DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a foldable umbrella stand.

[0002]

2. Description of the Related Art As an umbrella stand of this type, there is an umbrella stand that is box-shaped when in use, and can be folded and stored small when not in use or can be leaned against. Such a foldable umbrella stand has upper, middle, and lower frame bodies for holding the umbrella, struts for rotatably supporting the respective frame bodies, and predetermined struts when the respective frame bodies are used. And a lock mechanism for fixing the position. The lock mechanism is configured to release the fixation of the respective frame bodies to the support columns by operating the operation section provided on the middle frame body. When not in use, the umbrella stand is folded and the umbrella stand is folded small by operating the operation unit and rotating each frame body with respect to the column.

[0003]

However, in the structure described above, the operation section provided on the inner frame body is
For example, it may be operated even when a hand is moved when moving to the installation place, and the lock mechanism may be unintentionally released. In other words, the structure is such that the lock mechanism can be released even if the release mechanism is completely unaware. For this reason, when unintentionally putting a hand on the operation section, each frame starts to rotate, and the other hand is caught between the frame and the column or between the frames, possibly injuring. There were things.

An object of the present invention is to solve such a problem.

[0005]

In order to achieve the above object, the present invention takes the following measures. That is, the umbrella stand according to the present invention includes an upper frame body that can support the vicinity of the upper end of the housed umbrella, a lower frame body that can support the vicinity of the lower end of the umbrella, and a position where they substantially overlap each other when not in use. A pillar that connects the upper frame body and the lower frame body so as to be relatively rotatable, and supports the upper frame body and the lower frame body at a predetermined position during use, and an upper frame body during use. A lock mechanism for prohibiting rotation of the lower frame and the column with respect to the column; a release mechanism for releasing the operation of the lock mechanism; and a release inhibiting mechanism for inhibiting the operation of the release mechanism.
The upper frame and the lower frame with a space having a predetermined width.
It is characterized in that it is supported by a support via a support .

With the above construction, it is possible to prevent fingers from being caught between the support and the upper and lower frames when the upper and lower frames are rotated with respect to the support.

As a desirable mode of the release inhibiting mechanism, a leaf spring for inhibiting the operation of the release mechanism and urging the release mechanism in a direction for maintaining the state, and a release mechanism for deactivating the urging force of the leaf spring are provided. Mention may be made of an enabling button.

[0008]

With such a structure, in order to release the lock mechanism, the release prohibition mechanism that activates the operation of the release mechanism is operated to put the lock mechanism in the releasable state, and thereafter, It requires a two-step operation of activating the release mechanism to release the operation of the lock mechanism. Therefore, the release mechanism cannot be operated unless the lock mechanism is operated with the consciousness of releasing. therefore,
Even if the operator accidentally puts his / her hand on the release mechanism, the upper and lower frames and the column are not relatively rotated so as to be in a non-use state. Therefore, when you try to fold the umbrella stand by releasing the lock mechanism, that is, when you change the state from the used state to the unused state, always hold your finger in a safe place so as to avoid the part where there is a risk of jamming your finger. It can be taken into consideration, and problems such as stuffing fingers when folding can be solved.

Further, interposed a post, a spacer having a predetermined width between the upper frame and the lower frame is supported by the posts
Therefore , even if the upper frame and the lower frame are rotated with respect to the support so that they are substantially overlapped with each other, the width of the spacer is always kept between the support and the upper and lower frames. Since a corresponding gap is generated, the upper frame body and the lower frame body will not come into contact with the support columns. Therefore, by setting the width of this spacer to be at least the thickness of an adult's finger, it is possible to more reliably prevent the situation in which the support column, the upper frame body, and the lower frame body are packed with fingers.

[0010]

An embodiment of the present invention will be described below with reference to the drawings.

