Definitions
- This invention generally relates to elevator systems and more specifically to a space efficient elevator system including a guide rail mounted machine and a sheave design that accommodates the guide rail.
- Elevator systems typically include a car and counterweight that move within a hoistway. Roping couples the car and counterweight and supports them as they move.
- a motor drives the rope to raise and lower the car.
- the car typically includes a roller assembly that cooperates with a guide rail to guide the car within the hoistway.
- the motor has been mounted within a machine room disposed at the top of the hoistway.
- Idler sheaves disposed on the elevator car form part of a system of roping for raising and lowering the car along with the counterweight. Roping is threaded through idler sheaves at various location in the system, for example, the elevator car and counterweight.
- the idler sheaves necessarily take up space within the hoistway and the guide rail extends from the interior surface of the hoistway walls toward the elevator car.
- Various machine mounting strategies have been proposed but building and safety codes require sometimes expensive devices and controls.
- Machine room-less elevator systems have been developed that no longer require a separate machine room.
- Machine room-less elevator systems were developed in response to consumer demands for simpler, more efficient use of space dedicated to elevator systems. Even with such systems, there still is need to decrease the space occupied by an elevator system.
- DE-A-1032496 discloses an elevator drive system with guide rollers mounted underneath the car.
- US-A-20020070080 discloses an elevator having cage-side sheaves disposed at four positions on the lower portion of the cage.
- this invention seeks to provide an elevator system having a unique sheave arrangement that accommodates a portion of a guide rail, requires less space within a hoistway and allows more versatility in arranging the components in the system.
- An elevator system according to this invention is defined in claim 1.
- the inventive arrangement of system components provides a more efficient, space saving elevator system.
- an embodiment of this invention is an elevator system 10 including an elevator car 12 supported for movement within a hoistway 14.
- the hoistway 14 includes guide rails 38 positioned on an interior wall 24 of the hoistway 14and mounted to counter-weight brackets 56.
- the counter-weight brackets 56 are mounted to an opposite interior wall 26.
- the guide rails 38 guide movement of the elevator car 12 within the hoistway 14.
- the counter-weight bracket 56 provides a space extending the entire height 42 of the hoistway 14 for movement of a counter-weight 22.
- the counterweight 22 moves when the elevator car 12 moves as known.
- the counterweight 22 is guided by guide rails 40 mounted within the hoistway (shown in Figure 3 ).
- the elevator car 12 and counterweight 22 include sheave assemblies 32, 34 that cooperate with roping 36 and a machine 16 to raise and lower the elevator car 12.
- the sheave assemblies 32 are mounted to a base 48 of the elevator car 12, however, it is within the contemplation of this invention that the sheave assemblies 32 may be mounted on other locations on the elevator car 12 as may be needed as are known to a worker skilled in the art.
- the elevator car 12 also includes roller assemblies 28, 30 disposed on a top and bottom of the elevator car 12 that ride along the guide rails 38 maintaining proper alignment of the elevator car 12.
- the machine 16 of the example elevator system 10 is positioned and supported atop at least one of the guide rails 38, 40. Supporting the machine 16 atop the guide rails 38,40 eliminates the need for a separate machine room required in conventional elevator systems.

Abstract
Description
- This invention generally relates to elevator systems and more specifically to a space efficient elevator system including a guide rail mounted machine and a sheave design that accommodates the guide rail.
- Elevator systems typically include a car and counterweight that move within a hoistway. Roping couples the car and counterweight and supports them as they move. A motor drives the rope to raise and lower the car. Typically, the car includes a roller assembly that cooperates with a guide rail to guide the car within the hoistway. Traditionally, the motor has been mounted within a machine room disposed at the top of the hoistway.
- Idler sheaves disposed on the elevator car, for example, form part of a system of roping for raising and lowering the car along with the counterweight. Roping is threaded through idler sheaves at various location in the system, for example, the elevator car and counterweight. The idler sheaves necessarily take up space within the hoistway and the guide rail extends from the interior surface of the hoistway walls toward the elevator car. Various machine mounting strategies have been proposed but building and safety codes require sometimes expensive devices and controls.
