Presentation of the invention

The invention has for its object to provide a stand for a fall protection, which solves the known problems of the prior art and is also adapted to support a displaceable along a rod-shaped support member almost captive on a post.

The object is achieved by the subject matter of patent claims 1 and 6. Preferred embodiments of the invention Steher arise from the dependent claims.

The invention is based on the idea to hold by skillful design of the sliding support member this almost captive to the rod-shaped carrier. Accordingly, the stand according to the invention for a fall device, in particular for securing structures, comprises a rod-shaped support having a locking device in the region of a first end with at least one locking element for locking the carrier in a receptacle, and a support member for receiving a securing element, wherein the Retaining element is displaceable along the rod-shaped carrier. In this case, the support member on its side facing the first end of the carrier at least one notch.

By providing a notch, ie, a recessed area, on the slidable support member at its side facing the first end of the support, it is Particularly advantageously possible to prevent that when a support member is in the vicinity of a not in its arresting position locking member, the support member slides over the unlocked locking member away and can be lost. The notch on the retainer element provides sufficient time for a locking element moving back into its locked position to reach the arresting position before the retainer element also slides over the locking element. In this way it can be ensured with the simplest means that the support member is held captive on the rod-shaped support and can be removed only by deliberate release of the carrier.

According to the invention it is provided that the at least one notch is arranged so that at least one locking element can engage in displacement of the support member along the carrier in the notch. By positioning the notch when the holding element is engaged in the region of the arresting element, it is particularly advantageously possible for the arresting element to return to its arresting position, even though parts of the holding element are already arranged at the same height as the arresting element.

Furthermore, the at least one notch has dimensions such that the at least one locking element can fully engage in the notch, that is, although the part of the support member facing the first end of the support partially protrudes further toward the first end of the support than the locking element, it is possible because the notch of the support member is formed in the region of the locking element, that the locking element is already back in its locked position. In this way it is possible to secure the locking element particularly effective against loss or accidental release. In particular, in the case where the support member directly to a locking element unlocking element such. B. a recording, is applied, it is possible to prevent when pulling out of the post that the support member the pressed state of the locking element unlocking element retains and thus accidentally slipping from the uprights.

Furthermore, the at least one locking element is movable between a retracted position and a position protruding perpendicular to the extension direction of the carrier. In this way, it is particularly advantageous possible to provide a post available, in which the locking element on the one hand allows a secure locking of the post in a receptacle and on the other hand allows a secure locking of the support member, so as to prevent loss of the support member.

In this case, the locking device further comprises an elastic element, in particular a spring formed in the interior of the carrier, which acts on the at least one locking element in the direction of the protruding position with a force. In this way, it is ensured that the locking element, after it has been pushed in to release the locking device, returns to its original locking position.

According to a further embodiment of the invention, the at least one support member in at least two orientations in the axial direction can be pushed onto the carrier. This makes it particularly advantageous possible, insofar as the support member z. B. for securing a footboard serves to attach this on the side of the work surface.

Furthermore, the post has at least one further holding element, which is fixedly arranged on the carrier. At this fixed support member, it is particularly advantageous possible elements such. As a railing, to hold.

The invention further provides a fall protection, in particular for securing structures, according to claim 6 ready. The fall protection comprises a post with a rod-shaped support, which has in the region of the first end a locking device with at least one locking element for locking the carrier in a receptacle and a holding element for receiving a securing element, wherein the holding element along the rod-shaped carrier is displaceable. The recording of fall protection also has on its side facing the wearer at least one notch, wherein the at least one locking element (15) between a retracted position and a direction perpendicular to the extension direction of the carrier protruding position is movable. By forming a notch on the receptacle, it is particularly advantageously possible to ensure that upon release of the post from the receptacle, the locking device moves back into its arresting position as early as possible. In this way it can be ensured that the support member is not accidentally released from the carrier. In addition, the support member can be placed in any orientation on the rod-shaped support without affecting the security function.

The at least one notch in the receptacle is arranged so that at least one locking element when pulling out of the carrier from the receptacle can engage in the notch of the recording. In this way, it is particularly advantageous to ensure that the locking element early on when pulling out of the support from the receptacle zurückverfährt back into its arresting position and thus prevents accidental loosening or slipping out of further following support elements particularly advantageous. In this way, it is ensured that the support elements are indeed on the one hand by deliberately releasing the locking device of the carrier are solvable and on the other hand not be solved when pulling the stanchion from the bracket at the same time and may be lost.

Further, the locking device of the fall protection on at least one slot or an exception in the recording, in or can engage the locking member to fix the support of the post in the receptacle.

According to a further particularly preferred embodiment, the receptacle of the locking arrangement of the fall protection two slots or recesses, which are preferably arranged offset by 180 °, on. In this way, it is particularly advantageous possible to fix the post in various ways in the recording.

Detailed description of preferred embodiments of the invention

Hereinafter, a first embodiment of the invention with reference to in particular the Figures 1-3 described.

