Description

  The present invention relates to a table suitably used in an office or the like.

  Conventionally, there are various types of tables that are preferably used in offices, etc., which have been changed easily for the purpose of frequently changing the office layout, or sometimes using the office space widely and effectively. It has been proposed (see, for example, Patent Document 1).

  The device described in Patent Document 1 not only allows the legs to be easily removed from the top board, but also extends over other top boards of the same or different sizes by changing the arrangement of the legs with respect to the top board. By attaching the legs and connecting the top plates together, the space on the top plate can be used widely and effectively.

  As described above, in order to widely use the office space itself, it may be considered to make the table itself compact and withdraw. In view of performing such a table removal operation quickly and easily, it is desirable that the table can be quickly attached to the top plate.

  Here, not only the top plate but also a structure that can easily connect and release the members is generally a structure used for a tripod for a camera (see, for example, Patent Document 2).

  The one described in Patent Document 2 has an attachment / detachment portion having a predetermined shape attached in advance to a camera, that is, a supported body, and an operation portion for pressing and fixing the tripod body, that is, the support body, to the attachment / detachment portion. The supported body can be easily attached and detached by only a simple operation on the operation portion.

  However, in such a structure, the support strength of the support body such as a camera directly depends not only on the strength of the operation portion itself pressing the detachable portion but also on the assembly strength. That is, when trying to apply the structure as described in Patent Document 2 to the table, the operating portion must be assembled to increase the strength until it can withstand the load and external force applied to the top plate. Inevitable. As a result, if such a structure is applied, the table cannot be configured compactly.

And have.

  Thus, in this embodiment, as shown in FIGS. 8 to 12, the tension member 130 is rotated by the sliding operation surface 12d, which is the other inner surface 12b for tightening, and the other outer surface for tightening. A pushing operation is performed between the pressed surface 22d and the side surface 22b. The tension member 130 can operate so as to be rotatable between the locked state (P) and the unlocked state (Q). In this embodiment, the tension member 130 is in a state in which the protrusion 22 is inserted into the recess 12 by always contacting the sliding contact surface 12d from the locked state (P) to the unlocked state (Q). In the state where it is rotated even a little from the unlocked state (Q), it always comes in contact with the sliding contact surface 12d, and when it can contact the pressed surface 22d of the protrusion 22, it always touches the sliding contact surface 12d. ing. Specifically, the tension member 130 includes a sliding contact surface 130a that is always in contact with the sliding contact surface 12d, a retracting surface 130b that retracts from the contacted surface 12c in the unlocked state (Q), and the locked state. In (P), a pressing surface 130d that presses the pressed surface 22d, a transition surface 130c interposed between the retreating surface 130b and the pressing surface 130d, and an operation that protrudes outward at the outermost edge of the tension member 130 itself. An operating lever 130e having an end 130g and a positioning projection 130f that determines the operating range of the tension member 130 itself by projecting outward in the vicinity of the operating lever 130e. The sliding contact surface 130 a and the contact surface 22 c are formed in a partial arc shape having the same diameter from the rotation center of the tension member 130. The retracting surface 130b has a shape in which the outer edge of the tension member 130 is cut out linearly, and is formed so as to be opposed to the pressed surface 22d of the protrusion 22 in the unlocked state (Q). The transition surface 130c is curved while having a shape cut away from the pressing surface 130d so as to have a smaller diameter, and has a shape that is continuous with the retraction surface 130b. Accordingly, the transition surface 130c gradually approaches the pressed surface 22d, that is, one side in the operation from the unlocked state (Q) to the locked state (P).

  Hereinafter, with respect to the mode until the leg 2 is attached to the top plate 1 with the tension member 130 in the unlocked state (Q) by the fixing mechanism 13 and the leg 2 is firmly fixed in the locked state (P), FIG. 6 and FIG. 9 to FIG.

  First, as shown in FIGS. 4 and 9, the tension member 130 is first placed in the unlocked state (Q) in which the operation lever 130 e is positioned so that the operation end 130 g is farthest from the leg 2. At this time, the positioning protrusion 130 f of the tension member 130 is in contact with a release-side protrusion 122 c that is projected from the mechanism mounting portion 122. From this state, as shown in FIG. 10, the protrusion 22 attached to the upper end of the leg 2 is inserted toward the protrusion accommodating portion 121 in the recess 12. In the state shown in the figure, the slidable contact surface 130a of the tension member 130 is in contact with the slidable contact surface 12d, but the contact surface 22c of the protrusion 22 is in contact with or in close proximity to the contacted surface 12c. The pressed surface 22d of the protrusion 22 is opposed to the retracting surface 130b of the tension member 130 and is in a separated state. When the operation lever 130e is rotated by, for example, picking the operation end 130g from the state shown in the figure, the transition surface 130c faces the pressed surface 22d and gradually approaches the pressed surface 22d, or the recessed portion 12 is covered. When the contact surface 12c is separated from the contact surface 22c, the pressed surface 22d is gradually pressed. In the locked state (P) shown in FIG. 11, the positioning protrusion 130f abuts on the lock-side protrusion 122b, the pressing member 130 abuts the pressing surface 130d against the pressed surface 22d, and the sliding contact surface 130a contacts the sliding contact surface 12d. It is in contact. At this time, the contact surface 22c of the protrusion 22 is in contact with the contacted surface 12c of the recess 12 without a gap. Since the abutted surface 12c is inclined upward, an upward force is applied to the protrusion 22 by the pressure from the tension member 130. As a result, as shown in FIG. 12, the protrusion 22 is strongly pressed by the pressing inner member 12 a located on the upper side of the fitting outer surface 22 a by the pressing from the tension member 130, and the protrusion 22 is strong. Is positioned. In other words, the tension member 130 is firmly stretched between the recess 12 and the protrusion 22. In this locked state (P), the operation lever 130e is positioned toward the inside of the top plate 1 at a position close to the leg 2, so that the operation end 130g is hardly interfered from the outside.

