United States Patent Filed Aug. 7, 1959, Ser, No. 832,307 6 Claims. (Cl. 16"-105) This invention relates in general to hardware, and more particularly to improvements in sliding door hanger assemblies utilized for mounting a door or panel on a supporting track.

Hanger assemblies to support sliding doors or panels for movement along a track are generally known in the art; such normally including some type of mounting bracket means ordinarily attachable adjacent one end of a door to be supported and having one or more rollers for engaging a normally horizontal overhead track. Usually, two such hanger assemblies are used for each door, one near each upper corner. If the alignment of the hanger assemblies and the door jamb is closely supervised,the door ideally will lie in a generally vertical plane with its lateral edges plumb with the vertical or 'side jamb members. Such ideal installations are seldom if ever achieved or maintained, however, without adjusting the door alignment, particularly in new buildings which are prone to settling. It is especially desirable, therefore, to provide means for adjusting the door relative to the door jamb and track. AThis may be accomplished conveniently by embodying adjustment means in the hanger assembly for repositioning the door, as is intended by the present invention.

Previous inventors havepresented hanger assemblie embodying a wide variety of means for accomplishing the aforementioned objective, but it has been our experience that such prior devices generally have been ineffective for one reason or another. One familiar type, for example, requires repositioning movement of the entire hanger assembly, particularly the mounting bracket, relative to the door. This manner of accomplishing the needed adjustments is lunduly cumbersome and produces excessive wear of the fastener means and its connection vwith the door, eventually resulting in an insecure mounting for the assembly, which is incapable of maintaining a desired position of door adjustment. As a result the problem of maintaining a sliding door in proper alignment and position for accurate and smooth operation has remained as a serious one to the user.

The present invention meets this problem by providing an improved hanger assembly including an improved means for adjustably positioning the track-engaging rollers thereof relative to a related door. In brief, this invention comprises a mounting bracket adapted to receive screw attachment means for fixing the same stationarily to one face of a door or panel member to be supported for sliding movement along an overhead track. A hanger bracket, carrying roller means at its upper end for engaging the track, is juxtaposed between the `mounting bracket and door, and adapted for sliding movement relative to the latter between predetermined Adjustment means, carried on the mounting bracket, comprises a rotatable eccentric pin means which engages an opening in the hanger bracket for rectilinearly reciprocating the latter relative to the mounting bracket and door, thereby achieving an infinite number of adjusted positions for the roller means relative to For maximum convenience, the eccentric means is accessible for operational engagement at one face of the mounting bracket and may be rotated by using a screwdriver or like tool. A locking means is also provided for holding the mounting and hanger 2,999,267 vPatented Sept. 12, 1961 brackets together and for locking the same at selected positions of-relative adjustment, determined by the operation of the adjustment means. I The main object of this invention is to provide anew and improved hanger assembly for use in mounting doors or like panel members for movement along a track. Another object of this invention is to provide a hanger assembly as aforesaid which embodies improved means for its adjustment. f f

An additional object of this invention is to provide a new and improved hanger assembly which embodies'improved means for adjustably positioning, plumbing, and aligning a sliding door in a door opening; the door normally being suspended from an overhead track by a paix' of such assemblies.

Another important object of this invention is to provide a hanger assembly which is adjustable to align'a related door as aforesaid, without requiring vadditional means for holding or supporting the door in the desired position while such adjustment is carried out.

A further object of this invention is to provide a new and improved hanger assembly for suspending sliding doors from an overhead track which employs a rotatable eccentric means for adjustably positioning the rollers of the hanger assembly relative to the upper end of an associated door for the purpose of adjusting the position and alignment of the door in a related opening. y Still another object of this invention is to providea new and improved `hanger assembly as aforesaid which in addition to the said adjustment means also includes means for locking the assembly in selected positions of adjustment.

A still further object of this invention is to provide a new and improved hanger assembly embodying improved features -of adjustability, convenience, and simplicity of manufacture and operation.

The above and further objects, features, and advantages of this invention will appear to those familiar with the art from the vfollowing detailed description of preferred and modified forms of the invention, illustrated in the accompanying drawings.

