Description

The invention relates to a device for receiving and locking objects on a support frame according to the preamble of claim 1 and to a support frame for use in such a device according to the preamble of claim. 6

From the AT 14 852 U1 a carrier arrangement for the storage and / or transport and / or cleaning of dishes or other objects is described. The support assembly consists of a support plate with at least one lattice-shaped structure, which is formed by square openings. In each of the receiving openings, a mounting base can be used, which has an outer contour through which a clamping or positive connection in the form of a thread is present and which cooperates with the inner contour of the respective receiving openings such that the mounting base is held in the respective receiving opening position.

A disadvantage of the design of the support plate has been found that this is subject to considerable increases in temperature increases, because the support plate is made of a plastic material and the width of the receiving openings enclosing webs of the support plate are based on the wall thickness of the webs in one Designed ratio by which a delay of the respective webs arises when corresponding gravitational forces act on the support plate. The grid or webs forming the carrier plate are therefore not dimensionally stable and are distorted, in particular in the case of temperature increases. The Support plate of the aforementioned type is to be used in dishwashers in which only a temperature of about 60 ° C prevails. Consequently, such a carrier plate can not be used in applications in which a medium temperature of above 100 ° C prevails. High-precision metal components are used in the connector body to store and clean them. During the cleaning process prevail temperatures of about 120 ° C and more and the cleaning media, especially water with cleaning solutions, meet directly on the support plate.

In addition, the known from the aforementioned prior art support arrangement for such high-quality precision components can not be used, since the connection between the support plate and the objects to be cleaned due to the clamping fixation of the mounting base in the respective receiving openings has a game, so that the mounting base at corresponding forces transmitted by the medium could wobble and consequently the objects connected to the mounting base could hit each other. In dishwashers is sufficient space or space available and small touches between the stored items in the dishwasher do not necessarily cause damage or the dishes to be cleaned is not damaged when it touches or hits each other. In addition, the clamping connection between the mounting base and the receiving opening can be lost, namely, when the temperatures of the medium are so high that a spiral or air gap arises between them.

The patent applicant has recognized this problem and developed solutions in the recent past, by which this problem to support the high-quality precision components to be avoided during the cleaning process. For example, from the EP 2 860 126 A1 a device for receiving and locking objects has become known, which has a wire frame that is formed of wire columns which are parallel or perpendicular to each other. The respective parallel wire strands are arranged in one plane and the wire strands forming the other level extend below this level, so that the wire strands running perpendicular to one another are used as a fastening aid for a retaining base which can be inserted into the respective receiving opening can. In the support base of a connecting body therefore two clamping grooves are incorporated which extend in different planes. In this case, two opposite clamping grooves are each assigned to the parallel wire strands of one of the planes of the receiving opening. By rotating the connecting body within the receiving opening, a locking between the retaining base and the wire strands enclosing the receiving opening can thus be created so that the connecting body is held in a position-oriented manner in the respective receiving opening or on the wire strands. The bottom of the connecting body serves as a stop help.

The wire strands are disadvantageously made of a metallic material, while ensuring that no distortion occurs at corresponding temperature effects and the grid-shaped support frame is dimensionally stable, however, the manufacturing cost of such support frames are enormously high, since these are formed on the one hand of wire strands, which is time consuming in Nodes are to be connected together.

In addition, the adjacent receiving openings, which lie laterally next to an already used receiving opening, can not be used for further connecting bodies, since the connecting body already used overlaps the wire strands and consequently they are no longer free for adjacent fixings of connecting bodies. Thus, a significant number of receiving openings to be released and the cleaning process is not sufficiently optimized, since many of the seats are unoccupied at the receiving openings.

It is therefore an object of the invention to provide a device for receiving and locking objects as well as a support frame for such a device that is cost-effective and quickly produced on the one hand, and on the other hand, the cleaning process, especially for high-quality precision components, with a sufficient cleaning temperature is optimized, without being subjected by the temperature effects, the device and in particular the support frame of the device to a delay or wear.

In addition, the connecting body should be independent of their space size mountable on support frames, identify the receiving opening differently sized edge length.

This object is achieved by the features of the characterizing part of claim 1 and by the features of the characterizing part of claim 6.

Further advantageous developments of the invention will become apparent from the dependent claims.

Characterized in that at two mutually parallel webs each projecting into the center of the receiving opening plate-shaped projection is formed or provided that the projections in one of the receiving openings laterally offset from each other are based on the perpendicular to this axis of symmetry and that the support base of the respective Connecting body can be locked to the projections and / or that the webs have a smaller wall thickness than the width of the webs and that in the interior of the respective receiving opening on the webs two opposing projections are formed or mounted, based on this perpendicular to this axis of symmetry laterally with an identical offset mirror image offset from one another, it is achieved that on the one hand the device is formed even at high temperature influences of more than 100 ° C from a dimensionally stable support frame, that on the other hand, the object on the Supporting frame are held and that also the support frame is inexpensive to produce in plastic injection molding and its structure even after a variety of temperature increases due to detergents without delay, since the webs of the support frame in particular in the gravitational direction have a considerable width, the delay due to temperature fluctuations counteracts.

