Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention is suitable for use in partitioning office space and the like, and in particular, has an opening in its panel or door portion. The present invention relates to a partition device.

[Prior Art] There is known a partition device in which a panel-shaped portion or a door is provided with a window-shaped opening or a large opening over substantially the entire area of the panel. Conventionally, in this type, a transparent glass plate is attached to the opening, a so-called blind is arranged inside the opening, and the other space partitioned can be seen by operating the blind. It is designed so that it can be put in a blind state or cannot be seen through. However, this type of blind has a problem that dust is likely to adhere to it and is difficult to clean. Therefore, recently, there has been developed one in which glass plates are arranged in double and the above-mentioned blinds are arranged between the glass plates. Also,
Another method has been developed in which a liquid crystal panel is used instead of a glass plate, and the light shielding state can be adjusted by changing the voltage application state.

[Problems to be Solved by the Invention] However, when a blind having a large number of blades is housed in a double glass, there is a problem that repair is difficult when the blades are entangled with each other to cause malfunction.

Further, since the liquid crystal type is difficult to manufacture at present, a large area type is expensive. Moreover, there is an inconvenience that the power supply is indispensable for adjusting the light-shielding state and cannot be used in the event of a power failure.

The present invention can solve the above problems,
An object of the present invention is to provide a partition device that is easy to clean, has a simple structure, is hard to cause a failure, and can finely adjust the light-shielded state without supplying power.

[Means for Solving the Problems] The present invention employs the following configuration in order to achieve the above object.

That is, the partition device of the invention according to claim 1 of the present application is a partition main body having an opening, a pair of glass plates overlappingly arranged in the opening, and an operation of relatively displacing the glass plates in the plane direction. And a transparent portion and an opaque portion are alternately formed on one glass plate at a predetermined pitch, and on the other glass plate, a transparent portion and an opaque portion are formed at the same pitch as one glass plate. The operation mechanism has a rotating shaft supported by the partition main body so as to be able to rotate in the forward and reverse directions, a crank pin eccentrically mounted on the rotating shaft, and a fixed part on the edge of the glass plate. The side shaft member is provided with a long hole into which the crank pin is vertically slidably fitted, and the rotary shaft is configured to be operated from the outside. , Rotate the rotation shaft at a predetermined rotation position. It is characterized by being provided with a lock mechanism for locking.

Further, the partition device of the invention according to claim 2 of the present application is a partition main body having an opening, a pair of glass plates overlappingly arranged in the opening, and an operation of relatively displacing these glass plates in a plane direction. And a transparent part and an opaque part are alternately formed on one glass plate at a predetermined pitch, and on the other glass plate, the transparent part and the opaque part are opaque at the same pitch as one glass plate. The operation mechanism has a rotating shaft supported by the partition main body so as to be able to rotate in the forward and reverse directions, a crank pin eccentrically mounted on the rotating shaft, and a fixed part on the edge of the glass plate. A vertical groove provided on the side frame member provided so that the crank pin is slidably fitted in the vertical frame, and the rotary shaft is configured to be rotationally operated from the outside. , Lock the rotation shaft at a predetermined rotation position Characterized in that provided because of the locking mechanism. In this specification, the transparent portion means a portion having such a transparency that an image of a distant object can be visually recognized from the opposite side, and it does not matter whether it is colored or non-colored. The opaque portion means a portion having a property that an image of a distant object cannot be seen from the opposite side. Therefore, it is not limited to one that completely blocks light, but includes one that allows light to pass through, such as frosted glass and shoji paper, but makes it impossible to accurately view the image on the opposite side.

The partition wall main body includes a partition panel, a door, or a frame body composed only of a frame material. However, the opening is not limited to the window-like part partially formed in the partition panel, the door or the like, and may be a large area formed in the entire area inside the frame.

The transparent portions and the opaque portions can be arranged in vertical stripes, horizontal stripes, or diagonal stripes. Alternatively, they may be arranged in a checkered pattern.

When the transparent portion and the opaque portion are arranged in a vertical striped pattern, a diagonal striped pattern, or a checkered pattern, the objective can be achieved by moving both glass plates relatively in the left-right direction. When the transparent portion and the opaque portion are arranged in a horizontal striped pattern, a diagonal striped pattern, or a checkered pattern, both glass plates can be relatively moved in the vertical direction to achieve the purpose. . Furthermore, when the transparent portion and the opaque portion are arranged in a diagonal stripe pattern or in a checkered pattern pattern, both glass plates may be relatively moved in a diagonal direction.

