Description

  The present invention relates to a foldable metal fitting suitable for placing a shelf board on furniture and temporarily placing an object, or adding an auxiliary top board to a table top board to widen the top board.

  When removing a serving plate from furniture, for example, a kitchen cupboard, if the necessary plate is stored at the back of the cupboard, remove the unnecessary plate stored in the foreground and place it on the cooking table. I had to put the dish in the back after putting it in a place like this. Necessary dishes taken out from the cupboard are placed on the cooking table, and unnecessary dishes placed on the cooking table or the like are returned to the cooking table. In other words, when taking out the dish stored in the back of the cupboard, carry the unnecessary dish in front to the cooking table, take out the dish in the back, carry it to the cooking table, and it is unnecessary that was placed on the cooking table It was necessary to move between the cupboard and the cooking table many times.

  In addition, when many dishes are made when cooking, the prepared many dishes are put on the cooking table, but there is no room for the cooking table and there is a problem with the place where the dishes are placed. The finished dishes can be taken to the dining room or living room, but the in-process dishes will be kept at hand and will continue as other dishes are cooked. Thus, when taking out tableware from a cupboard or making many dishes, it will be convenient if a shelf board can be installed in the cupboard.

  By the way, in recent houses and condominiums, people who cook in the kitchen can cook while watching TV in the living room, talking with people in the living room, or monitoring infants in the living room In addition, so-called face-to-face kitchens in which kitchen furniture such as a sink and a microwave oven are installed between the living room and the kitchen are increasing. In general, in a face-to-face kitchen, food cooked in the kitchen is placed at the end of the kitchen furniture, and people in the living room bring them to the living table for dining. However, in the morning hours when they are busy preparing for commuting and attending school, they want to dine near the kitchen furniture instead of going to the living table. If a shelf board can be installed in this face-to-face kitchen furniture, it will be convenient because the shelf board can be used as a table to eat.

  In addition, the table placed in the living room has legs installed on the top, and the size of the top is selected according to the number of family members and the size of the living room. However, at first, even if the table is suitable for two couples, if a child is born and the number of family members increases, or if the number of family members does not increase, there will be visitors. Small and difficult to use on the table. Therefore, we want to set up a table with a wide top plate in anticipation of an increasing number of family members and visitors, but placing a wide table with a wide top plate in a narrow living room will interfere with walking and cleaning the room. It is. In such a case, an auxiliary top plate may be added to the small top plate of the table to widen the top plate.

  If the shelf is foldably attached to the furniture or the auxiliary top plate is foldably attached to the table top, the shelf and auxiliary top can be folded down during normal times. Even in the room, these shelves and auxiliary top plates should not interfere with people walking or cleaning the room. For this reason, there have been many proposals for a table with a shelf board and a table with an auxiliary top board.

  To install a shelf on furniture or add an auxiliary top to the table top, attach folding brackets between the wall of the furniture and the shelf or between the top and the auxiliary top. It was foldable. The folding bracket can be used to easily place objects on furniture by raising a shelf or auxiliary top plate that has been tilted downward during normal times, so that furniture can be easily placed. Can also be used widely.

Conventionally, folding brackets for attaching a shelf board to furniture or attaching an auxiliary top board to a table have a plurality of levers (Japanese Utility Model Laid-Open Nos. 56-132944, 7-308229, 10- 10). 117856) and one having a long lever (Japanese Patent Laid-Open No. 11-318574). The one having a plurality of levers is such that one lever is attached to the wall or top plate of the furniture, and the other lever is attached to the shelf plate or auxiliary top plate. In addition, the one having a long lever is one in which one end of the lever is attached to the shelf and the other end is attached to the wall surface of the furniture, and the shelf is slidably attached to the wall surface. .
No. 56-132944 JP 7-308229 A Japanese Patent Laid-Open No. 10-117856 JP 11-318574 A

  Since conventional folding brackets use multiple levers and long levers, they are exposed on the side of the shelf and the auxiliary top plate, and even furniture and tables that are excellent in corner interior design look good. In addition to deteriorating the stored item, the stored item may hit these levers and damage the stored item when the stored item is taken in or out. Furthermore, conventional folding brackets are folded like a plurality of levers, or one lever and the shelf close to each other when the shelf or auxiliary top plate is raised or lowered. Become. At this time, if you can put your finger between the two levers or between the lever and the shelf, if you get hurt by pinching your finger, or if a heavy object is placed on the top or shelf, your finger will be severed. There was also a risk of doing.

