Background Technology

[0002] Figure 1 is a structural diagram of a typical sprinkler head.

[0003] Referring to this drawing, the sprinkler head (10) is connected to the fire extinguishing water supply line (20) through the connection part (14).

[0004] A pair of guard frames (11) are installed in the joint (14). A reflector plate (13) that sprays fire extinguishing water in all directions is fixedly mounted at the bottom of the guard frame (11). A glass bulb (12), which is a heat-sensing part, is installed between the outlet of the fire extinguishing water supply line (20) and the reflector plate (13).

[0005] When a fire occurs, the glass bulb (12) bursts and extinguishing water is discharged from the extinguishing water supply line (20) and sprayed through the reflector (13).

[0006] As such, the glass bulb (12), which is the heat-sensing part, must be protected. To this end, there are examples where a sprinkler head protective mesh in the form of Fig. 2 has recently been applied. In addition, a sprinkler head protective mesh in the form of Fig. 3 has also recently been used. For reference, the sprinkler head protective mesh of Fig. 2 is a drawing disclosed in the document of application number 10-2010-0041151, and the sprinkler head protective mesh of Fig. 3 is a drawing disclosed in the document of application number 20-2008-0013667.

[0007] However, in the case of a sprinkler head protection mesh according to the prior art including FIGS. 2 and FIGS. 3, there are the following problems.

[0008] First, there is a problem in that the upward bolting method makes the work inconvenient when working on post-construction, and it is inevitably very cumbersome to work in high and narrow spaces.

[0009] Second, there is a problem in that it must be used according to specifications that are not common, such as 15A, 20A, etc.

[0010] Third, since the fastening part of the head consists of a combination of scrap metal, the fastening process is not easy, and there is a problem in that a tight seal is particularly impossible.

[0011] Fourth, due to structural limitations, there is a problem in that modification work is not easy if there are modifications after installation. Prior art literature

[0021] The advantages and features of the present invention and the methods for achieving them will become clear by referring to the embodiments described below in detail together with the accompanying drawings.

[0022] However, the present invention is not limited to the embodiments disclosed below but will be implemented in various different forms.

[0023] In this specification, the embodiments are provided to make the disclosure of the invention complete and to fully inform those skilled in the art of the scope of the invention. The invention is defined only by the scope of the claims.

[0024] Accordingly, in some embodiments, well-known components, well-known operations, and well-known techniques are not specifically described to avoid the invention being interpreted ambiguously.

[0025] Throughout the specification, the same reference numerals refer to the same components. Furthermore, the terms used (mentioned) in this specification are for describing the embodiments and are not intended to limit the invention.

[0026] In this specification, the singular form includes the plural form unless specifically stated otherwise in the text. Additionally, components and actions (operations) referred to as 'comprising (or having)' do not exclude the presence or addition of one or more other components and actions.

[0027] Unless otherwise defined, all terms used in this specification (including technical and scientific terms) may be used in a meaning that is commonly understood by those skilled in the art to which the present invention belongs.

[0028] Furthermore, terms defined in commonly used dictionaries are not interpreted ideally or excessively unless otherwise defined.

[0029] Hereinafter, preferred embodiments of the present invention will be described with reference to the attached drawings.

[0030] FIG. 4 is a front view of a sprinkler head protection mesh according to a first embodiment of the present invention, FIG. 5 is a plan view of FIG. 3, FIG. 6 is a side view of FIG. 4, FIG. 7 is an operational side view of FIG. 6, and FIG. 8 is a view of the usage state of FIG. 6.

[0031] Referring to these drawings, the sprinkler head protection mesh (100) according to the present embodiment is fastened in a clamping manner using a torsion spring (140) with strong tension, so it can be easily installed without using various tools or parts including bolts. Additionally, since an elastic body (114, 124) is applied to the part that engages with the sprinkler head (10), it can be tightly secured and easily fixed. Furthermore, it can be applied as a common size without the need for cumbersome distinction by size, and even if there are modifications after installation, it allows for easy modification work.

[0032] The sprinkler head protection mesh (100) according to the present embodiment, which can provide such significant effects, may include first and second protection mesh units (110, 120), a hinge module (130), a torsion spring (140, torsion spring), and a latch (150).

[0033] The first protective mesh unit (110) is a structure that is positioned on one side of the sprinkler head (10) as shown in FIG. 7 and protects one side of the sprinkler head (10) at that location. When water is sprayed from the sprinkler head (10) positioned inside, the first protective mesh unit (110) is formed as a mesh body with holes generally so that the sprayed water can easily escape to the outside.

