Definitions

  • the present invention relates generally to roller shades having flexible shade fabrics, and more particularly to a hembar adapted for attachment to a lower end of a shade fabric.
  • Roller shades include a flexible shade fabric supported by an elongated roller tube for winding and unwinding of the shade fabric.
  • a hembar is attached to a lower end of the shade fabric to weight the lower end of the shade fabric. The weighting of the shade fabric by the hembar limits wrinkling of the shade fabric to facilitate smooth operation of the roller shade as the shade fabric is wound and unwound.
  • a variety of attachment means are used to secure shade fabrics to hembars including the use of adhesives and staples. It is also known to secure shade fabrics to hembars using elongated splines received in channels defined by the hembar.
  • a prior art hembar 2 including elongated splines 6 received in spline channels 4 of the hembar 2 to secure a flexible shade fabric 8 to the hembar 2.
  • the spline 6 is received in the spline channel 4 within a looped portion of the shade fabric 8, which is also received in the spline channel 4.
  • the spline 6 and the spline channel 4 are dimensioned such that the receipt of the spline 6 within the looped portion of the shade fabric 8 secures the shade fabric 8 to the hembar 2.
  • the shade fabric 8 covers an interior- facing side of the hembar 2. As shown, an exterior-facing side of the hembar remains uncovered by the shade fabric 8.
  • the hembar 2 shown in Figure 1 is made from an extruded plastic material and includes end caps 9 received in opposite ends of the hembar 2.
  • Roller shades are often used with blackout side rails to eliminate light gaps along opposite sides of the shade fabric.
  • the blackout side rails define vertical channels that receive side edge portions of the shade fabric.
  • the channels of the blackout side must be narrow in width, i.e., narrow in dimension perpendicular to the shade fabric, for example, approximately 0.5 inch in width.
  • prior art hembars utilizing spline-attachment means, such as hembar 2 are not usable with blackout side rails because the hembars will not fit within the narrow channels of the blackout side rails.
  • the typical prior art hembar 2 has a width of approximately 0.6 inch in width.
  • a hembar includes a front wall defining a substantially vertical front surface, a rear wall defining a substantially vertical rear surface opposite the front wall, and at least one spline channel between the front and rear walls.
  • the front and rear walls are spaced from each other by a horizontal distance and the spline channel is oriented at an oblique angle with respect to a vertical line such that a width of the spline channel is greater than the horizontal distance between the front and rear walls.
  • the oblique orientation of the spline channel instead of perpendicular to the vertical line, provides for reduction in the hembar dimensions without reduction of the spline dimensions to facilitate receipt of the hembar in blackout side rails having correspondingly narrow vertical channels.
  • the hembar includes top and bottom spline channels.
  • Each of the top and bottom spline channels is preferably oriented with respect to the front wall such that the channel is concealed from view when the hembar is viewed from any location in front of the hembar.
  • each of the spline channels defines a longitudinally-extending slot opening for receiving a looped portion of a shade fabric within the interior of the channel and an open end for receiving a spline.
  • Each spline channel may also define a notch in a wall opposite the slot opening of the channel for receiving part of the looped portion of the shade fabric to facilitate insertion of the spline.
  • the hembar includes a longitudinally-extending retainer pocket between the front wall and the rear wall adapted to receive a weighting element.
  • the retainer pocket is adapted to receive the weighting element in an off- centered manner such that the weighting element is located closer to the rear wall than to the front wall.
  • a hembar support member includes at least one obliquely oriented support surface for receiving either a front wall or a rear wall of the hembar and supporting the hembar such that one of the spline channels is oriented horizontally.
  • the method includes the steps of placing the hembar on the hembar support member such that the bottom spline channel is substantially horizontal, directing a shade fabric into the bottom spline channel to define a looped portion and inserting a spline into the bottom spline channel to secure the shade fabric to the hembar body in the bottom channel.
  • the method includes the steps of wrapping the shade fabric between the channels to cover the front wall, placing the hembar body on the hembar support member such that the top spline channel is horizontal, directing shade fabric into the top spline channel to define a looped portion, and inserting a spline into the top spline channel to secure the shade fabric to the hembar body in the top spline channel.
