Description

  The present invention relates to a sliding door structure including a sliding door that moves along a rail.

  In this type of conventional sliding door, when the sliding door is moved and brought into contact with the door frame (side door) or the side edge of another sliding door and stopped, when the sliding door comes close to the door frame, etc. Various proposals have been made to decelerate (see Patent Document 1).

  The thing of patent document 1 uses the damper in order to relieve a collision sound, and a moving speed is weakened at the moment when the rod of a damper collides with a door frame. Further, this is configured such that when the sliding door is moved away from the door frame, only the sliding door moves while the rod is attracted to the permanent magnet by providing a permanent magnet in the door frame. In other words, the rod is pulled out by the separation operation of the sliding door from the door frame, and the damper is restored.

  Hereinafter, an embodiment of a sliding door structure according to the present invention will be described with reference to the accompanying drawings.

  In this embodiment, the sliding door structure of the storage shelf 3 provided on the living side of the face-to-face kitchen counter 1 is illustrated as the sliding door structure.

  As shown in FIGS. 1 and 4A, the kitchen counter 1 has a cooking unit 2 having a sink 2a and a heating cooker 2b on the kitchen side, and is integrated with the cooking unit 2 on the living side. The structure further includes a storage shelf 3 (storage unit 10).

  As shown in FIGS. 1 and 4 (b), the storage portion 10 is formed with a storage space surrounded by a back plate 10b, side plates 10a and 10a, a bottom portion 10c, and a top plate 10f. . The storage space is partitioned by the partition plates 10d and 10d to form three small storage portions 12, 12, and 12 arranged side by side. A plurality of storage shelves partitioned by a plurality of shelf boards 10e are formed in the spaces of the respective small storage portions 12, 12, and 12.

  The three small storage parts 12, 12, and 12 are substantially the same size in front view. The storage unit 10 includes two sliding doors 20 and 20 that substantially match the size of the small storage unit 12 in a front view so as to be movable along the rail. That is, in a state where the two sliding doors 20 and 20 are moved to both ends of the opening 11, for example (in FIG. 4B, both sliding doors 20 and 20 are indicated by a two-dot chain line), the opening 11 of the storage unit 10 is approximately 2/3 is blocked and a partial opening is formed between the sliding doors 20 and 20.

  In the sliding door structure of the present embodiment, the two sliding doors 20 and 20 are not different from each other (the sliding doors 10 and 10 do not overlap each other), and are mutually along the same rail (the upper rail 14 and the lower rail 15). It is possible to move in the lateral direction so as to be close to and away from. Accordingly, when the adjacent side end portions 21, 21 of the two sliding doors 20, 20 are brought close to each other, they are close to each other at any position within the partial opening located on the front surface of the small storage portion 12 at the center. It will come into contact. In FIG. 4B, the upper and lower rails 14 and 15 are schematically shown. As for the lower rail 15, an enlarged partial longitudinal sectional view is shown in FIG. 5B.

  The upper rail 14 has a roller (not shown) that suspends and supports the sliding door 20 attached to the front portion of the top plate 10f of the storage unit 10, and the roller is integrated with a damper (not shown) to form a soft closer mechanism. Is configured. Thus, when the sliding door 20 is moved to the side plate 10a side, the sliding door 20 is decelerated in the vicinity of the side plate 10a, and the sliding door 20 is prevented from colliding with the door frame with a strong momentum or repelling. Note that a sliding door structure shown in FIG. 8 described later may be applied to this soft closer mechanism.

  On the other hand, as shown in FIGS. 5A and 5B, the lower rail 15 is disposed in the kicking space 13 below the bottom 10 c of the storage unit 10. Specifically, the lower rail 15 includes a fixing portion 16 having a substantially L-shaped cross section and a rail portion 17. As shown in FIG. 5B, the fixing portion 16 is fixed so as to straddle the back surface of the bottom portion 10c of the storage portion 10 and the wall surface of the kick wall 13a. A rail portion 17 composed of two plate pieces 17a and 17a projecting downward is formed at the tip of the fixed piece 16a fixed to the bottom 10c of the storage portion 10 in the fixed portion 16.

