Description

Regular lift lift {LIFT FOR REPAIRING VEHICLE}

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a vehicle fixed cost lift in which vehicle supports such as plates and beams are stored in a pit provided on the floor when lift down.

In the conventional fixed-cost lift, a pit is provided on the bottom surface to improve work efficiency, and the vehicle support can be accommodated in the pit so that the bottom surface is lifted up or down. Considering removing the irregularities as much as possible is considered.

As this structure, the technique of Unexamined-Japanese-Patent No. 1-7596 is known, for example. This is to install the pit cover which can be opened and closed manually by the pit, close the pit by the pit cover at the time of lift-up or lift-down, and make the top of the pit at the same level as the surrounding bottom surface. By utilizing the synergy of the pit cover, the pit cover is opened without using a hand.

However, the manual opening and closing operation of the lift cover as described above may work while the operation is cumbersome to open, and the cover for flattening has not sufficiently exhibited its effect, and the cover can be closed in the case of lift up. Since the cover is provided with an opening through which a cylinder or the like for moving up and down is fitted, a cover for closing the opening in addition to the pit cover is required to completely close the pit at the time of lift down.

Moreover, in order to reduce the operation of the opening and closing operation of the lift cover, it is conceivable to perform the operation of the lift cover by using power, but the mechanism is also complicated, and the pit must be deep as much as the power is installed. As a result, a problem arises that garbage and water easily accumulate in the pit again, and cleaning and draining are difficult.

Then, the subject of this invention is providing the fixed cost lift which always makes a pit part flat with a simple structure, without installing power separately and bothering a worker's hand.

In order to solve the said subject, the invention of Claim 1 WHEREIN: The fixed cost vehicle lift which made it possible to store a vehicle support in a pit at the time of a lift down so that the upper surface may become the same level as the bottom surface, The pit in the said pit The cover is installed, and the pit cover is supported by standing and falling free footnotes, and the foot cover is evacuated downward by tilting the footnote in conjunction with the descending motion of the vehicle support body to store the vehicle support body. At the same time, the pit cover is raised until the height is equal to the bottom surface by closing the upper surface of the pit by allowing the vehicle support to stand in conjunction with the upward movement of the vehicle support.

In the invention according to claim 1, the footnote is operated to be tilted over by a pushing operation of a member protruding from the rear side of the vehicle support, and automatically to stand up position by an elastic force. It is comprised so that return is possible.

In the invention of claim 3, in the invention of claims 1 or 2, a footnote is pivotally attached to the rear face of the pit cover.

EMBODIMENT OF THE INVENTION Hereinafter, embodiment of the vehicle fixed cost lift which embodied this invention is described in detail based on drawing.

FIG. 1 is an explanatory view showing an example, and FIG. 2 is an explanatory view of the pit cover of FIG. 1, (a) is a plan view, and (b) is a side view. 3 has shown the detail of the A part and B part of FIG. In Fig. 1, reference numeral 1 denotes a cylinder which is a lift body that moves up and down in the vertical direction, and reference numeral 2 denotes a plate which is installed on an upper portion of the cylinder 1 and mounts a vehicle or the like on the vehicle support body. Reference numeral 3 is a buried portion for storing the cylinder 1, and a power for vertically moving the cylinder 1 is provided. Reference numeral 5 denotes a drainage path through which water accumulated in the pit is discharged, and reference numeral 9 denotes a bottom surface. Reference numeral 4 has a size capable of accommodating the plate 2 as a pit, and a pit cover 10 is provided in the opening of the pit 4 to move up and down within the pit.

As shown in Fig. 2, the pit cover 10 is a flat plate and has a hole 11 through which the cylinder 1 is fitted in the center, and six footnotes 13 are axially fixed to the rear surface.

As shown in FIG. 3, the footnote 13 is freely axially fixed to the bracket 20 fixed to the pit cover 10 and has a roller 12 at the lower end, and the upper end to the bracket 20 as shown in FIG. 3. The spring 15 connected to this is provided in parallel. The spring 15 is contracted and provided so that the footnote 13 always returns to the standing posture due to its restoring force, and at the time of standing, the top surface of the pit cover 10 is flush with the bottom surface. .

