As shown in FIGS. 1 and 3, the input unit 21 includes a housing 211 and a pair of connection pins 212.

The casing 211 is formed of, for example, a resin material, and has electrical insulation. The housing 211 is formed in a cylindrical shape. The housing 211 has a flange at the upper end and a hemispherical protrusion protruding downward on the lower bottom surface side. A pair of connection pins 212 protrudes from the upper surface of the housing 211. The interval between a pair of connection pins 212 of the input portion 21 is substantially the same as the interval between a pair of connection holes 112 of the connection portion 11 of the first unit 10. At the lower end of the hemispherical protrusion of the housing 211, a hole for passing the second unit side cable 23 is formed. In addition, in the housing 211, a magnetic body as a second coupling portion 210 is housed (see FIG. 2). The second coupling portion 210 can be coupled to the first coupling portion 110 accommodated in the housing 111 of the connection portion 11 of the first unit 10 by magnetic force.

The functional unit 22 is the socket body 220 in this embodiment. The socket body 220 includes a housing 221 and a socket portion 222 housed in the housing 221.

The housing 221 is made of synthetic resin, for example, ABS resin. The housing 221 has a "longitudinal length" shape that is long in one direction (upper and lower directions in FIG. 1) and is flat in one direction (thickness direction) in a plane orthogonal to the longitudinal direction. The housing 221 is connected to the second unit side cable 23 at the first end 2211 in the longitudinal direction. In addition, as the housing 221 approaches the first end 2211 from the second end 2212 in the longitudinal direction, its thickness and width gradually decrease in a tapered shape. The housing 221 adopts a shape connected from the second end 2212 to the first end 2211 without a step, so-called "ONE MOTION FORM". Specifically, the outer peripheral surface of the housing 221 is gently curved to protrude inward from the second end 2212 to a middle portion in the longitudinal direction. Furthermore, when viewed from a direction parallel to the longitudinal direction, the outer peripheral surface of the housing 221 is a curved surface that is connected without a step difference over the entire circumference. The surface of the housing 221 is composed of an uneven surface subjected to wrinkle processing (embossing processing). The "wrinkle processing" referred to here refers to the processing of imparting fine uneven wrinkles to the surface of the housing 221 when the housing 221 is formed.

The housing 221 is formed by combining two components of the body 2213 and the cover 2214. The main body 2213 and the cover 2214 have openings on the surfaces facing each other, and are combined in such a manner that their openings are aligned with each other. Thereby, an internal space for accommodating the socket portion 222 and the like is formed between the body 2213 and the cover 2214. The main body 2213 and the cover 2214 are, for example, a plurality of coupling claws protruding from the inner peripheral edge of the other opening of the main body 2213 and the lid 2214 hooking into a plurality of coupling holes formed by the inner peripheral edge of one opening, thereby, Temporarily fixed to each other. In this state, the body 2213 and the cover 2214 are combined by passing a plurality of coupling screws through one of the body 2213 and the cover 2214 and fixing the other.

At the first end 2211 of the housing 221, an introduction hole for passing the second unit side cable 23 is formed. The introduction hole is a circular hole formed in the end surface of the first end 2211 of the housing 221. In this embodiment, a pair of semicircular notches formed in the body 2213 and the cover 2214 are combined to form a circular introduction hole.

In addition, an opening 2216 for exposing the socket 222 is formed at the second end 2212 of the housing 221. The opening 2216 is a hole that penetrates the wall on the second end 2212 side of the housing 221 and is formed in a rectangular shape that is long in the width direction of the housing 221. In addition, the opening 2216 may be formed on the side of the housing 221, for example.

In addition, the housing 221 further has a pair of hooks 2217 protruding from the surface of the main body 2213 opposite to the cover 2214 (only one is shown in FIGS. 1 and 3). The pair of hooks 2217 are used to hook the power cord extending from the plug of the electrical device 301. As a result, the suspended electrical appliance 100 is in a state where the plug is connected to the socket body 220, and the hook 2217 can bear the load acting on the plug due to the weight of the power cord or the like.

