[0062] Before explaining any embodiment of this utility model in detail, it should be understood that the application of this utility model is not limited to the details of the construction and arrangement of the components set forth in the following description or shown in the following drawings. This utility model can have other embodiments and can be practiced or implemented in various ways.

[0063] Furthermore, it should be understood that the wording and terminology used in this invention are for descriptive purposes and should not be considered restrictive. The modifier “about” used in conjunction with a quantity includes the stated value and has a meaning determined by the context (e.g., it at least includes the degree of error associated with the measurement of the particular quantity). The modifier “about” should also be considered as disclosing a range defined by the absolute values ​​of its two endpoints. For example, the statement “about 2 to about 4” also discloses a range of “2 to 4”. The term “about” can refer to a number plus or minus 10%. For example, “about 10%” can represent a range of 9% to 11%, and “about 1%” can mean 0.9 to 1.1. Other meanings of “about” are obvious from the context, such as rounding; therefore, for example, “about 1” can also represent 0.5 to 1.4.

[0064] Figure 1 A standing lamp 50 is shown. The standing lamp 50 is portable and includes a base 65 and a lamp head 55. The lamp head 55 can be connected via... Figure 4 The extension rod 105 shown extends away from the base 65. The extension rod 105 and related hardware disclosed in this utility model ensure that the extension rod 105 remains extended when partially raised (i.e., does not retract from the extended position back to the retracted position, as...). Figure 6 The improved capabilities (shown in the best embodiment) are also present. The floor lamp 50 disclosed in this invention also provides downward-oriented or upward-oriented light at its maximum extension (i.e., when the extension rod 105 is fully extended). When the extension rod 105 is fully extended, the lamp head 55 can be positioned, for example, up to 7 feet above the ground. The floor lamp 50 disclosed in this invention also has the ability to provide ambient lighting to a room. This is achieved through a “super high” mode with relatively high light output intensity, allowing the floor lamp 50 to provide ambient lighting to the entire work area (i.e., the entire room). Additionally, the “super high” mode can provide relatively bright lighting for a single task, i.e., when light is to be directed to a relatively small work area.

[0065] Figure 1 and Figure 2 The standing lamp 50 is shown in its folded position, and Figure 4 A standing lamp 50 in an extended position is shown. The standing lamp 50 includes a light-emitting lamp head 55, a body 60, and a base 65. The body 60 connects the base 65 to the lamp head 55.

[0066] The main body 60 includes an upper component 82, which includes a user interface (UI) panel 70. The UI panel 70 includes buttons, lights, etc., which a user can use to control various features of the standing lamp 50. The upper component 82 also includes an auxiliary handle 80 and a protrusion 102. The auxiliary handle 80 can be gripped by the user to carry the standing lamp 50. The protrusion 102 extends outward from the rest of the upper component 82 and then downward (i.e., away from the longitudinal axis 110, and then downward along the longitudinal axis 110 toward the base 65). When the standing lamp 50 is mounted to or placed on other structures such as a trolley (see...), Figure 8 When in use, protrusion 102 is adapted to hold the vertical lamp 50. For example... Figure 3A As best shown, the upper assembly 82 also includes a channel 72, which is formed relative to the longitudinal axis 110 by two protrusions 73 defining the opposite lower portion 74. When the lamp head 55 is retracted, or in other words, when the extension rod 105 is fully retracted and nested with each other and within the body 60, the channel 72 is shaped to receive the lamp head 55.

