Description

Title of Invention : Rotary parking with multiple entry and exit space in different levels

Technical Field

[0001] This invention relates to a three dimensional housing apparatus specially relates to a mechanical automobile parking facility that uses automobile parking pallets.

Background Art

[0002] Generally, the conventional elevator type parking system is formed of a tower type structure in which a hoist way is formed in the center portion of the same and a plurality of parking rooms are formed at both sides of the hoist way. In this system, the vehicles are parked at the parking rooms and are unloaded from the parking rooms by an elevator mechanism.

[0003] The prior art contains examples of automated parking structures having mechanical system, none of which, however, have provided a solution for the dual access of parking in different level. Such examples are to be found in U.S. Pat. Nos. 5601390; 9631390; 4971506; 6328521.

[0004] The prior art contains some examples of rotary parking system for example the U.S. Application No. US2004015669 is related to a vertical rotating parking which is located above the ground level and has a single vehicle entrance at the ground level in the bottom of the structure.

[0005] In the present document, a rotary housing apparatus discloses inwhich some part of the parking structure can be located above the ground level and the other part is below the ground level and has multi entrance and exit space or gate for the vehicle. The said advantages are achieved by changing the main rail from the common elliptical or discorectangle shape to a semi bow tie shape (or semi infinity shape) in which the width of the main rail at the middle of the structure has reduced.

Summary of Invention [0006] In the parking disclosed in the present document, where half of the structure is above ground level and the other half is below ground level, the main rail in which chains and arms move has been changed to a semi bow tie shape. Some links with a specific geometry are designed to be placed inside the main rail and are placed next to each other and pinned together. The other end of the link is serrated and it is connected to the chain links with pin. The side rollers of the pallet move on the outer rail. In the lower part of the middle rail, there is a chain wheel, which rotates a number of shafts, and causes the movement of chain links in the main rail, and move the pallets. Pallet is a carriage for housing and moving the vehicle and has two middle rollers and some side rollers. Each pallet must have move in alignment mode. When moving the arm or link on the main rail, due to different curves and different radii created in the mechanism, the speed of the pallet is changed and the distance between them is changed consistently. Therefore, an angular acceleration sensor is provided that whenever this acceleration exceeds a certain limit, the engine rotation speed decreases and as a result, the pallet don’t collide to each other.

Technical Problem

[0007] Current mechanized parking have single entrances and exits gate. The said single gate usually located in the lowest part of parking structure. This single gate limits the use and design of this type of parking and the constructors are forced to build these parking in the form of towers on the ground or completely inside the ground. The above-ground structures occupy a lot of useful space and weaken the structure against storms and earthquake. There are also access difficulties and safety problems in the underground parkings. The purpose of this invention is to build a mechanized rotating parking with the possibility of multiple access from the gate as well as from the middle of the parking structure, which allows the variety of designs for above/underground parkings.

[0012] Figure 5 shows a view of the specific link used in the present invention.

Description of Embodiments

[0013] The rotating mechanism in conventional vertical parking is usually done by rails, chains, sprocket wheels, etc. In these type of parking, usually two rails are placed at a certain distance from each other to form a discorectangle/oval geometry and loading operations are performed by rotating the pallets through these rails.

[0014] In this invention, as front side of parking shown in figures 1 and 2, some part of parking structure^ 0) i.e. half of the height of the structure (10) is located underground and the other part is located above the ground level. The vehicle (1) moves in a special place on the ground and enters the parking structure. Main components of backside of the parking structure are similar to front side structure.

[0015] In the parking of the present document, where half of the structure (10) is above ground level and the other half is below ground level, it is not possible to use two parallel rails with a certain distance because when loading, there is not enough space for two cars to enter, so in the present invention, the main rail (12) has been changed so that it has a small width or breadth in the middle of the structure which is close to the ground level.

[0016] Inside the main rail (12) the chain links (18) are located and moving. These said chain links with a specific geometry are designed to be placed inside the main rail (12) and are placed next to each other and pinned together (19). The rail is used for restricting the movement of the chain links(18) in a certain direction. In one embodiment of the invention, the tooth size of these chains is designed according to DIN8196 standard. In the lower part of the middle rail, there is a chain wheel (20), which rotates a number of shafts (22), and this chain wheel causes the movement of chain links (18) in the main rail (12), and move the pallets (28).

