Description

The present invention relates to a guide profile for a pull-out lock for a plurality of drawers arranged one above the other in a body and slidable parallel to one another in a pull-out direction, according to the preamble of claim 1.

The invention also relates to a pull-out lock as well as a piece of furniture and a method for equipping a guide profile.

A generic guide profile for a pull-out lock for several drawers arranged one above the other in a body and slidable parallel to one another in a pull-out direction is known, for example, from DE 195 47 049 C2 or the DE 20 2015 106 825 U1 known.

Such pull-out locks are used to enable a plurality of drawers arranged one above the other to be opened simultaneously from a body.

The guide profiles of such pull-out locks, which are essentially C-shaped in cross section, are used to accommodate inserts for spacing control elements for the drawers as well as receiving parts on which control elements are fixed and locking slides with control stops arranged on them, which are accommodated in the guide profile in such a way that only a drawer can be pulled out of the body and at the same time prevents another drawer from being pulled out.

Such pull-out locks and guide profiles have proven themselves.

The object of the present invention is to further develop a guide profile for a pull-out lock of the generic type such that the assembly of the components to be accommodated in the guide profile is further simplified.

This problem is solved by a guide profile with the features of claim 1.

The object is also achieved by a pull-out lock with the features of claim 7, by a piece of furniture with the features of claim 11 and by a method with the features of claim 12.

The guide profile according to the invention for a pull-out lock for several drawers arranged one above the other in a body and displaceable parallel to one another in a pull-out direction has a base surface and bent legs extending on both sides transversely to a longitudinal axis of the guide profile.

At least one of the legs of the guide profile has at least one mounting recess for mounting at least one of the components that can be slidably guided in the guide profile.

In addition to the known possibility of inserting the components that can be slidably guided in the guide profile, such a mounting recess also enables a lateral installation of such a component through the at least one mounting recess from an open front end.

The advantage of such a mounting recess is primarily the reduction in mounting time.

Advantageous variants of the invention are the subject matter of the dependent claims.

According to an advantageous embodiment variant, both legs of the guide profile have at least one mounting recess.

This enables components that can be guided in a displaceable manner in the guide profile to be fed in from a further direction.

The assembly recesses in both legs of the guide profile are preferably arranged opposite one another viewed transversely to the longitudinal axis of the guide profile and thus also enable such a component to be inserted at the front into the slot widened by the assembly recesses between the end edges of the legs.

According to a preferred embodiment variant, the legs of the guide profile have a U-shaped bent adjoining the base surface first section and a planar second section extending from the first section.

According to a further advantageous embodiment variant, a web attachment that is bent over relative to the plane of the base surface protrudes into the mounting recess and thus enables exact positioning of the component to be inserted into the guide profile.

According to a preferred development, the web attachment is formed by the curved first section.

The pull-out lock according to the invention for several drawers arranged one above the other in a body and slidable parallel to one another in a pull-out direction has a guide profile, several inserts guided in the guide profile so as to be slidable along a longitudinal axis of the guide profile, and an actuating element for each drawer, which can be rotated about a direction relative to the pull-out direction and to the longitudinal axis of the Guide profile vertical pivot axis is arranged by pulling out the drawer in the pull-out direction by a pivot angle pivotable on a slidably guided in the guide profile receiving part.

The pull-out lock also has, for each adjusting element, a locking slide guided in the guide profile so as to be displaceable along a longitudinal axis of the guide profile and having an adjusting stop protruding from the guide profile, against which the adjusting element rests.

The locking slide can be displaced by pivoting an actuating element assigned to it.

A displacement of one of the blocking slides in the guide profile blocks a displacement of the other blocking slides.

The guide profile itself is designed as described above.

In an advantageous embodiment variant of the pull-out lock according to the invention, the length of at least one of the receiving parts is less than the length of the at least one mounting recess.

This enables the mounting parts to be mounted through the mounting recess in one or both of the legs of the guide profile.

In a further preferred embodiment variant, the length of at least one of the locking slides is less than the length of the at least one mounting recess.

This also allows the locking slide to be installed via the installation recess.

According to a further preferred embodiment, the length of at least one of the inserts is greater than the length of the at least one assembly recess, this insert being insertable into the guide profile through an open end of the guide profile.

This makes it possible for such an insert to block the assembly cutout after it has been fitted in the guide profile and thus prevent a component which can be fitted via the assembly cutout from sliding out unintentionally.

The piece of furniture according to the invention with a plurality of drawers arranged one above the other in a body and at least one pull-out lock to prevent a plurality of drawers being pulled out at the same time is characterized by a pull-out lock as described above.

