The present invention relates to a face of the tip (nozzle), designed for mounting boxes used, for example, for placement, retention and protection of various equipment, particularly electrical equipment, as well as for placement, retention and protection built in it electrical wires or cables required to service this equipment.

More specifically, the invention relates to a face of the tip containing the overlapping portion intended for closing the inner space of this mounting of the enclosure, and a mounting part that is used to secure this end of the tip at the bottom of the base mounting boxes.

Such end tip is designed to protect the end of the wiring duct from the shock and, especially, to protect personnel from the possibility of contact with the wires or cables installed in the mounting box.

However, these two functions are combined in the case when you want to avoid introduction of foreign bodies, such as electrical conductor, pins, staples, or screwdriver, the basis of such wiring duct.

In addition, the proposed end-tip performs a specific aesthetic function, in particular as a result of ensuring harmony the aqueous transition between the outer surface of the mounting box and the surface of the support base, this mounting frame is fixed.

The end tips of this type usually consist of two parts, namely the base and lid.

Such construction allows to achieve the desired aesthetic characteristics, in particular, due to the overlap of trim closing cover wiring duct with cover this end of the tip.

However, the installation of such end lugs on the end of the wiring duct is a relatively complex operation and causes certain difficulties in cases where the end of the wiring duct to be closed, is located in the corner of the wall.

At the same time, the implementation of complete end of the handpiece, consisting of two separate parts, is relatively expensive.

Also known monoblock end of the tip, i.e. the tip end, in the construction where the base and cover is made as a single part, made by moulding.

In order to ensure proper fixation of such end of the tip at the bottom of the base used wiring duct, it must be properly positioned before installing the closing cover this Assembly box.

However, due to the fact that the tip end is usually on what should overlap the end edge of the closing cover wiring duct, it is not always convenient to install the cover after attaching the gooseneck end of the tip on the bottom part of the Foundation of the wiring duct. Sometimes it is even impossible, in particular, in cases where the plot wiring duct, in question, is relatively short.

Thus, the main objective of the invention is to offer end tip, which is quite economical to manufacture and can be installed on the mounting box is especially simply and quickly.

To solve the task and in accordance with this invention serves the tip end of the above described type, in which the connecting portion forms an elastic connection, allowing some movement of the overlapping portions of this end of the tip relative to its mounting part.

Thus, in a preferred embodiment, the implementation of such end tip can be made as a single part and can allow fast installation with satisfactory mechanical strength, in particular, in relation to the shock.

We offer end tip simply can be set on the basis of the wiring duct or by its introduction in the direction of p is erpendicular supporting wall of the base, that allows installation in tight spaces, or by the insertion side end of the base mounting boxes, as we usually do.

Through the use of end of the handpiece in accordance with the proposed invention provides an opportunity to set a closing lid for closing this wiring duct after the end of the tip is mounted on the basis of this wiring duct.

Indeed, in this case, just enough to slightly move the overlapping portion of this end of the tip relative to its mounting part, already fixed on the basis of wiring duct, in order to slightly move these parts from each other in order to provide the ability to install the closing cap of this wiring duct, and then the elastic return of the overlapped portion of this end of the tip overlaps the edges of the end closing cap this wiring duct in order to provide reliable and acceptable in aesthetic terms the closed end of the wiring duct.

End of the handpiece in accordance with the invention also has other preferred characteristics, which are not restrictive, namely:

- mentioned elastic connection made in this way, the button to provide the opportunity for small translational movement in the longitudinal for this wiring duct towards its overlapping part to the mounting part;

this elastic connection is a hinge connection providing the opportunity for small angular deviations of the overlapped part of this end of the tip relative to its mounting parts;

- mounting portion, the overlapping portion, and an elastic connection to the end of the handpiece made in the form of single parts made by molding or other plastic material;

- overlapping part contains the closing wall of the internal cavity of this wiring duct and land cover that is designed to overlap the edge of the main closing cover wiring duct, and a closing wall and the portion of the cover is made as a single part by molding;

- elastic connection includes at least one corrugated plate, one end of which is connected to the mounting part of this tip end and its other end is connected with its overlapping part;

- wavy plate is made so that its waves were located on either side of the longitudinal vertical plane;

- wavy plate is made so that its waves were located on either side of the longitudinal horizontal plane;

- elastic connection is an elastic plate, which is mainly inclined between the mounting part and overlying a part of this end of the handpiece;

- elastic connection is a flexible plate, which is held in a horizontal plane in the direction of the longitudinal axis of the mounting box from the bottom of its overlapping part to the bottom of its mounting parts;

- elastic connection is a flexible plate, which is held in a horizontal plane in the direction of the longitudinal axis of the mounting boxes at a certain height relative to the basis of this wiring duct;

- elastic relation is implemented by forming a flexible plastic material, and in this case, overlapping and fastening end of this tip provided by molding a hard plastic material, and in this case the combination of the above elements as a whole forms a single monoblock item.

