The present invention relates to an attachment that is variably colored textured or marked that contains or holds the opposing pull leads used for a device operation to indicate direction, and, more particularly, to indicate pull direction. This device may be attached to a wall or a floor or window casing or any similar object.
Window coverings typically use a pull lead, such as a pull cord, a link chain, a bead chain or a ball chain, to rotate a series of vertical or horizontal slats, or open or close the window covering. By pulling on one side of the lead, the slats rotate in one direction, e.g., to the right, or the blinds or curtains open. By pulling on the other side of the lead, the slats rotate in the opposite direction, e.g., to the left, or the blinds or curtains close. Some window coverings have pull leads that are anchored to the floor, to the wall, or to the window casing so that the pull lead may be pulled up or down to operate the window covering.
However, the user has no indication as to which side of the lead will perform the desired operation. The user must randomly choose one side to determine the operation performed by pulling on that side, which may not be the desired operation. The resulting undesired movement of the window covering results in user frustration and wasted time.
In addition to frustrating the operator, pulling the incorrect lead introduces unnecessary wear and tear on the mechanisms of the window covering. For example, if the window covering is opened fully, a pull on the wrong lead stresses the lead and the mechanism because the window covering does not move in response to the downward pulling force.
Further, some users with limited sight or users in darkened rooms may have difficulty observing the pull lead, and some users may have difficulty grasping the pull lead. Additionally, there are other devices, such as machines and lighting, that are operated with a pull lead, which may be frustrating for the user to operate due to lack of a directional indicator.
An embodiment of the present invention provides a holder indicating a pulling direction of a pull lead for a desired operation of a device. The holder separates and indicates the opposing pull leads. The holder includes a directional indicator on or incorporated within the surface of the part that holds a selected pull lead consisting of a variation in color, a variation in texture, and combinations thereof, so that a pulling direction is indicated for a desired pull lead operation of such device. The first part or one part of the holder may be a different color than the second part. The directional indicator on the holder may include indentations. The directional indicator may include a non-slip material. The directional indicator may include a color gradient. The directional indicator may include an object. The directional indicator may include a decorative pattern. The directional indicator may include an arrow. The directional indicator may be etched into the surface of the holder. The directional indicator may include an application of a decal. The directional indicator may include a raised portion. The directional indicator may glow in the dark. The directional indicator may be illuminated.
The directional indicator may include a sleeve about the pull lead. The sleeve may be clear or colored to indicate direction. The sleeve may be about at least: the first bead, the second bead, and the shank. The sleeve may include a variation in color. The sleeve may include a variation in texture.
A first section of the holder holding the pull lead may include a first directional indicator to indicate that pulling the first section of the pull lead will result in a first operation of the device, and a second section of the holder may include a second directional indicator to indicate that pulling the second section of the pull lead in that section will result in a second operation of the device.
Another embodiment of the present invention provides a holder indicating a pulling direction of the pull lead for a desired operation of a device, the directional indicator consisting of a variation in color, a variation in texture, and combinations thereof, so that a pulling direction is indicated for a desired operation of such device.
A first section of the holder may include a first directional indicator to indicate that pulling the first section of the pull lead will result in a first operation of the device, and a second section of the holder may include a second directional indicator to indicate that pulling the second section of the pull lead will result in a second operation of the device.
The first part and the second part of the directional holder indicator may include a receptacle adapted to receive the opposing sides of the pull lead.
Another embodiment of the present invention provides a method for positioning a directional indicator on opposing sides of the device, wherein the holder includes a directional indicator along a length of the holder, the method including: attaching the pull cord to the device so that the directional indicator on a first side of the holder indicates a first direction and the directional indicator on a second side of the holder indicates a second direction opposite the first direction, wherein pulling the first side of the pull cord contained in the holder performs a first
The detailed description set forth below in connection with the drawings is intended as a description of embodiments of a color and/or texture variability for use with a pull lead holder in accordance with the present invention and is not intended to represent the only forms in which the invention may be constructed or utilized. It is to be understood that the same or equivalent functions and structures may be accomplished by different embodiments that are also intended to be encompassed within the spirit and scope of the invention. As denoted elsewhere herein, like element numbers indicate like elements or features.
As shown in
A visually and texturally distinctive pattern may also be formed by applying sequins or rhinestones to the outer surface of the holder. Other distinctive elements could also be used. The distinctive elements may also be applied in a wide variety of patterns and/or symbols to designate a direction on the holder for operation of the pull lead.
The texture variation or texture gradation may be formed when the holder is manufactured or applied later. The design may be plastic or metal.
If applied, it may be any other suitable material, such as composites, recycled materials, silicone, or latex rubber. In other embodiments of the present invention, the decoration texture or coloration may be other shapes, including, but not limited to, an arrow, an elliptical or round shape, or a multi-faceted shape.
The color pattern, or any other directional pattern, on the holder may be applied to the entire length of the holder.
According to another embodiment of the present invention, the opening of the holder that grasps the lead may have varying diameters so that it does not tightly hold the lead. In another example, the holder may be formed of a clear material, such as plastic. The clear material may also incorporate colored or decorative elements such as a colored dye or sparkles. These decorative elements may be arranged to indicate a direction that the pull chain should be pulled.
In another embodiment of the present invention, there is a gradation of the colors, or a gradation in a glow-in-the-dark material, along the holder from lighter to darker. This would signal to a user that they should pull the lead held in the darker section of the holder to close and the lighter section of the holder to open.
The indictor holder may be fixed to a stationary object, such as the floor or the window casing.
