[0202] Detachable handle and detachable smart phone shelf may be designed for all embodiments made with plastic injection molding. Claws 8005e, 8010d, 8010e and 8007e shown in FIG. 83A engage with the slots 8006i, 8006f, 8006k and 8006b.

[0203] The preferred length of the handle is approximately 700 mm, but it could be shorter or longer. The link plates in the preferred, first alternate and second alternate embodiments may have multiple living hinges or use flexible material such as fabric.

[0204] Referring to FIGS. 84, a collapsible stool 9000 is disclosed. The collapsible stool includes a plurality of hinges 9010. The collapsible stool also includes a plurality of supporting members 9002, 9003, 9004, 9005, 9006, 9007, 9008 (not shown), 9009 (not shown) etc. connected via the plurality of hinges 9010. The plurality of supporting members includes at least two top members 9002, 9003, a front member 9005, a back member 9004, a pair of right-side members 9008, 9009 (not shown) and a pair of left side members 9006, 9007. The collapsible stool also includes a long handle 9001 connected to at least two top members with a plurality of connecting members. The long handle 9001 is connected to the supporting member a long pin 9011. In reference to FIG. 84 and FIG. 85, the long handle 9001 is elongated having an outer hollow member 9001a, 9001b and inner trigger member 9001c. The outer hollow member comprises of a first outer member 9001a and a second outer member 9001b. The second outer member 9001b fits into the first outer member 9001a to form a housing to house inner trigger member 9001c. In the embodiment the outer hollow member forms a D shaped grip 9001d to move the collapsible stool from one place to another.

[0205] In another embodiment, the inner trigger member 9001c is also modified into a D shaped trigger point 9001e. In the embodiment, the trigger point 9001e may be modified into T shaped instead of D shaped. In another embodiment, the D or T shaped trigger point may be modified into wavy curves to fit in comfort with fingers of users. In another embodiment, the grip 9001d has a larger perimeter than the trigger point 9001e so that trigger point may be positioned within the grip 9001d. In one of the embodiments, the first outer member 9001a has a bigger perimeter to receive the second outer member 9001b and form a housing for the trigger member of the handle.

[0206] In one of the embodiments, the handle 9001 is long that may comprise a first top part, a middle part and a bottom part. The first top part comprises a grip and trigger point. The middle portion is hollow to house trigger member 9001c. In the embodiment, the middle portion may be provisioned for holding smart phones or tablets. In the embodiment, the bottom part of the long handle is connected to the back side of the plurality of supporting members with at least two link plates 9012, 9013. The long handle 9001 further includes at least two link plates 9012, 9013 attached to the bottom part of the trigger member 9001c of the long handle 9001 through small pin 9014. At least two link plates 9012, 9013 are coupled to each of the two top supporting members 9002, 9003 of the plurality of supporting members. The long handle further includes a pulling lever mechanism located at the bottom part of the inner trigger member of the long handle 9001 and coupled to the inner trigger member or actuating component. Moreover, the pulling lever mechanism may be configured to deploy the plurality of supporting members via the actuating component when the trigger point of the handle 9001e is pulled. In the embodiment the collapsible stool gets closed when the stool is taken/pulled through D shaped grip 9001d of handle.

[0207] In the embodiment, the handle 9001 has two types of hinge mechanisms, a first hinge mechanism is associated with the inner trigger member 9001c and a second hinge mechanism is outer hollow members 9001a, 9001b. In accordance with the invention, the first hinge mechanism is responsible for deploying the pluralities of the support members to open the stool. The first hinge mechanism comprises bottom part 9001h of the trigger member that comprises bottom hole 9001m, a first link plate 9012 having a first link plate hole 90011, a second link plate 9013 having a second link plate hole 9001k, a washer 9001n and a short pin 9014. The first hinge mechanism deploys the pluralities of the support members to open the collapsible stool when trigger point 9001e is pulled. Further, the second hinge mechanism is responsible for closing of the collapsible stool when grip 9001d, 9001f is pulled. The hinge mechanism comprises a pluralities of holes 9001i of first outer member 9001a, a pluralities of holes 9001j of the second outer member 9001b, notch 9001g of the trigger member and long pin 9011 that passes through the hinges of the two top supporting members 9002, 9003.

[0208] FIG. 86 to FIG. 87, illustrate an open collapsible stool when trigger point is pulled in accordance to embodiments of the present invention and a collapsed stool when the stool is pulled with D shaped grip 9001d, 9001f of bigger perimeter.
