Description

Container for packaging parts with at least one opening

The present invention relates to the field of industrial equipment, in particular containers or packaging for packaging and transport in groups or batches of trim or functional parts, in particular of large size or surface extension, in particular sheet metal bodywork parts, and susceptible to deformation during transport or handling.

In this context, the subject of the invention is a container for the packaging of parts provided with at least one opening, and capable of receiving a plurality of such parts.

The invention relates in particular to the type of containers in which the parts are stored suspended from brackets and being stacked in a horizontal direction (parallel to the bottom of the container), one behind the other in an aligned manner.

In this context, the invention applies more specifically to a container for packaging parts provided with at least one opening, cutout or similar opening and intended to be arranged side by side in said container while being substantially aligned along a stacking direction.

Such a container essentially comprises a base and a supporting superstructure extending above the latter and at least partially delimiting a volume for receiving parts (above the base). Said parts are received in said container by being at least held by suspension or hooking on at least two elongated brackets extending substantially along the direction and each secured at one end to said superstructure, thus extending cantilever from said superstructure. These brackets each comprise a plurality of support sites distributed over their length, aligned along the stacking direction and each intended to cooperate with a bearing zone of an opening or cutout of a part when the latter is placed in the container being threaded onto these brackets by the opening(s) or cutout(s), with a view to maintaining it by hanging or hanging.

Currently, these brackets provide support sites (in individual and discrete form or in the form of a continuous surface) fixed, and with quasi-point contact surfaces, which can generate mechanical stresses locally and in the structure of the part in general. , or even cause twists and/or deformations in the latter. It is therefore necessary to manufacture and mount these stems and the superstructure with a very small tolerance, which is tedious, difficult and expensive. And even if the jib cranes are made and installed very precisely, the final positioning of the part in the suspended state cannot be guaranteed, nor therefore the absence of the negative effects mentioned above.

The main purpose of the present invention is to improve a container of the aforementioned type in order to overcome these drawbacks.

To this end, the subject of the invention is a container for the packaging of parts provided with at least one (e) opening, cutout or similar opening and intended to be arranged side by side in said container being substantially aligned in a direction stacking, this container essentially comprising a base and a supporting superstructure extending above the latter and at least partially delimiting a volume for receiving the parts, and the said parts being received in the said container while being held at least by suspension or hooking onto at least two elongated brackets extending substantially along the direction and each secured at one end to the said superstructure, cantilevered, these brackets each comprising a plurality of support sites distributed along their length, aligned along the direction of stacking and each intended to cooperate with a support zone of an opening or cutout of a part when the latter is placed e n place in the container, by being threaded onto these brackets by the opening(s) or cutout(s) with a view to keeping it suspended,
this container being characterized in that the support sites of at least one stem are mounted on or form part of an elongated constituent component of the stem considered capable of pivoting, freely or against a return torque or prestressed, around an axis which is substantially parallel to the stacking direction and in that the contact zones between support sites and bearing zones are preferably in the form of lines or bands.

The invention will be better understood, thanks to the description below, which relates to preferred embodiments, given by way of non-limiting examples, and explained with reference to the appended diagrammatic drawings, in which:

is a partial perspective view of a container according to the invention in accordance with a first embodiment (a single bracket is provided with pivoting support sites);

And

are perspective (3A) and front elevation views along the stacking direction (3B) of a container according to a second embodiment of the invention (the two brackets are provided with pivoting support sites), in which a piece in the form of a car door was put in place;

And

are views on another scale respectively, in elevation, of detail A of the and, in perspective, detail B of the ;

is a view to another scale of the brackets shown in Figures 4A and 4B;

is a detail view at another scale showing the stem of the in the exploded state, and,

is a view similar to that of the illustrating a jib crane fitted with a variant embodiment of pivoting support sites (discrete sites, with room dividers).

Figures 1 to 3 show a container (1) for packaging parts (2) provided with at least one opening, cut-out or similar opening (2', 2'') and intended to be arranged side by side in said container being substantially aligned along a stacking direction (DE).

This container (1) essentially comprises a base (3) and a carrier superstructure (3') extending above the latter and at least partially delimiting a volume (V) for receiving parts (2), and said parts (2) being received in said container (1) by being at least held by suspension or hooking on at least two elongated brackets (4, 4') extending substantially in the direction (DE) and each secured at one end (5 ) with said superstructure (3'), cantilevered, these brackets (4, 4') each comprising a plurality of support sites (6) distributed over their length, aligned in the stacking direction (DE) and each intended to cooperate with a support zone (7, 7') of an opening or cutout (2', 2'') of a part (2) when the latter is placed in the container (1) , being threaded onto these brackets (4, 4') by the opening(s) or cutout(s) (2', 2'') with a view to keeping it suspended.

According to the invention, the support sites (6) of at least one stem (4, 4') are mounted on or form part of an elongated constituent component (8) of the stem in question (4, 4') capable to pivot, freely or against a restoring or prestressing torque, around an axis (AP) which is substantially parallel to the stacking direction (DE) and in that the contact zones between sites support (6) and support zones (7, 7') are preferably in the form of lines or bands.

Thus, by providing mobile support sites (6), by pivoting of the stem component (4, 4') to which they are attached, the latter have a certain degree of freedom and can adapt, on the one hand, to the direction in which the support zones (7, 7') come into engagement under the weight of the parts (2) and, on the other hand, to the local configuration of these zones. Furthermore, by providing non-point contact areas, the pressure stresses are distributed. These provisions of the invention make it possible to greatly limit, or even completely eliminate, the excessive mechanical stresses (that is to say not directly induced by the locally supported load) at the level of the support zone coming to rest on the stem. concerned. The tensions in the part (2) are also reduced and the distribution of the load between the two brackets is better balanced, also inducing a more stable and better stabilized storage of the parts (2). Of course, the support sites and the support zones intended to come into mutual contact have as far as possible plane and rectilinear shapes, or mutually complementary (if not plane or not rectilinear), in order to provide as many contact zones as possible. at least linear or in the form of bands.

