Description

The present invention relates to a shielding member, a fixture, and a plate body.

2. Description of the Related Art Hitherto, a shielding member has been known that shields the inner peripheral surface of an opening formed in a top plate of a desk or the like so as to penetrate in the thickness direction of the top plate (for example, see Patent Document 1). The shielding member is designed to solve problems related to operability and appearance when the top plate is made of wood and the structure of the wood is exposed on the inner peripheral surface of the opening. It is set in.

The shielding member described in Patent Document 1 is divided into two members from the viewpoint of ease of assembly. If the shielding member is not divided, there is a possibility that the combination position of the opening and the shielding member will not match due to processing accuracy of the opening of the top plate or dimensional error of the shielding member. In other words, if there is an error in dimensional accuracy, if the shielding member has a closed shape all around, it may not be possible to fit the shielding member in the specified position to the opening, or the inner peripheral surface of the opening may There is a possibility that a gap may occur between the shielding member and the shielding member, and the above problem is solved by dividing the shielding member into two as in Patent Document 1.

Patent No. 6881947

However, when the shielding member is divided into two parts, the abutting surfaces at the ends of the individual members constituting the shielding member may be misaligned with each other, which may deteriorate the appearance. There was room for improvement.

Therefore, the present invention has been made in view of the above circumstances, and provides a shielding member, a fixture, and a plate that can be installed on a top plate with a better appearance in a shielding member that shields the inner peripheral surface of an opening. provide.

In order to achieve the above object, the present invention employs the following means.
That is, the shielding member according to the present invention is a shielding member that shields the inner circumferential surface of an opening that penetrates through the thickness direction of a plate material, and includes a pair of shielding members that are divided into two parts having the same shape when the opening is viewed from above. A half-split frame member is provided, and an end portion of one half-split frame member of the pair of half-split frame members facing the other half-split frame member is provided with a groove facing toward an end of the other half-split frame member. an engagement convex portion that protrudes from the other half frame member; an engagement recess that engages with the engagement convex portion is formed at an end of the other half frame member; and the pair of half frame members It is characterized in that relative movement in at least one of the thickness direction and the inward direction of the opening is regulated by engagement between the engagement protrusion and the engagement recess.

In the shielding member according to the present invention, the pair of half-frame members are engaged with each other in at least one of the thickness direction and the inward direction of the opening by the engagement between the engagement protrusion and the engagement recess at the opposing ends. Since the relative movement of the pair of half-frame members is restricted, it is possible to suppress mutual displacement of the pair of half-frame members. As a result, it is possible to provide the shielding member in the opening in a state where the shielding member does not shift in position, and it is possible to improve the external appearance of the inner circumferential surface of the opening that is shielded by the shielding member.

Further, in the shielding member according to the present invention, the opening is formed in a rectangular shape, and the pair of half frame members is arranged in one of two directions vertically and horizontally along the length direction of the inner peripheral surface of the opening. It may be characterized in that it is divided into two parts by parallel dividing lines and formed in a U-shape when viewed from above.

In the shielding member configured in this way, the engaging protrusion and the engaging recess are provided at the opposing ends of the U-shaped half frame members, and these ends become free ends. , the half frame member has a structure that is easy to bend. Therefore, the pair of half frame members can be easily engaged with each other. In particular, when the shielding member is closed all around, it can be assembled efficiently.

Further, the shielding member according to the present invention is provided with a flange portion that engages with a surface side edge of the opening from the surface side, at a surface side end portion of the half frame member located on the surface side of the plate material. , the engagement convex portion and the engagement recess are formed on the back side of the plate material from the flange portion, and the opposing flange portions of the pair of half-frame members are in contact with each other. good.

In the shielding member configured in this way, when the pair of half-frame members are assembled, the positions of the pair of half-frame members in the opposing direction are determined by bringing the flanges on opposing surfaces into contact with each other. be able to. Therefore, when viewed in plan from the front side, there is no gap in the shielding member whose entire circumference is closed by the pair of half-frame members, and a beautiful appearance can be obtained. Since the flanges of the pair of half-frame members are in contact with each other in opposite directions, the engaging recesses and engaging protrusions that are located on the back side of the flange parts are molded with strict dimensional accuracy. This is not necessary, and it is possible to prevent the ease of assembling the half-frame members from decreasing due to dimensional errors during molding.

Further, in the shielding member according to the present invention, an opposing edge of the engaging convex portion formed on the one half-frame member, which faces an end of the other half-frame member, It is preferable that the engagement concave portion formed in the frame member is spaced apart from an opposing edge facing the engagement convex portion.

