Embodiment Construction

[0015] The following describes an apparatus and method for use in raising and lowering a sailboat mast. The sailboat mast includes a mast that is slideably mounted inside a base such that the mast telescopes into the base. A guide that is attached to the mast and has a plurality of teeth fits into a channel in the base. A gear mechanism that is attached to the base and operably connected to the teeth on the guide raises and lowers the sailboat mast.

[0016] A side view of a mast 107 having a guide 105 wherein the mast 107 is slideably mounted inside a base 103 having a channel 101 for the guide 105 is shown in FIG. 1. A rear view of the apparatus is shown in FIG. 2, while a cross-sectional view is shown in FIG. 3.

[0017] The channel 101 attached to the base 103 extends down the length of the base 103. A guide 105 attached to the mast 107 extends down the length of the mast 107. The mast 105 slideably fits inside the base 103 such that the guide 105 is accepted into the channel 101. T...

Abstract

An apparatus and method for use to raise and lower a sailboat mast are described. A channel (101) in a base (103) complements and is capable of receiving a guide (105) of a mast (107) that is slideably mounted inside the base (103). A gear (111) having a handle (113) is operably connected to a plurality of teeth (109) that run longitudinally down the length of guide (105). A bracket (115) attaches the gear (111) to the base (103). In an embodiment of the invention, a wheel (409) that is attached to bracket (413) engages a second guide (405) so as to support the mast (407) by acting to counter forces applied to and by the gear (111) during mast (407) raising and lowering.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS [0001] Not Applicable STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH / DEVELOPMENT [0002] The present invention does not involve any form of federally sponsored research or development. BACKGROUND OF THE INVENTION [0003] The present invention relates to sailboats, including, but not limited to, an extendable mast for use with different types of masts and varying sailing conditions. Devices and methods for raising and lowering masts, such as those commonly used for sailboats, are known. Sailboats operate under a variety of ambient conditions and for a variety of purposes. Weather conditions can include hot days that have low winds speeds or cold days with high wind speeds. Competitive sailing can demand high sailing speeds that require large and often special sails such as jibs, spinnakers, and so forth can be used. Pleasure sailing at slower speeds often requires smaller sails. Because of varying weather condition and multiple uses of a sailbo...
