Description

Scheduling device for dividing a drawer

The invention relates to a classification device for dividing a drawer or other compartment of an operational bearing means, such as a drawer cabinet or other storage cabinet, which is provided as an insert in a drawer and divides the storage volume of the drawer into partial volumes of the storage volume.

Especially in the field of industrial manufacturing often objects must be stored, which represent a high value. These may be tools, measuring means, components and the like, the value of which may easily represent a four or even five-figure euro amount. However, there is a tendency that such items are increasingly being stolen from stock items, such as storage cabinets, even from factories and factory premises whose access is limited to certain groups of people. As a result, companies incur considerable financial damage.

For this reason, tool cabinets have already been developed whose access is controlled by an access authorization system. This should be locked or released from a central location whole cabinets and individual drawers. As the drawers are usually subdivided with partitioning means and different in the individual compartments of the drawers

Storage goods with different access rights may be present, for example, offered by the company SupplyPro Inc., framework, whose

Size corresponds exactly to the respective drawer surface. The frame should be placed on top of the drawer and fastened to it. It has a matrix-like structure and has for each compartment of the respective drawer a top accessible and closable with a hinged flap and releasable opening. Each flap has a release request button associated with it on the frame, which is used by a parent access release device to release the message

Opening the specific flap requested or a flap can be opened. Depending on the stored in the access authorization scheme on the entitlement of individual users to access individual subjects, then the locking device of the corresponding flap is unlocked or maintained the lock.

However, such operational bearing means may not be satisfied that they are relatively rigid and inflexible with respect to changing bearing requirements. The invention is therefore based on the object by suitable measures, the division of a drawer - despite a way to predetermine access to certain subjects of the drawer - to change without much effort.

This object is achieved according to the invention in a classification device of the type mentioned by the features specified in claim 1, which provide in the plate arranged on the classification closing device with one or more sub-volumes whose sum is smaller than the storage volume of the respective drawer for an access is releasable or lockable .. The object is further achieved by the subject-matter of claims 10 or 11.

The invention thus proposes to provide a smaller structural unit of the locking device, which detects only a portion of the (full) storage volume of a drawer instead of a one-piece frame for the entire drawer. In a first variant, the closing device may have a structural unit as a frame, on which one or more closing means are arranged, wherein the frame covers only a portion of the drawer. The remaining other portion of the drawer can either remain free or this other portion is at least a second closing device or classification means associated, which also has one or more separately and independently operable closing means.

In another preferred embodiment of the invention, a locking device is also provided, which - unlike previously - not the complete Drawer detected, in which case at least one of the closing means with one of the dividing means structurally, ie objectively, should be connected, with a subdivision of the storage volume of the respective drawer is made in one or more sub-volumes. At least one closing means should be arranged on the closing device, which can be unlocked or locked for accessing or closing one of the sub-volumes on the basis of an enabling signal for the at least one sub-volume and independently of other sub-volumes. In both solutions can be provided, by supplementing with other identical or other locking devices control the access options on the storage volume of the entire drawer bwz. to pretend.

Since in the inventively provided solutions, the closing means are not arranged on a one-piece frame covering the entire drawer, with significantly less effort than before a change in the division of the respective drawer is possible. For an adaptation, it is not necessary to replace the responsible for the entire drawer locking device. It is sufficient and only possible with the invention to adapt only partial areas of the storage volume to changed storage conditions with the closing device. For the first time, it is even possible to provide only portions of a drawer with a locking device with which access can be released or denied. The then remaining other portion of the drawer may be provided for the storage of stored goods that requires no access restriction.

In a preferred embodiment, the closing device can be connected to or attached to partitioning means with which partial volumes are delimited from one another. Such partitioning means may be, in particular in a drawer, substantially vertically oriented dividing walls. In such expedient embodiments of the invention, the drawer bottom can be provided as a lower boundary of the partial volumes. It is particularly preferred if such partitioning means are designed as boxes or can be assembled as boxes, which serve as an insert in a drawer are provided, and on one or more boxes a closing device is arranged. In alternative embodiments, the form of a closable box or a container can only be due to the inclusion of side walls or the bottom wall of a drawer.

