Description

[Technical field]

[0001] The disclosed embodiments relate to a remote control device. [Background technology]

[0002] Conventionally, a remote control device is installed in a toilet room to remotely control equipment such as a toilet flushing device that flushes the toilet bowl and a toilet seat device that sprays flushing water onto the user's body to clean the private parts. When a remote control device is installed in a toilet room of a public facility such as a station or a hotel, a technique has been proposed in which the remote control body is fastened to a hanger with a screw to prevent theft (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2014-196606 A Summary of the Invention [Problem to be solved by the invention]

[0004] Incidentally, counters, paper roll holders, etc. are often installed around the remote control device. Therefore, if the remote control body is fastened to the hanger with screws as in the conventional technology, for example, a tool may interfere with the counter when turning the screws, which may reduce the ease of installation and removal of the remote control body.

[0005] Thus, the conventional technology has room for improvement in terms of improving the ease of installation and removal of the remote control body. Note that such improvement in ease of installation and removal is not limited to the remote control device installed in the toilet room as described above, but is also required for remote control devices that remotely control various other devices.

[0006] An object of one aspect of the embodiment is to provide a remote control device that can be easily attached and detached while preventing theft. [Means for solving the problem]

[0007] A remote control device according to one aspect of the embodiment comprises a remote control main body for remotely controlling an appliance, a holding portion which is fixed to a wall surface and which holds the remote control main body in a detachable manner, an engagement portion provided at the bottom of the remote control main body and which engages with the holding portion to fix the remote control main body to the holding portion, and a release portion which releases the engagement between the holding portion and the engagement portion, the release portion being positioned so as to be visible when viewed from below the remote control main body and to be hidden when viewed from the front of the remote control main body.

[0008] This makes it possible to prevent, for example, theft of the remote control body. That is, since the release part that releases the engagement between the holding part and the engagement part is located in a position that is hidden when viewed from the front of the remote control body, in other words, the release part is located in a position that is difficult for a toilet user to see, it is possible to make it difficult for a toilet user to understand how to remove the remote control body from the holding part, thereby making it possible to prevent theft of the remote control body.

[0009] In addition, since the release part is positioned in a position that is visible when viewed from below the remote control body, for example, a worker can easily access the release part from the underside of the remote control body, thereby improving the ease of attachment and removal.

[0010] The release portion is operable to release the engagement between the holding portion and the engagement portion by being operated obliquely from below the remote control body with respect to a horizontal plane.

[0011] As a result, even if, for example, a paper roll holder or counter is installed below the remote control device and the working space is relatively small, the worker can access the release part from diagonally below the remote control body to release the engagement between the holding part and the engagement part, thereby further improving the ease of installation and removal.

[0012] The release portion is operable to move in a direction along the bottom surface of the remote control body, thereby releasing the engagement between the holding portion and the engagement portion.

[0013] As a result, even if, for example, a paper roll holder or the like is installed below the remote control device and the working space is relatively small, the worker can disengage the holding part from the engaging part by operating the release part in a direction along the underside of the remote control body, thereby further improving the ease of attachment and removal.

[0014] The release portion is operable to move in the left-right direction of the remote control body, thereby releasing the engagement between the holding portion and the engagement portion.

[0015] This effectively prevents the remote control body from being stolen. In other words, the remote control body is generally longer in the left-right direction than in the front-back direction. Therefore, by configuring the release part to be operated along the left-right direction of the remote control body, it is easy to ensure the travel distance of the release part until the engagement between the holding part and the engagement part is released, for example. This configuration that ensures and lengthens the travel distance of the release part until the engagement is released is also a configuration in which the engagement between the holding part and the engagement part is difficult to release, and as a result, the remote control body can be effectively prevented from being stolen.

[0016] The release portion is formed along the front-to-rear direction of the remote control body, and is provided with a recess into which a specified tool can be inserted to engage the specified tool, and is characterized in that, with the specified tool engaged in the recess, the release portion can be operated and moved along the left-to-right direction of the remote control body to release the engagement between the holding portion and the engagement portion.

[0017] This effectively prevents the theft of the remote control body. In other words, while the insertion direction of the tool into the recess is the front-rear direction of the remote control body, by making the release part operable along the left-right direction of the remote control body, even if a would-be thief inserts something other than a tool that is relatively weak into the recess, it becomes difficult to operate the release part in the left-right direction, and therefore the theft of the remote control body can be effectively prevented.

[0018] The engaging portion and the releasing portion are formed integrally, thereby making it possible to reduce the number of parts.

[0019] The engaging portion is configured so that a portion that engages with the holding portion is positioned at a position that is hidden when viewed from below the remote control body.

[0020] This makes it difficult to directly operate the engaging portion of the engaging part, for example, and therefore makes it possible to more effectively prevent theft of the remote control body.

[0021] The holding portion is provided with a hook portion including an engaging claw that engages with the engaging portion, and the release portion is provided with a recess formed in the hook portion into which a specified tool can be inserted and into which the specified tool can be engaged, and when the specified tool is engaged in the recess, the hook portion bends horizontally, thereby disengaging the holding portion from the engaging portion.

[0022] This makes it possible to effectively prevent theft of the remote control body with a simple configuration.

[0023] The holding portion and the hook portion are formed integrally, which makes it possible to reduce the number of parts.

[0024] The present invention also provides a hook portion including an engagement claw that engages with the engagement portion and is formed so that the engagement portion with the engagement portion has a curved shape, and a rotation shaft portion supported by the holding portion so as to be rotatable along the vertical direction, and the release portion is provided on the hook portion at a position opposite the engagement claw with respect to the rotation shaft portion, and the release portion is operated from below to above to rotate the hook portion, thereby releasing the engagement between the holding portion and the engagement portion.

[0025] This makes it possible to effectively prevent theft of the remote control body with a simple configuration. Effect of the Invention

[0026] According to one aspect of the embodiment, in a remote control device, it is possible to improve ease of attachment and detachment while preventing theft. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0028] Hereinafter, an embodiment of a remote control device disclosed in the present application will be described in detail with reference to the accompanying drawings. Note that the present invention is not limited to the embodiment described below.

[0029] (First embodiment) FIG. 1 is an overall view showing a toilet system equipped with a remote control device according to a first embodiment. Note that FIG. 1 and the figures shown in FIG. 2 and thereafter are all schematic views. Therefore, the size and shape of each component shown in FIG. 1 and the like are not necessarily accurate. Also, in each drawing, for the sake of ease of understanding, some components may be omitted or exaggerated.

[0030] As shown in FIG. 1, the toilet system 1 includes a toilet device 2 and a remote control device 3.

[0031] The toilet device 2 includes a toilet bowl 5, a toilet bowl flushing device 6, and a toilet seat device 7. The toilet bowl 5 is, for example, a Western-style flush toilet bowl, and is placed in a toilet room R. Note that, although a floor-standing toilet bowl 5 is shown here, the toilet bowl 5 may also be a wall-hung type.

[0032] The toilet flushing device 6 is a device that flushes the toilet 5. For example, the toilet flushing device 6 includes a water passage 6a that supplies flushing water to the toilet 5, and a first main body unit 6b that is connected to the water passage 6a. For example, the first main body unit 6b can flush the toilet 5 by switching between supplying and stopping water from the water passage 6a to the toilet 5 in response to remote control by the remote control device 3.

[0033] The toilet seat device 7 is a sanitary washing device that includes a second main body part 7a installed on the top of the toilet bowl 5 and a toilet seat 7b pivotally supported on the second main body part 7a so as to be freely opened and closed, and has the function of washing the private parts of a user. For example, the second main body part 7a can control a washing nozzle (not shown) in response to remote control by the remote control device 3, and spray washing water onto the user's body to wash the private parts.

[0034] In the above, the toilet seat device 7 is described as having a sanitary washing function, but this is not limited to this. Instead of or in addition to the sanitary washing function, the toilet seat device 7 may have a drying function that blows warm air onto the buttocks of a user sitting on the toilet seat 7b to dry them, or a toilet seat heating function that warms the seating surface of the toilet seat 7b to an appropriate temperature.

[0035] As described above, the remote control device 3 is a device that remotely controls devices such as the toilet flushing device 6 and the toilet seat device 7. In the above, the remote control device 3 remotely controls both the toilet flushing device 6 and the toilet seat device 7, but this is not limited to this, and for example, the remote control device 3 may be configured to control either the toilet flushing device 6 or the toilet seat device 7.

[0036] The remote control device 3 is installed, for example, on a wall surface W of the toilet room R. In the example shown in Fig. 1, the remote control device 3 is installed on the wall surface W on the left side as seen from a user sitting on the toilet seat 7b, but the installation position is not limited to this.

[0037] In addition, in the toilet room R, a counter C is installed below the remote control device 3. In the example of Fig. 1, the counter C is installed below the remote control device 3, but this is not limited to this, and other types of accessories such as a paper roll holder may be installed. Also, the configuration may not include the counter C or the paper roll holder installed below the remote control device 3.

