Abstract

A mounting element (10) that is fixable without tools in an opening (30, 38) in a component (32, 44) has a thickness, width and length and an outer side (12), wherein the mounting element (10) is not expandable in the thickness or width direction and has on its outer side (12) at least one cutout (22) which is delimited by a boundary and into which a restorable barbed arm (24) having a barb (14, 16) at its free end projects in a manner protruding from a peripheral region of the cutout (22). The barb (14, 16) projects beyond a plane, defined by the boundary of the cutout (22), towards the outer side (12) of the mounting element (10). Insertion into a receiving cutout opening (30, 38) in the component (32, 44), said receiving cutout opening (30, 38) being adjoined by a receiving cutout (34, 40), delimited by an inner side (36, 42), in the component (32, 44), results in the barbed arm (24) being bent, forming a pressure force of the barb (14, 16) against the inner side (36, 42) of the receiving cutout (34, 40) in the component (32, 44), and in a retaining force of the mounting element (10) in the receiving cutout (34, 40) in the component (32, 44). Pushing through a rear-engagement opening in the component results in the barbed arm (24) being bent, forming a restoring force, acting on the barbed arm (24), for engaging behind the opening in the component by way of the barb (14, 16). From the peripheral region of the cutout (22), from which the barb (24) protrudes, there extends a lever protrusion (26) that extends obliquely outwards and faces away from the barbed arm (24), said lever protrusion (26) exerting an additional pressure force on the barb (14, 16) upon introduction into a receiving cutout opening (30, 38) in the component (32, 44), said additional pressure force likewise acting in the direction of the pressure force, brought about as a result of the bending of the barbed arm (24), of the barb (14, 16), wherein the lever protrusion (26) itself likewise exerts a pressure force on the inner side (36, 34) of the receiving cutout (34, 40) and thus brings about an additional retaining force, or said lever protrusion (26) exerting an additional rear-engagement releasing movement and/or a rear-engagement preload on the barb (14, 16) in the event of introduction into a rear-engagement opening in the component, as a result of an associated inward movement.

Description

Tool-free mounting element

The invention relates to a tool-attachable mounting member that can be used in an opening of a component, for example, to connect the said component with a second component or to attach an attachable to the mounting member further part on the component or to a one-piece with To attach the mounting member formed attachment part on the component. The component preferably comprises wood material and in particular pressed chip material. Other materials such as metals or plastics or pressed material particles consisting of materials other than wood, in particular elongated material particles, can also be used for the component to which the mounting element can be fastened without tools in an opening of the component. In particular, but not exclusively, the mounting element can find application in the furniture industry. Main purpose of the fastened in an opening of a component tool-free mounting member is to be found in the furniture industry, namely for the assembly of furniture such as shelves, cabinets, desks or the like. Furniture made mostly of plate-shaped wooden parts. To connect such components are so-called wooden dowels, which, however, if they are not glued, build no resistance to tensile loads. For this reason, dowel or plate-like mounting or connecting elements have already been proposed in the prior art in a variety of design, having a quergeriffelte outer structure or saw tooth-shaped annular beads, which upon insertion of the mounting member in a component opening in this against tensile stresses to lock automatically. For the most part, however, this type of mounting elements is used in connection with glue or adhesives. Examples of mounting elements of the aforementioned type are described in GM 78 25 669 U l, GM 85 36 350 Ul, G 87 13 028 Ul, G 91 10 117 Ul, DE299 03 925 Ul, DE 202 05 289 U l, DE 20 2005 021 228 Ul, DE 20 2008 008 369 U 1, DE 39 03 146 AI DE 196 14 890 A1, DD 83 875, EP 0 309 790 A1, CH 396 374 and GB 1 162 282.

In addition to substantially peg-shaped, ie dübeiförmigen mounting elements for the connection of two components also exist oval-shaped plate-like connecting elements, such as those offered by Lamello AG, Switzerland. Examples of such plate-like connecting or mounting elements are in DE 20 2008 016 179 U l, DE 28 16 134 AI, DE 196 04 243 AI, EP 1 630 427 AI, EP 1 980 758 A2, AT 373 046, ES 2,003,266 and US 5,096,328.

In order for a mounting element inserted in an opening of a component in a first direction to remain secured in the opening against a return movement, it requires barb-like wedges of the mounting element with the component or with the opening. Examples of such anchored by the barb dowel anchors are described and shown in DE 25 07 536 AI and FR 2 257 809 AI.

