Description

The invention relates to a cabinet, in particular safety cabinet, preferably safety underbench cupboard, with at least one articulated to a cabinet body swing door with attached driving lever, and at least one drawer, wherein the swing door and the drawer are interconnected so that the drawer when opening the swing door is pulled out by the driver lever engages in a arranged at an oblique angle relative to a direction of extension of the drawer at this guide profile.

A cabinet of the structure described above, for example, in the WO 92/20259 A1 presented. Here it is about the core, extracts or drawers and an associated swing door automatically operated. However, only solutions with a single swing door are described, thus a cabinet body of limited width.

The GB 725 757 A deals with a cabinet in the interior of a rotatably mounted on a retractable angle support tray is arranged. The angle bracket is coupled via connecting levers with two swing doors.

As part of the DE 849 185 It's about a two-door record container with removable record stand. The record stand rests on its front cross bar on two spreaders. The spreaders are hinged to a door. In addition, the spreaders run in a common center rail of the container bottom.

In addition, a cabinet, in particular safety cabinet example in the utility model DE 20 2004 004 855 U1 addressed. Such cabinets or safety cabinets are usually used for recording dangerous goods such as chemicals or flammable liquids. Accordingly, such safety cabinets usually have automatic closing devices which ensure, for example, in case of fire, that the safety cabinet is reliably closed. Such a self-closing mechanism, which relies primarily on an associated fusible link and a spring arrangement, for example, in the patent DE 103 05 444 B4 the applicant described. Similar goes the DE 20 2004 004 855 U1 in front.

In addition, such safety cabinets are designed by the design of your cabinet body and the doors or the at least one swing door so that a certain fire resistance is guaranteed.

Since the cabinets in question or safety cabinets are filled with dangerous goods, especially chemicals, the insertion and removal of goods to be stored often presents a problem. For example, an operator must first open the revolving door in the class-forming teaching and only then can the interior be Pull out the drawer in order to position a bottle with a chemical, for example. The operation of the swing door and the drawer is often carried out with one hand, whereas the chemical in question or the container is held with the other hand. This is not only cumbersome, but also dangerous in terms of security.

Although the utility model beats DE 20 2006 007 632 At this point, already before a solution in which a cabinet door including a storage unit is mounted as an aggregate in the manner of a carousel around a spaced from the cabinet door and passing through the storage unit rotation axis. In this way, the storage unit with the cabinet door open out of the cabinet body and pivoted into it when the cabinet door is closed. That has proven itself. However, there are no convincing solutions for drawers to date. This is where the invention starts.

The invention is based on the technical problem of further developing such a cabinet, in particular a safety cabinet, in such a way that an expansive structure can be realized in which the handling is simplified and in particular the risk potential is reduced.

To solve this technical problem, the invention proposes in a generic cabinet, especially safety cabinet, that in addition to the first swing door at least another second, connected to the drive lever of the first swing door, and connected to the drawer swing door is provided, both swing doors with dergestalt the drawer are connected, that when opening and closing a swing door, both the drawer and the other swing door also open and closed.

In most cases, the drawer is also inserted again with the help of one of the two hinged doors, but it can also and fundamentally independently experience a closing or insertion movement. Consequently, it is achieved according to the invention that, when a swing door is opened, the drawer automatically undergoes an extract and is pushed in when closing it. This simplifies handling and allows the drawer to be conveniently loaded from and / or laterally.

In detail, the invention proposes for this purpose that the swing door is equipped with the connected driving lever, which engages in the guide profile on the drawer. Usually, the driving lever is connected on the inside to the swing door. This can basically be done in a joint, so that the driving lever relative to the swing door can change its angle.

In general, however, the driving lever includes a fixed predetermined angle with the swing door, so it is connected in an unchangeable position to the swing door. In most cases, the driving lever has an attachment to the inside of the swing door, taking into account a skew angle in the range between about 30 ° and about 80 °, preferably between 40 ° and 70 °. In addition, the driving lever is inwardly connected to the swing door compared to the inside of the swing door.

