Description

  The present invention relates to a folding table that can be folded and stored. In particular, the table includes a tall type table with a high top plate, and a face-to-face table that is used facing both front and rear.

  2. Description of the Related Art Conventionally, there is a foldable table having three panel members fixed to a top plate so as to have a U-shape in plan view (see, for example, Patent Document 1). Of the three panels in such a folding table, the curtain panel (front panel) is fixed to both side panels (two side panels) and the legs on its sides, thereby increasing the rigidity of the entire table. Can do. In particular, in a folding table, it is possible to suppress a decrease in rigidity during assembly by the folding mechanism.

  Here, in a tall type facing table (for example, a counter table or a half-seat facing table used in combination with a half-seat chair) with a relatively long leg and a high top plate, It is desirable in terms of appearance that the curtain is a relatively long stringer covering from the bottom of the top plate to the vicinity of the floor. Especially in face-to-face tables, the appearance with curtains is important.

In other words, the curtain plate (front panel) provided along the horizontal width direction of the table covers the table top and below to adjust the appearance and protect the privacy of the table user. In particular, in the face-to-face table, it is necessary to cover the space from the top plate to the vicinity of the lower end of the table, having a sufficient height as the leg portion, from the viewpoint of appearance and partitioning the space of the facing user.
Registered Utility Model No. 3084742

  However, when the tall type is adopted in the above conventional folding table, when the curtain is a relatively long stringer covering from the bottom of the top to the vicinity of the floor, the folding of the curtain is folded on the top. In the state, the curtain will protrude greatly from the top board.

  For this reason, it is bulky when stored and transported in a folded state, and it is not easy to carry and handle when folded. In addition, the curtain that protrudes in a folded state may be easily damaged during storage and transportation, and the appearance of the curtain may not be maintained due to handling during folding.

  Therefore, the present invention has been made to solve such a problem, and employs the following means (1) to (3).

  (1) That is, the folding table of the present invention includes a top plate 1, leg portions fixed to the upper end of the top plate 1 so as to be able to fall from the left and right side portions (hanging positions thereof) in the center direction. A folding table comprising a curtain plate 3 fixed at the upper end so as to be able to fall in the depth 1d direction (front-rear direction) of the ceiling plate 1 between the legs on the back side of the ceiling plate 1, The stringer 3l is longer than the depth 1d of the top plate 1, and the curtain plate 3 is provided with a folding structure that can be folded upward at at least one folding side 3s and folded by the curtain plate 3 itself. Features.

  If it is such, the curtain board 3 can be folded up by a bending structure, and the stringer 3l of the curtain board 3 can be made into the short folded state. Therefore, the folded state can be formed by tilting the curtain plate 3 to the top plate 1 in the folded state, and the folded state formed thereby does not cause the collapsed curtain plate 3 to largely protrude from the top plate 1. It becomes a compact form.

  Further, by folding the curtain plate 3 by the folding structure, the decorative surface of the curtain plate 3 can be protected by itself in the folded state.

  Further, when the table is assembled and used in a compact folded state, it is possible to form a table with a good appearance in which the curtain 3 covers the lower part of the top plate 1 to the vicinity of the lower end. That is, since the vertical girder 3l in the assembled state of the curtain plate 3, that is, the height of the curtain plate 3 extends from the top plate 1 to the vicinity of the lower end of the leg portion, the curtain plate 3 having excellent shielding properties and partition display properties is obtained. It will look good in the time of use. In particular, a table having the curtain 3 extending to the vicinity of the lower end is suitable for a counter table or a face-to-face table.

  (2) Further, as the folding table, the leg portion has a pair of side plates 2 fixed along the left and right depths 1 d of the top plate 1, and the upper ends thereof are along the back surface of the top plate 1. It is good also as what can be folded up and can cover the curtain board 3 (above) folded and folded down from both sides.

  If it is such, the overlapping part which overlaps with the top plate 1 of the curtain 3 tilted to the back surface of the top plate 1 in the folded state can be protected. That is, by tilting the curtain plate 3, the side plate 2 can cover and protect the surface of the curtain plate facing in the same direction as the back surface of the top plate 1.

  In particular, if the decorative surface is formed on one of the front and back surfaces of the curtain plate 3 and this decorative surface is folded so as to face the opposite direction when folded, all the decorative surfaces of the curtain plate 3 in the folded state. Can be protected.

