The present invention relates to a mounting assembly, and more particularly to the mounting assembly being applied to fix a bathroom accessory.
A conventional mounting assembly is employed to fix bathroom accessory (such as armrest or towel rack) on a wall by way of wall anchors and screw bolts. However, when the wall is hollow and thin, the wall anchors or the screw bolts cannot lock the bathroom accessory on the wall securely.
A mounting mechanism for securing an article to a wall is disclosed in U.S. Pat. No. 7,828,501B2. The mounting mechanism includes an insertion member, a base member, and a tab member. The insertion member has at least one hub formed thereon. The base member has a flange and at least one arm depending from the flange. The flange defines an insertion hole, and the at least one arm includes a guide. When the insertion member is provided in the insertion hole, the guide receives the at least one hub. The guide directs movement of the insertion member relative to the base member. The insertion member and the base member include a ratchet mechanism for maintaining the position of the insertion member relative to the base member. The ratchet mechanism can include a pawl formed on the at least one hub and at least one indentation provided on the guide. The pawl can interact with the at least one indentation. The tab member can be removably coupled to the insertion member. The tab member can be used to articulate the insertion member from an insertion orientation to an installed orientation.
Nevertheless, the mounting mechanism is complicated and is produced at high fabrication cost. In addition, the mounting mechanism is operated troublesomely.
Another mounting mechanism is disclosed in CN 1183333C and contains a metal fixer and a holding assembly. The holding assembly includes two positioning racks capable of being manually snapped off and includes a fitting loop retained on the two positioning racks. A first end of each of the two positioning racks is rotatably connected on the metal fixer. Said each positioning rack is rotated to form a straight line with the metal fixer so that the metal fixer inserts through a through orifice of a substrate and is rotated to be perpendicular to said each positioning rack and to abut against a first side surface of the substrate, and the fitting loop is moved to contact with a second side surface of the substrate along said each positioning rack. Thereafter, a part of said each positioning rack outside the fitting loop is snapped off. Preferably, a threaded nut on the metal fixer is used to fix the bathroom accessory, and the substrate is a thin wall or a hollow wall.
The metal fixer is too thin to support a heavy object, and the two positioning racks are operated inconveniently and interfere with each other.
The present invention has arisen to mitigate and/or obviate the afore-described disadvantages.
The primary objective of the present invention is to provide a mounting assembly which is simplified and is produced at low fabrication cost.
To obtain the above objective, a mounting assembly provided by the present invention contains: a body, an engagement strap, and a retaining loop.
The body is an elongated plate and includes an abutting plane, an opposite face opposite to the abutting plane, a threaded orifice passing through the abutting plane and the opposite face, a top edge, and a bottom edge. A distance between the threaded orifice and the top edge is longer than a distance between the threaded orifice and the bottom edge, and the abutting plane has a connection seat arranged on a lower end thereof adjacent to the threaded orifice.
The engagement strap includes a coupling portion formed on a first end thereof, a pull ring mounted on a second end thereof, a toothed section arranged between the coupling portion and the pull ring, and a fitting section defined between the toothed section and the pull ring. The coupling portion of the engagement strap is parallelly in connection with the connection seat of the body so that the engagement strap is limited on an insertion position, and the engagement strap being rotated on an installation position perpendicular to the body. The body and a part of the engagement strap are inserted through an affix hole of a wall on the insertion position.
The retaining loop includes an opening defined on a peripheral side thereof, and the retaining loop includes a locking slot communicating with the opening, wherein the locking slot accommodates the fitting section of the engagement strap, and as the retaining loop moves to the toothed section of the engagement strap, the locking slot movably engages with the toothed section until the retaining loop contacts with the wall; and wherein another part of the engagement strap outside the retaining loop is cut or is snapped off.
Preferably, the abutting plane of the body has a recess formed on a bottom thereof and extending toward the connection seat, and the abutting plane has a first stop fringe arranged on a bottom of the recess so as to stop the engagement strap, hence the engagement strap is limited on the insertion position. The connection seat has a notch communicating with the recess and has a second stop fringe defined thereon so as to stop the engagement strap, hence the engagement strap is limited and rotated on the installation position.
