Description

[0001] The present invention relates to a ladder system comprising a ladder and a ladder cover for such a ladder system.

[0002] Ladder systems with fixed ladders featuring a safety net are known, for example, from DIN EN ISO 14122-4. Fixed ladders with a safety net have stiles, multiple rungs, and a safety net that includes, for example, vertical braces and attached horizontal rings. Such ladders are used, for example, at industrial plants or buildings, particularly commercial and / or industrial buildings, to provide access to a roof. A user of these ladder systems can hold onto the stiles or rungs and place their feet on the rungs when ascending and descending.

[0003] A disadvantage of the known ladder systems is that animals, especially pigeons, for example city pigeons, can enter the movement area of ​​the ladder systems and then contaminate the movement area and / or adjacent areas.

[0004] In many cases, a net or grid is therefore provided on the back guard and / or around the ladder. A disadvantage of these ladder systems is that animals can still enter the ladder's working area. Small animals can also get through the openings in the net or grid. The net and / or grid further hinders the animals from leaving the working area. This leads to increased soiling of the ladder systems and adjacent areas, and in the worst case, to the death of animals in the working area or in adjacent areas.

[0005] The invention is therefore based on the objective of avoiding or at least reducing the disadvantages of the prior art.

[0006] The invention solves the stated problem by providing a ladder system with the features of the main claim and a ladder with the features of the dependent claim. Advantageous embodiments and further developments of the invention are disclosed in the dependent claims, the description, and the figures.

[0007] The ladder system according to the invention, comprising (a) a ladder, in particular a fixed ladder with back protection, with (i) two ladder stiles extending along a ladder direction, (ii) a plurality of ladder rungs spaced apart from one another and extending between the ladder stiles, (iii) at least one brace spaced apart from the ladder stiles and extending at least also in the ladder direction, (iv) at least one ring bracket attached to at least one brace and / or at least one ladder stile, (v) wherein at least one ring bracket, the at least one brace and the ladder rungs define a movement space that has an exit opening, is characterized by (b) a ladder cover for covering the exit opening, wherein the ladder cover (i) has a cover body with a base body and at least one wing movably arranged on the base body,which can be moved into a first position and into a second position, and (ii) has a connecting element which pivotably connects the cover body to the ladder, so that the cover body can be moved from a closed position to an open position when the at least one wing is in the second position.

[0008] The ladder direction is the direction in which the ladder extends. For example, if the ladder is attached to a house wall or another building, such as a chimney, the ladder direction is usually vertical.

[0009] Of course, it is also possible for the ladder to be used at an angle. In this case, the ladder direction is also inclined accordingly. The at least one strut extends at least in part in the direction of the ladder. In a preferred embodiment, the at least one strut is parallel to the ladder stiles, so that it extends exclusively in the direction of the ladder. This is advantageous, but not necessary for the invention. It is quite possible, and advantageous for certain applications, if the at least one strut extends at least partially in a direction other than the direction of the ladder, for example, in a direction perpendicular to it.

[0010] The movement space of a ladder is the space through which a person moves while using the ladder from one end to the other. This movement space can generally be described as essentially cylindrical. It therefore has two end faces, which are referred to as exit openings. Since the ladder can be used in both directions, no distinction is made between entry and exit openings. For example, when the ladder is used to go from bottom to top, the person enters the movement space through the lower exit opening and exits through the upper exit opening. In the reverse direction, the person enters the movement space through the upper exit opening and exits through the lower exit opening.

[0011] The cylindrical movement space preferably has a constant cross-section along its length, which extends from one outlet opening to the other and thus along the conductor direction. This cross-section can be circular or have another contour. Typically, the cross-section is not circular.

[0012] In a preferred embodiment, the movement space is limited on one side by the ladder rungs. The cross-section of the movement space is preferably straight in this area, since the ladder rungs are also generally straight. However, curved ladder rungs are also conceivable, which results in a curved, preferably convex, cross-section of the movement space in this area as well. Preferably, the contour of the cross-section of the movement space in the remaining area is defined by the design of the at least one ring bracket. If this bracket is arc-shaped, the cross-section of the movement space in this area is also arc-shaped, preferably also convex. The ladder stiles are arranged where the two areas meet.

