Description




FIELD OF THE INVENTION




The invention relates to a toy knitting machine, and in particular to a toy knitting machine of the type that is operable by manually rotating a portion of the toy knitting machine to actuate a knitting mechanism within the machine for creating a knitted strand.




BACKGROUND OF THE INVENTION




Toy knitting machines have been previously designed. One known machine is produced by Tomy Company Ltd. of Japan. This machine utilizes a hand operated crank to rotate a knitting mechanism that is mounted within a housing to create a knitted product. The entire knitting mechanism is separate from the housing thereby requiring that the knitting mechanism be assembled into the housing in a relatively complicated assembly process requiring a relatively large number of assembly steps. Another known knitting machine is produced by the Bandai Company of Japan. The Bandai machine includes a knitting mechanism that is assembled into a housing, with a portion of the housing being rotatable to actuate the knitting mechanism. Like the Tomy machine, the entire knitting mechanism of the Bandai machine must be assembled into the housing in a complicated assembly process.




The knitting mechanisms in the Tomy and Bandai machines are each separate from the machine housings and the components of the knitting mechanisms must be assembled into the housings. In the case of the Tomy machine, the majority of the knitting mechanism is first assembled into a subassembly which must then be positioned into the housing. However, upon positioning within the housing, the subassembly can potentially be located incorrectly, resulting in an incorrect assembly of the machine. The construction of the Bandai machine requires that each individual component of the knitting mechanism must be assembled into the housing, which can result in an incorrect assembly if the components are not positioned correctly within the housing.




Furthermore, the housings of the Tomy and Bandai machines each include a lower housing portion that encloses substantially the entire knitting mechanism and a transparent upper housing portion that is detachably fitted onto the lower housing portion to enable viewing of the knitting mechanism during operation. The upper housing portion, when fitted to the lower housing portion, serves to trap and guide the yarn during knitting. Since the upper housing portion is detachable, it can easily become lost or misplaced, meaning that it can no longer trap and guide the yarn, thereby rendering the machine useless.




What is needed is an improved toy knitting machine that resolves these and other deficiencies of conventional toy knitting machines, as well as providing many added benefits and features not found in conventional toy knitting machines.




SUMMARY OF THE INVENTION




The invention provides an improved toy knitting machine, particularly a toy knitting machine of the type that is operable by manually rotating a portion of the toy knitting machine to actuate a knitting mechanism within the machine. The toy knitting machine is designed to make assembly easier and more efficient by reducing the number of assembly steps and preventing incorrect assembly of the machine. In addition, the components of the knitting machine are optimally positioned upon assembly to produce an improved knitted product. Furthermore, the toy knitting machine is designed to prevent inadvertent loss of the upper housing portion.




In one embodiment in accordance with the principles of the invention, a toy knitting machine is provided which includes a lower housing and an upper housing pivotally connected to the lower housing which contains a knitting mechanism positioned therein. The upper housing is pivotable relative to the lower housing between a first position at which the upper housing substantially covers the knitting mechanism preventing access thereto, and a second position at which the upper housing does not cover the knitting mechanism thereby permitting access to the knitting mechanism. By pivotally connecting the upper housing to the lower housing, misplacement and loss of the upper housing is prevented.




In accordance with another embodiment of the invention, a toy knitting machine is provided which includes a lower housing having a knitting mechanism positioned therein. The knitting mechanism including a plurality of knitting stitches and a knitting stitch guide track is engaged with the knitting stitches for actuating the knitting stitches. The knitting stitch guide track includes a lower guide track portion and an upper guide track portion, with the lower guide track portion being a one piece construction with the lower housing. In addition, an upper housing is engageable with the lower housing, where the knitting stitches are covered by the upper housing when the upper housing is engaged with the lower housing.




Since the lower guide track portion is a one-piece construction with the lower housing, assembly of the machine is facilitated since the position of the lower guide track relative to the lower housing is prefixed and the positioning of other elements, such as the upper guide track portion, can then be reliably and easily performed based upon the pre-positioning of the lower guide track. Furthermore, accurate positioning of the guide track within the lower housing is reliably obtained as the integral lower guide track portion determines the position of the entire guide track.




