Description

Technical area

The invention relates to a bell post according to the preamble of claim 1.

State of the art

Such bell posts are already known and in use. For example, in the DE 20 2014 102 878 U1 a protective post for securing obstacles, goods and traffic routes is disclosed, whereby this protective post consists of a tubular sound body which is fixed to a floor element so that it can move on one side, whereby a clapper is arranged to swing inside the sound body. This clapper strikes against the inner wall of the sound body when the sound body is moved by external influences, for example by a speeding vehicle, from the vertical rest position to any angled position, whereby the freely swinging clapper strikes against the inner wall of the sound body. This is intended to produce a bell or gong sound which is intended to alert the driver of the vehicle to the collision with the bell post and prompt them to take appropriate countermeasures.

In this context, reference is also made to the DE 199 08 859 A1 There, a post-shaped collision protection device with a held end and a free end is disclosed, in which the held end and the free end are coupled to one another via an elastic connection for the oscillatory support of the free end, and a signaling device is provided with a device for automatically detecting a deflection of the free end and a device for emitting a signal in the event of a deflection of the free end.

Further reference is made to the CH 714 712 A2 There, a standpipe of a barrier post for roadways, parking lots, footpaths or access roads is described, wherein in the interior of the standpipe, in its base section, at least one post holding means in the form of at least one shear screw with a predetermined breaking point that can be detachably connected to a fastening foundation is arranged, whereby a locally fixed fastening of the standpipe and a shearing off of the standpipe when a predetermined force or a maximum desired deflection from the fastening foundation is achieved.

Object of the invention

The object of the present invention is to overcome the disadvantages of the prior art. In particular, the object is to improve the above-mentioned protective post in such a way that even with only light contact, it emits a desired acoustic signal, which reliably alerts the driver of the vehicle being used and other people in the area at a sufficient volume.

The problem with the above-mentioned and well-known protective post is that the clapper provided, which consists of a round ball and an undefined shaft, does not produce the desired bell or gong sound in the desired volume and duration in many situations. This problem occurs in particular when the protective post is only slightly bent, i.e. only bent by a few degrees or centimeters.

However, it is necessary that the desired bell or gong sound is heard at a sufficient volume and for a sufficient duration at the slightest contact with the protective post so that the driver is reliably warned. It should also be possible to use such a protective post on a mobile basis.

Solution to the task

The features according to claim 1 lead to the solution of the problem.

Advantageous embodiments are described in the subclaims.

A major disadvantage of the protective post according to the state of the art is that a round clapper (ball) used there is suspended from a cord that is far too long. In the event of a collision with the protective post, this means that only a moderately loud and short signal is given due to the long pendulum movement. Furthermore, numerous tests have shown that a round clapper, such as the known ball, contributes to the signal being emitted being less intense and over a shorter period of time than with the new and inventive bell posts described below.

The bell post according to the invention consists of a metal tube which has a metal cover on one end and a metal base on the other. The metal tube has a length of 995 mm and an inner diameter of 94.4 mm and an outer diameter of 101.6 mm. The tube can be cylindrical or a polygonal prism. The cover and base are each welded or attached to the end of the tube.

The lid has a diameter of 101.50 mm and a thickness of 4.0 mm.

The base also has a diameter of 101.50 mm, but is more than twice as thick as the lid at 10.0 mm. A threaded hole is located in the middle of the base, which is the point from which the distance to the edge of the base is the same in all directions.

The bottom is connected to a moving element on the side facing away from the pipe.

The moving element is cylindrical and its diameter corresponds to the diameter of the pipe or the diameter of the base and has a thickness of several centimeters, preferably 5 to 10 centimeters.

The movement element is made of rubber or another elastic and springy plastic and is connected to a base plate opposite the side that is connected to the ground. This is a predetermined breaking point so that the pipe and the vehicles driving against it are not damaged.

It can happen that after a vehicle has collided with the bell post several times, the moving element shows signs of wear. For this reason, the moving element can be exchanged or replaced in just a few simple steps. First, the connection between the base plate and the moving element, which was made via the hole, is loosened. Then the connection between the floor and the moving element can be loosened. Then a new moving element can be inserted in the opposite order and connected to the floor and the base plate. This increases the longevity of the bell post according to the invention.