The socket part 222 has a built-in member such as a housing 2221 made of synthetic resin and a blade bearing member accommodated in the housing 2221. The socket portion 222 is housed in the housing 221 so that one surface (connection surface) 2222 of the housing 2221 is exposed from the opening 2216. On the connection surface 2222, two connection ports 2220 for inserting a plug blade (or pin) of the plug are formed. The socket part 222 is provided with a stopper mechanism for preventing the plug blade (or pin) of the plug by turning the plug.

The second unit side cable 23 is composed of a flexible insulated wire, for example, a vinyl round insulated wire. The insulated wire includes the above-mentioned wire (a pair of power wires) and a sheath made of an insulating material covering the wire. The second unit side cable 23 has a first end 231 and a second end 232. The first end 231 of the second unit-side cable 23 is connected to the functional unit 22 (socket body 220 ), and the second end 232 of the second unit-side cable 23 is connected to the input unit 21. The first end of the insulated wire is introduced into the housing 221 of the socket body 220 after passing through the introduction hole, and is branched into two branched insulated wires in the housing 221. Each branch insulated wire is connected to the terminal portion (so-called quick junction terminal) of the corresponding connection port 2220 of the two connection ports 2220. The second end of the insulated wire (a pair of power wires) is connected to the connection pin 212 in the housing 211 of the input unit 21.

(2.4) Installation of the first unit of the wiring duct

As shown in FIG. 1, the first unit 10 is attached to the wiring duct 80 by attaching the mounting portion 12 to the wiring duct 80.

For example, first, the mounting portion 12 is positioned on the wiring duct 80 in such a manner that the protruding direction of the pair of protruding portions 1212 of the connecting member 121 coincides with the longitudinal direction of the connecting recessed portion 821 (the longitudinal direction of the catheter body 82). Below. Then, after inserting the pair of protruding portions 1212 into the connecting recess 821 from below, the mounting portion 12 is rotated 90 degrees around the axis of the cylindrical body 1210. As a result, the protrusion 1212 is inserted into the gap between the tongue 822 of the catheter body 82 and the conductor holding portion 825, and the protrusion 1212 is held between the tongue 822 and the conductor holding portion 825. In addition, the terminal plate 1211 is inserted into the concave portion 826 of the conductor holding portion 825 to connect the terminal plate 1211 and the conductor 81. According to this procedure, the first unit 10 can be installed at any position in the longitudinal direction of the wiring duct 80.

In addition, in order to facilitate the installation of the mounting portion 12 of the wiring duct 80, the mounting portion 12 may be provided with a rotation assist mechanism that responds to a button operation or a lever operation to make the connecting member 121 (in a cylindrical shape) The axis of the body 1210 is centered) to rotate the cover member 122.

When the first unit 10 is detached from the wiring duct 80, the procedure opposite to the procedure at the time of installation may be performed. That is, the mounting portion 12 is rotated 90 degrees around the axis of the cylindrical body 1210, and after removing the protruding portion 1212 from the tongue portion 822 and the conductor holding portion 825, the mounting portion 12 may be pulled out from the connection recessed portion 821 .

(2.5) Connection to Unit 2 of Unit 1

In the suspension type electric appliance 100 of this embodiment, the pair of connection pins 212 of the input unit 21 are connected to the pair of connection pins 212 of the input unit 21 by inserting the pair of connection pins 212 of the input unit 21 into the pair of connection holes 112 of the connection unit 11. The pair of connection terminals of the portion 11 are connected. As a result, the second unit 20 (the input section 21) and the first unit 10 (the connecting section 11) are electrically connected (see FIG. 2). At this time, the first coupling portion 110 (magnet) of the connection portion 11 and the second coupling portion 210 (magnetic body) of the input portion 21 are coupled to each other by magnetic force, and the magnetic force is maintained between the first unit 10 and the second unit 20 Positional relationship.

The connection portion 11 is configured to be exclusively (only) electrically and mechanically connected to the input portion 21 of the second unit 20.

