Description

  The present invention relates to a joinery including a frame and a shoji.

  In the fittings installed at the opening of the building, the shoji is attached to the frame so as to be openable and closable, and the opening and closing of the shoji is operated by the operation member. A latch device is used to lock the shoji with the frame closed. The latch device includes a latch receiver provided on the frame body, and a latch provided on the casing of the shoji and engaged with the latch receiver. In the latch device, it is necessary to release the engagement between the latch and the latch receiver when opening the shoji. On the other hand, there is conventionally known an inward-turning window in which an operation member and a latch are provided on the upper cover of the shoji and the latch is moved using the operation member (see Patent Document 1).

  However, in the conventional inward window described in Patent Document 1, the latch is operated by the operating member in the upper collar member provided with the latch. Therefore, when the upper collar is in a position where it is difficult to operate, the opening / closing operation of the shoji may not be easily performed. For example, when the upper collar is at a high position on the wall, it is necessary to operate the latch with the operation member with the hand extended upward. In particular, when the height of the operating person is low, or when there are obstacles (tables, furniture, etc.) in front of the inside-turned window, the opening / closing operation of the shoji becomes more difficult.

  When the shoji 20 is opened, the latch 41 moves from the engagement position K1 to the release position K2 and comes off the latch receiver 42. In that state, the shoji 20 moves in the opening direction H, and the shoji 20 opens. After the shoji 20 starts to move, the latch 41 is moved from the release position K2 to the engagement position K1 by the biasing means 43. When closing the shoji 20, the shoji 20 moves in the closing direction T, and the latch 41 at the engagement position K1 comes into contact with the latch receiver 42. At that time, the inclined portion 41 </ b> B of the latch 41 contacts the protruding portion 42 </ b> A of the latch receiver 42.

  The inclined portion 41 </ b> B of the latch 41 is inclined with respect to the closing direction T of the shoji 20 and the urging direction of the latch 41 by the urging means 43. As the shoji 20 is closed, the inclined portion 41B of the latch 41 is pushed by the protruding portion 42A of the latch receiver 42, and the latch 41 moves from the engagement position K1 toward the release position K2. When the shoji 20 is closed, the latch 41 moves to a position where the latch 41 can be engaged with the latch receiver 42 and is disengaged from the protrusion 42A of the latch receiver 42. At the same time, the latch 41 is moved to the engagement position K 1 by the urging force of the urging means 43 and is engaged with the latch receiver 42.

At that time, as the slide member 51 slides, the contact portion 51 </ b> B of the slide member 51 contacts the contact portion 52 </ b> B of the displacement member 52.

  The contact part 52B of the displacement member 52 is pushed in the slide direction (here, upward) of the slide member 51 by the contact part 51B of the slide member 51, and moves in the slide direction. Thereby, the displacement member 52 rotates and displaces, and the latch portion 52A of the displacement member 52 moves in the direction opposite to the sliding direction (here, downward). The displacement member 52 moves the latch 41 from the engagement position K1 to the release position K2 by moving the latch 41 together with the latch portion 52A in the displacement direction.

  When the operation member 2 moves from the second position P2 to the first position P1, the slide member 51 slides downward and moves away from the displacement member 52. At the same time, the latch 41 is moved from the release position K2 to the engagement position K1 by the bias of the biasing means 43. Moreover, the displacement member 52 rotates and displaces, and the contact part 52B of the displacement member 52 moves downward. In a state where the operation member 2 is disposed at the first position P1, the contact portion 51B of the slide member 51 and the contact portion 52B of the displacement member 52 do not contact each other, and a gap 54 is formed between the two contact portions 51B and 52B. The

  When the shoji 20 is opened (see FIGS. 5 and 6), the grip 2B of the operation member 2 is pulled in the opening direction H of the shoji 20, and the grip 2B is moved in the opening direction H. Accordingly, the operation member 2 moves from the first position P1 to the second position P2. In conjunction with the movement of the operation member 2, the interlocking mechanism 50 moves the latch 41 to the release position K2, and the engagement between the latch 41 and the latch receiver 42 is released. As a result, the latch 41 is released from the latch receiver 42 and the lock of the shoji 20 is released. Subsequently, the grip portion 2 </ b> B of the operation member 2 is pulled in the opening direction H of the shoji 20.

  The shoji 20 is pulled in the opening direction H (inside the room) by the operation member 2 and moves in the opening direction H. Subsequently, the shoji 20 moves and opens so as to fall down toward the indoor side. The opening degree of the shoji 20 is regulated by, for example, an opening degree regulating device. The shoji 20 is arranged in an open state with a predetermined opening. After the movement of the shoji 20 starts, the operation member 2 moves from the second position P2 to the first position P1, and the latch 41 moves from the release position K2 to the engagement position K1.

  When closing the shoji 20, the grip 2B of the operation member 2 is pushed in the closing direction T of the shoji 20 (the frame 10 side). The shoji 20 is pushed in the closing direction T by the operation member 2 and moves in the closing direction T. Subsequently, the shoji 20 moves to the frame 10 and closes. At that time, the latch 41 is pushed by the latch receiver 42 and moves toward the release position K2. When the shoji 20 is closed, the latch 41 moves to the engagement position K1 and engages with the latch receiver 42, and the latch 41 locks the shoji 20 in the closed state.