The umbrella stand 1 shown in FIGS. 1 to 6 has a box shape as shown in FIG. 1 when it is used and can be folded into a substantially flat shape as shown in FIG. 6 when it is not used. The umbrella stand 1 includes an upper frame body 2 capable of supporting the vicinity of the upper end of the housed umbrella and a lower frame body 3 capable of supporting the vicinity of the lower end of the umbrella.
The upper frame 21 and the lower frame 3 are supported via a spacer 4 having a predetermined width, and when not in use, the upper frame 21 and the lower frame can be relatively rotated to a position where they are substantially overlapped with each other. Reinforce the four pillars 5 that connect the body 3 and support the upper frame body 2 and the lower frame body 3 at predetermined positions when in use, and the left and right pillars 5 at substantially the central portion in the vertical direction. And a lock mechanism 7 for prohibiting rotation of the upper frame 2 and the lower frame 3 with respect to the column 5 during use.
And a release mechanism 8 for releasing the operation of the lock mechanism 7.
And a release inhibition mechanism 9 for inhibiting the operation of the release mechanism 8.

The upper frame 2 is formed by arranging grid-like partition bars 24 on a rectangular frame in which the left and right side frames 21 and the front and rear frames 22 are connected to each other through joints 23. Spacer 4 on the side of joint 23
Is stuck. The upper frame 2 is rotatably attached to the support 5 via the spacer 4 so as to be substantially flush with the upper end of the support 5. A housing member 10 housing the lock mechanism 7, the release mechanism 8 and the release prohibition mechanism 9 is attached to the lower surface of the rear frame 22 of the upper frame body 2. The housing member 10 is shown in FIG.
As shown in FIG. 2, a box body 11 having a rectangular vertical cross section for accommodating the operating rod 14 therein, a vertical portion 12 formed by extending one vertical side of the vertical cross section of the box body 1, and a vertical portion thereof. The horizontal end 13 is formed integrally by bending the extending end of 12 to the other side of the vertical section, and the length in the longitudinal direction is the opposing surface of the left and right opposing columns 5. It has a length slightly shorter than the distance between them. The width of the spacer 4 is set to, for example, 1.5 cm, which is greater than the thickness of an adult finger. 25
Is a member for improving sliding when the upper frame body 2 is rotated with respect to the support column 5.

The lower frame body 3 has umbrella water in substantially the same frame as the upper frame body 2 which has a rectangular shape in a plan view in which the left and right side frames 31 and the front and rear frames 32 are connected to each other through joints 33. A dish-shaped water receiver 34 for receiving is erected, and a spacer 4 is fixed to the side surface of each joint 33. The lower frame 3 is attached via the spacer 4 so as to be rotatable upward from the lower end of the column 5 by a predetermined distance.

The column 5 has a prismatic shape, and supports the upper frame 2 and the lower frame 3 with four spacers 4 therebetween. A lock mechanism 7 is arranged on the rear column 5. That is, a hole 71 into which a lock pin 72 of a lock mechanism 7, which will be described later, can be loosely fitted and engaged is formed at a predetermined position on the opposing side surface of the rear pillar 5, and the lock pin 72 is provided around the hole 71. A guide member 73 having a guide surface 73a for guiding 72 to the hole 71 is attached. Caps 51 are fitted to the upper and lower ends of the support column 5, and non-slip rubber 52 is provided below the lower end cap 51.

Next, the lock mechanism 7, the release mechanism 8 and the release prohibition mechanism 9 will be described, but for convenience of description, they are shown in the direction viewed from the rear side as shown in FIGS. That is, the right in the front view is expressed as the left in the rear view, and the front in the front view is expressed as the rear in the rear view.