[0067] like Figure 1 and Figure 2 As shown, the main body 60 also includes a main handle 75 and a protective housing 107. The main handle 75 is disposed perpendicular to the secondary handle 80. The main handle 75 extends along and is spaced apart from the protective housing 107, and includes a slidable portion 86. The slidable portion 86 is slidable along the main handle 75 in a direction along the longitudinal axis 110. An actuator 87 is disposed on the slidable portion 86, and when actuated, the slidable portion 86 is unlocked and thus slidable along the main handle 75. In other examples, instead of the actuator 87, a trigger 85 is located on the main handle 75 for unlocking the slidable portion 86 to allow movement along the main handle 75. For illustrative purposes, both are... Figure 1 and Figure 2 As shown, only one of the trigger 85 and actuator 87 is needed. The longitudinal axis 110 extends from a first end 142 of housing 107 to a second end 144 of housing 107. An extension rod 105 is housed within and coaxial with housing 107, which is typically in the form of an elongated body. In some examples, the main handle 75 may extend along the longitudinal axis 110 beyond half the length of the floor lamp 50. Figure 1 and Figure 2 ), and in other examples, the length extending along the longitudinal axis is less than that of the vertical lamp 50 ( Figure 4When the trigger 85 is pressed or the actuator 87 is actuated, the lamp stand 50 is released from the folded position, and the legs 100 unfold from their position against the protective housing 107 to support the rest of the lamp stand 50. Although the present invention shows a lamp stand 50 with three legs 100, lamp stand 50s with more or fewer legs 100 are conceivable. As the legs move along the longitudinal axis 110 and unfold away from the housing 107, the slidable portion 86 can slide along the main handle 75 together with the legs 100. Figure 4 and Figure 6 This best illustrates the point. Return to reference. Figure 1 and Figure 2 The extension rod 105 is housed within the protective housing 107 and extends from the protective housing 107 along the longitudinal axis 110. The longitudinal axis 110 extends along the centerline of the generally cylindrical protective housing 107. The extension rod 105 is nested within the protective housing 107 and is retractable, and is telescopically extendable to support the lamp head 55 at different distances above the upper assembly 82. In other words, the extension rod 105 supports the lamp head 55 when it is located within the channel 72, when it is at its maximum extended position above the upper assembly 82, and at any point therein along the longitudinal axis 110.

[0068] like Figure 3A As shown, when the extension rod 105 is received within the housing 107, the lamp head 55 is located within the lower portion 74, such that the lamp head 55 is substantially flush with the protrusion 73 of the upper assembly 82. In some configurations, when the lamp head 55 is located within the lower portion 74, the lamp head 55 may be recessed relative to the protrusion 73 of the upper assembly 82. The lamp head 55 is generally hexagonal in shape. A lamp head connector 115 is connected to the lamp head 55 within the generally hexagonal perimeter 118 of the lamp head 55, such that the first lobe 116 and the second lobe 117 extend to opposite sides of the lamp head connector 115. The space 119 between the first lobe 116 and the second lobe 117 provides clearance for the lamp head connector 115 and causes an interruption in the generally hexagonal perimeter 118 of the lamp head 55 shape. A handle 114 is provided opposite the space 119 on the lamp head 55. The handle 114 provides the user with a position to grip the lamp head 55 for tilting and adjusting it relative to the lamp head connector 115. The handle 114 also provides the user with a position to pull the lamp head 55 away from the rest of the lamp stand 50, thereby extending the extension rod 105 out of the housing 107. By integrating the handle 114 and the space 119 as integral features of the lamp head 55, all lying in a single plane, a relatively thinner lamp head 55 can be provided. Furthermore, by recessing the lamp head 55 into the lower portion 74 (which is possible thanks to the relatively thin design of the lamp head 55), the protrusion 73 and the auxiliary handle 80 serve to protect the lamp head 55 during transport of the lamp stand 50.

[0069] The lamp holder 55 also includes a panel 113, which may be opaque or translucent. For illustrative purposes, Figure 3A The panel 113 shown is half opaque and half translucent. As can be seen through the translucent portion, light-emitting diodes (LEDs) 112 are mounted in rows and columns behind the panel 113 and on an LED plate 111. Although as... Figure 3A As shown, LED 112 and LED board 111 are oriented to project light upwards, but in other embodiments, additional LED 112 and another LED board 111 may be mounted at the bottom (e.g., Figure 3A (as shown) to project light downwards (e.g., in the direction ... Figure 3A The light-emitting diodes 112 in the lamp 50 project light in opposite directions. Better light coverage of the work area can be achieved by installing light-emitting diodes 112 facing more than one direction. Other arrangements of the light-emitting diodes 112 can be envisioned based on the lighting requirements of the lamp 50. In some examples, the light-emitting diodes 112 are not arranged in rows or columns, but are spaced approximately equidistantly on the light-emitting diode panel 111. In other examples, the light-emitting diodes 112 may be tilted to project light in a non-uniform direction relative to each other. Regardless of the orientation of the light-emitting diodes 112, in operation, the light-emitting diodes 112 illuminate the work area through the panel 113 (whether opaque or translucent).

[0070] Return to reference Figure 1 and Figure 2 The base 65 can be connected to a battery 90 (e.g., a battery pack) for powering the floor lamp 50. The battery 90 can be removable and rechargeable. For example, the battery 90 can be a power tool battery pack. In some embodiments, the battery 90 can be an 18-volt lithium-ion battery pack. In other embodiments, the battery 90 can have other voltages and / or chemical properties. The base 65 also includes a power port 95 for powering the floor lamp 50 via an external power source, charging the battery 90 via an external power source, and / or (e.g., via an extension cord) powering other devices.

