Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a slotted fastener that can be assembled quickly and firmly onto a supporting slot of a metal plate.
In particular, it relates to fasteners for assembling vehicle door finishing flanges onto the door itself.

Vehicle door finishing panels currently consist of a barrel-shaped flexible stem designed to fit tightly into a seat formed on the support flanges of the door and a barrel-shaped flexible stem formed on the finishing flanges. assembly using a plastic fastener including a head integral with the stem, the plastic fastener having a T-shaped end to engage throughly into the slot inserted and lock within the finishing panel by approximately qo0 turns of the fastener; \There is.

The known fasteners are first installed onto a finishing panel by inserting the heads into several slots formed on the finishing panel and then turning each fastener. The finished panel so equipped is then placed against the support panel of the door, the stems being screwed onto the fasteners and the stems extending into the seat formed on the support panel. Try to get into it,
Attach onto the door by pressing the finishing panel firmly down into the area above the fastener.

The aforementioned fasteners have several drawbacks, chief among them being that the T-end cannot be rotated accidentally once it has been accommodated in the corresponding slot on the finishing panel. To prevent this, it is necessary to provide tabs in the head of the fastener on both sides of the T-shaped end. Therefore, once the fastener is inserted and turned, some slack remains between the fastener and the finished panel, and that slack is essentially equal to the axial length of the tab, and during travel. They do not cause vibrations and therefore can also cause noise between the assembled finishing flanges and the door. Additionally, finishing panels, usually made from plastic foam or compressed board, are rarely of uniform thickness, so the barrel stems on the fasteners installed on the finishing flanges all have support points. It does not necessarily engage the corresponding sheet on the groove, resulting in poor assembly of the finishing groove on the door.

The object of this invention is to overcome the aforementioned drawbacks.
The head on the fastener should be It is an object of the present invention to provide a panel fastener, particularly for a vehicle door finishing panel, which is designed to eliminate looseness between the finishing panel and the finishing panel itself.

With this object in mind, the present invention relates in particular to a panel fastener for fixing a vehicle door finishing panel, the panel fastener engaging in a seat provided in a support panel supporting said finishing panel. a female member,
a head integrally connected to the finishing panel; and a stem that fits tightly into the female member to deflect the female member in a radial direction and lock the female member within the seat. 1. The stem of the male member is disposed at the opening of the female member and is connected to the female member via a penetrable membrane so as to be integral with the female member. do.

Hereinafter, non-limiting embodiments of the invention will be described with reference to the accompanying drawings.

In Figures 1 and 5, / indicates a fastener for fixing the finishing panel of the door onto the support panel 3 of the sheet metal forming the door of the vehicle. Support panel arc finishing panel, 2
It has several seats consisting of holes for receiving parts of the fastener/fastener. On the other hand, if the finishing panel is made of several layers of polymerized dissimilar materials, the finishing panel is assembled onto the support panel 3, as shown in FIG.

In the front it has several slots 5 for receiving fasteners in a stable manner. According to the invention, the fastener has a female member 6 that engages with the seat of the support panel J, and a head G that fits into one of the slots 5 of the finishing panel and is connected to the finishing panel. , the female member 6f is inserted tightly into the female member 4! : includes a male member 7 having a stem which bends radially and locks the female member in the seat.

The male member 7 and the female member 6 are integrally connected, with the stem of the male member passing through the membrane 10fr of the female member. The fasteners are preferably molded from synthetic resin in suitably designed molds.

The female member 6 includes a U-shaped flexible bracket /l which is movably fitted into one of the seats of the support panel 3, and said bracket //.
A circular rigid section is formed integrally with the bracket// on the end//3 of the frame and acts as an axial shoulder or stop that abuts the support panel 3 when the female member 6 is inserted into the seat. flange 7.2. The bracket 7 opens towards the end /3 and has an internal recess /3 for receiving the stem 9.
S, and also acts as an axial shoulder for the support panel 3 when, for example, the stem is inserted into the recess 15 and the platen) is bent radially, and the conical member 4
A pair of opposing ribs/lI are provided on the outside to lock into the i seat. Viewed from the flange saw side, i.e. the end /J, said recess 15 has a flared part /6 on the female member 6 facing the opening, i.e. towards the end /J, and a tooth /6 on the middle part of the stemter. Several opposed, preferably rounded t-shaped stems are selectively locked in the recess/recess in different operating positions as shown in Figure 2.3.4.
If the fastener / is connected with a toothed intermediate part having triangular teeth /g, it is partially housed in the flared part IA and connected to the flange /λ through said penetrable FMIO'x. a wedge-shaped end on the stem;/a fully-receiving end portion 20; The membrane 10 is preferably formed by thinning a portion of the flange/λ, and forms a connecting member between the male member 7 and the female member B.

The head g of the male member fits into slot 3,
As shown in Figure 5, when you turn the fastener 90 degrees, both ends become slotted! If you turn the fastener as described above, it will prevent the fastener from turning any further than that, and at the same time prevent the finished panel from turning.
o It includes a collar with a stop tab 26 that fits snugly into the slot to prevent the head from being accidentally removed from the slot.

