Description

Vehicle Access Structure
Technical Field
The present disclosure relates to a vehicle access structure for a motor vehicle and is particularly, although not exclusively, concerned with reducing the climatic fluctuations upon the opening of a door of a vehicle.
Background
To allow passengers to enter and exit vehicles, such as buses, doors are opened frequently, exposing the interior of the vehicle to the exterior environment.
When the doors are opened, air is exchanged between the interior and exterior of the vehicle through the opening. The airflow is increased by differences in climatic conditions such as temperature between the interior and exterior environment.
To maintain a comfortable internal environment for passengers, heating and/or cooling systems are often installed in vehicles. Frequent opening of doors, which is required, for example for inner city bus journeys, can cause fluctuations in temperature which can put a strain on such systems. These fluctuations create a high energy demand in order to stabilise the climatic conditions of the interior. However, despite the heating and/or cooling systems operating to stabilise the climatic conditions in the vehicle, passengers can still feel uncomfortable climatic fluctuations.
Revolving doors can help to reduce climatic fluctuations, however operating such systems requires a lot of energy. Furthermore, these systems are not adapted for mass entry or exit or wheelchair use and are slow in emergency situations.
There is a need for a low powered system which can enable efficient access to a vehicle in a manner which minimises climatic fluctuations.

Detailed Description
With reference to Figures 1 and 2, the vehicle access structure 2 comprises a closure device 3 in the form of a membrane or belt 4, which forms the sides of the structure. The membrane 4 may be formed of any flexible material and may comprise natural material such as rubber or synthetic material such as polymer. In one possible arrangement the membrane 4 may comprise industrial belting material.
The membrane 4 comprises a first door opening 6 which may be formed as a first aperture in the membrane 4 and a second door opening 8 which may be formed as a second aperture in the membrane 4. The vehicle access structure 2 further comprises three support members 12a,b,c disposed between an interior access opening 9 and an exterior access opening 10 in the form of vehicle passenger entrance 11.
The entrance 11 may be closed by a separate door 13 (shown only in Figure 1).
The apertures in the membrane 4 may have flexible seals delineating the door opening.
The three support members 12a,b,c are arranged to form the indices of an isosceles triangle. It is envisaged that the three support members 12a,b,c may extend upwardly from a floor of the vehicle and may be arranged in any position relative to one another. Each support member 12a,b,c comprises an upper gear 14a and a lower gear 14b which are rigidly fixed at or near the upper and lower axial ends of the respective support member; the rotational axis of each gear 14a,b being aligned with the longitudinal axis of the respective support member 12a,b,c.
The membrane 4 runs over the gears 14a,b of the support members 12a,b,c and comprises rows of slots. A first row of slots 15a is arranged to cooperate with the upper gears 14a and a second row of slots 15b is arranged to cooperate with the lower gears 14b. The rows of slots 15a,b are parallel to one another and orthogonal to the longitudinal axis of the support members 12a,b,c. The gears 14a,b are provided with gear teeth which are configured to be received in the slots in the membrane 4.
At least one of the support members 12a,b,c may comprise a drive shaft, configured to be rotated by at least one motor (not shown) under the action of a controller (not shown). Rotation of the support member 12a causes the upper and lower gears 14a,b to rotate. Since the teeth of the upper and lower gears 14a,b are received into the slots in the membrane 4, torque is transferred through the gears 14a,b to the membrane 4.
In alternative arrangements, gears 14a,b may be rotatable about the support members 12a,b,c. In such arrangements, the gears 14a,b may be rotated without rotation of the support members 12a,b,c.
A ceiling 16 is disposed above the first row of slots 15a and a floor 18 is disposed above the second row of slots 15b. The ceiling 16 may be the ceiling of a vehicle 17 and the floor 18 may be the floor of the vehicle 17. A seal (not shown), such as a weather tight seal, air seal or brush seal may be provided at or towards the upper and lower edges of the membrane to limit or prevent leakage of air between the membrane and the ceiling and/or floor. The seals may be disposed below the first row of slots 15a and above the second row of slots 15b, thereby preventing leakage of air through the slots.
Other seals may be provided to limit or prevent airflow. For example, seals may be provided between the membrane 4 and a wall of the vehicle 17, either side of the entrance 11.
The door 13 may be any door, such as a sliding door configured to slide in the directions D1 and D2.
With reference to Figures 3 to 7, the membrane 4 of the vehicle access structure 2 is movable between a first position, a second position, and a third position.
