"HATCH PIN SET FOR HORIZONTAL SHELF ADJUSTMENT LOCKING SYSTEM, ON DISPLAY
This descriptive report refers to a patent application for a coupling assembly developed for the structuring of display displays, where at each end of the front edge of the shelf (pivotable or not) a pin is fixed. with split arrowhead. The pins, externally and horizontally facing from the ends of the shelf, are arranged to align with the respective female housings, in turn fixed vertically to the inner surface of the two side walls of the display body or to the display columns (in this case). displays with column-supported shelves).
At the point of assembly at the point of sale, with the initial closure of the sidewalls of the structure, simultaneously with the articulation or fitting of the shelves, after a simple pressure imposed by the user, made from one of the sidewalls of the structure (pushed horizontally). inward), the quick coupling between pin and housing is caused by initially locking the shelf on this side of the display. The user then performs the same procedure on the opposite side of the display, completing the shelf lockout.
In the case of shelves that can be fitted to displays with a structure consisting only of support columns, the same horizontal coupling procedure is performed, with the pins and female housings brought against them after light pressure from the columns by the user. Optionally the shelf can receive, during the manufacture of the display, an extender ruler also fixed along its front edge (used in cases where the display has to support heavier products). Such a ruler receives at its ends, slidably and slidably, its split arrow-tipped pin, both also turned externally and horizontally from the ends of the shelf. This ruler, preferably prefabricated in plastic material, in addition to the structure, allows the pins to be adjusted and locked in the shelf to the width of the display, while still maintaining the same coupling system horizontally when mounting on the point of sales.
Thus, by the proposed system between the pin and the housing (brought against each other from the pressure on the sidewalls of the cardboard structure or from the support columns), an extremely easy horizontal direction coupling is obtained for the structure of the shelves. on all floors of the display without any adjustments (such as raising the shelf to one side or the other, which usually causes undesirable unlocking between the initially coupled pin and female housing) for this important mounting task.
As is well known to professionals in the field, the display display manufacturing segment, used to receive and allow the visualization of the various goods produced by the industry to be sold in supermarkets, pharmacies, large magazines and others, is growing and increasingly requested. .
Some displays are mounted by opening their sidewalls and shelves hinged, which are locked along the floors on the sidewalls of their structure, while other displays have only support columns into which the shelves are fitted.
However, on the side edges of their shelves, they receive vertically arranged outer pins aligned with hollow body-shaped housings that are frontally bent into perfectly perpendicular edges, also arranged vertically on the inner surface of the sidewalls of the structure. or fixed to the support columns. When mounting the display at the point of sale, after opening its sidewalls and articulating the shelves, the pins must have their profile perfectly aligned with the opening of the corresponding housing rails so that, after axial imposition by the user, the coupling. In the case of speakers, the same procedure is done and the shelf pins must fit into the housings installed in the display support columns.
In any case, the pins must be coupled vertically axially as they descend against the housings to complete the mounting of the shelves and, consequently, of the display.
It is just that in this final stage of structuring a difficulty was detected, because when the shelf is lowered vertically, after the initial insertion of one of the pins of one of its sides, (for example on the left side), the opposite pin is usually not found. perfectly aligned with the rail of the corresponding housing. This is because it is really difficult for the user to align the fully rectilinear pin and rail profiles of the housing to the vertical descent of the first element. Therefore, it is necessary to slightly raise the shelf as a whole in an attempt to complete alignment and coupling of the pin to the opposite side housing (right side). However, this movement (lifting the shelf) can lead to the uncoupling of the pin (on the left side) that was initially locked, requiring a new procedure and thus delaying the assembly, especially in the case of several shelves subjected to this same type. alignment "adjustment" along the display floors.
Thus, for structuring the display at the point of sale there may be problems with the final locking of all your shelves, requiring a few precious minutes for this kind of adjustment between the vertical coupling of the pin and the housing, which despite Not to prevent its use is not an ideal situation, especially when mounting the point of sale.
