An open relationship of an aspect of the present invention includes the switch handle and the switch body. ‌

The following embodiments relate to a switch handle and a switch, and more particularly to a switch handle that is attached to the switch body so as to cover the front surface of the switch body, and a switch including the switch handle.

(1) Overview The switch handle 10 of the present embodiment includes a handle body 1, a door portion 3, a light guiding member 6, and a display portion (lens 7) as shown in Fig. 1 .

The handle body 1 is attached to the switch body 9 so as to cover the front surface 91 (refer to FIG. 2) of the switch body 9 (refer to FIG. 2). The handle body 1 is a window portion 11 having at least a part of light transmissive.

The door portion 3 is attached to the handle body 1 so as to rotate between a closed position covering the rear surface 111 of the window portion 11 (refer to FIG. 3) and an open position at which the rear surface 111 of the window portion 11 is not covered.

‌ The light guiding member 6 has a first end 61 and a second end 62 which are both ends in a predetermined direction. The light guiding member 6 is disposed between the handle body 1 and the switch body 9 such that at least a portion of the window portion 11 is positioned between the first end 61 and the second end 62 in the predetermined direction. The light guiding member 6 is in a state where the door portion 3 is at the closed position, and the light incident on the rear surface 611 (refer to FIG. 3) of the first end 61 is emitted from the front surface 621 of the second end 62.

‌ The display unit is provided at a portion of the handle body 1 corresponding to the second end 62. The display unit emits light emitted from the front surface 621 of the second end 62 toward the front from the front surface 13 of the handle body 1.

Here, the door portion 3 may cover at least a part of the rear surface 111 of the window portion 11 in the closed position, and it is not necessary to completely cover the rear surface 111 of the hidden window portion 11.

That is, in the switch handle 10, light from the light-emitting portion provided in the switch body 9 can be guided from the first end 61 rear surface 611 to the second end 62 front surface 621 by the light guiding member 6. Here, at least a portion of the window portion 11 is positioned between the first end 61 and the second end 62 in the specified direction. In short, the light guiding member 6 straddles at least a part of the window portion 11 and guides light from the light emitting portion provided in the switch body 9 toward the display portion of the switch handle 10. Therefore, even if the light-emitting portion of the switch body 9 is provided on the same side as the bearing portion 143 (refer to FIG. 3) of the front surface 91 of the switch body 9, the display portion can be disposed on the opposite side of the bearing portion 143 with the door portion 3 interposed therebetween. Therefore, when the user presses the switch handle 10, the one end portion of the handle body 1 on the same side as the display portion with respect to the door portion 3 can be pressed to perform an intuitive operation.

Further, the switch 100 of the present embodiment includes the switch handle 10 and the switch body 9 as shown in Fig. 2 . The switch handle 10 is attached to the front surface 91 side of the switch body 9 so as to cover the front surface 91 of the switch body 9.

The switch body 9 has a button handle 92 on the front face 91. Further, the switch body 9 has a shaft portion 93 at one end portion of the front surface 91. The switch handle 10 is attached to the shaft portion 93 so as to be rotatable about the shaft portion 93 as a center. As a result, when the switch handle 10 is pressed, the switch handle 10 is rotated about the shaft portion 93, and the switch handle 10 is pressed into the rear by the switch handle 10. The term "pressing operation" as used herein refers to an operation of pressing the end portion opposite to the shaft portion 93 of the switch knob 10 to the rear. That is, the switch handle 10 is a piano handle for pressing the button handle 92.

Further, in the state in which the switch handle 10 and the door portion 3 are in the closed position, there is a label for accommodating the name tag 51 between the rear surface 111 of the translucent window portion 11 and the front surface 31 of the door portion 3. Storage space 5 (refer to Figure 5A). The nameplate 51 is a label or seal made of, for example, paper or synthetic resin. In the brand name 51, information (load name, place name, etc.) for finding the circuit corresponding to the switch body 9 is marked as needed, for example, "living room", "porch lighting", or "door light". In the present embodiment, the name tag 51 is not included in the components of the switch handle 10, but the name tag 51 can be included in the components of the switch handle 10.

所谓 "Translucent" as used herein means light transmissive or transparent, that is, a property that at least transmits visible light. In particular, in order to clearly recognize the information marked on the brand name 51 through the window portion 11, the material of the window portion 11 is preferably a transparent property which is less likely to cause diffusion of the transmitted light.

‌ In order to allow the name tag 51 to enter and exit the label storage space 5, the door portion 3 must be in the open position. However, when the switch handle 10 is attached to the switch body 9, it is difficult to move the door portion 3 to the open position. In other words, the entry and exit of the brand name 51 into the label storage space 5 is performed in a state where the switch handle 10 is not attached to the switch body 9.

That is, by having the switch handle 10 with the window portion 11 and the door portion 3, the name tag 51 can be attached to the switch handle 10 to mark the information for finding the corresponding circuit. Therefore, there is an advantage that the user can easily find the switch handle 10 and the switch 100 of the corresponding circuit. In the following description, the switch handle 10 is attached to the switch body 9 and the door portion 3 is in the closed position, unless otherwise specified.