In the shielding member configured in this way, the gap formed between the opposing edge of one half-frame member and the opposing edge of the other half-frame member is used to prevent the formation of each half-frame member during molding. The error can be adjusted and assembled. For example, even if a dimensional error occurs that increases in the direction in which the opposing edges approach each other, it is possible to prevent the opposing edges from coming into contact with each other by forming a gap between the opposing edges. Since the flange portions can be brought into contact with each other reliably, it is possible to prevent the facing edges from coming into contact with each other and causing an opening (gap) on the surface side of the shielding member, thereby preventing the appearance from deteriorating.

Further, a fixture according to the present invention is a fixture including the above-described shielding member, and is characterized by comprising the shielding member and a plate material having the opening portion that is shielded by the shielding member.

The fixture according to the present invention has the above-mentioned effect of being able to provide the shielding member in the opening without any displacement, and improving the external appearance of the inner peripheral surface of the opening that is shielded by the shielding member. can be provided.

Further, a plate according to the present invention is a plate including the above-described shielding member, and is characterized in that it includes the shielding member and a plate having the opening that is shielded by the shielding member. .

The plate body according to the present invention has the above-mentioned effect that the shielding member without displacement can be provided in the opening, and the appearance of the inner peripheral surface of the opening shielded by the shielding member can be improved. We can provide plates.

According to the shielding member, the fixture, and the plate body according to the present invention, the shielding member that shields the inner circumferential surface of the opening can be installed on the top plate with a better appearance.

The shielding member according to the present embodiment shown in FIG. 1 is a member for shielding the inner circumferential surface 11a of the circumferentially closed opening 11 formed in the top plate 10 (plate material) of the desk 1 (fixture, plate body). It is.
The desk 1 includes a top plate 10 and four legs 12 that extend downward from the four corners of the top plate 10 and are spaced apart from each other on a floor surface F.

Here, in this embodiment, the left-right direction in a state where the person is seated facing the desk 1 is referred to as the symbol Dh, and the direction orthogonal to the left-right direction Dh in a plan view seen from above is referred to as the front-back direction Df. In addition, in the front-rear direction Df of the desk 1, the chair side (not shown) facing the top plate 10 (diagonally to the left on the paper in FIG. 1) is referred to as the front, and the side opposite to the front in the front-rear direction Df is referred to as the rear. It is called the rear side. Further, in the left-right direction Dh and the front-back direction Df, the direction facing the center of the desk 1 is defined as the inside, and the opposite side is defined as the outside.
Note that the desk 1 of this embodiment has a square top plate 10 and can be used by sitting at any position on the four sides, but for convenience of explanation, as described above, the top plate 10 is square in shape. The front left side is defined as the front or front side.

The desk 1 has a square shape with the same length in the left-right direction Dh and the front-back direction Df when viewed from above. The top plate 10 is fixed to the upper ends of four legs 12. A rectangular (square) opening 11 that opens both upward and downward is formed in the center of the top plate 10 when viewed from above. The legs 12 are long and are fixed to the lower surface 10b at the four corners of the top plate 10 by fixing means such as fixing bolts (not shown).

The opening 11 is a wiring opening for pulling out the wiring below the top plate 10 onto the top plate 10. The opening 11 is formed to penetrate through the top plate 10 in the thickness direction and to be closed all around. The inner circumferential surface 11a located in the hole portion of the opening 11 constitutes a substantially vertical surface.

The top plate 10 is made of wood, but may also be made of steel. A shielding member 20 is attached to the opening 11 to cover the inner circumferential surface 11a from the inside. Further, as shown in FIGS. 2 and 3, a wiring function section 2 is provided in the opening 11 to which the shielding member 20 is attached.

The wiring function section 2 includes a wiring receiver 30, a lid member 40, and a lid receiver support member 50.

As shown in FIGS. 3 to 6, the wiring receiver 30 has a shallow tray shape and is attached to the lower surface 10b of the top plate 10 below the opening 11. As shown in FIGS. The wiring receiver 30 has a function as a wiring duct, and is provided below the top plate 10 to receive wiring from below. The wiring on the wiring receiver 30 can be connected above the top plate 10 through the opening 11.
The wiring receiver 30 includes a receiving plate 31 formed in a substantially square flat plate shape and a support wall 32 extending upward from the receiving plate 31.

The receiving plate 31 has a plate surface parallel to the top plate 10 and is arranged horizontally. A support wall 32 that is bent upward from the receiving plate 31 is connected to two opposing sides 31a, 31a of the outer peripheral edge of the receiving plate 31. Outer edge flanges 33 projecting upward are provided on the other two opposing sides 31b, 31b of the outer peripheral edge of the receiving plate 31. The wiring arranged on the upper surface 31c of the receiving plate 31 is prevented from falling from the upper surface 31c of the receiving plate 31 because the surrounding area is higher than the upper surface 31c of the receiving plate 31 due to the support wall 32 and the outer edge flange 33. ing.

