Description

The invention relates to a spacer for setting a desired distance between two components.

Spacers for setting a nominal distance between two components, in particular between door frames or window frames and the corresponding inner sides of wall openings and methods for using such spacers are already known from the prior art.

The German utility model DE 2273 U1 discloses two holder elements with wedge-shaped sections connected via a flexible fuse. The holder elements lie with the wedge-shaped sections on each other and can be moved against each other. Depending on the position of the two holder elements to each other, a different height of the spacer can be adjusted via the wedge-shaped sections. The length of the spacer varies with the set height. The wedge-shaped sections of the holder elements have at least partially teeth, which interlock after the joining of the two holder elements and thus avoid slipping out of the holder elements. The fuse ensures that the two holder elements remain connected as a pair. The spacer has the disadvantage that it may, for example, in the alignment of a door frame or a window in a wall opening as a whole fall out when the distance between the door frame or the window and the inside of the wall opening is greater than the height of the spacer.

The international patent application WO 2005/068762 A1 also discloses two holder elements which are wedge-shaped and connected in pairs. The contact surfaces of this spacer, which are in contact with the setting of a nominal distance of two components comprising resilient elements. These are intended to prevent the contact between the spacer and the components from being lost with a slight variation in the distance, ie the gap between the components to be aligned, whereby the spacer could fall down. Once the distance between the components exceeds the height of the spacer at maximum relieved resilient elements, this solution also has the disadvantage that the spacer as a whole can fall out of the gap between the components.

The object of the present invention is to provide a spacer which solves the disadvantages of the prior art.

This object is achieved by a device having the features of the independent claim. The subclaims relate to advantageous developments and variants of the invention.

A spacer according to the invention for setting a desired distance between two components which are connected to the spacer via contact surfaces of the spacer comprises at least two holder elements movable relative to each other. The at least two relatively movable to each other holder elements are captively connected to each other by means of a fuse. The desired distance is adjustable by means of a movement of one of the two holder elements relative to the other, wherein thereby moves one of the contact surfaces relative to one of the components. One of the two holder elements is adapted to be connected to one of the components at least temporarily independently.

When assembling components, components often need to be aligned in multiple degrees of freedom. The components may be, for example, a door frame or a window and the inside of a wall opening to be aligned with each other. During the orientation of the door frame to the inside of the wall opening, it can happen again and again that the gap between the door frame and the inside of the wall opening varies. As a result, the spacer, which is held only by the contact of both contact surfaces with the door frame or with the wall opening in the intermediate space, fall out of the intermediate space. By using the spacers according to the invention, they can advantageously be connected to the door frame at least temporarily independently with a first of the at least two holder elements with the contact surface.

By a separate connection is meant a connection by which the holder element is connected to the component without external forces, such as by wedging in a gap. The compound advantageously prevents the spacer from falling down. The independent connection can also be set up safe to move. By a secure connection is meant a connection which reliably prevents a relative movement between the two connected elements, such as a holder element of a spacer and a door frame. In particular, a relative movement is to be prevented if the at least one second holder element of the spacer is moved relative to the traverse element securely connected to the door frame by manual operation, hitting or tapping in the effective direction of the spacer, ie in the longitudinal direction of the spacer.

The independent connection can advantageously prevent the spacer from slipping out or falling out of the intermediate space between the door frame and the inside of the wall opening. In particular, the spacer can be connected to the door frame even before the onset of the door frame in the wall opening, so that it can not slip during the alignment of the door frame. An independent connection of the spacer with the wall opening is of course just as possible. Thus, falling out of the spacer as a whole and also a repositioning of the spacers in the difficult to reach gap between the door frame and the inside of the wall opening is advantageously avoided. In addition, can be achieved by a suitable selection of the size of the spacer after the onset of the door frame in the wall opening an advantageous coarse alignment of the door frame to the inside of the wall opening. The at least two holder elements are often already mounted on each other before the onset of the door frame in the wall opening to a function-related arrangement.

By a function-related arrangement is meant here that the at least two holder elements are arranged to each other, that the function of the spacer is guaranteed according to its destination. For example, in the case of a spacer with two wedge-shaped holder elements, the holder elements are arranged relative to one another in such a way that the two outer surfaces, which are at the same time the contact surfaces of the spacer, are arranged parallel to one another and the bevels of the wedges lie on one another.

