  • Publication number: 20250242678
    Abstract: An energy store floor system for an electrically drivable motor vehicle includes a floor structure having respective side sills, to the underside of which is fastened a store housing of an energy store for an electrical drive of the motor vehicle, and having respective profile elements, which are arranged along longitudinal sides of the store housing and are fastened to the underside of the respectively assigned side sill. In order to create an energy store floor system with an improved accident behavior in the event of a side impact, the profile elements are connected to the respectively laterally assigned side sill via respective connection devices, which are detachable from the outside inwards when there is a relative movement, caused by an accident, of the respective side sill relative to the assigned profile element in the vehicle transverse direction.

  • Patent number: 8021214
    Abstract: A hand-held power tool has a drive spindle (2) rotatable about a rotational axis (A) and provided at its free end with a clamping flange (3) and a locking thread (4), a locking nut (7) tightenable on the locking thread (4) for securing a disc-shaped tool (5) between the clamping flange (3) of the drive spindle (2) and its clamping surface (6), and a safety spring (9) located between the disc-shaped tool (5) and an inner recess (8) formed in the clamping surface (6) of the locking nut (7), radially preloaded against the locking thread, and having at least one radial, outwardly projecting nose (10), with the disc-shaped tool (5) having at least one, opening radially inwardly and axially extending groove (11) associated with the at least one nose (10).

  • Patent number: 7959497
    Abstract: A hand-held power tool includes a drive spindle (2) rotatable about a rotational axis (A), a clamping flange (3) provided at a free end of the drive spindle (2) and having at least one inner thread (12) that in a mounted condition of the clamping flange (3) on the drive spindle (2), engages in a thread undercut (13) of the clamping flange (2), a locking pin likewise provided at the free end of the drive spindle (2) and having a locking thread (4), and a locking nut (7) tightenable on the locking thread (4) for securing a disc-shaped tool (5) between the clamping flange (3) and the clamping surface (6) of the locking nut (7), with the clamping flange (3) having in its axial region between the disc-shaped tool (5) and an inner recess (8) of the locking nut (7) in which the centering collar (9) of the clamping flange (3) can be partially received at least one radial, outwardly projecting nose (10), and with the disc-shaped tool (5) having at least one, opening radially inwardly and axially extending groove (11)
