Description

"DESARMABLE DESKTOP THAT IS SAVED IN A CASE" FIELD OF THE INVENTION The present invention is related to the techniques used in the manufacture and design of furniture, displays and counters used in places known as "points of sale", where products and services are offered to the public, and more particularly, is related with a removable desk that is kept in a case.

BACKGROUND OF THE INVENTION In many places where the public is concentrated to acquire and disseminate products and services, such as exhibitions, conventions, information centers, shopping centers, electoral voting modules, etc., it is a necessity to use furniture, exhibitors and many Sometimes desks for the public to make contact with suppliers, know the products and order them. In this sense, there is a great variety of these furniture, there are wood, metal, with shelves, divisions, but in general they are difficult to maneuver, and the transportation of them is an arduous task, since they are heavy and not they allow to place different objects. Most conventional desks are not collapsible and therefore storage and transport is extremely complicated. A solution known in the prior art for these problems has been the creation of folding and collapsible furniture and desks made of wood, metal and steel, however, these have the drawback of being very heavy and above all they are difficult to transport.

In recent years, the design of folding or collapsible desks has been focused to meet needs in offices and schools, and the vast majority of them are specially designed to place desktop computers, so that these desks have entries for cables of the computer, compartments and sliding platforms for the keyboard and cavities for the monitor. As these desks are supposed to stay in one place for a long time, they are looking for their parts to be firmly fixed, in other words, once the desks are armed, it is not contemplated to disarm them again. One of these desks is described in the U.S. patent. 6,082,838, which is characterized by being composed of a main structure consisting of three pieces joined together, two of which are arranged vertically and whose function is to serve as pedestals or legs of the desk, each of these pieces is located joined by hinges to a third piece placed horizontally, this serves as front of the desk, which is easy to store and does not require tools to assemble it; however, it does not cover the needs of the points of sale since it does not have a panel to place advertising and is attractive to the public. In the U.S. patent application U.S. 2004/0173124 A1 describes a folding desk exclusively for a computer and includes several shelves in which different items can be placed, however once it is folded its transport is not comfortable. Now, the activities typical of the "point of sale" sites mean that the furniture is only used for two or three days and then becomes saved, even in the same day, they have to be assembled in the morning and stored at night, so the easy assembly of these furniture should be a guideline for its design.

In the prior art, extremely useful furniture is known in the points of sale, such as the display modules that are kept in the form of a portfolio, of the same author as the one of the present invention and which are described in the Mexican patents No. 212,227; 225,710 and in the international patent application. No. PCT / IB2005 / 002083, however, the need to provide easily assembled desks and that when stored occupy little space has not been covered so far.

BRIEF DESCRIPTION OF THE INVENTION In order to solve the shortcomings of the prior art, the present invention is directed towards a collapsible desk that is kept in a case and which is composed of the following elements: a folding base formed by a first wall and a second wall joined articulately to the first wall; On said foldable base, a cover is fitted in the form of a housing and which also serves as the desk case. When the folding base is folded it is stored inside the cover. Another element of the invention is a leg that is removably attached to the lower part of the cover, preferably diagonally opposite the joining of the walls forming said folding base; the leg is also stored inside the cover; this leg together with the folding base support mainly the desk. The desk of the present invention also comprises a left wall which is laterally coupled to said cover and which extends upwards and downwards thereof, this left wall is formed by a lower half and an upper half which are coupled to each other and that are stored on the deck; similarly, there is also a right wall which laterally engages said cover and extends upwards and downwards thereof, wherein the right wall is formed by a lower half and an upper half which are coupled to each other and which are stored on the deck. The left and right walls increase the stability of the desk and also provide an extended surface that serves to place graphic material. Furthermore, on the desk of the present invention, there is a folding board that is mounted on the left wall and the right wall connecting them, this board being folded can be stored inside the folding base. To disarm and save the desk from its "armed" position, the folding board is disassembled and folded in half; then, the left and right walls are dismantled, their halves decoupled; the cover is uncoupled from the foldable base and inside the latter the folding board is stored and the folded base is then folded in half; likewise, the leg is dismounted from the cover inside which both the folded base, the leg and the halves forming the right and left walls are housed, thus achieving the "saved" position of the collapsible desk. In a preferred embodiment of the present invention, the desk has as optional elements a first and a second horizontal panel that are coupled together and that are coupled on the cover and which can also be stored inside the folding base together with the folding board . These panels are preferably transparent and help to improve the appearance of the desk giving a sense of privacy towards the back of it. The panels do not make it necessary to increase or modify the structure or the size of the foldable base nor that of the cover that serves as a case to house all the elements of the desk when it is stored. According to the above, an object of the present invention is to provide a collapsible desk whose parts are designed with a size such that they can be housed inside the desk cover.

