  For example, in the case of Patent Literature 1, when a hollow portion is provided on both sides of a projecting fence provided at the window of a house and both wings of a slide fence formed in a U-shape by providing a hollow portion are retractable and the fence is pulled out. The bellows-type telescopic floorboard is expanded. However, in this case, the drawer length is within the range of the length of the fences on both sides, and since the floorboard has a bellows structure, it is inconvenient to use and cannot be guaranteed in strength.

  In the case of Patent Document 2, casters are attached to a storage box formed of a box, and the storage box is pulled out from under the floor when necessary. A floor plate is provided on the upper surface of the box so that it can be used as a drawer-type edge. However, since casters are used, the ground in the drawer area is hardly leveled or concrete is not paved, so there is no stability, the usability is poor as a pull-out rim, and the area can not plant grass or flowers. There is.

  An object of the present invention is to provide a retractable garden deck that can be used by pulling out the garden deck from under the floor to the front of the garden when necessary. The support mechanism of the present invention can be applied not only to the garden deck but also to an office cabinet or a cupboard using a heavy drawer shelf.

Therefore, the cantilever support mechanism of the drawer according to the present invention has the following features.
(1) A drawer body, a storage section of the drawer body, a T-shaped rail fixed to the storage section, a guide door roller fixed on the T-shaped rail, and the T-shaped rail below the drawer body. A sliding door wheel fixed facing and running on the upper surface of the T-shaped rail, a hanging door wheel fixed facing the T-shaped rail below the drawer and running on the lower surface on both sides of the T-shaped rail, A first feature is that it is provided with a guide rail fixed to a lower portion and for guiding the guide door roller.
(2) A second feature of the cantilever support mechanism for a drawer according to the first aspect is that the drawer is a garden deck.
(3) The third feature of the cantilever support mechanism for a drawer according to claim 1 or claim 2 is that a stop means for any one of a guide door roller, a slide door roller, and a suspension door roller is provided.
(4) In the cantilever support mechanism for a drawer body according to claim 3, the stop means of any of the guide door roller, the slide door roller, and the suspension door roller is provided with a protrusion fixed on a T-shaped rail and the drawer side. The fourth feature is that the projection is fixed to the projection.
(5) The fifth feature of the cantilever support mechanism for a drawer according to the third aspect is that the stop means for any one of the guide door roller, the slide door roller, and the suspension door roller comprises a limit switch.
(6) The sixth feature of the cantilever support mechanism for a drawer according to any one of the first to fifth aspects is that the folding support for supporting the drawer is provided.

  In the cantilever support mechanism for a drawer according to the present invention, in the configuration of the above (1), the “cantilever support mechanism for the drawer” is replaced by a “support mechanism for a storage shelf housed in a cabinet”, a “T-shaped If "rail" is read as "rail laid on the floor in the cabinet" or the like, it can be applied to a heavy drawer shelf such as an office cabinet or a cupboard.

ADVANTAGE OF THE INVENTION According to the cantilever support mechanism of the drawer body which concerns on this invention, it has the following outstanding effects.
(1) When the load of the drawer is applied to the T-shaped rail, the force for causing the T-shaped rail is reduced, and the force for firmly connecting the T-shaped rail to the base can be reduced.
(2) By providing a gap by separating a plurality of door rollers, the bending moment for the drawer and the T-shaped rail can be greatly reduced while utilizing the weight of the drawer, so that the frame of the drawer and the T-shaped rail can be used. Can be made smaller, and weight reduction can be realized.

  For example, in the case of the slide-type garden deck 100 shown in FIG. 2, when the load of the garden deck 100 is applied to the T-shaped rail 6, the effect of pulling out the T-shaped rail 6 is reduced. The force for firmly connecting the T-shaped rail 6 and the base fixing member 36 can be reduced. Furthermore, by providing a plurality of door rollers (guide door roller 7, slide door roller 8, suspension door roller 9) and providing a gap, the bending moment for the garden deck 100 and the T-shaped rail 6 is greatly reduced while utilizing its own weight. Therefore, the size of the frame 2 and the T-shaped rail 6 of the garden deck 100 can be reduced, and the weight can be reduced.

