[0007] Before any of the designs of the disclosure are explained in detail, it should be noted that the application of the disclosure is not limited to the design details and the arrangement of components set forth in the following description or illustrated in the following drawings. The disclosure is also possible in other designs and can be practiced or implemented in various ways. Detailed description

[0008] Fig. Figures 1 to 2 represent a portable lamp 100 with a base 104, a main body 108 rotatably coupled to the base 104, and a lamp head 112 rotatably coupled to the main body 108. The base 104 comprises a first end 116, a second end 120 opposite the first end 116, a longitudinal element 124 extending between the first end 116 and the second end 120, and a stand 128 extending radially outwards from the first end 116.

[0009] Although the illustrated device is a portable lamp with a lamp head, in other embodiments the device may also include other types of output heads. For example, the device may be a portable loudspeaker comprising a speaker head or a portable fan comprising a fan head. The speaker head or the fan head may be coupled to the main body 108 and / or the base 104 in a similar manner to the lamp head 112 and be movable relative to it, and may have similar profiles to the lamp head 112, but with different output elements (for example, loudspeaker, fan, etc.) instead of the lamps of the lamp head 112 and other components specific to the lamp head 112.In some embodiments, the device may be a combination device and include a combination head, such as a combination of fan and light head, a combination of loudspeaker and light head, or a combination of fan, loudspeaker and light head.

[0010] The main body 108 is formed by the first end 116 and the second end 120 and extends between the first end 116 and the second end 120. The main body 108 is designed to hold a power source 130 ( Fig. 12B). In the illustrated construction, the main body 108 defines a battery receptacle 131, which is configured to receive the power source 130. The main body 108 defines a central longitudinal axis A1 and is rotatably coupled to the base 104 at the first end 116 and the second end 120, such that the main body 108 rotates about the longitudinal axis A1. In the illustrated construction, the longitudinal axis A1 passes through the center of the battery receptacle 131. In the illustrated construction, the first end 116 and the second end 120 are concentric with the longitudinal axis A1. In other words, the first end 116 and the second end 120 are concentric with the battery receptacle 131. The main body 108 includes a projection 132, and the base 104 includes a recess 133 designed to receive the projection 132 when the main body 108 is in a folded position ( Fig. 15A to 16B). In the folded position, the main body 108 is aligned with the stand 128 ( Fig. 15A to 16B). The portable lamp 100 includes an end cap 134 that secures the base 104 to the main body 108. The main body 108 includes a wall 135 that contacts the base 104, so that the base 104 is located between the end cap 134 and the wall 135.

[0011] The luminaire head 112 is rotatably mounted on the main body 108 and is designed to pivot a luminaire axis A2. In the illustrated design, the luminaire axis A2 bisects the luminaire head 112 in a direction perpendicular to the longitudinal axis A1. The luminaire head 112 includes a light source 136, which is optionally powered by the power source 130. In the illustrated design, the light source 136 comprises light-emitting diodes (LEDs). The light source 136 is designed to illuminate an area with floodlighting. The luminaire head 112 includes an indicator light 140, a switch 144, and a switch 148. The indicator light 140, the switch 144, and the switch 148 are located on the rear of the luminaire head 112, opposite the light source 136.In the illustrated design, indicator 140 provides information about the power supply to the power source 130, switch 144 is a power switch configured to turn the light source 136 on and off, and switch 148 toggles between different modes of the light source 136 (for example, low, medium, and high). Together, indicator 140, switch 144, and switch 148 form a user interface.

[0012] In Fig. Figures 3 to 7 show the base 104 with the first end 116 and the second end 120. In the illustrated construction, the first end 116 is a circular collar designed to surround a section of the main body 108. The first end 116 is clamped between the main body 108 and the end cap 134 so that the first end 116 cannot slip off the main body 108. In the illustrated construction, the second end 120 is a circular collar designed to surround a section of the main body 108. The stand 128 extends from the circular collar of the first end 116. In other constructions, the stand 128 may extend from the circular collar of the second end 120. In the illustrated construction, the stand 128 and the circular collar are integrated or monolithic. In other designs, the stand 128 can be a separate component coupled to the circular collar.The stand 128 includes an end 150 with a receptacle 152.

