Description

Application area

The proposed utility model relates to sliding shelves for a refrigerated display case.

Prior art

Refrigerated display cases are widely used, see patents Nos. SU1171653, US6189707, US6021908, which use sliding shelves, see patents Nos. US3242885, US4620489, US5970887, US6375015, US5720230, US5735589, US5403084, US5340209.

The use of sliding shelves allows you to solve the issue associated with the rapid movement of food products located on the display surface of the shelf closer to the buyer (in his field of view) to ensure a better demonstration of the products. The use of sliding shelves also simplifies the process of loading and unloading shelves with products, as well as simplifies their accounting.

Also, the use of sliding demonstration shelves allows you to avoid "stale" products and thereby reduces the costs associated with the cancellation of expired products located on the shelves.

Known retractable shelves for refrigerated display cabinets have a design complexity caused by the difficulty of separating the shelves from the brackets in order to quickly replace it using various kinds of tools.

Also, the production of a sliding shelf requires a large number of technological operations using additional special equipment, which complicates and increases the cost of their production. Also in the well-known retractable shelves, a complex principle (mechanism) of extension with the content of complex parts and mechanisms for the manufacture of which requires special technological equipment (for example, dies, molds, etc.), which are difficult to transfer to the manufacture of other sizes, is used. All this complicates the production process of sliding shelves for different sizes of display cases, that is, the dimensions of display cases can depend on the architectural features of the room in which the refrigerated display case is located, or on the decision of the designer / designer.

Since the drawer is used at low temperatures, which constantly fluctuate, this leads to the formation of condensate and a thermal change in the steels of which the guides are made. This may complicate the movement of the demonstration surface of the shelf, loaded with products.

The essence of the utility model

The objective of the proposed utility model is to develop a simple design of the sliding shelf, the use of which provides a quick replacement of the demonstration surface of the shelf located in the refrigerated display case without the use of various kinds of tools.

Another objective of the proposed utility model is the development of a retractable shelf easy to manufacture and repair, as well as operation.

Another objective of the proposed utility model is to expand the arsenal of constructive solutions for demonstration shelves for refrigerated display cases.

Other objectives and advantages of the proposed utility model will be discussed below as the presentation of the present description and figures.

A known shelf of a refrigerated display case comprising a retractable display surface, on the sides of which are sliding rails that move along the guide rails of the brackets, which comprise means for fixing the brackets in said refrigerated display case, according to the proposed utility model,

said guide rail of the brackets is made in the form of a guide bend of the upper part of the brackets facing the middle of the said surface, and along the upper surface of the guide bend a sliding pad is fixed to move the sliding guide, on the sides of which an external and internal bends are formed that prevent the horizontal sliding of the sliding guide from the slip pad and on the back side of the surface at the end of the sliding guide the surface tipping limiter ta is fixed to, that it is located under the lower surface of the guide limb.

Using the proposed utility model allows you to quickly disconnect the demonstration surface from the brackets in a drawer mounted in a refrigerated display case without using a special tool. The execution on the sides of the sliding guide of two bends, external and internal, which are located along the side surfaces of the slip lining, simplifies the process of manufacturing surfaces, and also increases the rigidity of the structure and simplifies the installation process of removing the demonstration surface from the brackets. Moreover, when using the proposed utility model, there is an increase in the contact area of the guide brackets and the demonstration surface, which makes it possible to evenly transfer the load caused by the weight of the goods on the demonstration surface. Also, due to the presence of internal and external bends of the sliding guide, it is possible to use large tolerances of landing, and this eliminates the need to produce slip plates with great accuracy.

Also, according to the embodiment of the proposed utility model, on the lower surface of the guide bend of the brackets there is a restrictive stop of the surface extension, which interacts with the front surface of the tipping limiter. The use of the limit stop allows you to adjust the amount of extension of the demonstration surface and thereby allows you to set the optimal lever and contact area of the guide rails of the bracket and the demonstration surface, preventing deformation or damage to the slip lining and the support rail, and this leads to an increase in the shelf life.

Also, according to an embodiment of the proposed utility model, side stops are located on the sides of the front end side of the demonstration surface. The use of side stops reduces the impact of the demonstration surface on adjacent shelves or side surfaces of the refrigerated display case.

