In yet another embodiment of the present invention the mounting bracket assembly may be defined as having a mounting bracket positioned on the latitudinal support unit between the pair of longitudinal support units for positioning and supporting the sprinkler reducer. The mounting bracket may have a pair of sidewalls extending from a base wall to form a mounting channel along a entire length of the base wall. The mounting bracket may further have a mouth such that the latitudinal support unit may be positioned between the sidewalls in the mounting channel against the base wall. Each sidewall includes an opening along an end of the sidewall opposite the base wall, and the openings having a predetermined shape to accommodate a portion of a profile defined by the sprinkler reducer. The mounting bracket assembly further includes a locking unit being pivotally secured to at an end to both sidewalls. The locking unit includes a pair of side members extending downwardly from a base member, each side member further includes an opening along an end of the side members opposite the base member. The openings have a predetermined shape to accommodate a portion of the profile defined by the sprinkler reducer. The base member includes a slot positioned such that an opening to the slot is positioned at an edge of the base member between the two side members. The mounting bracket assembly further includes a locking member pivotally mounted to the two sidewalls on the mounting bracket and having an elongated shaft extending upwardly for receipt into the slot on the base member of the locking unit. A locking nut is positioned on the elongated shaft such that when the locking unit is in a closed positioned about the mounting bracket the openings in the sidewalls and in the side members align to accommodate the sprinkler reducer and the elongated shaft may be pivoted to be received into the slot thereby allowing the locking nut to be tightened to secure the locking unit to the mounting bracket and secure a sprinkler reducer positioned therebetween.

 DESCRIPTION OF THE PREFERRED EMBODIMENTS

While the invention is susceptible to embodiments in many different forms, there are shown in the drawings and will be described herein, in detail, the preferred embodiments of the present invention. It should be understood, however, that the present disclosure is to be considered an exemplification of the principles of the invention and is not intended to limit the spirit or scope of the invention and/or claims of the embodiments illustrated.

Referring now to FIG. 1, a sprinkler mounting assembly 100 according to a first embodiment of the present invention is shown. The sprinkler mounting assembly 100 includes a mounting bracket 110 having a locking unit 120, a latitudinal support bar 130 to which the mounting bracket 110 is movably coupled, and a pair of longitudinal support units 140 which are coupled to opposite ends of the support bar 130. As shown in FIG. 2, the mounting bracket 110 may slide or move along the length of the latitudinal support bar 130, such that the placement of the sprinkler system is easily adjustable during assembly.

Referring now also to FIGS. 3A-3E, the mounting bracket 110 includes two sidewalls 150 separated by a base wall 152 having a predetermined width such that the two sidewalls 150 are spaced apart from one another by a predetermined distance. The mounting bracket 110 has a mouth 154 at an end opposite the base wall 152. The two sidewalls 150 also include a through hole 156 and a flange 158. The mounting bracket 110 further has a mounting channel 160 formed along the length of base wall 152 and between the two sidewalls 150 to allow receipt of the latitudinal support bar 130. This permits the latitudinal support bar 130 to be positioned against and be supported by the entire base wall 152, which may be an improved manner of support than the prior art. The two sidewalls 150 further include a U-shaped opening 162 positioned in the sidewalls 150 such that a remaining portion 164 is present on either side of the opening 162. The U-shaped opening 162 has a predetermined curvature to accommodate the profile of a sprinkler reducer 146. The U-shaped opening 162 may further be defined as having a curved end 163 that mates to two longitudinal ends 165. As known in the art, the sprinkler reducer 146 may be attached at one end to a flexible tubing 142, which is further secured to a water supply pipe 144.

The mounting bracket 110 further includes a locking unit 120 that may be preferably rigidly constructed, such as, but not limited to, a steel wire bent to form the shape as described herein. The locking unit 120 includes a pair of ends 166 to pass through the through holes 156 on each sidewall 150. The locking unit 120 bends from the pair of ends 166 to form first leg portions 168 that traverse the length of U-shaped opening 162 running along one of the remaining portions 164. Extending beyond the two sidewalls 150, the first leg portions 168 then bend to from latitudinal portions 170 that traverse the U-shaped opening 162. At the opposite side of the U-shaped opening 162, the locking unit 120 bends to form second leg portions 172, which run down the opposite remaining portions 164 towards the flanges 158. The locking unit 120 then forms mating portions 174 that can be positioned against the flanges 158 (to lock the sprinkler reducer 146 as shown in FIGS. 1 and 2 in place). From the mating portions 174 the locking unit 120 bends to form a handle portion 176 that connects the two mating portions 174 on either sides of the locking unit 120.

During operating, the sprinkler reducer 146 is positioned in the U-shaped opening 162 and the locking unit 120 is moved such that the latitudinal portions 170 are positioned against the sprinkler reducer 146. The mating portions 174 are locked against the flanges 158, thereby locking the sprinkler reducer 146 into position. The sprinkler reducer 146 is thus supported by the latitudinal portions 170 and the U-shaped opening 162. To remove the sprinkler reducer 146, the mating portions 174 are unlocked from the flanges 158 allowing the locking unit to pivot away from the sprinkler reducer 146 about its ends 166 and the through holes 156.

Referring now to FIGS. 4A-4C, there is shown one of the pairs of longitudinal support units 140, which is shown in FIGS. 1 and 2 and used to connected the latitudinal support bar 130 to connect the sprinkler system to a ceiling frame section 50 or more particularly to a frame support member 55. As is well known in the industry, the frame support members 55 have a T-shaped portion 57 near its top portion that is used to connect to the longitudinal support units 140, as discussed in greater detail below.