Other characteristics and advantages of the invention will be better understood from the following description of non-restrictive examples of its implementation, where there is reference to the application drawings, among which:

- figure 1 is a schematic perspective side view of the plot wiring duct, closed at one of its ends, the end tip in accordance with the invention;

It should be noted that in the application drawings, identical or similar parts of the structure that correspond to the various implementations of the invention, to the extent possible, identified the same items and will not be described in each example.

Figure 1 schematically shows an Assembly box 1 having about the relatively small size and also called wall plate, designed for installation in the electric wires or cables.

Usually the mounting box or wall plate 1 comprises a base having a bottom part 4, framed by the edges of the two longitudinal side wings 2, and this case, the base has a generally U-shaped cross-section.

In the example presented here, the implementation of longitudinal lateral wings 2 base mounting boxes contain bends 3 directed one towards the other in a plane essentially transverse with respect to these side wings 2.

In addition, in this here case, the basis of this wiring duct is divided into two longitudinal compartments with a Central longitudinal wall 5, having at its free end diverging flanges, and each of these edges directed toward the bend 3 of the corresponding longitudinal side of the wing 2 base mounting boxes.

Thus, we consider here the case of bottom portion 4 of the base wiring duct 1 is divided into two parts 4A, 4b. Each of these compartments of the base wiring duct has a generally U-shaped cross-section.

This Assembly box 1 is closed by a cover 6, which in this case contains the descending edge, providing closure of the outer surfaces ol the longitudinal lateral wings 2 base mounting boxes.

Of course, in accordance with another example implementation, not shown in the application drawings, it is possible to provide that the closing cover wiring duct 1 was a cover with straight edges, intended for insertion in a longitudinal groove provided on each of the bends of the side longitudinal wings Foundation of this wiring duct.

One end of the wiring duct 1 shown in figure 1, the closed end of the handpiece 100.

This end tip is designed to protect the end of the wiring duct from the shock, and also eliminates the possibility of access through the end of the electrical conductors or cables installed in the mounting frame, or prevent the introduction into the internal cavity of this wiring duct of foreign objects, such as an electrical conductor, pin, clip, screwdriver, etc.

In addition, this end of the handpiece 100 allows to significantly improve the aesthetic characteristics of this wiring duct, providing a visual harmonious transition between the outer surface of the cap that covers the basis of this wiring duct, and a support base on which the mounting frame is fixed.

As for base fixing this wiring duct, then ZV is camping speech can go about a vertical wall or partition.

The first preferred example of implementation of the end of the handpiece 100 in accordance with the invention will now be described in more detail with reference to figure 2-5.

End of the handpiece 100, represented in the drawings, includes an overlapping portion 110 and the mounting part 120 which is designed to secure this end of the tip at the bottom of the base mounting boxes.

The overlapping portion 110 this case contains a closing wall 114 of the internal space of the mounting box and land cover 111 that is designed to overlap the edge of the closing cap 6 to close this wiring duct (see, in particular, figure 1).

This section covers 111 overlapping portion 110 of the end of the handpiece 100 includes falling edges 112, 113, overlying the descending edges 6A, 6b closing cover 6 mounting boxes 1.

The plot covers 111, 112, 113 and end wall 114 overlying portion 110 of the end tip this case made as a single part.

In addition, the tip end 100 includes a mounting part 120 which is designed to secure it on the bottom part 4 of the reason of this mounting boxes.

This case, this mounting part 120 and the overlying portion 110 of the end of the tip to form a single item, issue Lannoy by forming one or more plastic materials.

This case, this mounting part 120 includes two legs 121, 122, and each of these legs is designed for installation in one of the compartments wiring duct 1 and is superimposed on the bottom portion 4A, 4b of each of these compartments.

