JP5736480B2 - Furniture leg cap - Google Patents

Description

  The present invention relates to a cap that is used by being fitted to a lower end portion of a leg of furniture such as a table or a chair, that is, a furniture leg cap.

  There are known caps that are used on the ends of furniture legs such as chair legs and table table legs. The cap is attached to the lower end of the leg so as not to damage the floor or the leg tip by dragging a chair or the like, or to prevent slipping so as not to move easily. As furniture with legs, various things such as a desk such as a study desk and a conference desk, a bed, and the like can be considered.

  As the former conventional example, a “furniture leg cover” disclosed in Patent Document 1 is known. This furniture leg cover is made of an ultra-soft resin such as silicon rubber, and an extrapolated portion (1) that fits on the tip of the leg, and a sliding made of a hard resin such as polyamide provided integrally on the bottom surface of the extrapolated portion. It consists of a bottom (2).

  As the latter conventional example, there is known “non-slip of furniture legs” disclosed in Patent Document 2. This is because the center part of the bottom wall of the bag body (A) made of rubber material protrudes downward and its bottom surface is made into a sliding surface made of a bottom μ material such as fluororesin, and the outer peripheral part of the bottom wall remains rubber material. It is configured as a non-slip surface. For example, in the case of a single chair, since it is light, the sliding surface (4) protruding downward of the bag (A) provided at the lower end of the leg is in contact with the floor, so that it can easily move such as changing the place. And when a human body or the like sits on a chair and becomes heavy, the sliding surface (4) is elastically crushed and the anti-slip surface (5) is in strong contact with the floor, and cannot easily move and stabilize. It is described that it can perform various functions.

  In the former prior art, it is described that the bottom of the leg cover for furniture is made of a hard resin that slides smoothly and the furniture such as a chair can move smoothly, but it does not want to be slipped, such as firmly locking It is unsuitable for usage. Therefore, there is inconvenience that usage is limited. In the latter prior art, the bottom structure of the bag covering the lower end of the leg makes it possible to automatically switch between two types of functions: a slippery state at light loads and a non-slip state at heavy loads. It has become.

  However, in the latter prior art, there is a problem in durability that the bottom wall is frequently elastically deformed and deformed as the load increases or decreases, and is easily broken early. In addition, it is not suitable when it is desired to prevent slipping with a light load, or when it is desired to move lightly even with a heavy load, and there is also an aspect that limits the use situation. As described above, any of the conventional leg caps for furniture cannot flexibly respond to various requests for making it slippery or difficult to slip depending on the use situation of the furniture and the intention of the user. There was room left.

  Embodiments of a leg cap for furniture according to the present invention will be described below with reference to the drawings.

[Example 1]
The furniture leg cap (hereinafter, simply referred to as “leg cap”) C according to the first embodiment is a bottomed cylindrical shape that can be fitted to the leg ends of furniture as shown in FIGS. And a cap base body 1 made of rubber (an example of an elastic material), and a hard synthetic resin grounding body 2 detachably attached to the lower end side (front end side) of the cap base body 1 via the support means 3, It is comprised by the circular thing by planar view which has the axial center P. FIG.

  As shown in FIGS. 1 to 6, the cap base 1 includes a bottom wall 4 on which furniture bases can be placed, an upper cylindrical side peripheral wall 5 that rises upward following the outer periphery of the bottom wall 4, and It is formed in a substantially rotating body having a boss cylinder wall 6 protruding downward from the bottom wall 4. The side peripheral wall 5 has an upper constricted cylindrical lower cylindrical part 5A, and an inner cylinder whose outer peripheral surface and both outer peripheral surfaces are formed in a saw-toothed jagged surface and whose diameter is reduced following the upper end of the lower cylindrical part 5A. Part (an example of an opening part) 5B. Since the upper cylindrical portion 5B has a jagged surface, it can be easily extended to a large diameter when a thick leg of furniture is inserted, and can be firmly elastically clamped by adapting the cross-sectional shape of the leg to a round, square or distorted shape. .

  The bottom wall 4 has a lower first bottom surface 4A having a star shape (see FIG. 3) in a plan view in which a square plane is formed by being shifted by 45 degrees around the axis P, and the first bottom surface 4A is disposed on the inner side. Are formed in a stepped wall having an upper second bottom surface 4B having a circular outer periphery inside the lower end of the side peripheral wall 5. The bottom wall 4a of the bottom wall 4 is integrally provided with a pile-shaped fastener portion 3A that is a component of the surface fastener 3 described later.

  The grounding body 2 is a substantially bottomed cylindrical member comprising a cover side wall 7 that can be fitted onto the boss cylindrical wall 6 and a grounding wall 8 having a convex curved bottom surface 8a. An annular placement surface 8b lowered one step and a top surface 8c for receiving the ring bottom surface 6a of the boss cylinder wall 6 are provided. The mounting surface 8b is integrally equipped with a hook-shaped fastener portion 3B which is a component of the surface fastener 3 described later. The bottom surface 8a may be a curved surface or a flat surface with a smaller curvature.

