Description

BACKGROUND AND SUMMARY

This invention relates generally to drawer slides. More particularly, this invention relates to drawer slides having a component for attachment to a drawer and a component for attachment to a frame whereby when the drawer is received in the frame a stop is actuated to permit removal of the drawer from the frame.

Drawer slides are known having components for attachment to a drawer and components for attachment to a frame within which the drawer is to be received. Often such drawer slides include retention and release mechanisms that retain the drawer component within the frame component or vice versa until the release mechanism is actuated. Often the retention and release means are difficult to operate or of complicated manufacture.

The drawer slide assembly disclosed herein is easily operable and of simple manufacture.

A drawer slide assembly in accordance with the present invention includes a channel, a slide member or rail, and a carriage. The channel has an outward first end and an inward second end and is formed to include a detent. The slide member has an outward first end, an inward second end, and a tab. The carriage is disposed within the first channel for longitudinal movement therein. The carriage includes a flexible finger and a stop. The stop is configured to contact the detent whereby the travel of the carriage is limited relative to the channel. The slide member is configured to be longitudinally moveably received within the carriage. When the slide member is received within the carriage, the flexible finger limits the outward travel of the slide member by contacting the tab.

Additional features and advantages of the invention will become apparent to those skilled in the art upon consideration of the following detailed description of illustrated embodiments exemplifying the best mode of carrying out the invention as presently perceived.

DETAILED DESCRIPTION OF THE DRAWINGS

An illustrative embodiment of a drawer slide assembly 10 in accordance with the present invention is shown in FIG. 1 . Drawer slide assembly 10 includes a channel 20 , a carriage 60 , and a rail 40 , which cooperate to form assembly 10 . Further reference is made to FIG. 12 which shows assembly 10 in cooperation with a drawer 80 and a frame 90 .

Referring to FIG. 12 , drawer slide assembly 10 , drawer 80 , and frame 90 are illustrated in an exploded view. Rail 40 of drawer slide assembly 10 slides within carriage 60 . Drawer 80 includes a bottom panel 81 , first and second side panels 86 , 88 , respectively, face panel 83 , and rear panel 85 cooperating to form an upwardly opening cavity. Frame 90 includes a drawer opening defined by upwardly facing surfaces 91 , opposed inwardly facing side surfaces 96 , 98 , and a downwardly facing surface 97 . Drawer opening is sized to receive bottom panel 81 , first side panel 86 , second side panel 88 , and rear panel 85 of drawer 80 therein. As shown, in FIG. 12 , channel 20 is configured for attachment to frame 90 and rail 40 is configured for attachment to drawer 80 . Carriage 60 rides within channel 20 and rail 40 rides in carriage 60 to facilitate movement of drawer 80 relative to frame 90 .

Carriage 60 includes flexible finger 62 , a stop 64 to contact at least one of the detents 26 , 28 , 30 whereby the travel of carriage 60 is limited relatively to channel 20 . Rail 40 is disposed within carriage 60 and is longitudinally moveable therein. Flexible finger 62 limits the outward travel of rail 40 by contacting tab 46 . Thus, when used in cooperation with drawer 80 and frame 90 as shown in FIGS. 1 and 12 , drawer 80 may slide freely within frame 90 but flexible finger 62 in cooperation with tab 46 stops drawer 80 from inadvertently traveling beyond the confines of frame 90 . Although the illustrated embodiment shows assembly 10 in an undermount position relative to drawer 80 , it is to be understood by those skilled in the art that the present invention is envisioned to be equally applicable to mounting on sides 86 , 88 of drawer 80 and sides 96 and 98 of frame.

Those skilled in the art will recognize that drawer slide assembly 10 is depicted having channel or first track 20 attached to upwardly facing surface 91 of frame 90 and rail or second channel 40 attached to underside of bottom panel 81 of drawer 80 . By such arrangement, drawer slide assembly 10 is illustrated as being mounted as an under drawer slide. The terms upwardly, downwardly, inwardly and outwardly, and similar adverbial or adjectival terms will be used herein in describing drawer slide assembly 10 with the understanding that those terms accurately reflect the orientation of components of drawer slide assemblies mounted as under drawer slides. However, the usage of such directional terms is not intended to limit the scope of the invention to under drawer slides, since it is within the scope of the disclosure as presently perceived to mount drawer slide assembly 10 to drawer 80 and frame 90 in different fashions, eg mounting a single drawer slide assembly to a side panel 86 or 88 of drawer 80 , mounting a drawer slide assembly to each side panel 86 and 88 of drawer 80 , etc.

