Definitions

  • ABSTRACT A tubular member, adapted to be a nozzle, is provided [30] Forelgn Apphcatmn Pmmty Data in the region of an open end with a closure cap which Feb. 23, 1971 Germany 2108538 can be placed Over the open end to close i and moved from the open end to expose the same.
  • a nozzle usually being configured as a tubular element one end of which communicates with a receptacle and the other end of which is open and can be closed with a closure, for instance a cap.
  • a closure for instance a cap.
  • Such structures are used for instance on gasoline tanks, on oil tanks, and in many other applications.
  • a prior-art proposal connects the closure cap with the tubular member by means of a chain.
  • the chain is, however, usually very thin in order not to interfere with reasonably easy manipulation of the closure cap, and it has been found that even under normal circumstances these chains will frequently break. When this occurs then there is no longer any connection between the clo sure cap and the tubular member, and experience shows that the closure cap frequently becomes lost after only a short time.
  • this known construction has the further disadvantage that when the closure cap is connected with the tubular member the chain usually hangs down along the tubular member in a relatively large loop, thereby creating the danger that it might be snagged for instance when the arrangement is provided with a transportable container and if for example such a container is'transported while depending from a crane, or under similar circumstances.
  • the chain is relatively weak and becomes snagged, then it becomes torn with the attendant disadvantages.
  • the chain is particularly strong and becomes snagged, then there is a danger that the tubular member, the closure cap or even other elements --for instance parts of the receptacle with which the tubular member communicates might become damaged.
  • one feature of the invention resides in an arrangement of the character here under discussion which, briefly stated, comprises a tubular member or a nozzle having one open end adaptedto communicate with a receptacle, and an other open end.
  • Closure means is provided in the region of the other open end and is displaceable relative to the latter between a first and a second position in which it respectively closes and exposes the other open end.
  • Connecting means connects the closure means with the tubular member against separation therefrom when the closure means is in its second position; this connecting means comprises a first portion connected with and displaceable axially with the tubular member intermediate the open ends thereof, being rotatable about the longitudinal axis of the tubular member.
  • the connecting means further comprises at least one rigid second portion fast with the first portion and with the closure means.
  • the second portion is either in form of a rod-like or a bolt-like member, or it may be in form of a single or two transversely spaced arms.
  • Such a construction has the advantage that contrary to the conventional used chains a breaking of this second portion has become virtually impossible. This means that under all circumstances the closure means will remain connected with the tubular member and a loss of the closure means is reliably avoided.
  • the possibility of axially and rotationally displacing the first portion relative to the tubular member assures that there is no interference with the manipulation of the closure means, that is the securing thereof or removal thereof on the open end of the tubular member, including a construction in which the closure means is to be connected with the tubular member by a threaded connection.
  • a threaded connection of course is advantageous because it permits particularly tight and sealing engagement of the closure means with the open end of the tubular member, so that the open end is reliably and sealingly closed even if the medium which is to be prevented from passing through the open end is particularly thin or even of gaseous character, and even if it is under high pressure.
  • a further advantage of the construction according to the present invention is the fact that the tubular member may be relatively short in its axial extension, so that it projects only by a small distance beyond the receptacle with which it communicates, and is no longer a hindrance as is frequently the case in the prior art. This is especially true if the closure means is to be connected with the'tubular member by means of a screw connection or threadedconnection, and a further advantage of such a connection is the fact that it can be secured or released not only manually but also by the aid of mechanical means or by suitable powered equipment.
  • FIG. 1 is a view, partly in axial section,-of a first embodiment of the invention
  • FIG. 2 is a fragmentary view similar to FIG. 1, but illustrating a somewhat different embodiment
  • FIG. 3 is a somewhat diagrammatic view, partly in longitudinal section, of a further embodiment of the invention.
  • FIG. 4 is a view of the embodiment in FIG. 3 in axial section
  • FIG. 5 is a partially sectioned side view illustrating another embodiment of the present invention.
