Description

Field of the invention

[0001] The present invention relates to a collision protection device for a load rack. State of the art

[0002] Load racks are designed for the storage and management of goods. The load rack consists of a stable rack frame with vertical supports and horizontal supports. Depending on the design, shelves may also be provided or the horizontal supports may be designed as cross supports. The spacing of the vertical supports and thus the width of each compartment are usually selected to allow the storage of one or more items of storage with predetermined maximum dimensions. For example, the maximum dimensions of a Euro pallet are 1,200 mm when stored lengthwise and 800 mm when stored crosswise. In multi-bay storage, several items of storage are stored side by side in one compartment. The height of the individual compartments is selected according to the height of the stored goods and the requirements of the warehouse.The goods themselves can be stored and retrieved on a pallet, on comparable load carriers such as wire mesh boxes, in a container or loose.

[0003] Since load racks naturally have multiple levels or compartments, industrial trucks are used to load and retrieve items from the upper compartments. Storage occurs by positioning the stored goods horizontally, aligning them vertically, and driving them horizontally or diagonally into the load rack. During storage or maneuvering, an impact situation may arise in which the load rack or an object located in the compartment is struck by or collides with the stored goods or the industrial truck. Therefore, the part of the vertical supports closest to the floor is equipped with a circumferential impact protection (ram guard) that absorbs impacts and reduces damage to the frame.

[0004] An important legal or insurance requirement for warehouses and loading racks is fire protection, which specifies fire extinguishing systems for certain loading racks. The most common form of fire extinguishing system is a sprinkler system, which is equipped with numerous sprinklers that act as spray heads and use water as the extinguishing agent. Other fire extinguishing systems include fire extinguishing systems with different types of extinguishing agents, such as an impulse fire extinguishing system, a water spray system, a water mist extinguishing system, a foam extinguishing system, or a powder extinguishing system. These fire extinguishing systems each have an umbrella-shaped spray pattern, which usually corresponds to a rotating surface that emanates from the spray head, widens towards the bottom, and becomes steeper due to gravity.To ensure that the extinguishing agent released by the spray head is not obstructed (no spray obstruction occurs), horizontal and vertical distances or clearances from the spray head are specified, within which no obstacles may protrude. For example, such distances are specified in Chapter 2.5.4.5 of the freely accessible . FM Global Property Loss Prevention Data Sheet: 2-0 Installation Guidelines for Automatic Sprinklers (as of October 2021) proposed.

[0005] The spray heads of the fire extinguishing system are usually mounted on a ceiling or, especially in high load racks, within the compartments. In the latter case, the spray head protrudes into the compartment so that the spray pattern can run below the horizontal supports, thus avoiding obstruction of the spray. However, the spray head is sensitive to impact, and even minor damage to the spray head or other components of the fire extinguishing system running within the compartment can compromise the operational safety, availability, and / or operational clearance of the load rack. Therefore, an unprotected spray head protruding into the compartment poses a significant risk.

[0006] On the other hand, the frame of the load rack is significantly more stable than the spray head, and scratches and minor damage do not always require decommissioning, thus not limiting the operational safety and availability of the rack. Therefore, the fire extinguishing system can, for example, be installed higher than a horizontal support in front of it, although this can obstruct the spraying. Since the spray head itself has a certain height, this also increases the height of the horizontal support and thus the material requirements, even though there is no structural-mechanical reason for this, resulting in avoidable costs. DE 20 2014 007795 U1 discloses a collision protection device for a load rack according to the preamble of claim 1. Object of the invention

[0007] In view of the above, it is an object of the present invention to provide a collision protection device for a load rack which can protect a fire extinguishing system against collision in a cost-effective manner without impairing its function. Summary of the invention

[0008] The task is carried out by a collision protection with the features of the

[0009] Patent claim 1 is solved. Advantageous further developments are set out in the dependent patent claims.

[0010] The collision protection device for a load rack according to the invention has an elongated main body and a fastening section at each end of the main body in its longitudinal direction. The fastening section is adapted to be attached to a frame of the load rack such that an inner surface of the fastening section touches the frame. This allows the collision protection device to be attached to the load rack and, through the inner surface of the fastening section, absorbs any impact load acting on the collision protection device in a collision situation and transmits it across a large area into the frame. This reliably prevents damage to the fire extinguishing system or other objects located in the collision zone. Furthermore, in the event of damage, only the cost-effective collision protection device can be replaced.

