DETAILED DESCRIPTION
Example embodiments will now be described more fully with reference to the accompanying drawings. Example embodiments are provided so that this disclosure will be thorough, and will fully convey the scope to those who are skilled in the art. Numerous specific details are set forth such as examples of specific components, devices, and methods, to provide a thorough understanding of embodiments of the present disclosure. It will be apparent to those skilled in the art that specific details need not be employed, that example embodiments may be embodied in many different forms and that neither should be construed to limit the scope of the disclosure. In some example embodiments, well-known processes, well-known device structures, and well known technologies are not described in detail.
The terminology used herein is for the purpose of describing particular example embodiments only and is not intended to be limiting. As used herein, the singular forms “a,” “an,” and “the” may be intended to include the plural forms as well, unless the context clearly indicates otherwise. The terms “comprises,” “comprising,” “including,” and “having,” are inclusive and therefore specify the presence of moded features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof. The method steps, processes, and operations described herein are not to be construed as necessarily requiring their performance in the particular order discussed or illustrated, unless specifically identified as an order of performance. It is also to be understood that additional or alternative steps may be employed.
When an element or sheet is referred to as being “on,” “engaged to,” “connected to,” or “coupled to” another element or sheet, it may be directly on, engaged, connected or coupled to the other element or sheet, or intervening elements or sheets may be present. In contrast, when an element is referred to as being “directly on,” “directly engaged to,” “directly connected to,” or “directly coupled to” another element or sheet, there may be no intervening elements or sheets present. Other words used to describe the relationship between elements should be interpreted in a like fashion (e.g., “between” versus “directly between,” “adjacent” versus “directly adjacent,” etc.). As used herein, the term “and/or” includes any and all combinations of one or more of the associated listed items.
Although the terms first, second, third, etc. may be used herein to describe various elements, components, regions, sheets and/or sections, these elements, components, regions, sheets and/or sections should not be limited by these terms. These terms may be only used to distinguish one element, component, region, sheet or section from another region, sheet or section. Terms such as “first,” “second,” and other numerical terms when used herein do not imply a sequence or order unless clearly indicated by the context. Thus, a first element, component, region, sheet or section discussed below could be termed a second element, component, region, sheet or section without departing from the teachings of the example embodiments.
Spatially relative terms, such as “inner,” “outer,” “beneath,” “below,” “lower,” “above,” “upper,” and the like, may be used herein for ease of description to describe one element or feature's relationship to another element(s) or feature(s) as illustrated in the figures. Spatially relative terms may be intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, elements described as “below” or “beneath” other elements or features would then be oriented “above” the other elements or features. Thus, the example term “below” can encompass both an orientation of above and below. The device may be otherwise oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.
With reference to FIGS. 1A-8A and 1B-8B, an exemplary cable guide is shown generally at 10. Furthermore, an exemplary cable engagement device is shown generally at 75 in FIGS. 9-11. Yet even further, a cable tensioning device 85 including a cable 87 having a length L87 is also shown in FIGS. 12-13 and 15.
As seen in FIG. 20, two or more cable guides 10, two or more cable engagement devices 75 and the cable tensioning device 85 cooperate to define an implement interlock system 100 for interlocking two or more implements D1-D4 (e.g., two or more moveable components of an article of furniture, such as, for example, drawers) that are movably-secured to an implement housing H (e.g., a stationary component of an article of furniture such as, for example, a dresser cabinet defining a cavity for storing the two or more drawers D1-D4). With reference to FIGS. 25A-25D, the implement interlock system 100 permits a first drawer (see, e.g., D2 in FIGS. 25A-25D) of the two or more drawers D1-D4 to transition from a nested orientation (see, e.g., FIG. 25A) within the dresser cabinet H to a fully slid outwardly orientation (see, e.g., FIG. 25B) outside of the dresser cabinet H while also preventing a second drawer (see, e.g., D3 in FIGS. 25A-25D) of the two or more drawers D1-D4 to also be arranged in a fully slid outwardly orientation outside of the dresser cabinet H. Accordingly, if a user attempts to move the second drawer D3 of the two or more drawers D1-D4 from the nested orientation (see, e.g., FIG. 25B) within the dresser cabinet H toward a fully slid outwardly orientation (see, e.g., FIG. 25D) outside of the dresser cabinet H while the first drawer D2 is already arranged in the fully slid outwardly orientation outside of the dresser cabinet H, this movement of the second drawer D3 either will be prevented or retarded, or the implement interlock system 100 will automatically retract (see, e.g., FIGS. 25C-25D) the previously extended first drawer D2 of the two or more drawers D1-D4 from the fully slid outwardly orientation (see, e.g., FIG. 25B) outside of the dresser cabinet H back to the nested orientation (see, e.g., FIG. 25D) within the dresser cabinet H. If the movement of drawer D3 is prevented, then the user must move the first drawer D2 to the nested orientation prior to transitioning the second drawer D3 toward a fully slid outwardly orientation.
