Window guard

In combination a double hung window structure and guard structure therefor, said window structure including a rectangular frame with laterally spaced vertical side members with inner and outer vertical channels with flat bottoms, a horizontal header and a horizontal sill, an upper outer rectangular sash with sides slidable engaged in the outer channels, a top edge normally engaged with the header and a bottom edge spaced about midway between the header and sill and opposing the sill, a lower inner rectangular sash with sides slidably engaged in the inner channels, a top edge about midway between the header and the sill and opposing the header and a bottom edge normally engaged with the sill, the guard structure comprising vertically spaced horizontal upper and lower rods with upper and lower edges, anchoring means at the ends of the rods engaged with the outer channels, and grating secured to and extending longitudinally of and between the rods, the upper edge of the upper rod and the lower edge of the lower rod being normally spaced from their opposing bottom edge of the upper sash and the sill predetermined limited distances, said upper edge of the upper rod engaging the lower edge of the outer sash upon downward shifting of the outer sash to stop said outer sash with its top edge in predetermined limited vertical spaced relationship from the header, the normal distance between the rods and the sill and the bottom of the outer sash is less than 8 inches and the distance between the header and the top edge of the outer sash is less than 8 inches when said outer sash is shifted down and engaged with the guard whereby the vertical extent of all unobstructed openings in the window and guard structure inhibit the free ingress and egress of a person therethrough, wherein the rods are established of telescopically engaged tubular sections and are axially extensible and include locking means between their related sections to hold the sections against relatively axial shifting, whereby the rods are extensible to urge the anchoring means at their ends into engagement in and with their related channels and said rods are locked against axial shifting when said anchoring means are engaged in and with said channels, said anchoring means includes flat stop surfaces at the ends of the rods in flat bearing engagement with the bottoms of their related channels and a plurality of sharp spike projecting longitudinally outwardly from said surface and engaged in the vertical side members, wherein said locking means includes threaded blocks carried by the inner tubular sections of the rods, bearing plates in the outer tubular sections of the rods, threaded shanks engaged through the blocks and having ends engaging the plates, operating discs on the shanks with circumferentially spaced tool engaging notches within the outer tubular sections and access openings in the sides of the outer tubular sections through which an operating tool is engaged to engage the operating discs.