Moreover, it has proven useful if the driving lever is arranged below a guide plane of the drawer. That is, the drive lever engages from below to the drawer, because it is placed below the management level of the drawer. This guide level of the drawer is defined by at least one guide rail of the drawer, along which the drawer is pulled out and inserted. In most cases, two drawer guide rails are realized, which are defined on the one hand on the inside of the cabinet body and on the other hand are connected to the outside of the drawer and telescope with the drawer and when inserting the drawer with this. Below the guide plane defined by this drawer guide rails of the driving lever is arranged so that in the drawer and insertion of the drawer of the driving lever does not collide with the drawer guide rails.

The guide profile on the drawer for engaging the driving lever is usually designed as a guide rail. In the guide rail engages a guide pin or engage a plurality of guide pins. The one or more guide pins are attached to the driving lever.

The guide profile is arranged at an oblique angle with respect to the extension direction of the drawer at this. Usually, the extension direction of the drawer coincides with the Teleskopierrichtung the drawer guide rail or usually two drawer guide rails. Opposite this telescopic direction or extension direction of the drawer, the guide profile now has an inclined position. In this case, an oblique angle is usually set, which is located in the range between 30 ° and 80 °, preferably between 40 ° and 70 °.

Furthermore, the guide profile or the guide rail is usually connected to the drawer bottom. In this way, the fixed on the swing door entrainment lever, which is located below the management level and therefore below the guide rails and thus also below the drawer bottom, easily interact with the guide rail or the guide rail. For this purpose, the guide pin which projects upwards in relation to the driving lever engages in the guide profile or guide rail arranged above it.

Now, if a swing door is moved, the driving lever slides with its guide pin along the guide profile. The design is generally made so that said guide pin performs a circular arc movement in comparison to a Türachse the swing door. When sweeping the circular arc around the door axis of the guide pin slides along the guide profile, from an initial position to an end position. In this case, the initial position corresponds to the opening of the swing door and consequently simultaneous pulling out of the drawer to the fact that the guide pin is removed from a front side of the drawer. The end position of the guide pin within the guide profile, in contrast, corresponds to a front-facing placement of the guide pin. The means that preferably connected to the drawer bottom guide profile has such an inclined position relative to the extension direction of the drawer, that the initial position of the guide pin within the guide profile of the front of the drawer is farther away than the end position. During the transition of the guide pin from the initial position to the end position in the course of opening the swing door, a force exerted in the axial direction on the drawer by the force exerted by the guide pin simultaneous circular arc movement around the door axis, in such a way that it is automatically pulled out in the process described (and pushed back when closing).

As a result, it is sufficient in the operation of the safety cabinet according to the invention to open one of the two swing doors. Because with this opening process is also the open drawer available and can be filled directly. If now a swing door closed, the drawer follows this closing movement automatically and also goes into its closed position.

It should be emphasized that in the context of the invention, the hinged doors are of course also folding doors or can act. Decisive is the fact that the swing door can be pivoted about the door axis relative to the cabinet body and is articulated in the door axis to this. Moreover, it is of course within the scope of the invention that not only two swing doors can be present in the cabinet body, but also several. Furthermore, of course, several drawers can simultaneously pull out and insert automatically with the help of a swing door. In any case, the handling of the cabinet or safety cabinet according to the invention is increased enormously and accidents are significantly reduced. Especially there is virtually no (more) the risk that, for example, a combustible liquid or another chemical is accidentally dropped when opening the cabinet.

These advantages and effects arise from the fact that both the first swing door and the second swing door are connected together to the drawer. As a result, a drawer can be used, which fills the cabinet body over almost its entire width. The size of the drawer or its width thus corresponds almost to the width of the cabinet body and thus the composite width of the two swing doors.

The design according to the invention is such that the first swing door and the second swing door are connected in such a way with the drawer that when opening and closing a swing door both the drawer and the other swing door also open and closed. So it is sufficient as before, a hand of an operator to automatically open in the cabinet according to the invention both swing doors and the drawer and close. The other hand of the operator is therefore available to handle the hazardous substances available.

That everything succeeds in a relatively large-sized drawer, namely one that fills a cabinet body in its width, which is equipped with two hinged doors (or even more). In this cabinet, in particular safety cabinet, it is an advantageous embodiment of a sub-cabinet, for which the described simple handling is of particular importance.

