  By the way, in the sliding door device with the door body full open holding device shown in the above-mentioned Patent Document 1, as described above, the locking member to be locked to the locked member is formed by bending the leaf spring. The elastic force which a leaf | plate spring has by use of a period fell, and there existed a possibility that the fully open holding performance of a door body might fall. Moreover, in the sliding door apparatus shown by the said patent document 1, since the to-be-latched member latched by this latching member other than the latching member of a door body full open holding | maintenance apparatus is needed, the sliding door apparatus whole The structure was complicated.

  For this reason, the door body fully open holding performance is further improved, and the appearance of a door body fully open holding device with a simplified structure has been desired.

  An object of the present invention is to provide a sliding door device with a door body fully open holding device, which can improve the fully open holding performance of the door body, and includes a door body fully open holding device capable of simplifying the structure. By the way.

  A sliding door device with a door body fully open holding device according to the present invention includes a door body that opens and closes an opening, a guide member that guides the opening and closing movement of the door body, the door body is held in a fully opened state, and the door body and Of the non-moving members that face the opening side end of the door body and are stationary with respect to the door body, the door body fully-open holding device having a magnet member disposed on one side, and the magnet on the other side The magnetic member is disposed at a position facing the member and is attracted to the magnet member.

  In the present invention, the door body fully opening holding device is disposed on one of the door body and the immovable member that is opposed to the door body and on the opening side of the door body and is stationary with respect to the door body. A magnetic member that has a magnet member and is attracted to the magnet member is disposed at a position facing the magnet member on the other side.

  For this reason, in the present invention, the fully opened state of the door body is held by the magnet member disposed on one of the door body and the stationary member being attracted by the magnetic member disposed on the other side. It has become.

  That is, in the present invention, the fully opened state of the door body is maintained by the locking member formed by bending the leaf spring being locked to the locked member by the small-diameter roller as in the conventional example described above. Instead, the magnetic member is held by being attracted to the magnet member.

  For this reason, according to this invention, a possibility that the fall of the fully open holding | maintenance performance of a door body by long-term use of a door body fully open holding | maintenance apparatus will become smaller. That is, according to the present invention, the fully open holding performance of the door can be further improved.

  Further, in the present invention, since the fully open state of the door body is held by the magnetic member adsorbing to the magnet member of the door body fully open holding device, the structure of the door body fully open holding device can be simplified. As a result, the structure of the entire sliding door device can be simplified.

  Thus, according to the present invention, compared with the conventional sliding door device with a door body fully open holding device, the door body fully open holding performance can be improved and the structure can be simplified.

  In addition, since there is “a magnet member disposed on one of the door body and an immovable member that is opposed to the door body and is stationary with respect to the door body”, the magnet The member is disposed on one of the door body and the stationary member. In addition, since there is “a magnetic member that is disposed at a position facing the magnet member on the other side and is attracted to the magnet member”, the magnetic member that is attracted to the magnet member is disposed on the other of the door body and the stationary member. Is. That is, when the magnet member is disposed on the door body, the magnetic member is disposed on the stationary member. When the magnet member is disposed on the stationary member, the magnetic member is disposed on the door body. It is.

  In the present invention, the magnet member is arbitrary as long as it can generate a magnetic field and can attract the magnetic member. For example, the magnet member may be a permanent magnet, or may be an electromagnet as long as power can be constantly supplied. When the magnet member is a permanent magnet, the type of the permanent magnet is arbitrary. For example, it may be a ferrite magnet, a neodymium magnet, a KS steel, an MK steel, an alnico magnet, or a samarium. A cobalt magnet or the like may be used.

  In the present invention, the magnetic member is arbitrary as long as it is a member (magnetic body) that can be attracted to the magnet member, and may be iron, chromium, cobalt, ferrite, or the like.

  In the present invention, the magnet member may be directly attached to one of the door body and the stationary member, or may be attached to one of the door body and the stationary member via the attachment member.

  In the latter case, the type and structure of the mounting member are arbitrary, and as an example, a base portion that is attached to one of the door body and the stationary member, and a base member that is spaced apart from the base portion in the opening / closing movement direction of the door body. And a holding part that holds the magnet member, and an elastic deformation part that connects the holding part and the base part and is elastically deformable in the opening / closing movement direction of the door body. be able to.

  According to this, when the magnetic member is attracted to the magnet member, the impact force received by the magnetic member from the magnet member becomes smaller due to the elastic deformation of the elastic deformation portion of the mounting member.

  The type and structure of the elastic deformation portion of the mounting member are arbitrary as long as the base portion of the mounting member and the holding portion are connected to each other and can be elastically deformed. For example, both end portions of the holding portion And an elastic member that connects both ends of the base portion.

  Here, the type and structure of the elastic member forming the elastically deformable portion is arbitrary, and may be, for example, soft rubber, a coil spring may be a direction in which the direction of the shaft core is opened and closed, and a leaf spring may be used. Further, a porous body such as a sponge may be used.

