Description

 The present invention relates to a frame member for mounting a door, and more particularly, to a technique for providing a light door frame material.

  Conventionally, four sets of door frame members for attaching doors are arranged on the left, right, and top, and the doors can be stopped at predetermined positions by door stops provided inside the door frame members.

  As the door frame material, a door frame material having a width adapted to the wall thickness of the door wall opening is used.

  As a prior art of such a door frame material, a structure of a door frame material described in Patent Document 1 is known. As shown in FIG. 6, the door frame material 1 for attaching the door 12 includes a frame member main body 2 composed of two sets of vertical members 3 and 4 and a door stop 9 attached to the surface of the frame member main body 2. Is done.

  The frame member body 2 is made of a laminated material formed by laminating and bonding a single plate made of natural wood having a thickness of about 0.5 mm, and two sets of vertical members 3 and 4 made of the laminated material are used. It connects by making the recessed part 5 and the convex part 6 which were each formed along the length direction fit. On the surface of the door frame member 1, a recess 8 for the door stop 9 is formed so as to straddle the fitting portions 7 of the two sets of vertical members 3 and 4.

  The door stop 9 is formed of a laminated material obtained by laminating and bonding single plates made of natural wood in the same manner as the frame member body 2, and is processed with a thickness of about 10 mm, a width of about 40 mm, and a length of about 1820 mm. A convex portion 10 is formed integrally with the concave portion 8 formed in the connecting portion of the frame member body 2 on the rear surface while being chamfered.

And the door frame material 1 is formed by making the convex part 10 formed in the back surface of the door stop 9 fit and adhere to the recessed part 8 for the door stop 9. As shown in FIG.
Japanese Utility Model Publication No. 7-32173

  However, since the door frame material (including the door stop) is made of a laminated material having a predetermined thickness formed by adhering a single plate of natural material, the door frame material becomes heavy and is difficult to process and install. There was a problem.

  Therefore, the present invention has been made in view of the problems of the related art, and an object thereof is to provide a light door frame material.

  According to the first aspect of the present invention, there is provided a core material in which at least three sets of wooden solid members having a flat rectangular parallelepiped shape are arranged in the longitudinal direction and a spacer is sandwiched between the respective wooden strength members. The periphery of the core material is covered with a surface material except for a continuous portion, and a door stop is inserted into a concave groove formed by both ends of the surface material and a part of the core material, and the door contact Is characterized by being fixed to the wood strength member.

  In the case of this door frame material, a wood strength member is disposed in the longitudinal direction, and a spacer is provided between each of the wood strength members, and a material that does not particularly require strength can be used for the spacer.

  By covering the periphery of the core material with a surface material, a concave groove for door contact is naturally formed between both ends of the surface material and a part of the core material.

  Invention of Claim 2 is the door frame material of Claim 1, Comprising: The easy bending part by which the cross section of the said surface material was rolled at right angle in the area | region where the said surface material is bent along the said core material Is formed.

  In the case of this door frame material, since the surface material is bent along the core material, an easy-bending portion in which the cross-section of the surface material is bent at a right angle is formed. It can be bent along the bent portion.

  According to the first aspect of the present invention, the core material in which the wood strength member is disposed in the longitudinal direction and the spacer is sandwiched between the wood strength members may be a material that does not require strength. Various inexpensive materials can be selected.

  For this reason, the door frame material can be manufactured at a low cost by using a naturally-friendly material. Moreover, the weight of the door frame material is reduced.

  By covering the periphery of the core material with a surface material, a concave groove for door contact is naturally formed between both ends of the surface material and a part of the core material. For this reason, since the process of the ditch | groove for door stop is unnecessary, a door frame material can be manufactured at low cost.

  And since the said door stop is fixed to the said wooden strength member, intensity | strength can be hold | maintained.

  According to the second aspect of the present invention, since the surface material is bent along the core material, an easily bendable portion in which a cross section of the surface material is bent at a right angle is formed. Can be easily bent.

  For this reason, since it is excellent in moldability and looks good, the commercial value is improved.

<First Embodiment of the Present Invention>
Embodiments of the present invention will be described below with reference to FIGS.

<Composition of door frame material>
As shown in FIGS. 1, 2, 3, and 4, the door frame member 21 for mounting the door of the present invention has four sets of wooden solid members 22 in the shape of flat rectangular parallelepiped in the longitudinal direction, A long core member 24 having a structure in which three sets of spacers 23 are sandwiched between the wood strength members 22 is formed.

  Further, the periphery of the core material 24 in the longitudinal direction is covered with the surface material 25, but the surface material 25 is not covered with a portion 22 a continuous in the longitudinal direction of the core material 24.

  A door stop 28 for stopping the door at a predetermined position is inserted into a concave groove 27 formed by both end portions 26 of the surface material 25 and a part 22a of the core member 24, and the door stop 28 is It is fixed to the woody strength member 22.

  The door frame member 21 has a width M and a height N (the height N1 of the surface material 25 and the protruding height N2 of the door stop 28) corresponding to the wall thickness of the wall opening to be attached. The door frame member 21 has a height N1 = 24 mm, a width M = 110 mm, and a length L = 2047 mm.

  The concave groove 27 of the door stop 28 is not necessarily formed at the center of the door frame member 21 in the width M direction, and the position thereof is appropriately determined from the relationship with the door.

  The flat rectangular parallelepiped wooden strength member 22 has a length S = 70 mm, a width T = 104 mm, and a height D = 18 mm, and is arranged in a straight line with a pitch P.