As shown in FIG. 5, the lock mechanism 7 engages with a hole 71 formed in a predetermined position on the inner side surfaces of the left and right columns 5 located at the front and loosely fitted into the hole 71 when in use. A lock pin 72 to be obtained, and a guide member 73 for guiding the lock pin 72 to the hole 71 when changing from a non-use state to a use state.
Consists of As shown in FIG. 5, the lock pin 72 is, for example, the lock pin 72 located on the left side, which is provided by protruding leftward on the left end of the operating rod 14 which will be described later.
Is always urged to the left, that is, toward the column 5. That is, the lock pin 72 is urged in a direction in which the lock pin 72 engages with the hole 71 at a predetermined depth and is not always released from the engagement with the hole 71 when used. By the engagement of the lock pin 72 and the hole 71, the upper frame body 2 and the lower frame body 3 are held perpendicular to the support column 5.

The release mechanism 8 is, as shown in FIG.
A guide pin 81 which is provided on the facing surfaces of the left and right actuating rods 17 which are opposed to each other and which is accommodated in the first unit, and which moves the actuating rods 17 left and right, and a guide which slides up and down to the cam surface 82. It comprises a lever 83 having left and right cam surfaces 82 for guiding the pin 81 in the left-right direction. Specifically, for example, the guide pin 81 fixedly provided on the left actuating rod 17 is always biased by the spring 15 in the direction in which the guide pin 81 is in sliding contact with the cam surface 82, that is, to the left. The guide pin 81 is in sliding contact with the right-side cam surface 82 that extends downward to the right while being biased to the left. The right cam surface 82 moves upward to move the guide pin 81 to the right. The moving distance of the guide pin 81 to the right is set to a value larger than the depth of engagement between the lock pin 72 and the hole 71. Therefore, when the guide pin 81 connected to the lock pin 72 via the operating rod 17 moves to the right, the lock pin 72 also moves to the right, and the lock pin 72 and the hole 71 are engaged with each other. Can be released.

As for the lock mechanism 7 and the release mechanism 8, only those arranged on the left side have been described above, but the right side structure has the same structure.
Description is omitted.

The release inhibiting mechanism 9 inhibits the operation of the release mechanism 8 and urges the release mechanism 8 in a direction to hold the state, and the release mechanism by deactivating the urging force of the plate spring 91. And a button 92 enabling 8 For more information,
The leaf spring 91 has one end fixed to the vertical portion 12 of the housing member 10 and the other end fixed to a button 92 that is biased toward the vertical portion 12 and is held by the vertical portion 12 so as to be movable back and forth. That is, the leaf spring 91, which is cantilevered by the vertical portion 12, is prohibited from moving in the vertical direction,
In the used state, the upper end of the lever 83 is locked so as to prohibit the lever 83 of the release mechanism 8 from moving upward. The button 92 includes a shaft 93 that penetrates from the front surface to the rear surface of the vertical portion 12 in the front-rear direction and a pressing portion 94 formed at one end of the shaft 93 and having a larger diameter than the shaft 93. A leaf spring 91 is fixed to the other end of the shaft 93. The pressing portion 94 is formed by exposing the entire front surface of the housing member 10.
By pushing backward, the leaf spring 91 fixed to the other end of the shaft 93 can be moved backward.

In the umbrella stand 1 having such a structure, as shown in FIG.
In order to change the box shape when used as shown in Fig. 6 to the folded state when not used as shown in Fig. 6, the following procedure may be performed. At that time, the lock mechanism 7, the release mechanism 8 and The release inhibition mechanism 9 is shown in FIGS. FIG. 7 shows the lock mechanism 7, the release mechanism 8, and the release prohibition mechanism 9 during use. The lock pin 72 of the lock mechanism 7 is the hole 71 of the column 5.
The lever 83 of the release mechanism 8 is prohibited from moving upward by the leaf spring 91 of the release prohibition mechanism 9. That is, the release mechanism 8 is prohibited from operating by the leaf spring 91. As shown in FIG. 8, the release prohibition mechanism 9
When the button 92 is pressed, the inhibition of the operation of the release mechanism 8 by the leaf spring 91 of the release inhibition mechanism 9 is released. Therefore, although the release mechanism 8 can be operated, the lock pin 72 of the lock mechanism 7 is still engaged with the hole 71 of the column 5. In this state, as shown in FIG. 9, the release mechanism 8
The lever 83 of is lifted upward. Since the cam surface 82 moves upward similarly to the lever 83, the guide pin 81 moves rightward along the cam surface 82. The lock pin 72 connected to the guide pin 81 via the operating rod 14 also moves to the right, and the engagement between the lock pin 72 and the hole 71 is released. Therefore, since the lock mechanism 7 that has locked the holding of the upper frame member 2 and the lower frame member 3 in the use state by the support column 5 is released, the upper frame member 2 is rotated with respect to the support column 5 in this state. By doing so, the umbrella stand 1 can be folded.

