Description

Bolt for doors and windows with rotary hook

The utility model relates to a kind of rotational hook formula thumb-latch that is used for building window.

The latch that is widely used in building window now adopts the mode pull and push to be seated or to open, this draw and insert-type latch generally by be seated bar, be seated the bar installation sheet, be seated bar insert three of sheets in addition parts form.For being seated bar, the demand of intensity generally uses garden cylindricality Metallic rod manufacturing.This latch materials are more, and the function that is not seated automatically.Though also have this draw and insert-type thumb-latch is added shock mount to improve, it is had be seated function automatically, cost is higher, and functional performance is not good enough yet.

It is simple that the purpose of this utility model provides a kind of manufacturing process, saves metal material, can utilize elastic force or gravity to lock voluntarily when door and window is closed, the rotational hook formula thumb-latch that beautifies of being more convenient in appearance design.

Rotational hook formula thumb-latch is used to keep closing of building window.The utility model is made up of two groups of parts: 1. rotational hook parts; 2. hung parts.Rotational hook parts and quilt are hung parts and can other be made up of by part one or more.The rotational hook parts have a rotary part in addition at least.The utility model has three kinds of states when using.1. lock-out state, rotational hook parts tangle the state when being hung parts.2. opening, rotational hook parts do not tangle and are hung parts, and the state that yet do not rotate of rotatable other part of rotational hook parts.3. transition state, rotatable other part of rotational hook parts is rotating, rotational hook formula thumb-latch by lock-out state to the opening transition or by the state of opening to the lock-out state transition.Rotational hook parts and hung parts and be installed on door and the doorframe respectively or on sash and the window frame.Rotatable other part of rotational hook parts rotates under the effect of manual or spring force or gravity when door or sash are closed, and is suspended to be hung on the parts to be entered lock-out state, thereby reaches the purpose that keeps door and window to close.

The in addition part profile of rotational hook formula thumb-latch can make that butterfly shape, flower shape, toy shape, alphabetical shape etc. are multiple to have ornamental figure, and minimum to its cost influence.Also can adopt technology such as color plating is that outward appearance is hyperchromic.

The in addition part of rotational hook formula thumb-latch is except that spring and rotating shaft, and all the other all can adopt the metal sheet stamping parts.

The utility model is compared major advantage with the draw and insert-type thumb-latch that is widely used in the civil building door and window now: have the function that is seated voluntarily when door and window is closed; The flexible design of on overall styling, being more convenient for; Save metal material, manufacturing process is simple.

Fig. 1 and Fig. 2 show an embodiment who adopts hinge arrangement.Fig. 1 shows the quilt of this embodiment and hangs parts.Fig. 2 shows the rotational hook parts of this embodiment.Rotate hook part in the present embodiment by stator (4), hook (2) and axle (3) are formed.Hook (2) is pressed together with axle (3).When the rotational hook parts were installed on the sash, axle (3) and hook (2) can rotate within the specific limits.After one end of hook (2) held axle (3), outstanding small pieces were in order to limit the limit that hook (2) counterclockwise rotates; The other end of hook (2) is one and has the arm that protrusion is mentioned that the forward position of mentioning is an inclined-plane.Respectively there is a hole that is used to install at the two ends that hung parts (1), and the middle part projection of being hung parts (1) is so that tangled.Being hung parts (1) is installed on the window frame.Two holes on the stator (4) are used for the rotational hook parts are installed in sash.In the use, when sash close fashionable, the rotational hook parts that are installed on the sash are hung component movement to quilt, when the inclined-plane in forward position mentioned of hook (2) is run into when being hung parts (1), hook (2) clockwise rotates, and mentioning of (2) of hook upwards lifted, and crosses up to mentioning of hook (2) and is hung parts (1), rotate counterclockwise to tangle at action of gravity lower draw-bar (2) and hung parts (1), entered lock-out state.Present embodiment is applicable to the window of pushing open to outdoor.

Fig. 3 and Fig. 4 show another embodiment of the present utility model, are applicable to the window that draws back to indoor.Fig. 4 is the A-A sectional view of Fig. 3.The rotational hook parts of present embodiment are made up of hook (5) and spring (6).By hanging parts are wood screws (7).Wood screw (7) is installed on the sash.Wood screw (8) will be linked up with (5) and be installed on the window frame, and wood screw (8) also is the axle that hook (5) rotates simultaneously.Two pawls of spring (6) are hung on hook (5) and the dog screw (9), make hook (5) be subjected to a power that clockwise rotates around screw (8).The limit that dog screw (9) restriction hook (5) clockwise rotates.In the use, when sash close fashionable, after being installed in wood screw (7) on the sash and running into the inclined-plane of hook (5), hook (5) is rotated counterclockwise, enter the groove of hook (5) up to wood screw (7), hook (5) clockwise rotates under the effect of spring force, tangles wood screw (7) and enters lock-out state.Fig. 3 and the lock-out state that Figure 4 shows that present embodiment.Imaginary line is depicted as sash and window frame.

More than the explanation of two embodiment do not relate to beautifying of outward appearance, profile and surfacing can be adopted ornamental figure and color in force.

Claims (4)

1, a kind of rotational hook formula thumb-latch of keeping building window to close of being used to, form by the rotational hook parts with by the extension parts, the rotational hook parts that it is characterized in that rotational hook formula thumb-latch have a rotary part in addition at least, and an end of the hook in the rotational hook parts [2] is one and has the arm that protrusion is mentioned.

2,, it is characterized in that the forward position of mentioning of hook (2) is the inclined-plane according to the described rotational hook formula of claim 1 thumb-latch.

3, according to claim 1 or the described rotational hook formula of claim 2 thumb-latch, it is characterized in that rotational hook formula thumb-latch except that spring and rotating shaft all the other in addition parts all make by the metal sheet stamping parts.
