Abstract: The device for holding an article according to the present invention comprises an external frame member defining a chamber and having an opening at one end thereof, and a resilient holding member mounted within the chamber and capable of holding an article which has been introduced into the chamber. The resilient holding member is mounted on the external frame member of the chamber such that the article is held by the resilient holding member in a desired position at a central portion of the chamber.

Description: The present invention relates to a device for holding an article, and more particularly to a device for holding an article with an external frame member defining a chamber and having an opening at one end thereof and a plurality of resilient holding members mounted within the chamber and capable of holding an article which has been introduced into the chamber. Such a device is known from US-A-50 14 868. The external frame member is a cup-shaped cylindrical receptacle or shell and the resilient holding members are insert members with deflectable flap portions. The insert members are detachably secured to the shell by equally spaced rails. The flap portions are hinged or joined at the insert members to permit pivotal deflection by its free edges for introducing and holding an article. In view of US-A-50 14 868, it is an object of the invention to provide a device for holding an article that can reliably hold articles of various shapes, one at a time,by a simple construction such that the article can be freely inserted and removed from the device while maintaining a correct, upright position. This object is achieved by a device for holding an article as outlined in claim 1. Further known is a device for holding an article such as that disclosed in the Official Gazette of Japanese laid-open patent application 3-98826. This device for holding an article comprises an external frame and a diaphragm portion mounted on the external frame through a closed space formed therebetween. When the article is placed within the external frame, pressurized air is supplied to the closed space by an air supply/discharge mechanism disposed on the transfer path so that the diaphragm portion is expanded to closely contact and hold the article. For removing the article from the external frame, the air introduced into the closed space by the air supply/discharge mechanism is discharged, whereby the diaphragm portion contracts. As a consequence, the close contact between the diaphragm and the article is eliminated to facilitate the easy removal of the article. However, although the device for holding the article is described in Japanese laid-open patent application 3-98826 is capable of holding articles having different shapes, it has the problem that, since an air supply/discharge mechanism must be provided for supplying and discharging pressurized air to and from the closed space in order to hold the article, the whole device becomes complicated. According to the invention, the upper ends of the resilient holding members are mounted on the external frame member and the opening portion of the external frame member is not narrow, thus facilitating the insert and removal of the article. The resilient holding members play a part of a guide when inserting and removing the article. As the resilient holding members are not fixed in the central areas thereof and protrude inwardly in this area, they can deform in accordance with the size and shape of the article and closely contact the article, due to the restoring force to the deformation, thereby reliably holding the article. That is, the device of the present invention can cope with articles of different size and shape. The plurality of resilient holding members are mounted so as to hold the article in an upright position at a central position of the chamber, so that the center axis of the article to be held can be oriented. Advantageous embodiments of the invention are disclosed by the features of the subclaims. For example, two of the resilient holding members can be disposed on each of opposing inner surfaces of the external frame member. The resilient holding members can be made of a member having a generally X-shaped configuration in development and a slit formed generally in the central area thereof and in the horizontal direction, such that the resilient holding member itself can be readily and resiliently deformed. In another embodiment of the present invention, four or more of the resilient holding members are provided in such a manner that the device can cope with two or more different shapes of the article.