  The spacer 23 has the same height D and width T as the wood strength member 22 and a length P1.

  Here, since the pitch P of the wooden strength member 22 and the length P1 of the spacer 23 are the same length, the total length L of the core member 24 is 4 × S + 3 × P.

  Four easy-bending portions 30 are continuously formed in the longitudinal direction on the surface material 25 so as to be easily bent when the core material 24 is surrounded. The easy-bending portion 30 has a V shape in which the cross-section of the surface material 25 is bent at a right angle of 90 degrees, leaving a surface thin plate portion 25 a as the outermost surface layer of the surface material 25 in the cross-section of the surface material 25. Are formed symmetrically.

 Now, assuming that the development width G and length L of the surface material 25 are not covered, a portion 22a (referred to as width Q) of the core material 24 is not covered. Therefore, if the thickness K of the surface material 25 is ignored, G = (M + 2 × N1 + M1 + M2). ), M = M1 + M2 + Q.

  Here, as described above, since the concave groove 27 of the door stop 28 is not necessarily formed at the center in the width M direction of the door frame member 21, the length of the concave groove 27 from the end portion 25b of the surface material 25 is long. The lengths M1 and M2 are not necessarily the same length.

 Since the wooden strength member 22 is required to have a strength that can securely hold the fixing member when the door frame member is assembled to the wall of the building with a fixing member such as a screw, a plywood or a particle material is used, for example.

  The spacer 23 is made of, for example, a core material obtained by continuously forming a semi-core paper or non-combustible paper (such as aluminum hydroxide paper) into a honeycomb shape or a corrugated shape, a material called a corrugated cardboard, and the like. Since it is large, it can be reduced in weight, and it can be easily processed with excellent stretchability and cushioning properties.

 The surface material 25 is formed, for example, by sticking a surface thin plate portion 25a of a wood-tone resin sheet decorative material to a medium density wood fiber board (MDF) formed of wood powder and resin.

  As shown in FIG. 5, the cross-sectional shape of the door stop 28 is a convex shape, and the size of the convex portion 28a is, for example, a width Q = 17 mm and a height K = 3 mm. On the other hand, the shape of the concave groove 27 formed by covering the periphery of the core material 24 with the surface material 25 also has the same width Q and depth K (same as the thickness K of the surface material 25). For this reason, the convex portion 28 a of the door stop 28 is inserted into the concave groove 27 without a gap and is fixed to the wood strength member 22.

  For this reason, since the impact force from the door is transmitted from the door stop 28 to the wood strength member 22, the force can be distributed over the entire door frame member 21 to withstand the impact.

 The door stop 28 is made of medium density wood fiber board (MDF) or the like.

  The members are fixed to each other with an adhesive or the like as necessary.

<Operation of door frame material 21>
Thus, since the door frame material 21 is constituted by the so-called flash structure as described above, natural materials are not used frequently, so that natural destruction is reduced as much as possible, and it is gentle to nature and lowers the cost. it can.

  Since the easy bending part 30 is provided in the surface material 25, the core material 24 can be covered easily. Since the spacer 23 can be easily processed and can be inserted into the space surrounded by the wooden strength member 22 and the surface material 25, the door frame material 21 becomes lighter and can be easily processed and installed.

  When the door frame member 21 is attached to the building, the door frame member 21 is composed of the left and right and upper three sets, and the lower portion is not used to eliminate the step on the floor, and is used in a so-called barrier-free configuration. Is done.

  The door frame member 21 is attached to the wall of the building by first attaching the door frame member 21 with the fixing member such as a screw through the wooden strength member 22 in a state where the door stop 28 is not fixed. The door stop 28 is fixed to the recess 27 with a screw or an adhesive.

 Moreover, when fixing the hinge for doors to the said door frame material 21 of either right and left, it can adhere using the said wood strength member 22. FIG. In this case, the number of the wood strength members 22 may be arranged in the region according to the required number of hinges.

 Thus, since the door frame material 21 is constituted by the so-called flash structure as described above, since natural materials are not used frequently, it leads to a reduction in natural destruction as much as possible. Can do.

  Moreover, since the door frame material 21 becomes light, processing and installation can be facilitated.

  As mentioned above, although embodiment of this invention was described based on drawing, all said Example showed an example of this invention, and it cannot be overemphasized that this invention should not be limited to these. Absent.

  For example, the convex portion 28a of the door stop 28 can be inserted and fixed in a groove deeper than the groove 27 formed by molding the wood strength member 22 and covered with the surface material 25. As a result, the door contact 28 is firmly fixed to the door frame member 21, so that the impact force received when the door is closed can be received more firmly and stably.

  In this case, the portion of the spacer 23 is formed lower by the height K of the convex portion 28a.

  The cross-sectional shape of the door stop 28 may be a rectangular shape without the convex portion 28a.

It is a perspective view which shows the door frame material in embodiment of this invention. It is an expansion | deployment perspective view which shows arrangement | positioning of the core material 24 which consists of the wooden strength member 22 and the spacer 23 in embodiment of this invention. It is a development perspective view of surface material 25 in an embodiment of the present invention. FIG. 4 is a detailed view of “A” in FIG. 3 in the embodiment of the present invention. It is a perspective view which shows the core material 24 covered with the door stop 28 and the surface material 25 in embodiment of this invention. It is sectional drawing which shows the door frame material in a prior art example.