A variety of additional advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. The advantages of the invention will be realized and attained by means of the elements and combinations particularly pointed out in the claims. It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory only and are not restrictive of the invention as claimed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT




The invention relates to a toy knitting machine having a lower housing containing a knitting mechanism capable of performing a knitting operation. An upper housing is pivotally connected to the lower housing for selectively covering and uncovering the knitting mechanism thereby controlling access to the knitting mechanism. By connecting the upper housing to the lower housing with a pivot, loss of the upper housing, which would disable operation of the knitting machine, is prevented.




The invention further provides a toy knitting machine having a lower housing containing a knitting mechanism capable of performing a knitting operation therein. The knitting mechanism includes a plurality of knitting stitches and a knitting stitch guide track engaged with the knitting stitches for actuating the knitting stitches during a knitting operation. The knitting stitch guide track includes a lower guide track portion and an upper guide track portion, with the lower guide track portion being a one piece construction with the lower housing. The machine further includes an upper housing that is engageable with the lower housing for selectively covering and uncovering the knitting mechanism. This construction provides a compact machine in which the knitting mechanism is entirely contained within the upper and lower housings. Furthermore, since the lower guide track portion is a one-piece construction with the lower housing (i.e. integrally formed with the lower housing), assembly of the machine is facilitated and the guide track is always positioned in the optimal position relative to the lower housing upon assembly.




With reference now to the figures, one implementation of the toy knitting machine is illustrated, with the toy knitting machine being referenced generally by the reference numeral


10


.

FIGS. 9A-D

show the knitting machine


10


in its assembled state and illustrate how to use the machine


10


, with

FIG. 1

providing an exploded perspective view of the elements that when properly assembled, form the machine


10


.




Referring initially to

FIG. 1

, it is seen that the machine


10


includes a lower housing


12


and an upper housing


14


that is adapted to be pivotally connected to the lower housing for pivoting movements relative thereto between a first, covering position (shown in

FIGS. 9C

,


9


D) and a second, open position (shown in FIG.


9


A). The lower housing


12


has a generally ring-shaped outer wall


16


having a first end


18


and a second end


20


, with the diameter of the outer wall


16


being constantly tapered from the first end


18


to the second end


20


such that the outer wall


16


forms a portion of an oval. The lower housing


12


further includes a discharge hole


21


through the bottom thereof at the second end


20


through which the knitted product exits.




The upper housing


14


includes an outer wall


22


forming generally one-half of a hollow oval shape, with the diameter of the wall


22


constantly decreasing from a first end


24


to a second end


26


. Thus, when the upper housing


14


is in its first, covering position relative to the lower housing


12


, as seen in

FIGS. 9C-D

, the outer wall


16


of the lower housing


12


and the outer wall


22


of the upper housing


14


combine to form a substantial portion of an egg shape, thereby giving the machine


10


an egg-shaped appearance.




A pivot post


28


is disposed on the outer wall


16


at the first end


18


, and a pair of pivot ears


30


are disposed at the end


24


of the outer wall


22


on either side of a notch


32


provided in the outer wall


22


. The distance between the pivot ears


30


, and thus the length of the notch


32


at the end


24


, is slightly greater than the length of the pivot post


28


such that the pivot ears


30


are disposable on each side of the pivot post


28


. An axle


34


is then inserted into aligned passages formed through the pivot post


28


and the pivot ears


30


thereby pivotally connecting the lower housing


12


and the upper housing


14


.




The notch


32


in the outer wall


22


includes a tapered section


36


that receives therein an element (described below) mounted on the lower housing


12


when the upper housing


14


is pivoted to the first, covering position, and a rounded section


38


disposed at the end of the tapering section


36


. The element that is received in the tapered section


36


cooperates with the rounded section


38


to define a yarn inlet passage


40


to enable passage of a yarn strand


42


through the upper housing


14


and into the interior of the machine


10


as shown in FIG.


9


D.




