IMPROVEMENT TO PROTECTION COVERING OF PARALLELEPIPEDAL PANELS
The present invention relates to a particoular improvement expecially brought to protection covering of parallelepipedal panels normally constituted by idoneous parallelepipedal boxes obtained in a particoularly cardboard suitable for the puropose, said improvement essentially consist in a particoular conformation brought to the strips of the contrapposed edges resulting to the extremity of the two parts that normally are employed for the closure of a relative box and a successively simple fixing of said two strips by a normal glue.
It is known that particoularly in the industrial production of furnitures, the various elements resulting represent a conformation sustantially parallelepipedal as cupboards, cabinets, and similar, are obtained simply assembling relatives various parallelepipedal panels more or less elaborated wether on their surfaces then on thei structures, that are produced in series in big quantity from the same company that produces them or from several specialized companies specialized in the production of single particoular elements as panels, special work plates and others.
All this happens expecially in the industrial production of kitchen furniture where nearly to the totality of the elements forming the furnishing of a kitchen are constituted by elements called "modulars" all formed from parallelepipedal elements.
The single parallelepipedal panels at the end of the various operations done for their production must be, for first, opportunely piled then they must be transported and stocked temporaneously more time before to arrive to their final destination.
Obviously, sayd panels during their various movements can suffer impacts and scratchs that can damages the panels with abrasions, scratchs or wether the real breaking of thems.
As well as known, in the way to avoid this drawback, the single panels as soon as are finished are placed in idoneous protection covering constituted pratically by relatives parallelepipedal boxes normally done in cardboard, normally a "corrugated board".
The boxes that normally are in the most part used for the above mentioned finality, are fundamentally constituted, as above mentioned, from relative parallelepipedal boxes one of the bigger faces of which, it results,usually, divided longitudinally in two parts, usually simmetrical between them. After the insert in said boxes, of the relative parallelepipedal panel (or other equivalent) it is closed in the whole applying on the two longitudinal edges
between them closer of the correspondant two parts in which is divided longitudinally the relative bigger face, a normal adhesive tape in plastic material.
The application of said tape can be executed by using opportune machines. The use of this first method, i.e. that using the normal procedure, presents various difects and has various drawback. First, it needs personnel, that means consequently relative costs and furthermore this operation need a certain attention and accuracy to obtain an agreable result. Wether all this, the precision and the regularity of the placement of the adhesive tape results always almost aleatory and consequently producing only mediocre results that often results even insufficient. Also the necessary times for a normal esecution of this operation results always elevated and then results elevated the incidence costs too.
Instead the use of the second method, that involving operative systems of mechanic type, i.e. machines that mades the operation of application of the adhesive tape in a fast and sure way, let alone to make the filing and consequent adhesion on the relative surface with hight precision and regularity, presents it too various drawback and difects. First the machines used in this secon method needs of frequent substitution of the rolls of adhesive tape that requires relative intervents giving consequently much "machine stops" as the intervents with relative stops that often needs more time because of the various difficulties found during this intervents, for notable periods of time. Further to this, as is known it can verify casual breacks and jamming or irregularities in the positioning of said adhesive tape that obviously requires opportune intervents and consequent stops of said machines.
Clearly the drawback of said second method, here above mentioned, will be the cause of relative economical damages.
It is putted the attention on the fact that further to the various drawback only partially above mentioned, related specifically to the two different methods used for the application of the adhesive tape on the relative parts of the corresponding parallelepipedal boxes to obtain the reciprocal junction and fixing of the same, the drawback and the bigger difect common to both the above mentioned methods is the use of said adhesive tape. In fact, as well known, the material with which is made the adhesive tape is essentially plastic material then, when the boxes results at the end of their use they constitute relative composed garbage of cardboard but polluted by
the presence of plastic material for which the carry off cost is more than that of not polluting substances.
