Description

[0001] The present disclosure relates to an additional element for a ladder, in particular a ladder tip. background

[0002] Ladders are used in a wide variety of situations to reach a higher object that would not be accessible using purely human capabilities such as one's own height and arm length.

[0003] Especially in fruit tree pruning, where workers such as harvest helpers sometimes have to work at considerable heights, the stability of such a ladder is indispensable in order to guarantee occupational safety and to provide workers with a safe place to work at height.

[0004] Common solutions to ensure a secure footing for the ladder on soft surfaces (such as a meadow) include so-called ladder spikes, which are usually attached to the lowest rung (also called crossbar) or to the stile of the ladder and are inserted into the ground with an elongated, often pointed end, so that the ladder cannot slip on the ground or on the meadow / grass.

[0005] However, existing ladder tip solutions often suffer from the problem that the clamping mechanism used to attach the tips to the ladders / rung sizes can easily jam when adjusting to the appropriate rung size and / or when locking the mechanism, thus hindering a secure attachment of the ladder tip to the respective rung. Furthermore, some existing ladder tips do not offer any way to adapt to different rung / stile cross-sections.

[0006] In view of the disadvantages described above, and starting from the prior art described above, it is an objective of the present application to provide an additional element for a ladder, in particular a ladder tip, with which the aforementioned disadvantages are avoided. Summary

[0007] The present disclosure relates to an additional element for a ladder, in particular a ladder tip.

[0008] In particular, to solve the aforementioned problem, an additional element for a ladder according to claim 1 is proposed. The dependent claims relate to some exemplary preferred embodiments.

[0009] According to exemplary aspects, an exemplary additional element for a ladder is proposed, comprising: a main section extending along a longitudinal direction, a projection provided on the main section and extending perpendicular to the longitudinal direction of the main section, a clamping section movably connected to the elongated main section, wherein the clamping section and the projection are configured to provide a portion of the ladder between the clamping section and the projection, and a locking section configured to generate a clamping force on the portion of the ladder by means of the clamping section and the projection.

[0010] The exemplary additional element can be advantageously further developed, for example, by designing the locking section to push the movable clamping section in the direction of the projection.

[0011] The exemplary additional element can be advantageously further developed, for example, by the clamping section and the projection being further arranged to provide the part of the conductor in a perpendicular direction to the longitudinal direction of the main section next to the main section.

[0018] The exemplary additional element can be advantageously further developed, for example, by having the clamping section have a through-opening through which the main section extends and by means of which the clamping section is movable in the longitudinal direction of the main section along the main section.

[0019] The exemplary additional element can be advantageously further developed, for example, by providing the through-opening of the clamping section at least partially in the first sub-section of the clamping section and at least partially in the second sub-section of the clamping section.

[0020] The exemplary additional element can be advantageously further developed, for example, by designing the through-opening as an elongated hole.

[0021] The exemplary additional element can be advantageously further developed, for example, by having a first subsection extending perpendicular to the longitudinal direction of the main section and a second subsection extending in the longitudinal direction of the main section, wherein the first subsection and the second subsection of the projection can be brought into contact with the part of the ladder.

[0022] The exemplary additional element can be advantageously further developed, for example, by extending the second subsection of the projection in the direction of the clamping section.

[0023] The exemplary additional element can be advantageously further developed, for example, by the main section having a cylindrical shape and a thread at its first end with which the locking section engages, wherein the clamping section is arranged between the locking section and the projection on the main section.

[0030] The following section describes examples and embodiments of the present disclosure in detail with reference to the accompanying figures. Identical or similar elements in the figures may be designated by the same reference numerals, but sometimes they may be designated by different reference numerals.

[0031] It should be emphasized that the subject matter of the present disclosure is in no way limited or restricted to the embodiments and their features described below, but also includes modifications of the embodiments, in particular those which are covered by modifications of the features of the described examples or by combining one or more of the features of the described examples within the scope of protection of the independent claims.

[0032] Fig. Figure 1a shows an exemplary representation of an exemplary conductor tip 100 from the state of the art in a perspective view.

[0033] The main section 110 is shown first, which can be formed from a base element 111. The base element 111 may have, for example, a tapered end 112 at its first end, which is located longitudinally along the main section 110. Furthermore, the base element 111 may have, for example, a thread 113 / a threaded section 113 at its second end, which is opposite the first end 112 in the longitudinal direction of the main section 110 (or the base element 111). This thread 113 may be designed to engage, for example, with an element with an internal thread (such as a nut or a star knob, etc.).

