Description

  The present invention relates to a sliding door device called a barrier-free sash, in which a sliding door device is built in a window frame having a flat upper surface of a lower frame, and an improvement of a guide member incorporated in the sliding door device.

  In order to ensure the ease of movement of the elderly and the physically handicapped, the structure of a window frame that is called a barrier-free sash, with the upper surface of the lower frame flattened, is described in, for example, Patent Documents 1 to 4, etc. Various types have been conventionally known. In each of the structures described in these patent documents, the outer peripheral surface of the door wheel installed on the lower arm of the sliding door is a simple cylindrical surface, and the outer surface of the door wheel is in contact with the upper surface of the lower frame. It is a surface.

  In the case of such a conventional structure, since a special thing different from what was conventionally used as a doorwheel is used, unless it spreads widely in the future, there is a possibility that the cost will increase. In particular, at present, when repairing or replacing a broken trolley, the labor and cost required for obtaining the trolley may be higher than that of a general one where concave grooves are formed on the entire circumference. There is. Further, since the engaging portion between the door pulley and the lower frame cannot position the sliding door shoji in the indoor / outdoor direction, a structure for separately positioning the sliding door shoji in the indoor / outdoor direction is necessary.

  In consideration of such circumstances, a lower frame with a lower guide rail is used as the lower frame, and the upper edge of the lower guide rail is the part of the upper surface of the lower frame where people and objects move It is advantageous to adopt a structure that is positioned below the lower part. In this case, a recess is provided on the upper surface of the lower frame in the moving direction of the sliding door shoji, and the lower guide rail is provided so as to protrude upward from the bottom surface of the recess. Accordingly, there is an opening of the recess on the upper surface of the lower frame, and the upper edge of the lower guide rail is present at the center of the opening.

  The concave portion and the lower guide rail are provided over the entire length of the lower frame, whereas the length (width) of the sliding door shoji is shorter than the total length of the lower frame. For this reason, the opening part of the said recessed part and a part of length direction of the upper end edge of a lower guide rail are exposed without being covered with the said sliding door shoji. For this reason, not only the appearance of the said part worsens, but when a foreign material falls in the said recessed part, it becomes difficult to take out this foreign material. That is, since the upper end edge of the lower guide rail exists at an approximately middle portion of the opening of the recess, the opening is divided into two in the width direction and becomes narrow. As a result, when a foreign substance such as a pin falls into the recess, it is difficult to take out the foreign substance.

  In Patent Document 5, when a shutter panel is wound up by a part of a lift guide groove for guiding both side edges of a lift-type shutter, a portion exposed below the shutter panel is covered with a band-shaped sealing material. The structure is described. However, such a structure described in Patent Document 5 is intended only to cover the opening of the groove existing in the vertical direction, and covers the upper end opening of the groove existing on the upper surface of the lower frame of the sliding door device. It is not intended to be a thing. Moreover, it is difficult to apply to a sliding door apparatus having a complicated structure such as winding a strip-shaped sealing material by a winding mechanism and having a limited installation space.

Japanese Utility Model Publication No.55-19814 JP 2000-96934 A Japanese Patent No. 3233920 Japanese Patent No. 3233921 JP-A-5-340173

In view of the circumstances as described above, the present invention uses a lower frame having a lower guide rail on the upper surface, and the upper edge of the lower guide rail is placed on the upper surface of the lower frame. The invention was invented to realize a structure that is positioned below the moving part, that makes the upper surface of the lower frame look good and that foreign matter can be prevented from falling into the recesses.
At the same time, the present invention makes it possible to realize a structure in which the indoor and outdoor airtightness can be satisfactorily maintained and the operation of attaching and removing the sliding door shoji to the window frame can be easily performed.

  Of the guide member with a sealing lip for a sliding door device and the sliding door device of the present invention, the guide member with a sealing lip for a sliding door device according to claim 1 is an upper end opening of a recess provided on an upper surface of a lower frame constituting the sliding door device. A guide groove for guiding the side edge of the band-shaped cover band covering the part, and a seal that contacts the side surface of the hanging wall part provided at the lower end part of the lower arm that constitutes the sliding door shoji that moves on the upper surface of the lower frame A lip is integrally provided. And it is used in the state latched by the said lower frame by the upper inner surface of the said recessed part.