  On the other hand, a sliding member 22 guided along the rail portion 17 is fixed to the sliding door 20 on the back side of the lower end thereof. The sliding portion 24a of the sliding member 22 slides between the two plate pieces 17a, 17a of the lower rail 17, so that the sliding door 20 can move laterally without rattling at the lower end. ing. With the upper rail 14 and the lower rail 15, the sliding doors 20 and 20 can move smoothly.

  As shown in FIG. 1B, the sliding door 20 has a side end 21 of the sliding door 20 along the moving direction of the sliding door 20 on one of the adjacent side ends 21, 21 of the sliding door 20, 20. A projecting body 31 that can be moved forward and backward is provided. The projecting body 31 is provided so that the projecting body 31 can advance and retract in a piston motion with respect to the cylindrical body 32 fixed to the sliding door 20. The abutting body 30 includes the protruding body 31, the cylindrical body 32, a damper 34 and a compression coil spring 33 described below. In FIG. 1C, the schematic structure of the speed reduction mechanism G is shown in a longitudinal sectional view.

  Further, a contacted portion 41 with which the distal end portion 30a of the contact body 30 (projecting body 31) contacts is provided at the side end portion 21 of the other sliding door 20. As an example, a contact body 30 is provided on the right sliding door 20 and a contacted portion 41 is provided on the left sliding door 20.

  The protrusion 31 is connected and fixed to a main body 34 a of a damper 34 (oil damper), and the tip of a rod 34 b of the damper 34 is fixed to the bottom of the cylindrical body 32. A compression coil spring 33 is attached to the rod 34 b, and one end of the compression coil spring 33 is fixed to the main body 34 a of the damper 34 and the other end is fixed to the bottom of the cylinder body 32.

  When the rod 34b extends and the damper 34 is in the return state, the compression coil spring 33 is also in the elastic return state at the same time. Further, when the protruding body 31 is retracted into the cylindrical body 32, the rod 34b compresses the oil inside the main body 34a, and the rod 34b coming out of the main body 34a becomes shorter, and at the same time, the compression coil spring. 33 is also pressed by the main body 34a and contracts.

The return of the damper 34 from the compressed state is made by the elastic return force of the compression coil spring 33. That is, there is little or no restoring force of the damper 34 (the rod 34b) due to the oil in the main body 34a, and even if there is, the restoring force is an elastic restoring force of the compression coil spring 33. Small enough than.

  Further, a permanent magnet 35 for adsorbing a contacted portion 41 to be described below is housed in the distal end portion 30a of the protruding body 31. The permanent magnet 35 may be provided on the outer surface of the protruding body 31.

  The adsorbing force of the permanent magnet 35 against the contacted portion 41 is less than the minimum force required to move the cylindrical body 32 and the protruding body 31 of the contact body 30 from the contracted state to the most extended state. Is sufficiently large. However, when the two sliding doors are in a stopped state due to the magnetic attachment between the permanent magnet 35 and the iron part, when a force is applied to separate one sliding door from the other sliding door, the magnetic attachment is not released. There is not enough adsorption power to move with a sliding door.

  Further, the abutted portion 41 is composed of an upright plate piece made of an iron plate having a surface with which the tip portion 30a of the projecting body 31 abuts. In the present embodiment, the L-shaped body 40 including the upright plate piece (contacted portion 41) is formed by bending an iron plate. That is, the upright plate piece constituting the contacted portion 41 and the mounting plate piece 42 fixed to the sliding door 20 are integrally formed. By attaching the attachment plate piece 42 to the back side of the sliding door 20, the contacted portion 41 is fixed to the sliding door 20.

  The contacted portion 41 may be formed of a material other than the iron plate as long as it is a material such as a ferromagnetic material to which the permanent magnet 35 is attracted. Further, the abutting portion 41 may be configured by embedding an iron portion in a part of the standing plate piece, or the abutting portion 41 may be formed by attaching an iron plate to a surface of the standing plate piece facing the abutting body 30. May be configured.

  A reduction mechanism that decelerates sliding movement of the sliding door in the stopping operation of the side end 21 of the sliding door 20 with respect to the side end 21 of the mating sliding door 20 by the contact body 30 and the contacted portion 41 configured as described above. G is configured.

