[Figure 6] This is the second assembly drawing of the light-emitting element unit. [Figure 7] FIG. [Figure 8] FIG. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0010] As shown in Figure 1, the guide wand of the present invention has a long cylindrical rod-shaped main body 1 with a light-emitting unit 2 on one side and a grip unit 3 on the other side. The overall length is approximately 54 cm, and the outer diameter of the light-emitting unit 2 and grip unit 3 is approximately 4 cm. Between the light-emitting unit 2 and grip unit 3 is an operation unit 10 with a slightly larger outer diameter and an operation button 11. Each time the operation button 11 is pressed, the light-emitting unit 2 switches between flashing, constant light, and off. The outer surface of the grip unit 3 has numerous projections and recesses 31 that fit comfortably in the hand. A hand strap 33 to be worn around the wrist of the guide is tied to a protrusion 32 at the end of the grip unit 3.

[0011] As shown in Fig. 2, the light-emitting unit 2 has a transparent or semi-transparent cylinder 21 with translucency, and a lid 22 that covers the tip. A large number of projections and recesses 23 are provided along the vertical direction on the inner wall surface of the cylinder 21 to enhance the reflective effect. A red highly reflective sheet 24 is wrapped around and in contact with the inner wall surface of the cylinder 21, causing the light-emitting unit 2 to emit red light.

[0012] 3 and 4, the operation unit 10, located on the opposite side of the operation button 11, is provided with a charging port 5 for charging the rechargeable battery 4 built into the grip 3. The charging port 5 is made of a connector compliant with USB (Universal Serial Bus), and as a particularly preferred example, a connector compliant with USB Type C is used. This connector is capable of connecting a plug compliant with USB Type C, and a terminal board 55 is provided inside the connection recess 50 thereof so that the plug can be connected even if it is upside down.

[0013] The charging port 5 is normally closed by a cover body 6 made of an elastic material such as rubber when not charging. The cover body 6 integrates a circular flat portion 61 that makes planar contact with the circular connector outer surface 51 around the connection recess 50, a horizontally elongated cylindrical protrusion 62 that protrudes into the connection recess 50, an attachment portion 65 having a slender connecting arm 63 and a circular ring-shaped fixing portion 64 that are attached to the operation portion 10 of the main body 1, and an operation piece 66 that is operated by a finger. Under normal circumstances, the protrusion 62 protrudes into the connection recess 50 to surround the terminal board 55 in an annular shape, and the flat portion 61 is in close contact with the connector outer surface 51, thereby doubly preventing the intrusion of rainwater and dust into the terminal board 55.

[0014] 5 and 6, the light-emitting element unit 7 built into the light-emitting section 2 has a light-emitting element group 73 formed by soldering a plurality of, for example, six LEDs 70 in parallel to an anode (+) side conductor 71 and a cathode (-) side conductor 72. The light-emitting element group 73 is housed inside a package case 8 made of a transparent material. This case 8 has a first case 81 and a second case 82 that are connected with a slit 80 in between at the central folded-back portion.

[0015] The LEDs 70 are housed in a dome-shaped recess 84 that forms six LED storage spaces 83 when the first case 81 and the second case 82 are butted together. The conductive wires 71, 72 are housed in a vertical recess 86 that forms two cylindrical vertical spaces 85 when butted together. The ends of the lead wires of the LEDs 70 are housed in a horizontal recess 88 that forms six cylindrical horizontal spaces 87 when butted together. The first case 81 is provided with a rectangular recess 89, and the second case 82 is provided with a rectangular protrusion 90 that protrudes into the rectangular recess 89.

[0016] The butted end of the first case 81 has multiple sets of parallel cuts 91, 91, and the butted end of the second case 82 has multiple sets of lug cuts 92, 92 that turn the lug portions from the parallel cuts 91, 91 to the back side of the first case 81. A quadrangular pyramid-shaped bracing portion 93 is provided between the upper and lower dome-shaped recesses 84 of each case 81, 82. When assembled, the left and right end portions of each case 81, 82 and the tip portions of each bracing portion 93 are close to the inner wall of the cylinder 21 of the light-emitting unit 2, cushioning the impact on the light-emitting element group 73 while allowing uniform and good light emission to the outside of the cylinder 21.

