Description

Servicebox for elevator systems

The invention relates to a service box for an elevator installation. Certain controls of functions of an elevator installation are located in a protected area, which should be accessible only to authorized persons. These include, for example, operating elements of the revision control, the lifting box or the fire brigade function. These controls are usually arranged in a box with a locked door, therefore, the term "hidden box" for such box is common. The door can usually only be opened with a key or an electronic signaler.

Other controls of functions of an elevator installation are arranged in a protected area which is to be accessible to all passengers. A telephone box, for example, can be designed as a box which can be closed by a door. However, telephone boxes should be accessible to all passengers unlike liftier boxes, revision controls or fire service boxes.

EP 1 967 477 A1 describes an emergency device for installation in an elevator car of an elevator installation. Such emergency devices for accommodating certain functions typically have a swing gate. Usually a hinge is arranged laterally, so that the door can be opened to the left or to the right. The hinges may also be located at the bottom or top edge of the box so that the door can be opened up or down. In both cases, the door swings into the room, for example, in the passenger compartment of a

Elevator cabin, out. As a result, such doors take up much space. In addition, open swing doors pose a risk of injury, and they can be easily pushed off and thus damaged. Swing doors also have the disadvantage that the setting of the door columns is difficult, due to the often high weight of such swing doors.

The object of the invention is to provide an improved service box for elevator systems, which does not have the disadvantages of the previous swing doors. To solve this problem, a service box for an elevator installation is proposed. The service box comprises a box-shaped base element. The service box further comprises a door, which lies in a closed state in a first level. The service box further comprises at least one lifting device, which is connected to the box-shaped base element and to the door, and by means of which the door can be transferred from the first level to a second level, wherein the first and the second level are substantially parallel to one another. The door can be moved to open the service box in the second level. As a result, the door can be moved over a surface adjacent to the service box so that the door never protrudes further than the second level into the room.

Further details and advantages of the invention will be described below with reference to embodiments and with reference to the drawings. Show it:

A box-shaped base element 6 with side walls 7 forms an open space, which can be closed by the door 3. In Figure 2, the base member 6 is partially open, so that an interior of the base member 6 is visible. The base member 6 is cuboid in the embodiment shown. The side walls 7 are preferably arranged so that they form a rectangle in an installed state viewed from a cabin inside, with two opposing side walls 7 extending parallel to each other. It is understood that the shape of the base element 6 can also have other shapes. In an exemplary alternative embodiment, not shown, the base element 6 is cylindrical with an oval base. In the embodiment shown, the door 3 is designed so that it is able to close an opening of the box-shaped base element 6. In the illustrated embodiment, the door 3 is rectangular to the cuboid box-shaped

Cover element 6 can. The door has two opposing guide elements which can be guided in rails 4, 4 '. These guide elements preferably run parallel to one another. In the embodiment shown in Figure 2, the door edges 5, 5 'form this

Guide elements, which in the rails 4, 4 'are feasible. However, other guide elements may also be formed on the door 3, which can be guided in the rails 4, 4 '. In an embodiment not shown, the door 3 at a

Lower guide elements, which engage instead of the door edges 5, 5 'in the rails 4, 4'. In this embodiment, the rails 4, 4 'are concealed, and it is also possible to use doors 3 which have no parallel door edges 5, 5', for example oval-shaped doors.

The rails 4, 4 'are connected to lifting devices 12 which are connected to the

Side walls 7 are attached. In FIGS. 2, 3a and 3b, only one is in each case

Lifting device 12 visible. It is understood that in the embodiment shown, each rail 4, 4 'is connected to a lifting device 12. In one not

the service box only one lifting device 12. This can with only one side wall 7 of the base member 6 or with two itself

be connected opposite side walls 7 of the base element 6. The lifting devices 12 can transfer the rails 4, 4 'from a first plane to a second plane and vice versa. The rails 4, 4 'preferably run parallel to one another, and likewise parallel to two opposite side walls 7. The rails 4, 4' receive the door edges 5, 5 'in guide grooves 14 provided for this, so that the door 3 can be displaced and guided in the Rails 4, 4 'is added. The rails 4, 4 'each have a guide groove 14. This runs in the longitudinal direction of the rails 4, 4 'and is dimensioned so that the guide elements of the door 3 can be slidably received therein. The guide grooves 14 are open at least on one side, so that the guide elements of the door 3 can be moved out of the guide grooves 14 on this one side when opening the door 3.

