Description

[Detailed explanation of the idea] (Industrial application field) This invention relates to an opening/closing device for windows, doors, etc.

(Prior Art) A conventional sliding opening/closing device for windows, doors, etc. has a frame body, and two sliding doors, for example, are slidably supported by two guide paths provided above and below the frame body. ing. These two sliding doors are always in a parallel positional relationship no matter what position they are slid to.

(Problems to be solved by the invention) However, in the case of the above-mentioned conventional switchgear,
Even in the fully closed state, the two sliding doors are located parallel to each other, so the different levels of the sliding doors at this time impair the design of the opening/closing device.

(Means for solving the problem) This invention was made to solve the above problem, and its gist is (a) a frame body, and (b) a part of the frame body fixed to a part of the frame body. A fixed door, (c) a sliding door slidably supported by the frame, and (d) two spheres attached to the lower side of the sliding door apart from each other and rotatable in all directions to support the sliding door. (e) two pilots attached to the upper side of the sliding door and spaced apart from each other, and (f) a circular arc whose cross-sectional shape has approximately the same radius as the radius of the sphere, and installed on the lower side of the frame. (g) two guide grooves provided on the upper side of the frame body to guide the pilot, respectively; Each has a parallel part that is parallel to the fixed door, and bends from one end of this parallel part and extends so as to approach the extension line of the fixed door, so that in the fully closed state, the fixed door and the sliding door are on one plane. The opening/closing device is characterized in that the fixed door and the sliding door are arranged in parallel when the door is fully open.

(Function) When the opening/closing device is in the fully closed state, the fixed door and the sliding door are arranged on the same plane, and the appearance of the opening/closing device is streamlined, improving the design.

In addition, when opening the sliding door, the two wheels installed at the bottom of the sliding door roll along the guide groove, and the pilot installed at the top of the sliding door moves along the guide path, until the door is fully closed. The sliding door, which was on the same plane as the fixed door, comes to be located parallel to the fixed door during the opening operation, and remains parallel until the door is fully opened.

(Example) Hereinafter, an example of this invention will be described based on the drawings from FIG. 1 to FIG. 6.

In FIG. 1, reference numeral 1 denotes an opening/closing device, which in this embodiment is used as a window.

Two guide grooves 18 and 19 are provided in the lower horizontal frame 12. The cross-sectional shape of each guide groove 18, 19 is
As shown in Figures 4 and 5, it looks like a part of a circle. As shown in FIGS. 2 and 3, one guide groove 18 has the center vertical frame 15 as its starting end 18a and the left vertical frame 13 as its terminal end 18e. To be more specific, the guide groove 18 extends from the starting end 18a toward the indoor side (downward in the figure) so as to be perpendicular to the glass plate 30 (hereinafter, this part is referred to as the orthogonal part 18b), and further extends from the circular arc part 18d.
(hereinafter, this portion will be referred to as the parallel portion 18c). Further, the other guide groove 19 has a starting end 19a at the right vertical frame 14, and a terminal end 19e near the circular arc portion 18d of the guide groove 18. To explain in detail, the guide groove 19 has a starting end 19a.
It extends diagonally toward the indoor side (hereinafter, this portion is referred to as the diagonal portion 19b), and further extends parallel to the glass plate 30 (hereinafter, this portion is referred to as the parallel portion 19c). The diagonal portion 19b and the parallel portion 19c are connected via a connecting portion 19d. The parallel portions 18c, 19c of the two guide grooves 18, 19 are located on a straight line, but are not connected.

In addition, the upper horizontal frame 11 has the above-mentioned guide grooves 18 and 19.
Two guideways 20 with a U-shaped cross section are located symmetrically to the
is formed.

A sliding door 40 is slidably supported on the frame 10.

To explain in detail, the sliding door 40 has a frame 41,
The frame 41 has a protrusion 42 that protrudes toward the outside of the room.
It has a projecting portion 43 that projects further outward than the projecting portion 42 on the indoor side. A recess 42 a having a U-shaped cross section is formed in the protrusion 42 , and a glass plate 44 is fitted into the recess 42 a and fixed with a caulking material 45 .

Cars 50a,
50b is installed. As shown in FIG. 6, the car 50a has a base 51, and a substantially hemispherical recess 51a is formed at the bottom of the base 51. A large number of bearings 52 are arranged in this recess 51a,
Furthermore, a ball 53 (spherical body) is inserted. The ball 53 has approximately the same radius as the guide groove 18, and a portion thereof protrudes from a cover plate 54 attached to the lower side of the base 51. These bearings 5
2. The ball 53 is prevented from falling off by the cover plate 54, and the ball 53 is rotatable in all directions, that is, in all directions. Car 50b is also car 50
It has the same structure as a.

Further, at the upper part of both the left and right ends of the frame 41, there is a fourth
As shown in FIG. 5, a pilot 46 is fixed. A cylindrical pin 46a provided on the pilot 46 projects higher than the projecting portion 43 of the frame 41.

The car 5 mounted on the left side of the sliding door 40
0a is inserted into the guide groove 18 of the frame 10, the ball 53 of the wheel 50b mounted on the right side is inserted into the guide groove 19, and the pin 46a of the pilot 46 is inserted into each guide groove 20 of the frame 10. The sliding door 40 is attached to the frame 10 by being inserted into the frame 10.

In the above-described configuration, the fully closed state of the sliding door 40 of the opening/closing device 1 is as shown in FIGS. 2 and 4, and the glass plate 30 fixed to the frame 10 and the sliding door 4
The glass plate 44 fixed at 0 is arranged on the same plane. Therefore, the appearance of the opening/closing device 1 is streamlined and the design is improved.