The object of the present invention is that to remedy to the various drawback and note difect, part of whch has been above emntioned and this is obtained with the particoular improvement brought to the boxes knewn and commonly used to protect relative parallelepipedal panels used principally in the field of the production of furnitures. For better understand the characteristics and the advantages that can be obtained with the present invention, the whole, in a preferred conformation and realizable way and in a way only exemplificative and not limitative is here consequently described with references to the enclosed drawings in which:
- the figure 1 showns with a perspective wiev, the development of an element able to form a relative parallelepipedal box of improved type by the present invention that results particoularly usable for the protection of relative parallelepipedal panels; the figure 2 showns the same element for the formation of the relative boxes showns in the previous figure 1 with the add of a relative panel placed on the same element; the figure 3 is a perspectical wiev of a box of the type doing object of the present invention, showings the same in a position partially open;
- the figure 4 showns as the figure 3 the same box but resulting completely closed; the figure 5 showns with an enlarged wiev the particoular putted in evidence in figure 4.
It is to relevate that in the above mentioned figures the common particoulars are reported with the same references.
With reference first to the figure 1, it is possible to note how the fundamental element 1 used to produce the relative parallelepipedal box S (to see figures 3 and 4) it has a conformation substantially equal to that used to produce a normal box ofthe same type. The new solution is different from the other solutions just known and diffused, only for the fact that in it, to obtain a normal parallelepipedal box the two half in which it is divided longitudinally a relative bigger face, rather than extend from the correspective lateral edges of respective bigger faces with two stretch, normally equal between them, it exthends with stretch opportunely
reasonably bigger in the way that the two respective free extremity can per superimposed between them reciprocally with two idoneous short stretch. For a better comprehension of the whole, over all the particoular conformation let alone the particoular function of the above mentioned short stretch that how above mentioned, they results at the free extremity of the respective two parts in which result longitudinally divided the realtive bigger face of a respective parallelepipedal box, then shall proceed to describe in detail the conformation and function of all the parts constituting the fundamental element 1. How is known, said fundamental element 1 will be obtained cutting it, with known might, from a relative sheet of cardboard,normally a sheet of corrugated cardboard type. Contemporaneously to the operation of cutting that fix his (1) perimetric conformation and consequently his various dimensions, are done, always with might and methods known, idoneous linear compressions producing corresponding "folding lines" L resulting able to permit to fold around to the same (L) the various parts to them (A) closer, for the formation of a relative parallelepipedal box. Always contemporaneously to the above mentioned operations, will be further done on the two edges (14a and 14b) resulting how consequently exponded at the two free extremity of the respective two parts (13a and 13b) in which results divided one of the two bigger faces of a relative parallelepipedal box S, opportune flattering or generate on said two edges (14a and 14b) corresponding thining in the opposite senses.
With reference always to figure 1 , is possible to relavate in the detail all the conformative particoulars of the fundamental element 1. Observing said figure 1 is possible to note how said fundamental element is composed by a central element 11 of rectangular shape constituting one of the bigger faces of the parallelepiped that forms the respective box S (see figures 3 and 4), from the bigger sides of which (1 1) departs two first lateral elements A and B also rectangular, while from his lesser sides departs two second lateral elements C always rectangular let alone normally equals between them. Said two first lateral elements A and B results divided in two internal parts and in two esternal parts. Said two internal parts results constituted by two correspondant "belts" 12a and 12b each one of which results laterally delimitated by respective couples of folding lines L of which, two internal that are corresponding to the relative bigger sides of the rectangle forming said central element 11 and two external. This first
couples of lines of folding results at a certain distance between them how is the thickness that results between the two bigger faces of the resulting parallepipedal box S increased of the thickness of the corrugate cardboard. The subsequent two external parts results instead constituted by relative belts 13a and 13b which departs from the respective precedent external folding lines L ending in the respective free extremity with idoneous edge 14a and 14b thining in opposed senses between them. Said two belts 13a and 13b complete of their respective edge thining 14a and 14b , are extending between them in the way that, as clearly relevable from the figure 5, when the same 13a and 13b are placed in closure, the respective edge thining 14a and 14b , are superposed reciprocally between them forming a complexive thickness that is equal or opportunely inferior of that af the relative corrugated cardboard used to obtain the respective parrallelepipedal box S.