[0038] For ease of explanation, Fig. 1 illustrates a three-dimensional Cartesian coordinate system that defines mutually orthogonal X-axis, Y-axis, and Z-axis directions and defines the positive Z-axis direction as the vertically upward direction. This Cartesian coordinate system may also be shown in other drawings used in the following explanation.

[0039] In addition, in the following description of remote control device 3, for example, based on the state when installed on wall W, the positive X-axis direction in the Cartesian coordinate system may be described as "right," the negative X-axis direction as "left," the positive Y-axis direction as "forward" or "front," the negative Y-axis direction as "rear," the positive Z-axis direction as "upward," and the negative Z-axis direction as "downward."

[0040] Meanwhile, the remote control device 3 may be installed in a restroom R in a public facility used by many people, such as a train station or a hotel. In such a case, in the prior art, the remote control body is fastened with a screw to a holder (hanger) not shown in FIG. 1 to prevent theft.

[0041] However, a counter C and the like are installed around (more specifically, below) the remote control device 3. Therefore, if the remote control device 3 is fastened with a screw as described above, for example, a tool may interfere with the counter C when turning the screw, which may reduce ease of installation and removal of the remote control body.

[0042] Therefore, the remote control device 3 according to this embodiment is configured to improve ease of installation and removal while preventing theft. This configuration will be described in detail below with reference to FIG. 2 and subsequent figures.

[0043] Fig. 2 is a front view of the remote control device 3. Fig. 3 is a rear view of the remote control device 3, and Fig. 4 is a bottom view of the remote control device 3. Fig. 5 is an exploded perspective view of the remote control device 3.

[0044] As shown in FIGS. 2 to 5, the remote control device 3 includes a remote control body 10, a holding portion 20, an engagement member 30, and a release member .

[0045] The remote control body 10 includes a base portion 11 and a case portion 12, and remotely controls devices such as the toilet flushing device 6 and the toilet seat device 7.

[0046] The case portion 12 is provided with operation buttons 13, which are operated by the user. For example, the operation buttons 13 include a toilet flushing button and a private parts cleaning button, and a drive signal is output to the toilet flushing device 6 and the toilet seat device 7 in response to the button operated by the user, and the toilet flushing, private parts cleaning, etc. are performed. The arrangement and shape of the operation buttons 13 are not limited to the example shown in FIG. 2 etc. The case portion 12 described above is attached to the base portion 11.

[0047] A control board (not shown) and the like are disposed and fixed on the base portion 11 and are appropriately accommodated in the space between the base portion 11 and the case portion 12 .

[0048] As shown in FIG. 5, the base portion 11 is formed, for example, in a plate shape, and includes a mounting portion 14 and a spring accommodating portion 15. As shown in FIG.

[0049] The placement portion 14 is a portion that is placed on a base portion 22 (described later) of the holding portion 20 when the remote control main body 10 is held by the holding portion 20 (see FIG. 7 described later). For example, the placement portion 14 is a plate-shaped portion formed on the left and right sides near the lower portion of the base portion 11. The placement portion 14 is formed so as to protrude forward from the base body of the base portion 11.

[0050] The spring accommodating portion 15 is a portion that accommodates a spring 50 (see FIG. 7 described later). The spring 50 is used when the engaging portion 31 of the engaging member 30 engages with the holding portion 20, which will be described later. For example, the spring accommodating portion 15 is a rectangular portion formed in the center near the lower portion of the base portion 11.

[0051] The holding part 20 is a member (hanger) that detachably holds the remote control body 10. As shown in Fig. 5, the holding part 20 is formed, for example, in a rectangular shape when viewed from the front and in a thin plate shape. Note that the surface of the holding part 20 that is disposed opposite the back surface 11a of the remote control body 10 and that holds the remote control body 10 (the surface on the Y-axis positive direction side) may be referred to as the "holding surface 20a."

[0052] The holding portion 20 includes a screw insertion hole 21 and a base portion 22. A plurality of (for example, two) screw insertion holes 21 are formed at appropriate positions of the holding portion 20. Screws (not shown) are inserted into the screw insertion holes 21 from the positive side of the Y axis toward the negative direction, thereby fixing the holding portion 20 to the wall surface W (see FIG. 1). Note that the positions and number of the screw insertion holes 21 are not limited to the example shown in the figure.

[0053] The base portion 22 is formed in the holding portion 20 at a position corresponding to the placement portion 14 of the remote control body 10. Specifically, the base portion 22 is a plate-shaped portion formed on the left and right sides near the lower portion of the holding portion 20. The base portion 22 is formed so as to protrude forward from the holding surface 20a of the holding portion 20.

[0054] The remote control body 10 is attached from above to the holding portion 20 and held therein, and in the held state, the placement portion 14 is placed on the base portion 22 as described above.

[0055] The engagement member 30 is a member that can engage with the holding portion 20. As shown in Fig. 3 and Fig. 4, the engagement member 30 includes an engagement portion 31, and the engagement portion 31 engages with the holding portion 20 to fix the remote control main body 10 to the holding portion 20. Note that a detailed configuration of the engagement member 30 including the engagement portion 31 will be described later with reference to Fig. 6 etc.

[0056] The release member 40 is a member that can release the engagement between the holding portion 20 and the engaging portion 31. As shown in Fig. 4, the release member 40 includes a release portion 41, and the release portion 41 can be operated by an operator to release the engagement between the holding portion 20 and the engaging portion 31. The detailed configuration of the release member 40 that includes the release portion 41 will be described later with reference to Fig. 6 etc.

[0057] Here, the position where the release part 41 is arranged on the remote control body 10 will be described with reference to Fig. 4 and Fig. 2. First, as shown in Fig. 4, an opening 12b is formed on the lower surface 12a of the case part 12. The opening 12b is, for example, an elongated slit, and is formed along the front-rear direction (Y-axis direction) of the remote control body 10.

[0058] The release unit 41 is accommodated in the case 12 and disposed at a position corresponding to the opening 12b of the case 12, more specifically, at a position visible from the opening 12b. That is, the release unit 41 is disposed at a position visible when viewed from the bottom of the remote control body 10. On the other hand, as shown in Fig. 2, the release unit 41 is accommodated in the case 12 without protruding from the bottom surface 10a of the remote control body 10, and is therefore disposed at a position hidden when viewed from the front of the remote control body 10.

[0059] In this way, the release part 41 is positioned in a hidden position when viewed from the front of the remote control body 10, and is positioned in a position that is difficult to see for toilet users, so that it is difficult to understand how to remove the remote control body 10 from the holding part 20, thereby preventing theft of the remote control body 10.

[0060] Furthermore, since the release portion 41 is positioned in a position that is visible when viewed from below the remote control body 10, for example, an operator can easily access the release portion 41 from the underside of the remote control body 10, thereby improving the ease of installation and removal.

[0061] Next, the remote control device 3 will be described in more detail with reference to Fig. 6 and subsequent figures. Fig. 6 is a partially enlarged perspective view showing an enlarged view of the lower part of the remote control device 3, and Fig. 7 is a partially enlarged front view showing an enlarged view of the lower part of the remote control device 3. For ease of understanding, Figs. 6 and 7 show a state in which the case 12 has been removed.

[0062] 6 and 7, the engagement member 30 includes the above-mentioned engagement portion 31, the connecting portion 32, and the pressing portion 33, and is provided at the bottom of the remote control body 10. The engagement member 30 is arranged so as to be movable along the left-right direction (X-axis direction) within the remote control body 10. The engagement portion 31, the connecting portion 32, and the pressing portion 33 are integrally formed.

[0063] The engagement portion 31 is located on the left side (negative direction of the X-axis) of the engagement member 30. The engagement portion 31 includes an engagement claw 31a and an abutment surface 31b. The engagement claw 31a can sandwich the pedestal portion 22 of the holding portion 20 between the mounting portion 14 of the base portion 11. This allows the engagement portion 31 including the engagement claw 31a to engage with the holding portion 20, and fixes the remote control body 10 to the holding portion 20.

[0064] The contact surface 31b is a surface that comes into contact with the base part 22 of the holding part 20 when the remote control main body 10 is attached to the holding part 20. The contact surface 31b is formed so as to be inclined about the Y axis with respect to the horizontal plane (XY plane), more specifically, the inclination is upward to the left, and the inclination is formed so as to approach the base part 22 located on the left as it goes upward when viewed from the front.

[0065] The connecting portion 32 is located to the right (positive direction of the X-axis) of the engaging portion 31, and connects the engaging portion 31 and the pressing portion 33. In addition, the connecting portion 32 is formed so as to provide a space between the engaging portion 31 and the pressing portion 33 for the release member 40 to fit therein.

