Description

  The present invention relates to an improvement of a runner member and a folding door that movably supports a door body along a rail.

  For example, in a folding door in which two doors are hinged so as to be openable and closable, runner members are movably attached along the rails corresponding to the two doors, and the runner members are connected to the doors. The door is connected to the upper end of the side end of the door so as to be movable.

  As this runner member, in the state where the two doors overlap and the folding door is completely opened, the end portions of the runner members arranged on the side end portions of the door bodies are close to each other, There is a structure in which the formed concavo-convex portions are fitted to each other like a male-female bond (for example, see Patent Documents 1 and 2). 6 attached as an explanatory drawing of the present invention shows a state in which the pair of runner members 3 and 3 are fitted, but the one described in the above document is also in a state substantially similar to that in FIG. Mating.

  In the state in which the folding door is completely opened, the end portions of the runner members are fitted to each other in this way, so that the shift in the direction perpendicular to the rail at the end portion of the door body can be regulated. The described runner member has a structure that holds the state in which the end portions are fitted to each other by the engagement of the engagement protrusion and the engagement groove, so that once the folding door is fully opened, The door ends are not naturally separated by the shaking of the door, and the state can be maintained.

  The engaging protrusion is formed at the tip of a spring piece extending from the side end surface of the concavo-convex portion (described as “protruding portion” in the same document) along the rail to the other runner member side. The groove is formed on the side end surface of the protruding portion of the other runner member, and when the end portions of the runner member come close to each other, the tip of the engaging protrusion of one runner member hits the side end surface of the other runner member The spring piece is elastically deformed, and the spring piece is bent and approached when the engaging protrusion reaches the position of the engaging groove, the spring piece is elastically restored and the engaging protrusion is fitted into the engaging groove. It has become.

  Note that the engagement between the engagement protrusion and the engagement groove is such that the door body end portions can be prevented from being naturally separated due to the swinging of the door body. The engagement is released.

  As described above, according to the technique of the same document, the fully opened state of the folding door is maintained with a simple structure, which is highly convenient. There is also a problem in that the pieces and the engaging protrusions are likely to deteriorate over time.

  That is, the spring piece of the runner member is formed as a leaf spring, and its base end is connected to the side end of the protrusion (the protrusion and the spring piece are integrated). If it is caught by the engagement protrusion at the tip, the spring piece may be bent or bent.

  Also, since the engaging protrusion is a small protrusion, the spring piece slightly plastically deforms, the tip of the engaging protrusion wears out, and dust accumulates in the engaging groove as the folding door is repeatedly opened. Then, there is a possibility that the engagement protrusion and the engagement groove cannot be engaged, or even if they can be engaged, they are easily disengaged.

  Thus, since the spring piece and the engaging protrusion are members that are easily deteriorated, worn, or damaged, the runner member needs to be replaced periodically, so that the spring piece can be maintained and replaced more easily and inexpensively. It can be assumed that the projecting portion in which is integrated is separated from the main body portion of the runner member.

The present invention has been proposed in consideration of the problems of the conventional runner members as described above, and the purpose thereof is when the ends of the runner members are fitted to each other when the door is completely open. Furthermore, it is providing the runner member which can be fitted smoothly and can hold | maintain the fitting state between runner members reliably and without shakiness. Moreover, providing the runner member which is hard to deteriorate and wear is also included in the main purpose.

In order to achieve the above object, a runner member according to the present invention is a runner member that supports a door movably along a rail, protrudes in one direction in which the runner member moves, and is mutually connected via a recess. The first protrusion and the second protrusion having a shape that can be inserted into the recess by reversing the direction, and the first protrusion and the second protrusion have one side wall facing the same direction. It is formed on an inclined wall inclined at the same angle, has a tapered shape, and protrudes at the tip of the inclined wall of the first protrusion so as to block a part of the opening of the recess from the wall surface of the inclined wall. convex portions are provided on the proximal end portion of the inclined inclined wall of the second projection, and the engaging recess is provided having an opening in the wall of the inclined wall, the width of the tip of the second protrusion is engaged to being smaller than the width of the opening of the recess portion is blocked by the convex portion .

  By configuring the runner member in such a configuration, the runner member is configured such that the end portions where the first and second protrusions are formed are opposed to the end portions of the two door bodies adjacent to each other along the rail. When the end portions of the two doors are close to each other, the end portions of the runner members are unevenly fitted, and the engagement convex portion of one runner member and the other runner member are engaged. Since the recess is engaged, the fitted state of the runner member can be maintained. Since the fitting state can be maintained, the fitting does not come off when the door is shaken, and two adjacent doors can be kept stationary in a stable state.