Channel or outer track 20 has a first end 22 , a second end 24 , a bottom portion 36 , a first side flange 32 , and a second side flange 34 . Bottom portion 36 is formed to include at least one detent 30 . In the illustrated embodiment, two additional detents 26 and 28 are shown but it is to be understood that multiple detents are not necessary. Referring to FIG. 12 , the exploded view indicates that in use, first end 22 of channel 20 is attached to an outward, proximal portion 92 of frame 90 and second end 24 of channel 20 is attached to an inward, distal portion 94 of frame 90 .

Referring to FIGS. 1 and 11 , channel or outer track 20 is illustrated. Illustratively, channel 20 is formed from a metallic material which is formed and stamped to create the features of channel 20 . First side flange 32 and second side flange 34 are spaced-apart with bottom portion 36 extending therebetween. Bottom portion 36 is substantially planar along the length and width of channel 20 to facilitate secure fastening of channel 20 to frame 90 . Bottom portion 36 is formed to include attachment holes 37 extending therethrough within which fasteners (not shown) are received for fastening channel 20 to frame 90 .

Illustratively, bottom portion 36 of channel 20 is formed to include two upwardly extending outward detents 28 and 30 adjacent first end 22 of channel 20 and an upwardly extending medial detent 26 disposed between outward detents 28 and 30 and second end 24 . Illustratively, detents 26 , 28 , 30 are stamped in bottom portion 20 . Outward detents 28 , 30 incline rearwardly while medial detent 26 inclines forwardly.

In the illustrated embodiment, the metallic material of channel 20 is bent to form first side flange 32 and second side flange 34 . As shown in FIG. 11 , first and second side flanges 32 and 34 , respectively, include a first portion 29 extending laterally outwardly and upwardly (assuming channel 20 is mounted to an upwardly facing surface of frame 90 ) from side edges of bottom portion 20 and a second portion 31 extending inwardly and upwardly from first portion 29 . As shown for example in FIG. 11 , channel has a substantially diamond C-shaped cross-section.

Slide member, inner track, or rail 40 has a first end 42 , a second end 44 , a top portion 52 , a first side wall 48 , a second side wall 50 , and outwardly extending lips 49 and 51 . First side wall 48 and second side wall 50 are spaced-apart with top portion 52 extending therebetween. Illustratively, top portion 52 is substantially planar to facilitate attachment of rail 40 to the underside of bottom panel 81 of drawer 80 . First end 42 of rail 40 is attached to an outward, proximal portion 82 of drawer 80 and second end 44 of rail 40 is attached to an inward, distal portion 84 of drawer 80 . Carriage 60 , also shown in FIGS. 2 and 3 , is disposed within the channel 20 and is longitudinally moveable therein.

A lip 49 , 51 extends outwardly from the bottom end of each of first and second walls 48 and 50 , respectively. Rail 40 is substantially symmetrical about its longitudinal axis 41 . Top portion 52 is formed to include attachment holes 58 through which fasteners (not shown) extend to attach rail 40 to drawer 80 . As shown in FIG. 11 , rail 40 has a substantially box U-shaped or box Q-shaped cross section. Like channel 20 , rail 40 is illustratively formed of a metallic material to facilitate forming of part through standard stamping, cutting and bending operations. Those skilled in the art will recognize that rail 40 and channel 20 can be made from non-metallic materials within the scope of the invention.

Top portion 52 is formed to include a downwardly projecting tab 46 . Illustratively, tab 46 is formed by cutting or stamping a laterally extending strip in top portion 52 , cutting strip near second side wall 50 and bending strip near longitudinal axis 41 so that tab 46 extends downwardly adjacent longitudinal axis 41 .

Referring now to FIGS. 2 , 3 , and 11 in one embodiment carriage 60 is formed to include a base 72 , pairs of guide tabs 74 , and a flexible finger 62 . Base 72 includes a bottom portion 76 , a top portion 78 , and a stop 74 projecting from bottom portion 76 . Illustratively, bottom portion 76 of base 72 has atop surface 75 and a bottom surface 77 and is formed from longitudinally extending first and second sides 63 and 65 , respectively, and crossmembers 67 , 69 , 71 , 73 . Front crossmember 67 , forward middle cross member 69 , first side 63 , and second side 65 define a front rectangular opening 110 . Forward middle cross member 69 , rearward middle cross member 71 , first side 63 , and second side 65 define a middle rectangular opening 112 . Rearward middle cross member 71 , rear cross member 73 , first side 63 , and second side 65 define a rear rectangular opening 114 . Those skilled in the art will recognize that front rectangular opening 110 provides free space within which finger 62 may be flexed and thus the rectangular shape of the opening should not act as a limitation on the scope of the disclosure. Middle and rear rectangular openings 112 and 114 , respectively and areas of front rectangular opening 110 , serve merely to reduce the material requirements of carriage 60 .