[0034] Furthermore, the exemplary conductor tip 100 from the prior art can have a projection 120 on the main section 110, in particular on the base element 111 of the main section 110, which extends perpendicular to the longitudinal direction of the main section 110 from the main section 110 or from the base element 111. The exemplary projection 120 can be firmly connected to the main section 110 or to the base element 111 of the main section 110.

[0035] Furthermore, the exemplary conductor tip 100 from the prior art can have a clamping section 130, which can be designed, for example, in a manner comparable to the exemplary projection 120, but instead of the fixed connection to the main section 110, for example, it can have a through-hole 131 through which the main section 110 or the base element 111 can pass, so that the exemplary clamping section 130 is located between the thread 130 and the projection.

[0036] This allows a locking section to engage with the thread 113 of the main section 110 (not explicitly shown here, see for example [reference]). Fig. 2), which may be designed, for example, as a nut or as a star knob or similar, move / push the clamping section 130 in the direction of the projection 120 and thus, for example, a crossbeam (also called a transverse beam) or a stile of an exemplary ladder (not shown here, see for example the Fig. 5a and Fig. 5b) clamp between the clamping cut 130 and the projection 120 and thus attach the conductor tip to the exemplary conductor.

[0037] The through-hole 131 of the exemplary clamping section 130 has the disadvantage that, when moving along the longitudinal direction of the main section 110 or the base element 111 of the main section 110, the clamping section 130 can jam against the main section 110 due to, for example, a very small clearance / distance between the surface of the through-hole 131 and the outer surface of the base element 111, so that a desired clamping force for fastening the conductor tip 100 to the exemplary conductor (especially to the stile or crossbar of the exemplary conductor) is partially not possible, since the jamming occurs before the desired clamping force is reached.

[0038] This occurs particularly because the force is introduced into the clamping section 130 by the locking section significantly offset from the area of ​​the clamping section 130 that clamps the beam / crossbeam with the projection 120.

[0039] This causes the clamping section 130 to tilt, and the through-hole 131 comes into contact with the outer surface of the main section 110 / base element 111. Since the clamping section 130 is typically made of a sheet metal only a few millimeters thick (e.g., 5 mm), the available guide length for potentially guiding the clamping section 130 along the main section 110 to prevent tilting or at least counteract it to some extent is insufficient. As a result, the clamping section 130 jams against the main section 110, preventing the maximum possible clamping force from being applied to secure the conductor tip 100 to the conductor in question.

[0040] Fig. Figure 1b shows the exemplary conductor tip 100 from the state of the art according to Fig. 1a in lateral view of the main section 110 and the projection 120 as well as the clamping section 130 with through bore 131.

[0041] This refers to what is already in Fig. As described in section 1a, it is only pointed out here once again by way of example that a clamping section 130 guided through the through bore 131 shown here by way of example can very easily jam against the main section 110, since the force introduction into the clamping section 130 by the locking section is laterally offset to the area of ​​the clamping section 130 used for clamping the exemplary conductors.

[0042] To counteract this disadvantage, an exemplary additional element 200 for a ladder, in particular a ladder tip, is proposed, as described in the following figures.

[0043] Fig. Figure 2 shows an exemplary representation of an exemplary additional element 200 for an exemplary ladder 300, which is not explicitly shown here and for which the following are examples Fig. 5a and Fig. 5b is referred to.

[0044] The exemplary additional element 200, for example, has a main section 210 which can extend along a longitudinal direction, and an exemplary projection 220 which is provided on the main section 210 and can extend perpendicular to the longitudinal direction of the main section 210.

[0045] Furthermore, the exemplary additional element 200 can have a clamping section 230 which is movably connected to the elongated main section 210 (in particular to a base element 211 of the main section 210), wherein the clamping section 230 and the projection 220 can be configured to provide a part of the conductor between the clamping section 230 and the projection 220.

[0046] Furthermore, the exemplary additional element 200 can have a locking section 240 which is designed to generate a clamping force on the part of the conductor by means of the clamping section 230 and the projection 220 and thus to fasten the exemplary additional element 200 to the exemplary conductor.

