Definitions

  • the present invention relates to a door closing device for a sliding door used in a variety of storage furniture such as cupboards, bookcases and showcases and the like in which an excellent door closing motion is produced by, when the sliding door is moved closer to the door closing side end part of the sliding door in particular, the pulling of the sliding door forcibly nearer to the door closing side end part and, at the completion of the closing of the door, the appropriate deceleration of the speed of the sliding door.
  • Sliding door devices of the prior art include the device disclosed in Japanese Laid-Open Patent Application No. 2002-138739.
  • most sliding doors mounted in various storage furniture such as cupboards, bookcases and showcases comprise a glass door.
  • These sliding doors may be of a very simple structure in which, provided the front facade of the storage furniture is not large, guide rails are formed in positions at the top and bottom of the front facade and the upper and lower end parts of a glass plate are inserted in these guide rails.
  • Exclusive furniture demand that the opening and closing motion of the sliding door be both dignified and elegant.
  • large furniture also have large sliding doors and, in addition, because the weight of the doors themselves is very heavy, it is difficult to produce an opening and closing motion using the sliding door of the structure of the prior art as described above that is both dignified and elegant.
  • the present invention provides a door closing device for a sliding door in which a hook member is turnably mounted on a slide member that slides along an appropriate region in a casing mounted in an end part position of a guide rail; the slide member is urged to the door closing side by way of an elastic member; and a guide moving body that moves along a guide rail is moved along the sliding region of the slide member in the direction of door closing from a state in which it is engaged by the hook member, by a resistance force produced by a buffer member that reduces the elastic force of said elastic member, whereby an excellent door closing motion can be produced by the forcible pulling of the sliding door nearer to the door closing side end part and, during the completion of the door closing, the appropriate deceleration of the speed of the sliding door. Furthermore, the space required for the assembly of the door closing device in the sliding door device can be minimized by the compacting of the door closing device and the direct assembly
  • the smooth door closing motion of the sliding door can be achieved by the method for affixing the abovementioned door closing device of the sliding door.
  • This refers to the fact that the hook member is slidably provided due to a pivotal connection between the buffer member and the hook member.
  • the force at which the slide member moves along the casing in the direction of closing of the door is produced by the elastic force of the elastic member, because of the provision of the buffer member for reducing this elastic force, the sliding door can be moved in the direction of closing of the door by the guide moving body at a force that is equivalent to the resistance force of the buffer member deducted from the elastic force of the elastic member and, accordingly, a very smooth, stable and excellent door closing motion can be performed.
  • a door closing device for a sliding door comprises a slide member; a hook member comprising a turning base part pivotally connected to the slide member, an engaged piece, an abutted piece and an engage part that is projected upward by the turning motion of the turning base part; an elastic member that urges said slide member elastically in the door closing side direction; a buffer member that generates a resistance force that reduces the elastic force of said elastic member; a main guide part in which the slide member, hook member, elastic member and buffer member are mounted and in which the slide member is guided in the horizontal direction; a casing mounted on a guide rail and having an engaged surface part formed in a position of said main guide part more toward the door opening; and a guide member provided in a guide moving body that moves along the guide rail and having a locking part that engages with the engaged piece and that abuts against the abutted piece, the locking part being formed in the tip end of an arm-shaped part that extends in the direction of movement, wherein the hook member is formed so that
  • an excellent door closing motion can be produced by, when the sliding door is moved closer to the door closing side end part of the sliding door, the forcible pulling of the sliding door nearer to the door closing side end part and, at the completion of the closing of the door, the appropriate deceleration of the speed of the sliding door. Furthermore, the space required for the assembly of the door closing device in the sliding door device can be minimized by the compacting of the door closing device and the direct assembly thereof in the guide rail of the sliding door.
  • the hook member in which the engaged piece and abutted piece are formed is swingable with respect to the slide member and, in addition, the engage part is designed to project upward by the turning motion of the turning base part.
  • the hook member is formed so that the slide member swings only at the end part position at the door opening side and so that the engage part is engagable with the engaged surface part. Accordingly, in the door closing motion, a temporary stopped state is formed in the initial state in which the hook member is in a stable state at the door opening side. That is to say, when the swing motion of the hook member is implemented little sway thereof occurs in the left and right directions whereby, accordingly, the likelihood of a breakdown thereof occurring is very small.
  • the engagement that takes place when the locking part of the guide moving body attempts to engage the hook member is smooth and the slide member and hook member are moved in the direction of closing of the door by the elastic member
  • the resistance force of the buffer member acts on the elastic member at this time to reduce the elastic force thereof
  • the slide member along which the guide moving body is moved and the hook member can be moved at the appropriate smooth speed in the casing.
  • the slide member and hook member move in the casing along the longitudinal direction of the casing, and the movement direction thereof is the same as the direction of movement of the guide moving body in the guide rail.
  • the casing of the present invention can be mounted in the end part in the longitudinal direction for the guide moving body and, as a result, an essential integration with the guide rail and simplification of the mounting of the device of the present invention and minimizing of the space in the position of mounting thereof can be achieved.
  • a door closing device for a sliding door is designed, based on the abovementioned configuration, such that the engage part and the engaged surface part are formed in a circular arc-shaped convex face part and a circular arc-shaped concave face part that turn about a pivotally-connected part, whereby, when the hook member moves from the main body part to the position of the engaged surface part to afford the engagement of the engage part and the engaged surface part, the turning motion of the hook member can be performed very smoothly.
  • a door closing device for a sliding door is designed, based on the abovementioned configuration, such that a rack part is formed in the slide member; and the buffer member comprises a tooth gear part that meshes with the rack part and that generates a resistance force in response to the movement of the slide member in the door closing side direction produced by the elastic, whereby the deceleration of the sliding door can be performed simply and satisfactorily.
  • a door closing device for a sliding door is designed, based on the abovementioned configuration, such that a slide member operating piece and hook operating piece that project to the exterior of the casing are formed in the slide member and hook member respectively, whereby, even if, due to inexact motion, only the hook member is within the casing in a state in which the locking part of the guide moving body is not engaged by the hook member, the hook member can be projected to the exterior of the casing by the slide member operating piece and the hook operating piece.
  • the present invention is principally configured from door closing device component parts comprising, for example, a slide member 1, a hook member 2, an elastic member 3, a buffer member 4 and a casing A fixed to a guide rail side, and a guide moving body B mounted on a sliding door 18 side.

