Description

Door and window hook fastener composite set

[technical field]

The utility model is about a kind of door and window hook fastener composite set.

[background technology]

Known door and window fastener, mainly be meant a kind of being located on the door and window, utilize handle for doors and windows to drive and be located at the interior fastener combination of window frame that the snap close of both sides produces displacement to make it expose to up and down, and then the draw-in groove of movable clip on the door and window fixed frame, and can control the keying of this door and window.

Being seen on the market at present known door and window fastener, different construction profile is arranged according to the window frame designs of different size, it comprises a kind of be used in flat window frame and a kind of design that is used in the slot type window frame, former structure as shown in Figures 1 and 2, it is a kind of U-shaped rail door and window fastener A, mainly be to use in this flat pulling on the formula window frame B as shown in Figure 3, this known door and window fastener comprises by a U-shaped slide rail 1a, one is located at the drive sheet 2a in the slide rail 1a, with the snap close 3a that is fixed in drive sheet 2a both sides, and be located at this combining structure central authorities, and the gearcase 4a that is offset to slide rail 1a one side constitutes; Wherein, be provided with the gear 42a that can penetrate the square hole 41a on it by the extension square bar of handle for doors and windows 5a and drive in the gearcase 4a, and then drive one with driving sheet 2a fixing toothrow 43a, make and drive sheet 2a generation slippage up and down, and then snap close 3a and the draw-in groove 61a on the fixed frame 6a of control both sides form movable clip, uses the keying of controlling door and window.

Other has a kind of known door and window fastener, is a kind of parallel rail door and window fastener C, its structure such as Fig. 4 and shown in Figure 5, and it mainly is on the slot type window frame D that is applied to as shown in Figure 6; Comprise by a plane slide rail 1b, and be located on the slide rail 1b drive sheet 2b be fixed in the snap close 3b that drives sheet 2b both sides, and the structures such as gearcase 4b of being located at these combining structure central authorities constitute; Wherein, be provided with the gear 42b that drives by square bar that handle for doors and windows 5b extends penetrates the square hole 41b on it in the gearcase 4b, gear 42b and then engagement drive to be located at and drive upward perforation 43b of sheet 2b, make and drive sheet 2b generation slippage up and down, and then the snap close 3b of control both sides and the draw-in groove on the fixed frame 6b (figure does not show) formation activity clip, use the keying of control door and window.

Above-mentioned two kinds of known door and window fasteners, its main difference is that both gearcase 4a, 4b are provided with the difference of position, and provide and drive sheet 2a, the slide rail 1a of 2b slippage, 1b appearance difference, and because this structural difference, therefore make both when actual installation is used, only can be applicable to the window frame moulding of respective specification, that is as is exchanged use and will cause and can't use or situation that function of use is not good; Wherein, B (window frame as shown in Figure 3) when planting flat window frame in addition as aforementioned parallel rail door and window fastener C is used in, then will make this door and window fastener be combined in when installing and to obtain suitable support, and also make it drive sheet 2b slippage normally and fasten use, therefore known parallel rail door and window fastener C its mainly be that design is used in slot type window frame D, and can't be applied on the flat window frame B; Otherwise, when this U-shaped rail door and window fastener A is applied to slot type window frame D, then because this type door and window fastener, what its gearcase 4a was looked by the side is a side that is offset to slide rail 1a, therefore window frame as shown in Figure 6 when it is installed on the slot type window frame D, then easily lock when placing this slot type window frame D cooperating with handle 5a square bar because of its gearcase 4a, gearcase 4a does not obtain good supporting, therefore make gearcase 4a not cause the situation of distortion deflection at that time and easily, and then cause flaw after making whole group door and window hook be buckled in installation in the setter application of force.Therefore, the door and window fastener of different size only can be applicable to that special-purpose window frame is a undisputable fact.Yet, also can learn the door and window fastener combination of tool U-shaped slide rail 1a according to aforementioned experience, because of it has the preferred positioning effect, therefore still applicable to the window frame of two kinds of different sizes, and should change the structure design of its gearcase 4a, use the needs that are adapted to two kinds of different sizes.

Secondly, aforementioned two kinds of known door and window hook fasteners, it drives

sheet

2a, 2b and all must be positioned on a slide rail 1a, the 1b, can make

drive sheet

2a, 2b be slippage start up and down, yet long and

slide rail

1a, 1b improperly, except that the space that has taken esconson, and the increase of material improves the manufacturing unit price of every group of door and window fastener during also because of manufacturing, form the increase of cost of manufacture, reduce the market competitiveness, therefore also treat further to cooperate the disappearance of aforementioned variety classes specification hook fastener and improved in the lump.

Moreover, the door and window fastener of two kinds of known kenels, the manufacturing compound mode of its gearcase 4a, 4b is please extremely shown in Figure 6 referring to Fig. 1, it mainly is fixed bin frame 44a, the 44b that utilizes on

slide rail

1a, 1b, in its outside enclosing cover one

lid

45a, 45b, and in

lid

45a, 45b both sides each is fixed with

rivet

46a, 46b; Yet, this mode is when reality is used, as because of the application of force improper, for example working as

handle

5a, 5b closes at window, when fixed card slot desire row is closed on the locking mechanism of gearcase 4a, 4b and the window frame, because the improper generation bump of the application of force, and make its torsion that produces put on this gearcase 4a, 4b, and make

fixed rack

1a, 1b under gearcase 4a, the 4b produce bending because of torsion, simultaneously may cause

lid

45a, 45b to come off from box frame 44a, 44b, influence the normal use and the life-span of this door and window fastener combination, therefore treat further to improve.
