Description

  The present invention relates to a support structure for a rotating body that can be easily mounted and appropriately supported, and a drawer device and furniture to which the supporting structure is applied.

  Various types of structures that support a rotating body have been conventionally known. Examples of structures that simply support a rotating body in the furniture field include the structure shown in Patent Document 1.

  In this device, a lock lever, which is a rotating body, is rotatably accommodated on the side wall of the housing so as to form a drawer lock mechanism between the drawer and the drawer device. A plate-like locking lever having a shaft portion at the center of the upper and lower ends is provided in the storage space between the outer plate and the inner plate, at least the front edge of the side wall of the outer plate and the inner plate. It is accommodated so that it can rotate in the thickness direction around the shaft. A lock claw having a number corresponding to the number of steps of the drawer is provided on one rotating edge of the lock lever, and a claw projection opening through which the lock claw can pass is provided on the inner surface of the side wall. The locking claw is urged by an elastic urging mechanism in a direction in which each lock claw is inserted into the side wall, and when the other rotation edge of the locking lever is pressed by a lock operating rod, the lock claw is clawed. It is configured to project from the projecting opening all at once, and each drawer can be locked by the projecting lock claw.

  However, with such a structure, the bearing portion requires fitting accuracy, so that there is a problem that work efficiency when assembling the shaft portion to be supported by the bearing provided in the storage space is poor. Further, in order to maintain the strength of the shaft portion, it is necessary to use a sheet metal or the like for the locking lever, which increases the weight, makes the assembly operation not easy, and makes the operation of the locking lever relatively heavy. Furthermore, since the locking lever must be lifted and inserted into the storage space from the longitudinal direction, the work is complicated and there are problems such as many restrictions on the work space.

  The present invention provides a support structure for a rotating body that is useful for easily and appropriately supporting various rotating bodies in the field of furniture, including such a locking lever, together with a drawer device and other furniture to which the rotating body is applied. It is intended to provide.

  In order to achieve this object, the present invention takes the following measures.

  That is, when the rotating body is accommodated in the storage space having one or two or more flat portions, the rotating body support structure according to the present invention has an outer peripheral surface and the rotation body is accommodated in the storage space. The body is configured to be guided in the rotational direction by bringing the outer peripheral surface into contact with the flat surface portion, and at least one end surface in the longitudinal direction of the rotating body is formed into a planar shape or a curved surface, and the one end surface is configured as the storage space. The rotating body is rotatably supported in contact with the corresponding inner surface. At least one end surface in the longitudinal direction refers to an end surface located at an end in the vertical direction when the rotating body is arranged vertically. In the case where a rib or the like is provided on the end surface, a mode of contacting only by a portion such as the rib is also included, and it is not always necessary that the entire one end surface is in contact.

  If comprised in this way, since a bearing structure with high fitting precision is not required, it can be assembled easily and operated effectively. Further, since it is not necessary to provide a fragile shaft at the end of the rotating body, the strength can be effectively increased even if the rotating body is made of resin or the like.

  When the storage space is surrounded by at least the inner plate and the outer plate, in order to improve workability when storing the rotating body, the rotating body can be inserted into and removed from the inner plate in a direction perpendicular to the longitudinal direction. It is desirable to provide an opening.

  In the case where the opening is shorter than the longitudinal dimension of the rotating body, it is conceivable that the opening is inserted in a so-called steadily manner. When it is formed in a state that is substantially the same as or longer than the dimension, the removal restriction that restricts the removal of the rotating body by displacing the rotating body in the longitudinal direction after insertion in a part of the rotating body It is desirable to configure the part.

  In order to more easily and appropriately support the rotation of the rotating body, the rotating body includes a reference line portion that engages with one side edge of the opening, an inner surface of the outer plate that is a flat surface, and the other side of the opening. It is desirable to have an outer peripheral surface that moves while maintaining contact with or close to the edge.

  In particular, since the support structure of the present invention does not require a bearing portion, as a particularly suitable rotating body, a lock mechanism is formed between the operating body and the locking structure is locked outward from the rotating body. The claw is protruded, and the lock claw is protruded and retracted from the opening provided in the inner plate as the rotating body rotates in the forward / reverse direction at the retracted position, and engages with the operating body when protruding to lock its operation. What is constructed is useful.

  In order to effectively define the operating range of the rotating body with a simple structure, a restricting portion is provided toward the outside of the rotating body, and the restricting portion is abutted against the inner plate so that at least one of the rotating bodies is provided. It is preferable that the rotation is restricted.

  As described above, the strength, durability, and the like can be improved even if the rotating body is integrally molded with resin, and various merits of using the resin can be pursued.

