Description

[Technical field]

[0001] The present invention relates to an adapter for preventing theft of a water-discharging device. [Background technology]

[0002] In recent years, water-discharging devices, such as showerheads, have become popular with high-function features such as water-saving, swing, large water droplet size, and microbubble functions. High-function showerheads are expensive, so there is a demand for anti-theft features for showerheads. An example of a showerhead with an anti-theft feature is the showerhead connecting unit described in Patent Document 1. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent Publication No. 2009-077895 Summary of the Invention [Problem to be solved by the invention]

[0004] The showerhead connecting unit disclosed in the above-mentioned Patent Document 1 comprises a first inner cylinder connected to a showerhead, a first inner cylinder connected to a liquid pipe, and an outer cylinder slidingly contacting the outside of the first inner cylinder and the second inner cylinder. When attaching and detaching the showerhead to the first inner cylinder attachment, the first inner cylinder and the outer cylinder can be fixed by a first rotation stop shaft, but during normal use, the showerhead and the outer cylinder rotate freely, so the showerhead cannot be removed from the showerhead connecting unit. Similarly, when attaching and detaching the liquid pipe to the second inner cylinder attachment, the second inner cylinder and the outer cylinder can be fixed by a second rotation stop shaft, but during normal use, the liquid pipe and the outer cylinder rotate freely, so the liquid pipe cannot be removed from the showerhead connecting unit.

[0005] However, in the shower head connecting unit described in Patent Document 1, the shower head and liquid pipe are designed to be removed using the first and second rotation stop shafts, respectively. However, since the shower head and liquid pipe can be removed using a rod-shaped member that is at hand, even without the first and second rotation stop shafts, there is a problem in that the anti-theft function is not sufficient.

[0006] In addition, the shower head connecting unit described in Patent Document 1 has a first stop hole and a second stop hole on the outer periphery for inserting the first and second rotation stop shafts, respectively, which makes them susceptible to dirt and is problematic from the standpoint of design. Furthermore, the appearance of these holes makes them easily reminiscent of the holes used for attachment and detachment, which is problematic from the standpoint of theft prevention.

Effect of the Invention

[0012] According to the first aspect of the water discharger theft prevention adapter of the present invention, at least one of the water discharger connection joint and the hose connection joint is provided with a jig engagement part on the outer periphery thereof for engaging with a jig, and when the jig is not engaged with the jig engagement part, the connection joint having the jig engagement part rotates relative to the adapter body, making it in a non-removable state, and when the jig is engaged with the jig engagement part, the connection joint having the jig engagement part can be prevented from rotating, making it in a removable state, so that the structure is simple and has a high anti-theft effect, and since the outer periphery of the connection joint can be provided with a jig engagement part for engaging with a jig, it is also excellent in terms of design. In addition, since the adapter body is rotatable, the shower head and the hose can rotate, so that the hose can be straightened out of twist or the direction can be adjusted while the shower head is fixed to the hook. Furthermore, by using standard products for the water discharger connection joint and the hose connection joint, they can be adapted to existing shower heads and hoses, respectively.

[0013] According to the first aspect of the water-discharging device anti-theft adapter, the outer periphery of the jig engagement part of the water-discharging device connection joint is exposed to the outside between the adapter body and the water-discharging device side connection part, and the outer diameter of the jig engagement part is smaller than the outer diameter of the part of the adapter body adjacent to the jig engagement part in the axial direction and the outer diameter of the part of the water-discharging device side connection part adjacent to the jig engagement part in the axial direction, so that it is not possible to engage with and operate the jig engagement part from the outside unless there is a dedicated jig. This effectively prevents the water-discharging device from being removed from the adapter body, and further enhances the anti-theft effect.

[0014] According to the first aspect of the water-discharging device anti-theft adapter, the outer periphery of the jig engagement part of the hose connection joint is exposed to the outside between the adapter body and the hose side connection part, and the outer diameter of the jig engagement part is smaller than the outer diameter of the part of the adapter body adjacent to the jig engagement part in the axial direction and the outer diameter of the part of the hose side connection part adjacent to the jig engagement part in the axial direction, so that it is not possible to engage with and operate the jig engagement part from the outside unless a special jig is used. This effectively prevents the hose from being removed from the adapter body, and further enhances the anti-theft effect.

[0015] Furthermore, according to the first aspect of the water-discharging device theft prevention adapter, the outer peripheral shape of the jig engagement portion is a shape in which straight sections and curved sections are repeated alternately, for example a shape in which arc sections and straight sections are repeated alternately in the circumferential direction, and the jig engages with at least two of the straight sections of the jig engagement portion. Therefore, unless a special tool is used as the jig, the jig cannot be engaged with and operated by the jig engagement portion, thereby further enhancing the theft prevention effect.

[0016] According to the second aspect of the adapter for preventing theft of a water discharger, the adapter body has a large diameter portion on the water discharger side connection portion side and a small diameter portion on the hose side connection portion side, an inner periphery of the large diameter portion faces an outer periphery of the water discharger connection joint and they are rotatable relative to each other in the circumferential direction, an outer periphery of the small diameter portion faces an inner periphery of the hose connection joint and they are rotatable relative to each other in the circumferential direction, a jig engaging portion of the water discharger connection joint is provided at an end portion of the water discharger connection joint opposite to the hose side connection portion and a jig engaging portion of the hose connection joint is provided at an end portion of the hose connection joint on the water discharger side connection portion side. Therefore, unless the jig engaging portion is engaged and operated with a dedicated tool, the water discharger cannot be removed from the adapter body and the hose cannot be removed from the adapter body, so that a more reliable anti-theft effect of the water discharger is achieved.

[0017] According to the second aspect of the water-discharging appliance theft prevention adapter, a water-discharging appliance side retaining member is provided between the inner periphery of the large diameter portion and the outer periphery of the water-discharging appliance connection joint, and the water-discharging appliance side retaining member has a gap adjustment function between the inner periphery of the large diameter portion and the outer periphery of the water-discharging appliance connection joint, so that the simple structure of providing the water-discharging appliance side retaining member provides a synergistic effect of preventing the water-discharging appliance connection joint from being removed and of adjusting the gap between the adapter body and the water-discharging appliance connection joint. Also, a hose-side retaining member is provided between the outer periphery of the small diameter portion and the inner periphery of the hose connection joint, and the hose-side retaining member has a gap adjustment function between the outer periphery of the small diameter portion and the inner periphery of the hose connection joint, so that the simple structure of providing the hose-side retaining member provides a synergistic effect of preventing the hose connection joint from being removed and of adjusting the gap between the adapter body and the hose connection joint.

[0018] Moreover, according to the second aspect of the water-discharging device theft prevention adapter, a water-discharging device side seal member is provided between the inner periphery of the large diameter portion and the outer periphery of the water-discharging device connection joint, and a hose side seal member is provided between the outer periphery of the small diameter portion and the inner periphery of the hose connection joint. This not only ensures a sealing effect, but also does not require special specifications for the seal member, so that, for example, a commercially available O-ring can be used, and there is a high degree of freedom in selecting the seal member.