[0011] In addition, it is possible to retrofit the collision protection on existing load racks.

[0012] The main body has a thin-walled cross-section with a contact section, a first leg, and a second leg. A thin-walled cross-section is any cross-section in which there is a nearly constant wall thickness and, for example, bends shape the cross-section. The contact section has a predetermined surface that is aligned parallel to the inner surface of the fastening section, and a surface defined as the contact surface that is opposite the predetermined surface. The predetermined surface thus defines an inner side of the contact section or the main body, which faces the load rack. The contact surface is therefore an outer surface on an outer side and, in the event of approach by an industrial truck, for example a forklift, is contacted by the truck in order to absorb the approach load.This provides a suitable, dedicated area that can accommodate the approach load instead of the load rack and fire extinguishing system in order to avoid damage to the load rack.

[0013] In addition, the contact section has a first longitudinal edge and a second longitudinal edge extending between the fastening sections. The first leg is angled at the first longitudinal edge of the contact section, and the second leg is angled at the second longitudinal edge of the contact section. In the assembled state, the first leg is at the top and the second leg is at the bottom. The two legs significantly increase the rigidity and strength of the contact section in the expected approach direction, i.e., normal to the contact surface.

[0014] A first angle between the contact section and the first leg is 90°. A second angle between the contact section and the second leg is less than 90°. The vertical first leg achieves maximum rigidity in the impact direction, as it provides a thin-walled section perpendicular to the load direction as a stiffener. The acute-angled second leg also provides stiffener, which is not vertical but rather provided at an acute angle (<90°) on the inside of the impact protection. This also significantly increases rigidity.

[0015] The first leg and the second leg naturally protrude in the cross-sectional view in a protrusion direction that is perpendicular to the predetermined surface. Due to the perpendicular first angle, the first leg protrudes with its entire length, i.e. a protrusion width in the protrusion direction corresponds to the length of the first leg. However, since the second angle is acute, the second leg does not protrude with its entire length, but by a smaller amount because the length is projected onto the protrusion direction. More precisely, the protrusion width of the second leg corresponds to the length of the second leg multiplied by the cosine of the second angle. Since the second angle is less than 90° and cos(<90°) < 1, the protrusion width of the second leg is reduced compared to an angle of 90°.This reduces the space required by the second leg while maintaining the same width, thus increasing the usable volume of the load rack. Since the first longitudinal edge of the collision protection is closer to the spray head or another starting point of the spray pattern than the second longitudinal edge, the aforementioned reduced space requirement of the second leg also improves the protective effect and prevents obstruction of the spray pattern of the fire extinguishing system without significantly compromising the stiffening effect.

[0016] Preferably, the collision protection is provided with at least one through-hole near the second longitudinal edge. The acute second angle creates a volume between the lower second leg and the contact section that can collect extinguishing agent in the event of a fire. The extinguishing agent can drain from this volume through the through-hole. This protects the collision protection from the negative effects of the extinguishing agent, such as rust formation or corrosive effects. Furthermore, the extinguishing agent is immediately directed to the fire, thereby increasing fire extinguishing efficiency.

[0017] Preferably, the mounting section has a hole for attachment to the load rack. This allows for the use of simple and cost-effective fastening devices, such as screws (frictional fastening) or rivets (positive fastening). A removable fastening device such as a screw connection is particularly advantageous, allowing the collision protection to be easily replaced.

[0018] Preferably, the hole in the mounting section is a slotted hole. This allows the collision protection to be adapted to various installation situations, and identical collision protection parts can be used for different load racks. For example, the slotted hole can be 60 mm long to allow for adjustments within this length range, for example, if the specifications for the installation height of the fire protection system change.

[0019] Preferably, the fastening section comprises a mounting component configured to form a detachable, positive-locking connection with the load rack. An example of a positive-locking mounting component is a dovetail connection, which enables simple assembly without additional components simply by hooking it in. The mounting component can be formed integrally with the collision protection or separately and can replace or supplement the hole described above. If both the hole and the mounting component are provided, an additional connection can be established via the hole, which reinforces the detachable connection by means of the mounting component and / or prevents its accidental release.

[0020] Preferably, the first leg and / or the second leg are not provided along the entire length of the corresponding longitudinal edge of the contact section. Since the length of the respective leg between the surrounding frame parts is limited by this, the aforementioned measure allows for clearance for vertical frame parts of the load rack. This increases assembly flexibility and allows for frame tolerances to be accommodated without having to adjust the collision protection.