Also, according to an embodiment of the proposed utility model, a rear stop is arranged along the rear (rear) side of the demonstration surface between the support rails, made in the form of a U-shaped profile facing away from the demonstration surface. The use of the rear limiter prevents the loss of goods (products) from the rear side of the demonstration surface, which simplifies the process of loading the demonstration surface with goods, and also reduces (compensates) possible impacts from the rear (back) side of the demonstration surface on the front surface of the refrigerated display case during the movement of the demonstration surface.

Also, according to an embodiment of the proposed utility model, the brackets are interconnected by a stabilizing jumper, which increases the rigidity of the shelf structure, simplifies the process of fixing the brackets in the refrigerated display case, and stabilizes the movement of the display surface.

Also, according to an embodiment of the proposed utility model, a technological hole is made in the stabilizing jumper, which simplifies the process of cleaning and removing dust and dirt.

Also, according to an embodiment of the proposed utility model, surface amplifiers are located under the demonstration surface, and in the lower part of the internal bend of the retractable guide there is a support bend facing the middle of the demonstration surface, and on which the lateral edges of the amplifiers, the end edges of which are adjacent to internal bend of a sliding guide. This increases the rigidity of the display surface and resistance to the occurrence of warping of the display surface as a result of uneven and unbalanced placement of goods on the display surface.

Also, according to an embodiment of the proposed utility model, the slip pad is made of a material with a coefficient of friction against steel of not more than 0.35, for example, PE 500. This reduces friction and accordingly reduces the load for moving the demonstration surface, and this material is also resistant to low temperatures, moisture and corrosion.

Also, according to an embodiment of the proposed utility model, a longitudinal channel is made in the upper part of the slip lining along its center, with protrusions formed on the lateral longitudinal sides thereof. The use of the longitudinal channel reduces the friction of the slip lining on the sliding guide, which causes a decrease in the effort to move the demonstration surface.

Utility Model Implementation Example

In FIG. 1 shows a sliding demonstration surface 1, in the rear side of which a rear stopper 1 _{1 is made} in the form of a U-shaped profile facing from surface 1. Rear stopper 1 ₁ prevents the loss of products located on surface 1 during the loading (placement) and unloading of products on surface 1 and in the process of moving it.

In the rear end surface of the brackets 2 made means of fixing 2 ₁ brackets 2 in the refrigerated display case. The lateral stops 9 of the surface 1 are located _{on the} sides of the front end surface 1 _2. The lateral stops 9 in the process of moving the surface 1 interact with the surface of the adjacent (nearby) side panels of the refrigerated display case, or with the side surface of the neighboring display shelf and thereby establish a certain distance, preventing damage side panels of the refrigerated display case and adjacent shelves.

In FIG. 2, the surface 1 is located in the extended position and moves along the slip plates 3. The brackets 2 are connected by a stabilizing jumper 4 made with a technological hole 4 ₁ , which simplifies the cleaning of the jumper 4 from dust and dirt. The jumper 4 increases the rigidity of the structure, simplifies the fixation of the brackets in the refrigerated display case, stabilizes the movement of the display surface.

In FIG. 3-5 shows the demonstration surface 1, separated from the brackets 2. In the upper part of the brackets 2 made guide limb 2₂facing the middle of the surface 1. On the guide bends 2₂ along their upper surface is a slip pad 3. Under the surface 1 are its amplifiers 5, made in the form of bent profiles, the lateral end edges of which are adjacent to the internal bends 6₂ and rely on the internal limb 6₃. The tipping limiter 7 is located on the rear side of the surface 1 at the end of the sliding guide 6 behind the inner limb 6₃. In this case, the upper surface of the tipping limiter 7 is located below the guide 6. The restrictive stop 8 of the extension of the surface 1 is located on the lower surface of the supporting limb 2₂.

