Technical Field

The invention relates to the sprinkler systems which detects the fire in indoor and outdoor areas and is used for fire extinguishing by spraying water.

The invention particularly relates to a sprinkler bracket with an upper clamp lock developed for the purpose of providing full locking after the assembly comprising of the bottom clamp and the upper clamp are locked to each other.

State of the Art

Today sprinkler systems are used to detect the fire indoor and outdoor areas and then provides fire extinguishing by spraying water. These systems are positioned on a suspended ceiling and formed by hanging the sprinkler part from the ceiling. In case of a fire, the system is activated and pumps water to the sprinklers and the water compressed to the system established with pipes advances to towards the sprinkler. In this manner, the sprinkler sprays the water within the environment and extinguishes the fire.

In the prior art, in case the sprinkler is required to be demounted, it shall be removed from the top. Since the sprinkler configuration is assembled on the narrow ceiling structures, the assembly and disassembly of the sprinkler takes much time and requires additional labor.

In the present state of the art, the sprinkler sleeve which fixes the sprinkler head is fixed to the profile. For this fixation process, the sleeve is inserted from the top portion to the profile. This process not only increase the labor processes but also extends the duration of the assembly and prevents the assembly to be realized in an efficient manner.

In the state of the art, since the handle which holds the lower and the upper clamp together is free at the pivot point, it is influenced by the environmental factors and thus it is loosened. The surfaces where the upper and the lower clamps contact to the sprinkler sleeve are not sufficient to retain the sleeve in a stable manner. This leads to slipping of the sleeve from the slot during water spraying and prevents performing an efficient spraying.

In the patent research made regarding the prior art, file No US20160279455A1 is encountered. In this application, the sprinkler sleeve is fixed to the profile with an integral apparatus. Therefore, this application can be referred as an example to the problems arises out of the insertion of the sleeve from the top. As a result of the researches made in the literature, various structures are encountered regarding the sprinkler system. One of them is the utility model with application No TR2007/05025. In the summary of the invention with classification category A62C 37/08, it is stated that; Our invention is related to a sprinkler hose system used in the indoor fire extinguishing installations having the duty of extinguishing the possible fires that may happen indoor areas, characterized by comprising; the metal end of the flexible hose which is connected to the main pipe via a main pipe connection end is fixed to the movable sliding part.

Detailed Description of an Embodiment of the Invention

Structure Principle;

The sprinkler bracket (1 ) consists of two main parts namely the lower clamp (10) and the upper clamp (20). The lower clamp (10) is a clamp group which enables the profile (P) and the sprinkler sleeve (S) to be fixed and remain together. The upper clamp (20) is the clamp group which is closed on the lower clamp (10) and locks the sprinkler sleeve (S) inside. Figure 1 is a perspective view of the lower clamp (10) and the upper clamp (20) in which they are coupled with each other and are in an open manner.

In the inner portion of the lower clamp (10), there is a profile housing (1 1 ) where the sprinkler profile (P) will pass through.

After the assembly of the lower clamp (10) and the upper clamp (20) to each other, a sleeve housing (50) is formed in the middle portion. The sleeve housing (50) is formed such that the clamp sleeve gaps (51 ) come face to face with each other which are formed inwardly in the middle portions of the lower clamp (10) and the upper clamp (20).

In order to firmly fix the sprinkler sleeve (S) into the sleeve housing (50) formed between the lower clamp (10) and the upper clamp (20), there are lower clamp holder nails (52) which are in the clamp sleeve gaps (51 ) of the lower clamp (10), have a concave structure facing outwards and are formed on both sides. The sprinkler sleeve (S) is compressed into the sleeve housing (50) by the lower clamp nails (52) and the upper clamp nails (53). With the same aim, the upper clamp holder nails (53) are formed on the upper clamp (20).

The connection of the lower clamp (10) and the upper clamp (20) with each other is performed by two elements from two different points. These elements are the locking bar (30) and the fastening element (40). The fastening element (40) fixes two parts to each other and rotating process is performed by taking this point as the center.

During the upper clamp (20) is fitted on the lower clamp (10), a locking bar housing (21 ) is formed on the end portion of the upper clamp (20) such that it fits in the locking bar (30).

The locking bar (30) is the element which enables the upper clamp (20) to be fixed after it is closed on the lower clamp (10). The handle (31 ) is formed by sloping the extension of the locking bar (30) outside the lower clamp (10). The handle (31 ) is the portion which helps rotating the locking bar (30) around its axis by 90 degrees in order to perform the locking process. Where the locking bar (30) is fixed to the lower clamp (10), a bar segment (32) is used.

The handle (31 ) is seen in detail in the figures. The structure of the handle (31 ) is such that after locking, it can lie down on the upper clamp (20). The position that it takes on the structure after locking is seen in Figure 3. The end portion of the handle (31 ) has a thinner structure compared to the other portions. This portion is the lock fitting portion (33), is the portion which is fitted into the handle lock (22) formed on the end portion on the side of fastening element (40) and on the upper clamp (20). Lock fitting portion (33) is seen more clearly in the figures.

Also, in all figures, the handle lock (22) formed on the upper clamp (20) is seen. The structure of the handle lock (22) has nails and is designed to prevent the unintentional protrusion of the lock fitting portion (33) which will be placed therein.

First, the profile (P) to be formed on the ceiling where the sprinkler hose will be attached, is fitted into the profile housing (1 1 ) located on the lower clamp (10). Subsequently, the lower clamp (10) and the upper clamp (20) are fixed to each other by the fastening element (40). A durable connection is performed by compressing the profile (P) with the lower clamp (10) via fixing. This fixation point allows for rotating the upper clamp (20) while this fixation points serves as a hinge.

The sprinkler sleeve (S) located on the end portion of the sprinkler hose is located in the sleeve housing (50) of the sprinkler bracket (1 ) which is in the position in Figure 2 in a perpendicular manner. After positioning, the upper clamp (20) rotates the fastening element (40) by taking the sleeve and is closed on the lower clamp (10). The sprinkler sleeve (S) when it is closed is compressed into the sleeve housing (50) by the lower clamp nails (52) and the upper clamp nails (53) which are clearly seen in Figures 1 and 3.

During the closing process, the locking bar housing (21 ) formed on the upper clamp (20) fits into the locking bar (30) and the connection takes place. The handle (31 ) which is the external portion of the locking bar (30) is perpendicular to the profile (P) by means of abutting to the handle border abutment (12). When the handle (31 ) is perpendicular to the profile (P), complete locking is not performed. The handle (31 ) is rotated in a parallel manner to the profile (P). Together with this rotation the handle (31 ) becomes parallel to the upper clamp (20) and the lock fitting section (33) formed on the handle (31 ) is fitted into the handle lock (22). Full locking of the handle (31 ) is realized by means of this fitting. When the system is required to be disassembled, the handle (31 ) is rotated by 90 degrees after it is released from the handle lock (22) and is brought perpendicular to the profile (P) by abutting on the border abutment (12) and the lock is opened. Subsequently, the upper clamp (20) is pulled upwardly in a manual manner and the locking bar housing (21 ) is released from the locking bar (30). The sprinkler sleeve (S) is removed from the sleeve housing (50) with this process.