  Further, in the locked state (P) shown in FIGS. 11 and 12, the load receiving surface of the top plate support member 23 receives the loads from the recess 12 and the core material 11, respectively. It is also effectively avoided that an excessive load is applied to the recess mounting portion 11b.

  By adopting the configuration as described above, the table according to the present embodiment is required to unnecessarily strengthen the mounting strength and assembly strength of the component that fixes the protrusion 22 to the recess 12 when in the locked state (P). Even if the tension member 130 itself has strength, a firm engagement in the locked state (P) is realized by the tension. As a result, a table has been realized in which the legs 2 are firmly attached even with a simple structure.

  In this embodiment, in order to adopt a configuration in which the attachment location of the tension member 130 is always strong against an external force and a load at the time of operation between the locked state (P) and the unlocked state (Q), Specifically, the tension member 130 is in contact with the other fastening inner side surface 12b whenever the sliding contact surface 130a can contact the other fitting outer side surface 22a.

  In this embodiment, in order to configure the tension member 130 having a high strength against an external force or a load applied during operation, the tension member 130 is always in the state from the locked state (P) to the unlocked state (Q). From the sliding contact surface 130a that operates while contacting the sliding contact surface 12d that is the other fastening inner surface 12b, and the pressed surface 22d that is the other fastening outer surface 22b in the unlocked state (Q). A configuration having a retracting surface 130b that retracts and a pressing surface 130d that presses the pressed surface 22d that is the other tightening outer surface 22b in the locked state (P) is applied.

  In this embodiment, in order to avoid a sudden load during the operation between the locked state (P) and the unlocked state (Q), in the present embodiment, the lock surface 130b and the pressing surface 130d are connected with the lock. A transition surface 130c is provided that gradually presses or gradually approaches the pressed surface 22d, which is the other tightening outer surface 22b, as it moves from the released state (Q) to the locked state (P).

  In the present embodiment, the tension member 130 is formed between the other tightening inner surface 12b and the other tightening outer surface 22b by a rotating operation so that the fixing mechanism 13 has a simple structure and high accuracy. The mode which pushes between them is applied.

  In this embodiment, an operation lever 130e having an operation end 130g projecting outward is provided at the outermost edge of the tension member 130 itself, thereby realizing a light operation feeling utilizing the lever principle. Further, by positioning the operation end 130g from the center of rotation toward the inside of the top plate 1 in the locked state (P), it is effectively avoided that the lever is moved unexpectedly due to an external impact.

  Moreover, in order to support the assembly strength of the leg 2 and the top plate 1 higher and to effectively improve the strength against the load of the top plate 1, in the present embodiment, the fitting outer surface 22 a is separated from the top plate 1. This load is received via the fitting inner side surface 12a.

  In addition to the above-described configuration, in the present embodiment, the top plate support member 23 places the corner of the top plate 1 at the top plate receiving surface 23a so that the legs 2 can support the top plate 1 more firmly. A continuous surface 23b is provided which extends from the outer surface of the top plate 1 to the outer surface of the upper portion of the leg main body 21 in the locked state (P) supported by the head. Thereby, the leg 2 which can support the top plate 1 with a larger area is implement | achieved.

  And in this embodiment, in order to avoid the concentration of the load from the top plate 1 to the local part, the said top-plate support member 23 receives the load from the said recessed part 12 and the said core material 11, respectively.

  Although the embodiment of the present invention has been described above, the specific configuration of each unit is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit of the present invention.

  For example, according to the above-described embodiment, a mode in which the top plate and the leg can be separated is disclosed, but of course, the leg has a folding mechanism that can be folded by rotating around the upper end with respect to the top plate body. The present invention may be applied to. In this case, if the direction in which the tension member is stretched is the direction in which the axis of the pivoting operation extends, it is possible to avoid the movement of the tension member from interfering with the operation of the folding mechanism.

  For example, although the aspect which provided the fixing mechanism which holds a tension member in the top plate side was disclosed in the said embodiment, of course, it is good also as an aspect which provided the fixing mechanism in the leg. Moreover, although the aspect which rotates a tension member horizontally was disclosed in the said embodiment, of course, the aspect which linearly slides a tension member may be sufficient. Regardless of the rotation operation and the slide operation, the operation direction such as the horizontal direction and the vertical direction is not limited. Furthermore, in the above-described embodiment, a mode in which four independent legs are attached to a single top plate is disclosed, but of course, the number and position of the legs to be attached, and a mode in which a horizontal member is separately attached between the legs. I do not disturb. Moreover, the other specific aspect of a top plate or a leg is not limited to the thing of the said embodiment, The thing of various aspects including an existing thing is applicable.

  In addition, the specific configuration of each part is not limited to the above embodiment, and various modifications can be made without departing from the spirit of the present invention.

  The present invention can be used as a table that can be suitably used in an office or the like.
