Description

The present invention relates to a fixture including a base structure and mounting parts mounted on the base structure.

As a technique for mounting the top plate on a base structure such as a sleeve or a leg, the applicant of the present application has described in Patent Document 1 that the locking edge formed at the back of the upper surface of the base structure is attached to the back of the lower surface of the top plate. A synthetic resin fastener provided in the front part of the lower surface of the top plate in the locking hole formed in the front part of the upper surface of the base structure in a state where the provided locking claw is inserted diagonally from the front and engaged. We have previously disclosed a configuration in which the material is dropped and elastically engaged. According to the configuration of Patent Document 1, there is an advantage that the top plate can be easily attached to the base structure.

Japanese Patent No. 3472423

However, in the configuration of Patent Document 1, in order to engage the locking claws of the top plate with the locking edge of the base structure, the top plate is in an oblique position with the back side high, so for example, a shelf or the like is placed on the back side. When attaching the top plate to the base structure installed near the wall, there is no space on the back side (wall side), and there is a concern that the wall may be rubbed and damaged by a shelf or the top plate. Such a problem can occur not only when the top plate is attached to the base structure but also when various mounting parts such as a seat are attached to the base structure.

The technical subject of the present invention is to provide furniture that has been improved by examining the above-mentioned current situation.

The present invention is a fixture including a base structure and a mounting component mounted on the base structure, and the connection between the base structure and the mounting component is such mounting on the base structure. A two-step movement in which the parts are moved in the first direction facing the base structure and then in the second direction intersecting with the first direction, so that the parts are fitted so as to be restricted from coming off and slipping from each other. It is said that it is a combined method.

In the fixture of the present invention, the engagement method is composed of a locking hole formed in one of the base structure and the mounting component, and a locking member provided in the other. The locking member has a retaining claw portion that is hooked and locked by the edge portion of the locking hole, and a slip retaining piece portion that is urged in the direction of fitting into the locking hole. The base structure and the mounting component are connected by fitting the slip stopper piece into the locking hole in a state where the stopper claw portion is caught and locked by the edge portion of the locking hole. You may.

In the fixture of the present invention, the locking member includes, in addition to the retaining claw portion and the slip-preventing piece portion, a releasing operating portion that operates the slip-preventing piece portion in a direction of disengaging from the locking hole. You may have it.

In the fixture of the present invention, in either one of the base structure and the mounting component, the locking member is provided on the front side in the second direction, while the locking member is provided on the back side in the second direction. Correspondingly, a locking claw that is hooked and locked at the edge of the locking hole formed on the other side may be provided.

According to the present invention, for example, when mounting a mounting component having an accessory on a base structure installed near a wall, it is not necessary to hold the mounting component in an oblique posture as in the prior art, and the wall side. Even if there is no space in the wall, there is no risk of scratching the wall with the mounting parts. In other words, furniture can be assembled without damaging surrounding objects or mounting parts. Further, since it is possible to eliminate the force work of holding the mounted parts in an oblique posture as in the conventional technique, the workability of the furniture assembly work is also improved.

In addition, the term "horizontal direction" is used as a general term for the left-right direction or the lateral direction and the front-back direction.

The chair device 1 as a fixture shown in FIGS. 1 to 5 includes a seat body 2 as a mounting component and a base structure 3 that supports the mounting component (seat body 2). In the chair device 1 of the first embodiment, two seat bodies 2 are mounted side by side on the base structure 3 in the left-right direction. The seat body 2 has a seat portion 4 on which a person sits and a panel 5 erected on one side of the seat portion 4. A cushion body 5a is provided on the surface of the panel 5 (the surface facing the seat 4). The panel 5 of the first embodiment is a cushion panel having a cushion body 5a, and has a plate-like portion protruding higher (higher in height) than the cushion body 5a. The seat body 2 constitutes mounting parts, but is not limited to seat-related parts, and is a concept that includes various parts that are used by being attached to a base structure such as a top plate or a shelf.

As shown in FIGS. 4 and 5, each seat 2 is standardized by being configured in a square shape having the same size in a plan view. That is, each seat 2 has a square shape in a plan view with the panel 5 attached to the seat 4. In addition, in this specification, a wording such as a square shape, a rectangular shape or a rectangular shape is a concept including a corner portion having a rounded shape or a chamfered shape.

