[0007] Before the details of the disclosure are explained, it should be noted that the application of the disclosure is not limited to the details of the execution and the arrangement of the components set out in the following description or illustrated in the following drawings. The disclosure is also practical or feasible in other embodiments and in various ways. Detailed description

[0008] Fig. Figure 1 shows a portable power supply 100 with a housing 104 and a frame 108 surrounding the housing 104. The housing 104 includes one or more cable winding hooks 110. The housing 104 includes one or more wheels 112. In some versions, the wheels are coupled to the frame 108. The housing 104 includes a storage compartment 114. The storage compartment 114 includes a cover 115, which is closed but can be opened to expose the storage compartment 114. Fig. 22). The frame 108 includes one or more feet 116 in addition to the wheels 112. The wheels 112 and the feet 116 are designed to engage with a support surface 118.

[0009] The portable power supply 100 comprises a power input unit 120 and a power outlet 124. The power input unit 120 includes electrical connection interfaces, such as a cable or power cord 125, configured to receive power from an external power source, such as mains power from a wall outlet 126. In some configurations, the external power source is a direct current (DC) source. The DC source could be, for example, one or more photovoltaic cells (such as a solar panel), an electric vehicle (EV) charging station, or another DC source. In some configurations, the external power source is an alternating current (AC) source. The AC source could be, for example, a conventional wall outlet, such as a 120 V outlet or a 240 V outlet, as found in North America.As another example, the AC power source can be a conventional wall outlet, such as a 220 V outlet or a 230 V outlet as found outside North America. In some embodiments, the power supply unit 120 also includes one or more devices, such as antennas or induction coils, configured to receive power wirelessly from an external power source. The power received by the power supply unit 120 can be used to charge a core battery or a power source 128, which is at least partially located within the housing 104.

[0010] The current received from the power input unit 120 can also be used to supply one or more devices connected to the socket 124. The socket 124 comprises one or more sockets. In the illustrated embodiment, the socket 124 comprises a plurality of AC sockets 124A and DC sockets 124B. It is understood that the number of sockets contained in the socket 124 does not refer to the number shown in Fig. The number of sockets shown is limited. For example, socket 124 in some versions of power supply 100 may contain more or fewer sockets than the sockets shown in the illustrated version of power supply 100. In some versions, the socket includes two 20 A double sockets and one 30 A socket.

[0011] In some versions, socket 124 is configured to supply power from power source 128 to one or more peripheral devices. In some versions, socket 124 is configured to supply power from an external power source directly to one or more peripheral devices. These peripheral devices may include a smartphone, tablet computer, laptop computer, portable music player, power tool, power tool battery, power tool battery charger, or similar devices. The peripheral devices are configured to receive direct current and / or alternating current from socket 124.

[0012] The portable power supply 100 includes a bracket 132. Fig. Figure 1 shows the bracket 132, which is coupled to the frame 108 in a retracted position. In other embodiments, the bracket 132 is coupled to the housing 104. In other words, the bracket 132 is compatible with the housing 104. For the sake of simplicity, however, only the interface between the frame 108 and the bracket 132 will be explained. The bracket 132 includes an actuating element 136, which is received by a grip 140 of the handle 132.

[0013] Fig. Figure 2 shows the bracket 132 with one or more tubes 144, which are coupled at one end 148 to the handle 140. The housing 104 includes a recess 150, which is configured to hold the bracket 132 in the retracted position ( Fig. 1) accommodates. In the illustrated embodiment, the bracket 132 is a telescopic bracket. The tubes 144 are accommodated by the frame 108 and are displaceable relative to the frame 108. Fig. Figure 2 shows the bracket 132 in an extended position. From the retracted position ( Fig. 1) In the extended position, the bracket 132 is axially movable along a longitudinal axis A1, which is defined by the section of the frame 108 that receives the bracket 132. In particular, the handle 140, in the extended position, is arranged at an axial position on the longitudinal axis A1 at a point furthest from the frame 108.

