Abstract

PROBLEM TO BE SOLVED: To provide a motor-driven glove wearing apparatus requiring no exhaustion mechanism.SOLUTION: A tip of a lever 24a of a one-way notch mechanism 24 is disengaged from a slider recess 34 when the front side of the lever 24a is raised. A slider 30 is then driven to a direction in which it is pushed out by a support frame 20 by energizing force of tension springs 33, 33. This movement enlarges an inner space of a bellows 25 in the support frame 20 and an inner space of the slider 30 so as to generate negative pressure inside. A glove which is put on an opening end of the slider 30 is pushed by atmospheric pressure due to the negative pressure of the inside and drawn into the slider 30, and further inflated in response to the negative pressure. An open hole 21 on the bottom of the bellows is closed by the negative pressure so as to maintain the negative pressure.SELECTED DRAWING: Figure 2

Description

  The present invention relates to a glove wearing apparatus for wearing rubber gloves.

Gloves made of elastic resin and rubber are routinely used in various fields. Regardless of the material, airtight gloves are generally referred to as rubber gloves.
Because rubber gloves with high adhesion take time and effort to install, open the rubber gloves in an airtight manner at the cylindrical opening of the bottomed cylindrical case and supply a negative pressure to the case. The glove wearing apparatus is used to generate negative pressure around the rubber gloves and inflate the rubber gloves.

  As described above, in order to supply the negative pressure in the case, in the glove wearing apparatus shown in Patent Document 1 and Patent Document 2, it is necessary to operate the exhaust device by the motor or to generate the negative pressure manually.

International Publication No. 2008-038438 JP-A-53-63789 Japanese Patent Application Laid-Open No. 2002-065696

The exhaust system is convenient but requires a power source, so it is limited in the installation location, and even if it is equipped with a battery, it takes time for replacement and charging. In addition, the size and cost of the exhaust system itself are also problems.
According to Patent Document 3, it is necessary to insert the other hand into the container while performing the pressing operation with one hand at the time of mounting operation, and it is bothersome to operate with both hands at the same time and by a person who can not insert with one hand. If you can not even wear. Since it is necessary to push with one hand while pushing with one hand, it will necessarily be pushed down vertically. In the oblique direction, the main body is moved by the pushing force. That is, the installation direction is necessarily limited.
In addition, you must remove the attached gloves from the container by your own operation.
The present invention provides a more convenient glove wearing apparatus.

  The present invention has a bottomed cylindrical outer case, and an opening portion of a glove which is slidable with respect to the inner peripheral surface of the outer case and which is generally cylindrical and protrudes from the outer case. Inner surface of the inner case airtightly communicating with the inner case of the inner case, a biasing mechanism urging the inner case in a direction to push out the inner case in the slidable range in the outer case, and the inner space of the inner case When the inner case and the outer case are separated, the volume of the inner space is increased, and when the inner case and the outer case are brought close, the volume of the inner space is reduced, and the biasing mechanism resists. And a notch mechanism for holding and releasing the inner case relatively at the back position of the outer case, and a valve mechanism for maintaining and releasing the positive pressure and the negative pressure in the airtight case.

In the above-mentioned configuration, the inner case is slidable with respect to the inner peripheral surface of the outer case, and is formed in a substantially cylindrical shape, and the opening portion of the glove can be attached at a portion protruding from the outer case.
The biasing mechanism is capable of biasing the inner case in a slidable range in the outer case in a slidable range, so that the inner case is released while the positive pressure in the airtight case is released by the valve mechanism. When it is moved to the back side in the slidable range in the case, the volume of the internal space of the airtight case is reduced, but the positive pressure in the airtight case is released. In this state, the inner case can be held relatively at the back side position of the outer case against the biasing mechanism by the notch mechanism. Next, the inside of the airtight case is disconnected from the outside by a valve mechanism, and the opening portion of the glove is attached to a portion of the inner case that protrudes from the outer case. Then, the inside of the glove, the inside of the inner case, and the inside of the airtight case become a communicating space and become disconnected from the outside world.

  In this state, when the inner case is released from the back side position of the outer case by the notch mechanism, the inner case is moved in the direction of pushing out in the slidable range in the outer case by the biasing mechanism. Therefore, the volume of the internal space of the airtight case is expanded to form a negative pressure in the airtight case. The airtight case and the inner case communicate with each other, and as a result, negative pressure is supplied to the inside (the side which does not communicate with the outside air) of the glove airtightly attached to the opening of the inner case. Then, the gloves are sucked into the inner case and expand in the inner case. In this state, the wearer's hand can be easily inserted into the glove. In this state, when the hand is pushed in and the inner case is moved to the inside of the outer case, the negative pressure in the airtight case becomes smaller, the pressure in the airtight case changes to a positive pressure, and the positive pressure As a result, the valve mechanism is automatically opened, the inside of the airtight case is the same as the outside pressure, and the glove is in close contact with the wearer's hand. The wearer withdraws the hand from the inside of the inner case to complete the work of wearing the gloves.