As shown in Figures 1 to 6, and in accordance with a first variant embodiment, each support site (6) consists of a line or a transverse strip of a continuous support surface (6'), preferably planar and having properties anti-slip and/or elastic deformation, forming part of or attached to one face (8') of said constituent component (8), engaging the parts (2) in their suspended state.

As shown in , and in accordance with a second variant embodiment, each support site (6) consists of a notch, a notch or a similar depression forming part of or attached to a face (8'), preferably planar, of the said constituent component (8), engaging the parts (2) in their suspended state.

In accordance with an embodiment shown in Figures 3, provision may be made for each of the two brackets (4, 4') to comprise a pivoting component (8).

According to another embodiment emerging from Figures 1 and 2, it can be provided that only one (4) of the two brackets (4, 4 ') comprises a constituent component (8) pivoting, the support sites (6) of the 'another bracket (4') being mounted fixed on the latter.

According to a practical construction illustrated in Figures 4 to 6 in particular, the or each pivoting constituent component (8) consists of an elongated profiled element, such as a hollow tube or an angle iron, extending substantially over the entire length of the stem. (4, 4') concerned, having a face (8') for engagement of the support zones (7, 7') of the parts (2), provided with or providing support sites (6) and pivotally mounted at its two opposite ends in respective bearings (9, 9'), one of which is secured to the supporting superstructure (3') or to the end (5) of the jib (4, 4') connected to this superstructure and the other of which is secured to the free end (5') of this stem (4, 4'). A return spring urging the component (8) around the pivot axis towards a default abutment position is advantageously provided (not shown). This pivot axis (AP) may for example consist of a single rod passing through the two bearings and extending between them.

In order to further distribute the local mechanical stresses (at the level of the support zones) induced by the weight of the suspended part (2) and simultaneously to better wedge said part in position, provision may be made for the, one or each of the two brackets (4, 4') which comprises a pivoting constituent component (8) also has at least one fixed support surface (10) and/or at least one fixed contact surface (10'), configured to cooperate with the support sites (6) with a view to wedging the parts (2) in position in planes perpendicular to the stacking direction (DE), this or these fixed surface(s) being provided by one or more corresponding elongated component(s) or constituent part(s) (11, 11') (see FIGS. 1 to 6).

As emerges more particularly from FIGS. 4 to 7, said at least one fixed support surface (10) and/or said at least one fixed contact surface (10') has (have) a profiled configuration along the stacking direction. (OF) and rounded or curved in cross-section to that direction.

In accordance with a beneficial characteristic of the invention, emerging in particular from FIGS. 4, the invention may provide that for at least one bracket (4, 4'), the pivoting constituent component (8) and at least one of a fixed support surface (10) and a fixed contact surface (10') are configured and arranged on the console (4, 4') considered in such a way that they all come into engagement with support zones (7, 7') respectively and grouped together locally in a region of the opening (2', 2'') of a given part (2) and together provide support by suspension and at least partially wedged in a plane perpendicular to the direction of stack (DE) of this piece (2).

This region of a through opening of the part (2) can for example be a rounded corner of this opening.

Advantageously, the alignment of support sites (6) is slightly inclined downwards towards the free end of the bracket (4, 4') considered.

Preferably, each bracket (4, 4') is removably fixed to the supporting superstructure (3'), the latter forming at least one face of the container (1), perpendicular to the stacking direction (DE) and opposite to the exposed face for inserting the coins (2).

In connection with a particularly interesting application of the invention, and as is apparent from FIGS. 2 to 4, the two brackets (4 and 4') are configured and arranged on the carrying superstructure (3') with a view to receiving maintenance by hooking with suspension, and preferably with wedging in a plane perpendicular to the stacking direction (DE), of parts (2) of motor vehicle bodywork, in particular doors, the carrier superstructure (3') advantageously having a plurality bracket attachment sites (4, 4'). These parts (2) are hung on the brackets in the upper part, so that their center of gravity is located much lower than said brackets and the latter are spread apart as much as possible to stabilize the carrying of the part.

As shown in the figures, each stem (4, 4') has a base body (12) in the shape of a full square. Instead of a solid plate, the bracket could also be hollow or be limited to an L-shaped part. The container (1) can also comprise additional means for lateral wedging of the parts (2) in the lower part, for example under the form of a ramp or a bar (13). Means for spacing or wedging the parts (2) in the stacking direction (DE), for example fingers or cushions (14) mounted on arms (14') which can be retracted laterally by pivoting, can also be provided. .

These additional means are advantageously mounted, for a container of parallelepiped shape, on the two side walls of the superstructure (3') extending in planes parallel to the stacking direction (DE) and connected by the wall bearing the brackets (4, 4'), the fourth face being open and unobstructed. These means (14, 14') can be adjustable in position according to the stacking direction (DE) and a couple of opposite means serve as end stops, preventing the fall of the last part suspended on the brackets. The superstructure (3') can advantageously have a mechanically welded tubular construction with uprights at the level of the angular corners of the rectangular base (3), allowing the vertical stacking of the containers, the jib cranes being able to be mounted on two specific uprights of the superstructure ( 3').

Of course, the invention is not limited to the embodiments described and shown in the appended drawings. Modifications remain possible, in particular from the point of view of the constitution of the various elements or by substitution of technical equivalents, without thereby departing from the scope of protection of the invention.
