Description

Technical Field

[0001] The invention relates to the field of equipment for the disabled, and in particular to a dining table that assists the disabled with their hands to eat. Background Art

[0002] China has a large population base and a large number of disabled people. It is very difficult for them to eat and drink independently. For them, it is very important to be able to eat and drink by themselves. However, there are some auxiliary feeding devices on the market, but most of them are expensive and complicated to operate, which cannot be accepted by most disabled people. Summary of the invention

[0003] The technical problem to be solved by the present invention is to provide a dining table for assisting hand-disabled persons to eat, so as to facilitate hand-disabled persons to eat by themselves, and the dining table has a simple structure, low cost and easy operation.

[0004] The present invention provides a dining table for assisting hand-disabled persons, comprising: a table body; a first clamp for clamping cups and a second clamp for clamping tableware for eating, wherein the first clamp and the second clamp are respectively located above the table body; a first transmission device, wherein the first transmission device comprises a first pedal for receiving a driving force from a foot, a first transmission mechanism driven by the first pedal, the first clamp being arranged on an output end of the first transmission mechanism, and the first transmission mechanism can convert a driving force parallel to a plane of the first pedal into horizontal movement of the first clamp or rotation around a horizontal axis; a second transmission device, wherein the second transmission device comprises a second pedal for receiving a driving force from a foot, a second transmission mechanism driven by the second pedal, the second clamp being arranged on an output end of the second transmission mechanism, and the second transmission mechanism can convert the driving force into horizontal movement of the second clamp, rotation around a horizontal axis or rotation around a vertical axis.

[0005] Therefore, according to the invented hand-assisted dining table for the disabled, before the disabled eat by themselves, they are first helped to place the cups and eating utensils on the first clamp and the second clamp in advance, and then the disabled can move and tilt the cups by stepping on the first pedal, and move or rotate the fork or spoon by stepping on the second pedal, thereby helping the disabled to drink water and eat. The hand-assisted dining table for the disabled according to the present invention has a simple structure, low cost, and is easy to operate, which improves the subjective initiative of the disabled in self-service eating and can exercise the legs of the disabled.

[0006] On the basis of the above scheme, the present invention can also be improved as follows:

[0007] The first transmission rod mechanism includes a first vertically arranged auxiliary column, a horizontally arranged first connecting rod, a vertically arranged second connecting rod, a horizontally arranged third connecting rod and a first elastic connecting member, the first auxiliary column is fixedly connected to the table body, one end of the first connecting rod is provided with the first pedal, the other end of the first connecting rod is rotatably connected to one end of the second connecting rod, the other end of the second connecting rod is fixedly connected to one end of the third connecting rod, the other end of the third connecting rod is provided with the first clamp, one end of the first elastic connecting member is rotatably connected to the first auxiliary column, and the other end is fixedly connected to the second connecting rod.

[0008] Therefore, the disabled person applies a left or right force to the plane where the first pedal is located through his foot. Under the action of friction, the first pedal drives the first connecting rod, the second connecting rod and the third connecting rod to move left or right, thereby completing the left and right movement of the first clamp (i.e., the cup). At the same time, the first elastic connecting member completes the contraction or extension action. When the first pedal is released, the first elastic connecting member is reset under the action of the restoring force, and the first clamp returns to its initial position.

[0009] The disabled person applies a force forward or to the right in the plane where the first pedal is located. Under the action of friction, the first pedal drives the first connecting rod, the second connecting rod and the third connecting rod to rotate around the axis direction where the first elastic connecting member is located, so that the first clamp (i.e., the cup) is tilted, and the disabled person completes the process of drinking water. Therefore, by controlling the direction of the force applied, the water (fluid food) in the cup can be easily drunk.

[0010] Furthermore, the clamping diameter of the first clamp is adjustable, and the first transmission device also includes a pulley assembly, which converts the driving force perpendicular to the first pedal plane into the adjustment of the clamping diameter of the first clamp.

