Description

The invention relates to a quick release for connecting two, e.g. plate-shaped, components. Such a quick release has a nut body, in which an at least partially provided with an internal thread first opening, which has a longitudinal axis, is provided, and a partially screwed into the nut body threaded bolt with an external thread.

A quick release for connecting plate-shaped components is from the DE 20 2010 016 923 U1 known. In this quick release, a threaded pin is provided with an internal thread and can be screwed into a receiving unit. In the direction of the longitudinal axis of the threaded pin, ie in the z-direction, a large stroke can be realized, for example, to compensate for tolerances or to compress a seal. For this purpose, the threaded pin must be screwed in by several turns, depending on the pitch of its thread, which is time consuming when mounting multiple quick-release buckles.

It is therefore an object of the present invention to provide a closure system of the type mentioned above, which is quick to operate even with a large stroke.

This object is achieved with a quick release, in which the threaded bolt can be first introduced with a large stroke in the nut body, without the male thread of the threaded bolt and the internal thread mesh. According to the invention, for this purpose, the first opening has a first inner threaded portion and a second inner threaded portion, which is arranged axially offset to the first internally threaded portion along the longitudinal axis of the first opening and circumferentially offset diagonally. In addition, according to the invention, a further opening is formed in the nut body whose inner diameter is equal to or greater than the outer diameter of the screwed into the nut body portion of the threaded bolt and which extends obliquely to the first opening and this intersects. This makes it possible that the threaded bolt is first inserted through the further opening in the nut body without its external thread with the female threaded sections engages. For this, the threaded bolt does not have to be screwed in, so that it can be inserted quickly even at a great distance. By pivoting the threaded bolt, however, it is possible to bring the outer thread with the female threaded portions in engagement. In other words, the threaded bolt is automatically pivoted after insertion of the threaded bolt in the further opening by rotation within the first opening, so that the threaded bolt can then be screwed by further rotation within the first opening with the nut body.

The further opening preferably extends from the region of the nut body opposite the first internally threaded portion to the region of the nut body opposite the second internally threaded portion. In other words, the further opening is aligned so that it is guided past the two internal thread sections. For this purpose, the longitudinal axis of the further opening with respect to the longitudinal axis of the first opening by 3 ° to 30 °, in particular by 15 ° to 15 °, more preferably by about 10 °, be inclined. The longitudinal axis of the further opening intersects the longitudinal axis of the first opening, for example, at a point which lies in a range between 35% and 65% of the axial length of the first opening, in particular approximately in the middle of the first opening.

In addition, the quick release may have a cage in which the nut body is at least partially received and guided. In particular, the nut body in the cage may be transverse to the longitudinal axis of the first opening, i. in x-y direction, slidably guided to compensate for manufacturing and assembly tolerances.

For this purpose, the nut body has a collar with a non-rotationally symmetrical outer contour, which is guided in a receptacle of the cage with a non-rotationally symmetrical inner contour with a clearance fit. For example, the inner and outer contours rounded rounded, in particular rounded square formed.

Additionally or alternatively, the inner and outer contours may have concave or convex side surfaces. In particular, an embodiment with two opposite concave side surfaces of the collar and corresponding convex mating surfaces of the receptacle of the cage has the advantage that the openings for attachment of the cage further towards each other, i. can be set inside, or can be larger at the same distance. In addition, this embodiment is advantageous in terms of the introduction of force in the support of the torque occurring when screwing the threaded bolt, since the forces are introduced approximately at right angles in the respective area.

Preferably, the collar in the receptacle in a plane transverse to the longitudinal axis of the first opening is limitedly displaceable. Alternatively or additionally, the collar in the receptacle in a plane transverse to the longitudinal axis of the first opening can be limitedly rotatable. A limited shift or limited rotation is a movement to compensate for tolerances, for example that the nut body is freely movable in the cage. Rather, the relative movements are limited to small movements until the collar of the nut body in the receptacle of the cage abuts so that further movement is prevented. Thus, it is for example possible that the nut body is supported in the direction of rotation in the cage when the threaded bolt is screwed into the nut body.