[0013] The base 104 includes a hook 156, which is rotatably coupled to the main body 108. The hook 156 is also rotatable relative to the first end 116, the second end 120, and the longitudinal element 124 of the base 104. In the illustrated construction, the hook 156 includes a circular collar 160. Similar to the first end 116, the circular collar 160 is configured to surround a section of the main body 108. In the illustrated construction, the circular collar 160 is located closer to the first end 116 than to the second end 120. In particular, the circular collar 160 is situated between the first end 116 and the wall 135 of the main body 108 ( Fig. 1) arranged. The circular collar 160 is located between the first end 116 and the wall 135, so that the circular collar 160 cannot slip off the main body 108. The hook 156 extends radially outward from the circular collar 160. The hook 156 comprises a first bend 164 and a second bend 168. The first bend 164 is bent or angled relative to the circular collar 160. The second bend 168 is bent or angled with respect to the first bend 164. In the illustrated construction, the first bend 164 is a 90-degree bend and the second bend 168 is also a 90-degree bend. The hook 156 comprises an end 170 with a receptacle 172 corresponding to the receptacle 152. The receptacle 172 extends radially inwards in the direction of the longitudinal axis A1. In some designs, the hook 156 can be replaced by a different hook if a different hook shape is desired.To remove the hook 156, the end cap 134 is removed from the main body 108 and the base 104 is removed from the main body 108 so that the hook 156 can be replaced.

[0014] Fig. Figure 5 shows that the hook 156 can be rotated relative to the first end 116 and the second end 120. In particular, the hook 156 can be rotated about the longitudinal axis A1 in a first direction D1 and a second direction D2, the second direction D2 being opposite to the first direction D1. The receptacle 152 includes a magnet 176. In the illustrated construction, the magnet 176 is encased within one end of the receptacle 152.

[0015] Fig. Figure 6 represents the receptacle 172 of the hook 156, which engages in the receptacle 152 of the stand 128. The receptacle 172 includes a magnet 180, which engages in the magnet 176 of the receptacle 152, so that the hook 156 and the stand 128 are held in a closed position relative to each other (for example, relative movement between the hook 156 and the stand 128 is prevented). In the closed position, the receptacle 172 of the hook 156 is connected to the receptacle 152 of the stand 128 ( Fig. 4) In the closed position, the stand 128 and the hook 156 together form a closed ring.

[0016] In Fig. Figure 7 shows that the first end 116 is coupled to the longitudinal element 124 by a fastening element 182. The second end 120 and the longitudinal element 124 are a single piece (e.g., monolithic). In the illustrated construction, the first end 116 is fixed relative to the longitudinal element 124, so that the stand 128 does not move relative to the longitudinal element 124. In other constructions, the first end 116 and the longitudinal element 124 are a single piece (e.g., monolithic). In other constructions, the second end 120 is formed separately from the longitudinal element 124 and coupled to the longitudinal element 124 via a fastening element.

[0017] In Fig. Figure 7 shows the base 104, which comprises a magnet assembly 184. Specifically, the magnet assembly 184 is arranged within the longitudinal element 124. The magnet assembly 184 comprises a first metal plate 188 (for example, a steel plate), a second metal plate 192 (for example, a steel plate), a first magnet 196, and a second magnet 200. The first metal plate 188 abuts the first magnet 196. The second metal plate 192 abuts the second magnet 200. In other designs, the magnet assembly 184 comprises a single metal plate that abuts both the first magnet 196 and the second magnet 200. In the illustrated design, the first magnet 196 and the second magnet 200 are cast into the longitudinal element 124.In the illustrated construction, the first magnet 196 is located closer to the first end 116 than to the second end 120, and the second magnet 200 is located closer to the second end 120 than to the first end 116. The second magnet 200 is spaced from the first magnet 196 in a direction parallel to the longitudinal axis A1. The first steel plate 188 and the second steel plate 192 are coupled to the longitudinal element 124 via fasteners 204. The magnet assembly 184 is arranged between the first end 116 and the second end 120 of the longitudinal element 124. The base 104 includes recesses 208 and cushions 212 received in the recesses 208. In some constructions, the cushions 212 are made of an elastomer (e.g., rubber, neoprene, etc.). One cushion of cushion 212 is arranged between the first end 116 and the first magnet 196. Another cushion 212 is positioned between the second end 120 and the second magnet 200.The cushions 212 are designed to create an air gap G1 between the magnets 196, 200 and a workpiece 216. Thus, the magnets 196, 200 do not directly touch the workpiece 216. The magnet arrangement 184 is configured such that the portable lamp 100 can be coupled to a ferromagnetic material (for example, iron, nickel, cobalt).

[0018] Fig. Figure 8 depicts the magnet arrangement 184 as a bridge structure. The bridge structure uses two magnets (for example, magnets 196, 200) and a metal plate (for example, steel plates 188, 192) extending between them. As in Fig. As shown in Figure 7, the steel plates 188 and 192 are separated from each other. However, the steel plates 188 and 192 have the same effect as a single steel plate. The cushions 212 arranged near the magnets 196 and 200 define the air gap G1 between the magnets 196 and 200 and the workpiece 216.

