Abstract

A peg or annunciator board device for offices and plants to indicate disposition of personnel. Aligned rows of pegs of lighttransmitting material which glow, when pressed inwards, from light from a source within the device. Automatic latching of a single peg or group of pegs when pressed inwards and individual or multiple peg release.

Claims

1. In a pegboard device including;

an enclosure having a front wall 11 with an inner surface, the wall having spaced holes 14 arranged in horizontal rows;

pegs having upper and lower ends, the pegs extending through the holes and being adapted for axial movement therethrough, normal to the front wall, from an outer position at which the upper end extends outwards a particular distance from the wall, to an inner latched position at which the outer end extends but a short distance outwards of the wall;

the device being constructed and arranged so tHat when a peg is moved inward from the outer position it latches at the inner position;

the device being characterized by a latch bar assembly 30 including in combination;

a. a frame 32 within the enclosure the frame including, a first lower member 33 a second lower member 34 end members 35 and the front wall 11, b. the first and second lower members having holes aligned with a particular hole of the front wall, so that each hole of the top wall is aligned with a pair of holes in the first and second lower members, for axial movement of the peg as aforesaid, c. each peg in its outer position passing through a hole of the first lower member but not through the aligned hole of the second lower member, d. each peg in its inner latched position extending through the aligned hole of the second lower member, e. a cam 38 secured to each peg, the cam having a base 39 disposed to face the inner surface of the front wall, f. a compression spring 40 surrounding each peg, the spring having an outer end in contact with an inner end of the cam, and a lower end in contact with the first lower member of the frame, so as to urge the peg to the outer position at which the cam base is held against the inner surface of the front wall, g. a latch bar 31 disposed transverse to the pegs of each horizontal row, the bar having an upper portion 42 and a lower portion formed to receive hinge pins 45, i. hinge pins secured in the frame end members 45, the latch bar being hinged to swing about the pins, ii. a tension spring 46 having an inner end secured to the first lower member, and an outer end secured to the latch bar, adapted to urge the latch bar upper portion against the cam, iii. the latch bar having means 44 adapted to engage the base of the cam as a peg is pressed inwards from the outer position aforesaid, and to latch the peg in the inner position, h. and means to unlatch a peg latched in the inner position.

2. Structure as defined in claim 1;

the cam having a truncated conical portion, with the base being a short cylinder;

the latch bar upper portion having a channel portion disposed hollow side inwards facing the pegs, an upper wall of the channel forming the latch bar latch means, which upper wall engages the upper surface of the cam base as the peg is moved inwards, so latching the peg as aforesaid.

3. Structure as defined in claim 2, the means to unlatch a peg being characterized by;

the channel having a lower wall disposed so that when a peg is moved inwards past the latched position, the cam conical portion contacts the lower wall of the channel and swings the hinged latch bar, thus disengaging latched pegs.

4. Structure as defined in claim 3, and means to adjust tension of the tension spring.
