Abstract
By providing a removable and repositionable panel member cooperatively mountable to a support panel in a plurality of alternate positions, which support panel is mountable to a machine tool, a unique, universally applicable safety shield is achieved. Preferably, the safety shield also incorporates a front panel pivotally mounted to the support panel, and constructed of cooperative mounted engagement of the removable and repositionable panel in a plurality of alternate positions therewith. If desired, a plurality of removable and repositionable panel members are employed to further enhance the alternate configurations obtainable using the safety shield of this invention.
Claims19
A safety shield for mounting to a machine tool which incorporates a non-rotating portion having a rotating cutting tool extending therefrom, said safety shield comprising:
- (A) a support panel mounted to the non-rotating portion of the machine tool and incorporating
- (1) aperture means for peripherally surrounding the rotating cutting tool, and
- (2) fastening means mounted along at least one side edge of the support panel;
- (B) a first panel pivotally mounted to the support panel;
- (C) a second panel
- (1) removably attached to the support panel,
- (2) selectively securable to the support panel in a plurality of alternate orientations and positions for extending the zone of protection afforded thereby to conform to the particular needs of the user, and
- (3) incorporating fastening alignment means formed therein along at least two sides thereof for cooperative interconnected engagement with the fastening means to assure secure mounting of the second panel to the support panel in any one of its selective positions;
- and:
- (D) cooperating fastening means
- (1) associated with the second panel and the support panel for securely mounting the second panel to the support panel in its alternate, selective positions, and
- (2) constructed for rapid engagement and disengagement with the fastening means of the support panel and the fastening alignment means of the second panel,
- whereby the second panel is quickly and easily mounted to the support panel in any one of a plurality of selective positions for effectively extending the zone of protection afforded by the support panel as required by the user.
A safety shield for mounting to a machine tool which incorporates a non-rotating portion having a rotating cutting tool extending therefrom, said safety shield comprising:
- (A) a support panel mounted to the non-rotating portion of the machine tool and incorporating
- (1) a substantially flat rectangular shaped member,
- (2) aperture means formed in the substantially flat rectangular member substantially at the midpoint thereof, for peripherally surrounding the rotating cutting tool, and
- (3) at least one threaded insert securely embedded in said flat rectangular shaped support panel substantially midway along each of two opposed side edges of said panel, in juxtaposed inwardly spaced relationship to the side edge thereof;
- (B) a first panel
- (1) pivotally mounted to the support panel, adjacent a third edge, positioned between said two, opposed insert carrying edges, and
- (2) incorporating a plurality of threaded inserts embedded in said first panel at various juxtaposed, cooperating, spaced positions thereabout;
- (C) a second panel
- (1) selectively securably mountable to both the support panel and the first panel in any one of a plurality of alternate orientations and positions, and
- (2) incorporating apertures
- (a) formed along two opposed edges of said panel in juxtaposed, inwardly spaced relationship to the terminating edges thereof, and
- (b) positioned for cooperative alignment with the threaded inserts of the support panel and the first panel, thereby extending the zone of protection afforded by the support or the first panel to conform to the particular needs of the user;
- and
- (D) fastening means
- (1) comprising an elongated screw means extending from an easily employed knob member for cooperative, associated, interconnection with the aperture means of the second panel and threaded engagement with the threaded inserts of the first panel and the support panel,
- thereby providing rapid engagement and disengagement of the second panel with the first panel and the support panel in any one of a pluraltiy of selected alternate positions and orientations for extending the zone of protection afforded by the support panel and the first panel to conform to the particular needs of the user regardless of the varying nature of these needs.
