  By the way, since this kind of upper guide device is provided with a plurality of members such as the sliding door fixing body, the suspension connecting portion, and the runner body as described above, there is a vertical play between these members. There is. The height adjusting mechanism is provided with a relatively large number of parts, and there may be some play between these various parts. Based on these play, the backlash in the vertical direction increases, and in particular, when the runner body is rotatably attached to the suspension connecting portion as in the device described in Patent Document 1, this rotational performance is secured. There is a play to do, and there is a tendency for backlash in the vertical direction to increase.

  These rattlings are desired to be suppressed because they can cause the sliding doors to spring up, specifically noise.

  The present invention has been made in view of the above-described conventional problems, and an object thereof is to provide an upper guide device for an upper suspension type sliding door that can suppress the flipping of the sliding door caused by play in the vertical direction. Yes.

  In order to solve the above problems, an upper guide device for a sliding door according to the present invention includes a sliding door fixing body fixed to an upper portion of a sliding door that opens and closes an opening of a structure, and a suspension connection projecting upward from the sliding door fixing body. And a runner body that guides the sliding door along an upper rail provided in the structure and is attached to the tip of the suspension connecting portion, and is attached to the runner body so as to be vertically movable and the sliding door A pressing member that contacts the top surface of the sliding door, and an inclined hole that is provided in one of the runner body and the pressing member and extends in a vertical direction with respect to an upper edge of the sliding door, and the runner body and the pressing member A slide shaft portion that is provided on the other side and has the same width as that of the inclined hole and that is relatively guided along the inclined hole to move the pressing member up and down in an oblique direction. The It is characterized in that.

  Here, with respect to the pressing member, “being in contact with the top surface of the sliding door” means not only the one that is always in contact with the top surface of the sliding door during the opening / closing operation of the sliding door, but also the sliding door opening / closing operation. Those that abut the top surface are also included. The “top surface of the sliding door” may be not only the top surface of the sliding door itself but also the top surface of a member provided integrally with the top of the sliding door. Further, regarding the slide shaft portion, “having the same width as the inclined hole” means that the slide shaft portion is configured to have substantially the same width in addition to the case where the inclined shaft is configured to have the same width. It is a concept that also includes. In this case, the slide shaft portion can be smoothly moved along the inclined hole by setting it slightly smaller than the width of the inclined hole.

  According to the present invention, the sliding door fixing body, the suspension connecting portion, the runner body, and the pressing member as described above are provided, the inclined hole provided in one of the runner body and the pressing member, the runner body, and the pressing member. Since it has a slide shaft portion that is provided on either one of the members and is relatively guided along the inclined hole, there is play in the mutual attachment of the sliding door fixing body, the suspension connecting portion, and the runner body, Even when the sliding door is about to jump up, the top surface of the sliding door is pressed by the pressing member, so that the sliding door can be effectively prevented from jumping up.

  That is, the pressing member is in contact with the top surface of the sliding door, and is attached to the runner body so as to be movable up and down by the inclined hole and the slide shaft portion. Therefore, the frictional resistance between the inner peripheral surface of the inclined hole and the outer peripheral surface of the slide shaft portion suppresses the relative displacement between the inclined hole and the slide shaft portion, and the pressing member contacts the top surface of the sliding door. The contacted state can be maintained, and the pushing-up of the sliding door can be effectively suppressed by this pressing member. On the other hand, when the relative distance between the sliding door and the runner body changes slowly, for example, when the height of the upper guide device is adjusted, the slide shaft portion moves relatively along the inclined hole. It is possible to maintain a state in which the member is appropriately in contact with the top surface of the sliding door.

  In the present invention, the runner body is fixed with respect to the suspension connection portion, and the specific mounting structure of both is not particularly limited. However, the runner body is connected to the suspension connection portion. Therefore, it can be suitably used for an upper guide device that is rotatably mounted.

