Description

[Detailed description of the invention] The present invention relates to a sewing machine table, and its main purpose is to make it extremely light and easy to take out and store the sewing machine head attached to the invention without going against the gravity of the sewing machine. Another purpose is to maintain an equilibrium state even when the oil distribution state inside the sewing machine is moved from a state of non-use to a state of use, thereby preventing oil leakage. be.

With conventional sewing machine tables, in order to take the sewing machine from an unused state to a used state, since the sewing machine is attached to the table by a hinge, it is stored suspended horizontally within the table. Because you have to pull it up with one hand, possibly against gravity,
This work was painful for many women and women who used household sewing machines.

In addition, when the sewing machine is raised from a horizontal position and placed in the upright position, the lubricating oil that had been stably collecting somewhere when the sewing machine was lying on its side will be moved to another location, causing the lubricating oil to move and cause the sewn product to leak outside. was often contaminated.

The present invention was devised to eliminate the above-mentioned drawbacks of the conventional technology, and is characterized by reducing the labor burden on the sewing machine operator when preparing to operate the sewing machine, and also eliminating the possibility of oil leakage. It is.

Next, referring to an embodiment of the present invention, Figs.
The figure shows a vertical sewing machine storage cabinet according to the present invention, where 1 and 1 are left and right side plates, 2 is a rear plate, and the rear plate 2 and the side plate 1 are connected to upper, middle and lower tier plates 3 and 4. , 5.

At the bottom, double-opening front doors 6, 6 are pivotally attached to both side panels 1, 1, and a vertical second base plate 7 is hinged to the front edge of the plywood on the middle base plate 4 so as to open horizontally. 8, and the second base plate is supported horizontally so as to be flush with the middle base plate 4 when opened.

Further, the side plate 1 is provided with a cutout portion, and a small side plate 17 that closes the cutout portion is pivotally attached.

Folding rails 10 and 11 of the sewing machine head are attached to the middle bed plate 4 and the second bed plate 7 with screws or adhesives, and the folding rails 10 and 11 of the sewing machine head are connected to both plywood boards and unfolded to be in use when the second bed plate is opened. It is fixed.

The sewing machine head 12 has a general cylindrical bed type sewing machine head placed and fixed on a horizontal base plate 13, and the cylindrical bed has a floor part 15' as shown in FIG. As shown, a pivoted auxiliary floor 15 is removably attached.

The sewing machine head 12 is provided with legs 14 having a stepped shape as shown in FIG. The small diameter portion 16 at the center is made of a material with a small coefficient of friction, such as metal or polyacetylene resin.

In addition, the rails 10 and 11 are laid so that the sewing machine head can be pulled out onto the second base plate 7 that is unfolded forward of the base plate 4 of the storage section, as shown in FIG. Part 14
The left and right frame portions 18 have an inner diameter B′ larger than the outer diameter B of the small diameter portion 16 and a surface facing the large diameter portion 22 at the upper part, and the end portions have a height t greater than the leg height t of the small diameter portion 16. The bottom part 19 is formed by a deep t'' bottom part, a shallow t' bottom part in the central part, and a bottom part 19 connected at the middle part by an inclined surface.

Near the bending part of the rail 10.11, the frames 18 on the second base plate side and the base plate 4 side are inclined to each other so that they do not interfere when the second base plate 7 is closed, and the bottom part However, different halves of the plywood side and the second base plate side are cut out.

In the embodiment of the present invention, four rails 10.11 are provided for each of the four legs, but two rails 10.11 are provided for each of the left and right legs.
It is also possible to use a common rail for books, with a total of two rails.

Further, reference numeral 20 serves as a second auxiliary floor, which is fixedly or removably attached to the back surface of the second base plate 7, that is, the surface on which the rail 10.11 is provided, and cooperates with the conventionally known auxiliary floor 15 attached to the bed. It can be used widely.

Further, when the front doors 6, 6 are opened, a driving speed controller 21 of the sewing machine is provided on the lower step plate 5.

Since the present invention has the above-described structure, in order to use the sewing machine, first open the second base plate 7 and make the base plate 7 horizontal.

Next, the sewing machine head 12 is pulled out from the storage part by lifting it slightly at first.

In the storage position of the sewing machine head 12 in the cabinet, each leg 14 of the head is at the end of each rail 10.11, and in this position the bottom of the rail is lower than the tip of the small diameter part 16.
The side surface of the large diameter portion 22 is in close contact with the frame portion 18 and the sewing machine head 12
Since it is in a state where it is subject to the full gravity of

However, if the sewing machine head 12 is moved slightly forward while still in the normal position, the tip of the leg portion 14 will rest on the shallow bottom of the rail, and the side surface of the large diameter portion 22 will be separated above the rail frame portion 18. Therefore, the contact part of the leg with the rail changes, that is, it changes from a rubber member with a high friction coefficient to a metal member with a low friction coefficient, so the sewing machine head 12 is attached to the rail 10.11.
It becomes easy to slide on the top and is easy to move.

If you pull the sewing machine head 12 toward you in this way and pull it out to the other end of the rail, the bottom of the rail will be connected to the leg 1 at the other end.
Since the height t is deeper than the height t of the small diameter portion of No. 4, the large diameter portion 22
The side surface of the large diameter section 22 is brought into contact with the rail frame 18 again, and the side surface of the large diameter section 22 receives the full gravity of the sewing machine, so that the sewing machine head can maintain a stable state in which it is placed upright in this position.

In this state, a known auxiliary floor 15 is attached to the bed 12', and a part of the auxiliary floor is unfolded, and this is connected to the second auxiliary floor 20 attached to the back side of the second base plate 7. When connected, an extremely wide sewing bed can be created.

Furthermore, if the small side plate 17 of the side plate 1 is opened, the range of sewing activities on the cabinet will be further expanded, making the work even more convenient.

Thereafter, by connecting the power supply, opening the front doors 6, 6, and operating the controller 21 as appropriate, the desired driving speed can be obtained and the sewing work can be performed.

If you want to store the sewing machine head, you can easily and smoothly store it in the cabinet by performing the exact opposite operation to the above-mentioned pulling out operation.

The present invention is as described above, and since the work of taking out and storing the sewing machine head is extremely easy, and the sewing machine head is always maintained in an upright position, the stable state of the lubricating oil is changed. There is no need to worry about oil leaks.

Also, since a second auxiliary floor is attached to the back of the second base plate, it can be connected to the conventional auxiliary floor attached to the bed to further expand the sewing floor, making it structurally simple and easy to manufacture. It is an extremely convenient idea from an industrial and practical standpoint, such as being easy.