  Moreover, since the 1st, 2nd protrusion becomes the taper shape which formed one side wall as an inclined wall, fitting with the other runner member can be made smooth. In addition, since the opening of the recess is widened by the inclined wall and the tip of the second protrusion that fits into the tapered shape is tapered, the engaging protrusion formed on the tip of the first protrusion or the second protrusion is Reliable uneven fitting can be realized without interfering with the recess of the second protrusion of the runner member.

  Thus, since it is the structure which can carry out smooth uneven fitting of runner members, it can be set as an end part structure which makes it fit in the state without a gap between end parts, and, as a result, a fitting state is changed. It can be maintained without rattling.

  Furthermore, since this runner member is configured not to use a member that is easily deteriorated, worn, or damaged, such as a leaf spring, the runner member can be used without replacing it for a long period of time.

  Moreover, since this runner member can be used for any two adjacent doors if the runner members are rotated halfway to each other, the number of members can be reduced, and as a result, costs such as manufacturing and inventory management can be reduced.

  In the runner member according to the present invention, the first protrusion may have a lightening recess.

  With such a configuration, the first protrusion is easily elastically deformed when the end portions of the runner member are fitted to each other, so that the fitting can be performed smoothly. In addition, since the protrusion is easily elastically deformed, it can be formed into a shape having a small gap between the protrusion and the recess when fitted, and therefore, rattling after fitting can be reduced.

  In addition, the runner member according to the present invention may be configured such that an engagement guide surface is formed at a corner portion on the protrusion tip side of the engagement convex portion.

  According to this configuration, the protrusion provided with the engaging convex portion is smoothly fitted into the recess of the counterpart runner member.

  Furthermore, the runner member according to the present invention may be configured such that a guide surface for releasing engagement is formed at an opening corner portion on the protrusion tip side of the engaging recess.

  According to this configuration, the protrusion provided with the engaging protrusion can be smoothly extracted from the recess of the counterpart runner member.

  The folding door according to the present invention includes a plurality of the runner members described above.

  According to such a folding door, when the folding door is in a completely open state, the end portions of the runner members attached to the two door bodies constituting the folding door are fitted with each other. Since it becomes said structure, the folding door's complete open state can be hold | maintained.

  The runner member according to the present invention is configured as described above so that when the door is completely open and the end portions of the runner member are fitted to each other, the runner member can be smoothly fitted and the runner member The fitting state between them can be securely held without rattling.

It is a figure which shows one Embodiment of this invention, and has shown the bottom view and principal part enlarged bottom view of a pair of runner member attached with respect to a pair of door body of a folding door. In this figure, FIG. 2, and FIG. 3, the state of opening operation of a folding door is shown in time series. It is a bottom view and a principal part enlarged bottom view of a pair of runner members. It is a bottom view and a principal part enlarged bottom view of a pair of runner members. It is a front view of a pair of runner members. It is a side view of a runner member. It is a perspective view which shows the state which each edge part of a pair of runner member engaged with each other.

  Embodiments of the present invention will be described below with reference to the accompanying drawings.

  FIG. 6 is a view showing an embodiment of the present invention. In this figure, a perspective view of a pair of runner members attached to a folding door formed by hinge-connecting a pair of door bodies is shown.

  The folding door 1 is used as a door of a closet or an openable / closable partition between adjacent rooms, and two door bodies 2 and 2 which are hingedly connected to each other have an opening frame (not shown). It is attached between the upper and lower rails 4 (the lower rail is not shown) so that it can be opened and closed.

  In the folding door 1 shown in the present embodiment, in order to allow the two connected door bodies 2 and 2 to move along the rail 4, each door body 2 is on the side not hinged. A runner member 3 movable along the upper rail 4 on the upper portion of the end portion 2a (hereinafter, when distinguishing a pair of runner members 3, one is a first runner member 3 and the other is a second runner member 3). Is attached). The runner member 3 is attached to the upper rail 4 so as to support the door 2 movably along the upper and lower rails 4. In addition, the 1st runner member 3 and the 2nd runner member 3 are the same shapes, and are arrange | positioned so that the same runner member 3 may mutually be reversed and the edge part may face each other.

  The runner member 3 includes a traveling body 3a made of synthetic resin having a substantially rectangular parallelepiped shape, a four-wheel (or three-wheeled) guide roller 3c attached to the traveling body 3a so as to be rotatable in the rail 4, and a traveling body 3a. It is comprised from the rod-shaped connection shaft part 3d protruded below from the lower end center. When the runner member 3 is mounted on the rail 4, the connecting shaft portion 3 d has an axial direction that is vertically downward, and the connecting shaft portion 3 d is rotatably attached to the upper portion of the door body 2. Is attached to the lower rail so that the door 2 can move along the rail 4 in the horizontal direction.