‌ (2) Details ‌ The following description will be given assuming that the switch 100 is used in a wall of a building such as a house. Hereinafter, unless otherwise specified, the switch 100 that is attached to the wall will be defined as upper, lower, left, and right when viewed from the front, and each direction is defined as upper, lower, left, and right. In addition, the direction orthogonal to the wall surface is referred to as the front-rear direction, and the direction in which the front surface 91 of the switch body 9 faces is referred to as the front. That is to say, in the first figure, etc., as indicated by the arrows "upper", "down", "left", "right", "front" and "rear", the upper, lower, left, right, front, After all directions. However, these directions are not meant to specify the direction of use of the switch handle 10 and the switch 100. In other words, the front surface 91 of the switch body 9 does not have to face forward. For example, the switch 100 may be attached to the ceiling, and the front surface 91 of the switch body 9 may be used downward. Further, the arrows indicating the respective directions in the drawings are labeled for the sake of explanation, and are not accompanied by entities.

In particular, the width of the depression on the front surface of the thin portion 42 is larger than the rear surface of the thin portion 42. When the door portion 3 moves between the closed position and the open position, the thin portion 42 is deformed. Therefore, the door portion 3 rotates around the hinge portion 4, and particularly rotates around the thin portion 42. As shown in FIG. 4, the through hole 41 is inserted into the press-fitting portion 148 on the lower side of the pair of press-fitting portions 148, and the front end portion (rear end portion) of the press-fitting portion 148 protrudes rearward from the rear surface of the hinge portion 4.

The hinge portion 4 is integrally formed with the fixing member 2 and the door portion 3. In the present embodiment, the fixing member 2, the door portion 3, and the hinge portion 4 constituting the frame member 20 are made of the same material. The frame member 20 is made of synthetic resin and is made of a non-rigid plastic such as polypropylene or a semi-rigid plastic. Therefore, the frame member 20 is softer than the handle body 1 composed of a rigid plastic. That is, the fixing member 2, the door portion 3, and the hinge portion 4 are both softer than the support member 14 and the cover member 15 constituting the handle body 1. In other words, both the support member 14 and the cover member 15 are harder than the fixed member 2, the door portion 3, and the hinge portion 4.

The so-called "hard plastic", "semi-rigid plastic" and "soft plastic" are in accordance with the requirements of "JIS K6900". That is to say, "hard plastic" is a plastic having a bending elastic modulus under specified conditions or a tensile modulus of elasticity greater than 700 MPa when not applicable. "Semi-rigid plastic" is a plastic having the same bending modulus or tensile modulus of elasticity between 70 MPa and 700 MPa. "Soft plastic" is a plastic having the same flexural modulus or tensile modulus of elasticity greater than 70 MPa.

The ‌ lens 7 is made of synthetic resin and has light transmissivity. Here, the lens 7 is a transparent crucible made of, for example, an acrylic resin. The lens 7 has a flange portion 71 and an insertion portion 72. The flange portion 71 is integrally formed with the insertion portion 72. The flange portion 71 has an elongated circular plate shape in which the vertical direction is longer than the horizontal direction. The insertion portion 72 has a shape that protrudes forward from a central portion in the vertical direction of the front surface of the flange portion 71. The insertion portion 72 has an elliptical shape similar to that of the through hole 16 in plan view. The lens 7 is attached to the handle body 1 by fixing the flange portion 71 around the through hole 16 of the rear surface 12 of the handle body 1. In a state where the lens 7 is attached to the handle body 1, the insertion portion 72 is inserted into the through hole 16. As a result, from the front surface 13 of the handle body 1, the front surface of the lens 7 is exposed. A plurality of grooves extending in the up and down direction are formed on the front surface of the lens 7. Further, a plurality of grooves extending in the left-right direction are formed on the rear surface of the lens 7. As a result, the light that is incident on the front surface of the lens 7 and then emitted from the front surface of the lens 7 is diffused.

‌ The light guiding member 6 is made of synthetic resin and has light transmissivity. Here, the light guiding member 6 is made of, for example, an acrylic resin, and is a transparent crucible. The light guiding member 6 has a first end 61 and a second end 62 which are both ends in a predetermined direction. Further, the light guiding member 6 has an intermediate portion 63 that connects the first end 61 and the second end 62. The first end 61, the second end 62, and the intermediate portion 63 are integrally formed. The intermediate portion 63 has a rectangular plate shape in which the left-right direction is longer than the vertical direction. In the present embodiment, the designated direction is the left-right direction, and the first end 61 and the second end 62 are positioned on both sides of the intermediate portion 63 in the left-right direction. The light guiding member 6 has a shape in which the first end 61 protrudes rearward from the intermediate portion 63. Further, the dimension of the second end 62 in the vertical direction is larger than that of the intermediate portion 63. Further, on the front surface 621 of the second end 62, a protruding portion 64 that protrudes forward is formed.

