(31) In this embodiment of the present invention and referring to FIGS. 3-6, the leg member 106 comprises two elongated shafts 130, i.e., an elongated inwardly and then outwardly angled shaft 130 on each longitudinal side of the leg member 106, as described herein above, a length of each of the elongated shafts 130 is the same as each other and is less than a length of the elongated rectangular supporting section 122, the elongated shafts 130 each comprising a first end 132 and a second end 134, the first end 132 and the second end 134 are oppositely located to each other, each second end 134 is configured to contact the ground 113, the second pin member 114 laterally penetrates both first ends 132, the first ends 132 being pivotally connected with the second supporting ends 128 via the second pin member 114, and the spring member 108 is disposed on the second pin member 114 and is biased in between the first end 132 and the second supporting end 128 so as to drive the leg member 106 from being positioned in the folding configuration inbetween the sides 123 of the supporting member 104/122, to the partially unfolding configuration and eventually to the fully unfolding configuration.

(32) In this embodiment of the present invention, for example, the spring member 108 is a wire torsion spring sleeved on the second pin member 114.

(33) In this embodiment of the present invention and regarding FIG. 3, the sleeve member 110 can be preferably rectangular, and can comprises a sleeve body 136, a channel 138, a first lateral hole 140 and a pair of second lateral holes 142, the sleeve body 136 comprises a first sleeve end 144 and a second sleeve end 146, the first sleeve end 144 and the second sleeve end 146 are oppositely located to each other, the channel 138 axially traverses through the sleeve body 136, the first lateral hole 140 axially traverses into the sleeve body 136 from the first sleeve end 144 and laterally traverses into the sleeve body 136, the pair of second lateral holes 142 axially traverse into the sleeve body 136 from the second sleeve end 146 and laterally traverse into the sleeve body 136, the pair of second lateral holes 142 are oppositely located to each other, the first lateral hole 140 is located in between the pair of second lateral holes 142, and the elongated rectangular supporting section 122 is inserted into the channel 138 such that the sleeve body 136 is slidably sleeved on the elongated rectangular supporting section 122. The sleeve member 110 can fit over rectangular supporting section 122 by sliding the body 136 over the, end 128 of elongated rectangular supporting section 122.

(34) In the first aspect of this embodiment of the present invention, as shown in FIG. 2, when the leg member 106 is positioned in the folding configuration, the elongated shafts 130 of the leg member 106 and a cross connection 125 therebetween are accommodated within the slot 124, the second ends 134 are adjacently located to the first supporting ends 126, the sleeve body 136 is sleeved on the elongated shafts 130 and the elongated rectangular supporting section 122, the second pin member 114 is inserted into the pair of second lateral holes 142, the sleeve body 136 rests against the second pin member 114, and the spring member 108 is compressed in between the elongated shaft 130 and the elongated supporting shaft 122.

(35) In the second aspect of this embodiment of the present invention, as shown in FIGS. 1, 4 and 5, when the leg member 106 is positioned from the folding configuration to the partially unfolding configuration, the elongated shafts 130 extend away from and are obliquely oriented to the elongated rectangular supporting section 122 via the spring member 108, and the elongated shafts 130 swing about the elongated rectangular supporting section 122 such that the second ends 134 move away from the first supporting ends 126 and the elongated shafts 130 laterally extends out of the first lateral hole 140 and rests against the sleeve body 136.

(36) In the third aspect of this embodiment of the present invention, as shown in FIG. 6, when the leg member 106 is positioned in the fully unfolding configuration, the elongated shafts 130 extend away from and are parallelly oriented to the elongated rectangular supporting section 122, the first supporting end 126, the second supporting end 128, the first end 132 and the second end 134 are serially in an align arrangement, the sleeve body 136 is sleeved on the elongated shafts 130 and the elongated rectangular supporting section 122 and rests against the second pin member 114 so as to constrain the elongated shafts 130, and the elongated rectangular supporting section 122 contacts against the limiting plate 120 via the buffer 148.

(37) Accordingly, when the leg member 106 is positioned in the fully unfolding configuration, the door stopping system will lock the position of the door. The door stopping system can be attached to a door for use in police breaching applications or for law enforcement. The door stopping system is suitable for both inward and outward opening doors. When the door is opened, the second end 134 of the leg member 106 that contacts and grips the ground or the floor provides friction so as to hold the door open when the door is moved from an open towards a closed position. The door stopping system prevents a door which has been kicked in from swinging back into the doorway. For example, the police officers do not have to worry about the door bouncing back and that way the police officers can just focus on the situation itself. It will decrease danger and increase police efficiency and will save lives.

(38) Since many modifications, variations, and changes in detail can be made to the described preferred embodiments of the invention, it is intended that all matters in the foregoing description and shown in the accompanying drawings be interpreted as illustrative and not in a limiting sense. Thus, the scope of the invention should be determined by the appended claims and their legal equivalents.
