Definitions
- This invention relates to an infant car seat including a foldable handle that may be rotated between a carrying position (in which an infant in the car seat may be carried) and a storage position (in which access to a seating area in the car seat is facilitated).
- Rear-facing infant car seats generally include a base that can be secured to a vehicle seat and an infant carrier detachably coupled to the base.
- the infant carrier has a carrying handle so that a parent can carry a sleeping child from car to home without disturbing the child.
- the infant carrier also can be snapped onto a stroller to make a travel system.
- the infant carrier can play an important part in daily parental care of a child, and ease of use of the infant carrier is critical to parents.
- Carriers with handles generally have a handle lock on each side of the carrier, both of which must be released to rotate the handle away from the child seating area. Oftentimes, the handle is left in the up (or carrying) position.
- the parent goes to place the child in the carrier, the parent cannot simultaneously manipulate the handle and hold the child. Instead, the parent must set the child down, away from the carrier, then use both hands to unlock and rotate the handle away from the child seating area, and finally lift and place the child in the carrier. This sequence can be awkward, frustrating, and time-consuming for the parent.
- An embodiment of the present invention relates to a carrier configured to be secured to a base of an infant seat.
- This carrier includes, among other possible things: a seat shell including an infant seating area and first and second handle mounts on opposite sides of the infant seating area; a handle rotatably coupled to the seat shell such that first and second ends of the handle are mounted to the first and second handle mounts, respectively; first and second locking mechanisms associated with the first and second ends of the handle, respectively, the first and second locking mechanisms being configured to lock the handle relative to the seat shell; and an actuator mounted to the handle, the actuator being configured to unlock the first and second locking mechanisms solely by moving the actuator from a locked position to an unlocked position relative to the handle.

- the handle gripping portion 112 which extends along a substantial portion of the horizontal portion of adjustable handle 110 , allows a person carrying the carrier 100 to grip the handle 110 comfortably at any point along the handle gripping portion 112 .
- the handle 110 is connected to the seat shell 120 at two handle ends 118 , each of which contains a locking mechanism 200 (shown in FIG. 2 ) that is configured to releasably fix the orientation of the handle 110 with respect to the seat shell 120 .
- the handle 110 is configured to be locked (by means of the locking mechanisms 200 associated with the handle ends 118 ) in several distinct rotational positions including, but not limited to, a carrying position (shown in FIG. 1A ) and a stored position (shown in FIG. 1B ).
- a carrying position shown in FIG. 1A
- a stored position shown in FIG. 1B
- a parent In the carrying position, a parent may carry an infant seated in the seating portion 105 .
- a parent In the stored position, in which the handle 110 does not impede direct access to the seating portion 105 , a parent can easily place an infant in the seating portion 105 or remove the infant from the seating portion 105 .
- the seat shell 120 and the adjustable handle 110 may be constructed of any appropriate rigid material.
- the seat shell 120 and the adjustable handle 110 may be constructed of metal or a high-strength plastic such as an injection molded plastic.
- FIG. 2 shows an exploded isometric view of the locking mechanism 200 of the carrier 100 . It is to be understood that although only one locking mechanism 200 is shown and described, locking mechanisms 200 are provided on both ends of the handle 110 . Accordingly, the following discussion of the locking mechanism 200 is equally applicable to the locking mechanism at the other end of the handle 110 .
- the locking mechanism 200 may include a locking member 220 , a locking member receiving portion 210 at the end 118 of the handle 110 , and a handle mount 240 formed on a side of the seat shell 120 .
- the locking member 220 includes a recess portion 221 , a conical portion 222 , a cylindrical portion 224 , alignment locking tabs 227 , a plurality of teeth 229 , which include at least one key tooth 228 , and over-rotation prevention tabs 226 .

- the handle 110 includes the locking member receiving portion 210 , which, in turn, includes over-rotation prevention tabs 212 and locking ridges 216 .
- Small gaps 218 and large gaps 214 are formed between locking ridges 216 .
- the large gaps 214 are configured to engage the at least one key tooth 228 , or two teeth 229 .
- the small gaps 218 are configured to engage a single tooth 229 and will not receive the key tooth 228 due to their size.
- the over-rotation prevention tabs 212 are configured to engage the over-rotation prevention tabs 226 of the locking member 220 to limit the extent of rotation of the handle 110 with respect to locking member 220 .
- the handle 110 and associated components of the locking mechanism 200 may be constructed of any appropriate rigid material.