[0066] The pressing portion 33 is located on the right side (positive direction of the X-axis) of the engaging member 30. Here, the spring accommodating portion 15 of the base portion 11 is provided to the right of the pressing portion 33. The spring accommodating portion 15 accommodates the spring 50 as described above.

[0067] The spring 50 has an end that abuts against the pressing portion 33, and biases the pressing portion 33 to the left (the negative direction of the X-axis). A coil spring can be used as the spring 50, but is not limited thereto, and other types of elastic members such as leaf springs and disc springs may be used as long as they are elastically deformable to generate a biasing force.

[0068] The pressing portion 33 moves to the right and presses the spring 50 against the spring force of the spring 50, for example, when the remote control main body 10 is attached to the holding portion 20 or when the release member 40 described later is operated by an operator.

[0069] Here, the attachment of the remote control body 10 to the holder 20 will be described with reference to Fig. 8. Fig. 8 is a diagram for explaining the attachment of the remote control body 10 to the holder 20.

[0070] As shown by the arrow D1 in Fig. 8, the remote control body 10 is attached to the holding part 20 from above. To explain in detail, the remote control body 10 is first arranged so that the placement part 14 is located above the base part 22 of the holding part 20. At this time, the engaging member 30 including the pressing part 33 is biased leftward by the spring 50, so that the engaging part 31 on the left side of the engaging member 30 is positioned between the placement part 14 and the base part 22.

[0071] Then, when the remote control body 10 is moved downward by the operator, the base portion 22 comes into contact with the abutment surface 31b of the engagement portion 31. When the remote control body 10 is further moved downward, the base portion 22 slides on the inclined abutment surface 31b and gradually pushes it to the right, as shown by the imaginary line (see arrow D2). This pushing causes the engagement member 30 to move to the right, and the pressing portion 33 presses the spring 50.

[0072] Furthermore, when the remote control body 10 is moved downward, the base portion 22 passes over the contact surface 31b and no longer presses the contact surface 31b to the right. As a result, the engaging member 30 moves to the left due to the leftward biasing force caused by the elastic deformation of the spring 50, and the engaging claw 31a of the engaging portion 31 can clamp the base portion 22 between it and the placement portion 14 (see FIG. 7). This allows the engaging portion 31 to engage with the holding portion 20, and the remote control body 10 is fixed to the holding portion 20.

[0073] 8, a protrusion 14a protruding downward is formed on the mounting portion 14. An insertion hole 22a through which the protrusion 14a can be inserted is formed on the base portion 22 at a position corresponding to the protrusion 14a, as shown in FIGS.

[0074] Therefore, as shown in FIGS. 6 and 7, when the placement portion 14 is placed on the base portion 22, in other words, when the remote control body 10 is held by the holding portion 20, the protrusion portion 14a is inserted into the insertion hole 22a.

[0075] As a result, even if the remote control body 10 is pulled toward the user (positive Y-axis direction) by an would-be thief, the remote control body 10 is less likely to move relative to the holding portion 20, thereby effectively preventing theft of the remote control body.

[0076] Next, the release member 40 will be described with reference to Figures 6 and 7. The release member 40 includes a release portion 41 and an abutment portion 42, and is provided at the bottom of the remote control body 10. A part or the whole of the release member 40 is disposed in a space formed in the connecting portion 32 of the engagement member 30. The release member 40 is disposed within the remote control body 10 so as to be movable along the up-down direction (Z-axis direction). Furthermore, the release portion 41 and the abutment portion 42 are formed integrally.

[0077] The release portion 41 is located on the lower side (Z-axis negative direction) of the release member 40. For example, the release portion 41 is formed so as to protrude downward from the contact portion 42 and extend along the front-rear direction while having a predetermined width in the left-right direction.

[0078] The contact portion 42 is located above the release portion 41 (positive direction of the Z axis), and at the upper side of the release member 40. The contact portion 42 includes a contact surface 42a.

[0079] The contact surface 42a is formed on the right side of the contact portion 42, in other words, on the pressing portion 33 side, and is a surface that comes into contact with the pressing portion 33. In Fig. 7, the contact position between the contact surface 42a and the pressing portion 33 is indicated by reference symbol B1.

[0080] The contact surface 42a is formed so as to be inclined around the Y-axis with respect to the horizontal plane (XY plane); more specifically, it is inclined downward to the right when viewed from the front, and is formed so as to approach the pressing portion 33 located on the right as it goes downward.

[0081] The release member 40 configured as described above can be operated by an operator to release the engagement between the holding portion 20 and the engagement portion 31 of the engagement member 30. The release operation will be described below with reference to Figs. 9 to 11.

[0082] Fig. 9 is a side view of the remote control device 3 when the release operation is performed, seen from the left side. In Fig. 9, the release portion 41 is indicated by a broken line block for the sake of simplicity. Fig. 10 is a cross-sectional view taken along line XX in Fig. 7, specifically, a side cross-sectional view of the vicinity of the release portion 41. Fig. 11 is a view showing a state in which the engagement between the holding portion 20 and the engagement portion 31 has been released.

[0083] 9, the release operation is performed by operating the release part 41 of the release member 40 from diagonally below the remote control body 10 with respect to the horizontal plane. In detail, the release part 41 is pushed up by a predetermined tool T from diagonally below the front side of the remote control body 10 (see arrow D3).

[0084] At this time, as shown in Fig. 10, the tool T is inserted into the opening 12b formed in the bottom surface 10a of the remote control body 10 to access the bottom surface 41a of the release part 41 and push the release part 41 upward. Note that, as the tool T, for example, a flat-head screwdriver can be used, but is not limited to this.

[0085] 9, a counter C is set below the remote control device 3 according to this embodiment. Therefore, the working space between the remote control device 3 and the counter C tends to be relatively small. Even if the working space is relatively small, the worker can access the release portion 41 from diagonally below the remote control body 10 to release the engagement between the holding portion 20 and the engagement portion 31, thereby further improving the ease of installation and removal.

[0086] 11, when the release portion 41 is pushed upward, the abutment portion 42 is also moved upward. At this time, the abutment portion 42 is moved upward while the abutment position B2 with the pressing portion 33 shifts to the right on the abutment surface 42a of the abutment portion 42, so that the abutment portion 42 presses the pressing portion 33 to the right. Due to this pressing, the engagement member 30 moves to the right against the biasing force of the spring 50 (see arrow D4), and the engagement between the holding portion 20 and the engagement portion 31 is released.

[0087] Although not shown in the drawings, when the engagement between the holding portion 20 and the engagement portion 31 is released, the remote control body 10 can be removed from the holding portion 20 by pulling the remote control body 10 upward.

[0088] As described above, the remote control device 3 according to the first embodiment includes a remote control body 10, a holding part 20, an engaging part 31, and a releasing part 41. The remote control body 10 remotely controls an appliance (for example, a toilet flushing device 6 or a toilet seat device 7). The holding part 20 is fixed to a wall surface W and holds the remote control body in a detachable manner. The engaging part 31 is provided at the bottom of the remote control body 10 and engages with the holding part 20 to fix the remote control body 10 to the holding part 20. The releasing part 41 releases the engagement between the holding part 20 and the engaging part 31. The releasing part 41 is arranged at a position that is visible when viewed from below the remote control body 10 and is hidden when viewed from the front of the remote control body 10. This makes it possible to prevent theft and improve the ease of attachment and detachment.

[0089] Second embodiment Next, a second embodiment will be described. In the following description, the same reference numerals are used for parts that are similar to those already described, and duplicated descriptions will be omitted. In the following description of the second embodiment, the configurations corresponding to those of the first embodiment may be described with a "1" added to the beginning of the reference numeral.

[0090] 12 is a bottom view of the remote control device 3 according to the second embodiment. In the second embodiment, the release part 141 is operated and moved in a direction along the bottom surface 10a of the remote control body 10, more specifically, in the left-right direction (X-axis direction, horizontal direction) of the remote control body 10, thereby enabling the engagement between the holding part 20 and the engagement part 131 to be released.

[0091] First, a description will be given of the position where release section 141 is disposed on remote control body 10. As shown in Fig. 12, opening 112b is formed on bottom surface 112a of case section 112. Opening 112b is, for example, a long slit, and is formed along the left-right direction of remote control body 10.

[0092] Similarly to the first embodiment, the release unit 141 is housed in the case unit 112 and disposed at a position corresponding to the opening 112b of the case unit 112, more specifically, at a position visible from the opening 112b. That is, the release unit 141 is disposed at a position visible when viewed from the bottom of the remote control body 10. On the other hand, in the second embodiment, as shown in FIG. 2, the release unit 141 is housed in the case unit 112 without protruding from the bottom surface 10a of the remote control body 10, and is therefore disposed at a position hidden when viewed from the front of the remote control body 10.

[0093] As a result, in the second embodiment, like the first embodiment, it is possible to prevent the remote control body 10 from being stolen, while improving ease of attachment and detachment.

