Description

[Technical field]

[0001] TECHNICAL FIELD The disclosure herein relates to chair leg covers and methods of installing and removing the chair leg covers.

[0002] There are known furniture leg parts that are attached to the legs of furniture such as chairs and tables to prevent the floor surface from being damaged when the furniture is placed on the floor. As an example of a furniture leg part, a flooring felt 100 that combines a felt 101 and an adhesive layer 102 as shown in Fig. 1 is known. Many types of flooring felt are sold online.

[0003] In flooring felt, an adhesive layer is placed between the felt and the legs, and the felt is attached to the legs by the adhesive force of the adhesive layer. However, if the felt and the legs are attached only by the adhesive layer, there is a problem that the felt is easily peeled off from the legs.

[0004] As another example of a part for a furniture leg, Patent Document 1 discloses a part for a furniture leg comprising a seat plate, a fixing bracket for fixing the seat plate to furniture, and a cap for covering the seat plate. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Utility Model Registration No. 3095781 Summary of the Invention [Problem to be solved by the invention]

[0006] The furniture leg part described in the above Patent Document 1 is fixed to the leg by driving a slender fixing metal fitting formed of a nail or a screw into the leg, as shown in FIG. 4 of the above Patent Document 1. Therefore, unlike the flooring felt shown in FIG. 1, the furniture leg part is less likely to come off the leg. However, in the furniture leg part described in Patent Document 1, only the fixing metal fitting has a fixing function to the leg. Therefore, in the furniture leg part described in Patent Document 1, the strength with which the furniture leg part is fixed to the leg changes depending on the length of the fixing metal fitting driven into the leg.

[0007] However, when the length of the fixing metal fitting is increased in order to improve the fixing strength of the furniture leg part, there is a problem that the fixing metal fitting is easily bent when it is driven into the leg. In addition, in order to minimize bending of the fixing metal fitting when it is driven, the user needs to hold the fixing metal fitting by hand so that it is approximately perpendicular to the leg and apply a driving force in the direction of the central axis of the fixing metal fitting. However, in this case, the part of the furniture leg part that comes into contact with the leg is only the tip of the fixing metal fitting, and the direction easily changes. Therefore, the user needs to apply a driving force while continuing to hold the furniture leg part so that the fixing metal fitting is approximately perpendicular to the leg, which causes a problem that the installation work of the furniture leg part becomes difficult.

[0008] The disclosure of this application is made to solve the above problems. The inventors have conducted intensive research and have newly discovered that (1) the components constituting the chair leg cover include a second double-sided adhesive member that is attached to the leg and a fixing member having a needle part that is driven into the leg, (2) by shortening the length of the needle part protruding from the second double-sided adhesive member, when the chair leg cover is placed on the leg, the needle part is prevented from tilting obliquely with respect to the leg, in other words, the needle part can be oriented nearly perpendicular to the leg, and the fixing member can be driven into the leg even when the chair leg cover is tilted, and (3) when the base member and the leg are bonded with the second double-sided adhesive member, the fixing member also functions as an anchor for reducing the lateral shear force associated with the second double-sided adhesive member.

[0009] That is, an object of the disclosure in this application is to provide a chair leg cover that is easy to attach to the legs, and a method for attaching and removing the chair leg cover. [Means for solving the problem]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0014] The chair leg cover disclosed in this application and the method of attaching and removing the chair leg cover are described in detail below. Note that the position, size, range, etc. of each component shown in the drawings may not represent the actual position, size, range, etc., in order to facilitate understanding. Therefore, the disclosure of this application is not necessarily limited to the position, size, range, etc., disclosed in the drawings.

[0015] In addition, in this specification, (1) A numerical range expressed using "~" means a range that includes the numerical values ​​before and after "~" as the lower and upper limits. (2) Numerical values, numerical ranges, and qualitative expressions (e.g., expressions such as "same" and "the same") indicate numerical values, numerical ranges, and properties that include errors generally accepted in the relevant technical field. (3) When describing something as "approximately ____ shaped," it includes not only the exact ____ shape, but also a shape that can be understood to be roughly ____ shaped. This is interpreted as:

[0016] (Embodiment of chair leg cover) The chair leg cover 1 according to the embodiment will be described with reference to Figs. 2 to 4. Fig. 2A is a schematic side view for explaining the components constituting the chair leg cover 1, showing the state in which the components are not assembled. Fig. 2B is a schematic cross-sectional view showing the state in which the components are assembled. Fig. 3 is a top view for explaining the outline of the base member. Fig. 4A is a schematic side view for explaining the angle α when the tip 42a of the needle part 42 and the second double-sided adhesive member 6 are arranged to abut against the leg part 7, and Fig. 4B is a schematic side view showing the state in which the chair leg cover 1 is attached to the leg part 7.

