Abstract

<P>PROBLEM TO BE SOLVED: To provide an adjustable frame member manufactured in a smaller number of steps with a simplified work in each step, and equipped with a cushioning member that is resistant to slipout and does not generate waste material. <P>SOLUTION: The adjustable frame member is formed of frame members 10 assembled in an opening R formed in a skeleton B of a building, and adjustors 20 which are each extensively/contractibly embedded in an outer peripheral surface of the frame member 10 such that its tip protrudes from the frame member 10, and function to adjust a gap G between the frame member 10 and the skeleton B by extending/contracting its front surface to abut on the skeleton B. Herein a hot melt 30 in a molten state is fed to the tip of the adjustor 20 and then hardened to cover the tip, and therefore the hot melt serves as a cushioning material. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

  The present invention uses an adjustment tool that adjusts the distance from the housing when the frame material is assembled in the opening formed in the housing of the building, and a hot melt having a buffer function is provided at the tip of the adjustment tool. This relates to the adjustment frame material.

  Conventionally, for example, when assembling a frame material in an opening formed in a housing of a building such as a house, a large number of thin plate materials are prepared, and after the frame material is assembled, the housing and the frame material The gap between the two was adjusted by filling the gap between the two.

  However, this method has a problem that the opening part is deformed due to a change in shape due to the hanging of the door or a change in the size of the frame material over time, and the opening and closing of the door is likely to cause problems. Needed work by a worker.

  In view of these points, in recent years, instead of using a thin plate material, means for embedding a telescopic adjustment tool in the frame material has been considered. This adjuster can be carried into the construction site in a state separated from the frame material, but if you embed the adjuster in the frame material and ship it at the factory, you can save time at the construction site. That's how it goes.

This adjustment tool is preferably shipped from the factory without protruding from the frame material. If it protrudes, it may collide with other building materials during transportation or construction and damage it.
However, in practice, there is a frame material that does not have a thickness sufficient to completely embed the adjuster, and in this case, the tip of the adjuster protrudes.

  For this reason, a method of packing the entire frame material with a sheet of polyethylene foam has been performed, but many polyethylene foam sheets are necessary and wasteful.

Recently, as shown in FIGS. 7 and 8, a small polyethylene foam cushioning sheet material 40 is prepared so as to cover only the protruding portion of the adjusting tool, and this is protruded from the adjusting tool 20 at the time of factory shipment. The method of sticking to the front end surface is adopted.
Although this method can greatly reduce the amount of polyethylene foam used and reduce the packaging cost, it has the following problems.

(1) The number of manufacturing processes and in-process operations are complicated and cost increases.
First, a sheet of polyethylene foam having a predetermined thickness is manufactured at a buffer material manufacturing factory, and an adhesive material is applied to the back surface. Next, a release paper is attached to the adhesive material application surface, and cut into a predetermined size to obtain a small and square buffer sheet material 40.
The buffer sheet material 40 is transported to the frame material manufacturing factory, and the release paper 41 is peeled off one by one, and the troublesome work of pasting on the front end surface of the adjustment tool 20 is required (see FIG. 7).
(2) Easy to drop off during transportation and handling.
The buffer sheet material 40 is affixed to the front end surface of the adjustment tool 20, but since there are usually a plurality of assembly protrusions 20a on this front end surface, it cannot be affixed in a close contact state, and peels off and falls off. Easy (see FIG. 8).
(3) Waste is generated in the buffer sheet material.
Since the buffer sheet material 40 has a quadrangular shape and the adjuster 20 is generally circular, even if the buffer sheet material 40 is formed small, its periphery protrudes from the outer periphery of the tip of the adjuster 20 and waste occurs.

(4) When the frame material is assembled without removing the cushioning material, a problem occurs.
If the buffer sheet material 40 is forgotten to be removed from the front end surface of the adjustment tool 20, the plurality of assembly protrusions 20a provided on the front end surface of the adjustment tool will not bite into the housing, so the frame material can be held with only a few screws. It becomes a situation to cause a failure due to insufficient strength.