On each of these legs 121, 122 in their end zones, which are located side overlapping portion 110, posted by guide bushing 125, 126 that extends essentially perpendicular to the foot and, more specifically, in a direction perpendicular relative to the bottom part 4A, 4b of the mounting base of the enclosure, and which is the preferred way has a height essentially equal to the depth of the base wiring duct (see in particular figure 4).

Each guide sleeve 125, 126, representing the channel has a cylindrical shape, serves to introduce nail fixing each of the legs on the wall, which is the bearing surface for the given wiring duct.

This nail fastening passes through the base mounting boxes in order to gain a foothold in reference to this wiring duct wall.

The preferred manner the upper end of each of the guide bushings 125, 126, through which is inserted a nail fixing, is located flush with the tops of the side longitudinal wings 2 mounting boxes 1.

Thus, in the process itself remarkably similarly is the impact of each of the legs mount to the base of this wiring duct guide sleeve forms a stopper free motion of the hammer, eliminating annoying wing damage the Foundation of the wiring duct.

This circumstance is particularly favorable in the case of trunking small size, in which the inner space of this wiring duct is relatively constrained, and towards the bottom of the base which as a consequence it is often difficult to access for itself remarkably similarly nails fastening the tabs to the bottom of the base.

In the example implementation shown in figure 2-5, each guide sleeve 125, 126 made in the form of a relatively massive part, forming a kind of thickening at the end of each of the mounting pads 121, 122.

In addition, each of these mounting pads 121, 122 are connected to the overlying part 110 or, more precisely, with the end wall 114 by means of a connecting part 123, 124.

This case, each guide sleeve 125, 126 is located at the junction between the connecting part 123, 124 and foot mounting 121, 122.

In accordance with the method of implementation, is presented in figure 2-5, each connecting part 123, 124 formed wavy plate or a branch.

One end of this plate or branches connected to the end wall 114 of the overlapped portion 110 and its other end connected to the outer surface 125, a relatively Massey the Noah side foot mounting, where implemented, each guide sleeve 125, 126.

The sinuosity of each branch or each plate 123, 124, forming the connecting part, implemented on either side of a vertical plane passing along the axis X1 or x2, parallel to the longitudinal axis X of this end of the tip, which is also the longitudinal axis of this wiring duct.

This connecting part 123, 124 forms an elastic connection between the mounting part 120 and the overlapping part 110, while allowing for slight movements of this overlapping portion with respect to the mounting part in the case, when this end of the tip is mounted on the end of the considered mounting boxes.

This circumstance is particularly favorable in the case where, as shown in figure 2-5, the overlapped part, the fastening part and the connecting part of this end of the tip to form a single item, made by molding one or more plastic materials, and when the overlapping portion of this end of the handpiece contains some region of the cover with the descending edges, as mentioned above.

Thus, we consider here the case of setting the end of the tip to the base wiring duct is otnositelnosti and can be performed even when access to the end of the base wiring duct is difficult, as it happens, in particular, in the case when the end of the base wiring duct is placed in the corner of the supporting wall.

In the case where access to the end of the wiring duct is difficult, the mounting end portion of the tip can be installed on the bottom of the base mounting boxes along the fitting direction, essentially perpendicular to the longitudinal axis X of this wiring duct.

At the same time, in those circumstances, when the location of the end of the wiring duct allows this, consider the tip end can be inserted into the base of this wiring duct along its longitudinal axis X.

The mounting portion 120 of the end of the tip is fixed by itself remarkably similarly her nails to the bottom of the base of this wiring duct.

Then the overlapping portion 110 of the end of the handpiece 100 is slightly shifted incremental fashion along the longitudinal axis of the mounting box in the outward direction with respect to its base thus to be able to easily install this Assembly box closing the lid due to the fact that the edge of this cover when it is in the immediate vicinity of the end of the wiring duct.

Indeed, in this case, PE is Krivaya part of this end of the handpiece is removed from its mounting part, to facilitate installation of this Assembly box closing the lid.

Finally, the elastic return of the overlapped portion end of the tip to its original position plot cover this overlapping part provides overlapping edge closing cover wiring duct in place based on this wiring duct.

This elastic connection between the mounting part 120 and the overlapping part 110 end of the handpiece 100 can provide, in addition to progressively move it to the overlapping part to the mounting part, and a small yet pivotal movement of these two parts relative to each other.

As is more clearly shown in figure 4 and 5, when offered the tip end placed on the end of the base mounting boxes, bushings rise perpendicular to the bottom part of the Foundation of the wiring duct, and the upper ends of these guide bushings are clamped under the bends 3 longitudinal lateral wings 2 the Foundation of the wiring duct.