In order to fix the cage to one of the components which are to be connected to each other by means of the quick-release fastener, the cage has openings or other suitable fastening means, for example.

The cage may comprise a cage base in which the receptacle is formed, and a cage upper connectable to the cage base secures the nut body in the cage. In particular, the nut body is securely retained in the cage so that the cage and nut body can be secured as a common assembly to one of the components to be joined.

The threaded bolt is provided in a conventional manner with a head having a relation to the external thread radially projecting bearing surface. In this way, the threaded bolt can be supported on one of the components to be joined together. The contact surface of the threaded bolt can also be enlarged by a washer.

The quick release may additionally have an elastically deformable element. Such an elastically deformable element may be a seal and / or a spring. The elastically deformable element may be provided between the bearing surface of the threaded bolt and the nut body, for example as a spring washer, which is supported on the bearing surface of the threaded bolt. If the elastically deformable element is a seal, this can be arranged, for example, between the two components to be connected to each other.

The invention also relates to a method for producing a connection between two plate-shaped components, in particular using a quick-release closure of the abovementioned type. Here, it is provided that the threaded bolt is first inserted substantially coaxially with the longitudinal axis of the further opening and inserted into the further opening, is then pivoted within the nut body such that the threaded bolt is aligned substantially coaxially with the longitudinal axis of the first opening, and finally the external thread of the threaded bolt is screwed to the female threaded portions of the nut body.

Regardless of these process steps, the invention also relates to a nut body having an orthogonal bore, which has two partial threaded portions, which are arranged in the z-direction diagonally in the bore to each other. In addition, a further bore is provided in the nut body with a diameter which is equal to or greater than the thread diameter of a screw plug. The nut body preferably has an outer geometry which, in interaction with a cage, permits a lateral movement in the x-y direction and at the same time, when a torque is applied, supports it on the wall of the cage. The execution of the cage can be one or two parts.

• 6b in a partially sectioned view, a second step for connecting two components by means of a quick release according to the invention; and
• 6c in a partially sectioned view, a third step for connecting two components by means of a quick release according to the invention.

One in the 6a to 6c During the assembly shown quick release has a threaded bolt 1 , a nut body 2 as well as an optional cage 3 on, for example, two plate-shaped components A and B to connect with each other. These are the two components A and B With Through openings provided by the threaded bolt 1 can be carried out.

In the in the 6a to 6c example shown is on the component A on the component B facing side an optional compressible seal 4 intended. Next is the nut body 2 by means of a cage 3 in the example shown on the component A attached. Notwithstanding the illustrated rivet connection, the cage can also be in another suitable manner to the component A be set.

The nut body 2 is in the 1 to 5b shown in more detail. The nut body 2 is an example cylindrical member with a radially projecting collar 5 at one end (top in 1 ). Like from the 3 . 5a and 5b is apparent, is the collar 5 designed substantially square with rounded corners, wherein two opposing side walls have concave recesses.

In the nut body 2 is a first opening 6 formed, which in the illustrated embodiment has a through hole with a longitudinal axis I is. A second opening 7 with a longitudinal axis II runs obliquely to the first opening 6 in the nut body 2 so that the longitudinal axes I and II for example, cut approximately in the middle of the nut body. In the embodiment shown, the longitudinal axis II the second opening 7 about 10 ° to the longitudinal axis I the first opening 6 inclined, which is orthogonal to that through the collar 5 defined level runs.

On the inside of the first opening 6 is a first female thread section 8a on the in 1 formed on the right upper side and a second inner threaded portion 8b is on the in 1 formed on the left lower side. The two internal thread sections 8a . 8b do not extend over the full circumference of the first opening 6 and not over the full axial length of the first opening 6 , Rather, the two female threaded sections 8a . 8b at opposite axial ends of the nut body 2 formed on each other in the circumferential direction diametrically opposite sides.

