Description

  The present invention relates to a fixture for mounting a decorative molding material on a plate member such as a door surface.

Generally, a decorative molding material is attached to a surface material such as an entrance door to give the door a high-class feeling. In Patent Document 1 below, a pair of insertion pieces 11 that elastically deform inward due to contact with the hole wall of the mounting hole when inserted into the mounting hole 1 provided in the door surface material at both ends of the bent base 10. Forming a V-shaped bent piece portion 12 engageable with the mounting hole at the distal end portion of each insertion piece, engaging the door surface material at the distal end of each bent piece portion, Engagement piece portions 13 for positioning the bent piece portion 12 are provided at positions opposite to the hole walls of the metal plate, and each of the engagement piece portions is curved to engage with the flange inner side edge portion of the molding material. There is disclosed a fixture in which a portion 13a is provided and a retaining member 17 is formed on both ends of the curved portion. When the molding material is attached, the retaining member comes to a position facing the inner surface of the flange of the molding material to prevent the molding material from coming off.
JP 2000-74020 A

However, the above-mentioned retaining prevention piece is applied to a molding material having a flange having a specific thickness, and is not configured to be applied to a molding material having a flange having various thicknesses. Even if the stopper piece is applied to prevent the molding material fixture from coming off the door surface material, it cannot be conceived until it is applied to a plate member having a plurality of thicknesses. Since the molding material is made of extruded aluminum, it is easy to unify the thickness of the flange part held by the molding material fixture, but the thickness of the surface material of the door is the performance required for the door. Therefore, if there is a molding material fixture that can be used for door surface materials with multiple thicknesses, the molding material fixtures can be unified and the type can be unified or the type can be changed. Can be reduced.
Therefore, an object to be solved is to provide a molding material fixture that can be applied to a plurality of types of plate members having different thicknesses and that can be prevented from coming out.

In the invention which concerns on Claim 1, it expands in the position regulated by the regulation part which regulates the amount inserted in the hole provided in the board member, and faces the back of the board member to the board member. A molding including a slip-out preventing portion having a locking piece that can be prevented from slipping out, a body portion that presses and holds the wall surface of the hole by elastic deformation, and a molding material mounting portion for mounting the molding material. The pull-out prevention part has a plurality of locking pieces having different distances from the restriction part and the tip of the locking piece, and is not pulled out from a plurality of types of plate members having different plate thicknesses. In the plurality of locking pieces, the tip end portions of the locking pieces other than the locking piece having the longest distance from the restricting portion to the locking piece tip are bent inward. providing molding material fittings, characterized in that there.
As the molding material fitting, as long as it is an elastic body, it may be made of synthetic resin in addition to the metal fittings.

According to a second aspect of the present invention, the plurality of locking pieces provide the molding material fixture according to the first aspect , wherein the respective locking pieces are adjacently formed in a stepped shape.

According to a third aspect of the present invention, the flange portion of the molding material defines a slot, and the mounting portion for molding material is a pair of moldings whose distal ends are bent inward and press the hole wall of the slot. Each molding material holding locking piece is cut and raised from the main body, and is elastically deformed independently of elastic deformation of the main body. The molding material fixture according to claim 1 or 2, which presses the hole wall of the hole.
According to a fourth aspect of the present invention, the molding member mounting portion further includes a molding member locking piece whose tip is located at a position longer than the distance from the regulation portion to the tip of the molding member holding locking piece. 4. The molding material mounting tool according to claim 3 , wherein the molding material locking piece expands when the molding material is mounted and faces the inner surface of the flange to prevent the molding material from coming out of the molding material.