[0019] According to the second aspect of the water-discharging device anti-theft adapter, a taper is provided on the inner circumference of the seal member placement portion of the hose-side connection portion, which increases in diameter as it approaches the water-discharging device-side connection portion, so that a force acts on the seal member such as an O-ring in the seal member placement portion in a direction away from the male thread of the hose connection joint or the female thread on the inside of the hose-side connection portion, i.e., in the direction of the water-discharging device-side connection portion, thereby preventing the seal member from coming into contact with the male thread or the female thread and breaking. Also, by providing a taper on the outer circumference of the seal member placement portion of the hose connection joint, which decreases in diameter as it approaches the water-discharging device-side connection portion, the seal member can be prevented from coming into contact with the male thread or the female thread and breaking, as in the above case. Moreover, the taper can be provided in either one or both of the above ways, so that the freedom of design of the water-discharging device anti-theft adapter for preventing the seal member from coming into contact with the male thread or the female thread and breaking can be increased.

[0020] According to the third aspect of the present invention, the water-discharging appliance anti-theft adapter can be applied to a shower head as a water-discharging appliance to be anti-thefted. An existing shower head is connected to a hose by connecting a water-discharging appliance side connector to a hose side connector, and by inserting the water-discharging appliance anti-theft adapter of this aspect between the water-discharging appliance side connector and the hose connector, it is possible to add an anti-theft function to the existing shower head with a simple configuration and simple procedure.

[0021] According to the water-discharging device anti-theft adaptor of the fourth aspect of the present invention, the arrangement pattern of the jig engagement portion can be selected from any of the following (1) to (4). a first arrangement pattern in which the jig engagement portion of the joint is provided at an end portion of the water-discharging device connection joint opposite to the hose-side connection portion side, and the jig engagement portion of the hose connection joint is provided at an end portion of the hose connection joint on the water-discharging device-side connection portion side; (2) A second arrangement pattern in which the jig engagement portion of the water-discharging equipment connection joint is provided at an end portion of the water-discharging equipment connection joint opposite to the hose side connection portion, and the jig engagement portion of the hose connection joint is provided at an end portion of the hose connection joint opposite to the water-discharging equipment side connection portion; (3) A third arrangement pattern in which the jig engagement portion of the water-discharging device connection joint is provided at the end portion of the water-discharging device connection joint on the hose side connection portion side, and the jig engagement portion of the hose connection joint is provided at the end portion of the hose connection joint opposite to the water-discharging device side connection portion side; (4) A fourth arrangement pattern in which the jig engagement portion of the water-discharging equipment connection joint is provided at the end portion of the water-discharging equipment connection joint on the hose side connection portion side, and the jig engagement portion of the hose connection joint is provided at the end portion of the water-discharging equipment connection joint on the hose side connection portion side. Therefore, there is a wide range of design possibilities for the arrangement of the jig engagement portion, which increases the design freedom of the water-spill device anti-theft adapter of this embodiment, making it possible to apply the water-spill device anti-theft adapter of this embodiment to water-spill devices and hoses of various specifications.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0023] Hereinafter, the water-discharging device anti-theft adapter according to the embodiment of the present invention will be described in detail with reference to the drawings. However, the following embodiment is an example of a water-discharging device anti-theft adapter for embodying the technical idea of ​​the present invention, and the present invention is not limited to these, and can be equally applied to other embodiments included in the scope of the claims. In the embodiment of the present invention, a shower head is exemplified as a specific example of a water-discharging device, but this is merely one example, and the water-discharging device anti-theft adapter of this embodiment is not limited to a shower head, but can be applied to any type of water-discharging device.

[0024] [Embodiment 1] An illumination device according to a first embodiment of the present invention will be described with reference to FIGS.

[0025] Fig. 1 is a perspective view of an application example of the water-discharging appliance anti-theft adapter of the first embodiment, and Fig. 2 is an external view of the water-discharging appliance anti-theft adapter part of Fig. 1. In the use example of Fig. 1, a shower head 10 as a water-discharging appliance is connected to a hose 20 via a water-discharging appliance anti-theft adapter 30. A nozzle 11 is provided on the water-discharging side of the shower head 10, and a water-discharging appliance side connection part 12 is provided on the water-intake side. In addition, a hose side connection part 21 is provided on the water-outlet side of the hose 20. The water-discharging appliance anti-theft adapter 30 is rotatably attached to each of the water-discharging appliance side connection part 12 and the hose side connection part 21.

[0026] As described later, the portions having a small diameter at both ends in the axial direction of the water-discharging tool anti-theft adapter 30 are the water-discharging tool side jig engaging portion 41 and the hose side jig engaging portion 51 .

[0027] In an existing shower facility, the water-discharging device side connection part 12 of the shower head 10 is directly connected to the hose side connection part 21. An example of an installation in which the water-discharging device anti-theft adapter 30 of this embodiment is applied to this existing shower facility to add an anti-theft function will be described. First, in the existing shower facility, the connection between the water-discharging device side connection part 12 and the hose side connection part 21 is released. Specifically, for example, when the male thread of the water-discharging device side connection part 12 and the female thread of the hose side connection part 21 are screwed together, the connection due to the screwing is released by rotating them relatively to the left in the case of right-handed threads.

[0028] Next, the hose side connection joint 50 at the hose 20 side end of the water-discharge appliance anti-theft adapter 30 is attached to the hose side connection part 21 by operating the hose side jig engagement part 51 with a jig described later.

[0029] Next, the water-discharging appliance side connection joint 40 at the water-discharging appliance 10 side end of the water-discharging appliance anti-theft adapter 30 is attached to the water-discharging appliance side connection part 12 by operating the water-discharging appliance side jig engagement part 41 with a jig described later. In this way, as in the application example of Figure 1, the water-discharging appliance anti-theft adapter 30 of this embodiment can be applied to an existing shower facility to add an anti-theft function. The water-discharging appliance anti-theft adapter 30 of this embodiment is designed to have dimensions and a shape that are applicable to a commonly available shower hose assembly and shower head 10, as described later.

[0030] Fig. 3 is a cross-sectional view of the water-discharging device anti-theft adapter portion of Fig. 2. The water-discharging device anti-theft adapter 30 is composed of an adapter body 31, a water-discharging device connecting joint 40, and a hose connecting joint 50.

[0031] The adapter body 31 has a large diameter portion 32, a small diameter portion 33, and a step portion 34 connecting the large diameter portion 32 and the small diameter portion 33. A retaining member accommodating groove 32a for accommodating a water-discharging device side retaining member 47 is provided on the inner circumference of the large diameter portion 32. The water-discharging device side retaining member 47 is an annular member for preventing the water-discharging device connecting joint 40 from coming off in the thrust direction from the large diameter portion 32. Since it is necessary to ensure strength against stress in order to exert the retaining function, it is constituted by a ring made of a material such as metal or ceramic, although it is not particularly limited. The material of the water-discharging device side retaining member 47 is not limited to metal and ceramic, and it is also possible to adopt a material such as resin as long as strength is ensured.

[0032] A water-discharging device connection joint 40 is disposed inside the large diameter portion 32 of the adapter body 31 so as to be rotatable relative to the adapter body 31 in the circumferential direction. A water-discharging device side jig engagement portion 41 is provided at the upper end of the water-discharging device connection joint 40, projecting in a flange shape toward the outer periphery, and the outer periphery is exposed to the outside. A female thread 42 is provided on the inner periphery of the water-discharging device connection joint 40, and this female thread 42 is screwed into a male thread 13 provided on the outer periphery of the water-discharging device side connection portion 12. A thrust receiving portion 43 is provided at the lower end of the water-discharging device connection joint 40, and the thrust receiving portion 43 is slidable relative to the upper portion of the step portion 34 of the adapter body 31.

