Description

STRUCTURAL DEVICE; Filed April 15, 1961 INVENTOR. PAUL H. 5L OAN A TTOPNEFS rates This invention relates in general to a carrier structure supportable upon a track and, more particularly, to a type thereof including a roller engageable with a pair of spaced, parallel rails on said track and hanger means extending downwardly between said rails for supporting a panel.

For many years there has been widespread use of traverse rod assemblies including a track and a plurality of sliders or carriers mounted upon the track. In many cases, cable means have been connected to one or more of said carriers for effecting movement of a panel supported upon and suspended from said carriers. In general, these traverse assemblies are used to support panels both for decorative purposes and as an effective closure means.

It is well known that the existing carriers, by means of which the panels have previously beensupported upon and moved along the track, have long been the source of many problems. That is the carrier should have sufficiently low frictional characteristics with respect to the track as to enable an operator to effect the desired movement with a minimum of force applied thereto and yet they must also engage the track sufficiently snugly that they will be held firmly therein and will not twist or jam within or on the track structure. Further, the hangers must be inexpensive and yet sturdy, and they must be easy to handle, particularly in their installation into the track. These several, often conflicting, requirements have in the past presented a variety of diihculties in connectionwith the provision of traverse rod supported draperyand it has in the past often been necessary to sacrifice one or more of the above-named desired features in order to obtain others of such features.

In view of the development of the present invention to meeting a specific problem in connection with the supporting of draperies from traverse rods, specific reference is made herein to the use and operation of the carrier structure in connection with a panel supporting traverse, which traverse assembly may be cable operated or manually operated. However, it will be recognized that such specific reference is for illustrative purposes only and that the invention will be applicable to other uses of a similar nature.

Accordingly, a primary object of this invention has been the provision of a carrier construction capable of supporting a panel upon the track of a traverse assembly wherein said carrier is capable of movement along the track with a minimum of force being applied thereto in the direction of such movement and wherein said carrier is arranged and constructed so that the panel engaging hanger thereon is held against substantial movement transversely of the supporting track.

A further object of this invention has been the provision of a carrier structure, as aforesaid, which is relatively inexpensive to manufacture, which can be easily and. quickly connected to flexible panels, which requires little or no maintenance, ,whichcan be used more effectively and efilciently than most existing carriers for the same or similar purposes, which is easy to install, which is substantially foolproof in operation, which will not jamb in, or pivot excessively with respect to, the track which supports it, and which when panel traversing cables are used, is operable with a type of track configuration 3,@?,Z22 Patented Feic. 5., 1953 wherein the carriers cannot interfere with, or be obstructed in their movement by such cables.

General Description ing. A roller having a pair of spaced annular external flangesextending radially outwardly from the peripheral surface thereof is disposed within the cylindrical opening so that the opposite axial ends or" the roller project outwardly through the opposite sides of the body mem her. The body member is provided with internal annular flangemeans which extend into said cylindrical opening on opposite sides of said external annular flanges which are disposed therebetween. A plurality of bearing balls are disposed Within the annular groove defined between the annular flanges for rotatably supporting the roller within the body member.

The carrier is supportable upon a track having span of spaced, parallel rails which are engaged by the op posite 'end portions of the roller. The hanger element extends between the rails, and guide means on the body member cooperates with the roller to engage the track and thereby prevent excessive pivoting of the body memher and hanger with respect to the track.

Detailed Construction substantially vertical central wall 16 which serves as the front wall of the rear passageway 12 and the rear wall of the front passageway 13. The rear passageway 12.

has an upper wall 17 which is preferably substantially coplanar with, and an extension of, the upper wall 18 of the front passageway. The rear passageway 12 has a bottom wall 19 and a pair of preferably coplanar and substantially

vertical flanges

22 and 23 which extend downwardly and upwardly, respectively, from the rearward edges of the upper wall 17 and bottom wall 19 toward each other to define the slot 24- which communicates with-the rear side of the passageway 12 and extends lengthwise thereof. The

flanges

22 and 23 serve as guide rails in a manner discussed hereinafter.

The front passageway 13 (FIGURE 2) has a front wall 26 extending downwardly from the front edge of the upper wall 13 and a pair of preferably coplanar and substantially horizontal flanges 2'7 and 28 which are integral with and extend toward each other from the lower edge of the front wall 26 and an opposing portion of the front side of the central wall 16. The flanges 27 and 28 define a slot 29 which communicates with the lower side of the front passageway 13 throughout its length. The upper wall 13 of the front passageway 13 has in its upper surface an undercut recess 32 which extends lengthwise thereof. The upper Wall 17 has a lip 33 which projects beyond the flange 22 and extends lengthwise of the track. The lip 33 and recess 32 are provided for mounting the track by means not shown.

It will be apparent that the carrier 10 can be utilized with other types of track configurations, but the above disclosed track II has been found to be satisfactory for this purpose. The track may be fabricated from any convenient material such as metal or plastics.

The carrier 19 (FIGURES 2, 3 and 4) in its preferred form is comprised of a relatively flat, substantially circular body member 36, which has a centrally located and relatively large, cylindrical opening 37 extending coaxially therethrough. A substantially flat hanger element 38 is preferably integral with the body member 36 and extends radially therefrom approximately midway between the axial ends thereof. The body member 36 and hanger element 38 are preferably fabricated from a plastic material such as nylon.