[0011] According to the auxiliary hand-disabled dining table according to the embodiment of the present invention, the pulley assembly includes a first pulley, a second pulley and a first steel wire rope, the first pulley is fixedly provided at one end of the first connecting rod close to the second connecting rod, the second pulley is provided at one end of the second connecting rod close to the third connecting rod, one end of the first steel wire rope is fixedly connected to the first pulley, and the other end passes around the second pulley and is connected to the first clamp for adjusting the clamping diameter of the first clamp 1.

[0012] Therefore, by adjusting the clamping diameter of the first clamp, the horizontal movement of the first clamp and the tilting operation of the first clamp, the cup can be clamped, moved and tilted, so that the disabled can take and drink water from the cup by themselves.

[0013] Furthermore, the first clamp includes a first clamp and a second clamp hinged to each other and an adjusting member for adjusting the rotation angle of the first clamp and the second clamp around the hinge axis, the adjusting member is fixedly connected to the first steel wire rope, and the hinge axis is fixedly connected to the third connecting rod.

[0014] The disabled person steps on the first pedal to rotate the first connecting rod along its axis, drives the first pulley to rotate, contracts the first steel wire rope on the first pulley, pulls the first clamp to open the first clamp (i.e., the first clamp and the second clamp have larger clamping diameters), and applies force to the left and right along the plane where the first pedal is located, so that the first clamp moves to the left and right to the position where the cup is located. When the cup is located in the clamping opening of the first clamp, the magnitude and direction of the applied force are changed to slowly rotate the first connecting rod in the opposite direction along its axis, adjust the clamping diameter to clamp the cup firmly, and then rotate the third connecting rod around the axis where the first elastic connector is located to achieve the tilting of the first clamp (i.e., the cup), thereby completing the process of clamping the cup and the process of drinking water or liquid food in the cup. In this process, the angle of rotation of the first pedal around the axis of the first connecting rod can be used to control the rotation angle of the first clamp and the second clamp to adapt to clamping cups of different specifications, thereby achieving the clamping of cups of different sizes.

[0015] Specifically, the adjusting member includes a first adjusting rod, a second adjusting rod and a third adjusting rod, one end of the first adjusting rod, one end of the second adjusting rod and one end of the third adjusting rod are hinged by the same pin, the other end of the first adjusting rod is hinged to the first clamp, the other end of the second adjusting rod is hinged to the second clamp, the other end of the third adjusting rod is connected to the first steel wire rope, a first compression spring is sleeved on the outer wall of the third adjusting rod, and a first limit block and a second limit block for compressing and limiting the first compression spring are respectively arranged on the outer wall of the third adjusting rod and the inner wall of the third connecting rod.

[0016] As a result, the first steel wire rope contracts, and the first steel wire rope pulls the third adjusting rod to move, causing the first compression spring to be further compressed, driving the second adjusting rod and the third adjusting rod to move, and at the same time driving the second adjusting rod and the third adjusting rod to approach each other, thereby pulling the first clamp and the second clamp to rotate and open, the first steel wire rope relaxes, the first compression spring resets, and pushes the first clamp and the second clamp to approach each other, thereby clamping the cup.

[0017] According to the auxiliary hand-disabled dining table of the embodiment of the present invention, the second transmission mechanism includes a second transmission rod assembly and a second pulley assembly located on the second transmission rod assembly, and the second pedal is arranged on the second transmission rod assembly, which is used to drive the second transmission rod assembly to drive the second clamp to move in the horizontal plane and rotate around the horizontal axis, and / or drive the second pulley assembly to drive the second clamp to rotate in the vertical plane.

[0018] Further, the second transmission rod assembly includes a vertically arranged second auxiliary column, a horizontally arranged fourth connecting rod, a vertically arranged fifth connecting rod, a horizontally arranged sixth connecting rod and a second elastic connecting piece, the second auxiliary column is fixedly connected to the table body, one end of the fourth connecting rod is provided with the second pedal, the other end of the fourth connecting rod is rotatably connected to one end of the fifth connecting rod, the other end of the fifth connecting rod is fixedly connected to one end of the sixth connecting rod, the other end of the sixth connecting rod is provided with the second clamp, one end of the second elastic connecting piece is rotatably connected to the second auxiliary column, and the other end is fixedly connected to the fifth connecting rod.