  As a preferred application example of the present invention, it is effective to configure the drawer device by applying the above support structure, and a locking lever that constitutes a lock mechanism between the rotating body and the drawer that is the operating body. Yes, the locking lever is accommodated in the storage space provided on the side wall of the housing for storing the drawer, and the locking claw protrudes outward from one end of the locking lever, and in addition to the locking lever from the locking portion at the storage position. When the end is pressed, the locking claw provided at one end of the locking lever protrudes and retracts from the opening provided in the side wall of the housing as the locking lever rotates in the forward and reverse direction, and is provided in the drawer. It is effective to selectively engage with the engaged portion to lock the drawing operation.

  Of course, if the above support structure is applied, it is possible to easily and properly support various furniture rotating bodies.

  Since the present invention has the configuration described above, it is not necessary to provide a highly accurate bearing structure or a fragile shaft at the end of the rotating body, and the rotating body can be simply made without losing its strength and easily incorporated. Thus, it is possible to provide a new and useful rotating body support structure that can be appropriately operated.

  In such a configuration, the present embodiment applies the present invention to the locking lever 61 that is a rotating body to realize a simple assembly to the side plate 11 of the housing 1 and the drawer 2 that is a moving body. The locking and unlocking operations for 3 and 4 are appropriately performed.

  More specifically, in the present embodiment, the flat space of the front reinforcing portion 11x is used as the storage space S, and the inner plate 11c is continuous in the vertical direction through which the locking lever 61 passes as shown in FIG. The opening 10 is provided, and the locking lever 61 is moved in a direction perpendicular to the longitudinal direction to be inserted into the opening 10.

  The locking lever 61 is made by resin integral molding, and is mainly composed of a lever main body 61x in which a large number of ribs are combined, and the lock claws 61a described above are respectively provided at the upper end portion, the intermediate portion and the lower end portion of the lever main body 61x. 61b, 61c are projected in the horizontal direction, and a restricting portion 61d having a locking surface 61dx on the side facing the inner plate 11c is projected at an appropriate position in the longitudinal direction avoiding the lock claws 61a, 61b, 61c. ing. As shown in FIGS. 6 and 9, etc., the top 61e (FIG. 6: A section) located at the upper end in the longitudinal direction forms a semicircular plate-like portion around the reference line portion z, and the restricting portion 61d. (FIG. 6: B section) is also a semicircular plate-like portion around the reference line portion z, and the bottom 61f (FIG. 6: C section) located at the lower end in the longitudinal direction is also the reference line. A semicircular plate-shaped portion around the portion z is formed, and other appropriate portions in the longitudinal direction (FIG. 6: D section) form a fan-shaped portion 61g around the reference line portion z. The reference line portion z is continuous in the longitudinal direction, and a complementary angle portion 61z having an opening angle smaller than 180 degrees is formed inside the reference line portion z by a stepped portion. A projection 61h as shown in FIGS. 7 and 9 is provided on the top portion 61e, and a torsion coil spring 61j is mounted. One end 61j1 of the top 61e is engaged with a locking piece 61k provided on one end side of the locking lever 61. In addition, the other end 61j2 protrudes laterally beyond a locking piece 61k ′ provided on the other end side of the locking lever 61.

  On the other hand, the opening 10 shown in FIG. 6 and the like is a notch through which the lock claws 61a, 61b, 61c and the other end 61j2 of the torsion coil spring 61j pass through a part of the rectangular main opening 10x corresponding to the lever body 61x. 10a, 10b, 10c, and 10j are provided, and the opening edge on the lower end side is bent toward the storage space S to form a support plate 10f.

  Then, as shown by the imaginary line in FIG. 7, the locking lever 61 is moved in the direction perpendicular to the longitudinal direction so that the other end portion enters first, and the lever body 61x, the lock claws 61a, 61b, 61c, and the torsion coil The spring 61j is inserted into the main opening 10x and the notches 10a, 10b, 10c, and 10j, respectively, rotated at that position, and dropped in the axial direction, so that the bottom 61f is placed on the support plate 10f as shown in FIG. At that position, the lock claws 61a, 61b, 61c are still located in the notches 10a, 10b, 10c, and the other end 61j2 of the torsion coil spring 61j is in a direction to narrow the opening below the notch 10j as shown in FIG. It is configured to be locked to the inner surface of the locking surface 10j2 provided to protrude. The locking lever 61 is formed with a pull-out restricting portion 61m directly below the upper lock claw 61a, and a restricting piece 10m projects below the notch 10a of the opening 10 in the direction of narrowing the opening. The removal restriction part 61m is superposed on the inner surface of the restriction piece 10m in the front-rear direction at the dropped position. Also, a part of the locking lever 61 is provided with a deformable portion 61p (FIG. 7: G section) shown in FIG. 12 that is cantilevered and elastically deformed, and a protrusion 61p ′ is formed on the outer periphery thereof. Has been. The deforming portion 61p is elastically deformed by interfering with the other opening edge 10t when the locking lever 61 is moved in the direction perpendicular to the longitudinal direction and inserted into the opening 10, and the locking lever 61 is dropped from the position. At this time, the protrusion 61p ′ enters the notch 10p provided in the opening edge 10t, and the deformed portion 61 is elastically restored. The protrusion 61p ′ serves as an upward movement restricting portion that restricts the lifting of the locking lever 61.

