TROLLEY FOR WORKING UNDER AUTOMOBILE

摘要

FIELD: transport engineering; maintenance and repair of automobiles. SUBSTANCE: proposed trolley has bed with wheels and head rest whose rods are connected to bed for rotation around horizontal axle installed in bracket below bed plane. Clamp is installed between rods for rotation around horizontal axle. Clamp has support member engaging with support section of bed. Projection of horizontal axle of rotation onto bed plane is located on support section to provide locking of head rest in working position. To provide folding of head rest, sum of distances from horizontal axle of rotation of clamp to axle of rotation of head rest rods and to upper edge of its support member exceeds distance from axle of rotation of head rest rods to upper edge of bed support section. Minimum inner size of clamp support member in direction of axles of rotation exceeds maximum width of bed support section. Head rest is folded under bed plane and is secured by lock located on lower side of bed. Angle of inclination of head rest to bed plane can be adjusted by re-placing of axles in rod holes. EFFECT: reduced overall dimensions of trolley in non-operating position at reliable locking of head rest in operating and travelling positions of trolley. 2 cl, 4 dwg
