Description

Technical area

The invention relates to personal protective equipment with an information display area. The invention further relates to a method for changing a state of an information display area of personal protective equipment.

Background of the invention

To carry out work in places that are difficult to access, such as at great heights, rope access techniques can be used, in which a worker, also known as a height worker, rappels down to the work site. Height workers are typically used when it is either too expensive or too inconvenient to set up a crane or scaffolding to gain access to the work site. For example, height workers clean windows on high-rise buildings or carry out assembly, maintenance and repair work on wind turbines.

As a rule, workers at height are redundantly secured when working and abseil down to work primarily using standardized special equipment. Depending on the local conditions, they then abseil down from the work site to the ground or climb back up on the rope.

Personal protective equipment, such as fall arrest devices, is used to ensure safety. A height safety device is an extendable lanyard that is equipped with an automatic blocking function.

Due to certification and safety requirements, personal protective equipment must comply with a wide range of specifications, for example, in the case of fall arresters, it remains blocked after blocking until it is released. This will prevent further crashes.

Personal protective equipment can also be used in different ways, which can be problematic from the perspective of the user's safety, as illustrated here using the example of the fall arrester: When used vertically, the fall arrester is mounted in such a way that the connecting means of the fall arrester is not stressed over the edge when used . For example, the fall arrester is mounted on a ceiling, with the space directly below where the fall arrester is installed freely accessible.

When used horizontally, the fall arrester is mounted in such a way that the lanyard of the fall arrester is stressed when used over the edge. For example, the fall arrester is attached to a floor so that the space directly below where the fall arrester is installed is not freely accessible. When used horizontally, the connecting means initially extends parallel to the floor until it reaches an edge and then extends essentially vertically downwards from there. In other words, when used horizontally, the connecting means is stressed over the edge. If there is a risk of edge stress on the lanyard when using the fall arrester, the fall arrester must be tested accordingly for this application and approved for this use.

The certification requirements also require that the weight at which the certification and safety tests were carried out be stated on the fall arrester. However, in the case of fall arresters that are certified for both vertical and horizontal use and for which the certification has been carried out with different weights, this leads to the situation that two different weights are specified on the fall arrester, which is confusing for the user of the fall arrester can be. This increases the risk that the user will use the fall arrester in unapproved situations - for example when the weight is too high - which means that the user's safety cannot be guaranteed.

There is therefore a need to improve the safety of the user of personal protective equipment.

Description of the invention

Based on this situation, it is an object of the present invention to provide means to improve the safety of the user of personal protective equipment and in particular to reduce the risk that the personal protective equipment is used in situations that are not certified for it.

The problem is solved by the features of the independent claims. Advantageous refinements are specified in the subclaims.

Accordingly, the task is solved by personal protective equipment with an information display area, the information display area comprising an information carrier for displaying information from a first application and a second application of the personal protective equipment, the information display area in a first of at least two states exclusively displaying information relating to the first application and in a second state only displays information relating to the second application, and the display of the information display area can be changed back and forth several times between the at least two states.

One aspect of the invention is that information regarding the first application, for example the vertical application in fall arresters, and information regarding the second application, for example the horizontal application in fall arresters, are not visible on the personal protective equipment at the same time. Instead, the information display area comprises at least two states and is designed such that the information regarding the first application is only visible to the user at times when the information regarding the second application is not visible and vice versa. This can prevent the user from incorrectly assigning the information regarding the first application and the second application and, for example, loading the height safety device with a weight that is not permitted for the corresponding application.

Another aspect is that the information display area is designed in such a way that it is possible to switch back and forth between the at least two states several times. Depending on the planned use case, the information display area can be set to the state that corresponds to the planned use case before the personal protective equipment is used. If, for example, it is planned to use the height safety device vertically, the information display area can be set to the state in advance of use in which only information relating to the vertical application is visible to the user via the information carrier. If, on the other hand, it is planned to use the height safety device horizontally, the information display area can be put into the state in advance of use in which only information relating to the horizontal application is visible to the user via the information carrier. In particular, it is possible to switch back and forth several times between the at least two states, so that the personal protective equipment is not defined for just one application, but can be used multiple times for different applications - for example vertical application and horizontal application. This means that the user only has to purchase personal protective equipment and that the information display area also ensures increased safety for the user.