In the first position, shown in Figures 3 and 4, the membrane 4 is arranged with the first door opening 6 facing the interior of the vehicle 17, the second door opening 8 facing a wall 20 of the vehicle 17 and an imperforate portion 22 covering the entrance 11. When the membrane 4 is in the first position, a person may enter the vehicle access structure 2 from the interior of the vehicle 17 through the first door opening 6.
The membrane 4 is rotatable clockwise about the support members 12a,b,c from the first position to the second position.
In the second position, shown in Figures 5 and 6, the membrane 4 is arranged with the first door opening 6 facing the wall 20 of the vehicle 17, the second door opening 8 facing the entrance 11 and the imperforate portion 22 facing the interior of the vehicle.
When the membrane 4 is in the second position, a person may exit the vehicle access structure 2 to the exterior of the vehicle 17 through the second door opening 8.
The membrane 4 is rotatable anti-clockwise from the second position to the first position.
The entrance 11 may be opened or closed by the door (not shown) whilst the membrane 4 is arranged in the second position.
In the third position, shown in Figure 7, the membrane 4 is arranged with the first door opening 6 facing the entrance 11, the second door opening 8 facing the interior of the vehicle 17 and the imperforate portion 22 facing the wall 20. When the membrane 4 is in a third position, a pathway is formed between the interior of the vehicle 17 and the exterior of the vehicle 17 through the first and second door openings 6,8. This enables quick flow of passengers into and out of the vehicle 17, but has the disadvantage of allowing intermingling of interior and exterior air.
The controller (not shown) may be provided to control the motor (not shown) and thereby control rotation of the membrane 4. The controller may be configured to rotate the membrane 4 between the first, second and third positions. A display (not shown) may be provided to enable a user to select the desired position of the vehicle access structure 2. In some arrangements, sensors may be provided to detect movement, for example, indicating the presence of a passenger at or near a portion of the vehicle access structure 2. Input to the sensors may trigger the controller to rotate the membrane 4 according to the movement and position detected by the sensors.
The controller may be configured to open and close door 13 of the entrance 11 of the vehicle 17. For example, the controller may open the door 13 when the first or second door opening 6,8 is facing the door 13, and close it before the membrane 4 is to be rotated.
When a vehicle 17, such as a bus stops at a bus stop, sensors detect a passenger at the bus stop. The membrane 4 is rotated so that the second door opening 8 faces the door 13. The door 13 is opened. The membrane 4 may rotate synchronously with the opening of the door 13, thereby minimising the time taken for the passenger to gain access to the vehicle 17. The passenger may enter the vehicle access structure 2 through the second door opening 8. The door 13 is closed and the membrane 4 is rotated such that the second door opening 8 faces the interior of the vehicle 17. The passenger exits the vehicle access structure 2 into the vehicle 17.
When a passenger wishing to exit the vehicle 17 is detected by the sensors, the controller rotates the membrane 4 so that the second door opening 8 faces the interior of the vehicle 17. The passenger enters the vehicle access structure 2. The membrane 4 is rotated such that the second door opening 8 faces the entrance 11 and the door 13 is opened. The passenger exits the vehicle 17 and the door 13 is closed.
When a group of passengers are detected at the bus stop, when passengers wish to exit the vehicle in large numbers, or in an emergency situation, the membrane 4 may be rotated such that the first door opening 6 faces the open entrance 11 and the second door opening 8 faces the interior of the vehicle 17.
Steps of the vehicle access method may be controlled by the controller. The controller may determine a suitable rotation of the membrane 4 and the opening and closing of the door 13 according to one or more predetermined gestures or parameters such as fixed time periods and/or movement detected by a sensor. For example, the controller may be configured to close the door and rotate the membrane after a predetermined time interval following the detection of a passenger entering the vehicle access structure 2 from the outside of the vehicle 17.
In some arrangements, the controller may be operable by a user such as a driver and/or passenger of the vehicle 17. The vehicle access structure 2 may comprise two, four or more support members. The vehicle access structure 2 may be retrofitted into an existing vehicle 17.
It is envisaged that other rotary mechanisms may be used to rotate the membrane 4.
In some arrangements, the membrane 4 may comprise one door opening only or more than two door openings. The membrane 4 may be provided adjacent to more than one entrance, For example, another entrance may be provided in the wall 20 of the vehicle 17. The door 13 may be configured to be closed when the imperforate portion 22 of the membrane 4 is rotated to face the opening 9. The membrane 4 may be rotatable clockwise and/or anticlockwise between the first, second, third and/or other positions.
