2 member via a corresponding rocking assembly so as to operate the reclining chair system in a rocking mode. The support chassis extends between the left and right side frames for operatively supporting a seat and a backrest of the reclining chair system. The footrest is operatively mounted onto the support chassis and is operable therealong between retracted and extended positions via a corresponding deployment assembly so as to operate the reclining chair system in a deployed mode, the footrest being further configured to be operated into an elevated position whereby the deployment assembly of the footrest cooperates with the rocking assembly of the intermediate member so as to prevent the reclining chair system from being operated in the rocking mode. Also described are a method of operating the reclining chair system, and a kit for assembling the same.
Indeed, mobile chairs, such as rocking chairs, for example, are known in the art. The typical rocking chair or rocker is a chair which allows a user to rock back and forth while remaining seated.
The classical design of two curved bands attached to the bottom legs of the chair is well known, but rocking chairs on the market today can take many different configurations. Some rocking chairs can also use different mechanisms for rocking back and forth, and for stopping the rocking action of the chair when desired.
In some rocking chairs, such a mechanism for stopping the rocking action is located or functional in the seat backing, and may thus be difficult to operate for those users which cannot apply force with their back (e.g. the elderly, the infirm, the very young, etc.). Further disadvantageously, the location of these mechanisms in the seat backing places them away from the location of the rocking motion, which typically occurs in or around the seat base. These mechanisms may thus require relatively complex mechanical connections to transfer the force applied by the user so as to stop the rocking motion. Such complex mechanical connections can be more costly

Some rocking chairs use a lever or other similar device mounted to the side of the rocking chair to stop the rocking motion. As with the back-driven mechanism described above, levers are not suitable for certain users of the rocking chair, such as the elderly, infirm, very young, the short, or amputees, which cannot easily access the user.
Hence, in light of the aforementioned, there is a need for an improved mobile chair which would be able to overcome or at least minimize some of the aforementioned prior art drawbacks.
Summary:
An object of the present invention is to provide a mobile chair which, by virtue of its design and features, satisfies some of the above-mentioned needs and which is thus an improvement over other related conventional mobile chairs.
In accordance with the present invention, the above object is achieved, as will be easily understood from the present description, with a self-locking assembly (and/or mobile chair including the same) such as the one briefly described herein and such as the one exemplified in the accompanying drawings.

Broadly described, and as exemplified in the accompanying figures, the present mobile chair (1) includes a support base (3), a moveable seat assembly (5) displaceable with respect to the support base (3), and a self-locking assembly (7).
The self-locking assembly (7) is operatively connectable between the support base (3) and the moveable seat assembly (5), and is operable between engaged and disengaged configurations. In the engaged configuration, a first component (9) of the self-locking assembly (7) operatively connected and/or connectable to the moveable seat assembly (5) is engaged with a second component (11) of the self-locking assembly (7) operatively connectable to the support base, for immobilizing the moveable seat assembly with respect to the support base (3). In contrast, in the disengaged configuration, the first component (9) is disengaged from the second component (11) for allowing displacement of the moveable seat assembly (5) with respect to the support base (3). The self-locking assembly (7) is configured so that one of said first and second components (9,11), acting as a halting component (13), is biased into the engaged configuration by default, and the self-locking assembly (7) is further configured to be operated into the disengaged configuration upon receiving an overriding force from a user of the mobile chair (1) acting on a seat base (15) of the moveable seat assembly (5).
The self-locking assembly (7) can come in many shapes and/or forms, and can provide different interactions between the moveable seat assembly (5) and the support base (3), for ensuring a proper locking (or blocking, etc.) of the moveable seat assembly (5) with respect to the support base (3), when a user of the mobile chair (1) is not sitting thereon, for example.
The first and second components (9,11) of the self-locking assembly (7) could be male and female components respectively, for example, the first component

The self-locking assembly (7) is operatively connectable between the support base (3) and the moveable seat assembly (5), and is operable between engaged and disengaged configurations. In the engaged configuration, a first component (9) of the self-locking assembly (7) operatively connected and/or connectable to the moveable seat assembly (5) is engaged with a second component (11) of the self-locking assembly (7) operatively connectable to the support base, for immobilizing the moveable seat assembly with respect to the support base (3). In contrast, in the disengaged configuration, the first component (9) is disengaged from the second component (11) for allowing displacement of the moveable seat assembly (5) with respect to the support base (3). The self-locking assembly (7) is configured so that one of said first and second components (9,11), acting as a halting component (13), is biased into the engaged configuration by default, and the self-locking assembly (7) is further configured to be operated into the disengaged configuration upon receiving an overriding force from a user of the mobile chair (1) acting on a seat base (15) of the moveable seat assembly (5).
