Description

The present invention relates to furniture with a top plate in which a wiring opening is provided in the top plate.

For furniture with a top plate such as a table used in an office, it is necessary to open a wiring opening in the top plate so that the power cable, LAN cable (network cable), or USB port cable for power supply can be pulled out on the desk. There are many. Since this wiring opening has a certain size for inserting and removing connectors, it is usually closed with a cover.

In general, a frame body extending along the inner circumference thereof is attached to the wiring opening, and the cover is often detachably attached to the frame body. As described above, in Patent Document 1, as an example of the device, a pair of front and rear covers are arranged in one wiring opening, and the two covers are attached to the frame in a rotatable state, so that the covers are not removed. A configuration that can be opened and closed is disclosed.

Further, as furniture with a top plate, a fixture unit having a terminal connection portion such as a power plug insertion hole is arranged in an opening formed in the top plate so that the posture can be changed (for example, a patent). See Document 1). In such furniture with a top plate, the connector unit is positioned between a usage posture in which the terminal connection portion is located above the top plate and a storage posture in which the terminal connection portion is located below the top surface of the top plate. It is provided so that it can be changed. When the connector unit is in the retracted position, the top surface of the connector unit is set to be at the same height as the top surface of the top plate, and the top surface of the top plate is flat.

Therefore, the connector unit is provided so that the posture can be changed between the usage posture and the storage posture.

Japanese Unexamined Patent Publication No. 2016-87243 JP-A-2019-63144

In the furniture with a top plate disclosed in Patent Documents 1 and 2, the main body of the cover or connector unit that closes the opening provided in the top plate is a synthetic resin molded product, and the top surface thereof is made of synthetic resin. .. Such a cover or connector unit is good because if the upper surface (design surface) of the top plate of furniture is formed of a melamine decorative plate, a veneer, or the like, a sense of unity with the upper surface of the top plate 1 cannot be obtained. There was a problem that the design could not be obtained. Further, the cover or connector unit made of synthetic resin is often formed in a single color such as black or white, and the degree of freedom in designing the top surface thereof is low.

The present invention has been made to improve such a situation, and improves the degree of freedom in designing the top surface of the lid member in furniture with a top plate provided with a lid member for closing the wiring opening provided in the top plate. The purpose is to make it.

The furniture with a top plate of the present invention is furniture with a top plate in which a lid member for closing at least a part of the wiring opening is attached to a wiring opening provided in the top plate, and the lid member is a top surface portion thereof.

In the furniture with a top plate of the present invention, the lid member that closes at least a part of the wiring opening includes a decorative plate adhered to the upper surface of the top surface portion. By forming it with a material having the same design surface as the decorative plate for the top plate attached to the (upper surface), it is possible to give a sense of unity between the top plate and the lid member, and the appearance is improved. It is also possible to improve the design by forming the decorative plate of the lid member with a design surface different from that of the decorative plate of the top plate. Further, since the decorative plate is attached to the top surface of the lid member, even if a hole is formed in the top surface, the hole can be covered with the decorative plate, so that the appearance is not affected. The degree of freedom in designing is increased.

In the furniture with a top plate of the present invention, the upper surface of the decorative plate is arranged at the same height as the upper end portion of the peripheral rib, or is arranged on the upper surface side of the top surface portion from the upper end portion of the peripheral rib. It may be done.

According to such an aspect, the peripheral portion (upper surface corner portion) of the decorative plate of the lid member comes into contact with the user's hand or an article (for example, a notebook computer, a writing tool, etc.) placed on the top plate 1. It is possible to prevent the user from being injured by the hand, and it is possible to prevent the peripheral edge of the decorative board from being damaged and the appearance to be deteriorated.

In the furniture with a top plate of the present invention, for example, the lid member is a synthetic resin cover detachably provided in the wiring opening.

According to such an aspect, even if the cover is made of synthetic resin, by providing a decorative plate on the upper surface of the top surface portion, a cover having a design surface similar to that of the decorative plate for the top plate is formed and the top plate is formed. It is possible to create a sense of unity between the lid member and the lid member, which improves the appearance.

In the furniture with a top plate of the present invention, for example, the lid member is a connector unit provided with a terminal connection portion on one side surface of a main body case made of synthetic resin, and the connector unit is an upper surface of the main body case.