Another issue concerns the structure of the shelf and the adjustment of the conventional (upright coupled) shelf pins. In this sense, the same author of the project in question pleaded in 2008, through the PI 0802314-0 deposited in Brazil, an extender ruler composed of two sliding and lockable laminar bodies, both equipped at their free ends with coupling pins. vertically to the female housing. During manufacture of the display, the ruler is adjusted in extent by sliding between their bodies and fixed by the upright coupling of their pins to the female housings fixed to the display frame to support the shelves. The deposited ruler has brought major improvements in structure and fit as it can be extended or retracted to adapt the width of the shelf to the width of the display to properly support it in the frame.
The lock assembly in question, which is the subject of this patent application, transfers the conventional vertical axial coupling between pin and female housing for locking the shelf and side wall or shelf and display column in general to a coupling system. in the horizontal axial direction. According to the proposed system, after the shelf articulation, when mounting the display it is easily locked with light pressure imposed from the side walls of the structure, brought in against it, and the same in case of displays with only support columns for the shelves.
By the proposed system, the "lifting" of said shelf on one side is avoided (after initial coupling on the opposite side - which conventionally causes disengagements), that is, lateral adjustments are now avoided for the final locking of the shelves when mounting the display. at the point of sale, facilitating the final assembly to receive and expose the consumer goods to be traded.
To this end, the shelf receives, during the manufacture of the display, along its front edge, bipartite end pins extending externally and horizontally to fit into female housings fixed to the inner surface of the side walls of the display frame. The female housings, in turn, have inward-facing bevels along the edges of their rail, forming specially designed ramps to allow the sliding of the angled peripheral stops of the split arrowhead, now arranged horizontally, extending externally to the from the ends of the shelf. With this arrangement a new technical effect is obtained, facilitating the moment of final locking of the shelf.
When mounting the display for use after the shelves have been hinged, the user simply has to press one of the side walls inwards horizontally so that the female housing can reach and be overtaken by the split arrow pin end, causing initial coupling on one side of the cardboard structure. Then, moving the opposite side wall of the cardboard structure, pressing it inwards in the horizontal direction, causes coupling on this other side without interference that could undo the initial locking of the opposite side.
With such procedures the split arrowheads, when forced, are deformed to ramp past the chamfered edges of their respective female housings, then open and lock on them by quick engagement, which is obtained. thus the final mounting of the display shelves, in actions that absolutely do not interfere with the coupling on either side of the cardboard structure, without the need for any lateral adjustments.
For displays with only column-supported shelves, the same horizontal coupling system is maintained between pins and female housings.
Optionally, along the front edge of the display shelf (during manufacture) can be attached a prefabricated extension rod made of plastic, with unprecedented construction to receive, from both sides, the arrow-shaped pins. which can be extended or retracted to fit the width of the display frame to align with their respective female housings. After adjustment, the pins receive bolts and locking nuts and are positioned for the same system in question, reason for this patent application, coupling horizontally to the female housings, for locking the shelves when the display is subsequently mounted at the sales.
Superficially explained, the invention is further detailed by the accompanying drawings. The following figures refer to the state of the art:
Figure 1 - Perspective view of a known display whose side edges of the shelf are provided with conventional vertical pins for locking to the vertical housings installed on the inner surface of the sidewalls of the cardboard structure. As noted, the shelves are being hinged and their pins will be coupled, after vertical downward movement, to the housings of the inner surface of the sidewalls. The vertical direction normally practiced for coupling between pin and housing is shown by dashed arrow, in some types of systems, in details AeB. Figure 2 - Perspective view of a display devoid of rear and side walls, manufactured therefore with shelves supported only by columns. The vertical direction of coupling between pin and housing installed in the column is shown in detail C;
Figure 3 - perspective view, showing the current difficulty in fitting the vertical pins in the housings. As shown in the example given in this figure, by the dashed arrows, when attempting to engage the left side (down arrows) of the display frame, the shelf should generally be slightly raised (up arrows). In this condition, with this vertical movement necessary for shelf adjustment, the pins on the opposite side or right side, which were initially coupled, eventually come loose from the housings (up and side arrows). For lower-floor shelves, the field of view is narrower, which makes operation even more difficult. The same difficulty is observed in the display made with column-supported shelves.
