Description

Technical Field

[0001] This application relates to the field of companion beds and chairs, and more particularly to a companion bed and chair. Background Technology

[0002] Companion chairs are foldable devices provided for the families of patients in medical institutions. They are characterized by comfort, convenience, and versatility, and are widely used in hospitals, nursing homes, rehabilitation centers, and public places.

[0003] Most existing companion beds / chairs are three-fold, consisting of a first support plate, a second support plate, and a third support plate. When unfolded, they form a bed structure, with the upper surfaces of the first, second, and third support plates coplanar, and the second support plate located between the first and third support plates. When folded, they form a chair structure, with the first and second support plates vertically arranged to form the backrest, and the third support plate horizontally arranged to form the seat.

[0004] The first support plate is hinged to the second support member, and the third support plate is hinged to the second support plate. Therefore, when the companion chair is unfolded, the hinge points between the second support member (located in the middle) and the first and third support plates will bear significant pressure. With increased use, these hinge points are prone to damage, thus affecting the lifespan of the companion chair. Utility Model Content

[0005] In order to ensure the service life of the companion chair by reducing mechanical damage at the hinges, this application provides a companion bed chair.

[0006] The accompanying bed chair provided in this application adopts the following technical solution: A companion bed chair includes a first support plate, a second support plate, and a third support plate; one end of the second support plate is hinged to the first support plate, and the other end is hinged to the third support plate; a support cylinder is hinged to the bottom surface of the second support plate, and the side of the support cylinder near the third support plate is hinged to the second support plate; a support rod is slidably inserted through the support cylinder, and an insert portion is provided at the upper end of the support rod; a limiting groove is provided on the surface of the second support plate near the support rod, and the limiting groove is used for the insertion portion to be inserted; the support cylinder is provided with a first partition portion, and the support rod is provided with a second partition portion; when the companion bed chair is in an unfolded state, the insert portion is inserted into the limiting groove, and the second partition portion is located above the first partition portion with a gap between them; when the companion bed chair is in a folded state, the second partition portion abuts against the first partition portion.

[0007] By adopting the above technical solution, the companion bed chair has two states: folded as a companion chair and unfolded as a companion bed. When the companion bed chair is folded, the first and second support plates are vertically positioned to form the backrest, and the third support plate is horizontally positioned to form the seat. At this time, the bottom surfaces of the first and second support plates are opposite each other, with the bottom surface of the third support plate facing downwards. Furthermore, the second partition abuts against the first partition. When the companion bed chair is unfolded, the first, second, and third support plates are all horizontal and at the same height. At this time, the second partition is positioned above the first partition, the embedded part is inserted into the limiting groove, and the bottom end of the support rod abuts against the bottom surface. Through the cooperation of the embedded part and the limiting groove, the second support plate is stably positioned, and the support rod provides effective support for the second support plate, reducing damage at the hinges between the second and first support plates and between the second and third support plates, thus extending the service life of the companion bed chair.

[0008] Optionally, a suction cup is provided at the end of the support rod away from the second support plate.

[0009] By adopting the above technical solution, a stable connection is established between the support rod and the ground using suction cups, which allows the support rod to make more stable contact with the ground when it is in the unfolded state, thereby enhancing the overall stability of the companion bed chair.

[0010] Optionally, a first magnet is provided on the side of the second support surface near the support cylinder, and a second magnet is provided on the side wall of the support cylinder near the second support plate in the folded state, and the second magnet and the first magnet are magnetically attracted to each other.

[0011] By adopting the above technical solution, when the companion bed and chair are in a folded state, the support cylinder is located between the first support plate and the second support plate. The attraction between the first magnet and the second magnet is used to establish a connection between the side wall of the support cylinder and the bottom surface of the second support plate, which reduces the shaking of the support cylinder during the movement of the companion bed and chair, and also reduces the damage to the hinge between the support cylinder and the companion bed and chair.

[0012] Optionally, the support rod has a mass reduction cavity inside.