When aligning the door frame in the wall opening, the two holder elements can slip to each other or lose their function-related arrangement, so that the not connected to one of the components holder element can fall down.

By securing, which connects the two holder elements captive, a slipped holder element can not fall off and be easily brought back into the functional arrangement. In addition, the already mounted in the manufacture of the spacer fuse has the advantage that two mating holder elements are connected captive with each other. A selection of two matching holder elements on site can therefore be omitted. In particular, a pairing of two incompatible holder elements can be advantageously avoided.

With captive a connection of the two holder elements is meant, the two holder elements permanently connects together and can advantageously prevent separation of the two parts. The connection is not set up for fixing or freezing the function-related arrangement of the parts to each other, but is only intended to prevent the loss of one of the two holder elements, or to ensure a connection of a compatible pairing.

The fine adjustment of the door frame in the wall opening, so setting a target distance between the door frame and wall opening can now be performed by the relative movement of the second holder element to the first already connected to the door frame holder element. In this case, the second holder element is moved, for example, with its contact surface relative to the wall opening.

The relative movement of the second holder element to the first holder element can be achieved for example by knocking or hitting one end of the second holder element or by a manual actuation or displacement.

The spacers can be made of plastic, wood, or synthetic resin-bonded flat sawdust, also referred to as OSB hereinafter; but in principle they can also be made of any other suitable material such as e.g. Metal to be made. Plastic is the least expensive material and the connection and the two holder elements can be made in one piece by the use of plastic.

In a further embodiment of the invention, at least one holder element comprises at least one wedge-shaped section. Due to the wedge-shaped design of at least one section of at least one holder element, the distance between the components can be reduced or increased by a simple linear relative movement of the holder elements relative to one another along the longitudinal axis of the spacer. Thus, the distance between the components can be easily adjusted to the desired distance. A holder element with wedge-shaped sections or a keeper designed as a keeper element is simple and therefore advantageously inexpensive to manufacture.

In a further embodiment of the invention, both of the at least two holder elements comprise at least one wedge-shaped section. Due to the at least partially wedge-shaped design of both holder elements, the force distribution over the entire wedge-shaped surface can be advantageously distributed to one another by aligning the holder elements with the bevels of the wedge-shaped section. The contact surfaces of the spacer are matched wedge-shaped sections of a holder element parallel to each other. This can advantageously facilitate the alignment of the spacer between the two components, such as a door frame and a wall opening. For components that have no parallel aligned surfaces, the geometry of the contact surfaces of the holder elements can be adapted to the geometry of the component surfaces individually.

In a further embodiment of the invention, the wedge-shaped sections of the holder elements are designed to be self-locking. By a suitable choice of the slope of the wedge-shaped portion and depending on the frictional resistance of the materials used for the holder elements and their surface finish, the spacer may be self-locking. A flat surface allows a continuous adjustment of the nominal distance between the components. Another possibility for increasing the friction or the resistance to slippage may be the formation of the surfaces of the wedge-shaped sections with an interlocking toothing. In this case, the pitch of the wedge-shaped portion may be larger, wherein the adjustment of the distance in solid increments corresponding to the teeth takes place. For example, the wedges may be designed so that the height of the spacer can be adjusted in the range of one to several millimeters.

In a further embodiment of the invention, one of the at least two holder elements has a guide for guiding the other holder element. The relative movement between the first and second holder members is normally triggered by manual operation or tapping or hammering with a hammer or other object on the movable holder member. In order for the two holder elements to move exclusively in the effective direction of the device, that is to say in the longitudinal direction of the holder element, it is advantageous to guide one holder element in the other holder element. This prevents slippage of the two holder elements perpendicular to the direction of action, which can lead to a smaller change in distance and also to slipping out of the movable holder element.

In a further embodiment of the invention, the guide is formed as an elevation of the sides of the contacting surfaces of one of the holder elements. The other holder member is so narrow that it fits between the inner surfaces of the guide. The elevations on the side of the one holder element can thus advantageously prevent a movement of the movable holder element perpendicular to the effective direction and represent a simple and cost-effective embodiment of a guide.

