Description

Specification

Chair type massage machine

Technical field

TECHNICAL FIELD [0001] The present invention relates to a chair type massage machine including a leg holder for holding a calf and a sole of a user in a sitting posture.

Background art

[0002] In a chair type massaging machine that massages the back, waist, calf, soles, etc. of a user in a sitting posture, various devices have been made to provide a higher massage effect to the user. For example, Japanese Published Patent Publication No. 2004-135928 describes a chair type massage machine in which the length of the leg holder can be adjusted according to the body shape of the user.

[0003] This massage machine has a seat, an armrest, a backrest, a leg holder that holds a sole and a calf, and a leg holder that is slidably held with respect to the seat. A pair of slide members formed to be extendable and retractable, a lock means for fixing the leg holding portion to a desired position, and a pair of slide members, which urge the leg holding portion in a direction approaching the seat portion. When the locking means is released by an operating device located above the front part of the armrest, the leg holder can be returned to the initial position on the seat side by the urging force of the urging means. I am doing so.

[0004] In the case of a conventional massage machine, however, the weight of the leg of the user is not evenly applied to the leg holding part or when the user gets on and off the massage machine. If a large load is momentarily applied to one side of the arm, the slide member may be caught and the leg holder may not be smoothly moved. Also, when the biasing means is formed by a single spring, the action of returning the leg holding portion to the initial position on the seat side by the biasing means can be obtained smoothly by the hooking force of the slide member. There may not be.

[0005] Even if the user on the seat adjusts the position of the leg holder in the sitting posture, the position of the leg holder needs to be adjusted again when the user tilts the back and takes the reclining posture. However, in the case of a conventional massage device, a user in a reclining posture wakes up the body. Thus, it was necessary to readjust the position of the leg holder. This puts stress on the operation surface of the massage machine for the user in the reclining posture. Thus, the conventional chair-type massage machine still has room for improvement in terms of the operational reliability of the leg holder and the ease of adjusting the position of the leg holder.

Disclosure of the invention

[0006] Therefore, the present invention has been made in view of the above problems, and an object of the present invention is to provide a chair type massaging machine that can stably obtain a smooth sliding movement of the leg holding portion relative to the seat portion. Is to provide.

[0007] That is, the chair-type massage machine of the present invention holds the legs so that the distance between the seat part, the leg holding part that holds the sole and the calf, and the leg holding part and the seat part is variable. Including a slide mechanism that slidably holds the portion with respect to the seat portion, and a pair of urging means that are provided on both sides of the slide mechanism and provide an urging force in a direction to bring the leg holding portion closer to the seat portion. It is a feature.

[0008] According to the present invention, since the pair of urging means are arranged on both sides of the slide mechanism, the leg holding portion of the user's left leg sole and calf are held, the right leg sole, An urging force can be provided equally to the portion that holds the calf, and a smooth operation of the leg holding portion without a catching force can be obtained. In addition, each urging means can be downsized compared to the case where a single urging means is used (for example, if the urging means is a coil panel, the coil diameter can be reduced), so the leg holder is slim. Can be.

[0009] The massage machine includes a reclining backrest, armrests provided on both sides of the seat, positioning means for locking the slide mechanism to determine the position of the leg holder relative to the seat, and a seat surface side of the armrest. It is preferable to further include an operation lever for the positioning means, particularly when the operation lever is operated in a direction facing the backrest so that the slide mechanism is unlocked by the positioning means. It is preferable to include a motion transmission means for transmitting the motion to the positioning means. Thereby, the user can prevent the user from being stressed on the operation surface of the massage machine that does not need to raise the reclining posture force body in order to adjust the position of the leg holding portion.

[0010] In addition, the thigh massage air nog and the air bag are inflated on the massage machine. When installing an air pump for contraction, it is preferable to place the operation lever between the airbag and the armrest. In particular, the airbag provides a massage to the user's thigh on the seat. It is preferable to have a massage guide surface to be operated and a lever guide portion through which the operation lever can be passed through the surface opposite to the massage application surface. In this case, the massage can be provided to the thigh, and the operation lever can be prevented from touching the user during the massage and the feeling of relaxation is impaired. Furthermore, it is effective in preventing the displacement of the airbag.

