[0019] Referring generally to the accompanying drawings, different embodiments of laser levels, such as rotary laser levels, are shown. The laser levels discussed herein include improved core structures designed to increase the durability of the laser level. For example, in some conventional laser levels, damage to the core structure, and specifically to the leveling pin, can occur when the laser level is subjected to impacts (e.g., drops of rotary laser level 10, impacts from falling tools or other debris from the work site, etc.). The applicant believes that the designs discussed herein, for example by including pin retainers connected to the leveling pin and / or providing leveling pins with the specific dimensions discussed herein, can reduce the amount of force applied to the core and / or leveling pin during impact (i.e., distributed load) and increase the durability of the core (i.e., improved maintenance of accuracy after impact). The applicant believes that the core structures discussed herein can be used to reduce damage to the core, and specifically to the leveling pin, such as bending and / or breakage damage.

[0020] refer to Figures 1 to 2 This illustration shows various aspects of a laser level, shown as a rotating laser level 10. The rotating laser level 10 includes a housing 12, a holder 14, and a laser generator 28 positioned within the housing 12 and / or the holder 14. The holder 14 includes a buffer 18 having a central aperture 20 and multiple legs 22 defining multiple openings and / or side windows 24. In a specific embodiment, the rotating laser level 10 includes multiple handles 26 coupled to the housing 12, thereby allowing for improved stability and mobility of the rotating laser level 10. Generally, the laser generator 28 includes various components for generating a laser plane associated with the laser level 10. The laser generator 28 includes a laser emitting device shown as a laser diode 30, and various optical components (e.g., lenses, collimators, mirrors, beam shapers, etc.) shown as a focusing lens 32, a wedge lens 34, a pentaprism 36, and supporting hardware (e.g., a leveling pendulum, a position sensor, an electronic controller, etc.).

[0021] The pentaprism 36 rotates clockwise and / or counterclockwise about a vertical axis shown as the central axis 16. As the pentaprism 36 rotates, a horizontal laser beam 38 is projected in a generally horizontal direction beyond the holder 14 through the wedge lens 32 and the side window 24. A vertical laser beam 40 passes through the pentaprism 36, through the wedge lens 34 and the top window 39, and is projected in a generally vertical direction beyond the holder 14.

[0022] refer to Figures 3 to 4According to an exemplary embodiment, a core structure 42 of a rotary laser level 10 is shown. The core structure 42 includes one or more core walls 43 extending along (i.e., generally parallel to) a central axis 16. The core structure 42 is positioned within a housing 12 and receives at least a portion of a laser generator 28 within a cavity 44. Generally, the core structure 42 includes two sets of leveling pins, which will be described in more detail below. Multiple sets of leveling pins allow leveling in more than one direction. The core structure 42 allows leveling in a generally horizontal direction, as indicated by arrow 56, and in a generally vertical direction, as indicated by arrow 58.

[0023] Each set of leveling pins includes a first core retaining pin 46 and a second core retaining pin 48, wherein a motor leveling pin 50 is positioned between the first core retaining pin 46 and the second core retaining pin 48. In a specific embodiment, the first core retaining pin 46 has a greater length than the second core retaining pin 48. The motor leveling pin 50 is connected via a threaded rod (shown as a lead screw 62, e.g., see...) Figure 4 The leveling pins move up and down on the leveling block 52 (in the direction indicated by arrow 58). Each set of leveling pins further includes a biasing component retaining pin 54. The biasing component retaining pin 54 is coupled to the leveling block 52 and configured to retain and / or hold a biasing component or element (shown as spring 60). The biasing component retaining pin 54 is at least partially received within the leveling block 52 and includes a total length L1. Similarly, the first core retaining pin 46 is at least partially received within a portion of the core structure 42 and includes a total length L2.

