Description

  The present invention relates to a joinery provided at an opening of a building and a lock device used for the joinery.

  Openings such as fall windows that open and close are provided in openings such as windows and doors of the building. This type of joinery includes a frame and a shoji attached to the frame so as to be tiltable, and the opening is opened and closed by the tilting of the shoji. The shoji is normally biased toward the open position by a stay damper or the like, while being tilted by a wire via a resin pulley and tilted by winding and unwinding the wire.

  In this joinery, when exposed to high temperatures in the event of a fire, the resin pulley melts early, the restraint by the wire is lost, and the shoji may tilt from the closed position to the open position. As a countermeasure, a lock device that holds the shoji in the closed position in the event of a fire has been proposed (see Patent Document 1). This locking device includes a moving member that is biased by a spring and a fuse member that holds the moving member against the biasing force, and these are fixed to the face of the shoji. In the event of a fire, the fuse member melts, the moving member moves to a position where it can engage with the frame, and even if the pulley melts, the shoji is held in the closed position by these engagements.

Japanese Patent Laid-Open No. 04-266771

  In the structure of Patent Document 1, since the locking device is fixed to the surface where the shoji is found, the temperature rise rate of the fuse member changes depending on the direction in which the fire is expected, and the operability of the locking device Changes significantly.

  This invention is made in view of such a subject, The objective provides the technique which can stabilize operation | movement of a locking device, even if a fire generate | occur | produces in any of the prospective directions of joinery.

  In order to solve the above-described problem, a first aspect of the present invention relates to a joinery. The joinery is surrounded by a frame provided in the opening of the building, a shoji that is attached to the frame so as to be tiltable, and opens and closes the opening by the tilting, and when the shoji is in the closed position. And a locking device that is disposed in the formed hollow portion and holds the shoji in the closed position in the event of a fire.

  Moreover, the 2nd aspect of this invention is related with a locking device. The locking device is a locking device used in a joinery including a frame body provided in an opening of a building and a shoji that is attached to the frame so as to be tiltable and opens and closes the opening by the tilting. And a connecting member to be fixed to one of the frame and the shoji, and attached to the connecting member. A movable member that can be moved to a position, and a holder that holds the movable member in the first position when the shoji is tilted toward the open position, and the movable member is tilted toward the open position. When in the first position, it is impossible to engage with the receiving portion provided on the other of the frame and the shoji, and when in the second position, it is engaged with the receiving portion, and the holder is melted in the event of a fire and the first The moving member can move from the position to the second position by its own weight. And wherein the door.

  According to these aspects, the locking device is disposed in a hollow portion formed by being surrounded by the frame body and the shoji. Therefore, even if a fire occurs in any direction of the fittings, the temperature rise rate of the locking device is less likely to change than when the locking device is fixed to the shoji face, and the operation of the locking device during a fire Can be stabilized.

  Further, in the first aspect described above, the locking device is attached to the attached portion provided on one of the frame and the shoji, and the moving member is movable from the first position to the second position, and the moving member is the first. And the movable member is incapable of engaging with the receiving portion provided on the other of the frame and the shoji when in the first position when the shoji is tilted toward the open position. Yes, it may be engaged with the receiving portion when it is in the second position, the holder is melted in the event of a fire, and the moving member may be movable from the first position to the second position by its own weight. According to this aspect, an urging member such as a spring and a dedicated part such as a shape memory alloy are not required to move the moving member.

  Moreover, in the above-mentioned aspect, the holder may be able to hold the moving member at a distance from the attached portion. According to this aspect, if the distance between the attached portion and the moving member is kept, when the holder starts to melt in the event of a fire, the molten holding tool can flow down from the gap between the moving member and the attached portion. Therefore, it becomes difficult for the holder to remain in the place where the room temperature is located, and the holding of the moving member by the holder is released early.

  Moreover, in the above-mentioned aspect, when the moving member is held at the first position by the holder, the moving member is movable to the opposite side to the second position, and the locking device is moved to the opposite side to the second position. You may further have a fastener which controls a movement of a member. According to this aspect, when the moving member is held by the holder, rattling of the moving member can be suppressed by the fastener.

  According to the present invention, it is possible to stabilize the operation of the locking device regardless of which fire is expected in the fitting direction.

