Definitions
- the present invention relates to sliding door assemblies comprising roller assemblies for sliding doors of the type that slide along tracks, and, more particularly, to an anti-jump member engageable with the track to prevent the roller from derailing.
- Roller assemblies for sliding doors that move along a track are known in the art.
- a roller assembly may comprise a bracket for attached to the door, a roller mounting member slidably seated in the bracket and a roller mounted on the roller mounting member for travel along the track.
- An improved roller assembly of this type is disclosed in pending United States Patent Application Serial No. 08/583,281, assigned to our.
- a problem common to all such roller assemblies is derailing, which may occur if the door is struck or bumped, or if it encounters an obstruction on the track, or if force is not applied parallel to the track when the door is being opened or closed.
- the problem is exacerbated if the door is installed in a doorway which varies in height from one end to end or is not plumb.
- roller assembly which is specifically adapted for user installation.
- Another object is to provide such an assembly which is quiet in operation and inexpensive to produce.
- the present invention provides a sliding door assembly as claimed in claim 1, to which reference is directed.
- roller assembly 1 comprises a bracket 3, a roller mounting member 5 slideably seated in the bracket 3, a roller 7 rotatably mounted on the roller mounting member 5, and an anti-jump member 9 carried by the roller mounting member 5.
- the bracket 3 has a generally planar body portion 24 having an inner surface 17 upon which the roller mounting member 5 is slidable.
- side walls 26 each having outwardly extending flanges 38 and 40 at the ends thereof and an inwardly extending lip 28 centrally thereof.
- the side walls 26 and the body portion 24 define a channel in which roller mounting member 5 is seated, and the lip 28 retains the roller mounting member 5 therein.
- An end wall 30 extends perpendicularly to the upper end of the body portion 24 transversely across the width thereof between the side walls 26 to close the channel at its upper end.
- a flange 32 extends perpendicularly to the other or lower end of the bracket body 24 at its other end and in a direction opposite to the side walls 26 and end walls 30.
- a pair of holding tabs 34 which extend parallel to the plane of the body portion 24 and seat in the slots 12 in the bottom wall of the door rail 8.
- the holding tabs 34 on the flange 32 may be omitted, or removed or flattened, and the flange 32 may be connected to the rail 8 by screws passing through openings 31 in the flange 32 when the rail 8 is not adapted to receive the tabs 34, such as when the frame is formed from a hardwood greater than the thickness for which its channel was intended.
- the upper side flanges 38 on the bracket 3 and the lower side flanges 40 have generally planar body portions 42 and 44 extending generally parallel to the plane of the body portion 24.
- the planar body portion 42 of the flange 38 is formed with a generally G-shaped tab 50 which has a free end providing an inturned snap tip 51.
- the tabs 50 are generally coplanar with the planar portion 42 except for the snap tip 51 which is angled towards the plane of the body portion 24. This allows the tip 51 to pass into the slot 10 formed in the side of the door stile 6 and thereafter snap in place behind the interior surface of its side wall 13.
- An upwardly offset tab 52 on the flange 38 extends in a plane generally parallel to the plane of the bracket body portion 24 and is spaced above the plane of the planar portion 42. This co-operates with the G-shaped tab 50 and bears against the outer surface of the stile 6 to capture it therebetween.
- Each G-shaped tab 50 is provided with weakening section 56 which permits the tab 50 to be broken off in the event that the stile 6 is cut adjacent its end so that the slot 10 is no longer present or aligned therewith.
- the offset tab 52 is connected to the stile 6 by a screw (not shown) which extends through the aperture 54 in the tab 52.
- the weakening section 56 has an L-shaped slot 58 and a deformed region surrounding the slot 58 which allows the tab 50 to be broken off when a tool, such as a screwdriver tip, is inserted therein and moved back to flex the tab 50 until it breaks off.
- Each flange 42 also includes a notch 60 which receives the upper end wall 30 therewithin.
- the flange 42 has a portion 62 which extends behind the end wall 30 so as to abut the outer face of the end wall 30 and provide it with enhanced load bearing capacity. This is important because the weight of the door bears on the end wall 30 by forces imparted to it through the mounting member 86.
