Description

[Technical Field]

[0001] The present invention relates to a sprinkler head protector that protects a sprinkler head that protrudes downward from a ceiling surface, and to a sprinkler equipment structure that uses this sprinkler head protector. [Background technology]

[0002] Conventionally, sprinkler heads are stored in the ceiling space (ceiling recess), and the water outlet at the bottom of the sprinkler head protrudes slightly into the room from an opening in the ceiling surface. The gap between the bottom of the sprinkler head and the ceiling opening is closed with a sealing plate or escutcheon (see Patent Documents 1 and 2). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2014-161395 [Patent Document 2] Japanese Patent Publication No. 2023-21400 Summary of the Invention [Problem to be solved by the invention]

[0004] To provide a sprinkler head protector and a sprinkler equipment structure that enable a sprinkler head to be installed on a ceiling surface even when the ceiling recess above the ceiling surface is low and the sprinkler head protrudes significantly downward from the ceiling surface. [Means for solving the problem]

[0005] A sprinkler head protective device of the first invention (for example, sprinkler head protective device 30 described below) is a sprinkler head protective device that protects a sprinkler head (for example, sprinkler head 10 described below) that protrudes downward from a ceiling opening (for example, ceiling opening 2 described below) in a ceiling surface (for example, ceiling surface 3 described below), and is characterized in that it comprises a tubular portion (for example, tubular portion 40 described below) that covers the outer side surface of the sprinkler head, and a gap cover (for example, gap cover 60 described below) that closes the gap between the tubular portion and the ceiling surface, the gap cover being annular with an outer diameter larger than that of the tubular portion, and the inner peripheral edge of the gap cover being formed with a recess (for example, recess 61 described below) into which the upper end of the tubular portion fits.

[0006] According to this invention, the sprinkler head protector includes a tubular portion that covers the outer peripheral side surface of the sprinkler head, and a gap cover that closes the gap between the tubular portion and the ceiling surface. Therefore, the tubular portion of the sprinkler head protector can protect the sides of the sprinkler head. Also, because the outer diameter of the gap cover is larger than that of the tubular portion, when the sprinkler head protector is attached to the ceiling surface, the gap cover can easily close the gap between the tubular portion and the ceiling surface. Therefore, the sprinkler head can be installed on the ceiling surface even if the sprinkler head protrudes significantly downward from the ceiling surface.

[0007] The sprinkler head protective device of the second invention is characterized in that the tubular portion comprises a tubular portion main body (e.g., tubular portion main body 41 described below) having a predetermined outer diameter, and a constriction portion (e.g., constriction portion 42 described below) provided at the lower end of the tubular portion main body and whose outer diameter decreases toward the bottom.

[0008] According to this invention, the constricted portion at the bottom of the tubular portion of the sprinkler head protective device is shaped so that its outer diameter becomes smaller as it goes downwards. Therefore, when the sprinkler head protective device is viewed from indoors, the tubular portion appears smaller, thereby reducing the sense of volume of the sprinkler head protective device. In addition, because the horizontal cross section of the tubular body, which is the upper part of the tubular part, is made uniform in shape, the height of the tubular part can be adjusted by cutting the upper part of the tubular part horizontally at any height position and fitting the cut part of the tubular body into the recess of the gap cover. This makes it possible to adjust the projection length of the sprinkler head protector from the ceiling surface to match the projection length of the sprinkler head from the ceiling surface.

[0009] A sprinkler equipment structure of a third invention (for example, sprinkler equipment structure 1 described below) is a sprinkler equipment structure that sprays water downward from a sprinkler head (for example, sprinkler head 10 described below), and is characterized by comprising: a ceiling surface (for example, ceiling surface 3 described below) in which a ceiling opening (for example, ceiling opening 2 described below) is formed; piping (for example, piping 20 described below) arranged in a space above the ceiling surface; a sprinkler head connected to the piping, protruding downward from the ceiling opening, and having a water outlet (for example, water outlet 11 described below) on its lower end; and the above-mentioned sprinkler head protector (for example, sprinkler head protector 30 described below) that is attached to the ceiling surface and protects the sprinkler head.

[0010] According to this invention, sprinkler heads that protrude significantly downward from the ceiling surface are protected by sprinkler head protectors. Therefore, even if the sprinkler head cannot be completely stored in the attic space and protrudes significantly downward from the ceiling surface, the sprinkler head can be installed on the ceiling surface. Furthermore, because it is not necessary to store the sprinkler head completely in the attic space, the ceiling surface can be set as high as possible, ensuring a spacious interior space. [Effects of the Invention]

[0011] According to the present invention, a sprinkler head protector and a sprinkler equipment structure can be provided that enable a sprinkler head to be installed on a ceiling surface even if the sprinkler head protrudes significantly downward from the ceiling surface. [Brief explanation of the drawings]

[0012] [Figure 1] 1 is a side view of a sprinkler system structure according to an embodiment of the present invention; [Figure 2] FIG. 1 is a longitudinal cross-sectional view of a sprinkler system structure. [Figure 3] FIG. 2 is an exploded view of a sprinkler head protector that constitutes the sprinkler equipment structure. DETAILED DESCRIPTION OF THE INVENTION