  In the present invention, when the elastic member forming the elastic deformation portion is made of soft rubber, the base portion of the attachment member is made of hard rubber, the holding portion of the attachment member is made of soft rubber, and the attachment member is an integrally molded product. (For example, by extrusion molding or pultrusion molding).

  According to this, the manufacturing process of the mounting member can be simplified and the manufacturing cost can be reduced.

  Note that, regardless of whether or not the mounting member is an integrally molded product, the material of the holding portion and the base portion of the mounting member is arbitrary. For example, the above-described soft rubber or hard rubber, metal, or synthetic resin may be used. Ceramics, wood, or a composite material thereof may be used.

  In the present invention, the soft rubber or hard rubber may be, for example, synthetic rubber, natural rubber, silicon rubber, urethane rubber, fluoro rubber, or the like.

  In the present invention described above, it is preferable that the holding portion of the mounting member covers at least the surface of the magnet member that faces the other of the door body and the immobile member.

  According to this, it is possible to prevent the magnet member from being in direct contact with the other of the door body and the stationary member and being damaged.

  In order for the holding part to hold the magnet member more securely, it is more preferable that the holding part has a structure for storing the magnet member.

  In the present invention described above, the magnetic member is “arranged at a position facing the magnet member on the other side”, so that the magnetic member is located at a position facing the magnet member on the other of the door body and the stationary member. It may be attached, or the other of the door body and the stationary member may be formed of a magnetic member. In the former case, the magnetic member may be directly attached to the other of the door body and the stationary member, or may be attached to the other of the door body and the stationary member via the attachment member. Good. In the latter case, the other of the door body and the stationary member may be formed of a magnetic member, and only the portion of the other of the door body and the stationary member that faces the magnet member It may be formed of a magnetic member.

  In the present invention described above, the stationary member may or may not be disposed on the stationary member so that the end of the door on the opening side contacts when the door is opened.

  In the former case, it is preferable that the thickness dimension, which is the dimension in the opening / closing movement direction of the door body of the mounting member before the magnetic member is attracted to the magnet member, is larger than the thickness dimension of the door-contacting member.

  According to this, when the door body is opened and moved, the magnetic member is first attracted to the magnet member, and then the elastic deformation portion of the mounting member is elastically deformed. As a result, the thickness dimension of the mounting member gradually decreases, and when this thickness dimension is the same as the thickness dimension of the door stop member, the opening side end of the door body comes into contact with the door stop member. Become. That is, when the door body is opened and moved, the opening side end of the door body comes into contact with the door stop member because the elastic deformation portion of the attachment member is elastically deformed, and the thickness dimension of the attachment member is It is when it becomes the same as the thickness dimension of a member.

  Therefore, the impact force received when the end of the door on the opening side comes into contact with the door stop member is further reduced by the elastic deformation of the elastic deformation portion of the mounting member.

  In the present invention described above, when the mounting member is a hollow member opened at both ends in a direction orthogonal to or substantially orthogonal to the opening / closing movement direction of the door body, the base portion has both ends opened by the mounting member. A fixing member that is inserted from each of the above, and that has a support portion that supports the surface of the base portion facing the holding portion, and a fixing portion that is fixed to one of the door body and the stationary member with a fastening member. It may be fixed.

  Here, it is preferable that a recess portion that is recessed toward the one side is formed on the surface of the base portion that faces the holding portion, and the support portion of the fixing member can be immersed in the recess portion.

  According to this, even if the elastically deforming portion of the mounting member is largely elastically deformed, it is possible to prevent the holding portion of the mounting member from contacting (interfering) with the support portion of the fixing member. Thereby, it is prevented that a holding | maintenance part and an elastic deformation part are damaged by contact | abutting to a support part.

  Moreover, in this invention, you may make it the base part of an attachment member be fixed to one of a door body and a stationary member with a fixing tool. In this case, it is preferable that a recessed portion that is recessed toward one side is formed on the surface of the base portion that faces the holding portion, and that the fastening device can be immersed in the recessed portion.

  According to this, even if the elastically deforming portion of the mounting member is greatly elastically deformed, the holding portion of the mounting member is prevented from coming into contact (interference) with the fastening device. Thereby, it is prevented that a holding | maintenance part and an elastic deformation part are damaged by contact | abutting to a fastening tool.

  The sliding door device with a door body fully opening holding device according to the present invention may or may not include a door body housing portion for housing the door body that has been opened and moved.

  As an example of the arrangement of the magnet member and the magnetic member in the former case, the magnet member is an eaves frame member (in other words, on the door end side of the door body, facing the opening side end of the door body inside the door body housing portion. (The frame member) and the end of the door on the opening side are arranged, and the magnetic member can be arranged on the other side.

  In the above-mentioned present invention, the door body automatic closing means for giving the door body a moving force toward the closing side may or may not be provided.

