[Problems to be solved by the device]

 However, in the case of using the jack used for removing the wheels of the automobile, the rack supporting the jack travels on the pinion gear on the traveling platform as described in JP-A-1-98598. However, there is a limit to the range in which the rack can travel, and it takes a lot of time to move beyond the range. Further, as described in Japanese Patent Laid-Open No. 5-116893, a vehicle body is moved by a receiving roller 33 mounted on a support base 31 on a jack portion 32 for supporting the vehicle body of an automobile. It had a drawback that it was easily scratched, and the car body was disengaged from the receiving roller 33, causing troubles such as accidents. Further, as described in Japanese Utility Model Laid-Open No. 63-128164, when a spare tire is attached to the jack mounted on the vehicle body and the spare tire is moved up and down to laterally move the vehicle, it is unnecessary for normal running. There was a drawback that it was necessary to attach such spare tires to the vehicle body.

Furthermore, when there is not enough space for the jack to be inserted between the ground and the vehicle body due to being caught in mud or the like, it is necessary to dig the ground to obtain a space into which the jack can be inserted. Yes, it was very troublesome.

Therefore, in order to solve the above-mentioned problems, the jack of the present invention, which is used for removing the wheels of the vehicle, has no limit to the range in which the vehicle can be moved, and the body is scratched, or the receiving roller or the like is damaged. There will be no troubles such as accidents due to the car body coming off, and it can be used even if there is not enough clearance between the car body and the ground. It is designed to provide a jack that is used when a vehicle is derailed without having to leave it.

[Embodiment of the invention]

 An embodiment of a jack used when the vehicle of the present invention is demounted will be described below with reference to the drawings.

In FIG. 1, reference numeral 1 denotes a support base for supporting a vehicle body of an automobile, in which an elastic packing 3 is affixed on a metal frame 2 so as to securely contact and hold the vehicle body of the automobile. Reference numeral 4 denotes a traveling base made of a metal frame, which is provided with traveling wheels 6 formed of a caterpillar-shaped endless track wound between a pair of rotating rollers 5 arranged at a predetermined interval. A tension adjusting roller 7 is rotatably attached to an upper position of the traveling wheel 6 of the traveling platform 4.

Further, a pantograph-type jack portion 8 is attached between the support base 1 and the traveling base 4, and the jack portion 8 can extend and contract between the support base 1 and the traveling base 4. It is connected. A pair of guide holes 9 extending along the lengthwise direction are provided on the upper surface of the traveling platform 4, and a pair of stoppers 10 oriented at right angles to the longitudinal direction of the traveling platform 4 are provided in the guide holes 9. , Each is movably attached. Reference numeral 11 is a spring for urging the stopper 10 toward the inside of the traveling table 4, and 12 is a bolt for positioning the stopper 10.

By extending the jack portion 8, the support base 1 can be lifted high.

In this example, the jack portion 8 can be easily attached to and removed from the traveling base 4, so that a commercially available jack can be attached to the traveling base 4 as the jack portion 8 at a very low cost. Now you can get a jack to use when you leave your car. Further, the jack portion 8 can be removed from the traveling base to be compact and stored in the trunk of the vehicle body or the like.

FIGS. 2 and 3 show a second embodiment of a jack used when the vehicle of the present invention is to be removed from a wheel. The jack 8 is fitted into the opening on the upper surface of the traveling base 4 and then the traveling base 4 is inserted. The jack portion 8 and the traveling base 4 are integrated by fixing with a retaining pin 13 provided in an opening on the upper surface.

FIG. 4 shows a third embodiment of the jack used when the vehicle of the present invention is demounted. That is, after attaching the tension adjusting roller 7 to the bearing portion 14 of the jack portion 8 and fitting the bearing portion 14 into the opening portion on the upper surface of the traveling platform 4, a pair of protruding and retracting members provided in the opening portion on the upper surface of the traveling platform 4 are installed. It is designed so that it can be prevented from coming off by the free coming-off metal fitting 15.

The pair of retaining fittings 15 are respectively supported by springs 16 attached to opposing inner walls in the opening on the upper surface of the traveling table 4. Therefore, by fitting the bearing portion 14 of the jack portion 8 into the opening of the upper surface of the traveling table 4 through the pair of retaining metal fittings 15, the pair of retaining metal fittings 15 is automatically elasticized by the spring 16 thereafter. Since it is projected into the recess 17 on the upper surface, the bearing portion 14 can be securely prevented from coming off. At this time, it is also desirable that the retaining metal 15 can be fixed to the recess 17 on the upper surface of the bearing portion 14 with a screw or the like.

FIG. 5 shows a fourth embodiment of the jack used when the vehicle of the present invention is demounted. That is, the jack portion 18 provided with a cylinder 19 for hydraulic or pneumatic pressure is attached to the upper surface of the traveling base 4, and the support base 1 is mounted on the jack portion 18.

Reference numeral 20 denotes a traveling rail 20 made of a metal plate such as stainless steel or aluminum, and the traveling wheels 6 of the traveling platform 4 are preferably mounted on the traveling rail 20 laid in a side groove or the like for use. . The traveling rail 20 has rising portions 21 formed at both end portions thereof, and a traveling surface 22 is provided with uneven cleats 23. The traveling rail 20 can be expanded and contracted by connecting a plurality of slidable rails.

When using the jack used for removing the wheels of the vehicle of the present invention, when the tire is removed from the side groove or the like, the traveling rail 20 is laid in the side groove to remove the vehicle of the present invention. Set the jack used for wheeling on the traveling rail 20 in the side groove. Then, the jack 8 is extended to mount the support base 1 under the vehicle body of the automobile, and the jack 8 is further extended to float the automobile body, and the traveling wheel 4 is a track-shaped endless track. 6 may be rotated. To drive the traveling wheels 6, although not shown, electric motors and the like are attached to the traveling platform 4 so that the traveling wheels 6 can be driven or a towing vehicle can be used. is there.