[0011] As a particularly preferred embodiment for stably realizing the smooth sliding movement of the leg holding portion described above, the massage machine includes a base frame coupled to the front end portion of the seat portion, and a leg holding portion. And a movable frame that is movably held by the base frame by the slide mechanism. The slide mechanism holds a single slider disposed substantially at the center in the lateral direction of the movable frame, and the slider is slidable. Therefore, the slider holding member is fixed to the base frame, and the pair of urging means are arranged on both sides of the slider, and one end is connected to the movable frame and the other end is connected to the base frame.

[0012] When the massage machine has a base frame connected to the front end portion of the seat portion and a movable frame that is mounted with a leg holding portion and is movably held by the base frame by a slide mechanism, the movable frame is A positioning member that has a plurality of holes in the longitudinal direction and is disposed substantially parallel to the slide mechanism, and the base frame is selectively locked to any one of the plurality of holes of the positioning member. It is preferable to have locking means for locking the sliding movement of the movable frame. In this case, the positioning of the leg holder can be stably performed by the positioning member and the locking means.

[0013] When the massage machine has a base frame connected to the front end portion of the seat portion and a movable frame mounted with a leg holding portion and movably held by the base frame by a slide mechanism, the base frame is And a pair of guide bars extending substantially in parallel with the slide mechanism, and a movable frame force. When the movable frame is rotated around the axis of the slide mechanism, the guide bar is in contact with the guide bar and restricts the rotation. It is preferable to have a means. In this case, even if the user mistakenly applies a large load to only one side of the leg holding member, the movable frame can be prevented from being greatly inclined due to the contact between the guide bar and the stopper means. The safety of the type massage machine can be improved.

[0014] Further, the massage machine described above preferably includes an elastic body that is disposed on at least one of the slider and the slider holding member and provides frictional resistance to the sliding surface between the two. As a result, it is possible to prevent the leg holding portion from suddenly moving toward the seat portion due to the urging force of the pair of urging means, and the chair-type masser as in the case of the guide bar and the stagger means described above. The safety of the machine can be further improved.

[0015] Further objects and advantages of the present invention will be more clearly understood from the following best mode for carrying out the invention.

BEST MODE FOR CARRYING OUT THE INVENTION

Hereinafter, the chair type massage machine of the present invention will be described in detail based on preferred embodiments. [0018] As shown in FIG. 1 (A) and FIG. 1 (B), a chair-type massage machine 1 of the present embodiment includes a seat part 2, a reclining backrest 3 that can be tilted with respect to the seat part, and a foot. It has a leg holder 4 for holding the back and calf and armrests 5 provided on both sides of the seat. Inside the seat 2 and the backrest 3, massage means for massaging the user's waist and back are arranged. In this specification, the direction of the direction of force toward the seat 2 central force leg holder 4 is the front direction, the direction of the force toward the backrest 3 is the rear direction, and the direction of the force toward the pair of armrests 5 Is the horizontal direction

[0019] The leg holding part 4 has a pair of recesses 7 formed so as to accommodate the calves and soles of the left and right legs of the user, and in the recesses 7 massage means (not shown) such as an airbag. Is placed in place, and massage is performed on the soles and calves of the user placed in the leg holder 4 through the upper opening of the recess 7. Further, as shown by an arrow in FIG. 1A, the leg holding portion 4 is held at the front end portion of the seat portion 2 so as to be rotatable around a horizontal axis in the left-right direction. That is, as shown in FIG. 1 (A), the leg holding part 4 is disposed substantially perpendicular to the upper surface of the seat part 2 (stored state), and as shown in FIG. The leg holding part 4 can be rotated between the upper surface of the part 2 and the state in which the leg holding part 4 is disposed substantially horizontally (use state). The leg holder 4 may be manually rotated by the user, or may be rotated by providing a drive device using a motor or air pressure.