[0013] By adopting the above technical solution, the weight of the support rod is reduced, further reducing damage at the hinge between the support cylinder and the accompanying bed chair.

[0014] Optionally, the weight reduction cavity extends along the length of the support rod.

[0015] Optionally, the weight reduction chamber is provided with multiple arc-shaped reinforcing rods, which are arranged along the length of the weight reduction chamber.

[0016] By adopting the above technical solution, based on the fact that the support rod is equipped with a mass reduction cavity, the structural strength of the support rod is increased by using an arc-shaped reinforcing rod, so as to ensure the support rod's ability to support the second support plate.

[0017] Optionally, the support rod is circumferentially connected with a plurality of balls, the outer wall of which is used to abut against the inner wall of the support cylinder.

[0018] By adopting the above technical solution, it is easier for the support rod to slide relative to the support cylinder, and the noise and wear of both during the sliding process are reduced.

[0019] In summary, this application includes at least one of the following beneficial technical effects: 1. The support rod effectively supports the second support plate, reducing damage at the hinge points between the second and first support plates and between the second and third support plates, thus extending the service life of the accompanying bed chair. The engagement of the embedded part and the limiting groove ensures stable positioning of the second support plate. 2. By setting a mass reduction cavity in the support rod and setting an arc-shaped reinforcing rod in the mass reduction cavity, the structural strength of the support rod is ensured while reducing its mass; 3. By using rolling ball bearings to connect the support rod, the smoothness of the sliding of the support rod relative to the support cylinder is improved, reducing noise and wear.

[0024] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0025] This application discloses a companion bed chair.

[0026] Reference Figures 1 to 3A companion bed chair includes a first support plate 1, a second support plate 2, and a third support plate 3. One end of the second support plate 2 is hinged to the first support plate 1, and the other end is hinged to the third support plate 3.

[0027] A support cylinder 4 is hinged to the bottom surface of the second support plate 2, and the side of the support cylinder 4 closest to the third support plate 3 is hinged to the second support plate 2. A support rod 5 slides through the support cylinder 4, and an insert 51 is provided at the upper end of the support rod 5. A limiting groove 21 is provided on the surface of the second support plate 2 near the support rod 5, and the limiting groove 21 is used for inserting the insert 51. The support cylinder 4 is provided with a first partition 41, and the support rod 5 is provided with a second partition 55.

[0028] The support cylinder 4 is provided with a first partition 41, and the support rod 5 is provided with a second partition 55. When the accompanying bed chair is in the unfolded state, the insert 51 is inserted into the limiting groove 21, and the second partition 55 is located above the first partition 41 with a gap between them. When the accompanying bed chair is in the folded state, the second partition 55 abuts against the first partition 41. When the accompanying bed chair is in the unfolded state, the insert 51 is inserted into the limiting groove 21, and the second partition 55 is located above the first partition 41 with a gap between them. When the accompanying bed chair is in the folded state, the second partition 55 abuts against the first partition 41.

[0029] The companion bed / chair has two states: folded, it functions as a companion chair; unfolded, it functions as a companion bed. When unfolded, the first support plate 1, the second support plate 2, and the third support plate 3 are all horizontal and at the same height. At this time, the second partition 55 is positioned above the first partition 41, the insert 51 is inserted into the limiting groove 21, and the bottom end of the support rod 5 abuts against the ground. Through the cooperation of the insert 51 and the limiting groove 21, the second support plate 2 is stably positioned. Simultaneously, the support rod 5 provides effective support for the second support plate 2, reducing damage at the hinge points between the second support plate 2 and the first support plate 1, and between the second support plate 2 and the third support plate 3, thus extending the service life of the companion bed / chair.

[0030] When the companion chair is in the folded state, the first support plate 1 and the second support plate 2 are vertically arranged to form the back of the companion chair, and the third support plate 3 is horizontally arranged to form the seat of the companion chair. At this time, the bottom surface of the first support plate 1 and the bottom surface of the second support plate 2 are opposite to each other, the bottom surface of the third support plate 3 is facing down, the support cylinder 4 and the support rod 5 are located between the first support plate 1 and the second support plate 2, the second partition 55 abuts against the first partition 41, and the support rod 5 is in a suspended state.

