  Embodiments of the present invention will be described below with reference to the accompanying drawings. In the two embodiments described below, the main body portion and the lid portion are substantially semicircular so that the circular cross-section can be held, but various shapes such as a square cross-section are shown. Needless to say, a saddle support suitable for the shape can be applied.

  FIG. 1 is an explanatory view of a first embodiment of a heel support according to the present invention. FIG. 1 (a) is a plan view and a partially enlarged plan view showing a state in which a main body portion and a lid portion are opened, FIG. ) Is a plan view and a partially enlarged plan view showing the closed state, and FIG. 2 is a perspective view of the coffin support.

  The heel support 1 includes a main body portion 10 formed of a curved band body (substantially semicircular band body in the illustrated example) and a lid portion 20 similarly formed of a curved band body at one end 10a, 20a. The lid 20 can be opened and closed with the hinge 2 as a fulcrum, and the other end 10b of the main body 10 and the other end 20b of the lid 20 are locked and connected by the locking portion 3. Further, a fixing portion 4 for fixing to a wall surface or the like is formed on the outer surface side of the main body portion 10.

  In addition, 13 and 23 in a figure are the reinforcing ribs formed in the longitudinal direction of the curved strip. Reference numeral 14 denotes a pressing piece formed on the main body 10 that elastically presses the heel T held by the main body 10 and the lid 20 in the direction of the lid 20. Since the heel T is pressed and supported by the elastic biasing force of the pressing piece 14, it can be used for a plurality of types of ridges having slightly different diameters.

  And the heel support 1 fixes the fixing | fixed part 4 to a wall surface etc. in the state which hold | maintained the substantially circular cross-sectional ridge T between this main-body part 10 and the cover part 20, ２０T Support and fix. The fixing portion 4 is substantially L-shaped in the illustrated example, and the mounting piece 4a can be fixed to the wall surface or the like with a screw or the like, but may have other shapes and structures.

  On the other hand, the locking at the locking portion 3 by the main body portion 10 and the lid portion 20 is performed by the locking of the locking projections 11 and the locking pieces 21 provided at the other ends 10b and 20b.

The engaging pieces 21 is formed in a shape in plan view "V" by bending the free ends of the curved band constituting the lid 20 (the other end 20b), the shaped portion of the "V" The central bent portion 21c faces the curved band body, and the open end portion 21a and the base end portion 21b protrude outward in an oblique direction. In order to allow the base end portion 21b of the locking piece 21 to interlock with the locking convex portion 11 formed on the main body portion 10, two locking convex portions are provided at positions adjacent to the base end portion 21b. Two locking holes 22 (shown only in FIG. 2) for inserting 11 are formed. Not the locking hole 22 but a notch may be used.

  Moreover, the latching convex part 11 cuts out part of the free end (other end 10b) of the curved strip which comprises the main-body part 10, and is made into two-forked two pieces, and each is bent outward and curved shape ( The end face of the open end 11b, which is the terminal end of the locking projection 11, is located outside the curved band body, which is located in the vicinity of the bent base 11a of the locking projection 11. Close to the side (see FIG. 1). Note that the end surface of the open end portion 11b may contact the outer surface of the curved strip.

  A stepped portion 11 c is formed at the open end portion 11 b of the locking projection 11 so as to be bent in the inner direction of the circle formed by the locking projection 11. A recess is formed by the step portion 11c, and the recess is fitted into the base end portion 21b of the locking piece 21 when the locking projection 11 is inserted into the locking hole 22 of the lid portion 20. A locking recess 12 is formed.

  If the heel support 1 is closed in a state where the heel T is held, the elastic force of the pressing piece 14 of the main body portion 10 acts, and the locking portion 3 between the main body portion 10 and the lid portion 20 is moved from the inside. When both are pressed, a tensile force is generated in the opposite direction along the curved shape of the curved band body with the locking portion 3 as the center, and the base end portion 21b of the locking piece 21 is fitted deeply into the locking recess 12. It gets stuck and is locked by being caught by the step portion 11c.