In addition, the respective receiving opening can be configured as a square, so that an optimum number of receiving openings can be provided in the supporting frame and since each receiving opening can be actuated with a connecting body, the space provided by the supporting frame is optimally utilized. because every opening is verifiable. Consequently, a variety of objects can be cleaned without leaving space on the support frame unused.

In addition, the cleaning agent used can optimally flow through the respective support frame, which are often stacked one above the other, so that the cleaning agent can flow in the direction of gravity quickly and in sufficient quantities, since the diameter or edge lengths of the receiving openings are proportioned substantially larger than the dimensions Wall thickness of the webs. Consequently, the webs require a much smaller area than the released from the respective receiving opening surface can be configured.

The attachment of the respective support base on the webs is effected in that attached to these two opposite projections or provided, which are arranged laterally offset relative to the axis of symmetry of the receiving openings. Thus, the support base of the respective connecting body can be twisted inserted into the receiving opening and as soon as the bottom of the connecting body rests on the top of the support frame, the support base can be rotated in the respective direction to the projection, so that the incorporated into the support base and oppositely extending clamping grooves interact with the respective projection and engages around the projection in the manner of an undercut, whereby the retaining base is fixed in a position-oriented manner on the two projections. Such a latching of the retaining base on the projections can be brought about quickly and, if necessary, also be solved again without destruction.

Furthermore, the fixing method according to the invention between the holding base and the projections provided in the receiving openings, that any size of connecting bodies can be used provided that the respective support base is configured identically. Consequently, connecting body can be used, the bottom of which is configured substantially larger than the edge length of the receiving opening. Namely, the connecting body should be as identical as possible to the outer circumference of the inserted object in order to prevent the object from wobbling in the connecting body and possibly touching an adjacent object and causing damage due to such contact.

Furthermore, any edge length can be provided for the receiving opening, because the length of the projection can be fitted to the edge length. However, then the respective support base can be locked to two opposing projections, because the support base is still used between the laterally offset mutually extending projections and connected by rotation in the direction of the projections with these. The longer the edge length of the receiving opening, the longer also the respective projection and vice versa form.

In the drawing, a device is shown, which is explained in more detail below. In detail shows:

FIG. 1

FIG. 3

the support frame according to FIG. 1 in plan view and in section,

FIG. 4a

the support frame according to FIG. 1 with an inserted connecting body from below,

FIG. 4b

the support frame according to FIG. 4a from above,

FIG. 5a

the support frame according to FIG. 1 with four connecting bodies whose diameter is less than the edge length of the respective receiving opening, and

FIG. 5b

the support frame according to FIG. 5a with three connecting bodies whose diameter is dimensioned larger than the edge length of the respective receiving opening.

Out FIG. 1 it can be seen that a device 1 is to be made available by which a plurality of connecting bodies 2 can be fastened to a support frame 4. Through the respective connecting body 2, an object 3, for example a workpiece as a high-precision component, is to be held in order to be able to store, transport and clean these objects 3 safely.

The support frame 4 is formed by webs 7, 8, which run in pairs parallel to each other. Consequently, two pairs of webs 7, 8 form one of the receiving opening 9, because the webs 7, 8 are perpendicular to each other. The edge length of the receiving opening 9 is identical, so that a square receiving opening 9 is formed.

In the corner regions of the support frame 4 holes or through holes are provided in which spacers are used to stack a plurality of support frames 4 can be stacked.

On the connecting body 2, a round bottom 10 is provided, on whose one end face a rectangular neck base 11 and on the opposite end side one or more holding or receiving elements 12 are provided, which include a space in which the respective object 3 can be stored. The support base 11 can in one of the receiving openings 9 - as will be explained in more detail below - used and positionally fixed to the support frame 4. The support base 11 extends in alignment with the longitudinal axis 6 of the respective connecting body 2.

The bottom 10 of the connecting body 2 has a diameter which corresponds approximately to the edge length of the receiving opening 9, so that the supporting frame 4 facing underside of the bottom 10 rests on the top 5 of the support frame 4 and is supported by the webs 7, 8. Alternatively, in each case one support lug 24 can be formed or provided on two opposite webs 7, 8 be, which projects into the center 13 of the respective receiving opening 9 and serves as a stop for the support base 11 of the connecting body 2 to be used, so that also connecting body 2 with a smaller diameter of the bottom 10 than the edge length are reliably supported on the top 5 of the support frame 4 ,

An axis of symmetry running parallel to the webs 7, 8 along one of the rows of receiving openings 9 is identified by the reference numeral 14 and serves as a reference for the arrangement of projections 21, 22.