As best seen in

FIGS. 9A and 9B

, a knitting mechanism


50


is positioned within the lower housing


12


for performing a knitting operation on the yarn strand


42


to produce a knitted strand


52


. The knitting mechanism


50


includes a plurality of rotatable and stationary elements that are mounted on and/or within the lower housing


12


.




With reference to

FIGS. 1

,


2


A and


2


B, the knitting mechanism


50


includes a lower guide track portion


54


that is integrally formed with, i.e. is a one-piece construction with, the lower housing


12


surrounding the discharge hole


21


, and projects upwardly in the interior of the housing


12


. The track portion


54


is generally circular in construction and has an upper surface thereof


56


that defines the lower part of a knitting stitch guide track


57


, described more fully later in the description. As best seen in

FIGS. 1 and 2B

, the track portion


54


has an apex or highest point


58


, as well as a nadir or lowest point


60


(not visible in

FIG. 1

) located generally diametrically opposite of the apex


58


.




With reference to

FIGS. 1 and 7

, the knitting mechanism


50


further includes a stationary stitch track cover


62


that is connected to the lower housing


12


and includes an upper guide track portion or wall


64


with a bottom surface that is spaced from and faces the upper surface


56


of the lower guide track portion


54


when the cover


62


is mounted on the lower housing


12


to define the aforementioned knitting stitch guide track


57


. Like the track portion


54


, the track portion


64


is generally circular to define a passage having a diameter generally equal to the diameter of the discharge hole


21


, and has an apex or highest point


66


that cooperates with the nadir


60


on the track portion


54


to define the nadir of the guide track


57


. The track portion


64


further includes a nadir or lowest point


68


that cooperates with the apex


58


on the track portion


54


to define the apex of the guide track


57


.




The cover


62


further includes a generally circular ring portion


70


from which the track portion


64


extends. The lower housing


12


includes three equally spaced posts


72




a,




72




b,




72




c


that extend upwardly from the base of the housing


12


between the track portion


54


and the outer wall


16


, with the posts


72




a-c


projecting above the first end


18


. The lower housing


12


further includes a plurality of shoulders


74


positioned on the interior surface of the wall


16


at a predetermined distance below the first end


18


. The outer diameter of the ring portion


70


is slightly less than the diameter of the outer wall


16


at the first end


18


such that the ring portion


70


can fit within the lower housing


12


, with the ring portion


70


engaging the shoulders


74


to define its fully inserted position. Furthermore, the ring portion


70


is provided with three equally spaced holes


76




a,




76




b,




76




c


therethrough to allow free passage of the posts


72




a-c.


Thus, when the cover


62


is properly positioned, the ring portion


70


engages the shoulders


74


, with the posts


72




a-c


passing through the holes


76




a-c,


and the track portion


64


is spaced vertically above the track portion


54


to define the guide track


57


therebetween.




The knitting mechanism


50


also includes a rotatable stitch barrel


78


that is sized for rotatable disposition within the passages defined by, and to be closely surrounded by, the lower and upper track portions


54


,


64


. Referring to

FIGS. 1

,


3


A and


3


B, the stitch barrel


78


includes a central cylinder


80


defining a central passage


82


through which the knitted strand


52


is discharged. A plurality of circumferentially spaced v-shaped pairs of ribs


84


are connected to the outer surface of the cylinder


80


and define therebetween a plurality of, preferably six, stitch guide slots


86


. A ring


88


having a diameter slightly larger than the radius of the barrel


78


defined by the ribs


84


interconnects the bases of the ribs


84


and is designed to engage with a circular shoulder


90


(seen in

FIG. 7

) defined on the lower housing


12


when the barrel


78


is fully inserted. Openings


91


are formed between the ring


88


, the cylinder


80


and the ribs


84


defining each slot


86


, the purpose of which will be later described.




In addition, a pair of posts


92




a,




92




b


are disposed in diametrically opposite pairs of ribs


84


and project slightly above and below the cylinder


80


, and each projecting post is provided with a threaded bore


94


for receiving screws used to assemble the machine


10


, as will be described later in the description.




