Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an elevating / lowering tool for vehicle tires that can easily elevate and lower the tires, for example, when mounting a chain on the vehicle tires.

[0002]

[Prior art and its problems]

 Conventionally, when the road is covered with snow, chains are attached to the tires to prevent slip accidents due to snow. By the way, when installing this chain, contact the jack with the chassis of the vehicle, lift the vehicle with this jack and install the tire while the tire is slightly above the ground, or move the vehicle back and forth. However, methods such as attaching chains are being used. In the former case, the tire is raised while the jack is set on the chassis of the vehicle and operated, so not only is the setting of the jack cumbersome, but the operation is also cumbersome. Also, in the latter case, it is often experienced that the work is more troublesome than in the case of using a jack because the chain is mounted while moving the vehicle.

The present invention was developed in view of the above situation, and can be easily attached to a vehicle tire when a chain is attached, and the tire can be easily floated by only slightly moving the vehicle. It is an object of the present invention to provide an elevating / lowering tool for vehicle tires which can be manufactured, is extremely easy to operate, is safe, and can be mass-produced at low cost.

[0004]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention is a vehicle tire elevator including a mounting member to be mounted on a vehicle tire fixture, which is provided on a side closer to an end of an elevator holder having an appropriate length. The mounting member is preferably a box wrench, and a single or a plurality of box wrenches are provided, and each wrench is fixed to the elevating and lowering body so as to be movable and adjustable, and a mark confirmation portion is provided at one end of the elevating and lowering body. It is preferably provided. The other end of the lifting / lowering holder is preferably provided so as to project from the outer periphery of the tire.

[0005]

[Action]

 A method of using the lifting device according to the present invention will be described. First, of the vehicle tires, a mounting member (box wrench) provided near the end of the lift holder is attached to the fastener (nut) of the tire to be floated, and the other end of the lift holder is attached to the tire. Set it so that it projects to the outer circumference of. Then, when the car is slightly moved in one direction, the car is stopped when the lifting / lowering holder is also positioned vertically to the ground surface due to the fine rotation of the tire. Then, the projecting lower part of the other end of the lifting / lowering holder is securely erected on the ground, and the tire is kept in a floating state.

With the tire floating, it is possible to perform work such as mounting a chain. Next, to return the tire to its original state, slightly move the tire in the opposite direction to separate the lift holder from the ground, and the tire comes into contact with the ground, so it was rotated in an inclined state. By removing the lifting holder as it is from the tire, it is possible to easily lift and lower the tire.

【Example】

 Embodiments of the vehicle tire lifting device according to the present invention will be described below with reference to the drawings. In FIGS. 1 and 2, reference numeral 1 denotes an elevating and lowering holder having an appropriate length, which is made of metal, synthetic resin having a strength capable of withstanding the weight of a vehicle, or other material. Use material. Further, the length of the lifting / lowering holder 1 is such that the other end of the lifting / lowering holder 1 protrudes from the outer periphery of the tire and floats when the tire is mounted on a vehicle tire. The length shall be designed arbitrarily according to the implementation. Reference numeral 2 denotes a plurality of mounting holes formed on the side closer to one end of the lifting / lowering holder 1, and a mounting rod 5 of a mounting member 4 provided with a box wrench 3 at one end is fitted into the mounting hole 2, A nut 6 is screwed onto the end of the mounting rod 5.

Reference numeral 7 denotes a projecting portion provided on the other end of the elevating / lowering body 1. In addition to this example, a flat support plate 8 may be provided on the projecting portion 7. Further, a mark confirmation portion (vertical pole or the like) 9 is provided at one end of the lift holder 1 so that the driver can check the vertical state of the lift holder 1 from the driver's seat. Reference numeral 10 is a support rod that is inserted into and supported by the hole of the cap wheel 12 of the tire 11, and 13 is a driver portion formed at one end of the lift holder 1 for removing the cap wheel 12.

FIGS. 4 to 7 show other examples of the lift holder 1, and FIG. 4 shows an example in which four box wrenches 3 are provided at one end of the lift holder 1. FIG. 5 shows an example in which the box wrench 3a is screwed to the bolt portion 14 provided at one end of the ascent / descent holder 1. In FIG. 6, a nut portion 15 that rotates about 90 degrees around one end of the lifting / lowering holder 1 is provided, and the nut of the tire 11 is removed and screwed to a bolt of the tire. Is an example in which is fitted to the nut of the tire 11. FIG. 7 shows an example in which a locking ball 16 is provided inside the box wrench 3 of the mounting member 4 and is locked to the tapered surface 11b of the nut 11a of the tire 11 to ensure the mounted state.

In FIG. 12, a plurality of locking pins 19 are provided inside the box wrench 3 of the mounting member 4, and the locking pins 19 are locked in the recesses 11c formed in the nut 11a at the time of mounting, This is an example in which the stability of is designed. 10 and 11 show an example in which the lifting holder 1 is attached to the vehicle 17, and in this case, a supporting member 18 pivotally mounted at an appropriate position on the chassis of the vehicle 17 The support member 18 is erected so that the tire 11 of the vehicle 17 can be floated in a stable state. 8 and 9 show an example in which the vehicle 17 is lifted and lowered only by the support member 18 described above without providing the lift holder 1.

Next, the operation of the above embodiment will be described. First, as shown in FIG. 2, the box wrench 3 is inserted into the nut 11a of the vehicle tire 11 and moved up and down to the position shown by the solid line in FIG. 3 (or in an inclined state such that the up-and-down holding body 1 comes into contact with the ground). The holding body 1 is mounted and set so that the other end of the lifting / lowering holding body 1 projects on the outer periphery of the tire 11. Next, when the vehicle is moved to rotate the tire 11 in the direction indicated by the arrow in FIG. 3 by about 45 degrees, the lifting / lowering holder 1 rotates as shown by the chain line with the rotation of the tire 11 to reach the ground. On the other hand, when the vehicle is stopped while the vertical state is maintained and the projecting portion 7 stands on the ground, the projecting portion 7 abuts the ground vertically and the tire 11 is lifted. Be sure to maintain.

In this state, for example, a chain or the like can be mounted, and in this case, another tire can be locked by a stopper or the like, or can be held by a support member 18 as shown in FIG. Alternatively, a proper support may be interposed between the chassis and the ground. Next, when lowering the tire to set it in the original state, if the vehicle is slightly moved in the opposite direction to the above, the lifting holder 1 is released from the upright state due to the reverse rotation of the tire. By removing the mounting member 4 of the lifting / lowering holder 1 from the nut 11a of the tire 11 as it is, the lifting / lowering work of the tire can be easily performed.

[0013]

[Effect of the device]

 As is clear from the above, the present invention has the following excellent effects. That is, the lifting device can be easily attached to and detached from the vehicle tire, and its handling can be performed extremely easily as compared with the conventional jack operation and the like, and the operability is not limited, and the safety is improved. It is also excellent in that it has an effect that it can be manufactured at low cost because of its simple structure.
