DETAILED DESCRIPTION

(16) The following description sets forth the invention and method of use in several embodiments. Those having ordinary skill in the art may be able to make alterations and modifications to what is described herein without departing from its spirit and scope. While this invention is susceptible to different embodiments in different forms, there is shown in the drawings and will herein be described in detail a preferred embodiment of the invention with the understanding that the present disclosure is to be considered as an exemplification of the principles of the invention and is not intended to limit the broad aspect of the invention to the embodiment illustrated. All features, elements, components, functions, and steps described with respect to any embodiment provided herein are intended to be freely combinable and substitutable with those from any other embodiment unless otherwise stated. Therefore, it should be understood that what is illustrated is set forth only for the purposes of example and should not be taken as a limitation on the scope of the present invention.

(17) The present invention provides a door handle attachment that adheres to a sliding door. The invention provides a raised handle ridge, which a user may grip or to which a user may simply apply force for opening or closing a sliding door. It should be noted that a door is a non-limiting example and a person having ordinary skill in the art would understand that the present invention has uses on other fixtures.

(18) Most contemporary North American sliding screen door designs do not include a raised ridge or other raised handle. Instead, most such screen door designs include a small recess in the door frame, e.g., rectangular in shape and roughly waist-high, which a user may reach in with the tips of her fingers to obtain a grip on the door frame for opening or closing. For door designs that include a lock or latch, the button or lever included for such a mechanism is usually presented inside this recessed grip.

(19) Many users find the recessed grip cumbersome, uncomfortable, inefficient, or ineffective. Users who find the recessed grip unsatisfactory often choose to slide the door by grabbing the whole frame between the thumb and fingers. Such use is not intended by the manufacturer and is likely to increase wear-and-tear on the door, and for wire mesh screen doors is likely to cause the mesh screen to separate from the door frame. Some users may even choose to cease using the door.

(20) Additionally, users of below average or above average height, particularly small children, may not be able to reach the recessed grip. Furthermore, persons in wheelchairs, persons having had amputations, persons having arthritis, persons having Parkinson's disease, and persons with other ailments or disabilities may find the recessed grip especially difficult to operate.

(21) The present invention solves the above-stated problems by providing a door handle attachment with a raised ridge. A user may attach one or more door handle attachments to any preferred location on the sliding door. The raised handle ridge allows users to easily and conveniently apply force to both open and close a sliding door. The fact that the door attachment can easily be applied at any location on the sliding door allows users to offer a grip to children or very tall persons.

(22) Furthermore, the raised ridge may by either gripped between the thumb and fingers or may simply be used as a surface against which to apply force to open or close the door. Accordingly, the raised ridge provides a convenient means to open or close a sliding door without requiring great strength or dexterity of the hands. For example, with the present invention a user could open or close a sliding door with a prosthetic hand or even a cane.

(23) Turning to the drawings, FIG. 1a illustrates a door handle attachment 100a. The door handle attachment 100 is substantially rectangular in shape and includes a lateral support member comprising lateral support wings 130a, 130b, a handle ridge 120 and an adhesive backside 110. Handle ridge 120 is disposed longitudinally down door handle attachment 100 on the front side. In some embodiments, handle ridge 120 extends from the front side at a substantially 90-degree angle relative to the lateral support member 130 (including lateral support wings 130a, 130b). In some embodiments, such as the one depicted in FIG. 1a, the handle ridge 120 is positioned approximately centered along the lateral support member 130 such that lateral support wings 130a, 130b have the same width, yielding a substantially symmetrical configuration of door handle attachment 100. In alternative embodiments, such as the one depicted in FIG. 1b, the handle ridge 120 is positioned off-center along the lateral support member 130 such that lateral support wings 130a, 130b have different widths, yielding an asymmetrical door handle attachment 100b. In still another embodiment, the handle ridge 120 may be positioned at the edge of the door handle attachment 100 such that lateral support member 130 comprises only a single lateral support wing 130a (i.e., lateral support wing 130b is absent), as shown for example in FIG. 3c).

(24) In some embodiments, the handle ridge 120 may be the same or substantially similar length as lateral support member 130. In other embodiments, the handle ridge 120 may extend less than the whole length of the lateral support member 130. In some embodiments, the handle ridge 120 is substantially straight, while in other embodiments, the handle ridge 120 is crimped or provided with groves substantially conforming to a user's thumb and fingers. In one preferred embodiment, the door handle attachment 100a is a single piece of crimped metal, and the handle ridge 120 is formed from the crimped portion of the material.

(25) The back side of the door handle attachment 100 (i.e., the back side of lateral support member 130 including lateral support wings 130 a,b) comprises an adhesive 110. The adhesive backside 110 is a generally flat surface that may be coated with a chemical or mechanical adhesive suitable for mounting the door handle attachment onto a fixture such as a door frame. Non-limiting examples of chemical adhesives suitable for coating the adhesive backside 110 include cyanoacrylate, epoxy, polyurethane, rubber cement, pressure-sensitive glue, fabric glues, hot glue, spray glue, wood glue, and wax.