Referring to FIGS. 1A-8B, the cable guide 10 is now described. As seen in FIG. 1A, the cable guide 10 includes a body 12 having a central body portion 14, an upper body portion 16 and a lower body portion 18.

The central body portion 14 is further defined by a length L14 (see, e.g., FIGS. 2A, 8A-8B) extending between an upper end 14U of central body portion 14 and a lower end 14L of central body portion 14. The central body portion 14 is further defined by a width W14a, W14b (see, e.g., FIGS. 2A, 7A, 7A′) extending between a first side surface 14S1 of central body portion 14 and a second side surface 14S2 of central body portion 14.
Referring to FIG. 1A, an attachment hardware bore 20 may extend through the thickness T14 of the central body portion 14. A fastener F (see, e.g., FIGS. 16-17) may be arranged within the attachment hardware bore 20 for attaching the cable guide 10 to a panel P (see, e.g., FIGS. 16-17) of, for example, the plurality of panels defining the dresser cabinet H. As seen in FIGS. 16-17, the fastener F may pass through the attachment hardware bore 20 and into a fastener bore B formed by a panel P (see, e.g., FIGS. 16-17) of, for example, the plurality of panels defining the dresser cabinet H for attaching the cable guide 10 to the panel P.
As seen in FIG. 1A, one or more of a first attachment projection 22a and a second attachment projection 22b may extend away from the rear surface 14R of the central body portion 14. With reference to FIGS. 1A and 8A-8B, the first attachment projection 22a extends away from the rear surface 14R of the central body portion 14 near the upper end 14U of the central body portion 14. Referring to FIGS. 1A and 8A-8B, the second attachment projection 22b extends away from the rear surface 14R of the central body portion 14 near the lower end 14L of the central body portion 14. Each of the first attachment projection 22a and the second attachment projection 22b may be arranged within corresponding bores B (see, e.g., FIGS. 16-17) formed by a panel P (see, e.g., FIGS. 16-17) of, for example, the plurality of panels defining the dresser cabinet H for attaching the cable guide 10 to the panel P.

Referring to FIGS. 1A, 2A, 3A, 4A, 5A, 6A, 7A and 8A, the cable guide 10 is shown arranged in a first orientation. The first orientation may be alternatively referred to as an “open orientation” whereby both of the upper cable-retaining body 52 and the lower cable-retaining body 54 that integrally-extend away from the body 12 are not removably-secured to the body 12. Conversely, as seen in 1B, 2B, 3B, 4B, 5B, 6B, 7B and 8B, the cable guide 10 is shown arranged in a second orientation. The second orientation may be alternatively referred to as a “closed orientation” whereby both of the upper cable-retaining body 52 and the lower cable-retaining body 54 that integrally-extend away from the body 12 are removably-secured to the body 12. The purpose of removably-securing the upper cable-retaining body 52 and the lower cable-retaining body 54 to the body 12 is described in greater detail in the following disclosure at FIGS. 17-19.
Referring to FIGS. 9-11, an exemplary cable engagement device 75 is now described. The cable engagement device 75 includes a base portion 77 and a hook portion 79.
The base portion 77 is defined by a thickness T77 (see, e.g., FIG. 11). An attachment hardware bore 81 may extend through the thickness T77 of the base portion 77.
The hook portion 79 is arranged at an angle θ79 relative the base portion 77. The angle θ79 may be approximately equal to 45°. With reference to FIGS. 10-11, the hook portion 79 further includes a ramp surface 831 and a cable-pulling surface 832. With reference to FIG. 9, the base portion 77 may also define a locating ledge 833.
Referring to FIGS. 12-13, an exemplary cable tensioning device 85 including the cable 87 is now described. The cable tensioning device 85 includes a casing 89 having a base portion 91 and cable-stowing housing 93. The base portion 91 is a substantially planar body defined by a thickness T91 (see, e.g., FIG. 12). One or more attachment hardware bores 95 may extend through the thickness T91 of the base portion 91.
