Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of operating handle of wheelchair, in particular to a kind of operating handle assembly integrated with brake handle and tilt handle. BACKGROUND

[0002] At present, brake handle and tilt handle of most wheelchairs are separated, for example Figure 1 As shown in the wheelchair, two brake handles 101, 102 are arranged on a horizontal rod, two tilt handles 201, 202 (one for tilting the seat body forward or backward, and the other for adjusting the angle between the seat plate and the backrest) are arranged on two vertical rods, and one brake handle and one tilt handle are arranged on the left and right sides of the person pushing the wheelchair.

[0003] The main disadvantages of completely independent arrangement of brake handle and tilt handle are as follows: first, a relatively large space is occupied, resulting in a less compact structure of the wheelchair; second, the person pushing the wheelchair needs to move a large distance to switch positions between the two handles (one brake handle and one tilt handle) on the corresponding side, which is relatively inconvenient. SUMMARY

[0004] The technical problem to be solved by the utility model is how to arrange brake handle and tilt handle more compactly and conveniently for the person pushing the wheelchair.

[0005] To solve the technical problem, the utility model provides an operating handle assembly. The operating handle assembly comprises a first handle and a second handle, one of the first handle and the second handle is a brake handle, and the other is a tilt handle. The first handle comprises a first fixing seat and a first operating handle, and the second handle comprises a second fixing seat and a second operating handle. The second fixing seat is fixed on the first fixing seat, so that the second handle and the first handle form an integrated operating handle assembly. The operating handle assembly has a connecting structure for fixed connection with a rod.

[0006] The utility model integrates brake handle and tilt handle into one assembly, so that brake handle and tilt handle are arranged more compactly, occupy less space, and are more convenient to operate.

[0007] In some embodiments, the first fixing seat and the second fixing seat are connected in a detachable manner. The coupling interface of the first fixing seat and the second fixing seat is a central symmetric structure. The second fixing seat can be fully coupled with the first fixing seat after rotating 180° relative to the first fixing seat, thereby increasing the flexibility of installation of the operating handle assembly.

[0008] Furthermore, in some embodiments, the second fixed base includes a connecting block and a fixed block, the second operating handle is hinged to the fixed block, the connecting block is detachably fixedly connected to the first fixed base, and the fixed block is detachably fixedly connected to the connecting block. The coupling interface between the fixed block and the connecting block is a centrally symmetrical structure, and the fixed block can still be fully coupled to the connecting block after rotating 180° relative to the connecting block, which further increases the flexibility of the operating handle assembly installation.

[0009] This utility model also provides a wheelchair, including a trolley handle and an operating handle assembly provided by this utility model. The trolley handle includes a rod, and the operating handle assembly is fixed on the rod. The rod is clamped between a first fixed seat and a second fixed seat. The first fixed seat and the second fixed seat together form the connection structure for fixing the rod. The operating handle assembly is fixed by clamping the rod with the first fixed seat and the second fixed seat. No other fixing parts are required, and the structure is simple.

[0017] Figure 2 This is a perspective view of an example wheelchair of this utility model. Figure 2The wheelchair shown has one left and one right trolley handle 1, the function of the trolley handle is to hold the person pushing the wheelchair, as a force medium to push the wheelchair, the operation handle assembly provided by the utility model is basically not limited by the specific structure of the trolley handle, as long as there is space for the operation handle assembly to be installed.

[0018] Referring to Figure 2 and 3 , the trolley handle 1 is mainly composed of a "L" shaped rod 11 and a handle 12 fixed on the rod 11, the operation handle assembly 2 is fixed on the transverse section of the rod 11, and one left and one right operation handle assembly 2 is symmetrically arranged. The operation handle assembly 2 includes a first handle 21 and a second handle 22, the first handle 21 is a brake handle, including a first fixed seat 211 and a first operating handle 212, the first operating handle 212 is hinged to the first fixed seat 211. The second handle 22 is an inclined handle, including a second fixed seat 221 and a second operating handle 222, the second operating handle 222 is hinged to the second fixed seat 221. Two second handles 22 have different functions, one is used to make the wheelchair seat body incline forward or backward, and the other is used to adjust the angle between the seat plate and the backrest.

[0019] In the length direction L of the wheelchair, the free end of the first operating handle 212 is located behind the first fixed seat 211, and the free end of the second operating handle 222 is located behind the second fixed seat 221. In the height direction H of the wheelchair, the second handle 22 is located above the first handle 21. In the width direction W of the wheelchair, the second operating handle 222 is located inside the first fixed seat 211; the pressing direction of the first operating handle 212 is from below to above along the height direction H of the wheelchair, and the pressing direction of the second operating handle 222 is from inside to outside (see Figure 5 ) or from outside to inside (see Figure 2 ) along the width direction W of the wheelchair, which is convenient for the person pushing the wheelchair to press and operate.

[0020] The rod 11 is clamped between the first fixed seat 211 and the second fixed seat 221, two screws S1 are used to lock and connect the first fixed seat 211 and the second fixed seat 221, so that the first fixed seat 211 and the second fixed seat 221 clamp the rod 11, the fixation of the operation handle assembly 2 is realized, and no fixing member outside the operation handle assembly 2 is needed, so the structure is simple. If necessary, those skilled in the art can also design the operation handle assembly to be fixed on the rod 11 through a fixing member outside the operation handle assembly, or redesign the structure of the first fixed seat so that the first fixed seat can be independently fixed on the rod 11, and the second fixed seat is fixed on the first fixed seat.