- the juncture of the body portion 24 and end wall 30 may be further stiffened by providing spot welds or staking gussets 64 therealong.
- the lower end flange 40 secures the lower end of the bracket 3 to the open end of the stile 6.
- the lower end flange 40 includes at its lower end an arm portion 65 which extends outwardly of and perpendicularly to the planar body portion 40 and provides a tab 66 which extends upwardly so as to engage the inner surface of the stile 6.
- the flange 40 has an upwardly offset, outwardly extending tab 53 which extends parallel to the body portion 24 along the outer surface of the stile 6.
- the tab 66 works in conjunction with the offset tab 53 to seat the wall of the stile 6 therebetween.
- the roller mounting member 5 is co-operatively dimensioned to slidingly seat in the channel of the bracket 3 and has a generally rectangular configuration with its upper end portion seated within the channel of the bracket 3 and its lower end portion extending below the bracket 3.
- the roller mounting member 5 has spaced side walls 76 and 78 which extend generally parallel to the plane of the body portion 24 of the bracket 3 and an end wall 82 at its upper end.
- the end wall 82 of the roller mounting member 5 is provided with an aperture 84 which threadably seats a machine screw 86 having a head 88 which abuts against the lower surface of the end wall 30 of the bracket 3 to transfer the door load to it.
- the end wall 82 is provided with reinforcements 29 adjacent the aperture 84.
- the screw 86 enables adjustment of the position of roller mounting member 5 and thereby the door height above the supporting surface and reduces play in the door by allowing the door to be moved upwardly snugly against the upper track (not shown).
- the end wall 30 has an access aperture 90 therein which permits a screwdriver blade to be inserted through the end wall 30 of the bracket 3 to engage the head 88 of the screw 86 in order to make such adjustments.
- the roller 7 is rotatably mounted adjacent the lower end of the mounting member 5 on an integral shaft or axle 92 which extends through aligned apertures in side walls 76 and 78.
- each of the apertures 72 includes an enlarged guide portion which allows the hub of the roller 7 to be snapped into place in the mounting member 5.
- a ball bearing 110 may be utilised between the roller hub 112 and the roller tire 114 as illustrated in Figure 14.
- the roller 7 comprises a wheel 7' integrally molded with the axle 92.
- the wheel 7' comprises a circular central portion 7a, forming a rim, flanked by two coaxial, circular, frusto-conical, side portions 7b, 7c.
- the side portions 7b, 7c are of smaller diameter than the central rim portion 7a and each side portion 7b, 7c tapers axially outwardly, that is, in a direction away from the central rim portion 7a.
- the track 100 resting on a base 202, is formed with two curved shoulders 204, 206 on either side of a curved central cavity 208.
- the two shoulders 204, 206 are situated at the top of the track 100, above the level of the base 202.
- the roller 7 runs on the track 100 by virtue of the side portions 7b, 7c of the roller 7 running on the shoulders 204, 206 respectively.
- the open top of the central cavity 208 of the track 100 forms a slot 210, level with the two shoulders 204, 206 and the cavity 208 widens out below the two, overhanging, shoulders 204, 206.
- the central portion 7a of the roller 7 extends through the slot 210 and below the level of the two shoulders 204, 206 into the cavity 208.
- the roller mounting member 5 is limited in its movement outwardly of the bracket 3 by a detent or tab 98 which extends inwardly from the body portion 24 and seats in an elongated slot 96 in the sidewall 78 of the roller mounting member 5.
- the detent 98 is resiliently deflectable to be deflected into the plane of the bracket body portion 24 when the upper end of the roller mounting member 5 is inserted into the bracket 3 until it springs into the slot 96 upon continued movement of the mounting member 5 toward the upper end flange 30 of the bracket 3.
- the anti-jump member 9 comprises a handle 91, an elongated shaft 93 extending downwardly therefrom and terminating at its bottom end in an enlarged track engagement portion 95.
- the anti-jump member 9 is rotatably and translatably carried by clips 87 on the side of the roller mounting member 5, adjacent the rim of the roller 7, with the shaft 93 lying in the roller median plane.
