Description

 Cabinet, especially gas bottle cabinet Description:

The invention relates to a cabinet, in particular a gas cylinder cabinet, with a cabinet body, and with at least one passive-wing cabinet door with espagnolette locking and at least one wing-door cabinet door with latch locking.

Such a cabinet and in particular gas cylinder cabinet is known from practice. Similar embodiments are presented in the utility model DE 81 25 571 U1. Such cabinets and in particular gas cylinder cabinets are characterized in that the passive leaf cabinet door can be locked to the cabinet body, whereas the aerofoil cabinet door is locked to the fixed cupboard door. This has the consequence that after unlocking only the door sash cabinet door can be opened easily and immediately, whereas the pigeon-cupboard door is still locked to the cabinet body. Usually locking pins are used at this point, which interact with attached to the respective cabinet door mushroom heads and must be moved relative to these for unlocking. This typically requires considerable effort and is not very comfortable. Fixed wings and wings are usually known from window sashes, but also door wings, which are equipped with a drive rod locking. Such a drive rod locking is described by way of example in the published patent application DE 42 18 909 A1. Among the aforementioned problems, the cited prior art has not provided a convincing solution. Here, the invention aims to provide a total remedy.

The invention is based on the technical problem of further developing such a cabinet so that the locking and unlocking in particular

is simplified and the possibility of a quick and easy door opening is created.

To solve this technical problem, a generic cabinet within the scope of the invention is characterized in that both the espagnolette lock on the fixed-wing cabinet door and the tab lock on the pedestrian cupboard door and thus both cabinet doors are simultaneously unlocked / lockable by means of a common rotary latch. In other words, both the espagnolette lock and the tab lock are designed so that they can spend at the same time in the unlocking / locking position using the common rotary latch. This considerably facilitates the operation of the two cabinet doors. In addition, both cabinet doors can thereby simultaneously open and close and lock. Here are the main benefits.

According to an advantageous embodiment, the rotary latch is formed at least in two parts with a subsequent tongue on the passive leaf cabinet door and an interacting bolt on the wing-cabinet door. To act on the bolt usually serves an externally arranged on the pedestrian-cabinet door actuator, which also acts on the bolt carrying a guide tongue. The actuator is an operating handle, an actuating knob, etc .. The actuator is regularly acted upon by rotation. As a result, the guide tongue and with it the bolt and consequently the follower tongue also undergo a rotation.

It has proven useful if the subsequent tongue has a guide for the bolt engaging therein. In addition, the secondary tongue is usually L-shaped

designed. The bolt is in contrast arranged on the already mentioned guide tongue.

It has also proved to be favorable when both tongues, that is, the guide tongue and the secondary tongue are placed in the middle compared to the longitudinal extent of the respective associated cabinet door. In addition, the design is usually chosen so that overlap both tongues in the closed state of the cabinet doors. In this way, a first central closure point for the respective cabinet door is provided by the overlapping tongues in the central area of the respective cabinet door.

In this context, it has further proven, when the two tongues are in the unlocked state at an angle and in the locked state approximately in a line to each other. The change from the angled to the straight arrangement and vice versa is achieved by means of the actuator on the pedestrian cabinet door. For this purpose, it is only necessary to apply the actuator rotating. The rotation of the actuator causes the connected to the actuator guide tongue and with it the bolt are also pivoted.

Since the follower tongue interacts with its guide with the bolt on the guide tongue or the bolt abuts the guide respectively engages in this, the described pivotal movement of the guide tongue and thus the subsequent tongue causes the two tongues occupy their angular position to each other or approximately are arranged in a straight line to each other.

At the same time, the described movement of the tongues causes the drive rods or actuating rods to be displaced in a linear direction. In fact, two drive rods are connected to the subsequent tongue. The guide tongue is in contrast connected to two actuating rods. In this case, a respective tab on the pedestrian cabinet door is rotated by the actuating rod in rotation. The respective tab on the pedestrian cabinet door can engage in an associated slot on the pedestal cabinet door. In general, two tabs are each provided in approximately the end of the associated actuating rod. One tab is located on the head side of the pedestrian cabinet door, while the other tab is provided on the foot side. The two tabs on the wing door also define closure points, so that in connection with the bolt or the guide pin carrying the bolt a total of three locking points in the form of the two tabs and the bolt or the guide tongue are formed on the wing cabinet door.

Also, the passive-wing cabinet door has a total of three closure points. In fact, the two connecting rods connected to the follower tongue are designed so that they engage in the respective hollow bores foot side and head side of the cabinet body in the closed state of the passive leaf cabinet door. In this way two closing points for the passive leaf cabinet door are defined. For this purpose, there is the subsequent tongue, which also represents a closure point, so that the passive-wing cabinet door is equipped with a total of three locking points, namely the subsequent tongue and the two end-side pin on the drive rods. These pins engage in the associated hollow holes on the head side and the foot side of the cabinet body in the region of a door opening plane.

