Description

TECHNICAL FIELD The present invention relates to a support device for a string-like material delivery and winding device and a string-like material delivery and winding device. More specifically, the present invention provides a support device that can be attached to a delivery and winding device for string-like material to support the delivery and winding device, and a detachable support device that can support the main body of the delivery and winding device. Alternatively, the present invention relates to a delivery and take-up device for cord-like material having an integral support device.

2. Description of the Related Art Conventionally, at construction sites, agricultural work sites, and the like, apparatuses for sending out string-like materials such as plugs, cables, electric wires, and hoses, and winding up the sent string-like materials have been used.
As an example of the feeding/winding device for the above-mentioned cord-like material (hereinafter referred to as "feeding and winding device"), a cord with a power plug is attached to the winding drum of the device that can be connected to the power source. A power supply device that can be wound is mentioned. By using such a power supply device, it is possible to supply electrical energy to a place away from the power source by feeding the cord with a power plug from the power supply device to a desired location. When storing a cord with a power plug, the cord that is sent out is wound on the winding drum, so even if the cord is very long, for example, several tens of meters, the cord can be stored compactly. It becomes possible. Such a power supply device is also generally called an electrical drum or cord reel.

FIG. 10 shows an example of a known take-up take-up device having a general structure. A main body portion of a known delivery winding device 100, for example, a power supply device 100, is mainly composed of a cylindrical winding drum portion 102. As shown in FIG. The cylindrical winding drum portion 102 is freely rotatable about a straight line connecting the centers of both end faces thereof as a central axis.

A base end portion of a string-like material 104 is attached to the device 100, and the string-like material 104 is wound on the side surface, that is, the curved surface of the winding drum portion 102 when stored. String material 104 is a cord with a power plug when device 100 is a power supply device. When the string-like material 104 is fed out from the apparatus 100, the user pulls the leading end of the string-like material 104, and the winding body 102 rotates in response to this force. As a result, the string material 104 wound on the winding drum portion 102 is smoothly sent out from the winding drum portion 102 .

Approximately circular plates 106 are fixedly mounted on both end faces of the winding drum 102 so as to face each other. A rotating handle 108 is attached to one side of the plate-like body 106 . When the user of the delivery winding device 100 operates the rotation handle 108 so as to rotate the plate-like body 106, the winding body 102 is also rotated in conjunction with the rotation of the plate-like body 106. FIG. This allows the user of the device 100 to wind the string-like material 104 onto the curved surface of the winding drum portion 102 .

The delivery take-up device 100 has a grip portion 110 that includes a portion formed in a shape and size that is easy for a user to grip. For example, when winding the string material 104, the user operates the rotary handle 108 with one hand while gripping the grip part 110 with the other hand so that the device 100 does not roll over during winding.

The delivery winding device 100 has a pedestal 112 that supports the device 100, particularly the winding drum 102, so that the winding drum 102 can rotate smoothly without contacting the ground. When the device 100 is placed on the ground such as the ground or the floor, it is placed so that the base 112 is in contact with the flat ground. The grip part 110 and the base 112 often have an integral structure formed by bending a long body such as a metal pipe into an arbitrary shape.

However, the conventional delivery and winding device as shown in FIG. 10 has inconveniences in the delivery and winding operations of the string-like material, as described below.
First, in the case where the user pulls the string-like material to feed out the string-like material from the delivery winding device, the device 100 is simply placed on the ground supported by the base 112 . Since the pedestal 112 is often a simple structure formed by bending a pipe, it cannot be said that the device 100 is stably erected on the ground. Therefore, the device 100 often overturns depending on the degree of tensile force applied to the device 100 . The user must reposition the device 100 each time the device 100 rolls over.

On the other hand, in the case of winding the string-like material on the delivery winding device, the conventional general device delivery winding device 100 has means for appropriately guiding the string-like material 104 onto the curved surface of the winding drum 102 during the winding operation. do not have. As described above, the user who is winding up the string material 104 holds the grip part 110 with one hand (for example, the left hand) and operates the rotating handle 108 with the other hand (for example, the right hand). Therefore, the user himself/herself cannot guide the string material 104 appropriately. Therefore, the string-like material 104 is likely to be wound irregularly on the curved surface of the winding drum 102, in which it is not wound regularly. Not only this, sometimes the string-like material 104, which should be stored on the curved surface of the winding body 102, deviates from the winding body 102 and bites into a member constituting the frame 112, such as a pipe. It may take the user a great deal of time and effort to correct such a situation.

