Description

20 25 30 35 532 383 The problem that is the basis for the present invention is taken from the above situation, but the person skilled in the art realizes that the access control system can be used for other purposes where there is a need for åt your access levels.

Summary The locking mechanism that Phoniro AB uses needed to be modified to fit the lock that is in the most common medicine cabinets. As medicine cabinets today use locks other than exterior doors, a different type of locking mechanism needs to be developed. To achieve the objectives mentioned above and below, an access control system according to claim 1 is provided. The subclaims state preferred embodiments.

Detailed description Without mutual order, there are some wishes about how the access system should work in a medicine cabinet: Requirements and wishes - Increase the security of medicine cabinets - Reduce the need for key use in the home care service 10 15 20 25 30 35 532 353 - The cabinet must be mountable - Must be accommodated in a wardrobe - It must be possible to unlock it with a key - The cabinet must hold Dosett®, ApoDos and medicine jars.

- Affordable, as the mechanism today is expensive.

- Must be able to be unlocked without a key in the lock.

- The technology should be easy to understand for all users.

- Make access difficult for unauthorized persons.

- Reduce the locking mechanism, as today's is too thick to fit a medicine cabinet.

- The lock must have control of the medication.

- It must be easy to maintain / repair the locking mechanism and change the battery Of these, increasing the safety of the cabinets is a main requirement as today's medicine cabinets do not offer solutions that are sufficient for the control needed. Reduced use of keys is the group's other main requirement as they not only make it easier for the staff involved but are also time-saving, the nurses avoid the search for keys. Nature also feels better if the nurses do not have to drive a car to pick up keys. Other requirements listed above are not necessary but desirable for the use of the product and to get the best end product possible. The list of requirements has formed the basis for product development during the project.

An additional wish is to achieve a removable locking module, this turned out to be a difficult task during the project as all medicine cabinets look different and there are no standard cabinets. Therefore, due to too short a project time, the group has chosen to focus on a locking module that must be movable on the cabinets that have a handle with the standard distance of 128 mm. This is of course not a limitation on the invention as such, but only the specific prototype that was manufactured.

LOCK TYPES Haslås - see fi g. 1 Hasl lock is the type of lock that is most common in today's medicine cabinets. With that in mind, the group, with the help of brainstorming, came up with a proposal that can be used on both single and double cabinets. All components needed for turning the lock, ie the motor, batteries, circuit board and gears, will be built into a box similar to a VHS tape, to maximize the space in the medicine cabinet. The box which is located on the inside of the door and is connected to the locking reel makes it possible to turn the reel according to the set desired number of degrees, the number of degrees varies depending on the type of cabinet it is. The difference between the single and double cabinets is that there is a top in the cabinet that divides it into two parts. The board not only has a compartmental function but also makes it possible to limit the supply in the cabinet depending on what authorization you have.

The partition wall will act as a frame where the hasp goes through a crack and fastens in the other door, which means that both doors are locked. The idea behind this is that if you only open the lock 45 degrees, only one of the doors will open because the hasp is still in the compartment frame, if you open 90 degrees, both doors will open and you have access to the entire cabinet.

Advantages - Hasl lock available in different lengths - No new components need to be developed - Most medicine cabinets have hasl locks so you do not have to make too large an intervention in the cabinet.

Disadvantages - Key must be in the lock to be able to lock - Mechanical problems Lock lock - see fi g. 2 The other solution we came up with was a sliding lock that is best suited for double cabinets but can also be modified for single cabinets. Here, too, the idea is to build a box that includes all parts and is placed on the inside of one door. Instead of having a hasp, the idea here is to use a locking bar that is toothed on one side.

The reason for this is that the motor sits against the teeth and moves the locking bar back and forth through the gap in the partition.

