FIG. 8 shows a section through the main part according to FIG. 7

In Fi ^. 1 shows a suitcase sewing machine, the bed 1 of which has a spacious recess 2 on the front, in which an accessory box A is detachably housed. This accessory box A has a bottom 5 »front and rear walls 4, 5» end walls 6 and a hinged lid 7 ', with two lugs 10 formed at the rear end on both sides of the inner surface of the lid 7, from which short pegs 11 extend outwards extend and are rotatably inserted into recesses in the upper rear end on the inside of the end walls 6, so that the cover 7 can be moved up and down about the pin 11. From the lower rear end of the end walls 6 of the box A, concentric pegs 8 extend on the outer surface, with projection 9 also being formed on both end sides 6, which extend parallel to the rear wall 5 and. when tucked underneath position \ r he box A (Fig. 3) in the? Level of the horizontal of the pin 8 or eisas extend higher. M.

The two end faces 12 of the recess 2 have Vertiefun-P ^- en, into which the Zspfen 8 with their ends freely engage both sides of the inserted between the sides 12 A box. At _c the lower front of the sides 12 bearings 14 are provided which open upwards in the plane of the sides 12, the two pins 8 of the accessory box A being rotatably engageable in these bearings. As soon as the box A is in its position as an auxiliary bed (FIG. 2), the projections 9 of the box A rest on seats 13 on the sides 12.

On both sides of the back of the above recess 2

Orderly cover plate 15, pins 16 are formed which are rotatable in bores in the rear upper end of the sides 12 engage so that the cover plate 15 around the fence 16 is rotatable.

The cover plate 15 is essentially in the plane of the top of the bed 1, with the lid 7 of the box A in the pulled-out position shown in FIG. 2 essentially is on the same level as bed 1. With its front edge, the cover plate 15 engages on the back of the Lid 7 i £ t a recess 7 ', so that the lid 7 and the cover plate 15 are aligned with one another.

The one at the top when the box A is pushed in Surface of the front wall 4 is deepened and has on its "leading edge an Anaatz 4 'so that in this position it extends below the top of the bed 1, the surface of the above the wall 4 folded cover plate 15 and the bed 1 in one plane lie.

In the embodiment of FIG. 2, the box A can by pressing on the gate 17 at the right rear end the cover plate 15 and pulled out by turning it slightly and then pivoting the box about the pin 8 be, pulling on the approach 4 'according to FIG. When the box A is pulled out, the one behind it becomes Recess 2 covered by the cover plate 15, and the lid 7 forms part of the bed 1 on a plane with the Cover plate 15 »with the top of the lid 7 of the accessory box A widening the area of the bed and in this position can be opened to remove accessories from box A.

In this position the preload 9 rests on the seat 12, and the pins 8 are in the bearing 14, so that the box A is supported in two places and even during the

Sewing with the pressure acting downwards, smoothly in their position ' remains.

To remove the box A in this position, the The pin 8 can easily be lifted out of the bearing 14, and by lifting the projection 9 along the seat 13, the box is made A easily detachable from the bed of the machine.

To accommodate the box A in the recess 2 of the bed, the cover plate 15 is turned upwards, the box A is pivoted backwards around the pin 8 and in this way inserted into the recess of the machine bed, with an angle of 90 Is rotated, as can be seen from Pig. 3. The cover 7 on the back, the bottom 3 on the front and the front wall 4 to lie on top, so that when the cover plate is folded over the front wall 4, the top of the cover plate 15 and the surface of the bed 1 lie in one plane. In this position the projection 9 comes to rest against the lower edge 12 'of the wall 12, and the rear wall 5 rests on the floor of the bed 1 so that the box A assumes a stable position. The side auxiliary bed 18 is hinged to the left of the machine bed on its upper side, and as soon as the bed 18 is pivoted into its horizontal position, it extends M substantially in one plane with the machine bed. In this position, the side auxiliary bed 18 is supported from below by an arm 22 which is rotatably attached to the left of the bed 1 and is rotatable in a constant direction by the action of a spring 21, the further rotation of the arm 22 after a rotation of 90 ° opposite the side surface de; -; Machine bed is prevented by a stop 23 on the underside of the bed 18. The auxiliary bed 18 is then secured in its position, and as soon as the aim 22 is pivoted about the left end of the bed 1, the auxiliary bed 18 folds down by 20.