According to the present invention, the inner case is relatively pushed into the outer case against the biasing mechanism, and then a negative pressure can be formed inside the inner case simply by releasing the state by the notch mechanism, and the exhaust using the motor It is possible to provide a glove wearing apparatus which does not require a mechanism.
In addition, since the operation for generating the negative pressure is not performed simultaneously with the insertion operation, the biasing direction at the time of pressing is not limited to the vertically downward direction, and may be an oblique direction. Then, a degree of freedom is obtained in the insertion direction of the glove, and it becomes possible to turn it obliquely downward for easy insertion.

Hereinafter, embodiments of the present invention will be described based on the drawings.
FIG. 1 is a perspective view of a glove donning apparatus according to an embodiment of the present invention. Moreover, FIGS. 2-5 has shown each part by the partially broken figure.
In the drawing, a support frame 20 serving as an outer case is fixed to a pedestal plate 10, and a slider 30 serving as an inner case is supported by the support frame 20. The support frame 20 and the slider 30 both have a substantially elliptical cross section, the support frame 20 has a cylindrical shape with a bottom, and the slider 30 has a cylindrical shape. Although the slider 30 also has a wall surface at the back of the cylinder and is close to a bottomed state, the air wall 31 is formed at the back wall of the slider 30 and communicates with the internal space of the support frame 20 . In addition, a bellows 25 is disposed in the support frame 20. The bellows 25 communicates with the cylindrical slider 30 and expands and contracts as the slider 30 moves in the slidable range in the support frame 20. Specifically, when the slider 30 and the support frame 20 are separated, the volume of the internal space is expanded, and when the slider 30 and the support frame 20 are close to each other, the volume of the internal space is reduced. The bellows 25 corresponds to an airtight case.
On the other hand, the bellows 25 is a bottomed cylindrical shape having a bottom formed in a cylindrical body, but the bellows bottom portion open hole 21 is formed on the wall surface on the back side, and the outer case is on the wall surface on the back side of the support frame 20 facing An open hole 28 is formed. On the outer surface side of the support frame 20, a spring-loaded hinged valve 29 is attached, which communicates or shields the inside and the outside through the bellows bottom open hole 21 and the outer case open hole 28. When the spring-loaded hinged valve 29 is opened, the inside of the bellows 25 and the slider 30 communicate with the outside. As described later, the spring-loaded hinged valve 29 in the present embodiment pushes the slider 30 and when the bellows 25 and the inside of the slider 30 become positive pressure (a state in which the pressure is higher than the outside air is called positive pressure, Is called a negative pressure) and opens at other than positive pressure. The bellows bottom open hole 21, the outer case open hole 28 and the spring-loaded hinged valve 29 correspond to a valve mechanism for maintaining and releasing the positive pressure and the negative pressure in the airtight case.
Here, the support frame 20 corresponds to a bottomed cylindrical outer case, the slider 30 is slidable with respect to the inner peripheral surface of the outer case, and is formed in a substantially cylindrical shape from the outer case It corresponds to the inner case which can be attached to the opening part of the glove at the protruding part. Further, the bellows 25 and the slider 30 are in airtight communication with the inner space of the inner case, and when the inner case and the outer case are separated in the slidable range, the volume of the inner space is expanded. When the inner case and the outer case are close to each other, the volume of the inner space is reduced, which corresponds to an airtight case.

  As shown in FIG. 1, the support frame 20 has a case shape extending downward from the rear side wall, and is fixed to the pedestal plate 10 at the lower end. At this time, the support frame 20 is supported by being inclined so that the front end is at a higher position with respect to the horizontal surface than the rear end. In this way, it is possible to hold a posture that makes it easy for a person wearing a glove to insert a hand.

  As shown in FIG. 3 and FIG. 4, the outer peripheral shape of the slider 30 matches the inner peripheral shape of the support frame 20 to the extent that it can slide in a predetermined range in the length direction. The gap is formed to be as small as possible, and although it is not perfect, it is designed to be sufficiently airtight. In order to limit the range in which the slider 30 can slide, two grooves (spring stroke travel guide grooves) 22 and 22 are formed in parallel to the length direction on the lower surface of the support frame 20. The slider-side spring fixing pins 32 and 32 are formed so as to protrude outward from the inside of the support frame 20.

  One end of the tension springs 33, 33 is engaged with the slider-side spring fixing pins 32, 32, and the other ends of the tension springs 33, 33 project downward from the near side of the lower surface of the support frame 20. It is locked to the frame side spring fixing pins 23, 23. The tension springs 33, 33 urge the slider 30 toward the front side with respect to the support frame 20, and its shape and length so that the slider 30 can be pushed backward with respect to the support frame 20. Is determined by adjusting the In other words, the tension springs 33 and 33 do not sag even at a position where they are pulled out to the front side with respect to the support frame 20 in the movable range of the slider 30, and push the slider 30 back to the support frame 20. It does not extend completely and loses its biasing force.

