Description

The The invention relates to a retractable handle device with a handle bar and with bar holders, which with the handlebar and a handle mount are connected. Furthermore, the invention relates to a door for a domestic appliance with such a handle device.

at Built-in stoves and ovens are doors for closing a feed opening of a cooking chamber known to which outside, a handle is arranged. In this regard, Fixed handles are known which over the front surface survive the door permanently. Can do that then easily get clothes from operators and / or you can trust it. In addition, it is Such a configuration is relatively space-consuming.

From the DE 23 64 647 is a oven door known, which has a pivotable door handle. This is pivotable about an axis of rotation and can thus be folded or sunk only by a pivoting movement to the outside. Therefore, a relatively large amount of space is required to enable this movement, and even when it is lowered a relatively large amount of space for the handles is to be kept ready.

From the DE 38 38 917 A1 is a closure device for the door of a hot air steam oven known. In an alternative embodiment it is provided that a handle device for the door has a handle bar and thus fixed and immovably connected holder for this handle bar, wherein the handle device can be pushed in a linear movement in the door or pulled out of this. In the retracted state, the handle device is recessed substantially in the door. Also for this embodiment, a relatively large amount of space is required. In addition, the accessibility is limited, so that the removal of the recessed handle can be done only very expensive and laborious.

These Task is by a gripping device, which features according to Claim 1, solved. Furthermore this task becomes even through a door for a household appliance, which has the features of claim 14 solved.

A Retractable handle device according to the invention includes a handlebar and rod holder for holding this handlebar. The pole holders are with the handle bar and a handle holder connected. The rod holders are relatively movable to the handlebar and arranged relatively movable to the handle bracket and on a Rod holder is arranged at least one sliding block, which for guiding the movement of a bar holder in a guideway a grip holder engages. Through this embodiment of the retractable Gripping device, the sinking or pulling out little effort and done reliably. An obstruction, jamming or Lashing can be avoided. In addition, can a very component-minimized by this embodiment of the handle device Be provided embodiment, which in addition also compact and space-saving can be realized.

Preferably the grip holder has a slot-like receiving space, in which the bar holders extend. For one thing As a result, components of the handle device wear and protected against damage or other interference can be arranged and moreover, the space requirement the grip device can be reduced again.

Preferably has a rod holder at its top at least two spaced apart to each other arranged upper sliding blocks. By the majority of sliding blocks can guide the rod holder improved and unstable brackets and an unstable guide can be avoided. This can also reduce the wear become.

Preferably are at a top cover of the receiving space two separate upper guideways trained and in each case an upper sliding block engages in one of the upper guideways. Through this at least duality of two guideways and Two sliding blocks can be the guide curve or the guideway be optimized. This can be as space-saving as possible Depression and extension of the handle bar and on the other hand in terms of least possible shift in one direction parallel to the axis of the gripping device. The entire movement when sinking or retracting can thus in one possible small room done.

Preferably a first upper sliding block is arranged at a front end of the rod holder and a second upper sliding block is in the longitudinal direction of the rod holder considered approximately in the middle of the rod holder positioned at the top. Due to the relatively large Spacing of the sliding blocks can occur Situation forces are kept as small as possible.

Preferably It is envisaged that a rod holder on a bottom at least having two spaced apart lower sliding blocks. It is particularly preferred that both at the top as well as at the bottom at least one sliding block, preferably two sliding blocks are arranged in each case. The advance mentioned advantages are thereby further favored.

Preferably are at a lower cover of the receiving space two separate lower guideways trained and in each case a lower sliding block engages in one of the lower guideways. In vertical Considered direction is thus the rod holder with several sliding blocks both upwards and downwards in guideways led, so that the sinking movement or. the outward movement particularly advantageous in terms of low wear and safe and reliable guidance without splaying and jamming and without tilting up or down or to the side.

Especially It is envisaged that a first lower sliding block at a front End of the rod holder is arranged on the underside and a second lower sliding block in the longitudinal direction of Bar holder looks approximately at the center of the bottom of the bar holder is arranged.

Preferably is provided that the upper and lower sliding blocks correspondingly symmetrical positions at the top and bottom are arranged.

It is preferably provided that a guideway, in particular all guideways, at least in some areas are formed curved. It is preferably provided that all guideways over their entire length are formed curved and preferably the same Have direction of curvature. Advantageously, it is provided that at each two guideways per rod holder in the upper cover and the lower cover the corresponding ones Guideways in a cover in the longitudinal direction of Handle holder considered partially overlapping arranged are. However, it is essential that the guideways do not touch each other and thus over the whole Length contactless and arranged separately from each other are formed.

preferably, a rod holder has an axis of rotation which is perpendicular to the Versenkrichtung oriented and arranged fixed to the handle mount is. In addition to the sliding blocks and the preferably several guideways per rod holder is thus additional arranged the stationary axis of rotation. These can be the rod holder then in his sinking or in his movement out rotate.