[0017] The chair leg cover 1 according to the embodiment includes a sliding member 2, a first double-sided adhesive member 3, a fixing member 4, a base member 5, and a second double-sided adhesive member 6.

[0018] The fixing member 4 includes a crocodile portion 41 and a needle portion 42.

[0019] In the example shown in FIG. 2, the base member 5 is (1) A first surface 51 facing the leg portion 7 of the chair and a second surface 52 opposite to the first surface 51, (2) A wall portion 53 is formed around the second surface 52, and the second surface 52 and the wall portion 53 form a slide member accommodating space 54 that accommodates a part of the slide member 2, (3) The second surface 52 is formed with a crocodile portion accommodating space 55 for accommodating the crocodile portion 41, (4) A needle portion accommodating space 56 is formed, which penetrates from the alligator portion accommodating space 55 to the first surface 51 and allows the needle portion 42 to protrude from the first surface 51. is.

[0020] It is preferable that the crocodile portion accommodating space 55 is designed so that the crocodile portion 41 and the second surface 52 are substantially flat when the fixing member 4 is inserted. It is also preferable that the needle portion accommodating space 56 is formed substantially in the center of the first surface 51 and the second surface 52.

[0021] 3, the outer periphery of the base member 5 is formed in a substantially circular shape. When the outer periphery of the base member 5 is formed in a substantially circular shape and the needle accommodating space 56 is formed in the substantially center of the first surface 51 and the second surface 52, the angle α when the chair leg cover 1 described later is placed on the leg 7 is constant regardless of the placement direction.

[0022] Alternatively, although not shown, the outer periphery of the base member 5 may be formed in a regular polygon such as a triangle, a quadrangle, a pentagon, a hexagon, a heptagon, an octagon, a nonagon, a decagon, an eleventh angle, or a dodecagon. Even when the outer periphery of the base member 5 is formed in a regular polygon, the angle α when any one side is arranged to abut against the leg 7 is constant. Furthermore, when the outer periphery of the base member 5 is a regular polygon, the outer periphery part that abuts against the leg 7 is longer than when it is circular, so that the position of the chair leg cover 1 is less likely to shift after the chair leg cover 1 is arranged on the leg 7. Therefore, the convenience of attaching the chair leg cover 1 to the leg 7 is improved. When the outer periphery of the base member 5 is a regular polygon, the wall part 53 is also formed in a regular polygon, and the outer periphery of the slide member 2 is also formed in a regular polygon. As mentioned above, it is preferable that the needle accommodating space 56 is formed approximately in the center of the first surface 51 and the second surface 52. Alternatively, however, the needle accommodating space 56 does not have to be formed approximately in the center of the first surface 51 and the second surface 52 as long as the angle α when the chair leg cover 1 is placed on the leg 7 is within the range described below.

[0023] 2 and 3, the outer periphery of the crocodile part 41 is formed in a substantially circular shape, and the inner edge of the crocodile part accommodating space 55 is also formed in a substantially circular shape. Alternatively, although not shown, the outer periphery of the crocodile part 41 and the inner edge of the crocodile part accommodating space 55 may be formed in a non-circular shape such as an ellipse or a polygon.

[0024] The slide member 2 includes a third surface 21 that is accommodated in the slide member accommodating space 54 and faces the second surface 52 of the base member 5, and a fourth surface 22 that protrudes from the slide member accommodating space 54 and abuts against the floor surface.

[0025] The first double-sided adhesive member 3 can be arranged to bond the second surface 52 of the base member 5 and the third surface 21 of the slide member 2 together.

[0026] The second double-sided adhesive member 6 can be arranged so that one surface is adhered to the first surface 51 of the base member 5 and the other surface is adhered to the leg portion 7. The shape and size of the second double-sided adhesive member 6 may be the same as or different from the first surface 51 of the base member 5, but it is preferable that they are the same from the viewpoint of obtaining a greater adhesive strength.

