Description

• einen Arbeitsraum, in dem eine Röntgenapparatur anordenbar ist,
• Schutzelemente, insbesondere bleihaltige Wände und/oder Bleiglasscheiben, die für Röntgenstrahlung undurchlässig sind und den Arbeitsraum einschließen,
• wenigstens eine Tür zum Öffnen und Verschließen eines Zugangs zum Arbeitsraum des Sicherheitsgehäuses,

wobei die Tür mindestens ein für Röntgenstrahlung undurchlässiges Tür-Schutzelement, insbesondere eine Bleiglasscheibe, aufweist,
wobei durch das mindestens eine Tür-Schutzelement der Zugang zum Arbeitsraum vollständig abdeckbar ist,
und wobei die Tür relativ zu einem Hauptrahmen des Sicherheitsgehäuses um eine Achse S verschwenkbar ist.The invention relates to a security housing for an X-ray apparatus, comprising

• a work space in which an X-ray apparatus can be arranged,
• Protective elements, in particular lead-containing walls and / or lead glass panes, which are impermeable to X-ray radiation and enclose the working space,
• at least one door for opening and closing an access to the working space of the security housing,

the door having at least one X-ray impermeable door protection element, in particular a lead glass pane,
wherein the access to the working space can be completely covered by the at least one door protection element,
and wherein the door is pivotable about an axis S relative to a main frame of the safety housing.

Such a security housing has been used for example in the commercially marketed X-ray spectrometer "D5000" Bruker AXS GmbH, Karlsruhe.

X-radiation is used in a variety of ways in diagnostic and analytical procedures. X-ray diffractometry, for example, is a powerful method of instrumental analysis in which information about the atomic structure, in particular crystal structure, of a sample is obtained by diffraction of X-rays on the sample.

The use of X-rays is basically dangerous for humans. Exposure to intense X-ray radiation can locally lead directly to burns of the human tissue and the formation of tumors; In the long term, X-rays can be carcinogenic even at lower doses in the whole organism. For this reason, X-ray radiation is shielded as much as possible during use.

For X-ray diffractometers and other X-ray equipment, it is therefore customary to operate them in radiopaque safety housings (protective housings). During operation the safety housing is closed. For manipulation of the X-ray apparatus, however, this must be made accessible. In an X-ray diffractometer, for example, the safety housing must be opened for a sample change.

Very common are hinged doors. Usually, the hinged door of a protective housing is pivotable about a vertical axis. The hinged door covers the access to the working area during operation of the X-ray apparatus, and is opened for sample exchange. The hinged door is typically sufficiently large to allow an X-ray apparatus to be installed in or out of the working space when fully assembled. Due the size of the door requires a relatively large amount of free space to open the hinged door before access

In scientific laboratories, a large number of devices often have to be accommodated and operated in a small space, so that there is often a shortage of space. The work on different devices should not hinder each other, especially not spatially.

The protective housing of the D5000 provides a large hinged door that covers all access to the workspace, with a second, smaller hinged door in the large hinged door. For a sample change, it is sufficient to open the second, smaller hinged door, for which only relatively little space is required before the access of the safety housing. For a shipment of a mounted X-ray apparatus, the large hinged door can still be opened.

In addition, it is known to cover the access to the working space of a security housing with a folding door; this is the case with the X-ray spectrometer "D8" from Bruker AXS GmbH, Karlsruhe. The folding door only needs to be partially opened for a sample change, which also requires relatively little free space in front of the access.

Object of the invention

The invention has for its object to further reduce the need for free space before access to the working space of a security housing described above.

Brief description of the invention

This object is achieved by a safety housing of the type mentioned, which is characterized in that at least one door-protection element of the door is formed on a sliding door, wherein the sliding door is slidably mounted on a sash of the door in a direction V, and that of Sash of the door relative to the main frame about the axis S is pivotable.

The invention proposes to provide an additional sliding door function on a door with pivoting function ("hinged door"). About the pivoting casement, with which the sliding door is pivoted, the entire access to the working space can be opened inside the protective housing. This is particularly useful for deploying mounted X-ray equipment. If only a minor manipulation of the X-ray equipment is necessary (such as a sample change or an adjustment), the sliding door function can be used with the sash closed. In particular, the sliding door does not require any free space in front of the access, so that in case of lack of space in the laboratory for normal operation, no minimum distance to any other laboratory equipment arranged opposite needs to be maintained. In the case of a sliding door narrow in the direction of displacement V, it can even be moved exclusively in front of the access without any need for free space; in the case of a wider sliding door, a space requirement only arises laterally of the access, which, however, usually relatively little affects the possibilities of using space in the laboratory.

