Abstract: A base member of a push pin is formed by casting or molding, and a pin is inserted pointed end first into a hole in the base member and forced through the base member until the end opposite thereof lies below the surface of the base member. The material of the base member is then flowed over the end of the pin, by mechanical or heat techniques, to form a substantially complete layer over the end of the pin within the base member. The pins preferably extend at an acute angle to a flat surface of the base member. The push pin may have pins extending from opposite surfaces thereof, a loop shaped projection adapted to be affixed to a wire, or a hinge separating the base member into a hook portion and a portion carrying one or more pins. The push pin may have a contoured base member to facilitate the affixing of a picture wire to a hook formed on the base member. In another embodiment the push pin has a projection on the side thereof through which the pin extends, the projection having a rounded contour adjacent the pin, a radially outer surface, and an intermediate axially extending section between the rounded surface and the radially outer portion. The push pin may be formed with a pivoted lever, to serve as a wire clamp. For picture hanging purposes, the push pin may include a pair of pins extending from opposite sides of an elongated member and through projections, the elongated member having a saw tooth edge, with the planes of the saw tooth edge and the side of the elongated member adjacent thereto extending at an angle corresponding to portions of a nail extending at an angle in the wall, in order to facilitate the hanging of a picture on the wall.
Abstract translation: 推针的基座部件通过铸造或模制而形成，并且销钉首先插入到基座部件的孔中并被迫穿过基部部件，直到其相对的端部位于基部部件的表面之下。 然后，通过机械或热技术将基底构件的材料流过销的端部，以在基部构件内的销的端部上形成基本上完整的层。 销优选地以锐角延伸到基部构件的平坦表面。 推销可以具有从其相对表面延伸的销，适于固定到线的环形突起，或将基部构件分离成钩部和将承载一个或多个销的部分的铰链。 推销可以具有轮廓的基座构件，以便于将图画线固定到形成在基座构件上的钩子上。 在另一个实施例中，推销在其一侧具有突起，销延伸穿过该突起，突出部具有邻近销的圆形轮廓，径向外表面以及在圆形表面和径向外部之间的中间轴向延伸部分。 推销可以形成有枢转杆，用作线夹。 为了图像悬挂的目的，推销可以包括从细长构件的相对侧延伸并且通过突起的一对销，细长构件具有锯齿边缘，锯齿边缘的平面和细长构件的侧面 相邻的延伸部分以对应于在墙壁中以一定角度延伸的指甲的部分延伸，以便于将图片悬挂在壁上。
