Description

  The present invention relates to a rail fastener for attaching a sliding door rail in which a rolling groove of a door wheel is formed along the longitudinal direction of the central portion to an entrance formed on the end face of a vinyl house, and a sliding door attachment using the fastener Concerning structure.

  Conventionally, a sliding door type door is often provided at an entrance formed on the end face of a vinyl house. This hanging door sliding door mounting structure has an upper rail of a predetermined length along the upper edge of the doorway and is disposed on the end face of the vinyl house, and a door wheel attached to the upper end of the sliding door. It is configured to slide in a suspended state. In such a sliding door type sliding door, generally, a lower rail that guides the lower portion of the sliding door is provided in order to obtain a stable sliding operation.

  The upper rail and the lower rail are attached to a pipe disposed on the face of the vinyl house via a rail fastener, and as such a rail fastener, for example, as shown in FIG. there were. In the drawing, X is an upper rail, 200 is a pipe-shaped end pillar, and the rail fastener 100 is substantially L-shaped in cross-sectional view with a width approximately the same as that of the upper rail X and a length of about 70 to 100 mm. The U-bolt 300 is fixed to the end post 200 with the upper rail X being formed. Reference numeral 400 denotes a thumbscrew.

  The rail fastener 100 is formed in a substantially L shape in sectional view from the flat surface portion 110 and the side surface portion 120, and supports the lower end portion of the upper rail X by bending the front end portion 121 of the side surface portion 120 inward. On the other hand, a bolt insertion hole is formed in the vicinity of the upper portion of the side surface 120, the U bolt 300 is inserted so as to straddle the end post 200, and the upper rail X is firmly secured to the end post 200 by the thumbscrew 400. It is to be screwed.

  In addition, as an example of a conventional rail fastener used in the sliding door mounting structure, there is a cross-sectional channel-shaped rail fastener in which the side surface portion 120 is extended downward from the front and rear end portions of the flat portion 110 (for example, (See FIG. 4 of Patent Document 1).

Also in such a rail fastener, the upper rail X can be fixed to the inner side surface of the pillar of the vinyl house by inserting a U-bolt through an insertion hole formed in the upper part of the side surface portion and tightening with a thumbscrew.
JP-A-8-116799

  However, since the conventional rail fastener 100 described above has only one or two plate-shaped side portions 120 to be tightened by the U bolt 300, the U bolt 300 and the butterfly screw 400 are used for the end post 200. The following problems may occur during installation.

  That is, the side-supporting side portion 120 is easily bent, so that the thumbscrew 400 can be easily screwed in. On the other hand, it is difficult to adjust the force for fastening. As shown in FIG. 15 (b), the front end 121 of the side surface 120 is warped in a direction away from the upper rail X, and the upper rail X may fall off the rail fastener 100.

  Thus, in the conventional rail fastener 100, it is difficult to adjust the fastening force by the U-bolt 300 and the wing screw 400, and useless nerves are used for construction, so that improvement is desired.

  In recent years, the number of cases in which a doorway of a vinyl house has a double sliding door structure and a screen door as an inner sliding door is increasing.

  However, in such a sliding door mounting structure, when the above-described conventional rail fastener is used, the upper rail cannot be easily arranged in parallel, and it is not easy to add a screen door to the existing sliding door structure. It was.

  That is, when adding a screen door, it was necessary to remove the existing upper rail and add a new upper rail using a dedicated connector. Therefore, it takes construction time and the construction cost increases.

An object of this invention is to provide the sliding door attachment structure using the rail fastener which can solve the said subject.

In the first aspect of the present invention, two sliding door rails each having a rolling groove for the door wheel formed along the longitudinal direction of the central portion are arranged in parallel with the doorway formed on the end face of the vinyl house via the rail fastener. It is a sliding door mounting structure in which an inner door and an outer door provided with a door are slidably supported so as to be slidably opened and closed, and the rail fastener is inserted through a fastener such as a U-bolt. A box-shaped base portion having opposing mounting surface portions each provided with a hole, a rail contact surface portion facing the rail base surface facing the rolling groove, and extending from one of the mounting surface portions of the box-shaped base portion And a rail support portion that folds the tip end portion inward and holds the sliding door rail from one side between the rail contact surface portion and the rail support pair as the rail support portion. Attached between the mounting surfaces on the opposite side Align, was sliding door mounting structure coupled by said fastener while embracing the sliding door rail of the duplicate between the rail support part opposed.