The base plate is square, made of metal and preferably has an edge length of 200 mm and a thickness of 10 mm. The base plate also has a hole in the middle of the base plate. This hole has a first diameter of 32.5 mm, which narrows to a second diameter of 16.5 mm in the direction of the movement element through a 90-degree countersink. The base plate also has four fastening holes, one of which is located in each corner area of the base plate.

The cover of the tube has a welding point on the side facing the tube at its center, which is the point that is the same distance from a cover edge in all directions. At this welding point, a first chain link is joined, in particular welded, to the center of the cover.

At this welding point, a metal chain consisting of three chain links, the first chain link, a second chain link and a third chain link, is arranged over the first chain link. The rotational mobility of the three chain links contributes to the length of the signal tone being extended compared to the state of the art, even in the event of a minor collision with the bell post.

The three chain links are identical to each other in a long-link form and each have a link size of 5 mm by 35 mm, which corresponds to DIN 5685 G 5.0x35.0.

The chain is connected to the third link with a clapper via another weld. This rotational mobility contributes to the length of the signal tone being extended compared to the current state of the art, even in the event of a minor collision with the bell post.

Instead of the welding point, it is also conceivable that eyelets are present. These eyelets can be welded to the same place on the lid and the cover and then also serve to keep the chain links and the clapper freely movable. The eyelet and the additional eyelet can have an inner diameter that is only a few millimeters, preferably 1 to 3 millimeters, over the chain thickness, i.e. 6 mm to 9 mm based on the above-mentioned dimensions of the respective chain links.

The clapper is cylindrical, made of metal and has a diameter of 25 mm and a length of 100 mm. The clapper can also be made of ceramic or another plastic. In these cases, care must be taken to ensure that the weight of the clapper remains largely the same, which can be achieved by making the clapper larger. However, this only makes sense if it does not reduce the excellent sound properties in terms of volume and duration of the signal tone.

The additional welding point is located centrally on one end of the cylindrical clapper. The clapper is therefore connected to the third link of the chain via the additional welding point and hangs inside the tube at a distance from the cover that is precisely determined by the length of the chain.

It can also be provided that the tube has slot-shaped sound openings that pass through the tube. The tube can also be designed as a polygonal prism.

Extensive tests and experiments have shown that the bell post according to the invention with exactly the above-mentioned dimensions, measurements, the above-mentioned chain length and the above-mentioned shape and size of the clapper delivers surprising results.

If the above dimensions and shapes of the individual elements are adhered to, it is guaranteed that the bell post will produce the desired bell or gong sound at an astonishingly high volume and for a surprising duration even with the slightest contact. This is made possible in particular by the exact ratio of chain length, shape and size of the clapper and the diameter of the above dimensions of the pipe. This ensures that the driver of the vehicle that comes into contact with the bell post is warned in an appropriate and, above all, reliably perceptible manner, which also applies to all other people involved. The bell post according to the invention therefore represents a huge improvement on the state of the art.

The moving element is preferably a rubber buffer that has a threaded rod on its surface and a threaded receptacle on its underside, whereby the threaded receptacle can be screwed onto a screw body of the base plate and the threaded rod can be screwed into the bottom of the metal pipe. Such rubber buffers are standard parts from pump technology. They are inexpensive to purchase and easy to store in stock. If a rubber buffer needs to be replaced if it breaks, this can be done easily. The use of such a rubber buffer is part of the protection sought. The screw body can, for example, be welded on or designed to be replaceable using a tool.

To further facilitate the replacement of the rubber buffer, the base has a threaded hole in the center of the base plate to accommodate the screw body. If, for example, the screw body has been damaged in rare cases, the screw body can also be replaced in this embodiment by unscrewing the damaged screw body from the threaded hole and screwing an undamaged screw body through the threaded hole in order to then use the undamaged screw body to screw on the rubber buffer.

In a further embodiment, the base plate forms a movement limiter that is suitable for supporting the metal pipe in an inclined position. The movement limiter is provided on the base plate, for example welded. Its structure forms a stop for the pipe of the bell post. This has the advantage that, for example in narrow passageways or when protecting goods that are standing close to the path of a passing forklift truck, if the bell post is swung around almost to the ground, the goods stored close to the bell post could be damaged by the bell post.

The bell post according to the invention can be firmly connected to a floor with the base plate in the area of a factory gate, in the area of a shelf or the like, wherein preferably screws penetrate the base plate at the fastening holes and engage in the floor.

