Technical field

The present invention relates to a kind of cooling device, have: the cooling chamber that is used for article to be cooled; The housing that holds described cooling chamber at least in part; At least one is used for entering the door of cooling chamber, and described door is arranged on the shell nozzle place of described housing, can be with respect to described housing motion; And, be arranged on the door fixture between described door and the described housing, described door fixture has the possess turning rod device for opening of (Kipphebel), and described device for opening is used for making described door to move to open position around the upset axis of level particularly from the closed position.

Background technology

In order to enter the cooling chamber that is closed by door seal of cooling device, be well known that the door that has various door fixtures, such door has been realized moving to open position from the closed position by device for opening.So, for example by DE 140 1 078 A1 known a kind of fixture, described fixture is fixed on door on the housing movingly by turning device.For this reason, the side direction of door is provided with two turning rods, in order to door can be overturn straight up in its motion.Although this door fixture has realized entering without barrier the cooling chamber of cooling device, but show: making demands before on the static(al) that switching mechanism is proposed to improve unfriendly, this turning device only can be suitable for conditionally, and this is because the door of upset can be made a response sensitively for the load force that causes because of upset thus.This switching mechanism can not guarantee the particularly desired long life in commercial cooling device.

Based on this reason, the door fixture (US 4 369 632) of the device for opening with alternative is disclosed, such door fixture for example has the pivoting device of the pivot axis that possesses vertical distribution.And contrast ground with the door fixture with turning device, this the service life that fixture can be guaranteed more to grow, this is because the parts of described device for opening also have door all not bear high relatively load when opening, but the disadvantage of this door fixture is, when opening, the door fixture protrudes from cooling device, and then has limited range of movement in cooling device.This door fixture can not guarantee clog-free entering, and this has caused inconvenience.

Summary of the invention

Thereby task of the present invention is that the cooling device so described type of structure beginning, that have movable door namely, not only can guarantee the high stability of a fixture with simple frame mode, and can guarantee to enter without barrier cooling chamber.

The present invention solves described task as follows, namely, the door fixture have be connected with turning rod, particularly receive support on the described turning rod, at least one parts of other device for opening of the described door of described rack bearing fixture are used so that door moves to the open position different with the open position of another this device for opening from the closed position.

If the door fixture has other device for opening, with so that door moves to the open position different with the open position of another this device for opening from the closed position, feasiblely according to the present invention so be, according to plain mode a kind of stable turning device is set, this be because: namely, can be accustomed to according to the user, adjust average two kinds of application that enter the uniform balance of selection scheme, just turning device can be set thereby need not special additional structure measure.And especially, when the door fixture has the support (at least one parts of other device for opening of this this fixture of rack bearing) that is connected with turning rod, can increase the service life.The load that causes because of upset of door can be shared (abtragen) like this to support, and this can improve the bearing capacity of door, particularly and then can improve the stability of a fixture.If support is received on the turning rod, so just obtain simple structural relation.So, contrasting ground with prior art, the present invention has not only guaranteed the service life that cooling device is higher, and alternatively or has first and foremost guaranteed to enter without barrier cooling device equally.

Especially, if a door fixture has support and support is arranged in such a way with respect to door, that is, and at door during around the upset axial-movement, support is responsible for power is shared on the turning rod by support, then door and/or the load that can be alleviated the power that causes because of upset of other device for opening.Causing the deformation force of upset can share to fall so simply, and for door and other device for opening, this makes demands before can reducing structure.Therefore, with respect to prior art, also can overturn even have door or the glass door of glass face, this particularly is favourable for operation ease, and this is because can see the article of cooling chamber before opening door.In addition, utilize support by reducing the danger of door or the fracture of door fixture, the security that can improve a fixture.Therefore, support can arrange with respect to door like this that namely, this support has also been realized power transmission connection (Kraftverbindung) except these other device for opening when door overturns, to allow to alleviating load force for the better door through upset.This support is preferred for supporting at least in part the door through upset.

Self-evident ground, turning rod always is not used as the linear pattern bar, turning rod fully can be configured to common type body, this can construct various process.

If support has Support frame, so not only realized being used for the structure of the load born of other opening mechanisms, but also advantageously this framework has been used as the support that can bear load.In addition, this framework for example can alleviate load through the door of upset in all sides, and this particularly can realize high relatively security, has door or glass door impaired of glass face with antagonism.A kind of simple structure situation is that turning rod is configured to common member with propping up.

A kind of simple structure of slippage guiding piece is closed and is tied up to support and have under the situation of horizontal guide portion of slippage guiding piece and realize, so this is because this support can be used for being configured to other device for opening of slippage guiding piece in structure aspects.

Described other device for opening are constructed to pivoting device, described pivoting device comprises the pivot bearings that is fixed on the support, described pivot bearings has and favours the pivot axis that described upset axis, particularly normal direction distribute in described upset axis ground, so can rely on a kind of inexpensive door suspension elements of door ground realization.

In order to avoid through the door of upset not controlled pivot taking place, can be set to: the support that is arranged on the reveal of cooling chamber has defined described range of pivot.Thus, can improve the security of a fixture simply, this is because under the situation of door through overturning, door lies on the support by the mode that defines with backstop, thereby and unexpected pivoting action can not occur again when turnover door.