  In such a configuration, since the rotation of the runner body with respect to the suspension connecting portion is ensured, there is a possibility that play in the vertical direction becomes relatively large, and the sliding door jumps up significantly. Therefore, by applying to the upper guide device having such a configuration, the effect of suppressing the sliding doors can be maximized.

  In this invention, the pressing member may be urged downward by an elastic body such as a spring or rubber and pressed against the top surface of the sliding door. Therefore, it is preferable to be configured to be movable downward by its own weight.

  If comprised in this way, a number of parts can be reduced and it can comprise simply and cheaply.

  In the present invention, the inclination angle of the inclined hole is not particularly limited, but the inclined hole is preferably inclined within a range of 5 degrees or more and less than 45 degrees with respect to the upper edge of the sliding door. More preferably, the lower limit is set to 7 degrees and the upper limit is set to 30 degrees.

  If comprised in this way, the frictional resistance of an inclined hole and a slide shaft part can be exhibited appropriately, and a press member can be made to contact a sliding door top face reliably at the time of sliding door opening / closing operation.

  In this invention, the inclination direction of the inclined hole is not particularly limited as long as it is inclined in the vertical direction. For example, the inclination hole is configured to be inclined toward the anti-sliding door side toward the suspension connecting portion side. Although it may be a thing, it is preferable that the said inclination hole is comprised so that it may incline to the said sliding door side as it goes to the said connection part for suspension.

  If comprised in this way, since a press member will contact | abut to the position close | similar to the connection part for suspension in the top surface of a sliding door, it can suppress more reliably raising of the sliding door based on the play between each member. it can.

  The specific configuration of the runner body is not particularly limited, and may include a runner body portion and a guide sliding portion such as a guide block attached to the runner body portion and sliding along the upper rail. The runner body preferably includes a guide roller that travels along the upper rail, and a runner main body portion to which the guide roller is attached and the guide roller is attached. Further, the specific configuration of the runner main body is not particularly limited, but the runner main body includes a roller mounting portion to which the guide roller is mounted and a sliding door opening / closing direction with respect to the roller mounting portion. A member mounting portion that is continuously provided and to which the pressing member is mounted; and a jumping suppression projection portion that protrudes upward from the member mounting portion and is made of a hard synthetic resin. It is preferable that the top part abuts against the inner surface of the top wall of the upper rail together with the guide roller set higher than the top part of the roller mounting part.

  According to this structure, when an upward impact force is applied to the upper guide device as the sliding door is flipped up, the guide roller comes into contact with the top wall inner surface of the upper rail together with the jumping suppression protrusion, thereby sliding the door. Can be more effectively suppressed.

  In this case, it is preferable that the slide shaft portion is provided on the member mounting portion, and the jumping suppression protrusion is arranged in parallel with the slide shaft portion in the vertical direction.

  That is, the slide shaft portion is easily subjected to an upward impact force through the pressing member when the sliding door is flipped up, and the jump-up suppressing projection portion is directly above the slide shaft portion (position arranged in the vertical direction). It is possible to more effectively suppress the sliding door from being flipped up.

  In this invention, one of the runner body and the pressing member has a first inclined contact surface along the inclined hole, and the other of the runner body and the pressing member has the first inclined surface. It is preferable to have a second inclined contact surface that contacts the contact surface. The second inclined contact surface need not always be in contact with the first inclined contact surface at all times, and may be at least partially in contact with each other when the sliding door is flipped up.

  With this configuration, when an impact force acts upward, such as when the sliding door is flipped up, in addition to the engagement between the inclined hole (specifically, the peripheral edge thereof) and the slide shaft portion, When the second inclined contact surfaces come into contact with each other and come into surface contact with each other, displacement in the left-right direction can be suppressed, and a reaction force against the impact force can be applied on the spot or in the vicinity thereof. However, the vertical movement of the sliding doors can be suppressed more effectively.

