This application claims the priority of French patent application number 2013786, filed on Dec. 21, 2020, the entire contents of which are incorporated herein by reference.
The invention relates to a massage device for the body, in particular of the type comprising at least one module whose outer surface can be applied onto the area of the body to be massaged, for example by manual rolling.
It applies more particularly to massage devices having at least two possible configurations of use with different massage properties, so as to allow the user to apply different types of treatment with the same device, in particular on different areas of the body.
A massage device is known from document CN-1 448 200 which comprises two modules mounted in translation relative to one another by means of a mechanism that allows their reversible arrangement between a spaced apart position and a close position, each of the modules having cap whose outer surface is arranged to form a massage surface.
This massage device makes it possible to move the two massage surfaces apart or towards one another, but does not provide two massage configurations by means of a specific respective massage surface.
The invention aims to improve the prior art by proposing in particular a massage device which is designed to be selectively arranged in two massage configurations, each forming a specific massage surface, without requiring additional modules.
For this purpose, the invention proposes a massage device comprising two modules which are mounted in relative translation to one another by means of a mechanism that allows them to be arranged reversibly in at least one first—and respectively one second—massage configuration, in which the modules are brought together—or moved apart from one another—, each of said modules having a rear cap whose outer geometry is arranged so as to, in the first massage configuration, form a first massage surface with the cap of the other module, each of the modules having a front extension whose outer geometry is arranged so as to, in the second massage configuration, form a second massage surface with the extension of the other module, said extensions being designed to interlock with one another when the modules are brought together into the first massage configuration.
Additional features and advantages of the invention are given in the following description, which is made with reference to the accompanying figures in which:
A massage device for the body is described below in connection with these figures.
This device can be used in particular to help a sportsperson benefit from muscular recovery after exercise, so as to limit the risk of injury, microtraumas and/or muscle soreness, and thus to be able to resume training and/or the activities of daily life quickly.
Thus, the massage device is particularly suitable for use after a sporting activity which requires intensive muscular effort, such as for example triathlon, running, particularly in a natural environment (trail running, cross-country), cycling, cross-training or weight training exercise.
The massage device has at least two possible configurations of use with different massage properties, so as to enable the user to apply different types of treatment with the same massage device, in particular on different areas of the body.
To this end, the massage device comprises two modules 1 mounted in relative translation to one another by means of a mechanism which allows their reversible arrangement in at least:
Each of the modules 1 has a rear cap 2 whose outer geometry is arranged to form, in the first massage configuration, a first massage surface 3 with the cap 2 of the other module 1, in particular by manually rolling said surface over the area of the body to be massaged.
To achieve this, as shown in
In the embodiment shown, the body 4 has a rear part 4a to which the shell 5 is fixed by means of a screw 6. In particular, the rear part comprises an angular succession of radial blades 7 separated two-by-two by a gap 8, and connected at their rear ends by a platform 9 in which a threaded hole is formed for screwing the shell 5.
The shell 5 has an angular succession of ribs 10 which extend on the inner wall of the shell 5, said ribs cooperating with the blades 7 to prevent any relative rotation of said shell with respect to the body 4, particularly during a massage.
In the embodiment shown, the caps 2 have an hemispherical outer geometry so as to form a first massage surface 3 of a spherical casing.
This first configuration makes it possible to perform a massage which is localized on several areas of the user's body, in particular the back, hips, gluteal muscles, shoulders, feet and hamstring muscles. Furthermore, in this first configuration, the massage device has a reduced size, in particular with a diameter of about 80 mm, which means it can be stored and transported easily, particularly in a sports or travel bag.
With regard to the figures, each shell 5 has a hemispherical geometry, with an outer surface which is covered by a skin 11 of complementary hemispherical geometry, the first massage surface 3 being formed on the outer surface 3a of said skin.
In particular, the skin 11 is fixed onto the shell by overmoulding or by adhesion. In particular, the skin 11 has an annular base 12 provided with ribs 13 that are spaced apart at an angle, so as to form a gripping area to enable the user to easily manipulate the modules 1, in particular to move them between the two massage configurations.
The outer surface of each skin 11 has a structure suitable for massage, in particular with projections 14 having a substantially pyramidal shape distributed evenly over said outer surface. The shape and/or the distribution of the projections 14 can be adjusted according to the type of massage desired.
Thus, the first massage surface 3 is suitable for deep massage, in particular for the prevention and/or relief of pain and/or muscle soreness following a sporting activity.
Each of the modules 1 also has a front extension 15, formed at the front of the body 4 whose outer geometry is arranged to, in the second massage configuration, form a second massage surface 16 with the extension 15 of the other module 1.
Such an arrangement makes it possible to obtain a more complete massage in the second configuration, which is particularly suitable for other parts of the body, such as for example the cervical and spinal muscles.
