Description

  The present invention relates to an electric elevating window apparatus installed in a window opening / closing opening such as an outpatient acceptance opening.

  As a conventional electric lift window device, a lift window having a sash window structure is suspended by a pair of left and right suspension wires of a hoisting machine on both upper sides, and the lifting wire is wound and unwound by the hoisting machine. A device configured to open and close the window is already known. In such an electric elevating window device, the elevating window is suspended by setting the left and right suspension wires hanging from the winding drum of the hoisting machine to the same length.

  The above prior art is a technique generally known to those skilled in the art, and does not relate to a known literature invention.

  Since the conventional electric lift window device is constructed as described above, it can be said that the upper and lower sides of the lift window are suspended by making the suspension wire from the winding drum the same length on the left and right at the time of manufacture. When the installation window is installed on the site, the elevator window may be inclined in the vertical direction, and either one of the right and left sides of the elevator window may be lowered, or the suspension wire may be elongated due to long-term use. In particular, when the above-mentioned shoulder fall occurs, in order to correct the shoulder fall and obtain the level of the lifting window, after removing the lifting window from the hanging wire, the left and right hanging wires are cut to the same length. Such a work for correcting the lowering of the shoulder of the lifting window requires a lot of labor, and there is a problem that it is difficult to correct and adjust especially the lowering of the lowering of the lifting window. It is also conceivable that the lifting window is hung with an independent chain on the left and right. In this case, when the shoulder of the lifting window is lowered, one piece of the chain can be packed at the lifting window hanging source of the chain. However, since the chain cannot be packed by a length shorter than the one frame, there is a problem that the shoulder descent cannot be corrected and adjusted even in the lifting window suspended by the chain.

  The present invention has been made to solve the above-described problems, and finely adjusts the chain to a length shorter than the length of one frame while the lifting window is suspended by a pair of left and right independent chains. An object of the present invention is to provide an electric lifting window device that can be easily prevented from descending the shoulder of the lifting window.

  An electric lift window device according to the present invention is a pair of guide rails, a pair of sprockets disposed above the guide rails and driven to rotate synchronously by a window lift drive system switch, and meshed with the sprockets. Left and right window suspension chains hanging in the guide rails, lifting windows suspended by these window suspension chains to move up and down between the guide rails, and detachable at the bottom end of the window suspension chain A lowermost chain piece connected to the upper and lower sides of the lifting window, and the lowermost chain piece to the chain connecting plate from a link pin pitch of the window suspension chain. Also, chain connecting means for selectively connecting in the height direction of the chain connecting plate for every short pitch is provided.

  According to the present invention, the lowermost chain piece is detachably connected to the hanging lower end portion of the window suspension chain that is meshed with the sprocket of the window raising / lowering drive system and suspended in the guide rail, and the left and right sides of the upper portion of the raising / lowering window are Each of the chain connecting plates is attached, and the lowermost chain piece is selectively connected to the chain connecting plates in the height direction of the chain connecting plate at a pitch shorter than the link pin pitch of the window suspension chain. Since the chain connecting means is provided, when the shoulder window is lowered after installation, the window suspension chain is installed at the lifting window suspension base of either the left or right window suspension chain. Can be finely adjusted to a length shorter than the length of one frame, and this makes it possible to easily correct and adjust the shoulder drop even if the elevator window has a slight shoulder drop. It can be an effect that the correct levelness of the lifting windows can be easily ensured.

  As described above, when the shoulder window (inclination) occurs in the lifting window 3 that is suspended by the left and right window suspension chains 11 and installed on the site, the snap stopper 18 is attached to one side of the lifting window 3. The link pins 14a and 14b of the lowermost chain piece 15A are removed from the pin holes 17a and 17c of the chain connecting plate 17, and the lower link pin 14b of the lowermost chain piece 15A after the removal is shown in FIG. Further, by inserting and replacing the upper pin hole 17a or the intermediate pin hole 17b of the chain connecting plate 17, it is possible to prevent the lifting window 3 from being lowered and to suspend the lifting window 3 horizontally. Therefore, as described above, the lowermost chain piece 15A integrally having the upper and lower link pins 14a, 14b, the snap stopper 18 and the chain connecting plate 17 correct the inclination of the elevating window 3, and lower the shoulder of the elevating window 3. It constitutes a shoulder drop prevention means for preventing the above. As described above, the lifting window 3 suspended in the horizontal state by the window suspension chain 11 suspended in the left and right first guide rails 1 has the vertical rods 32 on both the left and right sides thereof. The vertical rods 32 are fitted in the vertical grooves 1 a so as to be movable up and down, and the vertical rods 32 are not exposed between the guide rails 1. Further, a sealing material 22 (see FIG. 3) such as mohair for sealing the space between the vertical gutters 32 is provided on the opposing wall portion of the vertical groove 1a.

