Sales counter

The invention relates to a sales counter according to the features of the preamble of the main claim.

From DE-GM 79 07 471 it is known for a sales counter to attach the evaporator to the underside of a goods tray and swivel both up together for the purpose of cleaning. This arrangement has the disadvantage that the attached evaporator is very difficult to clean. On the one hand, the area between the top of the evaporator and the goods is tragbo.den Difficult to access and cannot be cleaned thoroughly, for example with a brush. These spots can only be superficial be sprayed with a shower, the operator the back-splashing water of the necessarily from below is exposed to an upward jet of water. It is also disadvantageous that the pivot joint of the goods support floor is adjacent The rear of the evaporator is difficult to access for assembly and cleaning work. The connection between the shelf and the evaporator It also requires a lot of construction work, since the goods support floor and the lifting mechanism are accordingly due to the weight of the evaporator need to be reinforced. In the practical implementation of this previously known teaching, one has therefore switched to the evaporator to make it as small as possible. So that the required cooling capacity can be achieved, it is necessary with essential to work lower temperatures of the coolant, which in turn leads to the disadvantage that the cooling air dries out to a greater extent.

The invention is therefore based on the object of providing a sales counter with a liftable evaporator, in which the access to the evaporator chamber and to the evaporator as well as the handling of the evaporator are improved while avoiding the aforementioned disadvantages.

The invention solves this problem by a device according to the characterizing part of the main claim. The separation of the evaporator and the goods support base has the advantage that the surface of the evaporator and the goods support base individually without any problems and can be cleaned thoroughly. The areas that are difficult to access in the prior art mentioned, in particular on the goods carrying floor facing evaporator side are avoided in the subject matter of the invention because the goods support base is pivoted away from the evaporator can be.

The refrigerated counter according to the invention can be with a single or be equipped with a number of several evaporators. The use of its own lifting means for each individual evaporator is free Choice with regard to the dimensioning of the size and weight of the dampers. The lockability of the erected lifting means leaves the evaporator in a stable position in each of its planned positions ingestion that he cannot accidentally leave. The lifting means are advantageously supported for reasons of stability on the insulating floor. The lifting means can, however, also be hinged to the side walls of the evaporator chamber. Depending on, the movements of the evaporator can be made by the lifting means from several devices, for example pivoting or sliding devices and the like. These devices can each be directly on the insulating base or the side walls of the Support the evaporator chamber, but they can also oppose each other support so that only one device is supported directly and the others indirectly on the insulating base or the side walls.

The lifting means can consist, for example, of hydraulically or pneumatically operated lifting rams or spindles, which the Lift the evaporator off the insulating floor. However, the evaporator can also be connected to the insulating base or one of the aforementioned at one end Side walls be articulated and at the other end also connected to the insulating floor or the side walls Have a lifting mechanism with which it can be folded up around this joint.

A particularly advantageous embodiment of the invention is the Device according to claims 2, 3 and 4. The arrangement of at least two pairs of links for the individual evaporator, each of which is preferably connected to the evaporator and the insulating base in the manner of a four-link chain, allows the evaporator completely with simple mechanical means lift off the insulating floor. The handlebars are arranged in the refrigerated counter in such a way that the swiveling movement of the evaporator follows is executed above and to the side of the refrigerated counter, from which the assembly and cleaning takes place. The vaporizer comes in counter to its pivoting movement of the operator, who can thus more easily reach the rear of the evaporator. When the evaporator is swiveled up, all parts of the evaporator chamber and the evaporator are accessible. In particular, can hand through between the evaporator and the insulating base and also clean these areas thoroughly with a brush.

In the rest position, the evaporator sits flat on the insulating floor and is therefore not or only slightly higher than a permanently installed evaporator.

If all handlebars are of the same length, they always drive the evaporator parallel to the insulating floor. For cleaning purposes it is favorable to make the handlebars of each pair of handlebars different lengths, and the longer handlebars on the side of the refrigerated counter from which the cleaning is carried out. With usual cooling counter this is the buyer's side of the counter. In the swiveled up position, the evaporator protrudes diagonally upwards, which makes it special its underside and the underlying part of the insulating floor are very easily accessible.

Should the conception of refrigerated counters that is common today be changed and the refrigerated counter are cleaned from the operator's side, the handlebars would have to be arranged so that the pivoting movement takes place towards this side and any longer handlebars are also arranged on this side.