[0019] Fig. Figure 9 represents a magnet arrangement 220, which is interchangeable with the magnet arrangement 184. In other words, the magnet arrangement 220 can be used in place of the magnet arrangement 184 in the longitudinal element 124. The magnet arrangement 220 is a sandwich construction. The magnet arrangement 220 comprises a first metal plate 224, a second metal plate 228, and a magnet 232 flanked by the metal plates 224 and 228.

[0020] Fig. Figure 10 illustrates the magnetic arrangement 184 (for example, bridge construction) and the magnetic arrangement 220 (for example, sandwich construction). In cases where there is no air gap between a workpiece, the magnetic arrangement 220 offers the greatest tensile force at approximately 70 lbf. The magnetic arrangement 184 offers approximately 55 lbf without an air gap. However, the tensile force of the magnetic arrangement 184 decreases less sharply with increasing air gap compared to the magnetic arrangement 220.

[0021] Fig. Figures 11A to 12B represent the lamp head 112 of the portable lamp 100, which defines a first length L1. The first length L1 is measured in a direction parallel to the longitudinal axis A1. The first length L1 can be between approximately 50 millimeters and approximately 100 millimeters. In the illustrated construction, the first length L1 is 78.6 millimeters. In some constructions, the first length L1 is less than 78.6 millimeters. In some constructions, the first length L1 is greater than 78.6 millimeters. The stand 128 defines a second length L2. The second length L2 is measured in a direction parallel to the lamp axis A2. In the illustrated construction, the length of the main body 108 and the lamp head 112 in the same direction as the lamp axis A2 is equal to the second length L2. The second length L2 can be between approximately 50 millimeters and 100 millimeters. In the illustrated construction, the second length L2 is approximately 72.5 millimeters.In other designs, the second length L2 is less than 72.5 millimeters. In other designs, the second length L2 is greater than 72.5 millimeters.

[0022] Fig. Figure 11B represents the portable light 100, in which the power source 130 (for example, a battery) is held in the main body 108. To remove the hook 156 and / or the battery 130, the end cap 134 is removed from the main body 108, allowing the battery 130 to be taken out of the main body 108. In other words, the end cap 134 is designed to optionally enclose the battery 130 within the main body 108. In the illustrated design, the power source 130 is a battery, which may be a rechargeable 4-volt power tool battery. The battery 130 may comprise one or more battery cells, which may have, for example, a lithium (Li), lithium-ion (Li-ion), or other lithium-based chemistry. For example, the battery cells can have lithium cobalt (Li-Co), lithium manganese (Li-Mn), spinel or Li-Mn nickel chemistry.In other designs, the battery cells can have nickel-cadmium, nickel-metal hydride, or lead-acid battery chemistry. In another design, the battery 130 can be a special battery that is (partially or completely) housed in the main body 108. The battery 130 is designed to supply power to the light source 136. In the illustrated design, the battery 130 is a single-cell battery. In the illustrated design, the battery 130 has a positive terminal and a negative terminal located at the same end of the longitudinal end of the battery 130. That is, the positive terminal and the negative terminal share one end of the battery 130. The battery 130 is mounted in the battery holder 131. In the illustrated design, the battery 130 is cylindrical and is therefore mounted longitudinally along the longitudinal axis A1.Battery 130 defines an axis that is aligned with the longitudinal axis A1 when battery 130 is inserted into battery receptacle 131. In other words, battery 130 is arranged concentrically in battery receptacle 131. As shown in . Fig. As shown in Figure 11B, the electrical connection between the battery 130 and the light source 136 extends through a rotary connection (for example, the projection 132) that couples the main body 108 to the lamp head 112.

[0023] Fig. Figure 11B shows that the portable lamp 100 comprises a printed circuit board 236 (PCB), a first terminal 240, a second terminal 244, and the light source 136. The PCB 236 is arranged in the main body 108 and oriented perpendicular to the longitudinal axis A1. The PCB 236 is arranged in the main body 108 closer to one end 248 of the main body 108 than to the wall 135 ( Fig. 16A). End 248 is located near the second end 120 of base 104. The first connector 240 and the second connector 244 are located at end 248. In the illustrated design, the first connector 240 is configured to supply power to PCB 236 and thus to battery 130, since PCB 236 is connected to battery 130. In the illustrated design, the first connector 240 is a USB-C connector. The second connector 244 is configured to supply power to PCB 236 and thus to battery 130. In the illustrated design, the second connector 244 is a USB power connector. In the illustrated design, the first connector 240 and the second connector 244 are of different formats (for example, USB-C and USB). In other designs, the first connector 240 and the second connector 244 have the same format.In some designs, the first terminal 240 is configured to receive power from an external source and supply power to the battery 130, and the second terminal 244 is configured to discharge power from the second terminal 244 supplied by the battery 130.

