The receiving channel is mounted to a side of a door frame associated with a closed configuration of the folding door. The locking clip is mounted to the leading edge of the folding door. The locking clip includes sides that extend past sides of the leading edge of the folding door so as to create a ledge on each side thereof. The receiving channel includes cleats on inner walls thereof. The cleats engage the ledges to secure the locking clip within the receiving channel in a closed configuration. The locking clip may be mounted to a center of the leading edge. The receiving channel may traverse substantially the height of the door frame. ## Claims ### Claim 1 A folding door system comprising: a plurality of panels, wherein adjacent pairs of the plurality of panels are pivotally connected to one another in order to enable the plurality of panels to fold against one another when pushed in a first direction and to extend from each other when pulled in a second direction, wherein the plurality of panels pivotally connected together is a folding door; a connection means to pivotally secure a fixed edge of the folding door to a first side of a door frame; a plurality of wheel assemblies, wherein the wheel assemblies are mounted to an upper edge of the panels; a track mounted to an upper edge of a door frame, wherein the track is to receive the wheel assemblies to enable the folding door to move back and forth from an open configuration to a closed configuration; a receiving channel mounted to a second side of the door frame, wherein the receiving channel is to receive a leading edge of the folding door when the folding door is in a closed configuration, wherein the receiving channel includes cleats on inner walls thereof; and a locking clip mounted to the leading edge of the folding door, wherein the locking clip includes a front face and side walls, wherein the front face abuts a front face of the leading edge and the side walls abut sides of the leading edge, wherein edges are formed along the sides of the leading edge at points where side walls of the locking clip end, wherein the locking clip is to be received in the receiving channel when the folding door is in the closed configuration, wherein when the leading edge is within the receiving channel the edges are engaged by the cleats in order to secure the leading edge within the receiving channel. ### Claim 2 (depends on 1) The system of claim 1, wherein the locking clip is mounted to the leading edge at a position that is substantially centered along height of the leading edge. ### Claim 3 (depends on 1) The system of claim 1, wherein the locking clip is secured to the leading edge with a screw. ### Claim 4 (depends on 1) The system of claim 1, wherein the adjacent pairs of the plurality of panels are pivotally connected with hinges. ### Claim 5 (depends on 1) The system of claim 1, wherein the adjacent pairs of the plurality of panels are pivotally connected with flexible material. ### Claim 6 (depends on 1) The system of claim 1, wherein the connection means includes a mounting channel and at least one mounting clip. ### Claim 7 (depends on 6) The system of claim 6, wherein the at least one mounting clip includes cleats on outer walls thereof and the mounting channel includes cleats on inner walls thereof and the cleats engage one another when the at least one mounting clip is inserted into the mounting channel. ### Claim 8 (depends on 6) The system of claim 6, wherein the mounting channel is affixed to the folding door and the one or more mounting clips are affixed to the first side of the door frame. ### Claim 9 (depends on 6) The system of claim 6, wherein the receiving channel and the mounting channel are substantially identical components. ### Claim 10 (depends on 1) The system of claim 1, wherein the wheel assemblies include a shaft and a wheel. ### Claim 11 (depends on 10) The system of claim 10, wherein the wheel is horizontally oriented and the shaft is a screw that is threaded through the wheel and secured to an upper edge of the plurality of panels. ### Claim 12 An apparatus for securing a folding door in a closed configuration, the apparatus comprising: a folding door; a receiving channel mounted to a side of a door frame associated with a closed configuration of the folding door, wherein the receiving channel is to receive a leading edge of the folding door when the folding door is in a closed configuration, wherein the receiving channel includes cleats on inner walls thereof; and a locking clip mounted to the leading edge of the folding door, wherein the locking clip includes a front face and side walls, wherein the front face abuts a front face of the leading edge and the side walls abut sides of the leading edge, wherein edges are formed along the sides of the leading edge at points where side walls of the locking clip end, wherein the locking clip is to be received in the receiving channel when the folding door is in the closed configuration, wherein when the leading edge is within the receiving channel the edges are engaged by the cleats in order to secure the leading edge within the receiving channel. ### Claim 13 (depends on 12) The apparatus of claim 12, wherein the locking clip is mounted to the leading edge at a position that is substantially centered along height of the leading edge. ### Claim 14 (depends on 12) The apparatus of claim 12, wherein the locking clip is secured to the leading edge with a screw. ### Claim 15 (depends on 12) The apparatus of claim 12, wherein a transition from the front face to the side walls has a rounded profile to enable a smooth entry into the receiving channel. ### Claim 16 (depends on 12) The apparatus of claim 12, wherein the side walls are tapered inward to enable the leading edge to be removed from the receiving channel. ### Claim 17 An apparatus for securing a folding door in a closed configuration, the apparatus comprising: a locking clip configured to be mounted to a leading edge of a folding door, wherein the locking clip includes a front face and side walls, wherein the front face is configured to abut a front face of the leading edge and the side walls are configured to abut sides of the leading edge, wherein edges are formed along the sides of the leading edge at points where side walls of the locking clip end; and a receiving channel mounted to a side of a door frame, wherein the receiving channel is configured to receive the leading edge of the folding door when the folding door is in a closed configuration, wherein the receiving channel includes cleats on inner walls thereof, wherein the receiving channel is configured such that when the leading edge is within the receiving channel the edges are engaged by the cleats in order to secure the leading edge within the receiving channel. ### Claim 18 (depends on 17) The apparatus of claim 17, wherein the locking clip is configured to be mounted to the leading edge at a position that is substantially centered along height of the leading edge. ### Claim 19 (depends on 17) The apparatus of claim 17, wherein a transition from the front face to the side walls has a rounded profile to enable a smooth entry into the receiving channel. ### Claim 20 (depends on 17) The apparatus of claim 17, wherein the side walls are tapered inward to enable the leading edge to be removed from the receiving channel.