[0019] The disabled person applies a left or right force to the plane where the second pedal is located by foot. Under the action of friction, the second pedal drives the fourth connecting rod, the fifth connecting rod and the sixth connecting rod to move left or right, thereby completing the left and right movement of the second clamp, i.e., the tableware for taking food. At the same time, the second elastic connecting member completes the contraction or extension action. When the second pedal is released, the second elastic connecting member is reset under the action of the restoring force, and the second clamp returns to the initial position.

[0020] The disabled person applies a forward or rightward force to the plane where the second pedal is located. Under the action of friction, the second pedal drives the fourth connecting rod, the fifth connecting rod and the sixth connecting rod to rotate around the axis direction where the second elastic connecting member is located, so that the second clamp, i.e. the eating cutlery (spoon or fork), is tilted, thereby completing the process of the disabled person eating real food.

[0021] Preferably, the table body includes a first table leg located at the left front side of the table body, a second table leg located at the left rear side of the table body, a third table leg located at the right front side of the table body and a fourth table leg located at the right rear side of the table leg, a horizontally arranged first cross bar, a horizontally arranged second cross bar and a horizontally arranged third cross bar, two ends of the first cross bar are respectively fixed to the first table leg and the second table leg, two ends of the second cross bar are respectively fixed to the third table leg and the fourth table leg, the first cross bar is provided with a first slide groove along its axial direction, the second cross bar is provided with a second slide groove along its axial direction, the first auxiliary column and the second auxiliary column are respectively located at the left and right sides of the table body, one end of the third cross bar passes through the first slide groove and is fixedly connected to the first auxiliary column, the other end of the third cross bar passes through the second slide groove and is fixedly connected to the second auxiliary column, and a fourth limit block and a fifth limit block are respectively provided on the third cross bar for preventing the third cross bar from sliding left and right.

[0022] Therefore, before eating, the third cross bar can be manually pushed to slide along the first slide groove and the second slide groove, thereby driving the first transmission mechanism, the first pedal, the second transmission mechanism and the second pedal 6 to move forward and backward, thereby achieving a rough adjustment of the forward and backward movement of the first clamp and the second clamp above the table top. The setting of the fourth limit block and the fifth limit block can improve the stability of the device when in use.

[0023] Further, the second pulley assembly includes a third pulley, a fourth pulley, a second steel wire rope and a seventh connecting rod horizontally arranged below the sixth connecting rod, the seventh connecting rod is fixedly connected to the fifth connecting rod, the third pulley is fixedly arranged at one end of the fourth connecting rod close to the fifth connecting rod, the fourth pulley is arranged at the position between the fifth connecting rod and the seventh connecting rod, one end of the second steel wire rope is fixedly connected to the third pulley, and the other end bypasses the fourth pulley and is connected to the second clamp, so as to drive the second clamp to rotate in a vertical plane.

[0024] Furthermore, the second clamp includes an eighth connecting rod located below the sixth connecting rod, a ninth connecting rod located below the sixth connecting rod, and a third chuck for fixing eating utensils, the third chuck is hinged to the sixth connecting rod, one end of the eighth connecting rod is sleeved in the seventh connecting rod and connected to the second steel wire rope, one end of the ninth connecting rod is hinged to the other end of the eighth connecting rod, and the other end is hinged to the bottom of the third chuck.

[0025] Specifically, the tableware for taking food is selected from any one of a fork or a spoon.

[0026] Specifically, a second compression spring is provided on the outer wall of the eighth connecting rod 62, the second compression spring is provided on the inner wall of the seventh connecting rod and the outer wall of the eighth connecting rod 61, respectively, and a third limit block and a fourth limit block for compressing and limiting the second compression spring are provided on the outer wall of the third adjusting rod 143 and the inner wall of the third connecting rod 23, respectively.