In a further embodiment of the invention, the guide comprises a spring and a groove. The advantage of a tongue-and-groove guide, such as a dovetail guide, is that in addition to guiding the movement of the movable holder element in the effective direction, it also advantageously avoids the slipping or falling out of a holder element. In particular, in spacers, in which a holder element points in the direction of the ground and thus would fall down due to gravity, such as the bottom of a door frame mounted spacers, the falling or falling apart of the two holder elements can be advantageously prevented.

In a further embodiment of the invention, the fuse connects the thin end of the at least one wedge-shaped section on the one holder element to the thick end of the at least one wedge-shaped section on the other holder element. In the case of holder elements having at least one wedge-shaped section, the fuse can be arranged in particular such that it predetermines the mounting of the two holder elements. When connecting the fuse to the thin end of a first holder member having the thick end of a second holder member, the first holder member may be inserted with the thick end ahead in the space between the two components and connected to one of the components. The second holder element, which is fastened with the fuse at the thin end of the first holder element, can now be taken at the thin end and be pushed with this advance also in the space between the two components. Prerequisite is a sufficient length of the fuse.

In a further embodiment of the invention, a slot-shaped recess along the longitudinal axis of the holder element is formed in the surface of a holder element. The recess comprises at least one widening at one end of the recess for receiving at least one head of a connecting means, which is connected to the other holder element. The connecting means comprises in addition to the head and a body which connects to the head. The connecting means may be formed, for example, as a nail or screw. The head of the connecting means is first inserted at the widening of the recess, which is formed larger than the head of the connecting means, and can then be moved along the recess which guides the body. Since the extension of the head is greater than the width of the recess, the Although connecting means are moved along the recess, but are not pulled out perpendicular to the recess. So that the head of the connecting means can move freely even when setting the desired spacing of the two components, the contact surface of the holder element with the recess should have, for example, a groove. The recess may also be formed as a T-slot, so that no interruption of the contact surface, for example by a groove is necessary. By the head of the connecting means is prevented so that the two holder elements can lose their functional arrangement, when held upside down or connected to a component. In other words, the connecting means in the recess connects the two holder elements movably together. The two holder elements are guided to each other, wherein a rotation of the two holder elements to each other about the connecting means is possible. A combination of the connecting means and the recess with a simple guide can fulfill the same function as a tongue and groove guide. However, the production is easier due to the straight surfaces than with a tongue and groove guide. In particular, in the production of holder elements made of plastic, which are poured into molds, a straight guide and a recess for ease of manufacture is advantageous.

In a further advantageous embodiment of the invention, the guide is formed captive. The guide, such as a tongue and groove guide, can be designed so that the two holder elements are not only guided by the guide, but are also connected to each other captive. On the spring, an additional extension may be formed at one end, which is guided in an extension of the groove. After joining the two holder elements, the extension of the groove can be closed by a lid, so that the extension advantageously prevents withdrawal of the one holder element from the other holder element. The guide then assumes the function of securing, whereby the holder elements of the spacer are connected to each other captive. Another alternative would be an elastic thickening of the spring and / or a narrowing of the groove at the joint. The joint is the point at which the one holder element is inserted into the guide of the other holder element. Joining can be done by overcoming the resistance at the elastic constriction, whereby the holder elements are connected to each other captive. To separate the two holder elements, the resistance at the bottleneck can be overcome by actively pulling on the holder elements. The resistance at the bottleneck is designed so that the weight of a holder element is not sufficient to overcome this.

In a further embodiment of the invention, the at least temporarily independent connection between one of the holder elements and one of the components is formed as a non-positive connection. The frictional connection of the holder element can be realized for example by a double-sided adhesive tape. Any other frictional connection, such as magnets or adhesive forces, may be used depending on the nature of the surface or material of the component. A frictional connection can advantageously be easily removed after setting the desired distance and fixing the distance.

In a further embodiment of the invention, the force-locking independent connection comprises a protective film with a projection. The compound can be designed in particular as a double-sided adhesive tape. This is glued with one side on one of the holder elements and includes on the other side a protective film. The protective film may include a projection over the adhesive tape, which allows the user to easily remove the protective film, possibly with gloves, which advantageously simplifies the handling of the spacer.

In a further embodiment of the invention, the independent connection between one of the holder elements and one of the components is designed as a positive connection. The holder element can also be screwed to the component, such as a door frame, or nailed in the case of a Holzturzarge to achieve a positive connection. But there are also positive connections with hole and pin or a groove and a spring conceivable that are merely plugged or other positive connections that will not be carried out here. Furthermore, a combination of non-positive and positive connections is possible in principle.