  6A shows a rear view of the locking device 100 corresponding to the arrow C in FIG. 3, and FIG. 6B shows a front sectional view of the locking device 100 corresponding to the cross section taken along the line DD of FIG. Fig.7 (a) shows the EE sectional view taken on the line of Fig.6 (a), FIG.7 (b) shows the FF sectional view taken on the line of Fig.6 (a).

  As shown in FIGS. 4 and 7A, the moving member 120 has a long hole 123 (two in the drawing) penetrating in the thickness direction in the main body 121. In the present embodiment, the long hole 123 is formed so as to extend along the vertical direction. A fastener hole 115 is formed at a position corresponding to the long hole 123 in the attached portion 113 of the connection member 110.

  The fastener 130 illustrates a rivet. The fastener 130 includes a shaft portion 131 that is inserted into the elongated hole 123 of the moving member 120 and the fastener hole 115 of the attached portion 113. The shaft portion 131 of the fastener 130 includes a small diameter portion 131a provided on the distal end side thereof, and a large diameter portion 131b provided on the proximal end side from the small diameter portion 131a. The small-diameter portion 131 a is formed to have a diameter slightly smaller than the fastener hole 115 of the attached portion 113, and is inserted through the fastener hole 115. The large-diameter portion 131 b has a larger diameter than the small-diameter portion 131 a and is formed to have a slightly larger diameter than the fastener hole 115 of the attached portion 113, and is inserted into the long hole 123.

  The fastener 130 includes a head portion 133 provided on the proximal end side of the shaft portion 131 and a retaining portion 135 provided on the distal end side thereof.

Between the head 133 of the fastener 130 and the retaining portion 135, the main body 121 and the attached portion 113 of the moving member 120 are sandwiched. The moving member 120 is connected to the attached portion 113 by the fastener 130.

  Since the shaft portion 131 of the fastener 130 is inserted into the long hole 123 and the fastener hole 115, the moving member 120 moves while the shaft portion 131 of the fastener 130 engages with the long hole 123. Thus, the moving member 120 is guided along the long hole 123. The position and size of the long hole 123 are adjusted so that the moving member 120 can be guided from the retracted position P1 to the engaging position P2.

  FIG. 8 is a cross-sectional view taken along line GG in FIG. The holder 140 includes a base 141, an engagement protrusion 143, and a spacing piece 145. The base 141 is formed in a flat plate shape and is disposed on the side of the main body 121 of the moving member 120. The engagement protrusions 143 are provided so as to protrude from the side surface of the base 141, and two engagement protrusions 143 are provided in the illustrated example. The engagement protrusion 143 includes a shaft portion 143a that extends outward from the side surface of the base portion 141, and a retaining portion 143b that protrudes laterally from the distal end side of the shaft portion 143a. The engaging protrusion 143 is formed in a bowl shape by the shaft portion 143a and the retaining portion 143b. The retaining portion 143b is formed with a guide surface 143c that is inclined so as to approach the base portion 141 toward the distal end side. The interval holding piece 145 is provided so as to protrude from the side surface of the base portion 141.

  The moving member 120 is formed with a first holder hole 125 at a position corresponding to the engagement protrusion 143, and the attached portion 113 of the connection member 110 has a second holder at a position corresponding to the engagement protrusion 143. A working hole 117 is formed. Further, an insertion hole 127 is formed in the moving member 120 at a position corresponding to the interval holding piece 145. As shown in FIG. 6B, the first holder hole 125 includes a first input / output portion 125a through which the engagement protrusion 143 can be inserted and removed, and an upper notch portion 125b formed above the first input / output portion 125a. including. As shown in FIG. 6A, the second holder hole 117 includes a second entrance / exit portion 117a through which the engagement protrusion 143 can be taken in and out, and a lower notch portion formed below the second entrance / exit portion 117a. 117b is included. The insertion hole 127 is formed so as to extend in the direction in which the long hole 123 extends.

  As shown in FIGS. 7B and 8, the holding tool 140 is engaged with the upper protrusion 125 b of the first holding hole 125 and the lower notch 117 b of the second holding hole 117. The shaft portion 143a is inserted. The retaining member 143b of the holder 140 is provided outside the attached portion 113 of the connection member 110, and the moving member 120 and the attached portion 113 are sandwiched between the base portion 141 and the retaining portion 143b. The shaft portion 143a of the holder 140 is engaged with the upper notch 125b of the first holder hole 125 from the lower side and is engaged with the lower notch 117b of the second holder hole 117 from the upper side. The When the moving member 120 is supported by the shaft portion 143a of the holder 140, the downward movement of the moving member 120 is restricted, and the moving member 120 is held at the retracted position P1. At this time, the moving member 120 is attached to the attached portion 113 by bearing support by the holder 140 without being screwed.

