 In FIG. 1, a furniture cradle (hereinafter simply referred to as a furniture cradle) according to the present embodiment, which is separable from materials, is generally indicated by reference numeral 10. As described above, sound and vibration between the furniture and the floor surface are attached to and fixed to the leg end of the furniture (not shown) and contact with the floor surface when the furniture is used. It is designed to be used to prevent vibrations and soundproofing, and to prevent damage to the floor where the furniture is installed. It has a fixing bracket element 12 made of a nail element or a bolt element for mounting and fixing to the head. The fixing bracket element 12 includes an engagement shaft portion 12a that is driven or screwed into a leg end of the furniture or the like, and a head portion 12b provided at a terminal portion of the engagement shaft portion 12a. , You may use commercially available iron-based metal material bolt screw and nail material, etc., select and use thick nails and bolt screws of appropriate diameter and length in advance, or bolt-shaped members designed and set in advance, It may be composed of a nail member. In any case, the nail or bolt element 12 is formed of a metal-based material because it requires strength.

The fixing bracket element 12 is held and supported by a receiving seat 14 through its head 12b. The receiving seat 14 is formed by a lower receiving seat portion 16 and an upper receiving seat portion 20, and is shown in FIG. Has a receiving hole 40 (see FIG. 2), which will be described later, formed in a recessed shape in the lower receiving portion 16 that is not displayed, and the head 12b of the fixing bracket element 12 is received in the receiving hole 40. . The lower seat portion 16 is preferably formed as a molded part of a synthetic resin material material suitable for furniture use, such as tetrapolyethylene, polyethylene, polyamide, polypropylene, etc., as well-known resin materials, and at the bottom as required. A felt plate-like member is obtained in advance from the same resin material as that of the main body portion 16a, and a felt seat surface 16b formed from the same member in a required shape and size is integrally formed by a material resin by an insert mold, and an installation surface such as a floor surface Provide a contact surface to.
Further, the upper seat portion 20 is formed so as to clamp and fix the fixing metal element 12 in cooperation with the lower seat portion 16 and to have a contact surface on the leg end of furniture on the upper surface. The fixing bracket element 12 has a through-hole through which the engagement shaft portion 12a passes, and is engaged with and coupled to the lower seat portion 16 by a coupling means described later. Formed to hold element 12.

  The upper seat portion 20 of the seat 14 may be formed of an appropriate synthetic resin material in the same manner as the lower seat portion 16, or it is rich in molding processability such as an aluminum material and has appropriate flexibility. You may form with a metal material.

Also, in FIG. 1, an adapter 18 is shown in the upper part of the fixing metal element 12, and the adapter 18 is formed as a hollow annular part with a central portion penetrating the fixing portion 12. A single material having a jaw portion through which the engaging shaft portion 12a of the element 12 passes and which engages with the head portion 12b to fix and hold the fixing bracket element 12 to the lower receiving portion 16 of the receiving seat 14 The adapter 18 is a component that can be omitted when the fixing bracket element 12 is a relatively large-diameter bolt or nail element. Therefore, in the embodiment shown in FIG. 3 to be described later, the adapter 18 is omitted, and the furniture cradle 10 according to the embodiment having a configuration in which the adapter is fixed and held by the jaw portion of the upper seat portion is shown. It was.
The above-described adapter 18 may be a resin material, or may be formed at a low cost as one mass-produceable part by an appropriate processing method such as molding, extruding, and shaving using a metal material such as aluminum, copper, or iron. .

  As described above, the furniture cradle 10 according to the present invention is formed with a plurality of (three to four) component elements as the main elements as described above, but these multiple component elements 12, 14 (16 + 20) , 18 are formed as separate parts, and are formed of the same or different materials.

  Here, referring to FIG. 2, by assembling the fixing bracket element 12, the lower receiving portion 16, the receiving portion 14 including the upper receiving portion 20, the adapter 18 and the like, which are formed as separate parts, furniture items are assembled. A state in which the cradle 10 is formed is shown. That is, the fixing bracket element 12 has its engagement shaft portion 12a upright, and is seated in the recess-shaped receiving hole 40 of the lower seat portion 16 by the head portion 12b. The jaw portion 18a of the adapter 18 is pressed downward to be held in the receiving hole 40 immovably. In this case, the adapter 18 also functions to reinforce the mechanical strength when the engagement shaft portion 12 of the fixing metal element 12 has a relatively small diameter. After the adapter 18 is mounted, the upper seat portion 20 is attached from above, and the fixing bracket element 12 is firmly fixed via the adapter 18 by the annular jaw portion 20a. It is configured to be coupled to the main body portion 16a.

