Description

Orthopedic collapsible chair

Field ofthe Invention

This invention relates to an orthopedic collapsible chair, which in its folded state serves as an orthopedic chair with adjustable seat depth and also with adjustable inclination of the back-rest while the same equipment in its unfolded state serves as an orthopedic bed. Under the sitting part ofthe device there is a drawer fitted, which acts as storage space for bed-clothes.

Background to the Invention

The purpose of a collapsible chair or a collapsible couch is to achieve such an arrangement within the piece of furniture as to allow for the greatest saving of space. Such a device ought therefore to be entirely free in its movements on its own castors and should also be equipped with storage space for bedclothes. As well as the above requirement a collapsible chair or collapsible couch could provide comfort that is fully in compliance with health needs both for sitting and for lying and sleeping.

The technical solution of collapsible chairs or collapsible couches known in the art certainly allows for a certain saving of space, but the majority of them do not have their own supporting castors so that one cannot freely move them from one place to another in a room according to the actual requirements. Likewise the great majority of collapsible chairs or collapsible couches do not have their own storage space for bedclothes. The technical design of collapsible chairs or collapsible couches is also remarkable for what is as a rule a rather complex folding and unfolding mechanism (fittings) which also considerably increase the selling price of this kind of furniture.

None of the technical designs for collapsible chairs or collapsible couches up to date provides comfort that is fully in compliance with health requirements both for sitting and for lying and sleeping. This is caused by the fact that the technical designs currently used for this kind of furniture rely on the disassembly of the bed-mattress usually into at least three folding components, whereas a rational health-oriented approach requires that for high-quality support of the spine the bed-mattress should always be made up of one single unit. That apart, none of the technical designs for collapsible chairs or collapsible couches allows for the control of individual seat depth or the setting of back-rest inclination to fit the individual. Description ofthe Invention

The virtue of this technical solution lies in a collapsible chair with a storage space for bedclothes, which in its folded state may be used as an orthopedic chair, or as the case may be as an orthopedic couch with adjustable seat depth and adjustable inclination of the back-rest, and in its unfolded state it acts as an orthopedic bed for at least one person.

I.

The weight-bearing frame of this device, which is separable from the single-piece orthopedic lying and sitting section, is made up of a cabinet of drawers, the top surface of which is made of at least one single-piece weight-bearing horizontal board and also of at least one cabinet bed-clothes drawer, which is set sliding-fashion into the cabinet of drawers, and from the coupling of mutually rotating joined supporting boards, of which the front one is leaning in a folded state against the drawer cabinet and the back one is leaning in a folded state either against the drawer cabinet or against the upper side edge of the cabinet drawer, while in an unfolded state both supporting boards are together with the horizontal weight-bearing board set on the horizontal plane of the bed for placing the orthopedic grating or mattress.

One original and unique consequence of the coDapsible-chair weight-bearing frame construction described above is the option of placing upon it a separable single-piece orthopedic grating or a separable single-piece orthopedic mattress, without this preventing the unfolding or folding of this chair according to the momentary needs ofthe user.

As a result of the fact that the weight-bearing frame of the orthopedic collapsible chair is separable from the orthopedic lying and sitting portion, one has the option of fixing various kinds of special orthopedic mattresses to this supporting frame in accordance with the requirements ofthe user.

As a consequence of the fact that the lying and sitting portion of the collapsible chair that has been designed is made of a single piece, the condition is met whereby an orthopedic surface for lying should not be made up of several independent and separable areas, so that there should not be any undesirable sinking of the spine into the gaps between these separable areas. An example of a bed that does not comply with health requirements is one with a two-part or three-part mattress.

As a consequence of the fact that the basic component of the device is the cabinet of drawers, the top part of which is the horizontal weight-bearing board, the entire device is in the foπn of a cabinet, which allows one to sit on the horizontal weight-bearing board of this cabinet. As a result of the fact that inside the drawer cabinet a cabinet drawer is located, there is the option of using this drawer both in its folded state for storage of bed-clothes and also in its unfolded state, when at the upper edge ofthe slid-out walls of this drawer we can place another construction to ensure support for the back for sitting and lying.

As a consequence of the fact that inside the drawer cabinet there is at least one bed-clothes drawer that is slid into place, the dimensions of die entire device being at the discretion of the user, there is the option of creating a collapsible couch for two or more persons, who will each have the opportunity of storing their bed-clothes in their drawer.

As a consequence of the fact that the construction that provides support for sitting and lying is made of two mutually rotating connected supporting boards, there is the option, according to the actual need ofthe user, of either folding this construction into the shape of a canopy, placed on the weight-bearing frame of the orthopedic collapsible chair, which serves the function of support for sitting, or of unfolding it into a horizontal plane, parallel to the horizontal weight- bearing board, together with which it then performs the function of support for lying. As a consequence of the fact that a cabinet drawer, which forms the support for the placing of the supporting boards, is freely mobile within the drawer cabinet, there is the option, by setting the positions of the cabinet drawers and the supporting boards relative to one another, of controlling the angle of inclination ofthe back-support for sitting and there is also the option of increasing the seat depth by moving the supporting boards further back from the rear area of the horizontal weight-bearing board.