[0094] Next, the remote control device 3 according to the second embodiment will be described in detail with reference to Fig. 13 and subsequent figures. Fig. 13 is a partially enlarged perspective view showing an enlarged view of the lower portion of the remote control device 3 according to the second embodiment, and Fig. 14 is a partially enlarged front view showing an enlarged view of the lower portion of the remote control device 3 according to the second embodiment. For ease of understanding, Figs. 13 and 14 show a state in which the case part 112 is removed.

[0095] 13 and 14, the engagement member 130 includes an engagement portion 131, a connecting portion 132, and a pressing portion 133, and is arranged to be movable along the left-right direction (X-axis direction) within the remote control body 10. The engagement portion 131 engages with the holding portion 20 by an engagement claw 131a.

[0096] The release member 140 includes a release portion 141 and an abutment portion 142, and is formed, for example, in a plate shape. As described below, the release portion 141 is released from engagement when a right side surface 141a is operated. The abutment portion 142 abuts against the pressing portion 133 at an end portion 142a near the upper right portion. In FIG. 14, the abutment position between the end portion 142a and the pressing portion 133 is indicated by reference symbol B11.

[0097] In the second embodiment, the release member 140 is disposed within the remote control body 10 so as to be rotatable about the front-rear direction (Y-axis direction).

[0098] For example, an insertion hole 143 is formed near the center of the release member 140. A protrusion 116 that protrudes forward (Y-axis positive direction) is formed in the base portion 111 at a position corresponding to the insertion hole 143. By inserting the protrusion 116 into the insertion hole 143, the release member 140 is made rotatable about the protrusion 116, in other words, about the front-rear direction.

[0099] The release member 140 configured as described above can release the engagement between the holding portion 20 and the engagement portion 131 by being operated by an operator.

[0100] Fig. 15 is a side view of the remote control device 3 in which the release operation is performed, as seen from the left side. In Fig. 15, for the sake of simplicity, the release portion 141 is indicated by a broken line block. Fig. 16 is a diagram showing a state in which the engagement between the holding portion 20 and the engagement portion 131 has been released.

[0101] 15, the release operation is performed by operating release portion 141 of release member 140 from diagonally below remote control body 10 with respect to the horizontal plane. More specifically, release portion 141 is operated from diagonally below the side of remote control body 10 with tool T in a direction along undersurface 10a, more specifically, in the left-right direction (to the left, to be precise) of remote control body 10 (see arrow D11).

[0102] At this time, tool T is inserted into opening 112b on the underside 10a of the remote control main body 10 shown in FIG. 12 to access side surface 141a of release portion 141 and slide release portion 141 in the left-right direction (to the left, to be precise).

[0103] As can be seen from FIG. 15, in the second embodiment, as in the first embodiment, counter C is set below the remote control device 3, and even if the working space is relatively small, the worker can access release portion 141 from diagonally below remote control main body 10 to release the engagement between holding portion 20 and engagement portion 131, thereby further improving the ease of installation and removal.

[0104] 16, when the release portion 141 is slid to the left, the release member 140 rotates clockwise in a front view, and the abutment portion 142 pushes the pressing portion 133 to the right with the end portion 142a. By this pushing, the engagement member 130 moves to the right against the biasing force of the spring 50 (see arrow D12), and the engagement between the holding portion 20 and the engagement portion 131 is released.

[0105] In this way, in the second embodiment, the release portion 141 can be operated to move (slide) along the left-right direction of the remote control body 10, thereby releasing the engagement between the holding portion 20 and the engagement portion 131.

[0106] This effectively prevents the remote control body 10 from being stolen. In other words, the remote control body 10 is generally longer in the left-right direction (horizontal direction) than in the front-rear direction. Therefore, by configuring the release part 141 to be operated along the left-right direction of the remote control body, it is easy to ensure the movement distance of the release part 141 until the engagement between the holding part 20 and the engagement part 131 is released, for example. This configuration that ensures and lengthens the movement distance of the release part 141 until the engagement is released is also a configuration in which the engagement between the holding part 20 and the engagement part 131 is difficult to release, and as a result, the remote control body 10 can be effectively prevented from being stolen.

[0107] (Third embodiment) Next, a third embodiment will be described. In the following description of the third embodiment, configurations corresponding to those of the first embodiment may be designated by adding a "2" to the beginning of the reference numeral.

[0108] 17 is a bottom view of the remote control device 3 according to the third embodiment. In the third embodiment, the release part 241 is operated and moved in a direction along the bottom surface 10a of the remote control body 10, more specifically, along the front-rear direction (Y-axis direction) of the remote control body 10, thereby disengaging the holding part 20 from the engagement part 231.

[0109] First, a description will be given of the position at which the release part 241 is disposed in the remote control body 10. As shown in Fig. 17, an opening 212b is formed in the lower surface 212a of the case part 212. The opening 212b is, for example, a long slit, and is formed along the front-rear direction of the remote control body 10.

[0110] Similarly to the first embodiment, the release unit 241 is housed in the case unit 212 and disposed at a position corresponding to the opening 212b of the case unit 212, more specifically, at a position visible from the opening 212b. That is, the release unit 241 is disposed at a position visible when viewed from the bottom of the remote control body 10. On the other hand, in the third embodiment, as shown in FIG. 2, the release unit 241 is housed in the case unit 212 without protruding from the bottom surface 10a of the remote control body 10, and is therefore disposed at a position hidden when viewed from the front of the remote control body 10.

[0111] As a result, in the third embodiment, like the first embodiment, it is possible to prevent the remote control body 10 from being stolen, while improving ease of attachment and detachment.

[0112] As shown in FIG. 17, in the third embodiment, the engagement portion 231 is configured to be disposed in a position where the portion that engages with the holding portion 20 is hidden when the remote control body 10 is viewed from below.

[0113] For example, the case part 212 includes a cover part 213. The cover part 213 is formed on the lower surface 212a of the case part 212 at a position that covers the engaging part of the engaging part 231 with the holding part 20 in a bottom view.

[0114] The above-mentioned cover portion 213 hides the engagement portion of the engagement portion 231 with the holding portion 20 when viewed from below, making it difficult to directly operate the engagement portion of the engagement portion 231 to release the engagement, for example, and as a result, theft of the remote control body 10 can be more effectively prevented.

[0115] The above-described cover portion 213 may be applied to the case portions 12, 112 according to the first and second embodiments.

[0116] Next, the remote control device 3 according to the third embodiment will be described in more detail with reference to Fig. 18 onwards. Fig. 18 is a partially enlarged perspective view showing an enlarged view of the lower part of the remote control device 3 according to the third embodiment, and Fig. 19 is a partially enlarged front view showing an enlarged view of the lower part of the remote control device 3 according to the third embodiment. For ease of understanding, Figs. 18 and 19 show a state in which case 212 has been removed.

[0117] 18 and 19, the engagement member 230 includes an engagement portion 231, a connecting portion 232, and a pressing portion 233, and is arranged to be movable along the left-right direction (X-axis direction) within the remote control body 10. The engagement portion 231 engages with the holding portion 20 by an engagement claw 231a.

[0118] Fig. 20 is a cross-sectional view taken along line XX-XX in Fig. 19. As shown in Fig. 20, the connecting portion 232 is formed on the rear side (Y-axis negative direction side) so as to provide a space S between the engaging portion 231 and the pressing portion 233 into which the release member 240 can be inserted.

[0119] The pressing portion 233 has an abutment surface 233a. The abutment surface 233a is formed on the left side of the pressing portion 233, in other words, on the side of the releasing member 240. The abutment surface 233a is a surface that abuts against the abutment portion 242 of the releasing member 240.

[0120] The contact surface 233a is formed so as to be inclined about the Z axis with respect to a vertical plane (YZ plane) in the front-rear direction, more specifically, so as to be inclined to the left as it goes forward when viewed from below. In Fig. 20 and Fig. 21 described later, the contact position between the contact surface 233a and the contact portion 242 is indicated by the reference symbol B21.

[0121] The release member 240 includes a release portion 241 and a contact portion 242, and is formed, for example, in a plate shape. Fig. 21 is a cross-sectional view taken along line XXI-XXI in Fig. 19, and specifically, is a side cross-sectional view of the vicinity of the release portion 241.

[0122] 21, the release portion 241 is released from engagement when an end 241a near the lower front portion is operated. The abutment portion 242 abuts against the pressing portion 233 (more precisely, the abutment surface 233a) at an end 242a near the upper front portion.

[0123] In the third embodiment, the release member 240 is arranged rotatably about the left-right direction (X-axis direction) within the remote control body 10. In Fig. 21, the rotation axis is indicated by reference symbol E21.

[0124] The release member 240 configured as described above can be operated by an operator to release the engagement between the holding portion 20 and the engagement portion 231. Fig. 22 is a front view showing a state in which the engagement between the holding portion 20 and the engagement portion 231 has been released, and corresponds to Fig. 19. Fig. 23 is a cross-sectional view showing a state in which the engagement between the holding portion 20 and the engagement portion 231 has been released, and corresponds to Fig. 20.