In an expedient development, a plurality of boxes can be combined to form an assembly of boxes, in particular to a line next to or behind one another arranged row of detachably or permanently connected boxes. The box line may have a length corresponding to the width or the depth of the respective drawer and are secured with advantage on side walls of the drawer or at the bottom against removal. Each of the boxes can be associated with a single operable and lockable flap, wherein at least two, preferably all, flaps of the box members can be pivotally connected to a common pivot axis.

In order to achieve a particularly good adaptability of the division of the drawers to the particular storage requirements given should, in a preferred embodiment of the invention dividing means, in particular boxes, can be provided with which different sized sub-volumes of the storage volume of a drawer form or delimit each other. At least one, preferably several or all of these sub-volumes should be provided with a closing means, which is adapted with respect to its size with advantage to the respective sub-volume. In particular, when each of the closing means is attached only to a box or dividing means, a particularly good variability of the subdivision of the drawer results, while at the same time good controllability of the access possibilities to the individual partial volumes. Partitioning and closing devices according to the invention should be exchangeable and as freely as possible interchangeable with as little effort as possible against other partitioning and closing devices.

Further preferred embodiments of the invention will become apparent from the claims, the description and the drawings. The invention will be explained in more detail with reference to embodiments shown purely schematically in the figures, in which:

Fig. 5 parts of the locking device in an exploded view.

The drawer 1 shown in Fig. 1 belongs to a drawer cabinet (not shown), which in turn is combined to form a group of drawer cabinets, which are assigned to an access authorization device (not shown). Each drawer cabinet has a plurality of drawers 1 extendable from the body of the respective cabinet.

The access authorization device has a computer, not shown, which is connected via data lines to each of the drawer cabinets. With a program product (software) which is already known per se, the cabinets and individual drawers can be released or blocked for access by certain persons and / or groups of persons. The blocking or release takes place via individually or jointly addressable mechanical closing means of the drawers. Such access authorization devices and drawer cabinets are already known per se _* In the known prior art drawer 1 shown in FIG. 1, several arrangement devices are used. The three partitioning devices designed as (box) inserts 2, 3, 4 together divide the entire storage volume of the drawer into separate partial volumes. The storage volume of the drawer 1 results from the surface of the rectangular bottom plate of the drawer and the height of its side walls. Of the three box inserts, FIG. 2 shows a box insert 3, 4 constructed by way of example for the basically structurally identical manner. As can be seen in conjunction with FIG. 1, the box inserts have the same length L, the length L of the box inserts corresponding to the width B of the drawer. In other embodiments, the length of the box inserts may also be smaller than the drawer width or depth. With respect to the depth T of the three pit inserts, these differ from each other, the addition of the depth of the pit inserts corresponds to the depth of the drawer.

Each box insert 2, 3, 4 has a cuboid box shell 7 with the length L. The pit shell 7 can be made for example of a metallic sheet by bending. In the area of its upper front edge, the pit shell is provided with an L-shaped bend 8. In their horizontal legs of the bend a plurality of recesses 9 are introduced at a distance, are fastened in the following even closer explained locking modules 10 by snap connections. The pit inserts can be hooked with their L-shaped bends 8 in the respective front of them arranged pit insert.

The two parallel aligned, the depth of the pit shell determining vertical side walls 7a, 7b are provided with a plurality of vertical slots 12, which are distributed uniformly over the length of the pit shell 7 in the embodiment. In the slots 7 separating plates 13 are arranged, which engage with formed on side edges of the separating plates tongues 13 a in the slots 12. The box shell 7 and the separating plates 13 thus form a total of four identical large boxes 14, each with a partial volume of the storage volume of Drawer. The boxes 15 of the other pit shells have different sizes.

An access to the boxes 14 can be prevented or released by closing means 17 belonging to a closing device, wherein in each case a closing flap 17 is assigned to a box 14 in each case. The closing flaps 17 are each formed in the embodiment as a flat sheet metal component, which covers the top of each box 14 substantially completely. At opposite side edges, each closing flap has a tab 17a produced by a respective vertical bend. Each of these tabs 17a is provided in the region of the rear side edge of the closing flaps with a round recess 17b, through which a pivot shaft 18 is guided. The closing flaps 17 can perform pivotal movements about the pivot shaft 18 to the opening of the respective box on the content thereof, regardless of the respective other closing flaps 17 of the same pivot shaft 18. The ends of the pivot shaft 18 may be secured in the side walls 5 of the drawer, resulting in a Assurance against unauthorized removal of the respective box shell 7 results from the drawer. The closing flaps are thus inextricably linked with their respective assigned box, which is to be understood by "unsolvable" such a connection that can be resolved at most with a suitable tool and / or by using force.