  When the locking lever 61 is stored, the rails 1a, 1b, and 1c are attached at predetermined positions so as to partially close the opening 10 as shown in FIG. The lock claws 61b and 61c are in a position where they do not interfere with the middle rail 1b and the lower rail 1c, and the lock claws 61b and 61c can be projected and subtracted freely from the notches 10b and 10c, but the lock claws 61a overlap with the upper rail 1a. Therefore, the upper rail 1a is provided with a notch 1ax that protrudes and retracts the lock claw 61a at a position corresponding to the opening of the notch 10a. By attaching the rails 1a, 1b, and 1c, the locking lever 61 is held so as not to fall into the storage space S completely.

  In such a storage position, as shown in FIG. 9, the locking lever 61 and the opening 10 are configured such that the complementary angle portion 61z is engaged with the one side edge 10s of the opening 10 and the reference line portion z is the one side edge 10s. And the outer peripheral surface 61y of each of the top portion 61e, the restriction portion 61d, the bottom portion 61f, and the fan-shaped portion 61g, which are plate-like portions, is in contact with or close to the inner surface of the outer plate 11a. The outer peripheral surface 61y of the plate-like portion provided with the restricting portion 61d is engaged with the other side edge 10t of the opening 10, and the locking lever 61 is guided in the rotational direction as shown in FIGS. You can move while being.

  The locking lever 61 is normally pressed counterclockwise by the torsion coil spring 61j in the plan view, and the restricting portion 61d is in a position engaged with the other side edge 10t of the opening 10 as shown in FIG. The lock claws 61a, 61b, 61c are immersed in the positions indicated by the imaginary lines in FIG. 13 (FIG. 7: E section) and FIG. 14 (FIG. 7: F section), and the second provided on the drawers 1a, 1b, 1c. It exists in the position which does not prevent the movement of the to-be-engaged part 62a, 62b, 62c.

  In this state, when the lock lever 63a is protruded by an operation on the lock portion 63 of the drawer lock mechanism 6 shown in FIG. 5, and the other end portion of the lock lever 61 is pressed by this, the lock lever 61 is shown in FIG. Thus, the bottom 61f is in contact (surface contact) with the support plate 10f, and as shown in FIG. 9, the outer peripheral surface 61y is also a flat surface, the inner surface of the outer plate 11a, and the other side edge 10t of the opening 10. 9 and FIG. 10, the locking lever 61 rotates clockwise as seen in plan view, and the lock claws 61a, 61b, 61c project toward the positions indicated by the solid lines in FIGS. This engages with the second engaged portions 62a, 62b, and 62c of the drawers 1a, 1b, and 1c, and locks the drawing operation.

  As described above, the second engaged portion 62a of FIG. 13A set in the upper drawer 2 is a recess provided in the upper rail 1a, but the middle drawer 3 is pushed in. The situation in which the upper drawer 2 is in the state of being pulled out after locking the locking portion 63 is assumed due to the twisting of the locking lever 61 made of resin. In such a case, if the upper drawer 2 is pushed in with the lock (key) stored, it becomes difficult to remove the lock. Therefore, in this embodiment, a third engaged portion 162a shown in FIG. 5B is recessed further behind the engaged portion 62a of the drawer 2. The engaged portion 162a has a forward-facing slope on the back side of the concave portion, and urges the user to feel that the lock claw 61a gradually falls when the drawer 2 is pushed. With respect to the engaged portion 162a, the lock claw 61a can be detached along the inclined surface and the drawer 2 can be pulled out again, which can be an effective means for preventing lock lockup.

  When the housing 1 shown in FIGS. 1 and 2 is assembled in this way, the top plate D1 is placed on the upper horizontal member 13 and fastened together. In the present embodiment, as shown in FIG. 15, a resin holder 92 is elastically attached in advance to a mounting portion 91 provided on the upper horizontal member 13 to hold the bolt 93, and the bolt 93 is previously attached to the ceiling. The top plate D1 can be easily attached to the housing 1 by being screwed into the insert nut 94 provided on the lower surface of the plate D1.

