Oct. 28, 1958 w; E. BUNKER WEATHERSTRIP MEANS FOR A sunmc DOOR Filed Oct. 1. 1954 INVENTOR. v mum/14E fiu/vzze Arraen/gk 1 atet fiice 2,857,633 Patented Oct. 28, 1958 WEATHERSTRIP MEANS FORA: SLIDING nooR William'E. Bunker, West Covina, Califi, assignor to Arcadia Metal Products, Inc., Arcadia, cane, a corporation of California Application October 1,1954, Serial No.'459,764 '10 Claims. (Cl. 20-19 This invention relates to Weatherstrip means and more particularly to Weatherstrip means for sliding panels or doors.

Weatherstripping of exterior sliding doors presents a difiicultproblem. Such a sliding door must be mounted for relatively easy sliding movement and is usually provided with wheels enclosed within a bottom rail member of the door and engaging an upstanding track provided on a door frame member or sill. Adequate space or clearance is necessarily providedbetween the track and the interior walls of the rail member to permit easy movement of the door. This space, which extends the length of the door, also provides a passageway for air, dust, dirt and the like.

Sliding doors may be adjustable so that vertical rail members of the door maybe accuratelyplumbed or arranged to properly meet with cooperable jamb members of a door frame or with a vertical rail member of an adjacent panel. In adjustment of the door to the door frame, the top and bottom horizontal rail members of the door may not be parallel to the adjacent door frame members' Heretofore, Weatherstrip means have been fixed in-various manner and form to a horizontal rail of a sliding door by permanent screws, bolts and the like. When such a sliding door is mounted 'in a door frame in the field, such Weatherstripping on a rail member for the door may not properly engage a track or other opposed face on a door frame member. Thus the Weatherstrip means is rendered virtually ineffective for a substantial portion of its length and'does not effectively serve its purpose.

The primary purpose of this invention is to provide a novel Weatherstrip means for sliding doors mounted in such a manner that upon adjustment of the door to a door frame, the eatherstrip means is simultaneously and automatically adjusted so as to remain in effective.

weathersealing relationship with a cooperable portion of the door frame.

An object of this invention is to disclose and provide a Weatherstrip means for a sliding door quickly and readily adjusted into proper position with respect to the cooperative door frame member when the door is adjusted to the door frame.

Another object of this invention is to disclose and provide a novel manner of floatingly, adjustably mounting an elongated Weatherstrip means in a door rail member.

A further object of this invention is to disclose and provide a Weatherstrip means for use in a bottom rail member of a sliding door and which will automatically be adjusted into proper relationship with a track on the sill of the door frame upon adjustment of the door to the door frame.

A further object of this invention is to disclose and provide a mounting means for such a Weatherstrip means which releasably interengages therewith for automatic or facile adjustment of the Weatherstrip means.

A still further object of this invention is to disclose and provide a'weatherstrip means wherein means nor- :2 mallycarried'bya r'ail member-of the door'cooperably engages and then released so that-'the-side walland securing elements 41 are snapped against the walls of the railrnembcr. 3 The clips are inserted at selected spaced intervals.

A still further 'object 'of this invention isto disclose and provide a Weatherstrip means wherein means normally carried by a rail member of the door cooperably engages the Weatherstrip means for properly positioning the Weatherstrip means with respect to the associated door frame member.

Still another object of this invention is to disclose and provide a Weatherstrip means which is readily replaceable when worn.

- Generally speaking, this "invention contemplates a Weatherstrip means for a sliding door wherein a door bottom rail member and a door frame member or sill in relatively movable relation are provided with opposed longitudinally extending'faces defining a longitudinally extending space-t0 be sealed. The-Weatherstrip means of this invention isfloatingly'mount'ed on'an inner face of the door rail member and is provided with a sealing pile portion extending to an opposed face on the door frame member for weather sealing contact therewith. The Weatherstrip means'includes longitudinally extending'spaced parallel ridges which cooperably and releasably interlock and interengage' with a projection on an outwardly'biased tongue provided on each of a plurality of longitudinally spaced spring'clips. The spring clips provide mounting means for" the Weatherstrip means and are sprung within'the bott'omrail member of the door. The

top edge of the Weatherstrip means is contacted by the lower extremity of a sheave housing carried within the bottom rail and thus relative displacement of the bottom rail with 'respect tothe door frame member does not disturb the sealing relation of the Weatherstrip means with the opposed face'on'the track of the door frame member when thedoor is adjusted within the door frame.

