  Although the massage means of an Example is a well-known thing with an airbag, it is not limited to this.

  As shown in FIGS. 3 and 4, second rail portions (3 a) and (3 a) on which the first slide member (4) of the base portion (2) is fitted are provided on the left and right of the rear end of the main body portion (1). Is formed. The second rail portion (3a) is a hollow body having a rectangular cross section curved outward in an arc shape, and a narrow slit (31a) along the longitudinal direction is formed on the rear surface side.

  The centers of curvature of the second rail portion (3a) and the first rail portion (3) on the base portion (2) are located coaxially.

  In addition, brackets (21a) and (21a) project downward from the center left and right of the main body (1) in the front-rear direction, and the second ends of the base (2) are provided at the tips of the brackets (21a) and (21a). The second slide members (4a) and (4a) that fit into the one rail portions (3) and (3) are pivotally supported.

  In the embodiment, the first rail portion (3) (3) and the second rail portion (3a) (3a) have the same cross-sectional shape and correspond to the reclining range of the main body portion (1). The two slide members (4) and (4a) have a circular arc length of 90 ° to 120 ° so that they can be slidably guided, and are arranged with their positions shifted forward and backward.

  5 and 6 show the first slide member (4), the second slide member (4a) has the same shape.

The first slide member (4) is integrally formed of synthetic resin. The first slide member (4) has sliding contact portions (42) (42) at both ends of a shaft body (41) rotatably supported by the bracket (21).
It has.

  The outline of the sliding contact portion (42) has a substantially rectangular shape with four rounded corners, and the front and back sides along both sides along the longitudinal direction (along the longitudinal direction of the rail portion (3) (3a)). A long hole (44)) penetrating into the long hole (44) is established, and both ends of the long hole (44) are bent slightly along the short side of the sliding contact portion (42).

  On the outer surface of the sliding contact portion (42), a plurality of recessed portions (45) that do not penetrate the back surface are provided. The concave portion (45) has a role of preventing surface deformation due to “sink” during molding and has a meaning of saving resin.

  The central part of the side along the longitudinal direction of the sliding contact part (42) swells slightly higher to form a pressing piece (43) (43) that stretches against the inner surface of the second rail part (3a).

  Of the two sides along the longitudinal direction of the sliding contact portion (42), a long hole (44) is opened only inside one side, and an elastically deforming pressing piece (43) is provided only on one side. Also good.

  However, the first slide member (4) (4) on the base part (2) is moved to the second rail part (3a) (3a) of the main body part (1), and the second slide member (1) on the main body part (1) ( 4a) and (4a) are forcibly fitted into the first rail portions (3) and (3) on the base portion (2) from the end portions of the rail portions, respectively.

  The pressing pieces (43) and (43) of the first and second slide members (4) and (4a) are elastically deformed so as to narrow the hole width of the long hole (44), whereby the first and second slide members ( 4) (4a) can be inserted. However, due to the elastic restoring force of the pressing pieces (43) and (43), the first and second slide members (4) and (4a) are always against the inner surfaces of the first and second rail portions (3) and (3a). Since it is in a tension state, it will not slide unless a strong force is applied.

  That is, unless the main body part (1) is forcibly tilted with respect to the base part (2), the reclining angle of the main body part (1) is maintained. The reclining posture of the main body (1) does not change as long as the feet are placed on the main body (1).

  Therefore, when the main body portion (1) is set to a desired tilt posture, it is possible to receive a foot massage while maintaining the posture.

  To change the tilting posture of the main body (1), slide the sliding members (4) and (4a) in the rails (3) and (3a) by overcoming the tension of the sliding members (4) and (4a). Just do it.

  The subject receives a massage with the toe inserted into the concave receiving part (11) of the main body (1) and the calf inserted into the leg receiving part (12). The posture of the part (1) can be changed in the standing direction, and when the leg receiving part (12) is pushed downward with a strong force with the calf, the posture of the main body part (1) can be changed in the tilted direction. Therefore, the reclining posture of the main body (1) can be changed to a desired posture without interrupting the massage.

  Since the rail part (3) (3a) and the slide member (4) (4a) are engaged in two places on the left and right sides of the main body part (1), the reclining operation of the main body part (1) is stable. Can be done.

  8 and 9 show different aspects of the first embodiment.

It is equipped with a leaf spring (50) that urges it in the A direction). The leaf spring (50) is made of a stainless steel plate, and its both end portions (51) and (51) are bent outward and locked to both end bent portions (44a) of the long hole (44).

  The pressing piece (43) may vary in elasticity due to variations during molding, and the force for urging the pressing piece (43) outward may be weakened. In addition, if an overload is applied for a long time, a creep phenomenon may occur and the spring characteristics may be lost.

  However, since the pressing piece (43) is always urged by the leaf spring (50) toward the outside, that is, the inner surface of the rail portion (3) (3a), it is stable even if the spring characteristics are lost. Spring characteristics can be secured. Therefore, when the main body (1) is reclining, the holding force at an arbitrary angle is stabilized and can be stopped at an arbitrary angle. Durability is also improved.

And, the leaf spring (50) is simply attached to the long hole (44) because the bent portions (51) at both ends are merely locked to the bent portions (44a) at both ends of the long hole (44). be able to. It is.
FIGS. 10 to 15 show another example of the first and second slide members (4) and (4a), which are other embodiments of the first invention.