For example, the connection section 11 has a universal plug that cannot be connected (JIS C 8303 plug, NEMA1-15 plug, NEMA5-15 plug, BS1363 plug, CPCS-CCC plug, or AS/NZS3112 plug, BS546 plug, BS4573 plug, CEE7/4 (Plug, CEE7/5 plug, CEE7/17 plug, 107-2-D1 plug, CEI23-16/VII plug, SEV1011 plug, IEC60906-1 plug, TIS166-2549 plug, CEE7/4 plug, AS/NZS3112 plug, etc.) Of construction. For example, the shape of the connection hole 112 may be different from the shape of the male connector (plug blade or pin) of the plug, or the interval between a pair of connection holes 112 may be different from the interval between one of the plug and the male connector. Also, the distance between the lower surface of the housing 111 (connection hole 112) and the connection terminal may be longer than the length of the male connector of the universal plug. In addition, a concave-convex structure may be formed on the lower surface of the housing 111 of the connecting portion 11 and the upper surface of the housing 211 of the input portion 21 when the connecting pin 212 is inserted into the connecting hole 112.

At this time, the functional unit 22 (socket body 220) is electrically connected to the conductor 81 of the wiring duct 80 via the first unit 10, the input unit 21, and the second unit side cable 23. That is, power can be supplied to the functional unit 22 from a power source (for example, a commercial power source) connected to the wiring duct 80. In this embodiment, since the functional part 22 is the socket body 220, the electrical connection to the connection port 2220 of the socket body 220 is possible. The device 301 supplies electric power (see FIG. 4).

On the other hand, when the functional unit 22 (second unit 20) is not used, the user removes the input unit 21 from the connection unit 11 in advance. Therefore, when the functional unit 22 is not used, there is no possibility that the second unit 20 is located in the field of view and is worried or becomes an obstacle to movement. That is, when the functional unit 22 is not used, the suspended electrical appliance 100 is less likely to be a factor that limits the range of movement of a person. In addition, the user can freely use the space occupied by the second unit 20 when the second unit 20 is connected to the first unit 10 (see FIG. 5 ).

(3) Modification

The above-mentioned embodiment is only one of various embodiments of the present disclosure. As long as the above-mentioned embodiment can achieve the purpose of cost disclosure, various changes can be made according to the design and the like. Hereinafter, a modification of the above-mentioned embodiment will be listed. In the following, the above-mentioned embodiment is referred to as "basic example". The modified examples and basic examples described below can be applied after being combined as appropriate.

(3.1) First modification

6A and 6B, the suspended electrical appliance 100 according to the first modification will be described. The suspension type electric appliance 100 of this modification is mainly provided with the locking mechanism 3, and is different from the suspension type electric appliance 100 of the basic example. The lock mechanism 3 is a release state in which a lock state and a releasable coupling state can be switched. The lock state is a state in which the first unit 10 and the second unit 20 are mechanically coupled to supply power to the input unit 21 via the connection unit 11.

The lock mechanism 3 of this modification includes a holding plate that is rotatably attached to the housing 111 of the connecting portion 11 Member 31. The holding plate member 31 includes: a rectangular plate-shaped first plate portion 311; a second plate portion 312, which protrudes from the first plate portion 311 in the thickness direction of the first plate portion 311; and a shaft portion 313, which connects the first The plate portion 311 holds the housing 111 rotatably.

The first plate portion 311 is formed of, for example, a resin material into a rectangular plate shape that is long in one direction. The first plate portion 311 is provided at its first end with a cylindrical bearing portion whose axial direction is along the width direction (short side direction) of the first plate portion 311. The second plate portion 312 protrudes from the second end of the first plate portion 311 in the thickness direction of the first plate portion 311 (in a direction perpendicular to the longitudinal direction and the width direction of the first plate portion 311). The holding plate member 31 forms an L-shape in side view by the first plate portion 311 and the second plate portion 312. The center portion of the protruding end of the second plate portion 312 is processed with a U-shaped notch to form a cable receiving portion 314. The shaft portion 313 holds the bearing portion of the first plate portion 311 so as to be rotatable about its axial direction. Here, the housing 111 of the connecting portion 11 has a flat portion 113 parallel to the vertical plane at a portion below the side surface. The shaft portion 313 is fixed to the plane portion 113 such that the axial direction is along the plane portion 113 and the horizontal plane. The holding plate member 31 is rotatable between a first state and a second state. The first state is that the longitudinal direction of the first plate portion 311 intersects the axial direction of the cylindrical casing 111 (intersects the flat portion 113) (refer to 6A), the second state is that the longitudinal direction of the first plate portion 311 is along the axial direction of the housing 111 (along the plane portion 113) (see FIG. 6B).

