Description

A WARNING DEVICE TO PREVENT FRO HAVING A CAMELBACK One would have a camelback as a result of always taking a wrong sitting posture or a wrong standing posture for a considerable long time. Once a camelback is resulted, it would be very difficult for a person to restore the normal posture; it is particularly true to a growing child; therefore, the parents must pay close attention to the sitting and standing postures of their children.

In view of the incorrect sitting or standing posture to result in a camelback, a person has to pay close attention to his (or her) posture; however, people often overlook their sitting or standing posture; especially, the children usually do not know how to maintain a correct sitting and standing postures; in case of theier parents not reminding them, a camelback would be resulted. So far, there is no any camelback-preventing device available in the market, aside from having a long-time warning device to prevent one from having a camelback.

This invention provides a warning device to prevent a person from having a camelback. The present invention mainly comprises a left and right movable plates, being assembled together in a superimposed manner. The two movable plates are normally maintained in a superimposed manner by means of two springs. The right movable plate is mounted with a circuit board which is installed with a buzzer, two mercury batteries, and a plate spring with a clamp piece on the front end thereof. The left movable plate has a lug. Beside the lug, there is an insulating piece, being extended between the clamp piece and a conductive surface of the circuit board, whereby the buzzer is remained in turned-off condition.Whenever the left and right movable plates are pulled apart, the insulating piece will be moved from the position between the clamp piece and the conductive surface; sumultaneously, the buzzer will be truned on to send out a sound signal.

After the aforesaid device being assembled with two elastic belts and two carrying belts, the whole device can be used as a warning device to remind a user not to make a camelback un-intentionally.

Referring to Figs. 1 and 2, there shows an embodiment of the present invention, which mainly comprises a left movable plate 1, a right movable plate 2 and a top lid 3. One end of the left movable plate is furnished with an end slot 11 for fastening an elastic belt. The other end of the left movable plate is furnished with a U-shaped opening 12; a slot 13 is furnished in the middle part of the left movable plate. Both sides of the left movable plate are provided with two hooks 14 respectively. One side of the left movable plate has a lug 15, and both sides of the left movable plate are furnished with two flanges 16 respectively perpendicular to the plate 1.

One end of the right movable plate 2 has an end slot 21; both sides of the plate 2 have vertical edges 22 respectively. Each of the vertical edges 22 is furnished with a flange 23 perpendicular to the vertical edge. The left movable plate 1 is mounted above and superimposed on the right movable plate, being moved back and forth horizontally along and within the flanges 23 of the right movable plate 2. The mid point of the front end of the right movable plate 2 is furnished with a salient block 24, while both sides of the rear end of the plate 2 are furnished with two hooks 25 respectively. Both ends of the vertical edges 22 have two holes 26 respectively.

In order to maintain the two movable plates 1 and 2 being coincided each other, two springs 4 are used by mounting two ends of the springs 4 to two hooks 14 of the left movable plate 1 and two other ends thereof to two hooks 25 of the right movable plate 2. In order to prevent the left movable plate 1 from moving too far in right direction by the springs, the salient block 24 is mounted in the slot 13 for limiting the movement of the left movable plate.

A small circuit board 5 is fixed to the rear part of the right movable plate 2 by means of a two-side adhesive piece 6. The circuit board 6 has two contact points 51 and 52 for mounting two mercury batteries ; respectively; the two batteries are fixedly mounted in place with two fastening caps 71 respectively.

A plate spring S with a groove 81 and a clamp piece 82 is mounted on the spring piece 53 of the circuit board 5, and is soldered to the wires of the batteries.

The clamp piece 82 of the plate spring is closely contacted with the conductive surface 54 of the circuit board. The conductive surface is electrically connected with an IC 55.

A buzzer 9 is fixed to the circuit board, and is electrically connected with the IC 55 by means of two wires.

When the clamp piece 82 of the plate spring 8 is in contact with the conductive surface 54, the current of batteries 7 will flow, through the plate spring, and the conductive surface, to the IC, where an interrupting current will be generated, and transmitted to the buzzer to generate a sound signal.

The left movable plate 1 is mounted with an insulating piece 10, which is attached, with an adhesive pad 101, to the surface of the plate 1 behind the lug 13.

The insulating piece 10 is mounted between the clamp piece 82 and the conductive surface 54 to cause the circuit to be in an open condition; the buzzer would not generate any sound signal (as shown in Fig. 6). The lug 15 is used for stopping the circuit board, being the same as that of the salient block 24, i.e., to prevent the left movable plate I from being pulled by the springs too far to the right.

When the aforesaid parts are assembled together, it will be formed into a device as shown in Fig. 2; then, the top lid 3 is mounted over the right movable plate 2 by mating the beads 32 on the side walls 31 of the top lid with the correcponding holes 26 on the vertical edge of the right movable plate 2, and then the device will be covered closely.

Referring to Fig. 3, there show the end slots 11 and 21 on the ends of the left and right movable plates 1 and 2 being mounted with elastic belts 111 and 211 respectively.

Two ends of the elastic belts are connected with belts 112 and 212 respectively. Both ends of each belt are attached with Velcro tapes 113 and 213 so as to mount the warning device on one's back between two shoulders as shown in Fig. 4, in which the user's back carries the warning device in a correct and erect posture; both the belts and the device are maintained in normal manner; in other words, the user has to adjust the length of the elastic belts 111 and 211 in accordance with the width of his (or her) back before mounting the device on the back.

Fig. 5 illustrates a user having his back bent to an extent to cause the belts to be pulled forwards; in that case, the elastic belts will be pulled to cause the left and right movable plates 1 and 2 to be pulled; as a result, the buzzer 9 will generate a sound signal to the user that a correct body posture is required; otherwise, the buzzer will send out sound signal continuously.

Fig. 6 illustrates the left and right movable plates of the warning device of the present invention not being pulled in the opposite direction; the insulating piece 10 is set between the clamp piece 82 and the conductive surface 54. Since the clamp piece 82 is unable to contact with the conductive surface- 54, the whole circuit of the present invention is set in an open circuit condition; therefore, the buzzer would not send out any sound singal.

Whenever the left and right movable plates are pulled in the opposite direction as shown in Fig. 7, the insulating piece 10 will be pulled out of the position between the clamp piece 82 and the conductive surface 54 to have the clamp piece 82 directly contacted with the conductive surface 54; in that case, the whole circuit is turned on; the buzzer 9 will send out a sound signal immediately to remind the user to restore to a normal posture.

If the user has corrected his (or her) posture, the left and right movable plates 1 and 2 will be pulled, by the two springs 4, back to their original position as assembled.

If the user did not restore his (or her) posture to the normal position, the buzzer will send out a sound signal continuously; in that case, the user can not but restore his (or her) back to a normal posture.

It is apparent that the present invention can remind a person who wears the same not to bend his (or her) backbone. Since the present invention is light and small in size, any one can wear it under one's coat or jacket without being seen by others. One can wear it comfortably for a very long time
