The present invention aims to solve the above-mentioned problems.

[Means for Solving the Problem] In order to achieve the above object, the present invention provides a retractable umbrella stand device that includes a stationary umbrella stand main body, first and second movable umbrella stand main bodies, a base member, The arm is equipped with a rotating support arm consisting of an intermediate member and a tip member, an intermediate member drive mechanism, and a tip member drive mechanism, and the stationary umbrella stand main body and both movable umbrella stand main bodies have an umbrella insertion opening on the top surface. The rotating support arm has an intermediate member and a distal end member slidable relative to the proximal end member, and the proximal end of the proximal end member is pivotally attached to the side wall portion of the stationary umbrella stand main body. The first movable umbrella stand main body is pivotally supported on the intermediate member in the attached state,
Furthermore, the second movable umbrella stand main body is pivotally supported by the tip member, and the intermediate member drive mechanism moves the intermediate member in the longitudinal direction with respect to the base end member using the rotational movement of the rotational support arm. The tip member driving mechanism is configured to be able to slide the tip member in the longitudinal direction with respect to the intermediate member using the sliding movement of the intermediate member, and the tip member drive mechanism is configured to make the tip member slide in the longitudinal direction with respect to the intermediate member. is rotated from a use position in which the first and second movable umbrella stand bodies are sequentially arranged adjacent to the front of the stationary umbrella stand body to a storage position in which they are suspended and supported above. It is characterized by the fact that it is made to obtain.

In addition, in order to obtain an appropriate guiding action with a simple configuration, the intermediate member drive mechanism is provided with a cam groove provided in the side wall portion of the stationary umbrella stand main body, and a cam groove provided protrudingly on the intermediate member. It is preferable to have a cam follower engaged with the groove,
Further, the distal end member drive mechanism includes a fixed rack fixed to the proximal end member, a movable rack fixed to the distal end member and opposed to the fixed rack, and the fixed rack and the movable rack pivoted to the intermediate member. It is preferable to have a pinion that meshes with both of the pinions.

Preferably, the device comprises a movable rack and a two-stage pinion that is pivotally attached to the intermediate member and meshes with both the fixed rack and the movable rack at different radii.

[Function] With this configuration, when an umbrella stand is required, the rotation support arm is operated to sequentially move the first and second movable umbrella stand bodies forward of the stationary umbrella stand body. By arranging them adjacent to each other, the umbrella insertion slots on the top of the umbrella stand will open at positions suitable for putting in and taking out umbrellas, making it possible to use them in a much larger area than when they are permanently installed. If the umbrella stand is not required, the first and second movable umbrella stands can be suspended and supported above the stationary umbrella stand by operating the rotating support arm, so that the umbrella stands are vertical. This allows for storage in a much smaller area than when in use.

Moreover, by utilizing the rotational movement to appropriately slide the intermediate member relative to the base member and further slide the distal end member relative to the intermediate member, each umbrella stand body can be adjusted in both the use position and the storage position. At the same time, it is possible to effectively avoid contact and interference between the umbrella stand bodies during the rotation operation.

[Example] Hereinafter, an example of the present invention will be described with reference to FIGS. 1 to 5.

Fig. 1 is a front view of the retractable umbrella stand device according to the present embodiment, Fig. 2 is a left side view of the same, Fig. 3 is a partially enlarged sectional view taken along the line - in Fig. 2, and Fig. 4 is a 3
5 is an enlarged sectional view taken along the line - in FIG. 4. FIG. As shown in these drawings, this umbrella stand device includes a stationary umbrella stand main body 1, first and second movable umbrella stand main bodies 2 and 3, and left and right side wall portions of these umbrella stand main bodies 1 to 3. It comprises a pair of rotation support arms 4, 4 arranged, and an intermediate member drive mechanism 5 and a tip member drive mechanism 6 that are integrally formed with the rotation support arms 4.

