DETAILED DESCRIPTION
A bracket system for mounting an electrical panel onto a handrail will now be described with reference to FIGS. 1 through 8.
Referring to FIG. 7, an electrical panel 12 has an upper mounting bracket 14 and a lower mounting bracket 16. Referring to FIG. 8, there is an upper handrail bracket 18 attached to upper mounting bracket 14 and a lower handrail bracket 20 attached to lower mounting bracket 16. Upper and lower mounting brackets 14 and 16 may be already attached to electrical panel 12, or they may be attached at the time of installation. Furthermore, upper handrail bracket 18 may be permanently attached to, or integrally formed with, upper mounting bracket 14. Lower handrail bracket 20 may be permanently attached to lower mounting bracket 16 by a vertically adjustable connection 34, as some movement is required by lower handrail bracket 20 relative to electrical panel 12 during installation to properly position lower handrail bracket 20. Referring to FIG. 6, in a preferred embodiment, connection 34 is a sliding connection formed by providing lower mounting bracket 16 with a vertical slot 17 that allows a pin connection 19 secured to lower handrail bracket 20 to move vertically relative to electrical panel 12. Other sliding connections 34 will be apparent to those skilled in the art. This allows the installer to lift lower handrail bracket 20, position electrical panel 12, and let bracket 20 fall into place.
Referring to FIG. 1, upper handrail bracket 18 has a first portion 22 having a U-shaped cross-section 24 and a second portion 26 having an attachment 28 for attaching to upper mounting bracket 14 of electrical panel 12 (as shown in FIG. 7). As shown, attachment 28 is a series of apertures. First portion 22 is connected to second portion 26 by a pivotal connection 30 that allows first and second portions 22 and 26 to pivot between an angled position shown in FIG. 2 and a relatively flat position shown in FIG. 3. The position shown in FIG. 3 is intended to simplify and permit installation on a handrail, while the position shown in FIG. 2 is the installed position that helps secure upper handrail bracket 18, and therefore electrical panel 12, on a handrail.
Referring to FIGS. 4 and 5, lower handrail bracket 20 preferably has a U-shaped, receiving body 32 with an attachment 34 for attaching to lower mounting bracket 16 of electrical panel 12 (as shown in FIG. 7. As shown, attachment 34 includes a pin connection 19 that engages slot 17, such that the vertical position of lower handrail bracket 20 may be adjusted.
Referring to FIG. 8, upper and lower handrail brackets 18 and 20 are used to install electrical panel 12 on a handrail, which has an upper handrail 36 and a lower handrail support 38. Upper handrail 36 is shown as an angle iron, and lower handrail support 38 is shown as a flat bar, and the discussion below will be given in that context. However, it will be understood that the attachment portions of upper handrail bracket 18 and lower handrail bracket 20 may be designed to accommodate different sizes and shapes. For example, upper handrail 36 may be a square tubing, which requires upper handrail bracket 18 to have a wider U-shaped cross-section 24. It will be understood that, in order to properly mount upper handrail bracket 18 in this manner, upper handrail 36 must have a cross-section with upper and lower opposed, parallel faces, that allows first portion 22 to engage and hold handrail 36. The same restriction is not placed on lower handrail bracket 20.
Referring to FIG. 7, upper handrail bracket 18 is attached to upper mounting bracket 14 by using pin connections through attachment 28. Lower handrail bracket 20 may be loosely attached to lower mounting bracket 16 by a pin connection through attachment 34 and slot 17. Upper handrail bracket 18 is extended to a substantially horizontal position, such that electrical panel 12 is also substantially horizontal, which allows U-shaped portion to engage upper handrail 36. As can be seen, first portion 22 is substantially the same length as the width of upper handrail 36. Referring to FIG. 8, as second portion 26 of upper handrail bracket 18 is pivoted about pivotal connection 30 to lower electrical panel 12 into the vertical position, upper handrail 36 is secured within U-shaped portion 24 by second portion 26. Once upper handrail bracket 18 is installed, lower handrail bracket 20 is installed by lifting it along slot 17 above lower handrail support 38, and lowering it such that lower handrail support 38 enters receiving body 32. The pin connection through attachment 34 and slot 17 can then be tightened to secure lower handrail bracket 20 in place, which also prevents any movement about pivotal connection 30, which is necessary to dislodge electrical panel 12 from the handrail.
It will be apparent that other types of lower handrail brackets 20 may be used, such as a clamp that is positioned vertically first, then clamped onto lower handrail support 38, such as a structure similar to a scaffolding clamp.
In this patent document, the word “comprising” is used in its non-limiting sense to mean that items following the word are included, but items not specifically mentioned are not excluded. A reference to an element by the indefinite article “a” does not exclude the possibility that more than one of the element is present, unless the context clearly requires that there be one and only one of the elements.
The following claims are to be understood to include what is specifically illustrated and described above, what is conceptually equivalent, and what can be obviously substituted. Those skilled in the art will appreciate that various adaptations and modifications of the described embodiments can be configured without departing from the scope of the claims. The illustrated embodiments have been set forth only as examples and should not be taken as limiting the invention. It is to be understood that, within the scope of the following claims, the invention may be practiced other than as specifically illustrated and described.
