Description
CROSS REFERENCE TO RELATED APPLICATIONS
[0001] This Application claims priority of China Patent Application
No. 201410608800.1, filed on Oct. 31, 2014, the entirety of which
is incorporated by reference herein.
BACKGROUND OF THE INVENTION
[0002] 1. Field of the Invention
[0003] The invention relates to a clamp, and more particularly to a
hook clamp.
[0004] 2. Description of the Related Art
[0005] It is important for most people to have a good sleep,
especially in the modern era where people lead such busy
lifestyles. A comfortable bed is required for the good sleep.
However, a bottom sheet laid on a mattress often slides to the end
of the bed after one night's sleep, and people need to remake the
bottom sheet every time before sleeping. Further, the sliding
bottom sheet is generally wrinkled and people lying thereon do not
feel comfortable. Although some beds have railings, the sliding of
the bottom sheet still cannot be prevented. Even worse, the
wrinkling problem may become more serious and more ironing work is
required.
BRIEF SUMMARY OF THE INVENTION
[0006] The invention provides a hook clamp capable of clamping or
hooking different kinds of bottom sheets, thereby preventing the
sliding and wrinkling of a bottom sheet and improving the user
experience.
[0007] The hook clamp in accordance with an exemplary embodiment of
the invention includes a clamping module and a base. The clamping
module includes a curved member and a movable member. The curved
member includes a head and a first end portion opposite to the
head. The movable member includes a groove corresponding to the
curved member and an engaging member corresponding to the head. The
base includes a rail and a limiting member. The rail is configured
to guide a motion of the movable member. The limiting member is
configured to limit the curved member to move between a first
position and a second position. The head is pushed by the limiting
member to engage the engaging member when the movable member moves
along the rail to the first position. The first end portion of the
curved member is pushed by the limiting member so that the head is
separated from the engaging member to serve as a hook when the
movable member moves along the rail to the second position.
[0008] In another exemplary embodiment, the curved member is a
rocker, the engaging member of the movable member is an engaging
groove, the curved member further includes a second end portion
from which the head extends downward, a plurality of connecting
posts disposed on two lateral sides of the curved member, and the
movable member further includes a rocker groove corresponding to
the rocker, a plurality of notches corresponding to the connecting
posts, and a force receiving part.
[0009] In yet another exemplary embodiment, the base further
includes a securing flange.
[0010] In another exemplary embodiment, the curved member further
includes a first stopping member transversely disposed on the first
end portion of the curved member.
[0011] In yet another exemplary embodiment, the movable member
further includes a second stopping member disposed beside an end of
the rocker groove.
[0012] The invention further provides a bed. The bed in accordance
with an exemplary embodiment includes a mattress, a bottom sheet,
and a hook clamp. The hook clamp is mounted on the mattress for
securing the bottom sheet to the mattress.
[0013] In another exemplary embodiment, the mattress is an
inflatable mattress.
[0014] In yet another exemplary embodiment, the hook clamp is
welded to the inflatable mattress.
[0015] A detailed description is given in the following embodiments
with reference to the accompanying drawings.

DETAILED DESCRIPTION OF THE INVENTION
[0028] The following description is of the best-contemplated mode
of carrying out the invention. This description is made for the
purpose of illustrating the general principles of the invention and
should not be taken in a limiting sense. The scope of the invention
is best determined by reference to the appended claims.
[0029] Referring to FIGS. 1 to 3, a hook clamp of the invention
includes at least one clamping module. The clamping module includes
a curved member and a movable member 20. In this embodiment, the
curved member is a rocker 10. The rocker 10 includes a curved body,
a head 11 disposed on an end portion of the curved body, two
connecting posts 12 disposed on two lateral sides of the curved
body, and a first stopping member disposed on the other end portion
of the curved body. The first stopping member is a rib 13 in this
embodiment.
[0030] The movable member 20 includes a groove adapted to the
curved member, and an engaging member adapted to the head 11. In
this embodiment, the groove is a rocker groove 23 adapted to the
rocker 10, and the engaging member is an engaging groove 21 adapted
to the head 11. The movable member 20 further includes notches 22
adapted to the connecting posts 12, and a force receiving part 24.
The rocker 10 is rotatably connected to the movable member 20
through the connecting posts 12 rotatably disposed in the notches
22. As shown in FIGS. 2 and 3, the movable member 20 further
includes a second stopping member. In this embodiment, the second
stopping member is a boss 25 disposed beside an end of the rocker
groove 23.
[0031] Referring to FIG. 4, the hook clamp of the invention further
includes a base 30. The base 30 includes a rail 31 adapted to the
movable member 20 and a limiting member 32 for limiting a motion of
the rocker 10. Referring to FIGS. 5 and 6, the base 30 further
includes a securing flange 33 through which the base 30 can be
secured to a bed. In this embodiment, the bed is an inflatable bed
and the hook clamp is welded to the inflatable bed.
[0032] Referring to FIG. 5, when the force receiving part 24 is
pushed up to be moved along the rail 31 to a first position, the
limiting member 32 pushes the head 11 downward so that the head 11
engages with the engaging groove 21. Referring to FIG. 6, when the
movable member 20 is pulled down to be moved along the rail 31 to a
second position, the limiting member 32 pushes down the end portion
of the rocker 10 on which the rib 13 is disposed so that the head
11 moves up to leave the engaging groove 21. As a result, the head
11 becomes a hook extending at a predetermined angle and capable of
pulling or hooking something. During the process of pushing/pulling
the movable member 20, the rib 13 is able to prevent separation of
the rocker 10 from the movable member 20, and the bosses 25 are
able to prevent separation of the movable member 20 from the base
30.
[0033] Referring to FIG. 7a, a plurality of hook clamps 60 are
disposed on lateral sides of an inflatable bed 50. The hook clamps
60 are able to clamp a bottom sheet 40 which has no elastic band,
in accordance with the following way: the bottom sheet 40 is placed
on the inflatable bed 50 to cover the hook clamp 60. The outer edge
of the bottom sheet 40 is put against the movable member 20 by two
fingers. The force receiving part 24 with the bottom sheet 40 is
moved upwards by the fingers so that the head 10 is lowered down
with the movement of the force receiving part 24 to engage the
engaging groove 21 as shown in FIGS. 7d and 7e and thus the bottom
sheet 40 is clamped between the head 11 and the engaging groove 21.
When the force receiving part 24 is pulled downward, the end
portion of the rocker 10 with the rib 13 is lowered so that the
head 11 is lifted and separated from the engaging groove 21 and the
bottom sheet 40 is not clamped by the hook clamp and can be
removed.
[0034] Alternatively, the hook clamps 60 are able to hook a fitted
sheet 70 which has an elastic band 71 disposed at the outer edges
thereof as shown in FIG. 8a. In this example, the head 11 of the
rocker 10 is separated from the engaging groove 21 to serves as a
hook for hooking the elastic band 71 as shown in FIG. 8b. Thus, the
fitted sheet 70 is secured to the inflatable bed 50 by the hook
clamps 60.
[0035] From the above descriptions, it is understood that
embodiments of the hook clamp of the invention prevent the sliding
and winkles of a bottom sheet so as to improve sleep quality and
reduce the time for making bed.
[0036] While the invention has been described by way of example and
in terms of preferred embodiment, it is to be understood that the
invention is not limited thereto. To the contrary, it is intended
to cover various modifications and similar arrangements (as would
be apparent to those skilled in the art). Therefore, the scope of
the appended claims should be accorded the broadest interpretation
so as to encompass all such modifications and similar
arrangements.