[0033] A retaining member facing portion 44 that faces the retaining member 47 on the water-discharging device connection joint 40 is provided along the circumference. A seal member accommodating groove 45 that accommodates a seal member 48 on the water-discharging device side is provided above the retaining member facing portion 44. The seal member 48 on the water-discharging device side is, for example, an O-ring, but is not limited to, a particular type. The seal member 48 on the water-discharging device side acts as a seal to prevent liquid leakage between the inner circumference of the large diameter portion 32 and the inner circumference of the water-discharging device connection joint 40. In addition to providing a reliable sealing effect, the seal member does not require special specifications, so that a commercially available O-ring can be used, for example, and the freedom of selection of the seal member can be increased.

[0034] In addition, a sealing O-ring 14 is provided on the inner circumference of the water-discharging equipment side jig engagement portion 41 of the water-discharging equipment connection joint 40 and on the upper corner of the male thread 13 of the water-discharging equipment side connection portion 12. The O-ring 14 has the effect of preventing liquid leakage from between the female thread 42 on the inner circumference of the water-discharging equipment connection joint 40 and the male thread 13 on the outer circumference of the water-discharging equipment side connection portion 12. The sealing O-ring 14 not only reliably exerts a sealing effect, but also does not require special specifications as a sealing member, so that, for example, a commercially available O-ring or an O-ring normally used for the shower head 10 or hose 20 can be used as is, and there is a high degree of freedom in selecting a sealing member.

[0035] The water-discharging device side retaining member 47 is provided facing the retaining device facing portion 44 and protruding from the inner circumference of the retaining device accommodating groove 32a, so that the protruding portion engages with the inner circumference of the retaining device facing portion 44 to prevent the water-discharging device from coming off. The water-discharging device side retaining member 47 also has the function of ensuring an appropriate clearance between the inner circumference of the large diameter portion 32 and the outer circumference of the water-discharging device connecting joint 40. The appropriate clearance here is a clearance that is uniform in the circumferential direction, allows misalignment between the axis of the large diameter portion 32 and the axis of the water-discharging device connecting joint 40, and allows the large diameter portion 32 and the water-discharging device connecting joint 46 to rotate smoothly in the circumferential direction even when the axes are misaligned.

[0036] A retaining member facing portion 33a facing the hose side retaining member 57 is provided on the outer periphery of the small diameter portion 33 of the adapter body 31. A seal member accommodating groove 33b for accommodating a hose side seal member 58 is provided above the retaining member facing portion 33a. The hose side seal member 58 is not particularly limited, but may be, for example, an O-ring. The hose side seal member 58 acts as a seal to prevent liquid leakage between the outer periphery of the small diameter portion 33 and the inner periphery of the hose connection joint 50. In addition to providing a reliable sealing effect, the hose side seal member 58 does not require special specifications as a seal member, so that, for example, a commercially available O-ring can be used, increasing the freedom of selection of the seal member.

[0037] Further, a sealing O-ring 24 is provided between the upper part of the female thread 23 of the hose side connection portion 21 and the corner between the upper part of the male thread of the hose connection fitting 50 and the hose side jig engagement portion 50. The sealing O-ring 24 acts as a seal to prevent liquid leakage between the male thread 52 of the hose connection fitting 50 and the female thread 23 of the hose side connection portion. The sealing O-ring 24 not only reliably exerts a sealing effect, but also does not require special specifications as a sealing member, so that, for example, a commercially available O-ring or an O-ring normally used for the showerhead 10 or hose 20 can be used as is, increasing the freedom of selection of the sealing member.

[0038] A hose connection joint 50 is disposed on the outside of the small diameter portion 33 of the adapter body 31 so as to be rotatable relative to the hose connection joint 50 in the circumferential direction. A hose side jig engagement portion 51 is provided at the upper end of the hose connection joint 50 so as to protrude like a flange, and its outer periphery is exposed to the outside. A male thread 52 is provided on the outer periphery of the hose connection joint 50, and this male thread 52 is screwed into a female thread 23 provided on the inner periphery of the hose side connection portion 21. A thrust receiving portion 53 is provided at the upper end of the hose connection joint 50, and the thrust receiving portion 53 is slidable between the lower portion of the stepped portion 34 of the adapter body 31 and the lower portion of the stepped portion 34.

[0039] The hose connection joint 50 has an inner periphery provided with a retaining member accommodating groove 54 for accommodating a hose side retaining member 57. The hose side retaining member 57 is an annular member for preventing the hose connection joint 50 from coming off in the thrust direction from the small diameter portion 33. Since it is necessary to ensure strength against stress in order to exert the retaining function, it is composed of a ring made of a material such as metal or ceramics, similar to the water discharger side retaining member, although there is no particular limitation. The material of the hose side retaining member 57 is not limited to metal and ceramics, and materials such as resin can be used as long as strength can be ensured.

[0040] The hose fitting-side anti-slip member 57 faces the anti-slip member facing portion 33a and is provided protruding from the outer periphery of the hose-side anti-slip member accommodating groove 54, so that the protruding portion engages with the outer periphery of the anti-slip member facing portion 33a to provide a function of preventing the hose fitting from slipping out. The hose-side anti-slip member 57 also has the function of ensuring an appropriate clearance between the outer periphery of the small diameter portion 33 and the inner periphery of the hose connection joint 50. The appropriate clearance here is a clearance that is uniform in the circumferential direction, allows for misalignment between the axis of the small diameter portion 33 and the axis of the hose connection joint 50, and allows the small diameter portion 33 and the hose connection joint 50 to rotate smoothly in the circumferential direction even when the axes are misaligned.

[0041] A hose 20 is fixed to the inner peripheral lower end of the hose side connection portion 21 in a sealed state by a hose inner seal 22 .

[0042] Fig. 4 is an explanatory diagram of the dimensions of the water-discharging device anti-theft adapter part of Fig. 3. The same components as those in Fig. 3 are given the same reference numerals and description will be omitted. The outer periphery of the water-discharging device side jig engagement part 41 of the water-discharging device connection joint 40 is exposed to the outside between the adapter main body 31 and the water-discharging device side connection part 12 (part β1). The outer diameter γ of the water-discharging device side jig engagement part 41 is smaller than the outer diameter ζ1 of the part of the large diameter part 32 of the adapter main body 31 adjacent in the axial direction to the water-discharging device side jig engagement part 41, and the outer diameter ε of the part of the water-discharging device side connection part 12 adjacent in the axial direction to the water-discharging device side jig engagement part 41. That is, γ<ε,γ<ζ1 (1) It is set so that:

[0043] The outer periphery of the hose side jig engagement portion 51 of the hose connection fitting 50 is exposed to the outside between the adapter body 31 and the hose side connection portion 21 (portion β2). The outer diameter δ of the hose side jig engagement portion 51 is smaller than the outer diameter ζ2 of the portion of the adapter body 31 adjacent to the hose side jig engagement portion 51 in the axial direction, and the outer diameter η of the portion of the hose side connection portion 21 adjacent to the hose side jig engagement portion 51 in the axial direction. That is, δ<η,γ<ζ2 (2) It is set so that:

[0044] The relationship between the outer diameter γ of the water-discharging device side jig engaging portion 41 and the outer diameter δ of the hose side jig engaging portion 51 is not particularly limited, and is arbitrary as long as it satisfies the conditions of formula (1) and formula (2). δ<γ (3) δ = γ (4) δ>γ (5) In the example of Fig. 4, the relationship between the shape of the showerhead 10 and the diameter of the hose 20 is given by formula (3). Regardless of whether the relationship between the outer diameter γ of the water-discharging device side jig engagement portion 41 and the outer diameter δ of the hose side jig engagement portion 51 is formula (3), formula (4), or formula (5), the same jig 70 can be used, as described below.

