Problems solved by technology

Because the door and window pulley 100 supports the weight of the door and window sash, if the gap S is generated only on one side of the supported shaft 101, the shaft 101 will tilt and cause unnecessary tilting of the sliding wheel and the door and window sash. There is a problem that the friction of the frame of the door and window becomes larger

Abstract

Provided are a door and window pulley and a door and window in which sliding wheels are not prone to unnecessary inclination. The door and window pulley includes: a first frame, which has a pair of first opposing wall portions opposite to each other with an interval therebetween; a plurality of pulley shafts, which are straddled between the pair of first opposing wall portions, and inserted through the pair of first opposing wall portions. Any one of the first relative wall parts in the opposite wall parts is riveted and fixed on the other first relative wall part; the sliding wheels are supported by the pulley shafts to rotate freely and roll on the guide rails; A pair of second opposing wall portions opposite to each other at intervals, a first frame is arranged between the pair of second opposing wall portions; Any one of the second opposite wall parts is riveted and fixed to the other second opposite wall part, and the first frame is supported to swing freely. The pulley shaft and the swing shaft are riveted and fixed to opposite wall portions on different sides along the axial direction of the pulley shaft and the swing shaft.

Description

technical field [0001] The invention relates to a door and window pulley which is guided by a guide rail and supports a door and window sash so that it can move, and a door and window. Background technique [0002] As a door and window pulley and a door and window that are guided by guide rails and support the door and window so that it can move, for example, a door and window pulley is known, including: a sliding wheel frame and a sliding wheel, which are arranged in a housing in a housing (housing); and An adjustment mechanism is provided between the sliding wheel frame and the casing (for example, refer to Patent Document 1). In the door and window pulley, the sliding wheel is assembled between the front and rear frame walls of the sliding wheel frame, and the shaft end of the pulley shaft inserted through the hole of the sliding wheel and the sliding wheel is riveted and fixed to support the sliding wheel so that it can rotate freely. In addition, the sliding wheel fram...