Further, a circular openable portion 31e is formed at the center of the receiving plate 31 when viewed from above. The openable portion 31e can be separated depending on the intended use, and an opening hole 31f can be formed in the receiving plate 31 in a separated state.

A pair of opposing support walls 32 are provided at the same height. Each support wall 32 has a notch 32a that is open at the top at the left and right center. Both left and right sides of the support wall 32 extend upward in the shape of a pillar. Top plate fixing portions 34 for fixing the support wall 32 to the lower surface 10b of the top plate 10 are provided at four upper end portions of the support wall 32. The top plate fixing portion 34 forms a horizontal surface, contacts the lower surface 10b of the top plate 10 with its surface, and is fixed by screws (not shown) serving as fixing means.

As shown in FIGS. 4 to 7, the lid receiving support member 50 is provided at the four corners 11c (see FIG. 2) of the opening 11 on the lower surface 10b of the top plate 10. As shown in FIGS. Each lid receiving support member 50 is attached so as to protrude into the opening 11 in order to support the four corners of the lid member 40. The lid receiver support member 50 includes a substrate 51 whose outer end is substantially rectangular in plan view and which is fixed to the lower surface 10b of the top plate 10 by a plurality of screws (not shown), and a corner of the opening 11 on the upper surface of the substrate 51. The lid engaging portion 52 is located at 11c and protrudes to engage a corner portion of the lid member 40.

The portion of the substrate 51 where the lid engaging portion 52 is not disposed serves as a top plate fixing surface 51a. The top plate fixing surface 51a is in surface contact with the lower surface 10b of the top plate 10 and is fixed by a screw of a fixing means. A columnar support tube 53 is provided on the lower surface of the substrate 51 and is connected downward. Note that the support tube 53 may have a hollow cylindrical shape or may be solid. A plurality of reinforcing ribs 54 connected to the lower surface of the substrate 51 are provided on the outer peripheral surface of the support tube 53. The substrate 51 is supported from below by reinforcing ribs 54.

The lid engaging portion 52 engages the two outer edges of the lid member 40 while being placed from above. That is, the lid engaging portion 52 restricts horizontal movement and downward movement of the lid member 40, and arranges the lid member 40 so as to close the opening 11 of the top plate 10 from above. The lid engaging portion 52 has an upper engagement protrusion 55 that projects upward from the substrate 51 and a lower engagement protrusion 56 that is lower in height than the upper engagement protrusion 55 . The upper engaging convex portion 55 is disposed at a position facing a top portion 41c (see FIG. 5) of a cover body 41 (described later) of the lid member 40. The upper engagement protrusion 55 and the lower engagement protrusion 56 are arranged so as to sandwich the shielding member 20 between the corners 11c of the opening 11, as described above.

As shown in FIG. 5, the upper engagement protrusion 55 has a first locking side surface 55a and a second locking side surface 55b that are parallel to the two sides forming the corner of the lid member 40 and intersect with each other at right angles. . The lower engagement protrusion 56 extends perpendicularly from the first locking side surface 55a of the upper engagement protrusion 55 when viewed from above, and the second engagement side 55b extends from the second locking side surface 55b of the upper engagement protrusion 55. and one extending in the orthogonal direction.

An engagement recess 43a (described later) formed in a corner 41b of the cover body 41 of the lid member 40 engages with the upper engagement protrusion 55. At this time, each of the first locking side surface 55a and the second locking side surface 55b of the upper engagement convex portion 55 is in contact with or close to the inner circumferential surface of the engagement recess 43a.

A corner portion of the lid member 40 is placed on the upper surface 56a of the lower engagement convex portion 56 from above. A locking groove 56b is formed in the upper surface 56a of the lower engagement protrusion 56 and extends parallel to the direction in which each lower engagement protrusion 56 extends and opens upward. In this locking groove 56b, a protrusion 43c (see FIG. 6) of a corner member 43 of the lid member 40, which will be described later, is inserted into the locking groove 56b when the lid member 40 is engaged with the lid receiver support member 50 and closes the opening 11. It is locked.

As shown in FIGS. 5 to 7, the lid member 40 is removably attached to the opening 11 so as to maintain the closed state by having the four corners supported by the lid receiving support member 50. The lid member 40 includes a cover body 41 having a rectangular plate shape (square plate shape) whose thickness is smaller than the thickness of the top plate 10 and slightly smaller than the size of the opening 11, and corner portions at the four corners of the cover body 41. An edge cover 42 protrudes in the same direction from the outer circumferential surface 41a of each side except for 41b, and corner members arranged at each corner 41b of the four corners of the cover body 41 so as to extend on both sides of the edge cover 42. It is equipped with 43 and. The cover body 41 is made of resin, for example.

