ASSISTED POSITIONING DEVICES FOR OVEN RACKSCROSS-REFERENCE TO RELATED APPLICATIONS
[0001] This application claims the benefit of U.S. Provisional Application No. 63 / 729,173, filed December 6, 2024, and U.S. Provisional Application No. 63 / 830,181, filed June 25, 2025, each of which are hereby incorporated by reference in their entirety.BACKGROUND
[0002] In traditional oven systems, one or more racks (e.g., oven racks) may be vertically adjustable within the oven. However, in order to adjust the position of the oven rack, a user typically must remove the oven rack from the oven and replace the oven rack at the new, desired position. This process may be time-consuming, dirty, and, in some cases, the oven racks may be large or heavy, which may make adjustment of the oven rack difficult.SUMMARY
[0003] According to one aspect of the present disclosure, an oven rack adjustment system can include a frame and an oven rack secured to the frame via an oven rack support and a latch. The latch can include a pin that is biased toward engagement with the frame to prevent movement of the oven rack and a handle that is moveable between a first handle position and a second handle position to move the pin out of engagement with the frame and permit movement of the oven rack. The system can include a force reduction assembly, including a roller and a biasing element secured between the roller and the oven rack support, the biasing element to bias the roller into contact with an angled guide of the frame and urge the oven rack in a vertically upward direction.
[0004] In some examples, the frame can include a first post and a second post, and the pin can be configured to engage with teeth extending from at least one of the first post or the second post.
[0005] In some examples, the latch can include a biasing element to bias the pin toward engagement with the frame.
[0006] In some examples, the oven rack support can include a rack slide to permit telescopic movement of the oven rack transverse to the frame.
[0007] In some examples, the rack slide can include a first rail connected to the oven rack and a second rail connected between a first post and a second post of the frame.
[0008] In some examples, the system can include a retention mechanism positioned on the frame and configured to engage a protrusion extending from a sidewall of an oven to secure the oven rack adjustment system within the oven.
[0009] In some examples, the retention mechanism can include a catch plate defining a retention channel configured to receive and retain the protrusion and a biased retention arm arranged to block the protrusion from leaving the retention channel.
[0010] In some examples, the system can include one or more linear bearings secured to the oven rack support, the linear bearings to slide along a corresponding guide rod during movement of the oven rack.
[0011] According to another aspect of the present disclosure, a method of adjusting a position of an oven rack within an oven can include providing an oven rack adjustment system having a frame, a rack support securing an oven rack to the frame, and a latch. The method can include actuating the latch from a locked position to an unlocked position to permit movement of the oven rack relative to the frame. The method can include moving the oven rack along the frame, with a biasing element applying a biasing force to a roller to guide the roller along an angled guide and reduce a force required to move the oven rack. The method can include releasing the latch to automatically return the latch to the locked position and secure the oven rack at a desired position.
[0012] In some examples, actuating the latch can include moving a handle of the latch toward a crossbeam of the rack support to disengage pins of the latch from posts of the frame.
[0013] In some examples, the posts can include teeth extending therefrom to engage the pins of the latch when the latch is in the locked position.
[0014] In some examples, the method can include telescopically extending the oven rack transverse to the frame using rack slides to permit access to the oven rack.
[0015] In some examples, the method can include maintaining alignment of the oven rack during movement using linear bearings that slide along guide rods to mitigate binding or catching during movement of the oven rack along the frame.
[0016] In some examples, the rack slides can include a series of slidingly connected rails including a first rail connected to the oven rack and a second rail connected between posts of the frame.
[0017] In some examples, the oven rack adjustment system can include a retention mechanism positioned on the frame and configured to engage a protrusion extending from a sidewall of an oven to secure the oven rack adjustment system within the oven.