  The contact body 30 and the contacted portion 41 are fixed to the sliding members 22 and 22 attached to the sliding doors 20 and 20 so as to face each other at the lower end side portions 21 and 21 of the sliding doors 20 and 20. .

  Next, an installation structure of the abutting body 30 including the projecting body 31 and constituting the advance / retreat mechanism and the L-shaped body 40 including the contacted portion 41 will be described together with the shape and structure of the sliding member 22.

  As shown in FIGS. 5A and 5B, the sliding member 22 is formed between a fixed portion 23 having a substantially L-shaped cross section and two plate pieces 17a and 17a constituting the rail portion 17 of the lower rail 15. And a moving part 24 that stands up to be inserted and has a sliding part 24a at the tip. An extension piece 25 having a substantially L-shaped cross section extending in the direction toward the kick wall 13a is further formed at the rear end portion of the fixed portion 23 of the sliding member 22 (base portion of the moving portion 24). The extending piece 25 has a horizontal piece 25a extending toward the kick wall 13a.

  As shown in FIG. 1 (b), each of the contact body 30 and the L-shaped body 40 is a horizontal piece of extended pieces 25, 25 of sliding members 22, 22 connected to the corresponding sliding doors 20, 20. It is being fixed on 25a, 25a. Specifically, the abutting body 30 is fixed by horizontally fixing the cylindrical body 32 to the horizontal piece 25a, and the L-shaped body 40 is fixed by bonding the mounting plate piece 42 to the horizontal piece 25a.

  Next, the operation of the speed reduction mechanism G will be described with reference to FIGS. The operations shown in these drawings are the same for the deceleration operation, but the operations when the sliding doors 20 and 20 are separated are different from each other.

  As shown in FIGS. 2A to 2F, the upright plate piece (contacted portion 41) constituting the contacted portion 41 has a plate surface that is in front of the side end surface of the sliding door 20. Almost the same position. In the state where the speed reduction mechanism G does not operate, the protruding body 31 is in a state in which a predetermined length protrudes toward the sliding door 20 opposite to the side end face of the sliding door 20 as shown in FIG.

  Next, the operation when the sliding doors 20 and 20 are run on the rails at a predetermined speed so as to be close to each other will be described with reference to FIGS. In addition, although the example which moves the sliding door 20 which has the contact body 30 was shown in FIG. 2, when moving the sliding door 20 which has the L-shaped body 40 (contacted part 41), or both sliding doors 20 and 20 Even when they are moved together, the advancing / retreating mechanism operates in the same manner as described below, and therefore the illustration of these operations is omitted. Further, as shown in FIG. 1A, the sliding door 20 having the L-shaped body 40 is brought to the left side plate 10a side and cannot move further to the left.

  First, the sliding door 20 provided with the contact body 30 is moved to the left side in the drawing at a predetermined speed (the size of the white arrow in FIG. 2 and FIG. 3 represents the speed). At this time, the compression coil spring 33 and the damper 34 housed in the cylindrical body 32 are in a return state, and the compression coil spring 33 hardly fluctuates even during movement at a constant speed, and the damper 34 does not operate. The sliding door 20 moves toward the mating sliding door 20 while the projecting dimension from the cylindrical body 32 remains unchanged.

  Then, the sliding door 20 comes close to the mating sliding door 20, the tip 30a of the projecting body 31 abuts against the abutted portion 41 of the mating sliding door 20, and at the same time, the permanent magnet 35 of the abutting body 30 contacts the abutting portion. 41 is adsorbed. At the same time, the projecting body 31 presses the contacted portion 41, but the sliding door 20 on the other side cannot move, so that the damper 34 and the compression coil spring 33 are pressed by the reaction and start to contract.

  Thus, the damper 34 and the compression coil spring 33 act as a buffer body, and the side end 21 of the sliding door 20 having the contact body 30 is replaced with the side end 21 of the sliding door 20 having the contacted portion 41. The speed of approaching is small. When the projecting body 31 is gradually submerged in the cylindrical body 32, the side end portions 21 and 21 of the sliding doors 20 and 20 are closest (contacted) to each other, and the sliding door 20 having the contact body 30 is stopped. Moreover, the protrusion degree from the side edge part 21 of the sliding door 20 of the protrusion 31 becomes the minimum.

