Abstract

20200100228 Novelty: there is disclosed an assemblable stool becoming a walking stick and vice versa (fig. 1,2). Constitution: a) a circular disk (fig. 1) divided into three pieces-bases (1,2,3) (fig. 3,4,5) set at an angle of inclination of 120 degrees, interconnected by hinges in a fixed and solid manner, and created by insertion of pins into the cylinders they bear; b) three inclinable integral legs-bases (11 12 13) - (fig. 1,7,8). The foot (11) has a circular cross-section and the legs (12,13) ??a semicircular cross section; c) a handle (14) having a projection (16) and a cylindrical tube entering the foot (11) (fig.1,2) for enabling the adjustment in length by means of a pin (P) and holes (T1, T2, T3, T4, T5) (fig. 1.14) when operating as a cane; d) three hinges (4,5,6) ( fig. 1,3,4,5) placed on the sections of the circular disk (fig.2,3); e) three pins (7,8,9) which, entering the cylinders (4,5,6), create the hinges that tie the bases (1,2,3) in a solid set, creating thus the stool. For better stability, the feet are inclinable to facilitate the contact of the feet with the ground. The foot (11) inclines towards the center but the handle (14) having an orientation opposite to the inclination achieves the contact with the ground, the projection (16) being out of the vertical one of the circular stool’s disk (seat) (fig. 1). By removing the hinge (9) of the pin (6), the two bases (2,3) are released and being folded together with the legs (12,13) ??in a selected order, they rest on the base (1) to create the cane with the mechanism (M) being suspended in the middle of the cane (fig.2). The legs (12,13) ??are successively in contact with their flat sides, they mutually secure via the safety ring (17) (figs. 1, 13) and are -together with the leg (11)- in a straight line, forming the body of the cane. The mechanism (M), which turns the stool into a walking stick and vice versa, has the hinges at different levels on the stool base to achieve a comfortable and strong tightening when folding to create the cane.

Description

DESCRIPTION

The stool that becomes a cane.

The invention refers to a tilting mechanism, which turns a stool (fig. 1) into a cane (fig. 2) and with reverse movements, the cane returns to a stool

Hinges are known for their use and have provided solutions to the necessity of rotating heavy structures. The stool that becomes a cane is based on the hinge technique, which is reliable for the stable performance and precision it provides during its repeated movements over time.

The handle of the cane, which is also the leg of the stool, based on the style adjustment technique as in crutches, has the ability to increase the length of the trunk of the cane up to 20 cm, serving users according to their style and returning to original length of the stool leg.

The purpose of this invention is to enable people who have difficulty walking and standing, who already use a cane, to make it easier with the cane, and in case they get tired, to have a stool immediately, with two or three simple movements. rest The facility is also provided in cases of queues, open gatherings, church gatherings, etc.

Many people, in their pride and selfishness, hesitate to depend on the walking stick. A cane is not easily accepted by people who cross the threshold of the third age and who until recently walked independently and slowly acquire motor weaknesses. With the fear of inconvenience or the thought that they will not make it on the walk or in a queue, they prefer not to walk or go to work. The solution provided by the stool that becomes a cane, but also the opposite, is obvious, for those who find it difficult to stand on their feet.

The ability to convert the cane into a stool and vice versa allows one to more easily overcome the hesitation he has, to suddenly appear with a cane, because he gains confidence, because he will succeed in his movement, since he will have the back-up facility of the stool .

The removable pin (9) of the hinge (6) (fig. 1) is tied with a string so that it does not get lost and is stored (during the cane phase) in the cylinders of one of the two bases that it secures. The hinge (6) functions solely to tighten the stool and not to achieve any rotation and therefore the fixed attachment of the fire inside the group of cylinders (6) with semi-automatic opening and closing by means of a spring may be sought.

Due to the special position that the cylinders (4,5,6) are required to have on the bases (1,2,3) of the stool, in order for the mechanism (M) to work, they do not form a flat seating surface on the stool (fig.1 ,3,4,5). Aesthetically, it may create a problem, but practically no problem arises, because the benefit is many times greater than the aesthetic imperfection.

The surface of the seat of the stool is folded (fig. 2,7,8) and its presence on the trunk of the cane, because it is over-mitigated by its folding to 1/3 of its maximum surface, is aesthetically tolerable or even without discomfort, if put forward its purpose and usefulness.