  In the present invention, the specific configuration of the pressing member is not particularly limited. However, the pressing member is disposed between the upper rail and the top surface of the sliding door, and the upper member in a plan view. It is preferable to have a vertical operation piece that protrudes from the rail to at least one of the front and rear.

  If comprised in this way, when operating a press member upward, it can operate easily using the said up-and-down operation piece, without the said upper rail getting in the way. Further, the pressing member can be lowered by its own weight due to the weight of the vertical operation piece.

  According to the upper guide device of the sliding door according to the present invention, even when there is play in the mutual attachment of the sliding door fixing body, the suspension connecting portion, and the runner body, and the sliding door is about to jump up, The top surface is pressed and the sliding door can be effectively prevented from jumping up.

It penetrates in the (front-rear direction). The inclination angle of the inclined guide hole 50a with respect to the upper edge of the sliding door D (which coincides with the horizontal direction in the present embodiment) is specifically set within a range of 5 ° to 45 °. That is, when the inclination angle is smaller than 5 °, the runner body 4 and the pressing member 5 are relatively moved even when a force having a vertical component is applied slowly to either the runner body 4 or the pressing member 5. It becomes difficult to be displaced. When the inclination angle is larger than 45 °, the runner body 4 and the pressing member 5 are relatively moved even when a force having a vertical component is applied suddenly to either the runner body 4 or the pressing member 5. Therefore, the original function of the upper guide device that is difficult to displace with respect to the impact force is deteriorated. This inclination angle is preferably set within a range of 7 ° to 30 °. In the present embodiment, the inclined guide hole 50a is set to have an angle of 10 ° with respect to the sliding door upper edge (horizontal direction in the left-right direction).

  In this embodiment, the inclination direction of the inclined guide hole 50a is set to be inclined downward as it goes to the left in the illustrated example, in other words, the top surface D2 of the door body D1 as it goes toward the connecting shaft 3 side. It is comprised so that it may incline to the side. In addition, the inclined guide hole 50a has an elongated oval shape when viewed from the front, and is set to have a width (a direction perpendicular to the center line) that matches the outer diameter of the slide boss portion 79. Further, the inner peripheral surface of the inclined guide hole 50 a is configured by a surface parallel to the longitudinal axis, and is configured to generate a predetermined frictional force with the slide boss portion 79. Further, the height dimension between the upper end and the lower end of the inclined guide hole 50a is set to be larger than at least the height that can be adjusted by the height adjusting screw 21, and is specifically set in the range of 3 mm to 15 mm. Yes.

  Moreover, the lower surface of this slide fitting part 50 is comprised as a smooth surface which has a normal line in an up-down direction, and shall overlap with the top surface D2 of the door main body D1. That is, the lower surface of the slide fitting portion 50 is configured to be able to contact the top surface D2. On the other hand, the upper surface of the slide fitting portion 50 constitutes an upper inclined guide surface 50b (corresponding to the first first inclined contact surface) having an inclination coinciding with the inclination angle of the inclined guide hole 50a. On the other hand, when an upward impact force is applied, the upper inclined guide surface 50b comes into contact with the inclined inner surface 78c of the movement allowance groove 78b of the runner body 4, and a frictional force is generated even with this contact. Has been made.

  As described above, the auxiliary guide portion 51 is provided at the lower right end portion of the slide fitting portion 50 so as to protrude in the front-rear direction. The auxiliary guide portion 51 has a substantially right triangle shape when viewed from the front, and the lower end edge and the one side edge (the right side edge in the illustrated example) coincide with the lower end edge and the one side edge of the slide fitting portion 50, respectively. The slide fitting portion 50 is integrally formed. The upper surface of the auxiliary guide portion 51, like the upper inclined guide surface 50b of the slide fitting portion 50, has a lower inclined guide surface 51a (second first inclined contact) having an inclination that matches the inclination angle of the inclined guide hole 50a. Corresponding to the surface). Similarly to the upper inclined guide surface 50b, the lower inclined guide surface 51a is also used as a runner side inclined guide of the runner body 4 when an upward impact force is applied to the pressing member 5. The surface 78e is surely brought into contact with the surface 78e, and a frictional force accompanying the contact is generated.