In a further embodiment of the invention, at least one cross-sectional reduction for separating a part of the holder element is formed on at least one holder element. The cross-sectional reduction can be designed so that the cross section is reduced perpendicular to the effective direction. Depending on the embodiment, the cross-sectional reduction may be formed on the contact surfaces to the components or on the contacting surfaces of the at least two holder elements. Furthermore, the cross-sectional reduction can also extend from the side surfaces of the holder element perpendicular to the effective direction. The At least one cross-sectional reduction can be used to separate at least one holder element after adjusting the distance between the components at the cross-section reduction and thereby shorten. As a result, the length of the spacer can be adapted to the geometry of the components. For example, after aligning a door frame in a wall opening, the sections of the spacer projecting beyond the door frame can be separated at the cross-sectional reductions. The number of cross-sectional reductions depends on the application of the spacers and must not affect the function of the surfaces of the holder elements. Especially with narrow components, the spacer may be beyond alignment after alignment. By being able to shorten the holder elements, the spacers may be made longer than the component and different components and / or spacings may be aligned with a spacer design. The cross-sectional reductions simplify the separation of the protruding portion of the holder element advantageous. Depending on the material of the holder element, the cross-sectional reductions may advantageously be designed in such a way that separation is possible even without tools. It is also conceivable to carry out the toothing of the surfaces in such a way that their cross-sectional reduction allows separation after termination of the adjustment of the distance of the components.

• - Verbinden eines Abstandshalters mit einer der mindestens zwei Komponenten,
• - Einstellen des Sollabstandes zwischen den Komponenten durch Relativbewegung des einen Halterelementes zu dem anderen Halterelement,
• - Abtrennen der überstehenden Bereiche der Halterelemente an den Querschnittsreduzierungen.

A method for setting a desired distance between two components with a spacer comprises the following method steps:

• Connecting a spacer to one of the at least two components,
• Adjusting the nominal distance between the components by relative movement of the one holder element to the other holder element,
• - Separating the protruding portions of the holder elements on the cross-sectional reductions.

The method describes, for example, the installation of a door frame in a wall opening. The spacers may be connected to the door frame before it is inserted into the wall opening or aligned therein, wherein the fuse connects the two holder elements firmly. As a result, the insertion or alignment of the door frame in the wall opening and thereby the assembly process can be advantageously simplified. After completing the alignment of the door frame in the wall opening, so setting the desired distances between the door frame and the wall opening, the protruding portions of the spacer can be advantageously separated. This allows the spacer to remain as a rigid connection between the door frame and the wall opening.

1 shows a section of a wall 1 with a wall opening 2 that is an inside 3 includes, as a component 3 and a door frame 4 as a second component 4 , between which the desired distance to align the door frame 4 in the wall opening 2 should be set to a desired distance. Between the door frame 4 and the inside 3 the wall opening 2 are several spacers according to the invention 5 arranged. The side of the door frame 4 arranged spacers 5 are with the door frame 4 connected and have on the door frame 4 side facing away from any contact with the inside 3 the wall opening 2 , The at the top of the door frame 4 arranged spacers 5 are also with the door frame 4 connected and stand with the door frame 4 opposite side with the inside 3 the wall opening 2 in contact. This is the door frame 4 provisionally so in the wall opening 2 fixed so that it can not fall out. By adjusting the height of the spacers according to the invention 5 can the door frame 4 now in the wall opening 2 be aligned and then the remaining gaps between the door frame 4 and the inside 3 the wall opening 2 be filled with construction foam, for example.

