Further, as shown in FIGS. 2 and 8, a pull switch 140 is arranged in the main body 110. A wire 150 made of stainless steel is attached to the pull switch 140, and a pull string 160 is attached to the tip of the wire 150. The wire 150 and the drawstring 160 form a string-like body 170 as a whole (FIG. 10). The string-like body 170 may be composed of the wire 150 and the pull string 160, may be composed of only the wire 150, or may be composed of only the pull string 160. When it comprises only a wire, the part of the drawstring edge part 162 from the wire side connection part 151 in FIG. 8 is a wire. In the case of only the drawstring 160, the portion from the wire side connecting portion 151 to the drawstring end 162 in FIG. 8 is the drawstring.

  As shown in FIG. 8, the instrument body 100 includes a recess 111 having a flat plate portion 112, a first side wall portion 113-1, and a second side wall portion 113-2. The flat plate portion 112 has a flat plate shape having a long shape. The first side wall portion 113-1 has a flat plate shape that rises from one end portion 115-1 (FIG. 5) along the longitudinal direction of the flat plate portion 112 in a substantially vertical direction and has a through hole 113H. The second side wall portion 113-2 has a flat plate shape that rises in a substantially vertical direction from the other end portion 115-2 (FIG. 2) along the longitudinal direction of the flat plate portion 112. As shown in FIGS. 4 and 8, the main body 110 includes a first inclined portion 114-1 and a second inclined portion 114-2 that reflect light emitted from the light source unit 200. The concave portion 111 is sandwiched between these inclined portions. The inclined portion 114-1 is formed with an inclined portion through hole 114H through which the string-like body 170 passes.

  As shown in FIG. 4 and FIG. 8, the concave portion 111 is composed of a flat plate portion 112 forming a bottom surface portion, a first side wall portion 113-1 and a second side wall portion 113-2, and has a U-shaped cross section. , A portion formed over the longitudinal range 118. The main body 110 shown in FIG. 4 is formed by bending a single plate, but may be formed by a plurality of plates. A through hole 113H (FIGS. 5 and 8) is formed in the first side wall portion 113-1. Further, as shown in FIG. 8, a convex portion 180 is formed on the flat plate portion 112 so as to protrude outward from the concave portion 111. The convex portions 180 are formed, for example, on the upper side of the right spring portion 130 and the upper side of the left spring portion 130 in FIG.

  A bush 500 is inserted into the through hole 113H. The bush 500 is made of a resin such as nylon, polybutylene terephthalate, or polycarbonate.

  As shown in FIG. 5, the through-hole 113H has a circular shape partially cut into a convex shape 113H-1, and the bush main body 510 also has a bush convex portion that engages with the convex shape 113H-1. 540 (FIG. 6). The engagement between the convex shape 113H-1 and the bush convex portion 540 prevents the bush main body portion 510 from rotating. In other words, the outer shape of the bush main body 510 is a shape in which at least a part that fits into the through hole 113 </ b> H has a circular shape and has a bush convex portion 540.

  As shown in FIG. 8, the pull switch 140 is housed in the recess 111. The pull switch 140 is connected to the pull switch main body 141, which is a case attached to the flat plate portion 112, the rotary switch 142 provided inside the pull switch main body 141, and the rotary switch 142. And a rod-like pulling portion 143 pulled from the outside. The pulling portion 143 is, for example, a metal rod. The pulling portion 143 is pulled in the pulling direction 144 from the second side wall portion 113-2 toward the first side wall portion 113-1. When the pulling portion 143 is pulled in the pulling direction 144, the pulling portion 143 moves so as to protrude from the pull switch main body portion 141 substantially in parallel with the flat plate portion 112. As shown in FIG. 8, a ring-shaped pulling side end 143 a is formed at the end of the pulling portion 143. The pull switch 140 switches the power supply state to the light source unit 200 when the pulling portion 143 is pulled in the pulling direction 144. Specifically, every time the pulling portion 143 is pulled, the rotary switch 142 included in the pull switch 140 is switched between an on state and an off state. The rotary switch 142 supplies power from the power supply device 270 (FIG. 3) to the light source unit 200 in the on state, and cuts off power supply from the power supply device 270 to the light source unit 200 in the off state. As shown in FIG. 9, in the pull switch 140, when the pull portion 143 is pulled so as to be switched on and off, a part including the pull side end portion 143a of the pull portion 143 protrudes from the through hole 113H. The flat plate portion 112 is disposed so as to be stored in the storage space 511 of the bush 500.

