摘要： A collapsible structure comprises a base member (B), a lower unit (10) comprising a first side structure (11) having a base end hinged to the base member (B) and a second side structure (16), an upper unit (20) comprising a first side structure (21) having one end hinged to an extremity of the second side structure (16) of the lower unit (10), and a second side structure (27) having one end hinged to the first side structure (16) of the lower unit (10) and the other end hinged to the first side structure (21) of the upper unit (20). The first and the second side structure (11, 16) of the lower unit (10) are laid down, the second side structure (27) of the upper unit (20) is laid down on the first side structure (11) of the lower unit (10), and the first side structure (21) of the upper unit (20) is laid down on the second side structure (16) of the lower unit (10) in a folded state for storing.

摘要： A thread pull-out mechanism for sewing machines, which pulls out a predetermined amount of the needle thread from the thread supply spool by means of an operating member interlocked with the take-up lever of the sewing machine. A turn-over member for turning over the direction of supply of the needle thread is disposed in a threading path between the thread supply spool and the tension regulating mechanism of the sewing machine to check backward movement of the needle thread in pulling out the needle thread from the thread supply spool. During the thread take-up motion of the take-up lever of the thread take-up mechanism, the needle thread pulled out from the thread supply spool is slackened so that the turn-over member will not exert a significant resistance to the needle thread when the take-up lever pulls the needle thread previously pulled out from the thread supply spool. Thus, the needle thread is pulled by the take-up lever smoothly as the take-up lever is moved upward for thread take-up motion. When the needle thread is pulled out from the thread supply spool by the operating member, the resistance exerted on the needle thread by the tension regulating mechanism acts to increase the resistance of the turn-over member on the needle thread, so that the backward movement of the needle thread is checked effectively while the needle thread is being pulled out from the thread supply spool.

摘要： A structure for securing a spindle motor (15) supported on a motor substrate (32) to a chassis (13). The motor substrate (32) and the chassis (13) are coupled by at least three coupling sections (33). At least two of the coupling sections (33) are fixed support members (33a) which hold and space the motor substrate (32) and the chassis (13) from each other at a prescribed distance. The remaining coupling section is an adjusting support member (33b) that holds the motor substrate (32) and the chassis (13) from each other at a variable distance. Rigid holding means is incorporated in the adjusting support member (33b) and holds the motor substrate (32) and the chassis (13) so that the motor substrate (32) and the chassis (13) remain rigid.
