Abstract
A cart that uniformly transverses floor decking that has sequential peaks and valleys. The cart comprises a wheel assembly having an array of wheels forming rows and columns of wheels positioned under the cart wherein at any given instant of time a number of the wheels of the rows and columns contact peaks of the floor decking and while other wheels extend over and free from contacting the valleys such that the cart uniformly traverses the floor decking.
Claims19
A cart for uniformly traversing a construction floor decking that has sequential peaks and valleys prior to cement being poured on the construction floor decking, the cart comprising:
- a housing having:
- a rigid bottom;
- a top;
- and
- a side connecting the rigid bottom and the top;
- and
- a wheel assembly connected to the rigid bottom of the cart, the wheel assembly having an array of multidirectional wheels having the same size and forming a predetermined pattern of wheels positioned under the cart, the array of multidirectional wheels forming rows and columns of multidirectional wheels in a configuration such that adjacent rows of wheels are laterally offset from each other from one to three inches and adjacent columns of wheels are longitudinally offset from each other from one to three inches and centerlines of the rows are positioned seven to eight inches from each other and wherein centerlines of the columns are positioned seven to eight inches from each other, wherein at any instant of time a number of the multidirectional wheels are configured to contact a plurality of peaks of the construction floor decking while other multidirectional wheels extend over and remain free from entering into the valleys, the peaks having widths from three inches to six inches while the corresponding valleys having widths from two inches to eight inches such that the cart evenly traverses the construction floor decking.

A cart for welding studs while traversing a construction floor decking that has sequential peaks and valleys, the cart comprising:
- a housing having a base, a top and a side connecting the base and the top;
- a stud feed assembly connected to the housing, the stud feed assembly having a stud loader and a stud catcher, the stud loader having a chute connected to the housing to feed a plurality of studs to the stud catcher, the chute includes an entry end and an exit end, the entry end being positioned near the top of the housing and the exit end being positioned near the base of the housing and extending outward from the side of the housing, the entry end having an opening configured to accept and align the plurality of studs in an end-to-end relationship, the exit end having an angled surface configured to guide at least one stud of the plurality of studs out of the chute and toward the catcher, the stud catcher being suspendably connected to near the base of the housing, the stud catcher having a receptacle positioned below the exit end, the receptacle being shaped to receive the stud from the plurality of studs such that the receptacle vertically aligns the received stud with respect to the housing;
- an arm assembly movably connected to the housing, the arm assembly having a linkage member extending beyond the side of the housing and an extension member vertically connected to the linkage member, the linkage member being configured to rotate the extension member about the housing;
- and
- a stud gun axially connected to the extension member wherein a worker, while in a standing position, moves the extension member to position the stud gun to capture the stud that is vertically aligned within the receptacle of the stud catcher and the worker then moves the captured stud and stud gun to a welding location where the worker activates the stud gun to stud weld the stud while the worker remains in the standing position.

- and
- an analyzer operatively connected to the stud gun wherein the analyzer comprises a time circuit which measures, in real time, time of the activated stud gun;
- a current circuit that measures, in real time, current applied to the stud gun as the stud gun stud welds the stud;
- a lift circuit which measures, in real time, the lift displacement and a plunge circuit which measures, in real time, the plunge displacement such that the real time measurements of the time circuit, the current circuit, the lift circuit and plunge circuit are measured at the location of the welded stud.
