DEVICE FOR TENSIONING A FABRIC

RABORJI SAURABH

The invention relates to a tensioning device (1, 1 ', 1' ', 1 ''') for tensioning a web (3, 3 ', 3' ', 3'''), the device being configured to be coupled to a tensioning device (1, 1 ', 1' ', 1 ''') formed by two walls (13, 13 '; according to the invention, the walls (13, 13 ') cooperate with the grooves (9, 9') formed by the walls (13, 13 ', 15), one wall (13, 13') being smooth and the other wall (15) having at least one notched portion. The tensioning device (1, 1 ', 1' ', 1 ''') comprises: at least one member (17, 17 ', 17'', 17 ''') for holding the tensioned web (3, 3 ', 3'', 3 ''') mounted in the holding bracket (11); a body (5, 5 ', 5' ', 5 ''') and at least one stopper (7, 7 '', 7'' ', 7 '''') having a free end cooperating with the notch portion of the groove (9, 9'). The body (5, 5 ', 5' ', 5 ''') is provided with an engagement surface (29) configured to cooperate with the smooth wall (13, 13 ') of the groove (9, 9') in order to wedge the web (3, 3 ', 3' ', 3''') into the groove (9, 9 '). At least one blocking member (7, 7 ", 7" ', 7 "") is mounted for pivotal movement about an axis on said body (5, 5', 5 ", 5" ') via a pivot joint so as to be able to assume a holding position and an unlocking position, The tensioning device further comprises an elastic member (47) for pushing the blocking member (7, 7 ", 7"', 7 "") towards the holding position.

本发明涉及用于张紧幅材(3、3'、3"、3"')的张紧装置(1、1'、1"、1"')，该装置构造成与由两个壁(13、13'；15)形成的槽(9、9')配合，一个壁(13、13')是光滑的，而另一个壁(15)具有至少一个凹口部。张紧装置(1、1'、1"、1"')包括：至少一个构件(17、17'、17"、17"')，用于将张紧的幅材(3、3'、3"、3"')保持安装在固持支架(11)中；主体(5、5'、5"、5"')和至少一个阻挡件(7、7”、7"'、7"”)，所述至少一个阻挡件具有与所述槽(9、9')的凹口部配合的自由端。主体(5、5'、5"、5"')设有接合面(29)，所述接合面构造成与槽(9、9')的光滑壁(13、13')配合以便将幅材(3、3'、3"、3"')楔入槽(9、9')中。至少一个阻挡件(7、7”、7"'、7"”)安装成通过枢轴接头绕轴线在所述主体(5、5'、5"、5"')上进行枢转运动，从而能够占据固持位置和解锁位置。张紧装置还包括将阻挡件(7、7”、7"'、7"”)推向固持位置的弹性件(47)。
