1 Claim. (Cl. 24--243)
This invention pertains to new and improved shade
The term “shade pull” is commonly used at the present
time to designate comparatively small structures which
stated in essentially summary form that it includes shade
pulls, each of which is formed of a single unitary body
of a rigid material. Such a body includes opposed side
walls joined together by an end wall so as to have a gen
erally U-shaped appearance when viewed from one end.
These side walls are formed so that the portions of them
adjacent to the end wall, and the end wall itself, are
curved in order to de?ne an internal slot leading between
the sides of a shade pull of this invention, this internal
slot being of approximately the same dimensions as the