[0018] According to yet another aspect of the present disclosure, an oven rack adjustment system can include a frame having first and second posts with teeth defining cutouts and a rack support securing an oven rack to the frame and including rack slides that permit telescopic movement of the oven rack. The system can include a latch having first and second pins, the first and second pins engaging the first and second posts, when a locked position, and disengaging from the first and second posts when in an unlocked position. The system can include a retention mechanism, including a catch plate defining a retention channel and a retention arm, the retention arm engaging a protrusion extending from an oven sidewall to secure the oven rack adjustment system within an oven.
[0019] In some examples, the rack slides can include a series of slidingly connected rails including a first rail connected to the oven rack and a second rail connected between the first and second posts of the frame.
[0020] In some examples, the system can include one or more linear bearings secured around one or more corresponding guide rods, the guide rods being secured adjacent the first and second posts of the frame.
[0021] In some examples, the retention mechanism can include a release mechanism having a handle, movement of the handle actuating the retention arm to move the retention arm out of engagement with the protrusion to permit removal of the oven rack adjustment system from the oven.
[0022] In some examples, the retention arm can be in the form of a leaf spring with an end abutting an edge of the protrusion when in a locked position.BRIEF DESCRIPTION OF THE DRAWINGS

[0049] The following discussion is presented to enable a person skilled in the art to make and use embodiments of the invention. Given the benefit of this disclosure, various modifications to the illustrated embodiments will be readily apparent to those skilled in the art, and the principles herein can be applied to other embodiments and applications without departing from embodiments of the invention. Thus, embodiments of the invention are not intended to be limited to embodiments shown, but are to be accorded the widest scope consistent with the principles and features disclosed herein.
[0050] The following detailed description is to be read with reference to the figures, in which like elements in different figures have like reference numerals. The figures, which are not necessarily to scale, depict selected embodiments and are not intended to limit the scope of embodiments of the invention. Skilled artisans will recognize the examples provided herein have many useful alternatives and fall within the scope of embodiments of the invention.
[0051] Before any embodiments of the invention are explained in detail, it is to be understood that the invention is not limited in its application to the details of construction and the arrangement of components set forth in the following description or illustrated in the following drawings. The invention is capable of other embodiments and of being practiced or of being carried out in various ways. Also, it is to be understood that the phraseology and terminology used herein is for the purpose of description and should not be regarded as limiting. The use of “including, ” “comprising, ” or “having” and variations thereof herein is meant to encompass the items listed thereafter and equivalents thereof as well as additional items. Unless specified or limited otherwise, the terms “mounted, ” “connected, ” “supported, ” and “coupled” and variations thereof are used broadly and encompass both direct and indirect mountings, connections, supports, and couplings. Further, “connected” and “coupled” are not restricted to physical or mechanical connections or couplings.
[0052] In some examples, an oven rack adjustment system may include a frame and an oven rack secured to the frame via a rack support. Further, in order to permit movement of the oven rack with respect to the frame, the oven rack adjustment system may an assisted system, which may reduce the overall force required to move the oven rack. For example, the oven rack adjustment system may include a roller arranged through a slot defined by the rack support and engaged with an angled guide of the frame. Further, in some examples, to permit automated or assisted movement of the oven rack, a biasing element (e.g., a spring) may be arranged between the roller and the rack support so that a biasing force is applied to the roller via the biasing element.
[0053] Further, in some examples, the oven rack system may include a latch, the latch may include one or more pins configured to engage with one or more teeth extending from the frame. In some examples, the one or more pins may be selectively engaged with the one or more teeth to define a height of the oven rack. Further, the one or more pins may be selectively engaged with the one or more teeth via movement of a handle of the latch. For example, the handle may be in a first handle position to engage the pin with the teeth (e.g., forming a locked configuration of the oven rack) . Further, the handle may be in a second handle position to disengage the pin from the teeth (e.g., forming an unlocked configuration of the oven rack) .
[0054] In some examples, the latch may further include a biasing element configured to bias the pins towards engagement with the teeth (e.g., toward the locked configuration) , so that when a user releases the handle, the latch automatically returns to the locked configuration.
