Description

Retention piece for a container with handle.

The invention relates to a "buttonhole of plate-shaped retention "and to a procedure of manufacturing.

Known containers have on their wall outside of the body "eyelets" placed on the outside, which they have a bell configuration that is projected greatly out. The bells that project in cantilever in great measured outward receive an outside area in the form of an arc or in V shape of a handle, to be able to grab the container, see this with respect to figures 1 and 2 of document DE-U 16 55 273 (Tinnerman), and all the figures in the document US-A 2,176,711 (Gorman), and Figure 3 of the document EP-A- 516 605.

The problem of the invention lies in reducing the height of the retention eyelets, approximate the body of the container in the shape of a cylinder or oval shape and in no hinder manufacturing the container with a piece of new retention for the handle.

A flat, plate-shaped retention piece, which has a diameter greater than double, especially greater than Three times its height, it offers the solution of the problem. The piece of plate-shaped retention has approximately one in the center hole, which has an edge that points inwards and that extends on the periphery, which is elastically configured flexible (claim 1). If the end of the wing is pressed transversely in the hole, then the edge (the edge inside) yields elastically and can be elastically fitted in again behind a thickening of the handle end introduced in the retention plate and can be locked.

A container configured with these pieces of retention solves the problem mentioned in the same way previously.

The end of the handle (clamp) extends from according to the invention essentially perpendicular to the axis of the body. At its innermost end it is thickened especially in Bulb shape, to fit and disengage. Facing the clamping tabs configured in V-shape and pre-folded (folded out) according to DE-U 16 55 273 or DE-A- 23 51 796 (Rapid), the elastic configuration of the inner edge bent or folded out of the hole according to the invention offers an elasticity, which is available in both addresses.

The development of the grip handle end on the retention piece on the side wall of the container is occupied that no operating force component be extended in the Lace direction and disengagement. On the one hand, in the state of technique, in the extreme V-shaped area there is always a rotation position of the handle, in which the handle can slide out of the bell piece, such as when it is deposited the container and the handle is released, which is still in its position of turn pointing up. In the latter case, the handle is would slide out of the retention piece and should be inserted into first again, when the container must be lifted by the handle.

On the other hand, the invention is always concerned that in the case of a lace and unlock aligned approximately horizontal end of the handle, do not extend in this direction no component of the lifting force, which is transmitted on the bowl The handle cannot slide in position embedded through operational movement outside the piece of flat retention

The thickness of the thickening and the diameter of the hole are adapted in this case to each other in such a way that the elasticity of the inner edge or the inner edge area is precisely enough to let the final thickening of the handle. Then the handle is locked, but in the same way it can pull back transversely out of the wall of cover of the retention piece.

Elasticity is achieved through at least two slots that are arranged in the cover wall of the retention piece and pointing radially outward. Segments are formed between the grooves, which are elastically flexible and that allow the end of the handle to fit with the thickening, although the diameter of the hole in the piece of retention in the unloaded state is less than the diameter of the thickening.

Facing the hole with elastic inner edge in the retention piece, in the body of the container is arranged a first cavity, which receives the end of the handle of grip, that is, its thickening, at least partially. This way, a very flat structure of the eyelet of retention "; it is fixed in a simple and fast way in the container and the handle assembly can be simplified and secured grab Unlike the state of the art, according to the invention, the end area of the grip handle is embedded essentially transverse in the "spherical eyelet hole", under assignment of the "buttonhole cover" (roof wall) in the marginal area of the accommodation hole. To that end, a piece end of the grip handle extends practically horizontal, to difference of a V-shaped arc or buckling in the state of the technique, which cannot be received either partially in a cavity under the bell-shaped retention piece; to to this end, its turning radius during the activation of the handle towards the use position turned up is too large.

The application of the retention piece is achieved through the weld joint of the frontal zone lower, proper only of the lower front edge. The piece of retention carries projections or projections distributed in the periphery, which are placed in a mechanically fixed manner during welding as a butt welding under pressure in the body of the container.

The peripheral wall has been completely omitted, being welded together from the cover wall about protrusions specially folded down directly on the container, to cover the cavity provided there and to receive the thickening practically of everything in the cavity end inserted and embedded transversely. The "eyelet in shape of bell "has thus become a plaque.

