Description

  The present invention relates to a socket that can be preferably used when a rod-shaped member such as a hanger pipe used in clothes dance, closet, or the like is installed between opposing wall surfaces.

  When a hollow or solid bar-like member is installed between two opposing wall surfaces, a socket (also called a cap socket or the like) that supports the end of the bar-like member is used.

  6 (A) to 6 (C) are cross-sectional views sequentially showing a construction procedure when a rod-like member is installed between opposing wall surfaces using a conventional socket. Since the support method of the rod-shaped member is the same at both ends, in FIGS. 6A to 6C, only one end portion of the rod-shaped member is shown in order to simplify the drawing.

  First, as shown in FIG. 6A, a disk-shaped pedestal 910 is fixed on the wall surface 70 using a main screw 991 and an auxiliary screw 992. The main screw 991 passes through the center of the pedestal 910, and the auxiliary screw 992 passes through a position off the center of the pedestal 910. A male screw 911 is formed on the outer peripheral surface of the base 910.

  Next, as shown in FIG. 6B, the end surface of the rod-shaped member 60 that penetrates the socket body 940 is brought into contact with the main surface of the base 910. The socket body 940 has a substantially cylindrical shape, and a female screw 941 is formed on the inner peripheral surface on one end side thereof. The socket main body 940 is moved to the base 910 side, and the female screw 941 of the socket main body 940 and the male screw 911 of the base 910 are screwed together.

  Thus, as shown in FIG. 6C, one end of the rod-shaped member 60 can be held on the wall surface 70 via the socket 900 including the base 910 and the socket body 940. The same operation as described above is performed on the other end of the rod-shaped member 60.

  According to such a conventional socket 900, the rod-like member 60 can be installed between a pair of opposing wall surfaces, and the female screw 941 of the socket main body 940 and the pedestal can be removed without removing the screws 991, 992 from the wall surface 70. The rod-shaped member 60 can also be removed by releasing the screwing with the male screw 911 of 910.

  However, in order to mount the rod-shaped member 60 on the wall surface 70 using the conventional socket 900, the end surface of the rod-shaped member 60 is in contact with the main surface of the pedestal 910 as shown in FIG. The female screw 941 of the socket body 940 and the male screw 911 of the base 910 must be screwed together. That is, a certain amount of time is required to screw the female screw 941 and the male screw 911 together. In addition, the rod-shaped member 60 must be held during that time.

  Further, when removing the installed rod-shaped member 60 from the wall surface 70, a certain amount of time is required to release the screwing between the female screw 941 of the socket main body 940 and the male screw 911 of the base 910. The member 60 must continue to be held.

  The above problems are particularly serious when the rod-shaped member 60 is heavy or when working alone. Further, the operation of rotating the socket main body 940 to screw the female screw 941 and the male screw 911 or release the screwing may be burdensome for elderly people.

  An object of this invention is to provide the socket which can simplify and shorten the operation | work at the time of hold | maintaining a rod-shaped member on a wall surface.

  The socket according to the present invention includes a seat portion fixed to a wall surface, a pedestal having a receiving portion that is erected on the seat portion and on which an end portion of the rod-like member is placed, and a substantially cylindrical member into which the rod-like member is inserted And an elastic member fixed to one of the outer peripheral surface of the seat portion and the inner peripheral surface of the socket main body. And when the said base is inserted in the said socket main body, the said socket main body is hold | maintained at the said base via the said elastic member, It is characterized by the above-mentioned.

  According to the present invention, the rod-shaped member can be held on the wall surface easily and in a short time.

  In the socket of the present invention, a fitting protrusion formed so as to project a part of the outer peripheral surface of the end of the rod-shaped member is formed on the inner peripheral surface of the socket main body. When the pedestal is inserted into the socket main body so as to be held by the pedestal via the elastic member, the fitting protrusion is arranged within a range where the receiving portion does not exist in the circumferential direction of the rod-shaped member. It is preferable. Thus, even when an external force such as an upward or lateral direction acts on the rod-shaped member in a state where the pedestal is inserted into the socket body, the rod-shaped member can be prevented from being largely displaced in the socket body.

  In this case, when the pedestal is inserted into the socket body, it is preferable that the receiving portion and the fitting protrusion surround substantially the entire range in the circumferential direction of the rod-shaped member. Thereby, a rod-shaped member can be fixed more firmly with little rattling. Here, “surrounding substantially the entire range in the circumferential direction of the rod-shaped member” preferably means 80% or more, further 90% or more of the outer circumferential length of the rod-shaped member.