Another object of the present invention is to provide a collapsible desk which, when in its "stored" position, occupies little space and can be easily transported.

DETAILED DESCRIPTION OF THE INVENTION With reference in particular to the accompanying drawings, and more specifically to Figures 1 to 3 thereof, they show a removable desk 10 that is kept in a case, the desk being constructed in accordance with a particularly preferred embodiment of the present invention, which should be considered only as illustrative, but not limiting thereof. The collapsible desk 10 of this preferred embodiment comprises in general terms: a foldable base 20 formed by a first wall 21 and a second wall 22 jointed hinged to the first wall 21 by a hinge not shown in the figures, in the position of Armed with the desk, the walls 21 and 22 of the foldable base preferably form a 90 ° square. Even on the surface of the walls 21 and 22, graphic material can be placed.

On said foldable base 20, a cover 30 that serves as a housing and with a preferred parallelepiped shape is removably coupled and also serves as the case where all the parts of the desk 10 are to be housed. For example, it can be mentioned that this point that when said base 20 is folded it has a size such that it can be stored inside the cover 30. On the back of the desk 10, there is a leg 40 that is removably attached to the bottom of the base folding 20; the leg 40 is preferably located diagonally opposite the junction of the walls 21 and 22 forming said foldable base 20. The leg 40 is of such size that it can be stored within the cover 30; this leg 40 together with the foldable base 20 mainly support the collapsible desk 10. In Figures 1 to 3, it can also be seen that the collapsible desk 10 comprises a left wall 60 that is laterally coupled to said cover 30 and extending towards up and down thereof, this left wall 60 is formed by a lower half 61 and an upper half 62 which engage with each other and which can be stored inside the cover 30. Similarly, there is also a right wall 70. which is laterally coupled to said cover 30 and extending upwards and downwards thereof, said right wall 70 is formed by a lower half 71 and an upper half 72 which are coupled to each other and which are stored in the cover 30. as will be explained and illustrated a little later. The left and right walls 60 and 70 project perpendicularly away from the desk and are opposite one from the other, preferably being arranged in opposite corners of the cover 30. On the surface of the left and right walls 60 and 70 can be placed graphic material such as posters, decals, cardboards, etc.