  In addition, the sliding door device according to claim 2 supports a plurality of door wheels on a lower arm that constitutes the lower side so as to be rotatable around the horizontal axis, as in a sliding door device that has been generally implemented conventionally. A window including a sliding frame and a lower frame formed on its upper surface with a lower guide rail that guides the horizontal movement of the sliding door by engaging a groove formed on the outer circumferential surface of each door. And a frame.

In particular, in the sliding door device of the present invention, the lower guide rail is provided on the upper surface of the lower frame so as to protrude upward from the bottom surface of the recess existing in the moving direction of the sliding door shoji. The upper end edge does not protrude above the portion of the upper surface of the lower frame that exists on both sides of the recess.
Further, by moving a cover band provided between the lower end portion of the ridge constituting the vertical side of the sliding door shoji and the end portion of the window frame, the upper end opening of the concave portion is moved along with the movement of the sliding door shoji. It is comprised so that the part which is not covered with the said sliding door shoji may be covered by a part.
The cover band is made of an elastic material, such as a thin stainless steel plate, having flexibility and a rigidity that can be moved by pressing force. One end of the cover band is coupled to the lower end of the collar, and an intermediate portion is provided inside a guide member fixed to a continuous portion of a lower frame and a vertical frame coupled at right angles to each other. The movement direction is changed 90 degrees from the horizontal direction to the vertical direction by being guided by the guide path. In addition, a part of the cover belt that moves in the vertical direction exists in the vertical frame.
Further, a pair of guide members each having a guide groove for guiding the cover band by engaging the both end edges of the cover band with a portion near the upper end opening of the pair of inner side surfaces that partition the recess. It is provided in a state of being locked to a portion near the upper end opening of the pair of inner side surfaces.
Further, a seal lip is provided integrally with the guide member at a portion of at least one of the guide members that is present below the guide groove. And the front-end | tip of this seal lip is slidably contacted with the side surface of the drooping wall part which was provided in the lower end part of the said lower collar and entered in the said recessed part.

In the case of the sliding door device of the present invention configured as described above, the lower frame is provided with a lower guide rail on the upper surface. What formed the ditch | groove can be used. For this reason, besides the cost of the door cart itself can be kept low, the sliding door shoji can be positioned in the indoor and outdoor directions at the engaging portion between the door wheel and the lower guide rail. Therefore, it is not necessary to provide a separate structure for positioning the sliding door screen in the indoor / outdoor direction, and the cost can be reduced from this aspect.
In addition, since the upper edge of the lower guide rail is positioned below the portion of the upper surface of the lower frame where people and objects move, the upper surface of the lower frame is made substantially flat so that the person And move objects easily.
In order to prevent the upper end edge of the lower guide rail from protruding upward, the upper end opening of the recess provided on the upper surface of the lower frame covers the portion not covered by the sliding door shoji with a cover band. The appearance of the upper surface of the lower frame can be improved, and foreign matter can be prevented from falling into the recesses.
In addition, since a guide member having a guide groove is provided, the force required to move the cover band is reduced while preventing the cover band from being lifted, and the sliding door sliding element coupled with one end of the cover band is moved. Can be reduced.
Furthermore, since the seal lip is integrally provided on the guide member, the gap between the lower frame constituting the sliding door shoji and the lower frame constituting the window frame can be closed, and the indoor and outdoor airtightness can be favorably maintained. . Moreover, since the distance between the guide groove and the seal lip can be shortened with respect to the depth direction of the recess, even if the amount of the penetrating wall portion entering the recess is reduced, the leading edge of the seal lip is placed on the drooping wall portion. It is surely brought into contact with the side surface of the By holding the sliding door in a small amount, the bottom edge of the hanging wall comes out from the top opening of the recess, and the sliding door is removed from the window frame. It is possible to realize a structure that can easily perform the work to be performed.

