Description

The invention relates to a device for pivoting a disc, in particular a glass pane, at a sales counter, according to the type mentioned in the preamble of claim 1. The term disc is understood here to mean any shape of disc, such as a vertically arranged disc in normal operation, but also horizontally or obliquely arranged panes, curved or straight panes or even panes joined at angles. Individual so-called number plates can also act as discs in the sense of the invention.

In sales counters, it is always desirable if the disc, which is usually arranged in normal operation between the customer and the goods, can be pivoted to re-stock, for example, the sales counter, but also to the sales counter or the disc from the inside too clean. It may also be desirable to pivot the disc to turn a service counter into a self-service counter.

In most cases, the pivoting movement of the disc is supported by a gas pressure spring to make the pivoting movement easier and more ergonomic for the operator. Here, a joint is usually provided, which Also includes a glass holder for the disc and by means of which the disc is pivotable. If the disc is to be pivoted about a horizontal Schwenkache, so this is possible with conventional devices until the dead center is reached, in which the center of gravity of the disc is arranged directly perpendicular to the pivot axis. Now, however, the disc is further pivoted, for example, to make the inside of the disc for cleaning more accessible, it may happen that the disc by gravity and additionally with the support of the gas spring experiences an additional drive, resulting in accidents or property damage in the area of the disc, the profile or the joint can lead. It may also happen that the disk moves by its own momentum beyond its dead center, but this would lead to the same results. In addition, an operator wishing to return the disc to its original condition would have to work against the force of the gas spring to facilitate this.

The EP2471418A1 shows a refrigerated display, the glass pane is partially pivotally mounted about a horizontal axis to convert the refrigerated counter from a service counter in a self-service counter. A gas spring is not provided here, so the operator must hold the pivoting disc by hand when it has exceeded its center of gravity. However, especially with large counters, the disc is very heavy which can quickly lead to accidents.

The DE29914069U1 describes a sales counter with a pivotally mounted about a horizontal axis disc. The pivoting movement of the disc is supported by a gas spring. Here, however, it is only possible to bring the disc up to a relatively vertical position. This is impractical for an operator if he wants to clean the inside of the disc, as this is not optimally reached by the limited opening of the glass. In addition, the upwardly pivoted disc is disturbing when work, such as cleaning, assembly, etc. are to be carried out in the area of the goods display.

In the DE 3235371A1 is a counter top with lifting handle described. Again, a gas spring to support the lifting movement is provided, but again, the disc can not be pivoted beyond its center of gravity, which again brings the aforementioned problems.

The object of the invention is therefore to develop a device for pivoting a disc, which avoids the aforementioned disadvantages and allows pivoting of the disc safely beyond the dead center. This object is solved by the characterizing features of claim 1, which have the following special significance.

Both ends of the gas spring are movably mounted, such that the further pivoting of the disc, in particular beyond the dead center, the force-supporting effect of the gas spring is turned off, so this remains virtually without effect. Then an operator can safely move the disc beyond its dead center and the risk of accidents can be reduced. Under movable in the sense of this invention, any movement is to be understood in which the relevant end of the gas spring moves in space, for example by a pivoting movement or a translational movement. A purely rotational movement about a point or an axis, in which the point or the axis and thus also the end of the gas spring does not move in space, does not fall under the term "movable".

In conventional devices for pivoting a disc, one end of the gas spring is fixed to the profile only rotatable by one point. This results in the known and already mentioned disadvantages of the prior art. Due to the movable mounting of both ends of the gas spring, the force-supporting effect of the gas spring can be switched off if necessary, so that no force support of the gas spring takes place in an undesirable direction.

It is particularly advantageous if the movement of the disk, in particular also beyond the dead center or also in another area, for example a few degrees before the dead center, is damped. Thus, the accelerating effect of gravity on the disc is reduced and the disc is ergonomic for an operator and even safer to pivot.

It is furthermore advantageous if a buffer, in particular of an elastic material, is provided on which the disc comes to rest in its open position. This buffer prevents, even with an undamped pivoting movement of the disc damage to property. In addition, noise generated by the stopper is damped.

In a first particularly preferred embodiment, the first end of the gas spring is arranged on a sliding member which is slidably mounted in or on the profile, wherein a damper is provided, which dampens the sliding movement of the sliding member. The gas spring acts as a coupling rod, in which no piston movement takes place. As a result, the movement of the joint and thus the disc is directly damped. It is possible to provide the gas spring with an additional means, such as a sleeve, which prevents tensile forces from being transmitted to the gas spring.

As a damper, for example, a linear damper can be used here. The movement of the disc is then, for example, to the dead center, as in the prior art. Thereafter, however, moves the first end of the gas spring on the sliding member in profile against the action of the damper, whereby no piston movement of the gas spring takes place and so the pivotal movement of the disc is damped. In this embodiment, therefore, the first end of the gas spring is movably mounted on the sliding element, while the second end of the gas spring is mounted on the joint such that it is pivotable with the joint.