  As shown in FIG. 8, the wire 150 passes through the bush 500 from the inside of the recess 111 toward the outside 700, and the portion immediately after passing through the wire 150 is bent as a wire bent portion 153. The wire bent portion 153 is formed by bending in an L shape, and has wire side connecting portions 151 and 152 at both ends. After passing through the bush 500, the wire 150 extends in the X direction in FIG. 8, which is the direction in which the first side wall portion 113-1 rises. One side of the wire 150 is inserted into the inclined portion through-hole 114 </ b> H with the wire bent portion 153 as a boundary, and the other side is inserted into the bush 500. The wire-side connecting portion 151 is attached to the pull-side end portion 143a of the pulling portion 143 of the pull switch 140, and the wire-side connecting portion 152 is attached to the pulling-string end portion 161 of the pulling cord 160. Note that both ends of the wire 150 are bent and the tip is crimped to form a ring shape, and the ring-shaped portions formed in the ring shape form the wire side connecting portions 151 and 152.

  FIG. 10 shows the drawstring 160. The drawstring 160 is tied so that the drawstring end portion 161 on one end side forms a loop (FIG. 10A), and the drawstring end portion 162 on the other end side is a knob for pulling by the user. It has a portion 162a. The drawstring end portion 161 (ring) of the drawstring 160 is passed through the wire side connecting portion 152 (FIG. 10B), and then the knob portion 162a is passed through the looped portion of the drawstring end portion 161. The drawstring 160 is attached to the wire side connecting portion 152 (FIG. 10C).

  The light source unit 200 has a long shape and is attached to the recess 111. FIG. 12 is a simplified diagram for illustrating the assembly relationship of the light source unit 200 having a long shape. FIG. 12 is a view showing an end portion of the light source unit 200, and is a view showing a state in which the light source lid portion 240 (FIG. 3) at the end portion is removed. The light source unit 200 includes an attachment member 220 formed by being bent into a U-shape, an LED module 210 attached to the attachment member 220, and a translucent cover 230 attached to the attachment member 220 so as to cover the LED module 210. Prepare. Further, as illustrated in FIG. 3, the light source unit 200 includes a power supply device 270 that is attached to the attachment member 220 and supplies power to the LED module 210.

  The bush 500 will be described with reference to FIGS. As shown in FIG. 5, the bush 500 is disposed in the through hole 113 </ b> H formed in the first side wall portion 113-1. As shown in FIG. 9, the bush 500 is formed with a storage space 511 that stores a part of the pulling portion 143 pulled in the pulling direction 144. Further, the bush 500 is formed with a through space 512 following the storage space 511 so that the string-like body 170 having one end connected to the pulling portion 143 of the pull switch 140 passes from the storage space 511 to the outside 700. . Further, as shown in FIG. 9, in the relationship between the tension portion 143 and the through hole 113H, the through hole 113H is formed larger than the tension side end portion 143a so that the tension side end portion 143a of the tension portion 143 penetrates. ing. When the pulling portion 143 is pulled in the pulling direction 144, the pulling side end portion 143a protrudes from the through hole 113H.

  As shown in FIGS. 6 to 8, the bush 500 includes a substantially cylindrical bush main body 510, a bush flange 520 formed in an opening portion of the storage space 511 in the bush main body 510, and the bush main body 510. Are provided with a pair of bush claw portions 530 formed in a pair. As shown in FIG. 5, the bush body 510 is inserted into the through hole 113 </ b> H so that the bush collar 520 is inside the recess 111, and the bush collar 520 and the bush claw 530 are the first side wall 113. -1 is sandwiched and fixed. When the bush main body 510 is inserted into the through hole 113H, the bush claw 530 shown in FIG. 7 is elastically deformed in the direction of the arrow and presses the edge of the through hole 113H with a restoring force.

  As shown in FIG. 9, the size of the cross section in the penetrating space 512 with the tensile direction 144 as the normal direction is smaller than the size of the cross section in the storage space 511 with the tensile direction 144 as the normal direction. In FIG. 9, the storage space 511 and the through space 512 are illustrated as being hollowed out in a cylindrical shape extending in the pulling direction 144, but are not limited to a cylindrical shape. The cross section of the storage space for storing the cover 143 so as to cover a part of the pull portion 143 when pulled may be an ellipse or a rectangle instead of a circle. In the following description, it is assumed that the storage space 511 and the through space 512 are cylindrical.

