Abstract

A car door separating and attaching device includes a base, a jack mounted on the base, an angle adjusting base and a clamp frame mounted on the jack. The angle adjusting base adjusts the angle of the clamp frame to suit to the door of a car, and the jack lifts them to a height needed. Then the distance between two clamp rods of the clamp frame and then the distance between the two clamp rods and a lateral tube are adjusted according to the size of the door of a car to be separated or attached. Thus the door or tailgate of a car is securely clamped by the device, permitting only one worker perform separating or attaching work with easiness and convenience.

Claims

1. A vehicle door separation and attaching device comprising:

(a) a base (1);

(b) a jack (2) having an output shaft (22) displaceable in a vertical direction;

(c) an angle adjusting base (3) having a fixed base member (31) mounted to an upper end of said output shaft (22), said angle adjusting base (3) including a connecting rod (32) rotatably coupled to said fixed base member (31) and a curved guide member (34) having an arcuate guide slot (341), said curved guide member (34) coupled on opposing ends thereof to said fixed base member (31) and a vertically directed fixed arm member (33), said fixed arm member (33) being rotatably coupled to said fixed base member (31) and fixedly secured to said connecting rod (32); and

,

(d) a clamp frame (4) having a sleeve member (41) telescopingly coupled to an extension tube (44), said sleeve member (41) being fixedly secured to said connecting rod (32) and displaceable therewith, said clamp frame (4) including a pair of position base members (411,

     412) slidably mounted on said sleeve member (41) and adapted to be adjustably coupled thereto, each of said position base members (411,

     412) having a respective clamp rod member (42,

     43) extending therefrom, each of said clamp rod members (42,

     43) having a respective cushion member (421,

     431) fixedly secured to one end of each of said clamp rod members (42,

     43), said clamp frame member (4) further including a lateral tube member (45) fixedly secured to one end of said extension tube (44) and telescopingly coupled to a pair of auxiliary rod members (451), and a pair of L-shaped position plates (456) releasably secured to a respective one of said auxiliary rod members (451) for adjustably fixing a displacement distance between said L-shaped position plates (456) whereby said clamp frame (4) is reversibly vertically displaceable by said jack (2) and rotatably displaceable about an axis perpendicular to said vertical direction and said clamp rods (42,

     43) and said L-shaped position plates (456) may be linearly and adjustably displaced along said sleeve member (41) and said auxiliary rods (451) respectively.

2. The vehicle door separation and attaching device as recited in claim 1 where at least one of said cushion members (421, 431) includes a V-shaped notch (432) formed therein for securing a glass window of said vehicle therein.

3. The vehicle door separation and attaching device as recited in claim 1 including a clamp hook rod (46) mounted on said sleeve member (41), said clamp hook rod (46) having a hook member (461) for hooking to a latch member of a vehicle tailgate.

4. The vehicle door separation and attaching device as recited in claim 1 including a tailgate support rod (5) mounted on said auxiliary rod (451) for supporting a tailgate of a vehicle.

5. The vehicle door separation and attaching device as recited in claim 4 where said tailgate support rod (5) has a support rod cushion member fixed to an end thereof for protection of said tailgate of said vehicle.

6. The vehicle door separation and attaching device as recited in claim 1, where said base (1) is rollingly displaceable on a base surface.

7. The vehicle door separation and attaching device as recited in claim 6 where said base (1) includes a plurality of wheel members (11) mounted thereto for rolling engagement with said base surface.