2a shows a spacer according to the invention 5 , the two wedge-shaped holder elements 6 . 7 includes, hereinafter also referred to as wedges 6 . 7 be designated. The holder elements 6 . 7 may also be only partially wedge-shaped. The slope of the wedges 6 . 7 is designed so that this together with the frictional resistance of the surfaces of the wedges 6 . 7 to a self-locking behavior of the spacer 5 can lead. The frictional resistance of the two wedge surfaces depends on the choice of material, the surface and the material combination of the wedge surfaces of the wedges 6 . 7 dependent. The higher the frictional resistance, the steeper the slope of the wedge 6 . 7 be executed and vice versa. The surface may additionally include teeth or other unevenness, which interlock and thus increase the frictional resistance in addition. The teeth also allow adjustment of the spacing in grids, the size of the grids being based on the distance of the teeth and the pitch of the wedges 6 . 7 depends. For example, the wedges 6 . 7 be designed so that the height can be adjusted in the range of one to a few millimeters. The two wedges 6 . 7 are arranged to each other, that after joining the two wedges 6 . 7 to a spacer 5 lying outside surfaces parallel to each other. The movement plane 10 of the two inner surfaces describes by the wedge-shaped geometry compared to the parallel outer sides 8th a slope. The outside surfaces 8th of the two wedges 6 . 7 , which are also referred to below as contact surfaces 8th be designated stand during the establishment of the distance of the door frame 4 to the inside 3 the wall opening 2 with the door frame 4 or the inside 3 the wall opening 2 in contact. One of the wedges 6 includes a tie layer 12 For example, on one side with the wedge 6 is firmly connected and on the other side comprises a layer of adhesive, which allows the wedge 6 with the door frame 4 at least temporarily non-positively connect. The connection layer 12 may for example be a double-sided adhesive tape. But it is also a connecting layer 12 which predominantly comprises adhesive or an alternative bonding layer 12 conceivable. The first wedge 6 and the second wedge 7 are with a fuse 9 captive connected. This has the advantage of always matching wedges 6 . 7 used together, so two wedges 6 . 7 that fit each other in pitch, width, length, and materials. During the preparation phase, ie before inserting the door frame 4 in the wall opening 2 , the spacers can 5 with the connection layer 12 one wedge 6 with the door frame 4 be connected and the other wedge 7 is captive with the first wedge 6 connected and so can not get lost. For fixing the door frame 4 in the wall opening 2 becomes the wedge 7 , which does not match the door frame 4 is connected, against the door frame 4 connected wedge 6 along the plane of motion 10 So along the slope of the wedges 6 . 7 shifted so that the distance of the contact surfaces 8th of the spacer 5 so can be enlarged, up to the contact surface 8th of the movable wedge 7 the inside 3 the wall opening 2 touched. Are all spacers 5 with the door frame 4 and the inside 3 the wall opening 2 In contact, the distances through the spacers can 5 be adjusted so that the door frame 4 in the intended nominal position in the wall opening 2 is fixed. By the with the door frame 4 connected spacers 5 These can not then from the space between the door frame 4 and the inside 3 the wall opening 2 fall if this is greater than the height of the spacer 5 is. Finally, the remaining spaces between door frame 4 and inside 3 the wall opening 2 For example, be foamed with construction foam.

Furthermore recognizable in 2a is a hole in this example 33 trained engagement element, which can serve in particular, the wedge 7 move back, so the total thickness of the arrangement of the two wedges 6 and 7 to reduce. For this purpose, in particular with an angled tool or a hook in the hole 33 intervene and train be exercised. The engagement element 33 does not necessarily have to be formed as a hole or hole, it can be realized in particular as a cam, groove or rib.

2 B shows a sectional view of a spacer according to the invention 5 , On the sides of the one holder element 6 are on the left and right side different embodiments of a guide 11 . 11 ' shown, wherein a spacer 5 normally only one embodiment of a guide on both sides 11 . 11 ' includes. The left side of the 2 B shows a straight guide 11 Easy to make. The straight lead 11 is as an increase in the form of flanks on both sides of a holder element 6 formed, wherein the inner surfaces of the flanks are formed parallel to the side surfaces. The other holder element 7 is narrower than the first holder element 6 trained so that it is between the flanks of the leadership 11 of the first holder element 6 can be inserted. The movable holder element 7 can continue along the effective direction of the wedges 6 . 7 , are moved to adjust the distance. Lateral slipping or twisting can be advantageously prevented by the lateral guide 11. Is the game between the movable holder element 7 and the leadership 11 of the other holder element 6 low and the holder element 7 Adheres to the lateral guide, can after joining the two holder elements 6 . 7 falling out over the friction between the holder element 7 and the leadership 11 be advantageously prevented.

