Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a curved fabric covering frame for an embroidery sewing machine used when embroidering on a peripheral surface of a hat.

[Conventional technology]

In a conventional bent cloth upholstery frame, as shown in Japanese Patent Publication No. 62-42066, an outer peripheral surface of a hat put on a bent upholstered frame body is fastened with an elastic string. However, there has been a disadvantage that the hat slides sideways with respect to the curved cloth-clad frame body during embroidery, causing a change in the embroidery pattern. Therefore, in order to be able to strongly press the embroidery portion of the hat and the surrounding area against the curved upholstered frame main body, two connecting mechanisms are provided on the outer peripheral side of the curved upholstered frame main body. The present inventors have proposed a structure in which a cloth presser frame is connected to the ends of these connecting mechanisms, and the peripheral surface of the hat is strongly pressed by the cloth presser frame.

[Problems to be solved by the invention]

In the above-mentioned conventional embroidery sewing machine, when the embroidery sewing is performed on the peripheral surface of the hat with the eaves, the eaves hit the connection mechanism,
When a hat with an eaves is set on the main body of the bent fabric frame, there is a problem that the eaves must be set so that the eaves do not hit the connecting mechanism. This restricts the selective placement of an arbitrary position on the peripheral surface of the hat at the needle drop position, and has a problem that the range of the embroidery scheduled portion on the peripheral surface is significantly reduced.

The present invention has been made in view of the above points, and an object of the present invention is to provide a hat with an eaves that can be crimped around a portion to be embroidered on a peripheral surface of a hat to a curved cloth-clad frame body. Provided is an embroidery sewing machine bent frame which can position an expected embroidery portion on a peripheral surface of a hat at a needle drop position without restricting the eaves of the hat by a connecting mechanism. That is.

[Means for solving the problem]

In order to achieve the above object, the present invention employs the means described in the claims, and the operation is as follows.

[Action]

The hat is placed on the curved cloth frame body so that the embroidery portion on the peripheral surface of the hat is opposed to the needle drop position, the cloth presser frame is applied to the peripheral surface of the hat, and the cloth presser frame is bent by the connecting mechanism. Fasten to the tension frame body. As a result, the periphery of the embroidery scheduled portion of the hat can be press-bonded to the outer peripheral surface of the curved cloth-clad frame main body, and the entire embroidery scheduled portion can be held in a tension state. In the case of a hat with an eaves, the eaves of the hat can be overlapped with the connection mechanism by escaping the eaves of the hat to the rear of the take-out portion of the take-out member in the connection mechanism. A wide range on the surface can be selectively positioned at the needle drop position.
