A bracket providing an auxiliary support adapted for easy connection to or removal from a base structure having an opening opposite edge portions of which may serve as mounting means for the bracket. The bracket illustrated comprises a plurality of arm elements having a common pivot. One portion of the arm elements is adapted to serve as a support for an object to be appropriately mounted with reference to said base structure. Other portions of said arm elements provide two anchoring means the projected ends of which may be inserted in the opening in the base structure. Means are provided to induce a scissors-like spread of the inserted arm elements, to cause remote surface portions thereof to firmly engage said opposite edge portions of said opening, and to fix said arm elements in a predetermined relation to each other and to the base structure to which the bracket is mounted.
Bracket apparatus comprising at least two anchoring means pivotally mounted to adapt their projected end portions to be disposed in an opening between opposite edge portions of a base structure to which the bracket is intended to mount, means for inducing a scissors-like spread of said anchoring means to have remote portions thereof engage to the said opposite edge portions of said base structure, means defining a mounting device interconnected with said anchoring means and adapted to be supported thereby and in a fixed relation thereto, said anchoring means being formed by a plurality of arm-like elements having a common means to which they mount, a first portion of said arm-like elements providing one of said two anchoring means and mounting means extending in a sense transversely thereof and movable relative thereto which mounts in turn a device which is movable to and retractable from a further portion of said arm-like elements which forms a second of said anchoring means, said device providing said means for inducing said scissors-like spread of said anchoring means, being a screw and said transversely extending means being a pivot which is mounted for rotative movement in said first portion of said arm-like elements.
Bracket apparatus arranged to support a mounting device for an antenna or like object comprising at least two arm-like means pivotally related by pivot means and adapted thereby to position in an adjacent side by side relation or be pivotally adjusted in scissors-like fashion, said pivot means being positioned more remote from one end of said arm-like means than the other, means mounted to and extending laterally of one of said two arm-like means to normally dispose free of and in a sense transverse to the other of said two arm-like means, said laterally extending means being rotatably mounted to said one of said two arm-like means and being positioned intermediate the location of said pivot means and said one end of said one of said arm-like means and mounting in connection therewith means adapted to be variably projected therefrom to engage and apply pressure to said other of said two arm-like means when the ends of said two armlike means more remote from said pivot means are disposed in an opening between opposite edge portions of a base structure to which the bracket is intended to mount whereby to cause said arm-like means to be spread and forced into clamping relation with said opposite edge portions between which they are disposed.
Bracket apparatus comprising at least two arm-like means pivotally related by pivot means and adapted thereby to position in adjacent side by side relation or be pivotally adjusted in scissors-like fashion, means mounted to and extending laterally of one of said two arm-like means to normally dispose free of and in a sense transverse to the other of said arm-like means, said laterally extending means mounting in connection therewith means adapted to be variably projected therefrom to engage and apply pressure to said other of said two arm-like means when ends of said two arm-like means remote from their pivotal connection are disposed in an opening between opposite edge portions of a base structure to which the bracket is intended to mount whereby to cause said arm-like means to be spread and forced into clamping relation with said opposite edge portions between which they are disposed, said one of said arm-like means being comprised of a pair of arm-like elements having apertures therein which are adapted to be transversely aligned and sized to receive said laterally extending means, said laterally extending means providing a transversely disposed pivot which forms a bridge between said arm-like elements to provide for their conjoint pivoting movement with respect to said other of said two arm-like means.
Bracket apparatus comprising at least two anchoring means pivotally mounted to adapt their projected end portions to be disposed in an opening between opposite edge portions of a base structure to which the bracket is intended to mount, means for inducing a scissors-like spread of said anchoring means to have remote portions thereof engage to the said opposite edge portions of said base structure, means defining a mounting device interconnected with said anchoring means and adapted to be supported thereby and in a fixed relation thereto, said anchoring means being formed by a plurality of arm-like elements having a common means to which they mount, a first portion of said arm-like elements providing one of said two anchoring means and mounting means extending in a sense transversely thereof and movable relative thereto which mounts in turn a device which is movable to and retractable from a further portion of said arm-like elements which forms a second of said anchoring means, said device, providing said means for inducing said scissors-like spread of said anchoring means, being a screw which is projectable to and retractable from an arm element which forms said further portion of said arm-like elements and includes in an edge thereof adjacent said screw a recess in which said screw is adapted to seat to induce the pressured spread of the respective portions of said arm-like elements constituting said anchoring means.
Bracket apparatus comprising at least two arm-like means pivotally related by pivot means and adapted thereby to position in adjacent side by side relation or be pivotally adjusted in scissors-like fashion, means mounted to and extending laterally of one of said arm-like means to normally dispose free of and in a sense transverse to the other of said two arm-like means, said laterally extending means mounting in connection therewith means adapted to be variably projected therefrom to apply pressure to said other of said two arm-like means when ends of said two armlike means remote from their pivotal connection are disposed in an opening between opposite edge portions of a base structure to which the bracket is intended to mount whereby to cause said arm-like means to be spread and forced into clamping engagement with said opposite edge portions between which they are disposed, said one arm-like means comprising two lever-like arm elements having said other arm-like means disposed therebetween, at least in part, in the pivotal connection thereof thereto.
Bracket apparatus comprising at least two arm-like means pivotally related by pivot means and adapted thereby to position in adjacent side by side relation or be pivotally adjusted in scissors-like fashion, means mounted to and extending laterally of one of said arm-like means to normally dispose free of and in a sense transverse to the other of said two arm-like means, said laterally extending means mounting in connection therewith means adapted to be variably projected therefrom to apply pressure to said other of said two arm-like means when ends of said two arm-like means remote from their pivotal connection are disposed in an opening between opposite edge portions of a base structure to which the bracket is intended to mount whereby to cause said arm-like means to be spread and forced into clamping engagement with said opposite edge portions between which they are disposed, said variably projectible means being a screw-like device which is threadedly engaged with said laterally extending means and arranged to be projected therethrough to engage with and apply pressure to said other of said arm-like means.
