Description

  The present invention relates to a fixing structure and a hot water supply device, and more specifically, a fixing structure for fixing an object to be fixed to a fixing target, and a cover that is fixed to a box covering a pipe extending from the hot water supply device main body. The present invention relates to a water heater.

  In order to hide a plurality of pipes extending from the lower end of the water heater main body, a decorative cover (box) is provided below the water heater. A decorative cover is comprised from the casing comprised from the both sides | surfaces of a decorative cover, and the some beam which fixes these, and the cover which covers the front surface of a casing, for example. When the hot water supply device is installed outdoors, there is a risk that the cover may come off from the decorative cover (casing) and fall due to continuous vibration from wind or the like. Even if the cover is locked with a screw, the screw may be loosened and disengaged with an amplitude, and the danger of dropping remains.

  Thus, for example, in the fixing structure disclosed in Patent Document 1, a protruding piece is provided upward on a beam (a bracket fixed to the beam) installed on the upper part of the casing, and the protruding piece is provided on the upper part of the cover.

Therefore, the cover is further fixed to the casing by screwing a screw into the screw hole through an opening provided in the lower portion of the cover.

  However, in the fixing structure having the above-described configuration, when the piping cover of the hot water supply apparatus is fixed, the projecting piece provided on the beam upwards impairs the design aesthetics of the entire hot water supply apparatus. Also, once the decorative cover is assembled and the hot water supply body is placed on the cover, the cover interferes with the hot water supply body, so that even if the screw is removed, the cover will be detached from the decorative cover (casing) and will not fall. Absent. However, even if it is necessary to remove the cover for maintenance of piping, for example, it may be impossible to remove the hot water supply device main body without retreating, which causes inconvenience. In addition, it is conceivable that a construction contractor who performs maintenance of piping or the like cannot remove the cover even if the screws are removed, which may be disturbed and unnecessarily spend construction time.

  In addition, for example, the fixing structure disclosed in Patent Document 2 uses a fixture without providing a fixing structure on the cover, and hooks one end of the fixture to a fixed object and locks the other end with a screw. It is.

  However, the fixing structure having the above-described structure does not have a structure for stabilizing the latching portion, and is a structure used for a fixture with small vibration due to wind or the like, and can be used for a cover with large vibration due to wind or the like. It is not a thing.

Here, piping 15 (shown using a dotted line in FIG. 1) to which hot water or the like is supplied indoors from the lower end of the water heater main body 10 is attached via the wall surface V. It is extended indoors. Here, the leg portion 23 may be on the hot water supply device 1 side, or a leg portion standing in the form of an anchor bolt from the ground F side may be used. Instead of the leg portion 23, a beam 21g and a wall surface V, which will be described later, may be fixed so that the hot water supply device 1 does not contact the ground F.

  An exploded perspective view of the decorative cover 20 is given in FIG. The decorative cover 20 includes a casing (main body) 21 and a cover 22. In the figure, the casing (main body) 21 and the cover 22 are shown disassembled with respect to the reference axis L.

The main body 21 includes two flat plate-like side surfaces 21d and three beams 21a, 21c, and 21g having attachment pieces at both ends. Here, the beams 21a, before the protrusion 21a ₀ has protrusions 21a ₀ in (-Y side) has two screw holes 21f are formed. Two slits 21e are formed in the beam 21c.

  The two side surfaces 21d are arranged so that the inner surfaces are opposed to one side and the other side in the X-axis direction, and the front upper side (−Y, + Z side) ends of the front side lower side by the beam 21a. The ends on the (−Y, −Z side) are connected by a beam 21c, and the ends on the lower rear side (+ Y, −Z side) are connected by a beam 21g. The beams 21a and 21c and the beam 21g have one surface directed forward (−Y direction) and rearward (+ Y direction), the mounting piece is in contact with the inner surface of the side surface 21d, and a fixing tool such as a screw or a screw is used. It is fixed to the side surface 21d by welding. Note that the number, shape, material, and the like of the beam and the method of attaching to the side surface 21d are appropriately determined so as to obtain sufficient strength to support the side surface 21d.