  The width of the lower inclined guide surface 51a is relative to the plate thickness of the slide fitting portion 50 from the viewpoint of generating an appropriate frictional force while ensuring the slidability between the runner body 4 and the pressing member 5. It is preferably set within a range of 0.3 times to 1.0 times, and more preferably set within a range of 0.5 times to 0.7 times.

  Next, the operation piece 52 will be described. The operation piece 52 has a substantially inverted T shape when viewed from the side, and is operated when the pressing member 5 is manually moved up and down. In the present embodiment, the pressing member 5 moves downward due to its own weight. It also plays a role as a weight.

  Specifically, the operation piece 52 includes a base block 52a disposed at a central portion in the front-rear direction, and an operation flange portion 52b provided at the lower end portion of the base block 52a so as to protrude in the front-rear direction. 52b can be manually operated.

  The base block 52 a is configured to be thicker in the front-rear direction than the slide fitting portion 50, and the upper surface is provided continuously with the upper inclined guide surface 50 b of the slide fitting portion 50. For this reason, the upper surface of the base block 52a is inclined up and down in the left-right direction, and the inclination angle coincides with the inclined guide hole 50a. The thickness of the base block 52a is set in the range of 1.2 to 3.0 times the thickness of the slide fitting portion 50.

  The operation flange portion 52b is configured as a plate-like body extending in the front-rear direction, and a plurality of groove portions 52c along the vertical direction are provided on the distal end surface, thereby serving as a slip stopper. As shown in FIG. 5B, the distal end of the operation flange portion 52b is set so as to protrude from the upper rail L in a plan view so that it can be easily operated. In other words, the distance from the front-rear center of the tip of the operation flange portion 52b is set to be longer than the distance from the front-rear center of the upper rail L to the outer surface of the side wall portion L2.

  Such a pressing member 5 is assembled to the member mounting portion 72 of the runner body 4 as follows, for example.

  That is, the slide fitting portion 50 of the pressing member 5 is inserted into the movement allowable groove 78b of the member mounting portion 72 from the upper end portion, and the upper inclined guide surface 50b of the slide fitting portion 50 is connected to the inclined inner surface 78c of the movement allowable groove 78b. Abut. And it aligns so that the inclination guide hole 50a of this slide fitting part 50 may overlap with the boss hole 78f of the member attaching part 72 in front view. In this state, the slide boss portion 79 is inserted into the boss hole 78f and the inclined guide hole 50a, and the slide boss portion 79 is caulked from both the front and rear sides to fix the slide boss portion 79 to the holding portion 78 of the member mounting portion 72.

  Thereby, the pressing member 5 is attached to the runner body 4.

  In this state, the pressing member 5 is held with respect to the runner body 4 so as to be able to move up and down in an oblique direction, and moves downward due to its own weight including the operation piece 52.

  Further, in this state, the upper inclined guide surface 50b and the lower inclined guide surface 51a of the pressing member 5 abut or substantially abut on the inclined inner surface 78c and the runner side inclined guide surface 78e of the holding portion 78 of the member mounting portion 72, respectively. When the external force is applied at least in the direction in which the runner body 4 and the pressing member 5 approach each other, they are in contact with each other.

  That is, in the present embodiment, the upper inclined guide surface 50b and the lower inclined guide surface 51a of the pressing member 5 correspond to the “first inclined contact surface” (or second inclined contact surface) referred to in the present invention. In the runner body 4, the inclined inner surface 78c and the runner side inclined guide surface 78e correspond to the “second inclined guide surface” (second inclined contact surface) according to the present invention. In other words, in the upper guide device 1 of the present embodiment, there are a plurality of inclined contact surfaces on each of the runner body 4 and the pressing member 5, thereby causing the vertical impact force to act on both 4 and 5. The inclined contact surfaces are in contact with each other, and a sufficient frictional force is applied.