The self-locking assembly (7) can come in many shapes and/or forms, and can provide different interactions between the moveable seat assembly (5) and the support base (3), for ensuring a proper locking (or blocking, etc.) of the moveable seat assembly (5) with respect to the support base (3), when a user of the mobile chair (1) is not sitting thereon, for example.
The first and second components (9,11) of the self-locking assembly (7) could be male and female components respectively, for example, the first component
(9) being removably insertable into the second component (11) when the self-locking assembly (7) is operated into the engaged configuration. Alternatively, the second and first components (11,9) of the self-locking assembly (7) could be male and female components respectively, the second component (11) being removably insertable into the first component (9) when the self-locking assembly (7) is operated into the engaged configuration.
Similarly to the above-described, the halting component (13) of the self-locking assembly (7) can come in various shapes and/or forms, and can provide different interactions between the moveable seat assembly (5) and the support base (3), for ensuring a proper locking (or blocking, etc.) of the moveable seat assembly (5) with respect to the support base (3), when a user of the mobile chair (1) is not sitting thereon, for example.
According to one possible embodiment, the halting component (13) of the self-locking assembly (7) can be a braking component for braking a displacement of the moveable seat (5) assembly with respect to the support base (3).
Alternatively, the halting component (13) of the self-locking assembly (7) could be a blocking component for blocking a displacement of the moveable seat assembly (5) with respect to the support base (3).
One way or another, the halting component (13) of the self-locking assembly (7) is preferably positioned, shaped and sized so as to be biased into the engaged configuration, by default, either naturally by gravity, due to a possible and particular design/weight of the self-locking assembly (7) and/or of components thereof, or the halting component (13) of the self-locking assembly (7) could be biased into the engaged configuration forcefully, by means of a biasing assembly (17), for example.
As can be easily understood, the biasing assembly (17) can come in various shapes and forms, and may include various elaborate components and features, such as electro-mechanical components, for example, but in a simplified manner, the biasing assembly (17) can simply comprise one single spring (19), and according to the embodiments shown in the accompanying drawings, the biasing assembly (17) may comprise a pair of springs (19a,19b), the first spring (19a) being located on one side of the mobile chair (1), and the second spring (19b) being located on another 5 side of the mobile chair (1).
Optionally, each spring (19) is disposed between an application plate (21) and a cross support member (23), the application plate (21) being operatively connectable to the seat base (15) of the moveable seat assembly (5) and being positioned,

, In some embodiments, the support base (3) has two legs (55a,55b) disposed opposite from one another. Optionally, each leg (55) may have an arresting member (39) attached to the leg (55). The arresting member (39) can have a plurality of slots (37) for receiving a component of the self-locking assembly (7) therein, thereby 5 preventing movement of the seat assembly (5). Further optionally, the arresting member (39), or some part thereof, can be inclined relative to the horizontal so as to accommodate the desired seating position of different users. Further optionally, the support base (3) can be a pivoting base so as to allow the user to pivot about the ground surface.
In some embodiments, the mobile chair (1) has two armrests (49a,49b) disposed opposite from one another. The armrests (49) can include motion arms (51) which are rotatably mounted to the legs (55) of the support base (3), thereby allowing the motion arms (51) (and the armrests (49)) to move the seat assembly (5) about the support base (3).
In some embodiments, the seat assembly (5) can be fixedly mounted to the armrests (49). The seat assembly (5) can include a seat base (15) and a seat backing (45), each of which can be structurally reinforced with transversal supports (43,47).
Further optionally, the seat base (15) and/or seat backing (45) can be upholstered, decorated, or otherwise made more comfortable or appealing to the user.
According to another aspect, there is provided a method for allowing and preventing movement of a mobile chair (1) having a support base (3) and a seat assembly (5) moveable about the support base (3), the method comprising the steps of: a) moving the seat assembly (5) about the support base (3) upon a user sitting on the seat assembly (5); and b) preventing movement of the seat assembly (5) about the support base (3) upon the user raising herself/himself from the seat assembly (5) (and more particularly, from the seat base (15) thereof).