[0071] Figure 3B A perspective view of the upper component of the vertical lamp 50 with the lamp head 55 removed is shown, with the overall view being approximately the same as that of the bracket lamp 50 shown in Figure 3A. Figure 3B The protrusion 73 and lower portion 74 of the upper assembly 82 are shown more clearly. When in the fully retracted position, the protrusion 73 and lower portion 74 together form a channel 72 for receiving the lamp head 55.

[0072] Figure 3BWiring 130 passing through lamp holder connector 115 is also shown, with wiring 130 connecting to lamp holder 55. Wiring 130 provides power and electrical control to lamp holder 55. On the opposite side of wiring 130 passing through lamp holder connector 115, connection hardware 132 is provided for physically connecting lamp holder connector 115 to lamp holder 55. As shown, connection hardware 132 may include bracket 132A and at least one fastener 132B. Bracket 132A is connected to lamp holder 55 and is rotatable about fastener 132B to allow lamp holder 55 to rotate about fastener 132B. In the embodiment shown in this invention, wiring 130 passes through first lobe 116, and connection hardware is connected to second lobe 117. This provides maximum clearance for lamp holder 55 to rotate about lamp holder connector 115 and limits kinking and bending of wiring 130 caused by movement of lamp holder 55 relative to lamp holder connector 115. The position of wiring 130 also contributes to the relatively thin design of lamp holder 55. In other examples, a molded rotatable connector can be used to secure the lamp holder 55 to the lamp holder connector 115.

[0073] Figure 4 The diagram shows the situation where the main handle 75 moves so that the outrigger 100 is in the extended position. Figure 4 The main handle 75 shown also includes a trigger 85 to release the leg 100 before it moves from the folded position to the unfolded position. In some examples, the leg 100 is locked in the unfolded position, and the trigger 85 (or actuator 87) is also pressed to release the leg 100 from the unfolded position to move it back to the folded position.

[0074] Figure 5A and 5B A lamp holder connector 115 is shown, which connects the lamp holder 55 to the uppermost extension rod 105. The lamp holder connector 115 connects the lamp holder 55 to the extension rod 105 such that the lamp holder 55 can rotate 360 ​​degrees about the longitudinal axis 110 relative to the uppermost extension rod 105, and can rotate 180 degrees on the lamp holder connector 115 (i.e., rotate 90 degrees forward or backward from the longitudinal axis 110).

[0075] Figure 6 The relative dimensions of the standing lamp 50 in the fully folded position 50A, the partially extended position 50B with the support leg 100 extended and supporting the standing lamp 50, and the fully extended position 50C with the support leg 100 extended and the extension rod 105 fully extended are shown. In positions 50B and 50C, the support leg 100 holds the base 65 above the bottommost extension of the support leg 100, such that the base 65 is above the ground in positions 50B and 50C.

[0076] Figure 6It is also shown how each leg 100 includes a first end 103 hinged to the housing 107 and a second end 104 opposite to the first end 103. The second end 104 of each leg 100 is movable between a folded position abutting against the housing 107 (e.g., at position 50A) and an unfolded position in which the second end 104 of each leg 100 is separated from the housing 107 (e.g., at positions 50B and 50C). In an embodiment including a sliding portion 86 (see...) Figure 1 and Figure 2 When the support leg 100 moves from the folded position to the unfolded position, the sliding portion 86 moves together with the first end 103 along the longitudinal axis 110.

[0077] Figure 6 The compact design of the floor lamp 50 compared to other products is also specifically shown at location 50A. The lamp head 55 is folded along the longitudinal axis 110 via the lamp head connector 115 (i.e., hinge) to achieve a relatively thin profile. The body 60 includes an extension rod 105, which in some embodiments does not include a locking cam because this function is replaced by a friction-fit connection, which will be referenced... Figure 17-22 To explain in more detail: The base 65 is relatively compact, and the extension rod 105 is telescopic, which minimizes the overall length of the vertical lamp 50 when the extension rod 105 is retracted into the protective housing 107.

[0078] Figure 7A A detailed view of the base 65 of the standing lamp 50 is shown, with particular attention to the second end 104 of each leg 100. Each of the legs 100 includes a main portion 230 that represents the majority of the total length of the leg 100 and extends generally parallel to the longitudinal axis 110 in the folded position. Near the second end of the leg 100, an offset portion 235 is provided, extending orthogonally from the main portion 230 and connecting the main portion 230 to the foot 240. When the leg 100 is in the unfolded position, the foot 240 contacts the ground. When the leg 100 is in the folded position, the base 65 contacts the ground and the leg 100 hangs above the ground. The main portion 230, the offset portion 235, and the foot 240 together follow the contour 245 of the base 65 (indicated by dashed lines). By making the legs 100 follow the contour 245, the standing lamp 50 in the folded position is tightly wrapped around the base 65, thus making it easier for the user to transport. The feet 240 of the support leg 100 in the folded position are spaced apart around the base 65, allowing the user to access the battery 90 (e.g., allowing the user to replace the battery 90 when the lamp 50 is in the folded position) and the power port 95 (e.g., allowing the user to access the power port 95 when the lamp 50 is in the folded position), which is shown in this invention behind the cover 96.

