Cl. 312-244 4 Claims ABSTRACT OF THE DISCLOSURE An assembly having a carrying cover slidably interfitting with a base to which a power tool is removably mounted, the base being apertured for admitting a working element of the attached tool and for mounting work guiding fences. The base and cover are each U-shaped and assembled in complementary inverted right angular relation, the base having rigid peripheral stabilizing flanges facilitating assembly of the cover for housing the tool.
This invention concerns a combination carrying case and toolholder for portable power tools.
A principal object of this invention is to provide an improved combination carrying case and toolholder assembly to which a portable power tool is mounted in working posture and which affords firm support for a workpiece.
Another object of this invention is to provide an inexpensive assembly of the above described type which is of simplified, compact construction.
A further object of this invention is to provide an as sembly of the type described which is conditioned for use by bodily removing a cover member from a base member and simply inverting the base member.
Still another object of this invention is to provide an assembly of the type described which may be either free standing or secured to a supporting surface.
Other objects will be in part obvious and in part pointed out more in detail hereinafter.
The invention accordingly consists in the features of construction, combination of elements and arrangement of parts which will be exemplified in the construction hereafter set forth and the scope of the application which will be indicated in the appended claims.
In the drawings:
FIG. 1 is an isometric view of a preferred embodiment of a combination carrying case and toolholder of this invention in assembled relation;
FIG. 2 is an enlarged isometric view of the carrying case and toolholder shown partly disassembled;
FIG. 3 is an isometric view showing a base member in inverted exploded relation to a workpiece guide and a supporting surface; and
FIG. 4 is an isometric view of another type of tool mounted on the base member shown on a reduced scale.
Referring to the drawings in detail, a preferred embodiment of a combination carrying case and toolholder assembly for portable power tools is shown. The assembly 10 comprises only two sheet metal parts including a base 12 and a cover 14, the base 12 being of a sufiicient- 1y heavy gauge sheet material to provide a rigid member.
In the specific illustrated embodiment of this invention, the base 12 and cover 14 are both of simplified U- shaped construction particularly suited for quick and easy assembly in complementary inverted right angular relation to provide an enclosure for a portable saber saw, sander or similar power tool such as the router shown at 15 for purposes of illustration.
The cover 14 includes a bridge 16 and a pair of depending legs 18 shown releasably connected to the base 12 "ice with any suitable device such as the spring biased thumb latch 20 mounted on each leg 18 for engaging tongue and button elements 22 fixed to the base 12. The bridge 16 of the cover 14 is provided a carrying handle 24 for transporting the assembly 10.
The base 12 comprises a pair of opposed legs 26 connected by a flat bridge 28. A tool mounting shoe 30 is removably attached to an interior face of the bridge 28 by screws 32 driven home flush with an exterior face or work surface 33 of the base 12. The tool 15 is thus removably secured within the base 12 and can be utilized interchangeably as either a hand held or operatively mounted tool. When the cover 14 has been removed and set aside, the base 12 can be simply inverted to present the work surface 33 in a generally horizontally upwardly oriented posture. A relatively large tool admitting aperture 34 is provided in the bridge 28, and a suitable work element such as the saw blade 35 of the illustrated saber saw 15a (FIG. 4) then can be quickly installed. Appropriate guide fences such as 36 (FIG. 3) and 36a (FIG. 4) may be adjustably fixed to the bridge 28 at a number of convenient locations through suitable apertures such as at 38 in the bridge 28, if needed and the assembly 10 is conditioned for use.
So that a single flat piece of sheet material bent along two fold lines can be used to provide the cover member 14 in accordance with another feature of this invention, rigid peripheral stabilizing flanges such as shown at 40 are integrally formed on the base 12 at right angles to the bridge 28. The aforementioned tongue and button element 22 is preferably mounted on the flange 40 which is also shown apertured at 42 for receiving an auxiliary work guiding fence, not shown, particularly adapted for use With a router shaper tool.
Additionally, the legs 26 of the base 12 are each provide-d with integral peripheral flanges 44, 46 and 48 along their respective vertical and horizontal edge portions. The vertically extending flanges 44 and 46 of each leg 26 are preferably permanently joined to the bridge flanges 40, as with spot welds 50, and cooperate to provide a confining skirt portion for surface-to-surface engagement with the legs 18 of the cover 14 during storage and transport.
The horizontally extending flanges are turned inwardly at right angles toward each other from the ends of the legs 26 and have openings 52 for receiving fasteners 53 detachably securing the base 12 to a supporting surface of a table 54, if desired, to provide a toolholder which is more secure than when the base 12 is free standing. Opposite ends of the flanges 48 terminate adjacent the vertical flanges 44, 46 of the base 12 and provide a guide abutment 56 adjacent flanges 44 and 46 for slidably receiving the legs 18 of the cover 14 within the confining skirt portions of the base 12. Thus, a mounted router 15 or other portable power tool such as the saber saw 15a and their respective fences 36 and 36a and other accessories may be readily housed in the base 12 which is releasably locked to the cover 14, ensuring secure assembly, transport and storage of the combination carrying case and toolholder assembly. In addition, the flanges 48 afford bearing support for the bridge 16 of the cover 14 in assembled condition.
The assembly of this invention thus provides both a compact and convenient tool mounting support, which is sufficiently rigid to provide a practical work surface, and a tote case removably mounting and completely enclosing a standard power tool and its accessories. By virtue of the above described construction, the base alone need only be flanged and the cover may be formed simply along two fold lines to ensure economical manufacture and ease of assembly and disassembly.
As will be apparent to persons skilled in the art, various modifications and adaptations of the structure above described will become readily apparent without departure from the spirit and scope of the invention, the scope of which is defined in the appended claims.
1. A two-piece combination carrying case nad toolholder assembly for portable power tools comprising a U-shaped base, and a separable carrying cover of inverted U shape, the separable cover being slidably movable relative to the base during assembly and disassembly, the base and cover including locking means releasably securing the same in complementary mutual right angular relation and providing a closed assembly for housing a power tool, the base and cover each including a pair of legs and a bridge spanning the legs, the legs of the base each having rigid peripheral flange means formed thereon directed toward the other leg and including horizontally extending flange means disposed in underlying lapped relation to the bridge of the cover when the cover is assembled on the base, the horizontally extending flange means providing guide abutment means engageable with the legs of the cover when assembled and upon being slidably moved relative to the base during assembly and disassembly.