[0024] Fig. 12B represents the portable lamp 100, which includes a printed circuit board 252 (PCB). The PCB 252 is configured to receive power from the battery 130 and receives signals from the switches 144 and 148. The PCB 252 is configured to power the light source 136 ( Fig. 11B) to control.

[0025] Fig. Figure 13 depicts the portable lamp 100 in its folded position. In the folded position, the projection 132 of the main body 108 is positioned in the recess 133 of the base 104 such that the main body 108 is flush with the base 104. That is, the main body 108 does not project vertically beyond (i.e., above or below) the first and second ends 116, 120 of the base 104, as shown in Figure 13. Fig. 13 can be seen.

[0026] Fig. Figures 14A to 14B show that the main body 108 and the end cap 134 define a third length L3. The third length L3 is measured in a direction parallel to the longitudinal axis A1. The third length L3 is greater than the first length L1. The third length L3 is between approximately 75 millimeters and approximately 125 millimeters. In the illustrated construction, L3 is 115.5 millimeters. In some constructions, the third length L3 is less than 115.5 millimeters. In some constructions, the third length L3 is greater than 115.5 millimeters. The end cap 134 defines a fourth length L4 (or diameter). The fourth length L4 is measured in a direction perpendicular to the longitudinal axis A1. The fourth length L4 is between approximately 20 millimeters and approximately 40 millimeters. In the illustrated construction, the fourth length L4 is 33.5 millimeters. In other constructions, the fourth length L4 is less than 33.5 millimeters.In other designs, the fourth length L4 is greater than 33.5 millimeters.

[0027] Fig. Figures 15A to 16B represent the hook 156, which defines a fifth length L5 (or width). The fifth length L5 is measured at an outermost point of the hook 156 relative to the longitudinal axis A1 (for example, at a point of the bends 164, 168) in a direction perpendicular to the longitudinal axis A1 and perpendicular to the luminaire axis A2. The fifth length L5 is between approximately 10 millimeters and approximately 20 millimeters. In the illustrated construction, the fifth length L5 is approximately 14 millimeters. In other constructions, the fifth length L5 is less than 14 millimeters. In other constructions, the fifth length L5 is greater than 14 millimeters.

[0028] As in Fig. As shown in Figures 15A to 16B, PCB 252 is arranged between switches 144 and 148 and the light source 136. In the illustrated configuration, the light source 136 and PCB 252 are arranged parallel to each other. In other configurations, the light source 136 is arranged on top of PCB 252. As shown in Fig. As shown in Figure 16A, the portable lamp 100 can include a location 256 for the terminals 240 and 244. Location 256 is situated on the lamp head 112 closer to the second end 120 than to the first end 116. In other words, the terminals 240 and 244 can be located on the lamp head 112 and not at the end 248 of the main body 108.

[0029] Fig. 17 and Fig. Figure 18 shows that the hook 156 is movable about the longitudinal axis A1. The hook 156 is moved from a first position ( Fig. 1) in the first direction D1 around the longitudinal axis A1 into a second position ( Fig. 17) moved. The first position can also be referred to as the closed position. The second position can also be referred to as the open position. In the open position, the receptacle 172 of the hook 156 is arranged at an angle to the receptacle 152 of the stand 128 about the axis A1. In the open position, an external support 260 can be arranged between the stand 128 and the hook 156. The hook 156 can be moved in the second direction D2 about the longitudinal axis A1 from the open position ( Fig. 17) be moved into the closed position, with the external support 260 arranged in the closed ring ( Fig. 17). The magnets 176 of the receptacle 152 and the magnet 180 of the receptacle 172 hold the locking position until a user overcomes a force on the magnets 176, 180.

[0030] In Fig. Figures 19 to 21 show various movements of the portable light 100. Fig. Figure 19 shows that the hook 156 is rotatable about the longitudinal axis A1 in the first direction D1 and in the second direction D2. In the illustrated construction, the hook 156 can be rotated 360 degrees about the longitudinal axis A1. In other constructions, the hook 156 can be rotated less than 360 degrees about the longitudinal axis A1. Fig. Figure 20 shows that the main body 108 and the lamp head 112 are rotatable about the longitudinal axis A1 in the first direction D1 and the second direction D2. In the illustrated construction, the main body 108 can be rotated 270 degrees about the longitudinal axis A1. In other constructions, the main body 108 can be rotated about the longitudinal axis A1 by more or less than 270 degrees. Fig. Figure 21 shows that the lamp head 112 is rotated about the lamp axis A2 in a third direction D3 and a fourth direction D4, which is opposite to the third direction D3. In the illustrated design, the lamp head 112 can be rotated 330 degrees about the lamp axis A2. In other designs, the lamp head 112 can be rotated about the lamp axis A2 by more or less than 330 degrees. The main body 108 and the lamp head 112 are doubly articulated (for example, the main body 108 moves about the longitudinal axis A1 and the lamp head 112 about the lamp axis A2).

