Description

The present invention relates to a protective fence post for a shockproof and kink resistant protective fence system for fencing an industrial danger area and for the break-free collection of loads according to the preamble of claim 1, as well as a protective fence system with a plurality of such protective fence posts.

Guard fencing systems are used in the industry to block dangerous areas from unauthorized or unintentional intrusion. For this reason, such protective fence posts or corresponding safety fence systems are subject to high demands with regard to impact strength or buckling strength, which are not comparable to fencing in other fields. For example, it must be ensured that the safety fence system can not be breached under an impact load, either for loads that strike the safety fence system towards the danger area or for loads coming out of the danger area onto the safety fence system incident. In other applications, corresponding loads must be able to be safely collected by the protective fence system in both directions.

Fence posts or protective fence systems, as it relates to the present invention, which can also be referred to as industrial safety fence post or industrial safety fence system, are also used in environments where food or other sensitive substances are processed, so that high hygienic requirements are given. In these environments, regular cleaning of the protective fence posts or protective fencing systems is required to prevent infestation with bacteria, To prevent germs or other small or microorganisms or to remove them sustainably.

As one can easily imagine, bacteria or life nests in the food industry can lead to unpleasant phenomena, which is why the prevention of their occurrence has the highest priority.

Conventional protective fence systems for securing hazardous areas usually have made of square tube or round tube protective fence posts on which fence panels are connected, for example, fence straps. The prior art is on DE 94 07 796 U1 . DE 299 19 902 U1 and DE 298 02 719 U1 directed. An open polygon profile for outdoor fence posts points DE 44 35 967 A1 ,

Further disclosed DE 60 2004 003 180 T2 a profile for a fence post, which is made of a T-shaped profile with bent end portions in order to achieve a particularly high resistance to buckling.

The present invention has for its object to provide a protective fence post and a protective fence system for Fenäunung an industrial hazard area that meets the hygiene requirements described above in particular and excludes the emergence and accumulation of bacterial, germ or life nests with high security. The object of the invention is achieved by a protective fence post with the features of claim 1. The dependent claims describe particularly advantageous embodiments of the invention and a protective fence system according to the invention.

The inventive design, the number of cavities and fillets can be significantly reduced, which is the cleaning and disinfecting considerably relieved. If cavities are provided, they are safely sealed against the environment. One embodiment even provides that the entire protective fence system is free of completely enclosed cavities or hard to reach cavities.

In particular, the hollow profiles in the fence posts according to the prior art contain the danger that bacteria and other vermin settle here. This is especially true when the cavities are drilled for glands. Another weak point are surfaces that are stacked on top of one another and, for example, only partially or not completely tightly welded, between which appropriate nests can form.

According to the embodiment of the invention, therefore, the post body of the protective fence post is formed by an angle with an L-shaped horizontal cross section (that is, a cross section in a horizontal plane), this angle is in particular with its bottom end on a plate and advantageously welded over its entire surface with this is, so again between the front end of the angle and the surface of the plate no cavity is formed.

The protective fence post according to the invention, so that it can be used for fencing an industrial danger area, designed so massive, for example with a post body of angled sheet, especially steel, with a plate thickness between 3 and 8 mm, advantageously between 4 and 5 mm (the limits included ) that he can absorb loads that hit him without breaking and / or deformation. As a rule, such a protective fence post or a protective fence system according to the invention will be designed as an interior post or interior safety fence system, that is to say for use within a closed space, for example an industrial building. be determined. All plates and metals used are advantageously single-layered or single-layered, that is, free of any sandwich type or free of backfoamed, filled or unfilled cavities. As stated below, there may be an exception to the door frame of a door.

On the other hand, at its bottom-distal end, the post body advantageously has bevels which prevent the formation of a flat, horizontal surface from which a liquid, be it cleaning liquid or food liquid, can run off poorly or not. It is therefore particularly advantageous if the post body is bounded at its bottom distal end exclusively by slopes, which slopes extend obliquely with respect to a horizontal plane.

In order to form such bevels, the bottom-distal end faces of the two legs of the angle formed by the post body can form, for example, a tip pointing away in the direction of the ground or from the ground. However, it is alternatively also possible that the angles which form the end faces of the legs with a horizontal plane, are rectified, that is, the slope of the end face of the one leg is continued by the end face of the other leg, with the same slope or one different gradient.