Said second lateral elements C results instead divided in four parts by respective four "folding lines" L generating relative belts 15, 16, 17, 18. The first two belts 15 results laterally delimitated by two relative couples of folding lines L spaced between them how is the thickness that results between the two bigger faces of the resulting parallelepipedal box S, furthemore two of said folding lines L are corresponding to relative lesser sides of the rectangle forming said central element 11. Further couples of belts 16,17, 18 will have idoneous lenght and jointed to the relative first two belts 15 results to generate, by the wrapping on themseves, two correspondent tubolar elements with rectangular shape forming relatives elements of renforcement R of the respective lateral faces of the resulting parallelepipedal box S. How clearly relevable by figure 2 the parallelepipedal box S here above described will be particoularly idoneous to contain a relative panel P equally parallelepipedal which can be, as shown in said figure 2, a panel of a furniture.
At this point, ended the detailed executive descripition let alone conformative of the new parallelepipedal box S resulting modified by the present invention, appears obvious and evident the new and advantageous proceeding of closure that is possible to obtain with the same box S. The final closure of said new parallelepipedal box S will be, as clearly shown in figure 5, applying at least on one of the surfaces of said thickness edge 14a and 14b, precisely that which in the closure results opposite
between them, an idoneous glue E with an opportunely rapid effect and not of pulluting kind.
The application of sayd glue E will be obviously when the relative parts in which is divided the biggest face of closure formed respectively by the belts 13a and 13b, will find in an open position and then with the respective thickness edges 14a and 14b opportunely spaced between them and, at application done, said belts 13a and 13b will be closed in a very fast time in the way that the opposed surfaces of the relatives thickness edges 14a and 14b will go to impact reciprocally one against the other closing between them the glue E which also provocates the final fixing. The fast action glue that can be used could be constituted, for example, by a common and well known glue that can be melted by heating that, then needs the use of idoneous and note devices of heating and application. Could be provided the use of glue constituted by idoneous liquid substances and dense that can be applyed in several modes all known. Said substances (liquid or dense) doesn't ever permit an action of paste sufficiently fast, but they feel the effects of the accelerating might of said paste that can be produced by heating, produced by electrical resisteces, microwave or other forms of energy.
Consequently after the application of this kind of glue (liquid or dense) the zone of the opposed thinkess edges 14a and 14b placed in closure will be superposed, using idoneous known might, to the accelerating action produced by the kind of energy more idoneous at this kind of glue. At this point results evident how the improvement, that is the object ofthe present invention, permits for first to avoid all the difects and drawback that normally exists in the use of the adhesive tape done in plastic material and conteporaneously permits to obtain various and notable advantages of execution, of functionality and consequently economical advantages, Furthermore the present invention permits to obtain always a certai and sure closure of the parallelepipedal box S that forbid unauthorized opening that in this case will be easily findable and relevable.
At the end is to point the attention that, both in the description and in the drawings, it has been done reference only to a parallelepipedal box S which closure face results constituted by one of the bigger faces of the relative parallelepiped substantially divided longitudinally in two parts generating relative belts (13a and 13b) that extends themselves each one with relative width equal between them and ending in the respective free extremity with
correspondig thikness edges (14a and 14b) complemetarly between them both that when posed in a position of closure they result reciprocally superposed not let alon placed simmetrically long the longitudinal axis resulting centrally at the resulting reconstructed bigger face. Clearly the widths of the above mentioned parts (13aand 13b) resulting between them complementary can be also complementary different between them in the way that, in the relative position of closure the relative thickness edges (14a and 14b) don't result aymore placed long the longitudinal central axis but long relative longitudinal axis correspondently different. This and other variations can be brought at the present invention without going out from the subject-matter of how described and claimed with references to the enclosed drawings and then from the dominion of the present invention
