Description

  The present invention relates to a joint holding device having support pillars on which panels can be arranged on both sides, and joint members detachably attached to the front surfaces of the support pillars so as to be sandwiched between side end portions of both panels. .

  As a method of disposing a panel on an existing wall, a method of disposing a plurality of support columns on an existing wall and fixing the panel between adjacent support columns is employed. A joint member for concealing the gap, that is, the exposed portion of the support column, is attached between the panels thus attached (see, for example, Patent Document 1).

  FIG. 10 is a perspective view showing an example of a conventional holding structure for this type of joint member. For the convenience of explanation, this figure shows a perspective view seen from the back side of the support column.

  In the illustrated example, an opening 101 for attaching the joint member 110 is formed along the longitudinal direction on the front surface (the upper surface in the drawing) of the hollow support column 100.

  On the other hand, the joint member 110 includes a pair of fitting pieces 112 extending from the back surface of the main body 111. A locking portion 112 a is provided at the tip of the fitting piece 112, and the joint member 110 can be attached to the gap between the panels 3 by locking the locking portion 112 a to the opening edge 102 of the support column 100. It is like that. Specifically, a guide surface 112b is formed on the engaging portion 112a of the fitting piece 112, and the guide surface 112b is applied to the opening edge 102 and inserted into the groove space while bending the fitting piece 112 inward. Thus, the locking portion 112 a is locked to the opening edge 102.

  Note that the two pieces of the joint member 110 that are formed so as to extend obliquely toward the side end surface of the panel 3 are wing pieces 113 that are elastically deformed by mounting the joint member 110 between the panels 3. Regardless of the dimensional error between 3 and 3, the gap can be hidden.

  However, in the above-described structure, the fitting piece 112 of the joint member 110 and the opening 101 of the support column 100 that are in a fitting relationship are both long in length over the entire length of both members. A strong force is required to elastically deform the fitting piece 112. Therefore, it is very difficult to attach the joint member 110. Further, it is more difficult to remove the joint member 110 because there is no portion that facilitates elastic deformation such as a guide surface during attachment.

  In order to easily lock the locking part, it is possible to assume that the fitting pieces are not formed over the entire length of the support column but are distributed at multiple locations, but the support column is cut according to the height of the panel Therefore, it is difficult to specify the formation position of the fitting piece.

  The present invention has been proposed in view of the above circumstances, and an object thereof is to provide a joint holding device in which a joint member can be easily fixed to a support column and can be easily removed.

And a locking projection that is locked to the support column . The support column includes a locking receiving portion that locks the locking projection of the joint holder. The joint member is held through the joint holding part of the joint holder that is fixedly fixed, and the support column is a groove space formed by the opening, both side walls, and the bottom along the longitudinal direction. A pair of sandwiching pair pieces that are opposed to each other in the groove space are formed to protrude on both side walls. The lock receiving portion is configured to include a groove space and a pair of sandwiched pair pieces. The lock protrusion includes a rear protrusion protruding rearward and a pair of side protrusions protruding on both sides of the support column. And the rear protrusion is inserted into the groove space, and each of the pair of side protrusions is sandwiched by each of the pair of sandwiching pair pieces, whereby the joint holder is fixed to the support column. With the structure having a pair of side projections oriented in the direction in which the support column opening is formed, the locking projection of the joint holder is directed toward the bottom of the groove space, and the tip of the rear projection Is inserted until it touches the bottom, the position where the side protrusion is clamped is determined, the joint holder is rotated approximately 90 degrees, and each of the pair of side protrusions is mounted between each clamping pair It was made to do.

Furthermore, in the present invention, each of the pair of side protrusions may be formed in a plate shape, and at least one of the tip corners may be formed in a round shape.

  Embodiments of the present invention will be described below with reference to the accompanying drawings.

  1-8 is explanatory drawing regarding an example of the joint holding | maintenance apparatus which concerns on one Embodiment of this invention.