[0027] The length of the needle portion 42 is the length that protrudes from the second double-sided adhesive member 6 adhered to the first surface 51 of the base member 5 when the slide member 2, the first double-sided adhesive member 3, the fixing member 4, the base member 5, and the second double-sided adhesive member 6 are assembled.

[0028] As shown in FIG. 4A, when the components constituting the chair leg cover 1 are assembled and the tip 42a of the needle 42 and the second double-sided adhesive member 6 are arranged so as to abut against the leg 7, the angle formed between the needle 42 and the leg 7 is defined as α. The angle α may be expressed as the angle formed between the line connecting the tip 42a of the needle 42 and the end 61 (the part abutting against the leg 7) of the second double-sided adhesive member 6 and the central axis C1 of the needle 42. When the outer periphery of the base member 5 is a regular polygon, the end 61 of the second double-sided adhesive member 6 may be any side of the regular polygonal second double-sided adhesive member 6. If the angle α is too large, in other words, if the length of the needle 42 protruding from the second double-sided adhesive member 6 is too short, the needle 42 will not function as an anchor. Examples of the angle α include, but are not limited to, 84.3 degrees or less, 84 degrees or less, 83 degrees or less, 82 degrees or less, 81 degrees or less, 80 degrees or less, 79 degrees or less, 78 degrees or less, 77 degrees or less, 76 degrees or less, and 75 degrees or less. On the other hand, if the angle α is too small, the needle portion 42 is likely to bend when the chair leg cover 1 is driven into the leg portion 7. Examples of the angle α include, but are not limited to, 65.8 degrees or more, 66 degrees or more, 67 degrees or more, 68 degrees or more, 69 degrees or more, 70 degrees or more, 71 degrees or more, 72 degrees or more, 73 degrees or more, and 74 degrees or more. The angle α exemplified above is merely an example. For example, the angle α may be set based on any one or two decimal places selected from 65.8 degrees or more and 84.3 degrees or less.

[0029] The material for forming the sliding member 2 is not particularly limited as long as it is a material that will not be crushed even when a person sits on the chair to which the chair leg cover 1 is attached. Examples of the material include, but are not limited to, plastic materials such as fluororesin and polyurethane, rubber, wood, metal, and the like. The sliding member 2 may be formed of a single material or a combination of multiple materials. For example, a base material may be formed of any material, and a material having desired properties may be coated or attached onto the base material. For example, if the fourth surface 22 is formed by coating the base material with a material that is slippery on the floor surface, the chair leg cover 1 functions as a sliding member on the floor surface. On the other hand, if the fourth surface 22 is formed by coating a material that is not slippery on the floor surface, the chair leg cover 1 functions as a slide prevention member on the floor surface. In addition, examples of materials to be attached include felt and resin films such as fluororesin and polyurethane. Regarding the material to be attached, a desired material may be selected in consideration of the ease of slipping on the floor surface.

[0030] As described above, a part of the sliding member 2 (the part on the third surface 21 side) is accommodated in the sliding member accommodating space 54. Therefore, even if a force is applied to the sliding member 2 in the lateral direction (direction X substantially perpendicular to the central axis C2 of the leg as shown in FIG. 4B), the sliding member 2 will not go beyond the wall 53 of the base member 5 and become detached. Therefore, the first double-sided adhesive member 3 only needs to have at least an adhesive strength sufficient to prevent the sliding member 2 from falling off from the sliding member accommodating space 54 when the orientation of the chair leg cover 1 is changed. Although not limited thereto, the first double-sided adhesive member 3 may be a known double-sided adhesive tape such as an acrylic emulsion.

[0031] The fixing member 4 (the crocodile portion 41 and the needle portion 42) is preferably made of a metal material commonly used in the art. Metal materials commonly used in the art include, but are not limited to, steel, brass, stainless steel, etc. Furthermore, the fixing member 4 may be plated with nickel or the like as necessary.

[0032] The base member 5 is a member that receives the load when the chair is moved after the chair leg cover 1 is attached to the leg. Therefore, it is preferable that the base member 5 is made of a material having a relatively high hardness. Examples of the material include, but are not limited to, resins such as polycarbonate, acrylic resin, nylon, polyamide, and polyether ether ketone (PEEK).