  The present invention relates to a folding bracket comprising a movable piece attached to a shelf board of a furniture, an auxiliary top board of a table and the like, and a fixed piece attached to a wall surface of the furniture, a table top board, etc., and the movable piece is connected to a plate attachment surface. A surface is formed, and the connecting surface has a protruding portion on the fixed piece side, and the protruding portion has a long hole with a lower portion inclined to the fixed piece side. A locking portion that locks with a part of the fixed piece is formed below the protruding portion, and the fixed piece has a mounting surface that is fixed to furniture, a top plate, etc., and a shaft support surface that is connected to the movable piece. The connecting pin that is formed on the shaft support surface is inserted into the elongated hole, the movable piece and the fixed piece are rotatably connected, and the movable piece is connected to the moving piece. It is a foldable metal fitting characterized by being able to move a certain distance.

  The folding metal fitting of the present invention does not use a plurality of levers or long levers, so that it does not look good, the stored items are damaged by the levers, or a finger is sandwiched between levers that are folded like a bag. There is an unprecedented excellent effect that there is no.

  The folding metal fitting of the present invention comprises a movable piece attached to a shelf board or an auxiliary top plate of a table and a fixed piece attached to a side wall of furniture or a table top plate. The mounting surface for attaching the fixed piece to the furniture should be a suitable mounting surface depending on the shape of the mounting location.

  For example, for a kitchen furniture sink having a mounting portion only in the vertical direction, the mounting surface of the fixed piece is a vertical mounting surface having a surface to be mounted only in the vertical direction. Also, for items with stepped parts in the design, such as cupboards, the mounting surface of the fixed piece is the lower mounting surface that is attached to the lower surface of the stepped portion and the vertical mounting surface that is attached to the vertical surface of the stepped portion The two mounting surfaces. Furthermore, the attachment surface of the fixed piece for attaching the auxiliary top plate to the top plate of the table is only the lower attachment surface because the fixed piece is attached to the lower surface of the top plate.

  In the folding metal fitting of the present invention, the fixed piece and the movable piece are connected to each other while being moved by a certain distance and being rotatable. In order to move and rotate the fixed distance, a shaft supporting surface is formed on the fixed piece and a connecting pin is erected on the shaft supporting surface, and a connecting surface is formed on the movable piece and the length inclined to the connecting surface. A hole is drilled. The movable piece inserts a long hole into the connecting pin, and the long hole moves along the connecting pin.

  When the long hole of the movable piece is in use, that is, when the plate mounting surface to which the shelf board or auxiliary top plate is attached is in a horizontal state, the lower part of the long hole is inclined to the fixed piece side. When the connecting pin is not in use, that is, when the side plate and auxiliary top plate are vertical, the connecting pin is located at the lowermost end of the long hole (the position of the long hole when used). Even when the auxiliary top plate is raised to the uppermost horizontal position, the connecting pin is located at the lowermost end of the long hole. That is, the movable piece is rotated with respect to the connecting pin at the lowermost end of the elongated hole when the shelf board and the auxiliary top board are changed from the vertical state to the horizontal state.

  And when a shelf board or an auxiliary top plate falls by the dead weight of a shelf board or a top plate from the highest horizontal position, an elongate hole falls along a connection pin. At this time, since the lower part of the long hole is inclined to the fixed piece side, the shelf and the top plate at the uppermost position approach the fixed piece side, and there is no gap between the shelf and the furniture or between the auxiliary top and the top plate. To improve the appearance. In addition, the connecting pin is positioned at the top of the long hole, and the locking part of the movable piece is locked to the fixed piece, making it stable and easy to place heavy objects on a horizontal shelf or top plate. There is no such thing as dropping. The inclination angle of the elongated hole is preferably about 45 degrees or an acute angle.

  Hereinafter, the folding metal fitting of the present invention will be described based on the drawings. As shown in FIG. 5, the first embodiment is a foldable metal fitting that is suitable for mounting to furniture having a vertical mounting position, for example, a sink for kitchen furniture. A first embodiment will be described with reference to FIGS. FIG. 1 is a perspective view of the folding metal fitting of the present invention as viewed obliquely from below, FIG. 2 is a plan view thereof, FIG. 3 is a side view thereof, and FIGS. It is explanatory drawing until it lifts up one by one and makes it a use state.