  Accordingly, an object of the present invention is to provide an adjustment frame member provided with a buffer member that can simplify the number of manufacturing steps and in-process operations, is difficult to drop off, and does not waste material.

  In order to achieve the above object, an adjustment frame material (1) with hot melt according to claim 1 of the present invention is a frame material to be assembled to an opening (R) formed in a housing (B) of a building. (10) and an outer peripheral surface portion of the frame member (10), the front end portion of the frame member (10) protrudes from the frame member (10) so as to be extendable and contractable, and expands and contracts to bring the front end surface into contact with the housing (B). An adjustment tool (20) that adjusts the gap (G) between the frame material (10) and the housing (B), whereby the tip of the adjustment tool (20) is hot-melted ( 30) was supplied in a molten state and cured to be coated and functioned as a buffer material. The coated hot melt (30) is solidified by natural cooling or forced cooling.

  The invention according to claim 2 is a substantially nut-like fixing member (the fixing member (20) is embedded and fixed in the outer peripheral surface portion of the frame member (10), and has a thread on the inner peripheral surface ( 21) and an insertion hole through which a screw (S) for fixing the frame member (10) to the housing (B) is inserted along the axial direction in a substantially bolt shape screwed to the fixing member (21). And a telescopic member (22) having a distal end portion protruding from the outer peripheral surface of the frame member (10) and including the distal end portion of the insertion hole (23). It is characterized by being coated with the hot melt (30).

  Furthermore, in the invention described in claim 3, a portion from the tip of the insertion hole (23) to a substantially intermediate portion is a hole larger than the diameter of the screw (S), and is inserted through the outer peripheral surface of the screw (S). A gap is formed between the hole (23) and the hole (23).

  Furthermore, the invention according to claim 4 has a low melting point that softens the hot melt (30) by heat generated when the screw (S) is screwed into the housing (B) from the insertion hole (23). It is characterized by becoming.

  Symbols in parentheses indicate corresponding elements or corresponding matters described in the drawings and the best mode for carrying out the invention described later.

  According to the adjustment frame material with hot melt according to claim 1 of the present invention, the frame member assembled in the opening formed in the housing of the building, the outer peripheral surface portion of the frame member, the tip portion from the frame material In an adjustment frame member comprising an adjustment tool that is embedded in a projecting state so as to be stretchable and expands and contracts to adjust the distance between the frame member and the frame member by abutting the distal end surface against the frame member, Since the hot melt was supplied in a molten state and cured to coat and function as a buffer material, the following effects were exhibited.

(1) The number of manufacturing steps and in-process operations can be simplified and costs can be reduced.
Conventionally, all the processes and operations provided in the buffer material manufacturing factory are unnecessary.
Also, in the frame material manufacturing factory, automation is easy and manual work is not required. It suffices to provide only the step of supplying the hot melt in the molten state to the tip of the adjuster embedded in the frame material and covering the tip.
(2) It does not fall off during transportation or handling and has an excellent buffering effect.
Since the hot melt is supplied in a molten state and solidifies, it adheres firmly to the tip of the adjuster. At this time, even if there are a plurality of assembly protrusions on the front end surface of the adjustment tool, they flow into and adhere to the intermediate portions (see FIG. 6). Therefore, even if it comes into contact with other frame materials or the like, it does not fall off and has an excellent buffering effect.
(3) There is no waste in the material.
Since this hot melt is supplied in a molten state to the tip of the adjustment tool, only an amount corresponding to the area of the tip can be used. Therefore, there is no waste in hot melt.

(4) Even if the frame material is assembled without removing the hot melt, it is difficult to cause problems.
Even if you forget to remove the hot melt from the tip of the adjuster, the hot melt is soft after curing, so the multiple assembly protrusions provided on the tip of the adjuster are relatively easy to bite into the housing. Because it is difficult to slide against the housing, it is difficult to cause problems.

