Description

Technical Field

[0001] The invention described herein generally relates to a portable chair for supporting a patient during examinations and treatments, and more specifically to a portable chair for dental treatments. Background Technology

[0002] The Ministry of Health regularly provides on-site dental services to public schools and rural areas. Staff traveling to these locations use equipment already available in the clinics, housed in custom-made portable transport kits. For example... Figure 1 As shown, traditional dental chairs used by dental professionals typically consist of a foldable, lightweight seat. The problem with this type of chair is that it is not stable enough and may wobble during dental treatment. Patients may also experience discomfort if the treatment is long because the cushion on a traditional chair is thin.

[0003] Continued use of traditional chairs in the field can also compromise their durability. This is because chairs may be abused by different users and exposed to various environmental conditions during handling. Over time, the structural integrity of the chair may be compromised, making continued use unsafe.

[0004] US4,334,710 shows another example of a traditional chair used for on-site dental treatment that has the same problems mentioned above.

[0021] like Figure 2 and Figure 3As shown, a preferred embodiment of the portable chair 10 for dental treatment includes: a base 20; at least a lifting arm 30, one end of which is pivotally connected to the base 20; a seat assembly 40 having a seat 41, a backrest 42, and a seat assembly support 43; wherein the backrest 42 is pivotally connected to the seat 41; wherein the seat assembly support 43 is pivotally connected to the other end of the lifting arm 30; the base 20 having a compartment 22 substantially large enough to store the seat assembly 40; and the base 20 further including an actuator mechanism 24 pivotally connected to the seat assembly 40 and the base 20.

[0022] The base 20 is made of a robust frame, such as metal, and then constructed into a preferred shape and covered with a material made of fabric, leather, plastic, canvas, etc. The base 20 also has a compartment 22 for storing the seat assembly 40 when folded. A handle 28 is attached to the front of the base 20 using any conventional fastening method, such as screws, rivets, glue, etc. The handle 28 may also be telescopic to accommodate the operator's height during transport of the portable seat 10. When the operator wants to erect the portable seat 10 in the field treatment area, the base 20 is laid flat on a level surface, and the operator can immediately press a button (not shown) on the controller 50. The controller 50 is preferably located on the front, although it can also be located on either side of the base 20. The advantage of placing the controller 50 on the front is that it is easier for the operator to operate the portable seat 10 due to its proximity to the handle 28. Pressing the button activates the actuator mechanism 24 to erect the portable seat 10. The controller 50 may not necessarily be attached to the side of the base. It can also exist in the form of a remote control, which can be connected to the base 20 via a wire or wirelessly. The actuator mechanism 24 is mounted on the base 20, with one end pivotally connected to the seat assembly 40. The operation of the actuator mechanism 24 is controlled by the controller 50, which is powered by an external power source, such as a wall socket, generator, etc. (not shown). Alternatively, it can be powered by an internal power source located within the base 20, such as a battery (not shown). The actuator mechanism 24 is preferably an electric actuator mechanism. However, other types of actuator mechanisms, such as hydraulic or pneumatic, can also be used in this embodiment.

[0023] One end of the lifting arm 30 is pivotally connected to the base 20, and the other end is pivotally connected to the seat assembly support 43. Preferably, the lifting arm 30 comprises two pairs of metal rods covered with a material made of fabric, leather, plastic, canvas, etc. The pivot connection is configured to ensure that the seat assembly 40 can be perfectly inserted into the compartment 22 when folded. Preferably, the lifting arm 30 also has a suitable length and angle when the portable seat 10 is in a reclining position.

[0024] The seat assembly 40 generally consists of a seat 41, a backrest 42, and a seat assembly support 43. Preferably, the seat assembly 40 also includes a headrest 44 and armrests 45.

[0025] The seat 41 may also include a leg support 48 to provide additional comfort for the patient. Preferably, the seat 41 comprises a comfort cushion covered with a waterproof upholstery material (such as leather), a polymer material (PVC, polyurethane, or the like), or any suitable material. The seat 41 is pivotally connected to the backrest 42, which is preferably covered with the same upholstery material as the seat 41. Preferably, the pivotal connection is a hinge 46 so that the backrest 42 can be folded. It may also be adjustable and locked in place. The seat assembly support 43 is pivotally connected to the lifting arm 30 to support the seat assembly 40. The armrest 45 is connected to the seat assembly support 43. Preferably, the connection is a screw, rivet, or any removable fastener. The headrest 44 is located at one end of the backrest 42. It is padded and has a similar upholstery to the seat 41 and backrest 42 to provide additional comfort for the patient.

[0026] Figure 4 A preferred embodiment of the portable seat 10 in its folded position is shown. After the backrest 42 is folded onto the seat 41, the actuator mechanism 24 is activated to retract the seat assembly 40 into the compartment 22. This places the portable seat 10 in the folded position. Preferably, a fastening member 47 is mounted on the backrest 42 to secure it during transport of the portable seat 10. The fastening member 47 may be a flexible strap, hook and loop, button, snapfit, etc. Alternatively, the fastening member may also be mounted on the base 20. This folded position is ideal for transport or storage.

[0027] Preferably, a base support 25 and at least one caster 26 are attached to the rear side of the base 20. The caster 26 is located at the lower part of the rear side to facilitate the movement or transportation of the portable seat 10. The base support 25 is provided at the upper part of the rear side to support the base 20 in an upright position. A protective cover 27 is also installed on the base support 25 to reduce wear. Preferably, the protective cover 27 is made of a rubber-like material or the like.

[0028] Figure 5 A frame assembly of a preferred embodiment of the portable seat 10 is depicted. The base 20 is provided with a base plate 28 for securing the actuator mechanism 24 to the base 20. Figure 5 Also shown is a backrest frame 42' having a headrest plate 44' for securing the headrest 44 to the backrest 42.