[0031] Specifically, the hinge joint between the second support plate 2 and the first support plate 1 has a pull ring 22. To change the folding position of the bed-chair from the unfolded state, simply pull the pull ring 22 upwards. The pull ring 22 can be made of flexible webbing or a rigid material.

[0032] The bottom surface of the third support plate 3 is fixedly connected to a bracket 31, and the end of the bracket 31 that is in contact with the ground is connected to a roller and a brake pad for stopping the brake roller.

[0033] Furthermore, a suction cup 52 is provided at the end of the support rod 5 away from the second support plate 2, so as to establish a stable connection between the support rod 5 and the ground, which can make the support rod 5 more stably contact the ground when it is unfolded, thereby enhancing the overall stability of the companion bed chair.

[0034] Furthermore, a first magnet is provided on the side of the second support surface near the support cylinder 4, and a second magnet is provided on the side wall of the support cylinder 4 near the second support plate 2 in the folded state. The second magnet and the first magnet are magnetically attracted to each other. When the companion bed chair is in the folded state, the support cylinder 4 is located between the first support plate 1 and the second support plate 2. The attraction between the first magnet and the second magnet establishes a connection between the side wall of the support cylinder 4 and the bottom surface of the second support plate 2, reducing the shaking of the support cylinder 4 during the movement of the companion bed chair and also reducing damage to the hinge joint between the support cylinder 4 and the companion bed chair.

[0035] Furthermore, a weight-reducing cavity 53 is provided inside the support rod 5, extending along the length of the support rod 5. This reduces the mass of the support rod 5, further minimizing damage at the hinge between the support cylinder 4 and the accompanying bed chair.

[0036] Multiple arc-shaped reinforcing rods 54 are provided in the weight reduction cavity 53, and the multiple reinforcing rods 54 are arranged along the length direction of the weight reduction cavity 53. Based on the weight reduction cavity 53, the arc-shaped reinforcing rods 54 are used to increase the structural strength of the support rod 5, ensuring the support rod 5's ability to support the second support plate 2.

[0037] In other embodiments, the support rod 5 may also be annular or spherical in shape.

[0038] The implementation principle of a companion bed chair in one embodiment is as follows: When the companion bed chair is in the unfolded state, the first support plate 1, the second support plate 2, and the third support plate 3 are all horizontal and at the same height. At this time, the second partition part 55 is located above the first partition part 41, the embedded part 51 is inserted into the limiting groove 21, and the bottom end of the support rod 5 abuts against the ground through the suction cup 52. Through the cooperation of the embedded part 51 and the limiting groove 21, the second support plate 2 is stably positioned, and at the same time, the support rod 5 provides effective support for the second support plate 2, reducing damage at the hinge points between the second support plate 2 and the first support plate 1, and between the second support plate 2 and the third support plate 3, thus extending the service life of the companion bed chair.

[0039] When the accompanying bed chair needs to be folded, pull the ring 22 between the first support plate 1 and the second support plate 2 upwards, causing the first support plate 1 and the second support plate 2 to gradually change from a horizontal state to a vertical state. During this process, the embedded part 51 gradually disengages from the limiting groove 21, the support rod 5 gradually leaves the ground, and the support rod 5 slides relative to the support cylinder 4 under its own weight. Finally, the first partition part 41 abuts against the second partition part 55. After being folded, the first support plate 1 and the second support plate 2 are vertically arranged to form the backrest of the companion chair, and the third support plate 3 is horizontally arranged to form the seat of the companion chair. At this time, the bottom surface of the first support plate 1 and the bottom surface of the second support plate 2 are opposite to each other, the bottom surface of the third support plate 3 is facing down, the support cylinder 4 and the support rod 5 are located between the first support plate 1 and the second support plate 2, the second partition 55 abuts against the first partition 41, and the support rod 5 is in a suspended state.

[0040] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