The further embodiment of the device according to the invention according to claims 5, 6 and 7 enables improved handling of the evaporator. By replacing the rigid link on the buyer's side with a finite length with variable-length links the evaporator in the swiveled up position. set up even more steeply will. The steeper an upright vaporizer protrudes, the easier it is for an operator to see the underside of the vaporizer thoroughly and with one directed from top to bottom Clean water jet. The variable-length handlebar must be in the be locked in the extended position, the arrangement of a gas pressure spring or similar is particularly favorable. As variable in length Link could also be a telescopic arm that locks in the extended position with a corresponding positive or non-positive fit can be.

The arrangement of gas pressure springs has the further advantage that they are tensioned in the rest position and on the evaporator Exercise a restoring moment on the other links with their joints offset to one another, which the evaporator against the Insulating floor presses. The joints with which the gas pressure springs are attached to the evaporator and insulating base can also be offset from one another, so that the gas pressure spring is in the rest position is inclined downwards and its force is directed against the insulating floor.

Advantageously, the handlebars limit their own swivel travel by a stop and thus lock yourself in the upright position. This stop can be on one or both links of a pair of handlebars. The pivoting path of this link is dimensioned so that a piece over the vertical position swing out and then come to the stop. In this position, the weight of the evaporator presses these links against theirs Stop so that the evaporator cannot unintentionally swivel back into the rest position.

20 .. The device features from claims 8, 9 and 10 give the Evaporator further kinematic degrees of freedom. The handlebar pairs with their rails form a swivel system that is opposite to the The insulating floor can be moved or folded away. On the other hand, the evaporator can ver be pushed. The from. the swivel movement independent displacement movement has the advantage that the evaporator can be moved even further to the buyer's side and so its back is even more accessible. This measure is particularly useful for assembly work on the evaporator in the rest position. the The best accessibility of the rear of the evaporator results when the swivel system with the evaporator is swiveled around the joint on the insulating base. This is especially important when the installations

for the coolant supply line on the rear of the evaporator are arranged.

With the devices according to the invention it is possible to move the damper in different positions so that all

Pages can be cleaned comfortably and thoroughly one after the other and the assembly of the evaporator in the refrigerated counter is greatly simplified. In contrast to the state of the art, this also allows Any size and weight evaporator can be moved. 10

Details of the invention emerge from the drawings. In the invention is shown schematically and by way of example to them. Show it:

FIG. 2: an enlarged cross-sectional view of an evaporator, FIG. 3: an enlarged side view of the evaporator according to arrow A. from Figure 2 and

FIG. 4: a cross section through an open refrigerated counter with the evaporator swiveled up and down.

In the exemplary embodiment of FIG. 1, a refrigerated counter 14 is shown in cross section with the front glass pane 13 folded up on the buyer side and with raised goods tray 12 and attached fans 16 shown. An evaporator 1 protrudes obliquely towards the buyer side 15 above and is articulated to an insulating base 2 via links 3 and 7. The links 3, 7 are in the same cross-sectional plane the refrigerated counter 14 and form a pair of links, each evaporator is equipped over its length with at least two such pairs of links. Depending on the size and weight of the vaporizer, it can also be three or more pairs of handlebars. Each pair of handlebars 3.7

forms a link mechanism with the evaporator 1 and the insulating base 2 in the form of a four-link chain that is forced to run. In the exemplary embodiment In FIG. 1, the links 3, 7 of each pair of links are of different lengths, with the longer link on the buyer side 15 is arranged and is designed as a gas pressure spring. This gas pressure spring gives the steering gear a further degree of freedom by relaxing when the handlebars are swiveled and thereby the Evaporator 1 rotates upwards around its joint with handlebar 7. The evaporator 1 is in its rest position on the insulating base 2 and

10 the goods support base 12 in the folded-down state is shown with thin dashed lines.

In comparison with the very simplified representation of the figure, FIG. 2 shows 1 shows an enlarged cross section through an evaporator. In the preferred embodiment, the handlebars 3.7 of each handlebar

15 pairs arranged in alignment one behind the other and pivot in the same direction. The embodiment shown is only one of many possible Structures of link gears and can be modified, for example, so that the two links 3, 7 are of the same length, in opposite directions swivel, coupled to one another only on one side of the evaporator

20 are arranged or the like. The link mechanism can also have a different number of handlebars.