In the upper part of the desk 10, one can observe a folding board 80 that is mounted on the left wall 60 and the right wall 70 connecting thereto, this foldable board 80 when folded can be stored inside the foldable base 20 that in turn, it is stored in the cover 30. The folding board 80 is formed by four sections jointed one next to the other and identified with the numerical references 81 to 84, defining a left section 81, a right section 82 and two front sections 83 and 84 left and right respectively. In Figure 2, it can be seen that the left section 81 is hingedly joined to the front section 83 on the same side by the left hinge 85, while the right section 82 joins hingedly to the right section 84 by the right hinge 86; and the front sections 83 and 84 are hingedly joined together by the central hinge 87, which allows the board 80 to be folded and folded in half, while the left 85 and right hinges 86 give flexibility to the left 81 and right 82 sections. of the folding board 80. It should be mentioned that the hinges 85, 86 and 87 are preferably plastic hinges and are adhered to the back of the folding board 80, consequently, they can not be seen by the customers from the front of the desk 10. When the folding board 80 is assembled, it will allow to identify the provider of the services or products that are offered in the removable desk 10. In this preferred embodiment of the present invention illustrated in the accompanying drawings, the desk has as optional elements a first and a second horizontal panel 90 and 95 that are coupled to each other, preferably forming a 90 ° square and joined together e removably on the cover 30. These horizontal panels 90 and 95 have a size such that each of them individually can be stored inside the folding base 20 together with the folding board 80. The horizontal panels 90 and 95 are preferably transparent and help to improve the appearance of the desk 10 giving a sense of privacy towards the back of it, where the service or product provider and his client are supposed to be seated. In the subsequent Figures the way in which the desktop 10 is being disarmed will be shown. Specifically, from Figures 4, 4A, it is convenient to explain that each of the left and right sections 81 and 82 of the folding board is formed by a frame 88, preferably of rectangular shape, and a pair of plates 89 joined on the faces of frame 88 in the manner of a sandwich. Each of the left and right sections 81 and 82 includes a pair of coupling sections 88a provided on the side sides of the frame 88 and projecting downward from the foldable board 80. One of said coupling sections 88a, preferably that found at the free end of the left or right section 81 or 82 is slidable and runs internally within the lateral side of the frame 88, further includes a pin 88b that passes through perforations 88c provided in the frame 88. When the pin 88b is pressed, it is pressed. frees from one of the perforations 88c and allows the coupling section 88a to be moved within the frame so that it protrudes a greater or lesser length; the more protruding the coupling section 88a may be introduced deeper inside the upper half 62 or 72 of the left or right wall 60 or 70, thereby achieving better stability for the folding board 80 (see Figure 4A), where this detail is shown in the left section 81 of the folding board. In other words, the coupling between the folding board 80 and the upper halves 62 and 72 of the left and right walls 60 and 70 is achieved because the coupling sections 88a are received within the corresponding upper half 62 and 72. The folding board 80 is disassembled from the walls 60 and 70 by pulling it upwards, once the folding board 80 has been disassembled, it is folded in half to reduce its size by half, remaining in the position illustrated in FIG. Figure 5, in which each of its sections 81 to 84 can be identified, the hinges 85 to 87 hingedly joining said sections; the frame 88 of the left section 81 and the right section 82, the plates 89 covering the faces of the corresponding frame 88 and the coupling sections 88a. Reference is now made to Figures 6, 6A and 6B, where the desk 10 is already shown without the folding board and with the left and right walls 60 and 70 being removed. As mentioned, the left wall or the right wall 60 and 70 are formed by a lower half 61 or 71 and an upper half 62 or 72 that engage with each other. In the preferred embodiment described, both upper halves 62 and 72 are formed by an upper frame 63 or 73 with one preferably rectangular in shape whose lower part has a shape such that it engages the outline of the upper part of the cover 30. In addition, the upper halves 62 and 72 include plates or sheets 63a and 73a that line both sides of the upper frame 63 and 73. However, the upper halves 62 and 72 include a coupling post 64 and 74 attached to the inner side of the upper frame. its frame 63 or 73 and also include a coupling portion 65 and 75 attached to the lower part of the outer side of frame 63 or 73 and projecting downwardly thereof. The frame 63 or 73 of each upper half and its coupling post 64 or 74 are hollow, so that at its upper end the coupling sections 88a of the left or right section 81 or 82 of the folding board 80 are received (see figure 4). And on the other hand, the lower side of the coupling post 64 or 74 is coupled to the first and second horizontal panels 90 and 95, as shown in the detail of Figure 6A for the case of the upper half 72 and the second half. 95 horizontal panel.