  The support means 3 includes a pile-shaped fastener portion 3A that is integrated with the bottom surface 4a of the cap base 1 by thermal fusion or the like, and a hook-shaped fastener portion 3B that is integrated with the mounting surface 8b of the grounding body 2 by adhesion or the like. It is an area fastener. That is, the support means 3 is a surface fastener that is disposed across the cap base 1 and the grounding body 2 in a state along the bottom surface 4 a of the cap base 1. When the cover side wall 7 is fitted onto the boss cylinder wall 6 and the grounding body 2 is fitted and mounted on the cap base 1 until the top surface 8c contacts the ring bottom surface 6a, the hook-shaped fastener portion 3B and the pile-shaped fastener portion 3A are formed. It is set so as to be pressed and to function as the surface fastener 3.

  The cap base 1 is for forcibly inserting and locking furniture, for example, a lower end portion of a leg 11 of a chair (not shown) as shown in FIG. The leg 11 shown in FIG. 7 has a square shape such as a square cross-section, and is fitted into the bottom side wall 4b. The leg bottom 11a is in contact with the first bottom surface 4A. Accordingly, the upper cylindrical portion 5B is elastically expanded from the original round shape to a square shape in which the circle is inscribed so that the leg 11 can be firmly clamped and held firmly. In the case of a leg having a diameter larger than that of the first bottom surface 4A, the upper cylindrical portion 5B is further elastically expanded and firmly clamped, and the leg bottom can be placed on the second bottom surface 4B and stably held. is there.

  Now, the leg cap C to be attached to the lower leg of the furniture is firmly attached and held by the elastic fitting of the narrowed upper cylindrical part 5B, and the lower part is made of a hard synthetic resin having a low friction coefficient. Since the grounding body 2 is equipped, the sliding is good, and even if the chair is dragged, the floor is hardly damaged and the chair can be dragged and moved easily. Since the surface fastener 3 has a strong resistance to peeling in the shearing direction, even if a strong force is applied to pull the cap base 1 and the grounding body 2 apart from each other by dragging or the like, the grounding It is unlikely that the body 2 is detached from the cap base 1.

  Then, by the cover side wall 7 and the boss cylinder wall 6, the concave / convex fitting portion 9 in which the cap base 1 and the grounding body 2 are fitted in the direction intersecting the bottom surface 4 a of the cap base 1 (orthogonal in the first embodiment). Have. The concave / convex fitting portion 9 has an auxiliary function of the support means 3 for detachably connecting the cap base 1 and the grounding body 2, making it difficult for the grounding body 2 to be detached from the cap base 1 and clean. It also contributes to improving the appearance as an appearance.

  Since the grounding body 2 can be attached to and detached from the cap base body 1, the grounding body 2 is replaced with a grounding body 2 that is formed of a material having a high coefficient of friction such as rubber and that is integrally equipped with the hook-shaped fastener portion 3B. Thus, it is possible to switch from a slip-capable leg cap to a non-slip-cap leg cap. In this case, since the cap base is the same and only the grounding body 2 can be replaced, the structure is simple, simple and convenient, and the sliding and anti-slip specifications are independent of the weight of furniture such as chairs. It is good that it can be changed.

  Further, as shown in FIG. 2 and the like, the upper cylindrical portion 5B has a jagged surface on both the outer surface 12 and the inner surface 13, and a convex jagged surface 12a that protrudes on the outer side of the outer surface 12 and a concave surface that is recessed on the outer side of the inner surface 13. 13a is located on the same radiation with respect to the axis P. As a result, the upper cylindrical portion 5B is a kind of a folded fold-like wall. In addition to the elongation due to the material being rubber, the structure is easily extended, and the leg 11 in a considerable range can be obtained. It can be inserted corresponding to the diameter and can be firmly elastically clamped.

[Example 2]
As shown in FIG. 8, the grounding body 2 may be of a sliding specification in which a felt f is integrally provided on the bottom surface of the grounding wall 8. For example, a configuration is conceivable in which the mounting surface 10 having a step is formed by denting the central portion of the flat bottom surface 8a, and the felt f is integrally provided on the mounting surface 10. That is, it is the leg cap C which has the grounding body 2 with felt.

[Another Example]
As the uneven fitting portion 9, a configuration in which, for example, the cover side wall 7 and the boss cylinder wall 6 are screwed together is also possible. The hook-and-loop fastener 3 may have a structure in which the hook-shaped fastener portion 3B is fixed to the cap base 1 and the pile-shaped fastener portion 3A is fixed to the grounding body 2.
