[Best Mode]

<37> The flush type sprinkler head in accordance with the present invention constituted as above will be now described minutely referring to the accompanying drawings.

<38> Fig. 1 is an external view of the flush type sprinkler head in accordance with the present invention. Fig. 2 is an exploded view of the flush type sprinkler head in accordance with the present invention. And Fig. 3 is a vertical sectional view showing the combination state of the flush type sprinkler head in accordance with the present invention.

<39> As it is shown, the flush type sprinkler head in accordance with the present invention comprises a body(10) connected to a piping(1), a water jet part of which the lower part forms into a housing part, a frame(30) which is joined with the body(10) and houses the said water jet part, a C- spring(40) which is installed in the lower part of the frame(30), a fuse box(50) which is joined to the lower part of the frame(30) and possesses the glass bulb fuse(58) and a bolt(60) which makes the glass bulb fuse(58) in the fuse box(50) ascend.

<40> The upper part of the body(10) is connected to the piping(1) and the middle part thereof forms into a flange(11) wherein a joining part(12) is formed. The inside diameter of the body(10) gets smaller as it goes from the upper part to the lower one so that it emits pressurized water.

<41> The water jet part(20) is housed in the frame(30). In ordinary times, it is joined in the state of being inserted into the flange(11) of the body(10). On the occasion of a fire, it is descended by the pressure of extinguishing water and emits extinguishing water. The upper part of the water jet part(20) forms into a hanging protrusion(21) and the top of the lower part thereof forms into a deflector(22) with which the emitted extinguishing water collides on the occasion of a fire. The lower part of the water jet part(20), that is, the external circumference of the deflector(22) forms into many flushing passageways(25) so that extinguishing water flushes all around and extinguishes a fire. The deflector(22) of the water jet part(20) and the lower part of the body(lθ) are sealed with an O-ring(23). Additionally, the lower part of the water jet part(20) forms into a housing part(24).

<42> The upper part of the frame(30) is joined in the flange(ll) of the body(10) and the lower part of the frame(30) forms into a hanging bump(31). On the occasion of a fire the water jet part(20) descends and the hanging protrusion(21) which is formed at the upper part of the water jet part(20) is hung on the hanging bump(31), which prevents the water jet part(20) from being separated from the frame(30) and falling. A groove for hanging a spring(32) is formed in the hanging bump(31). The C-spring(40) is hung on the groove for hanging a spring(32) and thus joined with the frame(30).

<43> The spring(40) forms into C-ring. As the spring(40) widens, the fuse box(50) is hung on the groove for hanging a spring which is formed in the hanging bump(31) and connected to the frame(30). As it narrows, the fuse box(50) is separated from the frame(30). If the C-spring is used like this, the sprinkler head is lower than that of the conventional sprinkler which used a compressed spring and thus the protruded length on the ceiling gets lower. Accordingly, it enhances the interior view due to the beautiful external appearance of the ceiling.

<44> An opening part(51) is formed at the upper part of the fuse box(50). At the side of the upper part of the fuse box(50), a groove for connecting a spring(53) is formed. On the groove for connecting a spring(53), the spring(40) is joined and pierced holes(52) is formed symmetrically. And ball bearings(54) are inserted into the pierced holes(52). The opening part(51) is joined with a supporting frame(57) of which the upper part is inserted into the housing part(24) of the water jet part(20) and the circumference surface of the lower part forms into a siant(55) so that the supporting frame(57) is descended by the ball bearings(54) receiving the tightening power of the spring(40). A hole for screwing a bolt(56) is formed in the middle of the lower part of the fuse box(50). The fuse box(50) houses the glass bulb fuse(58) which is installed between the bottom of the supporting frame(57) and the hole for screwing a bolt(56).

<45> The spring(40) is joined on the groove for connecting a spring(53). The pierced holes(52) are formed symmetrically on the groove for connecting a spring(53). And the ball bearings(54) are inserted into the pierced holes(52). The ball bearings(54) which are inserted into the pierced holes(52) are moved inside by the tightening power of the spring(40).

<46> The the supporting frame(57) is formed like a circular corn of which the lower part has the larger diameter. And the circumference surface of the lower part of the supporting frame(57) forms into a slant(55). The upper part of the supporting frame(57) forms into a platform, is inserted into the housing part(24) of the water jet part(20) and supports the water jet part(20). If the supporting frame ascends and is joined, the ball bearings(54) which touches the slant(55) of the supporting frame(57) are joined in a state of receiving elasticity as the spring(40) which touches the ball bearings(54) widens. On the contrary, when it is separated, the spring(40) narrows and pushes the ball bearings(54) inside. Thus the ball bearings(54) moves to the upper part of the supporting frame(57) along the slant(55) and makes the supporting frame(57) descends. A hole for screwing a bolt(56) is formed in the middle of the lower part of the fuse box(50) and a bolt(60) is joined to the hole for screwing a bolt(56).

<47> The upper part of the glass bulb fuse(58) is housed by the lower part of the supporting frame(57). The glass bulb fuse(58) is made by sealing the thermal expansion liquid like glycerin or an ether compound in the special glass. If the ambient temperature is raised by the heat on the occasion of a fire, the liquid in the glass bulb fuse(58) expands and destroys the glass bulb fuse(58).

<48> It is desirable to form many pierced grooves(59) on the circumference surface of the fuse box(50) so that the glass bulb fuse(58) senses the heat and breaks easily.

<49> It is desirable to form each housing fuse part(57a,61) on the top of the bolt(60) and in the lower part of the supporting frame(57) so that the glass bulb fuse(58) is installed easily. The glass bulb fuse(58) is positioned between the bolt(60) and the supporting frame(57). Like this, the glass bulb fuse is joined to compress the supporting frame(57) upward, which makes a strong combination. Thus it provides a merit that a fault like a leakage of the sprinkler head, etc doesn't happen. If the bolt(60) is joined to a hole for screwing a bolt(56) supporting the glass bulb fuse(58), the glass bulb fuse(58) is joined moving the supporting frame(57) upward and the slant(55) of the supporting frame(57) moves upward making the ball bearings(54) move out. Thus the ball bearings(54) makes the spring(40) widen and inserted into the groove for hanging a spring(32) which is formed in the hanging bump(31) of the frame(30). Consequently, the fuse box(50) is joined to the frame(30).

<50> Fig. 4 and Fig. 5 are vertical sectional views showing the function state of the sprinkler.

<51> As it is shown, if the glass bulb fuse(58) is destroyed by the heat, the spring(40) narrows and moves along the slant(55) of the supporting frame(57), the supporting frame(57) descends and the spring(40) is separated from the groove for hanging a spring(32). Thus the fuse box(50) is separated from the frame(30). (Referring to Fig. 4) At the same time with that, the water jet part(20) descends and the hanging protrusion(21) which is formed at the upper part of the water jet part(20) is hung on the hanging bump(31) which is formed at the lower part of the frame(30). And then the fire extinguishing water puts out a fire colliding with the deflector(22) and being emitted through the many flushing passageways(25). (Referring to Fig. <52> 9
