CN218943784U - Pneumatic glove - Google Patents

Abstract

A pneumatic glove is provided, wherein each finger sleeve part formed by jointing a lamination and a hanging piece overlapped on the lamination is bent and stretched along with the actuation of a pneumatic telescopic assembly arranged on the back side of a hand, and the jointing part of the lamination and the hanging piece is formed on the back side and/or the palm side of the finger sleeve part. By forming the process joint of the finger sleeve portions, such as stitch seams formed by stitching together the laminate and the hanging sheet along a predetermined stitch seam, or by forming the melt-stitched edge joint on the back side and/or the palm side of the finger sleeve portions, rather than on the finger seam side between two adjacent finger sleeve portions, the lateral width of the laminate does not exceed the lateral width of the corresponding finger, or does not exceed the lateral width of the formed finger sleeve portions, and the interference of movement between each other can be effectively reduced. When the lamination and the hanging piece are stitched together along a preset stitching line, the width of the lamination along the transverse direction of the fingers does not exceed the width of the corresponding fingers, and the longitudinal length of the hanging piece is smaller than the lamination.

Description

Pneumatic glove

Technical Field

The utility model relates to the technical field of finger rehabilitation training, in particular to a pneumatic glove for rehabilitation training.

Background

In the conventional hand rehabilitation training system, as shown in fig. 1, the finger sleeve portions 31 of the pneumatic glove 30 are respectively fitted over the finger portions 41 of the hand 40 of the wearer, and are bent and stretched by actuation of a pneumatic expansion and contraction unit (not shown, see patent document 1: cn211835262u of the present applicant) provided on the back side of the back cover portion 32, or by bending and stretching of the fingers of the wearer.

After cutting out the back cover portion 32 from the base material, hanging pieces 36 having respective shapes are respectively stacked at lamination positions corresponding to the respective finger portions 41, and sewn along the sewing lines 33, thereby forming the respective finger sleeve portions 31. At this time, a leg portion is also formed between the peripheral edges of the lamination and the hanger and the stitch line 33. However, the two adjacent foot edges 34, 35 located in the finger slit often rub against each other, interfering with each other during flexion and extension movements of the adjacent two digits, especially on the root-leaning side of the digits, thereby affecting the use experience during rehabilitation training. By a finger slit is meant a gap between two adjacent fingers.

In order to solve the above problems, an object of the present utility model is to provide a pneumatic glove capable of effectively eliminating interference between adjacent finger sleeve portions during rehabilitation training by avoiding finger joints to form a foot edge portion.

According to an aspect of the present utility model, there is provided a pneumatic glove comprising a finger sleeve portion which is bent and stretched upon actuation of a pneumatic telescopic member provided on a back side of a hand, the finger sleeve portion being formed by joining a laminate and a hanging piece which covers the laminate, wherein, at least in the finger sleeve portion for a finger other than a thumb, a joining portion of the laminate and the hanging piece is formed on the back side and/or the palm side of the finger sleeve portion and is located at a position within a range of a lateral width of a corresponding finger or a position within a range of a lateral width of the corresponding finger sleeve portion.

Preferably, the lamination and the hanging piece are stitched together along a preset seam, and the formed seam is formed as a joint, wherein the preset seam is respectively a first seam, a second seam and a third seam and a fourth seam which extend along the longitudinal direction of the lamination.

Preferably, the transverse width between the third and fourth seams of the laminate is no more than the transverse width of the corresponding finger, or the transverse width of the formed finger sleeve portion.

Preferably, the longitudinal length of the tab is less than the laminate such that the formed finger sleeve portion terminates midway from the finger end portion to the finger root portion.

Preferably, the laminate has a tapered width from the base of the finger to the point of engagement with the tab.

Preferably, an elastic material layer is further attached to the finger root side of the hanging piece to form a reduced mouth portion of the finger sleeve portion.

Preferably, an opening is provided at a joint of the hanging piece corresponding to the finger.

Preferably, the respective peripheral edges of the laminate and the suspension tab are pressed against each other such that the formed joint is formed on the dorsal and/or palmar side of the finger sleeve portion.

Preferably, the finger sleeve portion is formed with a single joining portion from a single piece of base material by melt-bonding.

Preferably, in a plan view of the pneumatic glove, the finger sleeve portion has a contour line, the projection of the engagement portion on the plane of the contour line being spaced apart from the contour line.