  Preferably, the elastic member is an O-ring, and the O-ring is fitted in a circumferentially continuous groove formed on the outer peripheral surface of the seat portion. As a result, the elastic member can be mounted simply by inserting a widely used O-ring into the groove, so that a socket that is easy to manufacture and low in cost can be provided.

  The present invention will be described in detail below with reference to preferred embodiments. However, it goes without saying that the present invention is not limited to the following embodiments.

  A socket 1 according to an embodiment of the present invention includes a base 10 shown in FIG. 1, an O-ring 50 as an elastic member, and a socket body 40 shown in FIG. 2. For ease of understanding, when the socket 1 is mounted on a wall surface parallel to the vertical direction, the vertical axis is the Z axis, the horizontal axis perpendicular to the wall surface is the X axis, the Z axis and the X axis are perpendicular to each other. The horizontal axis is the Y axis. In the figure, the direction of the arrow on the Z axis indicates the upper side, and the direction of the arrow on the X axis indicates the wall surface side.

  As shown in FIG. 1, the pedestal 10 includes a substantially disk-shaped seat portion 20 and a receiving portion 30 erected on one main surface of the seat portion 20.

  Screw holes 21 and 22 for inserting screws for fixing the pedestal 10 to the wall surface are respectively formed at the center of the seat portion 20 and at positions away from the center. A circumferentially continuous groove 25 is formed on the outer peripheral surface, which is a substantially cylindrical surface of the seat portion 20. An O-ring 50 is fitted in the groove 25 (see FIG. 4A described later).

The receiving part 30 is a portion above the horizontal plane including the central axis 2 from a cylindrical body having the central axis 2 of the socket 1 (that is, an axis passing through the center of the seat part 20 and parallel to the X axis) 2 as a central axis. It has a shape similar to the removed semi-cylindrical body. In a cross section perpendicular to the central axis 2, the radius of curvature of the arc formed by the receiving surface 31 facing the upper side of the receiving portion 30 is R ₃₁ , and the radius of curvature of the arc formed by the back surface 32 facing the lower side is R ₃₂ . The curvature radius R ₃₁ is preferably set to a value that is substantially the same as or slightly larger than the curvature radius of the outer cylindrical surface of the rod-shaped member supported by the socket 1. The curvature radius R ₃₂ is preferably set to a value that is substantially the same as or smaller than the radius of the outer peripheral surface of the seat portion 20.

  The socket body 40 includes an outer cylinder 41 having a substantially cylindrical shape, and a fitting protrusion 42 formed so as to protrude from the inner peripheral surface of the outer cylinder 41.

  3A is a cross-sectional view along the vertical plane including the central axis of the socket body 40 (ie, the central axis 2 of the socket 1), and FIGS. 3B and 3C are respectively the same as FIG. It is arrow sectional drawing along the 3B-3B line | wire and 3C-3C line | wire of A).

The fitting protrusion 42 has a shape approximate to a semi-cylindrical body obtained by removing a portion on one side of the surface including the central axis 2 from the cylindrical body having the central axis 2 as a central axis. In the cross section perpendicular to the central axis 2, when the curvature radius of the inner peripheral surface of the fitting protrusion 42 is R ₄₂ , the curvature radius R ₄₂ is substantially equal to the curvature radius of the cylindrical surface outside the rod-shaped member supported by the socket 1. It is preferably set to the same value or slightly larger than this, and is preferably substantially the same as the radius of curvature R ₃₁ of the receiving surface 31 of the receiving portion 30. The fitting protrusion 42 is not formed in the range of the distance D from the wall side end (X-axis arrow side end) of the socket body 42. The distance D is preferably equal to or greater than the thickness of the seat portion 20 of the base 10 in the X-axis direction.

Of the inner peripheral surface of the outer cylinder 41, the radius of curvature of the region fitting protrusion 42 is not formed when the R _41, the radius of curvature R ₄₁ is the radius of curvature R ₃₂ of the back 32 of the receiving part 30 of the pedestal 10 and It is preferably slightly larger than the radius of the outer peripheral surface of the seat portion 20.

A decorative plate 43 that protrudes inward is formed in a region of the end opposite to the wall of the socket body 42 (the end opposite to the X-axis arrow) where the fitting protrusion 42 is not formed. ing. As shown in FIGS. 3B and 3C, the inner peripheral edge of the decorative plate 43 forms an arc having a curvature radius R ₄₂ that is continuous with the inner peripheral surface of the fitting protrusion 42. It is preferable.

