Referring now to FIGS. 7 through 14 of the drawings, there is illustrated a modification wherein the numeral 75 indicates a sliding door and the numeral 76 indicates a horizontally disposed stationary track which may be supported on a member or surface such as the floor surface 77, FIG. 9. As shown in the drawings, the sliding door 75 includes a horizontally disposed bottom rail 78 as well as upstanding spaced apart side members '79, and the bottom rail 78 has a generally U shape and consists of spaced parallel vertically disposed sidewalls 80, as well as a horizontally disposed top portion or top wall 81, and the upper portions 82 of the sidewalls 34 are turned inwardly as at 63 so as to define or provide a grooved space for receiving therein thelower edge portion of a transparent panel or pane 8 The numeral 85 indicates a portion of the top wall 81 which is struck downwardly or offset downwardly so as to define or provide a stop member for a purpose to be later described.

The numeral 86 indicates diametrically opposed ribs which are substantially triangular in cross section, and the ribs 86 are integral with the inner surfaces of the sidewalls 80.

The numeral 87 indicates a base element or casting which is adjustably positioned between the sidewalls 8t), and the base element 87 includes a main body portion 83, FIG. 12, and there is provided diametrically opposed lugs 89 on the main body portion 88, and the lugs 89 are arranged below the ribs 86. Flanges 96 are arranged on the upper portion of the base element 87, and the flanges 96 are adapted to have a smooth or flat upper surface 91 for engaging the lower surface of the top wall 81, and there is defined or provided in the upper portion of the base element 87 a rounded smooth bore 92;, and the numeral 93 indicates a screw member which has an enlarged head 94 on one end thereof. The screw member 93 includes a threaded shank 95 which is adapted to engage the bore 92 as shown in FIG. 14 so that the screw member can cut or form its own threads in the bore 92, as for example, when the screw member 93 is properly turned or rotated, for example by means of a screwdriver engaging the kerf or slot in the head 94. The lower portion of the base element 87 is provided with arcuate surfaces or portions 96 which define or provide therebetween a generally rounded passageway 9'7, and the numeral 98 indicates a screw element which embodies an enlarged head 99, and the screw element 98 also includes a threaded shank 100 which is adapted to have a fastener or nut 101 arranged in threaded engagement therewith.

The numeral 102 indicates a support member which includes a pair of spaced parallel vertically disposed side sections or walls 163, and the support member 102 is pivoted or hingedly connected to the base element 87 as for example by means of a pivot pin 164. The support member 102 includes a wall piece 105 which has an aperture or opening 106 therein, and the shank 100 of the screw element 98 extends through the aperture 106. The numeral 167 indicates a roller which is journaled between the side sections 103 as at 168, and the roller 107 is adapted to engage the stationary track 76.

It will therefore be seen that according to the present invention there has been provided a corner adjustable roller assembly which is an improvement over prior similar devices such as that shown and described in prior Patent No. 3,040,391 and application Serial No. 18,352, filed March 29, 1960, and now abandoned.

With particular reference to the form of the invention shown in FIGS. 1 through 6, it will be seen that a pair of the adjustable roller assemblies 37 are adapted to be mounted in the lower corner portions of each door or sliding member 29 so that the member 20 can readily move back and forth along a stationary track such as the track 21.

It is to be noted that each of the adjustable roller assemblies 37 includes the bracket 38 which consists of the upstanding portion 50 that fits snugly within the lower portion of a side member 22, and each bracket 38 further includes a horizontal portion 39 which fits in an adjacent corner portion of the bottom rail 23. Thus, when an adjustable roller assembly 37 is mounted in place as shown in FIG. 1 or 2 for example, the portion 40 coincides with the mitered corner joint 36 so that in effect the bracket or adjustable roller assembly serves to interconnect or join the side rail and side members together when such a mitered corner joint is used. In addition an assembly 37 provides an adjustable support for the roller 62 as previously stated. Thus, the roller 62 is journaled between the sides 58 of the support member 55 by means of the shaft or pin 63, and by inserting the tip of a tool such as a screwdriver in through the access opening 68 and engaging the tip of the tool with the kerf 69 of the head 67 of the screw member 64, the screw member 64 can be rotated, and by rotating the screw member 64 in the proper direction, the inner end of the screw member 64 can be moved towards or away from the leg 51 so that the adjusted or pivotal position of the support member 55 can be regulated or changed as desired or required. Thus, this adjustment of the screw member 64 provides a means for shifting the position of the support member 55 and roller 62 relative to the stationary bracket 38 and by adjusting the roller 62 to different positions as desired or required a door such as the door 20 shown in FIG. 6 can be raised or lowered slightly in order to make sure that the door snugly and properly fits within its frame 71. Thus, the door 20 can be adjusted so that its top portion 110 is snugly engaged with the top portion 72 of the door frame 71.

The recesses 53 and 60 and 61 provide sufficient clearance so as to permit the necessary or desired adjustment of the support member 55 to readily take place in the previously described fashion or manner.

The flanges such as the flanges 48, 43, 44 and 52 are adapted to abut or engage inwardly directed shoulders such as the shoulders 45 and 46 on the frame work of the door whereby the bracket or associated parts will be properly maintained immobile in place in the corner of the door.

