Summary of the invention

It is an object of the present invention to provide a kind of fixing retaining clip of hidden being different from above-mentioned clip, this clip is better than one or more above-mentioned clips.

The applicant has been developed over the fixing retaining clip of a kind of novel hidden, and compared with above-mentioned clip, the structure of this clip is relatively easy, and one or more that at least can match in excellence or beauty in above-mentioned clip in performance.

The invention provides the fixing retaining clip of a kind of hidden, for roofing board or other covering plate are fixed to the supporting construction of following common form, this clip includes:

(a) base portion;

B () a pair stretches out from this base portion and to the sidewall drawn close together; With

C () pair of flanges, described flange forms (define) keeper, and for engaging with the recess in the sidepiece covering rib of slab bar, one of them flange stretches out from the upper end of a sidewall, and another flange stretches out from the upper end of another sidewall.

The clip of the present invention has many features as described below, and these features improve the performance of this clip in many importances.

One aspect is resistant to act on the ability of the climbing power covered on plate.

Acting on the climbing power on mounted covering plate can cause covering plate to get loose the fixing retaining clip of hidden. Due to environmental factors, climbing power is likely to be produced by following reason:

A () covers the sidepiece of rib of slab bar to external rotation, thus separating with the flange of clip; And/or

B the flange of () clip is folded upward at, get loose from clip so that covering plate.

Another aspect is, when covering plate and being positioned in the fixing retaining clip of hidden, it may occur however that to the damage covering plate.

Specifically, it has been found that, with known clip, especially there is the clip of relatively short and hard keeper together with the covering plate that uses, when being forced on clip, it is easy to the problem producing indenture. When covering plate and being forced on clip, the part carrying out contacting and slide above clip covers in plate and can form indenture. Indenture is without influence on the mechanical performance covering plate. But, indenture can affect and cover the attractive in appearance of plate, and this is a noticeable problem.

Another aspect is, when fixing dismounting retaining clip by covering plate from hidden, it may occur that to the damage covering plate.

Specifically, it has been found that, it is difficult to when not damaging covering plate, plate will be covered from known clip, especially from dismounting the clip with relatively short and hard keeper. This is a noticeable problem, because often having such situation, for instance, when air-conditioning is installed on roof, it has to be possible to remove and cover plate to enter in the roof space, then again the covering plate of dismounting is installed onto original place.

For above-mentioned situation, the clip of the present invention includes following characteristics.

Preferably, the sidewall of clip of the present invention is formed, and manufactured form (as-manufacturedform) lower wall at clip does not contact with each other, and the in use described inside move toward one another of sidewall stress or contact with each other when covering plate and being positioned on clip. Because having gap between the sidewall of clip, for insertion into screwdriver thus contributing to being fixed in structures below clip, so this feature makes it is easier to be installed in structures below clip.

Preferably, sidewall and base portion are straight flange, thus when as viewed from during the side of clip, sidewall and base portion form a triangular structure. This structure improves bulk strength and the hardness of this clip. More specifically, this triangular structure improves the ability that this clip bears the downward load of clip, for instance, when someone is pressed downward against the rib covering plate to be pressed onto on clip by rib time. Additionally, this triangular structure can adapt to the downward load of the offset from center suffered when covering plate and being pressed downwardly onto on clip. Specifically, the sidewall of this clip can slide relative to one another along with the downward load of offset from center, and returns back to initial profile. Additionally, this triangular structure contributes to stoping sidewall to be displaced outwardly exceeding the shaping position (as-manufacturedpositions) of sidewall, and thus become this clip and can overcome the factor acting on the climbing power covered on plate.

Preferably, each sidewall includes one or more ribs, to improve intensity and the hardness of this sidewall.

Preferably, at least one limit of each sidewall includes an aduncate flange, to improve intensity and the hardness of this sidewall.

Preferably, when covering plate in using and draw close along with the stress of sidewall and being positioned on this clip, described flange forms at least one of bow-shaped structural. This feature improves this clip and overcomes the ability acting on the climbing power covered on plate. Specifically, this feature has arched advantage, and this structure is a kind of structure that climbing power can be transformed into outside power.

Preferably, covering plate and be positioned on this clip and when sidewall stress is drawn close in using, described sidewall contacts with each other or close to each other near the upper end of this clip or the upper end of this clip. This feature ensure that the material of clip is as closely as possible near this arched summit, thus helps in clamp material as much as possible and concentrates on the top of clip, thus optimizing the intensity of this part of clip.

Preferably, when look clip be oriented to clip base be on horizontal plane time, described flange outwardly and downwardly extends relative to one another.

Described flange can form the approach angle of a comparable steepness relative to the rib covering plate, when in using with box lunch, covering plate is pressed downwardly onto on clip to be positioned on this clip by covering plate, the sidepiece covering rib of slab bar is mild rather than unexpected being deflected outward by.This feature contributes to making covering plate indenture minimize.

For this configuration, flange is preferably relatively long, it is preferable that be at least the 25% of clip height.

The approach angle formed by each flange and the base portion of clip is preferably between 40 ° and 75 °.

Alternately, flange can form an approach angle relatively mild relative to covering rib of slab bar, when in using with box lunch, covering plate is pressed downwardly onto on clip to be positioned on this clip by covering plate, the sidepiece covering rib of slab bar is unexpected rather than mild being deflected outward by.

For this configuration, flange is preferably relatively short, it is preferable that less than the 25% of clip height.

The approach angle formed by each flange and the base portion of clip is preferably smaller than 40 °.

Each flange preferably has sharp keen outer end, and when in using, this covering plate is positioned on clip, the contact of described outer end also thus engages with the recess covering one of rib of slab bar securely.

The outer end of each flange preferably stretches out. In other words, the outer end of each flange preferably sidewall not towards clip curves inwardly.

Preferably, each flange includes two corner parts, and described corner part bends inwards, and forms the surface extending transverse to flange outer end, and when covering plate in using and being positioned on clip, the contact of described surface also thus engages with the recess covering one of rib of slab bar. This feature adds the contact surface area between flange and recess, minimizes thus enabling to the infringement to covering plate when covering plate from dismounting clip.
