Q 70 2ZZ 66 f j/jz INVENTOR PHILLIP CRAIG WELCH ATTORNEYS BOOTH CONSTRUCTION This invention relates to a booth construction, especially adapted for telephone booths. In one of its aspects, the invention relates to a booth construction in which side panels, a back panel, and shelf panels are quickly and easily secured together through recessed fastening means, and pockets formed in the edges of the shelf panels open into the bottom thereof to permit passage of shoulder screws in the side panels into the pockets while the side panels are securely fastened to the back panel.

In commonly assigned, copending U.S. Pat. application Ser. No. 669,155 filed Sept. 20, 1967, now Pat. No. 3,451,362, there is disclosed and claimed a booth construction wherein a back panel is fixed between two sidewall panels and at least one shelf is fixed to the sidewalls. The booth is of a knockdown construction and all panels are fastened together through flexible, recessed fastening means. In constructing this booth, the side panels are first fixed to the shelf panels. The side panels are then spread apart so as to permit insertion of the back panel between the sidewalls.

I have now discovered still another means of assembling like booths in which the shelf panels are securely locked in place but can be disassembled if desirable, and wherein the side panels are first secured to the back panel and then the shelf panels are secured to the side panels.

By various aspects of this invention one or more of the following, or other, objects can be obtained.

It is an object of this invention to provide an improved booth construction for telephones and the like, which booth can be shipped in knockdown form and easily and quickly assembled without the use of tools.

It is a further object of this invention to provide an improved booth construction having strong assembly means which are substantially hidden from view to minimize the danger of accidental disassembly.

It is yet another object of this invention to provide an improved knockdown booth construction which can be assem bled quickly and easily while being of ingenious construction to hide assembly fasteners between panels, but which booth can be disassembled easily by persons having specific knowledge of the assembly techniques.

It is still another object of this invention to provide an ingenious knockdown booth construction for telephones and the like wherein panels are quickly and easily assembled at point of use and locked to each other for durable use and to prevent vandalizing.

It is another object of this invention to provide a knockdown booth construction which lends itself to efficient mass production methods with semiskilled labor, can be shipped in knockdown form to minimize shipping costs, and which can be easily and quickly assembled at point of use.

It is yet another object of this invention to provide a booth construction which lends itself to interlocking tandem booth construction during initial construction or subsequent to construction of a single booth.

Other aspects, objects, and the several advantages of this invention are apparent to one skilled in the art from a study of this disclosure, the drawings, and the appended claims.

According to the invention, there is provided a quickly and easily assembled booth construction for telephones and the like wherein said booth has a back panel, side panels joined to the side edges of the back panel, and shelf panelsjoined to the side panels. The side panels are joined to the back panel and to the shelf panels through recessed fastening means..Pockets are formed in the side edges of the shelf panels and clips are fixed in the pockets. Each of the clips has an open-ended slot for receiving the head ofa shoulder screw which is fixed in a side panel and which projects into the pocket and engages the slot of the clips to tightly secure the shelf panels to the side panels. One shoulder screw is fixed in the side panels for each pocket and clip. At least some of the pockets in the shelf have a bottom wall cutaway so as to form an opening on the bottom thereof to permit passage of the shoulder screws into the pockets after the side panels have been securely fastened to the back panel. In this manner, the booth can be constructed by first fixing each side panel to the back panel and then fixing the shelves between the sidewalls.

In a preferred embodiment, at least one of the clips in each of the shelf panels has a locking flange to retain a shoulder screw at the terminal end of the slot when the shoulder screw is engaged by the clip.

The invention will now be described with reference to the accompanying drawings in which:

FIG. 1 is a perspective view ofa booth according to the invention;

FIG. 2 is an exploded view of the parts forming the booth illustrated in FIG. 1;

FIG. 3 is a front elevational view of the booth showing an initial stage in the assembly of the booth;

FIG. 4 is a partial sectional view taken along lines IV-IV of FIG. 3;

FIG. 5 is an enlarged view of the encircled area A in FIG. 3; FIG. 6 is a sectional view taken along lines VIVI of FIG.

FIG. 7 is a front elevational view of the booth shown in the completed assembly;

FIG. 8 is a fragmentary sectional view taken along lines VIIIVIII of FIG. 7; and

FIG. 9 is a sectional view seen along IXIX of FIG. 8.

