Description

  The present invention relates to a cover positioning mechanism that is preferably used when a cover is attached to a joint existing on an end surface of a panel structure.

Panel structures include top plates and legs. In this type of panel structure, there may be joints on the end faces, and in order to conceal such joints together with the end faces by the cover, an insertion piece is provided on the cover by the same mounting structure as in Patent Document 1, Usually, the insertion piece is inserted into the joint at the end face to position the cover.
Japanese Utility Model Publication No. 6-40170

  However, there are processing and assembly errors in the panel structure and the like, and the joint width may vary. If the variation in joint width is allowed, the positional deviation of the cover becomes severe. If the variation in joint width is restricted, the cover becomes difficult to enter the joint. When the insertion piece also serves as a cover mounting function, the setting conditions for achieving both the ease of attaching and detaching the cover and the positioning function are more difficult. This leads to a stable mounting state.

  The present invention has been made paying attention to such a problem, and has a cover positioning mechanism that enhances its positioning function without impairing the ease of attaching and detaching the cover, and at the same time, can optimize the mounting state. It is intended to provide.

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

  That is, when the cover positioning mechanism according to the present invention attaches a cover to a position straddling a pair of adjacent members via a joint, the cover is formed on each member located on both sides of the joint, while the cover Provided with a first insertion piece to be inserted into the joint and a second insertion piece to be inserted into the window. When the cover is displaced in the width direction at the mounting position, processing between members, assembly error, etc. A mode in which the first insertion piece preferentially engages with the opening edge of the joint and a mode in which the second insertion piece preferentially engages with the opening edge of the window according to the fluctuation of the joint width caused by It is characterized in that it can be taken.

  With this configuration, the cover can be attached even if the joint width varies, and the positioning function can be ensured regardless of whether the joint is expanded or contracted. For this reason, it becomes possible to optimize the positioning function and to maintain good adhesion of the cover to the member while ensuring the ease of attaching and detaching the cover.

  In order to avoid an increase in the number of insertion points as much as possible, the first insertion piece or the second insertion piece also serves as a mounting piece for engaging the cover with the member so as not to fall off, or the mounting piece. It is desirable to provide them integrally.

  In order to ensure the ease of attaching and detaching the cover, it is preferable that the second insertion piece is provided at an intermittent position along the joint.

  For the same purpose, it is preferable that the first insertion piece is also provided at an intermittent position along the joint.

  As a suitable application target of the present invention, there is a member in which the member is a steel plate in which a bent piece is wrapped around the end surface, and a cover is attached to a position covering the end surface.

  This is particularly effective when the steel sheet is pressure-bonded to both side surfaces of a core material such as a paper honeycomb core to form a panel structure together with the core material.

  In order to achieve a proper mounting state of the cover while allowing tolerance, the first insertion piece can be closely inserted into the joint when the distance between the members is the narrowest within the tolerance range allowed in advance. Therefore, it is desirable to set the second insertion piece so that the second insertion piece can be closely inserted into the window when the space between the members spreads most.

  Since the present invention has the configuration described above, it is possible to enhance the positioning function without impairing the ease of attaching and detaching the cover, and it is possible to attach the cover while being in close contact with the member. It is possible to provide a positioning mechanism.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
FIG. 1 shows a desk provided with legs 1 that are panel structures to which a cover positioning mechanism according to this embodiment is applied. This desk has a structure in which a pair of legs 1 and 1 are connected by a top plate 2 and a back plate 3 that also serve as reinforcing members.

  2 shows the side and front of the leg 2 together with the lower surface of the stay 12 and the upper surface of the base 13 constituting the leg 2, and FIG. 3 shows the internal structure of the leg. As shown in these drawings, the leg 1 includes the stay 12 and the base 13 that extend forward from both upper and lower ends of the leg support 11, and the leg support 11 includes a front reinforcing member 11a and a rear reinforcing member 11b. The stay 12 has an upper reinforcing member 12a and the base 13 has a lower reinforcing member 13a. A lightweight core material 14 such as a paper honeycomb core is disposed in a portion surrounded by the reinforcing materials 11a, 11b, 12a, and 13a. The reinforcing materials 11a, 11b, 12a, and 13a and the lightweight core material 14 are connected to the lightweight core material 14 shown in FIG. A pair of steel plates 15 are attached by pressure bonding from a direction perpendicular to the paper surface.