  • FIG. 6 is a section taken on line VIVI of FIG. 5.
  • FIG. 1 shows an advantageous embodiment of the present invention.
  • the second portion of the connecting means is in form of a rod-shaped or bolt-shaped member which when the closure means is connected with the tubular member, extends substantially coaxially with the tubular member and with the closure means.
  • One section of the rod-shaped member is connected with the inner side of the closure means and the other with the first portion which is in this embodiment accommodated in the interior of the tubular member, extending transversely to the longitudinal axis of the latter and engaging behind a suitable abutment which prevents at least undesirable, but preferably also intentional removal of the first portion through the open end of the tubular member.
  • portions of the connecting means are located in the interior of the tubular member when the latter is closed by the closure means and are thus also protected against damage.
  • This construction in particular can be such that the tubular member is very short, an advantage which very often has been found desirable.
  • the abutment means is in form of a radially inwardly extending circumferential bead located in the region of that open end of the tubular member which is to be closed, and with which the first portion of the connecting means engages.
  • the outer diameter of this first portion and the radial width of the opening bounded by the bead should be so correlated with one another that a removal of the first portion from the interior of the tubular member is impossible even if the first portion is tilted by requisite manipulation of the rod-like second portion.
  • the manner in which the tubular members in question are conventionally manufacture permits the provision of such a bead without any difiiculty and without any significant additional expense.
  • reference numeral 1 identifies the tubular member in toto, which tubular member has a tubular portion 2 an open end of which is to be closed with a closure cap 3.
  • a relatively wide bevel 2a is provided on that end of the tubular member remote from the closure cap 3, so that the tubular member can be readily welded or otherwise connected with a receptacle with which it is to communicate, for instance a tank, a conduit, a pipe or the like.
  • the tubular member 2 is provided with outer threads 2b with which internal threads of the closure cap 3 can mesh so that the cap'3 can be threadedly connected with the tubular member 2.
  • the interior of the closure cap 3 is provided with a sealing ring 30 of a soft or elastically compressible material, for instance rubber or an elastomeric plastic and which, when the closure member or closure cap 3 is in place on the tubular member 2 as shown in" FIG. 1, will sealingly engage both the closure cap 3 and the tubular member 2. Knurling is advantageously provided on the exterior of the closure cap 3 so that the latter can be more readily equipped for rotation.
  • a rod-shaped or bolt-shaped member 4 constituting the first portion of the connecting means.
  • the member 4 is in the illustrated embodiment welded by a welded seam 5 with one of its end portions on the inner side of the closure cap 3. Its opposite end portion is connected with a yoke-like portion of the connecting means, identified with reference numeral 6 and accommodated in the interior of the tubular member 2.
  • the connection between the member 6 and the member 4 is here established by means of a rivet 7.
  • the tubular member 2 is provided with an inwardly extending circumferential annular bead 20 with which the member 6 which is slidable axially of the tubular member 2 as well as being turnable within the sameabuts when it approaches the open end so that it cannot be withdrawn through the latter.
  • the outer dimensions of the member 6 and the inner dimensions of the opening surrounded by the bead 2c are so correlated that even if the member 6 is tilted with the closure cap 3 disengaged from the tubular member 2- it cannot be withdrawn.
  • the tubular member 3 is additionally provided with a further inwardly extending circumferential bead 2d at its opposite axial end from the bead 20, serving the same purpose as thelatter; however, because the member 6 cannot be withdrawn at the end where thebead 2d is located because of the presence of the closure cap 3, this additional bead 2a is not absolutely essential and serves actually more to increase the thickness of the wall of the tubular member 2, a consideration which is important for connecting -for instance by weldingof the tubular member 2 with a receptacle.
  • FIG. 2 is rather like that of FIG. 1, except that in this fragmentary illustration it will be seen that the member 6 is connected with the member 4 not by means of a rivet 7, but by being welded thereto via a weldedseam 8.