As seen in FIG. 13, a cable tensioner 97 (e.g. a spring) may be disposed within the cable-stowing housing 93 for biasing the cable 87 within the cable-stowing housing 93 in a wound orientation. Accordingly, when a force that overcomes the bias imparted by the cable tensioner 97 is applied to the cable 87, a length of the cable 87 is drawn out of the cable-stowing housing 93. After the force is no longer applied to the cable, the bias imparted by the cable tensioner 97 reels the length of the cable 87 back into the cable-stowing housing 93. In order to access the cable 87 for imparting the bias-overcoming force to the cable 87 as described above, at least a portion of the length of the cable 87 extending from a distal end 87D of the cable 87 remains outside of the cable-stowing housing 93.
Referring to FIGS. 14-19, a method of interfacing portions (e.g., the cable tensioning device 85 including the cable 87 and at least one cable guide 10) of the implement interlock system 100 with one another is now described. Although a portion of a panel P of, for example, a plurality of panels defining an article of furniture such as a dresser cabinet H is also shown in FIGS. 14-19, the panel P is not required for joining or interfacing portions of the implement interlock system 100 as shown and described at FIGS. 14-19. Therefore, the panel P may be considered to be an environmental or optional component and should not be construed as a feature or structure of the implement interlock system 100.
As seen in FIGS. 14-15, the cable tensioning device 85 may be secured to the panel P. In an example, one or more fasteners F may be passed through the one or more attachment hardware bores 95 extending through the thickness T91 of the base portion 91 of the cable tensioning device 85. The fasteners F may then be passed into one or more corresponding fastener bores B formed by a panel P for securing the cable tensioning device 85 to the panel P.
With reference to FIG. 15, after securing the cable tensioning device 85 to the panel P, the distal end 87D of the cable 87 may be pulled with a force according to the direction of the arrow X. Pulling the distal end 87D of the cable 87 with the force X results in at least a portion L87-P of the length L87 of the cable 87 being drawn out of the cable-stowing housing 93; the length L87 of the cable 87 extends between the distal end 87D of the cable 87 and the proximal end 87P of the cable 87.
Referring to FIGS. 16-17, the cable guide 10 may be secured to the panel P by passing a fastener F through the attachment hardware bore 20 and into a corresponding fastener bore B formed by the panel P. Alternatively, or, in addition to passing the fastener F through the attachment hardware bore 20 and into a corresponding fastener bore B formed by the panel P, each of the first attachment projection 22a and the second attachment projection 22b may be arranged within corresponding bores B formed by the panel P. As seen in FIG. 17, before and just after the cable guide 10 is secured to the panel P, the cable guide 10 is arranged in the first, “open orientation.”
Referring to FIGS. 17-19, portions (e.g., the cable 87 of the cable tensioning device 85 and at least one cable guide 10) of the implement interlock system 100 are interfaced with one another. Firstly, as seen in FIG. 17, while the cable guide 10 is arranged in the first, “open orientation,” the portion L87-P of the length L87 of the cable 87 is aligned with: (1) the cable-receiving passageway or slot 38a formed by the end portion 24a of the upper body portion 16 of the body 12 of the cable guide 10; and (2) the cable-receiving passageway or slot 38b formed by the end portion 24b of the lower body portion 18 of the body 12 of the cable guide 10. As seen in FIG. 18, the portion L87-P of the length L87 of the cable 87 is disposed within each of the cable-receiving passageway or slots 38a, 38b while the cable guide 10 remains in the first, “open orientation.” Then, as seen in FIG. 19, while the portion L87-P of the length L87 of the cable 87 is disposed within each of the cable-receiving passageway or slots 38a, 38b, the cable guide 10 is transitioned from the first, “open orientation” to the second, “closed orientation” by respectively folding both of the upper cable-retaining body 52 and the lower cable-retaining body 54 over the end portions 24a, 24b of body 12 in order to retain the portion L87-P of the length L87 of the cable 87 within the cable-receiving passageway or slots 38a, 38b formed by the cable guide 10.
Referring to FIG. 20, the methodology described in FIGS. 16-19 may be repeated several times for securing two or more cable guides 10 to the panel P, which, in an example, may be an article of furniture such as a dresser cabinet H, such that the two or more cable guides 10 are arranged in the second, “closed orientation” about a plurality of locations along the portion L87-P of the length L87 of the cable 87. Furthermore, as seen in FIG. 20 as an example, the cable tensioning device 85 (including the proximal end 87P of the cable 87) may be secured near an upper end of the panel P, and, the distal end 87D of the cable 87 may be secured near a lower end of the panel P. Although the portion L87-P of the length L87 of the cable 87 is shown at FIG. 20, an additional length of the portion L87-P of the length L87 of the cable 87 is contained within the cable-stowing housing 93 in a wound orientation. As will be described in the following disclosure, the additional length of the portion L87-P of the length L87 of the cable 87 may be drawn out of the cable-stowing housing 93 in response to movement of one or more of the implements/drawers D1-D4.
