Description

The present invention relates to an opening/closing control device and a fitting.

Some fittings include an opening/closing control device between a frame and a shoji screen. The opening/closing control device switches between a state in which the shoji screen can be fully opened with respect to the frame and a state in which the opening degree of the shoji screen is limited, and includes an arm member and a receiving member. The arm member is a long member provided with an engaging member at the distal end, and is rotatably attached to either one of the frame and the shoji, for example, the shoji, via the base end. The receiving member has a guide groove that slidably accommodates the engaging member of the arm member, and is attached to the other of the frame and the shoji, for example, the frame. The receiving member is provided with a notch at the lower end of the guide groove, through which the engaging member can pass. The notch can be opened and closed by moving a lock member provided on the receiving member.

In this type of opening/closing control device, when the sliding door is moved in the opening direction while the engaging member is housed in the guide groove of the receiving member and the notch is closed by the lock member, the engaging member moves as the sliding door moves. Move upward along the guide groove. Then, when the engagement member reaches the upper end of the guide groove, the movement of the shoji screen is blocked, and the shoji screen can be maintained in a half-open state, for example. On the other hand, when the lock member is moved to open the notch, the engaging member deviates from the guide groove when the shoji is moved in the opening direction. Therefore, the shoji that has moved in the opening direction can be opened to the fully open position because it is not restricted in any way (for example, see Patent Document 1).

By the way, in order to change the position of the lock member, it is necessary to perform it with the shoji closed. However, when the shoji screen is closed, it is difficult to operate the lock member provided between the frame and the shoji screen. For this reason, conventionally, the operation part connected to the lock member is led out to the outside, and the position of the lock member is changed via the operation part.

Here, a tight material is provided between the frame body and the shoji so that water such as rainwater and the outside air do not enter the room when the shoji is closed. Therefore, the operating portion of the lock member needs to pass through the tight material and be led out to the outside. That is, a part of the above-mentioned tight material is interposed between the frame body and the shoji through the operation portion. As a result, there is a possibility that water or outside air may enter due to the step generated by the operation unit. Further, since the operating portion is operated while being pressed against the tight material, the tight material may be damaged.

In view of the above situation, the present invention provides an opening/closing control device and fittings capable of changing the opening of a shoji without inviting water or outside air through the gap between the frame and the shoji. With the goal.

A guide groove for slidably accommodating the guide member is formed, and the guide groove has a leading end at which the engaging member can be deviated, and the arm member is rotatable via a support member. And the engaging member is arranged so as to be located at the lower end of the guide groove when the shoji is closed, while the engaging member is arranged when the shoji moves in the opening direction. Is rotated so as to gradually move to the upper end of the guide groove, and the arm member is attached to the receiving member by contacting the engaging member when the shoji moves in the opening direction. While limiting the opening of the shoji through the arm member, when the arm member is moved in the releasing direction, the contact state with the engaging member is released, and the engaging member causes the guide end of the guide groove to move. An abutting portion that allows passage is provided, and when the support member rotates so that the tip end portion of the arm member moves upward, the tip end portion of the arm member is positioned inside the shoji screen. It is characterized in that it is provided so as to be inclined .

According to this invention, the opening of the shoji is limited by the contact of the engaging member with the abutting portion of the receiving member when the shoji moves in the opening direction. When the engaged state is released, the engaging member can pass through the leading end of the guide groove to change the opening of the shoji. Therefore, it is not necessary to operate with the shoji closed, and the operation part that passes through the tight material provided between the frame and the shoji is also unnecessary, so the tight material between the frame and shoji is damaged. The situation in which water or outside air enters can be reliably prevented.

Further, in the opening/closing control device according to the present invention, a first guide portion and a second guide portion having different extending directions are provided at an upper end portion of the guide groove, and the first guide portion is in contact with the first guide portion. The feature is that it functions as a section.

According to this invention, the first guide portion and the second guide portion having different extending directions are provided in the middle of the guide groove, and the first guide portion functions as the contact portion. Since it is not necessary to separately prepare a member to be in contact with, there is no increase in cost due to an increase in the number of parts or complication of assembling work.

The locking protrusion 122b protrudes so as to be close to the receiving member 121, and is dimensioned so as to prevent the engagement pin 113 of the arm member 111 from passing when it is disposed in the guide groove 121d. is there. The lock member 122 described above can be operated from the front surface side of the receiving member 121 by inserting a tool into the operating recess 122c through the window hole 121p provided in the receiving member 121. In the illustrated example, the lock member 122 is formed with a vertically long concave portion 122c, and the window portion 121p having a narrow width is formed in the base plate portion 121a of the receiving member 121 so as to be substantially arcuate about the shaft member 123. ing. Although not shown in the drawing, the wave washer is provided between the lock member 122 and the receiving member 121 so as to maintain the state in which the lock member 122 and the receiving member 121 are placed in the non-engagement position and the engagement position, respectively, unless a tool is operated. Is intervened.

