Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a light-emitting umbrella that emits light from a pillar, a ram, etc. of the umbrella.

[0002]

[Prior art]

 In general umbrellas, a lower wheel that pivotally supports the base of the receiving bone with a holding needle or the like is slidably fitted to a column, and the lower wheel is placed in an umbrella closed position and an open umbrella position, respectively. In order to lock, a locking member commonly called “hajiki” is provided corresponding to the locking position of the lower wheel on the column in each of the closed state and the opened state.

The cissing is generally made of a metal plate that is long in the axial direction of the column (about 5 to 6 cm), and the cissing is carried out by inserting the plate surface into the radial direction of the column in the axially long receiving groove formed in the column. And is retractably housed in a state of being biased by a spring in a direction protruding from the surface of the column, and when the umbrella is closed, a cissing provided at a position close to the grip is formed on the lower wheel. The lower wheel is locked in the closed position by engaging in the long groove in the axial direction, and at the time of opening, the cissing on the tip side of the support comes into contact with the lower end surface of the lower wheel and the lower wheel is in the open position. The locking is performed, and the repelling of the lower wheel to the column is released by pushing the repelling member with a finger and immersing it in the receiving groove.

On the other hand, for example, Japanese Patent Application Laid-Open No. 9-322813 discloses that a column of an umbrella is formed of a translucent member such as an acrylic resin, a light source such as a miniature bulb or an LED, and a battery as a power supply. There is disclosed a light emitting umbrella in which an on / off switch is provided on a handle, and light from a light source is incident on the translucent support to emit light from the support and the ram.

According to such a configuration of the light emitting umbrella, compared to a case in which a miniature bulb is provided in a stone butt and a battery is provided in a handle, not only the stone butt but also a support can be made to emit light. Since the area is large and wide, and the light source is hard to be seen directly, there is an advantage that the light emitting portion can emit light with soft light. In addition, there is no problem that the miniature bulb is easily damaged, and since there is no need to wire the lead wires inside the pillar, there is an advantage that neither component cost nor production cost is required.

[0006]

[Problems to be solved by the invention]

 However, in a light-emitting umbrella in which the support is formed of a translucent member such as an acrylic resin as described in the above-mentioned publication, it is not desirable to provide a conventional type of repelling on the support for the following two reasons.

The first reason is that a relatively deep and long groove in the axial direction of the column is provided in the column for accommodating the cissing so as to be able to come and go, so that a metal like conventional umbrella can be used. This means that the strength of a column made of an acrylic resin or the like having no strength is reduced, and a predetermined strength cannot be maintained.

[0008] The second reason is that the presence of cissing in the column hinders the transmission of light in the column and lowers the luminous brightness of the stone pillar.

In view of the above circumstances, the present invention provides a light-emitting umbrella having a light source in a grip to allow light to enter the column, thereby ensuring the strength of the column and improving light transmission within the column. It is an object of the present invention to provide a light emitting umbrella provided with a lower wheel locking structure.

[0010]

[Means for Solving the Problems]

 In the luminous umbrella according to the present invention, no cissing is provided in the support, and small holes are formed on the surface of the support corresponding to the positions of the lower wheels on the support in the closed state and the open state, respectively. An operating member having a locking projection capable of engaging with the lower end is movable between a locking position where the projection is engaged with the small hole and an unlocking position where the projection is released from the small hole. It is characterized by being provided on a potter's wheel.

[0011] The translucent support can be formed of a synthetic resin material.

It is preferable that the operation member is pivotally supported by the lower wheel, and it is more preferable that the operation member is spring-biased toward the engagement position.

It is preferable that the support has a polygonal cross-sectional shape such as an octagon.

[0014] Further, a lid member for covering the battery accommodating chamber provided in the grip is screwed onto the grip, and a light source is turned on with the rotation of the lid member in the first direction. It is preferable that the light source be turned off as the member rotates in a second direction opposite to the first direction. In this case, the first rotation direction of the lid member is preferably the same direction as the direction in which the lid member is screwed into the grip, that is, clockwise as viewed from the operator side.

[0015]

[Effect of the invention]

 In the luminous umbrella according to the present invention, the operation member capable of releasing the locking of the lower wheel with respect to the column is provided on the lower wheel side, so that the lower column locks the column in the closed state and the opened state. It is only necessary to form relatively shallow small holes at two locations corresponding to the positions. Therefore, even when the entire support is made of a translucent material such as an acrylic resin having no strength such as a metal, the predetermined support strength can be maintained and light transmission in the support is prevented. Less often.