[0024] refer to Figures 5 to 7 Another embodiment of a leveling pin that can be used with core structure 42 and / or rotary laser level 10 is shown. The applicant believes that further modifications to the leveling pin increase the durability of the rotary laser level 10 by reducing the potential force applied to the assembly of leveling pins during impact events such as the drop of the rotary laser level 10, impacts from falling tools or other debris from the work site, etc. Specifically, the applicant believes that using pin retainers to distribute and / or disperse impact forces across more than one leveling pin reduces the likelihood of deformation and / or damage to the leveling pins. Generally, core structure 142 is substantially identical to core structure 42, except for the differences discussed herein. Core structure 142 is positioned within a housing (e.g., 12), and a laser generator (e.g., 28) that emits laser projection is positioned within core structure 142.

[0025] refer to Figure 5 A detailed perspective view is shown of a portion of a core structure 142 including a set of leveling pins. This set of leveling pins is coupled to the core structure 142 and configured in a first direction (i.e., a generally horizontal direction, e.g., see [reference needed]). Figure 3 Arrow 56 in the middle) or in the second direction (i.e., roughly vertical, for example, see arrow ... Figure 3 The laser generator 28 is leveled along arrow 58, with the second direction being approximately perpendicular to the first direction (i.e., 90 degrees plus or minus 10 degrees). In different specific embodiments, the first direction is approximately perpendicular to (i.e., 90 degrees plus or minus 10 degrees) the direction of Earth's gravity, and the second direction acts in the same direction as the direction of Earth's gravity (i.e., parallel to plus or minus 10 degrees).

[0026] When a second set of leveling pins is present, the first set of leveling pins levels the laser generator 28 in a first direction, while the second set of leveling pins levels the laser generator 28 in a second direction (i.e., allowing leveling in multiple directions). Apart from the differences discussed herein, the second set of leveling pins is identical to the first set. In other words, the second set of leveling pins includes a third core retaining pin, a fourth core retaining pin, a second biasing component retaining pin, and a second motor leveling pin positioned between the third and fourth core retaining pins.

[0027] The leveling pin set includes a first core retaining pin 146 and a second core retaining pin 148, wherein a motor leveling pin 150 is positioned between the first core retaining pin 146 and the second core retaining pin 148 in a second direction (i.e., vertically). In a specific embodiment, the first core retaining pin 146 has the same length as the second core retaining pin 148. In different specific embodiments, the first core retaining pin 146 extends from the core structure 142 in a first direction, and the second core retaining pin 148 extends from the core structure 142 in an orientation substantially parallel to the first core retaining pin 146 (i.e., the same orientation plus or minus 10 degrees). In such an embodiment, a biasing member retaining pin 154 extends from the core structure 142 in a second direction that is substantially perpendicular to the first direction (i.e., 90 degrees plus or minus 10 degrees). The motor leveling pin 150 extends from the core structure 142 in an orientation substantially parallel to the biasing member retaining pin 154 (i.e., the same orientation plus or minus 10 degrees).

[0028] The motor leveling pin 150 moves up and down on the leveling block 152 via a threaded rod (shown as screw 162) (in the direction indicated by arrow 158). In different embodiments, the leveling block 152 is motor-driven (i.e., motor-driven). In other embodiments, the leveling block 152 is manually movable. The set of leveling pins further includes a biasing member retaining pin 154. The biasing member retaining pin 154 is coupled to the leveling block 152 and configured to retain and / or retain a biasing member (shown as spring 160). The spring 160 is coupled to the biasing member retaining pin 154 and a second core retaining pin 148 and extends between the biasing member retaining pin and the second core retaining pin. The biasing member retaining pin 154 is at least partially received within the leveling block 152 and includes a total length L3 (e.g., see...). Figure 8Similarly, the first core retaining pin 146 is at least partially received within a portion of the core structure 42 and includes a total length L5 (see, for example, see...). Figure 9 ).