[0014] Fig. Figure 3 shows an exploded view of the handle 132. The handle 140 consists of a main body 152 and a cover 156. In the illustrated embodiment, the main body 152 extends between the tubes 144. The main body 152 comprises one or more hollow ends 160, which have a shape matching the ends 148 of the tubes 144. In particular, the ends 160 of the main body 152 are nominally smaller than the ends 148 of the tubes 144, so that the body 152 is received within the tubes 144 (for example, the ends 160 are received within the ends 148). In other embodiments, the tubes 144 are received within the body 152 (for example, the ends 148 are received within the ends 160). In the illustrated embodiment, the body 152 includes a recess 166 which extends into the body 152 in a direction parallel to the axis A1 and between the tubes 144.The recess 166 extends over a large part of the length of the handle 140, measured along a handle axis A2 that runs transversely (e.g., perpendicularly) to the axis A1. The recess 166 axially overlaps at least one of the ends 160 along the longitudinal axis A1, so that a passage extends between the tubes 144 and the handle 140. The recess 166 is designed to receive the actuating element 136.

[0015] The actuating element 136 comprises a main body 170 and a projection 174. In the illustrated embodiment, the main body 170 extends over a large portion of the length of the recess 166, such that a section of the main body 170 axially overlaps one of the ends 160 along the longitudinal axis A1. In some embodiments, the main body 170 extends along the entire length of the handle 140 along the handle axis A2. The projection 174 extends outward from the main body 170 in a direction parallel to the longitudinal axis A1. In the illustrated embodiment, the projection 174 is located centrally on the main body 170. In other words, the projection 174 is situated on the main body 170 midway between the ends 160. The actuating element 136 is designed to move when actuated by a user.In the illustrated embodiment, the actuating element 136 is displaceable along an actuating element axis A3, which runs parallel to the longitudinal axis A1.

[0016] The cover 156 encloses the recess 166 containing the actuating element 136. The cover 156 comprises a main body 178 and an opening 182. The main body 178 extends over most of the length of the handle 140, measured along a handle axis A2 that runs transversely (for example, perpendicularly) to the axis A1. In some embodiments, the main body 178 completely covers the recess 166. The projection 174 of the actuating element 136 is received in the opening 182 of the cover 156 and extends through the opening 182. The projection 174 is positioned so that a user can actuate the actuating element 136 through the opening 182.

[0017] The bracket 132 comprises one or more elongated rigid elements 186 and a locking assembly 190. The rigid elements 186 are movably mounted in the tubes 144 and the main body 152. In particular, one end 192 of the rigid element 186 is coupled to the main body 170 of the actuating element 136 via the passage between the tubes 144 and the body 152 (for example, the tubes 144 and the body 152 are hollow at ends 148 and 160, respectively). Thus, when the actuating element 136 is actuated, the rigid elements 186 are movable along the longitudinal axis A1 along the actuating element axis A3. At least one of the rigid elements 186 is coupled to the locking assembly 190 at a different end 196 opposite the end 192. The locking assembly 190 comprises a locking housing 200, a wedge element 204 and a pin element 208.

[0018] Fig. Figure 4 shows the locking housing 200 with a main body 212, which includes a first locking housing end 216 with an opening 218 to slidably receive the wedge element 204 ( Fig. 4) The main body 212 includes a collar 220 at a second locking housing end 224 opposite the first locking housing end 216. The collar 220 has a greater width and height compared to the main body 212. The main body 212 includes an opening 228 defined in the locking housing between the first and second locking housing ends 216, 224. The main body 212 slidably receives the pin element 208 in the opening 228. The main body 212 has a shape corresponding to the tubes 144 from the first locking housing end 216 to the collar 220, such that the locking housing 200 is received in one end 232 of the tubes 144. The end 232 is opposite the end 148. Apart from the collar 220, the main body 212 is nominally smaller than the tubes 144, so that the locking housing 200 is accommodated in the tubes 144.The collar 220 prevents the main body 212 from being inserted too deeply along the longitudinal axis A1 due to its greater width and height compared to the interior of the tubes 144. In other words, the collar 220 positions the main body 212 axially along the longitudinal axis A1. In the illustrated embodiment, at least one of the tubes 144 includes a defined opening 236 located near the end 232. After the locking housing 200 is fully inserted into the tubes 144, the opening 228 of the main body 212 and the opening 236 of the tubes 144 overlap axially along the longitudinal axis A1.

[0019] Fig. Figure 4 shows the wedge element 204, which comprises a main body 238 with a wedge end 240 and another wedge end 244 opposite the wedge end 240, the other wedge end 244 comprising an inclined wall 248. The elongated rigid element 186 is coupled to the wedge element 204 and extends away from the wedge end 240. The pin element 208 comprises a main body 250 with a pin end 252, which includes a corresponding inclined wall 256 that engages with the inclined wall 248. In other words, the pin end 252 is complementary to the other wedge end 244, so that the inclined walls 248 and 256 engage with each other. The locking assembly 190 includes a preloading device 260 (for example, a spring) to press the pin element 208 along a locking axis A4. The preloading device 260 is arranged between the locking housing 200 and the pin element 208.In the illustrated embodiment, the locking axis A4 runs transversely (for example, perpendicularly) to the longitudinal axis A1 and parallel to the handle axis A2. The pin element 208 comprises a pin 264 that extends from the main body 250 in one direction along the locking axis A4. The pin 264 is arranged on a wall opposite the point where the preloading device 260 engages the main body 250.