In the present invention, a protective element than X-radiation is considered impervious if it causes an attenuation of the X-ray intensity in transmission to 1/1000 or less, an attenuation to 10 ^-6 -fold is preferably effected, as measured at the wavelength of Cu Ka radiation. The fact that the access is completely covered by the at least one door-protection element means that in a straight line on the access to propagating X-ray radiation from the Working space always meets a door protection element.

Preferred embodiments of the invention Embodiments relating to the division of the door

In a preferred embodiment of the safety housing according to the invention it is provided that access to the working space can be completely covered by the at least one door protection element of the sliding door, in particular wherein the sliding door comprises exactly one door protection element. In other words, the door has only door protection elements of the sliding door. This simplifies the structure. Through a single lead glass as the only door protection element can be granted a uninterrupted view of the work space.

In another embodiment, the at least one door protection element of the sliding door extends in a direction perpendicular to the direction V over the entire height of the door lockable access. Thus, the sliding door opens up as much of the access as possible without requiring additional space in front of the access.

• das oder die Tür-Schutzelemente der Schiebetür über einen ersten Teilbereich des Zugangs erstrecken, und
• das oder die starr am Flügelrahmen befestigten Tür-Schutzelemente über einen zweiten Teilbereich des Zugangs erstrecken,

wobei erster und zweiter Teilbereich zusammen die gesamte Breite des von der Tür verschließbaren Zugangs überdecken,
insbesondere wobei erster und zweiter Teilbereich überlappen. Bei dieser Ausführungsform ergänzen sich verschiebliche Tür-Schutzelemente der Schiebetür und im Flügelrahmen starre Tür-Schutzelemente. Bevorzugt werden beim öffnenden Verschieben der Schiebetür deren Tür-Schutzelemente über die im Flügelrahmen starren Tür-Schutzelemente geschoben, so dass kein freier Raum neben dem Sicherheitsgehäuse zum Öffnen der Schiebetür benötigt wird. Bei dieser Ausführungsform kann weiterhin der Flächenanteil von verschieblichen Tür-Schutzelementen der Tür verringert werden, um den Aufbau zu vereinfachen.Particularly preferred is an embodiment which provides
at least one door protection element is rigidly fastened to the casement, and that, with the casement closed and the sliding door closed, parallel to the direction V

• the door protection element (s) of the sliding door extend over a first portion of the access, and
• the door or the protective elements rigidly attached to the casement extend over a second portion of the access,

wherein the first and second subareas together cover the entire width of the door lockable access,
in particular wherein the first and second sub-areas overlap. In this embodiment, sliding door protection elements of the sliding door and rigid door protection elements in the sash frame complement each other. When opening the sliding door, its door protection elements are preferably pushed over the door protection elements that are rigid in the sash frame, so that no free space is required next to the safety housing for opening the sliding door. In this embodiment, moreover, the area ratio of slidable door protection members of the door can be reduced to simplify the construction.

Also preferred is a further development of this embodiment, in which, with the sash frame closed and the sliding door closed, the first subarea extends approximately over half the width of the access parallel to the direction V. The second portion also extends about half the width of the access (namely the other half). This opens up the largest possible amount of access by opening the sliding door without the need for free space next to the security enclosure.

Furthermore, an embodiment is preferred in which, when the sliding door and the sash frame are closed, the door protection element (s) of the sliding door cover access to the working space in an edge region of the access remote from the axis S, and the sliding door moves from its closed position in the direction of the door Axis S is too pushed. This reduces bearing forces on the hinges (hinges, hinges) of the casement with the sliding door open. Furthermore, in this case, a combined operation of sash and sliding door with the same handle and actuator easier by hand.

Embodiments relating to the locking mechanism

An embodiment of the safety housing according to the invention, which is characterized in that
a bolt is provided with which the casement can be locked and unlocked in its closed state relative to the main frame,
in that an actuating element which can be moved with the sliding door and which can be switched between a first position and a second position is arranged on the sliding door,
wherein in the first position of the actuating element the actuating element does not hinder a movement of the sliding door on the casement and the method of the sliding door does not influence the locking position,
and wherein in the second position of the actuating element, the actuating element engages in the bolt or in a driver which is rigidly connected to the hinge or hinged thereto, so that actuated with the sash closed by moving the sliding door in the second position of the actuating element of the bolt becomes.

