Abstract
Abstract The invention relate to a lighthouse or beacon construction characterized in that in order to isolate vibrations, the upper part of the construction is not in rigid connection with the lower part subject to forces which cause vibrations, but the construction is broken at a suitable height and the upper part is mounted on the lower part so that it is supported by slide rails, roll rails, wheels, a flexible or pivoted parallelogram mechanism or elastic poles, or a corresponding flexible mechanism, so that the lower part can move substantially horizontally in relation to the upper part while the upper part is maintained in substantially vertical position.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
149 words
A lighthouse or beacon construction comprising an upper part adapted to house light sources, crew rooms and the like, a lower part adapted to be driven into a sea bottom to fasten said construction to the sea bottom, said lower part including a single rigid frame member extending upwardly above the water line to support said upper part, connection members for connecting said upper part to said single member of said lower part in a non-rigid connection to permit said lower part to move substantially horizontally in relation to said upper part, said connecting means maintaining said upper part in a substantially vertical position when said lower part moves horizontally, said connecting means including spring means for centering said upper part in relation to said single member of said lower part, and restriction means coacting between said upper and lower parts for restricting horizontal movement of said upper part.
Claim 2
Dependent Claim
149 words
A lighthouse or beacon construction comprising an upper part adapted to house light sources, crew rooms and the like, a lower part adapted to be driven into a sea bottom to fasten said construction to the sea bottom, said lower part including a single rigid frame member extending upwardly above the water line to support said upper part, connection members for connecting said upper part to said single member of said lower part in a non-rigid connection to permit said lower part to move substantially horizontally in relation to said upper part, said connecting means maintaining said upper part in a substantially vertical position when said lower part moves horizontally, said connecting means including spring means for centering said upper part in relation to said single member of said lower part, and restriction means coacting between said upper and lower parts for restricting horizontal movement of said upper part.
Claim 3
Dependent Claim
80 words
A construction as claimed in claim 1, wherein said connecting means includes a plurality of vertically disposed poles having their upper ends connected to said upper part and their lower ends connected to said single member of said lower part, said poles being elastic to define said spring means to permit said poles to bend for maintaining said upper part in said vertical position and for centering said upper part in relation to said single member of said lower part.
Claim 4
Dependent Claim
55 words
A construction as claimed in claim 2, wherein said restriction means includes a ring connected to a lower portion of said upper part, said ring being disposed around said single member of said lower part in a spaced-apart relationship, whereby said ring abuts against said single member to restrict horizontal movement of said upper part.
Claim 5
Dependent Claim
32 words
A construction as claimed in claim 2, wherein shock absorber means are connected between said upper part and said single member of said lower part to absorb shocks of said upper part.
Claim 6
Dependent Claim
55 words
A construction as claimed in claim 1, wherein said restriction means includes a ring connected to a lower portion of said upper part, said ring being disposed around said single member of said lower part in a spaced-apart relationship, whereby said ring abuts against said single member to restrict horizontal movement of said upper part.
Claim 7
Dependent Claim
32 words
A construction as claimed in claim 5, wherein shock absorber means are connected between said upper part and said single member of said lower part to absorb shocks of said upper part.
Claim 8
Dependent Claim
32 words
A construction as claimed in claim 1, wherein shock absorber means are connected between said upper part and said single member of said lower part to absorb shocks of said upper part.
Claim 9
Dependent Claim
49 words
A construction as claimed in claim 1, wherein said connection means includes a plurality of vertically disposed poles having their upper ends pivotly connected to said upper part and their lower ends pivotly connected to said single member of said lower part to define a flexible pivoting parallelogram mechanism.
Claim 10
Dependent Claim
21 words
A construction as claimed in claim 8, wherein said spring means are disposed adjacent to said lower ends of said poles.
Claim 11
Dependent Claim
21 words
A construction as claimed in claim 8, wherein said spring means are disposed adjacent to said upper ends of said poles.
Claim 12
Dependent Claim
41 words
A construction as claimed in claim 1, wherein said connection means includes at least one of wheels moving on rails, grooved side rails and rool rails which are disposed between said upper part and said single member of said lower part.
Claim 13
Dependent Claim
29 words
A construction as claimed in claim 11, wherein said restriction means includes end stoppers coacting with said rails to define shock absorbers to absorb shocks of said upper part.
Claim 14
Dependent Claim
39 words
A construction as claimed in claim 1, wherein said spring means includes leaf springs horizontally disposed between said upper part and said single member of said lower part to define shock absorbers to absorb shocks of said upper part.
Claim 15
Dependent Claim
26 words
A construction as claimed in claim 13, wherein said restriction means includes rubber cushions and the like disposed on an inner surface of said upper part.
