevent. In such a case, if the lead is made of metal, there is a risk of damage to a counterpart (for example, the body of an automobile such as a parking lot).

In order to solve the above-described problems, the present invention has the following configuration.
The lead for connecting the pet is a fixed reel-type pet expansion / contraction lead capable of winding the lead by an elastic body such as a spring built in the reel.

  Therefore, since the lead connecting the pet can be automatically pulled out or wound up according to the position where the pet walks, the lead is always pulled with a moderate load while the pet is walking. This is a fixed reel-type pet expansion / contraction lead that does not loosen.

  In the locking reel type pet telescopic lead, the locking mechanism has a locking mechanism that can stop the movement of the reel against a sudden movement of the pet and then automatically releases the stopping when the pet stops. This is a reel-type telescopic lead for pets.

  In the fixed reel-type pet telescopic lead, the main body and the support column for fixing the main body are inserted into the shaft of the main body, and there is a certain gap between the shaft and the support column. This is a fixed reel-type pet expansion / contraction lead that can be easily rotated when the main body is pulled out suddenly.

  In order to fulfill the above-mentioned fixed reel-type pet stretchable lead, the lead used for it is easy to wind around the reel, and it uses round and flat cords with excellent strength, heat resistance and water resistance. To do.

  As described above, according to the present invention, in the fixed reel type pet telescopic lead, the lead can be automatically pulled out or taken up according to the walking position of the pet. Does not sag, so it will not hurt the floor inside the building where pets are connected, and in large areas such as outdoor gardens and parking lots, it will come into contact with the ground and dents will form on the ground. It is possible to eliminate causes such as accumulation of dust, generation of dust, and damage to the lawn.

  Also, when the connected pet suddenly surprises something or tries to jump to an infant etc., the reel lock mechanism around which the lead is wound operates and the lead is pulled out. Can be stopped. Thereafter, when the pet is stationary, the lock mechanism is released, and the lead can be freely pulled out or taken up again.

  In the fixed-reel-type pet telescopic lead, there are appropriate gaps between the column supporting the body and the shaft of the body, between the shaft and the casing, and between the casing and the reel. The main body and the lead can freely rotate.

  The lead connecting pets is easy to wind around the reel, has excellent strength, heat resistance and water resistance, and uses a round and flat string of material to make the reel move smoothly and to fix the reel. The life of the PET stretchable lead can be extended.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  FIG. 1 is a plan view partially illustrating a description of a fixed reel-type pet telescopic lead 50 according to an embodiment of the present invention. FIG. 2 shows a front view of FIG. FIG. 3 shows an example of a system in which the fixing shaft of FIG. 2 is driven into the ground, while an example of a system in which a suction cup 13 is attached to the end of the fixed shaft for a building. FIG. 4 shows a simplified AA cross-sectional view in FIG. FIGS. 5 to 8 show examples in which sliding protrusions 26 are provided on the upper and lower portions of the casing 1 of the fixed reel-type pet telescopic lead 50.

  As shown in FIGS. 1 and 4, the fixed reel-type pet expansion / contraction lead 50 is connected to the reel 16 of the casing 1, and the leading end of the string-like lead 2 connected to a pet collar or the like is connected to the tip. The lead 2 is wound around a reel 16 and incorporated therein. The reel 16 has a reel shaft 22 integrated with the reel 16 with a claw on the inner peripheral portion of the mainspring 14 and a claw on the outer peripheral portion of the mainspring 14 fixed on the casing 1. The obtained lead 2 is wound. As a result, the casing 1 contains a lead 21 wound around the reel 16 several times.

  Further, since the lead 2 is connected to the collar of the pet at the tip, when the lead 2 having a necessary length is pulled out when the pet walks, the reel 16 and the reel shaft 22 are integrated. The mainspring 14 is wound, and the winding force is acted on the lead 2. Thereafter, when the pet approaches the fixed reel-type pet telescopic lead 50, the lead 2 is wound up. In this way, the lead 2 can always be wound up or pulled out as the pet walks.

  Here, when the lead 2 is pulled out from the reel 16, a load corresponding to the winding force is always applied to the pet. Therefore, if the winding force is very large, a load is applied to the neck of the pet and the pet feels uncomfortable. Therefore, the winding force of the reel 16 is preferably 5N to 100N although it depends on the size of the pet.

  As shown in FIG. 1, a reel side plate 18, a weight 6, a claw 7, and a torsion coil spring 8 are built in both side surfaces of the reel 16 of the fixed reel type pet expansion / contraction lead 50. A saw-shaped rack 5 as shown in FIG. 1 is processed on the outer periphery. As shown in FIG. 4, the weight 6, the claw 7 and the torsion coil spring 8 are supported by the casing 1 by a support shaft 15. Further, the spring tip 23 of the torsion coil spring 8 shown in FIG. 1 is hooked to the side wall of the casing 1 and the spring rear end 24 is hooked to the claw 7. When a pet is running slowly or walking at a constant speed, the state shown by the broken line in FIG. 1 is maintained.

  However, when the pet suddenly starts running, the lead 2 connected to the collar of the pet is pulled and the reel 16 tries to rotate. However, the reel 16 is connected to the inner peripheral end of the mainspring 14. Since the outer peripheral end of the mainspring 14 is connected to the casing 1, the rotational force to rotate the mainspring 14 is caused by rotation of the fixing reel-type pet telescopic lead 50 around the fixing support 3. Since it is set to be larger than the force, when the lead 2 is pulled by the pet, the fixed reel type pet telescopic lead 50 is rotated first. When the fixed reel-type pet telescopic lead 50 rotates, centrifugal force is generated in the weight 6, the weight 6 moves to the wall side of the casing 1, and the claw 7 integrated with the weight 6 moves to the center side of the casing 1. By doing so, the claw 7 is engaged with the rack 5 of the reel side plate 18, and the casing 1 and the reel 16 are integrated to restrain the pet.

  The fixed reel-type pet telescopic lead 50 operates after the pet is stationary until the pet's pulling force is stopped, and when the pet's pulling force is released, the pawl 7 biting into the rack 5 is twisted. It is returned by the coil spring 8 and enters a free state.

  As described above, in order for the locking mechanism to operate, the fixed reel type pet telescopic lead 50 must be freely rotated. For this purpose, the gap 11 between the upper presser plate 9 and the lower presser plate 10 supporting the fixed reel-type pet expansion / contraction lead 50 is set to 0.1 to 1.0 mm, and the fixing column supporting the casing 1 is used. 3 and the fixing support insertion hole 25 of the casing 1 are required to have a clearance of 0.1 to 1.0 mm. Further, it is necessary to provide a clearance of 0.1 to 1.0 mm between the casing 1 and the reel shaft 22. Further, it is preferable that the casing 1 as shown in FIG. 5 to 8 show examples of preferable protrusions. In addition, the figure shown by FIGS. 1-4 is an example without a processus | protrusion.

  As can be seen from the above explanation, the best type of the lead 2 used in the present invention is strong in strength with a round or flat string made of fibers in order to maximize the function. It is necessary to select a material with excellent heat and water resistance. For example, nylon fiber, polypropylene fiber, and aramid fiber are preferable.

  INDUSTRIAL APPLICABILITY The present invention can be used in an industrial field where a lead is manufactured and sold for fixing a pet outdoors in a building or a garden.
