Abstract
Description
- The present invention relates to a closure assembly applicable to a cooling equipment, capable of enabling simple mounting and dismounting of one of more covers.
- The use of cooling equipments is common both in commercial environments as in residential environments. Basically, the cooling equipments have as objective food products storage, preserving them at a temperature to prolong their useful life and to keep their quality.
- Residential cooling equipments have basically two compartments, known as refrigerator and freezer. The refrigerator usually has larger dimensions in comparison with a freezer, having an average storage capacity of 300 liters and operating at an average temperature of 3°C, while the freeze operates at average temperatures of -12°C and storage capacity of 70 liters.
- On the other hand, commercial cooling equipments are normally arranged in convenience networks, supermarkets, restaurants, drugstores, among others, and, unlike residential equipments, which basically may have both horizontal (chest freezer) and vertical shapes, the choice depending only on the need and desire of the client. Anyway, regardless of the shape of the product, the objective of the cooling equipment is always the same, that is, preserving the product inserted into it, thus prolonging its useful life.
- Unlike residential equipments, most of commercial equipments have only one compartment for products storage; however the storage capacity thereof is quite variable. An equipment of average capacity of 170 liters is considered small, while one of 550 liters storage capacity is considered large.
- Further, in comparison with residential cooling equipments, commercial equipments have the difference of being capable of operating at wider temperature ranges in only one compartment. For instance, as already mentioned, residential equipments have two compartments, the refrigerator and the freezer, each compartment being capable of reaching a given temperature, the freezer being capable of reaching lower temperatures in comparison with the refrigerator. On the other hand, most of the commercial cooling equipments are composed of only one compartment and, depending on the model the equipment can operate as a refrigerator (operation temperature range from 2°C to 8°C), as a freezer (operation temperature range from -15°C to -22°C) and even as refrigerator and freezer at the same time, thus being capable to operate at temperatures ranging from 2°C to 8°C and from -15°C to -22°C. The product operation temperature, as well as its storage capacity, depends only on the need of the client and on the type of product (beverages, foods, ice, ice-cream, among others) which is stored in the cooling equipment.
- Among the commercial equipments, one stands out by the use of horizontal freezers, also known as chest freezers, this type of equipment being composed basically of a rectangular cooling cabinet, having on its top surface at least one cover fixed to the cabinet frame.
- It is noted that the cover is responsible for performing thermal insulation, thus keeping the internal temperature at a desired level. Moreover, the cover is made preferably of a colorless or transparent material such as glass, thus enabling the food inserted into the cooling cabinet to be viewed without the need to open the cabinet and preventing unnecessary heat exchange between the cooling cabinet and the external environment.
- As it is natural in a commercial equipment that contains products to be consumed, it is necessary to provide it with an impeccable appearance and, for this reason, the cover that separates the consumer from the cooled product should be kept clean.
- During the life cycle of a horizontal freezer, there is therefore the need to remove the cover sometimes, for instance, for performing maintenance and cleaning of the cooling cabinet, or even for repairing the glass cover, which may undergo some kind of damage, thus requiring replacement. In the event of cover removal, it will always be necessary for the whole process from removal until replacement thereof to take place safely and within a reduced time.
- In the case of prior art horizontal freezers, the cover is fixed directly to a profile, usually made of plastic, which in turn is also fixed directly to the cooling cabinet. In other words, the cover is coupled to the plastic profile by means of fixing elements such as, for example, screws, rivets or glue/silicone and, in the same way, the plastic profiles are coupled to the freezer cabinet by using the same fixing elements.
- Thus, in the prior art technologies, if a cover removal is required, the plastic profile should be firstly removed and then the cover. This way, whenever there is the need to remove and/or change the cover of a horizontal freezer, the employee in charge should have adequate tools for performing such operation and, as in most cases, the fixation is made by using screws, and the employee should remove one screw at a time and then remove the cover altogether. This makes the cover removal process time consuming and exhaustive and still there is the possibility that the operator gets hurt during the process, or that the freezer undergoes some damage due to incorrect handling of the tools used by the employee.
- Optionally, there are some prior art solutions that make use of an additional profile (for example, a metallic one), the function of which is to fix the glass to its frame, having this profile a baguette-style function. Although this solution presents a more simple construction, the removal and replacement of the additional profile is toilsome. One of the drawbacks of this solution is due to fact that the user removes the glass without employing adequate tools, often using his nails or fingertips to remove the additional profile. Many of these situations cause injuries or cuts to the user, thus not providing a solution to the problem of removing and replacing the covers of commercial freezers.
- Therefore, it is not known in the prior art, a closure assembly for closing one or more covers, preferably for use on commercial freezers, which does not require the use of fixing elements for coupling the cover to the profile or frame, so that the removal and/or replacement of the cover will take place more rapidly, more efficiently and in safety, without any need for the operator to employ adequate tools to perform the operation, which may result in injuries to the operator and damages to the cooling equipment.