[0033] The second double-sided adhesive member 6 has a function of fixing the chair leg cover 1 to the leg 7. Therefore, it is preferable that the material is capable of strongly adhering the first surface 52 of the chair leg cover 1 to the leg 7 even when a force is applied in the lateral direction X. Although not limited thereto, examples of the material forming the second double-sided adhesive member 6 include an acrylic emulsion-based adhesive, a rubber-based adhesive, and a silicone-based adhesive.

[0034] The chair leg cover 1 according to the embodiment has the following advantages. (Effect 1) By using the chair leg cover 1 disclosed in the present application, the needle 42 can be driven into the leg 7 even when the tip 42a of the needle 42 and the second double-sided adhesive member 6 are in contact with the leg 7, in other words, even if the direction of the central axis C1 of the needle 42 deviates from the substantially vertical direction. Therefore, when attaching the chair leg cover 1 to the leg 7, the user does not need to hold the needle 42 so that it is substantially perpendicular to the leg 7, and can apply the driving force P with the needle 42 and the second double-sided adhesive member 6 in contact with the leg 7. This significantly improves the convenience of the attachment work. (Effect 2) The chair leg cover 1 disclosed in the present application is fixed to the leg 7 by a part of the needle part 42 driven into the leg 7 and by the second double-sided adhesive member 6. Therefore, when the chair leg cover 1 is fixed to the leg 7 with a desired force, the needle part 42 can be made shorter than when the chair leg cover 1 is fixed only by the needle part 42, and therefore there is less risk of the needle part 42 bending when the chair leg cover 1 is fixed to the leg 7. (Effect 3) The anchor effect of the needle part 42 will be described with reference to FIG. 5. For ease of understanding, the chair leg cover 1 shown in FIG. 5 has been omitted from its configuration that is unnecessary for the description of the anchor effect. As shown in FIG. 5A, it is assumed that the base member 5 and the leg part 7 are fixed by the second double-sided adhesive member 6 without using the fixing member 4. In this case, as shown in FIG. 5B, when a force (shear force) in the lateral direction X is applied to the second double-sided adhesive member 6, the second double-sided adhesive member 6 is displaced. As a result, a shear force is also applied to the adhesive surface between the second double-sided adhesive member 6 and the base member 5 and / or the adhesive surface between the second double-sided adhesive member 6 and the leg part 7, and the adhesive surfaces are easily peeled off. On the other hand, as shown in FIG. 5C, in the chair leg cover 1 according to the embodiment, the needle part 42 of the fixing member 4 is driven into the leg part 7 while penetrating the second double-sided adhesive member 6. Therefore, even if a force in the lateral direction X is applied, the second double-sided adhesive member 6 is less likely to be displaced in the lateral direction, unlike the example shown in FIG. 5B. As a result, even if the characteristics of the second double-sided adhesive member 6 shown in FIG. 5B and FIG. 5C are exactly the same, the shear force of the adhesive surface between the second double-sided adhesive member 6 and the base member 5 and / or the adhesive surface between the second double-sided adhesive member 6 and the leg portion 7 in FIG. 5C is smaller, and the adhesive surface is less likely to peel off. As described above, the needle portion 42 of the chair leg cover 1 according to the embodiment synergistically exerts different functions, namely, the fixing function of fixing the chair leg cover 1 to the leg portion 7 and the anchor function of reducing the shear force of the second double-sided adhesive member 6. Since the needle portion 42 is designed to be shorter than the conventional one, the fixing effect of the needle portion 42 alone is smaller than the conventional one, but the fixing effect of the second double-sided adhesive member 6 is significantly improved due to the anchor effect, and the chair leg cover 1 can be firmly fixed to the leg portion 7. In other words, the chair leg cover 1 according to the embodiment can obtain a significant synergistic effect by combining the needle portion 42 and the second double-sided adhesive member 6 arranged so that the needle portion 42 penetrates therethrough, compared to the case where each is used alone.

[0035] (Optional configuration example in which chair leg cover 1 can be adopted) Next, an optional configuration example in which the chair leg cover 1 can be used will be described with reference to Fig. 6. Fig. 6 is a schematic side view showing the state in which the chair leg cover 1 is attached to the leg 7.

