System for covering the luggage compartment of a motor vehicle
The invention is a system for covering a luggage compartment having two lateral supports and a front panel pivotably connected to the supports. A rear panel is also pivotably connected to the lateral supports A carriage is slidably mounted on a longitudinal guide rail rigidly connected to a first of the supports. Two cable sections each having an end associated, respectively, with either side of the carriage, and being kept permanently tensioned along a longitudinal axis is also included with a wheel actuated by a motor. The wheel is rigidly connected to the sections in order to allow one or the other, as desired, to be pulled in a longitudinal direction, in order to move the carriage forwards or backwards in order to move the panels to allow access to the compartment or to cover it.
1. A system for covering the luggage compartment of a motor vehicle, the system comprising:
two lateral supports,
a front panel pivotably connected to the supports about a first transverse shaft positioned along the front edge of the panel,
a rear panel pivotably connected to the supports about a second transverse shaft, the second shaft being slidably mounted longitudinally with respect to the supports,
a hinge connecting the rear edge of the front panel to the front edge of the rear panel about a third transverse axis of rotation, the hinge being arranged so that, when force is applied to the second shaft in a forward direction, the panels are caused to rotate in an upward direction, causing them to transition from a covering configuration, in which they lie horizontally as an extension of each other, to an access configuration for accessing the compartment, in which they are folded against each other,
the system further comprises:
a first carriage receiving a first end of the second shaft, the carriage being slidably mounted on a first longitudinal guide rail rigidly connected to a first of the supports,
a first and a second cable sections, each having an end associated, with either side of the carriage, and being kept permanently tensioned along a longitudinal axis,
a wheel actuated by a motor, the wheel being rigidly connected to the cable sections and adapted to be pulled in a longitudinal direction, in order to move the carriage forwards or backwards in order to move the panels into the access configuration or the covering configuration.
2. The system according to claim 1 , wherein the wheel comprises two grooves arranged in levels axially with respect to the axis of rotation, each of the grooves receiving by winding a first and a second respective cable defining respectively the first and second cable sections, the cables winding in two opposite directions in the grooves in wherein the rotation of the wheel causes a winding of one and a corresponding unwinding of the other.
3. The system according to claim 2 , further comprising two pulleys mounted on the first support at respective ends of travel of the first carriage, the wheel being arranged substantially between the pulleys, each of the pulleys forming a return for each of the cables to keep the sections permanently tensioned.
4. The system according to claim 2 , further comprising a pulley mounted on the first support at a travel end of the first carriage, the wheel being arranged at the other end of the travel, the pulley forming a return for one of the cables to keep the sections permanently tensioned.
5. The system according to claim 1 , wherein the wheel comprises a groove for receiving a cable, the end parts of the cable defining the first and second cable sections, the system further comprising a pulley mounted on the first support at a travel end of the first carriage, the wheel being arranged at the other end of the travel so that the cable forms a tight loop passing around the wheel and the pulley so as to keep the sections permanently tensioned.
6. The system according to claim 1 , wherein the access configuration corresponds to a lifting of the panels by about 90° with respect to the position thereof in the covering configuration.
7. The system according to claim 1 , wherein a second end of the second shaft is mounted on a second carriage, the carriage being slidably mounted on a second longitudinal guide rail rigidly connected to a second support.
8. The system according to claim 1 , wherein one end of the second shaft mounted on a carriage is mounted so as to be removable.
9. The system according to claim 1 , wherein the rear end of each rail is arranged so that when the panels are in the covering configuration, and when observed laterally, the lower angle defined by a first straight line connecting the second and third shafts, and by a second straight line connecting the first and third shafts, is less than 180° so that a force exerted forwards on the second shaft by the first carriage causes the panels to rotate for transition to the access configuration.
