Description

  The present invention relates to a fixture such as a raising and lowering window attached to a frame of an opening of various buildings such as a house or a building.

  2. Description of the Related Art Conventionally, upper and lower windows are known that store upper and lower sets in a frame attached to an opening of a building, and hold the upper sets and allow the lower sets to move up and down. As an example of such a raising and lowering window, for example, the one described in Patent Document 1 has been proposed. The upper window and the lower window are arranged in a plane in the vertical direction in the frame body in the closed state of the window, and the guide grooves formed on the indoor side of the left and right vertical frames are upward from the lower end It has an inclined groove which is inclined toward the diagonal direction and a linear groove which extends in the vertical direction. Then, the lower shutter operates to open and close along the guide groove.

  As shown in FIG. 12 (a), the conventional raising and lowering window 100 described in Patent Document 1 is provided slidably on the main body portion 102 formed on the upper lid of the lower shoji 101 as a locking mechanism for the lower shoji 101. Lock member 105 lockable to the hook-like lock receiving portion 108 in the recessed groove 103a of the vertical frame 103, and a latch member 106 which can be engaged and disengaged between the piece 103d and the guide groove 103b by elasticity Have to.

The lock member 105 is inserted into and removed from the lock receiving portion 108 in the recessed groove 103a by sliding the operation portion 109, thereby performing locking (locking) and releasing thereof. The distal end portion of the lock member 105 has a two-step shape of a central convex curved portion 105a and an end corner portion 105b having a low height, as shown in FIG. It is locked by advancing to the inside of 103 a and causing the convex curved portion 105 a and the end corner portion 105 b to get over the lock receiving portion 108 to be elastically deformed and to be engaged with the side surface of the lock member 105.
The lock member 105 is formed by bending a steel plate in a substantially U-shaped cross section for reinforcement, and the end face forms a convex curved portion 105a by press processing, so the end corner portion 105b of the plate thickness is formed at the bent portion. Were formed, and there were burrs on the corner.

Further, as shown in FIGS. 13A and 13B, the latch member 106 has a latch core metal 106a held in an advance / retractable manner by a pair of latch receiving portions 107 formed in the main body portion 102 and having a substantially L-shaped cross section. A fine gap t of, for example, about 0.15 mm is formed as a play between the latch receiving portion 107 and the latch core metal 106 a for smooth mounting and operation.
Then, when the shutter member 101 in the closed state is released, the lock member 105 is pulled out from the recessed groove 103 a to release the lock, and the latch member 106 is biased by the spring when the shutter member 101 is turned indoors. On the other hand, it retracts from the recessed groove 103a to release the engagement, and moves to the guide groove 103b to be engaged again. Next, by lifting the lower shoji 101, the lower shoji 101 rises along the guide groove 103b to the upper shoji side and is in an open state.

JP 2012-1897 A

However, in the conventional raising and lowering window 100 as described in Patent Document 1, there is a play of a minute gap t between the latch member 106 and the latch receiving portion 107, so that the latch is performed when opening and closing the lower shoji 101. The member 106 moves between the recessed groove 103a of the vertical frame and the guide groove 103b and disengages, and collides with the vertical frame partitioning the recessed groove 103a and the guide groove 103b to generate a squeegee and noise. There was a drawback that it was offensive and uncomfortable.
In addition, since the latch member 106 has a convex curved portion with a relatively small diameter (for example, a radius of less than 7 mm) on both sides of the central plane, the latch member 106 smoothly moves in order to fall into the concave groove 103a and the guide groove 103b. There was a drawback that an impact sound was generated.

  In addition, the lower shoji 101 inserts the lock member 105 into the recessed groove 103a at the closed position where it is flat with the upper shoji and locks the lock receiving portion 108, but the end corner portion 105b of the locking member 105 is the lock receiving portion When it passes over 108, it rubs with end corner 105b, resistance is large, and there was a fault which requires large power for opening and closing operation.

  In addition, since the collar of the lower shoji piece 101 is repelled by the elasticity of the airtight holding packing provided on the vertical frame 103 at the time of closing, the end corner portion 105b of the lock member 105 is difficult to get over the lock receiving portion 108 also at this point. . Moreover, since the tip of the lock member 105 is formed in a two-step shape, when the lock receiving portion 108 abuts on and engages with the second corner portion 105 b after crossing the central convex curved portion 105 a In some cases, the operator may misunderstand that the lower shutter 101 is locked in the closed position at a position where the click is caused by the step and the lock position is not reached. In this case, there is a drawback that the closing of the lower case 101 is insufficient and air tightness and heat insulation can not be secured.

This invention is made in view of such a subject, Comprising: It is providing the fixture which improved operativity so that opening-and-closing operation could be performed reliably, without generating noise at the time of opening-and-closing of a shojiji. With the goal.

In addition, when the latch portion 62a is engaged with or disengaged from the recessed groove 60 or the guide groove 15, the latch portion 62a has the curved surface portions 62c with large roundness on both sides of the central flat portion 62b. When engaging or disengaging, it can move smoothly and get over, and the collision noise can be reduced.