- Further, it is not known in the prior art any cooling equipment, more specifically commercial equipment that has a closure assembly for one or more covers and that uses the refrigerator profile/frame itself to couple the covers, the fixation thereof being performed without using any additional fixing element.
- The present invention has as objective the provision of a closure assembly for one or more covers, which does not need to use fixation elements for coupling the cover to the plastic profile of the refrigerator.
- The present invention has also the objective of providing a cooling equipment composed of a closure assembly for closing one or more covers, which uses only the profile itself of the cooling equipment to fix the covers responsible for the thermal insulation.
- It is also an objective of the present invention to provide a closure assembly for one or more covers, in which the cover removal procedure from a cooling equipment will be rapid, efficient and safe.
- The objectives of the invention are achieved by means of a closure assembly with the features of
claim 1. The closure assembly is applicable to a cooling equipment comprising a cabinet, the closure assembly being provided with first profile and second profile arranged in opposition in the cabinet sidewalls, the cabinet being covered by at least one cover arranged between first and second profiles, wherein the first profile comprises at least one first recess defining and the second profile comprises at least a second recess, each recess defining a limited aperture through a first face and a second face, the first and the second faces of the recesses being arranged by means substantially orthogonal with respect to the cabinet sidewalls; each aperture defining a spacing for housing the cover, the innermost portion arranged between the first face and the second face of at least one of the recesses defining an aperture that is smaller at the outermost portion arranged between the first and second faces, the cover being slidingly housed between the recesses, wherein the movement of the cover is limited by the smaller aperture of at least one of the recesses. - The objectives of the invention are also achieved by means of a cooling equipment with the features of claim 9, this cooling equipment having a closure assembly as mentioned above.
- The present invention will now be described in greater details with reference to an example of an embodiment represented in the figures. The figures show:

Figure 1 shows a perspective and cross-sectional view of a possible configuration applied to acooling cabinet 16 having theclosure assembly 1 of the present invention. Preferably, but not compulsorily, thecabinet 16 is of the horizontal type, which is also called chest freezer, being closed by means of two covers 12 responsible for providing thermal insulation of thecabinet 16. Alternatively, thecabinet 16 may be closed by one, three ormore covers 12 arranged over each other, and thecabinet 16 may be both horizontal or vertical. - It is noted that a
cabinet 16 may be constructed from two or more overlapped sliding foils, each foil being provided with itscovers 12. Thus, in order to access the interior of thecabinet 16, suffice it to slide one foil over the other. Alternatively, thecabinet 16 may be provided with only one foil with itsrespective cover assembly 12, the foil being pivotable to one of its ends, so that upon pulling the foil at the opposite end, the foil opens and enables access to the interior of thecabinet 16. - The dimensions of the
covers 12 are directly related to the dimensions of thecabinet 16 and may be totally planes or slightly angulated, depending only on the need of the client and of the developed design on the refrigerator. In this embodiment, thecovers 12 are preferably colorless or transparent and made of glass, thus enabling the user to view the internal compartment of thecabinet 16 altogether. Alternatively, the covers may be made of acrylic, or even from a material that has translucency characteristics on thecovers 12. - As shown in
figure 1 , thecabinet 16 comprises afirst profile 3 and asecond profile 2, which are arranged in opposition to each other at the ends of thesidewalls 50 of thecabinet 16. Thus, thecovers 12 are arranged between the first and thesecond profiles covers 12 of the present invention is made due to the relation of thecover 12 with the structural embodiment of thefirst profile 3 and of thesecond profile 2. -
Figure 2 represents a cross-sectional side view pointing out theclosure assembly 1 of the present invention in an embodiment wherein thecovers 12 are in place, showing the arrangement of thecovers 12 during normal operation of the cooling equipment. - As shown in
figure 2 , thefirst profile 3 comprises at least one first recess 4 and thesecond profile 2 comprises at least onesecond recess 7. It should be stressed that the number of existing recesses are directly related to the number ofcovers 12 employed on thecabinet 16. In this way, for eachcover 12 there will be tworecesses 4, 7, in other words, considering that thecover 12 is supported by two of its sides, tworecesses 4, 7 percover 12 will be necessary. - Each of the
recesses 4, 7 define a respectivelyaperture apertures first profile 3 and on thesecond profile 2. Each aperture is like a groove, so that anaperture 14 is limited byfirst face 24 and by second face 24', which are arranged substantially orthogonal to thesidewalls 50 of thecabinet 16. Similarly, theaperture 17 is limited byfirst face 27 and by second face 27', which are arranged substantially orthogonal to thesidewalls 50 of thecabinet 16, the same thing happening for each existing recess on the coolingcabinet 16. It should be noted that the expression "substantially orthogonal to thesidewalls 50" embraces a variable angle between the first and second faces 24, 24', 27, 27' of therecesses 4, 7 with respect to thesidewalls 50 of thecabinet 16, which enables them to be defined by angles ranging from 90 to 125 degrees. - As described, each
