The lock assembly can include a support member defining first and second voids at opposing end portions of thereof. A first locking knob can have a first handle and a first shaft extending from the first handle. A second locking knob can have a second handle and a second shaft extending from the second handle. A first mounting fixture can be configured to at least partially surround the boom arm and defining a first hole. The first shaft can be positioned through the first void and the first hole. A second mounting fixture can be configured to at least partially surround the support and defining a second hole. The second shaft can be positioned through the second void and the second hole. ## Claims ### Claim 1 A lock assembly for a stand assembly having a supporting a boom arm, the lock assembly comprising: a support member defining first and second voids at opposing end portions of thereof; a first locking knob having a first handle and a first shaft extending from the first handle; a second locking knob having a second handle and a second shaft extending from the second handle; a first mounting fixture configured to at least partially surround the boom arm and defining a first hole, wherein the first shaft is positioned through the first void and the first hole; and a second mounting fixture configured to at least partially surround the support and defining a second hole, wherein the second shaft is positioned through the second void and the second hole. ### Claim 2 (depends on 1) The lock assembly of claim 1, wherein the first and second shafts each define threaded portions thereon that are configured to interact with threaded portions on the first and second holes. ### Claim 3 (depends on 1) The lock assembly of claim 1, further comprising: a first tip portion on the first shaft; and a second tip portion on the second shaft, wherein the first and second shafts are formed from a first material and the first and second tip portions are formed from a second, different material. ### Claim 4 (depends on 3) The lock assembly of claim 3, wherein the second material has a higher coefficient of friction than the first material. ### Claim 5 (depends on 1) The lock assembly of claim 1, further comprising: a first insert disposed within the hole of the first mounting fixture. ### Claim 6 (depends on 1) The lock assembly of claim 1, further comprising: a rib extending between the first and second voids of the support member. ### Claim 7 (depends on 1) The lock assembly of claim 1, further comprising: one or more washers positioned around the first shaft on an opposing side of the support member from the first mounting fixture. ### Claim 8 (depends on 1) The lock assembly of claim 1, wherein the first handle is over-molded onto the first shaft. ### Claim 9 (depends on 7) The lock assembly of claim 7, wherein the boom arm is configured to be compressively retained between a retaining surface of the first mounting fixture and the first shaft. ### Claim 10 A lock assembly, comprising: a support member defining first and second voids; a first locking knob having a first shaft; a second locking knob having a second shaft; a first mounting fixture defining a first hole and a first retaining pocket, wherein the first retaining pocket is configured to at least partially surround a boom arm; and a second mounting fixture defining a second hole and a second retaining pocket, wherein the second retaining pocket is configured to at least partially surround a support. ### Claim 11 (depends on 10) The lock assembly of claim 10, further comprising: a first washer positioned around the first shaft; and a second washer positioned around the second shaft. ### Claim 12 (depends on 11) The lock assembly of claim 11, wherein the first locking knob further includes a first handle and a first tip portion at opposing ends of the first shaft, the first handle formed from a first material, the first shaft formed from a second material, and the first tip portion formed from a third material. ### Claim 13 (depends on 12) The lock assembly of claim 12, wherein the third material is at least partially formed of a nylon material. ### Claim 14 (depends on 10) The lock assembly of claim 10, wherein the first mounting fixture defines a first opening and the second mounting fixture defines a second opening, the first opening having a width that is greater than a diameter of the boom arm and the second opening having a width that is greater than a diameter of the support. ### Claim 15 (depends on 10) The lock assembly of claim 10, wherein the first and second shafts each define thread portions thereon that are configured to interact with threaded portions on the first and second holes. ### Claim 16 (depends on 10) The lock assembly of claim 10, wherein the support is configured to be compressively retained between a retaining surface of the second mounting fixture and the second shaft. ### Claim 17 A lock assembly, comprising: a support member defining first and second voids; a rib extending from the support member; a first mounting fixture operably coupled with a first shaft, wherein the first mounting fixture is configured to at least partially surround a boom arm; and a second mounting fixture operably coupled with a second shaft, wherein the second mounting fixture is configured to at least partially surround a support. ### Claim 18 (depends on 17) The lock assembly of claim 17, wherein the rib extends between the first and second voids of the support member. ### Claim 19 (depends on 17) The lock assembly of claim 17, wherein the first shaft is positioned through the first void and the second shaft is positioned through the second void. ### Claim 20 (depends on 17) The lock assembly of claim 17, wherein the first and second shafts each include a threaded portion thereon that respectively interact with threaded portions within first and second holes respectively defined by the first and second mounting fixtures.
