Description

  The present invention relates to a sill rail, and more particularly to a rail that can adjust the height of the bottom surface of a rail groove.

  Generally, doors for partitioning a room in a house are roughly classified into a door type and a sliding door type, whereas the door type is configured to support the door so as to be rotatable by a hinge or the like. The sliding door type has a configuration in which the upper and lower edges of the door are engaged with rails provided on the duck and the sill and slides along the rails. This sliding door type door is often used when partitioning a Japanese-style room or the like, and the duck and sill and the door frame are often made of wood.

  Therefore, in order to stabilize the open / closed state of the sliding door, it is important to process the rail grooves provided in the duck and the sill, especially the bottom surface of the sill rail, and the height of this rail bottom is not constant. In addition, the sliding of the door is not stable, and there is a case where a gap is generated between the solid edge and the column when the door is closed. Therefore, it was necessary to be processed by a skilled person such as a carpenter or a joinery shop.

  By the way, in a recent house, particularly a wooden house, a method of processing a material to be used in advance (so-called pre-cut) and assembling it as a part is adopted. When such a pre-cut sill is used, it is necessary to adjust the height of the sill rail at the construction site. However, the height adjustment of this sill rail was not easy.

  Therefore, conventionally, a correction device that can adjust the height of the entire sill has been developed (see Patent Documents 1 to 3). However, these techniques adjust the level of the rail portion by adjusting the height of the entire sill, but do not allow adjustment of the long rail itself. On the other hand, as for what adjusts the height of the rail bottom face for each rail, there is one configured to adjust the height of the rail bottom face in several places (see Patent Documents 4 and 5).

JP-A-8-4427 JP-A-9-144433 Japanese Patent Laid-Open No. 11-280341 Japanese Utility Model Publication No.4-28787 Japanese Utility Model Publication No. 6-25487

  The configuration disclosed in Patent Document 4 is to connect the fixing member embedded in the lower part of the sill and the rail with a bolt, and adjust the height of the rail surface according to the height of the bolt head. In the configuration disclosed in Patent Document 5, a rail body having an upper wall and a lower wall is fitted into a groove of a sill, and a screw having a head disposed between upper and lower walls of the rail body is provided at the bottom of the groove. The upper wall was supported by the head of the screw.

  However, both of the above techniques are configured to move the head position up and down by the screw or screw screwing position and adjust the height of the rail surface by the head position, so that the bolt or nut is screwed. It was necessary to form a groove with a height (depth) that could be inserted, and the understructure of the sill was complicated. In addition, since the rail itself was supported only by bolts or screws provided at several locations, the long rail was supported by a small surface of the cross-sectional area of the bolt or screw, so the door The weight of etc. was to be concentrated. Further, the lower part of the rail where the bolts or screws are not provided is hollow, but as described above, the groove is deep, which causes the rail to bend.

  The present invention has been made in view of the above-described points, and the object of the present invention is to provide a sill that can support the rail body in a wide area and can be adjusted in height while making the sill lower part and the groove simple. Is to provide rails.

  Therefore, the present invention is composed of a rail main body mounted in the rail groove of the sill, and a height adjusting member disposed on the back surface of the rail main body. The rail main body includes a long rail surface portion and the rail. The height adjustment member further includes an elevating part and a sliding part, and the elevating part is in contact with the bottom surface of the rail groove of the sill. A lower surface portion and an upper surface portion formed obliquely with respect to the lower surface portion, and the sliding portion is in contact with a sliding surface portion that is in sliding contact with the back surface of the rail body, and an upper surface portion of the elevating portion. The gist of the present invention is a sill rail characterized by comprising a slanted surface portion that maintains the lower surface portion of the elevating portion substantially parallel to the rail surface portion.

  According to the above configuration, the sliding portion is interposed between the rail body and the lifting portion with the sliding contact portion being brought into sliding contact with the back surface of the rail body and the inclined surface portion being brought into contact with the lifting portion. Then, by sliding this sliding part in the longitudinal direction of the rail body, the inclined surface part moves up and down the upper surface of the lifting part. Since the position of the lower surface portion of the elevating part is changed by the elevation of the upper surface, the distance from the lower surface part to the rail surface part is changed. And when the lower surface part of a raising / lowering part closely_contact | adheres to the bottom face of the groove | channel of a rail, the position of an raising / lowering part will become fixed and the height of a rail main body will be adjusted via a sliding part. In addition, in order to slide a sliding part, a sliding part can be directly slid from the adjustment hole provided in the rail surface part.