According to the first aspect of the present invention, the molding material fixture can be inserted into the hole provided in the plate member to a predetermined position and stopped by the regulation action of the regulation part. Since the stop piece faces the back surface of the plate member, the fixture does not come out from the hole of the plate member to the insertion side (surface side). Eventually, the molding material fixture cannot be pulled forward or backward by the restricting portion and any of the locking pieces, and can hold the hole wall by being elastically deformed. Moreover, it can be mounted and applied to a plurality of types of plate members with one type of molding material fixture. Further, the molding material can be mounted by the molding material mounting portion. In addition, since the tip of the locking piece other than the locking piece having the longest distance from the restricting portion is bent inward, i.e., it is a reverse taper where the expected dimension of the tip in the insertion direction is thick, When the reverse taper bent portion of the locking piece is attached to the plate member having a thickness that presses the hole wall of the plate member, a force in the insertion direction is generated, and rattling is prevented and holding force is reduced. Increase. That is, if there is no reverse taper bent portion and only a tapered taper portion, a force for pushing the fixture to the surface side of the plate member is generated, and this force is a force in a direction in which the regulating portion is separated from the plate member surface. As a result, rattling occurs in the fixture, but this can be prevented by the reverse taper bend.

According to the second aspect of the present invention , since the plurality of locking pieces are formed in a step shape adjacent to each other, the manufacturing becomes easy.

In claim 3 , since the molding piece for holding the molding material is cut and raised from the main body, even if the diameter of the main body is reduced by mounting the plate member in the hole, The wall of the molding material slot can be pressed independently without being affected by the reduced diameter. Therefore, the molding material can be reliably held regardless of the hole of the plate member. In addition, since the bent portion on the front end side of the holding piece for holding the molding material that presses the hole wall of the groove hole is bent inward, it is reversely tapered for mounting the molding material. A force for pressing the material against the plate member is generated, and the molding material can be held without looseness.
According to the fourth aspect of the present invention , since the molding piece can be locked to the inner surface of the flange of the molding material, the molding material can be reliably prevented from coming out.

  FIG. 1 is a developed view of a molding material fixture 30 according to the present invention, which is a metal plate member 30 ′ obtained by punching a metal plate material having elasticity into a predetermined shape. This is a vertically symmetrical shape with respect to the center line CL in the figure. The plate member is bent along a plurality of lines parallel to the center line to form a molding material fixture 30 whose front view is shown in FIG. FIG. 3 is a side view taken along the line of sight C of FIG. The molding material fixture according to the present invention may be manufactured to have elasticity by injection molding a synthetic resin without using such a metal plate material.

  The front side portion 30A and the rear side portion 30B of the molding material fixture 30 in FIG. 2 have a restriction portion 30K that is a shoulder portion as a boundary. That is, the rear side portion 30B is wider than the front side portion by the horizontal dimension in FIG. 2 of the right and left restricting portions 30K. On the other hand, for example, an elongated rectangular hole 10H is formed in a plate member such as a surface decorative board of the door. The longitudinal dimension of the hole is larger than the lateral dimension of the front side portion 30A, and the left and right sides of the rear side portion 30B. If it is set to a value smaller than the directional dimension and close to the horizontal dimension of the front side portion 30A, the mounting may be stable. When the molding material fitting 30 is inserted into the rectangular hole in the front side portion 30A, the regulation portion 30K abuts on the plate member surface and the insertion is regulated. Even if it is not a rectangular hole but a round hole, the front side portion 30A can be curved to cope with it.

  On the other hand, the molding material fixture 30 clearly appears in the plate member of FIG. 1, but generally H-shaped holes KK are formed symmetrically with respect to the center line CL. Two sets of stair-like locking pieces, which are stepped with two locking pieces, are provided at opposing positions. That is, one is a stepped locking piece portion having two adjacent plate member locking pieces T1, T2 provided on the front side far from the center line CL. The other is a stepped locking piece portion provided on the side close to the center line and having the adjacent molding member holding locking piece U1 and molding material locking piece U2. The long locking pieces T1 and U1 and the short locking pieces T2 and U2 face each other. In order to make it easier for a long locking piece to bend independently of an adjacent short locking piece, splits K1 and K2 are provided at the boundary of each locking piece of each stepped locking piece.

