Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a retractable umbrella stand that can be suitably employed when storing a large number of umbrellas.

[Prior art] Umbrella stands of this type include box-shaped ones and cylindrical ones that have a bottom plate that also serves as a water receptacle, and are permanently installed in entrances of offices, halls, etc., or hallways. It is starting to be used. There are also examples where the device is placed in the entrance or hallway only when necessary, and when it is not needed, it is carried to a designated room and put away.

[Problem that the invention aims to solve] However, this type of umbrella stand is designed to store a large number of umbrellas, so it is relatively large and its shape can be changed as needed. It cannot be changed. Therefore, if such an umbrella stand is placed at the entrance, hallway, etc. of an office or hall, it not only spoils the appearance of the surrounding area, but also tends to obstruct traffic. This problem is especially noticeable in places where several umbrella stands are needed, and it is also difficult to move them to a predetermined location as needed.

The purpose of this invention is to eliminate the above-mentioned problems.

[Means for Solving the Problems] In order to achieve the above object, the present invention includes a retractable umbrella stand device comprising a stationary umbrella stand body, a movable umbrella stand body, and a rotating support arm. In addition, the stationary umbrella stand main body and the movable umbrella stand main body are box-shaped with an umbrella insertion opening on the top surface, and the base end of the rotation support arm is pivoted on the side wall of the stationary umbrella stand main body or in the vicinity thereof. and with the movable umbrella stand main body disposed in front of the stationary umbrella stand main body, the side wall portion of the movable umbrella stand main body is pivotally connected to the rotation support arm, and the rotation support arm is connected to the movable umbrella stand main body. The umbrella stand is characterized in that it is provided so that it can be rotated from a use position where it is disposed adjacent to the front of the stationary umbrella stand body to a storage position where it is suspended and supported above.

In addition, when it is necessary to guide the movable umbrella stand main body by drawing an appropriate trajectory relative to the stationary umbrella stand main body for rotational operation, the rotation support arm is attached to the base end which is pivotally connected to the stationary member. and a distal end member slidably held on the proximal end member, and a movable umbrella stand main body is pivotally supported on the distal end member, and the pivot support arm is pivoted. It is preferable to provide a distal member driving mechanism for sliding the distal end member in the longitudinal direction with respect to the proximal end member using the motion.

Furthermore, in order to easily configure the tip member drive mechanism, the tip member drive mechanism is configured by using a cam groove provided in the stationary member and a cam follower that is provided protruding from the tip member and engaged with the cam groove. It is better to have something that is fully equipped.

[Function] With such a configuration, when an umbrella stand is required, the movable umbrella stand body can be placed adjacent to the front of the stationary umbrella stand body by operating the rotation support arm, and the umbrella stand can be placed adjacent to the stationary umbrella stand body. The umbrella insertion slots provided on the top of the umbrella stand are all opened at positions suitable for putting in and taking out umbrellas, making it possible to use a much larger area than when it is permanently installed, and eliminating the need for an umbrella stand. In such cases, by operating the rotating support arm to suspend and support the movable umbrella stand above the stationary umbrella stand, the umbrella stands overlap and occupy a much smaller space than when in use. It becomes possible to store the area.

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

Figure 1 is a front view of the retractable umbrella stand device;
The figure is the same left side view, and Fig. 3 is the same as Fig. 2.
FIG. As shown in these drawings, this umbrella stand device includes a stationary umbrella stand main body 1, a first
It comprises second movable umbrella stand main bodies 2, 3 and a pair of rotating support arms 4, 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 has a shape and size that can accommodate, for example, several umbrellas at the same time. Further, the first and second movable umbrella stand bodies 2 and 3 are also box-shaped with open tops, and a plurality of umbrella insertion openings 2a and 3a are formed on the top surfaces using partition members 21 and 31. However, each can accommodate several umbrellas. and,
The stationary umbrella stand main body 1 is attached and fixed between side plates (stationary members) 5, 5 arranged in a pair on a floor surface F,
The first and second movable umbrella stand main bodies 2 and 3 are sequentially disposed ahead of the movable umbrella stand via a rotation support arm 4.

