Description

  The present invention engages with a concave groove formed in the moving direction of the upper hanging door (hereinafter referred to as the left-right direction) on the lower end surface of the upper hanging door, and a direction perpendicular to the left-right direction (hereinafter referred to as the left-right direction). This is related to a lower guide with front-rear direction adjustment that enables position adjustment in the front-rear direction.

An adjustment device (front and rear) that is disposed on the floor surface, for example, on the floor surface to reduce the swinging of the upper and lower sliding doors in order to engage with the left and right concave grooves formed on the lower end surface of the upper sliding door. Conventionally, the lower guide with direction adjustment is known (Patent Documents 1 and 2).
For example, as shown in FIG. 6, in the steadying structure for a hanging door of Patent Document 1, the adjustment base 105 is placed in a fastening position on the floor surface determined by a predetermined procedure with the adjustment base 105 positioned on the lower surface. Then, the fastening seat 106a of the guide base 106 is positioned. In this state, the first screw 107 is screwed into the floor surface through the front and rear screw holes 106b to fix the guide base 106. Next, after adjusting the front / rear position of the adjustment base 105 so that the anti-roll roller 108 is positioned substantially at the front / rear center of the guide base 106, the second screw 110 inserted into the screw insertion hole 109 a of the clamp piece 109 is inserted into the screw long hole. It is screwed to the floor surface through 105a to a midway position and temporarily fixed. At this time, the adjustment base 105 is guided so as to be slidable back and forth between the guide base 106 and the floor surface, and can be moved in the front-rear direction. Then, after temporarily fixing, the door panel 100 is hung on the guide rail 101, and when the door panel 100 is opened and closed several times by engaging the swing rail 102 with the swing roller 108, the center of the swing roller 108 is obtained. The position can be matched with the center position of the guide rail 101. As described above, after the anti-roller roller 108 is positioned on the door panel 100, the second fixing screw 110 is screwed to the end with the adjustment base 105 held and fixed, thereby fixing the adjustment base 105 to the front and rear. It is fixed.)
FIG. 6A is a longitudinal front view of the above-described swing prevention structure, FIG. 6B is a longitudinal side view of the sliding door, and FIG. 6C is an exploded perspective view of the above-described swing prevention structure.

Further, for example, as shown in FIG. 7, in the swing door anti-skid device of Patent Document 2, the disk-shaped member 203, the counter gear 204, and the adjustment gear 205 as the position adjustment mechanism 202 are engaged with each other in the horizontal direction. The disc-shaped member 203 can be rotated by accommodating the recess in the base member 201 and rotating the adjusting gear 205. In this case, the disk-shaped member 203, the counter gear 204, and the adjustment gear 205 are arranged so that their respective axes are on a straight line. Then, the support shaft 207 of the guide portion 206 is fixed to the disc-shaped member 203 at a position biased toward the periphery rather than the axis of the disc-shaped member 203 via the mounting hole 203a. Therefore, when the disk-shaped member 203 is rotated, the support shaft 207 draws an arcuate locus on the disk surface of the disk-shaped member 203 (along the insertion hole 208a of the lid member 208 ( C)))), and the position of the sliding door 200 with respect to the front-rear direction (the arrow direction in FIG. 5A) can be adjusted.
FIG. 7A is a perspective view of the above-described anti-seismic device, FIG. 7B is a plan view showing a state in which the lid member of the above-mentioned anti-vibration device is removed, and FIG. 7C is a back view of the lid member. is there.

  However, the above-described swing stopper structure for the sliding door of Patent Document 1 allows the center position of the swing roller 108 to coincide with the center position of the guide rail 101 only by opening and closing the door panel 100 several times after temporarily fixing. However, if these center positions do not coincide with each other, the anti-roller roller 108 is directly touched to the anti-roller roller 108 or the adjustment base 105 on which the guide base 106 is overlapped is inserted through a tool. Since it must be pushed, there is a problem that workability is not good and time is required for the work. In addition, a hanging door whose top end is closed, that is, a hanging door in which both ends of the groove formed in the moving direction of the hanging door are closed (for example, FIG. 4B). In addition, it goes without saying that the swing roller 108 cannot be directly touched and pushed. Further, in this steady rest structure, if the number of times the second screw 110 is screwed or loosened on the floor surface by repeating temporary fixing and permanent fixing until the center positions coincide with each other, sag in the thread groove on the floor surface. There is a problem that the fixed state does not work. In particular, since the second screw 110 is screwed obliquely with respect to the floor surface, there is a problem that the above-mentioned sag is likely to occur.