- the handle 110 and its locking member receiving portion 210 including tabs 212 and locking ridges 216 , may be constructed of metal or a high-strength plastic such as an injection molded plastic.
- Locking mechanism 200 also may include a biasing spring 230 to urge the conical portion 222 of the locking member 220 towards the locking member receiving portion 210 of the handle 110 .
- the handle mount 240 can receive one end of the biasing spring 230 .
- the other end of the spring 230 can be received in the recess 221 in the locking member 220 .
- the biasing spring 230 biases the locking member 220 and its conical portion 222 toward the handle 110 . More specifically, the biasing spring 230 biases the locking member 220 so that it is partially received in the locking member receiving portion 210 of the handle 110 , whereas the remainder of the locking member 220 is received in the handle mount 240 .
- biasing spring 230 biases the locking member 220 to engage both the locking member receiving portion 210 of the handle 110 and the handle mount 240 , movement of the locking member receiving portion 210 (and, therefore, the handle 110 ) with respect to the handle mount 240 can be releasably inhibited.

- the handle 110 includes locking member receiving portion 210 , over-rotation prevention tabs 212 , locking ridges 216 , small gaps 218 , and large gaps 214 .
- handle 110 includes a pin hole 310 , which is configured to receive the pin 270 , and a raised cylindrical boss 315 .
- the handle 100 may include three pairs of large gaps 214 and, therefore, have three distinct locking positions. However, it should be understood that any number of distinct locking positions could be accommodated without departing from the spirit and scope of the invention.
- FIG. 4A shows a front view of the locking member 220 .
- the locking member 220 includes conical portion 222 having a tip 223 , cylindrical portion 224 , alignment locking tabs 227 , teeth 229 (including the at least one key tooth 228 ), over-rotation prevention tabs 226 , and a pin hole 510 .
- the other side of the locking member 220 which is shown in FIG. 4B , includes the recess portion 221 .
- FIG. 5A shows an isometric view of the handle mount 240 .
- the handle mount 240 includes a pin hole 610 , a spring mounting surface 620 , locking tab receiving cut-outs 630 , locking ridges 640 , and key tooth receiving gaps 650 .
- FIG. 5B which is a front view of the handle mount 240
- the key tooth receiving gaps 650 are configured to receive the key teeth 228
- the locking ridges 640 are configured to receive the other teeth 229 .
- the biasing spring 230 is placed between pin hole 610 and the spring mounting surface 620 .
- the locking member 220 is placed into the handle mount 240 until alignment locking tabs 227 engage the locking tab receiving cut-outs 630 . As a result, the locking member 220 is biased away from the handle mount 240 toward the locking member receiving portion 210 .
- the locking tab receiving cut-outs 630 are longer in the axial direction than the alignment locking tabs 227 .
- the locking member 220 is able to move axially (when biasing spring 230 is compressed) with respect to the handle mount 240 , without becoming completely disengaged from the handle mount 240 .
- the locking member 220 is prevented from rotating with respect to the handle mount 240 when the locking member 220 is received in the handle mount 240 as a result of the engagement of the teeth 229 and the locking ridges 640 .
- FIGS. 6A-9B A first actuator assembly embodiment will be described with respect to FIGS. 6A-8B and an alternate actuator assembly embodiment will subsequently be described with respect to FIGS. 9A and 9B . Preliminarily, however, certain components of the locking mechanism 200 of each of the actuator assembly embodiments will be discussed with reference to FIGS. 6A-6E .
- the locking mechanism 200 can include the locking member 220 , the locking member receiving portion 210 , the spring 230 , and the handle mount 240 .
- a cord engagement member 250 can interface with the locking member 220 .
- FIG. 6A is a exploded, isometric, partial cut-away view of a portion of the handle 110 of the carrier 100 and illustrates the positioning of the cord engagement member 250 in the locking member receiving portion 210 and relative to the locking member 220 .
- the cord engagement member 250 is positioned against an inner wall 150 of the locking member receiving portion 210 to slide along the inner wall 150 upon actuation of the actuator assembly.
- the cord engagement member 250 includes a generally triangular or trapezoidal slot 252 to receive the conical portion 222 of the locking member 220 .
- the conical portion 222 of the locking member 220 is urged into slot 252 of the cord engagement member 250 by spring 230 .
