Abstract

A device for removably attaching a battery of a motor vehicle, including an upper portion including a mechanism for attaching onto a motor vehicle, and a lower portion including a mechanism for connecting to the battery, and including a latch linked with a rotational axis and linked to a piston on which a resilient mechanism acts, so as to enable the two upper and lower portions to be locked together and unlocked from each other by a translation and rotation of the latch.

Claims

1-13. -13. (canceled)

14. A device for removably attaching a motor vehicle battery, comprising:

an upper part comprising a means of attachment to a motor vehicle and a lower part comprising a means of connection to the battery; and

a lock connected to a rotation spindle and connected to a piston on which there acts an elastic means, so as to allow the upper and lower parts to be locked together and unlocked from one another by a translational and a rotational movement of the lock.

15. The device for removably attaching a motor vehicle battery as claimed in claim 14, wherein the means of connection to the battery belonging to the lower part includes a flat surface on which the battery can rest vertically.

16. The device for removably attaching a motor vehicle battery as claimed in claim 14, wherein the elastic means comprises at least one spring, or at least one spring comprising spring washers of Belleville type.

17. The device for removably attaching a motor vehicle battery as claimed in claim 14, wherein the piston forms a plateau which comes to rest against a stop, separate from the plateau, and secured to the rotation spindle.

18. The device for removably attaching a motor vehicle battery as claimed in claim 14, wherein the rotation spindle is substantially vertical and the piston is capable of a translational movement substantially parallel to the rotation spindle.

19. The device for removably attaching a motor vehicle battery as claimed in claim 14, wherein the lower part comprises at least one attachment element for a tool capable of reacting load when the device is operated using this tool.

20. The device for removably attaching a motor vehicle battery as claimed in claim 14, wherein the upper part comprises a substantially flat lower surface comprising an opening onto a hollow volume forming a lock receptacle, and the lower part comprises the lock, the spindle, the piston, and the elastic means.

21. The device for removably attaching a motor vehicle battery as claimed in claim 20, wherein the lower part comprises a volume in which the rotation spindle is mounted with ability to rotate, within which the piston is located, within which is located the elastic means connected to the piston so as to exert a force that opposes upward movement of the piston.

22. The device for removably attaching a motor vehicle battery as claimed in claim 21, wherein the lower part comprises an upper surface comprising an opening through which the rotation spindle passes, the lock being situated above this opening.

23. The device for removably attaching a motor vehicle battery as claimed in claim 14, wherein the elastic means applies a tension greater than or equal to 8000 N on the lock and/or the coefficient of friction between the lock and a part in contact with the lock in the locked configuration is greater than or equal to 0.15.

25. A motor vehicle comprising:

a power supply battery; and

at least one device as claimed in claim 14 for removably attaching its battery.

26. The motor vehicle as claimed in claim 25, wherein the upper part of the at least one removable-attachment device is fixed under a chassis or under a luggage compartment of the motor vehicle.

24. A lower part of a device for removably attaching a motor vehicle battery, comprising:

a means of connection to a battery, and

a lock connected to a rotation spindle and connected to a piston on which there acts an elastic means, so as to allow locking and unlocking with respect to an upper part by a translational and a rotational movement of the lock.
