2. Description of Related Art Including Information Disclosed Under 37 CFR 1.97 and 1.98
In the construction industry, there is a recurring need for measuring, marking, and cutting tools for use in connection with planar materials such as drywall. In practice, there are individual tools, such as large drywall squares, that are available which accomplish the various tasks required to mark, cut and finish a sheet of material. The problem lies in the fact that the requirement to use various individual tools is cumbersome and time consuming by the user to finish the particular task at hand.
U.S. Pat. No. 6,763,603 issued to Carrabino concerns a tape scriber formed as an integral device, either molded or cast, that includes a base portion, having a cavity formed therein, for accommodating the tab end of the tape. The base portion includes a laterally extending stem, having a slot there through, and into which a box cutter may locate its razor tip, in preparation for cutting of a board during usage. A rearwardly extending member includes an inclined slot, or at least a slot which accommodates a pencil upon an incline with the tip of the pencil extending through a bottom aperture, aligning under the precise end of the tape, to furnish a scribe or pencil mark at that location, as the rule is moved, to the exact dimension measured on its tape during usage.
U.S. Pat. No. 6,931,734 issued to Elder et al. discloses an implement alignment and guide system that comprises a tool which is adapted to be used in conjunction with a measuring tape to enable a worker to make accurate alignment marks while engaging in the art of carpentry, drywall, insulation and so forth.
The U.S. patent to Kim, U.S. Pat. No. 6,694,622, discloses a combination measuring, marking and cutting tool that comprises a housing, a measuring tape extendable from the housing, a ferrule attached to the free end of the measuring tape, an aperture formed in the ferrule, and a T-shaped pivot tab secured to the housing in proximity to the measuring tape.

DETAILED DESCRIPTION OF THE INVENTION
Referring to the drawings and particularly to FIG. 1, one form of the apparatus of the invention for measuring, marking and cutting a panel “P”, such as a sheet of drywall having an upper surface “S”, is there shown. The apparatus of the invention is used in combination with a conventional tape measure “TM” having a housing “H” and a self-recoiling measuring tape “T” extendible from the housing. The elongate measuring tape, which has a slight upward transverse curvature, typically retractably unrolls from a slot in the housing. At its distal end, the tape is provided with a short metal tab “MT” (FIG. 2) that serves the dual function of preventing the free end of the steel tape from entering the housing of the tape measure through the slot in the housing when retracted and providing the user of the tape measure with a means of conveniently grasping the free end of the tape when manipulating the tape.
The apparatus of the present form of the invention comprises three major components, namely a tape measure encasement assembly 20 for encasing a portion of the tape measure housing “H”, a clip assembly 22 adapted to be releasably connected to the distal end of the measuring tape and a cutting assembly 24 that is adapted to be releasably connected to the clip assembly.
Considering first the novel tape measure encasement assembly 20, as best seen in FIGS. 1 and 10 of the drawings, this novel assembly includes a base assembly 26 comprising a platform assembly 28 having a downwardly extending guide segment 28a and an encasement assembly 30 that is connected to platform assembly 28 by conventional fasteners 32 (FIG. 10). As best seen in FIG. 10, encasement assembly 30 includes a base wall 34, a sidewall 36 connected to base wall 34 and an end wall 38 that is also connected to base wall 34. End wall 38 includes a top wall portion 40 and a downwardly extending flange portion 44. A yieldably deformable retaining clip 46 is connected to top wall portions 40 and is constructed and arranged to engage the housing of the tape measure when the housing is in position within the encasement assembly 30 in the manner shown in FIG. 1 of the drawings. Also forming a part of the encasement assembly 30 is a retainer 48 that is pivotally connected to base wall 34 for movement between a first position shown by the solid lines in FIG. 11 where the extremity of the retainer is in engagement with the housing of the tape measure and a second lowered position shown by the phantom lines in FIG. 11.