Therefore, it can be easily attached to an existing string-shaped material delivery and winding device, and a support device that enhances the stability and self-support of the device, or a string-shaped material delivery and winding device equipped with such a support device. A device is needed.

In view of such problems, the present invention provides a support device that can be attached to a delivery and winding device for string-like materials, reduces the work burden on the user, and increases the stability and independence of the delivery and winding device during use. It is an object of the present invention to provide a string-like material delivery and take-up device having a simple support device.

In order to solve the above-mentioned problems, the present invention has a mounting member including a mounting element to be mounted on a delivery and take-up device, and a movable member that is movably connected to the mounting member and is movable relative to the mounting member. and the movable member take a folded state or an unfolded state according to the arrangement relationship between the movable member and the movable member. provides a support for a delivery and take-up of cord material that acts as a load bearing for supporting the delivery and take-up to which the support is attached.

Further, in order to solve the above-mentioned problems, the present invention includes a mounting element that is detachably mounted on the delivery take-up device or is integrally coupled with the delivery take-up device, and a mounting member that is movably connected to the installation member. and a movable member that can be displaced relative to the mounting member, can be folded or unfolded according to the positional relationship between the mounting member and the movable member, and the movable member can be arranged relative to the mounting member so as to maintain the unfolded state. A delivery reel for cord material is provided which includes a support device which has a locking element and which, when in a deployed state, acts as a load bearing for at least the movable member to support the delivery reel.

ADVANTAGE OF THE INVENTION According to this invention, the unique effect of improving the stability self-sustainability of the delivery|feeding-up winding apparatus of a string-shaped material in use, and reducing the operation burden of a delivery|feeding-up winding apparatus by a user is produced.

<Embodiment 1>
Next, Embodiment 1 of the supporting device for the feeding and winding device for string-like material according to the present invention will be described in detail with reference to the accompanying drawings. Embodiment 1 of the support device 10 for a delivery take-up device according to the present invention can be mounted on a known delivery take-up device, for example, a delivery take-up device 100 as shown in FIG. The support device 10 attached to the delivery take-up device 100 is placed on the ground (in the following description, the term "ground" means a substantially flat surface regardless of whether it is indoors or outdoors). The device 100 can be stably supported.

The support device 10, as shown in FIG. and a movable connecting element 16 for positive connection. The support device 10 further includes a fixing element that serves to fix the arrangement of the movable member 14 with respect to the mounting member 12 so that a predetermined arrangement relationship obtained by moving the movable member 14 with respect to the mounting member 12 can be maintained. Has 18.

Both the mounting member 12 and the movable member 14 in Embodiment 1 have the shape of a rectangular plate. The plate-shaped bodies constituting these members 12 and 14 may be made of any raw material as long as they have sufficient strength to support the take-up take-up device 100 attached to the support device 10 . Applying a steel plate material having a thickness of about 1.6 mm to these members 12 and 14 is an example of a suitable material to be used. It is more preferable to use materials that are as lightweight as possible for mounting member 12 and movable member 14 . An example of a material particularly suitable for use as the material for these members 12 and 14 is an aluminum plate.

A movable connecting element 16 connected between the mounting member 12 and the movable member 14 is, for example, a hinge, and connects one side edge of the mounting member 12 and one side edge of the movable member 14 so as to bridge both members. is fixed on the edge of the inner plate surface of the
When the mounting member 12 and the movable member 14 are connected by the hinge 16 in this way, the movable member 14 can freely rotate around the rotational axis of the hinge 16 connected to the movable member 14. become. The support device 10 can be in a folded or unfolded state depending on the arrangement of the movable member 14 that moves relative to the mounting member 12 . In addition, the edge portions of the members 12 and 14 facing the edge portions on the side to which the hinge 16 is connected are the same as those of the delivery and take-up device 100 attached to the support device 10 when the support device 10 is in the unfolded state. It becomes a support part that supports the to the ground.

FIG. 2 shows a side view of the support device 10 in its folded state. 3 and 4 also show the support device 10 in the folded state, FIG. 3 being a front view of the support device 10 in the folded state, and FIG. 4 being a rear view at this time.
The fixing element 18 is formed, in this embodiment, by a metal elongated body or wire as a main component. Furthermore, when the fixed element 18 is an elongated body such as a wire as in this embodiment, the wire, which is the fixed element 18, can smoothly pass through the attachment member 12 and the movable member 14, and the diameter of the fixed element 18 can be adjusted. A hole is provided having a diameter approximately equal to .