  The sliding part in the said invention can be set as the structure further provided with the projection part which penetrate | invades into the adjustment hole of the said rail main body.

  According to the said structure, when sliding a sliding part, a sliding part can be slid without using the instrument of the length which reaches a sliding part from the adjustment hole of a rail main body. Moreover, since the projection part slides along the adjustment hole, the sliding part can be slid along the longitudinal direction of the rail body. Then, by providing the protrusions at two positions at appropriate intervals, the posture of the sliding portion is stabilized, and the direction of the inclined surface portion is not changed before and after the sliding.

  Moreover, the raising / lowering part in both said invention can be set as the structure by which at least one is rotatably supported among the longitudinal direction both ends of the said rail main body.

  With such a configuration, the position of the elevating part does not move due to sliding of the sliding part, and even if the height of the lower surface part of the elevating part changes, according to the change By rotating, the support state becomes stable.

  Furthermore, in each of the above inventions, the rail body includes a countersunk screw abutting hole for abutting the countersunk head while inserting a countersunk screw, and the elevating part is provided on an extension line of the through hole. A through-hole through which the countersunk screw can be inserted can be provided, and the sliding portion can have a long hole that allows sliding while inserting the countersunk screw.

  According to the said structure, a countersunk screw will penetrate a rail main body, a sliding part, and an raising / lowering part, respectively, and will be screwed in into the bottom part of the groove | channel of a rail. At this time, until the countersunk head of the countersunk screw is brought into contact with the countersunk screw contact hole of the rail body, the sliding part and the lifting part are moved by the bottom surface of the rail groove and the rail body. Thus, the free sliding of the sliding portion can be suppressed, and the height from the lower surface portion of the elevating portion to the rail surface portion of the rail body can be determined.

  Further, the present invention provides a rail main body mounted on the rail groove of the sill, a height adjusting member disposed on the back surface of the rail main body, and a groove groove bottom surface of the sill while interposing the height adjusting member. The rail body includes a long rail surface portion, an adjustment hole penetrating a predetermined length in the longitudinal direction of the rail surface portion, and the countersunk screw. A countersunk part formed by bending downward both end edges along the longitudinal direction of the rail surface part, and a height adjusting member further comprising: An elevating part disposed in the middle of the opposing piece part of the rail body, and a sliding part interposed between the rail body part and the elevating part and slidable in the longitudinal direction of the rail body, The support is rotatably supported by the opposing piece of the rail body. A lower surface portion that contacts the bottom surface of the rail groove of the sill, an upper surface portion that is formed obliquely with respect to the lower surface portion, and a through-hole through which the countersunk screw is inserted, A sliding contact surface portion that is in sliding contact with the back surface of the rail body, an inclined surface portion that is in contact with the upper surface portion of the elevating portion and maintains the lower surface portion of the elevating portion substantially parallel to the rail surface portion, and the flat head screw are inserted. The gist of the present invention is also a sill rail characterized by having a long hole that allows sliding while having a protrusion that enters the adjustment hole of the rail body.

  According to the above configuration, the elevating part and the sliding part are accommodated in a substantially U-shaped internal space formed by the rear surface of the rail surface part of the rail body and the opposing surface of the opposing piece part. And if the rail surface part is adjusted so that the rail surface part is at the lowest position with the distance from the leading edge of the opposing piece part to the rail surface part, that is, the length dimension of the opposing piece part, it is lifted and lowered only when the rail surface part is raised. The part protrudes outward from the edge of the opposing piece part. Therefore, in the case where a rail groove that has been precisely machined to such an extent that height adjustment is not required, it is supported not only by the lower surface portion of the elevating part but also by the edge of the opposing piece part.

