Description

Domestic refrigerating appliance with a transport safety body

The invention relates to a household refrigerating appliance, comprising a heat insulating inner container, which is designed to limit a storage space for refrigerated goods, at least one shelf mounted in the inner container, a trained for opening and closing of the storage room door leaf having a storage space facing inside, at least a door racks is mounted, and a formed from a flat sheet by folding transport securing body having recesses. US 2,659,648 describes a refrigerator with a formed from a flat sheet of cardboard by folding transport safety body having slot-shaped recesses which are formed in a transport locking position of the transport lock body to secure a plurality of shelves of the refrigerator in the storage room.

The object of the invention is to provide a household refrigeration appliance with an improved transport safety body, which in particular can be easily and quickly mounted and can optionally fulfill extended safety functions. The object of the invention is achieved by a household refrigeration appliance, comprising a heat-insulating inner container which is designed to limit a storage space for refrigerated goods, at least one shelf mounted in the inner container, a trained for opening and closing the storage room door leaf, which has a storage space facing the inside , is mounted on the at least one door racks, and formed from a flat sheet by folding transport securing body having recesses in which the transport securing body is formed by a single fold to a cross-sectionally V-shaped bar with two legs. The recesses may be configured to secure the at least one shelf and / or the at least one door rack in the storage room in a transport securing position of the transport securing body. In its initial state, the transport safety body consists of a flat arc. The bow can be so far a flat, flat sheet or a plate from which a three-dimensional body is formed by folding, ie buckling. The transport safety body can thus be made in the manner of a cardboard. However, the sheet or the transport securing body described does not consist exclusively of cardboard or paper, but the sheet or the transport securing body may have at least one outer skin made of thermoplastic material, in particular polypropylene. Alternatively or additionally, the sheet or the transport securing body instead of cardboard or paper can be made entirely of thermoplastic material, in particular polypropylene.

The sheet or the transport securing body may have a different number of different recesses and / or slots depending on the respective equipment of the associated household refrigerator. The recesses and / or slots may be open-edged or have a closed contour. By means of the single fold, a V-shaped strip is formed from the flat sheet by folding. The V-shaped bar thus has two legs, each individually flat, i. has no further folds or needed. The V-shaped strip can have different opening angles in different designs. Thus, the V-shaped strip, which forms the transport safety body so far, have an obtuse angle, a right angle or an acute angle. In the embodiment with a right angle of the transport safety body can thus also be referred to as an L-shaped bar, which is considered a special form of a V-shaped bar. By the transport securing body is formed by means of a single fold to a cross-sectionally V-shaped bar with two legs, the transport lock body during assembly can be easily and quickly reshaped from its flat arch shape into a three-dimensional body, the only fold sufficiently high Stiffness and / or stability of the transport lock body generated.

The two legs can have folds opposite outer edges, over which the recesses, in particular slot-shaped recesses, in the legs are introduced, wherein the recesses are formed to secure the at least one shelf or the at least one door rack in the storage room in a transport locking position of the transport lock body.

In an exemplary embodiment, the recesses may be provided on the legs and designed to secure the at least one shelf in the storage space in a transport securing position of the transport securing body, wherein at least one opening extending beyond the fold may be provided, which has a contour edge which is in the transport securing position of the transport securing body surrounds the at least one door racks.

In an alternative embodiment, the recesses may be provided on the legs and formed in a transport securing position of the transport securing body to surround the at least one door racks, wherein an opening extending beyond the fold may be provided, which has a contour edge which in the transport securing position of Transport safety body secures the at least one shelf in the storage room. In the alternative embodiment, the transport safety body is thus arranged or fixed or clamped in a reversed position for the first-mentioned embodiment in the household refrigerator.

The provided on the legs of the cross-sectionally V-shaped transport securing body recesses can for example prevent tilting of the shelves and / or door racks particularly well or at least significantly reduced by holding due to the Schenkeiförmigen design of the shelf or door racks at least two widely spaced locations, so that with little force between the transport safety body and the shelf or the door rack of the shelf or door racks can be kept stable.