Preferably, the information regarding the first application includes information regarding a first application of the personal protective equipment, for example the application in a first geographical area, or the application at a first predetermined external load. Preferably, the information regarding the second application includes information regarding a second application of the personal protective equipment that is different from the first application, for example the application in a second geographical area, or the application with a second predetermined external load.

Further preferably, the information regarding the first application includes information to be attached to the personal protective equipment due to regulatory requirements in relation to the first application. Further preferably, the information regarding the second application includes information relating to the second application to be attached to the personal protective equipment due to regulatory requirements.

More preferably, the information regarding the first application includes information regarding a horizontal application and more preferably information about a maximum weight load for horizontal application. Further preferably, the information regarding the second application includes information regarding a vertical application and preferably information about a maximum weight load for vertical application.
When used vertically, the personal protective equipment is mounted in such a way that a lanyard of the personal protective equipment is not stressed over the edge when used. For example, the fall arrester is mounted on a ceiling, with the space directly below where the fall arrester is installed freely accessible.

When used horizontally, the personal protective equipment is mounted in such a way that the lanyard of the personal protective equipment is stressed when used over the edge. For example, the fall arrester is attached to a floor so that the space directly below where the fall arrester is installed is not freely accessible. The connecting means extends horizontally Use initially parallel to the ground until it reaches an edge and then extends essentially vertically downwards from there.

According to a preferred development of the invention, it is provided that the personal protective equipment is designed as a height safety device, as a belt, as a protective helmet, as a lanyard, as a rappelling or rescue device, as a fall arrester, as a carabiner, as a rescue device, as a power ascender and/or as a load securing system . Depending on the design of the personal protective equipment, the first and second application also differs.

The fall arrester is preferably a fall arrester that complies with the EN360:2002 standard. Retractable fall arresters are used as part of personal protective equipment against falls (PPE). They usually serve as a connecting means between the safety harness and an anchor point. If a fall occurs when working at height, a brake is preferably activated by a centrifugal force mechanism that reliably cushions the fall. In other words, the height safety device is preferably a fall arrester with a blocking function. The height safety device is preferably designed in such a way that it catches the user within 2 meters in the event of a fall and the force acting on it is not higher than 6kN. The height safety device allows the user to move freely within a radius of action while working at height, and in the event of a fall, the forces acting on the body are reduced by braking and damping systems. The height safety device also preferably enables the lanyard to be adjusted in such a way that the fall distance is kept short even when changing working positions in the event of a fall.

The fall arrester is preferably certified as a first application for horizontal use and as a second application for vertical use. The height safety device is preferably designed in such a way that a maximum user weight for vertical use is 140 kg and that a maximum user weight for horizontal use is 100 kg. Furthermore, the height safety device is preferably equipped in such a way that it is approved for horizontal use even without an additional shock absorber.

The height safety device preferably comprises a connecting means, which can be designed as a rope, steel cable, band and/or webbing. Further preferably, the height safety device comprises a housing, a carabiner, a deflection pulley, a cable pull, an inlet damper, a cable brake and/or a stop device. The connecting means is preferably protected during retraction by the deflection roller integrated in the housing of the height safety device. This protects both the housing of the fall arrester and the lanyard itself from wear. In addition, the energy-absorbing inlet damper prevents the carabiner from hitting the housing unbrakedly when the rope is pulled in. The housing of the height safety device is further preferably UV-impermeable, made of plastic and/or aluminum. In order to ensure the robustness of the fall arrester, the connecting means of the fall arrester is preferably protected from UV radiation by the housing. Plastic and/or aluminum materials also have the advantage that the housing is light and robust.

More preferably, the height safety device can include one or more fall indicators and/or fall indicators. The fall indicator and/or fall indicator - for example a color symbol - preferably indicates whether the fall arrest device is still functional or needs to be checked, for example because a fall has previously occurred. The fall indicator and/or fall indicator can be arranged on a carabiner or on the housing of the fall arrest device. For example, the condition of a brake on the fall arrester can be assessed in this way without opening the housing of the fall arrester.

