Description

The present invention relates to a synthetic resin frame member attached along an edge of a panel.

For example, it has been proposed to use a synthetic resin mold for the frame member of the window panel constituting the sliding door.

JP 2007-138614 A JP 2011-236736 A

According to the above-mentioned Patent Document 1, in order to improve the impact resistance of the window frame and various properties required for the fitting facing the outdoor, there is a technique for forming the surface layer portion with the selected synthetic resin material. Proposed. However, when a panel frame member is provided by a synthetic resin mold, there are various structural problems apart from the problem of the synthetic resin material itself as described in Patent Document 1.

By the way, according to the said patent document 2, in order to improve soundproofing and heat insulation regarding the glass window of a general house, the inner window apparatus provided in the indoor side of the existing window is proposed. However, since the technology proposed in Patent Document 2 is a full-fledged double sash device in which an aluminum inner window device is similarly provided for an aluminum outer window device, the cost is high. As a matter of course, a general amateur who is not a craftsman cannot easily carry out construction work as DIY.

Therefore, the present inventors have proposed Japanese Patent Application Nos. 2012-233462 and 2013-117721 as prior applications in order to provide a frame member made of a synthetic resin mold material that can be attached to the periphery of the panel. .

The frame member proposed by the prior application (hereinafter referred to as “prior art frame member”) is made of a synthetic resin mold material in which a groove portion for inserting an edge portion of the panel is formed by a bottom wall and both side walls, and is a rectangular panel. A frame panel body is formed by attaching to the peripheral edge of the frame, engaging lips projecting from the both side walls toward the inside of the groove, and the frame member forming the groove is rigid. The engaging lip is integrally formed with the frame member with a soft synthetic resin.

Therefore, the frame member simply inserts the edge portion of the panel into the groove portion, and the engaging lips facing each other are deformed to closely adhere to both sides of the edge portion, so that the edge portion of the panel is suitably centered inside the groove portion. It is possible to hold and fix the frame member and the panel at a desired position, and a frame panel body in which a synthetic resin frame member is provided around the periphery of the panel is easily formed without the need for a tool or the like. There is an effect that can be.

However, as a result of further intensive studies, the present inventors have found that the prior art frame member has the following problems to be further improved.

For example, when selecting a material for the engaging lip, when using a soft synthetic resin having a small hardness or elastic rebound rate, the contact area of the engaging lip with the edge is increased in order to increase the holding force of the edge of the panel. It is necessary to form it to be large. However, since the frame member of the prior art is formed so that the pair of engaging lips face each other from both side walls, the protruding length of the engaging lip cannot be formed long. For this reason, when the retaining force of the engaging lip is weak, the edge of the panel inserted into the groove of the frame member is pulled out relatively easily, so that the edge of the panel is thickened, etc. There is a problem such as having to stick. This is the first problem of the present invention.

Contrary to the above, when selecting a material for the anchoring lip, when using a soft synthetic resin having a high hardness or elastic rebound rate, it is possible to increase the holding force against the edge of the panel. When inserting into a groove part, since a strong insertion force is calculated | required, a user will be forced to do severe work. In particular, the frame member of the prior art projects a pair of engaging lips from both side walls to face each other, and when the edge portion of the panel is inserted into the groove portion, the edge portion simultaneously contacts the pair of engaging lips. Therefore, a strong insertion force is required to get over the edge while simultaneously elastically deforming the pair of engaging lips. For this reason, when the holding force of the engaging lip is strong, there is a problem that a thin panel must be selected. This is the second problem of the present invention.

Furthermore, the prior art frame members have several problems to be solved.

The present invention provides a frame member for a synthetic resin panel that solves the above-mentioned problems, and as a means thereof, a synthetic resin in which a groove portion for inserting an edge portion of the panel is formed by a bottom wall and both side walls is provided. A frame member made of a mold material and configured to be attached to the peripheral edge of a rectangular panel, and a locking lip projecting from the both side walls toward the inside of the groove portion to form the groove portion In the structure in which the engaging lip is integrally formed with the frame member by using a soft synthetic resin, and the first engaging lip protruding from one first side wall in the depth direction of the groove portion and the other The second engaging lip protruding from the second side wall is arranged in a state of being displaced from each other.