Alternatively, as shown in

FIG. 3C

, the ring


88


′ of the stitch barrel


78


′ is made discontinuous, whereby the ring


88


′ is composed of a plurality of ring portions interconnecting the ribs


84


and leaving the slots


86


open. This construction improves the sliding movements of the knitting stitches (described below) within the slots


86


.




Slidably disposed within each of the guide slots


86


for vertical movements therein, and forming an additional part of the knitting mechanism


50


, are a plurality of knitting stitches


96


. In the illustrated embodiment, there are six guide slots


86


and therefore six knitting stitches


96


. However, it is to be realized that a larger or smaller number of guide slots and knitting stitches could be used if desired. The knitting stitches


96


, shown in

FIGS. 1 and 8A

, are identical to each other with each stitch


96


being generally elongated and including a base end


98


and a hook end


100


. The stitches


96


are shaped to enable up and down vertical sliding movements thereof within the respective guide slots


86


, with the base end


98


of each stitch


96


being generally rectangular in shape and the intermediate portion of each stitch between the hook end


100


and base end


98


being generally T-shaped. The hook end


100


of each stitch


96


is provided with a hook that engages the yam strand


42


during a knitting operation to knit the strand into a knitted strand


52


.




Each stitch


96


further includes a cam projection


102


on the base end


98


thereof that in use is disposed in the stationary guide track


57


such that upon rotation of the stitch barrel


78


, the cam projection


102


rides in the guide track


57


which causes the stitch


96


to be actuated up and down within its respective guide slot


86


. The stitches


96


are oriented so that the cam projections


102


and the hooks face outwardly. During rotation of the barrel


78


, which causes the stitches


96


to move vertically up and down due to the shape of the guide track


57


, the base ends of the stitches


96


move down into the openings


91


when the cam projection


102


of the respective stitch is at the nadir of the guide track


57


, thereby enabling a full range of vertical movement of the stitches.




A ring shaped lower stitch barrel cover


104


is fastened to the bottom of the stitch barrel


78


and acts as the actuator for causing rotation of the stitch barrel


78


. As shown in

FIGS. 9A

,


9


C and


9


D, the cover


104


is shaped so as to cooperate with the shape of the lower housing


12


to complete the overall egg-shape of the machine


10


. Returning to

FIG. 1

, the cover


104


has a through passage


106


with a diameter substantially equal to the diameter of the central passage


82


of the barrel


78


to allow passage of the knitted strand


52


therethrough. The cover


104


is further provided with a pair of through holes


108




a,




108




b


through which screws


110


or the like extend for engagement with the threaded bores


94


in the projecting posts


92




a,




92




b,


respectively, at the bottom of the barrel


78


so as to enable securement of the cover


104


to the bottom of the barrel


78


.




Secured to the opposite end of the barrel


78


is a ring shaped, upper stitch barrel cover


112


. The cover


112


, shown in detail in

FIGS. 1

,


4


A and


4


B, includes a central passage


114


having a diameter approximately equal to the diameter of the central passage


82


of the barrel


78


to allow passage of yarn therethrough. Around the periphery of the cover


112


is a plurality of equally spaced T-shaped passages


116


extending through the cover


112


which allow passage of the knitting stitches


96


through the cover


112


as well as guiding and stabilizing the stitches


96


during their up and down vertical movements. A pair of yarn guide posts


118


associated with each T-shaped passage


116


extend vertically on the sides of the respective passage


116


, with the yarn being looped around the guide posts during the knitting operation. The cover


112


further includes a pair of diametrically opposite holes


117




a,




117




b


therein through which screws


119


extend into threaded engagement with the with the threaded bores


94


in the projecting posts


92




a,




92




b,


respectively, at the top of the barrel


78


so as to enable securement of the cover


112


to the top of the barrel


78


.




The cover


112


further includes ratchet teeth


120


about the bottom periphery thereof forming a part of a one-way rotation mechanism for permitting rotation of the stitch barrel


78


only in a counterclockwise direction as shown by the arrows in

FIG. 9C. A

pawl


122


is pivotally mounted on a pin


124


provided on the ring portion


70


of the cover


62


, with one end


126


of the pawl


122


engaging the ratchet teeth


120


in the event that the barrel


78


and the cover


112


connected thereto are rotated in the clockwise direction. The opposite end


128


of the pawl


122


engages a stop


130


formed on the ring portion


70


to maintain the end


126


in position to prevent clockwise rotation.




