`Description
`
`The present invention relates to a balancing, positioning and fixating assembly for
`
`balancing a treatment device.
`
`Assemblies for balancing, positioning and fixating different treatment devices are
`
`known. However, the known assemblies require many adjustments when one
`
`treatment device is replaced with another. Hence, the operator of the assembly
`
`and the treatment device often uses a lot of strength in holding and adjusting the
`
`10
`
`assembly as well as when the treatment device is being used. Also, the known
`
`assemblies often do not provide good ergonomic positions for the operator of the
`
`treatment device.
`
`It is an object of the present invention to wholly or partly overcome the above
`
`15
`
`disadvantages and drawbacksof the prior art. More specifically,
`
`it is an object to
`
`provide an improved balancing, positioning and fixating assembly with a high
`
`usability and flexibility, and still providing enhanced ergonomic positions for the
`
`operator during use.
`
`20
`
`The above objects,
`
`together with numerous other objects, advantages and
`
`features, which will become evident from the below description, are accomplished
`
`by a solution in accordance with the present invention by a balancing, positioning
`
`and fixating assembly for balancing a treatment device, comprising
`
`- a balance arm having a first arm end and a second arm end,
`
`25
`
`- a stepper part having a first part end and a second part end,

`
`that different treatment devices 2 having different weights may be mounted and
`
`20
`
`used with the assembly 1 and still being hold and maintained in the right position.
`
`Thus, by arranging the spring device 15 in different angles it
`
`is possible in an
`
`expedient manner to balance different weights of the treatment device 2. Hereby
`
`a higher degreeof flexibility is obtained compared to prior solutions.

`
`The slide part 18 is in present embodiment a rod and is securely fasten to a
`
`movement member 22. In other not shown embodiments the slide part 18 may be
`
`movable in the movement member 22.
`
`The movement member 22 is in the present embodiment arranged on a back 23
`
`of a backrest 24 of the chair 3 so that the stepper part and balance arm may be
`
`positioned in relation to a person sitting in the chair 3. Furthermore, the backrest
`
`24 may be moved into different angle positions as indicated with arrow 26 whereby
`
`the balancing, positioning and fixating assembly 1
`
`facilitates positioning and
`
`10
`
`balancing of the treatment device 2 in view of inclination of the backrest, height of
`
`the person, and weight of the treatment device without jeopardizing ergonamic
`
`correct working positions for the operator both during initial adjustments of the
`

`
`that the treatment device 2 may be balanced and positioned at the intended
`
`positions in relation to for instance a person to be treated. By the present assembly
`
`25
`
`1, the operator has a flexible assembly 1 with many adjustment possibilities in
`
`relation to treatment target and the height of the person to treated as well as the
`
`height of the operator. In addition, the operator will be able to have an ergonomic
`
`correct working position without stressing the body by varying the positions of the
`
`treatment device 2.
`
`30
`
`Furthermore, a counterweight 25 is connected with the first slide end 19. The
`
`weight of the counterweight 25 is larger than 5 kg, preferably larger than 8 kg.
`
`The counterweight 25 is securely fastened to the slide part at least in a sideway
`
`35
`
`direction but may also be movable forth and back in a direction being perpendicular
`
`to the sideway direction. The counterweight 25 is configured to balance the stepper
`
`part 7, the balance arm 4 and the treatment device 2 when they are being moved

`

`WO 2022/128991
`
`PCT/EP2021/085608
`
`either to an initial position or during movement of the treatment device 2 in
`
`different angles and/or directions. The counterweight 25 ensures that a state of
`
`equilibrium is instantly obtained without any larger movement between mutual
`
`components of the assembly 1 and/or their inertia.