The retention plate set only to from a cover wall, the so-called retention piece in plate shape, will be fixed on pins (protrusions suitable for welding) in the metal container at the edge higher. The projections are arranged either on the edge side on the cover plate or in an intermediate zone annularly in the inside area of the roof wall. The intermediate zone of the roof wall may be ring-shaped, such so that radially within this zone, that is, towards the hole, and radially out of this area, that is, towards the edge  outside the roof wall, two other zones are planned ring-shaped In the intermediate zone, the pins can be prepare advantageously through incisions approximately T-shaped and then can be folded towards a direction of the roof wall like pins triangular If the pins are not arranged on the edge outside, but deeper inside the roof wall, its stability and become more resistant to torsion.

The lower ends of the bent pins out, specially configured in pairs, end in tip, to support a weld joint as a weld butt in a metal container.

The peripheral distribution of the pins folded out can be adjusted below according to the retention forces that must be absorbed. Most of the sometimes three to six pairs of sideburns are sufficient, which placed, in the assembled state, in the container around the bucket-shaped cavity provided there for housing the extreme area of the handle, which is inserted perpendicular to the axis of the container and are fixed there by welding.

The pin pairs configuration prepared through the T-shaped section with two triangles separate allows simple manufacturing; after the Stamping of T-shaped sections can be folded towards outside the two triangular flaps resulting in the lines of bending from the plane of the roof wall, whose lines of bending are formed between the ends of the sections in the form of T.

In outgoing configuration in pairs triangle-shaped result oriented triangles perpendicularly, that point with one of its corners as a point down, to facilitate welding bonding, but also they have an orientation with the plane formed by the triangle, which form with a radial vector radius, which starts from the center of the hole, an angle greater than zero.

In the triangular configuration by couples turn out, facing the roof wall, triangles inclined, which points with its common outer corner as a tip down, to facilitate weld bonding, but also to give the buckling lines formed by the triangles a orientation, which forms with a radial vector radius, which starts from the center, an angle less than zero. The triangles bent towards outside in pairs in this case they have an instep line or line of edge that projects downwards, that forms in front of the radius vector an angle greater than zero and against the plane of the wall of cover extends from it inclined. The singing outer front (the "edge") of the retaining part in the outer end of the edge line forms the junction point by welding, because it is especially inclined for joining by welding. It is understood that in this case the annular zone begins at the outer edge of the retention piece and extends radially inward, to terminal clearly in front of the hole edge line, elastically configured in segments, for housing the end of the handle.

The elastically configured hole, especially with the segments that yield elastically and that are configured by means of cuts, it has a periphery essentially circular, adapted to the end of the handle that extends oriented perpendicular to the axis of the container, whose end of the handle is thickened in the form of a bulb. This end in Bulb shape is received by a cavity. This cavity is covered by the plate-shaped retainer, for which purpose the triangular shaped projections described are welded together in the wall of the container associated with the cavity in the form of bucket.

The plate-shaped retainer can being in this case in a cavity that receives it practically, having this cavity a smaller depth than the cavity provided for the end of the bulb-shaped handle. A piece of plate-shaped retention arranged in this manner does not apply already, in general, in radial direction.

The cavity that receives the retention piece respective can be extended as circumferential groove, of so that only in two places of this groove ring is carries out the arrangement of the retention pieces in the form of license plate. But two opposite cavities can also be provided and corresponding in their configuration to the outer wall of the plate-shaped retention piece, which receive two pieces retention plate. The respective diameter of these cavities is most often greater in one measure insignificant than the outer diameter of the retaining piece in plate shape: the same measure can be applied for the dimensioning of the circumferential continuous groove.

Such an arrangement provides a flat coverage of the cavity that receives the end of the handle in the vessel wall

The end of the bulb-shaped handle may be configured in the trapezoid shaped cross section, in cone trunk shape or round to oval, must have a front section a smaller diameter than a section that is further back, to facilitate wall insertion elastic inside of the plate-shaped retention piece.

The following explains and completes the invention with the help of examples, whose figures 1 and 2 are not comprised by the claimed invention.

Figure 6 illustrates a fragment of Figure 1 in the area of the plate-shaped retention piece, which is fixed at welding junction points 38 in a cavity 11, 12 of the wall of the container that extends at least partially in the circumferential direction

Figures 7a, 7b and 7c show different embodiments of the end of the cord 15a of the handle G.

