BRIEF SUMMARY
BACKGROUND OF THE INVENTION
The present invention relates to an apparatus to be placed on the head of a person to indicate correct or faulty back posture during execution of various activities in an upright or sitting position.
The apparatus can thus be utilized in daily life at various work places and during the execution of different leisure time activities such as exercizing, gymnastics, aerobics, jogging and ballet.
In connection with back ailments, it has been recommended by a number of doctors, physical therapists and others that the spine should be held as straight as possible during various activities associated with both work and leisure. This applies, for example, to bending, sitting on an office chair, and to lifting.
We do not know, however, of any suitable mechanical aid for holding the back in the correct position during execution of the quite numerous daily activities that produce strain on the spinal column.
SUMMARY OF THE INVENTION
The purpose of the present invention is to provide an apparatus which, when used, will help a person hold the spinal column straight when the person sits on an office chair, has to lift something or bend over, etc.
This is achieved according to the invention by means of the characteristic features disclosed in the characterizing clause of the following independent claim 1 and in the subsequent dependent claims.
Experiments conducted using the apparatus in accordance with the invention have shown that the user's back is held straight and the back posture is correct even during prolonged periods of work with, for example, house cleaning or typing.
The balance member preferably consists of a plate member connected for springing movement with and unstably supported by a base section attached to a hair band, which may be placed on a person's head. At each end of the plate member is attached a weight element, said weight elements causing a moving deflection of the springing, movable plate member when the user's head is moved, and resulting in a swinging motion toward one side or the other, or forward and backward, from an intermediate position which is to indicate correct back posture.
The actual plate member/balance plate may be made of plastic. By providing two parallel incisions in the midsection of the plate from one longitudinal edge toward the other longitudinal edge thereof, and by bending in the strip thus produced into an approximate U-shape under the plate, one forms a hinge strip, the free end of which may be attached to the above mentioned hair band. Depending on the resilient properties of the strip, in order to achieve a desired spring motion between the plate with the weights and the attachment point for the strip, a spring may be positioned between the point of attachment of the strip on the hair band and its origin in the plate member.
BRIEF DESCRIPTION OF THE DRAWINGS
An embodiment example in accordance with the invention will be described further in the following, with reference to the illustration, where
FIG. 1 in perspective shows the apparatus positioned on a hair band,
FIG. 2 shows the apparatus seen from the side with the hair band placed on a head,
FIG. 3 shows an alternative embodiment of the apparatus placed on an elastic forehead band, and
FIG. 4 shows the same as FIG. 2, but with the head bent to show the indicative deflection of the apparatus.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
The apparatus comprises a balance member 1 which is shown in FIG. 1 as an elongate plate member connected for springing movement with and unstably supported by a base section 2 attached to a hair band 3 that may be placed on a person's head, as is shown in FIGS. 2 and 4. The balance member 1 is, as shown in FIG. 1, connected with the base section 2 by means of a U-shaped flexible, springy band 4. This U-shaped band 4 may either be an integral part of the balance member 1, or may be attached thereto by one leg 4b thereof with the aid of screws, pins or glue, and may with its other leg 4c constitute base section 2 or be attached to a base sect
