Description

  The present invention relates to a lid member that closes an opening provided in an attached member, and more particularly, to a packing structure provided between the lid member and the attached member.

  In vehicles such as small buses, a front engine system in which an engine is mounted under the floor in front of the vehicle such as around the driver's seat is often used. In such a vehicle, the height of the floor surface of the engine / transmission mounting portion (hereinafter referred to as the “storage portion”) in front of the vehicle is increased, and the height of the floor surface of the passenger interior space is set to the height of the floor surface of the storage portion. It is formed at a lower height. With such a configuration, the engine / transmission can be stored under the floor, and a sufficient indoor space can be secured.

  In front-engine vehicles, an inspection window (opening) is provided on the floor (attached member) that allows the engine / transmission to be seen from the inside of the vehicle in order to check the state of the mounted engine / transmission. It has been. The inspection hole ensures safety in the vehicle by providing a lid member as a lid member under normal conditions. Such a lid member is formed such that a gap between the floor portion and the floor surface is interposed by a packing member so that movement of foreign matter and liquid between the lid member and the floor portion can be prevented.

  An example of a conventional lid member will be described with reference to FIG. In addition, 40 shown with the dashed-two dotted line of FIG. 7 has shown the inspection window provided in the floor part of the vehicle. The lid member 50 shown in FIG. 7 has a lid body 51 formed in a rectangular plate shape capable of closing the inspection window 40, and insertion holes 52 through which fastening members are respectively inserted into the four corners of the lid body 51. Is provided. A packing member 53 is provided on the side of the lid 51.

  The packing member 53 is formed by a first packing member 54 and a second packing member 55. The packing member 53 is formed by appropriately cutting and bonding a strip-shaped (tape-shaped) packing material, which is formed of a foamable resin or the like and provided with an adhesive layer on one surface. The first packing member 54 is provided on one pair of side portions of the lid 51, is provided between the insertion holes 52, and is formed in a belt shape in which both ends are cut off at right angles to the longitudinal direction.

  The second packing member 55 is provided on the other pair of side portions, and a part of the side surface in the longitudinal direction is in contact with the end portion of the first packing member 54, and the both ends are inserted. It is formed in a band shape in which a hole portion 56 is provided at a portion where the hole 52 is located. The hole 56 of the second packing member 55 is formed by, for example, punching or the like.

  The lid member described above has the following problems. That is, when the packing member 53 is formed from a band-shaped packing material and used, it is necessary to process the hole 56 in the second packing member 55 so as not to close the insertion hole 52 of the lid 51. There is a problem that the manufacturing cost increases. Further, when the hole 56 is formed by processing, waste of packing material extracted in the shape of the hole 56 is generated.

  In order to avoid this, it is conceivable that the insertion hole 52 of the lid 51 and the packing member 53 are spaced apart by a certain distance. However, in order to separate the insertion hole 52 and the packing member 53 from each other, It is necessary to increase the size and shape. However, when the size and shape of the lid 51 are increased, the material cost required for the lid 51 increases and there is a possibility that the installation of the lid 51 may be restricted.

  Moreover, when using the packing of the substantially same shape as the flange described above, it is necessary to form it according to the shape of the lid, and there are problems such as a limitation of the packing material and an increase in manufacturing cost of the packing. When a large number of lids are produced, they can be produced in large quantities with a mold or the like according to the purpose, and can be easily manufactured. However, when the number of lids produced is small, manufacturing using a mold increases the manufacturing cost, and manufacturing is limited.

  Then, this invention aims at providing the cover member using the packing member which can be made cheap.

  In order to solve the above problems and achieve the object, the lid member of the present invention is configured as follows.

And comprising Member.

  (2) In (1), the end of the second packing member is inclined at 45 degrees with respect to the longitudinal direction, and is formed in line symmetry with respect to an intermediate position in the longitudinal direction. A lid member is provided.

  (3) In (1) or (2), the first packing member and the second packing member are formed of a band-shaped packing material in which an adhesive layer is formed on one surface, and the lid is formed by the adhesive layer. A lid member is provided that is adhered to the body.

  According to the lid member described in (1), it is possible to provide a lid member using a cheap packing member with reduced processing steps.

  According to the lid member described in (2), when the second packing member is cut from the packing material, the other of the cut portions becomes the other inclined portion as it is, so that the processing steps are reduced.

  (3) Since the packing member is adhesively fixed to the lid by the adhesive layer, the packing member is not separated from the lid at the time of inspection, and the inspection work is facilitated.

Specifically, the lid main body 135 is formed of a horizontal portion 136 and a vertical portion 137 bent from the horizontal portion 136. The lid main body 135 has an inclined stepping portion 138 formed at a part of a bent portion from the horizontal portion 136 to the vertical portion 137. The stepping portion 138 is formed by a laterally long main body 138a provided at the center and triangular side walls 138b provided on the left and right of the main body 138a.