  In other words, in the folded structure, the decorative surface of the curtain plate 3 in the folded state is “the decorative surface under the curtain plate” facing the rear surface of the top plate 1 and the “curtain” facing the same direction as the rear surface of the top plate 1. The former “upper face of the curtain” is protected by the contact surface of the top plate 1 and the latter “upper face of the curtain” is protected by the side plate 2. It will be protected by covering. Further, the decorative surfaces of the curtain plate 3 do not touch each other and are not damaged. As a result, all the decorative surfaces of the curtain 3 are protected.

  (3) Further, as one of the folding tables, the curtain plate 3 may be hung at a hung position near the center in the depth 1d direction of the top plate 1.

  If it is such, it will become suitable for the facing type folding table which can be used facing from the front and back both sides of the top plate 1. That is, when facing each other, each person's feet facing each other can be stored in the lower part of the top board 1.

  When the leg portion is a pair of side plates 2, the top plate 1 is composed of three plates (total of two side plates and one curtain plate) combined in a substantially H shape in plan view. It has a structure that supports the structure and has excellent rigidity and durability during assembly. That is, for example, it is not necessary to employ a slide structure in which the upper end of the curtain plate 3 is slid to one of the front and rear ends of the top plate 1 and then overlapped with the top plate 1. Compared with a folding table that employs such a slide structure, the hanging mechanism of the curtain plate 3 is simple and rich in rigidity and durability.

  In addition, the hanging position near the center in the depth 1d direction in the present invention refers to a position excluding the front and rear ends in the depth direction 1d. This position is a position that should be determined to be substantially H-shaped in a plan view when the leg portion is the pair of side plates 2 at and near the center in the depth 1d direction of the top plate 1, and is a face-to-face table. It means the position of the range that can be used without any problem.

  The present invention has the following effects by adopting the above structure. That is, the curtain plate does not protrude greatly from the top plate, and a compact folded state is obtained. For this reason, it does not become bulky during storage and transportation in a folded state, and is easy to carry.

  Further, since the decorative surface of the curtain plate can be protected by itself in the folded state, it is not easily damaged even when stored and transported in the folded state, and the curtain plate is excellent in appearance.

  Hereinafter, the configuration of the present invention will be described in detail based on the drawings shown as examples. FIG. 1 is a perspective view of the folding table according to the first embodiment of the present invention, and FIGS. 2 to 6 are perspective views illustrating steps of folding the folding table according to the first embodiment. FIGS. 7 and 8 are front view and plan view partial explanations showing the structure of the lower left portion of the front plate of the side plate 2 and the curtain plate lower plate 32 in the assembled state where the folding table of Example 1 is assembled, that is, in the use state of the table. FIG. FIG. 9 is a perspective view showing an assembled state in which the shelf board 6 is attached to the folding table of the first embodiment. FIG. 10 is a perspective view showing the folding table of Example 2 with the lower casters 7 attached.

  The folding table according to the present invention is a tall type in which the leg length (the vertical girder 21 of the side plate 2 in this embodiment) is relatively long and the height of the top plate 1 is high, and the legs are inserted from both the front and back of the top plate 1. A plurality of face-to-face tables with a structure that has a horizontally long top plate 1 having a width 1w greater than a depth (depth girder) 1d and left and right sides of the back side of the top plate 1 (which can be tilted in the center direction). And a curtain plate 3 which is fixed at the upper end along the horizontal width 1w direction on the back side of the top plate 1 between the (a pair of) side legs.

  Hereinafter, each part will be described in detail. The top plate 1 has a horizontally long shape having a width 1w larger than the depth 1d (FIG. 1). Thereby, even if it is a tall type table with a long leg part, the leg part which fell on the back surface of the top plate 1 does not protrude from the top plate 1, and a compact folding state can be formed.

  Further, the rod-shaped cushioning material 1c is bonded and fixed to one side in the depth 1d direction from the suspended position of the curtain plate 3 on the back surface of the top plate 1. The bar-shaped cushioning material 1c is made of a porous elastic body having a bar-like cushioning property, and cushions the contact surface between the curtain plate 3 and the top plate 1 that are folded in a folded state. It is preferable in terms of appearance that the rod-shaped cushioning material 1c is fixed to the position on the non-decorative surface side of the curtain plate 3 (front (front side in FIG. 1)) along the width 1w direction of the top plate 1. This is because if the side on which the rod-shaped cushioning material 1c is fixed (the non-decorative surface side of the curtain plate 3) is positioned in front, that is, in front, it is not visually recognized by the person facing the user when assembled and used ( (See FIG. 1).

