Description

The The invention relates to a clamping connection device for the production a first component and a second component bracing each other Clamping and equipped with a clamping device Furniture and a a clamping connection device applying method.

Basically It is known, for example, bicycle components with clamping connection devices with each other connect to. For example, a wing-like clamping arm with the help a pivot shaft pivotally mounted on an axle piece to to tension this in a pulling direction. The axle piece is for example a bicycle hub or the like. Furthermore, it is possible that spindle components in the form of tie rods, for example, by two protruding clamping portions a seat tube are pushed through and with the clamping arm against each other be tense.

The However, mounting such clamping devices is complicated, so that their scope is limited.

It is therefore the object of the present invention, an easy to handle Clamping device and a furniture equipped therewith and to provide a corresponding procedure.

to solution the task is a clamping device with a tie rod part and a pivotally mounted on the Zugankerteil clamping arm for Production of a first component and a second component with each other provided tensioning clamping connection, wherein the clamping arm in a clamping pivot position spans the second component in the direction of the first component, wherein the tie rod tensile fastener for tensile connection with the first component in the manner of a tie rod and in the assembled state with a bearing end in front of the first and the second component protrudes, wherein the clamping arm at an exciting a bearing mount for pivot bearing end of the bearing and a at a pivoting of the clamping arm in the direction of the clamping pivoting position via a Dead center addition to the second component along sliding clamping shoulder and wherein at the exciting end of the tensioning arm is a between the Bearing holder and an outer contour extending slot for the Zugan kerteil is present, which the slot when pivoting the Clamping arm passes through the clamping pivot position, wherein the slot an open end to insertion having the Zugankerteils. The slot is a pivotal slot, so to speak.

to solution The object is also a method in a further independent claim specified. This process is particularly innovative in furniture construction and very beneficial.

One The basic idea of the invention is that the tie rod part and the tensioning arm are separable units. So it's easy, the tie rod part first to anchor in the first component and then the clamping arm on the Tilting anchor part to be set in a pivoting manner. This allows it For example, different configured Zugankerteile ready to make, for example, have different lengths, different configured fasteners and the like. It can be used in each case the same clamping arm. Also at the Clamping arm are possible without further variants, which are to be achieved Clamping connection are optimally adapted. The respective tie rod part can stay the same.

It is understood to be exciting between the first and the second Component also further arranged so to speak with exciting components could be and / or that the two construction parts or parts of a parent component are.

The inventive fastening technique or Clamping technology can be used in many fields, for example, the automotive industry. However, the application is especially in furniture construction, wherein the components are components of a respective piece of furniture, with the clamping device according to the invention, which can be referred to as a clamping clamp, are connectable.

The Clamping device according to the invention has, so to speak, a slotted pivot bearing. To connect and from each other Separating the two components of the clamping device, namely the tie rod part and the clamping arm, no tools are necessary.

Of the Slot runs corresponding to the clamping shoulder, for example substantially parallel. It is understood that the slot also, for example aslant can run to the clamping shoulder. The slot becomes, for example from a support portion carrying the bearing end of the Zugankerteils penetrated.

The outer contour the exciting forms a clamping contour. The clamping shoulder or clamping contour has to clamp the compo le a clamping section and an adjacent, to release the components provided release section.

The slot extends zweckmäßigerwei up to the clamping section. Preferably, the slot has a curve in cross-section, so that it can be called a curved slot.

The Bearing support and the clamping shoulder have a convenient corresponding curvature. It goes without saying that but also different curvatures are easily possible in the bearing and the clamping shoulder. So For example, the bearing support can be exactly spherical, while the Clamping shoulder is eccentric and vice versa.

Though Is it possible, that only a single clamping shoulder is placed next to the slot is. Preferably, however, two clamping shoulder sections are provided, between which runs the slot. You could but also speak of a single tension shoulder, the slotted is.

At least outside the clamping pivot position, z. B. in a release position of the clamping device, in which the clamping connection is canceled, the clamping arm is expediently around a longitudinal axis the Zugankerteils pivotally. Thus, it is possible, the tension arm in a desired Swivel position transverse to the longitudinal axis to swing the Zugankerteiles, for example, where space is. Furthermore, it does not depend on the respective rotational position of Zugankerteils in the first component, for example, due to a screwing not always exactly adjustable.

The The bearing end of the tie rod part has, for example, a cylindrical or part-cylindrical shape, wherein the bearing receptacle corresponding to the bearing end is hollow cylindrical.