  As described above, the support structure of the rotating body according to the present embodiment is such that when the locking lever 61 that is the rotating body is stored in the storage space S including the outer plate 11a that is a flat surface, the locking lever 61 is the outer peripheral surface 61y. And the locking lever 61 accommodated in the storage space S is guided in the rotational direction by bringing the outer peripheral surface 61y into contact with the outer plate 11a or the like which is a flat portion, so that the storage space S and the locking lever 61y As a result, there is no need for a bearing structure with high fitting accuracy, and assembly can be performed easily.

  In particular, the bottom 61g, which is one end face in the longitudinal direction of the locking lever 61, has a flat shape, and the bottom 61g is brought into contact with the support plate 10f which is the inner surface provided at a corresponding position in the storage space S. Since the lever 61 is rotatably supported, there is no need to provide a fragile shaft at the end of the locking lever 61. For this reason, even if the locking lever 61 is made of resin or the like, the strength can be effectively increased.

  The storage space S is surrounded by at least the inner plate 11c and the outer plate 11a. The inner plate 11c is provided with an opening 10 that allows the locking lever 61 to be inserted and removed in a direction perpendicular to the longitudinal direction. Therefore, the locking lever 61 can be easily inserted into the storage space S without the complexity of work and the restriction of the work space as in the case of inserting from the longitudinal direction.

  In addition to this, since a part of the locking lever 61 is provided with an extraction restriction part 61m that is displaced in the longitudinal direction after insertion and engages with the inner surface of the inner plate 11c to restrict its own removal. The locking lever 61 can be securely held in the insertion position. In this embodiment, the other end 10j2 of the torsion coil spring 10j also functions as the removal restricting portion 61m.

  Further, the position at which the locking lever 61 is in contact with or close to the reference line portion z engaged with the one side edge 10s of the opening 10 and the inner surface of the outer plate 11a which is a flat surface and the other side edge 10t of the opening 10 is provided. The outer peripheral surface 10y is moved while maintaining the rotation, and the rotation is guided at the two points of the inner surface of the outer plate 11a and the opening edge 11t of the inner plate 11c with the reference line part z as a fulcrum. Even if it does not have, smooth rotation operation | movement is realizable.

  More specifically, the lock mechanism 61 is configured between the lock lever 61 and the drawers 2, 3, 4, which are actuating bodies, and the lock claws 61 a, 61 b, outward from the lock lever 61, 61c is projected, and the lock claws 61a, 61b, 61c are projected and retracted from the notches 10a, 10b, 10c which are openings provided in the inner plate 10c in accordance with the forward / reverse rotation of the locking lever 61 at the storage position, It is configured to lock the operation by engaging with the drawers 2, 3 and 4 when protruding, and it is a member that receives impact, but it does not have a fragile bearing structure, so it can be made of resin Reliability and durability can be ensured.

  Further, a restricting portion 61d is provided toward the outside of the locking lever 61, and the restricting portion 61d is abutted against the inner plate 10c to restrict the rotation of the locking lever 61 in the direction in which the lock claws 61a, 61b, 61c are retracted. Therefore, an appropriate operating range can be given to the locking lever 61 with a simple structure.

  As described above, since the locking lever 61 can secure strength and durability even if it is made of resin, resin is used in this embodiment, and the lock claws 61a, 61b, 61c, the restricting portion 61d, and the removal portion are removed. The regulation part 61m etc. can be made in various ways that cannot be realized with sheet metal because of its freedom in molding, etc., and can also be used for different specifications (height differences) of drawers 2, 3 and 4 Can also be pursued effectively. And since it is resin, the locking lever 61 can be reduced in weight and handled easily, and when the locking portion 63 is unlocked, the locking lever 61 can be moved to the unlocking position only by the elasticity of the torsion coil spring 61j. The operation is also light and smooth.

  Therefore, the support structure for the rotating body is extremely useful as a drawer device having the locking lever 61 as described above, and besides this, it is suitably used as a rotating body support structure for storage furniture including various rotating bodies. be able to.

  For example, it can be applied to support the rotating body of furniture configured to lock and unlock by rotating a rotating body with a wide drawer horizontally, or a shaft such as a door of a building or a furniture door can be used as a rotating body. The present invention can be applied to various uses as long as it rotates slowly.

  As mentioned above, although one Embodiment of this invention was described, the structure of each part is not limited to the example of illustration, A various deformation | transformation is possible in the range which does not deviate from the meaning of this invention.
