  For example, Patent Document 1 discloses that a metal engagement member is engaged with a longitudinal engagement groove provided on a finding surface of a resin saddle member by engaging a longitudinal engagement groove provided on the finding surface of the metal saddle member. A casing having a structure in which a resin casing is mounted on the casing is disclosed.

Japanese Patent No. 4883904

  In the case of a composite structure composed of a metal and a resin having different material characteristics as in the case of the above-mentioned Patent Document 1, for example, a phenomenon in which a resin case is contracted more than a metal case at a low temperature occurs. When the plastic ridge material of the cocoon shrinks, a gap is formed at the joint portion between the left and right vertical cocoons. At this time, in the configuration of Patent Document 1, since the resin cage material is mounted on the metal cage material by engaging the engagement groove and the engagement piece extending along the longitudinal direction, at the time of cleaning, etc. When the resin saddle material is touched, the resin saddle material may rattle in the longitudinal direction with respect to the metal saddle material. This gives the user a sense of anxiety and also poses a problem in terms of product quality.

  The present invention has been made in consideration of the above-described problems of the prior art, and can suppress the occurrence of rattling between the metal cage material and the resin cage material to ensure product quality. And it aims at providing a fitting provided with this frame.

  The casing according to the present invention has at least one extending along the longitudinal direction of the resin casing with respect to at least two engaging portions in which at least one extending along the longitudinal direction of the metallic casing is an engaging groove. A pair of housings that attach the resin casing to the metal casing by engaging two engaging pieces, respectively, and serve as side walls of the engaging groove that is one engaging portion At least one of the wall portions protrudes from a part of the wall portion in the longitudinal direction toward the inside of the engagement groove and contacts one of the engagement pieces engaged with the engagement groove. A projecting portion is provided, and at least one of the other engagement piece and the opening edge of the other engagement portion is inclined with respect to the engagement direction of the engagement piece with respect to the engagement groove. An inclined portion is provided.

  Further, the joinery according to the present invention adheres a face material to the metal frame material of the frame having the above-described structure, and holds the surface material between the metal frame material and the resin frame material. The shoji shoji was supported by an opening frame.

  According to such a configuration, the protrusion provided in the engagement groove, which is one engagement portion of the metal saddle member, abuts on one engagement piece of the resin saddle member and presses it. Since the metal cage and the resin cage are engaged and fixed, the relative displacement in the longitudinal direction between the metal cage and the resin cage is prevented. Thereby, for example, even when the resin-made glazing material shrinks more than the metal glazing material due to the influence of the environmental temperature, the resin-made glazing material is not displaced in the longitudinal direction with respect to the metal glazing material. . As a result, the occurrence of rattling between the metal brazing material and the resin brazing material can be suppressed, and high product quality can be ensured. In addition, by providing an inclined portion on at least one of the other engagement piece and the opening edge of the other engagement groove, one engagement piece is attached to the one engagement groove provided with the protruding portion. After the engagement, the other engagement piece and the other engagement groove can be smoothly engaged, and the workability of the assembly work of the housing is improved.

  In the housing according to the present invention, when the projecting portion is provided at a position offset from the opening edge of the engagement groove to the back side, the projecting portion becomes an engagement piece at the opening edge of the engagement groove. Interfering and interfering with the insertion is suppressed as much as possible.

  In the housing according to the present invention, after the projecting portion is inclined so as to project gradually from the wall surface of the wall portion toward the inside of the engagement groove in a direction along the longitudinal direction of the wall portion, By inclining so as to gradually return toward the wall surface of the wall portion, when the shape has a ridge line along the longitudinal direction of the wall portion, the fracture surface thereof is not exposed toward the opening end of the engaging groove. Therefore, when the engaging piece is inserted and engaged with the engaging groove, the projecting portion does not become a heavy load, and the assembly work efficiency is hardly affected.

  In the housing according to the present invention, at least one wall portion of the pair of wall portions protrudes inward of the engagement groove and extends along a longitudinal direction of the wall portion, and is formed on the engagement piece. It is good also as a structure which the contact piece which contact | abuts is provided and the said protrusion part was formed by making a part of longitudinal direction of the said contact piece protrude further toward the inner side of the said engagement groove | channel. If it does so, a protrusion part can be made into the state which entrapped reliably with respect to the engagement piece with the slight protrusion amount, and the process also becomes easy.