In a preferred embodiment of the present invention, the engaging lip protruding from at least one of the first side wall and the second side wall is constituted by a plurality of engaging lips arranged at predetermined intervals in the depth direction of the groove. The engaging lip protruding from the other side wall is arranged so as to face the interval between the plurality of engaging lips.

In a further preferred embodiment of the present invention, the first engaging lip and the second engaging lip are constituted by a plurality of engaging lips arranged at predetermined intervals in the depth direction of the groove portion. The plurality of engaging lips constituting the attaching lip and the plurality of engaging lips constituting the second engaging lip are alternately arranged in the depth direction of the groove portion.

According to the present invention, the first engaging lip 10a protruding from the first side wall 7a and the second engaging lip 10b protruding from the second side wall 7b are opposed to each other in a butting manner. In addition, since the grooves 6 are alternately arranged in the depth direction, any of the engaging lips 10a and 10b can be formed to have a long length L from the base end portion to the tip end portion. Since it becomes possible to increase the contact area of the engaging lips 10a and 10b that are elastically in close contact with the two edge portions 2a, the holding force of the panel 2 is ensured and the first problem described above is solved. be able to.

At this time, according to the above-described configuration of alternating arrangement, the lengths L of the engaging lips 10a and 10b are set to the lengths L1 and L2 close to the center line C of the groove 6 and the center line C, as necessary. Therefore, the degree of freedom in design can be greatly improved. However, in the present invention, it is not a requirement to extend the length of the engaging lip to the center line C. For example, the engaging lips 10a and 10b deformed along the edge 2a have base end portions 10y. The tip portion 10x may be bent to have an L-shaped cross section, and the tip portion 10x may be formed to a length that allows the surface contact portion M to be formed on the side surface of the edge 2a. Thereby, when the panel 2 is forcibly moved in the drawing direction R, the surface contact portion M follows in a state of being in close contact with the surface of the edge portion 2a, and the bent distal end portion 10x and the proximal end portion 10y are overlapped with each other. Since it is deformed, the holding state is maintained while increasing the adhesive force until the edge 2a has passed through the surface contact portion M, so that the panel 2 can be made difficult to pull out.

Moreover, according to the present invention, since the first engaging lip 10a and the second engaging lip 10b are alternately arranged in the depth direction of the groove portion 6, the edge portion 2a of the panel 2 is inserted into the groove portion 6. At this time, the edge portion 2a does not abut against the two engaging lips at the same time, and the engaging lips 10a and 10b are alternately deformed so that the force required for inserting the panel 2 can be reduced. The second problem described above can be solved.

And according to this invention, even if it is the panel 2 from which the thickness T is somewhat different as a result of solving both the subject of the above-mentioned 1st subject and the 2nd subject, the insertion with respect to the groove part 6 is easy. In addition, the holding force after insertion and the pull-out resistance are excellent, and there is an effect that two anti-contradictory functions can be satisfied at the same time.

[First Embodiment]
4 and 5 show a first embodiment of the present invention. The frame member 1 includes a frame main body 8 including both side walls 7a and 7b of the groove portion 6, and a pair of seal lips 9 that are located at the opening edge of the groove portion 6 and project opposite to each other from both sides of the both side walls 7a and 7b. , 9 and engaging lips 10a, 10b protruding from the side walls 7a, 7b, located inside the groove 6 spaced from the opening edge of the groove 6. In addition, the frame member 1 is comprised by the shaping | molding material by the extrusion molding of a synthetic resin, and is continued as the same cross-sectional shape with respect to a longitudinal direction.

Both side walls 7a, 7b of the frame body 7 are provided with extension walls 12, 12 extending beyond the bottom wall 11 of the groove 6 and with outer bottom walls 13 connecting the extension ends of the extension walls 12, 12. The bottom wall 11, the extension walls 12, 12 and the outer bottom wall 13 constitute a reinforcing section 14 having a cylindrical cross section. Furthermore, ribs 15 and 15 projecting from the side walls 7a and 7b so as to face each other are provided inside the groove portion 6. In the illustrated example, the ribs 15 and 15 are provided between the engaging lips 10a and 10b and the bottom wall 11, but any ribs 15 and 15 can be used as long as they do not interfere with the engaging lips 10a and 10b. Can be provided in position. Further, the pair of ribs 15, 15 do not have to face each other in abutting manner, and may be provided with their positions shifted in the depth direction of the groove 6. Thereby, even when the frame member 1 is formed in a long shape, the reinforcing portion 14 prevents deformation and distortion in the torsional direction and the like, and the ribs 15 and 15 generate distortion on both side walls 7a and 7b. Is prevented. As a result, the thickness of each part of the frame member 1 can be reduced, contributing to weight reduction and cost reduction.