  An example of a construction procedure for constructing a rod-shaped member between opposing wall surfaces using the socket 1 according to the present embodiment configured as described above will be described with reference to FIGS. 4 (A) to 4 (C). Since the support method of the rod-shaped member is the same at both ends, in FIGS. 4A to 4C, only one end portion of the rod-shaped member is shown in order to simplify the drawing.

  First, the O-ring 50 is fitted into the groove 25 on the outer peripheral surface of the seat portion 20 of the base 10. Then, as shown in FIG. 4A, the main screw 91 and the auxiliary screw 92 are used with the pedestal 10 on one opposing wall surface 70 so that the receiving surface 31 of the receiving portion 30 faces upward. And fix. The main screw 91 is inserted into the screw hole 21 and mainly supports a load of a rod-shaped member 60 described later. The auxiliary screw 992 is inserted into the screw hole 22 and mainly prevents the base 10 from rotating around the main screw 91. Similarly, the base 10 is fixed to the other wall surface.

  Next, as shown in FIG. 4B, one end of the rod-shaped member 60 that penetrates the socket body 40 is placed on the receiving surface 31 of the receiving portion 30 of the base 10. Similarly, the other end portion of the rod-shaped member 60 that penetrates the socket body 40 is placed on the base 10 fixed to the other wall surface.

  Thereafter, the socket body 40 is moved to the wall surface 70 side. The base 10 is inserted into the socket body 40 by adjusting the rotational position of the socket body 40 in the outer peripheral direction of the rod-shaped member 60 so that the fitting protrusion 42 in the socket body 40 does not collide with the receiving portion 30 of the base 10. To do. The O-ring 50 attached to the outer peripheral surface of the seat portion 20 abuts on the inner peripheral surface of the outer cylinder 41 of the socket main body 40 and is elastically compressed and deformed, and is inserted into the socket main body 40. As shown in FIG. 4C, the socket body 40 is held on the base 10 via the O-ring 50. At this time, the socket body 40 is firmly fixed to the base 10 by the frictional force generated between the inner peripheral surface of the outer cylinder 41 and the O-ring 50.

  As shown in FIG. 5, which is a cross-sectional view taken along line 5-5 in FIG. 4C, the fitting protrusion 42 is arranged in a range where the receiving portion 30 does not exist in the circumferential direction of the rod-shaped member 60. Has been. The receiving portion 30 and the fitting protrusion 42 surround almost the entire range of the rod-shaped member 60 in the circumferential direction. As a result, the end of the rod-shaped member 60 is firmly held by the receiving portion 30 or the fitting protrusion 42 regardless of the upward or lateral force applied to the rod-shaped member 60 other than downward.

  As described above, according to the socket 1 according to the present embodiment, the pedestal 10 fixed to the wall surface 70 includes the receiving portion 30 on which the end of the rod-shaped member 60 can be placed. It is not necessary to hold the rod-shaped member 60 during the work of inserting the base 10 into the 40. Therefore, the burden on the operator is reduced.

  Furthermore, the mounting operation of the socket body 40 on the base 10 is performed by slightly rotating the socket body 40 around the rod-shaped member 60 so that the fitting protrusion 42 in the socket body 40 does not collide with the receiving portion 30 of the base 10. After that, the socket body 40 is completed simply by translating along the longitudinal direction of the rod-shaped member 60 so as to cover the O-ring 50 mounted on the base 10. That is, unlike the conventional socket 900 shown in FIGS. 6 (A) to 6 (C), there is no need to rotate the socket body 940 a plurality of times in order to screw the screws. Therefore, the construction work of the rod-shaped member 60 is completed extremely easily and in a short time.

  Further, when removing the erected rod-shaped member 60 from the wall surface 70, it is only necessary to pull out the socket body 40 from the base 10 with a force equal to or greater than the frictional force with the O-ring 50. At this time, it is not necessary to rotate the socket body 40 around the rod-shaped member 60. That is, unlike the conventional socket 900 shown in FIGS. 6A to 6C, there is no need to rotate the socket body 940 a plurality of times in order to release screwing. Therefore, the removal work of the rod-shaped member 60 is completed extremely easily and in a short time.

  Further, even after the socket body 40 is extracted from the pedestal 10, the rod-shaped member 60 is placed on the receiving portion 30 of the pedestal 10, so that the rod-shaped member 60 is held during the operation of extracting the socket body 40 from the pedestal 10. There is no need to be. Therefore, the burden on the operator is reduced.