Preferably, the connection seat further has two apertures defined on two sides of the notch, respectively; the coupling portion of the engagement strap has two flexible posts extending outwardly from two sides thereof respectively, and each of the two flexible posts is rotatably connected with each of the two apertures of the connection seat.
Preferably, the abutting plane of the body has a protrusion surrounding the threaded orifice and configured to retain in the affix hole of the wall.
Preferably, the body further includes a holder and a screw nut fixed in the holder; the screw nut has the threaded orifice defined therein; and the holder has two through orifices arranged on two ends of the screw nut, individually.
Preferably, the holder is injection molded from plastic material and covers the screw nut.
Preferably, the opposite face of the body obliquely extends to the top edge and the bottom edge from the threaded orifice so that a thickness of the body on the threaded orifice is more than those of the top edge and the bottom edge.
Preferably, the toothed section of the engagement strap has multiple first teeth; and the locking slot of the retaining loop has at least one second tooth, such that at least one of the multiple first teeth of the engagement strap retains with the at least one second tooth of the locking slot of the retaining loop.
Preferably, a width of the fitting section of the engagement strap is less than the toothed section, hence when the fitting section moves into the locking slot via the opening, the toothed section is not removed from the locking slot backward.
Preferably, the retaining loop further includes a limiting rib arranged on the peripheral side thereof so as to engage with the affix hole of the wall.

The body 10, as shown in
The engagement strap 20 includes a coupling portion 21 formed on a first end thereof, a pull ring 22 mounted on a second end thereof, a toothed section 23 arranged between the coupling portion 21 and the pull ring 22, and a fitting section 24 defined between the toothed section 23 and the pull ring 22. The coupling portion 21 of the engagement strap 20 is parallelly in connection with the connection seat 16 of the body 10, and the engagement strap 20 is limited on an insertion position after being inserted into an affix hole 2a of a wall 2 with the body 10, as illustrated in

Referring to
The opposite face 12 of the body 10 obliquely extends to the top edge 14 and the bottom edge 15 from the threaded orifice 13 so that a thickness of the body 10 on the threaded orifice 13 is more than those of the top edge 14 and the bottom edge 15, hence when the body 10 is inserted into a fixing space behind the wall 2 via the affix hole 2a, it is adjustably moved and is positioned easily, for example, the body 10 is moved to a vertical state and abuts against an internal face 2b of the wall 2, as shown in
As illustrated in
A width of the fitting section 24 of the engagement strap 20 is less than the toothed section 23, hence when the fitting section 24 moves into the locking slot 32 via the opening 31, the toothed section 23 is not removed from the locking slot 32 backward, and the engagement strap 20 is pushed forward the internal face 2b of the wall 2 until the retaining loop 30 abuts against an external face 2c of the wall 2.
With reference to
In a test, when the bathroom accessory is an armrest, the mounting assembly 1 of the present invention is capable of supporting the action force of 300 lb.
The affix hole 2a is drilled on the wall 2 and its diameter is 24.5 mm.
As the engagement strap 20 is limited on the insertion position after being inserted into the affix hole 2a of the wall 2 with the body 10, the body 10 is parallel to the engagement strap 20 so as to be inserted into the wall 2 via the affix hole 2a, as shown in
As the wall 2 is hollow, a reinforcement fence 3 is arranged behind the wall 2 so that when the top edge 14 of the body 10 contacts with the reinforcement fence 3, the body 10 is moved to the vertical state by using the threaded orifice 13 as illustrated in
Referring to
As the wall 2 is solid, the body 10 is adjustably moved and positioned after inserting through the affix hole 2a, and the engagement strap 20 is pulled backward, thus abutting the mounting assembly 1 against the wall 2.
Accordingly, the mounting assembly 1 is fixed and abuts against the wall 2 easily and has strong support capacity. Preferably, the mounting assembly 1 is simplified and is produced at low fabrication cost.