When a wire is used as the fixing element 18 as in this embodiment, it is excellent in corrosion resistance, rust resistance, abrasion resistance, etc., and has a certain degree of flexibility, for example, a stainless steel wire with a diameter of about 1.0 mm. is preferably used. Of course, the optimum size of the diameter changes depending on the weight of the support device 10 and the attached take-up take-up device 100, the strength of the wire itself, and the like.

Both ends of the elongated fixed element 18 are provided with engaging portions 20 (20a, 20b) having diameters or widths larger than the diameters of the holes drilled in the mounting member 12 and the movable member 14. ing. An elongated fixing element 18 extends from the front of the support device 10 (FIG. 3) through a hole drilled in the mounting member 12 and into the interior of the support device 10 . Then, the elongated fixed element 18 passes through the space sandwiched between the mounting member 12 and the inner plate surface of the movable member 14, that is, the inner region of the support device 10, and furthermore, moves from the inside of the support device 10 to the movable member 14. through a hole drilled in the back of the support device 10 (FIG. 4).

The locking portions 20 are attached to both ends of the fixing element 18 projecting on the outer surface of the support device 10, that is, on the outer plate surface of the mounting member 12 and the movable member 14. As shown in FIG. In the embodiment shown in the accompanying drawings, the locking portion 20 has a substantially cylindrical shape with a larger diameter than the holes drilled in the members 12 and 14. There are no particular restrictions on the shape as long as the dimensions are not large. Moreover, although the same material as that of the fixing element 18 may be used as the raw material of the engaging portion 20, a material different therefrom may also be used.

An elongated fixing element 18 passing through holes drilled in the mounting member 12 and the movable member 14 is free to move within at least one of the holes. One end of the fixing element 18, for example, the locking portion 20a attached to the attachment member 12 side, may be fixedly attached to the attachment member 12. As shown in FIG. In this case, the engaging portion 20a is always in contact with the outer surface of the mounting member 12. As shown in FIG.

By adopting such a configuration, when the support device 10 is expanded to the unfolded state, the angle formed between the mounting member 12 and the inner plate surface of the movable member 14 due to the rotation of the movable member 14 is the same as that of each member 12, 14. It does not widen beyond a predetermined angle determined according to the arrangement position of the hole drilled in and the length of the fixing element 18 . This is because when the outer surface of the movable member 14 rotates until it abuts against the engaging portion 20b, the engaging portion 20b pushes back the contacting plate-like member and prevents further rotation. That is, by providing the locking portions 20 at both ends of the elongated fixed element 18, when the movable member 14 is expanded, the locking portions 20a and 20b of the fixed element 18 are attached to the mounting member 12 and the movable device 14, respectively. abut against the outer surface of the As a result, the arrangement relationship between the mounting member 12 and the movable member 14 in the unfolded state can be fixed at a predetermined angle suitable for supporting the delivery and take-up device 100 mounted on the support device 10 .

Therefore, the arrangement positions of the holes drilled in the respective members 12 and 14 and the length of the fixing element 18 are determined from the stage of designing and manufacturing the support device 10, and are mounted on the support device 10 when the support device 10 is deployed. It is preferable to form an angle suitable for stable support of the delivery take-up device 100 .
Furthermore, it is more preferable that the fixed element 18 has a structure in which the angle formed between the mounting member 12 and the movable member 14 can be arbitrarily adjusted. For example, for at least one of the locking portions 20 provided at both ends of the fixing element 18, it is conceivable to have a structure in which the mounting position on the fixing element 18 can be adjusted to a desired position. By adopting such a structure, the optimum angle can be obtained according to the condition of the ground at the place where the support device 10 to which the delivery winding device 100 is mounted is to be used, and the movable member 14 can be moved at the obtained optimum angle. can be fixed.

