[Problem that the invention attempts to solve]

In such a lift-down window, when assembling the glass door 3, the support shaft 9 has its base end attached to the glass door 3,
The tips will be connected to the slider 8, respectively.

In this case, the form in which the tip of the support shaft 9 is integrally connected to the slider 8 with screws or the like requires that the connection work be performed within the narrow vertical groove 5 because the slider 8 is pre-assembled in the vertical groove 5. First, the assembly workability becomes extremely poor.

As already mentioned, the configuration in which the tip end 9a of the support shaft 9 is fitted into the connection hole 10 formed in the inner surface 8a of the slider 8 for connection is advantageous in terms of simplified structure and ease of assembly. be. It is also effective to rotatably connect the slider 8 and the support shaft 9 in order to allow the glass door 3 to fall inwards.

However, when adopting a connection form in which the tip end 9a of the support shaft 9 is fitted into the connection hole 10 of the slider 8, the glass door 3 and the base end of the support shaft 9 are finally connected with screws, etc., as shown in FIG. must be integrated. During this work, the glass door 3 is heavy and there is not enough clearance between the glass door 3 and the vertical frame 4. Therefore, the assembly workability was still poor, and there was a problem that sufficient assembly strength could not be ensured. Furthermore, it was similarly difficult to remove the glass door 3 due to breakage of the glass or the like.

[Purpose of invention]

The present invention has been proposed to eliminate such conventional disadvantages.

The primary purpose of the present invention is to simplify the structure and improve assembly workability.

The purpose of the present invention is to facilitate not only the attachment but also the removal of a glass door from a sash.

An object of the present invention is to easily allow a glass door to be folded inwards.

[Means for solving problems]

In the present invention, as shown in FIGS. 2 and 3, sliders 8 are attached to the left and right vertical grooves 5 of the sash 1 so as to be movable up and down, respectively, and the sliders 8 are attached to the glass door 3.
are connected via a support shaft 9 extending from the left and right sides thereof, and the glass door 3 is supported by the slider 8 and the vertical groove 5
It is assumed that the window will be raised and lowered so that it moves up and down along the direction.

In concrete implementation, the above-mentioned counterbalance mechanism 7 is installed at the top of each vertical groove 5, and the lower end of the screw plate 13 is connected to the slider 8, so that the glass door 3 can be placed at any vertical height position. Make it possible to stop.

Furthermore, in the present invention, as shown in the principle diagram of FIG. 1, the support shafts 9 are supported on the left and right sides of the glass door 3 via mounting brackets 29 so as to be freely retractable and retractable. That is, the mounting bracket 29 has a sleeve 30 and a mounting piece 31, and the sleeve 30 is fixed via the mounting piece 31 so as to be in a horizontal position. The support shaft 9 is slidably inserted into the sleeve 30, and means is provided for holding the support shaft 9 in a position in which the tip end 9a of the support shaft 9 projects laterally outwardly from the open end 30a of the sleeve 30. The tip end 9a of the support shaft 9 is connected to the connecting hole 10 on the slider 8 side by fitting in the connecting hole 10 so as to be freely insertable and removable.
As a means for holding the support shaft 9 in the protruding position, it is conceivable to slide and bias the support shaft 9 with a spring member 36 so that the support shaft 9 always projects from the sleeve 30 as shown in the figure.

In implementation, it is desirable to rotatably fit and connect the support shaft 9 to the slider 8, so that the glass door 3 can be tilted inwards relative to the sash 1.

[Effect]

According to the present invention as described above, the mounting bracket 29 is fixed to the glass door 3 in advance, and the support shaft 9 is inserted into the sleeve 30 of the mounting bracket 29.
A slider 8 is attached to the vertical groove 5 of the slider. If the support shaft 9 is moved back toward the sleeve 30 from this state, the support shaft 9 will bring the entire glass door 3 into contact with the vertical frame 4 forming the vertical groove 5 of the sash 1, the protrusion of the slider 8, etc. The slider 8 can be guided so as to face the connection hole 19 of the slider 8 without interference. Next, when the support shaft 9 is made to protrude from the sleeve 30, its protruding tip 9a fits into the connecting hole 19 of the slider 8 from the inside, thereby connecting the slider 8 and the support shaft 9.

As described above, according to the present invention, the support shaft 9 is attached to the glass door 3 via the mounting bracket 29 so as to be freely retractable, so that even in a narrow space, the tip of the support shaft 9 can be prevented from coming into contact with other objects. By moving the support shaft 9 toward the sleeve 30 side so as not to cause any
0 can be fitted and connected very easily. Therefore, on-site assembly work efficiency can be significantly improved. According to a preferred embodiment of the present invention, in which the support shaft 9 is slidably biased to always protrude from the sleeve 30 by the spring member 36, after the tip end 9a of the support shaft 9 is opposed to the connection hole 10, the connection hole is 10 can be fitted even more conveniently.

