Problems solved by technology

[0005] However, in order to enhance the vibration resistance (increase the strength) of the resin frame, many ribs must be provided inside the resin frame.
In this way, the molding of the resin frame becomes complicated
In addition, since the sewing mechanism is installed in the resin frame, the rib must be installed so as not to interfere with the sewing mechanism, so it is sometimes difficult to obtain the specified strength.

Embodiment Construction

[0026] The best mode for carrying out the present invention will be described below with reference to the drawings.

[0027] figure 1 and figure 2 Among them, the sewing machine 10 has a frame 20 made of resin. Resin frame 20 consists of a base portion 21 placed on a console (not shown), a foot column portion 22 erected from one end of the base portion 21, and a base portion 22 extending from the base portion 22 to the top of the base portion 21. The arm portion 23 is integrally formed.

[0028] The internal space 25 of the resin frame 20 is a single space in which the internal space 26 of the base part 21 , the internal space 27 of the leg part 22 , and the internal space 28 of the arm part 23 are connected. figure 1 and figure 2 In the drawing, the internal space 25 of the resin frame 20 is drawn in an open state, and the open surface becomes closed by a cover member (not shown in the figure).

[0029] As will be described later, the internal space 25 of the resin fra...

Abstract

The present invention provides a sewing machine comprising a resin machine integrally formed with a base part, a leg part erected from one end of the base part, and an arm part extending from the leg part to the upper side of the base part. frame, and a sewing mechanism which has a sewing function as a whole and is arranged in the space from the base part through the foot column part to the arm part, the stamped base frame corresponding to the base part, and the feet A stamped foot column frame installed on one end of the base frame corresponding to the column part and a stamped arm frame installed on the foot column frame corresponding to the arm part form a frame body. The sewing mechanism is supported in the frame. This sewing machine achieves both stabilization of the sewing mechanism and simplification of the resin frame by arranging the sewing mechanism in the resin frame.

Description

technical field [0001] The invention relates to a sewing machine, in particular to the internal structure of the frame of the sewing machine. Background technique [0002] As is well known, a sewing mechanism is provided in a frame of a sewing machine, and the sewing mechanism is supported by a reinforced resin frame as shown in Patent Document 1, for example. [0003] Patent Document 1: JP-A-2003-169989. [0004] Indeed, since the sewing mechanism is supported by the frame made of reinforced resin, the frame remains stable even if the sewing mechanism vibrates when the sewing machine is in operation, thereby avoiding problems such as changes in the needle drop position. [0005] However, in order to enhance the vibration resistance (increase the strength) of the resin frame, many ribs must be provided inside the resin frame. Thus, the molding of the resin frame becomes complicated. Also, since the sewing mechanism is provided in the resin frame, the rib must be provided ...