A base end portion of the edge cover 42 is fixed to the lower surface of the outer peripheral surface 41a of the cover body 41. The edge cover 42 is a flexible plate-like member made of, for example, rubber or elastomer. The outer shell portion formed by the outer edges 42a of the four edge covers 42 approaches the inner wall surface of the shielding member 20 provided in the opening 11 of the top plate 10 with almost no gap. That is, the edge cover 42 closes the gap between the outer circumferential surface 41 a of the cover body 41 and the inner wall surface of the shielding member 20 .

The corner member 43 is fixed to the lower surface of the cover body 41 by fixing means such as screws (not shown) so as to be substantially flush with the upper surface of the edge cover 42 . When the lid member 40 is attached to the opening 11 of the top plate 10 at a predetermined position, the corner member 43 is placed so as to overlap the upper surface 56a of the lower engaging protrusion 56 of the lid receiver support member 50. Ru.

The corner member 43 is formed with an engaging recess 43a that intersects at right angles when viewed from above by the corner members 43 adjacent to each other with the top 41c of the cover body 41 in between. The engagement recess 43 a engages with an upper engagement protrusion 55 provided on the lid receiver support member 50 . When the engagement recess 43a engages with the upper engagement protrusion 55, the orthogonal inner peripheral surfaces forming the engagement recess 43a become the first locking side surface 55a and the second locking side of the upper engagement protrusion 55, respectively. Since the cover member 40 is positioned opposite the side surface 55b, movement of the cover member 40 in two orthogonal directions along the outer circumferential surface 41a of the cover body 41 is restricted.

A protrusion 43c parallel to the outer circumferential surface 41a of the cover body 41 is provided on the lower surface of the tip of each corner member 43 to protrude downward. The protrusion 43c is locked from above in a locking groove 56b of a lower engaging convex portion 56 provided on the lid receiver support member 50.

Here, a method for attaching the lid member 40 to the opening 11 will be explained. Specifically, the lid member 40 is attached to the shielding member 20 fixed to the inner peripheral surface 11a of the opening 11. At this time, the wiring receiver 30 and the lid receiver support member 50 are fixed to the lower surface 10b of the top plate 10. Further, a shielding member 20, which will be described later, is also fixed to the inner circumferential surface 11a of the opening 11.

When attaching the cover member 40 to the opening 11, the cover member 40 is inserted into the opening 11 from above, and the corner members 43 attached to the four corners 41b of the cover body 41 are attached to the top of the cover body 41. The engagement recesses 43a formed by the corner members 43 adjacent to each other with 41c in between are engaged with the upper engagement protrusions 55, and the lower engagement recesses 43a formed on the lid receiver support member 50 attached to the corner 11c of the opening 11 are connected to each other. It is placed on the upper surface 56a of the engagement convex portion 56. Thereby, the lid member 40 is attached to the opening 11.

In this state, by elastically deforming the edge cover 42 of the lid member 40, the cables of OA equipment etc. placed on the top plate 10 can be dropped into the receiving plate 31 of the wiring receiving plate 30 and wired. Further, when placing a large electrical device such as a desk tap on the wiring receiver 30 from above the top plate 10, the lid member 40 may be removed from the opening 11.

As shown in FIG. 3, FIG. 8, FIG. 9, and FIG. It is formed by occlusion. The shielding member 20 is formed by molding synthetic resin.

The shielding member 20 engages with the inner circumferential surface 11a of the opening 11 and a frame plate member 21 having a vertical surface facing the inner circumferential surface 11a of the opening 11, and the frame plate member 21 has a vertical surface facing the inner circumferential surface 11a of the opening 11. A driving needle 22 for the tacker 60 that holds the tacker 21 is provided (see FIGS. 11 and 12). The frame plate member 21 is a substantially square thin plate-like frame with rounded corners. As shown in FIGS. 11 and 12, the frame plate member 21 is fixed to the inner circumferential surface 11a of the opening 11 by a driving needle 22, and is supported on the top plate 10 while shielding the inner circumferential surface 11a.

The driving needle 22 is driven into the driving opening 61 of the tacker 60 in a direction substantially perpendicular (substantially horizontal) to the inner circumferential surface 11a of the opening 11 and is fixed to the top plate 10 by frictional force. The driving needle 22 is driven into the frame plate member 21 between the inner peripheral surface 11a and a friction engagement portion 221 that is driven in a direction intersecting the inner peripheral surface 11a of the opening 11 and is fixed to the top plate 10 by frictional force. A holding part 222 that holds the. The driving needle 22 is, for example, a U-shaped stable, but is not limited to such a needle shape, and may be an engagement member such as a nail.