For transporting the household refrigeration appliance, all equipment parts, such as the shelves and / or door racks can be arranged in their later use positions and fixed there exactly by means of the transport lock body. The shelves are usually mounted on projecting strips or recessed grooves on opposite inner walls of the inner container. To fix the one or more shelves, the transport safety body on slot-shaped recesses, in which front edge portions of the shelves in the transport locking position of the transport lock body dive. The slot-shaped recesses fix the shelves at defined fixed distances from each other, so that, for example, rattling of the shelves in the grooves of the inner container or on the strips of the inner container is prevented. Also, the shelves can no longer move in the extension direction by the presence of the transport lock body and encounter unfavorably against the inside of the door panel. The V-shaped strip is positioned in the transport locking position of the transport lock body in the household refrigerator, that the slotted legs of the V-shaped bar each intervene between two shelves or each shelf, possibly even a single shelf by means of the slot-shaped recesses of the legs is encompassed. In this case, the V-shaped strip in the transport locking position is also positioned such that the wedge-shaped outer tip assigns the V-shaped strip to the inside of the door leaf, in particular on the inside of the door leaf or on the one door rack or the plurality of door cabinets. By the transport securing body is formed by means of a single fold to a cross-sectionally V-shaped bar with two legs, a sufficiently high stability and rigidity of the transport securing body is achieved, without causing unnecessary weakening of the transport securing body, as would be the case additional additional folds would be provided. Grooving required in known cardboard boxes for the formation of crack-free foldings can be dispensed with further, that is to say, apart from an optional grooving of the only necessary fold, whereby the transport safety body is not weakened in its structure to that extent. If the sheet or the transport safety body is not formed of paper or cardboard, but of plastic, in particular polypropylene, grooving may possibly be dispensed with altogether, ie also for the only necessary fold. The transport securing body may have at least one opening extending beyond the fold, which has a contour edge, in particular a closed contour edge, which surrounds the at least one door rack or the at least one shelf in the transport securing position of the transport securing body.

By means of the at least one opening extending beyond the fold, in addition to the shelves, the one or more door racks can additionally be secured for transport. By the one or more openings extending over the fold, a securing device can be provided, which is able to encompass the door racks or the door racks. The one or more openings can be introduced in a simple manner by punching in the flat sheet, wherein in the reshaped shape of the transport lock body, the respective door racks embracing wedge structures are generated only through the openings. By these wedge structures which surround the respective door racks extend over the fold, a particularly high rigidity and stability of the transport securing body is achieved, so that the door racks can also be fixed particularly well on the inside of the door leaf for transport, i. be secured.

The transport securing body may have at least one fixing tab which is designed to fix the two legs of the bar formed along the fold at a fixed angle to one another.

The at least one fixing tab connects the one leg of the V-shaped transport securing body with the other leg at a distance from the fold, so that a certain angle of the V-shaped transport securing body is fixed. The fixing tab is formed by a portion of the sheet of the transport securing body and has a sufficient rigidity, so that a sufficiently high compressive force can be transmitted, which ensures a fixed distance of the two legs and thus the desired opening angle fixed.

The at least one fixing tab may have a fixed end portion connected to the one leg and a free end portion which is tongue-like-free through at least one release slot provided in the flat arch have, in a fixation position of the fixing tab, in which the transport locking body has the fixed angle, is positively and / or non-positively attached to the other leg.

The fixation tab may thus be formed in the manner of a rectangular strip having two opposite short outer contour edges and two opposite long outer contour edges. A short Außenkonturrand forms the fixed end portion and is so far integrally connected to the bow or goes into this arc. The other short outer contour edge forms the free end portion. The tongue-like release can be formed by the short outer contour edge, which represents the free end portion, and the two long outer contours.

In one embodiment, the free end portion of the fixation tab may have a tapered towards its front end contour, which is inserted in a fixing slot, in particular a fixing slot formed by the release slot in the fixation position of the fixing tab in particular non-positively.

