Description

  The present invention provides a member mounting structure in which an end member is attached to an end surface of a member main body such as a small edge, and an accessory member such as a hanging sign or a rotary hinge can be simultaneously attached to the member. It is related to the table using.

  When manufacturing furniture and fixtures with different standards using members of different lengths, a resin body extruded body or sheet metal roll molded body is appropriately cut to produce a member body of different length, In order to conceal the forehead and the like appearing on the end face of the member main body, it is customary to mount an end member to form a member having an appropriate length. And such a member is attached to a furniture main body via attachment members, such as a hanging sign and a link.

  As an example, in a top-and-bottom undulation-type conference table, a curtain plate is used to shield the lower limb space, but the curtain plate is composed of a main body and an end member to accommodate the difference in length. In order to rotate and house the plate in accordance with the movement of the top plate, attached members such as a hanging sign and a rotating hinge are attached.

In the past, such an attachment member was fastened to the curtain plate with a wood screw, a tapping screw or the like. Therefore, in addition to the work of attaching the end member to the curtain plate body, a screw or the like was used for the curtain plate. The operation of attaching and fixing the attachment member has to be performed, and it takes time because of the large number of man-hours, and there is a problem that the appearance is impaired because screws and the like are exposed on the curtain plate. Furthermore, there is a case where the curtain plate is kicked, etc., and it may be necessary to replace it. However, if the screw once tightened is removed and retightened, the mounting state becomes unstable due to the sag in the screw hole or the like. I had it.

As a reference for solving such problems, for example, as shown in Patent Document 1, a curtain plate is composed of an intermediate member and end members joined to the left and right ends of the intermediate member. A mounting structure has been proposed in which a protrusion having a left and right axial hole is integrally provided at the joint between the intermediate member and the end member, and a link or the like is pivotally attached to the axial hole.
Japanese Patent No. 334595

However, if a structure in which one end of a link or the like is pivotally attached to the protrusion by such a structure is used, when attaching the other end of the link or the like to the leg column of the conference table, the protrusion must be in the nearest position corresponding to the leg column. It becomes essential. Since the protrusion is located at the boundary between the intermediate member and the end member and is integrally formed with one of the members, the dimension of the intermediate member that forms the main body of the curtain plate with respect to the separation distance between the left and right leg columns is large. For example, it is difficult to use the same curtain plate between different conference tables with different separation distances between the left and right leg posts, and due to circumstances such as dealing with other parts on the same conference table. It is also difficult to change the mounting position where the curtain must be attached to a different part of the table.

  It is an object of the present invention to provide a member mounting structure that can effectively eliminate such problems and a table using the same.

  In order to achieve this object, the present invention takes the following measures.

That is, the member mounting structure of the present invention temporarily holds the attached member in a portion other than the end surface of the member main body, and the end member is attached to the end surface of the member main body directly or in the inner space where the surface of the member main body is not exposed. The end member is engaged so that it cannot be pulled out, and the attachment member can be fixed to the temporarily held position by the end member.

If it does in this way, since an end member will engage with a member main body by itself, and an attachment member will be fixed by an end member, according to the present invention, only by inserting an end member in the state where an attachment member was temporarily held. The attachment of both members to the member main body can be completed without performing a screwing operation or the like. For this reason, the number of manufacturing steps and the number of parts can be reduced, the assembly is facilitated, and the appearance can be kept good. In addition, the attachment position of the attachment member does not necessarily need to be close to the end member, and the attachment position of the attachment member is set to a position away from the end member, for example, on the condition that the end member can be engaged with the attachment member. Therefore, according to the present invention, it is possible to effectively improve the degree of freedom of attachment of the accessory member.

When the member main body has a space that is open to the end surface and into which the end member is inserted, an opening is formed in a part of the wall facing the space, and the opening is attached to the opening in a state of concealing the opening. Is effective so that the base end portion is mounted on the insertion path of the end member, and the insertion end of the end member is engaged with the base end portion.

As a specific embodiment in this case, the base end portion of the attachment member is semi-sunk into the opening, and the attachment member is displaced in the thickness direction on the wall of the member body by displacing the attachment member in a direction perpendicular to the settling direction. And the insertion end of the end member is engaged with the base end portion of the attachment member at that position to restrict the displacement of the attachment member in the reverse direction.