- the anti-jump member 9 is first rotated from the raised position shown in Figure 9 to the still raised position of Figure 10, then displaced longitudinally downwards to the lowered but inoperative position of Figure 11, and then rotated again to the operative position of Figure 12, wherein the track engagement portion 95 can engage the track 100, as best seen in Figure 7.
- a pair of recessed, flattened portions 94 formed in the shaft 93 of the anti-jump member 9 are selectively engageable with a locking member 89 disposed between the clips 87 to releaseably retain the anti-jump member 9 in the retracted position or the operative position as desired. It will be appreciated that the roller assembly 1 can move freely along the tracks with the anti-jump member 9 in either the lowered position or the raised position.
- the roller mounting member 5, with the roller 7 mounted therein may be initially inserted into the channel of the bracket 3 until the detent 98 snaps into the slot 96 of the mounting member 5. Thereafter, depending on whether the connector is to be used in a right or left corner of the panel, the side flanges 38 and 40 disposed along the corresponding right or left lateral side of the bracket 3 are used in the connection. In the illustrated example of Figure 5, the right corner of the door is being connected and those along the right side of the bracket 3 are used.
- the tab 66 is first engaged in the open end of the stile 6 and the tabs 34 of the lower end flange 32 are inserted into the slots 12.
- the bracket 3 is pivoted toward the slot 10 in the tile 6 until the G-shaped tab 50 is inserted through the slot 10 and the tip 51 snaps against the inner surface of the stile 6.
- the tabs 52, 53 seat against the outer surface of the stile 6 and the body portion 24 seats against the outer surface of the rail 8 to engage the stile 6 and rail 8 firmly with the bracket 3.
- the stiles and rails are conventionally fabricated from steel or aluminium to provide a rigid frame while providing some degree of flexure to grip the panel securely.
- the bracket is conveniently stamped from sheet metal of about 0.030-0.050 inch thickness.
- the roller mounting member, roller and anti-jump member are conveniently molded from synthetic resin such as nylon, polypropylene and acetal.

Description
- The present invention relates to sliding door assemblies comprising roller assemblies for sliding doors of the type that slide along tracks, and, more particularly, to an anti-jump member engageable with the track to prevent the roller from derailing.
- Roller assemblies for sliding doors that move along a track are known in the art. Advantageously, such a roller assembly may comprise a bracket for attached to the door, a roller mounting member slidably seated in the bracket and a roller mounted on the roller mounting member for travel along the track. An improved roller assembly of this type is disclosed in pending United States Patent Application Serial No. 08/583,281, assigned to ourselves.
- A problem common to all such roller assemblies is derailing, which may occur if the door is struck or bumped, or if it encounters an obstruction on the track, or if force is not applied parallel to the track when the door is being opened or closed. The problem is exacerbated if the door is installed in a doorway which varies in height from one end to end or is not plumb.
- Many sliding doors are intended for installation by the user, the so called "do-it-yourself" market. Products in this market must be simple to install, using only commonly available tools.
- Accordingly, it is an object of the present invention to provide a novel roller assembly for a tracked sliding door which resists derailing.
- It is also an object to provide such a roller assembly which is specifically adapted for user installation.
- Another object is to provide such an assembly which is quiet in operation and inexpensive to produce.
- The present invention provides a sliding door assembly as claimed in claim 1, to which reference is directed.
- The invention will be described by way of example with reference to the drawings.