Both glass plates may of course be provided so as to be movable with respect to the partition main body, but in order to improve the sealing property, one glass plate is fixed to the partition main body and the other glass plate is fixed. Is preferably held movably in the partition body.

When it is desired to move both glass plates in the vertical direction with a small operation force, it is preferable to connect both glass plates by a slippery interlocking mechanism.

To surely form the opaque portion on the glass plate, it is preferable to use frosted glass treatment. In this case, in order to make cleaning particularly easy, it is preferable to arrange the surfaces of both glass plates that have been subjected to frosted glass treatment on the inner surface side.

As another means for forming the transparent portion and the opaque portion, there is a method of sticking a synthetic resin film having a transparent portion and an opaque portion to a glass plate material.

When it is desired to avoid direct contact between the glass plates, it is preferable to place the above-mentioned synthetic resin film between the glass plates.

As a locking mechanism with a simple structure, a holding hole recessed in the outer periphery of the rotating shaft, a protrusion / contractor accommodated in the retaining hole so that it can be retracted / retracted, and the protrusion / contraction member are elastically biased in the outer diameter direction. A spring that is elastically mounted on the inner peripheral surface of the bearing member that holds the rotating shaft, and that engages with the projecting member when the rotating shaft is recessed in the inner peripheral surface of the bearing member and the rotating shaft rotates to a predetermined position. One having an engaging recess is mentioned. In this case, it is preferable that when the handle is attached to the rotary shaft, the protrusion and sinker is pressed by the handle and can be retracted into the holding hole.

The operation mechanism is not limited to the one described above, and for example, a rotating shaft supported on the partition body side so as to be able to rotate forward and backward, a pinion attached to this rotating shaft, and a frame member fixed to the edge of the glass plate. It may be provided with a rack that is fixed and meshes with the pinion.

Instead of the glass plate, a transparent synthetic resin plate material may be used.

[Operation] According to such a configuration, in a state where the transparent portion of one glass plate and the opaque portion of the other glass plate overlap each other, a blind state in which one space cannot see through the other space Become. When both glass plates are moved relative to each other from this state, the overlapping area of the transparent part of the one glass plate and the transparent part of the other glass plate gradually increases, and the state on the other side can be visually recognized. . Then, in the state where both transparent portions are overlapped, the visibility is the best.

The above-mentioned relative movement of both glass plates is achieved by externally rotating the rotary shaft of the operating mechanism. That is, when the rotary shaft of the operating mechanism is rotated, the crank pin that engages with the long hole or the vertical groove provided in the side frame member is eccentrically attached to the rotary shaft, so that the crank pin has the long hole ( It moves in the direction of rotation of the rotating shaft while sliding vertically in the vertical groove). As a result, the side frame member moves in the rotation direction, and the glass plates overlap with each other. Therefore, the relative displacement of both glass plates can be changed only by rotating the rotating shaft, and the light-shielding state can be finely adjusted. Further, since the rotating shaft is provided with the lock mechanism, the rotating shaft can be locked at a predetermined position, and the adjusted light blocking state can be held in a stable state.

The same applies when a synthetic resin plate material is used instead of the glass plate.

[Embodiment] An embodiment of the present invention will be described below with reference to FIGS. 1 to 12.

The partitioning device of this embodiment is used, for example, when partitioning a room from a room in an office, and FIG. 1 is a front view of the partitioning device viewed from the inside of the partition in a partition state.
FIG. 2 is a plan view of the same. As shown in both drawings, this partition device is provided with a plurality of partition bodies 1 each having an opening 11 for mounting glass. The glass plates 2 and 3 are superposed on each other, and the other partition walls 41,
It is designed to be used with 42, 43 etc. connected in the plane direction.