Then, when the operator lifts the lower slide 4 along the guide groove 15 by lifting the pull tab 30 and the pull tab 37a by hand, the lower slide 4 is supported by the support member 13 fixed to the lower hook 24 and the latch member 57. It rises along the inclined groove 15a and the linear groove 15b of the guide groove 15, and reaches the fully open position held parallel to the upper shoji 3 as shown in FIG.
In addition, the lower visor 4 stops at an arbitrary opening position by the biasing force of the winding spring in the balancer 11 in which the upper end of the wire 12 for pulling up the support member 13 is connected.

Next, in order to close the lower opening 2 in the fully open state, the operator grips the pulling portion 30 or the opening 37a from the position where the lower opening 4 is held parallel to the upper 3 by the linear groove 15b of the guide groove 15. Then, the lower shutter 4 is lowered along the guide groove 15.
Then, the lower shutter 4 reaches the half open state in which the support member 13 reaches the lower end of the inclined groove 15a and is in the inclined state. Then, the latch member 57 is retracted from the guide groove 15 against the biasing force of the coil spring 66 by rotating the lower shoji 4 toward the outdoor side, ie, the upper shoji 3, with the support member 13 as the fulcrum. The latch portion 62a of the latch member 57 is engaged by the biasing force of the coil spring 66 with the concave groove 60 of the vertical frame 8, 9 provided on the outdoor side.

Then, the operating portion 71 is operated to slide to advance the lock member 58 into the recessed groove 60. Then, as shown in FIG. 5 and FIG. 9B, the central convex curved portion 72a at the tip end portion of the lock member 58 presses and deforms the hook-like lock receiving portion 70 in the recessed groove 60 and gets over. Next, the lock receiving portion 70 abuts on the end convexly curved portion 72b of the lock member 58, but since the end convexly curved portion 72b is also formed in a convexly curved shape, a click feeling can not be obtained. Then, in a state where the lower frame 24 and the longitudinal ridges 25 and 26 of the lower shoji 4 press the packings 45 and 46 provided on the lower frame 7 and the longitudinal frames 8 and 9, the end convexly curved portion 72b of the lock member 58 locks The receiving portion 70 is elastically deformed and passed over to be brought into contact with the side surface 58 d to be in an airtight lock (locking) state.
Thus, the lower visor 4 reaches the closed position overlapping with the upper visor 3 shown in FIG.

As described above, according to the raising and lowering window 1 according to the present embodiment, the latch member 57 is pressed against the latch receiving portion 64 by the projection 67 and slidably supported, and there is no play. The latch member 57 does not make a rattling noise when rotating between the positions. In addition, when the latch portion 62a moves between the recessed groove 60 and the guide groove 15, since the latch portion 62a has the curved surface portion 62c with a large radius on both sides of the central flat portion 62b, the recessed groove 60 and the guide groove It can move smoothly and get over when engaging 15 and reduce the collision noise. Therefore, the operability of the lower barrier 4 improves.
In addition, since the lock member 58 has the central convex curved portion 72a and the end convex curved portion 72b of the thick portion, when the lock member 58 elastically deforms and gets over the hook-like lock receiving portion 70, the lower frame 7 and the vertical frame In a state where the packings 45 and 46 provided at 8 and 9 are compressed, they can be smoothly moved to the lock position. Moreover, when the lock member 58 passes over the lock receiving portion 70, a click does not occur between the central convex curved portion 72a and the end convex curved portion 72b. It can be locked in the closed position.

In addition, the raising / lowering window 1 by this invention is not limited to embodiment mentioned above, A suitable change, substitution, etc. are possible in the range which does not deviate from the summary of this invention.
For example, in the embodiment described above, when the lock member 58 passes over the lock receiving portion 70, as shown in FIGS. 9A and 9B, a two-step curved surface consisting of a central convex curved portion 72a and an end convex curved portion 72b. However, the present invention is not limited to such a configuration.
For example, as shown in FIG. 9C, one convex curved portion 74 may be formed. In this case, by pressing with one die, the bottom 58b of the thick portion can also form a substantially arc-shaped convex curved portion 74 integrally with the short piece 58a and the long piece 58c. In this case, since the operator does not feel the click feeling due to the step more surely in the middle of the locking process, the locking operation can be performed more smoothly and surely.

In the embodiment described above, the protrusion 67 is provided on the back surface of the slidable latch member 57 so that the latch member 57 abuts on the latch receiving portion 64 so as to eliminate the play. It is not limited. For example, in place of the protrusions 67 provided on the latch plate 62 of the latch member 57 as described above, the protrusions 67 may be provided on both sides of the lower long groove 56a in the main body portion 56. Further, the projection 67 may be provided on the latch core 61, or the projection 67 may be provided on one of the upper and lower surfaces of the latch receiving portion 64 to make the latch member 57 one or the other of the latch receiving portion 64. The surface may be pressed.
The protrusions 67 may be formed of either metal or resin.

Moreover, although the raising / lowering window 1 as a fixture by this invention used upper shoji 3 in the frame 2 as fixed shoji, and set the lower shoji 4 as movable shoji, the fixed shoji lowers with the frame 2 conversely with this. The movable shoji may be placed on the upper side and the vertical direction may be reversed, or the fixed shoji and the movable shoji may be arranged in the lateral direction.