The fixing element 18 may have a structure that can be freely attached to and detached from the support device 10 . By adopting such a structure, it is possible to further reduce the storage space required when storing the support device 10 in the folded state.
So far, the present specification has described examples of possible structures when the fixing element 18 is an elongated body (wire). However, any known fixing means capable of fixing the positional relationship between the mounting member 12 and the movable member 14 can be applied as the fixing element 18 without being limited to the above-described one. For example, attaching a hinge or the like to the movable connecting element 16 with a locking element that locks the movable connecting element 16 itself at a predetermined angle when the support device 10 is deployed may fix the positional relationship between the members 12,14. Another way to do this is

On the rear surface of the support device 10, ie, on the outer plate surface of the mounting member 12, a mounting element 22 is provided for fixedly mounting the support device 10 to an arbitrary delivery and take-up device 100. As shown in FIG. As the mounting element 22 of the support device 10, in view of the structure of the delivery and take-up device 100, it is possible to appropriately use a known mounting device.
As described in the section [Background Art], in the conventional delivery and take-up device 100, the holding part 110 and the base 112 are integrated by bending a long body such as a metal pipe into an arbitrary shape. Many of them adopt a structure that is systematically formed. In the case of such a structure, the pipe integrally formed with the gripping portion 110 and the frame 112 and installed in the take-up take-up device 100 is a pipe connecting between the portion forming the gripping portion 110 and the portion forming the frame 112. It would include portion 114 (see FIG. 8).
Therefore, in view of the typical structure of the conventional delivery and take-up device 100, the present embodiment uses the mounting element 22 that can clamp and fix the pipe portion 114 of the delivery and take-up device 100 to the mounting member 12. .

The mounting element 22 in this embodiment includes a clamp 24 that clamps the pipe section 114 of the delivery take-up device 100 to the mounting member 12 . As shown in FIG. 5, the clamp 24 defines a spatial area capable of accommodating the pipe section 114 of the delivery take-up device 100. As shown in FIG. Therefore, the walls of the clamp 24 defining the spatial area are preferably shaped according to the size and shape of the pipe section 114 of a typical delivery and take-up device 100 .

With the pipe portion 114 accommodated in this space area, the clamping body 24 is attached to the mounting member using a connecting element in order to maintain the positional relationship such that the pipe portion 114 is sandwiched between the clamping body 24 and the mounting member 12 . Connect with 12. Attachment of the support device 10 to the delivery take-up device 100 is accomplished by such a connection.

For example, a bolt 26 and a nut 28 can be used as connecting elements for fixing the clamping body 24 to the mounting member 12 . In that case, the attachment member 12 is provided with holes 30 for bolt penetration, and the sandwiching member 24 is provided with holes 32 for bolt penetration. FIG. 6 shows an example of a state in which the supporting device 10 is mounted on the delivery and take-up device 100 using such mounting elements 22. As shown in FIG.

In order to make the attachment of the support device 10 to the delivery take-up device 100 more rigid or to minimize the wear of the components of the support 10, the attachment element 22 can also include components not shown in FIG. , for example, washers. Of course, what can be used as the mounting element 22 is not limited to the mounting device consisting of the clamping body 24, the bolt 26 and the nut 28 used in this embodiment, and another known mounting device can be used as the mounting element 22. I don't mind at all.

The mounting member 12 and the movable member 14 function as a supporting portion for supporting the main body of the supporting device 10 and the delivery take-up device 100 mounted on the supporting device 10 when the supporting device 10 is in the deployed state. As for the support on the mounting member 12 side, instead of or together with the lower end of the mounting member 12, a part of the pedestal 112 of the device 100 may be used as a support.

At least one of the mounting member 12 and the movable member 14, preferably the movable member 14, is provided with an auxiliary support member 34 so that the support device 10 in the unfolded state is less likely to roll over and can be erected more stably on the ground. Keep In this embodiment, the auxiliary support member 34 is provided at the lower end of the movable member 14, which is a rectangular plate-like body, that is, at the edge opposite to the edge of the rectangle to which the movable connecting element 16 is fixed.

In this embodiment, the auxiliary support member 34 is a plate-like body, and its proximal end is connected along the lower end of the movable member 14 . The distal end of the auxiliary support member 34 extends to the inside of the support device 10, that is, to the back side of the movable member 14. As shown in FIG.
The movable member 14 and the auxiliary support 34 can be connected by joining metal plates by welding or the like. 34 may be formed.

By providing such an auxiliary support member 34 to the movable member 14, the movable member 14 acts as a part of the load support section that supports the main body of the support device 10 and the support section 10 and the device 100 attached to the support section 10 in the unfolded state. The contact area will increase. Therefore, the support device 10 in the unfolded state is more difficult to fall down and can be erected on the ground more stably.

Furthermore, it is more preferable to use a material having a high frictional force such as rubber for the auxiliary support member 34 . For example, the auxiliary support member 34 itself may be formed of a high-friction material, or a rubber plate or the like may be provided on the outer surface of the auxiliary support member 34, that is, the surface that contacts the ground when the support device 10 is deployed. By attaching the high-friction plate material, it is possible to make the movable member 14, which functions as a support portion, less likely to slide on the ground when the support device 10 is deployed. FIG. 2 shows a configuration example in which a rubber high-friction plate 36 is attached to the outer surface of the auxiliary support member 34 .