Especially however, it is preferred that the bearing end be at its bearing receptacle facing bearing side spherical is, for example, circular spherical or eccentric spherical, and the bearing seat corresponding to the bearing end then also spherical, that is hollow spherical, is. Thus, a kind of ball joint is formed. The bearing receiver forms a joint socket, so to speak. Thus, the clamping arm on the tie rod part on the one hand pivotable to make the clamping connection or again dissolve and further around the longitudinal axis the Zugankerteils rotatable.

It It is understood that the clamping arm and the tie rod part each one-piece or may also be multi-part components. For example, the bearing end of the Zugankerteils is a first component, while a section with the tension fasteners second component, wherein both components are firmly connected are, for example, a glue or screw. The same thing is possible with the tensioning arm, which may also be a multi-component component.

Of the Tensioning arm has expediently in front of a clamping arm base, for example an actuating portion, projecting Fork arms which are the tie rod part, in particular the end of its bearing, forked embrace. When the clamp arm is pivoted to its cocking pivot position, it spreads Bearing end of Zugankerteils the two fork arms away from each other, when both fork arms are flexibly attached to the clamp arm base. But it is also conceivable that only one of the fork arms is flexible, while the other fork arm is relatively stationary, so that only the flexible Fork arm is displaced from the bearing end during pivoting of the clamping arm. The Warehouse end presses the fork arms apart so that bearing receiving areas on the Fork arms, z. B. hollow spherical bearings or the like, to the advantageous spherical Slide bearing side of the bearing end of Zugankerteils along and that against a clamping direction of the clamping device. The Fork arms are pushed aside, so to speak, so that bearing sections of the Bearing support between the bearing side of the tension member and the exciting second component, which has a smaller cross-section exhibit. The spreading of the fork arm begins expediently approximately in the area of the dead center, when the clamping arm, in the clamping pivot position is pivoted.

The resilient property of the fork arms can be due to the material of the clamping arm itself causes, for example, is elastic. It has shown in practice that a plastic material already has this Properties may have. But it is also possible, a fork-like spring insert, which extends into the two fork arms into and gives these resilient properties. It is also possible to have one Two-piece spring to take, with each spring part of the fork arms assigned. When one of the fork arms is stationary while the It has other springy properties, it is also possible only to provide a metal spring on the resilient fork arm. The respective metal spring is preferably encapsulated with plastic.

at the train fasteners are different variants for anchoring possible on the first component, which can also be used in combination with each other.

Thus, the tensile fastening means, for example, a screw thread for screwing into the first component aufwei sen. The screw thread can be a metric thread or a cutting thread, in particular for cutting into wood components. The latter variant is advantageous in furniture construction. At the bearing end of Zugankerteils are expediently a tool holder and / or a suitable for pressing by means of a rotary tool outer contour, for example, a polygon provided. For example, the tool holder is suitable for a screwdriver and positioned at the top of the bearing end.

The Train fasteners can also a tensile projection, such as a flange, arm-like Single projections or the like, transverse to the tension-tensioning direction of the tension-connection device protrude in front of the tie rod part. For example, the Zugvorsprung to support the Zugankerteils on an underside of the first component, the tension arm averted, suitable.

At the pulling projection is expediently a spring means for resiliently supporting on the first component, in particular its underside, provided. The spring means can, for example, a O-ring, a plate spring, an elastic coating on the pulling projection, a spring ring or a spring washer or the like. The Spring means provide a compliance in tension or tension direction the tension connection device. This limits, for example, one Traction or tension acting on the components. Further, a Maßtoleranzausgleich possible with the components to be connected. Also the components themselves can be elastic be, which is the case for example with chipboard.

The Tie rod part has expediently a support projection, which is effective against the clamping direction of the clamping arm. The supporting projection serves for supporting the Zugankerteils on a clamping arm facing the top of the first component. The support projection is in front of the tie rod part transverse to its tensile or longitudinal axis in front. Between the clamping shoulder and the slot of the clamping arm is expediently a recess, for. B. a return for the supporting projection available.

The Clamping shoulder has expediently one in terms of a pivot axis of the pivot bearing passing through the tension member bearing end and the tension arm bearing receiver is formed, eccentric course. The dead center is for example provided on the tension shoulder.

Below the bearing end, which may be configured as a bearing head, is the Zugankerteil designed like a waist. For example, the outer periphery the tie rod part at this area smaller than adjacent Areas of the Zugan kerteils, for example, the bearing end and a train-mounting section, which is in the mounted state in the first component.

Of the Clamping arm preferably has a flat underside for flat contact on the second component. In the cocking pivot position is thus the clamping arm flat on the second component, so he only uses a tool graspable and in the direction of a release pivot position, that is from the Tension swivel position out, is pivotal.

Especially In this variant, it is advantageous if an actuating recess is provided, in which an actuating tool for pivoting the clamping arm out of the clamping pivoting position can be inserted. The actuating recess is conveniently located between the exciting or bearing end of the tensioning arm and an actuating end, that is graspable by an operator.

