Description
- This application claims the benefit of U.S. Provisional Application Ser. No. 60/517,771 filed Nov. 4, 2003, which is hereby incorporated by reference in its entirety.
- This invention relates generally to wheeled baggage items having towing handles for rolling the baggage along the ground, and more particularly, to retractable towing handles for wheeled baggage.
- Various types of bags, from luggage items to briefcases and backpacks, now include wheels and a towing handle which allow the bags to be pulled along a surface rather than being carried above the ground. The towing handle is typically located on an end of the bag opposite the wheels, and the bag is pulled along the ground in an inclined position. Such handles can be very convenient and are now popular.
- Typically, the towing handle is mounted to telescoping supports extending alongside a back panel of the bag, and the handle is extendible for towing or retractable into the bag in a generally flush position with an outer contour of the bag. Conventionally, the handles were rigidly mounted to the supports and when the supports were extended, the handle was in a fixed position relative to the supports. It has been found, however, that such handles can become uncomfortable to hold for an extended period of time. This is at least in part because a significant portion of the weight of the bag is supported by the user gripping the handle.
- Various types of handle systems have been developed to reduce user fatigue in towing baggage. For example, pivoting or rotatable handles have been employed in an effort provide more comfortable pulling positions. While known handle systems have had varying degrees of success in addressing these issues, many of them tend to be quite complicated, expensive to implement, and not as reliable as desired.
- Also, many known towing handle systems are positioned in-line with the telescoping supports in use, and therefore are positioned over the center of the bag as it is being towed. In such a position it is likely that the bag may undesirably strike the heel of the person towing it and interrupt the gait of the person.
- It would be desirable to provide a towing handle for wheeled baggage which overcomes these and other disadvantages.
- According to an exemplary embodiment, a towing handle system for wheeled baggage is provided. The handle system comprises first and second support posts, and a towing handle positionable between an upright position parallel to the support posts and a towing position at an angle with respect to the support posts. The towing handle comprises a locking latch mechanism comprising an angle position element extending between the first and second posts, and the angle position element has a ribbed outer surface. A locking element comprises an inner surface received over the outer surface of the angle position element, and the inner surface lockingly engages the angle position element in a first orientation corresponding to the upright position and lockingly engages the angle position element in a second orientation defining the towing position.
- Optionally, the towing position is oriented at substantially a 45° angle from the upright position, and a biasing element urges the locking element to one of a locked and unlocked position. A shell and a push button coupled to the shell may be provided, and the push button unlocks the locking element from the angle position element.
- According to another exemplary embodiment, a baggage piece is provided. The baggage piece comprises a body comprising at least one body panel and a pair of wheels. First and second telescoping support posts are coupled to the body, and a retractable towing handle is positionable between an upright position parallel to the support posts and a towing position at an angle with respect to the support posts. The handle extends away from the body panel in the towing position, and the towing handle comprises a handle shell and a locking latch mechanism mounted to the shell. The locking latch mechanism comprises an angle position element mounted stationary to one of the shell and the supports, and the angle position element extends between the first and second posts and comprises a first engagement surface. At least one locking element is mounted stationary to the other of the shell and supports, and the locking element comprises a second engagement surface received over the first engagement surface of the angle position element. The second engagement surface lockingly engages the locking element in a first orientation corresponding to the upright position and lockingly engages the locking element in a second orientation defining the towing position.
- According to another exemplary embodiment, a piece of baggage is provided. The baggage comprises a body defining a compartment for stowing an item for transport, wheels attached to the body, first and second telescoping support posts mounted to the body, and a towing handle system. The towing handle system comprises a U-shaped handle shell pivotally mounted to the first and second support posts, a push button coupled to the shell, first and second rocker arms pivotally mounted to the shell and responsive to movement of the push button, and first and second release cables coupled to the respective first and second rocker arms. A locking latch mechanism is coupled to the release cables and extends transversely between the first and second support posts at a distal end of the U-shaped handle, and the locking latch mechanism comprises an angle position element having a ribbed engagement surface, and a locking element comprising a grooved engagement surface received over the ribbed engagement surface of the angle position element. The grooved engagement surface lockingly engages the locking element in an upright position and lockingly engages the locking element in a towing position wherein the handle shell is angled with respect the support posts.
