A structural corner reinforcement for strengthening frames includes at least a first segment and a second segment of frame bar, each formed into a desired profile and each having a hollow interior portion, a reinforcing channel having a first leg and a second leg arranged at an angle to the first leg, with ends of the channel securing first and second extensions to extend the first and second legs, respectively, at least one of (i) a portion of the first extension of the reinforcing channel being inserted through a first end of the first segment of the frame bar into and substantially spaced from surfaces of the hollow interior portion of the first segment and (ii) a portion of the second extension of the reinforcing channel being inserted through a first end of the second segment of the frame bar into and substantially spaced from surfaces of the hollow interior portion of the second segment, and a rigid reinforcing and structural material, formed from a foamed chemical, inside at least one of (i) the hollow interior portion of the first segment for securing the inserted portion of the first extension of the reinforcing channel therewithin and (ii) the hollow interior portion of the second segment for securing the inserted portion of the second extension of the reinforcing channel therewithin.

Structural corner reinforcement, a frame including such a reinforcement

A corner reinforcement for use in strengthening screen frames, for example, includes at least a first segment and a second segment of screen bar, each formed into a desired profile and each having a hollow interior portion, a reinforcing channel and a rigid reinforcing and structural material. The reinforcing channel has a first leg and a second leg arranged at approximately ninety degrees to the first leg with ends of the channel securing first and second extensions to extend the first and second legs, respectively. At least a portion of (i) the first extension of the channel is inserted through a first end of the first segment of the screen bar into and substantially spaced from surfaces of the hollow interior portion thereof and (ii) the second extension is inserted through a first end of the second segment of the screen bar into and substantially spaced from surfaces of the hollow portion thereof. The rigid reinforcing and structural material, formed from a foamed chemical, is inside at least one of (i) the hollow interior portion of the first segment for securing the inserted portion of the first extension of the reinforcing channel therewithin and (ii) the hollow interior portion of the second segment for securing the inserted portion of the second extension of the reinforcing channel therewithin. Also disclosed is a screen frame including such corner reinforcements, as well as methods for making these products.

The rigid reinforcing and structural material, formed from a foamed chemical, is inside at least one of (i) the hollow interior portion of the first segment for securing the inserted portion of the first leg of the reinforcing channel therewithin and (ii) the hollow interior portion of the second segment for securing the inserted portion of the second leg of the reinforcing channel therewithin. A wheel mechanism may be secured to one of the first and second legs of the reinforcing channel and encased in a decorative cover. Also disclosed is a screen frame including such corner reinforcements, as well as methods for making these products.

Apparatus for inserting conventional pile weatherstripping, for example, into a T-slot in an object includes a member which slides longitudinally relative to the object along the T-slot and is guided so as to remain fixed laterally with respect to the object during relative longitudinal movement. A guideway for the weatherstrip extends through the member and is inclined downwardly towards an exit adjacent the T-slot. The guideway also is angled relative to the T-slot to hold the backing of the pile weatherstrip at an angle at which one of the flanges of the backing can move into the groove of the T-slot through the T-slot opening. A finger, presser wheel or the like located upstream from the guideway exit extends into the T-slot through the T-slot opening and engages with the other of the flanges of the pile weatherstrip to move the other of the flanges into the T-slot groove through the T-slot opening.