[0079] Figure 7B The relative positions of the main internal components of the floor lamp 50 are shown. The lamp holder 55 includes a light-emitting diode (LED) assembly 145 (including, for example, individual LEDs 112 and an LED board 111), which is connected to components in the base 65 via wiring 130. Wiring 130 extends through an extension rod 105. In other embodiments, wiring 130 may be located outside the extension rod 105. The base 65 includes a printed circuit board (PCB) 140, a battery terminal 135 (for receiving a battery 90), and an AC port component 150 (e.g., a power port 95). The battery terminal 135 is schematically shown with a dashed box because... Figure 7B The cross-sectional view obscures most of the structure of battery terminal 135.

[0080] Figure 7C A view of the base 65 of the vertical lamp 50 is shown, in which the support leg 100 is removed to better show the support leg link 137 (in Figure 6 (Also visible in the image). The outrigger link 137 connects the base 65 to the outrigger 100, and can be accessed from... Figure 7C The position shown, roughly extending along the longitudinal axis 110, is rotated to Figure 6 The leg link 137 shown extends perpendicularly to the longitudinal axis 110. The leg link 137 limits the extension of the second end 104 of the leg 100 away from the housing 107, allowing the pedestal lamp 50 to be positioned above the ground together with the base 65, as shown in Figures 50B and 50C in Figure 6. For connection to the base 65, the leg link 137 passes through a slot 139 in the cover 138 of the base 65. The slot 139 is elongated and provides clearance for the leg link 137 as it rotates with the leg 100 between an extended and retracted position. In some examples, the leg link 137 is formed in a U-shape from a single piece of material (e.g., steel), with the bottom of the U-shape connected to the base 65.

[0081] In some embodiments, the floor lamp 50 may be integrated as part of a PACKOUT storage system sold by Milwaukee Tool. For example, Figure 8 This illustrates how the protrusion 102 of the upper component 82 is configured to hook onto the trolley 125, allowing the trolley 125 to be used to transport the standing lamp 50 to or from the work site. Figure 1 As shown in Figure 3, the protrusion 102 is located on the opposite side of the upper assembly 82 relative to the auxiliary handle 80. The weight of the upright lamp 50 holds the protrusion 102 engaged with the trolley 125, and therefore, in such an embodiment, additional connecting structures may not be required.

[0082] Figure 9A and 9BA fork-shaped member 155 is shown that can be connected to one of the legs 100 of the vertical lamp 50. Figure 11 In the diagram, the fork-shaped member 155 is shown without any obstructing structure. The fork-shaped member 155 can be connected to the support structure 120, such as the PACKOUT box of a PACKOUT storage system sold by Miwage Tools, so that the upright lamp 50 can be transported to the work site using the support structure 120. See comparison... Figure 9A and Figure 10 As shown, the fork-shaped member 155 rotates out of its nested position within the cavity 162 of the support leg 100. When the fork-shaped member 155 is nested within the cavity 162, it is generally aligned with the longitudinal axis 110. When the fork-shaped member 155 rotates out of the support leg 100 (i.e., to a position substantially perpendicular to the longitudinal axis 110), it is adapted to lock into the support structure 120. The support structure 120 may, for example, be configured to hold other tools required at the work site.

[0083] Figure 12 and 13 The diagram illustrates how a fork-shaped member 155 is attached to a support structure 120. The fork-shaped member 155 includes a lever portion 155A at one end and an attachment portion 155C at the other end. A fulcrum 155B is located between the lever portion 155A and the attachment portion 155C. The support structure 120 includes a clamp 167 adapted to receive the lever portion 155A. The attachment portion 155C is connected to a floor lamp 50. The weight of the floor lamp 50 acts on the attachment portion 155C, causing the fork-shaped member 155 to rotate about the fulcrum 155B, thereby holding the lever portion 155A below the clamp 167 of the support structure 120. If the weight of the floor lamp 50 is released (e.g., by a user pulling up the floor lamp 50), the fork-shaped member 155 is released from the support structure 120, making the floor lamp 50 available for user use. Example 155 fork-shaped part is solid metal, but in other examples it can be injection-molded plastic or metal casting.