Referring now to FIG. 3, in the embodiment shown in FIG. 3, the adapter 18 is omitted and the jaw portion 20a of the upper seat portion 20 is directly pressed against the head portion 12b of the fixing bracket element 12 from above. Thus, the fixing bracket element 12 is immovably and firmly held in the receiving hole 40 of the lower receiving portion 16. In this case, the upper seat portion 20 may adopt a design condition such as a slightly thicker shape as a whole in order to increase the rigidity of the jaw portion 20a. However, this embodiment is inferior to that of the above-described embodiment in terms of superiority to the conventional form described in Document 2 due to the omission of the adapter 18, and the function of the adapter 18 is compensated by the jaw portion 20a of the upper seat portion. In other words, it should be understood that the above-described embodiment is superior in terms of fixing and holding the fixing bracket element 12 and adaptability to changes in the dimensions and shape of the element 12.
It should be noted that the other structure shown in FIG. 3 may be the same as that shown in FIG. 2, and therefore, as in the embodiment shown in FIG. It is.

  4 is a cross-sectional view of a portion A of FIGS. 2 and 3, and as shown in detail in FIG. 4, the body portion 16a of the lower seat portion 16 of the seat 14 has an outer peripheral surface area (this example). Is a circular outer peripheral surface, but may be formed on the outer surface of the corner), and has a protruding claw 16c formed in a circumferential shape, and this protruding claw 16c is the inner surface of the peripheral portion of the upper seat portion 20. The upper and lower seat portions 16 and 20 are integrally fitted and joined together by engaging with the corresponding protruding claws 20c provided in 20b. In this case, both the projecting claws 16c and 20c form a coupling means. When the upper receiving part 20 is pressed and fitted from above toward the lower receiving part 16, the upper and lower receiving parts 16 are both connected. , 20 are combined to form an integrated seat 14, and at this time, the fixing bracket element 12 is firmly held via the adapter 18.

As is clear from the above description, the furniture cradle 10 of the present invention completes the assembly without using the fixing means such as the adhesive or the integral molding method for each of the separate parts 12, 14 (16 + 20) and 18. On the contrary, if the upper and lower seat portions 16 and 20 of the seat 14 are separated and separated, they are separated into separate parts again. As a result, for example, after the desired service life has elapsed, or for some reason, for example, when the lower seat 16 is damaged, or when the felt seat 16b is worn out or worn out, the furniture cradle 10 is temporarily removed. It was possible to remove it from the mating member, disassemble it, and replace it with a new part . And when exchanging and discarding, it becomes possible to sort and discard by material after disassembly and separation. Therefore, it can also contribute to the reuse of resources.
Further, the fixing bracket element 12 is replaced with a fixing bracket element 12 having a different size in accordance with the difference in the standard of the mating furniture legs, such as the thickness and shape , and a simple annular adapter 18 made of a single material. Can be dealt with by exchanging in response to the dimensional change of the metal fitting element 12, eliminating the inconvenience of forming all the parts with all new parts, and reducing the cost. It becomes.

  5 shows that the upper and lower seat portions 16 and 20 constituting the seat 14 are replaced by an example in which the coupling means is constituted by the projecting claws 16c and 20c shown in FIG. A male screw 16d is engraved on the outer peripheral surface of the main body portion 16a, and a corresponding female screw 20d is engraved on the inner peripheral surface 20b of the upper seat portion 20, and the upper and lower seat portions 16, 20 are fitted by screw connection. The case where it is set as the embodiment which couple | bonds is shown. In other words, preferably, the upper and lower receiving parts 16 and 20 are joined by fitting and joining of the protruding claws to form the receiving seat 14, but it should be understood that the invention is not limited to the coupling means using the protruding claws. It is what was presented. In the illustrated example, the protruding claws are a pair, but if necessary, two protruding claws can be formed on both to be firmly coupled.