In addition, the housing 211 of the input unit 21 has a flat portion 213 parallel to the vertical plane on its side surface.

As shown by the arrow in FIG. 6A, the input portion 21 of the second unit 20 is moved upward toward the connection portion 11 of the first unit 10, and a pair of connection pins 212 are inserted into the pair of connection holes 112, and then the holding plate The member 31 rotates so that the holding plate member 31 becomes the second state. By this, the second end 232 of the second unit side cable 23 is embedded in the holding plate structure In the cable receiving portion 314 of the piece 31. At this time, the upper surface of the second plate portion 312 (the surface on the side of the first plate portion 311) is in contact with the lower portion of the housing 211 (the tip of the protrusion of the housing 211). That is, the second plate portion 312 of the holding plate member 31 holds the first unit 10 and the second unit 20 in a mechanically coupled state (locked state) (see FIG. 6B ). On the other hand, when the holding plate member 31 is rotated so that the holding plate member 31 becomes the first state, the state in which the first unit 10 and the second unit 20 are mechanically coupled (released state) is released.

Since the suspension type electric appliance 100 of the present modification includes the lock mechanism 3, the possibility of the second unit 20 being accidentally separated from the first unit 10 can be reduced.

Furthermore, as shown in FIG. 6A, a protrusion 315 may be formed on one of the lower bottom surface of the housing 111 of the connection portion 11 and the upper bottom surface of the housing 211 of the input portion 21, and a groove 316 may be formed on the other side. The protrusion 315 has a shape that fits into the groove 316 when the connection pin 212 is inserted into the connection hole 112. According to this structure, when the connecting pin 212 is inserted into the connecting hole 112, the rotation of the input portion 21 of the connecting portion 11 (rotation about the axial direction of the cylindrical housing 211 as the center) is suppressed, so that the connecting portion 11 The mechanical combination with the input section 21 becomes stronger.

In this modification, the holding plate member 31 may be provided in the housing 211 of the input unit 21.

(3.2) Second modification

To each flat portion 113, a variable plate 114 having flexibility such as leather is attached. The male half fastener 321 is provided on the variable plate 114. In addition, a pair of flat portions 213 are formed in the upper portion of the side surface of the housing 211 of the input unit 21. The female half fastener 322 is provided on each flat portion 213.

In a state where a pair of connection pins 212 is inserted into a pair of connection holes 112, as shown by the solid line in FIG. 7, if the male half fastener 321 and the female half fastener 322 are combined with each other, the first unit 10 and the second The unit 20 is in a mechanically coupled state (locked state). On the other hand, as shown by the broken line in FIG. 7, if the coupling state of the male half fastener 321 and the female half fastener 322 is released, the state in which the first unit 10 and the second unit 20 are mechanically coupled (the released state) is released .

Since the suspension type electric appliance 100 of this modification also includes the locking mechanism 3, the possibility of the second unit 20 being accidentally separated from the first unit 10 can be reduced.

In this modification, the female half fastener 322 may be provided in the housing 111 of the connecting portion 11, and the variable plate provided with the male half fastener 321 may be provided in the housing 211 of the input portion 21. The female half fastener can also be arranged on the variable plate, and the male half fastener can be arranged on the casing.

The pair of blade bearings 115 are provided with engagement protrusions 33 bent in a V-shape and locked in the middle in the longitudinal direction. The engaging protrusions 33 of the pair of blade bearings 115 protrude in directions facing each other.

In this modification, a pair of connecting pins 212 are inserted into a pair of connecting holes 112, and the input section 21 is rotated in the clockwise direction, whereby the gap between the pair of blade bearings 115 is widened while the pin 212 is connected越过Snap-in protrusion 33. Thereby, the connecting pin 212 enters the space surrounded by the edge of the connecting hole 112 of the housing 111 and the pair of engaging protrusions 33, and by the edge of the connecting hole 112 and the pair of engaging protrusions 33, The connecting pin 212 is elastically held.

