Sales counter

The invention relates to a sales counter in accordance with 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, there is the area between the top of the evaporator and the goods tray Difficult to access and cannot be cleaned thoroughly, for example with a brush. These places 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, as 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 a pre-sale counter to show with a liftable evaporator, avoiding the aforementioned disadvantages of access to the evaporator chamber and to the evaporator and the handling of the evaporator are improved.

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 case of the prior art mentioned, in particular on the goods support 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 also be used 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 in terms of size and weight of the damper. 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 evaporator chamber, but they can also support each other, so that only one device directly and the other indirectly on the insulating floor bry. the side walls are supported.

lfl /

The lifting means can, for example, be hydraulic or pneumatic operated lifting rams or spindles exist that lift the evaporator from the insulating base. But the vaporizer can ' also cn one end with the insulating base or one of the aforementioned Side walls be articulated and at the other end one 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, which are each preferably connected to the evaporator and the insulating base in the manner of a four-link chain, allows the evaporator to be completely lifted off the insulating base using simple mechanical means. The links are arranged in the refrigerated counter in such a way that the swiveling movement of the evaporator is directed upwards and to the side of the refrigerated counter from which assembly and cleaning are carried out. The vaporizer moves towards the operator during its pivoting movement, who can thus more easily reach the rear of the vaporizer. When the evaporator is swiveled up, all parts of the evaporator chamber and the evaporator are accessible. In particular, ¹ can be passed between the evaporator and the insulating floor by hand and these areas can also be cleaned 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 run the evaporator t parallel to the insulating floor. For cleaning purposes, it is favorable Jj ₄ make the arm of each arm pair differing in length from · ', and the longer arm on the side of refrigerated display Toggle · ■ 5 assign, takes place from which the cleaning. With normal refrigerated counters, this is the buyer's side of the counter. In the swiveled-up position, the evaporator protrudes obliquely upwards, so that especially its underside and the part of the insulating floor lying underneath it ■; are very easily accessible.

So once the conception of refrigerated counters that is common today has been changed , and the refrigerated counters are cleaned from the operator's side, the handlebars would have to be arranged in such a way that the swivel. fj movement to this side takes place and any longer handlebars

are also arranged on this side. 15th

The further embodiment of the device according to the invention na-. claims 5, 6 and 7 enables improved handling of the evaporator. By replacing the rigid handlebars on the buyer's side with a finite length with variable-length handlebars, the evaporator can be set up even more steeply in a swiveled up position. The steeper an upright evaporator raqt upward, the easier it is to clean the underside of the evaporator thoroughly and with an _r from above downwardly directed water jet an operator. The variable length link must be locked in the \ 25 extended position, wherein the arrangement of a gas \ pressure spring or the like is particularly favorable _c as a variable length member but would also be a telescopic arm in question, which can be correspondingly positive or non-positively locked in the extended position .
\ 30.

The arrangement of gas springs also has the advantage of that these are stretched in the rest position and on the evaporator via the other links with their joints offset from one another exert a restoring moment that presses the evaporator against the Isclierboden. Also the joints with which the gas pressure springs are attached to the evaporator and insulating bottom, can be offset from one another, so that the gas spring is in the rest position is inclined downwards and its force is directed against the insulating floor.

-] 0 Advantageously, the handlebars limit their own swivel travel by a stop and crretieren with it in the upright position Location. This stop can be present on one or both links of a link pair. The pivot travel of this handlebar is dimensioned so that they swivel a little beyond the vertical position and then come to a stop. In this position the weight of the evaporator presses this link against its stop so that the evaporator does not unintentionally return to the rest position can swing back.

The device features of 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 slid or folded away. On the other hand, the evaporator can be pushed against this pivoting system will. The shifting movement, which is independent of the pivoting movement, has the advantage that the evaporator is still further to Can be moved to the buyer side and its back is thus even more accessible. This measure is above all also useful for working on the evaporator on Mondays in idle position. the The best accessibility to the rear of the evaporator results when that Swivel system with the evaporator is swiveled around the joint on the insulating floor. This is especially important when the installations

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

With the devices according to the invention it is possible to use the evaporator to move to different positions so that all sides 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 prior art, it can also Any size and weight evaporator can be moved.

