Referring to Figures 1 through 4, an embodiment of the spring type sash positioning device 1 of the present invention is adapted to be disposed in a window. In this embodiment, the window is exemplified by a lifting window 5, and includes a window 51 and a first sash 52 movable up and down relative to the window 51, but not in this type. The window is limited. The window 51 is a window frame in this embodiment, and the inner frame of a right side frame of the window 51 The surface is formed with four receiving holes 511 which are spaced apart and respectively located at different heights, so that the spring sash positioning device 1 can be inserted into one of the receiving holes 511 when the first sash 52 is pulled to different heights. The first sash 52 is positioned at a desired position. The number of the receiving holes 511 is not limited to four, and there may be more than four connecting holes 511, so that the first sash 52 can achieve more positioning, or only one receiving hole 511, and the connecting hole 511 Preferably, a top side frame adjacent to the window 51 is such that the spring sash positioning device 1 can be inserted into the through hole 511 when the first sash 52 is pulled to a fully open position (see FIG. 7). The position of the first sash 52. The holes 511 can also be formed on a left side frame of the window 51, and are not limited to a specific side frame. The first sash 52 includes a first window frame 521 and a socket 522 extending through the first window frame 521 and adapted for the spring sash positioning device 1 to pass through.

The spring type sash positioning device 1 comprises a sleeve 2, a locking pin unit 3, and a spring member 4. The sleeve 2 is adapted to be inserted into the insertion hole 522 of the first sash 52, and includes a tube body 21 defining a connecting space 22, an end formed at the tube body 21 and the socket space 22 a first opening 23 communicating with each other, a second opening 24 at the other end of the tube body 21 opposite to the first opening 23, a direction defining the first opening 23 and slightly facing the second opening 24 The turned over portion 25 and a slot 26 formed on the side of the tube body 21 along the longitudinal direction of the tube body 21 and connected to the first opening 23. The aperture of the first opening 23 is larger than the aperture of the second opening 24, and the aperture of the insertion hole 522 of the first sash 52 is between the aperture of the first opening 23 and the aperture of the second opening 24. The outer diameter of the tube body 21 is tapered from the first opening 23 toward the second opening 24, so that the sleeve 2 presents a left narrow right width shape in the illustration. It is worth mentioning that the effect of the shape is that the sleeve 2 is installed in the insertion hole 522, and the tube body 21 can be clamped and compressed by a clamp (not shown), and the tube is opened. The slot 26 on one side of the body 21 gives the tube body 21 a compressible space when the tube body 21 is squeezed, and the diameter of the first opening 23 connected to the slot 26 is also the tube body. 21 is temporarily smaller when squeezed, until it is slightly equivalent to the aperture of the jack 522, and then the sleeve 2 is inserted into the insertion hole 522, and the first window frame 521 is touched at the folding portion 25 to determine After the installation position of the sleeve 2, the clamp is loosened, and the tube body 21 is adjacent to the first opening 23 and is stretched and pressed against the insertion hole 522 because the clamping force of the clamp is reduced. 2 is stably stuck in the jack 522. Of course, if the resistance of the sleeve 522 to the sleeve 2 can be broken during installation, the sleeve 2 can be directly forced into the insertion hole 522, and the fixture can be omitted.

The latch unit 3 is movably disposed in the socket space 22 and includes a pull rod 31, and a latch 32 coupled to the pull rod 31 and movably extending or retracting into the tube body 21. The pull rod 31 has a shaft portion 311 passing through the second opening 24, a connecting portion 312 connected to one end of the shaft portion 311 for connecting the plug pin 32, and a connecting end of the shaft portion 311 and located at the other end. The limiting portion 313 outside the sleeve 2 and a handle portion 314 connected to the limiting portion 313 for the user to grip. The spring member 4 is disposed on the sleeve portion 22 and sleeved on the shaft portion 311 of the latch unit 3, and the two ends abut against the tube body 21 and the latch 32 respectively, so that the latch 32 is constantly exposed. Moving in the direction of the tube body 21.

5 to 7, the locking pin unit 3 is switchable relative to the tube body 21 between a locking position as shown in FIG. 5 and an unlocking position as shown in FIG. 6. In detail, when the locking pin unit 3 is located in the locking position, the pin 32 is pushed by the elastic force of the spring member 4 to extend out of the tube body 21 through the first opening 23, and is inserted into the connection of the window 51. Hole 511. The limiting portion 313 is interlocked by the shaft portion 311 connected to the latch 32 to abut the sleeve 2 adjacent to the second opening 24. By using the through hole 511 The movement space around the pin 32 is restricted, further restricting the first sash 52 from moving relative to the window 51. When the user wants to adjust the opening size of the lifting window 5, the handle portion 314 of the pull rod 31 can be gripped and pulled away from the connecting hole 511, and the latch 32 will follow the pulling rod 31 to gradually extend. The first sash 52 is located in the unlocked position, and the first sash 52 can be positioned relative to the window. The latch 511 is retracted into the tube body 21 until the latch 32 completely extends out of the receiving hole 511. The 51 is moved for the user to adjust the height of the first sash 52, and the locking pin unit 3 is aligned with one of the other three receiving holes 511. When the user moves the pull rod 31 in a direction away from the connecting hole 511, the spring member 4 is compressed and deformed by the tube body 21 and the plug 32 to accumulate an elastic restoring force. When the user adjusts the first sash 52 to the desired position, the grip of the handle portion 314 can be released, and the elastic restoring force accumulated by the spring member 4 will be released and pushed against the latch 32 at this time. Corresponding holes 511 limit the position of the first sash 52 to achieve the function of sash positioning.

Referring to FIG. 8 , in other embodiments, the window may also be a pair of windows 6 and include a window frame 61 , and a first window sash 62 and a window pivotable relative to the window frame 61 . And in this embodiment, the window is a second sash 63 corresponding to the first sash 62. The second sash 63 includes an access hole 631. The spring type sash positioning device 1 is disposed on the first sash 62 and corresponds to the receiving hole 631 of the second sash 63. When the user wants to close the pair of windows 6, the pull rod 31 can be pulled to retract the bolt 32 into the sleeve 2, and the first window sash 62 and the second window sash 63 are pivoted to close the window frame 61. The first window fan 62 and the second sash 63 can be easily locked by inserting the latch 32 into the contact hole 631 by the spring member 4.

In summary, the spring type sash positioning device 1 of the present invention is provided with a spring member 4 in the sleeve. 2 is sleeved on the locking pin unit 3, so that the locking pin unit 3 is constantly moving toward a locking position. When the user wants to open and close a lifting window 5, only the locking pin unit 3 needs to be moved to an unlocking position first, and When the first sash 52 is pushed to a predetermined position, the locking pin unit 3 is automatically driven to the window 51 by the spring member 4, so that the first sash 52 cannot move relative to the window 51, saving the user. The time when the lock pin unit 3 is to be pulled back and forth; in addition, when the user wants to close and lock the pair of windows 6 , the latch 32 of the lock pin unit 3 disposed on the first window sash 62 can also be inserted into the second The opening 631 of the sash 63 achieves the function of sash positioning, so the object of the present invention can be achieved.

However, the above is only the embodiment of the present invention, and the scope of the invention is not limited thereto, and all the equivalent equivalent changes and modifications according to the scope of the patent application and the patent specification of the present invention are still The scope of the invention is covered.