Preferably a rod holder has an axis of rotation which is perpendicular to the Versenkrichtung oriented and arranged fixed to the handlebar is. In particular, it is thus provided that the rod holder fixed Has axes of rotation about which it can rotate and which at different Components are arranged stationary. On the one hand, this is the Stability increases and the desired Movement stabilized and the guiding movement of the sliding blocks improved in the guideways.

Preferably is provided that the rod holder with a coupling mechanism are connected to the motion synchronization of the two rod holder. In particular, such a coupling mechanism has two push rods on, which are each connected to a rod holder and over a gear device, which associated with the coupling mechanism is, are coupled. By means of these push rods it is thus possible to synchronize the two rod holders. This is special advantageous because the handle bar preferably parallel to the front the grip device enters, even if it operates off-center becomes. The synchronization is preferably via a Gear of the gear device, which at the same time for damping can serve when extending the handlebar. Preferably, this is the Gear with a damping device, in particular a Rotary damper, connected. This drives the unlocked handle or the handle bar slowly from the depressed End position or the rest position in the extended position or the operating position.

Preferably the retractable handle device has a locking device for locking the recessed position of the handle bar, wherein the locking device comprises a sliding block, which in a slide track, in particular a closed heart curve shape having slide track, the locking device engages.

Further Features of the invention will become apparent from the claims, the figures and the description of the figures. The above in the description mentioned features and feature combinations and the following mentioned in the description of the figures and / or in the figures alone shown features and feature combinations are not only in the each specified combination, but also in other combinations or used alone without the scope of the invention to leave.

One Embodiment of the invention will be described below schematic drawings explained in more detail. It demonstrate:

1 a schematic perspective view of a household appliance with a door of a handle arranged thereon;

2 a perspective view of the handle device in a first operating position; and

3a to 3c Plan view of the handle device according to 2 in three different operating positions.

In The figures are the same or functionally identical elements with the provided the same reference numerals.

In 1 is shown in a schematic representation of a domestic appliance, which as an oven 1 is trained. The oven 1 includes a cooking space 3 with a front loading opening 4 which through a door 2 is closable. The door 2 is pivotable in its lower side via a horizontally and parallel to the oven base extending axis of rotation. At the door 2 is outside a handle device 5 , which is designed as a retractable handle device arranged. The grip device 5 can be about an axis parallel to the pivot axis of the door 2 be pivoted. In particular, this can be a handle bar of the handle device 5 be pivoted accordingly. When folding down pen the door 2 In the at least partially open position can thus be achieved that the handle bar of the handle device 5 always facing the user and performs a corresponding pivoting movement about the axis.

In 2 is a perspective view of the handle device 5 shown. In this case, an operating position is shown in which a handle bar 6 is shown in the fully extended state. The retractable handle device 5 includes next to the handlebar 6 a handle holder 7 At the front of the front plate-like part of the door 2 is arranged. The handle holder 7 can also be integral in this front panel of the door 2 be arranged or even be part of this front panel.

The grip device 5 also includes two bar holders 8th and 9 , which are relatively movable to the handlebar 6 and relatively movable to the handle bracket 7 are arranged. The rod holders 8th and 9 are designed as levers to the sinking movement of the handlebar 6 and / or the outward movement of this handlebar 6 to ensure.

The handle holder 7 has a recording room 10 on, in which the bar holders 8th and 9 hineinerstrecken. As in 2 through the partially transparent representation of the handle holder 7 it can be seen, the recording room 10 upwards through an upper cover 11 and down through a lower cover 12 limited. The covers 11 and 12 are quasi designed as plate-like strips.

Between these covers 11 and 12 The bar holders extend 8th and 9 in the recording room 10 into it. The pole holder 11 is with a first axis of rotation 13 connected, which is fixed to the handle bracket 7 is arranged.

The handlebar 6 can perform their movement linear in the y-direction and sunk or driven out. The rod holders 8th and 9 point to the reception room 10 skillful surveys 13 and 15 on.

As already too 1 the handle bar can be addressed 6 or the entire grip device 5 also perform a pivoting movement about the x-axis.

Furthermore, the pole holder includes 8th a rotation axis 14 around which he can perform a rotary motion. The rotation axis 14 is fixed to the handlebar 6 positioned. In an analogous manner, the second rod holder 9 a rotation axis 16 on. On a top 17 of the first pole holder 8th are two separate and spaced from each other Kulisssensteine 18 and 19 arranged. The sliding stones 18 and 19 are in those part of the pole holder 8th on its top 17 arranged, which is in the receiving space 10 extends.

