    专利说明:

    The invention relates to a climbing rung for ascent systems, e.g. Masts, such as power poles or the like., With a mounting portion, a tread shaft and an outer boundary part. Usually masts, such as pylons (power poles) or the like ascent systems (such as on roof structures) are equipped with risers, at least partially as so-called "safety risers". may be formed according to EP 577 587 Bl. These risers are e.g. either on a mast handle (corner handle) or on a separate climbing tree, which is connected to the actual mast (see, for example, AT 3748 Ul, but also AT 9403 Bl and AT 505 934 Ul) mounted. In general, however, the most diverse types of profiles for the attachment of the riser can be used here.
    It is also common in the lower floor area of power poles, above a predetermined height, e.g. about 3m, no risers to install, so as to prevent unauthorized persons can easily climb onto the mast. For the same reason, for example, it is also preferably provided for a rope attached permanently to the mast to the lower end at a greater height, e.g. 2.5m to 3m, to fix above the ground, cf. AT 513 136 bl.
    Then, when work on such a mast are to be carried out, the assembly teams bring climbing aids, such as ladders, which are leaned against the mast, so as to reach the bottom risers and the lower ends of the rope. However, this bringing along and putting up voluminous, bulky ascent aids is cumbersome, expensive and moreover not to the desired extent safe, as the ladders or the like. Tipping aids can tip over or fall over.
    The object of the invention is therefore to enable a simple, rapid ascent of authorized persons to ascension systems, without the bringing along and using such complex and insecure, bulky ascent aids is necessary. In other words, it should be an additional ascent help are proposed, which can be used instead of the mentioned ladders or the like. Climbing aids, and can be easily and quickly assembled and disassembled again.
    For this purpose, the invention provides a climbing rung as stated above, which is characterized in that the fastening portion is designed as a plug-in part, which is adapted for releasable insertion into a receiving device on the ascent system.
    The invention thus provides a special climbing rung, a "plug-in rung". before, which can be mounted in a simple manner by a plug-in movement and removed again by a pull-out. The assembled mating rungs can thus form a kind of ladder, similar to the usual climbing rungs on a mast or climbing tree. By a corresponding shape of the male part of the plug-in sprouts and the receiving device can further be easily counteracts a false structure. On a mast corner post or climbing tree are about the above height of about 3m from the ground (or existing construction, such as concrete base, etc.) or over the entire height recordings or openings attached, and in alignment with these recordings or Openings can moreover be fitted with their own receiving units-either temporarily or permanently-so that they can later releasably fix the plug-in sprouts by simply plugging them in during assembly, directly when climbing the mast. In this case, a single-handed assembly is preferably provided or possible.
    The invention also relates, according to a further aspect, to a receiving device for the plug-in rung, which can either be attached permanently to the ascent system or else can also be mounted only temporarily. Depending on the design of the plug-in part of the plug-in rung, the receiving device can be designed as an elongate guide part, for example in the form of an optionally hollow bolt, with a longitudinal opening for the plug-in part of the riser rung. The mentioned guide part can be formed by a fixedly mounted guide profile. As a receiving device but also just a hooking opening for inserting a hook-shaped plug-in part of the riser be provided. In this case, a Anlageplat te is preferably in the assembled state, for. on the mast or climbing tree etc. over a more or less large area firmly and thus provides a sufficient snapshot for the fixation of the mullion. A further advantageous possibility is to use the plug-in part as e.g. form pocket-shaped plug-in receptacle for the screw head of the screw-receiving device, wherein between the riser (or corner post) and the actual screw head a constriction is provided for pushing the plug-in receptacle.
    On the other hand, the plug-in rung can simply be inserted with an elongate plug-in part into a longitudinal opening or bore of the receiving device and held there by a friction fit. This is already conceivable with a cylindrical plug-in part and a corresponding cylindrical opening or bore, an improvement can be achieved by an at least partially conical design of plug-in part and opening or bore. For avoiding unwanted loosening of the male part of the receiving device and thus falling out of the riser, it is advantageous if the male part has a securing element for its temporary securing to the receiving device. The securing element can be realized in principle in many ways, such as by means of a Sicherungssplints, which is inserted through mutually aligned transverse bores in the receiving device and the male part, or by a simple resilient detent, e.g. Ball catch, whereby the force of the detent spring must be overcome to release (and previously to plug in) the plug-in rung.
    It is particularly advantageous if the plug-in part, at least in its inserted into the receiving device state relative to this receiving device for securing is rotatable.
    The securing element can be provided with respect to an efficient force or torque transmission in the end region of the plug-in part facing away from the tread-surface shaft.
