Abstract
A form for making a stepped-bottom basket including a three-dimensional L-shaped frame vertically partitioned into two segments that are releasably fastenable to one another. The first segment includes top, front, rear and side walls that define the shape of the interior of the deep portion of the stepped bottom basket and the second segment includes top, front, rear and side walls that define the shape of the interior of the shallow portion of the stepped bottom basket. The second segment may include an integral splint guide capable of receiving inner reinforcement splints for the bottom of the shallow upper basket portion. Adjacent walls of the segments may be adapted for securely fitting and fastening the segments together.
Description




BACKGROUND OF THE INVENTION




This invention relates generally to forms used in making woven baskets having bottom portions at each of at least two different levels, such that their outer bottom portions may rest upon surfaces at different heights. These baskets will be referred to as “stepped-bottom” baskets.




Stepped-bottom baskets provide conveniently accessible storage for differently sized items. Two-level baskets shaped like an inverted “L” are common. The deeper portion of these baskets may be used to hold larger items, such as reading materials and craft supplies, while the shallower portion may be used to hold smaller items, such as eyeglasses, pens, and scissors. A user seated in a chair easily may reach into a stepped-bottom basket placed alongside the chair to retrieve both the large and small items stored in the basket. Besides being used on flat surfaces for storing differently sized items, these baskets also may be placed on stairs, with the bottom of the deeper portion resting upon one stair tread and the bottom of the shallower portion resting upon the next higher stair tread, and used to assemble items to be taken up or down the stairs.




Woven wooden baskets generally are made by shaping the basket over a basket mold, or form. Weaving splints are conformed to the form either prior to or during basket construction and are intertwined to form various basket panels.




Basket forms typically have a shape that defines the shape of the interior of the basket. Although it might be possible to weave a stepped-bottom basket using a unitary form that conforms to the shape of the basket interior, it would be difficult to produce a high-quality basket using such an unwieldy form.




SUMMARY OF THE INVENTION




It is an object of the present invention to provide a form suitable for use in weaving a stepped-bottom basket, in which the form is partitioned to ease the weaving process and to allow consistent production of high-quality baskets. This objective is achieved in a form that comprises a three-dimensional L-shaped frame that is vertically partitioned into two segments that are releasably fastenable to one another. The first segment includes top, front, rear and side walls that define the shape of the interior of the deep portion of the stepped bottom basket and the second segment includes top, front, rear and side walls that define the shape of the interior of the shallow portion of the stepped bottom basket. The second segment may include an integral splint guide capable of receiving inner reinforcement splints for the bottom of the shallow upper basket portion. Adjacent walls of the segments may be adapted for fitting and fastening the segments together.




These and further objects of the invention will become apparent from the following detailed description.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENT(S)




The invention comprises a form for making a stepped-bottom basket. The invention is shown and described with reference to a two-level embodiment of a stepped-bottom basket, but it also is applicable to forms for other stepped-bottom baskets, such as three-level baskets having either successively shallower bottom portions, or having a deep center section with shallower sections on either side.





FIG. 1

shows a unitary basket


10


having a stepped bottom, that is, a basket having at least two bottom portions at different levels with an intermediate wall separating the upper and lower bottom portions. These bottom portions define basket sections of different depths. The combined basket form of the present invention is shaped to conform substantially to the interior of the above-described basket.





FIGS. 18 and 21B

show a vertically partitioned form


68


for a stepped-bottom basket, according to the present invention. The combined form


68


defines a three-dimensional L-shaped frame, best shown in

FIGS. 16 and 21A

. The first segment


70


, shown in

FIGS. 19A through 19E

, is similar to conventional forms used in making rectangular woven baskets. The first segment


70


includes top


71


and side


72


walls that define the shape of the interior of the deeper section of the basket, and a bottom


73


.




Two recesses


75


A,


75


B (best shown in

FIG. 19D

) may be provided in the bottom


73


for use in supporting the form


70


on the weaving horse. The substantially centered recess


75


A is used to support the first segment


70


on the weaving horse when the first segment


70


is used alone. The second recess


75


B is offset toward the back


74


of the first segment


70


. The first segment


70


may be shifted on the weaving horse from the centered recess


75


A to the offset recess


75


B after the second segment


80


is added, to adjust for the new center of gravity of the combined form


68


.




The second segment


80


, shown in

FIGS. 20A through 20E

, also includes top


81


and side


82


walls that define the shape of the interior of the shallow rear section, and a bottom


83


.




The top


81


of the second segment


80


(shown in

FIG. 20E

) may include an integral guide for forming the upper bottom panel


18


. The guide defines recessed slots


86


for holding the inner reinforcements


60


in place. FIG.


