Description

  The present invention relates to a blind built-in type multiple glass sash having a built-in blind between a plurality of window glasses spaced apart inside the sash, and more specifically, a blind built-in type multiple glass sash blind that raises and lowers a slat of the blind. The present invention relates to a lifting device.

  In the multiple glass sash in which a plurality of window glasses are arranged inside and outside the sash, there is a built-in blind multiple glass sash in which a blind is built in a space portion separating the two window glasses. In the type that can raise and lower the slat of the blind, the slat and the blind lifting device are connected by a lifting cord, and the blind can be moved to the fully open or fully closed or any open position by raising or lowering the slat with the blind lift device. I have to.

  As a blind elevating device for a built-in blind type multiple glass sash, for example, a vertical guide slit is provided in one side frame of the sash frame, and a sliding member is used in this side frame, and it can be slid in the vertical direction. A lifting operation knob that can be fixed at the position of the blind, the lifting cord connected to the bottom rail of the lower end of the blind is directed vertically upward to the upper end of the slat row, and is guided horizontally in the upper frame of the sash frame, The upper frame is extended to near one end, and is guided vertically downward in the one side frame, and the guide that moves up and down in the one side frame by the lifting operation knob is wrapped around the upper frame. The upper end of the sash frame is fixed inside the sash frame (see, for example, Patent Document 1), and a vertical axis is provided inside the side frame of the sash frame, and a slider is inserted into the side frame so as to be movable up and down. A position where a lifting / lowering cord for lifting / lowering a slat of a blind is connected to the slider, a rack having a number of flat teeth is attached to the side frame in the vertical direction, and the slider is engaged with a locking portion of the locking body. A lock member that can be moved to a position where the lock member is released, an operating lever that operates the lock member, and a rotary member that can be rotated and reciprocated to rotate the vertical axis, and is moved forward to a position where the lock member is released. A configuration is known in which a stop holding release mechanism that releases the holding of the lock member by holding and returning is attached, and a buffer mechanism that slows the moving speed of the slider upward is known (for example, Patent Documents). 2).

Japanese Examined Patent Publication No. 4-24517 (first page, FIGS. 3 and 6) Japanese Patent No. 2631915 (first page, second page, FIG. 2, FIG. 9, FIG. 13)

  The lifting device of Patent Document 1 has the convenience that the configuration is relatively simple. However, when the blind is fully opened or fixed at an arbitrary open position, the load acting from the slat is held by the lifting operation knob. While supporting, two operations of screwing and loosening the knob for lifting operation are necessary at the same time. The two operations are the same when the blinds are fully opened or when the open state is changed from any position. Especially when the lifting control knob in the fixed state is easily loosened, the slats reach the fully closed position by their own load. As a result, the slats are individually tilted by the impact and the lifting and lowering cords and the ladder cords are entangled with each other, and there is a risk of causing an accident such as a finger being flipped by a lifting and lowering operation knob that lifts the guide slits at once. As described above, the lifting device of Patent Document 1 requires skill for opening and closing the blinds, and is particularly difficult to handle for children and women.

  Further, in Patent Document 1, in order to fix the lifting operation knob at an arbitrary height of the side frame, the indoor side plate of the side frame positioned on both sides of the guide slit is sandwiched from inside and outside by the lifting operation knob and the sliding member. Therefore, the impression by the knob for raising / lowering operation is left on the indoor side plate surface of the side frame, and the commercial value is lowered.

  In Patent Document 2, as an elevating device, in addition to a slider that moves up and down the side frame of a sash frame, an operating lever, a lock member, a rack that engages and disengages a lock piece of the lock member, an arc groove, a guide pin, and a support member of the lock member. A shaft, a spring that holds the engagement between the lock piece and the rack, a stop release button of the stop holding release mechanism, a horizontal axis for the stop release button, a conical portion and a large diameter portion of the horizontal axis that engages and disengages the claw piece of the lock member , Since many parts such as a spring for holding the engagement between the claw piece and the large diameter portion are required, it is disadvantageous in terms of production and cost.

