Abstract:
The present invention relates to an extendable vehicle rack arrangement (10) comprising a first and a second load carrier foot (3, 4) and comprising a stationary part (12) attached to said first and second load carrier foot (3, 4) and a displaceable part (11). The stationary part (12) is pivotally connected to at least one of the load carrier feet (3, 4). The extendable vehicle rack arrangement (10) is advantageously an extendable vehicle top rack arrangement. The present invention provides for a solution which effectively reduces or neutralizes the intrinsic forces which can be imparted to an extendable vehicle rack arrangement during or after attachment to a vehicle, thereby providing an easier extension of the displaceable part (11).

The load carrier (10) optionally comprises a protective housing (40) adapted to receive and cover at least parts of a cord (31, 38) which is adapted to extend between the load carrier and the vehicle. The cord has a retracted position and an extracted position. At least parts the cord (31, 38) is adapted to be retracted into the protective housing (40) to the retracted position using a retraction force, the retraction force is imparted by a retraction member (50, 51) or by the cord (31, 38).
Abstract:
A coupling device (1) for coupling a load carrier to a towing hook (2) of a vehicle, which device comprises, a first coupling element (4) adapted to abut against a first portion of the towing hook (2) and a second coupling element adapted to abut a second portion of the towing hook (2). A frame (10) is arranged to accommodate at least the first portion of the towing hook (2) and a transfer linkage (12) for effecting displacement of the first coupling element (4) with respect to the frame (10). The first coupling element (4) is movably connected to the frame (10) and is associated with an end of the transfer linkage (12). The transfer linkage (12) comprises a first two-bar linkage (22) and a second two-bar linkage. The first and second two-bar linkages (22) are arranged in relation to each other such that when a force is applied to the second two-bar linkage the force is transferred via the first two-bar linkage (22) to the first coupling element (4) via the said end of the transfer linkage (12) for releasing or engaging the towing hook (2). Link bars of the two-bar linkages are in a defined angular relationship when the towing hook is engaged. A load carrier and use of a load carrier are also presented.
Abstract:
The present invention relates to a load carrier foot (1) for mounting at least a part of a load carrier to a first surface (2) of a vehicle. The load carrier foot (1) comprising a support member (3), arranged to abut the first surface (2), a gripping member (5) having a first part (16) arranged to abut the vehicle at a distance from the support member (3), an intermediate member (9) between the support member (3) and a second part (17) of the gripping member (5), and an adjustment member (7) acting on the intermediate member (9) to adjust a clamping force between the support member (3) and the first part (16) of the gripping member (5). The intermediate member (9) cooperates with the second part (17) of the gripping member (5) at a first working point (10) and the intermediate member cooperates with the support member (3) at a second working point (11) located at a distance (D) from the first working point (10). The distance (D) between the first and the second working points (10, 11) can be changed by moving at least a part of the intermediate member (9) via the adjustment member (7), to thereby vary the clamping force between the first part (16) of the gripping member (5) and the support member (3). The present invention provides for a space saving arrangement and an arrangement which has improved safety aspects.

Disclosed is a clamp mechanism mountable to a coupling device having a tow ball supported by a tow ball neck. The clamp mechanism comprises a ball retainer having a ball support surface contactable at least to a first area of the tow ball located opposite to the tow ball neck and at least two clamp members which are distributed about a center axis of the ball support surface. Each of the clamp members is movably arranged with respect to the ball retainer and has a ball clamping surface contactable at least to a second area of the tow ball located on the side of said tow ball neck. The clamp mechanism further comprises a tensioning member arranged movably along the direction of the center axis with respect to the ball retainer and interacting with each of the clamp members such that by applying a force to the tensioning member, a clamping force acting between the ball support surface and the ball clamping surfaces to the tow ball is achievable.
Abstract:
The present invention regards nano surfaces and particularly a gradient based nano surface. According to embodiments of the invention a surface bound gradient is created by distributed nanoparticles along a plane surface. This procedure greatly reduces the number of prepared surfaces needed, as well as the methodological error of analysis of adsorption and adhesion phenomena.