  Here, the form and structure of the door body automatic closing means are arbitrary. As an example, the door body automatic closing means is provided in the vicinity of the closing side end portion of the opening portion in the immovable member which is stationary with respect to the door body. There may be mentioned a spiral spring mechanism and a structure including one end connected to the spiral spring mechanism and the other end connected to a door member. According to this, by opening and moving the door body, the spring force is accumulated in the spiral spring of the spiral spring mechanism by the string-like member drawn out from the spiral spring mechanism. And, when the operation force to the closing side acts on the door body in which the fully opened state is held, when the adsorption of the magnet member and the magnetic member is released, the door body that has reached the fully opened position is It is automatically closed and moved by the spring force accumulated by the opening movement. When the door body has reached the fully open position, the magnetic force of the magnet member (more precisely, the magnetic force for holding the door body in the fully open state) is the spring force (exactly stored in the spiral spring of the spiral spring mechanism). Is required to be larger than the spring force for closing and moving the door body.

  Further, as another example of the door body automatic closing means, a guide member that guides the opening / closing movement of the door body is arranged so as to be inclined obliquely downward toward the closing side of the door body. According to this, the door body that has reached the fully open position when the magnet member and the magnetic member are released from each other due to the operating force acting on the closing side acting on the door body that is kept fully open. Is automatically closed and moved while being guided by the inclined guide member due to its own weight. When the door body has reached the fully open position, the magnetic force of the magnet member (more precisely, the magnetic force for holding the door body in the fully opened state) is the weight of the door body (more precisely, the weight of the door body). Of these, it is necessary to be larger than the closing movement direction (obliquely downward component) of the door body.

  As described above, in the present invention, when the door body is provided with the door body automatic closing means for applying the moving force to the closing side, when the door body has reached the fully opened position, the door body is held in the fully opened state. Therefore, it is necessary that the magnetic force for this is larger than the force for closing the door body by the door body automatic closing means.

  In the present invention described above, when the operation force toward the closing side acts on the door body that is kept in the fully open state, when the adsorption between the magnet member and the magnetic member is released, the door body An urging means for applying an urging force toward the closing side may be provided.

  According to this, compared with the case where the urging means is not provided, the operator can close and move the door body with a lighter operating force, and the initial closing movement speed of the door body is faster. It can be. Thereby, the time required for the door body to reach the fully closed position from the fully open position can be shortened.

  Here, the form and structure of the urging means are arbitrary, but as an example, a rotation member that can rotate around a rotation center axis whose axial direction is the vertical direction of the door body, and the rotation center. A holding member that holds the shaft, the holding member being fixed to the stationary member that is stationary with respect to the door body, and the rotating member extending in a horizontal direction from the base. A horizontal extending portion to which the rotating member is attached, the rotating member being able to contact an end portion of the door body on the opening side, and the rotating member and the rotating member at the holding member Examples of the member closer to the closing side of the door body than the rotation center axis of the member include those connected by an elastic member.

  According to this, when the door body is opened and moved to the fully open position, the magnetic member is attracted to the magnet member, and the end of the door body on the closed side comes into contact with the rotation member. Rotate to the opening side of the door body around the center. As a result, the elastic member that connects the rotating member and the portion of the holding member closer to the closing side of the rotating member than the central axis of rotation of the rotating member extends, so that elastic force is accumulated in the elastic member. It will be done. When the door body is opened and moved to the fully open position, the magnetic member is attracted to the magnet member, and the elastic force to be contracted is accumulated in the elastic member.

  When the operation force toward the closing side acts on the door body in which the fully opened state is held, the state where the magnetic member is attracted to the magnet member is released, the rotating member becomes the elastic member. It is turned to the closing side of the door body by the elastic force accumulated in the door. Thereby, the door body which the rotation member contacted receives the external force to the closing side. That is, since the biasing force to the closing side is applied to the door body, the operator can close and move the door body with a lighter operating force, and the door body can be moved more quickly at the initial closing speed. Can be obtained.

  In the example of the urging means described above, the type and structure of the elastic member for connecting the rotating member and the holding member are arbitrary, and for example, a coil spring or string-like rubber may be used.

  The present invention described above can be applied to any sliding door device. For example, the present invention includes an engaging portion provided on the door body and movably engaged with the guide member, and an attachment member for attaching the engaging portion to the door body. A sliding door device that is disposed above the door body, the engaging portion is provided on an upper portion of the door body, and the door body is a top-suspended door body suspended from the guide member by the engaging portion; That is, the present invention can be applied to an upward sliding type sliding door device, and can be applied to a normal sliding door device or the like in which the opening / closing movement of the door body is guided by the upper and lower guide members.

  In the present invention described above, the number of door bodies may be one or more. When there are a plurality of door bodies, these door bodies may be of a single-draw type, or a draw-type one (for example, an opening that is opened and closed by a pair of left and right door bodies) , Or the like in which the opening is opened and closed by two sets of first and second door bodies on the left and right sides).

  In the present invention described above, the opening / closing movement direction of the door body may be a linear direction, a curved direction, or a combination of these directions.

  In the present invention described above, the type and structure of the guide member for guiding the opening / closing movement of the door body are arbitrary, and for example, a guide rail or a slide rail (sliding rail) may be used.

  In the present invention described above, the type and structure of the engaging portion that is movably engaged with the guide member are also arbitrary. However, when the guide member is the guide rail, the engaging portion is attached to the guide rail. When the guide member is the slide rail, the engaging portion is a slide portion that is slidably engaged with the slide rail.