- the end of the conical portion 222 resides within the triangular slot 252 . More specifically, the end of the conical portion 222 spans the wider base 254 of the triangular slot 252 such that, as seen in FIG. 6B , a tip 223 of the conical portion 222 is not in contact with the sides of the triangular slot 252 .
- the teeth 229 of the locking member 220 are engaged with both the small gaps 218 of the locking member receiving portion 210 of the handle 110 and the locking ridges 640 of the handle mount 240 .
- the key teeth 228 are engaged with the large gaps 214 in the locking member receiving portion 210 of the handle 110 and the key tooth receiving gaps 650 of the handle mount 240 .
- the conical portion 222 When the conical portion 222 is moved laterally to the position in FIG. 6E , the biasing spring 230 is compressed, and the locking member 220 is pushed completely into the handle mount 240 to an actuated position.
- the teeth 229 of the locking member 220 are disengaged from the small gaps 218 in the locking member receiving portion 210 of the handle 110 and are completely housed in the locking ridges 640 of the handle mount 240 .
- the key teeth 228 are forced out of the large gaps 214 in the locking member receiving portion 210 of the handle 110 and are completely housed in the key tooth receiving gaps 650 of the handle mount 240 .
- the locking member 220 When the locking member 220 is completely housed in the handle mount 240 , the locking member 220 is corresponding completely disengaged from the locking member receiving portion 210 of the handle 110 . As a result, the handle 110 is able to rotate with respect to the locking member 220 and the handle mount 240 . For example, the handle 110 may be rotated from the carrying position (shown in FIG. 1A ) to the stored position (shown in FIG. 1B ) in which the padded seating portion 105 is readily accessible.
- the locking member 220 When the handle 110 is rotated to a desired position at which the key teeth 228 are aligned with the large gaps 214 in the locking member receiving portion 210 of the handle 110 , the locking member 220 may be returned to the resting state, as later described in detail. To return the locking member 220 to the resting state, the biasing spring 230 pushes the locking member 220 into the locking member receiving portion 210 of the handle 110 , thereby once again locking the handle 110 with respect to the locking member 220 and the handle mount 240 .
- the invention contemplates an actuator assembly, such as the embodiments shown in FIGS. 7A-8C and 9 B- 9 B.
- FIGS. 7A-8C An exemplary actuator assembly 800 is shown in FIGS. 7A-8C .
- this actuator assembly 800 is discussed with respect to the locking mechanism 200 on one side of the carrier 100 . It is be understood, however, that the other locking mechanism 200 (i.e., the one on the other side of the carrier) is actuated in the same manner and by the same actuator assembly 800 .
- Actuator assembly 800 can include a cord 810 that terminates at cord engagement member 250 (shown in more detail in FIGS. 6A-6E ), a cord connector 830 , and a push-button actuator 820 .
- the cord 810 which may be made out of a flexible but strong material (e.g., a polymer, rope, wire, etc.), connects the cord connector 830 to the cord engagement member 250 .
- the cord connector 830 , the cord 810 , and the cord engagement member 250 may be integrally formed. Alternatively, these three components may be formed separately and then subsequently adjoined.
- a portion 822 of the push-button actuator 820 projects through the handle 110 and is, therefore, externally accessible to a user for purposes of actuation, as hereafter described with respect to FIGS. 8A-8C .
- FIGS. 8A and 8B it can be seen that a sloped surface 824 of the push-button 820 is received within a slot 832 formed in the cord connector 830 .
- the accessible portion 822 of the push-button actuator 820 is pushed into the handle 110 (i.e., in the direction of arrow ⁇ shown in FIGS. 7A and 8C )
- the cord connector 830 rides along the sloped surface 824 , thereby moving toward the center 160 of the handle 110 (i.e., in the direction of arrow ⁇ ).
- the cord connector 830 moves toward the center of the handle 110 , it pulls the cord 810 and, in turn, the cord engagement member 250 toward the center 160 of the handle 110 .
- the cord engagement member 250 moves in the direction of arrow ⁇ , shown in FIG. 7A .
- the locking member 220 moves laterally inward with respect to the cord engagement member 250 .
- the locking member 220 moves in the direction of arrow ⁇ (as shown in FIG. 7A ) and is, therefore, forced into the actuated state, previously discussed with respect to FIGS. 6D and 6E .

Abstract
An infant carrier includes a seat shell and a handle. The handle may be moved between a carrying position and a storage position by actuating, with only one hand, an actuator assembly provided in the handle. When actuated, an actuator of the actuator assembly disengages locking mechanisms associated with first and second ends of the handle where the handle is joined to the seat shell. The disengagement of the locking mechanisms enables to the handle to be rotated with respect to the seat shell.