Each of the closing flaps 17 has a recess in the region of its front side edge into which a handle shell 20 designed as a plastic injection-molded part is inserted (FIGS. 3, 4 and 5). Due to a snap connection, the handle shell can be secured in the closing flap so that the handle shell can be removed only with the open flap 17 and only with the aid of a tool from the flap. Each grip 20 has a recessed grip 21, as well as a slotted locking hook 22. Below the slot 22a, a small permanent magnet 23 is arranged in the hook. Each locking hook 22 cooperates with a respective locking module 10, which is arranged in each case one of the recesses 9. The closing modules 10 shown in FIGS. 3 to 5 have a carrier 25, which is provided on the upper side with a membrane keyboard and two LED lights 27. Under the carrier 25, a latch 29 is disposed at one end of a locking bar 28. At the other end of the locking bar 28 is an armature 30 of an electromagnet. Finally, located in the region of the permanent magnet 23, a circuit board 31st

All locking modules 10 are connected via a computing unit of the respective drawer cabinet or in alternative embodiments directly to a higher level access authorization device. The connection can be made via data lines or wireless data connections. The access authorization device may provide a way to group cabinets, drawers 1 and / or boxes 14, 15 into one or more lock groups that may be accessed by one or more predetermined persons.

In order to be able to access a particular drawer 1, a user in the preferred exemplary embodiment must log in to the access authorization device and specify there which stored goods, for example a specific tool, he wishes to remove. The access authorization device determines on the basis of a

Database, a kind of inventory list, and a list of people and theirs

Access authorizations, in which drawer cabinet (operating storage means), which drawer and in which box 14, 15 is the tool and whether the respective

Person owns an authorization for the removal of the respective object, here a specific tool.

If the access authorization device, on the basis of the data available to it, comes to the conclusion that this person has authorization to remove the tool, the access authorization device then signals this by illuminating a respective light on the corresponding drawer and a light 27 to the corresponding box 14 where the tool is sought. In addition, the access authorization device releases the corresponding box 14 for unlocking. For removal then the user has to press a release button of the membrane keypad 26 at the corresponding box 14, whereby the electromagnet is energized and pulls the previously arranged outside the armature 30 in the electromagnet. The movement takes place against the force of a spring, which would like to press the locking bar 28 and the latch 29 into the locking position in the slot 22a. By the electromagnet, the latch 29 is moved out of the slot 22a of the locking hook 22, whereby the closing flap 17 is released for opening.

By connected to an opening of the closing flap removal of the permanent magnet 23 from the board 31, a signal is generated in this or set a previously existing signal to zero, which in turn causes the electromagnet is de-energized. The armature 30 thereby moves back out of the electromagnet, whereby the latch 29 assumes its original position. When closing the flap 17 then presses the hook 22 in its closing movement against an inclined surface 29a of the bolt 29, whereby this is pushed back against the force of the spring. However, as soon as the slot 22a is located in front of the latch 29, the spring force causes an opposite sliding movement of the bolt 29 into the slot 22a, whereby the respective box 14 is locked again.

In a not shown embodiment of the preferred embodiment of the invention shown in the figures, each memory flap and thus each box can be assigned its own microprocessor. It is also possible that a group of memory keys and thus a group of boxes each have their own microprocessor is assigned. The thus preferably more than one microprocessor per drawer may contain volatile or non-volatile storage means with which receive status information about the closing means, in particular the opening and closing and / or information on stored goods and / or environmental conditions, prepare and forward to a higher-level control to let. Such information may be, for example, the ambient temperature, humidity, weight of the stored goods, times of opening and closing of the storage doors, etc. In order to determine this information, suitable detection means known per se can be provided.

It can also be provided that in a (temporary) failure of the parent control of the drawer cabinet or one of these parent access authorization device, all of the information or parts thereof written to nonvolatile memory means of the microprocessors and there until retrieved by the controller or the access authorization device get saved. It is thus also possible to determine other information generated by the access authorization device itself and to document it even in the event of a failure of the access authorization device.