  As described above, the slider 30 as the inner case is made by locking one end of the tension spring 33 to the slider side spring fixing pins 32 and 32 and the other end to the slider side spring fixing pins 23 and 23. It urges in the direction of pushing out in the slidable range in the support frame 20 which is the outer case, and constitutes an urging mechanism.

  A one-way notch mechanism 24 is formed on the lower surface of the support frame 20. The one-way notch mechanism 24 is formed of a lever 24a, a pin 24b, a spring 24c, two plate-like support bracket portions 24d and 24d projecting downward, an opening 24e and the like, and the lever 24a is two plate-like supports It is penetrated by the pin 24b in a state of being sandwiched between the bracket parts 24d and 24d, and is rotatably supported, and the spring 24c biases the front side of the lever 24a to push downward. As a result, the rear end of the lever 24a enters into the inside of the support frame 20 via the opening 24e and abuts. A slider main body notched slider recess 34 formed on the lower surface of the slider 30 is formed at the end of the abutment. The slider recess 34 is formed at a predetermined position, and the tip end of the lever 24 a climbs over the slider recess 34 when pushing the slider 30 but locks when the slider 30 tries to move in the reverse direction. When the end on the front side of the lever 24a is pulled up against the spring 24c, the lock between the end on the back side of the lever 24a and the slider recess 34 is released, and the biasing force of the tension springs 33 and 33 causes the slider 30 is a mechanism to be pulled back to the front side.

As described above, one way is to be able to hold and release the slider 30, which is the inner case, relatively at the back position of the support frame, which is the outer case, against the biasing mechanism composed of the tension springs 33, 33 and so on. The notch mechanism 24 constitutes a notch mechanism.
In the present embodiment, the slider recess 34 is formed at a predetermined position, but it may be possible to lock at an arbitrary place by forming a saw blade-like portion over a certain range, for example. Also, the configuration of the one-way notch mechanism 24 can be modified to other shapes that serve similar purposes.

  As shown in FIG. 2, in the present embodiment, since the spring stroke travel guide grooves 22 and 22 and the opening 24 e are formed, the support frame 20 can not be airtightly isolated inside and outside. For this reason, the inside of the bellows 25 is set as the internal space of the support frame 20 substantially. The bellows 25 airtightly connects the front side to the wall surface on the back side of the slider 30 and airtightly connects the rear side to the back wall of the support frame 20. That is, the bellows 25 itself has a cylindrical shape with a bottom, and the front opening is connected to the cylindrical slider 30 to form a series of spaces which can be expanded and contracted.

  The bellows 25 is disposed between the inner case and the outer case, and corresponds to a part of a stretchable airtight case communicating with the inner case inner space.

  As shown in FIG. 2, a support frame side confirmation window 26 formed of a transparent plate is formed on the upper surface on the support frame 20 side, and a slider side confirmation window formed on the upper surface of the slider 30 on the upper surface 36 is formed. When the slider 30 is pushed into the back side of the support frame 20, the support frame side confirmation window 26 and the slider side confirmation window 36 overlap so that the inside can be viewed from the outside through the transparent plate. In addition, when the slider 30 is pushed out most from the support frame 20, the slider-side confirmation window 36 does not overlap the support frame 20, and the inside can be viewed alone through only the slider-side confirmation window 36.

  As shown in FIGS. 2 to 5, a hook-like support frame side protrusion 27 extending in the length direction is formed on the inner peripheral surface on the opening side of the support frame 20, and on the inner peripheral surface on the opening side of the slider 30. A groove 37 extending in the length direction in which the support frame side protrusion 27 can enter is formed. When the slider 30 is in the state of being most inward of the support frame 20, the open end of the slider 30 and the open end of the support frame 20 become substantially flush. As described later, the open end of the slider 30 is covered with the open end of the glove. The open end portion of the glove (opening portion) does not enter the groove 37 due to its elasticity. However, in the process of pushing the slider 30 into the inside of the support frame 20, the support frame side protrusion 27 abuts on the end of the rubber glove that is covered so as to cover the groove 37. As it is further pushed in, the support frame side projection 27 gradually moves the end of the glove to the opening end of the slider 30 and finally removes it from the slider 30. The support frame side protrusion 27 effectively works so as not to get caught in the gap between the slider 30 and the support frame 20 when the hand is pushed.

  As shown in FIG. 5, although the slider 30 is formed in a tubular shape, the portion near the opening end is formed by dividing the wall surface. The cross section of the opening is generally an oval, and the upper surface side is integrally formed with the back side of the cylinder. However, the lower surface side is divided into a gull wing 38a with pins from the curved surface on the left side to the lower straight portion and a pinless gull wing 38b from the curved surface on the right side to the lower straight portion. The pin gull wing 38a and the pin no gull wing 38b are also connected to the wall face on the top face at the end on the curved face side by spring hinges 38a1 and 38b1, and are rotatable within the cross-sectional plane of the open end. The spring hinges 38a1 and 38b1 bias the gull wing 38a with pin and the gull wing 38b with pin inward in the opening direction, so the end of the straight portion is the wall surface on the upper surface side as shown in FIG. It is close to the In this state, the outer peripheral length of the opening end of the slider 30 is reduced. As will be described later, the open end of the glove is placed on the open end of the slider 30, but the smaller the outer peripheral length is, the smaller it is when expanding the open end of the glove and work becomes easier.