An engaging recess 62 into which the third protrusion 29 of the above is fitted is provided. The engaging recess 62 is formed in a groove shape along the radial direction of the lock piece movement locus 80.

Further, on the left and right outer surfaces of the lock piece 61, a rib-shaped inclined portion 64 that becomes higher toward the engaging recess 62 is provided at a position above the engaging recess 62 along the lock piece moving locus 80. In the inclined portion 64, when the connector unit 12 is rotated upward from the retracted posture (see FIGS. 11 and 13 (A)) from the retracted posture (see FIGS. 11 and 13 (A)), the engaging recess 62 is fitted into the third protrusion 29. The engaging recess 62 is displaced in the direction away from the inner peripheral surface of the frame 9 against the elastic force of the lock piece 61 by sliding contact with the third protrusion 29 (that is, the side approaching the side plate 38). (Displace to).

Further, on the upper end side of the lock piece 61, when the connector unit 12 is in the retracted posture, it is located below the third protrusion 29 of the frame body 9 to regulate the upward rotation of the connector unit 12. A claw 68 is provided. The locking claw 68 includes an elastically deformable arm portion 68a that extends obliquely upward from the base end portion toward the frame body 9. Then, when the connector unit 12 is in the retracted posture, the tip end portion 68b of the arm portion 68a is configured to be located directly below the third protrusion 29.

The locking claw 68 of the lock piece 61 is an intermediate portion of the arm portion 68a before the connector unit 12 is in the retracted posture when the connector unit 12 is rotated downward from the used posture to the retracted posture. Is configured to be in sliding contact with the third protrusion 29 and to displace the tip end portion 68b of the arm portion 68a in a direction away from the inner peripheral surface of the frame body 9 against the elastic force of the arm portion 68a.

On the left and right outer surfaces of the lower part of the lock piece 61, a lower end inclined surface portion is located at a position below the engaging recess 62 and approaches the side plate portion 38 side as the distance from the engaging recess 62 downward along the lock piece movement locus 80. 69 is provided.

Next, the attachment of the connector unit 12 to the frame body 9 and the change of the posture of the connector unit 12 will be described with reference to FIGS. 9 to 13. As described above, the side view substantially U-shaped holding portion 46 is formed integrally with the main body case 15 of the connector unit 12. As shown in FIG. 9, the lower surface portion and the portion rising rearward of the outer peripheral surface of the holding portion 46 are formed as an arc-shaped outer peripheral surface 46a, and the open end of the holding portion 54 of the arc-shaped outer peripheral surface 46a. A first engaging recess 46b is formed on the side of the above, and a second engaging recess 46c is formed on the end of the arcuate outer peripheral surface 46a on the side opposite to the opening end of the holding portion 54, and the first engaging recess is formed. A third engaging recess 46d is formed at an intermediate position between the recess 46b and the second engaging recess 46c. A pair of upper and lower engaging protrusions 46e are provided on the inner peripheral surface of the holding portion 46. On the other hand, the tip of the lock arm 32 is provided with an engaging protrusion 57 that fits into the engaging recesses 46b, 46c, 46d.

As shown in FIG. 9, the connector unit 12 is in a raised position, and the left and right holding portions 46 are aligned with the left and right bearing boss bodies 31 of the frame body 9. Then, as shown in FIG. 10, when the connector unit 12 is pushed downward, a pair of upper and lower engaging projections 46e provided on the inner surface of the holding portion 46 are centered on the tip of the tubular bearing boss body 31. It passes by the side of the bearing boss body 31 while being elastically deformed to the side. Then, when the engaging projection 46e reaches the lower part of the bearing boss body 31, the deformation of the bearing boss body 31 is restored, and the holding portion 54 is rotatably held by the bearing boss body 31. That is, the holding portion 54 can be fitted into the bearing boss body 31 against the elasticity of the bearing boss body 31.