Referring to FIGS. 20-22, a method of interfacing at least one cable engagement device 75 in the implement interlock system 100 is now described. Firstly, as seen in FIG. 21′, the locating ledge 833 of the cable engagement device 75 may be disposed upon an upper surface of an implement D2; as described above, the implement D2 may be a moveable component (e.g., a drawer) of an article of furniture H. Thereafter, a fastener F may be passed through the hardware bore 81 extending through the base portion 77 of the cable engagement device 75 for securing the cable engagement device 75 to the drawer D2. As seen in FIG. 21′, after attaching the cable engagement device 75 to the drawer D2, and, upon slidably-disposing the drawer D2, within the dresser cabinet H, the hook portion 79 of the cable engagement device 75 may be arranged for movement between the end portions 24a, 24b of body 12 of the cable guide 10 such that the hook portion 79 of the cable engagement device 75 may be subsequently interfaced with some of the portion L87-P of the length L87 of the cable 87 that is secured by the cable guide 10 adjacent central body portion 14 of the cable guide 10.
Referring to FIG. 21, all of the drawers D1-D4 are shown slidably-joined to the dresser cabinet H. Slidability of the drawers D1-D4 relative to the dresser cabinet H may be achieved by a track system T formed from a first track member TD cooperating with a second track member TH. Each drawer D1-D4 may include a pair of the first track members TD such that opposite outer side surfaces of each drawer D1-D4 includes one first track member TD of the pair of first track members TD. The dresser cabinet H includes a plurality of pairs of second track members TH arranged on opposite inner side surfaces of the dresser cabinet H that receive each pair of first track members TD associated with each drawer D1-D4.
As seen in FIGS. 24B-24C, each first track member TD includes a wheel TD-W that is slidably-disposed within a channel formed by a C-shaped body of the second track member TH. As shown in FIGS. 21, 21″, 22, 22″ and 24A-24C, in some implementations, at least one second track member TH of each pair of second track members TH attached to the dresser cabinet H forms a cable-receiving passage TH-P that is sized to permit the cable 87 to pass there-through. With reference to FIGS. 24A-24C, as a result of arranging the cable 87 within the cable-receiving passage TH-P, movement of the cable 87 is permitted through the cable-receiving passage TH-P. Although all of the drawers D1-D4 are shown in FIG. 21 being slidably-joined to the dresser cabinet H, all of the drawers D1-D4 are not yet shown in a selectively-attached state with respect to the portions (e.g., the cable 87 of the cable tensioning device 85 and two, or more cable guides 10) of the implement interlock system 100.
In an example, as seen in FIGS. 21 and 21′, the hook portion 79 of the cable engagement device 75 has not yet been advanced according to the direction of arrow Y past a portion of the cable 87 extending between the end portions 24a, 24b of body 12 of the cable guide 10. As seen in FIGS. 22 and 22′, after advancing the drawer D2 further in the direction of arrow Y, the ramp surface 831 of the hook portion 79 engages the cable 87 such that the cable 87 subsequently slides over the hook portion 79 whereby the hook portion 79 is arranged past the cable 87.
Referring to FIGS. 22-22′ and 23-23′, the drawer D2 may then be slid in a direction according to arrow Y′, which is opposite the direction of arrow Y. Referring to FIGS. 23 and 23′, the movement of drawer D2 according to arrow Y′ results in the cable-pulling surface 832 of the hook portion 79 engaging and pulling the portion of the cable 87 extending between the end portions 24a, 24b of body 12 of the cable guide 10. Furthermore, the movement of drawer D2 according to arrow Y′ results in the cable-pulling surface 832 of the hook portion 79 applying a cable-pulling force X to the cable 87, thereby drawing out an additional amount of the portion L87-P of the length L87 of the cable 87 that is stored within the cable-stowing housing 93 in a wound orientation. Yet even further, after the cable-pulling surface 832 applies the cable-pulling force X to the cable 87, the cable 87 is permitted to move within the cable-receiving passageway or slots 38a, 38b and against any of the curved or arcuate inner surfaces 40a/40b, 46a/46b of the first side portion 28a/28b or second side portion 30a/30b.