Atypical sliding door v.installation is villustrated .in FIGURE 1, showing the general operational features and modebf employing hangerassemblies according to thxsrnventlon. In bypassing doorl installations .as Vshown therein, -two doors -10 andfll are-normally `guided at their bottom endsto move in parallel ver-ticalplanes alongthe parallel paths defined by overhead track mee-ns 14 from which they are suspended by hanger assemblies 12.and 12'. YBrielyfeach of two sliding doors 10 `and 11, aligned in parallel vertical `planes yastherein shown, is equipped with a pair of hanger assemblies 12,12' accord* ing to this invention; one `such assembly being located adjacent each upper cornerand topfedge 13 of the door or panel 10, tor instance. The two hangerassemblies 12, 12' on door 10, therefore, constitute the only means connecting and supporting the door from overhead track 14, the latter of which is mounted substantially horizontallyacross the upper end of thedoor-` opening as deined by Sl'llOfllral frame and iamb members.indcatedgenerally by numeral 15 in FIGURE 1,

-With'refcrence to-FIGS. 2f-5 ofthe-drawing.- it will be recognized VVand understood that a flrst form ofi hanger essen-:bly i12. `is therein illustrated which includes va mounting bracket 20, a cooperatinghanger bracket indic-ated ygenerally by the numeral '21, adjustment-means 22 associated withvboth brackets `20. and 21, and locking means -23 for fixing brackets Ztl and ,-21 in desired positions of adjusted -movemenbas determinedby-operation of adjustment means 2 2. The details of the various elements and means m-2.3 will nowbefset out along withtheir related appurtenances.

Mounting bracket-20 is preferably stamped Afrom sheet metal or likematen'al to include apair of coplanar aligned `lateral .mounting-llange. portions 25,--25- flanking a central body portion 26 thereof; the latter comprising n generally rectangular plateA set out from theplane of flange portionsziy -25 and further distinguished by-a Central offset, or raised longitudinal-:platform portion 27. '4l-'he body portion alsoY has a pair of ears-28,2Sfextending vat right angles thereto, one at each-of its upper corners,

and comprising integral extensions of sidewall portions-29, 29 which dene the laterallimitsof Ithe .bodyportion 2.6. Walls 2.9, 29 are later-ally spaced --and perform as -guideways for locating and piloting the hanger bracket 2:1 for rectilinearl reciprocating movement behind the `main body portion 26, as will presently appear. The ears 2S arefparticularly `utilized to locate the mounting-bracket 20 at a desired upright position 'pat the-upperendof the door 10; such ears extending overand engagingthe upper end 13 od the door (seerFlGVZ).

The mounting flanges 25,. are'eachsuitably provided with a central opening receptive of fasteningmeans, such as a wood screw 30. Thus, with the location of the mounting bracket 2.0 over one face 31 of the door, land in an upright position set by the locating

ears

28, 28, fastening bracket 20 to the door 10 is easily accomplishedrby passing the wood screws 430, 30, or like fastening devices, through the openingsV inV the mounting brackety portions 25 for threading engagement with the door therebeneath. It is a feature of this invention thatA once'so Xedin position, mounting bracket 2b neednot thereatter be removed or therein to accomplish any-desired kadjustment;of the hanger bracket Z1, when plumbingand aligning the door in' the jamb 15.

'd wise of the mounting bracket =for cooperation with a locking means 23, such as a screw having a slotted head 34 adapted to receive the blade of a screwdriver or like instrument.

'Ilhe shank of the locking screw extends through the slotted openingf`33 Yofthe mounting kbracket andthreadingly Vengages `,the ywall .of an opening 35 inthe hanger bracket 21, as viewed best in FIG. 4. With this arrangement, the renlarged head 34 of the locking means 23 is adapted to engage the sloping'sidewalls of opening 33 to ifrictionally pull the hanger bracket to the mounting bracket at desired. adjusted positions of relative movement thereof as will =be described.

Platform portion 27 also includes an enlarged circular opening 38 below slot 33 through which a circular head portion y40 of the adjustment means 22 projects; said head end also having aslotted opening 41 receptiveof a screwdriver blade or the like, used to operate the adjustment means V22. It will be recognized additionally that the lower endof .the platforml portion 27V is formed with a semi-circular wall portion 43. This accommodates and provides a guideway for the circular-shaped lactjusti'nent means V22, especially as the latter is rotated.

