JP6727646B2 - Pulling device for sliding window - Google Patents

Description

The present invention relates to a sliding window in which a shoji attached rotatably to a window frame can be opened and closed by turning an operation handle of an operator (window opening/closing device), and when the shoji is closed, the shoji is drawn to the window frame side. The present invention relates to a sliding window pulling device that is made possible.

An operator (window opening/closing device) having an operation handle protruding to the inside of the room is attached to the window frame, and a sliding window is known in which the shoji is opened and closed by an output arm that is rotated by this operation handle. A vertical sliding window in which a shoji screen rotates about a vertical rotating shaft and a lateral sliding window in which a sliding screen rotates around a horizontal rotating shaft are widely used. As the sliding-out window as described above, there is known a sliding-out window in which the sliding door is pulled toward the window frame side or locked when the sliding door is rotated to the closed position (see, for example, Patent Documents 1 and 2). In the device shown in Patent Document 1, the tip of a first arm that is rotated by an operating handle of an operator is pivotally attached to an intermediate portion of a second arm, and both ends of the second arm are arm supporting members provided on a shoji screen. The sliding doors are slidably connected to the arm support members provided on the window frame, and the first arm is moved to pull the second arm toward or away from the window frame to open or close the shoji screen. The lock member provided at the tip of the second arm on the window frame side is configured to rotate and engage with the engaging member provided on the shoji when the shoji is closed. However, since the lock member is provided at the tip of the second arm that linearly moves along the elongated hole, and the linear motion of the lock member is converted into the rotary motion when the shoji is closed, the lock member has a linear motion and a rotary motion. The timing of combination is delicate.Specifically, in order to rotate the lock member, an elongated hole having a chevron portion is formed in the arm support member on the window frame side, or the contact pin with which the lock member abuts is placed at the optimum position. Since it is necessary to rotate the lock member accurately in accordance with the closing timing of the shoji screen, it is difficult to adjust the timing, and the structure is complicated and economically difficult to obtain.

The opening device described in Patent Document 2 rotates a connecting arm by an operation arm (output arm) of an operator, rotates an opening/closing arm by the connecting arm to open/close a shoji, and moves a slide body by the connecting arm. The engaging piece provided on the slide body is configured to engage with the engaging pin provided on the shoji. However, since a connecting arm is required in addition to the operation arm and the opening/closing arm, the number of parts is large, and the horizontal pin of the connecting arm has a long hole for opening/closing operation of the opening/closing arm located outside the room and a long length for locking operation. Since the structure is slid into the hole, there is a risk that the operation may become uncertain due to dust adhesion or the like. Further, in order to engage the hooking piece of the slide body with the hooking pin of the shoji, it is necessary to further rotate the operator to move the slide body after closing the shoji. If the operator stops the rotation operation on the assumption that the pulling (locking) has been completed, the latching piece and the latching pin may not engage with each other, or the engagement may become unreliable, so it is not reassuring.

JP 2004-76452 A (paragraph 0037, FIG. 4) Japanese Patent No. 4911021 (paragraph 0018, FIGS. 4 to 6)

The present invention, as described above, in a sliding window in which a shoji suspended in a window frame in a rotatable manner is opened and closed via an arm by an operator, the construction is simple and when the shoji is closed by the operator, It is an object of the present invention to provide a pulling-out device for a sliding window, which is capable of reliably pulling a shoji screen toward the window frame side.

According to the present invention, in a sliding window provided with a frame, an operator attached to the frame, and a sliding door rotatably attached to the frame so as to be closed or opened by the operation of the operator, The operator has an operation handle projecting from the operator main body to the indoor side, and an output arm rotatably provided at a closed position along the frame and an open position slid from the frame by the operation handle and projecting to the outside of the room, The shoji includes a shoji bracket provided on a frame, a shoji slider slidably incorporated in the shoji bracket, a shoji arm having one end connected to the shoji slider, and a hooking portion provided on the side surface of the frame body. The output arm has a tip connected to an intermediate portion of the shoji arm, and the frame body is provided with a main body bracket having an opening on the side, and the main body bracket has the other end of the shoji arm. And an outer slider that is slidably provided along the body bracket and that is supported by the inner slider and that has an outer rack gear and that is slidable along the body bracket. A pinion gear that meshes with the outer rack gear of the outer slider is provided in the main body bracket, and a main body rack gear that meshes with the pinion gear is provided in the main body bracket during movement of the inner slider when moving toward the opening. When the inner slider moves toward the opening of the main body bracket, the pinion gear meshes with the main body rack gear to further move the outer slider, and the tip of the outer slider protrudes from the opening of the main body bracket to lock the shoji. A pulling device for a sliding window is provided, which is characterized in that the pulling device is adapted to be engaged with a portion, and the above problems are solved.