[0013] The lid body has, in particular, a side facing the rungs when the lid body is in the closed position, and a back side facing away from the rungs when the lid body is in the closed position.

[0014] The base body preferably has a top and a bottom. The lid body is in an extended state when the at least one wing is in the first position. The lid body is in a folded state when the at least one wing is in the second position.

[0015] If the ladder is to be used for ascending, the person enters the working area through the lower exit opening. If this opening is covered by the ladder cover, which is in the closed position, the cover must first be moved into the open position. To do this, it is pivoted upwards, i.e., into the working area. If, on the other hand, the ladder is used for descending, the person enters the working area through the upper exit opening. To provide support and safety for the person and to prevent accidents, the upper exit opening is preferably surrounded by a railing. This railing is preferably formed by at least one strut extending beyond the upper exit opening and at least one additional ring bracket attached to the extended section. Preferably, the railing is formed by several correspondingly extended struts and the at least one additional ring bracket attached to them.Above the upper exit opening, there is therefore a space partially enclosed by the railing. In the area where the cross-section of the movement space is limited by the ladder rungs, the cross-section of this space is open.

[0016] The at least one additional ring bracket is preferably identical in design to the at least one ring bracket of the ladder. If the upper exit opening is covered by a ladder cover whose cover body is in the closed position, the cover body must first be moved into the open position. To do this, it is pivoted upwards, i.e., into the area of ​​the railing.

[0017] Preferably, the exit opening covered by the ladder cover is the upper exit opening. This means, in particular, that a user of the ladder system cannot pass through the upper exit opening when the ladder cover is in the closed position.

[0018] The cross-section of the movement area is preferably convex, like the cross-section of the area partially enclosed by the railing. If an exit opening is covered by the ladder cover, the cover preferably follows the contour of the cross-section. Therefore, it is difficult or impossible to pivot the cover body into the open position when at least one wing is in the first position.

[0019] To open the lid, a user of the ladder system first moves at least one wing from the first position to the second position, for example, by folding the wing upwards so that it rests on the top of the lid's base. The user can then pivot the lid from the closed position to the open position, allowing animals to exit the ladder through the opening. The user can then pivot the lid back to the closed position and move the wing back to the first position, thus at least partially, but preferably completely, covering the ladder's exit opening. This makes it more difficult for animals to enter the ladder's operating space.

[0020] Preferably, the at least one wing is arranged laterally on the base body. The at least one wing thus extends at least in one direction from the ladder rungs to the connecting element that pivotably connects the cover body to the ladder. The connecting element is preferably arranged on the base body of the cover body and connects the base body to the ladder. Preferably, a gap extends between the base body and the at least one wing in a direction perpendicular to the direction of the ladder rungs.

[0021] Preferably, the outlet opening is an upper opening of the movement space. Alternatively, the outlet opening is a lower opening of the movement space.

[0022] The connecting element preferably comprises at least one spring and / or at least one cable. Preferably, the connecting element pivotably connects the cover body to the at least one ring bracket and / or the at least one strut. Preferably, a pivot axis of the cover body runs parallel to the majority of ladder rungs. This design ensures that the ladder system is particularly easy for the user to operate, as it minimizes any restriction of the user's freedom of movement when ascending or descending.

[0023] The lid body advantageously has a shape corresponding to the outlet opening when the at least one wing is in the first position. Preferably, the maximum distance between the contour of the outlet opening's cross-section and the contour of the lid body in the closed position is at most 20 mm, more preferably at most 10 mm, more preferably at most 5 mm, and particularly at most 1 mm, when the at least one wing is in the first position. Preferably, the lid body covers at least 50%, more preferably at least 70%, more preferably at least 90%, and particularly completely, of the outlet opening when the at least one wing is in the first position. This design prevents or at least further hinders the unwanted entry of animals into the operating area.

