Definitions
- This invention generally relates to elevator systems. More particularly, this invention relates to a roller guide device for use in an elevator system.
- Elevator systems are well known.
- a cab typically is guided within a hoistway along guide rails that extend vertically within the hoistway.
- Various configurations of guiding arrangements have been developed to provide smooth movement of the cab along the guide rails.
- Typical guiding arrangements include rollers that roll along corresponding surfaces on a nose of the guide rail.
- One challenge facing designers of such devices is to provide for appropriate tolerances in the spacing of the rollers so that smooth movement of the cab is achieved by appropriate cooperation between the rollers and the guide rail nose surfaces. Manufacturing tolerances and variations in the surfaces on the guide rails make it difficult to have one roller guide device design be readily incorporated into a variety of elevator systems.
- This invention provides a unique, self-centering roller guide arrangement.
- this invention is a roller guide device that maintains appropriate contact between rollers and a guide rail and centers the roller guide, which facilitates centering the elevator cab.
- One example roller device designed according to this invention includes a base.
- a roller mount is moveably secured to the base. Rollers are supported on the mount with their axes a fixed distance from each other.
- a biasing member urges the mount into a position where the rollers engage a guide rail without changing the distance between the rollers to establish appropriate roller and guide rail contact and to center the roller guide, which facilitates centering the elevator cab.
- the roller mount is pivotally supported on the base so that it moves about a pivot axis responsive to the bias of the biasing member and responsive to changes in the lateral alignment of the cab with the guide rail.
- the roller mount also supports low friction material inserts that slide along a corresponding surface on the nose of the guide rail.
- a secondary roller is supported by the base and oriented generally perpendicular to the primary rollers so that the secondary roller follows along a corresponding surface on the nose of the guide rail.
- Figure 1 schematically illustrates an elevator system including a guide device designed according to this invention.
- Figure 2 is a perspective illustration of an example embodiment of a roller guide device designed according to this invention.
- Figure 3 is a partial, cross-sectional view taken along the lines 3-3 in Figure 2.
- Figure 4A schematically illustrates selected portions of the embodiment of Figure 2 in a first operating condition.
- Figure 4B schematically illustrates the selected components of Figure 4A under different operating conditions.
- Figure 5 is a planar view taken from the top of Figure 2.
- Figure 6 is a perspective illustration of another example embodiment of a roller guide device designed according to this invention.
- FIG. 1 schematically illustrates an elevator system 20.
- An elevator cab 22 moves along guide rails 24 in a known manner.
- the guide rails 24 are secured within a hoistway, for example, in a conventional manner so that a nose portion 26 of the T- shaped guide rails 24 faces toward the elevator cab 22.
- At least one self-centering roller guide device 30 is supported on the cab to cooperate with each of the guide rails 24. More particularly, the roller guide device 30 includes rollers that roll along the oppositely facing surfaces of the nose portion 26 of the guide rails 24.
- FIG. 2 illustrates one example roller guide device designed according to this invention.
- the guide device 30 includes a rigid base 32, which may be made from steel, for example.
- the base 32 is adapted to be mounted in a fixed position relative to the cab 22.
- a roller mount 34 is moveably supported by the base 32 such that the roller mount 34 can move relative to the base 32.
- a set of rollers 36 are supported on the roller mount 34 using a conventional shaft and bearing arrangement, for example.
- the rollers 36 rotate about axes 38 that are generally perpendicular to the longitudinal axis of the corresponding guide rail 24.
- the axes 38 are generally parallel to the oppositely facing surfaces on the nose portion 26 along which the rollers 36 travel as the cab 22 moves up or down.
- the rollers 36 remain a fixed distance from each other because their axes 38 are fixed relative to the mount 34.
- the roller mount 34 is supported on a shaft 42 such that the roller mount 34 can be pivoted relative to the base 32.
- a biasing member 44 biases the roller mount 34 as shown by the arrow 46 to adjust the position of the roller mount 34 relative to the base 32.
- the roller mount 34 pivots about the shaft 42 responsive to the force of the biasing member 44, the roller axes 38 move according to the arrow 46.
- the roller axes 38 By rotating or pivoting the roller mount 34 in a clockwise direction (according to the drawing) for example, the roller axes 38 both move toward a vertical center of the device 30 (according to the drawing) and, therefore, into engagement with the oppositely facing surfaces of the guide rail nose portion 26.
- the biasing member 44 in the illustrated example includes a threaded adjusting member 47 having a first end 48 and a second end 49.
- the second end 49 is similar to the head of a screw so that the threaded member 47 may be rotated using a conventional screwdriver, for example.
- the first end 48 in the illustrated example includes a nut that is rotationally secured by a support surface 50 on the roller mount 34. Rotating the threaded member 47 changes the distance between the support surface 50 and the second end 49 of the threaded member 47 and compresses a spring 52 a selected amount.
- the spring 52 provides the biasing force to urge the rollers 36 against the rail noise 26.
- the threaded adjustment member 47 allows for manually compressing the spring 52 to draw the roller mount 34 into a position that facilitates installing the roller guide device 30 in an elevator system. Once the cab and roller guide are in a desired position, the adjusting member 47 can be used to adjust the tension or bias of the spring 52, which facilitates maintaining a desired amount of contact between the rollers 36 and the oppositely facing surfaces of the nose portion 26 to achieve a desired ride quality (i.e., smoothness).
- the example biasing member 44 includes the spring 52 that urges the support surface 50 away from a support surface 54 on the base 32.
- the spring 52 allows for resiliently maintaining the roller mount 34 in a desired position.