  Moreover, the uneven | corrugated | grooved part 3b is integrally formed in one edge part of the traveling body 3a. When the folding door 1 with the pair of runner members 3 attached to the rail 4 is movably mounted, the concave and convex portions 3b face each other and perform an opening operation, as shown in FIG. When the folding door 1 is completely opened so as to be substantially orthogonal to and overlap with the rail 4, both the runner members 3 are close to each other and the concavo-convex portions 3b are engaged with each other as in actual connection.

  The runner member 3 according to the present invention is characterized by the concavo-convex portion 3b, and the feature points will be described with reference to FIGS.

  1 to 3 are a bottom view and an enlarged bottom view of a main part of the state in which a pair of runner members 3 are attached to the folding door 1, as shown in a perspective view in FIG. The state of the opening operation until reaching the state (see FIG. 3) is shown in time series in the order of the drawing. FIG. 4 is a front view corresponding to the state of FIG. FIG. 5 is an enlarged side view of the runner member 3.

  The concavo-convex portion 3b disposed at the end of the runner member 3 is formed as a concavo-convex ridge that extends in the vertical direction when attached to the upper rail 4, and the concavo-convex ridge includes the first protrusion 10, the second protrusion 20, and these And a recess 30 disposed between the protrusions. As described above, the first and second runner members 3 and 3 of the present embodiment have the same shape, and naturally both the uneven portions 3b and 3b have the same shape.

  As shown in FIG. 6, the runner member 3 has a structure in which end portions constituted by the uneven portions 3 b are engaged with each other. More specifically, the second protrusion 20 of the first runner member (left side in the figure) fits into the recess 30 between the first protrusion 10 and the second protrusion 20 of the second runner member (right side in the figure). In addition, the second protrusion 20 of the second runner member is configured to fit into the recess 30 between the first protrusion 10 and the second protrusion 20 of the first runner member.

  As for this 1st protrusion 10, while the side wall adjacent to the recess 30 is formed in the inclined wall 11, the surface of the other side wall 13 is formed in the surface parallel to the longitudinal direction of the traveling body 3a. The second projection 20 has a side wall 23 surface adjacent to the recess 30 formed in a plane parallel to the longitudinal direction of the traveling body 3 a, while the other side wall has the same angle as the inclined side wall of the first projection 10. It is formed in the inclined wall 21 inclined in the direction.

  That is, the first protrusion 10 and the second protrusion 20 have one side wall surface facing in the same direction and are inclined at the same angle, and have a tapered shape as a whole. The recess 30 disposed between 10 and 20 has a shape in which the opening is wider than the bottom due to the inclined wall 11 of the first protrusion 10. Further, as described above, the recess 30 is fitted with the second protrusion 20 of the other runner member 3, and thus has substantially the same outer shape as the second protrusion 20.

  The reason why the structure including the inclined walls 11 and 21 is as described above is to facilitate the fitting of the concave and convex portions as will be described later, but both the first and second protrusions 10 and 20 are inclined walls. 11 and 21 and the side walls facing the same direction are inclined walls 11 and 21 so that the runner member 3 having the same shape can be used for each of the pair of door bodies 2 and 2. is there.

  And the engagement convex part 12 which protruded in the recessed part 30 side from the inclined surface is formed in the front-end | tip part of the inclined wall 11 of this 1st protrusion 10 so that the opening of the recessed part 30 may be plugged up a little, On the other hand, An engaging recess 22 having an opening 22a (see FIG. 5) on the inclined surface is formed at the base end portion of the inclined wall 21 of the protrusion 20.

  The engaging convex portion 12 and the engaging concave portion 22 are formed at the same time when the concave and convex portion 3b of the first runner member 3 and the concave and convex portion 3b of the second runner member 3 are fitted together. The engaging protrusion 12 of the protrusion 10 is engaged with the engaging recess 22 of the second protrusion 20 of the other runner member 3.

  More specifically, as the folding door 1 is changed from the half-open state to the fully-open state, the two runner members 3 have the concavo-convex portions 3b approaching each other in the direction of the white arrow in FIG. As the second protrusion 20 is inserted into the recess 30 of the other runner member 3 and the folding door 1 is in a completely open state as shown in FIG. 3, the end portions of the runner member 3 are spaced from each other. Fits unevenly. When the second protrusions 20 are inserted into the recesses 30, the engagement protrusions 12 formed on the inclined wall 11 of the first protrusion 10 are engaged with the inclined wall 21 of the second protrusion 20. The recess 22 enters and engages with the recess 22 so that the concave and convex fitting of both the runner members 3 is maintained.