  Further, the floor portion 130 is provided through the floor portion 130 behind the lid main body 135, and an inspection window (opening) 10 for inspecting the engine 102 and the transmission 104, and a fastening member such as a bolt on the floor portion 130. An inspection lid (lid member) 20 that is formed so as to be fixed by B and closes the inspection window 10 is provided. The inspection window 10 is formed by an opening through which the plate member 131 and the floor member 132 of the floor 130 pass.

  Further, the plate member 131 and the floor member 132 of the floor portion 130 are provided with a plurality of through holes 11 through which the fastening members B for fixing the inspection lid 20 are inserted, and the plate member 131, and the through holes 11 and the axis thereof are coaxial. A member to be fastened 12 such as a weld nut capable of fastening the fastening member B is fixed.

  The inspection lid 20 has a lid 21 that can close the inspection window 10, and a side of one main surface (opposite surface facing the floor 130) of the lid 21 corresponding to the outer periphery of the inspection window 10 in the floor 130. And a packing member 22 provided in the section. Here, the inspection lid 20 has a packing member 22 on the side facing the floor 130 of the lid 21. The inspection lid 20 has a gap between the lid 21 and the floor surface of the floor portion 130 when the lid body 21 is fixed to the floor portion 130 with the fastening member B in order to close the inspection window 10 by the packing member 22. Thus, foreign substances, liquids, and the like are formed in a configuration that can prevent the inspection window 10 from entering the vehicle interior.

  As shown in FIGS. 3 to 5, the lid body 21 is formed in a rectangular plate shape, and has a recess 23 that is recessed from the side of the lid body 21 by a predetermined distance from the inside. The lid body 21 has an outer dimension equal to or greater than the sum of the outer dimension of the inspection window 10 and the width of the packing member 22. In the lid body 21, insertion holes 25 through which the fastening members B are inserted are formed at the four corners of the lid body 21.

  As shown in FIG. 4, the lid 21 is exposed to the outside because the other main surface provided with the recess 23 is located on the side opposite to the floor 130. For this reason, the upper cover 24 having the same appearance as that of the floor material 132 is attached to the recess 23 so that the appearance of the lid 21 can be improved.

  Further, when one main surface protrudes from the concave portion 23, the lid body 21 protrudes from one portion of the main surface (of the concave portion 23) when fixed to the floor portion 130 as shown in FIG. The back side) is located on the inspection window 10.

  The packing member 22 includes a pair of first packing members 26 and a pair of second packing members 27. The packing member 22 is formed of a foamable resin material or the like. The packing member 22 cuts a long strip-shaped (tape-shaped) packing material provided with an adhesive layer having adhesive properties such as a double-sided tape on one surface, whereby the first packing member 26 and the second packing member 27 are cut. Is formed. The width of the packing member 22 can be set as appropriate according to the size and shape of the lid 21, the material of the packing member 22, the usage status of the vehicle 100, and the like.

  The first packing member 26 is provided between the insertion holes 25 of one pair of side portions (opposite side portions) of the lid body 21 so as to be separated from the insertion holes 25, and both ends thereof are perpendicular to the longitudinal direction. It is formed in a band shape. That is, the first packing member 26 is formed in a rectangular shape by cutting the packing material at a shorter length than between the insertion holes 25 and at a right angle to the longitudinal direction of the packing material.

  The second packing member 27 is provided on the other pair of side portions (opposite side portions), and a part of the side surface abuts on the side portion (side surface) cut at a right angle of the first packing member 26 and both ends thereof. Are trapezoidal and slanted with respect to the longitudinal direction. The inclination of the end of the second packing member 27 does not contact the insertion hole 25, that is, the insertion hole 25 and the inclination of the second packing member 27 are opposed to each other in the radial direction of the insertion hole 25. The second packing member 27 is formed at an inclination angle that is separated in the radial direction. The inclination angle is, for example, 45 ° with respect to the longitudinal direction of the second packing member 27.

  More specifically, as shown in FIG. 6, the second packing member 27 is made of a long strip-shaped (tape-shaped) packing material 22A, and the length between the end portions is substantially the same as the side portion (a pair of first pieces It is formed by cutting with a cutting tool D in which the cutting direction is inclined by 45 ° with respect to the longitudinal direction of the packing material 22A every interval of the packing member 26). In this way, by cutting the packing material 22A at 45 °, the second packing member 27 is formed in a trapezoidal shape symmetrical with respect to the center line C in the thickness direction located at the center in the longitudinal direction. In addition, the edge part of adjacent packing raw material 22A also has the same inclination by one cutting | disconnection. That is, the inclined portion of the adjacent second packing material 27 is formed at one time.