For such a table under cabinet is usually placed below a laboratory table or a comparable table and is also designed as a safety cabinet, so it represents a safety underbench cabinet. Especially in such a cabinet or safety underbench cupboard, it is important to a simple and safe handling to ensure at the same time large recording volume. This is achieved by the invention described by the possibility described, as it were with one hand by one-handed operation both swing doors open and close as well as pull out the drawer connected thereto and push. The overall succeeds easily and easily, the risk is low, because always a hand of the operator for handling, for example, the chemicals, bottles or containers is still available.

In order to realize the invention described measures in detail, the first swing door is equipped with the already mentioned and connected driving lever. This drive lever engages in the guide profile on the drawer. Mostly the guide profile is found on the underside of the drawer. The guide profile on the drawer is usually designed as a guide rail. In the guide rail, a guide pin or can engage a plurality of guide pin. The guide pin (s) may be attached to the cam lever.

The second swing door is connected to the drive lever of the first swing door. To connect the second swing door with the Mitnehmerhebel the first swing door, the invention proposes a connecting rod or a comparable connecting means. In this case, the connecting rod can preferably engage on the guide pin. This guide pin is located on the driving lever and engages in the guide rail below the drawer.

In this way, both the driving lever and the connecting rod are arranged below the management level of the drawer. D. h., The area of the drawer and starting from the space above a drawer floor are expressly free of any guides, connecting rods, etc., so can be used as a whole for the storage of hazardous substances.

In general, the driving lever is connected at a fixed predetermined angle with the first swing door. In contrast, the connecting rod is pivotally connected both to the second swing door and to the driving lever. Usually, the driving lever is located inside the first swing door. The connection can also be made via a joint, so that the driving lever can change its angle relative to the first swing door. However, this is usually not the case because the driving lever with the first swing door includes a fixed predetermined angle.

In this context, the driving lever has an attachment to the inside of the first swing door, taking into account an oblique angle in the range between about 30 ° and about 80 °, preferably between 40 ° and 70 °. In addition, the catch lever is inwardly connected to the swing door compared to the inside of the relevant swing door.

The guide profile for the guide pin on the catch lever of the first swing door is generally arranged at an oblique angle to a drawer extracting direction of the drawer in question Usually the drawer extract direction coincides with the telescoping direction of a drawer guide rail or usually two drawer guide rails. Opposite this telescoping direction or extension direction of the drawer, the guide profile has an inclined position. In this case, an oblique angle is usually set, which is located in the range between 30 ° and 80 °.

Since the guide profile or the guide rail as well as the connecting rod below the drawer bottom are connected to this, can be a problem Weselwirkung both the driving lever and the connecting rod set up with the guide rail or the guide rail, namely on the common and dipping into the guide rail guide pin , D. h., Which is opposite to the driving lever upstanding guide pin, to which also the connecting rod is connected, engages in the overlying guide profile or the guide rail.

Now, if a swing door is moved, the driving lever slides with its guide pin along the guide profile. At the same time a corresponding force is exerted on the second swing door in this process on the also connected to the guide pin connecting rod. The design is generally made so that the guide pin performs a circular arc movement in comparison to a Türachse the first swing door and the second swing door. When sweeping this (respective) arc, the guide pin slides along the guide profile, from an initial position to an end position. The initial position corresponds to the opening of the two swing doors and Consequently, the simultaneous extension of the drawer to the fact that the guide pin is removed from a front side of the drawer. In contrast, the end position of the guide pin within the guide profile corresponds to a front-side placement of the guide pin.

It should be emphasized that, of course, the hinged door in the context of the invention is also a folding door or can act. The decisive factor is the fact that the respective swing door can be pivoted about the door axis relative to the cabinet body and hinged in the door axis to this. In addition, of course, several superimposed drawers can be automatically pulled out and inserted simultaneously with the help of the two swing doors. In any case, the handling of the cabinet or safety cabinet according to the invention is enormously increased, and at the same time with increased receiving volume of the drawer used. As a result, the accident frequency is significantly reduced. In particular, there is virtually no (more) the risk that, for example, a combustible liquid or even a chemical is accidentally dropped when the cabinet is opened.

According to another advantageous embodiment, the cabinet or safety cabinet according to the invention has a known self-closing mechanism. The self-closing mechanism ensures that in case of fire, for example in case of fire, both swing doors including drawer are closed. Of course, the self-closing mechanism can also be triggered by a contact or the like undergoing an operation. As a rule, however, the self-closing mechanism ensures that the two hinged doors, including the drawer, are closed in the event of elevated temperatures (fire), so that the flammable liquids or hazardous substances inside the cabinet are generally protected from these elevated temperatures.