[0029] A first pin retainer 164 is connected to and configured to retain both the biasing component retaining pin 154 and the motor leveling pin 150. In other words, the first pin retainer 164 is connected to and extends between the biasing component retaining pin 154 and the motor leveling pin 150. A second pin retainer 166 is connected to and configured to retain both the first core retaining pin 146 and the second core retaining pin 148. In other words, the second pin retainer 166 is connected to and extends between the first core retaining pin and the second core retaining pin. When the first core retaining pin 146 has the same length as the second core retaining pin 148, the pin retainers 164 and 166 can more easily connect and retain the biasing component retaining pin 154 to the motor leveling pin 150, and connect and retain the first core retaining pin 146 to the second core retaining pin 148, respectively.

[0030] refer to Figure 6 A perspective view of a first pin retainer 164 according to an exemplary embodiment is shown. The first pin retainer 164 includes a body 168. The body 168 extends between a first end 170 and a second end 172. An opening or hole 174 extends through the body 168 at both the first end 170 and the second end 172 of the first pin retainer 164. Each hole 174 is sized to receive a biasing component retaining pin 154 and / or a motor leveling pin 150 when assembling the core structure 142. Each hole 174 further includes an inclined portion or an angled surface 173 that connects the hole 174 to the body 168 on at least one side of the hole 174.

[0031] refer to Figure 7 A perspective view of a second pin retainer 166 according to an exemplary embodiment is shown. The second pin retainer 166 includes a body 176. The body 176 extends between a first end 178 and a second end 180. An opening or hole 182 extends through the body 176 at both the first end 178 and the second end 180 of the second pin retainer 166. Each hole 182 is sized to receive a first core retaining pin 146 and / or a second core retaining pin 148 when the core structure 142 is assembled. Each hole 182 further includes an inclined portion or an angled surface 181 that connects the hole 182 to the body 176 on at least one side of the hole 182.

[0032] refer to Figure 8The diagram shows a cross-sectional view of a portion of the core structure 142 according to an exemplary embodiment. A first pin retainer 164 is slidable onto the ends of a biasing member retaining pin 154 and a motor leveling pin 150. An angled surface 173 provides space between the first pin retainer 164 and the biasing member retaining pin 154. An adhesive 184, schematically shown, is used to fill the hole 174 and the space created by the angled surface 173 to further secure the first pin retainer 164 to the biasing member retaining pin 154 and the motor leveling pin 150. In other words, the adhesive 184 is positioned between at least a portion of the first pin retainer 164 and the biasing member retaining pin 154 and the motor leveling pin 150. Similarly, in a different embodiment, the adhesive 184 is positioned between at least a portion of the second pin retainer 166 and the first core retaining pin 146 and the second core retaining pin 148. The spring 160 includes a connecting arm 188 at each end to engage the biasing component retaining pin 154 and the second core retaining pin 148. In a specific embodiment, the biasing component retaining pin 154 and / or the second core retaining pin 148 include a channel 186 configured to receive the connecting arm 188 of the spring 160.

[0033] The motor leveling pin 150 includes a total length L4. In a particular embodiment, L4 is greater than L3 (the length of the biasing component retaining pin 154). In another particular embodiment, L3 (the length of the biasing component retaining pin 154) is similar in length to L4 (e.g., the same length ± 0.025 inches). In such embodiments, the applicant believes that there are lengths that are significantly different from those of the biasing component retaining pin 154 and the motor leveling pin 150 (e.g., see...). Figure 4 Compared to the embodiment of pin 54 and pin 50, the first pin retainer 164 can more easily connect and / or retain the biasing component retaining pin 154 and the motor leveling pin 150.

[0034] As stated above, the applicant has determined that using pin retainers and providing specific dimensions for the leveling pins allows for improved impact performance and increased core durability (i.e., improved maintenance of accuracy after impact), while also making the leveling pins easier to engage. Specifically, the applicant believes that using pin retainers distributes and / or disperses impact forces across more than one leveling pin. For example, when the first pin retainer 164 engages the biasing component retaining pin 154 to the motor leveling pin 150, the impact forces experienced by the biasing component retaining pin 154 and / or the motor leveling pin 150 can be distributed or dispersed over the length and / or area of ​​multiple leveling pins.