‌ The light guiding member 6 is fixed to the rear surface 32 of the door portion 3. Specifically, the light guiding member 6 is attached to the holding groove 33 by the intermediate portion 63 and is attached to the door portion 3. A plurality of attachment claws 65 project from the portions of the both sides of the intermediate portion 63 in the upper and lower directions corresponding to the plurality of side grooves 34. The intermediate portion 63 is held in the holding groove 33 by fastening a plurality of mounting claws 65 to the plurality of holding claws 35 (refer to Fig. 5A). In this manner, the light guiding member 6 is disposed between the handle body 1 and the switch body 9 such that at least a part of the window portion 11 is positioned between the first end 61 and the second end 62 in the left-right direction. The second end 62 protrudes from the holding groove 33 toward the right, and the front surface 621 of the second end 62 is disposed on the right side of the door portion 3 in the opening portion 21.

In the ‌ light guiding member 6, the third protruding portion 612 that protrudes in the vertical direction is provided at the end portion on the distal end portion 37 side in the vertical direction, that is, the upper end portion. The third protrusion 612 has a shape that protrudes upward from the first end 61 . Similarly to the first protrusion 38, the third protrusion 612 is a protrusion that the operator buckles the finger when the operator moves the door unit 3 from the closed position to the open position.

‌ The light guiding member 6 emits light incident on the rear surface 611 of the first end 61 from the front surface 621 of the second end 62. The rear surface 611 of the first end 61 faces the front surface of the light-emitting portion of the switch body 9 (the front surface of the light cover 95). The front surface 621 of the second end 62 is opposed to the rear surface of the lens 7. Therefore, when the light-emitting portion of the switch body 9 emits light, the light emitted from the switch body 9 is guided to the lens 7 by the light guiding member 6. Therefore, light from the light-emitting portion of the switch body 9 is emitted forward from the front surface of the lens 7, so that the light-emitting state of the light-emitting portion of the switch body 9 can be recognized from the front of the handle body 1. Therefore, the lens 7 functions as a display portion. The display unit is provided in a portion corresponding to the second end 62 of the handle body 1 and is a portion that emits light emitted from the front surface 621 of the second end 62 from the front surface 13 of the handle body 1 toward the front.

In the present embodiment, the plurality of attachment claws 65 are integrally formed with the first end 61, the second end 62, the intermediate portion 63, and the protruding portion 64. However, the plurality of mounting claws 65 do not contribute to the original function of the light guiding member 6, that is, the light incident from the rear surface 611 of the first end 61 is emitted from the front surface 621 of the second end 62. Therefore, the plurality of mounting claws 65 are not included in the constituent elements of the light guiding member 6.

Further, it is preferable that the switch handle 10 is provided with a light shielding member that is provided between the light guiding member 6 and the window portion 11 and that is shielded from light. In the present embodiment, the frame member 20 is made of an opaque material in which a pigment is mixed. Therefore, the door portion 3 of the frame member 20 between the light guiding member 6 and the window portion 11 serves as a light shielding member. The door portion 3 completely covers a portion of the light guiding member 6 (excluding the plurality of mounting claws 65) facing the rear surface 111 of the window portion 11. Therefore, the light leaking from the light guiding member 6 is blocked by the door portion 3 as the light shielding member, and light leakage toward the front surface 13 side of the handle body 1 via the window portion 11 is suppressed.

Next, the rotation operation of the door portion 3 of the switch handle 10 will be described with reference to FIGS. 5A, 5B, and 6.

状态 In a state where the door portion 3 is in the closed position, as shown in FIG. 5A, the label storage space 5 exists between the rear surface 111 of the window portion 11 and the front surface 31 of the door portion 3. The name tag 51 is accommodated in the label storage space 5. The name plate 51 is held in the label storage space 5 in a state of being held between the rear surface 111 of the window portion 11 and the front surface 31 of the door portion 3. In this state, the switch handle 10 is attached to the switch body 9. Therefore, when the switch handle 10 is attached to the switch 100 of the switch body 9, the information marked by the nameplate 51 behind the window portion 11 can be recognized from the front of the window portion 11.

When the operator moves the door portion 3 from the closed position to the open position, when the switch handle 10 is not attached to the switch body 9, the operator holds the finger to the first protrusion 38 or the light guiding member of the door portion 3. The third projection 612 of 6 pulls the front end portion 37 of the door portion 3 from the rear. As a result, the thin portion 42 of the hinge portion 4 is deformed, and the door portion 3 is rotated by the base end portion 36 as a fulcrum, and the door portion 3 is moved from the closed position to the (rotated) open position. In the state in which the door portion 3 is in the open position, as shown in Fig. 5B, the label storage space 5 becomes a space opened later. Therefore, when the switch handle 10 is detached from the switch body 9, and the door portion 3 is in the open position, the name tag 51 can enter and exit the label storage space 5.

‌ Further, in a state where the door portion 3 is in the open position, the plurality of temporary holding projections 147 provided on the inner circumferential surface of the recess 146 are tightly held around the brand name 51, and the name plate 5 is temporarily held in the recess. Within 146. Therefore, the operator can set the name plate 51 in the label storage space 5 in a state where the door portion 3 is opened, and the workability of the installation name plate 51 can be improved. Further, since the door portion 3 is rotated at the fulcrum at the lower end portion (base end portion 36), the door portion 3 is positioned below the recess 146 in a state where the door portion 3 is at the open position. Therefore, when the brand name 51 enters and exits the label storage space 5, the operator can use the front surface 31 of the door portion 3 as a guide to allow the name card 51 to enter and exit, thereby improving workability.

