Filed Oct. 12. 1961 2 SheetsSheet 2 United States Patent 3,205,594 DISPLAY DEVICE Leon M. Gilbert, 1600 Fell St, San Francisco, Calif. Filed Oct. 12, 1961, Ser. No. 144,653 6 Claims. (Cl. 3553) This invention relates to a device that permits perspective observation of a simulated room corner portion, and more particularly to a portable display device for demonstrating the placement and arrangement of physical components in a determinate space and for demonstrating background arrangements that afford aesthetic visual impressions. The device has particular utility in simulating in depth the corner portion of a room to permit decor ensembles to be planned therefor by visual observation, but it may be used in other environments; for example, as a childs toy or amusement device.

Considering the device in connection with its utility as a decorator aid, it should first be appreciated that the untrained person has diificulty visualizing a decor ensemble for a room-that is, color and color combinations, material textures and combinations thereof, furniture placement, etc. Consequently, it is usual for decorators and sales persons to provide cloth and color samples that may be grouped together to permit some idea to be obtained of a decor ensemble that is being suggested. Sampling systems of such type though used extensively are in no sense satisfactory for they do not permit the viewer a perspective observation of an ensemble as it actually will exist, and he must still translate his impressions by mental visualization into a complete decor ensemble.

Accordingly, an object of the present invention is to provide a device that permits perspective observation of a simulated room corner portion so that realistic room arrangements can be viewed. Another object of the present invention is the provision of a display device which simulates in depth the corner portion of a room and will permit decor ensembles for such room to be planned by visual observation. Still another object is that of providing a device which permits decor ensembles to be readily changed from one to another, both as to background color and texture and as to the placement and arrangement of furniture and other articles in the room. A further object is to provide a device of the character described that is portable and easily carried from one location to another; and that enables various decor ensembles to be carried conveniently in kit form so that a considerable variety of suggested decor ensembles are available for quick combination and interchange whereever the device is used. Additional objects and advantages of the invention will become apparent as the specification develops.

Illustrative embodiments of the invention are shown in the accompanying drawings, in which:

The structural embodiment of the invention illustrated in FIGURES 1 through 7 comprises in general a support structure A, a frame B, a container C, a group of panels designated in their entirety with the letter D, and a plurality of articles E. The support structure A has a viewing side 15 and a rear side 16, and comprises a framework 17, preferably formed from a transparent material such as Plexiglas, and is made up of individual elements oriented to simulate the lines of mergence of the ceiling, floor, and adjacent two walls of the corner portion of a room. For identification, these elements are denoted with the numerals 18 through 22, inclusive; and it will be apparent that the element 18 represents the vertical line of mergence of two room walls at a corner defined thereby, the

elements

19 and 20 represent the respective lines of mergence of such two room walls with the ceiling, and the

elements

21 and 22 respectively represent the lines of mergence of the same two room walls with the floor.

The

elements

19 and 20 are connected to the element 18, as are the two

elements

21 and 22; and each of the eiling-representing and floor-representing elements are connected to the framework 17 which has a generally rectangular configuration and includes a pair of vertically spaced and substantially

parallel members

23 and 24 and a pair of horizontally spaced, substantially

parallel members

25 and 26. Thus, the support structure A defines a plurality of individual segments respectively simulating elements of a room corner portion; and more particularly, the

elements

18, 19, 21 and 25 define one wall, the

elements

18, 20, 22 and 26 define another room wall, the

elements

19, 20, 22 and 26 define another room wall, the

elements

19, 20, and 23 define the room ceiling, and the

elements

21, 22, and 24 form the floor of the room. For convenience, the wall segments (each of which has a trapezoidal configuration) are respectively designated with the

numerals

27 and 28, and the ceiling and floor segments (each of which has a triangular configuration) are respectively designated with the

numerals

29 and 30.

The frame B in the structure shown has a generally rectangular configuration defined by

side members

31 and 32 and by top and bottom members 33 and 34. These members are respectively secured to those adjacent thereto, and may be integral therewith. The frame B also provides a face 35 extending thereacross having an enlarged, generally rectangular opening 36 which is used to view the support structure A there-through, and more especially a decor ensemble carried thereby. The face 35 is secured to the various elements 31 through 34, and may be formed integrally therewith. Mounted within the frame B behind the perimetric edge portions of the face 35 so as to be generally concealed thereby are one or more lights 37 which are preferably daylight fluorescent bulbs. Suitable conductors (not shown) electrically connect each of the lights 37 with a plug-equipped lead line 38 that may be connected to a suitable convenience outlet for energizing the lights 37. If desired, the frame member 34 may have a recess 39 formed therein to permit the lead line 38 to enter the interior of the frame without disturbing the support structure A.