[0035] In other words, when an impact force is applied to the rotary laser level 10, and more specifically to the core structure 142, the first pin retainer 164 distributes or disperses the impact force between the biasing component retaining pin 154 and the motor leveling pin 150. Similarly, when an impact force is applied to the rotary laser level 10, and more specifically to the core structure 142, the second pin retainer 166 distributes or disperses the impact force between the first core retaining pin 146 and the second core retaining pin 148. By using the first pin retainer 164 and / or the second pin retainer 166 to disperse the impact force between the biasing component retaining pin 154 and the motor leveling pin 150, or between the first core retaining pin 146 and the second core retaining pin 148, deformation of the biasing component retaining pin 154 and the motor leveling pin 150, or deformation of the first core retaining pin 146 and the second core retaining pin 148 caused by the impact force is reduced. Therefore, when the first pin retainer 164 and the second pin retainer 166 are used with the rotary laser level 10, the first pin retainer 164 distributes the force (e.g., impact force) applied to or applied to the core structure 142 between the biasing component retaining pin 154 and the motor leveling pin 150, and the second pin retainer 166 distributes the force on the core structure 142 between the first core retaining pin 146 and the second core retaining pin 148.

[0036] refer to Figure 9 The diagram shows a cross-sectional view of a portion of the core structure 142 according to an exemplary embodiment. A second pin retainer 166 is slidable onto the ends of the first core retainer pin 146 and the second core retainer pin 148. An angled surface 181 provides space between the second pin retainer 166 and the first core retainer pin 146 and the second core retainer pin 148. An adhesive 184, schematically shown, is used to fill the hole 182 and the space created by the angled surface 181 to further secure the second pin retainer 166 to the first core retainer pin 146 and the second core retainer pin 148.

[0037] The total length L5 of the first core retaining pin 146 is less than the total length L2 of the first core retaining pin 46. The total length L1 of the biasing component retaining pin 54 is less than the total length L3 of the biasing component retaining pin 154. The applicant has discovered that using pin retainers (such as the first pin retainer 164 and the second pin retainer 166) reduces the force applied to the leveling pin assembly (i.e., the biasing component retaining pin 154, the motor leveling pin 150, the first core retaining pin 146, and the second core retaining pin 148). In a specific embodiment, the applicant has discovered that deformation on individual leveling pins can be reduced by more than 50%, specifically between 70% and 80%, and more specifically about 74% (e.g., 74% ± 2%). In different specific embodiments, deformation of the biasing component retaining pin 154 and the motor leveling pin 150 caused by impact force is reduced by more than 50%, and more specifically between 70% and 80%.

[0038] In different embodiments, under impact force, the deformation is less than the maximum deformation. In different embodiments, the force experienced by each leveling pin is less than the maximum force. In different embodiments, under the impact force tested in the drop test, the force on the bias component retaining pin 154 and the motor leveling pin 150 is less than the maximum force. In different embodiments, under the impact force tested in the drop test, the force on the first core retaining pin 146 and the second core retaining pin 148 is less than the maximum force.

[0039] In a specific embodiment, the first core retaining pin 146 extends beyond the core structure 142 by a length (i.e., a distance perpendicular to the core wall in a direction away from the core wall 143) approximately the same length as the second core retaining pin 148 (e.g., the same length ± 0.025 inches). In a specific embodiment, the first core retaining pin 146 extends from the core wall 143 of the core structure 142 by a first distance, and the second core retaining pin 148 extends from the core wall 143 by a second distance, with the first distance being the same as the second distance. In such an embodiment, the applicant believes that the second pin retainer 166 can more easily connect and / or retain the first core retaining pin 146 and the second core retaining pin 148 than in embodiments of the first core retaining pin 146 and the second core retaining pin. The second core retaining pin includes a total length L6. In a specific embodiment, L6 is greater than L5.