In particular, an engagement portion that can be elastically deformed is provided on the insertion end side of the end member, and the engagement portion is temporarily elastically deformed and then restored to be engaged with the member body so that it cannot be removed. Is desirable.

In order to ensure the mounting state of the member, and to make it possible to easily cope with the need for replacement without causing problems such as screw hole sag, the engagement portion has a twisted shape. In this way, the engaging part engages with the engaged part more deeply with respect to the movement in the removing direction through this return, and the engagement is prohibited by an external operation. It is desirable to provide an operation part in a part of the member main body for elastically deforming the part to disengage the return from the member main body and release the removal prohibition state.

Since the present invention is configured as described above, it can be extremely useful when the member main body is an extruded molded body, a roll molded body, or the like that is molded into an equal cross section.

In addition, as a preferable application example of such a member mounting structure, a curtain plate is used as an applied member, and an attachment member for mounting the curtain plate is temporarily held in a portion other than the end surface of the member main body, and the end surface of the member main body. An end member is engaged so that it cannot be pulled out in an inner space that is not exposed on the surface of the member main body, and the end member is fixed to a position where the attached member is temporarily held by the end member. A table that is completed by attaching to a predetermined position via an attachment member.

Since the present invention has the configuration described above, it is possible to reduce the number of man-hours and the number of parts by eliminating the screwing work when attaching the accessory member while configuring various members, and also, the member can be shared and the member can be freely attached. It is possible to provide a new and useful member mounting structure and table that can be improved effectively.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

This embodiment relates to a member mounting structure around the curtain plate 1 used to shield the lower limb space in the top-plate undulating conference table T shown in FIG.

On the other hand, the curtain plate 1 is attached to a top plate lower member 5 such as a side plate or a shelf plate that rotates with the top plate 2 via a hanging sign 4a around the horizontal axis m1, and the lower edge side is connected to the rotary hinge 4b and It is attached to the leg support 3 via the link 6 around the horizontal axis m2, and in conjunction with the rotation of the top board 2, it is separated from the rear of the leg support 3 at the use position of FIG. It is made to move to the site | part which does not become obstruct | occluded by making it approach to the leg support | pillar 3 in the folding position of FIG.

As shown in FIG. 2, the curtain plate 1 is composed of a member main body 11 and an end member 12 as shown in FIG. 2. When the end member 12 is attached to the member main body 11, the hanging sign 4a described above is formed. The rotary hinge 4b can be simultaneously fixed to the curtain plate 1 as an attachment member for attaching the curtain plate.

The member main body 11 is formed in an equal cross section by resin molding and is a hollow body surrounded by the front and rear face plate portions 11a and the upper and lower end faces 11b, and a plurality of ribs 11c extending in the width direction are intermittently formed vertically. By doing so, the inside is divided into a large number of spaces S, and each space S is open to the left and right end faces 11d which are small openings. Then, in the vicinity of the end surface 11d, the face plate portion 11a surrounding the space S1 is punched out from the specific space S1 on the upper edge side and the lower edge side of the one face plate portion 11a to form an opening hole 11e. The opening hole 11e has an H shape in which a pair of widened portions 111e are connected by a narrow portion 112e.

On the other hand, the end member 12 has an end surface 12d having a shape substantially matching the left and right end surfaces 11d of the member main body 11, and corresponds to the specific space S1 of the member main body 11 from the end surface 12d inward. Insertion pieces 12a and 12b projectingly inserted into portions corresponding to some other spaces S2 and the insertion portions 12a and 12b at least in the corresponding spaces S1 and S2, respectively. The end surface 12d of the end member 12 is brought into contact with the end surface 11d of the member main body 11 while being closely inserted in the thickness direction of the member 11. Then, as shown in FIGS. 3 to 6, the insertion piece 12a inserted into the specific space S1 is pressed by the face plate portion 11a that surrounds the space S1 during the insertion process and is inserted into the widened portion 111e of the opening hole 11e. An engaging portion 120 that can be restored and has a resin spring action is provided, and a twisted return 120 a is formed on the abdominal surface of the engaging portion 120.

