Description

  The present invention relates to a connection structure in which ends of plate-like members or rod-like members such as headboards are connected to each other via a connection member, and a connection member.

  Kasagi is used as a handrail for staircases, a decorative plate for staircase walls, and the like by being fixed to staircases such as stairs and landings.

For example, the staircase wall provided in the elevator port has a substantially vertical end surface and a substantially horizontal upper surface or an upper surface having a gradient of 35 ° with respect to the horizontal plane continuously from the end surface. For this reason, the two caps are arranged so as to cover the end surface and the upper surface of the staircase wall at an arrangement angle of 90 ° or 125 °, respectively.
In addition, for example, a staircase wall provided at a landing has a straight, substantially horizontal upper surface, or a substantially horizontal upper surface that is refracted at 90 °. For this reason, the two headboards are arranged so as to cover the upper surface of the staircase wall at an arrangement angle of 180 ° or 90 °, respectively.

  Conventionally, a connection structure has been proposed in which the end faces of the two caps arranged in this way are connected by a connecting member, and further, the end of the cap is covered with this connecting member to improve the beauty (Patent Document 1). , 2).

In the 1st connection structure currently indicated by patent documents 1, the connection member (headwood connection member) in which the slot part in which the edge part of each two rectangular-plate-shaped headboards is inserted is formed. . The arrangement angle between the bottom surfaces of the groove portions corresponds to the arrangement angle of the headboards, and the headboards are connected to each other by abutting the end surfaces of the headboards with the bottom surfaces of the groove portions of the connecting member. It is made up by covering.
Here, the end face of the headboard is substantially perpendicular to the front face and the rear face of the headboard regardless of the arrangement angle of the headboard.

  However, such a connection member has a problem that the number of types of connection members increases because connection members having different shapes are required for each angle of the headboard and for each headboard having a different width.

  For example, when using a headboard having four types of widths and connecting a vertical headboard and a headboard arranged with an arrangement angle of 90 ° or 125 ° to the headboard, eight types of connecting members are required, For this reason, eight types of molds for forming the connection member are required.

FIG. 16 is a side view of a conventional connection structure.
In order to reduce the types of connection members, the connection member (headwood connection member) 9 in the second connection structure disclosed in Patent Document 1 includes a main body 901 and two end covering members 902 and 902 (1 Only shown).
The two rectangular plate-shaped headboards B1 and B2 are arranged such that the headboard B1 is arranged vertically, and the headboard B2 has a slope of 45 ° with respect to the horizontal plane, that is, an angle of 135 ° with respect to the headboard B1. It distribute | arranges to the end surface W1 and the upper surface W2, respectively.

The main body 901 has groove portions 91 and 92 into which end portions of the caps B1 and B2 are inserted. The arrangement angle between the bottom surfaces of the groove portions 91 and 92 is 45 °.
Each end covering member 902 has a plate shape having an area larger than the cross-sectional area of the main body 901. At both ends of the main body 901, holes 93, 93 (only one is shown) into which the convex portions 94 formed on one surface (back surface) of the end covering member 902 are inserted are formed. By inserting the convex portions 94, 94 into the holes 93, 93 with the surface of 902 facing outward, the end covering members 902, 902 are attached to the main body 901 as indicated by a two-dot chain line in the figure. Cover both ends.

The caps B1 and B2 are connected by abutting the end surfaces of the caps B1 and B2 on the bottom surfaces of the grooves 91 and 92.
Further, the end portions of the caps B1 and B2 are made by covering the end portions of the caps B1 and B2 with the wall portions 91a and 92a of the groove portions 91 and 92 and the end covering member 902.

  Such a connection member 9 can cope with the headboards B1 and B2 having different widths by cutting the main body 901 and adjusting the length of the main body 901 according to the width of the headboards B1 and B2. Moreover, since the end portion of the main body 901 is covered with the end portion covering member 902, the aesthetic appearance of the cut end portion of the main body 901 can be improved.

For example, when using the headboards B1 and B2 having four kinds of widths and connecting the vertical headboard B1 and the headboard B2 arranged with an arrangement angle of 90 ° or 125 ° with respect to the headboard B1, Two types of the main body 901 and the end covering member 902 of the member 9 may be prepared.
As a result, the types of molds for forming the connection member are reduced.

However, the end faces of the headboards used in the first and second connection structures of Patent Document 1 are substantially perpendicular to the front and back surfaces of the headboards regardless of the headboard placement angles, and according to the headboard placement angles. No mention is made of the case where the end face of the headboard is inclined.
Further, for example, there is no mention of a case where the horizontal headboards B1 and B2 arranged with an arrangement angle of 90 ° are connected to each other via the connection member 9 used in the second connection structure.

By the way, in the connection structure currently disclosed by patent document 2, the connection member (for headboards) provided with the head substantially the same shape as the outer periphery of a headboard, and the flat insertion part which has this head on an outer periphery. (Joining member) is used. In this connection structure, the caps are connected to each other by inserting the insertion part of the connection member between the end surfaces of the two caps, and the end of the cap is covered by covering the end of the cap with the head of the connection member. Make up.
In such a connection structure, when the headboards are arranged in a substantially straight line, a headboard whose end face is substantially perpendicular to the front surface and the rear surface is used, and the headboard is arranged with an arrangement angle of 90 °, 125 °, or the like. In this case, a headboard whose end face is inclined according to the arrangement angle is used. That is, the end faces of the two headboards are connected in a state of facing each other substantially in parallel.