Since the suspension type electric appliance 100 of this modification also includes the locking mechanism 3, the possibility of the second unit 20 being accidentally separated from the first unit 10 can be reduced.

The protruding portion is formed by the through hole connected to the pin 212 in a radial through hole, and the protruding portion is provided on the blade bearing 115 and is engaged with the through hole of the connecting pin 212.

(3.4) Fourth modification

9A to 9C, a suspension type electric appliance 100 according to a fourth modification will be described. The suspension type electric appliance 100 of this modification is different from the structure of the lock mechanism 3, and is different from the suspension type electric appliance 100 of the first modification.

The lock mechanism 3 of this modification includes a cylindrical cover 34. The cover 34 is a cylindrical shape whose inner diameter is slightly larger than the outer diameter of the housing 111 of the connection portion 11, has a hemispherical bottom surface on the upper side, and has an opening on the lower side. On the bottom surface on the upper side of the cover 34, a hole for passing the first unit side cable 13 is formed. The cover 34 is a hole through which the first unit-side cable 13 passes through the bottom surface of the upper side, and is arranged between the connecting portion 11 and the mounting portion 12 so that the opening faces the connecting portion 11 side, and the bottom surface faces the mounting portion 12 side. The cover 34 is movable along the first unit-side cable 13 between the first end 131 and the second end 132 (see FIG. 1) of the first unit-side cable 13.

As shown in FIG. 9A, a spiral groove 341 is formed on the inner surface of the cover 34. As shown in FIGS. 9A and 9B, spiral protrusions are formed on the side surface of the housing 111 of the connecting portion 11 and the side surface of the housing 211 of the input portion 21 in such a manner that the connecting pin 212 is inserted into the connecting hole 112 continuously 342, 343.

As shown by the arrow in FIG. 9A, move the input portion 21 of the second unit 20 upward toward the connection portion 11 of the first unit 10, and insert a pair of connection pins 212 into the pair of connection holes 112, as shown by the arrow of FIG. 9B As shown by the number, if the cover 34 is pushed downward while being turned sideways, the groove 341 along the spiral protrusions 342, 343, one The cover 34 gradually moves downward. That is, the spiral protrusion 343 of the input portion 21 fits into the spiral groove 341 of the cover 34 to hold the mechanically coupled state (locked state) of the first unit 10 and the second unit 20 (refer to FIG. 9C ). On the other hand, when the cover 34 is rotated in the reverse direction during the coupling, the mechanically coupled state (released state) of the first unit 10 and the second unit 20 is released.

Since the suspension type electric appliance 100 of this modification also includes the locking mechanism 3, the possibility of the second unit 20 being accidentally separated from the first unit 10 can be reduced.

In this modification, each of the spiral protrusions 342 and 343 may not be a continuous protrusion, or may be formed from a plurality of protrusions formed along a spiral virtual line. The cover 34 may be provided on the second unit 20 side.

(3.5) Fifth modification

With reference to Fig. 10, a suspended electrical appliance 100 according to a fifth modification will be described. The suspension type electric appliance 100 of this modification mainly differs in the configuration of the mounting portion 12, and the first unit 10 includes a connection cable (connection cable portion) 14 that replaces the first unit side cable 13 and is suspended from the basic example. The hanging electrical appliance 100 is different.

In the suspension type electric appliance 100 of the present embodiment, the attachment portion 12 includes a lateral rotation member 123 instead of the cover member 122.

The horizontal rotating member 123 includes a rotating body 1230, a first support 1231, and a second support 1232. The rotating body 1230 is formed into a cylindrical shape from, for example, a resin material. The first support 1231 is formed of, for example, a resin material It has a bottomed cylindrical shape and is arranged on the upper side of the rotating body 1230 so that the bottom surface becomes the upper side. The connecting member 121 is connected to the bottom surface (upper surface) of the first support 1231. The second support 1232 is formed into a bottomed cylindrical shape with a resin material, for example, and is arranged on the lower side of the rotating body 1230 so that the bottom surface becomes the lower side. The first support body 1231 and the second support body 1232 are arranged above and below the rotating body 1230 in the vertical direction via the rotating body 1230. The first support 1231 and the second support 1232 are fixed to each other. The first support body 1231 and the second support body 1232 hold the rotating body 1230 so that the rotating body 1230 can rotate around the axis of the cylindrical rotating body 1230. The dotted hatched arrows in FIG. 10 indicate the rotating direction of the rotating body 1230. However, the rotation range of the rotating body 1230 is not limited to the range of the dotted hatched arrow, and it can be rotated at any angle around the axis of the rotating body 1230 (that is, the rotating range of the rotating body 1230 is 360°).

