Description

TECHNICAL AREA

The invention relates to a braked bearing, in particular for a piece of furniture, and a piece of furniture, in particular a folding table.

STATE OF THE ART

Braked bearings for damping pivotal or rotational movement between two components are known to the applicant internally. Such a braked bearing has, for example, a bush which rotatably receives a journal. The diameter of the pin is dimensioned such that it is in frictional contact with the socket. During a rotary movement of the pin in the bush, this is braked due to the friction.

In the approach described above, it has proved to be disadvantageous that the generated friction and thus also the corresponding braking force, which act on the pin when turning thereof, are constant. This is unfavorable especially with regard to a table top of a folding table, which is to be pivoted from its vertical position to its horizontal position and thereby braked. For here is to the end of the pivoting movement of the table top maximum braking effect can be achieved to ensure the most noiseless attack the table top on a table frame of the folding table.

PRESENTATION OF THE INVENTION

This object is achieved by a braked bearing with the features of claim 1 and by a piece of furniture with the features of claim 9.

Accordingly, it is provided:
A braked bearing, in particular for a piece of furniture, with a pin; a bush which rotatably receives the pin; and with a compressible brake element, which is rotatably connected to the pin; wherein the pin and bushing have a first position in which the brake element is substantially relaxed and a second position relative to each other in which the brake element bears substantially compressed against the bushing for generating a frictional force.

Furthermore, a piece of furniture, in particular a folding table, which has the bearing according to the invention.

The idea underlying the present invention is to provide a compressible brake element which is non-rotatably connected to a pin of the bearing, wherein the pin and a bush of the bearing a first position in which the brake element is substantially relaxed, and a second position have to each other, in which the brake element is applied substantially compressed against the bushing for generating a frictional force. Thus, the braking force generated by the bearing or the braking torque generated is not constant, but depending on the position of the pin and the sleeve to each other. This makes it possible that in a folding table, which has the bearing, the table top gently and thus quietly abuts a stop on a table frame of the folding table when the table top arrives in its horizontal position.

From the dependent claims, advantageous embodiments of the present invention.

From "substantially relaxed" should also include a state of the brake element, in which this rests against the bush, but does not generate significant frictional force. Furthermore, a state of the brake element is to be encompassed by "substantially compressed" in which this is only partially compressed, but generates a significant frictional force.

According to one embodiment of the bearing according to the invention, the pin has a recess on its periphery, which receives the brake element. Thereby, the brake element can be easily and at least positively held on the pin to provide the rotationally fixed connection between the brake element and the pin.

According to a further embodiment of the bearing according to the invention, the recess extends along the central axis of the pin in this. As a result, a comparatively large contact area between the brake element and the bushing can be provided. This in turn has a positive effect on the generated frictional force or the braking torque that can be generated by the bearing.

According to a further embodiment of the bearing according to the invention, the recess is formed as a relative to the central axis of the pin eccentric bore. Such a recess can be easily generated.

According to a further embodiment of the bearing according to the invention, the bushing has a recess in which the brake element is arranged in the first position. The recess grants the brake element so room, so that this can relax.

According to a further embodiment of the bearing according to the invention, the bushing has a sliding surface which adjoins the recess and supports the journal, the braking element in the second position being compressed against the sliding surface. If the brake element moves along the sliding surface into the recess (by turning the pin and the bushing relative to each other between their first and second position), the frictional force changes from maximum (braking element in contact with the sliding surface) to minimum or zero ( Brake element is relaxed and arranged in the recess).

According to a further embodiment of the bearing according to the invention, the sliding surface and the recess formed as seen along the central axis of the pin in about a pear shape. The shape of the pear can be geometrically described as follows: The sliding surface, as viewed along the central axis of the peg, has a first pitch circle shape with a first diameter. The recess has, seen in the longitudinal direction of the pin, a second partial circular shape with a second diameter. The first and the second pitch circle each at their ends by means of a rounded transition to each other. The second diameter is formed smaller than the first diameter.

According to a further embodiment of the bearing according to the invention, the brake element is designed as a solid cylinder and / or polyurethane. Such a braking element is easy to manufacture and install. In addition, such a braking element generates the desired frictional force and thus the desired braking torque.

