Japanese Patent Laid-Open No. 2002-136345 (pages 2 and 3, FIG. 7)

  However, in the conventional resin cover, if the elastic piece is shortened, the amount of bending of the claw portion cannot be obtained, so the claw portion has to be made small, and a stable attachment state to the opening cannot be obtained. . On the other hand, if the elastic piece is lengthened to ensure the amount of bending of the claw, the thickness of the entire resin cover increases, and the mounting direction is limited to the direction from directly above the opening. There is also a problem that it is not possible to adopt an attachment method in which the side edge portion is used as a rotation axis and the other end portion is rotated and attached to the opening.

  As described above, the conventional resin cover leaves problems on both the ease of attachment and the attachment method, and this places a burden on the design.

  If it is such, even if it comprises the thickness dimension of a cover main body small, the extension dimension of an elastic piece can be enlarged. That is, a sufficient amount of displacement of the claw portion can be taken, so that it is easy to attach to the opening.

  Therefore, since the protruding amount of the claw part can be set large, a stable attachment state can be obtained, and it is possible to easily attach and provide a high value-added resin cover that does not impose a burden on the design. can do.

  Note that when the opening is closed by rotating the resin cover, the opening is not obstructed by the claw and the opening can be closed by a simple operation. In closing, it is desirable that the opening can be closed by rotating the other edge while supporting one edge on the furniture body. At this time, if the extending direction is a direction orthogonal to the attaching / detaching direction of the cover body, the effect becomes remarkable.

  In addition, if the elastic piece is a thin plate and the predetermined direction is the thickness direction of the elastic piece, a remarkable effect can be obtained.

  By the way, if the nail | claw part was provided in at least one edge part among the one edge part of the said cover main body, and the other edge part, it can be set as the workability | operativity good.

  The claw portion includes a first inclined surface that guides a closing operation to a predetermined portion of the furniture body when closing the opening, and temporarily closing the elastic piece when closing the opening. If it is configured so as to engage with a predetermined portion of the furniture body by utilizing the elastic deformation, the closing operation of the opening can be easily performed.

  In addition, the claw portion includes a second inclined surface that guides the opening operation to a predetermined portion of the furniture body when the opening portion is opened, and when the opening portion is opened, the elastic piece is temporarily mounted. If it is configured to be disengaged from the predetermined portion of the furniture body by utilizing the elastic deformation, the opening operation of the opening can be easily performed.

  Further, if the plurality of elastic pieces are arranged so that the respective claw portions provided on the tip end side thereof are close to each other, the resin cover can be more stably attached to the opening. Moreover, if the connecting piece which connects the distance between each nail | claw part variably is provided between these nail | claw parts, while being able to easily set the bending amount of a nail | claw part with a connecting piece, Can be linked.

  In order to ensure the strength of the base end portion of the elastic piece, the cover body includes a reinforcing rib for securing the strength of the cover body, and the base end portion of the elastic piece is It is desirable that the reinforcing rib be supported.

  If it is furniture provided with the resin cover comprised as mentioned above and the furniture main body provided with the opening part obstruct | occluded by the said resin cover, it shall be very easy to use the resin cover easily. be able to.

  As described above, according to the resin cover of the present invention, the cover main body for closing part or all of the opening of the furniture main body, and the cover main body for attaching the cover main body to the opening using elastic deformation. An elastic mounting portion, and the elastic mounting portion extends in an extending direction different from the attaching / detaching direction of the cover body, and is elastically deformable in a predetermined direction orthogonal to the extending direction and different from the attaching / detaching direction. The elastic piece and the claw part provided on the front end side of the elastic piece and attached to the furniture main body are provided. Therefore, even if the cover body has a small thickness, the elastic piece The extension dimension can be increased. That is, a sufficient amount of displacement of the claw portion can be taken, so that it is easy to attach to the opening.

  Therefore, since the protruding amount of the claw part can be set large, a stable attachment state can be obtained, and it is possible to easily attach and provide a high value-added resin cover that does not impose a burden on the design. can do.

  The auxiliary cover 2 includes a soft cover body 21 formed of a soft resin and a second engagement element 22 formed of a hard resin.