Show Fig. 1 and Fig. 3 a stanchion 10, in particular a guardrail, for a fall protection 100 as it is used on construction sites in fall-prone areas to avoid personal injury. These areas can be found in particular on balcony balustrades, at the entrances to staircases or elevator shafts and at the top floor in each case under construction.

In this case, the post 10 has a rod-shaped carrier 12, wherein the rod-shaped carrier 12 is preferably formed rectangular or square in its longitudinal extent. At least one fixedly arranged holding element 26 for receiving a railing 28 (see FIG Fig. 5 ) educated.

Further, on the rod-shaped support 12, a support member 18, which is displaceable along the rod-shaped support 12, formed for receiving a securing element 19 as a Fußbrett. In contrast to the upright in the erection fixedly arranged support members 26, the sliding support member 18 in the installation direction down, so as to push a securing element 19 to the floor and thus to hold. It should be noted, however, that the slidable support member 18 can also be plugged in the reverse orientation.

Fig. 2 shows an enlarged view of the lower and the first end of the carrier 12, wherein the support member 18 is supported on the rod-shaped support 12.

The holding element 18 has a notch 20 on its side facing the first end of the carrier. When the support member 18 is located at the first end of the carrier 12, so the notch 20 is located in the region of a locking device 14th

The locking device 14 comprises a locking element 15 for locking the carrier 12 in a receptacle 16 and for securing the support member 18 against accidental slipping. The locking element 15 is movable between a retracted position and a protruding perpendicular to the extension direction of the carrier 12 position and is acted upon by a formed in the interior of the rod-shaped carrier 12 elastic element, in particular a spring, so that it in the direction perpendicular to the extension direction of the Carrier 12 protruding position (locking position) is moved.

By forming the notch 20 in the region of the locking element 15 ensures that the support member 18, in particular when pulling out of the post 10 from the receptacle 16, not unintentionally or accidentally slides from the carrier and thus lost.

As in Fig. 2 shown, the notch 20 of the support member 18 extends on the length of the locking member 15 on the first end of the carrier 12 facing side of the support member 18. In this way, it is possible if the rod-shaped support 12 is fixed in a receptacle 16 (see Description to Fig. 4 ) and the support member abuts directly with its lower side facing the first end of the carrier 12 side of the receptacle 16, that upon withdrawal of the carrier 12 from the receptacle 16, the locking member 15 returns to its locking position before the support member 18, the locking member 15 and pushes also slides from the rod-shaped carrier. If only on the support member 18, a rectangular Einrastschlitz provided approximately in the shape of the locking member 15, so could not reliably ensure that the locking member when quickly pulling out the rod-shaped support from the receptacle 16, as usual in construction site operation has sufficient time to go again in its arresting position, so as to prevent accidental sliding down of the support member 18.

So that the locking element 15 can be operated easily and possibly with the foot, it is sufficiently large and also has in the longitudinal direction of the rod-shaped support 12 each have bevelled sides, which, if the locking member 15 has been engaged over at least a certain way and the uprights 10th is additionally pulled out under train from the recording, ensure that the locking member 15 automatically engages so far that the rod-shaped support 12 can be removed from the receptacle 16.

Fig. 4 shows a receptacle 16 for the post 10, which can be fixed by means of a fixing device 32 at the bottom. The receptacle 16 is adapted to receive the rod-shaped carrier and further comprises a locking arrangement 22, in which the locking device 14 can be locked, with a slot 24 for receiving the locking element 15 in its locking position. It is possible to form the slot 24 of the locking arrangement 22 on two sides of the receptacle 16 offset by 180 °, so that the rod-shaped support 12 can be inserted into the receptacle 16 in different ways.

Fig. 5 shows a post 10 with mounted on the fixed support members 26 railing 28 and with mounted and held by the support member 18 securing member 19. It can be seen that the support member 18 along the longitudinal direction of the carrier 12 is displaceable (see arrow in FIG Fig. 5 ), so that it is possible to support securing elements 19 such as footboards of various widths by means of the support member 18 that they are substantially flush with the ground, so as to prevent objects from unintentionally to the other Roll side of the fuse element 19, and thus could fall down.

Furthermore, in Fig. 5 to recognize that the support member 18 is provided with two offset by 90 ° notches, so that in the case in which no footboard must be supported, the support member 18 can be removed consciously and can be plugged rotated by 90 ° or in the case , in which a footboard 19 must be supported offset by 90 °, the support member 18 can be plugged offset by 90 °.

Further, according to a second embodiment not (only) the support member 18 is provided with a notch 20, but the receptacle 16 on its side facing the wearer. In analogy to the first embodiment described above, the notch 20 of the receptacle 16 is also arranged so that the locking member 15 when pulling the carrier 12 from the receptacle 16 can engage in the notch 20 and the locking member 15 before it is completely pulled out of the receptacle 16 was completely or at least partially in its arresting position and thus prevents unwanted slipping of the support member 18 from the rod-shaped support 12.

Alternatively, it is also possible according to a third embodiment to provide both the support member 18 and the receptacle 16 each with a notch 20. In this way, it is also reliably possible to prevent accidental slipping of the support member 18 of the carrier 12 when pulling the carrier 12 from the receptacle 16.