When the present invention is implemented, for example, as described in claim 3, a guide member provided with a seal lip is used as an indoor guide member. Then, the front end edge of the seal lip is brought into sliding contact with the indoor side surface of the hanging wall portion that has entered the recess at a portion closer to the indoor side than the lower guide rail. On the other hand, no seal lip is provided on the outdoor guide member.
If such a configuration is adopted, when wind is blown to the sliding door shoji and the sliding door shoji is pushed indoors, the leading edge of the seal lip and the hanging wall portion are surely brought into contact with each other. The airtightness between the lower arm and the lower frame can be improved. Since the contact surface pressure between the tip edge of the seal lip and the hanging wall can be kept low, including the case of opening and closing the sliding door shoji, the force required to open and close the sliding door shoji can be kept low. .

Preferably, as described in claim 4, the guide member is made by combining a plurality of types of polymer materials. Of these, the polymer material constituting the portion of the inner surface of the guide groove and the seal lip that is in sliding contact with the hanging wall portion is a polymer material having a low friction coefficient. Moreover, the part which latches the said guide member with respect to a lower frame is made into the polymeric material which has elasticity.
With this configuration, the sliding contact portion between the edge of the cover band and the guide groove and the sliding contact between the seal lip and the hanging wall portion can be performed without troublesome work for assembling the guide member to the lower frame. The frictional resistance of the part can be kept low, and the force required to move the sliding door shoji can be reduced.

The frictional resistance is reduced with respect to the movement of each of the cover bands 24a to 24d in 37a to 37d.

  In the case of this embodiment, the horizontal ends of the guide grooves 25a and 25b formed in the guide members 26a and 26b, and the horizontal portion side openings of the guide passages of the guide brackets 36a and 36b, respectively. And the guide grooves 25a, 25b and the guide passage are made continuous. With this configuration, the cover bands 24a to 24d can be transferred between the guide grooves 25a and 25b and the guide passage.

  In the case of the present embodiment configured as described above, if each of the glass shojis 2a and 2b is moved, the summing rods 8a and 8b and the butting rods 9a and 9b of the glass shojis 2a and 2b and the respective rod frames 5a. The cover bands 24a to 24d are transferred to and from 5b. The portions of the recesses 15a and 15b that are not covered with the lower collars 7a and 7b of the glass shojis 2a and 2b are covered with the cover bands 24a to 24d. That is, when the respective saddles 8a, 8b, 9a, 9b move away from the opposing saddle frames 5a, 5b as the glass shojis 2a, 2b move, the lower ends of the saddles 8a, 8b, 9a, 9b The cover bands 24a to 24d coupled to the portions are pulled out from the storage portions 37a to 37d of the collar frames 5a and 5b while the direction is changed by 90 degrees in the guide passage portions provided in the guide brackets 36a and 36b. It is. The cover bands 24a to 24d are bridged between the lower ends of the flanges 8a, 8b, 9a and 9b and the lower ends of the flange frames 5a and 5b. The upper end openings of 15a and 15b cover the exposed portions between the lower ends of the flanges 8a, 8b, 9a and 9b and the lower ends of the flange frames 5a and 5b. In this state, in the upper surface of the lower frame 4, the appearance between the lower end of each of the flanges 8a, 8b, 9a, 9b and the lower end of each of the flange frames 5a, 5b is improved, and It is possible to prevent foreign matter from falling into the recesses 15a and 15b at the portion between them.

  In the case of the present embodiment, both side edges of the cover bands 24a to 24d, which are pulled out from the storage portions 37a to 37d and cover a part of the recesses 15a and 15b, are the guide grooves. It will be in the state latched by 25a, 25b. For this reason, it can prevent reliably that the both-ends edge of each of these cover belt | bands 24a-24d floats from the opening edge part of said each recessed part 15a, 15b. As a result, it is possible to effectively prevent fine foreign matter from getting into the recesses 15a and 15b and catching something on the cover bands 24a to 24d.

  On the other hand, when each of the scissors 8a, 8b, 9a, 9b approaches the facing scissors frames 5a, 5b as the glass shojis 2a, 2b move, the lower ends of the scissors 8a, 8b, 9a, 9b The cover strips 24a to 24d coupled to the guide frames are pushed into the storage portions 37a to 37d of the flange frames 5a and 5b while the direction is changed by 90 degrees in the guide passage portions provided in the guide brackets 36a and 36b. It is. Each of the cover strips 24a to 24d has a property such as a metal tape measure and has a certain degree of rigidity in the pressing direction. Therefore, as the glass shojis 2a and 2b move, the storage portions 37a to 37d. It is securely pushed into 37d.

