Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a portable instrument case suitable for application to a pedometer or the like that measures the number of steps taken.

[Prior art] A pedometer is attached to a band or the like and records the number of steps taken by vertical vibrations when walking. There are also known devices that can display the amount of calories consumed. Cases that make this kind of pedometer portable include:
Generally, as shown in Fig. 5, there is a main body 1 in which a counter for counting and displaying the number of steps, a display device for displaying the number of steps, a reset switch, etc. are incorporated, a leaf spring attached to the back side of the main body 1, and a synthetic resin. These elastic pieces 2 are configured to elastically pinch four items to be held 3: a band, an opening edge of a bogget, and a jacket.

[What the invention is trying to solve! ! ! ]however,
In such a conventional pedometer, the object 3 is simply held between the main body 1 and the elastic piece 2, so the elastic piece 2 opens when subjected to a large external force due to walking posture, mounting position, etc. There was a problem that the pedometer would come off the band 3 and fall off.Therefore, it would be possible to prevent the pedometer from falling off by increasing the spring force of the elastic piece 2, but in that case, it would be difficult to attach it to the object to be held 3. Become.

Therefore, the present invention has been made in view of the conventional problems as described above, and provides a portable meter that has a simple structure and can reliably prevent the pedometer from falling off from an object to be held, such as a band. The purpose is to provide a case.

[! [Means for Solving the Problems] In order to achieve the above object, the present invention includes a main body, and the upper end of the main body is supported by a shaft so as to be freely openable and closable, and the main body is covered with a band or the like. a plate-shaped clip for clamping an object; a protrusion integrally protrudes rearward near a rotational fulcrum of the clip on the back surface of the main body; By forming a pair of left and right cut grooves, a tongue-like elastic piece is provided corresponding to the protrusion, and an engaging claw is provided at the lower end of the clip,
The protrusion presses the elastic piece rearward to elastically deform the object when the object is being held, and the engaging claw is positioned directly below the main body when the object is being held.

[Operation 1] In the present invention, when the clip is closed and an object to be clamped, such as a band, is clamped between the main body and the clip, the protrusion comes into contact with the inner surface of the tip sag of the elastic piece and elastically deforms it rearward. The reaction force acts as a biasing force that biases the clip toward the main body. When the clip is closed, the engaging claws are positioned directly below the main body, and together with the lower surface thereof, clamp the object.

[Example] The following five embodiments of the present invention will be described in detail based on examples shown in the drawings.

FIG. 1 is an external perspective view showing an embodiment of the portable instrument case according to the present invention applied to a pedometer case, FIG. 2 is an enlarged cross-sectional view taken along the IN-U line in FIG. 3, and FIG. 4 is a front view of the pedometer, and FIG. 4 is a partially cutaway blue surface of the pedometer. In these figures, the pedometer, which is generally designated by the reference numeral 10, includes a main body 1 that counts and displays the number of steps taken, and a plate that is disposed on the back side of the main body 1 and that holds an object 3 such as a band between the main body 1 and the main body 1. A case is formed by these clips 2.

The main body l consists of an outer case 11 with an open back, and an inner case 1.
2 and a back cover 13 in a thin box shape, and inside the inner case 12 there is a well-known pedometer (not shown) that counts the number of steps, and a display section W14 such as a liquid crystal display that displays the number of steps.
A reset switch 15 is incorporated. The inner case 12 is housed in the outer case 11, and the display section of the display device 14 is provided on the back surface thereof, that is, on the surface that covers the back opening of the outer case 11. Said outer case 1
1 and the back cover 13 are connected at their lower ends by a shaft 16 so as to be relatively freely PW4 in the front-rear direction. Further, an engaging portion 1 is provided upwardly in the center of the upper end surface of the back case 13.
7 is integrally provided in a protruding manner, and the outer case 1 is attached to this engaging portion 17.
an elastic engagement piece 18 extending rearward on the upper end surface of 1;
By engaging, the rear opening of the outer case 11 is normally closed. Furthermore, a horizontal shaft 19 is disposed at the upper end of the back surface of the back cover 13, with its central portion held by a bearing g20, and the bearing portion 20 has a protrusion 21 having an appropriate length at the rear. It is integrally protruded towards the front. The tip surface of the protrusion 21 has a stepped surface 22, thereby forming a small protrusion 2 in which the upper half protrudes rearward from the upper half.
3 is formed.

The clip 2 is formed of resin into a flat plate shape having an appropriate thickness and width, and is provided on the rear cover 13 via the shaft 19 so as to be openable and closable in the front and back direction, and the clip 2 is provided on both sides of the upper end facing inwardly. Wheel bearing portions 24A and 24B are provided integrally projecting toward both sides, respectively, and each end of the shaft 19 is inserted into an insertion hole provided in these bearing portions 24A and 24B. The center part of the upper part of clip 2 is.