  The plurality of legs are fixed at the upper ends near the left and right ends on the back side of the top plate 1. Each has a collapsible structure at the upper end fixing portion or near the upper end. As a specific embodiment, the legs are preferably a pair of side plates 2 fixed along the depth 1d direction of the left and right sides of the top plate 1 as shown in FIGS. In addition, a plurality of (for example, four) pedestals fixed to the periphery (for example, four corners) of the top plate 1 may be used (not shown).

  The left and right legs can be tilted from the left and right in the center direction at a fixed location near the upper end. In other words, the left leg is tilted along the right direction 1w of the top plate 1 and the right leg is tilted along the left direction 1w of the top plate 1 (FIGS. 5 and 6). By this tilting, the folding table of the present invention forms a folded state.

  The retractable structure of the leg part is a structure that bends inward in the vicinity of the upper end of the leg part and falls down to a state along the top board 1. Moreover, it is the structure which covers the upper direction (the back side direction of the top plate 1) of the curtain plate 3 in a fallen state by the fall of the side plate 2 which is a leg part (refer FIG. 6). As a result, the decorative surface of the upper part of the curtain plate 3 exposed in the direction of the back side of the top board 1 can be protected when the curtain plate 3 is in a tiltable state.

  The length of the leg portion (in this embodiment, the vertical beam 2l of the side plate 2) is determined arbitrarily depending on the use / specifications of the folding table, but is preferably shorter than the lateral width 1w of the top plate 1. As a result, the left and right leg portions do not protrude from the top plate width 1w direction in the state in which the leg portions are retractable, and a compact folded state can be formed.

  In this embodiment, the length of the leg means the vertical beam 21 of the side plate 2. More preferably, the vertical girder 21 of the side plate 2 that is the leg length is shorter than the half of the horizontal width 1w of the top plate. If it is such, it will be in the state which left | separated the lower end of the side plates 2 of both sides, without overlapping, or in the state which a lower end partly contacts in a fallable state. These states are as shown in FIG. 6 in which the left and right legs do not overlap with each other, so that a compact folded state is formed in the thickness direction.

  Further, it is preferable that the left and right leg length adjusters 21 projecting from the lower end are fitted to each other and the fitting structure (not shown) can be locked in the fallable state in the fallable state of the side plate 2 as the leg portion.

  As an example of the fitting structure, for example, when the left and right leg length adjusters 21 projecting from the lower end are made of decorative bolts (FIG. 2) having a square-shaped makeup head screwed to the lower end of the side plate 2, Is mentioned.

  That is, there is a fitting structure (not shown) in which the leg length adjuster 21 is fixed at a position shifted by a radial difference between the disk portion and the screw portion on each of the left and right sides of the side plate 2. In this structure, in the state in which the side plate 2 that is the leg portion is tiltable, the disc portions are fitted to each other by providing a difference in length between the screwed positions of the left and right leg length adjusters 21.

  In addition, it is also possible to adopt a structure in which fitting members that simultaneously fix the left and right leg length adjusters 21 are attached. The fitting member is a member that is formed with a concave shape that covers the protruding portion (screw portion and decorative head) of the leg length adjuster 21 at both ends, and the distance between the lower ends of the left and right side plates 2 in the fallen state is the total length. (Not shown). Another example of the fitting member is a belt that is wound along the width 1w direction.

  The fitting structure (not shown) prevents the folding state from being accidentally released when the folding table in the folded state is transported or moved.

  The curtain plate 3 has at least one of the front and back as a decorative surface, and the upper edge 3u extends along the horizontal width 1w direction on the back side of the top board 1 so that both ends (front and rear ends) of the top board 1 in the depth 1d direction. The upper end is fixed toward the center from either of these. Further, the curtain plate 3 itself has a folding structure at the upper end fixing portion or near the upper end, and also has a bent structure at portions excluding the vicinity of the upper end (near the center in the height direction and the lower end).

  The curtain 3 is a vertical girder 31 that reaches the vicinity of the floor below the top board 1 in the assembled state, and does not protrude from the top board 1 in the folded state, which is desirable in any state.

