Abstract
The disclosure describes a non-swiveling pneumatic lectern with a base, a hollow column secured to the plate, a sleeve secured to the interior of the column, an adjustable tube having an upper end and a bottom end wherein the first end slides inside the sleeve secured to the column, a pneumatic cylinder disposed within the column for vertically moving the support, an actuation device for engaging and disengaging the pneumatic cylinder, a locking knob for locking the tube at a designated height by pressing the sleeve against the tube, and a top lectern section with a pivotable shelf.
Claims35
A non-swiveling pneumatic lectern comprising:
- a. a base;
- b. a base plate secured to the base;
- c. a hollow column secured to the base plate;
- d. a sleeve secured to the interior of the column;

- f. a pneumatic cylinder disposed within the hollow column for vertically moving a support;
- g. an actuation device for engaging and disengaging the pneumatic cylinder;
- h. a locking knob for locking the adjustable tube at a designated height by pressing the sleeve against the adjustable tube;
- i. a front panel secured to the support;
- j. a right side panel secured to the front panel and the support;
- k. a left side panel secured to the front panel and the support;
- l. a pivotable shelf comprising:
- i. a shelf top;
- ii. a shelf bottom;
- iii. a shelf front;
- iv. a shelf back;
- and
- v. wherein the shelf front is connected to the front panel and the pivotable shelf fits within the right side panel and left side panel.
A non-swiveling pneumatic speaker stand comprising:
- a. a base;
- b. a base plate secured to the base;
- c. a hollow column secured to the base plate;
- d. a sleeve secured to the interior of the column;
- e. an adjustable tube with an upper end and a lower end wherein the lower end slides inside the sleeve secured to the hollow column;
- f. a support plate attached to a support for receiving the upper end of the adjustable tube, wherein a support comprises
- i. a support top;
- ii. a support bottom;
- iii. a support front;
- iv. a support back, and
- v. wherein the support is fixed on a wedge that has an angle from the plate;
- g. a pneumatic cylinder disposed within the hollow column for vertically moving the support;
- h. an actuation device for engaging and disengaging the pneumatic cylinder;
- and

A non-swiveling pneumatic lectern comprising:
- a. a base;
- b. a hollow column and adjustable tube coaxially aligned about an axis and operatively connected in telescopic relation, one of said column and said tube connected to the base;
- c. a sleeve connected to the interior of the column;
- d. a pneumatic cylinder disposed within the hollow column that supports a lectern at a designated height in relation to said base;
- e. an actuation device that engages and disengages the pneumatic cylinder;
- f. a lock that locks the adjustable tube at the designated height in relation to the sleeve in the hollow column;
- wherein said hollow column and said adjustable tube are not rotatable in relation to each other around said axis.
