Description

FIELD OF THE INVENTION

The present invention relates to a utility tool. More particularly, in its intended preferred use, the present invention relates to a utility tool (e.g. a putty knife) having

assembly, for screwing purposes in drywall applications and the like, designed also for carrying out various other related multitask functions.

BACKGROUND OF THE INVENTION

Known in the art are various utility tools used for drywall applications and the like, such as putty knives, screwdrivers, etc.

For example, U.S. Pat. No. 2,092,586 granted on Sep. 7, 1937, to NAUMOVICH relates to a screw driver. There is described an article which is characterized by a flat metallic handle portion adapted to continue into a scraper blade, and a screw driver pivotally mounted on the rear end of said handle portion and adapted to assume a closed position against one side portion of said handle.

U.S. Pat. No. 6,530,098 B1 granted on Mar. 11, 2003, to GRINGER et al. relates to a multiple tool device. There is described a taping knife which includes a continuous shaft having a blade on a first end thereof, and a hammer on a second end thereof. A handle surrounds the shaft with the blade extending from one end thereof, and the hammer extending from the other end thereof. The handle preferably is constructed with a molded inner core and a soft molded rubber overlay. The hammer includes a hammering surface generally perpendicular to a central axis of the handle. The inner core is preferably constructed of a molded thermoplastic, and the overlay is preferably constructed of an injection molded rubber. The handle may include a bit storage slot for receiving and storing a screwdriver bit. The overlay may include a plurality of flexible fingers adjacent to the bit storage slot for securing a screwdriver bit in the slot. The hammer may include a sleeve for receiving a screwdriver bit with a working portion of the bit extending from the sleeve.

Also known to the Applicant are the following US patents, patent application and industrial design which describe various utility tools and the like, some of which contain integrated and retractable screwdriver attachments: U.S. Pat. Nos. 2,810,194; 2,839,110; 3,774,252; 5,063,627; 5,251,352; 5,720,063; 5,870,786; 5,927,164; 6,131,222; 6,272,708 B1; 6,530,098 B1; 6,662,521 B1; 6,769,147 B1; 6,996,868 B1; 2009/0313765 A1; and D380,661.

It is also known in the art that workers need to use different tools in order to carry out different tasks during drywall applications and the like, and the use of different tools is somewhat disadvantageous in that, namely, time is wasted when going from one tool to another, and that additional space is required for the provision of such various tools in a given tool box, tool belt, etc. Therefore, it would be useful to provide a tool, such as a putty knife for example, which would be devised to carry out several tasks which would normally be done by means of a plurality of different other corresponding tools.

Some of the above-listed documents described utility tools comprise integrated and retractable screw bit mechanisms, but these mechanisms are known to be not optimal in terms of design, ergonomics, multitasking, easy of use and other considerations (ex. torque transfer when screwing fasteners, etc.).

Hence, in light of the aforementioned, there is a need for a utility tool, which by virtue of its design and components, would be able to overcome some of the above-discussed prior art concerns.

According to a preferred embodiment of the present invention, and as better shown in FIGS. 13-22, the inner component 39 of the swiveling support component 33 preferably comprises a cam-shaped component 41, and the resilient component 37 of the biasing assembly 13 comprises top and bottom ends 43,45, the bottom end 45 being securely anchored to the handle assembly 11 and the top end 43 being tapered with respect to the bottom end 45 and being also resiliently displaceable within a given range, the top end 43 of the resilient component 37 pushing against the cam-shaped component 41 for automatically urging the screw bit assembly 7 towards the operating configuration when the swiveling support component 33 is located between the operating position and the transitional position, and for automatically urging also the screw bit assembly 7 towards the non-operating configuration when the swiveling support component 33 is located between the non-operating position and the transitional position.

Preferably also, swiveling support component 33 of the screw bit assembly 7 comprises an inner channel 47 for receiving the top end 43 of the resilient component 37, said inner channel 47 being positioned, shaped and sized within the swiveling support component 33 for allowing resilient displacements of the top end 43 of the resilient member 37 within the inner channel 47 and against the cam-shaped component 41 when the swiveling support component 33 is operated between its operating and non-operating positions.