Other objects and advantages of this invention will be readily apparent from the following description of the drawings in which an exemplary embodiment of this invention is shown.

In the drawings: 7

Fig. 1 is a fragmentary side view, partly in section, of a bottom corner of a liding door provided with weatherstrip means 'of this invention.

Fig. 2 is a transverse vertical section taken in the plane indicated by line IIiI of Fig. 1.

Fig.3 is an enlarged fragmentary view of the lower portion of Fig. 2, the sheave and wheel assembly being shown in phantom lines.

Fig. 4 is an end view of a spring clip for mountingthe Weatherstrip means.

Fig. 5 is a perspective view of the spring clip shown in Fig. 4.

In the drawings, a door frame 8 and a sliding door 9 mounted in the door frame are only fragmentarily shown. It is understood that the door frame comprises usual construction including vertical jamb members interconnected at the top by a header member. A sill 10 of the door frame may be'of any suitable form and is illustrated as being provided with an upstanding longitudinally extending rolled track 11 provided with a cap 12. The cap 12 provides an'outer vertical face 13 which is spaced from and opposed to an inner face 14 provided on an outer leg 15 of a downwardly opening U-section horizontal bottom rail member 16. The opposed faces 13 and 14 define a longitudinally extending space which is sealed by a Weatherstrip means 17 embodying this invention. I

The bottom rail member 16 of the sliding door 9, may be connected in usual manner atopposite ends to vertical rails which are interconnected by a top rail. Means for adjusting vertical rail members of the door with respect to the vertical jamb members of the door frame for proper meeting engagement may comprise an adjustable pivotally mounted sheave means 19 which may be actuated by a screw bolt 20 for field adjustment of the door to a door frame. The sheave means 19 is described and claimed in Patent No. 2,668,318. The sheave means 19 includes a sheave housing 21 enclosed and mounted within the bottom rail member 16. Within the sheave housing is carried a wheel 22 for rolling engagement with the track 11. It should be noted that at least the outer side wall of the sheave housing extends downwardly below the axis of the wheel to a lowermost extremity indicated at 23.

The Weatherstrip means 17 comprises an elongated rigid metal member 24 and a corresponding elongated fabric means 25 secured to said rigid member 24 and provided with a sealing portion 26 extending to and contacting the outer face 13 of the track cap 12. The rigid member 24 may be made of any suitable material and includes an outwardly overfolded to margin 27 which receives the top margin of the fabric means 25 and which may be crimped thereagainst for tightly securing the top margin of the fabric means. The rigid member 24 is somewhat similarly provided with an inwardly directed overfolded bottom margin 28 which receives and secures the bottom margin 29 of the fabric means 25. The fabric means 25 extends along the outer surface of the rigid member 24, around the overfolded bottom margin 28 and then downwardly between the margin 29 and the main portion of the member 24. The overfolded margin 28 has sufficient width to provide proper backing or support for the sealing portion 26 of the fabric means.

The sealing portion 26 may be made in any suitable manner and may comprise a longitudinally extending strip of resilient relatively stiff pile elements, such as mohair or the like. The sealing portion 26 together with the bottom overfolded margin of the Weatherstrip means 17 completely closes the space between the opposed faces 13 and 14 of the track cap and the door rail member respectively. The ends of the sealing portion 26 slidably contact face 13 of the track cap. To provide effective weathertight engagement, the sealing portion 26 is maintained and held in contact with face 13 as shown in Figures 2 and 3 for the entire length of the rail member.

