Exemplary arrangements relate to apparatus that provide temporary releasable electrical connections.
Sockets as electrical installation equipment are used as part of the building installation technology and are generally mounted at a fixed location. They provide the voltage for electrically powered devices which consume electricity. Sockets in worktops, such as kitchen countertops, are often only made accessible for the duration of the use thereof. To perform work in the kitchen or for visual as well as safety-relevant reasons, the sockets are often covered. To connect the devices, the sockets can usually be opened for access. When open, the voltage connections protrude from the countertop, into which they are installed, and are thus visible. In this position, the connections can be connected to the socket insert. This has the disadvantage that the socket housing and the connections are arranged on the countertop, for example a kitchen countertop, so as to always be visible. Depending on the area and purpose of application, the sockets can be covered by means of the above-mentioned hinged covers in order to avoid the entrance of foreign objects and also in order to prevent unauthorized access.
DE 24 58 243 A1 discloses a protective device for installation elements, such as sockets and switches, comprising an automatically closing cover flap, which covers the installation element so as not to be accessible. A rotatable cover plate comprising a safety bolt is arranged at the cover flap, by means of which safety bolt the opening of the cover flap is made possible in that the safety bolt can be brought into operative and inoperative position by rotating the cover plate.
Devices, which can be pivoted out of a countertop or the floor and which are embedded, for example, underneath the countertop, are known as well. The opening of the cover is required for activation purposes and to access sockets therein.
DE 202 09 189 U1 discloses an under floor distribution box for electrotechnical purposes comprising a cover and a cord outlet comprising a closing flap, which can be pivoted around a cover-side pivot axis into an open position, wherein the closing flap has a lever underneath the cover, and a push button can be activated, so that the lever and thus the closing flap can be pivoted into an open position by pushing the push button.
It is a disadvantage of the known coverings that the covers protrude beyond the remaining components, for example of the piece of furniture, into which sockets are to be integrated, both in the closed position and in the open position. In addition, movable covers wear out and lose their functionality. Rattling can result.
Exemplary arrangements described herein provide a covering, which provides for a closable, flat assembly for a socket construction.
An installation element device for electrical connections, that includes in particular sockets that accept electrical connectors of different types, as well as USB or other connections, is disclosed. Said installation element includes in particular a socket element. The device includes a housing outer cover for a base housing, respectively, comprising socket access openings, as well as an inner base housing comprising one or several sockets arranged therein. Different options for covering the sockets will be described below.
The exemplary device has the stationary base housing, and the housing outer cover, comprising a stationary upper housing screen which is alternatively referred to herein as a cover. Openings, which make it possible to access the sockets, are formed in this stationary upper housing screen.
In addition, the device has a rotatable device, by means of which the above-mentioned openings of the housing screen can be opened or closed. The exemplary rotatable device is a rotatable rotary disk, which is alternatively referred to herein as a plate. The rotary disk is arranged at the base housing or an inner housing, which is formed in a stationary manner. Alternatively to the rotary disk, the rotatable device can be formed in any other suitable form, for example as rotary vane, rotary cam, or other movable structure.
The exemplary rotary disk, which is arranged at the base housing or the firmly installed inner housing, can be rotated with respect to the outer, stationary housing outer cover or screen, which is firmly connected to the base housing. The upper housing outer screen of the stationary outer housing cover has size-adapted insertion holes which are alternatively referred to herein as socket access openings for the acceptance of electrical connectors such as plugs of devices that consume electricity respectively, depending on the number of the sockets installed in the base housing. These are usually two or three sockets for each device, thus either a duplex or a triplex arrangement. However, the arrangement of one or of more than three sockets is also possible.
The rotary disk is arranged at the stationary inner base housing in such a way that in this stationary inner housing the individual socket devices are positioned so as to correspond exactly to the corresponding socket access openings of the stationary upper housing outer screen of the outer housing cover, so that the corresponding plugs or electrical connections, respectively, of the electrically powered devices can be inserted into the sockets after the opening through the rotary disk. Only the rotary disk, which is movably secured to the inner base housing, is rotated in such a way that the openings are either covered or open, and the connections, i.e. the sockets, can thus be accessed from outside the stationary outer housing cover. During the non-use of the sockets, the rotary disk can be activated again, and the openings of the stationary upper housing outer cover can be covered, in that the position of the rotary disk is changed in such a way that perforated screens formed at the rotary disk can move into or lock in place with the socket access openings of the housing outer cover, respectively, and the surface of the cover overlying the socket element is thus covered in a planar or flush manner, respectively.