That is, the two cabinet doors are in the closed state by the two tabs on the pedestrian cabinet door and the two tongues of the rotary latch releasably coupled together. In addition, both cabinet doors are in the closed state at least three points with each other and / or bolted to the cabinet body.

In this way, a particularly durable lock is provided, because the respective cabinet door is determined at each head end, foot side and center on her the other cabinet door facing door edge. The opposite edge of the door is usually anchored with two bearing pins on the head end and the foot side rotating in the cabinet carcass. At the same time, both cabinet doors can be unlocked and locked with one hand. For this is done via the actuator, which is advantageously provided on the pedestrian-cupboard door, but in principle can also be connected to the passive-cupboard door. Here are the main benefits.

In the following the invention will be explained in more detail with reference to a drawing showing only one exemplary embodiment; show it:

1 shows a cabinet according to the invention in a perspective view,

FIG. 2 shows a view from the inside onto the cabinet doors and FIG. 3 shows an enlarged detail from FIG. 2.

In the figure 1, a cabinet is shown, which is designed in this case as a gas cylinder cabinet. Of course this is not restrictive. In fact, the cabinet has a cabinet body 1 and two cabinet

Doors 2, 3. Inside the cabinet body 1 a plurality of merely indicated gas cylinders 4 are received and are here, for example, secured in a holder standing. The two cabinet doors 2, 3 are designed as swing doors 2, 3. For this purpose, the two cabinet doors 2, 3 on their body side door edge on pivot 5, by means of which they are rotatably mounted in the cabinet body 1. In principle, the pivots 5 can also be anchored in the cabinet body 1, so that the cabinet doors 2, 3 are inserted therein. Of course, mixed forms are also encompassed by the invention.

The one cabinet door 2 is designed as a fixed-wing cabinet door 2 and the other cabinet door 3 as a pedestrian-cupboard door 3. The difference between the two cabinet doors 2, 3 in conjunction with the varying notation can be explained due to the fact that the passive leaf cabinet door 2 by means of a drive rod lock 6, 7 firmly locked to the cabinet body 1, the pedestrian cabinet door 3 via a Laschenverriegelung 8, 9, 10 has, with the help of the pedestrian cabinet door 3 is lockingly coupled to the passive leaf cabinet door 2 and the rod lock 6, 7 with the cabinet body 1.

In the context of the invention can now both the espagnolette 6, 7 on the fixed-wing cabinet door 2 and the tab lock 8, 9, 10 on the wing door 3 and thus both cabinet doors 2, 3 by means of a common rotary latch 7, 10, the first 1 at the same time unlock and lock. The rotary latch 7, 10, 1 1 is at least in two parts and has a follower tongue 7 on the passive leaf cabinet door 2 and a thus interacting pin 1 1 on the pedestrian cabinet door 3. Actually, the pin 1 1 on the pedestrian-cupboard door 3rd supported by a guide tongue 10.

In contrast, the passive leaf cabinet door 2 is equipped with the already mentioned subsequent tongue 7.

That is, the rotary latch 7, 10, 1 1 is composed in the example of the subsequent tongue 7, the guide tongue 10 and connected to the guide tongue 10 pin 1 1 together. Thus, the pin 1 1 can interact with the follower tongue 7, the subsequent tongue 7 has a guide 12, on which or in which the pin 1 1 engages upon actuation of the guide tongue 10 and slides along it. For actuation of the guide tongue 10, an actuating member 13 is provided on the outside of the door leaf cupboard door 3, which is indicated only in the figure 1. In the present case, the actuating member 13 on the outside of the door leaf cupboard door 3 is a rotary knob, a rotary handle, etc. With the aid of the rotatable actuating member 13, the guide tongue 10 can be pivoted about its axis 15, as indicated by corresponding double arrows in FIG is indicated and an arrow in the counterclockwise direction in Figure 3 illustrates. In fact, the guide tongue 10 and the actuator 13 are arranged coaxially in comparison to the common axis 15, wherein the actuator 13 is rigidly coupled to the guide tongue 10 in the example case.

A rotation of the guide tongue 10 - starting from the unlocking position of Figure 3 - in the counterclockwise direction about the axis 15 causes the borne by the guide tongue 10 pin 1 1 engages the Fußflügel-cabinet door 3 in the guide 12 of the subsequent tongue 7. In this process, the subsequent tongue 7 is also pivoted, in a clockwise direction about its associated axis 14. The corresponding arrows in the figure 3 indicate. This process corresponds to the fact that both tongues 7,

10 or the rotary latch 7, 10, 1 1 is acted upon as a whole in the direction of a lock. This then applies equally to the two cabinet doors 2, 3. The subsequent tongue 7 is designed substantially L-shaped. The guide 12 on the follower tongue 7 can be found on the predominantly horizontally extended long L-leg, whereas a drive rod 6 is connected to the comparatively short L-leg. Another drive rod 6 is connected to a relative to the short L-leg of the follower tongue 7 protruding nose 16.

