Description
9 ~ ~ ~
f ~
This invention relates to an inflatable chair, and in particular to a chair for use on land or in water. ~--Inflatable chairs are disclosed by United States Patents Nos. 3,408,107, issued to B.D. Savage on October 29, 1968; 3,572,836, issued to M.N. Khanh on March 30, 1971 and 3,712,674, issued to S. Ando on January 23, 1973. Inflatable air mattresses are commonplace. However; inflatable chairs which can be used in either environment, i.e. on land or in water are rare or non-existent.
¦ 10 An object of the present invention is to provide an -~
inflatable chair, which is relatively simple in terms of - ~-~
! structure, and which can be used on land and in the water.
Another object of the invention is to provide such a chair, which can readily and quickly be unfolded to a use - ~-~
position, and folded to a storage or carrying position.
Yet another object of the invention is to provide a ~;
chair which can easily be releasably latched in the folded or ~ `
use positions, and which uses the same or similar parts for the chair and backrest portions thereof, and in hinge and latch structures. thus, the chair includes relatively few parts, and the same parts are used for a variety of purposes.
Accordingly, the invention relates to an inflatable chair comprising first and second identical inflatable sections, each section defining a closed tubular loop; hinge means interconnecting said sections end-to-end so that one said section defines a seat and the other said section defines ~8~
a backrest; and stand means pivotally connected to said backrest for movement between a folded position against said backrest and an extended position in which the stand means supports the backrest in a back supporting, inclined position.
The invention also provides a novel connector device for releasably and pivotally interconnecting two articles comprising first and second pad means for mounting on the articles, block means on each said pad means; male buckle -~
means pivotally connected to one said pad means; and female buckle means pivotally connected to the other said pad means for releasably coupling with said male buckle means.
The invention will be described in greater detail ,~

Figure 15 is a perspective view of the float shown in Fig. 14; and Figure 16 is a perspective~ view of a buckle-type connector used to couple the ha~r to the float of Fig. 15.
Figure 17 is a plan view of a raft formed by a plurality ofinterconnected chairs of the type shown in Figs. 1 to 4.
With reference to Figs. 1 to 4, the chair of the present invention includes two identical sections, which define a seat 1 and a backrest 2, respectively. Each section is defined by an inflatable tubular body, which is generally oval with one more or less straight end 3. A conventional flap valve (not shown) of the type commonly used in beach ;
balls and air mattresses is provided in each of the seat 1 and 2 ~
the backrest 2 for inflating the chair. A fabric panel 5 covers the central opening 6 in each of the sections. In the case of the seat 1, the panel 5 is on the top, and in the case of the backrest 2, the panel 5 covers the front of the opening 6. The seat 1 and the backrest 2 are pivotally interconnected by a pair of hinges generally indicated at 8.
As best shown in Figs. 5 and 6, each hinge 8 includes a flexible oval patch 3 which is glued to the seat 1 ;
or the backrest 2, as the case may be. Each patch 9 carries a block or projection 10, which is generally semicylindrical, resembling the body of a pillow block bearing. The projection 10 has a hole 11 (Fig. 7) therethrough carrying a pin or axle 12. One pin 12 is used to pivotally connect a male connector 13 to the seat 1, and the other pin 12 pivotally connects a female connector 14 co the backrest 2. It will be appreciated that the locations of the male and female connectors 13 and 14, respectively can be reversed. In the seat of Fig. 12, the male connector 13 is on the backrest 2 and the female connector 14 is on the seat 1. Together the connectors 13 and 14 define a buckle of the type commonly used, for example on life jackets.
The male connector 13 is in the form of a skeletal, generally C-shaped body 16, the arms 17 of which have circular (Figs. 5 and 6) or semicircular free ends 19 (Fig. 7~ with aligned holes 20 for receiving one of the pins 12. Resilient fingers 21 extend outwardly from near the corners of the body 2 ~
16 for insertion into the female connector 14. The distance between the outside edges of the inner ends of the fingers 21 is only slightly less than the width of the open end 23 of the female connector 14. The fingers 21 converge slightly towards the longitudinal axis of the connector 13, and are provided with enlarged heads 24. The heads 24 are pointed for facilitating insertion of the fingers 21 into the open end 23 of the female connector 14. A crossbar 26 (which defines part ~ - -of the C-shaped body 16) supports and is integral with the fingers 21 and a central guide finger 27. The finger 27 ~ --includes longitudinally extending central recesses 28 in the top and bottom surfaces thereof for reducing both sliding friction between the connectors and the quantity of material used in the connectors 13 and 14.