[0045] Recent shower heads 10 have become larger with an emphasis on functionality, and there are an increasing number of cases where there is no room for clearance between the shower booth ceiling and the head, so the dimensions for installing the water-discharging device anti-theft adapter 30, i.e., the total height dimension α, which is the axial dimension exposed on the outer periphery of the water-discharging device anti-theft adapter 30, is made compact, for example, 18 mm or less. The large diameter portion 32 and the water-discharging device connecting joint 46, and the small diameter portion 33 and the hose connecting joint 50 can freely rotate when an external force in the rotational direction is applied, so the water-discharging device anti-theft adapter 30 has an anti-theft function.

[0046] After the installation of the water-discharging device anti-theft adapter 30 is complete, even if the hose 20 is held by hand and rotated in the direction of removal, the water-discharging device anti-theft adapter 30 will spin freely, and the hose 20 cannot be removed unless a special tool is used as a jig with a specific shape described below. Similarly, after the installation of the water-discharging device anti-theft adapter 30 is complete, even if the showerhead 10 is held by hand and rotated in the direction of removal, the water-discharging device anti-theft adapter 30 will spin freely, and the showerhead 10 cannot be removed unless a jig with a specific shape described below is used.

[0047] From the viewpoint of theft prevention, the outer diameter shape of the water discharger side jig engaging portion 41 and the hose side jig engaging portion 51, which are the jig engaging portions with which the jig 70 as a dedicated tool engages, is structured so that general circulation tools such as radio pliers and pliers cannot easily reach. Specifically, the outer diameter γ of the β1 portion, which is the outer exposed portion of the outer periphery of the water discharger side jig engaging portion 41, is smaller than the dimensions ε and ζ1. In addition, the outer diameter δ of the β2 portion, which is the outer exposed portion of the outer periphery of the hose side jig engaging portion 51, is smaller than the dimensions η and ζ2. Furthermore, the dimensions β1 and β2 are set as small as possible as long as they are larger than the thickness dimension d of the jig 70. In various shower heads 10 and hoses 20 that are generally available, the minimum diameter of ε is 27 mm, and the minimum diameter η of η is 25 mm. In addition, the thickness of the jig 70 is not particularly limited, but can be set to about 2 mm, for example, in relation to the material and strength of the metal. Although not particularly limited, in this embodiment, for example, the dimensions of ε-γ, η-δ, β1-d, and β2-d are set to a dimensional difference of 0.2 mm, taking into consideration that they cannot be manipulated with general distribution tools, that they can be attached and detached only when the jig 70 is used, and manufacturing tolerances, etc. γ≦26.8mm (6) δ≦24.8mm (7) β1≦2.2mm (8) β2≦2.2mm (9) By so doing, a dimension is adopted that makes it impossible to operate the jig engagement portion with a general tool.

[0048] 5 is an explanatory diagram of the jig 70 of the water-discharging device anti-theft adapter 30 of the first embodiment. The jig 70 includes an operation portion 71, a first engagement claw portion 72, and a second engagement claw portion 73. The outer peripheral shape of the water-discharging device side jig engagement portion 41 is a shape in which straight line portions 41a and arc portions 41b as curved portions are alternately repeated in the circumferential direction. A first engagement surface 72a, which is an inner surface of the first engagement claw portion 72, engages with one straight line portion 41a, and a second engagement surface 73a, which is an inner surface of the second engagement claw portion 73, engages with the other straight line portion 41a, so that an operator can operate the water-discharging device side jig engagement portion 41 with the jig 70 by holding the operation portion 71 of the jig 70 in his / her hand and operating it. 5, the outer peripheral shape of the water-discharging device side jig engagement portion 41 has a shape in which straight line portions 41a and arcuate portions 41b are alternately repeated five times in the circumferential direction, and has five straight line portions 41a, and these five straight line portions 41a form line segments of each side of a regular pentagon. For this reason, the angle between the first engagement surface 72a and the second engagement surface 73a is set to 36°, which is the angle formed by two sides sandwiching one of the five sides of the regular pentagon. Furthermore, the thickness dimension d of the jig 70 is not particularly limited, but is set to 2 mm, for example. In this case, the dimension β1 is calculated from equation (8) as follows: d=2mm≦β1≦2.2mm (10) By setting it in this way, the first engagement surface 72a and the second engagement surface 73a become substantially parallel to the two straight line parts 41a on the outer periphery of the water-discharging equipment side jig engagement part 41, so that the water-discharging equipment side jig engagement part 41 can be operated only when the jig 70 is used.

[0049] 5, the outer peripheral shape of the water-discharging device side jig engaging portion 41 is described as a shape in which the straight portion 41a and the arc portion 41b are alternately repeated five times in the circumferential direction, but this embodiment is not limited to this, and any shape may be used as long as it is a shape that cannot be easily reached by a general distribution tool, and for example, a shape in which the straight portion 41a and the arc portion 41b are alternately repeated seven times or more, for example, seven times or nine times, or a shape in which the straight portion 41a is not a regular polygon, etc. may be adopted. Also, in a polygonal shape in which only the straight portions 41a are continuous, there is a risk that the corners sandwiched between the straight portions 41a and the adjacent straight portions 41a may easily engage with a tool, so it is preferable to provide arc portions between the straight portions 41a. Here, in the example of Figure 5, as an example of a curved portion, the multiple arc portions 41b are all described as being arcs on the same circumference, but the curved portion of this embodiment is not limited to this, for example, the multiple arcs do not necessarily have to be arcs on the same circumference, and the curved portion is not limited to an arc, and may be, for example, a shape that convex outwardly so as to follow the outer periphery of an arbitrary ellipse, a spline curve, or the like.

[0050] In FIG. 5, the water-discharging device side jig engaging portion 41 is illustrated, but the hose side jig engaging portion 51 also has an outer peripheral shape in which straight line portions 51a and arc portions 51b are alternately repeated five times in the circumferential direction, and has five straight line portions 51a, and these five straight line portions 51a can be line segments of each side of a regular pentagon. That is, in this case, the reference numeral 41 in FIG. 5 is replaced with 51, the reference numeral 41a with 51a, and the reference numeral 41b with 51b. In this case, the same jig 70 as in FIG. 5 can be used for the hose side jig engaging portion 51. The thickness dimension d of the jig 70 is not particularly limited either, but is set to, for example, 2 mm as in the case of FIG. 5. In this case, the dimension β2 is calculated from equation (9) as follows: d=2mm≦β2≦2.2mm (11) By setting it in this manner, the first engagement surface 72a and the second engagement surface 73a become substantially parallel to the two straight line portions 51a on the outer periphery of the hose side jig engagement portion 51, so that the hose side jig engagement portion 51 can be operated only when the jig 70 is used.

[0051] Here, the hose side jig engagement part 51 has been described using FIG. 5, which is the same as the water-discharging tool side jig engagement part 41. However, the outer diameter δ of the hose side jig engagement part 51 and the outer diameter γ of the water-discharging tool side jig engagement part 41 do not necessarily have to be the same. In the example of FIG. 4, it is illustrated as δ<γ. Even in this case, if the water-discharging tool side jig engagement part 41 and the hose side jig engagement part 51 are similar in shape and the angle between the first engagement surface 72a and the second engagement surface 73a is set to 36°, which is the angle formed by two sides sandwiching one side of the five sides of a regular pentagon, it is possible to operate both the water-discharging tool side jig engagement part 41 and the hose side jig engagement part 51 using the same jig 70 regardless of the outer diameter. In other words, if the water-discharging tool side jig engagement part 41 and the hose side jig engagement part 51 are set, for example, as in the above formulas (6) and (7), they can be operated using a common jig 70 regardless of the outer diameters δ and γ.