    Of particular advantage in terms of handling is when the
    Securing element by a locking element, e.g. a radial latching projection is formed, which cooperates with a corresponding latching element, e.g. a latching recess is arranged on the receiving device. It is not absolutely necessary to accomplish the locking by means of springs, but it can simply a relative movement between the male part and receiving means are provided for locking.
    In order to facilitate the alignment during insertion of the male part and the subsequent locking, it is further favorable if the radial locking projection at the same time forms a guide nose for cooperating with a guide groove of the receiving device during insertion of the male part. For latching or securing by latching of the latching projection or the guide nose in a corresponding recess, the plug-in rung after its insertion by, for. rotated a quarter turn or a half turn to bring the projection or the guide nose with the recess in alignment. Thereafter, the latching takes place by a short-stroke backward movement in the sense of loosening the plug-in rung from the receiving device. This snapping may be favored in terms of motion guidance if it is locked by a spring, e.g. on the riser, is supported. Accordingly, it is also advantageous if a helical spring is arranged on the plug part, abut the two ends of attacks. The spring assists in the latching movement, and the plug-in rung is held in the latched position by the spring. If the mating rung is to be released, the latching must be released against the spring force, with a corresponding backward movement against the action of the spring and a rotation, e.g. by 90 ° or 180 ° or a predetermined other angle, after which the plug-in rung - further supported by the spring - can be pulled out of the receiving device and disassembled.
    If the latching fails, the spring serves as an additional safeguard in that it automatically pushes the plug-in rung out of the receiving device, whereby it can be seen that the plug-in rung is not securely plugged in. In the preferred case, the spring even pushes the plug-in rung completely out of the receiving device, so that it falls from the mast or climbing tree.
    The coil spring can also be arranged in the mounted state of the male part within the receiving device, so that it is arranged protected, and it can rest in this mounted state at a belonging to the receiving device rear stop. On the other hand, it is advantageous if a front stop for the spring is formed by a collar or a shoulder which separates the male part from the tread surface shaft.
    Furthermore, it is expedient if a rear stop on the male part is formed by a radial projection. The radial projection may be annular, but it may also be only locally, e.g. in tongue form; It is also possible to provide a plurality of such local radial projections circumferentially spaced from each other. It is only important that the spring is also retained in the unassembled state, to prevent their falling from the male part.
    A particularly advantageous embodiment is characterized in that the latching projection on the plug-in part at the same time forms the rear stop for the coil spring.
    As regards the receiving device for the mating rung, it may be formed by a simple guide profile, which can be fixed permanently, for example by welding, on the ascent system such as mast or climbing tree.
    On the other hand, in view of releasably attaching the receiving means, the guiding part may also be replaced by e.g. hollow screw, which can be removably mounted using a nut (and possibly washer) on the ascent system or climbing tree.
    The guide part may have a rear recess as a catch for the latching element of the plug-in part, wherein, as mentioned, the latching element is preferably formed by a guide nose. This guide nose slides when inserting the male part of the
    Plug rung by a guide groove which is preferably provided in the guide part over its length.
    The invention will be explained below with reference to particularly preferred embodiments, to which it should not be limited, and with reference to the drawings. In detail, in the drawing:

    In Fig. 1, a climbing tree 1 is exemplified by an ascent system and partly diagrammatically illustrated, this tree 1 to a not further illustrated mast, namely power or line mast or the like., Belongs to this, for example, at a corner handle or attached to a cross bar, by means of clamping structures 2. With regard to such a clamp construction 2 for a separate climbing tree 1, reference may be made, for example, to AT 3748 Ul and AT 9403 Ul, such a climbing tree solution with clamp fastening being chosen especially if attachment of climbing rungs directly to the mast, e.g. on a mast corner handle, is not allowed. In the case of an attachment directly to a mast Eckstiel omitted as shown in Fig. 1, the clamping structures 2, i. the angular profile shown would then not illustrate a separate climbing tree, but directly the corner post of the mast. In this respect, it should be understood that when exemplified below by a
    Steigbaum 1 is the speech, always a cornerstalk itself or more generally an ascent system or any profile thereof should also be meant.
    According to Fig. 1, at the riser 1, from a certain height H, e.g. 2.5m to 3m, climbing spars 3 and 3 'permanently attached, said risers 3 and 3' with a simple outer disc-like limitation or slip-off 4 or, in the case of a so-called. &Quot; Safety " -Steigsprosse 3 ', with a helical eyelet 4 'are formed, the latter being designed not only as Abrutschsicherung and limitation, but also as a cable-hanger for a (not illustrated in detail) safety rope. With regard to such a safety riser can be made, for example, to simplify the description of EP 577 587 Bl.
