Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to a connecting device for operating rods for opening and closing windows in casement windows, sliding windows, single sliding windows, etc.

[Prior art]

In casement windows, double sliding windows, single sliding windows, etc., grooves with locking protrusions are provided in the longitudinal direction of the shoji stile, and a length for opening and closing the window is secured to the locking protrusions in the groove. A structure is adopted in which the operating rod of the shaku is inserted so as to be movable in the longitudinal direction and is connected to the operating rod of the opening/closing operation device attached to the frame of the shoji.

The shoji is opened, closed, or locked by operating the opening/closing device and moving the operating rod, which then activates the pins and locks attached to the stile of the shoji.

In order to connect the operating plate of the opening/closing device to the operating rod fitted into the groove of the stile in such a window, the two are overlapped and brought into close contact, and screws are screwed into the connection.

[Problems to be solved by this idea]

With this kind of structure, if the operating rod is not properly connected to the operating plate, the operating rod fitted into the groove will not move accurately in the longitudinal direction of the groove, causing the interaction between the groove and the operating rod. The sliding resistance between the opening and closing operation devices may make them heavy.

Furthermore, if the opening/closing operation device is incorrectly installed, the opening/closing operation may be made too heavy and the window opening/closing operation may not be performed smoothly.

Furthermore, the connection between the actuating plate and the actuating rod receives a biased load, which puts strain on the screws, which poses a problem in durability.

[Means for solving problems]

This invention is a connecting device that connects an operating rod that is movably housed in the longitudinal direction in a groove having a locking protrusion provided in the longitudinal direction of a shoji stile and an operating plate of an opening/closing operation device, The free end of the operating plate that protrudes vertically on the opening/closing operation device and the free end of the operating rod fitted into the groove of the stile are overlapped over a predetermined length, and a collar insertion hole is bored in the free end of the operating rod. A cylindrical part having a screw hole penetrated in the axial direction, and a connecting collar having a flange on the outer periphery of one end of the cylindrical part, the cylindrical part is loosely fitted into the collar insertion hole, and the actuating plate is assembled. and the length l of the cylindrical part of the connecting collar
is longer than the thickness t of the actuating rod, has a clearance c between the actuating rod and the actuating plate, and is connected so that the free end of the actuating rod can slide toward the free end of the actuating plate. This is a connecting device for an operating rod for opening and closing a window.

〔Example〕

This invention will be explained in detail below based on an embodiment shown in the drawings.

What is shown in the figure is a vertically rotating window, in which a shoji 3 is attached to a window frame in which upper and lower horizontal frames 1, 1 and left and right vertical frames 2, 2 are framed in a rectangular shape. The shoji 3 has upper and lower horizontal frames 4, 4 and left and right vertical frames 5, 5 assembled into a rectangular shape, and two glass plates 6, 6 are attached in parallel. A blind 7 is housed between the two glass plates 6, 6. The shoji 3 rotates with the left and right intermediate portions of the upper and lower horizontal frames 4, 4 pivoted on the upper and lower horizontal frames 1, 1, respectively.

Pulling parts 8a are attached to the upper and lower sides of the left and right vertical frames 5, 5 of the shoji 3, respectively, and the drawing parts 8a are
As shown in FIG. 8, it is fixed to an operating rod 9 housed within the frames 4 and 5. By moving the operating rod 9 up and down, the cam portion 10a of the pulling portion 8 engages with the cam portion 10b of the pulling portion 8b fixed to the vertical frame 2, and the shoji 3
When the shoji 3 is pulled in the closing direction, the periphery of the shoji 3 and the window frame are brought into close contact with the airtight material via an airtight material to improve airtightness and to lock the window.

A groove 11 that continues in the longitudinal direction is formed inside each of the upper and lower horizontal stiles 4, 4 and the left and right vertical stiles 5, 5. The groove 11 is provided with locking protrusions 12, 12 that are continuous in the longitudinal direction and protrude from the left and right sides of the opening. The operating rod 9 is a long plate-shaped body,
Leg pieces 13, 1 protruding toward one surface side at the left and right ends in the width direction
3 are formed continuously in the longitudinal direction. Leg piece 1
Step portions 14, 14 are provided on the proximal end side, which is opposite to the side where 3, 13 face each other. The operating rod 9 is movably fitted into the groove 11 of each frame 4, 5, and the locking protrusions 12, 12 are engaged with the step portions 14, 14 of the operating rod 9.

The operating rods 9 of each frame 4, 5 are connected by a connecting member 15. The connecting member 15 is disposed within a corner portion that is a connecting portion of the vertical and horizontal frames 5 and 4. The connecting member 15 is made of a flexible material such as an elastic sheet metal, chain, or wire, and is configured to accurately transmit the amount of movement of the operating rod 9 even at a corner.

One vertical stile 5 has a built-in opening/closing operation device 16. The opening/closing operation device 16 consists of a case 17, an operating plate 18, a pinion 22, and the like. Case 1
7 is formed into a U-shaped cross section by a sliding surface 17a and two parallel side surfaces 17b, 17b continuous from both ends of the sliding surface 17a. Inside the case 17 is a rectangular actuation plate 1 that can be moved by sliding against the sliding surface 17a.
8 is located. The upper and lower ends of the actuating plate 18 protrude from the case 17, and screw holes 20 each having a female thread are bored in the inner peripheral surface thereof. Holes 2 are provided at appropriate intervals vertically in the upper and lower intermediate portions of the actuating plate 18.
1 is drilled multiple times. Pins are placed between the two surfaces 17b, 17b of the case 17 above and below the sliding surface 17a to guide the sliding of the actuating plate 18. One side 1 of case 17
A pinion 22 is pivotally supported between 7b and 17b, and can be engaged with a hole 21 of the actuating plate 18. The pinion 22 is provided with a square hole. A handle 24 having a prismatic handle shaft 23 projecting thereon is attached to the surface of the vertical stile 5 at the location where the opening/closing operation device 16 is built-in, and the handle shaft 23 is inserted into the square hole of the pinion 22. ing. When the handle 24 is rotated, the pinion 22 also rotates, and the operating plate 18 moves up and down.