Description
- This application claims the benefit of U.S. Provisional Application No. 60/525,849, filed Dec. 1, 2003, and U.S. Provisional Application No. 60/561,530, filed Apr. 13, 2004, both of which are incorporated by reference in their entireties.
- This invention relates to an infant car seat including a foldable handle that may be rotated between a carrying position (in which an infant in the car seat may be carried) and a storage position (in which access to a seating area in the car seat is facilitated).
- Rear-facing infant car seats generally include a base that can be secured to a vehicle seat and an infant carrier detachably coupled to the base. The infant carrier has a carrying handle so that a parent can carry a sleeping child from car to home without disturbing the child. The infant carrier also can be snapped onto a stroller to make a travel system. Thus, the infant carrier can play an important part in daily parental care of a child, and ease of use of the infant carrier is critical to parents.
- When a parent wants to place a child in the carrier, the carrying handle needs to be away from the child seating area (i.e., in the stored position) so the child can be secured safely in the carrier. Carriers with handles generally have a handle lock on each side of the carrier, both of which must be released to rotate the handle away from the child seating area. Oftentimes, the handle is left in the up (or carrying) position. When the parent goes to place the child in the carrier, the parent cannot simultaneously manipulate the handle and hold the child. Instead, the parent must set the child down, away from the carrier, then use both hands to unlock and rotate the handle away from the child seating area, and finally lift and place the child in the carrier. This sequence can be awkward, frustrating, and time-consuming for the parent.
- In light of the foregoing, there is a need in the art for an infant carrier with an improved handle release and rotation mechanism.
- An embodiment of the present invention relates to a carrier configured to be secured to a base of an infant seat. This carrier includes, among other possible things: a seat shell including an infant seating area and first and second handle mounts on opposite sides of the infant seating area; a handle rotatably coupled to the seat shell such that first and second ends of the handle are mounted to the first and second handle mounts, respectively; first and second locking mechanisms associated with the first and second ends of the handle, respectively, the first and second locking mechanisms being configured to lock the handle relative to the seat shell; and an actuator mounted to the handle, the actuator being configured to unlock the first and second locking mechanisms solely by moving the actuator from a locked position to an unlocked position relative to the handle.
- Another embodiment of the present invention relates to an infant carrier that includes, among other possible things: a seat shell including an infant seating area, a first handle mount, and a second handle mount; a handle rotatably coupled to the first and second handle mounts; first and second locking mechanisms associated with the first and second handle mounts, respectively, the first and second locking mechanisms being configured to lock the handle relative to the seat shell; and an actuator assembly that is mounted to the handle, the actuator assembly being configured to engage and disengage the first and second locking mechanisms thereby enabling the handle to rotate with respect to the seat shell.
- Another embodiment of the present invention relates to a carrier configured to be secured to a base of an infant seat. This carrier includes, among other possible things: a seat shell including an infant seating area and first and second handle mounts on opposite sides of the infant seating area; a handle rotatably coupled to the seat shell such that first and second ends of the handle are mounted to the first and second handle mounts, respectively; at least one locking mechanism associated with one of the first and second ends of the handle, the at least one locking mechanism being configured to lock the handle relative to the seat shell; and an actuator provided in the handle in a position intermediate the first and second ends of the handle, the actuator being configured to unlock the at least one locking mechanism solely by moving the actuator from a locked position to an unlocked position relative to the handle.
- Another embodiment of the present invention relates to an infant carrier that includes, among other possible things: a seat shell including an infant seating area, a first handle mount, and a second handle mount; a handle rotatably coupled to the first and second handle mounts; at least one locking mechanism associated with one of the first and second handle mounts, the at least one locking mechanism being configured to lock the handle relative to the seat shell; and an actuator mounted to the handle, the actuator being configured to unlock all of the locking mechanisms solely by moving the actuator from a locked position to an unlocked position relative to the handle.