Figure 8 illustrates a projection view on the placement of the handle, shown in figure 6 in the section lateral, on the wall of the container 30.

Figures 9, 9a, 9b and 9c illustrate several projection views 37 arranged in the retaining part H in plate shape, for the formation of welding junction points 38 according to figure 6.

Figure 1 illustrates container B as a cube or cylindrical sheet metal tray, for example for paint reception A cover D is shown in the raised state by above the upper edge of the container B. The lid is configured as a pressure insertion cover, and a cover ring forms the area of the upper edge R of the container and the edge inside, in which the cover D with sealing effect fits a piece of cylindrical wall. A handle G is represented as a handle in U shape largely open, which is arranged on two sides exteriors of a wall of the container 30, which forms the body of the container B, in retaining parts H that are explained with more detail at a clear distance from the upper edge of the container. The body B has a central axis 101, which is perpendicular in the supposed case, so that a horizontal axis 100 extends through the center of the retaining piece H. Yes nothing else is explained, the container is described in the state placed vertically, to establish the concepts "horizontal" and "vertical".

Figure 1 shows in the left half a side view and in the right half a section. The handle G hangs release down; it has a clamp-shaped section 15b and at each of its ends it has an extreme zone 15c, which extends approximately horizontal along axis 100, which is provided with a thickening 15a at the end. This thickening is depicted in figure 1 so that it fits in the piece of bell-shaped retention. Under thickening or below of the bell is arranged on the wall of the container 30 a approximately circular round cavity 10. that can be recognized in the section. The hole 22, through which the end is passed 15a in the form of the end piece cord or the area extreme 15c straight aligned, has a diameter such that it is smaller than the thickening 15a in the form of a cord, but it is at least as large as the diameter of the supposed end zone 15c round of the handle G. Possible configurations of cord-shaped thickening 15a they are represented in figures 7a, 7b and 7c. A thickening in shape of bulb in the configuration of a 15a rounded bead depicted in figure 7c. The round shape can be also configured in the form of a lens that extends more thick transversely than in the longitudinal direction, in order to get a clearer 16 overhang in the transition to the linear section of the handle 15c. The front end may be beveled, as shown in figures 7b and 7a. They are set cross section shapes in the form of trapezoids or logs of cone, the cone trunk being configured in the front area in the trapezoid shaped cross section and in the rear in the form of a cylinder. Here the protrusions 16 are represented more Clear to make removal of the handle out of the hole 2 difficult. The front ends are reduced more strongly to facilitate insertion Chamfers should be aligned with such that the inclined surfaces affect the line unloaded marginal hole 22a.

Figure 2 illustrates in three representations, a perspective representation shown first, a side view and a projection view, the retention piece H in bell shape of figure 1.

The perspective representation of Figure 2 illustrates hole 22 and direction 100, in which the part Extreme 15a, 15a ', 15a' 'in the form of a cord is inserted into the hole 22. The bell-shaped end piece H has a shape approximately cylindrical with a cylindrical wall 20 not high but which can be designated rather as flat and with a wall of cover 21, which is represented here in a circular round shape. He cover wall diameter 21 is at least of the same magnitude that the diameter of the cavity 10 in the wall of the container 30, of so that the annular wall 20 can be supported together and outside the cavity 10 in the case of wall fixing 30.

For fixing the retention piece in bell shape, which has a shape according to figure 2 cylindrical cup-shaped, with a flat cover 21, are planned projections 27, which are arranged in the front edge of the cylindrical wall 20 that is directed towards the container. A  regular cavity provides a uniform retention force, which is obtained during welding by way of welding to pressure stop under the cavity cover 10 of the container.

After the arrangement of the piece of bell-shaped retention H on the wall of the container 30, is covers the cavity 10, is surrounded by the annular wall 20, and a hole 22, which is located directly on the cavity 10.

In hole 22 the pressure is introduced linear end 15c of the handle with the cord 15a.

