Description  (OCR text may contain errors)


This invention relates to improvements in sealing. devices for doors and windows and is directed particularly to, an automatically operating device which functions upon. the closing of the, door or window to form a tight air and dust proof joint.

A principal object. of the present invention is to provide a device for sealing the joint between an edge of a door, at the top or bottom thereof and the adjacent frame or the edge of a window at either side of the sash and the adjacent frame, which functions upon the closing of the door or the window sash by. having a portion projected or shifted outwardly to tightly engage the adjacent part of the door or window frame and, operating reversely upon the opening of the door or window sash, to unseal the joint.

Another object of the invention is to provide a sealing device of the character stated wherein there is employed a fixed body which is carried by the door or window sashv and a movable body hung from. the fixed body to. swing toward and away from the same, the movable. body having a pivoted finger which contacts with the door or window frame upon the closing of the door or sash to which the body is secured, whereby to effect the movement of the shiftable body into working position.

The invention will be best understood from a consideration of the following detailed description taken. in. connection with the accompanying drawing forming a part of the specification, with the understanding, however, that the invention is not tov be understood as, limited to'the exact de tails of construction shown and described since obvious modifications will occur to a person skilled in the art.

In the drawing:

Figure 1 is a view in elevation of the outer side of the lower part of a door showin applied thereto a sealing. device constructed in accordance with the present invention.

Figure 2 is a View in perspective of the door in open position showing, in perspective, the sealing device in elevated or inoperative position.

Figure 3 is a view in front elevation of the inner side of a portion of a lower window sash showing the present invention applied thereto.

Figure is a vertical longitudinal section of the sealing device per se shOWing the sealing strip in elevated position.

Figure 5 is a vertical transverse section taken on the line 55 of Figure 4.

Referring now more particularly to the drawing Figures 1 and 2 illustrate the application of the present invention to a door wherein the door body is generally designated Hi, the frame is designated H and the door sill is designated l2.

In accordance with the present invention there is provided a unit which is adapted to be secured to the bottom or to the top of the door upon the outer side and which is generally designated l3. This unit comprises the fixed member It which is of inverted U channel form and of a length to substantially equal the width of the door to which it is attached. The channel body comprises the inner and outer wall portions or and b respectively and the narrow connecting top Wall portion 0. This body is disposed with one of the side walls againstthe side of the door and the sidewalls are connected by the riveted tubular spacer elements [5 through which screws 16 or likesecuring elements are inserted, the elements acting to maintain the required parallel spacing of the outer side wall I) with respect to the inner side wall a. The two ends of the fixed body M are open and the lower open side is disposed in relatively close parallel proximity to the adjacent transverse edge of the door'body.

Slidably positioned in the fixed body It for projection through the lower edge, is the movable sealing body or strip which is generally designated ll. This movable sealing body or strip as illustrated, is preferably of U channel form with its open side directed upwardly within the body M. However it is to be understood that the invention is not limited to this specific form for the body ll as it may be of solid construction if desired, with suitable modifications to facilitate its being mounted within the fixed body M.

The shiftable sealing body IT has pivotally connected between the spaced side walls at, one end of each of several suspension links [8, the other ends of such links being disposed in the upper part of the channel body I 4 and pivotally mounted therein as indicated at I9.

The sealing body I! is suspended by the links l8. for longitudinal swinging movement and accordingly it will be seen that. by such swinging movement the sealing body can be projected outwardly from the fixed body I 4 or retracted or withdrawn partly into the body.

The sealing body H is normally urged inwardly with respect to the channel body 14 by a spring 20 which is secured at one end in the upper part of the fixed channel body l4 while the other end is secured in the sealin body IT. This spring 20 pulls the sealing body I! toward the hinged edge of the door and upwardly away from the adjacent transverse edge of the door. This movement of the body I! under the action of the spring 20 causes the end of the body I! which is adjacent to the hinged edge of the door, to move outwardly from the fixed body [4 slightly.