Referring to FIGS. 25A-25D, a method for operating the implement interlock system 100 is described. As seen in FIG. 25A, all of the drawers D1-D4 are arranged in a selectively-attached state with respect to the portions of the implement interlock system 100 such that the cable-pulling surface 832 of the hook portion 79 may apply a cable-pulling force X to the cable 87 when any of the drawers are moved according to the direction of arrow Y′.
In an example, as seen in FIGS. 25A-25B, a user may wish to slide, according to the direction of arrow Y′, the drawer D2 outwardly from the dresser cabinet H while the remaining drawers D1, D3, D4 remain nested within the dresser cabinet H. Accordingly, the drawer D2 is slid outwardly Y′ from the dresser cabinet H and the cable-pulling surface 832 of the hook portion 79 of the drawer D2 applies a cable-pulling force X to the cable 87. Furthermore, with reference to FIG. 25B, the drawer D2 may be said to be fully slid outwardly in the direction of arrow Y′ from the dresser cabinet H, when a remaining amount of the portion L87-P of the length L87 of the cable 87 that was stored within the cable-stowing housing 93 is reeled out of the cable-stowing housing 93.
With reference to FIGS. 25B-25C, after fully sliding Y′ the drawer D2 outwardly from the dresser cabinet H, a user may attempt to slide Y′ one of the nested drawers D1, D3, D4 outwardly from a stowed orientation within the dresser cabinet H. Because all of the cable 87 had been reeled out of the cable-stowing housing 93 (as described above in response to fully extending Y′ the drawer D2), any outward movement Y′ of another the drawer D1, D3, D4 from the dresser cabinet H either will be prevented, retarded, or will cause the cable 87 to apply a pulling force according to the direction of arrow Y to the hook portion 79 of the fully extended drawer D2 in order to thereby automatically withdraw or retract the fully-extended drawer D2 back to a nest orientation within the dresser cabinet H. Therefore, as seen in FIGS. 25B-25D, movement of another drawer (e.g., drawer D3) from a nested orientation (see, e.g., FIG. 25B) within the dresser cabinet H to a fully extended orientation outside of the dresser cabinet H (see, e.g., FIG. 25D), may result in the drawer D2 being automatically retracted within the dresser cabinet H. Furthermore, when the user manually closes one or more of the extended drawers D1, D2, D3, D4 the cable tensioner 97 of the cable tensioning device 85 automatically retracts the reeled-out portion L87-P of the length L87 of the cable 87 that had been stored within the cable-stowing housing 93 prior to extending one or more drawers D1, D2, D3, D4 outside of the dresser cabinet H.
In another aspect of the implement interlock system 100, a user may selectively remove one or more of the drawers D1-D4 from the dresser cabinet H such that the drawers D1-D4 are not permanently attached to the dresser cabinet H by way of the arrangement of the cable guides 10 and cable 87. For example, as seen in FIG. 23′, a user may engage his/her finger with the cable 87 and move the cable 87 from the cable-pulling surface 832 in order to disconnect the cable 87 from the hook portion 79 of the cable engagement device 75 and thereby return the orientation of the cable 87 and the cable engagement device 75 back to the orientation shown at FIG. 21′. With the cable 87 no longer hooked about the hook portion 79 of the cable engagement device 75, the user may remove a corresponding “un-hooked” drawer D1-D4 from the dresser cabinet H.
With reference to FIG. 20, although the cable guides 10, cable engagement devices 75 and cable tensioning device 85 are shown fixed to various locations of the dresser cabinet H and drawers D1-D4, the locations of the cable guides 10, cable engagement devices 75 and cable tensioning device 85 including the cable 87 are not limited to what is shown at FIG. 20. For example, the cable guides 10, cable engagement devices 75 and cable tensioning device 85, collectively, may be positioned at the front, back, left side or right side of the dresser cabinet H and drawers D1-D4. In one embodiment, the cable guides 10, cable engagement devices 75, and the cable tensioning device 85 are located on the right-slide of panel P of dresser cabinet H about 3-5 inches from the front of dresser cabinet H (such that a user can outwardly slide a drawer D1-D4 from its nested position and reach his/her fingers into the dresser cabinet H to unhook the cable 87 from the cable engagement device 75, as described above).
Furthermore, although a “right side” view of the dresser cabinet H and drawers D1-D4 is seen at FIG. 20 showing one cable 87 being interfaced with a cable guide 10 and cable engagement device 75 corresponding to each drawer D1-D4, a second cable 87 may be provided on the “left side” of the dresser cabinet H that will correspondingly interfaced with “left side” cable guides 10 and cable engagement device 75 corresponding to each drawer D1-D4.