-
FIGS. 1A and 1B illustrate aninfant carrier 100 having anadjustable handle 110 that can be folded with one hand according to an exemplary embodiment of the invention. - The
carrier 100 includes aseat shell 120, a paddedseating portion 105 serving as an infant seating area, anadjustable handle 110, ahandle gripping portion 112, and ahandle actuator 820. Thehandle gripping portion 112, which extends along a substantial portion of the horizontal portion ofadjustable handle 110, allows a person carrying thecarrier 100 to grip thehandle 110 comfortably at any point along thehandle gripping portion 112. - The
handle 110 is connected to theseat shell 120 at two handle ends 118, each of which contains a locking mechanism 200 (shown inFIG. 2 ) that is configured to releasably fix the orientation of thehandle 110 with respect to theseat shell 120. Specifically, thehandle 110 is configured to be locked (by means of the lockingmechanisms 200 associated with the handle ends 118) in several distinct rotational positions including, but not limited to, a carrying position (shown inFIG. 1A ) and a stored position (shown inFIG. 1B ). In the carrying position, a parent may carry an infant seated in theseating portion 105. In the stored position, in which thehandle 110 does not impede direct access to theseating portion 105, a parent can easily place an infant in theseating portion 105 or remove the infant from theseating portion 105. - The
seat shell 120 and theadjustable handle 110 may be constructed of any appropriate rigid material. For example, theseat shell 120 and theadjustable handle 110 may be constructed of metal or a high-strength plastic such as an injection molded plastic. -
FIG. 2 shows an exploded isometric view of thelocking mechanism 200 of thecarrier 100. It is to be understood that although only onelocking mechanism 200 is shown and described, lockingmechanisms 200 are provided on both ends of thehandle 110. Accordingly, the following discussion of thelocking mechanism 200 is equally applicable to the locking mechanism at the other end of thehandle 110. Thelocking mechanism 200 may include a lockingmember 220, a lockingmember receiving portion 210 at theend 118 of thehandle 110, and ahandle mount 240 formed on a side of theseat shell 120. - The locking
member 220 includes arecess portion 221, aconical portion 222, acylindrical portion 224,alignment locking tabs 227, a plurality ofteeth 229, which include at least onekey tooth 228, andover-rotation prevention tabs 226. The lockingmember 220 may be constructed of any appropriate rigid material. For example, lockingmember 220 may be constructed of metal or a high-strength plastic such as an injection molded plastic. - The
handle 110 includes the lockingmember receiving portion 210, which, in turn, includesover-rotation prevention tabs 212 and lockingridges 216.Small gaps 218 andlarge gaps 214 are formed between lockingridges 216. Thelarge gaps 214 are configured to engage the at least onekey tooth 228, or twoteeth 229. In contrast, thesmall gaps 218 are configured to engage asingle tooth 229 and will not receive thekey tooth 228 due to their size. Theover-rotation prevention tabs 212 are configured to engage theover-rotation prevention tabs 226 of the lockingmember 220 to limit the extent of rotation of thehandle 110 with respect to lockingmember 220. Thehandle 110 and associated components of thelocking mechanism 200 may be constructed of any appropriate rigid material. For example, thehandle 110 and its lockingmember receiving portion 210, includingtabs 212 and lockingridges 216, may be constructed of metal or a high-strength plastic such as an injection molded plastic. -
Locking mechanism 200 also may include abiasing spring 230 to urge theconical portion 222 of the lockingmember 220 towards the lockingmember receiving portion 210 of thehandle 110. Thehandle mount 240 can receive one end of the biasingspring 230. The other end of thespring 230 can be received in therecess 221 in the lockingmember 220. Thus, the biasingspring 230 biases the lockingmember 220 and itsconical portion 222 toward thehandle 110. More specifically, the biasingspring 230 biases the lockingmember 220 so that it is partially received in the lockingmember receiving portion 210 of thehandle 110, whereas the remainder of the lockingmember 220 is received in thehandle mount 240. As the biasingspring 230 biases the lockingmember 220 to engage both the lockingmember receiving portion 210 of thehandle 110 and thehandle mount 240, movement of the locking member receiving portion 210 (and, therefore, the handle 110) with respect to thehandle mount 240 can be releasably inhibited. -