  Furthermore, the lifting and lowering device of Patent Document 2 has a structure that is more complicated because the stop and hold release mechanism has the same structure as the slat tilting mechanism, and the vertical axis of the slat tilting mechanism and the bevel gear mechanism are integrally incorporated. In addition, since the slat tilting mechanism, which is essentially unnecessary for raising and lowering the blinds, is also raised and lowered integrally, the raising and lowering operation is heavy and lacks smoothness, and there is a concern about unnecessary troubles.

  The present invention has been made in the background of such a situation, and the object is to achieve both a simple configuration and simplification of operation, and anyone with a built-in blind that can be easily operated by one touch. The object is to provide a blind elevating device for multiple glass sashes at low cost.

To achieve the above object, the present invention is arranged to separate the plurality of window glass inside the room outside of the sash frame, arranged blind in the space defined between the window glass, the the lifting cord leading to the blind slats and connected to the blind lifting device mounted within either of the side frame of the sash frame, the blind embedded multiplexing glass so as to lift the slats in operation of the blind lifting device In the sash blind lifting device,
The blind lifting device is
A guide slit opened in the vertical direction on the indoor side of the one side frame;
A slider that connects the elevating cord and moves up and down the one side frame;
Is pivotally supported a proximal end to said slider, a blind lifting lever disposed rotatably to the room outward grip operation of the front end side from the guide slit is protruded toward the cabin,
A brake shoe that is slidably received into the room outward inside the slider base end portion inside of the blind lifting lever,
A cam member provided at the base end of the blind lift lever so as to be able to contact the brake shoe;
A rolling roller provided on the slider for rolling the inner wall of the one side frame to guide the raising and lowering of the slider;
A resilient means for urging the brake shoe in a direction that always separates from the inner wall of the one side frame ;
The blind lifting lever when pivoted to a lift stop position, the cam member is rotated integrally with the blind lifting lever pushes the brake shoe to the outside direction, the resilient means the brake shoe Against the inner wall of the one side frame against the urging force , maintaining the slider in a locked state,
Upon rotating the blind lifting lever to lift possible position, the cam member is maintained in the released state by releasing the pressing of the outdoor direction of the brake shoes by rotating integrally with the blind lifting lever , said brake shoe from the inner wall of the one of the side frame is separated by the biasing force of said resilient means, is characterized in that allowed the lifting of the slider.

Further, the grip operation of the blind lifting lever, a state of being rotated to a position one of the side frame substantially perpendicular to said vertically movable position, grip the operation portion of the blind lifting lever, chamber of the one of the side frame a state of being rotated to a position substantially along the side surface and the elevation stop position. Furthermore, the slider of the present invention, Keru set rolling roller for guiding the vertical movement of the slider to roll the inner wall of one of the side frame. Further, the blind elevating device of the present invention is provided with a resilient means, and this resilient means always urges the brake shoe in a direction away from the inner wall of one side frame.

  In the blind lifting device of the present invention, the blind lifting lever pivotally supported by the slider at the base end is rotated in the indoor / outdoor direction to lock the slider in a desired position or lift and lower the lock. The blind is opened and closed by rotating the blind lift lever to the lift stop position and locking the slider to an arbitrary position, thereby maintaining the blind in the desired open position (or closed position) and raising and lowering the blind. By opening and closing the slider by rotating the lever to the up and down position, the opening and closing state of the blind can be adjusted.

  For example, when the blind elevating lever is rotated to the elevating stop position, the cam member rotates integrally with the blind elevating lever to push the brake shoe outward, and the brake shoe is moved to the inner wall of one side frame. The slider is kept in a locked state by pressure contact, and the blind is fully opened or fully closed, or kept in an arbitrary open position.

  Also, when the blind lift lever is rotated to the position where it can be lifted, the cam member rotates integrally with the blind lift lever to release the brake shoe from pushing outward, and the brake shoe is moved to one side frame. The slider can be moved up and down apart from the inner wall.

