Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a sewing machine capable of forming a plurality of predetermined patterns, by dividing and switchingly displaying a large number of sewing pattern displays representing the sewing method. The present invention relates to a pattern display device for a sewing machine that can effectively use the pattern display area on the front surface of the sewing machine.

In a sewing machine that selectively forms a large number of predetermined patterns, it is possible to select between a sewing pattern display group that represents patterns such as decorative patterns, and a sewing pattern display group that represents how to sew practical patterns. It is desirable that the information be displayed in In contrast, a display board on which the sewing pattern display group is drawn is placed on the front of the sewing machine, and a large number of small windows are formed to match the individual sewing pattern displays, and a cover board is placed over it. A device has been proposed that selectively switches the sewing pattern display that can be recognized through the small window by shifting the cover plate against the display plate. This is one device.

However, according to this pattern display method, all the sewing patterns are displayed on the display board placed on the front of the sewing machine, and one of the sewing patterns is covered up.
This allows effective use of the narrow pattern display area allowed on the front of the sewing machine. In other words, since the area on the display board where many sewing patterns are drawn is the pattern display area allowed on the front of the sewing machine, the part covered by the cover plate is not used for displaying any part of the pattern display area in a certain display state. It becomes an invalid part.

For example, when the cover plate is positioned at two positions and two groups of glue pattern displays are alternatively displayed, the area used for displaying sewing patterns in one display state is equal to the number of patterns allowed on the front of the sewing machine. This means that the display area is at a disadvantage.

This kind of inconvenience is particularly noticeable in electronic (computer) sewing machines equipped with electronic memory that can form a large number of patterns, and in such cases, the number of displayed sewing patterns is limited.
The size of the stiffness or stitching pattern display becomes extremely small and becomes difficult to see.

The present invention has been made against the background of the above circumstances,
It is an object of the present invention to provide a pattern display device for a sewing machine that can display a large number of sewing patterns in an easy-to-see manner by effectively using the pattern display area allowed on the front surface of the sewing machine.

In order to achieve such an object, the present invention provides an apparatus for displaying a large number of patterns consisting of first and second pattern groups through a display window on a front panel provided in a sewing machine frame, comprising: (1) the display; (2) a first display body fixed to a sewing machine frame so as to face a window, on which a sewing pattern display of the first pattern group is drawn; (2) a first display body on which a sewing pattern display of the second pattern group is drawn; f,
: a second display body; (3) a support member that movably supports the second display body between the front panel and the first display body; (4) the second display body; The present invention is characterized in that it includes a switching member connected to the support member to switch between two predetermined operating positions.

In this way, the display area of the first display body covered by the second display body is switched and changed by operating the switching member, so that the first display body and the second display body can be switched at the same time. A large number of sewing patterns drawn in an area larger than the display window are selectively displayed through the display window. Therefore,
Since the pattern display area allowed by the display window is not partially covered by the cover plate, the allowable pattern display area can be used extremely effectively, and the pattern can be drawn on a much larger area than the display window. Since one sewing pattern display is displayed alternatively, a large number of sewing patterns can be displayed (
:) for easy viewing.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a detailed explanation will be given based on drawings showing an example of the present invention.

In FIG. 1, 10 is a front sewing machine frame of an electronic sewing machine, and a pillar part and an arm part of the sewing machine.

A front panel 12 is fitted to the front and upper surface of a portion of the front sewing machine frame 10, and one of the oil surface panels 12 has a display window with a transparent plate 13 pressed against it for switching and displaying a large number of sewing patterns. 14 is formed. The area of this display window 14 approximately corresponds to the area of the t-shaped pattern display surface allowed on the front surface of the sewing machine. At the bottom of the front panel 12, ten numeric keys 16 are arranged along the longitudinal direction, and at the right end of the front panel 12, a two-digit self-segment digital display 18 and a pair of pattern selection push buttons 20. 22 are arranged. An operating lever 26 as a switching member is provided on the upper surface of the front panel 12 and protrudes through an elongated hole 24. By operating this operating lever 26, a desired number is displayed on the digital display 18. When the number is determined, one decorative pattern corresponding to that number is selected and sewn. Also,
By selectively lighting up ■/ED arranged corresponding to the practical sewing pattern display 32 by operating the pattern selection pushbuttons 20 and 22, the operation lever is instructed to turn on and the f-co is displayed on the practical sewing pattern display 32. A practical pattern is now sewn.

Hereinafter, the pattern display device which switches and displays the sewing pattern display in the display window 14 using the operation lever 26 will be described in more detail.

As shown in FIGS. 2 to 4, the front sewing machine frame 10 has an inner wall 8 separated from the front panel 12 by a predetermined gap.