Further, in the present invention according to claim 2 , in the sliding door mounting structure according to claim 1 , an intermediate member formed in a gradually tapered shape from the base portion to the tip end portion is interposed in the abutting portion of the pair of rail fasteners. It is characterized by.

(1) In the present invention according to claim 1, two rail fasteners are used, the mounting surface portions opposite to the rail support portions are attached to each other, and the double sliding doors are provided between the rail support portions facing each other. Because it is connected with the tightening tool while holding the rail for rail, there is no need for a dedicated bracket for dual rails, etc., and a double sliding door mounting structure can be realized easily using the same rail fastener it can. In addition, it is possible to arrange a new rail along the existing rail while keeping the existing rail as it is, and to realize a double sliding door mounting structure at a low cost.

(2) In the present invention according to claim 2, when an intermediate member formed gradually tapered from the base portion to the tip portion is interposed at the abutting portion of the pair of rail fasteners, The lower ends of the two rails are strongly pressed along the shape of the member, and the rails are not separated from each other but are subjected to a force in the close contact direction, thereby preventing the possibility of falling off.

  The present invention relates to a rail fastener for attaching a sliding door rail formed with a rolling groove of a door pulley along a longitudinal direction of a central portion to an entrance formed on the end face of a vinyl house, and a fastening tool such as a U bolt A box-shaped base portion having opposing mounting surface portions each provided with an insertion hole for inserting a through-hole, a rail contact surface portion facing the rail base surface facing the rolling groove, and the mounting surface portion of the box-shaped base portion. In addition to extending from one side, the front end portion is bent inward, and the rail contact surface portion is provided with a rail support portion that holds the sliding door rail from one side.

  That is, it is a rail fastener used in the sliding door mounting structure provided at the doorway formed on the end face of the vinyl house, and by having the above configuration, the portion tightened by the fastener has a box shape and has sufficient strength Therefore, the rail support portion is not affected even if the tightening tool is tightened so that it functions sufficiently. Therefore, it is possible to easily realize a safe sliding door mounting structure that allows the fasteners to function sufficiently and does not cause the rails to fall off.

  As the rail fastener, an aluminum material can be suitably used, but an iron material or a resin material may be used. In addition, the longitudinal dimension may be adjusted to the size of the post that is the attached member, and is usually 70 to 100 mm, and more preferably 80 to 90 mm. Moreover, it is preferable that the width dimension is the same as the rail width dimension to be attached or about 0.5 mm shorter. At least, it should be avoided that it is wider than the rail width.

  In addition, although it can select suitably according to a pipe-shaped wife pillar as a fastening tool, the U bolt which can be fastened easily with a thumbscrew can be used suitably. Of course, a linear or belt-like fastener may be employed.

  If the rail fastener of the said structure is used, a novel sliding door attachment structure can be implement | achieved. In other words, two sliding door rails each formed with a rolling groove of the door wheel along the longitudinal direction of the central portion are arranged in parallel with the doorway formed on the end face of the vinyl house via a rail fastener, A sliding door mounting structure in which an inner door and an outer door provided with a door wheel are slidably supported so as to be slidable, and the rail fastener is provided with an insertion hole through which a fastener such as a U-bolt is inserted.

Garnish and oppose In which in a state between serial rail support unit and embracing the sliding door rail of the bipartite form a structure linked by the fastener.

  In this way, using two rail fasteners having the above-described configuration, the attachment surface portions opposite to the rail support portions are attached to each other, and the two sliding door rails are wrapped between the opposing rail support portions. By connecting with the tightening tool in the held state, a dedicated bracket for double rails or the like becomes unnecessary, and a double sliding door mounting structure can be easily realized using the same rail fastener. In addition, it is possible to arrange a new rail along the existing rail while keeping the existing rail as it is, and to realize a double sliding door mounting structure at a low cost.

  Therefore, for example, in an existing vinyl house, it is possible to implement a new sliding door type screen door at a low cost while keeping the existing sliding door as it is.

  In the sliding door mounting structure described above, it is preferable that an intermediate member that is gradually tapered from the base portion to the distal end portion is interposed at the abutting portion of the pair of rail fasteners.