The female connector 14 includes a tubular, rectangular cross section body 30, the open end 23 of which receives the male connector 13. The other end 31 of the body 30 is open, and includes a pair of arms 32 with aligned holes 33 for receiving another pin 12. Recesses 35 are provided in the sides of the body 30 with openings 36 therein. A pair of spaced apart ribs 37 e~tend longitudinally of the interior surfaces of both the top and bottom of the body between the open ends thereof. The ribs 37 act as guides for the central rectangular finger 27 on the male connector 13.
Thus, when the connectors 13 and 14 are coupled, ;~
i.e. the fingers 21 are inserted into the open end 23 of the 2 ~
, . . .
female connector, the fingers 21 flex inwardly towards the longitudinal centre lines of the connectors. When the connector 13 has been fully inserted into the connector 14, the heads 24 are aligned with the openings 36 and spring outwardly to lock the connectors together. The shoulders ~-' defined by the corners of the body 16 at the ends of the :. ,, crossbar 26 limit movement of the male connector 13 into the ~ I
female connector 14. To release the connectors, the heads 24 are pressed towards each other and the connectors are then 10pulled apart to reverse the action described above. The connectors 13 and 14 are used as parts of the hinges 8, as latches generally indicated at 38 (Figs. 8, 9 and 17) and as couplers 39 (Fig. 17). When used as latches 38, the connectors 13 and 14 are used on the front of the backrest 2 ~ lSand the top of the seat 1, respectively. When the seat ~and ! the backrest 2) are folded together (Figs. 8 to 10), the ¦ connectors 13 and 14 are coupled to releasably lock the seat and backrest in the folded carrying or storage position. When used as couplers, the connectors 13 and 14 interconnect seats 201 and backrest 2 end to end and side by side to form a raft (Fig. 17). In one embodiment of the invention, a male connector 13 is provided on one side of the seat 1 and a female connector is provided on the other side of the seat.
Thus, the seats can be interconnected side by side to form the raft of Fig. 17.
~ ' ~ `

A generally U-shaped stand 40 is connected to the backrest 2 for supporting the latter in the inclined use position (Figs. 1 to 4). The stand 40 includes a pair of arms -~
41 interconnected at their outer free ends by a crossbar 42.
The inner ends of the arms 41 include outwardly bowed portions 44 facilitating carrying and handling of the seat in the closed position. The arms 41 are pivotally connected to the backrest by hinges generally indicated at 45. Each hinge 45 includes a patch 46 glued to the backrest. The patch 46 carries a projection or lug 48 with a hole therethrough for receiving a pin 49. A slot 51 in the centre of the lug 48 receives the thin, inner end of the arm 41. The pin 49 passes ~ --through the hole in the lug 48 and an aligned hole (not shown) in the arm 41. The centre of the crossbar 42 is connected to the bottom centre of the backrest 2 by a strap 52.
The strap 52 extends between a male connector 54 on the bottom centre of the backrest 2 and a female connector 55 on the centre of the crossbar 42. The male connector 54 (Figs. 5 and 12), is pivotally mounted on a projection or lug 56 by means of a pin 57. The lug 56 is supported by a pad 58 glued to the backrest 2. The female connector 55 is pivotally mounted on a pin 59 extending through a pair of lugs or ears 60. The ears 60 project forwardly from the crossbar 42. When the chair is in the folded position (Figs. 8 to 10), the male connector 54 is coupled to the female connector 55 (Fig. 12), 2 ~
so that the strap 52 forms a loop which can be placed on a shoulder to facilitate carrying of the chair.
The female connector 55 can also be used to connect the crossbar 42 to a hollow, inflatable float 62 (Fig. 13).
The float 62 is used in the water as a buoyancy aid.
Preferred forms of float 63 are illustrated in Figs. 14 and 15. The float 63 of Fig. 14 is defined by a hollow body 64, which includes longitudinally extending, alternating peaks and troughs, i.e. the top and bottom panels of the body 64 are scalloped in cross section. A conventional flap valve (not shown) is provided in the body 64 for inflating and deflating the float. A pair of male connectors 67 are pivotally mounted on the longitudinal centre of the body 64 for attaching the crossbar 42 to the float. With the chair in the use position, lS one of the male connectors 67 is coupled to the female -connector 55 on the crossbar 42. The use of two male connectors 67 permits the changing of the angle of inclination of the stand 40 and consequently the inclination of the backrest 2. A female connector 68 is connected to the male connector 54 on the bottom centre of the backrest to attach the chair to the float. Each male connector 67 is pivotally connected to a lug 69 by a pin 70. The lug 69 is mounted on a pad 72, which is glued to the float body 64.
