Definitions

  • This invention relates to a cabinet with an upswing door adapted to be swung up to become open and placed at rest on the top of the cabinet main body.
  • Japanese Patent Application Laid-Open No. 8-143507 discloses a cabinet with an upswing door that provides a remarkable improvement to conventional cabinets of the type under consideration.
  • a slide rail assembly has to be arranged on the rear surface of the door in order to allow the door to be swung and placed at rest on the top of the cabinet main body.
  • the above patent document proposes a cabinet main body having a specific configuration in order to eliminate the need of arranging such a slide rail assembly and make the operation of opening and closing the door an easy one by using in combination a simple and specifically designed hinge unit and a conventional door damper unit.
  • FIGS. 15 through 18 an end of hinge 1c is rigidly fitted to the front edge 1b of the top wall 1a of the cabinet main body while the other end of the hinge 1c is secured to inner rail 1f of slide rail assembly 1e buried in the rear side of the upswing door 1d.
  • the door 1d can be swung up around pin 1g of the hinge 1c to become open by pulling up the lower end of the door 1d and then placed at rest on the top wall 1a of the cabinet main body as shown in FIG. 17 by pushing the door 1d as outer rail 1 h of the slide rail assembly 1e slides relative to the inner rail 1f.
  • door damper unit A comprises a fitting case 2 to be rigidly secured to the inner surface 1i of one of the lateral walls of the cabinet main body typically by means of screws 2a and a spring holder/slider 4 that is vertically movable relative to the fitting case 2 and urged downward by a given number of compression springs 3.
  • the fitting case 2 includes a reinforcement cover plate 2b secured to inner surface 1i of the lateral wall and a fitting case main body 2c arranged within the cover plate 2b.
  • reference symbol 2d denotes fitting holes bored in the reinforcement cover plate 2b for receiving a screw 2a
  • reference symbol 2e denotes through holes bored through the top wall 2f of the reinforcement cover plate 2b
  • reference symbol 2g denotes threaded fitting holes bored through the top wall 2h of the fitting case main body 2c.
  • reference symbol 2i denotes lateral walls of the reinforcement cover plate 2b extending downward from the opposite ends of the top wall 2f along the fitting wall 2j thereof and reference symbol 2k denotes lateral walls of the fitting case main body 2c also extending downward from the opposite ends of the top wall 2h along the front wall 2m thereof.
  • a containing room 2n for vertically movably containing the spring holder/slider 4 is defined within the fitting case main body 2c.
  • a pair of through holes 2p are bored through the respective lateral walls 2i of the reinforcement cover plate 2b and another pair of through holes 2q are bored through the respective lateral walls 2k of the fitting case main body 2c, through which a spring stopper pin 2r is arranged and held in abutment with the upper ends of the compression springs 3.
  • the spring holder/slider 4 has a box like profile with a front wall 4a, a rear wall 4b and oppositely disposed lateral walls 4c. Thus, it is open at the top.
  • the internal space of the spring holder/slider 4 is divided into three spring containing rooms 4e as defined by the paired lateral walls 4d and a pair of partition walls 4e running in parallel with the lateral walls 4d.
  • the three compression springs 3 contained in the respective rooms are held at the upper end thereof in abutment with the spring stopper pin 2r and downwardly urges at the lower ends thereof the pressure receiving pin 4f rigidly secured to the lateral walls 4c of the spring holder/slider 4.
  • the spring holder/slider 4 is adapted to move upward to compress the compression springs 3 and downward to expand the compression springs 3 as its lateral walls 4c slide along the inner corresponding surfaces of the lateral walls 2k of the main body 2c of the fitting case 2.
  • the lateral walls 2k of the main body 2c of the fitting case 2 are provided on the inner surfaces thereof with respective vertical guide grooves 2s so that the spring holder/slider 4 may be vertically moved with its lateral walls 4c guided by the grooves 2s. Therefore, as the spring holder/slider is moved downward, it eventually hit the stoppers 2t formed by the lower ends of the guide grooves 2s so that its downward movement is limited by the stoppers 2t. Under this condition, the resilient force of the compression springs does not affect the member linked to them as will be described hereinafter.
  • a link arm 5 is fitted at the upper end thereof to the spring holder/slider 4 by means of a pin 5a so that it may pivot on the pin 5a.
  • a rotary arm 6 is rotatably fitted to a lower portion of the fitting case 2 by means of an arm shaft 6a and the lower end of the link arm 5 is linked to the base section 6b of the rotary arm 6 at a position near the arm shaft 6a by means of another pin 5b so that the link arm may pivot on the both pins 5a, 5b.
  • the arm section 6c of the rotary arm 6 is extending from the base section 6b thereof and fitted to the upswing door 1d by means of an arm holder 7 that is rigidly secured to the upswing door 1d and a pin 6d.
