Abstract

Method and means for ensuring a sealing of openings to otherwise mainly closed chambers closable by gates or doors, with a sealing arranged in a groove around said respective openings, and preferably the sealing of slidable autoclave doors. After closing the door the sealing is put under the influence of the force of a pressurized medium, which force is greater than needed for achieving a satisfactory seal, so that the sealing is pressed against a sealing surface, whereafter a mechanical locking means located behind the sealing is brought into a locking position, in which the locking means supports the sealing when the force from the pressurized medium is released and the sealing is pressed against its sealing surface with a predetermined force by the mechanical locking means.

Description

METHOD AND MEANS FOR LOCKING AND SEALING OF A DOOR
The present invention relates to a method for ensuring a complete sealing of doors, preferably sliding doors for autoclaves. The invention also relates to an arrangement for carrying out the method.
In order to close and seal openings for autoclaves some kind of door is required, and since autoclaves of the type used today, in recent years have developed in a direc¬ tion which means that such doors usually are sliding doors, sealings of conventional kind are not possible to use, as is the case with pivoting doors where a passive sealing may be arranged between the door and the door frame. Con- sequently, use is made of sealings, which are activated first after the door has been slid into position and has been locked with elements suitable for the purpose, and preferably are kept in position by a pressurized medium, for example air. However, this means that one has to constantly rely on permanent access to the actual pressur¬ ized medium in case a minor leak arises in the active system, the purpose of which is to keep the sealing in a correct position. The use of autoclaves as a method for reduding the risk for infection and contamination is well known and established both in industry, medical care and of course in research and development in laboratories . In laboratory environments so called risk autoclaving is frequently used. This may be conventional sterilization, but the issue may also well be to ensure that the objects put in the autoclave when again taken out therefrom, really have reached the intended condition, as for example elimination of genetically manipulated organisms, which under no circumstances may be allowed to leave the auto¬ clave. For such purposes gas autoclaving may for example be suitable. When mortally toxic gases hereby are used during the autoclaving process, it is of even greater importance that the best possible sealing of the opening to the aut¬ oclave cabinet may be guaranteed. At autoclaving with an autoclave having a sealing of the above mentioned kind, the security is not the best possible, since the sealing constantly has to be connected to a system with pressurized media and since if for example the sealing pressure during an autoclaving programme under progress should be lost, it is most difficult to reverse the process. There is con¬ sequently a considerable risk that dangerous substances will leak through the opening of the autoclave. This is of course not satisfactory.
The main purpose of the invention is consequently to accopmlish a method for achieving a completely safe sealing during an autoclaving process, which is not dependent of outer prerequisites such as availability of oil/gas pressure, electricity, pressurized air, etc. in order to be kept in a sealing position. At the same time this should be achieved without having to connect elements such as motors, shafts, gear wheels or gears, to the outside of the construction in connection with the autoclave opening, which should be kept as clean as possible.
Another object of the invention is to achieve a method eliminating the need for the sealing to be constantly pressurized during an autoclaving process. Still another object with the invention is to achieve an arrangement to realize the above mentioned method.
With a method and an arrangement according to the invention, a sealing is accomplished which regarding safety is at least as good as a sealing of the initially mentioned kind with doors hanging on pivots is. Moreover, the particular advantage is obtained that the door, which is sealed and locked in the said way, cannot be opened until active measures have been taken in order to deactivate the sealing and unlock it. According to the invention the door sealing, after closing the door, by means of the force of a pressurized medium, which force is larger than required, is brought into a tight contact with its sealing surface in order to achieve a satisfactory sealing, and that mechanical locking means, situated behind the sealing, thereafter is brought into a locking position in which the locking means supports the sealing when the force from the pressurized medium is released, whereby the sealing is kept pressed with a pre- determined force against the sealing surface by the mechanical locking means.
In the following the invention will be described more in detail with reference to the accompanying drawings showing preferred embodiments which are not delimiting to the invention, where:
Fig. 1 shows a front view of an autoclave with its door open,
Fig. 2 shows a front view of the same autoclave after closing the door, Fig. 2A shows a section along the line IIA-IIA in Fig 2,
Fig. 2B shows a view along the line IIB-IIB in Fig 2,
Fig. 3 shows a partial section along the line III-III in Fig. 1 through a sealing for an autoclave door with its locking in an open condition,
Fig. 3A shows a section along the line IIIA-IIIA in Fig. 3,
Fig. 4 shows a section corresponding to the section according to Fig. 3, where, however, the locking is active, Fig. 4A shows a section along the line IVA-IVA in Fig. 4, and
Fig. 5 shows a section along the line V-V in Fig. 4A.