[0027] Thus, the disabled person applies force left and right along the plane where the second pedal is located by his feet, so that the second clamp, i.e., the eating cutlery, moves left and right, and moves it above the position where the eating cutlery is located. Then, the fourth connecting rod rotates along its axial direction by stepping on the second pedal, driving the second pulley to rotate, so that the second steel wire rope on the first pulley contracts, and the second steel wire rope pulls the eighth connecting rod, the ninth connecting rod, and the third clamp in turn, so that the third clamp rotates downward in the vertical plane. At the same time, the second compression spring is further compressed, the first steel wire rope is relaxed, the second compression spring is reset, and the third clamp is reset. By controlling the size and direction of the applied force, the first connecting rod can be slowly rotated in the opposite direction along its axis, and the third clamp can be rotated around the second elastic connecting piece, so that the eating cutlery can be taken and fed.

[0028] Specifically, the fork or spoon is connected to the third clamp via bolts, thereby facilitating the disassembly and replacement of eating utensils of different specifications to adapt to the clamping of different foods, thereby improving the practicability of the device.

[0029] Furthermore, the first elastic connecting member includes a cylinder, a rod and a spring, one end of the cylinder is rotatably connected to the first auxiliary column, and the other end is sleeved with the rod, the cylinder is connected to the rod along its axial direction through a slide groove and a slider, the spring is arranged in the cylinder, one end of the rod is fixedly connected to the spring, and the other end is fixedly connected to the second connecting rod.

[0030] Since the cylinder body and the rod body are connected by the slide groove and the slider, when the disabled person applies a force forward or rightward to the plane where the first pedal is located, under the action of friction, the first pedal drives the first connecting rod and the second connecting rod to rotate, and the cylinder body and the rod body rotate around the axis direction where the cylinder body is located, thereby realizing the tilting of the first clamp, i.e., the cup; when the first pedal drives the first connecting rod, the second connecting rod and the third connecting rod to move left or right, the spring is subjected to subcontraction or extension, thereby realizing the action of the first clamp (i.e., the cup) moving left and right, and the first pedal is released, the spring is reset under the action of the restoring force, and the first clamp returns to the initial position.

[0031] Furthermore, by pulling the steel wire rope to pull the cups and eating utensils to the appropriate position, the disabled can eat and drink. The first clamp is opened and the cup is placed in the first clamp by stepping on the first pedal, so as to clamp the cup. The first pulley is rotated to step on the first pedal to control the rotation angle, thereby pulling the first steel wire rope and controlling the opening angle of the first clamp, so as to adapt to cups of different specifications; the first pedal is rotated to rotate around the axis of the first elastic connector, so as to rotate the first fixture and tilt the cup, so as to facilitate the disabled to drink. Similarly, by stepping on the second pedal on the right, the spoon or fork can be rotated up and down around the hinge of the third clamp and the sixth connecting rod in the vertical plane, moved left and right in the horizontal direction, and rotated around the axis of the second elastic connector.

The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0045] Combine the following Figure 1-4 The present invention is described with reference to specific embodiments.

[0046] like Figure 1 As shown, the dining table for assisting hand-disabled persons according to the present invention comprises: a table body 7;

[0047] A first clamp 1 for clamping cups and a second clamp 4 for clamping tableware for eating, the first clamp 1 and the second clamp 4 are respectively located above the table body; a first transmission device, the first transmission device includes a first pedal 3 for receiving a driving force from the foot, a first transmission mechanism 2 driven by the first pedal 3, the first clamp 1 is arranged on the output end of the first transmission mechanism 2, the first transmission mechanism 2 can convert the driving force parallel to the plane of the first pedal 3 into horizontal movement of the first clamp 1 or rotation around a horizontal axis; a second transmission device, the second transmission device includes a second pedal 6 for receiving a driving force from the foot, a second transmission mechanism 5 driven by the second pedal 6, the second clamp 4 is arranged on the output end of the second transmission mechanism 5, the second transmission mechanism 5 can convert the driving force into horizontal movement of the second clamp 4, rotation around a horizontal axis or rotation around a vertical axis.

