Claims
- 1. A push pin hanger for supporting an object on a supporting surface comprising a rigid base having first and second opposite surfaces, said first surface conforming to said supporting surface, a first pin rigidly mounted in said base and extending from said first surface at an acute angle thereto in a plane normal to said first surface, and a second pin rigidly mounted in said base and extending from said second surface in said plane at an acute angle to said first surface, whereby the direction of extension of said second pin intersects said first surface at a point spaced from said first pin, the ends of said first and second pins away from said base being directed in opposite directions with respect to said base and being pointed for insertion in said supporting surface and said object respectively.
- 2. The hanger of claim 1 wherein said first surface is substantially flat, and said first and second pins are substantially parallel and extend substantially at a 75.degree. angle to the plane of said first surface.
- 3. The push pin hanger of claim 1 wherein said pins have blunt ends completely embedded in and fixedly held by said base, said base being of a die casting metal.
- 4. A mounting device adapted to suspend an article on a wall, comprising a base portion having a flat surface, hinge means having a hinge axis parallel to said flat surface and separating said base portion into first and second portions pivoted together at said hinge means, a hook extending from said first portion away from said flat surface, and means for mounting said second portion to a wall.
- 5. The mounting device of claim 4 wherein said mounting means comprises a pin having a blunt end completely embedded in and rigidly held by said first portion, and extending at an acute angle to said second flat surface in a direction toward said second portion.
- 6. The mounting device of claim 5 wherein said base portion is of a cast metal, said hinge means consisting solely of cast metal of said first and second portions.
- 7. The mounting device of claim 5 wherein said base portion is of a molded plastic, and said hinge means comprises a groove extending across said base portion between said first and second flat surfaces.
- 8. A push pin hook for suspending an object by means of a wire comprising a unitary base having a base portion with flat mounting surfaces and a contoured surface opposite said flat surface and a hook portion projecting from said contoured surface of said base portion, the projection of the end of said hook portion away from said contoured surface on said flat portion, in a first plane normal to said flat surface, being spaced in a given direction from the projection of the junction of said hook and base portions on said flat surface in said first plane, said contoured surface, when viewed normal to said first plane, having a smooth contour extending continuously in said direction from said hook portion to said flat portion at the edge of said base portion most remote from said junction, a pin having a blunt end completely embedded in and rigidly held by said base portion and a pointed end extending from said flat surface at an obtuse angle to said direction for holding said push pin hook on a wall with said flat mounting surface engaging said wall, said pin intersecting said flat surface at a point in a second plane normal to said flat surface and first plane, said second plane intersecting said first plane between said edge of said base member and said end of said hook portion, whereby, upon sliding of said wire along said wall in a direction opposite said given direction, said contoured surface smoothly guides said wire into engagement with said hook portion.
- 9. The push pin hook of claim 8 wherein said obtuse angle is 105.degree..
- 10. The push pin hook of claim 8 comprising a second pin having a blunt end completely embedded in and rigidly held by said base portion and a pointed end extending from said flat surface at an obtuse angle to said direction, said second pin intersecting said flat surface at a second point in said second plane, said first mentioned and second points in said second plane being equally spaced on opposite sides of said first plane.
- 11. A push pin article comprising a metallic base member having a flat wall engaging surface and a surface opposite said flat surface, and a pin having a blunt end completely embedded in and fixedly held by said base member and a pointed end extending through said flat surface, the axis of said pin extending through said opposite surface, and a layer of the material of said base member flowed substantially completely over said blunt end of said pin, said layer forming a convex projection on said opposite surface, said projection being aligned with said pin.
- 12. A push pin hanger for supporting an object on a supporting surface, comprising a rigid base having a first substantially flat mounting surface and a second surface opposite said first surface, a first pin having one end rigidly embedded in said base and the other end extending from said first surface at an acute angle thereto, and a second pin having one end rigidly embedded in said base and the other end extending from said second surface, the direction of extension of said second pin intersecting said first surface at a point spaced from said first pin, said other ends of said first and second pins extending in opposite directions away from said base and being pointed for insertion in said supporting surface and said object respectively, said first and second pins extending in parallel directions.
- 13. The hanger of claim 12 wherein the ends of said pins embedded in said base are blunt, and a layer of the material of said base is flowed substantially completely over the blunt end of one of said pins in said base, said layer forming a convex projection on the surface of said base through which the other pin extends.
- 14. The push pin of claim 12 wherein said base is of a die cast material, and the blunt end of the other pin is cast in said base.
- 15. The push pin hook of claim 8 wherein said base is thicker in the region thereof from which said pin extends that the region thereof where said hook portion projects from said contoured surface.
- 16. The push pin hook of claim 15 wherein said contoured surface, when viewed normal to said first plane, is smoothly convex in the region between said edge and the projection of the end of said hook portion on said contoured surface in said first plane.
- 17. The mounting device of claim 4 wherein said base portion is formed of a molded plastic material with said first and second portions being molded with said first and second flat surfaces at an angle to one another, whereby said first and second portions are biased to said first position.
- 18. The mounting device of claim 17 wherein said hinge comprises a groove extending at least between said first and second flat surfaces.
- 19. The push pin article of claim 11 wherein the sides of said pin at said blunt end are not enlarged with respect to the portions of said pin between said pointed end and said blunt end.
- 20. The push pin article of claim 11 wherein the edges of said pin at said blunt end form axially extending continuations in line with the sides of said pin between said blunt end and said pointed end.