In FIG. 6-8, for illustrative purposes, the dashed lines show a slip pad 3 along which the sliding guide 6 moves. The tipping stop 7 is located so that its upper surface is located under the guide bend 2₂brackets 2 and the upper surface of the limiter 7 moves along the guide bend 2₂, this prevents the surface 1 from tipping over, since the upper surface of the limiter 7 is in contact with the lower surface of the guide bend 2₂. Moreover, since the limiter 7 is fixed at the end of the sliding guide 6, which allows you to start the limiter 7 under the guide limb 2₂that allows you to easily remove or install surface 1 on the brackets 2 pre-installed in the refrigerated display case without using a special tool. In the process of moving the surface 1, the front end surface of the tipping limiter 7 interacts with the limit stop 8, thereby preventing the full extension of the surface 1 and its tipping. Using the limit stop 8, the extension length of the surface 1 can be adjusted, i.e. adjust the lever (force) from tipping over the surface 1. When using the proposed utility model, it is possible to simply place the limit stop 8 in the guide bend 2₂.

In FIG. 9 and FIG. 10 shows the slip pad 3 located on the upper surface of the guide bend 2 ₂ facing the middle of the surface 1. On the slip pad 3 rests the guide surface 6, on the sides of which two bends outer 6 ₁ and inner 6 _{2 are formed} , which prevent the horizontal movement of the guide surface 6 from the slip pad 3. In the lower part of the internal bend 6 ₂ , a support bend 6 _{3 is made} facing the middle of the surface 1. The end edges of the amplifiers 5 of surface 1, the end ₁ are supported on the support bend 6 ₃ whose ends are adjacent to the inner limb 6 ₂ . This increases the rigidity of the surface structure 1 and prevents its warpage while maintaining the simplicity of its manufacture and low material costs. Between the upper surface of the tipping limiter 7 and the lower surface of the guide bend 2 ₂ a gap is formed, which simplifies the installation of the surface 1 on the brackets 2 and provides acceptable play between the guide surface 6 and the slip plate 3 _. In the upper part of the slip lining 3, a longitudinal channel 3 _{1 is} made at its center _, on two sides of which two longitudinal protrusions 3 _{2 are formed,} along which the guide surface 6 moves. This allows to reduce friction between the slip lining 3 and the guide surface 6, which simplifies the process of moving surface 1.

In FIG. 11 and FIG. 12 shows how the front surface of the tipping limiter 7 interacts with the limit stop 8, which prevents the full extension of the surface 1 and its tipping. Using the limit stop 8, the extension length of the surface 1 can be adjusted, i.e. adjust the lever (force) from tipping over the surface 1. When using the proposed utility model, it is possible to simply place the limit stop 8 in the guide bend 2 ₂ .

In FIG. 16 and FIG. 17 shows the surface 1, in the rear of which there is a rear stopper 1 _1, made in the form of a U-shaped profile that faces from the surface 1. The sliding guide 6 is located at the same level with the stopper 1 ₁ , which increases the rigidity of the surface 1 ₁ and reduces the load when interacting with the front surface of the refrigerated display case.

In FIG. 16-20 shows a sliding surface 1. On the sides of the surface 1 are extendable rails 6, on the sides of which two bends are formed, the outer 6 ₁ and the inner 6 ₂ . In the lower part of the internal bend 6 _{2 there} is a support bend 6 ₃ facing the middle of the surface 1. On the support bend 6 _{3 the} free ends of the amplifiers 5 of surface 1 are supported, the end edges of which are adjacent to the internal bend 6 _{of the} guide 6. The amplifiers 5 of surface 1 are located under demonstration surface 1. at the back surface of the rear stopper 1 is 1 ₁ embodied as a U-shaped profile facing away from the surface 1. Since the sides of the rear stopper 1 ₁ are arranged slide rails 6, which is sprayed ozheny with him on the same level. Also, in the rear (back) side of the surface 1, on the support bend 6 ₃ , the tipping limiter 7 of surface 1 is fixed. The upper surface of the tipping limiter 7 is located below the guide 6, and the lower surface of the tipping limiter 7 is at the level of the reference limb 6 ₃ . The front end side 1 _{2 of} surface 1 is bent, removing the sharp edges of surface 1 from the zone accessible to the hands, as well as to hide structural parts and moving mechanisms of the shelf and provide the possibility of placing price tags, lights (not shown in the figures).

In FIG. 21 shows a refrigerated display case 10. On the front surface 10 _{1 of the} refrigerated display case 10, in its lower part, a sliding shelf is installed according to the proposed utility model, while on its display surface 1 there are goods 11. Surface 1 is mounted on brackets 2, which are fixed in the front surface 10 _{1 of the} refrigerated display case 10.