  The shape and operation of each part will be described with reference to FIGS. In general, at the time of insertion, the substantially U-shaped overall shape shown in FIG. First, the shape and operation of the front side portion 30A of the attachment main body other than each stepped locking piece will be described. In FIG. 3, the front portion 30a of the front side portion 30A has a tapered shape in which the front portions 30a on both the left and right sides of the center line approach each other, and the plate member can be easily inserted into the hole. On the other hand, the rear region portion (a holding portion described later) 30H has a reverse taper shape. Due to this reverse taper, when the molding material fixture 30 is inserted into the hole, a force to be drawn in the insertion direction is generated, and the regulating portion 30K is retracted so as to contact the surface of the plate member, thereby preventing rattling in the plate thickness direction. However, it is mounted and held.

  Next, the shape and action of the stepped locking piece portion having the plate member locking pieces T1, T2 will be described. The pair of plate member locking pieces T2 having a long distance L2 from the restricting portion 30K to the locking piece tip T2E and a short leg length are tapered toward the front of insertion, thereby facilitating insertion. On the other hand, when the plate member is thick, the pair of plate member locking pieces T1 having a shorter leg length with the shorter distance L1 is a portion where the locking piece base side is inserted through the hole of the plate member. The tip T1E side region) is formed to be bent inward from each other and has a reverse taper with respect to the insertion direction, and the other regions are tapered. The meaning of the reverse taper portion is that when it is attached to the thicker plate member (in the case of FIG. 4 instead of FIG. 5), if this reverse taper portion is not present, that is, if it remains in a tapered shape, the molding material is attached. A force that pushes the tool back to the surface side of the plate member acts and rattling occurs, but a force that pulls in the insertion direction is generated by the reverse taper portion, and the restriction portion 30K is retracted so as to contact the surface of the plate member. The rattling can be prevented, and the holding force is increased with respect to the pressing force to the hole wall.

  When configured as the molding material attachment 30, each distance from the restricting portion 30K to the tip T1E, T2E, U1E, U2E of each of the pair of locking pieces T1, T2, U1, U2 is a predetermined L1. , L2, M1, and M2. For this reason, when the molding material fixture 30 is inserted into the rectangular hole 10H of the plate member 10 having a predetermined thickness shown in FIG. That is, the left and right widths (expected dimensions) in FIG. 3 showing the normal time are rectangular in the front side portion 30A of the main body portion of the molding material fixture 30 at least in the region of the holding portion 30H facing the hole wall when the hole is inserted. It is larger than the narrow width of the hole. Further, the left and right widths (probable dimensions) of the regions on the front ends T1E and T2E of the stepped locking pieces having the plate member locking pieces T1 and T2 are also larger than the narrow width of the rectangular holes.

  Accordingly, the expected size of these regions is narrowed when inserted into the rectangular hole, but when the region comes out from the rectangular hole to the back side, it becomes elastically larger than the narrow width of the hole. That is, the short plate member locking piece T2 is released from the hole to the back surface side of the plate member and becomes free, and its tip T2E spreads left and right by the elastic action and spreads close to the back surface of the plate member 10. For this reason, the molding material fixture 30 is prevented from coming off in the direction opposite to the insertion direction. That is, the tip T2E functions as a slip-out preventing part. On the other hand, disconnection in the front direction is prevented by the presence of the restricting portion 30K.

  As described above, the expected size of the region facing the hole wall when the hole of the holding portion 30H is inserted is larger than the narrow width of the rectangular hole. It is inserted while having a reduced diameter with elasticity. The holding part 30H faces the hole wall at the inserted position in this way, and the holding part 30H having elasticity in the thickness direction presses the edge of the hole wall of the rectangular hole 10H. At this time, since the holding portion has a reverse taper, a force to be drawn in the insertion direction is generated, whereby the molding material fixture can be stably held while preventing rattling. This pressing and holding can also be regarded as a kind of action for preventing slipping out. Further, in this case, in the pair of long plate member locking pieces T1, reverse taper regions bent inward near each other press the hole wall edge of the rectangular hole 10H. Accordingly, the holding force of the molding material fixture to the plate member is further improved, and the force for pulling the molding material fixture in the insertion direction acts to assist the action of preventing the molding material fixture from rattling.