According to the present invention, the pinion gear is for the sliding window in which some of the teeth meshing with the outer rack gear are missing so as to stop the movement when the outer slider protrudes to a position where the outer slider engages with the hooking portion. A retractor is provided.

Also, according to the present invention, there is provided the sliding window pulling device in which the shoji slider is detachably fitted to the shoji bracket .

The present invention is configured as described above, and when the operator's operation handle is rotated, the shoji arm rotates via the output arm, and the shoji can be gradually moved to the frame side. With the rotation of the shoji arm, the inner slider connected to the tip of the shoji arm starts to move toward the opening in the body bracket. Since the outer slider is movably supported by the inner slider, the outer slider moves in the opening direction together with the inner slider.However, if the pinion gear meshes with the main body rack gear and rotates during the movement, Through the outer rack gear meshing with the pinion gear, the outer slider moves toward the opening with a movement amount greater than the movement amount of the inner slider, and starts to protrude from the opening of the body bracket. If the shoji turns near the closed position during this time, the amount of movement of the shoji and the inner slider until reaching the closed position decreases, but as described above, the movement of the shoji and inner slider is larger than that of the inner slider. Since the one slider is configured to move, the tip of the outer slider can be securely engaged with the hooking portion of the shoji, and the shoji can be pulled toward the frame body side. Further, in the pulling device of the present invention, since the arm is composed of only the output arm and the shoji arm, the number of parts is small, and in addition, the inner slider and the outer slider moved by the shoji arm are Since it is configured to move linearly in synchronization with the closing movement, it is easy to set the timing.

Further, when the outer slider protrudes to a position where it engages with the hooking portion of the shoji screen, if a part of the teeth of the pinion gear that meshes with the outer rack gear is cut out so as to stop the movement, it will reach the closed position. When moved, the outer slider can be prevented from further projecting, and the engagement with the hooking portion can be prevented from being hindered. If the shoji arm and shoji slider are detachably connected, it is convenient because the arm can be easily removed for cleaning the outer surface of the shoji.

Although the present invention can be applied to vertical sliding windows, FIG. 1 shows a part of horizontal sliding windows. As shown in Patent Document 1 and widely known, the lateral sliding window is provided with a rectangular frame body having an upper frame, a lower frame and left and right vertical frames, and a hanging metal fitting on the vertical frame of the frame body. It has a shoji that has a rotating shaft in a horizontal direction and is attached so that it can be opened and closed and can be slid out. In FIG. 1, a part of the lower frame of the frame body 1 and a part of the lower frame of the shoji frame 2 are shown. The lower frame 1 is provided with an operator (window opening/closing device) 3 and On the side surface of the lower frame 2 of the shoji screen, a hooking portion 4 having a hooking hole 4a is provided. The configuration of the operator 3 is basically the same as the widely known configuration, and the inner tip portion of the operation handle 5 projecting obliquely from the operator body 6 toward the room is provided inside the operator body 6. When the operation handle 5 is rotated by being connected to an operation shaft (not shown), the output arm 7 is connected to the operator body 6 via a worm gear (not shown) pivotally mounted in the operator body. It is configured to be rotatable in a horizontal state between a closed position along the line and an open position protruding to the outside of the room.

The tip of the output arm 7 of the operator 3 is connected to the intermediate portion of the shoji arm 8 by a pivot 9. One end of the shoji arm 8 is slidably connected to the lower surface of the lower frame 2 of the shoji, and is preferably detachably connected by an appropriate connecting structure.

The shoji bracket 10 has side frames 12 standing upright on both sides of the substrate 11, an edge frame 13 provided on the tip side of the side frame, and a sliding groove 14 having an opening between the edge frames. In the embodiment shown in FIG. 1, the shoji bracket is formed separately from the lower frame, but it can also be formed integrally. A sliding door slider 15 is slidably fitted in the sliding groove 14.

