    专利说明:

    The present invention relates to a device for movably securing a laboratory unit to a horizontally extending, elongated ceiling support mounted in the region of a room ceiling, which has at least one first groove extending in the longitudinal direction of the ceiling support.
    The demands on modern laboratories are diverse nowadays. Rapid adaptability of the laboratory by users is of enormous importance and will become even more important in the future. For this purpose, so-called media ceilings have been developed, which integrate all liquid laboratory media as well as gases, electricity, data lines, lighting, air conditioning as well as supply and exhaust air ducts and enable effective and variable use of the laboratory due to their high adaptability to changed conditions.
    With full or partial area use, the media are guided to the respective work area through laboratory media columns, laboratory media traffic lights or laboratory media wings, to name just a few examples, which are mounted in particular in the area of the ceiling of the laboratory. A laboratory media column is generally understood to be a laboratory media supply extending in a vertical direction, which essentially supplies the laboratory space below with the laboratory media made available by the laboratory media column and either on the laboratory ceiling, or on the above-mentioned laboratory media ceiling, or even on the underside a wall cabinet is mounted. A laboratory media traffic light is usually understood to mean a laboratory media supply extending in the horizontal direction, which is attached to the laboratory ceiling or to the laboratory media ceiling with the aid of two vertical rails. In contrast to a laboratory media column, the laboratory media traffic light can supply a larger linear area of the laboratory with laboratory media. Both the laboratory media column and the laboratory media traffic light have the laboratory media connections at chest or head height of a normal adult. A laboratory media wing, on the other hand, runs in the horizontal direction over a significantly larger area of the laboratory space, specifically at a height above the head of a normal adult person. The laboratory media wing can be attached to the laboratory ceiling as well as to the laboratory media ceiling.
    The attachment of such laboratory media supplies or other hanging laboratory structures, hereinafter generally referred to as laboratory units, with commercially available connecting elements, such as assembly rods and screws, is very complex and usually cannot be done without specialist staff. If it is also desired to be able to move, additional aids must be provided. A lifting device is also required as an assembly aid, as assembly is tool-specific. In addition, there is no fall protection. This must be added in a second step in order to prevent it from falling during later use.
    An object of the present invention is accordingly to minimize the disadvantages associated with the prior art, sometimes even to eliminate them. In particular, it is an object of the present invention to provide a device and a system which ensure tool-free assembly of the above-mentioned laboratory media supplies on a carrier present in the area of the laboratory ceiling without additional fall protection.
    This object is achieved by the subject matter of claims 1 and 16. Optional or preferred features are specified in the dependent claims 2-4.
    According to a first aspect of the invention, a device for movably attaching a laboratory unit to a horizontally extending, elongated ceiling support mounted in the region of a room ceiling, which has at least one first groove extending in the longitudinal direction of the ceiling support, is provided. The device according to the invention comprises (i) a sliding element which receives the weight of the laboratory unit and which can be brought into engagement with the first groove of the ceiling support such that the device is movable in the longitudinal direction of the first groove of the ceiling support, the height of the sliding element being the height of an access opening corresponds to the groove, (ii) a holding element for releasable fastening of the laboratory unit, and (iii) at least one locking element which can be connected to the ceiling support in such a way that movement of the device in the longitudinal direction of the first groove of the ceiling support is prevented.
    Preferably, the device further comprises an anti-tipping element which is designed such that tilting of the device perpendicular to the longitudinal extension of the first groove of the ceiling support is prevented.
    The sliding element and the anti-tipping element are particularly preferably connected to one another.
    More preferably, the sliding element and the anti-tipping element extend parallel to the longitudinal direction of the first groove.
    It is advantageous if the sliding element and the anti-tipping element together form a one-piece element.
    According to a further preferred embodiment of the invention, the holding element extends perpendicular to the longitudinal direction of the first groove.
    It is also preferred if the holding element, the sliding element and the anti-tipping element together form a one-piece element.
    The locking element is preferably arranged on the holding element.
    Even more preferably, the locking element is designed so that it can be brought into engagement with a second groove of the ceiling support.
    It is also preferred if the locking element is designed so that the locking element can be brought into engagement with the second groove of the ceiling support by a first rotational movement, and that the locking element can be positively connected to the second groove of the ceiling support by a subsequent second rotational movement is.
    According to yet another preferred embodiment of the invention, the first rotary movement comprises a rotation through 90 ° and the second rotary movement a rotation through 180 °.
    Preferably, after the second rotation of the locking element, the sliding element is relieved of the weight of the laboratory unit.
    It is also advantageous if the locking element comprises a sliding block and a rotating bracket connected to it in a rotatable manner.
    Even more preferably, the device comprises two locking elements which are arranged on opposite end portions of the holding element.
