Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a snooze mechanism for stopping an alarm signal in an alarm clock.

(Prior art) A snooze mechanism in the prior art is composed of three separate parts: a snooze lever, a return spring, and a snooze contact piece, and is assembled after the snooze contact piece is fixed to the snooze lever by welding or the like. It was hot.

(Problems to be solved by the invention) According to this configuration, the number of parts is large, which requires time and effort to assemble, and the snooze contact piece moves up and down together with the snooze lever, making the snooze contact piece elastic. The printed circuit board that slides in contact had to be as large as the stroke of the snooze contact.

The purpose of the present invention is to reduce the number of parts, simplify assembly, and downsize the movement to reduce costs.

(Means for Solving Problems) The feature of the present invention is that a snooze lever is supported on the housing of the alarm clock mechanical body so as to be able to slide up and down, and this snooze lever is attached to the top side of the housing. A positioned operating section, a sliding section extending perpendicularly to the operating section, and an operating protrusion projecting into the housing from the sliding section are integrally formed. The snooze spring member includes a return spring part interposed between the operating part and the upper surface of the housing, a snooze contact piece extending perpendicularly to the return spring part into the housing, and a snooze contact piece extending perpendicularly to the return spring part. It is integrally formed with an L-shaped mounting piece that extends vertically into the housing, and this snooze contact piece is pressed against the snooze contact point on the printed circuit board by the operating protrusion of the snooze lever. It is designed so that The housing is provided with a mounting protrusion that protrudes across the base of the mounting piece, and the snooze spring member is irremovably mounted thereon.

(Example) Hereinafter, an example of the present invention will be described with reference to the drawings.

1 and 2, a housing 1 of an alarm clock mechanical body is composed of a lower case 2 and an upper case 3. As shown in FIGS. The snooze lever 4 includes an operating section 4a located on the upper surface of the housing 1 and operable from the outside, a sliding section 4b extending perpendicularly from the operating section and located on the outer surface of the upper case 3, and a sliding section 4b that extends vertically from the operating section and is located on the outer surface of the upper case 3. An operating protrusion 4c protruding from the moving part toward the inside of the housing 1 is integrally formed. Guide protrusions 3a, 3 are provided on the outer surface of the upper case 3.
b, 3c, and 3d are provided in a protruding manner, and support the snooze lever 4 on the housing 1 in a vertically slidable manner. The guide protrusion 3d fits into a guide groove 4d provided in the snooze lever 4, and regulates the sliding stroke of the snooze lever 4.

As shown in the first to third figures, 5 is a snooze spring member, which includes a return spring portion 5a that is interposed between the operating portion 4a of the snooze lever 4 and the upper surface of the housing 1 and is bent in a V-shape. , this return spring portion 5a
a snooze contact piece 5b and a power contact piece 5c extending perpendicularly into the housing 1, and an L-shaped mounting piece extending perpendicularly into the housing 1 with respect to the return spring part 5a. 5d are integrally formed. This snooze contact piece 5b is operated by the operating protrusion 4c of the snooze lever 4 into the printed circuit board 6 provided in the housing 1.
The snooze contact is pressed into contact with the snooze contact. Further, the power contact piece 5c is always in elastic contact with the power contact point of the printed circuit board 6. The tips of the snooze contact piece 5b and the power contact piece 5c are bifurcated,
The snooze contact and power contact are securely connected.

The means for attaching the snooze spring member 5 to the housing 1 will be explained. As shown in the first and second figures, the snooze contact piece 5b, the power contact piece 5c, and the attachment piece 5d extend into the housing 1 through between the contact surfaces of the lower case 2 and the upper case 3, and are attached to the contact surface. It's stuck in place. Further, mounting protrusions 2a and 2b protrude from the inner surface of the lower case 2 toward the upper case 3 side, and sandwich the base of the L-shaped mounting piece 5d. For this reason, the snooze spring member 5 is restricted from moving in the horizontal direction in FIG. 2 by the lower case 2 and upper case 3, and from moving in the vertical direction in FIGS. and is attached to the housing 1 in a manner that cannot be removed.

When assembling, first assemble parts such as gears into the lower case 2, hold the snooze spring member 5 so that the base of its mounting piece 5d is located between the mounting protrusions 2a and 2b, and then attach the upper case 3 to the lower case 2. Connect to. After that, when the snooze lever 4 is slid along the guide protrusions 3a to 3c with its operation protrusion 4c protruding into the housing 1, the guide protrusion 3d fits into the guide groove 4d,
A snooze lever 4 is attached to the housing 1. In this assembled state, the power contact piece 5c is in elastic contact with the printed circuit board 6 as shown in FIG. 2, but the snooze contact piece 5b is separated from the printed circuit board 6. When the snooze lever 4 is pressed down to stop the alarm after emitting the alarm sound, the snooze contact piece 5b is pressed by the operating protrusion 4c, and the snooze contact piece 5b is pressed against the snooze contact on the printed circuit board 6, as shown by the chain line in FIG. The alarm is pressed, and the alarm sound is temporarily stopped. The snooze lever 4 is raised by the spring force of the return spring portion 5a of the snooze spring member 5, and the alarm sound is emitted again.

(Effects of the invention) The present invention is constructed as described above, and since it requires only two parts, the snooze lever and the snooze spring member, the number of parts can be reduced, and accordingly, the assembly time can be shortened, and costs can be reduced. I can do it. Since the snooze contact piece is integrally formed with the snooze spring member and does not move up and down, extra space on the printed circuit board is not required, and the watch mechanical body can be made smaller. Further, since the snooze spring member is irremovably attached simply by sandwiching the base of the attachment piece between the attachment protrusions, attachment is extremely easy.
