Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a long strip-shaped panel mounting device for mounting a long strip-shaped panel made of synthetic resin in a device having the same.

Conventionally, in sewing machines that are capable of selectively forming multiple types of seam patterns, panels are made of synthetic resin in order to reduce costs, improve insulation, and facilitate design settings. things are being done.

However, because the panels are made of synthetic resin, they tend to expand and contract in the longitudinal direction due to temperature changes, and the number of types of seam patterns has recently increased, so the panels displaying these patterns are also becoming longer and longer. There is a tendency for the panel to become band-like, and this causes problems such as warpage and other deformation of the panel.

The present invention has been made in view of the above circumstances, and its purpose is to provide a long strip panel mounting device that can attach a long strip panel without deformation such as warpage.

An embodiment of the present invention will be described below with reference to the drawings.

Reference numeral 1 denotes a machine frame of a sewing machine (equipment) that can selectively form a variety of predetermined stitch patterns, and the upper part of the arm part 1a has an opening as shown in FIGS. 2 and 3. has been done.

As shown in FIG. 3, in the opening of the machine frame 1, a curved frame portion 2 is formed on the left side, and a mounting base portion 4 having a screw seat 3 is formed on the left side. A mounting bracket 6 having a threaded portion 5 is attached to the right side, and a frame portion 7 is formed.

Reference numeral 8 denotes a lid body, and a fitting groove 9 that continues in the left-right direction is formed in the front lower end portion extending in the left-right direction.

Reference numeral 10 denotes a plastic band-like panel that is elongated in the left-right direction, and on the front side thereof, figures 11 representing a large number of types of seam patterns are drawn adjacent to each other in the longitudinal direction, and each figure 11 is Light emitting diodes 12 are arranged in corresponding positions below.

Further, an operation button 13 for selecting a stitch pattern is provided at the right end of the strip panel 10.

Although not shown, a printed circuit board or the like is provided on the back side of the band-shaped panel 10.

The strip-shaped panel 10 has a protruding step portion 14 on its upper edge that serves as a blocking portion that fits into the fitting groove 9 of the lid 8.
A hook-shaped locking portion 15 is formed at the left end of the back surface, and a mounting portion 16 having a notch for screw insertion is formed at the right end of the back surface.

As shown in FIG. 4, the hook-shaped locking portion 15 is fitted with a protrusion 17 formed on the frame 2 of the machine frame 1 so as to be slidable in the left-right direction (longitudinal direction of the strip panel 10). A notched recess 18 is formed.

The procedure for attaching the strip panel 10 and the lid 8 will now be described.

First, the hook-shaped locking part 15 of the strip panel 10 is locked to the protruding part 17 of the frame 2 on the machine frame 1, and the mounting part 16 is fixed to the frame 7 with the screw 19 (see FIG. 2) as a fixing means. .

Next, the lid body 8 is placed so that its fitting groove 9 fits into the protruding step portion 14 of the strip panel 10, and the lid body 8 is fixed to the screw seat 3 and the threaded portion 5 with screws.

In this way, the strip panel 10 is attached between the machine frame 1 and the lid 8, and the cover 8 closes the opening of the arm portion 1a of the machine frame 1.

In this attached state, the hook-shaped locking portion 1 of the strip panel 10
5 is movable in the left-right direction with respect to the frame 2, and movement in the front-back direction is restricted, and the protruding step portion 14 is movable in the left-right direction with respect to the fitting groove 9.

The reason why the strip panel 10 is formed separately from the lid body 8 and attached to the machine frame 1 is to facilitate electrical wiring, and also to make the strip panel 10 flush with the front surface of the arm portion 1a. The reason for placing it is to improve the aesthetic appearance.

In the above embodiment, the protruding step portion 14 serving as the blocking portion is
Although it is formed on the upper edge of the strip panel 10, it may be formed on the lower edge or both upper and lower edges of the strip panel 10. In short, it may be formed on at least one end edge extending in the longitudinal direction of the strip panel 10.

Further, in the above embodiment, the fitting groove 9 is formed in the lid 8, but it may be provided in the machine frame 1 or the lid 8 depending on the position of the protruding step 14.

The pond water design is not limited to the embodiments described above and shown in the drawings, and can be implemented with various modifications without departing from the gist, for example, it can be applied not only to sewing machines but also to other devices.

As understood from the above embodiments, the present invention obtains the following effects.

That is, a blocking part is integrally formed on at least one end edge extending in the longitudinal direction of the strip panel, and the warpage of the strip panel is restricted by cooperation between the blocking part and the lid or the machine frame. Even though the panel is long, it can be reliably prevented from warping, and if the strip panel is warped, it can be installed while correcting the warp.

Moreover, on the inside of the edge in the longitudinal direction of the strip panel,
At least, a hook-shaped locking part is formed to be locked to the machine frame in order to restrict the movement of the edge in the longitudinal direction and to allow movement in the longitudinal direction, and on the other hand, it is fixed to the machine frame at one place inside the strip panel. Since the mounting portion is formed to be fixed by means, expansion and contraction in the longitudinal direction of the strip panel can be reliably absorbed, and
It is also possible to absorb dimensional errors in manufacturing between the attachment part and the hook-shaped locking part.

Moreover, according to an embodiment in which the blocking part of the strip panel is constructed from a protruding step part, and a fitting groove into which the protruding step part fits is formed in the lid body (or machine frame), the structure is simple. In addition to being a distant relative of warpage prevention, it also has a good appearance.
