The cover elements are pivoted about vertical axes which extend up adjacent the rear end of the column so that the covers may be folded inwardly to encompass the sides of the sewing machine. The cover elements advantageously include inturned edges which either engage directly over a base plate for the sewing machine or over a cover for the free arm portion which extends upwardly from the base flush with the top surface of the free arm portion. The cover elements for the free arm portion may be similarly pivotally mounted about an axis which extends vertically and which is located at the rear end of the column portion of the machine.

4 Claims, 8 Drawing Figures '1 PORTABLE SEWING MACHINE AND CASE BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates in general to sewing machines and, in particular, to a new and useful portable sewing machine having case-forming elements in the form of. cover members which are hinged to the rear of the machine and which may be folded over the sides to provide a case which may be locked at the front of the machine.

2. Description of the Prior Art Sewing machines are known which include flaps which are articulated to the machine base at either the head, rear or front sides and where the flaps are foldable so that they can be folded from top position in which they form parts of the machine case down into an operating position where they form parts of a work table. Such use of these case-forming flaps as a part of a work table requires a separate flap on the head side in addition to the horizontal hinges and separate flaps on the front and rear sides of the machine because these separate flaps must have plane inner surfaces. The construction and handling of this machine are relatively complicated and the space requirement for the machine in a sewing position is relatively great and, in fact, the increase of the area formed by the work table is not always desirable.

SUMMARY OF THE INVENTION This invention relates to a construction in which case-forming elements are incorporated directly on a sewing machine frame and in which the sewing machine provides an extremely compact portable unit not only when the case-forming flap elements are brought into the case-forming position, but also in the sewing position, when the side cover portions are pivoted outwardly in a simple manipulation to place them in a position in which they require very little space. With the invention, the case-forming flaps or cover elements are pivoted about vertical axes provided on the machine column. The cover elements may be folded from a position in which the cover elements overlie the sides of the sewing machine and form an enclosing case therefor to one in which they extend outwardly on each side of the machine in an outwardly folded operative position. The cover elements work similar to a book cover and they are advantageously made with inturned edges so that they have hollow portions which accommodate racks for receiving sewing machine accessories. The hinges for the cover elements are arranged preferably on a common rear part which can be mounted directly to the column of the sewing machine, for'example.

Since no separate cover elements are required on each end of the sewing machine due to the formation of the rear column in the free arm and the top arm portions of the machine, only side flaps are provided so that the construction and handling of the sides flaps or cover elements is very simple. By pivoting the cover elements vertically to the outside which may preferably be up to about 180, the flaps can be brought completely out of the operating range of the machine in the sewing position. The space requirement for the machine in the sewing position is hardly increased, particularly not when the flaps are so designed that they can be removed, preferably as a unit if desired. Since the closed flaps extend over the head side of the machine,

they can be made in the form of a recessed or hollow body which can receive supporting brackets for acces- LII sories which may be oriented in a position for easy use when the cover flap elements are pivoted outwardly from the machine.

Accordingly, it is an object of the invention to provide an improved portable sewing machine which includes case-forming elements which are pivotally mounted adjacent one end of the machine and which may be folded inwardly to overlie the sides of the machine and form an encompassing case therefor which advantageously may be locked at the front.

A further object of the invention is to provide a caseforming assembly for a sewing machine which comprises a mounting plate which is adapted to be attached to the rear of a sewing machine and a pivotal cover carried on each side of said mounting plate which may be pivoted so the covers are brought together over each side of the sewing machine and encompass it or pivoted outwardly to open the machine.

A further object of the invention is to provide a sewing machine and case and to provide a simple caseforming element for a sewing machine, which are simple in design, rugged in construction and economical to manufacture.

For an understanding of the principles of the invention, reference is made to the following description of typical embodiments thereof as illustrated in the accompanying drawings.

GENERAL DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to the drawings in particular, the invention embodied thereinin FIGS. la, 2a and 4 6, comprises a combined sewing machine and case which includes a sewing machine portion having a base plate 10 with an upright rear column portion 1b, a usually horizontally extending free arm portion 10 at the lower end of the column and a horizontally extending upper portion 1d which extends outwardly from the upper end of the column lb toward the front and carries the needle bar 50.

which are pivotally mounted on

hinges

52 and 52 which are carried in the vicinity of the rear face of the column lb and may be carried directly on the column, if desired.