The pair of seal lips 9, 9 are formed in a thin plate shape that protrudes opposite to each other from the top surfaces of the side walls 7 a, 7 b that form the opening edge of the groove 6, and the center line of the groove 6 It is formed so as to be line-symmetric with respect to C, and holds a substantially horizontal posture as the original posture.

The engaging lip 10 protrudes from the first engaging lip 10a protruding from the first side wall 7a and the second side wall 7b when one of the side walls is the first side wall 7a and the other is the second side wall 7b. The second engaging lip 10b is configured, and the first engaging lip 10a and the second engaging lip 10b are arranged so as to be displaced from each other with respect to the depth direction of the groove 6. Accordingly, the first engaging lip 10a and the second engaging lip 10b do not face each other in a butted manner.

The engaging lips 10a and 10b are formed in a thin plate shape projecting from the inner side surfaces of the side walls 7a and 7b, and are formed so as to gradually reduce the thickness from the base end portion toward the tip end portion. In the case of the embodiment, the inclination posture that is inclined at an angle θ from the direction orthogonal to the panel 2 toward the insertion direction F of the panel is held as the original posture.

The frame member 1 is formed by two-color extrusion molding using a hard synthetic resin (for example, hard PVC) and a soft synthetic resin (for example, soft PVC), and includes the side walls 7a and 7b, the reinforcing portion 14, and the ribs 15 and 15. The frame body 8 is molded from a hard synthetic resin, and the sealing lips 9, 9 and the engaging lips 10a, 10b are molded from a soft synthetic resin. In the present invention, the hard synthetic resin means a synthetic resin having a certain degree of flexibility, and the soft synthetic resin means an elastically deformable synthetic resin such as an elastomer. At this time, the seal lips 9 and 9 and the engaging lips 10a and 10b may be formed of a soft synthetic resin of the same material. However, by combining soft synthetic resins of different materials, the seal lips 9 and 9 are relatively Preferably, the engaging lips 10a and 10b are formed of a soft synthetic resin having a relatively high elastic hardness or elastic restitution rate.

In the case of the first embodiment, the first engaging lip 10a includes a plurality of engaging lips 10a (upper and lower two in the case of the figure) arranged vertically with a predetermined interval S in the depth direction of the groove 6; In contrast, the second engaging lip 10b is composed of a single engaging lip 10b, and the second engaging lip 10b is located within the interval S between the first engaging lips 10a, 10a. It is arranged to face. In the case of the illustrated embodiment, the first position P1, the second position P2, and the third position P3 are set in order from the opening of the groove 6 toward the bottom wall 11, and the upper side from the first position P1 is set. The first engaging lip 10a protrudes, the second engaging lip 10b protrudes from the second position P2, and the lower first engaging lip 10a protrudes from the third position P3.

Therefore, the first engaging lip 10a and the second engaging lip 10b do not face each other in a butting manner and are alternately arranged in the depth direction of the groove portion 6, so that any of the engaging lips The lips 10a and 10b can also be formed to have a long length L1 from the base end portion to the tip end portion.

For this reason, the length L1 of the engaging lips 10a and 10b is configured so that the tips of the engaging lips 10a and 10b reach the center line C of the groove portion 6 in the example shown in the figure, but the tip is the center line C. It is also possible to form it long so as to exceed.

Therefore, as shown in FIG. 5, when the edge 2a of the panel 2 is inserted into the groove 6 between the seal lips 9 and 9, the seal lips 9 and 9 are deformed downward, thereby allowing the entry of the edge 2a. Then, the end face of the edge portion 2a enters while deforming the engaging lips 10a and 10b alternately in the order of P1, P2 and P3, and then comes into contact with the bottom wall 11. Therefore, the edge portion 2a of the panel 2 does not deform the two engaging lips at the same time, and enters the groove portion 6 while deforming the engaging lips one by one with a time difference in the entering direction. The force required to insert 2 can be reduced.