-
- Referring to the drawings, therein illustrated is a roller assembly of a sliding door assembly embodying the present invention. The roller assembly is generally designated by the numeral 1. Roller assembly 1 comprises a
bracket 3, aroller mounting member 5 slideably seated in thebracket 3, aroller 7 rotatably mounted on theroller mounting member 5, and ananti-jump member 9 carried by theroller mounting member 5. - The
bracket 3 has a generallyplanar body portion 24 having aninner surface 17 upon which theroller mounting member 5 is slidable. Along the sides thereof areside walls 26 each having outwardly extendingflanges side walls 26 and thebody portion 24 define a channel in whichroller mounting member 5 is seated, and the lip 28 retains theroller mounting member 5 therein. - An
end wall 30 extends perpendicularly to the upper end of thebody portion 24 transversely across the width thereof between theside walls 26 to close the channel at its upper end. Aflange 32 extends perpendicularly to the other or lower end of thebracket body 24 at its other end and in a direction opposite to theside walls 26 andend walls 30. Along the free end of theflange 32 is a pair ofholding tabs 34 which extend parallel to the plane of thebody portion 24 and seat in theslots 12 in the bottom wall of the door rail 8. While illustrated as part of thebracket 3, it should be understood that theholding tabs 34 on theflange 32 may be omitted, or removed or flattened, and theflange 32 may be connected to the rail 8 by screws passing throughopenings 31 in theflange 32 when the rail 8 is not adapted to receive thetabs 34, such as when the frame is formed from a hardwood greater than the thickness for which its channel was intended. - The upper side flanges 38 on the
bracket 3 and thelower side flanges 40 have generallyplanar body portions 42 and 44 extending generally parallel to the plane of thebody portion 24. Theplanar body portion 42 of theflange 38 is formed with a generally G-shaped tab 50 which has a free end providing an inturnedsnap tip 51. The tabs 50 are generally coplanar with theplanar portion 42 except for thesnap tip 51 which is angled towards the plane of thebody portion 24. This allows thetip 51 to pass into theslot 10 formed in the side of thedoor stile 6 and thereafter snap in place behind the interior surface of itsside wall 13. Anupwardly offset tab 52 on theflange 38 extends in a plane generally parallel to the plane of thebracket body portion 24 and is spaced above the plane of theplanar portion 42. This co-operates with the G-shaped tab 50 and bears against the outer surface of thestile 6 to capture it therebetween. - Each G-shaped tab 50 is provided with weakening
section 56 which permits the tab 50 to be broken off in the event that thestile 6 is cut adjacent its end so that theslot 10 is no longer present or aligned therewith. In this circumstance, theoffset tab 52 is connected to thestile 6 by a screw (not shown) which extends through theaperture 54 in thetab 52. The weakeningsection 56 has an L-shaped slot 58 and a deformed region surrounding theslot 58 which allows the tab 50 to be broken off when a tool, such as a screwdriver tip, is inserted therein and moved back to flex the tab 50 until it breaks off. - Each
flange 42 also includes anotch 60 which receives theupper end wall 30 therewithin. Thus, theflange 42 has aportion 62 which extends behind theend wall 30 so as to abut the outer face of theend wall 30 and provide it with enhanced load bearing capacity. This is important because the weight of the door bears on theend wall 30 by forces imparted to it through themounting member 86. The juncture of thebody portion 24 andend wall 30 may be further stiffened by providing spot welds or stakinggussets 64 therealong. - The
lower end flange 40 secures the lower end of thebracket 3 to the open end of thestile 6. Thelower end flange 40 includes at its lower end anarm portion 65 which extends outwardly of and perpendicularly to theplanar body portion 40 and provides atab 66 which extends upwardly so as to engage the inner surface of thestile 6. At its upper end, theflange 40 has an upwardly offset, outwardly extendingtab 53 which extends parallel to thebody portion 24 along the outer surface of thestile 6. Thetab 66 works in conjunction with theoffset tab 53 to seat the wall of thestile 6 therebetween. - The
roller mounting member 5 is co-operatively dimensioned to slidingly seat in the channel of thebracket 3 and has a generally rectangular configuration with its upper end portion seated within the channel of thebracket 3 and its lower end portion extending below thebracket 3. Theroller mounting member 5 has spacedside walls body portion 24 of thebracket 3 and anend wall 82 at its upper end. - The
