Abstract
Abstract An apparatus for installing, at the front end of an instrument panel, an aircraft instrument having a rectangular chassis. The installation occurs by advancing a screw through a corner adaptor, into the instrument. The adaptors are attached to the periphery of a rectangular hole in the instrument panel, after the instrument has been inserted therethrough, so as to create an octagonal hole as is typically found in instrument panels. The corner adaptors are made up of a first plate and a second plate having a spacer region which is slightly narrower than the thickness of the instrument panel. When a screw is inserted through the first plate and the second plate, they are held together and adhere to the instrument panel which is inserted therein.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
157 words
An aircraft instrument panel, of the type having aircraft instruments mounted therein, which have octagonally shaped bezels, the panel comprising: a. a planar panel member having a plurality of holes therein, for receiving aircraft instruments, at least one of said holes being rectangular in shape and thereby having four corners and being capable of receiving an aircraft instrument having a chassis with a rectangular cross-section, when the chassis is sectioned in a plane parallel to the planar panel member; b. a plurality of corner adapter means for insertion in the four corners of said rectangular hole so that the rectangular hole is transformed into an octagonal hole; c. each of said plurality of corner adapter means having a threaded hole therethrough for receiving a screw; d. a plurality of screws for insertion through said threaded holes and extending into said aircraft instrument; whereby, the rectangular hole in the aircraft instrument panel is transformable into an octagonal hole.
Claim 2
Dependent Claim
157 words
An aircraft instrument panel, of the type having aircraft instruments mounted therein, which have octagonally shaped bezels, the panel comprising: a. a planar panel member having a plurality of holes therein, for receiving aircraft instruments, at least one of said holes being rectangular in shape and thereby having four corners and being capable of receiving an aircraft instrument having a chassis with a rectangular cross-section, when the chassis is sectioned in a plane parallel to the planar panel member; b. a plurality of corner adapter means for insertion in the four corners of said rectangular hole so that the rectangular hole is transformed into an octagonal hole; c. each of said plurality of corner adapter means having a threaded hole therethrough for receiving a screw; d. a plurality of screws for insertion through said threaded holes and extending into said aircraft instrument; whereby, the rectangular hole in the aircraft instrument panel is transformable into an octagonal hole.
Claim 3
Dependent Claim
43 words
A panel of claim 1 wherein the corner adapter means comprises: a. a first plate for attachment to the aircraft instrument; b. a second plate for attachment to the panel member; and c. a screw connecting the first plate with the second plate.
Claim 4
Independent Claim
91 words
An apparatus for attaching an aircraft instrument having a rectangular chassis and an aircraft instrument panel having a rectangular hole therein said rectangular hole having four corners, said apparatus comprising: a. a plurality of mounting members detachably attached to the aircraft instrument at said corners of said rectangular hole; b. a plurality of adapter means detachably attached to the aircraft instrument panel, for transforming the rectangular hole therein into an octagonal hole; and c. a plurality of means for connecting said plurality of mounting members with said plurality of adapter means.
Claim 5
Independent Claim
91 words
An apparatus for attaching an aircraft instrument having a rectangular chassis and an aircraft instrument panel having a rectangular hole therein said rectangular hole having four corners, said apparatus comprising: a. a plurality of mounting members detachably attached to the aircraft instrument at said corners of said rectangular hole; b. a plurality of adapter means detachably attached to the aircraft instrument panel, for transforming the rectangular hole therein into an octagonal hole; and c. a plurality of means for connecting said plurality of mounting members with said plurality of adapter means.
Claim 6
Dependent Claim
41 words
An apparatus of claim 3, wherein the plurality of mounting members comprises: a. a plurality of first plates, each having a cylindrical depression therein; and a plurality of flexible washers disposed in the cylindrical depression in each of the first plates.
Claim 7
Dependent Claim
34 words
An apparatus of claim 4 wherein the plurality of adapter means comprises a plurality of second plates having a spacer region therein, the spacer region being narrower than the thickness of the instrument panel.
Claim 8
Dependent Claim
31 words
An apparatus of claim 5 wherein the plurality of means for connecting comprises a plurality of screws for insertion through the plurality of mounting members and the plurality of adapter means.
Claim 9
Independent Claim
162 words
An apparatus comprising: a. an aircraft instrument having a rectangular chassis; b. an aircraft instrument panel having a rectangular hole, with four corners, therein, for receiving said aircraft instrument; c. a plurality of panel mounting members detachably attached with said aircraft instrument panel, of said corners, for transforming the rectangular hole in said aircraft instrument into an octagonal hole; d. a plurality of mounting screws; e. a plurality of instrument members detachably attached with said aircraft instrument for connecting with said plurality of panel members by said mounting screws; whereby, the aircraft instrument, having a rectangular chassis, is inserted through the rectangular hole in the aircraft instrument panel and attached to the aircraft instrument panel by the interconnection of said plurality of instrument members, said plurality of panel members and said plurality of mounting screws; thereby the rectangular hole in the aircraft instrument panel is transformed into an octagonal hole and the aircraft instrument is securely received by said aircraft instrument panel.
Claim 10
Independent Claim
162 words
An apparatus comprising: a. an aircraft instrument having a rectangular chassis; b. an aircraft instrument panel having a rectangular hole, with four corners, therein, for receiving said aircraft instrument; c. a plurality of panel mounting members detachably attached with said aircraft instrument panel, of said corners, for transforming the rectangular hole in said aircraft instrument into an octagonal hole; d. a plurality of mounting screws; e. a plurality of instrument members detachably attached with said aircraft instrument for connecting with said plurality of panel members by said mounting screws; whereby, the aircraft instrument, having a rectangular chassis, is inserted through the rectangular hole in the aircraft instrument panel and attached to the aircraft instrument panel by the interconnection of said plurality of instrument members, said plurality of panel members and said plurality of mounting screws; thereby the rectangular hole in the aircraft instrument panel is transformed into an octagonal hole and the aircraft instrument is securely received by said aircraft instrument panel.
