Description
Apparatus for indicating correct or faulty back posture s The present invention relates to a device for placing on a person's head to indicate correct or incorrect upright posture during the performance of various activities in a standing or sitting position, comprising a balance element connected to a headband, a hairband, an ear clip or other appropriate means for attachment to a person's head.
~o A device of this kind is taught in the applicant's own Norwegian Patent 1X,349. This device consists of a balance body which is attached to a U-shaped band, which in turn is attached to a hairband or similar. A spring or similar is located between the legs of the U-band so that the balance body will tip forward when the head is moved too far forward and out of a correct head position. When this happens, a signal will be given to ~s indicate that the user has assumed an incorrect sitting posture.
This device functions extremely well under qualified guidance, but nevertheless encumbered with certain weaknesses. For example, the device is rather large anu lumpy and projects quite high above the user's head. This means that the device could easily zo be torn off the head if the user knocks into a low door frame or similar.
Further, the device has proven to be somewhat diffcult to calibrate and is very sensitive to deviations from the correct calibration. Moreover, it is difficult for the user to perceive when the balance body of the device tips forward, and he or she is therefore zs dependent on either a mirror or having another person present as an observer.
Moreover, the device will only indicate incorrect head position when the head is tipped too far forward. It will not indicate an incorrect head position when the head ~s tipped sideways.
According to an aspect of the present invention there is provided a device for placement on a person's head to indicate the person's correct or incorrect upright posture during performance of activities in a standing or sitting position, the device comprising an inclination indicator, the inclination indicator being connected to an attachment means la for attachment to the person's head, wherein the inclination indicator includes a fixed body which is fixedly mounted on the attachment means and an indicator body moveable on a surface substantially coincident with a horizontal plane from a start position when a certain degree of deviation of the head from the correct position occurs, in a plurality of directions relative to the fixed body, and wherein the indicator body returns to the start position when the correct head position is once more assumed, and the device further comprising a signalling means associated with the fixed body, whereby the signalling means is activated by the indicator body to give an audible signal in response to movement of the indicator body in each of at least two of the plurality of directions.
In order to eliminate these disadvantages it is therefore proposed to design the device as described in more detail below with reference to the accompanying drawings, wherein:
WO96107454 ''. , y' PCTlN095100150 ~ ~ ~~~ci;~
Figure 1 illustrates a device where the moveable body is a slide which can move in a channel in the fixed body.
Figure 2 shaves a device where the moveable body is a pin which, when the head s position is incorrect, will move out of a recess in the .fixed body.
Figures 3a and 3b show the movement of the moveable body according to Figure 2.
Figure 4 illustrates a device where the moveable body is a ball which will call slang an ~o inclined plane when tire head position is incorrect.
Figure S shows a section through the device in Figure 4 along the line V-V.
Figures 6 - 9 show a moveable body made of a disc which is designed to mane in a hale ~s in the fixed body:
Figure 6 shows the device from above and with the moveable body in a neutral position;
Figure 7 shou~s a section along the line VIl-VII in Figure 6;
Figure 8 shows the device from above with the moveable body displaced fiom the neutral position;
Figure 9 shows a section along the line IX-I~ in Figure 8.
zs In Figure 1, a device 1 is shown placed on a person's head 2. with the aid of an attachment means 3, which may be a hairband, a headband or another appropriate means. The device 1 consists of a fixed body 4, which is firmly secured to the attachment means 3, and a moveable body 5, which can move translationally relative to ao the fixed body 4.
In the exemplary embodiment according to Figure I, the moveable body 5 consists of a slide block Sa which is designed to move in a channel 6 in the fixed body 4.
When the position of the head is correct, the block Sa will preferably be at the highest point of the ~s head and preferably in the rear end of the channel 6. if the head is bent toe far forward, the weight of the block Sa will overcome the frictional forces against the channel 6 and the block Sa will move forward in the channel 6. The materials and design of the block WO 961x7454 " ~ , H
J rc~rn~oys~oatsa Sa and the fixed body can be chosen so that an audible sound is made when the block Sa strikes the end of the channel 6.
In Figure 2, a second embodiment of the device is show. Here, the moveable body 5 s consists of a pin Sb and the fixed body consists of a holder 4b equipped with a through-going slot 7 which defines a place 8 having a recess 9 at the rear end thereof. 4t'hen the position of the head is correct, the pin Sb is in the recess 9, but when the head is tipped too far forward, it will roll out of the recess 9 and down the plane 8 and preferably make an audible sound when it strikes against the end of the holder 4b. Figures 3a and 36 ~o show the position of the pin Sb when the position of the head is correct and incorrect, respectively.
An embodiment is shown in Figure 4 where the moveable body consists of a ball Se and the fixed body of a box 4c. The box 4c is equipped with an inclined plane 10 which is is preferably curved in such a way that it inclines from the edges of the box and down towards a bottom point 11 at the back edge 12 of the box. In the neutral position, the ball Sc will be at the lowest point 11 of the inclined plane. When the head is tipped too far forward or perhaps to the side, the inclined plane will move past the horizontal position and the lowest point 11 will thereby come to be higher than the inclined plane zo at the ~posite end thereof. The ball will thus roll down the inclined plane and strike against the box wall, preferably making an audible sound in doing so. The box 4c is preferably closed so that the ball 5c is prevented from falling out. The box 4c is attached in an appropriate manner to a headband or similar.
as Figures 6 - 9 show a fourth embodiment where the moveable body consists of a disc Sd and the fixed body consists similarly of a disc 4d of greater diameter. As can best be seen in Figure 7, the disc 4d is double and in one wall bas a hole 13 of a smaller diameter than the diameter of the disc Sd. Said disc Sd is also double, but the walls in this case are only connected in the centre of the disc. The disc Sd is placed in the hole ao 13 so that one of the walls 14 of the disc Sd is on the inside of the edge of the hole, whilst the other wall 15 is on the outside. When the position of the head is correct, the disc Sd is centred in the hole 13. On deviation from the correct head position, the disc Sd will shift relative to the hole 13 and clearly indicate that the head position is incorrect. Also in this case, an audible sound will preferably be made when the disc Sd ss reaches its outermost position. Both the disc Sd and the disc 4d are preferably double curved, so that the device is less sensitive to movement. The curve can be varied according to the desired degree of sensitivity.
W 0 96107454 .~ PCTlN09SllN1 t S0 ~' ~ ~f3~C~~a In an embodiment that is nut illustrated, the moveable body may consist of a mercury ball or similar which on deviation from the correct head position moves in such a way that it closes an electronic circuit. The electronic circuit may be formed so that it emits s an audible sound, e.g., a piping sound, actuates a vibration device, gives a light signal or in another mannor indicates that an incorrect head position has been assumed.
The device may also be equipped with a proximity sensor which detects the position of the moveable body and gives a continuous or stepwise signal dependent on the position.