Figure 2 shows the rest position of the evaporator 1 with folded Links 3.7 represent on the insulating base 2. The gas pressure spring or the link 3 is connected to the insulating base 2 via a joint 4 and via a joint

connected is. The gas springs 3 are in the rest position of the evaporator and the link 7 parallel to the insulating floor 2. With .6 is the line of force denotes the gas pressure spring 3, which has no component perpendicular to the insulating base 2. The joints 8 and 9 of the shorter link 7 are offset from each other, so that the evaporator-side joint 9 a has a greater distance from the insulating base than the joint 8 on the insulating base side 2 parallel force of the gas pressure spring 3 exerts a restoring moment because of the distance between the joint 9 and the joint 8 the handlebar 7, whereby the evaporator 1 is held on the insulating base 2 will. The joint 8 on the insulating base side is offset from the central longitudinal plane of the link 7 towards its edge, as a result of which when pivoting of the link 7 around the joint 8, the end face 7 α hits against the insulating base 2 or the rail 10 and thus the pivoting path as a stop of the handlebar 7 limited. This stop position of the link 7 is shown in dashed lines in FIG. On its swivel path the Pivot handlebar 7 a little beyond the vertical position, which is achieved by chamfering the end face 7 α. The joint 9 adjacent other end face can also be beveled. The technical features of the pair of links described in FIG naturally apply to all pairs of handlebars in an atomizer. The arrangement shown in the figure of an evaporator 1 with in the rest position below it Bottom-folded handlebars 3.7 can be modified so that the handlebars next to the evaporator or in recesses on the underside of the evaporator are arranged, whereby the evaporator would sit directly on the insulating base 2 and further construction height can be saved could.

FIG. 3 shows a side view of the evaporator from the direction of arrow A in Figure 2. The evaporator 1 shown schematically in the form of a box has an evaporator bottom 1 α, the one with the U-shaped rail 11, the opening of which is downward to the insulating floor 2 indicates, is connected. The insulating base 2 is connected to the also U-shaped rail 10, whose Opening pointing upwards to the evaporator. The rail 11 is wider than the rail 10, as a result of which both rails interlock like a box when the evaporator is in the rest position. the Rails 10 and 11 thus form one on the front sides Cover caps completely closed box, which accommodates the handlebars 3 and 7 and protects against external influences. the end FIG. 3 also shows that the bolt of the joint 4 for the gas pressure spring 3 is mounted in the legs of the rail 10.

The rail 10 does not have for the bolts of the joints 5 and 9

shown recesses, which enables the box-like interlocking of the rails 10 and 11.

In a preferred embodiment, the evaporator 1 is on his rails Π arranged displaceably and lockable in their longitudinal direction. This shifting device is in the Drawings not shown and may consist of machine parts well known in the art, such as a dovetail guide that can be clamped by means of a screw. Such a movable connection can also exist between the insulating base 2 and its rails 10.

An open refrigerated counter 14 is shown in cross section in FIG.

W (m V IV IW

In this exemplary embodiment, the rail is on the insulating bottom side 10 is connected in an articulated manner to the insulating base 2 via a pivot bearing 17, which is arranged on the buyer's side 15 of the refrigerated counter 14. With solid lines is the straightened position the swivel system 3,7,10,11, and the evaporator 1 shown. The rail 10 is folded up around the pivot bearing 17 from the insulating base 2 and the evaporator is pivoted away from the rail 10 by the links 3, 7, which in turn are mounted in rails 11. As shown in Figure 4, the pivoting movement of the rail 10 and the erected evaporator 1 are limited by the abutment of the evaporator on the side wall 18. In this position is before especially the rear of the evaporator 1, which is adjacent to the shorter link 7, is very easily accessible. The rail 10 can also be folded up be without the handlebars 3.7 the evaporator 1 from the rail Pivot 10. In addition, as in the other exemplary embodiments, the evaporator 1 can be movably guided on the rails 11 be. The position of rest of the evaporator 1, in which it is seated on the insulating base 2 with rails 10, 11 folded over one another, is shown in dashed lines.

A variation of the exemplary embodiments described in the figures is that the links of each link pair are rigid and can be of the same length. Likewise, no rails 10, 11 have to be present for the storage of the handlebars, they are sufficient for this simple cloths with which the handlebars can be swiveled to the evaporator and to the insulating base. Has such a lifting means then only the one degree of freedom of the pivoting movement of the link mechanism. Handles are attached to the evaporator with which an operating person can move the vaporizer.
