FI100963B - Elevator floor solution - Google Patents

Description

The present invention relates to an elevator car floor solution as defined in the preamble of claim 1.

In freight elevators, as well as in passenger elevators, where goods are often transported, the problem is often that the transfer of goods to and from the elevator is cumbersome and time-consuming. This is especially true when using a forklift to load in cramped lobbies or when loading large objects. In addition, there is a risk of damaging the elevator. For example, the body or door frame-10 teas are in danger of being scratched during loading or unloading.

Patent publication FI 52697 discloses an invention in which a carriage moves from an elevator car on rollers out of an elevator car to a floor level and back in the direction of the floor level of the elevator car 15 for loading and unloading the car. The present invention uses the so-called transfer wagons that run along rails when pushed in and out. The elevator is not controlled with the remote control, but by pressing a push button on the elevator control panel. The elevator car is stopped on the level so that the kis-20 homes in the car and on the level are at the same height.

. * Public patent application FI 760924 also mentions an invention in which a carriage comes from a basket along rails to a level.

The elevator car is controlled by the loading surface of the electric trolley on the level • «.. ·. level with the height adjustment device. The transport trolley is • · · · 25 now movable from the elevator car to the rails.

As a solution to the above-mentioned problems, a new type of car floor solution is presented as an invention. The floor solution according to the invention is characterized by what is stated in the characterizing part of claim 1. Some other embodiments of the invention are characterized by what is set forth in the other claims.

* · * * The invention achieves e.g. the following advantages: «« · · »2 100963 - Loading of goods into and out of the elevator car is facilitated by the moving floor.

- The moving floor balances the weight of the load over a wider area in the elevator car when the load is moved into or out of the car, i.e., no large local loads are applied to the car threshold.

- A remote control can be connected to the motor control of the motor moving the moving floor, in which case, for example, a forklift driver can command the floor 10 out of the basket to the floor level and inside the basket from the truck's cab. The motor control can also be connected to the communication network of the elevator system, in which case the functions of the moving floor can be well coordinated with other elevator functions by means of elevator control. In this case, the remote control can be implemented using a data transmission network.

- The invention is equally applicable to actual goods lifts as well as to passenger lifts used occasionally for the transport of goods.

With the aid of the invention, it is possible to more freely design elevator structure solutions for the application. For example, an elevator that moves cars from one level to another can be built so that the car is loaded into the elevator sideways above.

· ... · The invention will now be described in more detail by means of an application example with reference to the accompanying drawing, which shows a leveled elevator according to the invention, • ·; whose basket floor has protruded out of the basket.

• · · · • · • * · • · ·

In the figure, the floor 2 of the elevator car 1 has protruded to the floor level.

• · ·

The floor 2 is moved by one or two hydraulic cylinders 3 and, 30 the movement of the floor is guided in the depth direction of the body 1, for example by a guide rail (not shown). The floor i · · ’· * * moves from the basket 1 to the floor level 4 and from the level back to the basket on the rollers 5. When loading goods into 6 lifts or lifts, the floor is pushed to the level. Pump 3 using cylinder.). 35 pula device and its control unit are located outside the car of the elevator car *, eg on the roof of the car or under the floor. To move the floor to the elevator, instructions are given with the remote control 7.

The remote control 7 also gives other instructions to the elevator, 3 100963 for example level calls and car calls. In this way, the elevator can be called without pressing the level call buttons 8 and the loaded elevator can be sent to the second floor even from outside the elevator car 1. The connection of the remote control 7 to the data network 5 of the elevator system and at the same time, of course, to the elevator system takes place by means of the transceiver devices 11,12 in the platform and car display units 9,10. The elevator functions are coordinated by means of messages transmitted via the data transmission network. The preferred configuration for the communication network 10 is a serial communication network to which actuators performing various functions are connected. In this way, for example, the operation of the elevator doors can be phased in with the movements of the floor 2 without the risk of collision with the floor 2 and on the other hand without additional delays. Especially in passenger elevators, where the transport of goods 15 is only intermittent, it is advantageous to guide the surface of the floor 2 to the same level as the floor level floor. Then, when using an elevator for transporting goods, it is desired that the floor protrude to the floor level, the elevator car 1 must be driven higher by the thickness of the floor 2. By thickness 20 is meant here the height required for the unobstructed passage of the floor out of the basket. This upward movement can take place with the remote control 1 ordered separately. It can also be part of the operation of the elevator control system. For example, so that when * ··. * Instructs the floor 2 to protrude to the level, the elevator motor controller 25 of the elevator first transmits the command to move the car upwards by the thickness of the floor 2!.!. · 'And only then controls the floor: to protrude out of the car. On the other hand, when calling an elevator with a remote control, this message may already include information about the need to · · cause the floor to protrude to a level, in which case the elevator car is delivered to a level so that no height corrections are required to allow the floor to protrude. Elevator control system • · * 'V.' the system monitors, for example on the basis of the location information of the car, • · · \ that only when the car floor 2 is at a suitable height from the floor level 4 • the car floor is allowed to protrude 35 out. The rear part of the floor 2 of the elevator car has a rim 13, which helps to prevent too much loading and foreign objects from getting under the moving floor. The rim 13 can be made high, even so that it would practically form the rear wall of the passenger compartment.

It will be apparent to those skilled in the art that the various embodiments of the invention are not limited to the examples set forth above, but may vary within the scope of the claims set forth below. For example, radio waves or ultrasound could be used instead of visible or infrared light used as a carrier for messages between the remote control and the elevator system. The floor drive, on the other hand, can be a device other than a hydraulic cylinder, for example a motor-driven chain. The movement of the floor during the transition into and out of the basket 10 may also deviate from the direction of the floor level. However, the floor level must remain horizontal at all times, especially when the load is not supported to prevent its horizontal movement.
