Filed Apr. 14, 1961, Ser. No. 102,985 4 Claims. (Cl. 297-457) This invention relates to seats for human occupants and particularly for children, and more particularly to foldable or collapsible seats of this type.
A main object of the invention is to provide a seat made from a one-piece blank which can be folded to a compact storage or transit condition and unfolded and interlocked ltQ provide a sturdy seat structure.
Another object is to provide a seat as above described in which the blank may be made of corrugated paperboard.
A further object of the invention is to provide a seat as above described which is strong enough to enable a child to stand on the seat without danger of collapse.
A still further object of the invention is to provide a seat as above described which, although being made of one piece, can be folded together to have a peripheral size substantially less than that of the blank in its flat form and yet which folded blank has a thickness equal to only a few thicknesses of the corrugated paperboard.
Another object of the invention is to provide a seat as above described in which the corrugations run relative to the blank in a direction for maximum strength.
Other objects are to provide a seat of the type under consideration which can be used as a childs toilet, and also is adaptable for placement on a standard toilet, and which can be used as a booster seat in cars, busses, movies and other places, and also as a booster seat on a conventional chair to position a child at a proper height for eating at a standard table.
Various other objects of the invention will be apparent from the following description taken in connection with the accompanying drawings wherein:
FIG. 1 is a perspective view of the blank as having been unfolded from its storage condition;
FIG. 2 is a perspective view from the opposite side from that shown in FIG. 1 and showing a subsequent stage of the erection of the seat;
FIG. 3 is a perspective view of the erected seat, taken in a direction 180 degrees from that shown in FIG. 2; and
FIG. 4 is a plan view of the blank in its flat condition.
Referring to the drawings, the seat blank is best shown in FIG. 4 and is made of corrugated paperboard. The chair is so designed that the blank may be of single strength corrugated paperboard, that is, paperboard having a single corrugated paper filler sandwiched between two cover sheets.
The blank comprises a base panel 1 joined to a pair of seat support panels 103 and separated from the base panel by score lines 105. These score lines are on the opposite side of the blank from the side nearest the viewer as the parts are shown in FIG. 4 and therefore will be called far side score lines, whereas score lines on the side nearest the viewer in FIG. 4 will be referred to as near side score lines.
The score lines 105 taper inwardly and downwardly as the parts are shown in FIG. 4 for reasons to be presently described. The base panel 101 is of trapezoidal shape whereas the panels 103 are of rectangular shape. Each of the seat-supporting panels 103 has two tabreceiving slots 107 and 109' for purposes to be presently described.
The base panel 101 is joined to a front panel 111 and separated from said front panel by a far side score line.
L13. Panel 111 is joined to a pair of auxiliary seatsupporting panels and separated therefrom by suitable far side score lines 117 which are parallel to one another. Each panel 115 has a tab-receiving slot 119 and is cut to provide a generally semicircular tab 121. As a matter of fact, the tab has a periphery that extends beyond the diameter of the semicircle somewhat as is apparent from FIG. 4.
The front panel 111 is joined to a seat panel 131 and separated therefrom by double far side score lines '133. Panel 131 is joined to a pair of arm panels 135 and sepa rated therefrom by near side score lines 137. The arm panels 135 are not joined to the auxiliary seat-supporting panels 115, but are entirely separated therefrom by through cut lines 139. Each arm panel has double far side score lines 141 running vertically as the parts are shown and being positioned closer to the inner edge of the panels than the outer edge. Each arm panel is cut to provide a tab 143 and the cut is so designed as to provide a lug 145 on the tab.
The seat panel may have an interrupted circular cut line 147 to enable a circular portion to be removed to enable the seat to be used for toilet purposes.
The seat panel is joined to a back panel 151 and separated therefrom by a near side score line 153. The back panel is cut to provide a tab 155 of generally semicircular form but somewhat greater than a semicircle. The base of the tab 155 has double score lines 157 for a purpose to be presently described. The tabs 121 previously mentioned also have double score lines at the bases thereof. The back panel 151 has double score lines 159 extending horizontally as the parts are shown in FIG. 4 and approximately medially through the back panel.
The back panel is flanked by back reinforcing panels 161 which are joined to the inner portions of the arm panels 135 and separated from said arm panels by score lines 163. These are near side score lines. The panels 161 are entirely separated from the back panel 151 by through out lines 165. For convenience in description hereinafter, the left-hand panel 161 will be referred to by the reference numeral 161a and the right-hand panel will be referred to by the reference numeral 161]).
The left panel 161a is cut to provide a semicircular slot or opening 171, and the right panel 161a is formed with a slot 173 for receiving the tab 155.
For storage, the panels 161a and 16112 and 135 are folded against the near sides of the panels 151 and 131 respectively, and the panels 115 and 103 are folded against the far sides of the panels 111 and 101 respectively. The resulting structure is folded along the double score lines 133 to form a small compact package having an area equal to that of the panels 131 and 151, and :a thickness equal to four times the thickness of the corrugated paperboard of which the blank i formed. The resulting small package may be releasably held in its folded condition by a paper wrapper which may bear instructions concerning the assembly of the seat. It is contemplated that the instructions may also be printed on the blank itself, .although it is further contemplated that advertising material will be placed on most of accessible areas of the chair.
When the wrapper is removed, the blank will assume the condition approximately shown in FIG. l. Then, the panels 111 and 101 are folded at right angles to one another along the score line 113 while the panels 151 and 131 are arranged at right angles to one another by folding along the score line 153. Next, the seat can be positioned to look at the back thereof as shown in FIG. 2. The panel 115 are then folded against the panels 103 and the tabs 121 inserted through the slots 109. It is pointed out that because of the tapered score lines 105, the panels 103 will be disposed inwardly of the edges of the seat panel 131 and the panels 115 will be similarly disposed 3 by being interlocked with the panels 103 so that these panels 103 and 115 firmly and stably support the seat panel.
Next, the flap 161a is folded against the lower part of the back panel 151 and then the flap or panel 161b is folded against the panel 161a and then the upper portion of the back panel is folded downwardly along the double score line 159 and the tab 155 inserted through the slot 173 and the opening 171 to lock these parts in the desired positions.
Next, the seat panel may be locked in place by folding the arm panels 135 about the score line 141 and inserting the tabs 143 through the upper slots 119 and 107 of the panels 115 and 103. The lugs 145 hook against the inner surfaces of the panels 103 to securely hold the pants in place.
As is evident from the legend 180 in FIG. 4, the corrugations run vertically as the parts are shown in FIG. 4. With the corrugations so running, the seat panel 131 is extremely strong and is able to support a child whether the child is sitting on the seat panel or standing on the seat panel. In fact, an adult will be supported by the assembled seat. It is further pointed out that with the corrugations running as mentioned, the corrugations will run vertically in the auxiliary seat-supporting panels 115 when the seat is assembled and horizontally in the seat-supporting panel 103 when the seat is assembled. This crossing of the corrugations provides an extremely strong structure.
Having described the invention in what is considered to be the preferred embodiment thereof, it is desired that it be understood that the invention is not to be limited other than by the provisions of the following claims.