    Below the lowest riser 3 'or 3, i. within the lower height range H, merely receiving apertures 5 are provided in the two legs of the corner post or the climbing tree 1, by means of plug-in risers to be explained in more detail below, simply plug-in bars 6 (see Fig. 2) for the purpose of assembly can be plugged. This assembly is carried out releasably during the rise of a mechanic on the riser 1 when installation work on the mast are performed.
    During the descent, the assembler the Stecksprossen 6, which he has previously simply mounted by plugging, again solve and take away, so that the lower portion H, for example, 3m height turn climbing-free. In this way, on the one hand unauthorized climbing on a pole mast prevented, and on the other hand, the upgrade of an authorized person in a simple manner using the Stecksprossen to be described, without the aid of rope ladders, ladders or the like.
    In Fig. 2A and 2B, a first embodiment of a plug-in rung 6 is now illustrated. This plug-in rung 6 has, for example, a screw-head limiting and slip-off securing part 4 at the outer end of a tread shaft 7 and at the inner end thereof an annular
    Bund 8, which serves as a stop for a coil spring 9, which surrounds a male part 10. At its other end, the coil spring 9 abuts against a rear stop 11 in the form of a radial locking projection 11, which at the same time a guide nose 11 during insertion through one of the openings 5 on the corner stem or tree 1 and by a receiving device 12, for example according to FIG to 3C, is formed. The receiving device 12 is formed in accordance with FIG. 3 in the form of a partially angular guide profile which has a longitudinal slot on the underside, which has a lower recess 11 'of the opening 5 in the profile 1 (see FIG. Aligns and so pushing the plug-in rung 6 of FIG. 2 in the position shown, with the guide lug 11 downwards, allows.
    According to FIG. 3B, the guide profile has on its upper side a step 13 with a latching recess 14.
    In FIGS. 4A and 4B, the plug-in rung 6 according to FIG. 2 is illustrated on the riser 1 by means of the receiving device 12 according to FIG. 3 in a detachably mounted state. It can be seen that the plug-in rung 6 of the right in FIG. 4, front or outer side by the (in Fig. 4 not apparent) opening 5 in the tree 1 and by the aligned longitudinal opening of the guide profile 12 - in the orientation Fig. 2 and 3 - pushed and then rotated by an angle of 180 ° until the locking projection, at the same time guide lug 11, is latched to the top of the receiving device 12 in the recess 14, which happens with the help of the spring 9, which shown in FIG 4 during assembly on the one hand at the corner handle 1, at the front, and on the other hand continues to rest on the collar 8.
    4, a short distance against the force of the spring 9 is shifted to the left to release the plug-in rung 6 so that the latching projection 11 is released from the latching recess 14, after which the position is reached by a corresponding reverse rotation through 180 ° , in which the plug-in rung 6 - with the help of the spring 9 - from the receiving device and from the riser 1 away, as shown in FIG
    Fig. 4 to the right, can be moved and removed.
    The guide profile receiver 12 of FIG. 3 is preferably permanent, e.g. by welding, attached to the riser 1. In a modification therefrom, FIGS. 5A to 5C, in views similar to FIGS. 3A to 3C, show an embodiment of the receiving device 12 in the form of a guide part, which is formed by a hollow screw 15, whose screw head is on the side of the climbing boom 1 facing the fitter is lying, which is inserted through an opening 5 through, and finally on the leg of the angle profile of the riser 1 by means of a nut 16, preferably with the interposition of a washer 17, is fixed, see. Similar to the receiving device 12 according to FIG. 3, the receiving device 12 according to FIG. 5 has a longitudinal opening extending therealong, here with a guide groove 11 '' (see FIG The plug-in part 10 of the plug-in rung 6 according to FIG. 2 with the guide lug 11 from the in Fig. 5A and B right side into the hollow screw 15 - in the orientation shown -einführen.
    As a modification in comparison to the embodiment according to FIGS. 3 and 4, the hollow screw 15 according to FIG. 5 has an upper recess 14 without gradation 13. In the releasable fixation of the plug-in rung 6, see. FIGS. 6A and 6B, according to the insertion of the male part 10 by the receiving device 12 in the form of the hollow screw 15 through turn the plug-in rung, for example, rotated by 180 °, so that the guide nose and the locking projection 11 then engages in the upper recess 14, see , in particular FIG. 6B, very similar to the embodiment according to FIGS. 3 and 4.