[0047] If, for example, the ladder with the exemplary, attached additional element 200 is placed on a soft surface such as soil, part or a large part of the base element 211 of the main section 210 sinks into the soft surface and can thus secure the ladder against slipping. For the base element 211 to sink into the soft surface, a tapered end 212 / conical end 212 of the base element 210, which is opposite the end of the base element 211 with the locking section 240, can also be advantageous.

[0048] Furthermore, it may be advantageous if the locking section 240 is designed to push the movable clamping section 230 in the direction of the projection 220 in order to generate the desired clamping force between clamping section 230 and projection 220 for clamping the conductor (or the crossbeam or stile of the conductor).

[0049] Furthermore, it may be comparable to the conductor tip 100 from the state of the art, as it is in Fig. 1a and Fig. 1b is described if the clamping section 230 and the projection 220 are further configured to provide the part of the conductor in a perpendicular direction to the longitudinal direction of the main section 210 next to the main section 210 and to clamp the part of the conductor (directly) next to the main section 210 or the base element 211 of the main section 210 (see in particular the Fig. 5a and Fig. 5b).

[0050] Fig. Figure 3a shows an exemplary representation of the exemplary clamping section 230 according to Fig. 2 in perspective view.

[0051] The exemplary clamping section 230 can have a first subsection 231 extending perpendicular to the longitudinal direction of the main section 210 (or to the longitudinal direction of the base element 211 of the main section 210) and which can be brought into contact with the conductor, and a second subsection 232 extending in the longitudinal direction of the main section 210 (or in the longitudinal direction of the base element 211 of the main section 210) and which can be brought into contact with an outer surface of the main section 210, in particular with the outer surface of the base element 211 of the main section 210, as is also shown by way of example in Fig. 2 is shown.

[0052] For example, the second subsection 232 of the clamping section 230 can be further configured to bear against the outer surface of the main section 210 / base element 211 of the main section 210 when the portion of the conductor is pressed towards the projection 220 by the clamping section 230. In particular, the second subsection 232 of the clamping section 230 can be brought into contact with an outer surface of the main section 210 that is opposite the first subsection 231 of the clamping section 230.

[0053] The second subsection 232 of the clamping section 230 provides the clamping section 230 with additional support on the main section 210 against tilting of the clamping section 230, even if the force is introduced into the clamping section 230 by the locking section 240 (see also Fig. 2) offset from the actual clamping of the ladder (the stile / the crossbar of the ladder) between clamping section 230 and projection 220.

[0054] This allows the first subsection 231 of the clamping section 230 to advantageously remain in an orientation extending essentially perpendicular to the longitudinal direction of the base element 211 of the main section 210, despite a force being introduced by the locking section 240, and thus enable a desired clamping force between clamping section 230 and projection 220 for fastening the exemplary additional element 200 to the exemplary ladder.

[0055] Furthermore, the clamping section 230 can have a third subsection 233, which begins at the end of the first subsection 231, which is opposite the main section 210, and extends in the longitudinal direction of the main section 210 or the base element 211 of the main section 210. In particular, the third subsection 233 of the clamping section 230 can extend in the same direction as the second subsection 232 of the clamping section 230.

[0056] This allows the clamping section 230 to advantageously have a projecting (third) subsection 233, which, for the actual clamping process of the conductors between clamping section 230 and projection 220, can advantageously hold the clamping section 230 in its position relative to the conductor or parts thereof (such as a beam or crossbeam) until the locking section 240 exerts a force on the clamping section 230 and it thereby remains in its position relative to the conductor.

[0057] Furthermore, the third subsection 233 of the clamping section 230 advantageously ensures that the exemplary additional element 200 cannot easily move away from / be detached from the part of the conductor that is clamped between the clamping section 230 and the projection 220 in a direction perpendicular to the longitudinal direction of the main section 210. For this purpose, the clamping section 230 can have a C-shape (the projection 220 can, for example, be designed as an L-shape or also as a C-shape) and thus connect the part of the conductor to the exemplary additional element 200 by means of a positive-locking connection in addition to a force-fit connection.

[0058] For this purpose, it is of course advantageous that the third subsection 233 of the clamping section 230 can extend in the direction of the projection 220 from the first subsection 231 of the clamping section 230.

[0059] For the provision of the clamping section 230 on the main section 210 of the additional element 200, it can be advantageous for the clamping section 230 to have a through-opening 234 through which the main section 210 extends and by means of which the clamping section 230 is movable in the longitudinal direction of the main section 210 along the main section 210, as is also the case in Fig. 2 and Fig. 5b is evident.