As shown in FIGS. 1 to 5, the base structure 3 has a rectangular frame-shaped underframe 6 in a plan view and four leg columns 9 that support four corners of the underframe 6. .. The underframe 6 is composed of a pair of long frames 7 and a pair of short frames 8, and the long frame 7 and the short frame 8 are both made of metal and formed in a hollow square shape. By welding adjacent long frames 7 and short frames 8 so that each longitudinal end of the long frame 7 constitutes a corner portion of the base structure 3, a rectangular frame-shaped underframe 6 in a plan view is formed. It is formed. Details will be described later, but in the first embodiment, the upper end side of the corresponding leg support 9 is detachably attached to each corner of the underframe 6, that is, to each of the longitudinal ends of both long frames 7. ..

The connection between each seat 2 and the base structure 3 is a second direction in which each seat 2 is moved in the first direction facing the base structure 3 with respect to the base structure 3 and then intersects with the first direction. It is an engagement method that fits so that the pull-out and slippage are regulated by the two-step movement. As the engagement method of the first embodiment, a locking hole 10 formed in one of the base structure 3 and each seat 2 and a locking member 11 and a locking claw 12 provided in the other are used. Consists of.

The engagement method of the first embodiment is a two-step movement in which each seat 2 is moved downward with respect to the base structure 3 as the first direction, and then moved in the back direction as the second direction. It fits in well. In this case, a locking hole 10 is formed in the base structure 3, and a locking member 11 and a locking claw 12 are provided in each seat 2. Of course, the locking hole 10 may be formed on the seat body 2 side, and the locking member 11 and the locking claw 12 may be provided on the base structure 3 (underframe 6) side.

That is, as shown in FIGS. 3 to 5, a plurality of upward opening-shaped locking holes 10 are formed at appropriate intervals along the longitudinal direction on the upper surface of each long frame 7 in the underframe 6. In the first embodiment, eight locking holes 10 having a square shape in a plan view are formed on the upper surface of each long frame 7.

Locking claws 12 (FIG. 2) that are hooked and locked to the edges of the corresponding locking holes 10 in the long frame 7 on the back side at the two corners of the lower surface of the seat 4 of each seat 2 near the panel 5 (FIG. 2). , FIG. 4, FIG. 5, FIG. 9 and FIG. 11) are fastened with screws 13 from below. The tip claw side of each locking claw 12 projects toward the back. Since the locking claw 12 of the first embodiment is made of synthetic resin, the locking claw 12 is hooked and engaged with the edge of the corresponding locking hole 10 in the long frame 7 on the back side. It is possible to suppress the possibility that the locking claw 12 hits the edge of the 10 and generate an abnormal noise, and the quietness is excellent. A pair of upward protrusions 12a are formed on the upper surface of the locking claw 12. By fitting these upward protrusions 12a on the lower surface of the seat portion 4, the posture deviation of the locking claw 12 is prevented.

At the two corners of the lower surface of the seat portion 4 of each seat body 2 on the side facing the panel 5 (opposite side), the locking member 11 (which engages with the corresponding locking hole 10 in the long frame 7 on the front side) ( 2 and 4 to 8, 10 and 12) are fastened with screws 13 from below. Each locking member 11 is fitted into a retaining claw portion 11b that is caught and engaged with the edge portion of the locking hole 10 in the long frame 7 on the front side and a locking hole 10 into which the retaining claw portion 11b is fitted. It has a slip prevention piece portion 11c that is urged in the direction (downward direction). Further, the locking member 11 of the first embodiment has a releasing operation portion 11d for operating the slip prevention piece portion 11c in a direction of disengaging from the locking hole 10 into which the locking member 11c is fitted. The tip claw side of the retaining claw portion 11b projects toward the back.

As shown in FIGS. 10 and 12, the slip prevention piece portion 11c is fitted in the base portion 11a of the locking member 11 so as to be vertically movable by utilizing the elasticity of the spring 11e. By the vertical movement, the lower side of the slip prevention piece portion 11c is configured to appear and disappear from the downward hole formed in the base portion 11a of the locking member 11. The release operation unit 11d is fitted into the base portion 11a of the locking member 11 so as to be laterally movable. By the lateral movement, the tip side of the release operation portion 11d is configured to appear and disappear from the lateral hole formed in the base portion 11a of the locking member 11. In addition, in the type in which the mounting component is placed and fixed on the base structure, it is also possible to adopt a configuration in which the slip-preventing piece portion 11c moves downward by its own weight without using the elasticity of the spring 11e.