In the embodiment according to. 5 and 6, the accessory box B can be pulled out forwards without rotating. The box _T tel B has a bottom 101, a front wall 102, a rear wall 103, end walls 104 and a cover 105, which is bent downward on its rear edge, with pegs 106 on its outside left and right generally in the bores are rotatably engageable at the rear end of the end walls 104 so that the cover 105 can be moved around the pin 106.

On the outside of both end walls 104 of box B, two pegs 107 are provided at the upper rear end, which can be engaged in L-shaped guide grooves 109 which extend backwards from the front of both end walls of recess 2 and open upward ends (as can be seen clearly in Figure 6) A protrusion 108 extends substantially horizontally in both end walls of the box B and is formed above the seat 110 which extends substantially horizontally along both ends 116 of the recess 2. Moving the pins 107 horizontally within the reach of the guide grooves 109, there is a part of the protrusions 108 always on the seats, whereby the relative position and the horizontal length dee protrusion 108 and the seat are fixed.

At the upper end of the recess 2, a cover plate 111 is attached, which can be folded through the engagement of the pins 112 on both sides of the cover plate 111 in bores 115 on the upper rear side of the end faces of the recess 2. In its closed position, the cover plate is flush with the top of the machine bed and covers part of the lid 105 of the box B, which is recessed by the thickness of the cover plate 111, the front side of the lid 10 ¹ ^ over its attachment 113 with the top of the cover plate 111 is aligned.

If the box B is pushed into the recess 2, so The top of the cover plate 111 and the front edge of the cover 105 extend substantially in alignment with it the top of the machine bed, as can be seen from Fig. 5, and the visual impression is in no way impaired. For pulling out the accessory box B into place The cover plate 111 is folded up as an auxiliary bed and pulls out the box B with the pin 107 running along the horizontal portion of the guide grooves 109 slides and the projections 108 on the seats 110 move forward. The pin 107 stops moving at the kink of the guide groove 109, and the cover plate 111 is closed, the end of the cover plate 111 and the engagement point 114 on the cover 105 cooperate and prevent the box B from shifting forwards or backwards. Since the depth of the engagement point 114 in substantially corresponds to the thickness of the cover plate 111, the box B and the machine bed extend at Use of the box B as an auxiliary bed essentially in one plane, so that there is no impairment when sewing.

If the box 'B is as shown in FIG. 5 according to the dashed line When the line is drawn out, the lid 105 can be easily opened and the contents of the box B are light accessible.

In the embodiment of FIGS. 7 and 8, the cover plate 111 and 15 of the previous embodiments are replaced by an extension of the machine bed 2. The accessories box el C, like the other boxes, has a bottom 201, a front wall 202, a rear wall 203, End walls 204 and a hinged cover 205. With the box 0 pushed underneath, as in Fig. 8 ■ fully awarded, both end walls, the back wall · , 'and the bottom with the exception of the front wall under the cover plate 206 of the machine bed added. Two approaches

The thickness of the cover plate 206, which is part of the recess 2 and extends from the machine bed 1, is thinner than that of the other parts of the machine bed, by φ the difference in height between the cover plate 206 and the To keep cover 205 as low as possible.

To use box C as an auxiliary bed, the The box is pulled out until the pins 207 reach the inflection point of the L-shaped guide grooves 209. The length of the Seats 210 are dimensioned in such a way that in the above example the projections 208 always rest with part of the seats 210.

The accessory box G can be opened by sliding it into the in Fig. 8 position shown in dashed lines and subsequent lifting from the machine.