In the aforementioned embodiment, it is advantageous if the movement of the sliding element is limited by one or two stops. The slider and the damper are arranged between them using two stops. This results in an exact and precisely adjusted movement possibility for the first end of the gas spring. The disc facing away from the stop can also serve directly as an adjustment for the disc in the untwisted state. Depending on the exact arrangement and orientation of this stop then the disc can be adjusted accordingly.

Further preferred in this embodiment, caps made of elastic material are provided on the sliding element and / or on the one or more stops. These serve the impact and sound damping, so that when moving the slider to the attacks no disturbing noise, such as rattling, may arise.

Particularly simple is the embodiment described so far can be realized when the sliding element is arranged in a recess of the profile, wherein at the height of the sliding element in profile a slot is provided. The first end of the gas spring can then be connected through this slot with the slider. The slot allows the movement of the sliding element in the profile, even if the gas spring is connected to the sliding element.

In particular, in this embodiment, it is of course also possible that on two adjacent discs, which are arranged on a common profile, two gas springs, two sliding elements and two dampers are provided. The dampers are then, for example, next to or above each other. The sliding elements are preferably in the same Recess of the profile arranged and can slide freely and independently in this, as well as past each other.

A second preferred embodiment provides that a second gas spring is provided in addition to the first gas spring. The pivotal movement of the disc is in at least two sections in front of it, wherein the first portion of the pivoting movement is supported by the first gas spring, while the second portion of the pivoting movement is supported by the second gas spring. There may also exist portions of the pivoting movement, which are quasi a hybrid form, in which support both the first and the second gas spring, the pivoting movement. In this embodiment, the disc is pivotable at an even greater angle. Preferably, the first gas spring is mounted with its first end on the hinge and with its second end to a pivot member, while the second gas spring is arranged with its first end to a control arm and with its second end to the profile. The first gas spring is thus movably mounted again with its two ends, since both the pivot member and the joint can be moved and move the corresponding ends of the gas spring with. The second gas spring is movably mounted only at its first end, with which it is arranged on the control arm. The second end of the second gas spring is immovable, but arranged rotatable about a point on the profile.

Preferably, in the last-described embodiment, the pivot member is designed as a deflection lever, which is arranged in the rest position of the disc in a recess in the profile.

Further advantageously, a Wegbegrenzer is provided on the control arm, which limits the first portion of the pivoting movement and thus the piston movement of the first gas spring and brings about the second portion of the pivoting movement. After completion of the first portion of the pivoting movement then finds no piston movement in the first Gas spring more instead. Since the gas spring is preferably not fully extended, the gas spring takes on no tensile forces, which is advantageous and increases the life of the gas spring.

Further advantageous in this embodiment is when the control arm or the Wegbegrenzer serves as a driver for the second gas spring and is moved in the second portion of the pivotal movement of the disc of this or the joint. As a result, the first end of the second gas spring is automatically moved with and the second gas spring so pivoted. It is also possible to form control arm and pivot member in one piece.

Finally, a lock can be provided between the two sections of the pivoting movement, which prevents the second portion of the pivoting movement takes place when the lock is not moved to an unlocking position.

In a further preferred embodiment, the first end of the gas spring is attached to a pivotally mounted lever. The second end of the gas spring is mounted on the joint. Both ends of the gas spring are each also rotatably mounted about an axis. During the pivotal movement of the disc initially only the gas pressure spring lingers while the lever remains in its original position. Thus, the gas spring supports the beginning of the pivoting of the disc. After the disc has reached something in the area of its dead center, the length of the gas spring is no longer changing. If the disc is now pivoted further, so now pivots with the lever, wherein the first end of the gas spring rotates only about the pivot point on the lever and so the gas spring has no effect on the pivoting operation of the disc. From the time that the disc is still in its non-pivoted home position to the time the gas spring has reached its maximum length, the first end of the gas spring and the lever may abut against an abutment area to gain space save and create a more appealing overall appearance of the closed disc at the sales counter. Here, the first end of the gas spring indirectly - for example, with the interposition of a portion of the lever - or rest directly on the investment area.

Fig. 1 shows a device 10 according to the invention with a gas spring 20, which is arranged with its first end 21 to a slot 27 of the profile 13 and with its second end 22 to the joint 14. In Fig. 1 is the disc 12, which is not shown here in detail in its initial state.

The FIGS. 2 and 3 now represent the movement of the disc 12 when performing its pivotal movement. In Fig. 2 the disc 12 is already pivoted by about 90 ° about its pivot point 15. The center of gravity 16 is located in Fig. 2 However, even before the fulcrum 15 so that the pivotal movement of the disc 12 is supported in this area by the gas spring 20. However, it is different in a continuation of the pivoting movement of the disc 12 to the in Fig. 3 illustrated situation. It can be seen that now the center of gravity 16 is arranged behind the axis of rotation 15. In the area between dead center and the in Fig. 3 In a situation according to the state of the art in which the first end 21 of the gas spring 20 is fixedly attached to the profile 13, the disc 12 could fall behind in this last turning range due to its gravity, which can lead to accidents and property damage , Out Fig. 3 However, it can be seen that the first end 21 of the gas spring 20 in the slot 27 in comparison to the illustration in Fig. 2 has moved. As a result, the pivoting movement of the disc 12 is also up to the in Fig. 3 muted position shown. This is due to the internal structure in the 4 to 6 is explained in more detail.

