Definitions

  • the present invention relates to an end cap for use on a rail for a window covering. More specifically, it relates to a removable end cap with a bias to ensure a tight fit against the end of the rail.
  • US 2006/196615 A describes cellular panels that may be suspended from head rails through the use of a rigid strip of material positioned with the cellular panel.
  • a securement insert is provided.
  • the securement insert includes a cap securable with the head rail by an interference fit and a slot member including a restricting member extending from the cap.
  • US 2014/158314 A describes skew adjustment method and apparatus for adjusting the skewed condition of a movable rail of a window covering in which the movable rail is supported by lift cords wrapped around spools.
  • a drive train disconnecting mechanism is used to disconnect a first spool from a second spool, the first spool is rotated relative to the second spool, thereby changing the length of the first lift cord relative to the second lift cord until the movable rail is in the desired position; and then the first and second spools are reconnected so the first and second spools rotate together.
  • An end cap may be used to enable multiple disassemblies and reassemblies of the end cap to access the skew adjustment mechanism.
  • US 2011/0315329 A describes a double winding device for a window shade including a head rail receiving first and second cord-winding seats.
  • First and second movable seats are movably mounted between the first and second elastic cord-winding seats and respectively include first and second pulley units.
  • a folding/unfolding cord is wound around the first and second pulley units and has two end sections extending through a bottom wall of the head rail and extending through two sides of a shade and fixed to a bottom of the shade.
  • the first and second elastic cord-winding seats respectively include first and second elastic cord-winding spools.
  • a first actuation cord is wound around the first elastic cord-winding spool and has a distal end fixed to the first movable seat.
  • a second actuation cord is wound around the second elastic cord-winding spool and has a distal end fixed to the second movable seat.
  • US 2015/0020982 A describes a handle which is releasably secured to a rail wall by means of fasteners extending from inside the rail.
  • An actuator shaft pushes against a contact plate to move a movable braking member to stop the rotation of a rod inside the rail.
  • an end cap mounting arrangement is provided with the end cap having an arcuate cross-sectional shape which is flattened when the end cap is installed, creating a bias, which results in a releasable, reusable end cap with a tight fit against the end of a rail.
  • Figure 1 shows a window covering 10 including a head rail 12, a pleated shade portion 14, an intermediate rail 16, a cellular shade portion 18, and a bottom rail 20.
  • Any one of the rails 12, 16, 20 may house components (not shown) to assist the user in raising or lowering the window covering 10.
  • the rails 12, 16, 20 are elongated and include end caps, such as the end cap 22 on the intermediate rail 16, which provide a pleasing, aesthetic finish to the rail 16, and provide access to any components housed in the rail 16 during assembly of the window covering 10 and also later on, during adjustment or replacement of the components housed in the rail 16.
  • end caps such as the end cap 22 on the intermediate rail 16
  • end caps such as the end cap 22 on the intermediate rail 16
  • FIG. 1 shows a window covering 10 including a head rail 12, a pleated shade portion 14, an intermediate rail 16, a cellular shade portion 18, and a bottom rail 20.
  • the rails 12, 16, 20 are elongated and include end caps, such as the end cap 22 on the intermediate rail 16, which provide a pleasing
  • Figures 2-11 show the end cap 22 and rail 16 of Figure 1 in more detail.
  • the rail 16 has a "U"-shaped profile including an elongated base wall 24 and two elongated legs 25 projecting away from the base wall 24.
  • the end of the rail 16 is flat, lying in a vertical plane.
  • Two opposed tracks 26 project away from the inner surface of the base wall 24. These tracks 26 extend parallel to the longitudinal axis of the rail 16 and are designed and sized to slidingly receive mating wings 28 on corresponding outriggers 30 projecting from the inner surface of the end cap 22.
  • the tracks 26 have a hook-shaped cross-section, projecting away from the base wall 24 and then inwardly, toward the central axis of the rail 16, forming a space 27 between the inwardly projecting portion and the base wall 24.
  • the mating wings 28 project outwardly, away from the central axis of the rail 16, and are received in the respective spaces 27 formed by the tracks 26.
  • the rail 16 also defines an opening 32 through the base wall 24 of the rail 16. The opening 32 is located between the tracks 26 near the end of the rail 16.
  • a beam 34 projects from the inner surface of the end cap 22 in a horizontal direction substantially parallel to the wings 28 (See also Figure 6 ).
