A desktop elevator for providing a platform at an elevation adjustable by a user. The desktop elevator is positioned on a support surface and is provided with left, right, front and back frame members orthogonally attached to one another end to end. A platform is vertically adjustable to and from the support employing front and back rotatable brace members positioned on opposing frame members. The brace members together with channels, cutouts, locking pins and locking arms, enable the platform to be selectively distanced from the support upon moving the platform to and from it when locking latches are disengaged from the locking pins, the platform being drawn to and remaining adjacent to the support when pressure is supplied to the platform toward said support. |

1. A desktop elevator for providing a platform at an elevation adjustable by a user, said desktop elevator being supported on a surface sized to receive it, said desktop elevator comprising left, right, front and back frame members defining a support, said frame members being orthogonally attached end to end to one another, a platform vertically adjustable to a user selected altitude to and from said support, front and back rotatable brace members positioned on two opposing frame members, each having a first end rotatable to said platform and a second end rotatable to a frame member, springs each rotatably bridging an opposing frame member to a back rotatable brace member along its length and locking arms each bridging an opposing frame member to a front rotatable brace member, locking pins positioned proximate the ends of each of said locking arms at each of said opposing frame members and locking latches each having a pivot and releasably engageable to said locking pins, said platform being distanced from said support upon lifting said platform therefrom when said locking latches are disengaged from said locking pins and said platform being drawn to and remaining adjacent to said support when pressure is applied to said platform toward said support and said locking latches are disengaged from said locking pins, wherein said two opposing frame members are each configured with a channel, and said locking latch is configured to move along said channel. |