In this state, the engaging protrusion 57 of the lock arm 32 provided on the frame 9 is fitted into the first engaging recess 46b provided on the arcuate outer peripheral surface 46a of the holding portion 46, and the connector unit 12 is formed. The unit top surface 12b stands upright from the tilted state in the usage posture and is in a retracted posture in which the connection port 42 and the USB port 18 (terminal connection portion) are located above the top plate 1 in a substantially vertical state with respect to the top plate 1. Be retained. By setting the connector unit 12 in the retracted posture in this way, a large space can be formed between the connector unit 12 and the frame body 9, and the user can form a large space from above the top plate 1 through the space. The space under the top plate 1 (for example, the wiring duct 7) can be easily accessed. Further, for example, when a clamp metal fitting for attaching an optional item such as a task light or a monitor arm is attached to the edge of the top plate around the wiring opening 6, the connector unit 12 is set to the retracted posture and is attached to the frame body 9. By increasing the space between them, the work of attaching the clamp metal fittings becomes easier and the convenience is improved. Further, since the connector unit 12 is removable from the frame body 9, the wiring opening 6 can be opened larger by removing the connector unit 12 from the frame body 9 at the time of the above work. It will be easier to work.

When the connector unit 12 is rotated downward from the retracted posture, the lower end inclined surface portion 69 provided at the lower left and right outer surface lower ends of the lock piece 61 of the posture holding mechanism 60 provided on the left and right side portions of the connector unit 12 becomes a frame body. It comes into contact with the third protrusion 29 of 9. Further, when the connector unit 12 is rotated downward, the third protrusion 29 enters between the front and rear arcuate ribs 71 and 71 of the lock piece holding portion 70 provided in the posture holding mechanism 60 from below, and the lower end thereof. The main body 63 is elastically deformed so that the inclined surface portion 69 is displaced downward while being in sliding contact with the third protrusion 29, and the lower side of the lock piece 61 is displaced toward the side plate portion 38. Further, as the downward rotation of the connector unit 12 progresses, the engaging recess 62 elastically engages with the third protrusion 29, and the connector unit 12 is held in the used posture (FIGS. 12 and 13 (B), etc.). reference). In the present embodiment, when the connector unit 12 is in the operating posture, the unit top surface 12b of the connector unit 12 is configured to form an angle of approximately 45 degrees with respect to the top surface of the top plate 1.

When the connector unit 12 is in the working posture, the posture holding mechanism 60 positions a pair of front and rear arcuate ribs 71 of the lock piece holding portion 70 in front of and behind the third protrusion 29 provided on the frame body 9. The movement of the connector unit 12 in the front-rear direction can be regulated. As a result, the connector unit 12 does not come off from the frame 9 when the power plug or the USB cable is inserted into or removed from the connection port 42 or the USB port 18.

As shown in FIG. 12, when the connector unit 12 is in the operating posture, the engaging protrusion 57 of the lock arm 32 provided on the frame 9 fits into the third engaging recess 46d of the holding portion 54. It contributes to maintaining the posture of the connector unit 12 in the used state and suppresses rattling of the connector unit 12.

When the connector unit 12 in use is rotated downward, the engaging recess 62 disengages downward from the third protrusion 29 against the elasticity of the main body 63 of the lock piece 61, and is above the engaging recess 62. The inclined portion 64 provided in the above passes through the side of the third protrusion 29 while sliding in contact with the third protrusion 29, and then the base end of the arm portion 68a of the locking claw 68 is laterally attached to the third protrusion 29. The department arrives. Further, as the downward rotation of the connector unit 12 progresses, the arm portion 68a is displaced downward while sliding in contact with the third protrusion 29, and the tip portion 68b of the arm portion 68a is displaced toward the side plate portion 38 side. The arm portion 68a is elastically deformed. Further downward rotation of the connector unit 12 causes the upper surface of the third protrusion 29 to come into contact with the side edge 49 of the connector unit 12, while the tip 68b of the arm portion 68a is elastically attached to the third protrusion 29. When engaged, the connector unit 12 is held in the retracted position (see FIGS. 11 and 13 (A) and the like).

As shown in FIG. 11, when the connector unit 12 is in the retracted posture, the engaging protrusion 57 of the lock arm 32 provided on the frame 9 fits into the second engaging recess 46c of the holding portion 54. It contributes to maintaining the posture of the connector unit 12 in the retracted posture and suppresses rattling of the connector unit 12.