  And in the state where the countersunk screw passes through the rail body and also the lifting part, the countersunk screw will pass through the long hole of the sliding part. The sliding portion can be finely adjusted at the stage before the clamping state by the countersunk screw is completed. In addition, since the protrusion part of the sliding part has penetrate | invaded into the adjustment hole of a rail main body, the longitudinal direction of the long hole of a sliding part is provided in parallel with the longitudinal direction of the said adjustment hole.

  The raising / lowering part in the said invention is integrally shape | molded by the synthetic resin, and the said support part can be comprised by this synthetic resin so that elastic deformation is possible.

  According to the above configuration, the elevating part can be provided with two or more support parts from both ends in the longitudinal direction of the rail body, and the sliding part interposed between the rail body and the rail body can be temporarily fixed. it can. That is, when the elevating part moves up and down, the distance from the position where the support part is supported to the elevating part slightly expands and contracts, so that it can be elastically deformed according to the expansion and contraction. And by arrange | positioning a sliding part in the middle of the position supported by this support part, a sliding part is clamped between an raising / lowering part and a rail main body back surface, and is controlled by the opposing piece part, and slides. It can suppress that a part leaves | separates from a rail main body and a raising / lowering part.

  According to the present invention, the height of the sill rail is determined by the thickness of the sliding part and the lifting part, and the height can be easily adjusted by sliding the sliding part. Moreover, since the lower part of a sill rail should just have the groove | channel which the lower surface part of an raising / lowering part can contact | abut, the sill rail which can adjust height can be comprised, without requiring a complicated structure. Furthermore, the thickness of the lifting part and the sliding part depends on the inclination angle of the upper surface part of the lifting part formed obliquely and the oblique surface part of the sliding part also formed obliquely, This inclination angle can be varied depending on the height that needs to be adjusted, but it does not change remarkably, and in order to gradually change the height, the inclination angle becomes gradual and, as a result, the wall thickness becomes thin. There is no need to machine the rail grooves deeply.

  Furthermore, at the position where the height of the rail is adjusted, the lower surface of the elevating part comes into contact with the bottom of the groove of the rail as described above, so that the rail body can be supported in a wide area. Therefore, it is possible to reduce the hollow portion between the bottom of the rail groove and the rail body. Also, unlike the case where the height is adjusted by rotating the bolt or screw (forward / reverse rotation), the bolt or screw is not rotated by vibration, etc., and the height does not change. Even in the present invention, even if the countersunk screw is rotated, it is not a direct factor for changing the height. Furthermore, since the sliding portion can be slid before the clamping by the countersunk screw, the rail can be fixed while performing fine adjustment. In addition, the height of the rail is adjusted only by sliding the sliding part. The sliding part is slid directly from the adjustment hole of the rail body, or the sliding part is operated by operating the protrusion entering the adjustment hole. Therefore, the height of the rail can be adjusted by a very easy operation.

(A) is explanatory drawing when the position of a rail main body is made into a low state, (b) is explanatory drawing when it makes it a high state. It is explanatory drawing which shows a 2nd actual form. It is explanatory drawing which shows a modification.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is an exploded perspective view showing an outline of the present embodiment. As shown in this figure, the sill rail of this embodiment includes a rail main body 1 to be mounted in rail grooves B and C of a wooden sill A, and a height adjusting member 2 for adjusting the height of the rail main body 1. The height adjusting member 2 is further composed of an elevating part 3 and a sliding part 4. Although the figure shows only one sill rail for the two rail grooves B and C, in practice, one sill rail is provided for each of the rail grooves B and C. Further, a sliding contact tape (not shown) is attached to the surface side of the rail body 1 at the time of finishing, has a color corresponding to the wooden material constituting the sill, and forms irregularities on the surface. The finished surface of the rail is constituted by a structure having a small friction coefficient.

  The rail body is provided with opposing pieces 12 and 13 which are long in the longitudinal direction on both sides of a long rectangular flat surface portion (hereinafter referred to as rail surface portion) 11, and the entire rail body 1 is traversed. The surface shape is formed in a substantially U-shape. A long hole (hereinafter referred to as an adjustment hole) 14 that is elongated in the longitudinal direction is provided in the rail surface portion 11 of the rail body 1 so that the adjustment hole is operated when the sliding portion 4 is operated. The sliding part 4 can be reached via 14. A tapered round hole (hereinafter referred to as a countersunk screw contact hole) 15 is provided in the vicinity of the adjustment hole 14 so that a countersunk screw (wood screw having a countersunk head) 5 can be inserted therethrough. 51 can contact | abut to a periphery.