    Preferably, the device is suitable for a laboratory unit, which is selected from the group consisting of a vertical laboratory media column, a horizontal laboratory media carrier, such as a laboratory media traffic light or a laboratory media wing, a laboratory hanging furniture and a lamp.
    According to a second aspect of the invention, a system is provided which comprises at least one device according to the first aspect of the invention and at least one ceiling support which has at least one first groove extending in the longitudinal direction of the ceiling support.
    The invention will now be described purely by way of example using a preferred embodiment and the accompanying figures. The figures show: FIG. 1 a perspective view of a ceiling support with a device attached to it according to a preferred embodiment of the invention; FIG. 2 shows the device of FIG. 1 in the attached state, but without the ceiling support; and FIG. 3 shows the device of FIG. 1 in the dismantled state.
    1 shows a perspective view of a carrier 10 to be attached in the area of the laboratory ceiling, which is inherently rigid and extends in the horizontal direction. This carrier can also be part of an existing laboratory media ceiling. The carrier 10 is often made of extruded aluminum and has a hollow chamber profile which comprises a plurality of grooves 12, 14 extending in the longitudinal direction of the carrier 10. The grooves 12, 14 are conventionally arranged point-symmetrically to one another in the area of the edges running in the longitudinal direction of the carrier 10. However, differently designed carriers are also conceivable. It is only important that the carrier has at least one groove 12 extending in the longitudinal direction of the carrier 10 and has sufficient stability so that it can absorb the weight of a laboratory unit explained in more detail below. The cross-section of the groove 12 can be almost any, as long as the groove 12 ensures that a component accommodated therein can be displaced and enables the fall protection described in more detail below.
    According to the preferred embodiment shown in Fig. 1, the groove 12 comprises in cross section perpendicular to its longitudinal extent an access opening and an adjoining mushroom-head-shaped bulge which has a width and a maximum height in the area of the access opening. A square bulge with a height and a width is also conceivable, so that a (lying) T-shape of the groove 12 results in cross section.
    A preferred embodiment of the invention comprises a device 20, which is shown in detail in FIG. At this point it is noted that FIG. 2 shows the device 20 in a state in which it is secured on the carrier 10.
    The device 20 is primarily used to attach a laboratory unit, not shown in FIGS. 1 to 3, to the carrier 10 in a displaceable manner. A laboratory unit can be a laboratory media column, a horizontal laboratory media carrier, such as a laboratory media traffic light or a laboratory media wing, but also hanging laboratory furniture or a lighting fixture (lamp).
    To attach a laboratory unit, the device 20 has a plurality of mounting openings or mounting bores 25, which are arranged so that a laboratory unit can be attached to the device 20 either directly on the device 20 or with the interposition of a mounting adapter or a mounting plate (not shown) . The assembly openings or assembly bores 25 are provided in accordance with FIG. 2 on a holding element 24 which, in the assembled state, preferably extends plane-parallel to the underside of the carrier 10 (see FIG. 1). Only the part of the holding element 24 on which the assembly openings or assembly bores 25, or at least a part thereof, are located, extends laterally beyond the carrier 10 in the lateral direction. According to the embodiment shown in FIGS. 1 to 3, the holding element 24 is otherwise plate-shaped or planar.
    According to the preferred embodiment of the invention shown in FIGS. 1 to 3, the device 20 furthermore comprises a sliding element 21, an anti-tipping element 23 and a bridge element 22, which are preferably formed in one piece with the holding element 24. The sliding element 21 primarily serves the purpose of enabling the entire device 20 to be displaced along the longitudinal extension of the groove 12 of the carrier 10. In addition, the sliding element 21 absorbs the entire weight of the laboratory unit to be attached to the device 20.
    The anti-tipping element 23 of the device 20 ensures in the mounted state on the carrier 10 that a laboratory unit attached to the device 20 does not tilt laterally, i.e. in a lateral direction to the longitudinal extension of the carrier 10. The anti-tipping element 23 and the sliding element 21 are preferably connected to one another via a bridge element 22. According to the preferred embodiment of the invention shown in FIG. 2, the sliding element 21 and the anti-tipping element 23 run parallel to one another and are formed in one piece. The sliding element 21 and the anti-tipping element 23 are preferably formed in one piece with the holding element 24. As can be seen in FIG. 2, the bridge element 22 and the anti-tipping element 23 form a quasi L-shape in cross-section, ie perpendicular to their longitudinal extension, with a short section (sliding element 21) on the short leg of the L-shape (bridge element 22). is attached, which runs parallel to the long leg. The length of the short section is shorter compared to the short leg.
