DESCRIPTION

Gate hardware for a gate or a cabinet lid

The invention relates to a gate fitting for a gate of a piece of furniture, and the gate fitting has the following: a base element, a damper with a support element and a dampened mobile activator in front of it, as well as an arm swivel which is fixed in such a way that it can rotate between the opening position and a closing position in the base element and which rests in the opening position against the base element indirectly by means of the damper.

A gate fitting of this type is known from EP 1 713 966 B1. In this, a folding cover is provided, which is rotatably fixed with a first cover element about a first axis arranged horizontally on a body in the area of a roof. In addition, the folding cover comprises a second cover element that joins with the first cover element rotatably about a second axis that is arranged horizontally. The folding lid is adjustable between a closed position, in which the first cover element and the second cover element are arranged vertically one above the other in a common plane and close an opening of the body, and an opening position in the which the two stage elements bend up. A rotating arm of a gate fitting is fixed so that it can rotate in the second element of the lid, as well as in a base element of the gate fitting, which is fixed in the body. By means of a mechanical drive that is exerted on the rotating arm, the rotating arm is movable starting from an intermediate position or from a neutral position between the opening position and the closing position to adopt its opening position and its closing position. A shock absorber is attached to the base element that dampens the movement of the folding cover, both briefly before reaching the opening position, as well as the closing position. For this, in the closed position, the swivel arm is pushed against the shock absorber. In the opening position, a sliding plate of the mechanical drive is driven against the damper.

This gate fitting has a defined opening angle and a defined closing angle. In the folding lid, the lid elements are in the open position in a maximum upper position. Here, the cover elements partially protrude over the roof of the body. However, there are application cases in which a collision with the covers or other elements in the opening position has to be avoided. In order to take advantage of the same gate fitting for such application cases, the so-called opening angle delimiters are known which are configured as a stop and delimit the path of the gate ejido and the cover elements in the direction towards the position opening. In other words, the planned delimited opening position is then in a lower position than without the use of the opening angle delimiters. Known opening angle delimiters are configured as solid stops so that the damping elements eventually provided from the gate hardware no longer display an action since the gate fitting does not reach the originally intended opening position by construction, but rather it is stopped before this by means of the opening angle delimiters before the scope of action of the shock absorber is reached.

Another gate fitting is known, for example, by publication DE 10 2008 025 265 B4. This refers to a gate fitting for a folding lid that is arranged opening upwards and has a second cover element that is rotatably connected with the first cover element. The gate hardware is fixed on the body of a piece of furniture and has an articulated lever arrangement by means of which the first cover element is operated. The articulated lever arrangement comprises a rotating arm that is rotatably disposed in front of a base element of the gate fitting. In the rotating arm a shock absorber is fixed in which a support element of the shock absorber is fixedly connected with the rotating arm an actuator of the shock absorber is driven so that it can move in the support element. When the gate hardware is skipped in a closed position, the activator is driven against a stopper element and moves against a damping force of the damper such that the movement of the gate hardware and, therefore, of the gate foldable, cushion in the closed position.

The objective of the present invention is, therefore, to propose a gate fitting that guarantees a delimitation of the opening angle without, however, reducing the damping function by delimiting the opening angle.

The objective is achieved by means of a gate fitting for a gate of a piece of furniture, in which case the gate fitting has the following: a base element, a damper with a support element and a mobile activator, damped against it, as well as a rotating arm that is rotatably fixed between an opening position and a closing position in the base element and which is supported against the base element at least in the opening position indirectly by means of the damper; and an opening angle delimiter is provided that rests against the activator of the damper and the opening angle delimiter joins with the activator so that they can be released.

Therefore, at least in the opening position (respectively in the delimited closing position), the rotating arm is supported by means of the damper and the opening angle delimiter, in which case the opening angle delimiter is jointly adjustable with the activator so that a damping of the

the gate when using the opening angle delimiter.

Preferably, the shock absorber is a linear shock absorber, and the activator is driven in such a way that it can move linearly against the support element.

In order to form a unit capable of being assembled previously, the support element of the shock absorber can be fixed on the base element, in which case the rotating arm is propelled against the activator. Alternatively, the support element can be fixedly fixed on the rotating arm so that the damper rotates with the rotating arm. Here, briefly before reaching the opening position, the activator is pressed against stop surfaces in the body or in the base element.

