Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a jack bracket for an automobile, which is particularly useful when it is desired to increase the lift amount such that the automobile is jacked up when the wheels fall into a groove. .

[Prior Art] Conventionally, as shown in FIG. 9, a member under the floor of an automobile (1)
Alternatively, a bracket (2) for abutting the jack when the automobile is jacked up is fixed to the frame by welding or bolts.

[Problems to be solved by the invention]

Since the jack bracket (2) is fixed to the member or frame as described above, when trying to increase the lift amount when jacking up by lowering the ground height, the bracket (2) protrudes from under the floor and the load clearance is increased. It will be easier to contact the convex parts of the road and the appearance will be worse,
If the ground clearance is increased, the lift amount at the time of jacking up becomes small, which is inconvenient when a large lift amount is required, such as when a vehicle wheel falls in a groove.

[Means for solving problems]

The present invention provides a jack bracket (12) which is attached to a member (11) or a frame (21) under the floor of an automobile from below as means for solving the above conventional problems. Is a bottom plate (13), both side walls (14) and (14) rising from both side edges of the bottom plate (13), and both side walls (14) and (1
4) Flange-shaped backing plate (1
5) and 15), the jack bracket (12) provides an automobile jack bracket rotatably mounted on a shaft (17) which is vertically movable on a member (11). It is a thing.

[Action]

Under normal conditions or when the lift amount for jack up is small, attach the jack bracket (12) to the member (11) or the frame (21), and then attach the jack bracket (12).
Raise the ground clearance of. When a jack up with a large lift amount is required, slide the shaft rod (17) downward and then rotate the jack bracket (12) by about 90 ° to remove the member.
(11) or frame (21) on the underside of the jack bracket
The ground level of the jack bracket (12) is lowered by abutting the receiving plate (15) of the (12).

[Effect of device]

Therefore, in the present invention, the jack bracket does not normally project from under the floor of the automobile, the load clearance is sufficient, the bracket is less likely to contact the convex portion of the passage, and the appearance is good, and a large lift amount can be obtained when necessary.

〔Example〕

The present invention will be described with reference to an embodiment shown in FIGS. 1 to 6, in which a member (11) under the floor of a vehicle is covered with a jack bracket (12) from below. The jack bracket (12) has a bolt hole (13) A in the center, and a bottom plate (13) in which a supporting piece (13) B. (13) B is inserted obliquely downward from the front and rear ends, and the bottom plate (13). Side walls (14), (14) rising from both edges
And flange-shaped receiving plates (15) and (15) extending from the upper edges of the side walls (14) and (14) to the left and right, and standing from the front and rear ends of the receiving plates (15) and (15). The jack bracket (12), which is composed of the upper engaging pieces (16) and (16), is welded to the member (11) through the bolt hole (13) A of the bottom plate (13). By screwing a bolt (17), which is an axial rod, onto the member (18), the member (1
Installed in 1).

When the jack bracket (12) is not in use or the lift amount when jacking up is not large, the jack bracket (12) is closely attached to the member (11) as shown in FIGS. 1 and 2. Keep the height high. In this state, the jack bracket (12) does not protrude from the member (11). Next, when jacking up requiring a large amount of lift, loosen the bolts (17) to reach the state shown in FIGS. 3 and 4.
(12) is lowered, and then the jack bracket (12) is rotated 90 ° as shown in FIGS. 5 and 6 to rotate the bolt (1).
Tighten (7) and bring the back plates (15) and (15) of the jack bracket (12) into contact with the bottom surface of the member (11). In this state, the jack bracket (12) projects from the member (11) and the ground clearance becomes low. Therefore, as shown in FIG. 6, put the jack (19) on the bottom plate (13) of the jack bracket (12) to jack up. A large lift amount can be obtained. The load at this time is received by the receiving plates (15) and (15) of the jack bracket (12) and does not act on the bolt (17), so that the bolt (17) is prevented from being broken.

Another embodiment is shown in FIGS. 7 and 8. In the present embodiment, the jack bracket (12) of the previous embodiment is attached to the frame (21) movably up and down by a bolt rod (20) having no thread groove through a bolt hole (13) A of the bottom plate. That is, the bolt rod (20) is slidably fitted in the hole (21) A on the bottom surface of the frame (21) and is urged upward by the elasticity of the spring (22). The spring (22) is the seat of the bolt rod (20).
Passed between (20) A and the bottom of the frame (21). In this embodiment, the jack bracket (12) is manually pulled down from the state of FIG. 7 against the elasticity of the spring (22) to the state of FIG. 8 and then rotated by 90 ° as in the previous embodiment. When released, the jack bracket (12) will be supported by the elasticity of the spring (22).
The ground height is lowered until (15) and (15) are brought into contact with the bottom surface of the frame (21).