As better shown in FIGS. 13-22, the inner channel 47 is defined between a pair of lateral surfaces 49 of the swiveling support component 33, and wherein the entry 51 to the inner channel 47 is provided on a bottom portion of the swiveling support component 33.

The swiveling support component 33 is preferably provided with a flat end 53 positioned, shaped and sized to carry out the function of a nailing cap 55 when the screw bit assembly 7 is in the non-operating configuration, and according to a preferred embodiment of the present invention, the flat end 53 is provided on the swiveling support component 33, within the same plane defined by the peripheral side edge.

As can also be better easily understood when referring to FIGS. 13-23, the swiveling support component 33 may also be provided with a finger receiving portion 57 for enabling a swiveling of the screw bit assembly 7 into the operating configuration via a pressing action by a corresponding finger of a user of the utility tool onto said finger receiving portion 57, the finger receiving portion 57 being preferably provided adjacent to the entry 51 of the inner channel 47 of the swiveling support component 33, as better shown in FIGS. 13-16.

Preferably also, the finger receiving portion 57 is provided with a series of corresponding transversal ribs 59 for facilitating an improved grip and corresponding activation of the finger receiving portion 57, and the flat end 53 (i.e. nail cap 55) is positioned adjacent to the finger receiving portion 57.

As can also be better easily understood when referring to FIGS. 13-14, the handle assembly 15 comprises an inner core 61 made of a substantially rigid material, while comprising corresponding overlaying portions 63 made of an elastomeric material, for improving manipulation and grip of the handle assembly 11 and of the corresponding utility tool 3, the swiveling support component 33 being pivotably mounted onto the inner core 61, about the rear portion 19 of the handle assembly 11.

Preferably also, swiveling support component 33 is pivotably mounted onto the handle assembly 11 by means of an eyelet 65, the eyelet 65 providing the utility tool with a corresponding bore 67 extending through the handle assembly, from the top gripping surface 23 to the bottom gripping surface 25 thereof, for enabling to hang the utility tool 3 onto a corresponding support structure, as better be easily understood when referring to FIGS. 1-4.

According to a preferred embodiment of the present invention, the bottom end 45 of the resilient component 37 is secured affixed onto the inner core 61 of the handle assembly 11 via appropriate fasteners 69 (ex. rivets, etc.) and abuts against a distal end 71 of the blade 5 inside the inner core 61 of the handle assembly 11. The distal end 71 of the blade 5 is preferably force-fitted into the inner core 61 of the handle assembly 11 via appropriate securing means (ex. fishbone 73, etc.), as can be easily understood when referring to FIGS. 12-14.

As also better shown in FIGS. 12-14, the swiveling support component 33 comprises a socket 75 being positioned, shaped and sized for selectively receiving a corresponding screw bit 77 being removably insertable into said socket 75. Preferably, the socket 75 is magnetized with respect to the screw bit 77, such as, for example, with a corresponding magnet component 79, so as to further retain the screw bit 77 within the socket 75. It is worth mentioning also that the handle assembly 11 of the utility tool 3 can be provided with a storing space 81 for storing and allowing an interchangeability of removable screw bits 77 with a corresponding socket 75 of the swiveling support component 33 of the screw bit assembly 7.

As better shown in FIG. 7, and according to a preferred embodiment of the present invention, the slanted angle θ is comprised between about 90 degrees and about 150 degrees with respect to the longitudinal axis 15 of the handle, and the swiveling support component 33 is positioned, shaped and sized so to provide a clearance, between a working surface 9 and the handle assembly 11, for the fingers of a user of the utility tool 3, when the screw bit 77 is substantially perpendicular with respect to the working surface 9, as can be easily understood when referring to FIGS. 23-24. According to a preferred embodiment of the present invention, the slanted angle θ that is securely and automatically maintained via the biasing assembly 13 is about 120 degrees. Indeed, the present utility tool 3 is preferably designed so that the screw bit assembly 7 can only be moved from the operating configuration to the non-operating configuration, and vice-versa, via a “manual override” of the swivel support component 33, either by manually pushing/pulling onto the projecting portion of the swivel support component 33 (or onto the screw bit component 31 thereof), or preferably, by using the finger receiving portion 57, so as to “snap” the screw bit assembly 7 back into a corresponding configuration, otherwise, the swivel support component 33 is preferably meant to always be kept securely maintained in a corresponding configuration (whether “operating” or “non-operating”) by means of the biasing force provided by the resilient member 37 of the biasing assembly 13.