Furthermore, simply by rotatably connecting the tip end 9a of the support shaft 9 to the connection hole 10 of the slider 8, the glass door 3 can be tilted inwards around the support shaft 9 relative to the sash 1. Moreover, even when it becomes necessary to remove the glass door 3 due to breakage of the glass of the glass door 3, etc., by retracting the support shaft 9 to the sleeve 30 side, the tip end 9a of the support shaft 9 can be removed. It can be easily removed from the connecting hole 10 of the slider 8, and the workability at this time is also good.

[First Embodiment] FIG. 2 shows the entire lift-down window to which the present invention is applied, and FIG. 3 shows the counterbalance mechanism 7, the details of which have already been described.

4 to 7 show a first embodiment of the present invention, and when looking at the slider 8 that is inserted into the longitudinal groove 5 of the sash 1 so as to be able to slide vertically, the slider 8 of the present invention has a self-lubricating property. It is made of a synthetic resin material such as polyacetal and has a rectangular block shape, and has a hole 16 passing through it vertically, and a boss 10a having a connecting hole 10 is integrally formed protruding from the inner surface 8a. Specifically, a cylindrical body 18 made of polyacetal is rotatably fitted into the boss 10a, and a connecting hole 10 is formed in the cylindrical body 18.

The through hole 16 has a lower end 16a as shown in FIG.
is formed with a large diameter and has a receiving surface 17, into which a connecting shaft 19 is rotatably inserted from below. This connecting shaft 1
9 has a tsuba 20 on the outer periphery near the lower end, and this tsuba 20
The upper surface of is received by the receiving surface 17 of the through hole 16,
This prevents the connecting shaft 19 from coming off above the slider 8.

In this attached state, the upper end 1 of the connecting shaft 19
The lower end of the threaded plate 13 of the counterbalance mechanism 7 described above is integrally connected to 9a.

The helical spring 15 of the counterbalance mechanism 7 includes:
In order to prevent the glass door 3 from falling when the glass door 3 is raised to the highest position, it is necessary to apply an initial spring pressure corresponding to the weight of the glass door 3. A spring pressure adjusting means 21 for this purpose is incorporated into the slider 8.

As this spring pressure adjusting means 21, the connecting shaft 19
can be rotated in the direction of winding and tightening the helical spring 15 via the screw plate 13 and the nut member 14,
Basically, any ratchet method that cannot be rotated in the tightening direction will suffice. In this regard, in the illustrated example, at the lower end of the slider 8, as shown in FIG. 5 and FIG.
The notch 22 spanning the corners of a and 8b is inserted into the through hole 16.
It is formed so as to communicate with the large diameter lower end portion 16a of. A locking piece 23 is fitted into this notch 22 so as to be horizontally swingable around a vertical shaft 24, and a spring 25 attached to the shaft 24 causes a tip acting portion 23a of the locking piece 23 to
6 and is biased to swing so that it always enters into the large diameter lower end portion 16a. The connecting shaft 19 has cam surfaces including an engaging surface 25 and a one-sided inclined surface 26 connected to the engaging surface 25 alternately formed at a phase shift of 180 degrees below the collar 20.
A split groove 27 is provided at the lower end of the connecting shaft 19.

In such a case, the elastic force of the spring 25 will cause the locking piece 23 to
The tip acting portion 23a of the connecting shaft 19 is always in abutment engagement with the lower end cam surface of the connecting shaft 19, and when the tip of a tool, for example, a screwdriver, is engaged with the split groove 27 and the connecting shaft 19 is turned in one direction, it is locked. The pieces 23 successively climb over the inclined surface 26 and tighten around the helical spring 15, and the locking piece 23
By abutting and engaging with the engagement surface 25, the return rotation of the connecting shaft 19 is prevented. With this, the spiral spring 15
Set the initial spring pressure to an appropriate value.

In this assembled state, the tip operating portion 23b of the locking piece 23 slightly protrudes from the inner surface 8a of the slider 8, and by manually operating the tip operating portion 23b, the locking piece 23 and Connection shaft 19
In this case, the connecting shaft 19 rotates back so that the spring pressure of the helical spring 15 is brought close to zero at once, and it is possible to cope with over-tightening of the helical spring 15.

The lower left and right sides of the glass door 3 are supported by sliders 8, 8 located within the vertical grooves 5, 5 via support shafts 9, 9. This support shaft 9 is attached to the horizontal frame 3a of the glass door 3 via a metal fitting 29.

