PANEL FIXING DEVICE

FIELD OF THE INVENTION

5 The present invention develops a fixing device, especially applied to vehicle doors where a fixed distance must be maintained between the panel or lining and the plate or sheet of the vehicle, incorporating a nut or clip part, a bushing part and a 10 part of Have with the particularity, among others, that said elements of the device have a pre-assembled position, allowing the installation of the device quickly from said position, enabling a fixed part and a removable part that allows the reuse Comfortable device after disassembly.

BACKGROUND

There are many situations where fixing between a support or structure and a lining or panel must be ensured, maintaining a fixed distance between them. This is the case in the automobile industry, for example, in fixing the lining to the chassis of the vehicle door. In these contexts, the conventional fixing means, when they were built, could cause the panel to collapse too close to the chassis. The required requirements represent a tight fixing, easy installation and without tools, allowing in case of disassembly this is easy and the piece does not deteriorate forcing its replacement.

European patent EP0921323 develops a device to deal with this problem of attaching a support to a

plate element in which an intermediate area in the form of a neck is provided that incorporates several retention elements, while on the other hand the coupling piece incorporates ratchet elements antagonistic to the previous ones with which it cooperates to produce a tolerance compensation in the distance between said retaining elements along said axis.

The patent EP0964170 for its part develops a device analogous to the previous one in which the inventive objective pursued lies in obtaining a pre-assembled position between the insert and a bushing that can be hermetically approached therein in the vehicle plate, installation that Finally, it must be completed by adding a joint element to the cladding.

EP1324898 proposes a joint element with tight extraction and insertion forces that have a service position with elastic-locked crimping elements and a use or final position. The joint element can be removed whole for reuse by applying a sufficient extractive force that allows the separation of the shaft or Have from the group of lower parts, which loosen the flare of said lower part or support, while a cap embedded in the end de la Have pulls out the support part and the joint element assembly.

Some known devices allow a quick installation starting from a service position of the parts that make up the fixing device so that the operator sees his work facilitated by taking the device

preassembled and install it in a simple operation, pressing against the body. However, even with its advantages, in the prior art the union of the device with the body and the panel is difficult to reuse, usually because its extraction makes useless part of the device, or this is completely removed, without allowing the possibility of disassembly partial, where elements of the device are already fixed, while the reuse of the device is allowed, separating the lining and allowing its subsequent union.

Therefore, the main objective of the present invention is a device for fixing to a support or sheet element, the chassis of a vehicle, of a cladding element, the panel of for example the door of a vehicle, which has a pre position mounted and service.

Another objective of the invention is that the installation of said device be of the fast type from said pre-assembled and service position.

Another of the objectives of the invention is that the installation of the piece fix the fixed part of it that remains in that operation embedded in the chassis, so that the clip can also be partially disassembled, only removing its mobile part or Have to fix the siding.

Yet another objective of the invention is that said device be sealed once installed, incorporating

installation.

These and other advantages of the present invention will be more apparent throughout the description thereof that follows.

DETAILED EXPLANATION OF THE INVENTION

The present invention consists of a fixing device, of the type that makes a union between a structure or support and a lining or panel element, for example in vehicle doors, where a separation distance must be maintained between the panel and the vehicle plate, formed by a nut-clip part (1), a bushing part (2) and a Have part (3).

The nut-clip part is formed by a hollow cylinder (16) that at one end has a surface (11), as a wall, that extends perimetrically, and at the other end has notches or recesses that enable both fingers (12) that have elastic capacity to open and fit into locking elements arranged in the part of Have (3).

The surface of said tubular or cylindrical body (16) has approximately emptyings or windows (13)

5

of a "U" that make up a one or flexion flange and

guide (15). The interior perimeter of said window (13)

incorporates a hook (14) oriented laterally, that is in a tangential direction to said cylinder (16), said

hooks (14) aimed at locking and elements of

retention provided in the bushing part (2).

 At the end of these

 flexion tabs (15) are

 present

 Layers or fingers (18), as you can

 appreciate

 easily in the section of figure 5,

 directed

 to the center of said nut-clip (1) • This

construction mainly allows that when the bushing (2) is inserted in said clip-nut (1) to its final application position, by the mechanical thrust against the fingers (18) the bending tabs (15) open outwards of the nut-clip (1) producing both the lock between said nut-clip (1) and said bushing (2) and the fixation of this assembly in the chassis of the body of the vehicle, since said flexion tabs (15) are now a stop that prevents extraction.

On the inside, said flexion tabs (15) can incorporate reinforcements (19), as shown in Figure 6.