  Then, by fixing the upper guide device 1 assembled in this way to the door body D1 of the sliding door D, the upper guide device 1 can be installed.

  The operation of the upper guide device 1 configured as described above will be described with reference to FIGS. 1, 6, and 7. 6 and 7 are cross-sectional views showing the upper guide device showing the upper rail in a cross-sectional state. FIG. 6 shows a state in which the pressing member is in contact with the top surface of the sliding door, and FIG. A separated state is shown.

  When the sliding door D shown in FIG. 1 is slid in the opening / closing direction, the sliding door D rolls on the upper rail L of the guide roller 6 of the upper guide device 1, 1 </ b> A, specifically on the front and rear flange portion L <b> 3. D is guided by the upper rail L.

  At this time, the lower surface of the pressing member 5 is in contact with the top surface D2 of the door body D1. Even if the lower surface of the pressing member 5 is separated from the top surface D2, the pressing member 5 is lowered by its own weight due to the sliding door opening / closing operation, and the lower surface of the pressing member 5 comes into contact with the top surface D2. Transition to the state.

  By the way, since there is a play in the mutual attachment of the sliding door fixing body 2, the suspension connecting shaft 3, the runner body 4 and the like, such as the suspension structure of the sliding door D, with the opening / closing operation of the sliding door D, When the sliding door D collides with the door frame, the sliding door D tries to jump up.

  However, the upper guide device 1 of the present embodiment can effectively suppress the jumping of the sliding door D by the pressing member 5 pressing the top surface D2 of the sliding door D.

  That is, when the sliding door D tries to jump up, the sliding door D rises, and the guide roller 6 and the jumping suppression protrusion 73 of the runner body 4 come into contact with the inner surface of the top wall L1 of the upper rail L and are bent downward. Power is generated. As described above, in the upper guide device 1 of the present embodiment, the jumping suppression protrusion 73 is brought into contact with the top wall portion L1 together with the guide roller 6, so that a downward reaction force can be generated in a stable state.

  At the same time, the inclined guide surfaces 50b and 51a on the upper and lower sides of the pressing member 5 are brought into contact with the inclined inner surface 78c and the runner side inclined guide surface 78e of the runner body 4, and frictional forces are generated on the contact surfaces. A downward reaction force is also generated through the contact surface.

  Furthermore, in the upper guide device 1 of the present embodiment, the jumping suppression protrusion 73 is juxtaposed in the vertical direction with the slide boss 79, so that a reaction force can be applied more directly, and the sliding door D Jumping up can be more effectively suppressed.

  Here, although the pressing member 5 is attached to the runner body 4 so as to be movable obliquely in the vertical direction, it has the same width as the inclined guide hole 50a of the pressing member 5, and along the inclined guide hole 50a. The slide boss 79 of the runner body 4 that is relatively guided is inserted into the inclined guide hole 50a, and the inclination angle of the inclined guide hole 50a is set to 10 °. With respect to the force, the tilt guide is caused by the frictional resistance force between the inner peripheral surface of the inclined guide hole 50a and the outer peripheral surface of the slide boss 79 and the mutual frictional resistance force of the inclined contact surfaces 50b, 51a, 78c, 78e. The relative displacement between the hole 50a and the slide boss portion 79 is suppressed, and the pressing member 5 can be kept in contact with the top surface D2 of the sliding door D, whereby the reaction force is effective through the pressing member 5. In It can act on the door D. Moreover, since the inclination angle of the inclined guide hole 50a is set to 10 °, the frictional resistance force between the inclined guide hole 50a and the slide boss portion 79 can be properly exhibited, and more effectively against the sliding door D. Reaction force can be applied.

