Description

{APPARATUS FOR GUIDING PET LEAD}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pull rod guide device for a pet, and more particularly to a pull rod guide device for a pet which is detachably attached to a user's strap and realizes a convenient walk between the pet and the user.

Generally, a pet tow line corresponds to a rope or string having a certain length, which is detachably connected to the neck of a pet.

The collar and the tow line are used to take a walk and exercise while the pet is under the constant control of the user outdoors and can prevent the pet from accidentally leaving the user even if it does not cause damage to the user or the people around the pet. It is also used as a means.

Since the movement of the pet is performed in the region within the circular radius of the traction line with the center of rotation of the user's hand, the pet can only operate in a region within a relatively narrow arc radius.

Here, since the pet is pulled out of the region of the arc radius and tensile force is generated on the pull string and the neck collar to pull the neck of the pet, the pet is very stressed, and when walking or exercising outside, There is a problem that causes the action to occur.

In addition, when the pet and the user take a walk outside, the pet moves on the left side from the right side of the front of the user depending on the outdoor environment, so that the tow line extended from the pet's neck collar interferes with the user's movement There is a problem.

Since the patent document 1 or the patent document 2, which is the background of the invention, discloses only a general pull string or a neck string, the pets can be stressed due to the tension transmitted through the pull string and the neck string, It can act as a disturbing factor to the movement as it inhibits the movement of the user.

The lower case 210 is manufactured to be disassembled or assembled into an upper side and a lower side so as to improve assembly and fabrication. The lower case 210 is formed in a cylindrical shape.

In the lower case 210, a passage hole 211 for fitting the rail bar 120 of the guide rail is formed.

Here, the passage hole 211 is formed to penetrate between one side surface and the other side surface of the lower case 210, and has a hole size relatively larger than the diameter of the rail bar 120.

In the lower case 210, a coupling space of the driving wheel 250 and the guide wheel 260, a wheel bearing installation space, a motor shaft passing space, and various wire passing spaces are formed.

The upper case 220 is a box-shaped case closed inside with a side wall and a ceiling except for an opened bottom, and is coupled to an upper portion of the lower case 210. [

Here, the open bottom edge of the upper case 220 is in contact with the upper portion of the lower case 210, and can be fixed by a plurality of fastening bolts.

The upper case 220 includes a mode selection switch 202 for selecting an automatic mode or a manual mode for selecting a movement pattern of the movement module 200 and a power switch for turning on / (203) are displayed.

The guide wheel 260 supports the rail bar 120 on the opposite side of the driving wheel 250 so that the moving module 200 can move along the rail bar 120 by the rotational force of the driving wheel 250 .

Hereinafter, an operation method of a pull rod guide device for a pet according to an embodiment of the present invention will be described.

3 to 5 are plan views for explaining a method of operating the pull rod guide device for a pet shown in FIG.

Referring to Figs. 3 to 4 together with Fig. 2, the user presses the power switch 203 to boot or activate the control unit 201. Fig.

Accordingly, the control unit 201 checks the measured value in accordance with the bending deformation of the angle sensor unit 300, after being made ready for operation corresponding to the operation algorithm previously recorded in its memory.

For example, when the pet P moves from the state of FIG. 3 to the state of FIG. 4, the pull string 400 is arranged to be inclined at the front position of the user who is fastening the strap 1.

The obliquely disposed towline 400 may interfere with the movement of the user who is taking a walk together with the pet P as a movement obstruction factor.

As the pet P continues to move to the left front side, the angle sensor unit 300 is deformed to the left due to the tensile force applied to the inclinedly disposed tow line 400, and the measured value Is inputted to the control unit 201 side.

5, the control unit 201 controls the rotation angle of the motor 240 so as to prevent the inclined pull string 400 from covering the front of the user, as shown in FIG. 5, 241).

In this case, the driving wheel 250 rotates in accordance with the rotation of the motor rotation shaft 241, so that the moving module 200 moves from the state of FIG. 4 to the state of FIG. 5, As shown in FIG.

Referring to FIG. 5, the pull string 400, which is held in a one-letter form between the moving module 200 and the pet P, does not hinder the movement of the user walking with the pet P, In addition, the pull string 400 of the pet P and the user can be prevented from interfering with each other. As a result, a companion walk without inconvenience can be made possible between the pet P and the user.

When the moving module 200 moves to the position shown in FIG. 5, the pull string 400 becomes a one-character form. In this case, since the angle sensor unit 300 is restored to its original state, the control unit 201 stops the rotation of the motor rotation shaft 241 of the motor 240 based on the restoration time.

Here, although not shown in detail, the motor 240 may be a device having an electromagnet type brake means built in to prevent the motor rotation shaft 241 from moving when the motor rotation shaft 241 stops rotating.

The motor 240 is configured such that the brake means can be locked or released corresponding to a value set in a predetermined condition or algorithm corresponding to a signal from the mode selection switch 202. [

That is, when the user presses the mode selection switch 202 once, the mode is switched to the automatic mode, and if it is pressed again, the mode can be switched to the manual mode.

The automatic mode refers to an operating state in which the moving module 200 is operated corresponding to the measured value of the angle sensor unit 300 and the manual mode refers to a state in which the brake unit of the motor 240 is released, Means an operating state in which the motor rotating shaft 241 can be driven to rotate passively by an external force irrespective of the measured value of the angle sensor unit 300.

That is, the manual mode is an operation in which the moving module 200 is driven by the rail bar 120 of the guide rail 100 in a passive manner along the extending direction of the rail bar 120 corresponding to the pulling and pulling of the pet P, State. ≪ / RTI >

The present embodiment can change the connecting point of the pull string 400 by the moving module 200 as the pet P moves in the automatic mode or the manual mode. Accordingly, the action area of the pet P is increased, and movement and walking can be relatively freely performed.

In addition, since the moving module 200 is also moved when the pet P repeatedly moves back and forth, the tension may not be excessively generated in the pull string 400, Can be less stress transmitted through the pulling cord and the collar, so that the frequency of stress can be reduced and it can also contribute to the health improvement of the pet (P).

6, a guide rail 100 according to an embodiment of the present invention includes a ring-shaped coupling part 110 fitted to the strap 1, a support part 110 extending in the upward and downward directions from the bottom of the front surface of the coupling part 110, And two rail bars 121 and 122 each having a circular cross section bent to face each other after being protruded from the front surface of the fastening part 110.

The guide rail 100 includes an intermediate rail bar 124 having a circular cross section and fastened to a threaded portion or a screw hole 123 of the rail bars 121 and 122 on both sides.

Here, the intermediate rail bar 124 is configured to be mountable in a threaded manner between the rail bars 121 and 122 on both sides, and has the same diameter as the intermediate rail bar 124. However, the intermediate rail bar 124 may have different lengths (for example, Bar set. ≪ / RTI >

That is, the user selects one of the intermediate rail bar sets corresponding to his or her body size or the size of the strap 1 and then separates the selected intermediate rail bar 124 between the rail bars 121, The entire length of the guide rail 100 can be adjusted to the user's body size.

In addition, the pull string 400 according to the application example can be connected to the neck line 2 of the pet via the winding module 600. [ Here, the winding module 600 may be a device for unwinding and supplying the pulling string 400 by the tension applied by the pulling string 400, or winding the pulling string 400 by using elastic force when the tension is removed have.

The above-mentioned handle ring part 500 is connected to the pulling line 400 or the winding module 600, and is used for forcing the user to restrict the behavior of the pet or to pull the user in a desired direction. It can be an additional means that the user can grasp and use.