As best-seen itl-FIGS. 3 and 4, thehanger bracketll is'stamped or otherwise .formed toV include a main body portiondt whichlbears a profile conguration conform, ing to the main' bodyportion 26 of the mounting bracket; Such body portion 45 is provided with-an elongated oval opening 46 symmetrically aligned on the longitudinal center lineof the body portion 4S and generally located yto one side of the .latters midpoint. Opening` 46 is further aligned with its longitudinal anis transverse to the length- `wiseeuiis of body portion .45 so that. it may cooperate with the adjustment .means 22, as will be described. Additionally, the upper end of Ythe body portion d5A is turnedinwardlyat an angle to `form an inclined arm portion@ which is adapted to overhang theupper end 11i-ofthe. door, all in the manner best seen inFlG. 4. v-Arrn portion 47 further informed integrally -with la substantially vertically extending upper linger portion .48 which approximatelyparallels the plane of the brackets body portion 45 and is provided .for the purpose of supporting connection with a single roller or a crossarm assembly 50 associated with multiple rollers. .It Will be seen that the` main body portion 45, the inclined arm, portion 47, and the linger portion 48 of the hanger bracket, are ribbed by parallel extending raised projections or

ribs

51, 51 integrally joined at their one end with a raised island section 52 formed near the upper end of the body portion 45 Vand containing threaded opening 3S which cooperatesv with the locking means 23. Such rib and islandconguration adds strength and rigidity to thehanger bracket and particularly reinforces the inclined arm portion -47 which offsets the main body and cross-arm assembly 50.

Thecross-arm-assembly 56 includes, as its lname Virnplies, a cross-arm member 5S pivotally attached at its midpoint to thehanger bracket finger portion 48 by a single central rivet 516 or other suitable connecting device. The cross-arm 55 is preferably offset centrally to receive the extending linger portion 48 of the hanger bracket and provides, adjacent its opposite ends, a pair of

coplanar end portions

57, 57 adapted each to support a rotatable roller wheel 6i). The Wheels Sli are preferably made of nylon or a similar substance having good wearability and configured especially to engage and roll along a bottom rail trough portion 61 of the overhead track member 14. This provides a rolling or movable support connection between the overhead track and the door 10, as desired. To prevent violent or extreme pivotal activity of the cross-arm assembly 55 about its pivot 56, a'pair of projecting

buttons

62, 62 are provided, one extending outwardly of each cross-arm end portion 57, to engagethe upper end'63 of the hanger brackets aangaat inclined arm portion 47. Location of the

buttons

62, 62 is selected to provide a desired rotational tilting or :Boating action for the cross-arm of less than 360 rotation.

To hold the hanger bracket 21 in its desired assembled relationship with the mounting bracket 20, the locking screw means 23 is employed; such being riveted over at its inner end "65 (see FIG. 4) behind the island section 52, thereby preventing its dissociation from hanger bracket 21 while providing threaded movement along the threaded opening 35. Clockwise rotation of screw means 2'3 serves to draw the raised island portion 52 tightly against the opposing inside face 68 of the mounting bracket, frictionally locking the hanger and mounting bracket together, pressing opposing facial areas of said two brackets against the adjustment means 22 to lock the latter as Well. Conversely, unthreading screw means 23 releases the two brackets and adjustment means when it is desired to adjust the hanger bracket and rollers 6i) relative to the mounting bracket.

The adjustment means 22 in the preferred form of hanger assembly illustrated in FIG. 2 comprises a substantially cylindrical disc of nylon or like material capable of being machined or moulded and having features of good wearability and a coecient of friction suicient to prevent its free rotation over the adjacent contacted surfaces and opposing areas of the

brackets

20 and 21 between which it is mounted. While the formation of the adjustment means 22 is generally disc-like, a cylindrical eccentric pin portion 70 projects from the rearward face 71 of its main cylindrical body portion 72. This projecting pin 70 is adapted to enter and cooperate with the elongated transverse opening 46 of the hanger bracket; and to that end is disposed off-center, or eccentrically, with respect to the central axis of the body portion 72. It will be recalled that the projecting head end 40 of the adjustment means extends, from the frontal face of the body portion 72, into opening 38 formed in the mounting brackets central platform portion 27. Rotation of the body portion 72, effected by engaging slot 41 of head portion 40 with a screwdriver or the like, results in the rectilinear-4 reciprocating displacement of the hanger bracket as the pin follows a circular path according to familiar principles.

Due to the frictional interference of the projecting member 7u and the sidewalls of the slotted opening 46, however, as well as the interfacial engagement between adjustment means 22 and adjacent bracket faces, free rotation of the adjustment means is deterred. This is particularly true when the load of the door is on the hanger assembly. Therefore the eccentric may readily be rotated to an infinite number of adjustment positions to correspondingly adjust the position of the hanger bracket and rollers 69 relative to the mounting bracket, as selected. Thereafter the locking means 23 may be operated to maintain the adjusted position of the hanger and mounting brackets. Thus the door 19, equipped with two assemblies 12, 12', may be plumbed and aligned in the doorway opening in an easy, convenient, and improved manner by adjusting either or both assemblies 12, 12' as needed.