Further, the swing door anti-skid device of Patent Document 2 operates the gear train including the disk-like member 203 connected to the adjustment gear 205 by rotating the adjustment gear 205, so that the upper surface of the disk-like member 203 is operated. The above-mentioned position adjustment is performed by using the guide portion 206 provided at the eccentric position of the arc to move along an arcuate locus, and a gear train must be constituted by a plurality of gears. Therefore, the apparatus itself becomes large, and it is difficult to simplify and reduce the cost. In particular, the distance between the position of the adjustment gear 205 and the position of the guide portion 206 on the disk-like member 203 for improving workability. When it is desired to take longer, it is necessary to increase the number of gears in the gear train, and there is a problem that it is difficult to simplify and reduce costs. It is also possible to manufacture the gear with a thin steel plate, but a certain amount of wall thickness is required to ensure meshing and to provide strength. When the ground height of the adjustment part of the device increases (thickness) and the device is directly installed in the passage on the floor surface, there is a problem that disturbs people coming and going.
JP2013-249589 (7th to 8th pages, FIGS. 1, 3 and 4) JP-A-2000-352258 (pages 2 and 3, FIGS. 1, 2, and 4)

  The problem to be solved is that the lower guide with the front-rear direction adjustment as an adjusting device for reducing the front-back swing of the upper sliding door has good workability in adjustment and does not require work time. It is possible to simplify itself and reduce costs, and to suppress the height of the ground at the adjustment part of the device and to have a structure that does not interfere with human access when the device is installed directly in the passage on the floor surface. It is a point to do.

  A lower guide with front-rear direction adjustment of an upper hanging door according to claim 1 of the present invention is fixed to a floor surface facing the lower end surface of the upper hanging door, and engages with a groove formed in the left-right direction of the lower end surface. A lower guide with a front / rear direction adjustment of the upper sliding door that enables position adjustment with respect to the front / rear direction of the upper sliding door, wherein the long axis forms a predetermined angle with respect to the left / right direction, and the long axis Are formed on the upper surface side, and the oval gate groove hole is inserted on the floor surface while the adjustment screw for adjusting the position is inserted therethrough. A base member having a lower surface side fixed and forming a gap between the upper surface side and a screw hole into which the adjustment screw is screwed are provided, while the gap of the base member is provided with the screw of the adjustment screw. Along with the movement in the left-right direction, the left-right direction and A connecting member that is accommodated so as to be movable in the rearward direction and is fixed to the base member by screwing the adjusting screw into the screw hole; one end fixed to the connecting member; and the other end Is provided with a guide member that extends through the oval guide groove hole of the base member into the concave groove of the upper hanging door and engages with the concave groove. When adjusting the position of the direction, if the adjusting screw is moved along the oval gate groove hole of the base member, the guide member is guided and moved by the oval guide groove hole of the base member. Since the members and connecting members move in the left-right direction and the front-rear direction, it is possible to adjust the position to reduce the swinging of the upper sliding door in the front-rear direction, and when the adjustment is completed, the adjustment screw is screwed into the screw hole. Then, the connecting member is Is fixed to the member, there have been positioned in this case the guide member.

  According to the lower guide with adjustment in the front-rear direction according to such a configuration, the adjustment can be completed by moving and screwing the adjustment screw, so that the workability in the adjustment is improved and the work time is not required. In addition, since the gear train is not arranged as in the conventional device, for example, the device itself can be simplified and the cost can be reduced. Further, the upper surface side and the lower surface of the base member can be achieved. Since the gap is formed between the side and the connecting member that can move in the left-right direction and the front-rear direction is accommodated in the gap, the ground height at the adjustment part of the device is suppressed, and the device is placed on the floor surface. When installing directly in the passage, it is possible to prevent the person from getting in and out.

  The lower sliding guide with the front / rear direction adjustment of the upper sliding door according to the present invention has good workability in adjustment, does not require work time, simplifies and lowers the cost of the device itself, and is used in the adjustment part of the device. There is an advantage that the height of the ground is suppressed and the device is not disturbed when people go in and out when the device is installed directly in the passage on the floor.

A lower guide with front-rear direction adjustment of the upper sliding door according to the embodiment of the present invention will be described with reference to FIGS.
As shown in FIG. 1, the lower guide 1 with the front and rear direction adjustment of the upper sliding door is disposed at an appropriate position on the floor surface facing the lower end surface of the upper hanging door 2. It is possible to adjust the position in the front-rear direction (arrow C, D direction in the figure) with respect to the upper hanging door 2 by engaging with the recessed groove 2a formed in the A and B directions, and in this direction. It is to make. The drawing shows a state in which the upper suspension door 2 is closed, and a guide member described later extends into the groove 2a of the upper suspension door 2 and engages with the groove 2a. A substantially half portion of the lower guide 1 including the guide member is opposed to the lower end surface of the upper suspension door 2, and the other approximately half portion including an adjusting screw described later protrudes to the passage side.

