The present embodiments described herein are generally directed to ladders and scaffolds. More specifically, the present embodiments herein pertain to portable work platforms.
There are great needs for a portable platform support system designed to provide a stable and safe working platform with variable working heights, especially for working on boats. During the repair or cleanup of a boat superstructure, and particularly during body work such as waxing, it often arises that workers need easy, safe access to the upper part of the boat structure. By the way of example, when cleaning a superstructure of a boat, it is often very difficult to clean the top portion of the structure owing to the fact that no convenient platform or other means is provided giving the worker proper access. This difficulty can be particularly pronounced in the case of taller boats. In attempting to work on hard-to-reach areas such as upper area of the superstructure, workers may cause damage to other portions of the boat or may cause injury to themselves.
Currently, working on the surface of the superstructure of a boat has been done with step ladders and scaffolds. Conventional ladders are of limited utility in boat environments because step ladder rungs will normally be perpendicular to the boat superstructure surface, leading workers to turn their bodies to work on the boat structure while standing on the ladder platform. This will put workers in a very unnatural and unsafe position. Workers can certainly entertain the idea of employing scaffolding on the deck. However, this method is expensive and is not ideal on a narrow path like the boat deck between the structure and railing. Due to this narrow deck area between the superstructure and boat railing, some workers resort to suspending themselves from the top of the structure using a rope. These customary methods of working on high superstructure of boats have been found to be inefficient and unsafe. From the above, it is therefore seen that there exists a need in the art to overcome the deficiencies and limitations described herein and above.
The embodiments described herein provide a portable work platform system configured to be removably mounted on a railing of a boat, the system comprising a base support having a first base component, a second base component, a first top surface and a second top surface; a clamping mechanism connecting the first base component to the second base component and being configured to connect the base support to the railing; and at least two extendable support arm systems each having a first bottom end, a second bottom end, a first top end and a second top end. Each of the first bottom ends connects to the first top surface and each of the second bottom ends connects to the second top surface.

Additional features and advantages are realized through the techniques of the present invention. Other embodiments and aspects of the invention are described in detail herein and are considered a part of the claimed invention.
The recitation herein of desirable objects which are met by various embodiments of the present invention is not meant to imply or suggest that any or all of these objects are present as essential features, either individually or collectively, in the most general embodiment of the present invention or in any of its more specific embodiments.
The subject matter which is regarded as the invention is particularly pointed out and distinctly claimed in the concluding portion of the specification. The invention, however, both as to organization and method of practice, together with the further objects and advantages thereof, may best be understood by reference to the following description taken in connection with the accompanying drawings in which:
The present disclosure describes a portable work platform system that can, for example, be removably mounted to a boat railing, vary in height by utilizing the extendable support arm system, and provide a safe platform for an individual to stand on while cleaning, painting, or otherwise modifying a boat superstructure surface. While using the term “boat superstructure surface” to represent the application of the system described herein, any surface which could be otherwise hard to reach without this portable work platform system is also intended to be included in the term “boat superstructure surface.”
As shown in
The boat to be used with this system is typically in the 55 foot to 79 foot range. This size of boat may have narrow walkways between the railing and the boat superstructure surface, and therefore may not have enough room for a ground engaging work platform to be configured. The railing, which the disclosure is mounted to, is typically between about 6″ and about 18″ and the device can accommodate varying railing widths.
In
The attachment structure functions to (1) provide a secure and steady attachment to the boat railing and (2) to provide a wider base for the load to be distributed over when the device is in use. The base support 100 may be manufactured from marine grade aluminum graphite, HDPE, or any other suitable material known in the art. The clamping mechanism 200 may be a worm screw mechanism, a bolted joint mechanism, a bar clamp mechanism, or any other suitable clamping mechanism known within the art. The purpose of the clamping mechanism is to provide pretension to the base support, which secures the base support to the railing. The clamping mechanism can be made from steel, nickel, aluminum, or any other suitable material known in the art.
A worm screw mechanism is well known within the art, and can be used as a gear system to allow an individual to turn the worm shaft 201 clockwise which results in the following sequence of events: (1) the worm shaft 201 spins the worm 202 along its center axis; (2) the worm 202 spins the worm wheel 203 along its center axis, said axis being generally perpendicular to the worm 202; (3) the worm wheel 203 pulls the bolt 204; and (5) the bolt 204 pulls the bolt head 206, which in turn pulls the second base component 120 towards the first base component 110. The nut 205 is generally flush with the first side 122 of the second base component 120 and the bolt head 206 is generally flush with the second side 123 of the second base component. Thus, turning the worm shaft 201 counter clockwise reverses the prior course of events and results in the nut 205 pushing against the first side 122 and expanding the base components in order to, for example, dismount the base support 100 from the railing 010. The bolt must have at least one threaded portion. There must be a threaded portion to interface with the nut 205 allowing the nut to be torqued into place to secure the bolt to the second base component 120. Additionally there must be a threaded portion to interface with the worm wheel 203, wherein the worm wheel 203 has an inner hole that is threaded with a mating thread, allowing the spinning of the worm wheel to move the bolt 204 along its axis in a direction dependent upon the direction the worm shaft is turned. These threaded portions on the bolt can be the same thread size and extend from the first side 122 to the end of the bolt 204 past the worm wheel 203. Alternatively, the threaded portions can differ at the nut interface 205 and the worm wheel interface 203 depending on how much torque is desired for the base support 100.
The extendable support arm system 300 and generally horizontal work platform 400 may also be manufactured from marine grade aluminum, graphite, HDPE, or any other material known in the art. In embodiments, the extendable support arms comprise nested concentric square tubes, or nested concentric circular tubes. The inner tubes are able to be slideably adjusted and may utilize a gear rack system to lock the inner tube in place to provide an individual with a platform at the desired height. The extendable support arms may also use a pin system in order to lock the inner tubes in place. The pin system comprises holes at varying intervals of the inner tubes and a single corresponding set of holes on the outer tubes, wherein the inner tubes height can be locked in place by aligning the desired interval of the inner tube with the corresponding set of holes on the outer tube and locking a pin in place. These systems for adjusting extendable support arms are well known within the art.