The hanging sign 4a and the rotating hinge 4b can be inserted into the opening hole 11e with an appropriate thickness on the back surface of the top plate part 40 and a back surface of the top plate part 40 that can close the opening hole 11e. It has a common base structure composed of the provided base end portion 41 and is integrally formed on the upper surface of the top plate portion 40. The base end portion 41 includes a block-shaped protruding portion 411 formed at a portion corresponding to the widened portion 111e and a protrusion 412 formed at a portion corresponding to the narrow path portion 112e. A groove 411a parallel to the top plate portion 40 is provided along the back surface of the top plate portion 40 on one end side (a portion located on the side opposite to the end surface 11d) of each projecting portion 411, and an arrow in FIGS. As shown by X1, at the stage where the base end portion 41 is semi-sunk into the opening 11e and enters the insertion path of the end member 12, first, the base end vicinity portion 411a (see FIG. 4) of the protruding portion 411 is the opening hole 11e. The widened portion 111e is positioned so that it cannot move in the vertical direction. Then, by displacing the whole from the position in a direction (center side of the member main body 11) perpendicular to both the settling direction and the positioning direction as shown by the arrow X2, the groove as shown in FIGS. 411a is fitted to the thickness of the face plate portion 11a so that it cannot be peeled off from the face plate portion 11a, and at the same time, the opening hole 11e is closed by the top plate portion 40. A rectangular recess 40a facing the widened portion 111e of the opening hole 11e on the side close to the end surface 11d at the displaced position is formed in the back surface of the top plate portion 40. The concave portion 40a becomes an operation margin when an engaging portion 120 described later enters the widened portion 111e of the opening 11e.

The insertion pieces 12a and 12b of the end member 12 described above are inserted into the corresponding spaces S1 and S2, respectively, and the engaging portion 120 provided on the insertion piece 12a inserted into the specific space S1 is inserted into the inside of the face plate portion 12a. After the elastic deformation of the opening 12e, it is restored at the widened portion 111e of the opening 12e, and the twisted return 120a is engaged with the opening edge of the widened portion 111e so that it cannot be removed. It has been realized. At that time, the insertion end 12x of the end member 12 is attached to the engaged portion 41x formed at the corresponding portion of the protruding portion 411 of the base end portion 41 that is integral with the hanging sign 4a and the rotating hinge 4b. The hanging sign 4a and the rotating hinge 4b are fixed so as not to be displaced in the reverse direction. The insertion end 12x and the engaged portion 11x are engaged in a step shape as shown in the figure, and the step structure is set so that the pulling force toward the front of the hanging sign 4a and the rotating hinge 4b is pressed by the end member 12. It is.

An insertion hole 40p, which is an operation portion into which a pressing tool with a sharp tip for pressing the engaging portion 120 can be inserted, is provided at a position corresponding to the concave portion of the top plate portion 40, and is engaged by the pressing tool inserted from here. The portion 120 is elastically deformed so that the engagement with the opening 11e can be released.

As described above, in the member mounting structure of the present embodiment, the curtain plate 1 is used as an applied member, and the hanging sign 4a and the rotating hinge 4b, which are attached members, are temporarily held in a portion other than the end surface 11d of the member main body 11. The end member 12 is engaged with the end surface 11d of the member main body 11 so that the end member 12 cannot be removed in the inner space that is not exposed on the front surface of the member main body 11, and the end sign 12 temporarily attaches the hanging sign 4a and the rotary hinge 4b. It can be fixed at the held position.

If it does in this way, since end member 12 will engage with member main part 11 by itself, hanging sign 4a and rotation hinge 4b will be fixed by end member 12, according to this embodiment, hanging sign 4a and rotation The attachment of the two members 12, 4a (or 12, 4b) to the member main body 11 can be completed by simply attaching the hinge 4b and inserting the end member 12 without performing screwing or the like. For this reason, the number of manufacturing steps and the number of parts can be reduced, the assembly is facilitated, and the appearance can be kept good. Moreover, the attachment location of the hanging sign 4a and the rotating hinge 4b is not necessarily close to the end member 12, and the condition that the end member 12 is engaged with the proximal end portion 41 of the hanging sign 4a and the rotating hinge 4b. As long as it is satisfied, the mounting position of the trillion number 4a and the rotating hinge 4b can be set at a position away from the end member 12, and the degree of freedom of mounting of the hanging sign 4a and rotating hinge 4b according to this embodiment. It is possible to improve both effectiveness and effectiveness.

