Description

The invention relates to a dismountable or foldable grandstand seat which can be fastened to a floor and has a standing platform part to which at least one seat part is fastened with at least one backrest pivotally arranged thereon, wherein the standing platform part is pivotably arranged on at least one post-shaped element by means of a first articulation is, and the post-shaped element is pivotally connected at its end remote from the floor pedestal part to the ground.

Such a grandstand seat is from the DE 10 2010 013 121 B3 known and can be folded in such a way that the seat part is arranged with the backrest laid on it in the folded state below the standing platform part, so that the standing platform part can be entered by a person. In the unfolded state is the floor platform part below the seat part. This is achieved in that the standing platform part is pivotally mounted on a support piece, so that by a pivoting movement, a reversal of the order of the standing platform part and the seat part in the vertical direction can be achieved. In other words, if the seat part before the pivoting movement is above the floor platform, it is located after the pivoting movement below the floor platform.

In the known grandstand seat Stehpodestteil is pivotally mounted with its attached seat part to a post-shaped member which is pivotally connected at its end remote from the floor platform part with the ground. This ensures that the height at which the seat part is in the unfolded state of the seat above the ground depends on the length of the post-shaped element. To change the height at which the seat part is located above the ground, therefore, only the length of the be changed post-shaped element. Thus, the seat can be easily adapted, for example, to different step heights of a grandstand.

Furthermore, it is possible to collapse or unfold the grandstand seat without the horizontal position of the seat part thereby substantially changed. In other words, the seat part is located after the unfolding of the tribune seat in the horizontal direction almost unchanged at the point where it is in the folded state of the grandstand seat. Only a slight displacement of the seat part in the backrest facing away from the horizontal direction is present. As a result, the seat can be used for example to build a grandstand, the steps have a relatively small depth.

Although the prior art grandstand seat proves to be advantageous in practice, it still has disadvantages. It may happen that differences in height between the floor platform parts or the seat parts of adjacent grandstand seats occur due to manufacturing and / or assembly tolerances and / or due to different weight of the grandstand seat user. If several grandstand seats side by side in a row are used as a pedestal, this may result in steps or paragraphs at the transition points between the grandstand seats, where the users of the grandstand seats could stumble. If the grandstand seats serve as seats, located in a gap between the seat parts adjacent grandstand seats garment pieces of the user can be trapped.

The object of the invention is therefore to provide a grandstand seat of the type mentioned, in which these disadvantages are avoided.

The solution of this problem arises from the features of the characterizing part of claim 1. Advantageous developments of the invention will become apparent from the dependent claims.

According to the invention, an openable or foldable grandstand seat, which is fastened to a floor and having a standing platform, on which a seat part is fixed with a backrest pivotally mounted thereto, wherein the floor platform is pivotally mounted on at least one post-shaped member by means of a first joint , and the post-shaped element is pivotally connected at its end facing away from the floor platform part to the ground, characterized in that arranged laterally on Stehpodestteil a radially spaced from a pivot axis of the first hinge locking element for releasably connecting with a mating receptacle of a standing platform part of a first adjacent grandstand seat is that on the opposite side of the locking element of the standing platform part a matching to a corresponding locking element of a second adjacent grandstand seat receptacle is arranged, and there ss the locking element and the receptacle are configured such that the standing platform parts of mutually adjacent grandstand seats in the open position of the locking element in the pivoting direction of the first joint are pivotable relative to each other and positively connected to each other in the closed position of the locking element in the pivoting direction of the joint.

With the help of the locking element and the matching receptacle having locking the Stehpodestteile of standing in a row adjacent tribune seats are interconnected or locked so that the front edges of Stehpodestteile this grandstand seats all arranged at the same height or in straight extension to each other are. By the locking device can in particular by manufacturing and / or mounting tolerances and / or caused by different weight of the grandstand seat user height differences between the floor pedestal parts and the seat parts of adjacent grandstand seats are compensated in a simple manner. If several in a row adjacent grandstand seats are used as a pedestal, thereby steps or paragraphs at which the users of the grandstand seats could stumble at the transition points between the grandstand seats avoided. When the interlocked grandstand seats serve as seats, the risk of clothing being clamped by the user in a gap located between the seat parts of mutually adjacent grandstand seats is reduced by the locking device. By means of the locking device, the standing platforms or the seat parts of mutually adjacent grandstand seats can also be supported against each other, whereby overall the stability of the grandstand seat or a seat row composed of several grandstand seats is improved.

As can be seen from the figures, a seat part 2 is attached to a standing platform part 1. The seat 2a of the seat part 2 is facing away from the standing platform part 1. The standing platform part 1 is connected at one side to the first socket of a first hinge 6 formed as a hinge. At the end facing away from the first joint 6, the standing platform part 1 is angled, which gives it greater stability.

Furthermore, a lug-shaped support element 7 is fastened to the standing platform part 1, to which a backrest 3 is fastened so as to be pivotable about an axis 3b via a lug 3a. The axis 3b is arranged such that the backrest 3 can be placed on the seat surface of the seat part 2 substantially without major displacements, as is especially the case FIG. 2 and 3 can be removed.