It is worth mentioning also that according to another preferred embodiment of the present invention, the screw bit assembly 7 could be configured so as to be triggered via a corresponding activation button 83, the swiveling support component 33 being spring-loaded via another suitable biasing assembly 13, so that upon activation of the activation button 83, the swiveling support component 33 and corresponding screw bit component 31 are automatically elevated via the action of the spring load into the operating configuration, for a “quick-release”, as can be easily understood by a person skilled in the art.

According to a preferred embodiment of the present invention, and as can be easily understood when referring to FIGS. 9-11, an outer contour 85 of the swiveling support component 33 is complementary in shape with respect to a rim 87 of the recess 35 of the peripheral side edge 21, when the swiveling support component 33 and corresponding screw bit component 31 are nested within the recess 35, so that, among other advantages, an almost “seamless” handle assembly 11 is ergonomically provided when the utility tool 3 is used and when the swiveling support component 33 is the non-operating configuration. Indeed, it may be appreciated that when in such a configuration, in addition to being kept securely nested in the recess 35 by means of the cooperation between the resilient member 37 and the cam-shaped component 41, the swiveling support component 33 and corresponding screw bit component 31 do not interfere with the gripping surfaces 23,25 of the handle assembly 11.

According to a preferred embodiment of the present invention, and as better shown in FIGS. 1 and 2, the utility tool 3 is preferably a 11-in-1 tool, and comprises a first component 101 for setting drywall screws, a second component 102 for opening containers, a third component 103 for cleaning paint rollers, a fourth component 104 for opening paint cans, a fifth component 105 for spreading drywall compound, a sixth component 106 for scraping, a seventh component 107 for closing paint cans, an eighth component 108 for scraping concave surfaces, a ninth component 109 for scraping convex surfaces, a tenth component 110 for pulling nails, and an eleventh component 111 for cleaning out cracks.

As previously explained, the utility tool 3 includes an elongated handle 1 for manual handling of the utility tool 3, a blade 5 and a screw bit assembly 7 (hereinafter referred to also as a screw bit “mechanism”). The handle 1 extends substantially along a longitudinal axis 15, and has front and rear portions. The blade 5 has an anchoring portion anchored within the handle 1 and an operating portion extending out from the front portion of the handle 1. The screw bit mechanism 7 is rotatably mounted about the rear portion of the handle 1, has a screw bit 31, and is operable between a non-operating configuration where the screw bit 31 is nested within the handle 1, and an operating configuration where the screw bit 31 is drawn out of the handle 1 and securely maintained in a fixed configuration so as to be positioned at a slanted angle θ with respect to the longitudinal axis 15 of the handle 1, as can be easily understood when contrasting FIGS. 7 and 11, for example. Preferably, the slanted angle θ is comprised between about 90 degrees and about 180 degrees with respect to the longitudinal axis 15 of the handle 1, as also shown, and this provides substantial advantages, as will be described in greater detail hereinbelow.