  According to the present invention, since the protrusions prevent the relative displacement in the longitudinal direction between the metal brazing material and the resin brazing material, for example, the resin brazing material is made of the metal brazing material due to the influence of the environmental temperature. Even if it is a case where it shrinks more, the resin-made saddle material does not produce a position shift in the longitudinal direction with respect to the metal-made saddle material. As a result, the occurrence of rattling between the metal brazing material and the resin brazing material can be suppressed, and high product quality can be ensured.

Specifically, the inclined surface 41b has a shape that reduces the catch of the engaging claw 41a on the opening edge of the engaging groove 39 by gradually inclining toward the rear side in the engaging direction. For this reason, the engagement piece 41 can be more smoothly inserted into and engaged with the engagement groove 39 provided with the protrusion 72. Such an inclined surface 41b may be provided on the front end surface of the engagement piece 41 in the engagement direction, may be provided on the opening edge of the engagement groove 39, or may be provided on a part or all of them. In the case of this configuration example, if the inclined surface 40a is provided at least on the engagement piece 40 to be engaged later, the metal cage 30 and the resin cage 32 can be smoothly engaged. The inclined surface 41b of the engaging piece 41 to be made may be omitted.

  6 is an enlarged vertical cross-sectional view of the main part showing the structure of the lower collar 24b provided with the misalignment prevention structure 80 according to the modification, and FIG. 6 (A) is a cross section taken along the line VIA-VIA in FIG. FIG. 6B is a cross-sectional view taken along the line VIB-VIB in FIG. That is, FIG. 6 (A) shows a vertical cross section of the lower eyelid 24b at a portion where the misalignment prevention structure 80 is not provided, and FIG. 6 (B) shows an lower eyelid at a portion where the misalignment prevention structure 80 is provided. The longitudinal section of 24b is shown.

  The misalignment prevention structure 80 is provided between the engagement groove 38 of the metal rod 30 and the engagement piece 40 of the resin rod 32. Hereinafter, a specific configuration example will be described by exemplifying the misalignment prevention structure 80 provided on the lower rod 24b. However, the misalignment prevention structure 80 is engaged with the engagement grooves 38 of the upper rod 24a and the door rod 24c. It can be similarly provided between the pieces 40. The position where the misalignment prevention structure 80 is formed may be the same as the position where the misalignment prevention structure 70 is formed. For example, the misalignment prevention structure 80 is provided near one end in the longitudinal direction of the flanges 24a to 24d. The misregistration prevention structure 80 may be used in combination with the misregistration prevention structure 70 described above, or only one of them may be used.

  As shown in FIG. 6 (A), the opening end of the engagement groove 38 formed in the lower flange portion 30b of the metal rod 30 is a claw-like shape that comes into contact with and locks the tip of the engagement piece 40. A contact piece 38c is provided. The contact piece 38c protrudes from the tip end portion of the wall portion 38b serving as the upper wall of the engagement groove 38 to the inside of the engagement groove 38, and extends in the longitudinal direction of the lower collar portion 30b.

  As shown in FIG. 6B, the misalignment prevention structure 80 has a protruding portion in which a part protrudes toward the inside of the engaging groove 38 in the longitudinal direction of the wall portion 38b that is the upper wall of the engaging groove 38. 82.

  FIG. 7 is an enlarged view of a main part showing the structure of the portion of the lower eyelid 24b provided with the position shift prevention structure 80 shown in FIG. 6, FIG. 7 (A) is a plan view, and FIG. 7 (B). FIG. 7 is a longitudinal sectional view, and FIG. 7C is a front view seen from the indoor side.

  As shown in FIGS. 7A to 7C, the projecting portion 82 is a tool such as a punch from the upper surface side of the wall portion 38b at a position overlapping the contact piece 38c provided in the engaging groove 38. This is a portion in which the wall 38b and the contact piece 38c are projected and deformed into the engaging groove 38 by striking. That is, the protruding portion 82 has a structure in which a part of the contact piece 38 c in the longitudinal direction is further protruded toward the inside of the engaging groove 39. The protruding portion 82 may be formed at a position shifted from the contact piece 38c. However, if the protruding portion 82 is provided at a position offset from the opening edge of the engaging groove 38 to the back side, the protruding portion 82 hinders the insertion of the engaging piece 40 into the engaging groove 38 as much as possible. Since it is suppressed, it is preferable.

