DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

As depicted on FIG. 1, this multiple tool unit (1) includes a housing with two main compartments (2 and 3). The entire unit (1) is designed to be easily held in hand. These two compartments are the knife compartment (2) and the tape measure compartment (3). The knife compartment can incorporate features from a typical retractable knife readily available with a blade carriage (4), a blade carriage track (5), and a blade stop button (6). The retractable knife in this invention also includes additional features to increase safety associated with its use by including the automatic return of the blade to inside the knife compartment. As shown on FIGS. 10 and 11, the knife assembly in this invention also includes a resistance spring (34), notches on blade carriage (35), a spring loaded blade stop button (6) which engages one of the notches on the carriage (35), a blade slide button (36) which is accessible externally to knife compartment (2), and a blade carriage (4) which is magnetized to better hold the blade.

This invention further includes a means to access the knife compartment (3) as depicted in FIG. 4 via a hinge (7) or as a removable panel (not shown) A latch (12) is provided to allow a means to secure and open the panel which is attached via a hinge (7) to the tape measure compartment(3). The latch can include a spring (not shown) to maintain pressure on the door latch when closed and springing the door open when unlatched. The knife compartment is also designed with space for storing extra or used blades and can include a magnetic compartment divider (8) to hold the blades.

The knife compartment can also include a pencil holder (9), a surface allowing writing and erasing (10), and a blade slide adjustor (11) as depicted on FIG. 2.

The tape measure compartment (3) is designed to incorporate numerous tools in addition to a retractable spring loaded tape measure. As depicted on FIG. 1, the compartment (3) includes a tape spindle (13), a tape measure (14) and a brake (15). A sub-compartment (16) can be created on the bottom of compartment 2 to house various tools which can pivot around a pin (17) as required to allow their use. The tools in the sub-compartment (16) can include tools such as a carbine saw (18), flat head screwdriver (19), Phillips head screwdriver (20), multipurpose saw (21), and steel rule (22). Depending on the intended user, other tools (such as pliers, scissors, wrenches, flashlight etc.) can be substituted for these or added to these.

In addition such tools could be designed to be totally removable (i.e., no pin or removable from pin) from the sub-compartment (16) if desired.

Other tools which can be included in the design for the tape measure compartment (3) include: pencil sharpener (23) and associated shavings chute (24); hammer with two heads (25); bubble vials (26) for determining degree of plumb and level; pivoting scrapers (27) for scoring surfaces, removing grout, etc; pry hook (28); a belt clip (29), a multipurpose file (33), and a V-shaped wrench (37) on outer surface of compartment that flips out for use.

In another embodiment of this invention, a lamp is provided powered by battery (ies) located in the top compartment. The lamp can further be designed to swivel to point light where it is needed.

This multiple tool unit (1) is designed to be modified to suit an intended user. Thus one or both of the scrapers can be replaced with a glass/tile scoring wheel (38). Individual tools, in sub-compartment (16) can be replaced as desired. The entire multi-tool unit in sub-compartment (16) can be replaced by an entire new multiple tool sub-compartment unit as desired for a particular job.

The tape measure compartment as depicted in the drawings is designed with a removable panel/cover to access the compartment if needed. Screws (30) are one shown on the Figures to facilitate such access. The tape measure compartment can also be designed to allow writing and erasing by the user.

FIG. 9 further depicts a means to determine the angle between two surfaces by including a marker on a pivoting tool which is visible through an opening to point to the angle indicated on markings (31) on the outside cover of the compartment. To facilitate this as well as for accurate use of the bubble vials (26) for determining plumb and level, the tape measure compartment (3) is designed with at least one corner (32) being square.

The entire multiple-tool unit a compact unit designed for easy comfortable hand use.

The above description and accompanying Figures are examples of the present invention. The scope of the present invention is not limited by the exemplary embodiment. Other applications and variations of the present inventions will be obvious to a person skilled in the art. For example in lieu of the extendable V-shaped wrench, a magnifying glass, straight razor or small storage case could be included. The multiple-tool unit could also be designed to allow swapping one of these tools for another by including easy means for removal and replacement.