[0048] Therefore, according to the invented hand-assisted disabled dining table, before the disabled person eats by themselves, they are first helped to place the cups and eating utensils on the first clamp and the second clamp 4 in advance, and then the disabled person steps on the first pedal to move and tilt the cups, and steps on the second pedal to move or rotate the fork or spoon, thereby helping the disabled person to drink water and eat. The hand-assisted disabled dining table according to the present invention has a simple structure, low cost, and convenient operation, improves the subjective initiative of the disabled person in self-service eating, and can exercise the disabled person's legs.

[0049] According to the auxiliary dining table for hand-disabled persons in an embodiment of the present invention, the first transmission rod mechanism includes a vertically arranged first auxiliary column 25, a horizontally arranged first connecting rod 21, a vertically arranged second connecting rod 22, a horizontally arranged third connecting rod 23 and a first elastic connecting member 24. The first auxiliary column 25 is connected and fixed to the table body 7, a first pedal 3 is provided at one end of the first connecting rod 21, the other end of the first connecting rod 21 is rotatably connected to one end of the second connecting rod 22, the other end of the second connecting rod 22 is connected and fixed to one end of the third connecting rod 23, the other end of the third connecting rod 23 is provided with a first clamp 1, one end of the first elastic connecting member 24 is rotatably connected to the first auxiliary column 25, and the other end is fixedly connected to the second connecting rod 22.

[0050] Thus, the disabled person applies a left or right force to the plane where the first pedal 3 is located through his foot. Under the action of friction, the first pedal 3 drives the first connecting rod 21, the second connecting rod 22 and the third connecting rod 23 to move left or right, thereby completing the left and right movement of the first clamp 1 (i.e., the cup). At the same time, the first elastic connecting member 24 completes the contraction or extension action. When the first pedal 3 is released, the first elastic connecting member 24 is reset under the action of the restoring force, and the first clamp 1 returns to its initial position.

[0051] The disabled person applies a force forward or rightward to the plane where the first pedal 3 is located. Under the action of friction, the first pedal 3 drives the first connecting rod 21, the second connecting rod 22 and the third connecting rod 23 to rotate around the axis direction where the first elastic connecting member 24 is located, so that the first clamp 1 (i.e., the cup) is tilted, and the disabled person completes the process of drinking water. Therefore, by controlling the direction of the force applied, the water (fluid food) in the cup can be easily drunk.

[0052] According to the auxiliary dining table for hand-disabled persons according to an embodiment of the present invention, the clamping aperture of the first clamp is adjustable, and the first transmission device further comprises a pulley assembly, which converts the driving force perpendicular to the plane of the first pedal 3 into the adjustment of the clamping aperture of the first clamp 1.

[0053] According to the embodiment of the auxiliary hand-disabled dining table of the present invention, the pulley assembly includes a first pulley 26, a second pulley and a first steel wire rope. The first pulley 26 is fixedly provided at one end of the first connecting rod 21 close to the second connecting rod 22, and the second pulley 26 is provided at one end of the second connecting rod 22 close to the third connecting rod 23. One end of the first steel wire rope is fixedly connected to the first pulley 26, and the other end passes around the second pulley and is connected to the first clamp 1 for adjusting the clamping diameter of the first clamp 1.

[0054] Therefore, by adjusting the clamping diameter of the first clamp 1, the horizontal movement of the first clamp 1 and the tilting operation of the first clamp 1, the cup can be clamped, moved and tilted, so that the disabled can take and drink water from the cup by themselves.

[0055] like Figure 1 and 2 As shown, according to the auxiliary hand-disabled dining table according to an embodiment of the present invention, the first clamp 1 includes a first clamp 11 and a second clamp 12 hinged to each other and an adjusting member 14 for adjusting the rotation angle of the first clamp 11 and the second clamp 12 around a hinge shaft 13, the adjusting member 14 is fixedly connected to the first steel wire rope, and the hinge shaft 13 is fixedly connected to the third connecting rod 23.