- a resilient arrangement provides certain advantages so that there is some give or play in the position of the rollers 36 relative to the guide rail nose 26.
- the biasing member urges the guide device 30 into a centered, aligned position relative to the guide rail.
- locking nuts 56 secure the threaded member 47 into a desired position, which maintains a desired tension or biasing force on the roller mount 34. This typically corresponds to both rollers 36 engaging the oppositely facing surfaces of the nose portion 26 on the corresponding guide rail 24 under normal operating conditions.
- the biasing member of the roller guide device 30 serves to maintain the rollers 36 in proper engagement with the guide rail 24. Additionally, the biasing member urges the roller guide device 30 into a centered position relative to the guide rail. The manner in which the roller guide is associated with the elevator cab 22 facilitates centering the cab 22 relative to the guide rails 24.
- Figure 4A schematically shows the rollers 36 in engagement with opposite facing surfaces of the nose portion 26 of the guide rail 24.
- the roller 36A contacts one side of the nose portion 26 while the roller 36B contacts the other side.
- the force of the biasing member 44 urges the rollers 36 A and 36B according to the arrow 46.
- This figure schematically illustrates a position of the rollers and the roller guide device under normal operating conditions.
- a force arrow 60 schematically illustrates a lateral force causing lateral movement of the elevator cab 22.
- Such movement urges the roller mount 34 against the bias of the biasing member 44 as schematically shown by the arrow 62.
- the roller 36A remains in contact with one side of the nose 26.
- the rotation of the roller mount 34 relative to the base 32 against the biasing force of the biasing member 44 results in the roller 36B no longer contacting the corresponding side of the nose portion 26.
- a significant advantage to the inventive arrangement is that the force of the biasing member 44 tends to urge the rollers 36A and 36B back into the position of Figure 4A to realign the roller guide device 30 relative to the guide rail nose portion 26 so that the roller guide 30 is returned to a centered position. Such movement also urges the cab 22 back into an aligned, centered position relative to the guide rails.
- the biasing member urges the cab back into a centered position once the laterally shifting force dissipates.
- the urging force of the biasing member is strong enough to resist lateral movement of the cab up to a chosen force limit.
- the action of the biasing member 44 operates to center the cab in at least one lateral direction (i.e., fore and aft).
- Some example embodiments of this invention also include a centering feature that facilitates maintaining a lateral alignment of the cab in a perpendicular, lateral direction (i.e., side-to-side).
- the example roller mount 34 supports inserts 64 made from a commercially available, low-friction material such as plastic or Teflon.
- the inserts 64 are adapted to slide along an end face on the nose portion 26 of a corresponding guide rail 24. Contact between the inserts 64 and the guide rail nose 26 limits lateral movement in that direction (i.e., side-to-side).
- the example roller mount 34 also includes brace members 66 that operate to limit the amount of counterclockwise (according to the drawings) rotation of the roller mount 34.
- the brace members 66 will engage the opposite surfaces of the nose portion 26 in the event, for example, that the elevator cab tends to move laterally beyond the anticipated resistance provided by the biasing member 44.
- the inventive roller device limits the amount of horizontal or lateral movement of the cab by the resistance provided by the biasing member 44 and, under some circumstances, engagement between the brace members 62 and the guide rail surfaces.
- support surfaces 54 are at the top and bottom of the base 32 extending generally perpendicular to a substantial portion of the body of the base 32.
- One (the top according to the drawings) of the support services 54 includes an opening 68 that receives at least a portion of the adjuster 47 and allows for adjustments to be made conveniently from above the roller guide device.
- Both support surfaces 54 preferably include a recess 70 that is adapted to engage the guide rail in the event of relatively large amounts of lateral cab movement, for example. Under some circumstances, lateral shifting of the cab 22 may urge the roller mount 34 into such a position (such as that shown in Figure 4B, for example) that the side surfaces of the recesses 70 contact a corresponding surface on the nose portion 26 of the guide rail. Under such circumstances, the recesses 70 operate as a sliding type guide as known in the art. In one example, the surfaces of the recesses 70 preferably do not engage the nose portion 26 except under extreme operating conditions.
- sliding guides typically require lubrication along the nose portion 26 of the guide rails.
- the inventive arrangement including the rollers 36 does not require lubrication on the guide rail surface and, therefore, the sliding, guiding operation of the recesses 70 preferably is used only on a very limited basis.
- the sliding, guiding function of the recesses 70 is a back up in the event that one of the rollers 36 should fail to operate as intended.
- the base 32 includes an opening 80 through which a roller 82 at least partially protrudes.
- the base 32 supports the roller 82 so that it rotates about an axis 84 that is generally perpendicular to the axes 38 of the rollers 36.
- the roller 82 is adapted to roll along the terminal surface of the nose portion 26 as the cab moves.
- the roller mount 34' in this example has a different configuration compared to that shown in the example of Figures 2 and 3 to accommodate the roller 82. A variety of configurations are within the scope of this invention.
- the roller 82 facilitates preventing lateral movement of the roller guide device 30, and therefore the cab 22, in a direction that is pe ⁇ endicular to that accommodated by the biasing member 44.
- the example embodiment of Figure 6, therefore facilitates maintaining a centered cab alignment in four lateral directions (i.e., fore, aft, left and right).
- the inventive arrangement provides a self-centering, economical roller guide arrangement that also provides cab-centering features.
- One example embodiment of this invention presents cost savings and better system performance because it utilizes a roller guide arrangement that is as economical to manufacture as a typical slide- guide arrangement.
- the inventive arrangement also provides cost savings because it requires fewer parts, easier installation and simpler adjustment.