  In a state where the sliding doors 20 and 20 are closest and stopped (see FIG. 2D), naturally, the elastic return force of the compression coil spring 33 is generated. However, the sliding doors 20 and 20 are not separated by using the compression coil spring 33 having an elastic coefficient that does not separate the sliding doors 20 and 20. Therefore, both the damper 34 and the compression coil spring 33 are maintained in a contracted state, and the state in which the sliding doors 20 and 20 are in closest contact is maintained unless an external force is applied.

  Moreover, since the contact body 30 and the contacted portion 41 are in a fixed relationship by the attractive force of the permanent magnet 35, the contraction state of the damper 34 and the compression coil spring 33 and the attractive force of the permanent magnet 35 are mixed. Thus, there is almost no possibility that the side end portions 21 and 21 of the sliding doors 20 and 20 are separated from each other.

  As described above, the projecting body 31 (abutment body 30) that can be moved forward and backward is provided on one of the sliding doors 20 and 20 of the storage unit 10 and the abutted part 41 is provided on the other side. When the sliding doors 20, 20 come close to each other and the tip 30 a of the projecting body 31 comes into contact with the contacted portion 41, the proximity speed of the sliding door 20 to the other sliding door 20 decreases. Therefore, even when a finger is attached to the side end portion 21 of the sliding door 20 having the abutted portion 41, there is no possibility that finger filling will occur. Even if you put your finger between the sliding doors 20, 20, the proximity speed has dropped sufficiently so that you will not be injured.

  Moreover, since such a deceleration mechanism G is attached to the kicking space 13 on the back surface side of the lower end of the sliding doors 20 and 20, they are not visible from the outside, and there is almost no risk of impairing the aesthetic appearance.

  Next, in the stop state of FIG. 2D, an operation of pulling the sliding door 20 provided with the contact body 30 away from the counterpart sliding door 20 is performed. Then, since the attractive force of the permanent magnet 35 is sufficiently large, as shown in FIG. 2 (e), the tip 30 a of the projecting body 31 is attracted and fixed to the contacted part 41, and the contact body 30 Only the cylinder 32 moves with the sliding door 20. When the contact body 30 is in the most extended state, that is, when the damper 34 and the compression coil spring are in the return state, the distal end portion 30a of the contact body 30 is separated from the contacted portion 41 ( (Refer FIG.2 (e) (f)).

  As described above, the contact body 30 and the contacted portion 41 are configured so as not to be separated by the attractive force of the permanent magnet 35, so that the damper 34 can be returned to the return state by the separation operation of the sliding door 20. it can. Of course, the maintenance of the stop state by the contact between the sliding doors 20 and 20 can also be achieved by the attractive force of the permanent magnet 35.

  Next, the case of FIG. 3 will be described. 3 (a) to 3 (d) are explanatory diagrams of the deceleration operation, but since they operate in the same manner as FIGS. 2 (a) to 2 (d), description thereof is omitted.

  When the sliding door 20 on the right side in the drawing is moved to the right side in order to separate the sliding doors 20 and 20 in the stopped state of FIG. 3D, as shown in FIG. 3E due to various conditions such as shaking of the sliding door 20. In addition, the permanent magnet 35 and the contacted portion 41 may be separated before the contact body 30 returns to the most extended state.

  In such a case, at the moment when the sliding doors 20 and 20 are separated from each other, the protruding body 31 of the contact body 30 is in a state of being immersed in the cylindrical body 32 as shown in FIG. However, immediately after that, the elastic return force of the compression coil spring 33 acts to return the damper 34 to the return state. Then, as shown in FIG. 3F, the compression coil spring 33 is elastically restored, and at the same time, the damper 34 is returned to the restored state.

As described above, when the sliding door 20 is separated from the other sliding door 20, the damper 34 is relatively early after the separation operation is started by the action of the attractive force of the permanent magnet 35 or the elastic return force of the compression coil spring 33. Can be returned to the return state.