The stationary umbrella stand main body 1 is box-shaped with an open top surface, and partition members 11 are horizontally suspended on the top surface in a grid pattern to form a plurality of umbrella insertion openings 1a. Each umbrella insertion opening 1a is provided with a shape and size that can accommodate, for example, several umbrellas at the same time. Moreover, the first and second movable umbrella stand bodies 2 and 3 are also box-shaped with open top surfaces, and have a plurality of umbrella insertion openings 2a and 3 using partition members 21 and 31 on their top surfaces, respectively.
A, each of which can accommodate several umbrellas. Then, the stationary umbrella stand main body 1 is fixedly attached between the side plates 7, 7 which are set up in a pair on the floor F, and the first and second The movable umbrella stand main bodies 2 and 3 are sequentially arranged.

As shown in FIGS. 3 to 5, the rotation support arm 4 includes a long base end member 41 having a U-shaped cross section.
, an intermediate member 42 in the shape of an H steel material shorter than this, and a tip member 43 in the shape of a square bar. The members 43 are slidably fitted together. In such a fitted state, the pin-shaped cam follower 42a rotatably attached to the intermediate member 42 and the intermediate member 4
Pivot pins 42b integrally protruding from the base member 2 are inserted through the inner openings 41a of the proximal end member 41 and extend inward. Further, a pivot pin 43a integrally protruding from the tip member 43 extends inward from the tip portion that is not fitted.
The proximal end portion of the proximal member 41 is rotatably connected to the side plate 7 via the shaft support 4a, and the first
The second movable umbrella stand main body 2 is pivotally supported between the pins 43a, 43a of the tip member 43. It should be noted that a weight (not shown) for preventing rotation is attached to the bottoms (below the pivot points) of both movable umbrella stand bodies 2, 3.

Then, the sliding operation of the intermediate member 42 is performed as follows.
This is provided by the intermediate member drive mechanism 5. This intermediate member drive mechanism 5 is composed of the aforementioned cam follower 42a and a cam groove 71 recessed in the outer surface of the side plate 7 (see FIG. 2), and the cam follower 42a is rotatably engaged with the cam groove 71. It will be combined. As a result, when the proximal member 41 rotates, the cam follower 42a performs a learning motion along the cam groove 71, and this motion is transmitted to the intermediate member 42. As a result, the intermediate member 42 moves along the cam groove 71.
The guide is always guided to a predetermined slide position corresponding to the rotational position according to the groove shape. This device is designed to be stable when the first and second movable umbrella stand bodies 2 and 3 are sequentially arranged adjacent to each other with a predetermined gap in front of the stationary umbrella stand body 1, as shown by the solid line in FIG. Cam groove 71 and cam follower 4 in this part
2a is the starting end a of the cam groove 71,
As shown by the two-dot chain line in the figure, the cam at this part is designed to stabilize when the first and second movable umbrella stand bodies 2 and 3 are suspended and supported above the stationary umbrella stand body 1 with a predetermined gap. The engagement position between the groove 71 and the cam follower 42a is the terminal end b of the cam groove 71 (also, the terminal end b
The cam groove 71 is further provided to prevent the first movable umbrella stand main body 2 from contacting or interfering with the stationary umbrella stand main body 1 during the rotation operation.
The section between the starting end a and the ending end b is appropriately curved.
Incidentally, in this embodiment, contact/interference between the first movable umbrella stand main body 2 and the stationary umbrella stand main body 1 is most likely to occur at the position shown by the dashed line in the figure. For this reason,
The cam groove 71 is in this position, and the cam follower 42a is
It is recessed at a point d farthest from the rotation center m of the rotation support arm 4 so that it can be guided to the farthest distance.