  That is, the leg 1 which is a panel structure is surrounded so as to be wrapped by the steel plate 15 with the side surface as a base point, thereby providing both upper and lower end surfaces of the stay 12, upper and lower end surfaces of the base 13, and front and rear end surfaces of the leg support 11. Then, the bent pieces 15a, 15b, 15c of the steel plate 15 are wound around, and the joint 16 is finished between the bent pieces 15a-15a, 15b-15b, and 15c-15c. The shape of the leg 1 in this embodiment is a plate shape in which the leg support 11 extends linearly in the vertical direction, and extends from the vicinity of the upper and lower ends in the direction in which the stay 12 and the base 13 intersect. The upper entry corner 1x that is the boundary between the leg column 11 and the stay 12 and the lower entry corner 1y that is the boundary between the leg column 11 and the base 13 are curved, and the upper surface 12a of the stay 12 and the lower surface 13b of the base 13 are curved. Is formed in a straight line perpendicular to the leg support 11, and the lower surface 12b of the stay 12 and the upper surface 13a of the base 13 are inclined in the direction in which the distance between the two increases toward the protruding end.

  In this embodiment, a portion extending from the upper surface of the base 13 to the lower entry corner 1y, a front surface 11a of the leg support 11, and a portion extending from the upper entry corner 1x to the lower surface 12b of the stay 12 are respectively made up. 4, the stay cover 4 a, the base cover 4 b, and the column cover 4 c are attached so that the side surface and the back surface thereof are written together.

  For this purpose, a rectangular window 17 is formed in an intermittent position along the joint 16 as shown in FIG. It exists on both sides of the joint 16.

  On the other hand, in each cover 4a-4c, as shown in FIG.4 and FIG.5, the tongue piece 41 which is the 1st insertion piece inserted in the said joint 16, and the 2nd insertion piece inserted in the said window 17 are shown. The elastic claw 42 is provided.

  The tongue piece 41 protrudes from the center in the width direction on the back surface of each of the covers 4a to 4c, and is integrally molded with each cover 4a to 4c so as to exist at an intermittent position along the joint 16.

  Each of the elastic claws 42 forms a pair at a position displaced from the center in the width direction on the back surface of each cover 4a to 4c to both sides, and the pair of elastic claws 42 is in an intermittent position along the longitudinal direction of each of the covers 4a to 4c. Specifically, as shown in FIGS. 2 and 4, they are provided at positions corresponding to the windows 17. The elastic claw 42 also serves as a mounting piece for engaging the covers 4a to 4c with the windows 17 of the bent pieces 15a to 15c so as not to drop off. And the whole circulates in the shape of a loop and exhibits the outer shape of the nail. The elastic claws 42 are integrally molded with the covers 4a to 4c.

  As shown in FIG. 4, the number of tongue pieces 41 is smaller than the number of elastic claws 42, and they are provided at intervals of approximately one. Along with the longitudinal direction of each cover 4a-4c, the longitudinal position where the tongue piece 41 is provided substantially coincides with the longitudinal position where the elastic claw 42 is provided, with some exceptions.

  When the front-rear direction of the leg 1 is taken as a reference, the elastic claw 42 attached to the base cover 4b has a rearward hook shape, and the elastic claw 42 attached to the support cover 4c has a downward hook shape, and is attached to the stay cover 4a. The claw 42 has a rearward saddle shape, the base cover 4b is slid rearward after inserting the elastic claw 42 into the window 17, and the column cover 4c is slid downward after inserting the elastic claw 42 into the window 17. The cover 4a is attached by inserting the elastic claw 42 into the window 17 and sliding it backward.