According to a more preferred embodiment, the support device 10 is arranged such that the auxiliary support member 34 is arranged in relation to the movable member 14, e.g. A configuration is adopted in which the mutual connection angle can be freely adjusted. Alternatively, the support device 10 may be configured so that the auxiliary support member 34 can be freely attached to and detached from the movable member 14 .

The dimensions and shapes of the support device 10, particularly the mounting member 12 and the movable member 14, are preferably determined in consideration of the mounting of the delivery and take-up device 100 as shown in FIG. For example, the height or longitudinal length of the movable member 14 is preferably sized such that the lower end of the movable member 14 does not hit the ground even in the folded state. Moreover, the dimensions and shapes of the mounting member 12 and the mounting element 22 are preferably determined according to the dimensions and shape of the take-up take-up device 100 that is supposed to be mounted. Since the size and shape of the take-up take-up device 100 differ slightly depending on the model, the size and shape of the attachment member 12 and the take-up device 22 are designed so that they can be attached to as many models of take-up take-up device 100 as possible. It is preferable that the supporting device 10 is configured in such a manner as to increase the versatility of the supporting device 10 .

From now on, an example of how to use the support device 10 when the embodiment of the support device 10 according to the present invention is mounted on the delivery take-up device 100 will be described. When using the take-up take-up device 100 with the supporting device 10 attached, the user of the supporting part 10 moves the movable member 14 of the supporting part 10 in the folded state (see FIG. 6) to the locking part 20b of the fixing element 18. is rotated with respect to the mounting member 12 until it contacts and cannot move further. As a result of such an operation by the user, the support device 10 is in the deployed state.

Next, the user erects the support device 10 in the unfolded state against the ground. The standing arrangement is utilized such that at least one of the lower end of the movable member 14 and the lower end of the mounting member 12 and a portion of the cradle 112 serve as load bearing portions for the support device 10 and the delivery take-up device 100 attached thereto. This is accomplished by the person placing the support device 10 with the delivery take-up device 100 on the ground. At this time, the delivery winding device 100 supported by the support device 10 in the unfolded state is placed obliquely with respect to the ground as shown in FIG.

When the string-like material 104 wound on the winding body 102, for example, a cord with a power plug for an electrical drum, is to be sent out from the take-up winding device 100, the user pulls the leading end of the string-like material 104. While holding it, move it to the desired location. As a result, the string-like material 104 is pulled out from the delivery reeling device 100, and the delivery reeling device 100, which receives the tensile force to the string-like material 104, randomly receives forces of various magnitudes from various directions. become. However, the sub-elements of the support device 10 acting as load bearing members, in particular the auxiliary supports 34 of the movable member 14, prevent the support device 10, which supports the delivery retractor 100 while being mounted in an inclined state, from sliding or overturning. can be prevented. Therefore, by using the delivery take-up device 100 and the attached support device 10, the take-up take-up device 100 can more stably stand on its own while delivering the string material 104 on the ground.

When winding and recovering the string material 104 delivered from the winding body 102 of the delivery take-up device 100, the user rotates the rotary handle 108 of the delivery take-up device 100 tilted by the support 10. Rotate with one hand and guide the string material 104 with the other hand so that the string material 104 to be wound is properly wound onto the winding body 102 . Unlike the conventional winding work, the user who is operating the handle 108 to wind the string-like material 104 holds the grip part 110 with one hand in order to prevent the delivery winding device 100 from overturning. No need to grab. Therefore, the user of the delivery winding device 100 equipped with the supporting device 10 can wind and collect the string-like material 104 onto the winding body 104 of the device 100 more smoothly and in an orderly manner.

So far, the first embodiment of the support device 10 according to the present invention has been described. The support device 10 described so far is used by being attached to an arbitrary delivery and take-up device 100 as required. However, the support device 10 may adopt a structure that is detachable from a specific take-up take-up device 100 on the assumption that it is used as a dedicated product for a take-out take-up device 100, or may be a take-up take-up device from the beginning. A structure integrally coupled with the picking device 100 may be adopted. For example, the business may manufacture and sell the detachable or integral delivery take-up device 100 with the supporting device 10 as a product. If the delivery take-up device 100 includes an embodiment of the supporting device 10 according to the present invention, the commercial implementation of the device 100 naturally corresponds to the commercial implementation of the supporting device 10 according to the present invention. It will happen.

