Description

The chain coiler

Invention field

The present invention relates to the chain coiler, relate in particular to the chain coiler that is used for window.

Although the present invention can be applied to open or close a series of objects that comprise skylight etc., for convenience's sake, this sentences the chain coiler that is used to open or close the shelter window and explains.

Related application

The application requires the priority of No. the 2009906166th, Australian temporary patent application and No. 2009906278; These two applications are incorporated among the application; Also require the priority of No. the 2010101261st, Australian patent of invention and No. 2010101266, these two patents are incorporated among the application.

Background of invention

The present invention relates to window winder, this window winder uses chain to be connected to hinged window, changes the open angle of window through the length that changes chain with this.The invention particularly relates to lockable window winder, but be not limited only to lockable window winder.

Generally speaking, such mechanism is used on the window, and pivot knuckles is connected to windowsill at top and this window winder of window, chain extend from the bottom of window and be connected to window the bottom in case chain can be around the top the outside pivoted of hinge.

The special problem related with this type window winder is that fixing such window is difficulty.The excessive tension that is applied directly to the window bottom can cause excessive tension force in opening mechanism, cause the gap of the relative mechanism of chain.Drive unit even may rupture.Likewise, the power that continues that is applied directly on the window possibly only can be operated and the related gear drive of chain on the direction opposite with the activation direction of expection.By this way, owing to can change freely rotating of driving mechanism, the outside power that is provided on the window can be pulled out chain and openable windows.

Problem hereto, the solution of proposal is to use the stop device with gears engaged, and this band gear cooperates with chain.Another solution is to use the stop device that directly cooperates with chain, preventing more motion, thereby produces the effect of non-one-directional rotation locking mechanism.But because in first kind of solution, chain can only be locked on each tooth of gear, and in second kind of solution, chain can only be locked on each chain section, so these solutions all have its limitation.Therefore, locking can be depended on the interval of chain section.Can't be provided at the continuous locking system of acceptable commerce that any position can both effectively play a role like this.

What use in the modern window winder system is worm-drive, and worm-drive has the height ratio transmission and cooperates with chain with driven wheel.The essence weak point that can have like this is can need the too many time operating grip of upset just can obtain window and significantly move.Therefore, importantly, to allow maximum sized worm gear, and want to comprise size and all maximized locking device of intensity that to allow worm gear.

Another problem is constructional problem, and textural, the coiler of prior art needs a plurality of cast metal parts and a plurality of plastic components.Structure is generally understood more complicated and is constructed comparatively difficulty and expensive.Generally speaking, shell is processed by the metal hollow structure, and parts are in the enclosure assembled one by one.A special problem is that opening is at base portion, so all parts must be inserted into shell when shell is inverted.This means and to assemble on the orientation in use, and need mechanism to allow to insert and can maintain usually.Thereby the complexity of assembling increases greatly.

The present invention relates to window winder, this window winder uses and is connected to the chain of hinged window, so that make the length that changes chain can change the open angle of window.The present invention is especially relevant with lockable window winder, but is not limited only to lockable window winder.

Generally speaking, such mechanism is used on the window, and pivot knuckles is connected to windowsill at top and this window winder of window, and chain extend from the bottom of window and be connected to window the bottom in case chain can be around the top the outside pivoted of hinge strap.

One special problem is that window upstairs requires littler open angle than window downstairs, therefore needs short chain.But the supply short chain means the coiler that must select short chain before use for use, and chain will be punctured into required length.This is the very high approach of cost, needs participation rather than the manufacturer of retailer or setter or whole seller that finished product is provided.In addition, chain is cut ressemble after the size that is fit to and link can cause bigger complexity and higher cost.

Be known that to have the pin that to install in the enclosure in addition, the protrusion that can cooperate with the internal part of chain winding mechanism is provided.

Needn't break the benefit of drive unit although this provides, but still need separate housings and base portion inserting stopper or pin, thereby and this can cause unexpected disintegrate or at least the part parts from correct discharging, deviate to cause fault.

Another special problem is, is used to bear heavy chain greater than 20 kilograms power and as short chain, can't has with chain and cooperate to influence the arresting stop of stops.Its reason is that 20 kilograms power is enough to move any stops that cooperates with chain.

But the main aspect of chain coiler is to need to have the intensity of push-and-pull hinged window.

It is the device that heat and noise provide the central core of circulation that present window is considered to a kind of.Wall has buffer action, but isolation effect is significantly weakened by heat waste and noisy channel via window.For energy-conservation, window is becoming the insulating element of heat energy and noise.The insulating element that this needs double-layer glass usually and forms noise and heat energy thus.It is obvious that, and the bilayerization of glass can make the weight of window increase greatly.

Increase and receive under the state more energetically in this weight owing to window, present chain coiler can't be tackled the lasting use of window.But this is not only through using firmer material to gain in strength with regard to the problem that can solve.Can veto the more firm metal of use to the consideration of cost.It is feasible using thicker steel, but its main weak point is that system can't satisfy the construction requirement of standard, maybe can't be suitable for known chain coiler structure.

In view of the above, the objective of the invention is to, overcome or improve one or more weak point of the prior art at least greatly.

The improvement of handle aspect comprises:

I. folding handle is used to maintain the method for removable handle

Ii. handle extends from the shell outside, and fully passes shell and subassembly extension, to be in place by accessibility locking device outside shell.