[0024] In a preferred embodiment, the lid body does not project radially beyond an inner contour of the at least one ring bracket when the at least one wing is in the second position. This embodiment facilitates pivoting the lid body when folded.

[0025] Preferably, the lid body does not project beyond the inner contour of the at least one ring bracket when the at least one wing is in the first position. Alternatively, the lid body projects beyond the inner contour of the at least one ring bracket when extended.

[0026] The lid body advantageously has at least one recess corresponding to an outer contour of the at least one strut. This is particularly advantageous if the at least one strut is arranged radially inside the ring bracket. In this way, the lid body is secured laterally, so that it cannot be moved laterally out of the closed position by external forces, or only with considerable difficulty.

[0027] A stop element, projecting into the movement area, is preferably arranged on at least one strut, at least one ring bracket, and / or at least one of the ladder stiles. The cover body preferably rests on the stop element in the closed position. Alternatively or additionally, the cover body rests on one of the ladder rungs, particularly the uppermost rung, in the closed position. The stop element is preferably a safety clamp and / or an element arranged on such a clamp, which is attached to a strut at a suitable height. Alternatively or additionally, the stop element is attached to the at least one strut via a fastening element. If the strut is designed as a hollow profile open on one side, it is advantageous if the fastening element engages in the hollow profile.It is then preferably clamped, screwed, inserted into, and / or wedged into at least one strut.

[0028] Preferably, the ladder cover has at least one locking element for positively securing the cover body in the closed position, which is arranged on the cover body. Preferably, the locking element can be moved into a locked position and an unlocked position. This is achieved, for example, by making the cover body move into a locked position and an unlocked position. This is preferably only possible when the cover body is in the closed position. The locked position and the unlocked position are therefore sub-positions of the closed position. For example, the at least one locking element is a locking bolt, a clamping element, a hook, or a shoulder, in particular a U-shaped shoulder.Preferably, the at least one locking element is arranged on the base body so that the at least one wing can be moved into the second position while the at least one locking element remains in the secured position, thus ensuring that the cover body is held securely in the closed position. The at least one locking element is preferably formed integrally with the base body. Alternatively, it is designed as a separate element. Preferably, the at least one locking element is arranged on the base body by frictional, positive, and / or material-bonded connection. For example, the locking element is welded, screwed, and / or bonded to the base body.

[0029] Preferably, the at least one locking element, in the secured position, engages behind one of the ladder rungs or a strut of an exit platform of the ladder. The exit platform preferably has a grid with several struts, wherein the at least one locking element engages into this grid so that it is secured to a strut.

[0030] The at least one locking element is preferably moved from the secured position to the unsecured position by shifting, extending and / or pivoting the locking element and / or the cover body.

[0031] Preferably, the ladder cover has at least one spring element arranged on the cover body, which biases the locking element towards the secured position. Preferably, the connecting element is the at least one spring element. The locking element can then be moved from the secured position to the unsecured position by applying a force opposite to the bias of the spring element to the locking element and / or the cover body.

[0032] Preferably, the ladder cover has a first handle located on the underside of the base body. Preferably, the ladder cover has a second handle located on the top of the base body. Using the first handle and / or the second handle, a user can pivot the cover body from the closed position to the open position. In some embodiments, it is possible to apply a force to the cover body, opposing the preload of the at least one spring element, using the first handle and / or the second handle, in order to move the locking element from the locked position to the unlocked position.

[0033] Preferably, the base body has at least one recess. Advantageously, the at least one recess is arranged centrally in the base body. Preferably, the at least one recess is at least partially, but preferably completely, spanned by a mesh. Alternatively or additionally, a transparent disc can be embedded in the at least one recess. It has been shown that such a recess effectively prevents users of the ladder system from stepping on the ladder cover. This prevents the ladder cover from being damaged and / or detaching from the ladder, thus also preventing injuries to users of the ladder system who slip, trip, or fall when stepping on the ladder cover, or who are in the movement area while the cover body is pivoting into the closed position. The movement area is particularly visible through the recess.