    In Fig. 7 a comparison with FIG. 2 modified plug-in rung 6 is shown, in which a male part 10 connects via a shoulder 18 to the front or outer tread shaft 7. The latter has, for example, again a simple flange-limiting part 4 at the outer (front) end as slip-off protection.
    The male part 10 has a rear, smaller diameter portion 10 ', which is bounded by a front stop shoulder 8', which forms a stop for the on this smaller diameter portion 10 'mounted coil spring 9. The rear stop for the coil spring is formed by the guide lug 11, wherein the coil spring 9 so long applied to this guide lug 11, as long as the plug-in rung 6 is not inserted into a receiving device 12, as shown in Fig. 8 -. Also to be explained in more detail Fig. 9A and 9B, where the plug-in rung 6 is illustrated mounted in a climbing tree 1 state.
    In a similar manner, the hollow screw Aufnahmeein-direction 12 is modified as shown in FIG. 8 relative to that of Fig. 5: In particular, in the region of the screw head inside a shoulder 18 'is provided, against which the mullion 6 of FIG. 7 when inserted into the Receiving device 12 with her shoulder 18 abuts, see. also the dashed representation in Fig. 9A and 9B. This inner shoulder 18 'can be clearly seen in particular from FIG. 8D.
    At the rear end, the screw-receiving device 12 also has a shoulder 19 which narrows the longitudinal bore of the hollow screw 15 so as to form a rear abutment for the spring 9 at the diameter-narrower part 10 'of the mullion 6 of FIG. 7, when this plug-in rung 6 is inserted into the receiving device 12, in principle as described above with reference to FIGS. 2, 5 and 6, wherein in comparison to Fig. 7, the guide nose 11 when inserting the plug-in rung 6 in the receiving device 12 by 180 ° twisted down to think is. As a result, the guide lug 11 can be moved through the guide groove 11 '' (cf., except Fig. 8A, in particular Fig. 8E), thus enabling a secure insertion of the plug-in rung 6 into the receptacle. If then the spring 9, which rests until then on the guide lug 11, abuts against the inner shoulder 19 in the bore of the receiving device 12 and screw 15, the guide lug 11 in the guide groove 11 '' can be further moved, whereas the coil spring. 9 now rests against the shoulder 19; the plug-in rung 6 is thus from this time against the force of the coil spring 9 - which is compressed accordingly - a little further to the left, as shown in Fig. 9, moves until the guide nose 11 from the receiving device 12 comes out back, so that a Turning the plug-in rung 6, for example, again by 180 °, is made possible in the position shown in FIGS. 7 and 9 upwards. In this orientation, the guide lug 11 can then engage in a corresponding recess 14 on the rear end side of the screw-receiving device, said recess 14 is particularly well visible from Fig. 8E. This latching takes place when releasing the plug-in rung 6 automatically by the action of the spring 9. In this case, the shoulder 18 on the tread shaft 7 comes back from the opposite her inside the receiving means shoulder 18 'free, as shown in Fig. 9A and 9B is.
    The spring 9 holds the plug-in rung 6 again in the locked position by continuing to bear against the inner shoulder 19 under pressure.
    To remove the plug-in rung 6 from the riser 1, this plug-in rung 6 is in turn simply against the force of the coil spring 9 - as shown in Figure 9 to the left - pressed so that the guide nose 11 is released from the recess 14; Thereafter, the plug-in rung 6 is rotated by 180 ° in order to align the guide lug 11 with the guide groove 11 '', so that then the plug-in rung 6 is pressed under the action of the coil spring 9 from the receiving device 12 and the climbing tree 1 away to the right or final dog can be removed.
    Again, as in the previous embodiments, a mounting or dismounting with only one hand is possible.
    In addition, with regard to the embodiment according to FIGS. 7-9, it should be added that the helical spring 9 is present in the interior of the receiving device 12 when the plug-in rung 6 is mounted so that it is protected in the assembled state, for example against soiling, etc., whereas in the embodiment 2 and 4 and 6, the coil spring 9 is exposed exposed in the assembled state.
    In the embodiments discussed so far, the riser, i. Plug-in rung 6, provided with a simple collar-shaped boundary part 4. Of course, in all embodiments, a safety Einhängö-sen boundary 4 'are provided instead, as is known from EP 577 587 Bl. To illustrate this interchangeability in the present mating rungs, in Fig. 10 and 12 is now a mullion 6 with helical hanger as limiting part 4 ', ie a "safety riser", illustrated. In contrast, in FIG. 13 such a plug-in rung as in FIG. 10, but with a simple flange-shaped limiting part 4, is shown. Both versions have in common that the male part 10 instead of cylindrical or stepped but now is conical; a corresponding cone is screwed in the sleeve-receiving device 12 inside, as it ultimately results from the end view of FIG. 11 with the concentric circles for the bore.
