Definitions

  • the present invention relates to a lifter for repairing a vehicle with the features of preamble part of the independent claim 1.
  • a conventional lifting device for raising an engine is a hanger with a hook that only has the single hanging function.
  • development of the vehicles progresses promptly and trends to obtain a front-wheel drive system attached to the engine in a small-size vehicle.
  • the small-size vehicle is disassembled at a chassis that is conveniently detached from the start. Therefore, the engine can not be repaired by using the conventional hanger to suspend the vehicle.
  • a lifter as shown in Fig. 8 is designed for repairing the vehicle having the front-wheel drive system, to detach the engine, the lifter still has the only lifting efficiency by using a top plate to push the vehicle upward.
  • the two conventional lifting devices respectively have the hook and the top plate all stationary mounted thereon and can not meet all engines in different sizes and various combinations in need of repair. Therefore, workplace has to equip more accessory devices for repairing the engines so that the equipment cost is correspondingly increased and changing the accessory devices is inconvenient to a repairman during repair.
  • the main object of the present invention is to provide a modified lifter to overcome the drawbacks of the conventional lifting devices and to increase repairing and economic efficiency in operation of safety.
  • a lifter for repairing a vehicle comprising the features of the characterizing part of the independent claim 1. In that way a lifter for repairing a vehicle has duplex functions for supporting or hanging operation.
  • a lifter for repairing a vehicle provides a secure locking efficiency to make the lifter safe in operation.
  • a lifter for repairing a vehicle enables to change orientations of a rack on the lifter to support or hang a workpiece mounted on the rack so that the lifter is versatile in industrial utility.
  • a lifter for repairing vehicles in accordance with a preferred embodiment of the present invention comprises a base having a supporting post, an upper arm and a lower arm pivotally attached to the supporting post, a jack pivotally connected to the lower arm, and an L-shaped rack pivotally attached to distal ends of the upper arm and lower arm and having a top plate and a hook mounted on the L-shaped rack.
  • the L-shaped rack adapted to combine a workpiece enables to change orientations to make operation of the lifter versatile.
  • a positioning plate is pivotally attached to a joint of the upper arm and the supporting post and has a channel with multiple detents.
  • the lower arm has a penetrating rod received in the channel to operationally engage with a corresponding one of the multiple dents to provide a locking efficiency to keep the lifter stable in operation.
  • the lifter in the preferred embodiment has a base 1 with multiple wheels 11, 121, a supporting post 2, an upper arm 3 and a lower arm 4 in parallel, a jack 5, an L-shaped rack 6 with a top plate 7 and a hook 8, and a locking device.
  • the base 1 is a substantially ⁇ -shaped structure composed of a long section with two ends, two retractable legs 12 attached to a side of the long section, and a short section extending between the two retractable legs 12.
  • Four wheels 11, 121 are individually attached to the two ends of the long section and two distal ends of the two retractable legs 12 to make the filter move conveniently.
  • the supporting post 2 erects on the base 1 by mounting cross the long section and the short section and has a top end.
  • the upper arm 3 and the lower arm 4 are pivotally attached to the top end of the supporting post 2, wherein each arm 3, 4 is composed of two parallel rods and two transversal rods extending between the two parallel rods. Therefore, the supporting post 2 is clamped between the two parallel rods at one end of each arm 3, 4 by penetrating a pivotal pin 31, 41.
  • the jack 5 is mounted on the base 1 and connects to the lower arm 4 by attaching a penetrating rod 51 to pivotally combine a pushing rod of the jack 5 to a middle section of the lower arm 4, wherein the penetrating rod 51 has a surplus section extending outward at one side of the lower arm 4.
  • the L-shaped rack 6 is composed of two L-shaped frames in pair and multiple transversal extensions formed between the two L-shaped frames.
  • the L-shaped rack 6 has a free section and an engaging section attached to the other ends of the upper arm 3 and the lower arm 4 by inserting two detachable pins 61.
  • the top plate 7 is mounted on an inner side of the free section of the L-shaped rack 6 and the hook 8 is attached to a distal end of the free section. In operation, the top plate 7 adapts to engage with a workpiece that needs to be repaired.
  • the locking device in the lifter of a preferred embodiment of the present invention has a positioning plate 9 pivotally attached to a pivotal joint of the upper arm 3 and the supporting post 2 by the same pivotal pin 31.
  • the positioning plate 9 has a pressing section 92 formed at one end and an inclined saw-shaped hole defined at the other end of the positioning plate 9 to receive the surplus section of the penetrating rod 51 on the jack 5 and the lower arm 4.
  • the saw-shaped hole is composed of a channel 911 and at least one detent 91 communicating with the channel 911 (there are multiple unidirectional detents 91 in the preferred embodiment in the present invention) at an upper edge so that the penetrating rod 51 enables to slide along the channel 911 and to be retained by a corresponding one detent 91 when the L-shaped rack 6 is kept at a stationary position when the L-shaped rack 6 is completely raised.
  • the detent is inclined and unidirectional to keep the penetrating rod 51 from reverse movement.
  • the positioning plate 9 further has at least one cover board 93 (there are two cover boards 93 shown in the preferred embodiment in the present invention) attached beside the positioning plate 9 .
  • Each cover board 93 has a first through hole 931 and a second through hole 932 to allow the pivot pin 41 and the penetrating rod 51 respectively penetrating therethrough so that the positioning board 93 is pivotally attached to the supporting post 2 and the middle section of the lower arm 4 as well.
  • the jack 5 When the lifter operates (with reference to Figs. 3, 4 and 5), the jack 5 is completely retracted to keep the lifter at an unextended station, wherein the L-shaped rack 6 is pulled by the jack 5 via the upper and lower arms 3, 4 to a lowest position (as shown in Fig. 3) and the penetrating rod 5 is retained at a lowest detent 91.
  • the jack 5 extends, the upper arm 3 and the lower arm 4 are pushed upward to lift the L-shaped rack 6 (as shown in Fig. 4). Meanwhile, the penetrating rod 51 slides along inclined faces of the detents 91 one by one and is stopped by the at least one detent until the L-shaped rack 6 is located at a proper position.
  • the penetrating rod 51 is retained by a corresponding one of the detents 91 on the positioning plate 9 to avoid the reverse movement so that a locking efficiency is provided to keep the lifter stable and to prevent collapse even when the releasing lever (button) of the jack 5 is inadvertently actuated.
  • the pressing section 92 is pressed downward to make the opposite end lever up so that the penetrating rod 51 is disengaged from the detent 91 to slide along the channel 911 (as shown in Fig. 5).
  • the jack 5 enables to retract to lower the L-shaped rack 6 to the unextended station.
  • the L-shaped rack 6 can be inverted to correspond to a height of the workpiece by simply withdrawing the pins 61. After the L-shaped rack 6 is inverted, the pins 61 are inserted again to keep the L-shaped rack 6 in position on the upper arm 3 and the lower arm 4 so that the workpiece is conveniently switched between a supporting state and a suspending state.
