Method of functioning the retractable hard top system for convertible vehicles

Abstract

Method of functioning the retractable hard top system for convertible vehicles which implies splitting the ceiling in the middle (through the longitudinal axis of the vehicle), moving the rear window with the frame-like area around it on top of the trunk lid, opening the upper areas of the rear wings and folding compactly the remaining components of the roof inside the lateral areas of the trunk. This method significantly increases the usable volume of the luggage compartment and offers an easier access to the items carried in the trunk. Also, this method requires a less complex operation system which leads to less expensive manufacturing and maintenance costs.

Claims

1. A hard-top convertible vehicle system with two assemblies, each assembly comprising: a horizontal element; a connecting segment; a rear pillar; and a rear wing having a top which opens to provide access to a storage area in a respective lateral part of a trunk of a vehicle, wherein the horizontal elements are symmetric, when the assemblies are extended, the horizontal elements are joined at a seam oriented along a longitudinal axis of the vehicle, and wherein the rear pillars, the connecting segments and the horizontal elements fold compactly so that each assembly enters the respective storage area.

2. The convertible system according to claim 1, wherein the horizontal elements from each assembly detach from one another along the longitudinal axis of the vehicle by raising lateral sides of the respective horizontal elements away from the connecting segment of the corresponding assembly.

3. The convertible system according to claim 2, wherein the system further comprises a panel that includes a frame and a rear window of the vehicle, the panel being movable from a first position in which the frame is fixed above a trunk lid of the vehicle.

4. The convertible system according to claim 3, further comprising two arms that move the panel, wherein, when the two assemblies are disposed in the respective storage areas, a base of each of the two arms is detachable from the frame so that the panel moves together with the trunk lid when the trunk lid is opening or closing.

(14) FIG. 15 is a top left rear end view showing the base of the rear window's moving arms that are detached from the surrounding area when the trunk lid is open.

(15) The present invention provides a method of folding the hard top of convertible vehicles characterized by the fact that the rear window and the frame-like area around it remaining outside the vehicle's body and it is moved and fixed on the trunk lid and the other components of the hard top fold compactly in the left and right sides of the inside of the trunk.

(16) The following describes an embodiment of the invention in connection with FIGS. 1-15:

(17) FIG. 1 is showing the main components of the convertible system with the closed hard top.

(18) The ceiling is composed of identical horizontal elements 2a and 2b, the connecting horizontal segments 3a and 3b, the rear pillars 4a and 4b and the panel 12 formed by the frame 5 and the rear window 6. There are also shown the upper parts of the rear wings 7a and 7b, the trunk lid 8, the articulating connections 13a and 13b of the segments 3a, 3b and the pillars 4a, 4b, the joining area 22 between the elements 2a and 2b, the upper frame of the windscreen 1 and the front pillar 31a.

(19) FIG. 2 is showing the beginning of the opening process by lifting the outer lateral areas of 2a and 2b away from the segments 3a and 3b, achieving at the same time their division in the area 22.

(20) Further, the panel 12 separates from the rear pillars 4a and 4b with the mobile arms 9a and 9b and it is mowed and fixed on top of trunk lid.

(21) The arms 9a and 9b performs a rotational movement toward the rear of the vehicle with rotation points 99a and 99b (FIG. 4 and FIG. 15) and simultaneously the pistons 10a and 10b push up the panel 12 to ensure parallelism with the trunk lid 8.

(22) The base 15a of the arm 9a and the base 15b of the arm 9b (FIG. 15) disengages from the area 99 so that the panel 12 can follow the movement of the trunk lid 8 when it opens and closes with the hard top open.

(23) FIG. 5 shows the final position of the panel 12 when it is fixed to the trunk lid 8. Panel 12 has the same shape as the horizontal part of the trunk lid 8 and closely follows the shape of the inner sides of the rear wings. At the back end the panel 12 forms a small spoiler 11.

(24) FIG. 6 shows the next stage of the opening process when the upper parts of the rear wings 7a and 7b rise following a outward circular motion with the rotation points 14a and 14b.

(25) The assembly composed of the rear pillar 4a, segment 3a and element 2a and the assembly 4b, 3b and 2b detach from the top of the windscreen frame 1 and rise with a circular motion with points of rotation 77a and 77b toward the back of the vehicle (FIG. 8).

(26) When segments 3a and 3b reach a vertical position, the elements 2a and 2b move their inner parts toward the front of the vehicle (FIG. 9). When 3a forms an angle of approximately 90 with 2a and 3b forms an angle of approximately 90 with 2b, the assembly 3a, 2a and the assembly 3b, 2b start a downward rotation with points of rotation 13a and 13b (FIG. 10).

(27) The assembly 4a, 3a and 2a and the assembly 4b, 3b and 2b go into the sides areas of the boot through the apertures provided by 7a and 7b (FIG. 11) following the trajectory imposed by the points of rotation 77a, 77b and 13a, 13b. Their final position inside the trunk is shown in FIG. 12 and FIG. 14.

(28) The opening process of the hard top ends by returning to the closed position of the 7a and 7b (FIG. 13).

(29) The closing process of the hard top runs by following the above steps in reverse order.
