DETAILED DESCRIPTION OF THE INVENTION

(6) The present invention is directed generally toward a method of switching modes of operation of a quilting, or sewing machine. More specifically, it is directed toward a method of switching modes of operation while the sewing machine is running, and wherein the modes of operation have been programmed by a user.

(7) FIG. 1 provides a perspective view of a sewing machine 1 having each of a tablet 5 for controlling the sewing machine 1 and a handle assembly 10 for operating the sewing machine. The manner in which the tablet 5 and the handle assembly 10 operate the sewing machine 1 is described in greater detail herein below.

(8) FIG. 2 illustrates an exploded perspective view of the handle assembly 10 for use with a sewing machine (not illustrated). Handle assembly 10 includes components known throughout the art including grips 20 for users to grasp in steering the handle assembly 10, a casing 30 for including operative components therein, a post 40 to which a laser may be mounted, and LED light fixture 50 for illuminating a workspace for a user. In operation, handle assembly 10 operates in a manner known in the art for quilting, both traditional long-armed stitching methods and those including a pantograph pattern, where the pantograph pattern is traced by a laser, physical pointer, or other digital means.

(9) FIG. 2 further illustrates an enclosure member 60, which may be used to contain and secure various electronic, mechanical, and digital components for operating the sewing machine. Those components may be operated by a control interface 70. Control interface 70 is illustrated in FIG. 2 as exploding from grips 20, as switches 70.

(10) Control interface 70 may include a plurality of buttons, or alternatively switches, for controlling various aspects of the sewing machine. Switches 70 are illustrated in FIG. 2 as each including two buttons 75. The means by which buttons 75 of switches 70 adjust the sewing machine features are means known in the art of electronics. For example, switches 70 and buttons 75 may be in electronic communication with a controller that adjusts the motor associated with the sewing machine to adjust stitching mode, speed, etc. (not illustrated).

(11) In the present invention, the settings that buttons 75 communicate to the controller are pre-determined by a user. Alternatively, the settings may be hard-wired and defined with factory settings. In the present embodiment, settings that the user may define include, but are not limited to, stitch speed and stitch mode (e.g. Constant, Basting, Regulated). For example, a user may define that pushing a first button 75 causes the sewing machine to switch to Constant mode at a speed of 20 stitches per inch, or alternatively, pushing a second button 75 causes the sewing machine to switch to Constant mode at a speed of 40 stitches per inch. The aforementioned buttons may be a toggled switch, such as buttons 75 of switch 70, or the buttons may be separate and independent buttons. The means by which a user may define the settings programmed for use with the sewing machine may be any means known throughout the art. For example, the settings may be programmable on a computer, tablet, or mobile device, which may then be transferred to buttons 75 via a manner known in the art, for example a USB, Wi-Fi, Bluetooth, or other connection. Alternatively there may be a control panel located elsewhere on the sewing machine for adjusting the settings associated with control interface 70. When a user pushes a button 75 of switch 70 associated with particular settings, those settings may be implemented immediately. It should be noted that the settings may be implemented immediately, without the need to stop the machine. Thus, the settings may be implemented while the machine is operating or stopped.

(12) In the illustrated embodiment, buttons 75 for adjusting settings associated with the sewing machine are embodied as switches 70, wherein each switch 70 includes two buttons 75. In other foreseeable embodiments, the buttons 75 of switches 70, or other control interface, may be located elsewhere on handle assembly 10, for example casing 30. The control interface may be placed at any location so long as it is within reach of a user. The control interface 70, such as switches 70 with buttons 75 may alternatively be located at a rear set of handles associated with a rear portion of a quilting machine that is well-known in the art for being used in tracing pantograph patterns. The preferred embodiment includes two toggle switches 70, made up of four buttons 75 (two buttons 75 for each switch 70), for controlling sewing modes. However, embodiments are further envisioned wherein more or less toggle switches and/or buttons for controlling sewing modes could be included with the sewing machine.

(13) In one embodiment, the sewing machine does not include buttons 75 for a control interface 70, and it instead includes a plurality of switches, knobs, or other foreseeable control interfaces which perform substantially similarly to the buttons 75 described herein above. In this embodiment, the switches, knobs, or other foreseeable control interfaces may also be positioned at any location associated with the sewing machine as long as they are within reach of a user.

(14) Presently, sewing machines such as those described in the present application may include tablet devices, or tablets for use therewith. In the present embodiment, a Samsung Galaxy Tab 3 10.1 Android may be used with the sewing machine. Tablets are used with sewing machines to control a sewing machine by positioning needles, operating the laser used when tracing pantograph patterns, starting and stopping sewing, and many other functions.

(15) In an alternative embodiment, the tablet may be used to control the stitching modes and speeds in the manner above in place of buttons 75 or other control interfaces 70. In this embodiment, it should be noted that the user may command a sewing machine to switch modes immediately upon direction, as previously described. Thus the modes may be switched while the machine is in operation or stopped. It should further be noted that in this embodiment, the modes which may be available to a user may be pre-set by a user. The user may define these pre-set modes using software of the application the tablet uses in operating the sewing machine.

(16) FIG. 3 is a user interface 80 of the tablet 5 as an operator may see it. In the illustrated embodiment, user interface 80 includes a top ribbon 90, where a variety of modes may be selected to automatically switch the mode in which the machine is operating, including user preset modes 100. User preset modes 100 may be programmed by the user via software associated with the tablet or in other manners known throughout the art. In the illustrated embodiment, there are two user preset modes 100 displayed, though alternative embodiments including more user preset modes 100 are foreseen.

(17) The screenshot further includes a mode section 110 where the mode in which the sewing machine is operating is displayed. A bottom ribbon 120 is also illustrated in FIG. 3. Bottom ribbon 120 allows a user to assign various button 75 functions. In FIG. 3, the functions assigned to buttons 75 are (A)ADJUST SETTING DOWN, (B)ADJUST SETTING UP, (C)START/STOP STITCHING, and (D)MYSTITCH SELECT. In the illustrated embodiment, MYSTITCH SELECT mode is preset mode 100 including speed and stitch regulating, though as set forth above the MYSTITCH SELECT mode is user programmable.

(18) In the preferred embodiment, setting (A) corresponds to one button 75 on one switch 70 shown in FIG. 2, setting (B) corresponds to one button 75 on one switch 70 shown in FIG. 1, setting (C) corresponds to one button 75 on one switch 70 shown in FIG. 1, and setting (D) corresponds to one button 75 on one switch 70 shown in FIG. 2 such that each setting corresponds to a single button 75. In alternative embodiments, there may be more settings from which to choose and/or more control interfaces 70 to carry out those settings. For example, in FIG. 4, menu 130 displays frequently used operations, or settings, that a user may select from in assigning the various button functions via bottom ribbon 120.