Further, when the posture of the connector unit 12 is changed from the retracted posture to the used posture, when the user inserts a finger into the space 13 and rotates the connector unit 12 upward while hooking the fingertip on the fingernail portion 12c, the connector unit 12 is locked. The tip portion 68b is displaced upward against the elasticity of the arm portion 68a of the claw 68 to get over the tip portion of the third protrusion 29, and the arm portion 68a of the locking claw 68 is in sliding contact with the third protrusion 29. It passes by the side of the third protrusion 29, and then the upper end of the rib-shaped inclined portion 64 reaches the side of the third protrusion 29. Further, as the upward rotation of the connector unit 12 progresses, the main body 63 is displaced upward while the inclined portion 64 is in sliding contact with the third protrusion 29, and the engaging recess 62 is displaced toward the side plate 38 side. Elastically deforms. Further, as the upward rotation of the connector unit 12 progresses, the engaging recess 62 elastically engages with the third protrusion 29, and the connector unit 12 is held in the used posture (FIGS. 12 and 13 (B), etc.). reference).

Further, when the connector unit 12 is changed from the used posture to the retracted posture, when the connector unit 12 is rotated upward, the engaging recess 62 has a third protrusion against the elasticity of the main body 63 of the lock piece 61. The lower end inclined surface portion 69 is displaced upward from the portion 29, passes by the side of the third protrusion 29 while sliding in contact with the third protrusion 29, and the lock piece 61 is separated from the third protrusion 29. Further, the upward rotation of the connector unit 12 progresses, and when the unit top surface 12b of the connector unit 12 is in a retracted posture in which the unit top surface 12b stands up substantially vertically, the engaging protrusion 57 of the lock arm 32 provided on the frame body 9 holds the connector unit 12. The connector unit 12 is held in the retracted posture by fitting into the first engaging recess 46b of the portion 54 (see FIG. 10 and the like).

Next, the opening / closing cover 11 will be described. As shown in FIGS. 2, 7 and 8, the opening / closing cover 11 has a flat substrate that closes the wiring opening 6, and front and rear outer plates 51 and left and right side plates 52 provided on the lower surface thereof. It has a tray-like shape. As described above, the peripheral ribs integrally molded and erected upward are formed on the peripheral edge of the top surface portion of the substrate of the opening / closing cover 11, and the thin plate-shaped decorative plate 59 (adhered to the upper surface of the top surface portion inside the peripheral edge ribs) ( (See FIGS. 2 and 3) are provided.

Inside the opening / closing cover 11, two left-right and horizontally long partition plates 53 are provided in the front-rear direction. Therefore, the inside of the opening / closing cover 11 is divided into a plurality of grooves. The opening / closing cover 11 can be used as an accessory case by removing it from the frame body 9 and placing it on a desk in an upward opening posture. In that case, a thin device such as a smartphone can be leaned against the groove.

The left and right side side plates 52 of the opening / closing cover 11 are displaced inward to the left and right by a certain dimension (about the same as the protruding dimension of the bearing boss body 31) from the edge of the substrate. Then, as shown in FIGS. 8 and 9, side view substantially U-shaped holding portions 54 surrounding the bearing boss body 31 are integrally formed on the left and right side portions of the lower surface of the substrate. The holding portion 54 opens in the direction of one longitudinal side edge of the opening / closing cover 11.

The holding portion 54 of the opening / closing cover 11 has the same shape as the holding portion 46 of the connector unit 12. That is, the lower surface portion and the portion rising rearward of the outer peripheral surface of the holding portion 54 are formed as an arc-shaped outer peripheral surface 54a, and the first portion of the arc-shaped outer peripheral surface 54a is on the side of the opening end of the holding portion 54. An engaging recess 54b is formed, and a second engaging recess 54c is formed at an end of the arcuate outer peripheral surface 54a opposite to the open end of the holding portion 54. Further, a pair of upper and lower engaging protrusions 54e are provided on the inner peripheral surface of the holding portion 54. The holding portion 54 of the opening / closing cover 11 is not provided with a recess corresponding to the third engaging recess 46d provided in the holding portion 46 of the connector unit 12.

The opening / closing cover 11 can be attached to the bearing boss body 31 of the frame body 9 in the same manner as the attachment operation of the connector unit 12. That is, the holding portion 54 is aligned with the bearing boss body 31 with the opening / closing cover 11 raised (see FIG. 9), and the holding portion 54 is pushed toward the bearing boss body 31 to push the bearing portion 54 toward the bearing boss body 31. The holding portion 54 can be fitted into the bearing boss body 31 against the elasticity of 31 (see FIG. 10).