[0125] 21, the release operation is performed by operating release portion 241 of release member 240 from diagonally below remote control body 10 with respect to the horizontal plane. In detail, release portion 241 is operated from diagonally below the front side of remote control body 10 with tool T in a direction along undersurface 10a, more specifically, along the front-rear direction (rear to be precise) of remote control body 10 (see arrow D21).

[0126] At this time, tool T is inserted into opening 212b on the underside 10a of the remote control main body 10 shown in Figure 17, accessing end 241a of release portion 241 and sliding release portion 241 in the front-to-back direction (rearward to be precise).

[0127] Although not shown in the figures, in the third embodiment, even if the working space below the remote control device 3 is reduced by a counter C or the like, the worker can access the release portion 241 from diagonally below the remote control main body 10, thereby disengaging the holding portion 20 from the engagement portion 231, thereby further improving the ease of installation and removal.

[0128] When the release portion 241 is slid rearward, the release member 240 rotates clockwise around the rotation axis E21 when viewed from the left side, and the abutment portion 242 pushes the pressing portion 233 forward with the end portion 242a (see arrow D22 in Figures 21 and 23).

[0129] Here, since the release member 240 including the pressing portion 233 is configured to be movable in the left-right direction (X-axis direction), when pressed from the abutting portion 242, the engagement member 230 moves to the right against the biasing force of the spring 50 (see arrow D23) as shown in Figures 22 and 23. This causes the engagement between the holding portion 20 and the engagement portion 231 to be released.

[0130] In this way, in the third embodiment, the release portion 241 can be operated to move (slide) along the front-rear direction of the remote control body 10, thereby releasing the engagement between the holding portion 20 and the engagement portion 231.

[0131] (Fourth embodiment) Next, a fourth embodiment will be described. In the following description of the fourth embodiment, configurations corresponding to those of the first embodiment may be designated by adding the number "3" to the beginning of the reference numeral.

[0132] Fig. 24 is a front view of the remote control device 3 according to the fourth embodiment. Fig. 25 is a bottom view of the remote control device 3 according to the fourth embodiment, and Fig. 26 is an exploded perspective view of the remote control device 3 according to the fourth embodiment. Note that, as the remote control device 3 according to the fourth embodiment, for example, a remote control device that is relatively long in the left-right direction can be used, but is not limited to this.

[0133] 24 to 26, the remote control device 3 according to the fourth embodiment includes a remote control main body 310, a holding unit 320, and an engagement member 330. The remote control main body 310 includes a base unit 311 and a case unit 312, and the engagement member 330 is provided near the bottom. The base unit 311 includes a placement unit 314 (hidden and not visible; see FIG. 30 described later). The holding unit 320 includes a base unit 322 at a position corresponding to the placement unit 314.

[0134] 25, engaging member 330 according to the fourth embodiment includes a releasing portion 341. That is, in the fourth embodiment, engaging member 330 includes releasing portion 341, and thus has a function of releasing the engagement with holding portion 320 in addition to a function of engaging with holding portion 320. The detailed configuration of engaging member 330 including releasing portion 341 will be described later with reference to FIG. 27 etc.

[0135] Here, the position where the release part 341 is arranged on the remote control body 10 will be described with reference to Fig. 25. As shown in Fig. 25, an opening 312b is formed on the lower surface 312a of the case part 312. The opening 312b is, for example, a long slit, and is formed along the front-rear direction (Y-axis direction) of the remote control body 310.

[0136] The release section 341 is accommodated in the case section 312 and disposed at a position corresponding to the opening 312b of the case section 312, more specifically, at a position visible from the opening 312b. That is, the release section 341 is disposed at a position visible when viewed from the bottom of the remote control body 10. On the other hand, as shown in Fig. 24, the release section 341 is accommodated in the case section 312 without protruding from the bottom surface 310a of the remote control body 310, and is therefore disposed at a position hidden when viewed from the front of the remote control body 310.

[0137] As a result, in the fourth embodiment, like the first embodiment, it is possible to prevent the remote control body 310 from being stolen, while improving ease of attachment and detachment.

[0138] Next, the remote control device 3 will be described in detail with reference to Fig. 27 and subsequent figures. Fig. 27 is a partially enlarged perspective view of the vicinity of an engaging member 330 according to the fourth embodiment. Fig. 28 is a partially enlarged front view of the vicinity of the engaging member 330. Fig. 29 is a partially enlarged bottom view of the vicinity of the engaging member 330, and Fig. 30 is a partially enlarged side view of the vicinity of the engaging member 330 shown in Fig. 29 as viewed from the right side. For ease of understanding, Fig. 27 and other figures show a state in which the case part 312 is removed.

[0139] 27 to 30, engaging member 330 includes engaging portion 331, connecting portion 332, shaft portion 336, and releasing portion 341. Engaging portion 331, connecting portion 332, shaft portion 336, and releasing portion 341 are integrally formed.

[0140] In this manner, in the fourth embodiment, the engagement portion 331 having the function of engaging with the holding portion 320 and the release portion 341 having the function of releasing the engagement are integrally formed, thereby making it possible to reduce the number of parts.

[0141] Engagement member 330 is disposed within remote control body 10 so as to be rotatable about the up-down direction (Z-axis direction). More specifically, shaft 336 is positioned near the center of engagement member 330. Connection portion 332 and engagement portion 331 are positioned on the right side of shaft 336, and release portion 341 is positioned on the left side. That is, engagement portion 331, connection portion 332, shaft 336, and release portion 341 are positioned so as to be aligned along the left-right direction.

[0142] 29, for example, an insertion hole 336a is formed near the center of the shaft portion 336, penetrating in the vertical direction. A protrusion 316 is formed in the base portion 311 at a position corresponding to the insertion hole 336a, extending in the vertical direction. By inserting the protrusion 316 into the insertion hole 336a, the engagement member 330 becomes rotatable about the protrusion 316, in other words, about the vertical direction. In FIGS. 28 and 29, the rotation axis is indicated by the symbol E31.

[0143] As described above, spring 350 is attached to engaging member 330 that is rotatably disposed, and biases engaging member 330 in a predetermined rotational direction. Spring 350 may be, for example, a torsion spring, but is not limited thereto, and may be any other type of elastic member that can elastically deform to generate a biasing force, such as a coil spring, a leaf spring, or a disc spring.

[0144] One end 350a of the spring 350 is fixed to an appropriate position on the base portion 311, and the other end 350b is fixed to the release portion 341 of the engagement member 330. The spring 350 biases the engagement member 330 in a clockwise rotational direction when viewed from below in Fig. 29. That is, the spring 350 biases the release portion 341 forward, and biases the engagement portion 331 and the connection portion 332 backward.

[0145] The engaging portion 331 receives a biasing force from the spring 350, and engages with the holding portion 320 to fix the remote control body 310 to the holding portion 320. Specifically, as shown in Fig. 30, the engaging portion 331 is formed with an engaging groove 331a that opens toward the rear.

[0146] When remote control main body 310 is held by holding portion 320, pedestal portion 322 of holding portion 320 and mounting portion 314 of base portion 311 placed on pedestal portion 322 are located at a position corresponding to engagement groove 331a of engagement portion 331. Therefore, engagement portion 331 receives the biasing force of spring 350 and moves rearward, and pedestal portion 322 and mounting portion 314 enter engagement groove 331a, thereby engaging with holding portion 320.

[0147] 27 to 29, the connecting portion 332 connects the engaging portion 331 and the shaft portion 336. As shown in Figs. 27 and 28, the releasing portion 341 has a columnar portion extending in the vertical direction, for example, and an end portion 341a near the lower front portion of the columnar portion is operated by an operator to release the engagement.

[0148] The release operation will be described below with reference to Figures 31 and 32. Figure 31 is a bottom view showing the state in which the engagement between holding portion 320 and engaging portion 331 has been released, and corresponds to Figure 29. Figure 32 is a side view showing the state in which the engagement between holding portion 320 and engaging portion 331 has been released, as viewed from the right side, and corresponds to Figure 30.

[0149] As shown in Fig. 31, the release operation is first performed by operating release portion 341 of engagement member 330 from diagonally below remote control body 310 with respect to the horizontal plane (see Fig. 9 shown in the first embodiment). In detail, release portion 341 is operated by tool T from diagonally below the front side of remote control body 310 in a direction along underside 310a, more specifically, along the front-rear direction (rear to be precise) of remote control body 310 (see arrow D31).

[0150] At this time, tool T is inserted into opening 312b on underside 310a of remote control main body 310 shown in FIG. 25, accessing end 341a of release portion 341 and sliding release portion 341 in the front-to-back direction (rearward to be precise).