In addition, the footnote 13 is provided with a longitudinal member 16 (meaning a tilting member) in parallel with the spring 15. The hardness member 16 is an L-shaped rotating member whose upper end is fixed to the bracket 20 by rotating in the counterclockwise direction as shown in the drawing so that the footnote 13 tilts over. Link rods 14 are connected to the lower bent portion 19, and all of the hardness members 16 are connected to each other by a plurality of link rods 14, and all footnotes are formed by any one rotational operation. 13) is to operate at the same time tilted over. The link mechanism 7 is composed of the link bar 14 and the hardness member 16.

In addition, as shown in Fig. 3 (a), the pit cover 10 is provided in the shaft fixing portion 21 of the hardness member 16a of the footnote 13a near the hole 11 through which the cylinder is fitted. Is provided in the through hole 10a, and an operating rod 22 having a standing release knob 17 formed by protruding a bolt upward from the through hole 10a is provided. When the plate 2 is lowered, the standing releasing knob 17 is pushed by the operation protrusion 18 (shown in FIG. 1) provided on the bottom surface of the plate to rotate the longitudinal member 16a, thereby rotating the footnote. (13a) is to be tilted over. In addition, reference numeral 20a is for fixing the footnote 13 to an upright position with a stopper provided in the bracket 20.

Next, the operation of raising and lowering the pit cover will be described. First, since the footnote 13 always tries to maintain the standing state by the extension action of the spring 15, when the lift up operation is performed, the footnote 13 stands up without any special operation in conjunction with the lift up operation, and the pit cover 10 Ascending, the upper surface and the bottom surface 9 of the pit cover 10 are at the same level.

In addition, since the footnote 13 is fixed by the stopper 20a and stabilized in the standing position, the footnote 13 maintains the standing position without unstable or sinking even if an operator or the like rises.

4 is an operation explanatory diagram showing a state in which the lift cover has started to descend, (a) is a side explanatory diagram, and (b) is an enlarged view of a portion C. In the middle of the lift down, the operation protrusion 18 provided on the plate 2 abuts against the standing release knob 17 to lower the standing release knob 17 to rotate the hardness member 16a. Then, the end 16b of the hardness member 16a presses the footnote 13a, and the footnote 13a starts to tilt and fall. Then, by the action of the link mechanism 7, the other hardness members 16 interlock with each other to start the rotation operation, and all the footnotes 13 tilt and fall almost simultaneously. Thereafter, the entire pit cover 10 is pressed by the plate 2 by the lowering force in which the lift is lowered, and the evacuation operation is performed by lowering the inside of the pit in conjunction with the lift operation.

In this way, when the plate 2 is accommodated in the pit 4 and the lowering is stopped when the upper surface of the plate 2 is at the same level as the bottom surface 9, the pit portion becomes flat.

Thus, since the pit cover which moves up and down in conjunction with the up and down of the lift is provided, the pit surface can be at the same level as the bottom surface at the time of lift up and down without any special operation other than the operation of lifting and lowering the lift. Therefore, the operator does not need to open and close the pit.

In addition, since the rise of the pit cover uses the restoring force of the spring and the decrease uses the down action of the lift, it can be operated with a simple configuration without requiring new power.

In addition, since the pit cover descends by tilting the footnotes, the pit cover is formed at a depth corresponding to the length of the footnotes, and an extra depth is not necessary because the pit cover may be relatively shallow. It is easy to clean the inside of the pit because the pit cover and the footnote can be removed at the same time by providing a means, for example, a drainage channel at the lower part of the pit cover, and the foot cover and the footnote can be removed at the same time. easy to do.

FIG. 5 is a diagram illustrating a second embodiment of the present invention, and is a side explanatory diagram of a pit portion that is a main portion. FIG. (a) has shown the time of lift up (slightly lifted up), and (b) has shown the time of lift down. In this embodiment, the footnote 23 is pivotally attached to the bracket 26 provided in the pit bottom plate 30 freely and falling freely, and the upper end of the footnote 23 has the roller 31, and the pit cover 32 The bottom of the) can be moved smoothly.

Then, the footnote 23 is installed in four corners of the pit, and is formed to maintain the standing posture by the restoring force of the parallel contraction spring 25, the upper end of the link mechanism formed by combining the link bar 24 It is connected by interlocking operation. Reference numeral 28 denotes an upright release bar provided at the bottom of the plate 33, and the inclined surface is provided at the end thereof, and the release pin 27 is brought into contact with the release pin 27 provided at the corresponding position of the link mechanism. The foot mechanism 23 is tilted over to move the link mechanism horizontally in the direction. In addition, reference numeral 34 denotes a stopper for fixing the standing of the footnote 23, and a hole in which the standing position of the standing release bar 28 of the pit cover 32 is fitted is provided with a bar.