[0034] The second protective mesh unit (120) is a structure that protects the other side of the sprinkler head (10) at that location, similar to the first protective mesh unit (110) as shown in FIG. 7. When water is sprayed from the sprinkler head (10) placed inside, the second protective mesh unit (120) is also formed as a mesh body with holes throughout so that the sprayed water can easily escape to the outside.

[0035] This second protective mesh unit (120) has the same shape as the first protective mesh unit (110) but is arranged symmetrically with respect to the first protective mesh unit (110). Since the first and second protective mesh units (110, 120) have the same shape, manufacturing and maintenance are easy. In addition, the sprinkler head protective mesh (100) according to the present embodiment can have the same shape regardless of which side it is viewed from, thereby enhancing the aesthetic appeal of the appearance.

[0036] The first protective mesh unit (110) and the second protective mesh unit (120) described above are provided with first and second head supports (113, 123) that support the sprinkler head (10).

[0037] Additionally, first and second elastic bodies (114, 124) are provided on the inner surfaces of the first and second head supports (113, 123) to maintain close contact with the sprinkler head (10). The first and second elastic bodies (114, 124) are a type of rubber or silicone pad that enables tight contact with the sprinkler head (10) and allows for easy fixation. Furthermore, they provide the flexibility to be applied as a universal size without the need for cumbersome differentiation by size.

[0038] The hinge module (130) is a part that forms the axis of rotation of the first protective net unit (110) and the second protective net unit (120). As shown in FIGS. 6 and 7, the first protective net unit (110) and the second protective net unit (120) can be opened or closed with the hinge module (130) as an axis.

[0039] A torsion spring (140) is provided in the hinge module (130) and elastically biases the first protective mesh unit (110) and the second protective mesh unit (120) in a closing direction as they come into contact with each other. That is, when force is applied, the first protective mesh unit (110) and the second protective mesh unit (120) open with the hinge module (130) as the axis as shown in FIG. 7, and when the applied force is removed, the first protective mesh unit (110) and the second protective mesh unit (120) close with the hinge module (130) as the axis as shown in FIG. 6 due to the action of the torsion spring (140). At the same time, as shown in FIG. 8, it is positioned on the outside of the sprinkler head (10) and protects the sprinkler head (10).

[0040] As such, in the case of this embodiment, unlike conventional methods, a torsion spring (140) with strong tension is used to fasten it in a clamping manner, so there is an advantage that it can be easily installed without using various tools or parts such as bolts.

[0041] In the first protective net unit (110) and the second protective net unit (120) where the torsion spring (140) is located, first and second clamp parts (141, 142) are provided to operate in a clamping manner and open the first protective net unit (110) and the second protective net unit (120). The first and second clamp parts (141, 142) form a type of handle. A worker can place their fingers on the first and second clamp parts (141, 142) and apply force in a direction that presses the first and second clamp parts (141, 142) to open the first protective net unit (110) and the second protective net unit (120) around the hinge module (130) as an axis, as shown in FIG. 7.

[0042] A latch (150) is provided on the first protective net unit (110) and the second protective net unit (120) at a position opposite the torsion spring (140), and serves to lock the first protective net unit (110) and the second protective net unit (120) so that they do not open arbitrarily. To ensure stable locking, the latch (150) is applied as a pair.

[0043] These latches (150) in this embodiment have a non-linear shape and are arranged to be rotatable with the latchke rotation axis (151) as the axis.

[0044] In addition, the first protective net unit (110) and the second protective net unit (120) are provided with first and second latch fixing bars (112, 122) to which a latch (150) is hooked and fixed.

[0045] Accordingly, as shown in FIG. 7, the first protective net unit (110) and the second protective net unit (120) are opened with the hinge module (130) as the axis, and after closing the first protective net unit (110) and the second protective net unit (120) as shown in FIG. 8, the work can be simply completed by rotating the latches (150) so that the latches (150) are fixed to the first and second latches fixing bars (112, 122).

[0046] According to the present embodiment, which operates based on the structure described above, it can be easily installed without using various tools or parts, including bolts, because it is fastened in a clamping manner using a torsion spring (140) with strong tension. Additionally, since an elastic body (114, 124) is applied to the part that engages with the sprinkler head (10), it can be tightly secured and easily fixed. Furthermore, it can be applied as a common size without the need for cumbersome distinction by size, and even if there are modifications after installation, modification work can be easily carried out.