  The portions that come into sliding contact with the movement of the glass shojis 2a and 2b, that is, the contact portion between the outdoor side surface of the seal lip 27 and the indoor side surface of the hanging wall portions 23a and 23b, and the inner surfaces of the guide grooves 25a and 25b And the contact portions of the cover bands 24a to 24d with both side edges, and the contact portions of the cover bands 24a to 24d and the liner members 40 and 40 are either one of the two surfaces in sliding contact with each other. Is covered with a slippery material. For this reason, the force required to move the glass shojis 2a and 2b is light.

  Furthermore, in the case of the present embodiment, since the seal lip 27 is provided integrally with the guide member 26a provided at the indoor side opening of each of the recesses 15a and 15b, the glass shoji 2a and 2b are provided. The gap between the lower gutters 7a and 7b constituting the window and the lower frame 4 constituting the window frame 1 can be closed, so that the airtightness indoors and outdoors can be favorably maintained. In addition, the distance between the guide groove 25a and the seal lip 27 can be shortened in the depth direction of the recesses 15a and 15b. For this reason, even if the amount of entry h of each of the hanging wall portions 23a, 23b into the respective recessed portions 15a, 15b is reduced, the leading edge of the seal lip 27 is placed on the indoor side surface of each of the hanging wall portions 23a, 23b. It is made to contact reliably. Then, by suppressing the amount of entry h to a small extent, the glass shojis 2a and 2b are slightly raised so that the lower end edges of the hanging wall portions 23a and 23b are located above the upper end openings of the concave portions 15a and 15b. Thus, it is possible to realize a structure capable of easily performing the work of attaching and detaching the glass shojis 2a and 2b to the window frame 1.

  That is, as is well known, when a sliding door such as the glass shoji 2a and 2b is built in a window frame, the sliding door shoji is lifted in an inclined state while the upper arm of the sliding door shoji and the window frame. Engage with the upper frame. Next, while moving the sliding door shoji in the vertical direction, the lower arm of the sliding door shoji is moved onto the lower frame of the window frame, and then the sliding door is lowered to engage the lower arm and the lower frame. . The procedure for removing the sliding door shoji from the window frame is performed in the reverse order of the case of such installation. When such a quick and easy attachment / detachment method is applied to the structure of the present embodiment, the lower edge of each of the hanging wall portions 23a, 23b is moved upward from the upper end opening of each of the recesses 15a, 15b in the attachment / detachment process. Need to be extracted. With the glass shoji 2a and 2b being built in the window frame 1, when the amount of the hanging wall portions 23a and 23b entering the recessed portions 15a and 15b increases, the hanging wall portions 23a and 23b It becomes difficult to extract the lower end edge of 23b upward from the upper end opening of each said recessed part 15a, 15b.

  For example, as shown in FIG. 11, when the guide member 26c for guiding the indoor side edges of the cover strips 24a and 24d and the seal lip 27a are separated, the structure of the present embodiment shown in FIGS. In comparison, the position of the seal lip 27a is positioned further downward with respect to the upper surface of the lower frame 4. Therefore, in order to make sure that the seal lip 27a and the indoor side surfaces of the hanging wall portions 23a and 23b are in contact with each other, the positions of the lower edges of the hanging wall portions 23a and 23b are shown in FIGS. It is necessary to position it below the case of the embodiment. For this reason, in the example shown in FIG. 11, the amount of entry H of each of the hanging wall portions 23 a, 23 b into the recesses 15 a, 15 b becomes large, and the glass shoji 2 a, 2 b can be attached to and detached from the window frame 1. The degree of freedom of design for making it is lost. Moreover, even if it can be made detachable, the height at which each of the glass shojis 2a and 2b has to be lifted at the time of attachment / detachment becomes large, and the attachment / detachment work becomes troublesome for a weak worker. In the case of this embodiment, such a trouble is eliminated by providing the seal lip 27 integrally with the guide member 26a.