- Recently, machine room-less elevator systems have been developed that no longer require a separate machine room. Machine room-less elevator systems were developed in response to consumer demands for simpler, more efficient use of space dedicated to elevator systems. Even with such systems, there still is need to decrease the space occupied by an elevator system.
- It is desirable to minimize system expenses to conserve hoistway space and allow for easy installation of the elevator car within the hoistway. Further, buildings typically arc not designed to make special accommodations for elevator systems.
- For these reasons it is desirable to design an elevator system adaptable to efficiently utilize hoistway space. This invention addresses these needs.
-
DE-A-1032496 discloses an elevator drive system with guide rollers mounted underneath the car. -
US-A-20020070080 discloses an elevator having cage-side sheaves disposed at four positions on the lower portion of the cage. - In general terms this invention seeks to provide an elevator system having a unique sheave arrangement that accommodates a portion of a guide rail, requires less space within a hoistway and allows more versatility in arranging the components in the system.
- An elevator system according to this invention is defined in claim 1.
- Accordingly, the inventive arrangement of system components provides a more efficient, space saving elevator system.
- The various features and advantages of this invention will become apparent to those skilled in the art from the following detailed description of the currently preferred embodiments. The drawings that accompany the detailed description can be briefly described as follows:
-
Figure 1 schematically shows an elevator system designed according to this invention; -
Figure 2 is a side view of an elevator car including guide rollers and idler sheave assemblies; -
Figure 3 is a top view of the elevator car and counterweight; -
Figure 4 is an enlarged view of the idler sheave assembly of the elevator car and counterweight; -
Figure 5 is an enlarged view of the roller assembly of the elevator car and the sheave assemblies on the counterweight; and -
Figure 6 is an enlarged view of another embodiment of the idler sheave assembly. - Referring to
Figures 1 and2 , an embodiment of this invention is anelevator system 10 including anelevator car 12 supported for movement within a hoistway 14. The hoistway 14 includesguide rails 38 positioned on aninterior wall 24 of the hoistway 14and mounted tocounter-weight brackets 56. Thecounter-weight brackets 56 are mounted to an oppositeinterior wall 26. The guide rails 38 guide movement of theelevator car 12 within the hoistway 14. Thecounter-weight bracket 56 provides a space extending theentire height 42 of the hoistway 14 for movement of acounter-weight 22. - The
counterweight 22 moves when theelevator car 12 moves as known. Thecounterweight 22 is guided byguide rails 40 mounted within the hoistway (shown inFigure 3 ). Theelevator car 12 andcounterweight 22 includesheave assemblies machine 16 to raise and lower theelevator car 12. In the illustrated example thesheave assemblies 32 are mounted to abase 48 of theelevator car 12, however, it is within the contemplation of this invention that thesheave assemblies 32 may be mounted on other locations on theelevator car 12 as may be needed as are known to a worker skilled in the art. Theelevator car 12 also includesroller assemblies elevator car 12 that ride along theguide rails 38 maintaining proper alignment of theelevator car 12. - The
machine 16 of theexample elevator system 10 is positioned and supported atop at least one of theguide rails machine 16 atop theguide rails room-less elevator system 10 is designed to efficiently use hoistway space 14 and eliminate the requirement of a separate machine room. Using a guide rail to support themachine 16 provides the further advantage of minimizing the number of components. - The
elevator system 10 optimizes space use within the hoistway 14. The inventive approach allows theguide rails 38 to be positioned as close to theelevator car 12 as is possible. Thesheave assemblies 32 include aspacing 62 between profiledbelt engaging portions 54, allowing theguide rails 38 to extend closer to theelevator car 12. - The
sheave assemblies 32 are disposed on thebase 48 of theelevator car 12 and at least twobelts 36 thread about the idler sheave assemblies disposed on either side of theelevator car 12 and are fixed at one end to adead end hitch 18 mounted atop one of theguide rails 38. The other end of eachbelt 36 is fixed todead end hitch 20 mounted atop theguide rail 38 with themachine 16 after threading through theidler sheave assembly 34 of thecounterweight 22 and over themachine 16. The illustrated configuration of roping is only one type and it should be understood that other configurations of hoistway roping for raising and lowering theelevator car 12 are within the contemplation of this invention. - Referring to