  With this configuration, when a fastening tool such as a U-bolt is tightened with a thumbscrew, the lower ends of the two rails are strongly pressed along the shape of the intermediate member, and the rails are not separated but are in close contact with each other. A force is applied in the direction, and the risk of the two rails falling off can be prevented.

  Hereinafter, embodiments of the present invention will be described more specifically with reference to the drawings. FIG. 1 is an explanatory view of a vinyl house provided with a sliding door mounting structure according to the present embodiment, FIG. 2 is an explanatory view of a sliding door mounting structure provided at an entrance provided on the end face of the vinyl house, and FIG. 3 is a front view of a rail fastener. 4 and FIG. 4 are a side view and a front view showing a state where the upper rail is attached by the rail fastener, FIG. 5 is a perspective view thereof, and FIG. 6 is an explanatory view showing a method of attaching the rail fastener. 7 is explanatory drawing by the cross sectional view of the whole sliding door mounting structure which concerns on this embodiment.

  A vinyl house 1 shown in FIG. 1 is formed by connecting a plurality of pipes 10 for building a house with predetermined fasteners at appropriate positions, and covering a vinyl sheet S on the outside of a structure constructed by combining these pipes 10. Configured. Reference numeral 13 denotes a post, which is a rectangular cylinder in this embodiment, but may be a cylindrical pipe.

  An entrance / exit 2 is formed on the end face 11 of the vinyl house 1, and a sliding door mounting structure having the rail fastener 6 according to the present embodiment is applied to the entrance / exit 2.

  The entrance 2 is a relatively large opening through which a farm machine such as a tractor or a vehicle such as a truck can pass, and has a length corresponding to the opening size formed between the pillars 13 and 13 at the upper and lower positions of the entrance 2. The upper rail 4 and the lower rail 5 having substantially the same structure are arranged, and the two sliding door type sliding doors 3 and 3 are slidably mounted in the upper and lower rails 4 and 5.

  The upper and lower rails 4 and 5 are fixedly attached to the end post 13 by upper and lower rail fasteners 6 and 6 ', respectively. The sliding door 3 slidably mounted between the upper and lower rails 4 and 5 is formed in a rectangular shape by combining the vertical frame 31 and the horizontal frame 32. As shown in the drawing, two sliding doors 3 are provided on the upper edge. No. 3 and 33 are connected to each other.

  The upper rail 4 disposed along the upper edge of the doorway 2 is made of metal having a desired strength, and is formed in a channel shape from a rail base surface 40, left and right side surfaces 41, 41, and a lower surface 42 forming an upper surface. A rolling groove 43 is formed in a slit shape on the lower surface 42 so that the door wheel 33 is slidable and does not fall off (FIGS. 4 to 7). As shown in FIG. The sliding door 3 is suspended by engaging the door wheel 33 with the groove 43 so as to roll freely.

  On the other hand, as shown in FIG. 7, the lower rail 5 disposed at the lower part of the entrance / exit 2 has substantially the same length as the upper rail 4, and the lower rail 5 can guide the lower end of each sliding door 3. It is said. That is, the lower rail 5 is also made of metal having a desired strength, and is formed in a channel shape from the rail base surface 50, the left and right side surfaces 51, 51, and the upper surface 52 that form the installation surface. A sliding groove 53 is formed to guide the slide to the left and right while preventing the rattling in the front-rear direction by passing through the lower end of 3. In FIG. 7, G <b> 1 is a recess excavated on the ground surface G according to the thickness of the lower rail fastener 6 ′ in order to place the lower rail 5. There are no more gaps between them.

  Here, the upper and lower rail fasteners 6, 6 'for attaching the upper rail 4 and the lower rail 5 to the end post 13 will be described in detail.

  As shown in FIGS. 3 and 4, the upper rail fastener 6 includes a mounting surface portion 62 provided with a plurality of insertion holes 61 through which the U-bolts 7, which are tightening tools, are respectively provided, and a rotating surface of the upper rail 4. The box-shaped base 60 having a flat rail contact surface 63 opposed to the rail base 40 facing the moving groove 41, and extending from one of the mounting surface 62 of the box-shaped base 60, and the tip 64a It comprises a rail support portion 64 that is bent inward and holds the upper rail 4 from one side between the rail contact surface portion 63. In addition, the width of the rail contact surface portion 63 is set to be about 0.5 mm smaller than the width of the upper rail 4. The reason why the plurality of insertion holes 61 are provided is to allow a plurality of types of U-bolts 7 corresponding to the pillars 13 having different sizes and shapes to be inserted, as shown in FIG.