[0021] Preferably, the fastening section has an offset edge that runs parallel to and is offset from the nearest longitudinal edge of the contact section. In other words, the fastening section and the contact section are not at the same height on the side of the first longitudinal edge or the second longitudinal edge. This corresponds to a recess near the corresponding longitudinal edge and the fastening section. This recess can provide additional clearance for various mounting situations, for example, when anti-lift devices, frame connections, protective devices, or the like are to be attached to the vertical frame part. This increases mounting flexibility.

[0022] Alternatively or additionally, the fastening section has a flush edge that runs flush with and continues the nearest longitudinal edge of the contact section. In other words, the fastening section and the contact section are at the same height on the side of the first longitudinal edge or the second longitudinal edge. This can simplify manufacturing.

[0023] Preferably, the collision guard is manufactured by cutting and bending a sheet metal part. This manufacturing method is particularly advantageous and cost-effective for the cross-section according to the invention. Cutting can be done, for example, by punching or laser cutting. Punching allows for particularly high volumes to be produced cost-effectively. Laser cutting allows for easy adaptation to different installation situations, as each collision guard can be cut to size. This increases installation flexibility.

[0024] The sheet metal is preferably steel. Steel is a cost-effective and high-strength material that is particularly advantageous for collision protection. A particularly suitable design uses structural steel with a thickness of 1.5 mm to 2.5 mm; this thickness range enables high rigidity and strength while maintaining low costs. Galvanized or painted steel, or stainless steel, can also be used to make the collision protection more robust and protect it from rust and other environmental influences.

[0025] Preferably, the collision protection device has a damping component provided on the contact surface of the contact section. The damping component serves to absorb minor impacts through elastic or plastic deformation of the damping component without deforming the main body of the collision protection device. This provides additional protection. If the damping component is also detachably attached, for example, by screwing, removable adhesive, or a hook-and-loop fastener, the damping component is also replaceable, which further extends the service life of the collision protection device.

[0026] One option is to make the damper component out of foam. Since foams contain a high air content, this type of damper component offers particularly high levels of protection while remaining lightweight.

[0027] Alternatively, the damper component can be a rubber cover. This allows the collision protection to be constructed as a single piece and cost-effectively.

[0028] Alternatively, the damper component can be made of wood. Wood is inexpensive and easily adaptable to the installation situation, and its shock-absorbing properties are excellent.

[0029] The contact section length is preferably between 1000 mm and 4000 mm. This length range is particularly suitable for equipping conventional load racks with a one-piece collision protection between each pair of beams.

[0030] The length of the contact section is preferably between 1700 mm and 2100 mm, especially 1900 mm. Load racks for multi-position storage of two pallets typically have a nominal width of approximately 1900 mm, influenced by manufacturing tolerances and the appropriate clearances between the pallets and between the pallet and the vertical frame section. Therefore, the actual width can deviate by approximately ±200 mm.

[0031] Alternatively, the length of the contact section is between 2400mm and 3000mm, especially 2700mm. Load racks for three pallets typically have a nominal width of approximately 2700mm; the actual width may vary by approximately ±300mm.

[0032] Alternatively, the length of the contact section is between 3200 mm and 4000 mm, especially 3600 mm. Load racks for four pallets typically have a nominal width of approximately 3600 mm; the actual width may vary by approximately ±400 mm.

[0033] The invention further provides a load rack equipped with the collision protection described above, as well as a sprinkler system and / or a fire extinguishing system. The collision protection according to the invention is particularly suitable for a load rack that is a pallet rack, a cantilever rack, a shelving rack, or a wide-span rack.

Fig. 8 is a side view of a load rack equipped with the collision protection device according to the invention and a sprinkler system. Description of the embodiments Load rack

[0035] An example of a collision protection device according to the invention is shown in Fig. 8 , which shows a load rack 4, a sprinkler system 5 as the fire extinguishing system, and an exemplary collision protection device 1 / 1M in a side view. A fastening section described later is hidden.