A specific configuration of the lower guide 1 with front-rear direction adjustment of the upper sliding door will be described with reference to FIG. 2A is an assembly view of the lower guide 1, and FIG. 2B is an exploded perspective view of the lower guide 1.
The lower guide 1 includes a base member 3 fixed to the floor surface, a connecting member 4 accommodated in a gap 3c of the base member 3, and a guide member 5 fixed to the connecting member 4. It is a simple one.

Of these, the base member 3 is a molded product that is formed in a thin and substantially rectangular shape with the lower surface 3b (see FIG. 3) side opened, and a portion near one end on the upper surface 3a side is a small truncated cone. An elliptical gate groove hole 6b through which an adjustment screw 7 for adjusting the position of the upper sliding door in the front-rear direction is inserted in the center of the truncated cone 6a. The major axis of the gate groove hole 6b is The base member 3 is provided so as to face the longitudinal direction, that is, the left-right direction.
Furthermore, countersunk screw holes 6c and 6d are provided on the upper surface 3a of the base member 3 at a position near the center and the other end thereof. These countersunk screw holes 6c and 6d fix the base member 3 to the floor surface. This is an insertion hole for a countersunk screw (not shown).
Furthermore, an oval guide groove hole 6e through which the guide member 5 is inserted in a substantially intermediate portion of the countersunk screw holes 6c and 6d has a long axis of the guide groove hole 6e with respect to the longitudinal direction of the base member 3. That is, it is provided so as to form a predetermined angle with respect to the left-right direction. The oval guide groove 6e functions to guide the guide member 5 during the position adjustment, and allows the connecting member 4 to move in the front-rear direction (in this case, not only the front-rear direction but also the left-right direction). Also move).
By the way, the base member 3 is fixed to the floor surface with a countersunk screw as described above. At this time, the upper surface 3a side of the base member 3 and the lower surface 3b side of the base member 3 arranged on the floor surface. A very thin gap 3c is formed between the connecting member 4 and the gap 3c (see FIG. 3).
In addition, as shown in FIG. 2 etc., the scale s is displayed on the truncated cone 6a of the base member 3, so that the adjustment screw 7 is moved when the position is adjusted.

Further, since the connecting member 4 is a member accommodated in the gap 3c of the base member 3 as described above, the connecting member 4 is a plate-like material having an extremely thin and substantially rectangular shape. In the present embodiment, a ring-shaped receiving base 8 is fixed to a portion near one end on the upper surface side, and a screw groove for screwing the adjusting screw 7 is screwed into the receiving base 8. The thread groove is formed to be continuous with the screw hole 4c (see FIG. 3B) provided in the connecting member 4, so that the screwing length with the adjusting screw 7 is sufficiently secured. I have to. The connection member 4 is fixed to the base member 3 by the adjustment screw 7 screwed into the screw groove of the cradle 8 and the screw hole of the connection member 4, while the adjustment screw 7 is loosened and the adjustment is performed. When the screw is moved in the left-right direction, the connecting member 4 is moved in the left-right direction and the front-rear direction.
Further, one end of the guide member 5 is fixed to the portion near the other end on the upper surface side, for example, by caulking the end portion.
Furthermore, a countersunk screw (not shown) for fixing the base member 3 inserted through the countersunk screw hole 6c of the base member 3 through a substantially intermediate portion between the cradle 8 and the guide member 5 is inserted. An oblong insertion hole 4a is provided as a hole, and the long axis of the insertion hole 4a is a predetermined angle with respect to the longitudinal direction of the connecting member 4, that is, the left-right direction (this predetermined angle is the guide groove of the base member 3). It is the same as the angle formed by the long axis of the hole 6e). The insertion hole 4 a is formed in an oval shape to prevent interference with a countersunk screw (not shown) for fixing the base member 3. In addition, although the substantially concave notch is given to the edge part of the connection member 4 near the guide member 5 standing upright, this is inserted through the countersunk screw hole 6d of the said base member 3. In order to prevent interference with a countersunk screw (not shown) for fixing the base member 3.

Further, the guide member 5 is simply a long columnar member in the present embodiment, and one end of the guide member 5 is fixed to the connecting member 4 as described above, while the other end is the base member 3. When the lower guide 1 is disposed at an appropriate position on the floor surface facing the lower end surface of the upper suspension door 2 through the oval guide groove hole 6e, it extends into the recessed groove 2a of the upper suspension door 2 and A mode of engaging with the concave groove 2a is adopted.
For example, a rolling wheel (not shown) may be attached to the other end of the guide member 5.