As shown in FIGS. 2 to 4, the leg holder 4 is held by the slide mechanism so as to be slid relative to the seat. That is, the massage machine according to the present embodiment includes the base frame 10 that is rotatably held around the horizontal axis in the left-right direction and the leg holder 4 at the front end of the seat 2 and is mounted on the base frame by a slide mechanism. And a movable frame 20 held movably. The base frame 10 and the movable frame 20 are designed to have an optimal skeletal structure in order to obtain the desired rigidity, which is preferably formed of steel or aluminum alloy pipe material. Has achieved a habit. In the drawing, reference numeral 19 denotes a connecting portion of the base frame 10 that is rotatably connected to the front end portion of the seat portion 2. Reference numeral 28 denotes a tread that holds the sole of the user and is fixed to the movable frame 20. Number 29 is a cover that is detachably attached to the movable frame.

[0021] The slide mechanism includes a slider 21 fixed at a substantially center in the left-right direction of the movable frame 20, The slider holding member 11 is fixed to the base frame 10 and slidably holds the slider 21. The movable frame 20 has a plurality of holes 23 in the longitudinal direction and is provided with a positioning member 22 disposed substantially in parallel with the slider 21. The base frame 10 has a plurality of holes 23 in the positioning member 22. Locking means 40 for selectively locking to any one of them and limiting the movement of the movable frame is provided. Furthermore, as an urging means for providing an urging force in a direction in which the movable frame 10 on which the leg holding part 4 is mounted is brought closer to the seat part, a pair of coil panels 30 are separated on both sides of the slider 21 and the slider mosquito is equally spaced in the lateral direction One end of each is connected to the movable frame 20, and the other end is connected to the base frame 10.

As described above, the movable frame 20 is movably held on the base frame 10 by the slider mechanism including the slider 21 and the slider holding member 11. As shown in FIGS. 5 (A) and 5 (B), the slider 21 slides on the inner surface of the slider holding member 11 and a fixed portion 50 that is fixed to the movable frame 20 using an attachment such as a screw. The head portion 52 is in contact with the neck portion 54 which has a cross-sectional shape of V, which is narrower and wider than the head portion, and connects between the head portion and the fixed portion. On the other hand, the slider holding member 11 fixed to the base frame 10 has a C-shaped cross section, and the gap of the opening 60 is slightly larger than the width of the neck 54 smaller than the width of the head 52. . Therefore, as shown in FIG. 5 (B), the slider 21 can be prevented from falling off through the opening 60 of the slider holding member 11 by fitting the head portion 52 of the slider 21 to the inside of the slider holding member 11. The head portion 52 can be slidably contacted with the slider holding member 11 stably.

In FIG. 5A, reference numeral 56 denotes an elastic body arranged at predetermined intervals in the length direction of the slider 21. By arranging the elastic body 56 in this way, it is possible to prevent the movable frame 10 on which the leg holding portion 4 is mounted from moving suddenly toward the seat portion 2 by the urging force of the pair of urging means 30. In the present embodiment, the elastic body 56 is formed using rubber having a hardness of 50 to 70, and the distance between the centers of the adjacent elastic bodies 56 provided on the slider 21 is set not to be larger than the length of the slider holding member 11. It is. As a result, the elastic body 56 provided on the slider 21 always comes into contact with the inner surface of the slider holding member 11, and a stable contact resistance can be obtained. [0024] The material constituting the elastic body 56 and the surface shape of the portion in contact with the inner surface of the slider holding member 11 are not particularly limited as long as a predetermined frictional resistance can be provided. For example, as shown in FIG. As described above, it is preferable to round the corner portion into an arc shape since it is difficult to catch the slider when the slider is moved. In addition, when the concave and convex portions are provided as shown in FIG. 6B, the concave portion functions as a pool of grease, so that smooth sliding movement of the slider 21 can be stably obtained for a long time, and the elastic body 56 Extends life. In the present embodiment, the elastic body 56 is provided on the slider 21 side. However, in order to obtain a predetermined frictional resistance, the elastic body 56 may be disposed on at least one of the slider holding member 11 and the slider 21.