[0060] The through-opening 234 of the clamping section 230 can, for example, be provided at least partially in the first sub-section 231 of the clamping section 230 and at least partially in the second sub-section 232 of the clamping section 230. It should be noted, however, that the through-opening 234 can also be provided exclusively in the first sub-section 231 of the clamping section 230, in which case the through-opening 234 in the first sub-section 231 of the clamping section 230 can, for example, advantageously extend to the second sub-section 232 of the clamping section 230.

[0061] In both exemplary design possibilities, it can be advantageous for the through-opening 234 to be designed, for example, as an elongated hole 234.

[0062] Fig. Figure 3b shows the exemplary clamping section 230 according to Fig. 3a in side view (Figure a)) and in bottom view (Figure b)).

[0063] This should refer to the explanations regarding Fig. 3a is referred to and the shape of the clamping section 230 is briefly discussed again here, which is essentially a C-shape or U-shape (see in particular illustration a)) and can be formed by the first subsection 231 of the clamping section 230 as well as the second and third subsections 232, 233, each on opposite sides of the first subsection 231.

[0064] In an inner area of ​​the C-shape / U-shape, the part of the ladder, for example the stile or the crossbar, can be positioned and a clamping force can be generated between the clamping section 230 and the projection 220 by the locking section 240, so that the exemplary additional element 200 is securely attached to the part of the ladder.

[0065] The through-opening 234, as shown again by way of example in figure b), can be designed as an elongated hole and extend from the first subsection 231 of the clamping section 230 to the second subsection 232 of the clamping section 230 or even into the second subsection 232 of the clamping section 230.

[0066] Fig. Figure 4a shows an exemplary representation of the exemplary main section 210 and the exemplary projection 220 according to Fig. 2 in perspective view.

[0067] The main section 210 can be compared to the conductor tip 100 according to Fig. 1a and Fig. 1b, a base element 211 which, at its first end provided in the longitudinal direction of the main section 210, may, for example, have a tapered end 212, for example, a conically tapered end 212. Furthermore, the base element 211 may, at its second end opposite the first end 212 in the longitudinal direction of the main section 210 (or of the base element 211), for example, have a thread 213 / a threaded section 213 (for example, a metric thread, for example, of size M12), which may be provided, for example, with the locking section 240 (for example, a nut or a star knob, etc., see for example). Fig. 2) to be engaged. This locking section 240 can then exert a force on the clamping section 230 via the engaged thread 213, thus generating a clamping force between the clamping section 230 and the projection 220 to clamp the part of the conductor.

[0068] Furthermore, the exemplary additional element 200 can have a projection 220 on the main section 210, in particular on the base element 211 of the main section 210, which extends perpendicularly to the longitudinal direction of the main section 210 from the main section 210 or from the base element 211. In particular, the projection 220 can have a first subsection 221, which extends perpendicular to the longitudinal direction of the main section 210, and a second subsection 222, which extends in the longitudinal direction of the main section 210, wherein the first subsection 221 and the second subsection 222 of the projection 220 can be brought into contact with the part of the ladder, as is the case, for example, in Fig. 5a and Fig. 5b is shown.

[0069] The second subsection 222 of the projection 220, similar to the third subsection 233 of the clamping section 230, can advantageously ensure that the exemplary additional element 200 cannot easily move away from / be detached from the part of the conductor that is clamped between the clamping section 230 and the projection 220 in a direction perpendicular to the longitudinal direction of the main section 210. For this purpose, the projection 220 can, for example, be designed as an L-shape (or also as a C-shape) and thus connect the part of the conductor to the exemplary additional element 200 by means of a positive-locking connection in addition to a force-fit connection.

[0070] Here too, it is advantageous that the second subsection 222 of the projection 220 extends in the direction of the clamping section 230 from the first subsection 221 of the projection 220.

[0071] Furthermore, the exemplary projection 220 can be firmly connected to the main section 210 or to the base element 211 of the main section 210, for example by means of a material-bonded connection that extends along the longitudinal direction of the main section 210 on the base element 211. However, it should be noted that a form-fit and / or force-fit connection can also be used to attach the projection 220 to the main section 210 or to the base element 211 of the main section 210.