As a consequence ofthe fact that the horizontal weight-bearing board is made of no more than one piece, there is the option, by removing several pieces, of allowing for the movement ofthe supporting boards forward to the front area ofthe horizontal weight-bearing hoard and thereby shortening the seat depth in accordance with the momentary needs ofthe user. π.

On the weight-bearing horizontal board and also on both of the other supporting boards in a lengthwise direction there is affixed either the special orthopedic grating alone or the special orthopedic mattress alone or the special orthopedic grating, to the front part of which, designed for sitting, the special orthopedic mattress is affixed, or the orthopedic mattress with built-in special orthopedic grating.

The special orthopedic grating alone placed directly on the weight-bearing sitting board and on both of the supporting boards together with the weight-bearing frame of the orthopedic collapsible chair create one single functional unit. Moreover the special orthopedic mattress placed directly on the weight-bearing sitting board and then also on both supporting boards together with the weight-bearing frame of the orthopedic collapsible chair create one single functional unit.

Furthermore the special orthopedic mattress placed on the special orthopedic grating lying on the weight-bearing board and both supporting boards together with the weight-bearing frame of the orthopedic collapsible chair create one single functional unit.

The special orthopedic mattress placed on the special orthopedic grating may be connected up as a single unit not only in teπns of function but also in terms of form.

As a consequence ofthe fact that upon the weight-bearing frame ofthe collapsible chair there is placed directly either the special orthopedic grating or the special orthopedic mattress, the entire device has orthopedic qualities which give it a significant advantage over the other kinds of collapsible chair that have appeared to date.

III.

For the orthopedic collapsible chair to function correctly it is important that the drawer cabinet should have its front and two side walls raised against the horizontal weight-bearing board in the form of an enclosure.

As a consequence of the drawer cabinet having its front and two side walls raised against the horizontal weight-bearing board in the form of an enclosure, the constructional arrangement prevents the orthopedic grating or orthopedic mattress placed on the horizontal weight- supporting board from shpping to one side or moving forward.

It is preferable for the drawer cabinet of the orthopedic collapsible chair designed for the storage of bed-clothes to be fitted with castors on its bottom panel.

As a consequence of the drawer cabinet of the orthopedic collapsible chair being placed on castors, there is the option of easy movement of its construction about the room in accordance with the needs ofthe user at any moment.

It is useful for both the inner side boards of the bed-clothes cabinet to be fitted with weight- bearing bars with supporting holes for the side supporting projections of both supporting boards in order to set the position of these supporting boards.

As a consequence of the fact that on both the inner side boards of the bed-clothes cabinet, weight-bearing bars are fitted, there is the option of supporting at least one of the two movably connected supporting boards on these bars, thereby facilitating their sitting and lying function. As a consequence of the fact that ou the side weight-bearing bars, supporting holes have been bored for the supporting side-projections of both supportmg boards, there is the option of fitting the supporting boards placed upon these weight-bearing bars in the position required by the user.

It is also useful that beside the last supporting hole on at least one ofthe weight-bearing bars of the bed-clothes cabinet there should be a fitting aperture for inserting the fitting peg in order to fasten the bed-clothes drawer in the chosen position.

As a consequence of the fact that beside the last supporting hole on at least one of the weight- bearing bars of the bed-clothes cabinet there is a fitting aperture for inserting the fitting peg, there is the option by means of this peg of fastening the bed-clothes drawer in the chosen position in accordance with the requirements ofthe user. V.

For the coπect functioning ofthe orthopedic collapsible chair it is important that the outer front wall of the cabinet drawer should be raised above the horizontal level of both supporting boards.

As a consequence ofthe fact that the outer front wall ofthe cabinet drawer is raised above the horizontal level of both supporting boards, there is a design arrangement which prevents the movement backwards of the orthopedic grating, or the orthopedic mattress placed on the weight-bearing surface ofthe bed.

It is of benefit that the cabinet bed-clothes drawer should be equipped on its bottom wall with at least one roller.

As a consequence ofthe fact that the cabinet bed-clothes drawer is equipped on its bottom wall with at least one roller one can easily slide this drawer in and out and there is thus a considerable easing of use of this orthopedic collapsible chair.

It is also of benefit that the cabinet bed-clothes drawer should be equipped on the outer side of its side walls with furniture runners for the movement inside the drawer cabinet, the cabinet bed-clothes drawer is movable inside the drawer cabinet by means of conductive furniture runners, there is a considerable easing of the sliding out and sliding in of the drawer and thus ofthe handling ofthe entire orthopedic collapsible chair. VI.