[0055] In some examples, when the latch is in the unlocked configuration, the position of the rack may be adjusted. For example, when the latch is in the unlocked configuration, the force applied by the biasing element may pull the roller along the angled guide, which may drive the oven rack upwards (e.g., against gravity) . As should be appreciated, the force applied by the biasing element may be the strongest when the oven rack is lower, but may become weaker as the oven rack is raised.
[0056] In some examples, to prevent misalignment of the oven rack during movement, the rack support may include one or more alignment posts, which may engage with the frame (e.g., slide along the frame) during movement of the oven rack to mitigate misalignment of the oven rack. Further, these alignment posts may be offset (e.g., vertically offset) to mitigate binding of the oven rack during movement.
[0057] FIG. 1 shows an example of an oven rack adjustment system 100, which may provide assisted (e.g., spring assisted) adjustment of an oven rack 110. In some examples, the rack adjustment system 100 may include a frame 105 configured to support and secure the rack 110 (e.g., an oven rack) at one or more positions (e.g., heights) along the frame 105. In some examples, the rack 110 may be secured to the frame 105 via a rack support 115, which may include one or more rack slides (e.g., to permit movement of the rack transverse to the frame) . Further, in some examples, the rack adjustment system 100 may facilitate assisted adjustment of the rack 110 in the direction shown by arrow 120. For example, the rack adjustment system 100 may reduce the effective weight of the rack 110 via the use of one or more biasing elements (e.g., springs) .
[0058] In some examples, in order to permit movement of the rack 110, the rack adjustment system 100 may include a latch 125, which may selectively lock and unlock movement of the rack 110 relative to the frame 105. For example, the latch 125 may be actuated by a user when a change in position of the rack 110 is desired. Correspondingly, when the user releases the latch 125, the latch 125 may automatically engage the frame 105 to lock the rack 110 into position.
[0059] FIGS. 2 and 3 show examples of the latch 125 in a locked position 200 and an unlocked position 300, respectively. In the locked position 200, a first pin 215 (or other latching member) of the latch 125 may engage a first post 205 of the frame 105, while a second pin 220 (or other latching member) of the latch 125 may engage a second post 210 of the frame 105. In some examples, the first post 205 and the second post 210 may include one or more teeth, which may engage first and second pins 215, 220 to lock the rack 110 at a user-defined height. In some examples, the spacing between the teeth may define the adjustment increments for the rack (e.g., teeth spacing of 1 inch may equate to a 1 inch position adjustment of the rack 110) .
[0060] In some examples, to move the latch 125 between the locked position 200 and the unlocked position 300 (see, e.g., FIG. 3) , a handle 225 of the latch 125 may be actuated in the direction shown by arrow 230 (e.g., towards a crossbeam of the rack support 115) . For example, as the user moves the handle 225 in the direction shown by arrow 230, the first pin 215 and the second pin 220 may disengage from the first post 205 and the second post 210, respectively, which unlocks the rack 110 (and rack support 115) from the frame 105 and permits adjustment (e.g., vertical adjustment) of the rack 110 in the directions shown by arrow 305.
[0061] In some examples, as shown in FIG. 4, the latch 125 may include a biasing element 405 (e.g., a torsion spring) to bias the latch 125 into the locked position 200. For example, the biasing element 405 may be arranged between a crossbeam of the rack support 115 and the second pin 220 of the latch 125 so that a biasing force in the direction shown by arrow 410 is applied to the second pin 220 (e.g., to push the second pin 220 towards engagement with the second post 210) . Thus, in some examples, when a user releases the handle 225, the latch 125 may automatically return to the locked position 200 and prevent further movement of the rack 110. Correspondingly, in order to move the latch 125 into the unlocked position 300, a user may need to apply a force to the handle 225 sufficient to overcome the biasing force of the biasing element 405.