  If the gull wing 38a with pins and the gull wing 38b with pins are pushed and spread against the spring hinges 38a1 and 38b1, the open end of the slider 30 has the same shape as the back cylindrical portion. At this time, as shown in FIG. 6, the edges of the pinned gull wing 38 a and the non-gulled wing 38 b are pressed to the inside of the edge of the slider 30. A gull wing seal 38c is attached to this portion, and when pressed, it is easy to ensure airtightness.

As shown in FIGS. 7 and 8, a pin 38d movable in the longitudinal direction is accommodated at the end of the pin-mounted gull wing 38a. The tip of the pin 38d is internally biased so as to protrude rearward.
A through hole 38d1 substantially coinciding with the depth direction of the slider 30 is formed inside the wall material at the end of the gull wing 38a with a pin, and in the through hole 38d1, a pin 38d whose tip is tapered and a spring The pin 38d is accommodated with the screw 38d2, and further, the pin 38d is connected to the screw 38d4 and the operation element 38d5 through an elongated hole 38d3 communicating with the outer peripheral surface of the gull wing 38a. Since the front side is sealed in the through hole 38d1 and the spring 38d2 is accommodated on the sealed side, the spring 38d2 biases the pin 38d in the direction of pushing it out.

  However, since the screw 38d4 connected to the pin 38d can be moved only in the range of the length of the long hole 38d3, the pin 38d is not completely pushed out of the through hole 38d1, and only the tip is shown in FIG. It protrudes and the remaining part is always held in the through hole 38d1. Further, as shown in FIG. 8, it is also possible to pull back the pin 38d into the through hole 38d1 in the range of the length of the long hole 38d3. When it is desired to release the lock, the operator 38d5 is operated to pull the pin 38d back into the through hole 38d1.

  The tip of the pin 38d is an inclined surface, and this inclined surface is in front of the hole 38d6 formed on the wall surface of the upper surface of the slider 30 as shown in FIG. When it abuts on the formed slope 38d7, the guiding direction is such that it is pushed into the through hole 38d1. Once it passes over the inclined surface 38d7 and faces the hole 38d6, the tip of the pin 38d enters the hole 38d6 by the biasing force of the spring 38d2, and the gull wing 38a with pin can be locked to the wall surface of the upper surface of the slider 30. In the state where the gull wing 38a with pins and the wall surface of the slider 30 are locked, the slider 30 is inhibited from returning to the diameter reduction state from the position of the diameter expansion state.

Thus, the cylindrical peripheral wall surface is divided in the vicinity of the end in the longitudinal direction of the inner case which is the slider 30 (pin gull wing 38a and pin no gull wing 38b), and rotation parallel to the longitudinal direction as a cylindrical body A shaft (spring hinges 38a1 and 38b1) is provided, and the peripheral wall surface is rotatable inward with the same rotation shaft as a support shaft.
As a result, the part of the inner case that protrudes from the outer case is a tubular shape having a longitudinal direction and a short direction, and the thickness can be changed in the short direction.
The opening end of the slider 30 is fitted with an anti-slip anti-slip 41 for gloves. This is to prevent the glove from being drawn more than necessary when the entire glove is drawn inside the slider 30 after the glove is attached to cover the open end of the slider 30 as described later. When a glove is attached so as to cover the opening end of the slider 30 so that a gap does not easily occur, leakage of negative pressure is reduced.

  In this embodiment, the opening end of the slider 30 is divided into the wall surface on the upper surface side and the wall surface on the lower surface side, and the wall surface on the lower surface side is deformed to narrow the opening width of the portion of the inner case protruding from the outer case. The opening width adjusting mechanism is configured to change to a diameter reduction state and a wide diameter expansion state of the opening width. However, it is also possible to divide the open end of the slider 30 in the longitudinal direction and to deform so that one slides in the longitudinal direction to widen or narrow the opening width. Also, although the pin 38d of the gull wing 38a with a pin is locked in the hole 38d6, it is needless to say that the same function can be configured by another locking mechanism.

  In the above-described configuration, in the operation of wearing a glove made of rubber, resin or the like, as shown on the upper side of FIG. In this state, the operator pushes the slider 30 into the back side of the support frame 20. When the slider 30 is pushed most against the tension springs 33, 33, the tip of the lever 24a in the one-way notch mechanism 24 locks in the slider recess 34. At this time, the open end of the slider 30 protrudes more than the open end of the support frame 20.