During insertion, an inner ridge 22a, which delimits hole 22, yields elastically, which is achieved by through the cuts or grooves 23a, 23b, 23c, 23d, shown at from hole 22 in the projection view on the wall of cover 21 at the bottom of figure 2. In the example represented, these slots extend directly radial and Four slots are provided. The slots deal with the configuration of segments or flaps that, in the case of loading with pressure from the cord 15a of the handle G on areas together and outside the hole 22 yield elastically and allow cord insertion 15a behind the cover wall 21. After insertion, at minus a part of the cord 15a, 15a ', 15a' 'remains in the cavity 10, because the height h of the retention piece H in the form of hood is selected greatly reduced. In effect, it is essentially less than half the diameter 2r = d1, which is represented in the side view. In this way, the bell H is flat, but you can insert, however, the handle with its end zone 15c and its cord, because cavity 10 receives a part of the cord. Nonetheless, the container remains tightly closed, without it interrupt wall 30 either in the retention zone.

The inner edge 22a which yields elastically is you can select more less elastic, according to the number of incisions 23a, 23c, ... radially directed, designated as abbreviated continuation with 23, which are made in the cover 21 from the inner edge 22a of the hole 22. It recommends aligning slots 23 so that they point directly between respective protrusions 27 at the lower edge of wall 20. But they can also be aligned as depicted in the Figure 2. If they line up in the center over the intermediate spaces between projections 27 (as welding legs), then it precisely align the areas of the segments, which are formed between the grooves, on a fixing point joined by welding in each case. In this way the forces of bending, without deformation of the wall 20.

If the cord is configured at the end of the handle with a larger diameter, then the forces for the fitting and disengagement of the linear end zone 15c and, therefore, the Handle G arrangement is more stable. The cord should not selected in diameter smaller than hole 22 in the non-state loaded (that is, without force acting in the direction of the axis 100), for the fitting and disengagement to take place.

The cavity 10 is selected in its depth greater than the flat height "h" of the piece of retention H. In this way it can be ensured that the device retention according to the example of the invention is projected less cantilever, that is, that it be placed only flat on the vessel wall 30, weld there and an essential part of the cord at the end of the handle is received by the cavity 10 aligned inward

The protrusions 27 in the lower edge of the annular wall 20, projecting laterally or pointing towards the wall of the container 30, can be arranged as one or two couples, which is mostly stable enough from the mechanical point of view.

Figure 3 shows a retention piece H in plate shape, without annular wall 20 only with a wall of deck 21 and with protrusions 27 arranged directly there, for the container wall placement. The cavity 10 is selected in this case deeper than in the case of the piece of retention according to figure 2 and receives the full thickness of the thickening of the end of the handle, covered only by the wall of cover 21 provided with hole 22, to receive a minimal lateral projection. The protrusions may be bent out clearly in a simple way, especially between 30º and 90º, from the plane of the cover wall 21, in order to generate contact points during welding a reduced surface measure.

Figure 4 illustrates in two representations a H-shaped retention piece, without annular wall 20 only with a cover wall 21 and with protrusions 27a, 27b arranged directly on it for application on the wall of the container 30. Also here the cavity 10 in the container is selected deeper than in the example in figure 2, to receive virtually the entire thickness of the thickening at the end of the handle, covered only by the cover wall 21 provided with the hole 22, in order to achieve a minimum projection in cantilever

The protrusions can be folded out clearly in a simple way, especially between 30º and 90º, from the plane of the cover wall 21, in order to generate during welding connection some contact points of a reduced surface measure.

In Figure 4, protrusions 27a, 27b set below as "welding legs" are folded in an area out of the cover wall 21, which does not it is arranged on the outer edge, but is oriented more towards the inner zone. This zone is set as zone marginal 21m, which is included by an outer ring 21a and by a inner ring 21b. All three annular zones form the wall of cover 21, which has the hole 22 inside described above with the inner edge that yields elastically

In the intermediate zone 21m are planned 28 places in the form of triangles, which are arranged distributed  on the periphery, which point with its pointed end towards the center of the cover wall 21 as a retaining piece in plate shape. Uniform distances are represented between 28 individual places, separated in each case 60º approximately. From these places 28, the legs of welding 27a, 27b in triangle shape in pairs, respectively, with a pointed end that is directed towards below, as can be seen in figure 5 in the view in the BW address of Figure 4. The zones 28 that are deduced in this case from figure 4, in each case they have a surface double, facing each of the pairs of welding legs 27a, 27b bent in triangle form from this surface, as shown in figure 5, the separation of the surface along an intersected line of intersection 30 radially An intersection line 30t oriented in the periphery, which is aligned perpendicular to the line of radially oriented intersection 30r, allows the extraction of two triangle-shaped pieces down, as represented by schematic form in figure 5. After the introduction of the T-shaped intersection line 30r, 30t, are formed as a line of joining the three ends of the T section two lines of flexion 29a, 29b, which serve for leg flexion 27a, 27b outward, the orientation of the shaped legs not being radial of triangle, but are oriented at an angled angle with with respect to a radial vector radius.