[0062] FIG. 5 illustrates an example of a force reduction assembly 500 of the rack adjustment system 100. In some examples, the force reduction assembly 500 may include a roller 505 (e.g., a bearing, wheel, etc. ) arranged within a slot 510 defined by the rack support 115. The roller 505 may be configured to ride along an angled guide 515 extending within the frame 105 during movement of the rack 110. Further, to reduce the force required to lift (e.g., move) the rack 110, a biasing element (e.g., a spring) 520 may be arranged between the roller 505 and a portion of the rack support 115, so that a biasing force is applied to the roller 505 (e.g., to bias the roller 505 in the direction shown by arrow 525) . Thus, when a user moves the latch 125 into the unlocked position 300, the biasing force applied to the roller 505 urges the roller 505 in the direction shown by arrow 525, which drives the roller 505 along the angled guide 515 to reduce the force required by a user to move the rack 110 along the frame 105 (e.g., adjust a vertical height of the rack 110 within the oven) .
[0063] In some examples, the biasing element 520 may be in the form of a spring, which a spring force of between 1 and 10 pounds. In other examples, the spring may have a spring force of about 7 pounds. As should be appreciated, while only a single roller 505 and biasing element 520 are shown in FIG. 5 it is envisioned that a pair of rollers 505 and biasing elements 520 may be used (e.g., one per each side of the rack 110) .
[0064] FIGS. 6-8 show the rack 110 arranged at various positions (e.g., heights) along the frame 105. For example, FIG. 6 shows the rack 110 at about a bottom of the frame 105. In some examples, when the rack 110 is at a bottom section of the frame 105, the biasing force applied by the biasing element 520 may be the largest, which may, when the assisted positioning system 130 is in the unlocked position 300, move the roller 505 in the direction shown by arrow 605, along the guide 515. As a result, the rack 110 may move in the direction shown by arrow 610, without requiring the user to apply force to the rack 110. Put differently, when the rack 110 is arranged at about a bottom of the frame 105, the rack 110 may move in the direction shown by arrow 610 automatically, when the assisted positioning system 130 is in the unlocked position 300.
[0065] In some examples, once the rack 110 reaches about a midpoint of the frame 105 (e.g., as shown in FIG. 7) , the biasing force applied by the biasing element 520 may be reduced, which may cause the rack 110 to hover (e.g., settle) at about the midpoint of the frame 105. Put differently, at about the midpoint of the frame 105, the biasing force applied by the biasing element 520 and the opposing force of gravity may be about equal as represented by arrows 705. Thus, as shown in FIG. 8, movement of the rack 110 above the midpoint of the frame 105 may require the user to apply a force to the rack 110 in the direction shown by arrow 805. However, due to the biasing force applied to the roller 505 by the biasing element 520, the force required from a user to move the rack 110 above the midpoint of the frame 105 may be reduced vs. configurations without the force reduction assembly 500.
[0066] With reference to FIG. 9, in some examples, to mitigate misalignment of the rack 110 (e.g., during movement of the rack 110 as shown by arrow 905) , the rack support 115 may include one or more alignment posts 910, 915. For example, a first alignment post 910 may extend from a first end of the rack support 115 and contact a face of the first post 205. Correspondingly second alignment post 915 may extend from a second, opposite end of the rack support and contact a face of the second post 210. Thus, as the rack 110 moves in the directions shown by arrows 905, the first and second alignment posts 910, 915 may ride along the respective faces of the first and second posts 205, 210 to maintain alignment of the rack 110.
[0067] In some examples, to mitigate binding of the rack 110 during movement as shown by arrows 905, the first and second alignment posts 910, 915 may be vertically offset relative to each other. For example, the second alignment post 915 may be positioned higher (e.g., vertically higher) than the first alignment post 910. Further, in some examples, the first and second alignment posts 910, 915 may be in the form of metallic posts with substantially-circular cross-sections. However, in other examples, the alignment posts 910, 915 may be in the form of rollers, bearings, wheels, etc.