A notch (46) and (46) are provided substantially in parallel with the diameter line and symmetrically with respect to the diameter line, and an outer portion is formed as a pressing piece (43) from the notch (46).

  When the sliding contact part (42) is forcibly fitted into the rail part (3) (3a) so that the pressing piece (43) (43) hits the inner surface of the rail part (3) (3a), the notch (46) (46 The pressing pieces (43) and (43) are elastically deformed so as to close. Due to the elastic restoring force of the pressing pieces (43) and (43), the first and second slide members (4) and (4a) are always stretched against the inner surfaces of the first and second rail portions (3) and (3a). Therefore, it will not slide unless a strong force is applied.

  Further, in the above state, the slide contact portion (42) of the slide member (4) (4a) is broken in the circular shape and stretched by the pressing piece (43), so the slide contact portion (42) is in the rail portion (3) (3a). Can be prevented from rotating.

  In the embodiment of FIG. 10, a similar pressing piece is further formed between the pressing pieces (43) and (43) at the outer peripheral portion of the sliding contact portion (42), and four pressing pieces (43 ) Can be provided. In this case, even if the slide member (4) (4a) rotates in the rail part (3) (3a), the next pressing piece in the rotation direction works and stops the rotation at 90 °. Can do.

  13a and 13b show a third embodiment, which has a circular recess (421) at the outer end of the sliding contact portions (42) and (42) of the circular slide members (4) and (4a). A pressing piece (43) separate from both sliding contact portions (42) is fitted into the recess (421), and the pressing piece (43) is urged outward by a spring (47) to provide the rail portion (3). Stretch to the inner surface of (3a).

  The spring (47) is a disc spring, but is not limited to this, and the shaft (41) of the slide member (4) (4a) is hollow, and a compression spring is accommodated in the shaft (41) and pressed. The piece (43) can also be biased outward.

  It should be noted that the pressing piece (43) may be provided with only one sliding contact portion (42) out of the sliding contact portions (42) (42) of the slide member (4) (4a) by spring biasing. The first and second slide members (4) and (4a) can be stretched and fitted to the first and second rail portions (3) and (3a).

  By selecting the type of spring (47) and the spring strength, the tension strength of the sliding contact portion (42) with respect to the rail portions (3) (3a) can be selected.

  14a and 14b show a fourth embodiment, in which the sliding surfaces of the rail portions (3) and (3a) with the sliding members (4) and (4a) have a large friction coefficient such as rubber and urethane resin, and are elastic. The resistance member (48) is mounted in a range corresponding to the reclining effective range of the main body (1).

  By forcibly fitting the slide member (4) (4a) into the rail portion (3) (3a) while elastically deforming the resistance member (48), the slide member (4) is elastically restored by the resistance member (48). ) (4a) can be held in tension.

  Since it is not necessary to elastically deform the slide members (4) and (4a), there is a range in selection of the material and shape of the slide members (4) and (4a).

  15a and 15b show a fifth embodiment, in which the sliding contact surfaces of the slide members (4) and (4a) with the rail portions (3) and (3a) have a large friction coefficient such as rubber, urethane resin, etc. and are elastic. A resistance member (48) is mounted.

  The difference from the first embodiment is that when the reclining angle of the main body (1) is set, the slide members (4) and (4a) are not stretched against the rails (3) and (3a).

  Position the slide member (4) (4a) by dropping the slide member (4) (4a) between the adjacent convex portions (49) (49) in the row of convex portions arranged on the rail portion (3) (3a). That is, since the reclining posture of the main body portion (1) is maintained, there is an effect of preventing the user from having a feeling of clicking and changing from the desired posture when changing the reclining posture of the main body portion (1).

  The above description of the embodiments is for explaining the present invention, and should not be construed as limiting the invention described in the claims or reducing the scope thereof. In addition, the configuration of each part of the present invention is not limited to the above embodiment, and various modifications can be made within the technical scope described in the claims.

For example, the first and second rail portions (3) (3a) and the first and second slide members (4) (4a) are both stretched, but only one of them is fitted. You may make it stretch.
Moreover, a rail part may be provided only in any one of a main-body part (1) or a base part (2), and the other may be equipped with the some slide member which can be slid on this rail part compulsorily.

  Moreover, although the rail part (3) (3a) of an Example is curving in circular arc shape, it is not limited to curving to circular arc. It may be simply curved. Moreover, one rail part can also be made into linear form and the other rail part can also be made into circular arc shape.

  Further, the rail portion of the main body portion (1) may be V-shaped, and the base portion (2) may be provided with two slide members that fit on both sides of the V-shaped rail portion.

  Alternatively, the rail portion of the base portion (2) may be V-shaped, and the main body portion (1) may be provided with two slide members that fit on both sides of the V-shaped rail portion.

  In short, the main body part (1) may be guided by the rail parts (3), (3a) and the slide members (4), (4a) so that the reclining locus of the main body part (1) becomes constant.

  Depending on the bending of the rail portions (3) and (3a), the main body portion (1) can be advanced when the main body portion (1) is reclining. In this case, even if there is an obstacle such as a chair behind the main body (1), the main body (1) can be prevented from colliding with the obstacle when reclining.