The rotation support arm 4 has a base end member 4 in the shape of a square timber.
1 and a square-shaped tip member 42 of a size that can be inserted into the base end member 41 are fitted telescopically. Holes 41a and 41b are bored. The tip member 42 also includes a pin-shaped cam follower 4 that extends inwardly through the elongated hole 41a while being fitted into the base member 41.
2a is rotatably mounted, and a pivot pin 42b extending inwardly through the elongated hole 41b and a pivot pin 42c extending inwardly from the distal end protrude. It is set up. The proximal end portion of the proximal member 41 is rotatably connected to the side plate 5 via the shaft support 6, and the distal end member 42
between the pins 42b and 42b of the first movable umbrella stand main body 2
Further, the second movable umbrella stand body 3 is pivotally supported between pins 42c, 42c. Note that a weight (not shown) for preventing rotation is attached to the bottom of the movable umbrella stand main bodies 2, 3 (below the pivot points).

Then, the sliding operation of the tip member 42 is performed as follows.
This is provided by a tip member drive mechanism 7. This tip member drive mechanism 7 is composed of the above-described cam follower 42a and a cam groove 51 recessed in the outer surface of the side plate 5.
is rotatably engaged with the cam groove 51. As a result, when the base end member 41 is rotated, the cam follower 42a performs a learning motion along the cam groove 51, and this motion is transmitted to the distal end member 42.
As a result, the tip member 42 is always guided to an appropriate sliding position in a unique relationship with the rotational position depending on the groove shape of the cam groove 51. In this device, as shown by the solid line in Fig. 2, the movable umbrella stand main body 2,
3 is placed adjacent to the stationary umbrella stand main body 1 at a predetermined interval, the engagement position of the cam groove 41 and the cam follower 42a at this portion is defined as the starting end a of the cam groove 51, and is designated as 2 in the figure. The cam groove 51 and cam follower 4 at this location are designed to stabilize the movable umbrella stand main bodies 2 and 3 when they are suspended and supported at a predetermined interval above the stationary umbrella stand main body 1, as shown by the dotted chain line.
2a is the terminal end b of the cam groove 51 (also, the vicinity c of the cam groove 51 leading to the terminal end b is inclined rearward), and furthermore, during the rotation operation, at least the stationary umbrella stand main body 1 The starting end a and the ending end b of the cam groove 51 are appropriately curved so that there is no contact or interference with the first movable umbrella stand main body 2. Incidentally, in this embodiment, contact/interference between the stationary umbrella stand main body 1 and the first movable umbrella stand main body 2 is most likely to occur at the position shown by the dashed line in FIG. For this reason,
The cam groove 51 is set at a point d farthest from the rotation center m of the rotation support arm 4 so that the tip member 42 can be guided to the most protruding portion at this position. Furthermore, the second movable umbrella stand main body 3 is slightly recessed at the rear corner 3a of the main body bottom to avoid contact and interference with the first movable umbrella stand main body 2.

With such a configuration, when an umbrella stand is required, the rotary support arm 4 is operated to arrange the movable umbrella stand bodies 2 and 3 adjacent to the sides of the stationary umbrella stand body 1. As a result, the upper surfaces of the umbrella stand bodies 1 to 3 are gently tilted forward and the umbrella insertion openings 1a, 2a, and 3a are opened flush. 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, when the umbrella can be easily taken in and taken out and an umbrella stand is not required, Since the umbrella stand bodies 1 to 3 overlap each other, a storage form that does not take up much space is achieved. Furthermore, due to the guiding action of the cam groove 51, these rotational operations are performed smoothly without any trouble, and the stability of the movable umbrella stand main bodies 2, 3 in the use position and storage position is also improved. For this reason, if this retractable umbrella stand device is permanently installed at the entrance of an office or hall, it can be stored so as not to obstruct traffic etc. normally on the surface equivalent to the stationary umbrella stand body 1, but when not in use. At times, it can be easily unfolded to accommodate many umbrellas in an area approximately three times larger than when it was installed, making it extremely easy to use.

In addition, the stationary umbrella stand body is 1
It is also possible to connect three or more if necessary. 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 and stability at that time can also be easily improved according to the present invention.