[0020] The wedge element 204 is movable along the longitudinal axis A1 when the actuating element 136 is actuated or when the pin element 208 engages due to the preloading device 260. The pin element 208 is movable along the locking axis A4 when the wedge element 204 engages or when the preloading device 260 moves. The wedge element 204 is limited to axial movement along the longitudinal axis A1, and the pin element 208 is limited to axial movement along the locking axis A4, which runs transversely (e.g., perpendicularly) to the longitudinal axis A1.

[0021] Fig. Figure 5 shows the bracket 132, which is received in the frame 108, with the housing 104 concealed. The frame 108 includes one or more openings 270 defined therein. The openings 270 are axially spaced along the longitudinal axis so that the bracket 132 is adjustable along the longitudinal axis A1.

[0022] Fig. 4 and Fig. Figure 5 shows the locking assembly 190 in a locked position. In the locked position, the preloading device 260 presses the pin element 208 along the locking axis A4, so that the pin 264 protrudes from the locking housing 200 and the tubes 144 and comes into contact with the frame 108. In other words, the pin 264 extends through the openings 228, 236, 270 of the main body 212, the tubes 144, and the frame 108, so that the pin 264 engages in the frame 108. Specifically, the pin 264 engages in the opening 270. In the locked position, the openings 228, 236, 270 overlap axially along the longitudinal axis A1. In the locked position, the end 240 of the wedge element 204 is located furthest from the collar 220 along the longitudinal axis A1.

[0023] Fig. 6 and Fig. Figure 7 shows the locking assembly 190 in an unlocked position. To unlock it from the locked position ( Fig. 4-5) To reach the unlocked position, the actuating element 136 is moved along the actuating element axis A3. The rigid element 186 is moved along the longitudinal axis A1, as the rigid element 186 is coupled to the actuating element 136 to move with it. The wedge element 204 is moved axially along the longitudinal axis A1, as the wedge element 204 is coupled to the rigid element 186 to move with it. When the wedge element 204 is moved axially along the longitudinal axis A1, the inclined wall 248 engages the corresponding inclined wall 256 of the pin element 208 (for example, the wedge element 204 is moved along the longitudinal axis A1 in the direction of the collar 220). This causes the pin element 208 to be displaced along the locking axis A4 against the preload force of the preloading device 260 in response to the axial displacement of the wedge element 204 in the direction of the collar 220.The pin 264 is retracted further into the locking housing 200 in response to the axial displacement of the pin element 208 along the locking axis A4. The unlocked position is a position in which the pin 264 is received into the locking housing 200 to such an extent that it does not engage with the frame 108 (for example, the pin 264 is recessed relative to the frame opening 270). For example, in the unlocked position, the pin 264 is flush with the body 212 of the locking housing 200.

[0024] Fig. Figure 8 shows another embodiment of a portable power supply 300. The portable power supply 300 is similar to the portable power supply 100; therefore, only the differences are explained. The portable power supply 300 comprises a frame 304 with one or more longitudinal tubes 308 fixed to the frame 304. In the embodiment shown, the tubes 308 extend from the frame 304 in a direction parallel to the longitudinal axis A1. In particular, the tubes 308 are fixed to a central section of the frame 304. The central section of the frame is located between one side of the power supply 300 with the wheels 112 and the feet 116 and a side opposite the side with the wheels 112 and feet 116. The portable power supply 300 includes a bracket 312, which is supported by the longitudinal tubes 308. In further embodiments, the bracket 312 is interchangeable with the bracket 132.In the illustrated embodiment, the bracket 312 comprises one or more tubes 316 and a handle 320, which is coupled to the tubes 316. In the illustrated embodiment, the bracket 312 is a telescopic bracket. The bracket 312 is displaceable along the longitudinal axis A1. The bracket 312 is movable between the retracted position and the extended position.