DETAILED DESCRIPTION OF THE INVENTION One embodiment (first embodiment) of the device for holding an article according to the present invention will be described with reference to the drawings. Fig. 1 is a plan view of this embodiment (first embodiment) in which an article is held in the device; Fig. 2 is a sectional view taken along line A-A of Fig. 1; and Fig. 3 is a sectional view showing a method for inserting and holding an article according to this embodiment (first embodiment). The device for holding an article according to this embodiment (first embodiment) is shown in Figs. 1 and 2 and comprises an external frame member 1 having an opening portion 11a facing upwardly, and four resilient holding members 2, 2 · · mounted within the external frame member 1. The resilient holding members 2, 2 · · are mounted on the external frame member 1 such that they are arranged on inner surfaces of four corners of the external frame members 1 over the entire length thereof in a vertical direction with surfaces 21, 21 · · of the resilient holding members 2, 2 · · faced toward the center of the external frame member 1. The device for holding an article according to this embodiment (first embodiment) of the present invention will now be described in more detail. The external frame member 1 comprises an upper surface frame 11, four columns 12, 12 · ·, and a bottom surface frame 13. The upper surface frame 11 has a generally regular square frame configuration. The above-mentioned opening 11a, which has an octagonal frame configuration, is formed in a central portion of the upper surface frame 11. Connecting portions 11b, 11b · · are formed on the four corners of the upper surface frame 11, respectively. The connecting portions 11b, 11b · · function as connecting parts on upper ends of the columns 12, 12 · ·, respectively and also as reinforcing parts for enhancing the strength of the overall upper surface frame 11. The bottom surface plate 13 is a plate having a generally same configuration as the outer configuration of the upper surface frame 11. Upper ends of the columns 12, 12 · · are connected to the connecting portions 11b through one end of the respective, resilient holding members 2, and the lower ends of the columns 12, 12 · · are connected to the four corners of the bottom surface plate 13 through the other ends of the respective, resilient holding members 2. Each column 12 is a hollow tube and secured to the upper surface frame 11 and the lower surface plate 13 through a common bolt 12a and nut 12b. The sizes of the upper surface frame 11 and the bottom surface plate 13 are determined by the size and shape of the article 3 to be transferred. The size of the opening portion 11a is designed to be sufficiently larger than the outer configuration in plan view of the article 3. Similarly, the height of the external frame member 1 is determined considering the height and shape of the article 3 to be transferred. This height can be adjusted by adjusting the length of each column 12. One of the resilient holding members 2, 2 · · mounted on the plurality of locations will be described as one example. The remaining resilient holding members 2 will also have the same construction. No limitation is imposed on the material of the resilient holding member 2 as long as the material can exhibit resiliency toward the center of the external frame member 1 when the resilient holding member 2 is mounted on the external frame member 1. Examples of the material include the same material as that of a general conveyor belt, a material made of synthetic resin such as an acrylic resin or a polyester resin, a metal such as stainless steel or a spring steel, paper, cloth, rubber and the like. These materials, when used as the resilient holding member 2, are formed into a belt-shaped member. The width of the resilient holding member 2 is preferably 10 mm to 30 mm. The upper surface 21 of the resilient holding member 2, which is in surface contact with one side surface of the article 3, is a flat and smooth surface, so that the article 3 can easily be inserted from above into the space defined by the resilient holding members 2, 2 · · which are mounted on a plurality of locations within the external frame member 1. The plurality of locations, where the resilient holding members 2, 2 · · are mounted, are arranged at predetermined intervals. In this embodiment, the locations are arranged at predetermined intervals at the apexes of the upper surface frame 11 and the bottom surface plate 13. The length of the resilient holding members 2, 2 · · is determined in accordance with the size and shape of the article 3 to be transferred, so that when the article 3 is held in the external frame member 1, the resilient holding members 2, 2 · · are deformed and the side surfaces of the article 3 are held by the resilient restoring force thereof. If the length of the resilient holding members 2, 2 · · is too short, deformation of the resilient holding members 2, 2 · · becomes small when the article 3 is held, so that the resilient restoring force is not sufficient enough to hold the article 3. In contrast, if the length of the resilient holding members 2, 2 · · is too long, deformation of the resilient holding members 2, 2 · · becomes large when the article 3 is held, so that the resilient restoring force