[0084] Figure 14 The user interface panel 70 on the upper component 82 is shown in more detail, and its relative position to the lamp head 55 and the auxiliary handle 80 is shown. Specific buttons on the user interface panel 70 will be shown in reference to... Figure 15 and Figure 16 A detailed explanation will be provided.

[0085] Figure 15 and 16 Various configurations of the user interface panel 70 are shown. Typically, the user interface panel 70 includes one or more buttons, one or more light-emitting diodes (LEDs), and a molded overlay covering the buttons and LEDs. Figure 15An example of the user interface panel 70 is shown, and more specifically, the differences between the pin-shaped light-emitting diodes 160C are illustrated when the floor lamp 50 is outputting various light intensity levels. Figure 15 In the example shown, high light intensity is indicated by lighting up three pin-shaped LEDs 160C, medium light intensity is indicated by lighting up two pin-shaped LEDs 160C, and low light intensity is indicated by lighting up a single pin-shaped LED 160C.

[0086] refer to Figure 16 To reduce clutter in the figures, not every button is labeled with a reference numeral, but buttons with similar icons shown in various embodiments should be understood to have the same or similar functions. In the example shown in Column I, the user interface panel 70 includes a power button 160A and an intensity button 160B. The power button 160A turns the floor lamp 50 on or off, while the intensity button 160B adjusts the light intensity level of the floor lamp 50. The buttons are made of rubber, and the icons on the buttons are printed and / or embossed. Column II shows another set of exemplary user interface panels 70 that also include a power button 160A and an intensity button 160B. Similar to... Figure 15 The needle-shaped light-emitting diode 160C is shown. The needle-shaped light-emitting diode 160C operates to indicate the current light intensity level by illuminating a plurality of needle-shaped light-emitting diodes 160C corresponding to a given light intensity level. The buttons shown in the user interface panel 70 shown in Column II are covered by individual or shared overmolded parts and are part of an embossed pad with printed buttons.

[0087] Column III shows another set of user interface panels 70, where the key difference from the user interface panels 70 shown in Columns I and II is that the power button 160A is a rotatable dial, allowing the power button 160A to be pressed to turn the floor lamp 50 on or off. The power button 160A can also be rotated to adjust the light intensity level. The power button 160A is clickable, allowing the entire power button 160A to be pressed to turn the floor lamp 50 on or off. In some examples, pin-shaped LEDs 160C indicate the relative brightness level, while in other examples, the relative brightness level is indicated via an array of LEDs 160D, which gradually illuminates above the array to indicate the light intensity level. The power button 160A may also include a braking device that provides tactile feedback to the user when the power button 160A is rotated. Similar to the buttons shown in Column II, the non-rotatable buttons and LEDs of the user interface panel 70 shown in Column III are covered by a single or shared overmolded part and are part of an embossed pad with printed buttons. The rotatable buttons of the user interface panel 70 shown in Column III can be covered by a separate overlay molding or can be a separate component.

[0088] Return to reference Figure 6 Position 50C shows the extension rod 105 of the vertical lamp 50 in its fully extended position. To achieve this, as... Figure 17-30 As shown, the floor lamp 50 includes multiple components constituting a friction-fit system 98. The friction-fit system 98 shown and described in this invention reduces or eliminates cam locks and other locking mechanisms used in similar floor lamps 50 to hold the extension rod 105 in place relative to each other and relative to the protective housing 107. This friction-fit system 98 is advantageous when using the floor lamp 50 because it is very simple for the user, as the lamp head 55 of the floor lamp 50 can be adjusted to a certain position without requiring additional locking steps to hold the lamp head 55 in place; instead, the lamp head 55 will simply remain in its positioned position.

[0089] Figure 17 A schematic example of a friction-fitting system 98 is shown. The friction-fitting system 98 includes an extension rod 105 located within a housing 107, such that the extension rod 105 can slide into and out of the protective housing 107 along a longitudinal axis 110. In other examples, a friction-fitting system is used between adjacent extension rods 105. Figure 17 A similar configuration. Bushing 106 and spring 108 are located between extension rod 105 and housing 107, such that spring 108 acts on extension rod 105 to push bushing 106 radially away from extension rod 105, thus also biasing bushing 106 radially away from longitudinal axis 110. This spring force... Figure 17 The arrow indicates the direction of friction. When the bushing 106 is pushed away from the extension rod 105, the bushing 106 contacts the housing 107, thereby generating friction between the bushing and the protective housing. The spring 108 is fixed to the extension rod 105, so the friction acts to fix or hold the extension rod 105 relative to the housing 107. The friction of the spring 108 is strong enough to support the lamp head 55, but not so strong that the user cannot overcome the friction to move the extension rod 105 (and the lamp head 55 attached thereto) relative to the housing 107. This friction... Figure 17 The middle part is indicated by an arrow.