  According to the present invention, it is possible to improve the fully open holding performance of the door body and to obtain an effect that the structure can be simplified.

The inspection cover 31 is formed obliquely downward at the upper end, and is engaged with an engaging portion 31A that is engaged with the inclined extending portion 10G of the upper frame member 10, and extends vertically or substantially vertically downward from the engaging portion 31A. It has a front part 31B, a lower surface part 31C that is bent horizontally or substantially horizontally from the lower end of the front part 31B to the inside of the upper frame member 10, and an upright part 31D that rises from the tip of the lower surface part 31C. The locking portion 31A, the lower surface portion 31C, and the upright portion 31D ensure the overall rigidity of the inspection cover 31 formed by bending the sheet metal. Although not shown, the upright portion 31D is not provided over the entire length in the longitudinal direction of the inspection cover 31 that is the left-right direction of FIG. Is provided with a rising portion deficient portion where the rising portion 31D does not exist at both ends in the longitudinal direction.

  As shown in FIG. 4, the inspection cover 31 when the opening 10 </ b> H is closed has the locking portion 31 </ b> A locked to the inclined extending portion 10 </ b> G of the upper frame member 10, thereby the inspection cover 31. Is supported by the upper frame member 10. Further, as shown in FIG. 1, the lower surface portion 31 </ b> C is a bracket attached to the door frame side frame member 11 and the frame member 13, and both end portions in the longitudinal direction of the inspection cover 31. Are fixed to brackets 32 and 33 provided at positions corresponding to the screw members 34 and 35.

  In addition, when the inspection cover 31 is removed and the opening 10H of the upper frame member 10 is opened in order to perform the work such as the inspection of the door body moving mechanism described above, the screw members 34 and 35 are removed. Since the cover 31 can swing in the inner and outer directions of the upper frame member 10 about the upper locking portion 31A, the cover 31 can be swung in the outer direction of the upper frame member 10 to move the locking portion 31A to the upper frame member. 10 is extracted from the inclined extending portion 10G. When removing the inspection cover 31 in this way, the inspection cover 31 is provided with the above-described missing upper portion not shown in the figure, in which the upper portion 31D does not exist, at both ends in the longitudinal direction of the inspection cover 31. In other words, the position of the tip of the lower surface portion 31C corresponding to the position where the screw members 34 and 35 are arranged is an upright missing portion where the upright portion 31D does not exist. This can be done without interference between the brackets 32 and 33 and the upright portion 31D.

  Further, since the screw members 34 and 35 are inserted into the lower surface portion 31C of the inspection cover 31 and the brackets 32 and 33 from the bottom up, an operator can attach and remove the inspection cover 31. The work to be performed on the screw members 34 and 35 can be performed by the worker standing at the entrance / exit 2 extending his hand up, and this work can be easily performed.

  Furthermore, even if the screw members 34 and 35 are dropped for some reason, the locking portion 31A at the upper end of the inspection cover 31 is locked to the inclined extending portion 10G of the upper frame member 10, and the inspection is performed. Since the brackets 32 and 33 for screwing the male screw shaft portions of the screw members 34 and 35 are present on the upper side of the lower surface portion 31C of the cover 31, the inspection cover 31 is detached from the upper frame member 10 due to vertical vibration or the like. This can be effectively prevented.

  Further, in the present embodiment, as shown in FIG. 4, the locking portion 31 </ b> A of the inspection cover 31 is in direct contact with the inclined extending portion 10 </ b> G on the inclined extending portion 10 </ b> G of the upper frame member 10. A crown member 40 made of rubber, synthetic resin, or the like is covered, so that the upper frame member 10 and the metal that is the material of the inspection cover 31 are in direct contact with each other, and the inspection cover 31 is attached or removed. And the like, and the upper frame member 10 and / or the inspection cover 31 are prevented from being damaged.

  Further, as shown in FIG. 4, for example, a hat-shaped cross section is formed in the longitudinal direction of the inspection cover 31 on the back surface of the front portion 31B of the inspection cover 31 (the inner surface of the upper frame member 10 in the front portion 31B). The reinforcing member 41 that is continuous with the front portion 31B is coupled with a bonding tool such as an adhesive or an adhesive tape, thereby reinforcing the strength of the front portion 31B. Even if the vertical and horizontal dimensions of the front portion 31B are large, the front portion 31B may be prevented from being bent or deformed.

  Next, the aforementioned door body moving mechanism housed and arranged in the internal space of the upper frame member 10 will be described. 5 and 6 are enlarged front views of the door body moving mechanism shown with the inspection cover 31 removed, and FIG. 5 shows the door when the door body 1 reaches the fully closed position which is the closing movement limit. FIG. 6 is an enlarged front view of the body moving mechanism.

FIG.