The second opening 7 runs from the first female threaded portion 8a opposite region also the second female threaded portion 8b opposite region of the nut body 2 , The second opening 7 has an inner diameter equal to or greater than the outer diameter of the threaded bolt 1 in the area of its external thread 9 is. In other words, the threaded bolt can be 1 in the second opening 7 plug in when the threaded bolt 1 coaxial to the longitudinal axis II is aligned. The inner diameter of the first opening 6 as well as the internal thread sections 8a . 8b on the other hand are so on the threaded bolt 1 or its external thread 9 adjusted that the external thread 9 in the female thread sections 8a . 8b engages when the threaded bolt 1 coaxial to the longitudinal axis I is aligned.

The quick release shown in the figures also has the cage 3 on top of a cage bottom 3a and an optional lid-like cage shell 3b can exist. The cage base 3a is with a recording 10 provided, the inner contour of the outer contour of the collar 5 is adjusted so that this with game in the recording 10 is guided. As in particular from the top view in the 5a and 5b it can be seen, the collar can 5 within the recording 10 both in the plane transverse to the longitudinal axis I be moved limited as well as be rotated limited in this level. If the outer contour of the collar 5 However, on the inner contour of the recording 10 is present, as in 5b is shown, the nut body 2 by means of the collar 5 rotatably in the cage 3 supported. This thus causes a radial clearance and a simultaneous support of the torque when screwing a threaded bolt 1 in the nut body 2 ,

The cage shell 3b , with an example round through hole for receiving the threaded bolt 1 may be provided after insertion of the nut body 2 into the cage bottom 3a mounted and with the cage bottom 3a be connected to the nut body 2 loses safely in the cage 3 to keep. In the illustrated embodiment, the cage shell 3b and the cage base 3a each provided with two lateral passage openings to the cage 3 like in the 6a to 6c shown on the component A to fix.

The connection of the two components A and B with each other by means of the quick release according to the invention takes place as in the 6a to 6c represented in essentially three steps:

First, the two components A and B positioned relative to each other so that their passage openings overlap each other. The nut body 2 is by means of a cage 3 attached to one of the two components, leaving the threaded bolt 1 through the passage openings in the two components A and B in the nut body 2 can be inserted. For this purpose, the threaded bolt 1 initially approximately coaxial to the longitudinal axis II the second opening 7 aligned. As a result, the insertion of the threaded bolt 1 not by the intervention of the external gain of 9 in the two female threaded sections 8a . 8b with special needs. This allows the threaded bolt 1 quickly so far into the nut body 2 until the (screw) head of the threaded bolt 1 with its flange-wide support surface 11 on the component B or an optionally provided washer twelve is applied.

In this in 6b shown state of the threaded bolt 1 then by the one-sided support on the component B or the washer twelve by further pressure on the threaded bolt 1 from the to the longitudinal axis II parallel position in one to the longitudinal axis I pivoted parallel position, ie in 6b pivoted counterclockwise. As a result, the internal thread sections come 8a . 8b with the external thread 9 of the threaded bolt 1 engaged.

This is in 6c shown. The threaded bolt 1 can then continue into the nut body 2 be screwed, wherein the internal thread sections 8a . 8b with the external thread 9 of the threaded bolt 1 stay engaged. As a result, for example, the optional between the two components A and B provided seal 4 be compressed.

By the oblique insertion of the threaded bolt 1 or other suitable screw plug without engagement of the thread, any stroke can be performed in a fast time until the elements to be connected are in contact with each other. When placing the screw head creates a tilting moment, so that the screw thread is pressed into the nut thread. The threaded body can adapt its position to the tolerances by lateral deflection in the xy direction. After the intervention of the two threads, another stroke can be achieved by a few turns, eg to compress the seal 4 or to tension a spring.

The quick release according to the invention is thus to be actuated quickly, can realize a large stroke in the z-direction, in order, e.g. To compensate for tolerances or to compress a seal, and can also compensate for manufacturing and assembly tolerances in the x-y direction.