  The elevating part 3 constituting the height adjusting member 2 has a main body portion 30 formed of a thin rectangular parallelepiped, the longitudinal direction coincides with the longitudinal direction of the rail body 1, and the width dimension is an opposing piece of the rail body 1. The parts 12 and 13 are configured to be smaller than the opposing width dimension, and can be accommodated inside the opposing piece parts 12 and 13 as a whole. Support portions 33 and 34 are provided at both ends in the longitudinal direction of the main body portion 30, and locking portions 33 a and 34 a are provided at the tips of the support portions 33 and 34. Supported and pivotally supported.

  Further, a flat surface portion 35 is provided on the side of the main body portion 30 where the upper surface portion 32 is provided. Depending on the position of the sliding portion 4, the flat surface portion 35 directly contacts the back surface 16 of the rail main body 11. You can come in contact. Further, on both sides in the width direction of the upper surface portion 32 formed in an oblique shape, there are provided restricting portions 36 and 37 having a height continuous with the flat surface portion 35, and the sliding portion 2 that contacts the upper surface portion 32. Is regulated (details will be described later).

  Further, a through hole 38 is provided in a portion where the upper surface portion 32 of the elevating part 3 is formed, and when the countersunk screw 5 described above is inserted into the countersunk screw contact hole 15 of the rail body 1, The screw portion 52 of the screw 5 can be inserted. Accordingly, when the elevating part 3 is mounted on the rail body 1 by the support parts 33 and 34, the center of the countersunk screw contact hole 15 of the rail body 1 and the center of the through hole 38 of the elevating part 3 are on the same straight line. The positions of both holes 15 and 38 are adjusted so that

  In addition, the said raising / lowering part 3 is integrally comprised by the product made from a synthetic resin, and since the main-body part 30 raises / lowers, it is comprised so that the support parts 33 and 34 can expand and contract a little. Further, as the main body 30 is moved up and down, the longitudinal angle of the support portions 33 and 34 slightly changes. However, the boundary between the main body 30 and the support portions 33 and 34, and the support portions 33 and 34. A fine notch is provided at a boundary portion between the locking portions 33a and 34a and is configured to be easily bent according to an angle change.

  The sliding portion 4 constituting the height adjusting member 3 is provided with a slanted surface portion 41 that comes into contact with the upper surface portion 32 of the lifting / lowering portion 3, and is appropriately extended along the longitudinal direction of the rail body 1 on both sides thereof. Sliding contact surface portions 42 and 43 having a thickness are provided. The sliding contact surface portions 42 and 43 are formed in a thin plate shape, and the upper surface side of the sliding contact surface portions 42 and 43 contacts the rear surface 16 of the rail body 1, and the lower surface side thereof contacts the regulating portions 36 and 37 of the elevating unit 3. It touches. Accordingly, by interposing the sliding portion 4 in the middle between the rail body 1 and the lifting / lowering portion 3, the sliding contact surface portions 42 and 43 are placed between the rear surface of the rail body 1 and the regulating portions 36 and 37 of the lifting / lowering portion 3. It will be located. The inclined surface portion 41 comes into contact with the upper surface portion 32 of the elevating portion 3 in the middle of the regulating portions 36 and 37 of the elevating portion 3, and the inclined surface portion 41 contacts only the upper surface portion 32 of the elevating portion 3. It will be.

  Further, the sliding portion 3 is provided with a tongue piece portion 44 continuous with the inclined surface portion 41, and further provided with projecting portions 45 and 46 protruding from a part of the tongue piece portion 44 toward the rail body 1. It has been. One protrusion 45 is bent vertically and sufficiently enters the adjustment hole 14 of the rail body 1, and the other protrusion 46 is bent in an oblique direction to adjust the rail body 1. It partially penetrates the hole 14. The projecting portions 45 and 46 may have the same projecting direction and projecting length. However, in order to clarify the projecting portion 45 for operating sliding, a configuration in which one projecting portion 45 is sufficiently invaded. It is said. In addition, these protrusion parts 45 and 46 function also as a stopper for restricting the sliding range of the sliding part 4, and also in a state of entering the adjustment hole 14 of the rail body 1, The protrusion length is adjusted so that the tip does not protrude from the surface of the rail surface portion 11.