[0036] A cutout 57 for inserting a removal member 8 for the chair leg cover 1 may be formed on the outer periphery of the first surface 51 of the base member 5 of the chair leg cover 1. The removal member 8 is not particularly limited as long as it has a thin, approximately flat tip, and may be, for example, a flat-head screwdriver. The size of the cutout 57 is not particularly limited as long as the chair leg cover 1 can be removed from the leg 7 by inserting a known flat-head screwdriver and applying force using the principle of leverage. The width of the tip of a flat-head screwdriver is 0.6 mm to 1.2 mm according to the JIS standard. Therefore, the cutout 57 may be formed so that a gap of about 1.5 mm is generated between the leg 7 and the chair leg cover 1 when the chair leg cover 1 is attached to the leg 7. Although not limited, the cutout may be formed in the outer periphery of the first surface 51 toward the second surface 52 so that the depth is about (1.5-a) mm, assuming that the thickness of the second double-sided adhesive member 6 is a (mm). Of course, it may be shorter than (1.5-a) mm. Furthermore, the depth of cutout portion 57 from the outer circumferential surface of base member 5 toward the center is not particularly limited as long as it is within a range that allows sufficient insertion of removal member 8. Although not limited thereto, it may be, for example, about 1 mm to 2 mm.

[0037] When the chair leg cover 1 has the cutout portion 57, the chair leg cover 1 attached to the leg portion 7 can be easily removed.

[0038] The chair leg cover 1 according to the embodiment described above and the optional additional configuration example show one example of the chair leg cover 1, and are not limited to the described examples. Other configurations may be added or deleted within the scope of the technical idea disclosed in this application. For example, in the example shown in FIG. 2, the fixing member 4 is formed of the crocodile portion 41 and the needle portion 42. Alternatively, the fixing member 4 may be formed only of the needle portion 42, and the portion opposite to the tip 42a of the needle portion 42 may be fixed to the needle portion accommodating space 56 of the base member 5. In that case, the crocodile portion accommodating space 55 may not be formed, and the needle portion accommodating space 56 may have at least a protruding hole formed on the first surface 51 side so that the needle portion 42 can protrude from the first surface 51, and the needle portion accommodating space 56 may be formed to penetrate to the second surface 52, or may not penetrate.

[0039] (Embodiment of mounting method) Next, an installation method according to an embodiment will be described with reference to Fig. 4. The installation method is carried out using the chair leg cover 1 according to the embodiment described above and any of the optional configuration examples thereof.

[0040] The installation method is (1) a placement step of placing the chair leg cover 1 so that the tip 42a of the needle portion 42 and the second double-sided adhesive member 6 abut against the leg portion 7 (see FIG. 4A ); (2) A chair leg cover attachment step of attaching the chair leg cover 1 to the leg 7 by pressing P the chair leg cover 1 arranged in the arrangement step toward the leg 7 (see Figs. 4A and 4B).

[0041] The attachment method provides the same advantages as (Advantage 1) and (Advantage 2) provided by the chair leg cover 1 according to the above-described embodiment.

[0042] (Embodiment of Removal Method) Next, a removal method according to the embodiment will be described with reference to Fig. 6. The removal method is carried out after the above-mentioned attachment method is carried out using the chair leg cover 1 having the above-mentioned cutout portion 57.

[0043] The removal method is (1) an engagement step of engaging the removal member 8 with the cutout portion 57 of the chair leg cover 1 (see FIG. 6 ); (2) a removal step of removing the chair leg cover 1 from the leg 7 by operating a removal member 8; Although the removal process is not shown in the drawings, the chair leg cover 1 can be removed from the leg 7 by twisting a removal member 8 such as a flat head screwdriver or by using the principle of leverage.

[0044] As for the removal method, since the chair leg cover 1 is provided with the cutout portion 57, the chair leg cover 1 attached to the leg portion 7 can be easily removed.

[0045] The following examples are provided to specifically explain the embodiments disclosed in the present application, but these examples are merely for the purpose of explaining the embodiments and are not intended to limit or restrict the scope of the invention disclosed in the present application.