As already mentioned, one aspect is that the information display area includes the information carrier and is designed in such a way that it is possible to switch back and forth between the at least two states several times. In this context, according to a preferred development of the invention, it is provided that the information carrier is a non-electronic information carrier, and/or that the information carrier is designed as a non-electronic display and/or that the display of the information display area is designed such that between the can be changed between two states without the supply of electrical energy. In other words it is personal Protective equipment is therefore preferably designed in such a way that the state does not change by supplying electrical energy. Instead, the personal protective equipment is preferably designed in such a way that the state can be changed by supplying mechanical energy. This means that the information carrier is long-lasting and does not rely on an electrical energy storage device. The personal protective equipment is therefore preferably free of an electrical energy storage device. Further preferably, the information carrier is designed to permanently display the information regarding the first application and/or the information regarding the second application. The information is particularly preferably applied to the information carrier using printing processes, engraving processes, embossing processes and/or laser inscription.

According to a further preferred development of the invention, it is provided that the information carrier provides information relating to the first application, preferably the vertical application, on its front side and provides information relating to the second application, preferably the horizontal application, on its back side and/or that between the at least two States can be changed back and forth several times by rotating the information carrier around an axis of rotation that lies in a plane of the information carrier. Providing the information on the front and back of the preferably non-transparent information carrier represents an easily implemented possibility that in the first state of the information display area only information relating to the first application is visible and in the second state only information relating to the second application is visible. The information carrier is particularly preferably designed as a sign. The multiple change between the two states is carried out by rotating the information carrier in such a way that the other side of the information carrier is visible to the user after the rotational movement.

In order to easily enable multiple changes of state by rotation, the information carrier is preferably detachably connected to a housing or a surface of the personal protective equipment in the information display area of the personal protective equipment. For example, the information carrier can be detachably connected to the housing via a mechanical connection or via magnetic interaction or connected to the surface. In this context, according to a further preferred development of the invention, it is provided that the information carrier in the information display area is releasably connected to the housing or the surface of the personal protective equipment by means of a clamp connection, or that the information carrier in the information display area is releasably connected to the housing or the surface by means of a screw connection associated with personal protective equipment.

In the case of the clamp connection, the information carrier is preferably connected to the housing or the surface of the personal protective equipment in a force-fitting and/or positive manner, with it further preferably being provided that the information carrier has clamping lugs which engage in recesses in the housing or the surface. In the case of the screw connection, a screw and a corresponding screw hole in the information carrier and/or a corresponding recess and/or recess for receiving the screw in the housing or the surface preferably ensure the connection of the information carrier to the housing or the surface.

As an alternative to the detachable connection of the information carrier to the housing or the surface, it can be provided that the information carrier in the information display area of the personal protective equipment is non-detachably but movably connected to the housing or the surface of the personal protective equipment - for example via a joint and preferably via a swivel joint. In this context, according to a preferred development of the invention, it is provided that the information carrier in the information display area is connected to the housing or the surface of the personal protective equipment by means of a hinge connection.

Particularly preferably, it is provided that the information carrier is designed as a sign that is detachably connected to the housing in the information display area by means of a clamp connection. By loosening the clamp connection, the sign can be removed from the housing and clamped upside down again on the housing, which makes it possible to easily change the state of the information display area.

According to a further preferred development of the invention, it is also provided that the information carrier has a mirror-symmetrical shape, that the information carrier includes clamping lugs for clamping the information carrier to the housing or the surface of the personal protective equipment and/or that the information carrier includes a recess for receiving a screw connection . The mirror-symmetrical shape of the information carrier in relation to a mirror plane perpendicular to the plane of the information carrier enables the information carrier to be easily connected to the housing or the surface of the personal protective equipment even when rotated.

In relation to the clamping connection, the clamping lugs are particularly preferably arranged in mirror symmetry. It is further preferably provided that the housing or the surface of the personal protective equipment in the information display area includes recesses for the clamping lugs of the information carrier, i.e. preferably recesses corresponding to the clamping lugs.