becomes too strong to allow the article 3 to be inserted smoothly into the external frame member 1. In order to hold the article 3 by the device according to the embodiment as shown in Fig. 3(a), the article 3 is inserted into the opening portion 11a from above the external frame member 1. At that time, the resilient holding members 2, 2 · · are resiliently deformed, as shown in Fig. 3 (b), by its dead weight or by the inserting force of an inserting mechanism for article 3. When the article 3 is inserted so far as to contact the bottom surface plate 13, as shown in Fig. 3 (c), the resilient holding members 2, 2 · · are inclined to be restored to their original shape by their resilient restoring force. As a consequence, the surfaces 21, 21 · · are caused to contact the side surfaces of the article 3, so that the article is urged toward the center of the external frame member 1 from four directions. In this way, the article 3 is held by the resilient holding members 2, 2 · ·. Since the device for holding an article according to this embodiment (first embodiment) of the present invention is thus constructed, as shown in Figs. 4(a) to 4(d), the resilient holding members 2, 2 · · are deformed in accordance with the various shapes of the articles 3, and the side surfaces of the articles 3 can be reliably held by the surfaces 21, 21 · · of the resilient holding members 2, 2 · · from a plurality of directions, without the need of a complicated supporting structure. Furthermore, since the side surfaces of the articles are held by the surfaces of the resilient holding members 2 from a plurality of directions, the articles can be held in their correct upright position without being moved. Moreover, since the device is of a simple construction, formed of the external frame member 1 and the resilient holding members 2, the article holding device itself is not very complicated. Thus, repair and changes of the mounting shape of the resilient holding members 2 can be made with ease. Since the resilient holding members 2 are arranged in a plurality of locations at predetermined intervals, the article 3 is urged toward the center of the external frame member 1 from a plurality of directions with predetermined intervals and is reliably held therein. Next, the most preferred embodiment (second embodiment) of the present invention will be described with reference to the drawings. Fig. 5 is a plan view of this embodiment (second embodiment), in which no article is yet held by the device; Fig. 6 is a sectional view taken along line B-B of Fig. 5; Fig. 7 is a sectional view taken along line C-C of Fig. 5; and Fig. 8 is a perspective view of this embodiment (second embodiment), in which an article is held by the device. The device for holding an article according to this embodiment (second embodiment) is different from that of the first embodiment in that an external frame member 1 comprises, as shown in Figs. 5 to 7, an upper member 14, an intermediate member 15 and a lower member 16. Two resilient holding members 2, 2 are mounted on the external frame member 1 at four places in total, two at the upper parts and two at a lower part thereof. As shown in Fig. 8, the external frame member 1 according to this embodiment (second embodiment) comprises the upper member 14, the intermediate member 15 and the lower member 16. These three component members have generally an octagonal configurations in plan view, in which four apex portions of a regular square are cut away. The upper member 14 is a member corresponding to the upper surface frame 11 of the first embodiment and has an octagonal opening portion 14 formed in a central portion thereof and similar to the opening portion 11a formed in the upper surface frame 11. The widths of two sets of opposing sides are increased, and bolts 15a as later described are positioned in the increased width portions (i.e., the sides of increased width). The intermediate member 15 corresponds to columns 12 of the first embodiment. The intermediate member 15 comprises a frame-like portion and vertical portions erected from portions of the frame-like members corresponding to the increased width portions. The lower member 16 corresponds to the bottom surface plate 13 of the first embodiment. The lower member 16 comprises a bottom surface portion and connecting portions erected from the increased width portions and portions corresponding to the vertical portions. An opening portion 16a is formed in the center of the bottom surface portion. Each resilient holding member 2 has a generally X-shaped configuration and has a horizontally extending slit 2a formed in the central area thereof so that the resilient holding member 2 itself can be readily deformed. The resilient holding member 2 is formed of a material having a duplicate layer construction. A layer on the side of the upper surface 21 is formed of a layer of a material having a good sliding property, whereas the other layer on the side of the lower surface is formed of a layer of material having a favorable property for exhibiting a resilient restoring force. Fine concavities and convexities are formed on the upper surface 21 of the resilient holding member 2 in order to further enhance the sliding property. Due to the concavities and convexities, the area of the upper surface 21 of the resilient holding