Abstract

A universal socket tool includes a housing having a square internal chamber which is open at a lower end thereof. An array of square pins is suspended in sliding relation in the chamber with the lower ends of the pins arranged for engagement with a plurality of different fastening elements. Selected pins include tapered lower ends for engagement with a slotted screw heads. The pin suspension system includes upper and lower plates mounted in spaced relation in the chamber. The plates have aligned apertures for slidably receiving the upper ends of the pins. A flange at the top of each pin is positioned above the upper plate and a lower end of each pin is located below the lower plate. Each pin is provided with a spring disposed around its upper end for returning the pins to their normal position after disengaging the fastening element. In a second embodiment of the universal socket tool, the suspension system includes a plurality of retainer elements and a plurality of springs each having a first end secured to the upper end of a corresponding pin and a second end secured to the retainer element. In a third embodiment of the universal socket tool, the suspension system includes an adhesive medium received in the chamber, and a plurality of springs each having a first end respectively secured to the upper end of a corresponding pin and a second end imbedded in the adhesive.

Claims

1. A universal socket tool comprising:

a rigid housing including a longitudinal chamber, said chamber having a closed upper end and an open lower end;

a plurality of pins each having upper and lower ends, said pins being longitudinally oriented in said chamber wherein said lower ends of said pins are positioned adjacent said lower end of said chamber for engagement with a fastener element;

a plurality of springs each having first and second ends;

means for securing said first ends of said springs to said upper ends of said pins; and

a layer of adhesive material fixed to the upper end of the chamber, said second ends of said springs being imbedded in said layer of adhesive material whereby said pins are suspended for longitudinal movement within said chamber.

2. In the universal socket tool of claim 1, said means for securing said first ends of said springs to said upper ends of said pins comprising an upwardly extending head on each of said upper ends of said pins, said first ends of said springs being received over said heads on respective pins.

3. In the universal socket tool of claim 2, each of said heads including a reduced dimension neck portion adjacent said upper end of said pin.

4. In the universal socket tool of claim 1, said adhesive medium comprising a synthetic resin.

5. In the universal socket tool of claim 1, said pins including selected side-by-side pins having tapered lower end portions.

6. A universal socket tool comprising:

a rigid housing including a longitudinal chamber, said chamber having a closed upper end and an open lower end;

a plurality of pins each having upper and lower ends, said pins being longitudinally oriented in said chamber wherein said lower ends of said pins are positioned adjacent said lower end of said chamber for engagement with a fastener element, said upper ends of said pins each including an upwardly extending head portion supported by a reduced dimension neck portion;

a plurality of coil springs each having first and second ends, said first ends of said springs being secured to the head portions of respective pins;

a retainer element received in the upper end of said chamber, said retainer element including a plurality of downwardly extending head portions supported by a reduced dimension neck portion, said second ends of said springs being secured to the head portions of said retainer element whereby said pins are suspended for longitudinal movement within said chamber; and

means for securing said retainer element in said upper end of said chamber.

7. In the universal socket tool of claim 6, said means for securing said retainer element comprising an opening extending laterally through said retainer element, and a mounting rod extending through said opening, said mounting rod being secured to said housing.