`In Fig. 3 the balance arm 4 and the stepper part 7 are shown with the covers
`
`removed. The spring device 15 has a first spring end 29 and a second spring end
`
`20
`
`30, the second spring end 30 is fixedly connected to the balance arm 4 closer to
`
`the second arm end 6 than the first arm end 5, and the first spring end 29 is
`
`connected with the first arm end 5 via a variable connection 31 so that the spring
`
`device 15 can be arranged in different angles compared to the longitudinal axis 11
`
`of the balance arm 4. Even though the second spring end 30 is fixedly connected
`
`25
`
`it may pivot around a third pivot joint 32 facilitating that the spring device 15 may
`
`be angled to the intended angle.
`
`In the present embodiment
`
`the spring device 15 is a gas spring.
`
`In other
`
`embodiments the spring device may comprise a spring coil, a hydraulic cylinder,
`
`30
`
`or similar spring-loaded elements, or any combinations thereof.
`
`The predetermined spring force is at least 150 N, and in an embodiment the spring
`
`force is 200 N. The predetermined spring force is chosen in relation to the different
`
`weights of the treatment device, hence the heavier treatment device 2 the higher
`
`35
`
`predetermined spring force, however, the flexibility in different weights of the
`
`treatment device 2 is also obtained by the variable connection 31 as will be further
`
`described below.

`
`10
`
`The variable connection 31 may be stepless or it may have a plurality of
`
`predetermined positions as shown in Fig. 3 and 4.
`
`As mentioned above, each predetermined position of the variable connection 31
`
`corresponds to a weight of the treatment device 2 so that the treatment device is
`
`balanced to a degree wherein it exerts a slight pressure to a head of a patient.
`
`The angles may be between 3 degrees and 20 degrees. However, other angles may
`

`
`In Fig. 6 the movement member 22 is assembled. In the upper housing element
`
`45 a first adjustment opening 48 is arranged. The first adjustment opening 48 is
`
`arranged opposite a corresponding second adjustment opening 49 arranged in the
`
`lower housing element 46. The lower adjustment opening 49 may be arranged with
`
`an internal thread so that and operating bolt 50 (seen in Fig. 7) may be inserted
`
`through first adjustment opening 48 and into second adjustment opening 49. The
`
`bolt having a tread being configured to go into engagement with the internal
`
`thread. In connection with the bolt 50, a handle 51 is arranged. By moving the
`
`10
`
`handle 50 to either side in Fig. 7, the upper housing element 45 and lower housing
`
`element may either be pushed together wherein the ball seats fixate the ball in a
`
`first position wherein the slide part is securely fastened (cannot be angled), and
`
`being released so that the ball seats allow the ball to be moved in relation to the
`
`ball seats, i.e. a second position wherein the slide part is movable (can be angled
`
`15
`
`in any direction). The movement member 22 is also configured to allow
`
`intermediate positions between the completely locked first position and the
`
`released situation in second position.
`
`In these intermediate positions, a minor
`
`pressure is applied to the ball enabling movementof the slide part using a higher
`
`force than when the handle is its second position.
`
`20
`
`In the present embodiment, the handle 51 is configured to manually controlling
`
`the locking member 22.
`
`In another not shown embodiment,
`
`the locking member may be operatively
`
`25
`
`connected with a control device, the control device being configured to allowing
`
`the slide part to be moved (angled) with activation, and to lock the slide part in
`
`position when the control device is deactivated.
`
`In addition,
`
`restrictions in movement of
`
`the slide part are obtained by a
`
`30
`
`predetermined opening 52 as seen in Fig. 6 in the upper housing element 45, the
`
`slide part is extending through the opening 52 and will be restricted in further
`
`movement by a circumference 53 of the opening 52 in all directions so that when
`
`the slide part abuts the circumference 53 it
`
`is hindered in being moved further.
`
`The slide part is movable in all directions within the opening 52. The geometry of
`
`35
`
`the opening 52 is in the present embodiment defined by two half-circles connected
`
`by straight lines. Hereby is obtained that the slide part can be angled more in the
`
`direction between the two half-circles than in the direction being perpendicular

`As mentioned above,
`
`the treatment device is a coil, and wherein the coil
`
`is
`
`configured to TMS (Transcranial Magnetic Stimulation). The coil may be operatively
`
`connected with a magnetic stimulator.