FIG. 2 can be seen how the support base 11 of the receiving body 2 is configured and in the respective receiving opening 9 of the support frame 4 can be locked. Namely, the retaining base 11 has a rectangular outer contour with four edge lengths 16, 17, 18 and 19. At the longer edge lengths 18, 19 clamping grooves 15 are incorporated, which form a U-shaped inner contour in its cross section together with the underside of the bottom 10. The two shorter dimensioned longitudinal edges 16, 17 between the clamping grooves 15 are designed plan. The perpendicular thereto extending longitudinal edges 18, 19 carry the clamping grooves 15. Furthermore, the opposite clamping grooves 15 are arranged mirror-inverted to each other.

At the respective side wall of the webs 7, a projection 21, 22 is formed or provided in each case, which are designed plate-shaped. The projections 21, 22 thus protrude into the center 13 of the respective receiving opening 9 and are spaced from the top 5 of the support frame 4. The projections 21, 22 extend in a common plane and are perpendicular from the web 7 from.

In addition, the two existing in one of the receiving opening 9 projections 21, 22 relative to the axis of symmetry 14 are arranged mirror images offset from one another. The projection 21 has an offset V which extends to the right of the axis of symmetry 14 and the projection 22 has an offset V which extends to the left of the axis of symmetry 14. In terms of magnitude, the offset V of both projections 21, 22 to the axis of symmetry 14 is identical. The geometric dimensions of the projections 21, 22 are also identical.

The diagonal distance between two corners of the projections 21, 22 corresponds approximately to the length of the shorter, plan designed longitudinal edges 18, 19 of the support base 11 so that it can dive between the projections 21, 22, until the bottom 10 on the top 5 hits. Then, the two clamping grooves 15 of the retaining base 11 extend in the plane formed by the projections 21, 22.

Consequently, the support base 11 of the respective connecting body 2 can be inserted into the receiving opening 9 and placed there first, until the bottom 10 rests on the top 5 of the support frame 4 and / or the support lugs 24. The two clamping grooves 15 extend in the same plane from the projections 21, 22 and the inner contour of the clamping grooves 15 is adapted to the outer contour of the projections 21, 22. Once the retaining base 11 is inserted into the receiving opening 9, the connecting body 2 can be rotated by about 45 °, so that the clamping grooves 15 in the direction of the respective projection 21, 22 is movable. Thus, there is a locking of the support base 11 to the two projections 21, 22 in the manner of an undercut, since the clamping grooves 15 in the assembled state of the support base 11, the projections 21, 22 surround partially. By suitable constructive measures, the non-positive operative connection between the support base 11 and the projections 21, 22 can be improved, for example, in which provided on the projections 21, 22 hills that dive into the clamping groove 15 abut against these.

In FIG. 3 the structural design of the support frame 4 is shown in three views. The fields formed by the receiving opening 9 can be equipped with one of the connecting body 2.

From the FIGS. 4a and 4b It can be seen how the respective connecting body 2 in the receiving opening 9 can be inserted and locked by rotation with the projections 21, 22, without the longitudinal edges 16,17, which are designed plan, past the projections 21, 22, until the Longitudinal edges 18, 19 engage with the clamping grooves 15 into engagement with one of the two projections 21, 22 and are locked thereto.

The size of the respective connecting body 2 can according to the FIGS. 5a and 5b vary. As long as the diameter of the connecting body 2 extends inside the respective receiving opening 9, each adjacent receiving opening 9 can be equipped with a connecting body 9, so that all existing receiving openings 9 can be provided with an object 3 to be cleaned. Once the connecting body 2 has a larger diameter than the edge length of the receiving opening 9, the connecting body 9 is beyond the predetermined by the webs 7, 8 boundary of the receiving opening 9, so that adjacent receiving openings 9 are covered and therefore not for receiving further connecting body 2 can be used.

The support frame 4 is particularly dimensionally stable, since the wall thickness of the webs 7, 8 in relation to the width B of the webs 7, 8 is dimensioned much smaller. In addition, the width B in the direction of gravity, so that self-weight forces affect the dimensional stability of the support frame 4 only slightly and the webs 7, 8 counteract these self-weight forces, since the width B of the webs 7, 8 is formed accordingly. Especially in the case of temperature influences, these geometric configurations counteract distortion of the support frame 4.

In addition, the support frame 4 can be inexpensively manufactured in a plastic injection molding process and each connector body 2 can be attached regardless of its size to an identically designed support frame 4, namely, if the respective used support base 11 of the connecting body 2 identical, that is independent of the size of the connecting body. 2 , is designed. Even if the edge length of the receiving opening 9 are increased or decreased, each of the correspondingly configured retaining base 11 can be locked to the support frame 4. It is only in the production of the support frame 4 make sure that the edge length of the receiving opening 9 with the length of the projections 21, 22 in an identical ratio, such that the support base 11 can be inserted into the receiving opening, that is, the longitudinal edges 18, 19, which are designed plan, can be rotated past the projections 21, 22 over and that the longitudinal edges 16, 17 can be moved with the clamping grooves 15 to the projections 21, 22 by twisting.

When the support frame 4 is made in a plastic injection molding process, a one-piece component is formed, which is easy and handy to use or usable.