[0056] The disabled person steps on the first pedal 3 to rotate the first connecting rod 21 along its axial direction, driving the first pulley 26 to rotate, causing the first steel wire rope on the first pulley 26 to contract, and the first steel wire rope pulls the first clamp 1 to open the first clamp 1 (that is, the clamping diameter of the first clamp 11 and the second clamp 12 becomes larger), and at the same time, a force is applied left and right along the plane where the first pedal is located to move the first clamp 1 left and right to the position where the cup is located. When the cup is located in the clamping opening of the first clamp, the size and direction of the applied force are changed to make the first connecting rod slowly rotate in the opposite direction along its axis, adjust the clamping diameter to clamp the cup firmly, and then rotate the third connecting rod 23 around the axial direction where the first elastic connecting member 24 is located to achieve the tilting of the first clamp 1 (that is, the cup), thereby completing the process of clamping the cup and the process of drinking water or liquid food in the cup. In this process, the first pedal 3 can be rotated around the axis of the first connecting rod 21 to control the rotation angle of the first clamp 11 and the second clamp 12 to adapt to clamping cups of different specifications, thereby achieving the clamping of cups of different sizes.

[0057] Specifically, Figure 2 As shown, the adjusting member 14 includes a first adjusting rod 141, a second adjusting rod 142 and a third adjusting rod 143. One end of the first adjusting rod 141, one end of the second adjusting rod 142 and one end of the third adjusting rod 143 are hinged by the same pin shaft 144. The other end of the first adjusting rod 141 is hinged to the first chuck 11, the other end of the second adjusting rod 142 is hinged to the second chuck 12, and the other end of the third adjusting rod 143 is connected to the first steel wire rope. A first compression spring 145 is sleeved on the outer wall of the third adjusting rod, and a first limit block 146 and a second limit block 147 for compressing and limiting the first compression spring are respectively arranged on the outer wall of the third adjusting rod 143 and the inner wall of the third connecting rod 23.

[0058] As a result, the first steel wire rope contracts, and the first steel wire rope pulls the third adjusting rod 143 to move to the left (at this time, the first compression spring 145 is further compressed), driving the second adjusting rod 142 and the third adjusting rod 143 to move to the left, and at the same time driving the second adjusting rod 142 and the third adjusting rod 143 closer to each other, thereby pulling the first clamp 11 and the second clamp 12 to rotate and open, the first steel wire rope is relaxed, and the first compression spring 145 is reset, pushing the first clamp 11 and the second clamp 12 closer, so that the cup can be clamped.

[0059] According to the auxiliary dining table for hand-disabled persons according to an embodiment of the present invention, the second transmission mechanism 5 includes a second transmission rod assembly and a second pulley assembly located at the second transmission rod assembly, and the second pedal 6 is arranged on the second transmission rod assembly, which is used to drive the second transmission rod assembly to drive the second clamp 4 to move in the horizontal plane and rotate around the horizontal axis, and / or drive the second pulley assembly to drive the second clamp 4 to rotate in the vertical plane.

[0060] According to the auxiliary dining table for hand-disabled persons according to an embodiment of the present invention, the second transmission rod assembly includes a vertically arranged second auxiliary column 55, a horizontally arranged fourth connecting rod 51, a vertically arranged fifth connecting rod 52, a horizontally arranged sixth connecting rod 53 and a second elastic connecting member. The second auxiliary column 55 is fixedly connected to the table body 7, a second pedal 6 is arranged at one end of the fourth connecting rod 51, the other end of the fourth connecting rod 51 is rotatably connected to one end of the fifth connecting rod 52, the other end of the fifth connecting rod 52 is fixedly connected to one end of the sixth connecting rod 53, the other end of the sixth connecting rod 53 is provided with a second clamp 4, one end of the second elastic connecting member is rotatably connected to the second auxiliary column 55, and the other end is fixedly connected to the fifth connecting rod 52.

