Sliding device
Described herein is a sliding device ( 1 ) designed to receive a vehicle ( 7 ). The sliding device includes a frame ( 5 ) on which the vehicle is intended to be received, at least three sliding wheels ( 3 a - d ) vertically adjustable relative to the frame and each wheel operatively connected to the frame via at least one vertically disposed rotatable shaft ( 9 a - d ), a plurality of vertical folding shafts ( 19 a - d ) connected to the frame, a plurality of cross bars ( 14 a - b, 15 a - b ) elevated relative to the frame, the cross bars are operatively connected to the wheels via the rotatable shafts ( 9 a - d ), and pivotally connected to the frame via the vertical folding shafts ( 19 a - d ) so that each of the cross bars is movable between a folded and an unfolded position ( 3 ), and a folding lock ( 21 ) adapted to lock the vertical folding shaft ( 19 a - d ) relative the frame in the unfolded position to prevent it from being turned.
1. A sliding device designed to receive a vehicle, wherein the sliding device comprises:
a frame on which the vehicle is intended to be received,
at least three sliding wheels vertically adjustable relative to the frame and each wheel operatively connected to the frame via at least one vertically disposed rotatable shaft,
a plurality of vertical folding shafts connected to the frame,
a plurality of cross bars elevated relative the frame, the cross bars are operatively connected to the wheels via the rotatable shafts, and pivotally connected to the frame via the vertical folding shafts so that each of the cross bars is movable between a folded and an unfolded position, and
a folding lock adapted to lock the vertical folding shaft relative the frame in the unfolded position to prevent it from being turned.
2. The sliding device according to claim 1 , wherein the folding shafts are arranged at a distance from and parallel to the rotatable shafts.
3. The sliding device according to claim 1 , wherein the vertical folding shaft is a bolt rotatably connected to the frame.
4. The sliding device according to claim 1 , wherein said folding lock further comprises one or more bolts ( 27 ).
5. The sliding device according to claim 1 , wherein said folding lock further comprises a protruding portion and a receiving portion adapted to cooperate with the protruding portion to lock the vertical folding shaft.
6. The sliding device according to claim 5 , wherein said protruding portion is attached to the frame and said receiving portion is attached to one of the cross-bars.
7. The sliding device according to claim 5 , wherein the protruding portion and the receiving portion are arranged so that the protruding portion faces the receiving portion when the cross-bar is in the unfolded position, and the folding lock further comprises at least one securing member adapted to attach the protruding portion to the receiving portion when the cross-bar is in the unfolded position and thus locking the cross bar to the frame.
8. The sliding device according to claim 5 , wherein each of the protruding and the receiving portions comprises at least one through hole that faces each other when the cross bar is in the unfolded position and the through holes are adapted to receive the securing member, thus locking the cross bar to the frame.
9. The sliding device according to claim 7 , wherein the securing member further comprises two bolts.
10. The sliding device according to claim 1 , wherein the sliding wheels are rotatably connected to the cross bars via the rotatable shafts.
11. The sliding device according to claim 1 , wherein the sliding device comprises hydraulic cylinders adapted to lower and raising the sliding device by decreasing and increasing the vertical distance between the cross bar and the wheel.