More specifically, the partition main body 1 has a panel-like shape, and as shown in FIG. 3, a core material 12 that forms a window-shaped opening 11 between the cross rails 12a and 12b, and the core material 12 of the core material 12. It is composed of a face plate 13 attached to the surface, an outer window frame 14 and an inner window frame 15 fixed along the opening edge of the core material 12. Then, the peripheral edge portion of the glass plate 2 is closely adhered to the inner surface of the outer window frame 14 via the sealing material 16a and the fastener 16b (hereinafter, this glass plate 2 is referred to as "fixed glass plate"). On the other hand, as shown in FIGS. 3 and 4, the glass plate 3 to be superposed on the fixed glass plate 2 has frame members 31a, 31b, 31c mounted on the peripheral edge thereof, and the lower frame member thereof. A wheel 32 is pivotally mounted on the lower surface of 31a, and a guide groove 33 is provided on the upper surface of the upper frame member 31b along the surface direction. Then, an L-shaped metal fitting 16c is fastened to the lower surface of the horizontal rail 12a of the core material 12, the guide groove 33 is engaged with the L-shaped metal fitting 16c, and an L-shaped metal fitting is attached to the upper surface of the horizontal rail 12b of the core material 12. 16d is fastened and the wheel is placed on the L-shaped metal fitting 16d.
32 is mounted so that it can roll. Thereby, the glass plate 3
Can slide in the surface direction (hereinafter, this glass plate 3 is referred to as "movable glass plate").

On the other hand, as shown in FIG. 5, on one side surface of the fixed glass plate 2, transparent portions 2a and opaque portions 2b are alternately arranged at a predetermined pitch to form a vertical stripe pattern and face each other. On one side surface of the movable glass plate 3, the transparent portion 3a and the opaque portion are formed at the same pitch as in the fixed glass plate 2.
3b and 3b are alternately arranged to form a vertical stripe pattern. The materials of the glass plates 2 and 3 are used as they are for the transparent portions 2a and 3a, and the opaque portions 2b and 3b have a certain light-shielding property (for example, an image on the other side can be visually recognized through the frosted glass treatment). Impossible). Although the repeating pitch in this embodiment is based on the virtual reference line p shown in FIG. 11, the width dimension d ₁ of each of the opaque portions 2b and 3b on both glass plates 2 and 3 is the virtual reference line p. Interval l
The width dimension d ₂ of each transparent portion 2a, 3a is set to be slightly narrower than the interval 1 of the virtual reference line p.

The movable glass plate 3 can be slid leftward and rightward by the operation mechanism 5 shown in FIGS. 4 and 6 to 9. This operation mechanism 5 is the inner window frame.
A rotary shaft 52 rotatably and rotatably supported on the side frame member 15a of the shaft 15 through a bearing member 51, a crank pin 54 mounted on an eccentric part of the rotary shaft 52 through an arm 53, and a movable glass. A long hole 55 formed in the side frame member 31c of the plate 3 and into which the crank pin 54 is vertically slidably fitted. A nut member 52a fixed to the rotary shaft 52 is externally attached to a claw portion 56a of the handle 56.
By engaging with, the rotational operation force of the handle 56 can be transmitted to the rotary shaft 52.

In addition, the rotary shaft 52 of the operating mechanism 5 is CL
A lock mechanism 6 is provided for locking at the OSE position and the OPEN position (see FIG. 7). This lock mechanism 6
As shown in FIG. 6 and FIG. 8, a holding hole 61 is provided in the outer periphery of the rotary shaft 52, a pin-shaped projecting / contracting member 62 housed in the holding hole 61 so as to project and retract, and A spring 63 that elastically urges the protrusion / depression element 62 in the outer diameter direction to elastically mount on the inner peripheral surface of the bearing member 51, and a rotary shaft that is recessed on the inner peripheral surface of the bearing member 51.
When 52 is rotated to the OPEN position (and the CLOSE position), it engages with the projecting and retracting member 62 and locks the projecting and retracting member 62 in that position. Engagement recess 6
4b) and. Then, with the handle 56 attached to the rotary shaft 52, the locking state can be released by pressing the projecting recess 62 with the claw portion 56a and retracting it into the holding hole 61. There is.