[0090] In some examples, a plurality of bushings 106 having corresponding springs 108 are arranged radially spaced around a generally cylindrical extension rod 105, and thus the bushings 106 having corresponding springs 108 can be equidistantly spaced around a generally circular cross-section of the extension rod 105. For example, two bushings 106 and corresponding springs 108 may be located on opposite sides of the longitudinal axis 110 of the extension rod 105, respectively. In other examples, three, four, five, six or more bushings 106 and corresponding springs 108 may be arranged radially around the extension rod 105.

[0091] Figure 18 and19A An example of a friction-fitting system 98 is shown. In this example, the friction-fitting system 98 includes a bushing 170 (also called a wear-resistant sleeve or gasket) and a spring 175. In some examples, the spring 175 is a Marcel expander. The Marcel expander is a wave-shaped annular spring that may be located within a corresponding cavity 172 within the inner circumference of the bushing 170. To reduce... Figure 18 The arrangement is somewhat messy, and not all cavities 172 are labeled. The spring 175 shown in Figure 19B has no surrounding structure. In some examples, the spring 175 is metal, but in others it is formed of other materials. Return to Reference Figure 18 The spring 175 is shown as including a wavy circumference that, when located within the bushing 170 and between two adjacent extension rods 105, pushes radially outward relative to the longitudinal axis 110. This radial force causes the bushing 170 to expand into the extension rods 105 extending around the bushing 170, thereby generating friction between adjacent extension rods 105, with the bushing 170 and spring 175 located between the adjacent extension rods 105.

[0092] like Figure 18 As shown, two extension rods 105 are provided, which are telescopically received within the protective housing 107. Therefore, two bushings 170 are provided, one between the protective housing 107 and the first outer extension rod 105, and the second between the first outer extension rod 105 and the second inner extension rod 105. Each bushing 170 is provided with two springs 175, but in other embodiments, each bushing 170 may be equipped with more or fewer springs 175. In the example shown in this invention, the bushing 170 is attached to the extension rod 105 and expands radially outward via the springs 175 to cause friction against adjacent extension rods 105 or the protective housing 107. To secure the bushing 170 in the correct position relative to the extension rod 105 mounted thereon, the bushing 170 includes a post 215 and a lip 217. The post 215 is most clearly shown in Figure 19A. Figure 19BAs shown, post 215 extends through hole 220 in extension rod 105, preventing bushing 170 from moving relative to extension rod 105 to which bushing 170 is attached. Due to the high friction between bushing 170 and extension rod 105, lip 217 is provided to provide additional security in the connection between bushing 170 and extension rod 105 to which bushing 170 is attached. Lip 217 extends beyond end 219 of extension rod 105 and then radially inward toward longitudinal axis 110 above end 219 of extension rod 105. Thus, when extension rod 105 is forced back to a nested retracted position (e.g., when the floor lamp 50 is changed from position 50C back to position 50A), lip 217 engages end 219 of extension rod 105, keeping bushing 170 in the correct position along extension rod 105.

[0093] Figure 20 An alternative friction-fitting system 98 for holding extension rods 105 in their extended positions is shown, and a friction bushing 165 formed of plastic is shown. The friction bushing 165 is located between adjacent extension rods 105 and includes a portion (e.g., a protrusion 166) thicker than the spacing between adjacent extension rods 105. Because the friction bushing 165 (or at least a portion thereof) is wider than the space where it is positioned, it generates friction that holds the extension rods 105 in place relative to each other. However, the friction bushing 165 is not so large as to generate excessive friction, as the user should be able to overcome the friction generated by the friction bushing 165 to extend and retract the extension rods 105.

[0094] Figure 21A and 21B Components are shown in another embodiment of the friction mating system 98, which is similar to Figure 17-19B The friction engagement system 98 shown is different from this one. Instead of the annular Marcel expander type spring 175, a spring 180, specifically a wave washer, is used to perform this function. The spring 180 is inserted between the bushing 170 and the extension rod 105 to apply force to the bushing 170 outward or inward, thereby generating friction between adjacent extension rods 105.