- In another embodiment, a handle assembly for a towable bag is provided. The handle assembly comprises a U-shaped shell and a locking latch mechanism mounted to the U-shaped shell. The locking latch mechanism comprises a shaft mounted stationary to the shell and at least one rib extending from an outer surface of the shaft. A pair of locking elements are slidably mounted to the shaft and movable along an axis of the shaft between locked and unlocked positions. The locking elements move in opposite directions from one another and the rib is located between the locking elements in each of the locked and unlocked positions.
- In still another embodiment, a handle assembly for a towable bag is provided. The handle assembly comprises a U-shaped shell, and a locking latch mechanism mounted to the U-shaped shell. The locking latch mechanism comprises a position selector and locking plate, and the position selector and the locking plate comprise engagement surfaces which mesh to position the shell relative to the locking plate. The position selector moves beneath the locking plate in an unlocked position.

FIG. 1 is perspective view of awheeled bag 100 including a retractabletowing handle system 102 formed in accordance with an exemplary embodiment of the invention. Thebag 100 includes a body fabricated from known materials and having aback panel 104,side panels bottom panels front panel 114. Thebody panels -
Wheels 116 are mounted to the lower end of thebag 100 in a known manner. While in the illustrated embodiment thebag 100 is a general purpose luggage bag, in alternative embodiments other types of wheeled bags may be employed, including but not limited to wheeled brief cases, duffel bags and the like as those in the art will appreciate. InFIG. 1 , the towinghandle system 102 is positioned within arecess 118 in the top andback panels -
FIG. 2 illustrates a portion of thebag 100 with thetowing handle system 102 in an extended position. Thetowing handle system 102 includes a pair of telescoping support posts orpoles 120 and ahandle assembly 122 coupled to an end on the support posts 120. The support posts 120 extend generally alongside theback panel 104, and are fixedly mounted to thebag 100 within therecess 118. In accordance with known telescoping supports, the support posts 120 include sliding support members arranged in a concentric fashion, and the sliding members include spring loaded pins (not shown) which engage apertures (not shown) to lock the supports in an extended position (FIG. 2 ) and a retracted position (FIG. 1 ). Thehandle assembly 122 includes apush button 124 which, among other things, releases the pins from the apertures in theposts 120 and allows theposts 120 to telescope to the extended or retracted positions. The support posts 120 may be fabricated from, for example, aluminum, according to a known process. - As illustrated in
FIG. 3 , thepushbutton 124 also releases a locking latch mechanism (not shown inFIG. 3 ) which allows thehandle assembly 122 to move between an upright position (shown in phantom inFIG. 4 ) substantially parallel to the support posts 120, and a towing position at a predetermined angle α with respect to the axis of the support posts 120. Thus, in the towing position, thehandle assembly 122 leans at the angle α with respect to the bag, and further, thehandle assembly 122 leans in a direction away from anaxis 130 of thebag 100 and extends away from and beyond theback panel 104 of thebag 100. -
FIG. 4 illustrates thebag 100 in a towing position with thebag 100 inclined on asupport surface 140 such as a floor and with thewheels 116 in rolling contact with thesupport surface 140. In such a position, a user may grip thehandle assembly 122 to tow thebag 100 in a direction of arrow A with thewheels 116 rolling on thesupport surface 140. Because thehandle assembly 122 is leaned at the predetermined angle α in the towing position, an angle of inclination β of thebag 100 with respect to thesupport surface 140 is greater than it would otherwise be if the handle assembly were located in the upright position (FIGS. 2 and 3 ). The increased angle of inclination β places the bag in more of an upright position as it is towed in the direction of arrow A, and consequently more of the weight of thebag 100 is supported by thewheels 116 on thesupport surface 140 and less of the weight is supported by the user at thehandle assembly 122. Thus, the leaninghandle assembly 122 in the towing position reduces the effective weight of thebag 100 experienced by the user and accordingly reduces fatigue when towing thebag 100. - Additionally, the leaning
handle assembly 122 displaces the carrying position of thehandle assembly 122 farther away from theaxis 130 of thebag 100. Thebag 100 is therefore less likely to encroach upon and interrupt the gait pattern of a user when towing thebag 100. -