  When this garden deck 100 is used, it is hidden in the storage portion 15 and only the front surface 11 of the frame 2 is exposed, so that the garden can be used freely and the aesthetic appearance is not spoiled. After the drawer, even if the garden deck 100 is exposed, the T-shaped rail 6, the guide door roller 7, the slide door roller 8, the suspension door roller 9, etc., which cantileverly support the garden deck 100, are hidden in the storage section 15 below the floor to the outside. Because it is not exposed, it is free to plant flowers in the garden.

  As shown in FIGS. 1 and 2, a cantilever support mechanism 1 for a garden deck according to a first embodiment of the present invention includes a garden deck 100 that is used by being pulled out from a storage section 15 under a house floor when necessary. A guide door roller 7 provided on two T-shaped rails 6 laid on a concrete fixing member 36 buried in a floor base surface of the portion 15, a V-shaped rail 10 provided on the lower surface of the frame 2 of the garden deck 100, and a slide. A door roller 8, a hanging door roller 9, and attachment means for these are provided. The garden deck 100, which is a drawer, is made of wooden or synthetic resin, and has a rectangular frame 2 mounted around plate rows arranged at predetermined intervals. A guide door roller 7 attached to the base end of the T-shaped rail 6 engages with the V-shaped rail 10 to roll, a sliding door roller 8 rolls on the T-shaped rail 6, and a hanging door roller 9 is a T-shaped rail. 6, the garden deck 100 can smoothly slide when being pulled out and stored. When the garden deck 100 is pulled out, it is cantilevered by the guide door roller 7, the slide door roller 8, and the suspension door roller 9. Here, the above-mentioned base end of the T-shaped rail 6 is the end of the T-shaped rail 6 on the house outdoor side (that is, the left side in FIG. 2), and the end of the T-shaped rail 6 is the T-shaped rail 6 2 (ie, the right end in FIG. 2). The guide door roller 7 is disposed near the base end of the T-shaped rail 6, the slide door roller 8 is disposed further away from the guide door roller 7 on the terminal end side, and the suspension door roller 9 is further disposed than the slide door roller 8. It is arranged apart from the terminal end.

  The T-shaped rail 6 may be a T-shaped rail having a flat top surface. In the present embodiment, the H-shaped steel is rotated so that the upper portion forms a T-shape and the lower portion forms an inverted T-shape. The U-shaped flat bottom surface was fixed to the fixing member 36 with the anchor bolt 16. At this time, the T-shaped rail 6 is disposed at a position corresponding to the direction in which the frame 2 of the garden deck 100 is pulled out. Instead of the H-shaped steel, a T-shaped steel may be used in which the top is a flat surface and the legs are vertically suspended from the flat surface.

  As shown in FIG. 3, the number of door rollers that cantileverly hold the garden deck 100 is configured by three. First, as shown in FIGS. 3 and 4, the guide door roller 7 is opposed to the V-shaped rail 10 attached to the lower surface of the frame 2 at a position several ten cm from the base end on the T-shaped rail 6. It is fixed. At this time, in order to adjust the height with respect to another door roller, a portion above the bottom flat surface of the T-shaped rail 6 at a position where the guide door roller 6 is fixed is cut. The guide door roller 7 is provided with a roller body 31 having a V-shaped groove in the center of the guide door roller housing, and engages with the V-shaped rails 10 that are stretched over the entire area of the lower surface of the frame 2 in the pull-out direction. Thus, the garden deck 100 is smoothly slid, and a load downward of the garden deck 100 is supported.

  As shown in FIGS. 3 and 5, the sliding door roller 8 is provided with a roller body 32 in a sliding door roller housing, and at a position where the roller body 32 can contact the T-shaped rail 6 on the lower surface of the frame 2 in the pulling-out direction of the garden deck 100. When the garden deck 100 is pulled out to the outside of the house as much as possible, it is arranged so as to be located several tens of centimeters from the position of the guide door roller 7 in the house. When the sliding door roller 8 runs while rolling on the T-shaped rail 6, the garden deck 100 is smoothly slid and the downward load of the garden deck 100 is supported.