[0052] 6 is an explanatory diagram of the procedure for removing the shower head 10 from the water-discharging device anti-theft adapter 30 of the first embodiment. The first engagement surface 72a of the first engagement claw portion 72 of the jig 70 and the second engagement surface 73a of the second engagement claw portion 73 of the jig 70 are aligned with the outer periphery of the water-discharging device side jig engagement portion 41 so that they are parallel to the two straight portions 41a, respectively, and the jig 70 is pressed against the jig 70, thereby fixing the water-discharging device connection joint 40. In this state, when the water-discharging device side connection portion 12 is rotated in the direction of the arrow in FIG. 6, the female thread 42 of the water-discharging device connection joint 40 and the male thread 13 of the water-discharging device side connection portion 12 can be released from the screw engagement, so that the shower head 10 can be removed from the water-discharging device anti-theft adapter 30 only when the jig 70 of the specific shape shown in FIG. 5 is used.

[0053] Also, when attaching the water-discharging appliance anti-theft adapter 30 to the showerhead 10, the water-discharging appliance connection fitting 40 can be fixed in the same manner with the jig 70, and the water-discharging appliance side connection part 12 can be rotated in the direction opposite to the arrow in Figure 6, thereby screwing the male thread 13 of the water-discharging appliance side connection part 12 into the female thread 42 of the water-discharging appliance connection fitting 40.

[0054] 7 is an explanatory diagram of a procedure for removing the hose 20 from the water-discharging device anti-theft adapter 30 of the first embodiment. The first engagement surface 72a of the first engagement claw portion 72 of the jig 70 and the second engagement surface 73a of the second engagement claw portion 73 of the jig 70 are aligned with the outer periphery of the hose-side jig engagement portion 51 so as to be parallel to the two straight portions 51a, respectively, and the jig 70 is pressed against the jig 70, thereby fixing the hose connection joint 50. In this state, when the hose-side connection portion 21 is rotated in the direction of the arrow in FIG. 7, the male thread 52 of the hose connection joint 50 and the female thread 23 of the hose-side connection portion 21 can be released from the screwing. Therefore, the hose 20 can be removed from the water-discharging device anti-theft adapter 30 only when the jig 70 having the specific shape shown in FIG. 5 is used.

[0055] Also, when attaching the water-discharge appliance anti-theft adapter 30 to the hose 20, the hose connection fitting 50 can be fixed in the same manner with the jig 70 and the hose side connection part 21 can be rotated in the direction opposite to the arrow in Figure 7, thereby screwing the female thread 23 of the hose side connection part 21 into the male thread 52 of the hose side connection fitting 50.

[0056] According to the water-discharging appliance anti-theft adapter 30 of this embodiment, the outer periphery of at least one of the connection joints, the water-discharging appliance connection joint 40 and the hose connection joint 50, is provided with jig engagement portions 41, 51 that engage with a jig. When the jig 70 is not engaged with the jig engagement portions 41, 51, the connection joints 40, 50 having the jig engagement portions 41, 51 rotate relative to the adapter body 31 and are in an unremovable state. When the jig 70 is engaged with the jig engagement portions 41, 51, the connection joints 40, 50 having the jig engagement portions 41, 51 can be prevented from rotating and are in a removable state. Therefore, the structure is simple and has a high anti-theft effect, and further, the jig engagement portions 41, 51 that engage with the jig 70 can be provided on the outer periphery of the connection joints 40, 50, so that the design is also excellent. In addition, because the adapter body 30 is rotatable, the shower head 10 and the hose 20 can rotate, making it possible to straighten out any twists in the hose 20 or adjust the direction of the shower head 10 while it is still fixed to the hook. Furthermore, by using standard products for the water discharger connection joint 40 and the hose connection joint 50, they can be made compatible with existing shower heads 10 and hoses 20, respectively.

[0057] Moreover, according to the water-discharging appliance anti-theft adapter 30 of this embodiment, the outer periphery of the jig engagement portion 41 of the water-discharging appliance connection joint 40 is exposed to the outside between the adapter body 31 and the water-discharging appliance side connection portion 12, and the outer diameter γ of the jig engagement portion 41 is smaller than the outer diameter ζ1 of the portion of the adapter body 31 adjacent to the jig engagement portion 41 in the axial direction and the outer diameter ε of the portion of the water-discharging appliance side connection portion 12 adjacent to the jig engagement portion 41 in the axial direction, so that it is not possible to engage with and operate the jig engagement portion 41 from the outside unless there is a dedicated jig 70. This effectively prevents the water-discharging appliance 10 from being removed from the adapter body 30, and further enhances the anti-theft effect.

[0058] Moreover, according to the water-discharging device anti-theft adapter 30 of this embodiment, the outer periphery of the jig engagement portion 51 of the hose connection joint 50 is exposed to the outside between the adapter body 30 and the hose side connection portion 21, and the outer diameter δ of the jig engagement portion 51 is smaller than the outer diameter ζ2 of the portion of the adapter body 30 adjacent to the jig engagement portion 51 in the axial direction and the outer diameter η of the portion of the hose side connection portion 21 adjacent to the jig engagement portion 51 in the axial direction, so that the jig engagement portion 51 cannot be engaged with and operated from the outside unless a dedicated jig 70 is provided. This effectively prevents the hose 20 from being removed from the adapter body 31, and further enhances the anti-theft effect.

[0059] According to the water-discharging device theft prevention adapter 30 of this embodiment, the adapter body 31 has a large diameter portion 32 on the water-discharging device side connection portion 12 side and a small diameter portion 33 on the hose side connection portion 21 side, the inner periphery of the large diameter portion 32 and the outer periphery of the water-discharging device connection joint 40 face each other and are rotatable relative to each other in the circumferential direction, the outer periphery of the small diameter portion 33 and the inner periphery of the hose connection joint 50 face each other and are rotatable relative to each other in the circumferential direction, and the jig engagement portion 41 of the water-discharging device connection joint 40 engages with the hose in the water-discharging device connection joint 40. Since the jig engagement portion 41, 51 of the hose connection fitting 50 is provided at the opposite end (upper part of the drawing) of the water-discharging device side connection portion 21, and the jig engagement portion 51 of the hose connection fitting 50 is provided at the end (upper part of the drawing) of the water-discharging device side connection portion 12 of the hose connection fitting 50, the water-discharging device 10 cannot be removed from the adapter body 31 and the hose 20 cannot be removed from the adapter body 31 unless the jig engagement portions 41, 51 are engaged and operated with a special tool 70, this more reliably prevents the theft of the water-discharging device.

[0060] When the shower head 10 and the hose 20 are attached to the water-discharging appliance anti-theft adapter 30, the water-discharging appliance anti-theft adapter 30 rotates freely when an external force in the rotational direction is applied, and thus the water-discharging appliance anti-theft adapter 30 has an anti-theft effect. When screwing the male thread 13 of the water-discharging appliance side connection part 12 into the female thread 42 of the water-discharging appliance connection joint 40 or releasing said screwing, when screwing the female thread 23 of the hose side connection part 21 into the male thread 52 of the hose side connection joint 50 or releasing said screwing, such screwing / unscrewing operations can be performed only when a jig 70 of a specific shape is used.