The support structure A i I mounted within the frame B, and also to be hingeclly re s adapted to be removably I Thus, the ceiling panel 52 is lated thereto for swinging movement between a viewing position and an outward position. Both ofv these func'- tions are accomplished in the present device by equipping the support structure element 24 with a pair of spaced apart hinges 40 and4-1 of tubular construction which are respectively adapted to slidably and rotatably receive therein a pair of

pins

42 and 43 carried by the frame member 34. It will beapparent that the

pins

42 and 43 may be respectively inserted into the tubular hinges and 41 by aligning the same therewith, and then displacing the support structure A along the length of the pins to telescope the same into the hinges. Thereafter, the support structure A may be swung between a viewing position shown by full lines in FIGURE 3, and anoutward position which is shown by broken lines in the same figure. It should also be noted that the support structure A is reversibly mountable within the frame 'Bone of the positions (as shown in FIGURE 3) being forviewing, and the other ,(which is shown in FIGURE being for storage and transport. Latch means may be employed to secure the support structure A in its viewing position within the frame B, and such latch means may be of any suitable form as, for example, the

spring clip elements

44 and 45 respectively provided by the frame B and support structure A.

The frame .B is removably mountable within the top section 46 of the container C, which is portable and may be in the form of a suitcase. The container is provided with a bottom section 47 hingedly secured to the top section 46, and the two container sections define a compart ment 48 in which the frame B and support structure A are received for storage and transport. The container is equipped with a handle 49 of conventional type, and the sections thereof may be secured in their closed position by conventional latch structure (not shown). The hinges pivotally relating the

sections

46 and 47 may be of usual design.

The frame B, as shown mostclearly in FIGURE 5, is snugly received within the contained section 46 and may be withdrawn therefrom and replaced therein with a sliding movement when the container is open. Preferably, the support structure A is inverted from the viewing position thereof illustrated in FIGURE 3 into the storage position of FIGURE 5 when stored within the container, so as to free most of the compartment 48 for storage of panels D and articles E; If desired, friction springs or latch structure, etc.may be employed to retain the frame B and support structure A withinythe upper portion of the compartment 48, when the container is closed.

Four panels D are illustrated in FIGURE 6, and for convenience they are respectively designated with the numerals 50 through 53, inclusive. The

panels

50 and 51 have a trapezoidal configuration, and form the side walls of a simulated room; while the

panels

52 and 53 have a triangular configuration and respectively form the ceilslidable into the channels 54 provided by the elements 19 and that form the'lines of mergence of the ceiling and side walls of the simulated room. The panel 53 is slidable into the channels provided by the floor-defining

elements

21 and 22, and the

panels

50 and 51 are receivable Within'the channels provided by the paired elements 19-21 and 20-22.

FIGURE 2 shows a plurality of panels D appropriately mounted on the support structure A, and it will be apparentt-hat each of the panels is decorated or covered so that they provide as a group a simulated decor ensemble for I a room. More particularly, the floor panel 53 is covered with a swatch of carpeting or simulated carpeting of suitable color, design and/ or texture, the panel 51 is designed to illustrate a wall'covered with draperies, and the side wall panel 51) and ceiling panel 52 are colored or otherwise configurated to define with the other panels a complete decor ensemble for a room.

A great many panels D may be carried within the container C, as shown in FIGURE 5, so that many suggested decor ensembles are available for convenient showing. Addition-ally, each selected decor may be completed by positioning one or more utilitarian or decorative articles within the simulated room, such as the furniture replicas E shown in FIGURE 7. These articles are equipped with ing and floor of such room. The panels are appropriate- I ually or as a group with other panels to permit any decor 1 ensemble to be readily changed. In the particular device considered, such cooperative mounting structure includes channels 54 provided by the various elements 19 through 22 of the support structure, and edge portions of the panels which are slida-bly receivable within such channels.

means for. removably locating the same within the room, and'each may be provided wit ha pin or nail 57 to pierce the floor panel 53 for the purpose of removably but positively locating the article thereon. It will be apparent that'a number of articles may be stored within the compartment 48 along with the panels D. It should be noted that the four panels D are notalways necessary. toshow acomplete decor ensemble for a room, and, for example, the floor panel 53 might be omittedand the frame B simply placed upon a suitable floor covering which would then take the place of the panel.53 when the simulated room is observed from the viewing side 15 of the support structure A. In such event, and if desired, the support structure A (or the support structure and frame B) may be tilted to orient the segment 30 in coplanar relationship with such floor covering; or if one of the wall panels is omitted, the device may be tilted to establish .a coplanar relationship of the segment 27 (or segment 28) with the surface that is being substituted for such omitted wall panel.

The modified structure illustrated in FIGURES 8 and 9 is generally similar to the embodiment heretofore described except that the construction of the support structure and frame has been varied slightly. Since the two embodiments are similar, the primed form of the same reference numerals is used wherever practicable to identify corresponding parts and the container in its entirety is denoted C. It has top and bottom sections 46 and 47' hingedly related along one of their corresponding longitudinal edge portions, and the container defines therein a compartment 48'. The top section 46' has a large rectangular opening 36" in the face 35 thereof, and the opening 36 is adapted to be selectively opened and closed by a removable cover 58 that is slidably received within a pair of guides or channels 59 and .60 secured to the top section 46" by any suitable means. It is evident that the cover 58 may be displaced longitudinally along the length of the

guides

59 and 60 to selectively cover and uncover the opening 36.

