ASSEMBLED FENDER UNIT DESCRIPTION This invention is concerned with fender units which are to be assembled in the field and to serve for the protection of piers, and the like from vessels docked alongside the same.
Referring to the accompanying drawings,
FIG. 1 is a cross-section of one form of the present invention.
FIG. 2 is a side view of the same form.
FIGS. 3 to 7 are cross-sections of further modifications.
And FIGS. 8 to 14 are cross-sections of assembled fender units according to the present invention.
The form of the present invention, shown in FIGS. 1 and 2, has a shock-receiver portion 1 composed of an elastic material like rubber or synthetic resin, in which.
a reinforcing piece 2 of iron or the like is embedded.
A fixture portion 3 is made of an elastic material like rubber or synthetic resin, which is also fortified with an embedded iron piece 4. The shock-receiver portion 1 and the fixture portion 3 are connected by and integral.
with an intermediate section made of an elastic material such as rubber or synthetic resin. The section 5 is inclined relative to the shock-receiver portion 1 and the fixture portion 3.
In the embodiment of FIG. 3, the section 5 extends on an incline from the right end of the fixture portion 3 in which the reinforcing piece 4 is embedded. The tip of the section 5, where the reinforcing piece 2 is embedded, serves as the shock-receiver portion 1.
In the embodiment of FIG. 4, the section 5 extends on an incline from about the midpoint of the fixture portion 3 where a reinforcing piece 4 is embedded. The shock-receiver portion 1 extends from the tip of the section 5 toward the right and within the shockreceiver portion 1 the reinforcing piece 2 is embedded.
In the embodiment of FIG. 5, the shock-receiver portion 1 has a reinforcing piece 2 embedded therein and the fixture portion 3 in which the reinforcing piece 4 is embedded, are joined near their midpoint by the slanting section 5.
In the embodiment of FIG. 6, the section 5 extends on an incline from the right end of the fixture portion 3 with the reinforcing piece 4 embedded therein. The right side of the section 5 forms a concave are 6 and the tip with the reinforcing piece 2 embedded therein, of the section 5 serves as the shock-receiver portion 1.
In the embodiment of FIG. 7, the section 5 extends on an incline from about the midpoint of the fixture portion 3 in which the reinforcing piece 4 is embedded. The right side of the section 5 forms the concave are 6, while the tip, where the reinforcing piece 2 is embedded, of the section 5 serves as the shock-receiver portion 1.
The fender units illustrated in FIGS. 1 to 7 are used in combination and assembled together with a shockreceiving board to the pier for protection of ships and piers.
To explain the assembly of the fender unit shown in FIGS. 1 and 2, the tips of shock-receiver portions 1, 1 of two fender units as shown in FIG. 8 are butted together and the fixture portions 3 together with the reinforcing pieces 4 are fixed to the pier 8 by means of anchor bolts 7. A shock-receiving board 9 is attached to the surfaces of shock-receiver portions 1, 1. The shockreceiving board 9 is fabricated of shape steel, iron plate, wood or hard synthetic resin. This board 9 is attached to the surfaces of the shock-receiver portions 1, 1 by fixing the board 9 to the reinforcing pieces 2, 2 by means of bolts.
In FIG. 9, the tips of shock-receiver portions 1, 1 of two fender units are separated and in this condition the fixture portions 3, 3 are fixed to the pier 8 by means of the anchor bolts 7, 7, with a single shock-receiving board extending over the shock-receiver portions 1, 1.
In FIG. 10, the two fender assemblies of FIG. 8 are arranged side by side and fixed to the pier 8, with a single shock-receiving board 9 extending over four shockreceiver portions 1.
In FIG. 11, on the outside of the fender assembly illustrated in FIG. 8 two other fender units with their shock-receiver portions 1 facing inward are fixed to the pier 8, with a single shock-receiving board 9 being attached extending over four shock-receivers 1, 1'.
In FIG. 12, the tips of shock-receiver portions 1, 1 of a fender assembly are butted together and fixed to the' pier 8. A joiner 10 is attached across the two shockreceiver portions 1, 1. Two other fender units are assembled with the tips of shock-receiver portions 1', l butted together. The shock-receiver portions 1', 1' are fixed to the joiner 10, and a single shock-receiving board 9 is attached over the fixture portions 3, 3.
In FIG. 13, two fender units are assembled with the tips of their shock-receiver portions 1, 1 separated from each other. The fixture portions 3, 3 are fixed to the pier 8. The joiner 10 is fitted across the shockreceiver portions 1, 1. Two other fender units are assembled with their fixture portions 3', 3' attached to the joiner 10. And a single shock-receiving board 9 is fitted extending over the shock-receiver portions 1', 1
In FIG. 14, the shock-receiving board 9 is attached to the pier 8. To the shock-receiving board 9 is connected an assembly of two fender units with their shock-receiver portions 1, l butted together. The joiner 10 is fitted across the fixture portions 3, 3. The fixture portions 3, 3' of another assembly of two fender units are attached to the joiner 10, with a shockreceiving board 9' fitted extending over the shockreceiver portions 1', l of the latter assembly.
This invention represents a unit of one shockreceiver portion 1 and one fixture portion 3 being joined by an elastic intermediate section 5. A plurality of units are assembled in the field with a shockreceiving board 9 and a joiner 10 to form a fender.
Unlike the conventional fender, this unit is compact and easy to manufacture or transport. Using such units, a variety of fenders of various sizes and various energy absorption capabilities can be built. The outstanding feature is that, whatever size the fender assembly may be, it can be easily built in the field.
Besides, the section 5 connecting the shock-receiver portion 1 and the fixture portion 3, which is an inclined elastic piece, can provide ample cushioning effect. Also the shock-receiver portion 1 and the fixture portion 3, with reinforcing pieces 2, 4 respectively embedded therein, have ample structural strength.