  Further, a long hole 47 having a predetermined length along the longitudinal direction of the rail body 1 is provided in the oblique surface portion 41 of the sliding portion 3. The long hole 47 is for the threaded portion 52 of the countersunk screw 5 to be inserted therethrough, but the countersunk screw 5 is also inserted through the through hole 38 provided in the upper surface part 32 of the elevating part 3 at the same time. It is provided on the inclined surface portion 41 that comes into contact with the upper surface portion 32. The longitudinal direction of the long hole 47 also coincides with the direction in which the entire sliding portion 4 slides, restricts the direction in which the sliding portion 4 slides, and allows the sliding portion 4 to slide. It is also what determines the range.

  Therefore, the relationship between the long hole 47 and the countersunk screw 5 and the relationship between the protrusions 45 and 46 and the adjustment hole 14 are such that when the countersunk screw 5 is inserted into the countersunk screw contact hole 15 of the rail body, the countersunk screw 5 The two projecting portions 45 and 46 are adjusted so as to stop at both ends of the adjusting hole 14 so as to be surely inserted through the long hole 47.

  Since the structure of each part forming this embodiment is as described above, in order to mount the height adjusting member 2 on the rail body 1, the sliding part 4 is moved up and down with the rail body 1 as shown in FIG. The lifting / lowering part 3 is mounted on the rail body 1 by the support parts 33 and 34 of the lifting / lowering part 3 while being interposed in the middle of the part 3. Thereby, the sliding part 4 will be mounted in a state of being sandwiched between the rail body 1 and the elevating part 4.

  At this time, the main body 30 of the elevating unit 3 is positioned in the middle of the opposed pieces 12 and 13 of the rail main body 1, and the movement is restricted in the width direction of the rail main body 1. The movement of the inclined surface portion 41 in the width direction is also restricted by the restriction portions 36 and 37 of the elevating portion 3. And since the sliding range of the sliding part 4 will be controlled by the protrusion parts 45 and 46, the sliding part 4 moves to the longitudinal direction of the rail main body 1 to the position which can remove | eliminate clamping by the raising / lowering part 4. There is nothing.

  Therefore, in this state, by moving the sliding portion 4 in the longitudinal direction of the rail body 1, the inclined surface portion 41 of the sliding portion 4 enters between the rail body 1 and the lifting portion 4 like a wedge. This causes an interval between the two. Therefore, in order to adjust the height of the rail, it is necessary to move the sliding portion 4 so as to enter as a wedge. Therefore, in the following description, moving in the direction in which the wedge enters will be described as moving forward, and moving in the opposite direction will be described as moving backward.

  Next, usage modes of the present embodiment will be described. 3A shows a state where the rail surface portion 11 of the rail body 1 is at the lowest position, and FIG. 3B shows a state where the rail surface portion 11 of the rail body 1 is at the highest position.

  As shown in FIG. 3A, when the rail surface portion 11 is set to a low position, the sliding portion 4 is moved backward (moved in the right direction (see arrow) in the figure). In this state, there is no gap between the rail body 1 and the lifting / lowering part 3, the flat part 35 configured in the body part 30 of the lifting / lowering part 3 is in contact with the back surface 16 of the rail surface part 11, The position of the lower surface 31 coincides with the positions of the front end edges 12 a and 13 a of the opposing piece portions 12 and 13 of the rail body 1. Accordingly, the rail body 1 is supported by the opposing piece portions 12 and 13 at both ends in the width direction, and is supported by the body portion 30 of the elevating unit 3 at the center. In this state, the height of the rail surface portion 11 of the rail body 1 is fixed by inserting the countersunk screw 5 and screwing it into the rail grooves B and C of the sill.