  When there is no fastener 130, the moving member 120 can move upward when held by the holder 140 at the retracted position P1. Here, in this embodiment, when the moving member 120 tries to move upward, as shown in FIG. 7A, the shaft portion 131 of the fastener 130 is engaged with the elongated hole 123 from above. That is, the movement of the moving member 120 in the direction (lower side) from the retracted position P1 to the engaging position P2 is restricted by the holder 140, and the moving member toward the opposite side (upper side) of the direction by the fastener 130. The movement of 120 is restricted.

  The interval holding piece 145 of the holder 140 is inserted through the insertion hole 127 as shown in FIG. The interval holding piece 145 comes into contact with the attached portion 113 of the connection member 110 at the tip end portion. Further, as shown in FIG. 7A, the stepped surface 131 c between the small diameter portion 131 a and the large diameter portion 131 b of the fastener 130 contacts the attached portion 113 of the connection member 110. The interval holding piece 145 of the holder 140 and the stepped surface 131 c of the fastener 130 come into contact with the attached portion 113, and the distance between the base portion 141 of the holder 140 and the head 133 of the attachment portion 130 and the attached portion 113. S1 is held. The main body 121 of the moving member 120 is formed to have a thickness smaller than the interval S1, and can be held at the retracted position P1 with a gap from the attached portion 113 by the holder 140. This interval may be provided by adjusting the distance between the operator and the operator after the locking device 100 is disposed in the hollow portion 29 between the frame 20 and the housing 40.

  The holder 140 is made of a resin material or the like as a material. The melting point of the material of the holder 140 is adjusted so as to melt at a predetermined temperature. This melting point is adjusted to a temperature at which at least the shaft portion 143a of the holder 140 is melted prior to the winding member such as the moving member 120, the connecting member 110, and the frame side pulley 51 in the event of a fire.

  The effect of the above joinery 10 is demonstrated. When the frame 20 and the shoji 30 are exposed to a high temperature during a fire, the winding body such as the frame-side pulley 51 around which the cord 55 is wound melts, and the restraining force of the shoji 30 by the cord 55 is increased. The shoji 30 may be lost and tilted to the open position.

  Here, according to the joinery 10 according to the present embodiment, at least the shaft portion 143a of the holder 140 is melted at an early stage in the event of a fire, and the restraint by the holder 140 of the moving member 120 at the retracted position P1 is released. Thereby, the moving member 120 moves from the retracted position P1 (see FIG. 3) to the engaging position P2 (see FIG. 5) by its own weight. Note that the holder 140 is heated by heat transfer from the connection member 110 and the moving member 120 with which the holder 140 contacts, and heat transfer from the air in the surrounding hollow portion 29. Further, the moving member 120 moves while the shaft portion 131 of the fastener 130 is engaged with the long hole 123, is guided along the long hole 123, and moves from the retracted position P1 to the engaging position P2.

  When the moving member 120 moves to the engaging position P2, when the shoji 30 tilts to the open position due to loss of the restraining force of the shoji 30 by the cord 55, the moving member 120 receives the receiving portion of the engaged member 70. 73 is engaged and the shoji 30 is held in the closed position in the event of a fire. Therefore, even if the shoji 30 is tilted to the open position in the event of a fire, it is possible to suppress the formation of a gap between the frame 20 and the shoji 30 and prevent the flame from entering from the gap.

  According to the joinery 10 according to the present embodiment, the locking device 100 is disposed in the hollow portion 29 between the frame body 20 and the shoji 30. Therefore, even if a fire occurs on either side (indoor side, outdoor side) of the prospective direction A of the joinery 10, the temperature rise rate of the lock device 100 is higher than when the lock device 100 is fixed to the finding surface of the shoji 30. It becomes difficult to change greatly, and the operation of the locking device 100 during a fire can be stabilized. In addition, since the locking device 100 is disposed in the hollow portion 29, the locking device 100 is not exposed on the finding surface of the shoji 30 and has a clean appearance and good design.