[0095] Figure 22 and 23Another embodiment of the friction-fit system 98 is shown. In this example, an O-ring 185 is used instead of a ring-shaped Marcel expander-type spring 175 or a wave washer spring 180 to perform a similar function. The O-ring 185 is inserted between the bushing 170 and the extension rod 105. However, unlike the example where springs 175, 180 force the bushing 170 outward relative to the longitudinal axis 110, the bushing 170 is relatively rigid, forcing the O-ring 185 into contact with the extension rod 105 within the bushing 170. Thus, the force exerted by the O-ring 185 on the inner extension rod 105 forces the bushing radially outward relative to the longitudinal axis 110 to generate friction to retain the inner extension rod 105 relative to the outer extension rod 105, or to generate friction between the outer extension rod and the protective housing 107.

[0096] Figure 24 Another embodiment of a friction-fitting system 98 for holding the extension rod 105 in the extended position is shown. Figure 24 The friction-fitting system 98 shown utilizes a cam 190. The cam 190 is mounted to the body 60 and is rotatable about a cam rotation axis 195. The weight of the lamp holder 55 and the extension rod 105 acting in the gravitational direction 200 causes the engagement surface 210 of the cam 190 to engage the extension rod 105. In some examples, a spring 205 is provided to engage the extension rod 105 in the rotational direction (e.g., as shown in the previous example). Figure 24 A biased cam 190 is positioned (clockwise as shown). The use of a spring 205 is not essential, but it helps to create a tight engagement between the engagement surface 210 of the cam 190 and the extension rod 105. Whether or not a spring 205 is provided, after the cam 190 engages the extension rod 105, the user actuates a trigger or another element to disengage the cam 190 and move the extension rod 105 in the direction of gravity 200. Due to the shape of the cam 190 and the engagement surface 210, the extension rod 105 can move freely along the longitudinal axis 110 in the direction opposite to gravity 200.

[0097] Figure 25 It shows something similar to Figure 17 An example of a friction-fitting system 98 is shown. This system includes an extension rod 105 located within a housing 107, such that the extension rod 105 can slide in and out of the protective housing 107 along a longitudinal axis 110. In other examples, a friction-fitting system is used between adjacent extension rods 105. Figure 25A similar configuration. Bushing 106, spring 108, and seat 250 are located between extension rod 105 and housing 107, such that spring 108 acts on seat 250, which contacts extension rod 105, thereby pushing bushing 106 radially away from extension rod 105, and thus also biasing bushing 106 radially away from longitudinal axis 110. Seat 250 includes a protrusion 260 located within bore 255 of extension rod 105. Protrusion 260 serves to hold seat 250 in place relative to extension rod 105 along longitudinal axis 110. Bushing 106 also includes a protrusion 265 extending in bore 255. Protrusion 260 of seat 250 is hollow, such that protrusion 265 extends within protrusion 260 and into bore 255. Spring 108 (in this example, a generally cylindrical helical spring) is positioned around protrusion 265 of bushing 106, which is also generally cylindrical. Spring 108 is also located within protrusion 260 and extends into bore 255. Thus, spring 108 biases the interior of protrusion 260 away from bushing 106 to ultimately generate friction between extension rod 105 and housing 107 or adjacent extension rod 105.

[0098] The seat 250 also includes a lip 270 extending above and around the end 275 of the extension rod 105. When the protrusion 260 of the seat 250 is used to hold the seat 250 in place relative to the extension rod 105, the lip 270 forms a barrier such that when the extension rod 105 is pushed into the housing 107, the extension rod 105 does not move more than the seat 250 relative to the longitudinal axis 110.

[0099] Figure 26 The view along the longitudinal axis 110 is shown. Figure 25 Another view of the friction mating system 98 shown. Figure 26 The example shown includes four bushings 106 equidistant from each other in a circular cross-section surrounding the extension rod 105. However, there are only two seats 250, because... Figure 26 In the example, each seat 250 receives a combination of two springs 108 and bushings 106. In other words, the seat 250 includes a first protrusion 260A and a second protrusion 250B. The first protrusion 250A and the second protrusion 250B are radially spaced about the extension rod 105 and are received within corresponding holes 255 (in...). Figure 26 (The middle is obscured). A first protrusion 260A receives a first spring 108A, which is positioned around a first protrusion 265A of a first bushing 106A. A second protrusion 260B receives a second spring 108B, which is positioned around a second protrusion 265B of the first bushing 106B. Figure 26In the example shown, seat 250 extends about halfway around extension rod 105, and thus two seats 250 (and thus a total of four springs 108 and bushings 106) are used for extending around the entire circumference of extension rod 105.