The shoji slider 15 has a base end slider 17 having an engaging edge 16 that is inscribed in the edge frame 13 on one side frame side, and a step portion at the tip of a support shaft 18 whose one end is fixed to the base end slider 17. A slider spring shaft 19 having a small diameter extending in the lateral direction through the through hole 20, a through hole 20 into which the support shaft 18 is recessed, a receiving hole 21 into which the tip of the slider spring shaft 19 is inserted, and the edge frame 13 on the other side can be inscribed. The movable slider 23 having the engaging edge 22 is provided, and the engaging edges 16 and 22 are fitted into the sliding groove 14 in the state of being engaged with the edge frame 13, respectively. The length of the slider spring shaft 19 is formed such that when the shoji slider 15 is fitted into the shoji bracket 10, the tip of the slider spring shaft 19 is located inward of the facing edge frame 13. The base-side slider 17 and the moving-side slider 23 are urged by slider springs 24 provided around the slider spring shaft 19 in the directions in which the engaging edges are slidably engaged with the opposing edge frames. The tip of the shoji arm 8 is rotatably connected to the moving slider 23 by a pivot 25.

In a normal state, the slider spring 24 presses the proximal-side slider 17 and the moving-side slider 23 in a direction in which their respective engaging edges engage with the edge frame of the side frame, so that the proximal-side slider 17 and the moving-side slider 23 As shown in FIGS. 2B and 2C, a gap is formed between the inner ends of 23, and in this state, the shoji slider 15 can slide along the shoji bracket 10 in the longitudinal direction. Then, when the moving side slider 23 is pulled toward the proximal slider 17 side through the shoji arm 8 in the direction in which the gap is eliminated, the engaging edge 22 of the moving side slider 23 is disengaged from the edge frame 13 of the shoji bracket 10. As a result, since a gap is formed between the outer end of the moving slider 23 and the edge frame 13, the moving slider 23 and the proximal slider 17 can be pulled out from the opening of the sliding groove 14, and the sliding door slider The shoji arm 8 can be removed from the shoji by removing 15 from the shoji bracket 10.

A substantially L-shaped connecting piece 26 is attached to the other end of the shoji arm 8 by a pivot 27, and the connecting piece 26 has an inner slider 28 movable along the lower frame 1 provided with the operator body 6. Are connected by a connecting shaft 29. In order to hold the inner slider 28, a body bracket 30 made of a metal material such as lip channel steel is fixed to the lower frame 1. With reference to FIG. 3, the main body bracket 30 is placed in a state of being opposed to the upper frame 33 and the lower frame 34 that extend in the horizontal direction above and below the substrate 32 provided with the mounting holes 31, and the end edges of the upper frame 33 and the lower frame 34. A sliding groove 37 is formed which has an upper flange 35 and a lower flange 36 which are projected, and which is open between the upper and lower flanges. An opening 38 is formed on the side of the body bracket 30, and the inner slider 28 slides on the lower frame 34 with the lower portion inscribed in the lower flange 36 in FIG. It is slidably fitted in the moving groove 37. The inward slider 28 is stopped at the left open position of the body bracket 30 in FIG. 1 when the shoji is opened, and is directed toward the right closed position of the body bracket 30 when the shoji is closed. To move.

A pinion gear 39 is rotatably attached to the inner slider 28 by a pivot 40. A main body rack gear 41 that engages with the pinion gear is provided on the edge of the lower flange 36 on the opening 38 side. The main body rack gear 41 is not provided over the entire length of the lower flange 36, and when the inner slider 28 moves from the open position to the closed position in the direction of the opening 38 by a predetermined distance, the main body rack gear 41 is moved midway. Tooth 41 is formed with teeth so that the pinion gear 39 meshes with it.

A mounting portion 42 extending in the longitudinal direction via a step is formed on the upper part of the inner slider 28, and an outer slider 43 is slidably mounted on the mounting portion 42. A front surface of the outer slider 43 is in sliding contact with the inner surface of the upper flange 35, and a lower portion thereof is in sliding contact with the mounting portion. An elongated hole 45 having an engaging edge portion 44 formed at an opening edge and extending in the longitudinal direction is formed in an upper portion of the outer slider 43, and is slidably engaged with the engaging edge portion 44 through the elongated hole 45. A guide pin 47 having a matching head 46 is inserted, and the tip of the guide pin 47 is fixed to the inner slider 28 to hold the outer slider 43 so as not to fall off the inner slider 28.

