In the installation assembly, the support 32 is an installation plate. mounting plate in such a way that it can rotate against frictional resistance with respect to 27 ◎Case consisting of a suction cup support 32 bolted to 27. Two conventional suction pumps are mounted on the support 52Vc with a lever to actuate the pump. There is cup 36. If you wish, you can use more than two suction power tubes. Ru.

As already understood, the load is secured to the carriage by the suction cup, and When the rail is lifted approximately vertically, the weight of the load is on the mounting plate 27. tends to rotate around the rod 28, resulting in a lever action. This is true The braking contact portion 60 is pressed against the rail 12 and the carriage is moved onto the rail 12. Fix it in place. This feature is 5.For example, when a television receiver is removed from the stand. This is important in cases where the Wheel the truck to the television receiver. Move the suction cup over and over until you can secure it on the screen. Go up the platform.

Then, by tilting the transport vehicle backwards, the TV will be ready as soon as it leaves the TV stand. The weight of the vision receiver is reduced by pressing the braking contact firmly onto the rail 12. It acts to prevent the carriage from moving downward on the rails 17. then transport The car is placed in a position where the rails are parallel to the ground. Raise the installation plate 27. This causes the television receiver to move the carriage against the action of the torsion spring 31 at the foot portion 22. You can slide it along the rail until you can lean against it. desired When raising the carrier to transport the television set to The weight of the image receptor is supported on the foot 22. Suction cup support 320 can rotate ability to point the television receiver in such a way that it can pass through the doorway be able to do so. This means that the television receiver is not picked up from the TV stand. This would not be possible if it had to be held by tiles while facing in a given direction. .

Channel mold 65 is preferably provided in bin 39 projecting laterally from rail 13. The zero frame is shaped and dimensioned to accept the two wheels 38, which are ball bearings. The landing 36 uses a full sliding device to prevent the vehicle 38 from moving sideways. two protruding There are blocks 40, which are divided into individual channels 37. They are each fixed to the rail 16 by protrusions 41 . tension spring or some length A resilient member 42, either of rubber or the like, is adjacent to the stopper 5o. The distal end of the sliding assembly 64 (in this case the sliding A stopper pin 50) VC is fixed through the entire device 64. All sliding devices 34 There is a second stopper 51 running through it, and stoppers 5o and 51 are clearly visible in FIG. Like Kana, all the sliding devices prevent the car from coming off in the longitudinal direction. Transport vehicle is horizontal When the lower surface of the entire sliding device 64 is in contact with the ground, the wheel 21 is in contact with the ground. Note that it is not lower than the points on the periphery of . This feature is a transport vehicle This is required for the ability to climb stairs.

As shown in FIGS. 5 to 7, during the operation of climbing one flight of stairs, the wheels 21 move to the next level. Push the step T1 of the upper step up to the bottom surface of the sliding device 34 that is on the front upper end of the upper step. It is pulled across. The vehicle is then pulled backwards and upwards. and all the sliding devices, which are already pressing firmly against the front upper edge of the stairs, move together with the wheel 38. The block 40 remains in the carriage frame in the direction of the arrow in FIG. 2, thereby pulling the elastic member 42. Take the middle step up the stairs. This is illustrated in Figure 6. During the upward movement of the transport vehicle, the The wheels contact the edge of the stairway on which the slider system rests, as shown in FIG. luck For further upward and rearward movement of the vehicle, the wheels hold the slider device from the edge of the stairs. Raise and push the wheel 38 to the rest position of the slider device by means of the stop pin 50. This results in an elastic return of the slider device. The car that was just about to be released from the stairs was then destroyed by someone else. It is rolled across 2 on the stair tread and the process is repeated.

In the procedure of descending stairs, the carrier should be placed so that the slide device rests on the edge of the stairs. The car rolls over the edge of the stairs that should be descended. Car 38 is stopped at the frame of the transport vehicle. The pin 50 is pressed so hard that it cannot move with respect to the slider device, and As a result, the slider device will move up the stairs until the wheel 21 comes into contact with the step TIK of the next lower step. You will be sliding across the edge of the step. against the movement of the slide device over the edge of the stairway. The frictional resistance from one stage to the next, when combined with a smooth sliding downward action, and control the lowering of the transport vehicle in a controlled, shock-free and easily accomplished lowering. act as a movement.
