Description




FIELD OF THE INVENTION




The present invention relates to garment hangers.




BACKGROUND OF INVENTION




The prior art is replete with various configurations of garment hangers that incorporate structure for selectively adjusting the hanger's width to accommodate different size garments. Applicant's issued U.S. Pat. Nos. 5,102,019; 5,511,701, 5,664,710 and pending U.S. patent application Ser. No. 09/699,071 disclose some such structures as do certain ones of the references U.S. Pat. Nos. 2,477,873, 3,024,954, 5,044,535, European patents DE-C-286 192, WO-A-94 02056, DE-U-88 04 572 and DE-A-40 07 320 cited therein.




SUMMARY OF THE INVENTION




The present invention is directed to garment hangers incorporating improved structures for adjusting the hanger's width to support garments of different sizes.




According to one aspect of the present invention there is provided an adjustable garment hanger having first and second elongated support arms extending from a medial portion, a transfer mechanism located at the medial portion; and first and second movable arms mounted respectively for translation along the first and second support arms. The first and second support arms are supported relative to one another at an obtuse angle therebetween; and in that each of the movable arms couples to the transfer mechanism by a linkage tongue for reciprocal translation of the movable arms along their respective support arms. When force is applied on the first movable arm in the direction along the axis of the respective first support arm, the force is translated to the second extension arm for reciprocal motion of the second extension arm along the second support arm. The transfer mechanism incorporated in this embodiment is at least one wheel and in that each of the linkage tongues is coupled to the wheel for reciprocal translation of the movable arms along their respective support arms. Each of the linkage tongues is preferred to comprise a flexible section, located at the region proximate to the medial portion of the hanger.




In another alternative embodiment, an adjustment knob is integrally molded or coupled to the wheel to facilitate manual turning thereof for translation of the movable arms. Conveniently, an electric motor is provided for driving the wheel.




In yet a further embodiment a transfer mechanism preferably comprising at least a first wheel mounted proximal to the medial portion for rotation; each of the linkage tongues having an inner end and an outer end. The inner ends of each linkage tongue is coupled to the transfer mechanism for reciprocal translation of the movable arms along their support arms. Advantageously, in any of the embodiments the wheel(s) includes a plurality of peripherally defined teeth and each inner end of the linkage tongues defines a plurality of teeth. Although the linkage tongue is preferably to be of a rigid structure for this embodiment, it can also comprise a flexible region to interact with the adjustment or transfer mechanism.




According to another aspect of the present invention there is provided a method of forming an adjustable garment hanger, comprising the steps of arranging first and second elongate support arms to define an obtuse angle therebetween; providing an adjustment or transfer mechanism at the medial portion of the hanger; mounting open ended first and second linkage tongues on the first and second arms respectively for translation therealong; and for reciprocal translation of the linkage tongues along their respective support arms; mounting first and second movable arms to travel along the respective supporting arms; and connect each linkage tongues with the respective movable arms.




In yet another embodiment, the medial portion is divided into two halves; a front half and a rear half. The two supporting arms extend from each end of either the front half or the rear half of the medial portion, and these sections are formed as an integral part by injection molding or die-casting. The other half forms a cover to cover the medial portion only. In this embodiment, after the open-ended linkage tongues are installed in the first half of the hanger, the other half is covered onto the assembly to prevent the components from detached. In this design, each of the supporting arms is formed in a U shape channel to accommodate the linkage tongues of the two movable arms. Since the U shape channels are not covered, there is an opportunity for the remote ends of the linkage tongues to expose from the open sides of the U shape channels.