When the holding portion 54 of the opening / closing cover 11 is fitted into the bearing boss body 31 and then the opening / closing cover 11 is rotated downward to be in a horizontal posture, the engaging protrusion 57 of the lock arm 32 and the second engaging portion 54 are engaged. The opening / closing cover 11 is held in a horizontal posture by fitting the joint recess 46c. Therefore, even if the table vibrates, there is no rattling noise. The left and right side edges of the opening / closing cover 11 are mounted on the second protrusion 28 and the third protrusion 29 of the frame body 9. Therefore, the second protrusion 28 and the third protrusion 29 also have a function of holding the opening / closing cover 11 in the horizontal posture.

When the open / close cover 11 is touched with a fingertip and pushed upward (or pulled) against the elasticity of the lock arm 32, the open / close cover 11 can be raised. Fitted in the first engaging recess 46b, the open / close cover 11 is held in a substantially vertical position.

Since the opening / closing cover 11 can be held in the raised position, for example, when the hand is inserted into the wiring opening 6 for work, the opening / closing cover 11 is removed one by one, or the opening / closing cover 11 is held in the raised state with one hand. You don't have to be there. Therefore, the work can be performed quickly. When the opening / closing cover 11 is rotated against the elasticity of the lock arm 32, the holding portion 54 is elastically pushed by the lock arm 32, so that the opening / closing cover 11 can be opened arbitrarily by using friction. It is also possible to hold it in a posture. When one or a plurality of engaging recesses are formed between the first engaging recess 46b and the second engaging recess 46c, the opening / closing cover 11 is opened in an intermediate state between the fully open posture and the fully closed posture. Can be held firmly.

The frame body 9 can be an aluminum die-cast product as described above, or can be manufactured from an inexpensive general-purpose resin such as polypropylene. On the other hand, the bearing member 14 is preferably manufactured of a resin having excellent strength and durability, such as a polycarbonate resin or a nylon resin. The frame body 9 is made of aluminum to emphasize the metallic color, and the bearing member 14 is made of resin to secure the posture holding function of the opening / closing cover 11.

Further, as shown in FIG. 14, the frame body 9 may be a loop-shaped integrated product to which one connector unit 12 or an opening / closing cover 11 can be attached.

As described above, in the furniture with a top plate of the above embodiment, a square or U-shaped frame 9 extending along the inner circumference of the square wiring opening 6 provided in the top plate 1 is attached and connected. A square connector unit 12 having a terminal connection portion such as a port 42 provided on one side surface 12a of the unit is rotatably provided on the frame body 9 around an axis parallel to one side surface 12a of the unit. The connector unit 12 has a storage posture in which the unit top surface 12b is substantially horizontal and the terminal connection portion such as the connection port 42 is located below the top surface of the top plate 1, and the unit top surface 12b is on the top plate 1. On the other hand, in an inclined state, a terminal connection portion such as a connection port 42 is provided so that the posture can be changed from the usage posture located above the top plate 1. The connector unit 12 is provided with a posture holding mechanism 60 that engages and holds the connector unit 12 in the working posture.

In the above embodiment, since the posture holding mechanism 60 engages and holds the connector unit 12 in the used posture, the connector unit is held in the used posture by the urging force of the torsion coil spring. Sticking can be prevented, and the connector unit 12 can be reliably held in the usage posture. Then, when the power plug or the like is inserted into or removed from the connector unit 12 in the usage posture, the glare of the connector unit 12 can be suppressed, so that the user's usability is improved.

Further, as shown in FIG. 11 and the like, when the connector unit 12 is in the retracted posture, a space 13 is formed between the one side surface 12a of the unit and the frame body 9. As a result, the space 13 can be used as a wiring space through which wiring or the like is passed. For example, by putting the connector unit 12 in the retracted position with the power plug or the like inserted into the terminal connection portion such as the connection port 42 provided on the one side surface 12a of the connector unit 12, the top surface 12b of the unit can be raised. The height is substantially the same as the upper surface of the plate 1, and the top plate 1 can be used in a flat state, improving convenience.

As shown in FIG. 11 and the like, the space 13 is provided so that the user can insert a finger from above, and a finger hook portion 12c on which the user can hook the fingertip is provided on one side surface 12a of the connector unit 12. It is provided. As a result, the user puts a finger in the space 13 between the one side surface 12a of the unit and the frame 9 with respect to the connector unit 12 in the retracted posture, and hooks the finger on the finger hook portion 12c of the connector unit 12. However, the connector unit 12 can be easily raised, and the convenience is improved.