As an alternative to designing the information carrier in such a way that the information carrier provides information regarding the first application on its front side and provides information regarding the second application on its back side, according to a preferred development of the invention it is provided that the information carrier provides information regarding the first application on its front side , preferably provides information regarding the vertical application and information regarding the second application, preferably provides information regarding the horizontal application and the personal protective equipment in the information display area comprises a cover for the information carrier that has a viewing window. In this way, the cover and the viewing window can make it possible in a simple way that in the first state of the information display area only information relating to the first application is visible through the viewing window and in the second state only information relating to the second application is visible through the viewing window. The other information is covered by the cover and is therefore not visible at the same time. The cover is preferably connected to the housing or surface of the personal protective equipment. The information carrier is preferred arranged between the housing and the cover having the viewing window. The cover can also include more than one viewing window.

With regard to the change of state, according to a further preferred development of the invention, it is provided that between the at least two states by a rotational movement of the information carrier about an axis of rotation that is perpendicular to a plane of the information carrier, or by an axial movement of the information carrier along an axis, which lies in a plane of the information carrier, can be changed back and forth several times and / or that can be changed between the at least two states by a rotary movement or axial movement of the cover having the viewing window. In this alternative, a multiple change of state can preferably take place by a rotary movement or by axially displacing the information carrier relative to the cover.

In order to make it easy to change the state, the information carrier in the information display area of the personal protective equipment is preferably connected to the housing or the surface in such a way that the information carrier can be moved relative to the cover. The state of the information display area can thus be changed in a simple manner by moving the cover relative to the information carrier. According to a preferred development of the invention, it is also provided that the information carrier is mounted in the information display area in an axially displaceable or rotatable manner relative to the viewing window of the cover. In other words, the change can take place via a rotary movement or alternatively via a translation.

In relation to the rotational movement, it is particularly preferably provided that the information carrier is designed as a disk which is rotatably mounted relative to the viewing window. Further preferably, the information carrier is rotatably mounted on the housing or the surface via a screw connection in such a way that the information carrier is partially covered by the cover having the viewing window. The information carrier designed as a disk can thus be rotated simply by turning the screw. In this context, according to a preferred development of the invention, it is also provided that the viewing window (or the multiple viewing windows of the cover) and the Information carriers are designed in such a way that either the information regarding the first application or the information regarding the second application is visible through the viewing window or the multiple viewing windows. In other words, the size and shape of the viewing window correspond to the size and shape of the information displayed on the information carrier. It is further preferred that the housing has a recess and/or recess for receiving the screw connection.

As an alternative to the possibility of moving the information carrier to change the state, it can also be provided that the cover having the viewing window is moved. For example, when changing, the viewing window can remain unchanged in relation to the cover and move with the cover - i.e. rotate or shift axially. A different area of the information carrier partially covered by the cover is therefore visible through the viewing window. Alternatively, the viewing window can change relative to the cover when changing. For example, a sliding solution can be provided in which part of the cover can be moved along an axis via a guide rail. The viewing window is initially located on one side of the movable part of the cover, which continually decreases in size as the cover is moved until it is no longer present. In addition, on the other side of the cover, a new viewing window created by moving the movable part of the cover increases until it reaches the size of the original viewing window.

Further technical effects and advantages of personal protective equipment emerge for the person skilled in the art from the description of the method for changing a state of the information display area of the personal protective equipment, as well as from the description of the exemplary embodiments and the figures.

If, on the other hand, in the first step the height safety device with the information display area is provided in the second state, and accordingly only information relating to the second application is visible to the user via the information carrier, after carrying out the subsequent step the information display area of the height safety device is in the first state, so that only information relating to the first application is visible to the user via the information carrier. This prevents the user from receiving information about the first application and the second personal application at the same time Protective equipment is visible, ensuring easy and safe use of personal protective equipment.

