Abstract
This invention is an arrangement for lifting objects and or persons in or out of a vehicle, and storage device so that usable space is not in any way obstructed or taken from the vehicle. An auto-fold platform helps with effective and efficient device storage, as well as a system of parallel arms which are used to move and operate the platform and useful load. This system allows complete platform movement between lower and upper position as well as efficient folding and storage of platform in a specific space underneath vehicle.
Description
-2 ~ 7 PATENT OBJECTI~E
SUMM~RY OF THE INVENTION
This in~ention is an arrangement for ]iftinq objects~ arld o~-persnns, in or out of a vehicle. and storage device -~o tbat usable space is not taken from vehicle. There ar-e two major l~oint~ that are utilizecJ to achieve t-his goal.
. ~n auto-fold platform system, with folding line alorlg width of p]atform~ which helps with efficiel-lt device storar~e.
2. System of parallel arms, which are used to move an(l operate platfor-m and useful load. This system allows platform movement between lower and upper position as well as efficiel--t folding and StQrage of platform in the space underneath vehicle.
BRIEF DESCRIPTION OF THE DR~WINGS
In the accompanying drawings and illustrations the invention in preferred embodiment will now be described in whirh FIG 1. shows a three dimensional view of the abnve said arrar-gement.
FIG 2. shows top view of lifting device.
FIG 3. sl~ows side view upper loading position of ]ifting device.
FIG 4. shows side view of lower loading position of lif-tirlg device.
FIG 5~ shows multiple platfor-m folding views.
.L ~ ~ 3 7 TECHNIC~L - FUNCTION~L DESCRIPTION - SPECIFIC~TIONS
Design aspects for this lift, require the following, subassemblies, and or parts:
l. Platform (1) with safety frame - fence (2), mechanism for folding of front part of platform (3) double hinge (4) and electric motor with power drive for folding of platform (5), consisting of sprockets (6) and (7) and chain (8).
2. System of parallel arms, main drive arms (9), balance arms (10) and assemblies of shafts (11) and platform brackets (23) that connect them to platform, main frame, and drive mechanisms.

.L ~ ~ 3 7 TECHNIC~L - FUNCTION~L DESCRIPTION - SPECIFIC~TIONS
Design aspects for this lift, require the following, subassemblies, and or parts:
l. Platform (1) with safety frame - fence (2), mechanism for folding of front part of platform (3) double hinge (4) and electric motor with power drive for folding of platform (5), consisting of sprockets (6) and (7) and chain (8).
2. System of parallel arms, main drive arms (9), balance arms (10) and assemblies of shafts (11) and platform brackets (23) that connect them to platform, main frame, and drive mechanisms.
3. Main frame (12) with cross members (13) platform electromotor (14) and mechanism for pulling out and storing of platform (l5).
4. Main guide channels (16) and attachment members to vehicle (17).
5. Motor - hydraulic pump (1S) as main drive mechanism, hydraulic hoses (19) and hydraulic cylinders (20) .
~ll parts of the lift are constructed considering users needs ar,d vehicle s characteristics. When not in use lift is stored underneath vehicle, and on vehicles with solid frame chassis between frame beam and floor, and on unibody vehicles on sides of frame members.
Lift is protected from the all elements, and environmental effects and debris by a sheet metal housing. Main guide channels (16) one on each side are connected to vehicle, via cross members (17) as on FIG 1. Shafts (21) two on each side with bearings (22) allow movement of main frame with all parts from transport - stored position to working position and vice-versa.
~llG137 System for horizontal lift movement is designed so that it provides unobstructed action of main frame. When activated, lift starts electromotor (14) action and that via geared rack (15) moves main frame as on outside of vehicle and stops it at outside upper position FIG 2, so that the platform (1) is ready for unfolding.
ElectrQmotor (5) unfolds platform on double hinge ~4) by help of sprockets (6) and (7) chain and system of levers (8) as on FIG 2,3 5. Platform is now at upper loading position as on FIG 2. Ther, by activation of motor, hydraulic pump (18) and system of hydraulic hoses ~19) and hydraulic cylinders (20), main arms (~) platform i5 moved from upper loading position on vehicles floor to lower loading position on ground and vice-versa as on FIG 4. Horizontal levelling of platform is maintained by balancing arm (10) platform brackets (23) that are welded to the platform as on FIG 2,3. When platform is approaching ground level force is exerted on front of platform (3) and that opens front safety flap and loading plate as on FIG 4. When platform is going up again, safety flap (3) retracts back to upper position by help of springs (24) and it locks up with mechanical lock which ensures safety of the user of the lift~
When platform reaches upper loading position and after useful load removed from platform electromotor (5) is activated and front par-t of platform (1) is folded and then by use of electromotor (14) platform together with main frame (12) is moved and stored on guide channels (1~) underneath the vehicle to stored position. This concludes one cycle of this device.
~ll functions of this arrangement are electronically controlled and some of them could be used for auxiliary actions.