Turning now to the modified hanger assembly 79 illustrated in FIGS. 7-9 of the drawings, it will be recognized that such is generally simplified over assembly 12 above described, yet without loss or sacrifice of the essential and desirable features of this invention. For instance, assembly 79 does not employ the particular locking screw means 23 of assembly 12, yet the necessary lock ing function is provided for in assembly 79. Also, the dual rollers 60, 69 and related cross-arm 50 have been removed from assembly 79; the same being replaced with a single, track-engaging roller means. With few exceptions, assembly 79 otherwise closely parallels the .elements and features of hanger assembly 12.l

Mounting bracket 86, like bracket 20 of assembly 12,

is preferably stamped of metal to provide a pair of coplanar aligned lateral mounting flanges 85, flanking a central body portion 86. The body portion 86 is set out of the plane of the flanges by transversely related interconnecting wall portions 87, 87 (shown in crosssection in FIG, 6), each llanked at their opposite endsby short ear extensions of the mounting arms, indicated at 88 and 88a. These extensions provide guideways tov pilot the hanger bracket 81 as the latter rectilinearlyf reciprocates between walls 87.

Mounting

flanges

85, 85 are each suitably provided-` with a central opening receptive of fastening means such as screw means 83, whereby the bracket 8l) is easily attached to one face of door 10 adjacent an upper corner thereof, as in assembly 12 of FIG. l. The body portion 86 is provided with a central circular-v opening S9 through which a circular head portion 90 of the adjustment means 82 extends. In this regard such body portion is adapted to superpose a portion of the hanger bracket 81 as the latter reciprocates in response to operation of the adjustment means.

The hanger bracket, as seen best in FIGS. 6 and 7, is formed with the generally rectangular body portion 91 which is adapted to be positioned upright in operating assembly between

walls

87, 87 and the guide ears 88, 83a of the mounting bracket. An elongated oval opening 92 is provided in body portion 91, symmetrical of the latters lengthwise axis and generally to one side (above) the midpoint thereof. Opening 92 further is aligned with its own lengthwise axis transverse to'the lengthwise axis of the hanger bracket, thereby to cooperate with adjustment means 82.

The body portion 91 is also angled inwardly at its upper end to provide an inclined arm portion 93, adapted to overhang the' upper end of door 10 in operation. The outer end of arm portion 93 is formed with an integral linger portion 94 extending in an offset plane paralleling the plane of body portion 91. Parallel raised

Vreinforcing ribs

95, 95 strengthen both

portions

93 and 94, with the latter serving to directly support a single rotatable track-v engaging roller means 96. To this latter end, roller 96 is rotatably carried on a rivet axle 97 tixed transversely to the bracket finger portion 94 (see FIG. 7). It will be understood that adjustment of the roller means toward and away from the upper end of door 10 depends on and occurs with the operation of adjustment means 82. to move the hanger bracket.

Adjustment means 82 is similar in all respects of structure and operation with adjustment means 22 of the previously descri-bed hanger assembly 12. Thus the same comprises a generally cylindrical form having a disclike body portion 99 from one end face of which eX- tends the coaxially aligned head portion 90. An eccentrically disposed pin portion 100 projects from the opposite end face of the body portion and is received in the elongated opening 92 of the hanger bracket. This arrangement serves to produce rectilinear reciprocating movement of the hanger bracket in response to rotation of the adjustment means; head portion 90 of the latter having a slot 101 receptive of a screwdriver blade for the purpose of engaging and rotating the adjustment means. Thereafter operation of locking means 83 maintains a desired adjusted position for the

brackets

80 and 81.

More particularly, the locking means 83 operates in the manner illustrated in FIGS. 8 and 9 to hold the assembly in operating position and selectively lock the adfi1stn1-entf meansY and? bracketstogeth'en Asf therein shown; screwJ means@ 83;' 835 are; threaded into the` door s tbermounting bracketand'v-the body portion 99-of the adjustment'means; Asfshownvin FIG.- 8, walls'87A in` tentionallyare of'insucient depth or dimension to permitfface- 162 ofthe mounting flanges S5 to lie iiush with face 163 of the hanger bracket when the adjustment meansgparticularl'y body portion 99Ythereof, is'assembled between the two brackets."