Forming a part of the platform assembly 28 of the encasement assembly is the important roller wheel assembly 50 of the invention for measuring the travel of the tape measure encasement relative to the panel “P”. The details of construction and operation of this important lower wheel assembly will be discussed in the paragraphs that follow.
Referring particularly to FIGS. 1, 2 and 3 of the drawings, the previously identified clip assembly 22 of the invention, which is releasably connected to the distal end of the measuring tape, can be seen to comprise a hollow housing 52 having a front wall 54, a top wall 56 connected to the front wall, a rear wall 58 connected to the top wall and a pair of spaced apart side walls 60 that are also connected to the top wall in the manner shown in the drawings. For a purpose presently to be described, top wall 56 is provided with a slot 56a and each of the side walls 60 is provided with a cavity 60a.
As best seen in FIG. 3 of the drawings, a novel tape securement clip assembly 62 is connected to the rear wall 58 of the housing 52 for releasably securing the hollow housing to the measuring tape “T” of the tape measure. The construction and operation of the securement clip assembly will presently be described.
Releasably connected to the clip assembly 22 is the previously identified cutting assembly 24 that here comprises a sheath structure 64 that is uniquely designed to carry a cutting instrument such as a conventional, readily commercially available box cutter “BC” (FIG. 2). When the cutting instrument is seated within the sheath structure 64 in the manner illustrated in FIG. 2, the cutting blade “CB” of the cutting instrument extends downwardly from the bottom wall of the sheath structure. When the sheath assembly 24 is mated with the clip assembly 22 in the manner illustrated in FIGS. 5 and 6 of the drawings, the cutting blade is received within the slot 56a formed in the clip assembly housing 52 and extends downwardly into cutting engagement with the panel “P”.
Sheath assembly 24 includes a pair of spaced apart connector members 66 that are pivotally connected to the housing 68 of the sheath assembly in the manner illustrated in FIGS. 6 and 8 of the drawings. Each of the connector members 66 has an end portion 66a and each is movable about a pivot pin 67 from a first retracted position shown in FIG. 8 of the drawings into a second gripping position shown in FIG. 6 of the drawings. When the connector members are in the second gripping position, the end portions 66a thereof are receivable within the cavities 60a formed in said side walls of said clip assembly.
In using the apparatus of the invention, the retainer member 48 of the tape measure encasement assembly 20 is first moved into its lowered position and the housing “H” of the tape measure is positioned within the encasement assembly 30. This done, the retainer member is moved into its upper position so as to securely lock the housing of the tape in position within the encasement assembly 30.
Next, the clip assembly 22 is interconnected with the distal end of the tape in the manner illustrated in FIG. 8 of the drawings. This step is accomplished by gripping the upper extremities 70a of the locking arms 70 of the tape securement clip assembly 62 and moving them inwardly against the urging of the torsion pin assemblies 72 which interconnect the locking with the rear wall of the clip assembly (see FIG. 3). This inward movement of the upper extremities of the locking arms 70 causes the lower tape engaging extremities 70b of the locking arms to separate, permitting the tape “T” to pass between the extremities 70b. Upon the release of the upper extremities of the locking arms, the torsion springs 72a of the torsion pin assemblies 72 (see FIG. 3A) will urge the lower tape engaging extremities 70b of the locking arms into engagement with the lower surface of the tape (see FIG. 6).
With the clip assembly 22 connected to the distal end of the tape, the downwardly extending guide segment 28a of the platform assembly 28 can be positioned against the edge of the panel to be cut in the manner illustrated in FIG. 1 of the drawings. Next, the tape “T” can be withdrawn from the housing “H” to a distance corresponding to the location at which the panel is to be scored (for example, see the dotted line 85 in FIG. 1). With the clip assembly in the correct position, the cutting assembly 24 can be mated with the clip assembly in the manner previously described. If the workman is right-handed, the cutting assembly will be mated with the clip assembly in the manner shown by the solid lines in FIG. 1. Conversely, if the workman is left-handed, the cutting assembly will be mated with the clip assembly in the manner shown by the phantom lines in FIG. 1.
