JPS5825117Y2 - Window door lift operation device for inward opening windows - Google Patents

Description

[Detailed explanation of the invention] There are many types of window structures, such as inward opening, outward opening, and sliding.In particular, in the case of an inward opening method in which the window door opens indoors, the window door opens when opened. There is a type that opens after being lifted slightly upwards from the closed position.

In other words, in the case of a window that swings outward, if a draining strip is installed on the lower frame of the window outer frame on the indoor side of the window door, then when the window door is closed, the lower sill of the window door will be above the Since it contacts the draining strip, it is convenient to position the window door when closing the window and prevent rainwater from entering the room at the same time.

However, when trying to create the same effect by installing such a draining strip on an inward-opening door, the opening direction of the window door is opposite to that of an outward-opening window, so the draining strip may not be able to open properly. It becomes an obstacle.

Therefore, it is necessary to provide a mechanism to rotate the window door after giving it enough lifting force to overcome the draining strip.

However, the hinge structure of such an inward-opening window naturally allows the window door to move up and down and rotate, so it has to be large in size. However, it has the disadvantage of being aesthetically unsightly.

Therefore, various hidden hinge structures have been proposed.

The present invention provides a lift operation lever device for such a hidden hinge, and in particular, when the window door is raised with the lift operation lever device, the raised posture of the window door is reliably maintained and its own weight is reduced. Try to provide something that can prevent you from falling.

Hereinafter, one embodiment of the present invention will be explained based on the drawings. Fig. 1 shows a front view of the indoor side of an inward opening window, and 1 in the figure shows the upper frame 1.
a, the window frame consisting of the lower frame 1b and the left and right side frames 1C91C surrounds the window opening, and the upper stile 2a, the lower stile 2b and the left and right sides are connected using hidden hinges to be described later on the window frame 1. A window door 2 consisting of vertical frames 2C and 2C is attached so as to be openable to the indoor side.

3 is the glass plate fitted into the window door 2, 4 is the window door 2 raised (
(when opened) and lowered (when closed); 5 indicates a handle;

Further, 6 is a draining strip provided on the lower frame 1b.

Hidden hinges are installed at three positions shown in arrows a, l), and c in FIG. .

In other words, the hidden hinge 7 at position a, as shown in FIGS. 2 to 4, has two vertical shaft rods 8 and 9 of the same length, one vertical shaft rod 10 that is shorter than these, The equiaxed rods 8, 9.1 are arranged so that the imaginary lines connecting each axis form a triangle.
Short sleeves 11 and 12 are fitted around the upper and lower ends of the two adjacent long shaft rods 8 and 9 of the 0, respectively, so that they can only rotate freely.

These sleeves 11 and 12 serve as stoppers to set the upper and lower limits of the window door (more specifically, the lifting shaft cylinder described below), and the sleeves 11 and 12 at the upper and lower ends respectively touch the joint plates 13 and 14. are integrally connected via.

Also, sleeves 11.11, 12.1 are attached to these shaft cylinders 8 and 9.
The lifting shaft cylinders 15 and 16 are respectively fitted between the two shafts with a slidable range corresponding to the stroke h for lifting the window door, and both shaft cylinders 15 and 16 are also integrally connected via the joint plate 17. It is configured so that it can be raised and lowered at the same time.

Furthermore, sleeves 18 and 19 are formed extending from the upper and lower ends of the elevating shaft cylinder 16 of the elongated shaft rod 9 located at the right angle of the triangle, and are rotatable relative to the remaining short shaft rod 10. The hinge cylinder 20 is fitted onto the coaxial rod 10 using the gap between the sleeves 18 and 19 so as to be relatively rotatable and slidable.

Therefore, if the elevating shaft cylinders 15 and 16 are raised and lowered by external force, the hinge cylinder 20 will also move up and down accordingly.

Reference numeral 21 denotes a shift lever connecting member fixed to the lifting shaft cylinder 15, and the shift lever 22 of the lifting operation handle device 4 is interlocked therewith.

23 is a wing plate integrally fixed to the hinge cylinder 20.

In order to provide such a hidden hinge 7, a concave portion 32 is provided at the indoor corner of the side frame 1C, facing the vertical stile 2C, as shown in FIG.
is formed, and a hidden hinge 7 is housed within this recessed portion 32.

That is, the hidden hinge 7 has a screw insertion hole 25 in the frame surface 24 in the side frame concave portion 32 and penetrated in the joint plate 13, 14.
It is installed by screwing the screws 26 passed through it, and the wing plate 23 is attached to the window door frame 2.
Similarly, there are screw insertion holes 28 and screws 29 on the frame surface 27 on the C side.
It is fixed using.

In FIG. 4, numeral 30 denotes a rag cover for a concave portion extending from the vertical stile 2C, and numeral 31 denotes a rag cover for a concave portion extending from the side frame 1C.

In the concealed hinge having such a structure, when an external force from the lifting operation handle device 4 is applied to one lifting shaft cylinder 15 to raise it along the shaft rod 8 in the window-closed normal position shown by the solid line in FIG. Since the hinge cylinder 20 also rises together with the short shaft rod 10 via the shaft cylinder 16, the window door 2 also rises accordingly.

Therefore, if this rising amount is set such that the lower stile 2b can overcome the draining strip 6, the window door 2 can be moved from this rising position.
When the handle 5 is pulled toward the indoor side, the hinge cylinder 20 rotates around the shaft 10, so that the window door 2 is moved around the shaft 10.
This means that it can be opened to the indoor side centering on (the imaginary line position in Figure 4).