[0072] Furthermore, as shown here by way of example, the main section 210 or the base element 211 of the main section 210 can have a cylindrical shape (for example, made of a round metallic material) and have at its first end the thread 213 / threaded section 213 with which the locking section 240 can be engaged, wherein the clamping section 230 can be arranged between the locking section 240 and the projection 220 on the main section 210. For example, steel can be used as the round material, which can be galvanized (this can be advantageous, for example, against corrosion of the steel and against seizing of the locking section 240 on the thread 213).

[0073] Due to the cylindrical shape of the base element 211 of the main section 210, the clamping section 230 can advantageously not only be moved in the longitudinal direction of the main section 210 / in the longitudinal direction of the base element 211 of the main section 210, but can also be rotated around the longitudinal axis of the main section 210 / be rotatable.

[0074] This can be advantageously used to adapt the clamping area between the clamping section 230 and the projection 220 to the corresponding dimensions of the part of the ladder (for example, the cross-section of the stile or the cross-section of the crossbeam) by rotating the clamping section 230 relative to the projection 220, thus achieving an even better fixation of the exemplary additional element 200 to the exemplary ladder (see in particular Fig. 5a).

[0075] Fig. 4b shows the exemplary main section 210 and exemplary projection 220 according to Fig. 4a in side view (Figure a)) and in top view (Figure b)).

[0076] This refers to the explanations regarding Fig. 4a is referenced and, for the sake of better illustration of the size relationships of main section 210 and projection 220, a side view (see illustration a)) and a top view of the thread 213 / thread section 213 in the direction of projection 220 (see illustration b)) are shown.

[0077] Fig. Figure 5a shows an exemplary representation of the exemplary additional element 200, which is attached to an exemplary traverse 310 (or cross traverse 310) of an exemplary ladder 300, in a perspective view.

[0078] This section further clarifies how the exemplary additional element 200 can be attached to an exemplary crossbeam 310 of an exemplary conductor 300, in particular by rotating the clamping section 230 relative to the projection 220, in order to adapt the exemplary additional element 200 to the existing cross-section of the exemplary crossbeam 310. This results in an even better attachment of the exemplary additional element 200 to the exemplary conductor 300.

[0079] Cross-sections of crossbeams or stiles, for example, with a height of 40 mm x a width of 20 mm to a height of 60 mm x a width of 25 mm, are conceivable and can readily be used with the exemplary accessory element 200 to attach it to the ladder. However, it should be noted that the exemplary accessory element 200 can also be designed for attachment to other cross-sections, for example, cross-sections with a height of 20 mm to 100 mm and a width of 10 mm to 40 mm, depending on the design of the ladder or the crossbeams and stiles and the requirements for the accessory element 200.

[0080] Advantageously, the exemplary additional element 200 can be connected to the ladder 300 near its feet 350 to ensure a secure footing for the ladder 300 on soft ground (e.g., grass). On a firm surface (such as asphalt or concrete), the exemplary ladder 300 can also be advantageously set up without the exemplary additional element 200.

[0081] Fig. Figure 5b shows the exemplary additional element 200 attached to the exemplary traverse 310 (or cross traverse 310) according to Fig. 5a in side view.

[0082] Reference should be made to the explanations regarding Fig.5a referred to and here merely shown once again the adaptation of the exemplary additional element 200 to the cross-section of the traverse 310 of the conductor 300 chosen here as an example, which is advantageously possible by the already described rotation of the clamping section 230 relative to the projection 220 due to the cylindrical cross-section / cylindrical shape of the basic element 211 of the main section 210.

[0083] Furthermore, the shape of the clamping section 230, in particular the provision of the second subsection 212 of the clamping section 230 as a support against the main section 210, allows the full force of the locking section 240, which acts on the clamping element 230, to be used for clamping the exemplary crossbeam 310 of the conductor 300, in order to enable a safe and reliable clamping and thus fastening of the exemplary additional element 200 to the exemplary conductor.

[0084] It should be noted that only examples and embodiments of the present disclosure, as well as technical advantages, have been described in detail above with reference to the accompanying figures. However, the present disclosure is in no way limited or restricted to the embodiments and their features or combinations described above, but also includes modifications of these embodiments, in particular those resulting from modifications of the features of the described examples or from combinations or partial combinations of one or more of the features of the described examples within the scope of protection of the independent claims.