  The suspension position of the curtain plate 3 on the top plate 1 is closer to the center in the depth 1d direction, excluding the vicinity of both ends (front end and rear end) in the depth 1d direction of the top plate 1, that is, more central than the both ends in the front-rear direction of the top plate 1 Is a position. In the embodiment, when the decorative surface side of the curtain plate 3 is set to the back side or the rear side in the depth 1d direction, it is fixed to the back (back side) from the center in the depth 1d direction (FIG. 1).

  Since the curtain 3 is positioned closer to the center excluding the vicinity of both ends, the front and back facing persons can use it without getting in the way of the curtain 3. Therefore, it is preferable as a facing table (see FIG. 1). Contrary to the hanging position of the present invention, if the curtain plate 3 is located at the end of the top plate 1 in the depth 1d direction, the lower body of the facing person does not enter and it is not suitable for the use of the facing table.

  The retractable structure of the curtain plate 3 is hung so that it can be folded down to the state along the top board 1 by bending in the depth 1d direction (front side or back side) near the upper end of the curtain plate 3. It is a suspended structure.

  Thus, the folding structure is a structure in which the curtain plate 3 itself can be folded by folding upward at at least one folding side 3 s extending in the width 1 w direction of the curtain plate 3. .

  In particular, in the folded state, if the curtain plate 3 tilted to the top plate 1 does not protrude from the front end (or the rear end) of the top plate 1 at all, an extremely compact planar form is obtained.

  Specifically, in a toll type folding table whose legs are longer than the depth 1d of the top board 1, the folding edge 3s from the upper end side 3u of the curtain plate 3 (the uppermost position in the case of a plurality of folding sides 3s). The vertical distance to the bent side 3s) is shorter than the distance from the hanging position of the curtain plate 3 to the front end (or rear end) of the top plate 1 in the tiltable direction.

  If it is such, the curtain plate 3 along the top plate 1 will not protrude from the front end (or rear end) of the top plate 1 at all (see FIG. 4). That is, by providing such a length relationship and a folding structure, a very compact folding table in a folded state can be obtained.

  Further, the bent side 3s is preferably provided at a position obtained by equally dividing the vertical beam 3l of the curtain plate 3 along the horizontal width 1w direction of the curtain plate 3. As a result, it is possible to effectively secure the vertical beam 3l of the curtain plate 3 during assembly. The curtain plate 3 itself can be folded in plural. The folding structure of the embodiment is a two-fold structure with one folding side 3s, parallel to the horizontal width 1w direction of the curtain plate 3, and the vertical beam of the curtain plate 3 so as to divide the vertical beam 3l into two equal parts. It is provided at a position 3l ′ which is half of 3l (FIG. 3).

  In addition, as an embodiment different from the present embodiment, a multi-folded bent structure having a plurality of parallel bent sides 3s may be used. If it has a plurality of bent sides 3s, the stringer 3l of the curtain plate 3 can be made extremely short by bending. For this reason, a table of a tall type whose legs are longer than the depth 1d of the top plate 1 or the curtain plate 3 is fixed to the center of the top plate 1 (that is, it is possible from the suspended position of the curtain plate 3). Even in a face-to-face table in which the distance to the end of the top plate 1 (front or rear) in the tilted direction is shorter than the top plate depth 1d, the collapsed curtain plate 3 does not protrude from the top plate 1 The folding table can be in a folded state.

  Specifically, the curtain plate 3 is formed by joining a curtain plate upper plate 31 and a curtain plate lower plate 32 with a pair of left and right hinges so that the decorative surface can be folded outward in one direction.

  The curtain plate upper plate 31 is supported and fixed to the top plate 1 by a curtain plate suspension structure 41 provided in the vicinity of the upper end on the upper left and right sides. Specifically, the curtain plate suspension structure 41 is a structure in which projecting bars 41a projecting left and right along the curtain plate upper end side 3u are fitted into the left and right curtain plate support holes 41b on the back side of the top plate 1. By being supported by the projecting bar 41a, the curtain plate can be tilted without shifting the suspended position of the upper end side 3u on the back surface of the top plate 1, and the top plate is reliably supported by the upper surface of the upper end side 3u.

  The lower side of the curtain plate upper plate 31 is adjacent along the upper side of the curtain plate lower plate 32 described below by a pair of left and right hinge structures near both ends. The lower side of the curtain plate upper plate 31 and the upper side of the curtain plate lower plate 32 constitute a folded side 3s of the folded structure.

