United States Patent O 3 495,565 POST INTENDEDFOR MOORING BOATS OR FOR ANALOGOUS PURPOSES Erik Verner Gustavii, 25 Bymarksgatan, 552 59 Jonkoping, Sweden Filed .lune 11, 1968, Ser. No. 736,207 Int. Cl. B631) 21/00; E02b 3/22 U.S. Cl. 114-230 3 Claims ABSTRACT OF 'IHE DISCLOSURE The present invention relates to a post for mooring a boat, for example.
Mooring posts should withstand the vertically acting forces of ice which forms in many harbors, instead of allowing these forces to act on the posts which is the disadvantage of most conventional mooring posts.
An object of the present invention is to provide a post intended for mooring a boat or for analogous purposes in which the above disadvantage is reduced or eliminated.
According to the present invention, there is provided a post for mooring boats and analogous purposes, the combination of a first part for implanting in a surface below the water level and a second part above the first part and cooperable therewith to be displaceable relative to said iirst part whereby when said first part is implanted so that said second part is capable of projecting above a water surface, a volumetric displacement of the portion of said second part below said water level is smaller than the total weight of said second part so that said second part drops to a predetermined position when a lifting force ceases.
The invention will now be described in more detail by way of example with reference to the accompanying drawings, in which:
FIGURE 1 is an elevation of one example of a post according to the invention, surrounded by ice, and
FIGURE 2 is a cross-section of another example of a post according to the invention.
1n both examples of the invention a mooring post comprises a portion 1, having a pointed lower end 2 so that it may be driven into the ground. Near the upper end of the portion 1 there is secured, by welding for example, an annulus 3 of flat or circular section. The section above the annulus is received in the bore of a tubular upper portion 5 of the post, the bore of which is of larger cross-sectional area than the lower portion 1 so that the upper portion 5 is capable of moving relatively to the lower portion 1 but the diameter of which is less than the diameter of the annulus 3.
The upper portion 5 is arranged to project above the surface level of water and is so dimensioncd that the ICC volumetric displacement of the parts situated below the surface of the water is smaller than its total weight.
If the upper portion 5 is frozen solid with ice in the winter, the upper portion 5 can move relatively to the lower portion 1 with vertical movement of the ice. After the portion 5 has been freed from the ice, for example when the ice breaks up, the portion 5 drops again to its planned position relative to the portion 1 implanted below the surface of the water.
To facilitate vertical movement of the upper portion 5, a helical spring 4, may be provided on the portion 1 seating on the annulus 3 and on which bears the lower end of the portion 5.
A mooring bracket is secured on the upper portion as shown at 7.
The invention may be modified within the scope of its principle as shown in FIGUR-E 2. Instead of employing a coil spring 4 resting on an annulus 3, the spring may be situated on the top of the portion 1 and within the upper tubular portion 5, which latter may be solid above the spring as shown in FIGURE 2. In a post of this kind, the portions 1 and 5 possess a core 8 and 9, respectively, which is sheathed with a tube 10 and 11, respectively, made of plastic material, for example. As shown, the upper portion has its lower part encased in a plastic tube 12 into which the lower portion is partially inserted. In this case, the spring 4 is situated within the tube 12 and on the top of the lower portion 1. The spring 4 and the bracket 7 may be coated with plastic material. The upper portion may be ballasted by means of a concrete core 13.
I claim:
1. A post for mooring boats and analogous purposes, comprising a first part for implanting in a surface below the water level, and a second part above said first part and cooperable therewith to be displaceable relative to said lirst part whereby when said first part is implanted so that said second part is capable to projecting above a water surface, a volumetric displacement of the portion of said second part below the water level is smaller than the total weight of said second part so that said second part drops to a predetermined position when a lifting force ceases.
2. The combination as claimed in claim 1, including resilient means operably related to said first and second parts for biasing said second part relative to said first part.
3. The combination as claimed in claim 2, wherein said resilient means is seated on annular means surrounding and secured to said first part.