In particular, the first 3 and second 16 massage surfaces have a different geometry, and the second massage surface 16 is formed between the caps 2 in a spaced apart position, so that said second massage surface is surrounded by two massage surfaces 3a formed by the outer geometry of respectively one of said caps.
Thus, in the second massage configuration, it is possible to simultaneously massage adjacent body parts with massage surfaces 3a, 16 each having a geometry adapted to the shape of respectively the part to be massaged.
In the embodiment shown, the extensions 15 have a truncated conical outer geometry, forming a second massage surface 16 with a rotary conical casing. This geometry is particularly suitable for massaging an area of part of the body with a protruding bone, in particular a clavicle or the vertebral column.
The second surface 16 can have a smoother texture than the first surface 3, which makes it suitable for a more superficial and more comfortable massage, in particular for the purpose of muscle relaxation.
In an advantageous manner, the first 3 and second 16 surfaces can also be made on layers of material, for example foam materials, with different densities and/or hardnesses.
Thus, the first massage surface 3 can have greater rigidity so as to apply deeper pressure on the muscles, and therefore more effectively alleviate the pain and/or muscle soreness caused by a sporting activity.
Conversely, the second massage surface 16 can have greater flexibility, so as to apply a more superficial and comfortable massage to the area concerned, particularly for muscle relaxation purposes.
The extensions 15 are furthermore arranged to be able to interlock with each other when the modules 1 are moved towards the first massage configuration, so as to allow the device to be compact in said first configuration.
For this purpose, the extensions 15 each comprise an angular succession of fingers 17 spaced apart by slots 18 with a complementary form, the fingers 17—respectively the slots 18—of a module 1 being angularly disposed facing the slots 18—respectively the fingers 17—of the other module 1 to allow them to interlock when bringing together the modules 1.
The second massage surface 16 extends over the outer walls of the fingers 17, making it possible to axially superimpose the massage function and the interlocking function of the extensions 15, and thus reduce the bulkiness of the device in the first configuration.
Furthermore, in a first massage configuration, the front ends of the fingers 17 of one extension 15 are arranged to each be disposed in a gap 8 formed between two adjacent radial blades 7 of the body 4 of the other module 1, i.e. the slots 18 are extended backwards by respectively a gap 8.
To enable its displacement between the two massage configurations, the device comprises a shaft 19, on either side of which the modules 1 are mounted in translation.
Furthermore, the extension 15 of each module 1 has a bore 20 opening into the cap 2, each side of the shaft 19 being mounted in translation in a respective bore 20.
In the embodiment shown, each of the bores 20 is provided with a rod 21 which is mounted in translation in the shaft 19, said rods being fixable to the corresponding module 1 by means of the screw 6. In particular, each rod 21 has two diametrically opposed legs 22 which extend axially, said legs each being mounted in a respective translational guide rail 23 formed on the shaft 19.
Advantageously, the legs 22 of a rod 21 are arranged at 90° to the legs 22 of the other rod 21 so as to optimize the amplitude of the relative translation of the modules 1, and thus maximize the area of the massage surfaces.
Each of the modules 1 is provided with at least one means which cooperates geometrically with a complementary means of the shaft 19 to define the relative position of the modules 1 in at least one of the massage configurations.
To this end, each of the rods 21 and the shaft 19 have at least one lug 24—front stop 25 assembly and/or at least one lug 26—rear stop 27 assembly respectively defining a massage configuration.
In particular, as shown in
Furthermore, each leg 22 has a lug 26 formed on the outside of its front end, said lug being intended to abut against a rear edge 27 of the corresponding guide rail 23 during the arrangement of the modules 1 in the second massage configuration.
To avoid any relative displacement of the modules 1 relative to the shaft 19 during the use of the massage device, each of the modules 1 is also provided with at least one means cooperating geometrically with a complementary means of the axis 19 so as to lock the relative position of the modules 1 in at least one of the massage configurations.
To this end, each of the rods 21 and the shaft 19 have at least one projection 28—front housing 31 assembly and/or at least one projection 29—rear housing 30 assembly defining a massage configuration respectively.
In particular, each rod 21 has at least two longitudinal projections 28 angularly spaced apart at an angle in the vicinity of the flange 24, and designed to engage respectively in a front housing 31 formed in the shaft 19 in the vicinity of its corresponding end 25, when said flange comes into frontal abutment against said end so as to lock the modules 1 in the first massage configuration.
Likewise, each lug 26 has at least one lateral projection 29 intended to snap into a housing 30 formed in the rear part of the corresponding guide rail 23, in particular when said lug abuts at the rear against the edge 27 of said rail so as to lock the modules 1 in the second massage configuration.