In a corresponding symmetrical arrangement are on a bottom of the rod holder 8th which of the top 17 is opposite, also arranged two sliding blocks, not shown. The at the bottom of the pole holder 8th arranged sliding blocks are arranged at the positions where the sliding blocks 18 and 19 at the top 17 are positioned.

In the top cover 11 are two guideways 20 and 21 arranged. Both guideways 20 and 21 are curved over their entire length and overlap in the x-direction at least partially. The guideways 20 and 21 do not touch and do not cross. The first sliding block 18 at the top 17 grabs the first guideway 20 one, with the second sliding block 19 at the top 17 in the second guideway 21 intervenes. In accordance symmetrically way are in the lower cover 12 also two slide tracks 22 and 23 incorporated, which in a vertical view and thus when viewed in the z-direction substantially congruent with the guideways 20 and 21 in the top cover 11 are arranged. The at the bottom of the pole holder 8th arranged sliding blocks each engage in one of the guideways 22 and 23 one. In a similar way are the sliding blocks 24 and 25 on a top 26 of the pole holder 9 educated. The sliding block 25 engages in a guideway 27 one, with the sliding block 24 in another guideway 28 intervenes. The guideways 27 and 28 are symmetrical to the guideways 20 and 21 along a y-direction through the handle device 5 centrally extending symmetry axis. In an analogous way are on a bottom 29 of the pole holder 9 also arranged two sliding blocks, which at the opposite position to the sliding blocks 24 and 25 are positioned. The at the bottom 29 arranged sliding blocks also engage in guideways 30 and 31 one, these guideways 30 and 31 again congruent under the guideways 27 and 28 in the lower cover 12 are formed.

In the slot-like recording room 10 is also a coupling mechanism 32 arranged. The coupling mechanism 32 includes a first push rod 33 , which with the first rod holder 8th connected is. The first push rod 33 points to the bar holder 8th opposite end of a tooth area 34 on which one with a gear 37 In addition, the coupling mechanism points 32 a second push rod 35 on which with the second rod holder 9 connected is. At that the bar holder 9 opposite end has the second push rod 35 a tooth area 36 on, which also with the gear 37 combs. Through this coupling mechanism 32 can the movement of the rod holder 8th and 9 be synchronized. The gear 37 is also equipped with a damping device 38 , which is preferably a rotary damper, connected, so that the movement is damped. Adjacent to the gear 37 and to the tooth area 34 a component is a locking device 39 arranged. The locking device 39 used to lock the rest position of the handlebar 6 and thus the sunk position. The locking device 39 has a component 40 on which in the handle bracket 7 is fixed in place and a heart-shaped slide track 41 ( 3a and 3b and 3c ). In this slide track 41 engages in the locked state a sliding block 42 one which is on the handlebar 6 is arranged.

The handlebar 6 is on her grip bracket 7 preferably formed hollow side facing. This can be in the rest position of the handlebar 6 and thus in the lowered state, the front of the handlebar 6 flush with the front of the handle mount 7 be arranged. In this lowered state of the handlebar 6 then extend the top cover 11 and the bottom cover 12 in this cavity of the handlebar 6 into it. Not only because of this can a particularly space-minimized and compact concept of the retractable handle device 5 be enabled.

In the 3a to 3c are plan views of the handle device 5 shown in different operating positions.

So shows 3a a plan view of the fully extended position of the handlebar 6 , as shown in perspective already in 2 is shown.

In 3a are also two leg springs 43 and 44 shown which in the area of the second axes of rotation 14 and 16 the pole holder 8th and 9 are arranged. About these thigh springs 43 and 44 can the handlebar 6 be pressed into the operating position. In the resting position of the handlebar 6 this is held by the already explained locking mechanism.

The per rod holder 8th respectively. 9 four guideways ensure that the rod holder 8th and 9 do not tip over and be guided stably. In addition, the sliding blocks can ensure by their relatively widely spaced positioning that the bearing forces that remain as small as possible.

In 3b is shown an operating position where the handlebar 6 between the rest position and the extended operating position is shown. It can be seen how the rod holders 8th and 9 move and how they are guided by the shaping of the guideways and the rotation about the two axes of rotation.

Through this overall mechanism can be during the movement of the handlebar 6 a movement can be achieved parallel to the front, even if on the handlebar 6 not centered and thus pressed off-center. Both the retraction and the extension is thus preferably linear in the y-direction.

In 3c is the rest position and thus the fully sunken position of the handlebar 6 shown. The above-mentioned flush positioning of the front side of the handlebar 6 with the front of the handle bracket 7 is recognizable. In addition, it is shown that the top cover 11 and the bottom cover 12 in the cavity of the handlebar 6 protrude.