  Next, the operator puts the open end of the glove on the open end of the slider 30 while stretching it to the left and right. Since the pin-in gull wing 38a and the no-pin gull wing 38b at the open end of the slider 30 are not in the expanded state, the length at which the open end of the glove has to be extended can be short. Easy to wear. When the open end of the glove can be covered, the gull wing with pin 38a is pushed down with the fingertip from the outside of the glove. The pinned gull wing 38a is formed longer than the pinless gull wing 38b, and as shown in FIG. 5, the tip of the pinned gull wing 38a is inside the tip of the pinless gull wing 38b.

  Therefore, the gull wing 38a with pins is pushed down with a fingertip. The tip of gull wing 38a with pin also pushes the tip of pin no gull wing 38b downward from the inside, and both gull wing 38a with pin and gull wing 38b move downward and form a wall surface similar to the top wall Lead to Of course, this operation gradually increases the outer peripheral length of the opening end of the slider 30, and the opening end of the glove is also spread from the inside. When the tip of the gull wing 38a with pin is in a state of overlapping with the wall surface of the back of the slider 30, as described above, the pin 38d enters the hole 38d6 and locks. Thereby, the gull wing 38a with a pin and the gull wing 38b with a pin become cross-sectional shape substantially the same as the wall surface by the side of an upper surface, and the slider 30 forms the surrounding surface similar to the cylinder by the side of back.

In this state, the internal space of the bellows 25 in the support frame 20 and the internal space of the slider 30 are in communication with each other and are integral with each other. Furthermore, since the open end of the slider 30 is covered with gloves, the space is an airtightly closed space.
Next, when the front side of the lever 24 a of the one-way notch mechanism 24 is pulled up, the tip of the lever 24 a is disengaged from the slider recess 34. Then, the slider 30 is driven in the direction of being pushed out of the support frame 20 by the biasing force of the tension springs 33, 33. Since this movement enlarges the internal space of the bellows 25 in the support frame 20 and the internal space of the slider 30, negative pressure is generated inside. The negative pressure inside causes the glove placed on the open end of the slider 30 to be pushed by the pressure of the outside air, drawn into the inside of the slider 30, and further expanded according to the negative pressure. However, since the glove 30 is fitted at the opening end of the slider 30 to prevent the glove from being pulled out, even if the entire glove is drawn inside the slider 30, it is prevented from being pulled out from the opening end of the slider 30. it can. In addition, when a negative pressure generate | occur | produces, the bellows bottom part open hole 21 closes and maintains a negative pressure.

  In this inflated state, the operator inserts a hand from the open end of the glove. The glove is expanded in the slider 30, so that the operator can easily insert the glove up to the fingertip. Even if the gloves are worn on the fingertips, perform the operation to push the hand still. Then, since the fingertip abuts against the wall surface on the back side in the slider 30, the slider 30 is further pushed with the fingertip. Since this movement reduces the internal space of the bellows 25 in the support frame 20 and the internal space of the slider 30, the internal negative pressure decreases and the glove fits the operator's hand. . In addition, since the open end of the slider 30 enters the open end of the support frame 20, the support frame side protrusion 27 starts to abut on the end of the rubber glove covered so as to cover the groove 37 and is further pushed. The support frame side projection 27 gradually moves the end of the glove to the open end of the slider 30 and finally removes it from the slider 30.

  When the open end rubber glove of the slider 30 is removed, the internal space of the bellows 25 in the support frame 20 and the internal space of the slider 30 communicate with the outside air. In addition, the slider 30 is sufficiently pushed into the support frame 20, but when the operator starts pulling out the hand, the slider 30 gradually returns to the front side. However, as described above, the lever 24 a of the one-way notch mechanism 24 stops at the position where it is locked to the slider recess 34.

Thereafter, at this position, the opening end of the slider 30 is resumed from the operation of putting the gloves on again.
As described above, the present invention has developed a small and lightweight "manual glove-attaching device" that can be easily used by anyone without using a power device requiring a power source.
The main driving force of this device is a "tension coil spring". The negative pressure is created by the repulsive force of the tension spring 33, and after the glove is adsorbed, the adsorption state is maintained long by reliably sealing so that the outside air does not intrude into the negative pressure part from between the parts constituting the device Ru.
The tension springs 33, 33 are disposed outside the lower surface side of the support frame 20. However, the compression springs 33a, 33a shown by the two-dot chain line in FIG. The slider 30 may be urged in the direction of pushing the slider 30 against the support frame 20 using repulsion.