时 When the operator moves the door portion 3 from the open position to the closed position, when the switch handle 10 is not attached to the switch body 9, the operator presses the front end portion 37 of the door portion 3 forward. As a result, the thin portion 42 of the hinge portion 4 is deformed, and the door portion 3 is rotated by the base end portion 36 as a fulcrum, and the door portion 3 is moved (rotated) from the open position to the closed position. At this time, as the door portion 3 rotates, the second projection 39 contacts the contact surface 17 of the handle body 1, and the door portion 3 further rotates, and then, as shown in Fig. 6, the second projection 39 is pressed to the contact surface. 17. As a result, the long hole 311 and the portion of the second protrusion 39 are elastically deformed. Therefore, in a state where the door portion 3 is in the closed position, the second projection 39 is pressed against the contact surface 17, and the frictional force between the second projection 39 and the contact surface 17 is increased. As a result, the door portion 3 is held in the closed position by the so-called snap-fit configuration.

Further, when the door portion 3 is moved (rotated), the light guiding member 6 fixed to the rear surface 32 of the door portion 3 also moves together with the door portion 3. Here, the longitudinal direction of the light guiding member 6, that is, the predetermined direction in which the first end 61 and the second end 62 of the light guiding member 6 are arranged side by side, and the radial direction when the door portion 3 is rotated, that is, the base of the door portion 3 The predetermined direction in which the end portion 36 and the front end portion 37 are arranged side by side is orthogonal to each other. In short, in the present embodiment, since the designated direction is the horizontal direction and the predetermined direction is the vertical direction, the designated direction and the predetermined direction are orthogonal to each other. Therefore, when the door portion 3 is rotated, the first end 61 and the second end 62 of the light guiding member 6 fixed to the rear surface 32 of the door portion 3 are moved in a direction away from the handle body 1. Therefore, the light guide member 6 can rotate the door portion 3 without hindering the movement of the handle body 1. The term "orthogonal" as used herein is not only a state of 90 degree intersection under strict definition, but also a state of being substantially orthogonal within a certain range of errors.

2.3 (2.3) Internal structure of the switch body Next, the structure inside the body 94 of the switch body 9 (the internal structure of the switch body 9) will be described with reference to Fig. 7.

开关 The switch body 9 is provided with a resistor 904, a diode 905, and a current transformer 906 in addition to the contact 901, the first light source 902, and the second light source 903. Each of the first light source 902 and the second light source 903 is an LED (Light Emitting Diode). The first light source 902 and the resistor 904 are electrically connected in series. The series circuit of the first light source 902 and the resistor 904 is connected to the contact 901 in electrical parallel. The primary winding system of the current transformer 906 is connected to the contacts 901 in electrical series. The second light source 903 and the diode 905 are electrically connected in parallel between the two ends of the secondary winding of the converter 906. The second light source 903 and the diode 905 are connected to each other in a reverse direction with respect to the secondary winding of the current transformer 906. The illuminating colors of the first light source 902 and the second light source 903 are different from each other. As an example, the illuminating color of the first light source 902 is white, and the illuminating color of the second light source 903 is red.

According to the above configuration, when the contact 901 is turned off, a current flows through the series circuit of the first light source 902 and the resistor 904, and the first light source 902 is turned on, and the light-emitting portion of the switch body 9 emits light in white. Further, when the contact 901 is turned on, the current flows through the second light source 903, and the second light source 903 is turned on, so that the light-emitting portion of the switch body 9 emits light in red. In other words, the lighting state of the first light source 902 or the second light source 903 is changed by the energization state of the load, and the light-emitting state (for example, the luminescent color) of the light-emitting portion of the switch body 9 is changed.

2.4 (2.4) Mounting Structure of Switch ‌ Next, an example of a structure for mounting the switch 100 to a wall (an attachment structure of the switch 100) will be described with reference to FIG. Fig. 8 shows a state in which three switches 100 of the same configuration are arranged side by side in the vertical direction.

‌ The switch 100 is mounted to the wall using the mounting frame 81 as described above. The flat frame 82 and the flat cover 83 are attached to the mounting frame 81. That is, the mounting structure of the switch 100 includes a mounting frame 81, a flat frame 82, and a flat cover 83.

‌ The mounting frame 81 is made of synthetic resin or metal. The mounting frame 81 is in the shape of a rectangular frame having a mounting hole 811. The mounting hole 811 has a rectangular shape in which the vertical direction is longer than the horizontal direction. The shape and size of the mounting hole 811 are substantially the same as those of the front surface 91 of the three switch bodies 9 when the three switch bodies 9 are arranged in the vertical direction.

‌ In the mounting frame 81, hanging holes 812 are formed in the mounting frame 81 at positions on both sides in the left-right direction of the mounting hole 811 for holding the switch body 9. As a result, the switch body 9 is attached to the mounting hole 811 of the mounting frame 81, and the hanging claws 97 are fitted into the hanging holes 812, and are held by the mounting frame 81.