However, there are also situations that only require temporary protection by the bell post according to the invention, for example when goods to be transported are temporarily parked in an area or a footpath is to be temporarily closed off.

In this case, it is not possible to attach one or more bell posts firmly and permanently to the ground as described above. In this case, mobile bell posts that can be used at short notice are required.

In order to enable a mobile application of the bell post according to the invention, the bell post according to the invention can be equipped with a mobile plate.

This mobile plate is made of metal, is square in shape and preferably has an edge length of 490 mm and a thickness of 10 mm.

This mobile plate has four connecting holes which are arranged in such a way that they are congruent with the fastening holes in the base plate of the bell post. The mobile plate is connected to the base plate using appropriate screws, rivets or the like via the four connecting holes in the mobile plate and the four fastening holes in the base plate.

The mobile plate also has two roller holders spaced apart from each other on one of four outer edges. These roller holders are arranged on the side of the mobile plate which, in the case of seen mounting with the bell post, facing away from a floor and facing the bell post. The two roller holders extend beyond the outer edge of the mobile plate so that the rollers held there protrude with their respective center points beyond the outer edge of the mobile plate.

The rollers only come into contact with the floor to move the bell post if the mobile plate is angled at least 25 degrees to the floor. This means that the rollers come into contact with the floor and the bell post can be easily moved to a designated location and placed there safely.

This has the advantage that it is particularly easy to move the bell post manually using the two rollers, so that the bell post can also be used mobile for short periods of time.

In a secondary claim, a hanging bell post made of a metal tube is disclosed, which has a cover at one end and a base at the other, with a clapper arranged on the side of the cover that faces the tube. The technical components arranged in the hanging bell post correspond exactly to the technical features of the bell post described above.
The metallic tube has a length of 495 mm and an inner diameter of 94 mm to 95 mm and an outer diameter of 101 mm to 102 mm.
The clapper is cylindrical and made of metal and has a diameter of 25 mm and a length of 100 mm, the clapper being connected at one end to a first chain link of a chain via a weld point arranged centrally there, the chain consisting of exactly three metal chain links, namely the first chain link, the second chain link and the third chain link, and the three chain links being of identical long link design and each having a link size of 5 mm by 35 mm, the third chain link being freely connected to the lid at the middle of the lid via a further weld point, the base forming a base loop away from the tube and the lid forming a hanging loop away from the tube.

The hanging loop is used to hang the hanging bell post at a higher location in order to hang the hanging bell post at a defined or preferred height, for example in a factory hall. The floor loop can be used to connect it to the floor of the factory hall. It can also be used to connect or link several hanging bell posts hanging next to each other. A rope, a wire rope or even a rod can be used for this. It is important that the hanging bell posts connected to each other via the floor loop can also react together in this way, as they are operatively connected to each other.

The lid has a diameter of 101.50 mm and a thickness of 4.0 mm and the base has a diameter of 101.50 mm and a thickness of 10.0 mm.

Example

In 1 is a sectional view of the bell post 1 according to the invention and in 2 a view of the bell post 1 according to the invention from a perspective obliquely from above.

The bell post 1 according to the invention consists of a tube 2, which is closed on the one hand by a cover 4 and on the other hand by a base 5, i.e. at the respective end faces.

The base 4 is connected to a base plate 6 via a movement element 12. For this purpose, the base plate 12 has a bore 13 through which a connection to the movement element 12 is established, for example by means of a screw.

The base plate 6 serves to attach the bell post 1 to a floor not shown, for example a hall floor, whereby the fastening holes 14.1, 14.2, 14.3 and 14.4 can be used, which are each arranged in a corner area of the base plate. Optionally, a connection to a mobile plate 15 can also be made via these fastening holes 14.1, 14.2, 14.3 and 14.4. The mobile plate 15 is in the 3 and 4 shown.

The cover 4 of the tube 2 has a further welding point 9.2 on the side facing the tube at its center point M, which is the point that is the same distance from a cover edge in all directions.

A metal chain 8, consisting of three chain links, a first chain link 7.1, a second chain link 7.2 and a third chain link 7.3, is arranged at this further welding point 9.2. The third chain link 7.3 is connected to the cover 4 via the further welding point 9.2.