Referring now to the drawings, there is shown atelephone 12 which is supported within a booth comprising aback panel 14,sidewall panels 16 and 18, andshelf panels 20 and 22. The booth can be supported on a wall by achannel bracket 24 havingslots 26 and 28 for affixing the channel bracket to the wall through suitable fastening means such as screws (not shown). As seen in FIG. 4, the channel bracket has a downwardly turnedfront edge 30 and an upwardly turnedfront edge 32 for retaining an attachingbracket 34 having tappedholes 36 forscrews 38. Thechannel bracket 24 fits within a routedchannel 40 in the back of thebackwall panel 14. The attachingbracket 34 in turn tits and slides within thechannel bracket 24. As thescrews 38 are tightened, theback panel 14 is drawn tightly against the wall.

On each side edge of thebackwall panel 14, anupper pocket 42 and alower pocket 44 is routed out. Eachlower pocket 44 has an opening orwindow 45 in the front ofpanel 14. Theopening 45 is so positioned in thebackwall panel 14 that it is hidden from view byshelf 20 when that shelf has been assembled into position betweensidewall panels 16 and 18, and againstbackwall panel 14. Each pocket contains a slottedclip 54 forengaging shoulder screws 46 in thesidewall panels 16 and 18 (FIG. 5 and 6). One shoulder screw is fixed in a side panel for each pocket and clip combination. Each clip has anend portion 56 secured to theback panel 14 through ascrew 57, and anend portion 58 secured to theback panel 14 through ascrew 59, the end portions beingjoined by a raisedcentral portion 60 having an open-ended slot 62. The slot forms wedging surfaces 64 on the inner portions thereof. The wedging surfaces 64 slope inwardly from the open end to the closed end of the slot.

The shoulder screws 46, which are threadably secured to the sidewall panels have ashoulder 48 and ahead 50 separated by ashank 52. The shoulder screws are well known in the art and are described more completely in a commonly assigned copending U.S. Pat. application, Ser. No. 733,047, filed May 29, 1968 now Pat. No. 3,491,820.

The joint fastening system preferably used with this invention and shown in FIGS. 5, 6, 8 and 9 is more fully described and is claimed in said copending U.S. Pat. application, Ser. No. 733,047. Another suitable joint system for this invention has been disclosed and claimed in still another commonly assigned copending U.S. application, Ser. No. 669,155, filed Sept. 20, I967 now Pat. No. 3,451,362. Both of these applications are incorporated herein by reference.

The joint construction between theshelves 20 and 22 and the sidewalls I6 and 18 are of similar constructionsReference is now made to FIGS. 8 and 9 for a disclosure of one-joint construction between the sidewalls and the shelves. Apocket 68 is routed out in the side edge of each shelf panel to correspond withshoulder screws 46 in the side panels. One shoulder screw is provided in a side panel for eachpocket 68 in the side edges of the shelf panels. In the embodiment illustrated in the drawings, twoshoulder screws 46 have been placed in each sidewall panel for each shelf, making a total of four shoulder screws supporting each shelf. Thus, there are four pockets formed in each shelf.

Thepocket 68 has a slottedclip 54 fixed therein. The clip is identical with the clip illustrated in FIGS. 5 and 6 except that a lockingflange 66 is formed in the slottedclip 54. The lockingflange 66 extends outwardly towards the edge of the shelf fromend portion 56 beneath the open-endedslot 62 and terminates just short of the terminal position of thehead 50 ofshoulder screw 46. The locking flange permits the shoulder screw to be inserted in the slot, with the lockingflange 66 being deflected inwardly as the shoulder screw slides into the end of the slots. Once in position, the shoulder screw cannot be removed from the slot due to the fact thathead 50 will strike the terminal end of the lockingflange 66. By depressing inwardly the lockingflange 66 theshoulder screw 50 can be removed from the slot.

Anopening slot 70 is formed in the bottom of the shelf to aid in assembling the shelves to theside panels 16 and 18 and to assist in removing the locking clips. Preferably, only one joint containing a locking clip as illustrated in FIG. 9 is positioned in each shelf. The other fastening means for the joints are preferably those illustrated in FIGS. 5 and 6. In thosepockets 68 containing the clips without the locking flange, theslot 70 need only be long enough to permit insertion of the head of the shoulder screw. Thus, theother slot 70 will be somewhat smaller than that illustrated in FIGS. 8 and 9.