In a further preferred embodiment channels are provided for guiding each of the linkage tongues along a path that feed the linkage tongue to the adjustment or transfer mechanism located at the medial portion of the garment hanger. Conveniently, each of the channel or paths includes a first segment substantially aligned with one of the support arms and a second segment substantially aligned with the other of the support arms. The channels, or guides, preferable be able to guide the flexible linkage tongue along the respective supporting arm, have guiding walls surrounding the linkage tongue so as to maintain the flexible region of the linkage tongue to stay in a proper shape under control. In case of a U shape supporting arm design, a retaining structure is required to prevent the flexible linkage tongue from exiting the supporting arms through the open side of the U shape channel. One of the retaining design is to provide a guiding tongue or rib along the side of the first flexible linkage tongue and a matching groove along the side of the other flexible linkage tongue, such that the tongue and groove engage the two flexible linkage tongues together and prevent them from exiting the open side of the U shape supporting arm.




The gear of the upper linkage tongue is preferred to face upward and that of the lower linkage tongue to face downward, such that the matching tongue and groove design can be provided to the lower side of the upper linkage tongue and the upper side of the lower linkage tongue. Unlike applicant's previously invented adjustable hangers, the two flexible linkage tongues are touching and sliding along each other during the hanger width adjusting process. It means the tongue and groove of the two flexible linkage tongues are configured to slide against each other; accordingly it is difficult for the transfer mechanism to provide a gear in between the two linkage tongues. In a preferred embodiment, the transfer mechanism provides a first gear on top of the upper linkage tongue, a second gear beneath the lower linkage tongue. A third gear is positioned by the side of the sliding linkage tongues, engaging the first and second gears to provide the reciprocal transfer motion. Alternately an O ring with internal gears is provided for linking the first gear to the second gear to provide the reciprocal transfer motion.




In order to prevent the movable arms and the linkage tongues to be removed from the garment hanger when the movable arms are stretched to the outermost position, stoppers interacting between the linkage tongues and the guiding walls or a stopping structure at the medial portion are provided. Alternatively, interacting stopper can be provided in between the support arms and the moving arms as disclosed in applicant's issued U.S. Pat. No. 5,727,718. Many different stopper designs known to the art can be implemented to restrict the movement of the linkage tongues or the movable arms when they are extended to a predefined extended position.

DESCRIPTION OF THE PREFERRED EMBODIMENTS





FIG. 1

is a see through front view illustrating a preferred adjustable hanger embodiment


100


in accordance with the present invention. The hanger


100


includes a medial portion


105


connected to a pair of elongate supporting members and a suspension member


101


in the shape of a hook. The supporting arms arranged to define an obtuse angle from the medial portion


105


. On top of each supporting arms are the movable arms


103


and


107


that reciprocally slide along the supporting arms extended from the medial portion. The movable arm


107


is connected to a flexible linkage tongue


110


. Another flexible linkage tongue


104


extends from the inner end of the movable arm


103


. Each of the flexible linkage tongues are provided with a plurality of teeth (partially shown in

FIG. 1

) for engaging to the transfer mechanism. The proximal regions of the linkage tongues


104


and


106


are guided to engage an adjustment or transfer mechanism. In a preferred embodiment this adjustment mechanism is represented by one or more wheels rotatably mounted at the medial portion


105


of the garment hanger frame. The transfer mechanism may be connected to an adjustable knob


103


for adjusting the width of the hanger. The flexible proximal regions of the linkage tongue follow respective guide paths or channels that are tangent to the transfer mechanism. These guiding channels are substantially parallel to the supporting arms.




Thus, each linkage tongues


104


,


106


; and therefore the movable arms


103


,


107


can be reciprocally translated along its respective supporting arm according to the function of the transfer mechanism. Movement of the linkage tongues


104


,


106


, and the respective movable arms they connected can be accomplished by holding each movable arm in one hand and urging them inward or outward. Alternatively, the garment hanger can be held in one hand and either one of the movable arms urged inward or outward with the other hand. Engagement of the flexible region


104


with the transfer mechanism insures that any change in the spacing of one linkage tongue or movable arm from the medial portion is accompanied by an equal change in the spacing of the other linkage tongue


106


and movable arm


107


, i.e., the linkage tongues


104


,


106


are reciprocally and oppositely translated on their respective supporting arms. In another preferred embodiment, an adjustment knob is coupled to the transfer mechanism allows the user to adjust the width of the hanger while a garment is supported on the hanger.




