Abstract
Abstract A drill guide assembly including a guide having a base with a predetermined transverse dimension and a plurality of guide channels formed therein in spaced apart relation wherein the transverse dimension of the base is sufficient to provide a linear path of travel of a drill bit passing therethrough and into a work piece. A positioning arm attachable at least one of two spaced apart points along the length of the base wherein the positioning arm has one end engaging the work piece so as to establish a predetermined angular orientation between the work piece and the base and particularly the drill passing through the base into the work piece.

Claim 1
Independent Claim
304 words
A drill guide assembly for directing a drill bit into a work piece at a predetermined relative orientation, said assembly comprising: guide means having a base and including a plurality of guide channels formed in said base, in spaced apart relation to one another and extending transversely through said base, the transverse dimension of said base and of each of said plurality of guide channels being sufficient to direct movement of a drill bit through any of said guide channels in a substantially linear path of travel into said work piece; shield means secured substantially adjacent one exterior surface of said base and including axis means disposed in aligned communicating relation to said plurality of guide channels and configured to allow passage therethrough of a drill bit into and through any one of said plurality of guide channels, said shield means formed from a material of sufficient hardness to resist penetration of the drill bit therein, positioning means movably secured to said base and disposed in supporting engagement between said base and the work piece and positioned to orient said base in angular orientation relative to the exposed working surface of the work piece, connecting means secured to at least point along the length of said base and movably engaging said positioning means so as to movably interconnect said base and said positioning means, whereby angular orientation between said base and the work piece varies as said positioning means is moved and reoriented relative to said base, said connecting means is positionable at either of at least two spaced apart points along the length of said base, and either of said aforementioned positions is connectable with said positioning means, said base disposed in reversed angular attitude relative to the work piece upon securing said positioning means with opposite of said two spaced apart points.
Claim 2
Dependent Claim
304 words
A drill guide assembly for directing a drill bit into a work piece at a predetermined relative orientation, said assembly comprising: guide means having a base and including a plurality of guide channels formed in said base, in spaced apart relation to one another and extending transversely through said base, the transverse dimension of said base and of each of said plurality of guide channels being sufficient to direct movement of a drill bit through any of said guide channels in a substantially linear path of travel into said work piece; shield means secured substantially adjacent one exterior surface of said base and including axis means disposed in aligned communicating relation to said plurality of guide channels and configured to allow passage therethrough of a drill bit into and through any one of said plurality of guide channels, said shield means formed from a material of sufficient hardness to resist penetration of the drill bit therein, positioning means movably secured to said base and disposed in supporting engagement between said base and the work piece and positioned to orient said base in angular orientation relative to the exposed working surface of the work piece, connecting means secured to at least point along the length of said base and movably engaging said positioning means so as to movably interconnect said base and said positioning means, whereby angular orientation between said base and the work piece varies as said positioning means is moved and reoriented relative to said base, said connecting means is positionable at either of at least two spaced apart points along the length of said base, and either of said aforementioned positions is connectable with said positioning means, said base disposed in reversed angular attitude relative to the work piece upon securing said positioning means with opposite of said two spaced apart points.
Claim 3
Dependent Claim
47 words
A drill guide assembly as in claim 1 wherein said axis means comprises a plurality of apertures each disposed in aligned communicating relation with one of said plurality of guide channels, said plurality of apertures and each of said correspondingly positioned guide channels having substantially equivalent dimensions.
Claim 4
Dependent Claim
30 words
A drill guide assembly as in claim 2 wherein a number of said plurality of apertures having different dimensional diameters each of which corresponds to a different size drill bit.
Claim 5
Dependent Claim
60 words
A drill guide assembly as in claim 1 wherein said positioning means comprises an arm element having a substantially elongated configuration, slot means integrally formed in said arm and extending along a predetermined length of said arm, said slot configured to have its peripheral portions slidingly engaging said connecting means to effect relative movement between said arm and said base.
Claim 6
Dependent Claim
202 words
A drill guide assembly for directing a drill bit into a work piece at a predetermined relative orientation, said assembly comprising: guide means having a base and including a plurality of guide channels formed in said base, in spaced apart relation to one another and extending transversely through said base, the transverse dimension of said base and of each of said plurality of guide channels being sufficient to direct movement of a drill bit through any of said guide channels in a substantially linear path of travel into said work piece; shield means secured substantially adjacent one exterior surface of said base and including axis means disposed in aligned communicating relation to said plurality of guide channels and cofigured to allow passage therethrough of a drill bit into and through any one of said plurality of guide channels, said shield means formed from a material of sufficient hardness to resist penetration of the drill bit therein, said shield means comprises two plate elements secured in oppositely disposed relation to opposite exterior surfaces of said base and extending along the length thereof in covering, protective relation to said surfaces of said base, both said plates structured to provide access to said guide channels.
Claim 7
Dependent Claim
202 words
A drill guide assembly for directing a drill bit into a work piece at a predetermined relative orientation, said assembly comprising: guide means having a base and including a plurality of guide channels formed in said base, in spaced apart relation to one another and extending transversely through said base, the transverse dimension of said base and of each of said plurality of guide channels being sufficient to direct movement of a drill bit through any of said guide channels in a substantially linear path of travel into said work piece; shield means secured substantially adjacent one exterior surface of said base and including axis means disposed in aligned communicating relation to said plurality of guide channels and cofigured to allow passage therethrough of a drill bit into and through any one of said plurality of guide channels, said shield means formed from a material of sufficient hardness to resist penetration of the drill bit therein, said shield means comprises two plate elements secured in oppositely disposed relation to opposite exterior surfaces of said base and extending along the length thereof in covering, protective relation to said surfaces of said base, both said plates structured to provide access to said guide channels.