The outer diameter of the cover


112


is also sized such that the cover


112


rests on the top surface of the ring portion


70


of the cover


62


when the cover


112


is connected to the barrel


78


, thereby preventing the assembly of the cover


104


, the barrel


78


, and the cover


112


from falling out the bottom of the machine


10


.




With reference to

FIGS. 1 and 5

, a yarn divider ring


132


is also provided which rotates with the cover


112


for separating the hooks on each knitting stitch as well as separating the yarn engaged by each hook. The ring


132


has an outer wall


134


that surrounds the top portion of the cover


112


, including the T-shaped passages


116


and vertical posts


118


, as a bottom surface of the wall


134


is positioned slightly above the top surfaces of the ratchet teeth


120


. On the interior surface of the wall


134


a plurality of equally spaced divider plates


136


are disposed, with the plates


136


having mounting portions


138


that is adapted to fit within a respective groove


140


formed in the cover


112


, thereby mounting the divider ring


132


on the cover


112


and preventing relative rotation therebetween.




Turning to

FIGS. 6A and 6B

, along with

FIG. 1

, a yarn threading cap


142


is provided for guiding the yarn strand


42


that enters through the inlet passage


40


to the knitting stitches


96


and providing tension to the strand


42


. The cap


142


is a circular ring formed by a top wall


144


and a side wall


146


that when mounted surrounds the cover


112


and the divider ring


132


. Three generally hollow mounting posts


148




a


,


148




b


,


148




c


are disposed inside of the side wall


146


at locations corresponding to the locations of the posts


72




a-c


so that the tops of the posts


72




a-c


extending above the surface of the ring portion


70


are received in the posts


148




a-c.


Holes


150


extend through the top wall


144


and through the posts


148




a-c


to allow passage of screws


152


which thread into threaded holes


154


in the posts


72




a-c


to permit securement of the cap


142


to the lower housing


12


.




Disposed on the backside of the side wall


146


of the cap


142


is a tapered element


156


having a shape corresponding to the tapered section


36


of the notch


32


in the upper housing


14


, such that when the upper housing


14


is in the covering position, the element


156


fills the tapered section


36


of the notch


32


, leaving only the rounded section


38


through which the yarn strand


42


can pass. Positioned on top of the tapered element


156


is a pair of projections


158


defining a slot


160


through which the strand


42


passes. A further pair of projections


162


are disposed on the top wall


144


slightly downstream from the projections


158


, with the projections


162


defining a second slot


164


through which the strand


42


passes.




One of the most important aspects of the knitting machine


10


concerns the positioning of the apex of the guide track


57


. If the apex is not properly located, the knitting operation is adversely affected. The inventors have discovered that the apex


58


of the track portion


54


, and thus the apex of the guide track


57


itself, should be located closely downstream from the point at which the yarn strand enters the machine


10


in order to provide an improved knitting operation. More particularly, as shown in

FIG. 2A

, the apex


58


should be located at an angle (x from the point at which the strand enters the machine


10


, with the angle ox preferably being between about 20 degrees to about 30 degrees, and more preferably about 23.5 degrees.




As described previously, the lower guide track portion


54


is a one-piece construction with the lower housing


12


. Therefore, the position of the apex


58


is predetermined by the manufacturing of the lower housing


12


and accurate positioning of the apex of the resultant guide track


57


is always achieved. Thus by making the track portion


54


integral with the lower housing


12


, inaccurate positioning of the guide track apex due to assembly error is eliminated.