A characteristic of the adjustable garment hanger of

FIG. 1

when compared with the prior art is that the two linkage tongues are sliding directly against each other. The transfer mechanism is coupled to the top side of the upper linkage tongue and the bottom side of the lower linkage tongue. In a preferred embodiment, on top of the upper linkage tongue


104


is a first wheel or gear


108


. Beneath the lower linkage tongue


106


is a second wheel or gear


110


. A third gear


109


engages in between the first gear


108


and the second gear


110


to form a reciprocal transfer mechanism.




A hanger


100


is, therefore, provided which can be quickly and easily adjusted to a lateral spacing between movable arms that most effectively supports a chosen garment. The movable arms are simply urged inward or outward by hand or an adjustment knob as necessary to best fit and support the garment and they remain in the desired spacing until readjusted for another garment. The hanger can be fabricated with an obtuse angle, between the movable arms


103


,


107


, that best accommodates and supports a chosen garment type, e.g., coats.




Directing attention now to a more detailed disclosure of the preferred embodiment relative to

FIG. 2A

, a view showing the section B—B of FIG.


1


. It is seen that upper first gear


108


is coupled to the upper teeth rack of the upper linkage tongue


104


; the second gear


110


is coupled to the bottom side of the lower linkage tongue


106


as illustrated in

FIG. 2C. A

third gear


109


, positioned by the side of the two sliding linkage tongues


104


and


106


, linked the first gear


108


to the second gear


110


to provide the reciprocal transfer motion as shown in FIG.

FIG. 3

illustrates the sectional view A—A of the supporting arm and movable arm. The outer portion


301


of the sectional view represents the movable arm which is adjusted against the inner supporting arm


303


. In order to save manufacturing cost, the supporting arm


303


is formed as a single piece structure as compared with a two halves structure illustrated by the prior art. In a preferred embodiment, the supporting arm


303


is structured to provide a upper wall


304


, a lower wall


308


and a side wall


302


. On the other side of the side wall


302


is an open space


310


to facilitate the injection process that forms the supporting arm


303


. In side the channel of the supporting arm


303


are the first linkage tongue


305


and the second linkage tongue


306


that are in direct contact and slide against each other. The channel formed by the three walls


304


,


302


and


308


governs the movement of the two linkage tongues. In order to prevent the linkage tongues from leaving the guiding channel through the open space


310


, the upper linkage tongue


305


is coupled to the lower linkage tongue


306


with a guiding tongue


321


and glove


322


design.





FIG. 4

illustrates the exploded view of an alternate preferred embodiment. The difference of this embodiment as compared with that of the first preferred embodiment of

FIG. 1

is that the third engagement gear


109


of

FIG. 1

is replaced by an O ring shaped gear


404


. The internal gear of the O ring linked the first gear


405


to the second gear


406


. All other designs are substantially similar to that of FIG.


1


. It can be observed that the linkage tongue


423


extends from the inner end of the movable arm


421


. The linkage tongue


424


extends from the inner end of the second movable arm


422


. Both supporting arms


412


and


412


provide a U shaped channel to accommodate the linkage tongues


423


and


424


that slide directly against each other. During the assembly process the movable arms


421


and


422


are assembled into the supporting arms


411


and


412


, with the tongue and groove of the two linkage tongues


423


and


424


engaged. The upper surface of the linkage tongue


424


and the lower surface of the linkage tongue


423


define a plurality of spaced teeth. The gears


405


and


406


are placed onto the upper and lower sides of the linkage tongues, and rotate at the shafts


413


. The third gear


109


as illustrated in

FIG. 1

, or the O shaped gear ring


404


is then assembled to link the first gear


405


to the second gear


406


. After placing the suspension member


401


and the second hook


403


into the medial portion, the housing cover


402


is provided to complete the adjustment hanger assembly.