  As described above, inside the upper frame member 10 having a length extending from the door frame side frame member 11 to the door bottom side frame member 12, the length of the upper frame member 10 extends over substantially the entire length. As shown in FIG. 4, the guide rail 45, which is a guide member that guides the linear opening / closing movement of the door body 1, has a base end portion 45 </ b> A that extends vertically. The base end portion 45 </ b> A is coupled to the hanging portion 10 </ b> B of the upper frame member 10 by a coupling tool 46 such as a screw. On the door body 1, a roller 47, which is an engaging portion that is rotatably engaged with the guide rail 45, is provided above the door body 1, and an attachment member for attaching the roller 47 to the door body 1. As shown in FIGS. 5 and 6, two rollers 47 are provided in the opening / closing movement direction of the door body 1, which is the longitudinal direction of the upper frame member 10. Yes. For this reason, the upper suspension type sliding door device according to the present embodiment is an upper suspension type sliding door device in which the door body 1 is suspended from the guide rail 45 by the two rollers 47.

  Further, a spiral spring type automatic door closing device 50 that is a door automatic closing means for applying a moving force toward the closing side to the door 1 is disposed in the inner space of the upper frame member 10. The automatic body closing device 50 is disposed in the vicinity of the frame member 11 on the door end side of the upper frame member 10, and a coupling tool such as a screw is attached to the hanging portion 10 </ b> B of the upper frame member 10 and the base end portion 45 </ b> A of the guide rail 45. It is combined with. A string-like member 51 made of synthetic resin or the like having one end connected to a spiral spring mechanism (not shown) provided inside the door-body automatic closing device 50 is led out from the door-body automatic closing device 50. The other end of the member 51 is connected to a bracket 48 </ b> A that rotatably supports a door-side roller 47 </ b> A of the two rollers 47. When the front end of the door body 1 that is the end portion of the door body 1 is in contact with the frame member 11 on the door edge side, and the door body 1 fully closes the entrance 2 as shown in FIG. When the door body 1 is opened and moved by a hand holding the grip portion 52 shown in FIG. 2, spring force is accumulated in the spiral spring of the spiral spring mechanism by the string-like member 51 fed out from the door body automatic closing device 50. The door body 1 opened and moved to the fully open position is held in a fully opened state by a door body fully open holding device 70 whose specific structure and operation will be described later. When the fully open state of the door body 1 is released by the operation force to the closing side being applied by the hand holding the grip portion 52 to the door body 1 that is maintained in the fully open state, The door body 1 automatically closes and moves to the fully closed position by the spring force accumulated in the spring. For this reason, the upper suspension type sliding door device according to the present embodiment is an automatic closing type upper suspension type sliding door device.

  As shown in FIG. 1, the position corresponding to the arrangement position of the eaves frame member 13 in the moving path in which the door body 1 opens and closes, in other words, the eaves frame member 11 on the door end side in the baseboard 14 described above. A guide roller 59 is disposed at the end on the side. As shown in FIG. 4, the guide roller 59 is inserted into the lower end portion of the door body 1 that opens downward, and the opening and closing movement guided by the guide rail 45 of the door body 1 This is performed while the lower end of the body 1 is guided by the guide roller 59.

  Also, as shown in FIGS. 5 and 6, in the inner space of the upper frame member 10, a cylinder-type braking device 53 is disposed with the piston rod 53 </ b> A facing the side of the door frame member 12 on the door bottom side, The braking device 53 is attached to the base end portion 45 </ b> A of the guide rail 45 with a bracket 54. Of the two rollers 47 of the door body 1, the bracket 48 </ b> B that rotatably holds the door-side roller 47 </ b> B is opposed to the tip of the piston rod 53 </ b> A facing the opening / closing movement direction of the door body 1. A contact member 55 is attached, and one of the tip portions of the piston rod 53A and the contact member 55 (the tip portion of the piston rod 53A in FIG. 5) can be brought into contact with and separated from the other by an adsorption force or the like. A contact / separation member 56 made of a magnet or the like is provided.

  When the door 1 that has reached the fully closed position is opened and moved as described above, the piston rod 53A whose tip is connected to the contact member 55 by the adsorption force of the contact / separation member 56 extends. When the door body 1 opens and moves beyond the limit of the extension operation of the piston rod 53A, the contact member 55 is separated from the piston rod 53A in the contact / separation member 56. Further, when the door body 1 is closed and moved, the contact member 55 comes into contact with the tip of the piston rod 53A via the contact / separation member 56, and the door body 1 continues to close and move, whereby the piston rod 53A. Since the brake body 53 is provided with a valve that discharges the air inside the cylinder-type brake device 53 while being throttled, the door body 1 is controlled by the throttle action of this valve. While receiving power, the door automatic closing device 50 automatically moves to a fully closed position at a low speed.

  Since the valve is of a type that allows the air to flow into the cylinder-type braking device 53 without restricting the air when the piston rod 53A is extended and operated, the opening movement of the door body 1 from the fully closed position is prevented. This can be done with a small force that causes the spring force of the spiral spring mechanism of the door body automatic closing device 50 to accumulate pressure.

  As described above, the device for applying the braking force to the door body 1 when closing and moving toward the fully closed position is not limited to the cylinder-type braking device 53. For example, the door body 1 and an upper frame member 10, and a rotary damper device having a pinion member attached to the other and meshing with the rack member. The pinion member may be rotated by the closing movement toward the closing position, and a braking force may be generated by a viscous substance or the like filled in the rotary damper device.