  As shown in FIG. 1, the main body 21 is disposed under the hot water supply apparatus main body 10 (on the −Z side) so that the outer surfaces of the two side surfaces 21 d are substantially flush with the side surface of the housing 11 of the hot water supply apparatus main body 10. . Thereby, the piping 15 extending from the lower end of the water heater main body 10 is disposed indoors through the two side surfaces 21d vertically (Z-axis direction) and front-back (Y-axis direction). Become.

  The cover 22 includes a front surface 22a, an upper surface 22b and a lower surface 22c, and a flange 22d.

  The front surface 22a is formed in a convex shape in the -Y direction. In the vicinity of the upper end (+ Z end) of the front surface 22a, two holes 22f for allowing the fixture (screw 31) to pass are provided as will be described later.

  The upper surface 22b and the lower surface 22c are isosceles trapezoidal flat plates, and are respectively fixed to the upper end and the lower end of the front surface 22a. Two brackets 22e are fixed to the lower surface 22c at the + Y end (first portion) so as to face the front surface (−Y surface) of the beam 21c. The bracket 22e may be formed integrally with the lower surface 22c by bending the + Y end of the lower surface 22c in the + Z direction, or may be formed by fixing another member to the lower surface 22c by welding or the like. The structure of the bracket 22e will be described later.

Next, the relationship between the beam 21a, the two screw holes 21f provided in the beam 21a, the side surface 21d, and the cover 22 will be described with reference to FIG. FIG. 2B shows an arrow cross section of the P-plane in FIG. As shown in FIG. 2B, the screw hole 21f and the hole 22f are opposed to each other only when the casing (main body) 21 and the cover 22 face each other, and the beam 21a and the cover 22 can be closely fixed with the screw 31. it can.

FIG. 2C is a cross-sectional view taken along the Q plane in FIG. The locking piece 22e ₀ is received in the slit 21e. Note that FIG. 2D and FIG. 2E will be described later.

The flange 22d is formed by bending the ± X end of the front surface 22a in the + Y direction. As shown in FIG. 5A, the lower end (−Z end) is formed to be inclined by an angle θ ′ so as not to interfere with the beam 21c and the side surface 21d when the cover 22 is fixed to the main body 21. Yes. Here, it is assumed that the inclination angle θ ′ is equal to or smaller than the inclination angle θ of the oblique side portion of the locking piece 22e ₀ . Thus, FIG. 5 by tilting the cover 22 to the side surface 21d as shown in (B) (body 21), the hole portion (the engaging pieces 22e ₀ when fixing the cover 22 to the body 21 as will be described later The cover 22 can be slid in the X-axis direction with respect to the main body 21 when moving in the width direction within 21e ₂ .

If the inclination is shallow (within the interference angle shown in FIG. 5B) (side surface 21d is shown by a dotted line in FIG. 5B), as shown by the hatched portion in FIG. The side surface 21d interferes and cannot slide in the X-axis direction. A dot-dash line S in FIG. 5A and a circle mark in FIG. 5B indicate a rotation axis when a locking piece 22e _{0 (} to be described later) is brought into close contact with the inner bottom of the hole 21e _{2 and} tilted by θ. As indicated by the alternate long and short dash line S in FIG. 5A, the position where the locking piece 22e ₀ and the insertion portion 21e ₁ face each other is the position moved in the X-axis direction. There is no member that serves as a rotating shaft. In FIG. 5A, the cover 22 is inclined at an angle θ ′ around the rotation axis so that the flange 22d lower end (−Z end) does not interfere with the side surface 21d so as to move to the near side (−Y direction). The cover 22 can be slid in the + X axis direction with respect to the main body 21.
Further, as shown in FIG. 5A, the lower end of the flange 22d is inclined at an angle θ ′ so that the lower end (−Z end) of the flange 22d does not interfere with the side surface 21d when the cover 22 is inclined at an angle θ. Although formed, when the flange 22d is inclined at the angle θ ′, the minimum gap B between the point B ′ where the inclination of the flange 22d reaches the end face of the flange 22d and the side face 21d, and the lower end of the inclination of the flange 22d, If the relationship between the distance A between the rotation axes and the distance C between the end face of the flange 22d and the rotation axis does not satisfy A + B <C, the flange 22d cannot be used as an interference member.
Note that FIG. 5C shows a Z-axis horizontal cross section (R-plane cross section in FIG. 5A) in FIG.