  • the shade fabric is directed into the channels using a creasing tool and the splines are inserted into the channels using a spline tool having a fabric-engaging portion including a tapered flange and a post adapted for receipt in an opening defined by each spline for applying a pulling force to the spline.
  • the method may also include the step of wrapping the shade fabric between the spline channels to cover the rear wall of the hembar body so as to provide a full wrap of the hembar body.
  • the wrapping the rear wall by the shade fabric may occur prior to the wrapping of the front wall.
  • the method further comprises the removing the spline from the top spline channel, directing the shade fabric into the top spline channel such that two looped portions of the shade fabric are defined and arranged in a stacked fashion within the top spline channel, and re-inserting the spline into the top spline channel within the two looped portions of the shade fabric such that the shade fabric is secured to the hembar body in the top spline channel.
  • the steps of directing a shade fabric into one of the spline channels and inserting a spline into the spline channel may be performed in a two-step procedure that is performed over a length of the hembar body and repeated to advance the spline from a first end of the hembar body to an opposite second end of the hembar body.
  • Figure 1 is a perspective view of a prior art hembar attached to a shade fabric.
  • Figure 2 is a cross-sectional view of a hembar according to an exemplary embodiment of the invention.
  • Figure 3 A is a perspective view comparing a hembar according to the present invention with a prior art hembar, the hembars secured to shade fabrics and shown from a front side of the hembars.
  • Figure 3B is a perspective view of the hembars and shade fabrics of Figure 3 A shown from a rear side of the hembars.
  • Figure 4 is a perspective view of a hembar according to the present invention secured to a shade fabric using a full wrap option.
  • Figure 5 is a perspective view of the hembar and shade fabric of Figure 4 during assembly, the hembar supported on a hembar support having obliquely-oriented support surfaces, shown with a creasing tool being used to direct a looped portion of the shade fabric into a bottom spline-receipt channels.
  • Figure 6 is a perspective view of the hembar and shade fabric of Figure 5 shown with a spline tool being directed into the looped portion of the shade fabric from an open end of the hembar body.
  • Figure 7 is a perspective view of the hembar and shade fabric of Figure 6 shown with a spline attached to the spline tool being pulled into the bottom spline-receipt channel within the looped portion of the shade fabric.

  • Figure 9 is a perspective view of the spline tool of Figures 6 and 7.
  • Figure 10 is a perspective view of an alternative spline tool.
  • Figure 11 is a perspective view of the creasing tool of Figures 5 and 8.
  • hembar 10 is illustrated in the cross-sectional view of Figure 2 a hembar 10 according to an exemplary embodiment of the present invention.
  • the hembar 10 is configured to define a narrowed cross section allowing receipt of the hembar 10 within blackout side rails having correspondingly narrow vertical channels to facilitate limited light leakage.
  • the hembar 10 includes an elongated body 12 including a front wall 14, an opposite rear wall 16, a top 18 and a bottom 20.
  • the front and rear walls 14, 16 respectively define front and rear surfaces that are substantially vertical when the hembar is oriented as shown in Figure 2.
  • the orientation of Figure 2 represents the substantially vertical orientation for the hembar when it is attached to a lower end of a suspended shade fabric.
  • the hembar body 12 is preferably made from an extruded material such as aluminum or plastic. The invention, however, is not limited to any particular material.
  • the hembar 10 includes top and bottom channels 22, 24 extending along the length of the hembar body 12 and located between the front wall 14 and the rear wall 16 adjacent the top 18 and the bottom 20, respectively, of body 12.
  • the channels 22, 24 are used to attach a shade fabric 28 (see Figure 4) to the hembar and, therefore, may hereinafter be referred to as "fabric attachment channels”.
  • fabric attachment channels As also described below, the desired attachment between the hembar and a shade fabric is provided by elongated splines 26 ( Figure 4) received in the channels 22, 24.
  • the channels 22, 24 may also hereinafter be referred to as “spline-receipt channels” or “spline channels”.
  • the front and rear walls 14, 16 of hembar body 12 are spaced from each other by a horizontal distance, H.