, In some embodiments, step a) includes applying a downward force to the seat assembly (5). Step a) can also include decoupling the seat assembly (5) from the support base (3), thereby allowing movement of the seat assembly (5) about the support base (3). In some other embodiments, step b) includes coupling the seat assembly (5) to the support base (3), thereby preventing movement of the seat assembly (5) about the support base (3). In some embodiments, the movement of the seat assembly (5) about the support base (3) is a rocking motion.
An example of a mobile chair (1) (or simply "chair 1") according to a possible embodiment of the present invention is provided in Figure 1. The term "mobile"
refers to the ability of the chair (1) to move, or be moved, with respect to itself, or with respect to the ground surface upon which it rests. For example, the chair (1) can be move in a rocking motion, whereby it pivots back and forth along an arc line.
In another example, the chair (1) can be stationary with respect to the ground surface, but capable of being displaced parallel thereto in frontward, rearward and/or lateral directions. In still yet another example, the chair (1) can be moved with respect to the ground surface. It can thus be appreciated that the mobility of the chair (1) is not limited to a particular direction, orientation, or relative plane. However, for the sole purpose of facilitating the description of the chair (1) and its components and features, the chair (1) will be described herein as a "rocking" chair (1), this description being understood as not limiting the scope of the present disclosure to rocking chairs.
The chair (1) has a support base (3), an example of which is provided in Figure 1. The support base (3) provides stationary, or mobile, support to the chair (1) and the user sitting therein. As such, the support base (3) can take many different forms and configurations. In one possible embodiment, the support base (3) can pivot and/or rock with respect to the ground surface, thereby advantageously allowing the user to rotate or pivot with respect to the ground surface. In other embodiments, such as those shown in the figures, the support base (3) is stationary.
In some embodiments, the support base (3) may have legs (55) which contact the ground and provide the support required of the chair (1). Although shown as having an inversed-"U" configuration, it will be appreciated that the legs (55) can have a different shape, if required and/or desired.
Optionally, each leg (55) can have one or more arresting members (39) attached thereto. Each arresting member (39) assists in stopping or arresting the movement of the seat assembly (5) about the support base (3), as further described below, and also stabilizes the position of the seat assembly (5). The position of the arresting member (39) on each leg (55) can vary as required/desired, and according to the following non-exhaustive list of factors: the nature and/or orientation of the seat assembly (5), the desired stationary positions of the seat assembly (5), the configuration of the self-locking assembly (7), etc.
Figure 2 provides an example of a possible arresting member (39). The arresting member (39) can have a plurality of teeth (41) projecting from a base, and defining slots (37) into which the self-locking assembly (7), or component(s) thereof, can be received. The number of teeth (41), and thus the number of slots (37), can vary as required/required. The arresting member (39) and/or its base can be inclined relative to the horizontal. The angle of inclination can vary depending on numerous factors. The inclination of the arresting member (39) allows the chair (1) to be secured in many different positions, thus allowing many differently sized users to use the chair (1). For example, taller users or users with longer legs may make use of the rear, non-inclined portion of the base and the slots (37) located there. Similarly, shorter users or users with shorter legs may make use of the front, inclined portion of the base and the slots (37) located there.
As mentioned earlier, the chair (1) can have a seat assembly (5), an example of which is shown in Figure 1. The seat assembly (5) allows the user of the chair (1) to be seated, and helps to support the user's weight. As will be further explained below, the seat assembly (5) is moveable about the support base (3). The term "moveable" as used to explain the relationship of the seat assembly (5) with the support base (3) refers to the ability of the seat assembly (5) to be displaced with respect to the support base (3). In most embodiments, but not necessarily all, this displacement is a rocking or pivoting motion. In most embodiments, the displacement of the seat assembly (5) is caused by the user. For example, the user may impart a rocking motion to the seat assembly (5) through her/his legs or arms, or by using some other device mounted to the chair (1). It can thus be appreciated that the seat assembly (5) can take many different forms and configurations in order to achieve such functionality.
One of these possible configurations is shown in Figures 1-4. The seat assembly (5) can include two armrests (49), mounted on opposite sides of the seat assembly (5), so as to support the weight of the user's arms, and so as to help impart motion to the seat assembly (5). The armrests (49) can take any suitable form or configuration, such as the inversed-"U" shape shown in Figure 1. The armrests (49) can each be made of a hollow metallic tube, and may have a diameter of about 1.25", although other materials and dimensions are within the scope of the present disclosure.