The self-closing mechanism has a preloaded spring, which acts on a interacting with one of the two swing doors stop when triggered. The spring is advantageously arranged on a rear wall of the cabinet body, on the inside of the cabinet body. In this way, the available installation space is used optimally, especially since the spring is usually in the head region of the cabinet body, so that almost no volume is lost for the dangerous goods to be included

It has proven useful if the stop is designed as a ring stop. Because of this, the stop can advantageously interact with a locking bar, which is connected to one or both of the swing doors. In general, the stopper is moved in a guide. The stop normally assumes a fixed position. This is ensured by a securing unit, which holds the spring of the self-closing mechanism in its biased position. Only in the case of triggering this fuse unit is disconnected and ensures that the stop is released from the fuse unit. As a result, the previously preloaded spring can now relax. In this process, the relaxing spring takes with the stop, which as a result thereof assumes its closed position.

Since the stopper is moved on the one hand in the guide and on the other hand interacts with the closing rod, the rotary door connected to the closing rod experiences a corresponding closing movement. Because one swing door is connected to the drawer and the other swing door, this applies equally to the other swing door and the drawer. In other words, the triggered safety device and the relaxing spring ensure that both swing doors and the drawer are closed together and automatically when triggered. This will any dangerous goods stored in the drawer are optimally protected inside the safety cabinet.

In the following the invention will be explained in more detail with reference to a drawing; the Figures 1-3 . 4A and 4B show a non-inventive embodiment, and thus serve only to explain the mechanical Wirkprincips.

Cabinets are shown in the figures, which in the present case are designed as a safety cabinet and serve for the storage of combustible liquids and gases. The safety cabinet according to the invention has at least two hinged doors 2, 2 'hinged to a cabinet body 1. Furthermore, at least one drawer 3 can be seen.

In order to facilitate the handling and filling and removal of stored in the safety cabinet goods, the swing door 2 is inventively connected to the drawer 3. This is done in such a way that the drawer 3 is automatically pulled out when opening the swing door 2 with and is automatically inserted when closing. In fact, the swing door 2 is connected to a door axis 4 pivotally connected to the cabinet body 1. In the described opening movement, as in the Fig. 1 and 2 4a and 4b, the connection according to the invention between the swing door 2 and the drawer 3 now causes the drawer 3 to be pulled out automatically when the swing door 2 is opened and is automatically pushed in when the swing door 2 is closed.

The invention achieves this in detail by means of the interplay between a driver lever 5 and a guide profile or guide rail 6. The driver lever 5 is connected to the swing door 2, specifically on the inside in the context of the example, that is, on an inside or inside surface of the swing door 2. The driving lever 5 engages in the guide profile 6, which in turn is connected to the drawer 3. In fact, the guide profile or the guide rail 6 is located on a drawer bottom 3a of the drawer 3. For engaging in the guide profile or, the Guide rail 6, the driving lever 5 is equipped with a guide pin 7. The guide pin 7 projects in front of the driving lever 5, in the direction of the drawer bottom 3a. This is explained by the fact that the driving lever 5 is arranged below a guide plane F of the drawer 3.

The guide level F of the drawer 3 is spanned by two drawer guide rails 8, which are mounted on the one hand in the interior of the cabinet body 1 and on the other hand on side surfaces 3b of the drawer 3. As usual, the drawer guide Schlenen 8 telescope when extracting and inserting the drawer 3. Below the plane spanned by this telescoping movement of the guide rails 8 level, the guide level F, is - as I said - the driving lever 5 is arranged. Between the two guide rails 8 there is the guide profile or the guide rail 6. In this way, the upstanding by the follower lever 5 guide pin 7 in the guide rail 6 in question easily intervene.

Based on Figures 3 and 4 one recognizes that the guide profile or the guide rail 6 is connected at an oblique angle α with respect to an extension direction Z to the drawer 3 or the drawer bottom 3a. The angle α moves in the embodiment in the range of 30 ° to 80 °. The design is such that an initial position 9 of the guide pin 7 is arranged in the guide rail 6 with the swing door 2 closed away from a front side 3c of the drawer 3. In contrast, corresponds to an end position 10 of the guide pin 7 at the open swing door 2 to a front near-side arrangement of the guide pin 7, so at a comparatively smaller distance of the guide pin 7 of the front side 3c of the drawer 3 (see. Fig. 4a, 4b ).