As the tacker 60 used, a commonly known tacker can be adopted. As shown in FIG. 12, the tacker 60 includes a tacker main body 62 having a driving opening 61 at the tip of which the driving needle 22 is driven out, a handle 63 provided on the opposite side of the driving opening 61, and a handle 63 provided on the handle 63. This is a hand-held jig that is integrally provided with an operating section 64. With the tacker 60, there is no need for the driving direction to be perpendicular to the surface to be driven (in this case, the indicating wall portion 212b of the lower wall 212, which will be described later), and even an oblique position is almost equivalent to driving in a horizontal position. It can be driven into and engaged with the top plate 10 constituting the opening 11 quickly and reliably.

As shown in FIGS. 11 and 13, the frame plate member 21 includes an upper wall 211 of a thin portion located on the upper side, and a lower wall 212 of a thick portion located below the upper wall 211. The upper wall 211 is formed with an inclined surface 211a that gradually slopes toward the inner circumferential surface 11a of the opening 11 as the inner circumferential surface goes upward from below. The inner peripheral surface of the lower wall 212 forms a vertical surface 212a. That is, the upper wall 211 is thinner than the lower wall 212. Therefore, in the shielding member 20, the opening on the upper end 20a side is larger than the opening on the lower end 20b side. Specifically, the shielding member 20 maintains its shape while attached to the top plate 10. Therefore, when the shielding member 20 is attached to the top plate 10, the distance between the two opposing sides at the top of the shielding member 20 is larger than the distance between the two opposing sides at the bottom.
As shown in FIG. 12, the driving needle 22 is passed through the lower wall 212 in the thickness direction. The driving needle 22 that has penetrated the lower wall 212 is then engaged with the inner circumferential surface 11a of the opening 11.

On the vertical surface 212a of the lower wall 212, a plurality of indicator wall portions 212b for indicating the engagement position of the driving needle 22 are provided at regular intervals in the circumferential direction. In this embodiment, the indicator wall portions 212b are provided at five locations on one side of the frame plate member 21 (see FIG. 8). Among the five indicator wall parts 212b, the indicator wall part 212b located at the engagement part between the half frame members 23 and 24, which will be described later, is in a state where both of the pair of half frame members 23 and 24 overlap in the thickness direction. It is penetrated by the driving needle 22. As shown in FIG. 11, the indicator wall portion 212b has a height from the lower end to the vicinity of the upper end (lower end of the upper wall 211) in the vertical plane 212a of the lower wall 212, and a width that is greater than the length of the clamping portion 222 of the driving needle 22. It has large dimensions. The indicator wall portion 212b is a thin wall portion that is recessed from the vertical surface 212a of the lower wall 212 toward the inner circumferential surface 11a of the opening 11.

As shown in FIGS. 8 and 9, the frame plate member 21 of the shielding member 20 is arranged in one of the vertical and horizontal directions (the left-right direction Dh and the front-back direction Df) along the inner peripheral surface 11a of the opening 11 (here, A pair of half frame members 23 and 24 (first half frame member 23, A second half frame member 24) is provided. The first half-frame member 23 and the second half-frame member 24 have the same shape including the engaging portions formed at their respective ends 23a, 23b, 24a, and 24b.

As shown in FIGS. 8 to 11, the first end 23a of the first half frame member 23 facing the second half frame member 24 has a first end 24a of the second half frame member 24. An engagement convex portion 231 is formed that protrudes toward. The engaging protrusion 231 is formed at the lower part of the first end 23a. The second end 23b of the first half-frame member 23 is formed with an engagement recess 232 that engages with an engagement convex portion 241, which will be described later, formed on the second end 24b of the second half-frame member 24. has been done. The engagement recess 232 is formed at the lower part of the second end 24b.
An engagement recess 242 that engages with the engagement protrusion 231 of the first half frame member 23 is formed in the first end 24 a of the second half frame member 24 . The engagement recess 242 is formed at the lower part of the first end 24a. An engagement protrusion 241 that engages with the engagement recess 232 of the second end 23b of the first half frame member 23 is formed on the second end 24b of the second half frame member 24. The engaging protrusion 241 is formed at the lower part of the second end 24b.