In order to change the folded state when not in use to the used state, the upper frame member 2 may be lifted while rotating with respect to the support column 5. At this time, the lock pin 72 is guided by the guide member 73. And is engaged with the hole 71. That is, the upper frame member 2 and the lower frame member 3 are locked and supported by the support column 5.

With such a structure, in order to release the lock mechanism 7 at the time of use, the release prohibition mechanism 9 that enables the lock mechanism 7 to be released is actuated, that is, the button 92 is pressed. It is necessary to lift the lever 82 in the pressed state to release the engagement of the lock pin 72 with the hole 71 to release the lock mechanism 7, and the lock mechanism 7 is released unless the two-step operation is performed at the same time. Never. Therefore, the lock mechanism 7 is not accidentally released, and the lock mechanism 7 can be released only when the lock mechanism 7 is intended to be released. Therefore,
When the lock mechanism 7 is released and the umbrella stand 1 is to be folded, that is, when the umbrella stand 1 is changed from the used state to the non-used state,
Care can be taken to always hold your finger in a safe place to avoid areas that could be stuffed. Therefore, it is possible to eliminate problems such as stuffing fingers when folding.

Further, a predetermined width, that is, 1.5, between the column 5 and the upper frame 2 and the lower frame 3 supported by the column 5.
Since the spacer 4 having a width of cm is provided, even if the upper frame 2 and the lower frame 3 are rotated with respect to the support 5 so as to be substantially overlapped with each other, the support 5 and the upper frame 3 2 and the lower frame 3 are always the width of the spacer 4, that is, 1.5.
Since there is a gap of cm, the upper frame body 2 and the lower frame body 3 do not come into contact with the support column 5, and it is sure that the support column 5 and the upper frame body 2 and the lower frame body 3 are packed with fingers. Can be prevented.

The present invention is not limited to the above-described embodiments, and for example, the upper frame 2 and the lower frame 3 may have a circular shape in a plan view. Various modifications are possible without departing from the range.

[0025]

As described above in detail, according to the present invention, in order to release the lock mechanism at the time of use, the release prohibiting mechanism that enables the lock mechanism to be released is activated, and then the lock mechanism is released. You have to do it in two steps,
The lock will never be released. Therefore, the lock mechanism is not inadvertently released, and the lock mechanism can be released only when the intention is to release the lock mechanism. Therefore, when you try to fold the umbrella stand by releasing the lock mechanism, that is, when you change the state from the used state to the unused state, always hold your finger in a safe place so as to avoid the part where there is a risk of jamming your finger. You can consider how to go. Therefore, it is possible to eliminate problems such as stuffing fingers when folding.

Further, interposed a post, a spacer having a predetermined width between the upper frame and the lower frame is supported by the posts
Therefore , even if the upper frame and the lower frame are rotated with respect to the support so that they are substantially overlapped with each other, the width of the spacer is always kept between the support and the upper and lower frames. Since a corresponding gap is generated, the upper frame body and the lower frame body will not come into contact with the support columns. Therefore, by setting the width of this spacer to be at least the thickness of an adult's finger, it is possible to more reliably prevent the situation in which the support column, the upper frame body, and the lower frame body are packed with fingers.