In the state where the insertion of the panel 2 is completed, the engaging lips 10a and 10b formed long as described above are bent toward the insertion direction with the long extending tip portions, and are elastically restored over a wide contact area. Since it is closer to the force, both side surfaces of the edge 2a of the panel 2 are strongly held. In addition, the panel 2 is held so that it is difficult to forcefully move the panel 2 in the drawing direction R. The operation of this point will be described later with reference to FIG.

As described above, the frame member 1 according to the first embodiment is optimally configured to hold the edge 2a of the panel 2 so that it is easy to insert and difficult to pull out by inclining the engaging lips 10a and 10b at an angle θ. Of course, the present invention is not limited to this.

[Second Embodiment]
6 and 7 show a second embodiment of the present invention. Since the structure regarding the frame main body 8 molded by the hard synthetic resin is the same as that of the first embodiment, the above description of the first embodiment is cited and detailed description thereof is omitted.

In the case of the second embodiment, the thin plate-like seal lips 9 and 9 projecting in opposition to each other from the top surfaces of the side walls 7a and 7b forming the opening edge of the groove 6 have an interval between the opposed tips. It is formed to be narrower than in the case of the first embodiment. That is, by forming the seal lips 9 and 9 longer, the lengths of the engaging lips 10a and 10b are formed slightly shorter than in the first embodiment.

The engaging lips 10a and 10b are formed in a thin plate shape protruding from the inner surfaces of the side walls 7a and 7b, and are formed so as to gradually reduce the thickness from the base end portion toward the tip end portion. The first engaging lip 10a protruding from the first side wall 7a has a plurality of engaging lips (upper and lower two in the case of the figure) arranged vertically with a predetermined interval S in the depth direction of the groove 6. Similarly, a plurality of second engaging lips 10b that protrude from the second side wall 7b are vertically arranged with a predetermined interval S in the depth direction of the groove 6 (in the example of the figure). In this case, it is constituted by two upper and lower engaging lips 10b and 10b.

The plurality of engagement lips 10a and 10a constituting the first engagement lip 10a and the plurality of engagement lips 10b and 10b constituting the second engagement lip 10b are alternately arranged in the depth direction of the groove portion 6. Has been. In the case of the illustrated embodiment, the first position P1, the second position P2, the third position P3, and the fourth position P4 are set in order from the opening of the groove 6 toward the bottom wall 11, The upper second engaging lip 10b protrudes from the first position P1, the upper first engaging lip 10a protrudes from the second position P2, and the lower second engaging lip from the third position P3. A lip 10b is protruded, and a lower first engaging lip 10a is protruded from the fourth position P4.

Therefore, since the first engaging lip 10a and the second engaging lip 10b are not opposed to each other in a butting manner and are alternately arranged in the depth direction of the groove portion 6, any of the engaging lips The lips 10a and 10b can also be formed to have a long length L2 from the base end portion to the tip end portion. For this reason, the length L2 of the engaging lips 10a and 10b is configured so that the tips of the engaging lips 10a and 10b reach the center line C of the groove 6 in the illustrated example. It is also possible to form it long so as to exceed.

In the case of the second embodiment, the engaging lips 10a and 10b hold the horizontal posture orthogonal to the panel 2 as the original posture, and are not inclined as in the first embodiment.

Therefore, as shown in FIG. 7, when the edge portion 2a of the panel 2 is inserted into the groove portion 6 between the seal lips 9 and 9, the seal lips 9 and 9 are deformed downward, thereby allowing the edge portion 2a to enter. Then, the end face of the edge portion 2a enters while deforming the engaging lips 10a, 10b alternately in the order of P1, P2, P3, P4, and then comes into contact with the bottom wall 11. Therefore, the edge portion 2a of the panel 2 does not deform the two engaging lips at the same time, and enters the groove portion 6 while deforming the engaging lips one by one with a time difference in the entering direction. The force required to insert 2 can be reduced.

In the state where the insertion of the panel 2 is completed, the engaging lips 10a and 10b formed long as described above are bent toward the insertion direction with the long extending tip portions, and are elastically restored over a wide contact area. Since it is closer to the force, both side surfaces of the edge 2a of the panel 2 are strongly held. In addition, the panel 2 is held so that it is difficult to forcefully move the panel 2 in the drawing direction R. The operation of this point will be described later with reference to FIG.

