Abstract

The utility model relates to a freedom positioning bolt for opening and closing a window sash, composed of a supporting rod, supporting rod screws, a handle, a control key, a walking device, etc. The walking device walks in a walking groove, and the control key controls the walking and the braking of the walking device and also simultaneously controls the telescoping of the bolt. When using, as long as the handle is held by one hand, and the control key is pressed down, the freedom positioning bolt can push or pull the window sash so as to accomplish the function of opening and locking the window sash, and the opening angle of the window sash can be arbitrarily selected.

Description

Freedom positioning bolt

The utility model is a kind of free fastening screw that sash is opened, closed that is used for.

At present, wooden sash generally uses the plug-in type latch, and steel sash uses rotary latch.The effect of these two kinds of latches all is single, is fixed in the window frame after promptly sash being closed, and if desired sash is opened certain angle, makes room ventilation, and just other use window catch or utilization rotation fixedly strut are finished.Sash utilizes window catch to open, and angle is fixed, Jackstay type is after sash is opened certain angle, and rotation is fixed strut and finished the sash opening angle again.These two kinds unlatchings, the mode of pinning sash than more complicated, promptly need make and open or pin a fan window, need both hands to carry out simultaneously.Just harder when in use running into the latch of corrosion and strut.

This device, solving the sash opening angle can select arbitrarily, and easy to adjust, flexible, laborsaving.

The utility model is a kind of free fastening screw that sash is opened, closed that is used for, have latch (3), strut (4), strut screw (2), handle (7), different is that an end of strut (4) is connected on the running gear (6) of walking in the walking groove (5).Running gear (6) is walking and the braking of handling tooth bar (15) control running gear (6) by operating key (8), and running gear (6) has horizontal wheels (10), road wheel (13) and engagement tooth plate (12).

This device has been owing to adopted the stepped type structure, thereby only needs the hand just can control operation in use, and simple, convenient, the angle of sash unlatching can be selected arbitrarily.

Fig. 1 is user mode figure, 1 window frame, 2 strut screws, 3 latches, 4 struts, 5 walking grooves, 6 running gears, 7 handles, 8 operating keys, 9 sash.

Fig. 2 running gear (6) front view, 10 horizontal wheels, 11 supports, 12 engagement tooth plates, 13 road wheels.

Fig. 6 tooth bar (15) control action schematic diagram, 14 springs, 17 positive drive bars, 18 supports, 19 supports.

Fig. 7 be among Fig. 6 A to view.

This device is that an end of strut (4) is fixed on the window frame (1) with strut screw (2), and strut (4) can rotate around strut screw (2).The other end of strut (4) is connected on the running gear (6), and can rotate.Running gear (6) is installed in walking groove (5), about walking.The structure of running gear (6) such as Fig. 2, Fig. 3 and shown in Figure 4, it is made up of horizontal wheels (10), support (11), engagement tooth plate (12) and road wheel (13).The tooth that engagement tooth plate (12) inboard has several to be meshed with tooth bar (15).The right and left respectively has the horizontal wheels that can freely rotate (10) of getting up with support (11) supporting thereon, front and back two ends have four road wheels (13), along the cell wall walking, walk about bottom land in walking groove (5) by road wheel (13) in walking groove (5) for horizontal wheels (10).The strut (4) that whole running gear (6) drives on it rotates, and supports sash (9) opening and closing.

Running gear (6) is controlled its walking and braking by operating key (8).Simultaneously, operating key (8) is also controlled the flexible of latch (3).When pressing operating key (8), positive drive bar (17) moves upward under the effect (bar thick stick principle) of operating key (8), drives latch (3) and moves upward, be i.e. latch (3) withdrawal.Simultaneously, whole system drives tooth bar (15) and upwards turns over an angle under the effect of positive drive bar (17), makes tooth bar (15) and engagement tooth plate (12) throw off, and at this moment, running gear (6) is in walking states, can sliding window sash.Otherwise, unclamp operating key (8), under the effect of spring (14), the positive drive bar restores, and promptly moves downward, and makes latch (3) also move downward, and latch (3) promptly stretches out; Tooth bar (15) also restores (extreme position is established a baffle plate) simultaneously, is meshed with tooth bar on the engagement tooth plate (12), is fixed on a certain position.Like this, sash is lockable motionless with regard to opening certain angle.If sash is closed, latch (3) stretches out and has just firmly fastened window frame.

Claims

1, a kind of free fastening screw that is used for the sash unlatching, closes has latch (3), strut (4), strut screw (2), handle (7), it is characterized in that an end of strut (4) is connected on the running gear (6) of walking in the walking groove (5).

2, free fastening screw according to claim 1 is characterized in that, running gear (6) is walking and the braking of handling tooth bar (15) control running gear (6) by operating key (8).