Further, in the first embodiment, when the release operation portion 11d is pushed with a finger, the tip inclined portion of the release operation portion 11d comes into contact with the inner inclined surface of the lateral hole formed in the slip prevention piece portion 11c, and the elasticity of the spring 11e is increased. It is configured to raise the slip prevention piece 11c against the above (see FIGS. 12 (a) and 12 (b)).

Since the locking member 11 of the first embodiment is made of synthetic resin, when the locking member 11 is engaged with the corresponding locking hole 10 in the long frame 7 on the front side, the edge portion of the locking hole 10 is engaged. It is possible to suppress the possibility that the retaining claw portion 11b and the slip-preventing piece portion 11c may hit each other to generate an abnormal noise, and it is excellent in quietness like the locking claw 12. A pair of upward protrusions 11f are formed on the upper surface of the base portion 11a of the locking member 11. By fitting these upward protrusions 11f into the lower surface of the seat portion 4, the posture deviation of the locking member 11 is prevented.

The locking claw 12 of the first embodiment is a form in which the slip prevention piece portion 11c, the release operation portion 11d, and the spring 11e are removed from the locking member 11 of the first embodiment. That is, in the second embodiment, the locking claw 12 and the retaining claw portion 11b of the locking member 11 are common parts. It is not essential that these are common parts, but it is preferable because the number of parts can be reduced by standardization.

As shown in FIGS. 4 and 5, the locking members 11 and the locking claws 12 at the four corners of the lower surface of the seat 4 in the seat 2 are located on the diagonal DIs of the seat 2 in a plan view, respectively. ing. In the first embodiment, the seat body 2 is arranged on the underframe 6 in a predetermined mounting direction, and the locking member 11 or the locking claw 12 is engaged with the corresponding locking hole 10. It is possible to change the mounting direction of each seat 2 to the base structure 3 in four horizontal directions (four directions in front, back, left and right). In this case, since each seat 2 is configured and standardized in a square shape of the same size in a plan view, the presence of the panel 5 does not interfere even if the mounting orientation is changed, and the base structure 3 remains as it is. Can be attached to.

The locking holes 10 on the upper surfaces of the longitudinal ends of both long frames 7 face the leg braces 14 (see FIGS. 10 to 12) fixed in the long frames 7 by welding. Further, a leg mounting hole 15 having a downward opening shape is formed on the lower surface of each of the longitudinal ends of both long frames 7. As shown in FIGS. 10 to 12, the legs are screwed from above through the locking holes 10 and the leg plates 14 in a state where the upper end side of the leg columns 9 is fitted into the leg mounting holes 15. The columns 9 are detachably fastened to each corner of the underframe 6.

In the above configuration, the seat body 2 is attached to the base structure 3 by, for example, the following procedure. That is, the locking member 11 and the locking claw 12 on the lower surface side of the seat portion 4 in the seat body 2 are seated above the underframe 6 of the base structure 3 so as to face the corresponding locking holes 10 in each long frame 7. Carry body 2 (see FIGS. 10 (a) and 11 (d)). In this case, the seat body 2 is moved above the underframe 6 so that the locking members 11 are located on the front side and the locking claws 12 are located on the back side.

Then, the seat body 2 is moved downward facing the underframe 6, and the retaining claw portion 11b and the locking claw 12 of the locking member 11 are inserted into the corresponding locking holes 10 (FIG. 10). (B) and FIG. 11 (e)). Then, the slip-preventing piece 11c of the locking member 11 comes into contact with the upper surface of the edge of the locking hole 10, rises against the elasticity of the spring 11e, and immerses itself in the base 11a of the locking member 11 ( See FIG. 10 (b)).

Next, the seat body 2 is pushed inward, and the retaining claw portion 11b and the locking claw 12 of the locking member 11 are hooked and engaged with the corresponding edge portions of the locking holes 10 (FIG. 10 (c)). And FIG. 11 (f)). Then, the slip-preventing piece 11c of the locking member 11 faces the gap of the locking hole 10 formed on the front side of the retaining claw portion 11b of the locking member 11, and the slip-preventing piece 11c It descends due to the restoring force of the spring 11e and fits into the gap of the locking hole 10 described above (see FIG. 10C). As a result, the seat body 2 and the base structure 3 are connected.