Characterized in that the driving lever 5 includes a fixed and predetermined angle β with the swing door, which is located in the range between about 30 ° and 80 ° (see. Fig. 1 ), the guide pin 7 moves when opening and closing the swing door 2 on a circular arc 11 relative to the door axis 4, as shown in the Fig. 4a and 4b is indicated. Since the driving lever 5 is struck fixedly to the swing door 2, the movement of the guide pin 7 takes place along only a circular arc 11. When opening the swing door 2 now moves the guide pin 7 from its initial position 9 to the end position 10. In this process and thus its simultaneous approach to the front 3c of the drawer 3 within the guide rail 6, the drawer 3 is acted upon at the same time with an axial force in the extension direction Z. , As a result, the drawer 3 is opened automatically when opening the swing door 2. The reverse process takes place when closing the swing door 2 and consequently the drawer. 3

In the Fig. 3 is still a rod 12 shown as part of a self-closing mechanism. In fact, the rod 12 acts on a preloaded spring which engages the rod 12 upon reaching a certain temperature and melting an associated fusible link and consequently closes the revolving door 2 and at the same time the drawer 3 connected thereto. The self-closing mechanism may in principle work as described in the two references already incorporated by reference DE 103 05 444 B4 or DE 20 2004 004 855 U1 is described.

In the Fig. 5 to 8 an inventive cabinet is shown, which in the present case is designed as a safety cabinet and again serves for the storage of combustible liquids and gases. As already described, the safety cabinet has the cabinet body 1, which in this context Variant a first swing door 2 and a second swing door 2 'are connected. Furthermore, at least one drawer 3 can be seen. The cabinet is an undercounter safety cabinet which may be located below a table top T, which is not expressly shown.

In order to facilitate the handling and filling and removal of stored in the safety cabinet goods, both the first swing door 2 and the second swing door 2 'are connected to the drawer 3 according to the invention together. D. h., The other second swing door 2 'is like the first swing door 2 connected to the drawer 3. In this way, the drawer 3 when opening the respective swing door 2, 2 'automatically pulled out and automatically inserted when closing the relevant swing door 2, 2'. In other words, the first swing door 2 and the second swing door 2 'are connected to the drawer 3 such that when opening and closing one of the two swing doors 2, 2' both the drawer 3 and the other swing door 2 ', 2 also open and getting closed. Both swing doors 2, 2 'are each connected to a door axis 4 pivotally connected to the cabinet body 1.

In detail, the first swing door 2 is equipped with the connected driving lever 5, which engages in the guide profile 6 on the drawer 3. The driving lever 5 is connected on the inside to the first swing door 2, but could just as well also inside the second swing door 2 'are. In any case, the driving lever 5 engages in the guide profile 6, which in turn is connected to the drawer 3. In fact, the guide profile or the guide rail 6 is found on the drawer bottom 3a of the drawer, in particular the Fig. 6 makes it clear.

For engagement in the guide profile or the guide rail 6 of the driving lever 5 is equipped with the guide pin 7. The guide pin 7 projects in front of the driving lever 5, in the direction of the drawer bottom 3a. This is due to the fact that the driving lever 5 is arranged below the guide plane F of the drawer 3. The guide level F of the drawer 3 is clamped by the two drawer guide rails 8, which are mounted on the one hand in the interior of the cabinet body 1 and on the other hand on the side surfaces 3b of the drawer 3.

As usual, the drawer guide rails 8 can be telescoped during the extraction and insertion of the drawer 3. Below the plane defined by the telescoping movement of the guide rails 8 level, the guide plane F, the driving lever 5 is arranged. Furthermore, below this guide plane F is a connecting rod 13, with the aid of which the second swing door 2 'is connected to the driving lever 5 of the first swing door 2. In fact, the said connecting rod 13 advantageously engages the guide pin 7, which in turn is provided on the driving lever 5.