[0061] When the water-discharging device anti-theft adapter 30 is attached to the shower head 10 and the hose 20, the appearance is as shown in Figures 1 and 2, where the water-discharging device side jig engagement portion 41 and the hose side jig engagement portion 51 have smaller diameter dimensions (γ, δ) than the other portions of the water-discharging device anti-theft adapter 30 over a small range of β1 and β2, but the outer peripheral shape is a shape in which straight portions 41a and curved portions 41b are repeated alternately, for example, straight portions 41a and arc portions 41b are repeated alternately five times in the circumferential direction, and the external shape is almost close to the same circumferential shape as the other portions, and is integrated with the external diameter design of the shower head 10 and the hose 20, making it excellent in terms of design. Furthermore, the fact that the water-discharging device side jig engaging portion 41 and the hose side jig engaging portion 51 are slightly smaller in diameter is easily considered as part of the design, and there is no sense of incongruity when using the adapter 30 for preventing the theft of a water-discharging device, and since the showerhead 10 can be rotated by the user when using the adapter 30 for preventing the theft of a water-discharging device, it is easy to adjust the direction of the shower and the twist of the hose. Furthermore, in terms of both the circular design and the function such as the rotation function, the adapter 30 for preventing the theft of a water-discharging device is integrated with the showerhead 10 and the hose 20, so that it is difficult to think of removing the showerhead 10 by operating the water-discharging device side jig engaging portion 41 and the hose side jig engaging portion 51, which also contributes to theft prevention. Moreover, the structure of the adapter 30 for preventing the theft of a water-discharging device is such that it cannot be operated with general tools other than the jig 70 of the specific shape shown in FIG. 5.

[0062] According to the adapter 30 for preventing theft of a water-discharging appliance of this embodiment, a water-discharging appliance side anti-slip member 47 is provided between the inner periphery of the large diameter portion 32 and the outer periphery of the water-discharging appliance connection joint 40, and the water-discharging appliance side anti-slip member 47 has a gap adjustment function between the inner periphery of the large diameter portion 32 and the outer periphery of the water-discharging appliance connection joint 40. Therefore, with the simple structure of providing the water-discharging appliance side anti-slip member 47, a synergistic effect is achieved between the effect of preventing the water-discharging appliance connection joint 40 from being dislodged from the adapter main body 31 and the gap adjustment effect between the adapter main body 31 and the water-discharging appliance connection joint 40. In addition, a hose side anti-slip member 57 is provided between the outer periphery of the small diameter portion 33 and the inner periphery of the hose connection fitting 50, and the hose side anti-slip member 57 has a gap adjustment function between the outer periphery of the small diameter portion 33 and the inner periphery of the hose connection fitting 50.Therefore, the simple structure of providing the hose side anti-slip member 57 achieves a synergistic effect of preventing the hose connection fitting 50 from falling out of the adapter main body 31 and of adjusting the gap between the adapter main body 31 and the hose connection fitting 50.

[0063] According to the water-discharging appliance theft prevention adapter 30 of this embodiment, the water-discharging appliance side seal member 48 is provided between the inner periphery of the large diameter portion 32 and the outer periphery of the water-discharging appliance connecting joint 40, and the hose side seal member 58 is provided between the outer periphery of the small diameter portion 33 and the inner periphery of the hose connecting joint 50. In addition, since no special specifications are required for the seal members 48, 58, for example, a commercially available O-ring can be used, and there is a high degree of freedom in selecting the seal members.

[0064] The water-discharging device anti-theft adapter 30 of this embodiment is composed of an adapter body 31, a water-discharging device connection joint 40, and a hose connection joint 50. The basic structure is that the water-discharging device connection joint 40 has a female thread 42 for connecting the shower head 10, and a water-discharging device side seal member 48 made of, for example, an O-ring is attached to the water-discharging device connection joint 40, and then inserted into the adapter body 31 to form a temporary assembly. At this time, the water-discharging device side retaining member 47 acts to prevent the water-discharging device from coming off, and at the same time, since there is an appropriate distance between the adapter body 31 and the water-discharging device connection joint 40, a freely rotatable state can be maintained. Next, a hose side seal member 58 made of, for example, an O-ring is attached to this temporary assembly, and then inserted into the hose connection joint 50 having a male thread 52 for connecting to the hose 20, to complete the water-discharging device anti-theft adapter 30. At this time, the water-discharging device side retaining member 57 acts to prevent the water-discharging device from coming off, and at the same time, since there is an appropriate distance between the adapter body 31 and the hose connection joint 50, a freely rotatable state can be maintained.

[0065] At this time, the water-discharging device side retaining member 47 and the hose side retaining member 57 can secure radial clearance for preventing the water-discharging device from falling out and for allowing the water-discharging device to rotate freely. In addition, standard O-rings made of general synthetic rubber can be used as the water-discharging device side seal member 48 and the hose side seal member 58, which saves the trouble of manufacturing dedicated seal packings. In addition, the O-ring 14 used when screwing various shower heads 10 into the water-discharging device anti-theft adapter 30 of this embodiment and the O-ring 24 used when screwing the water-discharging device anti-theft adapter 30 into the existing hose 20 can both be inexpensive standard O-rings of several different diameters (wall thicknesses), and it is desirable to prepare them in advance as accessories.

[0066] [Second embodiment] A water-discharging tool anti-theft adapter according to a second embodiment of the present invention will be described with reference to Fig. 8. The same components as those in Figs. 1 to 7 are designated by the same reference numerals, and the description thereof will be omitted. Fig. 8 is an enlarged cross-sectional view of the water-discharging tool anti-theft adapter according to the second embodiment.

[0067] An outer contact surface 27 that comes into contact with the O-ring 24 on the hose 20 side is provided on the upper inside of the hose side connection part 21. The space between the outer contact surface 27 and a lower inner corner of the hose side jig engagement part 51 of the hose connection joint 50 forms the seal member arrangement part 25. The outer contact surface 27 is a tapered surface that widens as it goes upward, that is, is inclined at an angle of θ1 with respect to the perpendicular line. The female thread 23 of the hose side connection part 21 and the male thread 52 of the hose connection joint 50 are provided below the seal member arrangement part 25, but since the outer contact surface 27 is a tapered surface, an upward force is applied to the O-ring 24. Here, in the female thread 23 and the male thread 52, the portion less than one revolution from the upper thread machining start position to the complete thread is called an incomplete thread portion and has a sharp tip, and the O-ring 24 is free to move up and down when the tightening starts, and if the O-ring 24 is tightened while in contact with the sharp tip of the incomplete thread portion, it may break. In this embodiment, by providing the outer contact surface 27 with a tapered surface with an angle θ1, an upward force acts on the O-ring 24 to separate it from the sharp tip of the incomplete thread portion. Therefore, according to the water-discharging device anti-theft adapter of this embodiment, by providing a tapered surface on the outer contact surface 27, a force acts on the seal member such as the O-ring 24 in the seal member arrangement portion 25 in a direction away from the male thread 52 of the hose connection joint 50 or the female thread 23 on the inside of the hose side connection portion 21, i.e., in the direction of the water-discharging device side connection portion 12, thereby preventing the O-ring 24 as the seal member from coming into contact with the male thread 52 or the female thread 23 and breaking. Also, by providing a taper on the outer periphery of the seal member arrangement portion 25 of the hose connection joint 50 that becomes smaller in diameter closer to the water-discharging device side connection portion 12 side (upward), it is possible to prevent the O-ring 24 as the seal member from coming into contact with the male thread 52 or the female thread 23 and breaking, similarly to the above case. Furthermore, the tapered surface can be provided in either one or both of the above ways, which increases the freedom in designing the water-discharging device anti-theft adapter to prevent the O-ring 24 as a sealing member from coming into contact with the male thread 52 or the female thread 23 and breaking.