Figure 3 , each of theguide rails 38 includes amount portion 64 mounted to theinterior wall 24 or to thecounter-weight bracket 56. Extending from therail mount 64 is aguide portion 66. Theguide portion 66 cooperates with theroller assemblies guide portion 66 of theguide rails 38 to extend toward thecar 12 beyond the belt engaging surfaces on thesheave portions 54 of thesheave assemblies 32. Extending theguide portion 66 of eachguide rail 38 betweensheaves 54 of thesheave assembly 32 reduces the amount of space utilized for components of theelevator system 10 to conserve space within the hoistway 14. - The
example sheave assembly 32 includes fourindividual sheave portions 54 supported about acommon shaft 50. Aspacing 62 separates thesheave portions 54 into two separate groups of twoidler sheave portions 54. Each of theidler sheave portions 54 includes an outer diameter 74 (Figure 4 ). Some of theguide portion 66 of eachguide rail 38 extends into thespacing 62 between aplane 72, tangentto the outer diameter 74 of thesheave portions 54; and theshaft 50. Thespacing 62 has a smaller outside dimension than the outside diameter 74 of the sheave portions. In the illustrated example, the outer dimension of theshaft 50 establishes this smaller outside dimension. - Referring to
Figure 4 , theshaft 50 is supported by thesupport member 52 attached to theelevator car 12. Each of thesheaves 54 includes the outer diameter 74. The outer diameter 74 is spaced afirst distance 75 from the axis ofrotation 58. Theguide portion 66 of theguide rail 38 is spaced from the axis of rotation a second distance 77. The second distance 77 is less then thefirst distance 75 such that a portion of the guide rail is within the spacing 62 between sheave portions. In other words, theplane 72 tangent to the outer diameter 74 of thesheave portions 54 extends across thespacing 62 and at least a portion of theguide 66 of theguide rail 38 intersects theplane 72. - Referring to
Figure 5 , theguide rail 38 engages theroller assembly 28 ofelevator car 12. Theropes 36 are shown in relative position to theguide rail 38 androller assembly 28. Theplane 72 tangent with the outer diameter 74 of thesheaves 54 is shown relative to theropes 36 and intersects a portion of theguide rail 38. Mounting theidler sheave assemblies 32 to create the spacing 62through which theguide portion 66 can extend provides increased space for use by theelevator car 12 and efficiently allocates precious and valuable space within the hoistway 14. The increased space within the hoistway 14 provided by this invention accommodates consumer demands for efficient use of hoistway space. - Referring to
Figure 4 , an enlarged view is shown of thesheave assembly 32. Thesheave portions 54 are supported about theaxis 58 by thecommon shaft 50 and includesbearing assemblies 60 mounted within eachsheave portion 54. The bearingassemblies 60 may be of any type known to a worker skilled in the art. In this embodiment, twosheave portions 54 are shown on either side of theguide rail 38 along with correspondingroping 36. - Referring to
Figure 6 , another embodiment of the sheave assembly is shown including threeidler sheave portions 54 on each side of thespacing 62. The number ofsheave portions 54 disposed on either side of theguide rail 38 is application specific and may include two, three, four, or any combinations thereof as required by specific application requirements. - The
counterweight 22 includessheave assemblies 34 similar to thesheave assemblies 32 mounted on theelevator car 12. The guide rails 40 for thecounterweight 22 do not extend between thesheave portions 54 of thesheave assembly 34 mounted on thecounterweight 22 in this example. - The foregoing description is exemplary and not just a material specification. The invention has been described in an illustrative manner, and it should be understood that the terminology used is intended to be in the nature of words of description rather than of limitation. Modifications and variations are possible in light of the above teachings. The preferred embodiments of this invention have been disclosed, however, one of ordinary skill in the art would recognize that certain modifications are within the scope of this invention. It is to be understood that within the scope of the appended claims, the invention may be practiced otherwise than as specifically described. For that reason the following claims should be studied to determine the true scope and content of this invention.