For its part, the coupling portion 65 and 75 of the upper halves 62 and 72 is inserted into the lower half 61 and 71 of the left and right wall 60 and 70 respectively, for this each of said lower halves 61 and 71 it is formed by a lower frame 66 and 76, preferably rectangular and hollow, and which in its upper part is coupled in shape to the lateral and lower contour of the cover 30. In each lower frame 66 and 76 there are adhered sheets 66a and 76a of such that the lower frame 66 or 76 is between them in the manner of a sandwich. Another important feature in the present invention is related to the fact that the walls 60 and 70 are fixed to both the cover 30 and the foldable base 20. Particularly, the upper half 62 or 72 of each wall 60 and 70 includes first means of fixing, which in the embodiment described are the bolts 67 and 77 that are received in cooperating holes 51 provided in the upper part of the cover 30 (See Figure 6B). In order to fix said upper halves to the cover, the bolt 67 or 77 is inserted inside the cover 30 and when the lever 68 or 78 is moved, the bolt 67 or 77 is caused to move laterally inside the cover 30 with respect to the Initial position that it had when it was introduced, so it can not be removed through the hole 51, causing the upper half 62 or 72, as the case may be, to be fixed to the cover 30. Other means of fixation can be used such as sailboat portions, male-female couplings, etc. Similarly, the lower half 61 or 71 of each wall 60 or 70 is fixed to the foldable base 20, for which the lower halves 61 and 71 include second fixing means, which are bolts 69 and 79, whose characteristics are identical to the bolts 67 and 77 previously described and introduced into cooperating holes 29 provided in both walls 21 and 22 of the folding base 20. In Figures 7, 7A and 7B the collapsible desk 10 is already shown without its left and right walls and with the horizontal panels 90 and 95 being disassembled, in the embodiment described, these horizontal panels 90 and 95 are formed by a pair of coupling side posts that in the panel 95 are identified with the reference 91 and in the panel 95 with reference 96, a frame 92 or 97 fixed between both side posts and a sheet 93 or 98, supported within the respective frame 92 or 97, the sheet is preferably made of a transparent material such as acrylic or polycarbonate or, etc. For coupling the horizontal panels 90 and 95 to the cover 30, the latter includes three recesses identified with the reference 31 formed on its upper face, in said recesses 31 the two coupling side posts 91 of the first panel 90 and one of the coupling side posts 96 of the second panel 95, the other coupling side post 96 of the second panel 95 is received within the upper part of one of the coupling posts 91 of the first panel 90 whereby both panels 90 and 95 are coupled each other in the manner of a 90 ° square, this detail can be seen in Figure 7A. To uncouple horizontal panels 90 and 95 from cover 30, both need only be moved upwardly (see Figure 7B) and then uncouple panels 90 and 95 from each other as in Figure 7A. In Figure 8, the disassembly of the cover 30 of the foldable base 20 is presented which is achieved with an upward movement, in this Figure 8 it can be seen the leg 40 that is mounted to the cover 30 and that is diagonally opposite to the joining of the walls 21 and 22 forming the foldable base 20. Now, reference is made to Figures 9 and 10 to describe the manner in which the leg 40 is mounted to the cover 30 and how it is disassembled therefrom. . When the desk is armed, the leg 40 is mounted to a mounting base 41 provided inside the cover 30, the mounting base 41 is preferably a piece of an elastic material like the rubber and includes a central screw 42 projecting from the mounting base 41 and wherein the leg 40 is screwed or unscrewed. Of course other means and ways to mount the leg 40 to the cover 30 would be possible, for example by means of male couplings, sailboat®, however, the form described for the preferred embodiment is very practical. The leg 40 can be made of a metallic or plastic material and has a size such that when disassembled it can be housed inside the cover 30, which has its own structure for the purpose of housing the folding desk elements. The cover 30 is in the form of a parallelepiped-shaped housing having two side faces 32 and 33, a lower face 34 and a cover 35 hingedly attached to the cover by a longitudinal hinge 36, each of the side faces 32 and 33 , the lower face 34 and the cover 35 additionally include a flange identified respectively with the references 52, 53, 54, and 55 projecting inward from the cover 30 and being parallel to the surface thereof. The side flange 52 and the flange 54 of the lower face 34 together form an internal perimeter border 37 that fits in size and shape to the upper edge 23 formed by the walls 21 and 22 of the foldable base 20 (Figure 11), this has a function since the cover 30 being mounted on the base avoids lateral displacements of the same. In addition, the other side flanges, ie the flange 53 and the flange 55 of the cover 35 include a cut in the shape of a half circle identified with references 56 and 57; when the lid 35 is closed, said cuts 56 and 57 form a gap that is pierced by the leg 40 that is received and screwed to the mounting base 41. With the exception