In this way, the drawer 3 is connected on the one hand to the first swing door 2, namely via the driving lever 5, which engages with its guide pin 7 in the guide rail 6 on the drawer bottom 3a of the drawer 3. On the other hand, the drawer 3 or the first swing door 2 is a complementary connection with the second swing door 2 ', namely on the connecting rod 13. Because the connecting rod 13 is coupled to the one guide 7 and thus the drawer 3 and the first swing door 2 and on the other hand connected to the second swing door 2 '.

Based on Fig. 7A . 7B it can be seen that the guide profile or the guide rail 6 is connected at the oblique angle α with respect to the extension direction Z to the drawer 3 or the drawer bottom 3a. The angle α moves in the embodiment in the range of about 30 ° to 80 °. In contrast, the connecting rod 13 is a respective articulated coupling on the one hand with the guide pin 7 and on the other hand with the second swing door 2 'a. Thus, while the driving lever 5 includes the fixed predetermined angle β with the first swing door 2, the connecting rod 13 is pivotally connected both to the second swing door 2 'and the driving lever 5.

Based on Fig. 7A and 7B It is clear that the guide pin 7 when opening and closing the two swing doors 2, 2 'again moves on a circular arc 11 relative to the associated door axis 4 of the first swing door 2. In a comparable manner, the guide pin 7 also describes a circular arc with respect to the door axis 4 of the second swing door 2 ', which, however, is not shown. In any case, the guide pin 7 moves when opening the two swing doors 2, 2 'from its initial position 9 as shown Fig. 7A to the end position 10 after the Fig. 7B ,

In this process, and consequently the simultaneous approach of the guide pin 7 to the front side 3c of the drawer 3 within the guide rail 6, the drawer 3 is acted upon at the same time with an axial force in the extension Z direction Thus, the drawer 3 when opening the two swing doors 2, 2 'automatically with open. The reverse process takes place when closing the two swing doors 2, 2 'and consequently also the drawer 3. By this special design, the drawer 3 can fill the cabinet body 1 over almost its entire width. It Thus, it is possible to use a particularly wide drawer 3 covering as it were two hinged doors 2, 2 '.

The Fig. 5 to 8 Finally, a self-closing mechanism can be detected in the same way. This has in its basic structure, first of all, a biased spring 12a, which acts on a stop 12b. The stop 12b interacts with one or both swing doors 2, 2 ', in the event of triggering. It can be seen that the prestressed spring 12a is arranged on a rear wall of the cabinet body 1, namely on the inside of the cabinet body 1. The stop 12b is an annular stop 12b, a locking bar 12c being guided through its annular opening. The locking bar 12c is pivotally coupled to the second swing door 2 'in the exemplary embodiment and not restrictively. Finally, a guide 12d for the stop 12b and a securing unit 12e also belong to the other elements of the self-closing mechanism.

Normally, in the Fig. 5 to 8 is shown, the stopper 12b is held by the securing unit 12e in a fixed position. Only in the case of triggering, for example in case of fire, the stopper 12b is released from the fuse unit 12e. In this case, the fuse unit 12e undergoes a disconnection because the fuse unit 12e essentially has two fuse elements coupled together by a fusible link, for example metal plates. As soon as a certain temperature is exceeded, the melting solder melts and the two securing elements or metal plates are separated from one another.

As a result, the stop 12b is released from the securing unit 12e and provides the tensioned spring 12a that the stop 12b of the relaxing spring 12a follows. In this process, the stopper 12b moves along the guide 12d as an arrow in FIG Fig. 7B suggests.

Because the stopper 12b is formed as a ring stopper and the lock rod 12c is passed through the stopper ring 12b, the lock rod 12c is also urged. Because the locking bar 12c has a collar on which the ring stop 12b rests in this process. As a result, the second swing door 2 'connected to the lock bar transitions into its closed position. Since the drawer 3 and also the first swing door 2 are coupled to the second swing door 2 'as described, this process also corresponds to the fact that the first swing door 2 and the drawer 3 also assume their closed position.

D. h., When triggered, the described self-closing mechanism ensures that both swing doors 2, 2 'closed and the drawer 3 connected thereto is inserted. Any hazardous goods located on the drawer 3 are thus transferred to the interior of the cabinet body 1, which at the same time undergoes a closure in this process. As a result, the dangerous goods are protected from, for example, fire.