  • a projection 36 extends from the free end of the beam 34 toward the base wall 24.
  • the projection 36 is sized and located such that it is received in the opening 32 in the rail 16 when the end cap 22 is snapped onto the rail 16, as described later.
  • the projection 36 defines a sloped leading surface 40 (See Figure 6 ) to ease the beam 34 onto the base wall 24 of the rail 16, and a slightly tapered shoulder 42 on the opposing surface of the projection 36 to pull the end cap 22 into the rail 16 and to lock the projection 36 into the opening 32 (See also Figures 4 and 5 ).
  • the end cap 22 also includes an inwardly-projecting, discontinuous flange 38 extending along substantially the entire perimeter of the end cap 22 and spaced inwardly a short distance from the perimeter.
  • This flange 38 fits inside the end of the rail 16, with the first and second opposed edges 48 and the third and fourth opposed edges 46, 46* of the end cap 22 abutting the end of the rail 16.
  • the flange 38 provides a light stop to prevent light from passing completely through any small gaps that may exist between the end cap 22 and the end of the rail 16.
  • the dotted vertical line 44 is perpendicular to the horizontal direction of the wings 28. It may be appreciated that the top edge 46 of the end cap 22 lies slightly forward of the dotted line 44, while the bottom edge 46* lies on the dotted line 44.
  • the top edge 46 of the end cap 22 impacts first against the end of the rail 16. The end cap 22 is then pushed further into the rail 16 until the projection 36 on the beam 34 snaps into the opening 32 in the base wall 24 of the rail 16, which also coincides with the position where the end cap 22 fits tightly against the rail 16, as shown in Figure 8 .
  • the wall 42 of the projection 36 abuts the wall of the opening 32, which is fixed relative to the rail 16, so the wall of the opening 32 serves as a retaining wall, providing a positive stop that prevents the end cap 22 from being pulled back out of the rail 16.
  • the scale is distorted and the distance that the end cap 22 is pushed into the rail 16 between Figures 7 and 8 is exaggerated to illustrate the point.
  • the wall 42 of the projection 36 is slightly tapered relative to the wall of the opening 32, so that the beam 34 pulls the end cap 22 further toward the rail 16 as the projection 36 moves further into the opening 32.
  • the end cap pivots about the top edge 46 relative to the rail 16. This causes the wings 28 to push upwardly against the bottom surface of their respective tracks 26, which are fixed relative to the rail 16, wedging the wings 28 against the tracks 26. Even though the actual horizontal distance traveled is small, it is enough to wedge the wings 28 against their corresponding tracks 26 for a tight fit between the end cap 22 and the rail 16 and creates a tension in the end cap 22 which retains the end cap 22 on the rail 16 (See Figure 8 ).
  • the beam 34 also exerts a downward force on the base wall 24 of the rail 16, which lifts the wings 28 upwardly against the tracks 26.
  • the dotted line 47 shows that, when at rest, the end cap 22 has a slightly arcuate shape.
  • the front and rear edges (first and second opposed edges) 48 of the end cap 22 are located slightly inwardly, away from the dotted line 47 and toward the rail 16, and the central portion of the end cap 22, located between the opposed edges 48, is located further away from the rail 16.
  • the edges 48 of the end cap 22 impact against the rail 16.
  • the projection 36 on the beam 34 riding on the base wall 24 of the rail 16 causes the beam 34 to flex upwardly.
  • the projection 36 on the beam 34 slides past the vertical edge of the opening 32 on the base wall 24 of the rail 16, the beam 34 snaps back downwardly, and the projection 36 abuts the edge of the opening 32 (the retaining wall), providing a positive stop that secures the projection 36 in the opening 32.
  • the beam 34 serves as a securement leg to keep the end cap 22 secured onto the rail 16 in a flattened condition.
  • the wings 28 wedged in the tracks 26 also are abutting surfaces fixed relative to the rail 16 (i.e.
  • FIG. 12 shows the projection 36 on the beam 34 abutting the edge of the opening 32, which serves as a retaining wall.
  • the user pushes upwardly on the projection 36 on the beam 34 until it clears the base wall 24 of the rail 16, and then grasps the end cap 22 and pulls outwardly. Once the projection 36 has cleared the opening 32, the end cap 22 may be pulled straight out. The end cap 22 may be reinstalled over and over again with no detrimental effect on its performance.