The armrests (49) may impart motion to the seat assembly (5) through motion arms (51). Each pair of motion arms (51a,51b) form a link between the seat assembly (5) (via the armrests (49), for example) and the support base (3), thereby allowing for relative motion between both. There can be two motion arms (51) on each side of the seat assembly (5), and each motion arm (51) can have opposed ends. One end of each motion arm (51) can be pivotally mounted to a corresponding armrest (49) so as to allow for relative motion (e.g. rotation) between the motion arm (51) and the armrest (49). The other end of the same motion arm (51) can be pivotally mounted to a corresponding leg (55) of the support base (3) so as to allow for relative motion (e.g. rotation) between the motion arm (51) and the leg (55). Each pair of motion arms (51) can be linked together by a reinforcement rod (53), if required.
This optional configuration of motion arms (51), armrests (49), and legs (55) allows the seat assembly (5) to rock back and forth about the support base (3) in the following possible manner. As the user pushes forward or backward on the armrests (49) with her/his arms or legs, the armrests (49) will be able to rock forward or backward about the point at which the motion arms (51) are pivotally mounted to the legs (55) of the arm. This causes the seat base (15) of the seat assembly (5), which is attached to the armrests (49), to pivot as well, thereby advantageously allowing the chair (1) to rock back and forth.
As previously mentioned, the seat assembly (5) can have a seat base (15), an example of which is also provided in Figures 1-4. The seat base (15) receives the user and provides a comfortable space for her/his to remain seated. The seat base
The step of acting on the seat base (15) can simply consist in sitting on said seat base (15) by the user of the mobile chair (1), although a user may activate the mobile chair (1) into a disengaged configuration by exerting a corresponding overriding force onto the seat base (5), and more particularly, the application plate (21) thereof, by simply manually pressing with sufficient force onto said application plate (21), without sitting, for example, if required/desired.
As previously explained, the mobile chair (1) is an article which is intended to facilitate the movement of a person seated therein, and to aid the person to arrest or stop the movement of the mobile chair (1) when desired. This improved functionality can allow the person to avail himself of the benefits of mobile chairs, while being able to better control its position and orientation.
According to another possible embodiment, there is provided a mobile chair (1) for a user comprising: a support base (3); a seat assembly (5) for seating the user thereon, the seat assembly (5) being moveable about the support base (3); and a self-locking assembly (7) for preventing and allowing movement of the seat assembly (5) about the support base (3), the self-locking assembly (7) being operatively connectable between the support base (3) and the seat assembly (5), and being operable between a movement configuration wherein the self-locking assembly (7) allows the seat assembly (5) to move about the support base (3) upon the user sitting on the seat assembly (5), and an arrested configuration wherein the self-locking assembly (7) prevents the seat assembly (5) from moving about the support base (3) upon the user raising herself/himself from the seat assembly (5).

, In some embodiments, the support base (3) has two legs (55a,55b) disposed opposite from one another. Optionally, each leg (55) may have an arresting member (39) attached to the leg (55). The arresting member (39) can have a plurality of slots (37) for receiving a component of the self-locking assembly (7) therein, thereby 5 preventing movement of the seat assembly (5). Further optionally, the arresting member (39), or some part thereof, can be inclined relative to the horizontal so as to accommodate the desired seating position of different users. Further optionally, the support base (3) can be a pivoting base so as to allow the user to pivot about the ground surface.
In some embodiments, the mobile chair (1) has two armrests (49a,49b) disposed opposite from one another. The armrests (49) can include motion arms (51) which are rotatably mounted to the legs (55) of the support base (3), thereby allowing the motion arms (51) (and the armrests (49)) to move the seat assembly (5) about the support base (3).
In some embodiments, the seat assembly (5) can be fixedly mounted to the armrests (49). The seat assembly (5) can include a seat base (15) and a seat backing (45), each of which can be structurally reinforced with transversal supports (43,47).
Further optionally, the seat base (15) and/or seat backing (45) can be upholstered, decorated, or otherwise made more comfortable or appealing to the user.
According to another aspect, there is provided a method for allowing and preventing movement of a mobile chair (1) having a support base (3) and a seat assembly (5) moveable about the support base (3), the method comprising the steps of: a) moving the seat assembly (5) about the support base (3) upon a user sitting on the seat assembly (5); and b) preventing movement of the seat assembly (5) about the support base (3) upon the user raising herself/himself from the seat assembly (5) (and more particularly, from the seat base (15) thereof).