With this embodiment, a simple and safe operation of both the sash function (swinging or unfolding the sash or the entire door) and the sash function (sliding door with the casement closed) is possible. The sliding door has an actuator, which is preferably integrated in a seated on the sliding door handle. The actuator may be switched by a human operator (at least at and preferably only with the sash closed) between the first and second positions, such as by exerting a compressive force on the actuator.

In order to operate the sliding door function, the actuator is in the first position. In this first position it is provided that the bolt locks the casement so that it is held in the closed position. By a manual pull on the side the sliding door (or an associated handle), this can then be moved relative to the sash to release a portion of the access to the work space. The first position is the default position for the actuator; the actuator is typically biased to this first position.

In order to operate the sash function, the actuator is switched to the second position. By a manual lateral pulling on the sliding door, the bolt is then actuated and the sliding door also moved relative to the casement, but typically only in a narrow area ("Entriegelungsweg"). Once the latch is unlocked, the sash can be opened by pulling the sliding door forward.

In the embodiment according to the invention can be switched over in the simplest way between the two operating modes of the door mechanism (sliding door function and gullwing function); it only takes one actuator and the sliding door (or associated handle) to be handled. Preferably, the actuation of the various modes of operation are mutually exclusive by interlocks and detents, i. when the sliding door is pushed open, the hinged door can not be unlocked and the sliding door can not be opened when the casement is open. In particular, the switching of the actuating element from the first position to the second position is preferably blocked when the sliding door is not closed.

A particularly preferred development of the above embodiment provides that in the second position of the actuating element associated with a closed sliding door latch position locks the casement, and a belonging to a sliding door sliding latch position releases the casement. In this embodiment, it is sufficient, only one To operate the single safety interlock per door of the safety enclosure to ensure operation. The safety lock only needs to check or secure the closed state of the sliding door, because then in this case, the hinged door is inevitably locked.

Preference is also a development in which the range of movement of the sliding door away from the closed position in the second position of the actuating element is limited by a mechanical stop on a Entriegelungsweg EW which is shorter than the possible sliding path SW of the sliding door in the first position of the actuating element , in particular where EW ≤ 0.2 * SW,
and in particular where EW ≤ 5 cm. The mechanical stop marks a sliding door position in which the latch is unlocked; Another purpose-free and tedious process of the sliding door is prevented. When pivoting the sash, the sliding door is largely closed, so that the sliding door does not hinder the opening of the sash.

Preference is given to a refinement of this, which provides that a blocking mechanism is formed on the door, which blocks a movement of the sliding door out of the displacement position of the sliding door on the mechanical stop when the casement is not closed and in the second position when the actuating element is in the position.
in particular, wherein the wing frame, a movable locking member is provided, which is biased by spring force into a locking position in which it blocks the travel of the actuating element or the bolt or the driver in the second position, and which rigidly when the casement is closed by interaction with a main frame trained counter-means is pushed out of the travel of the actuating element or the bolt or the driver in the second position. This further development prevents incorrect operation of the door mechanism (in particular locking mechanism); the over the actuator operated latch remains in the unlocked position with the sash open to ensure easy closing of the sash. The blocking of the sliding door on the mechanical stop is typically carried out by a positive connection with a locking element which is movably mounted on the casement. This positive connection can most easily be done directly with the actuator, or with the latch or any driver, which are each coupled to the actuator, whereby the sliding door is blocked.

In another development, a locking mechanism is provided, with which a movement position of the sliding door can be locked on the mechanical stop. This also prevents incorrect operation of the door mechanism can be prevented.

For example, the locking mechanism comprises a resilient ball in the sash, which engages in a recess on the bolt. As a result, a resistance to sliding door procedures is established; This is very easy to realize.

In another example, the locking mechanism is arranged by a third position of the actuating element, in which a holding element of the sash block blocks a method of the actuating element, in particular
wherein the actuating element is driven by spring force from the second position to the third position, and in particular wherein the third position between the first and second position is formed.