Advantages - A more robust construction - Relatively easy to solve mechanically Disadvantages - Must change gears on the motor to a straight cylindrical as the current is conical! Program the number of revolutions the motor should spin. 10 15 20 25 35 532 353 Click lock - see fi g. 3 This solution is based on a small pin that is connected to an oval part that is attached to the engine head. The engine used for this solution works differently from the other solutions. It locks sideways instead of rotating. The motor with the pin is placed on the short side of the cabinet so that the hasp goes over the pin, which means that the lock is disengaged. When someone activates it with the help of the phone, the pin slides easily and smoothly under the hasp. This solution only works on cabinets with a single door.

Advantages - The lock does not need to be unscrewed - Relatively easy to solve mechanically Disadvantages - Works only on a cabinet with a single door - The choice of material on the pin. Must be both strong and soft.

DISCONNECTION MECHANISM Half-geared gear - see fi g. 4 This proposal is based on the use of the reel lock mechanism where the reel is replaced with a completely new part, which looks like a gear that is geared on one half of the wheel. The reason why it is toothed at the top is to be able to open the cabinet with a key if needed, for example when the batteries have run out in the locking unit. The teeth engage with mating teeth in a rule (see fi g. 4), preferably a locking rule or other rule operatively connected to the locking rule.

Locking piston with sprint ~ see fi g. 5 This proposal is based on having a threaded inside of the locking piston, when the key is inserted into the lock and turned, a piece of the inner casing in the locking piston is moved out (A to B). This causes the inner casing to act as a pin, which in turn attaches to a tooth (D) and causes the tooth to spin. When unlocking, the key is turned back, the inside cover and the pin then release the tooth and the lock can then continue to be used as a disengaged lock.

SELECTED SOLUTION Locking mechanism After evaluation and with the help of the evaluation matrix, the group decided to proceed with the sliding lock. This was chosen despite the fact that an evaluation matrix showed that the reel lock had advantages due to the fact that it was easier to solve mechanically. No consideration 10 l5 20 25 30 35 532 383 need to make sure that the key must be in the lock for it to be possible to lock. What also spoke for the sliding lock is that it has greater potential to include your functions. An example of a function is to place the locking mechanism on a double cabinet, which can then regulate the users' access.

Disengagement After the group's choice of solution proposal for a locking mechanism, the half-geared gear was chosen as the solution to the disengagement problem. The advantage of this is that the effect on the lock is small, as you only screw on an extra part at the far end of the locking tube. Which is an important aspect when the lock is to be made fl obvious, which was one of the requirements. Se fi g. 8 showing locking tube and half-toothed gear with locking kit. The half-geared gear 20 makes the lock operable with the motor while a seated key is not rotated.

The other parts of the locking kit are obvious to the specialist arm.

Choice of material The box where the electronics are arranged is made of the same plastic Phoniro has used in previous locks, ie PA6 with 30% glass. The gear rack (which in the embodiment shown also constitutes the locking bolt), the gear wheel and the semi-geared gear wheel will be made of hardened automatic steel. The locking straps will be made of hot-dip galvanized sheet steel, DX5 l + Zi00. The cabinet can be made of chipboard or sheet metal depending on the customer's wishes. Those skilled in the art should realize that the invention is not limited to precisely these material alternatives, but other alternatives are possible within the invention framework as defined by the appended claims.

The invention has resulted in a locking mechanism and a medicine cabinet that offers a keyless alternative and a function for controlling medication. To gain access to the medicine cabinet, a mobile phone with an authorization key is programmed.

The basic technique for this is, as previously mentioned, described in previous patent applications by the present applicant. To activate the lock controlled by Bluetooth technology, a light tap on the cabinet is required. The product offers different access depending on the person's qualifications, for example the nurses have access to both cabinets while the assistant nurses only have access to the part where ApoDos and / or Dosett® are stored. This function has taken into account your hospital regulations, as the assistant nurse may not have access to medicine jars.

The product is made up of three main parts with different properties that are built into a box l0 and is described with reference to fi g. 6 and 7. The drawer is screwed 10 15 20 25 30 532 383 on the inside of one of the doors of the medicine cabinet (not shown). To fasten the box 10, the same screws are used that hold the handle in place. It is thus part of the character of the invention that it is preferably retrofitted without major, if any, impact on the cabinet.