[0151] Although not shown in the figures, in the fourth embodiment, even if the working space below the remote control device 3 is reduced by a counter C or the like, the worker can access the release portion 341 from diagonally below the remote control body 310, thereby disengaging the holding portion 320 from the engagement portion 331, thereby further improving the ease of attachment and detachment.

[0152] Then, when the release portion 341 is slid backward against the biasing force of the spring 350, the engagement member 330 rotates counterclockwise around the rotation axis E31 in a bottom view. Therefore, as shown by an arrow D32 in Figures 31 and 32, the engagement portion 331 is moved in a direction away from the base portion 322 and the mounting portion 314 (i.e., forward), and thus the base portion 322 and the mounting portion 314 are no longer engaged with the engagement groove 331a. This allows the engagement between the holding portion 320 and the engagement portion 331 to be released.

[0153] Fifth embodiment Next, a fifth embodiment will be described. In the following description of the fifth embodiment, configurations corresponding to those of the first embodiment may be designated by adding the number "4" to the beginning of the reference numeral.

[0154] Fig. 33 is a bottom view of the remote control device 3 according to the fifth embodiment. As shown in Fig. 33, the engagement member 430 according to the fifth embodiment includes a release portion 441. That is, in the fifth embodiment, the engagement member 430 includes the release portion 441, and thus has a function of releasing the engagement with the holding portion 20 in addition to a function of engaging with the holding portion 20.

[0155] In the fifth embodiment, the release portion 441 is configured to be able to release the engagement between the holding portion 20 and the engagement portion 431 by being operated and moved in a direction along the underside 10a of the remote control body 10, more specifically, along the left-right direction (X-axis direction) of the remote control body 10. The detailed configuration of the engagement member 430 including the release portion 441 will be described later with reference to FIG. 34 etc.

[0156] Here, first, a description will be given of the position where the release part 441 is arranged on the remote control body 10. As shown in Fig. 33, an opening 412b is formed in the lower surface 412a of the case part 412. The opening 412b is, for example, a long slit, and is formed along the left-right direction of the remote control body 10.

[0157] Similarly to the first embodiment, the release section 441 is housed in the case section 412 and arranged at a position corresponding to the opening 412b of the case section 412, more specifically, at a position visible from the opening 412b. That is, the release section 441 is arranged at a position visible when viewed from the bottom of the remote control body 10. On the other hand, the release section 441 according to the fifth embodiment is housed in the case section 412 without protruding from the bottom surface 10a of the remote control body 10 as shown in FIG. 2, and therefore arranged at a position hidden when viewed from the front of the remote control body 10.

[0158] As a result, in the fifth embodiment, like the first embodiment, it is possible to prevent the remote control body 10 from being stolen, while improving ease of attachment and detachment.

[0159] 33, in the fifth embodiment, similarly to the third embodiment, the case part 412 includes the cover part 413, and the engagement part 431 is configured to be arranged in a position where the engagement part with the holding part 20 is hidden when viewed from below the remote control body 10. This makes it possible to more effectively prevent theft of the remote control body 10.

[0160] Next, the remote control device 3 according to the fifth embodiment will be described in detail with reference to Fig. 34 onwards. Fig. 34 is a partially enlarged perspective view showing an enlarged view of the lower part of the remote control device 3 according to the fifth embodiment, and Fig. 35 is a partially enlarged front view showing an enlarged view of the lower part of the remote control device 3 according to the fifth embodiment. For ease of understanding, Figs. 34 and 35 show a state in which case 412 has been removed.

[0161] As shown in FIGS. 34 and 35, engaging member 430 includes engaging portion 431, connecting portion 432, pressing portion 433, and releasing portion 441, and is disposed within remote control body 10 so as to be movable along the left-right direction (X-axis direction).

[0162] The engaging portion 431, the connecting portion 432, the pressing portion 433, and the releasing portion 441 are integrally formed. In this manner, in the fifth embodiment, the engaging portion 431 having the function of engaging with the holding portion 20 and the releasing portion 441 having the function of releasing the engagement are integrally formed, so that the number of parts can be reduced.

[0163] The engaging portion 431 engages with the holding portion 20 by an engaging claw 431a. A release portion 441 is located below the engaging portion 431.

[0164] The release portion 441 includes a recess 445. The recess 445 is a groove-like portion formed on a lower surface 441a of the release portion 441 and extending along the left-right direction of the remote control body 10. The recess 445 is shaped such that the left side is open on the lower surface 441a of the release portion 441. In detail, the recess 445 is formed so that the opposite side (here, the left side) to the direction in which the engagement member 430 moves when the engagement is released (here, the right side) is open.

[0165] Thereby, for example, during a release operation, the recess 445 allows a tool T (not shown in FIGS. 34 and 35) to be inserted from the left side, and the inserted tool T can be locked.

[0166] Next, release of the engagement will be described with reference to Fig. 36. Fig. 36 is a diagram showing a state in which the engagement between the holding part 20 and the engagement part 431 has been released by a releasing operation.

[0167] 36, the release operation is performed on the release portion 441 with a tool T locked in the recess 445. In detail, the tool T is inserted into the recess 445 of the release portion 441 by an operator and locked.

[0168] Then, with the inserted tool T locked, the release portion 441 is operated by the operator along the left-right direction (to be precise, to the right) of the remote control device 3 (see arrow D41). As a result, as shown by arrow D42, the engagement member 430 moves (slides) in the left-right direction (to be precise, to the right) of the remote control device 3 while resisting the biasing force of the spring 50, and the engagement between the holding portion 20 and the engagement portion 431 is released.

[0169] Although not shown in the figures, in the fifth embodiment, even if the working space below the remote control device 3 is reduced by a counter C or the like, the worker can access the release portion 441 from diagonally below the remote control main body 10, thereby disengaging the holding portion 20 from the engagement portion 431, thereby further improving the ease of installation and removal.

[0170] Sixth embodiment Next, a sixth embodiment will be described. In the following description of the sixth embodiment, configurations corresponding to those of the first embodiment may be designated by adding the number "5" to the beginning of the reference numeral.

[0171] Fig. 37 is a bottom view of the remote control device 3 according to the sixth embodiment. As shown in Fig. 37, the engagement member 530 according to the sixth embodiment includes a release portion 541. That is, in the sixth embodiment, the engagement member 530 also includes the release portion 541, and thus has a function of releasing the engagement with the holding portion 20 in addition to a function of engaging with the holding portion 20.

[0172] In the sixth embodiment, the release portion 541 is operated and moved in a direction along the lower surface 10a of the remote control body 10, more specifically, in the left-right direction (X-axis direction) of the remote control body 10, thereby enabling the release of the engagement between the holding portion 20 and the engagement portion 531. Details of the engagement member 530 including the release portion 541 will be described later with reference to FIG. 38 etc.

[0173] Here, first, a description will be given of the position where release part 541 is arranged in remote control body 10. As shown in Fig. 37, opening 512b is formed in lower surface 512a of case part 512. Opening 512b is, for example, a long slit, and is formed along the left-right direction of remote control body 10.

[0174] Similarly to the first embodiment, the release section 541 is housed in the case section 512 and arranged at a position corresponding to the opening 512b of the case section 512, more specifically, at a position visible from the opening 512b. That is, the release section 541 is arranged at a position visible when viewed from the bottom of the remote control body 10. The release section 541 according to the sixth embodiment is housed in the case section 512 without protruding from the bottom surface 10a of the remote control body 10 as shown in FIG. 2, and therefore arranged at a position hidden when viewed from the front of the remote control body 10.

[0175] As a result, in the sixth embodiment, like the first embodiment, it is possible to prevent the remote control body 10 from being stolen, while improving ease of attachment and detachment.

[0176] 37, in the sixth embodiment, as in the third and fifth embodiments, case part 512 includes cover part 513, and engagement part 531 is disposed at a position where the engagement part with holding part 20 is hidden when viewed from below of remote control body 10. This makes it possible to more effectively prevent theft of remote control body 10.

[0177] Next, the remote control device 3 according to the sixth embodiment will be described in detail with reference to Fig. 38 onwards. Fig. 38 is a partially enlarged perspective view showing an enlarged view of the vicinity of the lower part of the remote control device 3 according to the sixth embodiment, and Fig. 39 is a partially enlarged front view showing an enlarged view of the vicinity of the lower part of the remote control device 3 according to the sixth embodiment. For ease of understanding, Figs. 38 and 39 show a state in which case part 512 is removed.

[0178] As shown in FIGS. 38 and 39, engaging member 530 includes engaging portion 531, connecting portion 532, pressing portion 533, and releasing portion 541, and is disposed within remote control body 10 so as to be movable in the left-right direction (X-axis direction).

[0179] The engaging portion 531, the connecting portion 532, the pressing portion 533, and the releasing portion 541 are integrally formed. That is, by integrally forming the engaging portion 531, the releasing portion 541, etc., it is possible to reduce the number of parts.