  Thus, the locking piece 21 and the locking projection 11 are not only interlocked with the locking projection 11 protruding from the locking hole 22 but also the base end portion 21 b of the locking piece 21. Is inserted into the locking recess 12 and is locked by being hooked on the step portion 11c, so that the locking piece 21 slides on the curved outer surface of the locking projection 11 by impact or thermal expansion and contraction. Is not released and the lid 20 does not come off, so that the locking strength is improved. Further, since the base end portion 21b of the locking piece 21 is fitted into the locking recess 12 to lock the locking state, the protruding state of the locking projection 11 can be reduced, and as a result , Looks better.

  In this way, the base end portion 21b of the locking piece 21 is fitted into the locking recess 12 and locked. Further, as shown in the figure, the vicinity of the central bent portion 21c of the locking piece 21 is positioned near the main body portion 10. If it is made to contact the outer surface of the curved belt body, it can be fixed without rattling by the two-point support.

  When the lid 20 is opened, for example, the heel T is pushed in the direction of the hinge 2 from the vicinity of the locking portion 3 or is pushed in the direction of the main body 10 (pressing piece 14) from the lid 20 side. It is only necessary to release the lock by loosening the mutual pulling force between the portion 10 and the lid portion 20 and floating the base end portion 21b of the locking piece 21 from the locking recess 12, and in the state where the lock is released. If the open end 21a of the locking piece 21 is pulled outward, the locking can be easily released.

Next, a second embodiment (reference example) of the heel support according to the present invention will be described.

  3A and 3B are explanatory views of the embodiment. FIG. 3A is a plan view and a partially enlarged plan view showing a state where the main body and the lid are opened, and FIG. 3B is a plan view showing a closed state. FIG. 4 is a partially enlarged plan view, and FIG. 4 is a perspective view and a partially enlarged perspective view of the same support tool.

  The hook support 1 also has a structure in which the locking projection 11 of the main body portion 10 and the locking piece 21 of the lid portion 20 are locked and closed, but the bent locking projection 11 A locking recess 12 is formed in the open end portion 11b by means different from the first embodiment.

  That is, in this embodiment, a part of the open end portion 11b of the locking projection 11 is cut and raised, and the locking recess 12 is formed by the cut and raised piece 11d. In addition, in this embodiment, the latching convex part 11 and the latching recess 12 into which it is fitted are each formed, and it latches in one place.

  In addition, since the locking structure by fitting the locking piece 21 into the locking recess 12 is the same as that of the first embodiment, the same components are denoted by the same reference numerals, and the description thereof is omitted. . Of course, the effect is the same as that of the first embodiment.

  Unlike the step 11c (see FIG. 1) shown in the first embodiment, the locking recess 12 formed by the cut and raised piece 11d is slightly difficult to process, but once the cut and raised piece 11d is Once formed, the degree of the cut and raised can be easily adjusted, and the locking of the locking piece 21 with the base end portion 21b can be adjusted so that there is no rattling.

  In the above two embodiments, the fixing portion 4 is L-shaped, but it is also possible to provide a sharp portion with a sharp tip and to fix the sharp portion by driving it into the wall.

  Finally, another example of the locking projection 11 of the main body 10 of the heel support 1 will be described with reference to FIG. 5 (a) and 5 (b) are plan views of the locking convex portion, FIG. 5 (a) is another example in which the locking recess 12 is locked by the step portion 11c, and FIG. The other example at the time of forming the latching recess 12 by cutting and raising the piece 11d is shown. This example can be applied to both the first and second embodiments.

  5A, the free end (the other end 10b) of the curved strip is once bent outwardly into a hairpin shape and bent so that the locking recess 12 is formed. Further, it is formed by curving in the opposite direction (counterclockwise) from the step portion 11c.

  That is, the locking projection 11 shown in FIG. 5 (a) differs in formation method and shape, but the locking recess 12 by the step portion 11c is the locking projection, as in FIGS. 11 is formed in the vicinity of the bent base portion 11a, and the base end portion 21b (see FIG. 1) of the locking piece 21 can be locked there.

  5 (b) is curved in the opposite direction (counterclockwise) to that shown in FIGS. 3 and 4, and the bent base portion of the locking protrusion 11 is bent. A cut-and-raised piece 11d is formed on the curved base located in the vicinity of 11a, and a locking recess 12 is formed by the cut-and-raised piece 11d.

  As described above, the above two examples are different from the first and second embodiments in the method of forming the locking projections 11, but the locking recess 12 is formed at the same position, so the same effect is expected. it can.