‌ In the mounting frame 81, fixing holes 813 are formed in the both sides of the mounting hole 811 in the vertical direction, and the screws for fixing the respective mounting frames 81 to the wall are passed. Further, a screw hole 814 is formed on the side opposite to the mounting hole 811 with respect to each of the fixing holes 813 for fixing the plate frame 82 to the mounting frame 81.

平板 The plate frame 82 is made of synthetic resin. The plate frame 82 has a rectangular frame shape having a first opening hole 821. In the flat frame 82, through holes 822 are formed in the both sides of the first opening hole 821 in the vertical direction, and the screws for fixing the respective flat frames 82 to the mounting frame 81 are passed. In the plate frame 82, holes 823 are formed in the both sides of the first opening hole 821 in the left-right direction for fixing the respective flat cover bodies 83 to the flat frame 82.

平板 The flat cover 83 is made of synthetic resin. The flat lid body 83 has a rectangular frame shape having a second opening hole 831. The flat cover 83 is attached to the flat frame 82 so as to cover the front surface of the flat frame 82. On the rear surface of the flat lid body 83, a hanging protrusion that protrudes rearward is formed. The flat cover body 83 is held by the flat frame 82 by the hanging protrusion being fastened around the hole 823 of the flat frame 82.

安装 With the above-described mounting structure of the switch 100, the mounting frame 81 holding the state of the switch body 9 is fixed to the wall, and the switch 100 is mounted on the wall. In a state where the switch 100 is mounted on the wall, at least a part of the switch body 9 is buried in the wall, and the front surface 91 of the switch body 9 is exposed forward from the mounting hole 811 of the mounting frame 81. The switch handle 10 attached to the switch body 9 is exposed forward from the second opening hole 831 of the flat lid body 83.

(3) Advantages The switch handle 10 of the present embodiment described above includes the handle body 1, the fixing member 2, the door portion 3, and the hinge portion 4. The handle body 1 is attached to the switch body 9 in such a manner as to cover the front surface 91 of the switch body 9. The handle body 1 is attached to at least a portion of the window portion 11 having light transmissivity. The fixing member 2 is fixed to the rear face 12 of the handle body 1. The hinge portion 4 is integrally formed with the fixing member 2 and the door portion 3. The hinge portion 4 connects the door portion 3 to the fixing member 2 such that the door portion 3 can rotate between the closed position and the open position. The closed position is the position at which the door portion 3 covers the rear surface 111 of the window portion 11. The open position door portion 3 does not cover the position of the rear surface 111 of the window portion 11.

According to this configuration, the door portion 3 rotatable between the closed position of the rear surface 111 of the cover window portion 11 and the open position of the rear surface 111 of the window portion 11 is joined to the fixing member 2 by the hinge portion 4. Here, the fixing member 2, the door portion 3, and the hinge portion 4 are integrally formed. In short, the door portion 3 is rotatable to the fixing member 2 by the joint fixing member 2 and the hinge portion 4 of the door portion 3 being deformed. Therefore, even if a slight dimensional error occurs in the switch handle 10, the handle body 1 is less likely to be deviated from the door portion 3 than the structure in which the shaft body is fitted into the bearing portion, so that the door portion 3 is less likely to be shaken relative to the handle body 1. As a result, there is an advantage that the switch handle 10 having improved quality can be obtained even if the door portion 3 is provided.

Further, as in the present embodiment, the handle body 1 preferably has the support member 14 and the lid member 15. The support member 14 has a window hole 141 and is mounted on the switch body 9. The cover member 15 has a light-transmissive portion covering the window hole 141 and is disposed in front of the support member 14. At this time, it is preferable that the support member 14 is attached to the rear surface 12 of the handle body 1 and the window hole 141 is fastened to the window portion 11. According to this configuration, the handle body 1 has the two members of the support member 14 and the cover member 15, and therefore a part of the handle body 1 can be made of a different material. However, the handle body 1 has the necessary structure in which the support member 14 and the cover member 15 are not the switch handle 10, and the handle body 1 can also be constituted by one member.

Further, as in the present embodiment, in the state in which the door portion 3 is in the closed position, it is preferable that the label storage space 5 exists between the rear surface 111 of the window portion 11 and the front surface 31 of the door portion 3. According to this configuration, the name plate 51 can be stored in the label storage space 5 in a state where the door portion 3 is in the closed position. However, the presence of the label storage space 5 is not an essential configuration of the switch handle 10, and the label storage space 5 may not exist.

Further, as in the present embodiment, the door portion 3 is preferably a base end portion 36 and a front end portion 37 which are both end portions in a predetermined direction. At this time, the hinge portion 4 is provided at the proximal end portion 36 of the door portion 3, and the distal end portion 37 of the door portion 3 is provided with a projection portion (first projection portion 38) that protrudes away from the proximal end portion 36. good. According to this configuration, when the operator moves the door portion 3 from the closed position to the open position, the operator can hold the first projection 38 with the hand to simplify the operation of opening the door portion 3. However, the first protrusions 38 are not necessary structures of the switch handle 10, and the first protrusions 38 may be omitted.

Further, the switch 100 of the present embodiment includes the switch handle 10 and the switch body 9. According to this configuration, there is an advantage that the switch 100 having improved quality can be obtained even if the switch 100 is provided with the door portion 3.