In the float of Fig. 15, a pair of spaced apart female connectors 74 is provided near the front end of the float body 64. The connectors 74 are pivotally mounted on 2~3~
lugs 75 supported by pads 76 glued to the body 64. The female connectors 74 are coupled to a pair of male connectors (not ;~
shown) on the bottom of the backrest 2. With this arrangement, the front end 78 of the float extends a short distance (15-18 ) beneath the seat 1 of the chair to provide ;~;
added buoyancy. In the absence of any float under the seat 1, the rear end of the seat tends to sink when a person sits on the chair in water, because the weight of the person is concentrated at the rear of the seat. The front end 78 of the float 63 keeps the seat 1 more or less horizontal in the water.
It will be appreciated that with the above described structure, the chair can be used on land or in the water. The chair is easily unfolded and refolded, and can readily be releasably locked in either position. The chair can also be opened flat, and connected end to end and side to side with similar chairs to form a raft (Fig. 17). It is also possible to disconnect the seat 1 from the backrest 2, and use each section in the same manner as an inner tube. sy turning the section over, the resulting small raft has a base on which a child can kneel, sit or lay.

With reference to Figs. 1 to 4, the chair of the present invention includes two identical sections, which define a seat 1 and a backrest 2, respectively. Each section is defined by an inflatable tubular body, which is generally oval with one more or less straight end 3. A conventional flap valve (not shown) of the type commonly used in beach ;
balls and air mattresses is provided in each of the seat 1 and 2 ~
the backrest 2 for inflating the chair. A fabric panel 5 covers the central opening 6 in each of the sections. In the case of the seat 1, the panel 5 is on the top, and in the case of the backrest 2, the panel 5 covers the front of the opening 6. The seat 1 and the backrest 2 are pivotally interconnected by a pair of hinges generally indicated at 8.
As best shown in Figs. 5 and 6, each hinge 8 includes a flexible oval patch 3 which is glued to the seat 1 ;
or the backrest 2, as the case may be. Each patch 9 carries a block or projection 10, which is generally semicylindrical, resembling the body of a pillow block bearing. The projection 10 has a hole 11 (Fig. 7) therethrough carrying a pin or axle 12. One pin 12 is used to pivotally connect a male connector 13 to the seat 1, and the other pin 12 pivotally connects a female connector 14 co the backrest 2. It will be appreciated that the locations of the male and female connectors 13 and 14, respectively can be reversed. In the seat of Fig. 12, the male connector 13 is on the backrest 2 and the female connector 14 is on the seat 1. Together the connectors 13 and 14 define a buckle of the type commonly used, for example on life jackets.
The male connector 13 is in the form of a skeletal, generally C-shaped body 16, the arms 17 of which have circular (Figs. 5 and 6) or semicircular free ends 19 (Fig. 7~ with aligned holes 20 for receiving one of the pins 12. Resilient fingers 21 extend outwardly from near the corners of the body 2 ~
16 for insertion into the female connector 14. The distance between the outside edges of the inner ends of the fingers 21 is only slightly less than the width of the open end 23 of the female connector 14. The fingers 21 converge slightly towards the longitudinal axis of the connector 13, and are provided with enlarged heads 24. The heads 24 are pointed for facilitating insertion of the fingers 21 into the open end 23 of the female connector 14. A crossbar 26 (which defines part ~ - -of the C-shaped body 16) supports and is integral with the fingers 21 and a central guide finger 27. The finger 27 ~ --includes longitudinally extending central recesses 28 in the top and bottom surfaces thereof for reducing both sliding friction between the connectors and the quantity of material used in the connectors 13 and 14.
The female connector 14 includes a tubular, rectangular cross section body 30, the open end 23 of which receives the male connector 13. The other end 31 of the body 30 is open, and includes a pair of arms 32 with aligned holes 33 for receiving another pin 12. Recesses 35 are provided in the sides of the body 30 with openings 36 therein. A pair of spaced apart ribs 37 e~tend longitudinally of the interior surfaces of both the top and bottom of the body between the open ends thereof. The ribs 37 act as guides for the central rectangular finger 27 on the male connector 13.