  And these soft cover bodies 21 and the 2nd engagement element 22 are formed by extrusion molding so that it may have cross-sectional shapes, such as each part, in a longitudinal direction.

  Each part will be described more specifically.

  The soft cover body 21 includes a soft cover upper element 211 and a soft cover lower element 212. Then, the base end side is fixedly supported by the second engagement element 22 and the respective distal end portions are made continuous so that the soft cover upper element 211, the soft cover lower element 212, the second engagement element. A hollow space 21x surrounded by 22 is formed.

  The soft cover upper element 211 has a substantially rectangular shape in plan view, and a base end portion thereof so that a base end portion side thereof and an upper piece 221 of a second engagement element 22 described later are superposed in plan view. The side is fixed from the upper piece 221 of the second engagement element 22 to the upper end portion of the upright piece 223. The upward surface 2110 is provided with a plurality of grooves 211a extending along the longitudinal direction.

  The soft cover lower element 212 has a substantially rectangular shape in plan view, and is fixed to the lower end side of an upright piece 223 of the second engagement element 22 described later. When the soft cover upper element 211 is viewed in plan, the soft cover upper element 211 and the soft cover lower element 212 are superposed, and the soft cover lower element 212 is visually recognized from above by the soft cover upper element 211. It is configured to be hidden by the impossible.

  On the other hand, the second engagement element 22 has a substantially U-shaped cross section, and includes a pair of an upper piece 221 and a lower piece 222, and an upright piece 223 that connects the upper piece 221 and the lower piece 222. Prepare.

  It should be noted that protruding pieces 22z are provided at the distal end portion of the upper piece 221 and the distal end portion of the lower piece 222, respectively, so that the dimension between the distal ends is smaller than the dimension between the proximal ends. Thus, the tip side sliding element 121y of the first engagement element 12 positioned in the second engagement element 22 is effectively prevented from coming into contact with the protruding piece 22z and being disengaged. ing.

  About the duct cover A comprised as mentioned above, the usage method is demonstrated below.

  (1) A method of attaching the duct cover main body 1 and the auxiliary cover 2.

  First, when the duct cover main body 1 and the auxiliary cover 2 are in a separated state, the first engagement element 12 of the duct cover main body 1 and the second engagement element 22 of the auxiliary cover 2 are positioned at close positions.

  When the operation of inserting the first engagement element 12 into the second engagement element 22 is performed, the tip of the sliding element 121 constituting the first engagement element 12 is tapered. One engagement element 12 can be easily inserted into the second engagement element 22.

  When a force is further applied in the direction in which the first engagement element 12 is inserted into the second engagement element 22, the first engagement element 12 is guided by the second engagement element 22 to start sliding. Since the distal end side sliding element 121y of the first engaging element 12 positioned in the second engaging element 22 is in contact with the protruding piece 22z and is prevented from being disengaged, The first engagement element 12 and the second engagement element 22 do not fall off, which is convenient.

  In the present embodiment, the first engagement element 12 is constituted by a plurality of sliding elements 121. However, both ends of each sliding element 121 are tapered, and the sliding elements 121 are straightened. Since they are arranged side by side on the line, there is no problem that the sliding element 121 and the second engagement element 22 abut on the way. In addition, the duct cover body 11 is formed by injection molding of a hard resin, but since the recess 121b1 is provided at a position corresponding to a so-called pouring gate into which the hard resin is charged at the time of molding, some burrs and the like due to molding remain. Even if it is, it does not contact | abut on the 2nd engagement element 22, and does not prevent sliding. That is, both ends of the duct cover body 1 and the auxiliary cover 2 can be positioned at a predetermined position where both ends of the duct cover body 1 and both ends of the auxiliary cover 2 are aligned by smooth sliding movement.

  In the above operation, if the second engagement element 22 of the auxiliary cover 2 is gripped so as to be sandwiched from above and below, the second engagement element 22 is formed of a hard resin, so that it does not bend by gripping. Since it can be gripped firmly, the feeling of operation and grip is good. Even if only the soft cover body 21 portion of the auxiliary cover 2 is gripped, the operational feeling and the grip feeling are improved as compared with the case where the entire auxiliary cover 2 is made of a soft resin.