The rotatability of the rotary disk can take place by means of different rotary mechanisms. The exemplary rotary mechanisms can be:
In the case of the described helix principle, guide elements in the helical turns of the gate element or of the rotation sleeve lead to the rotation due to an axial degree of freedom. This principle of the helical turns is also usable in that the gate element or the rotation sleeve represent a partial region of the rotary risk or of the activation element.
Another type of the rotary disk control in electronic form is the use of an IC timing element. If the locking position of the rotary disk is not reached within a specified time, the electronics reverses the polarity of the DC connections, as a result of which the reversal of the direction of rotation and thus a clamping protection is realized.
In the case of all mentioned rotary mechanisms, a pivotable or rotatable device, respectively, the inside rotary disk or plate formed for this purpose, which is arranged within the stationary base housing, but not an upper covering on the outside of the stationary device is rotated for covering or making accessible, respectively, the sockets formed in the device for providing releasable electrical connections. A releasing and movement of an exposed upper covering is not required. A wear-out or a rattling, respectively, of a movable exposed cover within the insert opening can thus be prevented in the exemplary arrangements.
In alternative exemplary arrangements three springs can also be arranged.
The socket or the sockets, respectively, arranged in the inner base housing serve as electrical plug connectors between conduits such as cords of electrically powered devices. They are used for the electricity supply. The wired electric plug systems form the releasible interface between electrical devices and the current source supplying them. Equipment is usually supplied via sockets with household current of single-phase of 230 Volts or three-phase alternating current (AC current) with 400 Volts, there are also standardized sockets for 12V direct current. A Schuko (protective contact) household socket provides a voltage of 230 V and up to 16 Amperes, thus up to an output of approximately 3680 Watts. If this output is exceeded, the fuse generally turns off. A socket used for the electrical connection for the household current may be connected to a distribution board of the building installation and generally guides one of three outer conductors, the neutral conductor, and the protective conductor. Voltage-conducting sockets with “female” design, which have contact openings facing inwards, are also referred to as bushes or coupling. According to the exemplary arrangements sockets may include, USB connections or the like and can also be integrated in the exemplary arrangements. Socket models, such as socket units of a foreign design, such as, e.g., of Italian, English, French, or also Swiss design, can likewise also be integrated.
The exemplary device providing a coverable socket element is arranged in particular at a kitchen countertop or any other worktop, thus for example a desk or the like. The kitchen countertop refers to the work surface in the kitchen. It is usually firmly mounted and forms the horizontal closure of built-in kitchens for example with a depth of approximately 60 cm and a working height of 85 cm to 110 cm. The kitchen countertop can also be used for so-called island kitchens.
The device according to exemplary arrangements thereby has the advantage that a masking of the openings for sockets, which is secure, can be operated easily, and has a low rate of failure, is attained by means of a simple activation.
Further advantages and advantageous designs of exemplary arrangements can be gathered from the following detailed description, the drawings, and the claims.