[0017] As shown in FIG. 7, the rechargeable battery 4 is, for example, a 3.7V, 1200mAh lithium ion battery. When fully charged, the continuous lighting time during flashing is expected to be about 11 to 12 hours, and the continuous lighting time during normal lighting is expected to be about 9 to 10 hours. The length and outer diameter of the battery 4 are small, about half the length and inner diameter of the grip 3. This leaves a large gap above the lower reinforcing rib 34 inside the grip 3. Therefore, a flanged bush 40 made of an elastic material such as rubber is inserted, the battery 4 is received in a center hole 41 of the bush 40, and the flange 42 of the bush 40 is pushed against the ribs 35 radially provided on the inner wall of the grip 3, thereby supporting the battery 4.

[0018] The screw portion 36 at the end of the grip portion 3 is screwed into the screw portion 12 of the operating portion 10. 37 denotes a ring-shaped elastically deformable member. When the screw portion 36 is screwed in, the positive lead wire 43 and the negative lead wire 44 attached to the battery 4 may be twisted and broken. For this reason, the outside of the positive lead wire 43 is covered with a tube 45 that is flexible and can reduce frictional force, and before the grip portion 3 is screwed in, the positive lead wire 43 and the negative lead wire 44 covered with the tube 45 are wound in the opposite direction to prevent excessive stress from being applied to the leads 43, 44 when the grip portion 3 is screwed in.

[0019] In addition, the + side lead wire 43, the - side lead wire 44, and the tube 45 are made somewhat longer, and when the grip portion 3 is screwed in, the leads 43, 44 and the tube 45 are tightly stored inside the grip portion 3 at the top of the battery 4, and together with the support provided by the flanged bushing 40, the battery 4 can be held stably.

[0020] A disk-shaped base 94 for mounting parts is positioned on a step 13 provided continuous with the screw portion 12 of the operating unit 10. A pin 95 integrated with the upper surface of the base 94 is inserted into a lower cylinder 15 integrated with a partition plate 14 provided on the inner wall of the operating unit 10 that receives the lower end of the light-emitting unit 2, and a claw portion 96 provided on the radially outer side of the base 94 is engaged with a recess 16 provided near the step 13.

[0021] A switch holder 97 and a board holder 98 are integrated into the base 94. The switch holder 97 supports a push button switch 99 that is operated by pressing the operation button 11. The operation button 11 is made of an elastic material and has a large outer diameter before and after clamping the mounting hole 17 of the operation part 10 to prevent the intrusion of rainwater and dust. The board holder 98 supports an LED lighting control board 100 that supplies a pulse voltage to the conductors 71, 72 of the light-emitting element unit 7 when the light is flashing, supplies a continuous voltage when the light is constantly lit, and supplies no voltage when the light is off.

[0022] Charging port 5, which is made up of a connector conforming to USB Type-C, uses a molded part 59 with leads, which is made by connecting a wedge-shaped main body 58 with fine irregularities 57 on its outer periphery to a flange 56 that forms a circular connector outer surface 51 at its end face. This molded part 59 is attached to the inner wall of the operation unit 10 with an adhesive or the like. On an LED lighting control board 100, the battery 4, the push button switch 98, and each of the leads of the molded part 59 of the charging port 5, as well as leads that connect to conductors 71 and 72, are connected.

[0023] The screwed portion between grip portion 3 and operating portion 10, the mating portion between light-emitting portion 2 and operating portion 10, and the mating portion between cylinder 21 and cover 22 in the light-emitting portion are fixed with adhesive to make the structure unable to be disassembled, thereby reliably preventing the intrusion of rainwater and dust into the interior.

[0024] As shown in FIG. 8, when charging, for example, a direct-plug charger 102 having a connector 101 conforming to USB Type A and a conversion cable 103 between USB Type C and USB Type A are prepared. The charging port 5 is opened by releasing the closure by the cover body 6, and the C-side plug 104 of the conversion cable 103 is inserted into the charging port 5. The A-side plug 105 of the conversion cable 103 is inserted into the connector 101 of the charger 102, and the charger 102 is inserted into an indoor power distribution outlet such as 100V AC. During charging, a small circular display 106 provided on the connector outer surface 51 of the charging port 5 is lit red by an LED embedded inside the molded product 59. When charging is completed, the display 106 turns green.

[0025] Charging is also possible from devices with a USB port, such as a computer. A USB Type C to USB Type B conversion cable, a USB Type C to USB Type C connection cable, etc. can also be used. The charging port 5 itself can use USB Type B or USB Type A, etc.

[0026] As described above, the induction rod of this invention has a total weight of 186g, making it lighter than ever before. [Explanation of symbols]
