DEVICE FOR FASTENING OF FLEXIBLE CLOTHES Russian patent published in 1999 - IPC

FIELD: construction engineering. SUBSTANCE: device can be used in arrangement of guarding structures made of flexible clothes, also in canopy structures and in film-covered greenhouses. Device has load-bearing member of rectangular cross-section and linear profiled member which embraces load-bearing member. Linear profiled member has hollow of rectangular normal cross-section. Linear profiled member is made in the form of base with side walls. One of side walls includes part of upper wall. Width of thus created through-slot between upper wall and second side wall - a_s is selected within limits of a > a_s > b, where a>b; a - width of load-bearing member of rectangular cross-section; b - height of load-bearing member of rectangular cross-section. Height of hollow in linear profiled member - h is selected within following limits: . Width of hollow in linear profiled member - c is selected from following ratio: . Application of aforesaid device improves reliability in fastening of flexible clothes and reduces labour-intensity in process of fastening and releasing of clothes. EFFECT: higher efficiency. 5 dwg