  In this way, the molding material 20 is pushed in and attached to the rear side portion 30B of the molding material fixture 30 which is stable through the slot 20H on the back surface side. This molding material has a flange 20F having a predetermined thickness. The shape and the like of the rear side part 30B will be described. The left and right width (expected dimension) in FIG. 3 showing the normal state of the molding material fixture 30 is a tapered shape in the rear side portion 30B of the main body portion of the molding material fixture 30 in the relative insertion direction with respect to the molding material. The tip width is smaller than the slot width, and the molding material can be easily inserted into the slot 20H. In the insertion direction, the slot facing portion 30H 'which is a rear region is reversely tapered. In this example, the slot facing portion 30H 'is smaller than the width of the slot 20H. Therefore, when the molding material 20 is inserted, the slot facing portion 30H ′ does not elastically reduce its diameter, and does not affect the plate member locking pieces T1 and T2 and the holding portion 30H, which are the slip-out preventing portions for the plate member. Therefore, the plate member can be securely held and locked.

  Further, the shape and action of the step-like locking piece portion having the molding material holding locking piece U1 and the molding material locking piece U2 will be described. The pair of molding pieces U2 having a shorter leg length with a longer distance M2 from the restricting portion 30K to the tip U2E of the molding piece U2E has a taper shape that is tapered forward in the relative insertion direction. become. On the other hand, the pair of long holding pieces U1 for holding the molding material with the shorter distance M1 has the locking piece tip portions (the region on the tip U1E side) bent inwardly with respect to the relative insertion direction (when inserted). ) Inverted taper, and other regions are tapered. Moreover, the prospective dimension of each front-end | tip U1E and U2E side area | region of the step-like locking piece part for molding materials which has locking piece U1, U2 is larger than the width | variety of a slot.

  Therefore, the molding piece holding locking piece U1 and the molding piece locking piece U2 are inserted while their expected dimensions are reduced, and the short locking piece U2 comes out of the slot 20H and elastically expands. The tip U2E faces the inner surface of the flange 20F. For this reason, the molding material is prevented from coming out after being mounted. The long locking piece U1 has a reverse taper region bent inward (near in the prospective dimension direction) near the tip thereof and presses the edge of the hole wall of the slot 20H to obtain a holding force for the molding material. The force that pulls the molding material in the insertion direction acts to prevent the molding material from rattling. Since this long locking piece U1 is cut and raised from the body part (30H, 30H ′, etc.) of the molding material fixture, it is hardly affected by the diameter reduction of the holding part 30H, and is substantially independent of the slot. Since the 20H hole wall edge can be pressed, the design of the dimension setting and the like becomes easy, and a stable holding force can be obtained.

  Unlike the above example, the groove hole facing portion 30H 'of the molding material mounting body main body may have a size configuration in which the edge of the hole wall of the groove 20H is pressed. In this case, the tip portion 30b has a tapered shape, facilitating insertion of the molding material into the slot, and the expected size of the base portion region of the tip portion 30b and the tip portion region of the slot facing portion 30H ′ is elastic. The diameter is reduced and inserted. Further, since the groove facing portion 30H 'has an inversely tapered shape, when the molding material is inserted, a force to be drawn in the insertion direction is generated, and play of the molding material in the thickness direction of the flange 20F can be prevented.