    A fall protection of the device 20 consists in the fact that the height of the sliding element 21, the height running perpendicular to the longitudinal extension of the groove 12 of the carrier 10, is essentially the height of the access opening of the groove 12 of the carrier, to the extent that the sliding element 21 ( preferably together with a section of the bridge element 22 extending perpendicular to the sliding element 21) through the access opening into the groove 12, and that the width of the sliding element 21, viewed in the lateral direction to the longitudinal extension of the groove 12 of the carrier 10, is essentially the width of the bulge that adjoins the access opening corresponding to the groove 12. Preferred dimensions of the height of the sliding element 21 are in a range from 4 mm to 20 mm, more preferably 6 mm to 10 mm, and even more preferably the height is 8 mm. The width of the slide member 21 is preferably in a range of 4mm to 20mm, more preferably 6mm to 10mm, and even more preferably 8mm. The height and width of the sliding element 21 are dependent on the dimensions of the groove 12 and the weight of the laboratory unit to be attached to the device 20.
    When a force, which points in the lateral direction to the longitudinal extent of the groove 12, acts on the device 20, the device 20 is prevented from falling out or tilting out of the groove 12 due to the shape-conforming cross-section of the sliding element 21 with the groove 12. In such a situation, on the one hand, the form-fitting reception of the sliding element 21 in the groove 12 and, on the other hand, the height of the sliding element 21, which corresponds approximately to the height of the access opening of the groove 12, prevents the device 20 from falling out of the groove 12.
    Furthermore, at least one locking element 26, 27 (so-called quick lock) is provided, with the aid of which the device 20 can first be brought into engagement with the carrier 10 and then connected in a force-locking manner. The locking element 26, 27 preferably comprises a square slot nut 27, which is connected to a rotating bracket 26 via a shaft so that it can rotate and is preferably spring-mounted. Such locking elements 26, 27 are preferably provided on both end sections of the holding element 24.
    According to the preferred embodiment of the invention shown in FIGS. 1 to 3, the sliding block 27 engages in a groove 14 provided in the carrier 10 on its underside. For this purpose, the sliding block 27 must be aligned with the groove 14, then introduced into the groove 14 and then rotated preferably by 90 ° with the aid of the swivel bracket. In this state, the device 20 is secured on the carrier 10 to such an extent that it cannot be released from the carrier 10 independently or unintentionally by the action of a force on the part of the laboratory worker. In this state, which is shown in FIG. 2, the device 20 can be displaced along the groove 12 of the carrier 10 so that the laboratory unit attached to the carrier 20 can be moved to the desired location in the laboratory. Once the carrier 20 and the laboratory unit attached to it are positioned in the desired location, the rotating bracket 26 is preferably rotated through 180 °. As a result of this rotation through 180 °, the sliding block 27 is connected to the carrier 10 in a force-locking manner, of course in conjunction with the holding element 24.
    At the same time, with the 180 ° rotation of the rotating bracket 26, the sliding element 21 is relieved of the weight of the laboratory unit attached to the device 20. This is achieved in that the holding element 24 is at a predetermined distance from the underside of the carrier 10 before the rotation of the swivel bracket 26. If the swivel bracket is now rotated by preferably 180 ° and the holding element 24 is pressed against the underside of the carrier 10, the anti-tipping element 23, the bridge element 22 and the sliding element 21 move upwards at the same time, whereby the sliding element 21 is relieved. Only when the swivel bracket 26 is rotated again by preferably 180 ° in the opposite direction and thus the force-fit connection is canceled does the entire device 20 and thus also the sliding element 21 lower downwards, whereby the sliding element 21 is loaded again.
    In order to be able to detach the device 20 from the carrier 10, the frictional connection must, as already mentioned, be released by a preferably 180 ° rotation of the rotary bracket 26. A further rotation by preferably 90 ° causes the sliding block 27 to lower and to be received in the elongated hole 28 provided in the holding element 24, preferably flush with the surface. By receiving the sliding block 27 in the elongated hole 28, the sliding block 27 is moved out of the groove 14 provided in the carrier 10. This state is shown in FIG. 3. The entire device 20 can then be removed from the carrier 10 with the aid of a lifting and pulling movement.
    By means of the device 20 according to the invention, a laboratory unit can be slidably attached to a carrier 10 already present in the laboratory without tools. No specialist personnel or other aids, such as a lifting device or a fall protection device, as is the case in the prior art, are required for fastening. Due to the shape-conforming design of the sliding element 21 in accordance with the groove 12 of the carrier 10 and the fact that the height of the sliding element 21 essentially corresponds to the height of the access opening of the groove 12, a fall protection is integrated into the device 20 and the entire device including the laboratory unit attached to it are at the moment of the Attachment to the carrier 10 secured against falling. This significantly minimizes the risk of accidents. It is also advantageous that, due to the integrated fall protection, this can be used when assembling the device 20 or the laboratory unit cannot be forgotten. The sliding element 21 is only when moving the device 20bzw. the attached laboratory unit. When the device 20 is positively connected to the carrier 10, the latter is displaced upwards and thus relieved.