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

Figure 1: A cross section through a refrigerated counter in the open state,

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

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

In the exemplary embodiment in FIG. 1, a refrigerated counter 14 is shown in cross section with 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 handlebars, each evaporator being equipped with at least two such pairs of handlebars over its length is. Depending on the size and weight of the evaporator, there can 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's 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, thereby relieving 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 V / cr 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 is an enlarged cross-section through an evaporator, In the preferred Embodiment are the handlebars 3.7 of each handlebar

15pairs arranged in line one behind the other and pivot in the same direction. The embodiment shown is only one of many possible Types of steering gear and can be modified to this effect, for example be that the two links are 3.7 equal in 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

25lenk 5 connected to the evaporator 1. The joint 4 is thereby of a U-shaped rail 10, which is connected to the insulating base 2 and of which only the web can be seen in Figure 2, the evaporator

term joint is likewise mounted U-shaped in a rail 11 which is in turn ^ _berbunden with the evaporator. 1 The nature of the overall gle.lche t / 301enklagerung is found at the handlebar 7, the joint 8 isolierbodenseitiges over said SchienelO with the insulating bottom 2 and its vaporized erseitiges joint 9 via the other rail 11 to the evaporator

connected is. In the rest position of the evaporator, the gas spring 3 and the link 7 are parallel to the insulating base 2. The joints 3 and 9 of the shorter link 7 are offset from one another so that the evaporator-side joint 9 has a greater distance from the Isolier'ooden than the insulating bottom-side joint 3 _e 3 exerts, due to the distance between the joint 9 and the joint 8, a restoring moment on the handlebar 7, as a result of which the evaporator 1 is held on the insulating box 2. The insulating base-side joint 8 is from the mid-length plane of the handlebar 7 to it Offset towards the edge, whereby when the link 7 is pivoted about the joint S, the end face 7 α hits the insulating base 2 or the rail 10 and, as a stop dcmit, limits the pivoting travel of the link 7. This stop position of the link 7 is shown in FIG On its pivoting path, the link 7 should pivot a little beyond the vertical position, which is achieved by a bevel of the end face 7 α e other end face adjacent to the joint 9 can also be beveled. The technical features of the handlebar space described in FIG. 2 naturally apply to all handlebar pairs of an evaporator. In F; ~ ur arrangement of an evaporator 1 with folded-in rest position under sen Eoden links 3.7 shown can be modified so dal the links are arranged adjacent to the evaporator or in recesses on the bottom of Verdcnpfers, whereby the evaporator directly on the Isolierbodan 2 would sit on and further construction height could be saved.

Figure 3 shows a side view of the evaporator from the direction of arrow A in Figure 2. The schematically in the form of a box shown evaporator 1 has an evaporator bottom 1 α, the one with the U-shaped rail 11, the opening of which faces downwards 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, which means that both rails are in the rest position of the evaporator interlock like a box. The rails 10 and 11 thus form one on the end faces 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 that interlock the box-like the rails 10 and 11 allows.

In a preferred embodiment, the evaporator 1 is on its rails 11 displaceable and lockable in the longitudinal direction thereof arranged. This displacement device is not shown in the drawings and can be generally understood in the art known machine parts, such as a dovetail guide, which can be clamped by means of a screw is. Such a movable connection can also exist between the insulating base 2 and its rails 10.

In Figure 4, an open refrigerated counter 14 is shown in cross section.
30th

In this exemplary embodiment, the rail 10 on the insulating floor side is connected in an articulated manner to the insulating floor 2 via a pivot bearing 17 which is arranged on the buyer side 15 of the refrigerated counter 14. With . undressed ... - Lines is the upright position of 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 FIG. 4, the pivoting movement of the rail 10 and the erected evaporator 1 is limited by the contact of the evaporator against the side wall 18. In this position, especially the rear side of the evaporator 1, which is adjacent to the shorter link 7, is very easily accessible. The rail 10 can also be folded up without the handlebars 3, 7 pivoting the evaporator 1 from the rail 1. * 10. In addition, as in the other exemplary embodiments, the evaporator 1 can be movably guided on the rails Π. The rest position of the evaporator 1, in which it rests on the insulating base 2 with rails 10, 11 folded over one another, is shown in dashed lines.
20th

A variation of the exemplary embodiments described in the figures consists in the fact that the links of each link pair can be rigid and of the same length. Likewise need for storage the handlebars no rails 10, 11 are present, it is sufficient for it simple cloths with which the handlebars can be swiveled on the evaporator and on the insulating base. Has such a lifting means then only the one degree of freedom of the pivoting movement of the handlebar

instinct.

Handles are attached to the evaporator with which an operating person can move the vaporizer.