In this case, the tip claw side of the retaining claw portion 11b of the locking member 11 and the locking claw 12 regulate the pull-out (rattling) in the vertical direction, and the locking claw portion 11b and the main body side of the locking claw portion 11 The slip prevention piece 11c regulates the horizontal slip (play). Incidentally, the gap of the locking hole 10 formed on the front side of the locking claw 12 remains as it is (see FIG. 11 (f)).

On the contrary, when the seat body 2 is removed from the base structure 3, for example, the procedure is as follows. That is, by pushing the release operation portion 11d of both locking members 11 on the front side of the lower surface of the seat portion 4 in the seat body 2 with a finger, the slip prevention piece portion 11c is moved up against the elasticity of the spring 11e. Then, the slip prevention piece 11c is pulled up from the gap of the corresponding locking hole 10 (see FIG. 12A).

Next, the seat body 2 is pulled toward the front, and the retaining claw portion 11b and the locking claw 12 of the locking member 11 are displaced from the corresponding edges of the locking holes 10 to be disengaged (FIG. 12 (FIG. 12). b) See). Then, the slip-preventing piece portion 11c of the locking member 11 rides on the upper surface of the edge portion of the corresponding locking hole 10 and comes into contact with the locking member 11, and ascends against the elasticity of the spring 11e to move inside the base portion 11a of the locking member 11. Immerse yourself in (see FIG. 12 (b)). In this state, the finger may be released from the release operation unit 11d. Here, although the behavior of the locking claw 12 side is not shown, the state is the same as that shown in FIG. 11 (e).

Then, the seat body 2 is moved upward so as to face the underframe 6, and the retaining claw portion 11b and the locking claw 12 of the locking member 11 are pulled up from the corresponding locking holes 10 (FIG. 12 (c)). )reference). As a result, the connection between the seat body 2 and the base structure 3 is released. Here, the state of the locking claw 12 side is the same as that shown in FIG. 11 (d).

According to the above configuration, the seat body 2 is moved in the first direction (downward direction) facing the base structure 3 with respect to the base structure 3, and then in the second direction (backward direction) intersecting the first direction. Since it is an engaging system that fits together so that it is restricted from coming off and slipping by two steps of movement, for example, a panel 5 etc. is attached to the back side of the base structure 3 installed near the wall. When attaching the seat body 2 holding an object, it is not necessary to hold the seat body 2 in an oblique posture as in the conventional technique, and even if there is no space on the back side (wall side), the seat body 2 can be used. There is no risk of rubbing and damaging the wall. That is, the chair device 1 can be assembled without damaging the surrounding objects. Further, since it is possible to eliminate the force work of holding the seat body 2 in an oblique posture as in the conventional technique, the workability of the assembly work of the chair device 1 is also improved.

Further, in a state where the retaining claw portion 11b of the locking member 11 is caught and locked by the edge portion of the corresponding locking hole 10, the slip-preventing piece portion 11c of the locking member 11 is fitted into the locking hole 10. When the structure in which the base structure 3 and the seat body 2 are connected is adopted, the locking member 11 is prevented from coming off (rattling) on the tip claw side of the retaining claw portion 11b, and the locking member 11 is prevented from coming off. Misalignment (rattling) is regulated between the main body side of the claw portion 11b and the slip prevention piece 11c, and the regulation direction can be shared between the slip prevention claw portion 11b and the slip prevention piece 11c, ensuring the connection strength. It has the advantage of being easy.

Further, in either the base structure 3 or the seat body 2, the locking member 11 is provided on the front side in the second direction (back direction), while the locking member 11 is provided on the back side in the second direction (back direction). If a locking claw 12 that is hooked and locked is provided on the edge of the locking hole 10 formed on the other side, the locking claw 12 can have a simpler structure than the locking member 11, and thus is connected. It is possible to reduce the cost of parts while maintaining the strength. Further, since the locking member 11 has a releasing operation portion 11d for operating the slip prevention piece portion 11c in the direction of disengaging from the corresponding locking hole 10, the work of removing the seat body 2 from the base structure 3 is performed. That is, the disassembling work of the chair device 1 can be easily performed. In addition, installation / removal work is possible without using special tools, and the seat body 2 can be freely rearranged, such as by changing the mounting orientation. In these respects, the workability of the chair device 1 assembly / disassembly work is also possible. Contribute to improvement.

