Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to an adjustable frame automatic positioning structure.

[0002]

[Prior art]

 Conventional general adjustable frames are mainly applied to many places that have both protection, outgoing and incoming functions at the same time, for example, various outlets, entrances, product racks, and patient beds. In other words, in addition to providing protection, it always provides access functions according to the needs of the user. An adjustable frame commonly used as a patient bed would be as shown in FIGS. The frame main body 10 includes a set rod 11 attached to an edge of a bed. A rotating connector 12 is provided along the lateral direction of the frame main body 10. A rotating groove 120 and a stopper 121 are formed on the lower side surface of the rotating connector 12, respectively. Under the frame main body 10, a pivot block 14 protrudes in a horizontal direction. The bottom surface of the pivot block 14 has a tooth surface. Further, a rotating connector 22 corresponding to the rotating connector 12 is set above the inverted U-shaped rotating frame 20. A relative rotation groove 220 and a stopper 221 are also formed on the upper surface of the rotation connector 22. As shown in FIG. 2, the two rotary connectors 12 and the rotary connector 22 are relatively pivotally connected via a pivot plug 13. A gear block 25 with a corresponding pivot 14 protrudes below the rotating frame 20. The gear block 25 meshes with the tooth surface 15 of the pivot block 14. At the same time, the corresponding pivot 14 utilizes a spanner 16 having an eccentric shaft hole 17 and the gear block 25 is connected in series via the pool rod 18 to form an adjustable frame.

When using the above-mentioned conventional adjustable frame, first, the spanner 16 is operated upward to separate the gear block 25 of the rotating frame 20 from the tooth surface 15. Then, the adjustment angle of the rotating frame 20 can be turned. When the rotating frame 20 is turned to a required angle, the spanner 16 is operated downward, and the gear block 25 and the tooth surface 15 are engaged again by utilizing the eccentric pivotal relationship between the pool rod 18 and the spanner 16. Since it is fixed, the purpose of adjusting the angle of the rotating frame 20 is achieved.

[0004]

[Problems to be solved by the invention]

 However, the above-described structure and operation have at least the following disadvantages and inconveniences. 1. Inconvenient operation While adjusting the angle, it is necessary to support the rotating frame 20 with one hand and operate the spanner 16 with another hand. In other words, only two hands can achieve the ideal operation and control effects. Unfortunately, when using tools such as a patient's bed, injured person, or disabled person, the user is always in poor physical condition and inconvenient. You can only apply force with one hand and the edge of the bed. Therefore, it is not possible to operate and control the frame with both hands. Conversely, if you forcibly operate with one hand, the adjustment operation will be broken down in multiple stages, which is not only inconvenient, but also slows down.

[0005] 2. Adjustment of the angle is not reliable. If the user does not operate the spanner 16 when adjusting to an appropriate angle, the rotation frame 20 cannot be positioned. If you don't care, you're off. In particular, since the patient, the injured, and the physically handicapped operate with one hand, the rotating frame 20 is likely to be displaced. Therefore, the positioning of the angle cannot be said to be accurate.

[0006] 3. The angle of rotation is small. Since the rotation connector 12 and the stopper 121 of the rotation connector 22 and the stopper 221 are relatively limited, the angle at which the rotation frame 20 can be adjusted is approximately 90 degrees to the left and right. I cannot be satisfied. Accordingly, an object of the present invention is to provide a frame automatic positioning structure that can be conveniently operated and has an improved frame adjustment angle.

[0007]

[Means for Solving the Problems]

 In order to achieve the above object, the automatic positioning structure for a frame according to claim 1 of the present invention is an automatic positioning structure for an adjustable frame, the automatic positioning structure mainly comprising a frame main body and a rotating body. It is pivoted relatively between the frames. The rotating frame can be rotated by the automatic positioning structure so as to face the frame main body, and the position is determined. A pivot shaft is fastened to the frame main body, and a pivot shaft for pivotally mounting the rotating frame is set in the upper inner part of the pivot cylinder. A tooth tube that penetrates to the inside is attached to the bottom end of the pivot tube. From one end of the rotating frame, there is formed an extension step which is inserted into the pivot shaft downward, and a tooth shaft is set at one end where the extension step passes through the pivot shaft.

[0008] A compression spring is interposed between the tooth shaft and the bottom end of the pivot shaft, and the tooth shaft and the cylinder are relatively meshed with each other, so that the angular positioning is accurate, and the operation and control are performed. It is convenient. The frame automatic positioning structure according to a second aspect of the present invention is provided with a protruding stop edge for catching the top edge of the pivot cylinder at the upper end of the pivot shaft mainly composed of the frame. The pivot tube is set on the pivot shaft by bolts. In the automatic positioning structure for an adjustable frame according to the third aspect of the present invention, a tooth tube is set by a bolt on a pivot tube mainly composed of the frame.

 Hereinafter, embodiments of the present invention will be described with reference to the drawings. As shown in FIG. 3, the automatic positioning structure according to the present embodiment is mainly pivotally provided between the frame main body 50 and the rotating frame 60. The frame body 50 has a set rod 51 which is extended downward and is fastened. The rotating frame 60 can be rotated so as to face the frame main body 50 by an automatic positioning structure, and its position is determined.

As shown in FIG. 4, a hollow pivot cylinder 52 is provided on one side of the frame main body 50 corresponding to the rotating frame 60. A pivot shaft 55 for pivoting the rotation frame 60 is set by a bolt 53 in the upper part inside the pivot tube 52. At the upper end of the pivot shaft 55, a stop edge 56 protruding from the top edge of the pivot tube 52 protrudes. At the bottom end of the pivot tube 52, a tooth tube 57 penetrating to the inside is set with a bolt. A large housing groove 58 is formed on the bottom surface of the tooth tube 57, and a sleeve 59 having an inner diameter smaller than the housing groove 58 is arranged at the bottom end of the tooth tube 57 from below, so that the sleeve 59 is installed through the rotating frame 60. .

An upright extending step 61 is formed downward from one end of the rotating frame 60. The extension step 61 is inserted into the pivot shaft 55. A tooth shaft 64 is set with a bolt 62 at one end of the extending step 61 that passes through the pivot shaft 55. Between the tooth shaft 64 and the bottom end of the pivot shaft 55 there is interposed a compression spring 63 which fits outside the extension step 61. The tooth shaft 64 and the tooth cylinder 57 are relatively meshed with each other. At the other end of the rotating frame 60, a bending tube 65 is formed using a connector 650 so as to extend upward.