It is favorable if the post body is produced by edges of a flat sheet. The two legs of the angle may have the same length from the connecting line to the free end or different lengths. The included angle can advantageously be 80-100 °, in particular 90 °.

An inventive safety fence system has in addition to a plurality of protective fence posts of the type described at least one fence field, usually a plurality of fence fields, the / with at least one side of a Protective fence posts or are usually connected on both sides to two protective fence posts or be worn between two protective fence posts. Furthermore, at least one door connected to at least one or two protective fence posts is provided.

The two protective fence posts that enclose the door between them, for example, can be supported against each other via a solid profile. Such a solid profile will usually run above the door between the two protective fence posts. The solid profile may for example have a circular or oval cross-section. However, square cross sections, such as rectangular, square or polygonal cross sections are possible. If a rectangular or square cross-section is provided, it is favorable if the solid profile is oriented such that an edge is provided at the lowest point, so that on the one hand a drip edge is formed and on the other hand the overhead surfaces are positioned obliquely with respect to the horizontal plane.

A favorable design of at least one hinge or of several hinges, by means of which the door is connected to a protective fence post, provides that the hinge or each hinge is formed by two hinged plates which are connected to each other via an axis of rotation on the axis of rotation between the plates, a spacer is provided so that a support surface and thus a narrow space between the two plates is avoided. Accordingly, the spacer has a contact surface with respect to both plates or, if it is integral with one of the two plates or connected to the surface, a connecting surface with the plate and a bearing surface with respect to the other plate, which are smaller than an overlap area over which the plates (by far) cover each other. In other words, the bearing surface or connecting surface of the Spacer and each plate smaller than the intersection of the two plates, which arises when the facing surface of both plates are projected vertically in a common plane.

In particular, the height of the spacer, which determines the distance between the two plates to each other, greater than the thickness of each plate, it is advantageously even a multiple thereof.

At a protective fence post next to the door, a position sensor can be connected, which detects a closed state of the door. The position sensor advantageously has a rod-shaped housing with a circular, oval, quadrangular or polygonal cross-section, which is mounted with one of its two end faces over its entire surface on the protective fence posts or which is inserted through the protective fence posts. The other end face is usually assigned to the door or a signal generator provided on the door. Also, the mounted on the door signal generator is advantageously connected over the entire area there or inserted through a retaining plate on the door.

One embodiment provides that the door has a door frame and a fence panel that is at least partially or completely enclosed by the door frame, wherein the door frame is made of a completely dense hollow profile or an open angle profile. The hollow profile may for example have an oval or circular cross-section. However, square cross sections are possible. The open angle profile may, for example, have a T-shaped cross section or an L-shaped cross section or a U-shaped cross section. Other cross-sectional shapes are possible, as well as the use of different interconnected profiles, in particular the said design.

The protective fence post according to the invention and / or other or all components of the protective fence system can be made of stainless steel.

The invention will be described by way of example with reference to exemplary embodiments.

In the FIG. 1 a protective fence post according to the invention is shown with a vertical post body 1 having a bottom end 2 and a distal end 3. Between the two ends 2, 3 is the connection area for the fence panel 4 or for several side by side Fence 4 provided. At the bottom end 2, the post body 1 has a floor anchorage 5, in this case in the form of a plate which is welded over the whole area to the post body 1, for example with a square or else differently shaped base. The plate can be screwed to the floor, for example.

At the bottom end of the post body 1 has a tip 6, which is increased relative to the remaining bottom-remote end faces 7 of the two legs 8 of the post body 1. Namely, said end faces 7 of the two legs 8 form a tip pointing away from the ground or the ground anchoring 5, and thus each have a slope with respect to a horizontal plane. This ensures that liquid from the end faces 7 can drain easily.