  By the way, although the upper rail fastener 6 and the lower rail fastener 6 ′ in the present embodiment have basically the same structure, the upper surface portion 65 of the upper rail fastener 6 is inclined downward toward the rail support portion 64. However, since the lower rail fastener 6 'may be grounded, the lower surface portion 65' has a flat surface. The upper surface portion 65 of the upper rail fastener 6 does not necessarily need to be inclined, and may be formed on a flat surface like the lower surface portion 65 'of the lower rail fastener 6'. By the way, in the following description, for the sake of convenience, it may be expressed as a rail fastener 6, which means that the upper rail fastener 6 and the lower rail fastener 6 ′ are indicated at the same time.

  As described above, the rail fastener 6 according to the present embodiment uses the box-shaped base portion 60 as the portion through which the U bolt 7 is inserted, so that it is extremely strong in strength. As shown in FIGS. 13, even when the U bolt 7 inserted through the insertion holes 61, 61 is tightened with the thumbscrew 70, the rail support portion 64 is not affected. Therefore, there is no possibility that the upper rail 4 falls off the upper rail fastener 6.

  Here, the case where the upper rail 4 is actually attached using the upper rail fastener 6 will be briefly described.

  As shown in FIG. 6, the upper rail 4 is held by the rail support portion 64 and the rail abutment surface portion 63 in a state in which the tip end portion 64 a of the rail support portion 64 of the upper rail fastener 6 is locked to the upper rail 4. In this state, the U-bolt 7 is inserted into the insertion hole 61 provided in the box-shaped base 60 of the upper rail fastener 6 from the rear of the end post 13, and the upper rail fastener 6 is firmly secured using the thumbscrews 70, 70. It is fixed to the wife pillar 13. At this time, the box-shaped base 60 composed of the mounting surface portions 62 and 62, the upper surface portion 65, and the rail contact surface portion 63 through which the U-bolt 7 is inserted has extremely high rigidity, so that regardless of the tightening amount of the thumbscrew 70. The rail support portion 64 does not warp, the upper rail 4 is securely held, and even when the sliding door 3 is attached to the upper rail 4, the state of holding firmly is maintained, and the rail falls off. Does not occur.

  Next, a sliding door mounting structure in which the sliding doors 3 are arranged in two inside and outside will be described. This is a structure in which demand is increasing in recent years, and is required when a screen door is provided at the entrance 2 of the vinyl house 1. In this case, in general, a normal sliding door 3 is disposed on the outside, and a sliding door 3 having a screen door specification is disposed on the inside. Such a double sliding door mounting structure can be provided by using the rail fastener 6 described above. It can be easily constructed without using fasteners.

  8 is an explanatory view showing an upper rail portion of a novel double sliding door mounting structure using a pair of rail fasteners 6, FIG. 9 is an explanatory view showing the lower rail portion, and FIGS. 10 and 11 are existing rails. FIG. 12 is an explanatory view showing an upper rail mounting method for forming the new double sliding door mounting structure, and FIG. 13 is an explanatory view of the intermediate member, and FIG. 14 is an explanatory view in a sectional view of the entire sliding door mounting structure in which one rail is newly added to the existing rail.

  For example, when a double sliding door mounting structure is constructed at the doorway 2 when the vinyl house 1 is newly installed, as shown in FIGS. 8 and 9, the rail fastener 6 having the above-described structure is attached to the upper rail 4. Two lower rails 5 may be used, i.e., a pair, and the attachment surfaces 62 that are opposite to the rail support portions 64 of the respective rail fasteners 6 are attached to each other between the two rail support portions 64 facing each other. The two upper rails 4 and 4 or the lower rails 5 and 5 are held side by side and connected by a U-bolt 7 having a length for the double rails.

