Description

The present invention relates generally to the panels which is surrounded by a frame on all sides Plate are formed.

It relates more closely, but not exclusively, to the case in such a panel for the manufacture of a door, in particular a cabinet door or a control cabinet door is needed, be it as a door wing or as a whole door.

This is the case, for example, if the pannel is a sheet of glass as a plate to at least part of the content of the appropriate cabinet visible.

It is also related to the construction of Display boxes known that a plate in such a way at all Pages is held by a frame, of which at least one page, in practice every page, on the one hand a profile section that has a support surface in its length in order to support or intercept the plate, and on the other hand one Fugendeckleiste has that turned on this profile section hangs or hooks and snaps into place against the plate press their support surface.

For example, this is the case in British Patent No. 16 02 730.

But in practice the Anha is used in the British patent ken in such a way that there is a rotatable assembly of the joint deck bar on the profile section allows.

Because of this fact, this hook must be spaced happen to the support surface of the profile section and the Einra Most necessarily happens between this support surface and the hook.  

This results in the pressure of the joint cover strip on the Plate is relatively poorly controlled, and that the Festhal ten of this plate is then relatively poorly secured.

The present invention generally relates to an (arrangement) Device that does not depend on any rotatable assembly disadvantages is advantageously exempt and on the contrary an ef efficient, unsafe holding of the plate.

Precisely, the subject is a panel, in particular a cabinet door and in particular a cabinet door panel, such that there is a frame for holding a plate to al len sides, of which at least one side on the one hand has a profile section, the length of a support has surface to support or intercept the plate, and on the other hand, one hooked onto the profile section and turned on snapped joint cover strip to the panel against its support surface press on; this panel is generally characterized by that, at the same time, the profile section is nearby ner support surface and protruding from this support surface a hook back in a direction perpendicular to it which extends on the side of this support surface, and to which the joint cover strip itself is engaged by one there is a hook-back in the opposite direction, this hook-in recess lines the joint cover strip inwards a cross profile in the form of a crosshead along one of its Edges, and the joint cover strip lies directly or indirectly the plate in question, through the back part of this Hook return, on the side facing the hook return of the Profile section is opposite, and on the other hand points the profile section at a distance from its support surface Snap shoulder on, facing in a parallel direction this support surface on the other side of his hook back jump extends with respect to this support surface, and to which the joint cover strip itself engaged by one in opposite in the set direction.  

So the one from the joint cover strip to the one to be held Plate exerted pressure directly on that of the profile section through the hook recess along one of the edges of this Joint cover strip in favor of a safe and efficient Holding the plate intercepted.

At the same time, it snaps into place at a distance from this hook along the other edge of the joint cover strip, and taking into account the corresponding lever arms remains the one for Si securing this engaging force advantageous ge moderate, without affecting their efficiency.

All the more so because of the elasticity of the foot edge trim is promoted to which your hooking back jump heard.

In short, the joint cover strip according to the invention is advantageous efficient and easy to use.

The figures illustrate the application of the inven tion for a cabinet 10 and for example for a control cabinet.

As is known, this cabinet 10 has a housing 11 and on the front of this housing 11 a movable or hinged panel 12 , which forms a door.

The corresponding devices are not based on the existing ing invention and are not described here.

As is also known, the panel 12 consists of a plate 13 , for example a glass pane, with a frame 14 around this pane 13 in order to ensure that it is held and pivoted with the housing 11 .

Set 14 A as vertical sides or posts of this frame and 14 B as horizontal sides or cross bars.

At least one of the sides ( 14 A), ( 14 B) of the frame ( 14 ) and in practice each side has on the one hand a profile section ( 16 ) which has a support surface ( 18 ) along its length in order to support the plate ( 13 ) to support or intercept, and on the other hand, a joint cover strip ( 20 A) or ( 20 B), the section ( 16 ) is hooked and engaged to press the plate ( 13 ) against the support surface ( 18 ).

In the embodiments shown here, a seal ( 21 ) is inserted between the plate ( 13 ) and each of the profile sections ( 16 ), and between this plate ( 22 ) and each of the joint cover strips ( 20 A), ( 20 B), a sealing cord ( 22 ).

These sealing cords ( 21 , 22 ), for example, adhere to the plate ( 13 ), for example by gluing.

According to the invention, the profile section ( 16 ) in the vicinity of its flat support surface ( 18 ) in the projection thereof in a direction D1 perpendicular thereto has a hooking recess ( 24 ) which extends next to this support surface ( 18 ) and with which the Joint cover strip ( 20 A) or ( 20 B) itself is engaged by a hook recess ( 25 ) standing in the opposite direction of the hook recess ( 24 ), and the profile section ( 16 ) likewise has a snap shoulder ( 18 ) at a distance from its supporting surface ( 18 ). 26 ), which extends in a direction parallel to the support surface ( 18 ) on the other side of its hook recess ( 24 ), and with which the joint cover strip ( 20 A) or ( 20 B) itself through a snap-in shoulder ( 27 ) is engaged, which is in the opposite direction to the locking shoulder ( 26 ).