    In use, this plug-in rung 6 as shown in FIG. 10 or 13 simply in the previously mounted on the riser 1 receiving device 12 with the hollow screw 15 (which, moreover, in principle similar to that of FIG. 5 is formed) inserted, with a corresponding firm impressions also according to the conical formations of the male part 10 and bore in the receiving device 12, a correspondingly tight interference fit can be achieved. In this embodiment, therefore, a locking by means of a guide nose or the like is unnecessary, and it is not only a simple construction, but in particular also a simple assembly possible.
    Also, the plug-in rung 6 according to FIG. 14 is exemplified as a safety riser, with a helical hanger loop as a limiting part 4 ', formed. For comparison purposes, a corresponding plug-in rung 6, as shown in FIG. 14, is illustrated in FIG. 15 in a state mounted on a riser 1, wherein, however, there is a simple limiting part 4 in flange form. However, the special embodiment as shown in Fig. 14, namely with a male part 10, which is provided with a thread 21, but is also in the embodiment according to
    Fig. 15 given. The receiving device 12 here has a corresponding inner threaded bore 21 ', so that the plug-in rung 6 according to FIG. 14 or 15 during assembly, for example by means of a few turns, can be mounted and secured.
    Otherwise, the receiving device 12 according to FIG. 15 corresponds to that according to FIG. 5, with the exception that, of course, a latching recess can again be dispensed with.
    In the safety riser rung according to Figures 16A and 16B, a plug-in receptacle 22 in the form of a plug-in pocket with undercut, with a guide opening 23 on the side facing the climbing tree or corner post 1 in the mounted state (see Fig. 18A), is provided. With this slot-shaped guide opening 23, the plug-in rung 6 as shown in FIG. 16 is pushed over a smaller diameter part 15 'of the screw-receiving device 12, as best seen in FIG. 18A. This constriction 15 ', s. Also Fig. 17, can be obtained for example by turning off a portion of the screw head, so as to obtain the desired undercut for the attachment of the pocket-shaped plug-in receptacle 22. In the mounted state according to FIGS. 18A and 18B, the plug-in receptacle 22 can be secured to the screw 15 on the right-hand screw head by means of a securing pin 24, as can be seen in particular from FIGS. 18A and 18B. For this purpose, corresponding aligned openings 24 'are provided on the side parts of the plug-in receptacle 22, s. Fig. 16A.
    In general, however, the plugging of the plug-in receptacle 22 without securing with the locking pin 24 is sufficient.
    In this embodiment, as is apparent in particular from FIG. 17, the receiving device screw 15 has a full cross-section in the shank, instead of the hollow design as in the previously explained embodiments, for example according to FIGS. 5, 8 and 11.
    The pocket-shaped plug-in receptacle 22 is preferably relatively large area in order to achieve a correspondingly large contact surface on the angle flange of the riser 1, so as to climb the mast or general ascent system, when loading the mullion 6 with the weight of a person, a correspondingly stable support on To ensure climbing tree 1.
    An embodiment of a plug-in rung 6, which is impressive by its particularly simple embodiment, is illustrated in FIGS. 19A and 19B in conjunction with FIG. This embodiment is similar in terms of its function to that according to FIGS 16 and 18, in that here too a relatively large-area contact of a flange-shaped mast contact plate 25 of the plug-in rung 6 on the riser 1 in the mounted state (see Fig. 21) is given. In extension of the tread shaft 7 behind this mast bearing plate 25 Einhakteil 26 is provided as a male part 10, which through a simple circular opening 27 (see Fig. 20) (as a receiving device 12) inserted in the angle flange of the tree 1 and there is hooked. As can be seen from FIG. 19, the hooking part 26 can be generally elliptical, the width corresponding to the diameter of the circular opening 27. The mast bearing plate 25 extends in the mounted state, as shown in FIG. 21, comparatively far downwards, so as to ensure a corresponding force or snapshot during the support, as well as in the case of the plug-in receptacle 22 in FIG. 16 and 18th
    Apart from the receiving device 12 according to FIG. 3, all of the receiving devices 12 explained above can be fastened detachably to the riser or corner post 1, whereby these receiving devices 12 can also be removed from the respective post if no assembly or maintenance work is to be expected for a long time whereas, if assembly work is required for several days, they may remain on the mast during those days; In contrast, each of the plug-in sprouts 6 are removed immediately after completion of assembly work and leaving the mast, so as to prevent unauthorized climbing of the mast.