Thus, when the connectors 13 and 14 are coupled, ;~
i.e. the fingers 21 are inserted into the open end 23 of the 2 ~
, . . .
female connector, the fingers 21 flex inwardly towards the longitudinal centre lines of the connectors. When the connector 13 has been fully inserted into the connector 14, the heads 24 are aligned with the openings 36 and spring outwardly to lock the connectors together. The shoulders ~-' defined by the corners of the body 16 at the ends of the :. ,, crossbar 26 limit movement of the male connector 13 into the ~ I
female connector 14. To release the connectors, the heads 24 are pressed towards each other and the connectors are then 10pulled apart to reverse the action described above. The connectors 13 and 14 are used as parts of the hinges 8, as latches generally indicated at 38 (Figs. 8, 9 and 17) and as couplers 39 (Fig. 17). When used as latches 38, the connectors 13 and 14 are used on the front of the backrest 2 ~ lSand the top of the seat 1, respectively. When the seat ~and ! the backrest 2) are folded together (Figs. 8 to 10), the ¦ connectors 13 and 14 are coupled to releasably lock the seat and backrest in the folded carrying or storage position. When used as couplers, the connectors 13 and 14 interconnect seats 201 and backrest 2 end to end and side by side to form a raft (Fig. 17). In one embodiment of the invention, a male connector 13 is provided on one side of the seat 1 and a female connector is provided on the other side of the seat.
Thus, the seats can be interconnected side by side to form the raft of Fig. 17.

A generally U-shaped stand 40 is connected to the backrest 2 for supporting the latter in the inclined use position (Figs. 1 to 4). The stand 40 includes a pair of arms -~
41 interconnected at their outer free ends by a crossbar 42.
The inner ends of the arms 41 include outwardly bowed portions 44 facilitating carrying and handling of the seat in the closed position. The arms 41 are pivotally connected to the backrest by hinges generally indicated at 45. Each hinge 45 includes a patch 46 glued to the backrest. The patch 46 carries a projection or lug 48 with a hole therethrough for receiving a pin 49. A slot 51 in the centre of the lug 48 receives the thin, inner end of the arm 41. The pin 49 passes ~ --through the hole in the lug 48 and an aligned hole (not shown) in the arm 41. The centre of the crossbar 42 is connected to the bottom centre of the backrest 2 by a strap 52.
The strap 52 extends between a male connector 54 on the bottom centre of the backrest 2 and a female connector 55 on the centre of the crossbar 42. The male connector 54 (Figs. 5 and 12), is pivotally mounted on a projection or lug 56 by means of a pin 57. The lug 56 is supported by a pad 58 glued to the backrest 2. The female connector 55 is pivotally mounted on a pin 59 extending through a pair of lugs or ears 60. The ears 60 project forwardly from the crossbar 42. When the chair is in the folded position (Figs. 8 to 10), the male connector 54 is coupled to the female connector 55 (Fig. 12), 2 ~
so that the strap 52 forms a loop which can be placed on a shoulder to facilitate carrying of the chair.
The female connector 55 can also be used to connect the crossbar 42 to a hollow, inflatable float 62 (Fig. 13).
The float 62 is used in the water as a buoyancy aid.
Preferred forms of float 63 are illustrated in Figs. 14 and 15. The float 63 of Fig. 14 is defined by a hollow body 64, which includes longitudinally extending, alternating peaks and troughs, i.e. the top and bottom panels of the body 64 are scalloped in cross section. A conventional flap valve (not shown) is provided in the body 64 for inflating and deflating the float. A pair of male connectors 67 are pivotally mounted on the longitudinal centre of the body 64 for attaching the crossbar 42 to the float. With the chair in the use position, lS one of the male connectors 67 is coupled to the female -connector 55 on the crossbar 42. The use of two male connectors 67 permits the changing of the angle of inclination of the stand 40 and consequently the inclination of the backrest 2. A female connector 68 is connected to the male connector 54 on the bottom centre of the backrest to attach the chair to the float. Each male connector 67 is pivotally connected to a lug 69 by a pin 70. The lug 69 is mounted on a pad 72, which is glued to the float body 64.
In the float of Fig. 15, a pair of spaced apart female connectors 74 is provided near the front end of the float body 64. The connectors 74 are pivotally mounted on 2~3~
lugs 75 supported by pads 76 glued to the body 64. The female connectors 74 are coupled to a pair of male connectors (not ;~
shown) on the bottom of the backrest 2. With this arrangement, the front end 78 of the float extends a short distance (15-18 ) beneath the seat 1 of the chair to provide ;~;
added buoyancy. In the absence of any float under the seat 1, the rear end of the seat tends to sink when a person sits on the chair in water, because the weight of the person is concentrated at the rear of the seat. The front end 78 of the float 63 keeps the seat 1 more or less horizontal in the water.
It will be appreciated that with the above described structure, the chair can be used on land or in the water. The chair is easily unfolded and refolded, and can readily be releasably locked in either position. The chair can also be opened flat, and connected end to end and side to side with similar chairs to form a raft (Fig. 17). It is also possible to disconnect the seat 1 from the backrest 2, and use each section in the same manner as an inner tube. sy turning the section over, the resulting small raft has a base on which a child can kneel, sit or lay.