In the guide unit 120 having the above-described configuration, the mounting piece 121b is vertically arranged so that the guide groove 121d extends along the length of the left vertical frame 13 and when the shoji 20 is closed, as shown in FIG. Further, the engaging pin 113 of the arm member 111 that hangs vertically downward is attached to the prospective surface 13a of the left vertical frame 13 with its position adjusted so as to be arranged at the end 121d1 below the guide groove 121d.

In the fitting including the opening/closing control device 100, as shown in FIG. 7, when the shoji 20 is opened from the closed state with the lock member 122 arranged at the non-engaging position, as shown in FIGS. 8 and 9. In addition, the engagement pin 113 gradually moves upward along the edge of the guide groove 121d while the arm member 111 rotates appropriately. The engaging pin 113 that has moved upward along the guide groove 121d eventually reaches the first guide portion 121g. Here, the first guide portion 121g extends so as to guide the engagement pin 113 toward the closing direction of the shoji 20 and has a width smaller than the head portion 113b of the engagement pin 113. It is composed. Therefore, while the shoji screen 20 is being moved in the opening direction, the engagement pin 113 that has reached the first guide portion 121g is no longer moved upward, and is kept in contact with the contact edge portion 121j. To be done. That is, the shoji 20 with respect to the frame 10 is in a state in which the opening is limited (hereinafter, referred to as a half-open state for convenience). In this half-opened state, the upward movement of the engagement pin 113 is only restricted, and if the shoji 20 is moved in the closing direction as it is, the engagement pin 113 is gradually guided downward and the shoji screen is closed. It is possible to move 20 to the fully closed state.

When the hand is inserted through the gap between the frame body 10 and the shoji 20 in the half-opened state described above, and the distal end portion of the arm member 111 is rotated about the support pin 114 as shown in FIG. The engagement pin 113 reaches the lower end portion of the second guide portion 121h. At this time, in the opening/closing control device 100 of the present embodiment, the sliding contact convex portion 121n is provided on the contact edge portion 121j of the first guide portion 121g. For this reason, the engagement pin 113 moves so as to get over the sliding contact convex portion 121n while moving from the first guide portion 121g to the second guide portion 121h, and the arm when moving over the sliding contact convex portion 121n. A process of applying a force to slightly close the shoji 20 via the member 111 is performed. Therefore, the engagement pin 113 that has reached the second guide portion 121h does not go backward to the first guide portion 121g unless an operating force is applied, and even if it is not supported by the hand, the engagement pin 113 does not reach the lower end portion of the second guide portion 121h. stay.

After that, when the shoji 20 is moved in the opening direction from the above-described state, as shown in FIG. 11, the engagement pin 113 is guided to the outside by the second guide portion 121h, and eventually comes into contact with the lead-out inclined piece 121m. The engaging pin 113 abutting on the lead-out inclined piece 121m is guided to the front surface side of the substrate portion 121a by the tilting action of the lead-out inclined piece 121m, and the arm member 111 resists against the spring force of the torsion coil spring 115 as appropriate. By inclining, it is possible to deviate from the guide end 121k of the guide groove 121d and move the shoji 20 to the fully open position.

At this time, in the opening/closing control device 100 of the present embodiment, the support plate portion 112a of the base member 112 is configured to incline when attached to the prospective surface 24a of the left vertical frame 24, and the tip of the arm member 111 is configured. When the part is rotated so as to move upward, its tip end is located inside the shoji 20. That is, as shown by the alternate long and two short dashes line in FIG. 12, the tip end of the arm member 111 that has been rotated upward goes beyond the imaginary plane S including the prospective surface 24a, and the glass 21 is placed inside the shoji 20. The support pin 114 is provided so as to be inclined so as to be located on the side. Therefore, when the arm member 111 rotates, a gap is secured between the left end of the left vertical frame 13 and the engaging pin 113 or the tip end of the arm member 111 that has deviated from the guide groove 121d of the receiving member 121, and they contact each other. There is no chance of contact.

