Abstract
Description
- In the orthopaedic field, the medical science studies and suggests, in the different cases, aids concerning disabled persons or traumatized persons.
- One of the above-mentioned aids concerns the invalid chairs or seatings. The seatings available on market are of innumerable types and purposes. There are fixed and tracked seats, standardized and personalized seats. The seats achieved by the various manufacturers according to doctors', therapists' and orthopedists' suggestions, are conceived to reach the highest benefit in compliance with patients' requirements.
- The multiplicity and variety of cases concerning the skeletal and anatomic imperfections have led the seat manufacturers to achieve backrests divided into several parts, allowing suitable and proper adjusting, in consideration also of the build and of the age of patient; this can be a young person, and therefore on growing age, or an adult person.
- The seating of the present patent features a backrest quite different from any other backrest existing on market, and capable of satisfying the various requirements which should arise.
- Said backrest, such as considered as an example in the present patent, is practically made up of four quadrants, independent between them and each capable of being adjusted on an independent and diversified manner compared to the others.
- When a patient, having specific skeletal anomalies in his anatomical structure is placed on seat, the single parts which compose the backrest are adjusted one by one. If with the time, for the same patient, some changes occurr, including the growth variations if the patient is on growing age, you may periodically conform the positioning of the above said parts which compose the backrest by means of adjustments.
- It is understood that the seating, made up by the seat and the backrest above described is equipped, on the various surfaces which come to contact with the person placed on it, with suitable padded cushions.
- Said cushions can be on their turn applied on the bearing surfaces of the seat by means of "Velcro" straps coupling method, which allows its easy removal, replacement and re-positioning.
- The seating bearing frame, without seat and backrest, is schematically composed by two tubular elements, which after the first upper horizontal section, which form the handgrips, go down almost vertically by the length representing the backrest extension and will afterwards shape almost horizontally forwards by thel ength corresponding to seat extension.
- The two elements are kepts spaced by means of cross connections by the required extension to house a seat and a backrest.
- The seat and the backrest generally have their own frame, bolted on two opposed sides, on brackets with a plurality of holes. Said brackets are equipped on one end with a semicircular coupling, whose opening corresponds to the diameter of the tubular elements of the seating bearing frame, where these couplings are to be fitted.
- The seat and backrest, placed ont the seating bearing frame, are hold back by special clamps equipped with extensions which are to be be fitted on the semicircular couplings of the brackets, of which seat and backrest are provided.
- In the specific case of the seating of the patent, the frame of the backrest is achieved by two curved crosspieces arranged almost horizontally, bolted on ends, with brackets having several holes. Said brackets are equipped on one end with semicircular couplings, whose opening corresponds to the diameter of the tubular element of the bearing frame of the seat, on which said couplings are to be placed.
- Said two crosspieces with their brackets are kept spaced by means of two flat elements with almost vertical arrangement, having several holes.
- Said flat elements with their holes plurality allow to modify, when required, the distance from each other of the crosspieces from the backrest frame.
- The single parts which compose the resting surface of the backrest are supported in the middle of the back side, by a spindle which makes up on one end a ball joint coupling with them. The other end of the spindle opposed to the ball joint is engaged in the hole of a block, where it can slide and turn. Said block is provided of a second hole , whose axle is suitably off-centre compared to the axle of the first hole, and makes up with this axle an approximately 90 degrees angle.
- Said block is engaged with said second hole, off-centre, in one position of one of the curved crosspieces, along which it can slide and turn.
- After the adjustment is completed, the block is made integral to the crosspiece which supports it and the spindle with ball joint, supporting one of the parts which represent the backrest support, is made integral to the block.
- The adjustment is completed by operating on the screws which block the movements of the ball joint. As previously said, each single part which form the resting surface of the backrest is capable of being adjusted independently from the others, this being the main characteristic of the patent.
- The seating considered up to now can refer to that of a wheelchair or to that which can be placed inside a car for a disabled persons enabled to drive, and still to any other case or event which may actually occur.
- What said above can be better clarified through the examination of the enclosed drawings.
- Fig. 1 shows schematically one of the two elements of a seating frame, where the seat and the backrest are housed (these latter are not pictured here).
- It can be noticed the
handgrip 1, thevertical section 2 and thehorizontal section 3. There are not pictured the cross elements which keep the above lateral elements spaced. - The
devices extensions - Fig. 2 corresponds to Fig. 1, where the seating frame is completed by the implementation of a
generical seat 6 and agenerical backrest 7. - Both
seat 6 andbackrest 7 are equipped on two opposed sides withbrackets 8 which are equipped on their end with semicircular couplings, which surround thetubular elements - In the picture there are drawn in broken line the possible orientations which can be taken by
seat 6 andbackrest 7, by properly fixing them tobrackets 8, by means of the several holes which are arranged on saidbrackets 8. - The
extensions clamps seat 6 andbackrest 7 - Fig. 3 shows the backrest executed according to patent, alone, not fitted in the seat.
- It can be noticed the bearing frame composed by two
curved crosspieces brackets 8. Saidbrackets 8 are equipped on one end with semicircular couplings, whose opening corresponds to the diameter of thetubular element 2 of the bearing frame of the seating. Said twocrosspieces brackets 8 are kept spaced by twoflat elements 15 with almost vertical arrangement. Said verticalflat elements 15 which are equipped with a plurality of holes, allow to change, when required the distance from each other ofcrosspieces - On
crosspieces blocks 16 with holes, which surround the branches of said crosspieces. - Said
blocks 16 can slide along crosspieces and rotate around them. - Each
block 16 is equipped with a second hole, whose axle compared to the axle of the hole which surrounds the crosspiece, ensues to be off-centre and forming an angle corresponding approximately to 90 degrees. This second hole represents the seat in which aspindle 17 is placed, equipped on one end with aspherical head 20. Saidspindle 17 which can slide and rotate in the seat where it is housed, is meant to support by means ofspherical coupling 18 one ofparts - Once the adjustment is completed, the
block 16 is made integral to itscorresponding crosspiece spindle 17 withball joint parts ball joint single parts - Fig. 4 shows an exploded view of the various parts, that is, the
bar block 16, thespindle 17, theball joint resting elements - Fig. 5a shows the
block 16 viewed alone; Fig. 5b shows the assembling ofblock 16 withspindle 17 and theball joint 18. Fig. 5c corresponds to Fig. 5b, viewed from another angle. - Fig. 6 shows four different orientations of the
ball joint 18, concerning the same parted representation of acrosspiece section spindle 17 bymeans block 16. - Fig. 7 shows the upper part of a seat concerning the backrest executed according to patent, where the structure of the frame is viewed from front side, being the single