The second socket of the first joint 6 is fastened to a cross member 9 designed as a box profile, which is fastened to a post-shaped element 4 which is likewise designed as a box profile. At the end facing away from the cross member 9, the post-shaped element 4 is fixed to the first socket of a second hinge 5 designed as a hinge. The second socket of the second joint 5 is fixed to a bottom part 8, which in turn is mounted on a bottom 10.

In Fig. 5 it can be seen that on the cross member 9, a locking hook 6a is pivotally mounted, which is actuated by means of a rod 6b. In the locking position, the locking hook 6a engages behind an edge region of an opening provided in the standing platform part.

In the unfolded state of the tribune seat, the locking hook 6a extends through a correspondingly formed opening in the floor platform part 1 and engages behind this. This avoids that the standing platform part 1 can be pivoted about the pivot axis of the first joint 6.

At the first socket of the second joint 5 and on the post-shaped element 4, a locking rod 5a is attached. The locking rod 5a thus performs a pivoting movement of the second box-shaped profile 4 about the axis of the second joint 5 through a corresponding pivoting movement. In the unfolded state of the seat of the locking rod 5 a engages behind a movable locking element 5 b, which is arranged on the bottom part 8. As a result, the post-shaped element 4 is locked in its position.

To fold the tribune seat, the locking lug 6a and the movable locking element 5b are actuated, whereby the respective detents are canceled. As a result, the standing platform part 1 can be about the pivot axis of the first joint 6 and the post-shaped element 4 about the axis swing the second joint 5. The corresponding pivoting movements are represented by arrows 6 ', 5'. Furthermore, the backrest 3 is pivoted about the axis 3b on the seat surface 3a of the seat part 3.

In particular FIG. 4 can be removed, the standing platform part 1 is supported on the one hand by means of the support elements 7 on the floor 10 and on the other hand on the bottom part 8 from.

Furthermore, one can see by comparing the FIGS. 1 and 4 in that, in the folded state of the grandstand seat, the seat part 2 is located almost unchanged in the horizontal direction at the point where it is in the unfolded state of the grandstand seat. Only a slight displacement of the seat part in the backrest facing away from the horizontal direction is present. As a result, the seat can be used for example in bleachers with low step depth.

Like that FIGS. 6 and 7 can be removed, the post-shaped element 4 in the middle of the standing platform part 1 and the cross member 9 is arranged. As a result, only a post-shaped element is required.

As in Fig. 8 can be seen, the cross member 9 can be supported on the floor 10 via two spaced apart in the extension direction of the cross member 9 post-shaped elements 4. The post-shaped elements 4 are spaced from the lateral edges of the grandstand seat. Of course, the tribune seat according to the invention can also be realized in that the post-shaped elements 4 are arranged on the outer edges of the standing platform part 1 and the cross member 9.

It should also be mentioned that the tribune seat has a telescopic gas spring 13, which articulates at one end with a on the Cross member 9 arranged, spaced from the second joint 5 first abutment point and hinged at its other end with a arranged on the bottom part 8, also spaced from the second joint 5 second abutment point is pivotally connected. The gas pressure of the telescopic gas spring 13 exerts a pressure between the abutment points, which facilitates the raising or raising of the post-shaped element 4 for the user.

At the in Fig. 8 illustrated embodiment, three seat parts 2 are arranged in a row next to each other on the standing platform part 1. Each of these seat parts 2 is associated with a backrest 3, which is pivotally attached to two strap-shaped, arranged on the cross member 9 supporting elements 7.

Again Fig. 8 can be removed, is provided on a first side edge of the standing platform part 1 of the grandstand seat configured as an engagement opening 11 for a matching, detachably connectable to the receptacle 11 locking element 12 which is arranged on a laterally adjacent to the standing platform part 1 Stehpodestteil 1 another tribune seat , It can clearly be seen that the receptacle 11 is radially spaced from a pivot axis of the first lockable joint 6.

At the second side edge of the standing platform part 1 facing away from the first side edge, the grandstand seat has a locking element 12, which can be connected in a corresponding manner to a receptacle of a further adjacent grandstand seat.

The locking element 12 and the receptacle 11 are configured such that the standing platform parts 1 of the mutually adjacent grandstand seats in an open position of the locking device formed by the locking element 12 and the receptacle 11 in the pivoting direction of the first joint 6 relative are mutually pivotable. In a locking position of the locking device, the standing platform parts 1 of the mutually adjacent grandstand seats in the pivoting direction of the first articulation 6 are positively connected with each other.

In Fig. 10 It can be seen that the locking element 12 has a locking projection, which is arranged around a transverse to the main extension plane of the at least one standing platform part 1 locking axis, which is approximately at right angles to the plane of Fig. 10 runs, is pivotally connected to the standing platform part 1. In the open position, the locking projection is arranged completely below the standing platform part 1 and in the locking position the locking projection protrudes laterally against the standing platform part 1.