  • FIG. 13 An alternative embodiment, shown in Figure 13 , is the same as the embodiment described above except that, instead of the opening 32, there is a body 32* projecting upwardly from the base wall 24 of the rail 16 in the same position as the opening 32.
  • the body 32* has a vertical wall on an inner side, which is fixed relative to the rail 16 and serves as a retaining wall, such that, when the projection 36 passes over the body 32*, the projection 36 abuts the retaining wall on the body 32*, thereby having the same effect of providing a positive stop to secure the beam 34 in position on the rail 16.
  • body 32* in this embodiment is formed as part of the rail 16, it alternatively could be a separate member secured to the rail 16, in which case its retaining wall still would be fixed relative to the rail 16.
  • FIG. 14 Another alternative embodiment shown in Figure 14 includes a rail 16** which has a bump 32** (instead of an opening 32) formed on the base wall 24.
  • the projection 36 passes over the bump 32**, which is a body projecting from the rail that provides an abutting retaining wall which is at an angle to the vertical. This angled retaining wall also causes the projection 36 to pull the end cap inwardly, toward the rail as the projection 36 passes over the bump 32**.
  • Another alternative embodiment (not shown) is the same as the first embodiment except that it has no opening 32 or body 32* on the rail 16 but simply relies upon the wedging of the beam 34 pushing downwardly on the base wall 24 and of the wings 28 pushing upwardly on the tracks 26 to secure the end cap on the rail 16 against the biasing force of the flattened end cap 22 which wants to return to its arcuate shape.
  • This alternative embodiment has the advantage that no holes (such as the hole 32 of Figure 12 ) or discontinuities (such as the dimple 32* or 32** of Figures 13 and 14 respectively) are seen by the user on the rail 16.
  • Figures 15-23 show another embodiment of an end cap 22' and rail 16.
  • the rail 16 is identical to the rail 16 described above except that there is no need for an opening 32 or bump 32**.
  • the end cap 22' is similar to the end cap 22 of Figure 2 in that it has wings 28' distally mounted on outriggers 30'.
  • the outriggers 30' are not in contact with the end plate 22' but instead are cantilevered off of a beam 50 which is centrally connected along beam portions 52 to the end plate 22'. This allows the outriggers 30' to rotate slightly in the "z" direction (in the vertical direction, See Figure 15 ) relative to the beam 50 and relative to the end plate 22'.
  • the beam 50 pushes against the bottom of the rail 16 when the end cap 22' is installed on the rail 16, serving as a securement leg, and the outwardly projecting wings 28' are received in the spaces 27 formed between the tracks 26 and the bottom surface of the rail 16, so each of the wings 28' (together with its respective outrigger 30') also serves as a securement leg.
  • the wings 28' engage the tracks 26, the wings 28' are wedged against the tracks 26 and are squeezed together, toward each other, in a squeezing direction. Squeezing the wings 28' together in this particular geometry lifts the beam 50 and the end cap 22' relative to the base of the rail 16 (i.e. moves the end cap in a direction perpendicular to the squeezing direction).
  • the beam 50 has a tapered front edge 58, which eases the beam 50 into the inside of the rail 16.
  • the wings 28' are parallel to each other and are mirror images of each other. As shown in Figure 15 , the wings 28' are tapered in both the "x" and "z” directions, which helps the wings 28' enter into the spaces 27 beneath and between the tracks 26 and helps cause the deflection of the outriggers 30'. As shown in Figure 17 , the top surfaces of the wings 28' are at a lower elevation at the end directed toward the rail 16 and taper to a higher elevation at the end adjacent to the end cap 22'. As shown in Figure 15 , the outer surfaces of the wings 28' are closer together at the end directed toward the rail 16 and taper further outwardly in the "y" direction as they approach the end cap 22', which helps the wings 28' enter easily into the spaces 27 beneath and between the tracks 26.
  • the dotted vertical line 44 is perpendicular to the horizontal direction of the wings 28'. It may be appreciated that the top edge 46' of the end cap 22 lies slightly forward of the dotted line 44, while the bottom edge 46* lies on the dotted line 44.
  • the top edge 46' of the end cap 22' impacts first against the end of the rail 16, as shown in Figure 18 .
  • the end cap 22' is then pushed further into the rail 16 until the end cap 22' fits tightly against the rail 16, with all four edges of the end cap abutting the flat end of the rail, as shown in Figure 19 .