  FIG. 5 is a diagram in which the same molding material 20 is attached to a plate member 10 ′ having a thin plate thickness by a predetermined amount instead of the plate member 10 of FIG. In this case, the plate member locking piece T1 having the longer leg length also slips out from the rectangular hole 30H to the back side, and is elastically expanded, and is not subjected to a pressing force from the hole wall. That is, it is in a spread state in a normal state where it is not inserted, and since the plate member 10 'has a predetermined thickness, the tip T1E faces the back surface of the plate member. Therefore, the molding material fixture 30 is prevented from coming out in the direction of the plate member surface side, and there is little back and forth play. The holding part 30H presses and holds the edge of the hole wall, and the holding part has a reverse taper to prevent rattling, etc., as in the case of the thick plate member 10 in FIG. It is.

  In the above example, both the locking piece on the plate member side and the locking piece on the molding material side are formed in a staircase shape in which the long locking piece and the short locking piece are adjacent to each other. It may be formed. In addition, there are two types of locking pieces, long and short, but three or more types of locking pieces with different distances from the restricting portion 30K to each tip are provided, and three or more types with different plate thickness or flange thickness. It can also be configured to be applicable to the plate member or molding material.

  As described above, in Patent Document 1, the curved portion 13a of the engaging piece portion 13 connected to the bent piece portion 12 engageable with the mounting hole provided in the plate member is the flange inner surface side edge portion of the molding material. Therefore, the holding part for the plate member of the molding material fixture and the holding part for the molding material cannot be elastically deformed independently and are related to each other. Therefore, even if the molding material fixture can be sufficiently held with respect to the plate member, if the molding material is held later, there is a risk that the holding with respect to the plate member may loosen, and the holding cannot be surely performed, which is inconvenient. .

In view of this, the following inventions can be considered based on the idea of allowing the holding pressure to the hole wall of the plate member and the holding pressure to the groove hole of the molding material to be set independently of each other.
A plate member mounting portion having a main body portion which is inserted into a hole provided in the plate member and presses and holds the hole wall of the hole, and a molding material in which the flange portion defines a slot is mounted. A molding material fixture comprising a molding material mounting portion, wherein the molding material mounting portion has a cut-and-raised portion cut and raised from the main body portion, and presses the hole wall. It is possible to provide a molding material fixture having a feature that the hole wall of the groove hole can be pressed and held by the cut-and-raised portion, independently of the influence of the elastic contraction deformation of the main body portion that elastically contracts.

  The molding material attachment 30 of the first embodiment described with reference to FIGS. 1 to 5 is one embodiment of the above-described idea invention. However, in the molding material fixture according to the above idea invention, as in the first embodiment, the front side portion 30A which is the plate member mounting portion, the plate member locking pieces T1 and T2, and the specific locking of the regulating portion 30K. It may not be applicable to a plurality of types of plate members having different plate thicknesses resulting from the plate member locking pieces T1, T2 having a single structure. Hereinafter, the molding material attachment 300 that is applied to a plate member having a single thickness will be briefly described as a second embodiment.

  6 to 9 correspond to FIGS. 1 to 4 of the first embodiment, respectively, and the same symbols are attached to the parts having the same structural action. The metal plate member 300 ′ corresponds to the metal plate member 30 ′, and the molding material fixture 300 corresponds to the molding material fixture 30. The difference is that the front side portion 30A, which is the plate member mounting portion, the plate member locking pieces T1, T2, and the plate member locking pieces T1, T2 adjacent to the restricting portion are combined into one locking piece (cut and raised). It is configured to T12). Others are exactly the same. This locking piece T12 has the same action as the shorter locking piece T2.

  Therefore, the difference between the second embodiment and the first embodiment is that there is no locking piece corresponding to the longer locking piece T1, so that the retaining action for plate members having different thicknesses (thinner plate thickness) is eliminated. There is no (not in the state of FIG. 5), no additional force is generated to press the edge of the hole wall 10H of the plate member 10 in the state of FIG. 4, and toward the inside of the locking piece T1. The only difference is that there is no additional force for calling the molding material fixture in the insertion direction due to the bent reverse taper portion. Others are the same as those described in the first embodiment, and a description thereof will be omitted here.