After inserting the hand, the opening end of the slider is pushed by the support frame side protrusion 27 at the end of the support frame 20 by pushing it back until the glove is released while resisting the reaction force of the tension spring 33 and the support frame It is automatically removed by plunging into the end of the 20 open end.
At this time, the one way notch mechanism 24 is not engaged. When the hand is pulled out of the slider 30 with the glove attached, the slider 30 is automatically notched by the one-way notch mechanism provided on the support frame 20. (Tension spring 33 remains in tension)

After setting the next glove on the opening end of the slider 30, the tension spring 33 is released by removing the one-way notch mechanism 24 with a fingertip, and the slider 30 main body is slid at a stretch and the set glove is adsorbed on the inner surface of the slider 30 Let) and return to the first operation.
The whole is small and light and easy to handle and easy to use.
Since the support frame side confirmation window 26 and the slider side confirmation window (transparent and closed) 36 are provided, the state of the glove can be seen from the outside and can be assured.

  The lower half of the tip exposed portion of the slider 30 is divided into right and left gull wings. The gull wing 38a with pin and the gull wing 38b without pin swing vertically in the figure and the circumferential length is reduced, so it is easy to set the glove at the tip, and push the gull wing back to its original position with a fingertip Reliable operation is possible while maintaining the sealing performance of the Also, in the one-way notch mechanism 24, the tip of the lever 24a is always pushed up by the spring 24c, and the tip of the notch lever 24a slides on the outer surface of the slider 30 and falls into the recess formed in the slider 30 automatically. It can be fixed. Then, by pulling the lever 24a, the slider 30 slides at a stretch, and the glove is adsorbed on the inner surface of the holder.

  The normal position of the end of the slider 30 is at a position where it is pushed into the support frame 20, and the tension spring 33 at this time remains in a pulled state. The length of the bellows 25 is also short. At this time, a glove is set at the opening end of the slider 30, and by pulling the lever 24a forward so as to remove the one-way notch mechanism 24 from the slider recess 34, the spring force of the slider 30 is reduced at once. By sliding until released and at the same time the bellows 25 also extends, the entire inside of the slider 30 also becomes negative pressure at a stretch, and the glove is dragged and attracted to the inner wall side of the slider 30.

  The negative pressure generated by the bellows 25 passes through the vent 31 and becomes negative throughout. An end on the back side of the bellows 25 is supported by a bellows fixing portion with respect to a wall surface on the back side of the support frame 20.

  The gull wing structure at the tip of the slider 30 is for shortening the circumferential length so that it can be attached as easily as possible when wearing a glove. The left and right lengths are changed so that the gull wings 38a and 38b can be set by one-handed one-touch operation. The gull wings 38a and 38b use spring hinges 38a1 and 38b1 at their mounting portions, and their operation is fixed by the gull wing pin 38d. The obliquely fitted portion of the tips of the gull wings 38a and 38b is sealed with a thin rubber or the like. When the pin 38d comes out of the hole 38d6, the gull wings 38a and 38b spring up in a form of being held by the spring hinges 38a1 and 38b1.

The front end surface of the opening end of the slider 30 and the front end surface of the opening end of the gull wing are both formed into a sheet or an uneven shape having an uneven surface, so that the glove is easily dragged deep when sucked. It is made not to be included.
The performance of the device is influenced by the sealing of the moving parts, such as gull wings, and the connecting parts. The smaller the air suction leak, the longer the glove can be kept expanded (adsorbed). Therefore, it is preferable that all the mating parts have a sealing structure (thin rubber plate or the like).

  In addition, to facilitate application of force when inserting the hand into the expanded glove and pressing it with the slider 30, forming the pushing rod-like projection 39 on the inner surface of the entrance of the slider 30 makes it easy to touch the hand be able to.

  In the present embodiment, the support frame 20 as the outer case is fixed to the base plate 10 as the base, and the slider 30 as the inner case can slide on the outer case.

  In the present embodiment, a bellows 25 is used. However, it is also possible to change the tension springs 33, 33 into the compression spring type 33a, 33a and to accommodate the slider 30 between the inside of the support frame 20 and the slider 30. Furthermore, if the spring stroke travel guide grooves 22 and 22 prevent the inside and the outside of the support frame 20 from communicating with each other, the bellows 25 may not be used. Since the one-way notch mechanism 24 is mounted on the lower side of the lower surface of the support frame 20, the slider 30 and the support frame 20 may always overlap with each other, so that the opening 24e is airtight with the support frame 20 and the slider 30. It does not affect. As described above, the inner case can be airtightly slidable with respect to the inner peripheral surface of the outer case, and the outer case is airtightly formed, so that the bellows is substantially unnecessary as the airtight case. It is possible.

Therefore, by sliding the support frame 20 and the slider 30, a negative pressure is generated inside to expand the glove, and the method by which the glove can be mounted is structurally (Fig. 4) bellows tension spring 33, 33 type (Fig. 4) Fig. 2) There are three methods: compression springs 33a, 33a with bellows and compression springs 33a, 33a without bellows.
10 to 12 show the respective parts of the glove donning apparatus according to the modification in a partially broken state, FIG. 10 is a partially broken top view, and FIG. 11 is a partially broken side view. 12 is a front view.