The flange R is designed to be flexible and the tab 26 is designed to fit tightly into the slotter, and the flange 30 is located on the two opposing ends 2S. Each end 2 is located on opposite sides of a T-shaped end plate.1. The lateral grooves formed on the back surface 30 of the collar 3 make it easy to bend.

In use, the fastener / is shown in FIG. 1, as previously described, on the T-shaped end -411! on the head g! −
insert it into the slot and attach it to the finishing panel, then turn the fastener in the direction of the arrow in Figure 5 to secure the end 24If.
It is set perpendicular to the slot 5 as shown in FIG.

When attaching the fastener to the finishing panel, insertion of the T-shaped end 2 into the slot s is prevented by the tab contacting the finishing panel λ. However, since there is a flexible end, it is a slot! By pushing the T-shaped end, 24t, inside and bending the collar, the operator can completely insert the T-shaped end, and then turn it. /l - Can be locked onto finishing panel λ. In this way, when you turn the fastener 1x9o, the tab n that was sliding on the back of the finishing panel is now a slot! In the state of entering, Tsuba J returns to the original position and Tabukoro is the slot! It snaps inside. Therefore, due to the special design of the head t and the particularly flexible tsubako,
It is clear that the fasteners I can be assembled on the finished panel without loosening, and that the finished panel can be assembled reliably and without vibration.

After all the fasteners /l are installed on the finished panel, the panel can attach the female member 6 of the fastener / on the finished panel λ to the support panel that forms part of the door of the vehicle.
Insert it into the seat (Fig. 1). In this state, the finishing panel is not yet fixed to the support panel 3. Then, an operator applies appropriate pressure on each fastener l on the finishing panel, for example, a portion on the finishing panel a, and presses the membrane 1 and the male member against the female member B. Note that the membrane 10 is sufficiently thin that the male member can easily tear the membrane IO.

Thus, when the membrane 10 ruptures, the pressure exerted on the finishing panel causes the stem to pass through the opening on the female member 6 into the recess l! It enters inward, and tooth/9 meshes with tooth/1. The stem t is slightly wider than the recess 13, so the stem t is wider than the recess 13.
When inserted inside, the platen shown in Figures 2, 3, and 4 will be bent into a barrel shape, and the rib /Q will cooperate with the support panel J. Then, insert the flange l inside the seat.
The female member 6 is locked in the axial direction with this. Recess/! The insertion depth of the stem into R is determined by the size of the gap that should be allowed between the finishing panel and the support panel 3 when the edge of the finishing panel is flush with the support panel J, and by the size of the gap between the finishing panel and the support panel. Depending on the shape, there may be differences on different parts of the finished panel. Teeth /1 and /? ?
By providing fasteners/fasteners that can reliably and securely lock the finishing panel onto the support panel J without unnecessary force, it can also be applied to various gap sizes between the finishing panel and the support panel J. It also has corresponding different connection positions. More specifically, as shown in this non-limiting example, a pair of opposing teeth /g and a pair of opposing teeth /g
Female member 6 and stem using 9? are shown in Figures 2 and 3.
Connected in three different positions as shown in Figure 4.
, are equally good from the point of view of a solid connection in all their states, and furthermore, for positioning the finishing panel λ, between itself and the support panel J (FIG. 2), or between A wide gap is provided between the support panel 3 (FIG. 4), which is essentially in contact with the support panel 3 (FIG. 4) in the position (FIG. 3).

The advantages of the fastener of the invention will be apparent from the foregoing description. It can be manufactured cheaply in a single molding operation and once assembled, the result is two batch parts, namely the female part 6 and the male part 7, and the workpiece on the door with the support panel J, For example, finishing Banelco can be quickly and easily removed in case of repair of the quick-actuation mechanism on the door itself. According to the invention, in fact, the bracket/l and the stem 9 are such that the effort required to release the stem 9 from the recess 15 is less than the effort required to release the female member 6t from the seat. The dimensions are as follows. Therefore,
When removing the finishing spring /I/, 2 f from the support panel J, the stem holder extends from the female member 6 along the recess /S, and conversely, the female member 6 remains fixed in the seat and is removed by the finishing spring. It is clear that this will be the case. The procedure for restoring the finished panel is no longer necessary for membrane 105.
-There is no need to break it, so it can be broken with very little effort. Since the bracket// and the stem are both made from the same plastic, the friction during the extraction is between the two plastic parts, as in the well-known fasteners.
It is not between plastic and metal parts.

The advantage of this is that much less effort is required to remove the finished panel from the support panel 3, compared to the known fasteners, so that accidental damage to the finished panel is avoided. - Finally, from the foregoing description it can be seen that the fastener according to the invention makes the overall assembly of the finishing panel much easier compared to known fasteners;
Fasteners according to the invention may be of unequal thickness and/or finished after assembly and one support panel 3
It is possible to securely fix finishing panels designed to have different gaps between them, and finally, once assembled, the finishing panels do not vibrate at all. It should be obvious that this can be done.

Although one embodiment has been described above, the present invention is not limited to this embodiment, and can be implemented by variously changing the design within the framework of the technical idea stated in the claims. can.

For example, to lock the prakut/no in the seat y,
The bracket) // can also be provided with flexible outer teeth.