Compared to the longitudinal extent of the respective cabinet doors 2, 3, the two tongues 7, 10 are placed approximately in the middle. In addition, it can be seen from the figure 2 that overlap both tongues 7, 10 in the closed state of the cabinet doors 2, 3. This is primarily the nose 16. In addition, the long L-leg of the L-shaped follower tongue 7. As already explained, two drive rods 6 are connected to the subsequent tongue 7. In this way, the two drive rods 6 in conjunction with the follower tongue 7 define the previously discussed drive rod lock 6, 7 on the passive-wing cabinet door 2.

The pedestrian cabinet door 3 is equipped with the already mentioned central guide tongue 10. At the guide tongue 10 two actuating rods 8 are connected. The actuating rods 8 interact with tabs 9. In fact, in each case a tab 9 is arranged in the head area and a tab 9 in the foot region of the relevant question door panel door 3. An action on the guide tongue 10 and an associated linear movement of the two actuating rods 8 corresponding to the double arrow in Figure 2 and 3 corresponds to that with the respective

Actuating rod 8 interacting tab 9 performs a direction indicated by a double arrow pivoting movement.

With the aid of this pivotal movement of the tab 9 about its associated axis 17 can be achieved that a pin 18 of the tab 9 engages in each case in an enlarged shown in Figure 2 slot 19 of the fixed-wing cabinet door 2. This is true at least for the locking position of the two cabinet doors 2, 3. That is, the two cabinet doors 2, 3 are in their closed state shown in Figure 2 by the two tabs 9 and the two tongues 7, 10 of the rotary latch 7, 10 1 1 releasably coupled together. In addition, both cabinet doors 2, 3 in the closed state at least three points with each other and / or with the cabinet body 1 is boltingly connected. In fact, the two tabs 9 and their pins 18 in conjunction with the guide tongue 10 define the three locking points on the pedestrian cupboard door 3. In contrast, the passive leaf cabinet door 2 has three locking points, on the one hand by the subsequent tongue 7 and on the other hand by two locking pin 20th end of the drive rods 6 are formed. For the two locking pins 20 end of the drive rods 6 engage in only indicated hollow holes 21 in the cabinet body 1 in the locked state of the passive leaf cabinet door 2 a.

For this purpose, the guide tongue 10 has to be pivoted about its axis 15 in the counterclockwise direction, as indicated by the arrow 3 already referred to in FIG. In this process, the two drive rods 6 are linearly moved according to the double arrow in Figure 2, in such a way that the locking pin 20 in the respective hollow bore 21 on the one hand on the head and on the other hand the foot

Cabinet body 1 intervene. For this purpose, the loading of the guide tongue 10 as already described above, and which entrains the follower tongue 7 during its pivoting movement. In this connection, the two cabinet doors 2, 3 ensure that a door opening plane 22 in the cabinet body 1 is closed. For this purpose, the two hollow bores 21 can be found in the region of this door opening plane 22 in the cabinet body 1, on the one hand on the head end and on the other hand on the foot side of the cabinet body 1 in question.

The operation is as follows. Starting from the unlocking position according to FIG. 3, an actuation of the actuating member 13 such that the guide tongue 10 is pivoted about its axis 15 in the counterclockwise direction, ensures that the pin 1 1 carried by the guide tongue 10 engages the guide 12 on the following tongue 7. As a result, we raised the follower tongue 7. In this process, the two go in the unlocked state of Figure 3 at an angle to each other tongues 7, 10 in a more or less straight arrangement to each other. At the same time in this case the drive rods 6 are driven with their end locking pins 20 in the hollow holes 21. This is indicated by the dashed arrow in the locking direction in FIG.

The actuating rods 8 are moved according to the dashed arrow in Figure 3. In this way, the actuating rods 8 ensure that the tabs 9 are pivoted about their respective axes 17 in the counterclockwise direction of Figure 2. For this corresponds - as I said - the movement of the actuating rods 8 in the direction indicated by dashed arrows in Figure 3 locking direction. As a result, the pins 18 provided on the tabs 18 engage in the slots 19.

As a consequence thereof and at the end of this movement, the two cabinet doors 2, 3 are locked against each other and against the cabinet body 1. This is done in the course of a single rotational movement of the actuator 13. The unlocking can be realized only by a single rotational movement by means of the actuator 13 on the pedestrian-cupboard door 3. Then the application takes place in the opposite sense as previously described. These include the respective solid arrows in Entriegelungsrichtung in the figure 3.
