DETAILED DESCRIPTION

[0021] With reference to FIGS. 1 and 2, the assembly includes frame rail sides 1 and frame rail ends 2 connected between the frame rail sides 1 to define a framework. The side frame rails 1 are secured to the end frame rails 2 via cap screws 3 or the like. As shown, the end frame rails 2 may be provided with handles 15 making the assembly easier to pick up and move. Each of the frame rail ends 2 may be provided with holes (two shown) that allow for bolt mounting to other props or structures.

[0022] At least one mounting bar 8 is secured between the side frame rails 1. In an exemplary embodiment, as shown, each assembly may include five mounting bars 8. The mounting bars 8 are secured via shoulder bolts 4 or the like in the side frame rails 1. The mounting bars 8 may be provided with a central slot 50.

[0023] An articulation plate 11 is secured at one end of each of the mounting bars 8. Each articulation plate 11 includes connecting holes 12 for receiving connectors to secure the articulation plate 11 to the mounting bar 8 and an axle opening 32 for receiving the shoulder bolt 4. The articulation plates 11 also include a plurality of pin apertures 34 in an arcuate array at a bottom of the articulation plate 11. Locking pins 6 including pin spacers 5 are respectively engageable with one of the pin apertures 34 on each of the articulation plates 11.

[0024] FIG. 3A shows details of the articulation plate 11. FIG. 3B is a sectional view through the side frame rail 1 and through the locking pin 6. As described, the mounting bar 8 is pivotable on the shoulder screw 4, and the locking pin 6 locks an angular position of the mounting bar 8 via the apertures 34 in the articulation plate 11.

[0025] A setting plate 36 may be secured to an end of each of the mounting bars 8 opposite from the articulation plates 11. The setting plates 36 similarly include a plurality of pin apertures 38 therein. Setting pins 7 are respectively engageable with one of the pin apertures 38 on each of the setting plates 36. The setting pins 7 are configured such that they can be set to an open position without requiring a user to hold the pin.

[0026] Each of the mounting bars 8 is provided with a tube slot 40 defined by side rails 42 on opposite sides of a sliding surface 44. With particular reference to FIG. 5, at least a portion of the side rails 42 includes a shoulder 46 extending over the sliding surface 44 to define the tube slots 40. As shown, the shoulders 46 are spaced from an insert end of the mounting bars 8. The tube slots 40 may be in the form of machined ridges on either side of the mounting bars 8 that hold the tubes 14 and pyrotechnic devices in place.

[0027] Each of the tubes 14 may be provided with a mounting plate 48 at a bottom end that is sized to fit into the tube slots 40 of the mounting bars 8. The mounting plates 48 fit in the slot 40 between the shoulders 46 of the rails 42 and the sliding surface 44. That is, individual tubes 14 can slide onto the mounting bar 8 under the ridges on either side.

[0028] A tube stop 9 may be secured in the tube slot 40 via a thumbscrew 10 or the like to secure the tubes 14 in the tube slots 40.

[0029] FIGS. 4-6 show a process for securing six tubes 14 onto one of the mounting bars 8. As shown in FIG. 4, a first tube 14 is set into the slot of the mounting bar 8 and slid on the sliding surface 44 from an insert end toward an opposite end as shown in FIG. 5. Because the shoulder 46 is spaced from the insert end of the mounting bar 8, the mounting plate 48 can be readily inserted into the slot 40. The insert process is repeated for additional tubes 14. When the desired number of tubes 14 is secured on the mounting bar 8, the tube stop 9 is inserted into the slot 40 into engagement with the tubes 14 to secure the tubes in the tube slot. The thumbscrew 10 extends through the central slot 50 to engage a nut or other connector to lock the tube stop 9 in place. The locked tube stop secures the tubes 14 so that the tubes 14 will not move during discharge.

[0030] With reference to FIGS. 7 and 8, the locking pin 6 that engages the articulation plate 11 is positioned on one of the side frame rails 1, and the setting pin 7 that engages the setting plate 36 extends through the opposite side frame rail 1. The articulation plate 11 aligns with a machined hole in the side frame rail 1, and the locking pin 6 slides through the side frame rail 1 and the articulation plate 11. In some embodiments, each mounting bar 8 can be set at a maximum of nine different firing angles, although more or fewer angles could be accommodated.

[0031] The setting pin 7 allows the mounting bar angle to be set by just one user. After installing the tubes 14, the user engages the setting pin 7 on the rear frame rail 1 to set in an open position. Subsequently, the user uses one hand to release the locking pin 6 on the front frame rail 1 and the other hand to adjust the angle of the mounting bar 8 to a desired angle. Once the angle is set, the user engages the locking pin 6 and the setting pin 7, and the angle is locked in place. FIG. 9 shows an exemplary configuration with the mounting bar 8 set at a desired angle.

[0032] The assembly of the described embodiments facilitates mounting and setting of pyrotechnic devices using a plurality of selectively positionable mounting bars and a plurality of support tubes for each mounting bar that secure the pyrotechnic devices. The assembly is operable by a single user and can be easily transported and stored.

[0033] While the invention has been described in connection with what is presently considered to be the most practical and preferred embodiments, it is to be understood that the invention is not to be limited to the disclosed embodiments, but on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims.
