Abstract
Abstract A circuit board anchor of the type which may be utilized to anchor the opposite ends of a circuit board in a circuit board mounting box, each anchor including an elongated beam formed with a central chamber opening to one side and having retainers at its opposite ends defining the opposite ends of such chamber. A snake shaped deformable strut is received in the chamber and is formed with a pair of humps projecting transversely from the open side of the chamber with such humps being deformable to further project from such chamber. An axial compressing device is mounted in one of the retainers and is operable to shift axially and compress the strut to deform such strut and further project the humps from such chamber to urge an adjacent circuit board against retaining structure formed by such box to frictionally hold such circuit board securely in position.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
198 words
A circuit board anchor for anchoring an extremity of a circuit board in a circuit board box and comprising: an elongated beam formed with an elongated chamber having a back wall and open on its front side; axial retainers on the opposite ends of said beam forming the end walls for said chamber; snake shaped deformable strut means projecting axially in said chamber and formed with a hump projecting from the open side of said chamber for engagement with said circuit board and having sufficient flexibility to flex upon axial compression thereof to flex said hump a predetermined distance transversely from said open side; and an axial compressing device mounted in one of said retainers and operable to compress said strut means axially inwardly to flex said hump transversely said predetermined distance whereby said beam may be positioned on one side of the margin of said end of said circuit board and said compression device operated to compress said strut means axially to urge said hump transversely outwardly to engage said circuit board and urge it away from said beam to force it against adjacent structure to anchor said end of said circuit board frictionally to said box.
Claim 2
Dependent Claim
198 words
A circuit board anchor for anchoring an extremity of a circuit board in a circuit board box and comprising: an elongated beam formed with an elongated chamber having a back wall and open on its front side; axial retainers on the opposite ends of said beam forming the end walls for said chamber; snake shaped deformable strut means projecting axially in said chamber and formed with a hump projecting from the open side of said chamber for engagement with said circuit board and having sufficient flexibility to flex upon axial compression thereof to flex said hump a predetermined distance transversely from said open side; and an axial compressing device mounted in one of said retainers and operable to compress said strut means axially inwardly to flex said hump transversely said predetermined distance whereby said beam may be positioned on one side of the margin of said end of said circuit board and said compression device operated to compress said strut means axially to urge said hump transversely outwardly to engage said circuit board and urge it away from said beam to force it against adjacent structure to anchor said end of said circuit board frictionally to said box.
Claim 3
Dependent Claim
79 words
A circuit board anchor according to claim 1 wherein said box is formed with pairs of opposed flanges spaced at predetermined spaces therealong and defining said adjacent structure and wherein: said beam is of sufficient width to, along with the thickness of said circuit board extremity, be received between adjacent flanges and said hump is projectable a sufficient distance transversely from said open side upon operation of said compression device to urge said card against the adjacent said flange.
Claim 4
Dependent Claim
57 words
A circuit board anchor according to claim 1 wherein: said beam is channel shaped to form said chamber and includes side walls having their iNtermediate portions cut back and taper outwardly away from said back wall adjacent said retainers; and said retainers are in the form of end wall means disposed at opposite ends of said chamber.
Claim 5
Dependent Claim
49 words
A circuit board anchor according to claim 1 wherein: said beam includes a side wall projecting from said back wall and turned inwardly to form a lip confronting said open side and spaced therefrom for receipt therebehind of said one extremity of said board to define said adjacent structure.
Claim 6
Dependent Claim
31 words
A circuit board anchor according to claim 1 wherein: said strut means is in the form of a leaf spring formed with a pair of humps projecting from said open side.
Claim 7
Dependent Claim
51 words
A circuit board anchor according to claim 1 wherein: said strut means is formed to have its opposite extremities engage said back wall, angles outwardly away from said back wall to form a pair of axially spaced apart transversely projecting humps and then turns back inwardly to form an intermediate depression.
Claim 8
Dependent Claim
92 words
A circuit board anchor according to claim 1 wherein: said strut means is in the form of a leaf spring having its opposite extremities abut said retainers, then angles outwardly away from said opposite extremities and away from said back wall and inwardly toward the axial center of said chamber to turn and project parallel to said back wall defining a pair of humps and then turns to angle inwardly toward said back wall to join and form a medial turn-back engaging said back wall to form a support intermediate said humps.
Claim 9
Dependent Claim
44 words
A circuit board anchor according to claim 1 wherein: one of said retainers includes an axially extending through, threaded bore; and said compression device is in the form of a screw screwed through said threaded bore and engaging the end of said strut means.
Claim 10
Dependent Claim
58 words
A circuit board anchor according to claim 1 wherein: one of said retainers is in the form of an end wall having a turned back hook holding one end of said strut means captive and the other retainer includes a fitting formed with a through, threaded bore; and said compression device includes a screw screwed through said bore.
Claim 11
Dependent Claim
19 words
A circuit board anchor according to claim 4 that includes: fastening means for fastening said beam to said box.