With the apparatus in the position illustrated in FIG. 1 of the drawings, the scoring operation can be commenced by simultaneously moving the tape measure encasement assembly 20 and a cutting assembly 24 longitudinally of the panel. As the tape measure encasement assembly 20 moves longitudinally of the panel, the previously identified roller wheel assembly 50 of the invention will measure the travel of the tape measure encasement relative to the panel. The roller wheel assembly 50, which is of a conventional construction, comprises roller 88 that is rotatably carried by platform 26. Roller 88 is mechanically coupled with a counter 90 that is also carried by platform 26 and includes indicia 89 that is visible through a window 92 provided in the platform (See FIGS. 10-15).
Turning now to FIGS. 16 through 19, an alternate form of the apparatus of the invention for measuring, marking and cutting a panel “P”, such as a sheet of drywall having an upper surface “S”, is there shown (see FIGS. 18 and 19). This latest form of the apparatus of the invention is similar in many respects to the embodiment of FIGS. 1 through 15 and like numerals are used in FIGS. 16 through 19 to identify like components. The primary difference between this latest form of the invention and the earlier described invention resides in the fact that the invention here includes a novel operating assembly 102 that is formed as a single unit and comprises a combination clip assembly and cutting assembly. As before, the apparatus of this latest form of the invention is used in combination with a conventional tape measure “TM” having a housing “H” and a self-recoiling measuring tape “T” extendible from the housing. The elongate measuring tape, which has a slight upward transverse curvature, typically retractably unrolls from a slot in the housing. At its distal end, the tape is provided with a short metal tab “MT” (FIG. 16) that serves the dual functions of preventing the free end of the steel tape from entering the housing of the tape measure through the slot in the housing when retracted and providing the user of the tape measure with a means of conveniently grasping the free end of the tape when manipulating the tape.
The apparatus of this latest form of the invention comprises two major assemblies, namely a tape measure encasement assembly 20 for encasing a portion of the tape measure housing “H” and the previously identified operating assembly 102 that is adapted to be releasably connected to the distal end of the measuring tape. Tape measure encasement assembly 20 is substantially identical in construction and operation to that previously described in connection with the first embodiment of the invention and comprises a base assembly 26, including a platform assembly 28 having a downwardly extending guide segment 28a and an encasement assembly 30 that is connected to platform assembly 28. Forming a part of the platform assembly 28 of the encasement assembly is the important roller wheel assembly 50 of the invention, for measuring the travel of the tape measure encasement relative to the panel “P”.
Referring particularly to FIGS. 16 and 17 of the drawings, the novel operating assembly 102 of the invention, which can be releasably interconnected with the distal end of the measuring tape, can be seen to comprise a hollow housing 104 having a front wall 104a, a top 104b connected to the front wall, a rear wall 104c connected to the top 104b, a pair of spaced apart side walls 104d that are also connected to the top wall and a bottom wall 104e that is connected to the side walls in the manner shown in the drawings. For a purpose presently to be described, top 104b is provided with a top opening 107 (FIG. 17) and each of the side walls 104d is provided with a tape receiving opening 109.
As best seen in FIG. 17 of the drawings, a tape securement assembly 112 is pivotally connected to the side walls 104a of the housing 104 for releasably securing the measuring tape “T” of the tape measure to the hollow housing. The construction and operation of the securement clip assembly will presently be described.
Removably disposed within the top opening 107 of the operating assembly 102 is a cutting instrument such as a conventional, readily commercially available box cutter “BC” (FIGS. 16 and 17). When the cutting instrument is seated within the opening and between the side walls 104d in the manner illustrated in the drawings, the cutting blade “CB” of the cutting instrument extends downwardly from the bottom wall 104e of the operating assembly through a slot 115 (FIG. 17) and into cutting engagement with the panel “P”.