With such a configuration, when the movable glass plate 3 is slid through the rotation operation of the handle 56, the movable glass plate 3 is relatively displaced with respect to the fixed glass plate 2, and as a result, the light shielding state is changed according to the offset position. It becomes possible to change. That is, when the operating state is in the CLOSE state shown in FIG. 7, the transparent portion of the fixed glass plate 2 as shown in FIG.
2a and the opaque part 3b of the movable glass plate 3, and the opaque part 2b of the fixed glass plate 2 and the transparent part 3a of the movable glass plate 3 are set so that they can overlap with each other. It is possible to create a blind state in which the space between the two sides is optically blocked with a certain effect and the other party's space cannot be seen through. At this time, since the settings are such that d ₁ >l> d ₂ , both opaque portions 2b and 3b are partially overlapped,
The leakage of light from the gap is effectively prevented, the opacity is further strengthened in the overlapping portion, and a vertical stripe pattern of light and shade is produced, and a design effect is also exhibited.
From this state, when the handle 56 is rotated in the OPEN direction shown in FIG. 7, the movable glass plate 3 slides in the direction indicated by the imaginary line in the figure, and together with this, the opaque portions 2b and 3b of the glass plates 2 and 3 are also moved. The overlapped area between the glass plates gradually decreases, and after it disappears, the glass plates 2, 3
The overlapping area between the transparent portions 2a and 3a is increased.
Therefore, at the stage where the handle 56 is operated by 45 °, for example,
As shown in FIG. 11, the two glass plates 2 and 3 are relatively shifted by a half pitch to be in a half-opened state, and a slight translucent portion is generated between the two so that the other space can be visually recognized from the translucent portion. Become. When the handle 56 is further operated from this state, when the glass plate 2 and 3 are rotated 90 ° to the OPEN position in FIG. 2a and 3a are overlapped with each other and opaque portions 2b and 3b are overlapped with each other, and the area of the translucent portion is maximum and the best visibility is obtained. Also,
If the reverse operation is performed from this state, the light-transmitting portion is gradually reduced, and eventually the blind state is obtained.

Then, in the partition device provided with such a partition main body, the blind function is performed by both the glass plates 2 and 3 themselves, and they are arranged so as to be located on the opposite surface side of the both glass plates 2 and 3 of the ground glass surface. Therefore, compared with the conventional one in which a blind having a large number of blades is arranged on the front surface of the glass plate, it is particularly easy to get dirty and difficult to clean, and the blind is placed between the double glass plates. There is no place where they are intertwined with each other as compared with the conventional one in which is charged. For this reason, it is possible to easily complete the cleaning simply by wiping the windows from the inside and the corridor side, and it is possible to obtain extremely good operability without causing inconvenience such as malfunction. Becomes Further, compared with a liquid crystal panel or the like, it is much cheaper in cost, and there is no inconvenience that the operation is affected by the power supply state. Therefore, this partition device can be put to practical use as a device having a convenient blind function.