The swivel arm can rest against the damper activator in the opening position indirectly by means of the opening angle delimiter. Since the rotating arm rests against the damper in the open position, the travel of the rotating arm can be delimited by the opening angle delimiter.

Additionally it can be provided that the opening angle delimiter is conducted linearly in the base element. For this purpose, the base element can have two perforated plates arranged parallel to each other, between which the swivel arm is laid so that it can rotate, in which case the perforated plates respectively have a guide groove, which are arranged parallel to each other, opposite each other, in which case the opening angle delimiter is led to the guide grooves.

Here, the guide grooves can be delimited respectively by a strut in the direction of an extended position of the activator so that the opening angle delimiter is securely fixed in the guide grooves. Therefore, it is also conceivable that the opening angle delimiter does not join with the activator but only presses against it. An involuntary separation of the opening angle delimiter from the guide grooves is prevented in this case by means of the struts so that the fixing of the opening angle delimiter is dispensable.

The support element can be fixed in the base element or in at least one of the perforated plates. Alternatively, it can also be provided that the support element is a component of at least one of the perforated plates. Preferably, the support element is formed from both perforated plates. For this purpose, one of the halves of the support element can be integrally a component of a perforated plate, mainly if the perforated plates are formed of injection molded plastic parts.

According to the invention, the opening angle delimiter is connected with the activator so that they can be separated, for example, by a fixing mechanism by which the opening angle delimiter is capable of being embedded with the activator.

In order not to allow the opening angle delimiter to manifest itself optically, it can be provided that it is completely housed between the perforated plates.

A preferred embodiment of a gate fitting according to the invention is explained below by means of the drawings.

The folding cover 7 comprises a first layer element 8 which is fixed in the area of the roof 2, so that it can rotate around a first axis arranged horizontally in the body 1. In addition, the folding cover 7 has a second element of cover 9 that joins with the first cover element 8 so that it can rotate about a second axis that is arranged horizontally. The folding cover 7 is adjustable between a closing position in which the first stage element 8 and the second stage element 9 are arranged vertically one above the other in a common plane and close the opening 6, and an opening position , as depicted in Figure 1.

On the side wall 3 of the body 1 a base element 12 of a gate fitting 11 is fixed, in which case in the base element 12 a rotating arm 10 is fixed so that it can rotate. The rotating arm 10 joins with the second cover element 9 so that they can rotate at a remote end of the gate fitting 11. In the gate fitting 11 there is a mechanical drive (not shown) that is configured in such a way that to the rotating arm 10, and with this to the folding cover 7, a force is applied from an intermediate position that is between the open position and the closed position, in the direction of the open position represented in Figure 1. In an area between an intermediate position of the gate fitting and the folding cover 7 and the closing position, force is applied to the folding cover 7 towards the closing position, so that the cover is maintained in the closed position. The mechanical drive may have a result package in a known manner that rests on one side against the base element and on the other side against a slide or a rotating lever. The slide or the rotating lever act in turn on a lever mechanism or an adjustment profile on the rotating arm so that a couple of forces are generated on the rotating arm.

In order for the movement of the folding cover 7 to be damped in the open position, a shock absorber 14 is provided which is not shown in Figure 1, which briefly before reaching the opening position of the folding cover 7 dampens or brakes the movement of the folding lid 7 until the full opening position is achieved.

In the opening position shown in Figure 1, the folding lid 7 with the measure H protrudes above the ceiling 2. However, if the application cases do not allow the folding lid to protrude above the ceiling 2, a opening angle delimitation. Figure 2 shows the gate fitting 11 and the folding lid 7 in a delimited opening position, in which case an opening angle delimiter is applied 13. The opening angle delimiter 13 serves as a stop that delimits the path of the rotating arm 10 in the direction towards the opening position so that the movement of the rotating arm 10 is limited before reaching the maximum possible opening position by construction, according to Figure 1. In this delimited opening position, the folding cover 7 does not protrude above the roof 2.