  Double-sided tapes T and T are arranged between the insertion part 25 and the end surfaces 51a and 52a, and the insertion part 25 is fixed (fixed) to the end surfaces 51a and 52a.

  As shown in FIG. 3, the insertion plate portion 21 and the insertion portion 25 are juxtaposed along the end surfaces 51 a and 52 a of the headboards 51 and 52. For this reason, the separation distance between the end faces 51a and 52a is substantially equal to the sum of the thickness of the insertion plate portion 21 (or the insertion portion 25) and the thickness of the double-sided tape T for two sheets.

  In the case of configuring the connection structure 11 as described above, the operator can use the caps 51 and 52 having end faces 51a and 52a, two injection-molded end decorative members 24 and 24, and an extrusion-molded connection makeup. Prepare the parts. This connecting decorative member is longer than the length of one side in the width direction of the caps 51 and 52, and the operator prepares the connecting decorative member 20 by cutting the connecting decorative member according to this length.

Since the end surface 22a, 22a and the end surfaces 21a, 21a are covered with the end decorative members 24, 24 later, the end of the connecting decorative member 20 is the end of the connecting decorative member when the connecting decorative member is cut. It is not necessary to cut with strict accuracy. That is, the length of the connecting decorative member 20 may be slightly shorter than the length of one side in the width direction of the caps 51 and 52, and the end surface 22a, the end surface 21a, and the like may be rough. That is, the connection member 2 has improved workability when preparing the connection decorative member 20.
This is a significant difference from the conventional connection structure shown in FIG. Since the end cover members 902 and 902 of the connection member 9 are directly attached to the main body 901, the length, end shape, etc. of the main body 901 require high accuracy.

  An operator who has prepared the caps 51 and 52, the connecting decorative member 20, and the end decorative members 24 and 24, for example, first has an end surface 611 of the staircase wall 61 with the front surface 51 c on the front side and the end surface 51 a on the upper surface of the staircase wall 61. The headboard 51 is attached to the 612 side.

Next, the operator prepares the connecting decorative member 20 in which the double-sided tapes T and T are fixed to the both surfaces of the insertion plate portion 21, and on one side of the surface covering portion 22 along one side in the width direction of the headboard 51. One surface of the insertion plate portion 21 is fixed to the end surface 51a with the double-sided tape T while covering the end surface 51b.
Further, the operator prepares the end decorative members 24 and 24 in which the double-sided tape T is fixed to both surfaces of the insertion portions 25 and 25, and the one side portions 261 and 261 and the other side portions 262 of the member covering portions 26 and 26. , 262 covers the end surfaces 22a and 22a and the end surfaces 21a and 21a, and fixes one surface of the insertion portions 25 and 25 to the end surface 51a with double-sided tape T and T.

  Finally, the worker attaches the headboard 52 to the upper surface 612 of the staircase wall 61 with the surface 52c facing the front side and the end surface 52a facing the end surface 611 of the staircase wall 61. However, when attaching the headboard 52, the operator does not shift the positions of the connecting decorative member 20 and the end decorative members 24, 24 fixed to the headboard 51, and is arranged along one side in the width direction of the headboard 52. Accordingly, while covering the end surface 52b on the other side of the surface covering portion 22, the end surface 52a is covered with the other surface of the insertion plate portion 21 to which the double-sided tapes T, T,. Hit the other side.

The caps 51 and 52 are connected by the connection structure 11 as described above. At this time, the longitudinal directions of the caps 51 and 52 have an arrangement angle of about 125 °, and the end surfaces 51a and 52 52a opposes substantially parallel.
Further, the connecting decorative member 20 makes up the end surfaces 51b and 52b of the headboards 51 and 52, and further conceals the upper gap between the end surfaces 51a and 52a.
Furthermore, the end decorative members 24, 24 make up the end surfaces 22a, 22a and the end surfaces 21a, 21a of the connection decorative member 20. Further, the other side portions 262, 262 of the end decorative members 24, 24 blind the side gaps between the end surfaces 51a, 52a, and make up the end portions of the side surfaces of the caps 51, 52.

  Further, even when a small step is generated in the caps 51 and 52 when the caps 51 and 52 are attached, the steps can be hidden by the connecting member 2.

In this way, the connection structure 11 covers both the sharp edges of the caps 51 and 52 to improve tactile sensation and safety, while at the same time improving workability and aesthetics.
Further, the tactile sensation and safety when the curved surface 22b of the surface covering portion 22 and the other side portion 262 of the member covering portion 26 which is a bending portion touch the connecting member 2 are improved.

Note that the fixing of the insertion plate portion 21 of the connecting decorative member 20 and the insertion portions 25, 25 of the end decorative members 24, 24 to the end faces 51a, 52a is not limited to the double-faced tape T, T,. Or a plurality of fixing means may be used in combination.
Moreover, the attachment procedure of the caps 51 and 52, the connecting decorative member 20, and the end decorative members 24 and 24 is not limited to the attachment procedure of the present embodiment.

  For example, first, caps 51 and 52 are attached to the end surface 611 and the upper surface 612 of the staircase wall 61 so that the end surfaces 51 a and 52 a are separated from each other by an appropriate length and are opposed to each other in parallel. The connecting decorative member 20 to which the caps 51 and 52 are applied is prepared, and the end surfaces 51b and 52b are covered with the surface covering portion 22 along one side in the width direction of the caps 51 and 52 from the surfaces 51c and 52c side of the caps 51 and 52.