Each longitudinal support unit 140 includes two side members 200 that extend downwardly from a top member 202. Each side member 200 includes a support bar window 204 for receipt of an end of the latitudinal support bar 130. A sill member 206 is positioned below each support bar window 204 extending inwardly towards the opposite side member 200.

The sill member 206 lends support to or helps seat the latitudinal support bar 130 that is inserted through the support bar window 204. The top member 202 includes a threaded aperture 208 to receive a tightening element 210 (shown in FIG. 1), such as a screw, that can be used to lock the longitudinal support unit 140 in a substantially rigid position against the latitudinal support bar 130.

A lower portion 212 of side member 200 moves inwardly at a first section 220 towards each other and then turns downwardly to ends 214 of each of the side members 200. Positioned above the first sections 220 on both side members 200 are flanges 222. The area between the flanges 222 and the first sections 220 creates a latitudinal support region 215 along the first sections 220 and the side member 200 for receiving the top of the T-shaped portion 57.

The ends 214 of the side members 200 may have a slight outwardly flared region 216 to help accommodate the top of the T-shaped portion 57 of the frame support member 55. The ends 214 further include extending side sections 218 that make the ends 214 wider then the widths of the side members. This serves as a means to help grab into the top of the T-shaped portion 57 when the sprinkler system is in use and is exhibiting a large amount of back pressure. This also serves as a means to prevent rocking of the mounting apparatus on the frame support members 55.

Positioned through the side members 200 near the positions of the flanges 222 are threaded openings 224 for receiving a tightening bolt 226 (shown in FIGS. 1 and 2). When the tightening bolt 226 is tightened, the side members 200 move towards each other causing the ends 214 to pinch against sides of the frame support member 55 and securing the T-shaped portion 57 in the latitudinal support region 215. Conversely, when the tightening bolt 226 is loosened, the ends 214 release and the longitudinal support unit 140 may be removed from the frame support member 55.

Referring now also to FIG. 4D, there is shown a longitudinal support unit 140 that includes a secondary threaded opening 224a positioned above the primary threaded opening 224. Either opening 224 or 224a could be used to secure the longitudinal support unit 140 to the side of a ceiling structure or wall. In addition, the longitudinal support unit 140 illustrated in FIGS. 4A-4C could also be secured to a wall of other mountable structure by using a mounting member through the threaded opening 224. In some instances when a ceiling frame section is not used or provided, the mounting structure 100 can still be secured in a building to a wall, I-beam, or other mountable structures.

Referring now also to FIGS. 5A-5G, there is shown a second type of mounting bracket 300 in accordance with another embodiment of the present invention. The mounting bracket 300 includes two sidewalls 302 separated by a base wall 304 having a predetermined width such that the two sidewalls 302 are spaced apart from one another by a predetermined distance. The mounting bracket 300 has a mouth 306 at an end opposite the base wall 304. The mounting bracket 300 further has a mounting channel 308 formed along the length of base wall 304 and between the two sidewalls 302 to allow receipt of the latitudinal support bar 130. This permits the latitudinal support bar 130 to be positioned against and be supported by the entire base wall 304, which may be an improved manner of support than the prior art. The two sidewalls 302 further include a U-shaped opening 310 positioned in the sidewalls 302 such that a remaining side portion 312 is present on either side of the opening 310. The U-shaped opening 310 has a predetermined curvature to accommodate the profile of a sprinkler reducer 146. The U-shaped opening 310 may further be defined as having a curved end region 314 that merges into to two longitudinal ends 316.

The mounting bracket 300 further includes a locking unit 320 that is pivotally secured to at pivot points 322 on both sidewalls 302, and preferably located at one of the remaining side portions 312. The locking unit 320 includes a pair of side members 324 that extend downwardly from a base member 326. The base member 326 may also have a width W2 that is greater then the width W1 defined by the base wall 304 on the mounting bracket 300. Alternatively, the side members 324 may extend at an angle A1 from the base member 326. In either instance, the side members 324 would have an interior section 328 that would overlap the exterior section 341 on the sidewalls 302. The side members 324 further include a U-shaped opening 350 positioned in the side members 324 such that remaining side portions 352 are present on either side of the openings 350. The U-shaped opening 350 has a predetermined curvature to accommodate the profile of a sprinkler reducer 146. The U-shaped opening 350 may further be defined as having a curved end region 354 that merges into to two longitudinal ends 356.

The base member 326 further includes a slot 330 positioned such that an opening 332 to the slot is positioned at an edge 334 of the base member 326. The locking unit 320 further includes a locking member 336 defined has having an elongated shaft 338 pivotally connected at one end 340 to the sidewalls 302 of the mounting bracket 300. The pivotal connection includes a transverse section 342 pivotally connected at points 344 to the interior region 346 of the sidewalls 302. The elongated shaft 338 is threaded to receive a locking nut 348.

During operating, the sprinkler reducer 146 is positioned in the U-shaped opening 310 and the locking unit 320 is pivoted such that its U-shaped opening 350 is also positioned against the sprinkler reducer 146. The elongated shaft 338 is then pivoted such that it is received in the slot 330 and the locking nut 348 is turned to tightly secure the locking unit 320 with the mounting bracket 300. The sprinkler reducer 146 is thus supported and secured within the two U-shaped openings defined by the locking unit 320 and the mounting bracket 300. To remove the sprinkler reducer 146, the locking nut 348 is loosened such that the elongated shaft 338 is able to pivot out of the slot and the locking unit 320 may pivot into an opened positioned away from the sprinkler reducer 146.

From the foregoing and as mentioned above, it will be observed that numerous variations and modifications may be effected without departing from the spirit and scope of the novel concept of the invention. It is to be understood that no limitation with respect to the specific methods and apparatus illustrated herein is intended or should be inferred. It is, of course, intended to cover by the appended claims all such modifications as fall within the scope of the claims.