The connection cable 14 is connected (held) to the rotating body 1230 and rotates together with the rotating body 1230. The connection cable 14 is held by the rotating body 1230 so as to protrude in a radial direction of the rotating body 1230 from the side surface of the rotating body 1230. That is, the lateral rotation member 123 holds the first end 141 of the connection cable 14 so as to lie in a plane orthogonal to the suspension direction (the vertical direction) of the second unit 20 suspended from the first unit 10. Then, by rotating the rotating body 1230, the connection cable 14 rotates in a plane orthogonal to the suspension direction. The connection portion 11 is connected to the second end 142 of the connection cable 14.

In addition, in this modification, the connection cable 14 has an outer profile 140. The outline 140 includes a first outline 1401 and a second outline 1402. Each of the first outer profile 1401 and the second outer profile 1402 is a metal tube such as stainless steel, and the surface is coated with an insulating synthetic resin. Each of the first outer profile 1401 and the second outer profile 1402 has rigidity that can support the connecting portion 11 at least in the plane. Each of the first outer profile 1401 and the second outer profile 1402 is cylindrical. The outer diameter of the second outer profile 1402 is slightly smaller than the inner diameter of the first outer profile 1401. 1st outline 1401 is located at the first end 141 side of the outer profile 140, and the second outer profile 1402 is located at the second end 142 side of the outer profile 140. By inserting a part of the second outer profile 1402 into the first outer profile 1401, the outer The profile 140 constitutes a tube. In this modification, the length of the outer profile 140 (the length of the connection cable 14) can be adjusted by changing the insertion amount of the second outer profile 1402 into the first outer profile 1401. In addition, the connection cable 14 further includes a fixing member 143 for fixing the relative position of the first outer profile 1401 and the second outer profile 1402. The fixing member 143 is a butterfly screw here. A screw hole is provided at the end of the first outer profile 1401 on the second outer profile 1402 side. The fixing member 143 is screwed into the screw hole so that the front end of the fixing member 143 contacts the outer surface of the second outer profile 1402, whereby the relative position of the first outer profile 1401 and the second outer profile 1402 can be fixed.

In this modification, the first outer profile 1401, the second outer profile 1402, and the fixing member 143 constitute a length adjustment mechanism for adjusting the length of the connection cable 14.

In the outer profile 140 of the connection cable 14, an insulated wire containing wires passes through. The first ends of a pair of insulated wires are respectively connected to the corresponding connection terminals in the housing 111 of the connection portion 11. A pair of insulated wires is connected to the outer end 140 of the connecting cable 14 and the rotating body 1230, and the second end of the pair is connected to the corresponding terminal plate 1211 of the connecting member 121.

In the suspension type electric appliance 100 of this modification, by rotating the rotating body 1230 to the first support body 1231 and the second support body 1232, the connection in the plane (in the horizontal plane) orthogonal to the suspension direction can be adjusted Position of the Department 11. That is, the position of the functional part 22 of the second unit 20 connected to the connection part 11 can be adjusted in a plane (in a horizontal plane) orthogonal to the hanging direction.

In the suspension type electric appliance 100 of this modification, as shown in FIG. 11, the first unit side cable 13 may be further provided. In this case, the first unit side cable 13 is provided between the second end 142 of the connection cable 14 and the connection portion 11. The first end 131 of the first unit-side cable 13 is connected to the connection portion 11. The second end 132 is connected to the second end 142 of the connection cable 14. For example, the first unit side cable 13 is a part of the insulated wire that passes through the outer contour 140 of the connection cable 14. The insulated wire passes through the outer profile 140. The wires of the insulated wires are electrically insulated by the sheath and the outer profile 140. In this case, the position of the functional part 22 of the second unit 20 connected to the connection part 11 can also be adjusted in a plane (in a horizontal plane) orthogonal to the suspension direction. In addition, the dotted hatched arrows in FIG. 11 indicate the turning of the rotating body 1230. However, the rotation range of the rotating body 1230 is not limited to the range of the dotted hatched arrow, and it can be rotated at any angle around the axis of the rotating body 1230 (that is, the rotating range of the rotating body 1230 is 360°). The first unit-side cable 13 may have an outer shape as with the connection cable 14, and may also have a length adjustment mechanism (first outer shape, second outer shape, and fixture).