[0100] Figure 27 It shows something similar to Figure 25 and 26 Another example of the friction-fitting system 98 shown, although with Figure 25 and 26 Compared to the examples in, Figure 27 The examples include several design variations. Hole 255 is elongated, such that the receiving portion of hole 255 along the longitudinal axis 110 is significantly longer than... Figure 25 The example in the image shows a protrusion 260. The protrusion 260 is relatively long because the seat 250 includes a first cavity 280 and a second cavity 285 formed within the protrusion 260. The first cavity 280 receives a first protrusion 265C, while the second cavity 285 receives a second protrusion 265D. Both the first protrusion 265C and the second protrusion 265D are formed on a single bushing 106. The first cavity 280 and the second cavity 285 are spaced apart along a longitudinal axis 110 (e.g., vertically spaced apart when the upright lamp 50 is in an upright position). Therefore, the first protrusion 265C and the second protrusion 265D, and the corresponding springs 108C, 108D, are also spaced apart along the longitudinal axis 110. The first protrusion 265C includes a first spring 108C positioned around the first protrusion 265C, and the second protrusion 265D includes a second spring 108D positioned around the second protrusion 265D. Similar to... Figure 25 and Figure 26 In the example shown, the first spring 108C and the second spring 108D bias the seat 250 away from the bushing 106, such that the friction between the bushing 106 and the housing 107 holds the extension rod 105 in place relative to the housing 107 along the longitudinal axis 110.

[0101] Figures 28-30 Another example of a friction-fitting system 98 is shown, which uses a linear wave spring, i.e., spring 290, instead of a spring similar to... Figure 25-27 The example shown uses a helical spring. Spring 290 is most clearly shown in the assembly view of Figure 30. (Reference) Figure 28 and 29 Spring 290 is located within retainer 295, which is located within bushing 300. Spring 290 contacts extension rod 105 to bias retainer away from extension rod 105, which in turn biases bushing 300 away from extension rod 105 to contact housing 107. Friction between housing 107 and bushing 300 serves to hold extension rod 105 in place relative to housing 107 along longitudinal axis 110. Bushing 300 includes protrusion 310, which is received within bore 315. Figure 29 In the example shown, each bushing 300 includes two protrusions 310A, 310B, which are received in corresponding holes 315A, 315B in the extension rod 105. The holes 315A, 315B are spaced apart along the longitudinal axis 110.

[0102] like Figure 29 As shown, the bushing 300 in this example includes two springs 290A and 290B and corresponding retainers 295A and 295B. More specifically, the bushing 300 includes a first cavity 305A in which the retainer 295A is located and retains the spring 290A. The bushing 300 also includes a second cavity 305B in which the retainer 295B is located and retains the spring 290B. The bushing 300 extends approximately halfway around the extension rod 105, and thus two bushings 300 (and thus four springs 290 and retainers 295) are used to extend around the entire circumference of the extension rod 105. Each of the retainers 295A and 295B includes flared portions 320A and 320B. The flared portions engage the corresponding seats 325A and 325B such that when the springs 290A and 290B radially bias the retainers 295A and 295B away from the extension rod 105, the retainers 295A and 295B engage the seats 325A and 325B of the bushing 300 to bias the bushing 300 against the housing 107 or the adjacent extension rod.

[0103] exist Figure 30 In the example shown, each bushing 300 holds three springs 290A, 290B, and 290C using three corresponding retainers 295A, 295B, and 295C. Similar to... Figure 28 and Figure 29 In the example, bushing 300 also extends about halfway around extension rod 105. Figure 30 Hole 315 is also shown, although the shape of hole 315 is similar to Figure 28 and Figure 29 The example shown is different. Figure 30 The hole 315 in the middle is rectangular, not... Figure 28 and 29 The hole 315 is generally circular as shown. The protrusion 310 is a corresponding rectangular shape so that it can be received within the hole 315 to fix the bushing 300 relative to the extension rod 105. Figure 30 Also shown are retainer cavities 330A and 330B within bushing 300. A third cavity in bushing 300 is... Figure 30 The retainers 295A and 295B are obscured. When the retainers 295A and 295B are located within the bushing 300, they extend radially inward from the bushing 300, pass through the cavities 330A and 330B, and extend radially outward from the bushing 300. This can also be... Figure 29Seen in bushing 300 shown at the top. Thus, when springs 290A, 290B push retainers 295A, 295B radially away from extension rod 105, retainers 295A, 295B and bushing 300 are biased to contact housing 107 or adjacent extension rod, which generates friction to hold extension rod 105 in place relative to housing 107.

[0104] It should be understood that the application of this invention is not limited to the details of the construction and arrangement of the components set forth in the following description or shown in the following drawings.
