Description

Technical Field

[0001] The present invention relates to an aircraft lifting device.

Background Art

[0002] Conventionally, when boarding or alighting from an aircraft without using a boarding bridge, it is necessary to use a tarpaulin for boarding and alighting. Therefore, in order for wheelchair users or people with disabilities to board an aircraft, etc., the user is placed in the lift member of the aircraft lifting device and lifted to the boarding door of the aircraft or lowered from the boarding door to the ground.

[0003] This lift member is lifted and lowered by a lifting device arranged below the lift member.

Disclosure of the Invention

Problems to be Solved by the Invention

[0004] In order for the user to board and alight from the lift member, it is necessary to install a slope. However, since the lifting device arranged below the lift member is arranged, the bottom surface in the usable space inside the lift member becomes higher from the ground, and there is a problem that the angle of the slope becomes steep and movement becomes difficult, or it is necessary to increase the length of the slope.

[0005] Therefore, an object of the present invention is to provide an aircraft lifting device capable of reducing the ground height of the bottom surface in the usable space inside the lift member.

Means for Solving the Problems

[0006] In order to solve the above problems, the invention of the present application provides a base movably, and a lift member is provided to be liftable with respect to the base. A usable space is formed inside the lift member, and the front and rear in the moving direction inside the usable space are opened. A plurality of electric actuators are respectively provided on both side portions orthogonal to the passage direction in the lift member. The upper end of each electric actuator is connected to the top of a lift member and the lower end of each electric actuator is connected to a base, so that the lift member can be raised and lowered by the electric actuator. Effect of the Invention

[0007] According to this device, multiple electric actuators are provided on each side of the lift member perpendicular to the aisle direction, and the upper ends of each electric actuator are connected to the top of the lift member and the lower ends are connected to the base.This makes it possible to keep the ground height of the bottom of the usable space lower than in the conventional technology described above, and to make the angle of the ground-side slope gentler.

BEST MODE FOR CARRYING OUT THEINVENTION

[0009] The best mode for carrying out the present invention will be described with reference to the drawings.

[0010] FIG. 1 is a perspective view showing a movable state of an aircraft lifting device 1 according to the present invention, and FIG. 2 is a right side view of FIG.

[0011] As shown in Figures 3 to 6, the aircraft lifting device 1 has a base 2. Travel tires 3a are provided at the four corners of a pedestal 3 of the base 2, allowing the aircraft lifting device 1 to be moved by human power. The aircraft lifting device 1 may also be made self-propelled by a motor or the like.

[0012] Side walls 4, 4 are provided on both sides of the pedestal portion 3 of the base 2 so as to rise upward from the pedestal portion 3. A first boarding / alighting opening 5 and a second boarding / alighting opening 6 are formed on the front and rear sides of the pedestal portion 3. The second boarding / alighting opening 6 is formed so as to be located higher than the first boarding / alighting opening 5.

[0013] The end of the ground side slope 7 on the side of the base 3 is connected to the end of the base 3 on the side of the first entrance 5 so as to be rotatable in the vertical direction, and the ground side slope 7 is formed to be collapsible. Handrails 7b, 7b are provided removably on both sides of the ground side slope 7. The removed handrails 7b are adapted to be stored in the usable space 12 described later or attached to the outside of the side wall 4.

[0014] A lift member 11 is provided between the side walls 4, 4 and between the first entrance 5 and the second entrance 6 so as to be movable up and down by an electric actuator 13. A usable space 12 is formed inside the lift member 11, and a first opening 12a is formed on the first entrance 5 side of the usable space 12, and a second opening 12b is formed on the second entrance side. In other words, both ends of the usable space 12 in the passage direction are open. A cover member 11a is provided on the lift member 11. The first opening 12a of the lift member 11 can be opened and closed by a door 11b.

[0015] In addition, a rain protection member 9 is provided to prevent rain or the like from hitting the user when moving between the boarding gate 10a of the aircraft 10 and the lift member 11.

[0016] As shown in Figures 4 and 5, a total of four electric actuators 13 are provided between the lift member 11 and each of the left and right side walls 4, two on each side. The electric actuators 13 are provided on both sides perpendicular to the passage direction of the utilization space 12 described below. Note that the number of electric actuators 13 can be set arbitrarily as long as multiple electric actuators 13 are provided between the lift member 11 and each of the left and right side walls 4. The extension and retraction operations of all the electric actuators 13 are synchronized and performed simultaneously.

[0017] The upper end of the electric actuator 13 is connected and fixed to the upper part of the lift member 11, and the lower end of the electric actuator 13 is connected and fixed to the pedestal part 3 of the base part 2. By extending and contracting the electric actuator 13, the lift member 11 can be raised and lowered as shown in Figures 4 and 5.

[0018] In this embodiment, the electric actuator 13 is adapted to raise the lift member 11 to a position corresponding to the height of the boarding gate of a small aircraft, but the electric actuator 13 may also be adapted to raise the lift member 11 to a position corresponding to the height of the boarding gate of a medium-sized or large aircraft, or may be adapted to raise the lift member 11 to a number of heights corresponding to different heights of the boarding gate of the aircraft.

[0019] A storage space 14 is formed at the lower end of the lift member 11, and an aircraft side slope 15 is stored in the storage space 14 so as to be retractable. The storage space 14 is open on the second opening 12b side, and the aircraft side slope 15 can be pulled out from the opening and extended. The aircraft side slope 15 is not connected to the lift member 11.