Fig. 4 shows here a similar representation, as Fig. 1 However, here is the not shown disc 12 in the in Fig. 2 shown position. The first end 21 of the gas spring 20 is attached to the slider 23, not shown here in the interior of the profile 13 and arranged on the right end of the slot 27 in the illustration. The sliding member 23 rests against the stop 25, as Fig. 5 shows. On the other side of the sliding member 23, a damper 24, here a linear damper, is arranged. Will now be the disc of the in Fig. 2 shown position in the Fig. 3 brought shown position, the sliding member 23 moves in the recess 17 in the profile 13 in the Fig. 4 and 5 to the left, so that the sliding member 23 cooperates with the damper 24. Here, the first end 21 of the gas spring 20 then also moves to the left until it comes to rest on the left end of the slot 27, as from Fig. 3 seen.

The exact components of this arrangement will be out again Fig. 6 closer, which shows a partial exploded view. It can be seen that two stops 25 are provided. These have on their the damper 24 and the sliding member 23 facing the end caps 26 made of elastic material. These serve to dampen the sound when the sliding element 23 moves in the recess 17 in the profile 13. The sliding element 23 may preferably consist of a plastic which is as abrasion-resistant and wear-resistant as possible, but has a smooth surface.

The Fig. 7 to 12 show a further embodiment of the device 10 according to the invention. In addition to the first gas spring 20, whose two ends 21, 22 are arranged to be movable, a second gas spring 30 is still provided. This is also arranged movable with its first end 31, while the second end 32 rotatably fixed by a point on the profile 13 and thus is not movable in space. Fig. 7 shows now the initial situation in which the disc 12 is arranged on the sales counter 11. Such arrangements are common at service counters. The first gas pressure spring 20 is arranged with its first end 21 on the hinge 14, while the second end 22 is fixed to a pivot member 33. As a pivot member 33, a lever is provided here. The second gas spring 30 is fixed with its movable first end 31 on a control arm 35, while the second end 32 of the second gas spring 30 is immovably but pivotally mounted on the profile.

The movement of the in Fig. 7 shown arrangement is in the Fig. 9 to 12 shown. In the FIGS. 9 and 10 This is the first portion of the pivotal movement of the disc 12. The first gas spring 20 is elongated, there is a piston movement in the first gas spring 20, the second gas spring 30 is in this movement uninvolved. At the in Fig. 10 shown position then proposes the joint 14 against the Wegbegrenzer 34. From here there is no piston movement of the first gas spring 20 more, that is, the first end 21 and the second end 22 of the first gas spring 20 remain at the same distance from each other.

If the disk 12 is now pivoted further, the second section of the pivoting movement begins. In this pivotal movement of the disc 12 in the second section, the joint 14 and the Wegbegrenzer 34 remain in contact with each other. As a result, the control arm 35 is moved and thus also the first end 31 of the second gas spring 30th Fig. 12 now shows the end of the second portion of the pivotal movement of the disc 12th

Of course, it is also conceivable to provide another sequence of movements, in which at the end of the second portion of the pivoting movement, the disk 12 has been further pivoted away from the sales counter 11 away. In the Fig. 12 shown situation has the advantage that when cleaning the inside of the disc 12 no cleaning liquid can run in the display surface of the counter and so could pollute, for example, issued there goods.

In the Fig. 13 to 16 a third embodiment of the device 10 according to the invention is shown. The gas spring 20 is articulated with its first end 21 to a lever 40. With its second end 22, the gas spring 20 is articulated to the joint 14. As in particular from the FIGS. 14 and 15 it can be seen, elongated at a pivoting movement to the opening of the disc 12 first, the gas spring 20 to support this pivoting movement. However, as soon as the disc 12 has reached approximately its dead center, the length of the gas spring no longer changes and it begins to pivot the lever 40, on which the first end 21 of the gas spring 20 is articulated, to pivot. This pivotal movement of the disc 12 can then be carried on until the maximum opening of the disc 12, as in the Fig. 15 and 16 shown is reached. The hinge 14 is applied to the buffer 18, so that no hard impact at the end of the movement of the disc 12 takes place. Such a buffer 18 could also be designed differently and, for example, interact directly with the disk 12.

Finally, it should be pointed out that the embodiments shown here are merely exemplary realizations of the invention. This is not limited to this. On the contrary, modifications and modifications are possible. It can be seen that in all embodiments, both ends of the gas spring move in space, often by movements with rotational and translational share. A pure rotational movement about an axis passing through an end of the gas spring axis is thus not meant. By this movement of the gas spring whose effect can be virtually eliminated to avoid the aforementioned disadvantages. Therefore, other embodiments of the inventive concept, which describe exactly such movements of the gas spring, expressly covered by the invention. The term "dead center" is also to be interpreted broadly in the context of this invention. This does not mean that the support of the gas spring acts exactly until it reaches the dead center and is switched off directly there. Rather, the supporting effect of the gas spring can also be switched off a little before or a little after reaching the physical dead center. At what point this happens exactly depends on the particular application.
