referring to fig1 - 3 , a bench 10 capable of accommodating at least two persons of similar or differing heights working at a single workstation such as a desk having a computer terminal thereon is shown . the bench 10 comprises a seat 12 extending substantially horizontally . the seat 12 is supported by support members 14 . in a preferred embodiment , the support members 14 comprise a plurality of legs attached to and extending from an underside 16 of the seat 12 . the support members 14 may further include wheels 32 at an end remote from the seat 12 to facilitate movement of the bench 10 to different locations . of course , the present invention also contemplates the use of other types of support members . for example , only two legs extending along opposite sides of the seat 12 may be utilized , or the legs may extend from other points on the underside of the seat . the bench 10 further comprises a back 18 attached to the seat 12 . the back 18 extends substantially vertically from the seat 12 . the back 18 is substantially the same length as the seat 12 . first and second pivotal members 20 , 22 are also attached to the seat 12 . the first pivotal member 20 corresponds to a first seating position 24 and the second pivotal member 22 corresponds to a second seating position 26 of the bench 10 . thus , the bench 10 can accommodate two persons at a time , one person at each seating position . of course , the present invention contemplates a bench that may be used by more than two people . thus , a bench to accommodate three persons would have three seating positions with three corresponding pivotal members attached to the back member and so on . the pivotal members 20 , 22 are attached to the seat 12 at junction 23 via a shared piece of material . the material is thin at the junction 23 to allow the pivotal members 20 , 22 to pivot between a substantially horizontal position adjacent to a top side 13 of the seat 12 and a substantially vertical position adjacent to a front side or first side 17 of the back 18 . a first attachment mechanism 28 is located on each of the pivotal members 20 , 22 and a second attachment mechanism 30 is located on the first side 17 of the back 18 at each seating position . when one of the pivotal members 20 , 22 is in the substantially vertical position the first and second attachment mechanisms 28 , 30 are coupled . therefore , the pivotal member maintains the vertical position . since fig1 illustrates pivotal member 20 in the vertical position , the first and second attachment mechanisms 28 , 30 at seating position 24 are coupled . the attachment mechanisms may be , for example , a velcro system or a hook and latch system . when the first and second attachment mechanisms are uncoupled , as at second seating position 26 , the pivotal member 26 pivots to the substantially horizontal position adjacent to the top side 13 of the seat . as shown in the figures , the first seating position 24 has the pivotal member 20 in the substantially vertical position and the second seating position ahs the pivotal member 22 in the substantially horizontal position . the bench further includes arm rests 34 located at either end of the seat 12 . an additional arm rest ( not shown ) may be located between each seating position . the arm rests may possess work areas ( not shown ) attached thereto to provide space for a keyboard , mouse or the like . the bench 10 further comprises first and second flip members 38 , 40 attached to a top of the back 18 . the first flip member 38 is substantially vertical and positioned adjacent to a back side or second side 21 of the back 18 , opposite the pivotal member 20 . the second flip member 40 is substantially vertical and positioned adjacent to the front side 17 of the back 18 . thus , the flip members 38 , 40 may be rotated about the top of the back 18 to change between a position adjacent to a first side 17 of the back 18 and a position adjacent to a second side 21 of the back 18 . the bench 10 further includes foot rests 36 corresponding to each seating position . the foot rests 36 are slidably mounted to the underside of the seat 16 . in operation , the bench 10 can be modified to accommodate two children ; two adults or one child and one adult . as shown in fig1 - 3 , the bench 10 has been modified to accommodate an adult at the first seating position 24 and a child at a second seating position 26 . the first pivotal member 20 is in the substantially vertical position adjacent to the first side 17 of the back 18 . the first and second attachment mechanisms 28 , 30 are coupled to secure the pivotal member 20 in the vertical position . the first flip member 38 rests adjacent to the second side 21 of the back 18 . at the second seating position 26 , the first and second attachment mechanisms 28 , 30 have been uncoupled to allow the second pivotal member 22 to pivot about the junction 23 to the substantially horizontal position adjacent to the top side 13 of the seat 12 . the second flip member 40 is then rotated about the top of the back 18 to be positioned adjacent to the first side 17 of the back 18 . the corresponding foot rest 36 may then be slid out . thus , the height of the seating area of the second seating position has been increased to afford a child or shorter person