In the top edge of both side boards of the cabinet drawer there are supporting holes for the supporting side projections of both supporting boards. As a consequence of the fact that in the top edge of both side boards of the cabinet drawer there are supporting holes bored at certain distances from one another, into which the side pegs or as the case may be the side rods are rested, one may fasten the supporting boards placed on the upper edge of the side boards of the bed-clothes drawer in the specific position required by the user.

To attain correct functioning of the orthopedic collapsible chair it is of benefit that the upper edge of at least one of the side walls of the cabinet drawer should be between the individual supporting holes equipped with fitting apertures for inserting the fitting peg to fasten the bed¬ clothes drawer into the selected position.

As a consequence of the fact that the upper edge of at least one of the side walls of the cabinet drawer is between the individual supporting holes equipped with fitting apertures, one can fasten the cabinet drawer in a certain slightly drawn out position by means of the fitting peg with a handle, which we first poke through the fitting aperture on one of the weight-bearing bars of the drawer cabinet and then we slide it into the nearest fitting aperture on the upper edge ofthe side board ofthe bed-clothes drawer. vπ.

In order to fasten the orthopedic surface ofthe grating or mattress to the weight-bearing frame of the orthopedic collapsible chair it is of benefit that on the upper surface of the horizontal weight-bearing board there are at least two clamps to fasten the lower part of the orthopedic grating or to fasten the lower part ofthe orthopedic mattress to this board. As a consequence of the fact that on the upper surface of the horizontal weight-bearing board there are at least two clamps, one can by means of these clamps fasten the lower surface of the orthopedic grating to the horizontal weight-bearing board, or as the case m.ay be, the lower surface to the orthopedic mattress.

If the orthopedic mattress is placed directly on the weight-bearing frame ofthe collapsible chair it is of benefit that the horizontal weight-bearing board made up of at least one piece should be constructed of a frame, inside which there are transversally-placed springing strips vertical to the front-rear axis of this horizontal weight-bearing board.

As a consequence of the fact that the horizontal weight-bearing board made up of at least one piece is constructed of a frame, inside which there are transversally-placed springing strips vertical to the front-rear axis of this horizontal weight-bearing board, one may place directly upon this horizontal weight-bearing board any special orthopedic mattress without an orthopedic grating. From the health-care point of view however it is not suitable for a special orthopedic grating to be placed directly upon the horizontal weight-bearing board with springing strips, either with a special orthopedic mattress or without it. vm.

In order to fasten the orthopedic surface ofthe grating or mattress to the weight-bearing frame of the orthopedic collapsible chair it is of benefit that on the upper surface of each of the two supporting boards there are located at least two clamps to fasten the bottom part of the orthopedic grating or to fasten the bottom side of the orthopedic matress to these supporting boards.

As a consequence of the fact that on the upper surface of each of the two supporting boards there are located at least two clamps, one may by means of these clamps fasten the bottom side of the orthopedic grating or as the case may be the bottom side of the orthopedic mattress to these supporting boards.

If the orthopedic mattress is placed directly upon the weight-bearing frame of the collapsible chair it is of benefit that at least one ofthe two supporting boards should be constructed of a frame inside which there are transversally-placed springing strips vertical to the front-rear axis of this supporting board.

As a consequence of the fact that at least one of the two supporting boards should be constructed of a frame inside which there are transversally-placed springing strips vertical to the long axis of this supporting board one may place irectly upon this supporting board any orthopedic mattress without an orthopedic grating. From the health-care point of view however it is not suitable for a special orthopedic grating to be placed on a supporting board with springing strips, either with an orthopedic mattress or without one.

LX.

For the supporting boards in their folded state to be a support for sitting it is necessary to first lean them against the weight-bearing frame ofthe orthopedic collapsible chair. For this purpose on each side of the free edge of each ofthe two supporting boards there is located a supporting projection for the supporting boards to rest in the supporting holes which are to be found both on the side weight-bearing bars ofthe drawer cabinet and on the upper edge ofthe side walls of the cabinet drawer.

As a consequence of the fact that on each side of the free edge of each of the two supporting boards there is located a supporting projection, one may lean the full weight of each supporting board by means of their supporting projections into the supporting holes that are to be found both on the side weight-bearing bars of the drawer cabinet and on the upper edge of the side walls ofthe cabinet drawer.

For the correct functioning of the orthopedic collapsible chair it is important that both supporting boards have raised sides in the form of an enclosure.

As a consequence of the fact that both supporting boards have raised sides in the form of an enclosure, the design arrangement prevents the special orthopedic grating or the special orthopedic mattress placed on the supporting boards from moving to one side. For the sake of easier handling of both supporting boards it is of benefit for each supporting board to have at least one slot for gripping and handling this board.

As a consequence of the fact that each supporting board has at least one slot for gripping and handling, folding, unfolding and other actions to these supporting boards are eased and speeded up.