[0036] The load rack 4 has a frame 40 with vertical beams 42 and horizontal beams 44 extending horizontally between and connecting the vertical beams 42. A shelf 46 is placed on the horizontal beams 44 so that it is supported thereby and can accommodate a stored item; accordingly, the load rack 4 is a shelving rack. Alternatively, pallets may be placed on the horizontal beams 44 instead of the shelf 46 to provide a pallet rack. As a further alternative, the horizontal beams may not connect vertical beams 42 but may project vertically from a central support to provide a cantilever rack. First embodiment

[0037] Fig. 1 bis 4 show a collision protection device 1 according to a first embodiment. The collision protection device 1 is an elongated component that is to be attached to the (not shown) load rack 4. More precisely, in shelving, pallet, and wide-span racks, the collision protection device 1 is mounted such that it connects two vertical supports 42 of the load rack and runs parallel below the horizontal support 44. In cantilever racks, however, the collision protection device 1 connects two horizontal supports on the side from which the stored goods are stored in the rack.

[0038] The collision protection 1 is mounted at a height which causes a lowermost edge of a contact section 20 of the collision protection 1, described later, to be lower than a lowermost edge of a fire extinguishing system provided on the load rack (see Fig. 8 , where the sprinkler system 5 is shown as the fire extinguishing system). The collision protection 1 thus protects the fire extinguishing system from being accidentally hit, for example by a stored item that is being driven into the load rack using a forklift truck.

[0039] The collision protection 1 has an elongated main body 2 and two fastening sections 3 provided at the ends of the main body 2. The main body 2 has a thin-walled cross-section which Fig. 4 is shown and will be described later. In the first embodiment, the collision protection 1 is a bent sheet steel part manufactured by cutting and bending a sheet metal with a thickness of 1.5 mm.

[0040] The fastening sections 3 are provided at both ends of the main body 2 in its longitudinal direction as a continuation of the main body 2, so that their inner surfaces 3A (surfaces facing the load rack) and outer surfaces 3B (surfaces facing away from the load rack) are respectively flush with the inner surfaces and outer surfaces of the main body 2, as shown in Fig. 1 und 3 is easily recognizable. When the collision protection 1 is mounted on the load rack 4, the inner surfaces 3A rest against the parts of the frame 40 intended for mounting (vertical supports 42 or horizontal supports). In the exemplary embodiment, the attachment to the load rack 4 is achieved by means of a screw connection through a hole 30 provided on each attachment section 3, which is designed as an elongated hole. Alternatively or additionally, the attachment can be achieved via a detachable, positive-locking connection such as a dovetail joint.

[0041] The main body 2 has a Fig. 4 shown cross-section. The main body 2 has a contact section 20 which runs parallel to the fastening sections 3 and lies between them ( Fig. 2 and 4 The contact section 20 is the part of the main body 2 that has an inner surface as a predetermined surface 20A facing the load rack 4, and an outer surface as a contact surface 20B facing away from the rack and being approached or contacted first in a starting situation. Thus, the contact surface 20B serves to receive the load, and the starting load is introduced into the frame 40 of the load rack 4 via the contact surface 20B, the main body 2, and the fastening sections 3.

[0042] The main body 2 further has a first leg 22 and a second leg 24, which serve to stiffen the contact section 20 ( Fig. 4 ). The first leg 22 is angled at a first longitudinal edge 20C (upper edge), the second leg 24 is angled at a second longitudinal edge 20D (lower edge). In the first embodiment, the legs 22, 24 are in the view of Fig. 4 the same length. As in Fig. 2 As can be seen, the legs 22, 24 are shorter than the corresponding longitudinal edge 20C, 20D of the contact section 20.

[0043] One in Fig. 4 marked first angle α, which is an angle between the first leg 22 and the contact section 20, is 90°, so that the first leg 22 in the view of Fig. 4 protrudes from the contact section 20 by its entire length. Thus, the entire length of the first leg 22 is available as a stiffener perpendicular to the starting load. Consequently, the first leg 22 improves the stiffness of the contact section 20.

[0044] One in Fig. 4 marked second angle β, which is an angle between the second leg 24 and the contact section 20, is less than 90°, so that the second leg 24 in the view of Fig. 4 does not protrude from the contact portion 20 by its entire length. More precisely, in the first embodiment, the second leg 24 is provided with a second angle β of approximately 50°. As shown in Fig. 4 As can be clearly seen, the protrusion width of the second leg 24 is thus shorter than the protrusion width of the first leg 22. Nevertheless, the second leg 24 has the same length as the first leg 22, so the stiffening effect is greater compared to a case in which the second leg is angled at 90° and has a shorter length corresponding to the protrusion width. Consequently, the second leg 24 improves the rigidity of the contact section 20.