  • the spline channels 22, 24, defined between the front and rear walls 14, 16 and having a width, W (e.g., approximately 0.35 inch), are not horizontal like the spline channels 4 of prior art hembar 2. Instead, as shown in Figure 2, the spline channels 22, 24 are oriented obliquely to a vertical line, V. As a result of the oblique orientation, the width W for the spline channels 22, 24 is greater than the horizontal distance, H, between the front and rear walls 14, 16.
  • obliquely orienting the spline channels 22, 24 in this manner allows for a reduction in the overall width of the hembar body 12 (i.e., horizontal distance between the front and rear surfaces defined by walls 14, 16) without a corresponding reduction in dimensions for splines received in the spline channels 22, 24.
  • This feature desirably facilitates use of the hembar 10 in blackout side rails having correspondingly narrow vertical channels.
  • the splines 26 are received in the channels 22, 24 within looped portions of the shade fabric 28.
  • the respective widths of the spline 26 and the spline-receipt channels 22, 24 permit the splines 26 to be pulled into the spline-receipt channels 22, 24 within the looped portion of the shade fabric 28 through one of opposite open ends defined by hembar body 12.
  • the relative widths are preferably selected such that the receipt of the spline 26 wedgingly compresses the shade fabric 28 along opposite sides of the spline 26. Such wedging receipt of the spline 26 firmly secures the shade fabric 28 to the hembar 10 within the spline-receipt channels 22, 24.
  • the spline-receipt channels 22, 24 are respectively located adjacent the top and bottom 18, 20 of the hembar body 12.
  • This construction provides for alternative wrapping options including a half-wrap option and a full-wrap option.
  • the half- wrap option shown in Figures 3 A and 3B, looped portions of the shade fabric 28 are secured within each of the spline-receipt channels 22, 24 and an intermediately located portion of the shade fabric 28 extends between the spline-receipt channels 22, 24 along the front wall 14 of the hembar body 12.
  • the rear wall 16 of the hembar body 12 remains uncovered by the shade fabric 28 in the half- wrap option.
  • the full wrap option is shown in Figure 4.
  • both the front wall 14 and the rear wall 16 of the hembar body 12 are covered by the shade fabric 28 in the full-wrap option.
  • the full wrap option is described in greater detail below.
  • the front and rear walls 14, 16 of the hembar body 12 will respectively define interior- facing and exterior- facing sides of the hembar 10 when an associated shade is installed within a building, for example, to shade a window.
  • the hembar 10 of the present invention can be compared to the prior art hembar 2 of Figure 1.
  • the spline-receipt channels 22, 24 of hembar 10 are dimensioned to receive splines 26 substantially similar (i.e., having approximately similar dimensions) as the splines 6 received in the spline-receipt channels 4 of hembar 2.
  • the splines 6 and 26 should function in similar fashion to provide similar attachment characteristics (i.e., similar wedging action) assuming other factors such as material properties are equivalent.
  • the orientation of the similarly-sized splines 6 and 26 to their respective hembars 2, 10 is not similar.
  • the change in the orientation of the spline 26 allows the front and rear walls 14, 16 of hembar 10 to be spaced more closely to each other than the front and rear walls of the prior art hembar 2 while still accommodating an appropriately sized channel between the walls 14, 16 receiving the similarly sized spline 26.
  • This reduction in the distance between the front and rear walls 14, 16 reduces the overall thickness or profile of the hembar 10 as compared to that of hembar 2.
  • the width of the hembar 10 i.e., the distance between the front and rear walls 14, 16 of hembar body 12
  • the width of the hembar 10 is approximately 0.4 inch or less.
  • the reduction in the overall thickness of the hembar 10 provides for the desired receipt of the hembar 10 within blackout side rails having correspondingly narrow vertical channels (i.e., approximately 0.5 inch wide) that are too narrow to accommodate prior art hembar 2 (i.e., approximately 0.6 inch wide).
  • the hembar 10 of the present invention is shown in cross section without splines 26 and an attached shade fabric 28 to facilitate illustration of the hembar.

  • the splines 26 used with hembar 10 will function to secure a shade fabric to the hembar 10 in a similar fashion as the splines 6 used with the prior art hembar 2 (i.e., there will be no reduction in the clamping action provided by the splines).