[0021] To increase the flexibility of installing the operating handle assembly 2, on the basis of detachable connection of the first fixing seat 211 and the second fixing seat 221, the coupling interface of the first fixing seat 211 and the second fixing seat 221 is designed as a central symmetric structure, so that the second fixing seat 221 can be fully coupled with the first fixing seat 211 after rotating 180° relative to the first fixing seat 211 (the rotating direction is shown by the arrow in Figure 6 ).

[0022] The central symmetric structure of the coupling interface of the first fixing seat 211 and the second fixing seat 221 means that the surface M1 of the first fixing seat 211 for coupling (i.e. splicing) with the second fixing seat 221 is a central symmetric structure, and the surface M2 of the second fixing seat 221 for coupling with the first fixing seat 211 is a central symmetric structure.

[0023] The result of the central symmetric structure of the coupling interface of the first fixing seat 211 and the second fixing seat 221 is that the second fixing seat 221 can be fully coupled with the first fixing seat 211 after rotating 180° relative to the first fixing seat 211, i.e. after rotating 180° relative to the first fixing seat 211, the surface M1 and the surface M2 are still fully matched when splicing the first fixing seat 211 and the second fixing seat 221.

[0024] By comparison Figure 2 and Figure 5 , since the second fixing seat 221 can be fully coupled with the first fixing seat 211 after rotating 180° relative to the first fixing seat 211, the two second handles 22 can be exchanged in position, so that the second operating handle 222 is adjusted from being located outside the handle 12 to being located inside the handle 12, preventing the second operating handle 222 from being pressed due to accidental squeezing and bumping.

[0025] Considering that the exchange of the two second handles 22 may cause the wheelchair user to change the established use habit (because the functions of the two second handles 22 are different), to solve the problem of the second operating handle 222 being pressed due to accidental squeezing and bumping, on the basis of the second fixing seat 221 being rotatable 180° relative to the first fixing seat 211, the second fixing seat 221 is designed as a two-piece structure.

[0026] Referring to Figure 4 , the second fixing seat 221 includes a connecting block 2211 and a fixing block 2212, the second operating handle 222 is hinged to the fixing block 2212, the connecting block 2211 is detachably fixedly connected with the first fixing seat 211 by four screws S2, the fixing block 2212 is detachably fixedly connected with the connecting block 2211, and the coupling interface of the fixing block 2212 and the connecting block 2211 is a central symmetric structure, so that the fixing block 2212 can be fully coupled with the connecting block 2211 after rotating 180° relative to the connecting block 2211 (the rotating direction is shown by the arrow in Figure 7The fixed block 2212 can be completely coupled with the connecting block 2211 after rotating 180° relative to the connecting block 2211.

[0027] The center-symmetrical structure of the coupling interface between the fixed block 2212 and the connecting block 2211 means that the face M3 of the fixed block 2212 for coupling with the connecting block 2211 (i.e. for splicing) is a center-symmetrical structure, and the face of the connecting block 2211 for coupling with the fixed block 2212 (i.e. for splicing) is a center-symmetrical structure. Figure 4

[0028] The center-symmetrical structure of the coupling interface between the fixed block 2212 and the connecting block 2211 means that the fixed block 2212 can be completely coupled with the connecting block 2211 after rotating 180° relative to the connecting block 2211, i.e. when splicing the fixed block 2212 and the connecting block 2211, the face M3 and the corresponding face of the connecting block 2211 still completely match after the fixed block 2212 rotates 180° relative to the connecting block 2211.

[0029] Since the second fixed seat 221 can be completely coupled with the first fixed seat 211 after rotating 180° relative to the first fixed seat 211, and the fixed block 2212 can be completely coupled with the connecting block 2211 after rotating 180° relative to the connecting block 2211, the second operating handle 222 can be switched from being located outside the grip handle 12 to being located inside the grip handle 12 without switching the second handle 22 left and right. Taking the left second handle 22 as an example, first rotate the entire second handle 22 180° relative to the first handle 21, and then rotate the fixed block 2212 180° relative to the connecting block 2211.

[0030] Referring to Figure 4 The coupling interface between the fixed block 2212 and the connecting block 2211 is a "C" shaped structure. When splicing the fixed block 2212 and the connecting block 2211, since the connecting block 2211 has a limiting effect on the fixed block 2212 in a direction perpendicular to the splicing direction, it is relatively easy to align the slot on the fixed block 2212 for receiving the screw S2 with the hole on the connecting block 2211 for receiving the screw S2. In contrast, if the coupling interface between the fixed block 2212 and the connecting block 2211 is a plane, when splicing the fixed block 2212 and the connecting block 2211, the connecting block 2211 has no limiting effect on the fixed block 2212 in any direction perpendicular to the splicing direction, and it is relatively difficult to align the slot on the fixed block 2212 for receiving the screw S2 with the hole on the connecting block 2211 for receiving the screw S2.

[0031] Referring to Figure 3 and 4 ​The opposite two faces of the fixed block 2212 are provided with function marks, and the two function marks are respectively used for indicating the function of the second handle 22 before and after the fixed block 2212 rotates 180° relative to the connecting block. The two function marks on the same fixed block 2212 can be designed to be the same or different. The first handle 21 and the second handle 22 are essentially string pulling devices, and the corresponding control function is realized by pulling the steel wire connected thereto. If the second operating handle 222 is found to be inconsistent with the function mark on the fixed block 2212 after being exchanged from the outside of the handle 12 to the inside of the handle 12, the correct steel wire can be connected with the second handle 22.
