COLUMN ATTACHMENT
A column attachment having an abutment, a platform, a tension member, and a securing element that are used to provide a stable support for a device. The tension member secures the platform to the abutment. The securing portion is able to slide along a slot defined in the platform. The securing portion is able to attach to devices, like total stations, and secure them to the platform.
The invention relates to portable stand that needs not touch the ground. The portable stand can serve as a stable platform for devices used in construction.
BACKGROUND OF THE INVENTIONDuring construction, constant measurements must be taken to insure that the structure is adhering to the design being built. Many times a scanner and/or total stations are used to take these measurements. A total station is an electronic/optical instrument used in modern surveying. The total station is an electronic theodolite (transit) integrated with an electronic distance meter (EDM) to read distances from the instrument to a particular point.
The total station, and most all other devices, need to be stable in order to make precise measurements. However, in many situations, the surface near where the device must be set does not allow a tripod to provide a stable surface. Other times it is just inconvenient or very difficult to use a tripod due to the state of the surface. In some cases, metal or wood decking is set as a form before the concrete floors are poured which is not a stable footing for a tripod.
Many aspects of the embodiments can be better understood with references to the following drawings. The components in the drawings are not necessarily drawn to scale, the emphasis instead being placed upon clearly illustrating the principles of the embodiments. Moreover, in the drawings, like reference numerals designate corresponding parts throughout the several views.

The platform 1 defines a slot 12 that allows for adjusting the location of the device along the platform 1. The slot 12 can be in communication with the platform through hole 13. The platform through hole 13 can have a thread that corresponds to the securing portion 32. In other embodiments, the through hole 13 need not be threaded. The through hole 13 allows the securing element 3 to be removed. In some embodiments, the platform 1 does not have a through hole 13, and the securing element 3 is retained by and able to move along the slot 12. The platform 1 can also define a curved slot 14. The curved slot 14 allows the platform to move relative to the periphery tension member 5 so as to rotate the platform 1. The platform can also define an aperture through which the center tension member 4 extends to engage the abutment 6.
The lower support element 10 comprises a base 101 and one or more arms 102 extending from the base 101. The lower support element 10 is secured to the abutment 6 by a lower tightening member 11. The lower tightening member 11 is able to increase the pressure between the lower support element 10 and the abutment 6. Thus the relative movement between the abutment 6 and the lower support element 10 is limited. Each arm 102 can have one or more braces 2 attached thereto. In the embodiment shown in
The lower tightening member 11 can have a threaded portion 111 that corresponds to a threaded element located on the abutment 6. The lower tightening member 11 also has a handle portion 112. The handle portion 112 can be an adjustable clamping lever or a knob.
The platform 1 is connected to one or more braces 2. As seen in

The one or more strap accepting sections 7 are located on the abutment 6. The strap accepting sections 7 can serve as a guide for a strap 8. In some embodiments, there is a strap accepting section 7 on each of the projections 61 and on the center portion 62. The size of the strap accepting sections 7 can be changed according to need. In some embodiments, there are multiple strap accepting sections 7 of varying sizes on one of the projections 61, both of the projections 61, and/or the center portion 62. The strap accepting sections 7 can form a full enclosure, so that the strap is threaded through, or define a gap that will enable the strap 8 to be inserted therein (not shown). In some embodiments, the strap accepting section(s) 7 is merely an indentation in the abutment 6 (not shown).
The center tension member 4 and the periphery tension member 5 can comprise an adjustable clamping lever with a threaded member that engages the abutment 6. In other embodiments, the center tension member 4 and the periphery tension member 5 can comprise a knob with a threaded member. When the user tightens the center tension member 4 and/or the periphery tension member 5, it increases the pressure between the platform 1 and the upper portion 63. Some embodiments lack the center tension member 4 and there is an attachment between the platform 1 and the abutment 6 that allows for rotational movement. Other embodiments lack the periphery tension member 5.
The strap tensioning member 9 is used to tighten the strap 8 and secure the abutment 6 member to a column. In some embodiments, the strap tensioning member 9 is an endless loop ratchet. In other embodiments different types of tensioning devices can be used to secure the abutment 6 to the stable object such as a cambuckle or gunwale strap.
It is understood that the components can be comprise varying materials. These materials include, but are not limited to, steel, aluminum, other metals, plastics, composites, laminates, nylon, and combinations thereof.
During use a user will secure the abutment 6 to a column, post or other stable object. This can be done using the strap 8. The strap 8 is situated in or on the strap accepting sections 7 wrapped around the column, post or other stable object, and tightened until there is sufficient tension to secure the abutment 6 to the a column, post or other stable object. The tightening of the strap 8 can be achieved by the use of the strap tensioning member 9. If the object is a square column, the two projections 61 will abut surfaces of the square column, as shown in