[0034] Advantageously, at least one wing is pivotably arranged on the base body via a hinge connection. The hinge connection is preferably a pivot joint.

[0035] Preferably, the at least one wing has a top surface that is substantially parallel to the top surface of the base body when the at least one wing is in the first position. Preferably, the at least one wing can be moved from the first position to the second position by pivoting it upwards. Preferably, the top surface of the at least one wing faces the top surface of the base body when the at least one wing is in the second position.

[0036] Preferably, the ladder cover has two wings. Preferably, the pivot axes of the two wings are essentially parallel to each other.

[0037] Preferably, the swivel angle between the first position and the second position of the at least one wing is at least 90°, preferably at least 120°, and in particular at least 150°.

[0038] Preferably, the lid body has a support element arranged on the base body. The support element preferably extends from the base body on the rung side, so that the lid body rests on one of the ladder rungs in the closed position. The support element is preferably attached to the base body by friction, positive locking, and / or material bonding. For example, the support element can be welded, glued, or screwed to the base body. Alternatively, the support element is formed integrally with the base body. In a preferred embodiment, the locking element is the support element.

[0039] Preferably, the ladder rungs are arranged equidistant from each other. Preferably, the ladder stiles run parallel to each other.

[0040] According to a second aspect, the invention solves the problem by means of a ladder cover for covering an exit opening of a ladder, in particular a fixed ladder with back protection, for the ladder system according to the invention.

[0041] Advantageous designs of the ladder cover for covering the outlet opening can be seen in particular in the preceding descriptions of the ladder system according to the invention.

[0042] With the aid of the attached figures, some embodiments of the invention are explained in more detail below.

[0043] They show Fig. 1 - a top view of a ladder cover with two wings in a first position; Fig. 2 - a top view of a ladder cover with two wings in a second position; Fig. 3 - a perspective view of a ladder cover with a second handle; Fig. 4 - a perspective view of a ladder cover with a locking element; Fig. 5 - a side view of a ladder cover with a locking element; Fig. 6 - a perspective view of a ladder system with a ladder; Fig. 7 - a detailed view of a ladder system with a stop element, Fig. 8 - a perspective view of a ladder system with a ladder cover in the folded state, Fig. 9 - a perspective view of a ladder system with a ladder cover in the extended state, Fig. 10 - a perspective view of a ladder system with a ladder cover in the open position, Fig. 11 - an underside view of a ladder cover in a ladder system according to the invention.

[0044] Fig. Figure 1 shows a top view of a ladder cover 2, which has a cover body 4 with a base body 6 and a left wing 8 and a right wing 10. The two wings 8, 10 are movably arranged on the base body 6 so that they can be moved from a first position shown to a second position. Fig. Figure 1 shows the wings 8, 10 in the first position, in which they are extended. The cover body 4 is therefore in an extended state. In the embodiment shown, the wings 8, 10 are each pivotably arranged on the base body 6 via a hinge connection 12. The wings 8, 10 can be moved into the second position by pivoting them about the pivot axis of the hinge connections 12. Fig. 2 is shown. The lid body 4 is then in a folded state.

[0045] The lid body 4 shown has a straight outer contour on its rib side 22. Towards the sides, the lid body 4 is convex when expanded. On the rear side 24, the lid body 4 has a rounded outer contour when expanded.

[0046] The ladder cover 2 shown is in a disassembled state. To attach the ladder cover 2 to a ladder, a connecting element (not shown) is arranged, for example, on the rear side 24 of the cover body 4, by means of which the cover body 4 can be pivotally connected to the ladder. The cover body 4 can be folded by folding the wings 8, 10. In this state, the cover body can then be moved from a closed position upwards to an open position. In the extended state, in which the wings 8, 10 are in the first, in Fig. When the lid body 4 shown in 1 is in the position shown, it cannot be fully pivoted from the closed position to the open position because, due to its laterally curved shape, the lid body can no longer be pivoted further within the pivoting space of the lid body, which is laterally limited by at least one ring bracket and at least one strut, at a certain angle, as the lid body then abuts at least one ring bracket and / or at least one strut.