Note that the configuration of each unit is not limited to the illustrated example, and various modifications can be implemented. For example, in the above-mentioned embodiment, both glass plates 2 and 3 had a vertical stripe pattern, but as shown in FIG. 13, the transparent portions 1 are alternately arranged on the glass plate 102 at a predetermined pitch.
02a and the opaque portion 102b are arranged in a horizontal stripe pattern, and a transparent portion 103a is formed on the inner surface of the glass plate 103 facing the same with the same horizontal stripes.
Alternatively, the opaque portions 103b may be arranged so that they are relatively displaced in the vertical direction. According to such a configuration, basically the same operational effect can be obtained by only changing the direction of the striped pattern and the direction of operation as compared with the above embodiment (see FIGS. 10 to 12). Corresponding to the state). In this case, as shown in Fig. 14 (a), both glass plates
102 and 103 are movable, and these are connected to a pulley 104a and a wire 104b.
If the suspension type interlocking mechanism 104 having the above is suspended and supported, the operability can be easily improved. When the one glass plate 102 is fixed, the other glass plate 103 is attached to the weight 105 (see FIG. 2B) or the spring 10.
It is also effective in terms of operation to balance them so that they can be easily moved by using 6 (see (c) of the same figure). Further, as another striped pattern, as shown in FIG. 15, a transparent portion 202a and an opaque portion 202b are alternately arranged on the glass plate 202 at a predetermined pitch.
Are arranged in a diagonal striped pattern, and a transparent portion 203a and an opaque portion 20 are formed in the same diagonal striped pattern on the inner surface side of the glass plate 203 facing this.
3b and 3b may be arranged so as to be relatively displaced in an oblique direction. In this case, the operation mechanism shown in FIG. 16 is simple and convenient. In the illustrated example, when the glass plate 202 is fixed and the glass plate 203 is movable, for example, the rack 204 fixed to the lower frame member 203a of the glass plate 203 is shown.
And a pinion 205 that meshes with the rack 204, and a pair of pins 206 that horizontally project from the upper frame member 203b of the glass plate 203.
And a slanted elongated hole 207 fitted to these pins 206, the pinion 205 and the elongated hole 207 are provided on the partition main body side, and the pinion 205 is rotated from the outside via the rotary shaft 206. Be prepared to transmit operating force. According to this, by rotating the pinion 205, the glass plate 203 can be automatically guided obliquely in the vertical direction. In addition, the blind function obtained in this way is divided into the blind state shown in FIG. 17, the half open state shown in FIG.
In the fully opened state shown in FIG. 19, it is possible to obtain the same visual effect as that of FIGS. 10 to 12 in the above embodiment. In addition, this product has a utility value as it has a different design from the above-described embodiment in terms of design. Furthermore, if it is desired to further elaborate on the design while providing the required visual effect, for example, as shown in FIG. 20, the glass plate 302 is provided with transparent portions 302a and opaque portions 302b alternately at a predetermined pitch. Arranged in a checkered pattern,
Arranging a transparent portion 303a and an opaque portion 303b having a similar checkerboard pattern also on the inner surface side of the glass plate 303 facing this,
It is also effective to make relative displacement in the left-right direction. According to this, in the blind state shown in FIG. 21, the half open state shown in FIG. 22, and the fully open state shown in FIG. 23, beautiful pattern patterns can be produced. In the figure, the aspect ratio a / b of the transparent portions 302a and 303a forming a checkerboard pattern is set to 1, but by setting both dimensions a and b so that the values are other than 1, checkerboard patterns of various shapes Can be obtained. In addition to these, various patterns can be realized.

Further, in the above-described embodiment (see FIG. 7), the side frame member 31c
In addition, a long hole 55 that fits vertically slidably with the crank pin 54 is provided. Instead of the long hole 55, the side frame member 31
If a vertical groove (not shown) is provided along the longitudinal direction of c, the rotary shaft 52 can be attached at a position where operation is easiest. Further, although the operating mechanism 5 of the above-described embodiment is as shown in FIG. 6, in place of the operating mechanism 5, as shown in FIG. The shaft 402, the pinion 403 mounted on the rotating shaft 402, and the rack 405 fixed to the lower frame member 4040a of the glass plate 404 and meshing with the pinion 403 may be used. Alternatively, in the above-described embodiment (see FIG. 8), the engaging recesses 64a and 64b of the lock mechanism 6 are located at two positions orthogonal to the rotary shaft 52, and are provided at a total of four positions. As shown in FIG. 28, a simple type in which engaging recesses 501 to 504 are provided only at two positions with respect to the rotating shaft 552 may be used. In this case, it is particularly preferable to select the position shown in FIG. 27 or FIG. 28, and the lock function for the rotary shaft 552 when the glass plate can slide left and right can be effectively enhanced.

In addition to these, the partition main body is used as a door to provide a window-shaped opening, or the partition main body is used as a frame to make the entire area inside the opening, and instead of performing ground glass treatment, transparent and opaque parts are used. By attaching a synthetic resin film having and to a glass plate material to form a transparent part and an opaque part, further arranging them on the opposite surface side, it is possible to slide the movable glass plate on the frame material. Various arrangements can be made within a range that does not deviate from the spirit of the present invention, such as arranging them as a unit and easily attaching them to existing glass windows, or using transparent synthetic resin plate materials instead of glass plates. It can be modified in various ways.

[Advantages of the Invention] According to the present invention, due to the above-described configuration, the cleaning is easy, the structure is simple and the failure is unlikely to occur, and the delicate light-shielding state can be adjusted without power supply. It is possible to provide a partition device that is possible, inexpensive, and easy to use.

Moreover, when the rotary shaft of the operating mechanism is externally rotated, the crank pin slides vertically in the slot or the vertical groove to relatively displace both glass plates, which facilitates relative displacement of both glasses. Therefore, the light blocking state can be finely adjusted. Moreover, since the rotation shaft is provided with the lock mechanism, both the glasses can be reliably stopped at the relative deviation position and the position can be held, and the adjusted light shielding state can be stably maintained.