In practice and in the Realisierungsfor men shown here, the support surface ( 18 ) of the profile section ( 16 ) belongs to a support plate ( 28 ) which extends in the transverse direction over the entire width of this profile section ( 16 ).

The support surface (18) extends more precisely along one of the edges of the support plate (18) [(28) n. D. Translator] and forms a local excess thickness on this.

The hooking recess ( 24 ) extends approximately parallel to the support surface ( 18 ).

It is offset with respect to this support plate ( 18 ), both in the direction D1 perpendicular to this and in the direction D2 horizontal to this.

In practice, it is carried by a rib ( 30 ) perpendicular to the support surface ( 18 ).

In the realization form shown in particular in FIGS . 1 to 7, this groove ( 30 ) originates from a counter-support plate ( 31 ) which is parallel to the support plate ( 28 ) and extends transversely to a part of its width, and with this support plate ( 28 ) in the projection on the side of the support surface ( 18 ), at the edge of this, forms a box volume ( 32 ) with a rectangular cross section.

The rib ( 30 ) extends backward with respect to the edge of this box volume ( 32 ) in the vicinity of the support surface ( 18 ).

The catch recess ( 24 ) extends obliquely starting from the groove ( 30 ) that supports it, in the direction of the support surface ( 18 ) and parallel to it, but without going beyond the contour of the box volume ( 32 ).

The locking shoulder ( 26 ), which has the profile section ( 16 ), also extends approximately parallel to the support surface ( 18 ).

It is offset with respect to this support surface ( 18 ) both in the direction D2 parallel to it and in the direction perpendicular to it D1.

In practice, the locking shoulder extends on the other side of the support surface ( 18 ) with respect to the hooking recess ( 24 ).

In other words, it extends on the other side of the support plate ( 28 ) with respect to the support surface ( 18 ) on the back part of this support plate ( 28 ).

More precisely, in the implementation forms shown here, this snap-in shoulder ( 26 ) consists of the edge of a wing ( 34 ), which the profile section ( 16 ) laterally has approximately perpendicular to its support surface ( 18 ) along the edge of the support plate ( 28 ), opposite to that along which this support surface ( 18 ) extends.

This wing ( 34 ) extends on the back part of the support plate ( 28 ) in the support surface ( 18 ) opposite Rich direction.

In the implementation forms shown, the Profilab section ( 16 ) has a further wing ( 35 ) which is mounted along the edge of the support plate ( 28 ), along which the support surface ( 18 ) extends, and like the previous one in this extends in the opposite direction.

The height of this wing ( 35 ) is greater than that of the previous wing ( 34 ).

Finally, the profile section ( 16 ) in the implementation forms shown here on the back part of the support plate ( 28 ), between the wings ( 34 ) and ( 35 ) and in the same direction as this, a stiffening groove ( 36 ).

In addition, according to the invention of the hook recess ( 25 ), which has a joint cover strip ( 20 A) or ( 20 B), this foot cover strip ( 20 A) or ( 20 B) along one of its edges inwards along a cross profile in the form of a crosshead .

The snap-in shoulder ( 27 ), which also has a joint cover strip ( 20 A) or ( 20 B), extends approximately parallel to its hooking recess ( 25 ).

As with the profile section ( 16 ), this latching shoulder ( 27 ) is offset with respect to this hooking recess ( 25 ) in one or the other direction D1, D2.

In practice, the locking shoulder ( 27 ) and the hooking recess ( 25 ) extend in opposite directions to each other.

In the forms of realization shown, the snap-in shoulder ( 27 ) belongs to a groove ( 37 ) which extends in the projection on the inner side of the joint cover strip ( 20 A) or ( 20 B).

The hooking recess ( 25 ) thus extends in a first direction D2, and the groove ( 37 ) to which the snap-in shoulder ( 27 ) belongs extends in a direction opposite to the direction D2.

In the realization form shown in particular in FIGS . 1 to 7, the joint cover strip ( 20 A) or ( 20 B) has an extension ( 38 ) perpendicular to the catch recess ( 25 ) beyond the groove ( 37 ) which has its snap-in shoulder ( 27 ) wearing.

In addition, in this form of implementation, the groove ( 37 ) forms a thickening ( 40 ) on its foot, which limits the snap-in shoulder ( 27 ).

Finally, the joint cover strip ( 20 A) or ( 20 B) in the implementation forms shown in length from place to place in projection on its inner side between the hooking jump ( 25 ) and the locking shoulder ( 27 ) stiffening grooves ( 41 ) with whose edge it lies on the profile section ( 16 ).

The joint cover strips ( 20 A) and ( 20 B) are the same overall.

