Description

  The present invention relates to an opening device, and more particularly, to an opening device including an assist mechanism and a door lock that reduce a force at the start of opening a shoji.

  In the sliding sash, which is an opening device, a large frictional resistance is generated between the airtight material of the frame and the shoji due to the wind pressure or the atmospheric pressure difference between the inside and outside at the beginning of opening the shoji, and a very large force is used to open the shoji. Although it is necessary, if the shoji opens a little and the shoji moves away from the vertical seal, the shoji can be moved easily. In order to make the operation of opening the shoji easier, an assist handle using the lever principle has been proposed (see, for example, Japanese Patent Application Laid-Open No. 2003-13634). This assist handle has a lever member that is pivotally supported on the door rod (door portion) of the shoji so that it can pivot in a vertical direction within a plane substantially parallel to the surface of the shoji. By turning and holding the lever, the shoji can be opened by the reaction of pushing the vertical frame at the other end of the lever member.

  On the other hand, recently, in order to improve crime prevention, a lock has been required not only on the calling side but also on the door end side for the purpose of increasing the number of locking portions of the sash (Japanese Patent Laid-Open No. 2004-52218). See the public relations).

Mounting piece portions 22a for stopping are formed on the top and bottom.

  The position of the indoor portion of the operation portion 18 or the member that houses the operation portion 18 (the handle portion 25 in the illustrated example) does not interfere with the outdoor portion of the inner shuffle 3 when the operation portion 18 is attached to the outer obstacle 4. Is provided. Preferably, the operation portion 18 does not protrude from the indoor surface of the door toe 6d or protrudes only to the extent that it does not interfere with the outdoor portion of the inner shoji 3 (as large as the conventional assist handle). Not protruding). Here, the outdoor portion of the inner shoji 3 refers to, for example, the outdoor portion of the summon bowl 5c, the outdoor surface of the smoke return, the outdoor portion of the crescent pedestal and its mounting portion. A handle part (also referred to as an indoor side handle part) 25 is provided on the indoor surface of the door rod 6d. When the operation part 18 is in the closed operation position (the door lock is locked), the handle part 25 is provided. And is slidable so as to be opened when it is in the opening operation position (the door lock is unlocked). Mounting holes (not shown) for attaching the indoor side handle part 25 and the outdoor side handle part 26 are provided in the indoor surface and the outdoor surface of the door rod 6d.

  As shown in FIG. 10, the pulling portion 25 has a vertically long box shape with openings (25a, 25b) at the indoor front portion and the lower portion, and a flange 25c is formed on the indoor peripheral edge. The operation portion 18 has a vertically long plate shape, and is slidably inserted into the handle portion 25 from the lower opening 25b. A finger hooking portion 18a is formed on the interior surface of the upper end portion of the operation portion 18 as a concave portion for inserting an index finger to raise and lower the operation portion 18. In order to prevent the operation unit 18 from falling off from the handle part 25, a slot hole 18b elongated in the vertical direction is formed in one side part of the operation part 18, and the slot hole 18b is formed in one side part of the handle part 25. A pin 27 is slidably engaged with the pin 27. In addition, in order to position and lock the operation unit 18 at the upper position that is the locking position and the lower position that is the unlocking position, a locking piece 25d having a spring property is provided on the inner surface of the other side portion of the pulling portion 25. Engagement recesses 28a and 28b are formed on the other side of the operation portion 18 and engage with the locking piece 25d (see FIG. 11).

  The upper end portion of the slider 23 is connected to the back surface of the lower end portion of the operation portion 18 with a fixing tool such as a screw 29. An engagement groove 25e that engages with the lower edge of the mounting hole on the indoor surface of the door rod 6d is preferably formed at the lower end of the indoor side pulling portion 25. The indoor side pulling portion 25 and the outdoor side pulling portion 26 are arranged back to back as shown in FIGS. 2 to 4B, and are connected to each other by screws 30 screwed from the indoor side. By screwing the screw 30 from the indoor side, the outdoor handle 26 is removed from the outside and the door lock 19 is prevented from being unlocked illegally, thereby improving crime prevention.

