Description

DESCRIPTION SAFETY CABINET The invention relates to a safety cabinet, in particular a hazardous materials cabinet, characterized in that connected to a fastener that moves together in a guide, with the corresponding blades the door via a rotation axis located on the edge of a cabinet body. It is connected to the cabinet body so that it can be rotated and is connected to the related winged door from the two winged doors. at least two parts where the door is connected to the fastener with its own hinge assembly. At least closing operation on the leaf door and both leaf doors applying pressure in the direction of the closing positions of the doors during opening of the fastener along the guide during closing operation is that it has a spring unit, in which it is switched from a closed position to a closing position.

Safety cabinets and especially hazardous materials cabinets are characteristically chemicals, flammable liquids etc. for the storage of generally flammable hazardous materials such as is used. In this context, the closing of the said security cabinet It is important that it is securely locked in operation. For this, the spring unit, in automatic closing operation or in the event of a fire, both leaf doors It ensures that it closes safely and automatically. Conversely, it's normal manual and/or motor-driven and non-automatic opening and closure is foreseen. describes a safety cabinet in which the door is each attached to one end of a synchronous arm. has been made. The opposite ends of the synchronous arm are articulated over a fastener. combined as .

The fastener can be pushed into a guide. Thus, the flap doors open synchronously and they close.

A similar security cabinet is envisaged in the document with reference to EP 2 017 420 A1.

Here, too, the two-leaf doors are attached to a movable connector in a guide. is connected. The spring unit should at least keep the doors closed during the closing operation. It ensures the application of pressure in the direction of the closing positions. Here is the spring unit In normal operation, it is functionally separated from the connector and its It exerts pressure on it only during the closing operation. So the bow unit has a safe function during the shutdown operation. case is provided.

Finally, regarding the current state of the art and the application mentioned above EP 2 221 438 A2, which describes a security cabinet with the shape of that the spring unit is in normal operation, that is, that the flap doors (manually) formed Maintaining the stretched position continuously during the opening and closing movement It has a security cabinet. The spring unit can also be used with flap doors only. during the closing operation, for example, a clutch that interacts in the event of a fire. contains the element. In this context, each of the swing doors is two-handed in normal operation. can be connected to its own fastener within the framework of operation. Winged doors so that they can be moved independently of each other, as well as closing they are also closed with the help of spring unit during operation. But for this The chosen construction is technically relatively complex and therefore also needs improvement.

The technical problem to which the invention aims to solve is a system of the structure described above. of the security cabinet, which will have perfect functionality and in particular the relevant casement door The possibility of applying pressure individually in normal operation on the be developed in such a way that is to ensure a safe closing operation.

In order to solve this technical problem, a safety cabinet according to claim 1 is provided.

The opening and closing movement of the leaf door in question is manual in normal operation. and/or motor driven. Mostly winged in normal operation manual operation of the door and manual pressure on the swing door implementation is in question. In line with the invention here, manual pressure on connection of another leaf door in normal operation compared to a flap door applied mechanical separation from the element is provided. At this point, the word is mostly the other flap door in question is mechanically separated in the described method (single) a connector is used.

Thus, only one desired swing door can be opened manually or can be closed, on the other hand, this opening/closing movement of the other winged door ensured not to be affected. This is with mechanical separation from the fastener. is carried out. Also during shutdown, i.e. a fire under the pressure applied with the help of the spring unit of both leaf doors instantly. is provided to switch to the closing position.

In order to provide this in detail, the relevant winged door from the two-winged door is self-joint. It is connected to the connection element with the assembly. The knuckle assembly is essentially a (single) a connecting rod that is rotatably connected to the fastener and In addition, a door hinge arm that is pivotally connected to the swing door is formed. In other words, connecting the relevant leaf door to the fastener The joint assembly envisaged for It consists of the specified connection joint arm and the door joint arm.

Here, there is also an articulated connection between the articulated arms. Except this connecting joint arm to the connecting element such that it can be articulated or rotated is connected. The same feature is the hinged door, which has a hinged connection between it and the leaf door. It also applies to the arm.

In normal operation of the respective leaf door, possibly alone, manually opening movement in order to perform the desired functionality during operation The hinge assembly of the leaf door, during which pressure is applied, is in normal operation. rests on the base of the fastener. Relevant joint in accordance with the invention Two supports are provided on the fastener for the assembly. Meet that the abutments are on the door side, that is, the abutments It is foreseen that they are connected to the element in the direction of the leaf door.

For this purpose, the coupling element is usually symmetrically mounted with respect to the central guide (mirror). is designed. It will also form a right angle on a mounting plate of the abutments. It has been proven to be advantageous to arrange them in such a way. In this case the connection plate and two abutments on the door side practically in one go. can be created. The coupling element is essentially the rotating part of the respective joint assembly. the connection in question, which is usually equipped with axes of rotation for contains the plate. Here also, the references in question are among themselves. It has proven to be advantageous for them to create a wide angle.

