It will also be seen that the guard is formed with faces fitting the edges of the door and hinge member so as to completely close the crackbetween the 'door sections in such a manner that it is impossible for anyonesfingers to be placed be tween the door sections when the door is in folded or unfolded position.

What I claim is z I y I 1. The combination with a pair of door sections, of an L-shaped member secured to each door section, said members being provided with oppositely disposed slots, links disposed within'said slots, pintles passing through said links, two of saidlinks being provided with apertured threaded lugs and a guard strip adjustably secured to said lugs l s- I a v 2.

Thecombination witha pair of door sections, of a hinge member pivotally connect-ing said sections together, said hinge member comprising a pair of L-shaped members adapted to embracethe adjacent edges of said door sections, a pintle carried by each L shaped member, links connecting said pintles, means for connecting said links central-1y together and a guard strip carried by said links. i

4. The combination with a pair of door sections, of a hinge member connecting said door sections together, said hinge member comprising a pair of L-shape'd members embracing the adjacent edges of said door sections, said L-shaped members being provided the edge of each section, each L-shaped memher being provided wi'thoppositely disposed notches, pintle pins disposed within said 'L-shaped members, links (llSPOSECl. withinsaid notches pivotally mounted upon said pins, a bolt passing centrally through said links, a spring disposediaround said bolt having its ends engaging said L -shaped members and a guard strip disposed bet-ween said L-shaped members having a connection with said links.

6. The combination with a pairoit door sections, of a hinge member connecting said sections comprising a pair of L-shaped members adapted to embrace the adjacent edges of said door sect ons, said hinge member being connected together by links, a bolt passing centrally through said links, apertured lugs carried by two of said links, a

guard disposed betweenQsaid door sections having faces corresponding to the edges of said door sections and bolts passing through said guard and to said apertured lugs for securing said guard to the links of said hinge member. i

7 The combination with a pair of door sections, of a hinge member connecting said sections together, said hinge member comprising a pair of L-shaped members embracing the adjacent edges of said door and piv-f otally connected together by a pluralitvof links, means for securing said links centrally together and a guard disposed between said members having a connection with said links.