  In the above embodiment, the example in which the sliding door 20 provided with the contact body 30 is moved is shown. However, even when the sliding door 20 provided with the contacted portion 41 is moved, the permanent magnet 35, It goes without saying that the damper 34 is restored by any action of the compression coil spring 33.

  In the embodiment described above, the sliding door structure in which the two sliding doors 20 and 20 are moved on the same rail in the storage shelf 3 has been described. However, the speed reduction mechanism G described above is an individual sliding door on each of the two rails. The present invention can also be applied to a storage shelf having a sliding sliding door structure in which 20 and 20 move.

  FIGS. 6 and 7 both show examples in which the speed reducing mechanism G acts to come close to each other while decelerating when the sliding door 20 comes into contact (collision) with the counterpart sliding door 20. These drawings schematically show the sliding door structure in a plan view. In the figure, 10a is a side plate of the storage shelf, and 15 is a lower rail.

  In the example of FIG. 6, as in the embodiment of FIG. 1, the contact body 30 is provided on the back surface side of the side end portion 21 of one sliding door 20, and the protrusion 31 of the contact body 30 is formed on the back surface of the other sliding door 20. The abutted portion 41 is provided so that the distal end portion 30a can abut.

  The contact body 30 and the contacted portion 41 are configured such that when the sliding door 20 on the back side (left side in the figure) is opened, the contact body 30 attached to the sliding door 20 is attached to the other sliding door 20. The back sliding door 20 stops in a state where the permanent magnet 35 attracts the contacted portion 41 (see FIGS. 6A and 6B).

  In this way, in the example of FIG. 6, the speed reduction mechanism G operates when the rear sliding door 20 is opened, so the handle 22 provided on the front surface of the rear sliding door 20 is the front sliding door 20 (right side in the figure). It is possible to prevent the fingers from coming into contact with the side end portion 21 or pinching fingers between the side end portion 21.

  Further, when closing the sliding door 20 on the back side, the damper 34 and the compression coil spring 33 (see FIG. 2, etc.) are operated by the operation of either FIG. 2 (e) (f) or FIG. 3 (e) (f). Returns to the return state.

  The example of FIG. 7 is the same as the example of FIG. 6 in terms of purpose, but the part provided with the contacted portion 41 is different from the example of FIG. That is, in the example of FIG. 7, the contacted portion 41 is provided at the back of the door frame (door contact) of the right side plate 10 a of the sliding door 20 on the near side. In addition, the contact body 30 is provided in the position along the rail to which the back sliding door 20 moves in planar view.

  As in the example of FIG. 7, the contact between the handle 22 and the sliding door 20 and the finger padding can be prevented by providing the contact body 30 and the contacted portion 41 in the illustrated portion.

  As described above, the example of FIG. 6 and the example of FIG. 7 have the same effect, but either one may be selected as appropriate depending on the installation situation, the shape and size of the member, and the like.

  6 and 7 do not clearly show the exact attachment position (particularly the height position) of the contact body 30 and the contacted portion 41, but attach it at a position where the external appearance is not exposed as in the example of FIG. It is desirable aesthetically.

  Moreover, as shown in FIG. 8, said sliding door structure can be utilized also as a sliding door collision prevention structure with respect to the door frame (door stop) of the side plate 10a. Thereby, the finger padding between the sliding door 20 and the door frame can be prevented.

  The various embodiments described above relate to the sliding door structure in the storage shelf, but can also be applied to a sliding door structure other than the storage shelf. For example, the present invention can be applied to a sliding door structure in a door device having a door frame and two sliding doors, a partition door device in which a plurality of sliding doors are movable, or the like.

  In the various embodiments described above, an example in which the compression coil spring 33 is continuously connected to the damper 34 so as to enclose the rod 34b of the damper 34 has been shown, but other elastic bodies such as rubber and sponge are used in the cylindrical body 32. It is good also as a structure provided in the peripheral part of the rod 34b.

  In the various embodiments described above, the configuration in which the permanent magnet 35 is provided at the tip 30a of the contact body 30 and the material that can be attracted to the permanent magnet 35 is provided in the contacted portion 41 is shown. 41 may be provided with a permanent magnet 35, and the tip 30 a of the contact body 30 may be provided with a material that can be attracted to the permanent magnet 35.