The stool that becomes a cane, is a stool (fig. 1) which consists of: a) From the seat which is a circular disk that has been cut every 120 degrees into three parts: the base (1), the base (2) and the base (3). b) From three legs (11.12.13), which are integrated respectively in the bases (1,2,3). The leg (11) has a circular cross-section, while the legs (12,13) have a semi-circular cross-section, c) From the handle (14) with a projection (16) and a cylindrical tube the same length as the leg (11), which enters the leg (11) (fig. 1). d) From three groups of hinge cylinders (4,5,6), (each group of four cylinders), placed on the sections of the bases (1,2,3) (fig.1) which cylinders, in pairs and alternately, have been attached to each adjacent base (fig. 3,4,5). e) From three fires (7,8,9), which, entering the groups of cylinders (4, 5, 6), create hinges that bind together the three bases (1,2,3) in a solid whole, creating the stool .

For better stability, the legs (11,12,13) are in contact with the ground, at points outside the vertical projection of the circular disc on the ground, because it has been tilted during their integration on the bases (1,2,3 ) (fig. 1,2, 7, 8). The leg (11) is inclined towards the center of the vertical projection of the circular disk on the ground, but with the selected orientation of the handle (14) and with the presence of the protrusion (16), the contact of the leg (11) with the ground, to be outside the vertical projection of the circular disc on the ground (fig. 1).

When removing a fire, the two stands from which the fire was removed rotate freely. With the special gluing and proper positioning of the hinges (4,5, 6) on all the bases (1,2,3) (fig.1), when the fire (9) is removed, the two bases (2,3 ) rotate and rest on the intermediate base (I). With a predetermined priority order of rotation and with the help of the safety ring (17 ) (fig. 1,2,15), solid tightening of legs and bases (1,2,3) is achieved creating the cane. The legs (11,12,13) become the body of the cane and the bases (1,2,3) create the folded mechanism (M) suspended in the middle of the cane (fig.2,7,8). In this position the safety ring of the leg (12) (fig. 1, 2, 15) hooks the leg (13) from the recesses (10) (fig. 1, 17), everything is stabilized and we have a cane with minimal style determined by the style of the stool legs. With the possibility of the pins (P) (fig. 14) of the handle (14) being moved from the hole (T1) of the leg (11) to the other holes (T2,T3,T4,T5) (fig. 1,2, 13)), the style of the cane increases by 5 cm up to 20 cm.

Unhooking through the safety ring (17), the two trunks (12, 13) (fig.2) of the walking stick, first the trunk (13) with the base (3), rotates by 180 degrees. The same is repeated with the trunk (12) and the base (2), the two free ends of the bases (2,3) "meet" and the rollers form the hinge (6) again. By adding the fire (9) to the hinge (6), the solid state of the circular disc (seat) with the image of the hinges is restored and consequently the stool is recreated (drawing 1 );

In summary, the following applies: a) we have the stool, remove the fire (9), rotate the leg (12), rotate the leg (13), (the safety ring automatically locks (17)), adjust the style of the handle (14) ), the cane is ready! b) we have the walking stick, reduce the handle (14) to a minimum, unlock the safety ring, rotate the leg (13), rotate the leg (12), add the fire (9), the stool is ready! !

Claims (16)