15


. shows an inner reinforcement


60


(partially hidden by the upsplint


30


) inserted into a slot


86


on the second segment


80


.




As shown in

FIGS. 18 and 21A

, the front wall


84


of the second segment


80


may be connected to the back wall


74


of the first segment


70


, with the bottoms


73


,


83


of the segments aligned with one another. The upper back wall


74


A of the first segment


70


is shaped for mating with the front wall


84


of the second segment


80


. The front wall


84


may include a projecting notch or bracket


87


(shown in

FIG. 20A

) that engages a corresponding recess


77


(shown in

FIG. 19C

) in the upper back wall


74


A of the first segment


70


to secure the form segments together. Other methods for connecting the two segments


70


,


80


, such as a dovetail joint, also may be suitable if they do not alter the outer contour of the form


68


. Fasteners, such as a latch


88


A,


88


B, may be provided on the form bottoms


73


,


83


to hold the segments


70


,


80


securely together as shown in

FIGS. 19D

,


20


D, and


21


B.

FIGS. 21F and 22F

show details of a suitable sash-type latch.




A protective band


79


may be provided along the three outer sides of each segment


70


,


80


. The band


79


covers the bottom of the exposed sides of the combined form


68


and protects the form


68


from damage when the splint ends are tacked to the top bands


50


. The band


79


also may be provided with guides or clips


78


that hold an inner top band against the form


68


during weaving. Bores


79


A may be formed in the band


79


to guide the placement of holes to be drilled through the bands


50


and upper splint ends. These holes may be used for fastening handles, lids or other features or accessories to the basket


10


.




The basket constructed using the form of the present invention will be described in detail to aid in understanding how the form is used. Although the basket may be used with only its lower bottom panel resting on a supporting surface, it also may be use with the lower and upper bottom panels each resting upon surfaces at different levels, such as successive stair treads or a floor and an adjacent raised ledge. In the description below, the term “front” will be used to refer to the part of the basket that would be furthest from the stair risers if the basket was placed on stairs and the terms “upper rear” and “lower rear” will be used to refer to the parts of the basket that would be closest to higher and lower stair risers, respectively.




The basket


10


includes a substantially vertical front panel


12


, best shown in

FIG. 7. A

lower bottom panel


14


(shown in

FIGS. 2 and 9

) extends transversely from the bottom of the front panel


12


. The bottom panel


14


extends to the bottom of an intermediate or lower rear panel


16


which is located between the front panel


12


and an upper rear panel


20


. The top of the lower rear panel


16


ends at a distance below the top of the front panel


12


.




An upper bottom panel


18


extends transversely from the top of the lower rear panel


16


. The upper rear panel


20


(best shown in

FIGS. 1 and 8

) extends transversely from the opposite end of the upper bottom panel


18


. The upper rear panel


20


is substantially parallel to the lower rear


16


and front


12


panels. Left


22


and right


24


side panels, best shown in

FIGS. 4 and 6

, each defines an inverted L-shape. The side panels


22


,


24


extend laterally from the front panel


12


to the upper rear panel


20


, in communication with the lower bottom panel


14


, lower rear panel


16


and upper bottom panel


18


.




The front panel


12


, lower rear panel


16


, and front portions of side panels


22


,


24


define a deep front storage area while the upper rear panel and rear portions of side panels


22


,


24


define a shallow rear storage area. The upper region of the front storage area is open to and integral with the rear storage area.




The panels are formed from thin flexible strips, such as wood splints. Upsplints


30


extend continuously from the top of the front panel


12


, along the length of the lower bottom panel


14


, up the lower rear panel


16


, along the length of the upper bottom panel


18


, to the top of the upper rear panel


20


. The cross splints


32


extend from the top of the left side panel


22


, along the width of the lower bottom panel


14


and to the top of the right side panel


24


. Short splints


34


extend from the top of the left side panel


22


, along the width of the upper bottom panel


18


, to the top of the right side panel


24


. Horizontal splints


36


, referred to as weave strips, extend around the front, left, right and a rear panel of the basket


10


at predetermined distances from each other. The weave strips


36


generally are woven through the upsplints


30


, cross splints


32


, and short splints


34


in a conventional alternating over-and-under weave pattern.




The upsplints


30


in the lower rear panel


16


are bent transversely to the lower rear panel


16


just above the top of the uppermost weave strip


40


in the lower rear panel. These upsplints


30


are woven with short splints


34


to form the upper bottom panel


18


.