[0031] Fig. Figures 22 to 27 depict the portable light 100 in different locations. Fig. Figure 22 shows that a profile (for example, the lengths L1 to L5) of the portable light 100 is dimensioned so that it can be stored in a pocket 264 of the clothing. Fig. Figure 23 shows that the profile of the portable lamp 100 is dimensioned such that it can be accommodated in a cup holder 268. In the illustrated construction of the portable lamp 100, the connections 240, 244 are arranged at location 256 (for example, the lamp head 112). Fig. 24 represents the locked position of the portable light, such that a nail 272 is arranged in the closed ring. Fig. Figure 25 represents a ferromagnetic surface 276 and the portable lamp 100 coupled to the ferromagnetic surface 276. In the illustrated construction, the magnet arrangement 184 of the base 104 faces the ferromagnetic surface 276, so that the portable lamp 100 rests on the ferromagnetic surface 276. Fig. Figure 26 shows the portable light 100 coupled to a backpack 280. The portable light 100 is in the locked position, with a section of the backpack 280 arranged in the closed ring so that the portable light 100 is carried. Fig. Figure 27 shows the portable light coupled to a belt loop 284.

[0032] Fig. Figures 28 to 30 describe a further construction of a portable lamp 300. The portable lamp 300 comprises a base 304, a main body 308 rotatably coupled to the base 304, and a lamp head 312 rotatably coupled to the main body 308. The base 304 includes a first end 316, a second end 320 opposite the first end 316, a longitudinal element 324 extending between the first end 316 and the second end 320, and a carabiner hook 328 extending radially outward from the first end 316. The portable lamp 300 includes an attachment 330 coupled to the main body 308. The attachment 330 is mounted relative to the main body 308. The portable lamp 300 comprises the end cap 134, which is coupled to the main body 308. In the illustrated construction, the main body 308, the end cap 134, and the attachment 330 are made of a polymer.Specifically, the main body 308, the end cap 134, and the attachment 330 are made of PC+ABS JH960. The carabiner hook 328 is made of a metal (for example, zinc, aluminum, or steel). In the illustrated design, the carabiner hook 328 is made of Zamak 5.

[0033] The main body 308 is received by the first end 316 and the second end 320 and extends between the first end 316 and the second end 320. In the illustrated construction, the first end 316 and the second end 320 are U-shaped. The main body 308 is rotatably coupled to the base 304 at the first end 316 and at the second end 320, so that the main body 308 rotates about the longitudinal axis A1. In the illustrated construction, the first end 316 and the second end 320 are concentric with the longitudinal axis A1. The main body 308 is configured to hold the power source 130 ( Fig. 45). The main body 308 is located between the folded position ( Fig. 28), in which the carabiner hook 328 is aligned with the lamp head 312, and an offset position ( Fig. 29), in which the carabiner hook 328 is angularly offset relative to the lamp head 312 about the longitudinal axis A2, is movable. In the illustrated construction, the base 304 can be moved relative to the one in Fig. The lamp head 312 is rotatably mounted on the main body 308 and is designed to swivel a lamp axis A2 ( 28 ). Fig. 30). In the illustrated construction, the lamp head 312 can be rotated 120 degrees in the third direction D3 relative to the one in Fig. The main body 308 can be rotated to the position shown in Figure 28. In the illustrated construction, the lamp head 312 can be rotated 180 degrees in the fourth direction D4 relative to the position shown in Figure 28. Fig. The main body 308 can be rotated to the position shown in 28.

[0034] Fig. Figures 31 to 33 represent the arrangement of base 304. As in Fig. As shown in Figure 31, the second end 320 is integrated into the longitudinal element 324 of the base 304. In other words, the second end 320 and the longitudinal element 324 are a single piece (for example, a monolithic construction). In the illustrated construction, the second end 320 and the longitudinal element 324 are made of a non-magnetic material (for example, a polymer or a non-magnetic metal). Specifically, the second end 320 and the longitudinal element 324 are made of a die-cast aluminum alloy A383 (i.e., ADC12). The second end 320 includes a circular collar configured to surround a section of the main body 308.

[0035] As in Fig. As shown in Figure 31, the base 304 includes the recesses 208 to accommodate the cushions 212. The cushions 212 are designed to form the air gap G1. In the illustrated construction, the air gap G1 formed by the cushions 212 is approximately 0.2 millimeters.

