(913 Electric Ave., Seal Beach, Calif. 90740) Filed Sept. 6, 1966, Ser. No. 577,310 3 Claims. (Cl. 114108) The present invention relates generally to the art of boating and more particularly to a new and novel mounting device for removably attaching an extremity of a sail to the end of a spar.
Many smaller sailboats utilize a sail having a sleeve formed along its front edge, with such sleeve being telescopically received by a mast to removably secure the sail to such mast. With this arrangement the upper end of the sail sleeve tends to become Worn due to its abutment with the top of the mast. Additionally, the upper portion of the sail is provided with a rigid head board that is integral with the sail but independent of the mast. Such headboard tends to tilt relative to the mast whereby the upper portion of the sail does not assume an efiicient curvature.
It is a major object of the present invention to provide a mounting device for removably attaching the upper portion of a sail to the upper end of a mast in such a manner that the upper end of the sail is not worn by contact with the mast and additionally the upper portion of the sail is retained in an efiicient curvature.
Another object of the present invention is to provide a sail mounting device of the aforedescribed nature which is extremely simple in design and foolproof in operation.
An additional object of the present invention is to provide a sail mounting device of the aforedescribed nature that is rugged of construction and will provide a long service life.
Yet a further object of the present invention is to provide a sail mounting device of the aforedescribed nature that may be manufactured economically.
It is a more particular object of the present invention to provide a sail mounting device of the aforedescribed nature utilizing a tube having an inside diameter slightly larger than the diameter of the upper end of the mast, with the lower end of such tube being open. The upper end of the tube is provided with radially directed means that rest against the upper end of the mast. A pair of rearwardly directed, aligned ears extend from the rear edge of the tube with the facing surfaces of such ears defining a space that receives the upper portion of the sail.
It is yet another object of the present invention to provide a sail mounting device of the aforedescribed nature which may be employed to removably attach the foot of a sail to the free end of a mast boom.
These and other objects and advantages of the present invention will become apparent from the following detailed description, when taken in conjunction with the appended drawings wherein:
FIGURE 1 is a side elevational view showing a sail provided with a preferred embodiment of the present invention;
FIGURE 2 is a perspective view taken in enlarged scale and showing the details of a sail mounting device embodying the present invention;
FIGURE 3 is a vertical sectional view taken along line 33 of FIGURE 2;
FIGURE 4 is a vertical sectional view taken along lien 44 of FIGURE 3; and
FIGURE 5 is a top plan view of said sail mounting device.
Referring to the drawings, there is shown a sail S provided with a preferred embodiment of the present invention. The sail S is shown carried by a generally vertically extending mast 10 and a generally horizontal boom 12 that is pivotally attached to the lower portion of mast 10. Both the mast 10 and boom 12 are commonly termed spars. The front portion of the sail S is formed with an integral sleeve 14 defined by the material from which the sail is fabricated. The upper portion of the sail S is provided with a headboard H embodying the present invention, while the lower rear portion of the sail S is provided with a'footboard F embodying the present invention. It should be understood that the configuration of the headboard H and the footboard F may be generally similar.
More particularly, the headboard H includes a vertical extending split tube 20 having an inside diameter slightly larger than the outside diameter of the upper portion of the mast 10 and the thickness of the material from which sleeve 14 isformed whereby such tube may freely pivot relative to the mast 10 even in the presence of the sail sleeve 14. The lower end of the tube 20 is open. The upper end of the tube 20 is provided with a pair of radially inwardly directed tabs 22 and 24. The underside of these tabs 22 and 24 rest against the top of the mast 10 without interfering with pivotal movement of the tube 20 relative to such mast.
The tube 20 is open along its rear end. A pair of vertical aligned, rigid ears 26 and 28 integrally extend rearwardly from the two rear edges of the tube 20. The ears 26 and 28 are closely spaced with the facing surfaces of such ears 26 and 28 defining a vertical space 29 that receives the upper portion of the sail S. Such upper sail portion is afiixed within such space as by means of a plurality of rivets 30.
In the use of the aforedescribed headboard H, with the tube 20 disposed upon the upper portion of the mast 10, the tabs 22 and 24 will maintain the headboard H and therefore sail S upon the upper portion of the mast 10 while at the same time permitting the headboard to freely pivot relative to the mast. The ears 26 and 28 will support the upper portion of the sail S for several inches outwardly of the mast 10 to permit the upper portion of the sail to achieve a shape of maximum efiiciency.
As noted hereinbefore, the footboard F is generally similar in construction to the headboard H, the split tube 10' of the footboard F being telescopically received by the rear end of the boom 12. It will be understood that the lower edge of the sail S is formed with a sleeve 32 similar to the sleeve 14.
Preferably, both the headboard H and the footboard P will be of integral construction and formed of a cornparatively rigid synthetic plastic material. Other materials, however, having comparable qualities may also be employed.
Various modifications and changes may be made with respect to the foregoing detailed description, Without departing from the spirit of the present invention or the scope of the following claims.
1. A mounting device for removably attaching an extremity of a sail to the end of a spar, comprising:
a tube having an inside diameter slightly larger than the diameter of said end of said spar, one end of said tube being open;
3 radially directed retainer means extending across the end of said tube opposite said open end to rest against said end of said spar; and a pair of laterally directed, closely spaced and aligned, rigid ears extending from a longitudinal edge of said tube, the facing surfaces of said ears defining a space that receives said extremity of said sail. 2. A mounting device as set forth in-claim 1 wherein said tube is split along one end and said ears are integral lateral extensions of said one end.
3. A mounting device as set forth in claim 2 wherein said radially directed retainer means comprise a pair of tabs integrally extending from the sides of the open end of said tube.