[0180] The engaging portion 531 engages with the holding portion 20 by an engaging claw 531a. A release portion 541 is located below the engaging portion 531.

[0181] The release portion 541 includes a recess 545. The recess 545 is formed along the front-rear direction of the remote control body 10.

[0182] For example, recess 545 is a groove-like portion formed on lower surface 541a of release portion 541 and extending along the front-rear direction of remote control body 10. Recess 545 is shaped such that the front side (near side) is open on lower surface 541a of release portion 541. In detail, recess 545 is formed so that one side (here, the front) in a direction (here, the front-rear direction) intersecting with the direction in which engagement member 530 moves when engagement is released (here, the left-right direction) is opened.

[0183] Thereby, for example, during a release operation, the recess 545 allows a tool T (not shown in FIGS. 38 and 39) to be inserted from the front side, and the inserted tool T can be locked.

[0184] Next, the release of the engagement will be described with reference to Figures 40 and 41. Figure 40 is a diagram showing a state in which the engagement between the holding part 20 and the engagement part 531 has been released by the release operation. Figure 41 is a partially enlarged perspective view of the vicinity of the engagement member 430 where the release operation is being performed.

[0185] 40 and 41, the release operation is performed on the release portion 541 with the tool T locked in the recess 545. In detail, the operator inserts the tool T into the recess 545 of the release portion 541 from the front and locks it.

[0186] With the inserted tool T locked, the release part 541 is operated by the operator in the left-right direction (to be precise, rightward) of the remote control device 3 (see arrow D51). Thus, in the sixth embodiment, the insertion direction of the tool T into the recess 545 and the direction in which the release part 541 is operated during the release operation are made different.

[0187] Then, as indicated by arrow D52 in FIG. 40, the engagement member 530 moves (slides) in the left-right direction (to the right, to be precise) of the remote control device 3 against the biasing force of the spring 50, and the engagement between the holding portion 20 and the engagement portion 531 is released.

[0188] In the sixth embodiment, the above-mentioned configuration effectively prevents theft of the remote control body 10. That is, while the insertion direction of the tool T into the recess 545 is the front-rear direction of the remote control body 10, the release part 541 is operated along the left-right direction of the remote control body 10. Therefore, even if a would-be thief inserts something relatively weak other than a tool (for example, folded cardboard or thin paper, a nail, etc.) into the recess, it becomes difficult to operate the release part 541 in the left-right direction, and therefore the theft of the remote control body 10 can be effectively prevented.

[0189] Although not shown in the figures, in the sixth embodiment, even if the working space below the remote control device 3 is reduced by a counter C or the like, the worker can access the release portion 541 from diagonally below the remote control main body 10, thereby disengaging the holding portion 20 from the engagement portion 531, thereby further improving the ease of installation and removal.

[0190] Seventh embodiment Next, a seventh embodiment will be described. In the following description of the seventh embodiment, configurations corresponding to those of the first embodiment may be designated by adding the number "6" to the beginning of the reference numeral.

[0191] Fig. 42 is a front view of the remote control device 3 according to the seventh embodiment. Fig. 43 is an exploded perspective view of the remote control device 3 according to the seventh embodiment. Note that, as the remote control device 3 according to the seventh embodiment, for example, a remote control device that is relatively long in the left-right direction can be used, but is not limited to this.

[0192] As shown in Figs. 42 and 43, the remote control device 3 according to the seventh embodiment includes a remote control main body 610 and a holding part 620 (not visible in Fig. 42). The remote control main body 610 includes a base part 611 and a case part 612. The holding part 620 includes a hook part 660. For example, the hook parts 660 are formed on the left and right sides near the lower part of the holding part 620. In the seventh embodiment, the remote control main body 610 is fixed to the holding part 620 by the hook parts 660. The detailed configuration of the hook parts 660 will be described later with reference to Fig. 45.

[0193] FIG. 44 is a rear view of the remote control body 610. As shown in FIG. 44, the remote control body 610 includes an engagement portion 631 that can engage with the hook portion 660 described above. For example, the engagement portion 631 is formed on the rear surface 611a of the remote control body 610 (more precisely, on the rear surface 611a of the base portion 611) at a position corresponding to the hook portion 660 of the holding portion 620. Specifically, the engagement portion 631 is formed on the left and right sides near the lower portion of the remote control body 610. The engagement portion 631 is an engagement groove that opens toward the rear. Note that, although an example in which there are a plurality of hook portions 660 and a plurality of engagement portions 631 (two in this case) are shown in FIG. 43 and FIG. 44, such a number is merely an example and is not limited thereto.

[0194] Next, the remote control device 3 according to the seventh embodiment will be described in detail with reference to Fig. 45. Fig. 45 is a cross-sectional view taken along line XLV-XLV in Fig. 42.

[0195] 45, hook portion 660 includes a support portion 661 and an engaging claw 662, and is made of a flexible material (such as resin).

[0196] In this way, in the seventh embodiment, since the holding portion 620 and the hook portion 660 are integrally formed, the number of parts can be reduced.

[0197] The support portion 661 is a portion formed, for example, in a columnar shape. For example, the support portion 661 is formed in the holding portion 620 so as to extend downward (Z-axis negative direction) from a predetermined position 623 that is hidden by the remote control body 610 in a front view when the remote control body 610 is fixed. An engagement claw 662 is formed at the tip (lower end) of the support portion 661. As described above, the support portion 661 is made of a flexible material, and therefore the hook portion 660 including the support portion 661 can bend, for example, in the horizontal direction (front-rear direction), in other words, can be elastically deformed in the horizontal direction (front-rear direction).

[0198] The engagement claw 662 is formed so as to protrude forward (in the positive direction of the Y-axis) from the tip of the support portion 661, for example. When the remote control main body 610 is attached to the holding portion 620, the engagement claw 662 engages with the engagement portion 631 of the remote control main body 610. That is, when the remote control main body 610 is attached to the holding portion 620, the worker moves the remote control main body 610 from above to below with respect to the holding portion 620, and when the engagement portion 631 of the remote control main body 610 reaches the position of the engagement claw 662, the engagement claw 662 enters the engagement portion 631 which is an engagement groove. As a result, the engagement claw 662 and the engagement portion 631 engage with each other, and the remote control main body 610 is fixed to the holding portion 620.

[0199] Moreover, the hook portion 660 includes a releasing portion 641. That is, by including the releasing portion 641, the hook portion 660 according to the seventh embodiment has a function of releasing the engagement with the engaging portion 631, in addition to the function of engaging with the engaging portion 631.

[0200] The release portion 641 is formed on the hook portion 660. More specifically, the release portion 641 is formed on a lower surface 662a of the engagement claw 662 of the hook portion 660.

[0201] Here, the position of release portion 641 will be described. As shown in Fig. 45, the lower side of release portion 641 is free of parts of remote control body 610 and is open. Therefore, release portion 641 is arranged at a position visible when viewed from below of remote control body 610. On the other hand, engagement claw 662 of hook portion 660 on which release portion 641 is formed engages with engagement portion 631 formed on rear surface 611a of remote control body 610 as described above. Therefore, release portion 641 is arranged at a position hidden when viewed from the front of remote control body 610 (see Fig. 42).

[0202] Thus, in the seventh embodiment, like the first embodiment, it is possible to prevent the remote control body 610 from being stolen, while improving ease of attachment and detachment.

[0203] Further, the release portion 641 includes a recess 645. The recess 645 is, for example, a groove-shaped portion that opens downward. Therefore, for example, during a release operation, the recess 645 of the release portion 641 allows a tool T to be inserted from below, and the inserted tool T can be locked.

[0204] Next, release of the engagement will be described. The release operation is performed with the tool T locked in the recess 645 of the release portion 641. More specifically, the operator inserts the tool T into the recess 645 of the release portion 641 and locks it.

[0205] With the tool T locked in the recess 645, the operator operates (presses) the release portion 641 along the front-rear direction of the remote control device 3, more precisely, along the rear (see arrow D61). As a result, as shown by imaginary lines in Fig. 45, the hook portion 660 is deflected in the horizontal direction (for example, in the front-rear direction (more precisely, rearward)), so that the engagement claw 662 comes out of the engagement portion 631, and the engagement between the holding portion 620 and the engagement portion 631 is released.

[0206] In this way, in the seventh embodiment, the holding portion 620 includes the hook portion 660 including the engaging claw 662, and the releasing portion 641 includes the recess 645 formed in the hook portion 660. The releasing portion 641 is configured so that, with the tool T engaged in the recess 645, the hook portion 660 bends to release the engagement between the holding portion 620 and the engaging portion 631. This makes it possible to effectively prevent theft of the remote control body 610 with a simple configuration.

[0207] Although not shown in the figures, in the seventh embodiment, even if the working space below the remote control device 3 is reduced by a counter C or the like, the worker can access the release portion 641 from diagonally below the remote control body 610, thereby disengaging the holding portion 620 from the engagement portion 631, thereby further improving the ease of installation and removal.