As the fixing part of the wrist, a sticking component which is respectively a hook surface and a rough surface of the magic tape is sewn at the fixing part corresponding to the wrist.

According to the present utility model, by forming the process joint of the finger sleeve portions, such as the stitch seam and its corresponding foot edge, or the melt-pressed edge joint, on the dorsal and/or palmar sides of the finger sleeve portions, rather than on the sides of the finger seam between adjacent two finger sleeve portions, the interference of movement with each other can be effectively reduced.

The specific meaning of the terms in this application will be understood by those of ordinary skill in the art as the case may be.

According to the pneumatic glove of the embodiment of the present utility model, at least on the adjacent side of any two of the four finger sleeve portions 1 other than the thumb, the joint between the laminate and the hanging sheet is not on the finger slit side but on the back side and/or the stomach side.

< first embodiment >

The following description will be given by taking a configuration example of the finger sleeve portion 1 corresponding to the middle finger (the same applies to other fingers including thumb) in the case where a suture line is formed on the back side of the finger.

Fig. 3 shows a two-layer substrate made of, for example, a three-layer fabric material such as N cloth, OK cloth, etc. for sewing the finger sleeve part 1: a laminate 11 corresponding to a finger portion in the back of hand covering portion 10 (see fig. 2) cut out from the base material, and a hanging sheet 12 for overlapping the laminate 11. The width of the hanging sheet 12 is larger than the width of the lamination 11 in the finger transverse direction (transverse to the longitudinal direction of the finger). In particular, the distance B between the tab stitches corresponds to the preset stitch extending longitudinally along the tab, i.e. the first stitch 15, the second stitch 16, the lateral width F of the finger (see fig. 1) corresponds to the lateral width of the user's finger of the specification to which the finger sleeve portion 1 is adapted, and the distance W between the lamination stitches corresponds to the preset stitch extending longitudinally along the lamination, i.e. the third stitch 13, the fourth stitch 14.

The third and fourth stitches 13, 14 of the laminate 11 and the first and second stitches 15, 16 of the hanging piece 12 constitute positions where the laminate 11 and the hanging piece 12 are sewn to each other in the lateral both-side direction of the finger. For example, when the lateral sides of the hanging piece 12 are folded along the folding lines 17, the hanging piece 12 can be sewn to the third and fourth sewing lines 13, 14 along the first and second sewing lines 15, 16, thereby forming the joint portion 2 shown in fig. 5. Here, the width between the third stitch line 13 and the fourth stitch line 14 is smaller than the lateral width F of the corresponding finger, so that the third stitch line 13 and the fourth stitch line 14 are located at positions within the lateral width F of the corresponding finger or at positions within the lateral width M (see fig. 7) of the finger backside of the finger sleeve portion 1. In this way, the stitch lines formed between the tab 12 and the laminate 11 at the positions of the third stitch line 13 and the fourth stitch line 14 do not exceed the lateral width M of the finger back side of the finger sleeve portion 1, so that the joint portion 2 of the tab 12 and the laminate 11 is formed on the finger back side. The lateral width M of the back side is generally substantially the same as, but not limited to, the finger-side, so long as the above positional and dimensional relationships are equally applicable to those formed on the finger-side.

In the plan view of fig. 5, the sleeve portion 1 has a contour line 38 at the outer peripheral edge portion, and the projection (broken line) of the joint portion 2 on the plane of the contour line 38 is spaced apart from the contour line 38 by a distance G. The distance G is preferably substantially constant but is not limited thereto.

Optionally, the lateral width of the laminate 11 (=the width W between the third stitch line 13 and the fourth stitch line 14+the stitch width of the first leg portion 20×2) does not exceed the lateral width F of the corresponding finger 27 or the lateral width M of the finger backside of the formed finger sleeve portion 1. The stitch width of the first leg portion 20 may be set in consideration of the corresponding specification of the finger sleeve portion 1, the stitch at the stitch, and the like.

Thus, no seam trace exists in the finger seam, but only the outer surface of the hanging piece 12 is smooth, so that the motion interference caused by the joint part formed by stitching between two adjacent fingers can be effectively eliminated.

The outline 19 of the tip portion of the hanging piece 12 may be formed into a head space structure suitable for the finger sleeve portion 1 together with the outline 18 of the tip portion of the lamination 11, and the description thereof will be omitted here.