, In some embodiments, step a) includes applying a downward force to the seat assembly (5). Step a) can also include decoupling the seat assembly (5) from the support base (3), thereby allowing movement of the seat assembly (5) about the support base (3). In some other embodiments, step b) includes coupling the seat assembly (5) to the support base (3), thereby preventing movement of the seat assembly (5) about the support base (3). In some embodiments, the movement of the seat assembly (5) about the support base (3) is a rocking motion.
An example of a mobile chair (1) (or simply "chair 1") according to a possible embodiment of the present invention is provided in Figure 1. The term "mobile"
refers to the ability of the chair (1) to move, or be moved, with respect to itself, or with respect to the ground surface upon which it rests. For example, the chair (1) can be move in a rocking motion, whereby it pivots back and forth along an arc line.
In another example, the chair (1) can be stationary with respect to the ground surface, but capable of being displaced parallel thereto in frontward, rearward and/or lateral directions. In still yet another example, the chair (1) can be moved with respect to the ground surface. It can thus be appreciated that the mobility of the chair (1) is not limited to a particular direction, orientation, or relative plane. However, for the sole purpose of facilitating the description of the chair (1) and its components and features, the chair (1) will be described herein as a "rocking" chair (1), this description being understood as not limiting the scope of the present disclosure to rocking chairs.
The chair (1) has a support base (3), an example of which is provided in Figure 1. The support base (3) provides stationary, or mobile, support to the chair (1) and the user sitting therein. As such, the support base (3) can take many different forms and configurations. In one possible embodiment, the support base (3) can pivot and/or rock with respect to the ground surface, thereby advantageously allowing the user to rotate or pivot with respect to the ground surface. In other embodiments, such as those shown in the figures, the support base (3) is stationary.
In some embodiments, the support base (3) may have legs (55) which contact the ground and provide the support required of the chair (1). Although shown as having an inversed-"U" configuration, it will be appreciated that the legs (55) can have a different shape, if required and/or desired.
Optionally, each leg (55) can have one or more arresting members (39) attached thereto. Each arresting member (39) assists in stopping or arresting the movement of the seat assembly (5) about the support base (3), as further described below, and also stabilizes the position of the seat assembly (5). The position of the arresting member (39) on each leg (55) can vary as required/desired, and according to the following non-exhaustive list of factors: the nature and/or orientation of the seat assembly (5), the desired stationary positions of the seat assembly (5), the configuration of the self-locking assembly (7), etc.
Figure 2 provides an example of a possible arresting member (39). The arresting member (39) can have a plurality of teeth (41) projecting from a base, and defining slots (37) into which the self-locking assembly (7), or component(s) thereof, can be received. The number of teeth (41), and thus the number of slots (37), can vary as required/required. The arresting member (39) and/or its base can be inclined relative to the horizontal. The angle of inclination can vary depending on numerous factors. The inclination of the arresting member (39) allows the chair (1) to be secured in many different positions, thus allowing many differently sized users to use the chair (1). For example, taller users or users with longer legs may make use of the rear, non-inclined portion of the base and the slots (37) located there. Similarly, shorter users or users with shorter legs may make use of the front, inclined portion of the base and the slots (37) located there.
As mentioned earlier, the chair (1) can have a seat assembly (5), an example of which is shown in Figure 1. The seat assembly (5) allows the user of the chair (1) to be seated, and helps to support the user's weight. As will be further explained below, the seat assembly (5) is moveable about the support base (3). The term "moveable" as used to explain the relationship of the seat assembly (5) with the support base (3) refers to the ability of the seat assembly (5) to be displaced with respect to the support base (3). In most embodiments, but not necessarily all, this displacement is a rocking or pivoting motion. In most embodiments, the displacement of the seat assembly (5) is caused by the user. For example, the user may impart a rocking motion to the seat assembly (5) through her/his legs or arms, or by using some other device mounted to the chair (1). It can thus be appreciated that the seat assembly (5) can take many different forms and configurations in order to achieve such functionality.
One of these possible configurations is shown in Figures 1-4. The seat assembly (5) can include two armrests (49), mounted on opposite sides of the seat assembly (5), so as to support the weight of the user's arms, and so as to help impart motion to the seat assembly (5). The armrests (49) can take any suitable form or configuration, such as the inversed-"U" shape shown in Figure 1. The armrests (49) can each be made of a hollow metallic tube, and may have a diameter of about 1.25", although other materials and dimensions are within the scope of the present disclosure.