By doing so, the operation of the pit cover 32 due to the up and down of the lift is performed in conjunction with the restoring force of the contraction spring 25 at the time of lift up as in the above embodiment, and the pit cover 32 is raised to stand up during the lift down. The release bar 28 moves the release pin 27 in the right direction of the drawing to start the footnote 23 inclined and falls, and then the footnote is pressed against the plate 33 by the lowering of the lift and tilted over. The pit cover 32 is evacuated in conjunction with the plate 33 to proceed. Therefore, the pit surface can be made flat even during lift down.

In this manner, the footnotes may be provided on the pit side, whereby the pit cover can be reduced in weight and the detachable operation can be easily performed.

Next, 3rd Embodiment of this invention is described based on FIG. This embodiment is a swing arm type lift, the figure shows the pit part, FIG. 6 has shown the lifted-up state, FIG. 7 has shown the intermediate state of the lift down or lift up, and FIG. 8 has shown the fully lifted-down state.

In the drawing, the same members as in Fig. 5 are given the same reference numerals, and reference numeral 43 shown in Fig. 7 is a swing arm bracket, and a swing arm (not shown) is axially fixed to the upper portion.

As shown, the structure of the pit 4 is the same as FIG. 5, and the footnote 23 etc. are installed in four corners of a pit, and are connected by the link rod 24, and are interlocked. Then, the standing release bar 28 abuts against the release pin 27 provided at the corresponding position in the pit cover 32 to horizontally move the release pin 27 to operate the link mechanism, and tilts the footnote 23 over. It is meant to be thrown.

In this manner, even if the plate portion has a thickness, the foot cover 23 is tilted and the pit cover 32 is evacuated downward, so that the foot 23 and the contraction spring 25 are placed under the pit 4 when lifted down. Since the space should be inclined), the pit surface can be at the same level as the floor surface without increasing the depth of the pit 4.

9 shows the fourth embodiment described above, and shows a pit portion having a structure in which a swing arm is provided on a lift having a doll link.

In this embodiment, the swing arm is provided adjacent to the outer part of the doll lift plate, and the pit cover which accommodates the whole doll lift to a pit and raises and lowers only to a swing arm accommodating part is shown. In addition, the main body of the lift is omitted.

In Fig. 9, the same reference numerals are given to the same members as in Fig. 5, 36 is a pit cover, 37 is a swing arm, 38 is a plate, 42 is a body side bracket, 43 is a swing arm bracket, 44 Is a link bar, 46 is a pit bottom plate, and 47 is a cover. Reference numeral 40 denotes a misalignment prevention bar for prohibiting the left and right movement of the pit cover. The reference numeral 40 is provided at the bottom of the pit cover 36, and the end portion is provided with a through hole 41 provided in the pit cover bottom plate 45. It is inserted into and held in the ground, and the lateral movement of the pit cover 36 due to the inclination of the footnote 23 or the standing operation is prevented, or the shaking when the worker stands up.

Thus, you may provide the pit cover which raises and lowers a part of pit.

In addition, in the above embodiment, a configuration in which the plate on which the vehicle is placed or the swing arm is stored in the pit has been described. However, the present invention does not limit the receiving portion to that, but in the case of a lift having a beam between the plates. The beam can also be included and applied to other members. In addition, it is also possible to change the shape and configuration of each part as appropriate, and to embody it in the range which does not deviate from the meaning of this invention.

As described in detail above, according to the invention of claim 1, since the pit cover is operated by the lifting and lowering motion of the lift, the pit part can be at the same level as the bottom surface not only during the lift down but also during the lift up. The operator can flatten the pit surface without opening or closing the pit.

In addition, since the pit cover is mechanically supported and lifted up and down by the free standing and falling footnotes, there is no need for additional power and the pit needs to be deeper than the height of the footnotes. Therefore, it is easy to drain water in a pit.

According to the invention of claim 2, it is possible to have a simple configuration and to realize it inexpensively.

According to the invention of claim 3, since the pit cover and the footnote can be taken out at the same time, the cleaning in the pit and the like can be easily performed.