Further, the switch handle 10 of the present embodiment includes a handle body 1, a door portion 3, a light guiding member 6, and a display portion (lens 7). The handle body 1 is attached to the switch body 9 in such a manner as to cover the front surface 91 of the switch body 9. The handle body 1 is attached to at least a portion of the window portion 11 having light transmissivity. The door portion 3 is attached to the handle body 1 so as to be rotatable between a closed position covering the rear surface 111 of the window portion 11 and an open position not covering the rear surface 111 of the window portion 11. The light guiding member 6 has a first end 61 and a second end 62 which are both ends in a predetermined direction. The light guiding member 6 is disposed between the handle body 1 and the switch body 9 such that at least a part of the window portion 11 is located between the first end 61 and the second end 62 in a predetermined direction. The light guiding member 6 is in a state where the door portion 3 is at the closed position, and the light incident on the surface 611 after the first end 61 is emitted from the front surface 621 of the second end 62. The display unit is provided at a portion of the handle body 1 corresponding to the second end 62. The display unit emits light emitted from the front surface 621 of the second end 62 toward the front from the front surface 13 of the handle body 1.

According to this configuration, since the switch handle 10 has the window portion 11 and the door portion 3, the name tag 51 for identifying the relevant information of the corresponding circuit can be attached to the switch handle 10. Therefore, there is an advantage that the switch handle 10 for the corresponding circuit can be easily found by the user. Further, in the switch handle 10, light from the light-emitting portion provided in the switch body 9 can be guided from the first end 61 rear surface 611 to the second end 62 front surface 621 by the light guiding member 6. Here, at least a part of the window portion 11 is located between the first end 61 and the second end 62 in the specified direction. In short, the light guiding member 6 straddles at least a part of the window portion 11 and guides light from the light emitting portion provided in the switch body 9 to the display portion of the switch handle 10. Therefore, even if the light-emitting portion of the switch body 9 is provided on the same side as the bearing portion 143 of the front surface 91 of the switch body 9, the display portion can be disposed on the opposite side of the bearing portion 143 with the door portion 3 interposed therebetween. Therefore, when the user presses the switch handle 10, the one end portion of the handle body 1 facing the door portion 3 on the same side as the display portion can be pressed, and the intuitive operation can be performed. As a result, there is an advantage that the switch handle 10 that is easy to perform an intuitive operation can be obtained even if the door portion 3 is provided.

Further, as in the present embodiment, it is preferable that the front surface 621 of the second end 62 is formed with a protruding portion 64 that protrudes forward. According to this configuration, the gap between the front surface 621 and the display portion (lens 7) is smaller than the amount of the protruding portion 64, and light leakage between the front surface 621 of the second end 62 and the display portion is suppressed. However, the protruding portion 64 is not an essential configuration of the switch handle 10, and the protruding portion 64 can be omitted.

Further, as in the present embodiment, the light guiding member 6 is preferably fixed to the rear surface 32 of the door portion 3 in a state where the door portion 3 is at the closed position. According to this configuration, the door portion 3 is moved together with the light guiding member 6, so that the door portion 3 and the light guiding member 6 can be prevented from obstructing each other. Further, when the name plate 51 is taken in and out with the door portion 3 in the open position, the light guiding member 6 is less likely to be hindered. However, the light guide member 6 is fixed to the rear surface 32 of the door portion 3 not to the necessary configuration of the switch handle 10, and the light guide member 6 can also be fixed to the rear surface 32 of the door portion 3.

Further, as in the present embodiment, the door portion 3 has a light-shielding property, and the door portion 3 is located at a closed position, and can cover a portion of the light guiding member 6 that faces the rear surface 111 of the window portion 11. According to this configuration, light leaking from the light guiding member 6 is blocked at the door portion 3, and light leakage through the window portion 11 toward the front surface 13 side of the handle body 1 is suppressed. However, the door portion 3 has a light-shielding property which is not necessary for the switch handle 10, and the door portion 3 may have light transmissivity.

Further, as in the present embodiment, the door portion 3 has the base end portion 36 and the tip end portion 37 which are both end portions in the predetermined direction, and is preferably rotated about the base end portion 36 between the closed position and the open position. At this time, it is preferable that the end portion on the distal end portion 37 side in the predetermined direction of the light guiding member 6 is provided with a protruding portion (third protruding portion 612) that protrudes in a predetermined direction. According to this configuration, when the operator moves the door portion 3 from the closed position to the open position, the operator can buckle the third protruding portion 612 with the finger, and the work of opening the door portion 3 can be simplified. However, the third protrusion 612 is not an essential structure of the switch handle 10, and the third protrusion 612 can be omitted.

Further, as in the present embodiment, it is preferable that the designated direction and the predetermined direction are orthogonal to each other. According to this configuration, when the door portion 3 is rotated, the light guiding member 6 fixed to the rear surface 32 of the door portion 3 moves both the first end 61 and the second end 62 away from the handle body 1. Therefore, the light guiding member 6 does not obstruct the handle body 1, and the door portion 3 can be rotated. However, the specified direction and the prescribed direction are orthogonal to each other not to the necessary configuration of the switch handle 10, and the designated direction and the prescribed direction may not be orthogonal to each other.

