Abstract

<P>PROBLEM TO BE SOLVED: To provide a mounting structure of leg, capable of easily detaching a leg from a product in disassembling of parts for recycle. <P>SOLUTION: The structure comprises the leg 2 consisting of an elastic material, an attachment part 3a provided in a part of a product body 1, to which the leg 2 is pressed and attached, and an insert part 6 formed between the attached leg 2 and the attachment part 3a, to which a substantially bar-like drawing means 5 is inserted. The insert part 6 is provided in the attachment part 3a. Since the leg 2 can be easily removed and separated from the attachment part 3a by inserting the drawing means 5 to the insert part 6, the disassembling time can be shortened to reduce the disassembling cost, and the recycling rate can be also improved. <P>COPYRIGHT: (C)2007,JPO&INPIT

Description

  The present invention relates to a leg attachment structure that is attached to the bottom of an electric product, gas appliance, or the like.

Conventionally, as shown in FIG. 4, this type of leg mounting structure is fixed by providing a hole 102 in a back plate 101 that covers the bottom of the product body 100, press-fitting the leg 103 into the hole 102, and engaging the hole 103. (Refer to Patent Document 1, for example).
Japanese Patent Laid-Open No. 11-18937

  In recent years, aiming for a recycling society from the viewpoint of protecting the global environment, there is a need to promote recycling of household electrical appliances and other waste products.

  However, in the configuration of the conventional leg 103, the leg 103 is firmly held and fixed to the back plate 101 so that it cannot be easily removed. Therefore, when the product body 100 is disassembled for recycling or the like, the leg 103 It was difficult to remove, took time to disassemble, and had a problem that it could not be recycled because it was difficult to disassemble.

  The present invention solves the above-described conventional problems, and provides a leg attachment structure that facilitates separation of the legs from the product body, shortens the disassembly time, greatly reduces disassembly costs, and improves the recycling rate. The purpose is to provide.

  In order to solve the above-described conventional problems, the leg mounting structure of the present invention includes a leg made of an elastic material, a mounted part that is provided in a part of a product body and into which the leg is press-fitted and mounted, An insertion portion formed between a leg and the attached portion into which a substantially rod-like extraction means is inserted, wherein the insertion portion is provided in the attached portion, and the extraction means is inserted into the insertion portion. Thus, the legs can be easily detached and separated from the mounted portion, so that the decomposition time can be shortened, the decomposition cost can be reduced, and the recycling rate can be improved.

  The leg attachment structure of the present invention facilitates the separation of the leg from the mounted portion, thereby shortening the disassembly time and reducing the disassembly cost and improving the recycling rate.

  1st invention is formed between the leg which consists of elastic materials, the to-be-attached part which is provided in a part of product main body, and the said leg is press-fit, and is mounted between the said attached leg and the to-be-attached part. And an insertion part into which the rod-like extraction means is inserted, and the insertion part is provided in the attached part. By inserting the extraction means into the insertion part, the leg can be easily detached from the attachment part and separated. Therefore, the decomposition time can be shortened, the decomposition cost can be reduced, and the recycling rate can be improved.

  In the second invention, in particular, a protrusion is provided in the vicinity of the leg of the mounted portion of the first invention. By applying the pulling means to the protrusion, the lever principle can be used with a small force, The leg can be pulled out from the mounted part.

  In the third invention, in particular, a recess is provided on the end face of the convex portion of the second invention, and the leg can be reliably extracted without the extraction means being displaced by the recess.

  In the fourth invention, in particular, the convex portion of the second or third invention is provided in a substantially annular shape around the leg, and any direction can be obtained without worrying about the direction in which the work is performed when the leg is pulled out. You can also pull out the legs.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the present invention is not limited to the embodiments.

(Embodiment 1)
FIG. 1 is a partial cross-sectional view of a product main body having a leg mounting structure according to a first embodiment of the present invention, FIG. 2 is an enlarged cross-sectional view of a mounting portion for the leg, and FIG. FIG.

  In FIG. 1 to FIG. 3, reference numeral 1 denotes a product main body to which a leg 2 is attached, the bottom surface of which is closed by a back plate 3, and the leg 2 made of an elastic material such as rubber is covered at four places on the back plate 3. It is provided in each of the mounting portions 3a. The leg 2 is firmly press-fitted and fixed in the back plate hole 4 provided in the mounted portion 3a so that the leg 2 does not easily come off from the mounted portion 3a of the back plate 3 in terms of function as a product. An insertion portion 6 for inserting a predetermined rod-shaped pulling means 5 is provided in the vicinity of the leg 2 of the mounted portion 3a. Further, a convex portion 7 is disposed around the leg 2 of the mounted portion 3a in a substantially annular shape, and a recess 8 is provided at an end portion of the convex portion 7 so that the extraction means 5 is not displaced when the leg 2 is extracted. Are provided.

  With the above configuration, when the legs 2 are separated from the back plate 3 of the product body 1 for recycling, the tip of the extraction means 5 is inserted into the insertion portion 6 of the mounted portion 3a, and the convex portion provided on the mounted portion 3a. If it is rubbed against 7, the leg 2 can be easily pulled out from the back plate hole 4 of the mounted portion 3 a with a smaller force than the lever principle.

  Further, since the convex portion 7 is provided in a substantially annular shape around the leg 2 and a plurality of recesses 8 are provided on the end surface of the annular convex portion 7, the leg 2 can be securely attached without the withdrawal means 5 being displaced. The legs 2 can be pulled out, and the legs 2 can be pulled out from any direction without worrying about the working direction.

  As described above, since the leg 2 can be easily and quickly disassembled even if it is firmly fixed to the mounted portion 3a of the back plate 3, the cost for disassembly can be reduced, and the back plate 3 and the leg 2 can be reduced. It becomes possible to separate and recycle into different materials. Therefore, it is possible to promote recycling of waste products such as household electric appliances aiming at a recycling society from the viewpoint of protecting the global environment, which has been demanded in recent years.

  As described above, the leg mounting structure according to the present invention facilitates separation of the leg from the product body, shortens the disassembly time, reduces the disassembly cost, and improves the recycling rate. Not only the legs but also an elastic body, and can be widely applied to a mounting structure for various parts such as cushion rubber that is press-fitted to the product body.