  On the other hand, when the rail surface portion 11 is set at a high position, as shown in FIG. 3B, the sliding portion 4 is moved forward (moved in the left direction (see arrow) in the figure). By the advance of the sliding portion 4, the inclined surface portion 41 of the sliding portion 4 pushes down the upper surface portion 32 of the elevating portion 3, and a gap H is generated between the rail body 1 and the elevating portion 3. At this time, a part of the inclined surface part 41 of the sliding part 4 and a part of the upper surface part 32 of the elevating part 3 are in contact with each other, and the lower surface part 31 of the elevating part 3 is in contact with the rail grooves B and C. Thus, the rail body 1 is raised by the height corresponding to the gap H. In addition, by inserting the countersunk screw 5 and screwing it into the rail grooves B and C, the elevating part 3 and the sliding part 4 are sandwiched between the rail body 1 and the rail grooves B and C. As a result, the sliding portion 4 is restricted from freely sliding, so that the height of the rail body 1 can be maintained.

  As shown in FIGS. 3A and 3B, bent portions are provided in the vicinity of both ends of the support portions 33 and 34, and the elevating portion 3 is raised and lowered (particularly lowered). When this is done (the gap H is generated), the bending angle will change, but by providing the cut grooves 33b, 33c, 34b, 34d inside the bent portion, the angle can be easily changed. . Although not clearly shown in the drawing, when the elevating part 3 is lowered, the lengths of the support parts 33 and 34 are slightly extended, but this is made possible by the elastic deformation of the synthetic resin. ing. And since this elastic force has a restoring force, when retracting the sliding part 4, the raising / lowering part 3 will move so that the rail main body 1 may be approached.

  Next, the 2nd actual form of this invention is demonstrated. The present embodiment has the same configuration as that of the above-described embodiment, but is a configuration in which the elevating part 3 is supported on the rail body 1 by only one support part 33. In the case of such a configuration, when the rail body 1 is taken out from the rail grooves B and C, the sliding portion 4 is separated from the height adjusting member 2 (the lifting portion 3 and the sliding portion 4). However, this makes it possible to replace the sliding portion 4. That is, the height of the rail body 1 is substantially adjusted by the thickness dimension of the inclined surface portion 41 of the sliding portion 4. Therefore, in order to greatly raise the rail body 1, this thickness dimension The sliding part 3 having the large inclined surface part 41 may be used. Therefore, it is suitable when the sliding part 4 having such dimensions is exchanged at the construction site.

  Even when the elevating part 4 is supported by the one support part 33 as described above, the elevating part 3 cannot be moved in the vertical direction by the sliding part 4 and the rail grooves B and C in use. In addition, as a result of the slanting surface portion 41 of the sliding portion 4 abutting in the oblique direction, a lateral force is applied to the elevating portion 3, but the lateral movement is restricted by the one support portion 33. Thus, the position of the elevating part 3 is stabilized. And when using such a support part, since it is not necessary for the support part 33 to expand-contract according to the raising / lowering of the raising / lowering part 3, this support part 33 is comprised with the material which does not elastically deform, Also good.

  The embodiment of the present invention is as described above, but the present invention is not limited to the above embodiment. Accordingly, various forms can be taken without departing from the spirit of the invention. For example, in the embodiment described above, the rail body 1 has a U-shaped cross section, and the elevating part 3 is supported by at least the support part 33. However, the rail body 1 is configured by a plate-like member. Alternatively, the elevating part 3 may not be supported by the support part.

  An example of such a modification is shown in FIG. As shown in this figure, the rail body 101 is formed in a flat plate shape, and is provided with a rail surface portion 111 and an adjustment hole 114. On the back surface 112 of the rail body 101, a frame body 106 for positioning the elevating part 103 is provided. The frame body 106 is provided to prevent the sliding portion 104 from moving sideways when the lifting portion 103 is pushed down. Further, since the frame body 106 is also present on both sides in the width direction of the elevating unit 103, it is not necessary to provide a facing piece on the rail body 101. In the above example, each part and the rail groove are fixed with flat screws, but each part may be fixed with an adhesive or the like instead of using flat screws. After the position of 104 is adjusted, the contact portion is bonded, and naturally, the flat screw contact hole is not necessary. Although the above is a modification, naturally it is not restricted to this.