The top section 46 of the container serves the function of the frame B described in connection with the embodiment illustrated in FIGURES 1 through 5, and, therefore, is equipped with one or more lights. 37' that illuminate the interior of the support structure A which is hingedly secured to the frame-serving top section 46' of the container. The support structure A rather than being of unitary construction is segmented and, specifically, comprises four

segments

27, 28, 29 and 30 each of which is pivotally secured to the top section 46 by conventional hinge means. Consequently, each of the segments is pivotal with respect to the top section 46' of the container and also with respect to each other.

More pointedly, the

segments

27 and 28 have a trapezoidal configuration; respectively correspond to the side walls of a simulated room; and are hingedly secured to the top section 46' along opposite transverse edge portions thereof. The segments 29' and 30 are of triangular configuration; respectively correspond to the ceiling and floor of the simulated room; and are hingedly connected to the top section 46' along opposite longitudinal edges thereof.

As a result of this construction, the segments are selec tively movable between an extended viewing position which is shown in FIGURE 8 and a collapsed storage position as shown in FIGURE 9. In their storage position, the segments swing into the container section 46 which is desirable since it permits a substantial number of panels D and articles E to be stored within the bottom section 47' of the container. The segments 27 through 30' may be secured to each other when in their viewing position by any conventional latch structure, as for example, the

straps

61, 62 and 63 shown in FIGURE 8; and the various elements of the support structure A are provided with channels, such as the channels 54 shown in FIGURE 4, to detachably secure panels D in position thereon.

A further modification of the device is shown in FIG- URES 10 and 11, and though similar to the structural embodiments heretofore described, differs therefrom in that the support structure A" has a generally planar configuration rather than being of pentahedral form as is the case with the support structure A and structure A in its viewing position. The support structure A is divided into four segments 27", 28", 29 and 30"the first two being of trapezoidal configuration and corresponding to side walls of a simulated room and the latter two being of triangular configuration and respectively corresponding to the ceiling and floor of such room. The perimeters of these segments are defined in part by the elements 18" through 22" and, as shown in FIGURE 11, these elements form channels 54" which serve to slidably receive therein edge portions of the panels D to removably secure the same to the support structure.

The support structure A" may be used in connection with either of the containers C or C and may be pivotally secured thereto by appropriate hinge elements such as the tubular hinges 40" and 41" which are adapted to telescopically receive the hinge pins 42 and 43 shown in FIGURE 1. Thus, the support structure is pivotal between a viewing position in which it is substantially parallel to .the plane of the face 35 of the frame B and a position outwardly therefrom in which the panels D are readily interchanged. Latch means 45" may be used to secure the support structure in the viewing position thereof.

Since the device is quite portable and affords accessible storage space for a substantial number of panels D, it is readily usable as a home demonstrator although it certainly may be used permanently at one location. In any of its forms, the device enables perspective observation of a simulated room, and, therefore, a realistic visual impression can be obtained of any suggested decor ensemble. Additionally, any such ensemble may be altered significantly by changing one or more of the panels D or may be changed in its entirely by replacing all of the panels with another group thereof.

The panels D may be painted, covered, or otherwise decorated to provide various aesthetic impressions and the ready interchange and substitution of panels affords an infinite variety of decor combinations that can be observed in depth to give a realistic visual impression. Variant arrangements may be employed to achieve the substitution of one panel for another. For example, a plurality of Wall panels 50 could be arranged as an elongated strip, preferably flexible and coiled upon a spool, and the strip could be moved across the support structure segment 28 to successively position each panel 50 in juxtaposition therewith. Similar strip arrangements could be used in connection with each of the

panels

51, 52 and 53; and each decor ensemble could be altered or replaced by moving one or more of the strips to change the panels therealong. An arrangement of this type would lend itself to an automatic operation in which the various strips and spools could be connected to a drive assembly that would be manually or sequentially actuated to successively change the decor ensembles being viewed. Also, the panels could be grouped on rotatable discs which would be manually or automatically rotated to successively position the various panels in alignment with the corresponding support structure segments.

The transparency of the support structures; or at least the

various elements

19, 20, etc., thereof; contributes to the aesthetic representation of a room decor ensemble in that the colors, textures, etc. respectively corresponding to the various room walls (ceiling, floor and side walls) appear in contiguous relation as is the case in an actual room.

While in the foregoing specification, specific embodiments of the invention have been described in detail for purposes of making a complete disclosure thereof, it will be apparent to those skilled in the art that various changes may be made in such details without departing from the spirit and principles of the invention.