FIG. 5 is a perspective view of thetowing handle system 102 illustrating thehandle assembly 122 coupled to an end of the support posts 120. Thehandle system 102 includes ahandle retainer housing 150 which is mounted stationary to the support posts 120 with knownfasteners 152, such as rivets. Thehandle retainer housing 150 extends between and connects the support posts 120 to one another, thereby maintaining the support posts 120 in a spaced apart relation to one another. In an exemplary embodiment, thehandle retainer housing 150 is fabricated in two halves (only one of which is shown inFIG. 1 ) and is fabricated from, for example, plastic according to known techniques. The halves of theretainer housing 150 encase a locking latch mechanism (not shown inFIG. 5 but described below) which permits thehandle assembly 122 to move between the upright and towing positions. - The
handle assembly 122 includes a U-shaped frame or shell 154 which is pivotally mounted to thehandle retaining housing 150. Theshell 154 is movable relative to thehandle retainer housing 150, and is selectively positionable between the upright and towing positions in the manner described below. Thumb rests 156 are provided in theshell 154 and thepush button 124 extends through anouter surface 158 of theshell 154. Theshell 154 may be fabricated from, for example, plastic according to a known molding operation. -
FIG. 6 illustrates thehandle assembly 122 removed from the handle retainer housing 150 (shown inFIG. 5 ). Theshell 154 includes aninner portion 160 and anouter portion 162 mating with theinner portion 160. Each of the inner andouter portions shell 152 includeopposite leg members cross member respective leg members - The
inner portion 164 of theshell 154 includes contoured grip surfaces 172. In an exemplary embodiment, the grip surfaces 172 are fabricated from a resilient material such as rubber and are attached to theinner portion 164 of theshell 154 to provide a firm, yet comfortable gripping surface on the interior surfaces of theshell 154. In an alternative embodiment, grip surfaces 172 may be formed into the inner andouter portions shell 154, or still further, the grip surfaces 172 may be omitted in the handle assembly construction. - The
legs 166 of theouter shell portion 162 include mountingfeet 174 located opposite thecross member 170, and the mountingfeet 174 extend inwardly toward one another from thelegs 166 of the U-shapedouter shell 162. The shellinner portion 160 nests within theouter shell portion 162 with thelegs 164 of theinner shell portion 160 resting upon the mountingfeet 174 of theouter shell portion 162. In an exemplary embodiment, each of the mountingfeet 174 includes apivot base 175, analignment face 176 extending from thepivot base 175, aneck 177 extending axially from thealignment face 176, and acradle disk 178 extending axially from theneck 177. Thepivot base 175, theneck 177 and thecradle disk 178 are substantially aligned with one another along atransverse axis 180. Theneck 177 has a reduced cross sectional area relative to thepivot base 175, and thecradle disk 178 has a greater cross sectional area than theneck 177. In an exemplary embodiment, theneck 177 and thecradle disk 178 are substantially cylindrical in shape, while the pivot bases 175 are relatively square to match the contours of thehandle shell 154. The pivot bases 175 are further rounded on abottom surface 180 thereof to provide clearance above the handle retainer housing 150 (FIG. 5 ) as thehandle assembly 122 is moved relative thereto. - When assembled to the handle retainer housing 150 (
FIG. 5 ), the pivot bases 175 of the mountingfeet 174 extend exterior to thehandle retainer housing 150 with thealignment face 176 adjacent outer edges of thehandle retainer housing 150. Thecradle disks 178 are received in cradle slots (not shown) formed in thehandle retainer housing 150, and as such, thecradle disks 178 may rotate within the cradle slots about thetransverse axis 180, but thecradle disks 178 are prevented from moving relative to the handle retainer housing in a direction parallel to thetransverse axis 180. - A locking
latch mechanism 182 extends between the mountingfeet 174 and is generally aligned along thetransverse axis 180 between thecradle disks 178. In an illustrative embodiment, the lockinglatch mechanism 182 includes apositioning shaft 184, stops 186 mounted to theshaft 184, a pair of lockingelements 188, andbias elements 190 extending between thestops 186 and the lockingelements 188. Thepositioning shaft 184 is mounted stationary to the mountingfeet 174 of theshell 154, and the lockingelements 188 are received in cavities (not shown) formed in thehandle retainer housing 150. The lockingelements 188 cooperate with positioningribs shaft 184 to lock thehandle assembly 122 in the upright position and the towing position as set forth below. Thepositioning ribs elements 188, and the lockingelements 188 are slidably mounted to theshaft 184 and are positionable toward and away from theribs - In an exemplary embodiment the