4 is screwed in by screw 36. Incidentally, in the fixed display plate 34, there is only one hole 88 formed for every six practical sewing pattern displays 82 through which the light from the IED is transmitted.

A movable display board 42, which is a second display body drawn in large numbers between the fixed display board 84 and the front panel 12, is superimposed on the fixed display board 84 and placed in the r-5 position, and overlaps the fixed display board 34. It is arranged so that it can slide between the two positions.

A right support lever 48 and a left support lever 5o are pivotally attached to the back surface of the inner wall 30 by screws 44 and 46. One end of the right support lever 48 and the left support lever 50 is provided with a pin 52 and a long hole 54 into which the pin 52 engages, respectively.
is provided so that the other ends of the right support lever 48 and the left support lever 5o can be raised and lowered simultaneously. At the other ends, locking devices 56 and 58 made of synthetic resin, respectively.
The U-shaped locking parts of the locking tools 56 and 5B are provided at both ends of the movable display plate 42 through arc-shaped elongated holes 60 and 62 formed in the inner wall 8o, respectively. , = engaged with the locking holes 64, 66. That is, the movable display plate 42 is stretched between the other ends of the right support lever 48 and the left support lever 5o, and the levers 48,
It is designed to be raised and lowered as the 5Q rotates.

The U-shaped locking portions of the locking devices 56 and 5B are elastic, and regardless of the arc 1 movement of the locking devices 56 and 58, the movable display plate 42 is in tension and parallel to the vertical direction. It is ready to be moved.

The operating lever 26 has a 1-shape, and its bent portion is pivotally attached to the back surface of the inner wall 30 by a screw 68. A right support lever 48 is provided at one end of the operation lever 26 to protrude from the right support lever 48.
An elongated hole 72 is formed to engage with the retaining pin 70, and a spring 74 is installed between the pin 70 and the screw 68 to bias them in a direction to separate them. Therefore, when the engagement pin 70 moves upward with respect to the straight line passing through the screw 68 and the screw 44, the right support lever 48 moves toward the inner wall 30 according to the force of the spring 74.
When the right support lever 48 is rotated until it comes into contact with a stopper 76 protruding from the inner wall and the first engagement pin 70 moves downward from the straight line, the right support lever 48 projects from the inner wall by 3 degrees and comes into contact with the first stopper 78.

The operation of this embodiment will be explained below.

When the operating lever 26 protruding from the front panel 12 is operated to the left in FIG. The left support lever 5o that engages with the pin 52 is rotated downward. At this point, the locking tools 56 and 5 of the right support lever 48 and the left support lever 50
The movable display board 42 stretched between the display panels 8 and 8 is moved parallel downward and positioned between the front panel 12 and the fixed display board 84, and the movable display board 42 is superimposed on the entire front surface of the fixed display board 34. The state becomes fco. As a result, the pattern group displayed through the display window 14 is drawn on the movable display board 42 and represented by one decorative stitching pattern display 40, forming a single decorative pattern group. FIG. 1, FIG. 3, and FIG. 4 show this state.

Next, the operating lever 26 is operated to the right in FIG.
Then, the right support lever 48 that engages with the operating lever 26 is rotated until it comes into contact with the stopper 76, and the left support lever 50 is similarly rotated. The movable display plate 42 stretched between the locking devices 56 and 58 of the levers 48 and 50 is moved upward and guided to the inner wall surface of the front panel 12, so that the inner wall 80 and the front panel 12, while being deformed along the T-gap formed between the upper inner wall surface of the front panel 12 and the upper surface of the inner wall 30.

As a result, the movable display board 42 that had been superimposed on the front surface of the fixed display board 34 is removed, and the practical sewing pattern display 82 drawn on the fixed display board 84 is displayed through the display window 14. . The virtual line (double-dashed line) in Figure 4 is
Operation lever 26 in this state. Right support lever 48.
and the state of the left support lever 50.

In this way, according to this embodiment, a cover plate having a large number of small windows for selectively displaying sewing patterns is not used within the display window 14, which is the permitted pattern display area on the front surface of the sewing machine. Therefore, in one display state, the ineffective portion covered by the cover plate is completely eliminated, and the allowable display area can be effectively utilized. Moreover, the display area of the fixed display board 34 and the movable display board 42 are larger than the area of the display window 14.
A large number of sewing pattern displays are drawn in the area obtained by adding the display area of There is an advantage that the pattern display is extremely easy to see.

Since the front panel 12 is configured to be evacuated by being guided by the inner wall surface of the N6 panel 12 in the gap S between the front panel 12 and the upper inner wall surface, there is a retraction space corresponding to the area of the movable display board 42 on the front surface of the sewing machine. There is an advantage that there is no need to provide .

The above has been explained based on the drawings showing one embodiment of the present invention.
However, the present invention is applicable to other aspects as well.