According to one embodiment of the folding table according to the invention a table top is pivotally mounted by means of at least one bearing on a table frame between a vertical position and a horizontal position thereof, wherein the pin and the socket in the vertical position of the table top in its first position and in the horizontal position of the table top in its second position to each other, so that a pivoting of the table top is braked from its vertical position to its horizontal position. This can be achieved that the table top passes almost noiselessly in its horizontal position.

DESCRIPTION OF EMBODIMENTS

1 shows in perspective a folding table 1 according to an embodiment of the present invention. The folding table 1 is with respect to a line of symmetry 2 formed symmetrically.

The folding table 1 has a table top 3 and a table frame 4 on. The tabletop 3 is on the table frame 4 by means of two camps 5 hinged pivotally. The left bearing 5 is in 1 partly to see and in the 2 - 6 shown in more detail. The right camp 5 is outside the range shown and is identical to the left bearing 5 built up.

In the 1 shown position of the table top 3 corresponds to an intermediate position thereof between its vertical position and its horizontal position. On the other hand shows 4 the table top 3 in their horizontal position while 6 the table top 3 in its vertical position.

The warehouse 5 slows down a pivoting of the table top 3 if this, as indicated by the arrow in 1 indicated, is pivoted from its horizontal position in its vertical adjustment to a hitting the table top 3 on the table frame 4 provide as quiet as possible. The pivoting of the table top 3 from her horizontal in their vertical position is merely triggered by an operator, whereupon the tabletop 3 independently pivoted under the action of gravity from its then slightly deflected position in its horizontal position.

Based on 3 can be seen that the pin 12 on its underside (facing the ground) a recess 16 having. The recess 16 takes the brake element 15 on, with the latter in 3 not shown. The recess 16 extends along a pin central axis 17 ,

For example, the recess 16 designed as a bore. The hole 16 is along the pin central axis 17 Seen eccentric with respect to these arranged. This results in a substantially crescent-shaped cross-section 21 for the journal 12 , Is the brake element 15 So in the recess 16 arranged, so this extends radially, that is perpendicular to the pin central axis 17 , over the circumference 22 of the pin 12 out.

4 shows the camp 5 out 2 together with the other components shown there in the assembled state in a sectional view CC 5 , 5 again shows a sectional view DD 4 ,

In the 2 and 4 is the embodiment of the socket 13 to recognize. The socket 13 has a recess 23 which is attached to a sliding surface 24 the socket 13 followed. The recess 23 serves to the braking element 15 as will be explained in more detail below, while the sliding surface 24 the pin 12 encompasses the tabletop 3 is rotatably mounted on this. The recess 23 and the sliding surface 24 form along the pin central axis 17 seen, see 4 , in about a pear shape.

6 corresponds to the illustration 4 However, the tabletop is in 6 arranged in their vertical position.

The pin 12 and the socket 13 have a first position to each other, in which the brake element 15 is relaxed. In this first position, the brake element engages 15 into the recess 23 one or lies opposite this, so that the brake element 15 essentially expand at will. This first position of the pin 12 and the socket 13 corresponds to the vertical position of the table top 3 ,

Will the table top 3 now from the operator person from their in 6 Slightly deflected shown vertical position, gravity causes a torque around the pin central axis 17 is produced. This torque causes the sliding surface 24 increasingly with the braking element 15 comes into contact with the brake element 15 increasingly compressed. From this compression results in a frictional force between the friction element 15 and the socket 13 or its inner surface 25 , please refer 6 , The frictional force in turn requires a torque counteracting the gravitational force about the pivot axis 17 so that the pivoting movement of the tabletop 3 is braked from its vertical position to its horizontal position. In the horizontal position of the tabletop 3 , please refer 4 , are the pin 12 and the socket 13 in a second position to each other, in which the brake element 15 compressed against the socket 13 or its inner surface 25 is applied. In the horizontal position of the tabletop 3 is that of the brake element 15 generated friction force maximum, so that the table top 3 almost noiseless against attacks 26 , please refer 1 and 2 , the table frame 4 strikes.

Although the invention has been described herein with reference to preferred embodiments, it is by no means limited thereto, but modifiable in many ways. In particular, it should be noted that "a" in this case excludes no variety.

Of course, the bearing does not need to rotatably connect two components of a folding table together. Rather, the bearing can connect any components of a piece of furniture rotatably with each other.