In this way, the design generally consists of the joint connecting the casement door to the fastener. assembly is in the opening position of the relevant winged door, that the fastener belonging to this door It is applied in such a way that it leans against the support on the door side. On the other hand, winged In the closing position of the door, the hinge assembly in this case is usually in question. It is located at a distance to form an angle with the stop on the door side.

The design also provides pressure during the opening and closing motion (in normal operation). The applied hinged door hinge assembly will be displaced according to the fastener. is applied in sequence. In other words, fastener opening in normal operation maintains its position. This opening position of the fastener (normal in operation), it is related to the end position on the door side according to the manual. So link In the opening position (in normal operation), the wing door (closed) are located next to each other - almost oppositely.

The connector is generally in this opening position. of the connector eg switching to the closing position in the event of a fire along the guide refers to the operation. Fastener guide in closing operation moves from the opening position to the closing position. Here at the same time. If they are open, one or both of the swing doors will close.

The closing position of the fastener and with it, for example, in the event of a fire The closing operation is usually performed on the fastener as described above according to the manual. It makes it almost centrally located. length of this manual direction follows the opening/closing direction of the fastener. General rule, connection is the transverse extension of the element relative to the guide. As mentioned earlier, the link The opening position of the element is related to the end position on the door side according to the guide.

In this way, on the relevant winged door alone or independently of the other winged door. Additionally, pressure can be applied manually in normal operation, for example. related winged The procedure for opening the door is essentially the hinge assembly in this normal operation. It allows it to move according to the connector element. The joint arrangement is essentially so that there is an angled distance between the fastener and its corresponding stop. it moves. The connector remains motionless. This is from the connector in question It also applies to the other mechanically separated leaf door.

In the opening position of the manually pressurized flap door, this door It rotates or opens at least 90° according to the cabinet body it belongs to. fastener - more as explained before - it maintains the opening position. Of course, if necessary a larger opening angle is also realized. On the other hand, the closed winged door joint assembly without changing with the connecting rod stays in the leaning position.

The fastener does not open in normal operation until the spring unit is activated. stays in position. The connector is essentially in the opening position and the door It is fixed in the end position on the side. This fixation but not closing disabled in operation. This is a thermally triggered fire in the event of a fire. It can provide a melted solder connection. In this way, the spring unit is no longer connected to the fastener. The guide can move along the closing position.

Spring unit that grips the fastener in case of fire, that is, in closing operation accordingly, by pulling on an open leaf door or both open leaf doors. makes it close. This is because on the fastener of the spring unit, this from the end position on the door side where it was previously located to the guide or opening position relative to the closing position and with it according to the manual above pressure so that it moves to the almost central position described is the application. Opening wing door connecting rod together with fastener depending on the closing operation, as it rests on its abutment on the door side. The guide or opening due to the pressure exerted on the fastener position of the fastener from the end position on the door side according to the guide switching to the closing position where it is in the central position, the opening of the swing door makes it understandable.

Closing from the opening position by the spring unit of the fastener position, the connection element to the relevant leaf door Pressure is applied to close it over the joint assembly that leans on its abutment.

Thus, in the closing operation, the subject of the invention is the security cabinet in any case. locking and safe handling of the dangerous substances in it in the event of a fire. It is ensured that it is preserved in such a way. At this point, the main advantages are seen.

The invention is via a drawing below which only shows an example of an application. has been explained in detail. Here, Figure 1 shows the safety cabinet subject to the invention with closed wings in the closing operation. with doors and Figure 2 shows the Figure 1 object with an open flap door in normal operation.

In the figures it is a security with a cabinet body (1) to which the hinged doors (2) are attached. cabinet shown. The corresponding leaf door (2) is located on the side of the cabinet body (1). it is connected to the cabinet body (1) via a rotation axis (3). Both cabinet body (1) and its associated flap doors (2) non-combustible or hardly flammable It has an inner coating (4, 5) which may consist of plates made of material. Front On the other hand, it is connected to a fastener (7) that moves together in a guide (6). The two-winged door (2) is seen.

Also in the figures, the center of the fastener (7) is substantially larger than the guide (6). It is seen that the axis is designed symmetrically. Also fastener (7) it extends substantially transversely to the longitudinal direction of the guide (6). This Except for the guide (6), the relevant hinged door (2) or the connecting element (7) is designed to extend through a closing movement indicated by an arrow, and has been arranged. The same is true for the opening direction extending in the opposite direction.

Application of the fastener (7) with a roller assembly, a bridge, a wedge or the like For example, it can fit inside the guide (6), which includes two rails with a central recess.

The connector (7) is in each case along the guide (6), the normal connection of the connector (7). in operation, as in Figure 21, in the end position on the door side according to the guide (6). from its opening position as shown in Figure 1, according to the guide (6). It shifts linearly with the transition to the closing position in the position.

The closing position of the connector (7) in Figure ”l” is in the closing operation, For example, it shows its position at the time of fire.