Therefore, the latch 41 can be easily operated by the operation member 2 at a position lower than the first bridging material 31. As described above, the latch 41 is operated in the second saddle member 32 at a position where the operation is easier than the first saddle member 31 provided with the latch 41, and the opening / closing operation of the shoji 20 can be easily performed.

  When opening the shoji 20, the grip 2B of the operation member 2 is moved toward the opening direction H of the shoji 20, and the latch 41 is moved to the release position K2. Therefore, following the disengagement of the latch 41 and the latch receiver 42, the shoji 20 can be smoothly moved in the opening direction H by the operation member 2. In connection with this, the operation | movement when opening the shoji 20 becomes easy, and the shoji 20 can be opened easily and smoothly. Further, by simply closing the shoji 20, the latch 41 can be engaged with the latch receiver 42 and the shoji 20 can be locked.

  The interlocking mechanism 50 interlocks the latch 41 with the operation member 2 by two members, the slide member 51 and the displacement member 52. Therefore, the latch 41 can be reliably interlocked with the operation member 2 while suppressing the structure of the interlocking mechanism 50 from becoming complicated. By housing the slide member 51 and the displacement member 52 in the grooves (the guide groove 32A and the housing groove 31A) of the housing 30, the appearance of the shoji 20 can be improved. The displacement member 52 can be accurately displaced by the guide of the guide member 53, and the movement of the latch 41 can be stabilized.

  Since the displacement member 52 is a rotating member that rotates about the rotating shaft 52C, the latch 41 provided in the latch portion 52A can be accurately moved. Even if the distance between the latch 41 and the slide member 51 is increased, the latch 41 can be reliably moved by the rotational displacement of the displacement member 52. By changing the length of the displacement member 52 (distance between the latch portion 52A and the contact portion 52B), it is possible to easily cope with the change in the position of the latch 41, and to latch the first rod 31 of various lengths. 41 can be provided.

  The center of gravity of the displacement member 52 may coincide with the axis of the rotation shaft 52C or may deviate from the axis of the rotation shaft 52C. On the other hand, the center of gravity of the displacement member 52 may be located closer to the latch portion 52A than the rotation shaft 52C, or may be located closer to the contact portion 52B than the rotation shaft 52C. When the center of gravity of the displacement member 52 is positioned closer to the contact portion 52B than the rotation shaft 52C, the balance between the latch 41 and the displacement member 52 is adjusted, and the latch 41 is easily moved from the release position K2 to the engagement position K1. be able to. Further, when the contact portion 52B of the displacement member 52 moves downward due to gravity, the latch 41 can be urged toward the engagement position K1 by the gravity that moves the contact portion 52B. Thus, by utilizing the center of gravity of the displacement member 52, the latch 41 can be easily moved (returned) to the engagement position K1. The biasing force of the latch 41 is adjusted by positioning the center of gravity of the displacement member 52 between the rotation shaft 52C and the contact portion 52B.

  By using the biasing means 43, the latch 41 can be reliably moved (returned) to the engagement position K1. Further, the latch 41 can be reliably maintained in the state of being engaged with the latch receiver 42 by the bias of the biasing means 43. When the latch 41 is moved, the movement of the latch 41 can be assisted by using the center of gravity of the displacement member 52. On the other hand, at least one of the centroids of the urging means 43 and the displacement member 52 may be used for the movement of the latch 41 to the engagement position K1. That is, the center of gravity of the biasing means 43 and the displacement member 52 may be used together, or only the biasing means 43 or only the center of gravity of the displacement member 52 may be used.

  The latch 41 may be formed integrally with the latch portion 52A of the displacement member 52. The latch 41 may be a member different from the displacement member 52. In this case, the latch 41 is attached to the latch portion 52 </ b> A of the displacement member 52 and is held by the displacement member 52.

  Here, the latch 41 is provided on the upper saddle member, and the operation member 2 is provided on the vertical saddle member. On the other hand, the latch 41 may be provided on the vertical hook material or the lower hook material corresponding to how the shoji 20 is opened. In this case, the first brazing material 31 is a vertical brazing material or a lower brazing material. The operation member 2 is provided on a second saddle member 32 (an upper saddle member, a lower saddle member, or a vertical saddle member) different from the first saddle member 31. Based on the installation conditions of the joinery 1 (for example, the positions of the first frame 31 and the other frames 32 to 34), the frame at a position that is easier to operate than the first frame 31 is used as the second frame 32. Is set. The first brazing material 31 and the second brazing material 32 may be brazing materials whose ends are connected to each other, or may be brazing materials facing each other.

  As described above, the example in which the present invention is applied to the inversion window has been described. However, the present invention may be applied to the inversion window. In addition, the present invention can be applied to various fittings (windows, doors, etc.) provided with the frame 10 and the shoji 20.