  The pair of the first packing member 26 and the second packing member 27 are adhered and fixed to the side portion of the lid body 21 by an adhesive layer provided on one surface, so that the inspection lid 20 and the inspection window 10 are fixed. A packing member 22 that can pack (seal) the surrounding floor portion 130 is formed. The packing of the packing member 22 is not particularly required to be sealed as long as it can prevent the movement of liquid or foreign matter.

  Note that the pair of side portions (opposite side portions) of the lid body 21 is a pair of side portions opposed to each other. For this reason, the rectangular lid 21 has two pairs of side portions (one and the other), but the first packing member 26 and the second packing member 27 may be provided on either side.

  According to the vehicle 100 using the inspection lid 20 configured as described above, the inspection lid 20 provided on the floor portion 130 is used to close the inspection window 10 during normal use such as during operation of the vehicle 100. It is possible to prevent foreign matters, liquids, and the like from entering the vehicle interior from the inspection window 10 through the gap between 20 (the lid body 21) and the floor surface of the floor portion 130 (the surface of the floor material 132).

  At the time of maintenance and inspection of the engine 102 and the transmission 104 provided in the vehicle 100, the inspection window 10 is exposed by unscrewing the fastening member B of the inspection lid 20 and removing the inspection lid 20. For this reason, the engine 102 and the transmission 104 can be visually recognized from the inspection window 10.

  In addition, the packing member 22 used for the inspection lid 20 has the first packing member 26 formed in a rectangular shape and the second packing member 27 formed in a symmetrical trapezoidal shape having an inclination of 45 °. They are separated without interfering with the insertion hole 25. For this reason, the packing member 22 can be bonded and fixed to the lid body 21 with the adhesive layer without closing the insertion hole 25.

  For this reason, the processing part (for example, the hole part 56 of FIG. 7) for preventing interference with the insertion hole 25 is not required, that is, it is only necessary to cut the packing material 22A at 45 °. For this reason, it also reduces the processing steps. Further, the cutting may be performed only by cutting the packing material 22A by providing an angle in the longitudinal direction, and does not require a special tool or the like for drilling.

  Further, it is possible to prevent the generation of dust during drilling of the hole portion 56 and the like in FIG. Further, by setting the inclination of the second packing member 27 to 45 °, it is only necessary to alternately cut the inclination, and the second packing member 27 having the same shape can be produced, so that productivity is good.

  Moreover, the 2nd packing member 27 can be used for either of a pair of side part only by one type by making it into a line symmetrical trapezoid shape. Further, when the second packing member 27 is cut from the packing material, the other of the cut portions becomes the other inclined portion as it is, that is, the end shape of the adjacent second packing member 27 is formed by one cutting. Therefore, the machining process is reduced.

  Since two second packings having the same shape may be used, the number of parts required for the inspection lid 20 can be reduced. That is, production management becomes easy, and versatility and productivity can be improved. As a result, the manufacturing cost is reduced.

  Furthermore, by using foaming resin for the packing member 22, when the inspection lid 20 is fixed to the floor portion 130, the packing member 22 is crushed so that the level difference between the floor surface of the floor portion 130 and the inspection lid 20 is minimized. Therefore, the floor 130 of the vehicle 100 can be made as flat as possible.

  Further, since the packing member 22 is adhesively fixed to the lid body 21 by the adhesive layer, the packing member 22 is not separated from the lid body 21 even when the inspection lid 20 is separated from the floor portion 130 at the time of inspection. For this reason, it is not necessary to attach the packing member 22 to the lid 21 at the time of inspection, and the inspection work is facilitated.

  As described above, according to the vehicle 100 using the inspection lid 20 having the packing member 22, the packing member 22 includes the first packing member 26 having a band shape and a rectangular shape, and a trapezoidal shape having a 45 ° inclination. By using the two packing members 27, the processing steps of the packing member 22 can be reduced. Further, the manufacturing cost of the packing member 22 can be reduced and the productivity can be improved.

  Note that the present invention is not limited to the above-described embodiment as it is, and can be embodied by modifying the constituent elements without departing from the scope of the invention in the implementation stage. For example, in the above example, the vehicle 100 is a small bus, but the floor heat insulating structure of the present invention is not limited to a small bus. In the above-described example, the packing member 22 is formed by cutting a band-shaped packing material formed of a foamable resin. However, the packing member 22 may not be a foamable resin, and may cut a rectangular flat plate-shaped packing material. May be formed.

  In addition, various inventions can be formed by appropriately combining a plurality of components disclosed in the embodiment. For example, some components may be deleted from all the components shown in the embodiment. Furthermore, constituent elements over different embodiments may be appropriately combined. In addition, various modifications can be made without departing from the scope of the present invention.