The three chain links 7.1, 7.2, 7.3 are identical to each other in long-link form and each have a link size of 5 mm by 35 mm, which corresponds to DIN 5685 G 5.0x35.0.

The chain 8 is connected, on the other hand, i.e. with the first chain link 7.1, to a clapper 3 on its front side 10.1 via a weld 9.1.

The clapper 8 is cylindrical or designed as a polygonal prism, is made of metal and has a diameter of 25 mm and a length of 100 mm.

• Das Rohr 2 weist bevorzugt eine Länge von 995 mm und einen Innendurchmesser von 94,4 mm sowie einen Außendurchmesser von 101,6 mm auf. Es kann auch vorgesehen sein, dass das Rohr 2 eine Länge von 980 mm bis 1010 mm und einen Innendurchmesser von 90 mm bis 105 mm sowie einen Außendurchmesser von 970,2 bis 112,2 mm aufweist. Eine Rohrstärke sollte bevorzugt 7,2 mm liegen, kann aber entsprechend der angebenden Bereiche von Innen- und Außendurchmessern variieren.

Since the dimensions of the bell post according to the invention are of central importance, they are listed again below:

• The pipe 2 preferably has a length of 995 mm and an inner diameter of 94.4 mm and an outer diameter of 101.6 mm. It can also be provided that the pipe 2 has a length of 980 mm to 1010 mm and an inner diameter of 90 mm to 105 mm and an outer diameter of 970.2 to 112.2 mm. A pipe thickness should preferably be 7.2 mm, but can vary according to the specified ranges of inner and outer diameters.

The lid 4 preferably has a diameter of 101.50 mm and a thickness of 4.0 mm.

The base 5 also preferably has a diameter of 101.50 mm and a thickness of 10.0 mm.

The diameters of the cover 4 and the base 5 refer to the above-mentioned preferred outer and inner diameters of the pipe 2. It is of course clear that the diameters of the cover 4 and the base 5 are adapted accordingly to the diameters of the pipe 2, should there be any deviation from the preferred dimensions.

The base plate 6 is square and preferably has an edge length of 200 mm and a thickness of 10 mm.

The base plate 6 also has a bore 13 in a base plate center GM. This bore 13 has a first diameter D1 of 32.5 mm, which narrows by a 90 degree countersink to a second diameter D2 of 16.5 mm in the direction of the moving element 12. Here too, changes can of course be made to the diameter of the bore 13, as long as this does not impair or restrict the connection to the moving element 12.

The movement element 12 is cylindrical and corresponds in diameter to the diameter of the pipe 2 or the diameter of the base 5 and has a thickness of several centimeters, preferably 5 to 10 centimeters.

In the 3 and 4 a mobile plate 15 according to the invention is shown in a view from below onto a lower side U and in a side view.

The mobile plate 15 is square in shape and has an edge length of the four outer edges 20.1, 20.2, 20.3, 20.4 of preferably 490 mm. The thickness 21 of the mobile plate 15 is preferably 10 mm.

The mobile plate 15 has four connecting holes 19.1, 19.2, 19.3, 19.4, which are arranged such that they are congruent with the fastening holes 14.1, 14.2, 14.3, 14.4 of the base plate 6 of the bell post 1.

The mobile plate 15 is connected to the base plate 6 via the four connecting holes 19.1, 19.2, 19.3, 19.4 of the mobile plate 15 and the four fastening holes 14.1, 14.2, 14.3, 14.4 of the base plate 6 using corresponding screws 18, rivets or the like.

The mobile plate 15 also has two roller holders 17.1 and 17.2 spaced apart from one another on the outer edge 20.1. These roller holders 17.1, 17.2 are arranged on an upper side O of the mobile plate 15, which, when mounted with the bell post 1, face away from a floor (not shown) and the Underside U is opposite. The two roller holders 17.1 and 17.2 extend beyond the outer edge 20.1 of the mobile plate 15, so that a roller 16.1, 16.2 received in a roller holder 17.1 and 17.2 protrudes with its respective center point 22 beyond the outer edge 20.1 of the mobile plate 15.

The rollers 16.1, 16.2 only come into contact with a floor (not shown) for moving the bell post 1 if the latter is angled with the mobile plate 15 via the outer edge 20.1 and the rollers 16.1, 16.2 by at least 25 degrees to the floor (not shown).