(26) Door handle attachment 100 may be made from any suitable metallic or non-metallic material or combination of materials. For example, in a preferred embodiment, the structure of the door handle attachment 100 is made from galvanized aluminum. Other non-limiting examples of suitable metallic materials include ungalvanized aluminum, iron, steel, brass, nickel, Monel metal, copper, bronze, tin, or lead. Some non-limiting examples of non-metallic materials include rubber, plastic, urethane, wood, carbon fiber, or composite. In some embodiments, the handle ridge 120 and lateral support member are made from the same material. In other embodiments, the handle ridge 120 is made from one selected material, and the lateral support member 130 are made from a different material. The door handle attachment 100 may be uncoated or may be optionally coated in any desired color of paint, primer, sealant, plating, or protectant, such as, e.g., by electrostatic coating or electroplating.

(27) FIG. 2a provides a general illustration of the dimensions of door handle attachment 100a. The door handle attachment 100a is generally elongated. In a preferred embodiment, the lateral support wings 130a, 130b are approximately 0.25 to 4 inches wide and approximately 6 to 36 inches long, and the handle ridge 120 is raised a suitable height from the surface of the lateral support members 130a, 130b. As illustrated in FIG. 2b, an asymmetric door handle attachment 100b having lateral support members 130a, 130b of non-equal widths may also be provided.

(28) Embodiments of the door handle attachment 100 may be produced by crimping a single piece of workable material, such as galvanized aluminum, folding the single piece to create handle ridge 120 such that lateral support wings 130a, 130b are discontinuous. In another aspect, two or more pieces are joined, e.g., by welding. In still another aspect, a single piece is made from injection molding, casting, or 3D printing.

(29) FIGS. 3a, 3b, and 3c illustrate various cross sections of crimped-style door handle attachments. The illustrated embodiments are generally made from a single piece of crimped material, forming the lateral support wings 130a, 130b and handle ridge 120. The handle ridge 120 forms the cross-sectional shape of an inverted V (i.e., Greek capital letter A). FIG. 3a depicts a symmetrical embodiment with the handle ridge 120 approximately centered on the door handle assembly 100 such that lateral support wings 130a, 130b have an approximately equal width. FIG. 3b depicts an asymmetric embodiment with the handle ridge 120 off-set from the center/midline of door handle assembly 100 such that lateral support wings 130a, 130b have different widths. FIG. 3c depicts a cross section of a crimped-style door handle attachment wherein handle ridge 120 extends from the longitudinal edge of a lateral support member 130 such that door handle assembly 100c has only a single lateral support wing 130a (i.e., lateral support wing 130b is absent). The depicted adhesive backside 110 is generally coated with a chemical adhesive, but alternatively may be disposed with physical fixative or adhesive elements such as loop-and-pile fasteners. Note that the cross section is not presented to scale and is intended for illustrative purposes.

(30) FIGS. 3d, 3e, and 3f illustrate various cross sections of T-shape/L-shape style door handle attachments in which the lateral support wings 130a,b are continuous/contiguous. The illustrated embodiments are generally made from a single piece of molded, cast, or 3D printed material. FIG. 3d depicts a symmetrical embodiment of a T-shape style door handle attachment with the handle ridge 120 approximately centered on lateral support member 130 such that lateral support wings 130a, 130b have an equal width. FIG. 3e depicts an asymmetric embodiment of a T-shape style door handle attachment with the handle ridge 120 off-set from the center of lateral support member 130 such that lateral support wings 130a, 130b have an unequal width. FIG. 3f depicts an L-shape style door handle attachment wherein the handle ridge extends from the longitudinal edge of a lateral support member 130. The depicted adhesive backside 110 is generally coated with a chemical adhesive, but alternatively may be disposed with physical fixative or adhesive elements such as loop-and-pile fasteners. Note that the cross section is not presented to scale and is intended for illustrative purposes.

(31) FIG. 4a illustrates one example of a standard mesh-screen sliding door 400 having a substantially rigid rectangular frame 410, the frame having on one vertical member a recessed handgrip 420, and the frame suspending a taut mesh screen 430. FIG. 4b illustrates such a sliding door 400 having the door handle attachment 100a adhered to the frame 410 above the recessed handgrip 520. FIG. 4c illustrates the same, except having the door handle attachment 100 adhered below the recessed handgrip 420. FIG. 4d illustrates the same, except having two door handle attachments 100, one adhered to the frame 510 above the recessed handgrip 420 and one adhered to the frame below the recessed handgrip 420. Having two door handle attachments 100 adhered to the door frame 410 may be advantageous in a household having small children, for example. It is understood that one or more of the door handle attachments 100 may be affixed to the interior-facing surface of the sliding door, the exterior-facing surface of the sliding door, or both, depending upon the user's preference.