In each of the drawings, a support frame 120 serving as an outer case is fixed to a pedestal plate 110, and a slider 130 serving as an inner case is supported by the support frame 120. The support frame 120 and the slider 130 both have a substantially oval cross section, the support frame 120 has a cylindrical shape with a bottom, and the slider 130 has a cylindrical shape. A wall surface is formed at the back of the cylinder also in the slider 130, and the slider 130 is in a bottomed state.
The outer shape of the slider 130 and the inner peripheral shape of the support frame 120 can be approached and separated from each other while forming a slight gap therebetween, and can be said to constitute a so-called piston and cylinder.

  Further, as shown in FIG. 13, in order to improve the air tightness, an annular groove 130a is formed on the outer peripheral surface on the back side of the slider 130, and the annular groove 130a has a ring shape. An airtight slide seal 125a is attached. The airtight slide seal 125 a is interposed between the outer peripheral surface of the slider 130 and the inner peripheral surface of the support frame 120 to improve the airtightness. On the other hand, the airtight slide seal 125a is formed of a material having low sliding resistance so that the sliding resistance between the slider 130 and the support frame 120 does not increase.

A support frame side protrusion 127 is formed on the side of the support frame 120, and a groove 137 is formed on the side of the slider 130 in the same manner as the embodiment described above.
A slider opening hole 128 b is formed in the inner wall surface of the slider 130, and the internal space of the slider 130 and the internal space of the support frame 120 communicate with each other. However, for the slider opening hole 128b, the valve with restoring function 129b is mounted on the side of the internal space of the support frame 120, and when the valve with return function 129b is opened, the internal space of the support frame 120 and the slider 130 It communicates with the internal space.

Also, the flow of air is blocked from the inner space of the support frame 20 toward the inner space of the slider 130, and the flow of air is blocked from the inner space of the slider 130 toward the inner space of the support frame 20. It is supposed not to be.
Although the support frame 20 is also a bottomed cylindrical shape which formed the bottom in the cylinder, the outer case open hole 128a is formed in the wall surface of this back side. On the outer surface side of the support frame 120, there is mounted a valve 129a with a restoring function that communicates or shields the inside and the outside through the outer case opening hole 128a. When the restoring function valve 129a is opened, the internal space of the support frame 120 communicates with the outside.

  The valve 129a with a restoring function in this embodiment is opened when the pressure in the support frame 120 becomes positive by pushing the slider 130, and is closed when the pressure is not positive. The outer case open hole 128a and the valve with restoring function 129a correspond to a valve mechanism for maintaining and releasing the positive pressure and the negative pressure in the airtight case. In addition, when the pressure within the support frame 120 becomes positive by pushing the slider 130, the valve 129b with restoration function is airtightly closed, and is not airtight at times other than positive pressure. For example, if it is negative pressure, it will open, and if it becomes almost the same pressure, it will close in a state which can not maintain airtightness. The slider open hole 128 b and the valve with return function 129 b correspond to a valve mechanism for maintaining and releasing positive pressure and negative pressure in the airtight case. When the slider 130 is pushed in, the valve 129b with the restoration function is closed, the valve 129a with the restoration function is opened, and the air in the space formed by the support frame 120 and the slider 130 is pushed out. The valve 129a is closed, the valve with restoring function 129b is opened, and if the glove is attached to the opening of the slider 130, the space inside the support frame 120 and the slider 130 is reduced.

  Here, the support frame 120 corresponds to a bottomed cylindrical outer case, and the slider 130 is slidable with respect to the inner peripheral surface of the outer case, and is formed in a substantially cylindrical shape from the outer case It corresponds to the inner case which can be attached to the opening part of the glove at the protruding part. Further, the support frame 120 and the slider 130 are in airtight communication with the inner space of the inner case, and when the inner case and the outer case are separated in the slidable range, the volume of the inner space is expanded. It corresponds to an airtight case in which the volume of the internal space is reduced when the inner case and the outer case are close to each other. That is, the airtight case is configured without using the bellows 25.

  A compression spring 133 intervenes between a back wall (inner bottom surface) on the inner peripheral surface side of the support frame 20 and a back wall surface (outer bottom surface) on the outer peripheral surface side of the slider 130. A biasing force is generated in the direction of pushing the slider 130 from the side of 120. Although two compression springs 133 are mounted in the drawing, they may be formed of, for example, one elliptical coil spring which is similar to the back wall surface of the slider 130 and slightly smaller. The compression spring 133 corresponds to a biasing mechanism that biases the inner case in the direction in which the inner case is slidable within the slidable range in the outer case.