[0020] The aircraft side slope 15 can extend from the opening of the storage space 14 in the aisle direction of the usable space 12. Furthermore, the tip 15a side of the aircraft side slope 15 can move laterally in the aisle direction of the usable space 12, and can also move up and down. Furthermore, the tip 15a side of the aircraft side slope 15 can rotate horizontally.

[0021] As a result, even if the position of the aircraft lifting device 1 is slightly misaligned with respect to the boarding gate 10a of the aircraft 10, the aircraft lifting device 1 can be easily installed without changing its position.

[0022] As shown in Fig. 7, anti-slip portions 16 are formed on both ends of the aircraft side slope 15 on the first boarding / alighting door 5 side. The anti-slip portions 16 come into contact with the protrusions 14a, 14a formed on both sides of the opening of the storage space 14, thereby preventing the aircraft side slope 15 from extending beyond a predetermined distance and from falling off.

[0023] Foldable wheel derailment prevention parts 17 that protrude upward are formed on both side ends of the aircraft side slope 15. When the wheel derailment prevention parts 17 of the aircraft side slope 15 are folded, the aircraft side slope 15 can be stored in the storage space 14 of the lift member 11. The wheel derailment prevention parts 17 of the aircraft side slope 15 can be kept open in the upward direction.

[0024] The auxiliary slope 20 is provided at the lower end of the lift member 11 on the second opening 12b side so as to be rotatable in the vertical direction. The auxiliary slope 20 is formed so as to have a small step between the upper surface of the installed auxiliary slope 20 and the bottom surface of the utilization space 12. The auxiliary slope 20 can be rotated upward to a stored position and held by the positioning member 21. In addition, the lift member 11 is raised and lowered while the auxiliary slope 20 is held in the stored state, and at this time, the lower portion of the second opening 12b of the lift member 11 is blocked, thereby also serving as a fall prevention device. On both ends of the auxiliary slope 20, a wheel run-off prevention portion 22 that protrudes upward is formed. In addition, when the lift member 11 is lowered and the auxiliary slope 20 is rotated downward, it is installed between the utilization space 12 of the lift member 11 and the ladder 10b, and the gap between them can be eliminated.

[0025] Next, a method of using the aircraft lifting device 1 will be described.

[0026] With the handrails 7a, 7a of the ground side slope 7 removed, it is stored in the usable space 12 or attached to the outside of the side wall 4. As shown in Fig. 1 and Fig. 2, the ground side slope 7 is rotated upward to block the first boarding / alighting entrance 5, the aircraft side slope 15 is stored in the storage space 14 of the lift member 11, and the lift member 11 is lowered with the auxiliary slope 20 in the stored state, so that the aircraft lifting device 1 can be brought into a movable state in which it can be pushed and moved by a person. The door 11b provided at the first opening 12a of the lift member 11 is closed.

[0027] After the aircraft lifting device 1 in this moving state is pushed by a person or towed by a towing vehicle to the designated position where it will be used, the base 3 is fixed to the ground as shown in Figures 3 and 4, the ground-side slope 7 is opened and installed on the ground, and handrails 7a, 7a are attached to both sides of the ground-side slope 7.

[0028] From this state, the auxiliary slope 20 is rotated downward to bring the tip of the auxiliary slope 20 into contact with a predetermined step of the ladder 10b of the aircraft 10, as shown in Fig. 8. The auxiliary slope 20 can eliminate a gap between the utilization space 12 of the lift member 11 and the ladder 10b. When the door 11b provided at the first opening 12a of the lift member 11 is opened, a person using the aircraft 10 can pass through the ground side slope 7, the utilization space 12 of the lift member 11, and the auxiliary slope 20, and use the ladder 10b to board or disembark from the aircraft 10.

[0029] When a person with a disability, a wheelchair user, or their caregiver uses the lift member 11, the user uses the ground side slope 7 to enter the usable space 12 of the lift member 11 after rotating the auxiliary slope 20 upward to the stored state as shown in Fig. 9. The auxiliary slope 20 prevents the user from falling from the usable space 12 toward the aircraft.

[0030] By providing multiple electric actuators 13 between the lift member 11 and each of the left and right side walls 4, and by connecting the upper end of the electric actuators 13 to the upper part of the lift member 11 and the lower end of the electric actuators 13 to the pedestal part 3 of the base 2, it is possible to keep the height of the bottom surface of the usable space 12 lower above the ground than in the above-mentioned conventional technology, and to make the angle of the ground-side slope 7 gentler. This makes it easier for wheelchair users and their assistants to move along the ground-side slope 7 and enter the usable space 12.

[0031] Next, the door 11b provided at the first opening 12a of the lift member 11 is closed, and the door 11b prevents the object from falling from the utilization space 12 onto the slope 7 on the ground side.

[0032] Next, as shown in FIG. 10, the electric actuator 13 is extended to raise the lift member 11 until the bottom surface of the usable space 12 of the lift member 11 is at substantially the same height as the boarding gate 10a of the aircraft 10.

[0033] 10, the aircraft side slope 15 is pulled out from inside the storage space 14, and the tip 15a side is placed inside the boarding gate 10a of the aircraft 10, while the auxiliary slope 20 is rotated downward so that its tip abuts against the upper surface of the aircraft side slope 15. This allows users to move smoothly from inside the utilization space 12 to the boarding gate 10a of the aircraft 10.

[0034] Since the aircraft side slope 15 is not connected to the lift member 11, the tip 15a side can move up and down and left and right. Therefore, even if the position of the aircraft lifting device 1 is slightly misaligned with respect to the boarding gate 10a of the aircraft 10, the aircraft lifting device 1 can be easily installed without changing its position.