The previously identified tape securement assembly 112 here includes a pair of spaced apart side walls 116 that are pivotally connected to the side walls 104d of the operating assembly in the manner illustrated in FIGS. 16 and 17 of the drawings. Each of the side walls is provided with a tape receiving opening 119 for releasably gripping the tape when the securement assembly is pivoted about pivot pins 120 into the gripping position shown in FIG. 17. In this regard, in operating the apparatus of the invention, the securement assembly is pivoted about the pivot pins from the first retracted position shown in FIG. 16 of the drawings into a second tape gripping position shown in FIG. 17 of the drawings. When the tape securement assembly is in the second gripping position, one side of the tape “T” is positioned within the tape receiving openings 119 and is urged into clamping engagement with the bottom portions of the tape receiving openings formed in side walls 104d of the operating assembly. As illustrated in FIG. 17, a coil spring 122 which is mounted between the front wall 104a and a finger engaging member 124 that is connected to and spans the side walls 104d, continuously urges one side of the tape receiving openings 119 into clamping engagement with the bottom portions of the tape receiving openings 119 (see FIG. 17).
In using the apparatus of the invention with the operating assembly in the configuration shown in FIG. 16 of the drawings and with the housing “H” of the tape measure positioned within the encasement assembly 30, the distal end of the tape is inserted into the openings 109 formed in the sidewalls of the operating assembly. This done, by gripping the finger engaging member 124, the tape securement assembly 112 is rotated from the first position shown in FIG. 16 to the second tape locking position shown in FIG. 17 so as to lockably interconnect the distal end of the tape with the operating assembly.
With the operating assembly 102 connected to the distal end of the tape, the downwardly extending guide segment 28a of the platform assembly 28 can be positioned against the edge of the panel to be cut in the manner illustrated in FIGS. 18 and 19 of the drawings. Next, the tape “T” can be withdrawn from the housing “H” to a distance corresponding to the location at which the panel is to be scored (for example see the dotted line “DL” in FIG. 18). If the workman is right-handed, the operating assembly will be mated with the distal end of the tape in the manner shown in FIG. 18. Conversely, if the workman is left-handed, the operating assembly will be mated with the distal end of the tape in the manner shown in FIG. 19.
With the apparatus in the position illustrated in either FIG. 18 or FIG. 19 of the drawings, the scoring operation can be commenced by simultaneously moving the tape measure encasement assembly 20 and operating assembly 102 longitudinally of the panel. As the tape measure 20 moves longitudinally of the panel, the previously identified roller wheel assembly 50 of the invention will, in the manner previously described, measure the travel of the tape measure encasement relative to the panel.
Turning next to FIGS. 20 through 28 and particularly to FIG. 20, yet another form of the apparatus of the invention for measuring, marking and cutting a panel “P” is there shown and generally designated by the numeral 126. This latest form of the apparatus of the invention is similar in some respects to the embodiment of FIGS. 1 through 19 and like numerals are used in FIGS. 20 through 28 to identify like components. The primary differences between this latest form of the invention and the earlier described invention resides in the differently configured operating assembly 128 and the differently configured tape measure encasement assembly 130. As before, the apparatus of this latest form of the invention is used in combination with a conventional tape measure “TM” having a housing “H” and a self-recoiling measuring tape “T” extendible from the housing.
Considering first the differently configured tape measure encasement assembly 130, this novel assembly comprises a base assembly 132, including a base 134 having a top wall 136 for supporting the measuring tape and a pair of spaced apart side walls 138 (see FIGS. 24 through 27). Base 134 also has first and second end portions 134a and 134b and a central portion 134c portion. Additionally, base 134 has a longitudinally extending track 140 that is disposed between side walls 138 (FIG. 24). For a purpose presently to be described, a scoring wheel 142 is connected to and extends downwardly from second end portion 134b (FIGS. 20 and 26).