  • the pin 5a for anchoring the link arm 5a to the spring holder/slider 4 is received not by through holes but by downwardly open grooves 4g formed at a lower central parts of the front wall 4a and the rear wall 4b of the spring holder/slider 4 as shown in FIG. 18 so that the pin 5a may be vertically movable.
  • the rotary arm 6 has a gap 6e separating it into two wall portions to make it show a U-shaped cross section and the link arm 5a is inserted into the gap at the lower end thereof and secured to the base section 6b of the rotary arm 6 by means of the pin 5b to that it may pivot on the pin 5.
  • the arm section 6c and the arm holder 7 linked together by the pin 6d in a similar manner.
  • the arm shaft 6a is provided with a engaging projection 6f to be engagedly received in a corresponding engaging recess 6h formed in the shaft receiving hole 6h cut through the base section 6b of the rotary arm 6 in order to transmit the rotation motion of the rotary arm 6 to the arm shaft 6a. Then, the arm shaft 6a is coaxially secured to the rotary shaft 8a of the damper mechanism 8 arranged at a lower part of the fitting case 2.
  • the damper mechanism 8 exerts an effect of damping the closing or opening motion of the upswing door 1d by means of the viscous fluid (not shown) contained in the damper mechanism 8.
  • the illustrated damper mechanism 8 is already known. Referring to FIG. 18, it comprises, in addition to the above described rotary shaft 8a, a damper bearing section 8b arranged at the bottom of the fitting case main body 2c, a movable disk 8c movably fitted to the rotary shaft 8a, a fixed disk 8d arranged immovably vis-à-vis the movable disk 8c, a pair of O-rings 8e and 8f and a closure 8g for closing the damper mechanism 8 secured in position by means of screws (not shown) driven through the threaded holes bored through the reinforcement cover plate 2b.
  • the compression springs 3 are in a compressed state to exert their resilient force downwardly in FIG. 15 to the link arm 5. Therefore, the base section 6b of the rotary arm 6 is subjected to a rotary force trying to rotate it in the sense of arrow R1 in FIG. 15 so that the upswing door 1d is held to the closed state and would not be inadvertently opened.
  • damping effect of the damper mechanism 8 may be so arranged by using a one-way clutch or some other means (not shown) that the damping effect of the damper mechanism 8 becomes effective only when the door is closed. Then, the closing motion of the door will proceeds more slowly and smoothly than ever.
  • the damping effect of the damper mechanism 8 is effective both when the door is closed and when it is opened. Then, while the resilient force of the compression springs 3 may exert an effect of braking the door opening motion, the effect of the damping mechanism for encouraging the door opening motion can be maximized by appropriately adjusting it. Then, the use of a one-way clutch is not necessary.
  • the upswing door 1d is completely released from the damper mechanism so that the user can easily push the door 1d on the top wall 1a from the state of FIG. 16.
  • the spring holder/slider 4 is provided with the downwardly open grooves 4g that are relatively long and the pin 5a is located at the uppermost positions in the grooves 4g when the door 1d is in the state of FIG. 16.
  • the pin 5a gradually moves downward in the grooves 4g to allow the upswing door 1d to be pushed until it becomes completely at rest on the top wall 1a as shown in FIG. 17 because the outer rail 1i slides relative to the inner rail if.
  • the upswing door 1d With a cabinet with an upswing door having a configuration as described above, the upswing door 1d can be easily moved to open and placed at rest on the top wall 1a under the effect of the door damper unit A. It can also be closed softly from the rest position on the top wall 1a under the effect of the door damper unit A.
  • the upswing door 1d cannot be opened nor closed simply by swingably fitting the upswing door 1 to the to wall 1a of the cabinet main body by means of a hinge 1c but a costly slide rail assembly 1e has to be buried in the rear surface of the door 1d and the inner rail 1f of the slide rail assembly 1e has to be linked to the hinge 1c.
  • the slide rail assembly 1e is buried in the rear surface of the upswing door 1d, the latter has to be made very flat. In other words, an upswing door having a curved profile cannot be used for such a cabinet. Then, the cabinet main body 1 is required to show a simple rectangularly parallelepipedic profile having an opening 1j to be closed by the upswing door 1d as shown in FIGS. 15 through 17. Since the opening 1j is located at the front of the cabinet and its size is limited, the user may feel it inconvenient to access the inside of the cabinet.
  • an of the invention is to provide a cabinet with an upswing door, wherein the door is not simply suspended from the top wall of the cabinet main body when it is closed as in the case of the above described known cabinet but one or more than one of the walls of the cabinet main body is made to provide part of the opening of the cabinet and the closure of the opening of the cabinet is realized by sequentially linking a plurality of wall plates including the upswing door to the stationary part of the cabinet main body with a plurality of hinges and by using a simple metal arm unit for articulating the cabinet main body and the upswing door so that the plurality of wall plates can be placed at rest as they are folded one on the other on the top wall of the cabinet main body.