[0025] Fig. Figure 9 shows the bracket 312 in the extended position, such that the handle 320 is positioned on the longitudinal axis A1 furthest from the frame 304. The bracket 312 is prevented from moving too far along the longitudinal axis by adjusting screws that engage with the frame 304 or the tubes 308. Unlike the bracket 132, the bracket 312 provides additional length along the longitudinal axis A1 due to the longitudinal tubes 308. This additional length increases the leverage for transporting the portable power supply 300. Furthermore, the length prevents accidental contact by the user during transport (for example, if their heels bump against the portable power supply 300).

[0026] Fig. Figure 10 shows another embodiment of a portable power supply 400. This portable power supply is similar to the portable power supply 100, so only the differences are explained. The portable power supply 400 comprises a housing 404 and a frame 408 that surrounds the housing 404. The housing 404 includes one or more wheels 412. In some embodiments, the wheels are coupled to the frame 408. The frame 408 includes one or more feet 416 in addition to the wheels 412. The housing 404 comprises a bottom 420 near the wheels 412 and the feet 416, and a top 424 opposite the bottom 420. The top 424 partially defines a plane X1 ( Fig. 11).

[0027] The portable power supply 400 comprises a rod 428 that is pivotally coupled to the housing 404. The rod 428 is a pivoting lifting rod. In other words, the rod 428 is capable of supporting the weight of the portable power supply 400 when used as a lifting point to raise the power supply 400. In some embodiments, the rod 428 is rated for a load of 800 lb and a yield strength of 195 MPa. In the embodiment shown, the rod 428 is made of grade #45 steel. In the embodiment shown, the rod 428 weighs between 1 kg and 2 kg. More precisely, in the embodiment shown, the rod 428 weighs 1.15 kg. The rod 428 is coupled to the housing 404 near the top 424. In other embodiments, the rod 428 is coupled to the frame 408. The 428 pole is compatible with the 100 and 300 portable power supplies.

[0028] Fig. Figure 11 shows that the rod 428 comprises a pair of parallel segments 432 coupled to the housing 404. In the illustrated embodiment, the rod 428 is a solid rod. In some embodiments, the rod 428 is a hollow rod. In the illustrated embodiment, the rod 428 defines a diameter D1. In some embodiments, the diameter D1 is less than 20 millimeters. In the illustrated embodiment, the diameter D1 is 13 millimeters. The rod 428 comprises a pair of angled segments 436 coupled to the pair of parallel segments 432. Each of the angled segments 436 is offset from a corresponding segment of the pair of parallel segments 432 by a non-zero angle Ø1. In the illustrated embodiment, the angle Ø1 is less than 180 degrees. More precisely, the angle Ø1 is 112 degrees. The angled segments 436 meet in the middle of the rod 428 and are connected to each other at a vertex 440.The rod 428 comprises a horizontal segment 444 that runs transversely (for example, perpendicularly) to the pair of parallel segments 432. The horizontal segment 444 extends between the pair of angled segments 436. The rod 428 comprises a pair of segments 448 that extend between the horizontal segment 444 and the pair of angled segments 436. In the illustrated embodiment, the two segments 448 are parallel to each other and define a width W1. In the illustrated embodiment, the width W1 is at least 2 inches, so that a 2-inch fastening strap is accommodated between the segments 448. In the illustrated embodiment, the two segments 448 are parallel to the two parallel segments 432.

[0029] Fig. Figure 12 shows a segment of the pair of parallel segments 432 that are pivotably coupled to the housing 404, such that the rod 428 pivots about a pivot axis A5. In the illustrated embodiment, the rod 428 includes a flange 452 located near one end 456 of the rod 428. The housing 404 includes a recess 460 defined in the housing 404. In particular, the recess 460 extends from the top 424 to the bottom 420. The pivot axis A5 extends through the recess 460. The rod is located between a stationary position ( Fig. 10-12) and a stowage position ( Fig. 13) movable.

[0030] Fig. Figures 10-12 show the rod 428 in its upright position. The rod 428 extends from the underside 420 and intersects the plane X1 in the upright position. The end 456 of the rod 428 is designed to engage in the recess 460 of the housing 404 in the upright position. In the upright position, the rod 428 maintains its position without external forces (e.g., preload forces, press fits, etc.). Thus, the pivoting movement between the upright position and the stowed position occurs without the rigid movement that would be caused by preload forces or press fits.

[0031] Fig. Figure 13 shows the rod 428 in the stowed position. The housing 404 includes projections 468 that engage the rod 428. In the illustrated embodiment, the projections 468 extend into the recess 460, so that the rod 428 is received in the recess 460.