[0068] FIGS. 10 and 11 show an example process for installing the rack 110 within the frame 105. For example, to install the rack 110 into the frame 105, a user may place the second alignment post 915 into contact with the face of the second post 210. Following this, the user may pivot (e.g., rotate) the rack 110 about the alignment post 915 so that the roller 505 passes through a cutout 1010 defined in a crossmember 1005 (e.g., extending between the first and second posts 205, 210) of the frame 105. Once the roller 505 is arranged within the cutout 1010, the alignment post 910 may contact the face of the first post 205, so that the frame 105 is captured (e.g., arranged) between the first alignment post 910 and the second alignment post 915 of the rack support 115, with the roller 505 contacting the angled guide 515. Following this, the user may actuate the handle 225 to move the rack 110 to the desired position (e.g., height) within the oven.
[0069] As should be appreciated, in some examples, a user may wish to have multiple racks 110 within the oven. Thus, the user may continue to insert a second, third, fourth, or more racks 110 as described above. Correspondingly, to remove a rack 110, the user may actuate the handle 225 to unlock movement of the rack 110 and then slide the rack 110 out of the crossmember 1005.
[0070] While the oven rack adjustment system 100 described above has been illustrated with only a single side of the frame 105, it should be appreciated that the frame 105 may include a second side, which may be a mirror-image of the side described above and represented in the FIGS. For example, the oven rack adjustment system 100 may include a second side with a frame, pins, rollers, springs, alignment posts, angled guides, etc., as described above.
[0071] FIGS. 12-17 illustrate another example of an oven rack adjustment system 1200. As will be recognized, the oven rack adjustment system 1200 shares a number of components in common with and operates in a similar fashion to the examples illustrated and described previously (e.g., the oven rack adjustment system 100) . For the sake of brevity, these common features will not be again described below in detail. Rather, previous discussion of commonly named or numbered features, unless otherwise indicated, also applies to example configurations of the oven rack adjustment system 1200.
[0072] In some examples, the oven rack adjustment system 1200 may include one or more rack slides 1205, which may form a portion of the rack support 115. In some examples, the rack slides 1205 may permit telescopic movement of the rack 110 in the directions shown by arrow 1305 of FIG. 13. Thus, a user may be able to slide the rack 110 transverse to the frame 105 to permit easy access to the rack (e.g., to retrieve items from the rack) or to return the rack within the frame 105 (e.g., during insertion or removal of the rack 110) . In some examples, the rack slides 1205 may include a series of slidingly connected rails. For example, the rack slides 1205 may include a first (e.g., inner) rail connected to the rack 110, a second, (e.g., outer) rail connected between the first post 205 and the second post 210 of the frame, and a third, (e.g., intermediate) rail connected between the first rail and the second rail. In some examples the slides 1205 may be in the form of friction-type slides, without bearings, or bearing-type slides including one or more bearings arranged in a bearing retainer between each of the rails.
[0073] In some examples, to permit movement of the rack 110 in the directions shown by arrows 1515 of FIG. 15, without binding or catching, the oven rack adjustment system 1200 may include one or more linear bearings 1505. In one particular examples, the oven rack adjustment system 1200 may include four (4) linear bearings 1505 arranged at each corner of the rack 110. In some examples, each of the linear bearings 1505 may be secured around (e.g., circumferentially around) and move along a corresponding guide rod 1510. For example, as the user moves the rack 110 in the directions shown by arrows 1515, the bearings 1505 may slide along the guide rods 1510 to maintain alignment of the rack 110 during movement, without binding or catching.