With further reference to the modification of FIGS. 7 through 14, the door '75 may have butt joints 111 instead of mitered joints, and the numeral 112 indicates the ad justable roller assembly which is adapted to be arranged contiguous to each lower corner of a door such as the door 75. It will be seen that by properly rotating the screw 93, as for example by inserting the tip of a screwdriver blade in the kerf of the head M, the base element 87 can be shifted or adjusted back and forth in the bottom rail 78 so that the base element 87 and support member 162 and roller 107 can be positioned at any desired location desired or required. The screw member 93 is adapted to have its threaded shank 95 arranged in engagement with the bore 92 of the base element 87 and the threaded shank 955 is adapted to form or make its own screw threads in the smooth bore 92, as for example as shown in FIG. 14. Furthermore, by rotating the screw member 93 in one direction, the base element 37 can be moved in one direction such as to the left in FIG. 8, and by rotating the screw member 93 in the opposite direction, the base element 8'7 can be adjusted or moved in the opposite direction such as to the right in FIG. 8.

It will also be noted that the support member 102 can be pivoted to different positions so that the relative positions of the wheel or roller 167 can be adjusted as desired or required, and this is brought about by adjusting or turning the screw element 98. The access opening 113: in the lower outer portion of the side member 79 is adapted to be used for permitting the insertion therethrough of a screwdriver blade in order to engage the kerf or slot in the head d9 of the screw element 98 so that the screw element 98 can be turned order to cause pivotal movement of the support member 162 on its pivot axis or pin 104. This pivotal movement of the support member 192 causes corresponding movement of the roller 1437 so that for example the etlective height of the door 75 can be raised or lowered or changed as desired in order for example to permit a door to be snugly and properly mounted within its frame such as in a frame similar to that frame shown in FIG. 6.

The portion 85 which is struck downwardly from the top wall 81 defines or provides a stop for limiting outward movement of the base element 87, as for example when the base element 87 is being adjusted or moved due to rotation of the screw member 93. it is to be noted that the support member 192 includes the wall piece M5 which has the aperture 196 therein for the projection therethrough of the shank of the screw element 98, and this shank 160 in cooperation With the nut or fastener 101 serves to insure that the support member 102 will properly pivot on its pin 1% as the screw element 98 is turned or rotated.

The base element 87 includes the opposed lugs 89 as well as the flanges 99 which have a configuration that snugly conforms to certain internal parts or surfaces of the bottom rail 78, as for example as shown in FIG. 9, whereby as the screw member $3 is rotated, the base element 87 will be properly guided and maintained in its proper aligned position as it is adjusted back and forth, and this adjustment of the base element permits the adjustable roller assembly to be located at the most advantageous position for supporting the sliding door so as to permit the door to properly slide back and forth on a track such as the stationary track 76.

It will be seen that according to the present invention there has been provided a fixture or device which is adapted to be used for fastening together the vertically disposed and horizontally disposed frame pieces of a unit such as a sliding door, and wherein the fixture also simultaneously serves as a mounting bracket for the roller and wherein there is provided a means for adjusting the roller. In the form of the invention shown in FIGS. 1 through 6, a miter joint is illustrated, whereas in FIGS. 7 through 14 a butt joint is illustrated. The present invention is thus a dual purpose unit and wherein the one unit or corner adjustable roller assembly serves to connect the horizontal and vertical pieces together and also provides an adjustable supporting means for the roller which engages the stationary track.

The mitered corner adjustable roller assembly of FIGS. 1 through 6 is adapted to be used with aluminum extruded members. FIGS. 1 through 6 illustrate the mitered corner adjustable assembly, and FIGS. 7 through 14 illustrate the dove-tail fit adjustable roller assembly which requires no screws or other hardware to securely house in the bottom rail, and the dove-tail fit is an important feature of the present invention. It is also an important aspect or feature of the present invention that thistadjustable roller assembly adjusts on the principle of tension on the screw rather than compression, so that there is a wedge action by a larger screw on the top and this permits use of a much lighter screw and wherein there is provided a wider range of adjustment.

Thus, according to the present invention, there is provided in combination with a movable door and a track there-below, an adjustable roller assembly that is arranged contiguous to each lower corner portion of the door, and wherein the roller assembly incorporates and provides both an adjustment and a structural corner bracket all in the same device, the roller assembly including a bracket which has a support member pivotally connected thereto, and wherein there is provided a screw means for adjusting the support member, and wherein there is provided access openings for gaining access to the screw means.

With further reference to FIG. 8 for example, the device can be staked as at and this eliminates the necessity of using additional hardware or fasteners. Also, it is only necessary to stake on one side, and when the vertical member is brought inte position, theone screw that holds the corner together also anchors the adjustable roller assembly in place so that the one screw does the entire job and this is an important feature or aspect of the present invention. The FIG. 8 assembly is also used as a corner unit, and the assembly of FIG. 8 can be an extrusion, stamping, or casting and is made so that the necessity of a lot of machining is eliminated.

With reference to the miter joint, this unit not only holds the corner together but also aligns the members at With the present invention there is provided a corner bracket assembly wherein there is utilized an extrusion or casting and with the present invention it is not necessary to do a lot of machining.

As to FIG. 2, the device holds the corner together and holds the horizontally disposed and vertically disposed members in alignment.

In FIG. 12 there is a dove-tail fit, or a T-slot arrangement can be used, and the members can be of different shapes as desired or required. Instead of the dove-tail fit, a rectangular fit can be utilized.

Minor changes in shape, size and rearrangement of details coming within the field of invention claimed may be resorted to in actual practice, if desired.