When the operating member is pivotally supported on the lower wheel side in a state of being biased by a spring toward the locking position, the operability is good as in the case of the conventional repelling.

Further, by forming the cross-sectional shape perpendicular to the axis of the support column into a polygon such as an octagon, for example, the light diffusibility is improved and the appearance is improved.

Further, if a lid member is screwed on the grip so as to cover the battery accommodating chamber provided in the grip, and the lid is turned, the light source can be turned on and off. There is no need to separately provide an open / close switch for the electric circuit, and the operability is good.

[0019]

[Embodiment of the invention]

 Hereinafter, an embodiment of a light emitting umbrella according to the present invention will be described in detail with reference to the drawings.

FIG. 1 is a cross-sectional view of a main part of a light-emitting umbrella according to an embodiment of the present invention, in which a support column and a lower wheel slidably fitted to the support column are partially omitted. And the lower wheel is locked in the closed position. FIG. 2 is a cross-sectional view of a main part showing a state where the operating member is operated at the time of opening the umbrella and the locked state of the lower wheel is released.

In FIG. 1, a column 1 of the light-emitting umbrella is entirely formed of a translucent material whose cross section perpendicular to its axis forms an octagon, for example, an acrylic resin, and has a translucent synthetic resin material at the upper end. Stone foot 1a. The support 1 has a relatively small first small hole 3A formed at a position near the base 1b of the support 1 corresponding to the position where the lower wheel 2 is locked on the support 1 in the closed state. A similar small hole 3B is formed at a position on the distal end side of the column 1 corresponding to the locking position of the lower wheel 2 on the column 1 in the opened state.

The lower part 2 provided with a receiving bone pivoting flange 2a (a receiving bone, a holding needle, a groove and the like are omitted) at an upper end is provided with a seesaw type operation member 4 so as to be pivotable. I have. The operating member 4 is pivotally supported by a lower wheel 2 near the center by a pin 5 extending in a direction perpendicular to the paper surface of FIG. 1, and arm portions 4 a extending vertically with the pin 5 as a center. 4b. On the arm portion 4a below the pin 5, a locking projection 4c which can be engaged with the small holes 3A, 3B is provided to penetrate the lower wheel 2 and protrude toward the column 1.

The arm 4 b on the upper side of the pin 5 of the operation member 4 forms an operation part protruding from the outer peripheral surface of the lower wheel 2, and is provided between the arm 4 b and the lower wheel 2. As the coil spring 6 is contracted, the operating member 4 is biased clockwise in the figure around the pin 5.

Therefore, when the lower wheel 2 slid along the column 1 reaches a position where the locking projection 4c matches the small hole 3A or 3B of the column 2, the locking projection 4c is coiled. The urging force of the spring 6 engages in the small hole 3A or 3B, and the lower wheel 2 is locked at the closed position or the opened position, respectively. Then, in the locked state of the lower wheel 2, the upper arm 4b of the operation member 4 is pressed with a finger against the urging force of the coil spring 6, and the operation member 4 is pressed as shown in FIG. By rotating counterclockwise in the figure, the locking projection 4c escapes from the small hole 3A or 3B of the column 2, and the locked state of the lower wheel 2 is released, and the umbrella can be opened or closed. become.

On the other hand, a cylindrical grip 10 having a configuration as shown in FIG. 3 is attached to the base 1 b of the column 1. The grip 10 includes a fixing portion 11 fitted and fixed to a root portion 1b of the column 1, a light source / battery storage portion 12 detachably screwed to a lower end of the fixing portion 11, and a light source / battery. It is composed of three parts: a cup-shaped lid member 13 which is detachably screwed to the lower end of the housing 12.

The fixing part 11 includes an outer cylinder 11 a made of a translucent synthetic resin material. The outer cylinder 11 a is formed such that a lower end face 1 c perpendicular to the axis of the column 1 can be a light incident surface. The lower part is open, and when the upper end of the light source / battery accommodating portion 12 is screwed onto the inner peripheral surface of the outer cylinder 11, the upper end of the light source / battery accommodating portion 12 is provided together with the reflecting mirror 14. A miniature bulb (light source) 15 is inserted into the space of the open portion of the outer cylinder 11 a, whereby the miniature bulb 15 is configured to face the lower end surface 1 c of the base of the support 1.