Supported upon a pivot 21 which extends across between the sides d of the sealing body [1, at the end thereof adjacent to the hinged edge of the door, is a contact or presser finger 22 which extends through the adjacent open end of the body I! and to a slight distance beyond the same as shown. This finger 22 oscillates freely upon the pin 2! so that it gravitates to a downwardly slanting position of rest upon the end edge of the bottom wall of the body I! when the door is in open position.

When the door is closed the end of the finger 22 first engages the adjacent inner face of the door frame so as to impart lengthwise thrust to the body IT. This causes the body to swing across the door and outwardly with respect to the body I l so that when the door is in fully closed position the sealing body I! will be pressed against the door sill 12, if the sealing device is atthe bottom of the door, or against the underside of the top of the door frame if the sealing device is upon the top of the door. With the closing movement of the door, the finger 22 swings upwardly upon the pin 2| correspondingly as the sealing body ll shifts downwardly in an arcuate path, preventing twisting or the application of uneven pressure to the sealing body fl and also prevents marring of the adjacent face of the frame, as might occur if the end of the body l1 butted directly against the frame instead of the finger 22 with the sealing body i1 fully depressed against the adjacent frame part the finger 22 assumes a substantially horizontal position on the pin 2| with its outer end disposed in close proximity to the adjacent end edges of the fixed body M as shown in dotted outline in Figure 4.

Figure 3 illustrates how the sealing device might be applied to a window sash so as to seal the joint between the sash and the frame when the Sash is shifted to closed position. In this figure the window sash is generally designated 23 and one side of the frame is designated 24. The numeral 25 designates a portion of the frame sill. As shown the sealing unit is applied to the stile of the sash; When mounted or applied on the lower sash the finger 22 is directed downwardly so that when the window is closed it will strike the sill and effect the movement of the sealing member I! into contact with the face of the adjacent jamb. It will be readily obvious that when the device is used upon the upper sash it will be mounted upon the outer side and will be positioned to have the contact finger 22 directed upwardly to engage the under face of the horizontal top portion of the frame when the top sash is closed.

While the device embodying the present invention has been illustrated as applied to the face of a door and to the face of a stile of a window sash, such door and sash faces may be recessed,

if desired, to receive the sealing device so that the outer side of the fixed body I4 will be flush with the surface into which the device is recessed. It has been found that the best way to install the device is in a channel where it will be out of sight.

I claim:

A sealing means for a structure such as a door or window having a movable element and two right angularly related frame parts, comprising a relatively long body fixed to the movable element adjacent to and parallel with an edge thereof for movement therewith toward and away from one frame part, a relatively long sealing body, link members pivotally coupling the sealing body with the fixed body by which the sealing body is maintained in parallel relation with the fixed body, spring means connecting the fixed body with the sealing body and normally urging swinging movement of the sealing body toward the fixed body, said sealing body when drawn toward the fixed body by the spring means having the end adjacent to the said one frame part projecting beyond the adjacent end of the fixed body, and a contact finger pivoted to the sealing body adjacent to and inwardly of the said end thereof and projecting beyond the said end of the sealing body for engagement against the said one frame part upon movement of the movable element to 'closed position to effect the swinging of the sealing body against the action of said spring away from the fixed body and into sealing contact with the other frame part, the supporting pivot for said contact finger being disposed transversely of the sealing body, said contact finger normally sliding outwardly and downwardly and said sealing body including a part upon which the contact finger rests when the movable element is disposed in open position, the contact finger engaging with the said one frame part during said closing movement of said movable element to initiate the shifting of said sealing body relatively to said fixed body and toward its operative position, said contact finger swinging on its pivot support into a substantially horizontal position immediately inward of the adjacent end of the fixed body correspondingly with the continued shifting movement of the sealing body into its fully operative position, and said finger gravitating back to its normal position upon the reopening of said movable element and the retraction of said sealing body into its normal position by the action of said spring means.