  When the duct cover main body 1 and the auxiliary cover 2 are removed, if an external force is applied in a direction in which they are slid, the duct cover main body 1 and the auxiliary cover 2 can be easily slid to a disengageable position to be disengaged. Thus, since the duct cover main body 1 and the auxiliary cover 2 can be easily removed, for example, even when the soft cover body 21 needs to be replaced, this can be handled flexibly.

  (2) A method of attaching the duct cover A to the opening D4X1.

  As an example, first, the duct cover A is brought into a state where both ends of the duct cover main body 1 and both ends of the auxiliary cover 2 are aligned as described in (1). Then, as shown in FIG. 7 (S1), the downward inclined surface 116b1 of the counter-use end claw portion 116b is brought into contact with the distal end portion of the rear first mounting element D421 of the rear duct element D42.

  Next, the duct cover A is rotated in the direction of closing the opening D4X1 with the contact portion as the rotation center. When the duct cover A is rotated in this way, the claw portion 116b on the use end side is positioned at a position in contact with the front end portion of the front second mounting element D412 of the front duct element D41, and the duct cover A The upward surface 111a is in a horizontal state (see FIG. 7 (S2)).

  Further, when an external force is applied in the direction DR1 shown in FIG. 7, the downward inclined surface 116b1 of the claw portion 116b is formed at the tip of the rear first mounting element D421 and the tip of the front second mounting element D412, respectively. The connecting piece 116c is elastically deformed by being pressed.

  When an external force is further applied to the duct cover A in the direction DR1, the duct cover A is positioned at a position where the opening D4X1 is closed as shown in FIG. 7 (S3).

  In this closed state, on the use end side, the downward surface 111b of the top wall 111 and the front first mounting element D411 (or the downward surface of the end wall step 1133 and the front second mounting element D412) are contacted. On the other hand, the upward inclined surface 116b2 of the claw portion 116b and the front end portion of the front drop-off preventing element D413 come into contact with each other. In addition, the lower surface 115b2 of the support portion top piece 115b and the first rear mounting portion are disposed on the opposite end side. While the element D421 abuts, the upward inclined surface 116b2 of the claw part 116b abuts the tip of the rear drop-off preventing element D422, and the duct cover A is indirectly connected by elastic deformation of the connecting piece 116c that supports the claw part 116b. Therefore, the duct cover A that closes the opening D4X1 does not rattle unnecessarily in the vertical direction.

  The downward inclined surface 116b1 of the claw portion 116b on the counter-use end side is brought into contact with the front end portion of the rear first mounting element D421 of the rear duct element D42, and the use end side is rotated. The duct cover A is attached, but the downward inclined surface 116b1 of the claw portion 116b on the use end side is brought into contact with the front end portion of the front first mounting element D411 of the front duct element D41, so You may make it attach by rotating a use end side.

  Accordingly, the upward surface 111a of the hard cover body 11 and the upward surface 2110 of the soft cover body 21 are substantially flush with each other.

  (3) A method of attaching a plurality of duct covers A to the opening D4X1.

  By the way, when the plurality of duct covers A are attached to the opening D4X1, the protruding portion 113TX of the abutting portion 113T protruding from one end surface 1131 of the duct cover A positioned on the end side of the opening D4X1 becomes the corner portion D5. The projecting portion 113TX of the abutting portion 113T that abuts against the inner wall (not shown) and projects from the other end surface 1131 is in contact with the projecting portion 113TX of the abutting portion 113T that projects from the end surface 1131 of the adjacent duct cover A. (See FIG. 3).

  Further, the protruding portions 113TX of the contact portions 113T protruding from both end surfaces 1131 of the duct cover A positioned on the center portion side of the opening D4X1 are respectively the contact portions 113T protruding from the end surfaces 1131 of the adjacent duct covers A. It abuts on the protrusion 113TX (see FIG. 3).

  That is, the protrusion 113TX of the contact portion 113T provided in the duct cover A attached to the opening D4X1 contacts the protrusion 113TX of the contact portion 113T of the other duct cover A or the inner wall of the corner portion D5, respectively. The abutting portion 113T always receives an external force directed inward of each duct cover A.