the ability to be comfortably seated at an adult - sized desk next to an adult in the first seating position . moreover , the second flip member 40 provides the child with adequate back support and foot rest 36 provides an area for the child to place his or her feet . therefore , a child or shorter person may be seated simultaneously next to an adult at an appropriate height so that the child may easily view a computer screen , without the need for a second chair and pillows to increase the height of the second chair . fig4 - 6 show another embodiment of the invention . the bench 110 comprises a seat 112 having support members 114 extending from the underside 116 . the bench 110 further includes first and second substantially vertical backs 118 , 119 connected to the seat at first and second seating position 124 , 126 , respectively . the backs define a first side 117 and a second side 121 and are attached to the seat 112 via first and second connecting members 142 , 143 and extendible rods 144 , 145 . the connecting members 142 , 143 extend substantially vertically from the seat 112 and support the extendible rods 144 , 145 . the extendible rods attach the connecting members 142 , 143 to the second sides 121 of the backs 118 , 119 . the extendible rods 144 , 145 allow the backs to be displaced along the horizontal axis . first and second pivotal members 120 , 122 correspond to the first and second seating positions 124 , 126 , respectively . as shown in fig4 the pivotal members 120 , 122 define a bore 146 extending substantially horizontally through a lower end of the pivotal members 120 , 122 . rods 148 are positioned in the bores 146 . the rods 148 have a diameter smaller than the diameter of the bores 146 . the bench 110 further has arm rests 134 located at opposite ends of the seat and interior arm rests 135 located in between first and second seating positions 124 , 126 . the arm rests 134 , 135 define a recess on its interior side or a hole therethrough , coaxially situated with the bores 146 of the pivotal members 120 , 122 . the rods 148 rest in the recess or hole of the arm rests 134 , 135 . thus , rods 148 allow the pivotal members to pivot between a substantially horizontal position adjacent to a top side 113 of the seat 112 and a substantially vertical position adjacent to the first side 117 of the backs . a first attachment mechanism 128 is located on each of the pivotal members 120 , 122 and a second attachment mechanism 130 is located on the first side 117 of each of the backs 118 , 119 . in addition , foot rests 136 are slidably mounted to the underside 116 of the seat 112 . as illustrated , the bench 110 is positioned to accommodate an adult in the first seating position 124 and a child in the second seating position 126 . at the first seating position 124 , the first and second attachment mechanism 128 , 130 are coupled , therefore pivotal member 120 is in a substantially vertical position . at the second seating position 126 the first and second attachment mechanisms have been uncoupled , allowing the second pivotal member 122 to pivot about the rod 148 to the substantially horizontal position adjacent to the top side 113 of the seat 112 . the extendable rod 143 is then expanded to move the second back 119 forward along the horizontal axis over the horizontal pivotal member 122 . the foot rest 136 is also slid forward to provide an area for the child to place his or her feet . thus , the second seating position 126 is arranged to have a seating area with an increased height to accommodate a child comfortably . moreover , the back 119 provides the child with adequate back support since it is forwardly displaced . of course , the present invention contemplates a bench having more than two seating positions . the invention further contemplates a bench wherein all , some or none of the seating positions be arranged to accommodate a child . thus , the bench of the invention may accommodate only children , only adults , or any combination of children and adults to fill each seating position . although the invention herein has been described with reference to particular embodiments , it is to be understood that these embodiments are merely illustrative of the principles and applications of the present invention . it is therefore to be understood that numerous modifications may be made to the illustrative embodiments and that other arrangements may be devised without departing from the spirit and scope of the present invention as defined by the appended claims .
a bench is provided for use by at least two persons of similar or differing heights . the bench includes a seat , a back , pivotal members and a support . the pivotal members are held in a substantially vertical position adjacent to the back by a release mechanism . unlocking the release mechanism results in the pivotal member pivoting to a substantially horizontal position adjacent to the seat . the pivotal member may be locked in this position by a locking mechanism . in addition , in one embodiment of the invention , the back may be horizontally displaced towards the front of the seat , when the pivotal member is in the substantially horizontal position . thus , the bench may accommodate two persons simultaneously , such as an adult and a child .
