Definitions

• Safety cabinet in particular hazardous materials cabinet
• the invention relates to a safety cabinet, in particular hazardous materials cabinet, for storing preferably liquid hazardous substances, with a cabinet body, also with at least one cabinet door, and with at least one locking element for the cabinet door.
• Safety cabinets and in particular hazardous substance cabinets are typically used to store and store liquid hazardous substances.
• the cabinet body is usually made of a fire-resistant material, so that a fire resistance of at least 30 minutes and especially of 60 minutes and more is guaranteed.
• the prior art may not be satisfactory in all aspects.
• the conventional solutions typically resort to a key to lock an associated lock on the cabinet door.
• the key can be lost and, on the other hand, the operator often "forgot” to actually lock the safety cabinet after completion of the work.
• the invention aims to provide a total remedy.
• the invention is based on the technical problem of further developing such a safety cabinet and in particular a hazardous substance cabinet so that a simplified locking mechanism is provided.
• a generic safety cabinet is within the scope of the invention characterized in that the locking element is transferred after taking its unlocked position, taking into account a preselected period of time and / or a preselectable time again in the locking position, so that even an open cabinet door at transfer in the closing position and automatically locked after the time period against the cabinet body.
• the cabinet door is normally in its locking position or the locking element for the cabinet door is located in this locking position, even and especially when the cabinet door is open relative to the cabinet body.
• This time period can be in the range of minutes, is usually, for example, 10 seconds, 20 seconds, etc.
• a transfer of the locking element can be linked to the locking position at a pre-selectable time. For example, it is conceivable to control the locking element so that this assumes its locking position every day at a certain time, for example at 17.00 clock, 18.00 clock, 19.00 clock, etc. and / or, for example, the locking position is maintained throughout the weekend.
• a control unit for acting on the locking element is provided.
• the control unit may be equipped with a timer and / or a clock.
• the capture of the unlocking position on the part of the locking element detected by the control unit and on the other hand with the help of the timer, the desired and preselected time duration can be specified and adhered to.
• an unlocking signal in the control unit which accompanies receipt of the unlocking position on the part of the locking element can ensure that the local clock is activated. With the help of the clock
• control unit can then, alternatively or in addition to the preselectable period of time, ensure that the locking element assumes its locking position at a specific and preselectable time or is transferred into the locking position.
• the control unit it is conceivable, for example, to generate a necessary unlocking signal in the control unit with the aid of an access code in the form of a secret number or pin number, which is transmitted via an input field or an access control unit of the control unit.
• the access code can also be transmitted via an access card, an access chip, on the basis of biometric data of an operator willing to access etc. of the control unit for checking. It has proven to be altogether good if the control unit has for this purpose the access control unit which checks the access code in question and previously described for plausibility and authorization.

• the taking of the unlocking position by the locking element is usually keyless, for example, by an operator enters his access code to the access control unit and this access code is considered permissible.
• the control module of the control unit then ensures that the locking element assumes its unlocking position.
• a timer is started as a further component of the control unit and thus set the preselected period of time in motion and / or fixes the preselectable time at which the control module of the control unit acts on the locking element such that this is transferred back into the locking position.
• a safety cabinet in the context of the invention, which is equipped with an optimized lock and a related significantly improved locking routine compared to previous safety cabinets.
• For the taking of the unlocking position on the part of the locking element for the cabinet door is designed to be temporary.

• the invention as a whole ensures that the cabinet door is equipped after a certain period of time or at any given time in each case with a locking element which assumes its locking position. If the cabinet door is then in an open state, the cabinet door is automatically locked against the cabinet body during the closing process. Elaborate locking measures, a key operation, etc. are expressly not required. This simplifies operation and significantly increases safety. Here are the main benefits.
• the locking element is generally assigned a guide slot.
• This guide slot ensures that the locking element properly assumes its locking position and unlocking position and can also take reproducible. This is particularly necessary against the background, as the locking element is advantageously acted upon by a spring.
• the locking element is a locking pin.
• the design is usually made so that the locking element occupies its unlocking position against the force of the spring in question and is transferred with the force of the spring in the locked position. That is, when taking the unlocked position, the spring is tensioned. If, on the other hand, the locking element is to be transferred into the locking position, then it is only necessary for the spring to relax and in this case take along the locking element or the locking pin which is usually realized at this point. In this way, malfunctions are avoided and at the same time the locking position is mechanically and functionally preferred.
• the locking element is typically arranged at the edge of the cabinet door. In most cases, the locking element is connected to the inside of the cabinet door. If several cabinet doors are realized, it is advisable to equip each individual cabinet door with at least one locking element. Of course, it is also possible to work with several locking elements per cabinet door.
• the locking element passes through an opening in the cabinet door in its locking position. In this way it is ensured that the locking element or the locking pin projects relative to the cabinet door in its locking position. This allows the locking element engage in its locking position and closed cabinet door in the already mentioned hollow bore in the cabinet body.