Another connecting element with integrated snap connection is known from DE 10 2010 051 372 AI.

Connecting elements according to the preamble of claim 1 are described in US 4,610,589 A, US 2008/0263834 AI and DE 44 03 389 AI.

The object of the invention is to propose a particularly simple and comfortable to use mounting element for tool-free attachment in an opening of a component, wherein the mounting member is held automatically with sufficiently high holding forces in the opening of the component when it has been used there. In addition, the construction of the mounting element should be simple and inexpensive. To solve this problem, an invention in an opening of a component tool-mountable mounting member is proposed, which is provided with

a thickness, width and length and with an outside,

- wherein the mounting element in thickness and width extension is not expandable and on its outer side has at least one bounded by a boundary recess in the protruding from an edge region of the recess projecting a resilient barb arm with a barb projection at its free end, and

- Wherein the barb projection protrudes beyond a defined by the boundary of the recess level to the outer surface of the mounting member and

When pushed into a receiving recess opening of the component, which is followed by a receiving recess limited by an inside in the component, to a curvature of the barb arm to form a contact force of the barb projection against the inside of the receiving recess of the component and to a retaining force of the mounting member in the Recording recess of the component leads

or

when pushing through an engageable behind opening of the component to a curvature of the barb arm to form a force acting on the barb arm restoring force for engaging behind the opening of the component by the barb projection leads.

In this mounting element is provided according to the invention,

that extends from the edge region of the recess, from which protrudes from the barb arm, an obliquely outwardly extending, the barb arm facing away lever projection,

- Exerts an additional contact force when introduced into a receiving recess opening of the component on the barb projection, which also acts in the direction of the resulting due to the curvature of the barb arm contact pressure of the barb projection, wherein the lever projection itself also a contact pressure on the Inside the receiving recess exerts and thus causes an additional retention force,

or

which, when introduced into a grippable opening of the component due to an associated inward movement exerts an additional rear engagement disengagement and / or a rear grip bias on the barb projection.

The mounting element according to the invention can be used both in a component opening with adjoining receiving recess (thus, for example, in a bore in the component) and in an aperture which can be grasped behind, ie in a hole of the component; In both cases, the inventive construction of the mounting member ensures that this component is reliably held when tensile stresses occur. The mounting element according to the invention can be used without tools in the opening of a component. Thus, if two components are connected to the mounting element according to the invention, then the two components are connected to each other substantially captive. The mounting element according to the invention is not expandable in terms of its thickness and width extension; it may be hollow or made of solid material, wherein the elasticity of the barb projection and arm must be ensured by providing for the presence of the recess in the outside of the mounting member. It also requires no insert element in the mounting element, so that this anchored in the component or in the opening of the component.

According to the invention, the mounting element has at least one barb arm with a barb projection, wherein the arm projects with the projection into a recess on the outside of the mounting element. The recess is dimensioned in relation to the depth extent such that the barb projection or the barb arm can retreat when the mounting element is inserted into the opening of the component. Due to the resulting in a deformation of the barb arm mechanical Stress arise restoring forces, which cooperate with the component or with the opening of the component in order to fix the mounting member in the component against backward movements. In this case, this holding mechanism is based either on a gripping behind the opening edge in the component or on the pressing of the barb projection against the inside of a receiving recess in the component (for example, bore), wherein added in pressboard material or generally wood or other having a rough surface component materials, that the barb projection presses into the material of the component and is held there in a form-fitting manner substantially.

The decisive factor is that the barbed arm with barbed projection can retreat to build up its contact force or retention force. This means that the retaining projection should not be designed as an annular bead but rather in such a way that optionally distributed over the outer surface or the circumference of the mounting element a plurality of individual barb arms are arranged with barbs projections.

In the mounting element according to the invention is further provided that extends from the edge region of the recess from which protrudes from the barb arm, an obliquely outwardly extending, the barb arm facing away lever projection, which exerts an additional contact force when introduced into a receiving recess opening of the component on the barb projection which likewise acts in the direction of the contact force of the barb projection arising as a result of the curvature of the barb arm, wherein the lever bump itself also exerts a contact force on the inside of the receiving recess and thus causes an additional restraining force, or as a result of insertion into a tangible opening of the component an associated inward movement exerts an additional rear-disengaging movement and / or a rear-grip bias on the barb projection.