  The joint holding device 1 is detachably attached so as to be sandwiched between the side end portions 3a and 3a of the panels 3 and 3 in the panel holding device 2 configured to hold the panel 3 using the support pillars 10. It is a device that holds the joint member 30.

  As shown in FIG. 2, the panel holding device 2 is configured such that support pillars 10 extending in the vertical direction are arranged in parallel on the surface of the wall 4 so as to be sandwiched between the upper and lower frame parts 5 and 5. Is done. And the panel 3 is hold | maintained between the support pillars 10 and 10 provided adjacently. The panel 3 is fixed to the support column 10 using various fixing brackets (not shown).

  That is, as shown in FIG. 1, two panels 3 are arranged and fixed to one support column 10 on both sides thereof. The support pillars 10 and the like are erected as shown in FIG. 2, but FIGS. 1 and 3 to 7 show perspective views of the horizontal state as viewed from above for convenience of explanation. The arrow F in FIG. 1 indicates the front. Based on this direction, the front and rear directions are defined, and the names of the constituent parts of the joint holding device 1 (support column 10 and joint holder 20) are defined.

  The joint member 30 is detachably attached so as to hide a gap between the side end portions 3a and 3a of the two panels 3 and 3 and located in front of the support column 10. In addition, as the joint member 30, the thing with the full length dimension of the longitudinal direction corresponding to the dimension of the longitudinal side of the panel 3 may be used, and what was divided | segmented into multiple along the longitudinal direction may be used.

  The joint member 30 includes a main body portion 31 having a concavo-convex pattern on the front surface, a pair of wing pieces 33 and 33 projecting obliquely rearward from the both side ends toward the side end surface of the panel 3, and the rear surface of the main body portion 31. And a pair of fitting pieces 32, 32 extending rearward from both side ends.

  The fitting piece 32 is a part for fixing the joint member 30 to the support column 10, and the front end (rear end) is a member for locking and fixing to the joint holder 20 fixed to the support column 10. A pawl 32a (see FIG. 6) is formed.

  In addition, the wing piece 33 is formed of an elastic piece that is elastically deformed by mounting the joint member 30 between the panels 3 and 3. It is configured to hide the gaps without any gaps.

  The joint holding device 1 includes a support column 10 and a plurality of joint holders 20 that directly hold the joint member 30.

  Details will be described below.

  The example shown by this embodiment has the structure which has the opening 13 in the front surface of the support pillar 10, and latches and fixes each of several joint holders 20 with respect to the groove space 12 formed along the longitudinal direction. It has become.

  The groove space 12 is formed by an opening 13, both side walls 14, 14, and a bottom portion 15. Opposite pieces 16 b facing each other between the side walls 14, 14 are formed on both side walls 14, 14. The opening edge piece 16a is formed so as to protrude in parallel and substantially the same length. The opposing piece 16b and the opening edge piece 16a constitute a holding pair piece 16 that holds and fixes the side protrusion 22 of the locking protrusion 21 of the joint holder 20 described later. That is, the groove space 12, the clamping pair 16, and the like constitute the locking receiving portion 11 that locks the locking protrusion 21 of the joint holder 20.

  The support column 10 is formed in a width dimension in consideration of the strength for fixing the panel 3. However, in order to lock and fix the joint holder 20 as will be described later, the support pillar 10 has a dimension of the joint holder 20. Correspondingly, a side wall 14 is formed from the outer wall 17 through a lightening space.

  On the other hand, the joint retainer 20 has a cross shape in front view as shown in FIGS. 3A, 4 and 5, and joint joint fixing portions 25 projecting forward (upward in the figure) and projecting to both sides. It has a shape having a pair of side protrusions 22, 22 and a rear protrusion 23 protruding rearward. Of these parts, the side protrusions 22, 22 and the rear protrusion 23 constitute a locking protrusion 21 that is locked to the locking receiving portion 11 of the support column 10.

  Of each part of the joint holder 20, first, a structure (locking protrusion 21) that is fixed to the support column 10 will be described.