Base 72 is formed to include a stop 64 projecting downwardly from bottom surface 77 of bottom portion 76 . As shown in FIG. 5 , Stop 74 is preferably formed to have sharp edges to engage detent 30 to limit the travel of carriage 60 within channel 20 . In the illustrated embodiment, stop 64 is a transverse ridge extending downwardly from forward middle cross member 69 .

Top portion 78 extends upwardly from top surface 75 of first and second sides 63 and 65 , respectively. Top portion 78 includes a plurality of pairs of guide tabs 74 extending laterally inwardly toward longitudinal axis 61 . Each pair of guide tabs 74 are positioned to be in spaced-apart and confronting relationship to one another on opposite sides of the carriage 60 to define a track 75 therebetween within which side walls 48 and 50 and top portion 52 of rail 40 are slidably received for longitudinal movement relative to carriage 60 . Outwardly extending lips 49 , 51 of rail 40 are slidably disposed within carriage 60 between the bottom surface of associated guide tabs 74 and top surface 77 of sides 63 and 65 of bottom portion 76 . The pairs of guide tabs 74 are positioned to define a track 75 for receipt of rail 40 .

Carriage 60 is configured to be disposed within channel 20 for longitudinal movement therein. Illustratively, carriage 60 is slidably embraced by angled blades 33 and 35 of side flanges 32 and 34 . As shown, for example, in FIG. 11 carriage 60 has a diamond C-shaped cross section facilitating receipt of carriage 60 within channel 20 .

In the illustrated embodiment, when carriage 60 is disposed within channel 20 , carriage 60 is free to move longitudinally within channel 20 between limits. Stop 64 of carriage 60 and both front detents 30 and 28 of channel 20 , upon contact, cooperate to limit the outward movement of carriage 60 relative to channel 20 . Those skilled in the art will recognize that outward movement of carriage 60 within channel 20 may be limited by transverse ridge contacting a single front detent or by other properly configured structural elements of carriage 60 and channel 20 . Stop 64 of carriage 60 and medial detent 26 of channel 20 , upon contact, cooperate to limit inward movement of carriage 60 with respect to channel 20 .

As previously stated, carriage 60 is further formed to include flexible finger 62 which cooperates with tab 46 of rail 40 to selectively limit outward movement of rail 40 with respect to carriage 60 . Illustratively, flexible finger 62 includes a fixed end 120 and a free end 122 . Fixed end 120 is attached to front cross member 67 so as to be offset from longitudinal axis 61 toward first side 63 by a distance 126 sufficient to allow tab 46 of rail 40 to slide past fixed end 120 without interference from fixed end 120 when rail 40 is inserted into track 75 of carriage 60 . Finger 62 extends upwardly from bottom portion 76 a distance 128 sufficient to allow a portion of free end 122 to engage a portion of tab 46 . Finger 62 extends longitudinally from fixed end 120 to free end 122 which is displaced toward second end 24 of channel 20 when the carriage 60 is disposed within channel 20 . Finger 62 extends laterally inward toward longitudinal axis 61 from fixed end 120 toward free end 122 so that free end 122 is disposed adjacent longitudinal axis 61 when finger 62 is in its natural, first position 66 .

Finger 62 is disposed within front rectangular opening 110 to permit finger 62 to be flexed laterally. Illustratively, a stop 130 extends from second side 65 of bottom portion 76 inwardly into front rectangular opening 110 to restrict flexation of finger 62 so that finger 62 can only be flexed toward first side 63 . Raised tactile indicators 132 are formed on the bottom 135 and second side 136 of finger 62 to provide a user with a tactile indicator of the side of finger 62 which should be pushed to flex finger 62 toward first side 63 of bottom portion 76 .

