Patent Application
20210131128
The present invention generally relates to devices that may be attached to boards, studs, support beams to be used as a temporary step or support member. More specifically, the present invention includes a three sided, rigid structure for attachment to a support structure that includes a horizontal surface for use as a step, or for use as a support mechanism.
In the construction industry, it is often necessary for a worker to work at a height that may be out of reach while the worker is standing on a floor or on ground level. Traditionally, a worker may employ a step stool, a ladder, scaffolding, or the like, in order to reach the area where such work is required. However, ladders are heavy and cumbersome, take up a lot of space, and have caused countless accidents. Step stools are smaller and easier to use, but they are frequently of little value because of their limited height. Scaffolding is heavy, expensive and time consuming to erect, and occupies an enormous amount of space.
Therefore, it would be desirable to provide a small, lightweight structure that may be temporarily attached to framing in a house or building, such as a two by four stud, or the like, which is easy to install and remove, and which is not heavy, expensive or cumbersome. Efforts to develop such a structure or system have been attempted with varying degrees of success.
For example, the following references disclose several types of such devices, and each of the references below is hereby incorporated by reference herein, in their entireties.
U.S. Pat. No. 3,298,459 Tree Climbing Apparatus
This invention relates to apparatus for facilitating the climbing of trees and more particularly to tree climbing steps of the removable type particularly adapted for the use by sportsmen.
U.S. Pat. No. 4,696,372 Portable Step and Carrying Device for Stud Wall
A portable step-forming device releasably attachable to a vertical wooden stud comprises a U-shaped gripping member for closely receiving a stud member, a step member attached to one prong of the U-shaped member and further having an enlarged end for retaining the user's foot on the step member, and a gripping means comprising a spring-loaded reciprocable member with a stud-engaging end for holding the step-forming device in position of the stud member.
U.S. Pat. No. 3,561,563 Portable Post Step
An integral rigid catwalk metal sheet bent along a transverse fold line to provide a post engaging portion and a step portion, the post engaging portion having a laterally inwardly extending notch for engaging the post. The post is engaged by opposing edges of the notch wherein one of the edges is the inner edge portion of the step portion. The step is placed on the post from the side and the weight of the step portion will cause the unit to pivot downwardly bringing the opposing edges of the notch into engagement with the post thereby locking it in place. The post engaging portion forms an obtuse angle with the step portion and the step portion is normally positioned in a horizontal plane. A series of vertically spaced apart steps may be placed on a post and extend alternately from the post at angles of 90* to each other. Oppositely facing concave portions may be formed in the opposing edge portions for matingly engaging the rounded peripheral edge of a round post.
In accordance with one aspect of the invention, a first embodiment of a temporary step and support assembly includes two primary portions: an attachment member and a horizontal support surface. The attachment member preferably includes three sides for engaging a board or vertical support, wherein the first side and the third side are disposed in parallel relation, and the second side is preferably angled upwardly from the first side to the third side. The horizontal support surface, in a preferred embodiment, is attached to the first side of the attachment member, and serves as a temporary step, so that a user may attach the temporary step and support assembly to a vertical board for standing or climbing to reach a greater height in an upward direction.
The temporary step and support assembly may be attached to the board or support member in any suitable manner. In one embodiment, the first side of the attachment member may define a threaded opening for receiving a screw or bolt. Optionally, the third side of the attachment member may also define such a hole for receiving a screw or bolt. Alternatively (or along with other attachment means), one or more spikes or teeth may project from the first side and/or third side of the attachment member to temporarily secure the temporary step and support assembly to the vertical support.
A series of temporary step and support assemblies may be attached to one or more boards or supports in order to provide a temporary ladder or a series of steps for a user to climb in lieu of a ladder, scaffolding, or a step stool. It should be understood that the device may be used not only for a step, but for other tasks, such as a support for tools, a place to hang a tool bag, or for any other desired purpose.
These and other features, aspects, and advantages of the present invention will become better understood with regard to the following description, appended claims, and accompanying drawings where:
The present invention, in a first embodiment, includes a temporary step and support assembly 10 having two primary portions: an attachment member 12 and a horizontal support surface (or horizontal surface member) 14. The attachment member preferably includes three sides for engaging a board or vertical support 22 (such as a framing stud in home construction), wherein the first side 16 and the third side 20 are disposed in offset parallel relation to one another on opposite sides of a vertical support member 22, and the second side 18 is preferably angled upwardly from the first side 16 to the third side 20, as shown in
Optionally, attachment means 24 may be provided, in order to temporarily secure the step and support assembly 10 to a vertical support member 22, such as a 2 inch by 4 inch (hereinafter “2×4”) board or stud. Attachment means 24 may include screws that extend through holes in the first and/or third sides of the attachment member 12 and into the vertical board 22, or the attachment means 24 may be protruding teeth, spikes, bolts, nails, or any other suitable means for temporarily securing the attachment member 12 to the vertical board 22. If protruding teeth or spikes are used, they may be disposed perpendicularly or at an angle with respect to the planes of the first and/or third sides 16, 18 of the attachment member 12.
A series of step and support members 10 may be attached to vertical boards 22, in order to provide multiple steps, so that a user may climb upwardly on a house framing job, for instance, as shown in
In another embodiment, the step and support assembly 10 may be designed to be affixed to a stud or section of framing that is not vertically oriented, but rather, is oriented at an angle other than a vertical orientation. In this embodiment, the horizontal surface member extends angularly from the attachment member so that when the attachment member is affixed to a board in an angular orientation (45 degrees, for instance), then the step member is disposed in a generally horizontal orientation, as shown in Fig. __.
Optionally, the horizontal support surface 14 may be pivotally attached to the attachment member 12 to provide for an angular adjustment of the horizontal support surface 14, so that a user can attach the attachment member 12 to a board in an angular configuration (in other words, the board is not vertically oriented), and the user may then pivotally adjust the horizontal support surface 14 and secure it in a horizontal orientation. In this embodiment, as shown in
Optionally, the pin and holes may be threaded, so that the pin is screwed into the hole to secure the pin in place beneath the horizontal surface member for support. Other securing mechanisms or components may be used to temporarily support the horizontal surface member in a generally horizontal orientation, including bolts through the holes, snap-fit mechanisms, or other similar devices that are commonly used for such purposes and are well-known in the art.
The temporary step and support assembly 10 is preferably rigid, made from any suitable metal, high grade plastic or the like, and may be integrally formed or may be formed of multiple pieces and assembled. Although the function of the step and support assembly 10 has been described herein primarily as a step, it should be understood that the device 10 may also be used to support any desired item, including tools, tool bags, equipment, or any other item.
Although the present invention has been described in considerable detail with reference to certain preferred versions thereof, other versions are possible. Therefore, the spirit and scope of the appended claims should not be limited to the description of the preferred versions contained herein. All features disclosed in this specification may be replaced by alternative features serving the same, equivalent or similar purpose, unless expressly stated otherwise. Thus, unless expressly stated otherwise, each feature disclosed is one example only of a generic series of equivalent or similar features.
This application is a divisional application of U.S. patent application Ser. No. 16/124,248, filed on Sep. 7, 2018, which is hereby incorporated herein by reference, in its entirety.
