Description

BACKGROUND OF THE INVENTION1. Technical Field

[0001] The present invention relates to a facility structure and more particularly to a facility structure whose vertical posts, crossbeam(s), and supporting rods can be assembled together through elements including insertional connection elements and elastic position-limiting portions, without using threaded fasteners.2. Description of Related Art

[0002] The current market environment is such that consumers have more expectations about outdoor structures and furniture products. In addition to esthetic and practicality, they are looking for convenience and sustainability of use. The existing products, however, often fail to meet those consumer requirements. A conventional product that is held together by screws tends to experience material fatigue and / or damage if disassembled and reassembled for multiple times. This not only reduces the durability of the product, but also increases the amount of waste, leading to a wasteful use of resources when it comes to environmental friendliness.

[0003] More specifically, products on the market nowadays generally have complicated structures and a lot of parts (e.g., screws, bolts, and nuts), both of which add to the difficulty of assembly, not to mention the possibility of losing one or more parts during daily use. A loss of parts often results in a customer complaint or even a request for product return or a refund, causing much trouble to both the product manufacturer and the distributor. Moreover, in order to assemble or disassemble products that use screws as connecting elements, consumers must prepare, or buy in most cases, the corresponding tools. Not only will this increase consumers' financial burden, but also the operation of tools (e.g., the steps of tightening and loosening screws) will complicate and prolong the assembly or disassembly process. Those who have insufficient physical strength or seldom engage in DIY activities will be greatly inconvenienced by the required operation and hence be unwilling to buy such products.

[0004] Furthermore, in view of the limitations of living spaces, and given the prevalence of a mobile way of life, consumers have an increasingly strong desire that their furniture and outdoor structures be able to be easily disassembled and reassembled to adapt to their daily living needs dynamically. Screws, however, tend to rust after long-term use or due to environmental factors, making it difficult to disassemble and reassemble a product with screws for a second time. This is without doubt a major disadvantage to products that have to be frequently moved from one place to another or put away seasonally. In particular, when moving to a new house or redecorating an outdoor space, a consumer may find that the aforesaid issue with screws has made convenient products difficult to handle or move. Trying to tackle with those products can be laborious, but leaving them as are will result in inefficient use of space.

[0005] According to the above, consumers' requirements for outdoor structures and furniture products are changing rapidly, and yet commercially available outdoor structures and furniture products are designed in a way that causes a lot of inconveniences. Their complex connecting structures, time-consuming assembly process, and hard-to-perform maintenance work in a later stage of their service life all have a certain negative effect on user experience. The issue to be addressed by the present invention, therefore, is to provide a product that can be assembled or disassembled with greater ease and is more convenient.BRIEF SUMMARY OF THE INVENTION

[0006] In light of the aforementioned problems associated with the use of screws to connect different elements of a facility structure such as an outdoor pavilion, and considering the increasing emphasis placed by consumers on effective use of time in response to a faster pace of life, the inventor of the present invention conducted an extensive research and repeated trials and finally succeeded in developing a facility structure capable of highly efficient insertional interconnection as disclosed herein.

[0021] The present invention provides a facility structure (e.g., a pavilion, a bulletin board, or another indoor or outdoor facility) capable of highly efficient insertional interconnection. Preferably, the facility structure is an outdoor facility, and the main elements of the facility structure are connected without having to use screws or other threaded fasteners. The facility structure is described below as a pavilion by way of example only, and the number of each type of element of the facility structure can be changed according to practical needs and may be plural or at least one. Referring to FIG. 1 to FIG. 3, the pavilion K includes a plurality of vertical posts 1, a plurality of crossbeams 2, a plurality of insertional connection elements 3, and a plurality of supporting rods 4. The bottom end of each vertical post 1 is configured to be fixed on a plane (e.g., on the ground). The top end of each vertical post 1 is provided with an insertion opening 11. Two adjacent sides of each vertical post 1 are each provided with a fixing groove 13. One side of each vertical post 1 that is not provided with a fixing groove 13 is provided with a through hole 15. Each vertical post 1 is further provided therein with a space 10 for insertional connection, wherein the space 10 for insertional connection is in communication at least with the insertion opening 11 and the through hole 15 of the vertical post 1. In some embodiments, a fixing groove 13 of each vertical post 1 can be formed by fixing another element to the outer wall of the vertical post 1. In some embodiments, a vertical post 1 can have a wall portion stamped outward from the inside to form a fixing groove 13.