According to a preferred development of the invention, it is provided that the information carrier provides information regarding the first application on its front side and provides information regarding the second application on its back side, and that the information carrier in the information display area can be detachably connected to the housing or the surface by means of a clamp connection or screw connection the personal protective equipment is connected, and the step of changing the state of the information display area includes rotating the information carrier about an axis of rotation which lies in a plane of the information carrier.

The changing of the state is therefore preferably carried out by rotating the information carrier, which is preferably designed as a sign. If the front of the sign is initially visible to the user, after rotation the back of the sign is visible to the user and vice versa.

Detailed description of the exemplary embodiments

The principle of the invention is explained below with reference to the figures using the example of personal protective equipment designed as a height safety device 10. The personal protective equipment is not limited to fall arresters 10, but can also be designed as a harness, protective helmet, lanyard, abseiling or rescue device, fall arrester, carabiner, rescue device, power ascender and/or load securing system. Based on the following description using the example of the height safety device 10, the expert will understand the analogous application for other types of personal protective equipment.

Figure 1 shows schematically an exemplary embodiment of a height safety device 10 for vertical and horizontal use. The retractable safety device 10 is designed as a fall arrester and, in this preferred exemplary embodiment, includes a connecting means 12 designed as a steel cable 12 and a carabiner 14 attached to it. In addition, the retractable safety device 10 has a deflection roller integrated in a housing 16 and a cable pull (neither of which can be seen in the figures ). In addition, an energy-absorbing inlet damper 18 prevents the carabiner 14 from hitting the housing 16 without braking when the connecting means 12 is retracted.

As in Figure 1 shown, the height safety device 10 also includes an information display area 20, which includes an information carrier 22 for displaying information. The information display area 20 is designed in such a way that in one first of at least two states exclusively information relating to the first application - in this case the vertical application is visible (in Figure 1 the first state is not shown) and in the second state only information relating to the second application - in this case the horizontal application is visible (as in Figure 1 shown). The information display area 20 is designed in such a way that it is possible to switch back and forth between the two states several times.

In the present exemplary embodiment Figure 1 The height safety device 10 comprises two information display areas 20, each with an information carrier 22 designed as a sign 24, the information carriers each still being in Figure 2 are shown. The signs 24 provide 26 information regarding the vertical application on the front and 28 provide information regarding the horizontal application on the back, in particular the maximum permissible weight with which the height safety device can be loaded in the application. It is possible to switch back and forth several times between the two states of the information display area 20 by rotating the information carrier 22 about an axis of rotation 30, which lies in a plane of the information carrier 22.

In the present exemplary embodiment, one of the signs 24 is detachably connected to the housing 16 of the height safety device 10 by means of a screw connection 32. This sign 24 is as in Figure 2 a) can be seen equipped with a screw hole 34. In the present exemplary embodiment, the other shield 24 is releasably connected to the housing 16 of the height safety device 10 by means of a clamp connection 36. This sign shows 24 as in Figure 2 b) Clamping lugs 38 can be seen, which can engage in recesses in the housing 10. The signs 24 also have a mirror-symmetrical shape, with the mirror plane 40 being perpendicular to the plane of the sign 24.

With reference to Figure 3 A method is explained below for changing the state of the information display area 20 of the height safety device 10. Analogous to that in Figure 1 height safety device 10 shown and the in Figure 2b ) shown information carrier 22, the height safety device instructs Figure 3 a housing 16 and an information carrier 22 designed as a shield 24. The information carrier 22 is detachably connected to the housing 16 via a clamp connection 36. In a first step of the method, the height safety device 10 is provided, in which case the information display area 20 is in the second state and thus only provides information relating to the horizontal application.

In a further step, the information carrier 22 is released from the housing 16 of the height safety device 10 using a screwdriver 42 by levering the information carrier 22 out of its clamping with the housing 16 in order to move the first clamping lugs 38a out of the recess. After the second clamping lugs 38b have been moved out of the recess and the information carrier 22 has been rotated by exactly 180 degrees about the axis of rotation 30, the rotated information carrier 22 is fastened again to the housing 16 of the height safety device 10 by clamping. For this purpose, the second clamping lugs 38b of the information carrier 22 are first guided into recesses on the housing 16.