  The side projection 22 of the locking projection 21 has a substantially rectangular shape in plan view, and the dimension from the side end of one side projection 22 to the side end of the other side projection 22 is a groove space. The dimensions between the twelve side walls 14 are substantially matched.

  Moreover, one corner | angular part of the front-end | tip (side end) of each side protrusion 22 is formed in round shape. The rounded corner 22a is for facilitating the rotation operation when the joint holder 20 is mounted on the support column 10. Therefore, as shown in FIG. It is desirable to have a round shape.

  Further, on the surface side of the side protrusion 22, a plate-like elastic portion 22c extending so as to protrude obliquely from the central portion between the two edges toward the edge is a recess 22d (FIGS. 5A and 5B). ) See) It is formed in a slightly floating state from the bottom. The elastic portion 22c is for securely fixing the joint holder 20 itself after the rotation operation when the joint holder 20 is mounted on the support column 10, and is urged when the protrusion 22ca is pressed from the surface side. When the pressure is released, it is restored by elastic force. Further, as shown in the figure, it is desirable to form it at the edge portions that are symmetrical with respect to each other, and in order to facilitate the rotation operation, it is desirable that it is gently inclined and protruded. The elastic portion 22c may be formed by attaching an elastic body such as rubber to the surface of the side protrusion instead of the plate piece.

  Further, a step portion 22b is formed on the back surface side of the side protrusion 22, and the step 22b has a radius for facilitating the rotation operation, similar to the corner angle portion 22a of the side protrusion 22. A corner 22ba is formed. The dimension from the side end of one step 22b to the side end of the other step 22b substantially matches the dimension between the opposing pieces 16b, 16b facing each other in the groove space 12.

  The rear protrusion 23 of the locking protrusion 21 is formed in a rectangular plate shape, and is loosely inserted into the groove space 12 in a state where the side protrusion 22 is held between the holding pair pieces 16. In this state, the tip of the rear protrusion 23 is in contact with the bottom 15 of the groove space 12. That is, as will be described later, the rear protrusion 23 acts as a positioning portion for locking and fixing the side protrusion 22.

  On the other hand, the joint fixing part 25 of the joint holder 20 includes stopper pieces 25a and 25a that protrude in the same direction as the side protrusions 22, and locking protrusions that protrude in the same direction as each of the stopper pieces 25a and 25a. 25b, 25b.

  When the fitting pieces 32, 32 of the joint member 30 are fitted to the joint fixing portion 25, the engagement claws 32 a come into contact with the engagement convex portions 25 b and elastically expand. And each front-end | tip contacts and positions each stopper piece 25a, 25a of the joint fixing | fixed part 25, and the fitting pieces 32 and 32 are latched by the latching convex parts 25b and 25b (FIG. 5 (a)). And FIG. 6).

  Next, a procedure for attaching the joint holder 20 to the support column 10 will be described with reference to FIGS.

  7, with both side protrusions 22, 22 facing the formation direction of the opening 13 in the groove space 12 of the support column 10, the locking protrusion 21 of the joint holder 20 is placed in the groove space 12, Insert in the direction until the rear protrusion 23 hits the bottom 15 of the groove space 12.

  Next, the joint holder 20 inserted in the groove space 12 is rotated by approximately 90 degrees in the direction of the arrow Y in FIG. 7, and the side protrusions 22, 22 are respectively connected to the holding pair pieces 16 of the support column 10, Put between 16.

  Since the rounded corner portion 22ba is formed in the side projection 22 of the joint holder 20, the tip of the side projection 22 can be smoothly rotated without being caught on the side wall surface of the groove space 12. Similarly, since the rounded corner portion 22ba is formed in the step portion 22 on the back surface of the side protrusion 22, it can be easily rotated without being caught on the side end surface of the opposed piece 16b.