The body member 36 (FIGURE 4) has an integral, annular flange 39 adjacent one axial end thereof which extends radially inwardly a slight distance from the wall 40 defining the cylindrical opening 37. The body member 36 also has an annular flange 42 which projects axially from the other axial end of the body member concentric with and adjacent to said cylindrical opening 37. During assembly of the carrier 19, the flange 42 is spun, pressed or,otherwise moved fro-m its axially extending position of FIGURE into its radially inwardly extending position of FIGURE 4, Where it has about the same internal diameter as the flange 39.

The extended end of the hanger element 33 (FIGURES 3 and 4) has a pin opening 43, the central axis of which extends in the same direction as the cylindrical opening 37 for reception of a pin, such as the pin shown in broken lines at 44 in FIGURE. 1, for engaging a panel, such as the drape 45. The portions of the hanger element 38 adjacent the lower edge and side edges of the pin opening 43 may be strengthened by the integral, embossments 46 and 4-7 (FIGURE 4) on opposite sides of the hanger element 38.

The body member 36 (FIGURES 2 and 4) includes four

integral abutments

48, 49, 50 and 51 which are arranged in coaxial pairs and extending from the body member 36. That is, the

abutments

48 and 49 extend from one side of the body member 36 and the abutments 50 and 5f extend from the opposite side thereof. The

abutments

48, 49, 5t) and 51 define a plane which perpendicularly intersects the carrier adjacent the connection of the hanger element 33 with thebody member 36, said plane being spaced downwardly from the cylindrical opening 37 a distance slightly greater than the thickness of the flanges 27 and'ZS on the track 11.

A roller 55 (FIGURES 4 and'S) is rotatably disposed within the cylindrical opening 37 so that the

axial ends

56 and 57 thereof extend beyond the adjacent axial sides of the body member 36 (FIGURE 4). The roller 55 has a pair of spaced,

annular flanges

58 and 59 which extend radially outwardly from, and are integral with, the peripheral surface of the roller 55 near the center thereof. Said

flanges

58 and 59 are of diameter slightly less than the diameter of the cylindrical opening 37 and they define a groove 62 which is preferably located midway between the axial ends of the roller 55. The groove 62 is arranged to receive and snugly engage a plurality of bearing balls 63 which, when disposed within said groove 52, project slightly beyond the peripheral edges of the

flanges

58 and 59 for engagement with the wall 40 defining the cylindrical opening 37, whereby the roller 5'5 is rotatably supported Within and upon the body member 3d. The annular flanges 53 and 59 are disposed between, and in overlapping and sliding engagement with, the

annular flanges

39 and 42 on the body member 36, whereby material axial movement of the roller 55 with respect to the body member 36 is prevented.

The diameters of the

axial end portions

56 and 57 of the roller 55 are such that the distance between said

axial end portions

56 and 57 and the said plane defined by the upper edges of the abutments d8, 49, 50 and 51 is slightly greater than the thickness of the flanges 27 and 28 on the track 11. The width of the slot 29 is slightly greater than the thickness of the body member 36 adjacent said abutments. Accordingly, the body member 36 can be slidably disposed within the slot 29 when the ends of the roller 55 are engaging the upper surfaces of the flanges 27 and 28 and the abutments 4-3, 49, 5t) and 51 are disposed below said flanges 27 and 28. The central opening 64, which extends coaxially through the roller 55, reduces the weight thereof and materials therein.

Operation As indicated from the above description, the roller 55 (FIGURE 5) is assembled with the body member 36 by inserting the axial end 57 thereof through the cylindrical opening 37 and then through the annular flange 39 with the bearing balls 63 disposed in the groove 62. Thereafter, the annular flange 42 is turned from its axial position of FIGURE 5 into its position of FIGURE 4 so that it and the flange 39 overlap the

annular flanges

59 and 58 on the roller 55. The carrier it) is now ready for assembly with the track 11 by inserting the roller 55 into one end of the passageway 13 so that the

abutments

48, 49, 50 and 51 are disposed upon the lower sides of the flanges 27 and 28, and the hanger element 33 extends downwardly therefrom.

A panel 45 (FIGURE 1), such as a drape, is then mounted upon the hanger elements 38 by means, such as a pin 44 which can extend through the pin openings 43, for example, in the hanger elements 38.

The panel is then movable manually or by a suitable cable (not shownlin a conventional manner lengthwise of the flanges defining the slots 24 and 29 (FIGURE 1). The

abutments

48, 49, 50 and 51 on the carrier 10 prevent any material amount of pivotal movement by the carrier 10 around the axis of the roller 55 with respect to the track 11. Thus, said abutments prevent the hanger element 38 from swinging into the passageway 13, when the pin 44 is not applied to the hanger. The abutments also cooperate with the roller 55 to reduce materially the transverse movement of the hanger element 38 forwardly and rearwardly with respect to the track 11.

Although particular, preferred embodiments of the invention have been disclosed above for illustrative purposes, it will be recognized that variations or modificatlons of such disclosure, which come within the scope of the appended claims, are fully contemplated.