The stepped-bottom basket


10


may be constructed using the following steps:




(1) Forming the lower bottom panel


14


;




(2) Placing the lower bottom panel over the first form segment;




(3) Constructing the lower rear panel


16


and the portions of the front


12


, left


22


and right


24


panels that extend from the lower bottom panel


14


to the upper bottom panel


18


over the first segment;




(4) Attaching the second form segment to the first segment;




(5) Forming the upper bottom panel


18


from the upsplints


30


in the lower rear panel


16


over the second form segment; and




(6) Constructing the upper rear panel


20


and the remainder of the front


12


, left


22


and right


24


panels from the upper bottom panel


18


to the basket rim


50


over the combined form.




More specifically, the basket


10


may be constructed by first forming the lower bottom panel


14


as shown in FIG.


12


. Construction of this panel


14


is similar to construction of the bottom panel of a conventional rectangular splint basket, with the bottom panel


14


being formed by weaving cross splints


32


through an array of upsplints


30


to define a central woven section with the splints ends extending outwardly therefrom.




The cross splints


32


that extend outwardly from the woven section will form the vertical framework of the side panels


22


,


24


of the deep front portion of the basket


10


, so they must be at least as long as the desired basket height (from the lower bottom panel


14


to the top rim


50


) plus the width of the lower bottom panel


14


. The upsplints


30


that extend outwardly from the woven section will form the vertical framework of the front


12


and upper


20


and lower


16


rear panels of the basket, and the base of the upper bottom panel


18


. The upsplints


30


therefore must be at least as long as the sum of twice the desired basket height and the combined lengths of the upper


18


and lower


14


bottom panels.




As explained further below, the bottom panel


14


may include inner


60


or outer


62


reinforcements, or both, if desired. These reinforcements provide a finished appearance and increase the strength of the bottom panel


14


. Inner reinforcements


60


, shown in

FIGS. 3 and 10

, are positioned on the work surface before forming of the bottom panel


14


begins. Recessed slots may be provided in the work surface to prevent the inner reinforcements


60


from sliding out of place. Upsplints


30


are arranged on the work surface over the inner reinforcements


60


, in spaced parallel relationship to one another. Fill splints


38


, which do not extend beyond the edges of bottom panel, may be arranged between the upsplints


30


to reduce the openness of the bottom panel


14


.




Cross splints


32


are woven through the parallel upsplints


30


and fill splints


38


in a desired pattern, with an alternating, over-and-under pattern being preferred. A double thickness of cross splints


32


and upsplints


30


may be used to increase the strength and rigidity of the finished basket


10


without sacrificing flexibility during weaving. The first cross splint


32


generally is spaced at a distance from the front panel


12


end of the upsplints


30


that is about equal to the desired basket height. This will cause the woven panel


14


to be located asymmetrically with respect to the upsplints


30


, with the upsplints


30


extending beyond the opposite side of the finished panel


14


being about as long as the desired height of the basket plus the combined lengths of the upper


18


and lower


14


bottom panels. Additional cross splints


32


are woven though the upsplints


30


until the desired number of cross splints


32


in the lower bottom panel


14


is reached.




Outer reinforcements


62


(shown in

FIGS. 2 and 9

) may be positioned on the exterior of the woven bottom panel


14


, usually overlaying the upsplints


30


and any inner reinforcements


60


. The outer reinforcements


62


are secured to the splints in the bottom panel


14


and any underlying reinforcements


60


, preferably by fasteners, such as tacks.




The remainder of the basket


10


is constructed using the basket form


68


. As described above, the form


68


is vertically partitioned into detachably connected segments


70


,


80


, as shown in

FIGS. 18 and 21A

. The first segment


70


defines the shape of the interior of the deep, front section of the basket


10


and the second segment


80


defines the shape of the interior of the shallow rear section.




When the form


68


is partitioned vertically, the first segment


70


initially is used alone to form the lower rear panel


16


and the lower portions of the front


12


, left


22


and right


24


panels, that is, the portions of the front


12


, left


22


and right


24


panels that extend from the lower bottom panel


14


to the upper bottom panel


18


. The second segment


80


is connected to the first segment


70


for use in forming the upper bottom panel


18


, the upper rear panel


20


and the remainder of the front


12


and side


22


,


24


panels. Although it also would be possible to partition the form


68


horizontally, i.e., with a first segment defining the interior of the lower bottom portion of the basket only and a second segment defining the interior of the entire upper portion, the vertically partitioned form


68


is preferred for ease of weaving.




As shown in

FIG. 13

, the lower bottom panel


14


is overlaid on the top


71


of the first segment


70


, which is shown supported on a weaving horse in FIG.


13


. The formed panel


14


is secured to the segment


70


by a conventional “hold-down” or clamp. The upsplints


30


and cross splints


32


are bent to conform them to the sides


72


of the segment


70


. The ends of the upsplints


30


corresponding to the upper bottom panel


18


and the upper rear panel


20


extend a distance beyond the bottom


73


.