  Further, since the moving member 120 moves from the retracted position P1 to the engaging position P2 by its own weight, an urging member such as a spring and a dedicated part such as a shape memory alloy are not required to move the moving member 120. Therefore, an increase in the parts cost of the lock device 100 can be suppressed, and the number of parts of the lock device 100 can be reduced to simplify the structure. Also, the biasing member such as a spring usually has a characteristic that the spring index increases and the biasing force decreases as the temperature increases. Therefore, if an urging member such as a spring is used to move the moving member 120, the moving member 120 may not be stably moved during a fire. On the other hand, in the joinery 10 according to the present embodiment, since the moving member 120 is urged by its own weight, the urging force does not decrease even during a fire, the moving member 120 can move stably during a fire, and the operation is stable during a fire. You can get sex.

  Further, the moving member 120 can be held at the retracted position P <b> 1 at a distance from the attached portion 113 of the connecting member 110. Therefore, if the gap between the moving member 120 and the attached portion 113 is kept, when the holder 140 starts to melt in the event of a fire, the molten holding tool 140 flows from the gap between the moving member 120 and the attached portion 113. I can drop it. Therefore, the holder 140 is unlikely to remain in the arrangement place at the normal temperature, and the holding of the moving member 120 by the holder 140 is released early. For this reason, more stable operability can be obtained in a fire.

  Further, the fastener 130 restricts the movement of the moving member 120 toward the side opposite to the direction from the retracted position P1 to the engaging position P2. Therefore, even if the moving member 120 tries to move upward due to external factors such as vibration, the movement is restricted by the fastener 130. For this reason, rattling of the moving member 120 due to an external factor can be suppressed, and the engagement protrusion 143 of the holder 140 can be prevented from coming out from the second holder hole 117 of the connection member 110.

  Further, the attached portion 113 is provided on the connection member 110 that is separate from the frame body 20. Therefore, the connection member 110 functions as a reinforcing member for the frame body 20 and the strength of the frame body 20 is improved. Further, the receiving portion 73 is provided on the engaged member 70 that is separate from the shoji 30. Therefore, the engaged member 70 functions as a reinforcing member for the shoji 30 and the strength of the shoji 30 is improved.

  In addition, the moving member 120 is attached to the attached portion 113 by the fastener 130 and the holder 140 inserted through the moving member 120 and the attached portion 113, and screw fastening is not necessary for the attachment. If the moving member 120 and the attached portion 113 are attached by screw fastening, the screw loosens with time due to the depression of the seating surface, and depending on the attachment method, the moving member 120 is engaged from the retracted position P1 except during a fire. There is a risk of moving to P2. In this respect, according to the locking device 100 according to the present embodiment, such a malfunction other than during a fire does not occur, and stable operability can be obtained over a long period of time. In particular, the depression of the screw seating surface is likely to occur when one of the two members to be screwed is made of a resin material, and even when a resin material is used as the holder 140, it is possible to effectively prevent malfunctions other than during a fire. It can be suppressed.

  Further, when the shaft portion 131 of the fastener 130 as a rivet is inserted into the elongated hole 123 and the fastener hole 115, the step surface 131c contacts the moving member 120. Therefore, when the moving member 120 and the attached portion 113 are connected by the fastener 130, the moving member 120 and the attached portion 113 are fixed between the head portion 133 and the retaining portion 135 of the fastener 130. Disappear. For this reason, it is possible to avoid a situation in which the moving member 120 is sandwiched between the attachment portions 113 by the fastener 130 and cannot move from the retracted position P1 to the engaging position P2. The fastener 130 is inserted into the elongated hole 123 of the moving member 120 from the fastener hole 115 of the attached portion 113, and the step surface 131 c of the shaft portion 131 contacts the moving member 120. You may make it do. Even in this case, the same effect can be obtained.

  Moreover, the locking device 100 can be realized by combining general-purpose materials for the moving member 120, the fastener 130, and the holding tool 140, and can effectively suppress an increase in component costs of the locking device 100.

  In the event of a fire, the attached members 113 of the moving member 120 and the connecting member 110 are more likely to be heated as their thickness is reduced, and the holder 140 that is in contact with them is more likely to be heated by heat transfer. Therefore, according to the locking device 100 according to the present embodiment, in addition to the melting point of the holder 140, the holder 140 can be melted early in the event of a fire by adjusting the thickness of the moving member 120 and the attached portion 113.