According to the invention, therefore, the barb arm and lever projection or lever with lever projection are connected in opposite directions from one from the middle section. The inward movement of the lever projection during insertion of the mounting element into the component opening due to the abutment of the lever projection on the opening edge or on the inside of the receiving recess causes an increased disengagement movement and thus an increased contact pressure of the barb projection for engaging behind the opening of the component or for pressing against the Inside of the receiving recess (eg hole in the component). In addition, however, the lever projection itself provides additional retention force by being biased toward the outward motion by inward movement by the internal material stresses.

The mounting element according to the invention is expediently made of plastic (for example in injection molding technology). Components connected by means of the mounting element according to the invention can therefore rest reliably against each other permanently. If the components are (additionally) glued together (glued), it requires no hardening of the adhesive contacting components, which also simplifies this part of the assembly of the components.

In an advantageous embodiment of the invention it can be provided that the mounting element has on its outer side a plurality of in particular opposite or in particular symmetrically distributed or arranged alternately barbs projections or pairs of each cooperating barb projections and lever protrusions.

As far as the contour of the mounting element according to the invention is concerned, it is possible according to the invention that the mounting element is designed as a pin, bolt, angle piece, plate or strip-shaped or with a plurality of arms T-piece, cross or star-shaped and / or that the mounting element for material saving reasons Recesses, a hole, blind holes or the like. Free spaces. As already mentioned above, the mounting element can be used to attach, for example, an integrally connected to the mounting member mounting part (hook, knob or the like.) To the component by the mounting member is inserted into the opening of the component and the relevant attachment part of the mounting element and thus protrudes from the component.

But it is also possible that the mounting member is inserted at its two opposite ends in each case the opening of two components to then connect these two components together (for example, as in the connection of a shelf or cabinet intermediate floor with the side walls of the cabinet or Shelves or the top wall or bottom wall element with a side wall element of a cabinet or shelf body). In this case, both ends of the mounting element then have the previously described barb arms and barb projections or Hebelvor- jumps.

In a further advantageous embodiment of the invention can be provided that the mounting element itself is formed in several parts by the opposite ends of the mounting member are formed as separate Montageelement- parts and that the two mounting member parts are connected by means of a latching connection element, which formed in the two mounting element parts receiving cavities can be used secured against moving out or which is integrally formed with one of the two mounting element parts and can be secured against being moved out into a receiving cavity formed in the other mounting element part. The connection of two mounting element parts to a common mounting element and thus to the connection of two components, as described above, can be realized according to the invention without simultaneous formation of barb arms and barb projections or lever projections. Insofar, according to the invention, this is therefore an independently functional aspect of the invention that can be implemented independently, and that can also be implemented without the other aspects of the invention described above. In this independent variant of the invention, for example, the two separate mounting element parts can first be used in openings provided for this purpose of two components, in order then to secure the two components to one another via the assembly element parts to be joined thereto. In this case, it can be advantageously provided that the mounting element part or each mounting element part provided with the receiving cavity has at least one latching projection which protrudes inwardly into the receiving cavity to form a positive connection with a corresponding latching recess of the latching connection element when the mounting element part is inserted into an opening of a component. Due to the design of the locking projections and locking recesses, the two mounting element parts can be telescoped, with a return movement is prevented. The latching connection element is therefore unidirectional in the relevant assembly element part, namely against outward movements, secured. The one or more locking projections expediently each have an outwardly projecting flexible latching arm which, when the mounting element part is inserted into the opening of the component, generates additional forces on the latching arm for biasing the latching projection in the direction of the latching recesses of the latching connection element. As a result, the latching connection element is held even more reliably in the mounting element part. The latching connection element can have a plurality of projections, in particular annular beads, with latching recesses arranged between them.

In the case of the multipart design of the mounting element, at least one of the two mounting element parts has the above-described receiving cavity for the latching connection element. It should be noted at this point that more than two mounting element parts can be assembled to form the mounting element. In each case zusammenzusteckende mounting element parts must then have at least one latching connection element. If the mounting element part, in which the latching connection element is inserted, additionally has a barb arm and barb projection, then it is expedient for the latching connection element to abut against the barb arm or barb projection from the inside and possibly push it outwards, for which purpose it is expedient if barb arm is directed obliquely inwards into the receiving cavity. In this case, it may then be provided that, in the mounting element part provided with the receiving cavity or in each mounting element part, the recess into which the barb arm projects, opens into the receiving cavity and the latching connection element, upon receiving its respective end, into a receiving cavity of the respective other mounting element part on the barb arm is applied.