Weave strips


36


are woven through the splints


30


,


32


in any desired pattern, with an alternating, over-and-under pattern being preferred. These weave strips


36


will form the cross-weaving, or horizontal structure, of the finished basket


10


. As with the cross splints


32


and upsplints


30


, a double thickness of weave strips


36


may be used. Successive rows of weave strips


36


are added until the basket panels reach a height slightly less than the desired height of the lower rear panel


16


.




After the last weave strip


36


is added to the lower rear panel


16


, the second segment


80


is connected to the first segment


70


, as shown in

FIG. 14

, in preparation for forming the upper bottom panel


18


. If desired, the placement of the combined form


68


on the weaving horse may be adjusted to accommodate the new center of gravity of the combined form


68


, as described above.




The top


81


of the second segment


80


preferably includes an integral guide (shown in

FIGS. 14 and 20E

) for holding the inner reinforcements


60


of the upper bottom panel in position on the segment


80


. The upper bottom panel


18


is formed by placing inner reinforcements


60


on the top of the second segment


80


, preferably using the integral guide slots


86


to keep the reinforcements


60


from sliding out of position. The upsplints


30


from the lower rear panel


16


are bent at about a right angle so that they extend across the top of the second segment


80


(and over the inner reinforcements


60


). Fill splints


38


, which do not extend beyond the edges of upper bottom panel


18


, may be arranged between the upsplints


30


to reduce the openness of the upper bottom panel


18


.




Short splints


34


, which will form the vertical structure of the shallow rear portion of the basket


10


, are woven through the upsplints


30


and fill splints


38


, as shown in FIG.


15


. The short splint


34


closest to the front panel


12


and the lower rear panel


16


, namely, short splint


42


, is woven over the outer surface of the outermost upsplints


30


in the upper bottom panel


18


. The remaining short splints


34


are woven through the upsplints


30


and fill splints


38


in any desired pattern, with an alternating, over-and-under pattern being preferred. Outer reinforcements


62


may be positioned over the upsplints


30


and secured to the splints and inner reinforcements of the upper bottom panel


18


as described above.




After the upper bottom panel


18


has been formed, it is secured to the second segment


80


by a “hold-down” or clamp, shown in

FIGS. 22A through 22C

. Preferably, the conventional hold-down used to secure the lower bottom panel to the first segment


70


is removed and an L-shaped hold-down


90


, best shown in

FIGS. 16 and 22A

, is used to secure both the upper


18


and lower


14


bottom panels to the combined form


68


. The hold-down


90


defines parallel plates


92


,


94


that press the upper


18


and lower


14


bottom panels, respectively, against the form


68


. The plates


92


,


94


are connected by an arm


95


extending from plate


94


toward plate


92


, and a spacer


96


between arm


95


and plate


92


. A recess


98


(shown in

FIG. 22C

) may be provided in the upper surface


97


of the arm


95


for securing the hold-down


90


to a weaving horse. A weight block


99


may be provided on the arm


95


to control the rotation of the combined form


68


and hold-down assembly on the weaving horse.




The upsplints


30


and short splints


34


extending beyond the borders of the upper bottom panel


18


are bent and shaped around the second segment


80


, with the short splints


34


arranged substantially parallel to the cross splints


32


of the deep portion. An inner top band


52


may be secured by guides


78


provided along the bottom of the combined form


68


before construction of the remainder of the basket panels begins (shown in FIGS.


21


A and


21


B).

FIG. 17

shows an inner top band secured in this position by guides


78


.




Weave strips


36


are woven through the cross splints


32


and short splints


34


that collectively define the upper left


22


and right


24


panels and the upsplints


30


that define the front


12


and upper rear


20


panels. Any desired weave pattern may be used, with an alternating, over-and-under pattern being preferred. Successive rows of weave strips


36


are added until the panels reach a desired height. When weaving is complete, the ends of the splints


30


,


32


,


34


may be trimmed to a substantially uniform height that is slightly shorter than the desired height of the finished basket. The upper rim of the basket


10


is finished by securing the upper splint ends to a top band


50


, which may include an inner top band


52


and an outer top band


54


. When both inner


52


and outer


54


top bands are used, the splints


30


,


32


,


34


are sandwiched between the inner band


52


(which is held in position against the form by guides


78


along the bottom of the combined form


68


as shown in

FIG. 17

) and the outer band


54


. Preferably, the splints are secured to the band(s) with fasteners.




One or more handles may be secured to the basket if desired (best shown in FIGS.


5


and


6