bias elements 190 are helical compression springs, although it is appreciated that other resilient elements and spring elements may be provided to provide a bias force on the lockingelements 188 as described below. Also, in one embodiment, thestops 186 are metal washers which are maintained in a predetermined position by thehandle retainer housing 150 when thehandle assembly 122 is installed. It is contemplated, however, that stops 186 could be formed in theshaft 184 itself or otherwise provided in another known manner, including, for example, providing stop surfaces for the bias elements in thehandle retainer housing 150. -
FIG. 7 is a perspective view of anexemplary positioning shaft 184 including a substantially cylindricalouter surface 200 and thepositioning ribs outer surface 200. Theribs longitudinal axis 206 of theshaft 184, and theribs FIG. 3 ) between the upright and towing positions of thehandle assembly 122. In an exemplary embodiment, the angle α is approximately 45°, although it is understood that greater and lesser angles may be employed in alternative embodiments. The lockingelements 188 extend over theouter surface 200 of the shaft, and when aligned with thepositioning ribs elements 188 latch thehandle assembly 122 in the each of the upright and towing positions to position thehandle assembly 122 with respect to the handle retainer housing 150 (FIG. 5 ) as desired. -
FIG. 8 illustrates an end view of thepositioning shaft 184 and its interaction with anexemplary locking element 188. The lockingelement 188 include apolygonal body 210 having anouter surface 212, aninner surface 214, and arelease arm 216. Theinner surface 214 is substantially cylindrical and is slidaby mounted over the outer circumference of theshaft 184 and therefore completely surrounds thesurface 200 of thepositioning shaft 184.Position slots inner surface 214, and theposition slots positioning ribs shaft 184. - When the locking
elements 188 are released to an unlocked position as explained below, theshaft 184 is rotatable relative to and within theinner surface 214 of the lockingelements 188, while the lockingelements 188 remain in a predetermined alignment within the handle retainer housing 150 (FIG. 5 ). By rotating theshaft 184 relative to the lockingelements 188, the relative positions of thepositioning ribs shaft 184 with respect to thepositioning slots - In an exemplary embodiment, the
release arm 216 of each lockingelement 188 includesengagement slots FIG. 8 ) for actuating the telescoping support posts 120 (FIGS. 2-5 ). Anengagement slot 228 is also provided in theouter surface 212 of the lockingelement body 210, and theslot 228 retains an release wire or cable for actuating the lockingelements 188 as set forth below. Theouter surface 212 of the lockingelements 188 further includes stop features in the form of tabs and slots which cooperate with complementary features in thehandle retainer housing 150 and/or theshaft 184 to restrict relative movement of the lockingelements 188 with respect to theshaft 184 as desired. -
FIGS. 9-11 schematically illustrate the operation of thetowing handle system 102. As illustrated inFIG. 9 , thehandle assembly 122 is coupled to thehandle retainer housing 150, which is, in turn, mounted stationary to the support posts 120. Theshell 154 of thehandle assembly 122 is pivotally mounted to thehandle retainer housing 150 via thecradle disks 178, and the lockinglatch mechanism 182 extends across thehandle retainer housing 150 between the mountingfeet 174. Thestops 186 mounted to theshaft 184 are maintained in a predetermined position with respect to theshaft 184 and thehandle retainer housing 150, and thebias elements 190 are seated against thestops 186 and provide inwardly directed bias forces F upon the lockingelements 188 to maintain the lockingelements 188 in an engaged position with thepositioning ribs shaft 184. Thespring elements 190 provide an equal but oppositely directed force on therespective locking elements 188 to ensure that the lockingelements 188 maintain engagement with theribs shaft 184. - An
actuating assembly 240 is provided in theshell 154 of thehousing assembly 122 for releasing the lockingelements 188 from theshaft 184, and the actuating assembly includes thepush button 124,rocker arms 242, and releasewires 244. -
