  • the apertures 111 in all structural parts of the present invention are made with the same degree of accuracy as to their dimensions and relative spacings so as to eliminate the danger of any errors in the assembled structures. This is an important feature as the errors in the prior art devices frequently are cumulative due to inaccuracies in the location of the holes, thereby resulting in a final assembly that fatally deviates, for example, from the intended vertical position.
  • bracing members 138 (FIG. 8) and provided with apertures 111 can be used in the assembly.
  • FIG. 67 illustrates how, by pivoting the two members a and 110b, connected with the structural member ll0c by the pivotal connecting means in the directions A and B, such angular assembly can be readily folded together into a small part of box-like shape for storage and/or transportation.
  • FIG. 8 illustrates how, by the use of standardized parts in accordance with the present invention, described in connection with FIGS. 1 through 7, one can obtain a structural assembly which can be used, for example, as a housing or tent-like structure to accommodate four to six persons.

  • the use of the plate member 160 permits an extension of the structural assembly in the direction of arrow B by the use of further structural elements, such as, angle members 110 also indicated in phantom lines in this figure.
  • the particular configuration of the plate members 150 and 160 i.e., the removal of the apex 151 in FIG. 11 and of the portion 162 in FlG. 12 provides a free space so that, for example, a sectional member 110 could be extended uninterruptedly through the angular assembly through the opening formed thereby as shown in FIG. 1'7.
  • FIGS. 13 through 16 illustrate one embodiment of a two-partite connection in accordance with the present invention, generally designated by reference numeral 201] which is shown in use in FIG. 17, though it could be used also with all other embodiments of the present invention.
  • Each plug-type connection 200 includes a plug-type connector member generally designated by reference numeral 210 which consists of a head portion 211 adjoined by a shank portion 212 interrupted by an annular groove 213. At the end of the shank portion 212 opposite the head portion 211 is provided a chamfered end portion 214 or the like.

  • the bent back portion 222 is provided with a circularaperture 224 of a diameter slightly larger than the diameter of the shank portion 212 of the plug member 2111.
  • the base body 221 ' is provided with a circular opening 223 continuing in an elongated channel 226 that terminates in a semi-circular section 222.
  • the semi-circular section 227 is substantially coaxial to the circular aperture 224 and has a'radius' of curvature about equal to or slightly larger than half the diameter of the reduced shank portion 212' formed as a result of the groove 213 in the connector member 2111.
  • the dimension 0, corresponds approximately to the thickness'of two structural parts, i.e., to the thickness of a plate member 150 and of a profile member 110, the two being of identical thickness.
  • the plug member 210 is inserted through two aligned apertures 111 in the plate member 1311 and profile member 110 whereupon the locking member 220 is placed over the projecting end portion 214 by extending the latter through aperture 22!, and thereafter displacing the locking member 220 in the direction of arrow F (FIG.
  • FIGS. 18 through 20 illustrate a modified locking member in accordance with the present invention and generally designated by reference numeral 230 which is operable to cooperate with the plug-type connector member 210, though a plug-type member generally designated by reference numeral 240 and illustrated in FIG. 21 is preferred in some applications.
  • the locking member 230 includes a base body 231 provided with an elongated channel 236 terminating in a semi-circular end section 237. At the right end, as viewed in FIGS. 18 through 20, the base body 231 is adjoined by an upright actuating surface 238 disposed at substantially right angle to the base body 231 while a bent-back part 232 is connected with the base body 231 by way of connecting portion generally designated by 233.
  • the bentback part 232 is provided at the left end thereof, as viewed in FIGS. 18 through 20, with a relatively large circularly-shaped recess 234 and is of approximately undulated shape, with the major portion of an undulation extending in the direction toward the base body 231 and the end portion 232' extending away from the base body 231.
  • the channel 236 is open at the left end thereof by way of the flared wall portions 239 passing over into channel 236.
  • a plug-type member 210 or 240 is inserted with its shank portion through aligned apertures of two standard structural parts.
  • the plug-type connector member 240 which, similar to connector members 210, also includes a head portion 241 and a shank portion 242 as well as an end portion 244,,for instance, chamfered or curved, and a groove 243, differs from member 210 by the provision of an additional groove 245 for purposes to be. explained more fully hereinafter.
  • An important feature of the locking member 230 in accordance with the present invention is the configuration of the base body 231 as illustrated in FIG. 19 which is not flat but instead has two sections 231a and 231b of unequal length and disposed slightly angularly to each other. More particularly, the section 23 is extending over a length a, slants in the direction toward the bent-back portion 232while the shorter section 23lb of a length b slants away from the bent-back portion 232.
  • this arrangement means that a greater force is necessary for disassembling the connected members since the shorter path b having a greater slope requires a greater specific force to overcome the frictional locking effect of the bent-back part 232, 232 than the frictional force produced in conjunction with the more gradual slope of the part 231a.
  • a plug-type connector member in order to facilitate assembly, it may be desirable to preassemble a plug-type connector member to a plate by anchoring the former in the latter.
  • This can be readily done by the use of the flaring tool generally designated by reference numeral 300 (FIG. 22) which includes an internal bore 301 of a dimension g at least equal to or slightly larger than the dimension f of the shank portion of the plug-type connector member 240 in FIG. 21.
  • a sharp, pointed working surface 302 of annular configuration is formed by the beveled surfaces 303 and 304 which may be hardened in any suitable manner.
  • the dimension 2 of the groove 245 must, of course, be only .a fraction of the thickness of a structural part or plate and should be located in such a manner as to be within the central area of the thickness of such part, i.e., the distance d should be between one-third and one-half the thickness of such standard structural part.
  • FIGS. 18-23 Further details of the two-partite connection of FIGS. 18-23 are described in detail in my co-pending application Ser. No. 872,7l5,'filed Oct. 30, 1969, entitled Detachable Two-Partite Connecting Arrangement, the subject matter of which is incorporated herein by reference to the extent necessary.
  • FIG. 24 illustrates a bed generally designated by reference numeral 800 which is also assembled utilizing standard structural parts described in connection with FIGS. 1 through 12. More particularly, profile members 110 are interconnected with each other at the four corners of the bed by suitably shaped plates 130. Additionally, the parts of the angle members 110 disposed at right angle to the plate members 130 are connected with each other by a flat right angle iron 810.

  • the bracket members 820 are necessary to prevent collapse of the frame due to the large number of coil springs 830 resiliently suspending the resting surface 840, properly speaking, in the frame.
  • the particular spring suspension of the present invention assures the utmost comfort since the fabric 840 is held taut and permits it to yield only slightly in an orthopedically correct manner to adapt itself to the contours of the body.

Moreover, the entire assembly can be embedded in concrete, especially in vibrated concrete, thereby increasing the rigidity of the building. Since the apertures 111 can be realized in a simple manner with extreme accuracy, the resulting structure will be true in all cases and any errors can be avoided.