  That is, the case where the upper rails 4 and 4 are attached will be described with reference to FIG. 12. As shown in the figure, the upper rail fastener 6 is in a posture in which the rail support portion 64 faces the side of the wife pillar 13. While the other upper rail fasteners 6 are placed in the opposite posture and the attachment surface portions 62 and 62 are brought into contact with each other, the lower end corner portion of each upper rail 4 is locked by the tip end portion 64a of the rail support portion 64 of each upper rail fastener 6. In addition, the two upper rails 4 and 4 are held between the two opposing rail support portions 64, and at the abutting portions between the mounting surface portions 62 and 62 of the pair of upper rail fasteners 6 and 6, An intermediate member 9 that is gradually tapered from the base portion to the tip portion is interposed, and in this state, the U bolt 7 is inserted into the insertion hole 61 provided in the box-type base portion 60 of each upper rail fastener 6 from the rear of the end post 13. Insert, using thumbscrews 70, 70 Firmly on the rail fasteners 6, 6 on a pair To be secured to the wife pillar 13.

  As shown in FIG. 13, the intermediate member 9 includes a head 90 having an inner surface 91 that matches the radius of the bent portion between the upper surface portion 65 and the mounting surface portion 62 of the upper rail fastener 6, and the head 90. And a wedge-shaped body plate portion 92 that gradually tapers from the base portion to the tip portion on the head side. The body plate portion 92 includes a plurality of insertion holes 61 provided in the upper rail fastener 6. A communication hole 61 'corresponding to each size and positional relationship is provided.

  This intermediate member 9 can also be used when the lower rails 5 are arranged in two. By using the intermediate member 9, when the U bolt 7 is tightened with a thumbscrew 70, the intermediate member 9 has a wedge shape. , The lower ends (upper ends) of the upper rails 4 and 4 (lower rails 5 and 5) are strongly pressed to each other, and the rails are not separated but receive a force in the close contact direction. In particular, the upper rails 4 and 4 can prevent the drop-off from the rail fastener 6 as much as possible.

  Further, even in the case of the double sliding door mounting structure as described above, the rail fastener 6 has a box composed of mounting surface portions 62 and 62 through which the U bolts 7 are inserted, an upper surface portion 65, and a rail contact surface portion 63. Since the rigidity of the mold base portion 60 is extremely high, the rail support portion 64 does not warp regardless of the tightening amount of the thumbscrew 70, and the two upper rails 4 and 4 are securely held. Even when the sliding door 3 is attached to each upper rail 4, the state in which the sliding door 3 is firmly held is maintained, and problems such as rail dropping do not occur.

  This is a case where a double sliding door mounting structure is constructed by adding new upper and lower rails 4 and 5 to the entrance 2 of the existing vinyl house 1 while keeping the existing upper and lower rails 4 and 5 as they are. However, the rail fastener 6 having the configuration according to the present embodiment can be used.

  For example, as shown in FIG. 11, when the existing upper rail 4 is attached to the post 13 by the rail fastener 6, the existing upper rail 4 and the new upper rail 4 are located at a position avoiding the post 13. '' Are fixed by rail fasteners 6. That is, the newly installed upper rail 4 ″ is directly attached to the existing upper rail 4 via the rail fastener 6, not to the end pillar 13.

  In this case, one rail fastener 6A (see FIG. 11 (b)) with the double U-bolt 7 mounted in advance so as to wrap the existing upper rail 4 already fixed to the post 13 ), And the other rail fastener 6B (see FIG. 11 (b)) is attached to the protruding U-bolt 7 in a state where the new upper rail 4 ″ is held in parallel with the existing upper rail 4. In this state, the new upper rail 4 ″ is held while being inserted, and fastened with the thumbscrew 70 in this state. In this way, the new upper rail 4 ″ can be easily retrofitted without removing the existing upper rail 4, and the construction can be simplified in a very short time. In the example shown in FIG. 11, the existing upper rail 4 and the new upper rail 4 ″ have the same shape. However, for example, when the shapes and sizes of the two are different, they are shown in FIGS. 10 and 14. Thus, what is necessary is just to prepare two types of rail fasteners 6 and 6 corresponding to each rail. 10 and 14, 4 'is an existing rail having a different shape, and 6 "is a rail fastener corresponding to the existing rail 4'.

  As described above, according to the present embodiment, when a double sliding door mounting structure is constructed, there is no need for a dedicated bracket for rail double connection or the like, and the same rail fastener 6 can be used for two simple operations. A sliding door mounting structure can be realized. In addition, since the existing rail can be left as it is and a new rail can be arranged along the existing rail, a double sliding door mounting structure can be realized at low cost.

  As described above, the present invention has been described through the embodiments. However, the present invention is not necessarily limited to the configurations shown in the above embodiments, and the shape and the like are appropriately determined unless departing from the scope of the claims. The design can be changed.
