This application claims the benefit of U.S. Provisional Patent Application No. 60/515,308, filed on Oct. 28, 2003.
This invention relates generally to a squeegee handle assembly. More particularly, this invention relates to a squeegee handle assembly for holding a squeegee applicator having opposing blade members and a central portion having spaced parallel stabilizing ribs.
Squeegee applicators are known and have been used in the graphic, sign, tape, film, adhesive, silk screen and pressure sensitive adhesive industries for many years. These applicator tools may be used as applicators, squeegees and spreader tools and are provided in various configurations, i.e., square or round corners, in various sizes, i.e., 4, 6 and 12 inches in length, and constructed of various materials, i.e., polyethylene, nylon, teflon, PVC, rubber or poly blends. Importantly, these squeegee and applicator tools have specific durability, glide, memory and flexibility requirements and standards.
Although squeegee application tools are provided in the marketplace in many sizes, structures and configurations, most are formed to have opposing tapered blade structures separated by a pair of centrally disposed parallel stabilizing ribs which are protrusions or ridges formed on the central portion of the squeegee body and which are grasped by the user's hand during use.
Squeegee application tools are typically utilized by direct hand manipulation which allows the user to feel and control the movement and deformation of the pliable squeegee bodies via directed forces. The use of various tool handles have been proposed and used in the marketplace, however, the utilization of these applicator tool handles effect the user's feel, control and performance of the squeegee applicators. For example, in U.S. Pat. No. 5,865,945 to McConaughy a pressure sensitive film applicator tool handle is disclosed having a generally elliptical handle body having a slot and an internal gripping arrangement that grips the central portion of the applicator tool between the spaced protrusions. The gripping arrangement of this handle body limits the flexibility of the squeegee applicator and particularly the control of the blade of the applicator being utilized. U.S. Pat. No. 6,453,970 to Stone et al. discloses an applicator tool for applying decals to surfaces of automobiles wherein a tubular member is provided having a slot which engages the applicator tool in the valley between the spaced apart protrusions to provide angular movement of the applicator blade. Although these prior art tool handles may allow specific uses of the squeegee applicator, the handle structures hinder and limit the user's feel, performance and use of the squeegee for many other applications. Particularly, the torsional movement of the squeegee applicator blades is impaired by the utilization of these prior art handle members. Therefore, a need exists in the marketplace to provide a squeegee handle which allows a user to utilize a squeegee applicator blade without impeding or limiting the user's feel and function of the squeegee applicator body itself.
The squeegee handle assembly of the present invention comprises a tubular structure with squeegee holding means which minimize the impairment of the feel, function and performance of the squeegee applicator body. The handle assembly is comprised of a tubular body having a formed elongated opening and a cooperating blade stabilizing structure within the tubular body. The tubular structure has an externally lipped opening to engage the squeegee applicator over the first rib or protrusion of the squeegee body. The externally lipped opening of the tubular handle structure provides outwardly protruding lips which are configured to extend between the parallel ribs of the squeegee applicator and which permit the squeegee blade to flex and roll or pivot during use. Preferably the opposing lips diverge outwardly to permit the tapered blades of the squeegee applicator to flex and roll or pivot during use.
The tubular handle structure has a predetermined diameter to secure one blade of the squeegee applicator between the first protrusion and the interior wall of the tubular handle structure. The tubular structure also permits the interior blade to flex and roll or pivot during use. The tubular handle structure further has a stabilizing structure, such as stabilizing fins, disposed along its interior periphery opposite the lipped opening to receive the tip of the interior squeegee blade. The stabilizing fins are preferably in a divergent relationship to receive the tapered blade end of the squeegee and to permit the squeegee body to flex during use. A pair of end caps are further provided to maintain the squeegee body therebetween and which maintains the blade disposed on the interior of the handle in a clean condition and/or to maintain a used blade away from contact with a user's hand.
It is an advantage of the present invention to provide a functional handle assembly for use with a squeegee applicator body. The handle assembly provides two spacially aligned holding structures for specified portions of a squeegee applicator body. Specifically, a divergent fin structure is provided on the interior wall of the tubular handle body to engage the tip of the blade held within the handle body. In cooperation, a diverging external lip structure is provided to engage the stabilizing rib of the applicator body. These cooperating holding structures permit the squeegee applicator to flex and twist during use to thereby maximize the function of the squeegee when used with a handle assembly.
In use, one of the tapered blades of the squeegee is laterally slid into the handle structure whereby the squeegee body is held or trapped between the divergent lipped opening and the divergent stabilizing fins. The opposing external lips of the handle structure are curved outwardly to allow easy insertion of the squeegee into the handle and to permit the squeegee body to flex and roll or pivot at the blade sections and the midsection during use. The end caps maintain the squeegee body within the handle structure and keep the trapped blade in a clean condition disposed in the interior of the tubular handle. Subsequently, the used blade may be housed within the handle structure to thereby prevent undesirable substances to contact the user's hand.
These and other benefits of this invention will become apparent from the following description by reference to the drawings.