In this modification, the lateral rotation member 123 may be provided with a temporary position fixing mechanism (gear mechanism, such as a ratchet mechanism) that can fix the rotation of the rotating body 1230 at a predetermined angular interval (e.g., 5° interval) position.

(3.6) Sixth modification

With reference to Fig. 12, a suspended electrical appliance 100 according to a sixth modification will be described. The suspension-type electric appliance 100 of this modification is different from the suspension-type electric appliance 100 of the basic example in the configuration of the main mounting portion 12.

In the suspension type electric appliance 100 of this modification, the attachment portion 12 is provided with a winding member 124 instead of the cover member 122. The winding member 124 includes, for example, a housing 1241, a spool, a coil spring that is a spring, And release button 1242.

The housing 1241 is formed of, for example, a resin material, and has a cylindrical shape with a storage space 1240 inside. The housing 1241 is a part (upper part) of the side surface of the cylinder, and has a planar portion, and the connecting member 121 is connected to this portion. In addition, on the side surface of the cylindrical casing 1241, an insertion hole 1243 for passing the first unit-side cable 13 is formed in a portion away from the plane portion. The reel system is accommodated in the housing 1241. A portion of the first unit-side cable 13 on the side of the mounting portion 12 (the portion of the second end 132) is housed in the housing space 1240 of the housing 1241. It is accommodated so that it can be wound by a reel.

The reel uses a ratchet mechanism to restrict the direction of rotation so that only the first unit-side cable 13 can be drawn out. If the first unit-side cable 13 is pulled, the first unit-side cable 13 is drawn out from the housing space 1240 of the housing 1241. In addition, when the release button 1242 is operated with the first unit side cable 13 pulled out, the restriction by the ratchet mechanism is released, and the recovery force acting on the reel from the coil spring is applied, and the reel is wound in the direction of winding the first unit side cable 13 Turn.

That is, in the present modification, the mounting portion 12 has an accommodating space 1240 for accommodating and accommodating a part of the first unit-side cable 13 on the mounting portion 12 side.

According to this modification, a part of the first unit-side cable 13 on the mounting portion 12 side can be accommodated in the housing space 1240 of the casing 1241 of the winding member 124. Therefore, when the functional unit 22 is not used, the length of the first unit-side cable 13 can be shortened, and when the functional unit 22 (second unit 20) is not used, it is possible to further reduce the restriction of the movement of the suspended electrical appliance 100 to people Range of possibilities.

In this modification, the reel, the coil spring, and the release button (and the ratchet mechanism and the storage space) may be provided in the connection portion 11, or may be provided in the input portion 21 or the function portion 22 (socket body 220 ).

(3.7) Seventh modification

With reference to Fig. 13, a suspension type electric appliance 100 according to a seventh modification will be described. The suspension-type electric appliance 100 of this modification is different in the configuration of the main mounting portion 12 and the first unit-side cable 13, and is different from the suspension-type electric appliance 100 of the basic example in further including the holding body 9.

As shown in FIG. 13, in this modification, the first unit-side cable 13 has an outer profile 130.

The outer profile 130 is a metal tube such as stainless steel, and the surface is coated with an insulating synthetic resin. The outline 130 is cylindrical. The outer profile 130 has rigidity of a predetermined value or more. For example, the outer profile 130 has a rigidity that does not bend when the first unit 10 is held by the holding body 9. The outer profile 130 is better in bending rigidity and torsional rigidity. The insulated wire including the wire and the sheath passes through the outer profile 130. The wires of the insulated wires are electrically insulated by the sheath and the outer profile 130.