The figures below, 4 to 10, refer to the horizontal coupling, which is the reason for this patent application:
Figure 4 - perspective view showing a display with open walls and shelves not yet articulated. The shelves are provided at the ends of their front edge with split arrow-shaped pins, positioned horizontally for the horizontal coupling system with the female housings, in turn, fixed vertically to the surface of the side walls of the structure. ;
Figure 5 - An enlarged perspective view of a floor of the display structure showing the closure of the sidewalls with their female housings to which the split arrowhead pins will align to the horizontal coupling system . In detail D is shown, in enlarged perspective, the horizontal coupling direction between the split arrow-shaped tip pin and the chamfered edge of the female housing. The coupling will be made on each side wall of the display's cardboard structure, without the need for adjustments that can release, for example, one side of the already locked shelf;
Figure 6 - plan view showing, in sequence, through dashed arrows, the side walls of the display being pressed inwards for the horizontal coupling. In this condition the pin fixed to the end of the front edge of the shelf will overtake, by the angular peripheral stops of its split arrow tip, the chamfers of the female housing rail edges. In detail E, sidewalls of the display frame are shown being pressed inward in a horizontal axial direction to cause coupling between the pin and its respective female housing. In this condition, as detail F shows, the angled peripheral stops of the split arrowhead tip of the pin are deformed for overrun in ramp system tangent to the chamfered edges of the housing rail. As shown in Detail G, the angled peripheral stops upon return engage the split arrow-shaped tip of the pin behind the chamfered edges of the female housing, causing one side of the display frame to lock. Detail H shows the same procedure being performed independently on the opposite side of the display frame and Detail I the final coupling on that same side, completing the final shelf locking. As shown by the sequence shown, the shelf locking is performed without interference that may cause the previously locked shelf side to be decoupled, avoiding lateral adjustments to either side of the display frame when assembled;
Figure 7 - Perspective view of a display floor showing a shelf being locked on either side of the cardboard structure. As noted by the dashed arrow, the sidewall is pressed inwardly so that the angled peripheral stops of the split arrow-shaped tip of the pin are overcome by the chamfers of the female housing rail. The enlarged detail J shows the locking of the shelf with the return of the angled peripheral stops that engage within the housing rail. The enlarged detail K shows the pin coupled along the side edges of the shelf in a constructive option, while maintaining the same horizontal locking system;
Figure 8 - perspective view showing the constructivity of the extension ruler, which will be fixed along the front edge of the shelf (when manufacturing the display). Through the ruler an adjustment is made to increase or decrease the distance between the split arrow-shaped pins, making them suitable for locking the shelf according to the width of the display frame during manufacture. As can be seen, the extension ruler has a hole and receives, at both ends, the socket of the pins, equally endowed with hole. The pins run through the extension ruler and, after finding their position, according to the length of the shelf, through their aligned holes is made locking, with the insertion of screws and nuts;

After finding the desired position, depending on the width of the display structure, the pin will be locked by screw and nut inserted in their holes aligned with the holes of the extension ruler;
Figure 10 - perspective view of a display with the shelves provided along its front edges with the extension ruler, which fixes, at its extremities, its split arrow-shaped pin, all already adjusted and locked (during the fabrication of the display) for coupling to the chamfered female housings, fixed to the surface of the side walls of the structure. On the side is shown the enlargement of the closure of the sidewalls with their female housings, to which will fit the split arrow-shaped pins, previously adjusted in the distance from the extension rule, to the horizontal locking system. . In detail L is shown, in enlarged perspective, the horizontal direction of coupling between the split arrowhead pin and the chamfered edge of the female housing, maintaining the proposed system. In accordance with the accompanying drawings, the "PIN SET
HOOK FOR HORIZONTAL SHELF ADJUSTMENT LOCKING SYSTEM ON DISPLAY DISPLAY ", object of this patent application, consists of a display (1) with manual or automatic opening display, consisting of rear wall (2) ) through which the sidewalls 3 of the frame are hinged.The display (1) can be of the type devoid of rear and sidewalls, ie with their shelves structured only by columns (C). Figure 1, 2 and 3 show prior art displays (1) receiving shelves (5) hinged from their rear walls or snapped along the supporting columns (C).