Further, as shown in FIG. 18, extension connecting tools 40 can be attached not only to each corner of the underframe 6 but also to two locations on the outer side in the horizontal direction not only in each corner of the underframe 6 but also in the middle of the length of each long frame 7. Horizontally open screw insertion holes 7b are formed at two locations in the middle of the longitudinal portion of each long frame 7. The underframe 6 is held by the holding portion 41 of the extension connector 40, and the screw 43 from the inside of the underframe 6 is screwed into the nut portion 42 of the extension connector 40 through the screw insertion hole 7b of each long frame 7. As a result, the extension connector 40 is detachably fastened to the two places in the longitudinal portion of the long frame 7 in the underframe 6.

If the extension connector 40 does not have the holding portion 41, the load is concentrated on the screw 43, and it is difficult to withstand the load. Therefore, the relative displacement between the underframes 6 is regulated by the holding portion 41 of the extension connector 40, and the holding portion 41 receives the vertical load so that the screw 43 is not loaded in the vertical direction. It has become. Further, when the leg support 9 is attached to the extension connecting tool 40 (details will be described later), the load can be distributed and received by the extension connecting tool 40 and the leg support 9 due to the presence of the lower holding portion 41.

A locking hole 10 is formed on the upper surface of the extension connector 40 (see FIG. 20). That is, it is possible to engage the locking member 11 and the locking claw 12 with the extension connector 40. The locking hole 10 of the extension connector 40 faces the inner plate portion 44 inside the extension connector 40. A leg mounting groove 45 is formed on the lower side of the extension connector 40. With the upper end side of the leg support 9 fitted in the leg mounting groove 45, the leg support 9 can be attached to and detached from the extension connector 40 by screwing the screw 46 from above through the locking hole 10 and the inner plate portion 44. Is fastened to. Therefore, each leg support 9 can be replaced with either the underframe 6 or the extension connector 40.

As shown in FIGS. 18 and 21, when the long seat body 33 is mounted on the underframe 6, a spacer 47 is interposed between the underframe 6 and the long seat body 33. Each spacer 47 is made of synthetic resin, and has a main body portion 47a having a rectangular shape in a plan view, and a fitting portion 47b integrally formed with the main body portion 47a with a phase shifted by approximately 45 ° from the main body portion 47a. There is. After fitting the fitting portion 47b of the spacer 47 into the locking hole 10 in which the locking member 11 and the locking claw 12 do not engage, the spacer 47 is locked by rotating the main body portion 47a by approximately 45 °. It is attached to 10.

As shown in FIGS. 17, 18 and 22, the panels 5 of the adjacent seats 2 are connected to each other by a joint piece 48 at the upper part of the plate-shaped portion in order to prevent slippage. The joint piece 48 is arranged so as to straddle the upper part of the plate-shaped portion of the adjacent panel 5. Both ends of the length of the joint piece 48 are fixed to the plate-shaped portion of each panel 5 with screws 49. A joint cover 50 is detachably attached to the joint piece 48 to which the screw 49 is fixed to prevent the screw 49 from being exposed.

The configuration of each part in the present invention is not limited to the illustrated embodiment, and various changes can be made without departing from the spirit of the present invention. For example, in the connection between the mounting component and the base structure, the mounting component is moved upward as the first direction with respect to the lower surface instead of the upper surface of the base structure, and then moved in the horizontal direction as the second direction. It may be a hanging type that fits by moving in stages, or it may be a second direction after moving the mounting component in the horizontal direction as the first direction with respect to the surface of the base structure extending in the vertical direction. It may be a horizontal type (a form such as wall mounting) that fits by two steps of moving upward or downward. Further, the locking hole may be provided on the mounting component side, and the locking member and the locking claw may be provided on the base structure side.

Further, the structure of the base structure does not have to be limited to the one including the underframe and the leg columns as in the above embodiment, and various structures such as beams and walls can be adopted. It is not indispensable to standardize the mounting parts by forming them into a square shape having the same size in a plan view as in the seat body 2 of the above embodiment.