  Moreover, according to the adjustment frame material with a hot melt of Claim 2, in addition to the effect of the invention of Claim 1, the adjustment tool is embedded and fixed in the outer peripheral surface portion of the frame material, and the inner periphery A substantially nut-shaped fixing member having a thread on the surface, and a substantially bolt shape screwed to the fixing member, and has an insertion hole through which a screw for fixing the frame member to the housing is inserted along the axial direction. In addition, since the tip end portion of the expansion / contraction member including the tip end portion of the insertion hole is covered with the hot melt, the tip portion protrudes from the outer peripheral surface of the frame member. It can prevent more reliably.

  That is, since the melted hot melt also penetrates into the distal end portion of the insertion hole and solidifies, it is firmly assembled by the stretchable member, and thus is difficult to fall off.

  Furthermore, according to the adjustment frame material with hot melt described in claim 3, in addition to the operational effects of the inventions described in claims 1 and 2, the portion from the tip of the insertion hole to the substantially intermediate portion is formed on the screw. Since the hole is larger than the diameter, and a gap is formed between the outer peripheral surface of the screw (the highest part of the thread) and the insertion hole (inner wall), when the screw is inserted into the insertion hole and screwed into the housing, Even when the frame material is assembled without removing the material, or when the hot melt covering the tip of the elastic member is removed, but the hot melt filled in the tip of the insertion hole remains, Of the hot melt filled in the tip portion of the insertion hole, unnecessary one can be discharged from a gap formed between the outer peripheral surface of the screw and the insertion hole.

By the way, if this gap is not formed, the hot melt filled in the insertion hole is likely to move between the elastic member and the housing, and there is a possibility that construction failure may occur. By forming the gap, it is possible to prevent the occurrence of construction defects.
In addition, specifications such as hot melt, the material of the adjustment tool, the dimensions of the insertion hole, etc., so that the hot melt filled in the distal end portion of the insertion hole remains even after the hot melt covering the distal end portion of the elastic member is removed. If is selected, it can be imparted with the intention of preventing the screw inserted through the insertion hole from loosening. In this adjustment frame material, a screw is inserted into the housing through the insertion hole of the expansion / contraction member, but after screwing, the hot melt filled in the tip of the insertion hole is interposed between the outer peripheral surface of the screw and the insertion hole. It becomes a tightly packed state and prevents the screws from loosening.

  Furthermore, according to the adjustment frame described in claim 4, in addition to the effects of the invention described in claims 1 to 3, the hot melt is caused by heat generated when the screw is screwed into the housing from the insertion hole. Since it has a low melting point that softens, the screw inserted through the insertion hole is sufficiently melted when screwed into the housing, and unnecessary parts are easily discharged from the large diameter part. Adhere in close contact with the insertion hole. Thereby, generation | occurrence | production of a construction defect can be prevented in advance and the loosening of the screw can be further effectively prevented.

With reference to FIG. 1 thru | or FIG. 4, the adjustment frame material 1 with a hot melt which concerns on embodiment of this invention is demonstrated.
FIG. 1 is a front view showing a state in which the adjustment frame according to the present embodiment is assembled to the housing B. FIG. 2 to 4 are partial cross-sectional views showing the adjustment frame according to the present embodiment, in which FIG. 2 shows a state in which the screw S has started to be inserted into the insertion hole 23, and FIG. 3 shows that the screw S is screwed into the housing B FIG. 4 shows a state where the screw S is screwed into the housing B. The same parts as those shown in the conventional example are denoted by the same reference numerals.

The adjustment frame material 1 with hot melt is mainly composed of a frame material 10, an adjustment tool 20, and a hot melt 30. In this embodiment, the three adjustment frame members 1 are assembled to the left and right ends and the upper end of a rough opening R formed in the housing B (an opening set slightly larger than the opening formed by the frame member 10). Thus, an opening frame is formed. The adjustment frame material 1 can be transported to the construction site as a single unit, or can be transported to the construction site after being assembled into an opening frame at the factory.
The frame material 10 constitutes a main body portion of the adjustment frame material 1 and forms an opening of a building.

