Abstract

A shoe 20 for a sliding and pivoting sash 12 within a window frame 10, which allows the adjustment of the spring balance 22 attached to the slide shoe using a rotating adjustment means. The shoe body 24 has a socket 26 to receive a boss mounted on the sash to enable the sash to pivot at angles ninety degrees to the slide direction. Preferably, rotation of spring attachment member 30 for tensioning the spring can be achieved without detaching the balance from the shoe. The means to rotate the attachment member 30 may have a socket 52 to receive a tool, preferably a screwdriver, which may be used to rotate the attachment point using two meshing gears 38 and 46. The rotation means may include a ratchet mechanism to permit rotation in one direction only.