  • the guide protruding piece 1d constitutes the region that slides along a later-described main guide part 6 of the casing A. Furthermore, a later-described elastic member connection part 1e to which the end part of the elastic member 3 is fastened is formed in the lower part of the abovementioned guide protruding piece 1d. In addition, a slide member operating piece 1f is formed in such a way as to project downward from the position of the guide protruding piece 1d. In addition, a later-described slide-regulating protrusion 1g that engages with a slide-regulating part formed in the casing A side is formed in the abovementioned slide main body part 1a. The slide-regulating protrusion 1g, which is formed in the end part toward the door closing side in the longitudinal direction of the slide member 1, is formed to protrude in a direction orthogonal to the longitudinal direction of the slide member 1.
  • a projecting part 1h that protrudes upward is formed in the door opening side end part of the slide member 1 and, by the abutting of the tip end of the projecting part 1h against the later-described hook member 2, serves the role of regulating the range of swing of the hook member 2.
  • the door closing side refers to the direction in which the sliding door 18 is moved when closed which, in Figure 1A, is the direction from the left side to the right side.
  • the door opening side in Figure 1A is the direction from the right side to the left side.
  • the side to the right of the casing A is the door closing side and the side to the left is the door opening side.

  • the engaged piece 2b 1 as shown in Figure 5A and Figure 5B, is formed to a dimension that is less in the height direction than the abutted piece 2b 2 .
  • the shape between the engaged piece 2b 1 and abutted piece 2b 2 describes an approximately U-shaped recess part 2b 3 , and a later-described locking part 15b of the guide moving body B can be inserted in this recess part 2b 3 .

  • the hook operating piece 2e projects to the exterior of the casing A together with the abovementioned slide member operating piece 1f so that an operation to forcibly move the slide member 1 and hook member 2 to the exterior of the casing A can be performed (see Figure 1A).
  • a locking protrusion piece 2f is formed in the position of the apex part of the abovementioned turning base part 2a in such a way as to describe a right angle with the width direction of the hook part 2b.
  • the locking protrusion piece 2f moves so that, when the hook member 2 moves along the later-described main guide part 6 together with the slide member 1, the abovementioned locking protrusion piece 2f abuts the main guide part 6.
  • the casing A which is divided into two halves, is configured from a first casing part A 1 and a second casing part A 2 .