In a particularly preferred embodiment, a guide is provided on the casement, which holds the actuating element in the second position when the sliding door is moved in the second position of the actuating element from the closed position of the sliding door, and which switching between first and second position only at closed Sliding door allowed. As a result, incorrect operation of the door mechanism (in particular locking mechanism) is also prevented, in particular, the sliding door can not be moved normally (ie, as in the first position of the actuating element) when the sash is open.

A preferred further development for this provides that the guide comprises a slot through which the actuating element (in the second position) at a constriction of the actuating element is feasible, and that the slot has a widening at which the actuating element with the sliding door between the first and second position can be switched. Thus, the guide can be easily realized mechanically. The expansion is typically at one end of the slot.

Also preferred is a development in which the actuating element comprises a retractable and retractable pin, which is biased by spring force into a retracted position corresponding to the first position of the actuating element, and which with muscle force in an extended position, the second position corresponds to the actuating element, can be pressed. This simplifies the use of the most frequently operated sliding door function, and makes it more difficult to activate the hinged door function by mistake.

Also preferred is a development in which the bolt on the casement is slidably mounted in a direction R, wherein the direction R and the direction V are parallel. The storage and management of the bolt on the casement facilitates the control of the bolt on the actuator.

Alternatively, the bolt on the main frame can be slidably mounted in a direction R ', wherein the direction R' and the direction V at parallel closed sash. In this case, the locking mechanism can be made particularly robust more robust.

Particularly preferred is also a further development, which is characterized in that an electronic security module is provided on the main frame, which monitors the closure of the access to the working space with the door for the operation of an X-ray apparatus in the working space, which releases X-rays during operation,
wherein the security module for the operation of the X-ray apparatus ensures the presence of an actuator in the security module,
that the actuator is rigidly attached to the sliding door,
and the safety module is designed such that the actuator can only be engaged and executed by sliding the sliding door into the safety module when the casement is closed, wherein the position of the actuator introduced in the safety module corresponds to the closed position of the sliding door. The safety module ensures that X-ray radiation is not put into operation without a presence actuator, and / or that X-ray radiation is switched off immediately in the absence of the actuator in the safety module, and / or blocking of the actuator in the safety module (thus blocking the opening of the safety enclosure) when the X-radiation is switched on. Any opening of the door, so the sash or the sliding door, requires a sliding door from the closed position and thus also the actuator from the security module, therefore, a single security module can monitor the access. It should be noted that according to the invention, an electronic actuation of the safety module, which usually takes place in the prior art via a separate probe, can be coupled within the scope of the invention to a use of the actuating element.

Other embodiments

A further preferred embodiment provides that the direction V, in which the sliding door is displaceable with respect to the casement, is perpendicular to the axis S. This has proven itself in practice; In particular, then the overall movement to open the sash easily from the hand. Typically, the axis S is vertical and the direction V is horizontal.

Also preferred is an embodiment in which the casement is C-shaped, wherein the open side of the C-shaped frame is remote from the axis S. This improves the accessibility of the working space, especially in a double-wing door assembly.

Finally, an embodiment is particularly preferred in which two adjacent doors are provided, the two doors forming two opposite wings of a double door, in particular wherein the door protection elements of the two doors overlap. Each opened by sliding door functions sections of access to the work space can then be shared.

The door (i.e., the sash including the sliding door) of a security housing according to the invention is further preferably designed aushängbar, for example by means of hinges on the main frame, from which the door can be lifted out. This simplifies the transport of the safety housing.

Further advantages of the invention will become apparent from the description and the drawings. Likewise, according to the invention, the above-mentioned features and those which are still further developed can each be used individually for themselves or for a plurality of combinations of any kind. The embodiments shown and described are not to be understood as exhaustive enumeration, but rather have exemplary character for the description of the invention.

The FIGS. 1a to 1c each show an inventive safety housing 1 for an X-ray apparatus, for example, an X-ray diffractometer or an X-ray fluorescence analyzer or other instrumental-analytical X-ray measuring device (not shown). The safety housing 1 encloses a working space 2 in the interior of the safety housing 1, in which the X-ray apparatus can be arranged. The security housing 1 has a plurality of stationary protective elements 3a-3c, which are opaque to X-radiation, for example, lead-containing side walls 3a, ceiling plates 3b and bottom plates 3c.

In the Figures 1a-1c towards the front of the working space 2 has an access 4, with the X-ray impermeable door protection elements 5a, 5b (here lead glass panes) can be covered. The door protection elements 5a, 5b belong to two doors 6a, 6b.