Between the rails 4, 4 'or between the lifting devices 12, in one embodiment, a connecting element 8 is arranged. The

Connecting element 8 can with both rails 4, 4 'and / or with both

Lifting devices 12 may be connected so that the rails 4, 4 'and the lifting devices 12 are coupled to each other. As a result, the rails 4, 4 'move synchronously during a lifting operation of the lifting devices 12. The

Connecting element 8 gives the lifting devices 12 and the rails 4, 4 'mounted thereon additional stability.

In the embodiment shown, the rails 4, 4 'have an extension 10. The extension 10 is part of the lifting devices 12 and serves to connect the rails 4, 4' with other components of the lifting devices 12, such as pivoting elements eleventh

A side wall 7, over which the door 3 can be pushed, can be chosen freely. Thus, the service box 1 of Figure 2, when installed in a control panel 2 of Figure 1, be opened up, down, left or right. Preferably, an opening direction is selected such that when the door 3 is open no other functions such as the display 20 or the

Control elements 21 are covered. In addition, the choice of the opening direction of the door 3 can be adapted to other conditions of the elevator car, such as

For example, the arrangement of cabin walls, car doors, design elements, handrails, or lighting. FIGS. 3a and 3b show a service box without a door. In Figure 3a, the lifting devices 12 are in a first position and the rails 4, 4 'are in a first plane. In Figure 3b, the lifting devices 12 are in a second position and the rails 4, 4 'are in a second plane, the second plane being higher than the first plane.

In an exemplary embodiment, the lifters 12 include

Swivel elements 11 which are fixed to the side walls 7. By the

Swivel elements 11, the rails 4, 4 'raised in an arcuate movement. A length of the pivoting elements 11 is preferably chosen such that upon transferring the lifting devices 12 from the first to the second position the rails 4, 4 'are raised to the desired height so that the door 3 can be displaced over a selected side wall 7. The lifting devices 12 may additionally comprise spring elements (not shown), which a

Support lifting movement in one direction.

The service box shown in Figures 2, 3a and 3b has supports 13 which are arranged in corners of the base element 6. These supports 13 are cylindrical, with a circular base of this cylinder on a bottom of the

Basic element 6 is. The supports 13 are arranged such that the

Lifting devices 12 are limited in their movement. As a result, the supports 13 prevent the lifting devices 12 from being lowered too far and that the door 3 can sink into the base element 6. In addition, in the columns 13

Spring elements may be arranged, which support a lifting and or lowering of the lifting devices 12 from the first level to the second level and vice versa.

In addition, the lifting devices 12 may comprise a holding device, which holds the lifting devices 12 in their first and or second position.

For example, the lifting devices 12 can be held in their first position, so that the door can not open spontaneously, but can be released from the holding device by a pressure on the door. In another embodiment, the lifting devices 12 are held in their first position. Only by the operation of a key in a designated lock while the fixture can be solved.

In another embodiment, the lifting devices 12 are held in their second position by the holding device. This may be desirable to avoid or prevent spontaneous closure of the door.

In an exemplary embodiment, the service box has one

Locking mechanism for the door 3 on. When the door 3 is completely open and / or completely closed, and / or at a defined position therebetween, the door 3 engages in the locking mechanism provided in the rails 4, 4 '. As a result, the door 3, for example, must not be held if it would close in the open state by gravity. In one

Embodiment, the locking mechanism consists of cams on the door 3 and cooperating recesses in the rails 4, 4 '.