[0068] [Third embodiment] A water-discharging tool anti-theft adapter 30 according to a third embodiment of the present invention will be described with reference to Fig. 9. The same components as those in Figs. 1 to 8 are given the same reference numerals, and descriptions thereof will be omitted. Fig. 9 is an enlarged cross-sectional view of the water-discharging tool anti-theft adapter 30 according to the third embodiment.

[0069] An inner contact surface 59 is provided on the lower inside of the hose side jig engagement portion 51 of the hose connection coupling 50. The space between the inner contact surface 59 and the outer contact surface 27 serves as the seal member arrangement portion 25. The inner contact surface 59 is a tapered surface that becomes smaller in diameter as it goes upward, that is, is inclined at an angle of θ2 with respect to the perpendicular line.

[0070] The water discharger theft prevention adapter 30 of this embodiment needs to be easily and reliably assembled into products that account for a large share of the general distribution volume of existing shower hose assemblies. Here, we will explain the representative shower hose assemblies of companies T and L. Figure 9 is an assembly diagram of the shower hose assembly made by company L and the water discharger theft prevention adapter 30 of this embodiment. The outer contact surface 27 provided on the upper inside of the hose side connection part 21 is perpendicular to the upper end surface 28, and the distance X to the incomplete thread part of the female thread 23 is, for example, about 2 mm, and many of them are distributed. In this case, the part less than one revolution from the thread processing start position to the complete thread is called the incomplete thread part and has a sharp tip. If the inner contact surface 59 provided on the upper outer periphery of the hose connection joint 50 was also perpendicular to the upper end surface 28, the O-ring 24 would be in a position free to move up and down at the start of tightening, and if it were to be tightened while in contact with the sharp tip of this incomplete thread part, it would break. Therefore, in the water-discharge equipment anti-theft adapter 30 of this embodiment, the inner contact surface 59 is provided with an angle θ2 so that an upward force acts on the O-ring 24 trying to separate from the sharp tip of the incomplete thread portion, thereby preventing the O-ring 24 from breaking.

[0071] At the same time, by providing a tapered surface at an angle θ2 on the inner contact surface 59, the upward force acting on the O-ring 24 is perpendicular to the direction of the force acting to loosen the water-discharging device anti-theft adapter 30 of this embodiment, and is therefore in the same direction as the reaction force intended to prevent the spring washer from loosening, so the O-ring 24 itself acts to prevent loosening. On the other hand, in the shower hose assembly manufactured by T, the outer contact surface 27 is angled in advance so that it is wider at the upper side, which is the screw-in entrance side, and narrows toward the lower side, and the space of the seal member arrangement portion 25 is also large, so if the angle θ2 of the tapered surface of the inner contact surface 59 of the hose connection joint 50 is made too large, it will be necessary to increase the thickness of the O-ring 24 in the diametrical direction, and there is a risk that a standard O-ring 24 will not be usable. The shape of hose connection fitting 50 is preferably common regardless of shower hose manufacturer, so it is not particularly limited, but the angle θ2 of the tapered surface of the inner contact surface 59 is set, for example, to be greater than or equal to 3° and less than or equal to 10°.

[0072] [Fourth embodiment] A water-discharging device anti-theft adapter 30 according to a fourth embodiment of the present invention will be described with reference to Fig. 10. The same components as those in Figs. 1 to 9 are given the same reference numerals, and descriptions thereof will be omitted. Fig. 10 is a schematic diagram of a jig 70 for a water-discharging device anti-theft adapter 30 according to the fourth embodiment, and shows three modified examples of the jig 70 in Fig. 5 described in the first embodiment.

[0073] 10A shows a jig 70A as modified example 1. The jig 70A includes a first engagement claw portion 72, a second engagement claw portion 73, and a base portion 74. A first engagement surface 72a which is the inner surface of the first engagement claw portion 72 engages with the first straight portion 41a, a second engagement surface 73a which is the inner surface of the second engagement claw portion 73 engages with the second straight portion 41a, and a third engagement surface 74a of the base portion 74 engages with the third straight portion 41a sandwiched between the first straight portion and the second straight portion. In this way, the jig 70A engages with three adjacent straight lines on the outer periphery of the water-spraying equipment side jig engagement portion 41 through the three engagement surfaces, the first engagement surface 72a, the second engagement surface 73a, and the third engagement surface 74a, thereby more stably engaging with the outer periphery of the water-spraying equipment side jig engagement portion 41. Therefore, the jig 70A is less likely to spin freely on the outer periphery of the water-spraying equipment side jig engagement portion 41, making it easier to operate the water-spraying equipment side jig engagement portion 41.

[0074] FIG. 10B shows a jig 70B as a second modification. The jig 70B has a pair of engagement claws on each end of the operating portion 71. The engagement claws on one side are a first engagement claw portion 72 and a second engagement claw portion 73 similar to the example of FIG. 5. The engagement claws on the other side are a first engagement claw portion 75, a second engagement claw portion 76, and a base portion 77 similar to FIG. 10A. As in FIG. 10A, a first engagement surface 75a which is an inner surface of the first engagement claw portion 75 engages with the first straight portion 41a, a second engagement surface 76a which is an inner surface of the second engagement claw portion 76 engages with the second straight portion 41a, and a third engagement surface 77a of the base portion 77 engages with the third straight portion 41a sandwiched between the first straight portion and the second straight portion. Therefore, the other engaging claw engages with the three adjacent straight line portions on the outer periphery of the water-discharging device side jig engaging portion 41 by the three engaging surfaces, the first engaging surface 75a, the second engaging surface 76a, and the third engaging surface 77a, and thus engages more stably with the outer periphery of the water-discharging device side jig engaging portion 41, so that the jig 70A is less likely to spin around the outer periphery of the water-discharging device side jig engaging portion 41, and the water-discharging device side jig engaging portion 41 is easier to operate. In contrast, the engaging claw on one side can operate the water-discharging device side jig engaging portion 41 by engaging with two surfaces, that is, the first engaging surface 72a, which is the inner surface of the first engaging claw portion 72, engages with one straight line portion 41a, and the second engaging surface 73a, which is the inner surface of the second engaging claw portion 73, engages with the other straight line portion 41a. In the case of this two-surface engagement, there is an advantage that the water-discharging device side jig engaging portion 41 can be commonly operated as long as it is a similar shape, even if the sizes are different.

[0075] The jig 70B of the modified example 2 can operate the water-discharging device side jig engagement part 41 of different sizes when the engagement claws on one side are used, and when the engagement claws on the other side are used, the three engagement surfaces engage with three adjacent straight lines on the outer periphery of the water-discharging device side jig engagement part 41 in the same manner as the jig 70A of the modified example 1, so that the jig 70A is less likely to spin freely on the outer periphery of the water-discharging device side jig engagement part 41, thereby providing a synergistic effect that makes it easier to operate the water-discharging device side jig engagement part 41. Note that even when the engagement claws on the other side are used, the angle formed by the first engagement surface 72a and the second engagement surface 73a is the same, so that it is possible to commonly operate the water-discharging device side jig engagement part 41 with a larger outer periphery.