By doing so, the vehicle body of the automobile can be easily moved in the direction of coming out of the side groove, and since it is stable, the moving operation can be performed easily and quickly without difficulty.

In the above-mentioned embodiment, the track 6 is a caterpillar-shaped endless track, but it is needless to say that a rubber crawler belt or the like may be used. Further, the shape of the rotating roller 5 may be such that it meshes with the running wheel 6 formed of a caterpillar-shaped endless track, or may have a structure in which dirt or the like is unlikely to adhere.

FIG. 6 shows a fifth embodiment of the jack used when the vehicle of the present invention is demounted.

That is, the traveling wheels 6 are attached to the four corners of the base 24 of the jack portion 8, while the traveling rail 20 has a pair of inward concave section cross-sections 25 on which the traveling wheels are fitted and serve as tracks. It has a C shape. In the figure, (a) shows a state in which the jack portion 8 and the traveling rail 20 are separated, and (b) shows a state in which the jack portion 8 is inserted in the traveling rail 20 as seen from the longitudinal direction of the traveling rail 20. The case is shown. Further, the jack portion 8 can freely move on the traveling rail 20 regardless of the raised position of the support base 1.

FIG. 7 shows a sixth embodiment of the jack used when the vehicle of the present invention is demounted.

In contrast to the fifth embodiment, the traveling rail has the inward concave section 25, whereas the present embodiment has a pair of outward concave section 25. The base 24 of the jack portion 8 has a straddle shape, and traveling wheels 6 are attached to the four corners of the base 24. Therefore, the base 24 of the jack portion 8 is assembled so as to straddle the traveling rail 20. As in the above-described embodiment, the jack portion 8 can freely move on the traveling rail regardless of the height of the support base 1.

FIG. 8 shows a seventh embodiment of the jack used when the vehicle of the present invention is demounted, which is a modification of the fifth embodiment.

That is, the entire jack portion 8 is configured to be completely housed inside the traveling rail 20 having the pair of recessed cross sections 25 that face inward.

First, the traveling wheels 6 are arranged at both ends of the base 24, and the support base 1 is provided so as to connect the connecting members 27 extended from each of the pair of bases 24. The base 24 is connected by a bolt rod 27. A ring portion 28 for mounting a handle for rotating the bolt rod is provided at one end of the bolt rod 27.

In the jack constructed as described above, the uppermost surface of the supporting table 1 is the same as or lower than the uppermost surface of the traveling rail 20 when the supporting table 1 is at the lowest position. Since the width of the support base 1 is smaller than the opening width of the traveling rail 20, the jack 8 can freely move inside the traveling rail 20 without the supporting base interfering with the traveling rail 20.

The use of this jack is extremely effective when there is a very small gap between the vehicle body of the automobile and the road surface. Specifically, the jack 8 may or may not be inserted into the traveling rail 20 in advance before use, but first, the traveling rail 20 is secured with a clearance for insertion. Insert the rail between the car body and the road surface. Since the height of the traveling rail 20 is extremely low as compared with, for example, the above-described embodiment, it is easy even if an action such as digging a road surface to secure a gap is required. If the jack portion 8 is not inserted into the traveling rail 20 and is inserted and the bolt rod 27 is rotated by a handle or the like, the bases 24 are attracted to each other and the support base 1 is raised to raise the vehicle body. Can be raised. Then, in that state, the jack portion 8 may be freely moved on the traveling rail 20.

The travel range of the jack portion 8 can be increased by making the traveling rail 20 extendable and / or connectable.

Since this embodiment is configured as described above, even if the gap between the vehicle body and the road surface is small, it is possible to move the vehicle body in a floating state without difficulty, and even the jack body is very compact. Can provide a jack.

In all of the above embodiments, when the support base 1 is mounted on the jack 8 so as to be rotatable in a rotary table manner, the moving direction of the vehicle body deviates from the moving direction of the traveling wheels 6. It is very convenient and secure.

Further, as the structure of the support base 1, the upper surface, that is, the contact portion with the vehicle body, is made of an elastic body such as rubber or the like in order to prevent damage to parts of the lower body of the automobile. Various cushioning materials such as metal or springs such as air can be selected.

Further, the extension and contraction of the jack portion 8 may be performed by using an ordinary manual handle, but it may be automatically performed by attaching an electric motor or the like. Needless to say, the jack type is not limited to the pantograph type, and any mechanism other than the cylinder type may be used as long as it can move the support base 1 up and down. Further, hydraulic jacks, air jacks, etc. can be used above and below the support base 1 instead of screw type jacks for rotating bolt rods.

[Effect of the invention]

 The jack used when the vehicle of this invention is to be unloaded can be folded and stored in a trunk when it is not in use, and taken out and used when the tire is unlucky in the side groove. It is possible to quickly eliminate wheel derailment.

That is, when the tire is derailed to the side groove or the like, the jack used for demounting the vehicle of the present invention is set in the side groove, and the jack portion is extended and supported under the vehicle body of the vehicle. With the pedestal attached and the jacks extended further to float the car body, the running wheels, which consist of a caterpillar-shaped endless track, can be rotated.

By doing so, the vehicle body of the automobile can be moved in the direction of slipping out of the gutter without being restricted by the size of the equipment, and the running wheels can be moved even if there are stones or irregularities on the ground. Since it does not get caught, it can be used regardless of the road surface condition. And because of this stability, the moving operation can be performed easily and quickly without any difficulty.