[0208] Eighth embodiment Next, an eighth embodiment will be described. In the following description of the eighth embodiment, configurations corresponding to those of the first embodiment may be designated by adding the number "7" to the beginning of the reference numeral.

[0209] 46 is an exploded perspective view of the remote control device 3 according to the eighth embodiment. As the remote control device 3 according to the eighth embodiment, a remote control device that is relatively long in the left-right direction can be used, as in the seventh embodiment, but is not limited thereto.

[0210] 46, the remote control device 3 according to the eighth embodiment includes a remote control body 710, a holding portion 720, and a hook portion 760. The remote control body 710 includes a base portion 711 and a case portion 712.

[0211] Holding portion 720 is formed, for example, in a substantially L-shape when viewed from the side (when viewed in the X-axis direction). Specifically, holding portion 720 includes a rear portion 724 and a bottom portion 725. Rear portion 724 is a plate-shaped portion located on the rear side of remote control main body 710 when remote control main body 710 is fixed to holding portion 720. Bottom portion 725 is a plate-shaped portion located on the bottom side (lower surface side) of remote control main body 710 when remote control main body 710 is fixed to holding portion 720.

[0212] Hook portion 760 is provided on holding portion 720. For example, hook portion 760 is provided near the lower portion of holding portion 720, on the left and right sides of bottom surface portion 725. More specifically, hook portion 760 is provided in openings 725a that are opened on the left and right sides of bottom surface portion 725. Hook portion 760 is a separate body from holding portion 720. In the eighth embodiment, remote control main body 710 is fixed to holding portion 720 by hook portion 760. The detailed configuration of hook portion 760 will be described later with reference to Figs. 48 to 49B.

[0213] FIG. 47 is a bottom view of the remote control body 710. As shown in FIG. 47, the remote control body 710 includes an engagement portion 731 that can engage with the hook portion 760 described above. For example, the engagement portion 731 is formed on the bottom surface 710a of the remote control body 710 (more precisely, the bottom surface 712a of the case portion 712) at a position corresponding to the hook portion 760 of the holding portion 720. Specifically, the engagement portion 731 is formed on the left and right sides near the bottom of the remote control body 710. The engagement portion 731 is an engagement groove that opens downward. Note that, although an example in which there are a plurality of hook portions 760 and a plurality of engagement portions 731 (two in this case) are shown in FIG. 46 and FIG. 47, such a number is merely an example and is not limited thereto.

[0214] Next, the remote control device 3 according to the eighth embodiment will be described in detail with reference to Fig. 48. Fig. 48 is a cross-sectional view taken along line XLVIII-XLVIII in Fig. 46, and is a vertical cross-sectional view of the remote control device 3 in a state where the remote control main body 710 is fixed to the holding part 720.

[0215] 48, hook portion 760 is configured to be able to engage with engaging portion 731, which will be described in detail later. Hook portion 760 includes releasing portion 741. That is, hook portion 760 according to the eighth embodiment includes releasing portion 741, and thus has a function of releasing the engagement in addition to a function of engaging with engaging portion 731.

[0216] Here, the position of release portion 741 will be described. As shown in Fig. 48, release portion 741 is located within opening 725a of holding portion 720. Therefore, release portion 741 is arranged at a position visible when viewed from below of remote control body 710. On the other hand, release portion 741 is located within opening 725a, and therefore arranged at a position hidden when remote control body 710 is viewed from the front.

[0217] Thus, in the eighth embodiment, like the first embodiment, it is possible to prevent the remote control body 710 from being stolen, while improving ease of attachment and detachment.

[0218] Next, the detailed configuration of hook portion 760 etc. will be described with reference to Figures 49A and 49B. Figure 49A is a partially enlarged view of Figure 48, specifically an enlarged cross-sectional view enlarging the vicinity of hook portion 760 in detail. Also, Figure 49B is a partially enlarged view showing a state in which the engagement between hook portion 760 and engagement portion 731 has been released.

[0219] As shown in FIG. 49A, hook portion 760 is an elongated member, and includes a connecting portion 761, an engaging claw 762, a rotating shaft portion 763, and release portion 741 described above.

[0220] The connecting portion 761 connects the engagement claw 762 and the rotation shaft portion 763. The engagement claw 762 engages with the engagement portion 731 of the remote control body 710, and fixes the remote control body 710 to the holding portion 720. For example, the engagement claw 762 is formed on one end of the hook portion 760 (more specifically, on one end of the connecting portion 761).

[0221] Specifically, the engagement claw 762 is formed so as to protrude upward (in the positive direction of the Z axis) from one end of the hook portion 760. More precisely, the engagement claw 762 is formed so as to protrude obliquely upward from one end of the hook portion 760 so as to be inclined toward the connecting portion 761 side, and is formed so that an engagement portion 762a with the engagement portion 731 has a curved shape.

[0222] On the other hand, the engaging portion 731 is formed so as to correspond to the shape of the engaging claw 762, in other words, it is formed so as to follow the shape of the engaging claw 762. That is, the engaging portion 731 which is an engaging groove is formed so that an engaging portion 731a with the engaging claw 762 has a curved shape. In this way, since the engaging claw 762 and the engaging portion 731 are formed in a curved shape, the engaging claw 762 becomes easily caught by the engaging portion 731, and therefore it becomes possible to reliably engage with the engaging portion 731.

[0223] The rotating shaft portion 763 is supported by the holding portion 720 so that the hook portion 760 can be rotated (turned) along the vertical direction (Z-axis direction). For example, the rotating shaft portion 763 is formed at the other end of the connecting portion 761 and has an insertion hole 763a. In the holding portion 720, a cylindrical portion 726 extending in the front-rear direction (Y-axis direction) is formed at a position corresponding to the insertion hole 763a. By inserting the insertion hole 763a of the rotating shaft portion 763 into the cylindrical portion 726, the hook portion 760 is supported by the holding portion 720 and can be rotated along the vertical direction around the cylindrical portion 726, in other words, around the front-rear direction (see arrow D71). In FIG. 49A, the rotation axis of the hook portion 760 is indicated by the symbol E71.

[0224] Here, the fixing of the remote control main body 710 to the holding part 720 will be described. First, when fixing the remote control main body 710 to the holding part 720 from a state in which the engagement between the hook part 760 and the engagement part 731 is released (see FIG. 49B), an operator operates and presses the vicinity of the engagement claw 762 of the hook part 760 from below upward (see dashed arrow D72). Since the hook part 760 is rotatable, the above-mentioned pressing causes it to rotate counterclockwise around the rotation axis E71, and the engagement claw 762 is pushed into the engagement part 731, which is an engagement groove. As a result, the engagement claw 762 and the engagement part 731 engage with each other, and thus the remote control main body 710 is fixed to the holding part 720.

[0225] The release portion 741 is formed on the other end of the hook portion 760. In detail, the release portion 741 is provided on the hook portion 760 at a position on the opposite side to the engagement claw 762 with respect to the rotation shaft portion 763.

[0226] Here, the release of the engagement will be described. In the release portion 741, the release operation is performed with a tool T in contact with the lower surface 741a. In more detail, the operator brings the tool T into contact with the lower surface 741a of the release portion 741. Then, with the tool T in contact with the release portion 741, the operator operates (presses) the release portion 741 from below toward above (see arrow D73).

[0227] As a result, as shown by arrow D74 in Figure 49B, the hook portion 760 rotates along the vertical direction (in other words, rotates clockwise around the rotation axis E71), causing the engagement claw 762 to come out of the engagement portion 731 and disengage the holding portion 720 from the engagement portion 731.

[0228] Thus, in the eighth embodiment, hook portion 760 including engaging claw 762, rotating shaft portion 763, and release portion 741 is provided, and release portion 741 is configured to be able to release the engagement between holding portion 720 and engaging portion 731 by rotating hook portion 760 when operated from below to above. This makes it possible to effectively prevent theft of remote control main body 710 with a simple configuration.

[0229] Although not shown in the figures, in the eighth embodiment, even if the working space below the remote control device 3 is reduced by a counter C or the like, the worker can access the release portion 741 from diagonally below the remote control body 710, thereby disengaging the holding portion 720 from the engagement portion 731, thereby further improving the ease of installation and removal.

[0230] In the above-described embodiments, the remote control device 3 is provided in the toilet room R, but the present invention is not limited to this. For example, the remote control device 3 may be provided in a water-related space such as a washroom or a kitchen, and may remotely control water-related equipment such as an automatic faucet device.

[0231] Further advantages and modifications may readily occur to those skilled in the art. Thus, the invention in its broader aspects is not limited to the specific details and representative embodiments shown and described above. Accordingly, various modifications may be made without departing from the spirit or scope of the general inventive concept as defined by the appended claims and equivalents thereof.