  As shown in FIG. 8, the kick-out member 16 is made of a substantially triangular (preferably substantially right-angled triangle) plate material, and is provided with a shaft hole 16a through which the support shaft 23 passes at one end, and is kicked out to one side of the other end. An operating shaft portion 16c with a flange 16b for rotating the member 16 is projected, and the other side surface of the other end is twisted as a biasing means for biasing the kicking member 16 in the kicking direction. A locking portion 16 d that locks one end of the spring 31 is provided. In the kick-out member 16, a pressing portion 16e consisting of a substantially right-angled corner portion (with curved surface processing) is rotated from the shaft hole 16a as a fulcrum and protrudes from the end surface 24 of the door-end rod 6d. Thus, the vertical frame 2c is kicked (pushed). The torsion spring 31 is supported by the support shaft 21 and the other end is locked in the case portion 22.

  As shown in FIG. 9, the sickle portion 19 a of the door lock 19 is provided with a shaft hole 19 b through which the support shaft 20 is passed, and an operation shaft portion 19 c for rotating the sickle portion 19 a on one side of the other end. Is protruding. As shown in FIGS. 2, 12 to 13, the sickle portion 19 a of the door lock 19 is inserted into the latch hole 32 a and is latched (locked) on the inner surface of the vertical frame 2 c. A receiving member 32 having upper and lower portions 32b and a receiving portion 32c against which the kick-out member 16 is pressed is attached by screwing. The receiving member 32 is not necessarily required, and the sickle portion of the door-end lock is inserted and locked in the locking hole formed in the vertical frame 2c, or the kicking member directly kicks the vertical frame. It may be.

  As shown in FIGS. 13 to 14, the slider 23 can unlock the sickle portion 19 a of the door lock 19 by sliding the slider 23 from above to below or sliding from below to above. A guide groove 33 is provided for engaging and guiding the operation shaft portion 19c of the sickle portion 19a for locking. The guide groove 33 includes a vertical intermediate portion 33a that holds the sickle portion 19a at an intermediate position inclined 45 degrees obliquely upward, and an unlocked position by rotating the sickle portion 19a 45 degrees clockwise from the intermediate position. And the lower inclined portion 33c that turns the sickle portion 19a counterclockwise by 45 degrees from the intermediate position to the locked position. It is important that the sickle portion 19a is detached from the receiving portion 32b before the kicking member 16 kicks the vertical frame 2c, and the sickle portion 19a is operated by providing the lower inclined portion 33c near the lower end of the groove portion 33a. The tip of the sickle portion 19a is removed from the receiving portion 32b by rotating 45 degrees at an early stage. Further, by forming the lower end of the lower inclined portion 33c slightly longer in the vertical direction, the sickle portion 19a of the door-end lock 19 is difficult to turn (hard to open), thereby improving crime prevention.

  Further, the slider 23 is provided with an inclined groove (inclined portion) 17 for guiding the operation shaft portion 16c in order to push the kicking member 16 to the vertical frame 2c side by sliding the slider 23 downward from above. . By the way, when the door lock 19 is locked by the operation unit 18 with the shoji 4 opened, the sickle portion 19a is in an empty state protruding from the end surface of the door rod 6d, and when the shoji 4 is closed in this state, the sickle portion 19a is The receiving member 32 (or the vertical frame 2c) may collide and be damaged. In order to solve this problem, only when the shoji 4 is closed, that is, only when the kicking member 16 is pushed from the kicking position, the door lock 19 can be locked by the operating portion 18. It is configured. The kick-out member 16 is a trigger that enables the locking operation by the operation portion 18 only when the kick-out member 16 is pushed in by closing the shoji 4.

  When the kicking member 16 is protruding, the slider 23 cannot be moved upward from below, and when the kicking member 16 is pushed in, the slider 23 can be moved upward from below. The groove 17 is formed as a one-way rotary groove having a return passage 34. The return passage 34 includes a first guide groove 34a that is arcuate about the horizontal or support shaft 21 that guides the operation shaft portion 16c from the upper end portion (terminal portion) of the inclined groove 17 in the pushing direction of the kick member 16, The first guide groove 34a is formed of a substantially vertical second guide groove 34b that connects the end portion of the first guide groove 34a and the lower end portion (start end portion) of the inclined groove 17. The rotary groove is formed in a substantially right triangle shape having the inclined groove 17 as a hypotenuse.

