Field of invention

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a handle for a lift type sliding window, and more particularly, to a handle for a lift sliding window that minimizes an excessive force on the handle when lifting and opening a large lift type sliding window.

Background of the Invention

In general, windows and doors are used as a general term for windows and doors in a building, and a frame in which the windows are installed is called a window frame. Among these windows, the swing doors, which are mainly used for veranda doors and other windows, are provided with window rollers equipped with guide rails, and are equipped with a window with rollers, and can be pushed through the guide rails to open and close windows, soundproofing, and insulation. There is a lift type sliding window that further improves the speed.

When the lift sliding window is rotated to open the window, the window is lifted a certain distance from the rail to open quietly and smoothly, and in the closed state, the window and the rail are in close contact to ensure airtightness, insulation sound insulation and watertightness. The formed windows are used for relatively large windows such as living room partitions and balcony windows.

The conventional lift sliding window is shown in Figure 1, the handle fixture of the handle bundle 101 is attached to the side of the door is rotatably coupled to the handle via the handle axis, the handle bundle 101 side Inside the rod housing 102 coupled to the drive rod 130 is installed to move up and down in conjunction with the rotation of the handle.

The lower part of the drive rod 130 is linked to the corner drive 105 is formed to surround the corner of the door, the corner drive 105 is a rear view through the connecting rod 108 (Bogie; 106 is fastened, and each of the corner drive and the bogie is provided with rollers 105a and 106a which rotate on the rail of the lower window frame 120.

On the other hand, a fixing bracket 107 is provided on the lower surface of the window, and guide shafts 105b and 106b formed in the corner drive 105 and the bogie 106 are inserted into the inclined long hole 107a formed in the fixing bracket. When the handle is rotated to open the window, the lock installed in the handle bundle is released, and the drive rod 130 is pulled up in conjunction with the handle, and thus the corner drive and the bogie connected to the drive rod. As the guide shafts 105b and 106b push up the inclined long hole of the fixing bracket 107 while the side is pulled to the side, the window frame coupled to the fixing bracket 107 is lifted a certain distance from the rail. Will be able to open the window.

In particular, as described above, the handle for opening the window is installed in the middle position of a large window has been desperately required durability and flexibility.

Accordingly, the present inventors have come to develop a structure of a handle that is installed in a lift sliding window having improved assembly convenience, durability, and flexibility.

It is an object of the present invention to provide a handle that is installed in a lift sliding window that is improved in convenience, durability and flexibility of assembly.

It is another object of the present invention to provide a handle for a lift sliding window which prevents the handle from being easily broken or a force of a user entering by lifting the large lift type sliding window by opening and closing the handle. There is.

The above and other objects of the present invention can be achieved by the present invention described below.

Detailed Description of the Invention

2 is an exploded perspective view of a handle installed in a lift sliding window according to the present invention, Figure 3a or 3b is a view showing a lift sliding window according to the present invention, Figure 3a is a front view of the handle, Figure 3b is a side view. .

Figure 4 is a side cross-sectional view showing only the tilting member of the lift sliding window according to the present invention.

The handles 1 installed on the lift sliding windows of the present invention are first and first symmetrically with respect to the pivot axis 3 for the handle 2 to be installed, as shown in Figs. 2 or 3A and 3B. 2 storage spaces (10, 10 ') are formed.

Guide grooves 11 are formed in the center toward each of the storage spaces 10 and 10 ', that is, the pivot shaft 3, and guide grooves 12 are formed on both sides of the guide grooves, respectively.

In addition, each of the first and second accommodating spaces 10 and 10 ′ and the guide groove 11 is provided with a tilting member 20 that elastically flows according to the rotational movement of the pivot shaft 3.

As shown in FIG. 4, the tilting member 20 has a protrusion 21 inserted into the guide groove 11, and a bearing insertion groove 21 a and oil O, in which a needle bearing B is mounted. The oil tank 21a to be received is formed, and is formed to extend in a wider area than the protrusion 21, and a plurality of elastic member inserting grooves 22a for inserting the elastic member 30 therein are formed, and The guide protrusion 22b for coupling to the guide groove 12 is formed of a protruding body 22.

For example, the plurality of elastic member insertion grooves 22a are formed at least two, two are formed symmetrically to the left and right, and three are formed to have a predetermined interval in the center, left and right.

In addition, a plurality of elastic members 30 are elastically installed in the plurality of elastic member insertion grooves 22a to control the linear movement of the tilting member 20 and return them to their original state.

At this time, the tension of the elastic member can be adjusted according to the depth of the elastic member insertion groove (22a), preferably the elastic member insertion groove (22a) formed on the left, right than the elastic member insertion groove (22a) formed in the center By forming the depth of the deeper) to install the elastic member 30, to maintain a constant balance of force during the steering wheel operation, the elastic member 30 is fixed to the elastic member insertion groove (22a) formed in the center By installing a fixing pin (31) to handle to improve the durability and flexibility when operating.

In addition, by forming a predetermined angle on the guide projection (22b) formed in the lower portion of the body, it is to improve the assembly ability that can be easily assembled without interference of the guide groove 12 when inserted into the storage space.

At this time, the guide groove 12 serves to prevent the separation of the tilting member 20 and to maintain the overall balance,

Meanwhile, a needle bearing B is installed between the tilting member 20 and the pivot shaft 3 to smoothly rotate the pivot shaft 3.

That is, a bearing B is installed in the bearing insertion groove 21a formed in the protrusion 21 of the tilting member 20, and an oil tank capable of storing oil O above the bearing insertion groove 21a. 21b is formed to form an oil film on the surface of the bearing, thereby reducing wear caused by continuous use, extending life, and being operated flexibly by the oil film.

In addition, the guide protrusion 22b formed on the lower portion of the tilting member 20 may serve as a needle bearing by the oil film of the oil (O).

4 is a tilting member 20, an elastic member 30, a needle bearing B, and the like, which are fixed by screws not shown on one side of the handle and installed in the accommodation spaces 10 and 10 'of the handle. It is a fixed plate to prevent the departure.

Therefore, the handle installed in the lift sliding window according to the present invention is installed and used in the lift sliding window as in the prior art, as shown in FIG.

As described above, the handle for a lift sliding window and door according to the present invention can obtain an effect of preventing the handle from becoming excessive when lifting and opening a large lift-type sliding window.

Simple modifications and variations of the present invention can be readily used by those skilled in the art, and all such variations or modifications can be considered to be included within the scope of the present invention.