[0061] The disabled person applies a left or right force to the plane where the second pedal 6 is located by foot. Under the action of friction, the second pedal 6 drives the fourth connecting rod 51, the fifth connecting rod 52 and the sixth connecting rod 53 to move left or right, thereby completing the left and right movement of the second clamp 4, i.e., the tableware for taking food. At the same time, the second elastic connecting member completes the contraction or extension action. When the second pedal 6 is released, the second elastic connecting member is reset under the action of the restoring force, and the second clamp 4 returns to the initial position.

[0062] The disabled person applies a forward or rightward force to the plane where the second pedal 6 is located. Under the action of friction, the second pedal 6 drives the fourth connecting rod 51, the fifth connecting rod 52 and the sixth connecting rod 53 to rotate around the axis direction where the second elastic connecting member is located, so that the second clamp 4, i.e. the eating tableware (spoon or fork), is tilted, thereby completing the process of the disabled person eating real food.

[0063] Preferably, the table body 7 comprises a first table leg 71 located at the left front side of the table body, a second table leg 72 located at the left rear side of the table body, a third table body 73 located at the right front side of the table body, a fourth table body 74 located at the right rear side of the table body, a first horizontal cross bar 75, a second horizontal cross bar 76 and a third horizontal cross bar 77, the two ends of the first cross bar 75 are respectively fixed to the first table leg 71 and the second table leg 72, the two ends of the second cross bar 76 are respectively fixed to the third table leg 73 and the fourth table leg 74, and the first cross bar 75 is arranged along its axial direction. A first slide groove 751 is provided on the top, and a second slide groove 761 is provided along the axial direction of the second cross bar 76. The first auxiliary column 25 and the second auxiliary column 55 are respectively located on the left and right sides of the table body 1. One end of the third cross bar 77 passes through the first slide groove 751 and is fixedly connected to the first auxiliary column 25, and the other end of the third cross bar 77 passes through the second slide groove 761 and is fixedly connected to the second auxiliary column 55. The third cross bar 77 is respectively provided with a fourth limit block 771 and a fifth limit block 772 for preventing the third cross bar 77 from sliding left and right.

[0064] Therefore, before eating, the third cross bar 77 can be manually pushed to slide along the first slide groove 751 and the second slide groove 761, thereby driving the first transmission mechanism 2, the first pedal 3, the second transmission mechanism 5 and the second pedal 6 to move forward and backward, thereby achieving a rough adjustment of the forward and backward movement of the first clamp 1 and the second clamp 4 above the table top. The setting of the fourth limit block and the fifth limit block can improve the stability of the device during use.

[0065] According to the auxiliary hand-disabled dining table according to the embodiment of the present invention, the second pulley assembly includes a third pulley 56, a fourth pulley, a second steel wire rope, and a seventh connecting rod 54 horizontally arranged below the sixth connecting rod, the seventh connecting rod 54 is fixedly connected to the fifth connecting rod 52, the third pulley 56 is fixedly arranged at one end of the fourth connecting rod 51 close to the fifth connecting rod 52, and a fourth pulley is arranged at the position of the fifth connecting rod 52 and the seventh connecting rod 54, one end of the second steel wire rope is fixedly connected to the third pulley, and the other end passes around the fourth pulley and is connected to the second clamp 4, so as to drive the second clamp 4 to rotate in a vertical plane.

[0066] like Figure 3 As shown, according to the auxiliary dining table for hand-disabled people according to an embodiment of the present invention, the second clamp 4 includes an eighth connecting rod 61 located below the sixth connecting rod, a ninth connecting rod 62 located below the sixth connecting rod, and a third clamp 63 for fixing eating utensils, the third clamp 63 is hinged to the sixth connecting rod 53, one end of the eighth connecting rod 61 is sleeved in the seventh connecting rod 54 and connected to the second steel wire rope, one end of the ninth connecting rod 62 is hinged to the other end of the eighth connecting rod 61, and the other end is hinged to the bottom of the third clamp 63.