Note that as the cover 22 does not interfere with the body 21, for example, as shown in FIG. 5 (D), may be formed a notch 21d ₀ through which the lower end of the flange 22d in a part of the side surface 21d of the body 21. The shape of the cutout 21d ₀ may employ any shape as impassable lower end of the flange 22d.

Further, the lower end of the flange 22d and forming with an angle theta 'tilt, may be provided 21d ₀ notched side 21d.

Also, when not tilt angle θ in the hole portion 21e ₂ a (locking pieces 22e ₀ so as not to interfere when moving the engaging piece 22e ₀ inclined angle θ in the width direction within the bore 21e _2, the FIG. 4 shows a flange 22d whose bottom end is inclined (by an angle θ ′) or a main body 21 having a notch 21d ₀ or in combination with the flange 22d or the main body 21 so as to interfere with movement in the width direction. the beam 21c (E), the cover 22 (the engaging pieces 22e ₀₎ may be formed interfering projection 21c ₂ when moving not inclined by a predetermined angle. In this case, if the cover 22 is sufficiently tilted, the cover 22 can move as shown in FIG. 4E, and if the tilt is shallow, the cover 22 cannot move due to interference with the projection 21c ₂ as shown in FIG. FIG. 4G is an enlarged cross-sectional view showing the interference between the protrusion 21c ₂ and the locking piece 22e ₀ . When the inclination is large (within the interference avoidance angle shown in the figure), the projection 21c ₂ and the locking piece 22e ₀ do not interfere as shown by the solid line, and when the inclination is small (interference angle shown in the figure). The projection 21c ₂ and the locking piece 22e ₀ interfere with each other as indicated by the dotted line.

  By fixing the cover 22 to the main body 21 and closing the opening on the front surface of the main body 21 (side surface 21d) to form the decorative cover 20, the piping 15 extending from the lower end of the hot water supply apparatus main body 10 is hidden.

  A fixing structure 30 for fixing the cover 22 to the main body 21 will be described.

  The fixing structure 30 includes a bracket 22e fixed to the cover 22 (lower surface 22c) and a beam 21c formed with a slit 21e.

FIG. 3A shows the configuration of the bracket 22e. Bracket 22e is a rectangular flat plate, the locking piece 22e ₀ of hook-shaped are cut out formed in its center. The locking piece 22e ₀ is bent at its base end and protrudes in a direction perpendicular to the bracket 22e (XZ plane) (+ Y direction).

The locking piece 22e ₀ has a distal end (width h2 (> h1)) wider than the base end (width h1). The lower portion of the distal end forms a locking portion extending downward (−Z direction) with respect to the proximal end. The upper end of the distal end extends upward (+ Z direction) with respect to the base end, and forms a hypotenuse that is inclined at an angle θ with respect to the bracket 22e (XZ plane). The inclination angle θ is in the range of 15 to 45 degrees, and 30 degrees is preferable. The length of the base end in the Y-axis direction is longer than the thickness of the beam 21c.

FIG. 3B shows the configuration of the slit 21e provided in the beam 21c. In the drawing, the back surface (+ Y surface) side of the beam 21c is shown. The slit 21e is formed by connecting a substantially square hole portion 21e ₂ and a rectangular insertion portion 21e ₁ to each other.

The width H in the Z-axis direction of the hole 21e ₂ is larger than the proximal end of the locking piece 22e ₀ (H> h1) and smaller than the distal end (H <h2). A groove 21C ₀ having a width larger than the thickness of the locking piece 22e ₀ (base end) and engageable with the base end is formed at a part of the lower edge (−Z side) of the hole 21e _2. Yes. The locking piece 22e ₀ has a distal end (width h2 (> h1)) wider than the base end (width h1). The lower portion of the distal end forms a locking portion extending downward (−Z direction) with respect to the proximal end. The upper end of the distal end extends upward (+ Z direction) with respect to the base end, and forms a hypotenuse that is inclined at an angle θ with respect to the bracket 22e (XZ plane). The inclination angle θ is in the range of 15 to 45 degrees, and 30 degrees is preferable. The length of the base end in the Y-axis direction is longer than the thickness of the beam 21c.