By the free end portion of the fixation strap has a tapered towards its front end contour, this free end portion can be clamped in the fixation slot by the free end portion inserted so far into the fixation slot or pulled until it between the two opposite inner contour edges of the fixation slot pending. The farther the free end section, which has the contour tapering towards its front end, is inserted into the fixation slot, there is an increasingly wider section of the fixation strap in the opening region of the fixation slot. If this section has a width corresponding to the opening width of the fixing slot, the free end section of the fixing tab is clamped firmly in the fixing slot. Alternatively or in addition to such at least predominantly non-positive fixation, the fixing strap can also be fixed in a form-fitting manner. In another embodiment, therefore, the free end portion of the fixation tab may have a contour widening towards its front end, in particular an undercut contour, which in the fixation position has a fixation slot, in particular engages behind a fixing slot formed by the exemption slot.

In the case of a fixing tab having a contour widening towards its front end, the widening contour can be inserted behind a slot, a recess and / or opening in the leg of the V-shaped transport securing body opposite the fixing tab, the latter being directed towards its front end widening contour this slot, this recess and / or opening engages behind a form fit. The undercut contour can be formed by a paragraph or more paragraphs in the contour of the fixation tab. The undercut contour may in particular have a step, preferably a right-angled step. In the case of two opposite, in particular mirror-symmetrically arranged undercut contours or steps, for example, a T-shaped end of the free end portion of the fixing strap can be formed. In the embodiment as a contour that widens toward its front end, the undercut contour can thus be formed by an end of the free end section of the fixing tab which is T-shaped in contour.

The T-shaped end can be inserted into a slot, a recess and / or opening in the opposite side of the fixing tab legs of the V-shaped transport securing body. In particular, it may be an open-edged recess on a free edge of the opposite leg, in which the T-shaped end is hooked. In all embodiments, the slot-shaped recess, which is formed in the transport securing position of the transport securing body to secure the at least one shelf in the storage room, optionally have at least one slot width of the recess to the outer edge of the leg towards expanding introduction bevel.

Due to the insertion bevel, the recess in the region of the outer edge of the leg has a greater width than in a middle and lower region of the slot-shaped recess. By such an introductory slope of the Transport safety body are brought without special adjustments in its transport locking position. In particular, tolerance deviations of the transport safety body and / or different positional situations of the shelves can be compensated. By attaching the transport securing body to the shelves they are aligned according to the position of the slot-shaped recess by means of the insertion bevels.

The insertion bevels may be provided on only one of the two opposite edges of the slot-shaped recess or on both opposite edges of the slot-shaped recess. The introduction bevels can widen an example rectangular slot in the region of the outer edge of the leg V-shaped.

Alternatively or in addition to an insertion bevel, the slot-shaped recess which is formed in the transport securing position of the transport securing body to secure at least one shelf in the storage room, have at least one narrowing the width of the slot-shaped recess constriction, which surrounds a front strip of the shelf in the transport locking position , In other words, in the bottom of the slot-shaped recess, the width of the recess can be extended with respect to a central portion.

The base of the slot-shaped recess may have an inner contour, which is adapted to a cross section of a decorative strip attached to the front edge of the shelf, in particular corresponds in its shape to the cross section of the decorative strip. In embodiments without decor strip, the bottom of the slot-shaped recess may have an inner contour which is adapted to the shape of the front edge of the shelf or corresponds to it.

In general, the flat sheet, from which the transport securing body is formed, may have an outer skin made of thermoplastic material, in particular polypropylene, and / or be manufactured entirely from thermoplastic material, in particular polypropylene. By the flat sheet, from which the transport securing body is formed, an outer skin made of thermoplastic material, in particular polypropylene and / or is made entirely of thermoplastic material, in particular polypropylene, the pieces of equipment, especially the shelves and door racks from damage, such as scratches protected become. It has been shown that cardboard or cardboard has a very rough surface, which can scratch the equipment parts, especially the shelves and door racks during transport due to recurring movements. Thermoplastic plastic, especially polypropylene is less rough and thus does not tend to damage the equipment, especially the shelves and door racks.