The armrests (49) may impart motion to the seat assembly (5) through motion arms (51). Each pair of motion arms (51a,51b) form a link between the seat assembly (5) (via the armrests (49), for example) and the support base (3), thereby allowing for relative motion between both. There can be two motion arms (51) on each side of the seat assembly (5), and each motion arm (51) can have opposed ends. One end of each motion arm (51) can be pivotally mounted to a corresponding armrest (49) so as to allow for relative motion (e.g. rotation) between the motion arm (51) and the armrest (49). The other end of the same motion arm (51) can be pivotally mounted to a corresponding leg (55) of the support base (3) so as to allow for relative motion (e.g. rotation) between the motion arm (51) and the leg (55). Each pair of motion arms (51) can be linked together by a reinforcement rod (53), if required.
This optional configuration of motion arms (51), armrests (49), and legs (55) allows the seat assembly (5) to rock back and forth about the support base (3) in the following possible manner. As the user pushes forward or backward on the armrests (49) with her/his arms or legs, the armrests (49) will be able to rock forward or backward about the point at which the motion arms (51) are pivotally mounted to the legs (55) of the arm. This causes the seat base (15) of the seat assembly (5), which is attached to the armrests (49), to pivot as well, thereby advantageously allowing the chair (1) to rock back and forth.
As previously mentioned, the seat assembly (5) can have a seat base (15), an example of which is also provided in Figures 1-4. The seat base (15) receives the user and provides a comfortable space for her/his to remain seated. The seat base
(15) can be fixedly connected to the armrests (49), thereby advantageously allowing the seat base (15) to move along with the armrests (49). The seat base (15) may have a seat backing (45) which supports the back of the user, while the seat base (15), supports the user's bottom. Either one, or both, of the seat backing (45) and the seat base (15) can be reinforced with transversal supports, and either one or both can be upholstered, decorated, or otherwise made more comfortable or appealing for the user.
The self-locking assembly (7) of the present chair (1) can come in many shapes and/or forms, examples of which are shown in Figures 1-4. The self-locking assembly (7) controls the motion of the seat assembly (5) about the support base (3) depending on the user's position on the chair (1). In so doing, the self-locking assembly (7) is able to allow the movement of the seat assembly (5) about the support base (3), and also prevent it.
' , The self-locking assembly (7) can be operatively connectable to both of the support base (3) and the seat assembly (5). The expression "operatively connectable"
refers to the functional link formed by the self-locking assembly (7) between the support base (3) and the seat assembly (5), which permits the self-locking assembly 5 (7) to control a movement of the seat assembly (5) through its connection with the support base (3), as will be further explained below. The self-locking assembly (7) can be operated between the following two configurations: a movement configuration, and an arrested configuration. In the movement configuration, the self-locking assembly (7) allows the seat assembly (5) to move about the support base (3) when 10 the user sits on the seat assembly (5). This movement can be a rocking motion, for example. The movement configuration thus allows the user to "unlock" the seat assembly (5), and rock back and forth in the chair (1). In the arrested configuration, the self-locking assembly (7) prevents the seat assembly (5) from moving about the support base (3) when the user begins to raise herself/himself, or is raised, off of the 15 seat assembly (5). The arrested configuration thus allows the user to "lock", or secure, the chair (1) in its last rocking position, advantageously securing the chair (1) in place. It can thus be appreciated that the self-locking assembly (7) can take many suitable forms and configurations to achieve such functionality.
20 In one possible embodiment, the self-locking assembly (7) can have an application plate (2)1, a biasing assembly (17), lever/activating rods (35,33), and a blocking rod. The application plate (21) engages, directly or indirectly, the bottom of the user sitting on the seat assembly (5). In some embodiments, the application plate (21) extends across the width of the seat base (15), although it can have other configurations. Further optionally, the application plate (21) can have a curvature so as to better conform to the profile of the bottom of the user, and so as to better transmit the user's weight, among other possible reasons. In use, the application plate (21) receives a pressure generated by the user as she/he sits on the seat base (15), and transmits said pressure to the biasing assembly (17) and lever/activating rods (35,33).
