INVENTOR SUICHI/FO 561M170 ATTORNEE BUILDING-SLIP HAVING A RESILIENT SUPPORTING MEMBER This invention relates to a building-slip having a resilient supporting member for launching a ship easily which has been built on the building-slip in a clock.
In order to launch a ship 1 which has been built on a building-slip in a dock, it has heretofore been a customary expedient to use a lower wooden block 3 which is secured to the base 2 in a suitable manner and apply a liquid soap as well as grease or lard to the upper surface of the block 3. However, the use of such a launching system suffers various shortcomings, such as, that it requires a considerable degree of manpower for preparatory and rearrangement works for launching and in addition, a great deal of cost due to a large quantity of grease or lard and a liquid soap used.
Thus, it is an object of this invention to provide a buildingslip without shortcomings mentioned above.
Another object of this invention is to provide a building-slip provided with a flow friction scuff resistant coating over the contacting surface thereof.
Still another object of this invention is to provide a buildingslip having a resilient supporting member characterized in that the resilient supporting member consisting of a synthetic resin sliding plate integrally secured to the upper surface of a resilient material, such as rubber is mounted on and fixed to the lower wooden block secured to the base.
These and other objects will bocome apparent from the following description taken in conjugation with the accompanying drawings in which:
FIG. 1 is a vertical sectional view of the building-slip of the first embodiment of the invention, the building-slip is supporting a ship.
FIG. 2 is an enlarged partially sectional view of the principal portion shown in FIG. 1.
FIG. 3 is an enlarged partially sectional view of the fixed portion ofthe resilient supporting member.
F l0. 4 is a top plan view of the resilient supporting member, and
F IG. 5 is a vertical sectional view showing the building-slip of the second embodiment of the invention.
Referring now to the drawings, FIG. 1 to 4 inclusive illustrate the first embodiment of the invention. Resilient strip formed of a rubber or the like, comprises an attaching intermediate thin wall portion 4, attaching side thin wall portions 5 and a supporting thick wall portion 6.
A sliding plate 7 formed of a low friction scuff resistant synthetic resins such as polytetrafluoroethylene is integrally bonded to the upper surface of the supporting thick wall portion 6 by adhesives or the like, thus the resilient supporting member 8 is constituted. The member 8 is placed on the lower wooden block 3 and metallic strip washers 9 are placed on the thin wall portions 4 and 5.
Then, the member 8 is secured to the lower wooden block 3 by setscrew 10 being screwed through the washer 9 and thin wall portions 4 and 5 into the lower wooden block 3. An upper wooden block 11 supporting a ship is placed on the upper surface of the sliding plate 7.
At one side and on upper surface of the lower block 3, guide 12 for guiding the direction of the movement of the upper wooden block 11 is fixed thereto by an angle member 13 and also the lower wooden block 3 is fixed to the base 2 bya similar angle member 14.
FIG. 5 illustrate the second embodiment of the invention in which, a metallic retainer 15 is secured to the lower wooden block 3 by setscrews l0 and formed with grooves 16 at its upper surface. The lower portions of the resilient supporting member 8 consisting of the sliding plate 7 similar to that in the first embodiment and resilient strip 17 such as rubber integrally secured to the lower surface thereof is engaged in the grooves 16 respectively and is bonded thereto for example as by adhesives or the like.
Examples of such rubber are soft rubber or hard rubber containing fibers therein.
With such arrangement noted above, even though there are an appreciable unevenness of the upper surface of the lower wooden block or an appreciable irregularity in thickness of the upper wooden block, it can adjust automatically them by difference in compressibility of the resilient material such as rubber to slide a ship easily on the sliding plate and launch one with the bottom of the ship being supported uniformly over it's full length, and the resilient supporting member once installed thereon can be used repeatedly as a permanent structure, so that grease, lard or liquid soap applying work at every launching and rearrangement work after that can eliminated, whereby a remarkable reduction in manpower for launching and a great economy in cost can be obtained.
