Abstract

A prefabricated vehicle maintenance apparatus is disclosed, including a housing having bottom, side and end walls, which housing is adapted for insertion within a pit formed in the ground. A horizontal platform is arranged in the housing for supporting a mechanic beneath a vehicle arranged in straddling relation above the pit, the platform normally having effective width and length dimensions corresponding generally with the spacing distances between the housing side and end walls, respectively. The vehicle maintenance apparatus further includes a platform lifting device for vertically displacing the horizontal platform between upper and lower levels relative to the housing bottom wall, at least one of the effective width and length dimensions of the horizontal platform being variable to define an opening affording access to the portion of the housing bottom wall arranged beneath the platform.

Claims

1. Vehicle service apparatus, comprising

(a) a unitary housing including a bottom wall, and opposed pairs of parallel spaced vertical side and end walls, respectively, secured at their lower edges with said bottom wall, said housing being adapted for insertion within a pit formed in the ground, said side walls being spaced a distance less than the spacing distance between corresponding wheels of the vehicle, whereby the vehicle can be positioned in straddling relation above the housing;

(b) horizontal platform means arranged in said housing for supporting a mechanic beneath the vehicle, said platform means normally having effective width and length dimensions corresponding generally with the spacing distances between said housing side and end walls, respectively;

(c) platform lifting means for vertically displacing said platform means between upper and lower levels relative to said housing bottom wall; and

(d) means for varying at least one of the effective width and length dimensions of said platform means to define an opening for providing access to the portion of the housing bottom wall arranged beneath said platform means.

2. Apparatus as defined in claim 1, wherein said platform means includes at least two sections normally arranged in coplanar, longitudinal relation relative to each other, and means connecting a first one of said sections for movement from a first position to a second position relative to the other section, thereby to reduce the effective length of said platform means, whereby said access opening is defined adjacent one of said housing end walls.

3. Apparatus as defined in claim 2, wherein said platform sections are telescopically connected for coplanar, longitudinal adjustment between extended and collapsed conditions relative to each other, and further including spring means biasing said sections toward their extended condition.

4. Apparatus as defined in claim 1, wherein said platform lifting means comprises supporting members connecting said horizontal platform with said housing bottom wall, said supporting members being vertically extendable for vertically displacing said horizontal platform means between upper and lower levels relative to said housing bottom wall.

5. Apparatus as defined in claim 1, further comprising jack means connected with one of said housing side or end walls by means of a flange on said jack means, which flange is insertable in a horizontal slot included in said housing side or end wall, whereby said jack means may be operated to elevate a portion of the vehicle during the servicing thereof.

6. Apparatus as defined in claim 1, further comprising a ventilation system for removing exhaust gases from the housing wherein said ventilation system comprises:

(a) a motor driven exhaust fan located in said housing side walls;

(b) a plurality of exhaust grill panels located in said housing side walls, which grill panels direct gases from the interior of said housing to said exhaust fan; and

(c) a conduit system for directing gases from said exhaust fan to the atmosphere.

7. Apparatus as defined in claim 1, wherein at least one of said housing side and end walls further includes extensible light fixtures.

8. Apparatus as defined in claim 1, wherein at least one of said housing side and end walls further includes fluid dispensing and collection means.

9. Apparatus as defined in claim 1, wherein said housing further includes a retractable cover means for covering the top portion of the housing to provide a surface continuous with the ground in which the housing is inserted.