Here, in the opening/closing control device 100 in which the support pin 114 of the arm member 111 is inclined with respect to the prospective surface 24a of the left vertical frame 24 as described above, as shown in FIG. When the engagement pin 113 of is engaged with the end portion 121d1 below the guide groove 121d, as shown in FIG. 13, the portion of the head 113b of the engagement pin 113 that is on the indoor side is the left vertical frame 13. It is inclined so as to be separated from the surface 13a. Therefore, from this state, as shown in FIG. 12, when the distal end portion of the arm member 111 moves so as to be positioned inside the shoji 20, that is, when it moves away from the substrate portion 121a of the receiving member 121, The amount of engagement between the head 113b of the engagement pin 113 and the receiving member 121 is reduced. However, in the opening/closing control device 100 described above, the bulging portion 121f is provided at the lower edge portion in FIG. 13 at a portion extending from the lower end portion 121d1 of the guide groove 121d to the lower end portion of the passage portion 121d2. is there. Therefore, the head portion 113b of the inclined engaging pin 113 is guided to the passage portion 121d2 by the bulging portion 121f and does not deviate from the guide groove 121d.

Further, even if the shoji 20 moves in the closing direction due to the influence of wind or the like while operating the arm member 111, the engagement pin 113 abuts on the edge portion of the guide groove 121d, so that the arm member 111 is framed. It will be interposed between 10 and the shoji 20 in a stretched manner, and will prevent further movement in the closing direction. Therefore, a problem such as a finger operating the arm member 111 being caught does not occur.

After the engagement pin 113 has deviated from the guide groove 121d of the receiving member 121, the arm member 111 is hung below the support pin 114 due to the spring force of the torsion coil spring 115 and its own weight. At this time, the rotation restricting piece 112d of the base member 112 is in contact with the arm member 111. Therefore, when the shoji 20 is moved from the open state beyond the half open state in the closing direction, the engagement pin 113 of the arm member 111 eventually contacts the introduction inclined piece 121e provided on the receiving member 121 as shown in FIG. Contact. The engaging pin 113 abutting on the introduction inclined piece 121e is guided to the front surface side of the substrate portion 121a by the inclination action of the introduction inclined piece 121e, and the arm member 111 appropriately resists the spring force of the torsion coil spring 115. Incline. As a result, when the shoji 20 is further moved in the closing direction, the engagement pin 113 returns to the state of being introduced into the end portion 121d1 below the guide groove 121d.

On the other hand, when the shoji 20 is moved from the closed state to the open direction with the lock member 122 arranged at the engagement position, the engagement pin 113 abuts on the locking projection 122b, and thereafter, the upward movement is performed. Movement is blocked. As described above, the lock member 122 cannot be operated without inserting a tool into the recess 122c through the window hole 121p. Therefore, even if the child is mischievous, the lock member 122 does not easily return to the non-engagement position, and it is possible to maintain the state in which the shoji 20 is not inadvertently fully opened.

As described above, according to the fitting including the opening/closing control device 100, when the shoji 20 moves in the opening direction, the engagement pin 113 abuts on the abutting edge 121j of the receiving member 121 to open the shoji 20. Is limited to a half-open state, and when the engagement state between the engagement pin 113 and the contact edge 121j is released from the half-open state, the engagement pin 113 passes through the lead-out end 121k of the guide groove 121d to fully open the shoji 20. Can be moved to a position. Therefore, it is not necessary to perform the operation of changing the opening degree of the shoji 20 with the shoji 20 being closed, and the operation of passing through the tight material 200 (see FIG. 12) provided between the frame body 10 and the shoji 20. Parts are also unnecessary. Therefore, the tight material 200 between the frame 10 and the shoji 20 is not damaged, and it is possible to reliably prevent the situation where water or the outside air enters.

Moreover, the first guide portion 121g and the second guide portion 121h having different extending directions are provided above the guide groove 121d, and the edge portion located above the first guide portion 121g functions as the contact edge portion 121j. Therefore, it is not necessary to separately prepare a member to be brought into contact with the engagement pin 113, and there is no increase in cost and complexity of assembly work due to an increase in the number of parts.

In the above-described embodiment, the support pin 114 that supports the arm member 111 is tilted with respect to the prospective surface 24a of the left vertical frame 24, and when the arm member 111 rotates, the tip portion is on the inner side of the shoji 20. Although the present invention is not limited to this, the present invention is not limited to this, and it is possible to use other methods so that the tip end portion moves inward of the shoji 20 when the arm member 111 rotates. Is.