[0022] With continued reference to FIG. 1 to FIG. 3, a crossbeam 2 can be connected between two adjacent vertical posts 1 such that the two vertical posts 1 are spaced apart by a distance. Each crossbeam 2 has two ends each provided with a lower fixing plate 21 that extends downward, and each lower fixing plate 21 of a crossbeam 2 can be inserted downward into a corresponding fixing groove 13 such that the crossbeam 2 is positioned on the vertical posts 1. In this embodiment, the pavilion K has four crossbeams 2. In certain embodiments of the present invention, however, the facility structure (e.g., a bulletin board with supporting posts) can be provided with only one crossbeam 2, and each vertical post 1 can have only one side provided with a fixing groove 13.

[0023] Referring to FIG. 4 and FIG. 5, each insertional connection element 3 is provided therein with a first elastic position-limiting portion 31 and a receiving space 30 for receiving the first elastic position-limiting portion 31, with a portion of the first elastic position-limiting portion 31 passing through a hole 300 of the insertional connection element 3 to be exposed from the insertional connection element 3, wherein the exposed portion of the first elastic position-limiting portion 31 is configured to be withdrawn into the insertional connection element 3 when subjected to an applied force. In this embodiment, a first elastic position-limiting portion 31 is a spring pin whose essential structures are briefly stated as follows. The spring pin at least includes a spring 311 and a position-limiting body 313, wherein: one end of the spring 311 abuts directly or indirectly against an inner wall of the insertional connection element 3, the opposite end of the spring 311 is used to push the position-limiting body 313 such that one end of the position-limiting body 313 is exposed from the hole 300 of the insertional connection element 3 (but kept from separating from the insertional connection element 3), and when the position-limiting body 313 is pushed by an external force great enough to overcome the force applied by the spring 311, the position-limiting body 313 is withdrawn into the insertional connection element 3. In certain embodiments of the present invention, however, a first elastic position-limiting portion 31 can be a V-shaped elastic fastener as shown in FIG. 6. More specifically, the V-shaped elastic fastener of the insertional connection element 3 can have a first end directly or indirectly positioned at / in an inner wall of the insertional connection element 3 and a second end passing through the hole 300 of the insertional connection element 3 to be exposed from the insertional connection element 3, wherein the second end of the V-shaped elastic fastener is configured to be withdrawn into the insertional connection element 3 when subjected to an applied force.

[0024] Referring to FIG. 3 to FIG. 5, each insertional connection element 3 is configured to be inserted downward through the insertion opening 11 of a vertical post 1 into the corresponding space 10 for insertional connection, and during this connecting process, the exposed portion (e.g., the position-limiting body 313) of the first elastic position-limiting portion 31 will be pushed by the inner wall of the vertical post 1 and therefore withdrawn into the insertional connection element 3 until corresponding in position to the through hole 15 of the vertical post 1, at which time the exposed portion (e.g., the position-limiting body 313) of the first elastic position-limiting portion 31 will extend into the through hole 15 and end up positioned therein, indicating that the insertional connection element 3 has been inserted and connected in place. Moreover, in order to increase the stability of each crossbeam 2 after assembly, referring to FIG. 3 to FIG. 5, the two ends of each crossbeam 2 in this embodiment are each further provided with an upper fixing plate 23. Once a lower fixing plate 21 of a crossbeam 2 is inserted into a corresponding fixing groove 13 of at least one of the vertical posts 1, the horizontal position of the top end of the corresponding upper fixing plate 23 of the crossbeam 2 is higher than the horizontal position of the top end of the at least one of the vertical posts 1. In addition, each insertional connection element 3 is peripherally provided with at least one positioning groove 315. After an insertional connection element 3 is connected to a vertical post 1, a positioning groove 315 of the insertional connection element 3 can receive the corresponding upper fixing plate 23 of a crossbeam 2 so that the engaging effect of the corresponding fixing groove 13 and of the positioning groove 315 ensures that the crossbeam 2 is securely fixed on the vertical post 1 and is thus effectively enhanced in stability after assembly.

[0025] In this embodiment, with continued reference to FIG. 3 to FIG. 5, each insertional connection element 3 is peripherally provided with at least one pressing portion 317 that extends outward and corresponds in position to a crossbeam 2 so that a user who is inserting an insertional connection element 3 downward into a vertical post 1 to which a crossbeam 2 has been connected will immediately know that the insertional connection element 3 is mounted in place when the bottom side of the pressing portion 317 abuts against the top side of the crossbeam 2 (see FIG. 7). The provision of the pressing portion 317 also prevents an insertional connection element 3 from being pushed excessively downward into a vertical post 1, or more particularly into the corresponding space 10 for insertional connection. In certain embodiments of the present invention, however, each insertional connection element 3 can, depending on product requirements, have an alternative structure for providing the same function as the pressing portion 317 or the upper fixing plate 23.

