R. S. MEDOW ADJUSTABLE ARCH STRUCTURES Filed Aug. 28, 1967 33 34 33 f 32 IO 5 l6 4|- I i i INVENTOI? RCggERT S. MEDOW United States Patent Claims ABSTRACT OF THE DISCLOSURE An adjustable arch structure consisting of a base member, a frieze member and a substantially semi-circular and hollow column each of which are prefabricated as separate parts capable of being erected in any sized wall or room by virtue of the column being telescopically mounted in the base and frieze member and secured thereto by a bracket which consists of an elongated body portion with offset portions and shoulders mounted thereon engaging the rear portion of the column at both the outside and inside surfaces and threaded bolts extending through openings in the front wall of the base and frieze members and received by threaded openings in said bracket.

This invention relates to ornamental building structures and is more particularly directed to adjustable arch structures.

At the present time ornamental arch structures for indoor and outdoor installation are not available as a prefabricated over the counter purchase. In order that a person may satisfy his desire for such a structure, he must first obtain the services of an architect to design the particular ornamental arch structure, that will fit in that part of a room or outside wall where he wishes to have it installed. Then he obtains the services of one who is capable of fabricating custom made arches whether of wood, cement or plastic material. Lastly, he hires workmen who are skilled in the erection of the ornamental arch structure so that finally the ornamental arch structure is erected as desired. However, it is obvious that not only is the cost of such an article of structure exceedingly high, since highly skilled labor is used throughout the project, but also the time consummed from start to completion is great.

The present invention contemplates avoiding the high cost of custom made arch structures and the need for skilled help to make and install the arches by prefabricating the arch structures which are flexible in their arrangement, adjustable to fit different sizes of rooms and walls, and which can be erected by unskilled help with nothing more than a simple tool.

Therefore, a principal object of the present invention is to provide adjustable arch structures made of parts which are prefabricated of fiberglass in mass production quantities whereby the cost of manufacture is low and the installation thereof so simple that it can be accomplished by an unskilled person with use of a screwdriver alone.

Another important object of the present invention is to provide prefabricated arch structures that can be purchased over the counter and which are sufiiciently flexible in sizes so that one need not cut or alter the various parts in order to be installed properly.

A still further object of the present invention is to pro vide prefabricated arch structures constructed of parts of the well known types of arch structures and which may have any desired designs thereon as well as the parts beinginterchangeable so that a person may select any of the designs or combination thereof.

With these and other objects in view, the invention will be best understood from a consideration of the following detailed description taken in connection with the accompanying drawings forming a part of this specification, with the understanding, however, that the invention is not con- 3,421,269 Patented Jan. 14, 1969 fined to any strict conformity with the showing of the drawings but may be changed or modified so long as such changes or modifications mark no material departure from the salient features of the invention as expressed in the appended claims.

In the drawings:

FIGURE 1 is a front elevational view of a Romanesque arch structure constructed in accordance with my invention.

FIGURE 2 is a cross sectional view taken along the line 2-2 of FIGURE 1.

FIGURE 3 is a cross sectional view taken along either of the lines 33 of FIGURE 2.

FIGURE 4 is a rear elevational view of a portion of my arch shown in FIGURE 1.

FIGURE 5 is a perspective view of the column retaining bracket.

FIGURE 6 is a front elevational view of a Corinthian arch structure embodying my invention.

FIGURE 7 is a rear elevational view of the Corinthian frieze assembly.

Referring to the drawings wherein like numerals are used to designate similar parts throughout the several views there is shown in FIGURE 1 a Romanesque arch system in which all of the different parts are included to make any arrangement desired and to fit any sized wallv In general, these different parts which constitute the Romanesque arch consist of a base 11, column 10, the following friezes namely, a left and right single arch friezes 12 and 13, a double arch frieze 14 and a straight frieze 15, a frieze connector 16 and a column retaining bracket 17. Except for the column retaining bracket 17 which is made of sheet metal, the remaining parts of my Romanesque arch is made preferably of fiberglass by the usual cavity mold process utilizing highpressures and temperatures.

The columns 10 which extend between bases 11 and the various friezes 12, 13 and 14 are held in position by brackets 17 as is explained in detail hereinafter. The cross sectional shape of the columns 10 is approximately equal to or slightly less than semi-circular in configuration and may be fluted on the outer surface as shown by FIGURE 3 by the grooves or depressions 20 extending therealong.

The base 11 consists of a channel shaped member having a rectangular front wall 21 slightly depressed to form a border thereabout, and side walls 22 with necking portion 22 extending upwardly of the front and side walls 21 and 22 to engage the semicircular outer surface of the column 10. On the inner surface of the front wall 21 is a landing or projection 23 which engages the lower end portion of the column 10 which projection 23 in combination with the bracket 17 retains the columns 10 securely in position. The outer edge 19 of the sidewalls 22 is thinner than that of the remainder of the walls 22 thereby forming a shoulder 24 upon which the ends of bracket 17 impinges.