member 2, which contacts the side surface of the container 3, is reduced. As shown in Fig. 7 (second embodiment), the upper ends of the resilient holding members 2, 2 are sandwiched between the upper member 14 and the intermediate member 15, and lower ends of the resilient holding members 2, 2 are sandwiched between the intermediate member 15 and the lower member 16. These component members are integrally assembled, as shown in Fig. 8, by bolts 15a, 15a · · which extend from the upper member 14 to the lower member 16. When assembled, the resilient holding members 2, 2 are mounted in their inwardly flexed states in accordance with the size of the article 3. The device for holding an article according to this embodiment (second embodiment) is thus constructed, and is used in the same manner as the device according to the first embodiment. According to the device for holding an article according to this embodiment (second embodiment), the side surface of the article can be more widely held from the side. When the article has unusual shapes, the holding device of the second embodiment can hold the article better than that of the first embodiment. Further, according to the device for holding an article of this embodiment (second embodiment), since the opening portion 16a is formed in the center of the lower member 16, the article can be pushed out from under when the article 3 is taken out of the device. In addition to the arrangements mentioned above, the resilient holding members 2, 2 · · may have the arrangements as shown in Figs. 9(a) to 9(h): Figs. 9(a) and 9(b) show arrangements in which the resilient holding members 2, 2 · · are disposed such that the article 3 is held from two directions. Figs. 9(c) and 9(d) show arrangements in which the article 3 is held from three directions. Figs. 9(e) to 9(g) show arrangements in which the resilient holding members 2, 2 · · are disposed such that the article 3 is held from four directions. Fig. 9(h) shows an arrangement in which the article 3 is held from five directions. The arrangement of the resilient holding members 2, 2 · · is determined based on the shape of the article to be held. In the embodiments shown in Figs. 9(a) to 9(h), the resilient holding members 2, 2 · · are mounted, either directly or through mounting sections of the columns 12, 12 · · of the external frame member 1, on the external frame member 1. Other portions of the embodiments shown in Figs. 9(a) to 9(h) are exactly the same in construction as the embodiments shown in Figs. 1 and 2. Besides the above-mentioned mounting shapes in which a single resilient holding member 2 is used for a single mounting location and two resilient holding members 2 are used for four mounting locations, the mounting form of the resilient holding members 2, 2 · · may be varied according to the shape of the article to be held, as shown in Figs. 10(a) to 10(c). Fig. 10(a) shows another embodiment in which the upper portion of one of opposing resilient holding members has a double wall and the lower part of the other resilient member also has a double wall. According to this embodiment, the holding force of said upper portion is increased and holding force of said lower portion is also increased. Fig. 10(b) shows a further embodiment in which one of the opposing resilient holding members has a double wall. In this embodiment, three of the resilient holding members correspond to the shape of the article, and the upper portions and lower portions are separately doubled. Fig. 10(c) shows a still further embodiment in which upper portions of both opposing resilient holding members are doubled to increase the holding force with respect to the upper portion of the side surfaces of the article. Thus, since the resilient holding members 2 are partly or entirely double walled at places where the resilient holding members 2 are mounted, the holding force of the resilient member 2 can be finely adjusted in accordance with the shape of the article, and therefore the article can be held more reliably. Mounting forms of the resilient holding members not shown in Figs. 10(a) to 10(c) are determined according to the shape of the side surfaces of the article. The mounting forms are selected appropriately from that shown in Fig. 2, that shown in the right side of Fig. 10(a), that shown in the left side of Fig. 10(b), that shown in the right side of Fig. 10(b), that shown in Fig. 10(c), and their partly modified embodiments. By changing the arrangement and mounting of the resilient holding member, the device can cope with a variety of article shapes and hold the article more reliably. Figs. 11 to 14 show a third embodiment of the device for holding an article according to the present invention. The device for holding an article according to this embodiment (third embodiment) is constructed in a similar manner as the device for holding an article of the second embodiment. An external frame member 1 of the device comprises an upper member 14, an intermediate member 15, and a lower member 16. In this respect, the external frame member of the third embodiment is not different from the external frame member of the second embodiment. However, the external frame 1 of this embodiment (third embodiment) is so dimensioned as to be capable of receiving and holding an article as shown in Fig. 