FIG. 10 schematically illustrates theinner portion 160 of theshell 154 and its configuration for housing the actuating assembly 240 (FIG. 9 ). The shellinner portion 160 is fabricated with apush button seat 250 therein, positioning rails 252 for the rocker arms 242 (shown in phantom inFIG. 10 ), andgrooves 254 which guide the release wires 244 (FIG. 9 ) through theshell 154. The positioning rails 252 include depressedrounded cradles 256 which receivepivot arms 258 of therocker arms 242. Therocker arms 242 may therefore pivot, swing, or rock within thecradles 256 between a locked position (FIG. 9 ) and an unlocked position (FIG. 11 ) when thepushbutton 124 is depressed downwardly into the shell 154 (i.e., in a direction of arrow B). - As demonstrated in
FIGS. 9 and 11 , when thepushbutton 124 is depressed in the direction of arrow B, alower rim 260 of thepushbutton 124 displaces afirst end 262 of therocker arms 242 downward in the direction of arrow B. The displacement of thefirst end 262 causes therocker arms 242 to rock on thepivot arms 258 within theshell 154, and asecond end 264 of therocker arms 242 is displaced upwardly in the direction of arrow C (FIG. 11 ). Therelease wires 244 are attached to thesecond end 264 of therocker arms 242, and the upward displacement of the second ends 264 pulls therelease wires 244 which are coupled to therespective locking elements 188. The pulling of therelease wires 244 displaces the lockingelements 188 in opposite directions D and E (FIG. 11 ) toward the respective mountingfeet 174 of thehandle assembly 122. The release wires 144 pull and axially displace the lockingelements 188 in the direction of arrows D and E against the bias force F (FIG. 9 ) until the lockingelements 188 clear thepositioning ribs FIG. 11 . In the unlocked position, thehandle shell 154 and thepositioning shaft 184 may be freely rotated about thetransverse axis 180 to change the relative position of thehandle assembly 122 with respect to the lockingelements 188, and correspondingly moving thehandle assembly 122 between the upright position and the towing position. - As the
handle assembly 122 and theshaft 184 are rotated within the lockingelements 188 in the unlocked position, when theshaft 184 is once again aligned with the locking elements wherein thepositioning ribs elements 188, the bias force F generated by thebias elements 190 forces the lockingelements 188 back toward one another to the locked position shown inFIG. 9 wherein the locking elements are engaged to theribs bias elements 190 therefore automatically returns the lockingelements 188 to the locked position when the upright and towing positions are obtained, and the user need do nothing to find the appropriate handle position. Rather, thehandle assembly 122 automatically locks into place when the towing position and uptight position are obtained. - Further, as the locking elements move to the locked position, the
release wires 244 are pulled back to the locked position shown inFIG. 9 , which returns the rockingarms 242 to their original position. Thelower rim 260 of thepush button 124 is displaced upwardly by thefirst end 262 of therocker arms 242 as therocker arms 242 return to position. Thus, thepushbutton 124 automatically returns to the locked position shown inFIG. 9 as the selected position of the handle assembly 122 (i.e., the upright position or the towing position) is obtained. - Additionally, the support posts 120 include
respective release wires 270, 272. Therelease wires 270, 272 are attached to the lockingelements 188 at attachment points 274, 276, respectively. On each of the lockingelements 188, one of theslots 224, 226 (FIG. 8 ) in the release arm 216 (FIG. 8 ) serves as a guide for one of thewires 270, 272, and the other of theslots wires 270, 272. Thus, for each of the lockingelements 188, one of theslots release wires 270, 272, and the other of theslots connection point respective wires 270, 272. - When the
actuating assembly 240 is actuated to move the lockingelements 188 to the unlocked position (FIG. 11 ), the movement of the lockingelements 188 in the direction of arrows D and E pulls therelease wires 270 and 272 within the telescoping supports 120 to release a mechanism (not shown) and unlock the support posts for extension of the support posts 120 from thebag 100 or retracting the support posts 120 into thebag 100. Likewise, as the lockingelements 188 return to the locked position (FIG. 9 ), the lockingelements 188 return thewires 270, 272 to their original position with thesupports 120 engaged in a locked position, whether extended or retracted. - The