The insertion portion 21e ₁ extends upward (+ Z direction) from one end (−X end) of the hole portion 21e ₂ and continues to the outside of the beam 21c. The width in the X-axis direction is larger than the thickness of the locking piece 22e ₀ (base end).

A procedure for inserting the two locking pieces 22e ₀ into the two slits 21e and fixing the cover 22 to the casing (main body) 21 will be described.

  First, the ± X end of the cover 22 is held with both hands on the front side of the main body 21, and the cover 22 is inclined at a certain angle (for example, angles θ ′ to θ) with respect to the main body 21. 22e is arranged on the slit 21e of the corresponding beam 21c. Since the inclination of a certain angle is given, as shown in FIG. 2D, the cover 22 (flange 22d) and the main body 21 (side surface 21d) do not interfere with each other.

Next, the cover 22 is lowered downward (−Z direction) while maintaining the inclination. As a result, as shown in FIG. 4A, the base end of the locking piece 22e ₀ descends downward (in the direction of the black arrow in the figure) and is inserted into the insertion portion 21e ₁ of the slit 21e from above the beam 21c. Further, it abuts on the lower end (−Z end) of the hole 21e ₂ .

Next, the cover 22 is slid in the + X direction. Since the cover 22 is inclined at an angle θ ′ with respect to the main body 21, interference between the flange 22d and the side surface 21d as shown in FIG. As a result, as shown in FIG. 4B, the base end of the locking piece 22e ₀ can move in the hole 21e ₂ in the + X direction (the direction of the black arrow in the figure). In this way, the locking piece 22e ₀ is inserted into the hole 21e ₂ having a width larger than its base end and smaller than its tip end.

Incidentally, to hold the cover 22 in both hands so that for example the angle Shita'～shita, in reverse order, the locking pieces 22e ₀ by moving in a slit 21e, easily, the locking piece 22e ₀ Beam 21c That is, the cover 22 can be removed from the main body 21.

Further, by sliding the cover 22 in the + X direction, the base end of the locking piece 22e ₀ reaches the + X end of the hole 21e ₂ , and as shown in FIG. 4C, a fixed angle (for example, angles θ ′ to θ). When the inclination is restored, the base end of the locking piece 22e ₀ descends into the groove 21C ₀ formed in the back end of the hole 21e ₂ (in the direction of the black arrow in the figure) and fits into it. Thereby, as shown in FIG. 4 (D), that the base end of the locking piece 22e ₀ engages with the groove 21C _0, the engaging piece 22e ₀ is locked to the X-axis direction within the slit 21e .
Then the insertion portion 21e ₁ using 2 to (D), the groove 21C _0, the locking piece 22e _0, and the flange 22 d, the relationship between the side surface 21d will be described. FIG. 2D shows a cross-sectional view of the Q plane in FIG. As shown in FIG. 2 (D), the cover piece 22e ₀ and the insertion portion 21e ₁ are opposed to each other, that is, the two brackets 22e are respectively disposed on the slits 21e of the corresponding beams 21c, and the cover 22 is moved downward. When lowered in the −Z direction, the flange 22d at one end is between the side surface 21d and the side surface 21d, and the flange 22d at the other end is outside the side surface 21d. As shown in FIG. 2E, in this state, the flange 22d is connected to the beam 21a even if the cover 22 is fixed to the main body 21 with the screw 31 even if the cover 22 is not inclined at a certain angle (for example, the angles θ ′ to θ). The screw hole 21f and the hole 22f do not face each other due to interference, and the beam 21a and the cover 22 cannot be tightly fixed with the screw 31. That is, the locking piece 22e ₀ can be moved within the slit 21e, and the locking piece 22e ₀ can be fixed with the screw 31 only after the X-axis direction position of the locking piece 22e ₀ matches the X-axis direction position of the groove 21C ₀ .

As described above, by inserting the locking piece 22e ₀ into the slit 21e, the lower end of the leading end of the locking piece 22e ₀ is locked in the Y-axis direction by the edge of the hole 21e ₂ . Further, the oblique side portion at the upper end of the locking piece 22e ₀ is locked in the θx direction (the rotation direction around the X axis) by the edge of the hole 21e ₂ . Accordingly, the cover 22 can be tilted with respect to the main body 21 within the range of the inclination angle θ of the oblique side portion without the locking piece 22e ₀ (cover 22) being detached from the beam 21c (main body 21).

