Abstract
The chiropractic device includes an elongated flat base, and a front stopping block and a back stropping block at the base's two ends. The front and back stopping blocks have a semi-circular cylindrical shape, with 45-degree slant support face on one end and a vertical face on the other end. Between the front and back stopping blocks, there are a main block and a number of stopping plates of different lengths. Along a top edge of the front and back stopping blocks, the main block, and the stopping plates, an end-to-end trough is provided. The chiropractic device is able to adapt its length so that users of different heights may lie on the chiropractic device for spinal relaxation and correction to the spine.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
(10) The following descriptions are exemplary embodiments only, and are not intended to limit the scope, applicability or configuration of the invention in any way. Rather, the following description provides a convenient illustration for implementing exemplary embodiments of the invention. Various changes to the described embodiments may be made in the function and arrangement of the elements described without departing from the scope of the invention as set forth in the appended claims.
(11) The present invention provides a chiropractic device assisting spine correction without applying external forces. As shown in FIGS. 1 to 9, the chiropractic device according to an embodiment of the present invention includes an elongated and flat base 10. An upward protruding front stopping block 11 is disposed at a front section on a top side of the base 10. The front stopping block 11 has a slant front support face 12 at a front end. The front support face 12 has a 45-degree included angle with the base 10 and a front edge aligned with that of the base 10. The front stopping block 11 has a semi-circular flat face (not numbered) at a back end perpendicular to the base 10. The front stopping block 11 overall has a roughly semi-circular cylindrical shape. The radius of the flat face generally is 7.5 cm for better ergonomics. It may vary between 7.5 cm and 10 cm depending on the height of a user. The overall height of the front stopping block 11 together with the base 10 is preferably between 10.5 cm and 13 cm so as to conveniently raise a user's back and to achieve appropriate chest expansion. The base 10 has a length generally between 70 cm and 80 cm to fit users of different heights. The front stopping block 11 has a trough 13 extended along a top edge from the front support face 12 to the flat face. The trough 13 has a U-like cross section. There are two walls 14 arranged in parallel along two main edges of the top side of the base 10, respectively. Therefore a track-like indentation is formed between the walls 14 for the placement and positioning of components such as a main block 20, stopping plates 21, a back stopping block 22, etc. in between. The main block 20 has a semi-circular cylindrical shape with front and back flat faces perpendicular to the base 10. A front flat face is attached to the front stopping block 11. The man block 20 has a length between 30 cm to 32 cm and functions as the main support and correction part for spine. There are a number of stopping plates 21 of an identical cross-sectional shape to that of the main block 20 but of different lengths. The stopping plates 21 have lengths between 2 cm to 5 cm so that they are not too thin and deformed easily. Depending on a user's height and his/her spine length, stopping plates 21 of different lengths are selected and positioned sequentially within the indentation. The back stopping block 22 is structured symmetrically to the front stopping block 11 and is disposed at a back section on the top side of the base 10. The back stopping block 22 therefore also has a slant back support face 221 so that the chiropractic device of the present embodiment has slant front and back support faces 12 and 221 at the front and back ends, respectively. The main block 20, the stopping plates 21, and the back stopping block 22 all have end-to-end troughs 23 and 231 along their top edges. The troughs 13, 23, 231 are aligned and have identical cross-sectional shape so that they jointly form a single trough extended from one end of the chiropractic device to the other end. The front and back stopping blocks 11 and 22, the main block 20, and the stopping plates 21 are made of a relative hard yet flexible rubber of plastic material such as Ethylene-vinyl acetate (EVA), Polyurethane (PU) so that they will not be deformed under a user's weight but also provide comfortable contact. The hardness is between 60 and 80 Shore hardness. Alternatively, the front and back stopping blocks 11 and 22, the main block 20, and the stopping plates 21 may be covered with a soft flexible pad layer. In addition, the trough 23 of the main block 22 may be configured with a number of accommodation seats 24 at intervals where magnetic elements 25 are disposed so as to further provide rehabilitation effect. The accommodation seats 24 are of an appropriate depth so that the magnetic elements 25 do not bulge beyond the trough 23's top side so that they will not contact a user's back to cause any uncomfortable feeling.
(12) To use the present embodiment, the present embodiment is placed on an elongated flat surface such as on a rehabilitation bed. An appropriate number of stopping plates 21 are assembled so that the present embodiment has an appropriate length according to the length of a user's upper torso. The user then directly lies on the present embodiment so that the present embodiment is right beneath the user's spine. As shown in FIGS. 5 to 7, the user's neck and head is supported by the front support face 12 of the front stopping block 11, and the head is pulled by gravity of its own weight. The head should not touch the elongated flat surface. On the other hand, the user's hip is supported by the back support face 221 of the back stopping block 22, and the hip's own weight provides a downward pull. As such, through the weights of the head and the hip, the user's spine is naturally pulled and stretched, thereby achieving rehabilitation and correction. In the meantime, the semi-circular main block 20 and stopping plates 21 slightly raise the user's upper torso and outward expand the user's chest as shown in FIG. 7, thereby achieving correction and restoration to the spines of patients with scoliosis. The aligned and cascaded troughs 23 and 231 accommodate the spine, especially the bony spurs, without causing pain or uncomfortable feeling of oppression. By constantly lying on the present embodiment, a normal person can conveniently prevent spinal deformation or damage, and achieve correction and care by himself/herself.
(13) The greatest features of the present embodiment are as follows. The length of the present embodiment is adaptable to fit different users. The height of the present embodiment and the significantly slant support faces 12 and 221 provide pull to the two ends of a user's spine by the user's own weight. Without the application of external force, as common in the prior art, harm to the user may be prevented. The user can also vary his/her posture to adjust the pull. The height of the present embodiment is between 10.5 cm and 13 cm, and the user's upper torso is slightly raised. Therefore, if the user feels too strong a pull, he/she can easily turn the body slightly or use the elbow to press against the elongated flat surface to quickly lessen the pull for enhanced usage safety.
(14) The main block 20 of the present embodiment may be used independently as shown in FIGS. 8 and 9. As illustrated, the main block 20 is placed on the elongated surface alone, perpendicular to the body's axis and underneath the neck or waist. The main block 20's semi-circular cylindrical shape and appropriate height provides comfortable support to the neck or waist. The main block 20 may also appropriately expand and relax the cervical vertebra. The length of the main block 20 also allows the user to turn over without falling off. The main block 20 therefore may function as a rehabilitation pillow, providing appropriate correction and rehabilitation to the waist and neck.
(15) While certain novel features of this invention have been shown and described and are pointed out in the annexed claim, it is not intended to be limited to the details above, since it will be understood that various omissions, modifications, substitutions and changes in the forms and details of the device illustrated and in its operation can be made by those skilled in the art without departing in any way from the claims of the present invention.