  As shown in FIG. 1, a door contact member 57 that is a stop member facing the door body 1 in the opening and closing movement direction of the door body 1 is provided on the upper and lower parts of the frame member 12 on the door bottom side. It is attached with a fastener such as a screw. These door contact members 57 made of an elastic material such as rubber define a substantially backward limit position which is a substantially open movement limit position of the door body 1, and the end of the door body 1 on the door bottom side is the door stop. When abutting against the member 57, the door body 1 reaches a substantially backward limit position, that is, a substantially fully open position.

  In addition, since it is arrange | positioned in the edge part by the side of the entrance / exit 2 in the door pocket 3 as shown in FIG. The finger padding prevention member 60 is attached to reduce the distance between the collar frame member 13 and the door body 1 and prevent a finger or the like from being caught in the gap between the collar frame member 13 and the door body 1. It has been.

  The finger padding prevention member 60 formed of an elastic material such as rubber or soft synthetic resin or a soft material is continuous in the longitudinal direction of the finger padding prevention member 60 which is the vertical direction and is also the longitudinal direction of the frame member 13. It has a split groove (not shown) formed as described above. Among the inner member 23 and the outer member 24 described with reference to FIG. 3 constituting the frame member 13, the outer member 24 is provided with an inner extending portion 24B extending inward in the thickness direction of the door pocket 3, The finger padding preventing member 60 is attached to the frame member 13 by inserting the inner extending portion 24B into the split groove.

  Next, the door body fully open holding device according to an embodiment of the present invention will be described. FIG. 7 is an enlarged view of a side view of the door body full-open holding device 70 according to the present embodiment shown in FIG. 5, and FIG. 8 is a view in the direction of arrow VIII (front view) of FIG. 9 is a sectional view (longitudinal sectional view) taken along line S9-S9 in FIG. 8, FIG. 10 is a sectional view taken along arrow X in FIG. 7 (plan view), and FIG. 11 is a sectional view taken along line S11-S11 in FIG. Horizontal sectional view).

  As shown in FIG. 5, the door body fully opening holding device 70 according to this embodiment is a door frame side frame member facing the door butt side (opening side) end 1 </ b> A of the door body 1 inside the door pocket 3. 12 is arranged. Then, as shown in FIGS. 7 and 8, the door body fully open holding device 70 includes a magnet 71 (for example, a neodymium magnet, a ferrite magnet, etc.) that is a vertically long rectangular plate-like magnet member that is long in the vertical direction. And an attachment member 72 for attaching the magnet 71 to the collar frame member 12.

  The attachment member 72 includes a base 73 attached to the frame member 12, a holding part 74 that holds the magnet 71, both ends of the holding part 74, and both ends of the base 73 (in FIG. 8, the thickness of the door body 1). And the elastic deformation portion 75 that is elastically deformable in the opening / closing movement direction of the door body 1. The holding part 74 has a storage part 74A in which the magnet 71 is stored, and has a hollow shape with open end faces 74B and 74C in the vertical direction. The magnet 71 has an opening end 74B or an opening end 74C of the holding part 74. And is fixed by adhesion or the like inside the storage portion 74A.

  The base portion 73 is made of hard rubber, the holding portion 74 and the elastic deformation portion 75 are made of soft rubber, and the mounting member 72 is an extrusion molding or pultrusion made of hard rubber and soft rubber which are elastic members. It is an integrally molded product by molding.

  Therefore, the elastically deforming portion 75 that is curved inward in the thickness direction of the door body 1 (the left-right direction in FIGS. 10 and 11) moves the door body 1 to open relative to the magnet 71 held by the holding portion 74. When an external force in the direction (downward in FIG. 10) is applied, the door body 1 is further curved (elastically deformed) inward in the thickness direction (left-right direction in FIGS. 10 and 11). The elastic deformation part 75 is elastically deformed, and an elastic force for returning to the original shape is accumulated in the elastic deformation part 75.

  As shown in FIG. 9, the attachment member 72 in a state where the magnet 71 is held by the holding portion 74 has a hollow portion 72 </ b> A and is in a direction orthogonal to or substantially orthogonal to the opening / closing movement direction of the door body 1. Therefore, the attachment member 72 in a state in which the magnet 71 is held by the holding portion 74 is a hollow member.

  As shown in FIGS. 8 and 9, the base 73 of the attachment member 72 is fixed to the frame member 12 by two upper and lower fixing members 76. These fixing members 76 having the same or substantially the same shape and structure as each other are formed by bending a metal plate material, extend in the vertical direction, and are fixed to the flange frame member 12 by a fixing tool 77 such as a screw. A first front portion 76A that is a fixed portion, a horizontal portion 76B that extends in the horizontal direction from the distal end of the first front portion 76A toward the closing side of the door body 1, and a base portion 73 from the distal end of the horizontal portion 76B. And a second front surface portion 76 </ b> C that is a support portion that supports the surface 73 </ b> A on the side facing the holding portion 74 in the base portion 73 of the attachment member 72.