  When the garden deck 100 is pulled out, as shown in FIG. 3, the protrusion 13 for the stopper of the stopping means provided on the lower surface of the frame 2 immediately before the pulling-out direction of the sliding door roller 8 is separated from the guide door roller 7 toward the house side. As a result, the slide door roller 8 stops at a position where the stopper protrusions 12 of the stopping means provided on the T-shaped rail 6 abut against each other. The maximum drawer length of the garden deck 100 is determined at this position. As described above, in the first embodiment, the stopping means of the sliding door roller 8 is provided to stop the garden deck 100 at the maximum length when the garden deck 100 is pulled out. The sliding door 8 can be stopped at an appropriate position by moving the positions of the stopper projections 12 and 13, and the stopping means may be provided on the guide door 7 and the hanging door 9.

  As shown in FIGS. 3 and 6, each of the hanging door rollers 9 is attached to the lower surface of the frame 2 in the pulling-out direction of the garden deck 100, and the lower surface on both sides of the flat surface of the top of the T-shaped rail 6 is formed by a pair of opposing surfaces. It is configured to be gripped by a roller body 33. Therefore, the hanging door roller 9 engages with the lower surface of the top flat surface of the T-shaped rail 6 and runs while rolling, so that the garden deck 100 slides smoothly and the roller body 33 is moved to the T-shaped rail 6. The engagement supports the upward load of the garden deck 100. In the first embodiment, a pair of roller bodies 33 for gripping the lower surfaces on both sides of the top flat surface of the T-shaped rail 6 are provided in the pull-out direction, and a total of four roller bodies 33 are provided in the hanging door housing 14. Is provided.

  As shown in FIGS. 2 and 7, the folding strut 3 is stored at the tip of the garden deck 100, and the folding strut 3 is erected in a state where the garden deck 100 is pulled out and is buried in the ground. The garden deck 100 is supported by being brought into contact with the table 4. Further, as shown in FIGS. 1 and 2, a plurality of rod insertion holes 17 for inserting the rods 5 for fixing the garden deck 100 at predetermined positions are provided at predetermined positions on the indoor floor surface of the house and on the upper surface of the garden deck 100. The rod 5 can be inserted and held so that the provided and pulled out garden deck 100 does not move at a predetermined position.

  With the configuration described above, the guide deck 7 and the sliding door 8 support the load of the garden deck 100 when the garden deck 100 is pulled out. After a certain length of the drawer, a rotational moment about the guide door roller 7 is applied to the suspension door roller 9 to try to lift the T-shaped rail 6 upward. And the upward load of the garden deck 100 is supported. Further, the guide door roller 7 and the slide door roller 8 to which a downward load acts on the garden deck 100 act so as to hold down the T-shaped rail 6 and support it. Therefore, the three door rollers arranged along the T-shaped rail 6 effectively act when the garden deck 100 is pulled out, and can slide smoothly while supporting the load of the garden deck 100.

  Next, the operation principle of the cantilever support mechanism 1 of the garden deck according to the first embodiment of the present invention will be described. FIG. 8 shows the positional relationship of each door wheel when the garden deck 100 is pushed in to the maximum (that is, when the garden deck 100 is completely stored). In this state, the load of the garden deck 100 is supported by the guide door roller 7 and the slide door roller 8, and the load of the garden deck 100 does not act on the suspension door roller 9.