The leadership 11 ' on the right side of the 2 B illustrates a variant of a guide 11, 11 ', which is also known as a dovetail guide. The dovetail guide is a special form of spring-groove guide. In this variant, the groove 24 formed as a recess with an acute angle. The groove 24 So at the lower end it has the greatest depth, which exceeds the height of the groove 24 decreases linearly. The feather 25 the leadership 11 ' is on the other holder element 7 along the side of the holder element 7 formed with a corresponding angle. The feather 25 is at the top at the widest and tapers linearly with the height of the spring 25 , The holder element 7 is with the thin end with the spring 25 in the groove 24 introduced and by moving along the direction of action of the holder elements 6 . 7 together. The dovetail lead 11 ' provides a secure, yet movable, connection of the two holder elements 6 . 7 represents and prevents lateral slippage or rotation of the two holder elements 6 . 7 when setting a distance. In particular, the dovetail guide prevents 11 ' falling out of the holder element 7 with the spring 25 from the holder element 6 with the groove 24 if the spacer 5 with the holder element 7 with feather 25 is held in the effective direction of gravity.

Another variant of the invention is in 3a shown. The one holder element 6 In addition to a straight guide 11 a recess 13 along the longitudinal axis of the holder element 6 on. The recess 13 comprises at the end, which to the thin end of the wedge-shaped holder element 6 shows a broadening 14 , The broadening 14 is designed to take your head 17 a connecting agent 15 can record. The recess 13 is just so wide that the body 16 of the bonding agent 15 along the longitudinal axis of the holder element 6 can be moved, the head 17 of the bonding agent 15 but can not slip out. The connecting means 15 is at the thin end of the other holder element 7 attached. The straight lead 11 in conjunction with that in the recess 13 guided nail 15 has the same function as the dovetail guide described above 11 ' , After joining the holder elements 6 . 7 These are against lateral slipping or twisting by the straight guide 11 protected. The connecting means 15 in the recess 13 ensures a secure but still movable connection of the two holder elements 6 , 7 and thus prevents unintentional falling out of a holder element 7 from the other holder element 6 regardless of the orientation of the spacer 5 in the room. The function-related arrangement of the wedges 6 . 7 each other is so in every position of the spacer 5 ensured. The advantage of this variant is the easier manufacturability and the associated lower production costs.

As in the variants of the invention described above, the two holder elements 6 . 7 with a fuse 9 captive connected. The fuse 9 can be used with plastic spacers 5 for example, be made in one piece. For spacers 5 made of wood, the fuse can 9 a thread 9 , Rope 9 or a soft wire 9 be, each with one end with one of the two holder elements 6 . 7 connected is.

3b represents a variant of the invention, which in a holder element 6 two recesses 13 includes. The recesses 13 are arranged side by side and also each include a widening 14 at one of its ends. The broadening 14 are trained so that they each have a head 17 a connecting agent 15 be able to record. The recess 13 is only so wide that a body 16 of the lanyard 15 can be guided in it, the head 17 but does not fit through. The other holder element 7 comprises two connecting means at the thin end 15 that are arranged so that the body 16 along the recesses 13 can be moved. The in the recesses 13 of a holder element 6 parallel guided body 16 the connecting means 15 have the advantage that in addition to unintentional separation of the holder elements 6 . 7 also a guide against lateral slipping or twisting of the two holder elements 6 . 7 given to each other, giving a guide 11 . 11 ' can be omitted. The broadening 14 can be at the narrow and the thick end of the wedge 6 . 7 be arranged, this also applies to the connecting means 15 in the other holder element 6 . 7 , Depending on the application of the spacer 5 can also be a broadening 14 at the thin end of the one holder element 6 . 7 and a connection means 15 at the thick end of the other holder element 6 . 7 make sense.

3c shows a further variant of an embodiment of the slots 13 , where the recesses 13 bend right-angled at one end. At the perpendicular to the longitudinal axis of the holder element 6 . 7 extending part of the recesses 13 they have a broadening 14 on. The right-angled bend, which may also have a deviating from 90 ° angle, makes it difficult to slip out of one of the holder elements 6 . 7 after attaching the spacer 5 on a component 3 . 4 , The kink in the recess 13 prevents one from tilting the spacer 4 caused slippage of the two holder elements 6 . 7 to each other along the recesses 13 can lead to falling out of a holder element 6, 7. The number and shape of the recesses 13 can be designed almost arbitrarily and, if appropriate form, may be applied to the fuse 9 the two holder elements 6, 7 are omitted.