  The folding metal fitting 1 of the first embodiment is composed of a movable piece 2 attached to the shelf board T and a fixed piece 3 attached to the furniture K.

  The movable piece 2 forms two surfaces bent at right angles, one surface being a plate attachment surface 4 attached to the lower surface of the shelf T, and the other surface being a connection surface 5 connected to the fixed piece 2. A plurality of screw insertion holes 6 are formed in the plate mounting surface 4. The connecting surface 5 protrudes toward the below-described vertical mounting surface 10 of the fixed piece 3, and the protruding portion is a protruding portion 7 that is connected to the fixed piece 2. 4D, when the plate mounting surface 4 is in a horizontal use state as shown in FIG. 4D, the lower portion is inclined to the vertical mounting surface side so that the lower part approaches the vertical mounting surface 10 of the fixed piece. A long hole 8 is formed. When the shelf plate T is used as shown in FIG. 4D, that is, when the plate mounting surface 4 of the movable piece 2 is in a horizontal state, the long hole is connected to the connecting pin 14 to be described later. When the shelf T is lowered as shown in FIG. 4A, ie, when the plate mounting surface 4 is vertical, the lowermost portion of the long hole 8 (It is the upper part in FIG. 4A) is a position where it abuts on the connecting pin of the fixed piece. A locking portion 9 that can be locked to a stopper 13 of a fixed piece to be described later is formed below the protruding portion 7. The locking portion 9 in the folding metal fitting of the first embodiment has a shape that allows the stopper to be matched so that it does not easily come off when locked with the stopper.

  The fixed piece 3 of the folding metal fitting of the first embodiment also forms two surfaces bent at right angles, with one surface being a vertical mounting surface 10 to be attached to a vertical mounting portion of the furniture K, and the other surface being the movable piece 2. The shaft support surface 11 is connected to the connection surface 5.

  A plurality of screw insertion holes 12... Are formed in the vertical mounting surface 10 of the fixed piece 3 and are movable when the shelf board T is in a horizontal state as shown in FIG. A stopper 13 is formed where the locking portion 9 of the piece 22 is located. The stopper 13 is formed by extending a part of the vertical mounting surface 10 of the fixed piece 3 and bending the extended part inward.

  The shaft support surface 11 of the fixed piece 3 is obtained by extending the horizontal upper portion of the vertical mounting surface 10 and bending it inward at a right angle with respect to the vertical mounting surface 10. That is, the vertical mounting surface 10 of the fixed piece 3 is bent laterally with respect to the shaft support surface 11. On the shaft support surface 11, a connecting pin 14 having a slightly smaller diameter than the lateral width of the long hole 8 is provided upright. As shown in FIG. 4D, the connecting pin 14 is positioned at the upper end of the elongated hole 8 of the movable piece 2 when the shelf board T is placed in a horizontal state as shown in FIG. Thus, when the shelf board T is lowered, the connecting pin 14 is erected so that it is located at the lower part of the long hole 8 (upper part in FIG. 4A). A flange 15 having a diameter larger than the width of the long hole 8 is formed at the top of the connecting pin 14 so that the connecting pin does not easily come out of the long hole when inserted into the long hole 8 of the movable piece 2. It has become.

  Next, attachment of the folding fitting of the first embodiment having the above-described configuration and its operating state will be described.

  As shown in FIG. 4D, the folding bracket 1 is first mounted on the plate mounting surface 4 of the movable piece 2 with the plate mounting surface 4 of the movable piece 2 and the vertical mounting surface 10 of the fixed piece 3 being perpendicular to each other. Attach the end of the plate T. As shown in FIG. 4D, when the shelf T is attached to the movable piece 2, the side surface of the shelf T and the attachment location of the furniture K are in close contact with each other when the plate attachment surface 4 is horizontal. In this state, a wood screw is screwed through the screw insertion hole 6 of the plate mounting surface 4. One folding bracket is attached near each end of the shelf.

  When the folding bracket 1 is attached to both ends of the shelf board T, the furniture K is mounted in a state where the plate mounting surface 4 of the movable piece 2 and the vertical mounting surface 10 of the fixed piece 3 are perpendicular to each other as shown in FIG. The fixed piece 3 of the folding bracket 1 is aligned at a predetermined position, and a wood screw is screwed into the screw insertion hole 12 of the vertical mounting surface 10 of the fixed piece 3 to fix the fixed piece 3 to the mounting surface of the furniture K.