actuation assembly 240, via the lockingelements 188, therefore serves to simultaneously actuate thehandle assembly 122 for rotation about thetransverse axis 180 and the telescoping supports 120. A user may therefore extend and retract thesupports 120 and rotate the handle between the upright and towing positions with one hand in a simple and direct manner by actuating thepushbutton 124 and guiding thehandle assembly 122 to the desired position. When thehandle assembly 122 and/or the telescoping supports 120 are properly aligned, thepush button 124 automatically returns to its original position and theactuating assembly 240 is effectively reset to its locked position. - The above described
handle assembly 122 and towinghandle system 102 presents a reliable handle system for towing abag 100 which is convenient for persons towing thebag 100, more comfortable than many known handle system for towing bags, and is reliable in operation. When extended and leaned to the angle α (FIG. 3 ), thebag 100 is less likely to interrupt the gait pattern of a towing person thebag 100. - While the
handle assembly 122 is illustrated and described as being movable from an upright position to a singular towing position at the angle α, it is understood that the lockingelements 188 and thepositioning shaft 184 may be appropriately modified to facilitate positioning of the handle at other angular positions either greater than or less than the angle α as desired. Additional towing positions may be provided by adding more positioning ribs to theshaft 184 and more slots to the lockingmembers 188. -
FIG. 12 is a schematic assembly view of another exemplary embodiment of baggage towinghandle assembly 300 which is positionable to a towing position at an angle α with respect to telescoping supports (not shown inFIG. 12 ) for more comfortable towing of a bag, such as the bag 100 (shown inFIGS. 1-4 ). Thehandle assembly 300 includes aninner shell 302 having anactuation assembly 304 mounted thereon, and anouter shell 306 which is fitted to theinner shell 302 to form a U-shaped handle assembly. Theinner shell 302 includes mountingfeet 308 andcradle disks 310 extending therefrom. Theactuation assembly 304 includes apush button 312,rocker arms 314 mounted proximate thepush button 312, and releasewires 316 coupled to therocker arms 314. Each of the release wires are coupled to a known spring loadedlocking mechanism 318 and a pair of lock pins 320 actuated by the lockingmechanisms 318. The lock pins 320 face inwardly toward one another, and eachlock pin 320 include agroove 322 formed therein. -
FIG. 13 illustrates thehandle 320 with theinner shell 302 and theouter shell 306 assembled. The lock pins 320 extend through aresilient bias element 330 which biases the lock pins 320 toward a predetermined orientation, and arelease lever 332 is attached to eachrespective lock pin 330. -
FIG. 14 is an exploded view of anexemplary bias element 330, and in an exemplary embodiment thebias element 330 includes outerrigid layers 340 and anelastic layer 342 sandwiched therebetween. Therigid layers 340 include arc-shapedslots 344 and theelastic layer 342 includes around aperture 346 dimensioned to receive a lock pin 320 (FIG. 13 ). When assembled, theelastic layer 342 is secured between therigid layers 340 and thelock pin 320 extends through theslots 344 of therigid layers 340 and theaperture 346 of theelastic layer 342. Theelastic layer 342 is deformable and allows thepin 320 to move within the confines of theslots 344 to select a handle position, yet is resilient enough that once a handle position is selected, theelastic layer 342 moves thelock pin 320 back to its original position to lock thehandle assembly 300 in place. Therigid layers 340 may be fabricated from, for example, stamped steel, and theelastic layer 342 may be fabricated from, for example, an elastomeric rubber material. -
FIG. 15 illustrates anexemplary release lever 332 which includes alower section 350, andupper section 352, and pivotarms 354 extending outwardly in between the upper andlower sections lower section 352 includes aclosed slot 356 which retains a release wire (not shown) for the telescoping supports (not shown inFIG. 1 ) used with thehandle assembly 300. The upper section defines anopen slot 358 which receives the groove 322 (FIG. 12 ) in alock pin 320. Theupper section 352 is retained in thelock pin groove 320 such that when the lock pins 320 move in the direction of arrow G (FIG. 13 ), the release levers 332 pivot about the pivot arms and pull release wires attached to thelower section 350 to actuate the telescoping supports. -