[0074] Referring particularly to FIG. 16, in some examples, the guide rods 1510 may be secured adjacent the posts (e.g., each of posts 205, 210) of the frame, with the rack slides 1205 secured to the bearings 1505 via a bracket 1605. Thus, the rack 110 is secured to the bearings 1505 via the rack slides 1205 (e.g., via the second rail of the rack slides, which is in turn connected to the bearing via the bracket 1605) . As a result, movement of the rack 110 translates to movement of the bearing 1505 along the guide rod and vice versa.
[0075] With reference to FIG. 17, the latch 125 may include a biasing element 1705 (e.g., a spring) to bias the latch 125 into the locked position 200. For example, the biasing element 1705 may be secured to (e.g., around) a crossbeam 1710 or other portion of the rack support 115, with a first end of the biasing element 1705 anchored to the rack slides 1205, and a second end secured to the second pin 220 of the latch 125. As a result, a biasing force may be applied to the second pin 220 (e.g., to push the second pin 220 towards engagement with the second post 210) . Thus, in some examples, when a user releases the handle 225 (e.g., after moving the latch 125 into the unlocked position 300 of FIG. 3) , the latch 125 may automatically return to the locked position 200 and prevent further movement of the rack 110. Correspondingly, in order to move the latch 125 into the unlocked position 300, a user may need to apply a force to the handle 225 sufficient to overcome the biasing force of the biasing element 1705.
[0076] FIGS. 18-25 illustrate another example of an oven rack adjustment system 1800. As will be recognized, the oven rack adjustment system 1800 shares a number of components in common with and operates in a similar fashion to the examples illustrated and described previously (e.g., the oven rack adjustment systems 100, 1200) . For the sake of brevity, these common features will not be again described below in detail. Rather, previous discussion of commonly named or numbered features, unless otherwise indicated, also applies to example configurations of the oven rack adjustment system 1800.
[0077] In some examples, the oven rack adjustment system 1800 (and the oven rack adjustment systems 100, 1200) can be positioned within an oven 1820. In some examples, the oven 1820 may include one or more sidewalls 1805 the define one or more rack guides 1810 extending from an interior of the sidewalls 1805. Traditionally, these rack guide 1810 were used to permit a user to insert and remove traditional oven racks (e.g., an oven rack 1815) from within the oven 1820. In some examples, to permit user adjustability, the oven rack adjustment system 1800 may be used along with a traditional oven rack 1815 positioned on the one or more rack guides 1810.
[0078] In some examples, as has been described above, the oven rack adjustment system 1800 may permit a user to adjust the height of the oven rack 110 within the oven 1820. For example, the oven rack may be moved and set at a number of different heights between a first (e.g., lowermost) position 1905 as shown in FIG. 19 and a second (e.g., uppermost) position 1825 as shown in FIG. 18.
[0079] In some examples, as shown in FIG. 25, a spacing 2515 between adjacent cutouts formed in the frame 105 (e.g., formed in the first and second posts 205, 210 of the frame 105) may define the different adjustment heights of the rack 110. In some examples, as mentioned above, one or more teeth 2510 may define the cutouts 2505 and provide a contact surface for the oven rack 110 to rest on when at a user-desired height. In some examples, the spacing 2515 may correspond to a spacing between the rack guides 1810 extending from the sidewalls of the oven 1820. However, in other examples, the spacing 2515 may be larger or smaller than the spacing between the rack guides 1810, to permit a user to have more adjustability versus with traditional oven rack systems.
[0080] In some examples, to install the oven rack adjustment system 1800 into the oven 1820, the user may align the oven rack adjustment system 1800 with an opening 2005 defined by the sidewalls 1805 and a base 2015 of the oven 1820. In some examples, the user may slide the oven rack adjustment system 1800 into the oven 1820 with the second posts 210 entering the opening first, and with one or more bottom posts 2020 of the oven rack adjustment system 1800 contacting the base 2015 of the oven 1820. Following this, the user may slide (e.g., push) the oven rack adjustment system 1800 into the opening 2005 of the oven, with the second posts 210 approaching a backwall 2010 of the oven. In some examples, the user may continue to slide the oven rack adjustment system 1800 into the oven until one or more retention mechanisms 2025 positioned on top posts 2030 of the oven rack adjustment system 1800 engage protrusions extending from the sidewalls 1805 of the oven 1820. In some examples, once the retention mechanisms 2025 engage the protrusion of the oven, the oven rack adjustment system 1800 may be secured (e.g., locked) within the opening 2005 of the oven 1820 until released by a user.