  FIG. 9A shows the positional relationship of the door roller when the garden deck 100 is pulled out to the maximum in the cantilever support mechanism 1 of the garden deck 100 shown in FIG. 8, and FIG. And the rotational moment applied to the T-shaped rail 6. The guide door roller 7 is disposed on the T-shaped rail 6, and the slide door roller 8 runs on the T-shaped rail 6. Thus, as shown in FIG. 9B, the downward load acting on the garden deck 100 acts on the T-shaped rail 6, so that the upward force for causing the T-shaped rail 6 is reduced. Thus, the force for firmly connecting the T-shaped rail 6 and the base (fixed member 36 under the floor) to which the T-shaped rail 6 is fixed can be reduced. Further, by providing a gap between the sections A, B and C by separating the door cars, the bending moment for the garden deck 100 and the bending moment for the T-shaped rail 6 are greatly reduced while utilizing the own weight. it can. That is, as shown in FIG. 9B, the bending moment for the garden deck 100, the bending moment for the T-shaped rail 6, and the moment for causing the entire T-shaped rail 6 to be reduced can be reduced. The members of the frame 2 and the T-shaped rail 6 can be made smaller, and the weight can be reduced.

  FIG. 10 (a) uses only two guide door rollers 7 and suspension door rollers 9, arranges the guide door roller 7 on the T-shaped rail 6, and terminates the section A several tens of cm from the base end of the T-shaped rail 6. The principle of operation when taken on the part side is shown. In this case, as shown in FIG. 10 (b), the fulcrum that tries to cause the entire T-shaped rail 6 becomes two points, the point D and the point E, and the force applied to one point is dispersed and relaxed. You. Further, by placing the guide door roller 7 on the T-shaped rail 6, the force for causing the T-shaped rail 6 is further reduced, and the force for firmly connecting the T-shaped rail 6 and the fixing member 36 is reduced. . However, since it is a two-point support mechanism at points D and E, the bending moment for the T-shaped rail 6 itself is larger than that of the three-point support cantilever support mechanism 1 of the first embodiment.

  FIG. 11A shows an operation principle when only two guide door rollers 7 and suspension door rollers 9 are used and the guide door roller 7 is not disposed on the T-shaped rail 6. In this case, as shown in FIG. 11 (b), a very large force acts on the point D as a fulcrum to cause the entire T-shaped rail 6 to act. Needs to be very large, so that the means for fixing the T-shaped rail 6 to the base (fixing member 36) and the T-shaped rail 6 itself must be very firm.

  It should be noted that the garden deck 100 can be installed in a space where sufficient members can be provided, or when a solid member can be used, using a cantilever support mechanism as shown in FIGS. 10 and 11. Further, when applied to a larger stage or the like, the number of sliding door rollers 8 and hanging door rollers 9 may be increased in the required number in the section B shown in FIG. 9A.

  The operating principle of the present invention described with reference to FIGS. 8 to 11 is basically the same in the second embodiment and the third embodiment described below. The invention can be realized.

  The basic structure of the cantilever support mechanism 1a of the sliding gate according to the second embodiment of the present invention is the same as that of the first embodiment. As shown in FIGS.

The gate 100a, which is a drawer body, is made of wooden or synthetic resin, and has a rectangular frame 2a mounted around a flat plate array arranged at predetermined intervals. The guide door roller 7a attached to the base end of the T-shaped rail 6a engages with the V-shaped rail 10a and rolls, the sliding door roller 8a rolls on the T-shaped rail 6a, and the suspension door roller 9a is a T-shaped rail. By engaging and rolling with 6a, the gate 100a can perform a smooth sliding operation at the time of pulling out and storing. When the gate 100a is pulled out, the gate 100a is cantilevered by the guide door 7a, the slide door 8a, and the suspension door 9a. Here, the base end of the T-shaped rail 6a is the end of the T-shaped rail 6a laid on the fixing member 36a on the side where the gate 100a is pulled out (that is, the left side in FIG. 13). The terminating end of the rail 6a is defined as the end of the T-shaped rail 6a laid on the fixing member 36a on the storage section 15a side (that is, the right side in FIG. 2). The guide door roller 7a is disposed near the base end of the T-shaped rail 6a, the slide door roller 8a is disposed further away from the guide door roller 7a on the terminal side, and the suspension door roller 9a is further disposed than the slide door roller 8a. It is arranged apart from the terminal end.