  The storage space 511 is a substantially cylindrical space having a diameter of φD, and stores a part of the pulling portion 143. The storage space 511 is stored so as to cover a part of the pulling portion 143 when it is pulled, and when the pulling portion 143 is shaken as shown in FIG. to bound. Moreover, it can prevent that the tension | pulling part 143 at the time of being pulled interferes with another member. Thus, the storage space 511 is a dedicated space for storing a part of the pulling portion 143 when pulled. The diameter φD of the storage space 511 is formed larger than the diameter φB of the through space 512 in order to store the tension side end portion 143a.

  The through space 512 is a space that is formed following the storage space 511 and has a substantially cylindrical shape with a diameter of φB. The through space 512 functions as a wire restricting portion that restricts the shake of the wire 150. The diameter φB of the through space 512 that restricts the shake of the wire 150 is smaller than the diameter φD of the storage space 511. The through space 512 is preferably present, but may be omitted. When there is no through space 512, the bush 500 has, for example, a cylindrical shape with an inner diameter φD in FIG. That is, the bush 500 only needs to have the storage space 511, and more preferably has the through space 512.

  The storage space 511 is disposed on the bush flange 520 side, and the through space 512 is disposed on the opposite side of the bush flange 520. The wire 150 is inserted through the through space 512. When the wire 150 is pulled by the pull string 160, the wire 150 moves substantially linearly in the pulling direction 144 along the inside of the through space 512. The through hole 512 has a diameter φB that is slightly larger than the diameter φA of the wire 150.

  As shown in FIG. 9, when the pull-side end portion 143a is pulled by the wire 150, a part of the pull portion 143 including the pull-side end portion 143a is a concave portion on the left side of the first side wall portion 113-1. It protrudes from the inside of 111 through the through-hole 113H to the exterior of the recessed part 111 which is the right side rather than the 1st side wall part 113-1. The protruding portion is stored in the storage space 511. The storage space 511 is disposed between the bush flange portion 520 and the through space 512. The inner diameter φD of the storage space 511 has a tension-side end portion 143a when the pulling portion 143 is pulled by the wire 150. Is large enough to intervene. Thus, the storage space 511 is retracted in the pulling direction 144 by the amount that the pulling portion 143 protrudes. As shown in FIG. 9, the relationship among the diameter φA of the wire 150, the diameter φB of the through space 512, the maximum width C of the pulling portion 143, and the diameter φD of the storage space 511 is φA <φB <C <φD. .

In the present embodiment, since the storage space 511 and the through space 512 are formed in the bush 500, when the pulling portion 143 of the pull switch 140 is pulled, the pulling side end portion 143a protrudes from the through hole 113H. The pull switch 140 may be disposed on the flat plate portion 112. That is, in FIG. 8, since there is a storage space 511 that covers the part of the pulling part 143 when it is pulled, the pull switch 140 can be disposed closer to the first side wall part 113-1. For this reason, the clearance gap W2 (FIG. 8) between the 2nd side wall part 113-2 and the pull switch 140 can be taken widely. Therefore, an F cable or the like that connects the illumination devices 1000 can be arranged in the wide gap W2.
Thus, in the pulling direction 144, the pull switch 140 has a gap W2 between the side surface on the concave portion 111 side of the second side wall portion 113-2 and the side surface 140-2 facing the side surface on the concave portion 111 side. The gap 111 between the side surface of the first side wall portion 113-1 on the concave portion 111 side and the gap W1 between the side surface 140-1 facing the side surface on the concave portion 111 side is stored in the concave portion 111 so as to be substantially the same or larger. The That is, in the cross section of FIG. 8, the gap W2 ≧ the gap W1.

  As for the outer shape or appearance of the bush main body 510 of the bush 500, a storage space 511 having a shape capable of retracting a part of the pulling portion 143 including the pulling side end portion 143a can be formed, and blurring of the wire 150 can be restricted. There is no limitation as long as the through space 512 can be formed. The outer shape or the outer appearance of the bush main body 510 may be an elliptical shape or a square shape, or may be a shape in which a part is cut out. The convex shape 113H-1 does not need to be formed as long as it is an oval shape, a square shape, or a shape in which a part is cut out.