  • a screw connection or to connect the members 4 and 6 pivotally, for instance by means of a suitable ball-andsocket joint or the like.
  • a particularly advantageous embodiment of the invention can utilize a pair of arms which are connected on the outer periphery of the closure cap 3 and extend in ,substantial parallelism with one another transversely spaced; these arms extend in substantial parallelism with the longitudinal axis of the tubular member 2 along the exterior of the latter.
  • the member 6 is replaced with an annular member which exteriorly encircles the tubular member 2 being turnable relative thereto as well as being axially displaceable with reference to the tubular member 2, with the free end portions of the arms being connected to this annular member.
  • the various components of the connecting means are located at the exterior side of the tubular member 2, contrary to the embodiments of FIGS. 1 and 2, they are spaced from the outer surface of the tubular member by such a small distance that it is in effect impossible for such components to become snagged. Danger of damage to the arms is therefore not to be expected.
  • the particular advantage of this embodiment is the fact that the cross-section of the inlet or outlet opening in the tubular member 2 is entirely unobstructed, making it impossible for any solids or liquid residues to adhere to the components of the connectingmeans and to either contaminate or partially orcompletely'close (for instance over a period of time) the cross-section of the inflow or outflow opening in the tubular member.
  • An additional advantage of this embodiment is the fact that it is of course very simple in such a construction to effect a threaded connection of the opening of the tubular member 2 after the cap member 3 has been removedwith hose couplings or the like.
  • tubular member 2 it is advantageous for the tubular member 2 to be provided with an abutment, projection, radial flange or the like extending outwardly in the region of the open end so as to prevent withdrawal of the annular member.
  • an annular flange so constructed can serve as the carrier for threads by means of which the closure cap 3 can be threadedly connected to the tubular member 2, and/or by means of which a hose coupling can be secured to it. This means that in such a construction it is not necessary to provide a separate flange or abutment for retaining the annular member because the single flange can perform both functions.
  • the arms are also advantageous for the arms to be releasably connected with the annular member, for instance by means of a pin-and-socket connection or the like.
  • Such a construction has the advantage that in the event of cleaning or repair work to be carried out, the closure cap can be readily removed without danger of damage to either the cap member or the connecting means.
  • the member 4 can be pivotably connected with the member 6 in FIGS. 1 and 2
  • the same pivotable connection can be established between the arms and the annular members surrounding the tubular member 2. This has the advantage that the closure cap can be moved away from the opening laterally of the tubular member 2 to such an extent that the opening is freely accessible and entry of exit of matter from it is entirely unhindered.
  • FIGS. 3 and 4 The embodiment just discussed is illustrated in FIGS. 3 and 4, where it will be seen that the closure cap 3 is of one piece with the two parallel transversely spaced arms 13 which extend alongside the tubular member 2 at the outer surface thereof.
  • the arms 13 need not-be of one'piece with the closure cap 3, but could be separate elements welded thereto or otherwise connected to it.
  • An annular member 14 surrounds the tubular member 2, being turnable about the same as well as being axially slidable relative to the tubular member 2.
  • the free ends of the arms 13 are connected with the annular member 14.
  • Axial movement of the annular member 14 is limited on the one hand by the welded seam in the region of the bevel 2a (the seam is not illustrated) by means of which the tubular member 2 is to be connected to a receptacle, a container, a conduit or the like, whereas in the opposite direction the axial displacement is limited by an abutment which is provided and in which the outer thread 2b for the closure cap 3 is formed.
  • Pivots 15 connect the arms 13 with the annular member 14 so that, when the closure cap 3 has been unthreadedfrom the tubular member 2, it can be pivoted laterally out of the region of the opening of the tubular member 2, as illustrated in FIG. 3, whereas in FIG. 4 the closure cap 3 is shown connected with the tubular member 2.
  • each releasable connection between the annular member or ring and the respective arms is established by a radially inwardly extending projection, or a trunnion, on the end portion of the respective arm, received in a corresponding groove-like depression in the outer circumferential surface of the ring.