  On both side portions of the curtain plate lower plate 32, curtain plate side portion fixing structures 42 for fixing the form and angle of the curtain plate 3 are fixed in the vicinity of the upper and lower ends of the side edges (FIG. 1). That is, four curtain plate side fixing structures 42 are provided at substantially diagonally extended positions of the curtain plate lower plate 32, thereby ensuring that the curtain plate 3 is opened in a flat plate shape and the top plate 1 of the curtain plate 3. Fix the hanging angle with respect to. Each curtain plate side portion fixing structure 42 is a saddle structure including a rod 42 a that can be accommodated in the plane of the curtain plate lower plate 32, and a hole 43 b provided in the side plate 2.

  One end of the short bar is fixed to the inner side of the curtain plate lower plate 32 so as to be substantially L-shaped in plan view (FIGS. 7 and 8). The short bar at the end is an operation lever for the bar 42a as well as preventing the bar 42a from coming out of the curtain plate lower plate 32 to the outside. In addition, a spherical crown-like protrusion is fixed to the center of the side portion of the club 42a by a transverse through rod (FIGS. 7 and 8). The protrusions on the side portions are positioning members for fixing the collar position, and are also used to prevent the collar rod 42a from coming inward from the curtain plate lower plate 32.

Further, in both side portions of the curtain plate lower plate 32, in the vicinity of the upper portion of the lower curtain plate side portion fixing structure 42, a spherical crown cushioning material 3c that cushions the contact with the side plate 2 is provided.
Further, of the both sides of the curtain plate lower plate 32, the side plate 2, the curtain plate 3, and the upper portion of the spherical crown cushioning material 3 c (and in the vicinity of the upper portion of the lower curtain plate side portion fixing structure 42) A side plate fixing structure 5 that fixes the position of the side plate 2 is provided. The side plate fixing structure 5 has a vertically long hole 5b provided in a vertically long plate provided perpendicular to the side plate 2 along the inside of the side plate 2, and a curtain plate lower plate 32 so that the tip can be fitted into the vertically long hole 5b. And a substantially U-shaped curved plate 5a.

  The curtain plate side portion fixing structure 42 and the side plate fixing structure 5 can hold and fix the assembled state in which the folding table is assembled, and can ensure safe use. Also, the folding work can be done quickly and safely.

  The folding table of this invention comprised as mentioned above forms a folding state by folding as follows.

  First, as shown in FIG. 2, after the top plate 1 is turned upside down so that the top plate 1 is downward, the fixing of the curtain plate side portion fixing structures 42 on both sides of the curtain plate lower plate 32 is released and continued. Then, the fixing of the side plate fixing structure 5 is released. Then, as shown in FIG. 3, the curtain plate lower plate 32 positioned above by overturning is folded along the curtain plate upper plate 31 from the folding side 3 s and folded into two to fold the curtain plate 3. Is folded. At this time, since the side plate fixing structure 5 is positioned immediately below the curtain plate side portion fixing structure 42 in the inverted state, the work can be continuously performed.

  Next, the curtain plate 3 in a state in which the curtain plate 3 is folded in half is tilted so that the curtain plate lower plate 32 is in contact with the top plate 1, and the curtain plate 3 is brought into a folding state as shown in FIG. . By tilting the curtain plate lower plate 32 in the direction in which the curtain plate lower plate 32 comes into contact with the top plate 1, the decorative surface of the curtain plate upper plate 31 that is easily noticeable during assembly can be protected. At this time, the folded curtain plate 3 comes into contact with the bar-shaped cushioning material 1c fixed to the back surface of the top plate 1, and therefore does not contact the back surface of the top plate 1.

  Next, as shown in FIG. 5, the side plate 2 is tilted in the left-right order along the back surface of the top plate 1 to cover the folded curtain plate 3 from both sides. Accordingly, the folded state is as shown in FIG.

  At the time of assembly, this series of folding work steps is retroactively performed in reverse.

  In the present invention, for example, as shown in FIG. 9, the shelf board 6 may be attached by a slide structure in an assembled state, and as shown in FIG. It may be included. In addition, the present invention is not limited to the above-described embodiments including the specific configuration of each part, and various modifications and combinations are possible without departing from the spirit of the present invention.