[0081] In some examples, the retention mechanism 2025 (see, e.g., FIGS. 21-24) may be configured to prevent a user from removing the oven rack adjustment system 1800 from within the oven (e.g., in the direction shown by arrow 2105) . For example, the retention mechanism 2025 may include a catch plate 2115 that receives and secures a protrusion 2125 extending from an interior 2130 of the sidewalls 1805 of the oven. In some examples, the catch plate 2115 may be secured to the frame 105 of the adjustment system 1800 and aligned with the protrusion 2125 so that as the user slides the adjustment system 1800 into the oven (e.g., in the direction shown by arrow 2205) , the protrusion 2125 automatically engages the catch plate 2115.
[0082] In some examples, in order to receive and retain the protrusion 2125, the catch plate 2115 may define a retention channel 2210. The retention channel 2210 may be configured to receive and retain the protrusion 2125. In some examples, to guide the protrusion 2125 into a retention channel, the retention channel may define one or more chamfered edges 2305. In some examples, a retention arm 2120 (e.g., a biased retention arm) may be secured to the frame 105 and arranged to block (e.g., contact) the protrusion 2125 to prevent the protrusion 2125 from leaving the retention channel 2210. As a result, the adjustment system 1800 may be secured within the oven. Further, in some examples, to permit a user to release the retention mechanism 2025 (and corresponding permit removal of the adjustment system 1800) the retention mechanism 2025 may include a release mechanism 2110. In some examples, the release mechanism 2110 may permit a user to actuate the release mechanism in order to move (e.g., actuate) the retention arm 2120. In some examples, actuation of the retention arm 2120 may move the retention arm out of the path of the protrusion 2125 and permit the protrusion 2125 to slide out of the retention channel 2210.
[0083] With particular reference to FIGS. 23 and 24, the retention arm 2120 may be in the form of a biased retention arm (e.g., a leaf spring, spring steel, or other biased material) that is configured to block egress of the protrusion 2125 from the retention channel 2210. For example, when the retention arm 2120 is in a locked position, an end 2310 of the retention arm 2120 may abut an edge 2430 of the protrusion 2125 to mitigate removal of the protrusion from the retention channel 2210. In some examples, the protrusion 2125 may be shaped with the edge 2430 forming a portion with a larger diameter than a center portion of the protrusion 2125, and with the center portion being arranged within the retention channel, while the edge contacts the end of the retention arm.
[0084] In some examples, if a user desires to unlock the retention arm (e.g., to remove the oven rack adjustment system 1800) the user may grasp a handle 2405 of the release mechanism 2110 and apply a force in the direction shown by arrow 2410, which may rotate the release mechanism 2110 about a fastener 2435 (e.g., securing the release mechanism to the frame 105, forming a pivot axis) . In some examples, as the release mechanism 2110 rotates, a tab 2415 of the release mechanism may move the end 2310 of the retention arm 2120 in the direction shown by arrow 2425 (e.g., out of abutment with the protrusion 2125) . In some examples, to facilitate movement of the retention arm 2120, the tab 2415 may be arranged within a pocket 2420 formed adjacent the end of the retention arm. Following this, the user may grasp and slide the oven rack adjustment system 1800 out of the oven 1820. As should be appreciated, the oven rack adjustment system 1800 may include one, two, or more retention mechanisms arranged on various components of the frame 105 or other areas of the oven rack adjustment system.