  Further, inside both the guide rails 1, a chain bending restricting portion 21 (see FIG. 3) for restricting the bending of the window suspension chain 11 hanging from the sprocket 10 of the lifting window drive system is provided. The chain bending restricting portion 21 is configured to slidably sandwich the window suspension chain 11 suspended from the sprocket 10 over the entire length of the suspension to prevent the window suspension chain 11 from being bent. Explained. That is, the chain bend restricting portion 21 is formed of a pair of chain guides 21 a that are formed to project from the center portion of the inner surface of the back wall of the both guide rails 1 and are spaced apart from each other and extend in the longitudinal direction of the guide rail 1. The chain guides 21 a have bending restriction pieces 21 b that are bent in an L shape in the relative direction at the respective leading ends and intervene between the side link plates 12 of the window suspension chain 11. The front end surfaces of the bending restricting pieces 21b are set to be opposed to each other at a larger interval than the outer diameter of the chain roller 13 of the window suspension chain 11.

  Therefore, the chain bending restriction portion 21 is configured to allow the window suspension chain 11 to move up and down between the bending restriction piece portions 21b. In the chain bend restricting portion 21 as described above, the chain guide 21a having the bend restricting piece portion 21b at the tip as described above extends from the lower ends of the both guide rails 1 to a position near the sprocket 10, and the sprocket 10 The bending of the window suspension chain 11 is restricted by the bending restriction piece portion 21b over the entire length of the hanging portion of the window suspension chain 11 hanging from the guide rail 1 to the guide rail 1.

  In the above, the first guide rail 1 and the second guide rail 2 are detachably connected by fastening means such as bolts and nuts so as to be integrated as a unit, and the left and right guide rails 1 and 2 are integrated. Is integrated into a front gate shape by fixed windows 4 and 5, and a window driving device 7 is attached and set to the bracket 6 integrated at the upper end of the first guide rail 1, and meshes with the sprocket 10. One window unit U1 is configured by the lifting window 3 being suspended by the window suspension chain 11. This window unit U1 is manufactured at a factory, carried into an installation site, and installed. After the installation, if the lifting window 3 is inclined (shouldered), the snap stopper 18 of the lowermost chain piece 15A of the window suspension chain 11 on one side of the lifting window 3 is removed and the lowermost part is removed. The link pins 14a and 14b are removed from the chain connecting plate 17 together with the chain piece 15A. After the extraction, any one of the pin holes 17a, 17b, 17c of the chain connecting plate 17 that corresponds to a position where the lifting window 3 can be held in the horizontal position is selected, and the selected pin holes 17a, 17b, 17c At least the lower link pin 14b of the chain connecting plate 17 is replaced and inserted. Next, by inserting and engaging the snap stoppers 18 across the link pins 14a and 14b, the elevating window 3 can be held in a horizontal state without inclination.

Next, the operation will be described.
In the closed state in which the elevating window 3 is at the lower limit position between the left and right guide rails 1, when the sprocket 10 at both ends of the rotary shaft 9 is driven to rotate clockwise in FIG. When the window suspension chain 11 that has been suspended in the first guide rail 1 is pulled up, the elevating window 3 is lifted and opened along the first guide rail 1. At this time, the elevating window 3 is pulled up to the back side (inside the room) of the fixed windows 4 and 5, and is raised to a position where the eaves window of the elevating window 3 and at least the eaves of the lower fixed window 4 are the same or higher. Stop. When the sprocket 10 is driven to rotate counterclockwise in the open state of the lift window 3, the lift window 3 is lowered along the guide rail 1 and stops at the lower limit position.

  The elevating window 3 closed in this way is held in a locked state where there is no fear that it will be lifted even if it is unintentionally lifted and opened from the outside. That is, the opening / closing machine 8 has an interlock function, and the chain pressing member 16 is disposed above the meshing region of the window suspension chain 11 meshed with the sprocket 10, and is suspended in the guide rail 1. When the window suspension chain 11 in the state is sandwiched between the bending restriction piece portions 21b of the chain bending restriction portion 21 and held in a straight state, the window suspension chain 11 is lifted by the lifting force from the outside of the lifting window 3. The window suspension chain 11 is not bent or detached from the sprocket 10 upward. For this reason, the elevating window 3 is locked without requiring any special locking means.