Of the Tensioning arm has expediently a wedge-shaped Shape and rejuvenated from its exciting to a side facing away from the operating area out. Thus, where the clamping arm is where particularly large clamping forces required are relatively much material present, while the less force-absorbing Operating range, designed as a kind of swing wing can be flat, flat. This is also advantageous from aesthetic Establish, because the tension arm then builds flat. It is understood that instead of one wedge-shaped Shape also a stepped shape of the clamping arm is conceivable.

Of the Clamping arm or the tie rod part can made of metal, plastic, fiber-reinforced plastic or the like exist, with combinations are readily possible.

9 a perspective view of a schematically illustrated tie rod part of a fifth embodiment of a clamping connection device according to the invention.

at the following embodiments are the same or similar components with the same reference numerals and are not explained in detail.

In the 1a - 7 illustrated clamping connection devices 10a . 10a ' . 10a '' . 10a ''' each have a clamping arm 12a attached to a tie rod part 11a . 11b or 11c is pivotally mounted. A tension arm 12d a tension connection device 10d can also be used instead of the tensioner arm 12a each pivoting with tie rods 11a - 11c get connected.

The tension connection devices 10a - 10d serve to connect a first component 13a and a second component 14a For example, furniture panels.

The tie rod part 11a is through an insertion opening 15 put through the two components 13a . 14a interspersed.

The tie rod parts 11a have as tensile fasteners 16a pull flanges 18 acting as pull tabs 17 at the respective bottom 19 of the first component 13a directly or indirectly abut and the tie rod part 11a tensile strength with the first component 13a anchor. In the tension connection device 10a according to 1a - 2c is the pull flange 18 immediately at the bottom 19 of the second component 13a at.

At the tension connection devices 10a ' . 10a '' and 10a ''' according to 3 - 5 however, are between the pull flange 18 and the bottom 19 spring means 20a . 20b and 20c intended. The spring means 20a is formed by an O-ring, for example made of elastic plastic or rubber. The spring means 20b includes one of the tie rod part 11a penetrated plate spring 22 while the spring means 20c one from the tie rod part 11a penetrated spring washer or a spring washer 23 is. It is understood that the combination of several spring means is conceivable, for example, the combination of the O-ring 21 with the diaphragm spring 22 or similar. Alternatively, it would be possible for a total of a pull projection according to the invention to have resilient properties, for example, yielding. In any case, the feathers provide 20a - 20c for being the tie rod 1a Although tensile, but resilient to train with the first component 13a is anchored. This is particularly advantageous when the first component 13a has no elasticity.

A warehouse end 24a of the tie rod part 11a is in the mounted state in front of the first and second component 13a . 14a free before. The end of the warehouse 24a and the train projection 17 are at opposite end portions of Zugankerteils 11a intended. The end of the warehouse 24a is as a jointed head 25 designed. The end of the warehouse 24a forms part of a pivot bearing 26 for pivoting the clamping arm 12a on the tie rod part 11a , The pivot bearing 26a However, it is not permanently connected, but can be opened without tools. Thus, the clamping arm 12a from the tie rod part 11a be removed without a tool and also without a tool on the tie rod part 11a to be assembled.

This is an exciting thing 27 of the tensioning arm 12a a slot 28 with an open end 29 provided, through which the tie rod part 11a in the slot 28 can be introduced. A width of the slot 28 suffices that one the end of the warehouse 24a carrying beam section 30a of the tie rod part 11a free in the slot 28 is movable in its longitudinal direction.

If the tie rod part 11a in the slot 28 is introduced is its exciting 27 in a warehouse 31 exciting 27 of the tensioning arm 12a added. Then there is a camp site 32 forming bottom of the bearing end 24a on the wall of the warehouse 31 at. The camp recording 31 and the exciting 27 , especially the bearing side 32 , are spherical. However, the bearing intake points 31 an eccentricity 33 on. One recognizes this in 2c where one of the exciting 27 more distant area of the bearing receiver 31 a distance too the bearing side 32 having. This warehouse side 32 the end of storage 24 however, it is circular.

The eccentricity 33 is when clamping the clamping arm 12a with the tie rod part 11a advantageous. In this bracing slides a tension shoulder 34 of the tie rod part 11a on the upper, second component 14a along until the tension arm 12a the second component 14a against the first component 13a clamped in a clamping pivot position S. In a release pivot position F, however ( 1a . 2a ) can the tension arm 12a from the tie rod part 11a be removed, so that you have the two components 13a . 14a can solve each other.

