Embodiment Construction

[0022] With reference to the accompanying drawings, the car jack includes:

[0023] - a first pair of arms 1 , 2 , wherein each arm 1 , 2 has a first end hinged up to the top 6;

[0024] - a second pair of arms 3, 4, wherein each arm 3, 4 has a second end and a first end hinged to the lower abutment top 8, the second end being subject to the Constraints on the second ends of the arms of the first pair of arms 1, 2;

[0025] - an actuator 10 for moving the points of said first pair of arms 1 , 2 constrained by said second pair of arms 3 , 4 in rotation closer / further away from each other, to Adjust the distance between the upper abutment top 6 and the lower abutment top 8 .

[0026] According to an embodiment not shown here, the arm 1 belonging to the first pair of arms 1, 2 and the arm 3 belonging to the second pair of arms 3, 4 are hinged to the first side-to-top part (similar to how arms 1 and 2 Hinged up to the top 6). Arm 2 and Arm 4 are constrained in a similar manner...

Abstract

The car jack comprises: a first pair of arms (1, 2), wherein each arm (1, 2) has a first end hinged to an upper striker (6); a second pair of arms (3, 4), wherein each arm (3, 4) has a first end hinged to a lower striker (8), and a second end constrained, with freedom to rotate, to a second end of an arm belonging to the first pair of arms (1, 2); an actuator (10) for moving closer / apart the points where the first pair of arms (1, 2) is constrained, in rotation, to the second pair of arms (3, 4), so as to adjust the distance between the upper striker (6) and the lower striker (8). The arms (1,2, 3, 4) and the strikers (6, 8) are made of a plastic material.

Description

technical field [0001] The present invention relates to a car jack. The car jack is portable and can be stored in the vehicle, and can be used by the user to perform common maintenance operations, such as changing the tires of the vehicle. Background technique [0002] A known type of car jack comprises: four arms, wherein a first pair of arms is articulated to an upper abutment top and a second pair of arms is further articulated to a lower abutment top; an actuator, which actuates The device is usually obtained by means of a screw and a nut and is designed to move the hinge points towards / away from each other to adjust the distance between the upper abutment top and the lower abutment top. The lower truss top rests on the ground and the upper truss roof rests on the vehicle, for example on the lower part of the body. Thus, by manually acting on the actuator, the vehicle can be raised and lowered to perform mechanical repairs, such as changing a tire. These car jacks are...