The selected handle has a standard distance of 128 mm between the screws. A motor 12 is placed in the box, the task of which is to move the locking bolt 14 from the open to the locked position.

The motor 12 is connected to a circuit board 16 (control unit) which is pre-programmed to move the locking bar 14 a specified number of motor revolutions, depending on which authority the telephone is programmed for. The circuit board 16 and the motor 12 are connected to two lithium batteries of 3.6 volts each (arranged in the compartments inside the battery cover 18). A microswitch (not shown) is located below the locking latch 14 to register when the latch is in the home position, i.e. when the cabinet is fully open. The reason for this is that the circuit board 16 must register that the part in the cabinet where the medicine jars stand has been opened.

This means that a log can be kept over the opening and closing of the cabinet. When the cabinet is opened with Bluetooth technology, this is registered in the log, and if the microswitch is activated by opening the lock with a key, this is also registered. In the former case, it is also registered who opened the cabinet (ie, which telephone is used) and in the latter case it is registered that the cabinet was opened with a key. This prevents anyone from opening the cabinet with a key and accessing the strong medicines unnoticed. All electronics are built into the box to prevent lay people from coming into contact with it. When unlocked with a key, it causes the half-geared gear 20 to rotate and cooperate with the gear 22 located on the top of the locking bar, while the gear 24 arranged on the motor shaft cooperates with the gear 26. The half-geared gear 20 also allows operation of the lock by means of the half-geared gear 20 - and thus components connected thereto - are affected.

Figs. 11a and b show an embodiment of a cabinet according to an embodiment of the present invention. The cabinet is shown from above, and it is easily understood how it is possible to unlock one door (on the right in the picture) by moving the bar 14 a first distance, so as to be pulled out of a shackle fitting 40 arranged on the said one door. To keep the second door (left in the picture) locked when the locking bolt is in this position, for example, a center post can be arranged in the cabinet, between the doors. By moving the locking bolt another bit, it disengages from the center post, whereby the other door can also be opened. The center post can also consist of a structural section (partition wall) that separates the two spaces. Fig. 7 is a photograph of a locking system according to an embodiment of the present invention, and apart from the orientation of the batteries, the design is recognizable from Fig. 6. Note the microswitch 28.

Note that the inventive system is also trained for use in access-controlled systems with more than two access levels. A very simple adaptation of the described system is to let the locking bolt be movable for a longer distance, over two or fl your doors.

ALTERNATIVE SOLUTION SUGGESTIONS Solution suggestions I -fi g In Hasplås is the most common lock on medicine cabinets and it felt natural to try to find solutions. It involves attaching a gear around the locking tube, on the inside of the lock, which is turned by a motor with a geared gear. The hasp is attached to the gear, which will then move the hasp from locked to open position (90 degrees).

Solution proposal 2- fi g. 2 The sliding lock means that instead of a hasp, you have a boom or locking bolt that is moved back and forth through a hook, which in turn holds the boom in the other door or on the side of the cabinet. The motor then moves the boom back and forth from open to locked position.

Solution 3 -fi g 3 This solution is based on a small pin connected to an oval part attached to the engine head. The engine used for this solution works in a different way than the other solutions. It locks sideways instead of rotating. The motor with the pin is placed on the short side of the cabinet so that the hasp goes over the pin, which means that the lock is disengaged.

Solution proposal 4 -fig 9 A simpler modification of the current locking module so that it fits on a lock that is similar to those that usually sit on today's garage doors. Where there is a locking bar that goes out on each side, this provides a robust and very secure construction. 532 353 Proposed solution 5 -fi g. 10 A solution based on Phoniro's key cylinder. Around the locking reel is a ring with a notch. When the reel is in the locked position, the pin holds the reel, when unlocking, pull the pin back and the reel can be turned.