Referring now to

FIG. 8A

, assembly of the knitting machine


10


will now be described. Starting with the lower housing


12


, the stitch barrel


78


is first inserted into the lower housing as shown by the arrow


170


until the ring


88


abuts the shoulder


90


. The knitting stitches


96


are then loaded into the guide slots


86


of the stitch barrel


78


, shown by arrow


172


, such that the cam projections


102


rest on the top surface


56


of the lower track portion


54


. Subsequently, the stitch track cover


62


is positioned, shown by arrow


174


, with the guide track portion


64


thereof forming with the lower guide track portion


54


the guide track


57


, and with the posts


72




a-c


extending through the holes in the ring portion


70


such that they project above the ring portion


70


. The upper stitch barrel cover


112


is then positioned, as shown by arrow


176


, and secured to the barrel


78


by the screws


119


. The lower stitch barrel cover


104


can also be secured at this time, or the cover


104


could be initially secured to the barrel


78


prior to inserting the barrel into the lower housing


12


. Thus in four steps, a main subassembly


177


is created in which the knitting mechanism


50


is completely assembled into the lower housing


12


.




Once the main subassembly


177


is created, and as shown in

FIG. 8B

, the pawl


122


is mounted as shown by arrow


180


, the yarn divider ring


132


is then positioned on the cover


112


(arrow


182


), and the yarn threading cap


142


is secured to the lower housing


12


(arrow


184


) using the screws


152


. Thereafter, the upper housing


14


is placed in position (arrow


186


) and secured to the lower housing


12


by the axle


34


(arrow


188


). Of course, it is to be realized that the components could be assembled in other orders as well. For instance, the upper housing


14


could be secured to the lower housing


12


at any point during assembly, including prior to forming the main subassembly.




The use and operation of the knitting machine


10


will now be described with reference to

FIGS. 9A-D

. It is assumed that the machine


10


is fully assembled and ready for use. As shown in

FIG. 9A

, the upper housing


14


is pivoted to the open position, and the yarn strand


42


is passed through the notch


32


and dropped down through the center of the machine


10


until a predetermined length of yarn, such as about 4-5 cm, extend below the machine.




The yarn is then placed around the hooks on the knitting stitches


96


as shown in

FIG. 9B

, and the yarn is passed through the slots


160


,


164


as illustrated. During this step, it is important to make sure that the yarn is in front of the hook on a knitting stitch


96


and then behind the next hook on the adjacent knitting stitch, this pattern being repeated for all the knitting stitches


96


.




One the yarn has been properly threaded, the upper housing


14


is closed while ensuring that the yarn remains in position through the slots


160


,


164


, and knitting can commence. Knitting is started by holding the lower housing


12


and rotating the lower barrel cover


104


in a counter-clockwise direction as shown by the arrows in FIG.


9


C. Rotation of the cover


104


causes rotation of the barrel


78


and the knitting stitches


96


. The cam projections


102


on the stitches


96


ride in the guide track


57


, thereby causing the stitches


96


to move vertically upward and downward due to the shape of the guide track


57


. The yarn is engaged by the hooks on the ends of the knitting stitches


96


which knit the yarn into the knitted strand


52


. After rotating the cover a number of times, such as 5-8 times, it is important to pull down on the end of the yarn strand to prevent the machine from getting stuck with yarn.




Once the desired length of knitted strand


52


is produced, the yarn is cut as shown in

FIG. 9D

a distance from the hole


40


, such as 20 cm, and the lower cover


104


is rotated until the remaining length of yarn has exited the machine


10


.




To render the machine


10


more aesthetically appealing, particularly to children, the machine


10


can be provided with features so that the machine simulates a figurine or character. For instance, with reference to FIGS.


1


and


9


C-D, simulated hair


200


, or the like, can be affixed to the upper housing


14


via a pin


202


. Other features, such as eyes, a nose and a mouth can be integrally formed on, or affixed to, the upper housing, such that the upper housing


14


essentially simulates the head of a character. To complete the character, clothing, arms, etc. can be disposed on the lower housing


12


so as to simulate the body of the character. FIGS.


1


and


9


A-D further show feet


204


that can be attached to the cover


104


via the screws


110


, thereby simulating the feet of the character. In addition to enabling the simulated character to stand, the feet


204


provide a convenient handle to grasp to aid in rotating the lower cover


104


during the knitting operation.




All the components of the machine


10


, except for the screws and the axle, are preferably made from molded plastic, although other materials, including metal, could be used.
