Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
153 words
A mounting plate for use in conjunction with (a) devices to be attached to said mounting plate, said devices including openings to receive fastening screws, the centre-to-centre distances of said openings being whole multiples of a predetermined modulus e (b) fastening screws for attaching said devices to said mounting plate, said screws having a predetermined diameter φ; said mounting plate including a plurality of rectangular holes each of the same dimensions and defining cross-members between neighbouring holes, the spacing (p) of neighbouring rectangular holes being the smallest value which satisfies all of the conditions that: (i) (p) is the product of modulus e and an odd number not less than 3; (ii) (p) is greater than the sum of modulus e and one-and-a-half times the diameter φ of the screws; and (iii) (p) is such that the width of each cross member is not less than half the diameter φ of the screws.
Claim 2
Dependent Claim
153 words
A mounting plate for use in conjunction with (a) devices to be attached to said mounting plate, said devices including openings to receive fastening screws, the centre-to-centre distances of said openings being whole multiples of a predetermined modulus e (b) fastening screws for attaching said devices to said mounting plate, said screws having a predetermined diameter φ; said mounting plate including a plurality of rectangular holes each of the same dimensions and defining cross-members between neighbouring holes, the spacing (p) of neighbouring rectangular holes being the smallest value which satisfies all of the conditions that: (i) (p) is the product of modulus e and an odd number not less than 3; (ii) (p) is greater than the sum of modulus e and one-and-a-half times the diameter φ of the screws; and (iii) (p) is such that the width of each cross member is not less than half the diameter φ of the screws.
Claim 3
Dependent Claim
85 words
A mounting plate, as claimed in claim 1, wherein said spacing of neighbouring rectangular holes is selected to permit holes of the mounting plate to receive (i) screws having a first diameter φ in openings of a device in which the centre-to-centre distances of said openings are whole multiples of a first modulus e, and (ii) screws having a second diameter φ in openings of at least another device in which the centre-to-centre distances of said openings are whole multiples of a second modulus e.
Claim 4
Dependent Claim
28 words
A mounting plate, as claimed in claim 1, wherein said spacing of neighbouring rectangular holes is 15 mm., and wherein said width of said cross-members is 4 mm.
Claim 5
Dependent Claim
23 words
A mounting plate, as claimed in claim 3, wherein said rectangular holes are square, and modified in that each alternate cross-member is removed.
Claim 6
Dependent Claim
49 words
A mounting plate, as claimed in claim 1, having a portion bounded by an edge thereof bent, at 90° to the plane of the remainder of the plate, along a line coinciding with the median axis of symmetry of a series of said openings next adjacent to said edge.
