Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
156 words
A foldable retainer device having a pair of clamping members pivotably connected to distal ends of an elongate base frame fixed on a mother board, and a folding mechanism having matingly engaged pivots and pivot holes respectively formed in the base frame and the clamping member for pivotal movement of each clamping member with respect to the base frame and a first positioning unit having a protrusion portion around each pivot and groove portion defined around each pivot hole for pivotably receiving the protrusion portion and retaining each clamping member at different angles with respect to the base frame; wherein the protrusion portion around the pivot has a plurality of digits extending outward from at least a quarter of a periphery thereof and the groove around the pivot hole has a contacting tongue extending therefrom for abutting with the digits in order to retain the clamping member at different angles with respect to the base frame.
Claim 2
Dependent Claim
156 words
A foldable retainer device having a pair of clamping members pivotably connected to distal ends of an elongate base frame fixed on a mother board, and a folding mechanism having matingly engaged pivots and pivot holes respectively formed in the base frame and the clamping member for pivotal movement of each clamping member with respect to the base frame and a first positioning unit having a protrusion portion around each pivot and groove portion defined around each pivot hole for pivotably receiving the protrusion portion and retaining each clamping member at different angles with respect to the base frame; wherein the protrusion portion around the pivot has a plurality of digits extending outward from at least a quarter of a periphery thereof and the groove around the pivot hole has a contacting tongue extending therefrom for abutting with the digits in order to retain the clamping member at different angles with respect to the base frame.
Claim 3
Dependent Claim
46 words
The foldable retainer device as claimed in claim 1, wherein at least two of the digits are angled with respect to the pivot for providing a ninety degree difference therebetween thus the clamping member is operative to be either perpendicular or parallel to the base frame.
Claim 4
Dependent Claim
29 words
The foldable retainer device as claimed in claim 2, wherein the pivot has a slanted top face tapering upward for reception by the pivot hole of the clamping member.
Claim 5
Dependent Claim
40 words
The foldable retainer device as claimed in claim 3 further comprising a curved slot formed near the pivot hole for providing a tolerance space which prevents the clamping member from breaking after repeated rotations with respect to the base frame.
Claim 6
Dependent Claim
54 words
The foldable retainer device as claimed in claim 4, wherein one of the plurality of digits extending from the protrusion portion can abut against the tongue of the clamping member thereby preventing the clamping member from moving beyond a horizontal level when the clamping member is folded to be parallel to the base frame.
Claim 7
Dependent Claim
82 words
The foldable retainer device as claimed in claim 5, wherein the base frame is a rectangular closure having two parallel longitudinal walls connected to two lateral walls, two intermediate walls formed adjacent to two sides of each lateral wall and having the pivot extending therefrom, and a slit defined in the connection portion of the side wall and the intermediate wall in order to provide a tolerance space for the intermediate wall during configuration of the clamping member and the curved wall.
Claim 8
Dependent Claim
67 words
The foldable retainer device as claimed in claim 6 further comprising a second positioning unit having a protrusion plate extending upward from an upper edge of the lateral wall of the base frame and a groove defined in an inner surface of the clamping member for receiving the protrusion plate thereby preventing the clamping member from being outwardly folded beyond a position perpendicular to the base frame.
Claim 9
Dependent Claim
105 words
The foldable retainer device as claimed in claim 7, wherein a side receptacle extends from each intermediate wall for receiving a collar member therein, each side receptacle having an upper layer and a lower layer spaced from each other a distance equal to the height of the longitudinal wall, an upper hole defined in the upper layer from which a cutout diverges, and a lower hole defined in the lower layer substantially in alignment with the upper hole, whereby the collar member is forcibly inserted into the upper hole via the cutout and the bottom thereof is seated on a periphery of the lower hole.
Claim 10
Dependent Claim
43 words
The foldable retainer device as claimed in claim 8, wherein each clamping member is substantially a U-shaped structure having a base and two side walls extending upright from two sides thereof thus defining a card recess therebetween for reception of a modularized card.
Claim 11
Dependent Claim
102 words
A foldable retainer device having a pair of clamping members pivotably connected to distal ends of an elongate base frame fixed on a mother board, and a folding mechanism having matingly engaged pivots and pivot holes respectively formed in the base frame and the clamping member for pivotal movement of each clamping member with respect to the base frame and a first positioning unit having a protrusion portion around each pivot and groove portion defined around each pivot hole for pivotably receiving the protrusion portion and retaining each clamping member at least at three different angles with respect to the base frame.
Claim 12
Dependent Claim
102 words
A foldable retainer device having a pair of clamping members pivotably connected to distal ends of an elongate base frame fixed on a mother board, and a folding mechanism having matingly engaged pivots and pivot holes respectively formed in the base frame and the clamping member for pivotal movement of each clamping member with respect to the base frame and a first positioning unit having a protrusion portion around each pivot and groove portion defined around each pivot hole for pivotably receiving the protrusion portion and retaining each clamping member at least at three different angles with respect to the base frame.