  As described above, since the dimension between the side ends of the side protrusions 22 and the dimension between the side walls 14 are matched and the other corner is not rounded, the side protrusions 22 are tightly arranged between the side walls 14. Once fitted, there is no risk of further rotation. In the present embodiment, both the stepped portions 22b on the back surface side of the side protrusions 22 have dimensions that can be fitted between the side ends of the opposing pieces 16b, 16b. However, in the present embodiment, the side protrusions 22 Since it is the structure fitted between the side walls 14, such a step part 22b does not need to be provided.

  In addition, since the side protrusion 22 is sandwiched between the sandwiching pair 16, there is no possibility that forward and backward displacement and rotational displacement occur after the joint holder 20 is mounted. In particular, since the elastic portion 22c acts to supplement the clamping force of the clamping pair 16, the joint holder 20 hardly moves once it is fixed in the correct position.

  Thus, the plurality of joint holders 20 are mounted and fixed at appropriate positions in the longitudinal direction of the support column 10.

  Then, after attaching the panel 3 (refer FIG. 1), the joint piece 32 of the joint member 30 is inserted into the joint holder 20 by inserting the joint member 10 between the panels 3 and 3 in the arrow Z direction of FIG. The joint member 30 is correctly mounted by being locked and fixed to the joint fixing portion 25.

  According to the configuration of the joint holding device 1 described above, since the plurality of joint holders 20 are separately attached at appropriate positions in the longitudinal direction of the support column 10, the joint member 30 can be easily fixed to the support column 10. . That is, since the joint fixing structure of the joint holder 20 for fixing the joint member 30 does not extend over the entire length of the support column 10, the fitting piece 32 is elastically deformed with a small force when the joint member 30 is mounted. be able to. Further, the joint member 30 can be easily removed. In particular, in the example of the present embodiment, since the engaging projection 25b of the joint holder 20 is formed with a small projection instead of a hook-like or claw-like one, the joint member 30 can be attached and detached more easily.

  Further, according to the joint holding device 1 of the present embodiment, the joint holder 20 includes the locking projection 21 that is locked to the support column 10, while the support column 10 locks the locking projection 21. Since the latch receiving part 11 is provided, the joint holder 20 can be fixed to the support column 10 without shifting. Since the joint retainer 20 further includes the joint retainer 25 that retains the joint member 30, the joint member 30 can be reliably fixed to the support column 10 via the joint retainer 20.

  In order to make it easier to attach the joint member 30, the fitting pieces 32 may be formed separately at appropriate positions in the longitudinal direction of the joint member 30, for example, formed only in a portion corresponding to the joint holder 20. May be.

  In addition, since the depth dimension of the groove space 12 of the support column 10 and the length dimension of the rear protrusion 23 of the joint holder 20 are matched, in the mounting operation of the joint holder 20, the side protrusion 22 and Positioning with the clamping pair 16 can be easily performed.

  In the example of the embodiment described above, the side protrusions 22 of the locking protrusions 21 of the joint retainer 20 are fixed to the support pillars 10, and the rear protrusions 23 are loosely inserted into the groove spaces 12 (as positioning pieces). However, the rear protrusion 23 may be fitted and fixed. For example, the rear protrusion 23 may be formed in a cylindrical body, and the rear protrusion 23 may be press-fitted into the opening 13 (locking receiving portion) of the support column 10.

  Further, as shown in FIG. 9, the joint retainer 20 includes two rear protrusions 23 and 23 as the locking protrusions 21, and these are formed as the locking receiving portions 11 provided on the front surface of the support pillar 10. Alternatively, it may be configured to press fit into two holes. In order to ensure press-fitting and fixing, it is desirable to form a part or the whole of the rear protrusion 23 with an elastic body.

  Since it is such a structure, the joint holder 20 can be easily attached to the support pillar 10. Since the joint member 30 has a structure in which the rear protrusion 23 is press-fitted and locked into the hole, once it is mounted, it cannot be easily removed thereafter. Further, since the joint holder 20 is fixed to the support column 10 by the two rear protrusions 23, no rotational deviation occurs.