The biasing assembly (17), which can be a spring (19), links the application plate (21) to the seat base (15) (such as at a cross support member (23)). The biasing assembly (17) acts to return the application plate (21) to its default position. In most embodiments, the application plate (21) is in the default position when the user is not seated on the seat base (15). In such a default position, the biasing assembly (17) applies a biasing force against the application plate (21), thereby pushing it away from the seat base (15) or cross support member (23) and placing the self-locking assembly (7) in the arrested configuration. In some embodiments, the biasing assembly (17) is mounted at one of its ends to a first projecting support on the application plate (21), and is mounted at the other end to a second projecting support on the cross support member (23). As the biasing assembly (17) is compressed, projecting support can be placed over the smaller-diameter projecting support.
This optional configuration advantageously allows the biasing assembly (17) to apply its biasing force against the application plate (21).
The lever/activating rods (35,33) link the application plate (21) to the blocking rod. Lever rod (35) can be fixedly connected at one of its ends to the application plate (21), and pivotally connected at its other end to a corresponding end of activating rod (33). The connection of lever rod (35) to activating rod (33) can be provided with some play or leeway, to accommodate irregular motions or eccentricities in the rotational movement of the lever/activating rods (35,33) relative to each other.
Similarly, activating rod (33) can be fixedly connected at its other end to the blocking rod. In addition, activating rod (33) can be pivotally mounted to side bracket of the cross support member (23). This advantageously allows activating rod (33) to rotate relative to this side bracket, while still remaining in place.
The blocking rod can extend the entire width of the seat base (15), and can fit at both its ends between the teeth (41) and within the slots (37) of the arresting member (39). Also at each of its ends, the blocking rod can be fixedly attached to ' , corresponding ends of the activating rod (33) such that movements of the activating rods (33) on both sides of the seat base (15) can be transmitted to the blocking rod.
Having described some of the optional components and features of the support base (3), seat assembly (5), and self-locking assembly (7), an example of their cooperation together will now be described to further facilitate understanding of the invention.
In the movement configuration, which can occur when the user sits on the seat base (15) of the seat assembly (5), a downward pressure is applied to the application plate (21). This downward pressure on the application plate (21) causes it to move downwardly, which subsequently causes lever rod (35) to move downwardly. The movement of lever rod (35) downwardly causes the junction of lever rod (35) and activating rod (33) to also move downwardly, which causes activating rod (33) to rotate about the side bracket. The rotation of one extremity of activating rod (33) downwardly causes the other extremity of activating rod (33) to rotate upwardly. As this other extremity of activating rod (33) rotates upwardly, it also rotates blocking rod out of corresponding slots (37) of the arresting members (39), thereby "unlocking" the motion of the seat assembly (5) about the support base (3), and allowing the user to move the seat assembly (5) in a rocking or other desired motion.
In the arrested configuration, which can occur when a user is not sitting on the seat base (15) of the seat assembly (5) or raises herself/himself from the seat base (15), no pressure is applied to the application plate (21). Therefore, the biasing assembly (7) applies the biasing force against application plate (21), pushing it into its default position of extending away from the cross support member (23). This causes lever rod (35) to be pushed away from the cross support member (23), which subsequently causes activating rod (33) and blocking rod to pivot downward such that the extremities of blocking rod are placed within the slots (37) of the arresting members (39). The placement of the blocking rod within the slots (37) prevents the , seat assembly (5) from moving with respect to the support base (3), thereby arresting the motion of the seat assembly (5).
In light of the preceding, it can be appreciated that the present invention may be an improvement over the prior art in that, by virtue of its design and components, the mobile chair (1) can reduce the effort required to perform a rocking motion, and to fix the chair (1) in place as desired. Such ease of use may be particularly useful for users who do not have the strength to apply a force, either by hand or with their body, against the chair (1). Indeed, it can be appreciated that the present invention allows for the operation of the chair (1) by simply sitting upon it, and raising oneself from it.
Furthermore, the cooperation together of the support base (3), seat assembly (5), and self-locking assembly (7) allow for a relatively smooth and reliable operation of the chair (1). The relative simplicity and durability of the components used may help to ensure long time use and low maintenance requirements.
In addition, the chair (1) can be used by many different types of users, whether they be old or young, tall or short, strong or infirm. This versatility advantageously improves the appeal of the chair (1) and its possible attraction in the marketplace.
In ending, the scope of the claims should not be limited by the possible embodiments set forth in the examples, but should be given the broadest interpretation consistent with the description as a whole.