The bushing part (2) is also a hollow cylinder and incorporates in the outer surface of said cylinder (25) two guides (22) and at least two steps (23 and 23 ') arranged laterally therein and configured to offer at least two locking, service and end positions, with the antagonist elements provided in the clip-nut part, the hooks (14).

It can also have a reinforcing rib (24), which acts as a stop for lowering the bushing, in the form of a ring that consolidates said guides (22) and said locking steps (23, 23 ') - Lowerly it can have a lowered perimeter ( 27) to improve the elastic response of this part of the piece. In the preferred embodiment shown in the graphics, windows (26) have been arranged.

The part of Have (3) has an axis or stud (31) in which in the vicinity of whose end (32) it has at least two annular valleys (36, 36 ') for crimping the flexible fingers (12) arranged at the end of said clip nut (1).

At the other end of said Have (3) the cover or base thereof (34) and at a certain distance from it a support surface (33) are located.

The axis (31) of the part of Have (3) has at least from the base (34) a general conical shape, being narrower in section at the tip (32) than in the area near the flat surface ( 33). Elio represents a progressive inclination of said axis (31) that facilitates its insertion in the other parts (1 and 2) of the device of the invention.

Said axis (31) also has different bulges that delimit valleys or annular depressions. Specifically, two of these depressions or annular valleys (36, 36 ') are enabled in the area of the tip (32) of the shaft and two more (37 and 37') at a distance from the previous ones. These valleys

5

allow flexible locking of other elements

antagonists provided in the other parts (1 and 2) of the device as explained below, in service position and in application position.

The invention provides for the use of gaskets

sealing, for example the sealing gasket (17) of the clip-nut (1) which has suitable notches for its fit, these joints being made of flexible material.

The part of Have (3) incorporates, in a known way, in its upper surface (34) a mechanism of tolerance or centering of the piece consisting of an outer steering wheel attached to the central axis by flexible means, which allows once the Have has been installed (3) a certain lateral tolerance movement of the shaft (31) of said Have to find the installation hole in the body.

As can be seen from the previous construction details of each part (1, 2 and 3) of the device and the graphics that accompany the present invention, this represents a fixing device for maintaining a fixed distance between a support element and a cladding element, chassis and panel for example the door of a vehicle, having a service position in which the three parts are pre-mounted in a stable position that cannot be accidentally separated, said position being the starting point for easy installation.

The installation of the device could not be easier. Although it can be done in different ways depending on

5

10

25

30

the preferences of the installer, one of them is to fix it from the pre-assembled or service position in the panel or cladding and press it against the hole provided in the body or chassis for fixing it. The force of application or thrust provided by the Have (3) that displaces the assembly towards the inside of the placement hole makes, locked by the conical trunk shape of its axis (31), the locking of the three parts (1, 2 and 3 ) in its installation position where the fingers

(12) of the nut-clip move from the valley (36) to the valley (36 ') of the Have.

On the other hand, in the relation between the bushing (2) and the clip nut (1) there is a movement of the hook (14) of the clip nut (1) from the first step (23) of the bushing (2) to the step (23 ') of the installation position. This process is secured or driven by the flange or one (15) that acts as a stop between two guides (22) of said bushing (2), preventing a rotation or rotation movement between both pieces.

In this position the fingers (18) are pushed out, opening the flexion tabs (15); the flare of said flanges (15) ensure the union between said nut-clip (1), with the help of the bushing (2), in fixing the assembly to the body of the vehicle, by preventing the removal thereof.

These flanges (15) have a structural reinforcement (19) on their inner part, on the inside of the piece. In the bushing part (2), the windows (26) thereof allow space for said structural reinforcement (19) in the

5

25

preassembled position of the assembly, without flare the eyelashes, as shown in figure '11.

The set of the different pieces (1, 2 and 3) of the device is made of plastic of nature and suitable properties, according to the known technique related to fixing elements, being the selection of materials suitable for the present purpose.

Thanks to the constructive nature of the device of the present invention, an assembly has been made possible that presents a pre-installation position between its parts, which is easy to apply until its final application position and which, if required to be removed, allows disassembly. partial of it since the nut-clip assembly (1) and bushing (2) are fixed in the chassis of the vehicle, allowing the removal of the Have (3) from said union and the removal of the lining without necessarily having to recover the assembly of the clip that now provides an enclave point for the new fixation of the Have and installation of the cladding.

It is understood that in the present case, how many details of finish and shape may not alter or modify the essence of the invention can be variable.