  Further, in order to restrict the movement of the operating shaft portion 16c of the kicking member 16 to one-way, the inclined groove 17 excluding the upper end portion, and from the start end portion of the first guide groove 34a to the substantially intermediate portion of the second guide groove 34b. Is a deep groove, and a shallow groove is formed from a substantially middle portion to a lower end portion (terminal portion) of the second guide groove 34b, and an inclined surface 35 connecting the deep groove and the shallow groove to a substantially middle portion of the second guide groove 34b. An inclined surface 36 is formed at the end portion of the inclined groove 17 and is inclined upward toward the starting end portion of the first guide groove 34a. The end of the inclined surface 36 at the end of the inclined groove 17 is a precipitous wall, so that the operation shaft portion 16c moved from the inclined groove 17 to the first guide groove 34a does not return to the inclined groove 17.

  The kick-out member 16 is urged by the torsion spring 31 so that the operation shaft portion 16 c contacts the bottom surface of the inclined groove 17 and the return passage 34. Further, inside the inclined groove 17 and the inner side of the first guide groove 34a, the operation shaft portion 16c is prevented from falling off the inclined groove 17 and the first guide groove 34a when a force is applied to the kicking member 16. Further, it is preferable that flanges 37 and 38 to be engaged with the flange 16b of the operation shaft portion 16c are provided.

  In the above configuration, as shown in FIG. 13A, in the state where the shoji 4 (or 3, the same applies hereinafter) is closed and the door lock 19 is locked, the slider 23 is in the upper position, thereby kicking. As shown in FIG. 15A, the operation shaft portion 16c of the ejecting member 16 is positioned at the lowermost end of the inclined groove 17, and the kicking member 16 is in the storage position. Further, the operation unit 18 is located at an upper position in the handle part 25 and closes the handle part 25, whereby it is possible to easily confirm at a glance that the door lock 19 is in a locked state. Further, in this state, it is impossible to put the hand on the handle part 25, so that it is possible to prevent the shoji 4 from being accidentally opened.

  Next, when the shoji 3 or 4 is opened, when the operation unit 18 is opened (sliding operation from the upper position to the lower position) by placing a finger on the finger hooking portion 18a of the operation unit 18, the slider 23 moves downward. As a result, the sickle portion 19a of the door lock 19 is rotated in the unlocking direction via the guide groove 33 and the operation shaft portion 19c, and the kicking member 16 is moved vertically through the inclined groove 17 and the operation shaft portion 16c. It is pushed out to the 2c (or 2d) side (see FIGS. 13B and 14A). As a result, the door lock 19 is unlocked, and the kicking member 16 kicks the receiving portion 32c of the vertical frame 2c to lighten the shoji 4 to a position where the door rod 6d is separated from the airtight material 13 of the vertical frame 2c. It can be easily moved open by force. That is, the unlocking operation of the door lock 19 and the opening operation of the assist mechanism 15 can be performed at the same time by the opening operation of one operation unit 18, which is easy to use and improves the operability.

  In the assist mechanism 15, the slider 23 is moved about 4 cm in the vertical direction (vertical direction), and the kicking member 16 is pushed out about 8 mm in the lateral direction by the wedge action by the inclined groove (inclined portion) 17. , About 5 times more power can be produced. In addition, the kicking member 16 can further increase the pressing force due to the lever principle based on the ratio of the length from the support shaft (support point) 21 to the operation shaft portion (force point) 16c and the pressing portion (action point) 16e. In other words, the operation force of the operation unit 18 can be further reduced, and the operation unit 18 can be downsized.