As shown in FIG. 9, the engagement recess 232 of the first half frame member 23 and the engagement recess 242 of the second half frame member 24 have openings in the engagement protrusions 231 and 241 that are respectively engaged. Regulating plates 234 and 244 are provided to restrict movement to the inside of the portion 11. The regulating plates 234 and 244 are provided in the space inside the engagement recesses 232 and 242 so as to overlap from the inside of the opening 11 in the thickness direction of the frame plate member 21. That is, the regulation plates 234 and 244 overlap in the thickness direction with respect to the engagement protrusions 231 and 241 engaged with the engagement recesses 232 and 242. Since the regulating plates 234 and 244 overlap on the inside of the engagement convex portions 231 and 241 (inward of the opening 11), the pair of half-frame members 23 and 24 cannot move inward of the opening 11. It is possible to prevent misalignment due to

In this way, the pair of half-frame members 23 and 24 are arranged such that the respective engagement protrusions 231 and 241 are engaged with the engagement recesses 232 and 242, and the regulation plates 234 and 244 and the engagement protrusions 231 and 241 are engaged with each other. Relative movement in the vertical direction and inward of the opening 11 is restricted by contact with the opening 11 .

As shown in FIGS. 11 and 12, the upper ends 20a of the half-frame members 23 and 24 are provided with flanges 233 and 243 that engage with the upper edge 11b (front side edge) of the opening 11 from above. We are prepared. The flange portions 233 and 243 protrude from the upper end portions 20a of the half frame members 23 and 24 toward the opening 11 side in a side view seen from a direction perpendicular to the cross section of the frame plate member 21.

As shown in FIG. 14, the engaging protrusions 231, 241 and the engaging recesses 232, 242 are formed below the flange parts 233, 243. The opposing flanges 233 and 243 of the pair of half frame members 23 and 24 are in contact with each other.

Below the flanges 233 and 243, the first opposing edge 23c of the engagement convex portion 231 formed on the first half-frame member 23 faces the first end 24a of the second half-frame member 24. It is spaced apart from the second opposing edge 24c of the engagement recess 242 formed in the second half frame member 24, which faces the engagement convex portion 231 of the first half frame member 23. That is, when the pair of half frame members 23 and 24 are combined in a closed state, a slight gap S is formed between the first opposing edge 23c and the second opposing edge 24c. .

As shown in FIG. 15, when attaching the shielding member 20 to the opening 11 of the top plate 10, first, the frame plate members 21 are placed facing each other so as to shield the inner circumferential surface 11a of the opening 11. Specifically, one of the first half-frame members 23 is temporarily placed in a half area of the inner circumferential surface 11a of the opening 11 in advance. At this time, the driving needle 22 is not driven by the tacker 60 yet. Next, the second half-frame member 24 is placed on the inner circumferential surface 11a of the opening 11, and assembled with the preceding first half-frame member 23. At this time, the engaging protrusions 231 and 241 and the engaging recesses 232 and 242 of the first half frame member 23 and the second half frame member 24 are engaged with each other. Note that the second half frame member 24 may be placed in advance.

Next, as shown in FIG. 16, at least the driving opening 61 of the tacker 60 is entered into the inside surrounded by the frame plate member 21, and the driving needle 22 is driven by the tacker 60 toward the inner circumferential surface 11a of the opening 11. , the frame plate member 21 (a pair of half-split frame members 23 and 24) is fixed to the inner peripheral surface 11a with the driving needle 22, and the shielding member 20 is attached to the top plate 10 with the inner peripheral surface 11a shielded by the frame plate member 21. (See Figure 13). In this way, the shielding member 20 can be assembled so as to shield the inner circumferential surface 11a of the opening 11.

In this embodiment, the first half frame member 23 is placed in the opening 11 in advance, and then the second half frame member 24 is placed in the opening 11. Although the split frame member 23 and the second half frame member 24 are combined, the procedure is not limited to arranging them individually. That is, after combining the two first half-frame members 23 and the second half-frame members 24 in advance, the frame plate member 21 combined into a rectangular shape is assembled into the opening 11 and driven with the tacker 60. The needle 22 may be driven into the inner peripheral surface 11a of the opening 11.

In this embodiment, in the assembly method for attaching the shielding member 20 to the opening 11 of the top plate 10, the driving needle 22 is engaged by driving into the top plate 10 of the opening 11, that is, the driving needle 22 Since the frame plate member 21 is engaged with the inner circumferential surface 11a of the opening 11 by frictional force in the driving direction, a tool such as a driver for tightening a fastening member such as a screw must be coaxial with the screw shaft. Even if the opening 11 is closed all around, the tacker 60 can be placed in a horizontal position by entering at least the driving opening 61 of the tacker 60 into the opening 11. The driving needle 22 can also be driven into the top plate 10 of the opening 11 reliably and while maintaining a good appearance. Therefore, it is possible to reliably prevent the shielding member 20 from falling off from the opening 11.

