BRACKET AND SCAFFOLDING COMPRISING A BRACKET OF THIS TYPE

Abstract

A scaffolding bracket anchors a first vertical scaffolding pole of a scaffolding to a building faade. The bracket has at one end a clamp in order to grip the first scaffolding pole. The clamp can be locked in its closed position. A spring element urges the clamp into the closed position of the clamp with a spring force. In order to actuate the clamp, the bracket can have a first sleeve with a slotted guide by means of which the first sleeve can be transferred from the closed position into the open position of the bracket. The slotted guide may be designed in such a way that the bracket can be locked in the closed position. Furthermore, the clamp can have at least one projection for engaging in the first scaffolding pole in order to allow a particularly secure fastening of the bracket to the first scaffolding pole.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0035] FIG. 1 shows a scaffolding 10 comprising a bracket 12. The bracket 12 connects a first vertical scaffolding pole 14 to a building faade (not shown). For this purpose, the bracket 12 has a clamp 16. The clamp 16 has a first gripping jaw 18 and a second gripping jaw 20. A first projection 22 is formed on the first gripping jaw 18. A second projection 24 is formed on the second gripping jaw 20. To fasten the clamp 16 to the first scaffolding pole 14, the first scaffolding pole 14 has a first scaffolding pole aperture 26, here in the form of a scaffolding pole through-aperture, in which the first projection 22 engages. Furthermore, the first scaffolding pole 14 has a second scaffolding pole aperture 28, here in the form of a scaffolding pole through-aperture, in which the second projection 24 engages.

[0036] The first scaffolding pole 14 is connected to a second scaffolding pole 30. The first scaffolding pole 14 has a tapered diameter at the upper end. The second scaffolding pole 30 is partially pushed at the lower end onto the upper tapered end of the first scaffolding pole 14. The second scaffolding pole 30 has a third scaffolding pole aperture 32, here in the form of a scaffolding pole through-aperture, which is also engaged through by the first projection 22. The second scaffolding pole 30 furthermore has a fourth scaffolding pole aperture 34, here in the form of a scaffolding pole through-aperture, which is engaged through by the second projection 24. The bracket 12 thus not only anchors the first scaffolding pole 14 with respect to the building faade (not shown) but at the same time connects the first scaffolding pole 14 to the second scaffolding pole 30. Here, the first projection 22 is formed in mirror-image fashion to the second projection 24 about a center longitudinal plane 36 of the bracket 12. The bracket 12 can thus be mounted on the first scaffolding pole 14 when rotated through 180 degrees with respect to its longitudinal axis 44 (see FIG. 3).

[0037] FIG. 2 shows the bracket 12 in a side view. It can be seen from FIG. 2 that the clamp 16 is partially guided in a first sleeve 38. If the first sleeve 38 is pulled awayin the direction of an arrow 40from the clamp 16, the clamp 16 opens. The opening movement of the clamp 16 can be achieved in particular by means of a mechanical guide (not shown), for example a slotted guide in the sleeve 38, and/or a spring force loading of a spring (not shown). A displacement of the first sleeve 38 counter to the arrow 40 transfers the clamp 16 into its closed position shown in FIG. 1.

[0038] FIG. 3 shows the bracket 12 in a further partial illustration. It can be seen from FIG. 3 that the first sleeve 38 is displaceable relative to a tube 42 along the longitudinal axis 44 of the bracket 12. In an alternative embodiment of the bracket 12, the tube 42 can take the form of a rod. The further pushing of the first sleeve 38 onto the tube 42 occurs against the spring force of a spring element 46.

[0039] In the unactuated state of the bracket 12, the first sleeve 38 is pressed by means of the spring element 46 into the closed position of the bracket 12 as shown in FIG. 3.

[0040] A second sleeve 48 is at least partially pushed onto the tube 42. The second sleeve 48 has a plurality of engagement through-apertures 50, 52, 54. In the tube 42 there is provided at least one through-aperture (not shown) which can be arranged in alignment with in each case one of the engagement through-apertures 50, 52, 54. A bolt (not shown) can be inserted into the engagement through-aperture 50, 52, 54 which is oriented in alignment with the through-aperture (not shown) in order to lock the length of the bracket 12 in correspondence with the unit spacing of the engagement through-apertures 50, 52, 54.

[0041] FIG. 4 shows a view of the bracket 12 in a partially demounted state. It can be gathered from FIG. 4 that an at least L-shaped aperture 56 is formed in the first sleeve 38. The L shape is indicated in FIG. 4 by a dashed line 58. In FIG. 4, the at least L-shaped aperture 56 is T-shaped. A guide projection 60 protrudes into the at least L-shaped aperture 56. The guide projection 60 is arranged or formed on the tube 42. If the guide projection 60 is situated in the first rectilinear portion 62 of the T shape, the clamp 16 can thus be opened and closed. If, by contrast, the guide projection 60 is situated in one of the two upper lateral portions 64, 66 of the T shape, the clamp 16 is locked in its closed position. The upper lateral portions 64, 66 are part of a second rectilinear portion 68 of the T shape. In other words, the T shape is formed by the rectilinear portions 62, 68.

[0042] The two upper lateral portions 64, 66 of the T shape are designed to be mirror-symmetrical to one another with respect to the first rectilinear portion 62. The first sleeve 38 can thus be rotated clockwise or counterclockwise about its longitudinal axis 44 to the same extent in order to lock the clamp 16 in its closed position.

[0043] Taking all the figures of the drawing together, the invention thus relates, in summary, to a bracket 12 in the form of a scaffolding bracket in order to anchor a first vertical scaffolding pole 14 of a scaffolding 10 to a building faade. The bracket 12 has a clamp 16 at one end in order to grip the first scaffolding pole 14. The clamp 16 can preferably be locked in its closed position. With further preference, the bracket 12 has a spring element 46 which urges the clamp 16 into the closed position of the clamp 16 with a spring force. To actuate the clamp 16, the bracket 12 can have a first sleeve 38. The first sleeve 38 can have a slotted guide by means of which the first sleeve 38 can be transferred from the closed position into the open position of the bracket 12. Here, the slotted guide is preferably designed in such a way that the bracket 12 can be locked in the closed position. Furthermore, the clamp 16 can have at least one projection 22, 24 for engaging in the first scaffolding pole 14 in order to allow particularly secure fastening of the bracket 12 to the first scaffolding pole 14.