[0076] 10C shows a jig 70C as a third modified example. The jig 70C has a first engagement claw portion 72 and a second engagement claw portion 73, and an engagement adjustment member 78 is provided as a three-eyed engagement portion on the tip side of the first engagement claw portion 72 and the second engagement claw portion 73 across the tips of both engagement claws. Long holes 72b, 73b are provided on the tips of the first engagement claw portion 72 and the second engagement claw portion 73, respectively, and the engagement position of the engagement adjustment member 78 can be adjustably fixed within the range of the length of the long holes 72b, 73b by engaging the long hole engagement portions provided on both ends of the engagement adjustment member 78 with the long holes 72b, 73b. In the jig 70C of the third modified example, the first engagement surface 75a which is the inner surface of the first engagement claw portion 75 engages with the first straight portion 41a, the second engagement surface 76a which is the inner surface of the second engagement claw portion 76 engages with the second straight portion 41a, and the engagement adjustment member 78 engages with the outer periphery of the water-discharging apparatus side jig engagement portion 41 from the side opposite the first straight portion 41a and the second engagement claw portion 76. Thus, by engaging three adjacent points on the outer periphery of the water-discharging apparatus side jig engagement portion 41 through three engagement points, the jig 70C is less likely to spin freely on the outer periphery of the water-discharging apparatus side jig engagement portion 41, making it easier to operate the water-discharging apparatus side jig engagement portion 41. Furthermore, since the engagement position of the engagement adjustment member 78 can be adjusted and fixed within the range of the longitudinal dimension of the long holes 72b and 73b, it can be commonly operated for water-discharging device side jig engagement parts 41 of different sizes, and since it is engaged at three points, stable engagement can be obtained, and a synergistic effect is achieved in that the jig 70C is less likely to spin freely on the outer periphery of the water-discharging device side jig engagement part 41. Furthermore, the engagement adjustment member 78 can be structured to be detachable from the first engagement claw part 72 and the second engagement claw part 73, and in this case, the operation of engaging the jig 70C with the outer periphery of the water-discharging device side jig engagement part 41 becomes easier. The means for fixing the engagement adjustment member 78 to the first engagement claw part 72 and the second engagement claw part 73 is not particularly limited, but for example, screws can be used. In addition, by providing a member, such as a screw member, that can adjust the position at which the engagement adjustment member 78 engages with the outer periphery of the water-discharging device side jig engagement portion 41, it is possible to make it easier to adjust the engagement position of the engagement adjustment member 78 with the water-discharging device side jig engagement portion 41.

[0077] [Fifth embodiment] A water-discharging tool anti-theft adapter 30 according to a fifth embodiment of the present invention will be described with reference to Fig. 11. The same components as those in Figs. 1 to 10 are given the same reference numerals, and descriptions thereof will be omitted. Fig. 11 is a schematic diagram of a plurality of patterns of arrangement of the jig engagement parts 41, 51 of the water-discharging tool anti-theft adapter 30 according to the fifth embodiment.

[0078] 11A shows a first arrangement pattern similar to that of the first embodiment, in which the jig engagement portion 41 of the water-discharging device connection joint 40 is provided at the end of the water-discharging device connection joint 40 opposite to the hose side connection portion 21 (upper part of the drawing), and the jig engagement portion 51 of the hose connection joint 50 is provided at the end of the hose connection joint 50 on the water-discharging device side connection portion 12 side (upper part of the drawing). A female thread is formed on the inner periphery of the water-discharging device connection joint 40, and is screwed into the male thread of the water-discharging device side connection portion 12. A male thread is formed on the outer periphery of the hose connection joint 50, and is screwed into the female thread of the hose side connection portion 21. The inner periphery of the large diameter portion 32 at the top of the adapter body 31 and the outer periphery of the water-discharging device connection joint 40 are rotatable in the circumferential direction, and the outer periphery of the small diameter portion 33 at the bottom of the adapter body 31 and the inner periphery of the hose connection joint 50 are rotatable in the circumferential direction. Because the adapter body 31 can rotate circumferentially in this manner, the water-discharging device anti-theft adapter 30 has an anti-theft function because the water-discharging device 10 and the hose 20 cannot be removed unless a specific jig 70 is used.

[0079] FIG. 11B shows a second arrangement pattern in which the jig engagement portion 41 of the water-discharging device connection joint 40 is provided at the end of the water-discharging device connection joint 40 opposite the hose side connection portion 21 (upper side of the drawing), and the jig engagement portion 51 of the hose connection joint 50 is provided at the end of the hose connection joint 50 opposite the water-discharging device side connection portion 12 (lower side of the drawing). A female thread is formed on the inner periphery of the water-discharging device connection joint 40, which screws into the male thread of the water-discharging device side connection portion 12. A female thread is formed on the inner periphery of the hose connection joint 50, which screws into the male thread of the hose side connection portion 21. The upper inner periphery of the adapter body 31 and the outer periphery of the water-discharging device connection joint 40 are rotatable in the circumferential direction, and the lower inner periphery of the adapter body 31 and the outer periphery of the hose connection joint 50 are rotatable in the circumferential direction. Because the adapter body 31 can rotate circumferentially in this manner, the water-discharging device anti-theft adapter 30 has an anti-theft function because the water-discharging device 10 and the hose 20 cannot be removed unless a specific jig 70 is used.

[0080] FIG. 11C shows a third arrangement pattern in which the jig engagement portion 41 of the water-discharging device connection joint 40 is provided at the end of the water-discharging device connection joint 40 on the hose-side connection part side (lower side of the drawing), and the jig engagement portion 51 of the hose connection joint 50 is provided at the end of the hose connection joint 50 opposite the water-discharging device side connection part 12 side (lower side of the drawing). A male thread is formed on the outer periphery of the water-discharging device connection joint 40, which screws into the female thread of the water-discharging device side connection part 12. A female thread is formed on the inner periphery of the hose connection joint 50, which screws into the male thread of the hose-side connection part 21. The upper outer periphery of the adapter body 31 and the inner periphery of the water-discharging device connection joint 40 are rotatable in the circumferential direction, and the lower inner periphery of the adapter body 31 and the outer periphery of the hose connection joint 50 are rotatable in the circumferential direction. Because the adapter body 31 can rotate circumferentially in this manner, the water-discharging device anti-theft adapter 30 has an anti-theft function because the water-discharging device 10 and the hose 20 cannot be removed unless a specific jig 70 is used.

[0081] 11D shows a fourth arrangement pattern in which the jig engagement portion 41 of the water-discharging device connection joint 40 is provided at the end of the water-discharging device connection joint 40 on the hose side connection part 21 side (lower in the drawing), and the jig engagement portion 51 of the hose connection joint 50 is provided at the end of the water-discharging device connection joint 40 on the water-discharging device side connection part 12 side (upper in the drawing). A male thread is formed on the outer periphery of the water-discharging device connection joint 40, which screws into the female thread of the water-discharging device side connection part 12. A male thread is formed on the outer periphery of the hose connection joint 50, which screws into the female thread of the hose side connection part 21. The upper outer periphery of the adapter body 31 and the inner periphery of the water-discharging device connection joint 40 are rotatable in the circumferential direction, and the lower outer periphery of the adapter body 31 and the inner periphery of the hose connection joint 50 are rotatable in the circumferential direction. Because the adapter body 31 can rotate circumferentially in this manner, the water-discharging device anti-theft adapter 30 has an anti-theft function because the water-discharging device 10 and the hose 20 cannot be removed unless a specific jig 70 is used.

[0082] According to the water-discharging device anti-theft adapter of this embodiment, the arrangement pattern of the jig engagement portion can be selected from any of the following (1) to (4).