For example, as in the modified example 1 shown in FIGS. 15 to 17, the protrusion 112e may be provided at the edge of the base member 112. That is, in the first modification, the protrusion 112e is provided on the edge of the base member 112 so as to contact the base end of the arm member 111 only when the tip end of the arm member 111 moves upward.

Further, as in Modification 2 shown in FIGS. 18 to 20, a protrusion 114c is formed at a portion of the head 114b of the support pin 114 that faces the base end of the arm member 111, and the base end of the arm member 111 is formed. In the above, the recess 111d may be formed in a portion of the support pin 114 that faces the head 114b. That is, in the second modification, as shown in FIG. 18A, when the arm member 111 hangs from the support pin 114, the protrusion 114c of the support pin 114 is housed in the recess 111d of the arm member 111. On the other hand, when the tip of the arm member 111 moves upward, the projection 114c of the support pin 114 is brought into contact with the base end surface of the arm member 111. In both the first modification and the second modification, it is not necessary to incline the support pin 114 with respect to the prospective surface 24a of the left vertical frame 24. In addition, in these modified examples 1 and 2, the same components as those of the embodiment are denoted by the same reference numerals and detailed description thereof is omitted.

Further, in the above-described embodiment, the vertically long concave portion 122c provided in the lock member 122 is operated through the narrow window hole 121p provided in the upper end portion of the receiving member 121, but FIG. As shown in the third modified example, a horizontally long recess 122c' is formed in the lock member 122, and a wide window hole 121p is formed in the base plate portion 121a of the receiving member 121 so as to be substantially arcuate about the shaft member 123. ′ May be formed. In Modification 3, the same components as those in the embodiment are designated by the same reference numerals and detailed description thereof is omitted.

Furthermore, as in Modification 4 shown in FIGS. 22 and 23, it is also possible to configure the operating knob 122d to project from the lower portion of the receiving member 121. That is, in the modified example 4, the vertically long locking member 122 is applied, and the locking protrusion 122b is provided so as to correspond to the upper end portion of the first guide portion 121g. Also in this modified example 4, by operating the operating knob 122d from the non-engagement position shown in FIG. 23(a), as shown in FIG. 23(b), the first guide portion 121g is locked. When the protrusion 122b is arranged and brought to the engagement position, the engagement pin 113 of the arm member 111 abuts on the locking protrusion 122b and is prevented from moving upward, so that the shoji 20 is inadvertently moved to the fully open position. It is possible to prevent the situation that is opened up. In Modification 4, the same configurations as those of the embodiment are denoted by the same reference numerals and detailed description thereof is omitted.

Further, as in the modified example 5 shown in FIGS. 24 and 25, if the locking member 122 is provided with the engaging piece 122e, it is advantageous in terms of crime prevention. That is, in the fifth modification, similarly to the embodiment, the lock member 122 is rotatably arranged above the receiving member 121, and when the lock member 122 is arranged at the engagement position, the lock protrusion 122b is first guided. In addition to being located at the portion 121g, the engaging piece portion 122e is provided so as to extend below the locking protrusion 122b. As shown in (a) and (b) of FIG. 25, the engaging piece 122e is arranged at a position retracted from the guide groove 121d when arranged at the engaging position and the non-engaging position. On the other hand, the engagement piece portion 122e is provided so as to cross the guide groove 121d when the lock member 122 moves between the engagement position and the non-engagement position. When the lock member 122 is rotated toward the non-engagement position in a state where the engagement pin 113 is in contact with the locking protrusion 122b in the guide groove 121d, the engagement piece portion 122e has a shape similar to that of the engagement pin 113. It is configured so as to be able to contact the side surface.

According to this modified example 5, as shown in (b) of FIG. 25, in the state where the shoji 20 is opened until the engagement pin 113 contacts the locking projection 122b, the lock member 122 is set to the non-engagement position. When it is attempted to move toward the end, the engagement piece 122e comes into contact with the side surface of the engagement pin 113. That is, when the shoji 20 is in the half-opened state, the lock member 122 cannot be operated from the engaged position to the non-engaged position. In order to move the lock member 122 arranged in the engagement position in the modified example 5 to the non-engagement position, the opening degree of the shoji 20 is limited to a small value, as shown by the chain double-dashed line in FIG. It is necessary to dispose the engagement pin 113 below the guide groove 121d up to a position where it does not come into contact with the engagement piece 122e. Therefore, it becomes difficult to move the lock member 122 arranged at the engagement position from the outdoor side to the non-engagement position, which is advantageous in terms of crime prevention. In Modification 5, the same configurations as those of the embodiment are denoted by the same reference numerals and detailed description thereof is omitted.