13. Accordingly, this embodiment (third embodiment) has a generally rectangular configuration in plan view. The intermediate member 15 is formed with a sleeve-like construction, and the lower member 16 is formed in a tub-like construction. Since the device for holding an article according to this embodiment (third embodiment) does not have an opening portion in its side surface, unlike the device for holding an article according to the second embodiment, the device of the third embodiment has the box-like construction of Fig. 13 when it is assembled using bolts 15a, 15a · ·. As the resilient holding member, two kinds of holding members 2 and 2' are employed. One kind of the resilient holding members has a generally H-shaped configuration. Diamond-like holes 2b, 2b' are formed in the central areas of the resilient holding members so that the resilient holding members themselves can be readily deformed. The other resilient holding members 2', 2' each has a belt-like configuration. Both the resilient holding members 2 and 2' are of a duplicate layer construction and concavities and convexities are formed on the surfaces 21 as in the case with the second embodiment. As in the case with the device for holding an article according to the second embodiment, the upper ends of the resilient holding members 2, 2' are sandwiched between the upper member 14 and the intermediate member 15, respectively, and the lower ends of the resilient holding members 2, 2' are sandwiched between the intermediate member 15 and the lower member 16, respectively. These component members are integrally assembled, as shown in Fig. 13, by bolts 15a, 15a · · which extend from the upper member 14 to the lower member 16. The device for holding an article according to this embodiment (third embodiment) can receive and hold such an article having the shape as shown in Fig. 13. It can also receive and hold such an article 3' of a different shape as shown in Fig. 14. Thus, the device for holding an article according to this embodiment (third embodiment) can receive and hold an article of different shapes without changing any construction thereof. Figs. 14 and 15 show a fourth embodiment of a device for holding an article according to the present invention. The device for holding such an article is also constructed in a similar manner as the device of the second embodiment. However, an external frame member 1 in this embodiment (fourth embodiment) comprises an upper member 14, a first intermediate member 15, a second intermediate member 15', and a lower member 16. That is, the intermediate member 15 of the second embodiment is divided into a vertical portion serving as the first intermediate member 15 and a frame-like portion serving as the second intermediate portion 15'. The resilient holding members are mounted on four corners of the external frame member 1. The resilient holding members 2 and the resilient holding members 2' are mounted on the respective mounting portions in their overlapped states. Both the resilient holding members 2 and 2' are of a belt-like configuration but different in length from each other. The upper ends of the resilient holding members 2, 2' are sandwiched between the upper member 14 and the first intermediate member 15, respectively, and the lower ends of the resilient holding members 2' are sandwiched between the first intermediate member 15 and the second intermediate member 15', respectively. The lower ends of the resilient holding members 2 are sandwiched between the second intermediate member 15' and the lower member 16. Those component members are integrally assembled, as shown in Fig. 16, by bolts 15a, 15a · · which extend from the upper member 14 to the lower member 16. Fig. 17 shows a fifth embodiment of a device for holding an article according to the present invention. This device is also constructed in a similar manner as the device for holding an article according to the second embodiment and has a single resilient holding member 2 of the type in which two resilient holding members of the second embodiment are connected with each other at the sides thereof. The device for holding an article according to the present invention is not limited to the above embodiments. Although the external frame member 1 has a generally regular square shape or a generally octagonal shape in plan view, it may also have, for example, a circular shape or many other polygonal shapes. The number of the columns 12, 12 · · and the manner in which they are constructed and connected are not limited to the above embodiments. The number, the material and the configuration of the resilient holding members 2 (and 2') are not limited to the above embodiments. In the above embodiments, for example, the thickness of the resilient holding members 2 (and 2') is constant. However, the thickness and width of the resilient holding members 2 (and 2') may be changed so that the holding force can be changed. The articles 3 (and 3') held by the device are containers for detergents and the like. However, it goes without saying that the types of articles have no limit. Also, the materials of the resilient holding members 2, 2' may be mutually applied in the respective embodiments. Other features may also be changed or modified, if necessary, without departing from the scope of the present invention as claimed.
