Abstract: A theater chair is removably mounted to the floor of a theater so that it may be quickly removed when needed to provide space for a patron using a wheelchair. A tool is required to remove the chair from its mount. Holes are formed in the floor of the theater, and each hole is covered with a cover plate. A base plate has a pair of ears attached to its leading edge that engage the front cover plates to hold down the front of the base plate. Rear foot anchors are mounted to the trailing edge of the base plate and these rear foot anchors releasably engage the rear cover plates to hold down the back of the base plate. The rear foot anchors are movably mounted and release the rear cover plates when moved by the tool. The tool includes an elongate rod at the end of a handle so that when the handle is rotated rearwardly, each rear foot anchor is displaced and releases its associated rear cover plate so that the chair can be detached. The chair is also easily reinstalled with the aid of the tool.

Abstract: A chair is removably mounted to the floor of a theater or other assembly hall so that it may be quickly removed when needed to provide space for a patron using a wheelchair and quickly reinstalled afterwards. Holes are formed in the floor of the theater, in a generally square pattern, and plugs are positioned in each hole. A baseplate upon which the chair is permanently mounted has plug-engaging members depending from its underside. The forward plug-engaging members slidingly engage the forward plugs, and the rearward plug-engaging members are biased to latchingly engage the rearward plugs. A special tool is inserted through access holes in the base plate to overcome the bias and disengage the rearward plug-engaging members.