  • a radially inwardly extending projection, or a trunnion on the end portion of the respective arm, received in a corresponding groove-like depression in the outer circumferential surface of the ring.
  • the nozzle, the closure cap and the arms (if the same are of one piece with the closure cap) as well as the ring can be made by molding techniques, for instance by casting or injection molding and can be connected without requiring any significant amount of material-removing processing after manufacture.
  • the constituent components in such a manner without ever having to subject them to material-removal treatment, thereby making their manufacture very inexpensive.
  • the riveting or screw threaded connection of individual components is avoided, and of course also the necessary material removal which is required for such connection.
  • the depressions or recesses as well as the projections or trunnions on the arms can be produced as the ring and the arms are being molded, so that it is subsequently only necessary to establish a connection between them in simple inexpensive manner.
  • such a construction is particularly strong so that even under the influence of substantial forces the closure cap cannot be torn off.
  • this latter embodiment willhave groovelike depressions in the outer circumferential surface of the ring which extend from the pivot point of the respective pivotal connections to that axial end of the ring which faces away from the closure cap.
  • each of the grooves or recesses is angled, with the groove having two portions which intersect one another and with the point of intersection constituting the pivot point for the respective pivotal connection.
  • the longer arm or portion of the angular groove should then extend to that axial end of the ring which faces away from the closure cap, and the shorter other arm should extend approximately tangentially with reference to the circumference of the ring.
  • the assembly of the components is as simple as just outlined above, but in addition it is possible after unthreading the closure cap from the tubular member, or nozzles, to move it laterally out of the region of the opening of the nozzle without requiring a complete disconnecting of the closure cap from the nozzle.
  • the cross-section of the opening can be made completely unobstructed by removing the closure cap entirely to one side of the nozzle. It is advantageous if the cross-sectional dimensions of the trunnion of at least one but preferably both of the arms be greater in longitudinal direction of the arm, and smaller in transverse direction of the arm, than the width of the associated groove-like recess, and that the recess has only in the region where the pivot point of the connection is, a width which is slightly greater than the maximum cross-sectional dimension of the'associated trunnion.
  • this construction not only avoids a separation of the closure cap from the nozzle, but at the same time it affords a simple and reliable arresting of the closure cap in a position in which it completely frees the opening of the nozzle and is retained against undesired movement back to a position in which it would partially or completely close this opening.
  • FIGS. 5 and 6 where the tubular member or nozzle, is identified with reference numeral 21 and is for instance welded by means of a welded seam 23 into the bottom wall 22 of a receptacle.
  • receptacle is shown of course by way of example only and not to be considered limiting.
  • the member 21 has a tubular portion 24, the closure cap 25 and an outer annular member or ring 26 encirculing the tubular portion 24.
  • the closure cap 25 is provided with internal threads 250 by means of which it can be threadedly connected with the external threads 24a of the tubular portion 24.
  • a sealing gasket 25b is provided which in i the connected position is pressed by the closure cap 25 against the sealing surface 24b of the tubular member 24, thereby establishing a reliable seal of the opening thereof.
  • the connecting means is here in form of two transversely spaced arms 27 of which only one is visible in FIG. because the other one is concealed by the tubular portion 24, the cap 25 and the visible arm 27. However, it is to be understood that the other arm 27 is connected and arranged in the same manner as that which is visible.
  • Both of the arms 27 are fixedly connected with the cap 25, for instance by being of one piece therewith. Their free end portions are connected with the ring 26 by means of trunnions 27a which in longitudinal direction of the respective arms 27 have a greater length 1 than in direction transversely thereto in which they have a width b.
  • the trunnions 27a extend into angular grooves 28 formed in the outer circumferential surface of the ring 26, and the point of intersection of the two portions of each angular groove constitutes at the same time the pivot point D about which the respective trun nion 27a can pivot.