The attachment portion 12 includes an arm member 125 instead of the cover member 122.

The arm member 125 includes a first arm 1251, a second arm 1252, an arm-side cable 1253, a first spring 1254, and a second spring 1255.

The first arm 1251 is formed of, for example, a metal material. The first arm 1251 is formed by a pair of side plates (first arm side plate) and a top plate, and is formed as an inverted U shape on the side. The top plate is a rectangular plate with a hole drilled in the center for passing the arm-side cable 1253. It is joined to the lower surface of the cylindrical body 1210 (see FIG. 3) of the connection member 121. The pair of side plates is a semi-circular rectangular plate whose front ends are protruded in the thickness direction of the top plate so as to face each other. Insertion holes (first insertion holes) are formed in the front end portions of the pair of side plates, respectively. At the base end portions (top plate side portions) of the pair of side plates, semi-circular plate-shaped support plate portions are formed to protrude in the width direction of the side plates, respectively. Further, from the support plate portion, cylindrical hook portions (first hook portions) protrude outward.

The second arm 1252 is formed of, for example, a metal material. The second arm 1252 is formed by a pair of side plates (second arm side plate) and a bottom plate, and is formed as a U-shape on the side. The bottom plate is in the shape of a rectangular plate, and the lower surface is joined to the second end 132 of the first unit side cable 13, and the insulated wire of the first unit side cable 13 passes through the hole formed in the center thereof. The pair of side plates is a semi-circular rectangular plate whose front ends are protruded in the thickness direction of the bottom plate so as to face each other. At the front end portions of the pair of side plates, insertion holes (second insertion holes) are formed, respectively. From the base end portions (bottom plate side portions) of the pair of side plates, cylindrical hook portions (second hook portions) protrude outward.

The arm-side cable 1253 is a part of the above-mentioned insulated wire. A pair of power cables of the arm-side cable 1253 are respectively connected to the corresponding terminal boards 1211 in the cylindrical body 1210 of the connection member 121.

The first arm side plate and the second arm side plate overlap the first and second insertion holes, and pass the bushing through the first and second insertion holes, and the bolts are coupled to the nut through the bushing. The centers of the 1st and 2nd penetration holes can be relatively rotated as a rotation axis. That is, the arm member 125 can be transferred between the first state (refer to the two-dot chain line in FIG. 13) and the second state (refer to the solid line in FIG. 13), and the first state is the length direction of the first arm 1251 versus The longitudinal direction of the second arm 1252 coincides, and the second state is that the longitudinal direction of the first arm 1251 crosses the longitudinal direction of the second arm 1252. By the turning of the arm member 125 to the second arm 1252 of the first arm 1251, the protruding direction of the pair of protruding portions 1212 of the connecting member 121 (the protruding direction of the pair of terminal plates 1211) is used as the direction of the rotation axis. That is, the arm member 125 constitutes a longitudinal rotation mechanism that holds the first unit-side cable 13 in a posture along the vertical direction of the first unit-side cable 13 (refer to the two-dot chain line in FIG. 13) and along It can rotate between the horizontal posture (refer to the solid line in FIG. 13).

Each of the first spring 1254 and the second spring 1255 is a coil spring (tension coil spring). Each of the first spring 1254 and the second spring 1255 is hooked at one end by the first hook portion of the first arm side plate, and at the other end by the second hook portion of the second arm side plate. The natural lengths of the first spring 1254 and the second spring 1255 are substantially the same as the interval between the first hook portion and the second hook portion when the arm member 125 is in the second state.

The first spring 1254 and the second spring 1255 are elongated when the arm member 125 transitions from the second state to the first state by widening the interval between the first hook portion and the second hook portion. In addition, the first spring 1254 and the second spring 1255 use the restoring force generated by being stretched to decelerate the transition speed of the arm member 125 from the second state to the first state. That is, in the present embodiment, the first spring 1254 and the second spring 1255 constitute the reduction mechanism. The so-called deceleration mechanism here is a mechanism that decelerates the rotation speed of the first unit-side cable 13 when the first unit 10 is rotated from the posture in the horizontal direction to the posture in the vertical direction by the vertical rotation mechanism (arm member 125).