The configuration with the leg ring of welding, which is inside the roof wall, It is mechanically stable and prevents deformation of the plate deck 21, stabilization zones being provided in the form of ring both inside and outside. The retention plates do not they are deformed neither in the case of mechanical solicitation, nor in the case welding, or in the case of pressure application for the butt welding on the vessel wall.

In the state connected by welding, the welding pins 27a, 27b are welded around from cavity 10, which follows from figure 1, on the wall of the container 30, projecting the outer ring 21a freely Cantilever

Figures 9, 9a, 9b and 9c illustrate representations of a plate-shaped retainer without annular wall 20 only with a cover wall 21 and with projections 37 which are arranged directly therein, for the application on the wall of the container 30. Here the cavity 10 in the deepest container than in the example of the Figure 2, to receive practically the entire thickness of the thickening  at the end of the handle, covered only by the cover wall 21 provided with hole 22, to keep projection to a minimum cantilever side.

The projections 37 may be bent from one light and clear way, especially between 30º and 90º from deck wall plane 21, in order to generate during the welding connection surface contact points reduced, as shown in figure 6 in a state bound by welding on a wall of the container 30 represented in a fragment.

The projections 37 are configured in the form of triangle with two triangular sections, which have a line of instep or edge 37r, forming the bent triangles towards out in pairs in its bent out position with a radius radial vector (in the plane of the roof wall) an angle α> "zero", as follows from the view side of figure 9a. At the outer end they are formed welding junction points 38, which form the end of the line of edge 37r. The edge line extends at an angle? facing the plane of the cover wall 21. The two triangles between the edge line and two other buckling lines 37b, 37a radially divergent essentially in the plane of the wall of roof are inclined with respect to the roof wall, as it follows from figure 9c in the projection view and in the fragment A representation shown in perspective in the Figures 9, 9b illustrates the orientation of the projections 37 that are wedge-shaped projection down as well as its junction point by welding 38 radially more external.

This welding junction point is the edge outermost of the plate-shaped retainer that must be processed as a bulk product, which can be obtained from a process of stamping, separation or cutting. The singing of 37t cut on the outermost edge offers in stamping on the lower end of boss 37 formed by two triangles a Good welding contact, which can be applied upon request to resistance to a metal container. In particular, the edges that are projected during stamping on the front edge 37t are preferred during welding.

From the representations it follows that the instep line 37r extends essentially straight, see the figure 8a. In this straight line there is no cutting effect, only a stamping of the triangle-shaped configuration from the plane of the cover wall 21.

If the retained part of this ways or the retaining part according to figures 3 and 4 they must be arranged without any radial projection on the cavity 10, the arrangement is offered according to figures 6 and 8. In the Figure 6 is provided a cavity 11, which can have the configuration of a cavity 11 circularly according to the Figure 8 or of a surrounding groove 12 with the width continue b. A circular cavity 11 does not have to be necessarily circularly, but can be adapted to the outer shape of the plate-shaped retaining part 21, such so that its diameter D1 is slightly larger than the diameter d1 = 2r of the plate-shaped retainer, as described previously. The same applies to the surrounding groove 12, which extends throughout the periphery of the vessel wall 30, but only in two opposite places receives the piece of plate-shaped retention, whose projections 37 intended for the welding are in this cavity, but around ka housing cavity 10 for thickening the end of the clamp.

The cavities 11, 12, 10 have this way two steps, with at least two different depth planes, while virtually no projection is planned radial of the retaining part 21 in the form of a plate on the wall of the container 30.

The feeding of the retaining part 21 in plate shape (also designated as retaining part H) for vessel wall mounting is carried out as a product in bulk with handling for feeding from a classification device. It separates, grabs and welds laterally through a current pulse during the process butt welding.