[0036] Fig. Figure 32 represents the orientation of a pair of steel plates 332 surrounding a magnet 336 (i.e., the one in Fig. (See Figure 9, Sandwich Construction 220). The magnet 336 defines a sixth length L6, measured in a direction parallel to the longitudinal axis A1. The sixth length L6 is between approximately 18 millimeters and approximately 30 millimeters. In the construction shown, the sixth length L6 is approximately 23 millimeters. The magnet 336 defines a seventh length L7 (for example, a width), measured in a direction perpendicular to the longitudinal axis A1. The seventh length L7 is between approximately 1 millimeter and approximately 4 millimeters. In the construction shown, the seventh length L7 is approximately 3 millimeters. The magnet 336 defines an eighth length L8 (for example, a height), measured in a direction perpendicular to the longitudinal axis A1 and the direction of the seventh length L7. The eighth length L8 is between approximately 3 millimeters and approximately 6 millimeters. In the construction shown, the eighth length L8 is approximately 5 millimeters.In the illustrated construction, the volume of magnet 336 is approximately 345 mm. 3 .

[0037] Fig. Figure 33 shows the arrangement of the pair of steel plates 332 and the magnet 336 in a recess 340 of the longitudinal element 324. In the illustrated design, the longitudinal element 324 includes two recesses 340. In other designs, additional recesses may be added to the longitudinal element 324 to increase the number of steel plates 332 and magnets 336 in the longitudinal element 324. The base 304 includes a cover plate 344 and fastening elements 348 that extend through openings in the cover plate 344 to couple the cover plate 344 to the longitudinal element 324. The cover plate 344 is coupled to the longitudinal element 324 and covers the recess 340, so that the magnets 336 and the steel plates 332 are arranged between the longitudinal element 324 and the cover plate 344. In the illustrated construction, the cover plate 344 has approximately the same length in the direction of the longitudinal axis A1 as the longitudinal element 324.

[0038] With continued reference to Fig. 33, after the steel plates 332 and the magnets 336 have been inserted into their respective recesses 340, the cover plate 344 is attached to the longitudinal element 324 by means of the continuous fastening elements 348, so that the steel plates 332 and the magnets 336 are contained in the recesses 340. As shown in Fig. As shown in Figure 33, the steel plates 332 and the magnets 336 are arranged between the cover plate 344 and the longitudinal element 324. The longitudinal element 324 defines a surface 352 located on the side of the longitudinal element 324 opposite the cover plate 344. The longitudinal element 324 includes slots 356 on the surface 352, which are connected to the recesses 340, such that one end of the steel plates 332 projects into the slot 356. In the illustrated design, one end of the steel plates 332 is flush with the surface 352. In other designs, the steel plates 332 may be recessed relative to the surface 352 to increase the air gap G1. In other designs, the steel plates 332 may project relative to the surface 352 to decrease the air gap G1.

[0039] With further reference to Fig. 33 The longitudinal element 324 includes a projection 358 opposite the second end 320. In some designs, the projection 358 is configured to be received by a recess (not shown) of the first end 316 of the base 304. In other designs, the longitudinal element 324 includes a recess (not shown) configured to receive a projection 360 of the first end 316 (see Fig. 37). The projection 358 and the recess (not shown) of the longitudinal element 324 and the projection 360 of the first end 316 form an interface between the longitudinal element 324 and the first end 316, so that the first end 316 is rotationally fixed relative to the longitudinal element 324.

[0040] Fig. Figures 34 to 36 represent the arrangement of the main body 308. In Fig. Figure 34 shows how the main body 308 accommodates the PCB 236. The PCB 236 includes a wiring harness 364, which is routed through a section of the main body 308 located near the lamp head 312. The wiring harness 364 is configured to supply the lamp head 312 with energy from the power source 130 ( Fig. 45) to provide.

[0041] As in Fig. As shown in Figure 35, the main body 308 comprises mounting posts 368 arranged in an interior space of the main body 308. The main body 308 includes fastening elements 370 that pass through the mounting posts 368. The main body 308 comprises one end 372 with a circular cross-section, which receives the second end 320.

[0042] In Fig. Figure 36 shows the attachment of the attachment 330 and the second end 320 to the main body 308. The attachment 330 includes a circular projection 374 that extends from the attachment 330 in a direction parallel to the longitudinal axis A1. The attachment 330 includes mounting posts 376 that are aligned with the mounting posts 368 of the main body 308. The mounting posts 376 are arranged radially inward relative to the circular projection 374. The attachment 330 includes a mounting projection 378 that extends from the attachment 330 in a direction parallel to the longitudinal axis A1.