Further, the switch 100 of the present embodiment includes the switch handle 10 and the switch body 9. According to this configuration, there is an advantage that the switch 100 which is easy for the user to find the corresponding circuit can be obtained.

Further, the switch handle 10 of the present embodiment includes a handle body 1, a fixing member 2, a door portion 3, and a hinge portion 4. The handle body 1 is attached to the switch body 9 in such a manner as to cover the front surface 91 of the switch body 9. The handle body 1 is attached to at least a portion of the window portion 11 having light transmissivity. The fixing member 2 has an opening portion 21 and is fixed to the rear surface 12 of the handle body 1 in such a manner that the window portion 11 is exposed from the opening portion 21. The hinge portion 4 connects the door portion 3 to the fixing member 2 such that the door portion 3 can rotate between the closed position and the open position. The closed position is the position at which the door portion 3 covers the rear surface 111 of the window portion 11. The open position is a position at which the door portion 3 does not cover the rear surface 111 of the window portion 11. The fixing member 2 is softer than the handle body 1.

According to this configuration, the door portion 3 is not directly attached to the handle body 1, but is attached to the handle body 1 via the hinge portion 4 and the fixing member 2. The fixing member 2 is fixed to the rear surface 12 of the handle body 1 so that the window portion 11 is exposed from the opening portion 21, so that the handle body 1 can be fixed to a relatively wide range around the window portion 11. Moreover, since the fixing member 2 is softer than the handle body 1, a slight dimensional error of the fixing member 2 can be absorbed by the deformation of the fixing member 2. Therefore, even if a dimensional error occurs in the fixing member 2, the reduction in the mounting strength of the fixing member 2 with respect to the handle body 1 can be suppressed. Therefore, there is an advantage that the mounting strength of the door portion 3 to the handle body 1 is increased in the switch handle 10.

Further, as in the present embodiment, the fixing member 2, the door portion 3 and the hinge portion 4 are integrally formed, and the hinge portion 4 is preferably softer than the handle body 1 and has a thin portion 42 which is thinner than the fixing member 2. According to this configuration, the door portion 3 is less likely to be displaced from the fixing member 2, and therefore the mounting strength of the door portion 3 to the handle body 1 is further increased. Further, when the thin portion 42 of the hinge portion 4 is deformed, the door portion 3 moves between the closed position and the open position, so that the door portion 3 is less likely to be loosened with respect to the handle body 1. However, the hinge portion 4 is softer than the handle body 1 and is not an essential configuration of the switch handle 10, and the hinge portion 4 may not be softer than the handle body 1.

Further, as in the present embodiment, the door portion 3 is preferably softer than the handle body 1. According to this configuration, in a state where the door portion 3 is in the closed position, a part (the second projection 39) of the door portion 3 is pressed to a part (contact surface 17) of the handle body 1, and the door is engaged by the fastening structure. The part 3 will be kept in the closed position. That is, since the door portion 3 is softer than the handle body 1, the door portion 3 and the handle body 1 for realizing the fastening structure have a margin in dimensional accuracy. Further, by adopting the fastening structure, the bonding force between the door portion 3 and the handle body 1 can be secured to a certain level or more, and the durability of the repeated opening and closing of the door portion 3 can be improved. However, the door portion 3 is softer than the handle body 1 and is not an essential configuration of the switch handle 10, and the door portion 3 can be softer than the handle body 1.

Further, as in the present embodiment, the switch handle 10 further includes the light guide member 6 and the display portion (lens 7), and the light guide member 6 is fixed to the door portion 3 in a state where the door portion 3 is in the closed position. Face 32 is preferred. According to this configuration, the door portion 3 moves together with the light guiding member 6, so that interference of the door portion 3 with the light guiding member 6 can be avoided. In particular, the fixing member 2, the door portion 3 and the hinge portion 4 are integrally formed, and when the fixing member 2, the door portion 3, and the hinge portion 4 are softer than the handle body 1, the door portion 3 is in the closed position, and the guide portion 3 is guided. The optical member 6 is less likely to cause a positional deviation with respect to the display portion. That is to say, at this time, since the door portion 3 is less likely to be loosened to the handle body 1, the light guide member 6 is less likely to be displaced from the display portion.

Further, as in the present embodiment, the fixing member 2 is fixed to the rear surface 12 of the handle body 1 by three or more joint portions 149 provided on the rear surface 12 of the handle body 1, and three or more joint portions 149 It is better to configure them not on the line side by side. According to this configuration, the fixing member 2 is fixed to the rear surface 12 of the handle body 1 by the joint portion 149 which is dispersedly disposed in a plurality of directions along the rear surface 12 of the handle body 1, so that the door portion 3 is attached to the handle body 1 The installation strength will be further improved. In the present embodiment, the fixing member 2 is fixed to the rear surface 12 of the handle body 1 by a plurality of coupling portions 149 which are arranged in the two directions of the left-right direction and the vertical direction. Therefore, the fixing member 2 is in the left-right direction and the vertical direction. The direction is not easy to loosen. However, the plurality of joint portions 149 are not juxtaposed in a straight line and are not necessary structures for the switch handle 10, and the plurality of joint portions 149 may be juxtaposed in a straight line.