  The raising and lowering of the shelf board T attached to the furniture K with the folding metal fitting 1 will be described.

FIG. 4A: A state in which the shelf board T is lowered, that is, a state before the shelf board T is used. At this time, the connecting pin 14 is located at the lowermost part of the elongated hole 8 (the upper part in FIG. 4A).
FIG. 4B: In order to form a shelf board on the furniture, the shelf board T is held up and lifted upward.
FIG. 4C: When the shelf board T is further lifted, the shelf board T becomes horizontal. At this time, the connecting pin 14 is still located at the lowermost part of the long hole 8.
FIG. 4D: When the shelf board T is in the horizontal state, the shelf board T is lowered in the horizontal state by its own weight. At this time, since the lower portion of the long hole 8 is inclined toward the furniture side, the long hole 8 slides along the connecting pin 14, and the movable piece 2 comes closer to the vertical mounting surface 10 of the fixed piece 3. When the connecting pin 14 reaches the uppermost portion of the long hole 8, the shelf board T also approaches the attachment position of the furniture K, and the locking portion 9 of the movable piece 2 comes into contact with the stopper 13 of the fixed piece 3. If it will be in such a state, since the movement of the movable piece 2 will be restrained with the stopper 13, it will be in the stable state.

  To lower the shelf in a horizontal state after using the shelf, lift the center of the shelf from below as shown in FIG. Since the locking of the movable piece locking portion and the fixed piece stopper is released simply by tilting, the shelf board can be easily lowered. This is the reverse of the work of raising the shelf, that is, the work in FIG. 4 may be performed in the order of (C), (B), (A).

  Next, a second embodiment will be described. The second embodiment is a folding bracket suitable for attaching a shelf board to a stepped portion of a cupboard having a stepped portion formed in the middle as shown in FIG. Behind the stepped portion of the cupboard is a storage unit that can store tableware and cooking utensils. The folding bracket requires a lower mounting surface in which the fixed piece is mounted on the lower surface of the stepped portion and a vertical mounting surface that is mounted on the mounting portion in the vertical direction below the storage portion. A second embodiment will be described with reference to FIGS. FIG. 6 is a perspective view of the folding metal fitting of the second embodiment as viewed obliquely from below, FIG. 7 is a plan view thereof, FIG. 8 is a side view thereof, and FIGS. It is explanatory drawing until it lifts a shelf board sequentially and it is in a horizontal state.

  6-9 of 2nd Example, the same code | symbol as 1st Example is attached | subjected to the part same as 1st Example, and the description is abbreviate | omitted.

  The folding metal fitting 1 of the second embodiment is composed of a movable piece 2 attached to the shelf board T and a fixed piece 3 attached to the furniture K. The movable piece 2 forms two surfaces bent at right angles, one surface being a plate attachment surface 4 attached to the lower surface of the shelf T, and the other surface being a connection surface 5 connected to the fixed piece 2.

  In the second embodiment, the locking portion 9 formed below the protruding portion 7 has a concave shape that is recessed inward. The concave locking portion 7 makes the locking to the plate-like stopper 13 protruding laterally of the fixed piece even better.

  The folding bracket attached to the step of the cupboard has a plate-like lower surface, so that the attachment surface attached to the lower surface is the lower attachment surface, and there is a vertical attachment point below the step. Therefore, the attachment surface attached to the vertical attachment portion is a vertical attachment surface. Therefore, in the second embodiment, the longitudinal mounting surface 10 bent at right angles to the shaft support surface 11 and the lower mounting surface bent upward with respect to the shaft support surface, that is, the upper portion of the shaft support surface 11 is extended. The lower mounting surface 16 is formed by bending the extension portion inward at a right angle. The lower mounting surface 16 is formed at a position so as to be flush with the plate mounting surface 4 of the movable piece when the movable piece 2 is lifted as shown in FIG. The lower mounting surface 16 has a plurality of screw insertion holes 17.

  The shaft support surface 11 is formed with a stopper 13 that can be locked with the locking portion 9 of the movable piece 2 when the shelf board is in a horizontal state as shown in FIG. The stopper is a horizontal plate in which a U-shaped cut is vertically formed in the shaft support surface 11 and the cut is bent at a right angle inward. Therefore, when the plate-like stopper 13 and the concave locking portion 9 are locked, the locking is further ensured and the shelf board can be stabilized.