The doors 6a, 6b have a dual functionality. Each of the doors 6a, 6b has a (here C-shaped) wing frame 7a, 7b, which is mounted with hinges 8 pivotally mounted on a stationary main frame 9 of the security housing 1, see. Swivel axes S. The sash frames 7a, 7b in turn each store a sliding door 10a, 10b, which can be moved respectively on the sash frame 7a, 7b, cf. Moving direction V. Each sliding door 10a, 10b has a handle 11, in which a manually operable push button 12 of an actuating element is provided for locking operation.

FIG. 1a shows the security housing 1 according to the invention with closed sliding doors 10a, 10b and closed sash 7a, 7b, as it is necessary during an X-ray measurement to shield the X-rays released in the working space 2. In order to make a smaller manipulation, such as a sample change, in the working space 2, it is sufficient to open the two sliding doors 10a, 10b, whereby about half the width of the maximum possible access 4 is opened, see FIG. 1b , Only relatively little space left and right of the security housing 1 is required. If a major manipulation, such as replacement of the X-ray apparatus to be made in the working space 2, the casement 7a, 7b can be pivoted, wherein the (largely) closed sliding doors 10a, 10b are pivoted with, and the total, maximum access 4 is opened , please refer Figure 1c ,

The door mechanism preferably allows a movement of the sliding doors 10a, 10b only when the sash frame 7a, 7b is closed and, conversely, a pivoting of the sash frames 7a, 7b only in (largely) closed sliding doors.

In the embodiment shown, each door protection element 5a, 5b extends in each case over the full width B and the full height H of the area of the access 4 covered by the associated door 6a, 6b.

FIG. 2 shows another embodiment of a door 6a for a security housing according to the invention in a schematic frontal view.

The door 6a has a rectangular sash frame 7a (hatched, the hidden inner boundary is shown in phantom) which is hinged to the main frame (not shown) of the security enclosure and is rotatable about a vertical pivot axis S.

On the casement 7a, a door protection element 21 with (here) rivets 22 is rigidly secured. On the sash 7a also two rails 23 are attached, which extend over the entire width B of the door 6a and serve as a bearing for a sliding door 10a. The sliding door 10a is movable on the rails 23 in the direction V. The sliding door 10a has a door protection element 5a, which is movable with the sliding door 10a. The sliding door 10a can be handled via the handle 11.

In Fig. 2 the sliding door 10a is closed, so that the door 6a with the two door protection elements 21, 5a completely radiopaque covering the access to the working space behind it, in particular over the entire width B of the door 6a and the access. The rigid door protection element 21 covers a left partial area LTB and the door protection element 5a of the sliding door 10a covers a right partial area RTB of the door 6a or of the access. Both partial areas LTB, RTB correspond in each case to approximately half of the full width B, with a slight overlap. Both door protection elements 21, 5a extend over the full height H of the door 6a or the access behind it.

If the sliding door 10a is moved to the left out of the closed position, access to the working space is opened in the right-hand sub-area RTB. The sliding door 10a does not need any free space to the side of the door (about the left of the door) or in front of the door 6a, because the sliding door can easily be moved in front of the rigid door protection element 21. If full access over both subregions RTB, LTB is required, then the sash frame 7a is swung open.

The Figures 3a-3d schematically illustrate a door mechanism, in particular bolt mechanism, which can be used according to the invention in a security housing according to the invention. Different stages of operation are shown in schematic cross section.

FIG. 3a shows in a first operating mode (sliding door function) a door according to the invention with a sash 7a, which is pivotally mounted by means of hinges (hinges) 8 to a main frame 9 (shown in phantom). On the sash 7a a sliding door 10a is arranged (stored), which is displaceable in the direction V parallel to the sash 7a. An actuator 31 in a first (pulled out) position does not hinder the process of the sliding door 10a. The sliding door 10a can be extended by a maximum sliding distance SW (in the FIG. 3a indicated for the right end of the sliding door) are moved, which corresponds here approximately half the width of the sash 7a. The sliding path SW is limited in such a way to ensure the stability of the sliding door storage, and to limit the lateral space requirement (collision danger area).

On the other hand, the sash 7a is locked. A latch 32, which is mounted on the sash frame 7a displaceable in a direction R, engages with its right end in a (schematically shown) eyelet 33 of the main frame 9, so that the sash frame 7a can not be swung open.