The shielding member 20 configured in this manner shields the inner peripheral surface 11a of the opening 11 that penetrates the top plate 10 in the thickness direction. The shielding member 20 includes a pair of half-frame members 23 and 24 that are divided into two parts having the same shape when the opening 11 is viewed from above. An engagement protrusion 231 that protrudes toward the first end 24a of the second half frame member 24 is formed at the first end 23a facing the second half frame member 24. An engagement recess 242 that engages with the engagement protrusion 231 is formed at the first end 24 a of the second half frame member 24 . Relative movement of the pair of half-frame members 23 and 24 in at least one of the vertical direction and the inward direction of the opening 11 is restricted by engagement between the engagement protrusion 231 and the engagement recess 242. .

As described above, in the present embodiment, the pair of half-frame members 23 and 24 are connected in the vertical direction and in the opening by the engagement between the engagement protrusion 231 and the engagement recess 242 at the opposing ends 23a and 24a, respectively. Since the relative movement of the portion 11 in at least one of the inward directions is restricted, it is possible to suppress mutual displacement of the pair of half-frame members 23 and 24. Thereby, the shielding member 20 can be provided in the opening 11 without any displacement, and the appearance of the inner circumferential surface 11a of the opening 11 shielded by the shielding member 20 can be improved.

Further, in this embodiment, the opening 11 is formed in a rectangular shape. The pair of half-split frame members 23 and 24 are divided into two parts by a dividing straight line K that is parallel to one of two vertical and horizontal directions (left-right direction Dh and front-back direction Df) along the length direction of the inner circumferential surface 11a of the opening 11. It is formed into a U-shape when viewed from above.
Therefore, the engaging protrusions 231, 241 and the engaging recesses 232, 242 are provided at the opposing ends 23a, 23b, 24a, 24b of the U-shaped half frame members 23, 24. Since the portions 23a, 23b, 24a, and 24b are free ends, each half frame member 23, 24 has a structure that can be easily bent. Therefore, the pair of half frame members 23 and 24 can be easily engaged with each other. In particular, when the shielding member 20 is closed all around, it can be assembled efficiently.

In this embodiment, the ends of the half frame members 23 and 24 located on the upper surface 10a side of the top plate 10 are provided with flange portions 233 and 243 that engage with the upper edge 11b of the opening 11 from above. We are prepared. The engagement convex portion 231 and the engagement recess 242 are formed closer to the lower surface 10b of the top plate 10 than the flange portions 233, 243, and the opposing flange portions 233, 243 of the pair of half frame members 23, 24 are in contact with each other. ing.

With such a configuration, when the pair of half-frame members 23, 24 are combined, by bringing the opposing flanges 233, 243 into contact with each other, the opposing direction of the pair of half-frame members 23, 24 can be adjusted. can be positioned. Therefore, in a plan view from above, there is no gap in the shielding member 20 whose entire circumference is closed by the pair of half-split frame members 23 and 24, and a beautiful appearance can be obtained.
Since the flanges 233 and 243 of the pair of half-frame members 23 and 24 are in contact with each other in opposite directions, the engagement recess 242 and the engagement protrusion 231 arranged below the flanges 233 and 243 It is not necessary to mold with strict dimensional accuracy, and it is possible to prevent the ease of assembling the half frame members 23 and 24 from being deteriorated due to dimensional errors during molding.

Further, in the present embodiment, the opposing edge 23c of the engagement convex portion 231 formed on the first half frame member 23 facing the end of the second half frame member 24 is connected to the second half frame member 23. It is spaced apart from the opposing edge 24c of the engagement recess 242 formed in the engagement convex portion 231.

In this case, the gap S formed between the opposing edge 23c of the first half-frame member 23 and the opposing edge 24c of the second half-frame member 24 separates the respective half-frame members 23 and 24. It is possible to assemble by adjusting the errors during molding. For example, even if a dimensional error occurs that increases in the direction in which the opposing edges 23c, 24c approach each other, the gap S can be formed between the opposing edges 23c, 24c. can be prevented from coming into contact with the Since the flanges 233 and 243 can be brought into contact with each other reliably, the opposing edges 23c and 24c come into contact with each other, creating an opening (gap) at the upper end 20a of the shielding member 20, which deteriorates the appearance. can be prevented from happening.

Furthermore, since the desk 1 and the plate body having the top plate 10 according to the embodiment include the shielding member 20 and the top plate 10 having the opening 11 that is shielded by the shielding member 20, a state in which there is no positional shift is provided. The shielding member 20 can be provided in the opening 11, and it is possible to provide the above-mentioned effect of improving the external appearance of the inner circumferential surface 11a of the opening 11 that is shielded by the shielding member 20.