As shown in FIG. 10 and the like, in the connector unit 12, the top surface 12b of the unit stands upright from the tilted state in the usage posture and is substantially perpendicular to the top plate 1, and the terminal connection portion such as the connection port 42 is on the top. The posture can be changed to the retracted posture located above the plate 1. By setting the connector unit 12 in the retracted posture in this way, a large space can be formed between the connector unit 12 and the frame body 9, and the user can form a large space from above the top plate 1 through the space. The space under the top plate 1 (for example, the wiring duct 7 provided below the wiring opening 6) can be easily accessed.

By the way, in the furniture with a top plate disclosed in Patent Document 2, a torsion coil spring and a push latch mechanism are required to maintain the posture of the connector unit, and further, the torsion coil spring and the push latch mechanism are accommodated and the connector is provided. A bottomed box-shaped housing that rotatably supports the unit is required, and it has a complicated structure.

In the furniture with a top plate of the above embodiment, the connector unit 12 is rotatably supported by the frame body 9 provided along the inner circumference of the wiring opening 6, and the connector unit 12 itself is the posture holding mechanism 60. Since most of them are provided, the posture of the connector unit 12 can be changed between a working posture and a retracting posture with a simple configuration.

As shown in FIG. 13 and the like, in the posture holding mechanism 60, the engaging recesses 62 of the elastically deformable lock pieces 61 provided on the left and right side surfaces of the unit intersecting the unit one side surface 12a of the connector unit 12 are formed on the frame body 9. The connector unit 12 is held in the working posture by fitting to the third protrusion 29 (an example of the frame protrusion) projecting from the inner side surface. According to such a configuration, the posture holding mechanism 60 can be formed with a simple structure, the size of the entire connector unit 12 including the posture holding mechanism 60 can be made compact, and the posture holding mechanism 60 can be formed at low cost. ..

As shown in FIGS. 6 and 13, in the lock piece 61, the engaging recess 62 fits into the third protrusion 29 when the connector unit 12 is rotated upward from the retracted posture to the used posture. An inclined portion 64 is provided which is in sliding contact with the third protrusion 29 and displaces the engaging recess 62 in a direction away from the inner peripheral surface of the frame body 9 against the elastic force of the lock piece 61. As a result, when the connector unit 12 is raised from the retracted posture to the used posture, the engaging recess 62 of the lock piece 61 is automatically displaced in the direction away from the inner peripheral surface of the frame, and then the third protrusion. Since it is fitted to 29, the posture of the connector unit 12 can be changed from the retracted posture to the used posture with a simple operation. Further, since the operating load is increased before the connector unit 12 reaches the working posture, it is possible to suppress the operation of rotating the connector unit 12 too much, and the operability is improved.

As shown in FIGS. 6 and 13, the posture holding mechanism 60 is located below the third protrusion 29 when the connector unit 12 is in the retracted posture to regulate the upward rotation of the connector unit 12. Locking claws 68 are provided on the left and right side surfaces of the unit. The locking claw 68 is located directly below the third protrusion 29 when at least a part of the tip end portion 68b of the elastically deformable arm portion 68a extending diagonally upward from the base end portion toward the frame body 9 side is in the retracted posture. When the connector unit 12 is rotated downward from the used posture to the retracted posture, the middle portion of the arm portion 68a is set before the connector unit 12 is in the retracted posture. The tip portion 68b of the arm portion 68a is displaced in a direction away from the inner peripheral surface of the frame body 9 against the elastic force of the arm portion 68a by sliding contact with the three protrusions 29. As a result, when the connector unit 12 is pushed from the used posture to the retracted posture and closed, the closing operation load increases before the connector unit 12 reaches the retracted posture, so that the connector unit 12 suddenly closes. It is possible to suppress the closing and generation of a loud sound (impact). Further, when the connector unit 12 reaches the retracted posture, at least a part of the tip portion 68b of the arm portion 68a displaced from the tip portion of the third protrusion 29 to a position away from the inner peripheral surface is the arm portion. With the elastic force of 68a, it moves directly below the third protrusion 29 (a position closer to the inner peripheral surface than the tip of the third protrusion 29). As a result, the user who closes the connector unit 12 can feel that the connector unit 12 is closed (a signal that the connector unit 12 has reached the retracted posture) by sound or touch, and the usability is improved.