  A one-way notch mechanism 124 is formed on the lower surface of the support frame 120. The one-way notch mechanism 124 is formed of a lever 124a, a pin 124b, a spring 124c, two plate-like support bracket portions 124d and 124d projecting downward, an opening 124e, etc. The lever 124a is a two plate-like support In a state of being sandwiched between the bracket portions 124d and 124d, it is penetrated by the pin 124b and rotatably supported, and the spring 124c biases the front side of the lever 124a to push downward. As a result, the rear end of the lever 124a enters into the inside of the support frame 120 via the opening 124e and abuts. A slider main body cutout slider recess 134 formed on the lower surface of the slider 130 is formed at the end of the abutment. The slider recess 134 is formed at a predetermined position, and the tip end of the lever 124 a passes over the slider recess 134 when pushing the slider 130, but locks when the slider 30 tries to move in the reverse direction. When the end on the front side of the lever 124a is pulled up against the spring 124c, the lock between the end on the back side of the lever 124a and the slider recess 34 is released, and the biasing force of the compression spring 133 causes the slider 130 to It is a mechanism that is pulled back to the near side.

The above-mentioned gull wing structure is not formed at the open end of the slider 130. Although the circumferential length can not be shortened at the time of wearing the glove, the structure becomes simple and the airtightness of the peripheral wall surface of the slider 130 can be improved.
In the above-described configuration, in the operation of wearing a glove made of rubber, resin or the like, as shown on the upper side of FIG. In this state, the operator pushes the slider 130 into the back of the support frame 120. When the slider 130 is pushed most against the compression spring 133, the tip of the lever 124 a in the one-way notch mechanism 124 is engaged with the slider recess 134. At this time, the open end of the slider 130 protrudes more than the open end of the support frame 120.

  Next, the operator puts the open end of the glove on the open end of the slider 130 while stretching it to the left and right. In this state, both the internal space in the support frame 120 and the internal space of the slider 130 are in the state of normal atmospheric pressure, and the valves 129a and 129b with restoration function are closed. Furthermore, since the open end of the slider 130 is covered with gloves, the internal space in the support frame 120 and the internal space of the slider 130 are airtightly closed spaces.

  Next, when the front side of the lever 124 a of the one-way notch mechanism 124 is pulled up, the tip of the lever 124 a is disengaged from the slider recess 134. Then, the slider 130 is driven in the direction of being pushed out of the support frame 120 by the biasing force of the compression spring 133. Since this movement enlarges the internal space of the support frame 120 and the internal space of the slider 130, negative pressure is generated inside. However, although the restoring function valve 129a is closed to maintain a negative pressure, the restoring function valve 129b is open so that the internal space of the support frame 120 and the internal space of the slider 130 have approximately the same negative pressure. Make it Thereafter, the restoring function valve 129 b functions so that the negative pressure in the internal space of the slider 130 does not flow back to the side of the internal space of the support frame 120. This allows the negative pressure inside the slider 130 to expand the glove for a long time.

  Then, the negative pressure inside the slider 130 mainly causes the glove covered on the open end of the slider 130 to be pushed by the pressure of the outside air and drawn into the inside of the slider 130, and further expands according to the negative pressure. . However, the opening end of the slider 130 is fitted with the anti-slip glove anti-slip 141 so that even if the entire glove is drawn inside the slider 130, it can be prevented from being pulled out from the opening end of the slider 130 .

  In this inflated state, the operator inserts a hand from the open end of the glove. Because the gloves are inflated within the slider 130, the operator can easily insert the gloves up to the fingertips. Even if the gloves are worn on the fingertips, perform the operation to push the hand still. A pushing rod-shaped projection 139 is formed in the inner peripheral side of the slider 130 so as to protrude to the inner peripheral side and spread in the width direction, and the fingertip abuts on the pushing rod-shaped projection 139 in the slider 130. The slider 130 is pushed in at. Since this movement reduces the internal space of the support frame 120 and the internal space of the slider 130, the negative pressure inside the support frame 120 decreases, but on the other hand, the negative space of the internal space of the slider 130 The pressure is maintained. In addition, since the open end of the slider 130 enters the open end of the support frame 120, the support frame side protrusion 127 starts to abut on the end of the rubber glove covered so as to cover the groove 137 and is further pushed. The support frame side projection 127 gradually moves the end of the glove to the open end of the slider 130 and finally removes it from the slider 130.

When the open end rubber glove of the slider 130 is released, the internal space of the slider 130 communicates with the outside air. Also, the slider 130 is sufficiently pushed into the support frame 120, but when the operator starts to pull out the hand, the slider 130 gradually returns to the front side. However, as described above, the lever 124 a of the one-way notch mechanism 124 stops at the position where it is locked to the slider recess 134.
Thereafter, at this position, the opening end of the slider 130 will be resumed from the operation of putting the gloves on again.

As described above, the compression spring 133 is compressed inside the support frame 120 so as to push the slider 130 into a thrust structure. By making the slider open hole 128b larger than the outer case open hole 128a larger, the glove can be easily dragged to the back of the slider 130 by the instantaneously generated negative pressure, and can be expanded. A rubber sheet or the like can be substituted for the valves 129a and 129b with a restoration function. For example, the same function can be exhibited by adhering only in the vicinity of one piece of a square rubber sheet.
In addition, about the valve with a restoration function, it is formed by the one way valve mechanism which opens and closes large.