As mentioned above, the mounting member may comprise a mounting member for another component, an attachment member such as a hook, a fitting member, a trim member, and / or a handleable handling member such as a hook. a handle, a knob, a button or the like. exhibit. With the help of the mounting element according to the invention, which automatically ensures against re-moving out of the opening of the component in this, it is now also possible to provide, for example, in a cabinet or shelf body or in a frame for fixing a rear wall. For this purpose, as compared to the previously described independent aspect of the invention provided that the mounting member is formed as a plate-shaped Inneneckverbindin- tion element for two wall elements such as a side and a bottom wall element or a side and a top wall element of a cabinet or shelf frame or a frame and an upstanding Mushroom head, such as B. Spreader pin for plug connection with openings in a wall of the elements enclosed rear wall or in that the mounting element is designed as a plug in a wall element such as side, bottom or top wall element of a cabinet body or a frame mounting member and a transverse to the insertion direction projecting spigots Connector having openings in a wall of the elements enclosed rear wall.

In the previously described inventive variant of the inventive mounting element, this has a plate-shaped plug-in element, which may be formed for example as Inneneckverbindungselement can. This plate-shaped plug-in element can or the like with the above-described barb arms or projections. be provided other features to be anchored in a component. Alternatively, however, the plug-in element can also be arranged and fixed in another way, for example adhesively, in the associated opening of the component. It is crucial that a plurality of such mounting elements are used, along the edge of a defined by side, bottom and top wall elements frame (such as cabinet or shelf body), and then to fix at these inwardly projecting mounting elements a rear wall, of the previously mentioned wall elements of the frame is enclosed. By enclosing the rear wall by the wall elements, the body is secured against shear forces and stable. The mounting elements thus serve to mount the rear wall; they themselves can be fixed or received in corresponding receptacles of the frame, such as, for example, the known oval-shaped plate-shaped mounting elements.

In a further advantageous embodiment of the invention can be provided that the component or at least one of the components to be connected to the mounting member is in particular a round, square or polygonal tube.

In a further advantageous embodiment of the invention it can be provided that the mounting element is designed as a bolt with a slotted mushroom head with elastic Umgreifvorsprüngen, over and from the an opening exhibiting attachment with this opening for the purpose of mounting the on-building component to the bolt receiving component can be pushed and removed while retaining the bolt in the component.

Further, a cap with a locking element for placement on the mushroom head under penetration of the locking element between the Umgreifvorsprünge and thus to block the Umgreifvorsprünge be advantageous.

The invention will be explained in more detail below with reference to a plurality of exemplary embodiments, which are shown in the figures, in which the According to the invention provided lever projections for reasons of better clarification of the applications and possible design applications of the invention are not shown in the drawing. A first embodiment of the mounting element according to the invention is shown in FIGS. 1-4. There is a dowel-like, cone-shaped mounting member 10 can be seen, the substantially cylindrical contour is not expandable. The mounting member 10 is made of plastic, for example. On the outer side 12, the mounting element 10 in this embodiment has a total of four barb projections 14,16, wherein in each case two diametrically opposed barb projections 14 and 16 are arranged at each axial end 18,20. The barb projections 14 are disposed within recesses 22 in the outer side 12, in which they can dodge into it. The barb projections 14 are located on flexible barb arms 24. Each barb arm 24 has at its opposite end of the barb projection 14 a lever projection 26 which, as shown in FIGS. 4.1 to 4.7, cooperates with the associated barb projection, so that both keep the relevant end of the mounting member 10 in an opening (hole) of a component against backward movement.

The mounting element 10 may additionally have at least one further barb projection 15 and / or thickenings 15 '(see, for example, also FIGS. 12.13 to 12.15 and FIGS. 36.1 to 36.3), which further enhances the securing of the mounting element 10 in the bore of a component the mounting member 10 acts tensile forces.

FIG. 2 shows an alternative embodiment of the mounting element 10 with longitudinal ribs 28 in the middle region of the outer side 12.