Shown in Fig. 7 A, 7B and Fig. 3 A, 3B and the 3C be, to the further improvement of folding handle construction.Especially will be referring to Fig. 7 A, be configured in crank 52 and curved low constituent 54 that having on the handle 51 has axle 53, and axle 53 can extend with this curved constituent via drive unit, this drive unit comprises worm gear 43 and ratchet 45.Top handle part 55 is mounted to crank 52 through bent sub with folding style, and this bent sub comprises sleeve pipe 56A, sleeve pipe 56B and pivot pin 56C, and sleeve pipe 56A is installed on the crank 52 and intersects with sleeve pipe 56B, can maintain handle 55 through pivot pin 56C.When handle during in operational position, another spring mechanism 57 is positioned at two beads in the groove on the handle inner surface., coiler can eliminate unexpected possibility of extracting handle when being operated like this.When handle was pulled out, this spring mechanism can make handle remain on original position thereby this handle can be folded up.

Shown in Fig. 7 B is the handle 51 that has put in place; Driven wheel is installed in the shell 12; And stop pin 59 also maintains curved low constituent 54 from base portion 15 extensions with adjacency thus, and also thus the top component of chain coiler 22 is locked to base portion 15 at catch position holding handle 51.

The improvement of reinforcement feature aspect

The improvement of reinforcement feature aspect comprises tumbler gear and firmer chain.

In the preferred embodiment shown in Fig. 4 A and the 4B; Be further provided with through improved tumbler gear 31; Tumbler gear 31 has a plurality of peripheral teeth 35, and peripheral teeth 35 can cooperate with the far-end 22 of chain 21 when being installed into shell 12, so that be formed up to the arcuate passageway of chain.But, when heavy window being installed or being compelled window to be installed, can increased pressure be provided to chain 21 with rough mode, known tumbler gear just may be damaged by pressure.But and though tumbler gear of the present invention 31 is made of plastics enough intensity; Its reason is; Tooth 35 sides of layout and around medium pore 32 sides tops upright shoulder shape ridge 36 is all arranged; To realize auxiliary the reinforcing, reach for tumbler gear, can under situation about can not be damaged by pressure, realize the distinct arcuate passageway of chain 21.Likewise, to be installed in 41 last times of screw can solid integrated and make screw stretch with the style that is orthogonal to the chain plane when tumbler gear 31, and its reason is that tumbler gear can be resisted any torsional deflection.

Preferred embodiment shown in Figure 11 to 15 can be incorporated the chain coiler shown in Fig. 1 into; So that synergistic combination to be provided; Provided by the inventionly comprise many pins through improved chain; These many pin keeping parallelisms and spaced apart by Chain plate, thus, chain tooth can mesh and chain drive-belt with the pin that adjoins continuously; And it is characterized in that having one or more bracing means significantly to reinforce chain through improved chain.Figure 11,12 and 13 shows three kinds of distinct bracing means, but these bracing means also can combination with one another use.

Referring to the chain of Figure 11, used the adjacent chain batten.Chain is formed by parallel pin usually, and this parallel pin remains between the Chain plate of the U bodily form of overlapping, and the Chain plate of this U bodily form has open top so that chain tooth fitting pin and chain drive-belt in order.And with such structure, the sidewall of Chain plate body can extend around pin but can separate with next sidewall, and the plane that can adjoin of the Chain plate that overlaps.By this way, chain can free bend.

And found be, if Chain plate is used to be fitted to each other by manufacturing or under the pressurized situation, cooperates at least, perhaps be positioned to each other very near, like Figure 11 and shown in Figure 15, vertical cooperation of Chain plate can significantly be gained in strength so.Abutment surface can be curved like Figure 11, so that make the chain angular distortion that when keeping connection, still can rotate.In the adjacency structure of Figure 15, what illustrate is the curved surface of leading to the locking cam surface.

When using with the incorporate of U-shaped Chain plate and U-shaped intermediate chain batten; The degree of this compressed fit can significantly promote; And thereby the bending that the structure that provides of the combination of U-shaped Chain plate and U-shaped intermediate chain batten can prevent to exceed straight line portion is when when the opposite side of straight line portion is inwardly folding, can only snake and fold in the reception groove of window winder.Like this crestal line intensity can be provided when extending.

In the reinforcement mode of Figure 12, what illustrate is the mirror symmetry Chain plate that is connected between the end of two same pins, and the Chain plate that overlaps extends to down a pair of Chain plate between a pair of Chain plate.It is obvious that, and this reinforces in the amplification that also can provide under the situation that increases the chain width not significantly on the bigger intensity.

The overlapping of the Chain plate of Figure 12 part also can have mirror symmetry plate, perhaps can be alternately or the other forms of repetition of mirror symmetry plate so that make different pins bearing strength equably.

Referring to Figure 13, what Figure 13 illustrated effectively is double-stranded bar, it is characterized in that, the pin after the extension extends between Chain plate, and the length of extension is the half the of pin length or shorter than the length of pin, and is connected through overlapping to provide with middle body at the end of each pin.Therefore, the quantity of the Chain plate between the two adjacent pins can be increased to 4 or more from initial 2, and this can significantly gain in strength.

Although we have explained the special embodiment of chain coiler herein, thinkable in addition is that other embodiment of the present invention also can show described any amount of characteristic and any single combination of features before.But, it being understood that any variant and the alter mode of under the situation that does not deviate from spirit of the present invention, making all are included in of the present invention as in the protection domain that following claims defined.