As shown in FIGS. 9 and 10, the connector unit 12 is provided by an elastic engaging means composed of a holding portion 46 provided on the connector unit 12 and a bearing boss body 31 provided on the frame body 9. It is detachably provided with respect to the frame body 9. As a result, the wiring opening 6 can be opened large by removing the connector unit 12, so that the space under the top plate 1 (for example, the wiring duct 7 provided below the wiring opening 6) can be easily accessed. .. Further, the member to be attached to the frame body 9 can be selected according to the user's request and purpose of use, such as being able to attach the opening / closing cover 11 having the same elastic engaging means as the connector unit 12, and the usability is improved. improves.

Further, as shown in FIGS. 2, 4 and 13, the furniture with a top plate of the above embodiment has a lid member (a lid member) that closes at least a part of the wiring opening 6 to the wiring opening 6 provided in the top plate 1. The center cover 10, the opening / closing cover 11 or the connector unit 12) are attached. For example, the connector unit 12 (an example of a lid member) has a peripheral rib 40 integrally molded and erected upward on the peripheral edge of the top surface portion 37, and a thin plate bonded to the upper surface of the top surface portion 37 inside the peripheral edge rib 40. It is provided with a decorative plate 50 having a shape.

As described above, the lid member (connector unit 12, center cover 10 or opening / closing cover 11) that closes at least a part of the wiring opening 6 includes a decorative plate 50, 58 or 59 bonded to the upper surface of the top surface portion thereof. Therefore, for example, the decorative plate 50, 58 or 59 is formed of a decorative plate 50, 58 or 59 having a design surface similar to that of the decorative plate 1a for the top plate attached to the decorative surface (upper surface) of the top plate 1. It is possible to create a sense of unity between the plate 1 and the lid member, and the appearance is improved. It is also possible to improve the design by forming the decorative plate 50, 58 or 59 of the lid member with a design surface different from that of the decorative plate 1a for the top plate. Further, since the decorative plate 50 is attached to the top surface portion 37 of the lid member (for example, the connector unit 12), even if a hole is formed in the top surface portion 37, the hole can be covered with the decorative plate 50. Since there is no effect on the appearance, the degree of freedom in designing the lid member is increased.

As shown in FIG. 13, the upper surface of the decorative plate 50 is arranged at the same height as the upper end of the peripheral rib 40, or is arranged on the upper surface side of the top surface 37 from the upper end of the peripheral rib 40. You may want to be there. As a result, an article (for example, a notebook computer, a writing tool, etc.) placed on the user's hand or the top plate 1 is placed on the peripheral portion (upper surface corner portion) of the decorative plate 50 of the lid member (for example, the connector unit 12). It is possible to prevent contact with each other, prevent the user from injuring his / her hand, and prevent the peripheral edge of the decorative plate 50 from being damaged and making it look unattractive.

As shown in FIGS. 2, 4 and 13, an example of the lid member is a connector unit 12 provided with a terminal connection portion on one side surface 12a of the unit of the main body case 15 made of synthetic resin. The connector unit 12 has a storage posture in which the top surface portion 37 formed of the upper surface portion of the main body case 15 is substantially horizontal and the terminal connection portion such as the connection port 42 is located below the upper surface portion of the top plate 1 (see FIG. 11). ) And the usage posture (see FIG. 12) in which the top surface portion 37 is tilted and the terminal connection portion is located above the top plate 1 so that the posture can be changed. As described above, even in the connector unit 12 having the main body case 15 made of synthetic resin, by providing the decorative plate 50 on the upper surface of the top surface portion 37 of the main body case 15, the design is the same as that of the top plate decorative plate 1a. The connector unit 12 having a surface can be formed to give a sense of unity between the top plate 1 and the connector unit 12, and the appearance is improved.

As shown in FIGS. 2 and 3, another example of the lid member is an opening / closing cover 11 made of synthetic resin, which is detachably provided on the frame body 9. As described above, even if the opening / closing cover 11 is made of synthetic resin, by providing the decorative plate 59 on the upper surface of the top surface portion, the opening / closing cover 11 having the same design surface as the decorative plate 1a for the top plate is formed. It is possible to create a sense of unity between the top plate 1 and the opening / closing cover 11, and the appearance is improved.

Although the embodiments of the present invention have been described above, the present invention can be embodied in various ways.