According to the constructivity and system proposed for the set, reason for this patent application, to be shown by the following figures, during the manufacture of the display (1), on the front edge (4) of the shelves (5), as illustrated in figure 4, A pair of pins (6) are fixed from each end, both of which are positioned externally and horizontally, each composed of a split arrowhead (7) with two circumferential angled stops (8). by central tear (9), as illustrated in particular by detail D of FIG. 5. In said detail D it is also shown that the pins (6)
extended from the ends of the shelf, corresponding to the coupling are respective female housings (10) installed on the inner surface of the side walls (3) of the display (1) and which, in turn, are provided with beveled inward edges (11). ), in ramp form, along its rail (12).
According to the system obtained by the constructivity of the set, at the moment of the assembly of the display (1) at the point of sale, by the user, its side walls (3) are initially closed against each other simultaneously at the beginning of the articulation of the shelves (5). In this condition, as illustrated by detail D of figure 5 and the sequence of figure 6, it is sufficient for the user to press one of the side walls (3) of the display (1) in horizontally inward (detail E), so that the peripheral angular stops (8) engage the chamfered edges (11) of the rail (12) of the female housing (10). Thus, by sliding horizontally for overtaking, the peripheral angular stops (8) of the split arrowhead (7) of the pin (6) deform from the slot (9), converging against each other towards the overrun (detail F) and then open, returning to lock behind the chamfered edges (11) inside the rail (12) of the female housing (10) (detail G), locking the shelf (5) on the wall (3) on one side of the display frame (1).
The same procedure is done on the opposite side of the display frame (1), (detail H), with the side wall (3) being pushed inward to also cause coupling between pin (6) and female housing (10) (details HeIe also detail J of figure 7), thus completing the locking of the shelf (5). Detail K of Fig. 7 shows that the pin (6) can be installed along the side edges of the shelf (5), therefore its body is fixed at another positioning angle, in a constructive option. Also in this condition, the sidewall is pushed inward to also cause coupling between pin (6) and female housing (10), thereby maintaining the same system.
As can be seen, the horizontal direction of the coupling, carried out independently on both sides in the side walls (3) of the display frame (1), has as its main objective not to interfere on both sides when mounting the display. This avoids side adjustments such as lifting the shelf (5) (which may cause slippage), thus simplifying and speeding up the mounting of the display (1) at the point of sale.
In the case of displays (1) with column-supported shelves (C), the system is maintained, ie the columns (C) receive the female housings (10) and the shelves (5) receive the pins (6). In this case, the columns (C) are brought against each other so that the pins (6) of the shelf (5) are equally coupled horizontally in the female housings (10), keeping the shelf locking system (5) in the same way. horizontal direction in question, reason for that patent
Optionally, as shown in figure 8, the display (1) may receive an extension ruler (13) prefabricated in hollow plastic, hollow through holes (14) and open at its ends (15), through which it receives the sliding insert. pins (6), in this case provided with holes cast by holes (6a). Through their bodies the pins (6) can be extended or retracted to fit the width of the display as shown in figure 9 and, after finding the position, by their aligned holes (6a) and (14) receive bolts and locking nuts (16). Thus, during manufacture of the display (1) the pins (6) can be pre-adjusted in their positioning, with the split arrow-shaped tips (7) already naturally aligned with the beveled inward edges (11) of the rails (12) corresponding female housings (10) along both side walls (3) of the display (1).
The extender ruler (13), in addition to allowing the shelf to be structured (in case the display receives heavier products to be exposed), and allowing the pins to be pre-adjusted (6) according to the shelf width (5), maintains the same. horizontal coupling system to the female housings 10, which is the reason for this patent application, as shown in the enlarged detail L of Figure 10.