As shown in fig. 5, the longitudinal length N of the hanging sheet is smaller than the longitudinal length H of the lamination sheet, so that the formed finger sleeve portion is terminated midway from the finger end to the finger root to reduce finger stall accumulation on the palm side during the flexion and extension actions.

According to a particular embodiment, the third 13 and fourth 14 sutures may coincide with each other, i.e. the hanging piece 12 is directly sewn to the laminate 11 along a longitudinal suture, as shown in fig. 9.

According to another particular embodiment, the preset stitching is not limited to the two preset stitching 13, 14 described above, but may be provided for other stitching purposes (for example, the installation of pneumatic assemblies), but since the transverse width of the laminate 11 does not exceed the width of the corresponding finger, these stitching fall within the transverse width of the laminate 11, or within the envelope of the third stitching 13, 14, so that stitching exceeding the width of the finger and the first and second foot portions 20, 21 are not formed. Moreover, the finger sleeve part which is fixed by suture is convenient and simple, firm and durable and has low cost.

In this way, during wear training, the finger seam locations between adjacent finger sleeve portions are no longer present at the edges of the foot as in the prior art, but rather are smooth, continuous, substrate material, no longer causing significant friction with one another, and correspondingly eliminating interference with one another as they move.

The lamination and the hanging sheet are overlapped with each other as an example in the above description, but the present utility model is not limited thereto, and the sewing line of the hanging sheet and the lamination may be directly set as the edge line of the two sheets, and the edge line positions of the two sheets may be directly sewn as the sewing line, instead of just overlapping each other as needed.

The constitution of the finger sleeve portion according to the first embodiment of the present utility model has been described above, and the pneumatic telescopic unit 26 (see fig. 6 and 7) for driving the finger sleeve portion 1 to bend and extend, such as a connection air pipe, a bellows, and an air pipe unit, will not be described.

< second embodiment >

The following will describe an example in which the joint is formed on the finger pad side.

The joint between the laminate and the hanging sheet is somewhat different on the finger belly side than in the case of the back side of the finger in the first embodiment described above, as well as the glove form. Since the width of the laminate 11 is smaller than the hanging sheet 12 when the stitch position is located on the dorsal side of the finger, the stitch position can be easily secured on the dorsal side of the finger, and the laminate parts corresponding to the five fingers can be directly fed together.

When the suture location is on the side of the finger, either simultaneously or only, it is often desirable that the width of the laminate 11 be greater than the width of the hanging sheet 12 and greater than the lateral width of the finger. At this time, because the space between the fingers is limited, the five fingers are difficult to be directly fed together. One expedient is to feed each finger separately and then attach it to the glove (e.g. the substrate corresponding to the palm) by means of gluing, stitching or the like.

On the other hand, in order to spread the cut material from the cloth plane as much as possible and then stitch the cut material together and integrally form the glove, a cut pattern as shown in fig. 8 may be considered. Wherein the dashed lines of the middle finger portion correspond to the periphery of each finger laminate in the first embodiment (i.e., corresponding to the solid line periphery of each finger laminate in fig. 2), and the solid lines represent the contour lines when each laminate is cut from the substrate. For example, compared with the first embodiment, with the index finger laminate, the cloth of the tiger mouth part is fully utilized, and the left side contour line relative broken line offset R < the right side contour line relative broken line offset R, so that not only the width dimension of the index finger laminate but also the width dimension of the middle finger laminate can be enlarged. Likewise, for middle finger laminates, the left side contour relative to the dashed offset Q < the right side contour relative to the dashed offset Q allows not only the width dimension of the middle finger laminate to be enlarged, but also the width dimension of the ring finger laminate to be enlarged. Likewise, for ring finger laminates, the right side contour relative dashed offset P corresponding to index finger, middle finger laminate offset R, Q may be set, since a larger offset space for the little finger is no longer necessary at this time, which is sufficient to set the left side contour relative dashed offset O larger, considering that the substrate area outside the little finger may be utilized. The suture line can be formed on the belly side of the finger by correspondingly setting the hanging piece size of each finger. For example, taking the index finger as an example, among the fifth suture line 27 and the sixth suture line 28, the sixth suture line 28 is located within the dotted outline 29 corresponding to the back of the index finger, and the fifth suture line 27 will be located on the belly side of the index finger when the index finger laminate is properly folded. Depending on the setting of the offset R, Q, P, O, the suture thread may be formed on both the dorsal side and the dorsal side. Therefore, the stitch seam is not existed in the finger seam, but is only the outer surface of the smooth hanging piece 12 (or one side is the lamination 11 and the other side is the hanging piece 12), thereby effectively eliminating the problem of motion interference between two adjacent fingers caused by the joint position.