In addition, as described above, the present embodiment has a space S in which the member main body 11 is opened to the end surface 11d and the end member 12 is inserted, and one of the face plate portions 11a serving as a wall facing the specific space S1. An opening 11e is formed in the part, and the hanging sign 4a and the rotating hinge 4b are mounted on the opening 11e in a state of concealing the opening 11e so that the base end part 41 is positioned on the insertion path of the end member 12 It is. Then, the insertion end of the end member 12 is abutted against and engaged with the base end portion 41. For this reason, it becomes possible to change easily the attachment position of the hanging sign 4a and the rotation hinge 4b depending on where the opening 11e is formed. In this case, it is easy to cope with such a new situation by changing the length of the end member 12 to the insertion end 12x or by interposing an appropriate spacer or the like.

As a specific structure of the present embodiment, the hanging sign 4a and the base end portion 41 of the rotary hinge 4b are semi-sunk into the opening 11e, and are displaced in the direction perpendicular to the settling direction from the position, thereby hanging sign 4a. The rotating hinge 4b is engaged with the face plate portion 11a, which is the wall of the member main body 11, in the thickness direction, and the end member 12 is engaged with the engaged portion 11x of the base end 11 of the hanging hinge 4a or the rotating hinge 4b at that position. The insertion end 12x is engaged to regulate the displacement of the hanging sign 4a and the rotating hinge 4b in the reverse direction. For this reason, peeling in the thickness direction of the hanging sign 4a and the rotating hinge 4b can be prevented by widely using the face plate portion 11a. In particular, the insertion end 12x and the engaged portion 11x are engaged in a staircase shape as described above, and the staircase structure is in a direction in which the pulling force toward the front of the hanging sign 4a and the rotating hinge 4b is pressed by the end member 12. Since it is what was set, the reliable attachment state which does not depend only on the intensity | strength of the faceplate part 11a is realizable.

In addition, an engaging portion 120 that can be elastically deformed is provided on the insertion end 12x side of the end member 12, and the engaging portion 120 is temporarily elastically deformed and then restored so that it cannot be removed from the member main body 11. Since the engagement is made, the end member 12 can be easily and reliably attached with one touch without using a tool.

In particular, the engagement portion 120 is provided with a twist-like return 120a, and the engagement portion 120 engages with the member main body 11 more deeply with respect to the movement in the removal direction through the return 120a and prohibits removal. In addition, since the engaging portion 120 is elastically deformed by an external operation to disengage the return 120a from the member body 11 and release the removal prohibition state, a part of the member body 11 is provided. The mounting state of the hanging sign 4a and the rotating hinge 4b can be ensured, and when there is a need to replace the curtain plate 1 or the like, it is easy to hang without causing problems such as screw hole sag. It is possible to deal with replacement of the curtain plate 1 by attaching / detaching the trillion number 4a and the rotating hinge 4b.

And since the conference table T of this embodiment utilizes such a member mounting structure, for example, the same curtain plate 1 is used together between different conference tables having different distances between the left and right leg columns 3. The screen 1 is attached to the conference table T due to circumstances such as usage, a mode in which the screen 1 wider than the separation distance of the leg columns 3 is attached, and the other conference on the same conference table T. It is possible to easily realize an aspect such as a change in the attachment position when it must be attached to a part other than the leg support 3 (for example, a frame connecting the leg support).

The specific configuration of each unit is not limited to the above-described embodiment.

For example, even if the member main body is not a complete hollow body, the application range of the present invention does not change unless the engaging portion between the end member and the attached member is exposed to the front side where it is easily visible. Therefore, the present invention can be similarly applied to a curtain plate formed by roll-molding a sheet metal.

In addition, if the attached member semi-sedimented in the above-described embodiment is displaced toward the end surface side of the member main body and the insertion end of the end member is engaged with the displaced position, the end member is indirectly connected via the attached member. The end member and the attached member can be made to function as a counterpart retaining member.

  Furthermore, when a shelf board or a pedestal is composed of a member main body and an end member, and a bracket or the like for attaching the shelf board or the pedestal to the top board or frame is attached to the member main body as an accessory member, these It is also effective to apply the present invention between the member main body, the end member, and the accessory member.

  Other configurations can be variously modified without departing from the spirit of the present invention.