  From this state, when the slider is raised, the lifting / lowering cord loosens to the blind side, and the slats gradually spread downward to close the blind, while when the slider is lowered, the lifting / lowering cord is drawn to one side frame side, Is folded upward and the blinds are opened.

  Then, when the blind lift lever is rotated again to the operating position, the cam member pushes the brake shoe outward, the brake shoe presses against the inner wall of one side frame, and the stopped state of the slider is maintained. Any open or closed state of the blind is maintained.

The blind raising / lowering lever, brake shoe and cam member are provided on the slider. When the slider moves up and down, the grip operating part of the blind raising / lowering lever is gripped to raise and lower the brake shoe, cam member and slider integrally.

  The raising / lowering position and the raising / lowering stop position can be set in any way, but the grip operating part of the blind raising / lowering lever is rotated to a position substantially along the interior side surface of one side frame (ie, vertical state) Similarly, the difference between the two forms in which the direction of the grip operating part of the blind elevating lever rotated to a position substantially orthogonal to one side frame (that is, the horizontal state) is completely different from the elevating position and elevating stop. The position is preferable because visual recognition can be easily performed.

  Further, since the blind lifting lever is assembled to the slider and the slider is operated by gripping the blind lifting lever grip operating portion, the blind lifting lever grip operating portion is substantially the same as one side frame. The state rotated to an orthogonal position is set as a liftable position, and the grip operating part of the blind lift lever is set as a lift stop position when it is rotated to a position substantially along the indoor side surface of one side frame. More preferable in operation.

  By providing a rolling roller in the blind lifting device of the present invention, the lifting and lowering operation of the slider can be performed lightly and smoothly.

Further, the resilient means used in the blind lifting device of the present invention is provided so as to constantly urge the brake shoe in a direction away from the inner wall of one side frame. Then, when the blind lift lever is rotated to the lift stop position, the cam member presses the brake shoe against the inner wall of one side frame against the biasing force of the elastic means, and the blind lift lever is rotated to the liftable position. When it moves, the resilient means pushes the cam member and the brake shoe back toward the room and separates the brake shoe from the inner wall of one side frame. The slider is lifted and lowered in a state where the brake shoe is separated from the inner wall of one side frame, so that the brake shoe is not unnecessarily reduced and a smoother lifting and lowering operation can be performed. As a material of the elastic means, a spring material such as a disc spring, a compression coil spring, and a tension coil spring, rubber, or a soft synthetic resin is suitable.

  According to the blind built-in type multiple glass sash blind raising / lowering device of the present invention, the blind can be easily opened and closed by raising or lowering the slider with a one-touch operation by simply rotating the blind raising / lowering lever to the raising / lowering position. It is possible to stop the slider at an arbitrary position and maintain the blind in a desired open state or closed state by a one-touch operation by simply rotating the lift lever to the lift stop position. Therefore, anyone can easily open and close the blinds with one touch. Furthermore, since the structure is simple, it can be provided at a low cost and can be expected to withstand long-term use.

  In addition, a state where the grip operating part of the blind lifting lever is rotated to a position substantially orthogonal to one side frame is set as a liftable position, and the grip operating part of the blind lifting lever is substantially along the indoor side surface of one side frame. Since the lifted / lowered position is easily identified by visual inspection, the blind lift lever protrudes perpendicularly to the indoor direction at the liftable position. It has excellent operability when opening and closing the blinds, and since the blind lifting lever is housed along the side frame at the lifting stop position, it is possible to avoid impacts such as erroneous operation and contact.

  Further, by providing a rolling roller in the blind lifting device of the present invention, the lifting and lowering operation of the slider can be performed lightly and smoothly. Furthermore, by always urging the brake shoe in a direction away from the inner wall of one side frame by using the elastic means, the durability of the brake shoe can be improved and the durability of the slider can be improved. It can be raised and lowered smoothly.