  According to the first embodiment described above, the window suspension chain 11 that is engaged with the sprocket 10 of the window lifting drive system and suspended in the first guide rail 1 is sandwiched over the entire length of the suspension. 11 is provided in the guide rail 1 so as to prevent the bending of the sprocket 10, and the opening / closing device 8 that rotationally drives the sprocket 10 has an interlock function. Even if it is attempted to lift up and open from the outside, the window suspension chain 11 will not be bent or the sprocket 10 will not be rotated by the lifting force. Therefore, the lifting window 3 is locked in the fully closed position. Thus, there is an effect that the lock function of the elevating window 3 can be obtained without requiring special locking means, and the anti-theft property can be ensured. Further, since the chain pressing member 16 is arranged in the vicinity of the meshing region of the window suspension chain 11 in the sprocket 10, the window suspension chain 11 is moved to the sprocket 10 by lifting the lifting window 3 in the fully closed position. There is an effect that the anti-theft property can be further improved without being deviated from the above.

  Further, the chain bend restricting portion 21 is configured to interpose a bend restricting piece portion 21b bent in a relative direction at the distal ends of a pair of left and right chain guides 21a between both side link plates 12 of the window suspension chain 11. Therefore, there is an effect that the elevating window 3 can be always moved up and down smoothly without interference between the elevating window 3 and the chain bending restricting portion 21 during the elevating operation of the elevating window 3. Moreover, since the chain bending restricting portion 21 extends in the longitudinal direction within the first guide rail 1, a hollow columnar mold material is applied as the first guide rail 1 integrally having the chain bending restricting portion 21. Even in the second guide rail 2, a hollow columnar mold material can be applied, and the window unit U1 can be manufactured at the factory and carried into the installation site, thereby reducing the construction time at the installation site. There is an effect that it can be greatly shortened. Furthermore, when the window unit U1 is carried in, the window suspension chain 11 does not dance in the first guide rail 1 and the lifting window 3 does not swing, so that the window unit U1 can be carried in easily. There is an effect that can be.

  Furthermore, in the said Embodiment 1, although it was set as the combination structure of the raising / lowering window 3 and the fixed windows 4 and 5, the said raising / lowering window 3 is the 2nd guide rail 2 to which the said fixed windows 4 and 5 were attached and fixed. Since it is configured to move up and down along another first guide rail 1, the lifting window 3 can be moved up and down regardless of the fixed windows 4 and 5. That is, the sprocket 10 engaged with the window suspension chain 11 that suspends the elevating window 3 that elevates and lowers along the first guide rail 1 so as to pass the fixed windows 4 and 5 is connected to the first guide rail 1. So that the elevating window 3 can be lifted up to a position near the sprocket 10 regardless of the fixed windows 4, 5. Therefore, a so-called hoisting machine unit of the window drive device 7 system including the sprocket 10 is provided. Even if the height of the fixed windows 4 and 5 hanging from the ceiling under the ceiling (the dimension of the hanging from the ceiling) is shorter than the height of the lift window 3, the lift window 3 and the fixed window 4 are fixed. The elevating window 3 can be raised to a position where the eaves are the same. Therefore, the lifting / lowering stroke of the lifting / lowering window 3 is not restricted by the fixed windows 4 and 5, and the lifting / lowering stroke of the lifting / lowering window 3, particularly the opening area (window opening area) of the lifting / lowering window 3 can be freely set. There is an effect that can be done. Further, there is an effect that even if the size of the elevating window 3 and the fixed windows 4 and 5 are different, they can be accommodated so as to overlap each other.

  The elevating window 3 and the fixed window 4 may be arranged alternately at predetermined opening intervals in the vertical direction so that the elevating window 3 moves up and down like the fixed window 4. A plurality of window openings formed between a plurality of fixed windows 4 adjacent to each other at a predetermined interval in the direction are opened and closed simultaneously by a plurality of elevating windows 3 connected in series in the vertical direction via a window suspension chain 11. There is an effect that can be done. Therefore, there is an effect that the window opening area can be set freely.

  Furthermore, according to the first embodiment, the lowermost chain piece 15a of the window suspension chain 11 hanging in the first guide rail 1 can be attached and detached, and the chain connecting plates are provided on both upper sides of the elevating window 3. 17 is provided, and a plurality of pin holes 17a, 17b, 17c are provided in the longitudinal direction of the chain connecting plate 17, and the interval between the pin holes 17a, 17b, 17c is set so that the link pins 14 of the window suspension chain 11 and 14a, 14b is set to be shorter than the pitch between the pin holes 17a, 17b, 17c, and the link pins 14a, 14b of the lowermost chain piece 15A are inserted, and the link pins 14a, 14b are inserted. Since the snap stopper 18 is detachably fitted and engaged across the window, the inclination (shoulder) of the elevating window 3 after the installation of the window unit U1 in the field is carried out. In the case of occurrence of (burr), adjustment is made to correct the inclination of the elevating window 3 by replacing and inserting at least the lower link pin 14b of the link pin 14a, 14 into any of the pin holes 17a, 17b, 17c. There is an effect that it can be easily performed. Further, as described above, since the window suspension chain 11 suspended in the first guide rail 1 is sandwiched and held by the chain bending restricting portion 21, the internal space of the first guide rail 1 is maintained. The electrical wiring can be performed without any trouble.