Note that the technical scope of the present invention is not limited to the embodiments described above, and various changes can be made without departing from the spirit of the present invention.

For example, in the embodiment shown above, the top plate 10 of the desk 1 is used as an example of the plate material on which the opening 11 is formed, but the plate material is not limited to the top plate 10. For example, the plate material may be a wall or partition whose surface direction is oriented in the vertical direction, and the shielding member may be fixed to an opening formed in such a vertical wall surface.

Further, in the present embodiment, the top plate 10 is approximately square in plan view, and the opening 11 is formed in the center of the top plate 10, which is approximately square (rectangular) in plan view. The planar shape and size of the opening 11, the position of the opening 11 with respect to the top plate 10, and other configurations can be changed as appropriate. For example, the opening may be circular in plan view. The opening is not limited to an opening that is closed all around as in this embodiment, but may also be applied to an opening that is partially open in the circumferential direction of the opening. It is possible.

Further, in this embodiment, the driving needle 22 driven by the tacker 60 is used as an engaging member that engages with the inner circumferential surface 11a of the opening 11 and clamps the frame plate member 21 between the inner circumferential surface 11a and the inner circumferential surface 11a. However, the engagement member is not limited to the driving needle 22. For example, it is also possible to employ a driving member such as a nail material. In short, the engaging member need only be a member that holds the frame plate member 21 between it and the inner circumferential surface 11a, rather than being tightened like a screw.

Further, in the embodiment, the frame plate member 21 includes an upper wall 211 of a thin wall portion and a lower wall 212 of a thick wall portion, and the driving needle 22 is passed through the lower wall 212 of the thick wall portion to open the opening 11. Although the structure is such that it engages with the inner circumferential surface 11a, the structure is not limited to such a structure in which the thickness of the upper part of the frame plate member 21 is made thin, and the overall thickness of the frame plate member 21 may be made constant. .

Furthermore, in this embodiment, the lower wall 212, which is a thick portion, is provided with an indicator wall 212b (indicator) that indicates the engagement position of the engagement member. It is also possible to omit it. Further, although the indicator wall portion 212b is shaped to be recessed from the inner surface of the lower wall 212 toward the inner circumferential surface 11a of the opening 11 as in the present embodiment, it is not limited to such a shape. For example, as another form of the indicator part, instead of the indicator wall part 212b recessed from the inner surface of the lower wall 212, the indicator wall part 212b may be recessed from the inner surface of the lower wall 212 in the circumferential direction of the engagement position of the engagement member on the flat inner surface (vertical surface 212a) of the lower wall 212. A pair of rib-shaped walls protruding in the inner circumferential direction of the opening 11 and extending in the vertical direction may be used as the indicating portions at the positions on both sides. In this case, the engagement position is between the pair of rib-shaped wall portions. Further, by using a rib-shaped wall portion as the indicator portion, there is an effect of increasing the rigidity of the shielding member at the portion where the engaging member is driven.
The number of indicator walls 212b provided on each side of the frame plate member 21 is not particularly limited, and the number of indicator walls 212b can be determined depending on the engagement location of the engagement member.

Furthermore, the configuration of the wiring function section 2 provided in the opening 11 is not limited to the above-described embodiment, and the wiring function section 2 may be omitted. Further, the wiring function section 2 that accommodates the wiring is not limited to being disposed in the opening 11, and a configuration in which a function section having another function is attached to the opening 11 may be adopted.

Further, in this embodiment, the upper end portions 20a of the half frame members 23 and 24 (frame plate member 21) are provided with flange portions 233 and 243 that engage with the upper edge portion 11b of the opening 11 from above. However, it is also possible to omit these flange portions 233, 243.

Further, in this embodiment, the opposing edge 23c of the first half frame member 23 is separated from the opposing edge 24c of the second half frame member 24, and a gap S is formed between the opposing edges 23c and 24c. However, it is also possible to have a configuration in which such a gap S is not formed.

Further, the respective engagement structures of the first half frame member 23 and the second half frame member 24 are not limited to the above embodiment. For example, the engagement recesses 232 and 242 of the first half-frame member 23 and the second half-frame member 24 are formed into engagement holes that are surrounded on the entire circumference by covering both sides in the thickness direction and both upper and lower sides of the frame plate member 21. The engaging protrusions 231 and 241 may be configured as engaging protrusions that engage with the engaging holes.

In addition, without departing from the spirit of the present invention, the components in the embodiments described above may be replaced with well-known components as appropriate, and the modifications described above may be combined as appropriate.