The bracket 17 consists of an elongated flat body member 25 which is precisely equal in length to the width of the columns 10 and at whose ends extend off-set portions 26 set at right angles thereto. At the ends of the off-set portions 26 extend arm portions 27 which lie in a plane parallel to that of the main body portion 25 of the bracket. Each off-set portion 26 is equal in length to the distance the shoulder 24 is from the outer edges 19 of the side walls 22. This compels the outer surface of the main body portion 25 of the bracket 17 to lie in coplanar relation with the outer edges 19 of the side walls 22. With this construction, when the bracket 17 is placed in position against the rear edges of the column 10, the off-set portions 26 will engage the outer surface of the column 10 and the arm portions 27 will rest on the shoulders 24 as the arms 27 fit snugly between the side walls 22 of the base 11. The bracket 17 is then locked in position by bolts 30 that extend through openings 31 in the front wall 21 of the base.

11 and are threaded into threaded bores 32 formed in the arms 27. The landing '23 and off-set portions 2 6 prevent any movement or spreading of the column 10'. To prevent the rear portions of the column 10 from collapsing or moving in the direction toward each other shoulders 33 engage the inner surfaces of the column 10 at the rear edges. The shoulders 33 are formed by a stamping process which forms a groove 34 whose raised portion extends along the inner surface of the bracket 17 along the length of the main portion 25 terminating in shoulders 33 a distance equal to the thickness of the material forming the column 10 from the off-set portions 26.

In the mounting of the bracket 17 on the column 10, recesses are formed in the outer edges of the column 10 for receiving the main body portion 25 so that the latter will lie in the same plane as the outer edges of the column 10 and the edges 19 of the side walls 22 and the column 10 and base 11 will lie evenly against the wall upon which they are being erected. At the upper ends of the columns 10 are the friezes 12, 13 and 14. The friezes l2 and 13 are left and right single arch friezes while frieze 14 is a double arch frieze. All of the friezes 12, 13 and 14 are identical in construction except for their outer configurations having an identically shaped necking 35 which encircle the upper ends of the columns 10 in the same manner as the necking 22 of the bases 11. The column 10 is secured at its upper end to the frieze by the bracket 117 which is identical in structure and function as the bracket 17. The friezes 12, 13 and 14 are provided with a projection or landing 123 which in combination with bolts 130 secure the column 10 to the friezes. Just as with the bracket 17 the column 10 is locked into position by the bolts 130 which draw the column 10 firmly against the landing or projection 123 while the outer edges of the column are wedged between the ofl-set portions 26 and shoulders 33 of the bracket 117.

The left and right single friezes 12 are provided with a straight side wall 36 on the left and right sides respectively, a flat top wall 37 and an arcuate wall 38 on the right and left respectively. With a flat front wall 39 depressed slightly to form a border thereabout and joining the aforementioned walls, a channel member is formed to receive a connector 16 as shown by FIGURE 4. Connector 16 which is channel shaped likewise consisting of a body or face portion 41 with flanges 42 extending at right angle thereto is telescopically received by two adjacent friezes. If the friezes 15, 13 are spaced from each other the connector 16 becomes a spacer connector as shown at the right as viewed in FIGURE 1. The straight frieze is identical in construction as the connector 16 except that it is wider than the latter by a distance equal to the thickness of the walls of the friezes.

The double arch frieze 14 which is channel shaped likewise consists of arcuate side walls 43 extending upwardly of the necking 35 and a top wall 44 joined by a front wall 45 also slightly depressed to form a border thereabout. On all of the depressed front walls such as the walls 21 of the base 11, walls 39, 41 and 48 of the various friezes may be provided with any suitable ornamental design as desired.

It is readily noted from the above description taken in connection with FIGURES 1-5 inclusive, my Romanesque arch structure may be prefabricated to fit any height of room or wall by virtue of the columns 10 that are telescopically adjustable within the bases 11 and friezes 12, 13 and 14. Likewise, my Romanesque arch structure will fit in any length of wall or any desired combination of friezes may be effected.

Also, other types of arch structures may be adapted for prefabrication and installation in the manner described hereinabove. As an example, FIGURE 6 shows a part of a Corinthian arch structure consisting of structure which is identical to that described above except for the structure of the frieze. The Corinthian arch structur consists of thebase 111 in which the column is tele scopically secured by the bracket 117 in the same manner as explained in connection with the Romanesque arch structure hereinabove. The frieze of the Corinthian arch system consists of a straight frieze which is identical in construction with the straight frieze 15 described hereinabove to which a frieze base 50 is attached. The frieze base 50 that has the configuration that is distinctive of the Corinthian arch is fastened by screws 51 which extend between the walls of the straight frieze 115 and the column head 50 as shown by FIGURE 7. End straight friezes 112 are of identical construction as the straight frieze 115 except that they are proportionally shorter in length.