A X I O S E I S I. The stool that becomes a cane is a stool (fig. 1) which consists of the seat or mechanism (M), which is a circular disc, which has been cut into three parts at an angle of 120 degrees, creating the base (1 )(fig. 3), the base (2)(fig. 4) and the base (3) (fig. 5) and which are solidly connected to each other with integrated hinges. A leg (11,12,13) has been integrated into each base respectively. For better stability of the stool, the legs (11,12,13) have been integrated with an inclination in relation to the bases (1,2,3 )(fig. 7 , 8). By removing the pin (9) of the hinge (6), the bases (2,3) together with the legs (12,13), rotate freely through 180 degrees. Rotating first the base (2 ) together with the leg (12), rests on the base (1). Then, rotating the base (3) together with the leg (13), rests on the base (2) (fig. 7,8), forming the cane, which is shown upside down in drawing 2. With the selected position of joining the legs (12,13) with the bases (2,3), the legs (12,13) of the stool (fig. 1), after the rotation their flat sides are in contact with each other and with the leg (11) they are in a position of an extended straight line, turning from legs into the trunk of the cane (fig. 2). The bases (1,2,3), turn from a seat of the stool, in folded mechanism (M) (pictures 7,8), suspended in the middle of the cane trunk (fig.2). With opposite movements to those of the cane formation, and with the re-introduction of the fire (9) into the cylinder group (6) it is all made together again, a solid complex, forming the stool (picture 1). 2. The cane stool according to claim 1, characterized in that the legs (11, 12, 13) are integrally integrated with the bases (1, 2, 3) respectively, not vertically, but at an angle of deviation 8 degrees, with the direction of the legs (12 and 13) moving away from the center of the vertical projection of the circular disc of the stool on the ground, and the leg (11), in the direction of the center of the vertical projection of the circular disc on the ground (figures 1, 7, 8). 3. The cane stool according to claims 1 and 2, characterized in that the legs (12, 13) are of semicircular cross-section (fig. 9, 10) with a diameter of 32 mm and the length of the leg (13) is less than the leg (12) by 1cm. Their integration on the bases (2,3) is of the leg (12) with the curved side tangential to the perimeter of the base (2), and of the leg (13) the curved side towards the center of the base (3) (pictures 1, 9, 10) and at a point where when the bases (12,13) are rotated by 180 degrees on the base (1), the legs (12,13) touch with their flat sides and form a circular trunk (figs. 7, 8) which would form the lower part of the cane trunk 4. The stool that becomes a cane according to claims 1 and 2, is characterized in that, in the leg (11) (which is of a circular cross-section with a diameter of 32 mm and a length of 8 cm shorter than the leg 12) (fig. 12), it fits snugly the equilong cylindrical tube (28mm cross-section) of the handle (14) (fig. 1,2) which has an oblique "T"-shaped end. The overlapping part of the "T" half touches at right angles, and the other half obliquely, at an angle of 135 degrees. The end of the oblique side of the "T" is called a projection (16) (fig. 1,2), which during the stool phase, touches the ground (fig. 1). 5. The stool that becomes a cane according to claims 1, 2, and 4, is characterized by the fact that the leg (11) internally and along its length, has diametrically opposed two triangular guide nerves (N) (fig. 12), and between the guiding nerves (N), every 5 cm, it has diametrically opposite 5 holes T1,T2,T3,T4,T5 (fig. 1, 13), covering a length of 20 cm, which serve to adjust the length of the cane. 6. The stool that becomes a cane according to claims 1,2,4 and 5, is characterized by the fact that, on the surface and along the cylindrical tube of the handle (14), it has two diametrically opposed triangular recesses (E) (fig. 6) ,11), of the same cross-section of the gap, as the cross-section of the guide nerves (N) of claim 5. In the space between the triangular recesses, at the same level as the holes (TI) of the leg (11) has two fires (Π)( fig.1,6,14) diametrically opposed, which while remaining with an internal spring (L) (fig. 14) in extension, when both are pressed simultaneously with the user's fingers, allow the cylindrical tube to enter the trunk or leg (11)(fig. 1). Where the entrance ends, pirs (Π) exit through the holes (TI) (fig. 1) having the shortest length of the trunk or leg (11) as required for the footstool. As long as the pips (Π) are transferred to the holes (T1,T2,T3,T4,T5), the length of the walking stick is changed to adapt to the user's body type. 7. The cane stool according to claims 1, 2, 4, and 6 is characterized in that the entry of the cylindrical tube of the handle (14) into the trunk or leg (11) (fig. 1) is oriented with the help of the guide ribs (N) (fig. 12) and the recesses (E) (fig. 11), with the handle (14) and the projection (16) oriented towards the outside of the perimeter of the base (1) and against the inclination of the leg (11) (fig. 1). In this position the projection (16) on the stool phase contacts the ground at a point outside the circumference of the vertical projection of the circular disc on the ground and acts as an inclined leg, as the same happens with the legs (12, 13 ) , achieving stability in supporting the stool). 