In the above description, the bracket 22e (cover 22) is inclined at a certain angle (for example, angles θ ′ to θ) with respect to the beam 21c, and the locking piece 22e ₀ is inserted into the slit 21e. The sliding piece 22e ₀ is slid in a state where the upper portion of the bracket 22e (cover 22) is inclined to the near side (−Y direction) within a predetermined range smaller than the inclination angle θ of the oblique side portion of the locking piece 22e _0. Is preferably inserted into the slit 21e and slid in the X-axis direction with an inclination of an angle θ.

After the base end of the locking piece 22e ₀ is locked by the groove 21C ₀ in the hole 21e ₂ and the cover 22 is positioned in the X-axis direction with respect to the main body 21, the cover 22 is positioned with respect to the front surface of the main body 21. When standing in parallel (releasing the inclination of a certain angle (for example, angles θ ′ to θ)), two holes 22f provided near the upper end (+ Z end) (second portion) of the front surface 22a of the cover 22 become beams 21a. Are communicated with the two screw holes 21f provided in the Y-axis direction. Therefore, finally, the screws 31 are screwed into the two screw holes 21f of the beam 21a through the two holes 22f of the cover 22, respectively. Thereby, the cover 22 (upper part) is detachably fixed to the main body 21 (beam 21a).

  In addition, when removing the cover 22 from the main body 21, it can remove easily by following a reverse procedure.

As described in detail above, by using the fixing structure 30 according to the present invention, the engaging pieces 22e ₀ by inserting the locking piece 22e ₀ into the hole 21e ₂ of the slit 21e provided in the beam 21c The cover 22 is fixed to the casing (main body) 21 by being locked by the edge of the hole 21e ₂ and detachably fixing the upper part of the cover 22 to the beam 21a. As a result, the cover 22 can be easily fixed to the casing (main body) 21, and even if the upper part of the cover 22 is unfixed (even if the screw is loosened by the amplitude of wind or the like), for example, the angle θ ′. Since the structure is such that it does not slide due to interference other than ± (θ−θ ′), the cover 22 is moved relative to the main body 21 when the cover 22 is inclined at an angle θ ′ to θ, for example, by wind in the −Y direction. Unless wind in the −X direction that slides in the X-axis direction is blown, the casing (main body) does not fall and can be used safely.

Further, the decorative cover 20 of the present embodiment, the shape of the tip of the engaging piece 22e ₀ (oblique sides), the engaging piece 22e ₀ which is inserted into the hole 21e in the _second slit 21e to the axis, the inclined portion The cover 22 can be tilted with respect to the main body 21 within the range of the tilt angle θ. Therefore, when simple maintenance such as observation of the piping 15 in the decorative cover 20 or the opening / closing operation of the gas stopper and the opening / closing operation of the water stopcock is required, the cover 22 is removed without removing the cover 31 from the main body 21. It is also possible to remove only the upper portion of the cover, and tilt the cover 22 toward the front (-Y side) to open only the upper portion of the cover 22 for processing.

  In addition, in the decorative cover 20 of the hot water supply device 1 of the present embodiment, the cover 22 (upper part) is detachably fixed to the main body 21 (beam 21a) by using the screw 31, but the present invention is not limited to this, and can be detachably attached. An appropriate fixing tool (fastener) may be used as long as it can be fixed.

Moreover, in the decorative cover 20 of the hot water supply device 1 of the present embodiment, the two brackets 22e constituting the fixing structure 30 and the beam 21c provided with the two slits 21e corresponding thereto are employed. The number of brackets 22e (locking pieces 22e ₀ ) and slits 21e is appropriately determined according to the strength. Although the slit 21e is formed in the beam 21c that fixes the side surface 21d of the casing (main body) 21, the bracket formed with the slit 21e may be fixed to the beam 21c by welding or the like. Thereby, the cover 22 can be stably fixed by the casing (main body) 21.