  The operation unit 18 is configured to be slid up and down in parallel with the indoor surface of the door toe 6d, and the interior side portion of the operation unit 18 or a member that houses the operation unit 18 (the pulling unit 25 in the illustrated example) is the above-described operation. When the unit 18 is attached to the outer shoji 4, it is provided at a position where it does not interfere with the outdoor portion of the inner shoji 3 (preferably, the operating unit 18 does not project or projects from the indoor surface of the door toe 6d. Unlike the conventional assist handle, the operation unit 18 provided on the door toe 6d of the shoji 4 and the shingling 3 are different from each other. The inside and outside shojis 3 and 4 can be brought apart without interfering with each other, and the design can be improved. Further, when the operation unit 18 is moved from the upper closed position to the lower open position, the opening 25a on the front surface of the handle portion 25 that has been blocked up to now is opened. Can be easily opened (see FIG. 13C).

  Thus, when the shoji 4 is opened, the kicking member 16 is held by the torsion spring 31 so as to protrude to the kicking position. When the slider 23 moves from the upper position to the lower position, the kicking member 16 moves the operation shaft portion 16c from the lower end portion (start end portion) to the upper end portion (end portion) of the inclined groove 17 [FIG. ) To (b)], and the movement causes the support shaft 21 to pivot about the fulcrum in the kick-out direction. When the operating shaft portion 16c gets over the inclined surface 36 at the end portion of the inclined groove 17 and reaches the start end portion of the first guide groove 34a, the operating shaft portion 16c can move in the first guide groove 34a. The kicking member 16 tries to return to the side opposite to the kicking direction by its own weight, but this is prevented by the biasing force of the torsion spring 31, and the kicking member 16 is held in the kicked state [FIG. c)].

  In this state, if the operation portion 18 is to be operated from the lower position to the upper position in order to lock the door lock 19, the operation shaft portion 16 c of the kicking member 16 gets over the inclined surface 36, and thus the first guide It cannot return to the inclined groove 17 side from the start end portion of the groove 34a, so to speak, it works as a stopper, so that the slider 23 and the operation portion 18 cannot be moved upward, and the sickle portion 19a of the door lock 19 is Since it cannot be rotated in the locking direction, it is possible to prevent the door lock 19 from being hung and to prevent damage to the sickle portion 19a of the door lock 19 that occurs when the shoji 4 is closed in the hung state. And durability can be improved.

  On the other hand, when the shoji 4 is closed, as shown in FIG. 14A, the kicking member 16 first comes into contact with the receiving portion 32c of the vertical frame 2c, and the kicking member 16 resists the biasing force of the torsion spring 31. It is pushed into and stored in the tip 6d (in the case portion 22) [see FIG. 14 (b)]. At this time, as shown in FIGS. 15C to 15D, the operation shaft portion 16c of the kicking member 16 moves in the first guide groove 34a from the start end portion toward the end portion, and the second guide groove The slider 23 and the operation unit 18 can be moved upward (by a function as a trigger). That is, only when the shoji 4 is closed, the operation portion 18 can be closed (sliding operation from the lower position to the upper position), and the door lock 19 can be locked.

  Accordingly, when the operation portion 18 is opened, the operation shaft portion 16c of the kicking member 16 is halfway from the deep groove start end along the second guide groove 34b as shown in FIGS. 14 (c) to 15 (e). The inclined surface 35 moves to the end of the shallow groove, and as shown in FIGS. 13 (a) to 15 (a), the inclination of the deep groove which is the first position from the end of the second guide groove 34b is further increased. It moves to the start end of the groove 17 and stops. At this time, since the operation shaft portion 16c of the kicking member 16 moves along the vertical second guide groove 34b, the kicking member 16 is kept in the stored state. Further, when the operation shaft portion 19c of the sickle portion 19a of the door lock 19 is moved along the guide groove 33 by the upward movement of the slider 23, the sickle portion 19a is rotated in the locking direction, so that the sickle portion 19a is a vertical frame. It hooks on the receiving part 32b of 2c, and will be in a locked state. Next, when the operating portion 18 and the slider 23 are moved downward to unlock the door lock 19, the operating shaft portion 16 c of the kicking member 16 moves from the end of the shallow groove of the second guide groove 34 b to the inclined groove 17. Since it has moved to the start end of the deep groove, the operation shaft portion 16c can move along the inclined groove 17 without returning to the second guide groove 34b.
