Abstract

The marine grab bar of the present invention is intended for use on a boat wherein a passenger needs a gripping post when standing. The grab bar assembly includes a base mounted to a wall or upright surface in the boat, and a telescoping bar moveable between a lower retracted storage position and a raised extended gripping position. A lock is provided in the assembly for retaining the bar in the raised position relative to the base.

Description

BACKGROUND OF THE INVENTION

It is common for a passenger in a boat to stand while the boat is moving, particularly when the operator or driver is also standing. The smoothness of the ride depends upon the water conditions and the skill of the driver. While the driver has the boat's steering wheel to grip while standing, which helps the driver's balance, many boats do not have any handle or other object for gripping by the standing passenger, for instance, when the boat hits a wave, or there is a sudden change in movement in the boat, such as a change of direction, acceleration, or deceleration.
Therefore, a primary objective of the present invention is the provision of a boat grab bar for use by a standing passenger in a moving boat.
Another objective of the present invention is the provision of a telescoping boat grab bar which can be moved between raised and lowered positions.
A further objective of the present invention is the provision of a boat grab bar which can be locked in an extended use position for grasping by a person and which can be retracted to a non-use position.
Still another objective of the present invention is the provision of a boat grab bar which slidably mounts within a base secured to an upright wall or surface of the boat.
Yet another objective of the present invention is the provision of a boat grab bar which is economical to manufacture, easy to install, and durable in use.
These and other objectives will become apparent from the following description of the invention.

BRIEF SUMMARY OF THE INVENTION

The boat grab bar of the present invention includes a tubular base which is mounted to a substantially vertical surface of the boat, such as side wall of the steering console, such that the base is oriented in an upright position. The base includes mounting flanges adapted to receive mounting hardware to secure the base to the boat surface. The bar is telescopically mounted within the base for movement between a lower retracted storage position and a raised, extended gripping position. A spring biased detent is provided for locking the bar in the raised position relative to the base. The upper end of the bar is covered by a cap, which limits the downward movement of the bar relative to the base.

BRIEF DESCRIPTION OF THE DRAWINGS

FIG. 1 is a perspective view of a boat having the grab bar of the present invention, and showing the grab bar in the retracted lower position.

FIG. 2 is a view similar to FIG. 1 showing the grab bar in an extended raised position.

FIG. 3 is an exploded view of the components of the grab bar assembly of the present invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

A boat is generally designated in FIGS. 1 and 2 by the reference numeral 10. The boat 10 includes a driving console 12 with a steering wheel 14 for the boat operator. While a flat style boat is shown in the drawings, it is understood the present invention can be used with many different types of boats.
The present invention is directed towards a grab bar assembly 16. The assembly 16 includes a base 18 which is mounted to a substantially vertical surface of the boat, such as the side wall 20 of the console 12. The base 18 includes mounting flanges or arms 22 at opposite ends of the base, which are adapted to receive mounting hardware for securing the assembly 16 to the wall or vertical surface 20. Screws (not shown) or other mounting hardware may be extended through holes 24 in the flanges 22 so as to mount the base 18 to the wall 20.
The assembly 16 further includes a bar 26 which is slidably mounted within the base 18 so as to be telescopically moveable between a retracted lower position, shown in FIG. 1, and an extended raised position, shown in FIG. 2. Preferably, when the bar 26 is in the retracted position, the upper end of the bar is at an elevation below the top surface 28 of the console 12, which defines an upper edge of the wall 20. The bar 26 resides above the top surface 28 of the console 12 when moved to the raised position, so as to be easily grasped by a person standing next to the console 12. The upper end of the bar 26 includes a cap 30, which limits the downward movement of the bar 26 relative to the base 18. The cap 30 also provides a gripping area or surface for raising the bar 26 to the extended position. As an alternative to the cap 30, the upper end of the bar 26 may be provided with an enlarged area or other projection which will preclude the upper end of the bar 26 from being pushed downwardly beyond the upper end of the base 18.
A lock member 32 is provided in the grab bar assembly 16 so as to lock the bar 26 in the raised position relative to the base 18. As best seen in FIG. 3, the lock member 32 preferably is in the form a spring biased detent or slide pin which fits within the hollow bar 26. The lock member 32 includes a flexible U-shaped spring 34 having opposite ends with a button or tab 36 on each end. The bar 26 includes a hole 38 extending therethrough, with the buttons 36 protrude outwardly through the hole 38 beyond the outer surface of the bar 26. The base 18 includes a hole 40 extending therethrough. When the hole 38 of the bar 26 is aligned with the hole 40 in the base 18, the buttons 36 automatically spring outwardly into retentive engagement with the hole 40 so as to lock the bar 26 in the raised position. The base 18 may be provided with one or more additional holes 42 for releasable retentive engagement by the buttons 36 when the bar hole 38 is aligned therewith, so as to lock the bar in an intermediate position between the raised and lowered positions. A person can easily depress the buttons 36 so as to allow the bar 26 to be moved from a locked position when desired.
In use, the bar 26 can be stored in the lowered, retracted position, and raised to the extended position when needed for gripping by a boat passenger. A person can simply pull up on the upper end of the bar 26 until the lock or detent 32 engages the desired hole 40, 42 in the base so as to retain the bar 26 in a selected position. Similarly, a person can manually depress the spring buttons 36 on the lock member 32 and then push downwardly on the bar cap 30 to move the bar from a locked position to the retracted position.
From the foregoing, it can be seen that the present invention accomplishes at least all of the stated objectives.