  The T-shaped rail 6a may be a T-shaped rail having a flat top surface. In this embodiment, the H-shaped steel is rotated so that the upper portion forms a T-shape and the lower portion forms an inverted T-shape. The U-shaped bottom flat surface was fixed to a concrete fixing member 36a buried in the ground of the storage portion 15a of the gate 100a with an anchor bolt 16a. At this time, the T-shaped rail 6a is disposed at a position corresponding to the lower surface of the frame 2a, which is the direction in which the gate 100a is pulled out. Instead of the H-shaped steel, a T-shaped steel having a flat top surface and a leg portion extending downward from the flat surface may be used.

  As shown in FIGS. 14 and 15, as shown in the first embodiment, the number of the door wheels that cantileverly hold the gate 100 a is basically three. First, the guide door roller 7a is fixedly mounted at a position close to the terminal end by several tens of cm from the base end on the T-shaped rail 6a so as to face the V-shaped rail 10a attached to the lower surface of the frame 2a. At this time, in order to adjust the height with respect to another door roller, a portion above the center of the T-shaped rail 6a where the guide door roller 6a is fixed is cut. The guide door roller 7a is provided with a roller body 31a having a V-shaped groove at the center in the guide door roller housing, and is engaged with V-shaped rails 10a which are stretched over the entire lower surface of the frame 2a in the pull-out direction. In addition, it guides the smooth sliding of the gate 100a and supports the downward load of the gate 100a. In the second embodiment, the electric drive motor 25a is installed inside the gate 100a, and the output shaft of the electric drive motor 25a is connected to the roller shaft of the guide door wheel 7a by a set of bevel gears 30a. The roller shaft is formed so as to rotate integrally with the roller body 31a. When the in / out movable switch 20a provided on the gate post 26a and electrically connected to the electric drive motor 25a is turned on, the electric drive motor 25a is driven, and the rotation output is transmitted to the guide door wheel 7a via the bevel gear 30a, and the guide The door roller 7a rotates. Therefore, the gate 100a also slides smoothly in conjunction with it. The electric section drive motor 25a may be driven and controlled by a remote controller. Further, the sliding door 8a and the hanging door 9a other than the guide door 7a may be electrically controlled.

  In the cantilever support mechanism 1a of the gate according to the second embodiment, as shown in FIG. 14, a pair of limit switches is provided between the pair of upper fixed guide door rollers 18a. A storage limit switch 22a is provided at an appropriate position on the right side of the left upper fixed guide door roller 18a, and a drawer limit switch 19a is provided at an appropriate position on the left side of the right upper fixed guide door roller 18a. When the gate 100a is pulled out, the sensor 40a of the draw-out limit switch 19a comes into contact with the sensor projection 27a provided on the upper surface of the frame 2a, and the stop position of the gate 100a is detected. 25a is automatically stopped. When the pulled-out gate 100a is stored, the sensor 41a of the storage limit switch 22a comes into contact with the sensor projection 27a to detect the stop position of the gate 100a, and the electric drive motor 25a is automatically stopped.

  As shown in FIGS. 14 and 16, the sliding door roller 8a has a roller body 32a in the sliding door roller housing, and is mounted on the lower surface of the frame 2a of the gate 100a at a position where it can contact the T-shaped rail 6a. When the gate 100a is pulled out to the proximal end side of the T-shaped rail 6a to the maximum, the gate 100a is arranged so as to be located several ten cm closer to the end than the position of the guide door roller 7a. When the sliding door roller 8a runs while rolling on the T-shaped rail 6a, the gate 100a is smoothly slid and the load below the gate 100a is supported.

  As shown in FIGS. 14 and 17, the hanging door roller 9a is attached to the lower surface of the frame 2a of the gate 100a, and the lower surface on both sides of the flat surface at the top of the T-shaped rail 6a is gripped by the opposing roller body 33a. It has become. Therefore, the hanging door roller 9a engages with the lower surface of the flat top surface of the T-shaped rail 6a and runs while rolling, so that the gate 100a slides smoothly and the roller body 33a engages with the T-shaped rail 6a. The combination supports the upward load of the gate 100a. In the second embodiment, a pair of roller bodies 33a for gripping the lower surface on both sides of the top flat surface of the T-shaped rail 6a are provided in the pull-out direction. 14a.