FIG. 2 also shows apin 270 that serves as an axle for the rotation of thehandle 110. Thepin 270 passes through the lockingmember receiving portion 210 of thehandle 110, the lockingmember 220, the biasingspring 230, and thehandle mount 240 to secure the entire assembly together. Although not shown, thepin 270 may have threads thereon (e.g., thepin 270 may be in the form of a screw) that are configured to engage matching threads formed in or on thehandle mount 240. However, it should be understood that thepin 270 may be formed from any appropriate attachment mechanism such as a screw, a bolt, a shaft with a lock pin, etc. -
FIG. 3 shows a front view of a portion of ahandle 110. Thehandle 110 includes lockingmember receiving portion 210,over-rotation prevention tabs 212, lockingridges 216,small gaps 218, andlarge gaps 214. Furthermore, handle 110 includes apin hole 310, which is configured to receive thepin 270, and a raisedcylindrical boss 315. As shown, thehandle 100 may include three pairs oflarge gaps 214 and, therefore, have three distinct locking positions. However, it should be understood that any number of distinct locking positions could be accommodated without departing from the spirit and scope of the invention. -
FIG. 4A shows a front view of the lockingmember 220. The lockingmember 220 includesconical portion 222 having atip 223,cylindrical portion 224,alignment locking tabs 227, teeth 229 (including the at least one key tooth 228),over-rotation prevention tabs 226, and apin hole 510. The other side of the lockingmember 220, which is shown inFIG. 4B , includes therecess portion 221. -
FIG. 5A shows an isometric view of thehandle mount 240. Thehandle mount 240 includes apin hole 610, aspring mounting surface 620, locking tab receiving cut-outs 630, lockingridges 640, and keytooth receiving gaps 650. As shown inFIG. 5B , which is a front view of thehandle mount 240, the keytooth receiving gaps 650 are configured to receive thekey teeth 228, while the lockingridges 640 are configured to receive theother teeth 229. During assembly, the biasingspring 230 is placed betweenpin hole 610 and thespring mounting surface 620. Subsequently, the lockingmember 220 is placed into thehandle mount 240 untilalignment locking tabs 227 engage the locking tab receiving cut-outs 630. As a result, the lockingmember 220 is biased away from thehandle mount 240 toward the lockingmember receiving portion 210. - With reference to
FIGS. 2 and 5 A, the locking tab receiving cut-outs 630 are longer in the axial direction than thealignment locking tabs 227. Thus, the lockingmember 220 is able to move axially (when biasingspring 230 is compressed) with respect to thehandle mount 240, without becoming completely disengaged from thehandle mount 240. However, the lockingmember 220 is prevented from rotating with respect to thehandle mount 240 when the lockingmember 220 is received in thehandle mount 240 as a result of the engagement of theteeth 229 and the lockingridges 640. - Adjustment of the
handle 110 of thecarrier 100 now will be described in detail with reference to actuator assembly embodiments shown inFIGS. 6A-9B . A first actuator assembly embodiment will be described with respect toFIGS. 6A-8B and an alternate actuator assembly embodiment will subsequently be described with respect toFIGS. 9A and 9B . Preliminarily, however, certain components of thelocking mechanism 200 of each of the actuator assembly embodiments will be discussed with reference toFIGS. 6A-6E . - As stated above, the
locking mechanism 200 can include the lockingmember 220, the lockingmember receiving portion 210, thespring 230, and thehandle mount 240. Acord engagement member 250 can interface with the lockingmember 220.FIG. 6A is a exploded, isometric, partial cut-away view of a portion of thehandle 110 of thecarrier 100 and illustrates the positioning of thecord engagement member 250 in the lockingmember receiving portion 210 and relative to the lockingmember 220. Thecord engagement member 250 is positioned against aninner wall 150 of the lockingmember receiving portion 210 to slide along theinner wall 150 upon actuation of the actuator assembly. In addition, thecord engagement member 250 includes a generally triangular ortrapezoidal slot 252 to receive theconical portion 222 of the lockingmember 220. Theconical portion 222 of the lockingmember 220 is urged intoslot 252 of thecord engagement member 250 byspring 230. - As shown in
FIGS. 6B and 6C , in a resting position, the end of theconical portion 222 resides within thetriangular slot 252. More specifically, the end of theconical portion 222 spans thewider base 254 of thetriangular slot 252 such that, as seen inFIG. 6B , atip 223 of theconical portion 222 is not in contact with the sides of thetriangular slot 252. Further, theteeth 229 of the lockingmember 220 are engaged with both thesmall gaps 218 of the lockingmember receiving portion 210 of thehandle 110 and the lockingridges 640 of thehandle mount 240. Similarly, thekey teeth 228 are engaged with thelarge gaps 214 in the lockingmember receiving portion 210 of thehandle 110 and the keytooth receiving gaps 650 of thehandle mount 240. - By comparison, in an actuated state shown in