At the tip of the upper portion of the outer slider 43, there is formed an engaging protrusion 48 having an inclined surface in the direction of pulling the shoji to the frame side when closing the shoji. In the outer slider 43, a protruding portion 49 is formed in a portion located on the front side (side surface side provided with the pinion gear) in FIG. 3 with respect to the portion slidingly contacting the placing portion 42, and the lower surface thereof has An outer rack gear 50 that engages with the pinion gear 39 is provided. It should be noted that a gap is formed between the teeth of the outer rack gear 50 and the tip of the connecting piece 26 to such an extent that the movement of the outer slider 43 is not hindered.

With the above configuration, the pinion gear 39 meshes with the outer rack gear 50 of the outer slider 43 when the inner slider 28 is in the open position. When the inner slider 28 moves toward the closed position, the outer slider 43 also moves, and the pinion gear 39 provided on the inner slider 28 is formed on the lower flange 36 of the main body bracket 30 during the movement. When they come into contact with the main body rack gear 41, they mesh with each other. Since the inner slider 28 is moving with the rotation of the shoji in the closing direction, the pinion gear 39 rotates, and the rotation of the pinion gear causes the outer slider to move more than the moving amount of the inner slider. To do. The amount of movement of the outer slider at this time is
Outer slider movement amount = Inner slider movement amount + Pinion gear rotation angle x (Pinion gear pitch circle diameter x π/360)
Becomes

In this way, the outer slider 43 moves toward the opening 38 of the main body bracket 30 on the inner slider 28 via the outer rack gear 50 engaged with the pinion gear 39, and during this time, the screen 4 for engaging with the screen 4 Moves to a position facing the opening 38 of the body bracket 30. During this movement, when the engagement protrusion 48 at the tip of the outer slider 43 protrudes to a position where it engages with the hooking portion 4, the pinion gear 39 is provided with one tooth so that the outer slider 43 does not move further. A cutout portion 51 is provided by missing the portion.

In the state shown in FIGS. 1 and 5 in which the shoji screen is open, when the operation handle 5 of the operator 3 is rotated, the tip of the output arm 7 begins to rotate in a direction approaching the lower frame 1, and the shoji arm 8 has both ends thereof. Slides and the shoji (lower frame 2) rotates toward the closed position. The inner slider 28 connected to one end of the shoji arm 8 is pushed by the shoji arm 8 and moves toward the opening 38 of the body bracket 30. At this time, since the pinion gear 39 and the outer rack gear 50 are in mesh with each other, the outer slider 43 mounted on the inner slider 28 moves together with the inner slider 28.

When the pinion gear 39 meshes with the main body rack gear 41 during the movement, the pinion gear 39 rotates. By this rotation, the outer slider 43 is largely moved on the inner slider 28 toward the opening 38 via the outer rack gear 50. When the shoji screen approaches the closed position, the amount of movement of the shoji screen and the inward slider decreases from just before closing to full closure, but as described above, the outer slider 50 moves larger than the moving amount of the inner slider 28. Therefore, when the hooking portion 4 provided on the shoji moves to a position facing the opening 38 of the body bracket 30, the engaging protrusion 48 of the outer slider 43 is inserted into the receiving hole 4a of the hooking portion 4. By engaging, the shoji can be pulled toward the lower frame 1 (see FIG. 6). Since the notch 51 of the pinion gear 39 faces the outer rack gear 50 when the engaging protrusion 48 at the tip of the outer slider 43 engages with the hook 4, the outer slider 43 is It is possible to prevent it from protruding from the opening more than necessary.

When the operation handle 6 of the operator 3 is rotated in the opposite direction from the closed state of the shoji screen, the output arm 7 is rotated in a direction in which the tip end is separated from the lower frame 1, and the inward slider 28 is opened via the shoji arm 8. The outer slider 43 also moves toward the open position through the pinion gear 39 and the outer rack gear 50, and the engagement protrusion 48 and the hooking portion 4 are disengaged. Rotates towards the open position. When the shoji is in the open position, if the tip of the shoji arm 8 on the shoji side is laterally moved in the side frame direction of the shoji bracket 10, the shoji slider 15 can be removed from the shoji bracket 10. Therefore, the outer surface of the shoji is cleaned. Etc. are easy.