Likewise, the stitching of the laminate and the hanging piece may or may not be sewn to each other or with a small overlap area, thereby forming a joint between the laminate and the hanging piece.

< junction site >

The joint between the laminate and the hanging piece is illustrated in fig. 1 as the leg portions 34, 35 (including the seam lines corresponding to the seam lines 33) between the peripheral edges of the laminate and the hanging piece 36 and the seam lines 33, which are shown as flat seams where the two flat surfaces of the laminate and the hanging piece overlap and are sewn along the seam ends left at the edge portions. The first leg portion 20 and the second leg portion 21 (including the stitch corresponding to the first stitch 15 and the second stitch 16) are illustrated in fig. 3 and 4 by overlapping the two layers of the laminate and the hanging sheet by Xcm (for example, x=0.3 to 0.5 cm), and by centering the two layers of the laminate and the hanging sheet. The leg portion between the periphery of the hanging sheet 12 (or the laminated sheet 11) and the first and second sewing threads 15, 16 is also called a seam portion, and the seam amount required for the seam locking is taken into consideration. Therefore, the seam is flat and thin, no peduncles are generated, the exposed area of the piece seam head can be reduced, and the peripheral edge of the piece seam head can be in a lockstitch mode in advance. And the seam parts can be overlapped together for edge locking after sewing.

However, the seam type of the joining seam for forming the joining portion is not limited thereto, and other suitable means such as stitching, deseaming, bright wrapping, dark wrapping, etc. may be selected as required by those skilled in the art.

< other examples >

The above description has been made by taking the example of the stitch, but the present utility model is not limited thereto, and even in the case of other finger sleeve parts manufactured by other processes such as dipping and melt-bonding, the joint portions near the outer peripheral edge may be formed on the back side and/or the palm side instead of the finger seam side, and in this case, the raw materials on both sides of the joint portions are regarded as equivalent to the laminate and the hanging sheet for the sake of easy understanding. Alternatively, the finger sleeve portion having only one joining point may be formed by melt-bonding only one piece of the base material. The sheet of substrate may be preformed to have a combined shape corresponding to the laminate and hanger described above.

Optionally, an opening 22 may be formed at each joint of the hanging piece 12 corresponding to the finger, so that the wearing is more fit, so as to reduce the wearing resistance of the fingerstall structure and the wrinkles generated during the flexing motion of the finger. The opening portion 22 is preferably formed to have a larger lateral width than a longitudinal width, for example, an elliptical opening or a circular shape. The maximum inner diameter of the opening 22 is smaller than the maximum inner diameter of the finger cuff structure.

The sewing thread along the sewing thread can be replaced completely or partially, and the pasting mode is adopted, at the moment, at the corresponding sewing thread position, pasting components, such as hook surfaces and hair surfaces of the magic tape, can be sewn on the preset sewing threads of the lamination and the hanging piece in advance.

Optionally, an elastic material layer 23 is further attached to the finger root side of the hanging piece 12 to form a pinch portion of the finger sleeve portion, so as to be attached to the finger with proper force, and effectively prevent the finger rehabilitation training finger from being detached from the finger sleeve portion.

As shown in fig. 2 and 5, for example, as the first fixing member 24 and the second fixing member 25 of the wrist, an adhesive unit having hook surfaces and loop surfaces of a velcro may be sewn in correspondence with fixing portions corresponding to the wrist.

In addition, in order to further reduce possible motion interference, the part of the lamination 11 between the root of the finger and the joint of the hanging piece 12 can be provided with a tapered width, so that the width of the joint of the lamination 11 and the hanging piece 12 is larger than that of the joint of the lamination, the installation and protection of the pneumatic telescopic assembly on the back side of the finger are facilitated, and the possible motion interference can be reduced.

While the utility model has been described with reference to various specific embodiments, it should be understood that numerous changes could be made within the spirit and scope of the inventive concepts described. Accordingly, it is intended that the utility model not be limited to the described embodiments, but that it have the full scope defined by the language of the following claims.