FIGS. 6D and 6E (in which thecord engagement member 250 is pulled toward the center of thehandle 110, as later explained in detail), theconical portion 222 of the lockingmember receiving portion 210 is drawn into contact with thetriangular slot 252. As a result, thetip 223 of theconical portion 222 comes into contact with thepeak 256 and the sides of thetriangular slot 252. In addition, as a result of the narrowing of thetriangular slot 252, as theconical portion 222 nears thepeak 256, theconical portion 222 is moved laterally out of theslot 252, away from the lockingmember receiving portion 210 and toward thehandle mount 240. - When the
conical portion 222 is moved laterally to the position inFIG. 6E , the biasingspring 230 is compressed, and the lockingmember 220 is pushed completely into thehandle mount 240 to an actuated position. In other words, theteeth 229 of the lockingmember 220 are disengaged from thesmall gaps 218 in the lockingmember receiving portion 210 of thehandle 110 and are completely housed in the lockingridges 640 of thehandle mount 240. Similarly, thekey teeth 228 are forced out of thelarge gaps 214 in the lockingmember receiving portion 210 of thehandle 110 and are completely housed in the keytooth receiving gaps 650 of thehandle mount 240. - When the locking
member 220 is completely housed in thehandle mount 240, the lockingmember 220 is corresponding completely disengaged from the lockingmember receiving portion 210 of thehandle 110. As a result, thehandle 110 is able to rotate with respect to the lockingmember 220 and thehandle mount 240. For example, thehandle 110 may be rotated from the carrying position (shown inFIG. 1A ) to the stored position (shown inFIG. 1B ) in which the paddedseating portion 105 is readily accessible. - When the
handle 110 is rotated to a desired position at which thekey teeth 228 are aligned with thelarge gaps 214 in the lockingmember receiving portion 210 of thehandle 110, the lockingmember 220 may be returned to the resting state, as later described in detail. To return the lockingmember 220 to the resting state, the biasingspring 230 pushes the lockingmember 220 into the lockingmember receiving portion 210 of thehandle 110, thereby once again locking thehandle 110 with respect to the lockingmember 220 and thehandle mount 240. - To move the
conical portion 222 of the lockingmember 220 between the resting and actuated positions, the invention contemplates an actuator assembly, such as the embodiments shown inFIGS. 7A-8C and 9B-9B. - An
exemplary actuator assembly 800 is shown inFIGS. 7A-8C . For purposes of simplicity, thisactuator assembly 800 is discussed with respect to thelocking mechanism 200 on one side of thecarrier 100. It is be understood, however, that the other locking mechanism 200 (i.e., the one on the other side of the carrier) is actuated in the same manner and by thesame actuator assembly 800. -
Actuator assembly 800 can include acord 810 that terminates at cord engagement member 250 (shown in more detail inFIGS. 6A-6E ), acord connector 830, and a push-button actuator 820. Thecord 810, which may be made out of a flexible but strong material (e.g., a polymer, rope, wire, etc.), connects thecord connector 830 to thecord engagement member 250. Thecord connector 830, thecord 810, and thecord engagement member 250 may be integrally formed. Alternatively, these three components may be formed separately and then subsequently adjoined. - As shown in
FIG. 7B , aportion 822 of the push-button actuator 820 projects through thehandle 110 and is, therefore, externally accessible to a user for purposes of actuation, as hereafter described with respect toFIGS. 8A-8C . InFIGS. 8A and 8B , it can be seen that asloped surface 824 of the push-button 820 is received within aslot 832 formed in thecord connector 830. As a result, when theaccessible portion 822 of the push-button actuator 820 is pushed into the handle 110 (i.e., in the direction of arrow α shown inFIGS. 7A and 8C ), thecord connector 830 rides along the slopedsurface 824, thereby moving toward thecenter 160 of the handle 110 (i.e., in the direction of arrow β). - As the
cord connector 830 moves toward the center of thehandle 110, it pulls thecord 810 and, in turn, thecord engagement member 250 toward thecenter 160 of thehandle 110. As a result, thecord engagement member 250 moves in the direction of arrow ω, shown inFIG. 7A . Further, as thecord engagement member 250 moves in the direction of arrow ω, the lockingmember 220 moves laterally inward with respect to thecord engagement member 250. In other words, the lockingmember 220 moves in the direction of arrow β (as shown inFIG. 7A ) and is, therefore, forced into the actuated state, previously discussed with respect toFIGS. 6D and 6E . - To return the locking