[Third Embodiment]
8 and 9 show a third embodiment of the present invention. The configuration related to the frame body 8 and the seal lips 9, 9 is the same as that of the second embodiment, and the configuration of the engaging lips 10a, 10b is the same as that of the second embodiment except for the length. The above description of the second embodiment is incorporated and detailed description is omitted.

In the case of the third embodiment, a plurality of upper and lower first engaging lips 10a and 10a protruding from the first side wall 7a and a plurality of upper and lower second engaging lips 10b and 10b protruding from the second side wall 7b are: The tip is formed to have a length L3 that does not reach the center line C of the groove 6.

Therefore, as shown in FIG. 9, when the edge portion 2a of the panel 2 is inserted into the groove portion 6 between the seal lips 9 and 9, the seal lips 9 and 9 are deformed downward, thereby allowing the edge portion 2a to enter. Then, the end face of the edge portion 2a enters while deforming the engaging lips 10a, 10b alternately in the order of P1, P2, P3, P4, and then comes into contact with the bottom wall 11. Therefore, the edge portion 2a of the panel 2 does not deform the two engaging lips at the same time, and enters the groove portion 6 while deforming the engaging lips one by one with a time difference in the entering direction. The force required to insert 2 can be reduced.

In the state where the insertion of the panel 2 is completed, the engaging lips 10a and 10b formed long as described above are bent toward the insertion direction with the long extending tip portions, and are elastically restored over a wide contact area. Since it is closer to the force, both side surfaces of the edge 2a of the panel 2 are strongly held. In addition, the panel 2 is held so that it is difficult to forcefully move the panel 2 in the drawing direction R. The operation of this point will be described later with reference to FIG.

[Action on panel pull-out direction]
FIG. 10 shows the operation of the frame member of the prior art in FIGS. 10 (A) and 10 (B), and the operation of the present invention is shown in FIGS. 10 (C) and 10 (D).

The engaging lip 16 provided on the frame member of the prior art is protruded from both side walls 17 of the frame main body so as to face each other, and is formed to a length that can hold the edge 2a of the panel. . Therefore, when the edge portion 2a of the panel is inserted into the groove portion, the engaging lip 16 is curved and deformed from the original shape indicated by the chain line in FIG. 10A to the arc shape indicated by the solid line, and holds the edge portion 2a. At this time, the tip of the engaging lip 16 is in line contact with the surface of the edge 2a. Therefore, as shown in FIG. 10B, when the panel is moved in the pulling direction by R1, as shown by the chain line, the tip of the engaging lip 16 follows the edge 2a and moves by R2. However, when the attitude of the engaging lip 16 becomes orthogonal to the edge portion 2a by this follow-up movement, the tip end is then deformed so as to face upward as indicated by the solid line. For this reason, when the edge part 2a of a panel moves only R1, there exists a problem that the front-end | tip of the engaging lip 16 cannot oppose the extraction direction of the edge part 2a.

On the other hand, the engaging lip 10 provided on the frame member of the present invention is disposed in a state of being displaced with respect to the depth direction of the groove portion from both side walls 7 of the frame body, and has the length described in the above embodiment. It is formed long like L1, L2, and L3. Therefore, when the edge portion 2a of the panel is inserted into the groove portion, the engaging lip 10 is deformed from the original shape indicated by the chain line in FIG. 10C as indicated by the solid line, and holds the edge portion 2a. Thereby, the engaging lip 10 is bent so that the base end portion 10y and the tip end portion 10x have an L-shaped cross section, and the tip end portion 10x forms a surface contact portion M on the side surface of the edge portion 2a. Therefore, as shown in FIG. 10D, when the panel is moved in the pulling direction by R1, as shown by a chain line, the tip of the engaging lip 16 also follows the edge 2a and moves by R2. At this time, the bent distal end portion 10x and the proximal end portion 10y are deformed in the direction in which they are overlapped with each other, so that not only the adhesion to the edge 2a is increased, but the distal end portion 10x is still held downward. Therefore, it opposes the pulling direction of the edge 2a. Thereby, the engaging lip 10 maintains the holding state while increasing the contact force until the edge portion 2a has passed through the surface contact portion M, making it difficult to pull out the panel 2.