[0046] <Example 1> The chair leg cover 1 was made using the following materials. (1) Slide member A polyurethane resin was used as the base material, and a fluorine film was attached to the surface. (2) Fixing member The diameter of the crocodile portion 41 was 10.9 mm, and the thickness of the needle portion 42 was 0.9 mm. The material used was a steel wire that was nickel-plated. Two types of fixing members were produced with different lengths of needle portion 42 so that the lengths of needle portion 42 protruding from the second double-sided adhesive member 6 when assembled were 1 mm and 4.5 mm. (3) Base material The second surface 52 was made of polycarbonate and had a wall 53 having a height of 1.8 mm around the second surface 52. (4) First double-sided adhesive member and second double-sided adhesive member An acrylic emulsion adhesive was used, with a thickness of 0.8 mm.

[0047] The produced chair leg cover 1 is shown in Figure 7. The top part of Figure 7 shows, from the left, the sliding member, the fixing member, the base member, and the first and second double-sided adhesive members. The bottom part of Figure 7 shows the chair leg cover 1 assembled from each member.

[0048] <Example 2> The chair leg cover 1 produced in Example 1 was placed on wood (ash wood). Figure 8A is a photograph of the chair leg cover 1 with the needles 42 protruding from the second adhesive member 6 having a length of 1 mm. Since the diameter of the second double-sided adhesive member 6 is 20 mm, the angle α is 84.3 degrees when the needles 42 protruding from the second adhesive member 6 have a length of 1 mm. Figure 9A is a photograph of the chair leg cover 1 with the needles 42 protruding from the second adhesive member 6 having a length of 4.5 mm, and the angle α is 65.8 degrees.

[0049] Next, when a pressing force was applied from above to the chair leg cover 1 shown in Figs. 8A and 9A by hand, the needle portion 42 could be driven into the wood without bending, as shown in Figs. 8B and 9B.

[0050] <Example 3> Next, an experiment was conducted to examine the effect of the chair leg cover 1 driven into the wood against the lateral load. FIG. 10 shows an outline of the experiment. First, as shown in FIG. 10A, the chair leg cover 1 (angle α is 65.8 degrees and 84.3 degrees) made in Example 1 was driven into the wood (ash wood). Next, as shown in FIG. 10B, the chair leg cover 1 was set so as to be positioned in the hole of the tensile metal plate, and set in a tensile tester. Using the tensile tester, a load was applied so that the chair leg cover 1 could move relatively in the lateral direction with respect to the wood. In Example 3, the load (maximum load (N)) when the chair leg cover 1 peeled off from the wood and the amount of displacement (amount of lateral displacement of the second double-sided adhesive member) when a load of 60 N was applied were measured. It should be noted that 60 N corresponds to the force when a chair is displaced 50 cm per second with a force of 120 kg. As a comparative example, a chair leg cover without assembled fixing members (i.e., needle part is 0 mm) was used.

[0051] The experimental results are shown in Table 1. [Table 1]

[0052] As is clear from the results in Table 1, the longer the needle, the larger the maximum load. From these results, it was confirmed that the needle is driven into the wood, making the chair leg cover less likely to fall off the wood. On the other hand, even when the needle protrudes only 1 mm, the displacement of 60 N was 1 / 5 or less compared to the case without the needle. The small displacement means that the second double-sided adhesive member 6 is less displaced in the lateral direction, in other words, even if a large lateral load is applied when the chair leg cover is in use, the chair leg cover is less likely to fall off the leg and functions effectively.

[0053] From the above results, it has been confirmed that the chair leg cover disclosed in the present application, by setting the length of the needle portion protruding from the second double-sided adhesive member to a predetermined length, simultaneously performs the following functions: (1) a fixing function that allows the cover to be easily driven into wood without bending and makes it difficult for the cover to fall off from the wood, and (2) an anchor function that prevents the second double-sided adhesive member 6 from shifting laterally.

[0054] In addition, the chair leg cover 1 produced in the embodiment has a cutout (the distance between the base member 5 and the wood is about 1.5 mm, and the depth toward the center is about 1.5 mm) as shown in Fig. 6. It was confirmed that the chair leg cover can be easily removed from the wood by inserting a flathead screwdriver into the cutout. [Industrial Applicability]

[0055] The chair leg cover disclosed in the present application can be easily attached to the legs of chairs and is not easily removed from the legs, and is therefore useful in the furniture industry. [Explanation of symbols]