  That is, since the pressing member 5 is in contact with the top surface D2 of the door body D1 of the sliding door D, even when there is play between the members 2 to 4, the reaction force is directly applied to the sliding door D through the pressing member 5. Can be transmitted, and the jumping of the sliding door D can be effectively suppressed. Moreover, in the upper guide device 1 of this embodiment, the inclined guide hole 50a is configured to be inclined toward the top surface D2 side of the sliding door D as it goes toward the suspension connecting shaft 3 side. At the position, the pressing member 5 comes into contact with the top surface D2 at a position close to the suspension connection shaft 3 as compared with the case where the inclination direction of the inclination guide hole 50a is reversed. The jumping up of the sliding door D based on the play can be effectively suppressed.

  On the other hand, when the relative distance between the sliding door D and the runner body 4 is changed, for example, when the height of the upper guide device 1 is adjusted, first, as shown in FIG. Move diagonally upward. That is, when the operation piece 52 is lifted upward, the pressing member 5 can be relatively displaced obliquely upward by the slide boss portion 79 along the inclined guide hole 50a. In this state, the relative distance between the sliding door D and the runner body 4 can be changed by rotating the height adjusting screw 21.

  If the relative distance between the sliding door D and the runner body 4 by the height adjusting screw 21 is changed without moving the pressing member 5 in advance with this change, the pressing member 5 follows this change. And the relative position of the runner body 4 can be changed.

  In addition, the upper guide apparatus 1 of the sliding door demonstrated above is one Embodiment of this invention, About the specific structure etc., it can change suitably in the range which does not deviate from the meaning of this invention. Hereinafter, the modification is demonstrated.

  (1) In the above embodiment, the upper guide device 1 in which the pressing member 5 is provided with the inclined guide hole 50a and the runner body 4 is provided with the slide boss portion 79 has been described. However, the inclined hole such as the inclined guide hole is provided in the runner. A guide part such as a slide boss part may be provided on the pressing member.

  (2) In the above-described embodiment, the inclination direction of the inclined guide hole 50a has been described as being inclined toward the sliding door D side (lower side) toward the suspension connecting shaft 3 side. That is, you may incline in the opposite side (upper side) to the sliding door D side as it goes to the suspension connection shaft 3 side.

  However, jumping up the sliding door D can be more appropriately suppressed by configuring as in the above embodiment.

  (3) In the above-described embodiment, the pressing member 5 has been described so as to be movable downward by its own weight. For example, the pressing member is biased by an elastic body, and includes a downward direction and an inclined hole. It may be urged in the direction in which the force of the above acts. For example, when a helical spring is adopted as the biasing means, a helical spring is interposed between the runner body and the pressing member, and the pressing member is attached along the inclination direction of the inclined hole by the helical spring. It may be something that makes it stand. However, when the urging member is provided in this way, not only the number of parts but also the manufacturing process is increased and the cost becomes relatively high, so that the pressing member can be moved downward by its own weight as in the above embodiment. Preferably it is comprised.

  (4) In the embodiment, the upper rail L is configured in a C-shape that opens downward, but the specific shape of the upper rail L is not limited to this. For example, the front and rear flange portion L3 is configured in a flat plate shape, but may be configured in an arc shape protruding downward. Moreover, although the upper rail L is comprised in C shape, it may be comprised in U shape, ie, it opens so that it may open to the side. In this case, the runner body guide roller is configured as a single wheel.

  (5) In the embodiment, the runner body 4 is rotatably attached to the suspension connection shaft 3, but the runner body 4 may be fixed to the connection shaft 3.

  (6) In the above embodiment, the pressing member 5 is provided with the operation piece 52. However, the specific configuration of the upper and lower operation pieces is not particularly limited, and may be omitted as appropriate. it can.

  However, in the plan view, if a vertical operation piece that protrudes forward and backward from the upper rail L is provided as in the present embodiment, the upper rail L does not get in the way when the pressing member 5 is operated upward. The operation piece 52 can be used for easy operation. Moreover, it can be set as the structure which the press member 5 descend | falls with dead weight with the weight by this up-and-down operation piece 52, and the operation piece 52 can be made to play another role.