  The cover attachment procedure in this embodiment is set in the order of the base cover 4b, the column cover 4c, and the stay cover 4a as shown in FIGS. 6 (a) → (b) → (c). Between the lower end of the column cover 4c and the rear end of the base cover 4b, as shown in FIGS. 6B and 7, there is an elastic projection 4c1 that can be engaged by inserting the column cover 4c from above or obliquely upward. The opening 4b1 is elastic between the rear end of the stay cover 4a and the upper end of the column cover 4c so that the stay cover 4a can be engaged from the front as shown in FIGS. A protrusion 4a1 and a recess 4c2 are formed respectively. A front end cover 4d for blinding the opening end of the base 13 shown in FIG. 2 is provided at the front end of the base cover 4b shown in FIG. 6, and an opening end of the stay 12 shown in FIG. 2 is provided at the front end of the stay cover 4a shown in FIG. The front end cover 4e for blinding is attached detachably.

  In the cover-attached state, as shown in FIG. 5, the tongue piece 41 is inserted into the joint 16 and the elastic claw 42 is inserted into the window 17, respectively. For example, the reference thickness dimension d of the leg 1 in this embodiment is If it is assumed that the tolerance is set to 38 mm and the tolerance is +1 mm and −0.5 mm, the bending pieces 15a to 15a (between 15b to 15b and 15c to 15c) are compared with the state with the tolerance of 0 in FIG. When the minus tolerance is narrowed as indicated by an arrow Z1 in the figure, the tongue piece 41 can be closely inserted into the inner edge 16a of the joint 16, and between the bent pieces 15a-15a (between 15b-15b, 15c- 15c) so that the elastic claw 42 can be closely inserted into the opening edge 17a on the inner side of the window 17 when it is widened by a plus tolerance as indicated by an arrow Z2 in the figure. Width, width of tongue 41, window 1 Opening position and opening size, width and mounting position of the elastic claw 42 is set.

  Therefore, when the covers 4a to 4c are displaced in the width direction at the mounting position, the joint width varies due to processing between the bent pieces 15a-15a (between 15b-15b, 15c-15c), assembly errors, and the like. Even if this occurs, the covers 4a to 4c can be attached, and the tongue piece 41 is preferentially engaged with the opening edge of the joint 16 or the elastic claw 42 is preferentially engaged with the opening edge of the window 17. Thus, the positional deviation of the covers 4a to 4c is effectively restricted.

  As described above, the cover positioning mechanism according to the present embodiment covers the position between the bent pieces 15a-15a (between 15b-15b and 15c-15c) that are a pair of adjacent members via the joint 16. When attaching 4a-4c, while forming the window 17 in each of the bending pieces 15a, 15b, 15c of each steel plate 15 located on both sides of the joint 16, the first is inserted into the joint 16 in each cover 4a-4c. When the cover 4a to 4c is about to be displaced in the width direction at the mounting position, the tongue piece 41 as the insertion piece and the elastic claw 42 as the second insertion piece inserted into the window 17 are provided. A mode in which the tongue piece 41 as the first insertion piece preferentially engages with the opening edge of the joint 16 and the elasticity as the second insertion piece according to the fluctuation in the joint width caused by assembly errors or the like. The opening of the window with priority on the nail 42 Those configured as capable of taking a manner that mutually relate to.

  For this reason, even if the joint width fluctuates depending on the lot or the joint width fluctuates for each location of the member, the positioning function can be secured against any variation of expansion or contraction. For this reason, the positioning function is optimized while ensuring the ease of attaching and detaching the covers 4a to 4c, and the adhesion of the covers 4a to 4c to the legs 1 as members can be kept good. Of course, even when a minute expansion / contraction, deflection, or the like occurs on the covers 4a to 4c side, there is an effect of effectively absorbing this.