[0026] Referring to FIG. 1 to FIG. 4, the bottom end of each supporting rod 4 is configured to be positioned on an insertional connection element 3 and / or a crossbeam 2. In this embodiment, one or more supporting rods 4 are configured to be positioned on the corresponding insertional connection element(s) 3, and one or more supporting rods 4 are configured to be positioned on the corresponding crossbeam(s) 2. In certain embodiments of the present invention, however, the supporting rod(s) 4 can be configured to be positioned on only the insertional connection element(s) 3 or only the crossbeam(s) 2. In addition, the bottom end of each supporting rod 4 is provided with a second elastic position-limiting portion 41. Each second elastic position-limiting portion 41 can be in the form of, for example but not limited to, the spring pin(s) (as shown in FIG. 8A) or a V-shaped elastic fastener (as shown in FIG. 8B).

[0027] The connecting structures of and between a supporting rod 4 and an insertional connection element 3 and the connecting structures of and between a supporting rod 4 and a crossbeam 2 are described as follows. First, referring to FIG. 1 to FIG. 4, the top end of each insertional connection element 3 is provided with two first connecting arms 33 that are spaced apart by a distance, wherein a side of each first connecting arm 33 that is facing another first connecting arm 33 is provided with a first connecting opening 330. Once an insertional connection element 3 is connected to a vertical post 1, the first connecting arms 33 of the insertional connection element 3 are exposed from the vertical post 1; in other words, the insertional connection element 3 is connected to the vertical post 1 in such a way that not the entire insertional connection element 3 extends into the vertical post 1. The second elastic position-limiting portion 41 of a supporting rod 4 can then be connected between the first connecting arms 33 and be positioned in the corresponding first connecting openings 330 such that the supporting rod 4 is fixed on the insertional connection element 3. Next, referring to FIG. 9, the top side of each crossbeam 2 is provided with two second connecting arms 25 that are spaced apart by a distance, wherein each second connecting arm 25 is provided with a second connecting opening 250. The second elastic position-limiting portion 41 of a supporting rod 4 can be connected between the second connecting arms 25 and be positioned in the second connecting openings 250 such that a supporting rod 4 is fixed on a crossbeam 2.

[0028] The top ends of the supporting rods 4 can be directly or indirectly fixed together; that is to say, the fixing method can involve fixing the top ends of each two adjacent supporting rods 4 directly (e.g., through mechanical engagement) or indirectly (i.e., through another element). More specifically, referring to FIG. 10, the supporting rods 4 can be fixedly connected to one another through a fastening member 5. The fastening member 5 is provided with a plurality of hollow tubes 51, and each hollow tube 51 has at least one side provided with a through bore 510. The top end of each supporting rod 4 is provided with a third elastic position-limiting portion 43 whose structure can be one or more spring pins (as shown in FIG. 5 or FIG. 8A), or a V-shaped elastic fastener (as shown in FIG. 6 or FIG. 8B). The top end of each supporting rod 4 can be inserted into the corresponding hollow tube 51 until the third elastic position-limiting portion 43 of the supporting rod 4 extends into the corresponding through bore 510, thereby fixing the supporting rods 4 together.

[0029] It is worth mentioning that, referring back to FIG. 1 to FIG. 3, each vertical post 1, crossbeam 2, or supporting rod 4 of the present invention can, depending on the dimensional requirements of the final product, be a single integrally formed element or assembled from a plurality of elements. For example, one of the supporting rods 4 in FIG. 11 is assembled from two rod elements 4A and 4B. The rod elements 4A and 4B can be connected to each other by one or more spring pins or a V-shaped elastic fastener (e.g., of the configuration of any of the elastic position-limiting portions described above). Similarly, each vertical post 1 or crossbeam 2 can have a similar assembled structure to greatly increase the flexibility of use of the facility structure of the invention. Thus, the pavilion K (i.e., facility structure) of the invention has the following advantages: (1) Simple structural design: The pavilion K (i.e., facility structure) has a simple structural design that allows the pavilion K to be shipped in an unassembled state without an accompanying pack of screws. This not only helps reduce customer complaints associated with a loss of accessories, but also provides better user experience. (2) Highly efficient assembly: The pavilion K (i.e., facility structure) does not require threaded fasteners, so a user does not have to prepare hand tools for threaded connection and can assemble the pavilion K readily with bare hands. This allows the assembly process to be completed rapidly and easily and helps save the tool purchase cost and shorten the assembly time. Even an unexperienced female or senior consumer will be able to complete the assembly within a very short time. (3) Easy disassembly and storage: Thanks to the structural features of spring pins or V-shaped elastic fasteners (e.g., of the configurations of the elastic position-limiting portions disclosed herein), the pavilion K (i.e., facility structure) not only can be easily assembled, but also can be disassembled with the same ease. This structural design facilitates product storage and transportation and helps reduce the space required for storage and transportation, making the product suitable for use in spaces of various sizes.
