Definitions

  • the invention relates to a clamp closure 'for releasably connecting the closing flap of cases, writing cases or the like to the main body of such structures, with a spring-containing lower part and an upper part which comes into releasable locking engagement when the upper part and lower part are pressed together with the spring.
  • DE-OS 27 38 122 relates to a clamp closure in which the base plate of the lower part is provided with four openings arranged on a circumference, in pairs enclosing two opposing webs. Furthermore, the lower part of the clamp closure according to DE-PS 27 38 122 has a cap provided with four saddles corresponding to the openings in the base plate, which can be pressed into the cap Openings can be connected to the base plate. Outside the area of the webs, the cap has a partially cylindrical peripheral wall with a lower height than the lugs, the peripheral wall being broken through between two adjacent, closely adjacent lugs up to the cover surface of the cap.
  • the upper part of the clamp closure has a clamping plate which has a circular opening substantially corresponding to the diameter of the cap, an annular projection being provided on the opening edge facing the lower part for pressing in the circumferential projections of the annular spring for latching between the latter and the base plate.
  • the known clamp closure is extremely convenient and reliable to handle in practical use.
  • the four narrow lugs of the cap can break off under extreme stress, so that the connection between the cap and the base plate can be detached or damaged in an unfavorable manner.
  • the present invention is therefore based on the object we 'to form a clamp closure of the type mentioned in such a way that a reliable fastening of the cap on the base part and thus a secure reception of the spring of the clamp closure is ensured.
  • this object is achieved with a clamp closure for releasably connecting the closing flap of cases, writing cases or the like in that the lower part a base plate provided with two grooves arranged on a circular circumference, including two opposing webs, a base plate provided with two lugs corresponding to the grooves, connectable to the base plate by pressing the lugs into the grooves, a slotted in the region of the webs and otherwise having a partially cylindrical peripheral wall Cap and a slotted ring spring with two mutually opposite circumferential projections, which protrude radially in the web areas after assembly of the lower part over the outer circumference of the cap; and that the upper part has a clamping plate with a circular opening substantially corresponding to the outer diameter of the cap, an annular projection being provided on the opening edge facing the lower part for pressing in the peripheral projections of the annular spring and for latching between the latter and the base plate.
  • Preferred embodiments of the invention are characterized in that the lugs on the cap are frictionally held in the grooves of the base plate and / or the cap is connected to the base part by means of the lugs fastened in the grooves of the base part, the latter embodiment being further developed thereby; that the cap is welded by means of the lugs in the grooves of the base part or that the lugs are firmly glued in the grooves.
  • connection area between the base plate and the cap is thus improved in that two almost semicircular grooves are provided in the base plate, into which two approaches of the cap, which are also almost semicircular and corresponding to the shape of these grooves, can be inserted, the circumferential projections of the ring spring located in the cap through the opposite openings protrude from the cap in the cylindrical side wall of the cap between the two, almost semicircular lugs of the cap over the webs of the base plate left between the almost semicircular grooves, whereby the clamping engagement with the clamping plate is made possible.
  • the almost semicircular approaches of the cap are extremely stable and cannot be broken off during normal use, so that a reliable and firm connection between the cap and the base part is achieved.
  • the exemplary embodiment of the base plate 22 shown in FIG. 1 is provided as a lower part for cases for writing instruments, the case provided with the lower part being able to accommodate two writing instruments.
  • the illustrated base plate 22 has a central part 6 and a shoulder-like circumferential edge 8 surrounding the central part 6 up to one side circumferentially.
  • the base plate 22 is provided with two, almost semicircular grooves 14, which are arranged on a circular circumference and include two opposing webs 10, 12, 16 provided, each having a substantially rectangular cross section.
  • FIG. 2 shows a cap 34 which has a peripheral wall, from which two lugs 24, 26, which are also almost semicircular and correspond to the grooves 14, 16, extend perpendicular to the cover surface 33 of the cap 34. Between the almost semicircular shoulders 24, 26, the circumferential wall 32 is broken through on two exactly opposite sides up to the cap surface 33.
  • the circumferential projections 38, 40 of the annular spring 36 shown in FIG. 3 to be inserted into the cap 34 pass through here.
  • the ring spring 36 is not designed as a full ring, but rather perforated at a point 37 of the circumference, so that it can be compressed under forces acting on the circumferential projections 38, 40 so that the circumferential projections 38, 40 can retract inwards.
  • the circumferential projections in the exemplary embodiment shown are chamfered on one side by chamfering 39, 41 from the edge of the annular spring 36 to its end.
  • FIG. 4 shows the lower part composed of the base plate, cap 34 and ring spring 36.
  • the circumferential projections 38, 40 of the ring spring 36 extending out of the cap are clearly recognizable.
  • the lower ends 25, 27 of the lugs 24, 26 are welded firmly in the grooves 14, 16.
  • FIG. 5 A clamping plate 42 of the upper part of the clamping closure according to the invention is shown in FIG. 5, the clamping plate 42 having an essentially circular opening 44 corresponding to the diameter of the cap 34, on the opening edge facing the lower part of which there is an annular projection 46 for pressing in the peripheral projections 38, 40 of the annular spring 36 and for snapping between them and the base plate 22.
  • Embodiment of the clamping plate 42 is essentially semicircular and slightly flattened towards the semicircular circumference, while at the straight end of the clamping plate 42 there is an extension 48 with a smaller thickness than the clamping plate 42, which, like the peripheral edge of the lower part, has sewing eyes 50 is provided, by means of which the upper part and lower part can be sewn together with case material, for example leather or leather-like plastic material.
  • the lower part and the upper part of the clamp closure according to the invention are sewn into a case by means of the sewing eyelets 50 in such a way that the upper part connected to a tab of the case can be firmly pressed onto the lower part so that the peripheral projections 38, 40 are closed Ring spring 36 engages behind the annular projection 46 of the circular opening 44 of the clamping plate 42 of the upper part.
  • the upper part and the lower part are sewn in a corresponding manner into other objects, such as writing folders and the like, in order to likewise use the clamp closure according to the invention.
  • the clamp closure according to the invention can be used for cases of various kinds, for example for writing cases for one or more writing instruments, for which purpose the lower part illustrated with insertion grooves 56, 58 provided on the side facing the upper part, which serve to receive the clamping spring of the writing instruments, the thickened of which End also engage in the openings 16, 62 shown, are provided; in a different design of the lower part, however, the clamp closure according to the invention. can also be used for credit card cases, coin cases and key cases as well as wallets and writing cases or the like.
