Chair heating / cooling attachment

Abstract

A chair attachment for enclosing a source of warm or cool air beneath the chair includes a skirt for surrounding the legs and back of the chair. The skirt includes a front flap, side walls and a rear wall spaced apart from the chair back connected to the back edges of the side walls. The height of the rear wall is greater than that of the side walls for extending upwardly from the bottom of the side walls to the top of the chair back. Vents between the sides of the chair seat and the side walls and between the chair back and the rear wall of the attachment permit hot or cold air to flow from beneath the chair upwardly creating walls of warm or cold air around the sides and back of a person sitting in the chair.

1 . An attachment for facilitating heating or cooling of an occupant of a chair having a seat, back, spaced apart legs extending downwardly from the seat, and arms extending outwardly and downwardly to the front of the seat comprising:
 a skirt for defining an at least partially enclosed area beneath the seat, the skirt including a pair of side walls and a rear wall, the rear wall having a height greater than the height of the side walls for extending upwardly to proximate the top of the chair back;   whereby, when the side walls are connected to the chair arms and the top of the rear wall is connected to the top of the chair back at spaced apart locations, and a source of heat or cold is placed beneath the chair seat, hot or cold air can flow upwardly through vents between the chair and the attachment to heat or cool an occupant of the chair.   
     
     
         2 . The attachment of  claim 1 , wherein said skirt includes a front flap for permitting access to the area beneath the seat. 
     
     
         3 . The attachment of  claim 2 , wherein the side walls include triangular upper ends with rear ends having the same height as the rear wall, and front ends having the same height as the flap. 
     
     
         4 . An attachment for facilitating heating or cooling of an occupant of a chair having a seat, back, spaced apart legs extending downwardly from the seat, and arms extending outwardly and downwardly to the front of the seat comprising:
 a skirt for extending around the legs of the chair to define an enclosed area beneath the seat, the skirt including a pair of side walls, a rear wall, and a front flap permitting access to the area beneath the seat, the rear wall having a height greater than the height of the side walls and flap for extending upwardly to proximate the top of the chair back;   whereby, when the side walls are connected to the chair arms and the top of the rear wall is connected to the top of the chair back at spaced apart locations, and a source of heat or cold is placed beneath the chair seat, hot or cold air can flow upwardly through vents between the chair and the attachment to heat or cool an occupant of the chair.   
     
     
         5 . The attachment of  claim 4  wherein the side walls include triangular upper ends with rear ends having the same height as the rear wall, and front ends having the same height as the flap. 
     
     
         6 . A collapsible chair comprising a skeletal, foldable frame, a flexible, one-piece seat and back mounted on said frame, and an attachment for facilitating heating or cooling of an occupant of the chair including a skirt for extending around the legs of the chair to define an enclosed area beneath the seat, the skirt including:
 a pair of side walls connected at front edges to the sides of the chair seat, a rear wall and a front flap permitting access to the area beneath the seat, the rear wall having a height greater than the height of the side walls and the flap for extending upwardly to proximate the top of the chair back and the rear wall having a top edge connected to the seat back at spaced apart locations,   whereby, a source of heat or cold is placed beneath the chair seat, hot or cold air can flow upwardly through vents between the chair and the skirt to heat or cool an occupant of the chair.
