The specific embodiment

Figure 1 shows that is hit a plate, refer to label 1 generally that the described plate that hits designs in existing mode basically.Therefore, hit plate comprise a groove, passage, slit or similar structures 2 can with a locking element cooperation, locking element can be ratchet, ratchet or like.As shown in the figure, groove or similar structures 2 have a wall surface 2a and relative with a wall surface 2a substantially wall surface 2b, and described wall surface 2a restriction is towards the direction opening of doorframe or window frame.Hit plate 1 and be fixed to usually, normally be installed in groove milling or the similar structures, can utilize bolt or like to install by bolt hole 4 as on door or the window frame.As depicted in figs. 1 and 2, these bolts hole 4 are arranged in the wall portion 6 that hits plate 1, and wall is provided with recess 9 to hold bolt head.Thereby hitting plate 1 can also be provided with additional holes window or door are fixed to the vent position place.

Therefore be understandable that the locking element on movable part such as sash or door leaf when being inserted in the opening 2, because locking element abuts against wall surface 2b, thereby holds out against doorframe or window frame with movable part, can prevent to open movable part.Particularly, wall surface 2a does not then possess function corresponding, and this is because in fact window frame has limited the cause of the snap close position of moving-member, but is understandable that opening 2 must have wall surface 2a, this wall surface 2a also may with the locking element cooperation.

As Fig. 1, Fig. 2 and shown in Figure 3, the present invention hits plate 1 and also can be designed to, and groove 2 is wall surface 2b or its part at least just, adjoins the upper side edge that hits plate by the chamfered edge or the chamfered portion 8 of certain angle.

Figure 3 shows that along the sectional view of III-III line among Fig. 2 the plate that hits of present embodiment has a surface 12 and connecting wall surface 2a hitting plate 1 rear portion.Hit plate surface 12 with respect to wall surface 2a generally speaking inwardly with upward to inclination, wall surface is shown as vertical trend basically in Fig. 3, and forms one less than 90 ° turning.Hereinafter will describe its effect in detail.

Hereinafter with reference to the accompanying drawings 4-6 pair be described in detail with the above-mentioned locking element that hits the plate cooperation.In illustrated embodiment, locking element refers to label 20 generally, and locking element can be a longitudinal bodies 24, which is provided with a mechanism 22, by described mechanism 22 locking element is connected on the locking device.Therefore, mechanism 22 can be an axostylus axostyle or rotating shaft, but is understandable that locking element is a pivot type, and example is tip ratchet (pasquil pawl) as is known in the art.Lengthwise body 24 is slight curving according to prior art with detent mechanism (pasquil system) logotype the time.Yet, be understandable that the locking element of other types also is fine.

Be provided with an outstanding projection or similar structures 26 at the other end on the locking element, as shown in FIG., this structure 26 is arranged on the upper surface 28, and its function will be described below.In addition, inclined-plane, curved surface or similar structures 27 can be as shown in Fig. 5 and Fig. 6, and its function is, if having opening 2 or chamfered portion 8, then when window or door leaf by snap close or when being fixed to vent position, can more easily locking element be inserted in corresponding opening 2 or the chamfered portion 8.

Fig. 7, Fig. 8 and Fig. 9 show mutually combine hit plate 1 and locking element 20, and be in and attempt situation that the lock system is opened by force.

For further explanation, Figure 10 shows the situation of attempting to open by force.As shown in FIG., framework 30 is as window frame or doorframe, also with sash 31 and window 32 expressions.Be appreciated that framework and sash hit plate 1 by one or more groups and locking element 20 locks onto together, these hit plate 1 and locking element 20 is not shown in the drawings.