FIG. 3b shows a first phase of the switching of the operating modes. When the sliding door 10a is closed (ie, the sliding door 10a is rightmost), the operating member 31 is retracted. The actuating element 31 then projects through the wing frame 7a in this second position and engages in a recess 32a of the bolt 32, so that the movement of the bolt 32 is coupled to the movement of the sliding door 10a.

Figure 3c shows the second phase of switching the operating modes. When the actuating element 31 is retracted, the sliding door 10a together with the actuating element 31 is now moved slightly to the left by the amount EW (unlocking path) until the latch 32 abuts the mechanical stop 34. The entrained latch 32 is pulled out of the eyelet 33. Thus, the sash frame 7a is unlocked. Note that here the Entriegelungsweg EW is about 1/5 of the maximum sliding distance SW.

3d figure shows the second operating mode (hinged door function) of the door. The sash 7a can be rotated about the hinge 8. In this case, the actuating element 31 typically remains in the second position, and preferably the sliding door 10a is locked in the displacement position on the mechanical stop 34 when the casement 7a is open (cf. Fig. 5a . 5b for a possible realization).

In the FIG. 3e is an alternative door mechanism according to the invention similar Fig. 3a shown. In this door mechanism, the latch 32 is not slidably mounted on the casement 7a, but on the main frame 9 in a direction R '. On the wing frame 7a a rigid eyelet 33a is formed, in which the latch 32 can engage to lock the wing frame 7a on the main frame 9. In Fig. 3e shown is the locked (and closed) state of the sash 7a. The actuator 31 is retracted (into the first Position), so that the sliding door 10a can be moved in front of the sash in the direction V, wherein the directions V and R 'are parallel.

The FIGS. 4a to 4c illustrate the door bolt mechanism of a security housing according to the invention with greater detail.

The cutouts each show a sliding door 10a, on which a handle 11 with an inserted, substantially pin-shaped actuating element 31 (with push button 12) is attached. The sliding door 10a is slidably mounted on a casement 7a by means of a rail (linear guide) 23. The sash 7a abuts a main frame 9 stationary in all door operations. In the casement 7a, a driver 41 is slidably mounted in a direction R. The driver 41 is rigidly connected to a latch 32, which can engage behind a hook fixed to the main frame 9 (only indicated with Bzz. The driver 41 has a recess 41 a for the engagement of the actuating element 31. Fixedly connected to the sliding door 10a is also an actuator 43, which can engage in a security module 44.

FIG. 4a first illustrates the sliding door function. The actuating element 31 is in a first position in which it does not engage in the recess 41 a. The actuating element 31 is biased by a compression spring 45 in this first position. The sliding door 10a can then be moved freely on the sash frame 7a in the direction V.

The bolt 32 engages behind the hook 42, so that the casement 7a is locked to the main frame 9 and in particular can not be pivoted forward.

In the in Fig. 4a shown position of the sliding door 10a (fully closed), the actuator 43 is retracted into the security module 44. In This position may be started and maintained in the safety housing an X-ray experiment.

FIG. 4b illustrates the first step for switching the operating mode. When the sliding door 10a is closed, the actuating element 31 is pressed in against the spring force. The front end of the actuating element 31 engages in this second position in the recess 41 a of the driver 41 a. In this case, a widening 46 of a slot 47 is penetrated, which is formed on the casement 7 a (see Fig. 4a ). A constriction 48 on the actuating element 31 is then at the level of the slot 47. It should be noted that the slot 47 allows the operating element 31 to be switched from the first to the second position only when the sliding door 10a is completely closed by the widening 46 (see FIG Fig. 4a ). The fully closed sliding door position is defined by an auxiliary mechanical stop 49a.

By the engaging actuator 31, the movements of the sliding door 10a and driver 41 and thus also of the bolt 32 are coupled together. If now the sliding door 10a with the actuating element 31 in the second, depressed position, moved to the left, the bolt 32 is taken over the driver 41, so that the sash frame 7a is unlocked. Note that the directions R and V are parallel.

Figure 4c shows the door mechanism with the thus moved to the left sliding door 10a with retracted latch 32, ie with unlocked sash 7a. The actuator 31 is included with its constriction 48 in the slot 47 and is left at the end of the slot 47 as a mechanical stop 49 ("unlocked position"). By the mechanical stop 49 of Entriegelungsweg EW the sliding door 10a is limited (Note that alternatively or additionally, the driver 41 or the latch 32 could go to a corresponding mechanical stop). Since the slot 47 engages in the constriction 48 (ie narrow engages), the actuator 31 can not spring back from the second, depressed position.

