Description
ENERGY-SAVING ELEVATOR
TECHNICAL FIELD
[0001] The present disclosure, generally, relates to mechanical engineering. The present disclosure particularly relates to traction elevators and, more particularly, relates to an energysaving elevator in which the torque can be changed on both sides of the elevator i.e., the weight side and the elevator cabin side.
BACKGROUND ART
[0002] In traction elevators, in order to reduce the force on the elevator motor, an anchor with a fixed weight may be placed on one side of the elevator, and the elevator cabin may be placed on the other side of the elevator. In typical traction elevators, the torque radius on the weight side of the elevator is equal to the torque radius on the other side of the elevator. This premise has been seen as the basic design principle of typical traction elevators. On the other hand, if the torque can change on both sides, with a fixed mass (elevator anchor) and a variable mass (elevator cabin wit the variable weight of passengers and loads) and changing the torque on both sides, the torques may increase or decrease.
[0003] Several methods are, generally, used in elevators to reduce electricity consumption, which some of them are as follows: 1. Using weights to reduce the gravitational force that is applied to the elevation motor. 2. The use of engines without a gearbox to reduce the energy consumption of the engine. 3. Using two axles with two separate wheels to reduce the force on the elevator motor. 4. Using a variety of frequency control inverters (to control the optimal speed of the engine at the start and steps of the engine). However, none of these systems are
quite satisfactory. There is, therefore, a need for an energy-saving elevator with a high efficiency which is low cost and easy to manufacture.

It is intended by the following claims to claim any and all applications, modifications and variations that fall within the true scope of the present teachings.
[0048] Unless otherwise stated, all measurements, values, ratings, positions, magnitudes, sizes, and other specifications that are set forth in this specification, including in the claims that follow, are approximate, not exact. They are intended to have a reasonable range that is
consistent with the functions to which they relate and with what is customary in the art to which they pertain.
[0049] The scope of protection is limited solely by the claims that now follow. That scope is intended and should be interpreted to be as broad as is consistent with the ordinary meaning of the language that is used in the claims when interpreted in light of this specification and the prosecution history that follows and to encompass all structural and functional equivalents. Notwithstanding, none of the claims are intended to embrace subject matter that fails to satisfy the requirement of Sections 101, 102, or 103 of the Patent Act, nor should they be interpreted in such a way. Any unintended embracement of such subject matter is hereby disclaimed.
[0050] Except as stated immediately above, nothing that has been stated or illustrated is intended or should be interpreted to cause a dedication of any component, step, feature, object, benefit, advantage, or equivalent to the public, regardless of whether it is or is not recited in the claims.
[0051] It will be understood that the terms and expressions used herein have the ordinary meaning as is accorded to such terms and expressions with respect to their corresponding respective spaces of inquiry and study except where specific meanings have otherwise been set forth herein. Relational terms such as first and second and the like may be used solely to distinguish one entity or action from another without necessarily requiring or implying any actual such relationship or order between such entities or actions. The terms “comprises,” “comprising,” or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. An element proceeded by “a” or “an” does not,
without further constraints, preclude the existence of additional identical elements in the process, method, article, or apparatus that comprises the element.
[0052] The Abstract of the Disclosure is provided to allow the reader to quickly ascertain the nature of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims. In addition, in the foregoing Detailed Description, it can be seen that various features are grouped together in various implementations. This is for purposes of streamlining the disclosure, and is not to be interpreted as reflecting an intention that the claimed implementations require more features than are expressly recited in each claim. Rather, as the following claims reflect, inventive subject matter lies in less than all features of a single disclosed implementation. Thus, the following claims are hereby incorporated into the Detailed Description, with each claim standing on its own as a separately claimed subject matter.
While various implementations have been described, the description is intended to be exemplary, rather than limiting and it will be apparent to those of ordinary skill in the art that many more implementations and implementations are possible that are within the scope of the implementations. Although many possible combinations of features are shown in the accompanying figures and discussed in this detailed description, many other combinations of the disclosed features are possible. Any feature of any implementation may be used in combination with or substituted for any other feature or element in any other implementation unless specifically restricted. Therefore, it will be understood that any of the features shown and/or discussed in the present disclosure may be implemented together in any suitable combination. Accordingly, the implementations are not to be restricted except in light of the attached claims and their equivalents. Also, various modifications and changes may be made within the scope of the attached claims.
