4-13 show the connection hub 60 in more detail. As depicted in FIG. 4 , connection hub 60 generally includes first and second arm assemblies including guide arms 62 , 102 and drive arms 74 , 114 , hub member 82 , first and second end couplings 92 , 124, a locking assembly 132, a pair of guide pins 156 and a locking pin 164. In the exemplary embodiment, a first locking assembly (e.g., guide arm 62 and drive arm 74) is coupled to the end of vertical leg portion 25, and a second locking assembly (e.g., guide arm 102 and drive arm 102) Arm 114) is coupled to the end of the vertical leg portion 35. In the exemplary embodiment, the first and second locking assemblies (and coupled with the respective vertical leg portions 25, 35) are pivotally mounted to spaced apart pivots 83, 83 provided on the hub 82. 84 , and the central guide tube 64 , 104 of the arm assembly is axially aligned to receive the locking pin 164 .

Accordingly, the first and second lower frame supports are pivotally connected together, wherein each arm assembly is pivotally mounted to the hub (eg, pivotable about the protrusions 83, 84 of the hub 82), and wherein The arm assemblies are pivotally coupled together with locking pins 164 extending through their respective conduits 64 , 104 .

In the exemplary embodiment, first and second end couplings 92 , 124 are provided for coupling engagement with arm extensions 47 , 55 of upper support frame 40 . As shown in FIG. 4, the first and second end couplings 92, 124 include pivot guides 93, 125, drive receivers 95, 127 and end receivers 96, 96 for receiving the ends of arm extensions. 129. In the exemplary embodiment, pivot conduits 93 , 125 are axially aligned with each other and further with central conduit 85 formed through hub 82 . Drive receivers 95 , 127 are generally spaced a distance from their respective pivot guides 93 , 125 and are aligned with a pair of radial or curved slots 86 , 87 formed through hub 82 . Thus, pivotal movement of the end couplings 92 , 124 causes the drive receivers 95 , 127 to follow the path of their respective curved slots 86 , 87 . Thus, due to the pivotal coupling of the end couplings 92, 124 to the central guide tube 85 of the hub 82, the guide pin 156 extends through each respective drive receiver 95, 127 and curved slot 86, 87, and further extends Intermediate drive conduits 65, 76, 105, 116 pass through the pivotally coupled arm assemblies. Thus, the arm assembly pivotally connects together the first and second lower support frame portions 20, 30 which are further passed through the drive receiver 95, 127, through the curved groove 86, 87 and through the extension of the middle drive guide tube 65, 76, 105, 116 of the arm assembly to connect with the end coupling 92, 124, so that the lower frame support 16 or the upper frame support Pivotal movement of either member 40 results in substantially simultaneous pivotal movement of the other of lower frame support 16 or upper frame support 40 .

In the exemplary embodiment, the locking assembly 132 includes a locking member 133 that includes spaced apart channels 134, 135 for movably mounting to the arm member, such as generally proximal to its pivot, and through which the Overlock assembly 132 forms central slot 137 for receiving a portion of locking pin 164 to constrain movement of locking pin 164 to a defined path. For example, as depicted in FIGS. 7-8 , a pin 180 extends through each slot 134 , 135 , and further extends through each arm assembly to engage the protrusion 83 , 84 . In the exemplary embodiment, pin 180 secures locking mechanism 132 and arm assemblies 61, 101 to hub 82, but provides at least some clearance so that locking member 133 can move between a locked position and an unlocked position ( See Figure 7-8). Typically, adjacent locking assembly 132 is an actuation member or push button 144 that is movable or actuatable such that its movement or actuation affects the position of locking assembly 132 (eg, from a locked position to an unlocked position). In the illustrated embodiment, connection hub 60 is unlocked by actuation of button 144 to allow pivotal movement of lower frame support 16 and upper frame support 40 from the expanded configuration to the collapsed configuration. According to an exemplary embodiment, each coupling hub 60 includes a key for unlocking the locking assembly and allowing pivotal movement of the lower frame support assembly 16 and the upper frame support assembly 40 between the collapsed configuration and the expanded configuration. Push button 144 .

In the exemplary embodiment, a block or follower finger 150 extends from the bottom end of the locking member 133 for providing a sliding engagement along a cam surface 147 formed with respect to the button 144, such as to enable actuation of the button 144 to drive Follower finger 150 moves along cam surface 147 and causes movement of locking member 133 . As depicted in FIGS. 5-8 , translational movement of button 144 in a first direction results in translational movement of locking member 133 in a second direction, eg, the second direction is generally transverse to the first direction. As depicted in FIGS. 5-6 , button 144 is depressed to move within connection hub 60 in a first direction such that cam surface 147 drives follower finger 150 to cause locking member 133 to move in, for example, a second direction. movement, wherein the second direction as depicted in FIGS. 7-8 shows the locking member 133 moving from right to left. In the illustrated embodiment, when the button 144 is depressed to move in the first direction, the driven finger moves a distance D1 in the second direction. In an example embodiment, distance D1 is between about 8-18 millimeters, such as between about 12-14 millimeters according to one example embodiment. In the illustrated embodiment, the button 144 includes a finger detent 148 extending therefrom for providing removable engagement with the lower receptacle 90 of the hub 82. Thus, according to an exemplary embodiment, actuation of the button 144 results in removable engagement of the finger detent 148 and the lower receiver 90 such that the locking member 133 remains in the unlocked position.

In the exemplary embodiment, central slot 137 of locking member 133 is, for example, generally L-shaped such that the position of locking member 133 affects the allowable movement of locking pin 164, and thus ultimately lower frame support assembly 16 and upper frame support assembly. Allowable pivotal movement of member 40. 7, in the locked position, the locking assembly 132 is locked with the locking member 133, and the locking pin 164 is located within the first portion of the L-shaped slot 137, wherein the locking pin 164 is constrained to move along a generally horizontal path and is prevented from moving in a substantially horizontal path.

In the exemplary embodiment, a biasing spring 139 is provided to engage between the hub 82 and the locking member 133 to bias the locking member 133 in the locked position (see FIG. 7 ).

According to an exemplary embodiment, finger detent 148 remains removably engaged with lower receiver 90 when locking member 133 is in the unlocked position and the lower and upper support assemblies are in the expanded configuration. However, as either the lower support assembly 16 or the upper support assembly 40 retracts, the locking pin 164 begins to move up the slot 137 and forces the locking member 133 in a direction generally opposite the second direction (eg, left to right). Move back at least partially. Accordingly, movement of the locking member 133 in a direction opposite to the second direction causes movement of the driven finger 150 along the cam surface 147, thereby causing the button 144 to spread outward such that the finger detent 148 engages the lower receiver 90. Detached and reversed to a neutral position.

According to an exemplary embodiment, the portion of the slot 137 may be supported by one or more supports, such as a plate or pad 136 shaped and sized to conform to the contour of the portion of the slot 137 . In the illustrated embodiment, plate 136 is positioned to provide support for slot 137 when the locking mechanism is in the locked position. For example, since a user may attempt to retract the frame 12 with the locking member 133 in the locked position, the plate 136 provides additional support and structural integrity to the groove 137, e.g. Shrinking the frame 12 will not damage the slot 137 .