As can also be easily understood by a person skilled in the art when referring to the accompanying drawings, the tool handle 1 is preferably securely affixed to a given blade 5, or other component, so as to form the resulting tool 3. The tool handle 1 preferably comprises an inner core 61 made of a substantially rigid material, such as a proper plastic or the like, while being provided with corresponding overlaying portions 63 preferably made of a more soft material, such as an elastomeric material, for improving manipulation and grip of the tool handle 1 and resulting tool 3. As previously explained, the tool 3 is preferably provided with a screw bit mechanism 7 being configured preferably so as to be rotatably activated between retracted and operating configurations, the screw bit mechanism 7 being provided with a least one finger receiving portion 57 for enabling a comfortable and ergonomic activation of the screw bit mechanism 7 via a corresponding finger of the hand of the user of the tool 3 according to the present invention. The finger receiving portion 57 preferably comprises a protuberance extending beyond a peripheral layout of the tool handle 1, preferably at a rear portion of the tool handle 1, as better shown in FIG. 1, said protuberance being preferably provided with a series of corresponding transversal ribs 59 for facilitating a better grip of said finger receiving portion 57. The screw bit mechanism 7 preferably comprises a support portion 33 for receiving at least one corresponding screw bit 31 intended to be used for carrying out tasks similar to those of screwdrivers and the like, such as screwing fasteners (screws, etc.) into drywall and other like surfaces. The screw bit mechanism 7 is preferably configured so that its support portion 33 and corresponding screw bit 31 are preferably retracted and lodged within the tool handle 1, as better shown in FIGS. 9-11, when the screw bit mechanism 5 is operated into the retracted configuration.

As can be easily understood by a person skilled in the art when referring to the accompanying drawings, the tool handle 1 as briefly explained herein and exemplified in the accompanying drawings, could be used with a variety of different tools, and thus, the blade 5 or other component used with the tool handle 1 can be various, depending on the particular applications for which the resulting tool 7 is intended for, as also apparent to a person skilled in the art.

Moreover, as also exemplified in the accompanying drawings, the tool handle 1 is preferably provided with a corresponding bore 67 extending through the tool handle 1, for enabling to hang the tool 3 onto a corresponding hook or other suitable support structure, such as a construction belt, and the like. Thus, the screw bit mechanism 7 according to the present invention is preferably configured accordingly, as can be easily understood by a person skilled in the art, so as to enable the provision of such a bore 67 extending to said tool handle 1.

Preferably also, and as exemplified in the accompanying drawings, the tool handle 1 comprises different slanted edges and portions, as well as curved portions, so as to enable for a more comfortable, secured and ergonomic hand grip of the tool handle 1, and thus of the resulting tool 3.

Preferably also, the inner core of the tool handle 1 may be provided with corresponding ribs, flanges, shoulders, and/or recesses, for appropriately receiving the screw bit mechanism 7 and for sustaining the corresponding loads to which the resulting tool 3 and/or handle 1 thereof may be subjected to, as apparent to a person skilled in the art.

Thus, the tool handle 1 and resulting tool 3 according to the present invention preferably comprise an attractive design. As previously explained, the tool handle 1 is preferably provided with an elastomeric and/or rubberized material, to provide for a soft grip ergonomic handle. As also previously explained, the logo and colors used for the handle 1 may be various and interchangeable for allowing the manufacturing of different tools 3 depending on different trademarks used, so as to properly represent the manufacturers, distributors, wholesalers, or other parties involved in the commercialization and selling of the tool 3. As aforementioned, the tool 3 according to the present invention is provided with a novel tool handle 1 provided with an innovative screw bit mechanism 7, preferably intended for gypsum screws and the like, configured to be assembled on any type of blade or other component for assembling the resulting tool 3.

As previously explained, and as illustrated in the accompanying drawings, the screw bit mechanism 7 is preferably intended to be opened or operated with a single hand allowing the user of the present tool 3 to have the other hand free for carrying out other tasks. The screw bit mechanism 7 is also preferably configured so as to be used either by left-hand users or right-hand users, and thus, as can be appreciated from the accompanying drawings, is preferably intended to be substantially symmetrical along a given plane of the tool 3. Furthermore, the opening or activation of the screw bit mechanism 7 can easily be carried out with a corresponding finger of the user, such as a thumb, the index, and/or other. As can also be easily understood by a person skilled in the art, the screw bit mechanism 7 is also preferably provided with resilient means, such as a spring for example, integrated into the screw bit mechanism 7 so as to keep the same, and more particularly the screw bit 31 thereof, in an elevated or extended configuration when operated into the operating configuration.