  The second front portion 76C of each fixing member 76 is inserted from both open ends 72B and 72C of the mounting member 72 (in other words, the open ends 72B and 72C), and the first front portion 76A is fixed to a screw or the like. Each second front surface portion 76 </ b> C supports the surface 73 </ b> A on the side facing the holding portion 74 in the base portion 73 of the mounting member 72 by pressing and supporting the frame member 12 with the tool 77. . In this way, as shown in FIG. 9, the mounting member 72 includes two fixed members arranged symmetrically with respect to a horizontal line passing through a middle point or a substantially middle point in the longitudinal direction that is the vertical direction of the mounting member 72. The member 76 is fixed to the collar frame member 12.

  On the other hand, the door body 1 is formed of steel, which is a magnetic member that can be attracted to the magnet 71 disposed on the frame member 12.

  Next, the operation of the door body fully open holding device 70 will be described. FIG. 12 is a diagram illustrating a case where the door bottom end 1A of the door body 1 is in contact with the door contact member 57 and the elastic deformation portion 75 of the mounting member 72 of the door body fully opening holding device 70 is elastically deformed. It is a figure similar to above-mentioned FIG.5 and FIG.6. FIG. 13 is an enlarged cross-sectional view of the door body full-open holding device 70 of FIG. 12, and is the same view as FIG. 3 described above.

  As can be seen from FIG. 5 described above, the thickness dimension (in the width direction of the door body 1) of the mounting member 72 of the door body fully opening holding device 70 before the magnet 1 is attracted to the opening 1 </ b> A of the door body 1. The dimension (L1 in the left-right direction) L1 is larger than the thickness dimension (dimension in the left-right direction) L2 of the two upper and lower door contact members 57. For this reason, when the operator opens and moves the door body 1 while holding the grip portion 52, the end 1A on the door bottom side of the door body 1 first comes into contact with the mounting member of the door body fully opening holding device 70. 72 holding parts 74. At this time, the door body 1 formed of steel that is a magnetic member is in a state of being attracted to the magnet 71 that is a magnet member that is held by the holding portion 74 of the mounting member 72.

  Thereafter, when the operator further opens and moves the door body 1, the thickness dimension of the attachment member 72 gradually decreases because the elastic deformation portion 75 formed of soft rubber is elastically deformed. Then, when the door body 1 is further opened and moved, and the end 1A on the door bottom side of the door body 1 comes into contact with the door stop member 57 as shown in FIG. As shown, the elastic deformation of the elastic deformation portion 75 of the mounting member 72 is maximized, and the thickness dimension of the mounting member 72 is minimized. That is, the opening side end 1 </ b> A of the door body 1 is in contact with the door stop member 57 because the elastic deformation portion 75 of the attachment member 72 is elastically deformed. It is when it becomes the same as the thickness dimension.

  Thereafter, when the operator releases his / her hand from the grip portion 52, the door body 1 is slightly changed by the door body automatic closing device 50 until the elastic deformation portion 75 returns to the original shape (the state before elastic deformation). Close and move. However, when the elastically deforming portion 75 returns to its original shape, the spring force accumulated in the spiral spring of the spiral spring mechanism of the door body automatic closing device 50 (more precisely, the door body) due to the string-like member 51 being drawn out. The spring force for closing and moving the same (hereinafter the same) is smaller than the magnetic force of the magnet 71 of the door body fully open holding device 70 (more precisely, the magnetic force for holding the door body 1 in the fully open state; the same applies hereinafter). ing. For this reason, after the elastic deformation part 75 returns to the original shape, the door body end 1A on the door bottom side of the door body 1 continues to be attracted to the magnet 71 held by the holding part 74 of the mounting member 72, thereby the door body. 1 is prevented from moving and the door 1 is kept fully open.

  As described above, in the present embodiment, the door body 1 is not fully opened when the opening-side end portion 1A of the door body 1 is in contact with the door contact member 57, as shown in FIG. This is when the elastically deforming portion 75 elastically deformed by contact with the opening-side end portion 1A is slightly closed and moved until it returns to its original shape (the state before elastic deformation). In other words, in the present embodiment, the fully open position of the door body 1 is not the position when the opening-side end portion 1A of the door body 1 abuts against the door contact member 57, but a position slightly closed from this position. ing.

  In the present embodiment described above, the door body fully-open holding device 70 for holding the door body 1 in the fully open state is attached to the eaves frame member 12 that is stationary with respect to the door body 1 via the attachment member 72. Thus, the door 71 formed of steel, which is a magnetic member, serves as a magnet 71, which is a magnet member to be attracted.

  That is, in this embodiment, the fully open state of the door body 1 is that the locking member formed by bending the leaf spring is locked to the locked member by the small diameter roller, as in the conventional example described above. The door body 1 is held by being attracted to the magnet 71 instead of being held by.

  For this reason, according to this embodiment, a possibility that the fall of the fully open holding | maintenance performance of the door body 1 by long-term use of the door body fully open holding | maintenance apparatus 70 will become smaller. That is, according to this embodiment, the fully open holding performance of the door body 1 can be further improved.