Means for mounting the Weatherstrip means 17, so that the sealing portion 26 maintains the desired contact with the track cap, includes a plurality of parallel longitudinally extending spaced inwardly directed ridges 30 provided on rigid member 24 above the bottom overfolded margin 28. The ridges 30 define therebetween longitudinally extending valleys or grooves 31. Cooperably engageable with at least one of said ridges 30 is an outwardly directed projection 32 provided at the bottom end of an outwardly biased tongue 33 depending from one side edge of a top wall 34 of each of a plurality of spring clips generally indicated at 35. The spring clips 35 provide means for iioatingly mounting the Weatherstrip means 17 against the inner face 14 of the bottom rail member.

The spring clip 35 includes a side wall 36 outwardly biased and provided with an outwardly directed lip 37 adapted to seat as at 39 against the bottom edge of an inner leg 38 of the bottom rail member 16. On opposite sides of tongue 33 and integral with top wall 34 are provided depending outwardly biased secured elements 40, each securing element 40 being provided at bottom corners thereof with outwardly directed sharp points 41. The points 41 engage the inner face 14 of the rail member and precent slippage of the spring clip with respect thereto.

It assembly with the bottom rail member, spring clips 35 are compressed as by squeezing, inserted into the rail member until lip 37 contacts the bottom edge of the rail,

and then released so that the side wall and securing elements 41 are snapped against the walls of the rail member. The clips are inserted at selected spaced intervals.

iii)

The Weatherstrip means 17 may then be readily inserted within the bottom rail 16 and securely held against the inner face 14 of the outer leg 15 thereof by the tongues 33 of the spring clips. It will be noted that each projection 32 is formed with an outwardly flaring face 43 which facilitates springing back of the tongue 33 when the top edge of the Weatherstrip means 17 is inserted into the bottom rail member. The Weatherstrip means is selectively positioned so that the sealing portion 26 will properly engage the track cap and extend in parallel relation therewith, such selective positioning being afforded by the releasable interlocking slipping engagement of projections 32 with the ridges 30 on the Weatherstrip means. In normal assembled position, the top edge of the Weatherstrip means 17 contacts the lowermost extremity 23 of the sheave housing. This contact serves to properly position the Weatherstrip means with respect to the track because of the fixed relationship between the track and the axis of rotation of the wheel.

When the door is adjusted to a door frame in the field and the sheave housing is pivoted by actuation of the screw bolt 20, the bottom rail member is displaced vertically with respect to the track. Since the top edge of the Weatherstrip means 17 has contact with the sheave housing at 23, the Weatherstrip means will be prevented by the sheave housing from moving therewith. Thus as the sheave is adjusted, the Weatherstrip means is simultaneously and automatically adjusted or held in effective sealing relation with the track. It will be noted that the clips 35 move with the bottom rail and biased tongues 33 of clips adjacent to the sheave housing will disengage from one ridge 30 and engage an adjacent ridge 30. Re1ative movement or slippage between the clips and the rail is prevented during this adjustment by the sharp points 41 on each spring clip which tend to dig into the metal of the bottom rail member. Relative movement is afforded between the Weatherstrip means 17 and the face 14 on the bottom rail member during such adjustment particularly immediately adjacent the sheave. Relative movement of the opposite end of the Weatherstrip means is insufiicient to cause change in engagement of the projections 32 with ridges 30. Thus the Weatherstrip means 17 is held and maintained in proper relation with the track cap.

It will thus be understood by those skilled in the art that an adjustable Weatherstrip means has been provided for a sliding door wherein the Weatherstrip means may be readily, properly positioned and maintained with respect to the door frame member with which it cooperates for providing effective sealing contact. Since the Weatherstrip means is held and maintained in position by a plurality of spring clip means, it may be readily removed and re placed when worn by merely pulling the Weatherstrip means downwardly and out of the bottom rail member. The floating suspension of the Weatherstrip means by the spring clips also provides easy application of the means of this invention to old door constructions.

It is understood that various modifications of thisinvention may be made which come within the spirit of this invention. Although the exemplary embodiment has been described with respect to Weatherstripping of a bottom rail member and the sill of a door frame, it is understood that the weatherstrip means may be mounted and may be employed between any two members arranged in relatively movable relation with respect to each other.

All changes and modifications coming within the scope of the appended claims are embraced thereby.