Base assembly 132 further includes a roller wheel assembly support 146 that is receivable within the track 140 of base 134 in the manner shown in FIG. 25. As will later be described, roller wheel assembly support 146 is slidably movable within track 140 for movement between the first position shown in FIG. 25 to a second position and, also, to a third position to enable arcs and circles of different sizes to be scored onto the panel being worked on. Roller wheel assembly support 146 includes a downwardly extending guide segment 148 and a downwardly extending pivot pin 150 that is movable relative to the roller wheel assembly support between a first downwardly extending position shown by the solid lines in FIG. 25A and a second, upwardly folded retracted position shown by the phantom lines in FIG. 25A. The previously discussed roller wheel assembly 50 of the invention for measuring the travel of the tape measure encasement relative to the panel “P” is carried by the roller wheel assembly support 146 in the manner illustrated in FIGS. 24 and 25.
Considering now the operating assembly 128 of this latest form of the invention, this assembly, which can be releasably connected to the distal end of the measuring tape, comprises a hollow housing 154 including a top 156 having a top opening 156a for receiving a box cutter “BC” and a pair of spaced apart side walls 158 that are connected to top 156 (FIG. 22). As before, each of the spaced apart side walls has a tape receiving opening 158 formed therein. The operating assembly 128 also includes a bottom wall 160 that is connected to the side walls and a securement assembly 112 that is connected to the side walls in the manner shown in FIG. 22 of the drawings. Securement assembly 112 is substantially identical in construction and operation to the tape securement assembly 112, previously described in connection with the last described embodiment of the invention.
Receivable within top opening 156a of top 156 is an adapter assembly 162 for mounting therewithin a selected implement, such as the marking implement “MI” shown in FIG. 21. Adapter assembly 162 comprises a sleeve 164 having an open end portion 164a that is closable by a sliding cover 166 and a lower portion 164b that includes a locking tab 168 that is grippable by the securement assembly 112 so as to hold the adapter assembly 162 in position, in the manner depicted in FIG. 23. It is to be understood that various types of implements, including pens, pencils and the like can be mounted within adapter assembly 162.
In using the apparatus of this latest form of the invention in the manner illustrated in FIG. 28 to form arcuate scores “SC” and circles of different sizes onto a work piece, the securement assembly 112 is first appropriately manipulated so that the distal end of the tape can be removed from the side walls of the operating assembly. This done, the roller wheel assembly support 146 of the tape measure encasement assembly is moved along the track 140 of base 134 until the locking pin receiving aperture 170 formed in the inboard portion of the roller wheel assembly support 146, which removably receives a locking pin 171, is aligned with a selected one of three locking pin receiving apertures 172, 174 and 176 formed in base 134 (FIGS. 24-27). For example, to produce a score of an intermediate size, the locking pin 171 is removed and the roller wheel assembly support 146 is slidably moved within track 140 between the first position shown in FIG. 25, wherein the locking pin receiving aperture 170 is aligned with locking pin receiving aperture 172 to a second position, wherein the locking pin receiving aperture 170 is aligned with locking pin receiving aperture 174. To produce a score of a larger size, the roller wheel assembly support 146 is slidably moved within track 140 from the second position to a third position wherein the locking pin receiving aperture 170 is aligned with locking pin receiving aperture 176 so that the locking pin 171 can be inserted into apertures 170 and 176. With the locking pin 171 inserted into aperture 170 and into a selected one of three locking pin receiving apertures 172, 174 and 176 formed in base 134, the tape measure encasement assembly 130 is positioned on the panel in the manner illustrated in FIG. 28. Next, in order to score the panel along the arc “SC”, the pivot pin 150 is pressed into the panel and the tape measure encasement assembly 130 is rotated about the pivot pin in the direction of the arrow 180 of FIG. 28 so that the scoring wheel 142 cuts into the surface of the panel.
Having now described the invention in detail in accordance with the requirements of the patent statutes, those skilled in this art will have no difficulty in making changes and modifications in the individual parts or their relative assembly in order to meet specific requirements or conditions. Such changes and modifications may be made without departing from the scope and spirit of the invention, as set forth in the following claims.