Next, the operation of the lower guide 1 will be described with reference to FIG.
When the position of the upper suspension door 2 is adjusted in the front-rear direction when the upper suspension door 2 is closed as shown in FIG. 1, first, the guide member 5 in the recessed groove 2 a of the upper suspension door 2 is firstly displayed. Checking the engagement position by checking whether the guide member 5 is in contact with the concave groove 2a or opening / closing the upper suspension door 2 several times to confirm the weight of the opening / closing operation of the upper suspension door 2 Thus, the one-side contact state of the guide member 5 with respect to the concave groove 2a is grasped. Thereafter, the position adjustment may be performed so that, for example, the guide member 5 is positioned approximately at the center of the concave groove 2a.
Here, for convenience of explanation, the guide member 5 is actually in a state of being in contact with the concave groove 2a, and the adjustment screw 7 and the guide member 5 of the lower guide 1 at that time are in the state shown in FIG. It is assumed that the screw 7 is in the approximate center of the gate groove hole 6b and the guide member 5 is in the approximate center of the guide groove hole 6e.

When performing the above-described position adjustment to eliminate such a state, the adjustment screw 7 is loosened with, for example, a screwdriver and the adjustment screw 7 is moved to the right (in the direction of arrow A) as shown in FIG. ) Or leftward (arrow B direction) as shown in FIG. 3C, the guide member 5 is guided to the oval guide groove 6e of the base member 3 accordingly. Therefore, not only the guide member 5 but also the connecting member 4 moves in the right direction and the backward direction (arrow C direction) shown in FIG. Move forward (arrow D direction). Thereby, the guide member 5 can be moved to the approximate center of the guide slot 6e, and the one-sided state of the guide member 5 can be eliminated. After that, when the adjusting screw 7 is screwed and tightened, the connecting member 4 that can be moved freely in the gap 3c of the base member 3 is drawn, and the connecting member 4 and the truncated cone 6a of the base member 3 are pulled together. The base member 3 is fixed by being sandwiched and the guide member 5 is positioned, and the position adjustment for reducing the swinging of the upper suspension door 2 in the front-rear direction is completed. At that time, the protrusion 4 b (see FIG. 2B) provided on the connecting member 4 is in a state of biting into the base member 3.
In FIGS. 3A and 3C, the adjustment screw 7 is moved to the end of the gate slot 6b, and the guide member 5 is moved to the end of the guide slot 6e. However, the position adjustment may be completed by moving the adjustment screw 7 to the midway position of the gate groove 6b (therefore, the guide member 5 is also halfway to the guide groove 6e). Of course.

By the way, the lower guide 1 with the front-rear direction adjustment according to the above-described embodiment is shown in FIG. 4A. The upper suspension door 2 having an open end, that is, the left and right direction of the upper suspension door 2 (arrows). Although the case where it used for the thing which the both ends of the ditch | groove 2a formed in the (A, B direction) opened is demonstrated, as shown to the same figure (B), the upper suspended sliding door by which the mouth end surface is obstruct | occluded It goes without saying that it can also be used for 20.
In this case, it cannot be visually confirmed whether or not the guide member 5 is in contact with the concave groove 20a of the upper suspension door 20, but the upper suspension door 20 is repeatedly opened and closed several times to open and close the upper suspension door 20. If the lightness of the operation is confirmed, the one-side contact state can be grasped. Therefore, if the adjustment screw 7 is moved in the left-right direction according to the operation procedure described in the above embodiment, the swinging in the front-rear direction of the upper sliding door 20 should be reduced. Position adjustment can be performed easily.

  Moreover, in the lower guide 1 with the front-rear direction adjustment according to the above-described embodiment, the adjustment screw 7 has a head shaped like a flat head screw, but for example, the front-rear direction adjustment. It may have a hexagonal shape as shown in the adjusting screw 9 of the subordinate guide 10 (see FIG. 5). If it does in this way, it can adjust with the spanner from the side of the upper sliding door 2, in other words, from the front-back direction. Moreover, also when the adjustment screw 9 is located under the upper suspension door 2, it can adjust with a spanner from the front-back direction.

  The lower suspension guide with the front / rear direction adjustment of the upper sliding door of the present invention is a position adjustment device for reducing the front / rear direction swing of the upper suspension door, so that the device itself can be simplified, that is, the cost can be reduced. Since the height of ground clearance at the part is suppressed, and workability in adjustment is good and work time is not required, it can be said that the utility value is higher than existing ones.