[0045] The second angle β is selected in this case such that the second leg 24 approximately follows the course of the spray pattern. Thus, the second angle β, which is less than 90°, allows greater clearance for the spray pattern. More precisely, the collision protection 1 can either be arranged horizontally closer to the spray head than a comparison collision protection in which the second angle β is 90°, or arranged further down than the comparison collision protection. Even if the second angle β does not follow the course of the spray pattern, this effect can be maintained as long as the second angle β is less than 90°. In this way, the collision protection 1 can avoid obstructing the spray pattern in any case.

[0046] Although the second leg 24 does not obstruct the spray pattern, parts of the extinguishing agent of the sprinkler system 5 can collect in a volume that remains between the second leg 24 and the contact section 20. The reason for this is that the extinguishing agent can, for example, bounce off the goods stored in the load rack 4 and disperse into the volume. To prevent the extinguishing agent from collecting in the volume, at least one through-hole is provided. Due to gravity, the through-hole is most effective when it is provided at the lowest point of the main body 2, so that the extinguishing agent can flow out of the volume. Since the second longitudinal edge 20D is arranged at the bottom and forms the lowest point of the main body 2, the through-hole is provided directly at the second longitudinal edge 20D.In the first embodiment, three through holes 26 are provided, but their number and location can be adapted to suit the circumstances. For example, it may be expedient to provide the through hole(s) not directly on the second longitudinal edge 20D, but rather in the straight part of the second leg 24 to avoid a notch effect on the second longitudinal edge 20D.

[0047] The collision protection 1 of the first embodiment achieves the effects and advantages set out in the summary of the invention. Modification of the first embodiment

[0048] Fig. 5 bis 7 1M show a collision protection device 1M according to a modification of the first embodiment. The modification has the same components as the first embodiment, specifically the main body 2, the two fastening portions 3, the contact portion 20, the legs 22, 24, the angles α, β, and the three through holes 26. Therefore, repeated descriptions of these components will be omitted below, and only the difference will be explained.

[0049] The collision protector 1M of the modification and the collision protector 1 of the first embodiment differ in the arrangement of the fixing portion 3 with respect to the main body 2. Fig. 5 is a view of the modification which is similar to the view of the first embodiment in Fig. 4 As can be seen from the comparison of the figures, in the first embodiment the fastening section 3 projects upwards beyond the main body 2 ( Fig. 4 ), while the attachment section 3 protrudes downwards beyond the main body 2 in the modification ( Fig. 5 ). More specifically, in the collision protection device 1 of the first embodiment, an uppermost edge 3D of the fastening portion 3 lies above the first longitudinal edge 20C (so that the first longitudinal edge 20C lies between the uppermost edge 3D and the second longitudinal edge 20D), while a lowermost edge 3E of the fastening portion 3 in the collision protection device 1M of the modification lies below the second longitudinal edge 20D. In both cases, the first longitudinal edge 20C is arranged at the top and the second longitudinal edge 20D at the bottom, and both the collision protection device 1 and the collision protection device 1M have their respective lowermost edge of the contact portion 20 below the sprinkler system 5 in order to protect it as described above. Further features of the first embodiment and the modification

[0050] In the following, in particular, Fig. 7 further features common to the first embodiment and the modification are described. In Fig. 7 The modified collision protection device 1M is shown as an example. The collision protection device 1M is shown broken to illustrate that its length can be changed without changing the basic structure and the fastening sections 3.

[0051] More specifically, the collision protection 1, 1M can be manufactured in different lengths. The fastening sections 3 are adapted to the conditions of the frame 40 and form end parts of the collision protection 1, 1M. The middle part between the fastening sections 3 corresponds to the main body 2 or the contact section 20. The length of this middle part is Fig. 7 drawn between the fastening sections 3.

[0052] The length of contact section 20 is between 1000 mm and 4000 mm. This length range is particularly suitable for equipping conventional load racking with a one-piece collision protection between each pair of vertical frame members. Load racking for multi-position storage of two pallets typically has a nominal width of approximately 1900 mm, depending on manufacturing tolerances and the appropriate clearances between the pallets and between the pallet and the vertical frame member. This can cause the actual width to deviate by approximately ±200 mm, resulting in a length of contact section 20 of 1900 mm ± 200 mm. Similarly, a contact section 20 length of 2700 mm ± 300 mm is suitable for load racking for three pallets, and a contact section 20 length of 3600 mm ± 400 mm is suitable for load racking for four pallets.Load racks that are not pallet racks, but cantilever racks, shelving units or wide-span racks, also require collision protection in the aforementioned length ranges, so the collision protection 1.1M is also suitable for these applications.