When closing the window door 2, the operation is performed in the opposite manner.

The hidden hinge installed at position C as seen by the arrow is the same as the one shown in Figs. 2 to 4 (however, the shift lever connection member 2
1) may be used, but a simplified configuration as shown in FIG. 5 may be used.

This hidden hinge 7' is fixed to the frame surface 24 of the gap 32 with screws passed through the screw insertion holes 33. A sleeve 35.35 integrally attached to the upper and lower ends of the section, a shaft rod 36 fitted into the sleeve 35.35 so as to allow relative rotation only, and a wing piece 37 fitted onto the shaft rod 36 so as to be rotatable and movable up and down. The lifting hinge cylinder 38, which is separated from the attached lifting hinge cylinder 38 and integrated with the vertical stile 2C via the wing pieces 37, rises along the shaft 36, allowing the window door 2 to rise, and the lifting hinge cylinder 38 38 rotates around the coaxial rod 36, the window door 2 is allowed to rotate toward the indoor side.

In other words, the shaft rod 36 is the two shaft rods 9 in the hidden hinge 7.
, 10 functions, and the lifting hinge tube 38 has a hidden hinge 7.
It functions as the hinge cylinder 20 and the lifting shaft cylinder 16 in .

The reason why the configuration is simplified in this way is that there is no need to directly receive input from the elevation operation lever device 4.

Next, the configuration of the lifting/lowering operation handle device 4, which is a feature of the present invention, will be described.

As shown in FIG. 6, this device 4 has a hollow casing 40 fixed to the side frame 1C with screws 39, 39, and the lower end of the hollow casing 40 has an opening 41. A base portion 43 of an operating handle 42 is fitted into the inside 41 and supported by a support shaft 44 so as to be movable up and down.

A pin 45 is horizontally installed on the handle base 43 at an eccentric position with respect to the support shaft 44, and a connecting rod 46 is attached to the pin 45.
The lower end of the rod-like body 47 is supported by a pin 48 at the upper end of the connecting rod 46 .

The upper end of this rod-like body 47 is always inserted into a vertical guide hole 49 provided in the upper part of the housing 40 .

Furthermore, the aforementioned shift lever 22 is attached to the rod-like body 47 with the screw 5.
1, and this shift lever 22 is integrated with the side frame 1.
It penetrates through the rag cover 31 of C and enters the concave portion 32, and in this state is interlocked and connected to the aforementioned shift lever connecting member 21.

For this interlocking connection, a short shaft 52 is supported on the shift lever connecting member 21 side, and this short shaft 52 is configured to fit into a retaining hole 53 at the tip of the shift lever.

Further, when the window door 2 is in the lowered position, the operating handle 42 is raised upward as shown by the solid line in FIG.
exists below the support shaft 44.

When the operating handle 42 is tilted downward around the support shaft 44 in the direction of the arrow, the pin 45 rotates around the support shaft 44 and passes through the support shaft 44 in the horizontal direction beyond the dead center 54. Advance upward.

Therefore, the continuous rod 46 presses the rod-like body 47, and the rod-like body 47 enters the guide hole 49, thereby moving upward while its movement locus is restricted to a straight line state.

Along with this, the shift lever 22 also rises, so that the above-mentioned external force acts on the elevating shaft cylinder 15, so that the window door 2 assumes the elevated position.

After lifting the window door 2 in this way, when you release your hand from the operating handle 42, the load on the window door 2 is transferred to the lifting operating handle device 4.
This may cause the operating handle 42 to rotate in the opposite direction, causing the operating handle 42 to unexpectedly descend again.

For this purpose, pins 55 are provided protruding from both sides of the connecting rod 46, and a spring 56 is wound around the pin 55 in a spiral manner. The spring force is always applied to the connecting rod 46 in the right direction in FIG.

When the pin 45 is rotated by the operating handle 42, the spring 5 will be tightened as the pin 45 approaches the dead center 54.
6 is further compressed in the direction of opening the legs (at the same time, the spring 56 slides together with the connecting rod 46), and when the pin 45 passes the dead center 54, it moves back (leg closing operation).

Since the force of the spring 56 acting on the connecting rod 46 in this imaginary line position in FIG. 6 is to further rotate the pin 45 in the same direction (clockwise in FIG. 6), the shift lever 22 and the rod-like body Although the dead weight of the window door 2 acts on the connecting rod 46 via the connecting rod 47, this dead weight is stopped by the spring 56, so that the rising posture of the window door 2 is reliably maintained.

Note that 50 in FIG. 6 indicates that the operating handle 42 is rigidly attached to the housing 4.
This is a rubber piece that prevents contact with zero.

In this way, the present invention is provided with a shift lever that passes through the casing outside the side frame and is interlocked with the hidden hinge in the recessed part. The lifting force of the shift lever associated with this is input to the window door through the hidden hinge, so that the window door can be reliably raised to open it, or conversely lowered to close it.

Moreover, the eccentric position of the operating handle and the shift lever are connected by a link, and when the pivot point between the operating handle and the link exceeds the toggle dead center above or below, the spring pressure in the direction of exceeding the toggle dead center is linked. Also, since it is equipped with a spring member attached to the operating handle, especially when the window door is raised, this raised position can be reliably maintained against the window door's own weight. It is useful because it allows you to maintain an open posture.