  Further, the decorative cover 20 of the hot water supply apparatus 1 of the present embodiment is configured such that the entire front surface of the main body 21 is opened and the front surface is covered with the cover 22 having the same shape. A configuration may be adopted in which a front surface is provided on 21 and an opening provided in a part thereof is covered with a cover having the same shape as or larger than the opening. Further, a configuration may be adopted in which the side surface, the rear surface, or the lower surface is opened instead of the front surface, and that one surface is covered with the cover 22.

Further, in the fixing structure 30 of the present embodiment, the slit 21e is formed from the hole 21e ₂ and the insertion portion 21e ₁ connected to the outside of the beam 21c, but the hole 21e ₂ can insert the locking piece 22e _0. As long as it is formed continuously with another possible hole, it is not always necessary to be formed outside the beam 21c, and any shape can be adopted. For example, another hole having a width wider than the tip of the locking piece 22e ₀ and the hole 21e ₂ are connected to form a slit 21e, and the locking piece 22e ₀ is inserted into the other hole from the tip to the base end. and, by moving the base end from another hole into the hole 21e _2, it is also possible to insert the locking piece 22e ₀ into the hole 21e _2. As a result, the locking piece 22e ₀ can be inserted into the hole 21e ₂ having a width larger than its base end and smaller than its distal end, and the locking piece 22e ₀ , that is, the cover 22 is inserted into the casing (main body) 21. Can be easily removed.

In the hot water supply apparatus 1 of the present embodiment, the decorative cover 20 is disposed under the hot water supply apparatus body 10 in order to hide the piping 15 extending from the lower end of the hot water supply apparatus body 10. However, the decorative cover 20 is arranged according to the extending direction of the piping 15. For example, the decorative cover 20 may be disposed on the hot water supply apparatus main body 10. A bracket 22e (locking piece 22e ₀ ) is provided at the upper end of the cover 22, a slit 21e is provided in the beam 21a at the upper part of the casing (main body) 21, and the lower part of the cover 22 is attached to and detached from the beam 21c at the lower part of the casing (main body) 21. It may be fixed as possible. Thereby, the cover 22 can be attached to the main body 21 so as to be tiltable about the upper end of the cover 22, thereby opening the lower part of the cover 22.
The interfering structure subject when the X-axis direction of the slide, the flange 22d and the beams 21a (FIG. 5 (B), the Fig. 5 (E)) and, limited to the engaging piece 22e ₀ and the beam 21c (FIG. 4 (F)) For example, the slope of the ± X end portion of the front surface 22a formed in a convex shape in the −Y direction and the ± X end portion of the protruding portion (projecting portion 21a ₀ ) of the beam 21a provided with the screw hole 21f are provided. What is necessary is just to set suitably.
Furthermore, in the above description, the bracket 22e (cover 22) is structured so as not to slide and interfere with the beam 21c except at angles θ ′ to θ, for example. It corresponds to the maximum possible tilt angle θ. However, if the structure is such that it slides only within a specific range not more than θ that does not include the maximum inclination angle θ that the bracket 22e (cover 22) can take (for example, as shown in FIGS. 4H and 5E). If the cover 22 is swaying within the specified range, for example, if the tilt is too large or too small, the cover 22 is moved with respect to the main body 21 by X. As long as there is no -X direction wind that slides in the axial direction, the casing (main body) does not fall off, and it can be used more safely, which is preferable.
The slide is not limited to movement in the + X axis direction, but the slit 21e shown in FIG. 3B may be mirror-inverted so that the movement direction is the −X axis direction slide. The slit 21e is formed in the beam 21c, and the bracket 22e. a is provided with the locking piece 22e _0, the engaging piece 22e ₀ to the beam 21c as shown in FIG. 4 (I), it may be a slit 21e provided in the bracket 22e.

  In addition, the fixing structure 30 of the present embodiment is not only usable in the decorative cover 20 of the hot water supply device 1 but can be used for anything that fixes an object to be fixed to an object to be fixed.

  The fixing structure of the present invention is suitable for fixing an object to be fixed to an object to be fixed. Moreover, the hot water supply device of the present invention can be easily removed without dropping the decorative cover that hides the pipe extending from the hot water supply device body, and is suitable for safe use.
