Description

[Detailed description of the invention] Technical field The invention consists of a flat table that can be used as a study table, an ironing table, a cutting table, etc., a board on which the sewing machine head is placed, and a sewing machine head. A multipurpose sewing machine table that can be switched to either a sewing machine table or a sewing machine table that has a three-dimensional structure with a movable plate that allows the work surface to float at almost the same height as the bed surface of the sewing machine. It is related to the structure of

Purpose The purpose of this invention is to provide a table that can be expanded into a single flat board that can be used as a cutting table, etc.
The table has a structure that can be switched to either a three-dimensional table with two levels of different heights so that it can be used as a sewing machine table, and the table can be used for multiple purposes. Another purpose is to connect the auxiliary bed to the cylindrical bed of a free-arm sewing machine, and by attaching a spacer to the sewing machine heads of at least two models with different total bed widths, the sewing machine bed can be adjusted. The space created between the sewing machine and the table is compensated for, so that one type of table can be shared by multiple different types of sewing machine heads.

Conventional technology Conventional sewing machine tables, especially those for free-arm sewing machines, are sometimes used with the free arm or with an auxiliary floor attached, so the movable plate of the table has a A recess is formed to accept the bed in order to facilitate the connection of the sewing machine, but since there are various bed widths on the sewing machine side, the width of the recess is made to accommodate the largest flat bed width. Therefore, when a sewing machine with a small bed width is installed, a large gap is created between the sewing machine and the bed, resulting in an unsightly defect as a product.

Configuration The present invention has been provided to eliminate the drawbacks of the prior art, and embodiments of the present invention will be described below with reference to the drawings.

Reference numeral 1 denotes a base plate, which is supported horizontally by foldable legs 2, 2, 2, and serves as a stand on which the sewing machine head M can be placed. Two U-shaped support members 4, 4 are rotatably supported under the auxiliary board 3 integrally fixed to the board, and movable plates 5 are attached to the surface of the board 1 at each end. The movable plate is mounted so that it is always parallel to the substrate 1, and the movable plate is configured so that it can be placed in either a high position shown by a solid line in FIG. 2 or a low position shown by a chain line in FIG. The position is determined by standing the stopper seat S provided on the underside of the movable plate 5 upright so as to match the height of the bed surface of the sewing machine head placed on the machine head (see Figure 2). It is lowered to a height and is brought into close contact with the auxiliary substrate 3 fixed to the substrate 1 so as to form a single plate in combination with the substrate 1.

On the side edge of the movable plate 5 facing the substrate 1 side, there is a
Recess 6 formed with dimensions that correspond to the standard width of the flat bed of the sewing machine head specified by JIS standards.
At the high position shown by the solid line in FIG. 2, the cylindrical bed F of the sewing machine head placed on the board
The bed with the auxiliary bed T connected to it is fitted into the recess 6 of the movable plate 5, making it easy to handle large cloths on the table surface with the width of the movable plate added.
When the movable plate 5 is set at the low position shown in FIG. 1, a convex portion 7 formed on the side edge of the substrate 1 facing the movable plate 5 is fitted into the concave portion 6. The width of each of the concave portion 6 and the convex portion 7 is formed such that the width on the convex side is appropriately smaller, and as shown in Fig. 1, the concave portion and the convex portion have their respective side surfaces in close contact with each other on the front side and a space on the opposite side. It is placed off to one side so that A plurality of grooves 10, 10 each having a trapezoidal cross-sectional shape are formed at the end 8 on the side of the protrusion 7 of the substrate 1 and the end 9 on the side of the recess 6 of the movable plate 5, which are opposite to each other in the longitudinal direction of the space. is provided.

Reference numeral 11 denotes a spacer, which compensates for the space created by the difference in width between the convex portion 7 of the substrate 1 and the concave portion 6 of the movable plate 5, and has approximately the same thickness as the substrate 1, and has a spacer shown in FIGS. 4 and 5. It has a rectangular shape as shown in , and one side is provided with a plurality of protrusions 12, 12... having a trapezoidal cross-sectional shape that can be fitted into the grooves 10, 10... of both the ends 8, 9. ing.

Function Since the present invention has the above-described configuration, the total width of the bed, which is a combination of the cylindrical bed F of the free arm type sewing machine head M and the auxiliary bed T attached to the bed, is
In order to share a sewing machine table with the above-mentioned structure with two types of sewing machine tables: one with the standard size defined by JIS (M') and one with smaller dimensions (M''), the overall width of the bed should be the standard size. When M' is assembled with a sewing machine table, the protrusions 12, 12, . . . are formed in the grooves 10, 10, .
..., and when combining the sewing machine table with M'' whose total bed width is smaller than the standard size, use the spacer 1 as shown in Figures 5 and 6.
In either case, if the direction of the protrusion 12 of 1 is changed by 180 degrees and inserted into the grooves 10, 10... formed in the end 9 of the movable plate 5 on the side of the recess 6, and the protrusion 12 is installed so as to be brought into close contact with the movable plate 5, Movable plate 5 and substrate 1
It is possible to compensate for the space created by

Effects Since the present invention operates as described above, when the sewing machine table is used in combination with at least two types of free arm type sewing machine heads having different total bed width dimensions, the spacer The space on the substrate or movable plate can be compensated for, and the compensation operation is extremely easy as it only involves inserting the protrusion of the spacer into the groove formed in the end of the side surface of the substrate or movable plate. Since the installation is a horizontal insertion type, it has a strong structure that prevents the spacer from falling off even if a load is applied to the installed spacer, which is highly effective in industrial use.