With reference to Fig. 1 an autoclave cabinet 1 is shown from. its front side with a door 2, which is intended for closing the chamber K of the autoclave, and is in an open condition. The door 2 is of the sliding kind and is supported by a guide 3 via two ball bushings 4 in such a way, that it has its gravity centre right below the line of transfer. Thereby the door becomes especially easy to slide in an unlocked condition. Since the door is relatively heavy although it is easy to push, the linear momentum imparted to it during its movement becomes relatively large. It is therefore preferred that the door is handled with a motor giving driving or braking torque according to demand, the motor however not being shown. From the drawing it also appears that the autoclave comprises levelling screws 5, which are intended to enable a completely horizontal position for the autoclave. It is further shown that the door 2 and the respective front edge 6 on the side walls of the autoclave, in an alternative embodiment may have sturdy engagement means 7, which are complementary to each other and will be discussed more closely in connection with the description of Figs. 2A and 2B. Last but not least, it appears that a groove 8 containing a sealing 9 is arranged around the front edge 6 of the autoclave cabinet 1 and that locking means are arranged behind the sealing.
In Fig. 2 is a view analogous to Fig. 1 with the difference that the door 2 has been pushed to its closed position and been locked. In order to clarify how the locking forces from the door 2 are recieved by the auto¬ clave cabinet 1 when loaded by the door sealing, which is the consequence of the locking, a section along the line IIA-IIA is shown in Fig. 2A. In this figure it is clearly shown that hooks 7a on the door 2 engage a groove 7b that has been milled out of the autoclave. In a corresponding way Fig. 2B being a view from IIB-IIB in Fig. 2, shows how regular engagement hooks 10 engage a flange 11 on the edge of the cabinet .
Fig. 3 and 4 show sections III-III from Fig. 1 and IV-IV from Fig. 2, respectively. The section in Fig. 3 thereby shows two rows 12a, 12b of ramp elements 13 , which are intended for engagement with each other and together establish a locking arrangement 12, and also how the last mentioned arrangement is contained in the groove 8. The locking is achieved in that one of the two element rows 12a, 12b, separated from each other, namely row 12a, is forcedly translated a distance relative to the other row 12b that approximately equals half a partition between the complementary ramp elements 13 to the elements in the element rows 12a, 12b. As shown a frame 14 is located outside the elements 13 and is fixed to the element row 12b. Outside the frame 14 the sealing 9 is arranged in the groove 8. In order to clarify the function a section along the line IIIA-IIIA in Fig. 3 is shown in Fig. 3A. In addition to the earlier mentioned details 8, 9, 12 and 14a, a connection 15 is also shown in Fig. 3A, which is meant to be connected to supra-atmospheric and sub- atmospheric pressure respectively. At the application of supra-atmospheric pressure, the sealing is pressed in a direction out of the groove 8 and is pressed against the sealing surface around the edge of the door 2. Cooperation between the flanges 11 and the hooks 12 or between the hooks 7a och 7b in the alternative embodiment, hereby constitutes the reaction means that makes it possible to compress the sealing against said sealing surface.
As shown in Fig. 4 by the application of the suplra- atmospheric pressure behind the sealing 9 the latter is thereby compressed to such an extent, that the frame 14 allows a forced translation of the element row 12a in the groove 8, so that the plateau surfaces on the elements in the element rows 12a, 12b will be positioned in front of each other. When the element rows have assumed this posi¬ tion, the sealing 9 is released from the supra-atmospheric pressure, whereby a sealing of the door 2 with a pre- determined prestress is achieved. For elucidating purposes Fig. 4A shows a section along the line IVA-IVA in Fig. 4. From this figure it is evident how the sealing 9 is pressed against the door 2 after the release of the overpressure. By this thrust force and friction between the plateau surfaces 12c a completely safe locking as well as a sealing of the door 2 is achieved. Fig. 4A also shows the connec¬ tion 15 for the supra-atmospheric and sub-atmospheric pressures, said pressures, depending on the situation, being supposed to be applied during manoeuvering of the locking, either for locking or unlocking the door 2. In order to avoid that the sealing 9 is brought away during the sliding movement after unlocking and thereafter sliding of the door 2, a sub-atmospheric pressure is applied to the connection 15 at the rear side of the sealing. This means that the sealing is sucked into and is completely contained in the groove 8 whereby it cannot be damaged.
Fig. 5 finally more in detail as a partial view from the front side of the cabinet shows how the element row 12a is arranged. Fig. 5 shows the row 12a after being exposed, i.e. after dismantling the sealing 9 and the frame 14, respectively, together with the associated ramp element row 12b. The element row 12a is almost to be seen as a combina¬ tion of "rack gears" and "chains". The reason for the use of the word "rack gears" is that the ramp element row 12a along the straight portions of the groove 8 comprises integrated portions, which like a rack gear contains re- petedely reoccuring configurations, in the present case ramp elements with associated plateau surfaces. With the generic form "chains" is meant the parts of the ramp element rows that are contained in the turns 16 of the sealing groove 8. The individual ramp elements are here connected to each other in the same way as conventional chains in order to allow a translational movement along the curves of the groove 8. In the shown embodiment said movement is achieved by a rotational movement from a motor (not shown) , which acts on a shaft 17 on which a gear segment in the form of a circle sector is fitted, and which upon rotation of the shaft 17 by the motor acts on a rack gear 19, that is contained as a part between the "chains" and "rack gears" of the ramp element rows 12a. The gear segment 18 engages the rack gear 19 through a slit 20 in the outer wall of the groove 8. Therefore, it is necessary that the gear housing 21 that surrounds said gear is sealed in relation to the outside of the autoclave in order to enable a pressurization of the space behind the sealing 9 with supra-atmospheric or sub-atmospheric pressure when manouvering the locking means.
It should be understood that the description above only covers an embodiment of the present invention and that the invention therefore in no way should be delimited thereby, but shall comprise also other embodiments covered by the appended claims .