A similar embodiment of the mounting element according to FIG. 2 is also shown in FIGS. 3.1 to 3.3 shown. It should be emphasized at this point that, although in Figs. 1-3, the barb projections 14 are always shown in combination with lever projections 26, but the lever projections 26 are not necessarily required to securely hold the mounting member 10 in the component. In principle, it suffices to provide only the barb projections 14 (see eg FIGS. 6.1 and 6.2). In some embodiments of the invention, it is also possible to work only with the previously described lever projections 26. In the Fign. 4.1 to 4.7 is the assembly process for connecting two components by means of the mounting member 10 according to one of FIGS. 1 to 3 shown. First, the end 18 of the mounting member 10 is inserted into an opening 30 of a component (for example, pressboard) 32. In this exemplary embodiment, the opening 30 is a receiving recess opening, which is adjoined by a receiving recess 34, for example cylindrical or in any desired shape, in the component 32. At the beginning of the insertion movement (see FIG. 4.2), the barb projections 14 are moved further into the recesses 22 of the mounting element 10. Upon further insertion of the mounting member 10 now reach the lever protrusions 26 in contact with the inside 36 of the receiving recess 34. Here, the lever protrusions 26 bend inward, which due to the material stresses to radially outward biases both the lever projection 26 itself and the barb projections 14th or barb arms 24 leads. In the situation according to FIG. 4.3, the push-in movement of the mounting element 10 into the one component 32 is completed.

As shown in FIGS. 4.4 and 4.7 can be seen, a second component 44 can now be pushed onto the other end 20 of protruding from the first component 32 mounting member 10, which is also formed in this embodiment via an opening 38 with subsequent receiving recess 40. The barb projections 16 and the lever projections 26 at the second end 20 of the mounting member 10 act with the second component 44 and with the inside 42 of the receiving recess 40 in the second Component 44 together, as previously with reference to FIGS. 4.1 to 4.3 has been described. The final connection state of both components 32, 44 is shown in FIG. 4.7. In the Fign. 5.1 to 5.3, a multi-part mounting member 100 is described, which consists in this embodiment of two mounting member parts 102,104, which are nestable. For this purpose, one mounting element part 102 is integrally connected to a latching connection element 106. This latching connection element 106 has bead-shaped latching projections 108 with latching recesses 110 arranged between them, into which latching projections 112 dive onto flexible grid latching arms 114 carrying them. The latching arms 114 protrude outwardly, whereby the inwardly biased voltage on the latching projections 112 increases when the respective mounting member 104 is inserted into an opening of a component. The mechanism of action which takes place when mating the two mounting element parts 102 and 104 via the latching connection element 106, which in fact protrudes into a receiving cavity 116 of the mounting element part 104, is described with reference to FIGS. 30.1 to 30.4, wherein the multipart mounting element shown in these figures is formed in three parts. The individual parts of this three-part mounting element 100 'are shown in FIGS. 27.1 to 27.6, 28.1 and 28.2, 29.1 to 29.3 (alternative with several pairs of locking arms 114 and latching projections 112 per mounting element part 102,104 and without lever projections on the barb projections 14) and with respect to its assembly in FIGS. 30.1 to 30.4 shown.

In the Fign. 5.1 to 5.3 (and in the other figures given above), the mounting element parts, which can be plugged together in this embodiment by means of the latching connection element, also also provided with the barb projections and the lever projections, but this need not necessarily be the case.