Next, the lock unit 40 that restricts the movement of the movable frame will be described. As shown in FIGS. 7 (A) and 7 (B), the lock means 40 of this embodiment includes a lock pin 70 that can be inserted into one of the holes 23 of the positioning member 22, and the lock pin 70. 23, a lock pin holding member 72 that can be protruded in the housing 23, and a coil spring 74 that provides a spring biasing force in the protruding direction of the lock pin. As shown in FIG. 8, the lock means 40 is remotely operated via a motion transmission mechanism, which will be described later, by operating an operation lever 80 arranged on the seat surface 2 side of the armrest 5. The motion transmission mechanism is configured such that the lock pin 70 can be removed from the hole 23 by operating the operation lever 80 against the panel biasing force of the coil panel 74. That is, as shown in FIG. 7B, when the operation lever 80 is operated, the inner wire 75 connected to the lock pin 70 is connected to the outer wire 77 locked to one end of the lock pin holding member 72. As a result, the lock pin 70 is removed from the hole 23 of the positioning member 22 against the panel biasing force of the coil panel 74. Thereby, the locked state of the leg holding part 4 is released, and the leg holding part 4 can be set to a desired length.

[0026] FIG. 9 introduces a motion transmission mechanism for tensioning the inner wire 75 by operating the operation lever 80 in a direction (A1 direction) toward the backrest 3. The operating lever 80 has a grip portion 82 at the upper end, and the lower end is held rotatably around the horizontal axis L, and the other end of the inner wire 75 is connected. In this state, when the user on the seat 2 pulls the operation lever 80 forward (direction A1), the inner wire 75 is pulled, and the lock pin 70 is removed from the hole 23 of the positioning member 22 by the mechanism described above. . When the operating lever is released, the operating lever 80 moves in the A2 direction and returns to the home position due to the panel force of spring 84. As a result, the lock pin 70 is inserted into the hole 23 of the positioning member 22, and the locked state of the leg holding portion 4 is obtained.

Alternatively, as shown in FIG. 10 (A), by replacing the operating lever 80 with a flexible string material 86 and pulling the string material 86, the inner wire 75 You may make it pull. In this case, it is preferable from the viewpoint of improving the operability that the string member 86 is provided with a shape that can be easily gripped by the user, for example, a grip member 88 as shown in FIG. In this way, by allowing the control lever 80 to be operated in the direction toward the backrest 3 (direction A1), a user in a reclining posture with the backrest 3 tilted can move the slide mechanism without changing the body position. The leg holder 4 can be adjusted to an appropriate position with respect to the seat 2 by releasing the lock.

[0028] In addition, the chair-type massage machine 1 of the present embodiment includes a thigh massage airbag 6 disposed on the armrest 5 side of the seat 2, and an air pump (not shown) for inflating and shrinking the airbag. ). In this case, the operation lever 80 is disposed between the airbag 6 and the armrest 5. As a result, the operation lever 80 can be prevented from interfering with the body of the user during massage, and the user can receive a massage in a relaxed state. Further, it is particularly preferable to provide a lever guide portion 90 through which the operation lever 80 can be passed through on the side opposite to the massage applying surface of the thigh mass surge airbag 6. For example, as shown in FIG. 11 (A) and FIG. 11 (B), the lever guide portion 90 is stitched to a predetermined position of a cloth cover 92 in which the airbag 6 is accommodated, and the string material 86 as an operation lever is attached. You should be able to communicate. As a result, the pulling direction of the string material can be directed to the backrest 3 side without the operation of the string material 86 being obstructed by the airbag 6. A cylindrical member (not shown) made of a material that does not deform by an external force may be disposed in the lever guide portion 90, and the operation lever 80 may be passed through the cylindrical member. In this case, smooth operability of the operation lever 80 is ensured even when the airbag 6 is inflated. In addition, when the operation lever 80 is formed of a flexible material and the cylindrical member is formed of a material having lubricity, the operability of the operation lever 80 is further enhanced by good slidability between them. be able to.

