The first and second supporting apparatuses each have a respective: vertically-disposed member; horizontally-disposed supporting member; and locking member coupled to the vertically-disposed member. The locking member is disposed beneath a lower surface of the horizontally-disposed supporting member. The corner latching apparatus has a corner shape and comprises a first horizontally-disposed latching arm oriented in a first direction and adapted to engage with the locking member of the first supporting apparatus. The corner latching apparatus comprises a second horizontally-disposed latching arm oriented in a second direction and a stabilizing resilient member disposed beneath a lower surface of each of the first and second horizontally-disposed latching arms, at least a portion of the stabilizing resilient member adapted to compress against an upper surface of a curtain wall member. ## Claims ### Claim 1 A curtain wall system, comprising: a first curtain wall member supporting apparatus and a second curtain wall member supporting apparatus each having a respective: vertically-disposed member;

and a corner curtain wall member latching apparatus having a corner shape and comprising: a first horizontally-disposed latching arm oriented in a first direction and adapted to engage with the locking member of the first curtain wall member supporting apparatus; a second horizontally-disposed latching arm oriented in a second direction; and a stabilizing resilient member disposed beneath a lower surface of each of the first and second horizontally-disposed latching arms, at least a portion of the stabilizing resilient member adapted to compress against an upper surface of a curtain wall member. ### Claim 2 (depends on 1) The system of claim 1, wherein the corner curtain wall member latching apparatus further comprises a latch at a first end of each of the first and second horizontally-disposed latching arms, the latch of the first horizontally-disposed latching arm adapted to slide into the locking member of the first curtain wall member supporting apparatus. ### Claim 3 (depends on 2) The system of claim 2, wherein the latch of the second horizontally-disposed latching arm is adapted to engage with the locking member of the second curtain wall member supporting apparatus. ### Claim 4 (depends on 2) The system of claim 2, wherein the corner curtain wall member latching apparatus further comprises: a vertically-disposed locating member extending from the lower surface of each of the first and second horizontally-disposed latching arms; and a vertically-disposed retaining member, wherein the vertically disposed retaining member: extends from the vertically-disposed locating member of the first horizontally-disposed latching arm; extends partially along the vertically-disposed locating member of the first horizontally-disposed latching arm; and is adapted to engage with a notch in the curtain wall member. ### Claim 5 (depends on 4) The system of claim 4, wherein the stabilizing resilient member is located between the vertically-disposed locating member and the latch of each of the first and second horizontally-disposed latching arms. ### Claim 6 (depends on 1) The system of claim 1, wherein the corner curtain wall member latching apparatus further comprises a vertically-disposed locating member extending from a second end of each of the first and second horizontally-disposed latching arms. ### Claim 7 (depends on 1) The system of claim 1, wherein the corner shape of the corner curtain wall member latching apparatus forms a 90 degree angle. ### Claim 8 A curtain wall system, comprising: a first curtain wall member supporting apparatus and a second curtain wall member supporting apparatus; and a corner curtain wall member latching apparatus having a corner shape, comprising: a first horizontally-disposed latching arm oriented in a first direction and adapted to engage with the first curtain wall member supporting apparatus; a second horizontally-disposed latching arm oriented in a second direction; and a stabilizing resilient member disposed beneath a lower surface of each of the first and second horizontally-disposed latching arms, at least a portion of the stabilizing resilient member adapted to compress against an upper surface of a curtain wall member. ### Claim 9 (depends on 8) The system of claim 8, wherein the first horizontally-disposed latching arm of the corner curtain wall member latching apparatus is adapted to slide into a locking member of the first curtain wall member supporting apparatus. ### Claim 10 (depends on 8) The system of claim 8, wherein the second horizontally-disposed latching arm of the corner curtain wall member latching apparatus is adapted to rotationally engage with a locking member of the second curtain wall member supporting apparatus. ### Claim 11 (depends on 8) The system of claim 8, wherein the corner curtain wall member latching apparatus further comprises a downward-extending vertically-disposed retaining member adapted to partially engage with a notch in the curtain wall member. ### Claim 12 A method, comprising: engaging a corner curtain wall member latching apparatus with a locking member of a first curtain wall member supporting apparatus, wherein the corner curtain wall member latching apparatus has a corner shape and comprises a first horizontally-disposed latching arm oriented in a first direction, a second horizontally-disposed latching arm oriented in a second direction, and a stabilizing resilient member, the stabilizing resilient member disposed beneath a lower surface of each of the first and second horizontally-disposed latching arms; and compressing at least a portion of the stabilizing resilient member of the corner curtain wall member latching apparatus against an upper surface of a first curtain wall member. ### Claim 13 (depends on 12) The method of claim 12, further comprising sliding a latch of the first horizontally-disposed latching arm of the corner curtain wall member latching apparatus into the locking member of the first curtain wall member supporting apparatus, wherein the locking member is disposed beneath a lower surface of a horizontally-disposed supporting member of the first curtain wall member supporting apparatus. ### Claim 14 (depends on 12) The method of claim 12, further comprising rotationally engaging a latch of the second horizontally-disposed latching arm of the corner curtain wall member latching apparatus with a locking member of a second curtain wall member supporting apparatus, wherein the locking member of the second curtain wall member supporting apparatus is disposed beneath a lower surface of a horizontally-disposed supporting member of the second curtain wall member supporting apparatus. ### Claim 15 (depends on 13) The method of claim 13, further comprising engaging a downward-extending vertically-disposed retaining member of the corner curtain wall member latching apparatus with the first curtain wall member prior to sliding the latch of the first horizontally-disposed latching arm into the locking member of the first curtain wall member supporting apparatus. ### Claim 16 (depends on 14) The method of claim 14, further comprising engaging a downward-extending vertically-disposed retaining member of the corner curtain wall member latching apparatus with the first curtain wall member prior to rotationally engaging the latch of the second horizontally-disposed latching arm into the locking member of the second curtain wall member supporting apparatus. ### Claim 17 (depends on 12) The method of claim 12, further comprising compressing at least a portion of the stabilizing resilient member of the corner curtain wall member latching apparatus against an upper surface of a second curtain wall member after compressing the at least a portion of the stabilizing resilient member against the upper surface of the first curtain wall member. ### Claim 18 (depends on 12) The method of claim 12, the corner curtain wall member latching apparatus further comprising: a vertically-disposed locating member extending downward from a lower surface of each of the first and second horizontally-disposed latching arms; and a latch at an end of each of the first and second horizontally-disposed latching arms, wherein the stabilizing resilient member is located between the downward-extending vertically-disposed locating member and the latch of each of the first and second horizontally-disposed latching arms. ### Claim 19 (depends on 12) The method of claim 12, wherein the corner curtain wall member latching apparatus further comprises a vertically-disposed locating member extending upward from an end of each of the first and second horizontally-disposed latching arms. ### Claim 20 (depends on 12) The method of claim 12, wherein the corner shape of the corner curtain wall member latching apparatus forms a 90 degree angle.