In the method according to the invention for equipping a guide profile, the components that can be slidably guided in the guide profile are inserted into the guide profile simultaneously by inserting them into the front open end of the guide profile and by inserting them into the assembly recess on at least one of the legs of the guide profile.

Plan views of the in figure 2 shown embodiment variant of the guide profile in the course of an assembly process of displaceably guidable components in the guide profile.

In the following description of the figures, terms such as top, bottom, left, right, front, back, etc. refer exclusively to the exemplary representation and position of the guide profile, the pull-out lock, body, drawer and the like selected in the respective figures. These terms are not to be understood as limiting, i.e. these references can change due to different working positions or the mirror-symmetrical design or the like.

The figure 1 shows a pull-out lock 30 known from the prior art, installed in a body 2, for example a piece of furniture, with several drawers 5, here three arranged one above the other, which can be pulled out and pushed in from the body 2 in a pull-out direction x, and the basic structure of which shows the structure the pull-out lock 3 according to the invention corresponds.

The pull-out lock 30 is attached here to a body wall 21 of the body 2 and serves to prevent more than one drawer 5 from being pulled out at the same time.

For this purpose, a control pin 52 is arranged in a manner known per se on a side wall 52 of the drawer 5, which is in engagement with an adjusting slot 61 of an adjusting element 6 when the drawer 5 is in the closed position and when the drawer 5 is opened, as is shown by the uppermost of the three drawers 5 in figure 1 is shown, when the drawer 5 moves in the pull-out direction x, the actuating element 6 pivots about a pivot angle α perpendicular to the pull-out direction x and to a longitudinal axis L of the guide profile, the actuating element 6 and thus releases the control pin 52.

The actuating element 6 is rotatably mounted on a pivot bearing 82 of a receiving part 8 . The receiving part 8 is guided in the guide profile 4 in a displaceable manner. In the guide profile 40 there is also a locking slide for each actuating element 6 along a longitudinal axis L of the guide profile 40 7 with an adjusting stop 72 protruding from the guide profile 40, against which the adjusting element 6 rests.

Furthermore, in the guide profile 40 there are a plurality of inserts 9 which are guided so as to be displaceable in the guide profile 40 along the longitudinal axis L of the guide profile 40 .

The displaceable components fill the entire available length of the guide profile 40 except for a free adjusting section, which allows one of the adjusting elements 6 to be rotated by rotating through the angle α into an open position and thereby the locking slide 7 assigned to it by one to the free corresponding distance.

If one of the adjusting elements 6 is in the open position, the entire available profile length of the guide profile 40 is exhausted, so that a further adjusting element 6 is prevented from rotating and thus a further drawer 5 is prevented from being pulled out.

To assemble the guide profile 40 with the components that are slidably guided in the guide profile 40, the guide profile 40 is open on at least one of its front ends, so that the individual components can be pushed into the guide profile 40 axially, i.e. in the direction of the longitudinal axis of the guide profile 40.

In order to be able to accelerate this assembly process, the guide profile 4, 4' according to the invention is installed in the pull-out lock 3 according to the invention.

The guide profile 4, 4 'has, as in the Figures 2 to 4 is shown, a base surface 41 and from this transverse to a longitudinal axis L of the guide profile 4, 4 'on both sides extending bent legs 42, 43, which together with the base surface 41 form an approximately c-shaped cross section.

At the in figure 2 shown first embodiment variant is provided in one of the legs 42, 43, here the leg 43, of the guide profile 4, a mounting recess 44 for mounting at least one of the slidably guided in the guide profile 4 components.

The mounting recess 44 can be produced by cutting out a portion of the leg 42, 43.

At the in figure 3 In the second embodiment variant shown, both legs 42, 43 of the guide profile 4' have such a mounting recess 44'.

It is also conceivable, depending on the length of the guide profile 4, 4', to form a plurality of such mounting recesses 44, 44' along the guide profile 4, 4'.

While at the in figure 2 A web attachment 45 which is bent relative to the plane of the base surface 41 and which protrudes into the mounting recess 44 and ends at an angle of approximately 90° to the base 41 is shown in the embodiment shown in FIG figure 3 illustrated embodiment of the web attachment 45 'by a curved first portion 421, 431 of the legs 42, 43 is formed.

This means that the front edge of the web attachment 45' is perpendicular to the plane of the base 41 here.

At the in figure 2 The embodiment variant shown is preferably formed parallel to the plane of the base surface 41, the front edge of the web attachment 45.