Referring to the drawings, the present invention relates to a squeegee handle assembly 10. The squeegee handle assembly is constructed and arranged to engage and hold a squeegee applicator 25, which is shown in
As the edge of the blade becomes worn, the user may switch use to the opposite blade. The force of the blade edge against the hand and/or a soiled blade may cause a user to desire utilizing a handle. However, it is important that the handle does not impair the function and performance of the squeegee applicator. For example, the flexing and torsional movement of the squeegee body 26 is important in the utilization of the applicator.
Referring to
The tubular handle body structure 11 has a predetermined inside diameter 17 to secure one blade of the squeegee 25 between the first rib 32 and the interior wall 13 of the tubular handle structure 11. The tubular handle structure 11 further has stabilizing member 18 shown comprised of stabilizing fins 19 and 20 disposed along its interior periphery opposite the opening 12 to receive the tip of the interior squeegee blade. The stabilizing fins 19 and 20 are shown extending from the interior wall 13 in a V-shaped or divergent configuration to thereby receive the tapered end of the squeegee blade. This arrangement permits the interior blade of the squeegee body to flex and roll within the handle body structure during use.
The tubular body 11 may be formed of a semi-rigid polymeric or plastic material via extrusion for example. The polymeric material may be polyethylene, PVC, ABS, poly blends, styrenes or like materials. The squeegee holding means are unitary with the body and formed during the extrusion process, for example.
A pair of end caps 21 and 22 are provided which maintain the squeegee body 26 therebetween and which maintain the blade disposed on the interior of the handle body 11 in a clean condition. As shown in
Referring to
As further shown, end caps 21 and 22 are shown positioned over the ends of the tubular body 11. Slots 23 and 24 in the end caps 21 and 23 are shown to receive the external lips 15 and 16 of the tubular body 11. The slots 23 and 24 have a width which permit the lips 15 and 16 to be in a spread apart configuration and holding the squeegee applicator 25. The end caps may be constructed of a semi-rigid or flexible polymeric or rubber material. The soft flexible material provides a handle assembly which is safe and worksite compatible. The end cap material composition may be smooth on the interior to provide a frictional hold with a smooth outer surface 14 of the tubular body 11, i.e., a smooth polymeric surface formed by injection molding or formed via extrusion. The exterior of the end cap may be a textured surface to enhance gripping.
During use, the operating blade will flex and twist depending upon the surface on which it is used. The torsional movement of the operating blade has an opposite effect on the blade captured in the handle assembly. The structure and composition of the externally lipped opening and stabilizing member of the handle assembly allow the captured blade to engage in the natural opposite movement to thereby compliment the function of the operating blade.
In use, one of the blades of the squeegee 25 is slid into the handle structure 10 between the divergent lips 15 and 16 of opening 12 and the divergent stabilizing fins 19 and 20. The opposing lips 15 and 16 of the handle structure 11 are curved outwardly to allow easy insertion of the squeegee 25 into the handle body 11 and to permit the squeegee 25 to flex and roll or pivot at the midsection 31 during use. The end caps 21 and 22 maintain the squeegee body 26 within the handle structure 11 and keep the trapped blade in a clean condition disposed in the interior of the tubular handle body 11. The handle assembly 10 provides a user with a comfortable ergonomic hand grip which permits the applicator tool to function as intended.
As discussed, squeegee applicators may be provided in any length, i.e., approximately 4, 6 and 12 inches (approximately 10.2, 15.2 and 30.5 cm, respectively) and the length of the tubular handle body is approximately the same length as that of the squeegee applicator with which it is used. The dimensions, other than the length, for the squeegee applicators as well as those of the tubular handle bodies are generally the same. For example, a squeegee applicator 25 having a length of approximately four inches (10.2 cm), an overall width of approximately 3.0 inches (7.6 cm), a blade width of approximately 1 inch (2.5 cm), stabilizing ribs with a diameter of approximately 0.31 inches (8 mm), a central portion having a width of approximately 0.31 inches (8 mm) and having a central portion thickness of approximately 0.13 inches (3 mm) and blades which taper from approximately 0.16 inches (4 mm) to approximately 0.03 inches (1 mm) may utilize a squeegee handle assembly 10 having dimensions as follows: a tubular body length of approximately 4 inches (10.2 cm), an inner diameter of approximately 1.25 inches (3.2 cm), a wall thickness of approximately 0.08 inches (2 mm), divergent lips each extending outward from the tubular body approximately 0.2 inches (5 mm), stabilizing fins each extending outward from the interior of the tubular body approximately 0.31 inches (8 mm). The stabilizing fins may be spaced apart approximately 0.06 inches (1.5 mm) at the base and approximately 0.125 inches (3 mm) at the top. The stabilizing fins extend into the tubular body approximately 25% of the body inner diameter. The end caps may have a diameter of approximately 1.31 inches (3.3 cm), a length of approximately 0.88 inches (2 cm) with a slot length of approximate 0.7 inches (1.8 cm) and width of approximately 0.38 inches (1 cm). The above dimensions are exemplary and other dimensions for the handle assemblies and associated squeegee applicators may be utilized according to the teachings and within the purview of the present invention.
As many changes are possible to the squeegee handle assembly embodiments of this invention, utilizing the teachings thereof, the description above and the accompanying drawings should be interpreted in the illustrative and not the limited sense.