  In particular, the elastic claw 42, which is the second insertion piece, also serves as a mounting piece for engaging the covers 4a to 4c with the windows 17 of the bent pieces 15a to 15c so that they can be inserted mischief. By avoiding an increase in the number of locations, it is possible to achieve both good operability and an attached state.

  Moreover, since the elastic nail | claw 42 which is a 2nd insertion piece is provided in the intermittent position along the joint 16 with the window 17, it can set an insertion position suitably and can ensure attachment / detachment ease. .

  Similarly, since the tongue piece 41 which is the first insertion piece is also provided at the intermittent position along the joint 16, it avoids the inconvenience that it becomes difficult to insert the insertion piece continuously, and is attached and detached. Ease can be ensured.

  In the above, if the tongue piece 41 as the first insertion piece and the elastic claw 42 as the second insertion piece are separated from each other, the bending of the covers 4a to 4c between them causes a positioning error. Since these longitudinal positions are aligned as much as possible, the positioning function as initially set can be effectively exhibited.

  In particular, the member of the present embodiment is a steel plate 15 in which bent pieces 15a, 15b, and 15c are wound on end surfaces, and covers 4a to 4c are attached to positions covering the end surfaces, and bending processing is performed. Then, there is a situation in which an error is likely to occur in the positions of the bent pieces 15a, 15b, and 15c on the end face, and consequently, the joint width. Therefore, it may be extremely useful to apply this embodiment.

  In addition, the steel plate 15 is pressure-bonded to both side surfaces of a lightweight core material 14 such as a paper honeycomb core and constitutes the leg 1 which is a panel structure together with the lightweight core material 14. When sandwiching with the steel plate 15 under the pressure bonding process, there is a situation in which errors are likely to occur in the positions of the bent pieces 15a, 15b, 15c of the steel plate 15 and consequently the joint width due to the variation in the thickness of the structure. Also in this respect, it can be extremely useful to apply the present invention.

  When the distance between the mounting pieces 15a-15a (between 15b-15b and 15c-15c) is narrowest within a tolerance range that is allowed in advance, the tongue piece 41 as the first insertion piece is in close contact with the joint 16. The elastic claw 42, which is the second insertion piece, can be closely inserted into the window 17 when the space between the attachment pieces 15a-15a (between 15b-15b, 15c-15c) is widest. Therefore, it is possible to achieve both a proper mounting state of the cover while allowing tolerances.

  The specific configuration of each part is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit of the present invention.

  For example, in the said embodiment, although the 1st insertion piece was provided in the intermittent position along a joint, the thing of the continuous rib shape inserted along a joint may be sufficient. The intermittent first insertion piece is effective in ensuring the ease of attaching and detaching the cover, and also saves on material costs. However, if it is a continuous rib, the rigidity of the cover is improved, and the shape of the cover And the effect of stabilizing the mounting state can be expected.

  Moreover, in the said embodiment, although the 2nd insertion piece served as the role of the attachment piece which engages so that a cover may not drop | omit to the window of a member, a 2nd insertion piece is the said attachment piece. The thing of the form provided integrally may be sufficient.

  Furthermore, the first insertion piece may also serve as an attachment piece for engaging the cover with the member so as not to drop off, or the attachment piece may be provided integrally. For example, as shown in FIG. 9, the first insertion piece 141 is provided with a retaining portion 141 a to provide an attachment function to the joint 16, and the second insertion piece 142 is simply inserted into the window 17. Only a positioning function may be provided in a tongue-like shape. Even if comprised in this way, according to the fluctuation | variation of joint width, the 1st insertion piece 141 gives priority to the opening edge 16 of the joint 16, and the 2nd insertion piece 142 has priority. It is possible to effectively realize the mode of engaging with the opening edge 17a of the window 17. Such a configuration includes a configuration in which the first insertion piece 141 is engaged with the opening edge 16 of the joint 16 from the beginning of the cover installation.

  Furthermore, the present invention can also be applied to a top plate or the like as a panel structure, and can be used for other applications besides the panel structure.