In the unlocked movement position of the sliding door 10 a, the actuator (the safety fork) 43 is completely pulled out of the security module 44. Thus, the actuator 43 does not interfere with the opening of the sash 7a.

The sliding door 10a is fixed in the abutting position of the mechanical stop 49 by a locking mechanism. In the example shown, the locking mechanism comprises two resilient balls 50 formed on the sash frame 7a, which engage in recesses (not shown) on the bolt 32. In order to move the sliding door 10a (and thus also the latch 42) with respect to the casement 7a from the unlocked movement position, the mechanical resistance of the resilient balls (pressure balls) 50 must be overcome. As a result, the handling of the handle 11 for the purpose of up and Zuschwenkens the sash 7a, in particular with the sash open 7a, secured.

After pivoting the sash, such as to replace an X-ray apparatus in the working space of the safety housing, the sash 7a is again applied to the main frame 9 (closed), and the sliding door 10a is from its unlocked position on the left-hand mechanical stop 49 back to the locked (fully closed ) Moved to the right-side auxiliary mechanical stop 49a. In this case, the latch 32 is taken, and this finally locked again the sash 7a on the main frame 9. In the fully closed position of the sliding door 10a, the actuator 31 jumps through the compression spring 45 back to the first position and thus in the sliding door mode.

The securing of the unlocked Verfahrstellung the sliding door in the folding door mode can alternatively or additionally not only more difficult, but also mechanically locked by a locking mechanism, as in the FIGS. 5a and 5b is illustrated. These show a perspective, approximately frontal view of a door mechanism according to the invention similar to that in FIG Fig. 4a-4c illustrated door mechanism. FIG. 5a shows a closed and locked sash while FIG. 5b showing a swiveled, unlocked sash.

In the sash frame 7a, an approximately cylindrical locking element 51 is provided, which is arranged in a recess 52a and extends through a bearing bush (guide bush) 52b. The bushing 52b is glued into the recess 52a or otherwise mechanically fastened (such as screwed in). The blocking element 51 is biased by a compression spring, not shown in the interior 53 of the locking element 51 in a position on the main frame 9 to outstanding position, in Fig. 5b you can see. In this position, the blocking element 51 blocks a method of the bolt 32; the bar 32 comes up with his in Fig. 5b left side of the blocking element 51 at. As a result, a method of hinged with the actuator and the driver to the latch 32 sliding door 10a in Fig. 5b to the left (locked position). The latch 32 is then fixed in the unlocked position; the shutter door 10a remains in an unlocked travel position on a (in Fig. 5b not shown) mechanical stop held.

If the sash is closed (ie applied to the main frame 9, cf. Fig. 5a ), the locking element 51 is pressed by a rigidly formed on the main frame 9 counter-locking means (guide pin) 54 in the recess 52 a. The locking element 51 is then no longer in the travel of the bolt 32. In the range of travel of the bolt 32 is then only a constriction 55 of the lock means 54, but of the in his End region approximately C-shaped latch 32 can be encompassed, so that the locking means 54 does not block the travel of the bolt 32. When the hinged door 7a is closed, the latch 32 can then be actuated by the sliding door 10a and in particular locked (ie in FIG Fig. 5a to the left). In Fig. 5a is the bolt in the locked position, wherein the left fork-like part of the bolt 32 is not shown for simplicity. The lock means 54 acts with its thickened, free end as a behind-hook for the latch 32 to fix the sash 7a on the main frame 9.

In summary, the present invention describes a security enclosure for an X-ray apparatus which releases hazardous X-rays, the access of which is provided with a door having a double frame system allowing both a pivoting function and a sliding function. This dual function allows space savings during normal operation of the X-ray apparatus, such as trial changes, before access. Both functions can be operated via a single actuating element via the sliding door, wherein a slight movement of the sliding door in a second position of the actuating element is used for actuating a bolt (or a bolt system with several individual bolts). This achieves a high degree of operating comfort and a simple structure. In particular, no external tools or tools are necessary for switching the functions. When the sliding door function is active, the hinged door function is mechanically locked, and the sliding door is mechanically locked when the hinged door function is active. The access can be secured with a single security module.
