Abstract

<P>PROBLEM TO BE SOLVED: To provide a connecting structure capable of enhancing assemblability while securing connection strength, and fittings. <P>SOLUTION: When a load acts in the direction of separation of outdoor and indoor members 11A and 11B connected to each other, a crossing portion 35 turned inside an engaging recess 24 is protruded so that an engaging protrusion 32 can be prevented from coming off the engaging recess 24. Since an extended portion 34 of the engaging protrusion 32 and a bent portion 36 thereof resist the load by a tensile force, the connecting strength can become higher than that of such a connecting structure as to maintain engagement by bending rigidity thereof. Thus, a sufficient connecting strength can be acquired even when a cross section of the engaging protrusion 32 is not expanded. Then, when the outdoor and indoor members 11A and 11B are assembled, a force for inserting the engaging protrusion 32 into the engaging recess 24, while elastically deforming the engaging protrusion 32, can be decreased for an improvement in the assemblability. <P>COPYRIGHT: (C)2011,JPO&INPIT

  However, in the conventional connection structures described in Patent Documents 1 and 2, if the elastic engagement portion and the elastic engagement portion are provided on the opening side for holding the glass, interference between the resin bottle and the glass is avoided. However, a load such as wind pressure acting on the glass is supported by the elastic engaged portion, and it is necessary to firmly engage the elastic engaged portion in order to secure the connection strength. For this reason, when engaging with a change such as increasing the allowance between the elastic engagement portion and the elastic engaged portion or increasing the plate thickness to reduce the deformation of the elastic engaged portion. Since it is necessary to apply a large force, there is a problem that the assemblability is deteriorated even in this case.

  The objective of this invention is providing the connection structure and joinery which can improve assembly property, ensuring connection intensity | strength.

  The connection structure of the present invention is a connection structure for connecting the first member and the second member to each other, and the first member is formed with an engaging convex portion protruding toward the second member, The second member is formed with an engagement recess capable of receiving the engagement protrusion, and the engagement protrusion extends from the first member toward the inside of the engagement recess. The engaging recess is formed in such a manner that the engaging recess extends inward from the opening and is opposed to one another and the other facing surface portion. And a projection provided on the opening side of the opposing surface portion of the projection, and in a state where the engagement projection is inserted into the engagement recess, one end of the intersecting portion is the projection. And a force in a direction to separate the first member and the second member is applied. There are, the intersecting portion in the fulcrum the one side end portion by rotating, characterized in that the other end portion of the crossing portion is configured to abut to the other opposing surface.

  According to the present invention described above, since the one end of the intersecting portion is engaged with the protrusion by inserting the engaging convex portion into the engaging concave portion, the first member and the second member are pressed against each other. As a result, it is possible to improve the workability of the assembly work. Even when a force (separation force) is applied in the direction in which the first member and the second member are separated from each other, the other end portion of the intersecting portion rotated with the one end portion as a fulcrum contacts the other opposing surface portion. By contacting, the intersecting portion is stretched between the opposing surface portions, and the engaging convex portion can be prevented from coming out of the engaging concave portion or difficult to come off. Therefore, when the intersecting portion is stretched between the opposing surface portions, it is possible to obtain a connection strength greater than the connection strength engaged with the projection portion due to the bending rigidity of the extending portion and the intersecting portion, and the cross section of the engaging convex portion is enlarged. Therefore, when the first member and the second member are assembled, a large force can be made unnecessary so that the assembling property is not hindered.

At this time, in the connection structure of the present invention, the intersecting portion of the engaging convex portion intersects the extending portion at an acute angle toward the one side end portion and the extension toward the other side end portion. It is preferable that it is formed so as to intersect the part and an obtuse angle.
According to such a configuration, the projecting portion is inserted into the engaging recess by inclining the intersecting portion so that the one end portion intersects the acute direction with respect to the extending direction of the extending portion. The pushing force at the time of engaging with can be suppressed, and the assemblability can be further improved. In addition, when the crossing portion is rotated by the separation force acting by inclining the crossing portion so that the other end portion intersects the obtuse angle with respect to the extending direction of the extending portion, the other side end portion is the other It is possible to make it easier to contact by rotating in the direction approaching the opposite surface portion, and to strongly press the other side end portion against the other opposite surface portion to increase the connection strength.

Furthermore, in the connection structure of the present invention, it is preferable that a bent portion bent on one side is formed at the distal end of the extending portion, and the intersecting portion is provided at the distal end of the bent portion.
According to such a configuration, the extending portion and the intersecting portion are connected via the bent portion, so that at the time of assembly, the bent portion bends so that one end portion of the intersecting portion can easily get over the protruding portion. Thus, the assembling property can be improved. In addition, with respect to the pulling force, the bent portion and the extending portion become a shape that approaches a straight line, and compared with the shape before the pulling force acts, the intersecting portion and the extending portion that are stretched between the opposing surface portions Is deformed so as to approach the orthogonal direction, it is possible to resist the pulling force by the pulling force of the extending part, and it is difficult for bending stress to be generated in each part of the engaging convex part, thereby further improving the connection strength. it can.

In the connection structure of the present invention, a locking portion and a locked portion that can be locked to each other are formed at positions separated from the engaging convex portion and the engaging concave portion in the first member and the second member. The locking portion is locked to the locked portion, the first member and the second member are rotated relative to each other with the locking position as a fulcrum, and the engaging convex portion is inserted into the engaging concave portion. And it is preferable that the said 1st member and the 2nd member are connected by engaging the one side edge part of the said cross | intersection part with the said projection part.
According to such a configuration, the first member and the second member are relatively rotated while the locking portion and the locked portion are locked, and the engaging convex portion is inserted into the engaging concave portion to intersect. By engaging one end portion of the portion with the protruding portion, special positioning or the like is unnecessary, and the assembly operation can be performed easily and reliably.

Furthermore, in the connection structure of the present invention, the locking portion and the locked portion may be provided at a position where the distance from the other side end is shorter than the distance from the one side end. preferable.
According to such a configuration, it is possible to increase the distance (working distance) between the locking position of the locking portion and the locked portion and the engaging position of the one end portion of the protrusion and the intersecting portion. Since the one end of the intersection is positioned outside the track that relatively rotates the second member with the locking position as a fulcrum during assembly, the protrusion is formed by inclining the intersection as described above. The sliding contact angle at the intersection when getting over can be made shallow, the sliding contact resistance can be reduced, and the pushing force can be further suppressed.

On the other hand, the joinery of the present invention is a joinery comprising a frame and a face member supported by the frame, and is at least one of the frame member constituting the frame and the frame member constituting the face member. One frame member has the 1st member and 2nd member which were connected with the connection structure in any one of Claims 1-5, It is characterized by the above-mentioned.
According to such a configuration, as in the connection structure described above, the frame member and the face material including the frame material are assembled while ensuring the connection strength between the first member and the second member constituting the frame material. Can be improved.

At this time, in the joinery of the present invention, the first member is a resin indoor member in which an engagement convex portion is formed, and the second member is a metal outdoor member in which an engagement concave portion is formed. Preferably there is.
According to such a configuration, the engagement protrusion is formed by forming the engagement protrusion on the resin indoor member (first member) having a lower elastic modulus than the metal outdoor member (second member). It is possible to suppress the pushing force when the is inserted into the engaging recess and engaged with the protrusion. Furthermore, the crossing portion can be easily rotated even when a pulling force is applied, and the connection strength can be reliably improved.