The booth is assembled by first fixing theback panel 14 to a wall or other suitable supporting member preferably through thewall mounting bracket 24. The telephone is then preferably mounted directly to the wall onpanel 14. Theside panels 18 and 16 are then positioned so that the shoulder screws 46 are in the top portions of thepockets 42 and 44. Theside panels 18 and 16 are then pulled downwardly to securely fasten the shoulder screws in the slotted clips 54. Theshelf panels 20 and 22 are then dropped in place so that the shoulder screws pass through theslots 70 and intopockets 68. The shoulder screws 46 will be positioned in the rearmost portion of theslots 70. Theshelf panels 20 and 22 are then sequentially pushed back against theback panel 14 so as to lock the shelves in place.

In a preferred embodiment of the invention, the clips in both pockets contain locking flanges such asflange 66 illustrated in FIGS. 8 and 9. These flanges then securely lockside panels 16 and 18 in place onbackwall panel 14. If desirable, these side panels can be removed by inserting a screwdriver blade or similar tool through opening 45 to depress the locking flange and then forcing the side panel upwardly with respect to thebackwall panel 14. If the booth needs to be disassembled, a screwdriver or similar tool can be inserted throughslot 70, between the raisedportion 60 and the lockingflange 66, and then turned so as to deflect the lockingflange 66. The shelf panel can then be pulled outwardly to disengage the shoulder screws from the clips.

Alternately, only the innermost pockets in the ends of the shelfpanels 20 and 22 need to be provided with openingslots 70. Since theclips 54 are of a flexible nature, the side panels I6 and t8 can be spread slightly to permit insertion of the outermost shoulder screws 46 into the pockets for engagement with theclips 54.

The booth construction according to the invention provides a construction in which the means ofassembling the booth are not readily visible to the untrained eye. The booth cannot be disassembled without knowledge of the operation of the locking clips illustrated in FIGS. 8 and 9. This is significant due to the widespread pilferage and vandalism to which telephone booths and the like are subject.

The booth can be assembled in place quickly and easily by a single person without the use of tools. By the construction design, each panel is assembled seratim to the wall in a simple one-step operation, thereby eliminating the necessity of lifting a heavy, preassembled structure. The construction is strong and does not lent itself to disassembly without specific knowledge of the nature of the locking clips. For example, the sidewalls cannot be pulled up after the assembly because of the locking flanges inpockets 44. In any event, theshelves 20 and 22 must be removed prior to removal of thesidewall panels 16 and 18. It should be pointed out also that theshelf 20 cannot be removed without first removing theshelf 22. This is so because the locking clip in the end of theshelf 20 cannot be unlocked without first removing the bottom shelf. The distance between the shelves does not permit a screwdriver to be inserted into theopen slot 70 without first removing thebottom shelf 22.

The booth construction of the invention is a knockdown construction which lends itself to less expensive mass production techniques where parts are produced faster with semiskilled labor as opposed to the conventional skilled labor and extensive hand operations. In other words, each kind of panel is produced in identically the same manner, and these panels are interchangeable. Thus, there is no problem of fitting between the panels. The mass production techniques are less expensive than the conventional woodworking techniques.

Further, the knockdown construction is less expensive for shipping. The disassembled panels can be laid flat adjacent each other without bulky air space.

By the ingenious construction, strong joints are provided between the panels and the fastening means are hidden to prevent vandalizing disassembly. Further, the panels can only be constructed by one who is knowledgeable with the construction method.

The locking assembly of the panels minimizes vandalizing disassembly and also provides a more durable construction for use of the booth.

Plural booths can be arranged in tandem in an interlocking relationship using a common side panel. This tandem arrangement can be accomplished during the initial installation procedure or subsequent thereto should a tandem arrangement prove desireable after the installation of a single booth. The common side panel will have shoulder screws projecting from either side thereof in identical relationship with respect to the sidewall. After the backwall panels for the adjacent booths have been secured to the wall (or to another suitable support) the common side panel is placed between the edges which are then forced against the common side panel with the shoulder screws inpockets 42 and 44. The common side panel is then pulled downwardly to secure the common sidewall panel to thejuxtaposed backwall panels. The remainder of the booths can then be constructed in identical manner as described above.

In adding another booth in tandem with an assembled booth, it is necessary to disassemble the constructed booth by removing the shelves and one sidewall panel. The side panel of the constructed booth is then replaced by a common side panel having screws on both faces and construction of the tandem booths is completed as described above.

Whereas the invention has been described with respect to a booth mounted on a wall, it is within the scope of the invention to provide a booth assembly such as described mounted on a supporting base in freestanding relationship on the floor.

Reasonable variation and modification are possible within the scope ofthe foregoing disclosure and drawings without departing from the spirit ofthe invention.
