Description

Valance connector

Technical Field

The utility model belongs to the valance connector field.

Background

The valance arrangement includes fabric, a sliding rail, a set of pulleys and connectors that enable the system to move around the sliding rail. As with the prior art, the sliding device has extended product life and is convenient to adjust, compared to older designs that do not use sliding guides.

One example of such a sliding valance arrangement is U.S. patent US7,698,781B2, published by Cai, 20.2010, which details an arrangement that utilizes a dedicated pulley that provides cheaper labor costs and more joint safety in the wheel structure.

Another example is a window covering system utilizing a rolling ball discussed in U.S. patent 6189182B1 issued by inventor Kuen-Tin Ko on 2/20/2001. In this example, inventor Ko discusses a guide block for pulling a window covering comprised of a pull plate, a set of wheel mounts, and a plurality of rolling balls confined therein. The rolling action provides a smoother mechanism and also reduces friction and collisions within the window covering system. Unfortunately, many existing systems are subject to plugging and winding problems.

Detailed Description

As shown in fig. 1-4, the present invention shown in the drawings is a valance connector. The valance connector generally has an upper carriage 30, the upper carriage 30 including a roller frame 37 to which a wheel is mounted. The wheels 39 rotate relative to the roller frame 37 on axles 38 mounted to the roller frame 37. The axle 38 may not be visible from the outside, and the axle 38 may be covered by a portion of the roller 39. The roller is formed from two separate similar pieces of plastic that are mounted in mirror image relation to each other.

The roller frame 37 is rigidly connected to the connector body 20 at the swivel socket 25. The connector body 20 includes a rotary socket 25 and a lower connector body 22. Swivel sockets 25 hold connector body swivel head 24 in a pivoted swivel configuration. Connector body swivel 24 may be integrally formed with connector body rotation shaft 23, connector body rotation shaft 23 extending downwardly from connector body swivel 24. The diameter of connector body swivel 24 is greater than the diameter of connector body axis of rotation 23. The connector body rotating shaft 23 is preferably cylindrical and supports the lower connector body 22. The lower connector body 22 includes a valance connector receptacle 21, the valance connector receptacle 21 having a valance connector receptacle opening for receiving a portion of the valance 46. The valance connector receptacle 21 can receive valance snaps 47, the valance snaps 47 snapping into the valance connector receptacle 21. The valance snap 47 can be formed as a button, such as a metal button with an annular protrusion. Drape connector receptacle 21 preferably has an opening through connector receptacle frame 29.

In use, valance 46 is supported by valance snaps 47. Valance snaps 47 are supported by valance connector receptacles 21. The valance connector socket 21 is supported by a connector socket frame 29. The connector jack frame 29 is supported by the lower connector body 2 and by the lower connector body 22. The lower connector body 22 is supported by the connector body rotation shaft 23. Connector body rotation shaft 23 is supported by connector body swivel 24. Connector body rotator head 24 is supported by rotary socket 25. The rotary sockets 25 are supported by the roller frame 37. The roller frame 37 is supported by an axle 38. The axle is supported by wheels. The wheels are supported by extrusions 50. Extrusion 50 is in turn mounted to a ceiling or wall.

Rotator head 24 is disc-shaped and fits into rotator socket 25. Connector body rotator head 24 is larger than rotation socket recess 26 so that rotation socket recess 26 has an upper surface that rests on the lower surface of the rotator head. The rotating connector body head 24 has a vertically oriented rotating head sidewall 27. The lower connector body 22 has a connector body face 28 formed in a flat planar shape. A connector receptacle frame 29 extends downwardly from the connector body face 28, and the connector body face 28 has a flat surface that is parallel to the valance connector receptacle 21 and the valance connector receptacle opening.

The wheel is preferably formed with a wheel plane 36 and a wheel inclined wall 35. The wheel inclined wall 35 extends from the wheel plane 36 and terminates at a roller radiused ramp 43. The wheel has an inboard roller bearing 42 which rides on the extrusion. The extrusion is preferably an aluminum extrusion. The upper carriage 30 also has a carriage disc 31 and carriage bars 32 extending upwardly from the carriage disc 31. The carriage bar 32 receives a carriage wire 33. The carriage bar 32 may be formed around the carriage wire 33 by injection molding around the carriage wire 33. The carriage bar 32 may be made of plastic and the carriage wire 33 may be made of a rope material. The carriage bar 32 preferably has a flat top upper surface referred to as a retainer face 34.

The wheel performs a rolling motion within the extrusion. Thus, the wheels are rollers. The wheel has a roller ridge 44, the roller ridge 44 extending away from the roller frame 37 to form a generally circular roller recess, with the roller recessed into the roller recess. The roller ridge 44 defines a roller notch 45 such that the inner surface of the wheel is not as far from the roller ridge 44. The wheel has a wheel inner vertical surface 48 and a wheel outer vertical surface 49. The wheel is formed as a pair of rollers, a front roller 55 and a rear roller 56, each having a wheel inner vertical surface 48 and a wheel outer vertical surface 49. Each roller has a roller recess 45 and a roller seal 41. The roller seal does not necessarily contact and is not a resilient washer, but rather a very small gap between the roller ridge 44 and the wheel interior vertical surface 48. The roller ridge 44 has a 90 angle directed towards the roller recess 45. The roller ridge 44 acts as a guard to prevent the carriage wire 33 from wrapping between the wheel interior vertical surface 48 and the roller frame 37. The roller ridge 44 may be nearly flush with the roller frame 37 without too large a height difference. The roller indentation may be a very slight indentation, barely perceptible.

The aluminum extrusion 50 preferably has an extrusion top wall 51 that can be screwed to a ceiling, and a pair of extrusion side walls 52, each extrusion side wall 52 having an extrusion guide wall 53. The crush rail wall 53 is a rail on which the rollers roll on the inner roller bearings 42. The extrusion forms an extrusion hollow 54 so that the inner upper carriage 30 travels in a translational motion. The trolley line 33 is connected between successive trolley bars 32 such that the trolley line 33 maintains a set distance between the upper carriage 30 and the successive upper carriage 58. The roller frame has a roller frame plane and the wheel inner vertical surface 48 is mounted very close to the roller frame plane 57 such that the gap between the wheel inner vertical surface 48 and the roller frame plane 57 is less than the diameter of the carriage line 33.

The key part of the invention is that the guide corners 59 of the extruded guide wall 53 receive a pair of rollers and the rollers travel along the guide corners 59, because the inclined wall 35 is inclined towards the axle 38, said inclined wall 35 thus forming a semi-conical profile of the rollers. The angled wall 35 engaging the guide rail corner 59 allows the carriage wire 33 (if looped) to slide between the angled wall 35 and the guide rail corner 59 so that it does not wrap around the roller.