Furthermore, the movement element 12 shown here is a rubber buffer which has a threaded rod 24 on its surface and a threaded receptacle 25 on its underside, wherein the threaded receptacle 25 can be screwed onto a screw body 26 of the base plate 6 and the threaded rod 24 can be screwed into the base 5 of the metal tube 2. Above and below are designations that refer to the installed state of the bell post when it is properly positioned on a surface.

To make the screw body easier to replace, in the embodiment shown the base 5 has a threaded hole 11 in its base plate center GM for receiving the screw body 26. If, for example, the screw body 26 has to be replaced, it can be unscrewed through the threaded hole 11 and another screw body can then be screwed through the threaded hole 11.

The base plate 6 forms in the 3 shown as an example, a movement limiter 27, which is intended to be suitable for supporting the metal tube 2 in an inclined position. In this way, the inclination of the tube 2 of the bell post 1 is limited in the direction in which the movement limiter 27 is arranged on the base plate 6. This can be, for example, an inclined edge plate, as shown in the 3 is shown. However, the movement limiter 27 can also be a limiting tube arranged parallel to the tube 2 in an initial position.

• Fährt ein Fahrzeug gegen den erfindungsgemäßen Klingelpfosten 1, der entweder über die Grundplatte 6 fest mit einem Boden verbunden ist, oder mittels der Mobilplatte 15 an einer vorgesehenen Position platziert wurde, so entsteht ein lauter Signalton, in Form eines Glocken- oder Gong-Tons, dadurch, dass das Rohr 2 durch diese Kollision aus einer orthogonal zu einem Boden angeordneten Ruheposition in eine zu dieser Position angewinkelten Alarmposition bewegt wurde.

Referring to the 1 to 4 The functioning of the bell post 1 according to the invention is explained as follows:

• If a vehicle drives against the bell post 1 according to the invention, which is either firmly connected to a floor via the base plate 6 or has been placed in a predetermined position by means of the mobile plate 15, a loud signal tone is generated in the form of a bell or gong tone, because the tube 2 has been moved by this collision from a rest position arranged orthogonally to a floor into an alarm position angled to this position.

By angled alarm position is meant that the tube 2 is angled towards the ground by the collision with a vehicle. This change in position, which is easily made possible by the moving element 12, results in the clapper 3 hanging on the chain 8 striking an inner wall 23 of the tube 2 and generating numerous loud bell or gong sounds over an astonishingly long period of time.

The interaction of the above-mentioned length of the three-link chain 8, the precisely defined dimensions of the clapper 3 and the specified dimensions of the pipe 2 ensure that the resulting bell or gong sound is produced even in the event of a minor collision that moves the pipe just a few centimeters from the rest position into the alarm position. This generates a bell or gong signal that lasts for several seconds and is sufficiently loud, which immediately and unambiguously warns the driver of the vehicle and prompts them to stop or change direction.

If the driver reverses the vehicle after such a collision, the tube 2 of the bell post 1 according to the invention automatically moves back from the alarm position to the rest position due to the spring force of the moving element 12.

Further in the 5 a hanging bell post 1.1 is shown, which consists of a metallic tube 2.1, which has a cover 4.1 on the front side and a base 5.1 on the other end, with a clapper 3.1 arranged on the side of the cover 4.1 that is directed towards the tube 2.1: The special feature here is also that the metallic tube 2.1 has a length of 495 mm and an inner diameter of 94 mm to 95 mm and an outer diameter of 101 mm to 102 mm, and the clapper 3.1 is cylindrical, consists of metal and has a diameter of 25 mm and a length of 100 mm. Furthermore, the clapper 3.1 is connected to a first chain link 7.4 of a chain 8.1 on a front side 10.2 via a weld point 9.2 arranged centrally there, wherein the chain 8.1 consists of exactly three metallic chain links 7.4, 7.5, 7.6, the first chain link 7.4, the second chain link 7.5 and the third chain link 7.6, and wherein the three chain links 7.4, 7.5, 7.6 are identically long-linked and each have a link size of 5 mm by 35 mm, wherein the third chain link 7.6 via a further welding point 9.3 to the cover 4.1 at the center M of which is freely connected, wherein the base 5.1 forms a base loop 29 away from the tube 2.1 and the cover 4.1 forms a hanging loop 28 away from the tube 2.1.