In the illustrated embodiment, when finger 62 is in the first natural position 66 , and rail 40 is slidably received in carriage 60 , free end 122 of the finger 62 lies along a common longitudinal axis 41 , 61 with tab 46 . As rail 40 is moved outwardly with respect to carriage 60 , tab 46 engages free end 122 of flexible finger 62 when finger 62 is in the first natural position 66 to limit outward motion of rail 40 with respect to carriage 60 . When finger 62 is in flexed position 68 , tab 46 moves freely beyond the finger 62 to allow rail 40 to be removed from carriage 60 and thus allow drawer 80 to be removed from frame 90 .

In a preferred embodiment, guide tabs 74 include chamfered edges 77 . (Best seen in FIG. 2. ) Also in a preferred embodiment, carriage 60 is formed from high density polyethylene (HDPE). HDPE is especially suited to this application since it is a relatively inexpensive material, easily formed, durable and self-lubricating in the instant application. However, those skilled in the art will recognize that carriage may be manufactured from other materials within the scope of the invention.

In use, channel 20 is attached to frame 90 by nails, screws, staples, or other suitable fasteners (not shown). Channel 20 is positioned on frame 90 such that detents 26 , 28 , 30 face upward. Detents 28 , and 30 which are formed at the first end 22 of the channel 20 , are at the outward, proximal position 92 of the frame 90 . In a preferred embodiment, a third detent 26 is formed between first end 22 and second end 24 of channel 20 .

In use, rail 40 is attached to drawer 80 by nails, screws, staples, or other suitable means (not shown). Rail 40 is positioned on drawer 80 such that tab 46 faces downward when drawer 80 is in its normal position.

Referring to FIGS. 6-10 , carriage 60 is slidably received in channel 20 and rail 40 is slidably received within guide tabs 74 . In the preferred embodiment, stop 64 rides up over the inclined portion of detents 28 , 30 formed at first end 22 of channel 20 . Carriage 60 is slidably and limitedly disposed within the channel 20 to move between an outer limit and an inner limit. When the carriage 60 slides outwardly, stop 64 strikes detents 28 , 30 and outward travel of carriage 60 is limited. When carriage 60 slides inwardly, stop 64 strikes detent 26 and the inward travel of the carriage 60 is limited.

To mount the drawer 80 within the frame 90 , rail 40 is slidably disposed within track 75 defined by guide tab pairs 74 of carriage 60 . As drawer 80 with attached rail 40 is slid into track 75 , tab 46 urges flexible finger 62 from its first, natural position 66 to its second, flexed position 68 . When finger 62 is in its flexed position 68 , finger 62 passes beyond tab 46 . After tab 46 passes beyond flexible finger 62 , flexible finger 62 returns to its first, natural position 66 . It will be appreciated by those skilled in the art, that the placement of detents 26 , 28 , 30 in combination with the dimensions of carriage 60 and the placement of stop 64 and flexible finger 62 may be designed to control the degree of travel of drawer 80 relative to frame 90 .

In operation, assembly 10 provides a smooth mechanism for aligning drawer 80 in frame 90 and maintaining the position of drawer 80 within frame 90 . When installed, drawer 80 is constrained from traveling outwardly by contact between flexible finger 62 and tab 46 . Conveniently, when it is desirous to remove the drawer 80 from frame 90 , manual movement of flexible finger 62 from first, natural position 66 where it is in longitudinal alignment with tab 46 to the second, flexed position 68 where it is not in longitudinal alignment with tab 46 enables drawer 80 to be removed from frame 90 .

Those skilled in the art will recognize that during insertion of drawer 80 into frame 90 , lips 49 , 51 of rail 40 are inserted into a gap 134 between bottom surface of guides 74 and top surface 63 of bottom portion of carriage 60 , and rail 40 is slid rearwardly within carriage 60 . Initially carriage 60 slides rearwardly within channel until stop 64 engages medial detent 26 while lips 49 , 51 of rail 40 slide within guide gaps 134 . During insertion of rail 40 into track 75 of carriage 60 , tab 46 eventually engages second side 136 of finger between fixed end 120 and free end 122 . Upon further insertion, tab 46 urges finger 62 to flex toward first side 63 of carriage 60 until tab 46 passes inwardly beyond free end 122 of flexible finger 62 . Upon tab 46 passing inwardly beyond free end 122 of flexible finger 62 , flexible finger 62 returns to its natural first position 66 .

Although the invention has been described in detail with reference to a certain preferred embodiment, variations and modifications exist within the scope and spirit of the present invention as described and defined in the following claims.