  Moreover, in this embodiment, the door body full open holding device 70 is comprised with the magnet 71, and it is not necessary to prepare the magnetic member attracted | attached to this magnet 71 separately from the door body 1, and the door body 1 itself is made of steel. Since it suffices to form it, the structure of the door body fully open holding device 70 can be simplified, and as a result, the entire structure of the sliding door device can be simplified.

  In this embodiment, the magnet 71 is attached to the frame member 12 via the attachment member 72, and the attachment member 72 holds the base 73 attached to the frame member 12 and the magnet 71. Part 74, and both ends of this holding part 74 and both ends of base 73 (in FIG. 8, both ends in the left-right direction, which is the thickness direction of door body 1), are included. The elastic deformation portion 75 is configured to be elastically deformable in the opening / closing movement direction of the door body 1.

  For this reason, according to the present embodiment, when the door butt side end 1A of the door body 1 comes into contact with and attracts the magnet 71, the door butt side end 1A of the door body 1 receives from the magnet 71. Is smaller when the elastic deformation portion 75 of the mounting member 72 is elastically deformed.

  In the present embodiment, the holding portion 74 of the attachment member 72 covers the surface of the magnet 71 that faces the door body 1.

  For this reason, according to the present embodiment, when the door butt side end 1A of the door body 1 contacts and attracts the magnet 71, the door butt side end 1A of the door body 1 and the magnet 71 directly contact each other. Therefore, damage to the end 1A and / or the magnet 71 on the door bottom side of the door 1 can be prevented.

  In this embodiment, the door frame member 12 is provided with a door contact member 57 with which the end 1A on the door butt side of the door body 1 abuts when the door body 1 is opened and moved, as shown in FIG. Thus, the thickness dimension L1 which is the dimension of the opening / closing movement direction (left-right direction) of the door body 1 of the attachment member 72 before the door 1 end 1A of the door body 1 is attracted to the magnet 71 is the door contact member. It is larger than the thickness dimension L2 of 57.

  For this reason, according to this embodiment, the impact force received when the opening-side end portion 1A of the door body 1 abuts against the door stop member 57 is such that the mounting member 72 of the door body 1 precedes the door stop member 57. The contact is made with the end 1A on the opening side, and the elastic deformation portion 75 of the mounting member 72 is elastically deformed, which is further reduced.

  In the present embodiment, as described above, when the door body 1 has reached the fully open position, the door body automatic closing device 50 applies the moving force to the closing side applied to the door body 1, that is, the door body automatic closing. The spring force accumulated in the spiral spring of the spiral spring mechanism when the string-like member 51 is drawn out from the device 50 is smaller than the magnetic force of the magnet 71 of the door body fully-open holding device 70 (force that attracts the door body 1). (The same applies to a door fully open holding device according to another embodiment described later). In other words, when the door body 1 reaches the fully open position, the magnetic force for holding the door body 1 in the fully open state is larger than the force for closing the door body 1 by the door body automatic closing device 50. ing. For this reason, the fully open state of the door body 1 is held by the magnetic force of the magnet 71 of the door body fully open holding device 70.

  Further, in the present embodiment, when the opening-side end portion 1A of the door body 1 that has been opened and moved approaches the magnet 71 of the door body fully open holding device 70 to a certain distance, the magnet 71 of the door body fully open holding device 70. Is larger than the spring force of the spiral spring of the door body automatic closing device 50, and thereafter the door body 1 is opened and moved by the magnetic force of the magnet 71 of the door body fully opening holding device 70 ( The same applies to a door body fully open holding device according to another embodiment to be described later). Here, the “certain distance” can be arbitrarily set by changing the magnetic force of the magnet 71 of the door body fully-open holding device 70. For example, the opening-side end portion 1A of the door body 1 that is opening and moving is used. When the distance (interval) with the magnet 71 of the door body fully opening holding device 70 is about 2 to 3 cm, the magnetic force of the magnet 71 of the door body fully opening holding device 70 is the spring force of the spiral spring of the door body automatic closing device 50. You may set so that it may become larger.

  On the other hand, when the end 1A on the opening side of the door body 1 being closed and moved away from the magnet 71 of the door body fully open holding device 70 to a certain distance, the spring force of the spiral spring of the door body automatic closing device 50 is Since the magnetic force of the magnet 71 of the door body fully opening holding device 70 is greater, the door body 1 is closed and moved by the spring force of the spiral spring of the door body automatic closing device 50 thereafter (separate implementation described later). The same applies to the door body fully open holding device according to the embodiment). Here, “a certain distance” can be arbitrarily set by changing the magnetic force of the magnet 71 of the door body fully open holding device 70 as described above. When the distance (interval) between the opening-side end portion 1A and the magnet 71 of the door body fully opening holding device 70 is about 4 to 5 cm, the spring force of the spiral spring of the door body automatic closing device 50 is changed to the door body fully opening holding device. You may set so that it may become larger than the magnetic force of 70 magnets 71. FIG.