[0043] With continued reference to Fig. In section 36, the circular projection 374 of the second end 320 is positioned above the end 372 of the main body 308. The end 372 of the main body 308 defines a diameter that is smaller than the inner diameter of the second end 320, so that the second end 320 slides over the end 372 along the longitudinal axis A1. In the illustrated construction, the second end 320 is concentric with the end 372 of the main body 308.

[0044] If you turn briefly Fig. Figure 45 shows the connection between the attachment 330 and the main body 308. The end 372 includes a recess 380 that extends parallel to the longitudinal axis A1 into the end 372. The main body 308 includes a seal 382 arranged in the recess 380. The recess 380 receives the circular projection 374 of the attachment 330, so that the attachment 330 is arranged concentrically with the end 372. The connection between the attachment 330 and the main body 308 is also sealed by the seal 382. The mounting projection 378 holds the PCB 236 such that the PCB 236 is arranged between the attachment 330 and the power source 130. As shown in Fig. As shown in Figure 45, the battery 130, the battery holder 131, the end cap 134, the first end 316 and the second end 320 are all aligned relative to the longitudinal axis A1.

[0045] Out of Fig. Figure 36 shows that the attachment 330 is aligned with the end 372 of the main body 308 and that the fastening elements 370 extend through the mounting posts 368 of the main body 308 and into the mounting posts 376 of the attachment 330 to couple the attachment 330 to the main body 308. The second end 320 of the base 304 is clamped between the attachment 330 and the main body 308. The attachment 330 is mounted relative to the main body 308 and therefore acts as a contact point for a user, which can be grasped when rotating the base 304 relative to the main body 308 or when rotating the lamp head 312 relative to the main body 308.

[0046] Fig. 37 and Fig. Figure 38 represents the carabiner 328, which extends from the first end 316. The carabiner 328 defines a nose 384, a hook 386, and an opening 388. The carabiner 328 includes a clasp 390, which is pivotally coupled to the carabiner 328, and a spring 392, which biases the clasp 390 into engagement with the nose 384. In the illustrated construction, a section of the clasp 390 and the nose 384 define a stand 394 of the carabiner 328. As shown in Fig. As shown in Figure 37, the stand 394 is the surface of the closure 390 and the nose 384, which engages with the workpiece 216. The stand 394 is parallel to the surface 352 of the base 304.

[0047] As in Fig. As shown in Figure 38, the closure 390 includes a recess 396 that receives a section of the spring 392, so that the spring 392 biases the closure 390 towards closing the nose 384. The base 304 includes a fastening element 398 (for example, a shoulder screw) for coupling the first end 316 (for example, the carabiner hook 328) to the base 304. The fastening element 398 includes a threaded section 399A and an unthreaded section 399B. Although the projection 360 of the first end 316 engages in the recess (not shown) of the longitudinal element 324, so that the first end 316 is fixed against rotation relative to the longitudinal element 324, the fastening element 398 couples the first end 316 axially to the longitudinal element 324 relative to the longitudinal axis A1. In particular, the threaded section 399A of the fastening element 398 is screwed to the longitudinal element 324.Furthermore, the fastening element 398 couples the clasp 390 to the carabiner 328, allowing the clasp 390 to pivot relative to the carabiner 328. Specifically, the carabiner 328 is rotatable about the unthreaded section 399B of the fastening element 398. Additionally, the fastening element 398 is guided through an opening 400 in the spring 392. In other words, the fastening element 398 acts as the spring centering diameter. The single shoulder screw 398, used to couple the clasp 390 to the carabiner 328 and the carabiner 328 and the clasp 390 to the longitudinal element, reduces the number of parts required for assembly and results in a simplified design of the base 304.

[0048] Fig. Figure 39 represents the lamp head 312 of the portable lamp 300. The lamp head 312 comprises a housing 404 and a hinge 408, which is configured to allow the lamp head 312 to pivot about the lamp axis A2. The hinge 408 comprises a first plate 410, a plurality of fastening elements 412, a plurality of seals 414, and a second plate 416. The first plate 410 is made of a metal (for example, zinc, aluminum, steel). In the illustrated design, the first plate 410 is made of steel. The second plate 416 comprises a projection 418 with ribs 420 and a plurality of openings 422. In the illustrated design, the second plate 416 is made of a metal (for example, zinc, aluminum, steel). In the illustrated design, the second plate 416 is made of Zamak 5.

