Abstract
The invention relates to a safety protection window, which comprises a window frame, a first sash and a second sash, wherein the first sash and the second sash are adjacently installed on the window frame, a sliding support mechanism for opening or closing the first sash is arranged between the window frame and the first sash, and the safety protection window is characterized in that: the sliding support mechanism enables the first sash to move towards a direction close to the second sash relative to the window frame in the opening process, the second sash is slidably mounted in the window frame, a push-pull mechanism is arranged between the first sash and the second sash, and when the first sash is opened, the push-pull mechanism enables the second sash to gradually slide towards the direction close to the first sash. The invention has the advantages that: when the first sash is completely opened, the maximum effective opening length of the window is shared by a gap formed between the first sash and the window frame, a gap formed between the first sash and the second sash, and a gap formed between the second sash and the window frame, so that the window has a safety protection effect.
Description
(1) technical field
The present invention relates to safety protection window.
(2) background technology
Chinese patent CN201220365996.2 discloses a kind of safety protection window, and it relies on the second sash 3
Forming part space after the first sash 2 is opened is filled up in translation, will not leave behind excessive space in opening,
Preferable security performance purpose can be reached, but in use there is also a little problem and fail to obtain well
Solve, be specifically expressed as follows: if a length of 0.8m of window frame, the first sash and the length of the second sash
Being respectively 0.4m, window frame is just sealed when closing up Guan Bi by two sash, in order to allow air more circulate, and people
The longer the better to wish the length of effectively opening of window, therefore (the i.e. first window after the first sash fully opens
Fan is perpendicular with the second sash), window is maximum effectively opens a length of 0.4m, utilizes Chinese above-mentioned patent
Technical scheme, the maximum length of effectively opening of this 0.4m can only be formed between the first sash and the second sash
Gap and the second sash translation after with the gap of window frame apportioned by.Practical situation is, the most how to share,
Among two gaps, the affirmative of any one is not less than 0.2m, and the length of 0.2m can meet a people from room
Export-oriented indoor are passed through, and therefore do not have the effect of antitheft increase safety guard, on the other hand, the length of 0.2m
Degree is not enough to prevent child from passing through to outdoor from indoor, it is thus possible to child can be caused to pass through from window
And there is accident.
Therefore, the technical scheme of this patent has necessity of improvement.
(3) summary of the invention
It is an object of the invention to provide safety protection window, effectively open the same of space meeting the maximum of window
Time, have more security protection effect.
For achieving the above object, the present invention is by the following technical solutions:

In block 42 inserts described second slide rail 41 and can be along the second slide rail 41 sliding.Described first connecting rod 43 one end
Being hinged on window frame 1 and its other end is hinged on the first sash 2, one end of third connecting rod 45 is hinged on described
On first sash 2, the other end is articulated with on described second slide block 42, and one end of second connecting rod 44 is articulated with
On described second slide block 42, the other end is articulated with between first connecting rod 43 both ends, described first connecting rod 43
Parallel with third connecting rod 45, the described first connecting rod 43 pin joint on the first sash 2 and described third connecting rod
45 form a line (in Fig. 9 shown in L) between the pin joint on the first sash 2, and this line is with described
The line (in Fig. 9 shown in M) that second connecting rod 44 is formed between two pin joints is parallel.
The second structure can be as Figure 11 is to shown in 12, and it is with the first structure difference above-mentioned:
1, one end of described first connecting rod 43 is to be hinged on the second slide block 42 rather than be hinged on window frame 1
's；2, respective one end of second connecting rod 44 and third connecting rod 45 is respectively articulated with (the hinge each formed
Contact can overlap also can be misaligned) on window frame 1 rather than be hinged on the second slide block 42.Concrete next
Saying, described first connecting rod 43 one end is hinged on described second slide block 42 that its other end is hinged on first
On sash 2, one end of third connecting rod 45 is hinged on described first sash 2 that the other end is articulated with institute
Stating on window frame 1, one end of second connecting rod 44 is articulated with the other end on described window frame 1 and is articulated with
Between one connecting rod 43 both ends, described first connecting rod 43 is parallel with third connecting rod 45, and described first even
Hinged on the first sash 2 of the bar 43 pin joint on the first sash 2 and described third connecting rod 45
Forming a line (in Figure 11 shown in L ') between point, this line is formed with described second connecting rod 44
Line (in Figure 11 shown in M ') between two pin joints is parallel.
Described second sash 3 is arranged in window frame 1 slippingly.The top of described second sash 3 and the end
Portion is provided with pulley, and described window frame 1 is correspondingly arranged on guide rail, and described pulley coordinates installation with described guide rail.
It is provided with a push-pull mechanism 5, when described first sash 2 between first sash 2 and the second sash 3
In opening procedure, described push-pull mechanism 5 makes described second sash 3 gradually towards near described first sash 2
Direction (such as B direction in Fig. 3) sliding.
Specifically, as shown in Figure 3-4, described push-pull mechanism 5 has a push rod 51, push rod 51
One end is hinged on described first sash 2, and the other end of push-pull bar 52 is articulated with on the second sash 3.
Described guide rail is arranged near window frame 1 front end face, before described second slide rail 41 is away from the first sash 2
End face is arranged, and described first slide rail 21 is arranged near the first sash 2 front end face, when described first sash 2
During Guan Bi, described guide rail and the second slide rail 41 are the most on the same line.
Described slide-support mechanism 4 and push-pull mechanism 5 are respectively arranged with two sets, and correspondence is installed on window frame 1 and sash respectively
Between top and between window frame 1 and sash bot-tom.
In practice, as shown in the drawings, described first sash 2 on the right of described window frame 1, when
After described first sash is opened, between the left frame of described first sash 2 and the right frame limit of window frame 1 are formed
The gap of formation and the second sash between the right frame limit of gap, the left frame 2 of the first sash and the second sash 3
The width in the gap of the left frame limit formation of the left frame of 3 and window frame 1 is all in the range of 0.12～0.17 meter.
Embodiment two
The present embodiment is to be improved further on the basis of above-described embodiment.Different places is this
The push-pull mechanism 5 of embodiment is different from the push-pull mechanism 5 employed in above-described embodiment.Specifically,
Also it is equipped with the first slide rail 21 on described first sash 2, has one first slide block 22 to insert described first sliding
In rail 21 and can be along the first slide rail 21 sliding, described push rod 51 be hinged on described first sash 2
One end is arranged on described first slide block 22, and described push-pull mechanism 5 also has a pull bar 52, described in draw
One end of bar 52 is articulated with on described first slide block 22, and the other end of pull bar 52 is articulated with on window frame 1.
Push-pull mechanism 5 can be made more stable by this improvement, it is easier to be turned on and off the first sash 2.
Above-described embodiment is the better embodiment of the present invention, but embodiments of the present invention are not limited to this,
The change made under other any spirit without departing from the present invention and principle, modify, substitute, combine,
Simplify, be the substitute mode of equivalence, within being included in protection scope of the present invention.