Further embodiments of the end faces are exemplary in the Figures 6a and 6b shown. Here, the dashed lines or the hatched plane between two dashed lines serve to illustrate the different heights. According to the FIG. 6a the highest point of the end faces 7 is positioned at the laterally outer end of the first leg 8. The deepest point, however, is positioned at the free lateral end of the second leg 8. Accordingly, there is a slope starting at the lateral end of the first leg 8 down to the connecting line between the two legs 8 and a further slope further down to the free end of the second leg. 8

According to the FIG. 6b is the lowest point of the two end faces 7 positioned on the connecting line of the two legs 8, it is formed, so to speak, a groove. It is favorable if in the groove also a lateral bevel is provided so that no liquid can accumulate here. The two of the groove distal side ends of the legs 8 can be positioned at the same height, as indicated by the hatched plane, or at different heights.

Of course, it is possible to make the bottom end of the post body 1 also different.

In the FIG. 2 a door 9 is shown with a door frame 13 next to a protective fence post. The door 9 will usually be positioned between two protective fence posts. The two protective fence posts or their post body 1 are supported by a solid profile 10 against each other, so as to produce the necessary stability.

The door frame 13 includes a fence panel 4 of the door 9 at least partially or completely. For example, the door frame 13 may be designed as a hollow profile, for example by tight welding together individual rectilinear hollow sections.

In the upper region of the post body 1, a position sensor 11 is connected, which cooperates with a signal generator 12 on the door, here on the door frame 13. Thus, it can be detected whether the door 9 is opened or closed. The connection of the position sensor 11 can also be made in the upper area on the door 9 or in the vertical center or at the bottom of the door or the post body 1.

The position sensor 11 may be placed on the post body 1, for example with an end face of its rod-shaped and generally sealed housing. Alternatively, it is inserted through a hole in the post body 1 and fixed there, for example, screwed. An embodiment provides that the position sensor 11 carries a thread on its outer surface, so that it with this thread either in the Post body 1 can be screwed or two nuts or a projection and a nut on the housing of the position sensor 11, the wall of the post body 1 between them.

In the FIG. 3 an alternative mounting option for the signal generator 12 is shown. Here, this is, as described as an example of the connection of the position sensor 11 described above, inserted through a retaining plate 14 on the door frame 13 and secured there. Alternatively, a placement with an end face on the plate 14 would be considered here or other connection options.

In the FIG. 4 a particularly favorable design of a hinge 15 is shown, by means of which the door 9 can be pivotally connected to the post body 1. The hinge 15 has two hingedly connected plates 16, which are rotatable relative to each other about an axis of rotation 17. The first plate 16 is attached to the post body 1, in particular welded. The second plate 16 is connected to the door 9, in particular on the door frame 13, for example, welded.

How to get in the FIG. 5 can recognize, a spacer 18 is provided on the axis of rotation 17 between the two plates 16. This prevents that a comparatively large surface support between the two plates 16 is formed, which is a space for bacteria nests or the like. The spacer 18 is designed, for example, as a projecting collar on an axis which is inserted through a plate 16 or both plates 16. In the embodiment shown, the collar of the spacer 18 is connected flat on the lower plate 16, for example, welded or integrally formed therewith, and a smaller diameter portion (not shown) extends through the upper plate 16, at its end Thread on which the nut, here in the form of a cap nut 19, is screwed. Other embodiments are possible.

In the FIG. 7 schematically different embodiments for the door frame 13 are shown. Each shows FIGS. 7a to 7d another profile design of an open profile from which the door frame 13 is made. The different profiles can be combined with each other. An angle profile, as described here for the protective fence posts, comes into consideration.

In the FIG. 7 are shown by the dashed lines possible exemplary positions of the protective fence 4, which is partially or completely enclosed by the door frame 13. The thicker lines show the cross section of the door frame thirteenth

According to the Figure 7a For example, the profile of the door frame 13 is made of two parallel sides connected by a roof or an angle.

According to the FIG. 7b the profile of the door frame 13 in the form of a T-profile, wherein the two outer ends of the horizontal bar of the T are bent downwards, in particular obliquely or vertically downwards.

According to the FIG. 7c the profile of the door frame 13 in the form of an upside-down U, wherein the rectilinear roof shown could also be replaced by an arc.

According to the FIG. 7d For example, the profile of the door frame 13 is T-shaped.

In the FIG. 7 shown profiles are particularly suitable for the upper horizontal portion of the door frame 13 and, if a lower horizontal portion is provided, even for this. However, they may also be provided for the lateral vertical sections, but here in particular, even simpler profiles, for example in the form of an angle, can be used.