8. The walking stick stool according to claims 1, 2 and 3, characterized in that, at the bottom of the leg or trunk (12) (fig. 1 and 2)) there is a safety ring (17) (fig. 15) supported by screws (18) (fig. 16) on the curved side of the trunk (12), extending at both ends beyond the flat side of the trunk (12), with anchoring protrusions (A) on the inner sides (fig. 15) and two integrated fins (PT) (fig.15,16) to the right and left of the support screws. The push-on flaps open the safety ring extensions (17) with the anchoring protrusions (A). 9. The cane stool according to claims 1, 2, 3 and 8, characterized in that, in the lower part of the trunk (13), there are two recesses (10) (fig. 1, 17) on the curved side, in same depth and level as the anchoring protrusions of the safety ring (17) of the trunk (12), so that when in the form of a stick the trunks (12,13) touch one another, the anchoring protrusions (A) of the safety ring (17) (fig. .15) to enter the recesses (10) of the leg (13) and secure the two semicircular trunks (12,13) between them, in a circular trunk. By pressing the flaps (PT) of the safety ring (17), the extensions open and the two trunks (12, 13) are unhooked 10. The stool which becomes a cane according to claims 3 and 9, is characterized by the fact that, on the edge of the trunk (13) there is a circular anti-slip cap (15) 10 mm thick and 32 mm in diameter which has a superimposed semi-circular cap of 28 mm in diameter (fig. . 18) which enters the trunk (13) completing its missing length and protruding through the other half of the semicircle, also covers the cross-section of the trunk (12) in the cane phase (fig. 1, 2, 17) 11. The stool that becomes a cane according to claims 1, 2 and 3, is characterized in that the base (2), with the axis of rotation of the fire (8), rotates first, in the process of conversion from a stool to a cane, and second, by cane on stool. Requiring after the rotation that the base (2) rests between the bases (1) and (3) having the necessary space, the hinge (6) has been moved on the base (2) parallel to the original cut, by as much as the diameter of the hinges plus 1mm, and thus the distance between the hinges of the base (2), is narrower, automatically making the base (3) wider between its hinges as much as the reduction of the base (2) (fig. 1 ). 12. The cane stool according to claims 1 and 11, characterized in that the inner edges of the hinges (4,5,6) are at a distance from the center of the circular disc of the bases (1,2, 3 ) leaving a circular gap (K) with a radius of at least 15 millimeters (fig. 1), to allow the application of claim 11. 13. The stool which becomes a cane according to claims 1 and 11, is characterized in that, in the spaces between the two cylinders of the base (3) of the hinge (6), there are cantilevers (P) (fig. 5) outside the space covered by the rollers of the base (2) of the group (6), which acts as an alignment guide between the group of rollers (6) in the phase of reuniting the bases (2,3) with each other, to make the cane a stool , in order, with the alignment, to more easily insert the fire (9) (fig. 19). 14. The cane stool according to claims 1 and 2 is characterized in that the bases (1,2,3) have a thickness of 9 mm, i.e. it is 1 mm smaller than the diameters of the hinges (4,5,6) , so as to create the condition for folding tolerances of the mechanism (M) and the necessary condition for a durable and safe connection of the bases (1,2,3) with the trunks or legs (11,12,13). The thickness is not over the entire area of the bases, but is achieved by ribs (ΔN) at the bottom of the bases, around them and transversely from the legs (11,12,13) to the rotation rollers (4,5,6,) (fig. 19) 15. The cane stool according to claims 1, 3, 11, 14, characterized in that, the hinges (4, 5, 6) to overlap the bases (1, 2, 3) in the mechanism (M) , during the cane phase, are integrated on the bases (1,2,3) at different levels (fig. 3,4,5). The hinge (4) is all above the surface level of the bases (1 and 3). The hinge (5), half is above and the other half below the level of the surface of the bases (1,2). The hinge (6) is all below the surface level of the bases (2,3) (fig. 3,4,5) 16. The cane stool according to claims (1,3,11 and 14) characterized in that the base (3) has a gap (20) from the circumference of the circular disc, to the flat side of the leg (13) and as long as the trunk or leg (12) covers or obstructs when folding the base (3) onto the base (2) (fig. 1,5,19). The gap (20) facilitates the trunk (12) to be joined unhindered, in the phase of the walking stick, forming a trunk later touching one another with the trunk (13).