end wall 82 of theroller mounting member 5 is provided with anaperture 84 which threadably seats amachine screw 86 having a head 88 which abuts against the lower surface of theend wall 30 of thebracket 3 to transfer the door load to it. Theend wall 82 is provided withreinforcements 29 adjacent theaperture 84. Thescrew 86 enables adjustment of the position ofroller mounting member 5 and thereby the door height above the supporting surface and reduces play in the door by allowing the door to be moved upwardly snugly against the upper track (not shown). Theend wall 30 has an access aperture 90 therein which permits a screwdriver blade to be inserted through theend wall 30 of thebracket 3 to engage the head 88 of thescrew 86 in order to make such adjustments. - As best seen in Figures 1 and 2, the
roller 7 is rotatably mounted adjacent the lower end of themounting member 5 on an integral shaft oraxle 92 which extends through aligned apertures inside walls roller 7 to be snapped into place in themounting member 5. Alternatively, a ball bearing 110 may be utilised between theroller hub 112 and theroller tire 114 as illustrated in Figure 14. - As clearly shown in the drawings, and particularly figure 6, the
roller 7 comprises a wheel 7' integrally molded with theaxle 92. The wheel 7' comprises a circularcentral portion 7a, forming a rim, flanked by two coaxial, circular, frusto-conical,side portions 7b, 7c. Theside portions 7b, 7c are of smaller diameter than thecentral rim portion 7a and eachside portion 7b, 7c tapers axially outwardly, that is, in a direction away from thecentral rim portion 7a. As shown best in Figures 6 and 7, thetrack 100, resting on a base 202, is formed with twocurved shoulders shoulders track 100, above the level of the base 202. Theroller 7 runs on thetrack 100 by virtue of theside portions 7b, 7c of theroller 7 running on theshoulders track 100 forms aslot 210, level with the twoshoulders central portion 7a of theroller 7 extends through theslot 210 and below the level of the twoshoulders - The
roller mounting member 5 is limited in its movement outwardly of thebracket 3 by a detent ortab 98 which extends inwardly from thebody portion 24 and seats in anelongated slot 96 in thesidewall 78 of theroller mounting member 5. Thedetent 98 is resiliently deflectable to be deflected into the plane of thebracket body portion 24 when the upper end of theroller mounting member 5 is inserted into thebracket 3 until it springs into theslot 96 upon continued movement of the mountingmember 5 toward theupper end flange 30 of thebracket 3. - As best seen in Figures 3 and 4, the
anti-jump member 9 comprises ahandle 91, anelongated shaft 93 extending downwardly therefrom and terminating at its bottom end in an enlargedtrack engagement portion 95. Theanti-jump member 9 is rotatably and translatably carried byclips 87 on the side of theroller mounting member 5, adjacent the rim of theroller 7, with theshaft 93 lying in the roller median plane. As illustrated in Figures 9-12, theanti-jump member 9 is first rotated from the raised position shown in Figure 9 to the still raised position of Figure 10, then displaced longitudinally downwards to the lowered but inoperative position of Figure 11, and then rotated again to the operative position of Figure 12, wherein thetrack engagement portion 95 can engage thetrack 100, as best seen in Figure 7. - In the lowered, operative, position of the
anti-jump member 9, shown in Figures 7 and 12, theshoulders track 100 overhang parts of thetrack engagement portion 95 as shown, so that thetrack engagement portion 95 cannot be withdrawn from thetrack 100. When the, still lowered, anti-jump member is rotated to the inoperative position shown in Figures 10 and 11, theshoulders track 100 no longer overhang any part of thetrack engagement portion 95, so that thetrack engagement portion 95 can be displaced longitudinally, that is, vertically, to be inserted into or withdraw from the cavity 208, through theslot 210, as desired. - A pair of recessed, flattened
portions 94 formed in theshaft 93 of theanti-jump member 9 are selectively engageable with a lockingmember 89 disposed between theclips 87 to releaseably retain theanti-jump member 9 in the retracted position or the operative position as desired. It will be appreciated that the roller assembly 1 can move freely along the tracks with theanti-jump member 9 in either the lowered position or the raised position. - In assembling the connector to the panel 2 and
frame elements 6, 8, theroller mounting member 5, with theroller 7 mounted therein, may be initially inserted into the channel of thebracket 3 until thedetent 98 snaps into theslot 96 of the mountingmember 5. Thereafter, depending on whether the connector is to be used in a right or left corner of the panel, theside flanges bracket 3 are used in the connection. In the illustrated example of Figure 5, the right corner of the door is being connected and those along the right side of thebracket 3 are used. Thetab 66 is first engaged in the open end of thestile 6 and thetabs 34 of thelower end flange 32 are inserted into theslots 12. Thereafter, thebracket 3 is pivoted toward theslot 10 in thetile 6 until the G-shaped tab 50 is inserted through theslot 10 and thetip 51 snaps against the inner surface of thestile 6.