[0107] Also as used herein, unless otherwise limited or defined, “or” indicates a non-exclusive list of components or operations that can be present in any variety of combinations, rather than an exclusive list of components that can be present only as alternatives to each other. For example, a list of “A, B, or C” indicates options of: A; B; C; A and B; A and C; B and C; and A, B, and C. Correspondingly, the term “or” as used herein is intended to indicate exclusive alternatives only when preceded by terms of exclusivity, such as “either, ” “one of, ” “only one of, ” or “exactly one of. ” For example, a list of “one of A, B, or C” indicates options of: A, but not B and C; B, but not A and C; and C, but not A and B. A list preceded by “one or more” (and variations thereon) and including “or” to separate listed elements indicates options of one or more of any or all of the listed elements. For example, the phrases “one or more of A, B, or C” and “at least one of A, B, or C” indicate options of: one or more A; one or more B; one or more C; one or more A and one or more B; one or more B and one or more C; one or more A and one or more C; and one or more of A, one or more of B, and one or more of C. Similarly, a list preceded by “a plurality of” (and variations thereon) and including “or” to separate listed elements indicates options of multiple instances of any or all of the listed elements. For example, the phrases “a plurality of A, B, or C” and “two or more of A, B, or C” indicate options of: A and B; B and C; A and C; and A, B, and C.
[0108] As used herein, unless otherwise defined or limited, directional terms are used for convenience of reference for discussion of particular figures or examples. For example, references to downward (or other) directions or top (or other) positions may be used to discuss aspects of a particular example or figure, but do not necessarily require similar orientation or geometry in all installations or configurations.
[0109] Also as used herein, unless otherwise limited or defined, “substantially parallel” indicates a direction that is within ± 12 degrees of a reference direction (e.g., within ± 6 degrees) , inclusive.
[0110] Also as used herein, unless otherwise limited or defined, “substantially perpendicular” indicates a direction that is within ± 12 degrees of perpendicular a reference direction (e.g., within ± 6 degrees) , inclusive.
[0111] Also as used herein, unless otherwise limited or defined, “integral” and derivatives thereof (e.g., “integrally” ) describe elements that are manufactured as a single piece without fasteners, adhesive, or the like to secure separate components together. For example, an element stamped, cast, or otherwise molded as a single-piece component from a single piece of sheet metal or using a single mold, without rivets, screws, or adhesive to hold separately formed pieces together is an integral (and integrally formed) element. In contrast, an element formed from multiple pieces that are separately formed initially then later connected together, is not an integral (or integrally formed) element.
[0112] Additionally, unless otherwise specified or limited, the terms “about” and “approximately, ” as used herein with respect to a reference value, refer to variations from the reference value of ± 15%or less, inclusive of the endpoints of the range. Similarly, the term “substantially equal” (and the like) as used herein with respect to a reference value refers to variations from the reference value of less than ± 10%, inclusive. Where specified, “substantially” can indicate in particular a variation in one numerical direction relative to a reference value. For example, “substantially less” than a reference value (and the like) indicates a value that is reduced from the reference value by 10%or more, and “substantially more” than a reference value (and the like) indicates a value that is increased from the reference value by 10%or more.
[0113] Also as used herein, unless otherwise limited or specified, “substantially identical” refers to two or more components or systems that are manufactured or used according to the same process and specification, with variation between the components or systems that are within the limitations of acceptable tolerances for the relevant process and specification. For example, two components can be considered to be substantially identical if the components are manufactured according to the same standardized manufacturing steps, with the same materials, and within the same acceptable dimensional tolerances (e.g., as specified for a particular process or product) .
[0114] Unless otherwise specifically indicated, ordinal numbers are used herein for convenience of reference, based generally on the order in which particular components are presented in the relevant part of the disclosure. In this regard, for example, designations such as “first, ” “second, ” etc., generally indicate only the order in which a thus-labeled component is introduced for discussion and generally do not indicate or require a particular spatial, functional, temporal, or structural primacy or order.