  Therefore, the contact portion 113T that has received the external force is elastically deformed while being in contact with another contact portion 113T and the like, and retracts inward of the duct cover A.

  In this way, the gap SS1 between the end faces 1131 of the duct cover A is formed substantially uniformly, and the end faces 1131 and the corner portions of the end walls 113 constituting the duct covers A attached to both ends of the opening D4X1. Since the gap SS2 with the inner wall of D5 is also substantially uniform, the appearance as furniture can be improved (see FIG. 1).

  (4) A method of removing the duct cover A attached to the opening D4X1.

  First, the opposite end of the auxiliary cover 2 is turned upward so that a finger or the like can be inserted into the space formed when the auxiliary cover 2 is turned.

  Then, a finger or the like is put into the space where the auxiliary cover 2 is turned, the finger is put on the lower surface side of the auxiliary cover 2 and the like is lifted.

  Then, the counter-use end side starts to be lifted with the use end side as the center of rotation.

  Furthermore, if it rotates, engagement with the nail | claw part 116b and the rear side drop-off prevention element D422 will be cancelled | released, and the restrictions by the side of the non-use end of the duct cover A will be cancelled | released.

  At this time, the upward inclined surface 116b2 of the claw portion 116b that is in contact with the rear dropout prevention element D422 effectively guides the disengagement, so that the disengagement can be easily performed.

  Thus, the duct cover A can be removed from the opening D4X1.

  As described above, the duct cover A according to the present embodiment is elastic in the extending direction J2, which is a direction orthogonal to the attaching / detaching direction J1 of the duct cover body 1, even if the dimension of the attaching / detaching direction of the claw portion 116b is made small. If the piece 116a is extended, a sufficient amount of displacement of the claw portion 116b can be obtained, so that the ease of attachment to the opening D4X1 is not impaired.

  That is, it is possible to realize a duct cover A having a high added value that does not increase the size of the claw portion 116b, can be easily attached, and does not impose a burden on the design.

  Further, when the opening D4X1 is closed, the opening D4X1 can be closed by rotating the other edge while supporting one edge on the desk body DD. When the opening D4X1 is closed by rotating A, the rotation operation is not hindered by the claw portion 116b, and the opening D4X1 can be closed by a simple operation.

  Further, since the elastic piece 116a has a thin plate shape, it is easy to bend in the thickness direction.

  Moreover, since the nail | claw part 116b is provided in both the use end side and non-use end side of the duct cover main body 1, workability | operativity can be improved.

  Further, when the claw portion 116b closes the opening D4X1, the claw portion 116b includes a downward inclined surface 116b1 that guides the closing operation to the front duct element D41 and the rear duct element D2 of the desk body DD. When closing D4X1, the elastic piece 116a is configured to be engaged with the front duct element D41 and the rear duct element D2 of the desk body DD by using the temporary elastic deformation of the elastic piece 116a. The part D4X1 can be easily closed.

  In addition, the claw portion 116b includes an upward inclined surface 116b2 that guides the opening operation to the front duct element D41 and the rear duct element D2 of the desk body DD when the opening D4X1 is opened. When the portion D4X1 is opened, it is configured to be disengaged from the front duct element D41 and the rear duct element D2 of the desk body DD by using temporary elastic deformation of the elastic piece 116a. Therefore, the opening operation of the opening D4X1 can be easily performed.

  Further, since the plurality of elastic pieces 116a are arranged so that the respective claw portions 116b provided on the tip side thereof are close to each other, the duct cover A can be more stably attached to the opening D4X1. Further, since the connecting pieces 116a for connecting the distances between the claw portions 116b variably are provided between the claw portions 116b, the bending amount of the claw portions 116b can be easily set by the connecting pieces 116a. The part 116b can be interlocked.

  Further, the duct cover main body 1 includes the reinforcing rib 114 for securing the strength of the duct cover main body 1 and the base end portion of the elastic piece 116a is supported by the reinforcing rib 114. The strength of the proximal end portion 116a can be ensured.