  As shown in FIG. 7C, the projecting portion 82 has a mountain shape along the longitudinal direction of the wall portion 38b (lower collar 24b), similar to the projecting portion 72 described above. Specifically, the shape of the projecting portion 82 is inclined so as to gradually project from the inner wall surface of the wall portion 38b toward the inside of the engaging groove 38 in the direction along the longitudinal direction of the wall portion 38b, and after passing through the top portion. In addition, by inclining so as to gradually return from the inside of the engaging groove 38 toward the wall surface of the wall portion 38b, a shape having a ridge line along the longitudinal direction of the wall portion 39b is formed. Thereby, the protrusion part 82 becomes substantially V shape when it sees in the insertion direction of the engagement piece 40 to the engagement groove 38. In addition, the top part of the protrusion part 82 may have a pointed shape, or may have a shape that is flat to some extent or a shape that has a certain degree of roundness.

  The formation position in the longitudinal direction of the lower collar 24b of the protrusion 82 may be the same position as the above-described protrusion 72, for example, from the end E of the lower flange 30b of the metal collar 30 to the summoning side. One or more are formed at the offset positions (see FIGS. 7A and 7C).

  In the casing 24 having such a protrusion 82, when the resin casing 32 is mounted on the metal casing 30, the engaging piece 41 is engaged with the engaging groove 38, and then the engaging piece 41 is engaged with the engaging groove 39. Engage with. At this time, at the portion where the misalignment prevention structure 80 is not provided, the tip of the engagement piece 40 is locked to the contact piece 38c (see FIG. 6A). On the other hand, at the portion where the misalignment prevention structure 80 is provided, the top of the protrusion 82 abuts against the tip of the engagement piece 40 inserted into the engagement groove 38 (see FIG. 6B). .

  As a result, the resin cage 32 is mounted in a state in which the resin cage 32 is secured to the metal cage 30 in the expected direction. At the same time, the top portion of the protruding portion 82 bites into the engaging piece 40, so that the relative displacement in the longitudinal direction between the metal rod 30 and the resin rod 32 is prevented.

  At this time, since the above-described inclined surface 41b is provided on the front surface in the engagement direction of the engagement claw 41a of the engagement piece 41 with the engagement groove 39, the engagement piece 40 is formed into the engagement groove 38. After the engagement, the remaining engagement piece 41 can be inserted into the engagement groove 39 more smoothly and engaged. Moreover, since the inclined surface 40a described above is provided on the surface of the engagement piece 40 on the front side in the engagement direction with the engagement groove 38, the engagement piece 40 is also engaged with the engagement groove 38 provided with the protruding portion 82. The joining piece 40 can be inserted and engaged more smoothly. In the case of this configuration example, if the inclined surface 41b is provided at least on the engagement piece 41 to be engaged later, the metal cage 30 and the resin cage 32 can be smoothly engaged. The inclined surface 40a of the engaging piece 40 to be made may be omitted.

  As described above, the casing 24 according to the present embodiment has the engagement piece 39 extending along the longitudinal direction of the resin casing 32 with respect to the engaging groove 39 (38) extending along the longitudinal direction of the metal casing 30. 41 (40) is engaged so that the resin rod 32 is mounted on the metal rod 30, and the pair of wall portions 39a, 39b (38a, 38b) serving as the side walls of the one engagement groove 39 (38). At least one of the wall portions 39b (38b) has a protruding portion 72 (82) that protrudes from a part in the longitudinal direction toward the inside of the engaging groove 39 (38) and contacts the engaging piece 41 (40). ) And at least one of the opening edges of the other engagement piece 40 (41) and the other engagement groove 38 (39), the engagement groove 38 of the engagement piece 40 (41). An inclined surface 40a (41b) inclined with respect to the direction of engagement with (39) is provided. . Moreover, in the said housing 24, at least one wall part 39b (38b) of a pair of wall part 39a, 39b (38a, 38b) used as the side wall of the engaging groove 39 (38) is provided with wall part 39b ( 38b) is provided with a projecting portion 72 (82) projecting from a part in the longitudinal direction toward the inside of the engaging groove 39 (38), and the engaging groove 39 (provided with the projecting portion 72 (82)). 38), the protrusions 72 (82) are brought into contact with the engagement pieces 41 (40) by engaging the engagement pieces 41 (40) with the resin rods 32 attached to the metal rods 30.