[0049] The first plate 410 includes a central opening 424 dimensioned to accommodate the ribs 420, and a plurality of openings 426 configured to accommodate the plurality of fasteners 412. The housing 404 includes a receptacle 430 configured to accommodate the projection 418 and the ribs 420. To assemble the hinge 408, the first plate 410 is attached to the housing 404, with the plurality of fasteners 412 extending through the plurality of openings 426 and into the housing 404. Seals of the plurality of seals 414 are arranged between adjacent ribs 420, and the projection 418 is inserted through the central opening 424 so that the projection 418 is received by the receptacle 430 of the housing 404. The multitude of seals 414 is designed to prevent water from entering through the hinge 408.The projection 418 includes a central opening 428, which allows the passage of the wiring harness 364.

[0050] Fig. Figure 40 represents a further construction of a second plate 432, which is interchangeable with the second plate 416. The second plate 432 includes a projection 434 extending from the second plate 432 in a direction opposite to that of the projection 418. The projection 434 includes a groove 436 configured to receive a seal 438, thus sealing an interface between the second plate 432 and the main body 308. Fig. Figure 45 shows the second plate 432 with the hinge 408, wherein the plurality of seals 414 is arranged to create a seal between the projection 418 and the receptacle 430 of the housing 404.

[0051] Fig. Figure 41 represents a lens assembly 439 of the portable lamp 300. The lens assembly 439 comprises a frame 440, a lens cover 442, a spacer 444, and the light source 136. In the illustrated design, the frame 440 is made of a polymer. In the illustrated design, the frame 440 is made of TPE 350BK001. In the illustrated design, the lens cover 442 is made of a polymer. In the illustrated design, the lens cover 442 is made of PC 1000R.

[0052] To assemble the lens assembly 439, the lens cover 442 is inserted into the frame 440, and the spacer 444 is inserted into the frame 440 such that it is positioned between the lens cover 442 and the light source 136. The light source 136 is attached to the post 448 of the lens cover 442. The PCB 252 is connected to the light source 136.

[0053] As in Fig. As shown in Figure 42, the cable harness 364 is routed through the hinge 408 and connected to the PCB 252. The PCB 252 is then coupled to the housing 404 of the lamp head 312 via fastening elements 452. Fig. Figure 43 shows how the lens assembly 439 is coupled to the housing 404. The frame 440 includes posts 454, which are designed to receive fasteners 456. To couple the frame 440 to the housing 404, the fasteners 456 are guided through the housing 404 and into the posts 454. Fig. Figure 44 illustrates how the luminaire head 312 is coupled to the main body 308. To couple the luminaire head 312 to the main body 308, fastening elements are inserted through the multiple openings 422 of the second plate 416 and into the main body 308.

[0054] Fig. Figure 45 shows a cross-section through the longitudinal axis A1 of the fully assembled portable lamp 300. The portable lamp 300 comprises the end cap 134, which is coupled to the main body 308 near the first end 316 of the base 304. In particular, the end cap 134 is screwed to the main body 308 such that the first end 316 is clamped between the end cap 134 and the main body 308. The first end 316 includes a seal 460, which is arranged between the first end 316 and the main body 308, and the end cap 134 includes a seal 462, which is arranged between the end cap 134 and the main body 308. The seal 460 is configured to create resistance between the main body 308 and the carabiner 328.The resistance between the main body 308 and the carabiner 328 is designed such that the position of the main body 308 relative to the base 304 (for example, the carabiner 328) does not change unless a user rotates either component relative to the longitudinal axis. In the illustrated design, the resistance (i.e., the torque) for movement of the main body 308 relative to the base 304 is between 1.7 in-lb and 7.5 in-lb. The torque was measured by holding the carabiner 328 and biasing an edge of the lamp head 312 along axis A2 at the point furthest from the main body 308. The seal 462 is designed to prevent the ingress of water between the main body 308 and the end cap 134. Fig. Figure 45 shows that the end cap 134 includes a power contact 464A which makes a connection to the power source 130 so that power is supplied to the PCB 252.

[0055] Fig. Figure 46 represents the electrical contact 464A. The electrical contact 464A includes an elastomeric buffer 468 (for example, rubber, neoprene, etc.). The elastomeric buffer 468 is designed to deform when the end cap 134 is coupled to the main body 308. The electrical contact 464A includes a central terminal 470, which is in contact with a central section of one end of the power source 130. A spring (not shown) is arranged between the central terminal 470 and the elastomeric buffer 468, such that the central terminal 470 is biased toward a retaining cover 472. The electrical contact 464A includes peripheral terminals 474A, which are biased toward the retaining cover 472 by springs 476. Fig. Figure 47 represents another embodiment of a current contact 464B, which is interchangeable with the current contact 464A. Unlike the current contact 464A, the current contact 464B includes peripheral terminals 474B, which are leaf springs. Further details of the current contacts 464A, 464B, and the battery 130 and / or their functions are disclosed in U.S. Patent Application No. 19 / 382,461, the entire contents of which are incorporated herein by reference.