  Thus, since the fitting of the concavo-convex portions 3b is held by the engagement between the engaging convex portion 12 and the engaging concave portion 22, once the folding door 1 is completely opened, the door body 2 swings. The end portions of the door body 2 are not naturally separated by the above, and the state can be maintained until the closing operation is performed.

  In addition, one side wall of the first protrusion 10 and the second protrusion 20 facing in the same direction is formed on the inclined walls 11 and 21 to have a tapered shape, and between the first protrusion 10 and the second protrusion 20. Since the arranged recess 30 has a shape in which the opening is wider than the bottom correspondingly, the end portions can be smoothly fitted to each other.

  That is, as shown in the enlarged view of FIG. 2, the inclined wall 11 of the first protrusion 10 and the inclined wall 21 of the second protrusion 20 of the mating runner member 3 immediately before the insertion of the second protrusion 20 into the recess 30. The distance S is sufficiently wide, and as the proximity between the end portions proceeds, the distance S gradually decreases. However, even when the tip of the second protrusion 20 enters the recess 30, the sufficient distance S Therefore, the second protrusion 20 can be fitted into the recess 30 without being disturbed by the engaging protrusion 12 protruding so as to close the opening of the recess 30.

  In order to securely and smoothly insert the second protrusion 20 into the recess 30 of the other runner member 3 whose opening is narrowed by the engaging protrusion 12 of the inclined wall 11 of the first protrusion 10, the second protrusion It is desirable that the width T1 of the tip of 20 be smaller than the width T2 of the opening of the recess 30 (see the enlarged view on the left side of FIG. 2).

  However, if the engagement guide surface 12b is formed at the corner 12a on the protrusion tip side of the engagement protrusion 12 as shown in the figure, the opening width T2 of the recess 30 and the width of the tip of the second protrusion 20 are provided. Even if there is almost no difference from the dimension T1, the second protrusion 20 can be smoothly fitted into the recess 30. Furthermore, if the engagement release guide surface 22c is formed at the corner 22b on the protrusion tip side of the engagement recess 22 as shown in the figure, the engagement protrusion 12 can be extracted from the engagement recess 22. It can be made smooth, and the fitting cancellation | release between the edge parts of the runner member 3 can also be made smooth.

  Further, in the present embodiment, the first protrusion 10 is formed with a lightening recess 14. In other words, the first protrusion 10 is thinly formed by the thinned recess 14 and has a structure that is easily elastically deformed. When the second protrusion 20 of the other runner member 3 is inserted into the recess 30, the first protrusion 10 is engaged. Even when the opening of the recess 30 is narrowed by the protrusion of the mating convex portion 12, the first protrusion 10 is elastically deformed by the insertion of the second protrusion 20, and the space of the recess 30 is pushed to the first protrusion 10 side. Therefore, the concave and convex fitting between the end portions can be smoothly performed.

  In addition, since the 2nd protrusion 20 is a protrusion pinched | interposed into the 1st protrusion 10 and the 2nd protrusion 20 of an other party runner member when carrying out uneven fitting, the 2nd protrusion 20 does not need to be made into the shape which is easy to elastically deform. Also good. Moreover, in this example, as shown in FIG. 4, the lightening recessed part 9 for material reduction is formed in various places.

  As described above, due to various structural features, the runner members 3 can be smoothly fitted into the recesses and projections so that the end portions can be fitted with no gaps between the end portions. As a result, the fitted state can be maintained without rattling.

  In the embodiment described above, the runner member 3 in which the first protrusion 10 has the engagement protrusion 12 and the second protrusion 20 has the engagement recess 22 is shown. 10 may have an engaging recess, and the second protrusion 20 may have an engaging protrusion. Even in this case, it is desirable to form the thinned recess 14 in the first protrusion 10 so as to be easily elastically deformed.

  Moreover, in embodiment shown above, although the example which attached the runner member 3 to each of the two door bodies 3 and 3 was shown, one door body is fixed to a pillar (vertical frame), and a side edge part It is applicable also to the folding door which attached the fixing member which replaces the said runner member 3 to the upper part of. In that case, if the uneven part of the same shape as the uneven part 3b formed in the end part of the runner member 3 is formed in the end part of the fixed member, the end part of the runner member 3 and the fixed member The fitting state between each other can be maintained.

  Moreover, although the runner member 3 shown above is applied to the folding door 1, it can also be applied to, for example, a sliding door for a partition that can be opened and closed.

  Furthermore, it cannot be overemphasized that the runner member 3 shown to the said embodiment is applicable to a lower rail.