By the way, as described above, when the movable frame 20 is slidably held with respect to the base frame 10 by using the single slider 21 and the slider holding member 11, If a load is applied to one of the left and right sides, the entire movable frame 20 may rotate around the longitudinal axis (slide axis) of the slider 21 and the leg holder 4 may tilt. Therefore, the base frame 10 has a pair of guide bars 15 extending substantially in parallel with the pair of urging means 30, and the movable frame 20 is when the movable frame rotates around the axis of the slider 21. Further, it has a stagger means for contacting the guide bar 15 and restricting the rotation. In this embodiment, the stagger means is formed by a pair of arms 25, and a guide bar 15 is disposed between the pair of arms 25. The distance between the pair of arms 25 is set to be slightly larger than the diameter of the guide bar 15, and normally the guide bar 15 and the arm 25 do not contact each other!

It should be noted that a preferable positional relationship among the slide mechanism constituted by the guide bar 15, the pair of biasing means 30, the slider 21 and the slider holding member 11 is shown in FIGS. As shown in FIG. B), in the view seen from above, a slide mechanism is positioned approximately in the center of the movable frame 20 in the lateral direction (left-right direction), and a pair of urging means 30 are equidistant on both sides of the slide mechanism. Is disposed, and a pair of guide bars 15 is provided on the outer side in the lateral direction further than the pair of urging means. The positioning member 22 provided separately from the slide mechanism is disposed between the biasing means 30 and the slide mechanism on either the left or right side of the slide mechanism.

[0031] An example of how to use the chair-type massage machine 1 will be introduced below. The user sits on the seat part 2 of the chair type massage machine in the housed state of FIG. 1 (A) and rotates the leg holding part 4 to the state shown in FIG. 1 (B). Next, when the user's foot and calf are set in the pair of recesses 7 of the leg holder 4 and the operation lever 80 is operated, the lock pin 70 is removed from the hole 23 of the positioning member 22 and the leg holder 4 seats. The protruding distance from part 2 can be adjusted. At this time, if the holding state of the leg is cramped, the user holds the leg against the urging force of the urging means 30 as shown by the arrows in FIGS. 3 (A) and 4 (A). By pushing the part 4, the protruding distance of the leg holding part 4 from the seat part 2 can be increased, and when the control lever 80 is released at the appropriate position, the lock pin 70 is adjusted to the optimum position of the positioning member 22. Inserted into hole 23, the position of leg holder 4 is locked.

[0032] On the other hand, when the leg holder 4 is fitted to the sole of the user, if the operation lever 80 is operated to cancel the positioning by the locking means 40, FIG. 3 (B) and FIG. As indicated by the arrow in (B), the urging force of the urging means 30 causes the leg holding portion 4 to move toward the seat 2 side. Moving. At this time, the increase in frictional resistance due to the elastic body 56 described above causes the leg holder 4 to move toward the seat 2 at a slow speed, so that the position of the leg holder 4 can be adjusted safely. .

[0033] Even if the user tilts the backrest 3 and adjusts the position of the leg holder 4 in the reclining position, the user is placed between the armrest 5 and the thigh massage airbag 6 described above. By operating the control lever 80, the user can easily adjust the position of the leg holder 4 while keeping the reclining posture without having to wake up. After setting the chair type massage machine 1 in a state suitable for each user, the massage means placed on the backrest 3 and the seat 2, the thigh massage airbag 6, the sole placed in the leg holder and A massage is given to the user using a calf massage means or the like.

Industrial applicability

[0034] As described above, the chair-type massage machine according to the present invention has a slide mechanism disposed substantially at the center of the leg holding portion and a pair of urging means disposed on both sides thereof. As a result, it is possible to reliably obtain the directional force return operation at the initial (rest) position of the leg holding portion on the slide movement, in particular, the seat side of the leg holding portion.

[0035] In addition, by introducing a configuration including a guide bar and a stagger means, it is possible to improve the safety of the chair-type massage machine by restricting the rotational movement of the leg holding portion. Furthermore, when adopting an airbag with a lever guide part, in addition to providing thigh massage, it prevents the position adjustment operation lever from interfering with the user during the massage operation, It can prevent the user's feeling of relaxation. With these effects, chair-type massage machines are expected to become more popular.