<Embodiment 2>
Next, Embodiment 2 of the invention of the present application will be described with reference to the drawings. In the second embodiment, description of the same points as in the first embodiment will be omitted as appropriate, and the description will focus on the points that differ from the first embodiment.

As shown in FIG. 8, the movable connecting element 16 connected between the mounting member 12 and the movable member 14 includes a hollow pipe member 161 installed at the upper end of the mounting member 12 and a hollow pipe member 161 installed at the upper end of the movable member 14. The arm member 162 is fitted and formed so that it can freely rotate. The pipe member 161 has a substantially cylindrical shape, and a pair of arm members 162R and 162L are inserted into its hollow portion. The pipe member 161 is installed at the upper end of the inner plate surface of the mounting member 12, but may be installed at the upper end of the outer plate surface of the mounting member 12 or the upper end of the side surface. The pipe member 161 is installed horizontally on the ground, and the installation method can employ a known method such as welding that can be fixed. Although the pipe member 161 is singular in Embodiment 2, it may be plural.

As shown in FIG. 8, a pair of arm members 162R and 162L are installed at the upper end of the movable member . The arm member 162 has a substantially cylindrical shape, one end (hereinafter referred to as a tip end) is inserted into the hollow portion of the pipe member 161, and the base end is connected to the movable member . The outer diameter of arm member 162 is slightly smaller than the inner diameter of pipe member 161, and pipe member 161 and arm member 162 are fitted together so as to be freely rotatable. Fitting refers to a loose, sliding fit. The shape of the arm member 162 is not limited to a substantially cylindrical shape, and any shape that can be freely rotated, such as a cylindrical shape, a polygonal column, or a columnar shape with a cross-shaped cross section, can be employed.

As shown in FIG. 8, base ends of the pair of arm members 162R and 162L are connected to a pair of side bars 141R and 141L extending downward, respectively. Lower ends of the pair of side bars 141R and 141L are connected to ends of the bottom bar 142, respectively. A substantially U-shaped member formed by a pair of side bars 141R and 141L and a bottom bar 142 (represented by broken lines in FIG. 8) constitutes the movable member 14 of the second embodiment. The arm member, the side bar 141 and the bottom bar 142 may be formed by bending a single long body such as a solid bar or pipe to form an integral structure.

The lower ends of the pair of side bars 141R, 141L are connected to the pair of bottom side bars 341R, 341L extending toward the mounting member 12, and the other ends of the pair of bottom side bars 341R, 341L are connected to the bottom bar 342. can be configured as A pair of bottom side bars 341R, 341L and a bottom bar 342 constitute a substantially U-shaped auxiliary support member 34 of the second embodiment. When adopting such a configuration, the bottom bar 142 can be omitted. The auxiliary support member 34 may be formed into an arch shape by bending a single elongated body, or may adopt various shapes as long as the shape protrudes toward the mounting member 12 direction. can.

As shown in FIGS. 8 and 9, the pair of arm members 162R and 162L are positioned in the vicinity of the proximal end portions of the pair of arm members 162R and 162L and at positions where the arm members 162R and 162L do not enter the pipe member 161. A pair of locking protrusions 181R and 181L are provided on the side surface and extend radially with respect to the pivot shaft. The locking projections 181R and 181L are thin plate-shaped, and are sized to rotate with the rotation of the arm members 162R and 162L and come into contact with the upper end of the mounting member 12. As shown in FIG. The locking protrusions 181R and 181L constitute the fixing element 18 of the second embodiment.

By adopting such a configuration, when the support device 10 is expanded to the unfolded state, the angle formed between the mounting member 12 and the movable member 14 due to the rotation of the movable member 14 is equal to the installation position of the locking protrusion 181. It does not spread beyond a predetermined angle determined by . When the pair of locking protrusions 181R and 181L rotates until they contact the upper end of the mounting member 12, the upper end of the mounting member 12 pushes back the pair of locking protrusions 181R and 181L. This is because the rotation of the is suppressed. By adopting the configuration as in Embodiment 2, it is possible to reduce the weight, reduce the number of members used, and make it possible to manufacture at low cost.

Thus, in the present invention, various modifications and replacements are possible without departing from the scope and gist of the attached claims, or the essential configuration can be configured equivalently to the above-described embodiments. is clear to those skilled in the art.