In the second embodiment, the window unit U1 according to the first embodiment and another window unit U2 having the same configuration are arranged in the same row, and the positioning of the window units U1 and U2 at the time of the arrangement is easy. The configuration is such that it can be performed. That is, the window units U1 and U2 have the same configuration as described above, and positioning protrusions are provided on the rear side of the outer wall of the guide rails 1 and 2 (the second guide rail 2 is omitted in FIG. 7). Since the portions 1b and 2b (see FIG. 3 for the protrusion 2b) are integrally formed in the vertical direction, the protrusions 1b and 2b of the guide rails 1 and 2 of the window unit U1 and the guide rails 1 and 2 of the window unit U2 In this state, the projections 1b and 2b on the side of the window unit U2 and the projections 1b and 2b on the side of the window unit U2 adjacent thereto are brought into contact with each other. By fastening with the set screw 23, the guide rails 1 and 2 of the window unit U1 and the guide rails 1 and 2 of the window unit U2 are assembled and assembled in the same row.

  In the assembled state of the window units U1 and U2 adjacent to each other, a gap corresponding to the protruding length of the protruding portion 1b is generated between the first guide rails 1 adjacent to each other. The cover member 24 is fitted into the gap. The cover member 24 is formed in a substantially U-shaped cross section by an elastic resin, and an engaging claw 24b is integrally formed on the outer side surface of the both side piece portions 24a. The engaging claws 24b are elastically engaged with the opposing back wall surfaces of the guide rails 1 by press-fitting both side pieces 24a of the cover member 24 into the gap between the guide rails 1 adjacent to each other. In this state, the back wall surface of the cover member 24 and the outer wall surface of each guide rail 1 are flush with each other.

  According to the second embodiment described above, the guide rails 1 and 2 of one window unit U1 and the guide rails 1 and 2 of the other window unit U2 are adjacent to each other when the plurality of window units U1 and U2 are connected. It is easy to accurately position the one guide rails 1 and 2 and the other guide rails 1 and 2 simply by butting the projections (positioning portions) 1b of the respective guide rails in a staggered manner. This can be done neatly, and has the effect of greatly shortening the time for continuous installation between the window units U1, U2. Further, since the window driving device (winding machine unit) 7 is accommodated within the outer dimension interval width between the left and right guide rails 1 for each of the window units U1 and U2, each time the window units U1 and U2 are connected to each other, The hoisting machine units 7 of the window units U1 and U2 do not interfere with each other, and there is an effect that a large number of window units U1 and U2 can be easily connected. Furthermore, since the gap between the guide rails 1 adjacent to each other is closed by the cover member 24 when the window units U1 and U2 are installed in series, the head of the set screw 23 may be exposed outside the window unit. In addition, since the cover member 24 and the outer wall surface of the guide rail 1 are flush with each other, there is an effect that the appearance of the multiple window unit is not impaired. Further, the cover member 24 has an effect that the engagement claw 24b can be engaged and held on the wall surface of the guide rail 1 only by the elastic force of the side pieces 24a.

The chain tray 25 receives and stores a surplus hanging portion of the window suspension chain 11 that hangs down from the sprocket 10 when the elevating window 3 is pulled up, and is configured to restrict the bending of the window suspension chain 11 during the storage. ing. As the bending restricting means, the length of the left and right of the chain tray 25 is minimized so that the window suspension chain 11 accommodated in the chain tray 25 is not entangled twice. The width of the chain 11 is set to be not less than 1 and not more than 2 times the chain width, and can be stored while restricting the bending of the window suspension chain 11. The chain tray 25 may be configured to have elasticity capable of buffering the window suspension chain 11 accommodated therein.

  According to the sixth embodiment described above, the chain tray 25 for receiving and storing the surplus hanging portion of the window suspension chain 11 that hangs down from the sprocket 10 when the elevating window 3 is pulled up is disposed. Since the chain tray 25 is configured so that the bending of the window suspension chain 11 is restricted when the window suspension chain 11 is stored, the window suspension chain 11 is extended from the sprocket 10 when the lifting window 3 is pulled up. There is an effect that it does not hang down and protrude from the hoisting machine unit (unitized portion of the entire window driving device 7). Moreover, since the length of the left and right sides is minimized by setting the chain tray 25 to a width dimension of 1 to 2 times the chain width of the window suspension chain 11, There is an effect that the window suspension chain 11 housed in the window drive chain 11 is not entangled and the entire width (left-right width) of the window drive device 7 can be made compact. Further, by forming the chain tray 25 with an elastic material or having an elastic tank on the inner surface, the window suspension chain 11 suspended and stored in the chain tray 25 is buffered and the window suspension chain 11 is buffered. There is also a silencing effect that can absorb the collision sound.