  Therefore, in such a case 24 and the joinery 10 having the shojis 14 and 15 using the case 24, the protrusion 72 (82) provided in the engagement groove 39 (38) is provided with the engagement piece 41 (40). The metal rod 30 and the resin rod 32 are engaged and fixed in a state where the metal rod 30 and the resin rod 32 are engaged and pressed so that the relative displacement of the metal rod 30 and the resin rod 32 in the longitudinal direction is shifted. Is prevented. Thereby, for example, even when the resin cage 32 contracts more than the metal cage 30 due to the influence of the environmental temperature, the resin cage 32 does not shift in the longitudinal direction with respect to the metal cage 30. As a result, the occurrence of rattling between the metal cage 30 and the resin cage 32 can be suppressed, and high product quality can be ensured. In addition, the engagement part which connects the metal cage | basket 30 and the resin cage | basket 32 is 3 sets other than 2 sets of the set of the engagement groove 39 and the engagement piece 41, and the set of the engagement groove 38 and the engagement piece 40, for example, 3 More than one set may be provided.

  In this case, in the case 24 and the joinery 10, it is possible to prevent the resin case 32 from rattling only by providing the protrusions 72 (82) on the metal case 30. This is unnecessary and the increase in cost can be minimized. In addition, since the misalignment prevention structure 70 (80) by the projecting portion 72 (82) is constructed simply by attaching the resin cage 32 to the metal cage 30, there is no reduction in the efficiency of the assembly work.

  Moreover, for example, after engaging one engagement piece 41 and one engagement groove 39 having a large engagement depth (amount) with each other, the other engagement piece 40 and the other engagement groove are first engaged. Since the workability of the assembly procedure is such that the other engaging piece 40 or the other engaging groove 38 to be engaged later is provided with an inclined surface 40a. As a result, the workability of the assembly work is further improved. Of course, after the other engagement piece 40 and the other engagement groove 38 are first engaged, an assembly procedure for engaging one engagement piece 41 and one engagement groove 39 may be adopted. In that case, if the inclined surface 41b is provided in the opening edge part of the one engagement piece 41 or the one engagement groove 39 to be engaged later, the workability of the assembly work is improved.

  Since the protrusion 72 (82) has a mountain shape along the longitudinal direction of the wall 39b (38b), its fracture surface is not exposed toward the opening end of the engagement groove 39 (38). For this reason, when the engaging piece 41 (40) is inserted and engaged with the engaging groove 39 (38), the projecting portion 72 (82) is not subjected to a large load, which affects the assembly work efficiency. Almost never comes out. In particular, since the protruding portion 72 is provided at a position on the back side of the opening end of the engagement groove 39, the load when the engagement piece 41 is inserted into the engagement groove 39 is further reduced.

  By the way, when the protrusion 72 (82) is provided at a position shifted from the corresponding contact piece 39d (38c) in the structure having the contact piece 39d (38c), the protrusion 72 (82) is connected to the engagement piece 41 ( In order to abut against and press the member 40), it is necessary to form the protruding amount of the projecting portion 72 (82) larger than the abutting piece 39d (38c). Therefore, by providing the protruding portion 72 (82) at a position overlapping the contact piece 39d (38c) provided in the engaging groove 39 (38), the protruding portion 72 (82) can be engaged with the engagement piece with a slight protrusion amount. 41 (40) can be surely bitten and can be easily processed.

  It should be noted that the present invention is not limited to the above-described embodiment, and it is needless to say that the present invention can be freely changed without departing from the gist of the present invention.

  For example, in the above-described embodiment, the configuration in which the protruding portion 72 (82) is provided on one wall portion 39b (38b) constituting the engaging groove 39 is illustrated, but the protruding portion 72 (82) is the other wall portion 39a ( 38a), or may be provided on both wall portions 39a, 39b (38a, 38b) depending on the shape of the engaging groove 39 (38) and the engaging piece 41 (40). Of course, the protrusions 72 and 82 may be used in combination.

  In the above-described embodiment, the configuration in which the two engagement pieces 40 and 41 are engaged with the two engagement grooves 38 and 39 is illustrated. However, the two engagements of the metal rod 30 with which the engagement pieces 40 and 41 are engaged are illustrated. At least one of the joint portions may be an engagement groove, and the other portion may not have a groove shape as long as the engagement piece can be engaged with the engagement piece. Further, the number of engaging portions may be three or more.