  • the end cap 22' pivots about the top edge 46' relative to the rail 16. This pivoting causes the wings 28' to wedge tightly into the space 27 between the tracks 26 and the rail 16 such that the end cap 22' is held snugly against the rail 16 and cannot accidentally be pried off.
  • the wings 28' serve as securement legs.
  • the dotted line 47 shows that, when at rest, the end cap 22' has a slightly arcuate shape.
  • the front and rear edges (first and second opposed edges) 48' of the end cap 22' are located slightly inwardly, away from the dotted line 47 and toward the rail 16, and the central portion of the end cap 22', located between the opposed edges 48', is located further away from the rail 16.
  • the front and rear edges 48' of the end cap 22' impact against the rail 16, as shown in Figure 21 .
  • Figure 23 is a section view along line 23-23 of Figure 16 , showing the end cap 22' mounted on the rail 16. It may be appreciated that there is a projection 54 adjacent the top edge 46' of the end cap 22', and intermediate the front and rear edges 48' of the end cap 22'. This projection 54 provides a support surface for an arcuate plate 56, which is wedged between the two elongated legs 25 of the rail 16 (See Figure 2 ) projecting away from the base wall 24 of the rail 16. This arcuate plate 56 spans the opening of the rail 16 so as to cover and hide any mechanism housed inside the rail 16.
  • Figures 24-30 show other embodiments of an end cap 22** which have a higher holding power than the end cap 22' described above, and in which the degree of holding power can be fine-tuned as desired. Comparing the end cap 22' of Figure 23 with the end cap 22** of Figures 24-27 (especially as seen in Figure 26 ), it may be appreciated that the beam 50**, outriggers 30** and wings 28** of this end cap 22** forms a more flattened-out, bow-shaped profile as compared with the "M" shaped profile formed by the beam 50, outriggers 30' and wings 28' of the previous end cap 22'. As in the previous embodiment, the outriggers 30** are cantilevered from the beam 50**, and the wings 28** are distally mounted on the outriggers 30**.
  • the end cap 22** moves toward the base of the rail 26 as the end cap 22** is installed onto the rail 26 and the wings 28** are squeezed together (again moving perpendicularly to the squeezing direction).
  • This causes the beam 50** to press against the base of the rail 26.
  • the downward force of the beam 50** against the bottom of the rail, and the counteracting upward force of the wings 28** against the bottom of the track 26 provide additional friction and a higher degree of grip of the end cap 22** on the rail 16 than in the previous end cap 22'.
  • the amount of movement of the outriggers 30** is very small, and the degree of interference fit of the wings 28** between the tracks 26 and the rail 16 is also very small.
  • the spring force provided by the outriggers 30** and the spring force caused by the deformation of the end cap 22** as it is installed on the rail (flattening from the arcuate shape shown in Figure 20 to a flat shape shown in Figure 22 ) allow for numerous removals and reinstallations of the end cap 22** onto the rail 16 without the end cap 22** losing its gripping force on the rail 16.
  • the end cap 22** continues to hold well on the end of the rail 16 even after many removals and reinstallations.
  • Figures 28-30 show a further modification to the end cap 22**.
  • This modification involves cutting out notches 58** from the rear edge of each of the outriggers 30**.
  • These notches 58** allow greater flexing of the rear portion of the wings 28** relative to the beam 50**, which reduces the wedging between the wings 28** and the rail 16.
  • the amount of holding power can be adjusted by adjusting the length of the notches 58** from the rear edge of the outriggers 30**.
  • the end cap 22** may be manufactured with the notches 58** already present instead of cutting out these notches 58** off of the end cap 22** of Figures 26 and 27 . It should also be noted that the length of these notches 58** may be varied from zero (essentially no notches present, as shown in Figures 24-27 ) which maximizes the degree of holding power for this embodiment of the end cap 22**, to whatever length is needed to obtain the desired degree of holding power; the longer the length of the notches 58**, the lower the degree of holding power. Furthermore, there may be a notch 58** in only one of the outriggers 30.
  • the embodiment of Figure 28 has identical notches that are mirror images of each other, the notches 58** may have different lengths or have different profiles in order to obtain just the desired amount of holding power. Finally, the notches 58** may be replaced by, or used in conjunction with, changes in thickness of the outriggers 30** adjacent to the wings 28**, providing the wings 28** with more flexibility relative to the beam 50** adjacent to the rear edge of the wings 28** and ultimately reducing the holding power of the end cap 22**.