FIGS. 16 and 17 further illustrate thehandle assembly 300 and a lockinglatch mechanism 368 including anactuator housing 360 which may be fixedly mounted to telescoping support posts (not shown) when the posts are received insupport receptacles 362 formed in thehousing 360. Thehousing 360 defines a cavity (not shown) which receives adial position selector 370 having a base 372 includingapertures 374 for receiving the lock pins 320, positioningportions 376 extending upward from thebase 374, and abutton portion 378 extending between the positioningportions 376. The positioningportions 376 include a ribbedouter surface 378 having projections or teeth extending thereon which are aligned a predetermined intervals with respect to one another. In an exemplary embodiment, the ribs or teeth are positioned at 8° increments, although it is understood that greater or lesser angular separation may be employed in further and/or alternative embodiments. Thedial position selector 370 further includes alower extension 380 having receptacles therein providing a seat for bias elements 384 (FIG. 17 ), such as helical coil spring elements. - When the
dial position selector 370 is fitted within theactuator housing 360 as shown inFIG. 17 , lockingplates 386 are extended over thedial position selector 370, and thepositioning portions 376 of theposition selector 370 are biased against the lockingplates 386. As illustrated inFIG. 16 , aninner surface 388 of the lockingplates 386 are ribbed in a complementary manner to thepositioning portions 376 of thedial position selector 370, wherein thepositioning portions 376 and theinner surfaces 388 may mesh with one another in a tongue and groove configuration to orient thedial position selector 370 with respect to the lockingplates 386 and hence determine a stable orientation of thehandle assembly 300 with respect to theactuator housing 360. Stable orientations may be provided at each angular increment according to the increments of the ribs in the respective surfaces of the lockingplates 386 and thedial position selector 370. Thus, the handle assembly may be positioned at a number of different angles (e.g., 37°, 45° and 53°) with respect to theactuator housing 360 to provide a number of different towing positions, in addition to the upright position. -
FIG. 17 illustrates thehandle assembly 300 in an assembled condition wherein acover plate 400 retains the lockinglatch assembly 368 together. Thebias elements 384 provide an upwardly directed force in the direction of arrow H on theposition selector 370, and the bias force maintains thedial position selector 370 in contact with the lockingplates 386. To release thehandle assembly 300 for rotation from an upright position to a towing position, or from one towing position to another, thepush button 312 is depressed downwardly in the direction of arrow I, which cause therocker arms 314 to pivot and pull therelease wires 316 to actuate the lockingmechanisms 318 and pull the lock pins 320 in opposite directions J and K away from thedial position selector 370. Once the lock pins 320 are free of theposition selector 370, thebutton 378 of thedial position selector 370 may be depressed downwardly in the direction of arrow I, and theselector 370 is displaced downwardly against the bias of thebias elements 384. - Once the position surfaces 376 of the
selector 370 clear theinner surfaces 388 of the lockingplates 386 when thebutton 378 is depressed, the lockingplates 386 and the handle shell may be rotated over thedial position selector 370 to another relative orientation. When thebutton 378 of thedial position selector 370 is released, thebias elements 384 return thedial position selector 370 upwardly in the direction of arrow H until the positioning surfaces 376 of thedial position selector 370 lockingly engage the lockingplates 386 in a locked position. The spring loaded lockingmechanisms 318 engage the locking pins 320 in the new position and the handle is ready for towing. - Additionally, when the
push button 312 is actuated to move the locking pins 320 to the unlocked position, the movement of the locking pins 320 in the direction of arrows J and K cause the release levers 332 to pivot and pullsrelease wires 316 within the telescoping supports to release a mechanism (not shown) and unlock the support legs for extension or retraction from the associated bag. - Thus, unlike the
handle assembly 122 described above, thehandle assembly 300 utilizes two step actuation to release and rotate thehandle assembly 300. Nonetheless, and like thehandle assembly 122, thehandle assembly 300 presents a reliable handle system for towing a bag which is convenient for persons towing the bag, more comfortable than many known handle system for towing bags, and is reliable in operation. When extended and leaned to an angle α (as illustrated inFIG. 3 ), thehandle 300 is less likely to interrupt the gait pattern of a person towing person the bag. - While the invention has been described in terms of various specific embodiments, those skilled in the art will recognize that the invention can be practiced with modification within the spirit and scope of the claims.