    Next, attachment of the folding metal fitting of the second embodiment having the above-described configuration and its operating state will be described.

  First, the folding bracket 1 is attached with the vertical mounting surface 10 of the fixed piece 3 placed at a vertical mounting position of the cupboard with the plate mounting surface 4 of the movable piece 2 and the vertical mounting surface 10 of the fixed piece 3 at right angles. In this state, the shelf board T is placed on the board mounting surface 4 so that the side face of the shelf board T and the side face of the step part D of the cupboard are brought into contact with each other, and the upper surface of the shelf board T and the upper face of the step part D To be on the same plane. In this state, a wood screw is screwed through the screw insertion hole 12 of the vertical mounting surface 10 of the fixed piece 3 to fix the folding bracket 1 to the vertical mounting portion of the cupboard step, and the screw of the lower mounting surface 16 A wood screw is screwed into the insertion hole 17 and fixed to the step portion D. One folding bracket is attached near each end of the shelf. Thereafter, a wood screw is screwed into the screw insertion hole 6 of the plate mounting surface 4 of the movable piece 2 to fix the movable piece 2 to the shelf plate T.

  If the fixed piece 3 is fixed at a predetermined position on the furniture, the movable piece 2 is lifted as shown in FIG. 9D, that is, the plate mounting surface 4 of the movable piece 2 is horizontal and long. After the connecting pin 14 is positioned at the top of the hole 8, the shelf plate T is placed on the plate mounting surface 4 of the movable piece 2 so that the end surface of the shelf plate T is almost in contact with the stepped portion D. A wood screw is screwed into the screw insertion hole 6 of 4 and the movable piece and the shelf board T are fixed.

  The raising and lowering of the shelf board T in the second embodiment will be described.

FIG. 9A: A state in which the shelf board T is lowered, that is, a state before the shelf board T is used. At this time, the connecting pin 14 is located at the lowermost part of the elongated hole 8 (the upper part in FIG. 9A).
FIG. 9B: In order to take out the item stored in the cupboard and place it on the shelf board T, the object is lifted upward while holding the end of the shelf board T.
FIG. 9C: When the shelf board T is further lifted, the shelf board T becomes horizontal. At this time, the connecting pin 14 is still located at the lowermost part of the long hole 8.
FIG. 9D: When the shelf board T is in a horizontal state, the shelf board T is lowered downward with its own weight due to the weight of the shelf board. At this time, since the bottom of the long hole 8 is inclined toward the stepped portion, the long hole 8 slides on the connecting pin 14 so that the movable piece 2 approaches the vertical mounting surface 10 of the fixed piece 3. When the connecting pin 14 reaches the uppermost portion of the long hole 8, the shelf plate T also approaches the step portion D, and the locking portion 9 of the movable piece 2 comes into contact with the stopper 13 of the fixed piece 3. In such a state, since the movable piece 2 is restrained from moving by the stopper 13, the movable piece 2 is in a stable state. Absent.

  To lower the shelf in a horizontal state after using the shelf, simply lift the center of the shelf from below and tilt the tip of the shelf, that is, the anti-furniture side downward. Since the locking portion is released from the stopper of the fixed piece, the shelf board can be easily lowered. This is the reverse of the work of raising the shelf, that is, the work in FIG. 9 may be performed in the order of (c), (b), (a).

  Next, a third embodiment will be described. The third embodiment is a folding bracket suitable for adding the auxiliary top plate H to the table of the narrow top plate M as shown in FIG. A third embodiment will be described with reference to FIGS. FIG. 11 is a perspective view of the folding metal fitting of the third embodiment as seen obliquely from below, FIG. 12 is a plan view thereof, FIG. 13 is a side view thereof, and FIGS. It is explanatory drawing until it lifts and raises an auxiliary top plate to a horizontal state sequentially. (X) in FIG. 15 is a table in a non-use state with the auxiliary top plate lowered, and (Y) is a table in a use state with the auxiliary top plate raised.

  In FIGS. 11 to 14 of the third embodiment, the same parts as those of the first embodiment are denoted by the same reference numerals as those of the first embodiment, and the description thereof is omitted.

