ADJUSTABLE DOOR UNIT FOR SECTIONAL PARTITIONS Thomas V. Balch, Shaker Heights, and John A. Bohnsack, Cleveland Heights, Ohio, assignors to The E. F. Hauserman Company, Cleveland, Ohio, a corporation of Ohio Application December 2, 1930, Serial No. 499,496

11 Claims.

This invention relates to the installation of door sections in sectional building walls, and more particularly in walls of the metallic knockdown type. It is customary in the erection of metal partitions to install all panel sections and door sections at a common level determined by the highest point in the floor and this has occasioned unnecessarily large clearances under doors which occur at locations where the floor level is low. It frequently occurs that doors are installed with a minimum of clearance underneath and rugs or other floor covering are later installed making it necessary to increase the clearance under the door in order that it may 5 swing over the rug. It is highly desirable that it be possible to readily adjust the clearance under the doors in order that it may always be the minimum suitable to the location and use of the door. It is among the objects of this invention to provide a door which is readily adjustable in elevation to meet the requirements of uneven floors and varying thicknesses of floor covering. Other objects and advantages will appear as the description proceeds.

To the accomplishment of the foregoing and related ends, the invention, then, consists of the features hereinafter fully described and particularly pointed out in the claims, the following description and the annexed drawing setting forth in detail but a few of the various ways in which the principle of the invention may be applied.

In said annexed drawing:--

Fig. I is a front elevation-a1 view of a portion of a wall made in accordance with this invention and illustrates a door section and portions of two panel sections; Fig. II is a partial section on larger scale taken along the line II-II of Fig. I with the door leaf removed; Fig. III is a sectional view along the line III-III of Fig. I; Fig. IV Is an isometric view of a portion of a clamp plate; Fig. V is an isometric view of the upper comer portion of a strike frame; Fig. VI is an isometric view of a lower corner of a strike frame; and Fig. VII is a horizontal section of a form of strike frame which requires no clamp plate.

In the form illustrated, a wall is constructed of a series of panel sections and door sections assembled in horizontal relationship to each other, the end verticals of each section constituting half posts which may be secured together in any suitable manner. The invention is equally applicable to walls in which separate posts or supports are interposed between adjacent panel or door sections. The support members or verticals of each section are shimmed or otherwise elevated to a common level as indicated by line LL of Fig. I, by means of shims S or other suitable means. A strike frame is provided made up of the horizontal member 20 and the vertical members 30 which may be installed in three pieces or welded into a solid frame. Suitable hinges or butts H are provided, and a door leaf D is mounted in the strike frame.

The strike frame and door are securely mounted against the support members, but in such a manner as to permit vertical adjustment. For this purpose we prefer to form the support member V with a longitudinal groove 31. A clamp plate 40 is provided to nest within the vertical member 30 of the strike frame. This clamp plate is further provided with a rib 41 to fit loosely within groove 31 of the vertical and obstruct the passage of light between the strike and the vertical.

Suitable embossings 42 are provided at intervals in the clamp plate to accurately position it on the vertical with respect to the groove. These embossings may be tapped to receive a screwth readed member 32 which serves to clamp the strike frame securely against the vertical. Such screw-threaded members pass through slotted holes 24 in the vertical thereby permitting relative movement. The clamp plate may be welded to the strike frame or may be slidable axially therewithin.

Another form of construction is illustrated in Fig. VII. The strike member is provided with integral outstanding flanges which enter a groove 31 of a vertical member V. The bolts are placed with their heads within the strike member by sliding into position from one end, means being provided to prevent rotation when in place. The vertical is then brought into assembled relation and nuts are provided to complete the'assemblage.

A panel member 21 is also carried by the support members. In the preferred form cleats or semi-punchings 23 are provided on the support members and the panel member is located thereby and held in place by means of a through-bolt 25 passing between the supports at either end of such panel member. The panel member may, of course, be welded or otherwise secured to the support members. A floating or telescopic member 22 is provided to overlap the panel member and the strike frame and provide a finished appearance as the strike frame is moved relatively to the panel member. This floating member may take the form of upstanding legs on the strike frame entering an opening in the panel member or vice versa, but we prefer to provide a separate part slideable within both the strike frame and the panel member in order to permit the maximum relative motion. In the preferred form this floating member may be a. channel with the flanges rebent outwardly as at 26 to prevent withdrawal from the member which it engages. The web of such channel may be provided with spacer platesji'l welded or otherwise fixed thereon. Such spacer plates or outwardly directed flanges may serve the further purpose of centralizing the floating member and preventing scratching of the finish.

Itwill thus be seen that this construction as a whole is adaptable to widely-varying condi- 1 tions, as the door clearance is adjustable to meet hinges has greater clearance than the other.

In the construction illustrated the support members constituting the end verticals of adjacent panel sections and door sections are secured in spaced relationship by means of clip C and facing members P are removably secured to such clips to provide a finished appearance and ready access to the clamping screws 32 which are wholiy concealed in the completed structure.

Other modes of applying the principle of the invention may be employed, change being made as regard the details disclosed, provided the means stated by any of the following claims, or the equivalent of such be employed.

We therefore particularly point out and distinctly claim as our invention.

1. In metallic partition construction, a door section comprising support members elevated above the level of the floor; a strike frame carried by such support members and vertically adjustable with respect thereto; and means for securing such strike frame to such support members, such means including clamping means and positioning means.

2. In partition construction, a door section comprising support members elevated with respect to the floor; a strike frame carried by such members and vertically adjustable with respect thereto; a panel member above such strike frame and also carried by such support members; and an overlapping member connecting such panel member and such strike frame and permitting relative motion therebetween.

3. In metallic partition construction, a door such support members and adjustably clamped thereto by means of screw threaded members; and

. a door leaf carried-by such strike members.

4. In metallic partition construction, a door section comprising support members of generally channel form, having a groove and slotted holes; a. strike frame carried by such support members; positioning means entering such strike frame and such groove; and clamping means between such strike frame and such support and passing thru such slotted holes.

5. In metallic partition construction, a door section comprising support members elevated with respect to the floor; a strike frame carried by such support members and vertically adjustable with respect thereto, the top member of such strike frame presenting a receiving portion; a panel member above such strike frame carried by such support members and presenting a receiving portion; and a floating member entering the receiving portions on such strike frame and such panel member.

6. In metallic partition construction, a door section comprising support members elevated with respect to the floor; a strike frame carried by such support members and vertically adjustable with respect thereto; means for positioning such strike frame laterally with respect to such support members; adjustable means for clamping such strike frame to such support members; a telescopic member above such strike frame; a panel member above such strike frame and carried by such support member, and overlapping such telescopic member; and a door leaf carried by such strike frame.