In the embodiment shown, the

cover members

2 and 2 may be oriented in a case-forming closed position, as shown in FIG. la, or they may be pivoted outwardly around the vertical hinge axis of the hinges 52 to the position shown in FIG. 2a, in which the sewing machine is opened for operation. In the closing position, the cover members 2a bear against the base plate 1a and they include intumed top wall edges 2a and side edges 2b, which overlie the top portion la and a portion of the front of the sewing machine. The rear part of the sewing machine may be provided with a separate mounting plate 20 which carry the

hinges

52 and 52, if desired. In the closed position, shown in FIG. 1a, the complete case, including the sewing machine, may be easily carried by extending a recessed handle 3 to the dotted line position in FIG. 1a, where it may be easily gripped by a persons hand.

The front end extensions 2b of the

cover elements

2 and 2 are advantageously positioned so that they overlap in the front of the sewing machine and they carry a lock 4 so that the two flaps may be locked in position. The

cover elements

2 and 2 are advantageously recessed due to the projecting edges of the top wall 20. and the side wall 2b so that they provide space for mounting brackets 56 for accommodating various sewing machine accessories.

When the lock 4 is opened, the

cover elements

2 and 2 are folded backwardly to the position indicated in FIG. 2a or even further to a position up to 180 from the closed position, the accessories in the cover are readily accessible, and the work area in front of the machine is free.

In a preferred arrangement, the invention provides sewing machine case-forming elements which include a back mounting wall portion 220 carrying hinges 60 and 62 at respective sides which pivotally support covers 2 and 2, the mounting plate 22c has an interior wall with two vertically spaced cams 5 which protrude through a vertical slot 6 of a column wall 64 of the column portion lb of the sewing machine. The inside of the column wall advantageously carries a vertically movable latch 7 having vertically spaced

openings

8, 8 which permit passage of the cams 5. The cams 5 have a groove on their underside which is engaged by the bottom edge of the latch 7 under the biasing action of a spring 9 which urges the latch 7 upwardly. In the latch position, shown in FIG. 5, the mounting plate 22c cannot be removed from the column 1b with the latch in the position engaged below the projecting cams. The upper end of the latch 7 includes a part (not shown) which can be pressed down to move the latch out of engagement with the cams 5 in order to permit release of the cams and the plate 220. With such a construction, the entire unit can be removed from the machine in the open position so that this unit can be set up within reach of the sewing station with the accessories carried within the cover being readily accessible. It is thus not necessary to have a separate accessory box provided at the upper part of the column arm and with a separate cover.

The variations of the invention which are shown in the embodiment indicated in FIGS. lb and 2b relate to a sewing machine having the identical parts as the other embodiment, but to a cover assembly, generally designated 12, having cover-forming members or flaps 42 and 42 which extend only from the top of the free arm 10 to the top 72 of the upper arm portion 1d of the sewing machine. In this embodiment, the top walls 13b and side walls 13a of the

cover members

42 and 42 provide a recessed interior for the holding of accessories 56 as in the other embodiment. In this embodiment, there is a lower set of cover members 44 and 44' which are hinged in a manner similar to the

cover members

42 and 42, but which are of an extent such that they extend between the base la and the top 70 of the free arm 1c. With the construction described in FIGS. 1b and 2b, the machine may be used as a free arm machine in which case, the

cover members

42 and 42 are opened outwardly and, in addition, the cover members 44 and 44' are also opened outwardly to the dotted line position shown to the right of FIG. 2b. When the machine is to be used as a pedastal machine, only the

upper flaps

42 and 42 need be opened and the other flaps 44 and 44' are closed, as in the position indicated in FIG. 2b. The top flanges 45 of these cover members 44 and 44' are flush with the top face 70 of the free arm 10 so that they form an increased plane work table.

As shown in FIG. 3, both of the

flap parts

42 and 42 may be mounted so that they can be removed easily for example by lifting them out of a hinge carried on a mounting plate 46 of the column 1b, if desired.

While specific embodiments of the invention have been shown and described in detail to illustrate the application of the principles of the invention, it will be understood that the invention may be embodied otherwise without departing from such principles.