  The folding metal fitting 1 of the third embodiment includes a movable piece 2 attached to the auxiliary top plate H and a fixed piece 3 attached to the top plate M.

  The movable piece 2 forms two surfaces that are bent at right angles. One surface is a lower mounting surface 4 that is attached to the lower surface of the auxiliary top plate H, and the other surface is a connection surface 5 that is connected to the fixed piece 2.

  The fixed piece 3 of the folding metal fitting of the third embodiment also forms two surfaces bent at right angles, one surface is connected to the lower mounting surface 16 attached to the top plate M, and the other surface is connected to the connecting surface 5 of the movable piece 2. It becomes the shaft support surface 11 to do. That is, the mounting surface of the third embodiment is a lower mounting surface bent upward with respect to the shaft support surface. The lower mounting surface 16 has a plurality of screw insertion holes 17.

  In the third embodiment, the locking portion 9 formed below the connecting surface 5 is a recess recessed inward as in the second embodiment. The reason why the locking portion is a recess is that the stopper 13 of the fixed piece 3 is in the shape of a plate protruding laterally, and the locking with the stopper is good.

  The shaft support surface 11 is formed with a stopper 13 that can be locked with the locking portion 9 of the movable piece 2 when the auxiliary top plate is in a horizontal state as shown in FIG. The stopper is obtained by extending the lower portion of the shaft support surface 11 and bending the extension portion inward at a right angle. Accordingly, when the plate-like stopper 13 and the concave locking portion 9 are locked, the locking is ensured and the auxiliary top plate can be stabilized.

    Next, attachment of the folding fitting of the third embodiment having the above-described configuration and its operating state will be described.

  The folding bracket is attached near both ends of the top plate and the auxiliary top plate. Therefore, in attaching the folding bracket in the third embodiment, first, the side surface of the top plate M and the side surface of the auxiliary top plate H are brought into contact as shown in FIG. Further, as shown in FIG. 14D, the mounting bracket 1 is in a state where the upper mounting surface 16 of the fixed piece 11 and the planing surface 4 of the movable piece 2 are the same surface. Then, the fixing piece 3 and the top plate M are fixed by screwing wood screws from the screw insertion holes 17 of the lower mounting surface 16 so that the center of the mounting bracket 1 coincides with the contact portion of the top plate M and the auxiliary top plate H. And a wood screw is screwed through the screw insertion hole 6 of the plate mounting surface 4 of the movable piece 2 to fix the movable piece 2 and the auxiliary top plate H.

  The raising and lowering of the auxiliary top plate in the third embodiment will be described.

FIG. 14 (a): A state in which the auxiliary top plate H is lowered, that is, a state before the auxiliary top plate is used. At this time, the connecting pin 14 is positioned at the lowermost part of the elongated hole 8 (the upper part in FIG. 14A).
FIG. 14 (b): Hold the end of the auxiliary top plate H and lift it upward to widen the table.
FIG. 14C: When the auxiliary top plate H is further lifted, the auxiliary top plate becomes horizontal. At this time, the connecting pin 14 is still located at the lowermost portion of the long hole 8.
FIG. 14 (d): When the auxiliary top plate H is in a horizontal state, the auxiliary top plate H is lowered downward with its own weight due to its own weight. At this time, since the lower portion of the long hole 8 is inclined toward the fixed piece side, the long hole 8 slides on the connecting pin 14 so that the movable piece 2 approaches the fixed piece 3. When the connecting pin 14 reaches the uppermost portion of the long hole 8, the side surface of the auxiliary top plate H approaches the side surface of the top plate M of the table, and the engaging portion 9 of the movable piece 2 contacts the stopper 13 of the fixed piece 3. Touch. In such a state, since the movable piece 2 is restrained from moving by the stopper 13, the movable piece 2 becomes stable, and the auxiliary top plate is inclined even if a heavy object is placed on the auxiliary top plate or a person touches it. There is nothing to do.

  To lower the shelf that is in a horizontal state after using the auxiliary top, simply lift the center of the auxiliary top from below and lower the tip of the auxiliary top, that is, move the auxiliary top to the side opposite to the top Since the locking of the movable piece locking portion and the fixed piece stopper is released simply by inclining, the auxiliary top plate can be easily lowered. This is the reverse of the work of raising the auxiliary top, that is, the work in FIG. 14 may be performed in the order of (c), (b), and (b).