[0047] In the closed position, the cover body 4 conceals the exit opening of a ladder system. This significantly hinders animals from entering the ladder's operating space. At the same time, the ladder cover 2 is easy, quick, and safe to operate. Therefore, in emergency situations, a rapid escape via a ladder system with such a ladder cover 2 remains possible.

[0048] The lid body has a central recess 14. A net (not shown) can be stretched over the recess 14, or a transparent disc can be inserted into the recess 14. The recess 14 effectively prevents a user of the ladder system according to the invention from standing on the lid body 4. In particular, this prevents the lid body 4 from moving out of the closed position due to the user stepping on it, thus preventing the user from injuring themselves.

[0049] Fig. Figure 2 shows a top view of a ladder cover 2 with a cover body 4 in a folded state. The wings 8, 10 are in the second position. The base body 6 has a central recess 14 through which the movement space can be seen when the ladder cover 2 is used in a ladder system according to the invention.

[0050] Fig. Figure 3 shows a perspective view of a ladder cover 2 with a cover body 4 in an extended state. The flap 8 is in the first position and is connected to the base body 6 via a hinge connection 12. The base body 6 has a central recess 14. A handle 20 is located on the top of the base body 6. The cover body 4 can be easily pivoted from the closed position to the open position and vice versa using the handle 20. Alternatively or additionally, a handle 20 can be located on the underside of the base body 6. Advantageously, the handle 20 is located on the rung side, so that the force required to pivot the cover body 4 from the closed position to the open position is low.

[0051] Fig. Figure 4 shows a perspective view of a ladder cover 2 with a locking element 16. In the embodiment shown, the locking element 16 is designed separately from the base body 6 and is, for example, welded, glued, or screwed to it. However, it is also possible to form the locking element 16 integrally with the base body 6. A reinforcing element 18 is also arranged on the locking element 16 and is attached to the base body 6 and the locking element 16, for example, by welding, gluing, or screwing.

[0052] Fig. Figure 5 shows a side view of the ladder cover 2 of the Fig. 4. In the illustrated embodiment, the locking element is designed as a U-shaped shoulder. However, it is also possible to design the locking element in a different shape, for example as a locking bolt, clamping element, hook, or similar. The locking element 16 secures the cover body 4 in the closed position. For this purpose, the locking element 16 engages, for example, one of the ladder rungs or a strut of an exit platform of the ladder in the secured position. The locking element 16 can be moved from a secured position, in which it prevents the cover body 4 from pivoting towards the open position, to an unsecured position, in which it does not prevent the cover body 4 from pivoting towards the open position.A spring element (not shown), which may also be the aforementioned connecting element (not shown), can pre-tension the locking element towards the secured position. The locking element can then be moved from the secured position to the unsecured position by applying a force opposite to the pre-tension of the spring element to the locking element and / or the cover body.

[0053] Fig. Figure 6 shows a perspective view of a ladder system 100 with a ladder 102. The ladder 102 has two parallel stiles 104. Rungs 106 extend between the stiles 104 and are spaced apart from each other. Struts 108 are arranged at a distance from the stiles 104, and in the illustrated embodiment, a ring bracket 110 is attached to these struts. The struts 108 extend parallel to the stiles 104. The ring bracket 110, the struts 108, and the rungs 106 define a movement space 114 with an exit opening 116. In the illustrated embodiment, the exit opening 116 is an upper opening of the movement space 114. The ladder 102 has an exit platform 112 with a grid of several intersecting grid struts. The exit platform 112 is arranged on the side of the ladder stiles 104 facing away from the exit opening 116.

[0054] Fig. Figure 7 shows a detailed view of a ladder system 100 with a ladder 102. The ladder 102 has an exit platform 112. A stop element 108 is arranged on a ladder stile 104 and projects into the working area. In the closed position, the cover body of the ladder cover (not shown) rests on the stop element 118, which is in the form of a locking clamp. Alternatively or additionally, it is also possible that the cover body of the ladder cover (not shown) rests on a ladder rung, in particular on the uppermost rung, in the closed position.