The inside of the light source / battery accommodating section 12 serves as a battery accommodating chamber 17 for accommodating two AA batteries 16A and 16B in a state where their positive electrodes are directed upward and connected in series. The positive electrode 16a of the upper battery 16A is electrically connected to one electrode (center electrode) of the miniature lamp 15 via an appropriate conductive contact piece 18. The other electrode of the miniature bulb 15 is electrically connected to a conductive connecting piece 19 extending to the lower end of the light source / battery housing section 12 along the inner wall of the battery housing chamber 17. Such a conductive structure is known per se, and further detailed description and illustration are omitted.

FIG. 4 is an enlarged cross-sectional view showing the lower end of the light source / battery accommodating portion 12 and the lid member 13 screwed to cover the lower portion of the battery accommodating chamber 17.

A conductive ring 20 is fixed to a lower end portion of the light source / battery accommodating portion 12 so as to cover the cylindrical lower edge portion 12a, and the conductive ring 20 is connected to the conductive connecting piece 19. The conductive ring 20 is electrically connected to the other electrode of the miniature lamp 15 by being electrically connected to the other electrode.

A conductive coil spring 21 is attached to the upper surface of the bottom plate 13 a of the cover member 13, and the upper end of the coil spring 21 electrically contacts the negative electrode 16 b of the battery 16 B on the lower side. At the same time, the lid member 13 is rotated clockwise as viewed from the lower side in FIG. 4 and screwed into the light source / battery accommodating portion 12 to push up the batteries 16B and 16A, thereby to lift the upper battery 16A. The positive electrode 16 a is brought into contact with the conductive contact piece 18, thereby having a function of conducting the positive electrode 16 a of the battery 16 A on the upper side to one electrode of the miniature lamp 15.

Until the lid member 13 is completely screwed into the light source / battery accommodating portion 12, the coil spring 21 does not touch the conductive ring 20 as shown in FIG. Therefore, the miniature bulb 15 is in a light-off state. In this state, when the cover member 13 is rotated clockwise (first direction) as viewed from below in FIG. 4 and completely screwed into the light source / battery accommodating section 12, the cover 13 shown in FIG. As shown in (b), when the coil spring 21 contacts the conductive ring 20, the negative electrode 16b of the battery 16B on the lower side passes through the coil spring 21-conductive ring 20-connection piece 19 and the miniature bulb. The other bulb 15 is electrically connected, and the miniature bulb 15 is turned on.

When the miniature bulb 15 is turned on, the portion around the miniature bulb 15 of the fixing portion 11 of the grip 10 emits light, and light is incident on the column 1 from the lower end face 1 c of the base of the column 1, and the column 1 At the same time, the light transmitted through the support 1 causes the stone 1a at the upper end of the support to emit light.

When the cover member 13 is rotated counterclockwise (second direction) when viewed from below in FIG. 4 in the lighting state of the miniature bulb 15, the coil spring 21 is moved from the conductive ring 20. Then, the miniature bulb 15 is turned off after returning to the state shown in FIG.

As is apparent from the above description, according to the present embodiment, the operation member 4 that can release the locking of the lower wheel 2 to the column 1 is provided on the lower wheel 2 side. Only two relatively shallow small holes 3A and 3B need to be formed in the column 1. Therefore, even when the entire support 1 is made of a translucent material such as an acrylic resin having no strength such as a metal, the predetermined support strength can be maintained, and the light transmission within the support 1 can be improved. It has the advantage of improving.

Further, since the operating member 4 is pivotally supported by the lower wheel 2 in a state where the operating member 4 is biased toward the locking position by the coil spring 6, the upper arm portion of the operating member 4 is provided. Since the locked state of the lower wheel 2 can be released only by pressing the 4b with the finger against the urging force of the coil spring 6, the operability is good.

Furthermore, since the cross-sectional shape perpendicular to the axis of the column 1 is formed in a polygon such as an octagon, light is diffused and an aesthetic appearance is obtained.

Furthermore, the turning on and off of the miniature bulb 15 can be performed by turning the lid member 13 screwed into the light source / battery housing section 12 so as to cover the battery housing chamber 17 provided in the grip 10. Therefore, it is not necessary to separately provide an open / close switch for the electric circuit, and various effects such as good operability can be obtained.
