Definitions

  • Such a security housing has been used for example in the commercially marketed X-ray spectrometer "D5000” Bruker AXS GmbH, Düsseldorf.
  • 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.
  • X-rays are 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.
  • radiopaque safety housings protecting housings
  • the safety housing is closed.
  • the safety housing must be opened for a sample change.
  • hinged doors Very common are hinged doors.
  • 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
  • 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.
  • 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.
  • 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").
  • 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.
  • 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.
  • 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.
  • the safety housing 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.
  • 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.
  • 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.
  • the sliding door opens up as much of the access as possible without requiring additional space in front of the access.
  • 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.
  • 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.
  • a combined operation of sash and sliding door with the same handle and actuator easier by hand.
  • 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.
  • 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.
  • 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.
  • the actuator 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • the locking mechanism comprises a resilient ball in the sash, which engages in a recess on the bolt.
  • a resistance to sliding door procedures is established; This is very easy to realize.
  • 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.
  • 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.
  • 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.
  • the guide can be easily realized mechanically.
  • the expansion is typically at one end of the slot.
  • 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.
  • 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.
  • 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.

  • 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.
  • 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.
  • the axis S is vertical and the direction V is horizontal.