In the fully closed state, the middle vertical frame 15, the upper horizontal frame 11, the lower horizontal frame 12, and the right vertical frame 14 of the frame 10 are
The packing 21 fixed to each flange 17 of the sliding door 4
This contacts the indoor end surface 43a of the overhang portion 43 of No. 0 and is sealed.

Next, when opening the sliding door 40, the left portion of the frame 41 of the sliding door 40 in FIG. 2 is pulled toward the indoor side. Then, the ball 53 of the left wheel 50a rolls toward the interior along the orthogonal portion 18b of the guide groove 18, and the left portion of the sliding door 40 moves toward the interior. On the other hand, the ball 53 of the right wheel 50b rolls slightly toward the indoor side along the diagonal portion 19b of the guide groove 19, causing the right portion of the sliding door 40 to move slightly toward the indoor side. That is, at the beginning of the opening operation, the sliding door 4
0 moves the left part of the sliding door 40 toward the interior side of the room from the middle vertical frame 15 while changing the positional relationship with the glass plate 30 from a straight line relationship to an oblique relationship.

Then, the ball 53 of the left wheel 50a rolls along the arc portion 18d of the guide groove 18, and the parallel portion 18
It leads to the entrance of c. During this time, the ball 53 of the right wheel 50b is still rolling on the diagonal portion 19b of the guide groove 19, and moves the right portion of the sliding door 40 further toward the indoor side.

After this, the left portion of the sliding door 40 is pulled to the left in FIG. Then, the ball 53 of the left wheel 50a rolls along the parallel portion 18c of the guide groove 18.
On the other hand, the ball 53 of the right wheel 50b is located in the guide groove 19.
It rolls on the diagonal part 19b toward the parallel part 19c. Then, when the ball 53 of the right wheel 50b starts rolling along the parallel portion 19c, the sliding door 40 and the glass plate 30 become in a parallel positional relationship. After this, each parallel portion 18c, 19c of the guide grooves 18, 19
Since both are provided parallel to the glass plate 30, the sliding door 40 moves while maintaining a parallel relationship with the glass plate 30, as shown in FIGS. 3 and 5, until it reaches the fully open state.

Here, in the opening/closing device 1 described above, since the ball 53 rolls and moves within the guide grooves 18 and 19 made of circular arc surfaces having approximately the same radius as the radius, the ball 53 moves in the circular arc portion 18d or the connecting portion 19.
Even when moving d, the sliding door 40 can be smoothly opened and closed.

That is, the ball 53 and the guide grooves 18, 19 are almost in point or line contact, and the contact width in the direction of movement of the sliding door 40 is very short.

However, if a rolling element other than the ball 53, for example a disc-shaped element, is used, the contact width between the rolling element and the guide grooves 18, 19 in the direction of movement of the sliding door 40 becomes longer. If the contact width is long, when the rolling element passes through the arcuate portion 18d or the connecting portion 19d, especially when passing through a sharply curved portion such as the connecting portion 19d, the rolling element and the guide grooves 18, 19 may interfere with each other at the front and rear ends of their contact ranges. As a result, the rolling elements cannot smoothly pass through the arc portion 18d or the connection 19d, and as a result, the sliding door 40 cannot move smoothly.

Incidentally, by increasing the width of the guide grooves 18 and 19 by the amount of interference described above, interference can be avoided and the rolling elements can be made to pass through the arcuate portion 18d or the connecting portion 19d relatively smoothly. . However, if the width of the guide grooves 18, 19 is increased, a gap is created in the indoor/outdoor direction between the rolling elements and the guide grooves 18, 19, which causes another problem in that the sliding door 40 wobbles in the same direction.

In this regard, in this opening/closing device 1, as described above, the ball 53 and the guide grooves 18, 19 are connected to the sliding door 4.
Since the contact length in the moving direction of 0 is short, the ball 53 can pass through the arcuate portion 18d or the connecting portion 19d without interfering, and therefore the sliding door 40 can be smoothly moved through the arcuate portion 18d and the connecting portion 19d. It can be moved. Moreover, since the radius of the ball 53 and the radius of the circular arc surface forming the guide grooves 18 and 19 are almost the same, the ball 53 is prevented from moving in the width direction (indoor/outdoor direction) by the guide groove 18. . Therefore, sliding door 4
0 can be prevented from wobbling in the same direction.

In addition, when closing the sliding door 40, the process proceeds in the opposite direction to the above-mentioned opening operation.

This invention is not limited to the above-mentioned embodiments, and various embodiments are possible.

(Effects of the invention) As explained above, according to this invention, when the opening/closing device is fully closed, the fixed door and the sliding door are arranged on the same plane, so that the appearance of the opening/closing device is streamlined. The design quality is improved as a result.

By providing guide grooves and guide paths in the frame for the two cars and two pilots installed above and below the sliding door, the sliding door can be placed on the same plane as the fixed door in the fully closed state. The opening action allows it to be positioned parallel to the fixed door. Furthermore, since the sliding door is provided with a sphere that can freely rotate in all directions, the sliding door can be smoothly opened and closed from the fully open position to the fully closed position. In particular, when the sphere passes through the bending part of the guide groove, there is no interference between the sphere and the guide groove, so the sliding door can be opened and closed smoothly, and the sliding door does not play indoors or outdoors. It is possible to prevent it from sticking.