The window opening/closing operating rod connection device of the present invention is used to connect the operating plate 18 of the opening/closing operating device as described above and the operating rod 9 disposed inside the vertical stile 5 described above.

The operating rod 9 is divided into upper and lower parts, and a connecting collar insertion hole 25 is formed in each free end thereof.
A connecting collar 26 made of metal or synthetic resin is loosely fitted into the connecting collar insertion hole 25 . The connecting collar 26 has a cylindrical part through which a screw hole 28 is passed in the axial direction, and a flange part 27 that protrudes from the outer periphery of one end of the cylindrical part.
is provided. The length l of the cylindrical portion of the connecting collar 26 is longer than the thickness t of the operating rod 9. Also, the flange 27 of the screw hole 28 of the connecting collar 26
The inner circumferential surface of the end on which is formed is countersunk. When the cylindrical portion of the connecting collar 26 is fitted into the connecting collar insertion hole 25, the connecting collar 26 is loosely fitted so that it can move freely. The free end of the actuating rod 9 and the free end of the actuating plate 18 are overlapped by a predetermined length. The screw hole 2 of the connecting collar 26 loosely fitted into the connecting collar insertion hole 25 of the operating rod 9
A screw 30 is inserted through 8 and screwed into the screw hole 20 of the actuating plate 18.

Connected as above, connected collar 26
Since the length l of the cylindrical portion is longer than the thickness t of the operating rod 9, the difference becomes a clearance c that allows the free end of the operating rod 9 to slide toward the free end of the connecting collar 26.

Next, the effect will be explained.

When the handle 24 of the opening/closing operation device 16 is rotated, the actuating plate 18 is moved by a predetermined distance via the pinion 22. At this time, if the case 17 is not installed accurately in the frame 5, for example, if the case 17 is installed slightly shifted in the width direction of the frame 5, the case 17 is held between the actuating plate 18 and the actuating rod 9. If the clearance C is absorbed, the operating rod 9 can be smoothly slid along the groove 11 of the stile 5.
Therefore, the operating rod 9 is not subjected to local sliding resistance, and the handle operation does not become heavy.

Furthermore, there is a significant difference in temperature between winter and summer, which causes dimensional changes in the stile 5 itself, and the clearance C absorbs this dimensional deviation, allowing smooth steering operation as well.

Since there is no local sliding resistance, the screw 30 is not subjected to a large load and has good durability.

The connecting collar 26 is made of a cylinder, and the actuating plate 18 is rotatable around the connecting collar 26 of the actuating rod 9.
Even if the longitudinal directions of the two are not parallel and are slightly deviated and tilted, the connecting collar 26 rotates with respect to the connecting collar insertion hole 25 and can absorb the error. Therefore, in this case as well, the handle can be operated smoothly, and the screws are less likely to come loose during use.

The amount of movement of the actuating plate 18 is transmitted smoothly and accurately to the actuating rod 9, and as described above, the cam portion 10a of the pulling portion 8a fixed to the actuating rod 9 is transferred to the cam portion 10a of the pulling portion 8b fixed to the vertical frame 2. 10b. The shoji 3 is pulled together and brought into close contact with the periphery of the shoji 3 and the window frame through the airtight material, thereby increasing airtightness and locking the window.

This invention is not limited to the above-mentioned embodiments, but other embodiments described below can be considered.

This idea can be implemented with horizontal rotating windows, or with sliding windows or single-sliding windows that slide on rails. In this case, a concave groove and a locking protrusion are provided in the vertical stile, and an operating rod for operating a soundproof and airtight puller is inserted therein, and a handle is connected at the middle of the vertical stile. The present invention can be carried out regardless of the type of window as long as it is equipped with a combination of a window opening/closing operating rod and an opening/closing operating device.

The opening/closing operation device may be any device as long as it moves the actuating plate in the longitudinal direction; for example, it may be one in which the actuating plate is directly moved in the longitudinal direction by a lever.

The operating rod is not for moving the drawing part as described above, but may be set to operate the rotating shaft in the case of a window that can be tilted and rotated.

〔Effect of the invention〕

The connecting device for an operating rod for opening and closing a window according to this invention has a free end of an operating plate that projects upwardly and downwardly of an opening/closing operating device and a free end of an operating rod that is fitted into a concave groove of the frame overlapped over a predetermined length, A collar insertion hole is formed in the free end of the operating rod, and a connecting collar having a cylindrical portion through which a screw hole is passed in the axial direction and a collar portion on the outer periphery of one end of the cylindrical portion is loosely fitted into the collar insertion hole. The length of the cylindrical part of the connecting collar is l.
is longer than the thickness t of the actuating rod and has a clearance between the actuating rod and the actuating plate, and this clearance allows the free end of the actuating rod to slide toward the free end of the actuating plate. .

The clearance can absorb mounting errors in the opening/closing device, as well as deviations and irregularities caused by temperature changes, allowing smooth opening and closing without localized sliding resistance on the operating rod.

Since sliding resistance can be reduced, excessive force is not applied to the screws, resulting in good durability.