aperture cover 12, the twoapertures covers 12, therecesses 4, 7 may share adjacentinternal faces - In a preferred embodiment shown in
figure 5 , the innermost portion between thefirst face 24 and the second face 24' defines a smaller dimension or width D1 than the outermost portion, the inlet portion ofcover 12, of smaller dimension or width D2, arranged between thefirst face 24 and the second face 24'. - In this preferred embodiment of the
closure assembly 1 described in the present invention, the second face 24' further comprises a protrudingtooth 100, arranged inside the first recess 4, the protrudingtooth 100 being responsible for preventing thecover 12 from displacing horizontally in the inner portion of the first recess 4, since the latter acts like a displacement limiter for thecovers 12. Although in this preferred embodiment of theclosure assembly 1 the protrudingtooth 100 is arranged on the second face 24' of the first recess 4, the protrudingtooth 100 could be arranged on thefirst face tooth 100 should be arranged on therecesses 4, 7 of only one of theprofiles cover 12 after its housing. The protrudingtooth 100 further performs an important role during the removal process of thecovers 12, which will be described in greater detail along this description. It is noted that the existence of thetooth 100 that configures a smaller dimension or width D1 of the recess 4. - As it is clear, this embodiment prevents the
cover 12 from displacing horizontally during the normal operation of the cooling equipment, since thecover 12 remains substantially fitted into therecesses 4, 7, and limited on one side by a bottom wall of arecess 7 and, on the other side by an existing protrudingtooth 100 in the analogous recess 4. - Alternatively to the structural embodiment of the protruding
tooth 100, the first and the second faces 24, 24', 27, 27' could have concurrent profiles, thus defining one of therecesses 4, 7 in the form of a wedge. By "concurrent traces" one means that the concurrence point between the first and the second faces 24, 24', 27, 27' occurs at the innermost portion of one of therecesses 4, 7, enabling the innermost portion to have a smaller dimension or width D1 than the innermost portion of larger dimension or width D2. - Further, it is important to point out that, just as the number of
recesses 4, 7, the number ofapertures closure assembly 1 of the present invention are directly related to the number ofcovers 12 employed in the isolation of the coolingcabinet 16. - A preferred structural embodiment of the
closure assembly 1 having been described, which comprisesfirst profile 3 andsecond profile 2, the other figures of this specification have the objective of showing how the present invention enables the removal ofcovers 12. - As already mentioned before,
figure 2 shows the arrangement of thecovers 12 during normal operation of the cooling equipment, and in this embodiment thecover 12 is arranged over the second faces 24' and 27' of theapertures - Since in this preferred example two
covers 12 are employed to provide thermal insulation of the coolingcabinet 16, if it is necessary to remove thecovers 12, one should first remove theupper cover 12 and then thelower cover 12. - As shown in
figure 3 , in order to remove theupper cover 12 through theclosure assembly 1 of the present invention, one should first displace it horizontally toward the protrudingtooth 100, and then raise it to a height corresponding to the height of the protrudingtooth 100 and overlap thecover 12 to the protrudingtooth 100. It is noted that the protrudingtooth 100 has such height that prevents inadvertent displacement of thecover 12 over the protrudingtooth 100. - Subsequently, one should push the
upper cover 12 horizontally toward thefirst profile 3, thecover 12 will come into contact with the end portion of theaperture 14, thus reaching the end limit of its horizontal displacement. In this way, upon displacement of theupper cover 12 horizontally until it comes into contact with the end portion of theaperture 14 of thefirst profile 3, the surface of thecover 12 that was in contact with the second face 27' of thesecond profile 2 before will also displace horizontally toward thefirst profile 3, thus causing loss of contact between thecover 12 and the second face 27'. - Thus, the worker in charge of removing the
upper cover 12 may then raise by its free side, since thecover 12 is no longer limited to thefirst face 27 of thesecond recess 7 of thesecond profile 2, as shown infigure 4 of the present patent application. Then, the worker should pull theupper cover 12 toward thesecond profile 2, and theupper cover 12 will be removed altogether, as shown infigure 5 . - The process for removing the
upper cover 12 through theclosure assembly 1 of the present invention having been described, one repeat the same steps for removing thelower cover 12. In this way, thecovers 12 are removed easily and securely, without the need to employ tools that might cause injuries to the worker, which results in greater efficiency and safety during the process of removing thecovers 12 of a cooling equipment . - In the same way as the
covers 12 were removed from the coolingcabinet 16 by using theclosure assembly 1 of the present invention, thecovers 12 can be inserted again into the coolingcabinet 16, without the need to employ tools, it being sufficient to proceed as described in the present patent application, but in reversed order. - One should point out the fact that the
cover closure assembly 1 described in the present patent application should be preferably but not compulsorily employed on horizontal cooling equipments, the so-called chest freezers. However, nothing prevents thecover 12closure assembly 1 from being used on vertical cooling equipments or any other equipment - whether a cooling one or not - that employs covers, whether made of glass, plastic, fiber or any other material - for isolate a given surface of the equipment. It is sufficient to provide the equipment withfirst profile 3,second profile 2 and a cover having the constructive characteristics of the present invention. - It should be reminded that the