[0013] The present invention provides a sprinkler head protector that protects a sprinkler head body when the sprinkler head body is installed so that it protrudes downward from a ceiling surface. Specifically, the sprinkler head protector includes a cylindrical portion that covers the outer peripheral side surface of the sprinkler head, and a gap cover that closes the gap between the cylindrical portion and the ceiling surface. The gap cover is annular and has an outer diameter larger than that of the cylindrical portion, and the inner peripheral edge of the gap cover is formed with a recess into which the upper end of the cylindrical portion fits. Hereinafter, an embodiment of the present invention will be described with reference to the drawings. Fig. 1 is a side view of a sprinkler system structure 1 according to one embodiment of the present invention, and Fig. 2 is a vertical cross-sectional view of the sprinkler system structure 1. The sprinkler system structure 1 sprays water downward from a sprinkler head 10. The sprinkler equipment structure 1 comprises a ceiling surface 3 in which a ceiling opening 2 is formed, piping 20 arranged in an attic space 4 above the ceiling surface 3, a sprinkler head 10 connected to the piping 20, protruding downward from the ceiling opening 2 and having a water outlet 11 on its lower end, and a sprinkler head protector 30 attached to the ceiling surface 3 to protect the sprinkler head 10. Since the depth (height) of the attic space 4 is small, the sprinkler head 10 protrudes downward from the ceiling opening 2 by a large amount.

[0014] FIG. 3 is an exploded view of sprinkler head protector 30. The sprinkler head protector 30 comprises a tubular portion 40 that covers the outer peripheral side surface of the sprinkler head 10, a tip cover 50 that is attached to the lower end of the tubular portion 40 to close the gap between the tubular portion 40 and the side surface of the sprinkler head 10, and a gap cover 60 that is attached to the upper end of the tubular portion 40 to close the gap between the tubular portion 40 and the ceiling surface 3.

[0015] The cylindrical portion 40 includes a cylindrical main body 41 having a predetermined outer diameter, and a tapered portion 42 provided at the lower end of the cylindrical main body 41, the outer diameter of which decreases downward. The tip cover 50 comprises a circular annular portion 51 that engages with the lower end of the tubular portion 40, and a raised portion 52 that extends upward from the inner peripheral edge of the annular portion 51 and abuts against the side of the sprinkler head 10. The gap cover 60 is annular and has an outer diameter larger than that of the cylindrical portion 40, and the inner peripheral edge of the gap cover 60 is formed with a recess 61 into which the upper end of the cylindrical portion 40 fits.

[0016] According to this embodiment, the following effects are obtained. (1) The sprinkler head protector 30 includes a tubular portion 40 that covers the outer peripheral side surface of the sprinkler head 10 and a gap cover 60 that closes the gap between the tubular portion 40 and the ceiling surface 3. Therefore, the tubular portion 40 of the sprinkler head protector 30 can protect the side of the sprinkler head 10. Furthermore, since the outer diameter of the gap cover 60 is larger than that of the tubular portion 40, when the sprinkler head protector is attached to the ceiling surface 3, the gap cover 60 can easily close the gap between the tubular portion 40 and the ceiling surface 3, and the gap cover 60 can be tightly attached to the ceiling surface 3. Therefore, even if the sprinkler head 10 protrudes significantly downward from the ceiling surface 3, the sprinkler head 10 can be installed on the ceiling surface 3.

[0017] (2) The constricted portion 42, which is the lower part of the tubular portion 40 of the sprinkler head protector 30, is shaped so that the outer diameter becomes smaller as it goes downward. Therefore, when the sprinkler head protector 30 is viewed from an indoor space, the tubular portion 40 appears smaller, thereby reducing the sense of volume of the sprinkler head protector 30. Furthermore, since the horizontal cross section of the tubular body 41, which is the upper part of the tubular portion, is made to have a uniform shape, the tubular body 41 can be cut horizontally at any height and the cut portion of the tubular body can be fitted into the recess 61 of the gap cover 60, thereby adjusting the protrusion dimension of the sprinkler head protector 30 from the ceiling surface 3 to match the protrusion dimension of the sprinkler head 10 from the ceiling surface 3.

[0018] (3) Sprinkler heads 10 that protrude significantly downward from ceiling surface 3 are protected by sprinkler head protectors 30. Therefore, even if sprinkler heads 10 cannot be completely stored in attic space 4 and protrude significantly downward from ceiling surface 3, sprinkler heads 10 can be installed on ceiling surface 3. In addition, because there is no need to completely store sprinkler heads 10 in attic space 4, ceiling surface 3 can be set as high as possible to ensure a large indoor space.

[0019] The present invention is not limited to the above-described embodiment, and modifications and improvements within the scope of achieving the object of the present invention are included in the present invention. For example, in the above-described embodiment, the tubular portion 40 and the tip cover 50 that constitute the sprinkler head protector 30 are separate parts, but this is not limited to this, and the tubular portion 40 and the tip cover 50 may be integrated.