Figure 2 shows the gate fitting 11 in a sectional representation, so that the damper 14 used can be recognized. This has a support element 15 which is fixed in the base element 12 of the gate fitting 11. The damper 14 has an activator 16 that projects in the direction of the opening 6 and the folding cover 7, and this activator is movable linearly towards the support element 15. On the activator 16 the opening angle delimiter 13 rests, against which in turn the rotating arm 10 rests in its delimited opening position according to Figure 2. When using the damper 14 Without opening angle delimiter 13, as shown in Figure 1, the rotating arm 10 in the open position rests directly against the activator 16 and a stop surface 22 on the base element 12.

Figures 3 and 4 show a cut of the gate hardware 11 in the area of the damper 14, in which case Figure 3 shows the position of the rotating arm 10 briefly before reaching the delimited opening position and Figure 4 shows the rotating arm 10 in the delimited opening position.

It can be recognized that the damper 14 has a support element 15 which joins with the base element 12 of the gate fitting 11. The support element 15 has a shell-shaped configuration and houses a damper, for example, in the form of a compressed gas damper which has a cylinder 17 representing the activator 16 and a piston 18 that rests against the support element 15 in the housing-shaped support element 15. The cylinder 17 is maintained in such a way that it can move linearly in the support element 15. The cylinder 17 or the activator 16 can be moved from a fully extended position, shown in Figure 3, to a contracted position represented in the Figure Four.

The opening angle delimiter 13 is detachably fixed with the activator 16. This delimiter has a contact surface 20 against which a backing surface 19 of the rotating arm 10 is driven. Starting from the closing position to the position shown. in Figure 3, the backing surface 19 does not come into contact with the contact surface 20. Only from the position shown in Figure 3 briefly before reaching the open (delimited) position, the backing surface 19 of the rotating arm 10 is pushed against the contact surface 20 and is introduced by moving the activator 16 in the support element 15 by means of the opening angle delimiter 13, whereby the movement of the rotating arm 10 is damped until reaching the delimited opening position according to Figure 4.

In the position shown in Figure 3, there is a stop surface 21, facing away from the contact surface 20, of the opening angle delimiter 13 distanced from a stop surface 22 of the base element 12. As soon as it is reached the delimited opening position according to Figure 4, the abutment surface 21 of the opening angle delimiter 13 rests against the abutment surface 22 of the base element 12, such that the turning path of the swivel arm 10.

By using the gate hardware 11 without opening angle delimiter 13, the backing surface 19 of the rotating arm 10 would be propelled directly against the activator 16 and would move it towards the support element 15, in which case this would happen in a position that It is above the delimited opening position shown in Figure 4. In the opening position without using the opening angle delimiter 13, the surface of

backrest 19 would collide with the abutment surface 22 of the base element 12 to delimit the turning path.

The base element 12 comprises a first perforated plate 23, which is shown in Figure 4, which is arranged parallel to the side wall 3 and is fitted flatly thereto, and joins it. On the side of the gate hardware 11 that is facing away from the first perforated plate 23 there is provided a second perforated plate 24, shown in Figure 1, which closes the gate hardware. This second perforated plate 24 is arranged in parallel with the first perforated plate 23 to visualize the individual parts of the damper 14, not shown in Figures 2, 3, 4 and 5.

A horizontal guide groove 25 is provided on the first perforated plate 23. The second perforated plate 24 has a guide groove (not shown) parallel to it and faces the guide groove 25 of the first perforated plate 23. The opening angle delimiter 13 has both sides in the direction of the two perforated plates 23, 24, respectively, a guide projection 26 with which the opening angle delimiter 13 is guided linearly in the guide grooves 25 in an adjustable manner. The guide grooves 25 are respectively delimited by a strut 27 towards the opening 6 so that the opening angle delimiter 13 cannot involuntarily exit the guide grooves 25. For this it is required to disassemble one of the perforated plates 23, 24 or , if the perforated plates 23, 24 are manufactured from a plastic, it is required to separate by pressing the perforated plates 23, 24. The opening angle delimiter 13 can be configured as a ramp on both sides, that is in the direction of the damper 14 and in the direction of the struts 27. Therefore, for installation, the opening angle delimiter 13 can be pressed against the struts 27 from the outside, in which case the ramps rise towards the guide projections 26 so that the perforated plates 23 , 24 separate by pressing. In addition, when the opening angle delimiter 13 is removed from the guide grooves 25, a ramp-like increase towards the guide projections 26 ensures that the perforated plates 23, 24 are separated by pressing and the opening angle delimiter 13 can be removed without tools
