[0001] The invention relates to a parking mechanism for doubling the vehicle accomodation
capacity of already existing flat surfaces, composed of a base, two platforms and
an hydraulic mechanism for platforms' moving, positioned semi underground.
Parking mechanisms of this type, which double the vehicle accomodation capacity,
are known. These mechanisms can only be used when there is no vehicle at the lower
platform. Other parking mechanisms require much bigger excavation than vehicle's height.
[0002] The major advantage of this invention is the ability to park or withdraw vehicles
from or to anyone of the platforms without moving at all the other platform's vehicle.
Another advantage is that the excavation volume has to be smaller than the required
from already known mechanisms.
[0003] It's an object of the present invention to provide a parking mechanism consisted
of two platforms, joined with axles to a vertical steel profile. The vertical profile
has two slides in which are sliding the axles joining the platforms to the vertical
profile. These axles are not kept steady, but they slide in a linear course in order
to minimize the excavation depth and provide small inclination angles to the platforms.
[0004] The system is composed of a base
(1), the lower platform
(2), the upper platform
(3) and the hydraulic folding fan-like elevation mechanism
(4).
[0005] The base
(1) is composed of the horizontal part
(5) and the vertical part
(6). At the horizontal part, there is a construction
(7), on which the piston's upper point is articulated. At the vertical part, there are
two laps,
(8) and
(9), welded at the vertical steel profile. There are also two penetrating slides,
(10) and
(11), formed along the system vertical steel profile-lap.
[0006] The lower platform
(2), consisted of two profiles
(12), where, is an steel plate
(13) positioned. There is also a construction
(14) at the profile
(12), on which is connected the piston's
(15) base upper point. At the profiles' front edge are fastened two holed laps
(16). Two axles
(17) are penetrating the first lap's hole, the slider
(10) and the second lap's hole, for everyone of the two profiles, joining the lower platform
(2) to the base
(1).
[0007] The upper platform
(3) consisted of two profiles
(18), where is an steel plate
(19) positioned. There is also a construction
(20) at the profile
(18), on which is connected the piston's
(15) base lower point. At the profile's front edge are fastened two holed laps
(21). Finally, the axles
(22) join the upper platform to the base
(1).
[0008] The hydraulic folding fan-like mechanism is composed of the piston
(15) and the supporting constructions
(7),
(14) and
(20).
[0009] The construction is partly positioned in a pit in side ground. When the mechanism
is inactive, the upper platform's back edge
(23) is leaned to the ground. In this stage the upper platform can be approached to park
or withdraw vehicles. When there is a need to approach the lower platform, the hydraulic
folding fan-like mechanism turns on. As the elevation starts, the platforms'
(2) and
(3) front edges, start moving, till axles
(17) and
(22) come to the slides'
(10) and
(11) end. Then the platforms'
(2) and
(3) back edges start raising, till lower platform's
(2) back edge reaches ground level
(23). Then the lower platform
(2) can be approached to vehicles for entrance - exit.
[0010] Figure 1 shows the first mechanism's stage, when the mechanism is inactive and upper
platform can be approached.
[0011] Figure 2 shows the second mechanism's stage, when it's at the upper position and
lower platform can be approached.
[0012] Figure 3 shows an intermediate stage, when the platforms' front edge comes to the
slide's upper point and the back edge is ready to start moving.
1. Semi underground mechanism with hydraulic foldind fan-like elevation composed of two
platforms joined to the base through axles and one another through pistons therefore
they kept parallel one another during motion.
The platforms can be accessed by vehicles when the mechanism is at its lower point
(from and to upper platform access) or at its upper point (from and to upper platform
access).
2. Mechanism, as claimed in claim 1, allowing access to and from either of the platforms
without moving at all the vehicle parked to the other platform.
3. Mechanism, as claimed in claims 1 and 2, dividing the loads so, that the platforms'
front edge is always raised first (either there are vehicles parked on the platforms
or not) and after the front edge finishing his movment then the platforms' back edge
is raising and vice versa first lowering the back edge and then the front.