Overall, they have an angular transverse profile with their hooking recess ( 25 ) parallel to a first wing ( 42 ) and their snap-in shoulder ( 27 ) perpendicular to a second wing ( 43 ).

In the realization form shown in particular in FIGS . 1 to 7, only the wing ( 42 ) has stiffening grooves ( 41 ) on its inner side.

For a joint strip ( 20 A) of a vertical side ( 14 A) of the frame ( 14 ), the angle generated by the two wings ( 42 ), ( 43 ) is rounded off broadly, first by a bevel ( 44 ) and then by a rounding ( 45 ), Fig. 5.

As a result, the stiffening grooves ( 41 ), which this joint cover strip ( 20 A) has a projection on the inner side of their wing ( 42 ), are unevenly high.

For a joint strip ( 20 B) of a horizontal side ( 14 B) of the frame ( 14 ), the angle formed by the wings ( 42 ), ( 43 ) is angular, since these wings ( 42 ), ( 43 ) have an edge ( 46 ) butt together, Fig. 6.

In any case, the joint cover strips ( 20 A) and ( 20 B) both have the shape of profile sections.

While the profile section ( 16 ) is preferably made of metal, these joint cover strips ( 20 A) and ( 20 B) are preferably made of plastic.

To produce a panel ( 12 ) according to the invention, the various profile sections ( 16 ) required for forming the frame ( 14 ) are first assembled after miter cutting to the correct length.

For example and as shown in FIGS. 1 to 7, this assembly can be done with the help of angles ( 48 ), the two wings ( 49 ) of which are inserted into each other in the box volume ( 32 ) of two profile sections ( 16 ) to be assembled.

If desired, these angles ( 48 ) are solidified with the profile sections ( 16 ) which they join together, for example with the aid of screws, not shown here.

Then the plate ( 13 ) is used, Fig. 7A, after the insertion of the seals ( 21 ) and ( 22 ).

Finally, the joint cover strips ( 20 A) and ( 20 B) are inserted.

For example, in the case of a joint cover strip ( 20 A), this is initially set at an angle to the profile section ( 16 ) on which it must be inserted, Fig. 7, then after its straight bend, the insertion of its hook recess ( 25 ) behind the hook recess ( 24 ) of this profile section ( 16 ) vorgenom men until this hooking recess ( 25 ) comes together with the groove ( 30 ) which carries the hooking recess ( 24 ) of the profile section ( 16 ), Fig. 2, so that their locking shoulder ( 27 ) with the snap-in shoulder ( 26 ) of this profile section ( 16 ) can be hooked on.

The seals ( 21 ), ( 22 ) are then slightly pressed and the hook recesses ( 24 ), ( 25 ) of the joint cover strip ( 20 A) and the profile section ( 16 ) are at the same time under a slight prestress.

As you can see, the joint cover strip ( 20 A) with the back of their hook recess ( 25 ) through the cooperation of the sealing cord ( 22 ) on the plate ( 13 ), which ensures a particularly safe and firm holding of this plate ( 13 ).

The joint cover strips ( 20 B) are inserted in the same way.

In the variant of the embodiment shown in FIG. 10, the groove ( 30 ) of the profile section ( 16 ), which carries its hook recess ( 24 ), is a part of the support plate ( 28 ) of this profile section ( 16 ), since there is no box volume on it see is.

At the same time in this implementation variant of the Profilab section ( 16 ) between this groove ( 30 ) and the support surface ( 18 ), in the projection, on the edge of the support surface ( 18 ) and to limit this Be another groove ( 50 ), the less high than the groove ( 30 ) is at a sufficient distance from the hook recess ( 24 ) to enable the insertion of the hook recess ( 25 ) of the joint cover strip ( 20 A) or ( 20 B) connected between it and the latter.

Finally, in this implementation variant, the wing ( 34 ) of the profile section ( 16 ), the edge of which forms the snap-in shoulder ( 26 ), is of sufficient height for the associated joint cover strips ( 20 A) or ( 20 B) to cooperate with one another Support stiffening groove ( 41 ), which is provided for this purpose on their wing ( 43 ), Fig. 9 and 10.

In addition, in the embodiment shown in FIGS . 9 and 10, the joint cover strips ( 20 A), ( 20 B) have no lengthening beyond the groove ( 37 ), to which their snap-in shoulder ( 27 ) belongs, since this groove ( 37 ) is itself extends inward along its corresponding edge in the projection.

In addition, no excess thickness is provided at the foot of this groove ( 37 ) in this implementation variant.

Otherwise, the arrangement is of the same type as that above described.

Of course, the present Er is also limited finding not only on the reali described and illustrated forms of application, but extends to every execution version riante and / or combination of their different elements.

In addition, the field of application of the invention is not unique limited to that of the control cabinets, but extends on the contrary, in the field of every possible application of Pa neelen of the corresponding type, for example in construction or in the Interior design.