A pair of left and right notch grooves 25A and 25B are formed halfway in the height direction of the clip 2, thereby forming a tongue-shaped elastic piece 26, which is connected to the protrusion ag21.
It is set up correspondingly. The elastic piece 26 does not come into contact with the protrusion 21 when the clip 2 is opened upward as shown in FIG. When it contacts and is elastically deformed rearward and becomes approximately vertical, it overcomes the small protrusion 23 and the second
As shown in the figure, it abuts and locks on the stepped surface 22. Even in this state, the elastic piece 26 is kept elastically deformed rearward by the protrusion 23.

The lower end of the clip 2 extends downward by an appropriate dimension than the lower surface of the main body 1, and the lower end has an engagement member at the center of the inner surface that engages with the lower surface of the main body 1 when the clip 2 is closed. A claw 27 is integrally provided in a protruding manner.

In such a configuration, when attaching to the object to be held 3, the open clip 2 is closed and the object to be held 3 is sandwiched between the clip 2 and the back cover 13. At this time, the back cover 13 is attached to the outer case 11. If the clamped object e13 is a belt, which should preferably be closed, the body 1 should be held approximately horizontally, the clip 2 should be vertical, and the clip 2 should be inserted between the belt and pants (or skirt). All you have to do is close the main body 1 and bring the back of the back cover 13 into close contact with the surface of the belt.If you gradually close the clip 2 or close the main body 1 to the clip 2, the elastic piece 26 will close as described above. When the inner surface of the tip abuts and engages with the tip surface of the protrusion 21 and elastically deforms backward, the small protrusion 2
3 and abuts and engages with the step surface 22 of the protrusion 21. In this state, the elastic piece 26 is elastically deformed rearward, and its reaction force urges the clip 2 forward, thereby providing a force for clamping the object 3 to be clamped. When the clip 2 is closed, the protruding engaging claw 27 on the inner surface of the lower end of the clip 2 abuts against or closely faces the lower surface of the main body 1, as shown in FIG. Prevents object 3 from coming out upwards.

When an external force is applied to the clip 2 in this attached and used state, the tip of the elastic piece 26 protrudes! 21
Since the elastic piece 26 gradually rides on the small protrusion 23, the amount of rearward elastic deformation of the elastic piece 26 increases, increasing the clamping force.

Therefore, falling off from the object to be held 3 can be prevented. The amount of elastic deformation when in contact with the small shank aK23 is
It remains approximately constant until the elastic piece 26 opens by a certain angle or more and the state of abutting engagement with the small protrusion 23 is released.

If you want to know the number of steps you have taken while wearing it or reset it, push the elastic engagement piece 18 upward with your nail to disengage the elastic engagement piece 18 from the engagement t$17, and then If the outer case 11 is moved downward until it becomes approximately horizontal as shown in FIG. 1, and the back of the inner case 12 is turned upward, the display section of the display device 14 will be turned upward, allowing you to check and reset the number of steps. Easy to operate.

When removing the pedometer 10 from the object to be held 3, hold the main body 1 in your hand and move it upwards about the axis 19 until it becomes approximately horizontal to check the state in which the object to be held 3 is held between the clip 2 and the main body 1. Then, remove the pedometer 10 upward or push the elastic engagement piece 18 upward with your nail to disengage the elastic engagement piece 18 and the engagement part 17, and then remove the outer case 11. As shown by the two-dot chain line in FIG. 2, the pedometer 10 should be opened downward until it becomes substantially vertical, and then the pedometer 10 should be lifted upward.

In this case, when the outer case 11 is opened downward to a certain angle,
Since the lower surface of the outer case 11 abuts against and presses the engaging claw 27 of the clip 2, the clip 2 is moved rearward about the shaft 19 and the object 3 to be held between the rear cover 13 and the clip 2 is moved backward. Release the pinched state.

In addition, although the above-mentioned fiber example was explained in the case where the main body 1 was composed of three members: the outer case 11, the inner case 12, and the back cover 13, the present invention is not limited to this, and the inner case 12 is It may be something you don't have.

In that case, if a display device is provided on the front side of the outer case 11, the outer case 11 and the back cover 13 can be moved upward until they become substantially horizontal, making it easier to check the number of steps and perform a reset operation. Furthermore, you can remove the pedometer from the belt by lifting it up.

Furthermore, although the present invention has been described with respect to the pedometer 10 that does not include the calorie consumption display mwg,
It can also be applied to a calorie meter that only displays the amount of calories consumed by walking.

[Effects of the Invention] As explained above, the portable instrument case according to the present invention has the following advantages:
A tongue-like elastic piece and an engaging claw are provided on a plate-shaped clip that can be opened and closed on the main body, and when the clip is closed, the elastic piece is elastically deformed backward by a projection protruding from the front of the main body,
The reaction force urges the clip forward and the engaging claw is positioned to extend below the main body.
The object to be held can be securely held, and the pedometer can be prevented from falling off from the object.