Further, the switch 100 of the present embodiment includes the switch handle 10 and the switch body 9. According to this configuration, there is an advantage that the mounting strength of the door portion 3 to the handle body 1 is improved at the switch 100.

(4) Modifications The above-described embodiments can be variously modified in accordance with the design and the like as long as the scope of the technical idea of the present invention is not exceeded. That is, the present invention is not limited to the above embodiment.

Hereinafter, a modification of the above embodiment will be listed.

The switch 100 is not limited to a piano handle switch, and may be, for example, a rocker type (rocker type) switch. Further, the switch 100 is not limited to a single switch, and may be, for example, a three-way switch or a four-way switch.

Further, the switch body 9 is not limited to a structure in which the light-emitting state of the light-emitting portion of the switch body 9 is changed in accordance with the opening/closing of the contact 901, and the light-emitting portion of the switch body 9 may be illuminated according to the operating state of the load. The construction of state changes. For example, when the load is a dimmable lighting fixture, the lighting state of the light-emitting portion of the switch body 9 can be changed according to the degree of dimming of the lighting fixture. Alternatively, the switch body 9 may have a configuration in which only one light source is provided, and the light source is alternately turned on/off according to the on/off of the contact 901.

Further, the switch handle 10 is not limited to the case where the three switch bodies 9 are mounted on one mounting frame 81, that is, for the so-called three-way switch. For example, a case where one switch body 9 is used in one mounting frame 81, that is, a single-way switch, or two switch bodies 9 are mounted in one mounting frame 81, that is, for double Road switch. In the case of the one-way switch, the size of the switch handle 10 for the three-way switch as exemplified in the above-described embodiment is substantially three times. In the case of the two-way switch, the size of the switch handle 10 for the three-way switch as exemplified in the above embodiment is about 3/2 times.

Further, the door portion 3 and the light guiding member 6 may be integrally formed. In other words, the door portion 3 can also function as the light guiding member 6. According to this configuration, the number of parts is reduced as compared with the case where the door portion 3 and the light guiding member 6 are separated.

Further, the switch handle 10 can be disposed between the light guiding member 6 and the window portion 11 and additionally provided with a light blocking member that blocks light. The light shielding member is, for example, a synthetic resin sheet having a light blocking property. In short, in addition to the door portion 3, a light shielding member may be additionally provided. According to this configuration, similarly to the case where the door portion 3 functions as a light blocking member, the light leaking from the light guiding member 6 is blocked by the light blocking member, and the passage of the window portion 11 toward the front surface 13 side of the handle body 1 is suppressed. Light leaks. At this time, the door portion 3 may not have a light blocking property.

Further, the longitudinal direction of the light guiding member 6, that is, the specified direction in which the first end 61 and the second end 62 of the light guiding member 6 are arranged in parallel, and the radial direction when the door portion 3 is rotated, that is, the base of the door portion 3 The predetermined direction in which the end portion 36 and the front end portion 37 are juxtaposed may be the same direction. For example, the specified direction and the specified direction may both be left and right directions. At this time, the both end portions in the left-right direction of the door portion 3 serve as the base end portion 36 and the front end portion 37. The hinge portion 4 is a portion that connects one end portion (base end portion 36) of the door portion 3 in the left-right direction and one of the left and right directions of the opening portion 21 of the fixing member 2.

Further, the rear surface 611 of the first end 61 may be parallel to the front surface of the light-emitting body 95, which is the front surface of the light-emitting portion of the switch body 9, and may be inclined to the front surface of the light cover 95. The front surface 621 of the second end 62 may not be parallel to the rear surface of the lens 7, but may be inclined to the rear surface of the lens 7.

Further, the lens 7 can be omitted. At this time, the through hole 16 of the handle body 1 functions as a display portion. In other words, the light emitted from the front surface 621 of the second end 62 passes through the through hole 16 and is emitted from the front surface 13 of the handle main body 1 toward the front.

Further, the light guiding member 6 can be directly fixed to, for example, the rear surface of the fixing member 2 or the rear surface 12 of the handle body 1, instead of the rear surface 32 of the door portion 3. At this time, even if the door portion 3 moves (rotates), the light guiding member 6 does not move.

Further, the fixing member 2 may not be softer than the handle body 1. For example, the fixing member 2 and the handle body 1 may both be hard plastic or semi-rigid plastic. Alternatively, the fixing member 2 may be harder than the handle body 1.

Further, the fixing member 2 is not limited to the frame shape having the opening portion 21, and may be, for example, a rectangular plate shape. At this time, the fixing member 2 is fixed around the window portion 11 of the rear surface 12 of the handle body 1.

Further, the hinge portion 4 may not be integrally formed with the fixing member 2 and the door portion 3. For example, the door portion 3 may be directly attached to the handle body 1. At this time, the door portion 3 is rotatably attached to the handle body 1 by, for example, the hinge portion 4 or the bearing structure. Alternatively, the hinge portion 4, the fixing member 2, and the door portion 3 having the same shape as the above embodiment can be configured by other members.