Further, the sliding motion of the tip member 43 is provided by the tip member drive mechanism 6. As shown in FIGS. 3 to 5, this distal member drive mechanism 6 includes a fixing rack 61 fixedly installed in the hollow of the proximal end member 41 along the longitudinal direction, and a fixing rack 61 fixed at the rear end of the distal end member 43. It is composed of a movable rack 62 which is fixedly installed and faces the fixed rack along the longitudinal direction, and a pinion 63 which is pivoted to the intermediate member 42, and the pinion 63 is meshed with both the fixed rack 61 and the movable rack 62. There is. As a result, when the intermediate member 42 slides, for example, in the right direction in FIG. At this time, the movable rack 62 engaged on the opposite side is pushed forward at a relative velocity v, so that the distal end member 43 that is integrated with the movable rack 62 is moved so that the intermediate member 42 is connected to the proximal end member 41. On the other hand, by sliding at a speed v, the base end member 41 slides at a speed 2v. Therefore, the second movable umbrella stand main body 3, which is disposed adjacent to the first movable umbrella stand main body 2 with a suitable gap as shown by the solid line in FIG. The umbrella stand is slid to the maximum extent at the part where contact/interference is most likely to occur (indicated by the one-dot chain line), and then suspended above the first movable umbrella stand main body 2 at an appropriate interval again at the storage position (indicated by the two-dot chain line). It will be supported.

However, with such a configuration, when an umbrella stand is required, the movable umbrella stand main bodies 2 and 3 are sequentially placed adjacent to the stationary umbrella stand main body 1 by operating the rotation support arm 4. By doing so, those umbrella stands 1~
As the upper surface of 3 faces forward, it is gently tilted forward and the umbrella insertion openings 1a, 2a, and 3a are opened flush, making it easy to insert and remove an umbrella from any of the umbrella insertion openings 1a to 3a. In addition, when an umbrella stand is not required, by operating the rotation support arm 4 to suspend and support the movable umbrella stand bodies 2 and 3 above the stationary umbrella stand body 1, the umbrella stand bodies 2 and 3 can be suspended and supported. 1 to 3 overlap in the vertical direction, allowing a storage form that does not take up much space. Moreover, the first movable umbrella stand main body 2 is moved by the intermediate member drive mechanism 5, and the second
The movable umbrella stand main body 3 is guided to the appropriate sliding position by the intermediate member drive mechanism 5 and the tip member drive mechanism 6, respectively, as described above, so that each of the umbrella stand main bodies 1 to 3 can be moved between the use position and the storage position. are arranged at appropriate intervals under stable conditions, and the rotational movement between them will be performed smoothly from beginning to end without any trouble. Therefore, if this retractable umbrella stand device is permanently installed at the entrance of an office or hall, it can be stored in an area equivalent to that of the stationary umbrella stand main body 1 without interfering with traffic. By simply unfolding it, many umbrellas can be accommodated in an area approximately three times larger than when installed, making it extremely convenient to use.

One embodiment of the present invention has been described above, but
The configuration of each part is not limited to the illustrated example.
For example, as shown in FIG. 6, the distal member drive mechanism 106 is connected to a fixed rack 161 fixed to the proximal member 141 and a movable rack 162 fixed to the distal end member (not shown) and disposed opposite to the fixed rack 161. It is also effective to have a two-stage pinion 163 which is pivotally attached to the intermediate member 142 and meshes with both the fixed rack 161 and the movable rack 162 at different radii r ₁ and r ₂ , respectively. According to this configuration, it is possible to appropriately set the sliding speed of the tip member relative to the sliding speed of the intermediate member 142 by the radius ratio r ₁ /r ₂ , so that the operating position, storage position, and It becomes possible to more accurately adjust the rotation locus and the like. Further, in order to prevent the movable umbrella stand from rotating, a parallel link or the like may be used to correct the posture.

[Effects of the invention] Due to the structure described above, the retractable umbrella stand device of the present invention can greatly reduce the installation area of the entire device when an umbrella stand is not required. In some cases, the entire usable area of the device can be expanded, so even if it is permanently installed on the floor, it can be stored compactly and used effectively as a highly functional device that can exert great power when in use. becomes possible. Moreover, the operability at that time,
The stability of both movable umbrella stand bodies is also sufficiently ensured.