One as crowbar, screwdriver or similarly instrument 34 be inserted between window frame 30 and the sash 31, window is pried open attempting by apply power in the direction of arrow.Instrument 34 a bit tiltedly prizing on window frame 30, the outer of window frame for example, be appreciated that sash 31 be subjected on the one hand power Fn upward to effect and be subjected to power Ft effect (shown in Figure 10) in the horizontal direction on the other hand, thereby attempt sash is released from window frame.Be understandable that power (making a concerted effort) will influence the combination of hitting plate 1 and locking element 20 as shown in Fig. 7-9.Power Fn attempts to move out in the opening 2 of an end from hit plate 1 with locking element 20, and simultaneously, power Ft influences locking element in side direction.When locking element 20 during against the sidewall 2b of opening 2, because the material and/or the suspension situation of locking element can collapse under the effect of power, locking element can tilt and present illustrated obliquity.As shown in the figure, the chamfered portion 8 of sidewall 2b can be designed as the suitable control that obtains this displacement in the displacement of locking element.As shown in the figure, the projection 26 that is arranged on the sidewall of the sidewall 2a in locking element frame oriented and the opening is lived by surperficial 12 snap closes, and as previously described, surface 12 is arranged on the back of hitting plate 1 and adjoins sidewall 2a.As can be seen from Figure, surface 12 can form and be located at the groove that hits plate 1 back or the part of similar structures.Groove can be designed to corresponding to the size of the projection on the locking element 1 26 and/or shape.Yet, when locking element 1 supports chamfered portion 8 with a side and when supporting sidewall 2a or its low limit with another side or end, the established angle on surface 12 is regulated the angle of preferably setting corresponding to the upper side edge 28 of projection 26.Projection 26 upper side edge 28 can be designed as the side that is basically perpendicular to locking element 20, but angle also can with vertical off setting.For example, the angle of formation can also can obtain effective snap close less than 90 ° between two elements, can certainly adopt a bigger angle.

Be appreciated that shown in Fig. 9 (Figure 10) in case power applies up, because its angle changes when upwards mentioning locking element, locking element 1 presents shown position.Specifically, should be noted that each parts should be designed to projection 26 and directly be held by surface 12, but also can be designed as when locking element presents such angle,

sidewall

2a, 2b limit further angle to be changed, and the upper side edge of projection 26 still can not support surface 12.This reaches by adding power at locking element.In this manner, can guarantee to hit plate locking element 20 with respect to hit plate 1 locking.

In addition, choose by the suitable dimension to each element, when locking element is positioned at position shown in Fig. 9, making a concerted effort (synthetic by Fn and Ft) can be in the direction of locking element or basically along pointing on this direction.When attempting window, door or respective element opened by force, active force can be absorbed by the tension force (or being essentially tension force) along the locking element direction.This means that also the ruined danger of locking element has minimized.

Locking element is snapped into the device that hits on the plate, be shown projection 26 or similar structure in the drawings, also have other snap close modes certainly, some of them are shown among Figure 11 a-11e.These illustrate the embodiment different with the locking element among Fig. 9.

For the ease of relatively, the embodiment corresponding with Fig. 9 has been shown among Figure 11 a, wherein bolt or similar structures 26 are arranged on the end of locking element, and its upper surface 28 can engage with the surface 12 of hitting plate 1.

The side that Figure 11 b shows locking element has the embodiment of recess 29b, and described recess can have different modes, but general, and it has a surperficial 28b who makes progress to engage with surface 12.

Figure 11 c shows the embodiment that has recess 29c in a side of locking element, and it is perpendicular with the longitudinal axis of locking element basically that described recess has a surperficial 28c who makes progress.

Figure 11 d shows another embodiment, and wherein, the mode that is used for snap close is designed to be positioned at structure or the protruding 26d on 20 1 sides of locking element, and described structure has and the vertical substantially upper surface 28d of the longitudinal axis of locking element.

Figure 11 e shows another embodiment, and wherein, locking element and side are provided with structure or protruding 26e, described structure be rounding but still have a significant upper surface 28e, described upper surface can engage with surperficial 12 hitting postlaminar part.

Can learn obviously that from top example and describing the angle of inclination of surface 28,28b, 28c, 28d and 28e can be dropped in the scope of broad, promptly with respect to the main body of locking element 20 or side greater than, less than 90 ° or equal 90 °.Yet certain condition is important for the inclination angle as shown in Figure 9, promptly supports locking element when hitting plate with respect to hit plate gradient that presents and the inclination angle of hitting plate respective surfaces 12 when dual-side.Therefore, hit position-also can the influence size of angle of point on the supporting surface/surface of the degree of depth of slit 2 of plate and width-locking element as can be seen.Same situation condition also is applicable to the angle Selection of hitting the plate surface.Therefore, be appreciated that the personnel that understand manual and claims can be according to the corresponding angular dimension of relevant structures shape when relating to content of the present invention, therefore, when attempting to open by force, also can obtain locking element and hit lock jail between plate.

For those of ordinary skills, do not exceed the embodiment of the scope of the invention outside describing above yet can finding out.Obviously, hit that lock catch part also can be designed to illustrate different modes with the present invention on the plate.