[0067] Specifically, the tableware for taking food is selected from any one of a fork or a spoon.

[0068] Specifically, a second compression spring is provided on the outer wall of the eighth connecting rod 62, a second compression spring is provided on the inner wall of the seventh connecting rod and the outer wall of the eighth connecting rod 61 respectively, and a third limit block and a fourth limit block for compressing and limiting the second compression spring are provided on the outer wall of the third adjusting rod 143 and the inner wall of the third connecting rod 23 respectively.

[0069] Thus, the disabled person applies force left and right along the plane where the second pedal 6 is located by his feet, so that the second clamp 4, i.e., the eating tableware, moves left and right, and moves it to above the position where the eating tableware is located. Then, the fourth connecting rod 51 rotates along its axial direction by stepping on the second pedal 6, driving the second pulley 56 to rotate, so that the second steel wire rope on the first pulley 56 contracts, and the second steel wire rope pulls the eighth connecting rod 61, the ninth connecting rod 62, and the third clamp 63 in turn, so that the third clamp 63 rotates downward in the vertical plane. At the same time, the second compression spring is further compressed, the first steel wire rope is relaxed, the second compression spring is reset, and the third clamp is reset. By controlling the size and direction of the applied force, the first connecting rod can be slowly rotated in the opposite direction along its axis, and the third clamp 63 can be rotated around the second elastic connecting piece, so that the eating and feeding operations of the eating tableware can be realized.

[0070] Specifically, the fork or spoon is connected to the third clamp 63 by bolts, thereby facilitating the disassembly and replacement of eating utensils of different specifications to adapt to the clamping of different foods, thereby improving the practicality of the device.

[0071] like Figure 4 As shown, according to the auxiliary hand-disabled dining table according to an embodiment of the present invention, the first elastic connecting member 24 includes a cylinder 241, a rod 242 and a spring 243. One end of the cylinder 241 is rotatably connected to the first auxiliary column 25, and the other end is sleeved with the rod 242. The cylinder 241 is connected to the rod 242 along its axial direction through a slide groove and a slider. A spring 243 is arranged in the cylinder, one end of the rod 242 is fixedly connected to the spring 243, and the other end is fixedly connected to the second connecting rod 22.

[0072] Since the cylinder 241 is connected to the rod 242 by the slide groove and the slider, when the disabled person applies a force forward or rightward to the plane where the first pedal 3 is located, under the action of friction, the first pedal 3 drives the first connecting rod 21 and the second connecting rod 22 to rotate, while the cylinder 241 and the rod 242 rotate around the axis direction of the cylinder 241, thereby realizing the tilting of the first clamp 1, i.e. the cup; when the first pedal 3 drives the first connecting rod 21, the second connecting rod 22 and the third connecting rod 23 to move left or right, the spring is subjected to subcontraction or extension, realizing the left and right movement of the first clamp 1 (i.e. the cup), and the first pedal 3 is released, the spring 24 is reset under the action of the restoring force, and the first clamp 1 returns to the initial position.

[0073] Based on the hand-assisted diet for the disabled of the present invention, the cups and eating utensils are pulled to the appropriate positions by pulling the steel wire rope to realize the eating and drinking actions of the disabled. The first clamp 1 is opened and the cup is placed in the first clamp 1 by the first pedal 3, so as to clamp the cup. The first pedal 4 is rotated to control the rotation angle of the first pulley 26, so as to pull the first steel wire rope and control the opening angle of the first clamp 1, so as to adapt to cups of different specifications; the first pedal is rotated to rotate around the axis where the first elastic connector 24 is located, so as to rotate the first clamp 1 and tilt the cup, so as to facilitate the disabled to drink water. Similarly, by stepping on the second pedal 6 on the right, the spoon or fork is realized to rotate up and down around the hinge between the third clamp 63 and the sixth connecting rod 53 in the vertical plane, move left and right in the horizontal direction, and rotate around the axis where the second elastic connector is located.

[0074] Although the embodiments of the present invention have been described in detail above, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and purpose of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
