Description

[Detailed description of the invention] This invention relates to an auxiliary table used in a porta-pull sewing machine, and its purpose is to substantially expand the sewing machine bed surface during use to ensure a wide workpiece fabric support surface. In addition, the auxiliary table body can always be held on the same plane as the sewing machine bed extremely stably against pressure from above, and when not in use, it can be folded compactly and stored neatly. It's about providing a table.

Hereinafter, one embodiment embodying this invention will be explained based on the drawings. In the drawing, 1 is the auxiliary table main body of this embodiment, which is divided into two parts approximately at the center shaft in the front and rear direction, and has a pair of front and rear parts. It is formed by a table plate 2°3.

Reference numeral 4 denotes a sewing machine bed accommodating part formed by cutting out one side facing part of both table plates 2.
It is adapted to be fitted into the bed 22 of No. 1.

As shown in FIG. 3, reference numeral 5 denotes a rectangular parallelepiped-shaped connection body disposed on the lower surface of the table main body 1 along the dividing line between both table plates 2 and 3, and as shown in FIGS. 4 and 5. As shown, a pair of hinges 6 are interposed between both side surfaces and the lower surfaces of both table plates 2 and 3, respectively.

Therefore, both table plates 2 and 3 are foldably connected via the connecting body 5 and the hinge 6, and when folded, the connecting body 5
is interposed between both table plates 2゜3, and both table plates 2,
Acts as a spacer to maintain the spacing between the three.

Furthermore, when support legs 10 (to be described later) support the table main body 1, a non-slip 7 attached to the lower surface of the connecting body 5 is attached to a sewing machine mounting surface 23 such as the upper surface of a sewing machine table (not shown).
The top surface has a height enough to receive the divided portions of both table plates 2.3, and supports the table body 1 in cooperation with the support legs 10.

Reference numeral 8 denotes a latch claw that is rotatably supported on the outside of the lower surface of one of the table plates 2 in the vicinity of the dividing line, and is a pin on the lower surface of the other table plate 3 when both table plates 2 and 3 are unfolded. 9 to hold it in its unfolded state.

10 is the table plate 2 at the four corners of the table body 1.
, a substantially U-shaped support leg supported by a support fitting 11 fixed to the lower surface of 3;
The table plates 2 and 3 are rotated from the lower position to the upper part inward.
The support bracket 1 can be moved between the positions along the lower surface of the support bracket 1 and
1 and held in that position.

When the supporting leg 10 is in the lower position, the bent portion 10 a formed at the tip thereof engages with the placement surface 23 and the table main body 1 is placed on the bed of the sewing machine bed 22 . It is supported so as to be positioned substantially on the same plane as the surface 22a.

In addition, when the supporting legs 10 are folded along the lower surfaces of the table plates 2 and 3, as shown in FIG. It is designed to fit within the interval secured by the body 5.

In addition, in this embodiment, a bent portion 10 is provided at the tip of the support leg 10.
In order to prevent the bent portions 10a from interfering with each other, the supporting legs 10 on the table board 2 side are positioned slightly inward from the other side, as shown in FIG. ing.

Reference numerals 12 and 13 denote a total of three latching pins that are supported and fixed by screws 15 to support fittings 14 fixed to the lower surfaces of the table plates 2 and 3 at the center of the inner end and on the open side side of the sewing machine bed accommodating section 4. It is molded from a synthetic resin having some flexibility, and as shown in FIG. When the table body 1 and the sewing machine bed 22 are placed on the same plane, the table body 1 and the sewing machine bed 22 are latched to the latching holes 24 and latching fittings 25 provided at the end and front and back sides of the sewing machine bed 22, respectively. The connection is maintained.

By loosening the latching pins 12 and 15, the amount of protrusion can be adjusted.

Now, in order to use this auxiliary table, first, both table plates 2 and 3 are unfolded, and the latching claws 8 are latched onto the pins 9.

When both table plates 2 and 3 are unfolded in this way, the connecting body 5
is connected by a hinge 6 between its both sides and both table plates 2.3, so it automatically stands up and its connecting plate 5
The upper end engages with the lower surfaces of both table plates 2 and 3.

Next, the support leg 10 is pulled downward, and the table main body 1 is moved in the direction of the arrow in FIG. 2 so that the sewing machine bed accommodating section 4 is fitted into the sewing machine bed 22. The stop pin 12 is hooked into the hook hole 24 of the sewing machine bed 22.

Then, as shown by the two-dot chain line in FIG. 4, the latching pin 12 is slightly bent to make the table body 1 slanted upward to the right, and in this state, the table body 1 is further moved in the direction of the arrow, so that the accommodating portion 4 is moved on both sides. The latch pin 13 is the latch fitting 2 of the sewing machine bed 22.
5. After being moved upward, keep it horizontal so that the latching pin 13 is latched to the latching fitting 25.

In this way, the table main body 1 is placed and supported on the placement surface 23 by the support legs 10, and its upper surface is continuous with the bed surface 22a of the sewing machine bed 22 on substantially the same plane, so that the bed surface is substantially Expanded.

In this state, the connecting body 5 stands upright, and the anti-slip 7 on its lower surface engages with the mounting surface 23, supporting the divided portions of both table plates 2 and 3 on the upper surface of the connecting body 5. Therefore, set table boards 2 and 3 so that the split part falls downward.
There is no rotation, and a stable expansion surface can be obtained.

Therefore, sewing work can be carried out efficiently using a wide and stable work cloth support surface.

Next, to remove the auxiliary table from the sewing machine 21, in the reverse order as described above, slightly lift the right end of the table main body 1 in FIG. 25 and move it to the left to remove the sewing machine bed accommodating section 4 from the sewing machine bed 22.

Then, after folding each support leg 10 to the lower surface position of the table plates 2 and 3 and removing the latch claw 8 from the pin 9, the table plate 2
, 3 are folded, the connecting body 5 is interposed between both the table plates 2 and 3, and the connecting body 5 forms an accommodation interval between both the table plates 2 and 3, and the support leg 10 forms an accommodation interval between the two table plates 2 and 3. They fit inside each other without interfering with each other.

Therefore, this auxiliary table can be folded compactly so that both table plates are parallel to each other, and neatly stored without getting in the way.

In addition, in this embodiment, the support legs 10 on the table board 2 side are arranged inwardly from those on the table board 3 side.
Even if the bent portions 10a are formed on the table plates 2 and 3, they do not interfere with each other. Therefore, it is unnecessary to make the connecting body 5 thicker in order to maintain the distance between the table plates 2 and 3. The folding thickness of the table board can be reduced.

In this way, this invention divides the auxiliary table into two parts approximately at the center, arranges the connecting body along the dividing line, and connects the connecting body and both table plates through hinges. Since the support legs are foldably attached to the four corners of the table body on the underside of the table board, when the table body and each support leg are unfolded and used, the auxiliary table body always resists the pressing force from above. The sewing machine bed can be supported extremely stably on the same plane as the sewing machine bed surface, and the sewing machine bed surface can be substantially expanded to ensure a wide workpiece support surface. Since the legs are located inside or outside of the other table plate, even though it has support legs at the four corners, when the auxiliary table is folded, both sides formed by the connecting body It is possible to prevent each support leg from abutting and interfering within the space between the table plates, which has the excellent effect of reducing the folded thickness of the auxiliary table and making the entire auxiliary table more compact. .