[0047] FIG. 9 is a side view of a sprinkler head protection mesh according to a second embodiment of the present invention.

[0048] Referring to this drawing, the sprinkler head protection mesh (200) according to the present embodiment may also include first and second protection mesh units (210, 220), a hinge module (130), a torsion spring (140, torsion spring), and a latch (150), and through the organic combination and operation structure of these components, the sprinkler head (10, see FIG. 8) can be protected.

[0049] Meanwhile, in this structure, the first and second protective mesh units (210, 220) are made of transparent acrylic material. In this case, the sprinkler head (10) placed inside can be well protected, and since the sprinkler head (10) is clearly visible from the outside, it can provide convenience in maintenance.

[0050] Even when this embodiment is applied, since it is fastened in a clamping manner using a torsion spring (140) with strong tension, it can be easily installed without using various tools or parts including bolts, and since an elastic body (114, 124) is applied to the part that engages with the sprinkler head (10), it can be tightly sealed and easily fixed, and it can be applied as a common size without the need for cumbersome distinction by size, and even if there are modifications after installation, modification work can be easily carried out.

[0051] FIG. 10 is a plan view of a sprinkler head protection mesh according to a third embodiment of the present invention.

[0052] Referring to this drawing, the sprinkler head protection mesh (300) according to the present embodiment may also include first and second protection mesh units (110, 120), a hinge module (130), a torsion spring (140), a latch (150), and first and second elastic bodies (314, 324), and through the organic combination and operation structure of these components, the sprinkler head (10, see FIG. 8) can be protected.

[0053] Meanwhile, in this structure, a plurality of embossed protrusions (314a, 324a) for maintaining close contact with the sprinkler head (10) are formed on the walls of the first and second elastic bodies (314, 324) that contact the sprinkler head (10). When a plurality of embossed protrusions (314a, 324a) for maintaining close contact are formed on the walls of the first and second elastic bodies (314, 324) as in this embodiment, there is an advantage in that the sprinkler head (10) can be safely protected because it can be accurately made in contact even if the size of the sprinkler head (10) is slightly different.

[0054] Even when this embodiment is applied, it can be easily installed without using various tools or parts, such as bolts, because it is fastened using a clamping method with a torsion spring (140) of strong tension. Additionally, since an elastic body (314, 324) is applied to the part that engages with the sprinkler head (10), it can be tightly secured and easily fixed. Furthermore, it can be applied as a common size without the need for cumbersome distinction by size, and even if there are modifications after installation, modification work can be easily carried out.

[0055] FIG. 11 is a plan view of a sprinkler head protection mesh according to the fourth embodiment of the present invention.

[0056] Referring to this drawing, the sprinkler head protection mesh (400) according to the present embodiment may also include first and second protection mesh units (110, 120), a hinge module (130), a torsion spring (140, torsion spring), and a latch (150), and through the organic combination and operation structure of these components, the sprinkler head (10, see FIG. 8) can be protected.

[0057] The latch (150) is rotatable with the latch rotation axis (151) as the axis and serves to engage with the first and second latch fixing bars (112, 122) of the first and second protective mesh units (110, 120). At this time, a torsion coil spring (451) is further coupled to the latch rotation axis (151) region. The torsion coil spring (451) serves to elastically press the latch (150) in the direction of the arrow in FIG. 11. In other words, it elastically biases the latch (150) in the direction in which it engages with the first and second latch fixing bars (112, 122).

[0058] When a torsion coil spring (451) is further combined as in this embodiment, the work of fastening the latch (150) can be made easier, and since the latch (150) can be firmly fixed to the first and second latch fixing bars (112, 122), there is an advantage in that the convenience of the work can be increased.

[0059] Even when this embodiment is applied, since it is fastened in a clamping manner using a torsion spring (140) with strong tension, it can be easily installed without using various tools or parts including bolts, and since an elastic body (114, 124) is applied to the part that engages with the sprinkler head (10), it can be tightly sealed and easily fixed, and it can be applied as a common size without the need for cumbersome distinction by size, and even if there are modifications after installation, modification work can be easily carried out.

[0060] As such, the present invention is not limited to the described embodiments, and it is obvious to those skilled in the art that various modifications and variations can be made without departing from the spirit and scope of the invention. Accordingly, such modifications or variations should be deemed to fall within the scope of the claims of the present invention. Explanation of the symbols