In this closing position of the connector (7), the connector extends longitudinally. it takes an almost central position relative to the guide (6). Conversely, the link element (7) in the opening position shown in Figure 1 and accordingly normal the fastener (7) in operation, the end on the door side according to the aforementioned guide (6) switches to position.

The corresponding leaf door (2) is attached to the fastener (7) by means of a hinge assembly (8, 9) is connected. The joint assembly (8, 9) is essentially connected to the fastener (7). a connecting joint arm (8) and its associated winged door (2) consists of a door hinge arm (9) connected to turn. Connection There is also an articulated connection between the knuckle arm (8) and the door knuckle arm (9).

Joint assembly (8, 9) of the leaf door (2) where pressure is applied during the opening movement it rests on the abutment (10) of the fastener (7) in normal operation (see Fig.

Left-wing door (2) in figure 2. Essentially relevant on the connector (7) Two stops (10) are provided on the door side for the hinge assembly (8, 9). Aforementioned the abutments (10) are perpendicular to a mounting plate (11) as a component of the fastener (7). connected with an angle. In this context, the connection plate (11) and its the abutments (10) are relatively easy and cost-effective, i.e. the metal usually used It is produced by punching and bending processes.

The connecting plate (11) is equipped with axes of rotation (12), with the help of which the joint assembly (8, 9) is connected to the connector (7) in such a way that it can rotate. Relating to The connecting rod (8) is mainly connected with the help of the rotation axes (12). element (7) or its connection plate (11) so that it can rotate. Two It is seen that the basis (10) creates a wide angle between themselves.

From the point of view of the invention, an opening or opening of one of the flap doors 2 in normal operation from the connecting element (7) of the related other leaf door (2) during the closing movement. mechanical separation is of particular importance. The flap door in question (2) manual opening or closing motion application example in normal operation is carried out. In principle, a motor-driven opening of the swing door (2) or closing movement is also possible. The way it works is as follows: According to Figure 2, the normal operation of both leaf doors (2) starting from a closed position, one of the left-wing door (2) in this example a relative position of the opening movement with respect to the fastener (7) in the hinge assembly (8, 9). appears to be moving. Connector (7) in normal operation. 2, i.e. in the end position according to the relevant guide (6) remains. The connecting element (7) is fixed in this opening position. This is thermally by a fire safety triggered and not detailed here can be provided.

The leaf door (2) in question - in this embodiment the left-wing door (2) - in this case the joint assembly (8, 9), which belongs to it, if opened manually, from the position it has taken and forming an angle with respect to the fastener (7). in a position where the knuckle assembly (8, 9) rests against the left stop (10) in the exemplary case. passes. When the abutment (10) is reached, in the example case in Figure 2, the hinged door (2) the possible opening angle is limited to approximately 90° with respect to the cabinet body (1). This it only serves as an example.

Fastener (7) in the described opening movement of the swing door (2) (left) - description as it is - it maintains the end position on the door side with respect to the guide (6). This, represents normal operation. (Right) leaf door (2) correspondingly closing remains in its position. This is the hinge of the hinged door (2), which is closed. without changing the position of the assembly (8, 9) forming an angle with respect to the corresponding support (10). remains possible. Biplane in normal operation in Figure 2 As can easily be seen in the comparison of the door (2), the connecting rod (8) from the open position of the swing door (2) to the stop (10) it moves from its reclined position to the position where it forms an angle with respect to the fulcrum. Here The double-leaf door (2) is independent of the relevant fastener (7) and at the same time from it. Since they are mechanically separated, they are operated independently of each other.

The closing operation, for example, in the event of a fire, triggers a spring unit (13). it provides. This means that in the event of a fire, the fastener (7) is in the open position or in the guide. (6) the fire safety, which fixes it in the end position on the door side, is thermally possible because it is triggered. In this way, the spring unit can now close the fastener. it can pull it along the guide (6) in the direction of its rear side. Simultaneous connector (7) Fig. It moves from the opening position in Figure 2 to the closing position in Figure 1. This is closing In this process, both winged doors (2) - if they are open - are closed at the same time.

The reason for this is that the fastener (7) is moved from the opening position in Figure 2. 1 in the movement towards the back of the cabinet to the closing position in one or If both wing doors (2) are open, this movement of the fastener (7) its subject is to ensure that the winged door (2) is closed.

It is attached to the hinge (10) of the hinge assembly (8, 9) when the leaf door (2) is open. a closing movement or fastener (7) as a result of aging. The swing door transition from the opening position in 2t to the closing position in Figure 1t. (2) It is due to a direct application of pressure on '. This As a result, both flap doors (2) are in closing operation or in fire. shuts down instantly.

The closing position of one or both leaf doors (2) in this closing operation the guide (6) with the help of the fastener (7) spring unit (13). throughout, the leaf door (2) moves without applying any pressure on it.

This is because in this process, only the connecting rod (8) is the angle-forming from its position to the position where the fastener (7) rests on its stop (10). is to be passed. At this point, the main advantages are seen.