[0055] Fig. Figure 8 shows a perspective view of a ladder system 100 with a ladder 102 having two stiles 104 and rungs 106 extending between the stiles 104. The stiles 104 extend along one direction of the ladder. Spaced apart from the stiles 104 are braces 108, on which, in the illustrated embodiment, a ring bracket 110 is arranged. The braces also extend along the direction of the ladder. The ring bracket 110, the braces 108, and the rungs 106 define a movement space 114, which has an upper exit opening 116.

[0056] The ladder cover 2 is in the closed position and in this position at least partially covers the upper exit opening, so that a user of the ladder system cannot pass through the upper exit opening.

[0057] The ladder cover 2 has a cover body 4 with a base body 6 and two wings 8, 10 movably arranged on the base body, which are in the second position shown. The cover body 4 is therefore in a folded state. A recess 14 is arranged centrally in the base body 6, which in the example shown is spanned by a mesh.

[0058] At the rear, the base body is pivotably connected to the ladder 102 via several connecting elements 26. In the example shown, the connecting elements 26 are designed as wire elements. In this example, the connecting elements 26 engage in openings in the base body 6. The wire elements can, for example, be movably arranged on the ladder 102 by being guided around the struts 108 and the ladder stiles 104 in a direction transverse to the direction of the ladder.

[0059] Two locking elements 16 are screwed onto the base body 6, which in the position shown engage behind the uppermost ladder rung 106, so that the cover body 4 is secured in the closed position.

[0060] A handle 20 is arranged on the top of the base body 6. Using the handle 20, a user can apply a force towards the ladder rungs 106 on the cover body 4 before descending, so that the locking elements 16 no longer engage behind the uppermost ladder rung 106. The cover body 4 can then be pivoted into the open position.

[0061] Fig. Figure 9 shows the ladder system 100 according to Fig. 8 with a ladder cover 2 with a cover body 4 in the closed position and in the extended position. Accordingly, the wings 8, 10 are in the first position. The cover body 4 almost completely covers the upper outlet opening. The movement space 114 is visible through the recess 14. In order for the cover body 4 to be moved into the open position, the wings 8, 10 must be moved into the first position (see Fig. 8) be brought. Then the lid body 4 can be pivoted into the open position.

[0062] Fig. Figure 10 shows a ladder system 100 with a ladder 102. The ladder 102 has an exit platform 112 with a grid of several intersecting grid struts. The ladder 102 also has two stiles 104 extending along one direction of the ladder. Rungs 106 extend between the stiles 104. Struts 108 are arranged at intervals from the stiles and, in the example shown, also extend along the direction of the ladder. Several ring brackets 110 are arranged on the struts 108. In the example shown, the ring brackets 110 extend in a direction transverse to the direction of the ladder. The ring brackets 110, the struts 108, and the rungs 106 define a movement space 114 with an upper exit opening 116.

[0063] The ladder cover 2 has a cover body 4 with a base body 6 and two side wings 8, 10. The wings 8, 10 are in the second position. The cover body 4 is in the open position and is held in the open position. The upper exit opening 116 of the movement space 114 can be passed through by a user of the ladder system 100.

[0064] Stop elements 118 are arranged on the struts 108. The stop elements 18 project at least partially into the movement space 114. In the closed position, the lid body 4 rests on the stop elements 118.

[0065] Fig.Figure 11 shows a bottom view of a ladder cover 2 in a ladder system 100 according to the invention. The ladder system has a ladder 102 with two ladder stiles 104 extending along one direction of the ladder. Rungs 106 extend between the ladder stiles 104. Struts 108 are arranged at a distance from the ladder stiles 104, and a ring bracket 110 is attached to these struts. In the example shown, the struts 108 also extend along the direction of the ladder.

[0066] A handle 20 is arranged on the underside of the base body 6. A recess 14 is arranged in the center of the base body 6, which in the example shown is spanned by a net.