member 220 to the resting state shown inFIGS. 6B and 6C , the user releases the push-button 820. When the push-button 820 is released, the biasingspring 230 forces the lockingmember 220 laterally outward (i.e., in the direction of arrow φ inFIG. 7A ), thereby forcing thecord engagement member 250 to move downward (i.e., in the direction of arrow σ), which, in turn, pulls thecord 810 away from thecenter 160 of the handle 110 (i.e., in the direction of arrow η). As thecord 810 is pulled away from thecenter 160 of thehandle 110, thecord connector 830 returns to the state shown inFIGS. 8A and 8B . As a result, the push-button actuator 820 is pushed back (i.e., in direction of arrow γ) into the position shown inFIG. 7A . The push-button 820 can be actuated and released repeatedly. - Another
actuator assembly 900 is shown inFIGS. 9A and 9B . Theactuator assembly 900 includes aslide actuator 920, tworacks cords 810 and thecord engagement members 250 function in the same manner as previously described with respect to the push-button actuator assembly 820. Accordingly, a discussion of thecords 810 and thecord engagement members 250 with respect to thisassembly 900 is omitted. - The
slide actuator 920, like the push-button actuator 820, is provided in thecenter 160 of thehandle 110. Theslide actuator 920 is fixedly connected to afront rack 922 that, in turn, is fixedly connected to acord 810A that extends to a cord engagement member 250 (not shown inFIGS. 9A and 9B ), as previously described. - The
front rack 922 includes a plurality ofrecesses 923 that are sized to receiveteeth 942 that extend around thepinion 940. Similar to thefront rack 922, therear rack 924 also includes a plurality ofrecess 925 that are sized to receive theteeth 942 of thepinion 940. Moreover, therear rack 924 is similarly fixedly connected to theother cord 810B. - To actuate the
slide actuator assembly 900, atab 930 projecting from theslide actuator 920 can be pushed in the direction of the horizontal portion of thehandle 110, i.e., in the direction of arrow β. When thetab 930 is pushed, the front rack 930 (and thecord 810A attached thereto) likewise is moved in the direction of arrow β. As the axis of rotation R of thepinion 940 is fixed, when thefront rack 922 moves in the direction of arrow β, therecesses 923, which are engaged with theteeth 942 of thepinion 940, cause thepinion 940 to rotate about its axis of rotation R. In turn, the rotation of thepinion 940 drives theteeth 942 into therecess 925 of therear rack 924, thereby causing the rear rack 924 (and thecord 810B attached thereto) to move in the direction of arrow η. As a result, bothcords center 160 of thehandle 110 in a manner similar to that previously described with respect to the push-button actuator assembly 800. Moreover, as a result of the movement of thecords center 160 of the handle, theactuator assembly 900 goes from a resting state shown inFIG. 9A to the actuated state shown inFIG. 9B . - To return to the resting state of
FIG. 9A , the user merely needs to release thetab 930. As a result, the biasing springs 230 will push their associated lockingmembers 220 into the associatedtriangular slots 252 of thecord engagement member 250, thereby causing thecords center 160 of thehandle 110. In turn, theslide 920 will be returned to its original state (i.e., the resting state shown inFIG. 9A ) by a reverse rotation of thepinion 940. - Other actuation assembly mechanisms are contemplated. For example, instead of a push-
button assembly 800 or aslide assembly 900, a twisting or rotating mechanism could be used. The moving members 114 of the embodiments shown in FIGS. 3A and 3B of U.S. Pat. No. 6,068,284, which is incorporated herein by reference in its entirety, are two examples of twisting or rotating members that could be used in a one-hand actuation assembly according to the present invention. - Although the actuators of the above-described actuator assemblies are located at the center of the handle, it will be understood that, in other embodiments, the actuator can be located elsewhere on the handle, doe example, at either end of the handle or at a location intermediate the ends of the handle.
- It will be understood that the
carrier 100 can be used in a variety of vehicles, including but not limited to cars, trucks, buses, and airplanes. Moreover, the adjustable handle is easily operable and may automatically return to a locked position upon rotation of the handle to a selected position. In addition, because the locking member can engage the adjustable handle over a large surface area, preferably over its entire circumference (i.e., 360 degrees), the adjustable handle assembly may be able to withstand greater forces without failure. - The embodiments set forth herein were for purposes of illustration. This description, however, should not be deemed to be a limitation on the scope of the invention. Various modifications, adaptations, and alternatives may occur to one skilled in the art, without departing from the claimed inventive concept. The true scope and spirit of the invention are indicated by the following claims.