The overlapping of the discussion here end tip closes in the transverse direction of the mounting box their portion of the cover overlying the end part of the cover of this wiring duct.

Shown in figure 2-5 end tip also allows you about is the ensure the possibility of its attachment to the base mounting boxes by fixture with two holes 129, 130 provided on each of the free ends of the legs of the fasteners 121, 122.

At the same time located against each other, the inner longitudinal edges 127, 128 of each of these mounting pads 121, 122 contain this case located against each other cutouts a, a, made in the form of part of a circle and defining between themselves a slot designed for possible accession of the fixing portion of this end of the tip to the base of the mounting box using the body mounting type plastic dowel or pin.

This method of attachment may be considered only in the case when this Assembly box is a one-sheet or contains only one compartment that does not match the versions of the implementation shown in the application drawings.

Other examples of implementation can be considered for forming the connecting parts 123, 124, forming an elastic connection of the mounting part 120 with overlapping part 110 end of the handpiece 100.

Among these other examples of implementation there are examples, schematically presented in Fig.6-11.

Indeed, as can be seen in Fig.6, the connecting portion 123, 124 of each of the mounting tabs 121, 122 with the overlying part of this end of the tip is formed by a continuation of the legs of the fastening.

In addition to the CSO, in accordance with a simplified way of implementing the outer wall of each guide sleeve 125, a is a wall in the shape of the surface of the cylinder rotation.

In accordance with an example implementation, schematically presented in Fig.7, each connecting part 123, 124 of each of the mounting tabs 121, 122 with overlapping part 110 contains two branches 123A, 123b, 124a, 124b, passing from one end of each of the legs 121, 122 (where is the guide Bush) on either side of its longitudinal edges 127, 131, 128, 132, and mentioned branches 123A, 123b 124A beaches and, 124b form design type connection of the fork legs, fastening with an overlapping part 110.

In accordance with another example implementation, described in more detail on Fig, may be provided to wavy connecting part 123 of the mounting part 120 of the end of the tip with its overlying part 110 had waviness on either side of its longitudinal horizontal plane.

Can also be provided to each connecting part 123 was formed by a plate which is held between the outer wall 125 of the guide sleeve 125 and the overlapping part 110 is normally in an inclined direction, as schematically shown in figure 10.

In implementations, schematically presented in Fig.9 is 11, each connecting part 123 of the end tip is located between the outer wall 125 of the guide sleeve 125 and the overlapping part 110 and is at a certain height in relation to each foot of mount 121.

As can be seen in Fig.9, the connecting plate 123 is located approximately at the same height with the upper end of the guide sleeve, as in the example implementation presented figure 11, this connecting plate 123 is located approximately at half the height between the foot of mount 121 and the upper part of the guide sleeve 125.

In order to achieve an elastic connection between the mounting part 120 and the overlapping part 110 end of the handpiece in accordance with the invention, can also be tformat connecting part from a plastic material, which is flexible than the material of the fixing part, and the material of the overlapping part, made of hard plastic material, so that the above set of items represented a single part, made of two materials with different mechanical properties.

As possible to use in this case, the plastic material may be mentioned flexible and rigid polyvinyl chloride PVC.

<> The invention is in any case not limited to the described and represented here by examples of its implementation. Specialist in the art can make in these examples, any variants, without leaving the framework of the invention.

In particular, in accordance with the non-represented here by a variant of realization, can be considered the tip end of the end of the handpiece shown in figure 2, but with only one foot mounting (for example, similar to one of the legs of the fastening end of the handpiece shown in figure 2), holding one guide sleeve and connected with the overlapping part with the help of wavy connecting part forming an elastic connection between overlapping and fastening parts of this end of the tip.

In accordance with another not presented here option for you to consider edge tip of the type shown in figure 2, but with only one foot mount (similar to the one of the legs of the fastening end of the handpiece shown in figure 2), which is twice the width relative to the width of the tabs of the mounting end of the handpiece shown in figure 2, and holding two identical and parallel to each other, the guide bushing, and this foot attachment a double-wide is connected with the cross-the living part of this end of the handpiece by means of two wavy connecting parts, forming an elastic connection and the parallel between the guide sleeve and overlying a part of this end of the tip, each of these connecting parts departs from the outer wall of the guide sleeve.