Exemplary arrangements will be described in more detail below on the basis of the enclosed schematic drawings, in which:
An apparatus configured to provide temporary releasible electrical connections which is sometimes referred to herein as an installation or socket element device, respectively, is illustrated in
The rotary disk 30 which is alternatively referred to as a plate is illustrated in
In the case of the second exemplary arrangement elements having similar functions are described using the same reference numbers as in the first arrangement. The movable rotary disk 30, which is activated according to the “ballpoint pen principle”, is thus arranged. On the inner side, for example, the base housing 01 has in particular two fastening domes 12, which are arranged in such a way that they protrude into the inner housing 07 and are screwed thereto. A hollow space, into which the rotary disk 30 is movably arranged, is thus created between inner housing 07 and the base housing 01. The activation takes place according to the “ballpoint pen principle”, wherein an activating device, such as, for example, the actuating button 45, is formed. Several parts form the cover of the socket. Inside, the base housing the rotary disk 30 is rotated around an axis of rotation. The pressure or rotary spring 59, respectively, is arranged in the lower region of the device. The rotary disk 30 is opened through rotation by means of the “ballpoint pen principle”. In particular three guide ribs 51 act against in particular three recesses. The rotary disk 30 is thus released and is pulled downwards in order to unlock and enable access to the sockets. The rotary spring 59 acts on the axis of rotation with a certain torque. When releasing the actuating button 45, the latter moves in the direction of the top side of the outer housing 01. The pressure spring 58 strikes against this upper region. The plate opening thus rotates open into corresponding aligned relation automatically with respect to the socket in the stationary base housing 01, and housing outer cover 10, and the socket can be accessed and used. The actuating button 45 sticks out for activation purposes—as in the case of a ballpoint pen. The guide ribs 51 are guided in the axis of rotation. The rotary disk 30 is rotated by means of the actuating button 45, and the rotary spring 58 is biased. Due to the axial play, the actuating button 45 is enabled to be moved downwards, the plate rotates from the socket access position to the socket blocked position and the sockets are covered in a flat manner again. In the cooperation of the actuating button 45 with the guide ribs 51, the rotary disk 30 is guided upwards in its function as cover plate. Two springs 58, 59 can be formed. The rotary disk 30 has plate openings, which correspond with the through socket access openings of the housing top part 10 in such a way that they can be rotated into an open socket access position or a socket blocked closed position by activating the actuating button 45.
The rotation of the rotary disk 30 takes place via helical turns. The rotary disk 30, which is arranged, for example, at a firmly arranged inner housing or—as illustrated—within the base housing 01 with vertical and rotational play for the freedom of movement, can be rotated by means of a rotation sleeve around helical turns of the helical gate 80, for example two helical turns, and can be rotated, e.g. >90°. By pushing axially down on the actuating button 60, the rotary disk 30 is released from its locking position, and the rotary spring 92, which represents a connection under bias with the rotation sleeve and the housing bottom 20, can relax and rotates the rotation sleeve. An axially movable axis, which engages with the helical turns of the rotation sleeve via moldings, is arranged in the interior of the rotation sleeve. In its interior, the axially movable axis has an angular geometry, which protrudes in a complementary manner from the housing bottom 20 with a molding into the axis. The axis is thus pushed out of the base housing 01 by rotation of the rotation sleeve and brings the actuating button 60 into a raised axially outward extending position. The rotary disk 30 is likewise rotated from a closed socket blocked position into an open socket open position by means of the rotation of the rotation sleeve via followers 09, which are arranged at the end of the axis of rotation of the rotary disk 30 and which are engaged with the rotation sleeve. By pushing down the actuating button 60, the rotation sleeve is rotated in an opposite direction of rotation via the movable axis, the rotary spring 30 is biased, and the rotary spring 92 is rotated into the closed end position. A pressure spring 91, which is arranged operatively between the rotation sleeve and the rotary disk 30, pushes the rotary disk 30 into the locked position. The rotary disk 30 has plate openings, which correspond with the through socket recess openings of the housing top part 10 in such a way that they can be rotated into an open or closed position by activating the actuating button 60.
The release of the locking of the rotary disk 30 from a locked position takes place by pushing axially down on the actuating button 101 against the pressure of a pressure spring 90, which is arranged between the axial bearing of the rotary disk 30 and an electrical drive, the electric motor 100. When reaching the bottom extent of axial travel of the actuating button 101, the switch 104 is activated, and changes electrical condition which turns on the electric motor 100 responsive to the control circuit. The electric motor 100 rotates the rotary disk 30 from the socket blocked position into the socket access position and to operative engagement with a stop via an axial connection. When rotation of the rotary disk 30 stops due to operative engagement with the stop in the position, the current increases, the circuit detects the current increase, sets the switch 104 to off, turns off the supply of electricity to the electric motor 100, and reverses the polarity of the DC connections to the motor. The pressure spring 90 axially pushes the rotary disk 30 into a locked position. The movement of the rotatable plate to the socket blocked position from the socket access position can take place in the same way as the opening, by pushing down the actuating button 101. The exemplary circuit is designed in such a way that, on the one hand, it realizes the reversal of the direction of rotation and, on the other, hand, represents a clamping protection.
Thus the exemplary arrangements described herein achieve improved operation, eliminate difficulties encountered in the use of prior devices and systems, and achieve the useful results described herein.