[0017] Pallet (28) is a carriage for housing and moving the vehicle and has two similar middle rollers (30) at the top of the pallet and some side rollers (32). In one embodiment of this invention the number of side rollers is eight. Each pallet (28) must have move in alignment mode (exactly horizontal) in which vehicle on the pallet be stable. Due to the bow shape e of the main rail (12), a special piece called a link or arm (24) is designed to create and keep the necessary distance to perform this purpose.

[0018] If the path movement is straight, this link will follow the same route at a specified distance. Inside this link (24) there is a groove (26) in which the middle rollers(30) of the pallet (28) are placed and move in the outer rail (14). The said groove (26) prevents the middle roller(30) of the pallet (28) from coming out of the rail and on the other hand allows the roller (30) to move inside the groove when entering the curved path (bow). In other words, the link (24) moves in a semi infinity path(12) or bow tie direction in which middle of the path is narrower than its both ends . Other grooves (27) on the piece have been made due to the reduction of the weight of the structure. The other end of the link (24) is serrated and the size and number of teeth are determined according to DIN8196 standard and it is connected to the chain links with pin (25). The side rollers (32) of the pallet move on the outer rail.

[0019] When moving the arm or link (24) on the main rail (12), due to different curves and different radii created in the mechanism, the speed of the car pallet (28) is changed and the distance between them is changed consistently. Therefore, an angular acceleration sensor is provided that whenever this acceleration exceeds a certain limit, the engine rotation speed decreases and as a result, two adjacent pallets don’t collide to each other

[0020] Figure 1 shows a front view of a rotary parking structure (10) disclosed in this invention. The upper part of the structure is located on the ground level and the other half is underground. In typical rotary parking examples, the main rail (12) and the outer rail (14) are geometrically similar and spaced apart, and the center pallet roller is moved inside the outer rail (14).

[0021] In this invention, to create enough space for two vehicles to enter the ground, the width or the breadth of the main rail (12) in the middle of the structure^ 0) has been reduced. In order for the pallet to be able to move in an alignment mode, a special link or arm (24) with a horizontal groove (26) is designed so that the pallet roller (30) can move inside the groove when crossing the curves. As shown in the figure 2, the movement path of the links (24) is completely in line with the path of the inner rail(12) which forms a semi infinity form, while the vehicle pallets(28) moves upwards or downward in alignment mode because the middle roller(30) of the pallet moves inside the groove(26).

[0022] A view of the palette (28) is shown in Figure 3. The pallet has two middle rollers (30) and some side rollers (32). The middle rollers (30) move in the groove (26) while the link (24) move inside the rail (14). The side rollers also move on the outer rails and sub-guide rails, causing the car pallet (28) to rotate in the designated direction in alignment mode.

[0023] A view of the chain links (18) used on the main rail (12) is shown in the figure 4. This chain link is designed to fit the parking structure and is not similar in common and existing examples of rotary parkings. The holes on the body of the chain link (19) are where the chain links(18) pin to each other an d one side of the chain link(18) is serrated to engage with sprocket(20). At the bottom of the middle rail is the sprocket (20), which rotates, causing the shafts to rotate, and subsequently moves the chain links(18) located inside the main rail.

[0024] The link or arm (24) has a longitudinal groove (26) to move the middle roller of the pallet (28), the other grooves (27) are designed to lighten the said part. The other end of the link(24) is serrated and holes (25) are embedded in it and the connection point to the chain links(18) is embedded on it. Because one side of the arm(24) is attached to the chain links(18), the links(24) follow the bow shaped path of the main rail (12).

[0025] The loading and unloading of pallets and speed of engine and safety of operation are controlled by a control unit which is known for a person having ordinary skills. [0026] This document introduces a rotating structure for storing objects and goods that can be loaded and unloaded from the lower and middle floors. Since this structure is mostly used for housing the vehicles, the phrase of parking and vehicle is used in this document, and the application of this technology can extend to other areas and for other goods.