This mounting bracket 29 is a horizontally long cylindrical sleeve 3.
A mounting piece 31 is integrally formed on the outer periphery of one end of the sleeve 30, and an internal thread is cut on the inner periphery of the other end of the sleeve 30, and a nut member 32 with a hole is fitted therein.

An insertion hole 35 is formed in the left and right end walls 33 of the horizontal frame 3a of the glass door 3, through which the sleeve 30 is inserted from the lateral outside, and the mounting piece 31 is screwed to the end wall 33, so that the sleeve 30 is horizontally inserted into the hollow interior. Fix it in the correct position.

The support shaft 9 is made of a circular metal pin, and the sleeve 3
A support shaft 9 is slidably inserted into the sleeve 30 from the outward open end 30a of the sleeve 30.

A spring member 36 made of a compression coil spring is interposed inside the sleeve 30 between the insertion side proximal end of the support shaft 9 and the nut member 32 as a means for holding the support shaft 9 in a protruding position. The spring member 36 slides and urges the tip 9a of the support shaft 9 to always protrude laterally outwardly from the outward open end 30a of the sleeve 30.

Thus, the tip 9a of the support shaft 9 is rotatably fitted into the connecting hole 10 of the slider 8, and the glass door 3 is now connected to the slider 8 via the support shaft 9. In addition, glass door 2 is the seventh
As shown in the figure, it can be tilted inwards around the support shaft 9.

A small diameter shaft portion 9b extends from the base end of the support shaft 9 as shown in FIG.
The small diameter shaft portion 9b is slidably inserted into the sleeve 30 so that the shaft end faces the outside, and the support shaft 9 is inserted into the open end 30 of the sleeve 30.
Member 3 that restricts contact so that it does not come out unexpectedly from a
8 is fixed to the shaft end of the shaft portion 9b.

During actual assembly, the counterbalance mechanism 7 and slider 8 are assembled into the left and right vertical grooves 5, and the two are connected in the manner described above. On the other hand, a mounting bracket 29 is fixed to the glass door 3, and a support shaft 9 is attached to it.

The glass door 2 is fitted into the sash 1 from the indoor side. At this time, a fingertip is placed on the tip end 9a of the support shaft 9, and almost the entire support shaft 9 is retracted into the sleeve 30 against the elastic force of the spring member 36. In this way, the tip 9a of the support shaft 9 is prevented from contacting and interfering with the projecting edge 4a on the indoor side (front side) of the vertical frame 4 of the sash 1, the boss portion 10a of the slider 8, etc.
The support shaft tip 9a is guided so as to face the connecting hole 19 of the slider 8. When the fingertip is removed from the support shaft tip 9a in this state, the support shaft 9, which had been retracted into the sleeve 30, receives the spring force of the spring member 36 and projects laterally outward in a horizontal state, and the support shaft tip 9a is directly fitted into the connecting hole 10 of the slider 8 and connected.
This fitted state is maintained by the spring force of the spring member 36, and the support shaft 9 will not come off unexpectedly from the connection hole 10.

Finally, the spring pressure of the helical spring 15 of the counterbalance mechanism 7 is adjusted by the spring pressure adjusting means 21 incorporated in the slider 8 to a value corresponding to the weight of the glass door 2, and the assembly is completed.

When it becomes necessary to remove the glass door 2 from the sash 1 due to breakage of the glass of the glass door 2, malfunction of the counterbalance mechanism 7, etc., the support shaft 9 is removed from the connection hole 10 of the sleeve 30. In this case, grasp the regulating member 38 through the opening (preferably the lower surface) of the lower stile 3b of the glass door 3, and
into the sleeve 30.

An operation knob 40 facing outward from the sleeve 30 through the
is provided so as to project from the outside, and the support shaft 9 can be moved inside and outside the sleeve 30, particularly inward, via the knob 40.

L-shaped locking portions 39a and 39b are formed at the proximal and distal ends of the slit 39, respectively, and the operation knob 40 is guided and locked in the proximal locking portion 39a (the spindle 9 is attached to the sleeve 39). state)
The tip 9 of the support shaft 9 can be held temporarily in this state.
After guiding a to face the connecting hole 10 of the slider 8, the temporary fixing is released. On the other hand, when the spindle tip 9a is fitted into the connection hole 10, the operation knob 40 is guided and locked to the tip side locking portion 39b to ensure that the spindle 9 does not come off from the connection hole 10, and The sliding movement of the support shaft 9 is locked to restrict the displacement of the entire glass door 3 in the left and right direction. Note that in this second embodiment, the spring member 36 can be omitted. The sleeve 3 is assembled with the locking portion 39a and the operating knob 40.
This is because means for holding the support shaft 9 in a protruding position from zero is configured.
