Floor squeegee

Abstract

There is disclosed a floor squeegee for spreading resin on floors or removing liquid spills or debris from floors and other flat surfaces. The squeegee includes a frame section, a handle connected to the frame section such that the frame section is generally perpendicular to handle, the frame section including a preset number of internally threaded locator bosses. A flexible squeegee blade section includes a preset number of boss holes extending therethrough to receive the preset number of internally threaded locator bosses. The flexible squeegee blade section has a first section and a second section being integrally formed with the first elongate section and being inclined at an angle with respect to the first section in a range from about 0 to about 90. The squeegee includes a clamp section having a preset number of boss holes extending therethrough to receive the preset number of internally threaded locator bosses, and a preset number of threaded nuts with the preset number of threaded nuts being threaded to be threadably received in the internally threaded locator bosses. When assembled the second blade section contacts a floor or other surface when in operation.

DETAILED DESCRIPTION

(6) Various embodiments and aspects of the disclosure will be described with reference to details discussed below. The following description and drawings are illustrative of the disclosure and are not to be construed as limiting the disclosure. Numerous specific details are described to provide a thorough understanding of various embodiments of the present disclosure. However, in certain instances, well-known or conventional details are not described in order to provide a concise discussion of embodiments of the present disclosure.

(7) As used herein, the terms, comprises and comprising are to be construed as being inclusive and open ended, and not exclusive. Specifically, when used in the specification and claims, the terms, comprises and comprising and variations thereof mean the specified features, steps or components are included. These terms are not to be interpreted to exclude the presence of other features, steps or components.

(8) As used herein, the term exemplary means serving as an example, instance, or illustration, and should not be construed as preferred or advantageous over other configurations disclosed herein.

(9) As used herein, the terms about and approximately, when used in conjunction with ranges of dimensions of particles, compositions of mixtures or other physical properties or characteristics, are meant to cover slight variations that may exist in the upper and lower limits of the ranges of dimensions so as to not exclude embodiments where on average most of the dimensions are satisfied but where statistically dimensions may exist outside this region. It is not the intention to exclude embodiments such as these from the present disclosure.

(10) FIG. 1 is a perspective view of the present squeegee device shown generally at 30 located above a floor surface 6 which is shown disassembled and which includes an elongate handle 2 having a threaded end portion 4. Elongate angle 2 may be a wooden, metal or plastic handle. Squeegee 30 includes an elongate frame 8 which includes a threaded receptacle 5 to receive therein threaded end portion 4 of handle 2. Elongate frame 8 includes at least one internally threaded locator boss 22, with five (5) internally threaded locator bosses 22 being shown in FIG. 1, which are spaced along the length of elongate frame 8 and project outwardly from the frame 8. An elongate, flexible rubber squeegee blade 10 having the same approximate length as elongate frame 8 includes at least one hole 20, with five (5) holes 20 shown in FIG. 1 having a diameter large enough to receive the locator bosses 22 when squeegee blade 10 is assembled with frame 8. Frame 8 and clamp 12 may be made from polypropylene or a variation of other plastic materials, which in turn makes it difficult for any cured floor coatings to bond to the frame 8 or clamp 12. In addition, all edges and corners on the frame 8 and clamp 12 are radiused or rounded thereby making it easier for the removal of cured coatings or debris. Rubber squeegee 10 is produced with two sections 10a and 10b at an angle of about 45. However it will be appreciated that the angle between sections 10a and 10b may vary in a range from about 0 to about 90.

(11) Rubber squeegee blade 10 may be made from different rubbers including EPDM, neoprene, silicone or urethanes or any combination thereof. The squeegee blade 10 may also be comprised of different durometers or a combination of different durometers in the same squeegee blade 10.

(12) Squeegee 30 includes a clamp member 12 which includes at least one locator hole 16, with five (5) locator holes 16 shown in FIG. 1 which are designed to align with holes 20 in rubber squeegee 10 and locator bosses 22 on frame 8 when the squeegee 30 is assembled. At least one thumb screw 14, with five thumb screws 14 being shown in FIG. 1, are spaced along clamp section 12 and when assembled the thumb screws 14 are passed through holes 16 in clamp section 12 and through holes 20 in the rubber squeegee 10 and then threaded into threaded boss holes 22 when the squeegee device 30 is assembled.

(13) FIG. 2 is an elevation view of the squeegee looking from the front of the squeegee, and FIG. 3 is a sectional view of the squeegee of FIG. 2 taken along the line A-A. FIG. 4 is a blow-up of the circled section A in FIG. 3 and as can be seen, clamp section 12 includes a curved peripheral edge 18 which mates with the curved surface 24 on the peripheral edge on frame 8. The threaded ends of nuts 14 are totally enclosed within the threaded bosses 22.

(14) FIGS. 1, 3 and 4 show a raised lip 33 peripherally disposed around locator hole 16 which is included to prevent material from potentially bonding fastener 14 to clamp 12. FIG. 4 shows a non-threaded end of the threaded fastener or nut 14, where a flange 35 of the non-threaded end of the threaded nut 14 contacts the raised lip 33 when fully threaded into the boss holes 22 and has an outer diameter which is greater than an outer diameter of the raised lip 33. The greater outer diameter of the flange 35 compared to the threaded nut 14 is advantageous as it prevents seepage of the liquid being spread by the squeegee into the internally threaded locator boss 22. FIGS. 1, 3 and 4 show raised areas 43 close to the perimeters of both the elongate frame 8 and the elongate clamp 12 which assist in holding the squeegee blade 10 in place and help to prevent seepage of material between the blade 10 and the clamp 12 or the frame 8. The internally threaded locator bosses 22 may include overmolded threaded inserts 34 which may be made of brass, to give one non-limiting example. The above noted features are very advantageous in that when the squeegee 30 is fully assembled and used in the spreading of floor coatings, the coating material will not interfere or come in contact with the threads of the fasteners 14 which provides for easier changing of the squeegee blades 10.

(15) The present squeegee may be produced with different lengths of the frame 8, flexible squeegee section 10 and clamp section 12, depending on the application for which the squeegee is intended. For example a hand held version may be produced which may be a few inches long for use in restricted spaces, or longer versions of a couple of feet long may be used for applications where large surface areas are being coated.

(16) The squeegee disclosed herein is very advantageous over conventional squeegees for the following reasons. Since the threaded ends of the fastening nuts are sealed inside the frame 8, the resinous materials be spread by the squeegee will not hinder the fastening nuts 14 as they are internal threads and blind holes with no exposure to the resinous materials. In addition, in the case of an angle greater that 0 between the squeegee sections 10a and 10b, the flexible squeegee blade has been angled as opposes to the squeegee frame having a built in angle which keeps the fasteners 14 further away and at an upward angle from the resinous materials. Further, the present squeegee 30 has internally threaded bosses 22 and corresponding holes 22 in the flexible squeegee and corresponding holes in flexible squeegee section 10 so that all the components are forced into perfect when the squeegee is assembled.

(17) The specific embodiments described above have been shown by way of example, and it should be understood that these embodiments may be susceptible to various modifications and alternative forms. It should be further understood that the claims are not intended to be limited to the particular forms disclosed, but rather to cover all modifications, equivalents, and alternatives falling within the spirit and scope of this disclosure.