The tension shoulder 34 is on an outer contour 35 the exciting 27 intended. The slot 28 runs corresponding to the clamping shoulder 34 that expediently a Ex-centricity 33 and / or a dead center 36 having. The dead center 36 can also be due to the eccentricity 33 be formed, that is, that the outer contour 35 for example in the area of the dead center 36 is circular.

The tension shoulder 34 has two sides of the slot 28 running tension shoulder sections 37 At the free ends of embracing fork arms 38 are arranged. The fork arms 38 stand in front of a clamping arm base 39 of the tensioning arm 12a before and surround the tie rod part 11a the tie rod part 11a at least in the region of the clamping pivot position S bifurcated.

Regarding the clamping arm base 39 have the fork arms 38 an elasticity transverse to the tensile or clamping direction of the clamping device 10a , The fork arms 38 be from the end of the warehouse 24a in the tension swivel position S in the direction of arrows 40 spread apart. Thus, the tension connecting device has 10a a certain elasticity, which, for example, a lack of elasticity and / or dimensional tolerances of the components to be joined 13a . 14a in the clamping direction of the clamping device 10a compensated. For example, there is the clamping arm 12a made of an elastic plastic.

In the embodiments 10a ' - 10a ''' according to 3 . 4 and 5 However, the appropriate for clamping elasticity of the respective clamping device connection by the spring means 20a - 20c be enough. Thus, it is appropriate, for example, the tensioning arm 12a made of a non-elastic material, for. As zinc, die casting or the like to produce.

To support the resilient compliance of the fork arms 38 Metal springs may be appropriate. For example, in the tensioning arm 12d a metal spring 41 embedded, which is advantageously molded with plastic. The metal spring 41 is U-shaped and extends with their free ends in the two fork arms 38 into it. A middle section connecting the two free ends 42 runs through the clamp arm base 39 through, even to the free end of the operation 43 of the tensioning arm 12d , Instead of the continuous metal spring 41 could also be provided a two-piece spring arrangement, for example, a separation between the two springs in the region of the central portion 42 is appropriate.

Except for the inserted metal spring 41 are the clamping arms 12a . 12d similar. They are z. B. both wedge-shaped, with the clamping arms 12a . 12d to the end of the operation 43 both taper in plan view and in side view. Thus created a wing-like structure, wherein the clamping arms 12a . 12d in the area of the pivot bearing 26 are designed to be particularly stable.

At an upper side of the clamping arms 12a . 12d is suitably a corrugation 44 provided so that the clamping arms 12a . 12d can be easily grasped by an operator. However, this is only possible outside of the clamping pivot position S. In the clamping pivot position S is a flat bottom 45 of the tensioning arm 12a . 12d flat on the top of the second component 14a on, so the tension arm 12a . 12d can not be manually intervened.

The tension connection devices 10a - 10d can only be solved with a tool, such as an Allen key (Allen key). Such an Allen key, for example, in a designed as a tool holder actuating recess 46 inserted. The actuating recess 46 is between the camp admission 31 and the end of the operation 43 arranged.

The components 13a . 14a For example, components form a piece of furniture 47 , This is also the case in the 6 and 7 shown first and second components 13b . 14b possible.

Zugankerteile 11b and 11c are with train fasteners 16b . 16c forming screw threads 48b . 48c into the component 13b screwed. The screw thread 48b is a cutting thread, especially a wood thread, the screw thread 48c a metric thread.

So the screw thread 48b . 48c as little as possible through the clamping connection between the two components 13b . 14b are mechanically stressed as little as possible, are in the tie rod parts 11b and 11c supporting projections 49 in the form of supporting flanges 50 provided, itself on top of the first component 13b support. For the support flanges 50 is next to the slot 28 a recess 51 intended.

Alternatively to the previously described ball joint concept of the pivot bearing 26 is also a cylindrical bearing inventively conceivable. From a tension connection device 10a is only the tie rod part 11e shown in the style of Zugankerteils 11a as a tensile fastener 16a a pull flange 18 or Zugvorsprung 17 having. Alternatively, screw thread or the like would be possible as Zugbefestigungsmittel as in the above embodiments.

On a support section 30e of the tie rod part 11e sits a cylindrical bearing end 24e in that in a corresponding, not shown also hollow cylindrical, that is hollow cylindrical bearing receptacle 31 a clamping arm, not shown, can be suspended. This tensioning arm, according to the inventive concept, also needs a slot which extends from the tie rod part 11e is passed through when pivoting in the respective clamping pivot position S.

The carrier sections 30a . 30e are waisted, that is, they have a smaller outer circumference than the adjacent components, namely the bearing ends 24a . 24e as well as plug-in sections 52 in the assembled state of the tension connection devices 10a . 10e at least partially in the respective first component 13a . 14a stuck.