As further in the in figure 3 shown variant embodiment can be seen, the mounting recesses 44 'are arranged transversely to the longitudinal axis of the guide profile 4' opposite.

This has the advantage that components to be inserted into the guide profile 4' can be moved perpendicularly to the base surface 41 in a direction y into the guide profile 4'.

How further in the Figures 2 and 3 shown, the guide profiles 4, 4′ each have an open end 46, via which components that can be slidably guided in the guide profile 4, 4′ are pushed in at the end in direction z, which points in the direction of the longitudinal axis L of the guide profile 4, 4′ can.

A projection 47 is provided in the region of the opposite end 48 of the guide profile 4, 4', which protrudes into the displacement path of the guide profile 4, 4' and thus forms an end or limit stop, beyond which it can be displaced in the guide profile 4, 4' guidable components cannot be pushed out.

The Figures 4a to 4h show a schematic sequence for filling such a guide profile 4 with components that can be slidably guided in the guide profile 4, 4'.

Figure 4a shows the guide profile 4 accordingly figure 2 4 components that can be moved in the guide profile before installation.

Figure 4b shows the assembly of a first insert 9, which is inserted through the open end 46 at the front end of the guide profile 4 and pushed into the guide profile 4 in direction z.

Figure 4c shows the insert 9 accommodated in the guide profile 4.

Figure 4d shows a receiving part 8 placed laterally next to the mounting recess 44 and a locking slide 7.

The length c of the receiving part 8 is smaller here than the length b of the mounting recess 44 and can thus be introduced into the guide profile 4 in a simple manner via the mounting recess 44 .

The length d of the locking slide 7 is also smaller than the length b of the mounting recess 44, so that this locking slide 7 can also be easily inserted into the guide profile 4 via the mounting recess 44.

In principle, both components can also be pushed in via the open end 46 of the guide profile 4 .

At the in Figure 4d In the embodiment variants of the receiving part 8 and the locking slide 7 shown, the sum of the lengths c and d is even smaller than the length b of the assembly recess 44, so that the two components can also be pushed into the guide profile 4 at the same time via the assembly recess 44, thereby reducing the assembly time can be shortened further.

The receiving part 8 and the locking slide 7 are preferably in a direction E, shown in the figures 2 and 4d , pushed into the mounting recess. The direction E is an inclined direction of insertion rotated by an acute angle β about an imaginary axis of rotation parallel to the direction z.

This angle β is due to the in figure 2 shown embodiment variant in the Y-direction relatively flat ridge extension 45 can be made slightly smaller than in the figure 3 shown embodiment with the web extension 45' built higher in the Y-direction, so that the preferred insertion directions E can deviate from one another in the different embodiment variants.

Figure 4e shows the position of the locking slide 7 and the receiving part 8 when pushed into the guide profile 4 state.

Figure 4f shows the end position of the receiving part 8 and the locking slide 7 after the two components have been moved in the direction of the longitudinal axis L of the guide profile 4.

Figure 4g shows a further insert 9 in front of the open end 46 of the guide profile 4, which is to be pushed into the guide profile 4 via the open end 46 and in the pushed-in end position, as in FIG Figure 4h shown, the mounting recess 44 closes over its entire length b.

To equip the guide profile 4, 4', the components that can be slidably guided in the guide profile 4, 4' are simultaneously inserted into the guide profile 4, 4' by inserting them both into the front open end 46 of the guide profile 4, 4' and into the assembly recess 44, 44' on at least one of the legs 42, 43 of the guide profile 4, 4', as a result of which the time required for assembly can be significantly reduced.

For example, an insert 9 and at the same time a receiving part 8 and a locking slide 7 can be inserted via the mounting recess 44, 44' into the guide profile 4, 4' via the open end 46 of the guide profile 4, 4'.

The different insertion directions also allow the components to be brought in easily at the same time, even with automatic assembly.

How in particular Figure 4d can be seen, the locking slide 7 is different from that named as prior art DE 20 2015 106 825 U1 designed as a separate component that can be inserted into the guide profile 4, with a carriage 71 and an adjusting stop 72 fastened or formed thereon, which serves to abut the adjusting element 6, as is also the case in figure 1 is shown as an example.

The receiving part 8 also consists here of a carriage 81 with a pivot bearing 82 fastened or formed thereon, to which the actuating element 6 can be fastened, in particular clipped on.

Depending on the orientation of the actuating element, the sequence of the locking slide 7 and the receiving part 8 in the guide profile can also be reversed.