of the cover 35, the rest of the cover 30 is formed in one piece, preferably from a foamed PVC sheet. On the other hand, the cover 35 is provided with lock means, which in the embodiment described are the retractable pins 38, which in their "closed" position pass through a side hole 39 provided in each lateral face 32 and 33 of the cover 30. The closure of the cover 35 is carried out in two situations, the first is when the desk is fully armed to keep the leg 40 fixed and inside the gap formed by the cuts 56 and 57, and the second is when all the pieces of the desk are stored inside the cover 30. Other lock means such as locks, snaps or padlocks can also be used so that the cover 35 is fixed on the rest of the cover 30. Now, reference is made to Figure 12 for describe the manner in which the folding board 80 and the horizontal panels 90 and 95 are stored within the folding base 20, which as mentioned comprises a first wall 21 and a second wall 22, each of These walls is formed by a perimeter frame that is identified with the references 25 and 26, a sheet 25a or 26a that covers them and an internal frame 27 and 28, which has the function of housing the folding board 80 when it is stored . Furthermore, said internal frames 27 and 28 increase the structural strength of the foldable base 20. On the other hand, the panels 90 and 95 are stored one in the first wall 21 and another in the second wall 22 placing them within the remaining space of the perimeter frame 25 or 26 that is not occupied by the internal frame 27 and 28. Once the panels 90, 95 and the folding board 80 are placed within their corresponding space of the folding base 20, the first wall 21 moves on the second one. wall 22 enclosing the folding board 80 and both panels 90 and 95. In Figure 13, the manner in which the lower halves 61 and 71, the upper halves 62 and 72, the collapsible base 20 and the leg 40 are shown in FIG. preferably being stored inside the cover, as seen the lower and upper halves 61, 71, 62 and 72 are placed vertically side by side and on the cover 30, there is no specific order for this purpose since All of these elements fit perfectly within the cover 30. Figure 14 shows the manner in which the lower halves 61 and 71, the upper halves 62 and 72 and the leg 40 are stored inside the cover 30, so In particular, all the lower and upper halves are placed on the foldable base 20, while the leg 40 is stored between the foldable base 20 and the mounting base 41. In Figure 14 the lid 35 is open, which must be closed and securing over the rest of the cover 30 with the retractable pins 38. Figures 1 A to 14C show the operation sequence of one of the retractable pins 38 that serve to close the cover 35, particularly the one that is operated in the lateral face 32 of the cover 30, the retractable pin 38 is operated externally by means of a lever 50 which when moved from one side to the other causes the retractable pin 38 to pass through the lateral hole 39, thereby the lid is closed and the "stored" position of the desk 10 is finally achieved as shown in Figures 15 and 16. In the present invention, means are provided for grabbing the cover, which in the embodiment described is handle 11 attached on the cover, in particular the handle 11 is joined in the center of the cover 35; the handle 11 can be taken by hand to move the entire desktop 10 already saved. Another means of gripping the cover may be a strap whose ends are attached to both side faces 32 and 33 of the cover 30. As noted, the desk 10 in its "saved" position shown in Figures 15 and 16 has a compact structure and therefore occupies little space and on the back of the desk 10 only lower and upper halves 61, 62 can be noted, 71 and 72 of the walls of the desk. The desktop of the present invention has very suitable dimensions to be used in the "point of sale" sites, for example, and without this representing a limitation, it can be mentioned that it has a typical height of around 1.70m to 2.00m.; the roof is separated from the floor at a height of 0.80 to 1.00m; the deck measures approximately 80cm on each side. at 1m whereby a large work surface is obtained; and the left and right walls extend outward from the desk in about 20 to 30cm. approximately. These dimensions are preferred, since the most important thing for the invention is the peculiar shape of the coupling between its parts and that when being disassembled the pieces of the desk can be housed inside the cover. With regard to its weight this does not represent any inconvenience since all parts of the desk, such as frames and plates are preferably made of polymeric materials such as PVC. As it has been observed, the structural relationship between the elements of the folding desk allow them to be saved in a very compact way, so that it can be used in an infinity of applications, being its main use in the sites "points of sale". Even though a preferred embodiment of the present invention has been described and exemplified, it should be emphasized that numerous modifications to it are possible, such as the type of hinges used, the manner of mounting the leg to the cover and the dimensions of the hinges. the elements of the desktop. Therefore, the present invention should not be considered as restricted except by what is required by the prior art and by the scope of the appended claims.