[0053] As in Fig. 7 As can be seen, in the modification, the uppermost edge 3D of the fastening portion 3 is formed as an offset edge 3C which is offset from the first longitudinal edge 20C, wherein the first longitudinal edge 20C is the closest longitudinal edge to the offset edge 3C. As in Fig. 2As can be seen, in the first embodiment, the lowermost edge 3E is similarly formed as the offset edge 3C, and the offset edge 3C is offset from the second longitudinal edge 20D as the closest longitudinal edge. As a result, the fastening portion and the contact portion are not at the same height on the side of the first longitudinal edge 20C (modification) or the second longitudinal edge 20D (first embodiment), thereby forming a recess near the corresponding longitudinal edge 20C, 20D and the fastening portion 3.

[0054] In the collision protection 1, 1M, fillets are also formed between the first longitudinal edge 20C and the offset edge 3D. This enlarges the aforementioned recess or shortens the second longitudinal edge 20C, so that it is not formed over the entire length of the main body 20. If the fillet is not provided and the longitudinal edge is not shortened, each longitudinal edge is defined as the entire (length of the) edge between the fastening sections 3. Further modifications

[0055] The collision protection 1, 1M according to the first embodiment and the modification has the offset edge 3C. However, a flush edge (not shown) can be formed in its place, which runs flush with and continues the nearest longitudinal edge 20C, 20D of the contact section 20. This eliminates the recess, and manufacturing can be simplified.

[0056] The first embodiment and the modification can be combined so that the uppermost edge 3D is located above the first longitudinal edge 20C and the lowermost edge 3E is located below the second longitudinal edge 20D. In other words, the fastening portion 3 can protrude both upwardly and downwardly beyond the main body 2. As a result, the fastening portion is enlarged relative to the contact portion, which ensures greater assembly flexibility and improves load transmission.

[0057] In the first embodiment, the contact surface 20B is flush with the outer surface 3B of the fastening section 3, but the contact surface 20B can also be offset parallel to the outer surface 3B, so that the fastening section 3 and the contact section 20 are offset parallel to each other in the approach direction in order to optimize the space requirement.

[0058] To further improve the protective effect, the collision guard can further include a damper component (not shown) provided on the contact surface 20B of the contact portion 20. The damper component serves to absorb minor impacts through elastic or plastic deformation without deforming the main body 2 of the collision guard. This provides additional protection. If the damper component is also detachably attached, for example by screwing, removable adhesive, or a hook-and-loop fastener, the damper component is also replaceable, which further extends the service life of the collision guard. One option is to make the damper component from foam. Since foams have a high air content, such a damper component enables particularly high protection. Alternatively, the damper component is a rubber covering. This allows the collision guard to be constructed in one piece and cost-effectively.Alternatively, the damper component can be made of wood. Wood is inexpensive and easily adaptable to the installation situation, and its shock-absorbing properties are excellent.

[0059] In the above, a sprinkler system 5 was described as the fire extinguishing system. However, instead of or in addition to the sprinkler system, any other fire extinguishing system can be provided as a fire extinguishing system on the load rack and protected by the collision protection according to the invention. Examples of other fire extinguishing systems are an impulse fire extinguishing system, a water spray extinguishing system, a water mist extinguishing system (high-pressure water mist extinguishing system or low-pressure water mist extinguishing system), a foam extinguishing system, or a powder extinguishing system. Since all of these fire extinguishing systems have a similar spray pattern, the use of the acute-angled second leg is advantageous in order not to impair the spray pattern. Gas extinguishing systems or systems that do not produce a clear spray pattern can also be protected by the collision protection according to the invention with minimal space requirements.In addition, other components that are not part of a fire extinguishing system can also be protected by the collision protection. Examples of other components include pipelines, cabling, and camera, sensor, and monitoring systems. Furthermore, the collision protection according to the invention is also suitable for vertical installation to protect vertically running components.

[0060] In the above, "angled" includes both a one-piece bending as in the first embodiment and a welding or similar attachment at a specific angle.

[0061] The various embodiments and modifications described above can be combined with each other in their respective characteristics as long as no obvious contradictions arise.

[0062] The collision protection according to the invention is used in particular in commercially used load racks, for example in warehouses or logistics halls. List of reference symbols