  • the grooves are of circular cross-section so that the trun nion 27a can be readily turned about the pivot point D; the greatest cross-sectional dimenion of each trunnion 27a, that is in this embodiment the diagonal of the cross-sectional surface of the trunnion 27a, is smaller than the diameter of this circular-cross sectional portion of the respective groove 28.
  • the length of the arms 26 is so configurated that the cap 25 can be pivoted in the direction of the arrow x out of the region of the open end of the nozzle 24.
  • the cap 25 moves to a position laterally of nozzle 24 in which the arms 27 extend approximately normal to the longitudinal axis of the nozzle 2 and in which the trunnions 27a of each arm 27 can be drawn into the portion 28a of the respective groove 28, which extends tangentially in the ring 26 because the width b of the trunnions 27a is slightly smaller than the width of the portion 28a of the groove 28.
  • a radially outwardly directed i'orce is exertedon the cap 25 in the direction of the arrow y, the trunnions 27a are drawn into the arms 2811 so that the cap 25 assumes the position shown in broken lines in H0.
  • cap 25 cannot unintentionally return into its initial position or near its initial position, and only when it has been moved oppositely to the direction of the arrow y, and the trunnions 27a move back into the region D, the cap 25 can be pivoted counter to the direction of the arrow x and be threadedly connected again with the threads 24a of the nozzle 24.
  • the cap 25 in order to establish such a threaded connection or in order to terminate it, it is necessary for the cap 25 to be capable of being turned about the longitudinal axis of the nozzle 24. Because this is prevented by the projections 27a of the arms 27 and the associated grooves 28 with respect to the ring 26, the
  • ring 26 must be capable of turning together with the cap 25 about the longitudinal axis of the nozzle 24, and
  • the portion 28b of the grooves 28 extends from the pivot point D towards that axial end of the ring 26 which faces away from the cap 25.
  • the projections 270 are simply inserted at this aforementioned axial end into the portions 2812 until they reach the pivot points D, at which time they together with the arms and the cap 25 can be pivoted about the pivot point until the cap 25 assumes approximately the broken-line position after which the nozzle 24 can be pushed from below into the ring 26 because the nozzle 24 of course at this time is not yet connected to a receptacle or the like. This, then, establishes a rapid connection in a very simple and timesaving manner and subsequently the nozzle 24 can be connected to a receptacle or the like.
  • an abutment 29 is provided against which the cooperating arm 27 will abut.
  • the abutment 29 is more clearly shown in PK]. 6 and it will be seen that the associated arm 27 cannot be moved past this abutment.
  • HO. 6 shows that the annular member 26 is in contact not over its entire circumference of the tubular member 24, but only at four locations 3b in order to facilitate turning and longitudinal movement relative to the tubular member 24. However, this is of course not necessary.
  • the cap member can be pivoted to the opposite sides of the tubular member, and arrested in either one of the positions thus achieved.
  • the grooves 28 would then have to be of substantially T-shaped configuration, that is the portion 28a would have to be complemented by an additional portion extending in the same orientation but to the opposite side of the portion 281).
  • this is not normally necessary for the purposes of the present inven- Y tion and for an appropriate use.
  • tubular member 24 instead of welding the tubular member 24 to a receptacle or the like, its end remote from that to which the cap member is to be connected can also be provided with internal orv external threads, for engagement with for instance a threaded ring which in turn can then be welded to a container or the like.
  • This has the advantage that only the relatively small threaded ring especially if it is threaded into the interior of the tubular member need be made of a material which can be welded, whereas the choice of material for all other components is entirely free.
  • a container which for instance is made of stainless steel or the like, can be provided with a tubular member, a cap and connecting means of synthetic plastic.
  • a threaded ring has the advantage that the ring can be provided with appropriately long internal threads whereas a container or the like usually has a wall thickness which is too small to provide a properly long internal thread so that it is preferred to establish a welded connection with such a relatively thin wall.