4a shows a holder element according to the invention 6 . 7 in a sectional view. The holder element 6 includes cross-sectional reductions 18 indicating the thickness of the holder elements 6 . 7 sections to a minimum. For the sake of simplicity of illustration, the fuse 9 and a second holder member connected thereto 6 . 7 not shown. The cross-sectional reductions 18 are shown purely schematically and designed so that they function the surface of the holder element 6 . 7 do not interfere. This is at each of the cross-sectional reductions 18 a separation of the holder element 6 . 7 possible. After adjusting the distance of the two components 3 . 4 is done to each other, the over the components 3 . 4 protruding part of the holder or the elements 6, 7 at the designed as predetermined breaking points cross-sectional reductions 18 be separated. This has the advantage that even very narrow components 3 . 4 with the spacer 5 can be aligned with each other without the at the end of the spacer 5 beyond the component.

4b shows a variant of the cross-sectional reductions 18 , The cross-section reduction 18 is doing by reducing the width of the holder elements 6 . 7 reached. Depending on the application of the spacer 5 You can choose one of the two variants. In addition to the variants shown, other variants and / or combinations of the two shown and / or other variants of the cross-section reduction are certainly also possible 18 conceivable.

5 shows a plan view of the connection layer 12 of the spacer 5 , this being a protective film 19 includes. The protective film 19 protects the adhesive layer of the tie layer 12 until the spacer 5 with a component 3 . 4 , such as a door frame 4 is connected safely. The protective film 19 is opposite to the adhesive layer and the holder element 6 formed longer, so includes a supernatant 20 , The supernatant 20 is set up so that it simply peel off the protective film 19 allows. In particular, the supernatant 20 is designed so that a peeling off the protective film 19 with gloves is possible, what the handling of the spacers 5 advantageously simplified.

Alternative to the connection layer 12 is also a safe connection of a holder element 6 with one of the two components 3 . 4 conceivable with a positive connection. 5 shows exemplarily three holes 21 , shown as an alternative in dashed form, through which the spacer 5 with a nail or a screw on one of the two components 3 . 4 , such as a door frame 4 can be fixed safely. Other positive connections are conceivable, such as rivets or a gearing, in which case also the component 3 . 4 must have a corresponding surface.

A variant of the fuse 9 for the captive connection of the two holder elements 6 . 7 is in Fig. 6a and 6b shown, wherein the holder elements 6 . 7 again as wedges 6 . 7 are formed. 6a shows a detail of a section through the spacer 5 , The leadership 11 ' is as described above as a dovetail guide 11 ' executed and includes at the thin end of the wedge 6 as a local broadening of the spring 25 an additional extension 22 , The extension 22 is only over part of the spring 25 educated. In the groove 24 the other wedge 7 is over the entire length of the groove 24 a recess for the extension 22 educated. After joining the two wedges 6 . 7 becomes the part of the groove 24 in which the extension 22 runs, with a lid 23 locked. This allows the extension 22 no longer out of the groove 24 slip and the two wedges 6 . 7 are connected together in a captive manner. The fuses described above 9 are after the assembly of the lid 23 no longer necessary and can be omitted. The leadership takes over 11 . 11 ' advantageous the function of the fuse 9 ,

7 describes a possible method for setting a desired distance between two components 3 . 4 with a spacer according to the invention 5 of the 2 - 6 ,

In a first process step 30 becomes a spacer 5 with one of the components 3 . 4 connected.

In a second process step 31 becomes the nominal distance between the components 3 . 4 by a relative movement of the one holder element 7 to the other holder element 6 set.

In a third process step 32 become the protruding portions of the holder elements 6 . 7 at the cross-section reductions 18 separated.

The method describes, for example, the installation of a door frame 4 in a wall opening 2 , The spacers 5 can with the door frame 4 be connected before this in the wall opening 2 is aligned, with the fuse 9 the two holder elements 6 . 7 this firmly connects, whereby the assembly process can be advantageously simplified. By the possibility of a reduction of the holder elements 6 . 7 in the holder element 6 . 7 trained cross-sectional reductions 18, after alignment of the door frame 4 in the wall opening 2 the protruding portions of the spacer 5 be advantageously separated so that they do not survive. This allows the spacer 5 between the door frame 4 and the inside 3 the wall opening 2 remain and do not have to align and fix the door frame 4 in the wall opening 2 be removed again.