The adjusting tool 20 includes a resin fixing member 21 and a metal elastic member 22.
Among them, the fixing member 21 is embedded in and fixed to the outer peripheral surface portion (side surface portion or upper surface portion) of the frame member 10 and has a substantially nut shape having a thread on the inner peripheral surface. A plurality of engaging ridges 21a are provided on the outer peripheral surface of the fixing member 21 to prevent the fixing member 21 from coming off from the frame member 10, and a flange for determining the assembly position with the frame member 10 is provided at the tip. A piece 21b is provided around.

  The elastic member 22 has a substantially bolt shape that is screwed to the fixing member 21, and has an insertion hole 23 along the axial direction of the central portion. A screw (wood screw) S for fixing the frame member 10 to the housing B is inserted into the insertion hole 23. The insertion hole 23 has a portion (small diameter portion) larger than the diameter of the screw S in a portion extending from the tip to a substantially intermediate portion, and a gap is formed between the outer peripheral surface of the screw S and the insertion hole 23. Become. A portion from the substantially middle portion to the rear end is a large diameter portion 23a having a diameter larger than that of the small diameter portion. Further, a plurality of assembly protrusions 20a are provided on the distal end surface of the elastic member 22 so as to be firmly assembled without sliding on the housing B.

  A hexagonal hole 23b is formed at the rear end of the large diameter portion 23a. By inserting a hexagon wrench into the hexagonal hole 23b and rotating clockwise, the elastic member 22 is extended so that the end surface thereof is brought into contact with the casing B, and the gap G between the casing B and the frame member 10 is adjusted.

  As shown in FIG. 5, the hot melt 30 is supplied from the applicator A to the distal end portion of the elastic member 22 in a molten state. As a result, as shown in FIG. The outer peripheral surface is covered and enters the tip of the insertion hole 23. The hot melt 30 is made of a resin having a low melting point that is softened by heat generated when the screw S is screwed into the housing B from the insertion hole 23 (melting point is about 65 to 70 ° C.) and is soft.

In the adjustment frame according to the present embodiment having the above-described configuration, the hot melt 30 can be provided at the distal end portion of the elastic member 22 in the frame material manufacturing factory.
The hot melt 30 is basically removed from the front end surface of the adjusting tool 20 at the construction site. Even if the hot melt 30 is forgotten to be removed, the hot melt 30 is soft after curing, so it is provided on the front end surface of the adjusting tool 20. The plurality of assembly protrusions 20a that are formed are relatively easy to bite into the housing B, and have a viscosity and are difficult to slide with respect to the housing B.

  Further, since the hot melt 30 is supplied in a molten state to the distal end portion of the expansion / contraction member 22 and is then solidified and firmly adhered, it does not fall off even if it comes into contact with another frame member 10 or the like. A plurality of assembly protrusions 20a are provided on the distal end surface of the elastic member 22, but the hot melt 30 in a molten state adheres closely to the distal end surface in close contact with the assembly protrusion 20a. This is because the hot melt 30 is also filled in the insertion hole 23 of the elastic member 22 and can be strongly assembled to the elastic member 22.

In addition, since the hot melt 30 is supplied in a molten state to the tip of the adjuster 20, only the amount corresponding to the area of the tip can be used, and the hot melt 30 is not wasted.
Further, since the hot melt 30 is in a state of being tightly filled between the outer peripheral surface of the screw S and the insertion hole 23, loosening of the screw S is prevented.
Furthermore, since a hole portion (small diameter portion) larger than the diameter of the screw S is formed in the insertion hole 23, when the screw S is screwed into the housing B, an extra hot melt 30 is introduced from the gap between the hole portion and the screw S. Is discharged (see FIG. 3), and it is possible to prevent the occurrence of poor construction.