In the Fign. 6.1, 6.2, 7.1, 7.2, 8.1 and 8.2 are shown various embodiments of mounting elements 10 ', in which the ends to which components to be joined together can be attached, in different Alignments are arranged. Thus, the mounting element can be used as an angle element (see Figures 6.1 and 6.2, where the lever protrusions are not expressly shown, but nonetheless exist) as a T-connector (see Figures 7.1 and 7.2) or as a cross element (see Figures 8.1 and 8.2). In the Fign. 6.1 and 6.2 it is shown that the mounting member 10 'has barb projections 14, the levers associated therewith are not shown for reasons of clarity, but still present. FIGS. 9.1 and 9.2 show the application of the connection of a first component 46 via the mounting member 10 with a hollow strand-shaped second component 48 in this embodiment. The component 48 may consist of "smooth" material, such as plastic or metal, and has an opening 50 into which the barb projection 14 of the mounting element 10 dips. The attachment of the mounting member 10 to the first component 46 can, as described above with reference to FIGS. 4.1 to 4.3 explained and shown in these figures, done. It is also possible to connect two components of the type of the component 48 with the mounting element 10. The Fign. 10.1 to 10.6 show the configuration of a mounting element 10 "in plate-like configuration and in turn with barb projections 14 and corresponding lever projections 26 arranged in pairs In this variant, the mounting elements 10" are shown as inner corner connecting elements (see FIG Plug-in elements formed in side walls of a carcass. The body has a top wall element 52, a bottom wall element 54 and two side wall elements 56. In these elements, slot-shaped recesses 58 are located in the middle areas and at the ends of the wall elements, into which the plate-shaped mounting elements 10 "are then inserted, in which case it is to be noted that the configuration of the inner corner connecting elements according to the mounting element 10" of FIG. 10.1 are provided with two slot-shaped recesses 58 cooperating barb projections and lever projections along two edges of the mounting member 10 ", while those mounting elements (see 10"'in Fig. 10.4), not in the Corners are arranged, only along one edge barb projections and possibly lever projections may have. When the body is constructed as shown in Fig. 10.4, as shown in Fig. 10.5, a back wall 60 can be moved against the mounting members projecting inwardly from the body. These mounting elements 10 "and 10"'have spreader pins or mushroom heads 62, are pushed over the openings 64 in the rear wall 60. In the assembled state (see FIG. 10.6), the top, bottom and side wall elements 52, 54 and 56 surround the peripheral edge of the rear wall 60 on all sides.

An alternative embodiment for the mounting elements 10 "and 10" 'is shown in FIGS. 11.1 to 11.3 shown. The there reproduced mounting member 10 "" has a plate-shaped part 66 which carries a spreader pin 62 and from which a dowel-like projection 68 protrudes, which like one of the ends 18,20 of the mounting member 10 as shown in FIGS. 1.1 to 1.4 can be configured. The extension 68 is inserted into a bore (receiving recess) of a component (in this case, for example, cover, base or side wall element 52, 54, 56, as shown in FIG. 10.4), and thus the mounting element 10 "" can serve to fix the rear wall 60, as indicated in Fig. 10.5 for the previously described embodiment.

In the Fign. 12.1 to 12.12 are again various design options for the connection of side wall panels and shelves, of the elements of a furniture body or the like. shown. Here are how the Fign. 12.1 to 12.7 show, inserted in the back of the body 70 in holes in the wall elements of the body 70 mounting members 200 which are anchored in the body 70, as it is based on the embodiments of FIGS. 1 to 4 is shown. The mounting elements 200 thus have, in addition to its anchoring portion with the barb projections and possibly lever projections on a mushroom head 62 with elastic Umgreifvorsprüngen 63, wherein over all mushroom heads 62 then the rear wall 60 can be plugged. This rear wall 60 in turn has openings 64 which are pushed onto the mushroom heads 62. This is shown in FIG. 12.6. FIG. 12.7 shows an embodiment of a mounting element 200 'similar to that of FIGS. 12.1 to 12.3, whereby all However, the mushroom head 62 is not designed as a spreading head. When using the mounting member 200 'for fixing the rear wall, however, this should then rest on the rest of the body, so then through the openings 64 of the rear wall 60 through the mounting elements 200' in the holes in the body 70 (see Fig. 12.4) are inserted can. The order of installation is therefore slightly different here than with reference to FIGS. 12.4 and 12.5 and 12.6 for the mounting elements 200 with trained as spreading mushroom heads 62 shown. FIGS. 12.8 and 12.9 show the interaction of several connection systems, being used as a substitute for the known wooden dowels mounting elements according to the invention and additionally the joining techniques, as described in German Patent Application 10 2012 219 154.2 of 19 October 2012, the contents of which are hereby by Reference is made, so that the content of the patent application is also the subject of the present patent application. In Fig. 12.11 is again shown how then additionally can be used with Inneneckverbindungselementen and side connecting elements for fixing the rear wall 60, as previously described with reference to FIGS. 10.4, 10.5, 10.6, 12.4, 12.5 and 12.6 explained and shown in these figures. Finally, FIG. 12.12 shows the final state of the assembly of the body.

In the Fign. 12.13 to 12.15 is a similar mounting element 200 "as shown in Figures 12.1 to 12.3, this mounting element 200" can be fitted as shown in Figs. 12.16 and 12.17 shown, to be used on a component 32 'in the form of z.