Figure 4 shows an alternative embodiment of the lifting devices 12. Here the rails 4, 4 'are raised in a linear movement. In FIG. 4, the

Lifting devices 12 shown in a second position, in which the

Lifting devices 12 protrude and in which a door (not shown) in the rails 4, 4 'could be moved. The rails 4, 4 'have in this embodiment a differently shaped extension 10 than the rails 4, 4' in Figures 3a and 3b. The extension 10 is also connected in this embodiment with other components of the lifting devices 12. The extension 10 has

rail-shaped elements which are perpendicular to the rails 4, 4 'and which are slidably connected to other components of the lifting devices 12. By a displacement of these rail-shaped elements relative to other components of the lifting devices 12 and relative to the base element 6, the rails 4, 4 'transferred from the first to the second level and vice versa. In the embodiment shown in Figure 4, no connecting element 8 is provided. FIGS. 5a and 5b show components of a further embodiment of the invention

Lifting device 12 (without extensions 10 of the rails 4, 4 '). In each case only one side wall 7 of the service box is shown. It is understood that in one

Use state, a second lifting device 12 is arranged on an opposite side wall 7, not shown. In Figure 5b is the

Lifting device 12 in a first position, and in Figure 5a is the

Lifting device 12 in a second position. Rails are not shown in Figures 5a and 5b. The lifting device 12 of this embodiment comprises scissor elements 16, 16 ', guide cams 18 and guide slots 19. The guide cams 18 are attached to the scissor elements 16, 16'. In this embodiment, it has two upper, two lower and a central guide cam 18. Each scissor element 16, 16 'has a respective lower and an upper guide cam 18. The middle guide cam 18 is connected to both scissor elements 16, 16' and connects them with each other , Each guide cam 18 is mounted in a respective guide slot 19. Two upper guide slots 19, which support the two upper guide cams 18, are arc-shaped. A middle guide slot and two lower guide slots, which the middle respectively the two lower

Guide cam 18 store, are elongated and formed without bends. When the lifting device 12 is transferred from the first position to the second position and vice versa, the guide cams 18 are displaced in the guide slots 19. Upon lifting the door (not shown) by hand, the scissor elements 16, 16 'are vertically lifted and simultaneously horizontal merged. For example, if the lifting device 12 is moved by a biased spring, horizontally bringing the scissor elements 16, 16 'together raises the rails and door (not shown in this illustration) vertically.

When operating a service box according to the invention, it is possible, for example, to proceed as follows. When the door 3 is closed, the first

Lifting devices 12 released from the holding device. This can be done for example by means of a key or by pressing the door 3. Then the Lifting devices 12 and thus the door 3 is guided from its first position to its second position. This can be done, for example, by hand or with the action of a preloaded spring. As a result, the rails 4, 4 'and the door 3 received therein move from their first level to their second level. Now the door 3 is moved in the rails 4, 4 'and thereby opened. this happens

preferably by hand. When fully open door 3, the door is preferably held in the locking device. Now controls of functions that are housed in the service box can be operated without the door 3 must be kept. After operating the controls of functions, the door 3 is closed again. In this case, the door 3 is released from the locking device and moved in the rails until it is located substantially directly over the opening of the service box. Then, the lifting devices 12 are transferred from their second position to their first position, so that the rails 4, 4 'and the door 3 are transferred from the second level to the first level. This process is preferably done by hand. When the door 3 is closed, the holding device is now actuated. This can be done with a key and a lock, or by snapping a Hackens, so that the lifting devices 12 are automatically hooked when closing in the fixture. Instead of rails 4, 4 ', other types of mechanisms for transferring the door 3 from a first level to a second level may also be used. Various embodiments are available to the person skilled in the art. For example, the door 3 may be suspended via a single rotary element. This single one

Rotary element is preferably arranged near a corner of the door 3. With a ninety degree clockwise or counterclockwise rotation, the door 3 releases the opening of the box-shaped base 6 so that thereon

accommodated controls are accessible. The rotary member comprises a lifting device 12 and may have a holding device to hold the door 3 in a certain position. In this embodiment, no rails 4, 4 'necessary because the door is rotated away.
