Abstract

PURPOSE:To prevent the malfunction of a push button by placing the outer edge of the push button on the inside of the outside face of a peripheral wall. CONSTITUTION:A peripheral wall 3 is fitted to the outside peripheral face of a watch case 1. After a push button 4 is fitted to a groove 5 which is provided in the peripheral wall 3 and is opened to one vertical direction, the peripheral wall 3 is rotated with a finger to insert the push button 4 to a recessed detaining part 6 formed on the side part of the groove 5. Simultaneously, the recessed detaining part 6 detains the push button 4. Since the outer edge of the push button 4 is on the inside of the outside face of the peripheral wall 3, it does not projects, from the outside face of the peripheral wall 3. Thus, the peripheral wall 3 protects the push button 4 to prevent the push button from being pushed with an arm, and the malfunction is prevented.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a watch with a protector that protects the push button of a watch such as a chronograph incorporating a stopwatch for measuring time intervals. It is.

Conventional technology A watch incorporating a conventional stopwatch has a crown that protrudes from the outside of the watch case to change the hands and date display, and a push button to start, stop, and return the stopwatch to zero. What has been done is known.

The present invention also includes a watch case having an inwardly downwardly inclined portion formed on the outer circumferential surface, and a watch protector that is removably attached to the watch case and has a locking portion that is locked to the sloped portion of the watch case. A wristwatch protector mounting structure has been proposed in Japanese Utility Model Application Publication No. 63-83694, which is made of an elastic material and has a convex portion on a part of the elastic material to enable attachment and detachment from the wristwatch. A cover has been proposed in Japanese Utility Model Application Publication No. 55-1.00190.

Furthermore, a swinging arm is integrally provided on the side of the cover body that can cover the surface of the wristwatch, and a locking piece that fits into the coupling hole of the wristwatch is protruded from inside the tip of the swinging arm. Utility Model No. 5C)-97461 discloses a wristwatch cover which has a tongue piece for opening and closing on the opposite side of the swinging arm, and a fitting piece that fits externally onto the watch body and is integrally attached to the cover body. It is proposed as a public notice.

Problem to be Solved by the Invention However, in conventional watches incorporating a stopwatch, the push buttons are exposed outside the watch case, so the push buttons may be pressed by the arm, resulting in malfunction of the push buttons. This caused problems with measurements, and also placed restrictions on the design of the watch case.

Furthermore, the device described in Japanese Utility Model Application Publication No. 63-83694 is a device in which the protector is fitted onto the wristwatch case from above, so that the protector only protects the wristwatch case; In this case, a case cover made of an elastic material is fitted onto the wristwatch from above, and the case cover only protects the wristwatch. , the cover body covered the surface of the wristwatch from above, and the watch was only protected by the cover body.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned problems by locating the outer end of the push button inwardly than the outer surface of the circumferential wall of the protector so that the push button does not protrude beyond the outer surface of the circumferential wall of the protector. is reliably protected by the surrounding wall of the protector, eliminating the need to press the push button with the arm and preventing the push button from malfunctioning.There are no restrictions on the design of the watch case, and the push button of the watch case can be placed in the groove of the protector's surrounding wall. A watch with a protector that allows the protector to be easily attached to the watch case by simply inserting the protector into the watch case and rotating the circumferential wall of the protector with your finger against the outer circumferential surface of the watch case, the push button will enter the recessed locking part. Our goal is to provide the following.

Means for Solving the Problems The present invention provides a watch with a protector in which a protector is attached to a watch case, in which the protector is provided with a peripheral wall that fits on the outer circumferential surface of the watch case, and that protrudes outside the watch case. A push button is provided that is located inward from the outer surface of the peripheral wall of the protector, and a groove that opens toward one side in the vertical direction is provided in the peripheral wall of the protector. The push button is characterized in that a recessed locking portion is formed along the recessed locking portion, and the push button is locked in the recessed locking portion.

During operation, the circumferential wall formed on the protector attached to the 84 case fits into the outer circumferential surface of the watch case, and the push button located inward from the outer surface of the protector's circumferential wall protruding from the outside of the watch case is inserted into the circumferential wall of the protector. After fitting into the groove that opens toward one side in the vertical direction, rotate the circumferential wall of the protector with your finger against the outer circumferential surface of the watch case, and the push button will fit into the side of the groove in the circumferential direction of the circumferential wall. The recessed locking portion locks the push button, and is positioned inward from the outer edge of the push button or the outer surface of the circumferential wall of the protector. The push button is protected by the peripheral wall of the protector without protruding from the outer surface, and the push button is not pressed by the arm, thereby preventing the push button from malfunctioning.

EXAMPLES Hereinafter, examples of the present invention will be described in detail based on the drawings.

In FIG. 1, 1 is a watch case; watch case 1
As shown in FIG. 2, a protector 2 made of synthetic resin made of plastic is attached from below, and the protector 2 has a plurality of peripheral walls 3, 3 formed thereon that fit onto the outer peripheral surface of the watch case 1.