  In addition, the storage space 511 and the through space 512 have different shapes in the above, but a part of the storage space 511 may also serve as the through space 512. For example, the storage space 511 may have a cylindrical shape, and the end portion in the pulling direction 144 may function as the through space 512.

  FIG. 13 is a cross-sectional view of the bush 500-1. As shown in FIG. 13, the bush 500 may have a so-called trumpet shape in which the opening on the front end side of the through space 512 is formed larger than the opening on the storage space 511 side and the inner side surface is inclined in a gentle arc shape. By making the trumpet shape, the contact between the wire 150 and the outlet of the through space 512 becomes smooth.

  15 to 16 are diagrams showing the bush 600. As shown in these drawings, the bush may be completed by combining two parts. FIG. 14 is a perspective view of the bush 600. FIG. 15 is an exploded perspective view of the bush 600. FIG. 16 is a cross-sectional view of the bush 600, which is the same as the end face of the second half bush 602. FIG. 17 is a cross-sectional view when the bush 600 is used, corresponding to FIG. As shown in FIG. 15, the bush 600 includes two parts obtained by equally dividing the bush 500 into two parts in the vertical direction, and a ring-shaped ring member 660. One part is the first half bush part 601 and the other part is the second half bush part 602. As shown in FIG. 17, the bush 600 includes a ring-shaped ring member 660 that allows the string-like body 170 to pass through the outlet 512-1 of the through-space 512 where the string-like body 170 exits from the penetration space 512 to the outside 700. Yes. The ring member 660 is made of SUS, iron, aluminum or the like. As shown in FIG. 15, the first half bush portion 601 has assembly claw portions 611 for assembly up and down, and the second half bush portion 602 engages with the upper and lower assembly claw portions 611. A claw receiving portion 621 is provided. Each assembly claw portion 611 engages with a corresponding claw receiving portion 621.

  In the bush 600, the wire 150 is passed through the ring member 660, and the first half bush portion 601 and the second half bush portion 602 are connected and combined with the wire 150 interposed therebetween, and are fitted into the through hole 113H. be able to. Therefore, the attachment work of the wire 150 becomes easy.

  Further, as shown in FIG. 17, a ring member 660 is disposed at the outlet 512-1 of the through space 512 where the wire 150 is pulled by the pulling string 160 and comes into contact. When the wire 150 moves, the ring member 660 can prevent the wire 150 from being caught by the connection boundary 651 (FIG. 14) between the first half bush portion 601 and the second half bush portion 602. Further, the ring member 660 can prevent the outlet 512-1 from being worn by rubbing the outlet 512-1 of the through space 512 by the wire 150. Further, as shown in FIGS. 14, 16, and 17, a notch 652 is formed in a direction directly below the outlet 512-1 of the bush 600, and the distance between the wire 150 and the boundary 651 is separated. For this reason, since the wire 150 contacts the end portion of the ring member 660 when moving, it is possible to prevent the end portion of the through space 512 of the bush 600 from being worn and to prevent the wire 150 from being caught in the boundary 651.

  FIG. 18 is a diagram of the bush 600 formed by two first half bush portions 601. As shown in FIG. 18, the first half bush portion 601 includes an assembly claw portion 611 and a claw receiving portion 621, and a bush 600 is formed by the ring member 660 and the two first half bush portions 601. May be. In this case, the bush 600 can be configured with only the first half bush portion 601 without using the second half bush portion 602.

  Further, FIG. 19 divides the bush 500 into two equal parts and does not constitute the bush 600 as the first half bush part 601 and the second half bush part 602, but the bush 500 is formed so that the boundary 651 is zigzag. A divided configuration is shown. By making the boundary line 651 zigzag, when the wire 150 is pulled in the X direction, the risk of the wire 150 being pinched by the boundary line 651 can be reduced. Or you may bisect a bush in a horizontal cross section like the boundary 651-1 shown with a broken line in FIG. In this case, since the boundary 651-1 does not exist in the X direction in which the wire 150 hangs down, there is no fear that the wire 150 is caught between the boundaries 651-1.

  Although the bush 600 configured by the half bush portion has been described as the configuration including the ring member 660, the bush 600 may not include the ring member 660. In that case, the end face of the half bush portion has a shape like the cross section of the bush 500 shown in FIG. Further, although the bush 500 is described as having a configuration in which the ring member 660 is not provided, the bush 500 may be provided with the ring member 660.
